Objectives : DAMA cases were analyzed to examine what the main casual factors of DAMA were and how to deal with these cases effectively in hospital with the DAMA interdisciplinary team including medical social worker whose role is to perform psycho-social assessment, family counsel, to evaluate family's DAMA need. Patients and Methods : The content analysis of medical record and social work record were reviewed in 37 cases referred by medical doctor to DAMA team. These cases were reported by patients' self discharge request or family's request for discharge from September 1998 to February 2000. The DAMA team consists of Assistant Director of Hospital as team leader, medical staff in-charge, social worker, QI nurse, other staff members who are not involved in direct treatment for patient, and administrative clerk. Results : The results of content analysis are as follows : 1) The most causal factors of DAMA consist of combination of more than 2 factors. 2) The major decision-maker is revealed to be son and daughter of patient. 3) In 59.4% of cases, family was not informed of patients' prognosis, alternatives, the consequence of DAMA at all. 4) In cases of DAMA report, the rapid intervention of social worker is carried out. Conclusion : In this study, we propose the interdisciplinary team approach to make decision legitimately and ethically for DAMA. The suggestions from this study are as follows : 1) To deal with DAMA case properly, the interdisciplinary team approach should be considered. 2) The criteria for DAMA case should be formed carefully. For the explicit selection of DAMA case, preliminary system for high-risk patient screening is recommended. 3) The medical social worker is available for the psycho-social problems of the patient once family members. For the effective family counselling, discharge planning and nursing home placement, the participation of medical social worker should be mandatory.

Objective: It is to extract training items that have a high relationship with the improvement of weightlifting records through correlation and regression analysis between training methods used commonly in the field and Snatch records and jerk records. Through this, it is intended to promote training efficiency to improve the records of weightlifters. Method: For 90 elite weightlifters of the professional teams, 4 groups (lightweight (30 people): 61 kg, 67 kg, 73 kg., middleweight (30 people): 81 kg, 89 kg, 96 kg., heavyweight (30 people): 102 kg, 109 kg, +109 kg., the whole group (90 people)) were divided. At the significance level of 0.05, correlation analysis and linear regression analysis were performed between record of training methods used widely in the field and Snatch records and Jerk records. Results: First, the better the record in Jerk, the better the Snatch record. Second, the three training methods HS, ForceS and WP performed in the field were all found to be important factors related to the improvement of Snatch record. Third, In the jerk where there are more types of training than Snatch, three training methods (HC, ForceS, BPP) appeared to be an important training method for improving the jerk record. Conclusion: While many training methods have been devised and carried out in the field, 3 types of training (HS, ForceS, WP) for improving Snatch record and 3 types of training (HC, ForceS, BPP) for improving Jerk record was found to be the most influential training method. Since all of them showed a large value of explanatory power by regression analysis, it is considered that this study is meaningful in that it can promote training efficiency by simplifying although there are many types of training for athletes.

This study is to analyze the kinematic variables in release motion of discuss throwing. For the matter, 5 people from the national team and collegiate discuss throwing in the year 2001 were chosen as the subjects and two S-VHS video cameras set in 60frames/sec were used for recording their motions. Coordinated raw positions data through digitizing are smoothing by butter-worth 's low-pass filtering method at a cut off frequency 6.0Hz. and the direct linear transformation(DLT) method was employed to obtain 3-D position coordinates. The conclusions were as follows; 1. The better record players showed the shorter approach time in the last support phase. 2. In the displacement CG, the better record players showed the shorter displacement in medial-lateral direction, and the longer displacement in horizontal direction. In the motion, the COG showed longer displacement vertical direction. 3. The better record players showed the faster horizontal velocity than vertical velocity in the release. 4. The better record players showed to take the posture of vertical axis in the release.

본 연구의 목적은 LP 산업의 구조를 분석하여 해당 산업의 매력도를 이해하고 시사점을 도출하는 것에 있다. 선행연구는 급증한 LP 수요에 주목하며 소비자 관점에서 해당 소비와 LP 산업을 이해하였으나, 본 연구는 LP의 생산 및 유통의 주체에 초점을 맞추어 진행하였다. 본 논문은 LP 산업 내 현업종사자들과 심층면접 및 다양한 이차자료를 통해 자료를 수집하고, 이를 포터(1980/2008)의 5요인 이론(Five Forces model)으로 분석하였다. 분석결과, LP 산업의 매력도는 산업 내 경쟁 강도가 적정하고 구매자의 교섭력이 약하다는 측면에서는 긍정적이지만, 신규 진입자와 대체재의 위협 및 공급자의 교섭력이 강하다는 측면에서 부정적이다. 이는 LP 산업에 신규 진입하려는 기업들의 전략적 판단을 위한 기초자료로서의 의의가 있다.

In this study, we aimed to observe the diversity of aquatic fungi by collecting deposits of soil, plants, and plant litter from streams and rivers. Three Penicillium strains were isolated from soil in streams. Based on the morphological characteristics and phylogenetic analysis using DNA sequences of the internal transcribed spacer, β-tubulin and calmodulin genes, the isolates were identified as Penicillium guanacastense, P. saturniforme, and P. scabrosum. These three fungi have not yet been reported in Korea.

Objective: The aim of this study was to analyze the effects of bobsleigh shoes on the lower extremity range of motion and start speed lap time and to develop bobsleigh shoes suitable for winter environments and Korean players based on sports science and optimized biomechanical performance. Background: The bobsleigh shoes used in the start section of the sport are one of the most important equipment for improving athletes' performances. Despite the importance of the start section, there are no shoes that are specifically designed for Korean bobsleigh athletes. Thus, Korean athletes have to wear sprint spike shoes instead of bobsleigh shoes to practice the start. Method: The subjects included four bobsleigh athletes from the Gangwon Province Bobsleigh Skeleton Federation. The study selected the bobsleigh shoe type A (company A) and type B (company B). We analyzed the lower extremity range of motion and sprint time (start line to 10 m) using a Motion Analysis System (USA). Results: In the measurement of the time required for the bobsleigh start section (10 m), the type A shoes demonstrated the fastest section record by $2.765{\pm}0.086sec$ and yielded more efficient movements, hip and knee flexion, hip extension, ankle dorsiflexion, plantar flexion, and inversion than the type B shoes. Conclusion: Type A shoes can yield a better performance via effective lower extremity movements in the bobsleigh start section. Application: In the future, functional analysis should be conducted by comparing the upper material properties, comfort, and muscle fatigue of bobsleigh shoes based on the Type A shoes to develop such shoes suitable for Koreans.

범주형 시계열 자료의 군집화에 대하여 정리해 보았다. 시계열 자료의 군집화는 일반적인 군집화에 시간을 고려해야하는 측면이 있다. 한편, 범주형 시계열 자료의 군집화에 대한 연구가 진행되었으나 현재 정리 요약된 국내외 논문을 찾기 어렵다. 본 논문에서는 범주형 시계열을 군집화 하는 몇 가지 방법들을 제시하고 그 방법들을 비교하기 위해 프로야구 데이터를 이용하였다. 프로야구 팀들 간에 어떤 팀이 특정 팀에 유독 약한 경기력을 보이는 경우가 있다. 국내 최강이라는 S팀이 유독 H팀에게 그런 경우가 그렇다. 2015년 S팀의 상대전적의 군집화를 통해 S팀과 H팀의 관계가 유별난 지를 밝히려 한다. 통계적으로 말하자면, 승/패로 이루어진 시계열 자료의 군집화를 수행하려는 것이다. 분석결과 S팀과 H팀과의 관계가 다른 팀들과의 관계에 비해 눈에 띠는 차이가 있음을 알 수 있었다.
