Taurine has been reported to prevent cardiovascular disease and improve liver function, diabetes, and platelet function. However, there are few studies on the effects of taurine in Koreans. The purpose of this study was to investigate the effect of basal doses of taurine on blood glucose, liver disease, and lipid diseases among Korean college students. The study included a taurine intake group and a control group; each group consisted of 15 students. Taurine was administered at a standard dose of 1,000 mg for 2 weeks postprandial. All subjects were excluded from medication or other food besides meals provided by the dormitory. The liver test gamma-glutamyl transferase (GGT) in the taurine group decreased to $23.53{\pm}25.73IU/L$ before intake and to $15.15{\pm}4.91IU/L$ after intake (P=0.186). Lipid metabolite triglyceride (TG) was $100.42{\pm}28.33mg/dL$ before intake and $80.22{\pm}17.08mg/dL$ after intake (P<0.05). Total cholesterol (T-Cho), low density cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C). Consequently, taurine improved liver function and lipid metabolism. Hematologic tests showed a decrease in segmented neutrophil percentage and an increase in lymphocyte percentage. Thus, taurine also seems to be related to immunological function.

Food intake data from 228 persons (96 male adult ranging in age from 19 to 54, 27 female adult ranging in age from 20 to 46, 54 boys ranging in age from 9 to 11, and 51 girls ranging in age from 8 to II) were studied with respect to the shape of the underlying probablity distributions. For each menu items distributional shapes of food intake were different. Most of distributions for food intakes from normaJ distributions. From food intake data of 2 meals nutrition intake data are calculated. For each meal, energy, protein, fat, carbohydrate, fiber, calcium, iron, vitamin A, thiamin, ribofavin, niacin and vitamin C were computed and thier distributions were compared with normal distributions. Distributions for adult female showed normal distributions for some food items. For nutrient intake data from male adults, distributions for vitamin C from 1st meal and calcium from 2nd meal were marginal and the remains were differed from normal distributions. For adult female and childern, distiributions for some nutients were differed from normal distributions. It is hard to find special patterns for each nutrient distributions. Therefore the normal distributions assumptions should be verified prior to applying parametric techniques to thier data. If those assumptions are not valid, non-parametric techniques should be used to analyze their data.

This research aims to gain a better understanding of college students' thoughts on what factors make them happy and contribute to enhancing their happiness. We focused on the relationship between their self-assessed happiness and various factors affecting happiness, such as their socio-economic status, relationships with others, future orientation, and daily activities. Survey data were collected from October, 2014 to December, 2014 at a South Korean University. The final total number of respondents was 474 from 500 distributed questionnaires, after excluding 26 responses with missing values and unanswered items. The response was comprised of 247 male students, and 227 female students, and of 268 freshmen, 145 sophomores, 35 juniors, and 26 senior students. Factors that were statistically significant were gender, year, average cost of leisure, appearance satisfaction, conversation hour with parents, having girlfriend/boyfriend, sexual experience, number of friends, satisfaction with major, Grade Point Average (GPA), studying hours, time for self-improvement, reading hours, use of smart phone hours, number of daily meals, exercise hour, schedule management and future goal setting. This research was conducted utilizing only data from one university and so it may not be appropriate to generalize the results. Moreover, some of the variables are not in line with previous studies on happiness. Some other mediating variables may exist. Therefore, following research should be conducted.

Two experiments were conducted to compare the feed intake patterns and growth performance of Meishan and Yorkshire growing pigs. Experiment 1 was carried out over a 6-wk period and used 48 barrows with equal numbers of purebred Meishan (M) and Yorkshire (Y). Pigs were allocated to four groups of 12 pigs consisting of equal numbers of M and Y. Initial BW were $36.4{\pm}0.32kg$ and $42.1{\pm}1.41kg$ for M and Y, respectively. Experiment 2 was carried out over a 5-week period and used 48 pigs consisting of equal numbers of both barrows and gilts and of crossbred Meishan$\times$Yorkshire (MY) and purebred Yorkshire (Y) animals. Pigs were allotted to 6 pens of 8 pigs, with 4 single- and 2 mixed-genotype groups (initial $BW=28.5{\pm}0.99kg$). In both experiments, pigs were given ad libitum access to a grower diet (17% crude protein, 0.9% lysine, 3365 kcal/kg ME) via feed intake recording equipment (F.I.R.E.). Pigs carried an ear-tag transponder with an unique identification which allowed the time, duration, and size of individual meals to be recorded. In Exp. 1, Y had higher ADG (721 vs 353 g, p<0.01), daily feed intake (DFI; 2.338 vs 1.363 kg, p<0.01), made more frequent visits to the feeder per day (NFV; 18.5 vs 7.7, p<0.01), had a shorter feeder occupation time per visit (FOV; 7.4 vs 12.9 min, p<0.01), and ate less feed per visit (FIV; 130 vs 177 g, p<0.01) than M pigs. Feed consumption rates (CR) were greater for Y compared to M (19.3 vs 14.8 g/min, p<0.01). Feeder occupation time per day (FOD) was longer for Y than M (114.3 vs 82.8 min/pig, p<0.01). Yorkshire pigs visited the feeder more frequently between 0800 and 1100 h. Meishan pigs showed more frequent feeder visits between 0600 and 0800 h, and between 1600 and 2100 h when feeding competition with Y was reduced. In Exp. 2, there was no effect of genotype or group composition on DFI, ADG or gain:feed ratio. Crossbred pigs (MY) made fewer feeder visits (12.6 vs 17.7, p<0.01), and had greater FIV (124 vs 98 g/visit, p<0.01), and longer FOV (8.11 vs 7.24 min/visit, p<0.01) and FOD (112 vs 100 min, p<0.05) than Y pigs. Results of this study suggest substantial genetic variation in feeding patterns as well as in growth performance.

This experiment was carried out to compare the effects of six different plant protein sources such as soybean meal, extruded full-fat soybean, canola meal, rapeseed meal, cottonseed meal and perilla meal as a sole protein source of diets on growth performance and amino acid bioavailabilities in growing-finishing pigs. A total of 54 pigs with average 25 kg of body weight were used as experimental subjects for a 65-d feeding trial. Digestion trial was carried out with seven ileal-cannulated pigs. The most rapid rate of weight gain was observed in pigs fed soybean meal and full-fat soybean, the moderate one in pigs fed canola meal and cottonseed meal and the least one in pigs fed rapeseed meal and perilla meal (p<0.005). Feed efficiency was better for groups fed soybean meal and full-fat soybean than other protein meals (p<0.05). The apparent ileal digestibilities of essential amino acids of soybean meal and full-fat soybean (82.5% and 81.6%) were significantly (p<0.05) higher than those of other protein sources (61.2 to 69.4%). Regardless of protein sources, the apparent ileal digestibility of arginine was highest, whereas that of histidine was lowest among essential amino acids. Proline had the lowest digestibility among non-essential amino acids. True amino acid digestibilities tended to be higher than apparent amino acid digestibilities. The differences between true and apparent ileal digestibilities were greater in canola meal, rapeseed meal or cottonseed meal than other protein sources. The differences was greatest in praline except for cottonseed meal. The fecal digestibility appeared to be higher than the ileal digestibility. The differences between fecal and ileal digestibilities were greater in canola meal, rapeseed meal, cottonseed meal and perilla meal than in soybean meal and full-fat soybean. In general, praline was the most disappeared amino acid in the hind gut, while the net synthesis of lysine in the large intestine was observed in all protein sources except perilla meal. It is appropriate that swine feeds should be formulated based on true ileal amino acid digestibility of protein sources for pig's normal growth.

This study researched the toothbrushing behavior and perception of oral health condition in accordance with the use of cafeteria, 280 Students of 28 high schools in Daegu and Gyeongbuk to identify the relationship between cafeteria use and oral health. and then obtained statistically significant results like below. Toothbrushing after meals and snacks was high with female students and Grade3. Rinsing mouth for ten times or more after toothbrushing was high with female students and private car while the use of oral care products was high with female students, Grade3, and private car. The whole average frequency of using cafeteria was 2.26 while the perception of oral health condition was 3.44. The frequency of using cafeteria was high with Grade2, before time for school, and lots of allowance. The perception of oral health condition was high with male students, school bus, and lots of allowance. The frequency of using cafeteria in accordance with toothbrushing behavior was high with toothbrushing for longer than three minutes(2.45) while the perception of oral health condition was high in case when using oral care products(3.32). In the results of multiple regression analysis to understand the influence of perception of oral health condition, general characteristics, and toothbrushing behavior on the frequency of using cafeteria, it was analyzed like Y(frequency of using cafeteria)=-952+.393(perception of oral health condition)- 1.721(time for school)+ .991(allowance)+ 1.124(duration of toothbrushing). Based on the results above, it would be necessary to establish the educational system to continuously practice the correct oral health care education in school.

Background: Although soybean meal (SBM) is excellent source of protein in diets for poultry, it is sometimes inaccessible, costly and fluctuates in supply. The SBM can partially be replaced by full-fat SBM, but the meals prepared from raw full-fat soybean contain antinutritional factors. To avoid the risk of antinutritional factors, heat treatment is always advisable, but either excessive or under heating the soybean could negatively affect the quality. However, the potential for further improvement of SBM by supplementing with microbial enzymes has been suggested by many researchers. The objective of this study was to evaluate the performance and ileal nutrient digestibility of birds fed on diets containing raw soybeans and supplemented with microbial protease. Methods: A $3{\times}2$ factorial, involving 3 levels of raw full-fat soybean (RFFS; 0, 45 or 75 g/kg of diet) and 2 levels of protease (0 or 15,000 PROT/kg) was used. The birds were raised in a climate-controlled room. A nitrogen-free diet was also offered to a reference group from day 19 to 24 to determine protein and amino acid flow at the terminal ileum and calculate the standardized ileal digestibility of nutrients. On days 10, 24 and 35, body weight and feed leftover were recorded to calculate the body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR). On day 24, samples of ileal digesta were collected at least from two birds per replicate. Results: When RFFS was increased from 0 to 75 g/kg of diet, the content of trypsin inhibitors was increased from 1747 to 10,193 trypsin inhibitors unit (TIU)/g of diets, and feed consumption of birds was also reduced (P < 0.05). Increasing RFFS level reduced the BWG from hatch 0 to 10 d (P < 0.01) and hatch to 24 d (P < 0.05). The BWG of birds from hatch to 35 was not significantly (P = 0.07) affected. Feed intake was also reduced (P < 0.05) during 0 to 35 d. However, protease supplementation improved (P < 0.05) the BWG and FCR during 0 to 24 d. Rising levels of RFFS increased the weight of pancreas (P < 0.001) and small intestine (P < 0.001) at day 24. Except for methionine, apparent and the corresponding standardized ileal digestibility of CP and AA were reduced (P < 0.01) by increasing levels of RFFS in diets. Conclusion: This study showed that some commercial SBM could be replaced by RFFS in broiler diets, without markedly compromising productivity. The AID and SID of CP and lysine were slightly improved by dietary supplementation of microbial protease.

Purpose: This study examined whether there was a difference in the nutrients and food intake of young children depending on their lunch places. Methods: The dietary survey data of the fifth Korea National Health and Nutrition Examination Survey (2010 ~ 2012) were used. The children were grouped into either a child care center lunch group (n = 728) or home lunch group (n = 592) and their nutrients and food intakes were compared. Results: No differences in the 24-hr energy intake and energy intakes from lunch and dinner according to the lunch places were observed. The percentage of breakfast energy was lower in the child care center lunch group, whereas the percentage of snack energy was higher. In children aged 3 ~ 5 years, the sodium, potassium, and vitamin C intakes were high in the child care center lunch group. The 1 ~ 2 years and 3 ~ 5 year old children's vegetable intake from lunch was significantly higher in the child care center lunch group than in the home lunch group. Children aged 3 ~ 5 years in the child care center lunch group consumed more beans and fish at lunch. The adequacy of nutrients and food diversity of child care center lunch appear better than home lunch. Conclusion: Parents and care providers need to make efforts to use diverse foods, such as vegetables and fish, in children's meals to provide balanced diets and promote healthy eating behaviors to their children.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

A theory of the school which attach great importance to moxibustion therapy was more developed from 'Ge Hong(葛洪)', 'Wang Tao(王燾)' up to "BianQueXinShu(扁鵲心書)" of 'Dou Cai(竇材)' in Song Dynasty. The first volume of "BianQueXinShu" was described about the principles of health preserving method, diagnosis, treatment related with meridian system, support Yang theory, moxibustion therapy over the 10 chapters and in the continued 3 chapters, explained the symptoms and related moxibustion therapies. The summary is as follows. The Yang energy is the essence of the human body and it is minutely explained in "Hwangdineijing(黃帝內經)". However, the younger scholars after 'Zhang Zhongjing(張仲景)' held different views with "Hwangdineijing" so they didn't control serious diseases. Supporting the Yang energy, it will be possible to human body in good health and long life and perennial youth and longevity. To do like this, the first important thing is a moxibustion, the second is a Taoist hermit medication(丹藥) and the third is well usage of Radix Aconiti Lateralis Preparata. According to the sequence of Yang energy deficiency, the stages of diseases are classified as Ordinary Gi(平氣), Latter deficient state(微虛), The more deficient state(甚虛), Exhausting state(將脫), Exhausted state(已脫) and in the consideration of each stage, it is used gradually with warm-natured berbs, warm-acrid herbs, warm-heated herbs and moxibustion therapy. If it comes to the stage of Exhausted state, the Yang energy is too weak to treat a disease. Therefore it is easy to harm human body with usage the treatment of the Purgationist school theory or the Cold and cool medical school theory, so it is needed a great attention to use these therapies. To summarized the keynote of 'Du Jae''s moxibustion therapy, the one is a minority of selection of points(1$^{\sim}$2 acupuncture points), the second is a majority of moxibustion units(50$^{\sim}$500 units), and the other is a focused selection of points on spleen and kidney(especially Gwanwon, CC4). And in this book, it was explained concretely about the size of moxibustion, according to the experiment with mentioned size, the burning time of moxibustion was almost 4 min 40 sec, so the big size moxibustion was one of the characteristic of moxibustion therapy revealed in this book. Also it was used 'Suseongsan(睡聖散)' - a kind of analgesic herb complexes - to reduce a pain during the usage of moxibustion therapy in this book. To develop the moxibustion theory, it is more investigated in the future that there wasn't significant relation between Gwanwon(CC4) and spleen and kidney meridian in theory, compared to many used Gwanwon(CC4) in the prescription, where as mentioned the importance of spleen and kidney in treatment, that considering the burning time(1 unit - 4 min 40 sec, 12 units an hour, maximum 288 units a day) there were no guidances about meals, sleeping, stool and urine, and that there was no concrete study about the toxicity of 'Suseongsan' as analgesic moxibustion therapy.
