  • This study examined the quality characteristics of dumpling shells prepared with 0, 2, 4, 6, and 8% mulberry leaf powder. According to the amylograph data, the composite of mulberry leaf powder-wheat flour samples reduced the gelatinization temperatures, viscosities at $95^{\circ}C$, and maximum viscosity with increasing mulberry leaf powder content. The lightness (L) and redness (a) values decreased with increasing mulberry leaf powder content, whereas the yellowness (b) value increased. In addition, the weight, volume, and turbidity increased after cooking. In terms of the textural characteristics, addition of mulberry leaf powder increased the hardness, springiness, cohesiveness, chewiness, and adhesiveness. The DPPH free radical scavenging activity of the dumpling shells increased significantly (p<0.05) with increasing levels of mulberry leaf powder. The taste, chewiness and texture of the dumpling shells prepared with added 4% mulberry leaf powder were preferred. The sensory evaluation showed that the overall preference of the dumpling shell with the addition of 4% mulberry leaf powder was more effective than the control.

  • Purpose: The Purpose of this study was to examine the degree of obesity stress and analyze factors having an effect on obesity stress among college women. Method: The subjects were 347 female students from a university in J City. Data were collected using a self-report questionnaire for general characteristics, health-related characteristics, and current and preferred somatotype. Obesity stress was measured using 10 items developed by Cho (1996) based on Body Attitudes questionnaire (BAQ) of Ben-Tovim and Walker (1991). The survey was conducted from September 4 to September 7, 2007. Data were analyzed by t-test, ANOVA, Scheffe test, Spearman's rank correlation test, and stepwise multiple regression using SPSS 14.0. Results: The average score of obesity stress was $2.78{\pm}0.90$ out of 5.00. Stepwise multiple regression analysis showed that the major factors that affect obesity stress of female college students were perceived body shape, disagreement between current and preferred somatotype, history of weight control, body mass index (BMI), and perceived health status, and these factors explained 38.4% of obesity stress. Conclusion: Subjective judgment in the perception of or preference for body shape was the most important factor affecting obesity stress in female college students. Therefore, a plan is necessary to mitigate obesity stress and evaluate individually subjects who perceive themselves to be fat or want to be thinner than the current somatotype. And consultation and constant management are needed to help the high risk group (experience of weight control, BMI ${\geq}23kg/m^2$, not good health status).

  • We describe here the mass death of predatory carp, Chanodichthys erythropterus, in Korea induced by plerocercoid larvae of Ligula intestinalis as a result of host manipulation. The carcasses of fish with ligulid larvae were first found in the river-edge areas of Chilgok-bo in Nakdong-gang (River), Korea at early February 2016. This ecological phenomena also occurred in the adjacent areas of 3 dams of Nakdong-gang, i.e., Gangjeong-bo, Dalseong-bo, and Hapcheon-Changnyeong-bo. Total 1,173 fish carcasses were collected from the 4 regions. To examine the cause of death, we captured 10 wondering carp in the river-edge areas of Hapcheon-Changnyeong-bo with a landing net. They were 24.0-28.5 cm in length and 147-257 g in weight, and had 2-11 plerocercoid larvae in the abdominal cavity. Their digestive organs were slender and empty, and reproductive organs were not observed at all. The plerocercoid larvae occupied almost all spaces of the abdominal cavity under the air bladders. The proportion of larvae per fish was 14.6-32.1% of body weight. The larvae were ivory-white, 21.5-63.0 cm long, and 6.0-13.8 g in weight. We suggest that the preference for the river-edge in infected fish during winter is a modified behavioral response by host manipulation of the tapeworm larvae. The life cycle of this tapeworm seems to be successfully continued as the infected fish can be easily eaten by avian definitive hosts.

  • The purpose of this study is to compare the self consciousness of one's body cathexis with other people's. The sample subjects were 97 females between 18 and 24 years old. They were measured on November 1999 with the anthropometric measuring, and their front and side photographs were taken. First, we investigated the size recognition of 5 body parts and ready-made clothing, the consciousness of the size of 5 body parts and body proportion for subjects. Second, we organized panel group consisted of 30 females in twenties majoring the Clothing & Textiles. The consciousness of panel group to the subject's body proportion was investigated by using the front and side photographs of subjects, and was compared with self consciousness of subjects. Data were analyzed by frequency analysis and correlation analysis. Most of subjects recognized their status, bustgirth and waistgirth larger than their real size, but they recognized their hipgirth smaller than their real size and their weight similar to their real weight. And subjects were conscious of their status and bustgirth small, their weight, waistgith and hipgirth proper or a little big, and their body proportion normal or a little unbalanced. The self consciousness of one's body cathexis was related to heights of each part especially, and subjects had a tendency to appreciate their body proportion positively if they recognized themselves tall and thin. Upon comparison of the consciousness of subject's body between subjects themselves and panel group, the appreciation of panel group was better than those of subjects themselves. And we also certified the difference of consciousness of one's body cathexis between oneself and other people. The consciousness of other people was related to the size of each body part, but the self consciousness was predicted that it was more related to the psychological factor including satisfaction or preference.

  • The use of clothes dryers is increasing in Korea and throughout Asia, because of preference for the drum type washer dryer. Clothes dryers consume more energy than almost any other home appliance. This paper suggests efficient ways for drying laundry with condensing clothes drier. We dried cotton fabrics with the condensing clothes dryers and observed the energy input, temperature and RH of the dryer during the drying process. In the early stages of drying process, the air temperature inside the clothes dryer decreased and the RH and the drying time increased as the weight of fabrics increased. We found that it was important to consider the total weight of the fabrics that included heat-sensitive fibers. It took more than half the drying time and the energy input for a 2.5 kg load that it did for a 5 kg load. Therefore, drying larger one load was more efficient than divided smaller loads, because increasing the weight of the fabrics reduced the energy input per kg of drying clothes. The lower the initial moisture regains of the fabrics were, the lower the energy input and the drying time were. The energy input for spinning after washing was much less than that for drying in the dryer. Consequently, it is more efficient to reduce the moisture content of the clothes by lengthening the spinning time of the washer to reduce the energy consumption and the drying time. During the drying process opening the door twice for 30 seconds each time lowered the air temperature and the RH of the dryer, but did not affect the moisture regain of the fabrics, the drying time, and the energy input.

  • This study was designed to investigate factors related to recovery from cerebrovascular accidents(CVA). Medical charts of 100 CVA patients(40 males and 60 females) who had been treated at Bul-Guang hospital in Teagu from June to December 1994 were reviewed to assess their recovery from CVA. Not only types of CVA, blood pressure and serum cholesterol and triglyceride were factors affecting recovery from CVA, but also smoking and drinking status and food preference seemed to be important factors. The percentages of recovered patients were higher in the order of cerebral thrombosis(83.3$\%$), subarachnoid hemorrhage(57.1$\%$), cerebral embolism(50.0$\%$), and cerebral hemorrhage(26.7$\%$). Recovery rates of patients with serum cholesterol below 200mg/dl, 200-239mg/dl, over 240mg/dl were 81.8$\%$, 66.6$\%$, and 16.6$\%$ respectively. Recovery rates of patients with serum triglyceride below 160mg/dl, 160-209mg/dl, and oover 210mg/dl were 84.6%, 72.8$\%$, and 35.7$\%$ respectively. Patients with standard weight recovered better than those with overweight or obesity. Recovery rates of underweight, standard weight, overweight and obesity patients were 73.3$\%$, 85.7$\%$, 45.8$\%$, and 31.6$\%$ respectively. Smoking and drinking seemed to be important factors which inhibited recovery from CVA. Patients preferring spiced foods were recovered better than those preferring salty or pungent foods.
