Activity theory explains that the old people participate in social activity as a role-substitute from loss of roles given by work and family. It is possible to enhance their life satisfaction through these activities. Based on this activity theory, this study aims at explore the role substitute of voluntary activities and to analysis whether volunteering commitment has an effect on life satisfaction. Data were collected by using survey questionnaires to the elderly over 55 years old who participated in voluntary activity at 25 Volunteer Centers in Seoul. The Activity theory was operationalized by job or joblessness, family type, achievement type obtained through voluntary activity The results are as follows. (1) Job or joblessness has effect on the activity frequence and activity time. (2) Social achievement after voluntary activity has effect on the duration only (3) And the family type did not have any effect. These three variables of activity theory do not have an effect on life satisfaction. The elderly volunteering commitment was explained by variables other than activity theory such as reward, health, education, sex. And the elderly volunteer's life satisfaction were affected by the family types and their economic status. These results imply that the Korean elderly voluntary activities could be expained partially by Activity theory. Also for these elder volunteers's life satisfaction, qualitative respects such as achievements through voluntary activity, and concerns and support by agencies are more important than the time they imput in voluntary activities.

Nanorod and particle shape $CeO_2$ were synthesized via hydrothermal process and precipitation method, respectively, and used as supports of Pt catalyst for water gas shift (WGS) reaction. Three different durations (12, 48, and 96h) for hydrothermal process were applied for the preparation of nanorod type $CeO_2$. 1.0 wt% of Pt was loaded on the prepared supports with incipient wetness method prior to the catalytic activity tests that were carried out at a GHSV of $95,541h^{-1}$, and a temperature range of 200 to $360^{\circ}C$. Varying duration of hydrothermal process led to the difference in physical characteristics of $CeO_2$ nanorods, such as aspect ratio, BET surface area, pore diameter, and pore volume. Consequently, the catalytic activities of Pt/$CeO_2$ nanorods were affected by the physical characteristics of the supports and appeared to be in the order of Pt/$CeO_2$(12) > Pt/$CeO_2$(48) > Pt/$CeO_2$(96). The comparison of the catalytic activities and results of the analysis (XPS, XRD, SEM, BET and TPR) for the supports revealed that the activity of the catalysts depends on chemical states of the Pt and the support materials in the temperature range that is lower than $280^{\circ}C$. However, the activity is rather dependent on the physical characteristic of the supports because the increased gas velocity limits the mass transfer of reactants in micropores of the supports.

Among many factors that affect the development of the talent of gifted children, the family factor that first finds and cultivates the talent of gifted children is quite important. The researches on the family of gifted children are mostly concentrated on physical environment out of the home environment, neglecting psychological environment. Although the recreational activity of family with gifted children considerably contributes to the emotional, intellectual and social development of gifted children themselves and to the improvement of life quality of the family members, the recreation of family with gifted children has not yet been studied. Thus, the objective of this research is to present basic materials for seeking the direction to educate parents and to support family with gifted children in order to encourage synergy effect in emotional and social growth of family with gifted children by surveying the property of recreation of family with gifted children. The result of result is as follows. First, the type of family with gifted children tends to be remarkably biased to 'family-oriented activity' and 'elf-development activity.' Second, verifying the significant level of motive for recreational activity of family with gifted children at the variables such as number of family members, parents' age, parents' education level, parents' occupation, etc, it was concluded that they were not statistically significant. The result of this research suggests that education and support for efficient recreation of family with gifted children is necessary to achieve healthy talent of gifted children.

This study aimed to suggest the tasks which public support groups should fundamentally perceive and develop support models based on it so that socioeconomic activities, which have been spreading in recent years, can settle in local communities. For this aim, this study was proceeded based on Gyeonggi Province, which has established socioeconomic support center at metropolitan councils and local government councils. The demands by Gyeonggi Province residents toward the policies by Ddabok communities and local community invigoration measures have been examined through demand survey. In the analysis, characteristics and support tasks of the demands have been identified based on the survey results and six support models have been developed according to the tasks. The derived tasks are overcoming low understanding of Ddabok communities, low participation in community activities, and poor will to perform socioeconomic practices and satisfying the demand toward community activity areas adjacent to residence. Furthermore, the differences with the residents who have an experience of taking part in the Ddabok Community Project have to be overcome. Based on these study findings, this study suggested that support models of integration style and differentiated style, response to demand style and customization to capability style, and resources-focused style and resources-scattered style are necessary in order for socioeconomic communities like Ddabok communities to settle in local communities.

As for the anti-terrorism bills, which were submitted to the National Assembly, the mobilization of anti-terrorism commando, which was designated or established by the National Defense Minister, is mobilized the military troops without being based on marital law in light of the constitutional law, thereby possibly violating the constitution, first of all, with regards to mobilization of anti-terrorism commando, which was formed with military troops. The anti-terrorism commando is the military force, which was trained professionally for the anti-terrorism activity. Thus, the violation of human rights may be greatly reduced rather than what general soldiers are putted in the public-order activity such as anti-terrorism. However, it is thought to be desirable to make it possible for the input of special forces, which were trained professionally in relation to anti-terrorism activity, through constitutionally revising the constitutional law. As for the provision of 'support for military troops' in the anti-terrorism bill, what is a case that the nation's important facilities and multi-use facilities are difficult to be protected from terror with the anti-terrorism commando and police force needs to be constitutionally regarded as resulting in reaching the level enough to correspond to 'a state of national emergency equivalent to wartime incident.' Thus, enacting the future anti-terrorism law, it is thought to be unnecessary for having the provision of 'support for military troops' with receiving criticism obstinately for possibly violating the constitution.

Al containing mesoporous molecular sieve (Al-MMS) was synthesized by hydrolysis of $H_2SiF_6$ and $Al(NO_3)_3{\cdot}9H_2O$. The material obtained was characterized by XRD, $N_2$-physisorption. The specific surface area was $981m^2/g$, and the average pore size was uniformity $39{\AA}$. It was confirmed that the acidity of Al-MMS was milder than that of zeolite Y based on the results of $NH_3$-TPD. Active materials, Pt and Pd, were loaded on Al-MMS in order to examine the feasibility of using Al-MMS as a catalyst support in the hydrogenation of aromatic compounds included in the residue oil of a naphtha cracker. The hydrogenation activity of PtPd/Al-MMS has been studied by following the kinetics of the hydrogenation of naphthalene, and by comparing the kinetic parameters obtained with Pt and Pd catalysts supported on the other mesoporous material support and commercial conventional support materials. PtPd/Al-MMS catalyst shows the highest activity of hydrogenation and sulfur resistance. The high activity of PtPd/Al-MMS was confirmed again in the hydrogenation of PGO (pyrolized gas oil), which is residue oil obtained from a naphtha cracker. Therefore, PtPd/Al-MMS can be applied to the hydrogenation of aromatic compounds included in the residue oil of a commercial naphtha cracker commericially.

The purpose of this study was to identify health promoting behaviors(HPBs) and the related determinants affecting to women workers health based on the New Health Promotion Model by Pender(1996). Data were collected by self-reported questionnaires from 208 women workers at the 8 electronic manufacturing factories under the permission of data collection and cooperation with health managers in the factories during the period from September to October 1999. For data analysis. Descriptive statistics, ANOVA, Pearson's correlation and Stepwise multiple regression with SPSS/PC+7.5 version were used. The results were as follows : 1. The average score for the HPBs, consisted of 6 subdimensions was 2.05. The highest mean score was 2.29 in 'Spiritual growth' and the lowest one was 1.66 in 'Physical activity'. 2. No significant difference between general charateristics and HPBs were found. 3. HPBs were positively related to 'Prior related behavior'(r=0.369, p<0.1), 'Perceived self-efficacy'(r=0.340, p<.01), 'Activity-related affect'(r=0.252, p<.01). 'Social support'(r=0.350, p<.01). 'Commitment to a plan action'(r=0.374, p<.01). There was no significant correlation between perceived health status, perceived barriers to action and HPBs. 4. The most important variable in HPBs was 'Commitment to a plan action'. It was explained 14.0% out of the total variance of HPBs. 'Commitment to a plan action', 'Prior related behavior', 'Social support', 'Self-efficacy' and 'Perceived barriers to action' explained 23.0%. According to the results of this study, the suggestions were as follows: 1. It is necessary to develop program for improving the physical activity and health responsibility of women workers at the manufacturing industry. 2. To facilitate and maintain HPBs of women workers, nurses may enhance and plan mutually interactive active HPBs with women workers. 3. Social support at the level of individual workers, supervisors, and the organization is required in order to conduct health promotion program at the factories. 4. Significantly related variables to HIPBs should be identified the direct and indirect paths among them further more.
