The purpose of this study is the examination of the possibility as grasping the circumstance which is the time required from programming to design process in schools which are established newly and investigating the consciousness of the user's participation, because we need a user participation process in the programming to design process to improve the level of design. The above-mentioned purpose is the reason that this study composes the second grade. This study shows the entirely necessary time to work each step as collecting the data of programming-design process to 33 schools which are established for 4 years between 2002 and 2005 by Busan metropolitan city office of education, and the reason why they need a time each step. As the result of this study, the school established by the purpose of land development business takes more time than the school of learning environment improvement and of reconstruction & transfer case. Because of the change of land for school, we have to take a cautious approach to select the land for school in the future when developing the land. The time required from programming to design process in reconstruction & transfer case is the shortest even though it is different a little according to the kind of schools.

Purpose: This study was a descriptive methodological study to develop protocols for school health practice to manage health problems of primary school students effectively. Methods: The protocols were verified by 12 experts and 10 health teachers, respectively, to secure a two-step content validity. Results: The main 8 health problems of primary school students were headache, abdominal pain, musculo-skeletal, respiratory, circulatory, ophthalmic, and oral-dental problems, and fever. The developed protocols consist of 8 algorithms, which are to help decision making in the course of assessing health problems and to identify and link related factors and associated symptoms, 8 school nursing records based on the Omaha classification system, and the list of 441 links between nursing assessment and nursing intervention. Conclusion: The use of the protocols is expected to make it easier for health teachers to apply the nursing process in solving the health problems of primary school students and supporting the rational decision making process, eventually improving the quality of primary school health. Repeated studies for protocol standardization as well as studies dealing with various health problems not included in the protocols should be performed for the development of school health practice protocols.

Two government affiliated research institutes, EDUMAC and AURI, are developing some tools for an user participating design process in public recently. The tools are originated from DQI/DQIfS, launched in 2002 by CIC(Construction Industry Council) in U.K.. At the beginning DQI/DQIfS was not a tool for making a decision but for a communication between layman and experts of architectural process. Because of this intent the most crucial thing is not DQI/DQIfS itself but how to use the tool: CIC is trying to develop various ways of facilitation. Domestic situation is no exception. Without a proper tool there were an independent user participating process in 2001 and it must have been the first participating process in architectural discourse. Through the seven workshops, the users of Namhansan elementary school drew not only the vision of the school but also concrete requirements which have been continuously adopted so far. The aims of this paper to analyse two facilitation processes: DQI/DQIfS in U.K. and the case of Namhansan process. Even not a proper tools for the process there was a spontaneous facilitation in Namhansan process. When we make a comparison between the Namhansan process and the DQI/DQIfS process there are considerable similarities in terms not only of the process itself but also the results. It shows that there are possibilities to make a Korean facilitation in a user participating process and this study must be the first step.

Fluid catalytic cracking (FCC) is an important chemical process that is widely used to produce valuable petrochemical products by cracking heavier components. However, many difficulties exist in modeling the FCC process due to its complexity. In this study, a dynamic process model of a FCC process is suggested and its structural observability is analyzed. In the process modeling, yield function for the kinetic model of the riser reactor was applied to explain the product distribution. Hydrodynamics, mass balance and energy balance equations of the riser reactor and the regenerator were used to complete the modeling. The process model was tested in steady-state simulation and dynamic simulation, which gives dynamic responses to the change of process variables. The result was compared with the measured data from operating plaint. In the structural analysis, the system was analyzed using the process model and the process design to identify the structural observability of the system. The reactor and regenerator unit in the system were divided into six nodes based on their functions and modeling relationship equations were built based on nodes and edges of the directed graph of the system. Output-set assignment algorithm was demonstrated on the occurrence matrix to find observable nodes and variables. Optimal locations for minimal addition of measurements could be found by completing the whole output-set assignment algorithm of the system. The result of this study can help predict the state more accurately and improve observability of a complex chemical process with minimal cost.

This paper is the study on improving the coefficient of utilization of material in deep drawing process. Cylindrical cup drawing process is widely used in sheet metal forming process. The blank shape is one of the important things in sheet metal forming process. It is produced for the bridge of blank in a blanking process. The coefficient of utilization of material is much effected by this bridge of blank. This study offered a new process method to reduce the loss of material. The new blank shape offered and manufactured by new process method is investigated by a finite element method and the experiment. Then the wrinkling, the punch load, the thickness distribution is observed. This result is different from the result of circular blank process. And it is got that the Max strain, the wrinkle and the height of the wrinkle are effected by the holding farce and the punch load. As a result. if the processing optimum condition is found, the loss of material will be reduced. It is necessary to research systematically about determining the optimum vague of process variables.

Drilling process is usually the most efficient and economical method of making a hole in a solid body. However, there have been no analytical method to assess drilling process based on the shear and frictional characteristics. In this paper, procedures for analyzing shear and frictional processes of drilling have been established by adopting an equivalent turning system to drilling. A series of drilling experiments were carried out with varying feed, velocity and drill shape factors. Using the results of the experiments, the cutting characteristics including shear in the primary shear zone and friction in the chip-tool contact region of drilling process have been analyzed. The specific cutting energy tends to decrease exponentially with increase of feed rate. In drilling process 35-40% of the total energy is consumed in the friction process. This is greater than that of turning process in cutting of the same work material.

Although managing knowledge about business processes has been recognized as an important aspect of Knowledge Management System (KMS), it has not been satisfactorily addressed academically or commercially. This paper proposes a KMS architecture to effectively manage business process as knowledge. It expands commonly recognized KMS functions with the process packaging module that defines business processes, monitors and evaluates process instances, keeps process instance history, and provides link between processes and other knowledge items such as documents and experts. The users can not only find the best practice of a business process but also learn from mistakes. A prototype system is implemented to show the feasibility of the proposed architecture. The results of this paper can contribute to expand current KMSs to help use knowledge to enhance the users' performance in their business processes.

The purpose of this study is to investigate a student's career maturity during a career exploration program based on the ecological system perspective and to propose directions for the career maturation process to help H. Meister High School students to get jobs. A single-case 12-session career exploration program was applied to a first-year student at H. Meister High School in U. City for 90 minutes per session twice a week. To verify the effects of the program, this study conducted a pre-test and post-test of career maturity to analyze changes. In addition, the study qualitatively analyzed changes in the program activity sheets and process evaluation sheets per session. The results of the study are as follows: Firstly, the career exploration program based on the ecological system perspective conducted with the student at H. Meister High School improved the student's career maturity. Secondly, changes were observed in the scores in the sub-factors of career maturity between the pre-test and the post-test. Significant differences in the results of the analysis of the sub-factors of career maturity indicate that the program had a statistically positive impact on the career maturation process of the participant. In conclusion, as a result of the in-depth implementation of the program for 12 sessions, the participant expressed his desires which were clarified. In addition, a positive career maturation process appears to have taken place, owing to the self-directed program that led the participant to initiate plans and explore his career by himself. This study was conducted as a single case based on the ecological system perspective concerning career exploration and the career maturation process, but it will be necessary to expand the study to investigate the effects of group counseling, information exchange considering peer influences, common discussions on goal-setting, and other methods on the career maturation process.
