본 연구는 자원봉사동기와 사회자본 간의 관계에서 자원봉사활동만족도의 매개역할에 분석의 초점을 두었다. 분석자료는 진주시복지재단에 소속된1년 이상의 자원봉사자를 대상으로 실시한 설문조사이다. 최종분석수는 203 부이었고, 표집방법은 지역별 할당표집이다. 그리고 위계적 회귀분석 및Baron과 Kenny(1986)의 매개효과 검증을 활용하였다. 본 연구의 주요결과는 다음과 같다. 첫째, 타인지향 동기와 자기지향 동기모두 타인신뢰, 기관신뢰, 사회적 네트워크와 자원봉사활동만족도에 직접적으로 영향을 미치는 변수로 나타났다. 그리고 자원봉사활동만족도는 사회자본의 각 구성요소에 영향력이 가장 큰 변수로 나타났다. 둘째, 자원봉사활동만족도는 타인지향 동기와 타인신뢰, 기관신뢰 간에서는 부분매개역할을, 타인지향 동기와 사회적 네트워크의 관계에서는 완전매개역할을 수행하였다. 셋째, 자원봉사활동만족도는 자기지향동기와 타인신뢰, 그리고 사회적 네트워크와의 관계에서는 완전매개역할을, 자기지향동기와 기관신뢰의 관계에서는 부분매개역할을 수행하였다. 따라서 타인지향동기와 자기지향동기가자원봉사활동만족도를 통하여 사회자본에 미치는 영향의 경로가 다를 것이라는 가정은 일정부분 지지되었다고 할 것이다. 이러한 분석결과에 근거하여 사회적 자본의 증진을 위한 이론적, 실천적 논의가 제시되었다. The purpose of this study is to examine the relationship between motives of volunteers and social capital, focusing on the mediating effect of satisfaction in volunteers’activities. The data for analyses were collected from returned survey that had been sent to volunteers who were associated with jinjusi welfare foundations over 1 years. 203 questionnaires were analyzed finally and the sampling method is a regional quota sampling. This study utilizes hierarchical regression analysis and verification of the mediating effects of Baron and Kenny (1986). The main results of this study are as follows. First, the analysis shows that both altruistic and self-oriented motivations are significantly associated with other people s trust, institutional trust, social network and satisfaction in volunteers’activity. And the satisfaction in volunteers’activities is the most influential variable in explaining each component of social capital. Second, the satisfaction in volunteers’ activity plays the role of a partial mediating effect in the relation between altruistic motivation and trust for others and in the relation between altruistic motive and institutional trust, and plays the role of a complete mediating effect in the relationship between the altruistic motive and social network. Third, the satisfaction in volunteers’activity plays the role of a complete mediating effect in the relationship between self-oriented motivate and trust of others and in the relationship between self-oriented motive and social network, and plays a role of partial mediating effect in the relation between self-oriented motive and institutional trust. Therefore, it is partly verified that the paths of mediating effects of satisfaction in volunteers’ activity are different by motives of volunteer. Based on these analysis results, theoretical and practical implications for the promotion of social capital are suggested.

In 2005 as a part of a business supporting service of MOMAF, a study was accomplished on the chance of blended oil of MF30 to be used on fishing vessels with 3 kinds of pre-treatment facility models of Purifier, MCH and Purifier + MCH. The result of the study shows that MF30 blended oil, inspite of any kind of pretreatment applied, is possible to maintain the similar combustion state compared with MDO and save 30% of fuel cost as long as appropriate engine load, fuel temperature and filtering grade is kept according to users' manual. In a consequence of the study, fisheries industry afraid of increasing fuel cost demanded strongly additional research on limitation of using blended oil to the government. Therefore, in consideration by the government of the fisheries industry's situation, I comprised limitation of using blended oil, standard system of blended oil facilities, illegality of matter of giving off SOx, NOx and harmful exhaust gas in present regulation of international convention, development of simple fuel mixing equipment to reserve two kinds of fuel before being mixed in ship, installation expense of pre-treatment to compare with saving fuel cost following by using blending oil, shortened maintenance term and increasing the depreciation expense of engine, economical efficiency by analysis of total increased cost etc, under the name of the studies on the standardization for the system using blended oil in the fishing vessel through 2years of study based on policy of special research on fisheries from 2007 to 2008. I wish to describe here as it is summarized study-contents that related the title of this paper.

This study aims to gauge the applicability of autonomy‘s priciples to the process of community welfare planning with an emphasis on peoples who lack mental capacity, which means they have a need for a supported?decesion making in this article. In order to do this, first the present study established a framework and criteria for analyzing the contents of 4 community welfare plan. And then evaluated the level of autonomy with a selected indices. The fihdings revealed that social welfare service law, guidelines have the possibility of guiding the autonomy through using the term like dignity, happiness, self-determination, representation response, feedback. But any plans didn’t identify and meet the need of autonomy or for a suported decision-making, although the deliverative poll methods like FGI, reach-out presentation was used. To conclude, we can say that all the plans in analysis lack of the clarity and organization from the views of autonomy. Based on these results, we suggested a impoverishment strategy including the guidelines" upgrading, planner"s obligation, community welfare organization and community"s role respectively. This study was a first attempt to review and assess the community planning’s process and contents from autompmy’s perspectives.

강대선 ( Dae Sun Kang ),조수묵 ( Soo Muk Cho ),강희완 ( Hee Wan Kang ) 한국균학회 2012 韓國菌學會誌 Vol.40 No.4

효모추출물 4 mg/mL를 고추유묘에 경엽 및 뿌리 관주처리 24시간 후에 salicylic acid(SA)함량을 ultra high performance liquid chromatography(UHPLC)분석방법으로 측정한 결과 yeast cell wall extract(YCWE)처리구에서 대조구의 SA처리구와 동일한 peak가 검출되어 SA가생성 유도 되는 것으로 확인 되었다. SA는 YCWE를 경엽처리 48시간 후 20.29 ug/g으로 가장 높게 나타났으며 관주처리보다 약 3.7배의 높은 SA검출함량을 보였으나 처리 후 72시간부터는 점차적으로 SA함량이 감소하는 양상을 보였다. Yeast cell wall extract (YCWE) was treated on leaves and roots of pepper seedlings at the dosage of 4mg/mL and salicylic acid (SA) production in pepper was detected by ultra high performance liquid chromatography (UHPLC). The SA production in pepper stem was induced by YCWE. SA was produced at the highest level of 20.29ug/g after 48 hrs of foliar spray with YCWE, which is 3.7 times higher than that of root perfusion with YCWM. SA production was gradually reduced after 72 hrs of YCWE teatment.

지역사회복지관 지역조직화 프로그램의 임파워링에 대한 빈곤지역주민의 개별적 특성 차이에 관한 연구: 조직적 지역사회임파워먼트 영역(ODCE: Organizational Domains of Community Empowerment) 접근틀의 적용

강대선 ( Kang Dae Sun ) 한국보건사회연구원 2016 保健社會硏究 Vol.36 No.1

본 연구의 목적은 빈곤지역에 위치한 지역사회복지관 프로그램의 임파워링 특성이 빈곤지역주민의 성, 학력, 서비스이용기간, 거주기간의 차이에 따라 어떻게 판별되는지를 확인하는데 있다. 이를 위하여 Kasmel과 Tanggaard의 조직적 임파워먼트영역 접근틀(ODCE)을 지역사회복지관의 지역조직화 프로그램에 적용하였고, 단계적 판별분석을 실시하였다. 활용자료는 지역사회복지관의 지역조직화 프로그램에 참여하는 182명의 주민으로부터 수집되었다. 분석결과 첫째, 유의미한 판별함수는 성과 거주기간으로 나타났다. 그러나 거주기간에 따른 판별함수에는 임파워링특성 변인들이 유의미하지 못하였다. 둘째, 여성 주민과 남성 주민을 판별하는 유의미한 임파워링 변인은 지역사회유능성개발, 프로그램관리기술 특성이었고, 분류의 정확도는 62.1%이었다. 셋째, 지역조직화 프로그램의 참여여성들은 의사결정에 필요한 정보를 획득하는 경험에서, 이에 반하여 남성주민들은 프로그램의 실제운영과 관련한 기술습득에서 임파워링 경험을 더 인식하는 것으로 나타났다. 이러한 연구결과에 기반하여 이론적, 실천적 함의가 제시되었다. The purpose of this study is to identify how the community organizing program`s empowering characteristics discriminate the poor-area resident`s individual characteristics like gender, education, service use duration, and residency time. For this, the author applied the Kasmel & Tanggaard`s Organizational Domains of Community Empowerment (ODCE) approach framework to the community organizing program of community welfare centers and employed stepwise discriminant analysis, using data collected from 182 residents participating in community organizing programs. The findings are as follows: Firstly, gender and residency time were found to be significant discriminant variables. In the discriminant functions of residency time, however, there was no significant empowering variable. Secondly, the empowering variables which discriminated significantly between the male and female residents were community competence and program management skills, with an overall correct classification percentage of 62.1%. Thirdly, female residents perceived more empowering experience in acquiring information necessary for decision-making, while, male perceived more in acquiring skills relevant to the actual operation of the programs.

빈곤지역 주민의 지역사회임파워먼트와 지역사회실천가의 역할

강대선(Dae-Sun Kang) 충남대학교 사회과학연구소 2015 사회과학연구 Vol.26 No.1

This study has a double purpose: to identify the relationship between the community practitioner’s roles and community empowerment empirically, and to examine the moderating effects of the personal and residency characteristics including the service usage duration in these relationships. To do this, this study employed the factor reduction analysis, multiple regression analysis and moderating regression method. The findings revealed as follows: First, the result of factor analysis indicated that the practitioner’s roles classified into 7 ones like the educator/trainer for the community competency, the social actionist for social formation, the technocracy-driven advocate for community benefits, enabler, mediator, broker for resource acquisition. Second, the advocate and educator/trainer’s role influenced on the community empowerment significantly and positively. And the colleague’s role had a positive relation with the civic awareness significantly, but the broker’s role affected negatively. In the sense of membership, the educator/trainer and the mediator’s roles affected positively, but the enabler had a negative impact. Third, sex acted as moderators in connecting with the actionist(-) in case of the empowerment, and also as moderator in connecting with the colleague(+) in case of the sense of membership. Fourth, the length of residency acted as a moderator in connecting with advocate(+) on the sense of membership. Based on these results, theoretical and practical implications involving the improvement strategy for the practitioner’s roles in the empowerment intervention were suggested.

강대선(Dae-Sun Kang),오영란(Young-Ran Oh),조혜정(Hye-Chung Cho),김혜정(Hye-Jung Kim) 한국NGO학회 2021 NGO연구 Vol.16 No.2

본 연구는 선행연구에 근거하여 외로움과 이에 영향을 미치는 다양한 요소 간의 관계를 성인기 연령집단별로 확인하였다. 이러한 연구목적을 충족하기 위하여 부산시민을 대상으로 한 설문 조사에 기초하여 위계적 회귀 분석모형을 활용하였다. 분석결과 첫째, 첫째, 60대 이상의 노년기가 타 연령집단보다 외로움의 수준이 상대적으로 가장 높았다. 둘째, 다른 모든 변수를 통제하였을 때, 사회관계의 영향력은 20-30대 8.4%, 40-50대 15.8%, 60대 이상 19.2% 순으로 나타났다. 즉, 연령대가 높아질수록 사회관계 요인이 외로움에 미치는 영향력이 점점 커지는 것으로 나타났다. 셋째, 20-30대는 온라인 관계가 60대 이상은 오프라인 관계가 중요하게 영향을 미치는 것으로 나타났다. 그리고 40-50대의 경우 가족을 중심으로 한 관계밀도가 더 중요하였다. 이 같은 분석결과에 근거하여 이론적, 실천적 논의와 제안이 제시되었다. The aim of this study identified the relationship between loneliness and its various influencing factors, derived from previous research, by age group in adulthood. To meet the purpose of this study, a hierarchical regression analysis model was used based on a survey of Busan citizens. The results show that firstly, the old over 60 was the highest level of loneliness relatively compared with other age groups. Secondly, when controlling all other variables, the influence of social relations was followed: 20-30 group 8.4%, 40-50 group 15.8, over 60 groups 15.8%. Therefore as the age increases, social relation factors’ influence on loneliness would increase. Thirdly, online social relations were more important in the 20-30 group and offline relationships over 60 group but, the relationship density between family members was more important in the 40-50 group. Based on these results, we suggested theoretical, practical discussions and recommendations.
