This study was designed to be link in the chain of the investigation on daily life and consciousness of longevous people in Korea, and to investigated the dietary life and its habit of longevous people in the past. The dietary life ana its habit were surveyed on 379 subjects (male 121, female 258) of the aged who were above 80 years of age, from June to November in 1985. 1. Of the taste on staple food of longevous peoples in the past(between 40 and 60 years), 'meal mixed with barley' had the highest figure of 49.9%, followed by 'boiled rice'(47.0%). But it is showed that male preferred 'meal mixed with barley'(56.2%) to 'boiled rice'(41.3%). whereas female slightly preferred 'boiled rice'(49.6%) to 'meal mixed with barley'(46.9%). 2. Of the experience of the food taste of these aged in the past, 'not salted' and 'light' had the highest figures of all 40.6%. It is showed that longevous peoples preferred 'not salted'(40.6%) and 'light'(40.6%) to 'salty'(24.5%) and 'oily'(9.8% ), respectively. 3. By comparison of the intake state of animal protein(meat and fish) of these aged in the past, 'occasionally' was the highest of 55.4%, and decreased in the order of 'almost daily'(31.9%) and 'scarcely'(12.7%). Therefore, it is believed that 87.5% of longevous peoples has taken animal protein 'occasionally' and 'almost daily'. 4. The intakes of major foods above $4{\sim}6$ times a week of these aged in the past and present showed 50.4% and 67.5% for meat, fish, egg and soybean products, 26.6% and 51.5% for milk and its products, 89.9% and 81.0% for vegetables, 58.9% and 64.0% for oiled food, and 57.0% ana 62.934 for seaweeds, respectively.

Objectives: This study examined the consumption of Han-sik and its association with the years of residence in Korea and the socioeconomic status among Filipino immigrant women of the Filipino Women's Diet and Health Study (FiLWHEL). Methods: A total of 474 Filipino women married to Korean men were included in the analysis. Their dietary intake was assessed using a single-day 24-hour recall. The participants provided information on the demographics, socioeconomic, and health-related factors through face-to-face interviews. The generalized linear model and logistic regression model were used to examine the association between the socioeconomic status and consumption of Han-sik. Results: The mean age of the participants was 34.3 years old, and the average duration of residence in Korea was 8.2 years. Among 474 Filipino women, a total of 467 consumed Han-sik, with an average of 6.8 food items per day. The Han-sik foods that the participants consumed most frequently were rice, cabbage kimchi, mixed-grain rice, and fried eggs. The average ratio of Han-sik was 58.57%. The ratio of Han-sik showed no significant associations with the years of residence, years of living together with their husband, education levels, total annual family income, or linguistic competence of Korean. However, the ratio of Han-sik use was associated with cohabitation with parents-in-law; the odds ratio (95% confidence interval) was 2.41 (1.18-4.92, p-trend = 0.002) comparing the fourth quartile with the first quartile of the Han-sik ratio. Conclusions: Filipino immigrant women in the FiLWHEL study consumed a larger number of Han-sik than Philippine foods. In addition, cohabitation with their parents-in-law was associated with the consumption of Han-sik. Further epidemiologic studies will be needed to determine how the diet affects the health and wellbeing of immigrant women in Korea.

BACKGROUND: Pesticide residue analysis is an essential activity in order to establish the food safety of agricultural products. Analytical approaches to the food safety are required to meet internationally the guideline of Codex (Codex Alimentarius Commission, CAC/GL 40). In this study, we developed a liquid chromatograph-tandem mass spectrometer (LC-MS/MS) method to determine the herbicide clopyralid in food matrixes. METHODS AND RESULTS: Clopyralid was extracted with aqueous acetonitrile containing formic acid and the extracts were mixed in a citrate buffer consisted of magnesium sulfate anhydrous, NaCl, sodium citrate dihydrate and disodium hydrogencitrate sesquihydrate followed by centrifugation. The supernatants were filtered through a nylon membrane filter and used for the analysis of clopyralid. The method was validated by accuracy and precision experiments on the samples fortified at 3 different levels of clopyralid. LC-MS/MS in positive mode was employed to quantitatively determine clopyralid in the food samples. Matrix-matched calibration curves were inearranged from 0.001 to 0.25 mg/kg with r2 > 0.994. The limits of detection and quantification were determined to be 0.001 and 0.01 mg/kg, respectively. There covery values of clopyralid for tified at 0.01 mg/kg in the control samples ranged from approximately 82 to 106% with relative standard deviations below 2 0%. CONCLUSION: The method developed in this study meets successfully the Codex guideline for pesticide residue analysis in food samples. This, the method could be applicable to determine pesticides in foods produced domestically and internationally.

Objectives : In order to provide basic data necessary for developing oral health education plane for school continued oral health education by understanding knowledge and activities of oral health. Methods : This study was performed against 324 students at 5th grade of 2 elementary schools in Iksan-si, Jellabuk-do selected through convenience sampling, who were in mixed dentition period that might experience dental caries of permanent tooth. Results : As results, For the knowledge level on oral health by questions, it was found that the case that the elementary school students had correct knowledge on oral health was 'chocolates, snacks, and candies were foods that might often cause dental caries' and 95.8% of the students recognized it well. It was found that for 'must do toothbrushing before going to bed', 'during toothbrushing, I clean my tongue', and 'Proper time necessary for toothbrushing is about 3 minutes', 89.3%, 93.2%, and 89.3% of the students knew the, respectively. When oral health knowledge level by groups was divided into 3 groups and observed, they were classified into Low (0-4 points), Mid (5-7 points), and High (8-10 points). It was found that the knowledge level of each group was High 64.1%, Mid 33.9%, and Low 2.0% and it was identified that the high group took the largest ratio. It was suggested also for oral health knowledge level depending on their father's academic background that there was a statistically significant difference in the group higher than university graduate(p<.05). It was found for oral health knowledge level depending on parents' dental condition that an answer that both parents were good was high and there was a statistically significant difference. But post-analysis resulted that there was no apparent difference among groups. It was found that the ratio of respondents who answered for toothbrushing method 'toothbrush should be moved and rotated downward for the upper teeth and upward for the lower teeth to clean the teeth and gum' were 33.2% of male students and 29.4% of female students and showed statistically significant difference (p<0.05). It was found also that the ratio of respondents who answered to use a toothbrush for about 3 months' were 29.4% of male students and 25.5% of female students and showed statistically significant difference (p<0.05). Conclusions : Oral health program through the elementary school students and their parents for the development of proper oral health care education programs continue to be made should be considered.

For the purpose of obtaining basic data which can be applied to processing of retort pouched shell-fishes, retort pouched seasoned baby clam was prepared. After sand and mud were removed, and then steamed baby clams were shucked. Baby clam meats were seasoned with the mixed seasoning powder containing $3\%$ of sugar, $2.5\%$ of salt, $12\%$ of sorbitol, $0.5\%$ of monosodium glutamate and $10\%$ of smoke flavor, and then dried at $35-40^{\circ}C$ for 3 hours. After dried, the meats were vacuum packed in plastic film bag (polyester/nylon/unoriented polyproylene; $12{\mu}m/15{\mu}m/50{\mu}m,\;15{\times}17cm$), and sterilized for 12 minutes in a hot water circulating sterilzer at $120^{\circ}C$, The factors such as pH, VBN, moisture content water activity, color value (L, a, b), texture, TBA value and viable bacterial count of products were determined during storage at room temperture ($20{\pm}3^{\circ}C$). The results showed that the product could be preserved in a good condition for 120 days at $20{\pm}3^{\circ}C$. Judging from the scores of sensory evaluation on flavor, the product added smoke flavor as seasoning was the most desirable.

Olive flounder Paralichthys olivaceus production has increased gradually in recent years, but prices have fallen. Thus, the development of a variety of processed foods incorporating olive flounder would help to increase the income of fishermen. This study was conducted to investigate the best method for olive flounder ball processing. Clean olive flounder were divided into five portions. Olive flounder meat (100 g with added egg white 39 g) was chopped and then mixed with 10 mL fresh cream and ingredients. The dough was molded into the shape of a ball. The olive flounder balls were then processed by two different methods. In the first method, the flounder ball was boiled in water for 3 min then vacuum-packed in polyethylene film and stored at $-20^{\circ}C$ for 7 days. After 7 days, the ball was thawed and heated in a microwave for 2 min (Sample-1). In the second method, the ball was vacuum-packed in polyethylene film without boiling and then stored at $-20^{\circ}C$ for 7 days before thawing and boiling in water for 3 min (Sample-2). After heating, both types of olive flounder balls were evaluated. Various factors (including the viable bacterial count, chemical composition, pH, hardness, thiobarbituric acid level, salinity, and free amino acid content) were measured, and a sensory evaluation was conducted. Based on the results of the sensory and hardness evaluations, Sample-1 was deemed to be superior to Sample-2.

The natives of the genus Corbicula have shown worldwide dispersion in recent times, which has caused great ecological and economic impacts on the introduced ecosystems. The species reported from the genus have been consumed as food and explored for medicine with pharmacological activity. Consequently, the demand of Corbicula sp. in the South Korean domestic market has increased and so also it's associated import to the country. However, due to the absence of identification keys of imported Corbicula, the market is facing confronting situations. We hypothesized that the mitochondrial Cytochrome Oxidase I gene (CO-I) based molecular profiling could be a necessary technique for identification of Corbicula sp. in the South Korea domestic market. The genetic analysis identified both Corbicula japonica and Corbicula fluminea from the market foods. C. japonica and C. fluminea are inhabitants in Korea, but C. fluminea production has decreased in Seomjingang river basin. Therefore, C. fluminea identified from this study, is expected to be imported from China and would have a mixed sales in Seomjingang river side basin.

Varieties of the cereals produced in the Biblical times and the ways these cereal foods have been grafted into Korean food culture has been pursued, and the regulations of agricultural life and the metaphors or parables of cereals represented throughout the Bible have been studied. The word "grain" appears eight times in the KJV and one hundred seventeen times in the RSV. On the other hand, the word "corn" shows up one hundred and one times in the KJV but not in the RSV at all. Wheat, one of the earliest cultivated and the most important grains for food is mentioned fifty two times in KJV and generally the rich in those days lived on wheat in the parched state or in the form of bread. Barley, one of the staple cereal crops of Palestine is referred to thirty six times in the KJV. It was less expensive than wheat and so was used mainly for the food of such animals as horses, donkeys and cattle, but sometimes it was mixed with flour and used for making bread for men, mostly for Poor men. The spelt (in ASV and RSV) and the rie(in KJV) appearing in Exodus 9:32 is a kind of grain, which is translated into Na-mack (in Hangul Revised Bible ; HRB), Ssal-bori (in Hangul Common Translated Bible : HCB) and Ho-mil (in Hangul King James Bible; HKJB) but which should be put into Spelt-mil in Korean. The lentil appearing in Genesis 25 : 34 is translated into Pat (red-bean) and Bul-kong respectively in HRB and HCB but the same word in the Second Book of Samuel is translated into Pat in both HRB and HCB. HCB translates lentil into Bul-kong in Genesis and into Pat in the Second Book of Samuel (23:11). HCB and HKJB which put lentil into Pat in previous parts translate the word into Nok-tu in the Second Book of Samuel. The word, lentil here should be put into lentil-kong and parched pulse into "Poken-Chong-ja" not into Poken-Nok-tu. Millet which is translated into Cho should be put into Gui-jang. filches should not be classified as a grain or a cereal but as a flavor or a condiment, so the word filches should be put into So-Hoi-hyang or Hoi-hyang. Regulations in reference to agriculture are included in the Bible. That is, it is seen that the Bible regulates the observance of the sabbatical year and feasts, the partition of land, how to sow and so on. It is also observed that grains are used for metaphors or parables: wheat represents the peaceful times and straws are compared to trifles. As seen above, there should be more prudent examinations and standards for the translation of grains into Pat, Pul-kong, Nok-tu, Gui-ree, Ssal-bo-ri and Na-mack.i-ree, Ssal-bo-ri and Na-mack.

The relationship between dietary practices and juvenile delinquency was studied using a dietary survey. Subjects were selected from juvenile delinquents who were under the supervision of the Seoul Probation Office of the Ministry of Justice. The study group consisted of 52 male and 52 female delinquents. As a control group, 104 exemplary high school students were selected in Seoul. A questionnaire was designed to find out the subjects' general characteristics, dietary habits, lifestyle, eating behavior, food frequency, and nutrient intake using the 24-hour recall method. Compared to the exemplary students, the juvenile delinquents were significantly different in education level, family status, monthly allowance, residence status, breast fed, parents' education level, parents' concern. In dietary habits, fifty-eight percent of the juvenile delinquents ate 2 or fewer meals per day, preferred to eat with friends, and liked hot tasting foods. The juvenile delinquents consumed more ion drinks (OR = 9.26 CI: 3.83 -22.37), rameon (OR = 7.67 CI: 3.21 - 18.33), cola (OR = 6.75 CI: 2.91 - 15.69), soft drinks (OR = 6.12 CI: 2.53- 14.81), steamed korean sausage (OR = 5.34 CI:2.31 - 12.32), hamburger (OR = 5.15 CI: 1.91 - 13.87), kimbab (OR = 3.63 CI: 1.76-7.46), ddokbokgi (OR = 3.17 CI: 1.58-6.38), candy (OR = 3.08 CI: 1.41-6.73), white rice (OR = 2.59 CI: 1.19-5.64), hotdog (OR = 2.52 CI: 1.31-4.86), and less rice mixed with grains (OR = 0.02 CI: 0.01-0.05), tangerine (OR = 0.06 CI: 0.02 - 0.20), milk (OR = 0.29 CI: 0.14 - 0.60), roasted fish (OR = 0.32 CI: 0.28-0.99, anchovy (OR = 0.35 CI: 0.17 - 0.72), seaweed (OR = 0.37 CI: 0.16 - 0.83), and tofu (OR = 0.48 CI: 0.23-0.99) than the exemplary students. With respect to the juvenile delinquents, the nutrient intakes lower than 75％ of the Korean RDA were for riboflavin (75.0％) and calcium (47.9％) among the boys, and calcium (46.9％) and iron (60.4％) among the girls. To prevent juvenile delinquency, nutritional education and well-balanced school food service meals should be emphasized so as to improve the management of dietary practices.
