Purpose: The purpose of this study was to explore the factors affecting mental health in the use of social welfare services by male elderly, and to provide basic data that are helpful for integrated mental health promotion programs suitable for each region by comparing and analyzing the Yeongnam-Honam. Results: As a result of the analysis, when comparing the two regions, annual income, age, and physical health were found to be the influencing factors among the personal characteristics of male elderly in the Yeongnam, and caring services were found to be the influencing factors of social welfare services. Among the personal characteristics of male elderly in Honam, annual income, age, and physical health were found to be the influencing factors, and caring services were found to be the influencing factors of social welfare services. Conclusion: Based on the results of the study, three implications are presented as follows. First, it suggests that mandatory checkups are required not only for the physical health of male elderly, but also for the mental health. Second, the necessity of social welfare service policies that link health and welfare is presented. Third, the necessity of specialized mental health and welfare services by region is presented.

According to technology acceptance model(TAN) which is one of the most important research models for explaining IT users' behavior, on intention of using IT is determined by usefulness and ease of use of it. However, TAM wouldn't explain the performance of using IT while it has been considered as a very good model for prediction of the intention. Many people would not be confirmed in the performance of using IT until they can control it at their will, although they think it useful and easy to use. In other words, in addition to usefulness and ease of use as in TAM, controllability is also should be a factor to determine acceptance of IT. Especially, there is a very close relationship between controllability and ease of use, both of which explain the other sides of control over the performance of using IT, so called perceived behavioral control(PBC) in social psychology. The objective of this study is to identify the relationship between ease of use and controllability, and analyse the effects of both two beliefs over performance and intention in using IT. For this purpose, we review the issues related with PBC in information systems studies as well as social psychology, Based on a review of PBC, we suggest a research model which includes the relationship between control and performance in using IT, and prove its validity empirically. Since it was introduced as qa variable for explaining volitional control for actions in theory of planned behavior(TPB), there have been confusion about concept of PBC in spite of its important role in predicting so many kinds of actions. Some studies define PBC as self-efficacy that means actor's perception of difficulty or ease of actions, while others as controllability. However, this confusion dose not imply conceptual contradiction but a double-faced feature of PBC since the performance of actions is related with both self-efficacy and controllability. In other words, these two concepts are discriminated and correlated with each other. Therefore, PBC should be considered as a composite concept consisting of self-efficacy and controllability, Use of IT has been also one of important areas for predictions by PBC. Most of them have been studied by analysis of comparison in prediction power between TAM and TPB or modification of TAM by inclusion of PBC as another belief as like usefulness and ease of use. Interestingly, unlike the other applications in social psychology, it is hard to find such confusion in the concept of PBC in the studies for use of IT. In most of studies, controllability is adapted as PBC since the concept of self-efficacy is included in ease of use explicitly. Based on these discussions, we can suggest perceived use control(PUC) which is defined as perception of control over the performance of using IT and composed of controllability and ease of use as sub-concepts. We suggest a research model explaining acceptance of IT which includes the relationships of PUC with attitude and performance of using IT. For empirical test of our research model, two user groups are selected for surveying questionnaires. In the first group, there are freshmen who take a basic course for Microsoft Excel, and the second group consists of senior students who take a course for analysis of management information by Excel. Most of measurements are adapted ones that have been validated in the other studies, while performance is real score of mid-term in each class. In result, four hypotheses related with PUC are supported statistically with very low significance level. Main contribution of this study is suggestion of PUC through theoretical review of PBC. Specifically, a hierarchical model of PUC are derived from very rigorous studies in the relationship between self-efficacy and controllability with a view of PBC in social psychology. The relationship between PUC and performance is another main contribution.

Purpose: The object of this study Is to investigate sociodemographic and clinical characteristics, psychology, self-esteem and quality of life in cancer patients on radiation therapy and to provide useful information for therapeutic approach to cancer patients on radiation therapy. Materials and Methods: The subjects were 36 patents who had been treated with radiation therapy and 20 normal people. Sociodemographic information and clinical characteristics of cancer patients on radiation therapy were investigated, and symptom checklist-90-revised, Rosenberg Self-esteem Scale for self esteem, World Health Organization Quality of Life Assessment Instrument for quality of life were administered to subjects. And Spearman's correlation analysis was used among these. Result : The tendency of somatization, depression, anxiety and hostility in cancer group were significantly higher than normal group. Self esteem and quality of life in cancer group were significantly lower than normal group. No significant difference was found in comparison of psychology, self esteem and qualify on life according to sociodemographic variables. Among clinical characteristics, in the presence of metastasis in cancer patients, the scores of anxiety, phobia and paranoid ideation were higher In patients with pain, the score of somatization was higher And in case of weight loss, the score of somatization was higher. The higher score of depression, anxiety and hostility were significantly associated with lower self-esteem. And higher score of somatization, depression, anxiety and hostility were significantly associated with lower quality of life. Conclusion: Understanding and management of psychological symptoms, such as somatization, depression, anxiety, and hostility, and pain control are necessary to improve quality of life in cancer patients on radiation therapy.

Research on subjective well-being (SWB) has flourished in recent years. As SWB determines cognitive and motivational processes, including social comparison and cognitive dissonance, it determines how consumers make decisions, including the comparison and evaluation of alternatives. Considering that the comparison and evaluation of alternatives is related to social comparison and cognitive dissonance, the influence of SWB on the comparison and evaluation of alternatives needs to be investigated. This research aims to examine the effect of SWB on the comparison and evaluation of alternatives, especially when people acquire additional information about their chosen or non-chosen alternatives, leading to a change of absolute/relative value of alternatives. The reasonable price of an alternative as evaluated by individuals is used as a measure reflecting the perceived value of an alternative. Putting all of this together, the current study intended to investigate the influence of absolute and relative value on the reasonable price of an alternative depending on SWB. Participants were randomly assigned to one of two experiment groups (deterioration of non-chosen alternative vs. improvement of non-chosen alternative). After reading consumer report ratings of alternatives shown on monitor screens, participants chose one of the alternatives, followed by the change of the consumer report ratings (deterioration of non-chosen alternative vs. improvement of non-chosen alternative). Participants evaluated the reasonable price of their chosen alternative based on the provided price of the non-chosen alternative. Two weeks after the experiment, they were asked to answer survey questionnaire on SWB measures. A regression was performed on the reasonable price with experiment groups, mean-centered SWB, and their interaction. There was a significant simple effect of groups and SWB. More importantly, these effects were qualified by the predicted interaction of groups and SWB. To interpret this interaction further, simple slope tests were performed on the price when SWB was centered at one standard deviation above (i.e., happy people) and below (i.e., unhappy people) the mean. As predicted, happy people rated the reasonable price of the chosen alternative higher in the improvement of non-chosen alternative group than in the deterioration of non-chosen alternative group. Conversely, unhappy people showed no price difference between groups. These results show that happy people pay attention to the absolute value of the alternative, whereas unhappy people give more weight to the relative value as well as to the absolute value of a chosen alternative, indicating that unhappy people are more sensitive to the negative information of a non-chosen alternative compared to happy people. The present research expanded the existing research stream on SWB by showing the influence of SWB on the consumers' evaluation of alternatives. Furthermore, this study adds to previous research on SWB and social comparison by suggesting that unhappy people tend to be more sensitive to negative social comparison information of alternatives even when a target of social comparison is not explicitly present. Moreover, these results yield some managerial implications on how to provide product information based on SWB in order to make products more attractive among the alternatives available to consumers.

This study intended to investigate the characteristics of adolescent drug user in Korea. A questionnaire on adolescent drug use was administered to 1st or 2nd grade 898 students (465 males, 433 females) from 9 senior high schools in Seoul area. The extent of current using six representative drugs such as cigarettes, alcohol, chemical substance inducing hallucination(e,g., thinner, bond etc.), psychostimulant, hypnotic and minor tranqulizer was self-reported. Also their psychological distress, self-concept and individual-related variables such as academic grade, deviant behavior, drug-using peers, the perceived availability of drugs, the degree of family discipline, and the perceived parents' attitude for drinking and smoking were surveyed. Subjects were grouped into six(male) or five(female) subgroups (nonuser, simple experiencer, one kind of drug user, two kinds of drugs user, three kinds of drugs user(male only), minor tranqulizer user) to their extent of drug use. Then ANOVA procedure performed for group comparison of their psychological distress, self-concept and individual-related variables. The results showed that the most popular drugs among adolescents in Korea were cigarettes and alcohol. Minor tranqulizer was used by about 2.8% of male and 7.41% of female subjects. In general abusers showed lower academic grade, more deviant experiences, having more drug-using peers, higher degree of psychological distress, and lower postitive self-concept than nonuser group. According to the results of discriminant analysis, hostility and deviant behavior were reliable predictive variables that distinguished abuser group from nonuser group among the associated variables in this study. These results suggest that some common factors affect drug use of Korean high school students : high school students who have many common risk factors could be abusers more easily. These findings supported risk factor theory that the extent of drug use of adolescents might be associated with general maladjustment in everyday life.

Storytelling advertising is one of the most popular ad types in marketing field. However, there has been little attention to storytelling ads in consumer and advertising research. To examine the effectiveness of different types of advertising, this study collected 9 commertial ads, which consisted of 3 advertising types(storytelling, informative, image) ${\times}$ 3 products(digital camera, coffee, health drink). We investigated the differences in emotions after ads and arousal level, as well as the advertising effectiveness among the three types of advertising. Preliminary analysis revealed that the emotions after ads could classified into two distinct emotion types, affective emotions and cognitive emotions, and we used the two emotion types as emotions after ads to simplify the results. The results indicate that the storytelling ads are more effective than the image ads, but this power of storytelling ads may not be found in the comparison with informative ads. It is also found that storytelling ads can help form a more positive attitude for males than for females, whereas image ads can have an more impact on females than males. In addition, it can be proposed that affective emotions after ads may play an important role in the effectiveness of advertising types, but the interaction effects of advertising types and gender may depend on the cognitive emotions after ads.

For scoring polygraph charts, the Prosecutors' Office of the Republic of Korea uses a consistency criterion in which an elevated signal on one physiological channel is scored as a deceptive response only if the signal is also elevated on other channels. In the current study, the effects of this scoring criterion on reliability and accuracy (validity) of polygraph scores were assessed. Polygraph tests on 26 suspects were evaluated twice by the same examiners. The examiners used the consistency criterion in the first evaluation. In the second evaluation, the examiners were prevented from using the criterion; the signals from each physiological channel were separated and randomly arranged before they were rescored by the same examiner. Reliability was assessed by the variation among the scores for each suspect. Accuracy was assessed by establishing a standard, based on a Latent Class Analysis model, using the results of polygraph tests on each of 182 additional suspects. Reliability and accuracy were both improved by the use of the consistency criterion which therefore was recommended.

Previous studies on the effect of incidental semantic priming on judgment, have focused mainly on mutually exclusive hypotheses. However, the present study explored whether incidental semantic activation affects diagnostic inference depending on the type of the hypothesis: mutually exclusive hypotheses vs compatible hypotheses. In Experiment 1, in case of mutually exclusive hypotheses, the final hypothesis was selected according to the incidental semantic priming, but there was no difference in the number of generated hypothesis in comparison with the control. However, for compatible hypotheses (i.e., both hypotheses can be true), the semantic priming affected the number of generated hypotheses, but not the selection of the final hypothesis. The same pattern of results was observed even when the cognitive load was increased. In Experiment 2, we found a boundary condition of incidental semantic activation on diagnostic inference. When cues related to each of the hypotheses were presented simultaneously, the incidental semantic effect disappeared. These results suggest that people consider all possible cues when making diagnostic inference in daily life. In light of these findings, further research on hypothesis generation/evaluation should take the type of hypothesis into account.

Purpose - This research aims to understand the different behaviors of consumers according to cognitive age. Specifically, this research is focused on pro-social behavior. Pro-social behavior is defined as behavior benefiting others, rather than behavior benefiting one's self. It often entails individual risk or cost, such as when giving resources to others, waiting in line, asking for or paying a fair price, or risking one's life in battle. Therefore, we sought to understand consumer psychology and cognitive age as a reflection of inner psychology. People frequently perceive themselves as younger or older than their chronological ages. This self-perceived or cognitive age is a subjective age perception independent of actual chronological age. The discrepancy degree between chronological and cognitive age represents how much individuals perceive themselves as younger than they are. This study examines the gap in donation intention based on cognitive age. In order to investigate cognitive age, composed of four sub-categories (feel-age, look-age, do-age, and interest-age), this study explores the differential donation intention based on cognitive age, which determines the relationship between the young age and old age. Research design, data, and methodology - Data research was conducted by gathering 216 survey samples, excluding those with unreliable answers. Data coding and cleaning were used and SPSS 19.0 software for the data analysis. The respondents were categorized into two types, younger cognitive ages and older cognitive ages. Additionally, we analyzed the moderating variables. In particular, we used cognitive age degree and congruency level (cognitive age low vs. cognitive age high) × (congruency close vs. congruency distant) between - subjects design. First, regression was done to verify the difference between chronological age and cognitive age. Second, a t-test was done to verify the difference of cognitive age level in donations. Third, ANOVA (analysis of variance) was done to verify the difference between cognitive age and congruency in donations. Last, ANOVA was done to verify the difference between cognitive age and moral judgments in donations. Result - The results show most respondents perceive themselves as younger than their chronological ages. In particular, older respondents feel they are younger than their actual age. Moreover, the result of the comparison between low degree and high degree groups of cognitive age, show high donations at the higher degree of cognitive age groups. In addition, the closer the distance to the beneficiaries, the higher the donation in high degree cognitive age groups. The higher moral judgment groups also show relatively high contributions in lower degree cognitive age groups. Conclusions - Donations belong to the category of pro-social behavior reflecting an individual's psychological state. Therefore, it is important in understanding cognitive age. This study implies that it is necessary to take into account both cognitive age and chronological age when segmenting donors. Moreover, this study confirmed that there are different factors affecting the motives behind donations. Thus, it may be utilized to create differential donation strategies.
