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%.

Background : The aim of this study was to determine the clinicopathologic factors influencing to develop breast carcinoma followed thyroid carcinoma. Particularly we want to determin whether the adjuvant radiation therapy was related to development of thyroid carcinoma. Methods : There were 17 patients with breast carcinoma and thyroid carcinoma who registered at University of Kosin medical center between 2002 and 2007. The medical records and the final pathologic reports of female patients were reviewed retrospectively. The follow up cut off date of this study was January 2008. We used Pearson's correlation to determine the association of pairs of explanatory variables and differences in qualitative variables were evaluated by Chi-squared test. Results : Among 596 women with a diagnosis of breast carcinoma since 2002, 17 women were diagnosed of developed differentiated thyroid carcinoma after the diagnosis of breast carcinoma. The mean age at the diagnosis of thyroid cancer was 49 years. 17 patients who had thyroid carcinoma were defined as Group-1 and the remaining 579 patients were defined as Group-2. There was no distributional difference of adverse prognostic factors between two groups. There was a death in two patients of Group-1 and nine patients of Group-2. Therefore, the rates of 5-year overall survival rate were 88% in Group-1 and 98% in Group-2. Conclusion : Adjuvant radiation therapy after breast opearation due to breast carcinoma didn't influence on the occurrence of thyroid cancer. And our study indicates that the occurrence of breast cancer followed thyroid cancer didn't influence the 5-year overall survival rate. But our study has some limitations such as retrospective study and relatively short follow-up period.

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.

Many investigators have focused on the socialization of attitudes and values across generations in the family. Generational transmission is the process through which attitudes, values and expectations associated with the learning and performance of roles are conveyed from one generation to another. A number of contradictions have been identified in the literature on generational transmission. Some of the studies have provided evidence of generational similarities, whereas other investigators have indicated that value differences exist between parents and children. In many studies of intergenerational differences it is found that the young are directed toward developing their own life style and attitudes abut major social issues, as opposed to validating existing values and strategies, whereas the parental generation committed to passing on the attitudes, values, and expectations associated with existing roles. In this process, they also have considerable capacities to restructure their social situations. Much of parent-child interaction, therefore, involves role-making, that is, the process of improvising, exploring, and judging what is appropriate on the basis of the situation. However, when society changes rapidly, both generations experience conflicts in their expectations and a confusion in the definition of situation. Moreover, the young adults, particularly college students in Korea, are expected to be independent in many aspects, but they are still dependent on their parents in various ways. This study is an attempt to investigate whether there exist the intergenerational similarities or differences between young adult children, particularly college students, and their parents in differences between young adult children, particularly college students, and their parents in Korea. In order to pursue this basic objective of the study, several different but interrelated dimensions were considered. (1) Consensus: the degree of similarities or differences in general values of family, views on marriage, and specific sociopolitical opinions, (2) association: the frequency of interaction and type or nature of companionate activities shared between parents and children, (3) affect: the negative or positive sentiment, the feelings and perceptions of closeness or distance, and the feelings of trust, (4) exchange of assistance and support between parents and children, and (5) norms and ideal images of parent-child relationship and the perceptions of what should be done between parents and children, reflecting duties and responsibilities. The data set used in the study was drawn from a small sample survey conducted by the authors in November 1990. In order to see a more precise parent-child relations the study conducted parent-child comparisons within the same family, in addition to comparing across entire cohorts of parents and children. The subjects were consisted of 194 pars of college students and their parents. All of the child-respondents were women and 46 cases were fathers among parent-respondents. A total of 388 cases were collected and analyzed. The findings suggest the followings: (1) There was a high degree of similarities rather than differences between parents and children in general values on family and sociopolitical opinions. (2) Although attitudes of parents were slightly more traditional than childrens, both generations showed relatively high degree of modernity in general values on family and marriage, and most of social issues. (3) The young tended to be individualistic and shrewed in heir general values, while parental generation emphasized collectivity and authority. (4) There was a rather big gap between parents and children in their attitudes about students demonstration. Whereas almost all parents had strong negative attitudes, almost a half of the childrens response showed somewhat positive attitudes. (5) We have seen that children had relatively frequent contacts and interactions with parents and that they shared such activities as dining together, watching T.V. and dialogue. Children also tended to have more frequent contact with mothers than with fathers. (6) The nature of communication showed that there existed basic rust and closeness between parents and children. (7) College students were primarily dependent recipients of parental support not only economically but in various ways. Nevertheless, they had little contribution to family affairs as a member. Moreover, they were not autonomous in various decision-making processes, and the degree of perceiving themselves as being independent was much lower than their parents. This result may be partly related to the over-protection by parents due to the extended period of education for college students and the college entrance examinations.

이동수,염석원,손정영,김신환 대구대학교 정보통신연구소 2010 情報通信硏究 Vol.7 No.1

본 논문은 수동형 밀리미터파 영상 시스템을 이용하여 은닉된 물체의 영역을 검출에 관한 연구이다. 밀리미터파 영상은 악천후에도 영상 촬영이 가능하고 플라스틱, 종이, 나무, 옷, 머리카락 같은 특유한 물질들을 투과한다. 그리고 밀리미터파는 금속과 특수한 인공 구조물에 대한 반사율이 높기 때문에 은닉된 물체를 쉽게 검출할 수 있다. 본 논문에서는 밀리미터파 영상에서 은닉된 물체 검출의 영상 분할을 자동 문턱치 방법으로 나타낸다. 본 논문에서는 8㎜ 파장을 수평과 수직 편광 방향으로 수신하는 두 채널에서 획득된 밀리미터파 영상을 Gonzalez와 Otsu 방법으로 영역 분할을 한다. 실험 결과는 Gonzalez과 Otsu 방법 모두 은닉된 물체 영역의 형태를 잘 분리하지만 Otsu 방법이 노이즈와 몸체 영역의 경계 부분이 안정적으로 영역 분할됨을 보인다. We address an image segmentation method to detect concealed objects captured by passive millimeter wave (MMW) imaging. Passive MMW imaging can create interpretable imagery on the objects concealed under clothing. Due to the penetrating property of the MMW imaging, the MMW imaging system is often employed for the security and defense system. In this paper, we develop automatic thresholding methods for the segmentation of concealed objects detected by PMMW imaging. The automatic thresholding method is useful for the image with bimodal distributions. We compare several thresholding methods for two MMW channel images which have 8 mm-horizontal and 8 mm-vertical polarization, respectively. The experimental results show that concealed weapon area is well segmented from the background body by the presented methods.
