  • The purpose of this study was to investigate the effects of adding various amounts of ingredients on the physicochemical and sensory characteristics of Bokbunja-jelly. The proximate composition of Bokbunja-jelly was 19.0% for the moisture and 0.8% for the crude protein. The Hunter L-values of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose were higher than that of Bokbunja-jelly prepared by adding 20 g RME or 100 g sucrose. The Hunter b-values of Bokbunja-jelly prepared by adding 20 g RME or 120 g sucrose was higher than that of Bokbunja-jelly prepared by adding 10 g RME or 120 g sucrose. The hardness and chewiness were increased with decreasing Rubus coreanus Miquel extracts. According to the results of the sensory evaluation, no significant differences in flavor, sweetness, hardness, elasticity and overall qualities were found. According to the results of physicochemical properties and sensory evaluation, the optimal recipe for preparation of Bokbunja-jelly was determined to be 240 g water, 120 g sugar, 110 g glucose syrup, 4 g agar, 20 g Rubus coreanus Miquel extracts and 0.3 g Rubus coreanus Miquel flavor.

  • We discuss the decomposition problems on circuit graphs and triangular graphs, and show how they can be applied to obtain results on spanning trees or hamiltonian cycles. We also prove that every circuit graph containing no separating 3-cycles can be extended by adding new edges to a triangular graph containing no separating 3-cycles.

  • Existing research on the investment relationship between venture capital and start-up companies has mainly focused on choosing a startup from the perspective of venture capital, an investor. However, as competition among venture capital has increased recently, excellent start-ups with proven technology are choosing venture capital in reversely. This study investigated key elements that affect the selection of the venture capital by a startup. To this end, we looked at which venture capital company was selected as the final investor for startups that have received investment proposals from multiple venture capitals at the same time. Six early start-ups(pre-series A/Series A) and five mid-term (Series B/C) start-ups were interviewed to focus on the influence of the three elements regarding venture capital - 1) venture capital reputation, 2) relationship between cofounders and investors, and 3) value adding service provided by venture capital - on choice. As a result of the research, the investment portfolio among the reputations of venture capital was a very important element in selecting venture capital. However, it has been shown that the age and asset under management of venture capital are not important. Relationships have emerged as a very important element. Finally, as for venture capital's value-adding services, start-ups in this study did not consider it important. In particular, consulting and monitoring by venture capital has been found to be a burdening attribute for startups. This study suggests implications that can increase the probability of successful investment by venture capital in the investment market where investment competition is fierce, and enhance mutual understanding between venture capital and startups.

  • In this study, the effect of Nano silica (SiO2) on the buckling strength of the glass fiber reinforced laminates containing the machining process causes holes were investigated. The tests have been applied on two status milled and non-milled. To promote the mechanical behavior of the fiber-reinforced glass epoxy-based composites, Nano sio2 was added to the matrix to improve and gradation. Nano sio2 is chosen because of flexibility and high mechanical features; the effect of Nanoparticles on surface serenity has been studied. Thus the effect of Nanoparticles on crack growth and machining process and delamination caused by machining has been studied. We can also imply that many machining factors are essential: feed rate, thrust force, and spindle speed. Also, feed rate and spindle speed were studied in constant values, that the thrust forces were studied as the main factor caused residual stress. Moreover, entrance forces were measured by local calibrated load cells on machining devices. The results showed that the buckling load of milled laminates had been increased by about 50% with adding 2 wt% of silica in comparison with the neat damaged laminates while adding more contents caused adverse effects. Also, with a comparison of two milling tools, the cylindrical radius-end tool had less destructive effects on specimens.

  • In order to know the effect on the growth of experimental rats, this, this experimental rats, this experiment was carried out on two groups of rats-a rice-diet animal group and a stock-diet animal group. Results of the growth experiment are shown in the tables 3 and 4, and growth curves are shown in the figures 1 and 2. The growth curves are shown in the figures 3 and 4. Based on the statistical analysis of growth rats, the male group on stock-diet was stimulated significantly in its growth by adding antler. The female group on rice-diet was also significantly stimulated in growth by anter. The other groups are not significant but it seems likely that the growths wers stimulated. As shown in table 7, the numbers of days when the body weight of the animals in each group became two times, three times, three times, and four times are discussed. This method of analysis shows clearly the stimulation of growth by adding antler in each group in both sexes. It can be summarized that the antler stimulates the growth of the experimental rats but it is not discussed in this paper whether this stimulation in the growth might be due to calcium, vitamins and amino acids in antler or to an unknown growth factor.

  • In this study, we examined the effects of background and underline on the readability of displayed text. The background was placed on every other line and the underline was done with every line of the text. The effect of adding color to the background and underline was also of primary concern. Twenty subjects were tested on their reading efficiency (i.e. time-to-read and comprehension) and subjective preference of different text format presented on a LCD. Result showed that for the background condition, the background with green format significantly decreased the time-to-read as compared to the format without any background. The results of ANOVA on comprehension and subjective preference were also consistent with this finding. For the underline condition, otherwise, the underline with yellow format yielded higher speed and better comprehension. The results imply that adding background or underlines with appropriate colors can be an additional and useful way of improving text readability.

  • The purposes of this study were to examine applicability of waste egg shells as conditioning agent, to determine the optimum conditions for improving digested sludge dewaterability and to compare with before and after adding them. It estimated that the optimum conditions were dosage 30 g/L, particle size 10mesh, temp. $30^{\circ}C$, pH 7 and dewatering pressure $2.66{\pm}10^4{\;}N/m^2$. On the basis of induced optimum conditions, if adding waste egg shells in digested sludge, its specific resistance was $1.13{\pm}10^{12}{\;}m/kg$ and was low about 3 times than raw digested sludge $3.5{\pm}10^{12}{\;}m/kg $. Therefore, in view of waste recycling, it seemed that we could utilize waste egg shells as conditioning assent for improving dewaterability of digested sludge.
