The purpose of this study was to promote the understanding of laboratory notebook's record characteristics through getting a line on the importance of the notebooks which have record, information, communication, and proof functions. To improve the research ethics and cultures, this study was examined and investigated by literature references and survey results. This study analyzed the status of the notebooks in part of laboratory information system of the R&D institutes, paper notebooks for laboratory records management, and the introduction of ELN for digital record. For the notebook's institutionalization, more review is needed to the possibility of involvement in the conflict, evidential requisite and signature by inspector, the limitation of autonomous policy for the notebook's operation, the difficulty of preservation for 30 years, the introduction of ELN and utilization for the notebooks. To improve management and institutionalization for the notebooks, it is needed to the notebook's record for knowledge management and evidential values, support and budget for the notebook's management department, researcher's recognition conversion for the notebooks related to the intellectual property and technology transference, the record method train for the notebooks from the university classes, and the introduction of ELN related to the laboratory information management system or project management system.

어떤 자연언어 문서가 전달하려는 의미는 그 텍스트의 성격에 따라 아주 명확할 수도(예: 뉴스 문서), 아주 불분명할 수도 있다(예: 시). 이 연구는 이러한 '의미의 명확성(semantic transparency)'을 정량적으로 측정할 수 있다고 가정하고, 이 의미의 명확성을 판단하는 데에 단어들의 연쇄(word association)의 확률통계적 성질들이 어떻게 기능하는지에 대해 논한다. 이를 위해 특정 단어가 연쇄체를 형성하면서 발생하는 neighboring frequency와 degeneracy를 중심으로 Markov chain Monte Carlo scheme을 적용하여 의미망('Semantic Hypernetwork')으로 학습시킨 후 문서의 구성 단어들과 그 집합들 간의 연결 상태를 파악하였다. 우리는 의미적으로 그 표상이 분명하게 나뉘는 문서들(뉴스와 시)을 대상으로 이 모델이 어떻게 이들의 의미적 명확성을 분류하는지 분석하였다. Neighboring frequency와 degeneracy, 이 두 속성이 언어구조에서의 의미망 기억과 학습 탐색 기제에 유의한 기질로서 제안될 수 있다. 본 연구의 주요 결과로 1) 텍스트의 의미론적 투명성을 구별하는 통계적 증거와, 2) 문서의 의미구조에 대한 새로운 기질 발견, 3) 기존의 문서의 카테고리 별 분류와는 다른 방식의 분류 방식 제안을 들 수 있다.

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.

In this article, I have summarized and reviewed the concepts and terms surrounding the stamped construction technique, focusing on earthen walls in the Three Kingdoms period. This is because confusion is caused by defining the nature of the earthen walls by using various concepts and terms for each researcher regarding the substance and construction method of the earthen walls. The stamped earth method is a representative ancient civil engineering or construction technique in which a frame is made of plates to form a fortress wall, a fence, and the base of a building, and then soil or sand is poured into it layer by layer and then stamped with a bat to make it solid. Therefore, in order to prove that the earthen wall was built by the stamped earth method, evidence such as a narrow plate, a column for fixing it, long horizontal and vertical wood pieces to support the narrow plate, and traces of pounding the soil must be detected. However, in Korea, there are very few cases where such evidence has been fully excavated, so it is necessary to agree on how strictly the standards for the stamped earth method will be applied. The terms related to the stamped technique mobilized for the construction of the earthen walls were explained with actual examples by dividing the terms related to the concept into terms related to the principle and unit of the stamped plate, and the specific stamped technology. In particular, in Pungnabtoseong Earthen wall, a variety of typical and diverse methods of building the ancient stamped earthen wall were identified so that decisive data could be secured to understand the principles and techniques of the stamped earthen wall. In the future, a more general understanding of the stamped technique will be possible only when more evidence related to it is found in relics other than Pungnabtoseong Earthen wall.

Socio-economic polarization in Korea partly due to recent globalization and industrial restructuring could reduce social mobility significantly through passing down educational achievement to one's children. Under the notion that residential segregation is geographical frame for the reproduction of educational inequality, this research investigates residential segregation by educational attainment and neighborhood disparity with a case study of Seoul. The statistical analyses employed local segregation measures such as Location Quotient and Local Moran's I and a variety of variables that reflect neighborhood characteristics. As a result, it found that there are sharp and clear contracts between low- and high-educational group concentrations/clusters particularly in terms of housing characteristics and educational facilities. This results provide some evidences that support the arguments about the causes of residential segregation by class in Korean Cities.

This paper examines the effect of corporate social responsosibility(CSR) on the firm value. Based on the argument that CSR would play the role of mitigating conflicts between firms and society, I hypothesized that CSR would enhance the firm value. This study used regression analysis with a data set of 733 from 2009 to 2012 using KEJI(Korean Economic Justice Institute) Index. An Index published by KEJI was used as the measure of CSR performance. The results of this study are summarized as follows: First, there is a significant positive relation between CSR and firm value. Second, in the seven-rating items consist of the KEJI Index, most items have the positive relationship with the firm value. These results suggest that firm with higher CSR activities exhibit better financial performance as measured by Tobin's Q.

This paper presents a model for the Minimum Wage Commission's decision process and analyzes the strategic actions of the participants in the process. The Minimum Wage Commission has used two ways of setting the minimum wage. The commission has voted either on the labor's against the management' final proposals or has voted on the public interest commissioners' proposal. According to the model, the minimum wage is determined at a level that is very close to or at a level preferred by the median voter among the public interest commissioners. But the probability of adopting labor or management proposal is ex-ante the same. Empirical evidence from the minimum wage decision process is consistent with the predictions of the model. The probability of adopting the labor's proposal in the minimum wage commission voting is not statistically significantly different from 50%. The model also suggests that the preference of the median voter among public interest commissioners determines the minimum wage level. Since the government appoints public interest commissioners and thus, in fact, the median voters, the government can decide the minimum wage level. This proposition is also consistent with data. The annual growth rate of the minimum wage under the progressive governments is higher than under conservative governments.

The sinking of the Sewol ferry has not only induced an intense conflict in Korean society but also been developed into a sociopolitical issue. This paper divides this accident into five stages and examines the records produced at each stage. The Sewolho Citizen Archive Network and the Ansan Citizen Record Committee began the archiving of Sewol and created the 416 Archives. The records of Sewol are social and political records that hold envidencial and historical value. They can be used to rebuild and recover the wounded community as well as to investigate the truth behind the case. Accident archiving collects materials different to the ones which public archiving does, allowing people to view the incident from a different standpoint. It is also characterized as an archiving of the current issue, social movement and regional community. Accident archiving is a method which ensures credibility and impartiality in memory. In light of Sewol archives, accident archiving can contribute to form mature democracy.

This paper investigates whether the value relevance of unbilled revenue in the construction company is differentiated according to the degree of company's operational efficiency. Unbilled revenue is an item that appears in the assets of the statement of financial position based on the IFRS. It is an item that has a nature of accounts receivable, but it is calculated based on subjective judgment of management. In this paper, we hypothesized that the value relevance of unbilled revenue will be differentiated according to operational efficiency of the construction company. The results of hypothesis test are as follows. First, unbilled revenue has a significant relationship with firm's value, which is consistent with previous research results. Second, the value relevance of unbilled revenue is higher in companies with high operational efficiency. In conclusion, this paper is different from previous researches in that this paper presents not only that unbilled revenue has a value relevance but also provides evidence that it can be differentiated according to the degree of operational efficiency.

The main purpose of this study is to analyse and explain the occupational pattems of Korean immigrants in Auckland, New Zealand, in order to understand how they are adapting to New Zealand society. We analysed the Korean telephone directory from 1992 to 1996 and listings of Korean businesses in the biweekly magazine 'Korea Town'. The bulk of Korean immigration started in 1991 when the New Zealand govemment opened up its immigration doors to non-Europeans. Clearly, recent Korean immigration has experienced exponential growth. The range of Korean's occupations has grown gradually compared to the growth of Korean immigration, from about 20 different kinds of occupations in 1992 to 55 in 1997. In 1992, there were only 37 korean businesses listed, but in 1997, there are about 636-a growth of over 1,600${\%}$. As we analysed all Korean businesses, we found that almost all Korean businesses and occupations have not penetrated the host society economy but reflect typical characteristics of ethnic businesses, in tems of capital, business operation, employees and customers being mainly Korean, Korean businesses are concentrated in the City Centre and North Shore. The concentration in North Shore reflects the concentration of Korean residents in this area, while Korean businesses in the City centre are mostly tourist industries(travel agencies, souvenir shops)and restaurants. The findings of this study closely reflect similar Westem studies on ethnic minority businesses. From this, we can conclude that Korean businesses at the moment reflect the initial stage of Korean communities in New Zealand.
