The purpose of this study was to investigate the preference of plant environmental images for flower plant consumption. This study came up with a total of four treatments including one image without plants and three images with flower plants (three roses, rose gift, rose garden). We conducted a survey on 104 men and women through the Google (online) survey and analyzed the data. The preference was higher with statistical significance for environmental images with plants than the image without plants. The preference for environmental images of roses was highest in the order of rose gift > rose garden > three roses. As a result of the cross-tabulation analysis, it was found that there was a significant difference in the preference for environmental images of roses according to general characteristics such as educational background and residence type. In terms of educational background, 2-year college graduates showed higher preference for the three environmental images of roses with statistical significance compared to high school graduates, university graduates and masters or higher. As a result of determining the difference in preference according to residential types, residents of multiplex houses showed higher preference for the "rose garden" environment image than residents of detached houses (p < .05). As a result of examining stress and depression in everyday life, 48.1% (the highest) of the respondents answered that they were "under daily stress" and 48.1% (the highest) of the respondents claimed not to be "under much depression". This study investigated the difference in preference according to demographic characteristics and existence of plants, preference in environmental images using roses, correlation with daily stress and depression, and utility of publicity using photographic images of plants.

A numerical analysis of essential amino acid pattern of protein in daily Korean foods was conducted through computer programming based on the food intake data from 'Reports of national nutritional survey (1969, $1973{\sim}1979)'$ and food supply data from 'Food balance sheet $(1970{\sim}1977)'$. It was noted that the amounts of daily intake and supply of animal protein were gradually increased since 1973. In 1977, animal protein intake was 17.5g in total protein intake of 68g per person per day. Intake and supply of total essential amino acids were $20{\sim}28g$ per person per day in the both of urban and rural areas, and greater consumption of leucine, phenylalanine+tyrosine, isoleusine, lysine and valine was observed. Amino acids scores of consumed protein based on FAO provisional amino acid scoring pattern(1973) were around $75{\sim}90$ showing the scores of 77.9 in 1969 and 89.5 in 1977, and also lysine(1969, $1973{\sim}1976$) and threonine(1977) were considered as first limiting amino acid. On the other hand the scores of supply Protein $(1970{\sim}1977)$ rated in $82{\sim}88$, lysine$(1970{\sim}1971)$ or threonine $(1972{\sim}1977)$ was found as first limiting amino acid. Generally a protein quality of Korean daily food was improved since 1973 and a difference between urban and rural areas in terms of the nutritive quality of protein was considerably reduced in 1977.

The purpose of this study was to estimate the daily manganese (Mn) intake of Korean children. This study was done using a three-day dietary intake survey of 257 Korean children (boys 123; girls 134). The Mn intake values were calculated based on a database that provides the Mn content of the frequently consumed Korean foods, alongside the food composition table provided by the Korean National Rural Living Science Institute. The average age, height, weight and body mass index of our subjects were 11.9 years, 155.4 cm, 48.9 kg and 20.2 kg/$m^2$ in boys and 11.9 years, 154.1 cm, 43.5 kg and 18.3 kg/$m^2$ in girls. The average daily energy intakes were 2,249.2 kcal in boys and 2,044.5 kcal in girls. Boys consumed significantly more Mn than girls, based on intake estimates of $4,585.3{\mu}g$ (117.6% of adequate intake) and $4,029.3{\mu}g$ (117.1% of adequate intake), respectively (P < 0.001). Boys had a Mn intake of $2,041.1{\mu}g$ per 1,000 kcal of energy consumption, whereas for girls this was at $1,983.9{\mu}g$ per 1,000 kcal. Neither group exceeded the tolerable upper intake level for Mn. The major food groups which contributed to Mn intake in our subjects were cereals (50.8%), vegetables (21.0%), seasonings (8.9%), and pulses (7.7%). Notably, boys derived a higher Mn intake through cereals and vegetable than did girls (P < 0.001, P < 0.05). The key food sources of Mn, in descending order, were rice, soybean curd, kimchi, black rice and cereals. We propose that the results of our study may be used as a basis for follow-up studies that examine the Mn intake of children.

The purposes of this study were to estimate nutritional intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 300 elederly people of age over 85 years living in Kyungpook Sung-Ju area who had no problem in daily living. Four times of food consumption survey were carried out seasonally by the repeated 24-hr recall method for one year. Mean daily energy intakes and RDA percentage of energy intakes of the male and female subjects were estimated as 1222 kcal(67.9%) and 1047 kcal(65.4%) respectively. Mean daily intakes of nutrients were estimated as 38.3g for protein, 287mg for calcium, 5.8mg for iron, 314R.E. for vitamin A, 0.6mg for vitamin B1 and 0.43mg for vitamin B2 The mean RDA percentages of nutrients intake were 64.4% and 59.8% for protein in male and female, 39.8% for Ca, 48.3% for Fe, 44.9% for vitamin A, 60% for vitamin B1, and 35.8% for B2. The average PFC ratio of energy-yielding nutrients throughout the year in male and female were 15.1 : 15.2 : 69.7 and 13.8 : 13.2 : 73.0 respectively. The mean daily intakes of energy and most of nutreints were significantly high in winter season. The contribution of plant food sources to nutrient intakes were over 60% for protein and fat, 50% for calcium, and 70% for iron. Long-lived elderly people an Sung-Ju, Kyungpook showed considerably smaller physiques compared to the avergae Korean elderly, however their average BMI fell in normal range. The subjects were consuming much less energy and nutrients compared to the present Korean RDA for the elderly over age 75. The subject showed relatively good health state in spite of low intakes of energy and nutrients. Therefore it seems to be necessary to establish a set of new RDA for the elderly over age 8.5.

본 연구는 스마트폰이 여성의 일상생활 속에서 어떠한 역할과 의미를 갖는지 탐구하기 위해, 20대 중국 여성에 대한 심층인터뷰를 실시했다. 연구결과, 스마트폰은 중국 여성의 소비활동, 여가활동, 사회적 교류활동 등 일상의 다양한 영역에 영향을 미치고 있었다. 여성 이용자들은 스마트폰을 통해 소비습관이 바뀌었으며, 다양한 애플리케이션 활용을 통해 많은 여가시간을 보내고 있는 것으로 나타났다. 그러나 구매상품, 검색정보, 콘텐츠 선택 등에 있어서는 소위 여성영역의 소프트웨어를 선택하고, 이러한 선택에 그들의 성역할이 반영되고 있는 것으로 나타났다. 또한, 여성 이용자들은 SNS를 정보이용이나 단순한 커뮤니케이션 수단으로 활용할 뿐, 자신의 의견제시 등의 참여에는 소극적 태도를 보임으로써 남성과는 달리 수동적인 이용행태를 보였다. 즉 여성들의 스마트폰 이용은 활발하지만, 콘텐츠의 선택이나 이용방식에 있어서는 성별화된 특성과 사회의 젠더가치가 재생산되고 있는 것으로 나타났다. 아울러 본 연구는 스마트폰이 일상화됨에 따라 우리생활에 어떤 변화를 가져오는지를 살펴본 것으로, 특히 스마트폰 강국으로 떠오르는 중국의 사례를 통해 앞으로 국내의 상황을 가늠해보는 중요한 단서를 제공한다고 할 수 있다.

This study was performed to investigate the correlations among physical anthropometric measurement, diet intakes, physical fitness test, and serum lipids in eight sedentary women(control group), and twenty seven exercising women(aerobic groups), aged 35~45 years. The results of the study are as follows : 1) systolic blood pressure(SBP) and diastolic blood pressure(DBP) of aerobic groups were lower than serf entary. Pulse rate was decreased according to the length of aerobic periods. Muscular endurance and jump power of all subjects were stronger than standard range, and those of aerobic exercising groups were stronger than control group. Muscular power of the upper half of the body In all subjects were lower than standard range. 2) Daily calorie intakes of all subjects were in the ring: of recommended dietary allowances (RDA) for Koreans. But daily protein Intakes were higher than RDA. daily cholestrol intakes of all subjects were slightly less than 200~300 mg: which is normal consumption of Koreans. 3) There was a significant positive correlation between serum 7G and daily protein intakes. It was considered that excessive protein intake converted to serum 7G. There was not a significant correlation between serum TC and dietary TC. Therefore, dietary TC seemed to have not much effect on serum TC. Physical fitness was negatively related to serum TG, TC, LDL-C, but positively related to HDL-C, HDL-C /TC. It was found that the serum lipids could be changed better according to improving the physical fitness. There were significant positive correlations between SBP and serum TC, LDL-C. (According to this results), the higher SBP, the higher serum TC, LDL-C tended to be. There was a significant positive correlations between sit up and weightloss nth exercise r=0.7(p<0.001), push ups and weightless with exercise r=0.5(p<0.001). It was considered that muscle strength could be improved according to the weightloss. 4) The purpose of exercise in aerobic groups was rather promoting health than reducing body fatness. Most of al1 subjects (83.2%) drank caffeine-contained beverage therefore, we should concern about that absorption of Fe could be Interrupted and blood pressure could be elevated by caffeine.

Flavonoids are phytochemicals that occur ubiquitously in plant foods that have been reported to have potential roles in the prevention of cancer, inhibition of platelet aggregation or inflammation. However, there was no accurate data reported on the intake of middle-aged Korean population. The present study was designed to assess dietary intake of flavonoids (including isoflavones) of 304 adults (20-59 yr, male 115, famale 189) living in Daejeon area using semi-quantitative food frequency questionnaire. The questionnaire consisted of 50 food items, including vegetables, soy products, seaweeds, nuts and beans, fruits and beverages. Our self-administered questionnaire contained questions regarding subject's habitual diet and alcohol intake over the previous 3 months. Average daily intake of individual flavonols such as quercetin, kaempferol, myricetin, and flavones such as luteolin, apigenin was 15.7, 8.7, 0.21, 2.07, 0.03 mg/day, respectively. Daily intake of daidzein and genistein, which are the commonly found isoflavones in soy products, were 16.6 and 21.4 mg/day, respectively. Combined intake of flavonoids was 64.3 mg/day. No effect of smoking, drinking and exercise was observed on flavonoids consumption. Food items that has the highest daily intake of each compounds were; quercetin (onion, 9.49 mg/day), kaempferol (strawberry, 1.18 mg/day), myricetin (green tea, 0.81 mg/day), apigenin (lettuce, 0.03 mg/day), luteolin (onion, 0.05 mg/day), daidzein (soybean sprout, 5.99 mg/day), genistein (soybean sprout, 7.02 mg/day). These findings provide valuable information on understanding the dietary flavonoids intake from a typical Korean daily diet, which might help to identify the risks for developing various diseases.

The purpose of our study was to evaluate an association between milk consumption and bone mineral density (BMD) of female college students in Korea. The dietary data of 1,410 Korean college students living in the vicinity of Seoul area were collected through the Food Frequency Questionnaire. The mean age, height, weight and 8MI of the subjects were 20.4 years, 162.1 cm, 52.7 kg, and $20.0\;kg/m^2$ respectively. The mean intakes of energy, protein, and phosphorus were 2,398.7 kcal, 95.2 g, and 1,302.9 mg respectively, which were above their EER or Recommended Intake (RI), but the mean intake of calcium was 657.8 mg which was below its RI, and 44.0% of the subjects did not meet Estimated Average Requirement (EAR) of calcium. The daily milk consumption was 131.1 g, and the total consumption of milk and dairy product was 228.7 g. Forty five percent of the subjects consumed $50{\sim}200\;g$ of milk or dairy products. After the analysis of their dietary intakes, the subjects were divided into quintiles of total consumption of milk and dairy product, which were considered as major source of dietary calcium. Ninety two subjects from the upper quintile (UQ) and 85 subjects from the lower quintile (LQ) were selected and their bone mineral densities (BMD) of lumbar spine (L1-L4) and the femur were examined by the dual energy X-ray absorptiometry. The BMD $(g/cm^2)$of L1, L2, L3, and average of femur were 1.065, 1.150, 1.187, and 0.988 for the UQ subjects, which were significantly higher than those of the LQ subjects, 1.010, 1.090, 1.146, and 0.942 respectively. Moreover, the T-scores of the UQ were significantly higher than those of the LQ. The prevalence rates of osteopenia classified according to WHO's criterion were 12.0% in the UQ. and 20.0% in the LQ group which showed non significant. Blood levels of calcium, and phosphorus of UQ and LQ group were both within the normal range, and were not significantly different. Our results showed that UQ group presented the better status of bone mineral density and bone health. Therfore our results suggest that continuous consumption of more than one and a half cups of milk per day, which corresponds to the least amount of UQ group's consumption, would affect positively on the bone health of Korean adults.

A dietary intake survey in 2 major city area was conducted as a part of the study which determined the level of exposure of people to harmful substances in foodstuff. A total of 800 randomly selected men and women aged 20-49 yr and living in the cities of Seoul and Taegu were invited to participate in the survey. All subjects were interviewed by trained dietitians to answer for demorgraphic characteristics and dietary intake for 1 day by 24hr recall method, and asked to record what day ate for following 2 more days by themselves. Results were analyzed and presented for the amount and frequency of food intake by area, sex body weight. Food consumed most by adults resifing in these 2 city area was rice and followed by kimchi in the amount of 225.7g/persn/day and 85.0g/person/day, respectively. In the list of foods consumed most frequently, items used for condiments were included in addition to rice and kimchi. And the total daily intake of food per person was summed up to be 1, 534g for men and 1, 304g for women. Considerable part of this sexual difference in total intake was originated from the difference in beverage consumption including alcoholic beverages and the higher intake of certain foodstuff due to higher body weight of men. Intake data were presented din terms of per capita and per kg body weight, and compared among adults in different categories of body weight, also. The data gathered here, food intake by individuals, reflect our own dietary culture in terms of food assortment and relative contribution of each food item to total food intake include the consumption of "extreme" eaters might be found useful also especially for the sake of food safety such as risk assessment using ADI and PTWI for contaminants in the food supply.od supply.
