Rice is 34% of the world's population used as a staple food. But the world population is increasing. Food security is not well protected. Improving cultivar development can address food security. Quantitative trait locus (QTL) mapping is a statistical analysis using both phenotypic and genotypic dates. The purpose of QTL mapping is to determine a gene. Increasing grain size is a way to increase yield in rice. Grain size-related genes were mapped using CNDH population obtained by cross-breeding Cheongcheong (Indica) and Nagdong (Japonica) through anther culture. Grain harvested from experimental field of Kyungpook National University in Gunwi in 2021. Genes related to grain length were detected between RM5964-RM12285, RM20924-RM20967 in chromosome 1, 7. LOD score is 5.88 and 5.6. Genes related to grain width was detected between RM289-RM18130 in chromosome 5. LOD score is 4.57. Genes related to grain length/width ratio were detected between RM5459-RM3482, RM5699-RM1211 and RM3838-RM3381 in chromosome 1, 2, 5. LOD score is 3.75, 3.14 and 3.41. 4 genes was detected in chromosome 1 and 2 genes was detected in chromosome 2 and 7 genes was detected in chromosome 5. 2 genes related to grain shape and quality were detected. 4 genes related to grain length were detected. 4 genes related to grain size were detected. 1 gene related to grain size and weight was detected. 2 genes related to grain length and weight were detected. By finding the gene related to grain size, it provides food to people threatened by food security and solves the food shortage.
A survey of one hospital foodservice system in Seoul was undertaken and detailed in formation was collected from 538 patients. Patient satisfaction with the quality of hospital food and food-related service was evaluated by questionnaire survey. It was measured by assessing 24 variables. The effect of medical treatments, age, length of stay and appetite on patients' satisfaction satisfied with the food served, although the variety of food and seasoning of food received the lowest score. The highest rated items were attitude of personnel serving food, the portion size of cooked rice, and the cleanliness of dishes and tray. Younger patients were significantly less satisfied than were older patients. Female patients were significantly more satisfied nificantly more satisfied than were other patients. Medical treatments, age, length of stay of stay and appetite were found to be significantly correlated with patient satisfaction scores. Foodservice attributes for improvement were taste of meals, selection and variety of food and temperature of food.
A survey of 28 school foodservice establishments in Seoul and Kangnung was undertaken and detailed information was collected from 3,590 elementary school students. Childrert's satisfaction with the quality of school food was evaluated by questionnaires. It was measured by assessing 15 variables. Statistical data analysis was using SAS package program for descriptive analysis and T-test. Elementary schools in Seoul were all located in urban areas, whereas elementary schools in Kangnung were in urban areas (40.4%), provincial areas (40.0%) and in isolated areas (20.0%). Children seemed to be generally satisfied with the food served, with the lowest score of milk. Mean wastes for soups and Kimchi were found to be larger than those for milk and side dishes. The major reasons for leaving leftover were 'dislike the food (27.4%)'>'too big portion size (23.6%)'>'food is not tasty (19.2%)'>'low appetite (17.6%)'>'food is too overcooked or undercooked (3.9%)'>'food is not hot enough (3.2%)' in order.

The satisfaction of elementary school children and their parents with the school lunch program by foodservice system was assessed by questionnaire. The subjects Participated in this survey were 1,136 students, first-6th grade elementary school children and 1,140 parents in Seongnam area. The result was as follows: the satisfaction score for school lunch program by foodservice system was rated as 'high'. Students' and parents' satisfaction score were 3.63 point and 3.62 point (5-point Likert rating scale), respectively. Difference of satisfaction score by grades was that high grade students were significantly lower than low grade students' (P<0.001). Five grade students' score was 3.23 point and 2 grade students' score was 4.04 point. Children's favorite food types were meat, dessert, cooked rice and fried food. The least preferred food types were green and seasoned vegetable, kimchi, soup and fish. Students felt shortage of favorite foods and a lot of dislike foods. Parents answered that thorough sanitary management (22.5%) and use of good quality foodstuffs (11.5%) were the most important factors in improvement of the school lunch program.
This study was performed to investigate the qualities of jelly supplemented with purple sweet potato (C:0 g, P1:1 g, P3:3 g, P5:5 g, P7:7 g). The pH decreased (acidity increased) with the addition of purple sweet potato powder (p<0.01). The sugar content of the jelly also significantly increased when purple sweet potato was added. The DPPH radical scavenging activities of jelly increased as the addition of purple sweet potato increased. As the content of purple sweet potato increased, the L and b values decreased and the "a value" increased. In terms of textural characteristics, the addition of purple sweet potato increased hardness and springiness, while it decreased the cohesiveness. The results of the sensory evaluation showed that the appearance, flavor, taste, texture, and overall acceptability gave the highest score for jelly containing 5 g of purple sweet potato (P5).

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

The endeavors enhancing the grain quality of high-yielding japonica rice were steadily continued during 1980s∼1990s along with the self-sufficiency of rice production and the increasing demands of high-quality rices. During this time, considerably great, progress and success was obtained in development of high-quality japonica cultivars and qualify evaluation techniques including the elucidation of interrelationship between the physicochemical properties of rice grain and the physical or palatability components of cooked rice. In 1990s, some high-quality japonica rice caltivars and special rices adaptable for food processing such as large kernel, chalky endosperm aromatic and colored rices were developed and its objective preference and utility was also examined by a palatability meter, rapid-visco analyzer and texture analyzer. The water uptake rate and the maximum water absorption ratio showed significantly negative correlations with the K/Mg ratio and alkali digestion value(ADV) of milled rice. The rice materials showing the higher amount of hot water absorption exhibited the larger volume expansion of cooked rice. The harder rices with lower moisture content revealed the higher rate of water uptake at twenty minutes after soaking and the higher ratio of maximum water uptake under the room temperature condition. These water uptake characteristics were not associated with the protein and amylose contents of milled rice and the palatability of cooked rice. The water/rice ratio (in w/w basis) for optimum cooking was averaged to 1.52 in dry milled rices (12% wet basis) with varietal range from 1.45 to 1.61 and the expansion ratio of milled rice after proper boiling was average to 2.63(in v/v basis). The major physicochemical components of rice grain associated with the palatability of cooked rice were examined using japonica rice materials showing narrow varietal variation in grain size and shape, alkali digestibility, gel consistency, amylose and protein contents, but considerable difference in appearance and torture of cooked rice. The glossiness or gross palatability score of cooked rice were closely associated with the peak. hot paste and consistency viscosities of viscogram with year difference. The high-quality rice variety “Ilpumbyeo” showed less portion of amylose on the outer layer of milled rice grain and less and slower change in iodine blue value of extracted paste during twenty minutes of boiling. This highly palatable rice also exhibited very fine net structure in outer layer and fine-spongy and well-swollen shape of gelatinized starch granules in inner layer and core of cooked rice kernel compared with the poor palatable rice through image of scanning electronic mcroscope. Gross sensory score of cooked rice could be estimated by multiple linear regression formula, deduced from relationship between rice quality components mentioned above and eating quality of cooked rice, with high Probability of determination. The ${\alpha}$ -amylose-iodine method was adopted for checking the varietal difference in retrogradation of cooked rice. The rice cultivars revealing the relatively slow retrogradation in aged cooked rice were Ilpumbyeo, Chucheongbyeo, Sasanishiki, Jinbubyeo and Koshihikari. A Tongil-type rice, Taebaegbyeo, and a japonica cultivar, Seomjinbyeo, shelved the relatively fast deterioration of cooked rice. Generally, the better rice cultivars in eating quality of cooked rice showed less retrogiadation and much sponginess in cooled cooked rice. Also, the rice varieties exhibiting less retrogradation in cooled cooked rice revealed higher hot viscosity and lower cool viscosity of rice flour in amylogram. The sponginess of cooled cooked rice was closely associated with magnesium content and volume expansion of cooked rice. The hardness-changed ratio of cooked rice by cooling was negatively correlated with solids amount extracted during boiling and volume expansion of cooked rice. The major physicochemical properties of rice grain closely related to the palatability of cooked rice may be directly or indirectly associated with the retrogradation characteristics of cooked rice. The softer gel consistency and lower amylose content in milled rice revealed the higher ratio of popped rice and larger bulk density of popping. The stronger hardness of rice grain showed relatively higher ratio of popping and the more chalky or less translucent rice exhibited the lower ratio of intact popped brown rice. The potassium and magnesium contents of milled rice were negatively associated with gross score of noodle making mixed with wheat flour in half and the better rice for noodle making revealed relatively less amount of solid extraction during boiling. The more volume expansion of batters for making brown rice bread resulted the better loaf formation and more springiness in rice bread. The higher protein rices produced relatively the more moist white rice bread. The springiness of rice bread was also significantly correlated with high amylose content and hard gel consistency. The completely chalky and large gram rices showed better suitability for fermentation and brewing. Our breeding efforts on rice quality improvement for the future should focus on enhancement of palatability of cooked rice and marketing qualify as well as the diversification in morphological and physicochemical characteristics of rice grain for various value-added rice food processings.
This study was carried out to sensory evaluation of persimmon leaf by roasting and steaming. The good sensory evaluation of persimmon leaf tea of cutting after different steamed times was shown in 3 minutes and 5 minutes steamed tea. Taste sensory score was increased in proportion to increasing of soluble solid and extraction yield and the increasing of color sensory score had relation to increasing of color value. The best sensory score was in roasted persimmon leaf tea of 5 minutes roasting in persimmon leaf tea of cutting after steaming of 3 minutes and 5 minutes. The best sensory score was shown in 3 minutes steamed in 5 minutes roasted which was culled after different steaming times. The total sensory non of roasted tea was influenced from preprocessing and total sensory score of roasted tea was higher than Just steamed tea. According to above result, the sensory score of roasted tea was more higher than steamed tea and the highest score was in 5 minutes roasted tea which was cutted after 3 minutes steamed.
The objective of this study is to investigate how patients satisfaction are affected by satisfaction with the patient menu and differentiated service resulting from QI activities and to evaluate the efficiency of QI activities. In order to improve satisfaction with menus through QI activities, this study strengthened meal round, examined the quantity of food waste produced by patients, diversified one-dish menus and used seasonal food as much as possible to reflect patients ′tastes to the maximum. With regard to cooking, additionally, it strengthened sampling and standardized recipes to maintain the constancy of taste and cooking/seasoning. From July 2003, dining time was changed from 08 : 00 to 07 : 30 for breakfast and from 17 : 30 to 18 : 00 for dinner. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows: The goal of QI was to improve food service by raising the score of "Satisfaction with Offered Menus" from 3.49 before QI to 3.55 after QI and differentiating nutrition service at the VIP ward. The score of "Satisfaction with offered menus" after QI was 3.56, and services related to the VIP ward were 7 dishes per meal, meal round once per day and the use of a napkin for a spoon in setting the table. In addition a variety of dishes were used in order to heighten the visual effect. Among the 10 items included on the patient satisfaction questionnaire, 8 items showed higher scores before QI. "Taste of meals" (p < 0.05), "Satisfaction with offered menus" (p < 0.05), "Kindness of meal serving assistants" (p < 0.05) and "Cleanliness of clothes & features" (p <0.05) of VIP ward were significantly higher than those of a general ward.
This study was carried out to investigate the characteristics of the quality of bread containing Red Ginseng Jung Kwa by-product, added in ratios of 0, 10, 20 and 30% of flour. It was found in dough and bread containing red ginseng Jung Kwa by-product that dough and loaf volume, specific loaf volume, baking loss, and pH decreased with an increasing amount of red ginseng Jung Kwa by-product. In addition, loaf weight and hardness were also reduced. In particular, hardness appeared to be 2.18 times higher for bread containing 30% Red Ginseng Jung Kwa by-product as compared to the amounts found in the control. For color, increasing the amount of Red Ginseng Jung Kwa by-product reduced the L value, whereas the a and b values were increased. In the sensory evaluation, the highest overall preference score was observed in the bread containing 20% red ginseng Jung Kwa by-product, whereas the lowest score was found in the control (no red ginseng Jung Kwa by-product added). It was concluded that pan bread containing red ginseng Jung Kwa by-product could be prepared with good acceptability, and that its optimum concentrate was found to be 20% of flour.
