불우이웃결연사업 후원만족도에 관한 연구 : 한국복지재단 결연후원자 중심으로

임신혁 한림대학교 사회복지대학원 2001 국내석사

사회복지 기관들의 재정에 대한 문제는 공통적인 과제로 끊임없이 논의되어 왔다. 따라서 자원을 동원하기 위한 다양한 방법을 시도하여 왔다. 이러한 자원동원의 여러 방법중 소외계층에 대한 경제적, 정서적 지원프로그램으로 사회적 관심과 자원동원의 성과를 거두고 있는 불우이웃 결연사업에 대하여 효율적인 운영을 알아보는 것도 매우 중요하다고 할 수 있다. 불우이웃 결연사업은 경제적, 정서적으로 꾸준한 지원을 통하여 아동의 성장과 저소득층의 경제적 자립을 목적으로 하고 있으나 높은 후원중단율로 인해 결연사업의 독특한 효과성을 이루지 못하는 것은 물론 신규 자원개발에도 큰 장애요인이 되고 있다. 더욱이 결연후원의 도움이 준비 없이 중단되어 경제적 정서적 아픔을 겪는 결연자에 대한 대책이 전혀 없는 상태이다. 이러한 문제를 후원자의 후원참여 만족도를 통해 알아보고 앞으로 최소화 할 수 있는 기관의 노력이 절대적으로 필요한 시기이다. 국내에서 불우이웃 결연사업을 가장 폭 넓게 수행하고 있는 한국복지재단의 후원자를 대상으로 개인적인 특성, 결연자와의 교류관계, 후원활동 내용, 기관의 신뢰도에 따라 불우이웃 결연사업의 후원만족을 어떠한 형태로 느끼고 있는지를 알아보고 이를 통해 기존의 후원자들에게는 후원의 지속성을 높이고 새로운 자원개발 전략을 위한 방향성을 제시하고자 한다. 조사도구로는 구조화된 설문지를 이용하였다. 연구대상은 한국복지재단 후원자 500명을 대상으로 하였다. 이들에게 설문지를 우편으로 발송하여 275부가 회수되어 최종자료로 사용되었다. 자료분석은 SPSS. Ver.10 통계분석 프로그램을 이용하여 빈도분석, 백분율과 같은 기술적 통계방법과 T 검증과 ANOVA 검증 및 상관분석을 사용하였다. 연구결과를 요약하면 다음과 같다. 개인적인 특성과 만족도와의 관계를 보면 종교의 유무, 후원내용에 대하여 가족의 인지여부, 주변사람에게 후원권유여부가 통계적으로 유의한 차이를 타나냈으며, 단계별 후원만족도 부분에서는 사회적 의무수행만족도에 결연여부, 종교유무, 직업, 가족인지, 타기관 후원여부의 요인과 자아실현 만족도에 결혼여부, 종교유무, 가족인지, 후원권유의 요인이 통계적으로 유의한 차이를 보였다. 둘째, 결연자와의 교류관계(서신, 만남, 선물전달)와 만족도와의 관계를 분석한 결과 유의한 차이를 보이는 요인은 없었다. 단계별 후원만족도 부분에는 자아실현 만족도에 만남 요인이 유의한 차이를 보였다. 셋째, 후원활동 내용과 후원만족도와의 관계를 분석한 결과 후원신청 동기가 유의한 차이를 보였으며, 단계적 후원만족도 부분에는 사회적 의무수행 만족도에 후원신청경로, 후원기간의 요인이, 사회적 존경만족도에 후원신청동기, 후원신청경로요인이 유의한 차이를 보이고 있었다. 넷째, 기관의 신뢰도와 후원만족도와의 관계를 살펴보면 기관의 결연자관리, 후원자관리, 후원금관리, 결연관리, 대외홍보관리업무 영역과 단계별 후원만족도와 대부분에서 상관관계가 있는 것으로 확인되어 기관에서는 업무의 투명성과 신뢰성을 확보하는 것이 무엇보다도 중요하다고 하겠다. 이와 같은 연구결과를 통해 다음과 같은 함의를 얻을 수 있었다. 먼저, 결연사업의 특징적인 효과를 얻지 못하고 결연과 중단이 악순환되는 현실속에서 기관에서 제공하는 형식적인 서비스가 후원자들의 만족도에 영향을 주지 못하는 것으로 나타났다. 따라서 결연기관에서는 정서적인 교류가 이루어 질 수 있는 프로그램 개발에 많은 노력이 필요함을 알 수 있었다. 두 번째로, 대부분 후원자 중심으로 이루지는 연구들에 비하여, 결연사업에 주체인 결연대상자에 대한 연구가 조속히 이루어져야 할 것이다. 세 번째로, 후원자의 가족 및 주변사람들의 행동이 후원만족도에 많은 영향을 주는 것으로 나타났다. 전문적인 후원자 관리 프로그램을 통해 후원자 주변의 자원을 결집시켜 후원에 참여 할 수 있도록 하는 실천적 전략 노력이 필요하다. 마지막으로 기관의 업무 신뢰도 확보는 사회적 의무감에서 스스로 참여하는 다양한 자원을 확보할 수 있으며, 끊임없는 사회적 관심을 유도 할 수 있음을 느낄 수 있었다. There has been great deal of discussion about the financial problem of social welfare facilities as a common issue and various solution of getting financial support has been attempted. Among the various way of getting financial support, It is very important to notice efficient management of the campaign to help needy neighbors, that is economical and emotional support program for the people from alienated level of society, is getting results of financial support and social concern. This campaign aims for growth of children and financial independence of the lower income bracket through the steady economic and emotional support, but the high discontinuance rate of these support makes the campaign fruitless and also is in the way of developing new financial resources. Moreover, there is absolutely no policy for the unfortunate neighbors who suffer from both emotional and financial difficulty arise from sudden discontinuance of support. So it is now strongly required that concerned facilities should resolve this problem(at least try to do something to minimize) by checking the level of satisfaction the supporter feels when they participate in these kind of campaign. We studied the level of satisfaction of supporters who are supporting Korean welfare foundation by asking them if certain factors affects their satisfaction level they feel from participating in backing campaign. (these factors includes personal characteristics, relationship with people being supported, the contents of supporting activity and confidence in concerned facility). By doing this, we can reinforce the durability of support they give and come up with direction needed to set up new strategy for new resource development. Structural question was used for investigation and conducted questionnaire survey of 500 peoples who supports Korean welfare foundation. Questions were sent to their addresses via mail service and 275 of them were returned and used as final data. Data was analyzed by technical statistical method such as frequency analysis and percentage and T verification, ANOVA verification and correlative analysis using SPSS Ver 10 statistical analysis program. The results can be summarized as follows. Frist, As for the relation between personal characteristics and satisfaction level, there are significant difference depends on religion, family's knowledge of the contents of supporting activity and the fact if they encourage others to join in. Regarding the satisfaction level by stage, satisfaction from social performance of duty showed noticeable difference depends on religion, job, family's knowledge and if they participate in other welfare facilities and for the satisfaction from self realization, there are statistical difference based on marriage, religion, family's knowledge and the fact if they encourage others to join in. Second, after investigating the relationship between satisfaction level and the relation with people being supported(letter,meeting,exchanging gift), there was no significant difference based on it. But there are noticeable difference based on meeting in satisfaction from self realization. Third, after studying the relationship between the contents of supporting activity and satisfaction from supporting, there are difference based on the motive of applying for support. As for the satisfaction from supporting, there are difference based on the process of applying support and the period support, for the satisfaction from social respect, the motive of applying supprt and the process of applying support showed difference in this criteria. Fourth, after the investigation of relationship between confidence in concerned facility and satisfaction from supporting, there was correlation between the satisfaction from supporting by stage and the management of supporter, people being supported, fund, publicity activity by concerned facility, which means concerned facilities should try to secure fairness and confidence in their task. From the above study, following conclusions could be induced. First, in the present fruitless situation, which repeats vicious circle of forming relation and discontinuance, the formal service provided by welfare facility does not affects the satisfaction level of most supporters. Thus, it is advised that concerned facilities should try to create program useful for emotional exchange. Second, many research have been performed emphasizing the importance of supporters, so it is required that follow up should be focused on facilities, that is the main body of this scheme. Third, the behavior of supporter's family and surrounding acquaintance found to be influential in satisfaction level from supporting. So, practical strategy is needed to encourage surrounding resources to participate in supporter's group by special management program for supporters. Finally, concerned facility's effort of securing trust in their task enables security of voluntary resources of many kinds and also can keep arousing ceaseless public attention on this issue.

Microwave oscillators stabilized to a coherent population trapping resonance

임신혁 Graduate School, Korea University 2012 국내박사

In this thesis, productions of the stable microwave oscillators using an extended-cavity diode laser (ECDL) in multimode operation are studied and realized. While in most spectroscopic experiments multimode operation of a laser is not desirable, we intentionally choose operating parameters so that the ECDL produces three modes. An ECDL is a composite-cavity system consisting of a laser diode and an external grating so that it is prone to multimode operation. In addition, the beat frequency between a pair of modes depends sensitively on either injection current to the laser or a piezoelectric transducer (PZT) voltage applied to a PZT attached to an external grating. It allows the beat frequency to be fine tuned by a feedback system and presents the possibility to make a stable microwave oscillator based on an ECDL without using an external local oscillator. In order to confirm the dynamics of the ECDL in multimode operation, we use a saturated absorption spectrometer and a confocal spectrum analyzer as the optical monitoring systems. A microwave spectrum analyzer and a frequency counter are also used for the microwave monitoring systems. After forcing the ECDL to mul- timode operation, we lock the phase of the two modes from an ECDL to a stable synthesizer. In this experiment we use a conventional phase lock method. Allan deviation of the beat frequency, when the two modes are phase-locked, drops as an inverse of the measurement time and it reaches 10^−14 when the time is 1 h. We also lock the phase of the two modes with reference to a dispersion signal from a coherent population trapping (CPT) resonance of 85Rb at 3.036 GHz. We measure the dispersion from the CPT by comparing the phases of the 3.036 GHz beat signals before and after the Rb cell. This experiment is in principle free from an external oscillator and a modulator and it is significant simplification over a conventional CPT-based atomic clock. Allan deviation of the beat frequency is 1 *10^−10 at 200 s integration time. In addition, we use an optoelectronic oscillator (OEO), which is stabilized to an intra-loop 85Rb cell with a 3.036 GHz CPT resonance. Our OEO design employs direct modulation of an injection current to an ECDL. In this experiment, the CPT resonance plays the role of a narrow optical band-pass filter. Long-term Allan deviation of the OEO frequency approaches 2*10−9. To further study the effect of the CPT resonance in the OEO loop, we measured induced frequency shift of the OEO as its loop length is changed. We construct a set of a corner cube retroreflector with a PZT which is calibrated by using a Mach-Zehnder interferometer. In a simple OEO, the loop length is 27 m which corresponds to a free spectral range of 11 MHz and an induced frequency shift is 111.8 Hz/um. When frequency of the OEO is on the CPT resonance, however, an induced frequency shift is changed to 0.130 Hz/um which corresponds to an effective loop length of 23.1 km.
