The purpose of this study was to analyze the results of teachers' self-evaluation on their health teaching behaviors, then to furnish the basic data to be able to improve teachers' health teaching activities and the educational issues on the education of teachers. To put above aims into practice, these were required: 1. Are there any differences in the results of self-evaluation on health teaching behaviors factors by teachers? 2. Are there any differences in the results of health teaching self-evaluation whether he/she take P.E as major of study in-serviece training period? 3. Does it have any influence on the results of health teaching self-evaluation whether he or she completed on the job training for the school health? 4. Are there any differences in the results of health teaching self-evaluation by sex and career? To carry out a research for this purpose, the factors of health teaching self-evaluation were divided into the clearness of the procedure, the active interaction, the variety of the ways showing the contents, and the individualization of the procedure. Then a questionnaire form, consisting of 28 specific inquires to evaluate health teaching behaviors, was delivered and conducted by 450 teacher of the elementary school in Kyungki-do. The analysis of data was done by SPSS; producing mean and standard deviation and they were inspected statistically to compare the evaluation levels and find out the differences by teachers' personal variables. The conclusion were as follows: 1. In the self-evaluation level of teachers' health teaching behaviors, teachers showed 68.23 point as are percentile distribution. And it was in order of a school-nurse(71.68), an athletic teacher(67.29), and a class-room teacher (65.66). Score obtained by teacher was statistically significant difference (p〈.001) 2. In the factors affecting to teachers' health instruction, “active interaction” showed the highest score(18.55), “variety of ways showing the contents”(17.38), “clearness of the procedure” (16.70), and “individualization of the procedure” (15.59). In the analysis of the differences by teachers, according to factors, there were significant differences in “active interaction”, “variety of the ways showing contents”, “clearness of the procedure”(p〈.001). 3. Self-evaluation score for graduates from Dept. of P. E in Teachers' collage was not significant difference compared with other majors(p〉.05). 4. Teachers receiving health education was significantly higher self-evaluation score than that of teachers not-receiving health education (P〈.01). 5. Self-evaluation score of female teacher was significant difference compared with that of male teacher (p〈.001). 6. Career (working duration) did not influenced to self-evaluation score on health teaching behaviors (P〉 .05). On the basis of the conclusion of this study, the next are suggested: First, the further studies to make use of the results of health teaching behaviors and to examine the effect are needed. Second, the further studies to examine the relations between academic achievement and teachers' major(a school-nurse, an athletic teacher, and a class-room teacher) are needed. Third, the following studies to improve health teaching by both teachers' self-evaluation on health teaching behaviors and students' evaluation of teachers, and to find out more effective health teaching, are needed. Fourth, Health education for pre-service training course and On-the-Job training program are need the effective factors on the teachers' Health teaching obtained from this study.
The contents of starch, moisture, crude protein, crude fat, crude fiber, and ash of different varieties of potatoes were analyzed. The average starch contents of Go-woon, Ha-ryoung, Dae-seo, Jo-won, Ga-won potatoes were $17.9{\pm}0.2$, $18.0{\pm}1.7$, $17.7{\pm}0.5$, $14.8{\pm}0.4$, and $16.2{\pm}1.0%$, respectively. The ground powder of each starchy substrate was suspended in distilled water, and then liquefied, saccharified, and fermented by Saccharomyces cerevisiae ATCC26603 at $30^{\circ}C$ for 4 days. By statistical analysis, the effectiveness of the contents of the different components of the potato tubers on the ethanol production were examined. The results showed that the starch content positively affected the ethanol production. while moisture content affected negatively the ethanol production. Ethanol production from the 5 different varieties of potato tubers harvested on different time were examined and the results indicated that both of potato variety and the harvesting-time significantly affected the ethanol production. Among the several varieties of potato, Ha-ryoung produced the highest yield of ethanol as much as $94.3{\pm}1.9$ L/ton or $3111{\pm}62.7$ L/ha.
Since the inception of Internet Protocol TV's real-time service on January, 2009, technological challenges and lack of content diversity of IPTV have been cited as problem areas. While past researches focused on IPTV's technological, industrial and policy facets, this research surveyed the viewers' viewing and usage patterns, and the level of service satisfaction among actual audiences of MegaTV, SKBroadband, and LGTV since January. The results show that subscription fee and content types were the two dominant determinants in audience's choice of a particular IPTV company. The high users of IPTV were on average aged between 30-39, and women tended to be heavier users than men. The surveyed audience also regarded IPTV to be more similar to the Internet than any other medium such as Cable TV and Satellite TV. IPTV audience cited 'lifestyle service' and 'additional service' offerings to be highly relevant to their usage and satisfaction; interactive service and educational service also showed high correlation to usage and satisfaction. The most watched contents on IPTV were domestic TV series, followed by foreign movies and variety shows. 'Fees for additional features,' 'lack of real-time terrestrial TV service', and 'lack of content variety' were the major areas of concern for IPTV viewers. They answered that the monthly fee was the most important factor in the selection of IPTV. Use of pay-per-view contents and add-on interactive service fees were also seen as problematic. With regards to future usage, the IPTV audience revealed that they were very sensitive and reluctant to pay for additional services. While existing researches concentrated on IPTV's technological problems and lack of content diversity, this study illuminated the more pragmatical side of the viewers, namely, the importance of price in audience's selection of an IPTV service provider. From these results, it is recommended that, before doing anything else, the service providers try to meet the audience's expected price points in order to garner the full potential of IPTV and the attendant mass audience.
With the recent emergence of VR contents, a lot of attention has been drawn on actual image based VR 360° video production using photography system. It was very complicated and difficult to make conventional VR contents. Therefore, such making was performed only in a research level. These days, as cameras have been made smaller, VR live-action has become more common in contents makers. In the circumstance, this study tries to compare a variety of contents making equipment based on action-cam that is mainly used for producing VR contents, and suggest their problems. To solve the problems, this study uses a cinema grade camera to do VR filming. As a result, it is revealed that, in order to make VR contents with quality, it is necessary to use a cinema grade camera, rather than an action cam, and to conduct technical research for standard lens based contents.
Varietal and annual variations in the contents of ${\beta}$-glucan fractions per weight grain samples were examined in sixteen covered and eighteen naked barley and five oat cultivars developed in Korea. Also, the effect of pearling on ${\beta}$-glucan content was investigated. Average contents of total, soluble and insoluble ${\beta}$-glucan fractions were 5.25, 3.72, and 1.53%, respectively, in covered barley, and 5.86, 3.51, and 2.35%, respectively, in naked barley. Soluble ${\beta}$-glucan content was higher in covered barley, though total ${\beta}$-glucan content higher in naked barley. The total and insoluble ${\beta}$-glucan contents were higher in pearled grains. Total ${\beta}$-glucan content was higher in waxy barley than in non-waxy barley. Duwonchapssalbori, a two-rowed and waxy naked barley cultivar, was highest in total, soluble and insoluble ${\beta}$-glucan contents. Highly significant positive correlations were observed between total ${\beta}$-glucan and soluble ${\beta}$-glucan contents both in covered and naked barley. There were significant annual variations in total ${\beta}$-glucan content in barley. Average contents of total, soluble and insoluble ${\beta}$-glucans of oat cultivars were 4.33, 3.44, and 0.89%, respectively. Contents of all fractions of ${\beta}$-glucans were higher in barley than in oat. These results would be useful for the breeding of high ${\beta}$-glucan variety and also for the use barley and oat as valueadded food ingredients.

The Fourth Industrial Revolution has differentiated technologies such as artificial intelligence, IoT(Internet of things), big data, and mobile. As the civilization develops more and more, humanity enjoy the cultural activities more than economic activity for the food and shelter. The platform structure based on the advanced information technology of the present will expand the cultural contents area in a variety of ways. Cultural contents respond sensitively to changes in consumer and will be useful experiences of human activities. Therefore, it should be noted again that the contents industry should not be limited to the discussion of the application of the fourth technology, but should be produced with emphasis on useful experiences of human being. In other words, the discussion of human activities around cultural contents should be focused on how to apply beyond the use of fourth industrial technology. Therefore, it is necessary to analyze the basis of the successful storytelling of the planning stage to connect the fourth industrial technology and human useful experience as a method for developing cultural contents, and to build and propose a model as a strategic method. This study analyzes domestic and foreign cases made by using big data among the visual contents which show continuous increase of consumption among culture industry field, and draws success factors and limit points. Next, we extract what is the successful matching factor that influenced consumer 's consciousness, and find out that the structure of culture prototype has been applied in the long history of mankind, and presents it as a storytelling model. Through the above research, this study aims to present a new interpretation and creative activity of cultural contents by presenting a storytelling model as a methodology for connecting creative knowledge, away from the general interpretation of social phenomenon applied with big data.
This is to study intellectual property(IP) protection of contents which is related with transactions upon internet network. Issues of electronic transaction and infringement cases were studied and analyzed for intellectual property protection. Upon those study, utilization and activation of contents, dispute settlement and method of IP protection were suggested. To achieve this study purpose, it consists of 5 chapters. In chapter 1 introduction, it's mentioned purpose, scope, and method of this study. In chapter 2, outline of contents and e-Commerce, and subject of IP protection upon internet were studied. In chapter 3, issues and dispute factors of IP were discussed and infringement cases were analyzed. It found out that infringements would be variety and complex due to technology rapidly changes. In chapter 4, IP protection plan and responsibility of webmaster were studied and emphasized to protect IP upon Internet. Also, protection against infringement and method of dispute resolution were studied and suggested the method. In this study, the protection plan was suggested because IP protection of contents in internet would be many cases upon internet technology. It found out that technology was important for business expansion of contents, e-Commerce and IP protection, and to enact a law related with IP. In chapter 5 conclusion, this study was summarized and further research was suggested. This study results are 1. IP related laws had better enact or revise to meet internet technology changes for IP protection timely, 2. local laws are to change and develop to harmony with international norm and trends, 3. consolidation of IP related laws for unification of IP statement should be incurred to avoid unnecessary energy of legislation and not to create dispute matters. That's also for customer satisfaction. In conclusion, not to incur ADR and for IP protection of contents, IP related laws would be promptly made or revised, according to technology change trends and for international harmony, That's for internet related industry development and customer satisfaction.
The growth characteristics and damage of naked barley infected with barley yellow mosaic virus (BaYMV) were investigated between resistant and susceptible varieties in habitual field plot of BaYMV BaYMV of the barley plants with typical disease symptom were identified by enzyme linked immunosorbent assay (ELISA) test. The visual degree (0-9) based on disease symptoms of BaYMV was different as 9 and 1 between susceptible variety Baegdong and resistant variety Naehanssalbori, respectively. Susceptible variety, Baegdong showed significant damage in culm length, number of kernel per spike and tiller per square meter but not in 1,000 kernel weight, so these results caused yield reduction to only 80% comparing to the control. Seed germination did not affected by BaYMV infection both in susceptible and resistant variety. In grain quality test, abortive grain yale and crude protein content were significantly increased compared to the control. The relationships between BaYMV infection and growth characteristics showed the negative correlations in culm length, number of tiller, 1000 kernel weight and yield, but it showed the positive correlation in crude protein contents. These results implied that BaYMV can affect not only barley growth and yield but grain quality.
This study's purpose is a search for the conceptual variety of media education. For this purpose, media education's surrounding is used to search by two of view. First view is about the condition of media education that includes an advent of new media, consumer's attitude change to user and variety of educational change. And then the variable paradigm of media education are viewed how it is connected with the theories of media with time. Change of surrounding and theoretical variety tell us why concept of media education should be revised. So, in this study, many scholar's definitions of the media education are regarded. From the rally stage of education for the television, the media education's definition has formed as new field. After that, media education expanded to the media literacy as communication competence with an advent of new media. This means that media education would be variably extend to verbal media education, critical interpretation of the contents and communication with community.
The purpose of this study was to investigate the quality attributes and importance that affects their satisfaction with respect to lunchboxes amongst children from low-income families in Korea. In case of $1-3^{rd}$-grade elementary school, 57.1% received lunch box through the community child center, while 45.2%, 68.5% and 80.7% of $4-6^{th}$-elementary school, middle school, and high school students received the lunch box from home, respectively. Typically, in 40.2% of all grades, the time to eat the meal was within 1~2 hours of delivery, and 34.0% consumed the lunch within 2~6 hours of delivery. With respect to intake of the contents of lunchboxes, 72.0% of the participants answered that they ate 80% of the lunchboxes delivered and 24.9% only ate 50% of the content of lunchboxes. The largest leftover were vegetables (26.9%), and the reason for leaving food was 'do not like to eat (36.1%)' followed by 'no taste (32.6%)'. Regarding improvements in delivery lunchboxes, elementary school students selected 'taste', while middle school and high school students selected 'variety of menu'. The 'nutrition (3.69 point)' of the lunchboxes was the highest satisfaction and the 'variety of menu (3.34 point)' was the lowest. In all grades, 'nutrition' and 'hygiene' were considered to be important as quality attributes of the delivery lunchboxes, and satisfaction was also high. On the other hand, in the $1-3^{rd}$-grade elementary school, 'variety of menu' and 'amount of side dish' were important but satisfaction was low. The $4-6^{th}$-grade elementary school, middle school and high school students stated that 'taste' and 'variety of menu' were important, but satisfaction was low.
