There are many students in school. So school safety accidents are happened by accident. But, if teachers know and understand about school safety accidents exactly, the school safety accidents can be reduced. The conclusion of this study is as follow. First, generally teacher has a duty and responsibility to protect and care students in educational activities. And teacher has a responsibility to protect and care students only in the cases of predictability. Second, teacher must do his/her best about a duty of attention. If teacher do his/her best about a duty of attention, he(she) has not the responsibility about the accident. Third, teacher needs to have more concern student who has a controversial figure. And teacher needs to have an evidence that he/she did his/her best for the student ordinary times. Fourth, the criteria of teacher's legal or illegal punishment to students is (1) the motivation and details for punishment, (2) the methods and degree for punishment, (3) a part of body for punishment, (4) the degree of damage for punishment. Fifth, teacher need to learn the program about school safety accidents systematically.

In this article, 1'd like to analyse the principal distinctions between the duty of disclosure and warranty which are based on the same legal principles, utmost good faith(uberrima fides). Although the duty of disclosure and warranty have a same legal principle to protect insurance contract, they have several difference in appliance actually. Through these comparative analysis, 1 want to reveal the character of warranty which is unfamiliar to us under our commercial law. Warranty has some peculiarity, these are (a)A warranty does not have to be material to the risk, (b)A warranty must be exactly complied with, (c)It is impossible to defence for a breach of warranty, the breach of warranty is irremediable, and A casual connection between breach and loss needs not be shone, (d)A breach of a warranty may be waived by insurer. Sometimes in Korea like those stringent principles of warranty make Korean's small fishing or shipping company suffer from difficult because of insistence of discharge from liability by insurer. So I expect that all of them acknowledge the character of warranty and can make them protect their insurance money by themselves.

In wireless sensor networks (WSNs) duty cycling has been an imperative choice to reduce idle listening but it introduces sleep delay. Thus, the conventional WSN medium access control protocols are bound by the energy-latency tradeoff. To break through the tradeoff, we propose a radio wave sensor called radio frequency (RF) wakeup sensor that is dedicated to sense the presence of a RF signal. The distinctive feature of our design is that the RF wakeup sensor can provide the same sensitivity but with two orders of magnitude less energy than the underlying RF module. With RF wakeup sensor a sensor node no longer requires duty cycling. Instead, it can maintain a sleep state until its RF wakeup sensor detects a communication signal. According to our analysis, the response time of the RF wakeup sensor is much shorter than the minimum transmission time of a typical communication module. Therefore, we apply duty cycling to the RF wakeup sensor to further reduce the energy consumption without performance degradation. We evaluate the circuital characteristics of our RF wakeup sensor design by using Advanced Design System 2009 simulator. The results show that RF wakeup sensor allows a sensor node to completely turn off their communication module by performing the around-the-clock carrier sensing while it consumes only 0.07% energy of an idle communication module.

The traditional regulatory approach to managing pilots fatigue has been to prescribe limits on maximum daily, monthly, and yearly flight and duty hours, and require minimum breaks within and between duty periods. This approach comes from a long history of limits on working hours dating back to the industrial revolution. So, the Council of ICAO recently adopted International Commercial Air Transport regarding the development and implementation of fatigue risk management systems(FRMS). The FRMS can provide better safety outcomes than current prescriptive flight and duty regulations while allowing greater operational flexibility. This study aim to analyzing relative importance of pilots' fatigue factors in order to minimize pilots' fatigue-related safety risks. More researches regarding monitoring and managing fatigue, based upon scientific principles, are required in the future.

The purpose of this study was analyzed the factors of influencing toward attitude to death with dignity to hospice volunteers. The data was collected for 21 days from 14 March to 3 April 2010. Among a total of 220 cases of the questionaries, only 195 cases were used. To data were analyzed by factor analysis, independent t-test, one-way anova and logistic regression using PASW statistics 18.0. The results were as follows; The attitudes towards death with dignity according to general characteristics was high in those with will to agreed to the passive euthanasia than those opposite to the attitude factors, namely, acceptive, the right to decide, negative, and dereliction of duty attitude factors. Significant variables for effects of death with dignity were gender, acceptive attitude factor and dereliction of duty attitude factors. Given that main provider of human organs is the brain-dead and we don't have enough organ donation, death with dignity should be linked with activating policy of organ donation, while solving donation shortage problem. This way, constructing social implementation and sharing consciousness on organ donation, would be diluting the bio-ethic controversies.

Purpose - We assess the trade remedies rules in a host of Korea's FTAs to explore the trade policies for the effective implementation of FTA trade remedies rules. Also we develop the strategies of the future FTA negotiations of trade remedies rules. Design/methodology - After we review the key features of FTA trade remedies rules, we examine whether the rules are WTO-consistent or not. Next, we touch upon the WTO-plus characteristics of some provisions. Our main methodology is to compare the trade remedies rules in the numerous Korea's FTAs. Another methodology is to link those rules to the relevant WTO agreements and WTO dispute cases with a view to drawing lessons for trade policies and FTA negotiations. Findings - We find that most of the trade remedies rules are WTO-consistent. Moreover, we find that notification and consultation requirment, mandatory lesser duty rule, explicit prohibition of zeroing method, and public interest clause are WTO-plus. We also find that there are limitiations in the application of some global safeguard exclusion rules because of their non-mandatory nature. Originality/value - While most of previous studies focus mainly on the unique aspects of specific FTAs, our study analyzes comprehensively the trade remedies rules in the various Korea's FTAs. Based on the comprehensive analysis, we figure out the areas to be clarified and improved for the effective implementation of FTAs and the strategies for the future FTA trade remedies negotiations. As a consequence, our paper is expected to contribute to the academic research on FTA policies as well as the national economy.
