정동원 ( Dong Won Jeong ),한종호 ( Jong Ho Han ) 한국물류학회 2012 물류학회지 Vol.22 No.2

물류산업은 경제 발전에 중요한 역할을 담당하며, 산업경쟁력과 국가경쟁력을 결정하는 중요한 요소로 작용하고 있다. 본 논문에서는 산업연관분석을 이용하여 물류산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 물류산업의 타 산업 생산유발효과, 부가가치 유발효과, 취업유발효과를 살펴본다. 다음으로 상대적으로 복잡성 때문에 잘 사용되지 않았던 공급유도형 모형 및 레온티에프 가격모형을 적용하여 물류산업의 공급지장효과 및 물가파급 효과를 살펴본다. 이러한 분석은 모두 물류산업을 내생부문이 아닌 외생부문으로 다룸으로써 물류산업을 중심으로 이루어지게 된다. 주요 분석결과를 요약하면 다음과 같다. 물류산업의 1원 생산은 타 산업의 생산을 0.5104원만큼 유발하며, 타산업의 부가가가치를 0.1722원만큼 유발한다. 또한 물류산업의 10억원 생산은 타산업에서 2.2554명의 취업을 유발한다. 한편 물류산업에서 1원의 공급이 이루어지지 못할 때, 타 산업에서는 0.9387원의 생산차질이 발생하여 공급지장효과가 제법 큰 편이다. 마지막으로 물류산업의 가격이 10& 상승했을 때, 국민경제 전체적으로 미치는 물가파급효과는 0.0276%로 분석되었다. The logistics industry in Korea plays a major role in the national economy development and to make decision nation and industrial competitiveness, This study attempts to examine the economic impacts of the logistics industry using an inter-industry analysis, Specially, the study investigates production-inducting effect, value added inducing effect, and employment-inducing effect of the logistics industry based on demand-driven model. Moreover, the study deals with supply shortage effect and sectoral price effect by using supply-driven model and leontief price model, respectively, which have been rarely used because of their complications involved in computaiton. These analyses pay particular and close attention to the distribution industry by taking it as exogenous rather than endogenous. Some interesting findings emerge from the study. First, the production of 1.0 won in the logistics industry induces the production of 0.5104 won and the value-added of 0.1722 won in other industries. Second, the production of 1.0 billion won in the logistics industry causes the employment of 2.554 persons in other industries. Third, the supply shortage of 1.0 won in the logistics industry disables other industries to produce 0.9387 won. Finally, an increase of 10% in price level of the logistics industry raises the overall price level by 0.0276%.

원동희,이민기 國立 昌原大學校 産業技術硏究所 2002 産技硏論文集 Vol.16 No.-

In this paper, we deveop a six-axes machining center tool(MCT) and CAD/CAM system. The MCT consists of two mechanical parts, i.e., a X-Y-Z Cartesian coordinate typed MCT and a parallel-typed tilting table. Kinematics and singularity are accomplished to design the parallel-typed tilting table, and CAD/CAM system is developed for the six-axes MCT, which requires the commands of position as well as orientation for machining of complex shape. The CAD/CAM system has a tool path generator, a NC code generator and a graphic simulator. This paper designs the parallel-typed tilting table to meet the desired specification and present the results of tool path, NC code and graphic simulation.

A CAD system used in current industry is very various, and is each different in form establishing in a design, interpretation, processing part according to a characteristic of program to need in a company and is on a distribution. It is necessary for to try do an analysis on data exchange between each CAD System in this misgovernment. Let's look into a car, a ship, an aspect of a CAD System using in a representative enterprise of an airplane field. Because a customer enterprise is spending an expensive program to have a great deal of merits in a customer enterprise It will be going to match sub vendors in a program of a customer enterprise, but it draws sub vendors and cannot become a lot of assistances. Therefore, it is the trend that sub enterprises convert the Data which used each other program, and exchange information. It will be heard in various demands and CAD technology to change suddenly, data exchange with an enterprise of a consumer by production, and before a great deal of engineering changes are asked. A great deal of study is necessary on data exchange it is the conversation that a lot of enterprise is mutual, and to be able to play.

元東豪 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.1

We propose a new method for constructing the public-key cryptosystem which is consisted of nonsingular matrix and nonlinear equations to be elements in upper triangular matrix over GF(P). The encipher key and the decipher key can be easily obtained with the multiplication of matrices over GF(P). We verified the new public-key cryptosystem with a small example of the order 4 of a nonsingular matrix over GF(17).

Trichoderma viride에서 분리한 Endoglucanases와 Cellulose의 상호작용에 있어서 Enzyme에 존재하는 Trytophan기의 역할

원성미,장영훈,김동원,정영규,류해일 공주대학교 사범대학 과학교육연구소 1996 과학교육연구 Vol.27 No.1

곰팡이 Trichoderma viride 셀룰라아제로부터 세가지의 endoglucanase (endoglucanase Ⅰ,Ⅱ및Ⅲ)가 다양한 크로마토그래피 과정을 통해 분리되었다. 또한 활성에 미치는 tryptophan기의 역할을 화학적 변형을 통하여 알아보았다. N-bromosuccinimide에 의한 효소의 화학적 변형으로부터, endoglucanase Ⅰ,Ⅱ및Ⅲ의 분자당 지니고 있는 tryptophan의 개수가 각각 6,1,1.5개 임을 알수 있었다. 즉 endoglucanase Ⅰ은 분자당 여섯 개의 tryptophan을 함유하고 있으며, 활성부위에는 한 개가 영향을 미치는 것으로 나타났다. 반면에 endoglucanase Ⅱ및Ⅲ는 분자내에 대략 하나의 tryptophan이 단지 활성부위에서만 작용하는 결과를 보여주었다. 또한 endoglucanase Ⅰ의 경우 활성부위가 아닌 다른 부분에 있는 tryptophan기가 기질의 표면에 흡착하는데 미치는 영향을 알아보았다. Three endoglucanases (endoglucanase Ⅰ,Ⅱ and Ⅲ ) as major cellulase components were isolated from the fungus Trichoderma viride by a of chromatography procedures, and the role of tryptophan residues in the activity towards carboxymethyl cellulose were investigated through kinetic and chemical modification studies. Through the modification of cellulase with N-bromosuccin-imide, it was found that endoglucanase Ⅰ,Ⅱ and Ⅲ contained 6, 1, and 1.5 tryptophan residue(s) per enzyme molecule, respectively. From the result of the kinetic data on the modification, it was estimated that the active site of enzyme includes at least one or two tryptophan residue. These results indicated that, in the case of endoglucanase Ⅰ, five tryptophan residues are exposed to another region of the enzyme except that of active site. In the case of the endoglucanase Ⅱ and Ⅲ, however, tryptophan residue exists almost in the active site. In addition, the relationship between endoglucanase activity towards cellulose and the role of tryptophan residue exposed to the enzyme surface was discussed.

한국의 가족주의적 전통이 직장내 인간관계에 미치는 영향에 관한 연구

이동원,함인희 이화여자대학교 한국문화연구원 1992 韓國文化硏究院 論叢 Vol.60 No.2

This paper begins with two questions. One is that, does the "Familism", a typical social character of the Korean people, affect the interpersonal relations in work organizations? The other question is that, how does the "Familism" work? Does it positively(or negatively) work in the formal organizations? If it does, why does it so? As we raised these questions, we have hidden agenda. One is related with the measurement issue, the other is more theoretical one. "Familism" has been regarded as the basic cultural values and has provided a guideline for the proper behavioral code to the Korean. However, the academic works dealing with the idea of familism hardly raised a question of how to measure it. Measurement of the concept like familism, which reflects multifaceted realities and includes various levels of analysis, is quite tricky. Here, we decided to focus on the two levels : familism as the normative values internalized into the individual, and as an actual behavior enacted by the individual. We made a list of "familism-oriented norms and behaviors". It includes the following items ; 1) respect the old 2) obey the old 3) patrilinear succession 4) strict division of labor along the lines of age and sex 5) hierarchical odering between sexes 6) paternalism 7) authoritarian character 8) collectivism is superior to individualism etc.. The lists are composed of 13 items of normative aspects and 8 items of behavioral ones of familism. 4 scores of Likert Scale is used to measure the degree of familism. As a next step, we applied the list selected from the family setting to another setting, work organizations. Following the same processes, 13 items of normative and 11 items of behavioral code were made. Second hidden agenda is more puzzling. If we assumed that the familism represents the Korean traditional heritage, work organization the modern western style rationality, then the interpersonal relations within the work organizations must be a good social structural context to show us how traditionality and modernity have met with. Many scholars demonstrate their regrets that the conflict between traditionality and modernity has produced current such social problems as generational conflict anomie social disintegration etc… On the other hand, a new perspective captures the crush of two forces with very different angles. Familism and industrialism have showed a sort of selective fitness in the rapid industrialization and urbanization processes since 1960s in the Korea society. Modern industrialized way of life has necessarily exerted a life strain. Within this stressful life situation, familism has helped people to adjust a new life conditions by giving motivation to work hard for their families well-being, and giving the heaven to homeless mind. On the purpose of testing these concerns, we tried to the empirical survey with a questionnaire. The survey was held from April 20th to May 4th in 1992. The sample was collected by the quater sampling. Total 681 cases were included into the final analysis. As the statistical methods, we mainly used the break-down(one of the ANOVA) technique. Respondents backgrounds are ; female is 38.2%, male 61.8%, age under 30 is 51.1%, 30-39 is 30.2%, over 40 is 18.7%, education level under senior high school is 27.1%, over 2-year college 72.9%, subjective evaluation of stratification is upper-middle 14.7%, middle-middle 57.7%, lower-middle 22.0%, and the type of work organizations is small-, medium-size corporations 21.0%, large corporations 27.8%, bank or other financial organizations 23.8%, civil officers 27.5%. The summary of survey results is : 1. We found out that familism as the traditional cultural values and the guidelines of behavior has a strong influence on the working lives and interpersonal relations within the work organizations. For example, more than 75% of respondents were seeking after the primary relationships even with the formal jog settings. Moreover, the main reason to work is based on rather relational value than individual one, that is, getting credit from the significant others and feeling of belongingness were more frequently mentioned as the reason than the income, self-actualization or success in their job. 2. We noticed that most respondents have an expectation of fatherliness to their manager or owner of the corporation. When we asked the desirable leadership style, 61% of respondents answered competent and rational decision-maker as the first quality of the leadership though, many respondents chose such family-oriented quality as having intimate relation with or taking care of the lower level members as their desirable leadership style. Overall, male, over age 40s older generation showed more familism-oriented values and behaviors than female, under age 30s younger generation. But, we could not find any consistent pattern of familism in regard to the type of work organizations. 3. We also confirmed that traditionalism and modernism have to some degree the selective fitness. The more the degree of adopting familism-oriented norms or values, the higher the level of satisfaction with the interpersonal relationships between colleagues and/or higher officers. As usual, this paper began with the questions to solve, but remained more questions to be answered. The potential conflicts along the line of sexes and generations, which are now emerging in the various work organizations, the more desirable patterns of integrating our traditional ethos with modern rationality within the formal organizations wait for next project.
