To investigate the present states and analyze the library anxiety among academic library users, A University library users sampled systematically and surveyed. Data collected from 707 students are analyzed and compared with the previous studies. The average LAS score is 2.55 and show differences in sex, grade levels, and major areas of study. Library use instruction reduces anxiety subscale of barriers with staff. Library anxiety is also differed according to the frequency of library visit. Especially, the anxiety subscale of affective barriers is decreased according to the grade level and frequency of library visit. Based on the results, recommendations are suggested to overcome the library anxiety.

This study was examined to identify effects of compliance with preventive behavior on COVID-19 of nursing college students. From April 24 to May 6, 2020, 195 nursing students in grades 1-4 responded to an online self-report questionnaire. Collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS/WIN 23.0 program. The result showed that compliance with preventive behavior was positively correlated with knowledge and anxiety. The multiple regression revealed knowledge(β=.418, p<.001), anxiety(β=.280, p<.001), and experience of self quarantine(β=-.107, p<.05) to be significant compliance with preventive behavior. These variables accounted for 40.4% of compliance with preventive behavior. Conclusion Accurate and positive knowledge formation of COVID-19 of nursing students is necessary and the development and application of educational programs that can practice the performance of preventive actions in everyday life is necessary.

The objective of this study was to examine the effectiveness of newly developed program for the recovery and relapse prevention in patients with anxiety disorder. Twenty-four patients with anxiety disorder received Mindfulness-Based Cognitive Therapy (MBCT) session weekly for a period of overall 8 weeks-program. Changes of depression, anxiety, negative and positive automatic thought were compared before and after the program. Depression and anxiety were improved significantly after the MBCT program(Z=-1.9, p=.06, Z=-2.9, p<.001). Conclusions: MBCT may be effective at reducing negative automatic thought and relieving anxiety and depressive symptoms in patients with anxiety disorder. However, large-sample, randomized controlled trials will be needed for generalization.

In this study, the impact of Competitive Anxiety on Cognitive Appraisal and Performance Confidence among Amateur baseball players was investigated, as well as the mediating role of Cognitive Appraisal in this relationship. Furthermore, the moderating effect of Character Strengths related to positive psychology on the relationship between Competitive Anxiety and Cognitive Appraisal was explored, dividing these Character Strengths into six virtues. To conduct this research, an online survey was administered to 201 Amateur baseball players aged 19 and above. The result of this study are as follows. First, it was found that the association between Performance Confidence and Competitive Anxiety is mediated by Cognitive Appraisal. Second, Character Strengths showed a moderating effect in the relationship between Cognitive Appraisal and Competitive Anxiety. Thirdly, statistical significance was shown for the moderated mediation effects. Specifically, it was established that values like Transcendence and Justice would considerably moderate the relationship. Notably, the degree to which Cognitive Appraisal declines as a result of Competitive Anxiety was found to be mitigated by Transcendence and Justice Character Strengths. In conclusion, based on the results of this study, implications, limitations were discussed.

풍력발전기 성능은 유동의 안정성과 풍속에 의해 결정되는데, 이때 유동 불안정성은 풍력발전기의 성능뿐만 아니라 구조적 문제를 함께 유발시킨다. 본 연구에서는 풍력발전기 타워 후류에서의 불안정성을 최소화시키기 위하여 타워 단면의 기초 형상설계 연구를 수행하였다. 기존의 풍력발전기 타워 형상에 부가 구조물을 설치함으로써 Karman vortex의 생성을 지연시키고 와류 간섭현상을 줄여 풍력발전기의 안정성을 증대시키고자 하였다. 이를 위해 다양한 타워 단면 형상에 대하여 양력계수 및 항력계수를 비교 분석하였다. 그 결과 반지름의 1/2 길이의 자유류 방향 tip과 splitter plate를 후방에 설치하는 것이 후류 불안정성을 억제하는데 가장 효율적인 것으로 나타났다.

환형 전자 빔이 진행됨에 따라 표면파의 전단 유동에 의해 발생 및 진행되는 diocotron instability(다이오코트론 불안정성)를 안정시키기 위해, 나선형 자기장이 인가된 상황을 2차원 PIC 시뮬레이션을 통해 구현하고 그 효과에 대한 조사가 수행되었다. 나선형 자기장은 2차원 단면 상에서 회전하는 자기장으로 표현되었고, 이에 대해서 자기장이 회전하는 각도와 회전 주기, 회전 방향을 변수로 하여 그 효과를 나타내었다. 결과적으로, 자기장이 회전 하는 방향과 전자 빔이 회전하는 방향이 반대가 되었을 때, diocotron instability가 진정되는 효과를 얻었으며 이는 불안정성의 근원인 전단 유동을 완화시킴으로써 얻어진 결과임이 확인되었다. 이 때, 동반되는 밀도 분산 현상에 대해서도 고려가 되었고, 결론적으로 인가되는 나선형 자기장에 대하여 가장 적절한 조건에 대한 조사가 수행되었다.

Almost every children are naturally non competitive, so they have test anxiety. Because grading in paper-pencil tests is related to competition with their friends. Intense competition should not be a part of the classroom environment. This study intends to reflect current standardized tests(summative evaluations) in an elementary school mathematics(2008) and reconstructed it's problem. Teachers should provide students with rich situational problem-solving opportunities. Therefore we conclude "summative evaluation are consisted of some large problem type which contain some subproblems, or from easy(simple) problem with relation to difficult problem)".

This study was conducted to investigate the factors influencing in the infection control performance of coronavirus infection disease-19 in registered nurse. Data were collected using descriptive structured questionnaires to examine the factors of influencing in the infection control performance. General characteristics, knowledge of infection control, anxiety, fatigue, and coronavirus infection-19 (COVID-19) respiratory infection management performance were identified from structured questionnaire. Data were analyzed using independent t-test, ANOVA, correlation analysis, and multiple regression analysis were performed using the IBM SPSS 21.0 program. Anxiety and respiratory infection management performance was a negative correlation. Multiple regression analysis indicated anxiety was predicted component of performance of coronavirus infection-19 respiratory infection management. The results indicate a need to decrease degree of anxiety by developing educational programs to improve nurses' ability to manage coronavirus infection-19 respiratory infections. In addition, it is necessary to consider applying a role-play or simulation education method so that registered nurse can take care of patients with emerging infectious diseases in advance.

Animated Character는 컴퓨터와 인간 간의 상호작용을 증진시킬 수 있는 방편으로 널리 연구가 이루어지고 있다. 본 연구에서는 Animated Character의 감시가 과제 난이도에 따른 수행과 정서에 미치는 영향을 알아보고자 하였다. 본 실험에서 실험 참가자들은 통제 집단과 감시 Animated Character 조건에 무선으로 배정되어 난이도 세 수준의 글자계산 과제를 수행하였다. 또한 정서에 미치는 영향을 알아보기 위해 상태 특성 자기평가 불안척도(State-Trait Anxiety Inventory; STAI)를 사용하였다. 실험참가자들의 수행은 과제의 정답률과 반응시간을 측정을 통해 평가되었다. 실험결과 감시 Animated Character 조건은 통제 조건 보다 유의미하게 높은 불안(Anxiety)의 증가가 있었다. 또한 감시 Animated Character 조건은 높은 난이도의 글자 계산 과제에서 통제 조건 보다 유의미하게 높은 수행을 보였다. 본 연구는 Animated Character의 감시가 과제 난이도에 따라 다른 영향을 가진다는 것을 밝힘으로써 향후 감시 시스템 등에 Animated Character를 적용함에 있어 구체적인 가이드라인을 제공한다.
