제조업에서는 품질관리가 잘 이루어지고 있는 가운데 우리나라 건설업에서는 1996년에 성수대교의 파괴 1997년의 삼풍 백화점의 분괴, 그리고 올해에 들어서도 지하철의 대 화제 등 건설업에 관련된 사건들이 많다. 건설업에 있어서는 품질 관리에 어려움이 많고 제대로 이루어지고 있지 않다. 이것은 제조업에서는 타 업체와 경쟁하기 때문이다. 품질이 안 좋으면 제품이 안 팔리기 때문에 업체는 열심히 품질을 개선하려고 한다. 그러나 주문생산 일품생산의 건설업에서는 제품의 단일성, 복잡성 등의 제반문제와 함께 주문생산 등, 주문을 받기만 하면 일정 규준에 합격만 하면 되기 때문에 더 이상 품질개선에 노력을 기울이지 않는다. 품질을 개선시키기 위해서는 기술적인 측면과, 문화적, 교육적인 측면에 크게 나눌 수 있다. 이 논문에서는 교육적인 측면 특히 평가방식에 대해서 연구하였다. 건설업에서는 어떤 평가가 이루어지고 있으면 품질개선을 위해서는 어떤 평가가 시행되어야 하는지 제지하였다. 지금까지는 건설업의 특수성, 복잡성 때문에 품질평가가 도입되어지지 않았으나, 한국의 건설업의 제품의 질을 높이려고 한다면 지어진 제품의 품질을 평가함으로써 경쟁시키는 것이 유익한 방법이다. 건설업체들이 자사제품의 품질을 개선하려고 수수로 노력을 하게 될 것이다.

It is vital to understand the changing characteristics of interphase microbial communities and interspecies synergism during the fermentation of Chinese liquors. In this study, microbial communities in the three indispensable phases (pit mud, zaopei, and huangshui) of Luzhou-flavored liquor manufacturing pits and their shifts during cellars use were first investigated by polyphasic culture-independent approaches. The archaeal and eubacterial communities in the three phases were quantitatively assessed by combined phospholipid ether lipids/phospholipid fatty acid analysis and fluorescence in situ hybridization. In addition, qualitative information regarding the microbial community was analyzed by PCR-denaturing gradient gel electrophoresis. Results suggested that the interphase microbial community profiles were quite different, and the proportions of specific microbial groups evolved gradually. Anaerobic bacteria and gram-positive bacteria were dominant and their numbers were higher in pit mud ($10^9$ cells/g) than in huangshui ($10^7$ cells/ml) and zaopei ($10^7$ cells/g). Hydrogenotrophic methanogenic archaea were the dominant archaea, and their proportions were virtually unchanged in pit mud (around 65%), whereas they first increased and then decreased in zaopei (59%-82%-47%) and increased with pit age in huangshui (82%-92%). Interactions between microbial communities, especially between eubacteria and methanogens, played a key role in the formation of favorable niches for liquor fermentation. Furthermore, daqu (an essential saccharifying and fermentative agent) and metabolic regulation parameters greatly affected the microbial community.

RFID has fundamental influences on today's business management. This research seeks to formulate the opportunities and challenges, the strengths and weaknesses and the perceived benefits of RFID implementation in three industries: manufacturing, medical-service, and distribution. Ten companies of successful RFID deployment in Korea are presented. Field interview and panel discussion were used to explore the research purpose. The core challenges include RFID readability issues, lack of best practices, increasing prime cost, visible ROI, implementation cost, and employee's resistance. The strengths include IT infrastructure, system integration competency, RFID business model creation ability, executive's support. There is little weakness in Korea companies, there are many perceived benefits in three industries. The most distinctive finding is that the visible ROI was found out in the manufacturing industry, not in the distribution industry. The opportunities and challenges, the strengths and weaknesses and the perceived benefits are some different in three industries, which provide valuable guidance for Korean companies in seeking the RFID opportunities. This case study represents a pioneer research of RFID adoption in Korea.

This study aims to analyze the effects of trade on human capital accumulation and economic growth in Korean manufacturing industry. The results of empirical analysis by dynamic panel model are as follows. The increase in exports of skilled labor intensive industries has a positive effect on human capital and economic growth, and the impact of import on human capital accumulation and economic growth has alst a positive impact. The exports of unskilled intensive labor industries have a negative impact on human capital accumulation and economic growth. Imports of unskilled labor intensive industries have negative on human capital accumulation and economic growth. It is difficult to derive statistically significant results for the effects of trade on human capital accumulation and economic growth before and after 2008. However, as a result of the financial crisis in 2008, it seems that the effects have decreased since 2008.

Taylor and Ford in the 1910s led to the "scientific management" for the entire industry from the manufacturing spread of TQM Total Quality Management has been structured as a management efficiency, such as 6-Sigma techniques were developed. SW development also introduces the idea, such as CMMI and SPICE-based process management, management practices have evolved. However, in recent years to increase the knowledge of workers in the manufacturing process oriented management approach is under serious challenge. Business performance or productivity will be varied depending all motivation, human relationship, job involvement rather than simply putting a lot of time. Especially in the SW industry which is depending on human resource, Creativity should be limited in traditional management methods. Recently, Google and Apple, Cisco and global advanced companies adopt a human relationship management. Their productivity and creativity in product development has been successful by giving autonomy and motivation, enthusiasm and vision to tile employees. Human relationship management since the mid-1990s, appears as a new paradigm so called Agile process in the field of SW development. Agile processes emphasis on light, flexible and responding to changes immediately in the business environment step away from traditional management approach which is the heavy and complicated process. In this paper, agile project management concepts and practices which is applied to industry will be examined.
