As the number of Internet users has increased, the uses of social networking sites (SNSs) and online games have become universal activities across gender and ages. The extensive distribution and the usage of the Internet are beneficial to our society, but its adverse effects, such as Internet addiction, which refers to uncontrollable excessive Internet use, are becoming prevalent. Relevant social costs are also becoming troublesome. SNS and gaming addictions have negative effects on one's life, causing significant social problems. To illustrate different facets of these addictions, Problem Behavior Theory is adopted in the study. How self-esteem and perceived family environment affect SNS addiction and gaming addiction is addressed. The main subjects are Korean university students in their 20s who use SNS and play online games. The relationship between SNS addiction and gaming addiction is also addressed.

According to a recent survey, the sales amount of luxuries and imitations is getting larger. Especially young consumers in 2,30's have a strong desire to own luxuries, so I tried to build a theoretical base on the 20's consuming trend. Meanwhile, targeting university students who represent consumers in 20's, I investigated the recognition of luxuries, shopping experience, main shopping items, monthly spending money, and future purchase intention. I also investigated shopping experience of imitation, main shopping items, purchase reasons, and future purchase intention. I tried to suggest lots of academic and practical implications in marketing strategy building of luxury brand, aiming young consumers in 20's. On the social-psychological view point, young generation have relatively weak sense of control or self-efficacy. So, they are easily submerged in conspicuous consumption by the atmosphere around. As a result of empirical research, I found that Korean students recognized luxuries as excellent in quality, or the world famous brand. In particular, statistically significant gender difference was shown in the luxuries characteristics as the high-quality brand for male students and the world famous brand for female students. Most respondents have experience buying luxuries. And more monthly spending money, more experience they have. Respondents' purchased items were in order of fashion goods, clothing, watches/jewelry, cosmetics/perfume. And the statistically significant differences between gender and monthly spending money were shown. Not many respondents purchased luxuries imitations, and main purchased items were fashion goods. Most of purchase motives are price over quality and economy reason. The phenomena that the respondents of relatively high levels of monthly spending money had lots of luxuries imitations shopping experiences is interesting. Female students showed higher purchase intention for luxuries and imitations than male students. There was no statistically significant difference in grade level, but was found something interesting in monthly spending money. As monthly spending money increased, the purchase intention of luxuries increased, but the purchase intention of luxuries imitations decreased. However, non-linear trend was shown in the specific allowance level. This is replicate of the luxuries imitations purchase experience. Following studies will be needed for the exact interpretation for this. This study is an exploratory and descriptive, but can provide lots of fruitful academic and practical implications in formulating luxuries marketing strategies.

Nowadays drunken drive and other problems related to drinking have been increased in our society. Those problems, we believe, are just the outcomes of undesirable drinking life. To investigate the drinking life of youngsters aged between 20 and 30, 271 university students and workers in Chongju area were surveyed, focusing on attitude toward drinking, drinking behavior and drinking habits. The results are as follows: 1. Youngsters, regardless of their sex, have generous attitude toward drinking. 2. Youngsters usually drink to get along with their friends or fellow workers. 3. The university students drink alone more frequently than the workers do. And to drink alone occurs when they feel mental stress or face difficulties. 4. The university students and the workers do not differ in terms of average drinking frequency per month, the number of pubs they stop by per drinking occasion, and the king of liquor they take. 5. Above 80% of the car owners have experienced the drinking drive. And they tend to smoke more while drinking.

This paper examined the relationship between stress, the most potential cause among a variety of factors causing temporomandibular joint disorder, and temporomandibular joint disorder. In particular, this paper aimed to identify the temporomandibular joint disorder of those who were in their 20s, the age when temporomandibular joint disorder possibility increased. The survey was conducted by randomly selecting 120 college students who understood the purposes of this research and agreed to the survey from July 11 to 30, 2011. For the general features of the subjects, only gender showed any statistically significant difference. In the relationship between stress and habits related to temporomandibular joint disorder, the habit which the subjects had the most was "propping up of the chin", 64.4%. Five habits were observed the most frequently in the group with the highest stress. The habit of chewing on one side of the mouth showed the highest response as 81.5% in the group with high stress. Other habits showed similar results, about 60%.

Unlike previous studies that focused on the diversity of YouTube content, this study tried to identify factors affecting users' satisfaction with the YouTube recommendation system. Specifically, by adding content preference suitability and privacy concerns to the technology acceptance model, we empirically analyzed how these variables affect user's satisfaction of the YouTube AI recommendation system. For this purpose, asurvey was conducted on college students in their 20s and 30s, and the main research results are as follows. First, in the respondents of this study, playfulness and usefulness, which are major variables of the technology acceptance model, appeared as significant factors affecting the satisfaction of the YouTube AI recommendation system, whereas the effect of ease to use was not found. Second, content preference suitability was found to affect the satisfaction with AI recommendation system, but privacy concerns did not affect the satisfaction with YouTube AI recommendation system. Based on these research results, the implications of the study and the directions for future studies were suggested.

The purpose of this study is to acoustically analyze eight Korean monophthongs produced by 29 Taiwanese learners of Korean and 20 native speakers of Korean, and to compare their pronunciations in experimental phonetics. Using the first formants(F1) and the second formants(F2) of Korean monophthongs, we can estimate the tongue positions of vowels produced by participants. In order to compare them directly, we had to normalize participants' F1 and F2. The result shows that almost all vowels of the Taiwanese learners are significantly different from those of Korean native speakers in their F1 and F2 values without the /ㅏ/ vowel. In particular, when pronouncing Korean monophthongs, the Korean learners of Taiwan had a narrow area of the place of articulation compared to the Korean native speakers except for back vowels. Finally, it shows that the Korean learners in Taiwan had a narrower range of articulation and articulated the vowels towards the back a little comparing to the Korean native speakers.

This study examined the effect of the application of Theratainment physical factors on the calf blood pressure, ankle angle, and calf circumference. A research sample consisting of normal female university students in their twenties were divided into hot therapy group (n=20), cold therapy group (n=20), and compression therapy group (n=20). By referring to the previous study, 20-minute hot therapy, 15-minute cold therapy, and 30-minute compression therapy with 100mmHg intensity was applied. The therapy was applied to left-side lower limb, followed by the application on the right-side lower limb after an hour of resting time. The calf blood pressure, ankle angle, and calf circumference of each group was assessed. In the study results, hot therapy and compression therapy showed a statistically significant difference on the decrease of blood pressure and increase of ankle angle (p<.05), but cold therapy produced no statistically significant difference. None of the three groups showed a statistically significant difference on the calf circumference. Hence, hot therapy and compression therapy is recommended for reducing calf blood pressure and increasing ankle angle related to the calf. These therapies are expected to be used for solving diverse problems of lower limbs.

The purpose of this study was to survey intention to purchase home meal replacement (HMR) made with eco-friendly food ingredients as well as need for development while analyzing importance and performance of HMR made with eco-friendly ingredients for its commercialization. From September 2014 to March 2015, questionnaires were filled out by respondents. Of the 422 questionnaires that were returned, 412 were used with 10 discarded as incomplete. Regarding reasons behind purchasing HMR, the highest percentages of both males and females answered 'ready to eat'. Almost all respondents spent 'less than 10,000 won' each time they purchased HMR. Regarding place they bought HMR, a higher percentage of respondents answered 'convenience store' and 'discount retail chain store'. In terms of improvements needed for HMR, the highest percentage of males answered 'development of a variety of menus' while the highest percentage of females answered 'change in food ingredients' at 37.7%. For development of HMR made with eco-friendly ingredients, most respondents replied that there is a need for development. Regarding intention for purchasing HMR made with eco-friendly ingredients, 66.7% of males and 73.5% of females answered they have intention to buy. Important performance analysis showed a need to improve performance of 'safety of food ingredients', which was located close to the second quadrant. To improve performance for 'safety of food ingredients', safety must be ensured through use of eco-friendly ingredients, and a systematic process for managing hazardous materials that could arise during the manufacturing process has to be developed.
