The purpose of this study was to compare the dietary status of elderly people according to the degree of obesity and mid-arm circumference in order to provide individualized and efficient nutrition management according to the physical condition of the elderly. Among the total 328 subjects, 72.2% were female, and the mean age and body mass index of the subjects were 76.5 years and $23.4kg/m^2$, respectively. The distribution of obesity degree was 47.9% for the normal group, 23.5% for the overweight group, and 28.7% for the obesity group. The distribution of mid-arm circumference was 18.0% for the under-21 cm group, 37.2% for the 21~22 cm group, and 44.8% for the over-22 cm group. About 82.9% of the subjects were consumed at least three meals a day, and 67.8% of the subjects regularly ate alone. The responses for meal time, regular meal, and meal reduction for 3 months were highest in the 10~20 min. (43.4%), yes (79.3%), and no (58.5%) group, respectively. The responses for eating alone were significantly highest in the overweight group (97.4%), followed by the normal group and obesity group according to the degree of obesity (P<0.05). There were no significant differences in preference for five flavors according to the degree of obesity and mid-arm circumference. Among the dietary habits, 31.1% of all subjects ate milk and dairy products more than once a day, and the response for eating vegetables and fruits more than three times a day was highest in the over-22 cm group (61.9%) while the drinking rate was highest in the under-21 cm group (27.1%; P<0.05). In conclusion, the degree of obesity was related to eating ability, and mid-arm the circumference was related with fruit and vegetable consumption and drinking rate.

The purpose of this study is to investigate the dietary life status according to smart device use among university students. In 2015, data was collected during a 3 month survey of the eating behaviors, lifestyles, eating habits, and use of smart devices of 550 university students, as well as their dependency on smartphones. Ultimately, 520 subjects (94.5% analysis rate) were divided into three groups based on their daily use time of smart device: low-use group (<4.7 hours, n=173), medium-use group (${\geq}4.7hours$ and <6.4 hours, n=174), and high-use group (${\geq}6.4hours$, n=173). The more frequent use groups showed a higher level of dependency on the smartphone. Breakfast was found to be the most commonly skipped meal; and the high-use group showed a higher response of irregular meals than low-use group. In assessment of eating habits, the subjects with less smart device usage ate more regularly and at fixed times, did not overeat, drank milk everyday, and did not consume processed food as often. To sum up, more irregularity of meal and undesirable eating habits were found among university students with higher use of smart devices. These results suggest that a control of smart device usage would lead to a more desirable dietary life in university students.

Mongolian horses are one of the oldest horse breeds, and are very important livestock in Mongolia as they are used in various fields such as transportation, food (milk, meat), and horse racing. In addition, research and preservation on pure Mongolian breeds are being promoted under the implementation of the new Genetics of Livestock Resources' act in Mongolia. However, despite the implementation of this act, genetic research on Mongolian horses using microsatellites (MS) has not progressed enough. Therefore, this study was conducted to analyze the genetic polymorphism of five breeds (Gobi shankh, Tes, Gal shar, Darkhad, and Undurshil) using 14 MS markers recommended by International Society for Animal Genetics (ISAG). The mean number of alleles (MNA) was 8.29, expected heterozygosity frequency (H_Exp) was 0.767, observed heterozygosity frequency (H_Obs) was 0.752, and polymorphism information content (PIC) was 0.729. The Nei's genetic distance analysis showed that the genetic distance between Gobi shankh and Darkhad horses was the farthest, and the other three breeds, Tes, Gal shar, and Undurshil were found to be close to each other. Similarly, the principal coordinate analysis (PCoA) and factorial correspondence analysis (FCA) showed that the Gobi shankh and Darkhad horses were genetically distinct from other breeds. On the other hand, it appears that Tes, Gal shar, and Undurshil horses, which are genetically similar, most likely interbred with each other. Therefore, it is expected that these results will help the conservation of genetic resources in Mongolia and the establishment of policies related to Mongolian horses.

This paper describes how location influences on the development of dairy farming. It compares Chuncheon, which in the mountains, Daejeon, which is a transportation center and on flat ground, and Incheon, which is the gate to Seoul and an industrial city. The results analyzed are summarized as follows : 1. Incheon, due to her vast market, influenced strongly on the development of management. But shortage of roughage for feeds is the critical problem there. 2. Owing to the side job of raising chicks, which involves 92% of dairy farmers there, Chuncheon does not make smooth utilization of vast grass pasture. 3. In Daejeon's case, running orchards concurrently is the problem. 4. There exists no gap in wages between the region. The labor supply is most affluent in Incheon and there is competition with other forms of agriculture in the mountainous area. 5. The full-time employee tends to be skillful in accordance with his career. Family labor has been skillful, but the full-time employee is very fluid and shows varieties of skill. 6. Because of the obscurity of the distribution of labor with other jobs in Chuncheon and Daejeon, many unspecialized men serve. 7. The prices of milk are different in each region. The income of dairy farmers is strongly influenced by the low purchasing price of milk plants, and this is one of the important factors hindering the development of dairy farm ing in Chuncheon.

Purpose - This is a comparative study of the market development and characteristics of Ulsan in South Korea, Fukuoka in Japan, and Yanji in China, which are major East Sea Rim cities with adjacent areas of similar natural characteristics of the sea and the country. Particularly, it considers these aspects while focusing on the evolution of networks that appear in the distribution system and at the same time examining the institutions of market activation and regulations that are handled by the central and the local government and the changing logistics due to the development of transportation and the concern of food safety, using a meso-analysis approach. Research design, data, and methodology - The study used a historical and comparative approach with a focus on case studies. It made use of various materials such as local newspaper articles, reports, literature, interviews with experts, discussions with local merchants, discussions with customers, and so forth. Results - In the case of Fukuoka, from the 1960s, due to the entry of supermarkets, supermarkets expanded and they have now come to a dominant market position in the current market. They offer a convenient and comfortable environment while providing a large mall offering a variety of educational and cultural activities for customers to meet the customers' needs, such as the preferences of Korean tourists, who appear to prefer Japanese foods. The Fukuoka City Central Wholesale Market has been exporting fruits and vegetables as well as seafood products to Korea, China, and so forth. In the case of Ulsan, as in the early 2000s, due to the expansion of supermarkets, the traditional markets have been shrinking and further, the modernization of traditional markets was conducted under the auspices of the Small Business Administration. In addition to the large discount malls, the expansion of SSM is expected to further drive the small trader bay. Shopping malls, department stores, and traditional markets contend with each other in Yanji, China, but a large number of citizens appear to prefer traditional markets and imported milk in the supermarket after the melamine scandal in China. Recently, the WanYuan (萬源) wholesale market has been partially completed and made an attempt to become a logistics hub in Northeast Asia. Conclusions - For the development of Korea's retail industry, it is important to offer the government with proposals regarding desired regulation. On the other hand, in order to enable the business of traditional markets, it requires an association for cultural tourism. At present, it would be better to provide a venture fund for the youth rather than infrastructure support. This study emphasizes the importance of institutions and policy to develop networks in the East Sea Rim. Future studies should conduct a survey on customers, managers, and merchants more carefully and systematically to understand the market situation while considering the size of the city and its evolution of markets, as well as policies and institutions.

Increasing sugar intake of population has become a nutritional issue in Korea. Sweet taste perception may be related to behaviors such as eating sweet food including high sugars and total sugar intake. This study aimed to evaluate objective and subjective sweet taste perception and the association among objective sweet taste perception, dietary behaviors related to eating sweet snack food including high sugar, and total sugar intake from the snacks. Participants were 261 healthy female college students (mean age: $21.0{\pm}1.6years$), who were divided into three subgroups based on oral sweet taste evaluation using a sweet taste assessment tool provided by Ministry of Food and Drug Safety: sweet-seeker group (n=139), medium sweet-seeker group (n=54), and unsweet-seeker group (n=68). There was no significant difference in weight and body mass index (BMI) among the three groups; however, the sweet-seeker group had significantly higher sweet taste preference than that of the other groups. Though more people in the sweet-seeker group thought they tended to eat sweet foods than the medium sweet-seeker and unsweet-seeker groups, over half of the sweet-seekers did not think they tended to eat sweet foods. The sweet-seeker group was more likely to eat sweet snacks such as breads, chocolate products, sugar-sweetened milk, and so on than the unsweet-seeker group. Total sugar intake from the selected sweet snacks was 44.4 g for the sweet-seeker group, 34.4 g for the medium sweet-seeker group, and 28.0 g for the unsweet-seeker group with a significant difference. These results indicated the absence of relationship between objective sweet taste perception and the obesity index; however, significant associations were detected among objective sweet taste perception, eating sweet snacks and total sugar intake from the snacks. We also found high disagreement between objective and subjective sweet taste perception of the subjects. The present study provided the novel insight that measuring objective sweet taste perception may be useful for assessing the risk of high sugar consumption and undesirable dietary behaviors.

The recommended meal composition allows the general people to organize meals using the number of intakes of foods from each of six food groups (grains, meat·fish·eggs·beans, vegetables, fruits, milk·dairy products and oils·sugars) to meet Dietary Reference Intakes for Koreans (KDRIs) without calculating complex nutritional values. Through an integrated analysis of data from the 6th to 7th Korean National Health and Nutrition Examination Surveys (2013-2018), representative foods for each food group were selected, and the amounts of representative foods per person were derived based on energy. Based on the EER by age and gender from the KDRIs, a total of 12 kinds of diets were suggested by differentiating meal compositions by age (aged 1-2, 3-5, 6-11, 12-18, 19-64, 65-74 and ≥ 75 years) and gender. The 2020 Food Balance Wheel included the 6th food group of oils and sugars to raise public awareness and avoid confusion in the practical utilization of the model by industries or individuals in reducing the consistent increasing intakes of oils and sugars. To promote the everyday use of the Food Balance Wheel and recommended meal compositions among the general public, the poster of the Food Balance Wheel was created in five languages (Korean, English, Japanese, Vietnamese and Chinese) along with card news. A survey was conducted to provide a basis for categorizing nutritional problems by life cycles and developing customized web-based messages to the public. Based on survey results two types of card news were produced for the general public and youth. Additionally, the educational program was developed through a series of processes, such as prioritization of educational topics, setting educational goals for each stage, creation of a detailed educational system chart and teaching-learning plans for the development of educational materials and media.
