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 purpose of this study was to find the preferences on development and management of senior congregate housing according to the preferred developer type. For social survey research, survey was conducted from December 1-20, 2004 in seoul Metropolitan area. The data were collected from m people in 40s-60s using questionnaire which distributed only to those having at least $60\%$ of positive interest in developing the senior congregate housing.'rho results were as follows: First, since majority of respondents wanted to have their old age from mid-60's after retirement more independently, the housing should be designed in a way for them to stay in the m's length of friends and community people. Residential spaces should be individually partitioned and various services should be provided in a semi-dependent manner. The location should be where the medical services were systematically available and ambient environment was agreeable. Second, the cohousing type developers preferred to develop the housing in a form of joint investment with the Potential residents, while the individual developers would like to sell or rent the housing thus would ask for the locations at the outskirts of big cities. In conclusion, most respondents had comparatively similar opinions in terms of the preferred types of development, residential aspects and cost features of the senior congregate housing.

As the need for software development manpower increases, various educational programs appear and the popularity of bootcamp style education program for software development increases. However, despite the operations and forms of bootcamp education programs are completely different from the existing software development education programs, there is a lack of research in understanding bootcamp as a software education program. Therefore, this study tried to derive the core elements of the education program through a case study on bootcamp software developer education program. After conducting interviews of 7 members who have completed a series of bootcamp software developer education program X, seven characteristics of bootcamp-type software development education program were derived: intensive theory education, sense of growth and achievement, team project-based learning, community characteristics, peer pressure, stress and fatigue due to short-term learning, and contact-free specialty. Based on the derived characteristics, the advantages and improvements of bootcamp-type education were described, and the direction of the bootcamp-type education program for software developer was discussed.

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.

In recently, one of the most interests is a field related with serious game. Most game users perform the first for the executing of tutorial before they use a serious game for the first time. But in most case, developers do not recognize importance of tutorial and they do not consider the type of user preference tutorial and make tutorials only as developer's intentions. In our study, we carry out investigation and analysis about type of providing tutorials in representative serious games. Also, we do a survey of users' preferences for types of tutorials. If developers use the result of our study and we can expect more convenient and good quality of tutorial development.

The purpose of this study is to develop a game developer career experience program that promotes student participation and to verify its effectiveness. The game developer career experience education program currently operated by Job World is composed of passive course, which makes students less interesting and only passive activities are possible. In this study, we improved the existing coursework type program to experience actual game development using scratch to promote learner participation. Scratch can be created and shared, giving students the opportunity to create their own work. Therefore, this study developed the game developer career experience education program using scratch and verified its effect. Two Delphi tests were conducted to develop the training program and one expert council was held. In addition, pilot classes were conducted from 22 elementary school students and 30 middle school students, and the satisfaction test was conducted. As a result, the developed educational program showed positive results in terms of help, satisfaction, effectiveness, and awareness.

To inquire its usefulness of the clinical application of intelligent replenishment system of automatic X-ray film processor based on film density, we processed the serial 300 sheets of radiographic film of chest [$14{\times}14"$, HR-C type] and bone [elbow & ankle($8{\times}10"$), skull($10{\times}12"$), hand & foot($11{\times}14"$), pelvis($14{\times}17"$), HR-G type, 68, 70, 77, 85 sheets respectively]. We analyzed the characteristic corves, relative speeds, average gradients and base plus fog densities every twenty five sheets. We also evaluated the developer and fixer replenishment volumes every that time. In the chest and bone radiograph two all, the characteristic curves were little change, and the relative speeds, average gradients and base plus fog densities were within the maximum control limits. The average developer replenishment volumes were about 43m1/sheet and 39m1/sheet respectively. It brings decreased results about 29% in comparison with the conventional replenishment system. In our experiences, we conclude that the intelligent replenishment system of automatic X-ray film processor based on film density maintains image quality consistently, decreases also the replenishment volumes. Therefore, this system will be resulted in economic and environmental effects, and solve problems of over and low replenishment volume.
