  • Currently, Gyeongnam province is executing the social index survey every year to the provincials. But, this survey has the limit of the analysis as execution of the different survey per 3 year cycles. The solution of this problem is data fusion. Data fusion is the process of combining multiple data in order to provide information of tactical value to the user. But, data fusion doesn#t mean the ultimate result. Therefore, efficient analysis for the data fusion is also important. In this study, we present data fusion method of statistical survey data. Also, we suggest application methodology of association rule mining by clustering through data fusion of statistical survey data.

  • PURPOSES: The purpose of this study is to develop a methodology to prioritize sidewalk construction on rural national highways. METHODS : In order to determine an appropriate prioritization for sidewalk construction, we developed a specific methodology. The proposed methodology includes three main steps: 1) Analytic Hierarchy Process (AHP) methods, 2) Subjective evaluation of relevant road agencies for the candidate sidewalks along rural national highways, and 3) Field study conduction. Each step has four phases. The primary feature of this methodology is the addition of expert consultation and survey data, as well as a field study. In addition, the method could guarantee flexibility in selection for evaluation criteria. As a result, the proposed methodology could be used as a general procedure for application to other roadway classifications when considering sidewalk construction. RESULTS: In order to demonstrate the reasonableness of the proposed methodology, a case study was performed for exactly 100 candidate sites for sidewalk construction on rural national highways. All required evaluation scores were properly produced for each candidate site. By doing so, decision-makers can determine the priority for sidewalk construction at these sites by reviewing quantitatively and qualitatively considered data. CONCLUSIONS: The results of the case study can be applied to a long-term fundamental plan for sidewalk construction on rural national highways. Furthermore, this methodology could be employed to prioritize a small-scale SOC project(e. g. bicycle or pedestrian roads).

  • Irrigation canal systems were evaluated based on documentations and field survey. Field survey was conducted for main canals using GPS, with respect to canal characteristics such as canal material, presence of weed, potential inflow of sediment, sedimentation, and so forth. Methodology described in this paper could be used for planning maintenance practices.

  • The purpose of this study was to identify the characteristics of housing product through housebuilders' strategies. As a methodology for this study, literature survey and questionnaire survey were used. Questionnaires were delivered on mail to 232 housing-builders and return rate was 34.1%. In summary, housing product was characterized long gestation period, periodically building cycle, future uncertainty of market volatility, maximization of land development gain, utilization of public fund for continuous building activity, moral hazard by accidental bankruptcy. Therefore private housebuilding could be defined speculative industry.

  • The main purpose of this paper is to design a simple interactive software system for planning activities, called APS. We discuss the importance of informal and formal specifications of the system design, and survey a number of promissing design methodologies. To design APS, we present a methodology based upon the hierarchical decomposition of the system, and illustrate the methodology as applied to the design of an activity planning system.

  • In this study, an overall survey of ERP system and methodology are first introduced, then an efficient way of const겨cting ERP system is suggested through a case study on S company S company has not reached the goal of ERP system as it planned and is still working on the project. The main idea for the efficient construction methodology of ERP system is that BPR (Business Process Reengineering) should be accomplished and the company should have enough time to test the ERP package and a proper ERP team organization before the ERP system is introduced. It is suggested that introduction of ERP system bring about benefits to companies in terms of effective management system.

  • The purpose of this study is to assess and develop effective MIS planning method by applying the CSF method. With the comparative analysis of the Rockart's basic concept of CSF and the examples of the corporations which employed CSF methodology, a new CSF method more suitable to Korean business environment is proposed and applied to another company for evaluation. The new CSF methodology consists of three steps. The first step is to preexamine the business conditions. The second step contains an Introductory Workshop, interview with the managers, survey questionnaire, Focusing Workshop, and decision of the priorities for system development. The third step is a real development of an information system out of the first and second steps. As a result of this study, it is found that revised CSF method can induce top management to participate more in the activities of information system development and that it can make top management to focus on the critical area. The fulfillment of the information requirement out of the enhanced MIS planning will lead to more successful management activities.

  • We examine the response patterns to web survey with a series of experiments embedded in a survey of students at the Sookmyung Women's University. A sample of 960 students was sent e-mail invitation to participate in a internet survey, The response rate was 53.9% except partial and overall non-response. Methodological experiments included the use of a pre-notification, reminder notices as well as the type of questionnaire. These factors that manipulate the perceived burden of the task had an effect on the likelihood of accepting the survey invitation. This paper discusses the overall implementation and outcome of the survey, and describes the results of the imbedded design experiments. Also we compared the representative of self-selected and probability sample.

  • Purpose - The purpose of this study was to investigate consistency in estimating the number of vacant jobs using the two business labor force survey with two different time points of survey. Design/methodology/approach - We studied the cause of the differences in estimating the number of vacant jobs between the monthly sample and the new sample in business labor force survey. Findings - To summarize our findings, As the size of the company increases, the number of vacant jobs in the company also increases, and the probability that the number of vacant jobs in the company is zero decreases. The monthly sample was assessed to have a higher likelihood that the number of vacant jobs in the company was zero and the number of vacant jobs was considerable compared to the local sample. Research implications or Originality - Because local survey sample companies tend to minimize the number of vacant jobs even when they reply under the same conditions, the estimation result of the number of vacant jobs in the current monthly survey differs significantly from the estimation result of the local survey. Divergent "degrees of knowledge of question items," survey methodologies, or investigators could be the causes of the various response trends.

  • Purpose - This paper proposes measurement models to evaluate the management performance of small and medium-sized retail businesses on the basis of a trading area analysis that compares their proposed revenue to actual revenue in the trading area. Research design, data, methodology - The study proposes measurement models consisting of five stages, namely: (1) district background survey, (2) customer survey, (3) competitor survey, (4) business district survey, and (5) business performance analysis. Results - To identify business districts easily, this study preferred a minor-adjusted method based on the Euclidean distance, as it is simple to employ for the small and medium-sized businesses. This model was applied to select coffee shops in Daejeon. Results indicated that although the targeted shop was not located in an appropriate location, actual sales were higher than expected. Conclusions - Small- or medium-sized retail businesses face difficulties regarding the economies of scale and brand recognition and must choose an appropriate location to ensure management stability. However, such businesses will find it difficult to evaluate their competitive edge accurately using a trading area analysis.
