This study intended to analyze what factors affect fundraising effectiveness in nonprofit social service organizations. Focusing on organizational characteristics only, current studies did not address the importance of organizational capacity leading to organizational effectiveness. Based on the assumption of the relation between organizational capacity and effectiveness of nonprofit organizations, this study added factors indicating organizational capacity to the current model. After collecting data from 147 staffs involving in fundraising activities of nonprofit social service organizations, this study used a hierarchical regression analysis. The results showed that organizational capacity had a significant impact on the variance of fundraising effectiveness. Despite the limitations of the purposive sampling method, this study has implications to provide practical guideline for nonprofit managers and to develop a theoretical framework with a new perspective on organizational capacity.

The purpose of this study was to change of Psychological skills strategy and Self-management behavior according to the level of Resourcefulness of collegiate fencing-athletes. Methods: This study was a single case for 12-week intervention. and it took about 60-90 minutes, once a week. Participants were 154 Student athletes and 20 fencing-athletes. The effect of this study was utilized a questionnaire. To analyze the responses of research, the paired t-test were used for finding the significances of mean differences(p<.05). After 12 week education session the results are as follows: Firstly, high group of Resourcefulness showed greater increase in Attention and Image. low group of Resourcefulness showed greater increase in Will power, Goal Setting, Confidence, Attention, Image. Secondly, high group of Resourcefulness showed greater increase in Physical management. low group of Resourcefulness showed greater increase in Training management. fencing-athletes were significantly increased of capacity for Performance and self-management according to the level of Resourcefulness, after 12-weeks. This study suggested useful information about sport psychological skills training and intervention of fencing-athletes.

가상현실 시뮬레이터는 교육과 지식의 전달을 위한 도구로 발전하고 있으며, 과학교육 및 문화체험을 위한 첨단과학전시시스템의 수요가 증가하고 있다. 동역학적 계산을 기반으로 하는 기존의 가상현실 시뮬레이터는 컨텐츠의 변경이 어려운 단점이 있으며, 효과적인 지식전달 및 흥미 유발을 위해서는 운동감뿐만 아니라 다감각을 동원한 체감 시스템이 필요하다. 본 연구에서는 체감형 전시 시스템에 적합한 운동감 생성 방법과, 다감각 동원 가상현실효과 시스템을 설계하고 통합하였다. 제안된 방법은 영상의 시점변화를 기반으로 한 운동감 생성과, 미리 저장된 모션 라이브러리를 이용한 운동감 효과를 동시에 적용할 수 있으며, 관객의 상호작용에 의한 운동감 효과를 쉽게 추가할 수 있다. 관객의 다양한 감각을 이용한 가상현실 효과를 위하여 체감형 전시 시스템에 적합한 다양한 다감각 효과의 적용 방안을 모색하고, 효율적인 다감각 효과를 선정하여 실제 시스템에 적용하였다. 이를 통하여 체감형 전시를 위한 가상현실 효과 시스템의 기본 구조를 정립하였다.

The effects of adenosine and $N^6-cyclopentyladenosine$ (CPA) on superoxide production, myeloperoxidase release and $Ca^{2+}$ mobilization stimulated by fMLP in neutrophils were investigated. The effects were also observed on the stimulatory actions of C5a and PMA and the responses in lipopolysaccharide-primed neutrophils. In addition, the involvement of cAMP in the inhibitory action of adenosine was examined. The fMLP-stimulated neutrophil respiratory burst, degranulation and intracellular $Ca^{2+}$ mobilization may be regulated by activation of adenosine receptors. Adenosine may not affect the stimulated neutrophil responses due to activation of protein kinase C. fMLP-stimulated respiratory burst in lipopolysaccharide-primed neutrophils may be less sensitive to adenosine, compared with nonprimed cells. The inhibitory effect of theophylline in the presence of adenosine on neutrophil responses appears to be ascribed to accumulation of intracellular cAMP.

Ship noise is one of the important factors for the living and health of seafarers, and ef orts to reduce ship noise are actively underway. There are two methods of noise reduction: passive noise Control (PNC) and active noise control (ANC). Unlike cars and airplanes, ANC is not widely used for noise reduction on ships. This study aimed to reduce the noise generated in the engine room by using soundproof panels and high-frequency vibration generators, as well as active noise control (ANC). For this purpose, an experimental model was made using an acrylic box, and the noise reduction effect was measured under four conditions. The experimental results are as follows: First, the soundproof panel had a noise reduction effect in all ranges from 55 dB to 85 dB. In the case of using a high-frequency vibration generator, there was no ef ect in the low noise range such as 55 dB(A), but there was a noise reduction effect in the high noise range such as 70.8 dB(A) and 85 dB(A).Second, when the soundproof panel and the high-frequency vibration generator were used simultaneously, the noise reduction ef ect was up to -2.2 dB(A). The results of this experiment were obtained from an experimental model made of acrylic, and they may be different from actual ships made of steel plate. In future studies, we plan to experiment using iron plate (considering the material, thickness, and structure) used in actual ships. We hope that this study will help to improve the living environment and health of seafarers on ships.
