This empirical study focused on examining the relationship between transactional transformational leadership style and power of construction project manager and the organizational effectiveness, respectively, and the moderating role of power between leadership and the organizational effectiveness. A 790 numbers useful questionnaires were obtained from the stuffs working at the construction sites excluding project managers. Internal consistency test using Cronbach's ${\alpha}$ and confirmatory factor analysis were conducted for the reliability and validity of the scales respectively. And cluster analysis and multivariate analysis of variance (MANOVA) were conducted to test the hypotheses. The results and implications are as follows. First, the leadership styles of project managers influence positively the subordinates' job satisfaction but not organizational commitment in construction project. Second, the power styles of project managers influence positively the subordinates' job satisfaction and organizational commitment. Third, the leadership styles of the project managers influence positively the subordinates' job satisfaction and organizational commitment by the power moderating role. The implication of this result is important because of the fact that the transformational leadership can be useful even in the construction projects. And the moderating role of the project manage's power suggests.

To study the influence of leadership types on achievement goal orientation of high school athletes, Multifactor Leadership Questionnaire (MLQ) and Task and Ego Orientation in Sport Questionnaire (TEOSQ) were used to two-hundred-ninety athletes in Physical Education High Schools. The data from the survey were analyzed by SPSS 19.0 and the results of the analysis were as in the following. First, there were meaningful differences in the leadership factors according to the demographic characteristics. Male athletes tended to be more conscious of the individualized consideration(transformation leadership), contingent reward, management by exception(transactional leadership) of the leadership factors. Second, there were differences in athletes' achievement goal orientation. Comparing to the female athletes, male athletes gave more importance on the task goal orientation. Third, there were differences in the leader's leadership types on the athlete's achievement goal orientation. The athletes with self goal orientation and the individualized consideration (transformational leadership) of leadership types showed statistically meaningful differences. The athletes with high self goal orientation had a negative relationship to the individualized consideration and a positive relationship to the intellectual stimulation. The athletes with task goal orientation showed differences in the transactional leadership as well as in the contingent reward.

지난 2004년도는 식품 안전에 대한 사회적 이슈가 어느 해보다 뜨거웠다. 조류독감과 광유병, 불량만두소 사건 등의 식품사건이 연일 언론을 달구었고, 또 정부의 부정불량식품의 대한 규제강화 발표 등으로 식품 안전에 대한 사회적 관심이 고조되었다. 또한 이러한 식품 안전에 대한 사회적 이슈는 식품에 대한 소비자의 불신으로 이어지면서 과거에는 단순히 여기었던 식품 클레임에 대해서도 매우 민감한 반응을 보이면서 식품업계의 클레임이 예년보다 급증하였다. 뿐만 아니라 소비자의 클레임 제기 유형도 회사에 직접 제기하는 경우도 있지만 특히 포탈사이트. 언론 고발, 대형 유통 채널, 소비자단체, 정부기관 등의 다양한 채널을 이용하는 경우도 증가하고 있는 실정이다. 특히 정부의 식품위생법개정(안)의 유해식품 신고에 대한 고액의 포상금 지급이 발표되면서 악의든 선의든 소비자의 클레임에 대한 무리한 피해보상 요구도 날로 증가하고 있고, 또 이를 이용하는 식파라치와 악성소비자도 나타나게 되었다. 따라서 이러한 식품 안전에 대한 문제는 앞으로도 지속될 것이고, 또 식품의 클레임에 대해서도 더욱 강성화될 것으로 예상된다. 그러므로 이러한 사회적 환경 속에서 클레임에 대한 올바른 소비자 대응을 위한 클레임 처리 방안을 모색하지 않을 수 없다. 이에 클레임(claim)이란 무엇이며, 또 그 유형들은 어떤 것이 있는지 그리고 클레임의 대응 방법 및 Q&A를 살펴보고자 한다.

디지털 기술과 통신 기술의 발전으로 멀티미디어 컨텐츠가 급격히 증가하고 있다. 이러한 멀티미디어 컨텐츠는 다양한 유무선 서비스 환경에서 실시간 서비스가 가능해야 한다. 그러기 위해서는 멀티미디어 컨텐츠 중 가장 큰 비중을 차지하는 영상 및 오디오 컨텐츠에 대한 압축 및 전송 기술이 요구된다. 현재 여러 분야에서 영상 및 오디오에 대한 압축 표준으로는 MPEG 이 자리잡았다. 그리고 MPEG에 대한 많은 개선 노력이 있었으며 특히 테스트 모델인 TM5를 비롯한 많은 연구에서 벡터 추출이나 양자화를 이용한 방법을 중심으로 비트율을 제어하기 위한 부호화기 모델이 제시되었다. 본 논문에서는 기존의 연구 접근 방식과는 다르게 프레임 유형간의 거리를 이용하여 영상의 특성에 따라 보다 적합한 프레임 구조를 찾아 제안하였다. 즉 영상의 복잡도와 변화도에 따라 영상의 종류를 구분하고 각 종류별 영상에 대한 표준 MPEG 인코딩 화질을 기준으로 삼은 후, GOP구조 내에서 프레임 유형간의 거리를 조정하여 화질을 손상하지 않고 가장 적은 비트율을 보상하는 프레임구조를 실험 및 분석을 통해 찾아 제안하였다.

금융가격별 지표의 변동성 증가에 대처하려는 보수적 투자가들이 이용할 수 있는 매력적 방안의 하나가 보험부 투자기법이다. 그러나 이 투자유형은 설계에 상당한 신축성을 보이며 이는 동시에 투자성과 구조의 신축성으로 반영된다. 주요한 설계차원의 하나가 위험투자의 손실발생시 보상차원이다. 여기에 일반적 보험개념을 적용할 때 투자가가 직면하는 선택문제의 하나는 부분보험계약형 투자설계시 공제부보험형 전략과 공동보험형 전략간의 선택이다. 일반적 보험 이론에서는 전자가 후자에 대해 우월한 유형이라는 것이 밝혀져 있다. 본 연구는 이를 보험부투자에 응용할 때도 양 전략간에 어떠한 우월관계가 존재하는 지 알아보려 시도했다. 이를 위해 효율성 평가기준의 하나인 간편한 확률적 지배기준을 적용하였으며 분석결과는 생산적이었다. 두 전략 각각의 기대수익률의 확률분포를 대상으로 기대수익률이 상대적으로 공제부보험형 전략에서 공동보험형 전략에서보다 상대적으로 높거나 최소한 같은 경우에 전자가 후자를 지배하며 그 반대조건인 경우에는 양 전략간에 우열관계가 나타나지 않는다는 결과를 얻었다.

The purpose of this study was to analyze characteristics of problem solving process with proportional or compensational reasoning of the elementary school students. For this study, 85th grade students were selected and tested with Science Reasoning Task, information processing ability test and proportional and compensational reasoning tasks. This study revealed that students in mid concrete stage could solve the proportionality task and easy compensation task. But, most of the students could not solve difficult compensation task. And as the students got higher score in information processing test, it took them less time to solve the problem. The types of strategy used in solving proportional and compensational problem were categorized as the factor of change, building-up and the cross-product. Most of the students failed in problem solving used incorrect schema knowledge, procedure knowledge and strategy knowledge. Many students tended to use proportionality strategy to solve the difficult compensation task. Result of this study suggested that various task included different structure and the same schema knowledge can be effective for the advancement of students' proportional and compensational reasoning ability.

As the foodservice industry is labor intensive, the efficient management of human resources is an essential element for improving operational efficiency. This study was designed to investigate the performance level of human resource management in self-operated school foodservices and to examine the relationship between human resource management, organizational commitment, and productivity. Whether these factors rated differently by employment and job types was also examined. Data were collected through questionnaires distributed to 60 dieticians and 240 cooks in Seongnam and Yongin. Frequency analysis, factor analysis, the t-test and multiple regression analysis were tested using Minitab. Human resource management practices rated highly in the dimension of employee training (3.51), followed by working environment (3.39), and turnover management (3.37). In contrast, reward management (1.73) and working condition (1.56) received the lowest score. Organizational commitment scored 3.65 points, and showed that dedication (3.82) was the highest score; however, self-esteem (3.50) was the lowest score. For human resource management, there were significant differences between employment types as full time workers (3.85) rated management more highly than part-time worker (3.43). Overall productivity was fairly high, especially in high school foodservices. Only the performance appraisal had an influence on organizational commitment (${\beta}$=0.292, P<0.05). Productivity was positively correlated with human resource management (r=0.432, P<0.001) and organizational commitment (r=0.36, P<0.01). In conclusion, school foodservices need to establish objective performance standards, and increase employee morale by enhancing reward systems and working conditions. In particular, irregular employees require training with job performance standards and given a proper reward program, depending on their performance, to improve organizational commitment.
