Augmented reality game has differences with traditional games in the way what it includes physical risks happened in the real world. Although accidents related to Pokemon Go are increasing, academic discussions on the issues are rare. Thus, this study explores risk types caused by the augmented reality game and examined how perception of the risks affect usage intention on the game. This study also provides the research implications through comparative analysis between youth group who generally has the tendency toward game addiction and older group. According to the results, teenagers had less usage intention when perceived financial risk increase. In case of over twenty, time risk had negative relationship with usage intention. Physical risk had no significant effect on usage intention for teenagers, but positive relationship was observed in case over twenty. These results imply the necessity of an appropriate regulation for safe game play.

The purpose of this study was to investigate the relationship between value types and life satisfaction of Korean university students. 275 students' scores for value types, positive·negative affectivity, and subjective well-being were obtained using questionnaires. Data was analysed by correlation analysis and path analysis. The results can be summarized as followings. First, the correlation between all negative affectivity and all value was not significant. Second, conformity, benevolence, self-direction·stimulation, hedonism, achievement and security value types were positively correlated with positive affectivity, whereas, conformity, benevolence, universalism and security value types were positively correlated with life satisfaction. Third, the student's higher scores of conformity, benevolence and hedonism value types induced higher level of positive affectivity, which, in turn, increased life satisfaction. The results suggested that value types can indirectly influence life satisfaction through positive affectivity.

The aim of the study was to explore the mediating effect of meaning in life on the relationship between meaning making about process of achieving long term goals and happiness. 180 college students completed the open questionnaire about personal long life goal, also rated the scales of meaning making, meaning in life and subjective well-being. The correlation analysis, hierarchical regression analysis, and sobel test were examined. The results as followed. First, meaning making, meaning in life and happiness were positive correlated. Second, the relationship between meaning making about process achieving long term goals and happiness was completely mediated by meaning in life. The finding suggested that meaning making and meaning in life can help to enhance happiness in college students. Also the results supported that meaning in life was important factor that affects subjective well-being in Koran college students. Finally, the limitations were suggested for future research.

There has been active discussions on informational view among various privacy perspectives because of Internet usage. Social science research has largely discussed determinants of information privacy concerns (IPC) and its behavioral outcomes. However, the focus of studies was limited to company's practices and existing studies have not reported consistent results. In addition, the relationship between demographic characteristics of user and IPC has not been discussed enough. In this study, we re-investigate the relationship between users' demographic characteristics and IPC with data from a large sample provided by the Korea Information Society Development Institute (KISDI). The results showed that educational background and income level have effects on IPC in line with existing studies. But the effects of gender and age had different impact on IPC compared to previous studies. This study has implications in enabling generalization of empirical findings and confirming the results of previous studies.

Objective: The purpose of this research is to develop an intergenerational ambivalence scale which can measure the intergenerational relationship between middle-aged married couples and their mothers/mother-in-law. Method: The initial items were selected by reviewing the previous research and literature. To test validity and reliability, 222 middle-aged married couples who were residing in Seoul or the Gyeonggi area were selected. Results: The results of the research are as follows: 1) the scale was the total of 26 items consisting of two sub-factors of 14 positives and 12 negatives from the analysis of content validity, construct validity, and convergent validity, 2) the reliability of Cronbach's ${\alpha}$ were from .90 to .94 which showed a high degree of internal consistency. Conclusions: The intergenerational ambivalence scale developed is expected to serve as a useful tool for those who study the intergenerational relationship and work on the ground to measure people's intergenerational dynamics.

For the almost certainly convergent series $S_n$ of independent random variables the limiting behavior of tail series ${T_n}{\equiv}S-S_{n-1}$ is reviewed. More specifically, tail series strong laws of large number and tail series weak laws of large numbers will be introduced, and their relationship will be investigated. Then, the relationship will also be extended to the case of Banach space valued random elements, by investigating the duality between the limiting behavior of the tail series of random variables and that of random elements.

Purpose: We investigated the impact of parent, teacher, and peer relationships on adolescent school life satisfaction and confirmed the mediating effects of delinquency experiences on this relationship in this study. The structural equation modeling technique was used to analyze survey data from 650 adolescents in the W area for this survey study. The following are the key findings: First, the more positive adolescents' relationships with their parents, teachers, and peers, the lower their delinquency and the greater their satisfaction with school life. The study also discovers that delinquency experiences have a mediating effect on the relationships between parents, teachers, and peers, as well as on adolescents' school life satisfaction. Based on these findings, we present convergent intervention and practice strategies for improving adolescent school life satisfaction.

This study investigates convergent influence on childbirth perception and its association with job seeking stress, depression and hopelessness among some college women. The survey was administered to 531 college women in Jeonbuk area from March 28th to April 29th, 2016. The structured self-administered questionaries were used. The childbirth perception of respondents according to general characteristics turned out to be significantly higher in following groups: that of old age, that of religion, that of school life satisfaction, that of non drinker. The childbirth perception are significantly higher in higher job seeking stress group, moderate & severe hopeless group and moderate & major depression group. The childbirth perception was positively correlated with job seeking stress, hopelessness and depression. With the analysis of covariance structure, we could confirm relationship among the four factors such as job seeking stress, hopelessness, depression and childbirth perception. Job seeking stress was more influential on the childbirth perception than hopelessness and depression. The results are expected to be useful for health education to increase the positive thinking of childbirth perception of the college women. In the following study, the analysis about additional factors of convergent influence on childbirth perception will be needed.

Multi-camera systems which integrate two or more low-cost digital cameras are adopted to reach higher ground coverage and improve the base-height ratio in low altitude remote sensing. To guarantee accurate multi-camera integration, the geometric relationship among cameras must be determined through platform calibration techniques. This paper proposed a combined two-step platform calibration method. In the first step, the static platform calibration was conducted based on the stable relative orientation constraint and convergent conditions among cameras in static environments. In the second step, a dynamic platform self-calibration approach was proposed based on not only tie points but also straight lines in order to correct the small change of the relative relationship among cameras during dynamic flight. Experiments based on the proposed two-step platform calibration method were carried out with terrestrial and aerial images from a multi-camera system combined with four consumer-grade digital cameras onboard an unmanned aerial vehicle. The experimental results have shown that the proposed platform calibration approach is able to compensate the varied relative relationship during flight, acquiring the mosaicing accuracy of virtual images smaller than 0.5pixel. The proposed approach can be extended for calibrating other low-cost multi-camera system without rigorously mechanical structure.
