Objective : This study aims to investigate the relationship between negative sexual experience and psychiatric symptoms by gender and compare the effects of sexual assault and unwanted sexual experiences on psychiatric symptoms in patients with depression or anxiety disorders. Methods : A total of 204 respondents who have had negative sexual experiences of outpatients diagnosed with depression or anxiety disorders were evaluated with AUDIT, PSS, STAI, BDI, and SSI. Independent samples t-test was performed to compare the psychiatric symptom scale scores between male and female and identify the difference of the psychiatric symptom scale scores between those who have had sexual assault and those who have had only unwanted sexual experience. Results : There was no difference in psychiatric symptom scale scores except for AUDIT between male and female in 204 patients with negative sexual experience. There was also no significant difference in AUDIT, PSS, and STAI scores between those who experienced sexual assault and those who experienced only unwanted sexual experiences. BDI and SSI scores are significant higher in those who experienced sexual assault than those who experienced only unwanted sexual experiences. Conclusion : This suggests that male and female may have similar levels of psychiatric symptoms after experiencing negative sexual experiences. Psychiatric symptoms caused by sexual assault may have differences from the psychiatric symptoms caused by unwanted sexual experience. Understanding the differences in psychiatric symptoms according to the type of negative sexual experience may helpful to direct the therapeutic plans.

The high degree of academic burnout experienced during academic life indicates that job skill levels during the first year following graduation are low, and the correlation with turnover intention is high. We investigated the effects of clinical practice stress and resilience on nursing students' burnout, and searched for factors that can prevent or control burnout. We recruited a convenience sample of 202 nursing students. Academic burnout, general characteristics, clinical practice stress, and resilience were assessed via self-reported questionnaires. The mean total score of academic burnout was 44.0 points; exhaustion was the highest at 18.5 points, inefficacy was 15.9 points, and cynicism was 9.6 points. High levels of clinical practice stress affected academic burnout (β=0.194, p=0.003), while high resilience was a factor that lowered the degree of academic burnout (β=-0.449, p<0.001). Based on our results, factors affecting students' experiences of academic burnout were clinical practice stress and resilience. We therefore propose the implementation of a new curriculum aimed at increasing satisfaction with the major, reducing clinical practice stress, and increasing resilience, including an efficient peer mentoring program for clinical practice.

Purpose: The purpose of this study is to investigate the factors influencing suicidal ideation in middle school students. Methods: Suicidal Ideation Questionnaire (SIQ) results, personal characteristics, child abuse experiences, and stress were obtained from a sample of 657 middle school students from 3 conveniently selected schools in S city. Results: Suicidal ideation of participants was positively correlated with child abuse experience, stress, psychosomatic symptoms, antisocial personality and depressive tendencies, whereas sociability and self-esteem were negatively correlated with suicidal ideation. Significant factors influencing suicidal ideation included an antisocial personality tendency, stress related to the family environment, mental abuse, gender (female), depressive trend, running away from home, sociability, and stress related to academic performance. These factors explained 39.9% of the variance. Conclusion: These results suggest that earlier screening and intervention programs for depression and stress in middle school students will be helpful in reducing suicidal ideation. Further studies are needed in which other strategies that could prevent suicidal ideation in middle school students are examined.

The fashion industry has distinctive characteristics. It is important to understand the specific working environment and unique problems at fashion corporations in order enhance employee efficiency. However, studies on job stress for fashion employees remain limited. This study used qualitative research to examine major job stress factors for fashion company workers. In-depth interviews were conducted on 6 respondents who work in various departments at fashion manufacturing companies. We identified task-related factors and structural factors as the two major job stress factors. Task-related factors consisted of 4 elements (necessity of massive knowledge, overtime outside work, tight schedules, and organizational tasks); structural factors consisted of 3 elements (burden of sales outcome, formal relationships, and anxiety of salary retirement). The results indicated that respondents consistently tried to gain knowledge about the latest trends and field experiences that caused mental and physical exhaustion due to the necessity of working late. Designers and workers in the sales department were constantly evaluated by their sales results compared to other workers that caused high levels of stress. Respondents answered that building relationships was an important factor in the fashion industry and sometimes felt that building formal relationships was more important than the ability to do work.

This purpose of this study was to identify the meaning and structure of the experiences of women who were most stressed when they live and how they respond to stress when they were stressed.Six Female college students aged 29 years were interviewed for a total of three times until data was saturated and collected until no more data were collected. Interview data was processed through the analysis and interpretation process using the Giorgi phenomenological research method. As a result, 45 semantic units was derived, these were divided again into 12 subcomponents, and then divided into 3 categories. The stress situation of female college students was a way to escape from the stress that arises in situations that were difficult to overcome due to their inability to cope with, and that they were trying to take a walk or listen to music. A young women aged group, female college students becomes the center of the future family. Therefore, their emotional health will be more important than any other class. In conclusion, this study suggests the provision of a young women's tailed program that could help the female college students to experience the stress in the life task positively and to help the stress crisis as a positive experience of life.

This study examined the structural relationship between life stress perceived by university students and their gambling behaviors through their self-control and family support. For this, it conducted the questionnaire on life stress, self-control, family support and gambling behavior with 387 university students attending universities in Gwangju city and analyzed the data collected. The results of the analysis were described below. As a result of analyzing the direct effects of life stress on gambling behavior, self-control and family support, it was found that the life stress had the positive effect on gambling behavior and it meant that when the university students couldn't cope with the life stress effectively and felt frustrated, they were likely to be involved in gambling behavior to escape from their helplessness. In addition, as a result of analyzing the direct effects of life stress on self-control and family support, it was found that life stress had negative effect on self-control and family support. The more experiences of life stress they had, the lower their self-control was. As their life stress was higher, they didn't make supportive relationship network with family members. As a result of mediating effects, it was shown that self-control and family support played the partially negative roles in the relationship between life stress and gambling behavior and it suggested that as the life stress was perceived less, self-control was performed better and as family support was higher, gambling behavior was effectively reduced. These results of the research suggested that life stress could be handled actively through self-control and family support and development and distribution of the program to cope with life stress could minimize the gambling behaviors. Also the limitations of this study and necessity of further studies were discussed.

The residual stress and birefringence in injection-molded plastic parts can be divided into the flow-induced residual stress and birefringence produced in flowing stage, the thermally-induced residual stress and birefringence produced in cooling stage. However, the physics involved in the generation of the thermally-induced residual stress and birefringence still remains to be understood. Because polymer experiences viscoelastic history near the glass-transition temperature it is hard to model the entire process. Volume relaxation phenomenon was included to predict the final thermally-induced residual stress and birefringence in quenched plastic parts more accurately. The present study focused on comparing the predicted values far thermally-induced residual stress and birefringence with and without volume relaxation behavior (or free volume theory) under free and constrained quenching conditions. As a result, tile residual stress remained as a tensile stress at the center and as a compressible stress near the surface for the free quenching cases. In contract the residual stress remained as a compressible stress at the center and as a tensile stress near the surface fur the constrained quenching cases. The residual birefringence remained as minus values at the center and as plus values near the surface for the free quenching cases. Interestingly the residual birefringence showed minus values in entire zone for the constrained quenching cases. In the prediction of birefringence only the case including free volume theory showed the correct result for the distribution of birefringence in thickness direction.

In this study, we developed a semi-analytical approach for the numerical analysis of residual stress in oxide scales formed on hot-rolled steels. The oxide scale, formed during the hot rolling process, experiences complex interactions due to thermal and mechanical influences, significantly affecting the material's integrity and performance. Our research focuses on integrating various stress components such as thermal stress, growth stress, and creep behavior to predict the residual stress within the oxide layer. The semi-analytical method combines analytical expressions for each stress component with numerical integration to account for their cumulative effects. Validation through instrumented indentation tests confirms the reliability of our model, which considers thermal expansion coefficient (CTE) differences, scale growth, and creep-induced stress relaxation. Our findings indicate that thermal stress resulting from CTE differences significantly impacts the overall residual stress, with growth stress contributing a compressive component during cooling, and creep behavior playing a minor role in stress relaxation. This comprehensive approach enhances the accuracy of residual stress prediction, facilitating the optimization of material design and processing conditions for hot-rolled steel products.

In this paper, the stress analysis of the cast iron insert of spent nuclear fuel disposal canister in a deep repository at 500m underground is done for the underground pressure variation. Since the nuclear fuel disposal usually emits much heat and radiation, its careful treatment is required. And so a long term safe repository at a deep bedrock is used. Under this situation, the canister experiences some mechanical external loads such as hydrostatic pressue of underground water, swelling pressure of bentonite, sudden rock movement etc.. Hence, the canister should be designed to withstand these loads. The cast iron insert of the canister mainly supports these loads. Therefore, the stress analysis of the cast iron insert is done to determine the design variables such as the diameter versus length of canister and the number and array type of inner baskets in this paper, The linear static structural analysis is done using the finite element analysis method. And the finite element analysis code, NISA, is used for the computation.
