This study was to investigate consumers' recognition, knowledge and purchase attitude on genetically modified(GM) foods in Daejeon area. Data of 283 questionnaires were analyzed by using the SPSS(Ver. 17.0)program. Most of the subjects were women (91.9%), distributed 30's(41.7%) or 40's(31.8%), and graduated from university(41.3%). The kinds of GM foods that many subjects had known were soybean, corn, tomatoes and potatoes. The subjects answered that there were GM foods in supermarket items were 71%. Consumers' recognition on the safety of GM foods was 'somewhat anxious'(65.4%). After confirming which their purchasing item is GM foods, 'they will buy it case by case'(60.1%) or 'they will never buy it'(27.9%). The most reason of never buying GM foods was 'harmful to health'(82.3%). The first reliable information sources on GM foods were medical institutes and professionals. The knowledges about GM foods were significantly higher in 20's and 'less than 1year' of marriage duration than the other groups(p<0.05). On the purchase attitude of GM foods, the 20's responded favorably compared to other groups (p<0.01). Subjects' opinion on the necessity of development on GM foods tended to higher in 40's and 'less than 2 million won' of monthly income than the other groups. For the reason about necessity of it's development, 'nutritional, functionality and quality improvement' was 53.7%. In conclusion, many consumers regard that GM foods is not yet safe for health. Accordingly, government and research institutes should examine thoroughly and research continuously for the safety of GM foods. They must announce to consumers accurate information about GM foods.

The contemporary consumers have insatiable desires for material and outward appearance. In terms of the desire for outward appearance, people recognize that a beautiful outward appearance can be made by an artificial effort. Subsequently, the interest in a beauty and fashion has been increased. In addition, a cable TV shows a beauty and fashion program targeted for women in 20s to 30s. This study tried to examine the stories on experience of consumption by consumers watching a beauty and fashion program in a women specialized channel of a cable TV. The total number of narrators who participated in this study was 11. Among them, we formed 26 narrative plots on the basis of interviews for 7 persons who could use Labov's structural analysis. The result of analyzing narrators' narrative plots was as follows: First, although narrators received the information on beauty and fashion through a channel which became the target of this study, they applied such information into an ordinary life by transforming such information. Second, narrators thought that their confidence and superiority could be expressed through a beauty and fashion. Third, narrators' consuming life showed a showing off-type consumption and an objective consumption. Fourth, narrators have a gap between the behavior orientation and real actions. And they experiences various trobles on consumption life. Fifth, through the interview for narrators, a trend of reconsidering their consuming life was found out.

The aim of this study was to use the information deduced from biotopemap in Boryeong, Chungnam province conducted in 2011 and to select the wildlife survey point. The information used for the study was deduced from the knowledge and experience of wildlife specialists and was realized by 6 environmental variables (Outside distance from food vegetation, Outside distance from farm land, Outside distance from forest, Human density, Outside distance from road, Outside distance from water). 6 environmental variables were modeled by map overlay method and the model could deduce the correlation of 94.72% as a result of comparing with occurrence information. The areas predicted to have many occurrences were rural landscapes, forests, and valleys, and they can be used to deduce the quality wildlife survey results in the limit of survey range (area, schedule, and budget). However, it had the limit points such as the inside of forests was excluded, all species did not prefer the same habitat. The following studies are needed for this part in the future.

The purpose of the study lied on supporting the reeducation program which was focused on the demand with the clients by analyzing the recognition on the real situations of the reeducation on the hair designers in the nation. As a result on the subject, the responders said they could usually learn new information through the various seminars that were held by beauty product suppliers and companies, and most of the high school or under high school level designers have participated in various seminars while the designers who graduated from a junior college or universities had experienced new trends at life time education establishments(p<0.01). A hair designer who was single and paid low salary usually depended on the course inside the shop(p<0.01), and most of the information they got was through the suppliers of the beauty products. In that case, regular sources of information, such as educational establishments, informative magazines, Internet were highly recommended. A reason for unsatisfactory reeducation was due to lack of time and a reason for not participating the seminar was also due to time shortage caused by regular working hours, which was reflecting the real situation of the hair designers. As a suggestion for the reeducation establishment, most of the responders wanted vocational schools or life-time educational center. They wanted a fixed regular period for reeducation, especially over the weekend for after working hours. It means they want long-time systematic education. Considering the results, a course which is organized for a long-time systematic purpose is suggested for the hair dressers who want to be professionals in the field with the class equipped with contents of the classes, period, and place. For the purpose to be realized, improvement of the working hours in needed and it will be an incentive to make the hair designers satisfied with their work.

The purposes of this study were to research the behavior of consumption and needs about the female university students to provide useful information which would help finding the marketing source of cosmeceuticals. The sample was consisted of 464 female university students who had experiences of using the cosmeceuticals. Data were analyzed by factor analysis, frequency, x2-test, t-test, ANOVA(LSD) using SPSSWIN. The results were as follows: When the female university students purchased the cosmeceuticals, they considered the effectiveness and the price, so were satisfied with good effect and low price. The most important marketing methods in cosmeceuticals for female university students were through the internet and mail order shopping. Whereas, demerit factors of internet shopping were founded to be the complexity of exchange or refund and the little chance of free samples for trial. The good marketing strategies might be sending trial samples, future payment system after trial period, and/or supporting the event held in the university. Besides, it might be a consideration to have an event for the improvement by public trial. Anti-aging cosmeceutical was the most preferred item for female students, sun protection and whitening cosmetics next in order. Therefore, a target customer for cosmeceuticals might be lowered in age. The purchasing cost system and therapeutic effect of cosmeceuticals had to be developed for 20's. It was necessary to be safe and effective. The factors affecting the level of satisfaction for cosmeceuticals could be categorized into 4; market environment, simplicity of purchase, product merit and additional service. The needs for cosmeceuticals showed significant differences according to grade and kinds of product.

The purpose of this study was to analyze potential effects of Koreans' ultraviolet risk awareness and appearance management on their UV protective behaviors in daily life and outdoor activities, and was to investigate in their awareness of UV-protective clothing and their purchase attitudes toward anti-UV protective clothing. To meet the above goals, we have surveyed a total of 262 participants(male and female) residing in Chungcheong province. Findings were as following: As a part of ultraviolet-protective behaviors, it was found that the respondents often relied on applying sun-block cream or shady place before exposition to sunlight. Particularly, it was notable that 30's or older group was more proactive in UV protective behaviors than younger group below 30 years old. There were significant correlations among the respondents' UV protective behaviors, their awareness of anti-UV clothing and their purchase attitudes to anti-UV clothing. Also, there were also significant correlations among their UV-protective means for outdoor activities. That is, more favorable awareness about anti-UV clothing they have is associated with their more active attitudes to purchasing anti-UV clothing and taking anti-sunlight behaviors. It was found that the number of respondents who used cosmetics for outdoor activities was more than that of respondents who used clothing to protect their body from ultraviolet ray. Hence, it will be necessary for follow-up studies to focus on the development and promotion of anti-UV clothing.

We developed smartphone application and web application server to acquire and effectively manage tree measurement information. Smartphone applications can measure tree height, diameter at breast height (DBH), azimuth, altitude, slope, and positional coordinates using augmented reality (Google AR core) and motion sensors. The web application server effectively manages and stores measurement information. To evaluate the accuracy of information acquired using a smartphone, 90 Korean pine trees (Pinus koraiensis) were randomly selected from a natural mixed forest, with a total of 90 representative trees randomly collected from a natural mixed forest. Then, height and DBH were measured using a Haglof Vertex Laser Hypsometer and caliper. Comparisons of the results indicated significant results at the 95% level and a very high average correlation of 0.972 for both tree height and DBH. In terms of DBH, the average errors were 0.6745 cm and 1.0139 cm for artificial coniferous and natural mixed forests, respectively.

In this study, a technique for estimating water surface velocity fields in the Universal Transverse Mercator coordinate system using the GPS information of a propagating drone but not ground control points is developed. First, we determine the image direction in which the upper side of an image is directed based on the navigation information of the drone. Subsequently, we assign the start and end frames of the video used and determine the analysis range. Using these two frames, we segment the measurement cross-section into a few subsections at regular intervals. At these subsections, we analyze 30 frame images to create spatio-temporal volumes for calculating the velocity fields. The results of the developed method (propagating drone surface image velocimetry) are compared with those of the existing method (hovering drone surface image velocimetry), and relatively good agreement is indicated between both in terms of the velocity fields.

As the risk of biodiversity reduction and extinction becomes serious due to climate change and indiscriminate development, the importance of conservation of the natural environment and ecosystem is increasing. In this situation, Ireviewed that overseas cases of the ecological outlook and evaluation system aimed at providing information on natural resources and ecosystem change. As a results, other countries showed that various research institutes have been carrying on field surveys by classification group, but it was different from us that the investigated data are collected and managed in an integrated manner and repeatedly provided within a short period of time. In addition, it was analyzed that it was highly utilized in policy and environmental impact assessment by providing evaluation-based prediction and outlook information along with basic survey data. Based on this, the limitations of information use in our wildlife surveys and environmental impacts assessments were analyzed, and the estabilishment of a ecology outlook and evaluation system and policy support measures were considered. In addition, based on the proposed outlook and evaluation system preparation plan, a policy direction that can be effectively used in domestic natural ecosystem policies was proposed.

The volume of the party wear market is gradually growing in the Korean fashion market. The study attempted to examine psychological clothing benefits as the criteria for market segmentation, and identify differences in information sources. and clothing evaluative criteria in each segmentated market. The summary of the key findings are as follows. Three segments were identified by psychological clothing benefits: pleasurably self-expressing group, fashion-seeking group, and indifferent group. The differences in search information sources between the classified groups were identified The fashion-seeking group had a higher mean score on mass media. The pleasurably self-expressing group had higher scores on advice from friends, colleagues, or companions. The differences in evaluative criteria between the classified groups were also identified. Among the evaluative criteria, the splendid boldness and polished silhouette criteria showed a marginal difference between each group. This study can contribute as a cornerstone for future studies on party wear and market strategies.
