삼차원(3D) 프린터의 개발과 보급에 따라 현대의 소비자들은 자신이 원하는 제품을 집에서 3D프린팅 할 수 있는 시대에 살고 있다. 3D프린팅을 통해 소비자 맞춤형 제작이 활성화되기 위해서는 3D프린터와 호환되는 디지털 설계도를 소비자 스스로 제작할 수 있어야 한다. 또한 최적의 프린팅 재질과 온도를 설정할 수 있어야 하고 3D프린터의 유지보수에 비용을 감당해야 한다. 더하여 혹시 있을지 모르는 디자인에 대한 지식재산권 문제에 대응할 수 있어야 한다. 그러나 실상 소비자가 이러한 문제들에 대응하기는 어렵기 때문에 소비자가 원하는 방향으로 3D프린팅을 대행해 줄 수 있는 서비스가 개발될 필요가 있다. 이런 동기에서 출발한 본 연구는 소비자가 원하는 3D프린팅 서비스 방식이 무엇인지에 통찰을 얻기 위해 세계적인 온라인 3D프린팅 제품판매 업체인 Shapeways (www.shapeways.com)에 대한 사용자 경험을 다양한 측면에서 탐색하였다. 그 결과 Shapeways의 사용성, 검색과정, 가격 적절성, 재방문의도, 디자인의 다양성, 디자인 만족도에 대한 양적 평가에서 전반적으로 낮은 평가를 받았다. 또한 다양한 언어지원, 제품 제작과정 공개 및 온-오프라인 사이트 동시운영, 디자이너 중심의 소비자 맞춤형 제작 서비스, 배송 안전성과 제품 내구성에 대한 확신을 줄 수 있는 서비스, 표면의 마감처리 서비스가 필요하다는 건설적인 의견을 통해 소비자 맞춤형 3D프린팅 서비스에 대한 통찰을 획득하였다. 본 연구가 3D프린팅 서비스 플랫폼 개발뿐 아니라, 관련된 산업 및 연구에도 폭넓은 시사점을 줄 것으로 기대한다.

This paper empirically studies the effect of public procurement on small and medium-sized enterprises (SMEs) in the Republic of Korea using firm-level data. Public procurement, the purchase of goods and services from private firms by the public sector, is regarded as an important policy measure for providing support to firms, particularly SMEs. This study uses establishment-level panel data of the mining and manufacturing sectors from the Korean National Bureau of Statistics (Statistics Korea) and procurement history from the Korean Public Procurement Service to empirically estimate the effects of public procurement on firms' productivity (total factor productivity) and survivability. Using a propensity score matching estimation method, we find that participating firms showed higher productivity than non-participating ones in the control group only for the year of participation, that is, 2009. After two years, in 2011, they exhibited significantly lower productivity. In contrast, establishments that participated in public procurement for SMEs in 2009 were more likely to survive than those that did not do so in 2011. These results can be interpreted as the negative consequences of government intervention. The market's efficiency enhancement is hindered if underserving companies survive owing to government intervention but fail to improve efficiency.

가철성 국소의치를 사용하는 환자의 잔존 치아가 우식, 마모, 부식, 파절 등의 이유로 보철 수복이 필요한 경우가 있다. 가철성 국소의치의 구조물과 접촉하는 부분이 많은 지대치의 보철 수복이 필요한 경우, 서베이드 크라운을 제작 후 가철성 국소의치를 새로 제작하는 것이 통상적인 방법이다. 이럴 경우, 환자가 적응하기까지 오랜 시간이 걸리고, 시간적, 경제적 비용이 발생한다. 한편, 손상된 치아 외에 구강 내 다른 부분에서 가철성 국소의치의 지지, 유지 및 안정을 일부분 제공하는 경우 기존 국소의치의 사용은 임상적으로 양호하다. 이 때 기존 국소의치를 유지하면서 해당 치아를 보철 수복한다면, 환자는 불편과 비용을 줄이면서 기존 가철성 국소의치를 사용할 수 있다. 이처럼 국소의치에 맞추어 보철을 제작하는 retrofit crown 제작과정에서 Computer Aided Design-Computer Aided Manufacturing(CAD-CAM)의 발전과 지르코니아의 물리적 성질이 개선되면서 디지털 방식이 적용되고 있다. 본 증례는 하악에서 가철성 국소의치를 사용하는 환자의 지대치가 심하게 마모되어 국소의치에 맞추어 지르코니아 크라운을 제작한 케이스로, 환자와 술자 모두 만족하는 결과를 얻었기에 본 증례를 보고하는 바이다.

Purpose Issues related to information security have been a crucial topic of interest to researchers and practitioners in the IT/IS field. This study develops a research model based on a Structure-Conduct-Outcome (SCO) framework for the social exchange relationship between employees and organizations regarding information security. Design/methodology/approach In applying an SCO framework to information security, structure and conduct are activities imposed on employees within an organizational context; outcomes are activities that protect information security from an employee. Data were collected from 438 employees working in manufacturing and service firms currently implementing an information security policy in South Korea. Structural equation modeling (SEM) with AMOS 22.0 is used to test the validation of the measurement model and the proposed casual relationships in the research model. Findings The results demonstrate support for the relationships between predicting variables in organization structure (security policy and physical security system) and the outcome variables in organization conduct (top management support, security education program, and security visibility). Results confirm that the three variables in organization conduct had a positive effect on individual outcome (security knowledge and compliance intention).

Purpose This study investigates the impact of organizational characteristics on organizational performance through case studies of smart factory implementation in the context of Korean small and medium Enterprises (SMEs). To achieve this goal, this study adopts the smart factory index of KOSMO (Korea Smart Manufacturing Office) established by Korean Ministry of SMEs and Startups. We visited 3 firms implemented smart factory projects. This study presents the results of field study in detail with evaluation criteria on how organizational competences like AI technology adoption and facility automation can be exploited to positively influence organizational performance through smart factory implementation. Design/methodology/approach There are not so many results of empirical studies related to smart factories in Korea. This is because organizational support and user involvement are required for facility AI platform service beyond factory automation after the start of the 4th Industrial Revolution. Korean government's KOSMO (Korean Smart Manufacturing Office) has developed and proposed a level measurement index for smart factory implementation. This study conducts case studies based on the level measurement method proposed by KOSMO in the process of conducting case studies of three companies belonging to the root and mechanic industries in Korea. Findings The findings indicate that organizational competences, such as facility AI platform adoption and user involvement, are antecedents to influence smart factory implementation, while smart factory implementation has significant relationship with organizational performance. This study provides a better understanding of the connection between organizational competences and organizational performance through smart factory case studies. This study suggests that SMEs should focus on enhancing their organizational competences for improving organizational performance through implementing smart factory projects.

E-commerce has not only brought about a great change in the way we exchange goods and services but also revolutionized the way we handle business transactions. In addition, it has a significant influence upon the present business structure, and most of firms in service industry as well as manufacturing are considering adopting E-commerce in a serious manner. Most vessels purchase merchandises through a number of shipping agents. As the amount of harbor materials increase, the number of vessels and their navigation frequency also increase. As a result, the amount of procurement for ships has increased. Traditional means such as telephone and fax to handle ever-increasing harbor transaction, however, has proved to be very time-consuming and cost ineffective. Therefore, people are starting to look for more effective ways. In this paper, an internet-based scheme of B2B transaction is proposed to handle procurement problem between shipping agency and shipping company, and between vessel and suppliers as a more effective approach to streamline such problems. We extract problems of shipping agency through task-analysis and present a scheme that performs decision making and procurement as a system agent with brokering structure. Purchaser and supplier are offered material information rapidly and task loads are minimized by the scheme. Also, the system can support decision making of purchasing goods, and information is shared among purchaser, supplier and system through the system interface.
