The purpose of this study was to identify the change in the girth of anthropometric variables during menstrual cycle, and to provide basal data for health promotion program development during pre-menstrual phase and menstrual phase. Participants were 10 healthy women university students without menstrual irregularity, subjective premenstrual syndrome, premenstrual dysphoric disorder, dymenorrhea, obstetrician and gynecologic disease. Chest girth(axillary and papillary), waist girth(half point between iliac crest and 12th rib, and navel), and hip girth were repeatedly measured in menstrual phase, follicular phase, luteal phase during single menstrual cycle. As a result, axillary chest girth in menstrual phase was significantly increased than that in luteal phase. Papillary chest girth and waist girth at half point between iliac crest and 12th rib in menstrual phase were significantly increased than those in follicular phase. No significance was shown in chest and waist girth between follicular and luteal phase. No significance was shown in hip girth during menstrual cycle. In conclusion, signicant difference was shown in chest and waist girth during menstrual cycle. And it is suggested that succeeding research should be carried out with reference to body weight, body fat, blood and local hormone concentration during menstrual cycle.

The main difference between mono-volume rendering and multi-volume rendering is data intermixing. In this paper, we first propose a selective rendering method for fast visualizing specific volume according to the surface level and then present data intermixing method for multiple volumes. The selective rendering method is to generate distance transformed volume using a distance transform to determine the minimum distance to the nearest interesting part and then render it. The data intermixing method for multiple volumes is to combine several volumes using intensity weighted intermixing method, opacity weighted intermixing method, opacity weighted intermixing method with depth information and then render it. We show the results of selective rendering of left ventricle and right ventricle generated from EBCT cardiac images and of data intermixing for combining original volume and left ventricular volume or right ventricular volume. Our method offers a visualization technique of specific volume according to the surface level and an acceleration technique using a distance transformed volume and the effective visual output and relation of multiple images using three different intermixing methods in three-dimensional space.

This paper aims to consider the sexuality elements that the audience perceive from athletes on television images and how those elements influence on audience satisfaction. A total of groups were composed of 3 factors, and a group of men, 8 factors. As a result of the analysis, the correlation ratio to sexuality elements was relatively higher. But the correlation to the sexuality elements, the ratio of preference on sports and the audience quantity on sports program was hardly formed. Also, the result of analysis about the influence of these elements on the audience satisfaction of sports program showed that the higher ratio was in order of the audience quantity of sports program, the preference of sports, the sexuality elements, and so on. As a whole, it was shown that, for a group of college students, the athletes' sexual image on TV had only a slight influence on the audience satisfaction with sports program.

PURPOSE : The purpose of this study was to determine the effects of the length of the pectoralis minor on muscle activity of trapezius and pectoralis major in subjects in subjects with shortened pectoralis minor muscle. METHOD : The subjects was participated in 36 with shortened pectoralis minor muscle. All subjects was examined the length test of pectoralis minor muscle. we divided by 3 groups. group I(n=12) was for 4~5cm of length of pectoralis minor muscle, group II(n=12) was for 5~6cm, group III(n=12) was for above 6cm. The EMG activity of upper trapezius, middle trapezius, lower trapezius and pectoralis major muscle activity was measured by surface EMG while elevationg the right arm in sitting postion with head to the neutral, shoulder elevation $135^{\circ}$ with scaption. Data were analyed using one-way ANOVA with a Tukey post hoc test. RESULT : The EMG activity differed significantly among the three groups(p<.05). The group III had significantly greater EMG activity of upper trapezius and pectoralis major muscles than group I and II(p<.05). Also, The group III had significantly smaller EMG activity of lower trapezius muscle than group I and II(p<.05). But, these was no significant difference in the EMG activity of the middle trapezius muscle among the groups (p.05). CONCLUSION : Therefore, the result of this study should be suggested that the shortened pectoralis minor muscle was affected the EMG activity of the upper trapezius, lower trapezius and pectoralis major. Ultimately the length of the pectoralis minor muscle leads to the muscle imbalance in shoulder girdle.

Continuous taxonomic study on shrimps collected from Korean waters revealed that an alpheid shrimp, Alpheus albatrossae occurs in Korean waters. This species belongs to the macrocheles group of the genus Alpheus. This species is distinguished from other known species of the genus Alpheus in Korea by having orbital teeth and palm of large chela with three heavy longitudinal ridges and grooves terminating distally in (1) a heavy tooth above dactylar articulation, (2) the adhesive plaque, and (3) a heavy tooth below dactylar articulation. Korean Alpheidae fauna now consists of 21 species of seven genera.

In order to expand the acceptability of irradiated foods by public, substantial basic data about the change of nutrient contents during irradiation are needed. The nutrient contents and digestibility of macronutrients such as carbohydrates, proteins and lipids in foods are known to be not significantly influenced by irradiation treatment. However, some of the vitamins among micronutrients are susceptible to irradiation to a large extent depending upon the food composition, food process and storage condition. This study was conducted to investigate change of thiamin in chicken breast, and vitamin C in strawberry and mandarine orange after irradiation. The effects of irradiation at frozen or refrigerated state and the effects of cooking such as heating or micron ave on thiamin contents in chicken breast were observed. Irradiation reduced the thiamin content, however, temperature condition during irradiation was much more important factor to the loss of thiamin contents. In strawberry, vitamin C content was significantly affected by original content or the variety rattler than treatments such as irradiation, heating or microwave. These results indicated that the losses of water-soluble vitamins, especially thiamin or vitamin C, are affected by food temperature during irradiation process and variety or composition of foods rallier than irradiation itself, within an acceptable range of irradiation.

This study was conducted to determine the $F_0$-values of a retort machine at different locations and to evaluate the effects of these $F_0$-values on various quality characteristics of retorted Samgyetang samples. Samples were divided into three groups based on $F_0$-values-T1, 10~20; T2, 20~30; T3, >30. Mineral content in Samgyetang broth and breast meat mostly increased with increasing $F_0$-values. In general, the free amino acid values, hardness, and springiness, except for bone springiness, of Samgyetang decreased significantly at higher $F_0$-values. Protein content of meat and broth of the treated samples were significantly lower than that of the control. An increase in the digestion rate of meat and porridge, as well as the turbidity of the broth was observed in most of the treated samples with increasing $F_0$-values. With increasing $F_0$-values, the $L^*$ and $b^*$ values of meat and the $b^*$ values of broth tended to increase, while the $a^*$ value of broth increased significantly. Electronic nose analysis revealed different flavor patterns for samples treated at different $F_0$-values. For sensory traits, samples treated with higher $F_0$-values tended to receive lower evaluations. Particularly, the color and texture of T3 samples were lower than those of T1 and T2 samples. In conclusion, to improve the quality of Samgyetang, the efficiency and optimization of retort machines as well as the standardization of sterilization techniques are needed.

This study investigated the effect of different electrical stunning methods on pH, water holding capacity(WHC), cooking loss(CL), meat color and blood spot rate in broilers. One-hundred and forty broiler chickens were slaughtered by 50, 65 and 90 voltage with the same electrical frequency(255 Hz) and stunning time(5 sec) in commercial abattoir. The ultimate pH of leg muscle and WHC of breast muscle decreased with increasing the stunning voltage. However, there were no significant differences in ultimate pH, WHC and CL of breast muscle, and ultimate pH of leg muscle. Lightness(L*) and yellowness(b*) values of leg muscle stunned with 90V, 255 Hz, 5 sec were higher than those stunned with 50V, 255 Hz for 5 sec(p<0.05). But there were no significant differences in color value on skin, breast and wing muscle. Our experiments showed that change of stunning voltage affected some broiler meat quality parameters. However, further research is necessary to examine the effects of stunning condition on broiler meat quality.
