The rupture of a cerebral arteriovenous malformation is the most common cause of cerebral hemorrhage in children, with recurrence rates reported to be higher than that in adults. Herein, we present the case of a 4-year-old child who initially demonstrated obliteration of a ruptured brain arteriovenous malformation after initial Gamma Knife radiosurgery, but subsequently experienced delayed recurrence, ultimately necessitating a second Gamma Knife radiosurgery procedure. By reviewing this case, we aim to explore considerations regarding the recurrence, treatment, and follow-up strategies for pediatric arteriovenous malformations.

This study investigated and analyzed the factors influencing the preference of MZ generation real estate assets. First, preference was confirmed by comparing real estate assets and financial assets, and then detailed preferred assets in real estate assets were examined. In addition, it was divided into the entire MZ generation, M generation, and Z generation to examine which assets each group prefers.
Acording According to the analysis results, it was confirmed that the preferred assets of the MZ generation were different by period. At this point, it has been confirmed that financial assets are preferred to raise a large amount of money, but real estate assets are preferred at the future point. Among real estate assets, apartments were the most preferred. In addition, it was found that there are differences in asset preference influencing factors between Generation M and Generation Z.
The results of this study will also serve as investment product marketing data for asset market suppliers and can be used as future asset market guidelines for consumers.

The seriousness of the domestic fisheries industry has fundamental problems, starting mainly due to the depletion of fishery resources, the aging of fishing workers, and the aging of fishing boats and equipment, and the production of coastal fishing (capturing and fishing methods) continues to decline every year due to problems such as illegal overfishing, global warming, and environmental pollution. Despite this situation, global seafood consumption is increasing and the per capita meat consumption is approaching. To this end, a continuous and stable supply system can be established only by further expanding the smart management system that further develops the existing aquaculture industry (farm culture) beyond the traditional fishing method and innovatively improves the inland aquaculture on land. As a result, smart farming will be able to quickly recognize changes in aquaculture conditions, water temperature, and water quality by utilizing artificial intelligence (AI), big data technology, information and communication technology (ICT), and the Internet of Things (IoT), respond to the situation, and engage in stable aquaculture.

As of the end of 2020, Korea has entered a full-scale population decline in which the country's total population is declining due to the dead-cross phenomenon, which is the highest in history, with more deaths than births. The government is actively promoting population decline response policies and designating 89 population decline areas. It is necessary to promote efficient projects according to the characteristics of population decline regions. Therefore, this paper conducted a cluster analysis by selecting indicators based on the population decline index, which was the basis for the designation of population decline areas, and completed a regional characteristic analysis for 89 areas selected by the local government based on the population decline index and categorized them into three clusters to analyze the characteristics of each cluster and suggest policy response directions. Cluster 1 showed that policies to prevent the departure of declining businesses in the area, the supply of new housing, and the provision of welfare facilities for the elderly were required. Cluster 2 required settlement support policies for the settlement of the daytime population, the creation of welfare facilities for the elderly and vulnerable, and support policies for the stable settlement of businesses. Cluster 3 explored policies for the welfare of the elderly, the supply of new housing, the maintenance of vacant houses, the expansion of local finances, and the support of urban-to-rural Migration. These results can be used as a basis for establishing a policy direction for responding to population decline that considers the differences in regional characteristics of population decline areas.

Objective: We analyzed the clinical outcomes of Meckel’s cave compression with Teflon (Rhee’s method) as a new modified and additional surgical technique for trigeminal neuralgia (TN).Methods: Between March 1996 and December 2014, out of 78 patients who were treated with microvascular decompression (MVD) or partial sensory root rhizotomy, 28 patients additionally underwent Meckel’s cave compression with Teflon. The mean age at initial treatment was 54.3 years (range: 40–69 years). The mean duration from onset to operation was 70.5 months (range: 5–360 months) and the mean follow-up period was 26 months (range: 1–77 months). Results: Fifteen patients (53.6%) had facial pain in the V2/V3 distribution. The offending or associating vessel was the superior cerebellar artery in four patients (14.3%), the superior petrosal vein in six (21.4%), the anterior inferior cerebellar artery in two (7.1%), multiple vessels in nine (32.1%), and miscellaneous arteries or veins in six (21.4%). One patient (3.6%) had no offending vessel, and seven patients were had no definite offending vessels that contacted the trigeminal root entry zone. Meckel’s cave compression with Teflon was applied to all patients: 10 (35.7%) in combination with MVD, one (3.6%) with partial rhizotomy, and 17 (60.7%) with both MVD and partial rhizotomy. TN was relieved in 26 patients (92.9%) and symptoms recurred in three patients (pain-free rate: 82.1%). The complication rate of this method appeared to be similar to other treatment procedures. Conclusion: Meckel’s cave compression with Teflon may be a safe and useful additional treatment procedure for TN.

In Korea, the market environment has changed rapidly due to low birth rate and aging population.
Accordingly, there was a need for change in housing welfare policies centered on the homeless and low-income class. In Korea, with the announcement of the Housing Welfare Roadmap in 2017, housing welfare policies according to the life cycle are being pursued in earnest. Therefore, there is a need to evaluate satisfaction with housing welfare services and analyze influencing factors. In this study, based on a housing survey, awareness and satisfaction with housing welfare services were evaluated by generation according to the life cycle and influential factors were analyzed.
The results of the analysis showed that, except for loan services and housing supply, awareness of housing welfare services was low. In terms of satisfaction with housing welfare services, the overall level was found to be good. In the analysis of variance by generation for the evaluation of housing welfare services, significant differences in averages by generation were found. In an analysis of factors affecting satisfaction with housing welfare services, it was found that satisfaction was low when the household was headed by a female and the household size was small. As the area of the house increases, satisfaction with lease and purchase financing appears to decrease, but satisfaction with public housing appears to increase.
Considering these analysis results, it is necessary to actively promote housing welfare services according to the life cycle and continuously promote the development of differentiated welfare services by generation.

If a home tenant does not receive a deposit back after the contract is terminated, a lease deposit return guarantee system is in effect to protect it, but there are still many aspects to be improved. In this study, we would like to present the direction of improvement of the lease deposit return guarantee system as follows.
First, when a tenant applies for guarantee insurance, there is still a lot of time delay. In the future, if the tenant applies for a lease registration order, and if the tenant applies for guarantee insurance, the guarantee agency must check only the necessary matters such as the house's brightness and payment in advance.
Second, in signing up for guarantee insurance, the limitation of the deposit should be deleted so that all tenants can use this system if necessary.
Third, if there is a change in the size and target of application to improve the system, it should be applied only to new leases, and the previous matters should be applied to renewed leases. This is because if it is also applied to renewed leases, there may be many cases in which guarantee insurance cannot be subscribed while being renewed.

Objective This nationwide longitudinal follow-up study investigated the relationship between ischemic stroke and ossification of the posterior longitudinal ligament (OPLL). Methods Patient data were gathered from the National Health Insurance Service Health Screening cohort. Patients with OPLL were identified by the International Classification of Diseases, 10th revision codes M48.8, M48.81, M48.82, and M48.83. Age- and sex- stratified matching at a 1:5 ratio was used to include a total of 1,289 patients with OPLL and 6,445 controls from January 1, 2004 to July 31, 2015. The Kaplan-Meier method was used to calculate the ischemic stroke incidence rate for each group. Cox proportional-hazards regression analysis was used to estimate the hazard ratio of ischemic stroke. Results Ischemic stroke occurred in 92 (7.1%) patients in the OPLL group and 162 (2.5%) patients in the control group had ischemic stroke. Adjusting for age and sex, the hazard ratio of ischemic stroke in the OPLL group was 4.692 (95% confidence interval [CI], 3.610-6.099). The hazard ratio of ischemic stroke in the OPLL group was 5.008 (95% CI, 3.845-6.516) when considering additional income and underlying diseases. The subgroup analysis showed higher risk ratios of ischemic stroke in all OPLL patient subgroups defined in terms of sex, age, diabetes, hypertension, and dyslipidemia. Conclusion The incidence rate of ischemic stroke was elevated in patients with OPLL according to this nationwide longitudinal study.
