Background: The aim of our study was to review the findings of health insurance fraud investigations and to evaluate their impacts on medical costs for target and non-target organizations. An interrupted time series study design using generalized estimation equations was used to evaluate changes in cost following fraud investigations. Methods: We used National Health Insurance claims data from 2009 to 2015, which included 20,625 medical institutions (1,614 target organizations and 19,011 non-target organizations). Outcome variable included cost change after fraud investigation. Results: Following the initiation of fraud investigations, we found statistically significant reductions in cost level for target organizations (-1.40%, p<0.001). In addition, a reduction in cost trend change per month was found for both target organizations and non-target organizations after fraud investigation (target organizations, -0.33%; non-target organizations of same region, -0.19%; non-target organizations of other regions, -0.17%). Conclusion: This study suggested that fraud investigations are associated with cost reduction in target organization. We also found similar effects of fraud investigations on health expenditure for non-target organizations located in the same region and in different regions. Our finding suggests that fraud investigations are important in controlling the growth of health expenditure. To maximize the effects of fraud investigation on the growth of health expenditure, more organizations needed to be considered as target organizations.

본 연구에서는 탐구 요소 중심의 단편적 활동 혹은 지시적인 확인 실험과 대비되는 종합적이고 포괄적인 탐구 활동으로서 실제성, 개방성, 연속성을 특징으로하는 '확장적 과학 탐구'를 개념화하고 경기도 수원에 있는 '화성'을 소재로 하여 중학교 1학년 학생들에게 적합한 확장적 과학 탐구 과제를 개발하였다. 확장적 과학 탐구의 수행 과정에서 학생들의 인지적 참여도는 어떻게 변화하는지, 확장적 과학 탐구 과제의 특징은 인지적 참여도에 어떠한 영향을 미치는지 조사하는 것이 이 연구의 목적이다. 연구 대상은 서울에 소재한 중학교의 1학년 4개 학급 학생 128명이었다. 교과서의 '힘과 운동' 단원에 제시되어 있는 2가지의 탐구 과제와 4가지의 확장적 탐구 과제를 수행하는 과정에서 각 탐구 활동이 끝난 직후 인지적 참여도에 대한 설문을 반복 시행하였고 확장적 탐구 활동이 모두 끝난 다음에는 6개의 과제에 대한 인지적 참여도를 비교해서 응답하도록 하였다. 이러한 정량적 자료와 함께 10명을 대상으로 면담을 실시하여 확장적 탐구 과제의 특정이 학생들의 인지적 참여도에 미치는 영향을 탐색하였다. 각 탐구 과제별 인지적 참여도를 분석한 결과 확장적 과학 탐구에서 교과서에 준한 탐구에 비해 탐구의 목적, 방법, 결과 등 탐구 내용과 과정 전반에 대해 이해한 정도는 증가하지 않았으나 더 능동적으로 열심히 참여했으며( p<0.01) 확장적 탐구의 후반부에서는 전반부에 비해 '이해'와 '몰두'가 모두 유의하게 증가하였다( p<0.05). 확장적 과학 탐구에서 교과서 탐구에 비해 '몰두'가 증가된 이유를 면담 결과에서 분석해 보면 확장적 과학 탐구 과제의 개방성이 주요 원인이었음을 알 수 있다. 또한 전반부에 비해 후반부에서 '이해'의 정도가 높아진 이유는 유기적으로 구성된 선행 탐구의 경험이 영향을 미친 것으로, '몰두'의 정도가 증가된 것은 탐구 과제 자체의 개방성이 증가했기 때문으로 해석할 수 있다.

This study is to survey the Japanese investigations for Korean sea during Meiji period. Meiji government was eager to develop new fishing ground to provide the marine products to their people, to offer the job for their people and to accumulate the starting capital. They found that the Korean sea was abundant in shark, sea cucumber and ear shell. These products were valuable for Chinese foods. From 1870's, Japan Navy investigated Korean sea for military purpose and subsequently for fishery. The first investigation for Korean maritime products was The Circumstances for Catching Fish in Korean Sea by Sekizawa Akikiyo in 1893. He was the most famous specialist in fishery and insisted that Japanese fishermen must go to Korean sea and catch fishes. Meiji government accepted his opinion and pushed the policy sending fishermen to Korean sea. Meiji government enlarged the investigations and backed up the activities of fisherman and the organization for fishery in Korean sea. Especially, the investigations by The Association for Korean Sea Fishery were repeated and detailed(1897~1900). The Association intervened the conflicts between Korean and Japanese fishermen. At the same time, The Association investigated the attitudes of Korean people to Japanese. The Guidelines for Fishery in Korean Sea by Kuzuu Syuzo was also very detail, especially in the kinds of fishes in Korean sea. These investigations were supported by Meiji government or organizations helped by government.

Offshore geotechnical site investigation of the seabed ground has been a key factor of the successful construction of various types of offshore structures like as sea-crossing bridges, submerged tunnels, and other marine facilities. Offshore investigations are not easy tasks because of the wave, wind, tidal ebb and flows, and others. Recent developments of offshore equipment including platforms and testing devices like as maine cone penetrator have inspired us to get more reliable characteristics of the seafloor. General information on the offshore site investigations and technical trends concerned are introduced.

It is essential to carry out appropriate site investigations for the accurate prediction of the geo-structure. However, the importance of the site investigation is often overlooked due to the time and expense constraints. In this study, several cases of geotechnical design perfromed in United States are introduced with the lessons about how the site investigations are planned, performed and applied for the actual design parameter determination. Based on the case studies presented herein, experienced geotechnical engineer should participate in site investigations from the planning stage through the final boring logs and utilize all the laboratory and field tests to have consistent input parameters for the soil constitutive models. Furthermore, it is also desired to have close relationship between construction industry and the academia to compensate their needs.

The paper presents the field investigations and seismic analyses of a historical masonry brick minaret damaged during October 23 (Erciş) and November 9 (Edremit), 2011 Van earthquakes in Turkey. Ulu Mosque Minaret located on Tebriz Kap1 Street in the city centre of Van, Turkey is selected for investigation. Two earthquakes hit the minaret within seventeen days, causing progressive damage. It was seen from the field investigations that the minaret was heavily damaged. To validate the field investigations, three dimensional finite element model of the minaret is constituted by ANSYS software using relievo drawings. Finite element model of the minaret is analyzed under the Van earthquake records to determine the seismic behavior. The displacements, maximum and minimum principal stresses and strains are obtained from the analyses and compared with field observations.

확장적 과학 탐구는 실제의 과학 활동에 보다 가까운 포괄적인 과학 탐구의 기회를 제공한다는 점에서 학교 과학교육에서 추구되어야 하며 이러한 탐구 활동을 통한 교육적 성취 중 중요한 하나가 탐구 동기라고 할 수 있다. 본 연구에서는 확장적 과학 탐구 과제의 특징인 실제성, 개방성, 연속성이 중학생의 탐구 동기에 어떠한 영향을 미치는지 구체적인 사례 분석을 통하여 탐색하였다. 탐구 동기를 조사하기 위한 설문 결과와 학생들의 과학 학습 성취 수준을 고려하여 면담 대상 학생 10명을 추출하였으며 개별 면담 결과를 기록하여 탐구 동기의 변화 사례 및 원인을 분석하였다. 확장적 탐구에 대해 정적 탐구 동기를 나타낸 학생들은 교과서 탐구가 이론의 확인에 그친다는 점에서 비판적이었으며 확장적 탐구 과제의 실제성과 개방성을 정적 탐구 동기의 주요 원인으로 인식하였다. 또 확장적 탐구에 대해 부적 탐구 동기를 보인 학생들은 교과서 중심의 학습을 강하게 선호하였으며 확장적 탐구 과제의 개방성을 부적 탐구 동기의 주요 원인으로 인식하였다. 연속성에 대해서는 대체적으로 긍정적인 반응보다는 부정적인 반응이 다소 많았으나 탐구 동기의 주요 원인으로 인식되지는 않았다.

For over 30 years, investigations of the thermohydraulic behavior of pressurized-water reactors under accident conditions have been carried out in the PKL test facility at AREVA NP in Erlangen, Germany. The PKL facility models the entire primary side and significant parts of the secondary side of a of pressurized water reactor at a height scale of 1:1. Volumes, power ratings and mass flows are scaled with a ratio of 1:145. The experimental facility consists of four primary loops with circulation pumps and steam generators (SGs) arranged symmetrically around the reactor pressure vessel (RPV). The investigations carried out encompass a very broad spectrum from accident scenario simulations with large, medium, and small breaks, over the investigation of shutdown procedures after a wide variety of accidents, to the systematic investigation of complex thermohydraulic phenomena. The PKL tests began in the mid 1970s with the support of the German Research Ministry. Since the mid 1980s, the project has also been significantly supported by the German PWR operators. Since 2001, 25 partner organizations from 15 countries have taken part in the PKL investigations with the support and mediation of the OECD/ NEA (Nuclear Energy Agency). After an overview of PKL history and a short description of the facility, this paper focuses on the investigations carried out since the beginning of the international cooperation, and shows, by means of some examples, what insights can be derived from the tests.
