  • A decrease in the fertility rate leads to a reduction of troops, so the need to efficiently operate the troops is growing. Therefore, it is necessary to develop a system for estimating warship manpower. In this study, system development was performed according to the CBD methodology. The user requirements were defined and the system function that satisfies the requirements was derived. And through the development process, the CBD methodology and the systems engineering process were compared. As a result, similarities were confirmed in the analysis and concept design stages, so the possibility of merging the two processes was suggested.

  • Objectives: This study was to discuss the research trend of dementia treatment using cannabis for the purpose of providing the basis of cannabis use for medical purposes in the future. Methods: This study searched publications, which were registered to databases or published by Aug 22, 2019, and targeted the full-text or abstracts of these publications. We selected the final nine studies met all selection criteria. Results: These results implied that the CBD components of cannabis might be useful to treat and prevent AD because CBD components could suppress the main causal factors of AD. Moreover, it was suggested that using CBD and THC together could be more useful than using CBD or THC alone. Conclusion: We hope that there will be a solid foundation to use cannabis for medical use by continuously evaluating the possibility of using cannabis for clinical purposes as a dementia treatment substance and cannabis can be used as a positive tool.

  • Current many software development projects gradually develop large volume of complex and changeable system. Architecture driven methodology is used for developing softwares like CBD (Component Based Development) or PLE (Product Line Engineering). To improve the development and maintainability in such an environment, the first of all needs the flexible and extensible architecture. This paper suggests the CBD application framework that has the flexbile and extensible architecture for improving development productivity and maintainability. In this paper, we also show basic performances of our suggested framework, comparing to a well-known web application framework, Struts.

  • 대부분의 응용 시스템들이 인터넷과 웹 기술을 기반으로 개발, 운영됨에 따라 상호운영성을 허용하고 동적 변화에 민첩하게 대응할 수 있는 소프트웨어 개발을 위한 방법론 및 툴 지원이 요구된다. 이에 따라 컴포넌트 기반의 소프트웨어 개발(CBD : Component Based Development)은 소프트웨어 시스템 구축을 위한 가장 이상적 전략으로 인식되고 있다. CBD 개발을 지원하기 위한 컴포넌트 저장소는 컴포넌트의 개발과 유통, 활용을 위한 컴포넌트 및 관련 모든 프로덕트 정보들의 통합적인 관리 중심체이다. 그러므로 효과적인 CBD의 전개를 위해서는 정규화된 컴포넌트 참조 아키텍쳐에 기반한 저장소 구축은 필수적이다. 본 논문에서는 CBD 방법론에 의한 컴포넌트 저장소 구축을 목적으로 저장 아키텍쳐를 제시하고 이를 기반한 저장소 프로토타이핑을 개발한다. 이를 위해 컴포넌트 기능성 영역의 수직적 관점과 라이프사이클 관점의 수평적 관점이 혼합된 아키텍쳐를 정의하고 이에 식별, 정의되어진 컴포넌트를 적용한다.

  • Defence Information System has surely required the guarantee of interoperability between systems as performing task oriented functions. To improve interoperability between them and use the benefits of component based development, defense officers are planning to develop COE like a kind of component bank concept. Defense component development methodology(ADDMe) within COE is a new approach of component based methodology for Defense environment after comparing, analyzing, and synthesizing with traditional CBDs. In this paper we introduce advanced defense component development methodology(ADDMe) and present checklist for improving interoperability between Defence component based systems which are developed with ADDMe. With our proposed interoperability's checklist, we can improve interoperability of defense component based systems through applying per each phase of ADDMe.

  • 마자인(麻子仁)은 뽕나무과에 속하는 대마(Cannabis sativa L.)의 종자로써, 治血虛津虧, 腸燥便秘하며, 中風汗出, 逐水, 利小便, 破積血, 復血脈, 乳婦産後餘疾, 長髮 등에 사용한다고 기록되어 있다. 마자인 종자의 외피에는 환각성분인 Tetrahydrocannabinol (THC) 및 뇌전증과 다발성경화증 등 희귀, 난치성 질환의 치료제로 사용되는 Cannabidiol (CBD) 성분이 함유되어 있다. 따라서 외피를 제거한 마자인은 햄프씨드(Hemp Seed)로써 식품으로 이용되지만, 외피를 제거하지 않은 마자인은 의약품으로써 사용이 되고 있다. 마자인은 윤조탕, 자윤환, 마자인환 등 다양한 한의학 처방에 사용되지만, 외피에 함유되어있는 THC 및 CBD의 함유량 및 안전성에 대한 연구는 밝혀지지 않았다. 이에 마자인 함유처방의 안전성을 입증하는 실험방법을 설계하였다. 우선 의약품으로 유통되는 마자인의 외피에 THC 및 CBD 성분이 있는지를 확인하기 위해 마자인을 다양한 용매별 (물, 헥산 등)로 추출한 후 LC/MS를 이용해 성분 유무를 확인한다. 또한, 마자인 함유 처방 (마자인환, 자윤환, 윤조탕 등)을 복용하였을 경우 혈중에 THC 및 CBD 성분이 있는지를 확인하는 방법으로 실험동물에 마자인 함유 /처방을 투여한 후 혈액을 채취한다. 마찬가지로 성분 유무를 측정하는 방법은 LC/MS를 이용해 확인한다.

  • Typical Cu(In,Ga)Se2 (CIGS)-based solar cells have a buffer layer between CIGS absorber layer and transparent ZnO front electrode, which plays an important role in improving the cell performance. Among various buffer materials, chemical bath deposition (CBD)-ZnS is being steadily studied to alternative to conventional CdS and the efficiency of CBD-ZnS/CIGS solar cell shows the comparable values with that of CdS/CIGS solar cell. The intriguing thing is that reversible changes occur after exposure to illumination due to the metastable defect states in completed ZnS/CIGS solar cell, which induces an improvement of solar cell performance. Thus, it implies that the understanding of metastable defects in CBD-ZnS/CIGS solar cell is important issue. In this study, we fabricate the ITO/i-ZnO/CBD-ZnS/CIGS/Mo/SLG solar cells by controlling the NH4OH mole concentration (from 2 M to 3.5 M) of CBD-ZnS buffer layer and observe their conversion efficiency with and without light soaking for 1 hr. From the results, NH4OH mole concentration and light exposure can significantly affect the CBD-ZnS/CIGS solar cell performance. In order to investigate that which layer can contain metastable defect states to influence on solar cell performance, impedance spectroscopy and capacitance profiling technique with exposure to illumination have been applied to CBD-ZnS/CIGS solar cell. These techniques give a very useful information on the density of states within the bandgap of CIGS, free carriers density, and light-induced metastable effects. Here, we present the rearranged charge distribution after exposure to illumination and suggest the origin of the metastable defect states in CBD-ZnS/CIGS solar cell.

  • In this study, one GRAS strain was screened from doenjang, a traditional Korean fermented food, as a microorganism producing amylase due to the formation of a clear zone on the medium including soluble starch. From the analysis of the gene sequence of 16S ribosomal RNA, the strain was identified as Bacillus subtilis and was therefore named Bacillus subtilis CBD2. When the nutrient broth medium was prepared with 3% NaCl, 5% glucose, and the initial medium pH 7.0, the B. subtilis CBD2 showed maximum growth. Among soluble starch, corn starch, maize amylopectin, and wheat starch, soluble starch was the most effective carbon source in the production of amylase by B. subtilis CBD2. The amylase from B. subtilis CBD2 showed the highest activities at pH 8.0 and $50^{\circ}C$, and corn starch was the most proper substrate for the enzyme activity. When corn starch was used as a substrate, the production of sugars through enzyme activity increased for 24 h, and then the enzyme activity became constant.

  • This paper is to understand the impact of systematic risk on capitalization rate at office building market and retail real estate market in Seoul and to see if CAPM(Capital Asset Pricing Model) is applicable. For this, this paper considers eight different office building and retail real estate markets in Seoul city area, called GBD, YBD, CBD, and Other Business District, and GBD, SBD, CBD, and Other Business District, to find out if there is any positive-linearity between systematic risk and capitalization rate for each business district not. Then, this paper tries to verify applicability of CAPM to four office building markets and four retail real estate markets with Black, Jensen, and Scholes(1972)'s statistical methodology. At last, the result shows that there is positive linearity between systematic risk and capitalization rate only GBD except Others(YBD, CBD, and other business district) in office building market. In addtion, SBD and CBD, they could be figured out that it is not efficient market because increasing systematic risk declines capitalization rate in retail real estate market. However, CAPM is not applicable in all office building(GBD, YBD, CBD, and other business district) and retail real estate markets(GBD, SBD, CBD, and other business district) in Seoul.
