Objects : The purpose of this case study is to report the effect of Su-Gi therapy with Oriental medical treatments on systemic psoriasis. Methods : The subject is a patient with systemic psoriasis. This patient was treated with Oriental medical treatments and Su-Gi therapy. The improvement of the skin condition is observed by Psoriasis Area and Severity Index (PASI) score. Results : After the treatment, the symptoms of psoriasis were relieved. PASI score of this patient went down from 39.6 to 12.5. Conclusions : This study showed that Su-Gi therapy added with Oriental medical treatment can be an effective choice for systemic psoriasis.

Nanomanipulators installed in focused ion beam (FIB), which is used in the lift-out of lamella when preparing transmission electron microscopy specimens, have recently been employed for electrical resistance measurements, tensile and compression tests, and in situ reactions. During the pick-up process of a single nanowire (NW), there are crucial problems such as Pt, C and Ga contaminations, damage by ion beam, and adhesion force by electrostatic attraction and residual solvent. On the other hand, many empirical techniques should be considered for successful pick-up process, because NWs have the diverse size, shape, and angle on the growth substrate. The most important one in the in-situ precedence, therefore, is to select the optimum pick-up process of a single NW. Here we provide the advanced methodologies when manipulating NWs for in-situ mechanical and electrical measurements in FIB.

Here, we introduce a means of utilizing waste oyster shells which were obtained from temporary storage near coastal workplaces as $CO_2$ adsorbents. The calcined CaO can be easily dissociated to $Ca^{2+}$ cation and $CO_3{^{2-}}$ anion by hydrolysis and gas-liquid carbonation reaction and converted to precipitated calcium carbonate (PCC) in algae-containing water. The calcium hydroxide and carbonation combination in algae-containing water significantly contributed to improving water quality which is very dependent on the addition amount of calcined powders.

The purpose of this study was to explore the influence of marital satisfaction and depression of adoptive mother on the problem behaviors of adopted children and the mediating effects of parenting competency between them. Contextual variables such as family background and adoption-related characteristics were also included as control variables. The results of multiple regression analysis showed marital satisfaction had significant influence on the problem behavior of adopted child through flexibility of parenting competency, while depression was not significantly related to parenting competency of adoptive mother. Yet, maternal depression had direct influence on the problem behavior of adopted child. Based on the limitations of the study, suggestions for further study were made.

According to recent studies, Bayesian information criteria(BIC) is proposed to determine the structural dimension of the central subspace through sliced inverse regression(SIR) with high-dimensional predictors. The BIC may be useful in K-means clustering inverse regression(KIR) with high-dimensional predictors. However, the direct application of the BIC to KIR may be problematic, because the slicing scheme in SIR is not the same as that of KIR. In this paper, we present empirical penalty term studies of BIC in KIR to identify the most appropriate one. Numerical studies and real data analysis are presented.

병렬처리를 이용한 GPU(그래픽 프로세싱 유닛)의 연산 능력이 날이 갈수록 고속화됨에 따라 GPU에 대한 관심이 높아지고 있다. GPU는 다중 쓰레드 처리가 가능하도록 CPU보다 수십 배 많은 멀티코어로 구성되어 있으며 이 각각의 코어는 맹렬 프로그래밍이 가능하도록 처리 결과를 공유할 수 있다. 최근 해외에서 이러한 GPU의 연산 능력을 이용한 해쉬인증 공격의 효과가 다수 입증되었으며 패스워드 기반의 인증 방식이 보편화 되어있는 국내에서도 GPU를 이용한 인증 공격이 시도되고 있다. 본 논문에서는 국내 금융권에서 사용되고 있는 공인인증서의 개인키 복호화 과정을 GPU내에서 고속 수행이 가능하도록 개선하고, 이를 바탕으로 패스워드 무차별 대입 공격을 시도하여 공인 인증서에 사용되는 패스워드가 보안의 안전지대만이 아님을 보인다. 또한 날로 발전하는 하드웨어의 연산속도에 맞추어 공인인증서 등에 보편적으로 사용되는 패스워드 정책의 개선 방안을 제시한다.

유한요소해석(Finite Element Analysis)을 통한 풍력발전기 최적설계시, 해석 특성상 발생하는 막대한 소요시간의 개선이 필요하다. 본 논문에서는 연간 에너지 생산량(Annual Energy Production : AEP)의 최대화를 목표로 GA(Genetic Algorithm)와 MADS(Mesh Adaptive Direct Search)를 결합한 혼합 알고리즘을 이용하여 최적설계를 수행하였다. 또한, 혼합 알고리즘과 병렬분산 유전알고리즘을 이용한 최적설계의 해석 소요시간을 비교 및 검토하였다.

Thin film solar cells based on CIGS continue to be a leading candidate for thin film photovoltaic devices due to their appropriate bandgap, long-term stability, and low-cost production. To date, the most successful technique for the deposition of a CIGS absorber layer has been based on the co-evaporation However, the evaporation process is difficult to scale-up for large-area manufacturing the sputtering and Selenizaton process has been a promising method for low-cost and large-scale production of high quality CIGS In this study, we have used Cu and CuIn alloy targets for precursor deposition the precursor deposited by sputtering Cu and CuIn targets and $CuInSe_2$ thin film is manufactured by Selenization process
