The purpose of the study was to examine the vocational educational system of Egypt, focusing on the effectiveness of the three consecutive cycle-based curriculum and integrated technical education clusters (ITECs) in order to suggest some implications for innovating the current vocational education system of Korea. The vocational education system of Egypt is similar to that of Korea, in terms of general education to go to university and vocational education to go to labor market. However, the Egyptian system is different from the system of Korea in light of the three consecutive cycle-based curriculum that links secondary vocational education, vocational education of college level, and advanced technical and vocational education. In addition, the Egyptian system has adopted the "cluster" approach which integrates technical secondary school, intermediate technical college, and advanced technical college around one physical area so as to promote vocational education in collaboration with regional industries and to guarantee education quality. In the last part, some potential implications were suggested for upgrading the quality of vocational education of Korea based upon the benchmark results of the Egyptian vocational education system and career development of students.

최근 인터넷 공간에서 사용자가 직접 만들어 내는 컨텐츠, 즉 UCC (user created contents, 이하 UCC)에 대한 관심이 그 어느 때보다 증가하고 있다. UCC란 기존의 온라인 컨텐츠 제공업자와 달리 일반 사용자에 의해 만들어져 게시판과 같은 도구를 사용하여 온라인 상에 존재하였다. 그런데 UCC 가 최근 들어 더욱 관심을 받고 있는 이유에는 사용자들이 직접 컨텐츠를 만들어 개제하는 것이 용이하도록 변화된 환경의 조성 및 컨텐츠 제작을 쉽게 할 수 있는 저작도구가 지속적으로 만들어지고 확산되었기 때문이다. 결과적으로 사용자 측면에서는 다른 사람들과 소통하는 통로가 확대되었고, 사업자 측면에서는 보다 컨텐츠를 풍부하게 확보할 수 있는 환경이 열린 것이다. 본 연구는 구비문학의 이론을 통하여 UCC의 활성화에 영향을 미치는 요소를 탐색적으로 살펴보는 것을 목적으로 한다. 구비 문학은 텍스트를 향유하는 사람들 사이에서 공유되는 이야기로서 그 생산 환경의 매커니즘과 텍스트의 발전 양상이 UCC와 매우 유사하다. 따라서 본 연구에서는 자료의 분석과 이론적 모형의 수립 과정 전반에 있어 구비 문학의 이론과 접근 방법을 사용하였다. UCC가 매우 활발하게 생산되는 주제를 선정하여, 그 주제에 해당하는 커뮤니티의 특성, 사용자들 간의 관계, 사용자 정책 등 차이가 있는 세 온라인 커뮤니티를 선정하였다. 선정된 온라인 커뮤니티의 게시판의 포스트와 댓글을 프로그램을 통하여 수집하고 분석하였으며, 그 분석된 데이터를 바탕으로 사용자를 선정하여 심층 인터뷰를 진행하였다. 심층 인터뷰 데이터는 근거이론은 이용하여 분석하였다. 본 연구의 결과는 UCC 확산이라는 새로운 인터넷 패러다임 속에서 이를 구비 문학의 이론으로 분석했다는 점에서 학문적 의의가 있다. 또한 성격이 다른 세 개의 사이트에서의 UCC를 비교함으로써 UCC를 기반으로 한 사이트 설계의 가이드 라인이 될 수 있는 실용적 의의를 가진다.

Objectives : The purpose of this study was to develop the Korean Strength Scale and to examine its validity and reliability. Methods : The Korean Strength Scale is a self-report questionnaire that measures 25 valued strengths and is comprised of 124 items ; each item had a 0-5 rating on a 6-point scale. In order to test validity and reliability, data were collected from 355 adults. The measures included the Korean Strength Scale, HEXACO Personality Inventory (HEXACO-PI), Satisfaction with life scale (SWLS), Positive Affect and Negative Affect Schedule (PANAS), and Orientations to Happiness Questionnaire (OHQ). Results : The resulting exploratory factor analysis of the Korean Strength Scale suggested 4 factor structures. The Korean Strength Scale was shown to have acceptable psychometric properties, including acceptable internal-consistency reliabilities, factorial validity, and high convergent correlations. Conclusion : Although there is room on improvement for some facet scales, the Korean Strength Scale appears to be a useful tool for assessing an individual's signature strengths.

To verify confidence of the measurement such as Firm performance of Entertainment system, Cronbach's alpha coefficient were measured and showed 0.7 or higher alpha values. Feasibility of the measurement is also ensured by exploratory factor analysis. This thesis are formulated and analyzed as two little hypotheses to make certain that systematization of entertainment company influences on the performance. As a result, the two hypotheses are significant influential factors on the performance of entertainment company. The result are somewhat predicted because it was constructed by theories and preceding research which the researcher had already recognized. But this study was conducted to provide suggestions to establish a theory of entertainment industry by active follow-up studies for resolving will-less different results in this field due to a lack of the proceding research. And it is required to be established through the academic interchange among the similar studies.

In my search of microbial source of novel enzymes, a marine actinomycetes, A1460, producing haloperoxidase was isolated from macroalgae from south sea, Korea and studied for physiological and biochemical properties. The haloperoxidation reaction was followed by the bromination of phenol red in the presence of hydrogen peroxide and potassium bromide. The haloperoxidase was partially purified from the cell extract with $35\sim75%$ ammonium sulfate precipitation, High-Q anion exchange chromatography, gel filtration chromatography, hydroxyapetite chromatography and hydrophobic interaction chromatography to a yield of 42% and purification fold of 70. This enzyme showed relatively high heat stability without losing 50% of activity after 1 hr incubation at $60^{\circ}C$. The highest activity was found at $45^{\circ}C$, and the optimal pH was about pH 7, but higher stability was observed at pH 8. Azide and cyanide ion showed strong inhibition at less than 1 $\mu M$ level suggesting that the enzyme was Fe ion dependent haloperoxidase.

Despite the importance of disaster management officers of disaster management agencies at the local government to protect the lives of civilians and their properties, there is a lack of research or literature in their roles and responsibilities. In fact, there is a urgent need to set clear roles and responsibilities for them. This study scrutinizes how to disaster managers should behave in specific setting that differentiates from other administrative managers based on domestic and foreign literature review. Although, the role of disaster manager seem to be similar to administrative manager, there are some differences particularly in the areas that disaster manager has to work as an expert in saving lives and properties that has to be further emphasized. When working on disaster management process of prevention and resoration, the key task are based on mid and low level officers. On the other hand, preparedness and response process that involve rapid decision making and cooperation with other department, persuasion of local residents and resource pooling are carried out by mid and high level managers because it requires control capacity and decision making skills.

Mashup is a web application that combines several different sources to create new services using Open APIs(Application Program Interfaces). Although the mashup has become very popular over the last few years, there are several challenging issues when combining a large number of APIs into the mashup, especially when composite APIs are manually integrated by mashup developers. This paper proposes a novel algorithm for automatic Open API composition. The proposed algorithm consists of constructing an operation connecting graph and searching composition candidates. We construct an operation connecting graph which is based on the semantic similarity between the inputs and the outputs of Open APIs. We generate directed acyclic graphs (DAGs) that can produce the output satisfying the desired goal. In order to produce the DAGs efficiently, we rapidly filter out APIs that are not useful for the composition. The algorithm is evaluated using a collection of REST and SOAP APIs extracted from ProgrammableWeb.com.

In this paper, we propose the Min-hash Assisted Delta-compression Engine(MADE) to improve the lifetime of NAND flash-based storages at the device level. MADE effectively reduces the write traffic to NAND flash through the use of a novel delta compression scheme. The delta compression performance was optimized by introducing min-hash based LSH(Locality Sensitive Hash) and efficiently combining it with our delta compression method. We also developed a delta encoding technique that has functionality equivalent to deduplication and lossless compression. The results of our experiment show that MADE reduces the amount of data written on NAND flash by up to 90%, which is better than a simple combination of deduplication and lossless compression schemes by 12% on average.
