The paper presents a method to detect dissolve shots of video scene change detections in an MPEG compressed domain. The proposed algorithm uses color-R DCT coefficients of Ⅰ, P-frames for a fast operation and accurate detection and a minimum decoding process in MPEG sequences. The paper presents a method to detect dissolve shot for three-dimensional visualization and analysis of Image in order to recognize easily in computer as a human detects accurately shots of scene change. First, Color-R DCT coefficients for 8*8 units are obtained and the features are summed in a row. Second, Four-step analysis are Performed for differences of the sum in the frame sequences. The experimental results showed that the algorithm has better detection performance, such as precision and recall rate, than the existing method using an average for all DC image by performing four step analysis. The algorithm has the advantage of speed, simplicity and accuracy. In addition. it requires less amount of storage.

By using thermal decomposition method, the preliminary experiments for recovery of metallic Ga from GaAs scraps produced in the manufacturing of compound semiconductors were carried out in laboratory(200 g/batch) scales. From these results, decomposition appratus with packed tower was constructed in commercial scale(30 kg/batch). The decomposition rate of GaAs increased with raising decomposition temperature, but the yield of Ga decreased over 1000$^{\circ}C. As a result, the optimum decomposition temperature was 1000~1050$^{\circ}C when the pressure of decomposition reactor was 2~2.5${\times}10^{-2} mmHg, and the yield of Ga was about 89 wt.%. The commercial decomposition apparatus was designed with packed tower because the partial pressure of As in vapor state was not reduced even if the temperature of As vapor was decreased. The recovery yield of Ga from GaAs scraps in large scale experiment showed 99%.

This study aims to examine the continuity of national education between prewar and postwar Japan in the context of nationalism and citizenship education by considering the direction and process of educational reform which has been a turning point in Japanese education policy. It explores the limitations of educational reform at the normative level and institutional and procedural level. Meiji Japan needed to form a united group to support modernization while also cultivating obedient people who supported the emperor, and the modern education system played a major role in achieving this task. After Japan's defeat in World War II, the nation sought to change the framework of authoritarian nationalism inherent in Japanese traditional through educational reforms and achieve the goals of democratization and non-militarization. The postwar educational reform has transformed the educational structure, but democracy and peace orientation have not been rooted internally. Under the backdrop of the Cold War, the education returned to the inverse.

2015년은 국제사회 거버넌스 및 정책 패러다임에 있어 전환점(tipping point)을 맞는다. 2000년 국제사회가 인류의 빈곤 퇴치라는 삶에 가장 절대적인 개발목표로 2015년까지 달성해야 할 빈곤, 의료, 교육 등 사회 환경 현안에서 해결해야 할 단순명료한 목표를 제시하였다. 그리고 2015년 9월 UN 지속가능 세계정상 회의(World Summit on Sustainable Development, WSSD)에서는 지속가능개발목표(Sustainable Development Goals, SDGs)를 채택하여 2030년까지 전 세계가 경제성장, 기후 변화 등 경제적, 사회적, 환경적 측면을 통합적으로 고려하여 지속가능한 인간정주환경을 조성하자는데 합의를 마쳤다. 17개의 지속가능개발목표와 부속적으로 169개의 타겟이 설정되었으며, SDGs 안에서는 MDGs의 기조를 유지하면서, 인간의 권리 구현과 성평등, 여성과 어린이의 권리 신장 등을 포함하고 있으며, 기후변화와 예측이 불확실한 다양한 자연재난, 특히 물과 물 관련 재해가 빈곤 경감, 기후변화 대응, 인간정주의 모든 삶의 영역에 연계요소로 녹아 있다. 기후변화 적응과 물 안보, 특히 위기관리의 맥락이 내재되어 있는 2030년을 목표로 하는 국제사회의 Post-2015 개발의제에서 물 분야는 무엇보다 중요한 관심 분야로 부각이 되어 있다. 17개의 지속가능개발목표에서 SDG6을 "모두를 위한 물과 위생의 지속가능한 관리와 이용(Ensure availability and sustainable management of water and sanitation for all)"으로 하고 수자원관리 및 물과 위생 분야의 중요성을 전세계가 공감하고 함께 해결해 나가야 함을 강조하였다. 그러나 실질적으로는 물을 직접적으로 언급한 6번째 목표뿐만 아니라, 빈곤의 근절(SDG1), 기아근절과 지속가능한 농업의 증진(SDG2)을 비롯한 다양한 목표들에서 물 분야가 직접?간접적으로 연계 되어 있으며, 특히 기후변화의 영향으로 더욱 심각해진 물관련 재해로부터 리질리언스 확보 등, 지속가능개발목표의 전반적인 기조에서 물안보 확보를 읽을 수 있다. 물 분야에서 지속가능개발목표의 이행을 위한 노력은 국제사회의 물 문제 해결에 공동으로 대응하기 위한 글로벌 동반 성장 지원체계를 구축하기 위한 초석이 될 것이다.

After the joining in the WTO of China, the container throughputs have begun to increase notably and Continuous developments of China ports are influencing operation and policy of Korea ports. At this point Pyeongtaek Dangjin port which has potency as China trading port confronts with turning point of port development as new port. To this, correct need grasping of North China shippers is important strategic element of PyeongTaek Dangjin Port activation. In this study, there is purpose to present Pyeongtaek Port's activation strategy by grasping customer needs executing questionnaire to China local company about Pyeongtaek Dangjin Port. As a research result, Pyeongtaek Dangjin Port possesses high geographical strength but has problems like development delay, tribe of various route, absence of marketing strategy. To solve this problem, this paper proposes expansion of port and logistics physical distribution equipment, improvement of services, foundation of joint logistics center, establishment of marketing organization etc. Namely, it may overcome only new port's limitation though develop to port of cargo creation style that is not simple cargo dependence style port.

In order to combat the spread of COVID-19, on January 30, 2020, the World Health Organization declared that the spread of COVID-19 has met the criteria of a "Public Health Emergency of International Concern" under Article 1 of the International Health Regulations(2005) and proposed a variety of preliminary recommendations to fight against the pandemic accordingly. All of a sudden, people are ordered to wear face-masks in public-which is forbidden for different reasons in many jurisdictions. Of course, the legal world was hit by the virus as well. Needless to mention that where economic and social life will change so drastically, the legal world will change(ex. virtual hearing) as well. Most probably, it will not ever be the same after COVID-19. And where the whole legal world will change, it is easy to state the obvious, namely that COVID-19 has and will have an impact on international arbitration as well. This paper will describe how international arbitration is dealing with this new challenge.

In this paper, we estimate a model that incorporates key features of business cycles, co-movement among economic variables and switching between regimes of expansion and recession, to aggregate quarterly data for the NAFTA region. Two common factors reflecting the permanent and transitory components of the business cycle in the region, along with the turning points from one regime to the other, were extracted from the data by using the Kalman filter and maximum likelihood estimation approach of Kim (1994). Estimation results confirm that a typical aspect of business cycles are also observed (i.e., recessions are steeper and shorter than recoveries) in the region, and that both co-movement and that regime switching are found to be important features of the business cycle. The two common factors produce sensible representations of the trend and cycle, and the estimated turning points are in line with independently determined chronologies. It also turns out that the degree of synchronization between the NAFTA region and Korea, has significantly increased since the entry into force of the NAFTA.

Accurate forecasting of volatility is of considerable interest in financial volatility research, particularly in regard to portfolio allocation, option pricing and risk management because volatility is equal to market risk. So, we attempted to delineate a model with good ability to forecast and identified stylized features of volatility, with a focus on volatility persistence or long memory in the Australian futures market. In this context, we assessed the long-memory property in the volatility of index futures contracts using three conditional volatility models, namely the GARCH, IGARCH and FIGARCH models. We found that the FIGARCH model better captures the long-memory property than do the GARCH and IGARCH models. Additionally, we found that the FIGARCH model provides superior performance in one-day-ahead volatility forecasts. As discussed in this paper, the FIGARCH model should prove a useful technique in forecasting the long-memory volatility in the Australian index futures market.

This study investigates the issues in relation to the introduction of the fund-based Korean occupational pension, examining the development plans in the members' perspective. The strong drive from Korean government to introduce the fund-based governance seems to be a sort of strategy to expand coverage in occupational pension. It is not logical that the introduction of the fund-based scheme is likely to cause increase in earning rate and, what is more important is to set the conditions to implement the active investment decision. Also, because the introduction of the fund-based scheme may increase possibility of insolvency, it is necessary to strengthen beneficiary protection or funding rule but, in the short term, it is better to focus on funding rule rather than protection scheme. The introduction of the fund-based scheme suggests the direction that members can actively participate in occupational pension, which means that it is possible to operate occupational pension in the direction of intent of the system.
