Objectives : Administration methods of antibiotics implements a variety for indications and diseases. Therefore, it is impossible to produce a single guideline. Many antibiotics have been prescribed without specific index, by practicians for a long period of time. In general dental practice and oral and maxillofacial surgical practice, there is not a guidelines for antibiotics. Therefore, there is a dependency on pre-existent methods rather than following an exact guideline. Consequently, a controversy was issued that prescription of antibiotics tend to be misused or abused. And it is also direct relation to the tolerance of antibiotics as well. Moving forward, in this review we will be analyzing the exact usage and indication of antibiotics in dental treatment. Materials and Methods : 29 published articles of both domestic and international were researched through Pubmed and Kormed, and the review from these articles were performed accordingly. We examined the administration of antibiotics through the objective usage, that classified prophylactic and therapeutic. Results : For therapeutic usage, empirical prescription is mandatory for the first step. Next is to moderate the empirical prescription depending upon the result of its culture. Administration of antibiotics must be kept for 2days after the symptoms disappear. For a prophylactic use, we can generally pr escribe antibiotics to prevent local infection or systemic infection. Although the method of prescription and neccessity of antibiotics to prevent local in fection are controversial, exact guidelines of antibiotics to prevent systemic infection are established by AHA. Conclusion : Most crucial concept for prescript antibiotics is to determine if it is adequately suitable for all circumstances. In this decision making, a guideline for prescription of antibiotics in various dental surgical practice is necessary. This guideline can reduce the misusage and disusage of a ntibiotics in general dental practices and oral and maxillofacial surgical practices.

Background: Recently, the use of ultrasound (US) techniques in regional anesthesia and pain medicine has increased significantly. However, the current extent of training in the use of US-guided pain management procedures in Korea remains unknown. The purpose of the present study was to assess the current state of US training provided during Korean Pain Society (KPS) pain fellowship programs through the comparative analysis between training hospitals. Methods: We conducted an anonymous survey of 51 pain physicians who had completed KPS fellowships in 2017. Items pertained to current US practices and education, as well as the types of techniques and amount of experience with US-guided pain management procedures. Responses were compared based on the tier of the training hospital. Results: Among the 51 respondents, 14 received training at first- and second-tier hospitals (Group A), while 37 received training at third-tier hospitals (Group B). The mean total duration of pain training during the 1-year fellowship was 7.4 months in Group A and 8.4 months in Group B. Our analysis revealed that 36% and 40% of respondents in Groups A and B received dedicated US training, respectively. Most respondents underwent US training in patient-care settings under the supervision of attending physicians. Cervical root, stellate ganglion, piriformis, and lumbar plexus blocks were more commonly performed by Group B than by Group A (P < 0.05). Conclusions: Instruction regarding US-guided pain management interventions varied among fellowship training hospitals, highlighting the need for the development of educational standards that mandate a minimum number of US-guided nerve blocks or injections during fellowships in interventional pain management.

이 연구는 요인분석만으로 개발되는 척도의 단점을 보완하는 Rasch 모형을 적용하여 한국 성인에게 타당한 비만위험측정척도를 개발하는데 목적이 있다. 이 연구에서 개발하는 비만위험측정척도에 신뢰성과 타당성을 높이기 위해 서로 다른 연구대상으로 예비검사와 본검사를 실시하였다. 예비검사는 서울지역 성인 336명을 대상으로 실시하였고, 본검사는 서울, 경기지역 성인 680명을 대상으로 실시하였다. 분석프로그램으로는 SPSS 15.0 프로그램과 Winsteps 3.62 프로그램을 사용하였다. 검사내용에 기초한 증거로 개발된 비만위험측정 28문항의 탐색적요인분석 결과 요인적재치가 .4이하인 7문항을 제거하고 최종 6요인 21문항(신체활동 5문항, 식사습관 4문항, 간식습관 3문항, 식탐 3문항, 심리 3문항, 유전 3문항)으로 나타났다. 요인별로 Rasch 모형에 기본가정인 일차원성을 검증하기 위해 주성분분석을 실시한 결과 요인별로 각 문항 모두 일차원성을 만족하는 것으로 나타났다. Rasch 모형 분석을 통한 문항적합도 분석 결과 신체활동 요인에서 한 문항(활발하지 않고 소극적이다)의 내적합지수(infit)와 외적합지수(outfit)가 모두 1.3을 초과하는 것으로 나타났으며, 식사습관 요인에서 한 문항(식습관이 불규칙하다)의 infit, outfit 모두 .7미만으로 나타났다. 두 문항을 제거하고 최종 한국성인에게 적합한 6요인 19문항의 비만위험측정척도를 개발하였다. The purpose of this study is development and validation of Obesity Risk Measurement Scale to Korean adults through Rasch model. To increase validity and reliability, This study accomplished pilot test(N=336) and real test(N=680). Based on the literature review and consultation of content and measurement experts, the 28-item Obesity Risk Measurement Scale was generated. The 28-item was analyzed through Exploratory Factor Analysis through SPSS program. The result was the 21-item consists of six factors(physical activity, meal habit, sneck, gluttony, heredity, psychology) constructed. Rasch measurement computer program, WINSTEPS was used to analyze the data. Model data fit was determined by Infit and Outfit statistics(≥0.70 and ≤1.30). Nineteen of the 21-item had good model-data fit with acceptable fit statistics. Overall, the four rating categories functioned well; threshold advanced with category. The two items were eliminated from the final estimation. One item was "I don`t be active and behave on negative" in factor of physical activity, the other item was "I eat irregularly" in factor of meal habit. Results provided support for using the Obesity Risk Measurement Scale to Korean adults. The scale can be used to assess the risk of obesity of individuals. This scale should be constantly used to verify discriminant validity that is distinguished people of Korean Obesity and people of normal.

녹색도시지수의 핵심지표에 관한 연구

조유정(Jo, Yoo-Jung),손세형(Sohn, Sae-Hyung),김도년(Kim, Do-Nyun) 한국도시설계학회 2013 도시설계 : 한국도시설계학회지 Vol.14 No.6

도시가 기후변화의 원인으로 지목받게 된 이유는 도시의 산업화에 있으며, 화석연료에 의존하는 도시의 산업, 교통, 건물에서 발생한 이산화탄소에 기인한다. 결국 기후변화에 대응하기 위한 핵심 과제는 도시의 탄소배출 감축이며, 지금까지 이를 실천하기 위한 수단으로써 다양한 지수가 개발되어 왔다. 그러나 기존 개발된 녹색지수는 도시가 아닌 국가를 대상으로 하고 있고 특히 선진국 중심의 지표를 사용함으로써 도시 및 지역여건을 고려하지 않은 평가로 공정성을 저해함과 동시에 전 세계 도시에 범용적으로 적용하기 힘든 한계가 있다. 따라서 본 연구는 전 세계 가능한 모든 도시에 적용할 수 있는 범용성 높은 녹색도시지수를 위한 핵심지표(Key Indicator) 도출을 목적으로 한다. 이에 적합한 지표의 성격 및 역할은 자료 확보의 용이성 및 범용성을 갖춘 지표로서의 대표성이 있어야 하며, 쉽고 단순한 용어의 사용 및 평가결과로 일반인도 이해가 가능하여 탄소저감의 중요성을 대중이 쉽고 정확하게 인지할 수 있도록 해야 한다. 이러한 기본 원칙과 도시의 탄소배출요인 관점에서 OECD 환경지표를 중심으로 기존 지표를 분석하였으며, 녹색도시 실현을 위한 핵심요소로서 1인당에너지소비량(TOE), 2차산업비중, 1인당자동차보유대수, 도시화율, 지역내총생산(GRDP) 다섯가지를 연구결과로 도출하였다. Climate change has resulted from the industrialization of the city. Especially fossil fuel-dependent industry, transportation and CO2 emission out of buildings are heavily responsible for the climate change. One of the main global issues is to identify the definition of the green city in order to respond to the climate change. The one of the key implementation methods for the establishment of a green city is to reduce CO2 emission. This study aims to draw key indicators of the index for a green city applicable for cities having different regional conditions. The appropriate indicators should be drawn from the big data on basis of generality and easiness for the data retrieval. In addition, the terminology and the evaluation result for the index should be easy and simple enough for the public to understand the importance of reducing CO2 emission. The key indicators for the index of a green city drawn from the analysis consist of TOE, 2nd industry weight, car possession per person, urbanization level and GRDP.

Development of Cellulose Hydrogel Microspheres for Lipase Immobilization

Soyeon Jo,Sae-Rom Park,Yujin Oh,Jiyeon Hong,Hyung Joo Kim,Kwang Jin Kim,Kyeong Keun Oh,이상현 한국생물공학회 2019 Biotechnology and Bioprocess Engineering Vol.24 No.1

Cellulose hydrogel microspheres were prepared by sol-gel transition using an ionic liquid-in-oil emulsion. Factors that influenced the formation of these microspheres, including the ratio of ionic liquid to oil, surfactant concentration, and stirring speed, were optimized for lipase immobilization. Using the optimized method, Candida rugosa lipase was efficiently immobilized on the microspheres by physical adsorption. As compared with the free lipase, the specific activity of the immobilized lipase was 1.4 times higher, its half-life at 45°C was 41 times longer, and it showed an enhanced stability over a wide pH range. The lipase immobilized on cellulose microspheres showed a much higher loading efficiency, immobilization yield, and specificity constant than lipase immobilized on microcrystalline cellulose or millimeter-sized hydrogel beads. To increase the reusability of cellulose microspheres as an enzyme support material, magnetic cellulose microspheres were also prepared by adding Fe3O4. The lipase immobilized on magnetic cellulose microspheres was simply recovered using a magnet and continuously reused with a minimal loss of activity.
