Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

Purpose Corporate technology leakage is not only monetary loss, but also has a negative impact on the corporate image and further deteriorates sustainable growth. In particular, since SMEs are highly dependent on core technologies compared to large corporations, loss of technology leakage threatens corporate survival. Therefore, it is important for SMEs to "prevent and protect technology leakage". With the recent development of data analysis technology and the opening of public data, it has become possible to discover and proactively detect companies with a high probability of technology leakage based on actual company data. In this study, we try to construct profiles of enterprises with and without technology leakage experience through profiling analysis using data mining techniques. Furthermore, based on this, we propose a classification model that distinguishes companies that are likely to leak technology. Design/methodology/approach This study tries to develop the empirical model for prevention and protection of technology leakage through profiling method which analyzes each SME from the viewpoint of individual. Based on the previous research, we tried to classify many characteristics of SMEs into six categories and to identify the factors influencing the technology leakage of SMEs from the enterprise point of view. Specifically, we divided the 29 SME characteristics into the following six categories: 'firm characteristics', 'organizational characteristics', 'technical characteristics', 'relational characteristics', 'financial characteristics', and 'enterprise core competencies'. Each characteristic was extracted from the questionnaire data of 'Survey of Small and Medium Enterprises Technology' carried out annually by the Government of the Republic of Korea. Since the number of SMEs with experience of technology leakage in questionnaire data was significantly smaller than the other, we made a 1: 1 correspondence with each sample through mixed sampling. We conducted profiling of companies with and without technology leakage experience using decision-tree technique for research data, and derived meaningful variables that can distinguish the two. Then, empirical model for prevention and protection of technology leakage was developed through discriminant analysis and logistic regression analysis. Findings Profiling analysis shows that technology novelty, enterprise technology group, number of intellectual property registrations, product life cycle, technology development infrastructure level(absence of dedicated organization), enterprise core competency(design) and enterprise core competency(process design) help us find SME's technology leakage. We developed the two empirical model for prevention and protection of technology leakage in SMEs using discriminant analysis and logistic regression analysis, and each hit ratio is 65%(discriminant analysis) and 67%(logistic regression analysis).

The present study assessed the amount of $CO_2$ uptake owing to concrete carbonation through a case study for an apartment building with a principal wall system and an office building with Rahmen system under different exposed environments during use phase and recycling application. The $CO_2$ uptake assessment owing to concrete carbonation followed the procedure established by Yang et al. As input data necessary for the case study, actual surveys conducted in 2012 in Korea, which included data about the climate environments, $CO_2$ concentration, lifecycle inventory database, life expectancy of structures, and recycling activity scenario, were used. From the comparisons with the $CO_2$ emissions from concrete production, the $CO_2$ uptake during the lifetime of structures was estimated to be 5.5~5.7% and that during recycling activity after demolition was 10~12%; as a result, the amount of $CO_2$ uptake owing to concrete carbonation can be estimated to be 15.5~17% of the $CO_2$ emissions from concrete production, which roughly corresponds to 18-21% of the $CO_2$emissions from cement production as well.

This study examined to find out the relationship between nutritional knowledge and food habit of the students majoring food & nutrition(218 students) and the students majoring Korean oriental medicine(286 students). The results of this study are as follows; 1)The intake of vegetable and dairy products is high for the students majoring food & nutrition(p＜0.01), and the intake of instant food is low for the students majoring Korean oriental medicine(p＜0.01). 2)In the value of diet, the ratio which acknowledges the importance of the relationship between the diet and the nutrients is high for the students majoring food & nutrition (p＜0.01), and the ratio which acknowledges the diet as the way to remove hunger or to enjoy eating is high for the students majoring Korean oriental medicine(p＜0.01). The ratio of the students who acknowledge taste, nutrition and preference as the important factors in selecting foods is high for the students majoring food & nutrition(p＜0.01). The ratio of regularity in each meal, consuming time, and the food quantity is high for the students majoring Korean oriental medicine(p＜0.01). 3)The total score of 20 inquiring items about nutritional knowledge is high for the students majoring food & nutrition(p<0.01), and especially the mark is high in such items inquiring the relationship between animal fat and nutrition(p<0.01), the relationship between water and obesity(p<0.05), the relationship between cholesterol and food(p<0.01), the recommended energy quantity(p<0.05), and the vitamin B group (P<0.01). According to this study, it is hard to determine that there is inevitable positive relationship between diet habits and nutritional knowledge. The students majoring food and nutrition know better than the students majoring Korean oriental medicine about the relationship between diet, health and nutrients however they can not practice what they blow when selecting foods. On the other hand the students majoring Korean oriental medicine show lower marks in food habits and nutritional knowledge than those of the students majoring food and nutrition; however, they show higher marks in practicing regular diet. According to this result it is necessary to increase the subjects related nutrition in the curriculum not only lot the students majoring food & nutrition to practice their nutritional knowledge in their actual life but also for the students majoring Korean oriental medicine to obtain correct nutritional knowledge and information.

Methods : The subjects in this study were 250 people who received education in two different lifelong education institutions in the city of Busan. After a survey was conducted from May 23 to June 15, 2011, the answer sheets from 217 respondents were analyzed. Results : 1. As for the general characteristics of the respondents, the men(52.1%) outnumbered the women. Those who were in their 60 and up(47.5%) made up the largest age group, and the married people(65.4%) outnumbered the unmarried ones. By occupation, the company employees(20.3%) made up the biggest group. By education, the greatest group was high-school graduates(36.1%). By monthly mean income, the biggest group gained an income of 2.01 million won or more(36.9%). As to medical security, community-based insurance was most prevailing (36.9%). In terms of health promotion, the largest group worked out to stay fit(52.4%). 2. Regarding oral health knowledge, they had a good knowledge about the cause of dental caries(56.7%), but they weren't well aware of the right time for regular dental checkup(47.9%). In relation to oral health care, regular scaling wasn't prevailing(16.9%). 3. Regarding connections between the general characteristics and satisfaction with prosthesis, the less-educated respondents expressed significantly more dissatisfaction(p=0.015). By monthly mean income, those who had a smaller income were dissatisfied in general(p=0.028). Conclusions : The findings of the study illustrated that it's required to spread awareness of the importance of oral health among people in general, and that differentiated incremental oral health care should be provided for different age groups. In order to raise the satisfaction of patients with prosthesis, how to relieve their pain and anxiety and how to adjust prosthetic treatment cost properly should carefully be considered. In addition, the government should take measures to offer assistance for the low-income classes in preparation for an increase in the elderly population.

The purpose of this article is to prove the fun of cartoon has related in Reality. Ultimately, it will be occurred the expanding result in contact with reader's reality perception. I had pointed out this issue in introduction. Although Fun is our vital power, almost people recognize it as imagination result which is not related in Reality. As the result, we overlooked Fun is contacted in Reality recognition. Creation method of cartoon story emphasize "the Individual character" and "the original nature" also. As this result, it has limitation which neglect "Reality". In main subject, I explained the meaning of Fun and Reality in feeling Korea Cartoon. First, we looked around a theoretical background of fun. With take surveying for various fun characters in several category of cartoon. We can confirm that it was occurred the results contacting "Enlargement of actual recognition" commonly. Second, the main issue of Korea cartoon was "Reality" historically. But, described Reality in cartoon is different from true Reality. Therefore, cartoon is imagined Reality of writer. So he make a heros and make a fun putting a folk tail. Third, described Reality in Korea cartoons make a fun and reader's consensus which is from emotional reality. With limitation of writer's "Reality recognition", almost writers adapted to ideology of ruling classes. Forth, we surveyed Korean cartoons which described "true Reality". Newspaper cartoons during imperialism and Min-joong cartoon in 80' period and 2000th period life documentary cartoon, we participated three sector and surveyed each character. Especially, I am dealing with important inconsistency of true reality. As this result, My cartoon enlarge reader's true reality and make "Fun" of recognizing a true reality.

This study's objects are to suggest effective forest community-level management measures by identifying the vulnerable forest vegetation communities types to climate change through a comparative analysis with present forest communities identified and delineated in the Actual Vegetation Map. The methods of this study are to classify the climatic life zones based on the correlative climate-vegetation relationship for each forest vegetation community, the Holdridge Bio-Climate Model was employed. This study confirms relationship between forest vegetation and environmental factors using Pearson's correlation coefficient analysis. Then, the future distribution of forest vegetation are predicted derived factors and present distribution of vegetation by utilizing the multinomial logit model. The vulnerability of forest to climate change was evaluated by identifying the forest community shifts slower than the average velocity of forest moving (VFM) for woody plants, which is assumed to be 0.25 kilometers per year. The major findings in this study are as follows : First, the result of correlative analysis shows that summer precipitation, mean temperature of the coldest month, elevation, soil organic matter contents, and soil acidity (pH) are highly influencing factors to the distribution of forest vegetation. Secondly, the result of the vulnerability assessment employing the assumed velocity of forest moving for woody plants (0.25kmjyear) shows that 54.82% of the forest turned out to be vulnerable to climate change. The sub-alpine vegetations in regions around Mount Jiri and Mount Seorak are predicted to shift the dominance toward Quercus mongolica and Pinus densiflora communities. In the identified vulnerable areas centering the southern and eastern coastal regions, about 8.27% of the Pinus densiflora communities is likely to shift to sub-tropical forest communities, and 3.38% of the Quercus mongolica communities is likely to shift toward Quercus acutissima communities. In the vulnerable areas scattered throughout the country, about 8.84% of the Quercus mongolica communities is likely to shift toward Pinus densiflora communities due to the effects of climate change. The study findings concluded that challenges associated with predicting the future climate using RCM and the assessment of the future vulnerabilities of forest vegetations to climate change are significant.

Nowadays, people start to focus on the value of 'Mindfulness' and 'Slowness', instead of the importance of 'Development' and 'Advancement' in their whole life. According to this background, we attempted to find new research opportunities on User Experience(UX) in usage context of 'Erasing'. Through a interdisciplinary literature review on related works regarding the concept of erasing, we tried to understanding the meaning of erasing within the perspective of philosophy, psychology, and human-computer interaction(HCI). We also conducted the contextual inquiry, one of the qualitative research methods to examine the actual usage context and the user's experience, with 79 users who were required to erase something in three usage contexts, including Paper-Eraser condition, Computer-Keyboard condition, and Tablet PC condition. The results indicate that it is important to provide not only effective erasing but also satisfaction for users in the usage-context of erasing. From these attempts, we expect that our findings will be helpful to understand the meaning of the erasing in academic and practical fields.
