The software complexity model makes an estimated of the product software. For a practice of software managed, need to guideline of the static analysis. Especially, Software complexity model introduced for the estimation of software quantity. In case of measurement the software matrices, its need for us to analysis of software qualify and products. In this paper, we represent that the analysis of function point, control structure and interface, volume matrices in various aspect of switching software. Others, their results utilized similar of project and system development.

국제 해상물동량(해상화물 수송량은 10년 사이에 매년 평균 4.3%씩)의 증가에 따라 해양사고의 발생 빈도도 높아지고 있으며, 사고의 규모도 대형화 되고 있는 추세이다. 이에 따라 해상에서의 선박 위험도 저감을 위한 많은 시스템들이 개발/운영되고 있지만, 대부분 실시간 위치정보를 기반으로 충돌위험 등을 분석하고 있고, 선박간의 충돌 외의 선박의 주변 환경에 대한 고려는 미비한 실정이다. 실제 해상에서의 통항량 및 10년간 사고를 분석하여, 충돌등 사고가 많은 남동부 해역(여수/통영/진해)의 통항패턴, 교차구역 및 해양사고 특성을 분석해보고, 이에 따라 Sector별 특징적 집중 관제 방안을 마련하여, 선제적 안전 서비스 방안을 연구하고자 한다.

Types of slope failure related to cut slope stability are interpreted through case analyses, and also factors affecting structurally controlled instability investigated, which are developed by geologic structures along a national road No. 25 across the Cheongwon and Boeun-Guns, Chungbuk. Engineering properties such as orientation, persistence, roughness and uniaxial compressive strength of joints are analyzed by square-inventory method in three areas with well-preserved outcrops. The study area is located in Ogcheon folded bet, and are composed of quartz-schist and quartzite in the Midongsan Formation and phyllite in the Ungyori Formation. Flexural beds by folding, schistosity and cleavage besides joints are developed due to slight metamorphism. Various types of joints developed by folding are formed such as strike-parallel, strike-perpendicular, wedge and wrench joint sets by both initially regional and later superposed folding. Factors of slope instability are created by crossing the orientations of joint, cleavage, bedding and slope one another. In the case that the orientation of a slope is coincident with one of beds, factors causing large-scale failure including plane failure are increased greatly. Also in the region that orientations of the slope and bed are crossed each other at high angle, only local and minor failures are shown in the slope.

This case study was carried out for the purpose of surveying the awareness of safety and safety education among students in a technical high school, in order to provide the basic data for the effective education of technical high school students' safety management consciousness. The study was carried out using a questionnaire survey for which the respondents were 455 students. The results of the questionnaire were subjected to statistical processing, such as frequency analysis using SPSS for Windows version 19.0. The reliability of the questionnaire in this study is Cronbach' = 0.871~0.882. According to the survey results, the students think that the contents of the school safety education would not be of interest to them and that safety education in school would help their school life, but not be useful for their daily life.

This study aims to examine the cases of overseas experience programs centered around middle school students in South Korea and to derive implications for future overseas experience programs. To achieve this, data were systematically collected through search engines based on keywords, followed by comparative analysis. Frequency analysis, independent sample t-tests, and cross-analysis were conducted using SPSS 23. The research findings are as follows: First, the programs are operated nationwide, with a focus on smaller schools in various regions, and are particularly active in the Jeolla provinces. Diverse public funding, such as from the board of education and local governments, has been invested, categorizing operational costs into full financial coverage among others. The programs primarily took place in Southeast Asian countries close to South Korea. Second, the purposes of these middle school overseas experience programs largely encompass career exploration, cultural experiences, tourism, and sister school visits. We hope that school-based overseas career exploration programs are actively operated to provide opportunities for enhancing global competence and global citizenship, as well as exploring career paths.

The purpose of this study is to understand two geography student teachers' experience of practical knowledge on the geography classroom organization during their student teaching. I carried out a qualitative case study on the geography classroom organization and its practice. Data was gathered through participant observation and in-deep interview. The results are as follows: 1) I present portraits two pre-service geography teachers' lives, which represent typical case of intrinsic deep motivation and spontaneous interest in subject matter. 2) Their classroom are organized $9{\sim}14$ segment, its segment organizations in introduction close steps and main lesson step behave differently. The segment activities in close step behave most irregularly. 3) In the reflection rubric, the level of their reflection is middle, mostly concentrated on 'technical' or 'dialogue' level. On the basis of these findings, it can be concluded that a different way of understanding the relationship between knowing to teach and knowing about teaching is necessary.

A mineral potential map showing the distributions of potential areas for exploration of undiscovered mineral deposits is a kind of predictive thematic maps. For any predictive thematic maps to show reasonably significant prediction results, validation information on prediction capability should be provided in addition to spatial locations of high potential areas. The objective of this paper is to apply prediction rate curves to the estimation of prediction probability of future discovery. A case study for Au-Ag mineral potential mapping using geochemical data sets is carried out to illustrate procedures for estimating prediction probability and for an interpretation. Through the case study, quantitative information including prediction rates and probability obtained by prediction rate curves was found to be very important for the interpretation of prediction results. It is expected that such quantitative validation information would be effectively used as basic information for cost analysis of exploration and environmental impact assessment.

중국은 지난 10년간 아시아에서의 영향력 확대를 위한 팽창정책의 일환으로 인도양 주변 국가들과의 관계발전을 위해 국가 차원의 노력을 기울여왔다. '진주목걸이 전략(String of Pearls Strategy')으로 묘사되는 중국의 인도양 정책의 개괄적 성격에 관한 연구는 여러 학자들에 의해서 시도되어 왔으나, 인도양 주변 개별국과들과의 협력과 개입의 정도(The variation in the extent of China's Engagement and Collaboration with States along Its Indian Ocean sea lines of communication)에 영향을 미치는 구조적 요인에 대한 연구는 부재해 왔다. 이 논문에서는 인도양 주변 국가들에 대한 개입 및 관계발전을 위한 중국의 인도양정책을 국제정치학의 이론 중 '방어적 신현실주의(Defensive Neorealism)'의 이론적 틀에 근거한 '연성적 힘의 균형(Soft Balancing)'의 관점에서 고찰해 보고, 중국의 인도양 정책은 이 지역에서 중국의 팽창에 대한 미국의 견제 및 반발(Backlash)을 억제하고 중국의 에너지 안보를 보장하기 위한 전략적 정책의 결과임을 조명해 본다. 더불어 중국의 인도양 진출에 따른 미국의 정책대안을 예측해 본다. 본 연구의 목적을 위해 이론적 틀에 기반한 가설을 설정하고 인도양 주변의 11개 국가에 대한 교차 사례연구(Cross-sectional Case Analysis)를 통해 타당성을 검증한다.

This study was a drone-utilized case study motivated by that drones can obtain sophisticated video image data previously not feasible. The dilemma zones on selected intersection approaches were identified and locations of drivers' decision making to stop or go at the onset of yellow were determined by analyzing drone video images. The gap between the drivers' decision making location and invisible stop/go border line provided by the yellow time interval was defined as "risky passing zone". To improve the dilemma zone safety problems, re-optimization of yellow time intervals and introduction of new pavement marking that can help drivers decision making on yellow indication are suggested.
