Layout design problem is one of the useful field of study used to increase the efficiency of sources in organizations. In order to achieve an appropriate layout design, it is necessary to define and solve the related nonlinear programming problems. Therefore, using computer in solving the related problems is important in the view of the researchers of this area of study. However, the designs produced by a computer to solve big problems require more time, so, this paper suggests an algorithm that can be useful in better performance of the known algorithms such as Branch and Bound. The proposed study aims to improve the performance of the branch and bound (BB) algorithm in solving QAP problems. The findings show that the proposed method enables the BB algorithm to produce an optimal solution in the minimum amount of time.
布局设计问题是一个有用的研究领域,用于提高资源在组织中的效率。为了实现合理的布局设计,有必要定义和解决相关的非线性规划问题。因此,在这一研究领域的研究者看来,利用计算机来解决相关问题是很重要的。然而,由计算机生成的解决大问题的设计需要更多的时间,因此,本文提出了一种算法,可以更好地性能已知的算法,如分支和边界。本研究旨在提高分支定界(BB)算法在求解QAP问题中的性能。研究结果表明,所提出的方法使BB算法能够在最短的时间内产生最优解。

National Resilience is a nation dynamic condition, and a nation struggle to achieve national goal will be disturbed. National identity, national integration and national life sustainability have stronger than threat, challenge, disturbance and obstacle. This research uses qualitative research method to analyze potential threat, challenge, disturbing and obstacle for Indonesia, which come both from internal and external sources and national resources to face them. In future, potential threat will be dominated by nonmilitary threat. The Indonesia Armed Forces (Tentara Nasional Indonesia), as themain component in Indonesia should face the potential threat. But TNI has its limitations, supporting power is necessary, and one of the potential powers is national resourceswhich or whom converted to reserve component. The role of reserve component in future will contribute to Indonesia national resilience strengthen efforts.
国家韧性是一个国家的动态状态,一个国家在实现国家目标的过程中会受到扰动。国家认同、国家整合和国家生命可持续性比威胁、挑战、干扰和障碍更强。本研究采用定性研究的方法,分析了印尼面临的潜在威胁、挑战、困扰和障碍,这些威胁和挑战既有内外部来源,也有面对这些威胁和挑战的国家资源。未来,潜在威胁将以非军事威胁为主。印度尼西亚武装部队(Tentara Nasional Indonesia)作为印度尼西亚的主要组成部分应该面对潜在的威胁。但TNI也有其局限性,支持力量是必要的,其中一个潜在的力量是国家资源或谁转化为储备成分。储备部分今后的作用将有助于印度尼西亚加强国家恢复力的努力。

Hematological factors may be useful in determining the best physical performance of various game participants. It also indicates the athletes’ health and physical condition. This study deals with the analysis of hematological variables-red blood cells, white blood cells (neutrophil, eosinophil, lymphocytes, monocytes), and platelet among university men basketball, volleyball, and cricket players. Fourteen (14) active players (basketball-5, volleyball-5, and cricket-4) were taken as samples and age range between 20 to 25 years. All players were actively competing at Inter-University levels in their respected sport and they voluntarily participated in this study. Blood samples were collected in the morning session with fasting. Red blood cells, white blood cells, platelet counts were criterion measures in this study. The obtained data were analyzed by one-way ANOVA with the help of SPSS software and the level of signi icance was set at p<0.05. As per the statistical analysis, insigni icant differences were found among the three different game players. In summary, the study found that the red blood cells, white blood cells, and platelet counts are similar in the three groups.

Young Syrian refugees who have experienced the war are in a state of trauma that hinders their normal development, be it physical, emotional, behavioural or even at school level. Geology is, therefore, a dif icult ield to address for both students and teachers. In order to familiarize primary school students (grade 6) with this theme, we have set up and realized a pedagogical project at the ”Janah” educational centre that deals with Syrian refugee students enrolled in public schools in Lebanon. We integrated project-based learning (PBL) into teaching in order to introduce grade 6 students to some basics in geology. Several tests were conducted before and after our intervention. The results show that the PBL develops students’ motivation and involves them more in learning situations while starting from their interests and promoting their cognitive engagement. In addition, PBL promotes their autonomy, awakens their sense of responsibility by integrating them into teams where they collaborate and communicate.
经历过战争的年轻叙利亚难民处于一种创伤状态,阻碍了他们的正常发展,无论是身体、情感、行为,甚至在学校层面。因此,地质学对学生和教师来说都是一个难以解决的领域。为了让小学生(六年级)熟悉这一主题,我们在“Janah”教育中心建立并实施了一个教学项目,该项目涉及在黎巴嫩公立学校就读的叙利亚难民学生。为了向六年级学生介绍一些地质学的基础知识,我们将基于项目的学习(PBL)融入教学中。在我们干预之前和之后进行了几项测试。结果表明,PBL从学生的兴趣出发,促进了学生的认知投入,培养了学生的学习动机,使学生更多地参与到学习情境中。此外,PBL促进了他们的自主性,通过将他们整合到团队中进行协作和沟通,唤醒了他们的责任感。

Background: Fractures of distal end of femur are complex injuries which are difficult to manage. These fractures often are unstable and comminuted. Despite advances in surgical techniques and improvement in implants, treatment of distal femoral fractures remains a challenge in many situations. This study was done to analyse the functional outcome and this management of distal femoral fractures with its complication. Material & Methods: This study has been done between August 2008 to March 2010 on patients coming to Orthopaedics Department at Jawaharlal Nehru Hospital and Research Centre, Bhilai. It is a prospective study which includes 25 patients with 10 Type A, 7 Type B and 8 Type C fractures of distal femur after fulfilling the inclusion and exclusion criteria. Results: Mean age of 47.08 years with sex incidence of 3.17:1(M:F). Mode of injury was RTA in 16, simple fall in 6, fall from height in 2 and railway track accident in 1 patient. There were 5-A1, 1-A2, 4-A3, 3-B1, 1-B2, 3-B3, 1C1, 4-C2 and 3-C3 fractures. Complication in form of varus angulations was found in 5 cases, shortening occurred in 2 patients, backing out of distal femoral locking screw occurred in 1 patient. Deep infection occurred in 1 patient. Implant failure and varus angulations at fracture site occurred in 1 patient. Conclusion: We conclude that minimally invasive surgical techniques and with the availability of locking type of plates distal femoral fractures can now be dealt with more precessions and more satisfactory results can be produced.

Background: Infants who are clinically jaundiced in the first few days are more likely to develop hyperbilirubinemia. Hyperbilirubinemia is the most common medical problem in newborn infants. It is the most important cause for hospital readmissions during the early neonatal period and also the cause for neonatal morbidity. Objective: In this prospective study we are going to evaluate the predictive value of cord bilirubin level for identifying term neonates for subsequent hyperbilirubinemia. Materials and Methods: Cord bilirubin levels at birth and subsequently serum bilirubin levels at 72 h were assessed in 291 neonates. The cutoff value was estimated beyond which there was significant hyperbilirubinemia. Statistics employed include quantitative data which is expressed in terms of mean and SD and qualitative in terms of proportions and receiver operator characteristic curve used to find cut-off value and to find sensitivity and specificity. Results: The cutoff value of cord bilirubin >2 mg/dl had sensitivity and specificity of 77.97 and 56.90%, respectively, with positive predictive value of 31.51 and negative predictive value of 91.03% for subsequent hyperbilirubinemia. Conclusion: To decreases the significant burden of untreated severe neonatal jaundice, cord serum bilirubin can be used as a screening tool to identify the neonatal jaundice in term and this prediction of neonatal hyperbilirubinemia has widespread implication especially in our country where there are limited resources.
背景:在出生最初几天出现临床黄疸的婴儿更有可能发展为高胆红素血症。高胆红素血症是新生儿最常见的医学问题。它是新生儿早期再入院的最重要原因,也是新生儿发病率的主要原因。目的:在这项前瞻性研究中,我们将评估脐带胆红素水平对识别足月新生儿后续高胆红素血症的预测价值。材料和方法:对291例新生儿进行出生时脐带胆红素水平和随后72h血清胆红素水平的评估。估计临界值超过该临界值即存在显著的高胆红素血症。统计学包括定量数据,用均值和标准差表示;定性数据用比例和接收算子特征曲线表示,用来寻找截止值,寻找灵敏度和特异性。结果:脐带胆红素>2 mg/dl临界值对后续高胆红素血症的敏感性和特异性分别为77.97和56.90%,阳性预测值为31.51,阴性预测值为91.03%。结论:脐带血清胆红素可作为早期新生儿黄疸的筛查工具,尤其是在资源有限的我国,对新生儿高胆红素血症的预测具有广泛的意义,以减轻重症新生儿黄疸未经治疗的重大负担。

The Ecotourism Hub: A joint cross-border marketing strategy for peripheral islands 生态旅游中心:周边岛屿的联合跨境营销策略
Pub Date : 2021-06-10 DOI: 10.21463/SHIMA.124
Karl Agius
Notwithstanding their ecotourism potential, small peripheral islands have been closely associated with the enjoyment of sun, sea and sand (3S) as their major tourism product. Fieldwork was conducted in a group of islands/archipelagos collectively known as the Maltese-Sicilian archipelago to identify marketing challenges. Interviews were held with stakeholders to assess their views on the use of a joint cross-border marketing strategy to overcome such challenges. Marketing challenges identified included limited promotion, mostly conducted indirectly, and spearheaded by 3S tourism operators owing to the limited resources of ecotourism operators. Results indicate that several joint marketing and cross- border initiatives are already in place and others are being developed. This approach has the potential to avoid a scenario where small islands are overshadowed by bigger islands and reduces futile competition. By pooling resources, islands will be in a better position to determine their brand, reach more markets and showcase their distinctiveness. Furthermore, products that promote cross-border island hopping increase the competitiveness of small peripheral islands and archipelagos which have experienced habitat fragmentation or islands which are too small to serve as an ecotourism destination on their own.
尽管具有生态旅游潜力,但周边小岛屿与享受阳光、海洋和沙滩(3S)密切相关,这是其主要旅游产品。在一组统称为马耳他-西西里群岛的岛屿/群岛进行了实地调查,以确定营销方面的挑战。与利益攸关方进行了访谈,以评估他们对利用联合跨境营销战略克服这些挑战的看法。确定的营销挑战包括有限的推广,主要是间接进行的,由于生态旅游运营商的资源有限,由3S旅游运营商带头。结果表明,一些联合营销和跨境倡议已经到位,其他倡议正在制定中。这种方法有可能避免小岛屿被大岛屿掩盖的情况,并减少徒劳的竞争。通过整合资源,岛屿可以更好地确定自己的品牌,进入更多的市场,展示自己的独特性。此外,促进跨界跳岛的产品增加了周边小岛屿和群岛的竞争力,这些岛屿和群岛经历了生境破碎或岛屿太小,无法单独作为生态旅游目的地。

Sciatica: Treatment with a Blend of Maitland Mobilization, McKenzie Exercises along with NMES - A Case Study 坐骨神经痛:与Maitland动员,McKenzie练习和NMES混合治疗-一个案例研究
Pub Date : 2021-06-10 DOI: 10.52403/IJRR.20210609

Sciatica is referred to radiculopathy involving any of the lower extremity, caused by either inflammation or compression of the nerve roots L1-S1. It can be diagnosed majorly through an appropriate history taking and physical examinations to not be misdiagnosed with other chronic low back pain conditions. A conservative management is preferred when in an acute stage of 6-8 weeks after which a surgical approached is advised. Although various studies have shown evidences that a prolonged conservative care is most fitting than a short term surgical approach (discectomy). The prevalence of sciatic symptoms ranging from 1.6% to 43%, maximum noted in the working population, has drawn attention for the need of an effective and early conservative care to downsize the symptoms causing discomfort and pain. Thus, the aim of the case report was to present with an early and effective conservative care with a blend of Maitland Mobilization, McKenzie exercises along with Neuro-Muscular Electrical Stimulation (Interferential Current) to minimize the discomfort thus easing and bolstering the individual in activities of daily living followed by an uncomplicated returning back to recreational activities. The patient was managed with a blend of Maitland Mobilization, McKenzie exercises and Interferential current for 7 days consecutively along with an individually tailored Home exercise program according the patient tolerance. Outcomes measures namely numerical pain rating scale, lower extremity functional scale and Roland Morris Disability Questionnaire were evaluated before and after the 7 day intervention period to assess prognosis in pain and pain related disability. Thus the changes in pre and post intervention results stated positive outcomes in reducing pain and improving the functional activity and participation in social and recreational ventures.
坐骨神经痛是指涉及下肢任何部位的神经根病,由炎症或压迫L1-S1神经根引起。主要通过适当的病史记录和体格检查来诊断,以免与其他慢性腰痛疾病误诊。急性期为6-8周,建议行手术治疗时,首选保守治疗。尽管各种研究表明,长期保守治疗比短期手术(椎间盘切除术)更合适。坐骨神经症状的患病率从1.6%到43%不等,在工作人群中最高,这引起了人们对有效和早期保守治疗的关注,以减轻引起不适和疼痛的症状。因此,本病例报告的目的是提供早期有效的保守治疗,结合梅特兰运动、麦肯齐运动和神经肌肉电刺激(干扰电流),以最大限度地减少不适,从而缓解和支持个人的日常生活活动,然后简单地回到娱乐活动中。根据患者的耐受性,对患者进行连续7天的梅特兰运动、麦肯齐运动和干扰电流的混合管理,并进行量身定制的家庭运动计划。在干预期的7天前后分别采用数值疼痛评定量表、下肢功能量表和Roland Morris失能问卷来评估疼痛和疼痛相关失能的预后。因此,干预前和干预后结果的变化表明,在减轻疼痛和改善功能活动以及参与社会和娱乐活动方面取得了积极成果。

MONETARY POLICY IN AN ISLAMIC ECONOMICS 伊斯兰经济学中的货币政策
Pub Date : 2021-06-10 DOI: 10.29121/GRANTHAALAYAH.V9.I5.2021.3948
Bismi Khalidin
The primary aim of this paper is to elucidate the general concept of monetary policy under Islamic Economics. Not only does the stability of but also the growth of the economy in a country strongly depends upon monetary policy implemented. Such the phenomenon also prevails in Islamic Economics in which the term is also ruled by the Holy Quran and the Hadith of the Prophet. Moreover, the Prophet issued some regulations regarding monetary, such as to adopt Dinars and Dirhams as the Islamic currencies. It is noted that, however, the thing distinguishing between Islamic Economics and other economic systems is concerning the variable of interest or usury, where either the Holy Quran or the Hadith clearly states that it is banned. Due to using interest as the yardstick, the conventional monetary instruments such as Open Market Operation, Discount Rate and the likes are not considered as the monetary instruments under Islamic Economics. Therefore, Instead of interest, Islamic Economics adopts Pro it Loss Sharing (PLS) system, regarded as the important part of monetary policy. Moreover, Islamic Economics has also its speci ic monetary standard and instruments, which are far from interest or riba-based variables, such as musharakah certi icates and others.
本文的主要目的是阐明伊斯兰经济学下货币政策的一般概念。一国经济的稳定和增长在很大程度上取决于货币政策的实施。这种现象也普遍存在于伊斯兰经济学中,其中该术语也由神圣的古兰经和先知的圣训统治。此外,先知发布了一些关于货币的规定,例如采用第纳尔和迪拉姆作为伊斯兰货币。然而,值得注意的是,伊斯兰经济学与其他经济体系的区别在于利息或高利贷的变量,《古兰经》或《圣训》都明确指出这是被禁止的。由于以利率为衡量标准,传统的货币工具如公开市场操作、贴现率等不被认为是伊斯兰经济学的货币工具。因此,伊斯兰经济学采用损益分担(PLS)制度来代替利息,并将其作为货币政策的重要组成部分。此外,伊斯兰经济学也有其特定的货币标准和工具,这些标准和工具远非以利息或利息为基础的变量,如穆沙拉夫证书等。
