This study is intended to look into the effects of depression and stress on college life adjustment of ophthalmic optics students. To achieve this, a survey was empirically carried out to 142 male and female students majoring in ophthalmic optics at colleges in Gangwon-do. The findings are as follows: Depression had a significant effect on academic adjustment and social adjustment, but no significant effect on emotional adjustment and college satisfaction. Stress also had a significant effect on academic adjustment, but no significant effect on social adjustment, emotional adjustment and college satisfaction. The above results showed that depression and stress were major factors affecting academic and social adjustments, and academic adjustment, respectively. Which means that depression restricted the activities of academic adjustment and social adjustment, and did not have a close relationship with psychological mechanisms - emotional adjustment and college life satisfaction. Stress also had a significant effect on academic adjustment, but did not have a direct relationship with social adjustment, emotional adjustment and college satisfaction.

Objectives: This study aims at analyzing relationships between college life adoption, self-efficacy, and self-esteem in undergraduates majored in dental hygiene to explore the ways to prevent college dropouts and promote and support college life adaptation. Methods: This study was made with the use of a self-completion questionnaire with 200 undergraduate students, aged 19 or older, majored in dental hygiene in three colleges situated in Gyeonggi-do, from September 02 to 11, 2019. The results were analyzed using the SPSS Program Version 22.0. Results: First, the degree of college life adaptation in undergraduates majored in dental hygiene was found to be the highest, in those who were under 20 years old and first grade, decided to major in dental hygiene because of 'its aptitude and future career', and graduated from general high school and with a high economic level. Second, the degree of college life adoption was found to be the highest in the third grade in terms of social adaptation, and of the first grade was higher than the second grade. Third, as for the degree of attachment to college, it was revealed to be the highest in those decided to major in dental hygiene because of 'its aptitude and future career', and the degrees of academic adaptation, emotional adaptation, and attachment to college were found to be higher in general high school graduates than specialized high school graduates. Fourth, the factor having the most significant influence on college life adaptation in undergraduates majored in dental hygiene was found to be self-efficacy, followed by self-esteem and economic level. Conclusion: From these results, it is possible to assume that when developing programs to prevent college dropouts in undergraduates majored in dental hygiene, it should consider their high schools, school grades, and motivations to decide to major in dental hygiene. In addition, in order to take an educational approach to raise self-esteem and self-efficacy in career decision making to raise the degree of college life adaptation.

The purpose of the present study is to explore two main research questions; whether or not there is a difference in student adjustment in college according to socio-demographics characteristics, and to analyze the effects of self-esteem, self-identity, interaction anxiousness, and parent attachment on the adjustment of college students. The results were as follows: First, students' adjustments in college showed significant differences according to gender, cramming for repeating a college entrance exam, living with their parents, college major, family income, and religion. Second, the self-esteem, self-identity, interaction anxiousness, and parent attachment of college students impacted the related adjustment. Self-identity was the most important factor for predicting the adjustment in College. Therefore, this result suggests that the programs of self-identity Improvement are needed for the adjustment in college life.

Basically corrugated board is composed of three layers of different basis weight and stock composition. Warp is well-known for one of the most important problems of corrugated board production. Warp is caused by difference of hygro-expansibility of linears between top and bottom. This research was performed to evaluate the effect of paper properties on the warp of corrugated board. To evaluate warp, dynamic expansion properties of paper was tested using DPM(dynamic penetration measuring system). The effects of sizing, stock composition and wet-pressing on dynamic expansion properties were also evaluated. Commercial base papers showed different dynamic expansion property depending on stock composition and papermaking operation. Sizing treatment decreased and wet-pressing increased the amount of dynamic expansion. To reduce warp of corrugated board, management of dynamic expansion of base papers should be controlled by manipulating moisture, heat and tension, using a variety of adjustments available on the corrugator.

Within their natural habitat, crops are often subjected to drought and heat stress, which suppress crop growth and decrease crop production. Causing overaccumulation of glycinebetaine (GB) has been used to enhance the crop yield under stress. Here, we investigated the response of wheat (Triticum aestivum L.) photosynthesis to drought, heat stress and their combination with a transgenic wheat line (T6) overaccumulating GB and its wild-type (WT) Shi4185. Drought stress (DS) was imposed by controlling irrigation until the relative water content (RWC) of the flag leaves decreased to between 78 and 82%. Heat stress (HS) was applied by exposing wheat plants to $40^{\circ}C$ for 4 h. A combination of drought and heat stress was applied by subjecting the drought-stressed plants to a heat stress as above. The results indicated that all stresses decreased photosynthesis, but the combination of drought and heat stress exacerbated the negative effects on photosynthesis more than exposure to drought or heat stress alone. Drought stress decreased the transpiration rate (Tr), stomatal conductance (Gs) and intercellular $CO_2$ concentration (Ci), while heat stress increased all of these; the deprivation of water was greater under drought stress than heat stress, but heat stress decreased the antioxidant enzyme activity to a greater extent. Overaccumulated GB could alleviate the decrease of photosynthesis caused by all stresses tested. These suggest that GB induces an increase of osmotic adjustments for drought tolerance, while its improvement of the antioxidative defense system including antioxidative enzymes and antioxidants may be more important for heat tolerance.

Purpose: The purpose of this study was to examine the effects of the simulation-based cooperation program on self-efficacy, social problem-solving ability and college life adjustment of health college students. Methods: A nonequivalent control group pre-posttest design was used. Sixty-eight students were in the experimental group receiving the simulation-based cooperation program, and 68 were in the control group with no treatment. Results: There were significant increases in self-efficacy(z=-4.70, p<.001) and college life adjustment(t=2.03, p<.05) in the experimental group compared to the control group. However, there was no difference in the social problem-solving ability (z=-1.87, p=.061) between the experimental and control groups. Conclusion: The findings indicate that the simulation-based cooperation program has a significant effect on improving self-efficacy and college life adjustment in health college students. Thus the simulation-based cooperation program to promote the social problem-solving ability needs to be more developed and research related with cooperation program is further needed.

Purpose: The study aims to assess the current status of domestic public food delivery apps and analyze the process through which sellers choose between private delivery apps and public delivery apps. This involves exploring strategiesto achieve the original purpose of public food delivery apps, which is to enhance the small business owners income and promote consumer welfare by preventing the monopoly of private food delivery apps. Research design, data and methodology: the research methodology is based on a model that introduces adjustments for non-economic effects, considering the preferences of multi-homing consumers, to more realistically reflect the benefits of sellers' choices. For data analysis, real business performance data from 'Daeguro', 'Meokkaebi', and 'Somunnan Shop' were used. Results: The study revealed that if the market share of public delivery apps within a specific region increases beyond a certain level, the benefits for small-business sellers also increase. This leads to the strategic advantage of simultaneously using both delivery apps. Furthermore, the results exhibit a tendency similar to real social phenomena. Conclusions: This analysis confirmed the role of public food delivery apps in the domestic delivery app market and presents policy recommendations, including application integration and the implementation of exclusive public interest functions, to effectively fulfill this role.

Objectives : We examined quality of life, psychosocial adjustments to illness, changes in sexual functioning, and prevalence of psychiatric disorders in AIDS patients compared to patients with chronic hepatitis B virus infection (CHB). Methods : Thirty-one men with AIDS and 50 men with CHB were enrolled. The Short-Form 12-Item Health Survey (SF-12), the Psychosocial Adjustment to Illness Scale (PAIS), and the Changes in Sexual Functioning Questionnaire short form (CSFQ-14) were administered. Results on these assessments were compared between the 31 AIDS patients and 50 CHB patients. The Structured Clinical Interview for DSMIV (SCID) was administered to determine the psychiatric diagnosis only for the AIDS patients. Results : The Physical Component Summary score (PCS) was lower in AIDS patients than in CHB patients (p<0.001). In the section examining sexual relationships, AIDS patients exhibited a lower level of adjustment (p<0.05) and had more changes in sexual function (p<0.05) than did CHB patients. Administration of the SCID to AIDS patients indicated that the lifetime prevalence of any psychiatric disorder was 56.7% ; 43.3% for mood disorders, 33.3% for alcohol use disorders, 26.7% for anxiety disorders, and 20% for adjustment disorder. Patients who had experienced any psychiatric disorder had more severe psychosocial distress (p=0.004) and evidenced a lower level of overall psychosocial adjustment (p=0.030) than patients who had not. Conclusion : We showed that AIDS patients have a high prevalence of psychiatric disorders, and that AIDS patients with psychiatric disorders were particularly low in levels of psychosocial adjustment. Thus, careful attention should be given to psychiatric aspects of AIDS patients emphasizing the early diagnosis and treatment of psychiatric disorders.

This paper uses the Panzar Rosse model to investigate the competitive conditions in the Korean life insurance companies over the period of 1999 2012. We break down the entire sample period into four distinctive groups and analyze the competitiveness of each period. The results indicate that for the pre-introduction of Bancassurance period, the H-statistic is -1.3984 and the life insurance market is found to be in monopoly or cartel. However, for the post-introduction of Bancassurance period, the H-statistic is 0.9107 and the life insurance market appears to be in monopolistic competition. The results from the introduction of retirement pension system are very similar to those of the introduction of Bancassurance. Overall, the findings indicate that the Korean life insurance market is in long-run equilibrium before the new system introduction, but make adjustments to the new equilibrium.
