This paper adapts the World Bank Regulatory Quality Index (RQI), which is produced annually to provide a better understanding of the effects of regulatory reforms, instead of the Production Market Regulation (PMR) indicators, which are published every five years. We find that 9.9 to 36.0 billion USD worth of regulatory cost could be reduced if the regulatory quality in Korea improves to the level of the OECD average considering that the total burden of regulation in Korea is estimated to range from 2.2 to 357.4 billion USD. The estimated reduction in the regulatory cost accounts for roughly 0.76 to 2.47% of Korea's GDP in 2013, underscoring the importance of regulatory reforms for the Korean economy. This paper introduces a new method with which to examine the distribution of regulatory costs across different industries and firm sizes. This alternative method is largely consistent with the conclusions reached by other studies, specifically that small firms typically bear a disproportionate regulatory burden.

In this paper, we look at the relationship between international trade and the rule of law, using the World Justice Project Rule of Law Index, which include index figures on human rights, limits on government powers, transparency and regulatory efficiency. Based on regression analyses using the rule of law index figures and international trade figures (merchandise trade, service trade, exports and imports as percentage of GDP,) international trade and basic human rights seem to have little relationship; but trade has a close positive relationship with strong order and security. Somewhat surprisingly, regulatory transparency and effective implementation seems to have little or no effect on international trade and vice versa. International trade shows a clear positive relationship with the country's criminal justice system, but the relationship with the civil justice system is not as clear as such. For regulatory implementation and civil justice, services trade positively affect these institutions, but these institutions in turn affect exports more strongly than services trade. Finally, the effect of trade on rule of law is stronger on a medium to long term (10-20 year) time horizon.

Regulatory sentiment refers to the market's subjective evaluation of regulatory reform and is one of the most widely adopted indicators to those charged with implementing and diagnosing regulatory policies. The use of regulatory sentiment in advanced analysis has become universal, albeit it is often limited due to difficulties in articulating consistent and objective quantitative indicators that can meticulously reflect market sentiment overall. Thus, despite ample effort by scholars to read the economic impact of regulatory sentiment in the real economy, causal links are difficult to spot. To fill this gap in the literature, this study analyzes a regulatory sentiment index and economic performance indicators through a text analysis approach and by inspecting diverse tones in media articles. Using different stages of tests, the paper identifies a causal relationship between regulatory sentiment and actual economic activities as measured by private consumption, facility investment, construction investment, gross domestic investment, and employment. Additionally, as a result of analyzing one-unit impulse of regulatory perception, the initial impact on economic growth and private investment was found to be negligible; this was followed by a positive (+) response, after which it converged to zero. Construction investment showed a positive (+) response initially, which then rapidly changed to a negative (-) response and then converged to zero. Gross domestic investment as the initial effect was negligible after showing a positive (+) reaction. Unfortunately, the facility investment outcome was found to be insignificant in the impulse response test. Nevertheless, it can be concluded that it is necessary and important to increase the sensitivity to regulations to promote the economic effectiveness of regulatory reforms. Thus, instead of dealing with policies with the vague goal of merely improving regulatory sentiment, using regulatory sentiment as an indicator of major policies could be an effective approach.

본 논문에서는 국내의 철도 항공 육로를 통한 물류운송산업 규제에 대해 살펴보고 여객 및 화물운송업 규제의 개선이 국민경제에 미칠 수 있는 영향을 계량화하고자 한다. 우리나라의 물류산업은 산출 및 생산규모가 점진적으로 확대되고 있으나 산업구조는 비교적 영세한 편이다. 한편 산업의 규제는 OECD 국가에 비해 높은 수준이며 국내의 여타 산업에 비해서도 그 수준이 높은 것으로 나타났다. 경제적 규제의 수준을 비교 제시한 OECD의 국가별 네트워크산업 규제지수를 살펴보면 우리나라의 물류운송산업 규제지수는 지난 40여 년 동안 점차 감소하였으나 여전히 EU, 일본, 미국 등의 국가보다 높은 수준이며 특히 철도물류에서는 가격규제와 진입규제가 상당한 것으로 파악되었다. 본 논문에서는 네트워크산업 중 하나인 물류산업의 규제 지수가 1인당 국내총생산에 미치는 효과를 고정효과 모형을 통해 분석하였다. 실증분석 결과 교통물류부문의 규제지수가 한 단위 개선될 경우 1인당 실질 GDP를 약 8.1% 증가시키는 효과가 있는 것으로 나타났다. 즉, 우리나라 물류운송산업 규제가 약 10%가량 개선될 경우 1인당 국내총생산을 2.16% 상승시키는 효과가 있을 것으로 추정되었다. 특히 이러한 개선효과는 우리나라와 같은 제조업 중심의 국가에서 경제적 규제의 개선에 대해 더욱 크게 나타날 것으로 기대되며 이를 실현하기 위해서는 물류 및 운송업 부문별로 구체적이고 신중한 규제개선 노력이 요구된다.

소비자 행동이론에 따르면 사람의 성향은 향상초점과 예방초점이라는 두 가지 조절초점 유형으로 나누어지며, 이 두 가지 성향은 다양한 영역에 있어서 소비자의 의사결정에 많은 영향을 미치는 것으로 알려져 있다. 본 연구에서는 개인화 추천에서 Cold Start 문제의 최소화 및 추천 알고리즘 성능 개선을 위하여 조절초점이론을 적용한다. 이를 위하여, 웹쇼핑 로그로부터 소비자 별 행동변수, 정보탐색활동성 지수를 추출하고 이를 활용한 소비자 조절초점성향 분류 방법을 제안한다. 본 연구는 사회과학/IT 융합 연구로서 소비자행동 이론의 시스템화 가능성을 입증하였다는 점에 있어서 의의를 지니며, 향후 다양한 분야의 이론들을 적용한 IT 서비스에 대한 연구로 확장하고자 한다.

In this study, Nuclear Power Plant (NPP) construction schedule delay risk assessment methodology is developed and the construction delay risk is assessed for turnkey international NPP projects. Three levels of delay factors were selected through literature review and discussions with nuclear industry experts. A questionnaire survey was conducted on the basis of an analytic hierarchy process (AHP) and Relative Importance Index (RII) methods and the schedule delay risk is assessed qualitatively and quantitatively by severity and frequency of occurrence of delay factors. This study assigns four main delay factors to the first level: main contractor, utility, regulatory authority, and financial and country factor. The second and the third levels are designed with 12 sub-factors and 32 sub-sub-factors, respectively. This study finds the top five most important sub-sub-factors, which are as follows: policy changes, political instability and public intervention; uncompromising regulatory criteria and licensing documents conflicting with existing regulations; robust design document review procedures; redesign due to errors in design and design changes; and worldwide shortage of qualified and experienced nuclear specific equipment manufacturers. The proposed combined AHP-RII methodology is capable of assessing delay risk effectively and efficiently. Decision makers can apply risk informed decision making to avoid unexpected construction delays of NPPs.

This study aimed to develop appropriate temperature management practices and provide scientific evidence to support the development of sell-by-date guidance for eggs. Washed and unwashed eggs were subjected to storage under six different scenarios, and both types of eggs were stored at temperatures up to 35℃ to evaluate the sell-by-date. Despite temperature fluctuations or continuous storage at 30℃ for 5 days, subsequent storage at 10℃ resulted in significantly higher Haugh unit and yolk index on day 15. These results indicate that refrigerating eggs from retail sales until consumption is effective for egg quality management, despite the exposure of up to 35℃ during distribution. In terms of sell-by-date evaluation, washed eggs retained class B quality for an additional 37 days beyond the recommended sell-by-date at 15℃, which is above the regulated storage temperature. However, unwashed eggs maintained class B quality for approximately 20 days at 30℃-35℃, emphasizing the need for sell-by-date guidelines for unwashed eggs. This study is the first to provide appropriate egg-handling practices based on the actual distribution environment in Korea.

The concept of improved performance indicators (PIs) for use in the KINS Safety Performance Indicator (SPI) program for reactor safety area is proposed in this paper. To achieve this, the recently developed PIs from the USNRC that use risk information were investigated, and a feasibility study for the application of these PIs in Korean NPPs was performed. The investigated PIs are Baseline Risk Index for Initiating Events (BRIIE), Unplanned Scrams with Complications (USwC), and Mitigating System Performance Index (MSPI). Moreover, the thresholds of the existing safety performance indicators of KINS were evaluated in consideration of the risk and regulatory response to different levels of licensee performance in the graded inspection program.
