The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social, economical influence of the elderly population has been increasing, too. Research regarding elderly people is important because many elderly people take care of their appearance and clothing, and clothing plays an important role in the elderly women's everyday life. This study investigated the life satisfaction, appearance satisfaction, and clothing behavior of women aged 55 years and older who were residents of Seoul. The results of this study are as followings: 1. The importance of various factors on clothing behavior is different. They are management, clothing importance, fashion indifference, information search and purchase planning, clothing dependence, status symbol, and conformity in order of the importance. 2. Age has a positive relationship with each of fashion indifference and clothing dependence, but a negative relationship with information search and purchase planning. 3. Age has a positive relationship with each of life satisfaction and allowance. 4. Appearance satisfaction is positively related with age, but is significantly related with neither allowance nor education. 5. There are positive relationships between life satisfaction and all clothing behavior factors except status symbol. 6. Appearance satisfaction are siginicantly correlated with management, conformity, clothing dependence, and clothing importance. And life satisfaction has more significant relationship with clothing behavior than appearance satisfaction does.

Switch rail is a very important part on the railway track, which not only accounts for the safety of the passing trains but also greatly influences the speed of the train. The higher the speed and the loads of the train the more it demands on the properties of the switch rail. Research shows that the higher mechanical properties of switch rail the longer the service life. Induction heat treatment is a good way of improving the mechanical properties of metallic materials. But the switch rail's section area changes gradually across the lengthways, which is difficult for induction heating especially for the small section. And the mechanical property of small section of the switch rail is the most important for its service life. The induction heat treatment used past always brings the low hardness on small section which can cause low service life of switch for wearing, or too high hardness because of martensite microstructure which can cause the shelling or even breaking of the switch rail. To prolong the service life of switch rail by higher mechanical properties, we researched the improved induction heat treatment for switch rail by adjusting speed of heating, and adopting compressed air cooling. The results showed that switch rail obtain almost the same high hardness across the length way after the improved induction heat treatment, which is very helpful to extend the service life of switch rail.

This research was conducted to provide basic document on efficient health promotion behavior program that elementary school students can use from elementary school course to enhance health promotion behavior for healthy life by checking out the degree of the most influential factor for health promotion behavior about elementary school students who establish lifelong health habit, and by checking out the relation between the degree of self-efficacy and health promotion behavior. The number of subjects of this research was 598. They were all elementary school students from the sixth grade students of the 5 cities of the Kyeong Nam province. We conducted questionnaires and did statistical analyses by using 592 papers which were suitable for date analyses with SPSS. The conclusions were as follows; A. The degree of self-efficacy The degree of self-efficacy of elementary school students was more than average. The degree of self-efficacy on physical activity was the highest and the degree of self-efficacy on self-fulfillment was the lowest. The degree of self-efficacy of girl students was comparatively higher than that of boy students. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest in health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. B. The degree of health promotion behavior Although the degree of health promotion behavior of elementary school students was a bit lower than the degree of self-efficacy, it was higher than average. The degree of health promotion behavior on physical activity was the highest. But the degree of health promotion behavior on health of their own was the lowest. The degree of health promotion behavior between girl students and boy students was the same. When their parents got higher education, made a lot of money and kept harmony with their children, the degree of self-efficacy became high. Furthermore, when their parents or themselves have a lot of interest In health, they feel that they are healthy, and they feel that they are satisfied with their bodies, the degree of self-efficacy was high too. C. The relation between self-efficacy and health promotion behavior When the degree of self-efficacy was high, the degree of health promotion behavior was high too. So there was high positive relationship between self-efficacy and health promotion behavior. Physical activity showed the highest relationship. The order of strong relationship run as follows. Relationship with others, self-fulfillment, management of stress. The higher self-efficacy which was a recognizable factor on health behavior, the higher the degree of health promotion behavior. It is being revealed that many modem chronic diseases are cause by accumulated careless attitude on harmful health habit and lack of self-control. The behavior of keeping healthy and enhancing health is more firm when they have high self-efficacy which is believing their own conviction. So, When we teach elementary school students health promotion education at school, we should try to enhance their own self-efficacy rather than just instill simple information about health. By doing so, we can help them change their attitude on health. Then, they could enjoy life-long healthy life.

This study intends to : 1) confirm the possibility to transform the enumerated scheme into the faceted scheme, 2) review general theories on facet structure employed in DDC of the enumerated scheme, 3) analyze the facet structure of life science and literature in DDC, and 4) comparison of the facet structure of life science and literature in DDC and CC. This study suggests following conclusions. 1) CC follows throughly the classification principles by Ranganathan, but all classification theories are not property applied to DDC yet. 2) Because DDC does not have any formula to classify the compound subject, but has to follow the compounding methods presented in each subject, its facet structure is too complicated. 3) DDC has transformed the entire system into the facet structure through its revision. Expecially the life science transformed into the facet structure employed the facet indicators and applies them to all the systems in life science. But the notations have sometimes twofold meanings, and no ability to differentiate the meanings in the same notation,. When DDC follows the classification method by facet, the number of items for classification so limited that it is difficult to array the subdivision and that length of notation becomes longer and longer.

Receptor for advanced glycation end products (RAGE) is one of the single transmembrane domain containing receptors and causes various inflammatory diseases including diabetes and atherosclerosis. RAGE extracellular domain has three consecutive IgG-like domains (V-C₁-C₂ domain) which interact with various soluble ligands including heparan sulfate or HMGB1. Studies have shown that each ligand induces different oligomeric forms of RAGE which results in a ligand-specific signal transduction. The structure of mouse RAGE bound to heparan sulfate has been previously determined but the electron density map of heparan sulfate was too ambiguous that the exact position of heparin sulfate could not be defined. Furthermore, the complex structure of human RAGE and heparin sulfate still remains elusive. Therefore, to determine the structure, human RAGE was overexpressed using bacterial expression system and crystallized using the sitting drop method in the condition of 0.1 M sodium acetate trihydrate pH 4.6, 8 % (w/v) polyethylene glycol 4,000 at 290 K. The crystal diffracted to 3.6 Å resolution and the space group is C121 with unit cell parameters a= 206.04 Å, b= 68.64 Å, c= 98.73 Å, α= 90.00°, β= 90.62°, γ= 90.00°.

Death has been one of the basic objects in philosophy and religion. Why do people feel afraid about death? Maybe it is because they don't know the situation after death or because they have a wrong idea about it. Someone may think that he/she doesn't care the situation. But this attitude is wrong. We must understand that our attitude about life is shaped by our knowledge of the situation after death. A recurrent theme about death in popular thought is the idea that death is mysterious. As we have seen, it is difficult to formulate a satisfactory philosophical analysis of the concept of death. If it is impossible to analyse the concept of death, then it is impossible to explain precisely what we mean when we say that something dies. It might be said therefore that, in virtue of this fact, death is mysterious. Of course, death is not distinctively mysterious - all other unanalysable concepts are equally mysterious in this way. Reflection on death gives rise to a variety of philosophical questions. One of the deepest of these is a question about the nature of death. Typically, philosophers interpret this question as a call for an analysis or definition of the concept of death. Plato, for example, proposed to define death as the separation of soul from body. However, this definition is not acceptable to those who think that there are no souls. It is also unacceptable to anyone who thinks that plants and lower animals have no souls, but can nonetheless die. Others have defined death simply as the cessation of life. This too is problematic, since an organism that goes into suspended animation ceases to live, but may not actually die. The eastern philosophers proposed to define death as the nonduality of life and death. Taoists, for example, do not believe in the Wheel of Life of the Buddhists nor in the Heaven or Hell of Christianity. Taoists view existence as glorious. The whole Universe, they teach, is a marvelous, vibrant Unity wherein everything, visible and invisible, pulses with energy and changes. As being develops through the experience of existence, its vessels are swept onwards by the mighty stream of the eternal TAO to other forms of expression and activity. Man does not die; he merely extends into new fields. Taoists teach that the end of a person is the return to the Ultimate Reality. "Life is uncertain - Death is certain": This is a well known saying in Buddhism. Knowing very well that death is certain and it is a natural phenomenon that everyone has to face, we should not be afraid of death. Yet, instinctively, all of us fear death because we do not know how to think of its inevitability. We like to cling to our life and body and so develop too much craving and attachment.

In this paper, we discuss about the implementation of CITIS(Contractor Integrated Technical Information Service) which is information infrastructure for CALS. CALS concept is introduced by DoD(Department of Defense, US) to exchange technical data of product's life cycle electronically. This CALS concept is accepted by commercial industrial area and considered as a part of global concept of Electronic Commerce. CITIS- a service defined by MIL-STD-974- is about to be implemented by commercial industrial society, too. But, until now there is a few sites implementing CITIS and especially in Korea. In this paper, we discuss characteristics of some CALS/CITIS implementation and solutions, and introduce ETRI-CITIS.

This paper presents a method to estimate a storage life for loss of stabilizer content as storage periods using accelerated life test data. The estimate of storage life based on deterministic accelerated life test and degradation data cannot describe a condition distribution and storage life distribution. Previously, the method to show the condition distribution and storage life distribution by using gamma process has been studied. But it has limitation because it is impossible to collect the deterioration data at initial production phase. The estimated storage life presented by this study shows the similar value to previous studies and the method can describe the condition distribution and storage life distribution. So, the estimation method studied in this paper can be used for a life cycle management about deterioration of propellant for propulsion unit or components of missile, too.

The purpose of this study is to investigate the moderating effect of interpersonal relationship skills in adapting military life and stress in the army. For this purpose, 453 soldiers in Chungnam and Daejeon were surveyed. First, the main result of this study is the difference in interpersonal skills and group life adjustment in accordance with the rank and class of the soldiers. Second, too much stress can cause difficulty to adapt military life and interpersonal skills. Also high interpersonal skills can help to adjust well to military life. Third, according to the survey, it was confirmed that the openness in the sub-factors of military life and military life stress was effective. This study suggests that it is important to help control the stress of military life to improve the ability of the openness of interpersonal skills in order to increase the adaptability military life.
