This study is a fundamental research which suggests some standards that can be used in selecting some advanced materials to be applied in housing space designs. The following conclusions have been drawn from the study. First, it has been discovered that as the residents' quality of life improved, the finishing materials emerged as an important element of housing spaces. It could also be seen that among the finishing materials used in housing spaces, there is recently a growing trend towards various environmentally-friendly advanced materials under the theme of 'the nature' and 'health'. As a result, the need to investigate the standards of discriminatory and efficient housing space designs using advanced materials is on the increase. Second, through the literature and precedent studies, the physical criteria of advanced materials have been classified into five categories: new technology, new manufacturing methods, new materials, complementation and applicability. The main criteria of advanced finishing materials for housing spaces have been classified into four main categories: durability, functionality, economical efficiency and sensibility. By collecting and classifying some key words according to each of these four categories, the representative or combinable features have been extracted. By organizing the advanced materials' physical criteria and their details, some standards based on the physical aspects have been suggested. The features of the finishing materials in consideration of advanced materials have been reclassified into the user-based criteria, environmental criteria and spatial criteria. Through this method, the criteria have been brought up from a new viewpoint, establishing the standards for the advanced materials applicable to housing spaces. Finally, after assessing the criteria by analyzing the advanced materials currently known to be applicable in housing spaces, it has been concluded that the criteria can be used as the fundamental standards. As this study is based on investigating the literature and data, it may be less than reasonable to generalize from the limited number of examples. Hence, it shall be important to make a profound study of some detailed criteria by suggesting more objective standards and analyzing a greater variety of advanced materials.

In this study, we present a new isotope-coded carbamidomethylation (iCCM)-based quantitative proteomics, as a complementary strategy for conventional isotope labeling strategies, with providing the simplicity, ease of use, and robustness. In iCCM-based quantification, two proteome samples can be separately isotope-labeled by means of covalently reaction of all cysteinyl residues in proteins with iodoacetamide (IAA) and its isotope (IAA-$^{13}C_2$, $D_2$), denoted as CM and iCCM, respectively, leading to a mass shift of all cysteinyl residues to be + 4 Da. To evaluate iCCM-based isotope labeling in proteomic quantification, 6 protein standards (i.e., bovine serum albumin, serotransferrin, lysozyme, beta-lactoglobulin, beta-galactosidase, and alpha-lactalbumin) isotopically labeled with IAA and its isotope, mixed equally, and followed by proteolytic digestion. The resulting CM-/iCCM-labeled peptide mixtures were analyzed using a nLC-ESI-FT orbitrap-MS/MS. From our experimental results, we found that the efficiency of iCCM-based quantification is more superior to that of mTRAQ, as a conventional nonisobaric labeling method, in which both of a number of identified peptides from 6 protein standards and the less quantitative variations in the relative abundance ratios of heavy-/light-labeled corresponding peptide pairs. Finally, we applied the developed iCCM-based quantitative method to lung cancer serum proteome in order to evaluate the potential in biomarker discovery study.

This study aimed to find and suggest the purpose of future plans, critical items on designing and Related standards to amend construction standards for domestic energy saving and environmentally friendly housings. It would also activate and increase the supplies of passive house minimizing the problems on current apartment housings in winter and reducing heating energy which brings fine dust pollution. After defining the standard model of Korean apartment housings(reference model), this study calculated the amount of heating energy demand per unit area annually as applying the yearly changed standards from 2008 to 2017 to existing standard model. It turned out that applying 2017 construction standards of energy saving and eco-friendly housings to reference model has saved up to 75% of heating energy demand comparing to the one applied 2008's. However, it still could not solve the fundamental problems such as winter fungus, condensation, freezing, freeze and burst, and insulation weakness space, and could not be free from fine dust particles. To solve them, this study suggested improved standards adding critical items on design related to outside insulation, cut off the heat-bridge, enforce air-tightness and heat change efficiency on heat recovery ventilator. As a result, it has reduced more than 10% of heat demand from 2017. It would be more than 90% of savings from 2008 if we make the amount of heat loss be zero on heat bridge on designing stage in the future.

우리나라는 2015년 환경오염시설의 통합관리에 관한 법률을 통과시켜서 BAT 기준서에 의한 통합환경관리가 실시중이다. 통합환경관리의 성격을 요약하면 다오염물질 배출원에 대한 관리의 통합화와 BAT 로 대변되는 기술적 기준에 의한 규제이다. 일반적으로 경제학에서는 기술기준에 의한 규제는 정태적 동태적 비효율성을 가져오는 것으로서 회피하여야 할 정책수단으로 알려져 있다. 통합환경관리제도는 BAT규제를 바탕으로 운용되는데 이에 대한 경제적 효율성 역시 심각한 의문의 대상이 될 수 있다. 본 논문은 BAT 기준의 효율성을 경제학적 관점에서 평가하고자 시도한다. 간단한 다오염물질 모형을 통하여 BAT 규제의 경제적 효율성을 분석하여 본 결과 단일오염물질상황에서도 정보의 불완전성으로 인하여 약하게 존재하던 환경세의 BAT 대비 비효율성이 다오염물질 상황하에서는 더욱 커짐을 보여주었다. 다오염물질관리체계로서 IPPC와 BAT가 한 묶음으로 추진되고 실행되어온 이유가 이러한 사실에 의하여 부분적으로 설명된다. EU에서 석탄 상대가격의 하락으로 대기오염물질의 배출 증대가 우려되는 상황에서 BAT 기준의 강화로 대처한 것이 가격구조와 실효적 환경세의 변동으로 인한 환경적 후생손실을 BAT 규제 등으로 대처한 사례 중의 하나로 볼 수 있다.

With the recent introduction of supply chain management (SCM), quality management has extended from within companies to between companies. As a result, supply chain quality management (SCQM) has received increased attention. However, existing SCQM studies only focus on what impact quality control in supply chains have on company performance while virtually no studies examine quality control efficiencies. This paper, therefore, evaluated the SCQM efficiency of a parent company and its partner companies by using Data Envelopment Analysis (DEA) based on the Quality Collaboration Index for Supply Chain Management (QCI-SCM) conducted by the Korean Standards Association for its 'Quality Innovation-Based Building and Expansion of Business.' Study results showed that a parent company and its partners showed an overall average efficiency of approximately 80% (parent company 80.37%, partner company 79.05%). By also performing a discriminant analysis based on the calculated efficiency scores using DEA, factors that made companies efficient or inefficient were different between the two groups. In parent companies, efficiency and inefficiency were determined by factors such as communication, infra-structure, support, delivery of quality, and benefit sharing, whereas in partner companies, talent development, infrastructure, crisis management, and delivery of quality were the determining factors. In this paper, we examined the efficiency of SCQM and analyzed them from the perspective of both the parent company and partner companies to offer strategic SCQM insights.

To improve the cost performance of construction sites, various systems and standards are constantly being developed and implemented. Although legal requirements for these system and standard improvements have been increasing, the cost efficiency performance of construction sites remains stagnant. We have digitized documents generated through construction supervision work at 39 building construction sites and proposed a model that can support decision-making in cost efficiency evaluation. This model selects key keywords that are considered to be highly related to cost efficiency by identifying the patterns and relationships of keywords through associated rule analysis and social network analysis using keywords derived from documents. In addition, it is expected to be used as a decision-making aid to determine the cost efficiency of a specific building construction site by establishing a logistic regression model using core keywords. As a systematic database of construction supervision documents and an integrated system of massive data generated by digital technology are established in the future, the accuracy and reliability of the cost efficiency evaluation model are expected to be reinforced.

Purpose Due to the complexity of policy environment in modern society, it is accepted as common basics of policy design to mix up a variety of policy instruments aiming the multiple functions. However, under the current situation of written-down policy specification, not only the public officers but also the policy researchers cannot easily grasp such frameworks as policy portfolio. The purpose of this study is to develop "Policy Attributes Taxonomy" identifying and classifying the public programs to help making decisions for allocative efficiency with effectiveness-based information. Design/methodology/approach To figure out the main scheme and classification criteria of Policy Attributes Taxonomy which represents characteristics of public policies, previous theories and researches on policy components were explored. In addition, to test taxonomic feasibility of certain information system, a set of "Feasibility Standards" was drawn from "requirements for well-organized criteria" of eminent taxonomy literatures. Finally, current government classification system in the area of social service was tested to visualize the application of Taxonomy and Standards. Findings Program Taxonomy Schemes were set including "policy goals", "policy targets", "policy tools", "logical relation" and "delivery system". Each program and project could be condensed into these attributes, making their design more easily distinguishable. Policy portfolio could be readily made out by extracting certain characteristics according to this scheme. Moreover, this taxonomy could be used for rearrangement of present "Program Budget System" or estimation of "Basic Income".
