The purpose of this study is to find out whether smartphone overdependence serves as a significant mediating effect in the relationship of anxiety and school life adjustment to prevent and reduce problems of anxiety and smartphone overdependence among university students and to seek alternatives to improve school life adjustment. For this purpose, a structural equation model analysis was conducted on male and female university students attending a four-year university located in Gwangju Metropolitan City to verify the mediated effect. As the result of the analysis, The mediating effects of smartphone overdependence were statistically significant and presented as a partial medium, showing the direct effect of anxiety directly affecting school life adjustment and the indirect effect of anxiety on school life adjustment by means of smartphone overdependence. Based on these findings, the significance of the study and its implications were discussed, and suggestions were put forward for further study.

IT시대와는 전혀 상관없어 보이는 보드게임이 의외로 뜨고 있다. 컴퓨터 없이는 좌불안석하는 현대의 젊은이들이 종이 조각을 교환하고 자그마한 주사위 등을 굴리며 즐기고 있다. 컴퓨터와의 게임에 지쳐서일까? 사람의 호흡이 그리워서일까? 하여튼 많은 사람들이 보드게임을 즐기게 되었고, 그 수요 역시 확산되고 있다. 이번 모바일 리뷰에서는 모바일에서 구현되는 특색 잇는 보드게임 2종을 소개하고자 한다. '정반합'이라고 하지 않았던가?

본 연구는 불특정 다수를 대상으로 한 범죄가 증가하면서 높아지고 있는 사회 불안을 해소하기 위해 서울시 10개 구를 선정하여 해당 구의 치안 강화를 위한 유용한 정보를 추출했다. 그리고 이를 데이터베이스화하여 다각적인 방면에서 분석하고 추가 대응 방안을 제시하였다. 서울지방경찰청의 2022년 치안 통계와 통계청의 2020년 사회조사 결과에 따르면 전체적으로 사회가 범죄에 대한 불안에 떨고 있음을 확인할 수 있었다. 안전서비스 설치와 범죄 발생 사이의 상관관계를 파악하고 범죄 발생에 미치는 요인들을 발견하여 추가적인 대응 방안을 설계한다면 우리 사회의 범죄 발생에 대한 불안을 해소할 수 있을 것으로 사료된다.

This study is to identify perceptions and response degrees of anxiety for each factor, targeting patients for CT test and analyze the relations between factors. It is to provide scientific fundamental data to reduce anxiety by improving awareness of patients about CT test by analyzing relations between variables. The subjects of this study were surveyed in self-writing type, targeting 263 patients for CT test in the department of radiology at three University hospitals from July to September, 2010. This survey was executed once by a structured self-administered survey type. The targeting patients for CT test of anxiety will investigate for affect. Anxiety by each CT test variables depending on CT test-related features showed independent variable is Expense Responsibility, Economic burden, Sufficient explain, Explain agent, Endoscope, Biopsy, Pre treatment, Previous experience, CT side effect experience, Side effect of contrast medium and dependent variable is physical, Hospital staff, Hospital environment, Socioeconomic These used statistics program SPSS (ver. 13.0). Summarizing the above results of this study, awareness of anxiety and response to it in each variable under CT test appeared significant differences in economic burdens, state anxiety, pre-treatment anxiety, exposure anxiety to radiation, and anxiety of side effect. Therefore, pre-treatment before test and pre-training programs on chemical poison of contrast medium and side effect seem to be able to release patients' anxiety level for CT test. Ways to meditate these anxiety variables and reduce degree of anxiety are needed to be researched more and updated. In addition, impact of patients' economic burdens on CT test anxiety is required to be recognized and solved in society level.

우울증은 감정을 조절하는 뇌의 기능의 변화가 생겨 부정적인 감정이 나타나는 병이다. 불안장애와 우울증은일반인구중 15%가 평생 동안 한번 이상 앓는 질환이다. 우울증환자는 일반인보다 불안한감정의 원인인 델타파가 많거나 좌측 전두엽의 알파파가 증가하고, 우측 전두엽은 베타파가 증가하는 특징을 가지고 있다. 선행연구에서는 백색잡음을 우울증환자의 증상완화에 사용하였다. 우울증 환자에게는 백색잡음보다는 유색(갈색)잡음이 치료에 더 효과적인 연구를 기반으로 하여 무음 상태, 갈색잡음, 고주파 가중치를 적용한 갈색잡음, 청감특성을 고려한 가중치를 적용한 갈색잡음을 들었을 때 의 뇌파에 대하여 살펴보았다. 그 중 갈색잡음과 청감특성을 고려한 가중치를 적용한 갈색잡음의 경우가 가장효과가 좋았다.

We present a cloth simulation technique that is very stable yet also responsive. The stability of the technique allows the use of a large fixed time step when simulating various types of fabrics and character motions. The animations generated using this technique are strikingly realistic. Wrinkles form and disappear in a quite natural way, which is the feature that most distinguishes textile fabrics from other sheet materials. Significant improvements in both the stability and realism were made possible by overcoming the post-buckling instability as well as the numerical instability. The instability caused by buckling arises from a structural instability and therefore cannot be avoided by simply employing an implicit method. Addition of a damping force may help to avoid instabilities; however, it can significantly degrade the realism of the cloth motion. In this paper, a new buckling model based on immediate buckling assumption is proposed. A cloth element is assumed to reach a stable configuration immediately once it begins to buckle. This assumption makes it possible to simulate the fabric buckling stably without introducing any fictitious damping force. Consequently, it produces highly responsive cloth motion as well as improves the stability by modeling the fabric-specific buckling property adequately.

Wiki is an online-based collaborative tool, and has been frequently used more recently as it realizes the paradigm of web 2.0 in educational context. Especially, wiki promotes collaborative knowledge building which is the major interest of this study. The purpose of this research is to investigate the relationships among academic self-efficacy, self-efficacy for group work, wiki anxiety, participation in wiki activity, and learning achievement. Fifty nine college students participated in the wiki activity, and the data from fifty three were used for the multiple regression and path analysis. The results reported that academic self-efficacy and wiki anxiety affected participation in wiki activity, and these two variables also had indirect effects on learning achievement, mediated by participation.

Before examining stress and physiological variables (immunity, inflammation), this study conducted a pilot test to provide basic data by analyzing depression and anxiety symptoms by age group for stress coping and coping methods. As a non-face-to-face method, BDI and STAI by age group (20s to 70s) and face-to-face survey were conducted concurrently and as follow-up surveys. In 20s to 60s, according to the coping method, there was a significant decrease after stress relief, and in all age groups, anxiety decreased significantly after stress relief, and in the 50s, stress coping with exercise was the lowest after stress relief. Based on the results of this study, through basic research according to psychological variables, physiological variables according to actual stress coping methods were further verified, and subjects with high stress levels were treated with long-term exercise therapy for depression and anxiety symptoms by exercise therapy. It will be necessary to additionally verify the appropriate stress coping method for each age group and subject, such as the correlation between improvement and immunity and inflammatory response.

The broadband electrostatic noise has been observed in the boundary layer region of the earth's magnetosphers. These electrostatic waves believed to be generated by drifting ion beams in the matnetotail. We have shown the numerical simulation result of ion beam acoustic instability in the magnetotail. This instability heats both background and beam ion in the boundary layer of neutral sheet observed by satellite.

본 논문은 CNN (Convolution Neural Networks)의 첫 번째 컨볼루션층(convolution layer)을 RGB-csb(RGB channel separation block)로 대체하여 입력 영상의 RGB 값을 특징 맵에 적용시켜 정확성을 제고시킬 수 있는 선행연구 결과에 추가적으로, 훈련 및 시험 영상 수에 따른 분석을 통하여 정확도 향상방법을 제안한다. 제안한 방법은 영상의 개수가 작을수록 각 학습 간의 정확도 편차가 크게 나타나는 불안정성은 있지만 기존 CNN모델에 비하여 정확도 차이가 증가함을 알 수 있다.
