The study interviewed 102 North Korean defectors residing in South Korea after completing the Hanawon program through face-to-face interviews. The most celebrated holiday in South Korea was found to be Seollal at 65.7%, followed by Chuseok at 23.2%, Christmas at 7.8%, and Hansik at 1%. With respect to the question of wheather or not North Korea creates a more festive mood compared to South Korea, 33.3% of respondents answered that they felt similar in both countries 2.6% said "yes", they were in a more festive mood in North Korea, whereas 21.6% said "no", and 18.6% said they felt "very different". The most representative traditional food was ranked in the order of rice dishes with kimchi (19.6%), rice cake (11.8%) and boiled rice (8.9%) on National Liberation Day of Korea; rice dishes (17.6%), rice cake (7.8%) and boiled rice (4.9%) on North Korea Constitution Day; and rice cake (57.8%), noodles (9.8%), dumplings (9.8%) and boiled rice (8.8%) on Lunar New Year's Day. In regard to positive recognition about festival foods, "festival food of South Korea has diverse recipes" showed the highest positively in South Korea. The respondents positively recognized that festival foods of North Korea are not sweet, have a unique taste are traditional and have a table setting.

Volatile extracts obtained from traditional Chinese-type soy sauces prepared with soybean (SSSB) and defatted soy meal (SSDSM) by solid phase microextraction (SPME) and direct solvent extraction (DSE) were analyzed by gas chromatography-mass spectrometry (GC-MS). The volatile flavor compounds and relative contents of different chemical classes detected in SSSB and SSDSM were compared for their differences. Results showed that significant differences in both constituents of volatile flavor compounds and relative contents of different chemical classes were observed for both kinds of soy sauces. A total of 152 and 131 compounds were identified in SSSB and SSDSM, respectively, and 102 volatile flavor compounds were common in both kinds of soy sauces. Moreover, relative contents of acids, aldehydes, esters, furan(one)s, miscellaneous compounds, phenols, pyrazines, pyrrol(idinon)es, and sulfur-containing compounds in both kinds of soy sauces were all significantly different.

For the assessment of representative and longitudinal Zn nutriture in South Koreans, Zn, phytate and Ca intakes were determined using four consecutive years of food consumption data taken from Korean National Nutrition Survey Report (KNNSR) every 10 years during 1969-1998. The nutrient intake data are presented for large city and rural areas. Zn intake of South Koreans in both large city and rural areas was low during 1969-1988 having values between 4.5-5.6 mg/d, after then increased to 7.4 (91% Estimated Average Requirements for Koreans, EAR = 8.1 mg/d) and 6.7 mg/d (74% EAR) in 1998 in large city and rural areas, respectively. In 1968, Zn intake was unexpectedly higher in rural areas due to higher grain consumption, but since then until 1988 Zn intake was decreased and increased back in 1998. Food sources for Zn have shifted from plants to a variety of animal products. Phytate intake of South Koreans during 1969-1978 was high mainly due to the consumption of grains and soy products which are major phytate sources, but decreased in 1998. The molar ratios of phytate:Zn and millimmolar ratio of phytate${\times}$Ca:Zn were decreased due to the decreased phytate intake in South Koreans, which implies higher zinc bioavailability. The study results suggest that Zn nutriture has improved by increased dietary Zn intakes and the decreased molar ratio of phytate:Zn in South Koreans in both large city and rural areas.

North Korean defectors who settle in South Korea have experienced severe food shortage and transition of food environment which could affect their health status. However, little is known about their anthropometric measurements and dietary intake after settlement in South Korea. The purpose of this study is to compare anthropometric measurements and dietary intake between North Korean young adults who defected to South Korea and those of South Koreans. We hypothesized that North Korean young adults' physiques and dietary intake would be poorer than that of South Koreans. We compared anthropometric measurements and dietary intake from 3-day food records in a cross-sectional study of 103 North Korean young adult defectors, aged 12 to 24 and 309 South Korean subjects. North Korean subjects were significantly shorter (4.9 to 10.8 cm) and lighter (6.0 to 12.5 kg) than the control group. Body mass index were significantly different between North and South Korean groups only in men. North Korean young adult defectors had lower mean daily intakes of energy and most nutrients and food groups compared to the control group, while North Korean subjects had higher nutrient density diet than that of South Koreans. The proportion of subjects who had dietary intakes of nutrients of less than the Estimated Average Requirement was higher in North Korean subjects than in controls except for in the cases of vitamin A and vitamin C. In conclusion, we recommend providing nutrition support programs for North Korean young adult defectors to secure adequate nutrient intake.

Purpose: Previous studies have reported the difference in nutritional status between South and North Korean infants and young children (IYC). Clear understanding on the nature of such differences is essential for planning food and nutrition policies and programs to prepare for a possible re-unification of the two Koreas in future. This study was undertaken to yield valid statistics comparing the nutritional status between North and South Korean IYC. Methods: Raw data obtained from the 2017 Korean National Growth Chart and the 2013-2017 Korea National Health and Nutrition Examination Survey were analyzed to determine the comparable statistics that include weight for age z-score (WAZ), height for age z-score (HAZ) and weight for height z-score (WHZ), with data reported in the Survey Findings Report of the 2017 DRP Korea Multiple Indicator Cluster Survey. The average weight and height by gender and month were estimated for North Korean IYC and calculated for South Korean IYC. SPSS analysis was applied to evaluate the acquired statistics and compare the nutritional status of South and North Korean IYC. Results: WAZ, HAZ and WHZ of North Korean IYC were observed to be lower than values obtained for South Korean IYC as well as the median values of World Health Organization Child Growth Standards across all ages. Similar patterns were observed for average height and weight. The nutritional status of North Korean IYC revealed a prevalence of highly underweight (9.3%), stunting (19.1%) and wasting (2.5%) values, and was determined to be significantly lower than values obtained for South Korean IYC (0.8%, 1.8%, and 0.7%, respectively). Conclusion: This study has yielded valid statistics that compare the nutritional status of North and South Korean IYC. Results of this study confirm the prevalence of nutritional status difference between South and North Korea.

An individual's food-related personal traits play an important role in influencing personal food choice and habits. According to culture, their influence can manifest differently. To ascertain personal traits about food, FNS (food neophobia scale) and FIS (food involvement scale) were employed in recent studies. This study aimed to understand the food culture and food choices of East-South Asians who live or stay in Korea through comparison of FNS and FIS. Eighty Koreans and 233 East-south Asians (Indonesians, Filipinos, Malaysians, Vietnamese, Thai, Singaporeans, and Bangladeshi) completed a questionnaire to measure FNS (10 questions), FIS (12 questions), and sociodemographic conditions (9 questions). ANOVA was conducted to ascertain FNS and FIS between the groups, and regression analysis was carried out to determine which sociodemographic factors had an effect. The items were analyzed to determine the differences according to gender, age, marital status, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. FNS showed significant differences between the groups with regard to sociodemographic characteristics, except gender, age, and marital status, whereas FIS showed significant differences in gender, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. The results of the regression analysis suggest that nationality strongly affected FNS and FIS, and FIS was also affected by gender.

The goat placenta was fermented by Bacillus subtilis and the optimal fermentation parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (RSM). The effects of fermentation time, initial pH value and glucose content on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity of the goat peptides were well fitted to a quadric equation with high determination coefficients. According to the data analysis of design expert, the strongest DPPH radical scavenging capacity value was obtained with the following conditions: content of glucose was 2.23%, initial pH value was 7.00 and fermentation time was 32.15 h. The DPPH radical scavenging capacity commonly referring antioxidant activity showed a concentration dependency and increased with increasing peptide concentration. The effects of temperature and pH were assessed to determine the stability of antioxidant peptides prepared from goat placenta. Antioxidant peptides showed good stabilities when temperature was lower than $70^{\circ}C$. However, the antioxidant peptides lost antioxidant activities rapidly under alkaline and excessive acid condition. Ultrafiltration technique was performed to separate fermentation broth with different Mw (molecular weight). It was found that peptides in the range of < 3 KDa mainly accounted for the antioxidant activities.

This study analyzed the dietary status of Southeast Asian workers living in South Korea in order to provide basic data to develop a program that allows workers to map desirable eating habits while living in Korea. Questionnaires were completed by 251 Southeast East Asian workers living in South Korea. From our study, we found that respondents ate three meals a day, and Vietnamese had less regular meal times than others. Thai, Cambodian, and Myanmar workers ate snacks several times a day, as they did in their own countries. For adapting Korean food, Vietnamese and Cambodian workers had difficulties due to spicy and salty flavors while Thai and Myanmar works had difficulties due to unfamiliar ingredients and cooking method. Thai workers were the fastest to adapt to Korean food, and the Thai ratio of eating homeland food daily was highest. Male respondents ate more often than women. Workers had access to cooking facilities in their house and usually ate more homeland food than workers that did not have access to cooking facilities. By providing understanding of dietary patterns of Southeast Asian workers, these results can be used as basic data to develop a program for Korean food adaptation.

The present study was conducted to document North Korea's long standing food shortage situation and to evaluate the devastating effects of its recent food crisis on the already poor health and nutritional state of the people in North Korea. We analyzed the mail survey data on food consumption patterns and anthropometry of 109 North Korean defectors, male, aged 20 years and older, who resettled in the South during the period of 1988-1999. The result of our survey data indicated that during 1988-1993 when North Korea's food supply was not yet emerged as a serious problem, food and nutrient intake of North Korean defectors was estimated to be significantly lower that the recommended intake levels for maintenance. Energy and protein intake of subjects who defected further with the recent food crisis. For subjects who defected after 1994, the total and animal food intakes were reduced to 67% and 25%, respectively, of the amounts consumed by those who defected in the period of 1988-1993, and their energy and protein intake was decreased by 27% and 30% to the level of 1,181kcal and 40g. Regardless of the time of defection, the mean height and body weight of defectors was significantly lower than that of South Korean reference men. The prevalence of infectious diseases and malnutrition signs was higher among defectors who resettled in the South after 1994 compared to those who resettled during 1988-1993.
