Background and objective: An agrovoltaic system is a power generation method applying photovoltaics (PV) to crops cultivated on a farm. Usually, the PV system covers less than 30% of the upper surface of crops on the ground. If the PV system covers the upper layer of the crops, the yield will decrease by 15-20% due to the shading of the PV module. This study was carried out to investigate the effects of red supplemental light-emitting diode (LED) lighting under the PV system on growth and agronomic traits of green onions.Methods: To resolve the issue about decreasing yield, we constructed a 50 kW agrovoltaic system with the red (660 nm peak) LED dimming facility on the farm with 3 different plots for comparison. The 1st was PV + LED (two parts of dimming area: 3 hours and 6 hours). The second was only PV, and the last was a reference for comparison of yield (control plot). We transplanted uniform seedlings of green onions on three areas of the farm on June 23, 2020. We used red LED lighting for 3 hours and 6 hours after sunset and harvested green onions on October 25, 2020. We used less than 1% of electricity of total power generated by the agrovoltaic system for supplemental LED lighting.Results: The result of harvesting under the agrovoltaic system with 3 hours of lighting showed that there was 38% more yield than the control plot. We also discovered the optimal amount of supplemental LED lighting because even 6 hours of lighting were not better than 3 hours.Conclusion: Applying supplemental LED lighting after sunset can compensate for the yield decrease. The LED supplemental lighting for 3 hours is optimal for crop harvest. We expect that this system can be helpful to farmers who want to construct an agrovoltaic system.
背景与目的:农业光伏发电系统是一种利用光伏发电(PV)在农场种植作物的发电方法。通常,光伏系统覆盖不到30%的作物上表面的地面。如果光伏系统覆盖作物的上层,由于光伏组件的遮阳,产量将下降15-20%。本试验旨在研究光伏系统下红色发光二极管(LED)照明对大葱生长和农艺性状的影响。方法:为解决产量下降的问题,我们在农场搭建了一个50 kW的农光伏系统,并在3个不同的地块进行比较。第一种是PV + LED(调光区域分为3小时和6小时两部分)。第二个仅为PV,最后一个为产量比较参考(对照图)。2020年6月23日,我们在农场的三个区域移植了均匀的大葱幼苗。我们在日落后使用红色LED照明3小时和6小时,并于2020年10月25日收获大葱。我们用不到农业光伏发电系统总发电量的1%的电力来补充LED照明。结果:在农光伏系统下光照3 h的收获结果显示,产量比对照提高38%。我们还发现了补充LED照明的最佳数量,因为即使6小时的照明也不会超过3小时。结论:日落后采用LED补充照明可以弥补产量的下降。LED补充照明3小时最适合作物收获。希望该系统能对想要构建农光伏发电系统的农民有所帮助。

Background and objective: This study was conducted to investigate the effect of the cultivation environment of Allium microdictyon in forest cultivation on leaf growth characteristics and antioxidant activity.Methods: One-year seedlings of Allium microdictyon were planted in test sites with different elevations and slopes in a forest. Each test site was selected on the south-facing slope and north-facing slope each at 700 m and 500 m above sea level, and each test site was created within a straight-line distance of 200m. Leaf characteristics were investigated and antioxidant enzyme activity were measured from April to June the following year after planting.Results: The 500m sites reached the maximum leaf size about a week earlier than the 700m sites, and the maximum leaf area was doubled in the same periods and higher in the south-facing slope than the north-facing slope. In the south-facing slope in Misan-ri, where the growth was the fastest, the total nitrogen (T-N) in soil also showed a high content. Regarding the antioxidant activity according to the planting site and harvest time, there was little difference in superoxide dismutase (SOD), but catalase increased until the time of release and then decreased thereafter. Malondialdehyde (MDA), a measure of the degree of lipid peroxidation, decreased until the harvest date and then slightly increased.Conclusion: Based on the results of this study, it is possible to control the harvest date by adjusting the location environment such as the slope direction of the sites for forest cultivation of Allium microdictyon. Catalase and MDA tended to be proportional or inversely proportional depending on the harvest date, serving as most active indicators of change in physiological activity.
背景与目的:本研究旨在探讨林下小葱栽培环境对其叶片生长特性和抗氧化活性的影响。方法:在森林中不同海拔和坡度的试验点种植小葱一年生幼苗。每个测试场地分别选择在海拔700米和500米的朝南斜坡和朝北斜坡上,每个测试场地都在200米的直线距离内创建。在种植后的第二年4月至6月,对叶片特性进行了调查,并测定了抗氧化酶活性。结果:500米处的最大叶面积比700米处早一周左右达到最大,并且最大叶面积在同一时期翻了一番,并且朝南坡的最大面积高于朝北坡。在密山里生长最快的南坡,土壤中的总氮含量也很高。在抗氧化活性方面,根据种植地点和收获时间的不同,超氧化物歧化酶(SOD)差异不大,但过氧化氢酶在释放前增加,然后下降。丙二醛(MDA)是衡量脂质过氧化程度的指标,在收获日期之前一直在下降,然后略有上升。结论:根据本研究的结果,可以通过调整小葱林培育点的坡度方向等位置环境来控制收获期。根据收获日期的不同,过氧化氢酶和MDA往往成正比或成反比,是生理活性变化的最活跃指标。

Background and objective: The objective of this study was to produce Asiatic hybrid lily with more than two flowers in one year starting from bulbils. This study was to force 'Beni no Mai' bulbils influenced by harvesting date, flower bud removal, and temperature manipulation and to evaluate dormancy and maturity by nuclear magnetic resonance imaging (NMRI) and carbohydrates analysis.Methods: In experiment 1, bulbils were harvested at 0-30 days after anthesis (DAA), and were divided into 7 stages. And, soluble monosaccharides and monosaccharide constituents of bulbils were analyzed. In experiment 2, flower buds of plants that flowered on 21 April were not removed or removed on 1, 13, and 25 April. Bulbils harvested were divided into four groups and planted after cold treatment. In experiment 3, bulbils received a sequential temperature (SEQ CD) treatments for three weeks at 2.5, 5.0, and 7.5°C, 1 week at 10, 12.5, and 15°C, and 3 weeks at 2.5, 5.0, and 7.5°C. In experiment 4, bulbils were harvested 0-70 DAA, and were subjected to spin-spin lattice relaxation time by NMRI.Results: The bulbils harvested at 30 DAA produced two flowers within 282 days, and were better in growth. The bulbils harvested at 30 DAA showed higher concentration of soluble glucose and lower concentration of non-cellulosic neutral glucose. Growth of bulbils removed flower buds before flowering were better than those of bulbils that flower bud was removed at anthesis and 13 Apr. However, the number of flowers of bulbils harvested from plants removed flower buds on 1 Apr. were less than 2. The SEQ CD treatment of 7.5°C/3W-15°C/1W-5°C/3W in bulbils could produce the plants with 2.2 flowers within 300 days after planting. When bulbils were harvested at 0-28 DAA, yellow color corresponding to T2 relaxation time of 15-20 ms was dominant, and bulbils harvested at 56-70 DAA showed T2 relaxation time of 35-50 ms and 50-100 ms.Conclusion: Considering the results of soluble carbohydrate content and T2 relaxation time of bulbils, it was found that the bulbils had a shallower dormancy and were more mature at 30-42 DAA than before 28 DAA. Also, when these bulbils were planted after SEQ CD treatment at 7.5°C/3W-15°C/1W-5°C/3W, plants with two or more flowers could be produced within one year.
背景与目的:本研究的目的是从鳞茎开始,在一年内培育出两花以上的亚洲杂交百合。本研究采用核磁共振成像(NMRI)和碳水化合物分析方法,对采收日期、去花芽和温度处理对‘贝尼麦’球茎的影响进行了研究。方法:试验1在开花后0 ~ 30 d采收球茎,分为7期。并对球芽的可溶性单糖和单糖成分进行了分析。在试验2中,4月21日开花的植株的花蕾在4月1日、13日和25日均未脱落或脱落。将收获的球茎分成四组,经冷处理后种植。在实验3中,球茎在2.5、5.0和7.5℃下连续温度(SEQ CD)处理3周,在10、12.5和15℃下处理1周,在2.5、5.0和7.5℃下处理3周。实验4取0 ~ 70 DAA的球泡,用核磁共振成像(NMRI)测量自旋-自旋晶格弛豫时间。结果:30daa收获的球茎在282天内开出2朵花,生长较好。30daa收获的球茎中可溶性葡萄糖浓度较高,非纤维素中性葡萄糖浓度较低。开花期前去花芽的球茎生长情况好于开花期和4月13日去花芽的球茎,而4月1日去花芽的球茎所收获的球茎花数少于2朵。球茎温度为7.5°C/3W-15°C/1W-5°C/3W的SEQ CD处理可在种植后300天内产生2.2朵花。0-28 DAA收获时,T2松弛时间为15-20 ms对应的黄色占主导地位,56-70 DAA收获时,T2松弛时间为35-50 ms和50-100 ms。结论:综合球茎可溶性碳水化合物含量和T2松弛时间的结果,发现30-42 DAA时球茎休眠较28 DAA前更浅,球茎成熟程度更高。在7.5°C/3W-15°C/1W-5°C/3W条件下进行SEQ CD处理后种植,一年内可产生2朵或更多花。

Background and objective: To deal with recent issues such as climate change, rural aging, food security, and the Fourth Industrial Revolution, there is a growing interest in smart farms that can efficiently produce food with ICT. In response to the international issues, this study analyzed articles on smart farms published in international journals and KCI journals as well as Instagram hashtags through text mining and identified relevant research trends and public awareness.Methods: This study collected total 584 articles on smart farms from 2010 to 2021 and hashtags in Instagram posts uploaded in 2021. To improve the reliability of the analysis results, nouns were exclusively extracted from the abstracts and hashtags, and data preprocessing was performed by removing nouns that appear customarily and combining synonyms. After that, we analyzed frequency, degree centrality, betweenness centrality, and topic modeling.Results: The analysis results of words with high frequency and centrality by research data are as follows. KCI and international journal articles had a tendency to mainly focus on ICT system development for efficient operation of smart farms. However, KCI articles considered relevant policies to establish the technologies. On the other hand, international journal articles tended to conduct research on smart farms in a wider area of agricultural fields than KCI articles. The main topics on Instagram were diet food, rural migration, and urban agriculture. This result shows that healthy food, experiences, and education through smart farms are gaining public interest.Conclusion: Currently, there is insufficient analysis of research trends in smart farms. In this vein, this study has significance as it included academic trends and public awareness by considering both research articles and Instagram posts. We expect the results of this study to be used as useful data for decision making to set the research and policy directions required to advance smart farms in the future.
背景和目标:为了应对气候变化、农村老龄化、粮食安全和第四次工业革命等近期问题,人们对能够利用信息和通信技术高效生产粮食的智能农场越来越感兴趣。为了应对国际问题,本研究通过文本挖掘分析了国际期刊、KCI期刊以及Instagram标签上发表的关于智能农场的文章,并确定了相关的研究趋势和公众意识。方法:本研究收集了2010年至2021年关于智能农场的584篇文章和2021年上传的Instagram帖子中的标签。为了提高分析结果的可靠性,只从摘要和标签中提取名词,并通过删除习惯出现的名词和组合同义词来进行数据预处理。然后,我们分析了频率、度中心性、介数中心性和主题建模。结果:研究数据对高频词和中心词的分析结果如下。KCI和国际期刊文章倾向于主要关注智能农场高效运营的ICT系统开发。然而,KCI的文章考虑了建立这些技术的相关政策。另一方面,国际期刊文章倾向于在比KCI文章更广泛的农业领域对智能农场进行研究。Instagram上的主要话题是减肥食品、农村移民和城市农业。这一结果表明,通过智能农场提供的健康食品、体验和教育正在引起公众的兴趣。结论:目前,对智能农场的研究趋势分析不足。有鉴于此,这项研究具有重要意义,因为它通过考虑研究文章和Instagram帖子,纳入了学术趋势和公众意识。我们预计这项研究的结果将被用作决策的有用数据,以确定未来推进智能农场所需的研究和政策方向。

Background and objective: With the desire for a healthy life and healing amid the environmental changes caused by the global climate crisis, and the COVID-19 pandemic, people's interest in care farming (CF) is growing. Therefore, this study aims to derive implications for the revitalization of CF by empirically analyzing the relationship between the effects on the intention to participate in CF.Methods: A survey was conducted (June 16, 2022 - July 25, 2022) using a structured questionnaire targeting city residents in Seoul and the metropolitan area to identify their intention to participate in CF. For the collected data of 255 copies of the questionnaire finally selected here, basic statistical analysis, correlation analysis, reliability, factor analysis, regression analysis, and moderating effect verification were performed to verify hypotheses established based on the research model. The Jamovi statistical package was used.Results: The results of this study are as follows. First, self-leadership and perceptual factor had a significantly positive (+) effect on the intention to participate in CF. Second, farming experience and mentoring, which are pulling factors between self-leadership and intention to participate in CF, had a statistically significant moderation effect. Third, farming experience, which is one of the pull factors between perceptual factor and intention to participate in CF, had a statistically significant moderation effect, but mentoring did not.Conclusion: Based on the results, this study determined the causal relationship between self-leadership and perceptual factor as a determinant affecting urban residents' intention to participate in CF. In addition, the necessity of a policy and practical approach was suggested depending on the level of farming or mentoring experience by verifying the moderation effect of pull factors.
背景与目的:在全球气候危机和COVID-19大流行造成的环境变化中,随着人们对健康生活和治疗的渴望,人们对护理农业(CF)的兴趣日益浓厚。因此,本研究旨在通过实证分析影响CF参与意愿的关系,得出CF振兴的启示。以首尔和首都圈城市居民为对象(2022年6月16日- 2022年7月25日),采用结构化问卷调查方式,对其参与CF的意向进行调查。对最终选取的255份问卷收集数据进行基本统计分析、相关分析、信度分析、因子分析、回归分析和调节效果验证,验证基于研究模型建立的假设。使用Jamovi统计软件包。结果:本研究结果如下:第一,自我领导和知觉因素对参与CF意愿具有显著的正(+)作用。第二,作为自我领导与参与CF意愿之间的拉动因素,农事经历和师徒关系具有显著的调节作用。第三,作为感知因素与CF参与意愿之间的拉动因素之一,务农经验具有显著的调节作用,而师徒关系不具有显著的调节作用。结论:基于研究结果,本研究确定了自我领导与感知因素之间的因果关系是影响城市居民参与CF意愿的决定因素,并通过验证拉动因素的调节作用,提出了根据农业或师徒经验水平制定政策和实践方法的必要性。

Background and objective: Plant viruses are major obstacles to enhancing crop productivity in both agriculture and horticulture throughout the world, resulting in losses of several billion dollars every year. Controlling viruses is arduous, so agrochemicals are widespread. To minimize the usage of those, this study's objective was to assess bacterial cultures supernatants on pepper mild mottle virus (PMMoV) in chili pepper plants and identify its secondary metabolites.Methods: This 48-h grown Pseudomonas putida (PP) and Bacillus licheniformis (BL) cultures supernatants were foliar sprayed separately in chili pepper plants 24-h before PMMoV inoculation (T1), and 24-h before and after PMMoV inoculation (T2), 2wpi (week's post inoculation), the virus titer was determined by using a double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA), and the supernatants were extracted with ethyl acetate and concentrated by rota-evaporation before being analyzed in gas chromatography mass spectrometry (GC-MS).Results: The culture supernatants of PP and BL inhibit PMMoV by 43-47% in both the treatments (T1 & T2) compared to the control. The GC-MS chromatogram of two cultures of supernatants identified the molecules of cyclo (Pro-Val), cyclo (Pro-Leu), and cyclo (Phe-Pro). Commercial forms of these three molecules at three concentrations showed a hypersensitive response, ranging from 45-65% for PMMoV in Nicotiana glutinosa.Conclusion: The results revealed that supernatants of PP and BL-containing compounds have biological control of PMMoV in chili pepper plants.
背景和目的:植物病毒是提高世界农业和园艺作物生产力的主要障碍,每年造成数十亿美元的损失。控制病毒是一项艰巨的任务,因此农用化学品广泛使用。为了尽量减少这些病毒的使用,本研究的目的是评估辣椒植物中辣椒轻度斑点病毒(PMMoV)的细菌培养上清液,并鉴定其次级代谢产物。方法:将培养48小时的恶臭假单胞菌(PP)和地衣芽孢杆菌(BL)培养上清液分别在辣椒接种PMMoV前24小时(T1)、接种前后24小时(T2)、接种后2周(2wpi)进行叶面喷雾,用双抗体夹心酶联免疫吸附试验(DAS-ELISA)测定病毒滴度,结果:与对照组相比,PP和BL的培养上清液对PMMoV的抑制率分别为43~47%。两种上清液培养物的GC-MS色谱图鉴定了环(Pro-Val)、环(Pro-Leu)和环(Phe-Pro)的分子。这三种分子在三种浓度下的商业形式显示出对粘性烟草中PMMoV的过敏反应,范围为45-65%。结论:含PP和BL化合物的上清液对辣椒植株PMMoV具有生物防治作用。

Background and objective: Gentrification generally refers to changes in residents or operators in neighborhoods by investment in capital, a phenomenon in which wealthy or young professionals replace existing residents or operators in socioeconomic terms. Although conducted mainly in capitalist cities, some studies dealt with socialist systems or state-led gentrification. We intended to demonstrate the gentrification in North Korean by examining the cases of the socialist system and state-led gentrification and looking at urban development and urban space restructuring in Pyongyang Metropolitan Area in North Korea.Methods: To build up methodological framework of the study, we reviewed previous literature that deals with gentrification in capitalist cities, socialist systems, and state-led planning. About the gentrification phenomenon in North Korea, we examined secondary data of North Korea refugee interviews with North Korea government documents and research papers about Pyongyang's building and real estate development. Then, we compared gentrification in capitalist cities, socialist systems (or state-led planning), and North Korea.Results: Gentrification in capitalist cities, socialist system and North Korea differs in their enabling conditions, gentrifying agents, gentrifiers, and processes. National and local governments, usually with the North Korea communist party, play a leading role as gentrifying agents through their public policy. In the gentrification processes, there is an increasing gap between rich and poor and spatial separation between them, especially when displaced households being pushed out of town in North Korea.Conclusion: Urban development and apartment construction in Pyongyang shows the possibility of developing into existing gentrification, and if the private sector that leads gentrification occurs and at the same time, spatial replacement by privileged or upper classes appears, it will be clear that it is a kind of gentrification under the command economy.
背景和目的:绅士化通常是指通过投资资本来改变社区的居民或经营者,这是一种富有或年轻的专业人士在社会经济方面取代现有居民或经营者的现象。尽管主要在资本主义城市进行,但一些研究涉及社会主义制度或国家领导的士绅化。我们试图通过考察朝鲜社会主义制度和国家主导的士绅化的案例,并考察朝鲜平壤都会区的城市发展和城市空间结构,来展示朝鲜的士绅主义。方法:为了建立研究的方法论框架,我们回顾了以前关于资本主义城市中产阶级化、社会主义制度和国家主导的计划的文献。关于朝鲜的士绅化现象,我们用朝鲜政府文件和关于平壤建筑和房地产开发的研究论文检查了朝鲜难民访谈的二次数据。然后,我们比较了资本主义城市、社会主义制度(或国家主导的计划)和朝鲜的绅士化。结果:资本主义城市、社会主义制度和朝鲜的绅士化在其有利条件、绅士化代理人、绅士化者和过程方面有所不同。国家和地方政府,通常与朝鲜共产党一起,通过其公共政策发挥着绅士化代理人的主导作用。在士绅化过程中,贫富差距和空间分隔越来越大,尤其是在朝鲜流离失所的家庭被赶出城镇时。结论:平壤的城市发展和公寓建设显示出向现有士绅化发展的可能性,如果主导士绅化的私营部门出现,同时出现特权阶层或上层阶级的空间替代,那么这将是一种命令经济下的士绅化。

Background and objective: Artificial environments have been known to negatively affect neuropsychological activities. Healthcare workers who are under high psychological and physiological stress often spend long hours at a time. Recently, many studies have been conducted to reveal the healing effects of natural environments, but few studies have been conducted on healthcare workers. Therefore, this study aims to investigate the effect of green walls in medical facilities on the hemodynamics of the prefrontal cortex in healthcare workers.Methods: Eleven healthy adults working in a medical institution participated in the experiment, in which they rested for 10 minutes in a room with green walls and in a control room. To compare the physiological and psychological changes between the green wall room and the control room, we used various measurements, such as near-infrared spectroscopy in the prefrontal area (NIRS), heart rate variability (HRV), blood pressure (BP), and pulse rate (PR). Psychological tests were also conducted using the Profile of Mood States (POMS), the State-Trait Anxiety Inventory (STAI), the Perceived Restorativeness Scale (PRS), and the Zucherman Inventory of Personal Reaction Scale (ZIPERS).Results: The oxyhemoglobin concentration in the frontal lobe significantly decreased on both the left and right sides in the green wall room compared to the control room. Green walls significantly activated the parasympathetic nervous system and inhibited the sympathetic nervous system compared to the control room. In addition, psychological reactions increased positive emotions and decreased negative emotions.Conclusion: Green walls in medical facilities could be an effective way to promote physiological relaxation and health by reducing physiological hemodynamics in the prefrontal cortex evoked by psychological stress in healthcare workers. This study implies that green walls can be used as an effective means of stress reduction and relaxation.
背景和目的:众所周知,人工环境会对神经心理活动产生负面影响。处于高度心理和生理压力下的医护人员通常一次要花很长时间。最近,已经进行了许多研究来揭示自然环境的愈合效果,但很少对医护人员进行研究。因此,本研究旨在研究医疗设施中的绿色墙壁对医护人员前额叶皮层血流动力学的影响。方法:11名在医疗机构工作的健康成年人参加了实验,他们在绿色墙壁的房间和控制室休息了10分钟。为了比较绿墙室和控制室之间的生理和心理变化,我们使用了各种测量方法,如前额叶区域的近红外光谱(NIRS)、心率变异性(HRV)、血压(BP)和脉搏率(PR)。还使用情绪状态档案(POMS)、状态特质焦虑量表(STAI)、感知恢复能力量表(PRS)、,和Zucherman个人反应量表(ZIPERS)。结果:与对照室相比,绿墙室左右两侧额叶的氧合血红蛋白浓度均显著降低。与对照室相比,绿色墙壁显著激活了副交感神经系统,抑制了交感神经系统。此外,心理反应增加了积极情绪,减少了消极情绪。结论:医疗设施中的绿墙可以通过降低医护人员心理压力引起的前额叶皮层生理血流动力学来促进生理放松和健康。这项研究表明,绿色墙壁可以作为一种有效的手段来减少和放松应力。

Background and objective: Plants are a natural and environmentally friendly way to improve indoor air quality. To evaluate indoor air quality, it is important to continuously measure and identify the influencing factors. This study aimed to identify the factors affecting PM2.5 concentration in indoor spaces with indoor garden installations.Methods: Factors influencing the concentration of indoor, airborne PM2.5 were monitored based on Internet of Things (IoT) technology. Ten households in South Korea were surveyed and categorized into Groups A (households without an indoor garden) and B (households with an indoor garden). An IoT-based device was used to monitor the indoor PM2.5 concentration and several environmental factors, including the outdoor PM2.5 (µg⋅m-3) and carbon dioxide (mL⋅m-3) concentrations, temperature (°C), and relative humidity (%). Further, the seasonal (spring, summer, fall, and winter) and temporal (dawn, morning, afternoon, and evening) variations in indoor PM2.5 concentration were monitored.Results: The indoor PM2.5 concentration decreased from 17.7 µg⋅m-3 to 16.7 µg⋅m-3, and from 15.5 µg⋅m-3 to 12.5 µg⋅m-3 in Groups A and B, respectively. A regression analysis showed that the indoor PM2.5 concentration was not significantly affected by the installation of the indoor garden (living rooms: p = .1577; kitchen: p = .4974); however, was influenced by the outdoor air conditions, as well as seasonal and temporal factors. Additionally, a subgrouping model demonstrated a statistical relationship between indoor garden installation and the environmental factors.Conclusion: These findings can assist in establishing guidelines for indoor air quality management.
背景与目的:植物是改善室内空气质量的一种自然且环保的方式。为了评价室内空气质量,对影响因素进行持续的测量和识别是非常重要的。本研究旨在通过室内花园装置确定影响室内空间PM2.5浓度的因素。方法:基于物联网技术监测室内、空气中PM2.5浓度的影响因素。对韩国10个家庭进行了调查,分为A(没有室内花园的家庭)和B(有室内花园的家庭)两组。采用物联网设备监测室内PM2.5浓度及室外PM2.5(µg⋅m-3)、二氧化碳(mL⋅m-3)浓度、温度(°C)、相对湿度(%)等环境因子。此外,还监测了室内PM2.5浓度的季节(春、夏、秋、冬)和时间(黎明、早晨、下午和晚上)变化。结果:A组和B组室内PM2.5浓度分别由17.7µg⋅m-3和15.5µg⋅m-3降低至12.5µg⋅m-3。回归分析显示,室内PM2.5浓度不受室内花园设置的显著影响(客厅:p = .1577;厨房:p = .4974);然而,受室外空气条件以及季节和时间因素的影响。此外,一个亚分组模型显示了室内花园安装与环境因素之间的统计关系。结论:这些发现有助于建立室内空气质量管理的指导方针。

Background and objective: There have been an increasing number of migrant women in Korea. However, they are facing many difficulties in terms of language, psychology, poverty and many other things. Moreover, many mental health problems have emerged since COVID-19, to which migrant women have been more vulnerable. Alternatively, parks and green spaces have been a key to recovering mental health. In line with this, long-term management of green spaces has been raised as an issue to help promote people's health and empowerment. However, we have little evidence that the issue also conveys the empowerment of migrants and positivity through participation in park and green space management. Therefore, this study aims at 1) understanding migrant women's perception toward participation in park and green space management, 2) analyzing the correlation between empowerment and place-keeping, and 3) deriving implications.Methods: To address the objectives, this study conducts 1) a theoretical review of empowerment and place-keeping of migrant women through literature review and 2) a non-face-to-face survey targeting 108 migrant women. The collected data was analyzed using SPSS 26.Results: The results are as follows: 1) migrant women have highly positive perceptions toward participation in park and green space management, with statistical significance in funding and governance depending on the marital status, and 2) there is a significant correlation between place-keeping and empowerment in role and expression. This means that increasing the role and expression in empowerment can promote more active participation in park and green space management.Conclusion: In conclusion, in order to improve the empowerment of migrant women, they should be guided to actively participate in park and green space management and provided with the opportunity to participate in policy-making.
背景和目标:韩国的移民妇女人数不断增加。然而,他们在语言、心理、贫困和许多其他方面都面临着许多困难。此外,自新冠肺炎以来,出现了许多心理健康问题,移民妇女更容易受到这些问题的影响。另外,公园和绿地也是恢复心理健康的关键。与此相一致,绿地的长期管理已被提为一个问题,以帮助促进人们的健康和赋权。然而,我们几乎没有证据表明,这个问题也通过参与公园和绿地管理来传达移民的赋权和积极性。因此,本研究旨在1)了解移民妇女对参与公园和绿地管理的看法,2)分析赋权与场所管理之间的相关性,以及3)得出启示。方法:为了实现这些目标,本研究进行了1)通过文献综述对移民妇女的赋权和安置进行了理论综述;2)针对108名移民妇女进行了非面对面调查。使用SPSS 26对收集的数据进行分析。结果:结果如下:1)流动妇女对参与公园和绿地管理有高度积极的看法,根据婚姻状况,在资金和治理方面具有统计学意义;2)保留场所与角色和表达方面的赋权之间存在显著相关性。这意味着,增加在赋权中的作用和表达可以促进更积极地参与公园和绿地管理。结论:总之,为了提高移民妇女的权能,应引导她们积极参与公园和绿地管理,并为她们提供参与决策的机会。
