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.

The purpose of this study was to examine the multicultural sensitivity of early childhood teachers, their perception on the purpose of multicultural education and any possible differences in those regards according to their background variables in an effort to determine the influence of the multicultural sensitivity of early childhood teachers and their perception on the purpose of multiculitural education on multicultural sensitivity, as the two variables were closely bound up with multicultural teaching efficacy. The subjects in this study were 283 selected early childhood teachers. The findings of the study were as follows: First, as for perception on the purpose of multicultural education, caring-centered perception was most common among the early childhood teachers, and their scores in multicultural sensitivity were a little above average. Second, there were significant differences among the teachers in multicultural sensitivity and perception on the purpose of multicultural education according to career, age and academic credential. Third, multicultural sensitivity and four perceptions on the purpose of multicultural education had a significant positive correlation with multicultural teaching efficacy. Multicultural sensitivity exerted the largest influence on multicultural teaching efficacy. Among the four perceptions of the purpose of multicultural education, caring-centered perception and social action-centered one turned out to have an impact on the subvariables of multicultural teaching efficacy. This study will provide basic information to prepare some solutions that enforce ealry childhood teachers' mulitucultutral education ability by improving their multicultural teaching efficacy.

This study evaluates the impact of an information security policy sanction, a perceived threat, and the perception of the information security climate on a compliance behavioral intention. The research method was structured with a cross-sectional study design for the prospect and goal orientation. The variables used in the analysis are information security policy sanction, perceived threat, perception of information security climate, and compliance behavioral intention. Progress in this research consists of measuring the prospect and goal orientation, and then measuring the four variables. As a result, the prospect had a significant effect on the perception of the information security climate, and it was found that the influence of the gain-based condition was greater than the loss-based condition. Goal orientation had a significant effect on the information security policy sanction, the perceived threat, and the compliance behavioral intention, and the influence of the development-based condition was greater than the stability-based condition. Both prospect and goal orientation had an interactive effect on the compliance behavioral intention. The exploration model was verified as a mediation model. In addition, the discussion includes the appropriate implications for information security based on these research results.

The purpose of this study is to analyze the perception of Korean universities' education specialists and seek direction for the development of MOOCs. To investigate this, 64 Korean university education specialists were surveyed about the educational goals of MOOCs and their perception of micro and macro issues. As a result, Korean university education specialists recognized MOOCs' educational goals as an innovation of education methods. Also, negative acknowledgment that issuance of certificates would cause confusion in the degree system, which is interpreted as a tendency to recognize MOOCs as a complementary material. On a macroscopic level, overall outlook was negative for K-MOOC. However, since K-MOOC is highly perceived to be subversive, it is necessary to discuss the possibility of using MOOCs. Accordingly, it suggested the institutional improvement for the utilization of K-MOOC and the possibility of joint development between universities.

Standards offer numerous opportunities and benefits not only to provide effective and efficient way for business goals internally, but also to increase company's competitiveness externally. However SMBs can't get have benefits from standards management due to lack of resources and awareness. The purpose of this study is to investigate the role of standard management in business hierarchy from SMBs' cases leading to raising the awareness and providing strategic implications for standards management. The utilization of Standards management was investigated by adopting Anthony framework and Miles and Snow typology targeting SMBs which have awarded the World Standards Day Prize. The results of case study indicated that standards can be used as not only a strategic tool for achieving business goal and but also an effective way for raising brand awareness in global market. This study has originality and practical value in that it enhances the awareness and provides strategic implications for standards management in global business environment.

제스처 인식은 직관적일 뿐 아니라, 몇 가지의 기본 구성요소에 의하여 코드화(code)가 용이하여, 인간과 컴퓨터의 상호작용(HCI, Human-Computer Interaction)에 있어서 폭넓게 사용되고 있다. 본 논문에서는 손의 모양이나 크기와 같은 개인차 및 조명의 변화나 배율과 같은 입력환경의 영향을 최소화하여, 특별한 초기화 과정이나 모델의 준비과정 없이도 제스처를 인식할 수 있고, 적은 계산량으로 실시간 인식이 가능한 제스처 인식 시스템의 개발을 목표로 한다. 본 논문에서는 손에 부착하는 센서나 마커 없이, CCD 카메라에 의하여 입력된 컬러영상에서, 컬러정보 및 동작정보를 이용하여 손영역을 추출하고, 추출된 손의 경계선 정보를 이용하여 경계선-중심 거리 함수를 생성했다. 그리고, 손가락의 끝 부분에서는 경계선-중심 거리가 극대점을 이룬다는 원리를 이용하여 생성된 함수의 주파수를 분석하여 극대점을 구함으로써 각각의 손가락 끝 위치를 찾고, 손의 자세를 인식하여 제스처를 인식했다. 또한 본 논문에서 제안된 제스처 인식 방법은 PC상에서 구현되어 그 유용성과 실효성이 증명되었다.

본 논문은 FM 라디오 방송중의 오디오 신호를 블록단위로 음악 및 음성을 검출하는 알고리즘에 대한 것으로, 이를 기반으로 방송중의 노래(가요, 팝, 클래식‥‥)만을 자동으로 인식하여 녹음하는 알고리즘을 개발한다. 본 논문에서는 기존에 제안되었던 것[1-4]과 같이 단지 음악과 음성을 구분함과 동시에 음악구간의 논리적 조합으로 이루어진 노래를 자동으로 인식하여 녹음하는 것을 알고리즘의 최종 목표로 한다. 알고리즘의 접근 역시 기존의 음소단위의 모델링을 거치는 GMM 기반의 접근이 아니기 때문에 모델링에 대한 훈련과정이 필요 없고, 시간영역에서의 오디오신호가 가지고 있는 직관적인 특징을 분석함으로써 비교적 적은 연산으로 실시간 구현이 가능하다.
