This research was designed to develop a computer program and evaluate the nutritional balances especially the balance of fatty acids, amino acids and antioxidant vitamins for convenience foods. The Korean convenience food, Kimbab purchased from markets was evaluated by using the self-developed computer program. Contents of calories, protein and calcium were lower$(1/3^{\circ}{\neq}1/2)$ than the recommended levels of Korean adult woman, and the carbohydrate/ protein/ fat(CPF) energy ratio was 70: 13: 17. The mean P/ M/ S ratio was 2.2/ 1.4/ 1 and that of ${\omega}6/\;{\omega}3$ fatty acids was 17.9/ 1, which was higher than the desirable ratio of $4{\sim}8/\;1$. Average essential amino acid balance of market-Kimbab samples was within the desirable range even though the absolute amount of protein was lower than the recommended level. Contents of antioxidant vitamins (A, C &E) were lower than recommended levels. Two kinds of nutritionally adjusted Kimbab menu were established by self-developed computer program. Some of major changes was adding food ingredients such as tuna fish and perilla leaf cooked with sesame oil and soybean oil to increase ${\omega}3$ series fatty acids. Some fruits and milk were also added to the menu. The adjusted CPF ratios was 63: 15: 22 and the new values for P/ M/ S and ${\omega}6/\;{\omega}3$ fatty acids ratios were 1.0/ 1.2/ 1/0 and 6.1/ 1 respectively. In sensory evaluation of two kinds of adjusted Kimbab, the taste and overall estimation scores were higher than unadjusted Kimbab. The computer program developed in this study might be used as a tool for the evaluation of nutritional balance of other convenience foods and menu planning.

Dried black soybeans were soaked in water at the temperature range of $4^{\circ}C{\sim}100^{\circ}C$ and in salt or sugar solution at $100^{\circ}C$ in order to investigate their effects on the cooking ratio and diffusion property of color pigments. As the temperature increased, the equilibrated absorbance at 490nm of soaking water after 120min was linearly increased. The activation energy for diffusion of color pigments were found to be 4.23 Kcal/mole at the range of $60^{\circ}C{\sim}100^{\circ}C$ and 8.31 kca1/mo1e at $4^{\circ}C{\sim}60^{\circ}C$. The cooking ratio, % cooked beans after heating, of black soybeans were more affected by the salt concentration that of sugar. Both concentrations reduced the cooking ratio as they increased. The sorption isotherm of Kongjaban showed a quite different curves between the storage at $4^{\circ}C$ and $25^{\circ}C$. The sorption and desorption rates during storage could be represented by the equation of $log({\frac{dw}{dt}}{\times}10^3))=alogt+logb$ with a very high correlation.

This study was performed to the possibility of developing anti-aging convenient food that is to Koreans' taste. Editor: this abstract appears to describe a study of public opinion and not related to the development of anti-aging convenient foods. In total, The 150 adults, living in Seoul (Korea), participated in this study in the capacity of subjects. Editor: You really have to mention the age-range of the subjects, as senility is an old age disease. In particular, you talk about the intention of subjects (discussed below) to buy anti-aging food products. This would be directly related to their age, as I assume that older people would be more concerned about senility that relatively younger subjects. They were randomly assigned to 25 groups. In result initial descriptive analysis revealed that, 82 percent of subjects awoke to were aware of senility, and the while 26.7 percent were seriously thought of it concerned. Furthermore, The 58.7 percent said that believed food has the possibility has a role in of controlling senility, and the while 64.0 percent said stated that senility may be controlled by eating constitutional foods. Further comparative analysis of In the case of the group of which members subjects have been who were trying to control senility revealed that their, the reliance on food general and constitutional food was significantly higher than those who have not tried to do so did nothing. The From the 61.3 percent have been of subject who were trying to control senility, from among them, the 74.0 percent and the 22.7 percent were relied on physical taking exercises and anti-aging foods, respectively. Likewise, it was ascertained When asked whether subjects intend to purchase anti-aging convenient food if it was is developed. The 67.3 percent and the 72.7 percent indicated their intentionded to purchase the normal product and constitutional products, respectively. Resultantly, anti-aging convenient food was in demand to some extent. Given that anti-aging products are in high demand, In such a case, senile severity (p<0.05), anti-aging possibility in constitutional foods (p<0.001) and anti-aging action (p<0.001) are regarded as variables in the purchase of the normal products. In the case of relation to constitutional products, anti-aging possibility in constitutional food (p<0.001) and anti-aging action (p<0.001) were regarded as variables.

The purpose of this research was to analyze the effect of consumer innovativeness on the evaluation of online fashion advertisement sustainability and on purchase intentions of advertising products. Online survey have been conducted of 573 people who had experience of online advertisements. The data collected from the surveys were analyzed by the factor analysis, the t-test and the multiple regression analysis. the results are as follows: Firstly, it has been identified that the concept of sustainability of online fashion advertisement consists of four sub-elements of the objectivity of advertisement expressions, the non-harmfulness of advertisement expressions, the protection of personal information, and the non-infringement of web use. Secondly, the group that has a higher consumer innovativeness shows a significantly higher experience of online advertisements as well as more many internet use hours than those who have a lower consumer innovativeness. In addition, comparing with the group that shows lower consumer innovativeness, the group who has higher consumer innovativeness shows a significantly higher recognition of the protection of personal information, the non-infringement of web use and the objectiveness of advertisement expressions among the sub-elements of online fashion advertisement. Lastly, the objectiveness of advertisement expressions and the non-infringement of web use significantly affect the intentions of the group that has high consumer innovativeness to purchase advertised products, and the purchase intentions of those who have low consumer innovativeness are significantly affected by the objectiveness of advertisement expressions and the protection of personal information.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about 'Table etiquette', 'Reasons for eating fruits and vegetables'(78.7%), 'Food waste and environment'(72.3%), 'Healthy snacks'(55.7%), 'Food sanitation'(52.3%), 'Food culture of foreign countries'(48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about 'basic food preperation'(p<0.01). They had learned 'Nutrients for body' and 'Food waste and environment' in school, 'Healthy weight loss', 'Food culture of foreign countries', 'Food circulation' on television, Most content('Table etiquette', 'Simple cooking', 'Food sanitation', 'Eating behaviors for health', 'Reasons for eating fruits and vegetables', 'Healthy snacks') was learned from parents. The practice after nutrition education was higher in 'Table etiquette'(2.14), 'Eating fruits and vegetables'(2.07) than others compared with education experience. The most reason of non-practice on nutrition information was 'Troublesome'. In 'Nutrients for body', a boy answered 'Difficult for practice' 20.0%, a girl answered 'Difficult to understand' 32.6%, showing a significant difference between the gender groups(p<0.001). They remembered the 'Nutrients for body'(49.6%), 'Food sanitation'(44.5%) because of 'important content', 'Basic food preparation'(40.6%), 'Food culture of foreign countries'(36.3%) because of 'interesting content', 'Healthy weight loss'(52.0%), 'Eating behavior for health'(44.5%) and 'Healthy snacks'(33.7%) because of 'need for my health'.

This study was conducted to measure and evaluate the food and nutrient intakes of the people living near the nuclear plant and to investigate the relationship between the household income level and the food and nutrient intake patterns. A total of 552 cases (263 males and 289 females) were surveyed during the period from April 1 to December 21 of 2005. Dietary intake was measured by means of the 24-hour recall method. The data were analyzed using SPSS Windows (ver. 14.0). The household income level of the subjects was classified into two groups : Low income group (LIG; $\leq$2,000,000 won) and high income group (HIG; > 2,000,000). The subjects at large had less energy and nutrient intakes than did the population in town and village who participated in the 2005 National Health and Nutrition Survey. The intake of calcium, zinc, vitamin A, riboflavin, vitamin $B_6$, vitamin C, and folic acid was less than the Estimated Average Requirement in case of $50{\sim}95%$ of the subjects. The LIG consumed less beans, vegetables, fruits, meats, and beverages than did the HIG in male, while the LIG consumed less eggs and beverages than did the HIG in female. The LIG consumed less nutrients than did the HIG in male, except for carbohydrate, while the LIG consumed less nutrients including zinc, vitamin A, riboflavin, vitamin B6, vitamin C, folic acid than did the HIG in female. In addition, the LIG had higher percentage energy consumption from carbohydrate. These results suggest that higher food and nutrient intake is associated with higher income.

In order to reduce the spread of infection due to COVID-19, South Korea has established a four-step social distancing standard and implemented it by changing the steps based on the rate of confirmed cases. The implementation of social distancing brought about a change in the amount of activity of citizens by limiting social contact such as movement and gathering of people. One of the data that can intuitively confirm this is Night Time Light (NTL). NTL is a variable that can measure the size of the national economy measured using lights captured by satellites, and can be used to understand people's social activities during the night. The NTL visible data is obtained via the Visible Infrared Imaging Radiometer Suite (VIIRS) Day-Night Band (DNB) onboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite. 1023 of Suomi data from 1 January 2019 until 26 October 2021 were collected to generate time series of NTL radiance change over Seoul to analyze the correlation with social distancing policy. The results show that implementing the level of social distancing generally decreased the NTL radiance both in spatial disparities and temporal patterns. The higher level of policy, limiting human activities combined with the low number of people who have been vaccinated and the closure of various facilities. Because of social distancing, the differences in human activities affected the nighttime light during the COVID-19 pandemic, especially in Seoul, South Korea. Therefore, this study can be used as a reference for the government in evaluating and improving policies related to efforts reducing the transmission of COVID-19.

This study investigates the effect of Salicornia bigelovii extract on the activities of antioxidant, anti-wrinkle and whitening. Among amino acids, the glutamic acid concentration was the highest with an order of proline > alanine > $\gamma$-amino-n-butyric acid > arginine. The total polyphenol concentration and antioxidant activity were an order of ethyl acetate extract > n-butanol extract > hexane extract > hot water extract > ethanol extract. Especially, when ethylacetate was used as extractant, the total polyphenol concentration and antioxidant activity were 31.6 mg/mL and 82.6%, respectively. The inhibition activity of tyrosinase was increased with the increase concentration of ethylacetate extract. Especially, when the extract concentration was increased from 20 to 100 mg/mL, it was raised from 15.2 to 98.2%. In the case of inhibition activities of elastase, and collagenase, they were also increased with the increase concentration of ethylacetate extract. When the extract concentrations were increased from 20 to 100 ug/mL, they were enhanced from 2.9 to 32.5% and from 3.8 to 29.7%, respectively. The results show that the ethyl acetate extract of Salicornia bigelovii can be applied as sources for functional cosmetics and pharmaceuticals.

The purpose of this study was to verify the construct validity of self-evaluated writing scale for students with disabilities who had difficulties in writing. After interpreting the Here's How I Write scale developed by Goldstand et al. (2013), we administered Delphi survey to 40 special education professionals, calculated the content validity ratio and decided the final scale of 21 questions applicable to Korea. Additionally, we carried out the scale to 350 disabled and normal students for testing construct validity. The main results are as follows: For both students with disabilities and without disabilities, the overall internal consistency of scale are higher than .89 and the internal consistency of factors of scale are higher than .66. The confirmative factor analysis using AMOS 21.0 and SPSS 21.0 to verify construct validity showed fit index at relatively satisfactory level for students with disabilities and without disabilities. Furthermore, while there were relatively strong convergent validity and discriminant validity in the sub-factors of scale for students without disabilities, the level of convergent validity and discriminant validity were relatively lower for students with disabilities.

This study was performed to compare the dietary intake and food sources of zinc (Zn), using a database of Zn composition developed in this study, between elementary schoolchildren in a remote rural area (RA, n=58, $9.9{\pm}1.7\;yrs$) and those in an urban area (UA, n=60, $9.4{\pm}1.8\;yrs$) in Chungnam province in Korea. A dietary survey for three days by food record method was performed. All kinds of foods (n=273) consumed by subjects were collected by aliquot sampling method, and the Zn content of these foods were analyzed by wet technique. The results showed that the daily mean intakes of energy, calcium, iron, and vitamin C from diet in the RA were in the range of 49-88% of the Korean DRI (KDRI), while those in the UA were similar to or greater than the KDRI, except for calcium and iron. The daily mean intake of Zn from the RA diet was $7.0{\pm}0.5\;mg/d$ ($114.1{\pm}8.4%$ of the KDRI), and $16.0{\pm}1.0\;mg/d$ ($258.3{\pm}16.3%$ of the KDRI) in that of the UA (p<0.001). The percentage of dietary intake of Zn less than 2/3 of the KDRI was 19.0% in the RA, in comparison to 1.7% in the UA. Those in the RA consumed Zn from plant foods more often than did those in the UA (p<0.001). Beef rib stew was the food source with highest Zn amount for the total subjects, followed by beef rib meat, roasted; and beef soup w/seasoned red pepper sauce. These results showed that some children in the RA had poor Zn nutrition based upon low intakes and poor food sources of Zn, while overall, children in the UA had good Zn nutrition. Therefore, those in RAs should have their Zn nutrition improved through government policy and nutrition education.
