Purpose: This study aims to substantiate a correlation between the period of living alone in a shabby one-room and a depression experience. Methods: We conducted a cross-sectional study using data from the Korea Homeless Survey carried out by the Korea Institute for Health and Social Affairs in 2016. In the study, the data included 485 survey participants who resided in a single room. The period of single-room occupancy being divided into three groups: less than 1 year, 1 to 4 years, and more than 5 years was considered a primary independent variable. The outcome variable which represented a depression experience was measured by CESD-11(The Center for Epidemiological Studies-Depression Scale). We carried out a Chi-square test and multiple logistic regression to evaluate the association. Results: The rate of depression experienced in this population was 77.5%. Almost 83.9% of the participants were reported as being unable to receive the mental health counselling in the last 12 months. After controlling for covariates, subjects who were living in a single room occupancy for 1-5 years(OR=3.89; 95% CI=1.43-10.56) and more than 5 years(OR=2.71; 95% CI= 1.05-6.95) were found to be more likely to experience depression. Conclusions: The results showed that living alone in a shabby one-room had a high correlation with experiencing depression. We proposed that there is a need to develop a new strategy for mental health promotion program for the poor, vulnerable and deprived population.

Currently, there are a total of 68 emergency rooms based on Seoul, South Korea, and there is a portal site that allows you to inquire the location of the emergency room, but it is difficult to use in an actual emergency situation because it consists of selecting a gu and a self-governing dong. In addition, it may be more efficient to go to the emergency room directly because you may miss the golden time necessary for survival in a situation where you call 119 and wait for the rescue team. Therefore, in this paper, we propose a service that can quickly search the location of the emergency room based on a specific location through various functions supported by MongoDB. After downloading emergency room location data based on Seoul Metropolitan City, storing it in MongoDB, processing the data through various processing techniques, and applying a spatial index, you can query the emergency room based on distance from a specific location in real time.

Secondary batteries used in electric vehicles have a potential risk of ignition and explosion. Various safety measures are being taken to prevent these risks. A numerical study was performed using a computational fluid dynamics code on the cases where pressure relief vents that can reduce the blast overpressures of batteries were installed in the through-compression test room, short-circuit drop test room, combustion test room, and immersion test room in facilities rleated to battery used in electric vehicles. This study was conducted using the weight of TNT equivalent to the energy release from the battery, where the the thermal runaway energy was set to 324,000 kJ for the capacity of the lithium-ion battery was 90 kWh and the state of charge (SOC) of the battery of 100%. The explosion energy of TNT (△H_TNT) generally has a range of 4,437 to 4,765 kJ/kg, and a value of 4,500 kJ/kg was thus used in this study. The dimensionless explosion efficiency coefficient was defined as 15% assuming the most unfavorable condition, and the TNT equivalent mass was calculated to be 11 kg. The internal explosion generated in a test room shows the very complex propagation behavior of blast waves. The shock wave generated after the explosion creates reflected shock waves on all inner surfaces. If the internally reflected shock waves are not effectively released to the outside, the overpressures inside are increased or maintained due to the continuous reflection and superposition from the inside for a long time. Blast simulations for internal explosion targeting four test rooms with pressure relief vents installed were herein conducted. It was found that that the maximum blast overpressure of 34.69 bar occurred on the rear wall of the immersion test room, and the smallest blast overpressure was calculated to be 3.58 bar on the side wall of the short-circuit drop test room.

Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from "A Study for Standard Triage Design and Construction Document" but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.

In this paper, the information education plan of the Ministry of Education and offices of education was analyzed in relation to the construction of the AI convergence education room. And based on this, an appropriate construction direction was suggested. For research, AI convergence education room construction plan, budget amount per school and etc were analyzed in the information education plan of the Ministry of Education, KERIS, KOFAC, and the plan of leading schools for AI education. Although the Ministry of Education is making various efforts to promote SW education and artificial intelligence convergence education, it is found that the number is far insufficient compared to the number of elementary, middle and high schools. Efforts to expand the information education room at the government level are continuously required, and in order to utilize the developed artificial intelligence convergence education room, it is necessary to provide abundant teaching and learning examples for the construction space model. In addition, school-level planning and execution must be followed so that the constructed space can be used appropriately, and management and maintenance plans for equipment are required.

The aim of this study was to evaluate the effects of a mother-child shared room on self-confidence in infant care and the practice of breastfeeding by delivering individual education to the mother-child in the shared room. The participants were 50 mothers in the mother-child shared room group and 50 mothers in the mother-child in separate rooms group, all of whom delivered children. The self-confidence in infant care was found to be higher in the mother-child shared room group than the mother-child in separate rooms group. It is necessary to conduct multilateral research into the influential factors on the practice of breastfeeding apart from a variable, namely, the mother-child shared room.

The purpose of this study is to examine the effect of supportive nursing intervention on patient's response of anxiety in emergency room as the suspected experimental research sequentially designed for the unequal control group. This study collected the data from 100 patients including 50 patients of experimental group and 50 patients of control group in emergency room of the only one university hospital from July 12. to September 30, 1999. This study used questionnaires that Kim, Jung Taek and Shin. Dong Kyun revised the measurement of STAI(State-Trait Anxiety Inventory) of Spielberger(1972) to measure their anxiety with using physical. spiritual. and informative support of the supportive nursing intervention, and measured blood pressure. pulse and respiration by physiological response of anxiety. After then. this study analyzed the frequency and percentage by using SPSS 7.5 program, $x^2-test$, t-test and ANCOVA. The results are as follows: First hypothesis : the point of STAI of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F=22.943, p=.000). Second hypothesis : the sistolic blood pressure of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F=42.603. p=.000). Third hypothesis. the diastolic blood pressure of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention(F= 18.482, p=.000). Fourth hypothesis: the pulse of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention. Fifth hypothesis : The respiration of experimental group who received the supportive nursing intervention during emergency room staying will be lower than that of control group without the supportive nursing intervention. In the above-mentioned result. the supportive nursing intervention was considered to be useful intervention that raised the effect on patient's response of anxiety during emergency room staying.

In this study, in order to evaluate stability of the room-and-pillar underground structure, a series of preliminary numerical analyses were performed. Design concept and procedure of an underground structure for obtaining a space are proposed, which should be different from structural design for the room-and-pillar in mine. With assumed material properties, a series of numerical analyses were performed by varying size ratios of room and pillar and then the failure modes and location at yielding initiation were investigated. From the results, relationship between the ratio of pillar width to the roof span (w/s) and overburden pressure at failure initiation shows a relatively linear relation, and the effect of w/s on structural stability is much more critical than the ratio of pillar width and height (w/H) which is a crucial parameter in design of the room-and-pillar mining. It means that roof tensile failure and shear failure at shoulder and pillar are necessary to be considered together for confirming overall structural stability of the room-and-pillar structure, rather than considering the pillar stability only in mining. Failure modes and location at failure initiation were varied with respect to the ratio of room and pillar widths. Therefore, it is necessary to simultaneously consider stability of both roof span and pillar for design of underground structure by the room-and-pillar method.

This is the study to the effect that the problems of the protective institution where the whole health of school is performed should be solved for the purpose of much more effective school business after investigating the situations of the management about health system in the elementary school of seoul city The subjects of the research are five students of the school which practices health class in the protective institution, five students of the school which puts health class to practice in each classroom and five nursing teachers who work for each elementary school Its data resulted from that from July to September 1997, I visited five schools in person at Kang nam ku, Dong chak ku, Yong san ku, Kwan ak ku, Kang dong ku and then I met and talked with the nursing teacher and the children Through this inspection and interpretation, I could figure out such things as follows. 1 The structure of the nursing room is so small that it has quite a few things inconvenient for the children and the nursing teacher to use together So for the sake of the health in school, first of all, Its size has to be larger 2. The name as the protective institution has to be changed into the health room. And the room for rest cure, dressing room, counselling room and the room for the health education should be equipped with the inside of health room 3 The nursing teacher as a health teacher has to carry out the health class at a health room. 4 It was required that the principal and the Ministry of Education should be highly interested in the health of school In particular, the advice for instructing expert agents about the health and the cooperation of the principal was urgently demanded. Through the result above, the health of school will be accomplished not only in first-aid treat and injection but also in the education about health as a main duty And the nursing teacher also can play a role as a teacher for health fully The programming, practice and estimation of the health room of the business for health in school will be feedback.
