The movement of animals is one of the primary factors that influence the variation of livestock emissions. This study evaluated the relationship between animal activity and three major emissions, PM₁₀, PM_2.5, and ammonia gas, in weaning, growing, and fattening pig houses through continuous monitoring of the animal activity. The movement score of animals was quantified by the developed image analysis algorithm using 10-second video clips taken in the pig houses. The calculated movement scores were validated by comparison with six activity levels graded by an expert group. A comparison between PMs measurement and the movement scores demonstrated that an increase of the PMs concentrations was obviously followed by increased movement scores, for example, when feeding started. The PM₁₀ concentrations were more affected by the animal activity compared to the PM_2.5 concentrations, which were related to the inflow of external PM_2.5 due to ventilation. The PM₁₀ concentrations in the fattening house were 1.3 times higher than those in the weaning house because of the size of pigs while weaning pigs were more active and moved frequently compared to fattening pigs showing 2.45 times higher movement scores. The results also indicated that indoor ammonia concentration was not significantly influenced by animal activity. This study is significant in the sense that it could provide realistic emission factors of pig farms considering animal's daily activity levels if further monitoring is carried out continuously.

본 글은 어느 특정 동일 집단에 의해 조성된 삼국시대 고분군을 면밀히 분석하여, 고분의 변천과정과 축조집단의 성격을 파악하고자 작성되었다. 울산 약사동 북동유적 삼국시대 목곽묘는 4C 후반에서 6C 초까지 약 150~200년간 지속적으로 조영된 어느 지역 집단의 공동묘역이다. 울산 약사동 북동유적 삼국시대 목곽묘를 분석한 결과, 목곽묘의 규모와 배치관계 그리고 출토유물의 구성 등에서 차이를 보였다. 이러한 특징을 조합하면, 북동유적 목곽묘 축조집단은 총 5개의 계층으로 구분된다. 최상위계층과 상위계층은 목곽의 규모나 매납 유물의 종류와 재질 등으로 볼 때, 목곽묘사회를 이끌어가는 실질적인 지배층, 그리고 중위계층에서 최하계층까지는 대다수를 차지하는 일반민의 신분으로 상정하였다. 그리고 연령(미성인-성인)에 따라 배치관계 및 성격에 있어서 차이를 보였다. 이러한 개인의 신분 및 연령에 따라 사회적(공동체) 기능이나 역할, 성질, 목적 등은 달라지며, 신분이 갖는 의미와 값어치는 사회적 가치와 신념에 따라 결정된다고 볼 수 있다. 한 사회의 구성원들은 공동의 목적과 유대관계를 위해서 계획적이고 조직적인 체계하에서 행동하며, 또한 관습적으로 내려오는 규범(규제) 속에서 조직 자체의 유지 존속을 꾀한다고 볼 수 있다. 그러나 이를 위해서는 조직을 이루고 있는 구성원들 사이의 결합관계가 유기적으로 이루어져야 한다. 이 결합관계는 가장 핵심 요소인 혈연에 기초하여 훨씬 큰 사회공동체 관계를 형성한다고 볼 수 있다.

Background: Since November 2019, long-term care hospitals have been able to provide patients with discharging programs to support the elderly in the community. This study aimed to identify both patient- and hospital-level factors that affect successful community discharge from long-term care hospitals. Methods: A multilevel logistic regression model was performed using hospitals as a clustering unit. The dependent variable was whether a patient stayed in the community for at least 30 days after discharge from a long-term care hospital. As for the patient-level independent variables, an agreement between a patient and the family about discharge, length of hospital stay, patient category, and residence at discharge were included. The number of beds and the ratio of long-stay patients were selected for the hospital-level factors. The sample size was 1,428 patients enrolled in the discharging program from November 2019 to December 2020. Results: The number of patients who were discharged to the community and stayed at least for 30 days was 532 (37.3%). The intraclass correlation coefficient was 22.9%, indicating that hospital-level factors had a significant impact on successful community discharge. The odds ratio (OR) of successful community discharge increased by 1.842 times when the patients and their families agreed on discharge. The ORs also increased by 3.020 or 2.681 times, respectively when the patients planned to discharge to their own house or their child's house compared to those who didn't have a plan for residence at discharge. The ORs increased by 1.922 or 2.250 times when the hospitals were owned by corporate or private property compared to publicly owned hospitals. The ORs decreased by 0.602 or 0.520 times when the hospital was sized over 400 beds or located in small and medium-sized cities compared to less than 200 bedded hospitals or located in metropolitan cities. Conclusion: The results of the study showed that the patients' and their family's willingness for discharge had a great impact on successful community discharge and the hospital-level factors played a significant role in it. Therefore, it is important to acknowledge and support long-term care hospitals to involve active in the patient discharge planning process.

The aim of the present study was to investigate whether Bovine Spongiform Encephalopathy (BSE) is present in this country and to analyze the Global BSE Risk (GBR) status in Bangladesh. A total of 2,000 brain samples were collected from cattle older than 30 months of age, slaughtered for human consumption in the district slaughter houses from 2005 to 2006. The brainstem (obex), Pyriform lobe, cerebrum and cerebellum were subjected to histopathological study. Samples that showed some nonspecific lesions were subjected to immunohistochemistry and only brain stem to ELISA for the detection of abnormal prion protein $PrP^{sc}$. In passive surveillance, annual overall diseases of cattle, buffalo, sheep and goats in Bangladesh were collected from Department of Livestock Services (DLS), Dhaka to investigate the occurrences of neurological diseases. Import related data were collected from "National Export Promotion Bureau" Kawran Bazar, Bangladesh Bank and DLS to analyze the importing products of animal origin (cattle, buffalo, sheep and goats) from different countries to find whether or not the imported products posed any risk for the BSE. In an actire surveillance conducted in slaughter house, histopathologically BSE specific lesions were not detected in any of the brain samples, but other nonspecific lesions were observed. No $PrP^{sc}$ was detected from the samples by immunohistochemistry and ELISA. DLS report also supported the absence of BSE in cattle and buffalo and scrapie in sheep and goats in Bangladesh. It was also clearly recorded that Bangladesh imported livestock products from countries in GBR level I and II but not from countries in GBR level III and IV. From this study it apparently seems that BSE is not currently present in the indigenous animals in Bangladesh and poses no or negligible risk to human and animal health.

Paradigm depending only on fossil fuel for building heat source is rapidly changing. Accelerating the change, as it has been known, is obligation for reducing green house gas coming from use of fossil fuel, i.e. reaction to United Nations Framework Convention on Climate Change. In addition, factors such as high oil price, unstable supply, weapon of petroleum and oil peak, by replacing fossil fuel, contributes to advance of environmental friendly renewable energy which can be continuously reusable. Therefore, current new energy policies, beyond enhancing effectiveness of heat using equipments, are to make best efforts for national competitiveness. Our country supports 11 areas for new renewable energy including sun light, solar heat and wind power. Among those areas, ocean thermal energy specifies tidal power generation using tide of sea, wave and temperature differences, wave power generation and thermal power generation. But heat use of heat source from sea water itself has been excluded as non-utilized energy. In the future, sea water heat source which has not been used so far will be required to be specified as new renewable energy. This research is to survey local heating system in Europe using sea water, central solar heating plants, seasonal thermal energy store and to analyze large scale central solar heating plants in German. Seasonal thermal energy store necessarily need to be equipped with large scale thermal energy store. Currently operating central solar heating system is a effective method which significantly enhances sharing rate of solar heat in a way that stores excessive heat generating in summer and then replenish insufficient heat for winter. Construction cost for this system is primarily dependent on large scale seasonal heat store and this high priced heat store merely plays its role once per year. Since our country is faced with 3 directional sea, active research and development for using sea water heat as cooling and heating heat source is required for seashore villages and building units. This research suggests how to utilize new energy in a way that stores cooling heat of sea water into seasonal thermal energy store when temperature of sea water is its lowest temperature in February based on West Sea and then uses it as cooling heat source when cooling is necessary. Since this method utilizes seasonal thermal energy store from existing central solar heating plant for heating and cooling purpose respectively twice per year maximizing energy efficiency by achieving 2 seasonal thermal energy store, active research and development is necessarily required for the future.

This study is aimed to provide a guide for PC use space in apartment. To achieve this, a design about PC use space which was considered adequate location, area, form was suggested. As methods of the study, survey research method and case study. The survey was taken by five hundred-eighty-nine people who used PCs in apartment from May 2005 to July 2005 in JeJu Special Self-governing Province for an analysis of data. The results of the survey were showed PC use space situation and furnitures layout patterns. The case was classified by unit plans of size, and it showed design example of PC use space. In types of $61{\sim}69$ square meters ($m^2$), PC use space was located in dead-space in the residence with minimum scale, because of $61{\sim}69$ square meters types are smaller than the other types. In types $100{\sim}129$ square meters, PC use space which was divided with a partition panel was located in the livingroom expanding the room space to the balcony. In types of 130 square meters, PC use space was located in the room of sons or daughters which was arranged with other furniture. The adequate area of PC use space is $1.4{\sim}2.2$ square meters, and it should take into account furniture size and human active sphere. And PC use space of form should consider traffic line, personal space and privacy. Besides it is required of ergonomic design in chair, table in its scale. And it is necessary development of systematic furniture for PC use space.
