도시에 불투수면적이 증가하고, 기후변화가 극심해져감에 따라 홍수 및 열섬현상과 같은 도시의 물 문제가 발생하고 있다. 이를 해결하기 위한 정책의 일환으로 우리나라의 녹색건축인증제도(Green Standard for Energy and Environmental Design, G-SEED)에서는 물순환 관리를 평가하고 있다. 하지만, 현재 G-SEED의 평가방법을 살펴보면 빗물관리시설의 설치 정도로 평가하고 있고, 강우 특성 또한 고려되고 있지 않다. 그러므로 본 연구에서는 G-SEED의 빗물관리 및 이용 항목에 대해 수문 모델을 통해 효과를 정량화함으로써 성능에 따라 평가할 수 있는 방법을 제안하였다. 빗물관리 항목에서는 유출저감률을, 빗물이용 항목에서는 빗물이용률을 평가지표로 선정하였고, 각 평가인자를 산출하기 위하여 개념모델을 적용하였다. 빗물이용시설의 경우 초기우수배제장치 용량과 필터 효율에 따른 빗물유입량의 변화와 급수인원에 따른 수요량 변화를 고려한 수문모델을 개발하였고, 수요량과 빗물저장조 용량에 따른 유출저감률과 빗물이용률을 알아보기 위해 MATLAB을 이용하여 모의해보았다. 또한, 옥상녹화의 경우에는 강우, 저류, 증발산, 유출을 고려한 수문흐름모델을 적용하였고, 토층의 두께와 배수(저장) 층의 용량에 따라 모의하여 평가기준을 선정하였다. 제안된 수문모델의 검증을 위하여 서울대학교 기숙사와 35동 옥상녹화의 실측데이터를 비교하였고, 적용성 평가를 위해 RMSE(Root Mean Square Error)와 NSE(Nash-Sutcliffe Efficiency)를 이용하였다. 본 연구에서 제안된 방법을 통해 빗물관리시설의 수문학적 성능에 따른 평가가 가능해질 것이며 설계자와 건축가들로 하여금 실질적인 효과를 내는 시설을 설치하게끔 유도할 수 있을 것이다.

The purpose of this study was to analyze the effects for lifestyle, stress and life satisfaction on sleep quality in university students. The participants were 46 university students attending the department of occupational therapy. Participants responded to responses to the lifestyle questionnaire and Morning and Evening Questionnaire-Korean version(MEQ-K). The levels of stress and life satisfaction reported by participants were obtained using the Korean version of Perceive Stress Test-4(K-PSS-4) and Korean version of Satisfaction With Life Scale(K-SWLS). The quality of sleep was assessed using Korean Modified Leeds Evaluation Questionnaire(KMLSEQ). An independent t-test, Pearson correlation analysis, and multiple regression analysis were performed to investigate factors related to quality of sleep. The analysis of correlations between health status, morning type of chronotype, and life satisfaction showed a significant positive correlation between quality of sleep. As a result of analyzing the quality of sleep according to the chronotype, the main family house and dormitory group showed higher sleep quality than the boarding group. As a result of the multiple regression analysis, the chronotype predicts quality of sleep. This study could provide information to improve the quality of sleep for university students by identify factors affecting sleep for university students in occupational therapy.

The number of antibiotic-resistant bacteria is increasing rapidly while the discovery rate of new antibiotics is in decline. A systematic study is therefore necessary to investigate which bacteria are resistant to medically important antibiotics and how high that resistance is. To that end, this study aimed to analyze which bacteria demonstrated resistance to ampicillin, one of the currently most-widely used medical antibiotics. Water samples were collected from the Changwon-Cheon that runs through Changwon City and from the pond in front of the dormitory building at Changwon University. Hundreds of ampicillin-resistant colonies were obtained and 22 morphologically distinct examples were chosen for further study. These bacteria were identified by amplifying their 16S rRNA genes and comparing those sequences with data in GenBank. The bacteria was identified as belonging to 10 families, 12 genera, and 17 species, and all were able to grow in the presence of $50{\mu}g/ml$ ampicillin while seven showed growth at ampicillin concentrations as high as 1.5 mg/ml.

By developing rider robot using omni wheel drive, a usability test for 6 people was conducted after finding out inconvenient factors and ways of improvement. The results of this research are as follows. First, we researched inconvenient factors captured by object of experiment using a rider robot who is living in the dormitory. It showed that the disabled showing 1.6 of satisfaction degree felt more inconvenient for normal people showing 4 of satisfaction degree. It was found that the height of seats is 10 centimeters higher, which caused inconvenience for moving. Second, each of the disabled and normal people showed 2.33 and 2.62 of satisfaction degree below the average for seats, back of a seat, armrest, footrest, security belts. However, for the revised design both of them showed 3.5 of satisfaction degree over the average. Third, most people felt this robot is quite expensive and said they would purchase it if subsidized by the government. Therefore, based on inconvenient factors and ways of improvement found in this research, further study needs to be conducted so as to improve the quality of life of the disabled.

The authors studied anxiety, using Zung's Self-Rating Anxiety Scale (SAS), in the subjects of 3,893 male and 1,976 female college students of Yeungnam University. The authors collected the reports of SAS during the periods from October to November, 1984, and applied ANOVA and t-test on the anxiety scores in order to compare them between various psychosocial factors, and sexes. The results could be summarized as follows: There was significant difference in the mean averages of total anxiety score's between male and female students ; male students scored $36.92{\pm}7.07$, female students scored $39.63{\pm}7.51$, p<0.001. The anxiety scores relating to the items of sweating, apprehension, restlessness, insommia, dyspnea were relatively higher in both groups. The anxiety scores in the items of paresthesias, mental disintegration, tremors, faintness, dizziness were lower in both groups. Two hundred and one male students (5.2%) showed seriously high anxiety scores of 50 or higher, while 201 female students (10.2%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but females showed more various symptoms and higher level of anxiety than males. In a comparison between male students in different school grades, freshmen showed the highest level of anxiety scores and as the grades of the students became higher, the levels of anxiety scores were lower. The female students who resided in dormitory or other residences, and whose educational fees were paid by brothers or sisters, showed higher level of anxiety scores. There was a strong tendency toward higher anxiety scores in the students who were dissatisfied with their colleges or departments, and who had pessimistic views of self image in the past, present, or future, in both groups.

The purposes of this study were to : (a) analyze university students' perception and patronage behaviors to the service quality dimensions, and (b) assist university residence hall foodservices in formulating improved managerial strategies. Questionnaires were hand delivered and mailed to 1,210 university students residing in the residence hall and 13 foodservice managers. A total of 1,011 was usable; resulting in 83.6% response rate. The survey was conducted between October, 1998 and May, 1999. Statistical data analysis was completed using the SAS/Win 6.12 for Descriptive Analysis, $x^2-test$, T-test, ANOVA, and Stepwise Multiple Regression. Forty-seven percent of the respondents indicated that 'taste' was their first priority when choosing a menu. The reasons behind choosing residence hall foodservice were 'location', 'board plan', 'price', 'taste', 'opening hours', and 'menu variety'. The main reasons of dissatisfaction with the residence hall foodservice were 'board plan', 'taste', 'menu variety'. The overall satisfaction score was 2.99 out of 5. The satisfaction score of ${\ulcorner}convenience{\lrcorner}$, ${\ulcorner}food\;quality{\lrcorner}$ and ${\ulcorner}menu\;variety{\lrcorner}$were 3.25, 2.94 and 2.76, respectively. Generally, male students were more satisfied than females. Graduate students and students living in residence halls over six semesters were the most dissatisfied with the residence hall foodservice. Residence hall students were dissatisfied with the variables ${\ulcorner}menu\;variety{\lrcorner}$ and ${\ulcorner}facilities{\lrcorner}$in 'self-operated' operations, whereas ${\ulcorner}food\;quality{\lrcorner}$, ${\ulcorner}menu\;variety{\lrcorner}$ and ${\ulcorner}price{\lrcorner}$ in 'contracted' operations. Foodservice operations with 'less than 1,000 meals serving per day' was the highest satisfaction score(3.36) among other serving sizes. Meal price with 'less than 1,300 won' was most satisfied with students. When overall customer satisfaction and service quality dimensions were analyzed by Stepwise Multiple Regression ${\ulcorner}food\;quality{\lrcorner}$(p<.001), ${\ulcorner}price{\lrcorner}$(p<.001), ${\ulcorner}facilities{\lrcorner}$(p<.001), ${\ulcorner}convenience{\lrcorner}$(p<.001), ${\ulcorner}menu\;variety{\lrcorner}$(p<.001), ${\ulcorner}manager's\;attitude{\lrcorner}$(p<.0l), and ${\ulcorner}atmosphere{\lrcorner}$(p<.01), in decreasing order, significantly impacted on ${\ulcorner}overall\;customer\;satisfaction{\lrcorner}$.

Recently, the proportion of single-person households is on the increase in Korea, expected to reach 34.6% in 2035. Among the single-person households, Young single family households are facing greater difficulties due to high house prices in Korea. The government is expanding its support to Young single family, executing various policies such as public lease housings, private lease housings for youth, youth dormitory, etc. The purpose of this study is to understand the exact housing requirement of Young single family households who have different lifestyles with other age groups and provide base line data for youth house planning which will be in use later on. Study methods are shown below. First, this research studied the status and characteristics of Young single family households by looking into literature. Second, by studying previous studies concerned with life style and housing preferences of youth, the tool for investigating preferences and needs of housing environment by Young single family households was composed. Third, survey on characterstics of space usage, preferences and needs on flat composition, and preferences of interior design were conducted based on lifestyle of Young single family-households. The survey was conducted as an online survey using SNS for 150 Young single family holds from the age of 20 and 39, including students and office workers from December 2018 to January 2019. The results are as following. (1) Looking into the space usage characteristics, considering that various activities other than basic functions take place in bedroom and living room of small-sized Young single family households, we need to consider this additionally when planning the housing. (2) Looking into the preferences and composite needs of flat composition, the subjects demand separate bed room and more living room space, and also demand expansion of living room space where various activities take place and additional storage such as dress room in bed room (3) The preferences toward interior design show preferences toward modern style and achromatic color, a representative color. The subjects also prefer floor finishing materials normally used for living spaces, and indirect, soft lighting that uses wall. Also, there are differences between interior design preferences between students (20's) and office workers(30's) due to their different lifestyles. Research is needed to propose practical residential environment requirements and plans through a case study of actual public rental housing and a wider range of users.
