With the development of GPS and the popularity of mobile devices with positioning capability, collecting massive amounts of trajectory data is feasible and easy. The daily trajectories of moving objects convey a concise overview of their behaviors. Different social roles have different trajectory patterns. Therefore, we can identify users or groups based on similar trajectory patterns by mining implicit life patterns. However, most existing daily trajectories mining studies mainly focus on the spatial and temporal analysis of raw trajectory data but missing the essential semantic information or behaviors. In this paper, we propose a novel trajectory semantics calculation method to identify groups that have similar behaviors. In our model, we first propose a fast and efficient approach for stay regions extraction from daily trajectories, then generate semantic trajectories by enriching the stay regions with semantic labels. To measure the similarity between semantic trajectories, we design a semantic similarity measure model based on spatial and temporal similarity factor. Furthermore, a pruning strategy is proposed to lighten tedious calculations and comparisons. We have conducted extensive experiments on real trajectory dataset of Geolife project, and the experimental results show our proposed method is both effective and efficient.

한국에 거주하는 외국인 유학생들의 증가에도 불구하고, 이들의 일상생활에서의 정보추구행위에 관한 연구는 미진한 상황이다. 본 연구는 한국에 거주하는 외국인 유학생들의 정착단계(입국 전, 초기정착단계, 현재)에 따른 정보요구 및 정보탐색행위를 결정적사건기법(Critical Incident Technology: CIT)을 통하여 조사하였다. 한국에 거주하는 외국인 유학생들은 일상생활과 관련된 정보요구를 학교생활 또는 학업에 관련된 정보요구보다 빈번하게 보고하였으며, 과제 등 학습과 직결된 정보요구는 현재 단계에 이르러서야 보고되었다. 유학생들은 정보요구를 해결하기 위해 웹사이트, 소셜미디어, 친구 등 여러 정보원을 사용하였다. 일방향 정보원인 웹사이트에 대하여는 부정적인 경험을 토로하는 경우가 많은 반면, 소셜미디어나 친구 등의 양방향 정보원에 대한 만족도는 높았다. 국내 유학생들이 정보탐색과정에서 경험하는 가장 큰 어려움은 언어 문제인 것으로 나타났으며, 그 외에 한국의 사회시스템에 익숙하지 못해 겪는 어려움도 보고되었다. 정착단계별로 변화하는 유학생들의 정보요구와 정보탐색행위에 대한 이해를 바탕으로, 외국인 유학생들의 일상생활에서의 정보탐색행위를 향상시킬 수 있는 방안이 논의되었다.

This study examined the relations of acculturation and parenting behaviors of 279 Korean-Chinese mothers living in Yanbian Area in China to Adjustment of their eighth- and ninth-grade children. The mothers completed a questionnaire consisted of items regarding daily eating habits(food life) and language use, the acculturation scale, and the parenting scale, and their children completed the depression, self-esteem, and social competence scale. While most of mothers preferred Korean food to Chinese food, they preferred Chinese to Korean in daily language use. The mothers'ethnic identity was negatively related to depression of their children, whereas their out-group orientation was positively related to social competence of their children. In general, the relation between mothers'acculturation and adjustment of their children was not mediated by their parenting behaviors. But maternal warmth and acceptance partly mediated the relation between their out-group orientation and social competence of their children. These results imply that their acculturation tends to have direct effects on adjustment of their children.

The study analyzed the characteristics of the daily life and the living arrangements use of the elderly with literature review after the modernization period based on the daily life perspectives. The changes in the ideology, social system, and family system, which influenced the society and families, also affected the status of the elderly and their daily lives. Consequently, they had been facing conflicts, acceptance, and internal differentiations. The characteristics of the changes in the daily lives of the elderly in different periods were as follows. The contents were written from three different perspectives, phenomenological, symbolic interaction, and Marxist. During the modernization period, the family system and the hierarchy within a family had been reformed. However, the elderly were still considered as the symbolic leader and the respected figure of the family. From a phenomenological perspective, elderlies teach the next generations and influence the family's lives. On the other hand, from a perspective of symbolic interactions, spatial adjustment behaviors toward the largest room between the elderly and the next generation were detected. The actual authority was given to the next generation. However, the elderly were still treated as the symbolic authority. Yet, as the society became more industrialized, conflicts aroused about the support of the elderly. Those, who were neglected from the family, even spent their daily time at the elderly center or the community center. The daily lives from the Marxist perspectives suggested that modernization caused the young generations, who were well-educated and had financial powers, to have initiatives. The role of the elderly was reduced and they became negligible people, who spend meaningless daily lives. The interested the Third Ages is a new perspective on the elderly, who were neglected from the industrialized society. From a phenomenological perspective, the Third Ages are the generations that seek and demand for new housing.

This study explores the daily life of Korean designers in New York. We use in-depth interviews within the daily lives of participants to first reveal the time structure and meaning of everyday life. In this everyday time frame, this study reveals the content and meaning of life in New York, which is especially useful for fashion majors. Participants were 11 single Korean women around 30 years old working as designers in New York. Data was collected from Manhattan, New York, from November 2013 to February 2014 through the use of in-depth interviews and participant observation. Data collected daily life information on time usage, money, and energy that is first summarized into 229 meaning units. In the following, 55 central meanings were derived from stories common to behaviors for study participants and 19 subcategories were compressed into academic language. Finally, the generalized categories are divided into six categories of study life, work life, future life, family life, leisure life and fashion life. As a result of the first study, the daily time structure consisted of customary public time and personal repeat time. Second, the customary public time categories included the studying for 'Beginning to jump again to the best', 'Now working as a designer in New York', and future life expecting 'Future growing as a career woman'. Repeated personal time categories include family life: 'A single life of a lonely and poor gentile', leisure life: 'Healing life that is supported by abundant advanced culture', and fashion life: 'New York fashion life coexist with harmony'. Third, work was the center of everyday life for study participants versus fashion and leisure that were central to everyday life when not working.

Purpose: The purpose of this study was to investigate the influencing factors on externalized and internalized problem behaviors among high school students. Methods: The subjects for this study were 707 students in two high schools in K province. The data were collected during the period from October to November, 2014 by use of questionnaires. The instruments used were the Korean Youth Self-report, Daily Hassles Questionnaire, State-Trait Anger Expression Inventory, and Ego Resiliency Scale. The data were analyzed using SPSS. Results: Significant predictors to explain externalized problem behaviors comprised anger-out, anger-in, anger-control, relation with parents, daily stress, and religion. It was found that these factors explained 46% of externalized problem behavior. Ego resiliency, anger-in, daily stress, gender, relation with parent, and anger-out were significant predictors to explain internalized problem behaviors. It was found that these factors explained 45% of internalized problem behaviors. Conclusion: This study suggests that the influencing factors on problem behaviors differ from externalized and internalized problem behaviors. So these findings will provide the basic data to develop a program that is differentiated by problem behavior type.

Purpose: The purpose of this study is to identify the relationship between school adjustment and stress-coping styles among adolescents. Methods: This is a descriptive correlation survey using a convenience sample of 701 middle school students in Seoul, Gyeonggi, Incheon, Jeonbuk, and Gangwon province, Korea. The study's questionnaire included a scale of school adjustment and a scale of stress-coping style. The data analysis, using the SPSS 19.0 program, involved frequency, the mean and standard deviation, the t-test, ANOVA, the scheffe test, and the Pearson correlation coefficient. Results: Positive correlations were identified between positive stress-coping styles and the adjustment to school life of adolescents. The degree of school adjustment varied significantly according to the region, grade, attending private educational institutes after school or not, academic performance, daily study hours after school, and the hours students spend on gaming and Internet use a day. With regard to the behaviors to cope with stress, teenagers with a higher sense of life-satisfaction tended to show active coping behaviors, and female students were more likely to show positive or negative coping behaviors than mystic coping behaviors. Since adolescents' stress-coping styles showed connection with their adjustment to school, it is necessary to develop stress management programs to help middle school students adjust to school life. Conclusion: Based on the study's findings, it is important to develop programs which can help students adjust to school and learn how to cope with stress positively.

The purpose of this study is to evaluate dogs' sociality toward human strangers in the absence of an owner by analyzing changes in dogs' behavior during a task of making eye contact with an experimenter to obtain snacks. A total of 17 dogs were divided into groups of high sociality (HS; n = 10, 4.4 ± 3.87 years) and low-sociality (LS; n = 7, 3.71 ± 2.06 years). A comparison of the average frequency of five behavioral types-fear-appeasement behaviors (P<0.001), sociability-related behaviors (P<0.001), stress-related behaviors (P<0.05), destruction (P < 0.001), and vocalization (P < 0.001)-between the groups showed a significant difference in all five categories. Together, these results suggest that dogs with high sociality are less exposed to various stresses and have a higher ability to adapt to new environments than dogs with low sociality. This can predict dogs' adaptability to a new environment and positive outcomes in their daily life with the owner.

Purpose: This study aimed to construct and test a predictive model that explains and predicts the quality of life in older men living alone. Methods: A self-report questionnaire was used to collect data from 334 older adult men living along aged 65 years or over living in Jeollanam-do provinces. The endogenous variables were depression, self-rated health, instrumental activity of daily life, health promotion behaviors, the number of social participation activities and quality of life. Data were analyzed using the SPSS 21.0 and AMOS 21.0 programs. Results: The final model with 14 of the 8 analysed paths showed a good fit to the empirical data: χ2 = 173.26(p < .001, df = 53), normed χ2 = 3.27, GFI = .92, NFI = .90, CFI = .93, TLI = .89, RMSEA = .08 and SRMR = .06. Activities had direct effect on quality of life of older men living alone and social support had both direct and indirect effects. Meanwhile, function and socioeconomic status showed only indirect effects. The variables included in the eight significant paths explained 83.7% of variance in the prediction model. Conclusion: Instrumental activities of daily living and social support effect directly on quality of life in the older men living alone. Findings suggest that health care providers including community nurses need to provide social support as well as empowerment programs of instrumental activities of daily living and health promotion for improving quality of life of the older men living alone.
