In Korea, sesame oil has been used as a flavor source mainly by edible oil since ancient times, and it has been used by domestic screw pressing. In the 1960's, the demand for edible oils and fats increased significantly due to the improvement of national income and changes in food consumption patterns. In the early 1970's, a few edible oil manufacturing companies with modern solvent extraction and refining plants were established. In Korea, edible oil manufacturers account for more than 85% of employees with 50 or fewer employees. In Korea, there is a very shortage of raw materials for edible oils and fats, domestic production of edible oil is decreasing year by year and import volume is continuously increasing. While importing the edible oil bearing ingredients including soybean and extracted oil in the past, recently mainly imports crude oil and refines it in Korea. Soybean oil, palm oil and tallow account for 70~90% of total imported edible oils. Due to the recent well-being trend, the demand for olive, canola and grapeseed oils as household edible oil has increased and the production of blended oil has been greatly increased. Since the late 1980's, people have recognized edible oil and fat as a food instead of seasoning ingredient and have increased their edible oil and fat intake in Korea. Since the early 2000's, refined oil and fat products produced in Korea have been exported and is increasing every year.

A survey of consumer awareness and attitudes was conducted about genetically modified (GM) foods and the labeling regulations. The questionnaires were distributed to 4,620 consumers who lived in a variety of areas in Korea, and 4,076 people responded. The consumers were asked about knowledge, labeling information, and the source of obtaining information about GM foods. More than 11.5% of the consumers had never heard about GM foods and 86.9% of consumers had less than a normal level of knowledge about GM foods. No statistically significant relationship was found between genders, but the teachers group had moderate knowledge (p<0.001). In total, 28.4% of consumers did not know the GMO labeling regulations. They answered that the reason to buy GM food was do not know>nothing wrong>create benefit>think as safe>inexpensive. The answers to the question of what was the first benefit were: solve food shortage>functional and nutritious food>cultivate in bad condition>nothing>various cultivars. They answered that the worst factor was the next generation effect>environmental disruption. Regarding the development of GM food in Korea, males answered do not know>stronglyrecommend>defer>strongly suppress. Female answered: don't know>defer>strongly recommend>strongly suppress. More than half of the respondents did not have much information about GM foods; 88.3% of respondents answered they did not have educational experience about GM food.

Global meat consumption is increasing worldwide, however, supply remains lacking. Several alternative protein sources, such as cultured meat, plant-based protein production, and edible insects, have been proposed to overcome this shortage. Interestingly, edible insects are characterized by superior digestive and absorptive qualities that make them the ideal replacement for traditional protein production. This study aims to further the processing ability of insect protein by investigating the effects of various pre-treatment methods, such as blanching (HB), roasting (HR), and superheated steam (HS), on the nutritional properties and physicochemical characteristics of proteins extracted from Hermetia illucens larvae. The drying rate, pH value, color analysis, amino and fatty acid profile, as well as bulk density, shear force, and rehydration ratios of the above pre-treatment methods, were explored. HS was found to have the highest drying rate and pH value analysis showed that HB and HS samples have significantly higher values compared to the other modalities. Raw edible insects had the highest value in the sum of essential amino acid (EAA) and EAA index when compared to EAAs. HB and HS showed significantly lower bulk density results, and HS showed the highest shear force and the highest value in rehydration ratio, regardless of immersion time. Therefore, taking the above results together, it was found that blanching and superheated steam blanching pre-treatment were the most effective methods to improve the processing properties of H. illucens after hot-air drying.

The objectives of this study were to: (a) examine the overall operating conditions of both government-dominant and non-governmental food bank programs, (b) understand the operational management attributes on the target based on IPA (importance performance analysis) (c) analyze the present status of donating management, and (d) suggest a direction based on the analysis of advantages and disadvantages of food banks in each part. The random samples of 120 food bank operators were selected by a proportionate stratified random sampling method. A total of 60 government-dominant food banks and 25 non-governmental food banks were analyzed. The main results of this study were as follows: Accord-ing to the Importance-Performance Analysis of operational management, 'assistance for operating funds' and 'deployment of experience staff' were placed at 'Focus Here'. There was a great shortage of experienced staff with food bank-specific knowledge. The average number of the government-dominant and non-governmental food bank program employees was 0.29 and 0.30 respectively, while the ratios of employees with other jobs were 0.96 and 0.83 respectively. Shortages of refrigeration facilities were an area that needs to be addressed. While 51.6% of donated food required cold storage, only 45% of government-dominant and 60% of non-governmental food bank programs had refrigeration facilities. Most of food bank operators (96.3%) were required to visit the donators' locations to pick up the donated foods. And the foods were distributed to the people in need, especially to the livelihood protectee.

With increases in senior citizens and changes in family structure, the need for long-term care system for elderly is increasing, however, the capacity and environment of Korean facilities are very limited. Health and nutritional status of long-term care residents are worse than free-living elderly. In this study, general food service management and health care practices in long-term care systems were investigated. Questionnaire were sent to the directors of all 162 long-term care facilities in Korea and 81 returned the complete answers. The results showed 1) There are slow but steady increase in long-term care systems in Korea, however, the capacity is far from adequate. Less than 10,000 elderly were resided in the facilities. Most of the systems were free-nursing homes and supported by the goverment. Staffing structure revealed that most of the facilities had a director, a secretary, nurses, but only 21% of the systerm hired a dietitian. It showed the shortage of nurses, physical therapists, and dietitians. Therefore, food purchasing, menu planning, food delivery, and the other food service management processes are handled by non-professionals, such as director, secretary, or cooks. Modified fool frequency questionnaire were used to get the frequencies of each food items used in menu and a menu-analysis was made on the one-day menu provided by the facilities. The results showed relatively satisfactory in nutrients content and food frequencies., however, this was about what was used in menu, not what was eaten by the residents. Therefore this results did not tell that the food intake status of individuals. In most facilities general health checkup was done on a regular basis, and had residents with various chronic degenerative diseases, such as hypertension, neuralgia, stroke, arthritis, diabetes. But the items checked on health checkup included weight, height, blood and urine tests, X-ray test, which suggested that the checkup lists should be revised to accomodate the health problem of the aged today.

The purpose of this research was to analyze the job satisfaction and business attitudes of restaurant owners in order to explore solutions for improving restaurant management. The results were as follows : 1) The motive for starting a restaurant business was vocational aptitude \longrightarrow possibilities \longrightarrow good income : 2) In terms of job satisfaction, most respondents were satisfied with both the work itself and the income. It was also observed that the younger owners were more satisfied with their jobs than the older owners : 3) Increased costs, including labor and food costs, was indicated as the biggest problem in restaurant management. Respondents also perceived labor shortage as one of the most difficult problems. Men were more likely than women to consider the following problems as being more serious: rent, financial problems, taxes, regulation restrictions, menu development and customer complaints. It was found that as the size of the restaurants grew, the respondents perceived the shortage of labor as the hardest part of running a business : 4) Respondents agreed that employing good foodservice workers was the most important part of foodservice management. Owners also believed that they needed more research time for menu and service development 5) To be successful, the restaurant owners paid the most careful attention to food taste. Service, sanitation, and menu development were also emphasized. Respondents stressed the focus on service, good relationships, diligence, and faithfulness in order to be a good restaurant owner. The results of this research suggest that restaurant owners should have more professional conscientiousness to succeed in their own businesses, as well as improve the quality of the foodservice industry. Other important aspects related to the overall improved quality of the foodservice industry are: the continuation of government support, the enlargement of educational opportunities and greater respect for foodservice employees.

Northern corn leaf blight caused by Exserohilum turcicum Pass is considered the most important disease infecting corn (Zea mays L.) in the Peoples' Republic of Korea (North Korea). It contributes to the food shortage in North Korea. The objectives of the current research were to study resistance expression and responses of corn crosses made between ten hybrids from North Korea and inbreeding lines ($S_{3-4}$ stage) from the Republic of Korea (South Korea). The experiments were conducted in six trials with a total of 184 crosses including two commercial hybrids in each trial. The trials were conducted at two locations in North Korea (Mirim and Eunsan) and one location in South Korea (Gunwi) under natural infestation of E. turcicum. Host plant responses were rated on a scale of 1 (highly tolerant) to 9 (highly susceptible). A total of 111 crosses (62.4%) showed significant tolerant or susceptible response variations among three locations; 42 crosses (22.8%) at two locations and 69 crosses (39.0%) at one location, respectively. At least 8 crosses of high level of tolerance and 12 crosses of high level of susceptibility showed significantly different biotic responses (P = 0.05). The results of the current study and historical reviews of E. turcicum epidemics in both North and South Korea suggest that breeding of tolerance with quantitatively inherited genes should be carried out for a sustainable corn production in North Korea.

In order to fad out an efficient way of topdressing nitrogen fertilizer in mulch-cropping system of onion(Allium cepa L.), solid, slow-release, and liquid forms of nitrogen fertilizers were allied to cv. 'Changnyungdaego' various number of times at different time, with 5 topdress applications of solid fertilizer serving as a control. Whole basal application of conventional solid fertilizer and 2 slow-release fertilizers were labor-saving and showed improved storage quality of bulbs, but resulted in poor plant growth and considerably low yield due to fertilizer shortage from early April. This suggests that topdress application is necessary. Liquid form of nitrogen fertilizer was more effective for plant growth and yield and saving labor than the solid form. Early applications was effective for increasing yield and storage quality of onion bulbs harvested. Thus two applications of liquid form of nitrogen fertilizer in February and March at rome month interval are recommended in mulch crowing system of onion.

This study attempted to research the local food of various regions at a personal level by discovering how food has developed das part of a region's culture base. Discovery of the characteristic story behind the making of a region's characteristic food as local delicacies can inspire self-esteem in the culture, and enhance the real-life image as appropriate to a region, and thereby be made a part of local tourism and thus contributing to the local economy. For this reason, the native foods of the region of Chungcheongnam-do were researched in terms of the cultural sensibilities that inform the unique history of that region. The study was designed so as to aid in understanding food's characteristic value in Chungcheongnam-do and to give a historical representation of Chungcheongnam-do's image by means of storytelling techniques; thus, the local food's character can be presented alongside a story that appeals to the five senses. For this purpose, Chungcheongnam-do's representative native rice table was cast as the 'Hyunchoong rice meal table' - after the figure of admiral Yi Sun Shin of Asan area region, a representative image of Chungcheongnam-do - and 'Choosa rice meal table', after the figure of 'Choosa' Kim Jeong Hee of Yesan region, of which various literary works form a representative image of Chungcheongnam-do. 'Hyunchoong rice meal table' was composed of a health food centered menu which could supply sufficient nutrition as a food ration in times of war or winter shortage, thus providing an image of nutrition and power as appropriate to these situations. Also, to assess the health effectiveness of each rice table, the functionality of the ingredients were investigated as reported in 'Sik-ryo-chan-yo : a dietary treatment' which was published by Soon-Ui Cheon in the Chosun era and by which the foods of the early Chosun era won recognition as being both healthy profitable.
