The amount of salt intake of Korean people is 11.4 grams per a day, which is 2.3 times of the recommended daily salt intake by WHO - 5 grams of salt a day. The relationship between high salt consumption and increased risk of high blood pressure, observed not only in hypertensive but also in normotensive patients. High salt intake is also associated with an increased risk of heart attack, cerebral ischemia and osteoporosis. Therefore, this research is for developing a salt taste sensor to reduce sodium consumption and improve meal habits for the perception of a more bland taste of most foods. When the sensor was put into food sample, current intensity achieved with distribution cables. Current intensity was correlate with a simple equivalent of salt taste stimulus intensity. The salt taste sensor consists of salinity & temperature measuring probe, signal processing circuit and LCD display & LED warning light. When salinity is going over a set point, LCD displayer indicate salt taste on LCD panel by percent value (%), and at the same time, blue LED light change to red LED light. So we could know the grade of salt taste in soup before meals conveniently and objectively. The results show that operating range of 10 to $80^{\circ}C$ and accuracy of ${\pm}0.1%$ were achieved with an analysis time of about 2 or 3 sec. Moderate reductions in salt intake can help to avert adult diseases and lead a healthy life.

This study was carried out to estimate the relationship between dietary intake, blood level, and urinary excretion of minerals and blood pressure in 30 healthy adults living in rural area of Korea(12 males and 18 females). Analysis for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling before measuring blood pressure. The mean blood pressure of subjects was 117.50/80.83mmHg in males and 110.00/73.89mmHg in females. The mean daily intakes of Na, K, Ca, P, Mg, Fe, Cu, Zn estimated for 3 days were 199.97mEq, 49.56mEq, 452.50mg, 725.57mg, 240.40mg, 12.48mg, 3.41mg, 8.28mg, respectively. The serum concentration of Na, K, Ca, P, Mg, Fe, Cu, Zn were 139.83mEq/dl, 4.06mEq/dl, 8.86mg/dl, 3.28mg/dl, 2.13mg/dl, 0.12mg/dl, 0.12mg/dl, 0.14mg/dl, respectively. The 24-hour urinary excretions of Na, K, Ca, p, Mg, Fe, Cu, Zn estimated for 169.60mEq, 39.37mEq, 80.40mg, 398.97mg, 64.77mg, 0.21mg, 0.07mg, 0.29mg, respectively. No significant correlation was found between dietary intake, serum concentration, and urinary excretion of minerals and blood pressure. But, the serum Ca/Mg ratio showed negative correlation with the systolic and diastolic blood pressure at the level of significance of 5%. The study verifies the need for more systematic studies on interrelationship among minerals and mineral requirements in normotensive and hypertensive subjects.

BACKGROUND/OBJECTIVES: Due to recent changes in social structure, single-person households are on the rise worldwide and therefore the interest in the quality of life of singles is increasing, but the research on the relationships related to their diet-related quality of life is scarce. This research analyzes the structural relations in the effect of convenience food satisfaction and quality of life according to dietary style of Korean, Japanese and Chinese singles. SUBJECTS/METHODS: The targets of this study were Korean, Japanese, and Chinese singles, identified as adults between the ages of 25 and 54, having economic capabilities or working and living alone, either legally or in actuality having no partner. A statistical analysis was conducted using SPSS12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. In an attempt to study the level of satisfaction with convenience food in accordance to dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. RESULTS: Of the three countries, regarding the effect of dietary style on singles' quality of life, the convenience-oriented style was found to have a negative effect on Korean singles' overall quality of life, but a positive effect on Japanese singles' overall quality of life, and a negative effect on Chinese singles' positive psychological aspect of quality of life. In addition, although Chinese singles have a high level of interest in health, they have an overall high level of satisfaction regarding fast food and its nutritional value. CONCLUSIONS: The number of singles in Korea, Japan, and China has been consistently increasing in recent years, and there is a need for continuous interest in their healthy dietary lifestyles in terms of convenience, economy, and taste.

Possible correlations between nutrient intake add health status-as assessed by anthropometric measurements, physical performance and biochemical measurements-were investigated, using 514 healthy young men aged 20 years old who had no apparent health problems. The intakes of nutrients were estimated using a three-day dietary recall method. Height and body weight were measured, and body mass index (BMI) was calculated. Physical performance was tested using sit-ups, push-ups, a loom sprint and a 1,500m run. When compared with the Korean recommended dietary allowances (Korean RDA), the subjects nutrient intakes were adequate except for calcium. The intake of calcium was 516.66$\pm$293.43mg/day, which is 73.80 % of the Korean RDA. The subjects averaged 174.51$\pm$7.07cm in height, 68.17$\pm$9.25 kg in body weight and 22.23$\pm$2.16 in BMI. The associations between nutrient intakes and anthropometric measurements, and between nutrient intakes and physical performance, were weak. The intake of vegetable fat was positively correlated to body weight, whereas the intake of carbohydrate was negatively correlated to BMI. The intake of carbohydrate was positively correlated to the level of performance in the loom sprint, and the intake of vegetable Int was positively correlated to the level of performance of sit-ups. No correlation was found between nutrient intakes and the following biochemical measurements of the blood: the levels of glucose, total protein, total cholesterol, triglyceride, hemoglobin and hematocrit. These results suggest that anthropometric measurements and level of physical performance can be associated with energy nutrient intakes, even in moderately active, well-nourished, young men. No correlation was found between nutrient intake and biochemical measurements, probably because all subjects had a reasonably well-balanced diet.

BACKGROUND/OBJECTIVES: Urbanization and lifestyle changes have resulted in nutrition transition. Over-nutrition causes obesity increase, although malnutrition still exists. This phenomenon is called a double burden of malnutrition (DBM). This study was conducted to confirm the existence of DBM and to investigate the dietary factors related to DBM in Indonesian adults. SUBJECTS/METHODS: Data for the subjects (51 men and 89 women) who are the adults resided in Malang, Indonesia were collected between July 17 and August 14, 2017, by using questionnaire. Height, weight, waist and hip circumference, blood pressure, blood glucose, total cholesterol, and hemoglobin were also measured for the subjects. RESULTS: The average age of the subjects was 47.2 years. The average height, weight, and body mass index for men were 160.08 cm, 62.6 kg and $25.45kg/m^2$, respectively, and those for women were 148.74 cm, 58.09 kg, and $26.21kg/m^2$, respectively. Of the subjects, 3.6% were underweight, 24.3% were normal or healthy weight, while 72.2% were overweight and obese. Analysis of the dietary intakes revealed high for cereal (7.73 points), but very low for milk (0.25 points) and fruits (0.51 points). Dietary diversity was very few overall (< 5). The occurrence of both anemia (23.6%) and chronic diseases such as hypertension (57.1%), diabetes (12.1%), and hypercholesterolemia (3.6%) was considerably high. The existence of DBM was confirmed by 16.4% of the subjects. DBM was observed significantly higher in women than in men. Dietary diversity and DBM occurrence were inversely correlated. On average, the number of chronic diseases was 1.08 in men and 1.79 in women. Dietary diversity inversely affected systolic blood pressure. CONCLUSIONS: DBM existed in adults in Malang, Indonesia due to inadequate dietary intakes, and a high rate of chronic diseases.

In order to isolate and identify Bifidobacterium spp. that originated in Korea, feces were sampled from healthy Korean adults and children living in three villages, the first having a history of longevity and the other two where the diet did not include fermented milk or any pharmaceutical preparations. Through the use of Gram staining and microscopic examination for cell morphology, 23 bacterial strains presumed to be the Bifidobacterium genus were isolated from the feces of 13 out of a total of 59 Korean people. To identify the Bifidobacterium strains at the genus level, these bacteria were then analyzed by TLC and the fructose-6-phosphate phosphoketolase (F6PPK) test. The result showed that 22 of the isolated strains were confirmed to be members of the genus Bifidobacterium. All of these bifidobacteria were also identified as Bifidobacterium spp. by the fermentation test. Using a RFLP analysis, an attempt was made to identify the Bifidobacterium spp. that had been isolated from both Korean adults and children. In a genomic Southern blot analysis after digestion with two restriction enzymes (EcoRI, HindIII), all of the 14 randomly selected Korean isolates showed patterns identical to those of three different B. longum species. Another restriction enzyme, CfoI (4-bp recognition enzyme), was then used to identify the strain. Interestingly, all the Korean isolates were identified as B. longum ATCC 15708, indicating that a RFLP analysis was effective for identifying Bifidobacterium spp. at both the strain and species levels.

Objective : Methods of Jang Cong-zheng's treatment related to his theories include of promoting the sweating-vomiting-purgation(汗吐下三法), prickling-bleeding method(瀉血療法), and emotional therapy(情志療法). He succeeded Liu wan-su(劉完素) as promoter of fire-heat pattern theory(火熱論), thereby emphasizing six qi(六氣), especially fire(火) and dampness(濕), as pathogens. He suggested that physician should treat patients whose diseases occurred due to fire(火) and dampness(濕) with promoting the sweating(汗)-vomiting(吐)-purgation(下) methods, which would remove pathogen qi(邪氣) and help circulation of qi and blood, therefore getting them back healthy qi(正氣). Method : I will try to describe the Jang Cong-zheng's treatment in "Ru-Men-Shi-Qin", and I would like to explain the sweating-vomiting-purgation(汗吐下三法), prickling-bleeding method(瀉血療法), and emotional therapy(情志療法). Result : For emotional diseases, he suggested that most should be caused by heart fire(心火) so they should be treated with methods of suppressing heart fire and medication would be using cool and cold herbal drugs which lead to clear heart fire. Conclusion : Theories of Zhang zi-he(張子和) can be applied to nurturing for modern world maintaining and improving health by his care methods. People these days suffer usually from excess intake or unbalanced diet problem, so wastes matter and pathogenic qi can be driven out of the human body by applying the sweating-vomiting-purgation methods. His medical theories could contribute to modernization of traditional medicine this way.

Atopic dermatitis(AD) is a chronic disease that affects the skin. "Atopic" refers to a group of diseases where there is often an inherited tendency to develop other allergic conditions, such as asthma and hay fever. In AD, symptoms vary from person to person. The most common symptoms are dry, itchy skin and rashes on the face, inside the elbows and behind the knees, and on the hands and feet. Although AD may occur at any age, it most often begins in infancy and childhood. The cause of AD is not known, but the disease seems to result from a combination of hereditary and environmental factors along with malfunction of the body's immune system. In contrast to that, the results from literatual study in oriental medicine are as follows; 1. The causes of AD are considered to be Mosusigisadok(母受時氣毒), Waegampoongsubyeol(外感風濕熱), Guasiksinlayeolmul(過食辛辣熱物), Ohbokonje(誤服溫劑). 2. The symptoms are fever, flushed face, red eyes, oliguria, constipation and itching. 3. Chungyeolhaedok(淸熱解毒) would be the basic method of treatment, and it divides into two categories; Subhyung(濕型) and Gunhyung(乾型). In Subhyung(濕型), AD is treated by Josub(燥濕), Chungyeol(淸熱) and Jiyang(止痒) whereas Chungyeol(淸熱), Jiyang(止痒), Jesub(除濕) in Gunhyung(乾型). 4. To prevent further damage and enhance quality of life, it is necessary to keep the temperature and humidity favorable, and healing the skin and keeping it healthy are important. Developing and sticking with a daily skin care routine is critical to preventing flares. Changing the diet and psychological stability may also be helpful to relieve symptoms of AD.

Objectives: The purpose of the this study was to evaluate lifestyle intervention program for the treatment of the metabolic syndrome. Methods: Subjects of this study were 700 adults with metabolic syndrome who took health examinations in health promotion centers of Korea Association of Health Promotion between May 1 and June 30, 2006. Subjects were randomly assigned to an experimental group and a comparison group. Participants in the experimental group received intensive 3-month lifestyle modification intervention and participants in the comparison group received minimal information on lifestyle modification. Pre test and Post test were carried out to evaluate the effectiveness of the intervention program. Results: After the intensive intervention on lifestyle modification(healthy diet, physical activity, moderate drinking, stress management, and smoking cessation), the levels of blood pressure, waist circumference, fasting blood glucose and triglycerides were significantly reduced for those in experimental group(P<0.001). For those in comparison group, the levels of blood pressure(P<0.001), waist circumference(P<0.001), and triglycerides(P<0.01) were significantly reduced after the intervention. No change in the levels of high-density lipoprotein cholesterol were observed in both groups. After 3-month intervention, the prevalence of metabolic syndrome was reduced to 35.7% in experimental group and 48.5% in comparison group. Conclusion: This study has demonstrated the efficacy of therapeutic lifestyle intervention for the management of metabolic syndrome.

Purpose: This study was conducted to estimate the prevalence rate, and related factors,of fatty liver in male industrial workers. Method: Fatty liver was diagnosed using ultrasonography. The data for abdominal ultrasonography, BMI, smoking, alcohol drinking, exercise, liver enzymes, and lipid profiles were collected in 4,604 male who were examined with a health screening program in 2005. Prevalence rate and associated factors of fatty liver were analyzed using SPSS v. 12.0. Results: Overall prevalence of fatty liver was 34.1% and higher in the 30-39 year male group. Age, body mass index(BMI), hypertriglyceridemia, hypercholesterolemia, HDL cholesterol, r-GTP level were independently associated factors with presence of fatty liver in logistic regression analysis. Conclusion: The prevalence of fatty liver and tendency of associated factors were similar to those in the western world. To prevent development of this hepatic disorder, which may result in end-stage liver disease, risk factors such as obesity and dyslipidemia must be monitored and controlled within normal levels. The results of this study suggested maintenance of a healthy lifestyle, including diet, exercise, and behavioral change, as fundamental rehabilitation nursing implications.
