The increasing rate of obesity in school aged children has become a conspicuous social phenomenon in Korea. This has been linked to greater economic growth, increasingly westernized dietary habits, and a consumer driven society. Given that obesity can lead to social exclusion or unfavorable attention by other students in a school setting, the design of plus-size garments have become important for effective appearance management skills. This research aimed to establish a somatotype database for obese school boys, aged 10 to 12, in order to develop a sizing system for plus-size upper garments. In order to measure somatotype of average and obese school boys, five categories were recorded; height, obesity, length of trunk, thickness of neck and chest. For obese boys, subcutaneous fat thickness and position of B.P/shoulder point factors were recorded. Obesity factor was subdivided into overall and specific ones, and while the deviation of obese body types was severe compared to the average type. Obese body type showed significantly higher measurements in width, girth, thickness. This is linked to the fact that the frequency ratio of obesity increases with age. Stature and chest were chosen as control dimensions for boys' wear. As crosstabulation of stature(5cm interval) and chest girth(2, 3 and 4cm), and stature(5cm interval)/chest girth(3cm interval) sizing system showed, the most effective cover ratio and adaptability to the data distribution $25{\sim}75$ quartile. Based on the findings, 10 sizes were formulated for average body type, while 18 sizes were formulated for obese type, whose size cover ratios were 48% and 62.9%, respectively. The primary ranges of stature were $145cm{\sim}150cm$, while those of chest girth were $79{\sim}82cm$. Each size was declared as "chest-somatotype{A(average)/O(obesity)-stature". This study proposed a plus-size upper garment sizing systems for obese boys, accompanied with reference measurements for suit, casual wear and underwear. The finding showed that the two systems were totally separate and not overlapping, meaning that plus-size sizing system is essential for obese school boys. The obesity type system had more size and wider range specs.

야생동물의 신체부위의 절단은 야생에서 활동에 영향을 미칠 수 있으며, 특히 겨울철 동면기간에 새끼를 출산하는 반달가슴곰의 경우 겨울철 생존과 양육활동에 영향을 미칠 수 있다. 지난 2017년 지리산국립공원에 서식하는 반달가슴곰이 올무에 걸려 오른쪽 앞발 절단 수술을 하여 같은 해에 야생에 방사되어 2개체의 새끼를 출산하였다. 이 개체와 함께 같은 해에 출산한 암컷 5마리의 출산 및 양육기간 동안 계절별로 행동권을 분석한 결과, 활동 시기에는 다른 개체들에 비해 넓은 행동권과 많은 이동거리를 나타냈다. 이는 신체장애로 인한 먹이 활동과 새끼 양육에 따른 영향으로 추정된다. 다른 개체들에 비해 불리한 환경에서 자라난 반달가슴곰 새끼가 현재는 문제를 일으키지 않지만 지속적인 모니터링을 통해서 어미의 양육 학습의 성공여부를 파악할 수 있을 것이다. 이 연구결과는 여러 관점에서의 사람과의 갈등에 대한 장기적인 관리 방향을 설정하고 계획을 수립하는 데 활용될 수 있을 것이라 판단된다.

본 연구는 두루미(Grus japonensis)의 이용분포 내에서 행동권 분석의 기법인 MCP(최소볼록다각형법), KDE(커널밀도측정법), LoCoH(국지근린지점외곽연결)를 이용하여 이용면적과 핵심서식지를 선정하였다. 또한, 각 기법의 차이와 의미를 고찰하도록 하였다. 두루미의 분포자료는 철원지역 2012년 2월 17일 조사자료를 사용하였다. MCP에 의한 두루미류 서식영역은 $140km^2$이었다. KDE 분석에서 띠폭에 해당하는 h값을 1000m, CVh, LSCVh로 달리하여 KDE 등치선을 생성하였을 때, 핵심지역에 해당하는(Kernel 50% 이상) 면적은 $33.3km^2$($KDE_{1000m}$), $25.7km^2$($KDE_{CVh}$), $19.7km^2$($KDE_{LSCVh}$)이었다. 결과적으로 띠폭에 대한 기본값(1000m)-CVh(554.6m)-LSCVh(329.9m) 순으로 변수를 작게 입력할 경우 핵심면적 개수는 늘어나고, 면적은 감소하였으며, 형태의 복잡성은 증가하였다. 두루미류의 KDE 분석에 의한 핵심지역의 선정에서 적합한 띠폭변수는 CVh 값인 것으로 판단되었다. LoCoH분석에서는 서식범위와 핵심지역(50% 등치선 이상의 지역)의 면적이 k값의 증가에 따라 증가하는 모습을 보였으며, 점차 큰 핵심지역으로 합쳐지는 모습을 나타내었다. 핵심지역을 도출하기에 적합한 k 값은 24로 나타났으며, 전체 개체군의 핵심지역은 $18.2km^2$로 전체 서식면적의 16.5%를 차지하였다. 최종적으로, LoCoH 분석은 두 개의 큰 핵심서식지를 제시하였으며, 이것은 KDE에 의한 핵심지역에 비하여 작은 수의 핵심지역을 제시한 것이었다. 국내의 게재논문 및 발표자료를 포함한 연구에서 KDE는 대부분 기본설정으로 분석되었으며, 띠폭에 의한 변수를 고려한 것은 매우 드물었다. 따라서 띠폭변수를 명확히 제시하는 것이 요구되었다.

This study was carried out to obtain basic data required to plan and develop Rehabilitation Day Care Program for the stroke Survivors at home in Korea. The subjects comprised of 118 stroke survivors who discharged from 4 hospitals in Seoul during the past 2 years. The data were collected from August 3, 1998 to September 18, 1998, through interviews with questionnaires about general characteristics, activities of dally living, depression and service need of rehabilitation day care program at the outpatient clinics by trained nursing graduates. Data were analyzed with descriptive analysis, Pearson's correlation analysis, and Stepwise multiple linear regression analysis using SPSS/WIN program. The results obtained are as follows ; 1. The mean score of the general need of rehabilitation day care program of stroke survivors was 2.78(range 1-4). The highest need among the service categories of the rehabilitation day care program was self-care and restorative activities category, and health services referral category, recreation category, psychosocial activities category in order. The needs of each category are as follows ; 1) In the health services referral category, the need for speech therapy was highest, followed by the need for physical therapy and occupational therapy. 2) In the psychosocial activities category, the need for self-help group was highest. 3) In the self-care and restorative activities category, the need for bathing was highest, followed by bowel training, and ambulation training. 4) The need for the recreation category was 2.62. 2. Among the need for the effect related to the utilization of day care program, the need for survivors' physical and psychological well-being was highest and was followed by the need for caregiver's physical and psychological wellbeing. Pearson's correlation analysis revealed following results ; 1. The need for rehabilitation day care program service displayed a correlation with the level of education, ADL, and the level of depression, and a reverse correlation with age. 2. The need for the effect related to the utilization of rehabilitation day program displayed a correlation with the level of education, ADL, and the level of depression. The stepwise multiple linear regression analysis revealed following results : 1. For the need for rehabilitation day care program service, 28.4% of the variance was initially explained by one variable, level of depression. The level of depression plus two variables, survivors' age and ADL, explained 34.2% of the variance in the need for rehabilitation day care program service. 2. For the need for the effect related to the utilization of rehabilitation day care program, 12.4% of the variance was initially explained by one variable, level of depression. The level of depression plus one variable, level of education, explained 20.4% of the variance in the need for the effect related to the utilization of rehabilitation day care program. In conclusion, above characteristics should be considered when we are planning to develop stroke survivors' rehabilitation day care program.

The purpose of this study was to identify current housing status and housing awareness such as housing values, satisfaction, and preferences among households with one child. Data were obtained from a questionnaire completed by both husbands and wives living in metropolitan area and aged between 25 and 45. Selected variables were the age, education level, and employment status of housewives, ideal number of children, monthly income, plan to give birth, and so on. Using purposive sampling method, five hundred questionnaires were administered and 360 questionnaires were analyzed. In accordance with the questions related to housing values, housing satisfaction of respondents was examined. In order to compare the housing values, preferences, and satisfaction among diverse variables of respondents, mean, t-test, F test, Duncan's multiple range test, $x^2$ test, and factor analysis were used. The major findings of this study are as follows: First, there were significant differences in current housing type, tenure type, and floor area according to housewives' age, education level, monthly income, and plan to give birth. Interestingly, households not having a plan to give birth in the future were living in larger house than the households having a plan to give birth. Second, housing values of households with one child were divided into 4 factors-environmental comfort, economy and convenience, social status symbolism, and adequacy of space planning. Items related to privacy showed the biggest difference between housing values and housing satisfaction. Third, most of the respondents wanted larger house than current housing. However, the need for quality of housing including floor area and amenities was significantly higher among households not having a plan to give another birth than households having a plan to give birth in the future.

This study was conducted to comprehend the spatial distribution characteristics, habitats and appearances of Hydropotes inermis by using the biotope mapping in Daebudo Island, Ansan-si. The result is base data to understand status and manage potential inhabitation of Hydropotes inermis in Daebudo Island through the Maximum Entropy model. The study used 105 traces from the primary investigation and 452 traces in the secondary investigation. The biotope types were distinquished Hydropotes inermis habitats largest from the order of natural forest (15.1%), natural coast (13.7%), marshy cultivated land (12.6%), and dry cultivated land (11.7%), and from the inhabitation trace results. Hydropotes inermis appearanced biotope types were the greatest in the order of cultivated land (49.73%) > forest (18.85%) > coast (7.00%) > grassland (6.28%). Since forests in Daebudo Island have low slope and altitude, it was concluded that Hydropotes inermis would live in most of the forests. A high number of Hydropotes inermis was found to appear in areas where the grassland is formed including cultivated lands (include unused paddies and fields) and marshy grasslands, which would result in direct damage of crops. According to the Maxent modeling analysis that used location information of Hydropotes inermis, the AUC value was 0.635 based on the ROC curve. In Daebudo Island, areas with over 0.635 potential inhabitation value are distributed all over the place, and it was concluded that each population would have a different scope of influence and home range. Hydropotes inermis living in Daebudo Island have high habitat suitability mainly around the cultivated lands near the roads, but due to the bare lands and roads, it is expected that their habitats would be fragmented and damaged, which would have a direct and indirect effect in maintaining the Hydropotes inermis population. Also, considering habitat disturbance, diverse methods for reducing damage including capturing some individuals within the limit that does not disperse Hydropotes inermis population in Daebudo Island must be carried out.

This study examined Korean employees' meal structure characterized by mealtime, meal places, and companions. The data from 19,692 time diaries, recorded by 9,846 employees aged 19-64 years for two days in the 2014 Korean Time Use Survey, were analyzed for working days and non-working days. Approximately two-thirds of Korean employees ate meals three times a day on both working and non-working days. The breakfast and lunch-times on working days were distributed within two hours, but the dinner time on working days and all three meals on non-working days were dispersed across a three-hour range. Male employees spent three minutes on meal preparation on working days, whereas females spent 30 minutes. On working days, 88% of breakfasts and 67% of dinners were eaten at home. For lunches, 46% were eaten at restaurants, and 42% were at workplaces. The breakfast on working days showed the highest percentage of eating alone (40%) and the dinner on non-working days appeared highest in the percentage of eating with families (69%). The characteristics of Korean employees' meal structure appeared different on working days and non-working days. Such characteristics should be considered in the process of planning nutrition policies and programs for employees.
