Objectives : This study was performed to examine medical care utilization of psychiatric patients and to explore patients' characteristics associated with extended hospitalization. Methods : Data were extracted from information of Korean Health Insurance Review and Assessment Service. All data associated with admission and outpatient clinic visit were analysed by patient characteristics. We selected first psychiatric admission patients who diagnosed mental and behavioral disorders due to use of alcohol (main disease code: F10), schizophrenia and related disorders (F20-29) and mood disorders (F30~33) from January to June 2005. We analysed status of admission, mean length of stay, regular access to outpatient clinic and rates of extended hospitalization during 3 years. Bivariate and multivariate analyses were conducted to identify factors associated with extended hospitalization. Results : The number of psychiatric patients during the first six month of 2005 was 30,678. The mean length of stay was longest for schizophrenia and related disorders but shortest for mood disorders. Patients who experienced an extended hospitalization were 18.8% of total subjects. An extended hospitalization was more common in schizophrenia and related disorders than other diagnostic groups. The factors associated with the extended hospitalization were age, sex, diagnostic group, type of insurance and medical care utilization groups. Conclusions : The study indicates the problem of an extended hospitalization for psychiatric patients in Korea. It is suggested that variations in rates of extended hospitalization among medical care utilization group may need an active early intervention system in psychiatric treatment service. Particular attention needs to be devoted to planning and funding for reducing extended hospitalization.

The current status of Korean hospitals on foodservice hygiene was evaluated by a survey in the March of 2000 from 96 hospitals in terms of general sanitation management, education and training, and from 35 hospitals on the observance of hygienic practices in the whole stages of foodservice, personal hygiene, and kitchen equipment and facility hygiene. The questionnaire was filled directly by the dietitian working in the subject hospital. The status of general sanitation management was satisfactory overall; however, the record-keeping or documentation of the practices was the weak point which needs to be improved. only 4% of the subjects appeared to have implemented HACCP for the hospital foodservice. Comparison of the hospitals in their observance rate of hygienic practice by the type of hospital, the location of hospital, the number of bed, and the separation of dietitian's duties as clinical nutrition and foodservice showed characteristic trends among the groups. General hospitals often showed better scores than tertiary hospitals in their observance rates. As the location of hospital moved from large cities to small towns, the observance rate for hygienic practice decreased. Hospitals with entrusted foodservice system showed better scores in hygienic practice than those with owner-operated one in the stage of planning and equipment/facility hygiene (p＜0.05). And the scores of the hospitals having dietitian's duties separated into clinical and food services were higher than the ones with un-separated duties. Detailed information obtained in this study would serve for the development of guidelines or programs to improve the hygienic level of Korean hospital foodservice.

가뭄은 장기간에 걸쳐 기상, 수문, 유역조건 등 복잡하고 다양한 요소에 의해 영향을 받아 진행되므로 사전에 인지하고 판단하는 것은 매우 어렵다. 또한, 일단 가뭄이 진행되면 사회 경제적으로 피해가 막대하게 발생할 수 있기 때문에 가뭄이 발생하기 전 효율적으로 모니터링하고 사전에 대응하는 것이 무엇보다도 중요하다. 이러한 가뭄의 피해를 최소화하기 위해 미국에서는 20년 전부터 가뭄감시 및 조기경보를 통한 선제적 가뭄대응 체계를 구축하여 운영 중이지만 우리나라는 그간 '사후피해 최소화' 위주의 정책으로 가뭄에 대응해 왔다. 지난해 우리나라를 포함한 전 세계는 역사상 유례없는 강수량 부족에 따른 가뭄으로 많은 어려움을 겪었다. 이에 따라, 정부는 보다 현실성 있는 가뭄분석과 대응을 목적으로 지난해 11월 국가정책조정회의를 통해 '선제적 가뭄대응'을 위한 가뭄정보분석센터(이하 센터)를 K-water에 신설하였다. 그간 우리나라는 기상청에서 가뭄을 판단하고 예측하기 위해 강수량 또는 토양수분량 등을 활용하는 '가뭄지수'를 통해 가뭄에 대한 정보를 일부 제공해 왔다. 하지만 국민들은 생 공용수 부족 시 가뭄을 체감하게 되므로 '가뭄지수'에 근거한 가뭄 판단으로는 국민이 체감하는 가뭄을 제대로 표현하지 못하는 한계가 있었다. 따라서 '가뭄지수'에 근거한 가뭄 판단으로는 초기 가뭄대응 시 국민적 공감을 얻지 못할 뿐만 아니라 효율적으로 가뭄에 대응하지 못하는 결과까지 초래될 수 있어 우리나라 실정에 맞는 가뭄판단기준과 전망기준마련이 무엇보다 시급하다고 할 수 있다. 센터는 이러한 기존 '가뭄지수'가 갖는 한계를 극복하기 위해 생 공용수의 수급 불균형을 고려하여 우리나라 실정에 맞는 수원별 가뭄판단기준과 전망기준을 마련하였으며, 이를 기반으로 1월에는 충청 및 수도권 지역에 대한 가뭄정보분석시스템을 구축하였고, 3월부터는 전국단위로 확대해 가뭄 예 경보를 시범운영 중에 있다. 또한 센터는 1년동안 시범운영 기간을 거친 후 내년부터는 본격적인 대국민 가뭄 모니터링 및 전망 정보서비스를 제공할 예정이다. 향후에는 위성정보를 활용한 가뭄영향 평가와 가뭄에 따른 물환경 영향 평가 등으로 영역을 확장하여 가뭄 통합정보를 제공하고, 사회적 경제적 영향이 고려된 가뭄평가뿐만 아니라 물리적 기반의 정량적 예측을 지속적으로 추진하여 기후변화에 대응하고 국민과 함께 가뭄문제를 효과적 해결할 수 있도록 노력해 나갈 예정이다.

A fixed reflectivity-rainfall relationship approach, such as the Marshall-Palmer relationship, for an entire year and different seasons, can be problematic in cases where the relationship varies spatially and temporally throughout a region. From this perspective, this study explores the use of long-term radar reflectivity for South Korea to obtain a nationwide calibrated Z-R relationship and the associated uncertainties within a Bayesian inference framework. A calibrated spatially structured pattern in the parameters exists, particularly for the wet season and parameter for the dry season. A pronounced region of high values during the wet and dry seasons may be partially associated with storm movements in that season. Overall, the radar rainfall fields based on the proposed modeling procedure are similar to the observed rainfall fields. In contrast, the radar rainfall fields obtained from the existing Marshall-Palmer relationship show a systematic underestimation. In the event of high impact weather, it is expected that the value of national radar resources can be improved by establishing an active watershed-level hydrological analysis system.

This study aims to analyze the changes in school/corporate authorities participation after overseas training in Germany and Switzerland. According to this study, the satisfaction with program contents and help for the operation of apprenticeship education was very high. Even though the satisfaction with each type of apprenticeship education institutes did not show differences in accordance with participants' age, there were statistically significant differences in the satisfaction in accordance with work area and position, so that it would be necessary to reflect the results of analysis on the selection of institutes to visit in the future. Regarding the changes in the perception of operation of apprenticeship school in accordance with school/corporate authorities' participation in overseas training, school authorities' perception of the whole areas was improved after training than before training like understanding, planning, practice, and evaluation of apprenticeship education while corporate authorities' perception was not. As corporate authorities also understood the necessity of overseas training for the operation of apprenticeship education, however, in order to increase the effects of overseas training in the future, it would be necessary to provide lots of information to help the understanding of apprenticeship education through preliminary training or regular council and council of each project group. Because of the huge differences in socio-cultural conditions in the practice of apprenticeship education between Korea and two countries such as Germany and Switzerland, it would be needed to operate overseas training that could draw the improvement measures within the system of Korea instead of simple comparative analysis.

Smart phone based navigation applications are very useful in everyday life. Cost-effective and user friendly navigation can be provided to the user by many applications available in market. Using the Smart phone these navigation applications provide accurate navigation for outdoor locations. But providing an accurate navigation underground space such as subway station is still a challenge. It is hence more convenient and appropriate for mobility services if the visitors could simply view the guidance of the subway station on their mobile phone, wherever and whenever it is needed. This study develops a algorithm for indoor navigation with the help of Augmented Reality(AR) and QR marker code from the entrance to the train platform for users. This indoor navigation uses AR and QR maker codes for two purposes: to provide the user link to the subway station location and to provide the current guidance details to the user. This Smart phone algorithm that uses a smart phone optical tool to decode the QR marker to determine the location information and provide guidance to the AR without indoor Maps. This algorithm also provides a module to guide mobility vulnerable to the Barrier Free route to destination.

Electrical energy is an essential component in present societies, which is an important basis for our technological society. In the design of new power infrastructure, it is important to consider the psychological aspects of how our culture considers and aspects its development as an integral component of the community environment. The construction of new high voltage overhead transmission lines has become a controversial issue for public policy of government due to social opposition. The members of community are concerned about how these power lines may have an impact on their lives, basically caused by their effects on health and safety. The landscape and visual impact is one of the most impact that can be easily perceived for local community. The computer 3D simulation of new landscape is illustrated by a real life use corresponding to the selection of the power line route with least observability for local community. This paper used ArcGIS(geographic information system tool) for planning, survey, basic route and detailed route, route for implementation of transmission line corridor. Also, the paper showed the map of natural environment, living environment, safety and altitude using database of power line corridor, and transmission siting model was developed by this study. The suggested landscape of computer simulation with lowest visibility on a power line zone can contribute to reducing oppositions of local community and accelerating the construction of new power lines.

Officially assessed land price has been the index of South Korea since 1989 throughout different sectors of tax and welfare. Officially assessed land price is used as a tax valuation for the tax on property holdings, and the equity of such is the most important factor in the fair taxation for the people of South Korea. On this wise, this research analyzed and verified the horizontal and vertical inequity of officially assessed land price in Seoul by using the real transaction data between 2016 and 2018. In fact, Seoul's assessment ratio for the entire three-year period was 60.64% and it showed to increase each year. Horizontal equity was found to be most favorable in 2017, and the horizontal equity of each borough of Seoul appeared to improve each year. Vertical inequity was found to have reverse inequality in most boroughs of Seoul, however, some parts of Gangnam districts such as Gangnam-gu, Seocho-gu, and Gangdong-gu presented progressive inequality. Such example showed the need for improvement in terms of balance by each borough. The use of quantile regression demonstrated reverse inequality in most quantile, but, the differences in the value of the coefficient by each quantile showed the need for improvement of officially assessed land price with the equity of each quantile. Through the equity verification of officially assessed land price, it was analyzed that the lack of equity was found by year, by borough, and by use district. In order to redeem the lack of equity, the government must systematically supplement the real-estate disclosure system by initiating ratio studies to verify horizontal and vertical equity.

Purpose: This study presents the analysis on space usage of delivery departments in regional public hospitals. The results intention is to achieve improvement of the delivery environment for the mothers and newborns regarding exposure prevention and efficient infection control. The purpose of this study is to provide fundamental data for architectural plans and guidelines for the delivery department. Method: The investigation and analysis were based on research papers, legal systems, public medical statistical data, and the architectural floor plan drawing. For research, 20 regional public hospitals with an operating delivery room were excluded. Regarding data accessibility, 15 regional public hospitals were selected. Results: To overcome the increased vulnerability of the delivery department, the research results of basic data is provided for the establishment to address urgent needs and rapid response. Thus, the research results are as follows: Firstly, the delivery department needs to respond promptly according to the type of patients. For example, in a case of emergency surgery, a connected circulation plan with the related departments is needed. Secondly, for the environment of the delivery area, alleviating anxiety is imperative for pregnant patients and guardians, labor, childbirth, and recovery. Therefore, these needs must be addressed for treatment space and circulation. Lastly, the delivery department is classified into three areas for analysis: access area, treatment area, and support area. In most of the delivery departments of the 15 selected hospitals, there is no space for the access and support area except for the labor and delivery rooms in the treatment area. For the access area, a waiting area, changing room for pregnant women and guardians, and a storage space for contaminated linens are required for infection prevention, safety, and efficiency. For the treatment area, childbirth processes and circulation should have space reserved for labor, delivery, recovery, examination, and treatment. In preparation for an emergency during childbirth, emergency response measures and supporting space needs to be established. For the support area, circulation and rooms are to be designed for medical staff support, activity space, storage and transportation of equipment, and urgent medical treatment. Implications: Along with the low fertility rate and the decrease of medical institutions that operate delivery departments, for the purpose of establishing a public medical service system and a healthy medical environment for mothers and newborns, the researched information demonstrates basic data on space plan of delivery departments in regional public hospitals.

This study targeted KakaoTalk app users, mainly in Seoul and the metropolitan area, and verified the factors that had a significant impact on the intention to continuously use the app through KakaoTalk contents. Among various content characteristics, five variables were used to verify the variables that had the greatest influence on the intention to continue using, and the ones that did not. As a result of testing the five hypotheses, it was found that convenience, enjoyment, informativeness, and perceived usefulness had a significant positive(+) effect on the intention to continue using, but intimacy did not. From this, it can be determined that the majority of users use the app content because it is useful and informative, rather than because they have a sense of familiarity. In this way, the purpose of this study is to provide empirical help to factors closely related to the intention of continuous use in deriving priorities to be considered in the service planning stage as well as in terms of technical design of contents when developing mobile apps in the mobile app industry as a whole and in the field in the future. I want to provide it, but there is a meaning.
