  • The present study was designed to investigate effects of the addition of potato homogenates on fermentation control of salted anchovy. With the addition of $8\%$ (w/w) potato homogenates(P), amino-N content and pH were maintained at lower values in the muscle and juice of salted anchovy during all fermentation periods, And high values in external appearance of the salted and fermented anchovy-body during fermentation period were recorded. Consequently, the suppressing effect on the fermentation of salted anchovy of the addition of $8\%$ (w/w) potato homogenates was proved. As for the factors related to the suppressive effects on fermentation, there was no change in amino-N content, and viable cell counts and pH values were maintained.

  • Objectives : The purpose of this study is to research the Left-Renying and Right-Qikou pulse diagnosis. Methods : We set up locations of the Renying pulse(人迎脈) and the Qikou pulse(氣口脈) on left hand and right hand. On the basis of the medical texts and papers, we researched the relations between the Left-Renying and Right-Qikou pulse diagnosis and the etiological factors(病因), background of appearance of the Left-Renying and Right-Qikou pulse diagnosis, and practical use of medical practitioners of many generations to the Left-Renying and Right-Qikou pulse diagnosis. Results & Conclusions : The Left-Renying and Right-Qikou pulse diagnosis is a method to diagnosis the etiological factors, while it could also be assumed as a tool to apply herbal medicine. This assumption could be made based on the seventh volume of 『Maijing(脈經)』 of Wang Shuhe(王叔和). Chen Wuze(陳無擇) emphasized its function to distinguish etiological factors in 『Sanyinjiyibingzhengfanglun(三因極一病證方論)』, as did Li Dongyuan(李東垣) in 『Neiwaishangbianhuolun(內外傷辨惑論)』. Meanwhile, the connection between Left-Renying and Right-Qikou pulse diagnosis and Zangfu(臟腑) seems to have first been made in 『Maiyu(脈語)』 of Wu Kun(吳昆), while 『Zhenjiazhengyan(診家正眼)』 of Li Zhongzi(李中梓) shows traces of progress since the 『Maiyu』.

  • According to the increase of container flows and the appearance of large-sized container vessels, the container handling equipment in ports is evolving continuously. This research introduces the simulation model for evaluating in detail the mechanical productivity of container cranes. The model considers a single trolley and dual trolleys as the mechanism of a container crane and a single lift, a twin lift, and a tandem lift as the spreader type of it. Additionally, the detail specifications such as the dimension and the speed of a container crane are inputted and the kinematic characteristics of it are simulated. The model also considers the size of a vessel, the storage position of containers in the vessel, and the weight of containers as external physical constraints. Experimental conditions can be configured conveniently because various parameters in the model are separated. Moreover, the model can accommodate flexibly new equipment types and the changes of the existing equipment because it is designed and developed in object-oriented concept.

  • Occurrence and prevalence of Marteilioides chungmueasis have been reported in several waters around Tongyeong but no report has been made for Pukman bay. Therefore, we investigated that the prevalence and infection intensities in Pukman Bay at the inside and the outside areas which are hydrographically divided by tidal current. Furthermore, various environmental parameters were investigated in order to elucidate effective parameter for parasitic infection. Infection rates of Marteilioides chungmuensis in adult oysters were ranged 3.3-20.0% at the inside area during September 2002 through January 2003, and 3.3-30.9% at the outside area during August 2002 through January 2003. External manifestation of infected oyster consisted of abnormal egg masses with nodular appearance in the soft tissue. Histopathological symptoms included massive hemocytic infiltration within or around the follicle wall and atrophic epithelium of digestive diverticula. For the environmental parameters, comparative study made differences between two side of the Bay during the infection period: inside > outside for SS while inside < outside for chlorophyll-a. A positive relationship was observed between chlorophyll-a and infection period, which might indicate the difference in food availability between two areas. The prevalence of ovarian parasite Marteilioides chungmuensis, therefore, was highly associated with food availability. Pearson's correlation analysis was made between environmental parameters and infection prevalence. Significance was observed in water temperature (p < 0.05), suspended solids (p < 0.01) and chlorophyll-a (p < 0.05). A principle component analysis showed that infection of the ovarian parasite, Marteilioides chungmuensis, exhibited effects of seasonality (component I = 55.2%) and chemical/physical environmental factors (component II = 24.4%). These results clearly indicate that the infection of ovarian parasite, M. chungmuensis in the Pacific oyster Crassostrea gigas is closely associated with seasonality and food availability.

  • The color and structure of urban constructions is a factor of urban landscape and shows their characteristics. Hence the modern buildings deal with their materials and external appearance as an important factor, making up the urban image. But it was nearby impossible to evaluate the value of visual landscape with objective measuring method. Most of all, it depends on the subjective estimation of a few talented or high educated experts with a sense of beauty. Such kinds of estimation can in some cases include arbitrary interpretations. In relation to this kind of problems, it is tried here in this study to analyse the human response of brain wave pattern (EEG) with use of SD method, while the tested persons watch the urban landscape scenery constructed in a visual reality. The tested persons were 20 adult male and female with no color blindness and intact cognitive function. Light source with color filter was used for color environment in a dark soundproof chamber. The signal of EEG is analysed digitally and grouped into the ${\alpha}$ and ${\beta}$ waves. The result showed that relative power of ${\alpha}$ wave ratio increased in the natural landscape scenery with blue and green color. From these results it was possible to evaluate the human response, which is affected by urban and natural color and structure stimulation and it might be useful as an indicator of visual cognition amenity toward the design of urban construction environment.

  • This study was conducted to restore our traditional Cheongtaejeon tea and to develop the special products. We inoculated Cheongtaejeon tea with lactobacilli (Lactobacillus plantarum CHO 25) and the mixed microbial strains (L. plantarum CHO 25 + Saccharomyces cerevisiae + Bacillus amyloliquefaciens CHO 104). We also examined the sensuous characteristics and physiological activity of Cheongtaejeon tea which was produced by the inoculation of microbial strains. The external appearance of Cheongtaejeon teas were not significant among the teas which were produced with or without the inoculation of L. plantarum CHO 25 and the mixed microbial strains. The taste of the tea increased most in Cheongtaejeon tea which was produced without the inoculation of microbial strains. The taste and liking of Cheongtaejeon tea which was inoculated with Aspergillus oryzae and Aspergillus niger decreased significantly, and it was not suitable to drink. Total phenolics compound contents, total flavonoid contents and DPPH ($\alpha,\alpha$-diphenyl-$\beta$-picryl-hydrazyl) radical scavenging activity of Cheongtaejeon tea extracts increased much more in the order of that produced with the inoculation of L. plantarum CHO 25, control and that with the mixed microbial strains. However, nitrite radical scavenging activity in 1,000 mg/L Cheongtaejeon tea hot water extracts were in the order of the control (94.4%), the inoculation of L. plantarum CHO 25 (93.6%) and the mixed microbial strains (91.1%). Overall results indicated that the sensuous characteristics increased most in Cheongtaejeon tea which was produced without the inoculation of microbial strains, and those physiological activities in tea with the inoculation of L. plantarum CHO 25.

  • The principal objective of was to assess the effects of herb extracts on the antioxidant activity and quality characteristics of Maejakgwa. The total phenolic and flavonoid contents were found to be the highest by a significant degree in the rosemary, lavender, thyme, lemon balm and olive samples, in order. With regard to electron donating ability, increasing concentrations of added herbs resulted in a more significant rise in the DPPH radical scavenging effect in a range of concentrations of between $100{\sim}1000{\mu}g/m{\ell}$. In particular, the rosemary, lavender, and thyme samples were shown to be lower in antioxidant activity than ascorbic acid, but higher than a-tocopherol, thus the antioxidant activities detected in the rosemary, lavender, and thyme samples were considered to be excellent. With regard to reducing ability, increases in the concentration of added herb extract resulted in significant growth. However, the anti-oxidative activity detected in the rosemary extract was indicated to be superior even to that of $\alpha$-tocopherol when added to concentrations of $500{\sim}1,000{\mu}g/m{\ell}$. In our assessment of external appearance, color, flavor, texture, and overall quality, the highest preference was seen in the control group and in the group with 2% added rosemary extract. The lowest score was earned in the group with a 5% addition of rosemary. The functional ingredients and antioxidant activities of the samples were excellent. Our results appear to indicate that rosemary has some value as a natural antioxidant that can prevent oxidation in food.
