In the future television broadcasting a flood of information from various sources will not always be welcomed by everyone. The need of accessing specific information as required is becoming a necessity. We are interested to make the life of television consumer easier by providing an intelligent television set which can adaptively proposed certain shows to the viewer based on the user historical consumed shows. The TV watching history data consists of TV program titles with their respective genres, channels, watched times and durations, etc. The method proposed is by utilizing Hidden Markov Model (HMM) to model the user preference of kind of genres the viewer will watch based on recorded genres of several weeks time. We take watching schedule from 6 PM to midnight as boundary. The range thus divided into 3 independent time band of 2 hours each resulting in 3 time bands from 6 PM to 8 PM, 8 PM to 10 PM, and lastly 10 PM to midnight. Each time band will be represented by an HMM. From each HMM we can generate a sequence of predicted genre that the user will probably watch during corresponding time-band. Our approach assumes that the user shows a consistent behavior of watching pattern in week to week basis and during the moment of watching TV. To asses the method performance experiment is conducted using real data collected from December 2002 to May 2003. Some user's data are selected and based on that predictions are made. The resulting predictions are then compared with the actual user's history. The experiment shows satisfactory result for user with middle to high consistent behavior level.

This study examined the impact of the social features (identification, interaction, information value) and technical features (visibility affordance, metavoicing affordance, social connecting affordance) in live commerce on consumers' attachment, which in turn affects consumers' continued intent to watch live commerce and intent to purchase from the platform. Consumers' attachment was represented by emotional attachment to the live shopping streamer and functional dependence on live commerce. Furthermore, this study investigated the effect of attachment on continuous watching intention and purchase intention. Using a web-based survey and consumers in their 20s and 30s (average age: 30.32) as a sample, this study collected 274 usable responses. The results showed that among the live commerce social system constructs, identification and interaction positively affected emotional attachment to the live commerce streamer. Among the live commerce technical system constructs, visibility affordance and social connecting affordance positively influenced functional dependence on live commerce. Both emotional attachment to the live streamer and functional dependence on live commerce were positively related to a continued intent to watch, which influenced the intent to purchase. This study empirically investigated live commerce based on the socio-technical systems framework and confirmed that both social and technical factors have a significant effect on consumers. This study also identified the impact of live commerce on consumers' attitudes through attachment theory. In addition, it has proved the antecedents and effect of continuous watching of live commerce on purchase behavior by focusing on continuous watching intention where less attention was paid in live commerce research.

사회적 통념상 폭력적 게임콘텐츠는 기존의 TV와 같은 수동적 시청행위보다 능동적 행위를 요구하는 게임에서 부정적 효과가 더 크다고 보고 있다. 본 연구는 폭력적 게임에 대한 시청행위와 게임행위에서 발생할 수 있는 공포, 불안, 혐오, 분노, 적대감, 우울과 같은 부정적 감정효과를 검증하기 위해 플레이테스트 실험 방법론을 통해 분석하였다. 연구 결과 폭력게임에 대한 시청행위는 혐오, 우울과 같은 내적감정이 더 강하게 나타났으며, 능동적 게임행위에서는 분노, 적대감과 같은 외적감정 상태의 부정적 감정이 강하게 나타났다. 결론적으로 두 종류의 미디어 행위는 각기 다른 성격의 부정적 감정을 경험하게 되며 따라서 폭력 게임에 대한 능동적 게임행위가 시청행위보다 특별히 부정적 감정효과가 크다고 할 수 없다는 것을 시사하고 있다.

최근 IT 기술의 비약적인 발전으로 위성 및 지상파 DMB 서비스가 본격적으로 시작되면서 운전 중 TV를 시청하거나 문자나 동영상으로 제공되는 교통정보를 시청하기 위해 차량 내 TV를 설치하는 사례가 급속하게 증가하고 있다. 그러나 운전중 TV시청은 운전중 음식섭취, 라디오 조작, 휴대폰 사용 등과 유사하게 운전자의 시지각 및 인지적 주의를 분산시켜 안전운전에 방해를 초래할 것이다. 하지만 이와 관련한 국내외의 실증적인 연구가 부족할 뿐만 아니라 운전행동에 있어서 구체적으로 어떻게 영향을 주는 지도 밝혀지지 않았다 따라서 본 연구에서는 국내 운전자들을 대상으로 운전 중 TV 시청에 대한 의식조사를 하였을 뿐만 아니라 차량시뮬레이터를 통한 실험연구를 실시하였다 특히 실험연구에서는 실험참여자들을 두 집단(즉, 운전 중 TV를 시청하는 집단 대 TV를 시청하지 않는 집단)으로 구분하여 TV시청이 운전행동에 미치는 영향을 비교 ·분석하였다. 결과를 살펴보면, 운전 중 TV를 시청하는 집단이 시청하지 않는 집단에 비해서 상대적으로 시각적 주의분포의 폭이 좁고 주행안정성이 떨어졌으며 가속 및 감속 페달 조작을 급하게 하는 것으로 나타났다. 마지막으로 본 연구의 제한점 및 함의에 대하여 논의하였다.

최근 IT 기술의 비약적인 발전으로 위성 및 지상파 DMB 서비스가 본격적으로 시작되면서 운전 중 DMB를 시청하거나 문자나 동영상으로 제공되는 교통정보를 시청하기 위해 차량 내 DMB를 설치하는 사례가 급속하게 증가하고 있다. 그러나 운전중 DMB 시청은 운전중 음식섭취, 라디오 조작, 휴대폰 사용 등과 유사하게 운전자의 시지 각 및 인지적 주의를 분산시켜 안전운전에 방해를 초래할 것이다. 하지만 이와 관련한 국내외의 실증적인 연구가 부족할 뿐만 아니라 운전행동에 있어서 구체적으로 어떻게 영향을 주는지도 밝혀지지 않았다. 따라서 본 연구에서는 국내 운전자들을 대상으로 운전 중 DMB 시청이 운전행동에 미치는 영향을 살펴보기 위하여 차량시뮬레이터를 이용한 실험연구를 실시하였다. 실험설계는 피험자내 실험설계를 하였으며 실험참여자들은 두 조건(즉, 운전 중 DMB를 시청하지 않는 조건과 DMB를 시청하는 조건) 모두에서 주행실험을 수행하였다. 연구결과, 운전 중 DMB를 시청하는 조건이 시청하지 않는 조건에 비해서 목적지에 도달하는 소요시간이 더 걸렸으며 가속 및 감속 페달을 급하게 조작하였을 뿐만 아니라 조향휠 편차가 크게 나타나 주행안전성을 떨어뜨리는 것으로 나타났다. 부가적으로, DMB 조작 조건(즉, 키패드 조건, 터치패드 조건, 리모컨 조건)에 따른 운전행동 차이도 살펴보았다. 마지막으로 본 연구의 제한점 및 함의에 대하여 논의하였다.

Objectives: This study aimed to investigate the association between how often Korean adolescents watch Mukbang and Cookbang videos and their dietary habits. Methods: Data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 was analyzed for this study. The study included 51,850 middle and high school students and assessed various aspects, including demographics, frequency of watching Mukbang and Cookbang videos per week, dietary habits, health behaviors, and mental health factors. Results: Nearly a third (29.3%) of Korean adolescents watched Mukbang and Cookbang videos one to four times a week, while 13.5% watched them more than five times weekly. Females, those with lower academic achievement, and those from lower socioeconomic backgrounds were significantly more likely to be frequent viewers (P < 0.001). Increased viewing frequency was associated with poorer dietary habits. Adolescents who watched more frequently were less likely to eat breakfast and consume fruits and milk, while their consumption of fast food, high-caffeine drinks, sugary drinks, and late-night snacks increased (P < 0.001). Higher viewing frequency correlated with increased feelings of stress, depression, and loneliness (P < 0.001). Logistic regression analysis confirmed these associations. More frequent viewers were significantly less likely to eat breakfast (odds ratio (OR), 0.63; 95% confidence interval (CI), 0.58-0.68), and more likely to consume fast food (OR, 1.85; 95% CI, 1.69-2.02), high-caffeine drinks (OR, 1.43; 95% CI, 1.30-1.56), sugary drinks (OR, 1.54; 95% CI, 1.41-1.67), and late-night snacks (OR, 1.37; 95% CI, 1.25-1.51). Conclusions: Our findings suggest that frequent exposure to Mukbang and Cookbang content is linked to unhealthy dietary habits in adolescents. Educational programs may be necessary to mitigate the potential for these videos to negatively influence dietary choices.

The purpose of this study was to investigate the differences among internet and TV home-shopping perceived risk segments in regard to clothing shopping orientations and purchase intention. The subjects used for the study were 290 female consumers aged from 20 to 40 living in Seoul. The study used factor analysis, cluster analysis, ANOVA, Duncan test, and $\chi^2-test$. The results showed that the Internet and TV home-shopping perceived risks consisted of 9 factors: Products uncertainty risk, Internet shopping mall trust risk, account-related risk, delivery risk, social risk, size risk, exchange/return risk, TV watching-related risk, and price risk. The cluster analysis showed that there were five groups segmented: Size risk/TV watching risk group, Social risk/Internet trust risk group, Return risk/TV watching low-risk group, Delivery risk/product trust group, and Product risk group. The clothing shopping orientations were classified by 5 factors: Planned shopping, pleasure shopping, sales/fashion oriented shopping, time saving shopping, and credit card preference/in-store oriented shopping. The results showed that the five segmented perceived risk groups differed in regard to clothing shopping orientations, purchase intention, and demographics. Further group differences and implications of the results were discussed.

Purpose: sexual permissiveness, sexual behaviors and the consumption of mass media in female high school students. Methods: 306 students, from three different girls' high schools in Seoul, who understood the purpose of the study, participated as subjects in the research. The research tools were the mass-media consumption scale, the sexual attitudes survey, the sexual permissiveness survey, and the sexual behaviors scale. The data were analyzed using descriptive analysis, t-test, ANOVA with SPSS/WIN. 18.0 program. Results: The subjects' daily mass media consumption was 143.7 minutes of TV watching on weekdays, while 253.9 minutes on weekends, 88.5 minutes of Internet surfing, 57.8 minutes of listening to pop music. Watching TV music programs was 68.3 minutes a week. Watching TV 'alone' was 30.7% and Internet surfing in one's 'own room' was the highest at 39.9%. The average score of sexual attitudes, sexual permissiveness, and sexual behaviors was 25.7/55, 35.4/64 and 0.7/10, respectively. Sexual attitudes and sexual permissiveness varied according to how much time they spent surfing the Internet, with whom they watched TV, and how much time they spent listening to popular music; and sexual behavior differed according to the time spent on the Internet. Conclusion: Educational programs need to be developed to help young people control their media consumption behaviors. In addition, political attention and a proper system are needed to promote a healthier and sounder pop culture through a public review system.

This study was conducted to examine the interrelations among snack preference, purchasing behavior and intake of fifth and sixth grade students in elementary schools in Gyeongnam province. Frequency of snack intake was the highest in those who reported 'once a day' (45.6%) snack habit. Longer-time television viewers also showed higher frequency of snack intake than shorter-time viewers. Thirty-three percent of students purchased snacks by themselves and the frequency of snack purchasing had a significant positive relationship with TV watching time (p < 0.01). The main reason, place and time of eating snacks were 'hunger' (79.2%), their home environment (50.9%) and 'after school hours' (89.7%). The favorite snack was 'ice cream' and, this snack habit was significantly different by gender of the child (p < 0.01) and TV watching time (p < 0.01). 'Milk and dairy products' scored highest (3.47) in snack intake frequency among longer-time TV viewers (> 2hr) compared to shorter-time TV viewers and this difference was statistically significant (p < 0.001). The snack preference score was correlated positively (r = 0.454) with the intake frequency for snack and its explanation power ($R^2$) was 20.5%. With regard to snack purchase behaviors, the scores of 'checking the expiration date' and 'comparing the price with similar products' were high (in what group?). Female students (p < 0.001) and shorter-time TV viewers (< 2hr) (p < 0.01) had a more reasonable purchasing behavior. The total score of preference was significantly higher (p < 0.05) in shorter-timeTV viewers (< 2hr). In the correlation between snack purchasing behaviors and intake frequency, attractiveness (r = 0.208, p < 0.001) and preference (r = 0.330, p < 0.001) showed significant positive correlations. The result of regression analysis, preference only was selected ($R^2$= 0.108).
