Dental Treatment in a Patient with CINCA Syndrome under General Anesthesia
이지민,송지수,현홍근,김영재,김정욱,장기택,이상훈,신터전,Lee, Ji Min,Song, Ji-Soo,Hyun, Hong-Keun,Kim, Young-Jae,Kim, Jung-Wook,Jang, Ki-Taeg,Lee, Sang-Hoon,Shin, Teo Jeon Korean Academy of Pediatric Dentistry 2018 대한소아치과학회지 Vol.45 No.1
Chronic infantile neurological cutaneous articular (CINCA) syndrome periodically causes fever along with inflammation in multiple organs. Patients with this condition are vulnerable to dental problems due to systemic inflammation. For uncooperative patients, general anesthesia has been widely used to control negative behavior. However, caution should be exercised when administering general anesthesia in these patients because this syndrome is pro-inflammatory. The present case report describes the clinical considerations of the dental treatment of an uncooperative child with CINCA syndrome who was treated under general anesthesia.

Classification results of rural villages provide useful information about rural village characteristics to select similar villages in rural development project; many researches about regional classification have been practiced. Recently rural amenity was introduced as an alternative for rural development, and rural villages have been surveyed to find potential resources for rural development by 'Rural Amenity Resources Survey Project'. Accumulated information through this survey project could be used to classify rural villages. However existing rural classification method using statistical data is not efficient method to use rural amenity resources information described with text. We introduced Information Bottleneck Method (IBM) based on information theory and implemented this method to classification with rural amenity resources information of Yanggang-myen, Yeongdong-gun in Chungbuk province.

오스템퍼링 시간에 따른 초고강도 나노 베이나이트강의 미세조직과 기계적 특성
이지민,황병철,Lee, Ji-Min,Hwang, Byoungchul 한국재료학회 2020 한국재료학회지 Vol.30 No.2
This study deals with the effects of austempering time on the microstructure and mechanical properties of ultra-high strength nanostructured bainitic steels with high carbon and silicon contents. The steels are composed of bainite, martensite and retained austenite by austempering and quenching. As the duration of austempering increases, the thickness of bainitic ferrite increases, but the thickness of retained austenite decreases. Some retained austenites with lower stability are more easily transformed to martensite during tensile testing, which has a detrimental effect on the elongation due to the brittleness of transformed martensite. With increasing austempering time, the hardness decreased and then remained stable because the transformation to nanostructured bainite compensates for the decrease in the volume fraction of martensite. Charpy impact test results indicated that increasing austempering time improved the impact toughness because the formation of brittle martensite was prevented by the decreased fraction and increased stability of retained austenite.

SWAT모형을 이용한 유량 및 유사 예측 정확성 평가 및 최적관리 기법 효과 분석
이지민,류지철,강현우,강형식,금동혁,장춘화,최중대,임경재,Lee, Ji-Min,Ryu, Ji-Chul,Kang, Hyun-Woo,Kang, Hyeong-Sik,Kum, Dong-Hyuk,Jang, Chun-Hwa,Choi, Joong-Dae,Lim, Kyoung-Jae 한국농공학회 2012 한국농공학회논문집 Vol.54 No.1
Soil erosion and sediment from agricultural farmland has caused various negative impacts on environment in recent years. The effect of rice straw mat on soil erosion has been investigated by many researchers these days. In this study, the SWAT model was applied to Hongcheon watershed to evaluate SWAT flow and sediment, and the effect of rice straw mat on sediment yield at watershed outlet was evaluated. The Nash-Sutcliffe model efficiency (NSE) and coefficient of determination ($R^2$) values for flow simulation (calibration period) were 0.66 and 0.67, and the NSE values for sediment was 0.90. The calibrated parameters were used to analyze the reduction of sediment yield in the farmland with rice straw mat. Average daily sediment yield without rice straw mat was 49.8 ton/day and sediment yield with rice straw mat was 25.5 ton/day, and the reduction rate was 38.7 %. Also, average daily sediment yield with/without rice straw mat were 97.5 ton/day and 190.7 ton/day during the rainy season (Jun. 2008 - Aug. 2009), with the reduction rate 46.3 %.

This study is cases study of sustainable eco-friendly cosmetics packages. The importance of eco-friendly packages has been increasing as environmental issues have recently emerged around the world. Domestic cosmetics industry are releasing sustainable package designs with these changes, but they are limited. In this study, sustainable package criteria were divided and analyzed based on each of the five prior studies of domestic and foreign cases. Studies have confirmed that there is no diversity in the materials and designs of sustainable packages in Korea compared with other countries. Also, it could be seen that there was the lack of consumer-led eco-friendly campaigns. Starting point of research, it is expected that this study may help continue to study better sustainable cosmetics packages in the future. 본 연구는 지속 가능한 친환경 화장품 패키지에 관한 사례 연구이다. 최근 전 세계적으로 환경 문제가 대두되면서 친환경 패키지의 중요성이 높아지고 있다. 국내 화장품 업계는 이러한 변화에 발맞춰 지속 가능한 패키지 디자인을 출시하고 있지만, 한정적이다. 본 연구에서는 국내외 사례 각 5가지 선행 연구를 바탕으로 지속 가능한 패키지 기준을 나누어 분석하였다. 연구 결과 국내에는 국외와 비교하여 지속 가능 패키지의 소재와 디자인이 다양하지 않다는 것을 확인하였다. 또한, 소비자 주도의 친환경 캠페인이 부족하다는 것을 알 수 있었다. 이 연구를 기점으로 삼아 앞으로 더 나은 지속 가능한 화장품 패키지에 대한 연구가 계속해서 이루어지기를 기대한다.

알쯔하이머형 치매 환자에서 행동심리증상과 호모시스테인과의 연관
이지민,임우영,김현,이강준,Lee, Ji Min,Im, Woo-Young,Kim, Hyun,Lee, Kang Joon 한국정신신체의학회 2014 정신신체의학 Vol.22 No.1
Objectives : Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to examine the relationship exists between plasma homocysteine concentration and behavioral and psychological symptoms of dementia(BPSD). Methods : 41 subjects with dementia of Alzheimer's type were included in this study. We carried out history taking, physical examination, and cognitive assessment for the diagnosis of dementia of Alzheimer's type based on DSM-IV. We scored the Mini Mental State Examination(MMSE), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), and the Korean Neuropsychiatric Inventory(K-NPI). We also measured levels of homocysteine, folate, and vitamin $B_{12}$ in the plasma. Results : We found statistically significant positive correlations between homocysteine concentration with NPI total score, and with scores of several sub-domains such as delusion, agitation/aggression, depression/dysphoria, and elation/euphoria. No significant correlation existed between homocysteine levels and scores of MMSE, GDS, and CDR. Conclusions : This study shows that plasma homocysteine levels are associated with BPSD. Further research is necessary to identify pathophysiologic mechanisms underlying these relationships.

Three harpacticoid species of the genus Onychocamptus are reported from the inland waters of South Korea: O. vitiospinulosa (Shen and Tai), O. mohammed (Blanchard and Richard) and O. bengalensis (Sewell). Of these, O. vitiospinulosa and O. mohammed are newly added to Korean copepod fauna. Onychocamptus vitiospinulosa is redescribed. Systematic accounts on the morphological details and the intraspecific variabilities are provided with a key to the Onychocamptus species from Korea.
