이 연구는 낮은 자기통제력이 스마트폰 이용상의 사이버범죄에 미치는 영향에서 그 매개과정이 어떠한지의 연구모형을 구성함에 있어 낮은 자기통제력이 스마트폰중독에 영향을 주고 아울러 스마트폰중독이 사회학습과정과 범죄기회의 증가를 가져와 사이버범죄에 영향을 미친다는 연구모형을 구성하고 검증했다. 서울시 대학생 대상의 조사자료의 분석결과 낮은 자기통제력은 스마트폰중독에 유의미한 영향력을 가졌다. 그리고 스마트 폰사용에 중독될수록 불법친구와 접촉할 가능성이 높았고, 불법태도를 학습하며, 또한 불법기회에 노출되어 사이버범죄 가능성이 높은 것으로 나타났다. 또한 낮은 자기통제력은 스마트폰중독의 매개없이도 직접적으로 학습 및 기회요인에 유의미한 영향력을 가져 불법친구와 불법태도에, 그리고 불법기회에 유의미한 영향력을 가졌고 최종 매개변인으로 사회학습 및 기회요인이 사이버범죄에 크게 영향을 미쳤다. 이러한 결과에서 처럼 낮은 자기통제력은 스마트폰중독을 통해 그리고 학습 및 기회요인을 매개로 사이버범죄에 영향을 미치는 것을 제시했다.

This study examined the influence of cognitive-emotional regulation, emotional self-disclosure and maternal psychological control on adolescent depression. The participants in this study consisted of 280 middle school students and 287 high school students in Gyung Gi Province, Korea. The results of this study were as follows. First, the high school students exhibited higher scores on depression than middle school students while there were no meaningful differences in maternal psychological control, cognitive-emotional regulation and emotional self-disclosure. Second, both middle and high school students' depression levels were positively associated with maternal psychological control and maladaptive cognitive-emotional regulation. Both middle and high school students' depression was negatively associated with emotional self-disclosure. Third, maladaptive cognitive-emotional regulation and maternal psychological control had a significant effect on both middle and high school students' depression levels, while emotional self-disclosure had a significant effect on high school students' depression only. In both age groups there was an interactive effect of maladaptive cognitive-emotional regulation and maternal psychological control on depression.

Objective: The purpose of this study was to confirm if there are gender differences in influences of parental support, control, and school life adjustment on suicidal ideation of adolescents and to examine the mediating effect of depression on the influences of independent variables on their suicidal ideation. Methods: This study comprised a total of 671 students in seventh and eighth grades in Seoul and Gyeonggi-do. The data were analyzed for frequency, average, and standard deviation, using the t-test, Pearson's correlation analysis, stepwise regression analysis, hierarchical multiple regression analysis, and the Sobel test. Results and Conclusion: First, significant differences among adolescents' gender were shown in fathers' psychological control, mothers' behavior control, and suicidal ideation. Second, in the case of male adolescents, all independent variables were found to have a full mediating effect on their suicidal ideation. Meanwhile, in the case of female adolescents, independent variables except for mothers' psychological control were found to have a full mediating effect on their suicidal ideation. Mothers' psychological control was found to have a partial mediating effect on suicidal ideation of adolescents for both genders.

A high-frequency vibration control method is proposed in this paper for Pumped Storage Power Plants (PSPPs) using Eddy Current Tuned Mass Damper (EC-TMD), based on which a new type of EC-TMD device is designed. The eddy current damper parameters are optimized by numerical simulation. On this basis, physical simulation model tests are conducted to compare and study the effect of structural performance with and without damping, different control strategies, and different arrangement positions of TMD. The test results show that EC-TMD can effectively reduce the control effect under high-frequency vibration of the plant structure, and after the additional damping device forms EC-TMD, the energy dissipation is further realized due to the intervention of eddy current damping, and the control effect is subsequently improved. The Multi-Tuned Mass Damper (MTMD) control strategy broadens the tuning band to improve the robustness of the system, and the vibration advantage is more obvious. Also, some suggestions are made for the placement of the dampers to promote their application.

The purpose of this study is to investigate the effect of neuromuscular re-education program and general intervention program. It is focused on difference between changes of experimental before and after on 20 stroke patient's motor control ability. The obtained results are as follows; In change in motor control ability, neuromuscular re-education program group about the motor control ability was a significant difference(p<.01). And traditional intervention program group, the motor control ability was a significant difference in all of items (p<.01; p<.05) but, were not a significant difference in bladder management, social interaction, problem solving and memory. And also comparison of change in motor control ability between the experimental group and control group, the between-subjects factors were a significant difference. Most of the functional items on the functional items on the functional measurement and neuromuscular function measurement are concerned with the physical autonomy of the hemiplegic patients. More in depth knowledge may be acquired about the distribution of physical and motor control patterns with respect to the degree of neurologic deficit for the enhencement of residual motor control function in hemiplegia. In conclusion, the neuromuscular re-education program was more effect then traditional intervention program in motor control ability.

Background: Workforce health is one of the primary and most challenging issues, particularly in industrialized countries. This article aims at modeling the major factors affecting accidents in the workplace, including general health, work-family conflict, effort-reward imbalance, and internal and external locus of control. Methods: A cross-sectional study was conducted in Esfahan Steel Company in Iran. A total of 450 participants were divided into two groups-control and case-and the questionnaires were distributed among them. Data were collected through a 7-part questionnaire. Finally, the results were analyzed using SPSS 22.0 and Amos software. Results: All the studied variables had a significant relationship with the accident proneness. In the case group, general health with a coefficient of -0.37, worke-family conflict with 0.10, effort-reward imbalance with 0.10, internal locus of control with -0.07, and external locus of control with 0.40 had a direct effect on occupational stress. Occupational stress also had a positive direct effect on accident proneness with a coefficient of 0.47. In addition, fitness indices of control group showed general health (-0.35), worke-family conflict (0.36), effort-reward imbalance (0.13), internal locus of control (-0.15), and external locus of control (0.12) have a direct effect on occupational stress. Besides, occupational stress with a coefficient of 0.09 had a direct effect on accident proneness. Conclusion: It can be concluded that although previous studies and the present study showed the effect of stress on accident and accident proneness, some hidden and external factors such as work-family conflict, effort-reward imbalance, and external locus of control that affect stress should also be considered. It helps industries face less occupational stress and, consequently, less occurrence rates of accidents.

In Korea, the current noise impact assessment has not yet considered the vertical noise propagation property by buildings and other obstacles. And noise control plan has been established without conducting the economic assessment for the noise control facilities. A noise map is used to calculate the noise level based on a theoretical formula or an empirical formula, and also predict the characteristics of vertical propagation by linking with a geometry data. And It is Possible to analyze cost-effect of noise control facilities by consider installation costs. In this study, we addressed the application of noise map for noise impact assessment and cost-effect analysis of noise control facilities.

In this paper, we analyze the effect of imperfect power control on the capacity of the reverse channel in CDMA cellular system with antenna arrays in the base station. For imperfect power control, we assume that the received power at the base station from the users within each cell has log-normal distribution, and we also consider the effect of imperfect power control of co-channel interferences which arise from both its own cell and outer cells. From the result of numerical analysis, we show that the degree of power control gives a great influence on the capacity of CDMA celluar system with antenna arrays, and also that antenna arrays at the base station can improve greatly the system capacity even when the power control is imperfect.
