To study fauna of Silla University located in Mt. Baek-yang, we conducted six surveys from 29 May 2011 to 28 April 2012. We found five phyla 41 orders 197 species of animals inhabiting in this area: four phyla 27 orders 163 species of invertebrates and in vertebrates one order six species of fishes, three orders nine species of amphibians and reptiles, six orders 14 species of aves, and four orders five species of mammals. Of these species, some Korean endemic species were included: a fish of Rhodeus uyekii in a pond near main gate of this university, a frog of Rana coreana in a creek near a dormitory, and a rabbit of Lepus coreanus and a water deer of Hydropotes inermis in a grass region near a main stadium. A kind of hawk, Falco tinnunculus as a natural monument (animal) of no. 323-8, was observed on a building of medical and life science. A blue frog of Hyla japonica as a variation was found near a spring resort. Therefore, this area is considered an ecologically important area having a high animal diversity.

The purpose of this study is to investigate effects of day care environmental variables on young child psychological well-being. The subjects of this study were 63 teachers and 949 young children in 26 day care center, Cronbach's α, Frequency, Correlation, Multiple Regression for statistical analysis were conducted for data analysis. The major findings of this study were as follows: (1) The significant variables which had positive correlation of young child psychological well-being were air conditioning, frequency of safety accident, institution safety, education schedule, satisfaction of program, preparation of playing, health, nutrition and teacher experience. The significant variables which had negative correlation of young child psychological well-being were dare care time per one day of young child, young child's experience of day care center moving, young child's frequency of dare care center moving, the ratio of a teacher : young child and teacher's duty time. (2) The significant variables which had effects of young child psychological well-being were frequency of safety accident, education schedule, preparation of playing, nutrition, young child's frequency of day care center moving, teacher experience and teacher's duty time.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

The dried stem bark of Albizia julibrissin was extracted in 70% aqueous EtOH, and concentrated extracts were partitioned with EtOAc, n-BuOH, and H2O, successively. From the EtOAc fraction, three triterpenoids were isolated through repeated silica gel and octadecyl silica gel column chromatography. Based on nuclear magnetic resonance spectrometry (NMR), mass spectrometry, and infrared spectroscopy spectroscopic data, the chemical structures of the compounds were determined to be lupeol (1), betulinic acid (2), and oleanolic acid (3). This was the first report in which compounds 1, 2, and 3 were isolated from the stem bark of A. julibrissin. Since the NMR data for some compounds have been incorrectly or incompletely identified in previous literature, the NMR were revised on the basis of 2-D NMR experiments. Compounds 1, 2, and 3 showed inhibition activity on ACAT-1 with values of 89.3±3.7%, 61.2±3.4%, and 52.5±0.7%, respectively, at a concentration of 50 μg/mL and on ACAT-2 with values of 44.3±2.1%, 55.5±0.3%, and 22.0±2.6%, respectively, at a concentration 50 μg/mL.
