This study was conducted to estimate dietary choline intake of Koreans according to gender, age and region by using the data on per capita food intake in 1998 and 2001 and the data on choline contents of foods customarily eaten by Koreans. Sixty-four and 97 kinds of food items were used for the estimation of choline intake in 1998 and 2001, respectively. And these corresponded to approximately $90\%$ of the total amount of food intake and energy intake. Based on these food items and choline content, per capita choline intake of Koreans was estimated to be 623.0 mg and 602.4 mg in 1998 and 2001 respectively , 687.2 mg and 659.1 mg in 1998 and 2001 for male, 560.2 mg and 551.0 mg in 1998 and 2001 for female. While the number of foods considered in estimation was higher in 2001 than 1998, choline intake was lower in 2001. The estimated per capita choline intake of male population was higher than that of female population by 108-127 mg, possibly due to the difference in total amount of food intake. The age group with the highest choline intake was different between 2 time points. Although adolescents of 13- 19 years showed the highest intake (712.0 mg) in 1998, mid-aged adults of 30-49 years showed the highest choline intake (662.2 mg) followed by adolescents (645.7 mg) in 2001. In regional comparison, choline intake of the rural population (588.7 mg and 588.3 mg in 1998 and 2001 respectively) was lower than that of population in small to medium-size cities (625.1 mg and 603.9 mg) or in metropolitan cities (637.7 mg and 602.8 mg). This result revealed that per capita choline intake of the Korean population falls within the adequate range with some differences by age, sex and residing area.

This study was performed by questionnaire to investigate viewpoints regarding menu excavation and development of native local foods of adults in the Gyeongju area, classified by gender and age. The subject population consisted of 253 citizens(108 males and 145 females) living in Gyeongju. The findings are summarized as follows: The residents highly desired the 'enrichment of service and clean hygiene of local food restaurants', 'active marketing', 'necessity of excavation and development at the present time', and 'development with regional unique characteristics' with regard to the development of the local food choices in Gyeongju, whereas they did not particularly desire 'excavation development of cooking that often is served at family event(birth, marriage, death etc..)', nor 'guidance and enlightenment for many citizens'. The most influential obstacle hindering the development of Gyeongju local food was 'administration support deficiency of connection group agency', followed by 'interest deficiency about local food of restaurant business managers and citizens, different taste of each restaurant', and 'tradition cooking itself is insufficient in Gyeongju'. The most reasonable development menu for native local foods of the Gyeongju area was 'mushroom & beef hot pot(beoseothanu-jeongol)', 'glutinous barley bread(chalborippang)', 'mushroom & bulgogi hot pot(beoseot-bulgogi-jeongol)', 'grilled beef(hanu-sutbul-gui)', and 'grilled minced beef ribs(hanu-tteok-galbi)' in that order. On the other hand, the excavation and development validity scores for 'black goat soup(heukyeomso-tang)', 'gulfweed soup(mojaban-guk)', and 'parboiled octopus(muneo-sukhoe)' were very low.

Objectives: This study examines the status of iodine intake and compares the characteristics (region and thyroid disease prevalence) according to the iodine-sourced food intake pattern in Chinese adults. Methods: An online survey was conducted by enrolling 437 Chinese adults aged 18-65 years, living in three regions with different iodine nutritional statuses: Sichuan, Chongqing, and Guangdong. Results: The prevalence of thyroid diseases in Sichuan, Chongqing, and Guangdong were 12.5%, 8.5%, and 2.8%, respectively. Conversely, the proportion of people who received thyroid disease-related examinations was a mere 37.5%. Among the subjects who underwent thyroid examination, the prevalence of thyroid disease in the three regions was 32.2%, 21.8%, and 8.0%, respectively. No differences were obtained in the total iodine intake by region, but the type of iodine source foods differed. Regardless of the region, the highest iodine content was obtained from seaweed. However, the iodine content from iodized salt and other foods differed significantly by region. Factor analysis revealed three food intake patterns according to the iodine food source. The study further determined regional differences and differences in the prevalence of thyroid disease according to food intake patterns. Conclusions: High salt intake can also increase iodine intake, which is thought to have an effect on the occurrence of iodine-excess thyroid disease. Hence, efforts focused on improving salty eating habits need to be implemented.

최근 방사선 조사는 식품의 발아억제, 살충, 살균 및 숙도조절을 위한 화학약품 처리 등의 대체방안 뿐만 아니라 식품의 저장 및 가공기술로서 인정받고 있으며, 우리나라를 비롯한 약 40개국에서 상업적인 조사식품을 생산하고 있어 이에 대한 정확한 정보를 제공하기 위한 신뢰성 있는 검지기술이 요구되고 있다. 방사선 조사식품 검지법 대상 식품 중 건조향신료 19품목에 방사선 조사 최대 허용선량인 10 kGy까지 $^{60}Co$ 감마선을 단계별로 조사하고 이를 광자극발광법(Photostimulated Luminescence, PSL)을 이용하여 검지특성을 확인하였다. PSL 측정 결과, 건조향신료 19품목 중 14품목은 1 kGy 조사된 시료에서, 1 품목은 5 kGy에서 조사시료(positive)의 threshold value인 5000 이상의 photon count/60 sec로 측정되어 방사선 조사여부의 확인이 가능하였다. 하지만 후추류, 육두구, 계피의 경우는 특이적으로 PSL 측정에 낮은 감도를 보이거나 미네랄 함량이 낮아서 최대 허용선량인 10 kGy 조사시료에서조차 방사선 조사여부의 확인이 불가능하였으며, 이 품목의 경우 열발광분석법(Thermoluminescence, TL) 등을 이용한 방사선 조사여부의 판정이 필요하였다. 또한 식물의 잎을 이용하는 향신료는 비조사 시료와 1 kGy 및 10 kGy 조사시료를 혼합하였을 때, 1 kGy 선량으로 조사된 시료가 1% 혼합된 시료에서도 방사선 조사여부의 확인이 가능하였다.

This study used the functions for public benefits as a standard for evaluating Green Tourism. By referring to the existing literature, the "function of building emotion", the "function of providing a natural environment", the "function of preserving traditional cultures", and the "function of maintaining the local community" have been selected as the measuring variables. Detailed sub-variables of each function were prepared to examine and analyze the recognition of these are the part of Green Tourists. The Green Tourists of Yangsuri in Yangpyeong, Sinnonri in Yangpyeong, and Jurokri in Yeoju participated in the survey for which 13 variables were used as measurement. The results are as follows: First, Green Tourists recognize farm villages as places for rest and relaxation and they laid great importance on the function of providing access to the natural environment. Secondly, out of the 13 measurement variables, "beautiful scenery in farm village", "making a contribution to village income", and "trust in agricultural products" greatly influenced the overall evaluation of Green Tourism. Thirdly, regarding the relationship between the functions for public benefits and Green Tourism, it was found that "facilities and activities for experiencing farming", "facilities for rest", and "beautiful scenery in farm villages" are closely related to building the emotion experienced in these villages, and that "cultivating environmentally-friendly agricultural products" and "beautiful scenery in farm village" are closely related to the function of providing access to the natural environment.

The purpose of this study was to develop cultural food contents from local dishes related to the historical and cultural heritage in the representative areas of Gurye and Jinan. The information on 'Story' was collected from each region's representative local native journal, searches of related web-sites, analysis of old literature, and interviews of traditional households. 'Telling', the conveyance, was focused on texts of literature analysis, which were synthesized from historical conditions, regional food materials, cuisine, regional symbolism, etc. The created food contents were displayed with balanced and healthy Korean food dishes after nutritional analysis. In Gurye, the content was extracted from the story of Hwang hyun (黃玹, 1855-1910) - figura of Gurye - and his collection, "Maecheonyarok", and the storytelling native food was prepared. In Jinan, the content was extracted from the text of an anecdote from "filial son Kwang-beom Lee", a local journal. We tried to express Gurye's clean image in connection with the patriot - Hwang hyun (his nick name was Maecheon), in the late period of Chosun through the unprocessed and simple nature of the dining table. As in Jinan's storytelling materials, we tried to express a healthy menu of health food for older people based on the clean nature and documents about the real character's filial behavior. The developed healthy menu and dining table properties in this study have been established in accordance with nutrient intake standards of energy in Korea.

영산강은 남한의 주요 강에 속하며, 유역은 식량생산의 핵심지 중의 하나이다. 영산강유역에는 범람원과 구릉지가 널리 발달되어 있으며, 현재의 영산호 일대에는 간석지도 넓게 분포했었다. 범람원은 '들'로 불리우며, 골짜기가 중은 '물목'의 상류쪽에 넓게 펼쳐진다. 범람원은 조선 발까지는 거의 전부 논으로 재발되었다. 이 농경지를 배경으로 도회지들이 성장했다. 구릉지는 '등', '까끔', '야산' 등으로 불리우며, 나주시와 영암군에 넓게 분포한다. 구릉지의 농경지개발은 1960년대부터 시작되었으며 오늘날에도 진행되고 있다. 많은 개간지의 영농은 외지인들에 의한 임차농의 형태로 영위된다. 간석지 즉 '뻘밭'은 영산강 하류의 남해만에 넓게 펼쳐져 있었으며, 곳곳에 '개옹'으로 불리우던 갯골이 발달했었다. 간석지는 1981년에 영산강하구둑이 준공된 이후 대대적인 간척사업에 의해 농경지로 개발되어 '영산평야'로 바뀌었다. 새로운 평야의 등장으로 모든 취락이 순수 농촌으로 탈바꿈하였다.
