With the development of broadcasting technology from analogue to interactive digital, the number of TV channels and contents provided to audience is increasing in a rapid speed. In this multi-media and multi-channel world, it is difficult to adapt to the increase of TV channel numbers and their contents merely using remote controller to search channels. Due to this reason, EPG (Electronic Program Guide) has been one of the essential services providing convenience to audience. So EPG complying with European DVB-MHP specifications, which will be also our domestic standard, is proposed in this paper. In order to provide audiences with DiTV contents they preferred, we apply collaborative filtering algorithm to recommend contents according to preference value of audience group with similar preference. And we use JavaXlet application which is based on MHP to implement this EPG, while the result can be verified by OpenMHP emulator.

Multitasking has become part of our life. Self-interruption and switching to another task become easier and more frequent. According to previous studies, however, most of the task-switching incurs a cognitive cost. This study investigated the benefit from task switching. In Study 1, participants performed two tasks were similar, and negative correlation between the number of task switching and performance were confirmed, this result is similar to previous studies. Study 2 has shown that, made a comparison of two conditions, between possible and impossible conditions in terms of task switching. Depending on switching preference, the result of task performance has differentiated and the emotion that participants had before the task has changed. Depending on participants' switching preference, there were different amount of switching cost. Moreover, for participants who preferred task switching highly than others, task switching occurred more benefit than cost.

The acculturation of ethnic minorities is an increasingly important issue. This paper explores the role of two factors which may be related to Asian Americans' development of preferences for ethnic or non-ethnic shopping: level of acculturation and susceptibility to interpersonal influence. Several prior studies have found that strength of ethnic identification (a measure of level of acculturation) accounts for differences in consumption patterns among immigrant groups. The results of this study suggest that ethnic identification is not a unidimensional construct. Instead, two construct, ethnic identification and consumer socialization are found to be relatedto the level of influence exerted by culturally consistent in-group than "American." A strong positive relationship is found between ethnic identifi.cation and ethnocentric purchasing preferences. In contrast, no significant direct relationship between level of.consumer socialization and ethnocentric preferences is found. Implications for marketers are discussed.

In this study, it was investigated if there were some differences on the preference of researchers to grey literature among seven different subjects in the field of science and technology using citation analysis. The result shows that there were some differences among researchers, depending on the subject area. It also appears that the preference of grey literature of researchers is dissimilar in journals in English and journals in Korean, regardless of the subject area. Finally, partial correlation coefficient among nine different types of material was counted with the control of languages used and subject areas included. Among nine types of cited documents, the value of partial correlation coefficient between proceedings and miscellaneous is larger than that of any other coupled comparison This means that researchers who cite articles from proceedings tend to include information from miscellaneous at the same time.

This study aimed to compare the systems of ticketing application programs of three major movie theaters, CGV, Megabox, Lotte Cinema, with each other and evaluate the usability, and find problems to figure out user experiences for more convenient mobile ticketing. Experimental subjects with experiences of using apps of the movie theaters were recruited; First, as a primary task, they reserved movie tickets with each of the movie theater apps; Second, they had in-depth interviews with questions based on the model of Creating Pleasurable Interfaces by Stephen Anderson. As a result, users preferred the composition with information in order in overall, in which ticketing process went smoothly. In particular, users were more satisfied with convenient payment applications. Therefore, as an improving way, it is required to design an interface for users to recognize at a glance and a payment system within an app, not to design separate payment system out of the app. I hope this study will help actively conduct researches to maximize the usability in a way to reserve movie tickets through smartphone apps.

The purpose of this study is to examine factors affecting the intent of re-employment of inactive registered nurses. This study presents a secondary analysis of data collected in 'Nurse Turnover On-line Survey' by Korean Nurses Association and Korea Institute for Health and Social Affairs in 2014. The analysis shows that 70.9% of inactive RNs has an intent to return to practice, and most of them preferred 'flexible working options' (47.8%) or 'fixed day shifts' (43.3%) as a work pattern. Main reasons for resigning from their last job have been found to be 'high work intensity' (18.8%) and 'difficulties of night shifts' (16.7%). Inactive married RNs who have working histories in a general hospital or a long-term care hospital or have preferences for traditional shift works showed a stronger intent to return to practice than their reference group. Our study shows that, for inactive RNs to return to practice, it is recommendable to adopt various non-traditional working patterns, to make a staffing distribution considering the labor intensity and to develop education programs designed to increase RNs' professional satisfaction.

This study was carried out to research the use of tar colors in children's favorite foods such as candies, soft drinks, chewing gums, cereals, and ice bars in order to acquire basic data on food safety. The tar colors were simultaneously analyzed by high performance liquid chromatography (HPLC). The contents of tar colors in candies, soft drinks, gums, cereals, and ice bars were maximum 74.10 mg/100 g, 5.96 mg/100 g, 35.70 mg/100 g, 20.10 mg/100 g, and 4.93 mg/100 g, respectively. In addition, every tar colors except for Indigo carmine (B2) and Fast Green FCF (G3) among permitted tar colors were used in foods and more than two kinds of tar colors were used in most cases. From the results, only types of tar colors for foods were regulated, but the amount was not regulated.

This water system consists of sand and cobble and has a shallow water (0.1~0.8 m depth) with slow currents (0.1 m/s). 0+ years old inhabits pool consist of sand and lives in a less than 0.3 m depth. I. hugowolfeldi in Jangheung population inhabits mainly pool consists of sand and cobble and lives in a shallow water (0.1~0.8 m depth) with slow currents (0.1 m/s) compared to the stream of Geogeum Island. With some different fish species, sympatric species collected at Geogeum Island and Jangheung population are 7 species in 4 family identically in the two sites.

Recentely, the military needs to apply various technologies for the improvement of teamwork. The government should take the non-face-to-face system due to the social interest of young military members. In this study we investigated collective cohesion by helping soldiers who have difficulty expressing their feelings and delivering messages while living in groups, or who are unable to adapt to group life due to psychological disorders such as relationship anxiety. We proposed the Multi-perspective Relationship Experience program as a new VR application. We showed feeling a sense of reality equivalent to the actual situation, interpersonal tension and social distance were significantly reduced, and communication, which was difficult to actually do, was naturally achieved. In addition, positive effects were confirmed on the sense of belonging and leadership among all participants. We will be effectively used in manpower management policies that improve the collective cohesion of soldiers and support the adaptability of the military environment in line with the rapidly changing social interaction method.
