In the success of an IT project, the role of S/W developer in carrying out the project is critical and crucial. However, compared to its importance, there is only a few studies on the role of human resources in software engineering field, mainly focusing on technology. Based on regulatory focus theory, this study examines how the effect of technology recency on developer's intention to participate in the IT project changes depending on the regulatory focus of the software developer. As a result of the experiment, it was confirmed that there is a difference in the effect of technology recency on project participation intention according to the condition of developer's regulatory focus. This study is meaningful because it extends regulatory focus theory to software engineering field and made theoretical contribution to the research field of behavioral software engineering. In practical, it was possible to suggest a way to improve the intention of the developer to participate in the project, by understanding the software developer in the IT project, considering the software developer propensity and project characteristics.

An intelligent developer replenish system was developed for automatic film processor. The system detects the gray level of a developed film and determines the amount of the developer to be added to the system. Using the film darkness detection system, it was found that the film darkness is inversely proportional to the amount of light exposure, that the developer retrograde after developing certain number of films without replenishment and the number is dependent upon the parts of the body, and that the developer does not retrograde when 30 ml of developer is added after each chest film processing. The use of this system resulted in a decrease in the amount of developer by 40%.

Using an optical 3D scanning device to collect data from a diffused reflection surface is very difficult. To solve this problem, there are many applications including a spray-type developer and silicon molds. However, using a developer can cause chemical reactions between objects and particles of the developer and uneven surfaces on the object. To overcome these problems, we suggest an electrostatic powder coating method for even coating of particles onto surfaces for collecting 3D shape data. We have developed an automatic, electrostatic powder-coating machine and performed three different experiments to compare this system with a laser interferometer and a T-scan 3D scanner. As a result, we could ascertain the various characteristics of this new method, including good sensitivity for the various surface states of the bare surface, developer, and electrostatic powder coating. Finally, we verified the outstanding scanning performance and were able to demonstrate that this method achieves quality than traditional methods.

The objectives of this paper are to provide software developer selection criteria and to develop evaluation framework using AHP (Analytic Hierarchy Process). The selection criteria are extracted from Software Development Life Cycle, Quality Assurance, and Productivitiy of Organization. In this paper, the selection model is proposed and its examples are illustrated. Though some further research is required, the proposed model can be regarded as a basis of a DSS for the selection of the software developer.

Nowadays, many organizations more increasingly show their interests in developing informations systems through not only in-house development but outsourcing. Selecting a proper information system developer, however, is not easy task partly due to the absence of evaluation criteria pertinent to explain the pros and cons of information system developers considered. Further, much care should be taken of choosing an appropriate decision method applicable to semi-structured or strategical decision making problems such as selection of information system developer even though evaluation criteria are well provided. The purpose of this paper is to provide for the selection process, ranging from identification of problem structure to solution method, of information system developer with the use of Analytic Hierarchy Process(AHP).

The purpose of this study was to gain understanding about residential satisfaction and preference of the members of the future elderly generation who have an intention to develop senior congregate housing. The data for this study were collected from 600 participants who were in their 40s to 60s, residing in Seoul, and who have an intention to develop senior congregate housing. The data collection spanned from December 1st to 20th, 2004. The results of this study were as follows: Firstly, the respondents who had a higher level of education, higher income, and a high-ranking job showed relatively higher residential satisfaction with their present house. Similar satisfaction level came between their present house and expecting ones in their later life. Financial responsibility was the most serious expected problem when they continue living in the present house in the later life. It means that the economic ability is the primary factor that determines whether they will have a stable life later. Secondly, as for the preference for the senior housing developer type, the group who preferred collectively developed senior congregate housing far outnumbered the other who preferred independent developer type. Also, the group who preferred collective developer type had higher economic ability than that of the other. These results indicate that above all, economic competence is the must significant variable, which should be considered in the future life and residential planning for the elderly. Korean senior congregate housing models should be developed based upon elaborate research. It is also necessary to develop different types of housing, such as a more practical type and a high quality type, as well as to respond to different kinds of developmental objectives, such as marketability and public benefit.

The number of the enterprises which utilize network technology has been increasing for solving problems such as productivity improvement, market trend analysis, and material collection for making decision. Especially, the management of equipment and the recovery time reduction when machines break down are very important factors in productivity improvement of the enterprise. Currently, most of the remote trouble diagnosis of equipment using the internet have just one function of transmitting the trouble information to the user. Therefore it does not directly reflect the user's recovery experience or the developer's new recovery methods. If the user's experienced recovery methods or the developer's recovery methods as well as the basic recovery methods are reflected online or on the internet, it makes it possible to recover faster than before. In this paper, we develop a Remote Monitoring Server (RMS) for chip mounters, and make it possible to reduce the recovery time by reflecting the user's experience and developer's new methods in addition to presenting the basic recovery methods. For this, trouble recovery concept will be defined. Based on this, many functions(trouble diagnosis, the presentation of the basic recovery methods, user's and developer's recovery method, counting function of the trouble number of each code, and presentation of usage number of each recovery methods) were developed. By utilizing the reports of the actual results of chip mounter and the notice function of the parts change time, the rate of operation of the chip mounter can be improved.
