Space is full of energetic events emitting high-energy radiations which may be fatal to all living things unless protected. The present paper briefly describes high-energy photons and particles incident on Earth surface and their common properties toward living things. Role of radiation played in evolution of life and earth environment will be presented.

The peels of Carya cathayensis Sarg. (PCCS) were treated under subcritical water conditions ($130^{\circ}C$ to $280^{\circ}C$ for 0 to 120 min). The extract from PCCS included reducing sugar, proteins, and compounds with radical scavenging activity. Addressing the reducing sugar that is a resource of bioethanol, we could maximize the reducing sugar under the subcritical water ($190^{\circ}C$ for 60 min) and obtain 0.24 g/g-sample together with 9.7 units/mg-sample of radical scavenging activity. The obtained extract was estimated to correspond to 1 L of bioethanol/100 g-sample. It was therefore considered that the treatment by subcritical water could yield reducing sugar and natural compounds with radical scavenging activity.

The objective of our study was the formulation of a local strain of Mamestra brassicae nucleopolyhedrovirus-K1 (MabrNPV-K1) for the development of viral insecticide to control M. brassicae. To formulate MabrNPV-K1, feeding toxicities of various supplements and ultraviolet (UV)-protection were investigated. Optical brightener Tinopal UNPA-GX (Tinopal) as UV protectant and Bentonite had some toxicity themselves to increase the mortality. The protection of polyhedra from UV light radiation was observed only by Tinopal. The MabrNPV-K1 was formulated as a wettable powder form. The mortality of the formulation was higher and rapid than that of the un-formulated. This suggested the possibility of MabrNPV-K1 formulation as an effective biological control agent for M. brassicae.

The purpose of this study is to investigate the influence the need for improvements to dormitory environments and to study the stress from school-life according to residential satisfaction in dormitories and housing. For the purpose of this study, a survey was conducted including a questionnaire consisting of a residential satisfaction scale, a need of dormitory environment improvement scale, and a school-life stress scale. The subjects were 453 special purpose students in Daegu and Gyeongsangbuk-do who all live in a dormitory. Factor analysis, Cronbach' $\alpha$ and MANOVA were employed for data analysis, and Scheffe test was used for post-hoc analysis. First, the lower group the satisfaction of a physical residential environment in a dormitory, the more likely it is that the dormitory environment need improvement. The result of this study suggests that dormitory students are much more sensitive to conditions relating to physical residential satisfaction than to sociopsychological residential satisfaction. Also, the residents believe that change to these physical residential conditions facilitate an improvement to sociopsychological residential satisfaction. Moreover, when the satisfaction of a physical residential environment is lower group, more perceptive stress occurs from academic, health and personal factors while a lower satisfaction for the sociopsychological residential environment results in a more perceptive stress from the environment. The result of this study suggests that dormitory conditions indicate the necessity of improving the environment to adapt well to school-life, thus reducing stress. Also when simply providing a supplementary physical residential environment the sociopsychological residential environment should be considered, as this can cause conflicts between roommates. Second, the lower group the satisfaction for a physical residential environment in housing, the more likely it is that the dormitory environment need improvement. The result of this study suggests that for environments of inadequate housing there is a strong urge towards needing more independence and a better living environment. Third, when group feel there is a more substantial difference in the physical residential environment between dormitories and housing, it is more likely it is that the dormitory environment need to be improved. Also, when they feel there is more substantial difference in the sociopsychological residential environment between dormitories and housing, a more perceptive stress is detected from the environment. The result of this study suggests that dormitory students want to have the same level of conditions as those provided in housing. Also, dormitory students want to need more physical environment improvement than sociopsychological environment improvement.

The purpose of this study was to investigate the influence of home environment school life adjustment and demographic variables on the adolescents' clothing attitudes The subjects were 682 middle and high school boys and girls(boys. 342, girls:340) in Seoul Korea. Modesty of boys was influenced by parent's education(-) academic record achievement tendency of home and allowance(-) $(R^2$=8.6%) and girls influenced by affection of home(-) allowance(-) age and academic record$(R^2$=11.2%). Clothing satisfaction of boys was influenced by parents' education self-control tendency of home and school life adjustment$(R^2$=19.4%). girls influenced by allowance affection of home parents' education school life adustment and self-control of home$(R^2$=20.3%) Age was most important in predicting the wearing of regulative clothes of boys. followed by allowance and academic record(-)$(R^2$=26.7%) allowance was most important in girls followed by academic record(-), and achievement tendency of home $(R^2$=19.0%). The present findings mean that the more allowance adolescents received and the lower the academic record the lower the modesty and the their the wearing of regrlative clothes. The school life adjustment and home environment such as achievement affection and self-control tendency were meaningful variables That affect clothing attitude of adolescent.
