The purpose of this study is to develop human resources and management system model for home-based welfare services. For the purpose of the study, both of method of literature review about home-based welfare services and previous research and survey were used in the study. The subjects of the survey were Junior and senior high school students, the employed, housewives, the disabled, and the aged. They were considered as human resources for the home-based welfare services. Based on the result of the survey and related theories, the study suggests the model for the development of volunteers and management system composed of recruitment, education and training, disposition, management and supervision, and evaluation for home-based welfare services. Assuming linking and cooperation between volunteer center and agency using volunteers which provide home-based welfare services, the model was developed. The role of volunteer center is recruitment, education and training. The agency using volunteers is responsible for education, disposition, supervision, and evaluation related to practice. In the stage of recruitment, elaborating strategy considering characteristics of group was suggested. In the campaign, use of mass media, selection of timing, equal opportunity for all group were suggested. Also outreach strategy as a effective recruitment strategy was presented. In the stage of education and training, method and content of education in each stage of primary education and re-education were presented. In the stage disposition, method and content for the right volunteer in the right place were suggested. In the stage of management and supervision, supervision by coordinator and necessity of using volunteers as para-professionals was suggested. Also the necessity of program operation for volunteer maintenance and management was discussed. In the stage of evaluation, time, main body, and method of evaluation was suggested.

Objectives: The purpose of our study was to verify whether the Seven Emotions evaluated by Guibi-Tang questionnaire (GTQ) were predictive of self-awareness level of one's quality of life (QOL). Methods: Eighty volunteers participated in this study and completed the GTQ. In addition, the volunteers were asked to answer one's self-awareness of the QOL using numerical scale. Factor analysis was conducted for extraction of GTQ factors. Structural Equation Model (SEM) was conducted to verify path structure. Results: The estimates of the four factors on the level of one's QOL demonstrated that Chest Factor (=-0.330) showed the highest level of correlation followed by the seven emotions (=-0.213); Deficient fire (=0.141); and Qi Deficiency (=-0.023). Model fit is $X^2$=34.740 (df=36), GFI=0.931, AGFI=0.873, NFI=0.867, RFI=0.797, IFI=0.975, TLI=1.006, CFI=1.009, RMSEA=0.000. Therefore, considering these values, SEM could be accepted as a workable model. Conclusions: Our study results suggest that According to SEM, The Seven Emotions evaluated by GTQ are predictable for self-awareness of one's QOL.

The single cell gel electrophoresis (comet) assay is one of the useful tools for the study of genetic damage in humans exposed to environmental mutagens and carcinogens. This study was undertaken to evaluate the status of DNA damage in peripheral lymphocytes depending on their sex, age, smoking habits, and other factors in normal healthy Korean population. The 99 volunteers included in the study and out of these, 36 volunteers were smoker and 63 volunteers were non-smoker aged between 20-59 years. All individual answered a questionnaire that assessed their general information including smoking habits and the extent of the environmental tobacco smoke (ETS) exposure, and blood samples were obtained. There was a statistically significant difference in the extent of DNA damage between smoker and non-smoker (p<0.001). A significant difference was also observed between male and female (p<0.001) and amongst the different group of age (p<0.005), however, correlation analysis showed that only smoking habit was a significant factor for DNA damage. No significant effect of smoking duration, number of cigarettes smoking a day, SPY (smoke pack years) in smokers and environmental tobacco smoke exposure in non-smokers on the status of DNA damage was observed.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelves meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in twenty aged(TAG) and fifty aged(FAG) healthy volunteers groups when they were sleeping or awakening respectively, to do significance test for electric potential of meridian system among circadian rhythms(CR) and Sasang constitutions(SC). Methods : We selected who thirty healthy volunteers were diagnosed by a blood test, urine examination and differentiation of syndromes by five viscera among volunteers. When they were sleeping, their electric potentials of well and sea points in branches of the twelve meridians were simultaneously measured by physiograph. After a minute we measured them again, totally 5 times. And then when they were awakening, their electric potentials were measured 5 times by the above method. Results : Measurements were analyzed by statistical ANOVA test, we obtained that some of the electric potentials of TAG at sleeping significantly varied with CR, SC, and at awakening some of the electric potentials of FAG also significantly did with CR, SC.

Utilizing volunteers is one of the essential strategies to enhance and diversify the library service. especially in public libraries which have limited human resources. The purpose of this study is to explore a guideline which can be applied to recruit and manage volunteers in public libraries. To prepare a guideline. library volunteerism in foreign countries was discussed through the literature and the internet, and an empirical survey was conducted to analyze the volunteer management condition in 422 public libraries. Based on these surveys, a guideline composed of eight steps was recommended. This guideline can help libraries recruit, train, retain, and supervise volunteers in effective manner.

The purpose of this study was analyzed the factors of influencing toward attitude to death with dignity to hospice volunteers. The data was collected for 21 days from 14 March to 3 April 2010. Among a total of 220 cases of the questionaries, only 195 cases were used. To data were analyzed by factor analysis, independent t-test, one-way anova and logistic regression using PASW statistics 18.0. The results were as follows; The attitudes towards death with dignity according to general characteristics was high in those with will to agreed to the passive euthanasia than those opposite to the attitude factors, namely, acceptive, the right to decide, negative, and dereliction of duty attitude factors. Significant variables for effects of death with dignity were gender, acceptive attitude factor and dereliction of duty attitude factors. Given that main provider of human organs is the brain-dead and we don't have enough organ donation, death with dignity should be linked with activating policy of organ donation, while solving donation shortage problem. This way, constructing social implementation and sharing consciousness on organ donation, would be diluting the bio-ethic controversies.

A simple and specific method for determination of methyltestosterone (MT) has been established by a gas chromatography/mass selective detector and applied in plasma of healthy male volunteers received a single oral dose of 50 mg MT $(Testo^{TM}\;tablets,\;25\;mg)$ for bioavailability test. This method involves using liquid-liquid extraction of the sample with diethyl ether and derivatization with MSTFA. MT showed good resolution in this condition. The detection limit of quantitation was 5 ng/ml. A good linearity (r>0.996) was obtained at the range of 5-250 ng/ml of MT. Intra-day precision and accuracy were 2.76-12.56% and 0.39-8.01 %, and inter-day precision and accuracy were 2.29-17.69% and 0.42-7.99%, respectively. The established method was applied on bioavailability test of MT in human volunteers. The value of $AUC_{0\;to\;last}$ to last was $264.5{\pm}123.9\;ng{\cdot}hr/ml$ and that of $AUC_{0\;to\;inf}$ was determined to be $275.2{\pm}126.5\;ng{\cdot}hr/ml$. The values of $C_{max}$ and $T_{max}$ were $95.9{\pm}67.1\;ng/ml$ and $1.13{\pm}0.9\;hr$, respectively. The mean elimination half-life $(t_{1/2})$ was $4.4{\pm}0.9\;hr$. This analytical method is suitable and useful for the pharmacokinetics and bioequivalence studies of MT.

Objectives : There has been gradually increasing concern about the adverse health effects of electromagnetic radiation originating from cell phones which are widely used in modern life. Cell phone radiation may affect human health by increasing free radicals of human blood cells. This study has been designed to identify DNA damage of blood cells by electromagnetic radiation caused by cell phone use. Methods : This study investigated the health effect of acute exposure to commercially available cell phones on certain parameters such as an indicator of DNA damage for 14 healthy adult volunteers. Each volunteer during the experiment talked over the cell phone with the keypad facing the right side of the face for 4 hours. The single cell gel electrophoresis assay (Comet assay), which is very sensitive in detecting the presence of DNA strand-breaks and alkali-labile damage in individual cells, was used to assess peripheral blood cells (T-cells, B-cells, granulocytes) from volunteers before and after exposure to cell phone radiation. The parameters of Comet assay measured were Olive Tail Moment and Tail DNA %. Results : The Olive Tail Moment of B-cells and granulocytes and Tail DNA % of B-cells and granulocytes were increased by a statistically significant extent after 4-hour use of a cell phone compared with controls. Conclusion : It is concluded that cell phone radiation caused the DNA damage during the 4 hours of experimental condition. Nonetheless, this study suggested that cell phone use may increase DNA damage by electromagnetic radiation and other contributing factors.
