In the age of digital culture, TV broadcasting is exercising more influence as a information and communication medium compared to past. With the appearance of satellite broadcasting service in 2002, the broadcasting environment became a diversified field of local TV, cable TV, satellite, internet, etc. and created the time of multi-media and multi-channel. This ongoing change of broadcasting environment made the passive audience of the past, active image makers and new accepters, participants and users of communications, who know how to choose and use media as the active centerpiece, The active acceptor as the centerpiece of channel selections has become the center of the broadcasting, whereby they pick up and enjoy their favorite TV programs and came to remember the list of their favorite channels and zap them finally. In this point of spotting their favorite channels and improving the degree of recognition for the channels, the development of the noticeable brand for a particular program has made a great contribution. The aim of this study, therefore, is to recognize the factors, which are important in the habits of watching TV and to develop professional brands for TV broadcasting programs. The range of the survey for this study was home news programs and broadcasting stations abroad, which were on air from March to May in 2004. The focus of the survey was universal and professional news programs. Through this study, it was ascertained that, in the case of news, developing a brand for an anchor as well as for a professional brand of TV program could be an important element.

According as base of digital hologram has been magnified, discussion of compression technology is expected as a international standard which defines the compression technique of 3D image and video has been progressed in form of 3DAV which is a part of MPEG. As we can identify in case of 3DAV, the coding technique has high possibility to be formed into the hybrid type which is a merged, refined, or mixid with the various previous technique. Therefore, we wish to present the relationship between various image/video coding techniques and digital hologram In this paper, we propose an efficient coding method of digital hologram using standard compression tools for video and image. At first, we convert fringe patterns into video data using a principle of CGH(Computer Generated Hologram), and then encode it. In this research, we propose a compression algorithm is made up of various method such as pre-processing for transform, local segmentation with global information of object image, frequency transform for coding, scanning to make fringe to video stream, classification of coefficients, and hybrid video coding. Finally the proposed hybrid compression algorithm is all of these methods. The tool for still image coding is JPEG2000, and the toots for video coding include various international compression algorithm such as MPEG-2, MPEG-4, and H.264 and various lossless compression algorithm. The proposed algorithm illustrated that it have better properties for reconstruction than the previous researches on far greater compression rate above from four times to eight times as much. Therefore we expect that the proposed technique for digital hologram coding is to be a good preceding research.

This study was conducted to examine the effects of dietary Mogchotan(the mixture of charcoal and pyroligneous acid, 80:20, w/w) supplementation on fattening performance, fatty acid composition and the physico-chemical characteristics of meat in pigs. The present study was also stressed to investigate the possibility of industrial utilization of charcoal and pyroligneous acid as a livestock feed additive. Weight gain and feed conversion in pigs fed the Mogchotan supplemented diet were higher than those of the control group. In fatty acids composition, palmitic acid(C16:0) contents of Mogchotan treatment groups were lower than that of control group. However, Mogchotan supplementation increased C16:1, C18:0, C18:1, C18:2 and C18:3 contents when compared with control group pigs. Also, Mogchotan supplementation groups decreased saturated fatty acids level than control group. On the other hand, Mogchotan supplementation showed higher unsaturated fatty acids value, especially polyunsaturated fatty acids value compared to control group. The carcass pH of pigs fed the Mogchotan tended to be higher than control, but was not significantly different. The water holding capacity was significantly higher in pigs fed the 3.0% Mogchotan-supplemented diet than those of other treatment groups(p<0.05). Altogether, it has been suggested that dietary $1{\sim}3%$ of Mogchotan supplementation improved the fattening performance and meat quality in pigs.

In the era of the 4th Industrial Revolution, as the importance of creative talent became more and more important, we recognized the urgent need for start-ups to innovate new growth industries and creative talents to lead these eras.And the importance of entrepreneurship education emphasized in entrepreneurship education and the necessity of creativity competency education.However, there is a lack of research on how creativity competency education affects entrepreneurship intention for college students. Especially, research on the moderating effect of social support on the effect of entrepreneurship through education is very insufficient. The purpose of this study is to examine the effects of creativity competence education on the will of entrepreneurship and empowerment of social support. For this purpose, 393 college students were used for empirical analysis for 1 month from August 2016. As a result of this study, the ability of communicative communication and creative problem solving had a positive effect on self - efficacy. On the other hand, innovative work behavior abilities did not directly affect self-efficacy. In addition, creative problem solving ability and innovative work behavior ability had a positive effect on the will to start up. Collaborative communication skills, however, did not directly affect the willingness to start a business. Self - efficacy has a positive effect on the will of founding. Finally, the moderating effect of social support between self-efficacy and willingness to work was not directly affected. The implication of this study is that the effect of the creativity competency education on college students has a positive effect on the self - efficacy of self and the positive influence on the will to start up. The results of this study are as follows. First, it is found that the influence of social support (parental support) is not positively influenced by the control effect of the parents. In the case of college students, As well as the need to do so. Therefore, in order to further increase the willingness of young people to establish a university in the university, it is necessary to provide education and programs not only for direct education for college students, but also for improving the understanding of the talents and entrepreneurship required by the age of their parents.

The drastically changing society has brought diverse types of families, and these diversities are changing the concept of the word 'family' itself. Inevitably, these changes cause different viewpoints among family members, developing into conflicts and social issues. In this paper, generational family problems, which are caused by changes within the family as a result of the variously, diversely changing society, are observed to suggest a resolution. Looking into the functional variety that today's structural change within a family demands, several positives changes described below have been observed; Firstly, the change in the way of interaction among family members; Secondly, the demand for continuance on relational functions including love, care, etc, as a psychological resource of family; Thirdly, the conversion from form's sake relationship to actual relationship; and Lastly, the usage of a clearer communications network. The interaction between the parent-children relationship, according to the changes in family life cycle, is also re-focused to seek resolutions for intergenerational conflicts. The results are as follows; Firstly, the changeability of various family types today must be accepted, and the functional aspects of changing families must be emphasized ; Secondly, the mutual-exchanging value of each generation must be accepted, strengthening relational functions between generations; Thirdly, it is necessary to refocus filial piety. In other words, though the intergenerational transmission of family functions may become the basis of lineage and clan formation, it won't be possible without interaction between generation.

In this study, We developed VR (Virtual Reality) geological resources based on the Geo Big Data of the Big Data platform that provided by the Korea Institute of Geoscience and Mineral Material (KIGAM). So students selected the theme of lessons by using these resources and we operated Remote classes using the materials that developed as to Virtual Reality. Therefore, the geological theme maps provided by the Geo Big Data Open Platform were reconstructed and produced materials were created for Study about Real Korean geological outcrops grounded in Virtual Reality. And Topographic information data was used to produce class materials for Remote classes. Twenty students were selected by Random sampling, and data were collected by conducting a survey including interviews to confirm the change in students' perception of remote classes in virtual reality geological data development and the effect of the classes, so data were analyzed through inductive categorization. The results of this study are as follows. First, students showed positive responses in terms of interest, utilization, and knowledge utilization as taking remote classes for developing geological data in virtual reality geological data. This is the result of showing the adaptability of diverse and flexible learning getting away from a fixed framework by motivating and encouraging students and inducing cooperation for communication. Second, students recognized distance education in the development of Virtual Reality geological data as 'Realistic hands-on learning process', 'Immersive learning process by motivation', and 'Learning process of acquiring knowledge in the field of earth science'.

The purpose of this study is to investigate the perception on video material making and the effect on science teaching ability after conducting non-face-to-face teaching material making activity for elementary pre-service teachers. This activity consisted two processes. One is that elementary pre-service teachers conduct inquiry, understand related science concepts, analyze science textbooks and then make video material. The other is that they watch video materials produced by colleagues. This study was conducted on 89 elementary pre-service teachers for 8 weeks. After this activity was completed, the perception on video material making and the effect on science teaching ability of elementary pre-service teachers were investigated, and the results were analyzed. In the process of making and watching non-face-to-face teaching materials, elementary pre-service teachers showed positive results in teaching-learning, video production, and emotion and attitude toward video material making. In addition, it was found that they improved their science teaching ability through this activity and were very satisfied with this activity. However, they also mentioned several disappointments such as exclusion of learners' right to self-determination, lack of various communication channels, and errors in content of materials. This suggests that if these problems are solved, non-face-to-face classes can also be a good form of class.

This study examined the overall effect size of the batterer intervention programs aimed at reducing violent behavior. This study calculated the 18 results and the 115 effect sizes of 11 theses published from 2000 to 2017 in Korea. It was demonstrated that the effect of an offender's program on the change in violent behavior was significant at both the practical and treatment level. The effect size was high in the order of control behavior, emotional violence, and physical violence. The effects of dependent variables other than violence were also researched. The batterer program positively changed the participant's attitudes in terms of sex-role and partner violence. Furthermore, it decreased the level of anger and depression, and enhanced self-esteem and communication skills thus increasing satisfaction in marital relationships. In addition, this study examined the factors that influence the effect of the offender's program in terms of the decrease of violent behavior. Upon analysis, it was examined that the moderating effect was great in the approach model and counsel form. More specifically, it was revealed that the feminist-cognitive behavioral models had a greater effect than the compromise model or single model. In terms of counsel forms, group counseling formed only of male offenders had greater effect than couples treatment group. Based on these findings, this study discussed the practical means for increasing the effect of batterer intervention programs.

The purpose of the study is to review the research trends of human development and family studies which published in the Journal of the Korean Home Economics Education for last 20 years. A total of 93 studies were analyzed in the area of nature and philosophy of Home Economic Education, curriculum, teaching-learning method and human development and family studies. Research topics mainly examined in the area of curriculum development, application of teaching methods, psychological and school adjustment of the adolescent and family relations. Reviews in methodological issues result in the heavy usage of survey method with self-administered questionnaires, convenient sampling and descriptive studies. Although research on human development and family studies in Home Economic Education has increased in quantity, there are greater needs to develop studios with representative subjects, various research methods, teaching - learning methods, and teaching materials to capture the rich complexity of individual development and family life. Limitations on previous studios and implications for future studies were also discussed.

As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.
