The study carried out a 15-day feeding trial of the fleshy shrimp broodstock that have just finished their first spawn using five different maturation feed types (three types of manufactured feed, fresh feed, and commercial feed) to induce multiple spawning in the shrimp and then analyzed and compared hemolymph levels of total protein, total lipid, hemocyanin, glucose, and cholesterol as well as ovary histology between the treatments to identify the potential of the experimental diets to be utilized as maturation feed. The study found that the manufactured diets of polychaetes + clam and polychaetes + clam + squid resulted in significantly higher levels of lipid and protein in shrimp hemolymph suggesting an indicator of multiple spawning in the fleshy shrimp. The other manufactured diet of polychaets + squid led to the highest 2nd spawning with significantly lower levels of lipid, protein, and cholesterol in shrimp hemolymph. The fresh feed treatment showed similar hematological as well as histological responses to the manufactured diet of polychaetes + squid, but with a significantly lower spawning volume compared to the other treatments. The study demonstrated that the manufactured diets could replace fresh feed as maturation feed and attain a higher shrimp maturation than the commercial feed.

Objectives: The objective of the present study was to investigate the lipid and the antioxidant regulatory potential of a multigrain diet in laboratory animals with reference to lipid profiles, tissue lipid peroxidation and antioxidant status. Methods: Two types of diets, with or without addition of cholesterol, were used in the study - a commercial diet and a formulated multigrain diet (with Sorghum vulgare, Avena sativa, Pennisetum typhoideum, Oryza sativa, Eleusine coracana and Zea mays grains). After a 10-week period of feeding the diets to albino rats the plasma, liver and fecal lipid profiles and the hepatic and renal antioxidant status of the animals that were fed the commercial and the formulated diets (with and without cholesterol addition) were assessed. Results: The commercial diet supplemented with cholesterol elevated the levels of plasma total lipids, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and very low-density lipoprotein cholesterol (VLDL-C), as well as the atherogenic index (AI). The high-density lipoprotein cholesterol (HDL-C) content and the antioxidant profiles (total ascorbic acid, superoxide dismutase, catalase, glutathione peroxidase reduced glutathione) declined along with increases in lipid peroxidation. The formulated diet (with and without addition of cholesterol) was found to be more efficient than the commercial diet in controlling plasma, hepatic and fecal lipid profiles, as well as hepatic and renal lipid peroxidation and antioxidant status, than of the hypercholesteremic animals. Conclusion: The multigrain diet used in the present study is effective in countering the hyperlipidemia and oxidative stress caused by high cholesterol intake.

In this study, 230 female college students in Seoul area were surveyed to evaluate their eating habits and behavior, physical activities, and patterns of purchasing diet/low-calorie food. Their body composition was also determined using bioelectrical impedance(Inbody 520). The subjects were divided into two groups according to their BMI index with a mean BMI of 20.2$\pm$1.5(normal) weight and 25.0$\pm$1.7(obesity). Overall, 85.7% of the subjects reported that the food they purchase depends more on their preferences than the nutritional value of the food. When the two groups were compared there was no significant difference in the frequency or experience of purchasing diet-foods. Indeed, 69.3% of all female college students had purchased diet foods, and most consumed these foods 2~3 times a week. Obese group preferred a savory taste, while normal group preferred a sweet taste. The majority of the subjects(80.8%) answered that they "read nutritional labels carefully upon purchasing diet food", and that they examined calories(61.8%) and total fat(48.5%) most carefully. Of the types of low-calorie/diet foods purchased, beverages were the most commonly obtained; followed by noodles, diet-bars, and snacks. The most commonly purchased low calorie snacks were "potato-type C(hot-flavor)" and "potato-type A(salty-flavor)", while the most commonly purchased diet-bars were "low calorie-type A"(55.3%) and "high protein-bar"(32.3%). The most commonly purchased noodles were "thick noodle type"(65.1%), while the most commonly purchased drinks were "cereal tea"(65.1%) and "mixed herb tea"(66.0%). Overall, factors such as self-esteem or the degree of body satisfaction, rather than obesity(BMI index) itself, were significantly correlated with the frequency of purchasing diet-foods.

This study was designed to observe the effects of both control and atherogenic diets on the cholesterol and triglyceride (TG) in serum and liver of adult rats fed diets supplying two levels of dietary fat and two different sources of dietary protein in early life. For the first experimental period, the rats were assigned into the four diet groups: High fat, casein (HC); High fat, gluten (HG); Low fat, casein (LC): Low fat, gluten (LG). Each group was subdivided into control and atherogenic groups for the second experimental period. Cholesterol and TG were determined in serum and liver after 7 hr fasting. The body weight gain was greater in the rats of the casein groups than those of the gluten groups tut not influenced by the level of the dietary fat. The difference in body weight from the quality of dietary protein in the first period was not disappeared even after the second period. After the first period, higher serum cholesterol was observed in the rats fed either casein or high fat diets. With the second experimental diet, rats fed atherogenic diet showed higher serum cholesterol concentration but lower serum TG levels compared to those fed control diet, regardless the diets fed in the first period. Serum cholesterol level of the rats of both groups which had been fed high fat diets in early life was increased compared to those of the low fat diet groups. This effect was more pronounced with the atherogenic diet groups than control groups. However, no differences were found in serum cholesterol levels resulted from the different types of dietary protein fed in the first period. Serum TG concentration was not influenced by the quality of protein and level of fat in the diet but seemed to be mere affected by the amount of carbohyrates in the diet. Liver cholesterol per unit weight was greater in the gluten diet groups than in the casein groups but total cholesterol was higher in casein fed rats. There were no differences in liver TG among the groups.

Korean medicated diet (KMD) is not a simple combination of food and Chinese drugs, but a special carefully constructed diet made from Sasang constitutional medicines, food and condiments under the theoretical guidance of diet preparation based on differentiation of symptoms and signs of traditional Sasang medicine (TSM). It combines the functional efficacy of medicine with the delicacy of food, and can be used to prevent and cure diseases, build up one's health and prolong one's life. Korean traditional medicated diet has a long history of development. Although influenced by Chinese medicine, Korean traditional medicine has been developed into a unique system of traditional medicine that has surpassed the continental medical practice, sublimating itself into a native medical practice suitable to Korean lifestyles and physical constitutions. In the 19th century, Lee Jema's Sasang medicine (medicine of four types of energy determining the physical constitution) was introduced. It is an integration of mind and body according to the individual's physical constitution that is categorized allowing a customized method of treatment ideal for each category-making the content of Korean traditional medicated diet even richer. The characteristics of Korean medicated diet are as follows: (1) Laying stress on the wole, selecting medicated diet on the basis of differential diagnosis. (2) Suitable for prevention and treatment, outstanding in effect. (3) Good in taste, convenient for taking. KMD refers to drink and food according to certain prescriptions, by processing and cooking that can be used either for prevention and cure of diseases, or for health care and recovery. The purpose of this review is to introduce TSM and KMD based on Sasang constitutional medicines.

BACKGROUND/OBJECTIVES: While plate waste has been widely investigated in hospitals, there have been minimal studies specific to the texture-modified diet (TMD). This study aims to determine the percentage of plate waste among patients prescribed with TMD and its contributory factors. SUBJECTS/METHODS: This was a single-centre study conducted in the university hospital on three types of TMD (blended diet, mixed porridge, minced diet) during lunch and dinner meals. Weighing method and visual estimation method assisted by digital photograph were adopted in this study. Face to face interview was carried out to investigate on 1) the food/food service quality factors in terms of patients' satisfaction level towards sensorial quality of food and food services provided and 2) the clinical/external factors including appetite, the provision of oral nutrition support, time taking the diet, the need for feeding assistance and the length of hospital stay. RESULTS: The mean percentage of overall plate waste of 95 patients receiving TMD was high (47.5%). Blended diet was identified as the most wasted diet (65%) followed by minced diet (56%) and mixed porridge (35%). Satisfaction level among patients was moderate. Patients on TMD in general had higher satisfaction level on the aspect of food service as compared to food quality. Substantial association between sensorial qualities of food and plate waste were varied according to individual TMD type. A multiple linear regression showed that only the satisfaction level toward the aspects of appearance and variety of foods were the predictors of TMD plate waste (R² = 0.254, P < 0.05). CONCLUSIONS: A significant relationship between the percentage of plate waste and the overall satisfaction level of patients receiving TMD suggests that vigorous strategies are needed to reduce the food waste of TMD which will lead to a better nutritional status and clinical outcomes among the patients.

Objectives: This study was carried out to determine nutritional status of elderly patients in a long-term care hospital according to meal type and eating ability. Methods: Subjects were 47 female patients aged over 65 ($79.3{\pm}7.1$ years) who resided in a long-term care hospital in Seoul. Thirty seven patients who ate diet orally were grouped according to meal type (27 general diet and 10 soft diet) and eating ability (26 eating by oneself and 11 eaten with help) and 10 were on tube feeding. Nutritional status was determined by food consumption and mid-arm circumference. Results: The mean adequacy ratios (MARs) of 12 nutrients (protein, calcium, phosphorus, zinc, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, folic acid, vitamin C) were 0.687 for general diet, 0.565 for soft diet, 0.680 for eating by oneself and 0.677 for eaten with help, which were significantly lower than 0.982 for tube feeding (p < 0.05 or p < 0.01). The patients on tube feeding had significantly lower % arm circumference compared to those who ate general diet (84.0% vs. 95.4%, respectively, p < 0.05). Nutrients intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) were not different between meal types as well as eating ability. The most insufficiently consumed nutrients by the patients on diet were folic acid, vitamin $B_2$, and calcium (NAR 0.334~0.453, 0.515~ 0.539, and 0.516~0.533, respectively). Conclusions: The results suggested that regardless of meal type or eating ability, the subjects who were on diets in this study might have inadequate intake of folic acid as well as vitamin $B_2$, and calcium, which need to be reflected on menu planning. The measurement of mid-arm circumference presented more risk of malnutrition of patients on tube feeding than those on diets, despite apparently better nutrient consumption.

かつてフェミニズムや男女平等を批判していた安倍晋三首相率いる第二次安倍政権は,2012年以降,女性の社会進出を後押しする政策を積極的に促進し,2015年には女性の職業生活における活躍の推進に関する法律（女性活躍推進法)を成立させている。女性活躍推進法は,女性政策ではなく,女性を利用しようとする経済政策であるとの批判が多いが,一方では女性のための政策としての側面もあるとの指摘もあり,保守政権による女性政策の興味深いケースとなっている。本稿は,女性活躍推進法の審議過程における女性の実質的代表の内実を明らかにすることを目的とする。具体的には,安倍政権による女性政策,また,女性の実質的代表に関する先行研究の知見から導き出した二つのリサーチクエスチョンへの答えを,法案審議での議員発言をデータとして提示することが本稿の課題である。第一に,女性活躍推進法が女性活用の経済政策であるという評価から,審議過程においても,女性の利益や権利を代表する発言よりも,女性を経済成長や少子高齢化社会における資源として活用しようとする発言が多いのかどうかを探る。第二に,女性を実質的に代表する発言があるとすれば,どのような発言内容が見られるのかを明らかにする。特に,保守政党である自由民主党が多数を占めている国会での審議においては,女性の家庭内ケア提供役割を所与とした女性のための発言が大勢を占めているのかに注目する。これらのリサーチクエスチョンに答えることで,女性活躍推進法を巡る女性の実質的代表の有り様,また保守主義と女性の実質的代表の関係を明らかし,女性の実質的代表の研究に貢献することを目指す。分析の結果,女性を活用しようとする発言は,女性を代表する発言,また女性活用の姿勢を批判する発言と比べて数が少なかったこと,議員発言によって多種多様な女性が代表されていることが明らかになった。また,保守系議員による,女性の家庭内ケア提供役割を所与とした保守的な女性の代表発言がある一方で,主に野党議員による,保守的ではない女性の代表発言も多くあったことも示された。これらの分析結果は,保守政権が支配する議会であっても,非保守的な女性の実質的代表が,少なくとも審議過程においては可能であることを示唆している。
