企業倫理의 提高

張益善 圓光大學校大學院 1989 論文集 Vol.4 No.-

From the viewpoint of business ethics, this thesis researched the internal and external factors of management, such as profit, advertisement, employee welfare, account, to conswmer, government, social responsibility and social welfare to uplift business ethics. The results are as follows: 1. As business ethics is applicable to various cases, it ought to be followed by the approach of situation ethics. 2. The managing staff ought to suggest a practical direction of enterprise ethics and create a necessary atmosphere. 3. The principle of business, ethics ought to be codified in order that it may be publicly communicated and concretized. 4. Business ethics ought to be enacted in order that between enterprise and those implicated in the interests of enterprise may obey social ethics and exist together. 5. Ethical virture ought to be rewarded, but vice, a wrong kind of ethics ought to be punished by a just system.

Airborne dust emission among construction industry place of work that locate on Pyeongtaek, Gyeonggi province of 4 processes (a plaster, cutting, hammer drill, concrete grinding) were analyzed. Work did in state that a worker does not exist except measurer as well as is not attained to control group. Investigation period did for 2 months from October to November. It measured 15 times by each process by personal air sampling method that is direct-reading particulate matter measurement device(digital dust indicator). When a plaster work, the dust was class 3 particulate matter, and geometric mean is 2.14㎎/m³, and occasion that exceed 10㎎/m³ that is threshold limit value was 13.3%. Control group was 0.35㎎/m³. plaster work was statisically difference higher than the control group (p<0.001). It was not significant difference between fixed type cutting machine work (0.96㎎/m³) and control group. It were not exceeded for threshold limit value. Geometric mean was 10.44㎎/m³ at movable type cutting machine process. Threshold limit value of this process was exceeded 53% and concentration of total dust was significantly higher than control group (p<0.001). Geometric mean was 3.22㎎/m³ at diameter 13.45㎜ drill work among hammer drill work and all cases not exceeded for threshold limit value, but it was significantly higher than control group(p<0.001). When work diameter 6.5㎜ drill, geometric mean was 4.06㎎/m³ and exceeded for threshold limit value was 13.3%, it was significantly higher than that of control group (p<0.001). It showed higher concentration of dust by diameter is smaller drilling. All 15cases exceeded threshold limit value at concrete grinding work, geometric mean was 78.38㎎/m³, and it was significantly higher than that of control group (p<0.001). As a result of above, countermeasure preparation that concentration of total dust by each process in construction workplace was specially required because exceeded threshold limit value of working environment more than 50% at process of concrete grinding work and movable type cutting machine.

목적 : 제일제당에서는 녹농균의 세포외막 단밸질을 유효성분으로 하는 백신인 CFC-101을 개발하였으며, 동물시험에서 이 백신의 안전성과 유효성을 입증하였다. 본 연구에서는 이 녹농균 백신의 인체에 대한 안전성과 면역원성을 평가하는 동시에 인체 접종시의 최적 투여 용량을 결정하기 위하여 제 I/Ⅱa상 임상시험을 수행하였다. 방법 : 건강한 성인 남자를 피험자로 선별하여 각 용량군에 백신투여자 6명, 위약투여자 2명을 배정하였다. 백신 투여군은 0.25mg, 0.5mg 또는 1.0mg 용량의 녹농균 백신을 7일 간격으로 3회에 걸쳐 근육주사 하였으며, 위약 투여군에게는 세포외막 단백질을 제외한 동일한 성분을 투여하였다. 백신접종 후 국소적 또는 전신적인 반응의 발생여부를 관찰하고, 혈액시료를 체취하여 백신의 역가와 유효성을 검정하였다. 결과 : 녹농균 백신 CFC-101은 모든 접종자에서 양호한 내약성을 보였다. 또한 0.5mg 과 1.0mg 백신 투여군에서는 100%의 항체양전율을 나타내었다. 생성된 항체는 녹농균 세포외막단백질에 특이성을 보였고, 녹농균 감염에 대해 방어효능이 있었다. 결론 : 이와같은 결과로부터 이 녹농균 백신은 인체에 안전하게 투여할 수 있으며, 높은 항체 생성능으로 감염방어 효능을 보이고 0.5mg과 1.0mg이 최적용량인 것으로 판단되었다. Background : We developed a Pseudomonas aeruginosa outer membrane protein(OMP) vaccine CFC-101, and the prophylactic efficacy of which has been demonstrated in animal models. In order to evaluate the safety and immunogenicity of the P. aeruginosa vaccine, we carried out a phase I/Ⅱa clinical trial in healthy male volunteers. Methods : Groups of eight volunteers, including two placebo subjects, were vaccinated intramuscularly with three doses of 0.25, 0.5 or 1.0 mg of the vaccine at one week intervals. Sings of systemic and local reactions observed after vaccination were recorded for each vaccinee for 5 days. Physical examinations were performed on days 0, 1, 7, 8, 14, 15, 21, and 42, and clinical laboratory tests were done on days 0, 3, and 21. Blood samples for assay of serum antibody levels were obtained up to 42 days after the first vaccination. Results : The vaccine was generally well tolerated by all vaccinees, showing no significant side effects. In the three dosage groups, all vaccinees, except one receiving the 0.25 mg dose, showed significant elevation in serum IgG antibody titers against the vaccine proteins, indicating 100% seroconversion in 0.5 and 1.0 mg groups. The human antibodies induced by the vaccine were specific for P. aeruginosa OMPs, as confirmed by western blot analysis and immunoprecipitation assays. The capacity of the human antisera to enhance opsonophagocytic killing activity by polymorphonuclear leukocytes and to confer protection against P. aeruginosa infections indicates that the antibodies elicited by the vaccine have protective efficacy. Conclusion : We conclude that the P. aeruginosa OMP vaccine is safe and effective for human use and its optimal dose to be 0.5 or 1.0 mg.

The soil hardness tester was developed in order to increase the accuracy of measurement and easiness of handling and make it possible to read the data continuously which might be impossible with conventional soil-hardness tester. A strain gauge and a potentiometer were mounted at cone penetrometer in this soil hardness tester. A series of soil hardness tests were conducted at the laboratory using this measuring system. And the results were compared with those obtained from cone penetrometer which was widly used for this purpose. Also, the soil resistance characteristics were investigated when cone, plate and cone-plate were tested, respectively. The following conclusions were drawn from the results: 1. The soil hardness tester developed in this experiment read data more accurately than cone penetrometer did, which was designed to read with dial gauge. Also, it made possible to read the data continuously as it penetrated from the surface to subsoil. 2. When cone, plate and cone-plate were penetrated into the test soil, soil hardness increased as depth increased gradually. Approximately at a 15㎝ of soil depth, the increase of soil hardness stopped and increased again as it penetrated deeply. This phenomenon seemed to be caused from soil resistance characteristic to penetration. 3. The desirable diameter of the plate seemed to be 50㎜ or more for measuring the surface hardness of the soil sample used in this experiment.

이장익 한국정보사회진흥원 2004 정보화정책 Vol.11 No.4

이 서평논문의 목적은 사이버강의 혹은 이러닝(e-Learning)으로 알려져 있는 대학교육의 정보화에 대한 이해와 향후 추진방향을 모색하기 위하여 대학교육의 정보화에 대한 전략적, 체계적 접근방법론에 대한 책과 함께‘학습자 지원(Learner Support)체제라는 중요하지만 다소 등한시되어왔던 개념에 대한 책의 내용을 소개?분석하는 것에 있다. 우선 Bates와 Poole의 Effective Teaching with Technology in Higher Education을 통해 대학에서의 교육정보화 추진과정에 대한 종합적 관점을 정리하였다. 저자들은 정보기술의 발전이 대학의 교육활동에 필연적으로 변화를 초래하고 있지만 교수와 학습활동에 대한 철저한 분석과 이해가 선행되어야 함과 동시에 대학조직의 전략적 발전목표와 교육활동의 정보화가 체계적으로 연계되어야 한다는 매우 상식적인 논리를 구체적 사례와 함께 단계별 방법론으로 제시하고 있다. 이들의 논점은 대학교육의 정보화에 대한 개념적 명료화를 시도하고 있으며 이러닝 프로젝트에 있어서 대학경영진의 철저한 리더십과 세밀한 경영전략의 중요성을 강조하고 있는 것에서 시사점을 주고 있다. 이어서 다룬 책은 Tait와 Mills가 편집한 Rethinking Learner Support in Distance Education이다. 이 책의 내용이 가지는 중요한 메시지는 다음과 같다. 첫째, 좋건 싫건 대학의 학습자는 이제 고객(customer)으로 인정되어야 한다. 둘째, 고객으로서 대학의 학습자를 인정한다면 학습자지원체제의 중요성은 더욱 높아질 것이며 온라인 학습환경에서 학습자 지원체제의 중요성은 핵심성공요소로 인식되어야 할 것이다. 셋째, 온라인 학습환경에서의 학습자 지원체제는 다양한 기술적 대안의 도입과 함께 기관차원의 적극적 지원을 통한 질적 향상노력을 통하여 온라인 학습환경의 문제를 해결하는 대안으로 자리잡을 수 있다. 이 서평논문은 두권의 책을 통하여 현재 우리나라 고등교육의 이러닝 도입 및 추진전략에 있어서 기관차원의 종합적 정책 및 기획역량과 함께 학습자 지원체제의 핵심적 중요성에 대한 시사점을 제시하고자 하였다.

통신프로토콜의 적합성시험열 생성을 위한 경로 탐색 방법

황익순,장민석,이상배,이재용 延世大學校 電波通信共同硏究所 1996 電波通信論文誌 Vol.2 No.1

본 논문에서는 적합성 시험에서 EFSM(Extend Finite State Machine) 모델에 대한 데이타부분 시험열을 효율적으로 생성시켜 주는 탐색 방법에 대해 제안하였다. 이 탐색 방법에서는 depth-first search와 같은 기존의 탐색 방법과는 달리 탐색 초기에 다양한 경로가 찾아진다. 이미 제안된 시험열 생성 방법인 데이타 값을 바탕으로 하여 시험열을 생성하는 방법에서 이 탐색 방법을 이용하였을 경우 기존의 탐색방법을 이용하는 것보다 효율적으로 시험열을 생성할 수 있다. 본 논문에서는 Inres 프로토콜에 이 탐색 방법과 기존의 탐색 방법인 depth-first search를 각각 적용하여 시험열을 생성, 비교하여 보았으며, 제안된 탐색 방법을 이용하면 같은 시험 범주를 가지면서도 짧은 길이를 갖는 시험열을 효율적으로 생성할 수 있음을 알 수 있다. In this paper we proposed a searching algorithm for generating test cases, which can test data part of EFSM model in conformance test. In a different way to existing algorithm like depth-first search algorithm, this one can find various paths in the early stage of searching. When it is used in readily proposed test case generation method which is based on the value of variables and parameters it can generate test cases efficiently than in the case of depth-first search algorithm being used. We generated test cases for Inres protocol using each of proposed and depth-first search algorithm, and compared these two methods. proposed algorithm can generate much shorter test sequences efficiently than existing one.

The pin-on-disk type wear testing machine was manufactured using a personal computer, load cell and reduction motor. The tribological properties of Ni-4.5%Al coating steel by flame spray were investigated using this test machine. The experimental result has shown that the wear amount of coating steel was remarkably decreased than the S45C material. In the lubrication environment the wear amount was much less. The friction coefficient of S45C and coating material was respectively 0.4, 0.29 in the air, and it has respectively shown 0.18, 0.24 in the lubrication. Increase of load didn't have effect on the change of the friction coefficient at all.

벤처기업의 성장 단계별 HRD모형 수립을 위한 기초 연구

이장익 한국직업능력개발원 2000 직업능력개발연구 Vol.3 No.1

This preliminary study is conducted based on some assumptions. First, explosive growth of venture-business does have profound and society-wide implications. Second, the venture-business model may thus serve as a guideline upon which we can use against the tidal wave of digital revolution. Third, from the point of HRD(Human Resources Development), venture-business practices are a valuable research material for innovative and effective HRD. Based on these assumptions, the purpose of this study was to analyse the conceptual relationships between HRD and venture-business model so that a future directions for HRD in digitalized environments might be proposed. First, this study attempted a synthesis of definitions for venture-business. On one side, venture-business denoted high-risk, high-return enterprises while another group defines it as a innovative and technology-intensive enterprises. The common elements were innovativeness, creativity, and knowledge-intensive small to medium business units. Second, available data on Korean venture-business map was analysed to confirm the definitions. Results indicate that Korean venture-business fit into forementioned elements of venture-firms. Third, a theoretical model of venture-business and HRD was proposed which argued that the venture-firms, HRD, and Knowledge management model all indicate a common objective as the strengthening of knowledge capabilities. Forth, this study attempted a verification of venture-HRD-knowledge management model by conducting a series of interviews with venture firm employees and managers. The results show that the model fits generally well with the venture-firm practices. In conclusion, this study provided that there are clear and critical interrelationships between HRD and venture which will influence each other's further development. Based on this preliminary study finding a recommendations for further studies were proposed.
