최근 위성영상이 도시계획 및 관리에 필요한 정보를 획득하는 수단으로 큰 각광을 받고 있지만 도시계획 분야에서는 위성영상이 현황을 설명하는 보조 자료나 지도를 대신하는 베이스맵으로만 이용되고 있는 실정이다. 본 연구는 도시정비사업의 정비예정구역 지정을 위해 사용되는 각종 지표를 표현할 수 있는 세부측정항목을 추출해 내고, 이렇게 설정된 세부지표 측정을 위해 위성영상과 GIS를 활용하였다. 위성영상과 GIS를 연계하면, 도시정비사업의 정비예정구역 지정을 위한 각종 지표들을 정량적으로 파악 할 수 있을 뿐만 아니라 정비예정구역의 지표특성을 기초로 하여 정비유형을 결정하는데 기여 할 수 있을 것이다. Recently, the satellite image is getting large spotlight as a way for getting necessary information of urban planning and management, but the satellite image is only used to explain the status or basemap instead of paper map in urban planning works. From this study we derived the detail indexes to fix the boundary of urban improvement project, for measuring these indexes used with satellite image and GIS. the linkage of GIS and satellite image let us to catch the indexes and contribute to improvement type deciding in Urban Improvement Project.

Growth-oriented urban master plan has been established up to now but it is time to prepare low population growth because our country has reached a plateau after the rapid growth period. Therefore, this study intends to classify type of cities by reflecting change in circumstances such as low birthrate, aging and increase in single household and then, to find out establishment measure of urban master plan and political considerations as per the type. First, as for a growth type, it is all right to set up an urban master plan according to the one suggested in the guidelines for urban master planning but it is required to have planned management on the outskirts of a city to prevent extension and thoughtless development. Second, as for a low growth and stagnant type, it is most important to set up planned population through forecast of natural increase and social increase and then, it is required to establish a landuse plan. In addition, it is required to have city management through growth control to prevent thoughtless development and to do planned administration. Third, as for a decreasing type, it is required to have a compact type urban plan and to control the area without development through alteration of use district.

The purpose of this study is to quantitatively evaluate the project performance of the urban regeneration leading areas selected in 2014. In the case of urban regeneration projects, although qualitative evaluation of the satisfaction felt by the residents in the areas is important, objective and quantitative evaluation of the project performance is also important. Therefore, this study aimed to quantitatively evaluate project performance by comparing objective data at the time of project selection (before selection) of the urban regeneration leading areas with those at the time when the projects were completed. This study verified the performance between before and after the projects using decline indicators such as population, the number of businesses, and the number of employees based on the census output area space units of 13 leading areas designated in 2014. Populations and the numbers of businesses decreased by 6 ~ 70% of the 13 regions, but the numbers of workers increased in the majority of the areas. As such, diverse indicators to measure project performance through big data analysis according to the objectives of projects should be developed and methods to use the indicators should be presented.

Credit rating represent an assessment of the relative level of risk associated with the timely payments required by the debt obligations. Credit rating is essential for the capital market to works efficiently. The results of credit rating by a professional agency are major criteria to banks` decision of loans and their terms. There are three domestic credit rating agencies. They use judgmental methodology rather than scientific and quantitative tools. In the period of economic liberalization, more attention is paid to the development of scientific credit rating system. The traditional techniques for creidit rating are statistical models such as MDA, probit, and logit. Artificial intelligence techniques such as inductive learning and neural network have been applied for credit rating since late 1980`s. In this research, we developed NICE-AI, which is the first credit rating system based on the neural network models. NICE-AI is available in the commercial information service, NICE-TIPS by National Information & Credit Evaluation In.

이상재(Sang Jae Lee),한인구(In Goo Han) 한국경영학회 1998 經營學硏究 Vol.27 No.2

In this paper, the decision support system for auditing the EDI system is developed. This system is based on the database system which has entities - control, risk, company, test, etc. E-R(Entity-Relationship) diagram and DFD(Data Flow Diagram) are drawn for logical system design. FoxPro, database package, is used as a development tool. An auditor can retrieve and store test results by using this system. An auditor can suggest required controls through cross-reference between control, risk, company, test result tables. Different controls, risks, and test checklists can be stored for different companies. This system can improve the efficiency and effectiveness of EDI auditing and can be applied to general EDP auditing.

According to knowledge-based view, knowledge is an essential strategic resource for a firm to retain sustainable competitive advantage. As knowledge is created and disseminated throughout the firm, the firm can enhance its capability to respond to new and unusual situations. Thus, a lot of companies actively manage their knowledge and intellectual capital. Especially, knowledge management (KM) activities in R&D organizations play a critical role in enhancing R&D performances such as innovation capability. In this regard, this study develops a theoretical model to examine the effects of R&D KM activities on R&D performance. The research model posits KM participation, knowledge management system (KMS) use, and community of practice (CoP) as the main activities of R&D KM. This study proposes that R&D shared knowledge quality and R&D KM satisfaction play a mediating role between R&D KM activities and its performance. The proposed research model was tested by using survey data collected from 248 employees in an R&D department. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that R&D KM activities play a significant role in enhancing R&D performance. The findings revealed that R&D shared knowledge quality is not significantly related to R&D performance, while R&D KM satisfaction significantly influences R&D performance. The theoretical and practical implications of the findings were described.

Credit rating for commercial loans is an important task for loan officers of a bank who usually use a credit-rating teble(CRT) based on a point system. However, the loan decision making using such a table has its limitations as follows. First, CRT needs a few critical judgments for commercial loans. For example, the judgments consist of knowledge.acwuisition on the criteria such as variable selection, weights between variables. cut-offs between intercals within each variable, and relative value at each interval of the variables for caredit rating. The first level criteria such as quantitative and qualitative variables need to be expressed on interval scales to assess a credit score for each variable. However, the variables present a problem in terms of measutability. This problem renders it impractical to directly applly theretical or human expertise-based choice strategies to unstructured choice problems. The objective of this study is to presesnt an optimal knowledge acquisition and refinement method of the CRT using genetic algorithms(GAs). In our proposed model, the GAs search the optimal criteria for the CRT applied to credit rating process. For the purpose, the CRT and the GAs are integrated to extract and refine the knowledge of multi-criteria for the CRT. The obtained knowledge supports to find optimal parameters of the CRT for loan officers` decision making. Our experimental results show that the knowledge acquisition and refinement method using the GAs are effective for the CRT as a multi-attribute decision problem.

Given the large investment and prevalence of knowledge management (KM) in organizations, it has become important to analyze the effects of KM activities on organizational performances. A theoretical framework is proposed to investigate the impact of KM activities on innovation capabilities in the IT service industry. This study considers KM activities as the major determinant that enhances absorptive capacity. KM activities enhance employees` ability to obtain external knowledge, resulting in increasing intellectual capital. Thus, this study proposes that absorptive capacity plays a mediating role between KM activities and innovation capability. Additionally, this study investigates the key antecedents of KM activities that promote employees` knowledge sharing. Based on prior studies on KM, this study posits KM team activities and top manager support as KM activities. The proposed research model was tested by using survey data collected from 556 employees in the IT service industry. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that KM activities and absorptive capabilities play a significant role in enhancing service innovation and process innovation in the IT service industry. The results also shed light on the mediating role of absorptive capacity between KM activities and innovation capability. Moreover, both KM team activities and top manager support serve as the salient antecedents of promoting employees` knowledge sharing.

Objectives: The purpose of this study was to investigate influencing factors on physician`s intention to use cyber salesperson(cSP) to promote ethical drugs of pharmaceutical company. We considered influencing factors based on technology acceptance model(TAM) such as usefulness, easy of use, and attitude about cSP, and included trust and joyfulness of cSP. Methods: Measure items were developed from the previous studies. Data were collected from 1,012 physicians by using web-based self-administered structured questionnaire. Results: The major findings were as follows; First, attitude and intention to use cSP were not significantly varied by socio-demographic variables, such as sex, age, location, and Internet surfing time per day. Also, physician`s characteristics such as training and professional level and type of employment were not significant to the variation of attitude and intention to use cSP. Second, structural equation modeling(SEM) analysis shows that usefulness and joyfulness were influencing factors of intention to use. Attitude was revealed as significant mediating factor to intention to use. Usefulness has indirect effect on intention to use via attitude. However, trust has not significant effect on intention to use, due to suppression effect. Conclusions: This results implies that cSP will be a useful agent to promote the ethical drugs to physician. Usefulness and joyfulness should be considered as important factors in designing and operating cSP in the Internet.
