This paper considers an assembly-type flowshop scheduling problem in which each job is assembled with two types of components. One type of the components is outsourced with positive lead time but the other type is fabricated in-house at the first stage. The two types of the components should be prepared at the first stage before starting the assembly operation for each job at the second stage. The objective is to schedule the jobs so that the makespan is minimized. Some solution properties and lower bounds are derived and incorporated into a branch and bound algorithm. Also, an efficient heuristic is developed. The performances of the proposed branch and bound algorithm and heuristic are evaluated through computational experiments.

The characteristic features of Malaysia's climate is has stable temperature, with high humidity and copious rainfall. Weather forecasting is an important task in Malaysia as it could affetcs man irrespective of mans job, lifestyle and activities especially in the agriculture. In Malaysia, numerical method is the common used method to forecast weather which involves a complex of mathematical computing. The models used in forecasting are supplied by other counties such as Europe and Japan. The goal of this project is to forecast weather using another technology known as artificial neural network. This system is capable to learn the pattern of rainfall in order to produce a precise forecasting result. The supervised learning technique is used in the loaming process.

With the explosive proliferation of smart devices that may be connected to the fast Internet, virtual desktop interfaces(VDI) are being implemented in enterprises allowing employees to work anywhere anytime in the same technological environment. As this kind of systems are intended to raise the work performance, a research model is constructed from the review of research literature on service quality and work design. The model consists of VDI system service quality (ubiquity, availability, compatibility, security and ease of use), system satisfaction, task performance and job satisfaction. As VDI is designed as a support system for cooperative work, the task interdependence adopted from the work design theory is postulated here as moderating the effect of user satisfaction on task performance and job satisfaction. 147 data points were collected by a survey of VDI users in a global firm and subjected to PLS analysis. Interestingly, ubiquity and compatibility seem to be not statistically significant for user satisfaction while availability, security and ease of use of VDI system are statistically significant. Task interdependence is found to be a relatively strong mediator between system user satisfaction and task performance, however, interestingly, the coefficient come out as negative. This may indicate that the influence of VDI user satisfaction on task performance would not be high in highly interdependent tasks. Considering that VDI is intended for supporting 'interdependence' in cooperative work, this finding is a bit surprising. In-depth discussions are made in the discussion followed by future research directions.

While the recent advance in network system has made it easier to collect and process personal information, the loss of customers, financial companies and even nations is getting bigger due to the leakage of personal information. Therefore, it is required to take a measure to prevent additional damage from the illegal use of leakaged personal information. Currently, financial companies use access control in accordance with job title or position on general documents as well as important documents including personal information. Therefore, even if a documents is confidential, it is possible for a person of the same job title or position to access the document properly. This paper propose setting up security grade of documents to improve current access control system. It will help preventing the leakage of personal information.

The purpose of this study was to explore the labor relations and job attitudes on KORAIL's employees. The subject of the study was the members of the Gyeongbuk Headquarters of Korea Railroad Corporation(KORAIL). For the purpose of analysis, a survey was conducted for 155 members of KORAIL Gyeongbuk Headquarters, and 119 questionnaires were used for the final analysis. The results of the analysis are as follows: First, there are 3 powerful parties in the KORAIL system of labor relations as Union, Management and Goverment. The KORAIL system of labor relations is very unstable and rigid. The labor union of KORAIL engaged in a desperate struggle against the management. Second, there are significant differences in job satisfaction, communication, organizational commitment, job attitudes between union members and non-union members. These results indicate that establish a labor-management community culture, communication need to be more activated. The activation of communication can contribute to building confidence in labor-management relationship.

In this paper, we propose Fuzzy M/M/1/K queueing network model which has derived by appling the fuzzy set theory to M/M/l/K queueing network model in which has single server and system capacity K. When the arriving rate of input job and the servicing rate of a server arc represented as the linguistic attributes, the system analysis can be performed by using this model. The major evaluation measures of system such as the average number of jobs existing in the system, the average number of jobs into system, and the average spending time of job in system etc. are derived for the evaluation of system. Computer simulation was performed for verifying the effectiveness of these result equations. In which the various fuzzy arriving rates and fuzzy servicing rates according to varying the system capacity K were given for the system evaluation. We verified that the results of simulation are in accord with the expected evaluations in the proposed fuzzy model.

The purpose of this study is to clarify the relationship between organizational characteristics and information systems characteristics or job satisfaction, attempts to examine the regulatory effects brought about by the adjustment of social capital theory. So far, The results of this study are based on the analysis of individual models from the perspectives of each functional organization such as HR, organization, finance, operation, and MIS. Therefore, this paper attempted a comprehensive analysis of factors affecting job satisfaction and firm performance by presenting an integrated research model of organizational perspectives in addition to the approach of MIS perspective. The characteristics of information system were promptness, CEO support, and compensation. And the organizational characteristics were multiple regression analysis using innovation, trust, and preferential factors. The analysis data is based on sixth data from the HCCP of Korea Productivity Center. According to the analysis results, all the variables had a significant influence on satisfaction, especially CEO support and trust. The analysis of the moderating effect between innovation and job satisfaction was moderated by vision sharing. Only the logistic regression analysis of the satisfaction with the average salary of the members among the demographic variables was statistically significant. Therefore, this study can be concluded that the overall satisfaction level will be improved by recognizing appropriate compensation as sufficient compensation.

In this essay, we hoped to see how the operational university job database systems perform badly, since there are a lot of signs that they fall short of data design fundamentals. Fortunately, we are able to choose a university employment support database(UESD) application as a candidate for our study. We have taken UESD system as it is and we have developed an enhanced version of the UESD system, which strictly followed the basic fundamentals in data modeling and named it as NewUESD system. Then, we have conducted a comparison to see how much UESD system is deviated from the standard balancedness found in NewUESD. From the perspective of data obesity, we computed how much UESD contains unnecessary data. The NewUESD contained no unnecessary data at all, which implies that it has only data that is necessary to form a data model. But the data obesity of UESD system is found to be more than 50%. Therefore, it is significantly higher, 37% higher in this case, than the obesity judged to be normal, which is 19% in NewUESD system.
