The aim of this study is to survey and analyze the recognition of teachers and students about methods for entering general high school. For this study, firstly current methods for entering general high school of 16 offices of education were compared and analyzed. Secondly recognition of teachers in middle school or high school and of students in middle school about methods for entering general high school were surveyed and analyzed. Major consequences of this study are as follows: Firstly, most teachers preferred the method by both school life records and the entrance test but most students preferred the method by school life records. Secondly, teachers recognized the difference of school life records according to sex and school and the decrese of academic achievement from decrese of motive for studies as serious problems of general high school entrance method by school life records. Thirdly, students recognized competition among students in the same school and the difference of school life records according to sex as serious problems of general high school entrance method by school life records.

This paper proposes on the technical blocking method of Internet harmful pornographic sites which is the most Internet negative-function. At Present, most technical methods based on web sites back-searching or words filtering for blocking the pornographic Internet sites have limitations. For this, this paper proposes the acoustic and image based blocking method for filtering harmful Internet sites. For this, sexual main body parts are extracted by texture analysis and curve fitting. Also acoustic signals are analyzed using pratt tool and auto-correlation function is adopted for matching between prototype signals and test signals. Finally, the effectiveness of this paper is demostrated by several experiments.

항공기 엔진 체계의 신뢰성과 안전성을 분석하는 것은 RAM 분석이라고 한다. RAM은 제작자가 개발한 시스템의 지속가능성 혹은 그 체계의 수명주기비용(Lice Cycle Cost)에 중대한 영향을 줄 수 있는 시스템 설계특성을 의미한다. 또한 RAM은 시스템이 개발될 당시에 의도된 임무를 수행할 수 있는 능력 혹은 임수수행을 성공할 수 있도록 담보하는 중요한 역할을 한다. RAM은 1970년대 이후 미국 군수분야에서는 군수지원성분석(LSA, Logistic Support Analysis) 과 밀접히 연계되어 활용되어 왔으며, RAM과 LSA를 통합하여 종합군수지원체계(ILS, Integrated Logistics Support)라고 부른다. 본 연구에서는 항공기 엔진에 대한 신뢰성 분석에 Weibull 분포를 활용하였다. Weibull 분포는 2개의 변수 적용에서 다음과 같이 정의된다. 변수가 그 계의 어떤 값을 나타내느냐에 따라 분포도 곡선의 특성 의미는 변수에 의존된다. 예를 들어 시험성적, 사회적 특성을 표현하는 인지도, 산업 제품의 고장이나 결함을 나타내는 고장관련 모수(변수) 등에 따라 그 특징을 나타내게 된다. 항공기 엔진의 신뢰성 분석을 통해 항공기 엔진의 수명 판단이 가능해졌으며 임무 불가능 수준의 In-Flight Shut-Down 비율이 현격히 감소됨을 확인할 수 있었다.

Purpose: This study aimed to evaluate the effects of sex education, focusing on the sexual activities of the elderly, on high school girls' sexual knowledge, attitudes, and perceptions. Methods: A quasi-experimental pre-post design was used, and the data of 82 participants (41 in each group) were analyzed. The educational effects were assessed through sexual knowledge, attitudes, and perceptions. The data were analyzed through SPSS 18.0, using descriptive statistics, chi-square tests, and paired t-tests. Results: The experimental and control groups had similar demographics. Sex education was effective in increasing sexual knowledge (p<.001), and changing the attitudes (p<.001) and perceptions (p<.001) of members of the experimental group for the better. Conclusions: This study has shown that sex education can improve high school girls' understanding of elderly sexual activities. This study is meaningful in that, it sought to facilitate a positive change in young people's attitudes towards elderly sexuality and quality of life.

In this study, we tried to represent representative animals in traditional dance and study about cultural symbolic representations that symbolize them, thus meaning Korean worship of animal worship and philosophy of life and discuss the identity of Korean traditional art. This is to ask fundamental questions about Korean culture and art, and to express the cultural philosophical reason for the representation of animal imitation. Therefore, Korean animal imitation dance was able to get a glimpse of Koreans' recognition of artistic value which is reflected in dance beyond simple cultural code. In other words, it was found that not only magic and sexual metaphors but also the adaptive attitude through natural friendly life and the ethical practice in reality were inspired by artistic aesthetics.

This study investigated the effects of situational context feedback in CAI upon students' conceptual understanding, science learning motivation, and the perception of CAI. Seventh graders (N = 114) from a coed middle school in Incheon were assigned to the situational context feedback CAI (SCF-CAI), the feedback CAI (F-CAI) and the CAI groups, and were taught about ‘three states of matter' and ‘motion of molecules' for 8 class hours. Prior science achievement test score used as a blocking variable. Two-way ANCOVA results revealed that the conceptual understanding test scores of the SCF-CAI group were significantly higher than those of the other groups. For the higher achievers, the scores of the F-CAI group in science learning motivation test were significantly higher than those of the CAI group. However, there was no significant difference among the lower achievers of three groups. The higher achievers in the SCFCAI and the F-CAI groups perceived the CAI more positively than those of the CAI group. The lower achievers in the FCAI group perceived the CAI more negatively than those of the other groups. Educational implications are discussed.

The power of human capital in a library is the main resource that determines the level of library services, which in turn should play a pivotal role in forming the intellectual power of the country. This research conducted a survey on the employment perspectives of LIS undergraduates, which resulted as follows. First, among the LIS undergraduates, 40% of students responded that their desire was to be employed in the library as librarians. Although there were some negative opinions regarding the working environment of the industry, the undergraduates appreciated the developmental possibilities. Second, the most desired task was working with cultural programs. Third, the respondents were satisfied with the current curriculum overall, acknowledging the extra need for job search support programs, which include career support, employment-related mentoring, and internships. Fourth, the main requirements for their future employability were perceived as grade point average, language skills, obtaining licenses, internship and apprenticeship experience, and career management. Fifth, influential factors on employment decision making were divided into two aspects: environmental and personal factors. The environmental factors included salary, welfare, opportunities in personal development, workplace environment, organizational culture, and development possibilities of the organization. The personal factors included fitness with personal aptitude, the level of knowledge and technology in the job industry, social norms and acknowledgement, rewarding opportunities with their major, and location of job.
