안동현,강준선,In Su Jung,김유석 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.5

The K120 superconducting cyclotron, which is able to accelerate ions with a range of charge-to-mass ratio between 0.13 and 0.5 from 2.0 to 30 MeV /amu is now under design at Korea Institute of Radiological & Medical Sciences(KIRAMS). If the whole range of ions is to be accelerated with only one spiral inflector and central region, the initial energy, electric potential of the spiral inflector and the dee voltage with respect to the injected ions have been determined. The magnetic field at the center of the cyclotron is about 3.1 Tesla and the operating RF frequency is in the range between 24 and 48 MHz with harmonic numbers of 2 and 4. This paper presents the design parameters of the spiral inflector and the central region of the K120 superconducting cyclotron and the results of the carbon ion beam simulations.

실험연구의 아동권리 보호

안동현 한국아동권리학회 2003 아동과 권리 Vol.7 No.3

The use of human subjects in research raises difficult legal and ethical issues. Children are an especially vulnerable population needing special consideration against violation of individual rights and exposure to undue risk as research subjects. The development of guidelines and policies to protect children as participants in research is reviewed. This paper is focusing to the U.S. federal regulations that are intended to provide an ethical guidelines for research. Recently, the need for research involving children has been recognized, and so these guidelines position more moderately. In this paper, I discuss the pro and cons regarding children as research subjects. 인간을 대상으로 하거나 참여하는 실험 연구는 윤리적, 법적으로 민감한 문제이다. 아동은 오랜 동안 실험 연구에서 제대로 보호되지 못해 왔다. 하지만 아동과 같이 취약한 집단에 대해서는 보다 특별한 보호가 필요하다는 인식이 생겼고, 따라서 실험 연구에서 아동을 보호하기 위한 지침과 정책들이 발전되어 왔다. 그 가운데 가장 발전된 미국 연방 규정을 중심으로 주요 주제에 대해 논의하고, 최근에 논의되고 있는 문제점과 국내에서의 적용가능성에 대해 제안하였다.

Maggie’s Duality and James’s Ambiguity in The Golden Bowl

안동현 한국현대영미소설학회 2019 현대영미소설 Vol.26 No.3

This paper examines Henry James’s 1905 novel The Golden Bowl and how its protagonist Maggie overcomes her flaws and restores moral order. Critics were drastically split on how they view Maggie and the value of the moral order she creates. While Charlotte is inferior to Maggie in that she lacks Maggie's sense of morals and drive to fix the status quo, Maggie is not without fault. It is questionable whether Maggie's moral order is desirable, because it comes at the cost of fear and pain, and even represents destructive moral force. Admittedly, some of her unethical actions such as deception, lying, and playacting can be excused because they were necessary for her to achieve her goal. However, her hypocrisy, self-righteousness, and hate make her a problematic character. Similarly, her immature tendency to objectify other persons is also controversial. While it is true that she matures throughout the book and overcomes the materialistic mindset that views others as collectible art pieces, she nonetheless still views them as means to meet her needs. James basically approves of the process in which Maggie implements her notion of moral order. Nevertheless, in order to stay faithful to his insight on his protagonist, he has also included many factors that call that order into question.

안면 성형 및 치과교정술과 연관된 정신적 문제들

Any cosmetic surgical procedure is to changes in body image. Almost of all is positive changes in body-related cognition, behaviors, and emotions. Changes in body image resulting from cosmetic surgery is an interaction among perceptual, cognitive, emotional, and behavioral changes. The majority of individuals who undergo cosmetic plastic surgery are satisfied with the surgical outcome and positive changes in body image. But some patients are dissatisfied with the outcome, although the surgery was successful technically. Plastic surgeons often will try to ensure that the patient does not evidence known contraindications for cosmetic surgery and to evaluate toe degree to which they are likely to benefit from the requested operation. A evaluation of patients involves assessing their preoperative expectations, conducting a multimodal assessment of body image functioning, screening for psychopathology, and ensuring that full informed consent has taken place.

의과대학 학생의 정신과학 실기 평가에서 객관적 구조화 임상 시험(OSCE) 실시

안동현,이규영,박훈기,박용천,조연규,김석현 대한신경정신의학회 2001 신경정신의학 Vol.40 No.6

Objectives:The Objective Structured Clinical Examination(OSCE) has been recently introduced in various Korean medical schools to evaluate clinical competence of medical students in the psychiatry setting. This study attempts to provide basic data for the future research to improve reliability and validity in implementing OSCE in psychiatry by analyzing OSCE checklists and scores that Hanyang University Medical School has produced for the past 4 years and examining any problems related to station duplication and correlation between OSCE scores and other test scores. Methods:OSCE was conducted for senior students of Medical School of Hanyang University from 1996 through 1999. In 1996, it was given to students in a form of self checklist after a relevant video tape was shown to them. The clinical professor evaluated them using checklists after a relevant video tape was shown to them in 1997 and 1998. In 1999, the clinical professor evaluated them using further detailed checklists after interviewing standardized patients. Stations were duplicated in 2 places over 4 years. The scores were compared and analyzed based on overall scores, each question and each duplicated station. The correlation of scores of OSCE and other examinations has been also explored. Results:The OSCE scores have changed significantly every year. The scores of the questions related to diagnosis and management showed significant correlation between the OSCE and other examinations conducted in 1998 and 1999. The overall scores for each duplicated station showed significant difference between 1997 and 1998, but not between 1996 and 1999. However the analysis of questions of OSCE conducted in 1999 indicated that the scores of 9 questions demonstrated significant difference between the duplicated stations. Conclusion:It is required to formulate and distribute checklists suited to evaluate students attitudes and qualification as clinical doctors. In order to enhance reliability across stations, the assessor needs to take sufficient training prior to examination;evaluation criteria need to be clearly defined;and further study on standardized patients is required 연구목적: 최근 국내에도 의학과 학생들의 정신과 영역에서 임상 수행 능력 평가를 위해서 OSCE(Objective Structured Clinical Examination)가 여러 의과 대학에서 도입되어 시행 중이다. 본 연구는 한양대학교 의과대학에서 4년간 시행한 OSCE 성적과 문항 분석, 시험장 복제에 따른 문제점, 타 시험 성적과 상관관계를 연구하여 향후 정신과 OSCE 시행에 따른 신뢰도와 타당도 개선 연구에 기초 자료를 제시하는 것을 목적으로 한다. 방 법: 1996년부터 1999년까지 한양대학교 의과대학에서 의학과 4학년을 대상으로 OSCE를 시행하였다. 1996년 에 비디오 시청 후 자가 체크리스트로 평가하였고, 1997년과 1998년에는 비디오 시청 후에 임상교수가 체크리 스트를 이용하여 평가하였다. 1999년에는 표준화 환자와 면담 후에 임상교수가 더욱 세분화된 체크리스트를 이 용하여 평가하였다. 4년 동안 시험장 복제를 하여 2군데 고사장에서 실시하였다. 성적 결과를 전체, 문항별, 복제된 고사장별로 비교 분석하였고, 타 시험성적과 상관성을 알아보았다. 결 과: 매년 OSCE 성적이 유의한 변화를 보였고, 1998년과 1999년에 타 시험성적과 OSCE 성적의 상관관계에 서 진단 및 처치에 관련된 문항과 유의한 상관 관계를 보였다. 복제된 고사장별 전체 성적 비교는 1996년과 1999년에 유의한 차가 없었고, 1997년과 1998년에는 유의한 차가 있었다. 그러나 1999년 OSCE의 문항별 분석에서 9문항의 점수가 복제된 고사장간에 유의한 차를 보였다. 결 론: 임상의사로서 태도나 자질을 보는 문항을 적절히 개발, 배분할 필요가 있고, 복제된 고사장간 신뢰도를 높이 기 위해서 평가교수의 충분한 사전 훈련과 명확한 평가 기준의 개발이 필요하고, 표준화 환자에 대한 연구가 더욱 필요하다

고분자 키토산 표면처리에 의한 빵의 품질 및 저장성 향상효과

안동현,최정수,이현영,김진영,윤선경,박선미 한국식품영양학회 2003 韓國食品營養學會誌 Vol.16 No.4

빵의 저장성과 품질의 향상을 목적으로 천연 첨가물인 키토산을 표면 처리한 결과 다음과 같은 결과를 얻었다. 저장 중의 생균수와 곰팡이수를 측정한 결과 키토산 처리한 빵이 생균수가 적게 측정되었고, 곰팡이도 8일 동안 발생하지 않아 뛰어난 저장성을 나타냈다. 또한 키토산 표면처리한 빵의 저장 중 산화도 크게 억제된 것으로 나타났다. 저장 중 빵의 노화에 영향을 미치는 수분함량과 수분활성의 변화는 키토산 처리한 것이 안정되게 유지됨을 알 수 있었다. 키토산을 처리하여도 빵의 pH에는 큰 영향을 미치지 않았으며, 표면색은 2.0%의 농도로 처리한 경우에만 저장 중 색의 변화가 있었고 그 이하의 농도에서는 큰 변화가 없는 것으로 나타났다. 따라서 분자량 약 120 kDa의 키토산을 2.0% 미만의 농도로 빵의 표면에 처리하면 저장성이 향상되며 노화를 억제하여 저장 중 품질을 유지할 수 있을 것으로 사료된다. Coating treatment with 120 kDa of chitosan on bread was decreased growth rate of bacteria and not detected growth of any fungi during storage period. Bread with coating by 1% and 2% of 120 kDa chitosan have had the high antioxidant. Change in the water content was lawered as the higher concentration of chitosan coating on bread. water activity has a low variance untill 2% of chitosan concentration and so there result are expected on inhibition effect of retrogradation in bread during storage period. The change of pH was not detected in bread. And the color of bread have not effected on treatment with below 2% of chitosan but had a little effect by 2% of chitosan coating.
