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.

본(本) 연구(硏究)는 "경제성장(經濟成長)이 재벌(財閥)과 대기업(大企業)에 의한 집중현상(集中現象)을 심화시켰는가?" 및 "재벌(財閥)은 과연 비효율적(非效率的)인가?"라는 두가지 의문에 대하여 제조업을 대상으로 경험적(經驗的) 증거(證據)를 구하였다. 본 연구의 발견 중 가장 중요한 것은, 첫째 대사업체(大事業體) 혹은 재벌부문(財閥部門)이 차지하는 상대적(相對的) 비중(比重)의 하락추세는 고성장기(高成長期)에 더욱 가속되므로 고성장(高成長)을 지속시키는 것이 생산집중(生産集中)을 치유(治癒)하는 유효(有效)한 방안(方案)이라는 시사점과, 둘째 재벌사업체(財閥事業體)가 비재벌사업체(非財閥事業體)보다 평균적으로는 생산성(生産性)이 높지만 생산성격차(生産性隔差)의 세세분류산업별(細細分類産業別) 분포(分布)는 U자형(字型)을 나타내어 비재벌사업체의 생산성이 훨씬 높은 예외산업(例外産業)이 다수 존재하기 때문에, 비효율(非效率)을 근거로 재벌의 기업활동(企業活動)을 규제(規制)하는 정책은 오히려 효율(效率)에 역행(逆行)할 뿐만 아니라 효율성(效率性)을 이유로 재벌규제를 일반화(一般化)하려는 시도 자체가 매우 위험하다는 시사점을 제공하였다. 이러한 발견은 우리경제의 재벌구조(財閥構造)와 경제력집중(經濟力集中)등의 현상을 막연히 비효율(非效率) 차원(次元)에서 접근하려던 일부의 시각을 부정하는 것으로서, 향후 재벌정책(財閥政策)의 목표(目標)가 재정립(再定立)되어야 함을 시사한다.

India has been service-led economic growth during 50 years and turned to the so-called 'service economy' which means that the services sector takes over 50% in GDP since 2000 year. This study aims to find the factors in the existing hypotheses for service economy in India and tries the empirical analysis with the 1953~2003 annual time series data. As a result, the service economy in India has been accelerated by the hypotheses of demand bias, productivity bias and demand increasing of services as the intermediates simultaneously. This implies that the phenomenon of service economy will be continued and furthered in India.

Using a panel data of Korea for $1979{\sim}2002$, this study investigates the determinants of the service sector employment share in Korea. In order to analyze the impact of macroeconomic factors on the service sector's employment share we estimate a simple panel model which is in line with Baumol's model. The panel GMM estimation results show that: 1) The increase in the share of service-related jobs in total employment tends to rise with GDP per capita, which confirms demand-bias hypothesis proposed by Clark. 2) We find that a crucial role in this process has been played by the productivity gap. As Baumol's hypothesis or Baumolis disease, the expansion of the employment share in services relative to industry is the direct consequence of services' lower productivity performances.

이 논문은 중궁의 가족적 특성과 츨상력의 관계를 보다 면밀하게 알아보기 위해 사회 문화적 특성을 근간으로 하는 가구유형을 분류, 이들간의 출산수준을 살펴보았다. 이를 위해 이 연구에서는 1990년에 실시된 제 4 차 중국인구센서스 자료 중에서 조선족이 밀집하여 거주하고 있는 길림성내 연변 조선족자치주의 50% 표본자료를 활용하였다. 가구유형별 출산수준을 분석하기 위해 자료를 가구구성특성에 따라 네가지 유형으로 재구성하였다. 가족경제의 생산단위와 세대구성을 기준으로 고립형, 병렬형, 직계형, 전통형의 네가지 가구유형을 분류하여 각각의 유형별 특성에 따른 차별출산력을 한족과 조선족의 네가지 가구유형을 분류하여 각각의 유형별 특성에 따른 차별출산력을 한족과 조선족을 중심으로 비교해 보았다. 이를 통해 농가와 비농가의 가구형태 또는 세대구성의 성격아 출산수준과 갖는 상관관계와 이에 영향을 미치는 주요 결정요인들을 파악하는데 중점을 두었다. 또한 중국의 사회 경제적요인과 결부하여 전통적으로 유지되던 가족관이 어떻게 변화하고 있는지를 민족별 출산수준을 통해 비교해 보았다. 연구결과 가부장적 가족주의를 해체하고 집단적 공동생산 체제를 대체시키려는 중국의 사회주의 정책이 현실적으로는 가족중심의 생산체제와 전통적 가족주의를 변화시키지 못한 것으로 보인다. 특히 가구유형에 따른 출산수준의 편차는 두 민족간에 차이를 보여 주었다. 한족이 여성의 직업이나 교육수준에 따라 가구유형별 출산수준의 편차가 크게 변화되는 것과는 달리 조선족은 비교적 전통적인 세대관 이 강조되는 다가구 유형에서 높은 출산수준을 나타내는 경향을 보여 주었다. 이는 중국의 인구정책과 경제개방 시행과정에서 약소민족인 조선족의 저출산력과 관련이 있는 것으로 보이며, 이에 따라 가구 유형별 출산수준에 대한 영향력이 한족에 비해 적었던 것으로 지적할수 있다.

In an effort to identify predictors of job performance, research studies in social work administration has been so far on the individual practitioners' levels of knowledge and skills, which could be used in a workplace. As the theoretical concept of organizational environment was fully introduced into social work administration research, however, studies on practitioners' job performance began to have interest in the team or the organizational level variables as well as individual level variables. Along the course of this tendency, this study attempted to test the effect of individual, team, and organizational level variables on the job performance of human service workers. The individual level variables consisted of knowledge, skills, job satisfaction, personality, and counter-productive work behaviors of workers. The team or the organizational level variables included situational constraint, organizational justice, job characteristics, government-dependency, and inter-organizational cooperation. Multi-level complex survey data collected by cluster sampling method from 314 practitioners in 23 organizations were analyzed using Hierarchial Linear Model. Results showed that both task and contextual performance were affected by individual, team, and organizational level variables in various ways.

Purpose This study re-analyzes Jung 2012's data using the time interval based analysis to examine if the process of idea generation is in good currency throughout the ideation sessions. In this way, the relationship between extraversion-introversion personality trait and ideation performance in the context of computer-mediated idea generation can be better understood. Design/methodology/approach A $2{\times}4$ factorial design was used, crossing personality differences (extraversion and introversion) with the degree of stimuli (0, 20, 40, and 80 high-quality ideas). Participants were randomly assigned to one of eight treatment conditions. The group simulator is used to measure individual level performance. The number of unique ideas generated by individuals and the exact time stamp when each idea was submitted were analyzed to compare performances. Findings The results show that introverts' performances significantly drops after about the middle stage of the ideation session, whereas extraverts do not seem to feel time constraints throughout the ideation session, resulting in superior divergent thinking, which is a major key to understand creative productivity in the problem-solving process. Since extraverts tend to yield a larger pool of ideas, another interpretation is that group composition with extraverts compared with introverts may create a logically larger group, which is important to improve the performance of idea generation group.

효율성은 산출물의 가치와 그 산출물을 창출해 내기 위해 생산과정에서 소비한 투입물 가치의 비율로 나타낸다 투입물이나 산출물의 시장가격이 존재하는 경우 이 값을 가중치로 이용하여 산출물과 투입물의 가치를 계산할 수 있다. 그러나 투입물과 산출물의 종류가 다양한 경우에는 투입물의 가치를 적절히 평가하기가 쉽지 않다. Data Envelopment Analysis(DEA)모형은 효율성을 여러 가지 투입물의 가중평균에 대한 여러 가지 산출요소의 가중평균의 비율로 표시하며, 특정 의사결정단위의 효율성 정도는 유사한 투입 산출구조를 가지는 준거집단과 비교하여 상대적으로 측정하고자 하는 방법이다. 본 논문에서는 DEA모형의 구조와 이론적 근거, 그리고 적용상의 장단점에 대해 알아 본 뒤 국내 일선우체국의 운영자료를 토대로 하여 공공적인 성격을 띠는 기관의 운영효율성 측정에의 적용사례를 제시하였다. 투입자료로는 '98년 우정사업자료를 중심으로 공통영업비, 우편영업비, 금융영업비, 직원수, 관할가구수, 관할면적, 고정자산 등 7개 변수와 우편영업수익, 금융영업수익, 보험수지차, 배달 및 중계 우편물량, 현금출납 취급건수, 연평잔실적의 6개 변수를 각각 투입물과 산출물 변수로 설정하여 모형을 구축하였다. 분석대상으로 삼은 64개 우체국 전체의 효율성 평균은 82.14%으로 나타났으며 DEA모형의 효율성결과와 기존에 이미 발표된 정보통신부 평가결과와의 상관관계는 0.46291로 강하지는 않지만 두 변수간에는 정(正)의 상관관계가 있음을 알 수 있었다.

In this article, I outlined the archival management system in Early Joseon Dynasty and examined the characteristics of the system. At first, I explained the three aspects of the archival management; the memory of the past, the documentation of the contemporary, and the vision of the future through the documentation. Secondly, I tried to understand the character of the Veritable Record and its compilation by the concepts of archival science such as 'authenticity', 'reliability'. In the memory of the past, the History of a Dynasty(Koryo-Sa) and the Comprehensive History of Eastern Kingdom were included. The arrangement of the past was accompanied with the systematic study of the domestic and foreign histories. At the beginning of the state building, there was many practical need to the experiences of government and social re-construction. It was also the process of the legitimacy establishment of the new dynasty. And the Bureaucracy promoted the development of the records and archival management system because it needed the continuity and evidence of business. The dualistic structure of the records and archival management system was the most unique character of this age. The management of general administrative records was not different from the modern one. But the historical drafts and the compilation of Veritable record were different. Here, I had to examine the characteristics of these procedures by the concept authenticity, reliability, and custodianship. In doing so, I suggested the need of conceptualization of the historical terms such as 'the primary sources' and 'the secondary sources' in historical study. The archival concepts will be the most useful means to that issue. Through the memory of the past and the documentation of the contemporary, they made visions of the future, new vision of the Literati Governance. In this tradition, in spite of the revision of the Veritable records by the new changed political party, both the orignal and the revised remained as the comparative evidence for the future generation in the name of the Black-Red Revised History.

This research started from bringing up a problem about special situation of the library and information science, which is not easy to investigate its academic characteristics, although it has settled down as a powerful science studying related phenomena as well as education required for the whole process from production of information to consumption of it. Therefore, the purpose of this research is to questingly investigate whether the personal specialty and the experience of taking courses affect recognition of the term 'library and information', and if so, through which channel it influences. In this background, data were collected from 328 students of Chonnam National University for this research, and the following are the analysis results: first, as for the personal characteristics, differences were not generated according to gender and age, but according to scholastic year the results were different; second, as for the experience of taking courses, there were not differences according to whether or not of the experience, but the results varied according to the number and type of the experience; and third, most of the respondents surveyed understood the meaning of a term 'library and information' as the conception of covering the information contained in literature and information of it, regardless of the personal characteristics and the experience of taking courses. Through these results, it can be identified that the term 'library and information' meant in the library and information science is generally understood as expansion of range, rather than chemical combination of literature and information, it is a terminology with various meanings sometimes understood differently according to the special personal experiences, and it also needs scientific investigation of it.
