Using the changes in structural primary budget balance and GDP gap in South Korea, I examine whether the discretionary fiscal policies have been effectively used to mitigate business fluctuations for the last 30 years in Korea. I investigate the stances of monetary policy and the exchange rate changes in order to consider the interconnectedness of fiscal and monetary policies as stabilization policy tools based on the historical observation that Korea experienced the growth-oriented policy regime and has been very susceptible to foreign shocks. My results show that the tendency of expansionary fiscal policies was observed when the effective real exchange rate was rising. During the boom, the expansionary fiscal policies were frequently adopted with the increases in interest rate. Although this tendency has been weakened since 2000, the inappropriate combinations of fiscal and monetary policies were still observed. These results show that implementation of countercyclical fiscal polices should be decided with careful consideration of monetary policy stance as well as the characteristics of external shocks.

In the 21 century the number of participants in folk culture tourism has increased significantly and its popularity has grown rapidly. Folk culture tourism does not only represent history but encompasses all aspects of human history. World folk culture comprises on one part the tangible heritage, that which is unmovable, such as monuments, buildings, archaeological sites, and historic complexes which embody cultural significant traditions. World folk culture also includes the intangible movable heritage such as intellectual heritage, including artworks of archaeological importance and those representing skills. However, to obtain a tourist product value, intangible heritage needs to be transformed into a tangible one, through their own symbol and meaning, so that it can reflect its own unique cultural character. In particular the world folk culture is one of the most important tourism resources. The purpose of this research is to verify what factors change a folk culture into a tourism product and, how to create tourist products through world folk culture items in a way that contributes to the Korean tourism industry. To develop this theory of tourism merchandising, world folk culture has been analyzed strategic approach. The development into a world folk culture tourism product has following process: First, recognition and understanding of the meaning and value of the world folk culture items. Second, value creation as a tourist product through cultural resources. Third, creation of traditional cultural image, uniqueness and theme on tangible and intangible resources, Finally, application of Korean traditional concept to the tourist facilities.

불완전한 환경세 사용에 따른 잠재적 후생 손실

홍인기 ( In Kee Hong ) 한국환경경제학회·한국자원경제학회(구 한국환경경제학회) 2015 자원·환경경제연구 Vol.24 No.1

지난 30년간 환경세나 배출권과 같은 경제적 정책도구들이 환경정책의 영역에서 꾸준히 각광을 받아왔다. 경제적 환경정책도구들은 저마다 특성이 다르고, 각국 정책당국이 직면한 환경문제의 구조적 제도적 배경이 상이하기 때문에, 교과서적인 의미에서의 피구세(배출세)와 같은 정책도구는 널리 사용되지 못하는 상황이다. 오히려 산출물이나 소비 등에 부과하는 환경관련 조세를 부과함으로써 피구세 사용에 수반되는 한계와 어려움을 회피하려는 경향이 강하다. 즉, 피구세(배출세)를 사용하지 못함으로써 이미 상당한 후생손실을 감내할 수밖에 없는 것이다. 특히 개발도상국들에서는 구조적 제도적 제약들이 선진국에 비해서 더 많고 크기 때문에, 제대로 된 피구세(배출세)를 사용하지 못함에 따라 입는 후생손실이 훨씬 커질 수 있다. 본 논문에서는 이 점을 보여주기 위해서, 이론적인 일반균형모형을 통해 노동에 대한 과세가 존재하는 차선의 상황에서, 피구세 및 산출세 수준을 최선과 차선의 경우에 계산하고, 각종 구조적 제도적 제약을 모형 내의 파라미터로 표현한 사회후생 수식을 통해 도출해낸다. 그리고 피구세에 대한 불완전하지만 현실적인 대안으로 산출세를 이용하여 환경문제를 해결하려 하는 경우, 후생증진의 차이가 얼마나 벌어지는지 살펴본다. 또한 미국과 중국의 예를 들어, 환경 차원에서 불완전한 산출세를 사용함으로써 겪는 후생손실이 개도국의 경우 산업국가에 비해서 무려 6배나 벌어질 수 있음을 시뮬레이션을 통해 보여준다. In environmental policy areas, a greater use of economic instruments (EIs) has recently been observed in many countries. However, EIs are heterogeneous policy tools. The textbook case of a Pigouvian tax is far from widely used, mainly due to the information requirements and other structural and institutional constraints. The successful implementation of EIs might heavily depend on pre-existing structural and institutional conditions. Moreover, these institutional conditions are particularly unfavorable in developing countries. Using a simple analytical general equilibrium model, this paper examines how these constraints affect the welfare gain from the introduction of environmental taxes in developing countries. First, this paper solves for the second-best optimal Pigouvian tax and output tax in the presence of a distortionary tax on market use of labor. The result confirms that an environmental output tax achieves a socially-efficient level of emissions in the least-cost manner only if the nature of the linkage between the tax base and the environmental damage is fixed. Second, incorporating structural and institutional constraints into the model through a set of parameter values from China and the US, this paper calculates the net welfare effects of either using the ideal Pigouvian tax or instead using an output tax. The numerical simulation results show that the net welfare gain from the use of an ideal Pigouvian tax could be more than six times larger than that of an output tax in developing countries. On the other hand, the welfare gain is only 50 percent in developed countries. This means that the potential welfare disadvantage from using output taxes instead emissions tax for environmental purposes could be much greater in the case of developing countries.

다발성 경화증 질환의 자기공명 T2 강조영상에서 단면 두께 변화에 따른 잡음 평가

Magnetic resonance imaging(MRI) uses strong magnetic field to image the cross-section of human body and has excellent image quality with no risk of radiation exposure. Because of above-mentioned advantages, MRI has been widely used in clinical fields. However, the noise generated in MRI degrades the quality of medical images and has a negative effect on quick and accurate diagnosis. In particular, examining a object with a detailed structure such as brain, image quality degradation becomes a problem for diagnosis. Therefore, in this study, we acquired T2 weighted 3D data of multiple sclerosis disease using BrainWeb simulation program, and used quantitative evaluation factors to find appropriate slice thickness among 1, 3, 5, and 7 mm. Coefficient of variation and contrast to noise ratio were calculated to evaluate the noise level, and root mean square error and peak signal to noise ratio were used to evaluate the similarity with the reference image. As a result, the noise level decreased as the slice thickness increased, while the similarity decreased after 5 mm. In conclusion, as the slice thickness increases, the noise is reduced and the image quality is improved. However, since the edge signal is lost due to overlapped signal, it is considered that selecting appropriate slice thickness is necessary.

Purpose: Diabetes mellitus refers to one of several risk factors for cardiovascular diseases, renal failure and so on. Medical treatments of T2DM cannot suggest a perfect cure. But gastric bypass resulting in the exclusion of the duodenum and proximal jejunum has been shown to improve or resolve T2DM. The goal of this study is to evaluate the effect of duodenojejunal bypass for T2DM patients below BMI 25 ㎏/㎡ in early postoperative period. Methods: Duodenojejunal bypass was performed on 25 patients at Inha University Hospital from July 2009 to April 2010. We compared 75 g OGTT, insulin, C peptide to those 7 days postoperative. The definitions for improvement are serum glucose level below 200 ㎎/㎗ of 75 g OGTT at 120 min or below 200 ㎎/㎗ at every other time in spite of over 200 ㎎/㎗ at 120 min. Results: A total of 25 patients (15 men and 10 women) were included. Median value BMI was 23.17 ㎏/㎡ and the mean duration of T2DM was 8.3 years. There was a significant decrease of postoperative 75 g OGTT levels from 176, 268, 345, 373, 371 ㎎/㎗ to 125, 170, 200, 225 and 241 ㎎/㎗, respectively (P<0.001). Only patients’ age was an independent factor resolution of T2DM based on this study. Conclusion: Duodenojejunal bypass could be one viable treatment modality for improving or resolving of T2DM although these are early results. This study has preliminary meanings only and the results of longer follow-up and a larger number of patients are necessary, by which we should be able to determine the effect and indications for surgical treatment of T2DM.
