산업사회를 구성하고 발전 변화시키는 가장 중요한 힘은 과학과 지식이다. 그러므로 과학지식의 구조와 그림자는 현대사회의 구조와 과제에 그대로 반영된다. 한국과학저술인협회는 6월 18일 성균관대학에서 「과학과 사회」심포지움을 갖고 현대과학의 방법론적 특징등을 분석, 현대사회와 현대인이 처한 상황 진단을 모색했다. 이날 심포지움에서는 김경동교수(서울대 사회학과)의「기술과 사회변동」 및 노재식 박사(원자력연구소 환경부장)의 「국가발전과 환경보전」등 논문이 발표되었는데 다음은 그 요지이다.

This study reveals the followings in the Tugan's business cycle thoery. First, Tugan tried to construct a business cycle theory based on his market theory. But Tugan' theory is lack of logical consistency. Second, Tugan's critics as well as defenders did not understand his theoretical error. Underconsumption theorists did not evaluate Tugan's periodical crisis theory while only criticizing Tugan's crisis theory neglected a consumption. Bauer developed Tugan's periodical crisis by using the reproduction scheme including a hoarded money. Hilferding only constructed a theory of crisis properly criticizing Tugan's crisis theory on the basis of Marx's concept of crisis.

위험에 대한 인문사회학적인 고찰은 물리적이고 기술적으로 대응하는데 주력하는 재난관리 연구에 새로운 통찰을 제공하고, 재난관리가 국민들에게 제공되어지는 국가의 서비스라는 측면에서 많은 시사점을 제공할 수 있다. 한국에서의 위험에 대한 인문사회학적 논의는 산업사회의 다음 단계로써 현대사회가 바로 위험사회라는 사회변동론적인 접근을 하는 울리히 벡의 "위험사회론"에 경도되어 풍부한 논의와 발전이 이루어지지 못하고 있다. 루만의 위험사회학은 소통에 기반을 둔 방대한 사회체계이론으로 위험에 관련한 소통을 위해와 위험으로 구별함으로써 현대사회에서의 위험에 대한 인식과 대처에 새로운 안목을 제시함과 동시에 문제점을 파악할 수 있도록 한다. 또한 루만의 위험사회학이 이론적으로 정교한 체계이론에 기반하고 있기 때문에 행위자기반 시뮬레이션을 통하여 위험과 관련된 체계들, 즉, 재난관리체계, 정치체계, 법체계, 경제체계, 환경 체계, 언론체계, 등의 다이나믹스를 이해할 수 있는 토대를 마련할 수 있다.

Wood-culture is new paradigm which is substituted for the cement culture, and the study of wood-culture should keep pace with not only the study of a engineering science but also a sociological study to form a theory system. The purpose of this study is to suggest the method of sociological approach of the wood culture which have not yet tried at home and abroad; in view of structural-functionalism, systemical-functionalism, conflict theory, social-change theory by analyzing cases in Korea. In view of structural-functionalism, social system consists of cognition system, institution system, life system and technology system. These sub-systems fulfill the function of what-should-be, reasonability, reality and development. In view of systemical-functionalism, according to the acknowledgment and spreading proccess of the wood usefulness, wood culture system consists of the individual system, organizational system and the social system. In view of conflict theory, the society which has the wood culture can be classified into three types. The one is society which the traditional wood culture is declining and the cement culture is spreading. The other one is society which the cement culture is declining and the traditional wood culture is spreading. Another is Finally the society which the two type balance with. In view of social-change theory, the society can be classified into three types. The one is society which the wood culture is proceeding to the cement culture. The other is society which the cement culture is proceeding to the wood culture. Another is society which the wood culture changes itself. Finally, from a view of changing level, the society can be classified into three types: the micro-change, the middle-level-change, and the macro-change. It's need to study wood culture systemically in view of engineering and sociological science. And then it will be possible to make 'wood culture theory system'.

To determine the reliable probabilistic distribution model of geotechnical properties, outlier and randomness test for analysis data, parameter estimation of probabilistic distribution model, and goodness-of-fit test for model parameter and probabilistic distribution model have to be performed in sequence. In this paper, the probabilistic distribution model's geotechnical properties of Songdo area in Incheon are estimated by the above proposed procedure. Also, the coefficient of variation (COV) representing the variability of geotechnical properties is determined for several geotechnical properties. Reliable probabilistic distribution model and COV of geotechnical properties can be used for probability-based design procedure and reasonable choice of design value in deterministic design method.

미래 수문 분석을 위한 기후변화 연구는 전 세계적으로 많이 수행되어 왔다. 하지만 불확실성 요소로 인해 연구 결과를 활용하는데 있어 여전히 한계가 있다. 따라서 장기적 측면의 기후변화에 대한 연구와 함께 단기간의 엘리뇨, 라니냐와 같은 자연적 기후시스템의 변동에 대한 연구도 현재 진행되고 있다. 본 연구에서는 IRI 연구소에서 매월 전지구 관측자료로 4-7개월 예측을 수행한 GCM 모형 자료를 활용하여 강우 발생을 예측하였다. 한국의 금강유역을 대상유역으로 하였으며, 계절에 따른 강우 변동성을 고려하기 위해 비동질성 은닉 마코프 모형(Nonhomogeneous Hidden Markov Model, NHMM)을 이용하여 일 강우를 모의하였다. 본 연구 결과는 강우 모의를 통한 자연 재난에 대한 예측의 정확도를 향상시키는 새로운 방법론을 제시하는데 활용될 수 있을 것으로 기대된다.

This study proposed a methodology for evaluating the radar rainfall data, whose basic idea is similar to the analysis of variance in statistics. This method enables us to represent separately the error from the bias and that from the data variability. The proposed method was then applied to two storm events for its evaluation. As results, the error from the bias was found to comprises most of the raw radar data error, which becomes significantly decreased in the quality improved cases. On the other hand, the error from the data variability was rather increased due to the quality improvement procedure. The proposed methodology was found to be effective for evaluating the data quality of a storm event for steps of quality improvement, but has a limitation for comparing qualities of storm events. This limitation should be implemented for its general application.

Terms of trade shocks have been considered one of the main driving forces causing business cycle fluctuations in small open economies. Despite their importance in business cycles of small open economies, it is hard to find a serious study in existing literature investigating their implications on monetary policy under a small open economy. Considering it, this paper studies what form of monetary policy rule is the most adequate for a small open economy where terms of trade shocks are dominant factors in generating its business cycle fluctuations. For this purpose, various implementable monetary policy rules frequently analyzed in existing literature are compared in terms of social welfare levels which they can provide for the economy respectively. Main results of this paper can be summarized as follows. First, for a small open economy where terms of trade shocks are main driving forces of its business cycle fluctuations, the nontradable goods price inflation targeting can provide higher level of social welfare than other traditional monetary policy rules such as the CPI inflation targeting or the fixed exchange rate regime. Second, the social welfare improvement of the non-tradable goods price inflation targeting is more apparent when export goods price shocks are more important than import goods price shocks.

A construction project is a complex process consisting of interdependent tasks. If one task has variation, other tasks will be affected additionally and it is difficult to reach consensus on task variation due to the characteristics of the construction site that is going on quickly and complicatedly. Therefore, this study identified the root cause of task variation in construction process. Adjacent matrix was created with the tasks corresponding to major causes of variation, and the network analysis was performed. The results of social network analysis in the construction process can stabilize the work flow in the complex process and improve the reliability of the process plan and the project performance.

Settlement at reclamation area caused by secondary compression should be considered using spatial evaluating method because the thickness of consolidation layer varies at every location. Probabilistic method can be implemented to evaluate uncertainty of spatial distribution of secondary compression. This study spatially evaluated mean and standard deviation of secondary compression in the overall analyzing region using spatial distribution of consolidation thickness estimated by ordinary kriging method and statistical values of soil properties. And then, the area where secondary compression exceeds a design criterion at the specific time was evaluated using probabilistic method. It was observed that the area exceeding the design criterion increased as the variability of $C_{\alpha}/(1+e_o)$ increased or the probabilistic design criterion 0: decreased. It is considered that the probabilistic method can be used for the geotechnical design of soft ground when a probabilistic design criterion is established in the specification.
