  • Juice Valley and Gogu Valley were administered to twelve healthy young volunteers for 4 weeks to study their clinical effects on human intestinal microflora. Changes in fecal microflora, fecal moisture, and fecal pH were observed for Juice Valley intake. Administration of Juice Valley significantly increased numbers of Bifidobacterium and Lactobacillus from 8.69 and 7.02 to 10.89 and 9.02 (Log CFU/g wet feces), respectively, whereas those of Clostridium perfringens and Escherichia coli decreased. Moisture content of feces increased, and fecal pH decreased after 4 weeks of Juice Valley intake, intake of Gogu Valley slightly increased growth responses of Bifidobacterium and Lactobacillus and decreased growth responses of C. perfringens and E. coli. Su-mi potato, as a reference, had no effect on Bifidobacterium and Lactobacillus numbers. This study confirmed Juice Valley has better effects than Gogu Valley and Su-mi, and has important role on growth promotion and inhibition of human intestinal bacteria.

  • This study was carried out to introduce current status to discuss erosion control strategy for the conservation of stream valley ecosystem. To restore stream valley ecosystem, we should establish restoration plans to keep the original shape of stream. It is necessary to use environmentally sound materials with conservation of valley stability. Valley construction for erosion control works should be evaluated continuously based on concepts of conservation and development of stream valley ecology. It is categorized in point of the important of class of stream valley conservation ahead planning and constructure. We suggest that the development of stream valley construction needs to prevent mass movement of soil sediments. In addition, it is established the basal strategy to protect macro and micro aquatic organisms in stream valley ecosystem.

  • Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.

  • The purpose of this study is to clarify the effect of mountain-valley wind on heat island formed in urban area which is located around valley mouth. The meteorological observations were carried out over the Dalbi-valley under a clear summer pressure patterns, and some consideration were tried from the results. In order to make clear the climatological characteristics and air-mass modification process of the mountain-valley wind over the valley, the meteorological observations were done simultaneously at two points. The observational points were located at the breast and valley mouth parts, respectively. The results were as follows: First, it was found that the valley wind was observed through the daytime, and it was replaced by a mountain wind after sunset. Second, the heat budget is also investigated with observation data. The sensible heat flux over the breast of Dalbi-valley reached to about $200 W/m^2$ during daytime, which is a little more than one third of net radiation. On the other hand, the sensible heat flux represented negative values during nighttime. But the sensible heat flux over the valley mouth covered by asphalt showed plus value(about $20{\sim}30 W/m^2$) during the nighttime.

  • Wind tunnel experiments were conducted to investigate the wind characteristics in the mountainous valley terrain with 4 simplified valley models and a 1:500 scale model of an existing valley terrain in the simulated atmospheric neutral boundary layer model. Measurements were focused on the mean wind flow and longitudinal turbulence intensity. The relationship between hillside slopes and the velocity speed-up effect were studied. By comparing the preliminary results obtained from the simplified valley model tests and the existing terrain model test, some fundamental information was obtained. The measured results indicate that it is inappropriate to describe the mean wind velocity profiles by a power law using the same roughness exponent along the span wise direction in the mountainous valley terrain. The speed-up effect and the significant change in wind direction of the mean flow were observed, which provide the information necessary for determining the design wind speed such as for a long-span bridge across the valley. The longitudinal turbulence intensity near the ground level is reduced due to the speed-up effect of the valley terrain. However, the local topographic features of a more complicated valley terrain may cause significant perturbation to the general wind field characteristics in the valley.

  • The Uncanny Valley phenomenon has already been deemed as theoretical, and the characteristics of game character expression elements for the Uncanny Valley phenomenon were recognized through case analysis as well. By theoretical consideration and case studies, it was found out that the influential elements of the Uncanny Valley phenomenon can be classified as two primary factors: character surface treatment and facial expression animation. The prepared experimental materials and adjectives were measured to be Five-Point Likert Scale. The measured results were evaluated for both influence and comparative analysis through essential statistical analysis and Repeated Measuring ANOVA in SPSS. The conclusions which were drawn from this research are as follows: The surface treatment of characters did not substantially affect the Uncanny Valley phenomenon. Instead, character's expression animation had a significant impact on the Uncanny Valley phenomenon, which also led to another conclusion that the facial expression animation had an overall deeper impact on Uncanny Valley phenomenon compared with character's surface treatment. It was the unnatural facial expression animation that controlled all of the independent variables and also caused the Uncanny Valley phenomenon. In order for game characters to evade the Uncanny Valley phenomenon and enhance game immersion, the facial expression animation of the character must be done spontaneously.

  • Comparisons of the physico-chemical characteristics between white Atlantic potatoes and violet Bora Valley potatoes were performed. According to the results, Bora Valley had 7% higher moisture content than Atlantic, but there were no differences in crude fat and crude ash contents. Bora Valley, however, had about 3% less crude protein content than Atlantic. In a vitamin C analysis by HPLC, the Atlantic and Bora Valley potatoes contained 14% and 39% vitamin C, respectively, indicating that Bora Valley contained about twice as much of the vitamin as Atlantic. In a vitamin C analysis by HPLC, the Atlantic and Bora Valley potatoes contained 14% and 39% vitamin C, respectively, The dietary fiber content of Bora Valley was 3.12 g per 100 g higher than that of the Atlantic variety. While Atlantic contained neither glucose nor fructose, both sugars were measured in the Bora Valley potatoes, and there was no difference in sucrose content between the cultivar.
