This study aims to analyze the performance of public-private governance of urban parks in Cheongju-city, focusing on the 'cooperative governance' model of Ansell & Gash(2007) and find implications. The performance and limitations of the governance were analyzed using 13 success factors suggested by this model. According to the results of the analysis, four categories are satisfied: initial conditions, institutional design, leadership, and cooperation process. 8 out of 13 factors were analyzed at a 'good' level and thus this governance can be evaluated as successful one. Building trust and committed collaboration can be seen as key elements of successful governance. On the other hand, 5 factors were evaluated as 'average' because some limitations were revealed. The results of this analysis suggests that in order to improve cooperative governance, a post-implementation management system should prepared, and the inclusiveness of participation should further strengthened, and also regulations that ensure a regular forum for indirect participants and the public from the institutional design stage should be established. Although this study was analyzed based on the evaluation category of the objectively verified model, there is a limitation in that the evaluation was based on subjective judgment.

The main purpose of this paper is to understand the process of the poverty exit across generations through the live experience based on the grounded theory analysis of the in-depth interview. We find that poverty means a lack of achievement and freedom of agency that is a level of control about resource and situation. So exit of poverty across generations is the state that is not only to achieve functioning but also to recover capabilities. Based on this result, central phenomena of the intergenerational exit process of poverty are support from relation and continuous transition at each stage in life. Even if this central phenomenon is an important event, it has the incomplete attribute. Because support from relation is beyond individual scope of control and participants can't escape second labor market as they don't have enough time in the process of transition. Therefore, this paper suggests that the expansion of state welfare and strategy should support transition as policy priorities to minimize limitation of relation and risk of income loss.

In this paper, design parameters of dynamic vibration absorber, which is used to reduce bending vibrations of a vehicle drive line, is optimized. For obtaining the correct dynamic response characteristics, a flexible-body drive line is made by applying the flexibility data extracted from vibration analysis of propeller shafts to the drive line dynamic model. Inner tube mass, rubber stiffness and rubber damping coefficient of the dynamic vibration absorber are taken as design parameters for optimization. To minimize the vertical acceleration of the drive line, a second-order regression equation of the objective function is generated by performing the central composite experimental design with 3 factors, 2 levels and 15 test runs. And the design parameters of the dynamic vibration absorber are determined by using optimization program. The vehicle model with optimized dynamic vibration absorber reduces the vertical acceleration peak of the drive line by 17.1 % in compared with the initial model.

이 글의 목적은 피터 메리만과 린 피어스가 편집한 <모빌리티와 인문학(Mobilities and the Humanities)>을 중심으로 '새 모빌리티 패러다임'과 그에 기초한 영상 및 문학 텍스트의 연구 사례들을 살펴보고, 그것들이 텍스트 연구 방법으로서 갖는 의의를 검토함으로써 모빌리티 텍스트 연구 방법을 모색하는 데 있다. <모빌리티와 인문학>은 '인문학'이라는 제목과 달리 대부분 문학 및 영상 텍스트와 그 미학을 다루는 논문들로 구성되어 있다. 이 글은 이 책에 실린 논문들을 자동차 모빌리티 시스템에 집중하는 논문들과 그렇지 않은 논문들로 구분해서 다룬다. 자동차 시스템은 오늘날 모빌리티를 상징적으로 보여주는 기계로서 과거 철도가 근대 초기 보유했던 것만큼 커다란 사회적·문화적 의의를 지니고 있기 때문이다. 우선, 자동차 모빌리티에 초점을 맞추는 논문들은 주로 모빌리티 시스템과 영상·문학 텍스트의 공진화 양상을 탐구한다. 여기서는 자동차 모빌리티 시스템과 로드무비 장르의 내적 상호작용, 일종의 텍스트로서 미디어화된 자동차 모빌리티, 여행소설과 '마비된 모빌리티'의 텍스트적 재현, 개별 자동차 여행의 특이성과 '기술적 무의식' 등의 문제를 다룬다. 그 외의 논문들은 모빌리티와 예술 형식의 관계를 중심으로 형식의 모빌리티 또는 모빌리티의 재현 문제를 탐구한다. '형식의 모빌리티' 또는 '이동하는 예술 형식', 리얼리즘적 재현을 통한 이동하는 세계에서의 '느린 장소 감각'(애착감, 친근감) 형성, 문학 텍스트의 '소급적 특징'에 기초한 허구적 서사의 (재)독해와 '대안 정치'의 가능성, 생활 글쓰기(일기)에 기록된 개별 여행자의 도시 모빌리티 경험 등에 대해 논의한다. <모빌리티와 인문학>의 의의는 크게 두 가지다. 첫째, 그 동안 텍스트 연구에서 충분히 다루어지 않았던 자동차 모빌리티에 주목하게 해준다는 점이다. 둘째, 새 모빌리티 패러다임의 관점에서 텍스트의 미학에 관한 새로운 논의를 가능하게 해준다는 점이다.

Objective : Purpose of this study is to discuss benefits and implications of the clinical reasoning process and re-evaluation in the OTIPM by introducing a single case that occupational therapy intervention is provided based on the OTIPM. Methods : The case subject is a boy aged 5 years and 10 month who had diagnosed as attachment disorder and anxiety disorder from a pediatric psychiatrist before. The boy is referred to sensory integration therapy clinic and underwent occupational therapy intervention service twice a week for four month. Therapeutic activities for the intervention were consisted of sensory integration activities for restorative model, care-giver education for educational model, and performance skill training for acquisitional model. Measurements used in the initial evaluation are JSI-R, DDST-2, Social Maturity Test, KPPS-R, and observation-based performance task analysis. For the performance task analysis, performance skill items were constructed based on the Occupational Therapy Process Framework (OTPF), and those were assessed by the evaluation system of Assessment of Motor and Process Skill (AMPS) and Evaluation of Social Participation (ESI). Results : The detail process of implementing of the OTIPM in this study is reported by following four phases; 1) establish client-centered performance context; 2) establish baseline and interpret cause (initial evaluation); 3) intervention planning and implementing; and 4) recognize intervention outcome (reevaluation). Conclusion : In this case, occupational therapist could provide the client an occupation-based intervention within comprehensive performance context based on the OTIPM. Therapist could clearly identify the cause of problematic performance skills and behaviors and so provide effective intervention to improve client's occupational performance. Additionally, it was found that client's satisfaction of the intervention can be raised when the concept of 'who is the client' is expanded based on the OTIPM. From this study, it is proposed that OTIPM may be a model educible 'comprehensive' enhancement of 'specific' occupational engagement, as it considers both improvement of occupational performance and satisfaction.

The purpose of this study is to measure the effect of musical activities on children's aggressiveness using percussion playing through case studies and to present the therapeutic programs. Musical activities using percussion playing were organized for three aggressive children. Twenty-one small group sessions were conducted over seven weeks with 30 minutes given each session. Fourth-grade children involved in using Aggressiveness Measuring Tool for Teachers-revised by Gwak Geum-Joo(1992) was selected for case studies. Children's impulsiveness was also tested through self-test measuring tool for impulsiveness-revision of 16 questions used by Cho Hae Yeon (2001) and Lee Joo Shik (2003). As quantitative method, comparative analysis was made between the pre and post test results using measuring tools for aggressiveness and impulsiveness of children as well as between aggressive behaviors occurring in the initial stage of the first three sessions and in the latter stage of the last three sessions. Qualitative method was used at the same time to examine the effect of percussion playing on children. After the musical activities, child A showed reduced Aggressive Measuring Tool scores from 19 to 18, with child B from 23 to 19 and child C from 21 to 18. The results show that occurrence of aggressive behaviors were lowered in the post test. Impulsiveness Measuring Tool scores in the post test were decreased as well in all three children. During the music therapy programs, it was also observed that the frequency of the target behaviors in all three children has reduced more in the latter stage than the initial stage of music therapy. The qualitative findings indicate that the children experienced releasing stress through self-expression after percussion playing. These findings indicate therapeutic effectiveness of music therapy using on percussion playing in reducing aggressiveness of children as well as the effectiveness of percussion as a therapeutic intervention for aggressive children. These results can be adapted and reapplied by teachers in primary schools to approach children with behavior problems, and can present a useful therapeutic approach to therapists practicing in clinical environments.

The purpose of this study is to explore the characteristics and meaning of the Korean American women's poetry in New York area. New York area poetry has been led by women poets from the very beginning of the paragraph. In this paper, set the starting point of "New York Literature" in 1991, and classified the poets who had started their activities in the past as a first generation, and poets who have been active since then, as second generation. The characteristics and meaning of women's poetry were examined by focusing on Kwak Sang-hee, Kim Jung-ki, Kim Song-hee, and Choi Jeong-ja in the first generation, Jo Seong-Ja, and Shin Ji-hye, An Young-ae, Bok Young-mi in the second generation. On the one hand, they share a common sentiment of immigrant women, while on the other they show a slightly different world recognition and identity for each poet. The characteristics of women's poetry in New York area are as follows: ① they express the nostalgia for their experience and home in a strange space, ② that they reveal their identity as a mother and a poet, ③ they show the experience of labor and other consciousness, and ④ shows the changing identity through Nomadistic thought and de-territorialization. Although the content of the prototypes of female poets differ slightly depending on the motive and timing of immigration, in the early days of immigration, mainly the nostalgia for their hometowns and the consciousness of the Gentiles have become a poetic theme, and the alienation ceremony, And as time passes it shows consciousness as a settler who regards America as their second hometown. In the 1990s, most of the first-generation women poets have been harsh with the process of adaptation and settlement, revealing the nostalgia for their hometowns. Jo Seong-Ja and Shin Ji-hye, who are doing their work in the 1990s as a settlement stage, are adapting easily to American society compared to their predecessors. They also show that they are able to overcome ethnicity and race, It shows the open vision and identity to overcome. If the first generation of immigrant women has been leading the flow of New York poetry since the liberation, it is meaningful that second generation of women's poetry can be used as a measure of future change and development of New York poetry.

Purpose: This study was a part of a drive to develop a community health center-based hospice management model which is concerned with hospice care at a community health care setting and available resources of the local community. Methods: Development of a community health center-based hospice management model involved evaluation of existing hospice-related research, including literature review, and research on hospice facilities at the study site, as well as evaluation of model operation. The latter involved community health center-based hospice test operation, and evaluation of test operation by a research team, including of a nursing professor majoring in hospice care and staffs from a community health center in Busan metropolitan city, regional cancer center, and regional terminal cancer patient medical institute. The study was conducted in the 2008 calendar year. Results: The community health center-based hospice management model provides service linked with local community resources, focusing on the local community health center. Financial and administrative assistance is provided by the regional cancer center, with collaboration from academic health care professionals who guide the operation management. The community health center hospice nurse in consultation with a visiting nurse team registers terminally-ill cancer patients and, after assessment, the hospice team prioritize hospice care during team meeting. Care is delivered by staffs and volunteers. Conclusion: The developed community health center-based hospice operation management model maximally utilizes available community health resources to produce qualitative improvement of regional health and welfare policy through improving the lives of home-based cancer patients and their family who are in medical blind spot.

Purpose: One of the critical aspects on dispensing glasses is to match the center of pupils to the optical center of lenses as the mismatched glasses are able to induce uncomfortable effects called prism which has been known to induce phoria, a main cause for asthenopia in many cases. Therefore, we investigated the induced prism occurred by mismatching centers between the center of pupils and the optical center of lenses. Methods: In this study, total 103 subjects were examined whether the center of pupils and the optical center of lenses are matched in horizontal and vertical directions, and then, the data was categorized into 4 groups based on the structural components of glasses. Total amount of prism was compared to show the effect of the glasses frame on the prism induction, and the value of measured prism was compared with the German RAL-RG 915 regulations. Results: The results in respect to the horizontal component showed that the induced prism was not found in 10.7% of total subjects. 73.8% of total subjects were influenced by induced prism, the range of prism was in a tolerance level. However, the 15.5% of total subjects seemed to be influenced by prism which is out of the criterion of tolerance. In case of vertical component, 23.3% of total subjects showed no effects of prism while early adopting glasses, 54.4% of total subjects showed a little prism effect within the criterion of tolerance, and 22.3% of total subjects showed the prism effect out of the tolerance range. This data indicates that group A and B that are less likely adjustable by fitting induce more prism than group C and D in horizontal and vertical components. Conclusions: In higher refractive error condition, it was found that aligning the optical center of lenses with the center of pupils by pre-fitting of glasses frame minimized prism induction in horizontal and vertical components, which ameliorates ocular fatigue. Therefore, appropriate optometric dispensing through fitting by opticians and precise design about monocular PD and monocular Oh are necessary to improve visual perception.

시뮬레이션 기법을 이용한 시스템의 분석에 있어서 실험의 자동화는 현재 많은 연구와 개발이 진행 중인 분야이다. 컴퓨터와 정보통신 시스템에 대한 시뮬레이션의 예를 들어 보면, 수많은 모델을 대한 시뮬레이션을 수행할 경우 자동화된 실험의 제어가 요구되고 있다. 시뮬레이션 수행회수, 수행길이, 데이터 수집방법 등과 관련하여 시뮬레이션 실험방법이 자동화가 되지 않으면, 시뮬레이션 실험에 필요한 시간과 인적 자원이 상당히 커지게 되며 출력데이터에 대한 분석에 있어서도 어려움이 따르게 된다. 시뮬레이션 실험방법을 자동화하면서 효율적인 시뮬레이션 출력분석을 위해서는 시뮬레이션을 수행하는 경우에 항상 발생하는 초기편의 (initial bias)를 제거하는 문제가 선결되어야 한다. 시뮬레이션 출력분석에 사용되는 데이터들이 초기편의를 반영하지 않는 안정상태에서 수집된 것이어야만 실제 시스템에 대한 올바른 해석이 가능하다. 실제로 시뮬레이션 출력분석과 관련하여 가장 중요하면서도 어려운 문제는 시뮬레이션의 출력데이터가 이루는 추계적 과정 (stochastic process)의 안정상태 평균과 이 평균에 대한 신뢰구간(confidence interval: c. i.)을 구하는 것이다. 한 신뢰구간에 포함되어 있는 정보는 의사결정자에게 얼마나 정확하게 평균을 추정할 구 있는지 알려 준다. 그러나, 신뢰구간을 구성하는 일은 하나의 시뮬레이션으로부터 얻어진 출력데이터가 일반적으로 비정체상태(nonstationary)이고 자동상관(autocorrelated)되어 있기 때문에, 전통적인 통계적인 기법을 직접적으로 이용할 수 없다. 이러한 문제를 해결하기 위해 시뮬레이션 출력데이터 분석기법이 사용된다.본 논문에서는 초기편의를 제거하기 위해서 필요한 출력데이터의 제거시점을 찾는 새로운 기법으로, 유클리드 거리(Euclidean distance: ED)를 이용한 방법과 현재 패턴 분류(pattern classification) 문제에 널리 사용 중인 역전파 신경망(backpropagation neural networks: BNN) 알고리듬을 이용하는 방법을 제시한다. 이 기법들은 대다수의 기존의 기법과는 달리 시험수행(pilot run)이 필요 없으며, 시뮬레이션의 단일수행(single run) 중에 제거시점을 결정할 수 있다. 제거시점과 관련된 기존 연구는 다음과 같다. 콘웨이방법은 현재의 데이터가 이후 데이터의 최대값이나 최소값이 아니면 이 데이터를 제거시점으로 결정하는데, 알고기듬 구조상 온라인으로 제거시점 결정이 불가능하다. 콘웨이방법이 알고리듬의 성격상 온라인이 불가능한 반면, 수정콘웨이방법 (Modified Conway Rule: MCR)은 현재의 데이터가 이전 데이터와 비교했을 때 최대값이나 최소값이 아닌 경우 현재의 데이터를 제거시점으로 결정하기 때문에 온라인이 가능하다. 평균교차방법(Crossings-of-the-Mean Rule: CMR)은 누적평균을 이용하면서 이 평균을 중심으로 관측치가 위에서 아래로, 또는 아래서 위로 교차하는 회수로 결정한다. 이 기법을 사용하려면 교차회수를 결정해야 하는데, 일반적으로 결정된 교차회수가 시스템에 상관없이 일반적으로 적용가능하지 않다는 문제점이 있다. 누적평균방법(Cumulative-Mean Rule: CMR2)은 여러 번의 시험수행을 통해서 얻어진 출력데이터에 대한 총누적평균(grand cumulative mean)을 그래프로 그린 다음, 안정상태인 점을 육안으로 결정한다. 이 방법은 여러 번의 시뮬레이션을 수행에서 얻어진 데이터들의 평균들에 대한 누적평균을 사용하기 매문에 온라인 제거시점 결정이 불가능하며, 작업자가 그래프를 보고 임의로 결정해야 하는 단점이 있다. Welch방법(Welch's Method: WM)은 브라운 브리지(Brownian bridge) 통계량()을 사용하는데, n이 무한에 가까워질 때, 이 브라운 브리지 분포(Brownian bridge distribution)에 수렴하는 성질을 이용한다. 시뮬레이션 출력데이터를 가지고 배치를 구성한 후 하나의 배치를 표본으로 사용한다. 이 기법은 알고리듬이 복잡하고, 값을 추정해야 하는 단점이 있다. Law-Kelton방법(Law-Kelton's Method: LKM)은 회귀 (regression)이론에 기초하는데, 시뮬레이션이 종료된 후 누적평균데이터에 대해서 회귀직선을 적합(fitting)시킨다. 회귀직선의 기울기가 0이라는 귀무가설이 채택되면 그 시점을 제거시점으로 결정한다. 일단 시뮬레이션이 종료된 다음, 데이터가 모아진 순서의 반대 순서로 데이터를 이용하기 때문에 온라인이 불가능하다. Welch절차(Welch's Procedure: WP)는 5회이상의 시뮬레이션수행을 통해 수집한 데이터의 이동평균을 이용해서 시각적으로 제거시점을 결정해야 하며, 반복제거방법을 사용해야 하기 때문에 온라인 제거시점의 결정이 불가능하다. 또한, 한번에 이동할 데이터의 크기(window size)를 결정해야 한다. 지금까지 알아 본 것처럼, 기존의 방법들은 시뮬레이션의 단일 수행 중의 온라인 제거시점 결정의 관점에서는 미약한 면이 있다. 또한, 현재의 시뮬레이션 상용소프트웨어는 작업자로 하여금 제거시점을 임의로 결정하도록 하기 때문에, 실험중인 시스템에 대해서 정확하고도 정량적으로 제거시점을 결정할 수 없게 되어 있다. 사용자가 임의로 제거시점을 결정하게 되면, 초기편의 문제를 효과적으로 해결하기 어려울 뿐만 아니라, 필요 이상으로 너무 많은 양을 제거하거나 초기편의를 해결하지 못할 만큼 너무 적은 양을 제거할 가능성이 커지게 된다. 또한, 기존의 방법들의 대부분은 제거시점을 찾기 위해서 시험수행이 필요하다. 즉, 안정상태 시점만을 찾기 위한 시뮬레이션 수행이 필요하며, 이렇게 사용된 시뮬레이션은 출력분석에 사용되지 않기 때문에 시간적인 손실이 크게 된다.
