  • It is very necessary to have a creative problem-solving capacities to learn various majors and liberal arts based on the major, and to solve the bottleneck techniques led by students. In this study, the existing creative problem-solving curriculums, 'Methodology of Inventive Problem Solving' based on TRIZ, were improved and applied, and industrial bottleneck techniques were provided to students to solve these techniques. To improve the curriculum, 1) improvement of instructional objectives and learning contents, 2) improvement of evaluation methods and contents (reflecting the evaluation of instructor and students), and 3) learning satisfaction survey were conducted in the following order. As a result of the application of the improved curriculum, the level of activities for each team was improved, and when the core process was well understood, the evaluation of team activities was also excellent, but there was a tendency to focus on methods that are relatively easy to apply in the problem solving process. In the final exam (learning contents evaluation), teams with difficult understanding of the TRIZ theory or low team activities showed a relatively high trend, but the difference in level between divisions was slightly reduced.

  • A system was established for induction of multi-shoots and plant regeneration from mesophyll protoplasts of alfalfa, Medicago sativa L. cv. Vernal. Different hormonal effects were tested at each step of protoplast culture, i.e. cell division in modified Kao's liquid medium (K566-7). calli formation on SH semi solid medium, and multi-shoot regeneration from calli on SHa and SHb solid media. Frequency of multi-shoots and plant regeneration was affected by various combinations of phytohormones in final step. The evaluation of multi-shoots induction systems via protoplast culture was discused.

  • A case of central neurilemmoma in mandible of 39 year-old Korean male was reported. The final diagnosis was determined by comprehensive evaluation of 1) clinical features of hard swelling, buccally, on right mandibular body region, 2) radiographic features of well- demarcated unilocular osteologic lesion on right mandibular body region, 3) histopathologic features of Antoni type A and Antoni type B, 4) immunohistochemical features of positive to S-100 protein.

  • ISC3는 EPA가 권장하는 가우시안 대기확산 모델로서 일반적으로 공장 배출원으로 인한 일정 기간동안의 대기확산농도와 범위를 예측하기 위하여 사용되어진다. ISC3 모델은 다양한 점오염원, 면오염원, 등을 취급할 수 있을 뿐 아니라 building wake와 down wash 그리고 거리의 함수로써 final plum rise를 옵션으로 사용할 수 있고 단순지형이나 복합지형의 고려가 가능하다. ISC3 모델은 단순지형 장기모델인 ISCLT3와 복합지형 단기모델인 ISCST3가 있으며 모델의 수행에 있어 약간의 차이점이 있다. (중략)

  • Performance demonstration with real flawed specimens has been strongly required for nondestructive evaluation of safety class components in nuclear power plant. Specimen has been designed to produce mechanical fatigue flaw with tension stress and fatigue flaw has been produced to control stress and cycle, for suitable roughness. Notch condition is considered for control of fracture mode. After seal welding for fracture surface, final welding was performed to complete flaw specimen with GTAW(Gas Tungsten Arc welding) and FCAW(Flux Cored Arc Welding). It was demonstrated flaw size of flawed specimen by radiographic. testing and ultrasonic testing.

  • This study conducted a survey for BIM experts as a basic study to improve the efficiency of a BIM-based review of the BF certification evaluation method. By limiting the buildings to elementary schools, the first survey was conducted to extract the mandatory facilities from the BF certification evaluation items according to the evaluation criteria, and 63 out of a total of 94 evaluation items were extracted. The extracted facilities were intermediary facilities, internal facilities, and sanitary facilities. The second survey provided detailed calculation criteria for BF certification evaluation items, and through investigating the possibility of BIM-based review, 31 items were derived. In the 3rd and final survey, when asked about the effectiveness of the current CAD-based and BIM-based evaluation methods, the BIM-based evaluation method showed 96.8% effectiveness and the CAD-based evaluation method showed 3.2% effectiveness.

  • The physicochemical and sensory qualities of pumpkin jams replaced sucrose with sugar alcohols were investigated during storage at 20C. Pumpkin jam was prepared with steamed ground pumpkin, mixed with sucrose only(50%), sorbitol (sucrose 30%+sorbitol 20%) or maltitol (sucrose 30%+maltitol 20%). Final sweetness of each pumpkin jam was 64 Brix. During 60 days of storage there were no differences in acidity and pH among treatments. Reducing sugar content was higher in sucrose, compared to maltitol or sorbitol. During storage, Hunter L, a and b values increased; L and b values were the highest in maltitol and a value were the highest in sucrose compared to the other sugars. Adhesiveness and hardness of textural properties were the highest in sugar and the lowest in maltitol. Sensory evaluation results showed that the mean scores of color, clarity, flavor and overall acceptability were the highest in maltitol, compared to sucrose or sorbitol. Physicochemical and sensory characteristics of pumpkin jams during storage in a PCA plot comprised of first principal component (58.79%) and second principal component (20.94%).

  • On May 10, 2017, Moon Jae-in's Government launched. The election pledges of Moon's Government in healthcare sector were extracted from those of president election camp and Democratic Party. The main pledges were enhancing the coverage of healthcare costs, management of healthcare costs for elderly, restructuring the health insurance contribution system, and improving the public nature of healthcare system. There are many policy tasks to realize the electoral pledge, especially, financial task is main. The National Planning and Advisory Committee are setting the policy priorities and making the detailed plans. Although this paper deals the initial evaluation of main election pledges, the precise evaluation is needed for the final plan of healthcare policy.

  • Hem quality can be determined mainly by turn-down and roll-in. Turn-down, that is created by the elastic recovery, can't be easily detected and measured since it is usually as small as 0.03 m. This study is focused on the precise evaluation of the hemming defects through analytical and experimetal approaches, and on the investigation of the influence of process parameters on the final hem quality. Implicit finite element analysis of plane-strain hemming process is performed by using a commercial code ABAQUS/Standard. Experiment and measurement is also carried out for steel and aluminium sheet metals, and the results are compared with those of analysis.

  • In July 2002, law of product liability will be established in Korea. Therefore, prevention for product liability(PL) will be immediately needed for many companies. So, in this paper, following topics will be discussed: 1) what are product liability and product safety, 2) why they are needed, 3) why important, 4) what's the difference between considering PL and not considering PL for companies, 5 ) what are risk management methods and risk evaluation system, 6) what is SASA(Systematic Approach to Accident Scenario Analysis) method for applying PL, 7) providing a final conclusion and discussion for future PL law.
