Recently, the number of subscribers of the webtoons published by some major internet portal companies and others is increasing and their revenues are continually rising. Accordingly, a number of studies are being conducted for this phenomenon. For the uploaders off webtoons, their works are graded and added up for the promotion review but the criteria of such a promotion system usually fall short of readers' expectations. Although most of the subscribes of webtoons are drawn into subscription mainly by the recommendation of people around them, the responses from the new subscribers were often quite different from what the portal companies have anticipated, affecting the rank of the webtoon. Thus, a promotion management system which provides a reliable and clear method of assessment is proposed in this study including the revenue and copyright management scheme for the cartoonists.

Objective : The purpose of this study is as follows. We classify headache into ten kinds as mentioned in DongUiBoGam(東醫寶鑑), and are going to present each acupuncture & moxibustion treatment. Methods : For the purpose of looking for each treatment, we referred to a. large number of literature for headache treatment from ancient to malearn. Results : The ten kinds of headache have each treatment. above all, In treatment of headache due to middle - headache (正頭痛) and megrim(偏頭痛) have pain in the formable of ache part. Therefore, general point such as GV20, GV23, ST8, TE23, Extra Meridian are used in turn, also wind-cold-headache(風寒頭痛) and many kind of headache such as GV16, LI4, GB20 are mainly used much in turn. Especially BL is in common use. Conclusions : We conclude that ten kinds of lumbago have each different acupuncture & moxibustion points and treatment, so if we follow each treatment we might obtain more higher rate the treatment of headache.

Objectives : The purpose of this study is as follows. We classify belly-ache into six kinds as mentioned in DongUiBoGam (東醫寶鑑), and are going to present each acupuncture & moxibustion treatment. Methods : For the purpose of looking for each treatment, we referred to a large number of literature for belly-ache treatment from ancient to malearn. Results : The six kinds of belly-ache have each treatment above all, in treatment of belly-ache due to cold-belly-ache (寒腹痛) and hotbelly-ache (熱腹痛) have pain in the formable of ache part. Therefore, general point such as CVl2, CV8, ST36, Extra Meridian are used in turn. Also bad-blood-belly ache and many kinds of belly-ache such as BL18, BL17, LR2 are mainly used much in turn. Especially CV is in common use. Conclusions : we conclude that six kinds of belly-ache have each different acupuncture & moxibustion points and treatment, so if we follow each treatment we might obtain more higher treatment rate of belly-ache.

점차 늘어나는 클라우드 서비스 이용률과 더불어 보안 위협 또한 증가하고 공격 방법 또한 다양해지고 있다. 하지만 클라우드 환경에서 보안사고가 발생했을 시 대응을 위한 조치나 정책은 여전히 미흡한 실정이다. 보안사고 대응을 위한 디지털 포렌식에 대한 연구를 통해 많은 해결 방법이 제시되고 있으나 클라우드 환경에서는 가상화 기술이 적용되어 있어 기존의 방법으로 증거의 수집 및 보관에 대한 무결성 증명이 까다롭다. 본 논문에서는 클라우드 서비스 이용자가 제공자로부터 서비스를 제공받는 클라우드 환경에서 보안사고 사후 대응을 위해 클라우드 환경에서 포렌식 절차를 수행 시 제안하는 참조모델을 바탕으로 필요한 역할 및 보안 고려사항에 대해 다루고자 한다.

The intercalated compounds of alkylsulfonate into hydrated and dehydrated zinc were synthesized. From the XRD, FT-IR, TGA, elemental analysis data, and the molecular size, the orientation of the intercalated alkylsulfonates was determined. For the hydrated compounds, alkylsulfonates were intercalated into hexaqua zinc layer with the bilayer structure of $32.9^{\circ}$ angle of inclination. For the dehydrated compounds, alkylsulfonates were directly bonded to zinc ion with the bilayer structure of $51.4^{\circ}$ angle of inclination.

We report the laser-induced formation of peanut-shaped gold nanoparticles (Au nanopeanuts) and gold nanowires (AuNWs), and their morphological properties. Pulsed laser irradiation of citrate-capped gold nanoparticles at 532 nm induces fragmentation, spherical growth, the formation of Au nanopeanuts, and the formation of AuNWs, sequentially. High-resolution transmission electron microscopy images reveal that the Au nanopeanuts are formed by instantaneous fusion of spherical nanoparticles in random orientation by laser heating. Furthermore, Au nanopeanuts are bridged in a linear direction to form AuNWs by an amorphous accumulation of gold atoms in the junction. The laser-produced Au nanopeanuts and AuNWs slowly disintegrate, restoring the spherical shape of the original Au nanoparticles when the laser irradiation is stopped. The addition of citrate effectively prevents them from transforming back to the nanospheres.

Ferritic stainless steels for the SOFC interconnect applications are required to possess not only a good oxidation resistance, but also a high electrical conductivity of the oxide scale that forms during exposure at the SOFC operating environment. In order to understand the effects of alloying elements on the oxidation behavior of ferritic stainless steels and on the electrical properties of oxide scales, two kinds of commercial ferritic stainless steels, STS 430 and STS 444, were investigated by performing isothermal oxidations at $800^{\circ}C$ in a wet air containing 3% $H_{2}O$. The results showed that STS 444 was superior to STS 430 in both of the oxidation resistance and the area specific resistance. Although STS 444 contained a less amount of Mn for the $(Mn,Cr)_{3}O_{4}$ spinel formation than STS 430, the minor alloying elements of Al and Mo in STS 444, which were accumulated in the base metal region adjacent the scale, were suggested to reduce the scale growth rate and to enhance the scale adherence to the base metal.

As a part of round robin analysis to develop a finite element elastic-plastic seismic analysis procedure for nuclear safety class 1 components, a series of parametric analyses was carried out on the simulated pressurizer surge line system model to investigate sensitivity of the analysis results to finite element analysis variables. The analysis on the surge line system model considered dynamic effect due to the seismic load corresponding to PGA 0.6 g and elastic-plastic material behavior based on the Chaboche combined hardening model. From the parametric analysis results, it was found that strains such as accumulated equivalent plastic strain and equivalent plastic strain are more sensitive to the analysis variables than von Mises effect stress. The parametric analysis results also identified that finite element density and ovalization option in the elbow elements have more significant effect on the analysis results than the other variables.

Background: The insulin-like growth factor (IGF) system comprises a group of proteins that play key roles in regulating cell growth, differentiation, and apoptosis in a variety of cellular systems. The aim of this study was to investigate the role of insulin-like growth factor binding protein 3 (IGFBP3) in hepatocellular carcinoma. Materials and Methods: Expression of IGF2, IGFBP3, and PTEN was analyzed by qRT-PCR. Lentivirus vectors were used to overexpress IGFBP3 in hepatocellular carcinoma cell (HCC) lines. The effect of IGFBP3 on proliferation was investigated by MTT and colony formation assays. Results: Expression of IGF2, IGFBP3, and PTEN in several HCC cell lines was lower than in normal cell lines. After 5-aza-2'-deoxycytidine/trichostatin A treatment, significant demethylation of the promoter region of IGFBP3 was observed in HCC cells. Overexpression of IGFBP3 induced apoptosis and reduced colony formation in HUH7 cells. Conclusions: Expression of IGF2, IGFBP3, and PTEN in several HCC cell lines was lower than in normal cell lines. After 5-aza-2'-deoxycytidine/trichostatin A treatment, significant demethylation of the promoter region of IGFBP3 was observed in HCC cells. Overexpression of IGFBP3 induced apoptosis and reduced colony formation in HUH7 cells.
