J2EE/EJB 환경에서 컴포넌트 테스트 방법 개관

국승학,김현수 충남대학교 산업기술연구소 2005 산업기술연구논문집 Vol.20 No.1

컴포넌트 기술은 소프트웨어를 신속하고, 효과적으로 개발할 수 있는 대안으로 90년대 초반부터 각광을 받기 시작하였다. 이러한 컴포넌트 기술을 활용하는 컴포넌트 기반 개발 방법론이 현재까지 소프트웨어 산업에서의 새로운 대안으로 인식되고 있다. 현재 산업계에서는 컴포넌트 기반 개발 프레임워크 중의 하나인 J2EE를 적용한 개발이 많아지고 있다. 이는 J2EE가 단순히 컴포넌트 기반의 어플리케이션을 구현할 수 있는 수단이 될 뿐만 아니라 어플리케이션 개발 시 제공해야 하는 많은 서비스들을 J2EE 플랫폼을 통해 제공하기 때문이다. 그러나 J2EE 컴포넌트를 테스트하는 것은 기존의 자바 클래스의 테스트보다 더 많은 노력이 필요하고, 어려운 작업이기 때문에 많은 경우에 충분한 테스트를 수행하지 않는다. 많은 개발자들이 J2EE/EJB 컴포넌트를 개발할 때 고려해야 할 사항과 채택해야 하는 테스트 전략에 관해서 알지 못하기 때문이다. 이에 본 논문에서는 기존의 J2EE/EJB 컴포넌트 개발 시 고려해야 할 사항과 테스트 전략에 대해 살펴본다. Component technologies which enable quickly and effectively to develop softwares have begun to come into the spotlight since early 1990s. Nowadays a component-based development methodology using the component technologies is recognized as a new alternative to improve productivity in the software industries. Currently, a number of software development works are performed on a J2EE environment, one of component-based development frameworks. This phenomena arises from J2EE's versatility. A J2EE framework provides plentiful services required to develop component-based softwares. Thus the developers only concentrate on the implementations of business logics. But component testing is a very difficult task since it requires more efforts than the previous Java class testing. So many developers do not perform enough testing works. In fact, many developers do not know about considerations needed to implement EJB components and testing strategies used to verify the components. This paper introduces systematically testing strategies for EJB component test.

In this thesis, Multi-way branch structure is designed to execute multiway branch instruction in the wireless LAN protocol processor. Because this structure substitute CAM(Content Addressable Memory) for target selection unit with label index information of program which branch in multiway according to system variables consist of flags & vectors. The CAM store a set of arbitrary variable conditions. Thus, this structure have feature which assign system value for multiway branch, can programming and reconfigure a set of variable conditions. The Desing of Multiway branch structure used cmn8a library which is 0.8um process of Compass tool, have about 9,500 gates and suitable for basis clock 80MHz of wireless LAN protocol processor.

위암 환자에서 세포성 면역 기능에 관한 연구

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

公示透明性이 企業成果에 미치는 影響에 관한 硏究

李弼商,柳國鉉 서울大學校經濟硏究所 2004 經濟論集 Vol.43 No.3

본 연구는 기업경영의 투명성을 기업내용공시의 투명성으로 정의하여 公示透明性指數가 企業成果에 미치는 영향을 분석하였다. 분석결과, (1) 공시투명성지수는 市場價値 대 帳簿價値比率(MBR)과 정(+)의 유의적인 상관관계를 보여, 공시투명성지수가 높은 기업이 시장에서 높게 평가받고 있었다. (2) 공시투명성지수는 외국인투자자지분율과 정(+)의 유의적인 상관관계를 보여, 외국인투자자들이 공시투명성을 중요한 투자판단기준으로 고려하고 있다는 것을 보여 주었다. (3) 공시투명지수는 대주주1인지분율과 정(+)의 상관관계를 보였다. 이는 외국인투자자들의 감시와 기업지배구조제도의 정착 및 공시위반에 대한 제재강화로 대주주의 불공정행위 유인이 통제되고 있는 데 따른 것으로 보인다. (4) 공시투명성지수는 일일주가수익률의 연간변동성과 부(-)의 유의적인 상관관계를 보여, 공시투명성지수가 높은 기업은 주어진 정보에 대하여 주가가 덜 과민하게 반응하는 것으로 나타났다. 상기의 결과는 우리나라에서 개별기업의 공시투명성 차이가 기업내용에 대한 신뢰도와 평가 차이로 이어지는 등 공시투명성에 대한 시장기능이 작동하고 있다는 것을 나타내 주고 있다.

Goals and Contents of Social Ethics Education in Korea

( Kuk Hyeon Kim ) 한국윤리학회 2015 倫理硏究 Vol.101 No.1

The aim of this paper is to discuss goals, contents, and new orientation of Social Ethics Education in Korea. For this aim, the definition of concept of social ethics, changes of learning theme of Social Ethics Education of Korean Moral Education Curriculum, and educational tasks for more effective implementation of Social Ethics Education in High School are discussed. Firstly, to define concept of Socia Ethics and Social Ethics Education focused on its constructs, aim, values, principles. Secondly, to analyze Moral Education Curriculum from The Fifth Moral Education Curriculum to Newly developing Moral Education Curriculum that will be implemented from 2018. Curriculum Analysis is focused on goal, principles, core values, objectives, and contents of Social Ethics Education on the Korean High School. Thirdly, to discuss educational tasks of Social Ethics Education such as learning materials development based on Korean ethical thought and life history or narratives of Korean which are past life experiences under unfair and corrupt social structure. The aim of Social Ethics Education has been to educate student as moral agent who has moral responsibility for making social structure fair. In Newly developing Moral Education Curriculum, Social Ethics Education on High School will be implemented through three courses such as ‘Ethics and Thought’, ‘Life and Ethics’, ‘Classics and Ethics’. They include learning theme such as a climate justice, the duty of foreign aid, terrorism and war as Global Social Ethics. And ethical inquiry and ethical reflection on morality of social structure and individual morality to groups, institutions, policies as social persons are emphasized as effective teaching and learning methods of Social Ethics Education.

Analysis and Improvement Direction of Unification-related Contents in Moral Education Textbooks of Secondary School

( Kuk Hyeon Kim ) 한국윤리학회 2015 倫理硏究 Vol.104 No.1

This paper analyzes Unification related contents in Moral Education Textbooks of Secondary School and suggests improvement directions of textbook organization and learning theme for Unification. The 2015 liberal art and natural science integrated curriculum was announced in last August. This curriculum will be implemented in schools starting from year 2018. Even though the new curriculum is announced, studies to improve the curriculum must be conducted continuously. The first to consider under circumstances of writing new textbooks in terms of the new curriculum is to set rational directions to improve textbooks and to deduct improvement points according to the critical analysis of the current textbooks. This paper deals with environmental analysis of unification education in moral education, criteria that can be applied in analyzing unification-related contents in current moral education textbooks, and improvement directions in terms of moral education based on results of analysis.

Nonlinear semigroups on locally convex spaces

Hyeon, Son-Kuk The Youngnam Mathematical Society Korea 1990 East Asian mathematical journal Vol.6 No.1

Let E be a locally convex Hausdorff space and let $\Gamma$ be a calibration for E. In this note we proved that if E is sequentially complete and a multi-vaiued operaturA in E is $\Gamma$-accretive such that $D(A){\subset}Re$ (I+$\lambda$A) for all sufficiently small positive $\lambda$, then A generates a nonlinear $\Gamma$-contraction semiproup {T(t) ; t>0}. We also proved that if E is complete, $Gamma$ is a dually uniformly convex calibration, and an operator A is m-$\Gamma$-accretive, then the initial value problem $$\{{\frac{d}{dt}u(t)+Au(t)\;\ni\;0,\;t >0,\atop u(0)=x}\.$$ has a solution $u:[0,\infty){\rightarrow}E$ given by $u(t)=T(t)x={lim}\limit_{n\rightarrow\infty}(I+\frac{t}{n}A)^{-n}x$ each $x{\varepsilon}D(A)$.
