An enterprise resource planning (ERP) system is an enterprise wide management system made possible by information technology. Organizations have been implementing ERP packages for integrating the business process in various functions. ERP has been helping companies to automate their entire business processes within the organization as a whole instead of just in some functional units. This paper presents five case studies indicating that enterprise resource planning (ERP) systems do enhance the performance of manufacturing organizations. The ERP systems studied are from SAP, Baan, and Oracle. In all five cases, better cross-functional integration was a critical success factor.

In tall building construction, lift car for worker lifting is a critical factor for construction productivity. To reduce worker lifting time, existing researches have been conducted on lift car planning. While, research on lift car operation is insufficient. For the efficient reduction of worker lifting time, lift car operation control is needed with lift car planning. Therefore, this research suggests operation control model of lift car to reduce worker lifting time. According to the result of a model test, the operation control model contributes to reasonable reduction of worker lifting time.

This research suggest a causal model to investigate factors and variables which significant effects on user satisfaction with city park recreational facilities in Duryu city park in Taegu, and thereby identifying implications for planning and development of urban parks and open space. For this study the data were gathered by self-adminstered questionnares from 993 households selected by the multi-stage probability sampling method. The analysis of the data consists of two phases. The first involves exploratory factor analysis to draw meaningful factors from the data. Three factors were indentified. The second phase test the causal model of this research employing LISREL methodology. On the base of the analysis results, important implications for planning of city park and open space are recommended.

Green and plants, as it symbol the life and depute the nature, always give human an easy comfort psychologically. The paper is a brief analysis to the idea frame of urban construction and reform of Kunming through our practice about ten years. On which three main principles should be carefully considered. One is that the green-space composed of plant system is of the important infrastructure of a modern city as it can not be instead of by any other factor in the ecological system of the city. The other is that in the course of planning and construction the local feature as well as its culture tradition in history should be pied more attention. In order to create a distinguish character of itself the third may be more important that to coordinate each key elements of it such as green, water, light, building, road, etc., to get a harmonious sphere of human and nature. A modern city should be a green city in which nature and man co-exist harmoniously.

Enterprise Resource Planning(ERP) systems offer pervasive business functionality the applications encompass virtually all aspects of the business. Understanding and managing this pervasiveness will result in a successful and productive business application platform. Because of this pervasiveness, implementations have ranged from great successes to complete failures. This article has two distinctive parts. The first proposes and discusses a systematic process based on consulting experiences of LG CNS (leading information system company in Korea) for ERP selection. Also, the second provides the key factors that are critical to the successful implementation of ERP. The second part reports the results of a study carried out to assess a number of different ERP implementations in different organizations. A case study method of investigation was used, and the experiences of five Korean manufacturing companies were documented. The critical factors in the adoption of ERP are identified as: learning from the experiences of others, appointment of a process innovator, establishment of committees and project teams, training and technical support for the users, and appropriate changes to the organizational structure and managerial responsibilities.

In this study, the writer embodies factors influencing on ship safety management by an empirical survey. In the empirical survey, the writer used a questionnaire. 1, 271 proper data was obtained from 4, 240 Korean seamen working in 152 domestic and 60 foreign merchant ships. Reliability was tested by Cronbach's Alpha and a conceptual validity by Factor Analysis. Hypotheses established in this study were tested by Correlation and Multiple Regression Analysis. Results of analysis are as follows: Firstly, three levels(i.e. planning, doing, and evaluation) of safety management and satisfaction level of shipboard life correlate significantly with level of ship safety management and between them(P<0.05) Secondly, satisfaction level of shipboard life, evaluation and planning levels of safety management influence significantly on level of ship safety management(P<0.05).

Today, as the power trades between generation companies and power customer are liberalized, the uncertainty level of operated power system is rapidly increased. Therefore, transmission operators as decision makers for transmission expansion are required to establish a deliberate investment plan for effective operations of transmission facilities considering forecasted conditions of power system. This paper proposes the methodology for the optimal solution of transmission expansion in deregulated power system. The paper obtains the expected value of transmission congestion cost for various scenarios by using occurrence probability. In addition, the paper assumes that increasing rates of loads are the probability distribution and indicates the location of expanded transmission line, the time for transmission expansion with the minimum cost for the future by performing the Montecarlo simulation. To minimize the investment risk as the variance of the congestion cost, Mean-Variance Markowitz portfolio theory is applied to the optimization model by the penalty factor of the variance. By the case study, the optimal solution for transmission expansion plan considering the feature of market participants is obtained.

This survey was performed with 262 dwellers who live in the city from April 1 to 30, 2009. The following analysis methods were executed; frequency analysis, reliability analysis, factor analysis, and multiple regression analysis. This study analyzed the relationship between rural tourism motivation and rural experiential tourism program preference of city dwellers. Rural tourism motivations are novelty experience, advantageousness, self-attainment, aesthetics, deviation, relationship, relaxation, and nature-scenery. And rural experiences are divided into farmhouse life experience, traditional rural culture experience, outdoor activities experience, wellbeing healthcare experience. Authors found that rural tourism motivations affect rural experiential tourism program preference. So, authors argue that rural tourism needs market segmentation strategy.

The purpose of this study was to identify factors related to residential satisfaction, and to examine the rural housing and village environment which enable to derive what should be considered in the future rural housing improvement. Data were collected by questionnaire survey in 11 rural villages - suburban rural area, plain rural area, intermediate rural area, mountainous rural area. The major findings are as follows: 1) The rural residents rather dissatisfied with'management/maintenance','economic value','facade'in housing level, The overall housing satisfaction level was just medium(neither satisfied nordissatisfied). 2) They also dissatisfied with'playground for children','education condition','medical facilities', 'market'in village level. The overa'll village satisfaction level was just above average(slightly satisfied). 3) Vrom the result of ANOVA test, there are no significant differences in residents evaluation for tiousing and village attributes among 4 rural areas. 4) Factor analysis identified six rural housing environmental factors:'inside utilities','housing size' 'aesthetic aspects','safety','privacy','outside utilities'. 5) For the rural village environments six important factors were derived :'public services','commercial convenience facilities','social interaction','environmental pollution','amenity','agricultural service facilities'.
