소비자 보호 및 효율적 자원배분, 기업의 안전증진 유인제공, 제도의 국제적 조화를 위하여 제조물책임법(製造物責任法) 제정의 필요성이 제기되고 있다. 현재 제조물로 인한 사고는 민법(民法)에 의하여 보상받고 있으나 그 입증책임이 과중하고, 현재 우리나라 생산물배상책임보험(生産物賠償責任保險)이 전체 손해보험에서 차지하는 비중은 0.1%에 불과(미국 10%)하여 그 비용이 아직 미미하므로 제조물책임법제(製造物責任法制) 도입의 안전증진효과가 경제적 손실보다 클 것으로 예상된다. 법제정시의 기본방향은 소비자에게 단순히 보상을 제공하는 법제가 아닌, 기업의 책임과 제품결함이 밀접히 연관되어 배상(賠償) 및 사고억제(事故抑制)의 유인과 효과를 극대화하는 것이어야 한다. 추정규정의 도입은 소비자(消費者) 피해구제(被害救濟)를 용이하게 하지만, 디자인 및 경고결함(警告缺陷)과 결합되면 제조자가 제품사고의 모든 가능성에 대해 완벽한 정보를 가지지 않는 한 제조자의 책임이 되어 제조물책임(製造物責任)의 불확실성(不確實性)을 높이고, 결과적으로 기업에게 절대책임(絶對責任)을 부과하게 되어 제품개발과 혁신을 위축시키는 등의 부정적(否定的) 영향을 초래할 위험이 크다. 따라서 결함의 추정은 인정하지 않아야 하며, 제품개발 및 혁신을 도모하기 위해 개발위험항변(開發危險抗辯)은 인정되어야 한다. 손해배상액(損害賠償額) 상한(上限)을 두지 않는 것이 경제적으로 효율적이고 연대책임을 인정하여 유통업자의 안전제고유인(安全提高誘因)도 강화하는 것이 효과적이다. 중소기업을 포함한 모든 기업에게 입법후 1년 정도의 준비기간(準備期間)을 주는 것이 바람직할 듯하며, 배상책임보험(賠償責任保險)은 의무화하지 않는 것이 경제적으로 효율적이다. 기계, 전자, 운송용기기, 건설, 화학, 식 의약품, 가스제품, 완구, 운동용구 등이 영향을 크게 받을 것으로 예상되지만 법제이용(法制利用)의 편의가 개선되기 전에는 소송의 증가는 미미하리라 예상된다.

This paper empirically examines multiskill formation as a critical mechanism of human capital accumulation within the firm. We investigate various factors that foster multiskill formation of the employees at the workplace. We also investigate whether and how multiskill formation of the employees, in tum, affect the labor productivity. Our empirical results are summarized as the following. First, skills of the employees are developed along the sequential path rather than the parallel path. They evolve from the simple-skill to the single-skill, and then to the multi-skill state. Second, multi skilling is stimulated by uncertainty factors of the environment and various human resource management practices such as mutual learning among workers, workers' participation in decision making, and job rotation. Third, the increase in the ratio of multiskilled workers in the firm has a positive impact on the growth of the firm's labor productivity. Our analyses show that the labor productivity growth increases by 0.019 with the increase in multi skilling ratio by 0.1. Fourth, uncertainty and human resource management practices had an indirect impact on labor productivity growth only through multiskilling. These results strongly indicate that multiskilling is a result of human capital accumulation fostered by various human resource management practices.

This study explored the patterns of activities and interactions among participants in the adoption process of a new system innovation, ADSL, in Korea, using an integrative framework of innovation system and strategic decision-making process for uncertainty reduction. An in-depth case analysis was undertaken to identify the adoption process of ADSL innovation, as a case in point, in conjunction with activities and interactions among related parties such as government, service providers, equipment suppliers, and content providers. The results of case analysis revealed that as the level of uncertainty in the adoption of ADSL innovation decreases, the focus of decision-making activities moves from scoping, to searching, to evaluating and to committing. Also this study found that at the early stage of ADSL adoption with higher level of uncertainty, government plays a pivotal role in coordination of related parties to participate in the innovation process, while service providers replaced this role at later stage of innovation with lower level of uncertainty. This study discussed theoretical and policy implications for the adoption of new system innovations with varying degrees of uncertainty.

At the planning and design stages of a development of underground space or tunneling project, the information regarding ground conditions is very important to enhance economical efficiency and overall safety In general, the information can be expressed using RMR or Q-system and with the geophysical exploration image. RMR or Q-system can provide direct information of rock mass in a local scale for the design scheme. Oppositely, the image of geophysical exploration can provide an exthaustive but indirect information. These two types of the information have inherent uncertainties from various sources and are given in different scales and with their own physical meanings. Recently, RMR has been estimated in unsampled areas based on given data using geostatistical methods like Kriging and conditional simulation. In this study, simulated annealing(SA) is applied to overcome the shortcomings of Kriging methods or conditional simulations just using a primary variable. Using this technique, RMR and the image of geophysical exploration can be integrated to construct the spatial distribution of RM and to evaluate its uncertainty. The SA method was applied to solve an optimization problem with constraints. We have suggested the practical procedure of the SA technique for the uncertainty evaluation of RMR and also demonstrated this technique through an application, where it was used to identify the spatial distribution of RMR and quantify the uncertainty. For a geotechnical application, the objective functions of SA are defined using statistical models of RMR and the correlations between RMR and the reference image. The applicability and validity of this application are examined and then the result of uncertainty evaluation can be used to optimize the tunnel layout.

Nitrate contamination problems from groundwater supplies have been documented throughout many countries in the world, including Korea. Nitrate salts can induce methemoglobinemia and possibly human gastric cancer. In farmed areas. intensive agricultural activities have caused a major increase in nitrate loading to groundwater. To determine whether decision makers must take farm-management actions to control the increase of groundwater nitrate concentration and to decide the timing of such actions, it is important to predict groundwater Nitrate levels that would result over time from various farm-management practices. However, the input values such as soil, fertilizer and crop data) used to examine the effects of various farm-management practices on groundwater nitrate level are usually uncertain due to a lack of available information. In this paper. the ease of a community with a nitrate water quality problem is illustrated to examine the effects of various farm-management practices and to show bow to perform, with uncertain information. a time-series analysis on groundwater nitrate levels that would result. from each farm-management practice.

2011년 동일본 대지진으로 발생된 지진해일로 인해 막대한 경제적 손실과 인명피해가 발생하였고, 2차적 사회적 피해가 지속되고 있다. 또한 국내에서도 최근 경주와 포항지역에서 지진이 발생하여 피해가 발생함에 따라 재난의 불확실성에 대한 대비의 중요성이 강조되고 있고, 과거 안전하다고 했던 재난에 대한 위험성에 대해 국민들의 관심이 증대되었다. 피해사례가 2차례 있는 지진해일의 경우도 동일본 대지진 이후로 전 세계적으로 해일에 대한 위험성이 재평가되고 있다. 지진해일은 해저에서 발생하는 지진에 의한 것으로 발생지점 및 강도 등을 예측하기가 쉽지 않으므로, 지진발생에 대한 가상 시나리오를 이용한 연구가 진행되고 있다. 가상 시나리오를 활용하여 현재까지 많은 침수예상도가 제작되었으나, 다양한 시나리오 대해서 검토되지 않았다. 따라서 본 연구에서는 과학적 보간법을 이용하여 수치모형을 수행하지 않고 기수행된 연구 DB를 활용하여 지진해일 피해를 예측하는 기술을 개발하였다. 연구 DB는 국립재난안전연구원에서 수행된 지진해일 자료를 활용하였고, 전국단위를 기반으로 지진규모 7.0~9.0 내에 지진해일을 유발하는 지진에 대해 지진해일의 피해를 예측할 수 있는 기술을 개발하였다. 기술을 검증하기 위해 5개의 진원지에 대하여 과거 발생 지진규모부터 극한의 지진규모를 가정한 수치모의 결과와 본 연구의 결과를 비교하였다. 본 연구는 격자 1km인 광역모형의 모의결과를 활용하였으므로 실제로 해안지역의 침수양상의 정확도가 높지 않지만 향후 고정밀 공간해상도에 대하여 모의를 수행한다면 지진해일로 발생하는 범람 및 침수를 보다 정밀하게 예측할 수 있을 것이라 기대된다.

This study aimed to introduce research on coerced debt victimization and interventions in the context of domestic violence. To achieve the aim, this study reviewed existing studies on coerced debt conducted in the US. This study discussed the followings: First, coerced debt was theorized by coerced control theory of domestic violence and control mechanisms of economic abuse and conceptualized as fraud and force. Second, the effects of coerced debt included credit damage, economic dependence, and barriers to housing, employment, and safety. Third, to intervene the victimization, service providers should endure uncertainty and its time consuming process of recovering, provide an intense and personalized advocacy, and overcome the problems of absence of policies to support the victims. Finally, service providers should have educations and training programs on the assessment and intervention skills of coerced debt acknowledging empowerment and safety of the victims as the most important.

Recently as globalization of financial capital is progressed, possibility of crisis and unreliability of world economy is more growing. Korean economy required radical restructuring because of the financial crisis and the economic changes occurred in that process. This study is to explain the economic changes of Gwanagju city is produced by the financial crisis of Korean economy The most important industries are service and transportation equipment in Gwangju city. These industries began to decrease after financial crisis but machinery equipment, electrical machinery & electronics and rubber goods & plastic industry is growing relatively. Because of the decrease of service, the economy of inner city which service industry relatively agglomerated in is reducing. And agglomeration space for the optical photonics industry was built up by the upbringing policy of government on high-technology industry to overcome the economic crisis and micro industrial space such as venture building and establishment nursery center was built up. But high-technology industries have many geographical limits to embed in Gwanagju city, so there needs to construct regional innovation system for knowledge based economies

The purpose of this study is to estimate the value of the sociocultural multifunctionality of rural areas in Korea. The sociocultural multifunctionality of rural areas consists of emotional comfort, green landscape, cultural heritage, and rural viability values. The value of the sociocultural multifunctionality was assessed by contingent valuation method incoporating preference uncertainty. The log-logit models indicated that households were willing to pay 14,027~26,757 won per month and the model with preference uncertainty gave the highest WTP. WTP was affected by respondent's sex, location, awareness of relation with multifunctionality and others. The total value of sociocultural multifunctionality of rural areas in Korea estimated to 2,691~5,134 billion won per year.
