This paper considers effective timetable modules in order to easily satisfy various user requirements during scheduling timetables in universities. Noticing that the methods for allocating time blocks change according to the timetable modules, we suggest six models of symmetric timetable modules composed of 4 blocks, and show that our models have more benefits without any loss from the viewpoint of customers, if the suppliers consider the decreasing upper bound of ratio utilizing space resources. By adapting a concept of potentially determined blocks and suggesting their management strategies, finally, we accomplish a method for supporting flexibility and controllability when the universities timetables are scheduled.

Many changes in the railway environment has directly affected to the railway company. To cope immediately with the influence of environment and to promote productivity, the railway company has to introduce an efficient train operation system and related core technologies. The railway system is composed or large-scale infrastructures ann high-cost trains. Simulation method is one or core technologies and also is efficient tool for planning and analyzing this kind of complex system. The purpose of this research is to develop multi-train traffic simulator considering high-speed train for GyongBu-Line. To achieve this objective, the elements of railway system was analyzed, and as a result, a data structure modeling for the railway system such as rail-Tine infrastructure, rain, timetable and operational route is presented. The developed simulator is composed of three major part : input-module, main-module, and output module. The concept and brief explanation of each module will be treated.

PBL is a process and an effective educational tool that empower the student to be an active participant and emphasize a clinical context for learning, developing skills in working with a group, and encouraging self-directed study. The purpose of this study was to develop the PBL module based on lung cancer case, and to evaluate after implementation. The data on lung cancer patients at C university hospital in K city were collected from interviews and nursing records in June, 1999. A PBL module was developed including situation scenarios, timetable and tutor guide. PBL course was conducted at C university for short term period (3 days) in August, 2000. Fourteen nursing students at C college were participated in this study and they were divided into two small groups. I explained them about the PBL course through a preparatory meeting. At a stage of implementation, two groups went through the same process consisting of seven steps with group meetings and self-directed study. Their performances of identifying, stating problems and presenting referred resources were evaluated and supervised by researcher. The PBL course was evaluated by them with questionnaire and essay. Most students responded positively about PBL course and preferred the tutors in a supportive attitude. However, 3 days for PBL course seemed not enough for maximal educational benefits, and many possible problems were discussed. It is necessary for nursing educators to accumulate lots of knowledge and skills regarding creating good working problems and implementing and evaluating diverse PBL tutorials to test the feasibility changing to PBL curriculum.
