중대시민재해의 대상은 공중이용시설, 공중교통수단, 그리고 원료·제조물로 구성되고, 재해를 관리하기 위한 안전보건체계와 이에 대한 이행체계로 구성된다. 중대시민재해의 주요 대상 기관은 지자체와 공공기관, 그리고 다중밀집시설 사업장을 가진 업체가 주요 대상이 된다. 특히 지자체의 경우에 광범위한 시설물을 관리하기 때문에 그 관리체계의 복잡함이 발생하며 이에 따라, 이를 효과적으로 관리할 수 있는 시스템 관점의 체계를 본 연구에서 초점을 두었다.

Recently studies on application development and utilization using sensors and devices embedded in smartphones have flourished at home and abroad. This study aimed to analyze the accuracy of the images of smartphone to determine three-dimension position of close objects prior to the development of photogrammetric system applying smartphone and evaluate the feasibility to use. First of all, camera calibration was conducted on autofocus and infinite focus. Regarding camera calibration distortion model with balance system and unbalance system was used for the decision of lens distortion coefficient, the results of calibration on 16 types of projects showed that all cases were in RMS error by less than 1 mm from bundle adjustment. Also in terms of autofocus and infinite focus on S and S2 model, the pattern of distorted curve was almost the same, so it could be judged that change in distortion pattern according to focus mode is very little. The result comparison according to autofocus and infinite focus and the result comparison according to a software used for multi-image processing showed that all cases were in standard deviation less than ${\pm}3$ mm. It is judged that there is little result difference between focus mode and determination of three-dimension position by distortion model. Lastly the checkpoint performance by total station was fixed as most probable value and the checkpoint performance determined by each project was fixed as observed value to calculate statistics on residual of individual methods. The result showed that all projects had relatively large errors in the direction of Y, the direction of object distance compared to the direction of X and Z. Like above, in terms of accuracy for determination of three-dimension position for a close object, the feasibility to use smartphone camera would be enough.

Entrepreneurship based on valuable opportunities has a positive effect on long-term economic growth. This study examines the entrepreneurship education offered to small business entrepreneurs from the perspective of opportunity-driven entrepreneurship in order to suggest improvements and future direction for small business entrepreneurship education. Also, we tried to investigate entrepreneurial behaviors related to opportunity development more effectively by considering entrepreneurial self-efficacy and regulatory focus that play a crucial role in opportunity development process as mediating variables. Conducted was an online survey of small business owners nationwide who have completed entrepreneurship education provided by the government, and 345 online survey data were used for empirical analysis. The results show that entrepreneurship education for small business entrepreneurs positively influences entrepreneurial self-efficacy. Entrepreneurial self-efficacy is positively related to both opportunity recognition and evaluation as well as the promotion and prevention focus. Entrepreneurship education, which includes theoretically and practically oriented courses, has a positive impact on both the promotion and prevention focus. The promotion focus of small business entrepreneurs was found to have a positive effect on opportunity recognition, but not on opportunity evaluation. Also, the preventive focus of small business entrepreneurs does not have a significant effect on both opportunity recognition and evaluation. The current entrepreneurship education for small business entrepreneurs does not have a significant impact on their opportunity recognition and evaluation. These results suggest that the current entrepreneurship education for small business entrepreneurs needs improvements to promote opportunity-driven entrepreneurship.

The purpose of this study is to review empirical research on Form-focused instruction (FFI) in Korean language education from a critical perspective to better understand the effectiveness of FFI. To achieve this goal, several databases were searched to locate relevant experimental and quasi experimental studies published in peer-reviewed journals. Out of 66 studies collected, 12 studies met the inclusion criteria. The studies were then analyzed in terms of subjects, target grammar, treatment, measurement, and the learning outcomes of different techniques. In general, several types of FFI techniques had positive effects on helping learners acquire Korean as a second or foreign language. The results of the study will provide a conceptual framework which identifies the major factors affecting the effectiveness of FFI. The results will also be able to inform future meta-analytical research of existing studies.

The purpose of this study was to analyse the belief about mathematics teaching of elementary preservice teachers and mathematics teachers. This study involved 100 respondents from the preservice teachers and 114 respondents from the mathematics teachers. The instruments used in this study consist 15 items of mathematical knowledges and 19 items of mathematical activities. The finding showed that preservice teachers emphasized the conceptual knowledge, whereas mathematics teachers emphasized the procedural knowledge in the mathematical knowledges. And preservice teachers emphasized the knowledge representation, knowledge generation, knowledge deliberation, knowledge communication, whereas mathematics teachers emphasized the use of knowledge(syntax) in the mathematical activities. Finally, even though two groups showed the significant difference in some items, preservice teachers and mathematics teachers emphasized the various mathematical knowledges and mathematical activities.

The purpose of the present study was to investigate the role of self-regulated learning and academic burnout on the relationship between regulatory focus and academic achievement. The participants of this study were 312 university students and analyses for this study was conducted by using PASW 18.0 and Amos 8.0. The major achievements were as follows; Self-regulated learning confirmed mediating variable between regulatory focus and academic burnout, and academic burnout confirmed mediating variable between self-regulated learning and academic achievement. That is, regulatory focus had some effect on academic achievement through academic burnout based on self-regulatory learning. Finally, the needs of development about the counseling and the education approaches as a special intervention was discussed, and that approaches were reflected self-regulated learning to be improved and academic burnout to be reduced. Also, limitations and implications of subsequent further study were suggested in this research.

The purposes of this study is examining a wearing tendency of a progressive multifocal lens. We measured refractive error values using subjective and objective refraction method with subjects in 40-65 ages. Also, we investigated and analyzed distribution of addition power and wearing tendency of progressive multifocal lens. Detected addition powers were ranged of +0.75D - +3.00D. In case of average addition, they were detected with +1.18D in 40's, +1.55D - +1.97D in 50's and +2.38D in above 61's age. The distributions of visual ability at a distant were measured that the hyperopia and hyperopic astigmatism 43%, the myopia and myopic astigmatism characteristic astigmatism 7% appeared highly with 36%. The male who uses the interior aspect multi focal lens with the short-range work were appeared the male 20%, the woman 19%.

In this study, the intellectual structure of Records Management and Archival Science in Korea was analyzed based on the syntactic and semantic structure analysis of article titles. The data used in this study were 344 articles from three major representative journals in the field of Records Management and Archival Science, published from 1999 to 2008. The results of the syntactic and semantic structure analysis of article titles show that the three role concepts of keywords are 'research domain', 'research object', and 'research focus'. Keywords in article titles were clustered into the core subject areas after they were assigned three concepts. Based on the results of cluster analysis, the intellectual structure of Records Management and Archival Science in Korea was proposed.

도서관 정보시스템에 대한 평가 논문중에서 최종이용자를 대상으로 하여 검색기능의 성능을 평가한 논문은 많이 볼 수 있으나, 또 다른 이용자 계층인 사서를 대상으로하여 업무를 수행함에 있어서 전산화가 작업효율성에 어떠한 영향을 미치는지에 관한 소프트웨어 평가논문은 미비하다고 할 수 있다. 따라서 본 연구는 도서관 정보시스템의 또 다른 이용자 계층인 사서에 초점을 맞추고, 사서의 작업행태를 조사분석하여 소프트웨어의 보완점과 개선점을 파악하여 업무의 효율성을 높이고자 한다.
