KAERI has been operating an integral effect test facility, ATLAS (Advanced Thermal-Hydraulic Test Loop for Accident Simulation), for accident simulations of advanced PWRs. Regarding integral effect tests, a database for major design basis accidents has been accumulated and a Domestic Standard Problem (DSP) exercise using the ATLAS has been proposed and successfully performed. The ATLAS DSP aims at the effective utilization of an integral effect database obtained from the ATLAS, the establishment of a cooperative framework in the domestic nuclear industry, better understanding of thermal hydraulic phenomena, and an investigation of the potential limitations of the existing best-estimate safety analysis codes. For the first ATLAS DSP exercise (DSP-01), integral effect test data for a 100% DVI line break accident of the APR1400 was selected by considering its technical importance and by incorporating comments from participants. Twelve domestic organizations joined in this DSP-01 exercise. Finally, ten of these organizations submitted their calculation results. This ATLAS DSP-01 exercise progressed as an open calculation; the integral effect test data was delivered to the participants prior to the code calculations. The MARS-KS was favored by most participants but the RELAP5/MOD3.3 code was also used by a few participants. This paper presents all the information of the DSP-01 exercise as well as the comparison results between the calculations and the test data. Lessons learned from the first DSP-01 are presented and recommendations for code users as well as for developers are suggested.

본 연구는 인삼재배지 포장에서 부엽토와 돈분퇴비 시용이 토양생물에 미치는 영향을 조사하고자, 토양미생물, 선충, 응애 등 미소동물의 군집과 개체밀도의 변화를 관찰하였다. 토양 미생물 군락 조성과 생태를 조사하기 위하여 인지질지방산을 추출하여 지표지방산으로 분석한 결과 세균, 곰팡이, 방선균의 상대밀도는 차이가 없었다. 부엽토 처리구에서 환경스트레스 지표인 포화지방산/단불포화지방산 비율과 Cyclopropyl 지방산/전구체 지방산 비율이 높게 나타났으며, 호기성/혐기성균 비율이 낮았던 것은 유기물의 분해속도가 느리다는 것을 시사한다. 돈분퇴비 처리구에서 내생균근균인 VAM의 상대밀도 증가는 pH 증가의 영향으로 보이지만, 유기물증가에도 불구하고 그램음성균/그램양성균 비율과 스트레스 지표가 대조구와 차이가 없었던 것은 EC나 pH 증가 등으로 인한 토양의 이화학성 변화에 의한 결과로 보인다. 돈분퇴비 시용구에서 선충의 개체밀도는 증가하였지만, 날개응애류의 개체밀도는 감소하였다. 부엽토 또는 돈분퇴비의 시용에도 불구하고 토양동물의 개체밀도는 일반 농경지와 비교할 때 매우 낮은 수준으로 나타났으며, 개간지의 경우 장기간의 예정지 관리를 통해 토양생물의 밀도를 높여 유기물의 분해효율을 증가시키는 과정이 필요할 것으로 판단된다. The aim of this study is to evaluate the effects of organic materials on soil organisms. Changes in the community structure, and population density of soil organisms (microbes, nematodes, and microarthropods) were studied in a Korean ginseng field. Phospholipid fatty acids analysis showed that the relative abundances of bacteria, fungi, and actinomycetes did not differ significantly. The aerobes/anaerobes ratio was the lowest in soils amended with leaf mold, indicating that the decomposition speed was slow. Further, the addition of leaf mold to the soil enhanced the saturated/monounsaturated fatty acid ratio and cyclopropyl fatty acid/precursor ratio, which indicated an increase in environmental stresses. Application of pig manure compost (PMC) had positive effects on the population density of nematodes, and negative effects on that of oribatid mites. The population densities of nematodes, and microarthropods remained relatively low in the plots that had been treated with leaf mold or pig manure compost. It is suggested that pre-planting soil management directed at enhancing the biological decomposition efficiency should be continued over a long period to increase the soil bioactivity in virgin soils.

Background: Temporomandibular joint (TMJ) ankylosis during early childhood may lead to disturbances in growth and facial asymmetry and to serious difficulties in eating as well as in breathing during sleep. The purpose of this study is to describe the effectiveness of an interocclusal splint (IOS) for active mouth opening exercises in the treatment of TMJ ankylosis. Methods: A total of nine patients with 13 instances of TMJ ankylosis from 2008 to 2010 were included in this study, of which five patients were male and four patients were female. Five patients demonstrated unilateral ankylosis, while five patients showed bilateral symptoms. Ankylosed mass resection with coronoidectomy, fibrotic scar release, and resection of stylohyoid ligament calcification was performed with gap arthroplasty without an interpositional graft, and all patients were assessed for maximum mouth opening (MMO) during a mean 6.6-year follow-up period. Results: All patients were subjected to postoperative mouth opening exercises from the day of the operation with the help of an IOS, which was based on an impression taken during surgery. All patients were sufficiently comfortable moving their mandible according to the IOS's guiding plane and impingement, and satisfactory results were achieved, in which MMO was improved by 35 mm more than 6 years after surgery. Conclusions: Complete and adequate resection of the ankylosed mass and postoperative active mouth opening exercises are essential in the treatment of TMJ ankylosis. Moreover, a more comfortable mouth opening guide and interdigitation can be achieved using an IOS, and newly organized fibrosis in the gap space between the newly made resected condylar head and temporal fossa can be suggested.

Background: To identify work-family balance and level of happiness among married women dental hygienists in Seoul and Gyeonggi Province. The goal of this study is to use the outcome as basic data to determine the compatibility of dental hygienists with work and family, systems, and improvement of happiness levels. Methods: From July 3 to August 10, 2020, 250 dental hygienists in Seoul and Gyeonggi Province were targeted. The questionnaire comprised 65 questions, including general characteristics (perception of work-family balance, perception of work-family balance system, job satisfaction, parenting type, happiness level) whether or not they were implemented. The results were obtained through a self-control questionnaire. Results: The perception of work-family balance was significantly different in job rank and average income, while that of the work-family balance system had significant differences in workplace type, total work experience, current job work experience, childcare system status, and parental leave period. Happiness level and job satisfaction were significantly different in job rank, average income, and childcare system status. Additionally, the perception of work-family balance and that of the work-family balance system showed a positive correlation with job satisfaction and happiness level. Finally, the perception of married women dental hygienists toward work-family compatibility was determined, where the higher the satisfaction with the job, the higher the level of happiness. Conclusion: To improve the work-family balance and job satisfaction of dental hygienists and their levels of happiness, changes in social perception and improvement of the working environment such as proper staffing, flexible work systems, and incentive systems should be considered.

This study aims to examine the transfer passage in subway station in Seoul Metropolitan area by ordinary end users" viewpoints for analyzing and suggesting improvements of facility conditions. This study conducted a survey using a checklist which based on the current studies. Contents of the checklist divided into four different emotional design elements, satisfaction, esthetic, space, and identity. The field survey was assessed according to analyzing evaluation summaries and suggesting problems. The first, satisfaction, it required the design solution reflected the excitement of sensibilities of users’ bodies’ reaction such as sight, hearing, and touch. The second, the storytelling method may arouse users" interest and maximize the advertising effect. The Third, the space need to improve with natural elements to minimize the stifling atmosphere. The Fourth, designers should consider designing the space to be stimulated to take an interest in new experience to end users by providing special event which represent the subway station.

Zoysiagrass (Zoysia japonica Steud.) is one of the most popularly cultivated grasses for sports and recreational environments, particularly in warm region. Zoysiagrass has a tardiness of vegetative propagation compared to other turfgrass. Thus farmers and green keepers want to quickly recognize the field information for management. We discuss the design of a Morphologic-Aware Self-Adaptive (MASA) system for zoysiagrass agricultural business. MASA system with image analysis technique is able to rapidly detect grass blade color and length variations caused by changing climate and environment stress. In the future, farmers and green keepers will be able to have smart-farming and smart-management with MASA system.
