The radio frequency identification (RFID) technology allows various forms of applications in many industries including construction. and in Korea, RFID has already been adopted for the use in daily labor control, logistics monitoring of ready-mix concrete, supply chain management of long-lead items, such as structural steel members and curtain walls. Even though RFID tags have varied reading performances depending on various factors including material of tracking target and surrounding environment, there is no information on how much the reading performance of an RFID tag can be achieved against a specific construction components or materials. Therefore, the objective of this research is to identify the actual reading performance of various RFID technologies and to derive a method to maximize the reading performance for the use in the supply chain management process of curtain wall components.

RFID(Radio Frequency IDentification: 라디오 주파수 인식)란 라디오 주파수를 활용해서 무선으로 사물을 인식하는 것을 의미한다. RFID 기술을 구성하는 기본 요소는 태그, 안테나, 리더 등이다. 본 연구에서는 이러한 RFID 기술의 기본 요소와 더불어 인식된 사물의 정보를 광범위하게 구축되어 있는 유${\cdot}$무선 네트워크와 연결하여 활용할 수 있는 모든 기술을 RFID 기술로 정의하였다. 비록 최근에 RFID 기술이 여러 분야에서 큰 이슈로 떠오르고 있지만, 실제 RFID 기술은 오래전인 2차 세계대전에 영국군의 자국 전투기 식별을 위해 이미 활용되고 있었다. 그러나 그 당시에는 RFID 기술의 구성요소인 태그나 리더의 값이 고가였기 때문에 특정분야에 한해 RFID 기술을 적용할 수 있었다. 그 이후에 1990년대에 이르러 RFID 기술은 가축관리, 컨테이너관리, IC 카드 등 점차 다른 분야로 적용이 확대되기 시작했다. 특히 반도체 기술의 발전이 급속도로 이루어진 1990년대 말을 기점으로 RFID 기술에 대한 연구가 활발히 이루어져, 현재에는 SCM(Supply Chain Management), 국방, 의료, 교통, 환경, 동물관리, 홈 네트워크 등 다양한 분야에 적용이 가능한 기술로 평가되고 있다. 특히, SCM에 있어서 RFID 기술 도입은 큰 파급효과가 예상되고 있다. SCM을 구성하는 기업들은 RFID 기술 도입을 통해 제품의 가시성(visibility)과 추적성(traceability)을 확보할 수 있게 된다. 기업들은 자신의 제품이 현재 어디에 있으며 어떠한 경로를 통해 그 자리에 이르렀는지를 실시간(real time)으로 확인 가능하게 된다. 미국의 월마트사(社) 와 영국의 메트로사(社) 같은 선진 유통 기업들은 실증연구를 통해 RFID 기술 도입이 비용 절감과 함께 고객 서비스 향상을 도모할 것이라는 결론을 내린 바 있다. 또한 현제 초기단계이기는 하지만 실제 RFID 기술을 도입하여 운영 중에 있다. 국내에서도 정부주도 하에 RFID 기술에 대한 연구가 활발하게 이루어지고 있으며, 지난 2004년에 유통 물류 분야의 1차 시범사업을 완료하였다. 그러나, 이러한 국내${\cdot}$외의 적극적인 도입 움직임에도 불구하고 국내에서는 아직 RFID기술 도입이 SCM(Supply Chain Management)에 있어서 구체적으로 어떠한 영향을 미치는가에 대한 연구가 거의 이루어지지 못하고 있는 실정이다. 특히 RFID 기술 도입 의사결정자에게 제공될 수 있는 정량적인 ROI 분석 모형에 관한 연구는 시급한 과제로 떠오르고 있다. 따라서 본 연구에서는 SCM 차원에서 RFID 기술 도입에 따른 ROI 분석 모형을 제시하고 적용해 보고자 한다.

This study analyzes the key drivers (commitment, integration of big data, green supply chain management, and green human resource practices) of sustainable capabilities and the influence to which these sustainable capabilities impact the banks' environmental and financial performance. Additionally, this study analyzes the impact of green management practices on the integration of big data technology with operations. The theory of dynamic capability was deployed to propose and empirically test the conceptual model. Data was collected through a self-administrated survey questionnaire from 319 participants employed at 35 banks located in six ASEAN countries. The findings indicate that big data analytics strategies have an impact on internal processes and banks' sustainable and financial performance. This study indicates that banks committed towards proper data monitoring of its clients achieve operational efficiency and sustainability goals. Moreover, our results confirm that banks practising green innovation strategies experience better environmental and economic performance as the employees of these banks have received advance green human resource training. Finally, our study found that internal and external green supply chain management practices have a positive impact on banks' environmental and financial performance, which confirms that ASEAN banks contributing in reduction of environmental impact through its operations will ultimately experience increased financial performance.

Competitive international business environment has forced many firms to focus on supply chain management to cope with highly increasing competition. Hence the supplier selection is the most important decision of a company. Because it has a direct effect on cost reduction and quality, profitability and flexibility improvement of a company, so the right supplier selection significantly affect on the organization's efficiency and effectiveness and competitiveness. The primary research objects of this study is to evaluate an importance of supplier selection factors as an index and to present the evaluation model for supplier selection. For this purpose, this study adopts the AHP method to calculate the importance of supplier selection factors. In this study, 16 factors which affect on the supplier selection decision making are classified into three factors-product supply related factor, product related factor, management ability related factor.

This paper examined the supply chain management Integration factors and environmental performance in Korean industry. Focusing on SCM Integration, GreenSCM practice, and environmental performance factors, purpose of this study is finding linkage between SCM Integration factors with new environmental practice factors and environmental performance. Based on the analysis of eighty-eight cases, the following results were found. First, We found External environmental collaboration factors and Internal environmental monitoring factors within Green Supply Chain Practices. Second, SCM Integration have a positively significant influence on environmental performance. Third, Internal environmental monitoring factors have a positively significant influence on Environmental performance but External environmental collaboration factors doesn't. This study suggests that only with high level of Integration firms may have good result on entire supply chain environmental performance. Finally, our empirical evidence shows that company should be prepared for new environmental trade regulation with Green Supply chain management integration.

Under the international business circumstance, global supply chain management is considered a vital strategic challenge to small and medium-sized enterprises(SMEs) suffering from deficient resources and capabilities to exploit overseas markets comparing with large corporations. That is because they can expand their business domains into overseas markets by establishing strategic alliances with global supply chain partners. Although a wide range of previous researches have emphasized the cooperative networks in the chain, most are ignoring the importance of developing relational characteristics such as trust and reciprocity with the partners. Besides, verifying the relational factors influencing firms' export performances, some studies proposed different and inconsistent factors. According to the social capital theory, which is the social quality and networks facilitating close cooperation of inter-individual and inter-organization, provides the integrated view to identify the relational characteristics in the aspects of network, trust and reciprocal norm. Meanwhile, a number of researchers shows that global entrepreneurship is the internal and intangible resource necessary to promote SMEs' internationalization. Upon closer examination, however, they cannot explain clearly its influencing mechanism in the inter-firm cooperative relationships. This study is to verify the effect of social capital accumulated within global supply chain on SMEs' qualitative and quantitative export performance. In addition, we shed new light on global entrepreneurship expected to be concerned with the formation of social capital and the enhancement of export performances. For this purpose, the questionnaires, developed through literature review, were collected from 192 Korean SMEs affiliated in Korean Medium Industries Association and Global Chief Executive Officer's Club focusing on their memberships' international business. As a result of multi-regression analysis, the social capital - network, trust and reciprocal norm shared with global supply chain partner - as well as global entrepreneurship - innovativeness, proactiveness and risk-taking - have positive effect on SMEs' export performances. Also global entrepreneurship affects positively social capital which has mediating effect partially in the relationship between global entrepreneurship and performances. These results means that there is a structural process - global entrepreneurship(input), social capital(output), and export performances(outcome). In other words, a firm should consistently invest in and develop the social capital with global supply chain partners in order to achieve common goals, establish strategic collaborations and obtain long-term export performances. Furthermore, it is required to foster the global entrepreneurship in an organization so as to build up the social capital. More detailed practical issues and discussion are made in the conclusion.

Our students are shocked by the results that there is an inverse proportion between academic achievement and life satisfaction. Recently, the Organization for Economic Cooperation and Development (OECD) published the PISA 2015 Student Well-Being Report. According to the report, Korean students' education is the highest among OECD countries, but their life satisfaction is the 47th ranked among the 48 OECD and non-OECD countries.[1] This is the cause of the unilateral education using collective achievement in evaluation methods. Therefore, I propose a personalized integrated model utilizing block chain technology. I suggest a personalized education and evaluation system model using selective education and personal approval rather than from teachers' unilateral education. This will no longer open the student's achievement grade system to the public. This change will be accomplished utilizing block chain technology. This technology is characterized by security, transparency and dispersion. The result of this work can be used to improve students' quality of living through a management system of personalized education and evaluation, based on the nature of education.
