The proportion of the elderly in rural area(21.7％) is four times more than that of the urban area (5.4％) in Korea. With this rapid aging of the population in rural Korea there has been growing concern about the quality of life of rural elderly. Compare to urban elderly, rural elderly experience many disadvantages, especially in terms of limited offering of social/educational programs. Their social/educational needs are rarely assessed and there are few programs geared to the needs of rural elderly. In this regard, this study aims (1) to identify education and activity program needs of the rural elderly related to three dimensions: Family life, Farming life, and Community activities and (2) to develop education and activity programs for the rural elderly based on the needs assessment. For this purpose, data are gathered from 413 rural elderly and 110 community welfare specialists, using a structured questionaire. The statistical methods used for data analysis are descriptive statistics, cross tables with SPSS wins 10.0 program. The major findings of this study are as follows: Majority(94.1％) of the rural elderly wants to participate in diverse social/educational programs. They want to have programs dealing with 'relationship enhancement with children', 'nutrition', 'health and care', 'farming skill', 'gardening', 'volunteering', etc. Based on these results, we develop eight types of education program and four types of activity program, according to the priority of their needs in each dimension. There are four sessions of Family life program, and four sessions of Community activities program. The effect of these programs will be evaluated by taking pretest and protest in local basis.

The gene encoding Pyrobaculum arsenaticum DNA polymerase (Par DNA polymerase) was cloned and sequenced. The gene consists of 2,361 bp coding for a protein with 786 amino acid residues. The deduced amino acid sequence of Par DNA polymerase showed a high similarity to archaeal family B-type DNA polymerases (Group I), and contained all of the motifs conserved in the family B-type DNA polymerases for $3'{\rightarrow}5'$ exonuclease and polymerase activities. The Par DNA polymerase gene was expressed under the control of the T7lac promoter on the expression vector pET-22b(+) in Escherichia coli BL21-CodonPlus(DE3)-RP. The expressed enzyme was purified by heat treatment, and Cibacron blue 3GA and $Hirap^{TM}$ Heparin HP column chromatographies. The optimum pH of the purified enzyme was 7.5. The enzyme activity was activated by divalent cations, and was inhibited by EDTA and monovalent cations. The half-life of the enzyme at $95^{\circ}C$ was 6 h. Par DNA polymerase possessed associated $3'{\rightarrow}5'$ proofreading exonuclease activity, which is consistent with its deduced amino acid sequence. PCR experiment with Par DNA polymerase showed an amplified product, indicating that this enzyme might be useful in DNA amplification and PCR-based applications.

This study compared obese children's food group intakes with the new Dietary References Intakes for Koreans (KDRIs) food guides for 5th-6th grade school children. This study also determined the extent of sedentary life styles related with obesity in this area of children. This is it cross-sectional study of 799 school children. The dietitian sent a survey form describing the project and a questionnaire to the subject's family. The questionnaire included child demographics, family history of chronic diseases, the daily servings of five food groups, such as grains, meat and beans, dairy products, fruits, and vegetables. The daily or weekly hours of physical activity, television viewing, and computer usage were also surveyed. Obesity index (%) of the subjects was calculated, and children with an obesity index (%) equal to or greater than 20 were classified as the obese. Among the 799 participants, 50.7% were female. The percentages of the normal and the obese were 691 (86.5%) and 108 (13.5%) respectively. Obese children reported eating less vegetables (p<0.05), more high sugar snacks (p<0.05), and high fat snacks (p<0.05) than normal children. No significant differences in food servings of grains, meats and beans, and fruits, and dairy products between the normal and the obese were shown. Obese children reported fewer hours of physical activities (p<0.05) and more hours of computer usage (p<0.05) than normal children. Girls showed less likelihood of being obese (odds ratio, 0.575, CI (0.38, 0.87), p<0.05). More hours of physical activity significantly decreased the likelihood of being obese (odds ratio, 0.572, CI (0.35, 0.92), p<0.05). Family history of obesity almost doubled the likelihood of obesity in children (odds ratio, 2.653, CI (1.660, 4.241), p<0.05). In conclusion, frequent snacking, inadequate vegetable consumption, and sedentary lifestyle increased significantly the likelihood of obesity in children, which suggest that obesity intervention in this age group should focuse more on those variables.

An agar-degrading bacterium was isolated from red seaweed (Gelidium amansii) on a natural seawater agar plate, and identified as Saccharophagus sp. AG21. The ${\beta}$-agarase gene from Saccharophagus sp. AG21 (agy1) was screened by long and accurate (LA)-PCR. The predicted sequence has a 1,908 bp open reading frame encoding 636 amino acids (aa), and includes a glycosyl hydrolase family 16 (GH16) ${\beta}$-agarase module and two carbohydrate binding modules of family 6 (CBM6). The deduced aa sequence showed 93.7% and 84.9% similarity to ${\beta}$-agarase of Saccharophagus degradans and Microbulbifer agarilyticus, respectively. The mature agy1 was cloned and overexpressed as a His-tagged recombinant ${\beta}$-agarase (rAgy1) in Escherichia coli, and had a predicted molecular mass of 69 kDa and an isoelectric point of 4.5. rAgy1 showed optimum activity at $55^{\circ}C$ and pH 7.6, and had a specific activity of 85 U/mg. The rAgy1 activity was enhanced by $FeSO_4$ (40%), KCl (34%), and NaCl (34%), compared with the control. The newly identified rAgy1 is a ${\beta}$-agarase, which acts to degrade agarose to neoagarotetraose (NA4) and neoagarohexaose (NA6) and may be useful for applications in the cosmetics, food, bioethanol, and reagent industries.

The Purpose of this study is to determine how Korean and United Sates families manage resourcese. Further, socioeconomic and social psychological determinants of frequency of family resoures management will be investigated for each country. Comparision of results well be made to find similarities and differences between Korea and the U.S. Most studies of family resource management have used urban samples, so this study adds to understanding of another segment of the populations. Family resource management variables, as dependent variables, were measured by asking respondents how often they used a variety of wasys to handle finances and time. Independent variables were : (a) total household income, (b) respondents education, (c) respondents ages, (d) householder size, (e) family adaptability, (f) family cohesion, and (g) interpersonal communications. Data for the Korean sample were collected in rural areas of South Korea during summer 1989, U.S. data were collected in two counties of Illinois. The data used in this study include 473 Korean samples and 301 U.S. families. In both samples, the respondent was the financial manager, the person who usually handled the finances and paid the bills. The data were analyzed by frequencys, t-test, and multiple regression analysis methods. As a results, U.S. respondents tended to engage in family resource management more frequently than Korean respondents. This could be attributed to a longer history of consumer education and financial management education taught in the public schools and through the Cooperative Extension Service in the U.S. Social-psycological variables were significant predictors of frequency of family financial management in both samples. the differences in both samples are that, in Korea, frequency of family financial management increased as household size and educational years increased, however, in the United States, the relationships of these variables were not significant. Some similarities and differences were found in Korea and the U.S. families, and this results represents that interpersonal communications are important determinants, even in different cultures. One hadn, the difference of socio-cultural factors result as the difference of some statisical differences. Findings from this study have important implications for research and education, and can be applicated to study of family resource management in other rural areas.

Purpose: This study was to explore family member's caregiving stress and satisfaction of care for patients with dementia in long term care facilities and day care centers. Methods: The subjects were 129 family members of elders with dementia from ten long term care facilities and eight day care centers in Daegu and Kyungsangbukdo. Data were collected from August to October, 2007. The instruments were self administered questionnaires and included. The Family Perceptions of Caregiving Role (FPCR) and the Family Perceptions of Care Tool (FPCT) which were developed by Maas and Buckwalter (1990) and translated by Park (2002). Results: Family member's care giving stress in day care centers were higher than that of long term care facilities (t=-2.89, p=.005) especially in the categories of captivity (t=-3.27, p=.001), guilty (t=-2.93, p=.004), and loss (t=-2.44, p=.016). Family member's satisfaction of care in day care centers was higher than that of long term care facilities (t=-3.21, p=.002) in the (use - categories or measures since you are referring to the instrument and delete aspects) aspects of effective management (t=-3.69, p=.000) and activity (t=-2.00, p=.045). Conclusion: The results of this study showed that family members' perceptions toward their care giving roles and satisfaction of care differ whether the facilities are long term care or day care centers. This study provides baseline data that could be used for improving the quality of long term care services.

This study aimed to explore the moderating effect of social support resources on the life satisfaction and caregiving burden of family caregivers taking care of the elderly in long-term care services. The study participants were selected from among the family caregivers utilizing 30 home care centers in Seoul, Korea. Of the candidates who agreed to participate in the study, 250 caregivers who had supported the elderly at home for at least 6 months were selected. The data collected were analyzed using SPSS ver. 21.0. The study findings were as follows. First, the whole family caregivers' caregiving burden of family caregivers was found to be slightly higher than the median value. More specifically, the physical burden was the heaviest, followed by the family relationship burden, the social activity burden, the emotional burden, and the financial burden. Social support resources and life satisfaction were found to be a little bit higher than the median value. Second, the variables that statistically significantly increased life satisfaction, starting with the strongest effect, were a lower psycho emotional burden, greater informational support resources, a lower economical burden, greater emotional support, a younger caregiver age, a higher monthly income, and a shorter care period. Third, informational support resources were found to have a moderating effect on the relationship between the support burden and life satisfaction. The more the participants used the informational support resource subcategory of the social support resources, the narrower the life satisfaction decrease, even though the caregivers felt a support burden. Informational support resources appear to have a statistically significant buffering effect.

This study examined job satisfaction and relevant variables for multi-cultural family home-visiting educators. The selected study subjects were 192 home-visiting educators who work at Multi-Cultural Family Support Centers in the Seoul, Gyeonggi-do, and Chungcheongnam-do areas. Data analysis was conducted using SPSS ver. 18.0. The main results were as follows. First, the job satisfaction level in multi-cultural family visiting educators stood at 3.29 points, subjects' age, averagely monthly income, marital status, and activity career were shown to influence generally upon job satisfaction, self-efficacy, job stress, and cultural competency. Job satisfaction was high in groups with: a high age, small career, low averagely monthly income, and married. Second, self-efficacy and job stress were big in the job satisfaction of multi-cultural family visiting educators. The same outcome as the existing prior research was indicated. Cultural competency was not significant. Third, an examination of relative influence upon job satisfaction in home visiting educators indicated that the explanation power was 29.0%. Significant influential variables included academic background, marital status, self-regulation, and role ambiguity. Self-regulation was greater for those with lower academic backgrounds and unmarried. Job satisfaction was higher in the lower role ambiguity. Thus, the same outcome as the existing prior research was indicated. Cultural competency wasn't indicated to be significant. This has significance in having shown characteristics of job satisfaction in multi-cultural family visiting educators.
