"The certification of compliance of new products of industrial convergence" (hereinafter referred to as "certification of compliance") is a legal certification system in accordance with the Industrial Convergence Promotion Act through which a convergence new product can be officially certified without legislation when the certification standards applicable to the product are not yet provided. Unlike other certification systems, the certification of compliance is characterized by the role of resolving the certification difficulties driven by the regulatory lag of convergence new products. Nevertheless, studies that analyzed the certification of compliance in detail from the viewpoint of regulatory improvement were surprisingly rare. Through the sequential matching of the steps of certification of compliance with the process from the occurrence of a regulatory problem to resolution, our study provided clear understanding as to how the regulatory lag could be reduced by the procedure for certification of compliance. Furthermore, we divided the perspective on regulatory lag management into quantitative and qualitative, and the structures and practices of certification of compliance were then analyzed from the two perspectives. By doing this, the present study emphasized that the fundamental reason the certification of compliance could effectively solve the regulatory lag problem of convergence new products was not only the quantitative elements such as legal deadlines for each step but also several qualitative approaches to securing the quality of every stage.

Asbestos has been actively used for various places. Since it was designated as the first grade carcinogen in the 1970s, strict regulations on using asbestos has been implemented globally. Considering long-term latent periods between asbestos exposure and environmental diseases, we analyze the time lag between asbestos consumption and the incidence of mesothelioma in Korea and estimate the long-run relationship. In addition, we conduct a comparative analysis on the effectiveness of asbestos regulations in the United Kingdom and the United States, which have accumulated long-term time-series observations. The latent period analysis indicates that the consumption of asbestos and the incidence of the disease are highly correlated in all three countries, being long-term lags of more than 30 years. Also, we find a long-run equilibrium relationship between asbestos consumption and the incidence of mesothelioma in the presence of long-term lags between the variables in all three countries. Furthermore, using a distributed lag model, asbestos consumption has statistically significant positive effects on mesothelioma with a long-term lag.

본 논문은 Rogerson의 실질불변감모상각방식 (Real Constant Amortization Schedule)이 가격상한규제 (price-cap regulation)하에서도 사회적으로 최적인가를 규명하는 것을 목적으로 한다. 실질불변감모상각방식이란 피규제기업의 현금의 흐름 (cash flow) - 요율기저에 대한 공정보수와 감가상각액의 합계 - 의 실질가치가 매기에 일정하도록 해 주는 감모상각방식으로서, 이 방식을 사용할 경우 기업은 규제시차의 길이에 관계 없이 최척의 자본-노동비율을 달성하려 한다는 것이다. 실질불변감모상각방식은 통상 사용되는 감모상각방식보다 느린 속도로 자산의 가치를 줄여 나아가는 것으로 알려져 있다. 가격상한규제에 관한 단순한 모형을 구축하여 분석해 본 결과, 수요가 비탄력적일 경우 실질불변감모상각방식은 가격상한규제하에서도 최적자본-노동비율을 유도하며, 가격상한규제는 규제메카니즘에 있어서 투자보수율규제와 유사하다는 결론을 얻을 수 있었다. 그러나, 가격상한규제에 있어서는 소매물가지수의 상승률뿐만 아니라 피규제기업의 효율성제고 효과가 소비자가격의 인하로 나타나는 메카니즘도 중시되고 있다. 즉, RPI-X룰에서 X에 해당하는 부분으로서, 이는 내부효율성의 향상 이외에 기술진보속도도 반영하는데, 이러한 기술진보는 가격상한의 인하요인으로 작용하므로, 피규제기업의 입장에서는 감가상각속도의 적절한 설정이 없는 한 기술진보의 유인이 줄어들 수도 있다. 따라서 기술진보속도와 최적감가상각속도의 관계를 단순한 모형을 확장하여 살펴보았는데, 기술진보속도가 빠를수록 감가상각속도도 빨라져야 한다는 결과가 도출되었다.

In Korea, the transportation & telecommunication service industry is composed of public sector entities, such as public transportation and the postal service, and private sector entities. The public sector may be regulated in terms of pricing or is guaranteed a normal profit. Markup can be a subject for regulation. This paper is to set up the markup equation, estimate the industrial markup, and analyze the markup determinants by estimating the factor price elasticities of markup in the Transportation & Telecommunication industry. The factor price elasticities of markup were estimated to be -0.07 in wage rate, -0.45 in import price index, and -0.13 in interest rates. We suggest that import price and interest rate are major factors to be considered first of all in regulating the transportation & telecommunication industry.

Recently, there has been an increasing number of cases of improving constructability by using electronic detonators with precise delay time in tunnel blasting sites. This case is a case of conducting test blasting using with non-electric detonator and electronic detonator at the site of 『Seoul Metropolitan Area Express Railroad Route A Private Investment Project Section 00』 that requires careful management of vibration and noise. Although this site was designed with a non-electric detonator, it was attempted to improve the advance rate and control vibration and noise by mixing the non-electric detonator and the electronic detonator due to the decrease in the advance rate. As a result of the blasting, the target value was achieved with an advance rate of about 85% and a maximum measured value of vibration and noise is 0.215cm/sec and 73.22dB(A) which were measured below regulatory standards. As blasting works in downtown areas, it is necessary to designate measurement and management objects to continuously manage vibration and noise.

Electronic detonators are widely used in various construction sites due to accurate delay time. Including the cases with exceeded noise and vibration from site using electric/non-electric detonator, electronic detonators are used to improve blast fragmentation or to reduce the cost of secondary partial blasting. Furthermore, the number of cases using electronic detonators are increased for reduction of the cost and construction period by maximizing operations efficiency. This case study is about applying electronic detonators on large section station, tunnel construction site which is the part of urban area GTX A project. Although it was initially planned to utilize non-electric detonators, damage was inflicted on safety-thing. We have considered blasting method using electronic detonators as solution of this problem. By applying electronic detonators, we not only satisfied environmental regulations but also prevented nearby safety-thing from getting damaged. In addition, we were able to shorten the construction period than the initial plan by conducting single simultaneous blasting on large section station, in order to ensure safe and efficient construction.

This study is to reveal structural causal relationship of individual factors influencing association member's substantive payment in the economic view which is a critical factor of project implementation and identify its influence through simulation and actual proof analysis. As the results of analysis, the first, association member's substantive payment is decided to allow for the difference between special price for association members and general price and the profit arising between the time of approval of disposal plan and moving in. The second, on analysis of sensitivity of individual factors influencing association member's substantive payment, floor area ratio applied to project has the biggest influence. Association member's payment is also greatly influenced by the subject of cost allocation for establishing infrastructure in project area. The third, this study set up a structure model based on causal relationship among the factors deciding association member's payment and empirically examined influence and path of influence which the individual factors exercise. The result indicates that control elements and regional characteristic elements influence association member's payment through the medium of plan elements.
