Objectives: This paper examines the mediation effect of depression in the relationship between parental abuse, parental alcoholism, and suicidal ideation in university students. Methods: A survey on abusive experience from parents, parental alcoholism, depression, and suicidal ideation was conducted with 415 students from six universities. Structural equation analysis was performed using the AMOS program. Results: The result demonstrates that depression has some mediation effects between parental abuse and suicidal ideation in university students. Meanwhile, depression has an entire mediation effect between parental alcoholism and suicidal ideation. Conclusions: This study shows that the parental alcoholism by itself did not affect suicidal ideation in university students, but depression did. Experience of parental abuse is a significant risk factor which may cause suicidal ideation, and depression may cause suicidal ideation indirectly. It calls for efforts to prevent parental abuse and emphasizes the necessity of paying primary attention to the mediation effect of depression in preventing suicidal ideation.

Italian Ryegrass (IRG), which is known as high yielding and the highest quality winter annual forage crop, is grown in mid-south area in Korea. This study aims to analyze the cause-and-effect relationship between IRG yield and climate variables such as temperature and precipitation by using IRG data and climate data of Korea Weather Bureau. From path analysis of structural equation model under multivariate normality, we found that there was a weather effect on IRG yield that the winter grass IRG yield was directly affected by spring temperature and indirectly affected by spring rainfall. These results showed that IRG can be sown in early spring in the area where it is hard to prepare for winter due to low temperature. This paper can contribute to increase IRG yield by showing the cause-and-effect relationship and this study can be extended to various structural equation models for other crops.

Recently, problems regarding marital adjustment of cancer patients are recognized as serious matter of concern for it had been reported that these issues have severe negative effects on relationship stability within marriage. It is noteworthy how marital adjustment is found to be critical for the cancer patient's mental stability, healing process and chances of survival as reported in the research. Thus, the ultimate goal of this research is to contribute to improvement of the stable relationship and also to formulate the social service related strategy for marriage adjustment for married cancer patient married couples in Korea. Actor and Partner Interdependence Model was formed in order to observe how the communication of the married couple affects marital adjustment and how this has an actor effect as well as partner effect. In order to authenticate this research model, dyadic data which sample the cancer patient and the spouse as a pair. Survey was conducted as the cancer patients who had been diagnosed with cancer and their respective spouses. The survey was taken from 160 married couples which totals to 320 people all together. Results indicated the cancer patient and the spouse have a significant relationship in marital adjustment. Through this, it had been concluded that marital adjustment is not separated but co-dependent with dynamic relationship. And the mutual constructive communication had proven to have a significant positive effect on one's marital adjustment. In demand-withdrawal communication, its negative effect on the self effect was found to be significant in both the patient and the spouse to both of their marital adjustment. Mutual avoidance communication had shown to only cause significant negative effect on self effect to the patient. In verifying the partner effect, significant negative effect was caused by patient's demand-withdrawal communication in partner effect on the spouse's marital adjustment. The results of this study are discussed in term of their implications for clinical interventions for the betterment of marital adjustment among cancer patients and their spouses. The suggestions for future research are discussed also.

Automation of programming-error detection is an important part of intelligent programming language tutoring systems. In this paper, a new programming error detection approach for novice programmers is proposed by plan matching and program execution. Program execution result is used to resolve the restricted programming plan representation and to provide a confirming evidence for the plan matching differences. By checking the values of shared variable between the related plans, we can detect the cause-effect relationship between the plans. With this relationship and the test data, we can explain the program's unexpected behaviors according to the bug's cause and resulting effects.

Meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result by integrating and analyzing many quantitative research results. This study will find meaningful mediator variables for criterion variables that affect purchase and repurchase intentions in e-commerce, on the basis of the results of a meta-analysis. We reviewed a total of 114 e-commerce studies published in Korean journals between 2000 and 2014, where a cause and effect relationship is established between variables that are specified in the conceptual model of this study. In this meta-analysis, the path between trust and purchase intention showed the biggest effect size. The second biggest effect size was found in the path between commitment and purchase intention, while the smallest one was obtained with perceived. Thus, we present the theoretical and practical implications of these results and discuss the differences among these results through a comparative analysis with previous studies.

The purpose of this study is to examine whether there is a mediating effect of hopelessness the relationship between perceived stress and suicidal ideation in college students. For this study, a survey was conducted on perceived stress, suicidal ideation, and mental health, self-esteem, problem drinking, and stress among 103 college studentsin Gyeonggi do. The results of this study are as follows. It was found that COVID-19 correlated with perceived stress, hopelessness, and suicidal ideation of college students. The hopelessness completely mediated between perceived stress and suicidal thoughts of college students, which is consistent with previous studies. This study is meaningful in that it confirmed relationship between the perceived stress, hopelessness, and suicidal ideations in college students due to COVID-19, reflecting the new situation of the times. Coronavirus will worsen people's mental health disorders and cause new stress-related disorders. Therefore, mental health researchers, clinicians, and people working in trauma-related fields should find ways to reduce the incidence of coronavirus-related trauma stress and prevent its effects. It is necessary to expand the psychological vaccine program to improve the resilience of the public. Since there are individual differences in resilience, it is necessary to strengthen the psychological vaccine program for each subject considering resilience.

Since the introduction of aspirin as a therapeutic agent in 1899, there have been numerous attempts at the improvement of its therapeutic value through molecular modification. These endeavors have centered mainly around the following two approaches : (a) improvement of the potency by introduction of a suitable group or groups on the benzene ring; and (b) modification of the carboxylic acid group, which is thought to be an immediate cause of the irritant effect.

The purpose of this research is to present the major factors which determine dominant design of Smartphone OS and to verify a logical causal relationship with them and user satisfaction. To achieve this goal, OS compatibility, OS enhancement, Installed base, and network effect were presented as determinants of Smartphone OS which serves as the basis for determining dominant design and their logical causal relationship with user satisfaction was empirically analyzed. The results of the research showed that OS compatibility and OS enhancements had a positive effect on the expansion of user base. Of the two factors, OS enhancement showed that it does not only expand the user base but also acts as the cause for the fortification of the network effect. Furthermore, it was shown that OS enhancement had a direct positive effect on user satisfaction. The findings of this research are significant in its academic contribution as well as its potential for practical application by presenting the logical causal relationship in the process of determining OS dominant design an area which was previously untouched by empirical testing.

Together with the emerging of the Eco-ship, the application of large-diameter and high-efficiency propeller required more careful attention than before in the design of the shafting system. After the adoption of Environmentally Acceptable Lubricants (EAL) to the stern tube lubrication oil, a number of aft stern tube bearing accidents have been reported, and a variety of institutions have actively conducted research on the cause relationship. This study attempted to find the cause of the accident by measuring the alignment of the shafting system of a medium-sized product/chemical tanker with aft stern tube bearing damage and analyzing the reaction force of each bearing. In addition, a reasonable solution to the correction of the shaft alignment was suggested and the feasibility was reviewed. Through various measured data and analysis, the actual installation of shafting system was slightly different from the design drawing condition, but it was found that each bearing load distribution was within the allowable range. Therefore, it was confirmed that the cause of this accident was due to the dissatisfaction the misalignment slope of aft stern tube bearing rather than the effect of the bearing overload. As a solution to this cause, countermeasures such as double slope were suggested in the aft stern tube bearing, and the characteristics of EAL also seem to have an indirect effect.
