AOP 를 이용한 Request Scope 기반 RBAC 모델에 관한 연구
윤동욱 ( Dong-uk Yoon ) 한국정보처리학회 2016 한국정보처리학회 학술대회논문집 Vol.23 No.1
정보 보안 기법 중 접근 제어 기법(Access Control)은 네트워크 기반 어플리케이션에 기본적인 정보 보안 틀을 제공한다. 아울러 권한 기반 접근 제어 기법(RBAC)으로 다양한 권한 요구 사항을 중족하는 네트워크 기반 어둘리케이션의 운용이 가능하다. 그러나 Session Scope 의 권한 기반 제어 기법으로 동적 페이지들에 대한 접근 제어를 설계 배포 하기는 어렵다. 관점 지향 프로그래밍(AOP)를 이용한 동적 권한 생성으로 Session Scope 의 권한과 결합, Request Scope 의 권한을 생성해 디자인 레벨에서의 유연한 접근 권한 설계 방법에 대해 제안하며, 구현 후 확인했다.

무대공포증과 연관된 프로프라놀롤 복용과 스트레스 대처방식의 관련성: 예술고등학교 음악 전공 학생들을 대상으로
윤동욱(Dong-Uk Yoon),송병아(Byeong-a Song),이형준(Hyung-Jun Lee),유은라(Eun-ra Yu) 대한스트레스학회 2021 스트레스硏究 Vol.29 No.4
본 연구는 예술고등학교 학생들의 무대공포증과 연관된 프로프라놀롤 복용과 스트레스 대처방식의 관련성을 연구하고자 하였다. 먼저 스트레스 대처방식 유형을 두 집단으로 구분한 뒤, 각 집단별 특징과 프로프라놀롤 복용 여부와 관련된 연관요인의 차이를 확인하고자 하였다. 적극적 대처군이 62.4%로 소극적 대처군인 37.6%보다 많았으며 남학생이 여학생보다 적극적 대처를 하는 비율이 유의하게 높았다. 소극적 대처군의 경우 무대공포, 완벽주의, 불안, 회피가 유의하게 높았다. 프로프라놀롤 복용군은 미복용군에 비해 연습시간이 많았으며, 적극적 대처군에서 프로프라놀롤의 복용 여부와 연습시간은 양의 상관관계였으며, 소극적 대처군에서는 프로프라놀롤의 복용 여부와 회피 반응은 음의 상관관계였다. 향후 무대공포증 극복를 위한 치료개입방안과 프로프라놀롤 오남용 관련 연구와 예방이 필요할 것이다. Background: In order to verify the effect of taking propranolol to overcome music performance anxiety in art high school students, Lazarus and Folkman’s stress coping models were applied to classify stress coping types into active and passive coping groups and determine what factors influenced whether or not propranolol was taken. Methods: Descriptive statistics analysis was conducted to identify the general characteristics of 394 art high school students. Chi-square test and independent t-test were conducted to verify the difference between music performance anxiety and related factors according to the stress coping model. Binary logistic regression analysis was performed to analyze the factors influencing whether propranolol was taken according to the stress coping model. Results: The active coping group were higher at 62.4% compared to the 37.6% of the passive coping group. Male students had a significantly higher rate of active response than females. In the case of the passive coping group, music performance anxiety, perfectionism, anxiety, and avoidance were significantly higher. The propranolol-dosing group had more practice time than the non-dosing group. The active coping group showed a positive correlation with the practice time according to whether propranolol was taken, and the passive coping group showed a negative correlation with avoidance. Conclusions: It was confirmed that the use of propranolol to overcome music performance anxiety differed according to the stress coping model. Clinical suggestions were presented for the need for cognitive behavioral therapy on intervention measures to overcome music performance anxiety.

Objectives:Patients with alcohol dependence tend to lead to an early conclusion based on insufficient data under cognitively uncertain circumstances. Such reasoning bias is called “jumping-to-conclusion.” The aim of this study is to identify the presence of “jumping-to-conclusion” and to investigate the meaningful relationship of it with impulsivity and working memory in patients with alcohol dependence. Methods:31 hospitalized patients with alcohol dependence and 38 healthy subjects were enrolled in this study. All participants were male and they completed the following tests : the beads test, emotional card test, Barratt Impulsiveness Scale(BIS), the Wisconsin Card Sorting Test(WCST). Results:Compared to healthy subjects, the patient with alcohol dependence group displayed the tendency of making an early conclusion in both the beads test and the emotional card test. The performance on the WCST of alcoholic group were significantly poorer than that of the control group. Patients with alcohol dependence scored higher than controls in the total score of the BIS and the motor, non-planning impulsiveness subscale scores. However, The scores on the beads and emotional card test did not show statistically significant relationship with those of the BIS and the WCST. Conclusion:Based on the results of the beads and emotional card test, this study confirmed the presence of “jumping-to-conclusion” bias in patients with alcohol dependence. In addition, it can be said that this bias is not significantly related to impulsivity and cognitive function damage.

Objectives:Childhood/adolescent-onset of bipolar disorder presents functional impairments on emotional, academic, and social aspects. These impairments could continue into adulthood. However, there are few studies comparing cognitive function between childhood/adolescent- and adult-onset using psychological test. This study aims to improve understanding of childhood/adolescent-onset of bipolar disorder by comparing differences in cognitive function, clinical and demographic features between the two groups. Methods:This study was conducted on 145 patients diagnosed with bipolar disorder type I, II, and other specified bipolar disorder by DSM 5 at the time of discharge from 2016 to 2019 at the Department of Psychiatry, Pusan National University Yangsan Hospital. Demographic information, clinical data, and results of psychological tests (K-WISC-IV, K-WAIS-IV) were collected and reviewed. Results:Childhood/adolescent-onset group was significantly low in total potential IQ and in language understanding than adult-onset group (p=0.008 and p=0.013). The childhood/adolescent group had significantly more psychiatric comorbidities than the adult group (p<0.001). The average number of prescribed antipsychotic agents was 1.18 (SD=±0.64) in the childhood/adolescent group, and 1.78 (SD=±0.82) in the adult group. The difference was statistically significant (p<0.001). Conclusion:Patients with childhood/adolescent-onset bipolar disorder have lower total potential IQ and language understanding comparing patients with adult-onset bipolar disorder. This highlights the importance of conducting a well-designed prospective study to find out more about the characteristics of childhood/adolescent-onset bipolar disorder.
