The use of instructional media in nursing education was investigated using a descriptive research methodology. Data were collected from 199 professors teaching in the areas of Fundamental Nursing (48 subjects), Adult Nursing(56 subjects), Pediatric Nursing(49 subjects), and Community Health Nursing(46 subjects). 120 professors were from 3-year college of nursing and 79 professors were from 4-year college of nursing, Data were analyzed using descriptive statistics (mean, standard deviation), and ANOVA with SPSS $PC^+$ program. The results are as follows. 1) The general attitude of the subjects toward the use of instructional media was positive(mean : 3.75). However, from the ANOVA result the subjects from 4-year college of nursing had more positive attitudes in the areas of media utilization and supply system. Most subjects had high interest in the areas of effectiveness of the media, and media literacy in using instructional media. 2) OHP(mean was 3.76) and VTR(mean was 3.36) were the most used instructional media in nursing education. These media were efficiently supplied by the school. However, other media like CD-ROM, Opaque Projector, and LCD or beam Projector were not sufficiently provided by the school. 3) The main reasons to use instructional media were that the use of media is effective to raise students' attention and learning motivation. 4) Insufficiency of the media and environment to use media were the causes of the lack of using instructional media. 5) The use of PC communication of internet, LCD or beam Projector, and Computer Graphics was low. The reasons were that the subjects did not have enough knowledge and skills to use these media, and there was lack of media or environment. 6) In general, environment to use media of the 3-year college of nursing was worse than that of 4-year college of nursing. However, there was no significant differences between the two groups in the use of media related to their position, and subject. On the basis of the study results professors teaching nursing have positive attitudes to use instructional media but the lack of media supply or facility to use media limited the use of instructional media.

The traditional mass media function of conveying information and forming public opinion has rapidly changed into an environment in which information and opinions are shared through social media with the development of ICT technology, and such social media further strengthens its influence. In other words, it has been confirmed that the influence of the public opinion through the production and sharing of public opinion on political, social and economic changes is increasing, and this change is already in use on the political campaign. In addition, efforts to grasp and reflect the opinions of the public by utilizing social media are being actively carried out not only in the political area but also in the public area. The purpose of this study is to explore the possibility of using social media based public opinion in educational policy. We collected media data, analyzed the main topic and probability of occurrence of each topic, and topic trends. As a result, we were able to catch the main interest of the public(the 'Domestic Computer Education Time' accounted for 43.99%, and 'Prime Project Selection' topics was 36.81% and 'Artificial Intelligence Program' topics was 7.94%). In addition, we could get a suggestion that flexible policies should be established according to the timing of the curriculum and the subject of the policy even if the category of the policy is same.

It was main objectives to find the learners characteristics and educational effects of cyber agricultural technology courses in RDA. For the research, it was followed by literature reviews and internet based survey methods. In internet based survey, two staged stratified sampling method was adopted from cyber training members database in RDA along with some key word as open course or certificate course, and enrollment years. Instrument was composed through literature reviews about cyber education effects and educational effect factors. And learner characteristics items were added in survey documents. It was sent to sampled persons by e-mail and 316 data was returned via google survey systems. Through the data cleaning, 303 data were analysed by chi-square, t-test and F-test. It's significance level was .05. The results of the research were as followed; First, the respondent was composed of mainly man(77.9%), and monthly income group was mainly 2,000,000 or 3,000,000 won(24%), bachelor degree(48%), fifty or forty age group was shared to 75%, and their job was changed after learning(12.2%). So major respondents' job was not changed. Their major was not mainly agriculture. Learners' learning style were composed of two or more types as concrete-sequential, mixing, abstract-random, so e-learning course should be developed for the students' type. Second, it was attended at 3.2 days a week, 53.53 minutes a class, totally 172.63 minutes a week. They were very eager or generally eager to study, and attended two or more subjects. The cyber education motives was for farming knowledge, personal competency development, job performance enlarging. They selected subjects along with their interest. A subject person couldn't choose more subjects for little time, others, non interesting subject, but more subject persons were for job performance benefits and previous subjects effectiveness. Most learner was finished their subject, but a fourth was not finished for busy (26.7%). And their entrying behavior was not enough to learn e-course and computer or internet using ability was middle level as software using. And they thought RDA cyber course was comfort in non time or space limit, knowledge acquisition, and personal competency development. Cyber learning group was composed of open course only (12.5%), certificate only(25.7%), both(36.3%). Third, satisfaction and academic achievement of e-learning learners were good, and educational service offering for doing job in learning application category was good, but effect of cyber education was not good, especially, agricultural income increasing was not good because major learner group was not farmer, so they couldn't apply their knowledge to farming. And content structure and design, content comprehension, content amount were good. The more learning subject group responded to good in effects, and both open course and certificate course group satisfied more than open course only group. Based on the results, recommendation was offered as cyber course specialization before main course in RDA training system, support staff and faculty enlargement, building blended learning system with local RDA office, introducing cyber tutor system.

Owing to recent advanced techniques in information and communication technology(ICT), our daily life has been changing very quickly and our life style has also been affected greatly. In the current knowledge and information society, the disabled can have a right to enjoy benefits of advanced ICT technologies. However, there is a barrier called digital divide so that the disabled have some difficulties to communicate to the world with ICT technologies. In this sense, our job is to close digital divide and let the disabled enjoy benefits of ICT technologies. Recently there have been some research works to close digital divide between the disabled and the non-disabled. Among various attempts to close digital divide, improving web accessibility for the disabled is the biggest concern since web is a still representative tool among ICT tools. The purpose of this paper is to propose some practical guidelines for improving web accessibility for the disabled. The proposed improvement guidelines are developed based on the existing web accessibility guidelines and are upgraded for more adaptable to the disabled. Our principles are based on the following philosophy. First, any input transmission must be more confirmed. Second, prevent any instant request. Third, allow the disabled to record or store the contents if necessary. Fourth, reduce physical movement for the disabled. Fifth, provide more interaction tools for the disabled.

Recently, the use of real-world image data has been increasing to express realistic virtual environments in various application fields such as education, manufacturing, and construction. In particular, with increasing interest in digital twins like smart cities, realistic 3D urban models are being built using real-world images, such as aerial images. However, the captured aerial image includes shadows from the sun, and the 3D city model including the shadows has a problem of distorting and expressing information to the user. Many studies have been conducted to remove the shadow, but it is recognized as a challenging problem that is still difficult to solve. In this paper, we construct a virtual environment dataset including the height map of buildings using 3D spatial information provided by VWorld, and We propose a new shadow detection method using height map and deep learning. According to the experimental results, We can observed that the shadow detection error rate is reduced when using the height map.

This study was to investigate weight-control experience disorder and nutrient intake of college student attending web class via the internet. The subject were 1200 college students(392 male, 808 female) attending web class concerned with nutrition and weight control. This cross-sectional survey was conducted by self-administered questionnaire and data were analyzed by Students t-test and $\chi$$^2$-test. Nutrient intake collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Mean height, weight and RBW(relative body weight) of the male college students were 174.7 cm, 68.0 kg and 101.2%, respectively. Mean height, weight and RBW of the female college students were 162.3% cm, 52.7% kg and 95.3% respectively. Among the male college students, low weight were 1.0%, underweight were 12.8%, overweight were 12.5%, obese were 6.9% by RBW standard. Among the female college students, low weight were 5.1%, underweight 30.2%, overweight were 5.2%, obese were 1.5% by RBW standard. Percentages of weight control experience were 21.7% and 67.0% in the male and female college students, respectively. According to RBW, 22.4% of the weight control experience group were low weight or underweight in the female college students but none of weight control experience group were low weight or underweight in the male college students. Percentage of eating disorder were 6.8%(2.8%, male, 8.7% female) in the college students. Among the female college students, most nutrient intakes were significantly lower in the weight-control experienced group compared to the weight-control nonexperienced group. Among the male college students, there was a tendency that the intake of nutrients, except carbohydrate, calcium and vitamin A was higher in the eating disorder group compared to the non-eating disorder group. However, among the female college students, there was a tendency that the intake of nutrients, except calcium and thiamin was lower in the eating disorder group compared to the non-eating disorder group. Therefore, nutrition education via the internet is required for college students to know proper weight loss methods, desirable eating habits and eating disorder problem well.

'Science Garden' is a science program that develops acquirements of science & technology at an early stage through experiential study and inspire the spirit of scientific inquiry by carrying out laboratory work, science movie, science lecture, scientific work, outdoor activities, computer classes and science experiment which is hard to do through the regular educational course. It is targeted grade 4,5,6 students during summer and winter vacation. 'Science Garden' is conducted by selective participation freely. It is a wholelistic activity that develops children's potential talents or creativities, improves interest and attitude toward science, and also gives opportunity for self-realization by extending capacity for inquiry to show each student's ability. This study is observed and is compared how it is conducted in elementary school using qualitative study. This study is used narrative observation, in-depth interview and document analysis. Objects of narrative observation are two elementary schools, each from Jellabukdo and Gyeonggido, and 7 teachers were interviewed in-depthly. Here are results of the study. 1 A teacher in school G never takes part in student activities, tends to be indifferent to classes, but focuses on observation and experiment in laboratory. And feedback or evaluation about student's activity is never done. On the other hand, a teacher in school S guides students to understand the principals of science on themselves, and wide variety forms of activities such as role playing, discussion, and games are being done. But an effort to evaluate student's activity is not being made properly. 2. Teachers set a high valuation on the need of 'Science Garden'. Observing the way of conducting 'Science Garden', usually teachers who is in charge of science for official work is selected as a teacher in charge, and groan under a heavy burden of conducting it without anyone's help. Participating students are selected by volunteering or teacher's recommendation, but because of low Participation rate, teachers have difficulty in conducting it. Plan for conducting ‘science Garden’ is made 20 days before it, after getting an official document from Office of Education, refering to booklets produced by National Jungang Science Institute, or data from Office of Education, and internet. Teachers evaluate rarely Most school principals have interest in 'Science Garden' but parents are not well aware of it, The budget is made at the same time with the plan, and scale is varied between 200,000∼500,000 won. Because of the improper way of selecting teacher in charge, difficulty in selecting students, heavy works caused by planning, conducting the program, as well as reporting teacher's work, and lack of parents' awareness, 'Science Garden' has been conducted formally and superficially. Next gives you direction to change, for the right way of conducting' Science Garden'. It is important to motivate competent teachers to instruct students actively. For students' active participation, They should publicize thoroughly beforehand, and develope 'Science Garden' program for teachers to be able to make better use of it. Evaluation of student activities and program should be done in the aspect of developing students’ faculties. Beside of school facilities, they need to put diverse local facilities and places to practical use for immediate natural experience. And not only separate schools but also associated form of schools to conduct it is necessary.
