Objectives: The purpose of this study was to compare the sex-associated differences in the dietary intake of gastric cancer patients in Korea. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHANES) the 7^th (2016-2018) were analyzed in the present study. The subjects included 122 gastric cancer patients aged over 40 years (75 male, 47 female). General characteristics (age, marital status, household income, education, food security, comorbidities, alcohol drinking, and smoking), anthropometric characteristics (height, weight, body mass index, and blood pressure), blood biochemical characteristics [fasting plasma glucose (FPG), blood urea nitrogen (BUN), creatinine, triglyceride, total cholesterol, and HDL-cholesterol)], and quantity and quality of dietary intake were compared between male and female participants. Results: Males had higher rates of having a spouse, prevalence of hypertension, alcohol drinking, and smoking than females. The proportion of males with a normal range of FPG, BUN, and HDL-cholesterol was lower than that in females. The total cholesterol levels above the normal range were higher in females than in males. We also found that females had a higher percentage of intakes below the estimated energy requirement (EER) and intakes below the estimated average requirement (EAR) for carbohydrates, niacin, phosphorus, and iron than males. The index of nutritional quality (INQ) for phosphorus and folate, nutrient adequacy ratio (NAR) for vitamin C, thiamine, niacin, folate, calcium, and phosphorus, and the mean adequacy ratio (MAR) were lower in females than males. Conclusions: In Korean gastric cancer patients, management of comorbidities such as diabetes and hypertriglyceridemia, lowering FPG, and raising HDL-cholesterol level management is required for males, whereas management of lowering total cholesterol and raising hematocrit is required for females. The quantitative and qualitative nutritional intakes were poor in gastric cancer patients, especially in females, who had a lower nutritional intake than males. We suggest that nutritional interventions are needed to improve the overall nutritional intake in both male and female gastric cancer patients. In particular, we propose that support is urgently needed for females whose nutritional intake is lower than that of males. In addition, family, social, and national support for nutritional management of female gastric cancer patients is highly necessary.

According to Hans Kippenberg, the foundation of an academic study of religions coincided with the beginnings of modernization. Since the second half of the nineteenth century most European countries were involved in a process of rapid social change. The repercussions that this had for daily life were momentous. Instead of working for their traditional needs, people now had to produce goods for a market. Old customs ceded to private contracts and political laws. The superior knowledge of science replaced the inherited worldview. This deep changed severed societies from their ties to the past. Many educated people in Europe believed in an imminent end of all religions. Had not the scientific progress superseded the religious worldview? Historians had to come to terms with that expectation when they directed their attention to historical religions. Friedrich Max Muller introduced a new science, so-called Religionswissenschaft through the study of the ancient Vedic sources. He thought that genuine religion was a taste for, and sense of, the infinite. From his point of view, the Indian sources confirm that nature is more than mechanical laws. Thus his interpretation sought to contradict the materialist ideology of his day. Edward Burnett Tylor described religions as a kind of natural philosophy. His notion of 'soul' functioned to explain natural events. This legacy of the past cannot be missed even in modern society. Only the concept of the soul may preserve human dignity in an age of materialism. Gerardus van der Leeuw, also tried to perform the same function of the cultural critique for the renewal of the religious imagination in modern, rationalized Europe imprisoned in the iron-cage. In this respect, we could think that the interpretations of the history of the History of Religions in the light of the intellectual history are very suggestive for the korean student of religion. It helps them to describe the early history of the study of religion in Korea. For example, Yi Neung Wha(李能和) is regarded as 'a father of korean religious studies, but no one could present a proper answer for the question of why and through which connection of his intellectual milieu he was interested in the religious history and the study of religion. We would discover its signification in his confrontation of the prevailing social thought, such as social evolutionism.

Objective: Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow obstruction that is only partly reversible, inflammation in the airways, and systemic effects. This study aimed to investigate the association between low peripheral oxygen saturation levels (SpO₂), and composite indices predicting death in male patients with (COPD). Method: A total of 140 participants with post-bronchodilator FEV₁/FVC ratio less than 0.7 were included. Three composite indices (ADO, DOSE, BODEx) were calculated using six variables such as age (A), airflow obstruction (O), body mass index (B), dyspnea (D), exacerbation history (E or Ex), and smoking status (S). Severity of airflow limitation was classified according to Global Initiative for Obstructive Lung Disease (GOLD) guidelines. SpO₂ was measured by pulse oximetry, and anemia and iron deficiency were assessed based on blood hemoglobin levels and serum markers such as ferritin, transferrin saturation, or soluble transferrin receptor. Results: Participants with low SpO₂ (<95%) showed significantly lower levels of %FEV₁ predicted (p=0.020) and %FEV₁/FVC ratio (p=0.002) compared to those with normal SpO₂ levels. The mMRC dyspnea scale (p<0.001) and GOLD grade (p=0.002) showed a significant increase in the low SpO₂ group. Receiver Operating Characteristic analysis revealed higher area under the curve for %FEV₁ (p=0.020), %FEV₁/FVC(p=0.002), mMRC dyspnea scale (p=0.001), GOLD grade (p=0.010), ADO (p=0.004), DOSE (p=0.002), and BODEx (p=0.011) in the low SpO₂ group. Conclusion: These results suggest that low SpO₂ levels are related to increased airflow limitation and the composite indices of COPD.

This study was conducted to investigate Osteoporosis on the effect of dietary factors and past young age period's dairy products consumption on BMD in 170 postmenopausal Korean women without diagnosed disease. Bone mineral density(BMD) of lumbar spine was investigated by dual energy X-ray absorptiometry. Dietary assesment of the subjects were measured by Cognitive Food Frequency Recall method. The measurements of group average were 57.9kg of body weight, 36.73 of BMI(Body Mass Index), 2103.3㎉ of energy, 638.7mg of dietary calcium, 70.3g of protein, and 10.58mg of iron. Nutrient intake levels were similar to or more than the level of Korean Recommended Dietary Allowances. Bone Mineral Density(BMD) of Lumbar spine(L2-L4) of group average was 0.912g/$\textrm{cm}^2$, and under 50 yr's 1,02g/$\textrm{cm}^2$, 50~54 yr's 0.92g/$\textrm{cm}^2$, 55~59 yr's 0.85g/$\textrm{cm}^2$, over 60 yr's 0.85g/$\textrm{cm}^2$, had been getting low degree on aging. BMD of the Lumbar spine was positively correlated with calorie, body weight, dietary calcium, protein, phosphorus and serum albumin. Past dairy products consumption experiment was highly significant on BMD in teenage period(R square = 26, p-value 0.0031). Particularly in over 60 yr group, the correlations between BMD and past dairy products consumption in teenage period had shown highly significance(r=0.48, p<0.02). 55~59 yr age group had also positive correlation(R squae = 0.29, p<0.05). This results confirm that the most effective way of preventing osteoporosis and the fractures is to maximize peak bone mass in early life and to minimize bone loss through the balanced intake of Ca and other nutrients and regular physical activity.

This study was conducted to evaluate the effects of an abdominal obesity management program on dietary intake, stress index, and waist to hip ratio (WHR) in abdominally obese women. The subjects were 195 adult abdominally obese women (WHR ${\geq}$ 0.80) who had been participating in a nutrition education (total of nine times) and dietary habits and life style modification programs (total of six times) for 12 weeks. The abdominal obesity management program focused on the nutrition provided by breakfast, lunch, and dinner, proper dietary habits, and practices to improve life style. The subjects were divided into a WHR decrease group and a WHR increase group according to changes in the WHR. Daily nutrient intake was assessed with a 3-day food record, body measurements and blood vessel age, stress index, and a health index that were measured at baseline and after 12 weeks. After the intervention, weight, waist circumference, hip circumference, WHR, and body mass index (BMI) decreased significantly in the WHR decrease group. Energy intake increased from 1486.2 kcal to 1541.4 kcal with a significant improvement in nutrient density for animal protein, total fat, animal fat, fiber, calcium, phosphorus, zinc, vitamin $B_6$, vitamin C, vitamin E, and saturated fatty acids in the WHR decrease group. Additionally, dietary diversity increased significantly in the WHR decrease group compared to that in the WHR increase group. The WHR decrease group showed a significant improvement in the stress and health indices. Changes in WHR were correlated with changes in nutrient intake (animal protein, total fat, animal fat, plant fat, fiber, calcium, iron, potassium, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, and folate) and medical index profiles (stress and indices) adjusted for age, birth status, baseline BMI, and baseline WHR. These results show that an abdominal obesity management program was effective not only for reducing the WHR but also to improve dietary intake and the stress index in abdominally obese women.

This study aimed to reanalyze energy and nutrient intakes of 2007 Korean Nutrition and Health Examination Survey (KNHANES) using CAN-Pro 3.0, a commonly used nutrient analysis software in Korea. Food items and their codes were selected from 2007 KNHANES dietary intake file and converted to food codes of CAN-Pro 3.0 nutrient database (NDB). Of the 1,324 total food items, 1,155 items were converted by direct matching, 123 items were matched using other items in CAN-Pro 3.0 NDB and 42 items were matched using external sources. Consumption frequencies of items converted by direct matching contributed 94.5% of total consumption. Nutrient intakes of 4,091 participants of 2007 KNHANES, over 1 year old, were recalculated using CAN-Pro 3.0 NDB and compared with intakes in 2007 KNHANES dietary intake file. Intakes for energy and all nutrients except protein and Vitamin C calculated by two NDBs were significantly different by paired t-test (p < 0.001), but significantly correlated by Pearson' correlation coefficients (p < 0.001). Percent differences between the NDBs ranged from 0.3% to 15.1%, low for protein, energy, vitamin C, iron, vitamin B$_2$ (below 5%) but high for phosphorus, retinol, vitamin A, and $\beta$-carotene (over 10%). Age group, sex, and their interactions significantly influenced six nutrients (p < 0.05). Intake levels of zinc, vitamin B6, vitamin E, folate and cholesterol were not available in 2007 KNHANES but were calculated by CAN-Pro 3.0. Mean intake levels of zinc, vitamin B$_6$, vitamin E, and folate by age and sex groups revealed that some groups had mean levels below RI (Recommended Intake) or AI (Adequate Intake) levels. Intake level of cholesterol was higher than the recommended level (below 300 mg/day) in some groups, especially males. Results of the present study indicate the need for comparable and more comprehensive NDB to be used for dietary assessment of KNHANES and other researches. More rigorous evaluation of nutrients which have not been reported in KNHANES is needed.

Purpose : Vitamin D deficiency rickets is a significant public health problem that results from insufficient exposure to sunlight and inadequate vitamin D supplementation. The purpose of this study is to identify the clinical characteristics of vitamin D deficiency rickets in infants. Methods : Data of 35 infants diagnosed as vitamin D deficiency rickets at Sanggye-Paik Hospital, Seoul, Korea, from March 2007 to May 2009 were reviewed. Children with plasma 25-hydroxyvitamin D levels <15 ng/mL and 15-30 ng/mL were considered to have vitamin D deficiency and vitamin D insufficiency, respectively. Results : Thirty-five infants (22 boys, 13 girls) were diagnosed with rickets. Mean age at diagnosis was $7.4{\pm}7.1$ months (range: 0.1-29.8 months). Eighteen infants (51%) were vitamin D deficient and seventeen infants (49%) were insufficient. Twenty-eight of all (80%) diagnosed as subclinical rickets. Twenty-nine infants (83%) were below the age of 12months. Twenty infants (57%) had breastfed and ten infants (29%) had iron deficiency anemia. Nine of breastfed infants (45%) were vitamin D deficient and ten of their mothers were vitamin D insufficient. Overall, radiographic evidence of rickets was present in 93% of the cases. Radiographic sign of rickets was evident even in vitamin D insufficient state. Conclusion : It is important for the clinician to screen for subclinical vitamin D deficiency rickets in inadequately supplemented infants by pairing 25-hydroxyvitamin D levels with wrist radiographs. A nationwide epidemiological study of vitamin D deficiency rickets must be conducted and evidence-based national guidelines must be defined to prevent rickets.

This study was conducted to investigate dietary and other factors affecting bone mineral density in young Korean collage women. Thirty subjects were recruited; the mean age was 22.1 years and the mean age at menarche was 12.6 years. Bone mineral density (BMD) was measured in the spine (LS), femoral neck (FN), ward's triangle (WT), and femoral trochanter (FT) by Dual Energy X-ray Absorptiometry (DEXA), and physical activity was assessed by a questionnaire. Dietary intake data were obtained 8 times by using a 24 hour recall method to evaluate the subjects' usual diet. Bone mineral densities of lumbar spine, femoral neck, ward's triangle and femoral trochanter were 1.149 g/$\textrm{cm}^2$, 0.980 g/$\textrm{cm}^2$, 0.936 g/$\textrm{cm}^2$ and 0.759 g/$\textrm{cm}^2$ respectively. The met energy intake of subjects was 1,790 kcal, and calcium and iron intakes were found to be inadequate compared to the Korean RDA. The BMD of the lumbar spine was significantly and positively related to the BMI and intake of vitamin C, carbohydrate, potatoes, fruits and plant food. The BMD of the femur (FN, WT, FT) was positively related to the BMI, to carbohydrate and fruit intake, and to the percentage of plant food in total food intake. Multiple recession analysis showed that fruit intake was significantly related to the BMD of the LS. The subjects'ages and fruit intakes were significantly related to the BMD of the femur (FN, WT, FT). These results indicate that higher fruit intakes may have a beneficial effect on bone mineral density.

The purpose of this study is to provide fundamental information for snack development contributing to physical growth of children with cerebral palsy. The study was conducted on the children with cerebral palsy of age 1 to 7 by investigating their food behavior, physical growth development, nutritional status, and snack intake. As a result of assessing physical growth by WLI (Weight-Length Index), the proportions of the children with cerebral palsy were the following: underweight 45.5%, normal 45.5%, overweight 6.0%, and obesity 3.0%. The mothers of the children with cerebral palsy mainly bought milk and dairy products for their children's snacks (43.5%) as well as fruits (33.3%). They wanted development of new snacks that helped growth development (50.5%), and preferred more development of the following snacks: Korean rice cakes (47.5%), biscuits (24.2%), bread (22.3%). The result of dietary intake showed that the percentage of RI in zinc and folic acid did not reach the RI in every age categories. The proportion of subjects with less than 75% of RI was 76.8% for the zinc and folic acid, and 52.4% for the calcium and iron. These results indicate that children with cerebral palsy had slower physical development and lesser nutrition intake than normal children. Hence, this study provided the basis to develop the snack for the malnutrition state children with cerebral palsy which helped their physical development. The shape of new snack considered was a rice cake which included zinc and folic acid that were insufficient in RI in children with cerebral palsy.

Purpose: This study examined dietary and health characteristics of the young-old and the old-old by food security status. Methods: The study used data from the $6^{th}$ (2013 ~ 2015) Korea National Health and Nutrition Examination Survey. The study subjects consisted of 3,948 subjects, of whom 2,445 were the young-old (aged 65 to 74 years) and 1,503 were the old-old (aged 75 years and over). Food security status was evaluated using an 18-item questionnaire. Energy intake, nutrient densities, and prevalence of insufficient nutrient intake were assessed. Food intake was evaluated in terms of the number of food group servings. Dietary behaviors and health status were also assessed. Results: The prevalence of food insecurity among the young-old and the old-old was 10.0% and 11.6%, respectively. Among the young-old, the food insecure group had a significantly higher level of prevalence of insufficient intake for all the nutrients (protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, calcium, phosphorous, and iron) assessed in this study compared with the food secure group. In case of the old-old, significant differences were found only for four nutrients (protein, riboflavin, niacin, and phosphorus) in the prevalence of insufficient nutrient intake between the food secure and the food insecure groups. Kinds of food groups with significantly different numbers of servings by food security status were dissimilar between the two age groups. In both the age groups, the food insecure group consumed a significantly lower number of servings in meat fish eggs legumes and fruits than the food secure group; grains and vegetables intake in the young-old and oils sweets intake in the old-old differed in the number of servings by food security status. Among the young-old, the prevalence of chewing difficulties in the food insecure group was significantly higher than that of the food secure group, while among the old-old, no significant differences were found by food security status. Conclusion: Dietary and health characteristics of the young-old and the old-old differed by food security status. Such differences were more apparent in the young-old than the old-old. Therefore, it is suggested that food and nutrition assistant programs should be designed with consideration of the differences.
