This study is for finding out Career-barrier of the disabled, and for analyzing the effect of Career-barrier on the dysfunctional career-thought. For this study, 180 disabled people were surveyed. The results are as follows; First, the career-barriers that the disabled people perceive are in order; lack of occupational information, lack of social support, low self-concept clarity, low self-efficiency, and conflict with significant-others. Secondly, difference of career-barrier, caused by the traits of the disabled, has influenced the lack of self clarity and occupational information. In addition, among the types of the disabilities, it is proven that the psychological disability highly correlated to the social support, unlikely to gender difference and job experience. Thirdly, the most influential reason on the decision-making confusion for finding job among the sub-variables of dysfunctional career-thought were; low self-concept clarity, conflict with significant-others, and low self-efficiency. While it turned out that the most influential career-barrier on the performance anxiety for disabled people were low self-efficiency and conflict with significant-others.

The fourth industrial revolution became a decisive opportunity to increase our dependence on non-face-to-face services. Therefore, this study tried to derive a new strategic plan for non-face-to-face marketing by discussing the short-form branded content currently in the spotlight among the digital native generation. In particular, focusing on the phenomenon of co-viewing, where short-form branded content is viewed and communicated on social media, how exposure type of branded content affect attitudes toward short-form branded content and the products it contains verified. In addition, this research presents the perceived sense of belonging as a mediating variable. It was confirmed through an experiment whether the sense of belonging perceived by consumers during the co-viewing process significantly mediated the relationship between the exposure types and consumer attitudes. As a result of the study, it was found that the exposure type significantly affected the attitude towards the contents and the products contained in them. Furthermore, the perceived sense of belonging was also significant as a mediating variable.

식생지수 시계열 자료를 이용한 식생 및 토지피복 모니터링을 수행하기 위해서는 구름으로 인한 누락 및 왜곡된 식생지수 문제를 먼저 해결해야만 한다. 특히 한반도와 같이 여름철 집중 호우기에 대부분의 영상에 구름이 존재하는 경우 이들 구름화소를 제거하거나 복원하지 않을 경우, 분석 결과에 상당한 왜곡이 발생하거나 특정 시기의 영상자료를 분석에 반영할 수 없는 경우가 발생하게 된다. HANTS 알고리즘은 이 같은 구름 화소 문제를 해결하기 위한 알고리즘으로 연중 식생지수의 변화는 비교적 단순한 반복적 주기함수의 형태를 가지므로 소수의 cos 함수를 이용한 푸리에 근사식으로 전체 연중 식생지수를 표현할 수 있다는 가정에서 출발한다. 이 때 구름화소로 인한 원식생지수와의 차이가 특정 임계값을 초과하였을 경우 해당 관측치를 근사과정에서 제외함으로써 구름의 영향을 받지 않은 식생지수 시계열 자료만을 이용하게 된다. 이 과정을 수행하기 위해서는 몇몇 제어변수의 설정이 필요한데, 본 연구에서는 한반도와 같이 특정 시기에 장기간 구름이 분포하는 상황에서 최적의 식생지수 복원을 위한 HANTS 알고리즘의 제어변수를 선정하고 재구축된 식생지수를 평가하였다. 이를 위한 실험으로 2002년 대전 지역의 MODIS Terra 식생지수 시계열 영상을 대상으로 HANTS 알고리즘을 주요 식생피복별로 적용해 보았다.

Changes of protein synthesis in the isolated egg chambers were studied during oogenesis of Drosophila melanogaster. Protein synthesis did not change much in quantity except that the activity was slightly enhanced at the stages 11 and 12, when new structures such as vitelline membranes and yolk granules were made, but considerably changed in quality during oogenesis. Protein synthesis was believed to occur mainly in the follicle cells, and a number of stage-specific proteins were found to differ at various stages. The observations suggest that proteins synthesized in the cells within chambers as well as those from the outside of the chambers might be directly required for the growth and maturation of oocytes in Drosophila.

A whole society has become software-driven and each independent fields has become convergence based on computing as the new digital economy era has come. This change affect computational literacy using computational thinking is emphasized the importance as the core competence for the future living. It means that supply of manpower with understanding software principle will decide the fate of the country. For this reason, each country are reinforcing computer science education or computing education. In this paper, we researched and analysed on new global trends of computer education in school especially focused on national curriculum and policy.

지금까지 수공구조물의 설계와 기존 시설의 안전도를 평가시 수문, 수리 및 경제학적 함수들에서 발생하는 불확실성을 설명하기 위하여 안전율 또는 여유고를 증가시키거나 이들 정보의 양과 질을 증가시켜 데이터베이스를 확장하고 측정오차를 최소화시키며, 전통적인 통계해석을 적용하였다. 공공의 안전을 확보하기 위하여 설계과정에 안전율 또는 여유고가 도입되었으나 이것은 단순히 보다 높은 재현기간의 적용을 의미하며, 수문현상이 가지는 추계학적 특성보다 확정론적인 근거로부터 안전설계 개념이 개발되었다. 수자원 계획시 고려되는 부하와 저항은 확정론적인 고정치가 아니라 시간에 따라 변하고 동적이며, 무작위적이므로 확률 변수로서 고려되어야 한다. 이에 따라 최근 수자원 계획과정에서 불확실성 해석에 의한 위험도 분석 개념이 도입되고 있으며, 특히 이상기후 및 집중호우의 빈발, 급격한 도시화로 인한 유출양상의 변화 등으로 급증하고 있는 훙수피해를 감안할 때 설계빈도의 상향조정과 같은 확정론적인 방법보다는 매개변수 또는 함수의 불확실성을 고려한 위험도 해석의 필요성이 더욱 증대되고 있는 실정이다. 따라서 본 논문에서는 수자원 계획시 입력자료 및 매개변수의 불확실성과 불확실성의 분리를 고려한 홍수량의 산정 및 각 매개변수의 영향을 평가하여 홍수위험도 해석에 있어서 모델 매개변수의 영향 규명과 처리방안을 제시하고자 한다.

In this paper, we propose an efficient space-time block coding (STBC) scheme in a cooperative satellite-terrestrial system. The proposed STBC scheme has code rate 1 for a 3 transmit antenna scheme. Because the channel matrix of the proposed scheme is orthogonal, we can use a simple linear decoding algorithm and also can expect improved performance over the conventional scheme. The simulation results demonstrate that the proposed scheme has improved performance for bit error rates (BER) than several conventional STBC schemes. In addition, we investigate performance simulation results by power imbalance between the terrestrial repeaters and satellite.

Most previous research on safer sex and condom use has been mainly focused on individual's dispositional factors such as attitudes, perceived control, intention, and etc. However, a few researchers recently started to propose that condom use is not a matter of individual behavioral decision but a product of serious interactive negotiation processes and condom negotiation would be the proximal key-determinant of condom use behaviors. The present research categorized condom-negotiation strategies and preferences of Korean college students and examined relationship between the strategies and other sex-related concepts. 186 participants' strategies on a free-response questions of condom negotiation revealed 7 types of persuasion strategies for condom use; Pregnancy risk, responsibility, care for partner, withholding sex, sexual disease, direct request, and sexual satisfaction (in order of preference). 6 types of persuasion strategies for condom avoid were abstracted: Pregnancy free, Sexual satisfaction, responsibility, direct request, unfaith toward condom, and withholding sex (in order of preference). The effects of gender, sexual experience, and culture were found and discussed in their implications for sexual education,
