Rice (Oryza sativa L.) is one of the most important food crops in the world. The eating quality of cooked rice is the most important trait japonica rice breeding in Korea. Rice varieties that produce kernels that are firm and fluffy after cooking are generally favored in countries such as India, Pakistan, and Indonesia. Whereas varieties with kernels that maintain its shape, glossiness, savory odor, stickiness, and tenderness when cooked are preferred in Korea. This study analyzed the major physicochemical components of rice grain associated with the eating quality of 20 japonica rice varieties. Physicochemical components such as the amylose content, protein content, amylographic characteristics of polished rice, and texture of cooked rice were tested using a Tensipresser as alternative indirect methods in determining rice eating quality. Evaluation of eating quality of cooked rice using sensory test was conducted with 20 well trained members. The 20 rice varieties in different eating quality showed amylose contents of 17~20%. The amylose content of rice varieties had negative correlation with peak viscosity, however positive correlation with setback viscosity was observed. The stickiness and adhesiveness of cooked rice showed correlation with the amylose content and amylopectin chain length distribution. Rice varieties with good eating quality showed less retrogradation of cooked rice and higher hot viscosity of rice flour in amylogram.
Background According to the Sasang constitutional medicine, eating habits according to the characteristics of Sasang Constitution (SC) types affect management of chronic diseases and health conditions. The aim of this study is to identify the association between eating habits, such as breakfast, eating frequency, and energy intake, according to SC, and quality of life. Method This study is a cross-sectional study of people aged 33 to 55 years, sampled by stratification based on population distribution. The SC types were classified into Taeeumin (TE), Soeumin (SE), and Soyangin (SY) using a structured questionnaire (KS-15). Items examined regarding eating habits were whether the subjects had breakfast; the frequency of eating such as breakfast, lunch, dinner, and after-dinner snacks; and energy intake surveyed using a food frequency questionnaire. As for quality of life, SF-12, which is widely used worldwide to assess health conditions, was utilized. A regression analysis was conducted on the relations between eating habits according to SC and quality of life. Results The SC distribution of the 3,895 subjects was 47% for TE, 22% for SE, and 31% for SY. The scores indicating quality of life differed for TE and SY depending on whether they ate breakfast and eating frequency groups, and those of SE varied depending on levels of energy intake. A regression analysis having adjusted all covariates demonstrated for TE a positive relation between the eating frequency of three times per day or more (compared to 1.5 to 3 meals per day) and quality of life (B=1.365, p<0.001). For SE, there was a negative association between low energy intake (compared to adequate energy intake) and quality of life (B=-1.642, p=0.004). Meanwhile, no relation was found between eating habits and quality of life for SY. Conclusion This study identified the association between eating habits according to SC types and quality of life. For TE, it was found to be important to eat evenly dispersed adequate amounts as opposed to overeating or binging at once. For SE, adequate energy intake affected good quality of life. This study suggests that eating habits based on SC improve quality of life, and health management customized for each constitution should be performed in the future through proper eating habits.

Following breast cancer diagnosis, women often attempt to modify their lifestyles to improve their health and prevent recurrence. These behavioral changes typically involve diet and physical activity modification. The aim of this study was to determine association between healthy eating habits and physical activity with quality of life among Iranian breast cancer survivors. A total of 100 Iranian women, aged between 32 to 61 years were recruited to participate in this cross-sectional study. Eating practices were evaluated by a validated questionnaire modified from the Women's Healthy Eating and Living (WHEL) study. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). A standardized questionnaire by the European Organization of Research and Treatment of Cancer Quality of Life and its breast cancer module (EORTC QLQ-C30/+BR-23) were applied to determine quality of life. Approximately 29% of the cancer survivors were categorized as having healthy eating practices, 34% had moderate eating practices and 37% had poor eating practices based on nutrition guidelines. The study found positive changes in the decreased intake of fast foods (90%), red meat (70%) and increased intake of fruits (85%) and vegetables (78%). Generally, breast cancer survivors with healthy eating practices had better global quality of life, social, emotional, cognitive and role functions. Results showed that only 12 women (12%) met the criteria for regular vigorous exercise, 22% had regular moderate-intensity exercise while the majority (65%) had low-intensity physical activity. Breast cancer survivors with higher level of physical activity had better emotional and cognitive functions. Healthy eating practices and physical activity can improve quality of life of cancer survivors. Health care professionals should promote good dietary habits and physical activity to improve survivor's health and quality of life.

By the progress of genome sequencing, infrastructures for marker-assisted breeding (MAB) of rice came to be established. Fine mapping and gene isolation have been conducted using the breeding materials derived from natural variations and artificial mutants. Such genetic analysis by the genome-wide dense markers provided us the knowledge about the many genes controlling important traits. We identified several genes or quantitative trait loci (QTL) for heading date, blast resistance, eating quality, high-temperature stress tolerance, and so on. NILs of each gene controlling heading date contribute to elongate the rice harvest period. Determination of precise gene location of blast resistance gene pi21, allowed us to overcome linkage drag, co-introduction of undesirable eating quality. We could also breed the first practical rice cultivar in Japan with a brown planthopper resistance gene bph11 in the genetic back-ground of an elite cultivar. Discovery of major and minor QTLs for good eating quality allowed us to fine-tune of eating quality according to the rice planting area or usage of rice grain. Many rice cultivars have bred efficiently by MAB for several traits, or by marker-assisted backcross breeding through chromosome segment substitution lines (CSSLs) using genetically diverse accessions. We are also systematically supporting the crop breeding of other sectors by MAB or by providing resources such as CSSLs. It is possible to pyramid many genes for important traits by using MAB, but is still difficult to improve the yielding ability. We are performing a Genomic Selection (GS) for improvement of rice biomass and grain yield. We are also trying to apply the genome editing technology for high yield rice breeding.
We desperately recognize from the economic situation in IMF crisis that only competive goods and serviced. It is anticipated that this difficult situation will probably be continued till 1999. Therefore, it is necessary to think over real aspects of eating=outdoors in IMF period and to provide an opportunity to confront with this crisis. Analysis a recent tendency of domestic eating-outdoors business, there appears, first of all, dual types of eating-outdoors; the one is a sort of 'Cost Sale', which provides some special menu with lowest prices, and the other is a type of 'Family Restaurant', which regards the atmosphere of the place as one of the most essential elements. Both types are getting more popular today. As the result, neither of the alternative cannot recover the current Depression. It is natural that no other conditions can compete with good tastes, fancy atmosphere, and good prices. As a matter of fact, however, it is quite difficult to run this type of bussiness adjusted the above whole conditions. Therefore owners of eating-house must decide to run either ' Cost Sale' or 'Family Restaurant' first and investigate some problems and conditions accordingly. In ane way, the owner intensively visits to some eating houses which is similar style in size and management to that of his style in size and management to that of his and look over what is good and what is bad Right after this investigation, it is efficient for he or she to improve his or her business style in size and management in a short period. It is helpful to check some complements; improvement of signboards, cleaning up of the interior, selecting suitable menu, adjusted prices, tastes, and service quality etc. Although eating-outdoors business is hard hit by IMF, We hope that it would rapidly be brisk in 2000, becaused by that time the basis of each industry would be high qualified, and rich technology would be accumulated.
This study was performed to assess the effect of eating behaviors and health-related variables on overall dietary quality. Ninety-four(male 21, female 73) elderly who were over 60 residing in middle income areas in Cheongju city participated. Information on general characteristics of the elderly, health-related life style, regularity of meal, meal balance and desirable eating habits were obtained by interview based on questionnare. Dietary nutrient intake data were obtained through the 24 hour recall method. The mean age and BMI of the subjects were 73.3 years old and 23.3(male 21.8 female 23.7) respectively. The proportions of underweight and hypertension were 19.2% and 36.2%. Most nutrients except vitamin $B_2$ and calcium were consumed over 75% of the RDA. The Mean Adequacy of Ratio(MAR) of nutrient intake was 0.64(male 0.72, female 0.62). The average score of regularity of meal, meal balance, and desirable eating habits was 14.4 out of a possible 16, 13.7 out of a possible 24 and 5.5 out of a possible 16 points respectively. Male than female, older subjects than young subjects, and those living with their spouses than with other family or living alone had better scores in eating behaviors. Smoking, chewing ability and eating alone vs eating with company affected overall of regulality of meal and meal balance(p<0.05). Positive correlation (p<0.05) was also dietary quality. There was a positive correlation between the mean adequacy ratio, score observed between scores in regularity of meal and meal balance. Therefore, the elderly should be encouraged to eat a variety of food, maintain good dental health, keep regularity of meal and have meals with company to help improve overall dietary quality and eventually achieve optimal nutritional status.
This study was performed to approach Korean food proverbs from the stance of food ethics. Both modern principles and traditional principles of food ethics were applied to select proverbs. The modern principles include a respect for life, justice, environmental preservation, and the priority of safety. The traditional principles were longevity and good health, poverty (escaping) and wealth (pursuing), eating luck and fortune, priority of food, virtue, and taste and quality (economics). All the principles except environmental preservation and the priority of safety have adequate food proverbs, since environmental disruption and food safety were not serious issues in the past.
To find out the reference data of the school food service system, I serveyed four primary schools in Seoul, Korea and Nara, Japan respectively. The school children and their parents of whom arbitrary selected two classes among each primary school, were taken the questionaire about the present school food service system and their favorate food. The results were as follows; 1) 74.8% of Korean and Japanese children, and 92.5% of their parents were in favor of school food service. 2) Korean childrin wanted more amount of food and less salty taste. 3) Korean and Japanese children and their parents believed that the school food service system correct children's unbalanced diet. 4) Korean children wished more kinds of foods, western-styled cooking and that the food would be served in warm state. 5) Korean parents wanted that school food service system should be natural and better quality food material, and teacher should educate good eating habit. 6) Korean school children prefer yogurt, cuttle-fish, chicken, bean-curd, tomato, orange, dried laver, sweet potato, pine-mushroom in each food group. In conclusion, school food service system should be enough to meet children's good nutrition status, and the menu would be selected with consideration of children's preference and Korean traditional diet habit. Good table manner and eating all kinds of foods should be targht by school food service system as well as preparing good quality of food.
The purpose of this study was to observe the effect of eating a raw egg by professional or nonprofessional voice users on their voice quality and the duration of the effect. 20 professional voice users and 20 nonprofessional voice users participated in the experiment and they had gone through stroboscopy to have no vocal or laryngeal diseases. The voice exam was performed three times: before eating a raw egg (1st period), right after eating it (2nd period), and 10 minutes later (3rd period). By using Multi-dimensional Voice Program which is a software of Computerized Speech Lab 4500 as a voice analysis instrument, the authors checked the F0, Jitter, Shimmer, Noise to harmonic ratio (NHR), and Voice Range Profile (VRP). Results showed as follows: Firstly, vocal hygiene was good in 57.5% of the total subjects and was poor in 42.5%. 40% of professional voice users and 75% of nonprofessional voice users hand good quality. 77.5% of the total subjects had the vocal fatigue while 22.5% of the subjects did not. 95% of the professional voice users and 60% of nonprofessional voice users complained the vocal fatigue. 60% of the total subjects reported a subjective vocal symptom. 65.0% professional voice users and 70.0% of nonprofessional voice users reported a voice symptom. From the results above, we suggest that eating a raw egg may lead to imporve voice quality of the professional voice users.
The dietary habits and eating behaviors of nonagenarian subjects over 90 years old in Korean representative longevity belts of Damyang, Gokseong, Kurye, Sunchang were evaluated. The subjects of the study were 91 elderly people (26 males and 65 females) over 90 years old and their dietary habits, food preferences and meal patterns were collected by individual interview. The percentage of subjects, who answered 'very good' or 'good' for their health status, was $65.9\%$. In this study, $55\%$ of subjects were without chronic diseases, and there was no significance difference in gender. Many subjects had performed regular exercise and outdoor activity. The rate of eating together with their family was $79.1\%$. Most of subjects ($91.2\%$) had a regular mealtime consuming three meals a day, and they had good appetite and pleasure of eating. The higher preference of food group was fruits ($95.6\%$), legumes ($94.5\%$), mushrooms ($93.4\%$) and vegetables ($92.3\%$), but the amount of intakes is higher in vegetables than the others. Eating with family, regular exercise and self-rated good health are improved their nutrient intakes. Most frequently consumed meal pattern was rice plus soup and side dishes. The side dish consumed frequently was Namul (blanch and seasoned vegetables). From this study, the nonagenarian populations in longevity belt in Korea have good dietary habits such as regular mealtime, constant amount of meal and eat with pleasure. They are taking Korean traditional meal pattern, providing enriched antioxidant vegetable foods. Also, it can be concluded that the amount and quality of diet in the long-lived elderly are responsible for the Korean traditional family system.
