We suggest how to search news data by dividing structurely, by classifying meaningly, and by itemizing them by contents. The structural division divides the scene using correlative information between frames such as the distribution of the space brightness and the irregularity of brightness, and time relation etc. The meaning classification means to classify the detailed contents of news video as articles comparing special information extracted frame key frame with previous knowledge information. This study classifies the articles as the anchor's scene and the non-anchor's scene using the character that the progress of news is repeated centering around the anchor frames by periods. We get the non-anchor's scene to search the news data itemizing speech scene, interview scene and general scene, and classifying as articles. Also, we use the function of searching for summary by news icons and search the caption by processing the integration of caption, and design them to be able to search the news video quickly classifying news video as contents and indexing them.

A numerical procedure for the analysis of transient behavior of a monolithic catalytic converter is presented. The thermal behavior of a monolithic catalytic converter is fully coupled with mass transfer and exothermic reaction between exhaust gases and the catalytic converter. In the present study, all these processes are solved simultaneously. The heat transfer process is also simply modelled by using combinging one dimensional convention and conduction and the chemical reaction is also simply modelled by using the concepts of reaction rate and reaction heat. All the partial differential equations for the heat transfer, mass transfer and chemical reactions are approximated by using finite volume method. Resulting algebraic equations are solved using the Newton's method. To see the workability of present numerical method, two well known problems, step increase and step decrease in the gas inlet temperature, have been calculated. Present numerical method shows a good convergence behavior for two test cases : converged solution were obtained with 8 iteration (for tolerance of ??)at most through out the whole calculation domain of space and time. Comparison of present solutions with previous solutions shows a good agreement.

Objective : To compare two different methods of rigid fixation in postoperative stability after mandibular setback, Material and Methods : 28 patients with Class III malocclusion were treated by bilateral sagittal split ramus osteotomy(BSSRO) and mandibular setback were selected for this study. Group A(n=14) had the bone segments fixed with monocortical miniplate on the lateral side of the mandibular body and Group B(n=14) had three noncompressive bicortical screw inserted at the genial area through a transcutaneous approach. Cephalograms were taken preoperatively, postoperatively within 1 weeks and at a follow-up period (mean 8.9 months after surgery) and the amount of setback and postoperative change were measured. Results : Postoperative relapse between two groups was minimal in setback of the mandible. Statistical analysis showed no significant difference in postoperative relapse. Conclusion : This study suggests that both methods of skeletal fixation investigated give comparable postoperative stability and their use in mandibular setback appears to be a fairly stable clinical procedure.

Background : Aim of this study is focused on the analysis of the needed abilities of medical representatives resulting in building up the market and increasing sales. It is to propose methods to increase this ability ensuring continuous growth in market share and profit. Methods : A survey was conducted between January 6 and May 31, 2003. Using SPSS(Version 10.0), the collected data was analyzed by Hotelling T2, factor analysis. Some hypotheses were selected to include the conclusion. Some questionnaires for physicians working in hospitals or clinics and the medical representatives working in a pharmaceutical company were created and asked to them to either prove or reject those hypotheses. The results were analyzed to find the primary factors that effect the interactions between physician and the medical representatives. These factors were also studied along with the theoretical research based on published references. Results : The results were as follows. The main reasons for the physician to meet with a medical representatives were collection of product informations needed for patient treatment and collection of informations on current medical issue and as well as personal interests. The main parameters by which physicians evaluate the medical representatives are human relationship including sincerity and manners and supply of accurate and unbiased information on products. Overall, the medical representatives’ perception on the importance of medical knowledge and ability to deliver it are lower than that expected by physicians. Conclusion : Medical and pharmaceutical companies’ environment are changed rapidly. And those changes forced medical representatives to set new roles and competency. In order to drive away from the past ‘rule of thumb’ and ‘adaptation to circumstance’, optimal method and systemic development to train and support the medical representatives should be quipped. They will help ,medical representatives to be specialists in medical knowledge and to understand the exact need of health care professions. Product competitiveness will be increased and eventually successful business can be achieved through it.

This is the second part of our study concerning reorganization of Industry locations in Incheon city The aim of this study is to extrapolate the spatial influence of the five leading categories of manufacturing and the related industries In connection with spatial distribution. Using regression equation based on Gravity Model, we tried to estimate Spatial Influence Index of leading categories, the result of which was analyzed to deduct the systematization tendency of the leading categories and their distribution in Incheon city. The Implications of the result to the policy-making can be summarized as follows 1) Designation of a certain industrial area as a target of relocation can possibly result in the weakening of the leading categories of manufacturing industries by letting them to lose their competitiveness Accordingly, the policy-making should be guided by careful consideration on the characteristics of industries examined by types and regions 2) Considering the fact that the four leading categories have reached a certain degree of formation of interrelationship among themselves, It is recommended to reorganize the industrial location m the course of strengthening the possibility of mutual influence with the rest of the related industries 3) If industries excluded from the leading categories are proved to be highly interrelated with them, the integration of such industries with the leading categories should be taken into consideration in the policy-making of the industrial reorganization

김동배,김강식 한국항공대학교 경영연구소 2000 경영연구 Vol.7 No.2

본 연구는 인사관리와 조직성과에 대한 선행연구들을 비판적으로 검토하고 있다. 인사관리는 어떻게 조직성과를 높이는가, 조직성과를 높이는 인사관리가 왜 확산이 느린가가 주요한 검토 대상이다. 인사 관리가 조직성과에 미치는 영향경로는 크게 구조적 효과, 개인의 동기와 역량을 형성하는 개인행위를 통한 효과, 그리고 인사관리시스템은 조직의 전략적 자산으로서 지속적 성과를 낳는다는 3가지점을 검토하였다. 그리고 이와 관련해서 선행연구들에서 소홀히 취급하고 있는 4가지 점으로서 비용의 고려, 인사관리의 기능적 등가, 근로자 복지에 미치는 영향, 외부효과의 고려가 향후 연구에서 규명되어야 한다는 점을 지적하였다. 조직성과를 높이는 인사관리의 확산을 저해하는 요인들을 보완성의 문제, 변화 비용, 경영자의 인식과 행위, 그리고 사회제도의 4가지로 나누어서 검토하였다. 그리고 기존의 연구에서 소홀히 취급된 영역으로서 상이한 제도적 환경속에서 인사관리의 확산도 달라질 것이라는 점을 지적하였다. This study examines the relationship between HRM and firm performance. Especially this study reviewed how HRM enhance firm performance, and if HRM enhance firm performance, then why such HRM does not diffuse rapidly? With the first question, we examined 3 mechanism that is through structural effect, individual motivation and capability, and as a strategic asset HFZM system create sustained competitive advantage. In addition we pointed out that cost of HRM adoption, functional-equivalent of HRM, employee welfare, and external effect of HRM practices should be incorporated in future studies. As barriers of HRM diffusion, we examined complementarities of HRM practices, switching cost, managers belief and myopic behavior, and institutional factors such as corporate governance, industrial relations system, and national education and training system. In addition we pointed out that HRM diffusion will show difference by countries because institutions are differ by countries. So institutional difference should be considered in future studies.

In general, the viscosity of fluid increases as temperature decreases, and decreases as temperature increases. This phenomenon can be explained by decreasing mobility of molecules as temperature decreases. But, we found the opposite phenomenon that viscosity decreases as temperature decreases in particular mixed surfactant system. To analyze this phenomenon, various experiments have been proceeded such as composition (anionic, nonionic, zwitterionic surfactant), variation of zwitterion surfactants, structure of hydrophobic chains, structure of Hydrotrope, variation of pH. Conclusively, controlling the complex of zwitterion and anionic surfactant, we could control the viscosity of mixed surfactant system on variation of temperature. We analyzed this phenomenon theoretically, and then can complete "The technology of viscosity control by temperatre in micellar phase".

In order to investigate the hypothetic defense mechanism of essential metals which take part in the healing process of bone fracture, the author measured the changes of whole blood concentration of Ca, Mg, Zn and Cu from 88 fractured patients as experimental group, and 49 healthy, male medical students as control group, using Inductively Coupled Plasma Emission Spectrometer. The obtained results were as follows. 1. The mean concentrations of Ca at the time of fracture, at 1 month after fracture and at 3 months after fracture were 52.55± 17.37 g/ml, 60.45± 14.37 g/ml and 65.33± 16.73 g/ml, respectively and increased significantly through the healing process of bone fracture(p<0.05). The Ca concentration of fracture group at 3 months was higher than that of control. 2. The mean concentrations of Mg at the time of fracture, at 1 month and at 3 months were 26.50± 6.76 g/ml, 28.46± 6.11 g/me, 29.51± 4.32 g/ml, respectively and increased significantly through the healing process(p<0.05). The concentrations of Mg in fracture group were lower than that of control(p<0.05). 3. The mean concentrations of Zn at the time of fracture, at 1 month and at 3 months were 6.73± 1.68 g/ml, 6.48± 1.25 g/ml, 6.91± 1.58 g/ml, respectively and the changing tendencies were not statistically significant through the healing process (p>0.05). The concentrations of Zn in fracture group were lower than that of control. 4. The mean concentrations of Cu at the time of fracture, at 1 month and at 3 months were 1.04± 0.38 g/ml, 1.11± 0.46 g/ml, 1.13± 0.42 g/ml, respectively and increased through the healing process, but the changes were not statistically significant (p>0.05). The concentrations of Cu in fracture group were higher than that of control(p<0.05). 5. There were positive correlations between Ca and Mg, Zn and Cu concentrations (p<0.01) in both fracture and control groups, but no constant correlations were found in the other metals. 6. The ratio of Mg/Ca was tend to decrease through the healing process of bone fracture, but the ratio of Zn/Cu was showed no constant change in fracture group and that was higher in control(p<0.05) 7. As above results, the changes of 4 essential metal( Ca, Mg, Zn, Cu) concentrations in whole blood have meaningful role in the healing process of bone fracture.
