Macroappraisal provides useful means of effective records reduction for archivist in environment of records production on a large scale. In Macroappraisal approach, a appraiser give attention to context of records creation prior to review of records contends and assesses collective records. Moreover, Macroappraisal assesses the significant of the context of contemporary use instead of potential value of research in the future. In Canada, Netherlands and Australia, archivists of national archives has been trying to appraisal public records on the basis of Macroappraisal methodology. Especially, the Canadian archival professional come up with theory and methodology on the Macroappraisal with comparative prominence and trust. This essay proposes to device performance model of Macroappraisal for appraisal of public records in Korea specially, relating to governmental function for national land development planning, on the basis of Canadian approach.

The final goal of the macro appraisal model of Canada is that the figure of society of the day is made by the record. The goal is that we evaluate the meaning documentary have in the social structure of the day to produce records. The organization to be affected much the society is recognized as the organism, 'Government' and the function analysis of the government is emphasized in order to be the documentation. Therefore, it is essential in the macro appraisal model that OPI, the department to carry out the very important function is identified. Also the research of governance about interaction of country and citizen is studied. Based on these studies, the macro appraisal theory is made and it can be macro appraisal methodology that these theory is verified through records. the government of Canada have operated macro appraisal model reflected the figure of the society since 1990's, on adapting the change of the record production of modern. This model of Canada is systemized concretely and the government of Australia introduced the model benchmarking the Canada's. The England and the Holland is bringing up the result of the project introduced the macro appraisal method. Therefore the macro appraisal is the method and the theory noticed globally in the field of appraisal of modern. Throughout the analysis of the macro appraisal system of Canada, how to select the record reflected the figure of the society is proposed, and concrete practice is also present, and concrete practice is also present. Also the improvement method of the appraisal system in Korea is considered.

주식시장에 체계적으로 영향을 미칠 수 있는 거시경제변수(巨視經濟變數)들과 국민경제의 중요한 한 부분인 주식시장(株式市場)의 관계를 구체적으로 규명하는 것은 투자자에게 유용한 정보를 제공하는 동시에 주식시장이 건전한 방향으로 발전할 수 있도록 유도하는 의미 있는 일이다. 본 연구의 목적은 주식수익률의 횡단면적 차이를 설명할 수 있는 경제적으로 유의적인, 즉 '가격화(價格化)'된 거시경제변수(巨視經濟變數)를 발견하는데 있다. 이를 위하여 주식평가모형과 기존의 연구결과를 토대로 주식수익률에 체계적으로 영향을 미칠 수 있는 31개의 거시경제변수를 선정한 후, 실증적 연구방법을 사용하여 우리나라 주식시장에서 '가격화(價格化)'된 거시경제변수가 무엇인지를 확인하였다. 먼저 주식수익률(株式收益率)에 체계적으로 영향을 미칠 수 있는 31개의 거시경제변수(巨視經濟變數)들을 요인분석하여 6개의 공통적 특성으로 압축 요약한 후, 각 차원(요인)을 가장 잘 대표하는 6개의 거시경제변수(대용변수)(巨視經濟變數(代用變數))를 추출하였다. 그리고 요인분석에 의해서 추출된 6개의 거시 경제변수와 주식수익률로 Fama & MacBeth(1973) 방법과 유사한 2단계회귀분석을 실시하여 주식수익률에 유의적인 영향을 미치는 '가격화'된 거시경제변수를 발견하였다. 그 결과, 6개의 거시경제변수 중 산업생산지수증가률(産業生産指數增加率), 회사채류통수익율(會社債流通收益率) 그리고 종합주가지수수익률(綜合株價指數收釜率)등 3개의 거시경제변수가 주식수익률의 횡단면적 차이를 설명할 수 있는 유의적인 또는 '가격화'된 경제변수임을 확인할 수 있었다.

경제정책(經濟政策) 변화(變化)의 효과(效果)를 실증분석(實證分析)할 때, 거시경제(巨視經濟) 변동(變動)에 관심이 있는 경우 거시계량모형(巨視計量模型)을 활용하고, 상대가격구조(相對價格構造) 변동(變動)에 대한 소비자(消費者) 및 생산자(生産者)의 반응에 관심이 있는 경우 일반균형연산모형(一般均衡演算模型)을 사용한다. 그런데 대체로 정책변수(政策變數)는 경제구조(經濟構造)(미시적(微視的) 효과(效果))와 경기순환(景氣循環)(거시적(巨視的) 효과(效果))에 동시적 영향을 주기 때문에, 위의 두 모형(模型) 중 어느 하나만으로는 미시행태와 거시현상을 연계 분석하거 어렵다. 본고(本稿)에서는 정책변수(政策變數)의 변화(變化)가 경제주체(經濟主體)의 개별적 최적화(最適化) 행태(行態)와 집합적(集合的) 행태(行態)에 미치는 영향을 동시에 파악하기 위해 이 두 모형(模型)을 결합한 미시(微視)-거시통합모형(巨視統合模型)을 개발하였다. 통합모형(統合模型)의 결과에 의하면, 일반균형모형(一般均衡模型)에 편입(編入)된 거시계량모형(巨視計量模型)과 동태화(動態化)된 일반균형연산모형(一般均衡演算模型)을 결합하여 단기(短期) 경기순환(景氣循環) 및 중장기(中長期)에 걸친 구조조정(構造調整) 문제(問題)를 동시에 분석 가능한 실증분석(實證分析) 도구(道具)를 개발할 수 있었다. 설제로 본고(本稿)에서는 정책대안효과(政策代案效果)의 정량적(定量的) 평가(評價)를 위하여 통합모형(統合模型)을 가상적인 석탄가격(石炭價格) 자율화(自律化)와 보조금(補助金) 지원제도(支援制度) 변화(變化)의 효과분석에 활용하여 보았다. 이러한 모의실험(模擬實驗)은 다른 정책효과분석(政策效果分析)에도 활용(活用)될 수 있을 것이다.

Due to increased software development cost, interest about the method and automated tool for reusing legacy system have been running high. Therefore, In this study, it proves the definition, concept and also background of legacy system by showing real market and technology trend. Automation tool is designed and developed to handle the concrete development methodology, procedure and reference. Also, we implemented the process that analyze the legacy system and extract, refine, store and reuse the candidate components by using LM(Legacy to Modern System) supporting tool presented in this paper. If LM supporting tool is applied to legacy system migration, we can expect cutting costs, shortening the developing period and succeeding the intellectual property by software re-engineering.

The study aims to explore the alternatives through case analysis in the UK, which is quickly responding with appraisal policies and guidelines appropriate to the digital age. Through a theoretical study, it was confirmed that the concept of appraisal in the digital age was extended to decisions on which records to be created and acquired, and in this context, that the value of records needed to be determined at the earliest point in their life cycle. Furthermore, the advantages of macro-appraisal methods and the inevitability of expanding appraisal groups were outlined. Based on this discussion, the change in the British public record appraisal policy was discussed from a policy perspective, and the current British public record appraisal system was analyzed. Based on the analysis of various policy statements and guidelines, general appraisal criteria, 60 operation selection policies and appraisal processes were discussed. As a conclusion, this study discusses various alternatives to appraisal policies in the digital age.

This paper has studied the monetary policy in Korea with a time varying VAR model using four key macroeconomic variables. First, inclusion of the exchange rate was a crucial factor in evaluating Korean monetary policy since the monetary policy demonstrated sensitivity to exchange rate movements during the crisis periods of both the Asian financial crisis of 1997 and the global financial crisis of 2008. Second, a specification of the stochastic volatilities in TVP-VAR model is important in explaining excessive movements of all variables in the sample. The overall moderation of variables in 2000s was more or less due to a reduction of the stochastic volatilities but also somewhat due to the macroeconomic fundamental structures captured by impulse response functons. Third, the degree of the monetary policy effectiveness of inflation was mitigated in recent periods but with increased persistence. Lastly, the monetary policy stance towards inflation stabilization has advanced ever since the inflation targeting scheme was adopted. However, there still seems to be a room for improvement in this aspect since the degree of the monetary policy stance towards inflation stabilization was relatively weaker than to output stabilization.

IT 기술이 급격히 변화하더라도 새롭게 개발되는 대부분 소프트웨어의 핵심 부분은 기존에 존재하는 소프트웨어를 재사용하여 구현되어지는 경우가 많다. 그러나, 소프트웨어가 최초로 개발된 후 시간이 흐르고 빈번한 수정이 가해지게되면 소프트웨어는 필연적으로 최초의 형상과 많이 달라져 소프트웨어의 효과적인 재사용을 어렵게 한다. 이러한 레거시 소프트웨어를 재사용하기 위해 Refactoring을 적용하여 레거시 소프트웨어를 컴포넌트화하고 이를 재사용하고자 한다. 또한, Refactoring에 관련된 일련의 활동을 Activity로 보고 변경 관리의 대상으로 선정하여 이를 관리함으로써 Refactoring 활동을 평가하고자 한다.
