Sarcopenia is a condition in which muscle mass, strength, and performance decrease with age. It is associated with chronic diseases such as diabetes, cardiovascular disease, and hypertension, and contributes to an increase in mortality. Because managing sarcopenia is critical for maintaining good health and quality of life for the elderly, the condition has sparked concern among many researchers. To counteract sarcopenia, intake of protein is an important factor, while a lack of either protein or vitamin D is a major cause of sarcopenia. In addition, essential amino acids, leucine, β-hydroxy β-methylbutyrate (HMB), creatine, and citrulline are used as supplements for muscle health and are suggested as alternatives for controlling sarcopenia. There are many studies on such proteins and supplements, but it is necessary to actually organize the types, amounts, and methods by which proteins and supplements should be consumed to inhibit sarcopenia. In this study, the efficacy of proteins and supplements for controlling sarcopenia according to human clinical studies is summarized to provide suggestions about how the elderly may consume proteins, amino acids, and other supplements.

Proteomics is a leading technology for the high-throughput analysis of proteins on a genome-wide scale. With the completion of genome sequencing projects and the development of analytical methods for protein characterization, proteomics has become a major field of functional genomics. The initial objective of proteomics was the large-scale identification of all protein species in a cell or tissue. The applications are currently being extended to analyze various functional aspects of proteins such as post-translational modifications, protein-protein interactions, activities and structures. Whereas the proteomics research is quite advanced in animals and yeast as well as Escherichia coli, plant proteomics is only at the initial phase. Major studies of plant proteomics have been reported on subcellular proteomes and protein complexes (e.g. proteins in the plasma membranes, chloroplasts, mitochondria and nuclei). Here several plant proteomics studies will be presented, followed by a recent work using multidimensional protein identification technology (MudPIT).

My paper aims to discuss the possibility of training Korean Studies professionals in Eastern Europe. This paper has two aspects. One was discussed in three aspects about the role of Korean Studies experts in the local area. In addition, discussions were held in various aspects, focusing on the possibility of fostering Korean Studies scholars in Eastern Europe, with a focus on the Babes-Bolyai University in Romania, Eőtvős Lorand University in Romania, and Sofia St. Kliment Ohridski University in Bulgaria. For this study, concretely compared situation of lectures, students, professors in Korean Studies managed by these Universities. After addressing them in depth, suggested realistic improvements of problems which these Universities have in common. Especially in order to complement insufficient lectures of Korean Studies in these Universities, using the CEEPUS(Central European Exchange Programme for University Studies) actively which is operated by some of Universities in Eastern Europe is one of good methods and more need to expand the CEEPUS for developing Korean Studies in this area. And for developing teaching materials of Korean Studies suitable for local situation, local experts in Korean Studies and experts related fields in Korea need to highly cooperate with each other. As a final suggestion, for maintaining and developing the major of Korean Studies in Universities of Eastern Europe is very important in order to cultivate Korean Studies professionals in Eastern Europe.

The purpose of this research is to bring out some practical issues of housing studies prblished by Home Economics researchers since 1980. There were 299 articles related to housing in three major journals such as Journal of the Korean one Economics Association Journal of Korean Home Management Association and Housing Research Journal. It has been remarkable progress in terms of the quality as well as the number of articles during 20 years. However this study could be brought out some research issues in the methodological and theoretical aspects to improve the applicability of housing studies to dedicate family life and housing policies.

The purpose of this study was to explore the effects of parental differential treatment and social support perceived by adolescents with siblings with special needs on their self-esteem and internalized problems. The subjects comprised one hundred 12- to 18-year-old adolescents with siblings with special needs. The major results of this study were as follows. First, there were significant differences in adolescents' self-esteem by participation in support programs for siblings of children with special needs. Second, there was no significant effect of parental differential treatment on adolescents' self-esteem. Third, there was a significant effect of social support (family, friends, and teachers) on adolescents' self-esteem. Fourth, there was no effects of paternal differential parenting on adolescents' internalized problems. However, there was a significant effect of differential maternal affection on adolescents' internalized problems. Fifth, there was a significant effect of social support, especially in terms of support provided by friends, on adolescents' internalized problems. In conclusion, social support and differential maternal affection both have an important role in adolescents' self-esteem and internalized problems.

The purpose of this study was to explore the perception toward qualification of early childhood English teachers and their teachers' sense of efficacy. The samples consisted of 201 early childhood English teachers in Seoul, Daejeon, Daegu, Gyeonggi area. A sample of early childhood English teachers completed a series of questionnaires. The collected data were analyzed with t-test, F-test, correlation. The results showed that most teachers were women between 30 to 40 years old, university graduate with job experience less than 3 years. In addition, half of teachers in this study majored on English studies or early childhood education and child studies. This study found that early childhood English teachers thought themselves to be qualified as a English teacher and early childhood teacher. And they rated teachers' sense of efficacy to relatively high. There were differences on the scores of qualification of early childhood English teacher and teachers' sense of efficacy according to education level and major. And years of job experience were positively related with the perception of qualification of early childhood teacher and teachers' sense of efficacy.

Bacteriophage E3 grows very rapidly and forms a large size plaque with a diameter of 1 cm. The promoter controlling the expression of the gene encoding the major capsid protein is thought to be most efficient. To find out this promoter, this gene was mapped in the genome according to the following procedure. The major capsid protein was purified from phage particle and the N-terminal amino acid sequence was revealed. Based on this sequence,a degernerate oligonucleotide probe was designed and used for screening of the genomic DNA fragments. From the DNA sequence of the selected clone, the gene encoding the major capsid protein was mapped at 70% of E3 genome. The expression of this gene was not sensitive to rifampicin which indicated the presence of E3's own RNA polymerase.

Purpose. The purpose of this review is to explore cultural influences on the experiences of Korean, Korean American, and Caucasian American family caregivers caring for frail older adults in terms of the selection of a primary caregiver, caregiving motivation, support/help-seeking, and negative emotional responses (depression and burden). Methods. Seven electronic databases were searched to retrieve studies from 1966 to 2005. Thirty-two studies were identified. Results. This review supported cultural influences on the selection of primary caregiver, caregiving motivation, and support/help-seeking among the three caregiver groups. In Korean caregivers, the major primary caregivers were daughters-in-law while among Korean American and Caucasian American caregivers, the major primary caregivers were daughters or spouses. As a major caregiving motivation, Caucasian American care￢givers reported filial affection while Korean caregivers and Korean American caregivers reported filial obligation. Korean caregivers reported higher extended family support, while Caucasian American caregivers reported higher utilization of formal support. Korean caregivers showed the highest levels of depression followed by Korean American caregivers and Caucasian American caregivers. Conclusion. In order to develop culturally appropriate interventions and policies, more research is needed to further explain these differences among the three groups, especially regarding support/help-seeking and negative emotional responses.

Objective : Several studies hove suggested that reduction of cholesterol concentration and low cholesterol level increases suicide, homicide, and depression. The authors sought to determine whether low cholesterol is associated with a history of suicidal attempts among major depression patients. Method : The subjects were 105 patients with major depression, diagnosed according to the DSM-III-R criteria, and 105 age, sex matched healthy controls. Blood was token following overnight fast and serum cholesterol concentration were measured by a enzymatic method Results : The serum cholesterol level was significantly lower in the patients with major depression than in healthy controls($180.4{\pm}43.4mg/dl$ vs $199.7{\pm}35.8mg/dl$). And the serum cholesterol level was significantly lower in major depression patients with suicidal attempt than in major depression patients without suicidal attempt($156.7{\pm}38.2mg/dl$ vs $ 187.8{\pm}42.5mg/dl$) Conclusion : It is hypothesized that low cholesterol level is associated with depression by modifying the serotonin metabolism and the production of interleukin-2, low cholesterol concentration should be further investigated as a potential biological marker of suicidal risk in major depression. Prospective study with serial cholesterol determinations should be done.
