This study was examined the preferred temperature and salinity of soup in various demographic groups in order to establish the desirable serving renditions of soup for customers' satisfaction and health. Temperature and salinity were measured in August and November in order to determine the seasonal variation in preference using a digital salinity-temperature measuring device. Four demographic groups totaling 530 were from foodservice establishments in elementary schools(ES: male 68/female 59), middle-high schools(MHS: 62/69), universities(UNIV: 72/67) and companies(COM: 69/64) in Seoul. Various thin or thick soups which are typically served in foodservice establishments were served hot(below $90^{\circ}C$) and warm(below $40^{\circ}C$) in a 50mL portion: salty(1.2%) and less salty(0.4%) at $55{\pm}2^{\circ}C$. The preferred salinities and temperatures of the soups were found to be 0.74%, 0.82%, 0.64% and 0.67% and $49.65^{\circ}C$, $54.24^{\circ}C$, $57.56^{\circ}C$, $58.81^{\circ}C$ for the ES, MHS, UNIV and COM groups, respectively. The preferred temperatures of the soups were increased depending on the age, so the positive correlation was shown between temperature and age. However the preferred salinities of soups were not effected. There was no consistent tendency between men and women in temperature. For salinity, men preferred $0.04{\sim}0.12%$ higher than women in the ES, MHS and UNIV groups. There is no consistent tendency between thin and thick soup in temperature. All groups preferred higher salinity in the thick soup than in the thin soup. Most of the customers preferred a higher temperature and higher salinity in November than in August.

Objectives: The purpose of this study was to examine the economic characteristics of single-person households and explain the effects of them on the food service industry. Methods: For this paper, I analysed the data related with single-person households and the food service industry in two surveys, Household Income and Expenditure Survey and Wholesale and Retail Trade Survey published by Statistics Korea from 2006 to 2015, with an empirical test performed utilizing these data. The indicators of the age of householders, disposable income per capita, and the rate of household of worker were compared between single and multi-person households. Furthermore, sales and the number of establishments in the food service industry were used as industry-variables, and disposable income, eating-out expenses and the rate of single-person households as the household-variables were used in a panel analysis. Results: The results showed that household incomes were lower, age of householder was higher, and the percentage of household of worker was lower in single-person households in contrast to multi-person households. According to the empirical analysis, eating-out expenses of single-person households, in comparison to multi-person households, has significantly positive effects on the growth of the food service industry. This means that the recent trend of increasing numbers of single-person households may help the growth of the food service industry. Conclusions: The growth in the rate of single-person households has been one of the most striking demographic shifts in recent decades. Their economic characteristics and the effects were analyzed to give the managers in the food service industry and the policy-makers useful information in dealing with this new trend. Moreover, in considering the fact that single-person households eat out more frequently than multi-person households, the food service business should develop the managerial strategies focused on acclimatizing to single-person households.

This study examined the preferred salinity levels of soups by different demographic groups in order to establish desirable serving conditions for soups with respect to customer satisfaction and health. The salinity levels were measured in August and November to determine seasonal variations using a digital salinity measuring device. Four demographic groups totaling 1,723 individuals were surveyed from institutional foodservice establishments (IFEs) in elementary schools (ES: male 202/female 194), middle-high schools (MHS: 268/216), universities (UNIV: 208/238), and companies (COM: 182/215) in Seoul. Various thin or thick soups typically offered in foodservice establishments were served salty (1.2%) and less salty (0.4%) at $55{\pm}2^{\circ}C$ in a 50 mL portion. The preferred salinities of the soups were found to be 0.71%, 0.79%, 0.76%, and 0.74% for ES, MHS, UNIV, and COM, respectively. Men had 0.02~0.08% higher preferences than women in ES, MHS and UNIV. The customers also preferred higher salinity levels in November than in August, and in thick soups than in thin soups. The salinities preferred by school children were significantly (p<0.01) lower than those of soups by the IFEs. A similar observation was made for MHS, in which each IFE served the soups with significantly (p<0.01) higher salinities than those preferred by the students. Again, at two COM IFEs, the salinities of the soups served were significantly higher than those preferred by the customers. However, for one of UNIV, the salinity of the served soup was significantly (p<0.05) higher than that preferred by the students, while in the two other UNIV no significant differences were noted between the salinity of the served soup and the level preferred by customers. The surveys showed that 9 out of 12 IFEs served soups having salinities that were significantly higher than those preferred by customers. In particular, regardless of preference, the MHS group was served soups with higher salinity levels than the other demographic groups. The salinities of the soups provided by the IFEs were unnecessarily high for the levels preferred by the customers. Therefore, IFEs should make an effort to serve soups that are less salty soups to enhance public health.

The rapid increase in food borne illness outbreaks in Korea has been one of the major threats to the Nation's Health. Foodservice establishments have been identified as the major place for these outbreaks, mainly due to the lack of sanitary management and sanitary facility management practices. The purposes of the study were to develop hospital foodservice facility evaluation tools, based on the general HACCP-based standards and guidelines, for hospital food service establishments, to ensure the safety of these foodservices and to reduce the risk of food home illness. The scope of this study included: 1) an assessment of the current foodservice sanitation practices and managements for 6 general hospitals, with more than 400 beds, and 3 general hospitals, with less than 400 beds; 2) the development of foodservice establishments sanitation evaluation tools and sanitation standards, based on the HACCP system. The survey data showed varied results between the hospitals surveyed. Most of the hospital foodservice operations had many problems with ventilation and the plumbing. The total dimensional mean scores for the hospitals with more than 400 beds and less than 400 beds were 31.5 and 27.0, respectively. The highest dimension scores were for the water supply facility and lighting, with the lowest for insect and rodent control and toxic materials management. The levels of the mean scores were very low, especially for the general hospitals with less than 400 beds. These low mean scores may have arisen from critical problems within the hospital foodservice operations. The most needed facility management items for improvement were: storage shelf should be spaced 6 inches from the floor and walls, the use of three compartment sinks, utility sinks and cleaning facilities, with a floor drain for cleaning mops or liquid wastes, a ventilation hood designed to prevent dripping onto food, cooking facilities should be disassembled for washing and sanitizing, a separated hand washing sink and a sanitized food board for each area should be provided, all toxic material must have warning labels attached, and be stored in an area away from food preparation under padlock. The evaluation tool consisted of 14 dimensions, with 65 check-off items. The results of this study will provide basic facilities' guidelines to regulators, or foodservice industry personnel, wishing to build, or expend, and establish an efficient flow of food. As a result, food borne illnesses will be effectively prevented, and the Nation's health will be promoted for the development of their own sanitation standards, with a checklist for the safe production of foods.

The study explores the impact of nutritional information on calorie prediction and purchase intent. Administered through self-report questionnaires, the research employs two types of stimuli to assess the influence of nutritional information. Hamburger set images, with or without accompanying nutritional details, were randomly presented to simulate the prevalent mobile app environment for fast-food delivery. Respondents were tasked with predicting calorie content and indicating purchase intent on a Likert 7-point scale. Results show a significant difference in calorie prediction based on the presence of nutritional labeling. While consumers expect positive health effects by estimating more exact calorie information with nutritional labeling, it doesn't significantly influence purchase intent. The study also examines consumer awareness and preferences regarding nutritional labeling policies, emphasizing the need for education and promotion. Most participants recognize the necessity of mandatory nutritional labeling in fast-food establishments, especially through delivery applications, to support healthier choices and prevent obesity.

Foodborne diseases are serious problems throughout the world, because new pathogens have emerged. Nowadays many students eat school lunch provided by school lunch provided by school lunch program. They are threatened by pathogens transmitted by foods. many school children became victims of foodborne diseases. Most foodborne outbreaks were caused by mishandling foods at food service establishments. Food safety practices of school lunch programs in foreign countries were reviewed. Temperature control is the most critical part of keeping the foods safe. In order to prevent foodbrorne diseases in schools, the managers in charge of school lunch program and officials in charge of food safety of local health department try to make sure that foods are out of danger zone of temperature. Prevention of cross contamination, and sanitization of raw foods and utensils are also emphasized by school lunch program managers and health officials.

Effective and systematic sanitation management programs are necessary to prevent foodborne disease outbreaks in school foodservice operations. The purpose of this study was to identify the elements to improve in order to ensure the safety of school food service by evaluating sanitation management practices implemented under HACCP-based programs. The survey was designed to assess the level of hygiene practices of school food service by using an inspection checklist of food hygiene and safety. Fifty-four school foodservice establishments considered as poor sanitation practice groups from two year inspections by Seoul Metropolitan Office of Education were surveyed from September to December in 2005. Inspection checklists consisted of seven categories with 50 checkpoints; facilities and equipment management, personal hygiene, ingredient control, process control, environmental sanitation management, HACCP system and safety management. Surveyed schools scored $68.0{\pm}12.42$ points out of 100 on average. The average score (% of compliance) of each field was 10.7/20 (53.3%) for facilities and equipment management, 7.4/11 (67.2%) for personal hygiene, 7.4/11 (74.1%) for ingredient control, 22.4/32 (69.8%) for process control, 8.9/12 (73.8%) for environmental sanitation management, 4.2/7 (59.7%) for HACCP systems management, and 7.2/8 (89.7%) for safety management, respectively. The field to be improved first was the sanitation control of facilities and equipment. The elements to improve this category were unprofessional consultation for kitchen layout, improper compartment of the kitchen area, lacks of pest control, inadequate water supply, poor ventilation system, and insufficient hand-washing facilities. To elevate the overall performance level of sanitation management, prerequisite programs prior to HACCP plan implementation should be stressed on the school officials, specifically principals, for the integration of the system.
