  • Purpose: This event related fMRI study was to further our understanding about how different brain regions could contribute to effective access of specific information stored in long term memory. This experiment has allowed us to determine the brain regions involved in recognition of familiar faces among non familiar faces. Materials and Methods: Twelve right handed normal, healthy volunteer adults participated in face recognition experiment. The paradigm consists of two 40 familiar faces, 40 unfamiliar faces and control base with scrambled faces in a randomized order, with null events. Volunteers were instructed to press on one of two possible buttons of a response box to indicate whether a face was familiar or not. Incorrect answers were ignored. A 1.5T MRI system(GMENS) was employed to evaluate brain activity by using blood oxygen level dependent (BOLD) contrast. Gradient Echo EPI sequence with TR/TE= 2250/40 msec was used for 17 contiguous axial slices of 7mm thickness, covering the whole brain volume (240mm Field of view, 64 ${\times}$ 64 in plane resolution). The acquired data were applied to SPM99 for the processing such as realignment, normalization, smoothing, statistical ANOVA and statistical preference. Results/Disscusion: The comparison of familiar faces vs unfamiliar faces yielded significant activations in the medial temporal regions, the occipito temporal regions and in frontal regions. These results suggest that when volunteers are asked to recognize familiar faces among unfamiliar faces they tend to activate several regions frequently involved in face perception. The medial temporal regions are also activated for familiar and unfamiliar faces. This interesting result suggests a contribution of this structure in the attempt to match perceived faces with pre existing semantic representations stored in long term memory.

  • The genetically determined CYP2D6 activity as considered to be associated with cancer susceptibility with inter-individual variation. Genetic polymorphism of CYP2D6(B) and CYP2D6(T) was determined by the two polymerase chain reaction(PCR) and BstN1 and EcoN1 restriction fragment length polymorphisms(RFLP) for 67 lung cancer cases and 95 healthy volunteer controls. The cases were composed of 26 squamous cell carcinoma, 14 small cell carcinoma, 10 adenocarcinoma, 3 large cell undifferentiated carcinoma, and 14 not histologically diagnosed. The results were gained from the 142 subjects (57 cases and 85 controls) who observed successfully in two PCR and BstNl/EcoN1 RELP. Only one and no mutant allele of the CYP2D6(B) and CYP2D6(T) gene was detected, that is, the frequency of mutant allele was very low; 0.7%(1/142) and 0%(0/142), respectively. Detected mutant allele of the CYP2D6(B) was beterozygous type(WM). The odds ratios for lung cancer susceptibility with CYP2D6(B) and CYP2D6(T) genotype were not calculated. These results are similar to the previous understanding that the mutant allele is very rare in Orientals compared to Caucasians, therefore, it considered that CYP2D6(B) and CYP2D6(T) genotypes have maybe no association with lung cancer susceptibility in Koreans. This is the basic data of CYP2D6(B) and CYP2D6(T) genotypes for Koreans. It would be hepful for further study to determine lung cancer susceptibility of Koreans with the data about CYP1A1, CYP2E1, GSTM1 from future study.

  • It a very important part to keep a good relationship with supporters to promote the activities smoothly in non-profit-making organizations. The donation, a financial source of non-profit-making organizations, and the volunteer activities of supporters are also born from the identity with the supportive organizations. This research is a study about the relationship sustainability with supporters and supportive organizations, which is practiced with the variables of image, service quality, ethics, activity, satisfaction, trust, and intent of sustaining their support of supportive organizations. This research aims at making the model of relationship-sustaining intent of supporters and supportive organizations on the bass of the relationship between the conceptual definition about supportive activities and the variables influencing the supportive activities, and at suggesting the marketing points of non-profit-making organizations on the base of the model. This is because the concept of service quality about non-profit-making organizations has not been formed yet, and so it does not influence the trust or the satisfaction. Other assumptions seemed to have some relationship. As a result, in order to increase the intent of sustaining support and the trust in organizations, they need to inform supporters of the image or the results of activities by means of active marketing activities.

  • Community Service Order is a program that holds a significant place in the system of probation. With its important role in the probation, there is an equally high expectation of the intervention from the program among the people which it serves. The problem lies in that people's understanding of the program is minimized to merely a volunteer-based social activity, which cause a division on how the program is to be run. The purpose of this research is to come up with a method that can efficiently organize the administrative plan to maximize its potentiality of the program. To adopt such a plan, "Sentencing to Service," an effective community service order program in Minnesota, U. S. A. was examined. An interview with the administrative staff, as well as a survey, using systematic sampling, with the participants was conducted to study the effective process and intervention of the program that has existed for fifteen years. The result concluded that "Sentencing to Service" is a successful program with the components of success being that of a positive support from the local community and high motivation level of the participants. In order for the program to be a positive experience for the participants, it is highly contingent upon the crew leaders. On the basis of the research findings, the following suggestions are made. First, a structured guideline for those who are involved in the program is necessary. Second, thorough training provided for the crew leaders are required and a social worker is recommended for the position of crew leader. Lastly, Community Service Order should not widen the net, but ought to serve as an alternative to incarceration.

  • The 40-hour work week system has brought positive impact on shortening working hours, eliminating long-time work, increasing leisure-time with family, etc. And this has brought about an increase in leisure-life satisfaction and happiness level. The type of leisure activities has changed from passive activities such as rest to active activities such as sports, tourism. And the 40-hour work week system has positive impact on social activities such as participation in volunteer work and, club activities. Thus all efforts need to be made to establish 40-hour work week system as soon as possible in all workplace. Firstly, 40-hour work week system needs to be introduced to every workplace with less than 5 persons, enlarge 5-day school week system into every primary and secondary school, and create conditions for positive leisure activities. Secondly, labor standards supervision and administration needs to be strengthened to eliminate long-time work over 52 hours per week, below-minimum wage work.

  • One of the current issues in Workers' Compensation Insurance is about the coverage range. Korea uses the definition of worker under the Labor Standards Act in Workers' Compensation Act and solved the problems associated with the coverage range of insurance group by the exceptional clause only for the groups which was raised about the need for the social protection. The purpose of this paper is to draw implications for solving problems which are associated with the coverage range of insurance group by reviewing the German literature. We focus on volunteers and persons in special types of employment. German government supports the activity of volunteers by providing with the protection service against the accidents. This paper shows how the coverage range is extended from the dependent employees in the introduction of the Workers' Compensation Insurance to the people who need social protection focusing on the volunteers. The implications of this research are following. First, German system shows that Workers' Compensation Insurance can be extended to the groups which do not belong to the dependent employee but are worthy of protection. Second, it is necessary to provide volunteers in the social welfare system with the protection service against the accidents and the statutory accident scheme is recommendable to use. Third, volunteers in the social welfare system need to be compulsory insured. Fourth, Korea should find their own way in solving problems associated with persons in special types of employment.

  • This study examined the effects of social capital on psychological identity and practical wellbeing for the Korean baby boom generation. To achieve this, an empirical survey was carried out on baby boomers who use elderly welfare centers and cultural centers living in D City. The overall research results showed that trust (t=6.893, p<.05), participation (t=5.157, p<.05), network (t=8.093, p<.05), and norm and reciprocity (t=4.787, p<.05), as sub-factors of social capital for baby boomers, had a significant effect on their practical wellbeing. Psychological identity was moderated (t=2.023, p<.05) in the effect of trust on practical wellbeing, adopting the hypothesis. This means that the social ties and the strong trust relationship between family members and relatives, which built up amid rapid economic growth, work with positive expectations of social capital and have a major effect on practical wellbeing. Moreover, practical welling also rated high, along with the high trust relationship and psychological identity. Consequently, various exchange programs and group and volunteer activity programs for baby boomers should be established to decrease their psychological identity due to the loss of social roles. Moreover, the decline of activities at a time of retirement can slow practical wellbeing.

  • Recently, urban parks are required to actively participate with residents in order to strengthen social functions and maintain sustainable management. This study analyzed the formation process of volunteer resident groups (Chamsamo) in the neighborhood parks in which local residents can participate in an ongoing basis based on the solidarity of a daily living space. The important factors in the activation of resident activity are derived from 5 aspects including resources, local area, resident group capacity, resident group role, and public support. The results of the study are as follows. 1) Life-friendly resources: It was important to find life-friendly resources such as 'Chamsaem' in the park. The combined resources of continuous human activities provided various benefits to the residents. This has led to stronger attachment and community activities to continue to utilize attractive resources in the park. 2) Sharing Common Daily Spaces and Expansion: As the Chamsamo activities were centered around the neighborhood, the network of activists in the local community expanded. This led to continued resident interest and favorable participation as well as to the regional expansion of Chamsamo activities. 3) Park management as part of everyday life: Park management became a part of everyday life, and pleasant park management was facilitated by utilizing the talents of the residents, who carried out diverse activities and constantly streamlined their hard labor. 4) Chamsamo's Leadership Linking Residents and the Public Sector through Leading Park Management Activities: Chamsamo served as a middle leader in linking the public sector and its users. 5) Role and Support of the Public Sector: In order to be able to sustain the activities of residents, the government's willingness to support the resident-led activities of the park in planning and operating the public sector was required. In the public management system of the park, support for residents' activities such as financing, education, and consulting was necessary.

  • Objectives : To evaluate the effects of Head Acupuncture versus Upper and Lower Limbs Acupuncture on signal activation of Blood Oxygen Level Dependent(BOLD) fMRI on the Brain and Somatosensory Cortex. Subjects and Methods : 10 healthy normal right-handed female volunteer were recruited. The average age of the 10 subjects was 30 years old. The BOLD functional MRI(fMRI) signal characteristics were determined during tactile stimulation was conducted by rubbing 4 acu-points in the right upper and lower limbs($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$). After stimulation of Head Acupuncture in Sishencong($HN_1$), $GB_{18}$, $GB_9$, $TH_{20}$ of Left versus Upper and Lower Limbs Acupuncture($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$ of Right) and took off needles. Then the BOLD fMRI signal characteristics were determined at the same manner. Results : 1. When touched with cotton buds(sensory stimulation), left Parietal Lobe, Post-central Gyrus, primary somatosensory cortex(BA 1, 2, 3), and primary motor cortex(BA 4) were mainly activated. When $ST_{36}$ was stimulated, Frontal Lobe, Parietal Lobe, Cerebellum, and Posterior Lobe as well as Inter-Hemispheric displaying a variety of regions. 2. In signal activation before and after Head Acupuncture reaction, it showed signal activation after removing the acupuncture needle and right Somatosensory Association Cortex, Postcentral Gyrus, and Parietal Lobe were more activated. 3. In reactions of before and after Upper and Lower Limb Acupuncture, it also showed signal activation after removing the acupuncture needle and bilateral Occipital Lobe, Lingual Gyrus, visual association cortex, and Cerebellum were activated. 4. After acupuncture stimulation, In Upper and Lower Limb Acupuncture Group, left frontal Lobe, Precentral Gyrus and Bilateral parietal lobe, Postcentral Gyrus and Primary Somatosensory Cortex(BA 2) were activated. In Head Acupuncture Group, which has most similar activation regions, but especially right Pre-Post central Gyrus, Primary Somatosensory Cortex(BA 3), Primary Motor Cortex, frontal Lobe and Parietal Lobe were activated. Conclusions : When sensory stimulation was done with cotton buds on four acup-points($LI_1$, $LI_{10}4, $LV_3$, $ST_{36}$), while bilaterally activated, contralateral sense was more dominant. It showed consistency with cerebral cortex function. When $ST_{36}$ was stimulated Frontal Lobe, Parietal Lobe, Cerebellum, Posterior Lobe as well as Inter-Hemispheric were stimulated. In Head Acupuncture, it showed more contralateral activation after acupuncture. In Upper and Lower Limb Acupuncture, it showed typically contralateral activation and deactivation of limbic system after acupuncture stimulation. Therefore, there were different fMRI BOLD signal activation reaction before and after Head Acupuncture vs Upper and Lower Limb Acupuncture which might be thought to be caused by acu-points' sensitivity and different sensory receptor to response acupuncture stimulation.
