본 연구는 시중 유통되고 있는 새싹채소 재배용 적콜라비 종자에서 분리한 E. coli strain RC-4-D의 생장예측모델을 개발하기 위해 수행되었다. 각 온도조건(10, 15, 20, 25, $30^{\circ}C$) 별로 적콜라비 중 E. coli strain RC-4-D 밀도 변화를 조사하였고 Baranyi model을 1차 생장예측모델로 이용하였고 각 온도별로 최대생장률(${\mu}max$)과 $10^{\circ}C$를 제외한 유도기(LPD) 값을 도출하였다. E. coli strain RC-4-D의 최대생장률에 대한 2차 생장예측모델로써 suboptimal Ratkowsky square-root, suboptimal Huang square-root, suboptimal Arrhenius-type 세 종류의 모델을 비교하였다. 모델 적합성 검정 결과, suboptimal Huang square-root 모델이 정확도가 가장 높고 suboptimal Ratkowsky square-root 모델이 편차가 가장 적은 것으로 나타났다. 종합적으로, RMSE가 0.100, $A_f$가 1.255, $B_f$가 0.999인 suboptimal Ratkowsky square-root 모델이 온도의 영향을 설명하는 가장 적합한 2차 생장예측 모델인 것으로 나타났다. 본 연구에서 개발한 모델은 적콜라비 새싹채소 생산에 있어서 E. coli의 생장을 예측하고 미생물 위해성평가를 수행하는데 활용될 것으로 기대된다. This study was conducted to develop a predictive model for the growth of Escherichia coli strain RC-4-D isolated from red kohlrabi sprout seeds. We collected E. coli kinetic growth data during red kohlrabi seed sprouting under isothermal conditions (10, 15, 20, 25, and $30^{\circ}C$). Baranyi model was used as a primary order model for growth data. The maximum growth rate (${\mu}max$) and lag-phase duration (LPD) for each temperature (except for $10^{\circ}C$ LPD) were determined. Three kinds of secondary models (suboptimal Ratkowsky square-root, Huang model, and Arrhenius-type model) were compared to elucidate the influence of temperature on E. coli growth rate. The model performance measures for three secondary models showed that the suboptimal Huang square-root model was more suitable in the accuracy (1.223) and the suboptimal Ratkowsky square-root model was less in the bias (0.999), respectively. Among three secondary order model used in this study, the suboptimal Ratkowsky square-root model showed best fit for the secondary model for describing the effect of temperature. This model can be utilized to predict E. coli behavior in red kohlrabi sprout production and to conduct microbial risk assessments.

The quality of costumes on stage and the process of its design heavily relies on its production system and skill not only on the designer's imaginations or experiences. What is more important, and yet not much acknowledged by theatre personnels are the importance of costume production process itself and the participation of minds of costume builders. Traditionally the theatrical costumes were made by people who loved theatre, who would happily pay their labor and time into something which will lose its charm as soon as moved away from stage. The tradition continues down to today's theatre industry with somewhat seemingly "better" and systematic environment, but it's still within the small boundry of limited fields of theatres. Sets and other theatrical crafts has similarity in every aspects, but what makes costumes more distinctive in terms of production process is that it deals closely with live actors and the characters and as a matter of fact, costumes are what they are. Costumes are live objects and needs to be created in a same manner. While actors are constantly striving to create a live character, the process of costume making should be nothing different. As a trained professional costume designer and a trained professional costume production personnel, and moreover a teacher of new growing field in Korea feeling responsible for the young and ambitious students' future, I chose to experiment on the possibility of building a field of professional theatrical costume production system in a world's most fertile environment of clothing sources.

Background : The hospitals of modern society, like any other business entities, have to constantly strive to secure their survival from aggressive changes and competition outside. In this unstable environment, effective leadership is one of the most effective strategies for securing organization’s growth was well as stability. This study investigated types of leadership(transformational or transactional)that is dominant in medical record departments and compared it’s effects on organizational commitment and job satisfaction of their organizational members by types. Methods : A questionnaire was developed and mailed to all medical administrators working at general hospitals throughout the country expect department directors(N=450). Of these, 150 useable questionnaires were returned and analyzed by t0test, multiple regression analysis using SPSS. Results : The organizational commitment and job satisfaction were a little bit higher than ,moderate level, and that of leadership perceived by medical record administrators was also in moderate level throughout types. Significant characteristics(positively)related to organizational commitment and job satisfaction by univariate analysis were marital(married), position(middle management)and both type of leadership styles after considering all the factors related to organizational commitment and job satisfaction together by multivariate analysis. Conclusion : The average organizational commitment and job satisfaction of medical record administrators was just in moderate level. Efforts should be made to increase them by improving leadership capacity of medical record directors, primarily by using transformational leadership approach.

C-tube를 골격성 고정원으로 이용한매복된 미성숙 영구치의 교정적 치료 : 증례 보고

Skeletal anchorage is recommended as an orthodontic treatment for an impacted immature permanent tooth. Among these methods, C-tube is relatively safe because it is fixed to the cortical bone of interdental and thelower part of the root with several short miniscrews, which causes less damage to the root in patients of earlypermanent dentition. As it can be easily bent, the traction direction can be adjusted to favorable bone densitysites. However, patient cooperation is important and traction based on physiological force in order to gain rootand dentoalveolar tissue development in immature permanent teeth is required. Periodic follow-ups should bemandatory. 매복된 미성숙 영구치는 매복의 깊이와 방향이 정상 맹출로에 크게 벗어나 있지 않는다면 물리적인 원인 제거 후 자발적맹출이 가능하다. 그러나 자발적 맹출이 일어나지 않는다면 골격성 고정원을 이용하여 교정적 견인을 하게 된다. 골격성 고정원 중 하나인 C-tube는 인접 치근 사이의 피질골상에서 4~5 mm의 짧은 여러 개의 미니 스크류로 치근 하방 부위에 고정되어 안정적이고, 초기 영구치열기 환자의 치아 손상의 가능성이 적다. 구부릴 수 있는 성질 때문에 견인력의 방향 조절도 가능하다. 매복치의 반대편 악궁에 식립 후 교정용 탄성 고무링을 이용한 수직적 견인이 가능하여 매복치를 원하는 위치에 견인할 수 있다. 하지만 C-tube의 식립 및 제거 시 절개가 필요하고, 환자의 협조가 요구된다. 또한 매복치의 견인 시, 미성숙 영구치의 치근 성장과 골, 부착 치은의 형성 등을 주의 깊게 관찰하고 주변 연조직의 염증이 생기지 않도록 치태 조절과 구강 위생 관리교육이 필요하다.

니체철학에 함의된 ‘나’, ‘너’의 성인교육학적 재해석

최수연 한국성인교육학회 2019 Andragogy Today : International Journal of Adult & Vol.22 No.3

Along with the extended globalization based on neo-liberalism, the phenomena of socio-economic inequality and the exclusion of the socially disadvantaged have been intensified at home and abroad. Also from the andragogical dimension, the educational need of the meaningful relationship with others has been raised for achieving the inclusive growth and inclusive society. The purpose of the paper was to andragogically reinterpret Nietzsche’s philosophy of Self and Others as a pre-understanding for the inclusive society. The paper defined Nietzsche as a adult educator and suggested the necessity of hermeneutical approach to examine Nietzsche’s thought on inclusiveness. The paper then discussed Nietzsche’s Self-consciousness focussing of individual’s subjectivity and the existence of human being. Based on this, the paper examined Nietzsche’s difference affirmation focussing of Will to Power and perspectivism. Lastly but not least the importance of inclusive society was examined from the perspective of Nietzsche’s eternal recurrence and Amor Fati. 신자유주의에 기반한 세계화가 확대되면서 국내외적으로 사회경제적 불평등 및 사회적 약자에 대한 배제 현상이 심화되고 있다. 아울러 성인교육차원에서는 포용성장 및 포용사회를 위한 타인과의 유의미한 관계 형성 교육의 필요성이 제기되고 있다. 본 논문의 목적은 포용사회를 위한 선 이해로써 니체철학에 함의된 자아 및 타인에 대한 인식을 성인교육학적으로 재해석하는 데 있다. 이를 위해 먼저 성인교육자로서의 니체를 정의하고 니체 철학에 함의된 포용사상에 대한 해석학적 접근의 필요성을 제시하였다. 이어 니체의 인간관과 자아인식을 개인의 주체성 및 실존성을 중심으로 논의하였다. 이를 바탕으로 니체가 포용의 바탕으로 강조하는 타인과의 차이에 대한 긍정의 중요성을 힘에의 의지와 관점주의를 중심으로 고찰하였다. 마지막으로 차이와 다양성을 수용하는 포용사회의 중요성을 니체의 영원회귀 및 운명애 사상을 중심으로 논의하였다. 결론으로 니체의 자아 및 타인에 대한 철학이 포용사회를 위한 성인교육에 주는 시사점을 논의하였다.
