Since 2014, the quality level survey of the defense industry has been carried out annually. The need for this was felt as the quality control policy was inadequately reflected in the survey results. In this study, to secure valid and reliable data, the quality level survey measurement indicators and questionnaires used previously were analyzed and developed as customized papers according to the size of the company. The questionnaire index was simplified through the elimination of unnecessary and redundant items to improve the response rate and reliability. In addition, a comprehensive score was computed based on the improvement index so that the result of the quantitative quality level survey could be calculated. Through this, it was possible to determine the quality level attained by the defense industry. Through the quality level survey, we intend to secure data that can analyze the quality management environment to maintain quality levels of the defense industry and identify ways to establish mid-to-long-term quality management strategies and improve systems to enhance the quality level of the defense industry in the future.

We investigated the effects of breed, laying age, and egg storage period on the vitality of chicks using the Hwanggalsaek Jaeraejong, Korean Rhode Island Red, and Korean White Leghorn chicken breeds. Their eggs were collected during the early laying period (27~29 weeks) and late laying period (50~52 weeks) and were stored for 3 days, 7 days and 14 days. After the eggs hatched, the hatching time, production performance, and organ weight of chicks were investigated. IL-6 gene expression level and relative length of telomeres were analyzed to determine the physiological activity of the chicks. HSP gene expression level and heterophil to lymphocytes ratio were also analyzed to examine the degree of stress response in the chicks. The results showed that breed and laying age influenced the vitality of chicks, but the egg storage period did not. Korean Leghorn chicks were considered the weakest breed in terms of vitality owing to their low survival rate, small heart size, low physiological activity, and high stress response level. Although the survival rate of chicks produced in the early laying period was low, their high physiological activity and low stress response indicated that they had a high vitality than the chicks produced in the late laying period. In conclusion, to obtain chicks with high vitality, it would be desirable to select a high vitality breed and avoid the use of chicks produced in the late laying period.

생산성은 프로젝트를 관리하는데 있어서 효율성을 측정하는 중요한 지표이다 또한 건설 생산성은 비용 및 일정과 연관성이 있을 뿐만 아니라 프로젝트의 성공 여부와도 관련이 크다. 프로젝트에서 생산성의 중요성에도 불구하고 국내에서의 생산성 관련 연구는 생산성에 대한 기본 개념 및 원칙에 관한 기초적인 연구 없이 정량적인 연구에 집중되어 있으며, 관련 데이터 수도 적은 실정이다. 국내 건설 공사의 생산성을 향상시키기 위해서는 생산성 관리의 정량적친 요인뿐만 아니라, 정성적인 요인까지 관리해야 하며, 저하요인에 따른 체계적이고 세부적인 프로세스 및 기법이 제시되어야 한다 이에 국내 건설 공사의 생산성 관리에 린 건설을 도입하고자 한다. 본 연구에서는 국내 생산성 저하요인과 린 건설에서의 Waste 요인과의 상관관계 분석을 통해 국내 건설 공사 현장에서의 Waste 주요 의미를 살펴보고 두 요인간의 상호 관련성을 파악하여, 린 건설의 프로세스 및 기법을 국내 건설 공사 현장에 적용하기 위한 이론적인 근거를 제공하고자 한다.

Recent empirical studies highlight the importance of between-firm or between-establishment factors in rising wage inequality. Examining the establishment-level data from the Mining and Manufacturing Survey of 2000-14, this paper finds that overall between-establishment wage dispersion has increased in Korea. However, unlike other OECD countries, the divergence occured in the lower tail of the wage distribution. Dispersion in labor productivity exhibits a similar movement, therefore explains the widening wage dispersion. In contrast, the link between wages and total factor productivity is much weaker, which appears to be associated with inefficient capital reallocation. I also find much heterogeneity in the productivity-wage relationship across productivity distribution. The most productive establishments turn the smallest portion of productivity gains into wage increases.

The purpose of this study was to review the Gentrification and Development Index in terms of domestic and foreign gentrification. Based on the important indicators of the Gentrification index through previous research, the four evaluation areas were divided into structure and subject, production and consumption, supply and demand, and capital and culture. Looking at the importance of each area, the production and consumption aspects were highest as the important index of the occurrence of gentrification, followed in order by the supply and demand, the structure and subject, and the capital and culture order. From the detailed factors, the report revealed the changes in sales to structure and subject matter, increases in franchises to production and consumption, rises in rent to supply and demand, and transient population to capital and culture to be important items. In addition, an analysis of the gentrification occurrence indicators in urban regeneration project areas revealed high weight in terms of production and consumption, supply, and demand, including the increased franchises, one-person start-ups, higher rents and higher real estate values. In other words, the occurrence of gentrification in urban regeneration areas produces the largest portion of the increases in franchises and rent. Therefore, step-by-step measures are needed through monitoring.

본 연구는 DEA기법을 이용하여 저성장, 저마진, 고위험의 삼중의 어려움 속에서 저비용 고효율의 생산조직과 리스크관리, 건전 여신 정착을 위해 건전성, 생산성, 자본적정성, 수익성이라는 상업은행의 핵심성과지표를 이용하여 효율성을 분석하였다. 분석결과 시중은행과 지방은행 모두 자본적정성에는 효율적이었으나 수익성과 생산성에 있어서는 시중은행이 지방은행보다 효율적이었다.
