In the 4th Industrial Revolution and changes in the construction industry market, the importance of information management is becoming more emphasized. For efficient use of information, construction data must be collected, processed and analyzed more quickly and accurately, depending on the purpose of the project. Thus, data could be utilized as integrated knowledge. However, there is a limit to searching or managing construction information produced in various formats over the entire life cycle by index words. Therefore, this study proposes a construction information integrated management plan that reflects the characteristics of the construction industry by applying the OWL concept. For this, as an initial study, an architectural object of small size and clear features was needed. Therefore, a construction information management study using OWL was conducted for Korean traditional architectural style houses (Hanok) which has these characteristics.

Plant viruses are responsible for worldwide production losses of numerous economically important crops. The most common plant RNA viruses are positivesense single-stranded RNA viruses [(+)ss RNA viruses]. These viruses have small genomes that encode a limited number of proteins. The viruses depend on their host's machinery for the replication of their RNA genome, assembly, movement, and attraction to the vectors for dispersal. Recently researchers have reported that chloroplast proteins are crucial for replicating (+)ss plant RNA viruses. Some chloroplast proteins, including translation initiation factor [eIF(iso)4E] and 75 DEAD-box RNA helicase RH8, help viruses fulfill their infection cycle in plants. In contrast, other chloroplast proteins such as PAP2.1, PSaC, and ATPsyn-α play active roles in plant defense against viruses. This is also consistent with the idea that reactive oxygen species, salicylic acid, jasmonic acid, and abscisic acid are produced in chloroplast. However, knowledge of molecular mechanisms and functions underlying these chloroplast host factors during the virus infection is still scarce and remains largely unknown. Our review briefly summarizes the latest knowledge regarding the possible role of chloroplast in plant virus replication, emphasizing chloroplast-related proteins. We have highlighted current advances regarding chloroplast-related proteins' role in replicating plant (+)ss RNA viruses.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, buildings, machines, and other industrial facilities as well as facilities of public enterprises. Particular industrial properties can have longer economic life if their performance is excellent and they are still suitable for current manufacturing needs. If not, its economic life will be shorter. As speed of technological progress becomes rapid, life-cycle and development period of a product is becoming shorter. In an industry characterized by rapid development of technology, industrial properties can become obsolescent faster. Even if they are in good working order, they could be no longer suitable for manufacturing new products based on radically different technology. In our research, we apply engineering approach to estimating functional economic life by factoring in technological obsolescence in such an industry.

The purpose of this paper is to analyze the dynamic characteristics of innovation sources such as scientific knowledges, processing technologies and user's needs in advanced metals technology. The journal articles data of four advanced materials are analyzed; amorphous metals, superplastic materials, shape memory alloys and aluminum-lithium alloy. Some regularities are found from the analysis of the four materials. The innovation proceeds through close interactions among the innovation sources. As the innovation proceeds, the relative importance of each source changes: scientific knowledge initiates the innovation and becomes the most important source in the first phase, then the processing technologies increase importance in the second phase, and then scientific knowledge, again, becomes the leading factor of innovation. Scientific knowledge and processing technology take turns leading the innovation. The impacts of users' needs to the innovation increase more and more as innovation proceeds. The results of analysis imply to the policy makers that emphasis of policy, and therefore the allocation of sources for innovation, should vary along the phases in the life cycle of advanced metals technology.

Imperata cylindrica, a tall tufted grass which has multiple pharmacological applications is one of the key ingredients in various traditional medicinal formula used in India. Previous reports have shown that I. cylindrica plant extract inhibited cell proliferation and induced apoptosis in various cancer cell lines. To our knowledge, no studies have been published on the effect of I. cylindrica leaf extract on human oral cancers. The present study was undertaken in order to evaluate the anticancer properties of the leaf extract of I. cylindrica using an oral squamous cell carcinoma cell line SCC-9 as an in vitro model system. A methanol extract from dried leaves of I. cylindrica (ICL) was prepared by standard procedures. Effects of the ICL extract on the morphology of SCC-9 cells was visualized by microscopy. Cytotoxicity was determined by MTT assay. Effects of the ICL extract on colony forming ability of SCC-9 cells was evaluated using clonogenic assay. Cell cycle analysis was performed by flow cytometry and induction of apoptosis was determined by DNA fragmentation assay. The ICL extract treatment caused cytotoxicity and induced cell death in vitro in SCC-9 cells in a dose-dependent manner. This treatment also significantly reduced the clonogenic potential and inhibited cell proliferation by arresting the cell cycle in the G2/M phase. Furthermore, DNA fragmentation assays showed that the observed cell death was caused by apoptosis. This is the first report showing the anticancer activity of the methanol extracts from the leaves of I. cylindrica in human oral cancer cell line. Our data indicates that ICL extract could be considered as one of the lead compounds for the formulation of anticancer therapeutic agents to treat/manage human oral cancers. The natural abundance of I. cylindrica and its wide geographic distribution could render it one of the primary resource materials for preparation of anticancer therapeutic agents.

지속가능성이란 사회적, 경제적, 환경적인 영향을 전반적으로 고려하며, 인간의 건강과 생활 증진을 내포하고, 환경자원의 보호와 경제적 번영을 의미한다. 지속가능성에 대한 심도 있는 이해는 이러한 환경적인 영향에 대한 고려뿐만 아니라 원료 및 자원채취, 이송, 생산 협력의 전반적인 순환을 다루어야 한다. 화학산업의 지속가능한 발전은 화학공정안전의 발전을 통한 상호보완적인 강화없이 이루어지기 어렵다. 이러한 관점에서 화학공정안전은 국제시장에서 경쟁력 강화의 기회라고도 할 수 있다. 화학공정안전의 변화하는 새로운 패러다임은 현존하는 시스템과 생산공정의 기본 디자인을 고려한 총체적 순환 전 과정으로부터 나온다. 이렇게 화학공정안전을 향상시키기 위해서는 관리 시스템을 포함한 정량적 위험성 평가 방법과 다양한 공정안전 데이터 및 지식베이스를 포함한 통합 스마트시스템의 개발이 필요하다. 본 논문에서는 화학산업안전의 전 과정 순환의 필요성에 대해 언급하였고, 이를 향상시키기 위한 공정안전 신기술에 대해 논의하였다. 변화하는 공정시스템공학에서 사고 없는 지속 가능한 산업의 발전을 위해서는 3 가지의 S, 즉 안전(Safety), 안정(Stability), 안보(Security)의 조합이 적절히 이루어져야 할 것이다.
