This thesis is aimed to analyze the importance, satisfaction, perception and intake frequency of fusion menu in order to develop the market segmentations and marketing strategies for useful information on the fusion menu and its improvement in the food industries. The findings of the study are as follows: First, the study revealed that diet menu(low fat, low-cal) and vegetarian menu items have more influence on females than males in regard to the importance of fusion menu when examining gender. Second, the study revealed that Bulgogi pizza, Bulgogi burger, cheese cutlet, cheese kimbab, sweet and sour pork items have great influence on customers in their 10s while green tea latte, rice burger, Bulgogi pizza, kimchi hamburger items have a high effect on customers in their 20s in regard to the perception of fusion menu when examining age. Finally, the study revealed that the taste of food, the cleanliness of vessels, food hygiene, the freshness of food, the quality of menu, the portions of food, the nutrition of food, the speed of food service, food material harmony, the temperature of food, the flavor of food, distinctions from existing food, environment-friendly organic agriculture food material items have maintaining the good performance of fusion menus. It also showed that various strategies for price of fusion menu should be made when examining the IPA analysis.

The present study was performed to obtain data that could be used to popularize yakju(Korean traditional rice wine) by surveying how well rice wine goes with pairing foods. The survey was given to 302 men and women living in the Seoul and Gyunggi areas and work in the food service industry. The Jeon group, Gui group, Jeongol and Jjigae group, Pyeonyuk and Bossam group, and Muchim group were selected as menu items that go well with available rice wines. The survey aimed to identify foods that go well with four rice wines with different sensory characteristics. The survey results showed that both men and women replied that rice wines with Nuruk aroma and Nuruk taste go well with the Jeon group, rice wines with sour and flower aromas and common characteristics go well with the Muchim group, and rice wines with sweet and fruit tastes go well with the Muchim group. However, men and women had different opinions on rice wines having ginseng, soil, and herbal medicine aromas. Men replied that such rice wines go well with grilled meat, whereas women replied that these rice wines go well with Pyeonyuk and Bossan groups.

Electrical Resistance Welding (ERW) on a longitudinal seam-welded pipe has been extensively used in oil and gas pipelines. It is well known that the weld zone commonly suffers from grooving corrosion in ERW pipes. In this paper, the grooving corrosion performances of API X65 grade non-sour service (steel-A) and API X70 grade sour gas resistant (steel-B) steel electrical resistance welding pipelines were evaluated. The microstructure of the bondline is composed of coarse polygonal ferrite grains and several elongated pearlites. The elongated pattern is mainly concentrated in the center of the welded area. The grooving corrosion test and electrochemical polarization test were conducted to study the corrosion behavior of the given materials. A V-shaped corrosion groove was found at the center of the fusion zone in both the steel-A and steel-B ERW pipes, as the corrosion rate of the bondlines is higher than that of the base metal. Furthermore, the higher volume fraction of pearlite at the bondline was responsible for the higher corrosion rate at the bondline of both types of steel.

The sulfide stress corrosion cracking (SSCC) resistance of API X70 grade steel weldment has been studied using SSCC test in NACE TM-O177 method A. Also, microstructures and hardness distribution of weldment was investigated. The microstructure of SAW joint composed ferrite, pearlite and some MA constituent. Instead of hardening in CGHAZ, softening on the HAZ near base metal occurred. The low carbon TMCP type steel used for SAW showed softening behaviour in the HAZ adjacent to base metal, which was known to be closely related with the SOHIC (stress oriented hydrogen induced cracking). The SSC testing revealed that the API X70 SAW weld was suitable for sour service, satisfying the NACE requirements. By suppressing softening in the ICHAZ region, the SSCC resistance of low carbon TMCP steel welded joints could be more improved.

The purpose of this study is to provide the basic findings concerning a quality evaluation. The first conclusion is the coffee's $CO_2$ gas production between a roast brewed at 0 hour and 72 hours after grinding. The espresso, 48 hours after its grind, emits a small amount of $CO_2$ gas, whereas 72 hours after being grinded there is no discharge. In the sensory evaluation, the overall preference is the 72 hours later grind, in accordance to the decrease of the bitter, acid, and sour taste with the increase of the sweet, nutty, and chocolaty flavors. The foam index indicates a significant reduction between the roasts brewed at 0 hour and 72 hours after grinding. A persistence of crema in the Colombian Colombia and Ethiopian Yirgacheffe decline for the 72 hours after its grind coffee. The Tanzanian Kilimanjaro and Brazilian Cerrado roasts show no difference. The pH is decreased in the 72 hours after its grind roast. Moreover, sugar contents in the Colombian Excelso and Brazilian Cerrado are increased, whereas the Tanzanian Kilimanjaro sugar contents are decreased, along with its density.

The purpose of this study was to investigate the quality characteristics of makpyeon prepared with dry milled rice powder. The makpyeon samples prepared with dry milled rice powder and various amount makgeolli (0% (CON), 25% (M25), 50% (M50), 75% (M75), 100% (M100)), and analyzed for moisture content, pH, Hunter's color value, TPA and sensory evaluation. The moisture content did not showed significant difference among makpyeon samples. The L-value, a-value resulted in that CON showed the highest and decreased with the amount of makgeolli. The b-value of makpyeon samples showed that CON was the lowest and increased with the amount of makgeolli. TPA resulted in that M100 showed the highest hardness and the lowest adhesiveness, cohesiveness. Chewiness and gumminess of makpyeon samples were higher than those of CON. Based on quantitative descriptive analysis, the score of brightness, moistness, particle size and gloss of showed higher in CON that in makpyeon samples, firmness increased with the amount of makgeolli. Flavor attributes of liquor odor, sour odor, fermentation odor of makpyeon was stronger in makpyeon samples that in CON with the amount of makgeolli. Acceptance test resulted in makpyeon made with CON, 100% of makgeolli (M100) showed the significantly highest score in taste and overall acceptance.

Elementary schools students'degree of satisfaction on school food service and food preference were surveyed from 352 sixth-grade students in Kwangju and Chonnam area from June 22 to July 3 to enhance the quality of foodservice. The degree of satisfaction was high with cooked rice and soup in terms of temperature and serving state. There were significant differences in the degree of satisfaction depending upon the types of foodservice (p<0.001). There was significant differences in degree of satisfaction for side dishes depending upon the temperature (p<0.05), kinds (p<0.01) and amount (p<0.001). The degree of satisfaction with Kimchi was generally high in the serving state (p<0.05) and the amounts (p<0.01). The degree of satisfaction with desserts were high in the amount (p<0.001). The amount of leftover was high with soup, side dishes, kimchi, cooked rice, and desserts in order. The improvements made on children's behavior after the implementation of the school foodsevice were the adaptation to balanced diet and spending less money on sweets. The factors of influencing the school foodservice and the children's food intake were the education in school (teachers and dietitians) and the health status of their bodies (p<0.001). Children's favorite foods were sweet and sour pork, pork cutlets, oranges, watermelons, and strawberries in order. The least preferred foods were garlic seasoned with soy sauce, raw vegetables of broad bell-flowers, crown daisy greens, and steamed peppers. Children's favorite food types were fried food, desserts, one course meal, and bread. The least preferred types were pickled food, green and seasoned vegetables, cooked rice, and hard-boiled food in order. Generally, the children in the rural area favored most foods compared with those from urban area.
