Purpose - The objective of this study is to investigate the dynamic relationships among Advertising Cost (AD), Newly Registered Users(NRU), and Buying Users(BU) of Social Network Game(SNG). SNG is getting pervasive mainly due to the rapid growth of mobile game and Social Network Service(SNS). It would be helpful for marketing researchers interested in SNG and related practitioners to understand the changes in AD, NRU, and BU with time as well as the effects on one another in mutual and dynamic way. Research Design, Data, and Methodology - Necessary data were collected from Social Network Game(SNG) company. AD, NRU, and BU are endogenous variables, but new event such as launching (event) and holidays(holiday) are exogenous dummy variables. Vector Auto regression (VAR) model is generally used to examine and capture the dynamic relationships among endogenous variables. VAR model can easily capture dynamic and endogenous relationships among time-series variables. Vector Auto regression with Exogenous variables(VARX) is a model in which exogenous variables are added to VAR. To investigate this study, VARX is applied. Result - By estimating the VARX model, the author finds that the past periods' NRU affect negatively and significantly the present AD, and past periods' BU have a positive and significant impact on the increase of AD. In addition, the author shows that the past periods' AD and BU have a positive and significant effect on the increase of NRU, and the past periods' AD affect positively and significantly BU. While the impact of AD on NRU happens after 3 or 4 days (carryover effect), that of AD on BU comes about within just 1 or 2 days (immediate effect). The effect of BU on NRU can be considered as word of mouth (WOM effect). Therefore, SNG companies can obtain not only the growth of revenue but also the increase of NRU by increasing BU. Through those results, the author can also find that there are significant interactions between endogenous variables. Conclusion - This study intends to investigate endogenous and dynamic relationships between AD, NRU, and BU. They also give managerial implications to practitioners for SNS and SNG firms. Through this study, it is found that there exist significant interactions and dynamic relationships between those three endogenous variables. The results of this study can have meaningful implications for practitioners and researchers of SNG. This research is unique in that it deals with "actual" field data and intend to find "actual" relationships among variables unlike other related existing studies which intend to investigate psychological factors affecting the intention of game usage and the intention of purchasing game items. This study is also meaningful by showing that the increase of BU can be a good strategy for "killing birds with one stone" (i.e., revenue growth and NRU increase). Although there are some limitations related with future research topics, this research contributes to the current research on SNG marketing in the above mentioned ways.

The purpose of this study is to generate a substantive theory that accounts for the social readaptation of the women who have engaged in prostitution and propose a practical program for them. We used the grounded theory developed by Strauss and Corbin(1990). Raw data were collected through the in-depth interview, documents and observation. We used constant comparative method for the data analysis. The nine women who had the exprience of prostitution have participated in this study. As a result of the data analysis, in open coding were generated 116 concepts, 29 subcategories and 12 categories, In axial coding the outcomes of a paradigm model were as follows. The causal conditions were named 'hostile environment' and 'the self endowed stigma'. The phenomenon turned out to be 'living as an anonymous being'. The contextual conditions were named 'cohesion of family', 'being pushed' and 'shrinked emotion'. The intervening conditions were presented to be 'desire of self restoration as a social being', 'reactionary reconstruction'. The action/interaction strategies turned out to be 'shifting of social status', 'neighbor alliance'. The consequences were presented to be 'psychological wayfarer' and 'tentacular living'. In selective coding we found a core category, 'repetition of leaving and returning from the life world'. Based on the phenomenon, two types of participants life attitudes were found as follows : present hesitating type, self concealing type. Following the adove results, We finally suggested the need to develope a community oriented case management model.

This study was conducted to explore initial motherhood experience of non-married mothers who decided to raise their babies. We applied Rennie's hermeneutic grounded theory for this study in which 7 non-married mothers participated. 9 hermeneutic categories which are 'decision to give birth', 'feeling of hitting bottom', 'ambivalence toward a life in stomach', 'realization of motherhood', 'motherhood anxiety', 'the bridle of social tag', 'hope of motherhood', 'encounter with new self' and 'visage of weary life' were constructed based on 145 meaning units, 34 subordinate categories. The core category that integrates motherhood experiences of participants was postulated as living with two conflicting visages of motherhood which are a cure and a poison at the same time. Motherhood experience processes were emerged in five stages which are decision to give birth, psychological frustration, realization of motherhood, confusion, and hope and discouragement of motherhood. Three types of motherhood experience were analyzed in the study which are adaptative, conflictive, and resistant. Based on the result of the study, the motherhood experience of non-married mother who decided to raise their babies are the process of emergence of new identity called mother. The non-married mothers formed their motherhood identities as they internalize socioculturally granted motherhood ideology. Moreover, the gap between socially oriented motherhood and realistic role of motherhood led to confusion. Based on this study, we suggest intervention plans to the field of social welfare practice that will support initial motherhood of non-married mothers who decided to keep their babies.

This Thesis is the study on the corresponding relations between Kierkegaard's existential stages and the forms of despair. the subjects of Kierkegaard's philosophical psychology are despair and anxiety. He studies the forms of despair in Sickness Unto Death, and anxiety in The Concept of Anxiety. He seeks to elucidate the human existence by way of the psychological inquiry on despair and anxiety. I will primarily study Kierkegaard's concept of despair in order to make out his understanding of human existence and, then, inquire into his concept of anxiety supplementarily. Until now, many studies on Kierkegaard's concept of despair have been carried out mainly focusing on his Sickness Unto Death. Of course, those studies focusing on his Sickness Unto Death are meaningful in a sense, but have a limit of abstract understanding, since Kierkegaard argues many forms of despair abstractly through the ontological form of the self which is constituted by the opposing constituents such as necessity and possibility. In order to understand his abstract explanation about despair, I think, we have to compare various modes of existence and the forms of despair which are portrayed in Either/Or and Fear and Trembling. Therefore, I will enquire into his seemingly unrelated works synthetically and elucidate his understanding on the relation of the forms of despair and the stages of existence.

In this paper I undertake to define what is mind, as a partial project of the philosophical foundation of the Mind Humanities. To this end I ask myself, where can be found the field, to which the various or whole psychological concepts and discourses generally relate, and then I identify the correct field to be the field of existential activities of human beings as being-in-the-world. When human beings as being-in-the-world live their lives, her life is built up out of the internal biological activities, the worlds of space and time, and actions. While the various scenes of individual life of man produced by a dynamic coordination of those worldly components, the basis of the mechanism of that coordination is explained by a biological model of self-sufficiency system that I developed here. On the basis of this model, I show step by step, how and through which (logical) way organisms configures their living, as it is. With respect to those steps of the life-construction of the organism, or in light of each step corresponding to each configuration, I construct different types of mind, i.e. impulsive mind, manipulative mind, meta-mind, collective consciousness/mind and finally personality, while every mind is further subdivided. Finally, I define mind, in light of its function in human life and with respect to the generalized sense of the whole processes as outlined above, as an organ which weaves (above mentioned) worldly components to Dasein, and sublimates and expands it to a better living.

It is over 12 years since the launch of Korea Train eXpress (KTX) services. Demand for the KTX has been on the increase continuously but few studies have been produced related to this phenomenon. KTX passenger demand has been constantly increasing due to influencing factors such as the expansion of network, rise of oil prices, etc. In this study, our main focus is to verify that there are other types of elements that are causing an increase in KTX demand; our approach looks at changes in social and psychological aspect that have occurred due to the reduction of travel time and cost, as well as the imposition of a five-day workweek. In other words, we considered diffusion theory in the marketing area, which affects product selection and purchasing attitudes, as a key factor that is causing passenger demand to increase. That is to say that it is hypothesized that the demand for travel on the KTX has increased due to the train's utility, which is spread by the diffusion effect Therefore, the Bass diffusion model was applied to explain the dramatic increase in KTX passenger demand. Based on this foundation, it was also discussed how certain marketing strategies that incorporate the diffusion effect should be considered variously for sustainable management of rail transportation, while considering a steady passenger demand.

Objective: This study aims to thoroughly analyze the correlation effect size between domestic violence and school violence by meta-analyzing previous studies on the correlation between school and domestic violence. Methods: For this purpose, meta-analysis was performed on the selected research material, which consists of national research data collected from various databases from 2001 to April, 2019. 16 thesis and 9 papers on the correlation between school and domestic violence were selected. A random effect model analysis based on the homogeneity examination results was performed on the selected data. Results: The results showed, just as Cohen (1977) proposed, that the correlation effect size between domestic and school violence was 0.25, which is moderate. This is a somewhat lower number than the previous studies on the same subject presented. Of the sub-categories of domestic violence, physical violence and psychological violence appeared to have a correlation effect size of 0.34 and 0.28, respectively, with physical violence showing the highest correlation effect size. Of the types of domestic violence, witnessing spouse violence and experiencing neglect appeared to have a moderate correlation size effect of 0.24. All of these results were statistically significant. Conclusion/Implications: This study utilized meta-analysis as a comprehensive and systematic method to analyze the correlation effect between domestic and school violence. The results presented may lead to discussions on the subject's social implications, limits, and propositions for future studies.

In order to examine the type of PAI profile for criminally charged juvenile offenders, the study sought to find out personality types and behavioral characteristics of 251 juvenile offenders and 173 ordinary adolescents from 2018-2020. Looking at the overall profiles of juvenile offenders and ordinary adolescents, we found differences in Infrequency(INF), Mania(MAN), Antisocial Features(ANT), Alcohol problems(ALC), Drug problems(DRG), Aggression (AGG), and Dominance(DOM) and Warmth(WRM). Based on these results, we perform clustering as factors Antisocial features(ANT), Aggression(AGG), and Dominance (DOM) with an average difference of more than five points. It was classified as Cluster 1 with a high percentage of adolescents and Cluster 2 with a high percentage of juvenile offenders, and Cluster 1 was named as a defense group because it showed a similar model to the profile of ordinary adolescents. The profile type of cluster 2 was named externalization, which can be represented as an externalization group. The results were similar to previous studies, and the profile type of juvenile offenders has higher overall clinical scale than that of ordinary adolescents, indicating behavioral problems. Continued research on juvenile offenders could lead to understanding of youth as well as juvenile offenders.

The purpose of this study was to categorize conflict resolution by exploring the conflict experiences of the elderly who participate in jobs for the elderly to create an elderly-friendly village. This study applied grounded theory, a qualitative research method, For data collection, a FGI was conducted by sampling 5 elderly job participants in ◯◯-dong, ◯◯-gu, Seoul. The data were analyzed according to the paradigm model of Strauss & Corbin(1998). As a result of the analysis, causal conditions were social, economic, psychological and physical motivations for participation and contextual conditions were economic difficulties, social disconnection, and differences in life experiences influenced the initiation of conflict. The core phenomena were conflict initiated by 'the difference between experience and role' and 'the difference in psychosocial relationship skills', and the intervention condition were the activation of interpersonal relationships through communication to resolve the conflict, social integration through the use of capabilities, It appeared as a regular social activities. The interaction strategy emerged as a strategy for resolving conflict for senior citizen jobs through education, mutual support for building trust, and successful senior-friendly village program operation. The consequences, it was found that job conflicts for the elderly were alleviated by finding one's life, activating community exchanges, increasing a sense of achievement, and growing a sense of community. In conclusion, the conflict resolution types for senior citizens were classified into educational solution type, mutual support solution type, and success experience solution type.

The purpose of this study is to identify the moderating effect of each of the three stress response (problem-centered treatment, pursuit of social support, and positive thinking) in the effect of work-family conflict between dual-earner couples on marriage satisfaction. To this end, 369 married couples (369 wives, 369 husbands) who raise children under the age of 6 were surveyed on stress coping (problem-centered, social support, and positive thinking), work-family conflicts, and marriage satisfaction. Based on the Actor-Partner Interdependence Model (APIM), the collected data verified six research models by distinguishing the moderating effects of each of the three coping strategies from the direction of Work to Family conflict and Family to Work conflict. Interaction graphs were also presented to determine the pattern of significant buffering effects. As a result, first of all, the problem-oriented strategy of the wife buffer the negative impact of the husband's WFC on the husband's own and wife's marriage satisfaction. It was also found that problem-oriented strategy that husband himself uses to buffer the negative impact of the husband's FWC on his wife's marriage satisfaction. Second, the pursuit of social support confirmed that the negative effects of the husband's WFC on the husband's marriage satisfaction were mitigated by the pursuit of social support used by his wife. Third, in the case of positive thinking, the effect of the positive thinking on the husband's WFC on the marriage satisfaction of the husband and wife was shown, and the positive response effect of the wife's FWC conflict was also shown. Finally, based on the results of this study, the discussion and implications of the study were presented.
