Positive type presensitized offset plate developer were blended by quantitative analysis method. The test had been proceeeded to check variation of developability, shelf life and tone reproduction by SiO2/Na2O ratio to PS plate developer, added glycerin, and sodium phosphate with glycerin. This study of tone reproduction had been tested 5 times to get accuracy by PS platesusing kodak CCG C-3, KMS. The test result of tone reproduction of presensitized offset plates can be summarized as follows ; major compositions in positive type plate developer were Na, Si, K and P, developability were increased by Sio2/NaO2 ratio in positive type plate developer. Shelf life can be kept by add glycerin to positive type plate developer. Tone reproduction were improved by sodium phosphate due to buffer action while shelf life can be kept by add glycerin in positive type plate developer.

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.

소프트웨어 개발 인력의 필요성이 높아지면서, 다양한 교육 프로그램들이 등장하고 있으며, 그 중 신병캠프를 의미하는 부트캠프(bootcamp) 스타일의 교육 프로그램의 인기가 두드러지고 있다. 하지만 기존의 소프트웨어 개발 교육 프로그램들과는 운영 방식이나 형태가 완전히 다름에도 불구하고, 교육 프로그램으로써 부트캠프를 분석한 연구는 부족한 실정이다. 이에 본 연구는 부트캠프형 소프트웨어 개발자 교육에 대한 사례 연구를 통해 해당 교육 프로그램의 주요 요소를 도출하고자 하였다. 이를 위해 A사의 부트캠프 프로그램 X의 수료자 7명을 대상으로 인터뷰를 진행한 뒤, 부트캠프형 교육의 7가지 특징을 도출하였다. 집중 이론 교육, 성장과 성취감, 팀 프로젝트 기반 학습, 커뮤니티 특성, 집단 압력, 피로도와 압박감, 비대면 특수성. 도출한 특징을 바탕으로 부트캠프형 교육의 장점과 개선점에 대해 기술하고, 부트캠프형 소프트웨어 개발자 교육이 나아갈 방향에 대해 논하였다.

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.

최근 가장 많은 관심을 받고 있는 분야 중 한 가지는 기능성 게임이다. 대부분의 게임 사용자들은 그들이 처음으로 기능성 게임을 사용하기에 앞서 가장 먼저 하는 일은 튜토리얼을 실행하는 일이다. 그러나 대부분의 경우에 있어, 개발업체들은 튜토리얼의 중요성은 인식하지 못하고 있으며 사용자들이 선호하는 튜토리얼의 유형을 고려하지 않은 채 개발업체의 의도대로만 개발을 하고 있다. 본 연구에서는 대표적인 기능성 게임들이 제공하고 있는 튜토리얼의 유형에 대한 조사 및 분석을 실시하였다. 또한, 사용자들이 선호하는 튜토리얼 유형을 조사하였다. 연구 결과를 개발업체들이 활용한다면 보다 편리하며 우수한 품질의 튜토리얼 개발을 기대할 수 있을 것이다.

본 연구의 목적은 학습자 참여를 촉진하는 게임 개발자 진로체험 프로그램을 개발하고 그 효과를 검증하는 것이다. 현재 잡월드에서 운영하고 있는 게임 개발자 진로체험 교육 프로그램은 수동적인 코스로 구성되어 있어서 학생들의 흥미가 떨어지고 수동적인 활동만 가능하다. 본 연구에서는 학습자 참여를 촉진하기 위해 기존의 코스워크형 프로그램을 스크래치를 활용한 실제 게임제작을 체험하는 형태로 개선하였다. 스크래치는 창작과 공유가 가능하므로, 학생들에게 자신의 작품을 만들 수 있는 기회를 제공할 수 있다. 따라서 본 연구에서는 스크래치를 활용한 게임 개발자 체험 교육 프로그램을 개발하고 그 효과를 검증하였다. 교육 프로그램을 개발하기 위해 2회 델파이 검증을 거쳤으며, 1회 전문가 협의회를 실시하였다. 또한, 초등학생 22명, 중학생 30명을 대상으로 파일럿 수업을 실시하고 만족도 검증을 실시하였다. 연구 결과, 개발된 교육 프로그램은 도움여부, 만족도, 효과성, 인식도에서 긍정적인 결과를 보였다.

The recent control system has been changed into the type of PLC(Programmable Logic Controller) control. Up to now, systematic approach of PLC programming or control logic design is not suggested. In this study, the design process of the control logic is systematized and concrete process in each step is suggested. This systematized approach lead developer to be convenient to implement control system. When some error is occurred in the system, this approach enable the developer to analyze the reason of error rapidly and the system is amended according to systematic information of the analysis. The example of control system implementation following this approach is introduced.

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.
