According to Gerschenkron (1962), the industrialization of relative backward countries was characterized in a systematically varying fashion by sudden spurts. With respect to the technological loaming, its globalization, and the subsequent development of technological capability, Korea, a catching-up nation had some experiences of identifiable discontinuities in her technological development in various industries. This study examines a developmental path of technological catching-up in Korean mobile telecommunication, especially CDMA industry and argues that investment and networking capability play an infrastructural role in accumulating her technological capability. Note that the technological experiences in high-tech industries have made Korea take a different technological path with respect to the previous industrialization. For this purpose, it proposes an analytical framework for examining a developmental path of Korean catching-up players. In addition, it analyzes the case of the Korean mobile telecommunication industry on the basis of the framework, and identifies a developmental path from the case analysis.

RFID is an emerging technology and rapidly applied to various industries due to its high-tech characteristic and convenience. Although RFID provides valuable benefits. it might also generate serious privacy problems. Previous studies show that privacy issues should be incorporated in developing RFID systems and more detailed privacy protection methods. However. they just provide basic concept, rough guideline. and simple architecture about RFID privacy protection. Industry needs more structured framework and detailed systematic process to incorporate privacy issues into the RFID system. The purpose of this paper is to develop a framework and detailed process design of RFID privacy protection issues in retail industries. A framework is developed based on individual sensitivity concept, RFID contents, and interface with EPC global standard. Case study is applied to validate the framework and it turns out to be useful. It is expected that the proposed framework and process design would provide more systematic guide lines to solving RFID privacy problems.

본 연구에서는 개방형 혁신 개념을 활용하여 공공기술이전을 기업의 외부 R&D의 일환으로 간주한 뒤 기술수요기업의 관점에서 공공기술이전의 산업별 특성과 내부 R&D와의 상호작용에 대해 탐구하였다. NTIS 기술료 데이터와 한국기업정보 데이터를 매칭한 뒤 2008년부터 2011년까지 일어난 1,980개 기업의 7,645개 기술이전 자료를 추출, 회귀분석과 분위회귀분석을 실시하였다. 그 동안 기업이 공공기술이전으로부터 얻는 효과가 정성적으로 다루어져 왔으나, 본 연구에서는 산업과 기업의 특성에 따른 효과의 편차를 연구하기 위하여 정량적인 DB를 구축하고 통계적 분석을 시행하였다. 분석 결과 기술이전이 매출성장에 가하는 효과는 중고위기술과 고위기술 분야의 일부 기업들에게 편중되는 경향이 있었다. 또한 기간별(1 2 3년 후) 매출의 경우 기술이전은 기술이전 다음해의 매출에 주로 영향을 주지만, 내부 R&D의 효과는 주로 2년 후의 매출에 집중되어 있는 것으로 분석되었다. 또한 OECD 기술집약도 기준 산업분류와 4개 지정 산업군(자동차, 전자, 반도체, 화학)별로 공공기술이전의 효과에 편차가 있는 것으로 나타났으나, 기업 크기별로는 효과에 유의한 차이가 없었다.

2011년에 촉발되어 전 세계 20여 건에 이르는 Apple과 Samsung의 특허분쟁은 경쟁적 기술전략의 첨예한 양상을 보여준 대표적 사례이다. 두 기업 간 특허소송은 스마트폰 시장에서의 치열한 경쟁구조를 잘 보여준다. 반면, 두 기업은 ICT 및 하이테크 시장 선두기업으로서의 서로 긴밀한 협력적 관계에 있다. 그러나 기존 연구들은 경쟁 또는 협력의 한 부분만을 고려한 나머지 실제 기술경영의 현상을 제대로 진단하지 못했을 뿐 아니라 어떠한 패턴을 보이면서 진화하는지 규명하지 못하였다. 이에 본 연구는 경쟁-협력 동시적 공존의 코피티션(Coopetition) 산업생태계를, Apple과 Samsung의 스마트폰 분쟁사례를 중심으로 분석하고 그 함의와 방향성을 도출하고자 한다. 경쟁관점에서는 두 기업 간 소송자료 및 일지를 활용하여 분쟁의 흐름을, 협력관점에서는 소송에서 쟁점이 된 특허들의 인용정보를 활용하여 핵심기술을 구성하는 지식의 경향과 이전방향을 네트워크 분석방법론을 통해 분석한다.

High-tech microelectronics industry is known as one of the most chemical-intensive industries. In Korea, Microelectronics industry occupied 38% of export and 16% of working employees work in microelectronics industry. But, chemical information and health hazards of high-tech microelectronics manufacturing are poorly understood because of rapid development and its penchant for secrecy. We need to investigate on chemical use and exposure control. We Site-visits to 6 high-tech microelectronics manufacturing company which have cleanroom work using over 1,000kg organic solvents (5 semi-conductor chips and its related parts company, 1 liquid crystal display (LCD)). We reviewed their data on chemical use and ventilation system, and measured TVOCs (Total Volatile Organic Compounds) and carbon dioxide concentration. All cleanroom air passed through hepa filters to acheive low particle levels and only 1 cleanroom uses carbon filters to minimize the organic solvents exposures In TVOC screening test, Cleanroom for semi-conductor chips and its related parts company with laminar down flow system (e.g. class 1~100) showed nondetectable level of TVOCs concentration, but Cleanroom for liquid crystal display (LCD) with conventional flow system (e.g. class 1,000~10,000) showed 327 ppm as TVOCs. Acetone concentration in cleanroom for Jig cleaning, LC Injection, Sealing processes were 18.488ppm (n=14), 49.762 ppm (n=15), 8.656 ppm (n=14) as arithmetric mean. Acetone concentration in cleanroom for LCD inspection process was 40ppm (n=55) as geometric mean, where the range was 7.8~128.7ppm and weakly correlated with ventilation rate efficiency(r=0.44, p<0.05). To control organic solvents in cleanrooms, chemical and carbon filters should be installed with hepa filters. Even though their volatile organic compounds concentration was not exceed to occupational exposure limits, considering of entrance limited cleanroom environment, long-term period exposure effects and adverse health effects of cleanroom worker need further reseach.

Lamination is used extensively in various industries. The type of lamination applied to the material depends on the precision level required, which varies for materials needed for everyday use, materials used in high-tech industries, and processes employed to fabricate finished products. Especially in hot lamination, the distribution of the surface temperature of the heating roller is very important to avoid the generation of internal bubbles and ensure flatness of the attached materials, and thus maintain a good standard of quality and productivity. In this study, we have developed a system to monitor the surface temperature of the heating rollerby applying a heterogeneous controller and a non - contact temperature sensor. This monitoring system accurately measures the surface temperature of the heating roller and applies the RS485 MODBUS communication method for easy expansion. Using this system, a laminated prototype was fabricated, and its efficacy for non-contact temperature sensor calibration, Ethernet IP communication, stoppage of the heating roller, and determination of temperature distribution with rotation was examined for its potential usage in industries.

본 논문에서는 나노셀룰로오스의 일종으로 최근 가장 주목을 받고 있는 소재인 마이크로피브릴화 셀룰로오스에 대하여 살펴보았다. 마이크로피브릴화 셀룰로오스는 리그노셀룰로오스계 바이오매스의 셀룰로오스에서 유래한 섬유로 풍부하고, 재생가능하며, 지속 가능한 천연 소재의 일종이다. 주로 물리적 전처리에 의해 생성되며, 나노미터에서 마이크로미터에 이르는 다양한 소섬유들의 결합으로 이루어져 있다. 이로 인해 마이크로피브릴화 셀룰로오스는 높은 표면적과, 높은 aspect ratio, 그리고 특이적인 용해성을 가지게 되고, 이는 전통적인 목재 산업 뿐만 아니라, 최신식의 식품/바이오/화학/의료 산업에 이르는 다양한 영역에의 적용 가능성을 보여주는 주요한 원인이 된다. 한편 이러한 응용력에도 불구하고, 아직 마이크로피브릴화 셀룰로오스는 제조 시 필요한 높은 에너지량과 반응성 조절의 어려움 때문에 상업적으로 많은 주목을 받지 못하고 있다. 따라서, 마이크로피브릴화 셀룰로오스의 기질에 대한 특성을 이해 및 구체화하고, 마이크로피브릴화 셀룰로오스의 피브릴화도를 선택하며, 표면의 개량을 선택적으로 조절할 수 있는 시스템을 개발하는 연구가 필요할 것이다. 마이크로피브릴화 셀룰로오스가 향후 우리나라의 산업 전반에 걸쳐 활용될 수 있기를 기대해 본다.

This study aims to examine curvilinearly moderating effects of task interdependence on the relationship between demographic faultlines and group performance. It posits that the degree of task interdependence has an impact on the effects of demographic faultlines. It was conducted in six organizations in Korea, their industries including heavy industries, hospital, construction, petrochemical, fine chemicals, and system integration. The survey was distributed to 1330 individuals in 162 teams and 1082 individuals in 137 teams responded to the questionnaire. To test the hypotheses including nonlinear interactions, we conducted a hierarchical regression analysis to the survey data from 82 groups within six firms in Korea. The results show that for groups that experience a high level of task interdependence, the slope for the regression of demographic faultlines on group performance is comparatively low and, at the low level of task interdependence, insignificant. However, at intermediate levels of task interdependence, the association was strongly negative and significant. This study finds that the negative relationship between demographic faultlines and group performance is stronger when task interdependence is moderate than when task interdependence is high or low. Therefore, managers should pay attention to optimal group design by carefully assigning tasks in diverse and divided groups.
