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.

Purpose: The aim of this study was to investigate the factors influencing eating attitudes in female nursing students. Methods: A cross-sectional study was conducted on 121 university students in 2016. Data was collected using self reported questionnaires asking about circadian rhythm (Morningness-Eveningness Questionnaire), daytime sleepiness (Epworth Sleepiness Scale), sleep quality (Pittsburgh Sleep Quality Index), and eating attitudes (Eating Attitudes Test-26). Stress resistance was measured with a brain quotient test. The data were analyzed with a t-test, ANOVA, Pearson's correlation analysis and linear regression using SPSS 22.0. Results: Eating attitudes were associated with daytime sleepiness, sleep quality, and stress resistance of the right hemisphere. Among these, daytime sleepiness and sleep quality had a significant effect on eating attitudes. Conclusion: The results of this study suggest that sleep should be taken into account when developing interventions for preventing eating disorders in female nursing students.

In this study, nurses above the age of 20 years and working in General Hospitals located in the Gyeongbuk province were enrolled as participant. A survey was conducted to identify the relationship between types of health-eating, level of occupational stress, and degree of quality of life. An effective sample size of 120 was determined, and it was validated as a feasible count to perform the analysis by applying the PLS-SEM. We hypothesized that the physiological and psychological occupational stress levels vary according to functional, mental, and trendy types of health-eating lives and impact the degree of quality of life. This was evaluated using structural models, employing the bootstrapping method using the Smart PLS 3.0. Our results indicate that in the relationship between health-eating types and quality of life, the higher the functional health-eating type, the higher the quality of life. The association between job stress and quality of life showed that the higher the psychological work stress, the more negative the quality of life. Examining the association between the type of healthy eating and the quality of life revealed that the higher the functional health-eating type, the higher the quality of life. As a result of verifying the moderating effect of the difference in working period (less than 3 years/more than 3 years), it was found that the shorter the working period (less than 3 years), the higher the psychological stress.

Eating quality of rice attracts more and more attention from rice-eating consumers in the recent years. Thus, improvement of eating quality of cooked rice has become one of the most important breeding goals in japonica rice. Here, the generation of transgenic japonica rice with improved eating quality and grain yield are reported. Overexpression of OsSbe1 gene encoding rice starch branching enzyme 1 was driven by 35S promoter. Eleven independent homozygous $T_3$ transgenic lines were characterized and had shown higher palatability (71.2 ~ 72.6) than wild type Gopum (70.4). Moreover, transgenic rice lines showed an increase in 1000-grain weight and number of spikelets per panicle compared with the wild type. The yield of milled rice was 562.8 ~ 596.7 kg/10a in eight $T_3$ lines, but 542.1 kg/10a in wild type. Gene expression analyses in mRNA transcription and enzyme activity levels suggest that improved eating quality is due to the up-regulation of OsSbe1 gene.

Rice Quality is considered to the five catagories ; the nutritional value: the characteristics of cooking. eating and processing: grain size, shape and appearance : milling yields: and storage characteristics. Because most rice is processed and consumed in whole-kernel form. the cooking and eating quality is of important and the physical properties of the intact kernel such as size, shape and general appearance are of particular significance in determining marketing quality. Eating Quality which can be directly evaluated by consumer's panel test is so complicate and variable, and thus the objective and simplified method of evaluation is required of using appropriate instruments. Even though many researches have been done to evaluate the eating quality in various aspects such as the texture of cooked rice kernels, amylogram analysis of rice powder, amylose content. gelatinization temperature. moisture absorption of rice kernel, and cooking characteristics, none of them is satisfied for the evaluation of eating quality. The improving eating quality should be also considered to many cultural factors. such as varieties, climatic and soil conditions, cultural method, handling after harvest. milling and storage conditions. In Korea, many researches in grain size. shape and appearance, and eating quality have been done with the varietal improvement mainly by rice breeders, but no effective method of evaluation was established. A few research have been done in the relationship between rice quality and cultural factors. In the future, research in rice quality should emphasize to establish the standard evaluation method in the physicochemical properties of rice kernels for application of varietal selection. and to develop cultural practices for the preserving quality characteristics of the varieties.

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.

Eating quality is a reflection of consumer satisfaction, while beef quality grade describes carcass characteristics of chiller assessment which are largely influenced by production systems including breeding and feeding schemes. On the other hand, it should be emphasized that high palatability of beef is a function of production and processing components including breed, nutrition, animal handling, post-slaughter intervention and cookery. Numerous efforts have been made by Korean beef industry and research institutes to deliver high quality beef with which domestic beef consumers are satisfied. However, majority of studies have tended to focus on improvement of intramuscular fat content with little attention on its effect on consumer-based eating quality. Furthermore, there is very limited accessible information(if any) on relative importance of eating characteristics (eg, tenderness, juiciness and flavor intensity) to consumer satisfactory rate and palatability grade. On this regard, our recent results indicated, for example, that when m. longissimus was prepared by a thin-slice style BBQ, relative weightings of tenderness, juiciness and flavor intensity for consumer satisfactory rate were 0.4, 0.35 and 0.25, respectively. When eating quality was graded into 4 groups by a sum of tenderness, juiciness and flavor intensity after multiplying these coefficients, consumers responded that the palatability score for high quality beef should be higher than 79 points. Based on our recent experiments, the current report is intended to highlight relative importance of eating quality characteristics on consumer satisfactory rate, and threshold of eating quality grade. In addition, post-slaughter intervention techniques such as electrical stimulation and tenderstretch are given as examples of critical control points of palatability assurance program of Hanwoo beef.

BACKGROUND/OBJECTIVES: This study aims to determine contribution of meal frequency, self-efficacy for healthy eating, and availability of healthy foods towards diet quality of adolescents in Kuala Lumpur, Malaysia. SUBJECTS/METHODS: This study was conducted among 373 adolescents aged from 13 to 16 years old. Diet quality of the respondents was assessed using the Healthy Eating Index for Malaysians. Meal frequency, self-efficacy for healthy eating, and availability of healthy foods were assessed through the Eating Behaviours Questionnaire (EBQ), self-efficacy for healthy eating scale, and availability of healthy foods scale, respectively. RESULTS: The majority of the respondents (80.7%) were at risk of poor diet quality. Males ($mean=34.2{\pm}8.2%$) had poorer diet quality than females ($mean=39.9{\pm}9.0%$) (t = -5.941, P < 0.05). Malay respondents ($mean=36.9{\pm}8.7%$) had poorer diet quality than Indian respondents ($mean=41.3{\pm}10.0%$) (F = 2.762, P < 0.05). Age (r = 0.123, P < 0.05), self-efficacy for healthy eating (r = 0.129, P < 0.05), and availability of healthy foods (r = 0.159, P < 0.05) were positively correlated with the diet quality of the respondents. However, meal frequency was not correlated with the diet quality of the respondents. Multiple linear regression analysis showed that being a male, being a Malay, low self-efficacy for healthy eating, and low availability of healthy foods contributed significantly towards poor diet quality among respondents. CONCLUSIONS: In short, sex, ethnicity, self-efficacy for healthy eating, and availability of healthy foods were associated with diet quality among adolescents. Health practitioners should take into consideration of differences in sex and ethnicity during implementation of nutrition-related intervention programs. Self-efficacy for healthy eating and availability of healthy foods should be included as important components in improving diet quality of adolescents.
