Can we use the open innovation paradigm in Korean economy? Can Korea move from imitative national innovation system to Creative national innovation system without open innovation paradigm? We are looking for preliminary answers about these questions. In this paper, first of all, we review the theoretical factors of open innovation originated from professor Chesbrough, try to find out the limit of the theory, and propose the possibility of extending of open innovation from company to industrial sector, region and cluster, and national innovation system. We also review the user innovation models from Von Hippel and open business models. Second, we review the Korea open innovation cases according to the categories like as company, sector, cluster and regional innovation system, and national innovation system. Third, we prepose the theoretical and realistic implications, and next research agenda about Korea open innovation.

On this research we investigated variables affecting university students' time management and verify relationship between the time management and life satisfaction. 438 students at Korea National Open University in Seoul were questioned through questionnaires composed of 47 questions. Data was analyzed by t-test, one-way ANOVA, Duncan's multiple range test and Person's correlation. The variables affecting time management were religion(those who believe in organized religion vs. those who do not), individual income, family income, teaming experiences for time management and reading books related to time management. fender, age, marriage status and occupation didn't affect the time management of students. The relationships between time management and life satisfaction showed a little positive relation. Some proposals for future researches and practices are given.

To isolate the $\beta$-galactosidase producing thermophilic bacteria, samples of mud and water were collected from hot springs of avolcanic area near Golden Springs in New Zealand. Among eleven isolated strains, the strain of KNOUC112 produced the highest amounts of $\beta$-galactosidase at 40 h incubation time (0.013 unit). This strain was aerobic, asporogenic bacilli, immobile, gram negative, catalase positive, oxidase positive, and pigment producing. Optimum growth was at 70-72$^{\circ}C$, pH 7.0-7.2, and it could grow in the presence of 3% NaCl. The main fatty acids of cell components were iso-15:0 (30.26%), and iso-17:0 (31.31%). Based on morphological and biochemical properties and fatty acid composition, the strain could be identified as genus Thermus, and finally as Thermus thermophilus by phylogenetic analysis based on 16S rRNA sequence. So the strain is designated as Thermus thermophilus KNOUC112. A gene from Thermus thermophilus KNOUC112 encoding $\beta$-galactosidase was amplified by PCR using redundancy primers prepared based on the structure of $\beta$-galactosidase gene of Thermus sp. A4 and Thermus sp. strain T2, cloned and expressed in E. coli JM109 DE3. The gene of Thermus thermophilus KNOUC112 $\beta$-galactosidase(KNOUC112$\beta$-gal) consisted of a 1,938 bp open reading frame, encoding a protein of 73 kDa that was composed of 645 amino acids. KNOUC112$\beta$-gal was expressed as dimer and trimer in E. coli JM109 (DE3) via pET-5b.

Open access is a paradigm whereby the electronic versions of scholarly publications are made freely accessible without any restrictions. It is actively promoted globally and is also promoted domestically in accordance with this global trend. However, there is a growing need to evaluate existing activities and to seek policies for the steady spread of open access. This study examines the necessity of switching to a national repository from existing institutional repositories through policy direction analysis of open repositories. We examined domestic open access policies by analysing various overseas cases and the situation in South Korea. Finally, we determined the validity of investment in a national repository by analysing its social and economic impacts using the modified Solow-Swan model. The main parameters for applying the modified Solow-Swan model were estimated, and the domestic research and development expenditure was predicted via a regression method. Then, we applied a range of rate of returns to research and development (10% to 50%) to various scenarios and examined the effects of increasing accessibility and efficiency by 1% to 10%. We found that the implementation of a national open access repository in South Korea would have a substantial impact (to the tune of 147 billion won), without considering the potential costs of such a repository. Based on the estimates of the social and economic impact of a national repository, the implementation of a national open access repository in South Korea is economically viable. Besides having beneficial social and economic impacts, a national repository is expected to enhance awareness of open access among Korean researchers and institutions.

2.0 시대에 도래하면서 웹에 대한 새로운 패러다임이 생성되었다. 이러한 웹 2.0의 주요 기술은 OpenAPI인데, OpenAPI는 간단한 프로토콜로 정의되어 사용되기 때문에 많은 사용자들이 손쉽게 서비스를 만들 수 있는 장점이 있다. 하지만 빠르게 증가하는 OpenAPI를 효과적으로 검색할 수 있는 여전히 연구중이다. 본 논문은 이러한 OpenAPI에 대해 키워드 기반 검색보다 한단계 발전한 시맨틱 기반의 검색을 제공하기 위해 관련 표준 및 기술에 대해 설명하였다. 이러한 시맨틱을 활용한 OpenAPI의 검색기법은 OpenAPI를 통해 많이 사용되는 매쉬업(Mashup)을 위한 서비스 검색에도 활용될 수 있다.

최근 컴퓨터 비전의 활용 영역이 증가함에 따라 컴퓨터 비전의 대표적인 라이브러리인 openCV의 사용 또한 증가하는 추세이다. openCV 에는 컴퓨터 비전 알고리즘의 특성상 massive 한 연산을 수행해야 하는 부분이 상당수 존재한다. 본 논문은 이러한 연산량의 부담을 줄임으로써 openCV 의 성능 향상을 위한 아키텍처를 연구한다. openCV 의 massive 한 연산은 라이브러리 함수에 있는 내부 반복문에서 발생하기 때문에, 본 논문은 반복문의 특성을 분석하고 이를 가속할 수 있는 아키텍처가 무엇인지 연구한다. 결론적으로 반복문의 각 iteration 이 독립적일 경우에는 SIMD (Single Instruction Multiple Data)와 SIMT (Single Instruction Multiple Thread)이 적합하며 반복문의 각 iteration 이 의존적일 경우에는 MIMD (Multiple Instruction Multiple Data)를 바탕으로 하는 파이프라인 아키텍처가 적합하다.

OpenAPI와 매쉬업(Mashup)은 현재 발전해가고 있는 웹 2.0을 이루는 중요한 기술이다. OpenAPI의 수는 기하급수적으로 증가하고 있기 때문에, OpenAPI에 대한 검색시스템은 반드시 필요하게 되었다. 대표적인 OpenAPI 검색은 Programmableweb과 Popfly에서 제공하고 있으며, 이들의 제한점을 보완한 OpenAPI 검색 시스템이 연구되고 있다. OpenAPI 검색 시스템은 웹서비스 검색 시스템을 확장하여 개발되었지만, 다양한 OpenAPI의 프로토콜을 지원하지 못한다. 따라서 본 논문은 효과적인 OpenAPI 검색 시스템에서 OpenAPI의 다양한 프로토콜을 포함할 수 있는 통합 정보모델을 구축을 목표로 한다. 개발된 OpenAPI 통합모델은 OpenAPI 및 매쉬업 가능 서비스 검색에 활용될 수 있다.

A book of brief records of open heart surgery underwent between 1959 and 1982 at Seoul National University Hospital was recently found. The book was hand-written by the late professor and cardiac surgeon Yung Kyoon Lee (1921-1994). This book contains valuable information about cardiac patients and surgery at the early stages of the establishment of open heart surgery in Korea, and at Seoul National University Hospital. This report is intended to analyze the content of the book.
