This study examined the effects of a nutrition education program on nutrition-related knowledge, eating habits, and dietary behavior. Subjects were 3rd grade elementary school students in Anyang, Gyeonggi-do. A 5-week nutrition education program was implemented to 28 children and another 26 children were included in the study as a control group. A self-administered questionnaire was used to assess the effects of nutrition education program. Mean nutrition related knowledge score was improved after education (p < 0.001). There was a significant improvement in knowledge of nutrient source (p < 0.05), role of protein (p < 0.05), food tower (p < 0.001), getting information from nutrition labeling (p < 0.05), and proper way of snacking (p < 0.001). Eating habits and self-efficacy also tended to improve by nutrition education, especially eating habit of snack and self-efficacy on balanced diet reached significant improvement (p < 0.05). Food consumption frequency was not changed significantly, only consumption of sea weeds which is considered as a reluctant food among children was increased after education (p < 0.05). In addition, the number of leftover food items and total amount of leftover at school lunch reduced significantly after education when compared with the same 10-day menu prior to education (p < 0.01). This result suggests that unbalanced dietary behavior has been changed with the nutrition education program. In conclusion, the nutrition education program was found to be effective in improving nutrition-related knowledge, eating habits, and dietary behavior.

The effects of a nutritional education program for first grade middle school students were evaluated from August to December, 2006. The study subjects were 82 boys and 90 girls, residing in Gwangju, Korea. To assess the effects of the nutritional education program, pre- and post-questionnaires examining nutritional knowledge, dietary attitudes, and dietary habits were developed. Paired t-test and repeated measures ANOVA were used to evaluate the effects of the nutritional education program. In the general subject, the main after-school activities were studying, watching TV, and using computer (85.5%), and sports (9.3%), suggesting their low physical activity. Parents (46.5%) were indicated as the source of nutritional education rather than teachers (13.4%). Twenty-five percent of girl students had diet experience of skipping meals (54.6%), suggesting the need of proper nutritional education for adolescents' health care. In dietary attitudes, both genders showed some improvement of recognition after education. In the changes in dietary habits, both genders had a significant effect on 'three meals a day, eating breakfast, and regular meal' after education. After education, the rate of having breakfast everyday increased from 52.4% to 65.9% for boys and from 33.3%to 57.8% for girls. In the changes in nutritional knowledge, the appreciation of the importance of school meals increased in both genders from 50.6% to 80.8% after education. The nutritional knowledge, scores of regular eating and well-mannered eating increased in both genders regardless of the students' characteristics. The study results revealed that this education provided an important motivation to improve basic nutritional knowledge and dietary habit. It is recommended to develop systematic and various educational programs and learning materials tailored to subjects before nutritional education.

This study intends to suggest basic data for the activation of rural activities in dietary life education, through a survey of adolescents on rural activities in dietary life education. It was found that 63.2% of subject students had the experience of rural activities; and that as many as 35.2% among the students who experienced rural activities participated in the activities 5 times or more. And the survey showed that rural activities were led most frequently by a teacher in charge (37.9%), and rather rarely by a nutrition teacher (15.4%) or an expert in dietary life education (7.7%). As for food ingredients that adolescents experienced during rural activities, they were composed of easily available good cookers that are common in the Korean diet, and, among them, vegetables were experienced most, followed by cereals and fruits. On the other hand, as for food ingredients preferred by adolescents, it was found that boy students preferred meat, while girl students preferred fruits. And as for improvements in dietary life, it was found that making efforts to have good dietary habits had the highest score, which shows that rural activities contributed to the improvement in adolescents' dietary life. Therefore, given the fact that rural activities go some way towards improving adolescents' dietary life, it is advisable that more opportunities for experiencing rural activities be provided to adolescents in the future so as to help them have good dietary habits.

This study was conducted to investigate the body weight control, attitudes, lifestyles and dietary habits according to the obesity index of elementary school students. This study utilized questionnaires and body composition measurements collected with a bio- electrical impedance analyzer(Inbody 4.0). Specifically, differences between the underweight group, normal group, and overweight group were tested by a $x^2$-test or ANOVA and Duncan's multiple range test. The subjects consisted of 571 elementary school students residing in Chonbuk Province. The average age, height, weight, and BMI of the male subjects was 11.5 years, 150.0 cm, 45.2 kg and $20.0\;kg/m^2$, respectively. The average age, height, weight, and BMI of the female subjects was 11.5 years, 152.2 cm, 46.1 kg and $19.8\;kg/m^2$, respectively. Twenty percent of the subjects were in the underweight group, 52.2% were in the normal weight group, and 27.8% were in the overweight group according to the Korean Pediatrics Society standards. A total of 50.2% of the subjects were dissatisfied with their body weight, while 36.8% of underweight, 42.3% of normal weight, and 81.1% of overweight subjects were dissatisfied with their weight. Fifty two percent of the subjects had attempted to reduce their body weight, including 50% of the normal weight group. The main reason for wanting to reduce body weight was to maintain health. The percentage of subjects who had received body weight control education was 41.3%, but 77.6% of the subjects thought it was necessary. Poor time management, lack of physical activity, portion size of meals, unbalanced diet, frequent consumption of convenience foods, and frequent snacking all affected the obesity index. Overall, the results of this study indicate that it is necessary to develop weight control programs for all elementary school students who are underweight, normal weight, and overweight.

The feeding habits of black scraper, Thamnaconus modestus, were studied using 172 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 16.2 to 39.1 cm in standard length (SL). T. modestus was a omnivore that consumes mainly benthos. Of the benthos species nephtheidae was the most preferred prey. Its diet also includes, algae, thoracica, gastropoda, desmospongia. Small and medium size individuals (<21~33 cm, SL) fed mainly on nephtheidae and algae. Larger individuals (>33 cm, SL) fed mainly on thoracica. The proportion of nephtheidae decreased as body size increased (>33 cm, SL), whereas the consumption of thoracica gradually increased.

The feeding habits of the marbled flounder Pleuronectes yokohamae were studied using 395 specimens collected from January to December, 2010, in the coastal waters off Tongyeong, Korea. The size of P. yokohamae ranged from 10.5 to 38.8 cm in standard length (SL). P. yokohamae is a bottom-feeding carnivore that consumes mainly bivalves, amphipods and polychaetes. Its diet also includes small quantities nemertians, anthozoan, isopods, copepods, tanaidacean, shrimps, crabs and ophiuroids. Our feeding-strategy graphical method reveled that P. yokohamae was a generalized feeder, with a wide niche width. P. yokohamae mainly consumed bivalves, amphipods and polychaetes, and did not show significant ontogenetic changes in feeding habit without size over 22 cm. Prey size did not increase significantly as growing fish size.

Ontogenetic food habits of the four most abundant fish species in seagrass neadows of Redfish Bay, Texas, were examined quantitatively during 1982-1983. The darter goby (Gobionellus bolelsoma) and pinfish (Lagodon rhomboides) were trophic generalists, which used a wide range of food items. The darter goby had relatively diverse, omnivorous diet which included amphipods, copepods, polychaetes, filamentous algae, diatoms, and detritus. This species did not show distinct ontogenetic changes in foodpreferences. Unlike the darter goby, the pinfish showed ontogenetic progression of four feeding stages. An initial feeding stage was a planktivorous stage in which copepods were int major food items, followed by a carnivorous stage in which amphipods became the major food items, an omnivorous stage in which filamentous algae, diatoms, amphipods, and polychaetes were the major food items, and finally a herbivorous stage in which seagrass pieces with attached epiphytes and their debris were the major food items. The code goby (Gobiosoma robustrm) and Gulf pipefish (Syngathus scovelli) appeared to be relatively specialized in food havits as carnivorous. Similar ontogenetic changes in food habits were observed for these two species, i.e.initially, copepods were the major food items, followed by a gradual transition to amphipods with growth.

Background: Cancer is a burden on humanity and ranks as a leading cause of morbidity and mortality in China. Shanxi province has its unique cancer patterns and the burden is increasing. In this study, we aimed to assess the pattern of dietary habits and life-style in Shanxi, a high-risk area for upper gastrointestinal cancers in China and further evaluate the trends in cancer incidence and mortality based on registered data. Materials and Methods: Data on lifestyle, diet, physical activity were obtained from the household health survey at Zhongyang from 2013 to 2015. Cancer diagnoses were reported to Shanxi Center for Disease Control and Prevention (SCDCP). Population-based cancer incidence data and mortality data of 2012 were collected from the SCDCP. All incidence and death rates were expressed per 100,000 populations. Univariate analysis was performed using the Chi-squared test or Fisher's exact test. Results: Overall, deficiencies in fresh fruits and vegetable food, and intake of hot food, salted food, or pickled food are serious problems in Shanxi, especially in rural areas. Upper gastrointestinal cancers were the most commonly diagnosed cancers, and the incidence in rural areas is higher than those in urban areas. Cervical cancer is the most common cancer for females. Moreover, the agespecific incidence exhibited an increased trend before 40 years old. Consistent with the previous literature, our epidemiological investigation results suggest that lifestyle, nutrition deficient, and infections were major risk factors for upper gastrointestinal cancers or cervical cancer in Shanxi. Facing a serious situation, we further explored defensible recommendations for the general public in order to promote changes in environments that support healthful eating and physical activity habits, to reduce cancer risk. Conclusions: Our results present the current cancer trends in Shanxi and its related etiologic risk factors and provide a theoretical basis to guide public health efforts to prevent and control cancers in the province.

The feeding habits of yellowback seabream, $Dentex$ $tumifrons$, were studied using 317 specimens collected in the coastal waters of Busan, from January to December, 2004. The size of the specimens ranged from 10.2 to 27.8 cm in standard length (SL). D. tumifrons had turned out a carnivore and opportunistic predator that consumed mainly shrimps. Fishes were next important prey items. Its diet also included anomurans, amphipods, crabs, echinodermata and cephalopods. Polychaetes, stomatopods, bivalves, ostracods, mysids and so on were minor preys. The individuals of smallest size class (10~13 cm SL) fed mainly on shrimps. In the next size class (13~16 cm SL), the proportion of shrimps decreased, whereas the consumption of anomurans, echinodermata and crabs increased. The proportion of these prey items decreased as body size increased, whereas the consumption of fishes gradually increased. Fishes accounted for almost stomach contents of larger individuals (more than 25 cm SL).

The feeding habits of john dory, $Zeus$ $faber$, were studied using 462 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 7.8 to 40.2cm in standard length (SL). $Z.$ $faber$ was a piscivore that consumes mainly teleosts such as $Trichiurus$ $lepturus$, $Scomber$ $japonicus$, $Callanthias$ $japonicus$ and $Trachurus$ $japonicus$. Of the fish species $T.$ $lepturus$ was the most preferred prey. Its diet also includes cephalopods, shrimps and euphausia. Smaller individuals (<15 cm SL) fed mainly on fishes and cephalopods. The proportion of cephalopods decreased as body size increased, whereas the consumption of fishes gradually increased. Fishes accounted for almost stomach contents of larger individuals (more than 15 cm SL).
