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.

Experimental studies for an indirect R404A-$CO_2$ refrigeration system and a direct R404A refrigeration system were conducted. The configurations of the indirect R404A-$CO_2$ refrigeration system are a R404A refrigeration system as a top cycle and a circulating $CO_2$ system as a bottom cycle. The direct R404A system was modified from indirect R404A-$CO_2$ refrigeration system by removing circuit for $CO_2$ circulation. Various tests for both systems were conducted by changing load side brine temperature from 0 to 5 and $10^{\circ}C$ with cooling brine temperatures for R404A system at 15, 20, or $25^{\circ}C$. The indirect R404A-$CO_2$ refrigeration system showed the highest COP when load side brine temperature was at $10^{\circ}C$ in the evaporator and at cooling brine temperature of $15^{\circ}C$. The COP of 3.04 under that condition was the highest. This indirect R404A-$CO_2$ refrigeration system showed 9.02% higher COP than the direct R404A system that had increased pipeline length of 15 m, which simulated actual installation in a supermarket.

The purpose of this study is to figure out the urban low-income consumers' present possesion condition of electric appliances, the way of purchasing, shopping scope of groceries and electric appliances, and the shopping scope and information seeking behavior of groceries and electric appliances according to the socioeconomic variables, and the shopping scope of electric appliances according to the way of paying price. For this purpose 129 low-income consumers living in Inchon were interviewed through questionnares. Finally 100 questionnares were analyzed. The first major of this study is that the possesion rates of color television set and refrigerator are comparativelyl high, while those of washing machine, record player and camera are low. In case of electric appliances, consumers usually purchase things on credit and as a shopping place, they usually go to a commercial agent. In case of groceries, they usually buy things for cash, and in case of one price labeled groceries they usually buy things at a supermarket. Second, according to the way of paying price, the shopping scope of some electric appliances is broader in case of purchase for cach than in case of purchase on credit. Third, the shopping scope and information seeking behavior classified by the socioeconomic variables according to the income, age and education. That is as the income and education become higher and the age becomes lower, the shopping scope becomes broader, mass media information source is much more uaed and the frequency of seeking becomes higher. Through this study, I would like to suggest the followings. (1) The problem of low-income consumers is closely connected with the low education level, so it can be solved a bit through consumer education. (2) Especially the consumers' problem is more serious in case of those who are aged and get very low income and education. Therefore special attention is needed to those consumers.

Recently great loss of life and property is occurring because of fire, natural disaster, earth quake, tsunami and so on. People spend 80~90% of their time indoor environment like office, supermarket, campus. Therefore Indoor navigation and guidelines system became so essential for most of all. Incase of emergency we must be careful earlier, in such a cases 5G kind of new technology may also cannot work. So immediate action and quick routing notification for guidelines and protection is the most. Considering this issue We proposed indoor evacuating guidance system based on microcontroller Wi-Fi board for Indoor APP using mobile. Focusing various kind of technology like, ok google, voice search APP we purposed node architecture based system. When we listen fire alarm while living inside the room. Then to be safe we connect with server and start Arduino UNO+IoT ESP8266 Wi-Fi shield version1-IoT module to store data in MySQL DB server. We make application to escape out from the building up-to the three exits giving information from source point to destination. Our program can send information to the users emergency location and situations. For this when the user get sound or vibration in their mobile device it indicate fire out near by. At that time we update message from Arduino to DB server for the fixed current position inside the building which give routing signal for that fire out location by changing values from 0 to 1. We have user in point 10 where user is near by. Later we detect Wi-Fi signal form Nodemcu as room of each floor and try to connect with user. Main purpose of this paper is to save life of people in short time and find out the shortest path up to nearest exits in the time of emergencies and rescue them.

Survey the intake of carbonated beverage and the perception of carbonated beverage was conducted with 422 middle school students in Daegu area to clarify attitudes toward carbonated beverages and their consumption in adolescents. Statistical data analysis was done using SPSS version 12.0. Of all subjects, 31.3% preferred carbonated beverage among all beverages consumed, and preference for flavored carbonated beverage was highest (42.2%). Students who liked to drink carbonated beverage spent more money in snacks out of their allowance; frequency of carbonated beverage consumption correlated with amount of allowance (p<0.05). Carbonated beverage was mainly consumed with fast-food (61.5%), and 53.3% of the students purchased the beverages at supermarket. The majority of middle school students (30.4%) drank carbonated beverage more than 3~5 times a week, which was high frequency of carbonated beverage consumption. Preference and consumption frequency beverages differed significantly with knowledge level (p<0.01). Of the subjects, 73.2% drank carbonated beverage without checking nutrient contents, and those with low knowledge level of carbonated beverage neither read the label on nutrients nor were interested in nutrition education (p<0.05). The results underscore the need to provide systematic nutrition education at home and in school to prevent excessive intake of carbonated beverage and to help adolescents choose healthy beverage during a time in life when growth is especially prominent.

Distribution structure is the link between a society's needs and its industrial responses. A change in distribution structure brings about a consumption structure which may results in considerable changes in lifestyle including food habits. The purpose of this study was to evaluate a effect of change of distribution structure on the food purchase. The survey was carried from May to June, 1997 by way of questionnaire of 407 housewives, aged 23-64 years, in Seoul and the capital area. The questionaire consists of sociodemographic characteristics of the subjects and distribution channel, information route of food selection, acknowledgement and coefficient of utilization of new distribution channel, mainly used distribution channel in food purchase, important factors in food selection, and food purchasing behavior. Their data were statistically analyzed based on frequency, mean, and $X^2-test$. The major findings of this study were as follows; 1) Most frequently used distribution channels in food purchase were supermarket(38.53%), department store(15.23%), discount store(14.05%), a conventional retail market(13.87%), membership wholesale club(8.07%), and a conventional wholesale market(6.53%). 2) The new distribution channels that subjects have ever used were discount store(75.4% of the subject), membership wholesale club(63%), mail order house(32%), outlet store(29.4%), home shopping(10.3%). 3) Compared to the subject living far from the new distribution channel, the subject living close to the new distribution channel was higher in frequency of new distribution channel utilization. These observations suggest that change of the distribution structure promotes the change of the food purchasing behavior.

Aim of this study is to investigate the perception and purchasing status of functional beverages for adults in the Chungnam area. In this case, the reasons to buy the functional beverages for men were 'recovery of fatigue (43.1%)', 'quenching thirst (21.6%)', 'health promotion (19.6%)', 'supply of nutrition (15%)', and 'a loss in weight (7%)'. Otherwise the reasons to buy the functional beverage for women showed to be 'recovery of fatigue (28.6%)', 'health promotion (26.4%)', 'quenching thirst (22.1%)', 'supply of nutrition (12.9%)', and 'a loss in weight (10%)', which were significant different between the men and women subjects. The place to buy functional beverages was for singles (46.5%) a store and for married person a supermarket. The purchase of functional beverages was affected by as follows; manufactured date > original granule > nutrition sign > country > price > taste > brand > scent > color and the women are affected more than men. For functional beverages, the men preferred to buy an energy drink and vitamin drink more than the women. After the intake of functional beverages, the men and women recognized the effect on 'recovery of fatigue' and 'a loss of weight/release of a feeling of hunger/improvement of constipation', respectively. Considering the results of the study, it is necessary to clarify the function of functional beverages so that consumers can choose and take the correct functional beverage by themselves. In addition, the nutritional education should be conducted for the intake allowance for the compositions and excessive or inadequate intake of functional beverages.

Studies focusing on the constantly changing buying behavior and product preferences of a booming teen market are rare and this is particularly true in the Philippines. To address this gap in the literature, this study focused on the supermarket brands of cologne preferred by teens in the Philippines such as Lewis & Pearl (L&P), Johnson's Baby Cologne, Juicy, Bench, Ellips, Fiona, Bambini and Baby Flo which are manufactured by various competing companies. Essentially, this study presented and described the profile and buying behavior of cologne users and non-cologne users and determined whether preferential differences existed between these brands. The respondents consisted of 473 teens all over the Philippines stratified in terms of general location via the three major groups of islands in the Philippines: Luzon, Visayas and Mindanao. Respondents came from selected schools in Quezon City in Metro Manila, Sariaya in Quezon Province, Cebu City, and Digos City to represent the Greater Metro Manila Area, Luzon, Visayas and Mindanao, respectively. Findings showed that almost all of the respondents used cologne at varying degrees. In general, teens use several scents and brands of cologne and continually shift from one scent/brand to another scent/brand. This made it difficult for any company to capture loyal consumers. The most popular brands used by teenagers were Bench (61.7%), Lewis and Pearl (59%), Juicy (42%), Afficionado (32%), Fiona (19.3%), Penshoppe (18%), Bambini (12.6%), Ellips (11.3%) and Zen Zest (7.5%). Fragrance or scent is the top priority of teenagers in choosing a cologne brand, followed by brand name, affordability, bottle design and endorser. The spray bottle type of colognes is preferred even if cologne spray bottles are priced higher than the splash cologne bottle type. Managerial implications of these findings for market players, marketing scholars and prospective investors are presented.
