  • Habitat environment and feeding habitat of Iksookimia koreensis and Cobitis lutheri were investigated in the Mangyeong River, Jeollabuk-do, Korea from 2005 to 2006. They together inhabit the upper and middle stream, but they showed differences in their microhabitat. I. koreensis inhabited the stony zones of relatively rapid waters with a water depth of 30~60 cm, whereas C. lutheri lived in the sandy zones of relatively slow waters with a depth of 30~100 cm. The two species were active during daylight hours from March to October but hibernated in the winter season. During hibernation I. koreensis still lived in the gravel and stone and C. lutheri burrowed in the sand. I. koreensis ingested mainly chironomid and other aquatic insects, whereas C. lutheri fed mainly on Chironomidae, Copepoda and Branchiopoda. The feeding rate of both species was highest in April and September, but they did not feed in the winter.

  • Diel changes in the feeding habits of Rudarius ercodes were investigated in an eelgrass bed of Jindong Bay, Korea. The main food components for R. ercodes (1.6~ 4.3 cm SL) were gammarid amphipods, eelgrass, polychaetes and urochordates. Most dietary items were inhabitants of an eelgrass bed. Diel variations in diet and feeding activity occurred. The diet of R. ercodes underwent changes from eelgrass and gammarid amphipods (omnivore) at day to mainly gammarid amphipods, polychaetes, and urochordates (carnivore) at night. Rudarius ercodes probably took detached eelgrass leaves and grazed live eelgrass during day, whereas feeding on gammarid amphipods, polychaetes, urochordates, and bivalves were facilitated by nocturnal movement and activity of these prey during night. The feeding activity of R. ercodes was also correlated with periods of high tides.

  • The purpose of this study was to identify the factors that related to obesity among 6th grade elementary school girls. The study subjects were 337 girls residing in Seoul. Not only variables of nutritional environment such as eating habits, health related behavioral variables, nutritional feeding methods during infancy, and genetic factors but also sexual maturity had been included as a obesity related factors. Association between obesity and related variables were analyzed by $x^2$(Chi-square) test. The obesity prevalence of the study subjects were 16% based on Röhrer Index(RI). Fifty-three percent of the study subjects experienced menarche at the time of data collection. Result of analysis showed that not only the nutritional enviromental variables such as eating habits, specific food preferences, and habit of exercise but also genetic factors did not show any statistically significant association with obesity. Above finding may imply that more variables other than the variables included in this study might have influenced on the obesity of the children. However sexual maturity in term of breast development showed significant association with obesity.

  • This paper approaches Sir Thomas More, Coriolanus, Pericles in terms of the relationship of food to national identity. These three plays examine ways in which food is essential to what constitutes English national identity, and food shortages give rise to riots thereby throwing everyday life into disorder. In Sir Thomas More food shortages are caused by foreign foodstuff and foreign habits of consumption. Rioting Londoners fear that the European foreigners' strange dietary habits would do harm on English food, the English body and English economy. In Coriolanus starvation is the primary trigger for the enmity between the senators and citizens. Menenius employs the fable of the belly to quell the hungry citizens' anger and to emphasize the senators' role as a store of nutrition to feed the body, that is, the citizens. Coriolanus' contempt for the body's need comes to a devastating end. In Pericles the famine is brought about by the gluttonous consumption of specific foods. The problem of greedy consumption becomes that of living in the cannibalistic situation where mothers are willing to eat their children and married couples one another. Pericles feeds the hungry people with bread, and is also saved from starvation by the fishermen after shipwreck. In this way the three plays provide the examples of Shakespeare's notion on healthy food and feeding.

  • Purpose: This study targeted female university students in their 20s and created an antioxidant improvement program with a health contract, one of the behavioral modification therapies, based on King's (1981) 'goal attainment theory.' The aim of this study is to investigate the effects of physiological indicators, eating habits, dietary attitudes, and health behaviors by conducting a walking exercise and anti-oxidation diet program with reinforcement therapy. Methods: This study had a nonequivalent control group pretestposttest design. There were a total of 50 participants, with 25 participants in the experimental group and 25 participants in the control group and the study period was 10 weeks. The antioxidant improvement program consisted of walking and antioxidant diet education with health contracts. Data analysis was statistically processed using the SPSS/WIN 24.0 program. Results: The program showed a high achievement rate by providing continuous motivation and positive reinforcement during the program, and it affected the eating habits, dietary attitudes, and health behavior. Besides, physiological variables, such as antioxidant indices and body composition showed positive changes. Conclusion: This study, based on the goal attainment theory, confirmed that antioxidant improvement program is an effective nursing intervention for continuous health promotion through interaction and exchange between healthy participants and researchers.

  • The study was designed to observe the effect of complete listing for 10 days on body fatness, serum leptin level and lipid profile in thirty women who were admitted to fasting Clinical Program in Kyung-Hee Oriental Medical Center. Most of the subjects had food habits of over-eating and preferred oily foods which was correlated to the increase of body weight and BMI during realimentation. Average loss of body weight was 7.98kg and waist-hip ratio was significantly decreased during fasting. Body weight showed significant positive correlation with body fat(r=0.8182), lean body mass(r=0.7797) and total body water(r=0.7563). Body fat was gradually reduced after 9 days fasting, but lean body mass was not diminished any more after 7 days luring. Serum leptin level was significantly decreased after luring and re-feeding. The leptin showed significant positive correlation with body weight(r=0.9324), body mass index(r=0.8279) and body fat(r=0.8376). The levels of serum total cholesterol and LDL-C were significantly increased but HDL-C level was significantly decreased after fasting which increased could be harmful for persons with hypercholesterolemia. VLDL-C and triglyceride levels were not significantly decreased after fasting. Serum total free fatty acid level was significantly increased after fasting. These data suggest that the best way of maintaining the reduced body weight was to carry out the modification of food habits and behavior in daily lift. It could not be recommended to repeat often complete luting for reduction of body weight. (Korean J Nutrition 33(1) : 42-48, 2000)

  • The feeding habits of post-larval Yatabe blenny Parablennius yatabei (2.0-9.8 mm SL) were examined on the basis of 158 individuals collected from June to October in the coastal waters of eastern Jinhae Bay, South Korea. Based on the index of relative importance (IRI), post-larval P. yatabei fed 94.4% on copepods and 5.6% on tintinnids. The preference of post-larval P. yatabei for copepods to other prey items results from ontogenetic changes. The dietary percentage of copepods increased as fish size increased and tintinnids became less important. The feeding rate of post-larval P. yatabei was consistent at all times of day.

  • The diet of the walleye pollock Gadus chalcogrammus, was studied by examining the stomach contents of 864 individuals. Using gill nets, samples were collected monthly from January to December 2017 in Jugwang, Sokcho, Yangyang, Uljin, Ganggu, and Gampo, Korea. The specimens ranged in total length (TL) from 16.6 to 75.2 cm. G. chalcogrammus fed mainly on Euphausia pacifica (Euphausiacea) and less on Cephalopoda, Pisces, Mysidacea, and Macrura. The results indicated that G. chalcogrammus is a specialist feeder, feeding mainly Euphausiacea. With growth, however, its diet shifted from Euphausiacea to Cephalopoda, Macrura and Pisces. Smaller individuals (<40.0 cm TL) consumed mainly Euphausiacea. The proportion of Euphausiacea decreased with increasing body size, whereas the consumption of Cephalopoda and Macrura increased gradually.

  • Iksookimia longicorpa was investigated in the upper part of the Seomjin River in Korea from 2003 to 2004. It inhabited pebble and cobble bottoms with water-current velocities of 10~30 cm/sec and depths of 30~100 cm. This species is active during daylight hours from March to October but hibernated in the river bottoms in the winter season. The sex ratio of female to male was 1 : 0.65, and the female was 20~40 mm larger than the male. Female length frequencies in this population indicated that the 65~90 mm group is 1+years old, the 90~110 mm group is 2+ years old, and the 110~130 mm group is 3+ years old. The males developed a secondary sexual character, the lamina circularis at the base of their pectoral fin, after 13~14 months. The spawning season was from early to middle June with water temperatures of $20{\sim}24^{\circ}C$ individuals became sexually mature after the age of 2 years. The average number of eggs in the ovaries was $2,402{\pm}944$. Stomach contents were mainly Chironomidae, Ephemeroptera, Arcellidae and Algae. The feeding rate was highest in April and September; they did not fed in the winter.

  • This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.
