It would be necessary to reorganize the system of College of Agriculture to solve these problems. The objective of the study is to construct the direction of reorganization of College of Agriculture in Sunchon National University. For the objective, survey composed of all professors in the Agricultural College and discussions among committee members were adopted. Survey data was collected and analysed. Through the study, reorganization strategies were built as the point of change of college name, administration of school system by unifying departments with similar major area, basic directions in reconstructing the curriculum for the school system, and strategies for the growth of the College. 1) Name of College of Agriculture will be changed to College of Life and Resource Science. 2) College of Agriculture can be reorganized into six schools based on survey, and for more concrete reorganization, additional opinions must be gathered. Number of incoming student can be reduced for school system from 395 at present to 300 (24% reduction). Finely specialized major should be prohibited, but addition of departments or speciality of new research area can be allowed for the establishment of administration of school system. 3) In management of curriculum, foreign language and computer science should be reinforced as general course in the school system. Obligated lecture hours of professor should be reduced, which would enhance the quality of lecture, and offerring lectures with similar subjects should be restricted. Dual major system is going to be allowed. Team teaching and class separation for the same subject should be allowed for the enhancement of lecture quality. In curriculum revision process, committee of curriculum revision in College of Agriculture must be set up and gather opinios for better revision. The committee regulate the credits for the general course, control overlapping or similar subjects among the schools(majors), select lectures for team teaching and the way of class separation in the same subject. They also provide permitted limits of and the way of conducting dual major system. 4) For further growth of the college, the following items should be satisfied. With the limited number of faculties, concentrating facilities and research capability of the college into specialized area is needed to enhance the competitive power of the college. In this study, the committee agreed to select horticultural area in greenhouse as the specialized area. This will be achieved gradually by employing new faculty members with major in this area and conducting cooperative research among faculty members. An extension system to train farmers for the newly developed technologies in agriculture should be established. In this facility, farmers can exchange their experiences among them, and farmers and the university faculty members can conduct experiments to solve problems occurred in farming practices. The extension system consists of division of reasearch, education, advise, information in agricultural area, and diagnosis of pest and diseases. Annual budget of the college largely depends upon the budget from the Ministry of Education. With the limited budget, it is almost impossible for the college to invest into the area where college faculty members intend to for the farmers. Collection of a fund for the growth of the college is needed. This fund can be gathered either from the alumni, faculty members and students or by reinvesting the profit from experimental farm of the college. The system for the reinvestment of the profit from appendges of the college should be established. The condition of research should be improved. This can be achieved by employing full-time researchers as faculty members and reducing lecture load of professors. Building for the center of cooperative research and systematic installation of experimental facility and equipments might also be needed for the improvement.

Risk mitigation strategy by Passive IN-core Cooling system for advanced nuclear reactors

Seo, Seok Bin,Kim, In Guk,Kim, Kyung Mo,Jeong, Yeong Shin,Bang, In Cheol Elsevier 2018 Annals of nuclear energy Vol.111 No.-

<P><B>Abstract</B></P> <P>After the Fukushima accident, the installation of passive safety systems for nuclear power plants becomes necessary as protection against external power failures. Recently, an innovative safety system was introduced by employing a hybrid heat-pipe concept asa Passive IN-core Cooling system (PINCs). The hybrid heat-pipe concept employs the combination of a control rod and a heat pipe to passively shutdown a reactor in an accident condition and simultaneously remove decay heat from the core. As a result, a PINCs can handle the entire accident sequence in a single system, leading to significant enhancement in nuclear reactor safety. In this study, the safety enhancement of various nuclear reactors has been quantitatively evaluated by using the probabilistic safety assessment method (PSA). PSA models of the APR1400, PGSFR, and SMART nuclear reactors developed in Korea, are developed, and a PINCs model has been applied to each reactor. The PSA model of the PINCs has been developed based on the systematic design and configuration of each reactor. In addition, postulated accident sequences where the PINCs operates have been developed in the PSA model. Finally, the consequence of each accident sequence has been quantitatively evaluated in the form of core damage frequency (CDF) and minimal cut set (MCS) for each nuclear reactor. Based on the PSA results, it is confirmed that the application of the PINCs effectively reduces the overall CDF of all nuclear reactors. In addition, the failure paths causing the core damage are restricted for APR1400 and PGSFR. In conclusion, the employment of the PINCs significantly improved the overall safety degrees of various nuclear reactors.</P> <P><B>Highlights</B></P> <P> <UL> <LI> PINCs combines a control rod and a heat pipe to enhance safety of advanced reactors. </LI> <LI> PSA models of advanced reactors are developed including PINCs. </LI> <LI> The consequences of the accident aided by PINCs are quantitatively evaluated. </LI> <LI> PINCs significantly reduces the overall CDFs of all nuclear reactors. </LI> </UL> </P>

목적:급속자기공명영상기법을 이용하여 절제된 정상위벽을 관찰하고,이를 조직소견과 비교 연구하여,위벽의 관찰을 위한 최적기법을 찾고자 하였다. 대상과 방법:25명 환자의 모두 41개 절제된 정상위조직을 수술후 수지(polyethylene)통에 넣고,생리식염수로 채워 자기공명영상을 시행하였다.T1강조FLASH,지방억제T1강조FLASH, T2강조TSE와 True-FISP 등 4가지 기법으로 위조직의 영상을 얻었다.자기공명영상에서는 위벽의 층수와 각층의 신호강도를 관찰하였고,이를 조직소견과 비교하였다.자기공명영상소견을 조직소견과 비교한 후 위벽 각층의 명확성과 각층간의 구분,및 전체 영상의 질에 대하여 비교하였다.4가지 기법 중 가장 좋은 방법은 3,가장 나쁜 방법은 0으로 하여 등급을 판정하였다. 결과:자기공명영상에서 위벽의 층수는 T1강조FLASH에서 2층이 41예 중 6예(14.6%),3층 31예(75.6%),및 4층 4예(9.8%)였고,지방억제T1강조FLASH에서 2층 6예(14.6%)와 3층 35예(85.4%),T2강조TSE에서 3층 24예(58.5%),4층 11예(26.8%),및 5층 6예(14.6%)였으며,True-FISP에서 1층 2예(4.9%),2층 8예(19.5%),3층 23예(56.0%),4층은 4예(9.8%), 및 5층 4예(9.8%)이었다.위벽의 신호강도는 T1강조FLASH와 지방억제T1강조FLASH에서 2층으로 보인 예는 위내강으로부터 고-중등도,3층인 경우는 고-저-고/중등도,4층인 예는 고-저-고-중등도신호강도였다.T2강조TSE에서는 3층으로 보인 예는 등도/고-저-중등도,4 층인 경우는 중등도-저-고-중등도/저,5층인 예는 저-고-저-고-저신호강도였다.자기공명 영상소견을 조직소견과 비교하였을 때 위벽이 3층으로 보인 경우 이것은 “점막층-점막하층-근층 ”에 해당하였다.관찰한 3가지 면 모두에서 T1강조FLASH,지방억제T1강조FLASH,T2강조TSE 기법이 True-FISP보다 통계적으로 유의하게 우수하였다(p=0.001).점막층의 명확성에 있어서 가장 우수한 기법은 T1강조FLASH와 지방억제T1강조FLASH이었고(p<0.05),점막하층의 명확성과 점막하층과 근층간의 구분은 T2강조TSE가 가장 우수하였다(p<0.05).전체적인 영상의 질은 T1강조FLASH와 T2강조TSE에서 가장 우수하였다(p<0.05). 결론:자기공명영상은 위벽의 각 층을 구별할 수 있는 우수한 검사로 조직소견과 높은 연관성을 보이며,전체 영상의 질,점막하층의 명확성 및 점막하층과 근층간의 구분이 T2강조TSE에서 가장 우수한다. Purpose: To evaluate normal human gastric wall layers in vitro using magnetic resonance*(MR) imaging, to correlate the results with the histologic findings, and to determine the optimal technique for evaluation of the gastric wall. Materials and Methods: Forty-one normal resected gastric specimens obtained from 25 patients were dissected and placed in a polyethylene tube filled with normal saline. MR imaging with four MR sequences, T1-weighted FLASH*(T1FLASH), fat-saturated T1-weighted FLASH, T2-weighted TSE*(T2TSE), and True-FISP, was performed. The number of gastric wall layers and signal intensity of each layer were determined, and after correlating MR images with the histologic findings, the conspicuity of each layer*(mucosa, submucosa, and muscle), the distinction between each layer, and overall image quality were assessed. results: The gastric wall was shown by TIFLASH to have two (n=6, 14-6%), three (n=31, 75.6%) and four layers (n=4, 9.8%); by fat-saturated TIFLASH to have two (n=6, 14.6%) and three (n=35, 85.4%) ; by T2TSE to have three (n=24, 58.5%), four (n=11, 26.8%), and five (n=6, 14.6%); and by True-FISP to have one (n=2, 4.9%), two (n=8, 19.5%), three (n=23, 56%), four (n=4, 9.8%), and five (n=4, 9.8%) . The signal intensity of each layer at T1FLASH and fat-saturated T1FLASH was high-intermediate from the lumen in two-layer cases, high-low-high/intermediate in three-layer cases, and high-low-high-intermediate in four-layer cases. The signal intensity of each layer at T2TSE was intermediate/high-low-intermediate in three-layer cases, intermediatelow-high-intermediate/low in four-layer cases, and low-high-low-high-low in five-layer cases. Three-layered gastric wall corresponded mostly to mucosa, submucosa, and muscle from the inner to outer layers, respectively. T1FLASH, fat-saturated T1FLASH, and T2TSE were superior to True-FISP in evaluating the gastric wall. T1FLASH and fat-saturated T1FLASH were the best sequences for demonstrating mucosa (p<0.05), and T2TSE was the best for submucosa and the distinction between this and muscle (p<0.05). Both T1FLASH and T2TSE provided the best overall image quality (p<0.05). Conclusion: In-vitro MR imaging is an excellent technique for the evaluation of layers of normal gastric wall. T2TSE is the sequence which best demonstrates the conspicuity of submucosa, the distinction between submucosa and muscle, and overall image quality.

To accomplish these goals, 90 students, the number of two classes of the first grade at P high school at Anyang city of Kyonggi province were selected. They are composed of the experimental group and the comparative group. Each group contained 40 students. The former was implemented by indirect instructions and the latter direct instructions. The 'family and Domestic Life' unit of the first grade was selected as the study subject to take effects and 30 periods of class were enforced. For the experimental measure of this study, the researcher used a pre-learning test, a learning attitude test, and a learning achievement test as means of measure. The two groups were confirmed as the group having the same quality.

The results are following: 1. The direct and the indirect instructions represented the meaningful differences in the learning achievements (p <.05). They represented the meaningful differences in improving the learning achievements of knowledge and understanding(p <.05). It was verified that the former is more effective than the latter in improving the learning achievements of knowledge and understanding. and They represented the meaningful differences in the improving learning achievements of application(p <.05). 2. They represented the meaningful differences in the learning attitudes at a domestic class(p< .05) The latter is more effective than the former in changing into the positive learning attitudes. In the light of these results, the direct instructions are effective in improving the learning achievements of knowledge and understanding, and the indirect instructions are effective in improving the learning achievements of application.
