In recent years, human is experiencing an 'untact' era that has not been existed before. A remarkable features of an untact era is a limited or no interaction with other people and things in a daily life. In order to overcome this special situation, diverse state-of-the-art technologies like ICT technology are being used to give the effect of face-to-face and contact. In particular, Virtual Reality technology allows users to actively interact with virtual environments, objects, and other people, thereby providing effects that are as similar as possible to experience in real life. School freshmen are also experiencing various inconveniences because they are not experiencing the environment or academic management of newly admitted schools in the untact era. This research is a study and implementation of 'Virtual School Life Experience Content' which provides new students to tour campus, to utilize the school buildings facilities, to experience of academic schedules including course registration, and to participate in school events in an environment that is as close as possible to the real campus. Freshmen will be able to easily adapt to a new school through the implemented VR content.

The purpose of this study is to examine the effect of contact with the elderly in a daily life on children's ageist attitude. Acknowledging the people's tendency to report in socially appropriate ways to the explicit attitude measurement, implicit measurement is introduced, and relation with the daily contact with elderly(DCE) is analyzed. The research question are as follows: 1) Are these two attitudes explained by different factors? 2) Can DCE alleviate both children's implicit and explicit ageist attitude? 3) How do the contact with grandparent and neighboring elderly affect the children's explicit and implicit ageist attitude? Data was collected from 503 fourth to sixth grade elementary school children. Child-Age Implict Association Test is used to measure implicit ageist attitude. Multinominal logistic analysis and ordered logistic analysis was applied. Followings are the main results: First, explicit and implicit ageist attitudes are found to be related with different predictors. Second, Elderly contact seems to lighten children's ageist attitude overall. Third, the effects of grandparental contact and the neighboring elderly contact on two different ageism were different. While the effect of elderly neighbor contact is limited to the expression of ageism, grandparental contact has a influence not only on the explicit but also on the implicit ageism, even though the effect on implicit attitude is limited in extent. Forth, not the quality of contact but the quantity of it was related to implicit ageist attitude. This result contradicts conventional idea of Intergroup Contact Theory. In the further research, the predictor of implicit ageist attitude need to be throughly examined.

마찰계수는 서로 접촉하여 운동하는 두 물체간의 특성으로 간주되며 일반적으로 상대속도나 작용하중에 별로 영향을 받지 않는 것으로 알려져 있다. 화학적으로나 물리적으로 오염되지 않은 깨끗한 금속간의 마찰실험의 경우, 이 실험이 불활성 가스나 진공내에서 행해질 경우 상당히 큰 마찰저항을 경험하게 되나, 공기중에서의 실험에서는 작은 마찰저항이 기록되어 산화막이나 다른 오염물에 의해 형성된 막이 마찰저항을 감소시킨다고 보고 있다.

Increase of immigrants in Korean society means that ethnic and cultural diversity witnessed in Western immigration countries is also appearing in overall Korean society. The purpose of this study is to suggest policy directions which fit multicultural society in the future by comparing and analyzing the difference in the recognition of multiculturalism between Koreans and immigrants. As the result of empirical analysis, it turned out that there is difference in recognition between Koreans and immigrants, for which different policy directions are required. First, it was contact experience that decided Koreans' multicultural attitudes. High level of influence of contact experience means that although Koreans take multicultural society as granted, they actually have low level of contact experience with immigrants, which requires policy tools to convert actual strengthened contact experience into positive directions. Second, in the case of immigrants, the less they recognize discrimination and the more bias is fortified, the more they accept multiculturalism as a threat. This exhibits their dual sense of identity in which they recognize themselves as foreigners toward Koreans but they distinguish themselves from other foreigners. Thus, assimilation to Korean society is not deemed to be the only alternative and Korean society needs to practice genuine multiculturalism to strengthen immigrants' ethnic identity. Study also conducted in-depth discussions on the implications of above results.

This study aims to explore the cultural contact experience of the Vietnamese Marriage Immigrant's between Vietnamese and Korean culture which is based on the traditional holidays. In order to achieve the goal of this study, this study was conducted by case study method and the data collection was conducted through in - depth interviews with 7 Vietnamese marriage immigrant women. The results of the study are as follows. While Vietnamese married immigrant women have become familiar with Korean culture by experiencing Korean culture while experiencing their own culture, they are experiencing a lot of conflicts due to cultural differences between their home country and Korea. However, they were able to confirm their aggressive adaptation in their domestic and social environments through their experience of traditional Korean festivals. Based on these findings, this study proposes the following suggestions for successful immigrant marriage immigration. First, for a harmonious family life in a Vietnamese multicultural families, it is not a one-way education for married immigrant women, but a mutual culture Education should proceed. Second, marriage immigrant women expressed the feeling that they did not feel family bond and communication in the holiday place. Therefore, it is necessary to acquire the function of traditional festival that promotes the bond of community with more specific programs and events related to traditional festivals do.

Social distance can indicate cognitive and behavioral attitudes toward a social group, and is useful for investigating people situated in a socially vulnerable position. When the children from multicultural family aware negative attitudes from peer Korean children, self-confidence and social competence can be disturbed. This study intended to examine influential factors on children's social distance towards children from multicultural families including multicultural contact experience, stereotype, ethnically homogeneous nationalism, thereby providing empirical evidence on social distance regarding multicultural families and their children. The results of this study are as follows. First, when the Korean children felt closeness with a multicultural child, when the ethnicity of the foreigner resided in the neighbor is White or Black, when they contact multicultural children through the media and a multicultural education, the level of social distance was higher, while the neighbor's ethnicity is Abrab, social distance was lower. Second, there was a significant association between the higher level of Korean children's positive cognition and emotion and the lower level of social distance. Third, hierarchial regression analyses demonstrated that positive emotion and cognition decreased the level of social distance, while both closeness with a multicultural child and taking the multicultural education increased the level of social distance. Finally, based on these results, this study suggested implications for social work practice and research to better understand and reduce children's social distance towards children from multicultural families.

Purpose: The study aimed to determine data collected during tuberculosis (TB) contact investigations and to evaluate the outcomes of these investigations. Methods: We reviewed medical records for child contacts of patients with culture-positive pulmonary TB aged 19 years or older between August 2012 and July 2014. Results: A total of 116 child contacts were identified for 79 patients with culture-positive pulmonary TB. Of 116 contacts identified, 22% were incompletely screened. Of 90 contacts who completed screening, 42% had negative tuberculin skin test (TST) results, 58% had positive results, and 1% had active pulmonary TB at the time of investigation. Of 50 contacts with TB patients with a negative smear, 50% had positive TST results. Age ${\geq}5$ years (OR 8.3; 95% CI 2.3-30) and male gender (OR 3.9; 95% CI 1.5-9.9) were significantly associated with being incompletely screened. Conclusions: Improvement is needed in the process of contact investigations to ensure that contacts of patients with active pulmonary TB are identified and appropriately screened.

Purpose. The aim of this study was to evaluate the proximal contact with a dental floss compared to a celluloid strip and a metal strip in normal dental arch and investigate what the most effective method for measuring is. Materials and methods. The subjects of this study was consisted with 20 healthy adults (10 males and 10 females) who had normal dentition. A dentist with more than 5 years of clinical experience evaluated the proximal contacts using a dental floss method, a celluloid strip method, and a metal strip method. Statistical analysis were performed by the use of Mann-Whitney U test. A P-value < .05 was considered statistically significant in all analysis. In addition, in the evaluation of proximal contact using a dental floss, the measurement of proximal contact using a celluloid strip and a metal strip was compared. Results. 80 % of all proximal contact was proper. Proper proximal contact was observed at the posterior area compared to the anterior area (P < .05). And male had proper proximal contact at the anterior area, female had proper proximal contact at the posterior area (P < .05). The consistency analysis between the results of the celluloid strip and the metal strip experiment on the results obtained from the floss using the consistency scale Kappa index shows that using celluloid strip is more advantageous than using the metal strip. Conclusion. Only 80% of all proximal contact was proper. Using celluloid strips with various thickness for evaluating of proximal contact is considered to be helpful for accurate measuring of proximal contact.

People often use haptic experience as a basis for their preference decisions and value judgments, assuming that haptic experience with a product results from the properties of the products. However, research has suggested that unplanned haptic experience, which does not arise from the properties of the product itself, can also influence people's preference and value evaluation (Ackerman, Nocera, & Bargh, 2010). In this study, in order to verify (1) if such unplanned or accidental haptic experience changes user's cognitive tendency and (2) if accidental haptic experience leads to misattribution of the cause of haptic experience, two hypotheses were suggested and empirically investigated. Participants of the experiment were exposed to certain products on a display of a tablet PC and asked to decide on the maximum price they were willing to pay for each product. The products displayed on the screen were made up of either soft material or hard material. Results of the experiment revealed that accidental haptic experience had an effect on participants' value evaluation of products via altering their cognitive inclinations. Possible applicability of accidental haptic experiences that occur in various situations were discussed.
