  • Purpose: Generally, since the population density is lower in suburban areas, the distance to school is inevitably long. Therefore, schools in suburban areas often operate school buses to improve student welfare. However, since school buses are usually used only during going to and from school, the utilization rates are relatively low. Therefore, this study aims to establish integrated operation plan of public school bus covering all schools. Methods: It is necessary to decide which school buses will serve the specific demand node which want to go to certain school in order to design an integrated operation plan for school buses. Therefore, a mathematical model is developed for minimizing the total number of vehicles and the distance of transportation by reflecting the characteristics of school buses and students as constraints. To solve the proposed mathematical model, CPLEX, a commercial solver, is applied. Results: To validate and to confirm the proposed process, numerical example is designed with the comparison between before and after integrated operations of school buses in terms of total operation cost. The result shows that the integrated operation can lead the reduction of the number of school buses as well as the decreasing of the fuel cost. Conclusion: This study provides the quantitative method to perform the integrated operation of school buses in suburban areas. The optimal operation strategy is required because there are more complex decision-making elements considering the integrated operation. It is expected to apply this research result at real situation to expand this services based on an optimal operation.

  • This study considers the stages of curriculum development for the integrated curriculum of Pusan National University Graduate School & Hospital of Korean Medicine, and specifically the KAS2021 (announced in 2019), improvement measures for the curriculum of the College of Traditional Korean Medicine, and the case of the College of Medicine. The introduction of integrated curriculum in the College of Traditional Korean Medicine starts from the members (doers)' agreement. In the process of development, the organization that represents the members, the organization that sets up a goal and designs the curriculum, and the organization that executes them should fulfill their own roles. The stage of development and operation should have the support system for manpower, institution, administration, and finance. The curriculum (draft) should be concrete enough to be operated in reality. For the smooth operation of integrated education, it is necessary to secure more full-time teachers than before, and it is also necessary to have an organization fully in charge of monitoring and improving the operation. For the introduction and operation of integrated curriculum in Traditional Korean Medicine education, the members' agreement, institutional change, support system, and the cultivation of manpower for the operation/evaluation/development of curriculum should be considered.

  • For economic evaluation of integrated operation to sewage facilities, benefit-cost analysis was performed to watershed sewage works project in 7 watershed areas, 156 facilities. In this study, the cost before and after integrated operation was compared and benefits are calculated from the reduction of operators, increasement treated pollution loads, reduction cost through operation convenience, reduction water consumption through effluent reuse, and improvement of life benefit. The result showed that cost was 8,500million won and benefit was 16,747million won, so benefit was 49% higher than cost. B/C analysis result showed that B/C ratio was 1.97 and it is similar to other researches. The benefits of integrated operation included convenience of data management, increase of emergency response, decrease of complains with sewage which was not reflected numerically, so the benefits of integrated operation were expected much greater than this result

  • Integrated operation schools were introduced to Korea in 1998 with an operation of eight schools, and their number has now increased to 106 and is still growing. Although various problems have been pointed out in research on integrated operation schools over the past two decades, these have not been reflected today. Therefore, the purpose of this study was to comprehensively summarize the concepts, backgrounds, recent status, types, etc. of the integrated operation school and to present its problems in terms of curriculum, teacher management, student management, operation and management of educational facilities, and law and policy through literature review and to propose measures for improvement. This allowed us to compare the concerns of the integrated operation school with the results of the actual research and organize improvement measures.

  • The inefficient operation of Busan New Port is due to container-terminal operators being dispersed in small groups, rather than being integrated. This dispersion increased following the reorganization of global shipping alliances in 2016 and causes unnecessary Inter-terminal Transportation(ITT) and ship delays. Studies of integrated operations for larger container terminals show that integration is not going well, however, due to the pre-emptive task that follows the integrated operation. Therefore, in this study, we divided the integrated operation into stages based on a simulated model of the container terminals in Busan New Port. The simulation took into account future increases in the ship's enlargement and terminal congestion, and the operational effects of each type of integrated operation were analyzed and evaluated.

  • In case that any jobs in a Job Shop can be scheduled on more than one machine and may have flexible operation sequences, with considering such case it is very difficult and complex to make the optimal process plans and scheduling. But they should be considered for an integrated model to perform more effective process planning and scheduling in this job shop problem. In this paper, we propose GA-based scheduling method to integrate effectively the problem of alternative machines, alternative operation sequences and scheduling. The performance of proposed GA is evaluated through comparing integrated scheduling with not integrated scheduling in molding company with alternative machines and operation sequences. Also, we use benchmark problems to evaluate performance. The scheduling method in this research will apply usefully to real world scheduling problems.

  • This study examines the background and necessity of the product certification (KS) and the system authentication (ISO 9000), and their characteristic so as to compare and analyze the possibility of interaction of product certification and system authentication. It tries to suggest an efficient operation system as an integrated management system and analyzes the certification case of K, a manufacturer of kitchen utensils. We believe that the study will help companies minimize their expenses and efforts to establish, operate, and maintain the corporate standard system. In addition, to effectively achieve our goal, we have also made a study of both literature and case and suggested technical guidance to get integrated management system certification. By these methods, we analyzed the effects and problems that come with the introduction and application of the integrated system of product certification and system authentication in order to set up a system to fit to the mechanism of Korean companies. Moreover, we have suggested the model of integrated operation and the benefits that come after acquiring certification.

  • In this paper, an engine-CVT integrated control algorithm is suggested by considering the inertia torque and the CVT ratio change response lag in acceleration. In order to compensate for drive torque time delay due to CVT response lag, two algorithms are presented: (1) an optimal engine torque compensation algorithm, and (2) an optimal engine speed compensation algorithm. Simulation results show that the optimal engine speed compensation algorithm gives better engine operation around the optimal operation point compared to the optimal torque compensation while showing nearly the same acceleration response. The performance of the proposed engine-CVT integrated control algorithms are compared with those of conventional CVT control, and It is found that optimal engine operation can be achieved by using integrated control during acceleration, and improved fuel economy can be expected while also satisfying the driver's demands.
