Various types of dried laver Pyropia yezoensis have been produced in response to increasing demand and other laver goods manufactured using different processing methods are continuously being developed. The dried laver used in this experiment was initially heated at $165^{\circ}C$ for 3 seconds, followed by second heating at a high temperature ($340-350^{\circ}C$) to increase the storage period and enhance taste and flavor. Nutrient analysis of each sample heated under three conditions revealed that the protein and lipid contents were highest in samples from D company, while the carbohydrate contents remained relatively stable. After storage for 10 weeks at room temperature, changes in the composition were evaluated. The results showed decrease in protein (30%-49%) and essential amino acid contents. During storage, the major unsaturated fatty acids contained in dried laver slightly changed to 53.4%-56.0% in the form of EPA, while saturated fatty acids slightly increased to 18.4%-22.6% in the form of palmitic acid. The variables derived from fatty acid composition, such as atherogenic and thrombogenic, and hypocholesterolemic/hypercholesterolemic dietary indices, and polyunsaturated fatty acids/saturated fatty acids ratio, also indicated reasonable levels of stability. However, the laver should be consumed within 2 months.

The purpose of this survey was to investigate the nutrient and food intake and food habits of the aged Jeju island. The survey was conducted to 102 persons, 50 persons aged 65 to 74 years and 52 persons aged 75 years over from July 5 to 25, 1981. The result obtained was summarized as follows; 1. Average nutrient intake per day Calorie intake was 1408 ㎉(which was 64% of RDA) for male and was 1343 ㎉ (84%) for female aged 65 to 74 years. For male aged 75 years over calorie intake was 1316㎉ (60%) and for female was 1292㎉ (81%). According to the intake of calorie, the ratio of carbohydrate, protein, fat, were average 74.8%, 15.1%, 10.1%. Protein intake was insufficient quantiatively, but the proportion of animal protein to total protein intake were 26.1 to 33.5%. Other nutrient intake, such as Ca, vitamin A and C were lower than the recommended dietary allowance. 2. Food intake In per capita food consumption were 69.1g to 744.7g and average 320.1g of cereal (125.1g of rice and 160.5g of barley) and 63.9g of fishes. Total food consumption and vegetables were diminished by older age. 3. Correlation assessment The correlation coefficient between residental stus lived with family, high activity, good health, and nutrient intake were significant (P<0.05). Poor teeth had influence on less nutrient intake, but was not significant. 4. Food preferences Food liked over 70% of subjects were persimmon, fishes, leef, tomato, and boiled rice with barley, etc. owing to tender food, economical reasons, seasonal influence, and food habits. Food disliked over 20% of subjects were instant noodle, small sardin, boiled rice, and ice-crea, etc. The majority of subjects had never had the processing food, such as ham, sausage, butter and margarine, etc.

Background: Dietary fat has been suggested to be the cause of various health issues. Obesity, hypertension, cardiovascular disease, diabetes, dyslipidemia, and kidney disease are known to be associated with a high-fat diet (HFD). Obesity and associated conditions, such as type 2 diabetes mellitus and nonalcoholic fatty liver disease (NAFLD), are currently a worldwide health problem. Few prospective pharmaceutical therapies that directly target NAFLD are available at present. A Traditional Chinese Medicine, ginseng-plus-Bai-Hu-Tang (GBHT), is widely used by diabetic patients to control glucose level or thirst. However, whether it has therapeutic effects on fat-induced hepatic steatosis and metabolic syndrome remains unclear. Methods: This study was conducted to examine the therapeutic effect of GBHT on fat-induced obesity, hepatic steatosis, and insulin resistance in mice. Results: GBHT protected mice against HFD-induced body weight gain, hyperlipidemia, and hyperglycemia compared with mice that were not treated. GBHT inhibited the expansion of adipose tissue and adipocyte hypertrophy. No ectopic fat deposition was found in the livers of HFD mice treated with GBHT. In addition, glucose intolerance and insulin sensitivity in HFD mice was also improved by GBHT. Conclusion: GBHT prevents changes in lipid and carbohydrate metabolism in a HFD mouse model. Our findings provide evidence for the traditional use of GBHT as therapy for the management of metabolic syndrome.

The purpose of this study is to analyze the factors associated with health and diet by nutritional status. The subjects were the children aged 2 to 6. Physicians and nurses measured children's anthropometries and examined their blood and urine. Interviewers questioned children's food habits to their mothers. 24 hour recall was done for children with their mother. The nutritional status was classified to 'underweight', 'normal weight' and 'overweight' by weight for height(median±1 S.D.) of the reference population. The number of subjects in each group(under, normal, over) was 25, 130 and 49. Factors including anthropometry and hemoglobin concentration were not significantly dif ferent by the nutritional status. The birth weight of children was correlated positively to mothers' BMI. Z scores of weight for height were related to the birth weight positively by the analysis of variance. The children of the underweight group used nutritional supplements more frequently than those of normal and overweight group. The nutrient intakes of normal weight group were higher than those of low and overweight group. Particularly, the intakes of energy, carbohydrate and calcium were significantly high among the groups. In terms of number of foods, food groups and dishes consumed per day, the children of the normal weight group ate more diversely than other groups but the differences were not significant. In conclusion, the children of normal weight group had similar characteristics with other groups but had more desirable dietary intakes than other groups in this study. Because the diet of children may be different by the nutritional status, nutrition education for children should be conducted according to the characteristics of each group's diet.

Purpose: This study aimed to identify the effects of nursing intervention programs for women with gestational diabetes mellitus (GDM) through a critical review of recent studies. Methods: Studies related to effects of nursing intervention programs for women with GDM published in English or Korean between 2000 and 2019 were extracted from 10 electronic databases. The quality of the studies was evaluated and double-checked for accuracy by two reviewers using the Revised Cochrane Risk-of-Bias tool for randomized controlled trials. Results: Twenty studies were selected, of which 19 had a low risk of bias and one had a high risk of bias. Interventions fell into six main groups: (1) integrated interventions, (2) self-monitoring of blood glucose levels, (3) dietary interventions, (4) exercise, (5) psychotherapy, and (6) complementary therapy. This review found that nursing interventions for GDM were of many types, and integrated interventions were the most common. However, low-carbohydrate diets and blood glucose monitoring interventions did not show statistically significant results. Evidence shows that various nursing intervention programs applied to GDM improved diverse aspects of maternal, fetal, and neonatal health, including both physical and psychological aspects. Conclusion: The composition and delivery of integrated interventions continue to evolve, and these interventions affect physical and psychological indicators. Although interventions affecting physical health indicators (e.g., blood glucose levels, diet, and exercise) are important, many studies have shown that programs including psycho-emotional nursing interventions related to anxiety, depression, stress, self- efficacy, and self-management are also highly useful.

본 연구는 2001년 국민건강 영양조사 자료를 이용하여 초 중 고 학령 어린이를 가구 소득 수준에 따라 저소득가정 어린이와 일반가정 어린이로 분류한 후 신체계측자료 및 영양소와 주요 식품군의 섭취수준을 학령군별로 비교 평가하였다. 주요 결과를 요약하면 다음과 같다. 1) 저소득가정 어린이들과 일반가정 어린이들의 학령군별 연령수준과 성별분포는 유의한 차이를 나타내지 않았다. 2) 저소득가정 어린이들의 신장, 체중, BMI는 일반가정 어린이들보다 전반적으로 낮은 경향이었으나, 이러한 차이는 중학생 학령군의 체중과 BMI에서만 통계적으로 유의하였다. 체중평가 결과의 분포를 비교한 결과, 저체중 또는 과체중의 비율이 두 소득계층간에 유의하게 다르지 않았다. 3) 에너지 섭취수준에는 소득계층에 따른 차이가 나타나지 않았으나, 저소득가정 어린이의 경우 일반가정 어린이 보다 탄수화물에서 섭취하는 에너지 비율이 높고 지방에서 섭취하는 에너지 비율은 낮았다. 4) 일부 미량영양소의 경우, 저소득가정의 초등학생과 중학생 학령군의 평균 섭취수준이 일반가정 어린이들보다 낮았으며, 초등학생 학령군에서 이러한 차이를 보이는 영양소의 수가 더 많았다. 5) 식사구성안을 기준으로 여섯 가지 식품군에 대한 섭취수준을 평가하였을 때, 초등학생 또는 중학생 학령의 저소득가정 어린이들의 경우 우유 유제품과 과일의 평균 섭취수준이 일반가정 어린이들보다 낮았고, 또한 권장 수준보다도 낮은 수준이었다. 중학생과 고등학생 학령의 저소득가정 어린이의 경우, 고기 생선 계란 콩류의 평균 섭취수준이 일반가정 어린이보다 낮았고 이 또한 권장 수준보다 낮았다. 결론적으로 식품섭취 수준에서 본 우리나라 저소득가정 어린이의 식생활 문제는 일반가정 어린이와 공통적 요소를 가지고 있었으나, 그 심각성은 상대적으로 큰 것으로 나타났다. 즉 우유 유제품 및 과일의 섭취 부족은 소득 계층에 관계없이 학령기 어린이의 공통된 식생활 문제로 분석되었으나 이러한 문제가 저소득계층에서 더욱 심화된 양상이었다. 또한 일부 학령군의 저소득가정 어린이는 일반가정 어린이에게서는 발견되지 않는 특수한 식생활 문제로서 고기 생선 계란 콩류의 섭취 부족이 나타났다. 따라서 학령기 저소득층 어린이의 식생활 문제의 해결을 위해서는 일반 어린이와는 다른 접근방식의 보다 적극적인 지원 정책이 필요하며, 기존의 관련 정책 및 사업 또한 이러한 특수성을 고려한 개선이 시급하다. 저소득층 어린이들의 학령군에 따른 상이한 식생활문제 또한 이러한 정책 내용에 반영되어야 할 것이다.

This study was conducted to examine bone mineral density and factors which effect on bone mineral density such as daily nutrients intake, age, menarch age and physical condition among healthy female college students in Daegu area from April 20, to May 20, 2004. 1. Average age was 20.5$\pm$0.96 years old, average height was 160.9$\pm$4.30㎝, and average weight was 55.9$\pm$7.67㎏. Body mass index was 21.6$\pm$2.91㎏/㎡, body fat was 25.6$\pm$5.79％, menarche age was average 12.5$\pm$1.1 years old and WHR(waist/hip circumference ratio) was 0.8$\pm$0.01㎝/㎝. 2. Average level of bone mineral density(T-score -0.56$\pm$0.91) was in normal range. But, 11 persons(24.4％) are over T-score -1.0, 33 persons(73.4％) were within -1.0 - -2.5 and one person(2.2％) was under -2.5. It is very anxious level for Osteopenia-low bone mass, as research result shows 73.4% of the subject of examine on the level of Osteopenia. 3. Daily calorie intake was 2,550㎉ and each nutrient intake, compared to the seventh recommended dietary allowances for korean, was as follows ; Calorie 112％, protein 123％, calcium 78％, phosphorus 137％, iron 68％, vitamin A 101％, vitamin $B_1$ 141％, vitamin $B_2$ 95％, niacin 107％, vitamin C 128％ and zinc 120％. The ratio of calcium to phosphorus(Ca/P) is 0.66, low compared to RDA, but phosphorus intake is so high compared to RDA that precautions should be taken. The ratio of calcium to protein(Ca/Protein) is 8.55. 4. Menarche age and bone mineral density of calcaneus showed positive correlation and body mass index(BMI) indicated positive correlation. Age, height, weight. WHR and physical activity coefficient all do not indicate any significant correlation with bone mineral density. 5. Intake of Calorie, Ca, Ca/p ratio, carbohydrate and fat intake were positively correlated and, protein was negatively correlated, and Fe, Na, P and cholesterol were negatively correlated with BMD. These results indicate that average bone mineral density of subjects was in normal range, but subjects in the stage of osteopenia-low bone mass are many and bad effects are expected to have on their bone mineral density after menopause. Therefore, in order reach maximal bone mineral density, they should improve the balance between calcium and phosphorus and reduce salt intake. And it is thought that education and profound studies on relevant factors affecting the genesis of bone mineral density should be made.

As the severity of environmental pollution increases, the foodstuffs are contaminated more the ever. There are 40 kinds of heavy metals that we are able to consume through the heavy metal contaminated-foodstuffs. Arsenic, lead, cadmium, and chromium out or them have been know to be a potential cause for a alzheimers disease, kidney diseases, and cancer. However, research data on the daily intakes of such heavy metals are limited. This study was performed to evaluate the daily intakes of nutrients and the dietary heavy metals of the college women living in Choongchung-NamDo Area, where had been reported to have high contents of heavy metals for the seafoods. We also investigated the blood levels of the heavy metals. The mean age, height, weight, BMI and percent ideal body weight(PIBW) of the subjects were 20$\pm$1.0yr, 158.4$\pm$0.7cm, 55.1$\pm$1.4kg, 22.4$\pm$.04, and 103.3$\pm$2.5 %, resp-ectivly. The mean of daily energy intake was 1,717.03$\pm$55.99kacl/day(86% of RDA for women). The ratio to energy from carbohydrate, fat and protein was 60: 24: 16. Daily intakes of Vit A, Vit B$_2$, CA, and Fe were under the RDA for those nutrients. The mean adequate ratio of the subjects was 0.92 . The daily intakes of heavy metal, such as As, Pb, Co, Cr and Mn , were 1.80$\pm$0.27mg, 75.21$\pm$4.12$\mu\textrm{g}$, 21.12$\pm$12.34$\mu\textrm{g}$, 60.07$\pm$6.24$\mu\textrm{g}$ and 6.23 $\pm$0.12mg respectively. the blood levels of As, Pb, Co, Cr and Mn were 16.10$\pm$2.10$\mu\textrm{g}$/dl, 4.32$\pm$0.58$\mu\textrm{g}$/dl, 0.02$\pm$0.01$\mu\textrm{g}$/dl, 4.23$\pm$0.41$\mu\textrm{g}$/dl, and 4.40$\pm$0.21$\mu\textrm{g}$/dl, respectively. In conclusion, daily intake of heavy metals for the college women living in Choongchung-NamDo area was lower than that of WHOs re-commendation, however, the blood levels of each heavy metals were higher than those of Japanese, american, and italian, There were no correlations between the dietary intakes and blood levels of each heavy metals.
