We survey recognition of nutrition labeling on the processed foods for the college students with distinction of sex and their major. The frequency of purchase that processed food is over the 3-5 times in a week. The man students preferred to have Ramyon, milk and milk products and the woman students' ingested snacks, soft drinks and sugar snacks. For another, the food major students like to have juice, soft drink, milk and milk products. Then again, the non-food major students ingested Ramyon, snacks and sugar snacks. The woman students and food major students show higher recognition of nutrition labeling and confirmation of it. The man student replied reason why to confirm nutrition labeling is to keep their health. But the woman students show interest to confirm nutrition content. The food major students confirm the nutrition labeling to determine the nutrition labels. The non-food major students did not confirm the nutrition labeling because they think it is an involved style. For knowledge of nutrition contents, the woman student and the student majoring food are well informed. But, all of the student show poor knowledge for staple foods, nutrient function and vitamin. As the research results, we suggest that the educated the student nutrition knowledge for nutrition labeling on the products. It helps to improve their dietary life and eating habits. And they can avoid buying of the processed foods by habit without confirmation of the nutrition.

This study was conducted to investigate the differences in daily nutrient intakes, dietary habits and nutrition knowledge between male and female college students. Male undergraduate students 004 subjects) and female undergraduate students (229 subjects) , enrolled at H University in Daejeon, were recruited for this study. The mean age of the subjects was 22.9 year in male and 20.4 year in female students. Daily intakes of energy and nutrients were calculated from the records of one day of dietary food intakes by 24-hour recall method, and general information, dietary habits and attitudes, food intake frequency and food preferences and knowledge for food and nutrition were surveyed through a questionnaire. About $70.1\%$ of male and $66.1\%$ of female students were in the normal range of BMI (18.5 - 23), and $25.2\%$ of male students were over-weighted in contrast to $27.7\%$ of female students were underweight. Males and females were taking $77.2\%$ and $77.9\%$ of RDA for energy, respectively, and $54.8\%$ of male and $48.0\%$ of female students were taking energy under $75\%$ of RDA. Many of them showed deficient intakes of calcium, iron, vitamin A and riboflavin. Average of MAR was 0.75 in male and 0.72 in female students. NAR for calcium, iron, vitamin A and riboflavin in male students were 0.55, 0.69,0.75 and 0.61, respectively, compared to 0.53, 0.51, 0.70 and 0.67 in female students. The nutrients, which have INQ less than 1, were calcium and riboflavin in male, compared to calcium, iron, and riboflavin in female students. There were no gender differences in meal regularity and meal skipping rates, but female students showed higher rates of skipping dinner than males (p < 0.001) About $50.8\%$ of female students were ingesting snacks 1 - 2 time/day, compared to $27.1\%$ of male students. For the food intake frequency, fruit group was significantly eating more for female than male students (p< 0.001) Though female students got higher scores for nutritional knowledge test (p < 0.001) than male students, they did not show better dietary habits or dietary attitudes than male students actually. Therefore, a more active and actual education program accustomed to the different genders and ages with focus on real changing of dietary behaviors needs to be developed and run in schools and local departments.

This study was aimed at comparing the dietary patterns of university female students according to their residence type. As for subjects, one hundred and twenty students of Kongju national university were chosen as a total. They were devided into three groups ; those who live in family home, or university dormitory, or self-boarding house. In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day food records and questionnaire. The result was that mean daily intakes of calcium and iron were lower than RDAs in all groups. According to residence type, subjects of family home and self-boarding seemed to have more serious problem in the nutrients mentioned above considering the proportions of less than 2/3 of RDAs. Especially, iron status was poorer than any other nutrients in the aspects of this proportion and food source. Iron was taken largely from vegetable foods which were recognized as a source of low bioavailability of iron. The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 22, 29, 30 and 19. Thus, it proved that breakfast tended to be more negligent than any other meals, and that snack was an important means to give nutrients for subjects. This meal pattern might be one of the factor for the decrease of the dietary quality. Processed foods were founded to be an important source for providing nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients intake were 30.6, 29.5 and 46.2. However, other nutrient intakes from processed foods such as vitamin and mineral were small. And processed foods which give nutrients were mainly cereal products like ra myon, bread, and milk and milk products. Consequently, processed foods seemed to be selected as a combinient substitute food which supply calorie to fill their hunger. According to the living type, dormitory students had them more frequently than any other groups. Food habit score was within the category of poor or fair. Particularly, the score of self-boarding students was the lowest of groups(p<0.05). The major dietary problems were small or overating, missing meal and irregular eating. The degree of these problems was a little different among groups(P<0.01). Nineteen kinds of food were consumed per day, and family home and self-boarding students had foods less variously than dormitory students(P<0.05). Proportions of skipping breakfast, lunch and dinner were 20.8, 12.5 and 8.3%. Accordingly, breakfast was missed more often than any other meals. And self-boarding students missed breakfast more often than any other groups. As a conclusion, subjects should take more calcium and iron, and eat diverse foods to improve their nutritional status. And it is also necessary that breakfast should be regarded more importantly, and that processed foods should be taken considering nutritional balance. In view of residence type, subjects of family home or self-boarding had more dietary problems than dormitory subjects. Thus, these results suggest that university female students might have low ability of meal management, and dietary patterns were different by their residence type. Therefore, nutrition education for them should be carried out with respect to dewelling environment.

Paragonimus westermani is one of the most popular endemic parasitic diseases in Korea. The nation-wide prevalence survey were carried out by Gobayashi (1921) with sputum examination and by Walton and Chyu (1959) with the intradermal skin test respectively. Recent studies showed the decline of positive rate in intradermal skin test of the local inhabitants and also showed the less distribution of intermediate host. The fact seemed that caused by economic improvement of village people, decrease of intermediate host by increasing use of pesticides, becoming lower water level at streams and rivers and better irrigation and finally by better community health education etc. Gangwha area of Gyeonggi-Do was found out as an endemic area of Paragonimus westermani through some studies in the past, however, in the vicinity area of Gangwha, the study in Kyodong island (myon) was carried out in 1965 by Yun et al. Therefore author carried out the intradermal skin test for 2,380 students of primary, middle and high school in Kyodong island and Samsan island. The results showed as follows : 1) The positive rate of intradermal test for paragonimus westermani infection showed positive in 152 among 1,845 students (8.2%) in Kyodong island, and 21 among 637 students (3.3%) in Samsan island respectively. 2) According to grade levels, 49 among 973 students (5.0%) in primary school, 62 among 962 students (6.4%) in middle school and 53 among 445 students (11.9%) in high school showed positive rate. This showed the higher grade the higher positive rate. 3) Among these total 164 positive cases in the intradermal skin test, only in 3 cases eggs were found in sputum. 4) Finding out the intermediate host, only 28 crayfishes from Kyodong island and 12 from Samsan island were collected and examined for metacercaria infection, however, none of metacercaria was found. 5) As a control group, 2 primary schools from the main island were selected. In these schools from the sixth grade students showed positive rate of 4.8% in Naega primary school and 0% in Hajeom Primary school respectively. Those results showed much decrease than studies carried out in the past. 6) The survey for food habit showed that 15 among 1,274 students (1.2%) had experiences of eating raw intermediate host(crayfish) and 266 among 988 students (27.0%) ate cooked.

In order to investigate the ecological factors affecting milk intake frequency of adolescents, the questionnaire survey was conducted with 929 middle and high school students living in Chungnam urban area through October and November 2004. The subjects consumed milk 8.6$\pm$6.7 times per week, other beverages 4.4$\pm$4.1 times per week and drinking water 3.7$\pm$2.1 cups per day. Of the students 77.3% took balanced meals, 72.8% ate regularly and 36.2% ate adequate amount. About 61% had breakfast everyday and nearly a half students snacked once a day. Nutritional knowledge scores about milk was 7.2$\pm$1.7 and milk attitude scores was 28.1$\pm$6.5. The subjects spent daily 1.8$\pm$1.1, 1.9$\pm$1.1, and 1.0$\pm$0.5 hours for computer use, TV watching and exercise, respectively. Milk intake frequencies were positively correlated with excercise, snack frequency, meal balance and regularity, breakfast frequency, food attitude score and milk preference, while showed negative correlationships with TV watching and computer use. Intake frequency of fruit-tasted and chocolate milk showed inverse correlation with nutritional knowledge. Subjects without either school store or vending machine took milk more frequently than those with one or both did. Of the correlated variables, milk preference was the most important influencing factor to milk intake frequency according to the stepwise linear regression analysis, which presented other 5 important influencing factors as food attitude, school vending facilities, excercise, snacking frequency and watching TV. In conclusion, the improvement of milk preference is the most important and effective way to promote milk consumption in adolescents. The favorite ways of drinking milk, nutritional benefit of milk, healthy beverage and good snacking should be taught in nutrition education. Also physical activities should be recommended to students rather than watching TV, computer use and vending facilities selling soft drinks should be limited to be established inside school.

This study was intended to investigate whether the computer use hours affect physical development, dietary habits, and nutritional status or not. One hundred and ninety elementary school students from Gyeonggi province and Seoul were selected and surveyed during December, 2006. Participants were divided into 2 groups: long-time computer user (${\geq}$ 2 hrs./day) and short-time computer user (<2hrs./day). The survey included the questionnaires and anthropometric measurement. A dietary survey was conducted by using 24-hour recall method. The most of long-time computer user accessed computer more often than those of short-time computer user weekly bases. The purpose of the computer use was for the computer game (p < 0.05). Most participants accessed computer after the school at night and at their home. The longer the computer use, the more the body weight and %RBW (p < 0.05). Dietary habits score of long-time computer user 34.5 points) was lower than that of short-time computer user (38.0 points) (p < 0.001). The long-time computer user consumed more fatty foods, instant foods, and sugary foods. In case of dietary habit changes incurred by computer use, the long-time computer user had inferior dietary habits: skipping meals, meal size, appetite, eating speed, weight, exercise, and sleeping trouble (p < 0.05). The long-time computer user consumed less calories than the short-time computer user (p < 0.05). Also, the long-time computer user tended to have lower intakes of vitamin C, Ca, and dietary fiber without significance. From the findings, the longer use of computer by the elementary school children negatively affects their physical development, dietary habits and nutritional status.

Purpose: Gestational weight gain and prepregnancy body weight are important factors of childbirth outcomes, which further cause obesity, metabolic diseases, or psychological problems later in women's lives. Changes in diet, westernized lifestyle, traditional postpartum care, and childbirth at older age are thought to be threats to proper weight management in Korean women of reproductive age. Public health and antenatal care need to focus on the proper body weight management of women by carefully planning pregnancy to postpartum periods. Purpose: This study explored the body weight changes from pregnancy to postpartum and the related characteristics in women within 12 months after childbirth. Methods: A cross-sectional, retrospective study was conducted with 102 Korean women within 12 months after childbirth. Data were collected using an online survey system, and a structured questionnaire available for electronic self-administration was modified to include demographics, obstetrical history, and body weight at 6 time points. The International Physical Activity Questionnaire and Eating Habit Measurement instruments were also used in data collection. A professional survey agency recruited the participants, and data were automatically saved and then analyzed. Results: The average age of the participants was 33.8 years, 48% were housewives and were well-educated. Seventy-two percent of the participants were primiparas and 82% had breastfed their babies. The body mass index (BMI) ranged from 17.3 to 27.8, indicating that 21.5% of the participants were overweight or obese. The mean gestational weight gain was 11.8 kg, and weight loss was apparent during the first 3 months postpartum. The mean decline in weight was 3.4 kg at one year after childbirth. Women wanted to lose 5.6 kg (range: 3~20 kg), however 44% of them reported that they had not engaged in any weight control efforts. Further, 72% of them reported having engaged in a low level of physical activity. Body weight was not associated with women's characteristics, physical activity score, and diet. Conclusion: Women's awareness of gestational weight gain, lifestyle modification, and the risk of prolonged weight retention should be promoted through the antenatal and women's healthcare systems. As pregnancy and childbirth are critical events that affect women's health, integrative education to ensure healthy transition to life after delivery is required.

The objective was to evaluate the factors influencing on the growth of children aged 3 - 6 years by mini dietary assessment and anthropometric indices in 556 children and by analyzing mineral contents of hair from 273 children by inductively coupled plasma mass spectrometry (ICP-MS). The mean concentration of zinc (Zn) in hair was 68.9 $\pm$ 31.1 ppm and the zinc level of 91 ％ children was less than 60％ of the reference value of 180 ppm. The mean content of lead (Pb) in hair was 1.76 $\pm$ 1.20 ppm, but only 67％ of 273 children was within the reference value of 2 ppm and the lead level of 33％ of children was 2 - 4 times higher than the reference value. The level of Zn was negatively correlated with Pb content (r = -0.305, p 〈 0.01). Hair Zn content, regardless of age, was significantly positively correlated with height (r = 0.214) and body weight (r = 0.159). The height of 95.3％ children was belonged to the normal range of 90 - 109.9％ of standard value and the body weight of 49.8％ children was in the range of 90 - 109.9％ of standard value. However, 8.1 ％ children was overweighted (110 - 119.9％ of standard) and 9.4％ children was obese (120 - 149.9％ of standard) and 0.9％ children was severe obese (〉 150％) which resulted in total 10.3％ obese. Contrary to our expectation, 32.8％ children was underweight (70 - 89.9％ of standard) and 36％ of the underweight children showed the low content of zinc (10 - 49 ppm) in hair. There was no significant correlation between dietary intake of Zn and hair Zn content. Hair Zn content was low even though children consumed greater than 75％ of their requirement for zinc. Regardless of dietary intake of Zn, hair Zn level was rather negatively correlated to the content of Pb in hair. 38.8％ children had an unbalanced diet which resulted in lower intake of calorie, Ca, Zn, vitamin B$_2$ compared with those consuming variety of foods. Therefore, it would be needed that new approach for nutrition education to improve eating habit having the unbalanced diet in preschool children. It might be also suggested to develop new food products to complement the nutrients of Zn, Ca, Fe as snacks or dietary supplement for Korean preschool children.

This study surveyed the ecological characteristics of Squalidus multimacultus at Taehwa River tributary Cheokgwa Stream from January to December 2020. The species inhabited the riverbed that was mostly covered with sand. The water depth was 25-164 cm, and the average was rather deep at 68 cm. The stream velocity was slow at 0.21±0.26 (0.16-0.43) m/sec. The gender ratio of females to males was 1:0.99. The age according to the total length-frequency distribution indicated that the group with less than 50 mm (29.4 - 49 mm) in total length was one year old, the group with 50 - 69 mm was two years old, the group with 70 - 89 mm was three years old, and the group over 90 mm was four years old. The total length of sexually mature fishes was 40 mm for both males and females. The spawning season was from July to August, and the water temperatures was 23.8 - 25.4℃ during the period. The prosperous spawning season was August. The average number of eggs in the ovaries was 1,395 (648 - 2,201) per matured female, and the matured eggs were yellowish and spherical with a mean diameter of 0.67±0.24 (0.62 - 0.83) mm. The live foods were of S. multimacultus attached algae, zooplankton, aquatic insects, and Mollusca. The feeding habits of S. multimacultus were omnivorous, but more than 95% of the stomach content was plant-attached algae. The larger the size of this species, the greater the amount and frequency of eating aquatic insects, which were animal feeds. The population that ate aquatic insects did not eat vegetable food.
