  • The advanced planning and scheduling(APS) is an well known enterprise information system that provides optimal production schedules and supports to complete production on time by solving the complex scheduling problems including capacity and due dates. In this paper, we focused on the improvement of the APS that is already established on a real company. The existing APS had several drawbacks, thus utilization and satisfaction were very low. We performed the focused group interviews and the process analysis and could find that the end users and developers have various objectives and the frequently used functions are different. We applied the analytical hierarchy process(AHP) to converge opinions of them on quantitative data. The results show that it is necessary to enhance visibility, to improve user interfaces and response speed, and to reconcile the real business process and the APS's process.

  • In order to understand the functional role of CPRl in Saccharomyces cerevisiae KNU5377 with regard to its multi-tolerance characteristics against high temperatures, inorganic acids, and oxidative stress conditions, whole cellular proteins were analyzed via liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). This procedure was followed by two-dimensional (2-D) gel electrophoresis. Under menadione stress conditions, the 23 upregulated proteins were clearly identified only in the wild- type strain of KNU5377. Among the proteins, Sodl1p Tsa1p, Ahp1, Cpr1p, Cpr3, Ssb2p, and Hsp12p were identified as components of antioxidant systems or protein-folding related systems. The CPR1 protein could not be completely detected in the $cpr1{\Delta}$ mutant of KNU5377 and the other upregulated proteins in the wild-type strain evidenced a clear correlation with the results of immunoblot analysis. Moreover, a reduction in growth patterns (about 50%) could be observed in the $cpr1{\Delta}$ mutant, as compared with that of the wild-type strain under mild MD stress conditions. These results indicate that the upregulation of CPR1 may contribute to tolerance against MD as an inducer of oxidative stress.

  • This study aimed to analyze the selection criteria and priority settings for solid culture medium used in hydroponic crop production in farm households. Expert brain storming was carried out to extract solid culture medium selection criteria for hydroponic farming. As a result, 3 criteria of economy (cost), productivity, and environment, and 9 factors were extracted. A questionnaire survey of hydroponic farm households was conducted in Gyeonggi, Gangwon, and Chooncheong provinces. AHP analysis of the hydroponic solid culture medium selection criteria identified productivity as the most important criterion, chosen by 58.7% of the respondents, followed by economy (28.4%) and environment (12.9%). The 9 factors were rated by the respondents in the following decreasing order of importance: 1, crop yield (28.3%); 2, pest occurrence (18.5%); 3, maintenance/management costs (12.0%); 4, convenience of maintenance/management (13.4%); 5, initial investment cost (11.6%); 6, material energy consumption (6.5%); 7, waste recyclability (4.0%); 8, waste disposal costs (3.4%); and 9 environmental emissions (1.81%). These results imply that hydroponic farm households consider cultivation-related quality factors more important than economic factors, such as price of culture medium or installation cost.

  • The purpose of this study is to analyze the necessity of organizing an exclusive unit to perform the division Engineering Reconnaissance, and how to organize exclusive unit. To this end, first, it was analyzed whether exclusive unit organization was necessary by using organization-conditions and AHP. Next, through ARENA model simulation and task-analysis, it was determined how many people would be organized, and how the class structure would be appropriate. As a result, first, it is reasonable to organize the Engineering Reconnaissance unit as an exclusive unit, and the best way is to organize all-time(war/peace time). Second, the exclusive unit should be organized into a total of 10 persons(2~3 cadres, 7~8 soldiers). We hope that the research will contribute to the rational procedure of our military unit structure organization and set the standards for applying the quantitative methodology.

  • 본 연구는 댐 후보지에 대한 우선순위 분석이 결측 정보에 따라 다기준 의사결정 방법 및 결측정보 접근방법에 따라 어떻게 달라지는지를 조사하였다. 전략환경평가(Strategic Environmental Assessment, SEA)는 한국의 댐 건설 장기 계획에서 환경 및 생태학적 영향을 기반으로 한 지속가능한 댐 후보지 선정에 적용되고 있다. 그러나 특정 정보가 결측된 경우 SEA는 댐 후보지를 선정하는 데 어려움이 있다. 본 연구에서는 다기준 의사결정 방법으로 AHP, ELECTRE III, PROMETHEE II, Compromise Programming을 적용하였고, 결측 정보 보완을 위해 이항분포와 균등분포형을 사용하였다. 본 연구에서는 전국의 댐 선정 후보지에 적용하여 다중 기준 의사 결정기법과 정보 생성 방법에 의존하여 결과를 비교하였다. 그 결과, 이항분포형을 적용한 결과가 균등분포형을 적용한 결과보다 보다 명백한 우선순위를 보여 주었다. 또한, 다기준 의사결정방법에 따라서는 댐선정 후보지 결과가 달라지지 않는 것으로 나타났다. 따라서, 다기준 의사결정방법 적용시, 결측 정보를 생성하기 위해 이항분포를 사용하면 균등분포 적용시보다 우선순위를 제공하는데 더 효과적이라고 판단된다.

  • Purpose: This study aimed to present the learning items of indirect practice as an alternative means of ambulance riding practice. Methods: Twelve on-site professionals participated in testing the effectiveness of learning items of utility value in indirect experience practice among the recommended learning objectives of ambulance ride practice using the modified Delphi technique. To validate the learning objectives, the Delphi technique was used to check content validity, and analytic hierarchy process (AHP) analysis was used to analyze the weighting value. Results: As the learning goal of indirect experience practice replaced the ambulance riding practice, four items were derived in consideration of practicality. These items were consistent with the Delphi panel's consistency index, convergence, and agreement. The first learning item to consider was 'Prevention of infection and risk of infection.' Conclusion: The results of this study are meaningful in that they propose the learning items that can achieve the minimum educational goal through indirect experience practice as an alternative means of ambulance training.

  • The Wetland Conservation Plan is used as a tool to set the management direction of wetland protected areas, and which is establishing a plan for the conservation, wise-use, and management based on wetland's condition. This study was conducted to establish a conservation plan considering the functions and management conditions of Upo wetland protected area. To this end, there are analyzed the current issues, plans and implementation status of Upo Wetland Conservation Plans in the past. The management elements to be considered in establishing the Wetland Conservation Plan were selected through prior research analysis and the priority of those elements was identified through the AHP. As a result, it was found that lack of considering the changes and performance evaluation of the existing plans in wetlands, conducting short-term projects related to maintenance original function of wetland, different management methods for wetland protected areas and other adjacent areas, lack of understanding and cooperation by stakeholders, inconsistencies in timing of the Conservation Plan and survey of wetland protected areas. In order to improve the problem, it needs to include the performance evaluation stage of establishing the conservation plan, strengthen cooperation of stakeholders and expertise, continuing of projects for wetlands' maintenance, priority of the project considering the management side, and to adjust the timing of plans to improve data availability.

  • Evaluating the stability of the excavation face of the cross-river shield tunnel with good accuracy is considered as a nonlinear and multivariable complex issue. Understanding the stability evaluation method of the shield tunnel excavation face is vital to operate and control the shield machine during shield tunneling. Considering the instability mechanism of the excavation face of the cross-river shield and the characteristics of this engineering, seven evaluation indexes of the stability of the excavation face were selected, i.e., the over-span ratio, buried depth of the tunnel, groundwater condition, soil permeability, internal friction angle, soil cohesion and advancing speed. The weight of each evaluation index was obtained by using the analytic hierarchy process and the entropy weight method. The evaluation model of the cross-river shield construction excavation face stability is established based on the idea point method. The feasibility of the evaluation model was verified by the engineering application in a cross-river shield tunnel project in China. Results obtained via the evaluation model are in good agreement with the actual construction situation. The proposed evaluation method is demonstrated as a promising and innovative method for the stability evaluation and safety construction of the cross-river shield tunnel engineerings.
