제4차 산업혁명은 스마트 제조 시스템의 도입을 통한 제조업 혁신의 개념에서 시작되어, 최근에는 ICT 기술과 다양한 과학기술의 융합으로 발생되는 전 산업의 패러다임 변화의 개념으로 인식되고 있다. 전 세계적으로 제4차 산업혁명의 가능성 및 영향력에 대하여 이목이 집중되고 있으며, 우리나라를 비롯하여 국가 차원의 전략적인 대비를 시도하고자 하는 나라들이 많아지고 있다. 종합적이고 체계적인 관점에서의 제4차 산업혁명 추진 전략을 수립하기 위해서는 선도 국가들의 유사 전략검토가 필요하다고 판단된다. 참고 사례로서 제4차 산업혁명의 발단으로 회자되는 독일의 인더스트리 4.0(Industrie 4.0)을 비롯하여 미국의 첨단제조(Advanced Manufacturing), 일본의 재흥전략 및 로봇 신전략, 중국의 중국제조2025, 영국의 고가치 제조전략(High Value Manufacturing Strategy), 네덜란드의 스마트 인더스트리(Smart Industry) 전략을 들 수 있으며, 이를 토대로 국가 전략 수립에 도움이 될 시사점을 얻을 수 있을 것이다.

Quality assurance with high safety profile is one of the most critical issues to medical device manufacturing. In general, this issue was not paid proper attention with respect to acupuncture needle and its related devices. Acupuncture needles are manufactured through various standards ranging from purely hand-made, partially hand-made and partially machine-made, to fully machine-made mainly in China, Korea, and Japan. There is a large difference in quality between needles from different manufacturers. In order to provide a standard manufacturing guideline, it seems necessary to make a Korean Industrial standard (KS). The authors review this topic from an historical view point, investigate the current situation of the standardization of acupuncture needles in other developed countries, and inspect the general procedure to establish a KS in Korea in order to suggest a KS for acupuncture needles.

It can be acquired the high effective productivity through of high speed, precision of machine tools, and then, machine tools will be got a competitive power. Industrially advanced countries already developed that the high speed feed is 60m/min using the high speed ball screw. Also, a lot of problems have happened the feed drive system. It is necessary to study about the character of positioning accuracy, heat generation and high speed control for feed drive system of high speed. in this study, we make use of the feed drive system with a high lead ball screw. We'll develop the feed drive system at the speed of 60m/min. Using the design of the mechanical element and the high speed control, the basic design concept can be established. After manufacturing one-shaft feed drive system and then conducting the performance test, It'll be analyzed properties of the high speed feed drive system.

Insulators which are used in the domestic electrical industries are mostly depended on importation from some advance countries. Even though insulators which are made of ceramic material have been mostly used domestically, the ratio of usage on composite insulators is recently being increased because of difficulties in manufacturing and high cost regarding ceramic stuffs. In this research, we are trying to develop the composite insulators which are very efficient in insulation regardless of the matter of weight. Even though the technique of manufacturing composite insulator are quite generalized worldwide at the moment, one of the most important issue is to keep security on the know-how that an ingredient of insulated material named 'SF6 gas' is included. Therefore, The aim of this paper is to improve the bonding force and air tight property between two components of composite insulator, Flange and FRP Tube.

Many studies reported that some organizations experience benefits of quality as well as the productivity due to the implementation of ISO9000. However, there are significant differences across countries, industries and organizations. This paper examines the current quality management practices in the Hong Kong construction industry under the ISO 9000 environment by a postal survey. It focuses on the success factors of ISO 9000 implementation in the industry. The findings support the views that changes in the organization are needed to realize the benefits brought by ISO 9000.

Recently, the tendency for young people losing interest in science has accelerated. This tendency is remarkable for not only Japan but also some countries of Asia. It is thought that this tendency was brought from the decrease of the chance to watch the actual manufacturing activities, and the decrease of the real experience which children makes something in their childhood. In order to bring up the capable engineers on such a social background, making a product practice which promotes the understanding of the application of theory for manufacturing products is important in addition to study by the text book. In this study, some practical work materials for the lower grades in the college were developed. Integration of the developed materials and the course of study becomes an effective teaching method of the of subjects on a special field. Arranging this practical work on the learning process makes a high effect of the integrated practical work on the curriculum.

This paper presents a supply chain framework with the ODM (Original Design Manufacturing)-OEM (Original Equipment Manufacturing) hybrid production of textile industry in FTA (Free Trade Agreements) environments between Korea and other countries. The proposed supply chain framework with ODM-OEM hybrid production is a unique supply chain that has both domestic production with non-tariff advantages in FTA environment and oversea production with low labor costs. To investigate the validity of the proposed supply chain, we first construct its strategic profit model and supply chain planning and then show that each member of supply chain network-yarn manufacturer, fabric manufacturer, and apparel manufacturer-can maximize their own profits without conflicts among the members. The efficiency of the ODM-OEM hybrid production system is analytically verified in comparison with the general OEM and ODM production model using profit models. Comprehensive numerical examples are provided to illustrate the advantages of the proposed system.

Metal AM(Additive Manufacturing) has been steadily developed and that is classified into two method. PBF(Powder Bed Fusion) deposited in the bed by the laser or electron beam as a heat source of the powder material and DED(Directed Energy Deposition) deposited by varied heat source of powder and solid filler material. In the developed countries has been applying high productivity process of solid filler metal based DED method to the aerospace and defense sectors. The price of the powder material is quite expensive compared to the solid filler metal. A study on DED method that is based on a solid filler metal is increasing significantly although was low accuracy and degree of freedom.

This paper investigates the effects of TPP on Korean domestic employment. Using data from 1995-2011 obtained from the world input-output database (WIOD) and firm-level data, this paper attempts to identify changes in global value chain (GVC) structures involving Korea and TPP member countries in the Asia-Pacific region. Three stage least squares estimation is employed, and empirical findings show that there exists a statistically positive and significant causal relationship between GVC and domestic manufacturing employment. The positive impacts of TPP on Korean domestic employment suggest that Korea actively encourage TPP negotiation. TPP will bring positive domestic employment effects and opportunities for structural transformation in the manufacturing and services industries in Korea.
