Background: This study aimed to examine whether cases of punishing false claimants threat general physicians to check their medical cost claims with care to avoid being suspected, and identify empirically general deterrence effects of the on-site investigation system in the Korean National Health Insurance. Methods: 800 clinics were selected among a total of 15,443 clinics that had no experience of on-site investigation until June 2007 using a stratified proportional systematic sampling method. We conducted logistic multiple regression to examine the association between factors related to provider's perception of on-site investigation and high level of perceived deterrence referring to fear of punishment after adjusting provider's service experiences and general characteristics. Results: The probability of high perceived deterrence was higher 1.7 times (CI: 1.13-2.56), 2.73 times (CI: 1.68-4.45) each among clinics exchanging the information once or more per year or once or more for 2-3 months than among clinics no exchanging the information about on-site investigation. Also, the probability of high perceived deterrence was higher 2.27 times (CI: 1.28-4.45) among clinics that knows more than 3 health care institutions having experienced an on-site investigation than among clinics knowing no case. Conclusion: A clinic knowing more punishment cases by onsite investigation and exchanging more frequently information about on-site investigation is likely to present high perceived deterrence. This result will provide important information to enlarge preventive effects of on-site investigation on fraud and abuse claims.

To perform an effective screening for toxic materials of forensic interest detected in high profile criminal case in biological and environmental samples, we tried to construct a searchable computerized database using HPTLC(High Performance Thin Layer Chromatography) and GC/MS. Retardation factor($R_f$) values and UV spectral data of HPTLC were investigated for 160 pesticides, 34 chemicals and 39 explosives of standard grade. The data were compiled in a library. We also analyzed 112 pesticides, 31 chemicals and 17 explosives and 57 volatile organic compounds(VOCs) by GC/MS. The data for RT and characteristic mass ions were also compiled in a library.

The extended science investigations, comprehensive investigations contrasted with exercises of process skill components and cookbook style experiments, should be pursued for giving opportunity of more authentic science activity. The characteristics of the extended investigation tasks were emerged from critical argument on school practical work. And one of important educational objectives in students' investigations is to achieve motivation for investigation. The purpose of this study is to explore how the characteristics of the extended investigation tasks, that is practical context, openness and continuity, affect middle school students' motivation for investigation. On the basis of questionnaire results and students' school science achievement, ten students were interviewed to see the change of motivation for investigation and its causes while they perform two textbook investigations and four extended investigation tasks. Among the interviewees, the students who showed positive motivation for the extended investigations were critical about textbook experiments as they are just confirmations of theories and perceived practical context and openness as the main causes of their positive motivation. The students who showed negative motivation for extended investigations preferred textbook experiments as there was enough guidance from teacher and textbook-centered learning. They recognized the openness of the tasks as a main reason of their negative motivation for investigation. Some students showed negative responses about continuity of the extended investigation tasks but continuity was not recognized as a main cause for their motivation for investigation.

The marine safety investigation inquires and concludes the facts and causes of the marine casualties and incidents with the objective of preventing similar roses in the future. Thus, IMO and most states adopt and revise marine safety related conventions and national laws based on the results of marine safety investigation. In particular, IMO recently adopts mandatory IMO Casualty Investigation Code to identify the precise cause of rose with states' cooperation, to report the result of investigation, and to establish new international safety standard helping prevention of similar cases based on the report. The Judgement of the Korean Maritime Safety Tribunal system based on the 'Act on the investigation of and inquiry into marine accidents' is used for the purpose of marine safety investigation in Korea to prove cause of marine accident and to improve marine safety. Therefore, this study examines the Code and compares the Code with the Act to reflect the contents of provisions in the Code into the Act. The study would also be the basic references in relation to revising of marine safety investigation system in Korea Specially, the contents in relation to the independence of investigation authority and mandatory counselling system, and guarantee of seafarers human rights to ensure fairness of investigation would be included.

The on-going pre-environmental investigation at present is performed by separate numerical analysis of each provision which makes integrated pre-environmental investigation is difficult. The application of numerical data is insufficient, which results to the deterioration of environmental investigation result's objectivity. A lot of time and money is required for the investigation. In this study, the spacial analysis function of GIS was applied on the 8 pre-environmental investigation factors. Pre-environmental investigation GIS DMS(Decision Making System) was constructed to make integrated investigation possible through the use of investigation results for each factor. Through the use of the developed pre-environmental investigation GIS DMS and the pre-constructed GIS data, the objectivity of environmental investigation is sufficient and time and cost are reduced. Therefore, this system can be used for pre-environmental investigation during route selection in the initial stages of road construction. Through the numerical and visual data obtained from the system developed in this paper, it is easier to gain the approval of the public. Furthermore, environmental problems due to road construction can be investigated with less time and money during the initial stages of road construction.

ICAO Universal Safety Oversight Audit Programme is a comprehensive evaluation for aviation safety matters, including aircraft operation, licensing and aircraft incident/accident investigation. As this programme is measures aviation safety level of States, there is a need to meet international standards, especially in the field of aircraft incident/accident investigation. This research discusses points required to satisfy international standards, which are independence and autonomy of an accident investigation board, the lack of the enough number of investigators and efficient management of those personnel, the effective composition and use of an investigation report, an accident investigation itself to build big data and the creation of a cooperation system among States. This paper suggests various opinions in order to enhance aviation safety especially through aircraft accident investigations, using case studies from the US, UK and Japan.

Cut slope and facility of management investigation is the protection of humans and properties. it is very important the prevention of disaster facility and the damage of the slope protection facility. It is very difficult to forecast slope stability, disaster possibility and collapse. It will be able to minimize the damage which it prepare against slope facility and cut slope of deformable investigation and collapse and the disaster. therefore those deformable investigation is important. Investigations execute upheaval, crack, sliding for slope and cut slope reinforcement. Investigation executes forecast in place where the construction problem, the effect which the damage in road traffic or the contiguity facility.
