The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

Purpose: For college students, poor eating habits can cause problems with adult health. This study investigated the status of sweet food intake and the degree of stress in college students in the Seoul and Gyeonggi areas to provide a basis for nutrition education by analyzing the relationship between stress and sugar intake. Methods: The subjects were 760 college students, and the survey was conducted using a questionnaire. Statistical analysis for collected data was performed using SPSS (version 21.0). Results: The stress score showed higher stress in female students. Females had more stress in their employment and study-related problems than males. For changes in food intake under stress, the intake was increased greatly in females than in males. For food preference changes before and after stress, males preferred more spicy foods and less salty foods after stress. After stress, females significantly preferred sweeter and spicier foods and less salty, sour, and bitter foods. The intake of sweet foods by stress factors showed that the intake of snacks was higher under the condition of 'worry, fatigue, and tension', and the intake of beverages was increased significantly under the condition of 'anger and aggression'. Conclusion: Sweet foods were preferred under stress, and the amount of intake was increased. Education on food selection and nutrition information should be provided to prevent health problems that can be developed by the reckless intake of sweet foods. Active guidance is needed for college students to select the proper snacks instead of nutritionally insufficient foods to relieve stress.

This study investigates the preferences Chinese have of Korean Kimchi and improvements for Chinese market adaptation of Kimchi through a survey. The questionnaire was conducted on 298 Chinese(108 males, 190 females) residing in Weihai, Yantai and Qingdao in Shandong province. The questionnaire form was developed and used for self-administration. The collected data were analyzed by SAS package. Among the subjects, 88.9% had experienced eating Kimchi and 58.8% liked Kimchi. The preference of Kimchi was significantly higher among males, workers, persons who had visited Korea, and persons interested in Korea compared to females, university students, persons who hadn't visited Korea, and persons with no interest in Korea. The reasons for liking Kimchi, in order of popularity, were for its 'refreshing taste'(64.9%), 'spicy taste'(57.7%), 'chewy texture'(47.2%), and 'sour taste'(35.1%). The reasons for disliking Kimchi were for its 'smell'(19.6%), 'sour taste'(16.2%), 'salty taste'(14.3%), and 'appearance'(8.7%). Of those surveyed, 97.6% had a positive opinion of Kimchi intake in the future. The intention of future consumption of Kimchi was significantly higher in females than males. The type of Kimchi wanted by Chinese was 'less seasoning'(53.4%), 'less spicy'(46.0%), 'sweeter taste'(39.3%), 'less salty'(37.2%), and 'no fish-like smell'(35.6%). Improvements for increasing Chinese Kimchi consumption were 'development of Kimchi according to Chinese preference'(81.2%), 'improvement of sanitation'(73.5%), 'decrease in the sale price of Kimchi'(72.8%), and 'convenient place for the purchase of Kimchi'(63.8%).

Acculturation may manifest dietary behavioral changes of students from overseas. This study investigated the dietary attitudes, food intakes, and dietary behaviors of 121 Chinese college students residing in Busan, Korea. Using a focus group interview and structured survey, subjects were divided into two groups (SG, LG) based on their self-rated acculturation status. The SG (n=70) and LG (n=51) groups consisted of participants that had resided in Korea for shorter than 18 months versus 18 months or longer, respectively. The SG group was more likely to point out the taste of Korean foods as being too sweet, salty, and spicy but less greasy. A food frequency questionnaire was developed to assess normal intake of Korean ethnic, Chinese ethnic, and common foods. The LG group consumed more Korean foods such as rice cake, dried laver, and radish kimchi but less Chinese foods such as bread glue ball and kidney bean. The LG group consumed more salty and fatty foods and Korean liquors, whereas the SG group consumed more fruits and noodles. Based on the exploratory factor analysis, the SG group showed significantly higher scores for "dietary regularity" but lower scores for "indulgence of unhealthful food" factors. In summation, the LG group became more accustomed to Korean foods and adopted less desirable dietary behaviors compared with the SG group. Findings suggest that the residential period of Chinese college students may be associated with their self-rated acculturation status and food acculturation process, and therefore tailored nutrition education programs are needed to support Chinese students' healthier dietary behaviors and food acculturation process.

The purpose of this study was to investigate eating habits and dormitory foodservices' satisfaction in university students using dormitory foodservice in the Jeollabuk-do Iksan area. Self-administered questionnaires were completed by 195 students (86 male, 109 female). Many students (58.5%) ate less than two meals per day and spent around 30 min eating meals. The results show that snack and midnight meals were the main reasons (37.9%) for unhealthy eating habits. Main source of nutritional knowledge and information were TV and the Internet (58.5%), followed by friends and people (25.1%), nutrition books (10.3%), elective courses (4.6%), and newspapers and magazines (1.5%). Men had significantly higher satisfaction scores for nutrition, taste, diversity of menu, as well as hygiene of dormitory food court compared to women (p<0.05). Salty taste was the most important factor in evaluation of taste satisfaction, whereas sour taste was opposite. The reason for taste dissatisfaction in the dormitory food court was not salty enough, and it may be related with their eating habits. The results show that students need education for adequate knowledge and information about the relationship between health and nutrition.

Field studies were conducted with kusabue variety and factorial design of 12 treatments composed of 3 levels, 10 kg, 15 kg and 20 kg of N per 10 a , and 4 levels of 80, 100, 120, and 140 hills per $3.3m^2$ plot in reclaimed slaty area having an average of 0.48% salt concentration. The law of spacing effect was observed in the increase of the number of stems at any application levels of N, and the increased N application exceeding 15 kg N per 10 a did not increase the number of stems in maximum tillering stages. The light recieving efficiency of plant population was greatly reduced by close planting when compared with the effect of increased N applications in heading stage. The spacing effect on the C/F ratio was not noted but was reduced markedly by the increased N applications, accordingly the spacing effect on rough rice yields to the LAI was less than by the increase N application. Closer spacing increased the number of panicle, and non-effective stems, decreased the number of grains per panicle and panicle weight. The increased N applications also increased the number of panicle, reduced the weight of 1,000 grains and the ratio of matured grains. It was recommended to plant 100 hills per $3.3m^2$ with the application of 15 kg N per 10 a in the reclaimed salty area of Korea.

The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well as analyze the differences by gender among fourth to sixth grade students (n=410) in a Chungnam region. Approximately 64% of the students liked the spicy taste of kimchi, 75.9% liked the saltiness, and 48.5% liked well-fermented kimchi. The disliking factors of kimchi were its sour taste (38.5%), strong scent (20.1%), and salty taste (15.4%). The most preferred type of kimchi was Baechukimchi, followed by Kkakduki, Yeolmukimchi, and Chonggakkimchi. Further, the most frequently consumed type of kimchi was Baechukimchi, followed by Kkakduki, Chonggakkimchi and Yeolmukimchi. Oisobaki, welsh onion kimchi, sesame leaf kimchi, Gatkimchi, Nabakkimchi and Baekkimchi were rarely consumed. About 34% of the students consumed 5 to 7 pieces of kimchi per meal, and 84.1% enjoyed eating kimchi, mostly because of its good taste (61.3%). The reason for not eating kimchi was because other side dishes are more delicious (30.2%). About 80% of the students responded that they prepared kimchi at home. Moreover, 74.3% of the students eat kimchi much more at home than at school. Improvements to be made for kimchi at school were as follows: less salty (34.9%), less spicy (27.6%), and sweet (22.5%). In conclusion, students enjoyed eating kimchi because of its good taste. Further, they showed preference for Baechukimchi, Kkakduki, and Yeolmukimchi and consumed them frequently. Because kimchi appears to be more preferred and more frequently consumed, it is necessary to develop a menu using kimchi along with the proper eating guidance for helping students consume various types of kimchi at school or at home.
