The purpose of this paper, followed by 'Nature$\cdot$Human, and Golden Section I ', is to study aesthetic consciousness, mentality model and body proportion of human, and the golden section applied to architecture and hand axe of stone age. In particular, handaxes of one million years ago have shown that they had critical competency to the basis of art and mathematics in the future. Furthermore, without pen, paper and ruler, the existence of mentality model made fundamental conversion of mathematics possible. Different sizes of handaxes were made by maintaining the equal golden section. This was the first example in relation to the principle mentioned in 'Stoicheia' by Euclid which was published hundred thousands of years later.

The purpose of study was to analyze the process of accepting by BTS fans. The methodology used in this study was qualitative research using grounded theory and the results of the study follow. As a result of open coding, 47 concepts, 23 subcategories, and 14 categories were derived. In the axis coding stage, the casual conditions were "Recognition of BTS image," "Fascinated by BTS image," "Simple consumption of BTS image," and "Arising and expansion of curiosity about BTS image." The contextual conditions were "Accessibility of BTS image" and "Abundance of BTS image searching paths." The central phenomenon appeared to be "Immersing and studying BTS image." The arbitration conditions were "Capabilities required to reproduce BTS image" and "Motivation for contributing BTS image." The actions/interactions were "Presenting BTS image," "Contribution to the spread of BTS image," and "Involved in forming new BTS image." The result was "Emergence and expansion of new BTS image meaning" and "Strengthening attachment to BTS." Through process analysis, it was found that acceptance of BTS images consisted of five stages: "Recognition of BTS image," "Becoming curious about BTS image," "Searching BTS image," "Intervention of BTS image." and "Reproduction of BTS image." As a result of deriving the core categories through selective coding, the core category was "Forming a bond while participating in the BTS image."

Transanastomotic pancreatic duct stent placement during reconstruction following pancreaticoduodenectomy is widely performed to prevent postoperative pancreatic fistulas and duct stenosis. However, stent-related complications, such as stent occlusion and migration, may occur. Here, we report a rare case of a migrated pancreatic duct plastic stent. After pylorus-preserving pancreaticoduodenectomy, the stent migrated to the jejunum and served as a nidus of the stent-stone complex, which developed jejunal obstruction. The stent-stone complex was removed by explorative laparotomy.

Anticarcinogen is one of the major strategies for cancer control. It is well established that dietary factors play an important role in modulating the development of certain types of human cancer. We investiagted the anticarcinogenic effects of Sedum sarmentosum Bunge (SS) with Platycodon grandiflorum A. extracts on HepG2, HeLa and MCF-7 cell lines. By the MTT assay, among the five partition layers of methanol extract of SS (SSM), the ethylether partition layer of SS (SSMEE) showed the strongest cytotoxic effects on all cell lines. We also investigated the synergistic effect of the combination of SS and PG extracts on growth inhibition of the HepG2, HeLa and MCF-7 cell lines compared to the effects of five partition layers of SSM. Combination of SS and PG extracts significantly increased cytotoxic effects on all cell lines. Therefore, we were able to conclude that ethylether partition layer, SSMEE might have potentially useful cytotoxic materials on all the human cancer cells which we used. And we could suggest that the combination of SS with PG enhanced the anticarcinogenic effect on HepG2, HeLa and MCF-7 cell lines. We also determined QR activity of partition layers of SSM, among them, SSMEE on HepG2 cells showed the highest QR activity, 3.21 as control value of 1.0.

Analysis of new approaches to achieve naturally good ecological potential of forest road cut-slope by making the best use of advantages of gabion systems with vegetation base materials to prevent slope failure and erosion, in the area with highly erodible soil. Existing gabion systems can be divided into monolithic and modular system and can be divided into ten subtypes according to the purpose of establishment and combination of other measures. As a result on the monitoring of erosion amount from forest road cut-slopes in the test applications, the order of erosion amount from largest to smallest is as follows: the curved road cut-slope site where normal gabion system was established 5,840 $cm^3$; the control site 5,833 $cm^3$; the straight road cut-slope site where normal gabion system was established 5,621 $cm^3$; the curved road cut-slope site where the new gabion system was established 4,298 $cm^3$; and the straight road cut-slope site where the new gabion system 4,117 $cm^3$. Therefore, the result shows that the new gabion system is more effective than the normal gabion system to reduce erosion amount from forest road cut-slopes. During the study period, vegetation coverages of the straight and curved road cut-slope site where the new gabion system was established were about 56(30~85)% and about 45(28~65)%, so average vegetation coverage of the sites where the new gabion systems was established was higher than the sites where the normal gabion systems was established. Therefore, it was concluded that the new gabion system can be more effective for cut-slope revegetation.

The purpose of this study was to evaluate temperature reduction and heat budget of extensive modular green roof planted with Sedum sarmentosum and Zoysia japonica. Plant height and green coverage were measured as plant growth. Temperature, net radiation and evapotranspiration of concrete surface, green roof surface, in-soil and bottom were measured from August 2 to August 3, 2012 (48 hours). On 3 P.M., August 3, 2012, when air temperature was the highest ($34.6^{\circ}C$), concrete surface temperature was highest ($57.5^{\circ}C$), followed by surface temperature of Sedum sarmentosum ($40.1^{\circ}C$) and Zoysia japonica ($38.3^{\circ}C$), which proved temperature reduction effect of green roof. Temperature reduction effect of green roof was also shown inside green roof soil, and bottom of green roof. It was found that Zoysia japonica was more effective in temperature reduction than Sedum sarmentosum. Compared with the case of concrete surface, the highest temperature of green roof surface was observed approximately 2 hours delayed. Plant species, temperature and soil moisture were found to have impact on surface temperature reduction. Plant species, air temperature, soil moisture and green roof surface temperature were found to have impact on temperature reduction in green roof bottom. As results of heat budget analysis, sensible heat was highest on concrete surface and was found to be reduced by green roof. Latent heat flux of Zoysia japonica was higher than that of Sedum sarmentosum, which implied that Zoysia japonica was more effective to improve thermal environment for green roof than Sedum sarmentosum.

Finespotted flounder, used for a representative raw fish in spring, is considered comparatively difficult to breed, which causes small Olive flounder and Stone flounder from China, similar kinds of flounders, to appear on the market for sale under the name of 'Finespotted flounder.' The reason lies under the considerations that small Olive flounder and Stone flounder from China are relatively lower priced and in higher supply and demand, being difficult to distinguish from Finespotted flounder when sliced with bones. Thus, the purpose of our thesis is to distinguish Finespotted flounder from similar kinds of fish analyzing the lipid content in slices of raw fish and SDS-PAGE(sodiumdodecylsullipide-polyacrylamide gel eletrophoresis). Upon comparing the main components between sliced Finespotted flounder and similar kinds of fish, such as small Olive flounder and Stone flounder from China, we found that there are no noticeable differences among them in moisture content, and little, if any noticeable differences, in crude protein and ash content(P>0.05). Based on these analyses, we have conclude that commercial raw fish restaurants sell small Olive flounder and Stone flounder under the name of Finespotted flounder. However, a variety of factors have an effect on our analysis, such as the individual characteristics of fish and a seasonal variation. The aim of our analysis is to enhance more accurate distinction criteria, although some fish kinds can be discerned with our present technique of examining lipid content and SDS-PAGE. Through more sophisticated analyses developed by consistent research, we look forward to attaining more accurate techniques for discerning between Finespotted flounder and different kinds of similar fish.
