This study analyzes the socio-economical contexts of Japan's Karaoke inflow in Busan of the 1980s, and examines the relationship between Karaoke culture of the 1980s and 'Noraebang' culture of the early 1990s in Busan from the perspective of the SCOT(social construction of technology) theory. By the end of 1970s, Japan's Karaoke was introduced under the contexts of structural transformations of a geisha tourism in the East Asian regions. Karaoke culture in Busan of the 1970s and 1980s has formulated social recognitions of the novelty of Noraebang culture in the 1990s, although it has done so through the ways of misunderstandings and Nationalism.

최근 하천관리 정책은 단편적인 홍수방어뿐만 아니라 맑은 물을 안전하게 확보하고 건강한 생태계가 유지되는 하천으로 관리하는 방향에 주안점을 두고 있다. 그러나 치수 목적의 하천관리 기술에 비하여 하천환경관리를 위한 기술은 요소기술 개발 및 적용으로 산재되어 있어, 체계가 정립되지 못하고 실무 적용에서도 활용에 한계가 있는 실정이다. 따라서 본 연구에서는 치수, 이수, 하천환경 목적의 다차원 하천관리를 위하여 하천복원의 기술적 체계를 기술수준의 정도를 기준으로 단계별로 정립하였다. 첫 단계는 수문특성, 수리특성, 하상변동/유사특성, 생물/화학특성의 분석이다. 이 단계에서는 각 특성의 현황과 하천복원 방법에 따른 물리특성 변화를 분석하는 것이다. 다음 단계는 하천복원에 따른 정량적인 기대효과 분석이다. 수위저감 및 안정하도 확보, 수질개선, 생물서식처 효과분석 등이 수행된다. 마지막 단계는 하천복원 등의 관리계획에 의한 기대효과 전망이다. 사회경제적 가치, 생물종 다양성 확대가치 등이 분석항목에 포함된다. 각 단계에서는 계량 가능한 지표를 설정하여 계획의 성과를 비교한다. 제안된 다차원 하천복원 기술적 프레임웍을 통해 하천사업에 따른 물리, 생물, 사회, 경제 등 다양한 분야의 구조를 통합한 방법론을 제시함으로써 하도개선 위주의 획일적인 하천복원사업에 변화를 주고, 더 나아가 하천공간 복원 등 적극적인 하천복원사업이 활성화되길 기대한다.

습지 생태계는 탄소저장고, 대기 온·습도 조절 등의 기능을 수행하는 만큼 면밀한 관리가 요구된다. 습지의 규모와 생태계는 밀접한 연관성을 가지므로 그 규모를 우선적으로 파악할 필요가 있으며, 이를 위해 지표면의 상태를 산지, 습지, 수역 등의 항목으로 구분한 토지피복지도가 고려될 수 있다. 현재, 환경부에서 운영 중인 환경공간정보서비스(https://egis.me.go.kr/)에서는 각각 30 m, 5 m, 1 m의 공간 해상도와 7, 22, 41가지 분류 항목을 갖는 대분류, 중분류, 세분류로 구분된 토지피복지도를 제공하며 이러한 자료들은 모두 1년 이상의 시간 해상도를 갖는다. 습지의 경우, 계절에 따른 환경 변화로 인한 규모의 변동성이 크게 나타날 수 있기 때문에 1년 이하의 시간 해상도를 갖는 고품질 토지피복 분류 정보가 요구된다. 따라서 본 연구에서는 기존 자료의 낮은 시간 해상도 보완을 목표로, 1개월과 30 m의 시·공간 해상도를 갖는 토지피복지도를 구축하기 위한 방법론을 제안하고자 한다. 이를 위해 Landsat-8 등과 같은 다양한 인공위성 자료를 수집하고, Support Vector Machine 등과 같은 머신러닝 기법을 적용하였다. 최종적으로 습지보전법에서 지정한 습지보호지역 중 내륙습지 26개소를 대상으로, 본 연구로부터 산출된 토지피복지도를 기존 환경공간정보서비스 내 대분류 토지피복지도와 비교·평가하였다.

This paper aims to apply the convergence theory into the minimum income guarantee which forms the moral foundation of the welfare state. The research question of this paper is if the level of minimum income guarantee among EU member states (EU-15) gradually converging into a certain level. For this purpose, Chapter 2 describes the convergence and diversion of welfare states since the Second World War, and chapter 3 explains the historical development of the EU social policies since the Rome Treaty (1957). Chapter 4, which is the main body of this paper, analyzes if the level of minimum income guarantees of EU member states is converging by the coefficient of variation analysis and regression analysis. However, converging trend of the level of basic income guarantee among EU member states has not been proved. In other words, social policy arena still remains strongly in the realm of national sovereign states, irrespective of growing pressure from the supra-national governing body like the EU. It is in line with the Abram de Swaan's argument that "welfare states is nation states" (1994: 110).

This study aims to classify broadscale anti-religious movements in Korea based on critical public sentiment and analyze the meanings of these movements. To carry out the research, global religious changes that have occurred in modern times were closely looked into first. The world religions have had an influence on the world's religious awareness. As a result, they intend to acquire universality on their own individual grounds while keeping consistency with the past. This phenomenon used to appear to retain the identity, recreate tradition, transform itself to fit in the present times, pursue innovation, or even become overshadowed by other forms of thought such as when religions have collided with nationalism. How does Korean society perceive the changes that emerged in world religions? In general, the circumstances that Korea faces in this era tend to manifest themselves via the Internet, multimedia, and Youtube wherein they sound off on religion and this includes criticism of Christianity, demand for reformation, attack on minor religions, pro-reform academic circles and media, and the propagation of anti-theism. Criticism of religion is interpreted as an anti-religious movement. The secularism and anti-theism brought up by some Western scholars and critical theories of religion from scientific or historical perspectives are being spread through bookstores. Christianity is prone to reflecting on itself and trying to emphasizing a meta-religious spirituality. This in short, characterizes anti-religious movements in Korea. Indeed, criticism against particular religions has also emerged in the past. However, anti-religious movements that have recently come into existence in Korea are in some regards unprecedented when compared to that of the past in terms of their patterns and context. Especially, the active anti-Christianity movement in general is definitely a new phenomenon. This research mainly focused on Christianity, but on-going anti-religious movements will be a major topic for further research that aims to understand the religious changes unfolding in Korea.

This study quantified the data by applying the EDA techniques considering the data structure, and the results were then used for the frequency analysis. Although traditional methods based on the method of moments provide very sensitive statistics to the extreme values, the EDA techniques have an advantage of providing very stable statistics with their small variation. For the application of the EDA techniques to the frequency analysis, it is necessary to normalization transform and inverse-transform to conserve the skewness of the raw data. That is, it is necessary to transform the raw data to make the data follow the normal distribution, to estimate the statistics by applying the EDA techniques, and then finally to inverse-transform the statistics of transformed data. These statistics decided are then applied for the frequency analysis with a given probability density function. This study analyzed the annual maxima one hour rainfall data at Seoul and Pohang stations. As a result, it was found that more stable rainfall quantiles, which were also less sensitive to extreme values, could be estimated by applying the EDA techniques. This methodology may be effectively used for the frequency analysis of rainfall at stations with especially high annual variations of rainfall due to climate change, etc.

This study gropes for historical geographic approach to regional research in view of new regional geography. A geographical methodology in regional geography pursues the dialectics of concrete totalities. Regional researches think that social processes interact with the uniqueness of regional characteristics and that region is a historical unit which changes dynamically. Time in regional changes is understood in terms of a dialectics of continuity and break. Transition from feudalism to capitalism is the important period which is captured continuity and break simultaneously. Research objects in this research are money, market and city. Money symbolizes transition to capitalism, and market and city have the importance in transition from feudalism to capitalism In Korea, historical geographic approach to money, market and city both in the era of opening ports and in the Japanese colonial times in Korea are important objects in regional geography. Colonial urban research in view of money and market from the era of opening ports to the Japanese colonial times in Korea is a theme which includes a dialectic of concrete totalities in historical geographic approach in regional geography.

Objectives: Angiotensin-converting enzyme (ACE) gene polymorphism has been reported to be associated with depression and therapeutic outcome in depression. The purpose of this study was to determine whether ACE gene polymorphism is associated with seasonal variation in mood and behavior in a young Korean college student sample. Methods: 297 young Korean medical students were recruited in this study. All subjects were free of major medical and psychiatric problems. They were genotyped for the ACE gene polymorphism and evaluated the seasonal variation in mood and behavior by the Seasonality Pattern Assessment Questionnaire (SPAQ). Results: Global Seasonality Score (GSS) of SPAQ between three genotypes were not different. However, comparison of the group that showed seasonality of mood and behavior during winter with the group that did not showed seasonality indicated significant difference in genotype distribution ($x^2=6.79$, p=0.034). The D allele non-carrier (ll genotype) frequency was significantly higher in winter seasonality group than non-seasonality group ($x^2=6.59$, p=0.010；odds ratio [OR]=2.27, 95% confidence interval [CI] 1.20-4.28). Conclusion: These results suggest that the ACE gene polymorphism is related to winter-type seasonality in a Korean population.

Recently, as climate change caused by greenhouse gases is intensifying, the international community has committed to reduce greenhouse gas emissions. The purpose of this study is to present the methodology and major considerations for investment judgment. Two actual cases of overseas projects were selected as study subjects. As an analysis method, the major risk factors were defined as a probability distribution, and the NPV was stochastically estimated using the Monte Carlo simulation method. In addition, assuming a policy change, the range of NPV change was analyzed. As a result, the average NPV of project A was lowered by 19%, and the probability of showing a negative NPV was 12.2%. The average value of project B was lowered by 12.5%. Considering the policy change, project A can obtain economic benefits only when it obtains 72.9% or more of the total amount of carbon credits generated, and project B is economically feasible when it acquires 49.5% or more. As a result, the average value of project A is lower than the net present value under basic assumptions, so caution is needed in investment decisions depending on changes in major risk factors. Additionally, considering policy changes, the carbon credit distribution ratio should be differentially applied depending on the project size, and this was presented as a specific figure.
