Affected by external factors, errors in time series data collected by sensors are common. Using the traditional method of constraining the speed change rate to clean the errors can get good performance. However, they are only limited to the data of stable changing speed because of fixed constraint rules. Actually, data with uneven changing speed is common in practice. To solve this problem, an online cleaning algorithm for time series data based on dynamic speed change rate constraints is proposed in this paper. Since time series data usually changes periodically, we use the extreme learning machine to learn the law of speed changes from past data and predict the speed ranges that change over time to detect the data. In order to realize online data repair, a dual-window mechanism is proposed to transform the global optimal into the local optimal, and the traditional minimum change principle and median theorem are applied in the selection of the repair strategy. Aiming at the problem that the repair method based on the minimum change principle cannot correct consecutive abnormal points, through quantitative analysis, it is believed that the repair strategy should be the boundary of the repair candidate set. The experimental results obtained on the dataset show that the method proposed in this paper can get a better repair effect.

The purpose of this study is to review the laws on foreign investment and the changed licensing procedures in Laos and to provide the data for basic understanding of foreign forestation investment in Laos. The conclusions are as follows. The Laos government has been consistently trying to promote foreign investment. In particular, in 2004, the "Law on the Promotion of Foreign Investment" was legislated. In 2009, the Foreign Investment Promotion Act and the Domestic Investment Promotion Act to incorporate the principles of the "Law on Investment Promotion" were enacted. In Laos, the country's land is owned by the nation's community and maintained by the government. Therefore, through the procedures for registration of land, land can be conceded or leased. The ways to invest are joint ventures (where at least 10% of the total capital investment has to be made), foreign sole investment (where the investor must have a minimum capital of $100,000 or more), joint venture agreement and etc. Lastly, the forestation licensing procedures in Laos are carried out in the following order: site selection, business investments feasibility studies, environmental and social impact assessment, forestry permit application.

The purpose of this paper is to introduce the arbitral proceeding system in Indonesia. Arbitration in Indonesia is governed by Law No. 30 of 1999 on Arbitration and Alternative Dispute Resolution (Arbitration Law). Also, the Indonesian National Board of Arbitration (BANI) is the main arbitration body in Indonesia. BANI handles both domestic and international disputes. BANI has published its Rules of Arbitral Procedure (the BANI Rules). Within a period of not longer than 30 days after receiving the petition for arbitration, the respondent must submit its reply. Also, if the respondent wishes to assert against the claimant a counter-claim in connection with the dispute, the respondent may submit such counter-claim together with its statement of defense no later than the first hearing. This paper suggests that the following may be some of the disadvantages to using arbitration under the BANI Rules. The first is that final decision or approval regarding the designation of all arbitrators shall be in the hands of the Chairman of BANI. It is the chief problem facing the international stream of arbitration systems. The second is that arbitrators must have certain minimum qualifications. BANI Rules provide the same requirements for the qualifications of the arbitrators as the Arbitration Law. The third is that the BANI Rules require arbitrators in BANI-administered references to be chosen from BANI's list of arbitrators. BANI can also consider a recognized foreign arbitrator if the foreign arbitrator meets the qualification requirements and is prepared to comply with the BANI Rules. This includes the requirement that the appointing party must bear the travel, accommodation, and other special expenses related to the appointment of the foreign arbitrator.

위험방지를 위한 경찰권 행사는 손해발생의 방지를 최우선 목적으로 한다. 그러나 어디까지를 경찰법상 위험방지영역상의 예방의 대상으로 할 것인가 즉, 그 경계설정의 논의가 최근까지 경찰법상 위험방지영역상의 위험개념을 둘러싼 학설상의 주된 다툼이 되고 있다. 이는 경찰에 의한 공공의 안녕과 질서유지 임무수행은 주로 개개의 위험방지조치를 통하여 이루어 질 수밖에 없으며 예방적 경찰작용은 경찰상의 보호이익에 대한 위험의 방지를 그 내용으로 하는 것으로서 적법한 예방적 경찰작용의 수행을 위해서는 위험에 대한 정확한 이해가 전제되어야 하기 때문이다. 따라서 본 논문에서는 경찰법상 위험에 포섭되기 위하여 최소한도의 위험의 공통된 구성요소를 손해, 충분한 개연성, 시간적 접근성으로 구분하여 각각의 구성요소에서 말하고 있는 법적 의미에 대하여 살펴보고 불확정개념으로서 위험의 해석에 관한 문제를 검토하였다.

An energy-based fatigue life prediction framework was previously developed by the authors for prediction of axial, bending and shear fatigue life at various stress ratios. The framework for the prediction of fatigue life via energy analysis was based on a new constitutive law, which states the following: the amount of energy required to fracture a material is constant. In the first part of this study, energy expressions that construct the constitutive law are equated in the form of total strain energy and the distortion energy dissipated in a fatigue cycle. The resulting equation is further evaluated to acquire the equivalent stress per cycle using energy based methodologies. The equivalent stress expressions are developed both for biaxial and multiaxial fatigue loads and are used to predict the number of cycles to failure based on previously developed prediction criterion. The equivalent stress expressions developed in this study are further used in a new finite element procedure to predict the fatigue life for two and three dimensional structures. In the second part of this study, a new Quadrilateral fatigue finite element is developed through integration of constitutive law into minimum potential energy formulation. This new QUAD-4 element is capable of simulating biaxial fatigue problems. The final output of this finite element analysis both using equivalent stress approach and using the new QUAD-4 fatigue element, is in the form of number of cycles to failure for each element on a scale in ascending or descending order. Therefore, the new finite element framework can provide the number of cycles to failure at each location in gas turbine engine structural components. In order to obtain experimental data for comparison, an Al6061-T6 plate is tested using a previously developed vibration based testing framework. The finite element analysis is performed for Al6061-T6 aluminum and the results are compared with experimental results.

National Health Insurance Act has been enforced all over the People as part of the effort to assure the minimum constitutional human worth and dignity in the aspect of the right to pursue health for preventing misfortune that comes to death without even a chance to be received treatment for illness or injury. Meanwhile auto insurance is compulsory in certain parts in order to promote benefits of everyday life and the rapid recovery of the damage caused by traffic accident when one have negligently driven a car which has become the necessities in daily life. Any injured driver in a traffic accident can be treated by National Health Insurance without getting an auto insurance in various circumstances, but Article 3 paragraph 2 of Traffic Accident Act don't allow exception of criminal punishment when he has driven a car without license, drunken, or tresspassing the centerline, etc. When the injury occured by his own certain negligence is judged to 'when he has intentionally or through gross negligence caused a criminal conduct or intentionally contributed to the occurrence of an accident' of National Health Insurance Act, insurance benefits can be restricted. Such a restriction could harm the right to pursue happiness and health of People by depriving the poor, who cannot afford to pay, of chances to get treatment. Here we will see benefit restriction by 'gross negligence' of National Health Insurance Act Article 48 paragraph 1, which has largest portion of such restriction. It is desirable to delete 'gross negligence' clause from above paragraph and to interpret 'when' clause restrictively for diminishing confusion of interpreting and guaranteeing the right of health.

Crop yields depend on the limiting factor of crop growth; Liebig law of minimum. Identifying the kind and the necessary amount of the limiting factor is essential to increase crop yield. Although nitrogen is the most essential nutrient, N application does not always bring about yield increases when other elements are limiting in rice cultivation. Two experiments were compared to elucidate the effect of soil testing on rice yield response to N level. The one was an experiment about yield response of 3 rice cultivars to 7 levels of N application, which was conducted from 2003 to 2004 in 25 farmer's fields without ameliorating soil conditions by soil testing and the other was a demonstration experiment on N fertilizer recommendation equation by 0, 0.5, 1.0, and 1.5 times of N recommended level in 5 soil types from 30 fields after ameliorating soil conditions by soil testing. The N response patterns of the experiments conducted without soil testing showed a Mitscherlich pattern in some cultivars and soil types, but did not in the others. The N response patterns of the demonstration experiment showed a Mitscherlich pattern in all soil types. Because these results indicated that N was the minimum nutrient in the demonstration experiment by ameliorating soil conditions with soil testing, but not in the other experiment without soil testing, the supply of minimum nutrients by soil testing could increase the efficiency of N-fertilization.

항공운송산업의 선진극인 독일에서는 1994년 새로 제정된 근로시간법(Arbeitszeitgesetz)에서 통상 8시간을 1일 최대근로시간으로 규정하여 1주일간 근로시간을 48시간으로 규정하는 한편, 6개월 또는 24주 이내의 기간을 기준으로 1일 평균 8시간을 넘지 않는 범위 내에서 1일 8시간을 초과하여 10시간까지 근로시키는 것을 가능하게 함으로써 변형근로시간제를 채택할 경우 특정 주의 근로시간을 최대 60시간까지 가능하게 하고 있다. 그리고, 근로시간법에서는 1일 근로의 종료에서 다음 근로의 개시까지는 최소 11시간의 휴식시간을 부여하도록 함으로써 근로자가 1일 동안 사용자의 지휘하에 놓이는 시간의 상한을 13시간으로 제한하는 독특한 입법형식을 취하고 있다. 한편, 근로시간법 제5조, 제7조, 제14조, 그리고 제15조에서는 항공기승무원등과 같이 특수한 형태의 근로를 하는 직종에 대해서는 일반원칙의 적용을 배제하는 예외조항을 두고 있으며, 점포영업시간법에서도 특정한 경우에 대해서는 동법의 적용을 배제하는 예외조항을 두고 있다. 이라한 예외규정에 따라 제정된 행정명령인 항공운송사업자에 관한 2차 볍규명령(2.DV LuftBO)에서는 개별 항공기승무원의 블록시간, 비행근무시간, 휴식시간 등에 대해 자세한 제한규정을 설정하고 있다. 특히, 다른 나라에서는 찾아보기 어려운 시차를 고려한 휴식시간 부여기준 연장이라든가 최대비행근로시간을 1일 20시간까지 가능하도록 직접 규정하고 있는 것은 항공기승무원의 건강을 유지할 수 있도록 함으로써 항공안전을 확보하는 한편, 항공운송산업의 현실을 정확히 반영하고 있다. 독일의 이러한 입법방식은 항공기승무원들의 근로시간 및 휴식시간에 대해 근로기준법과 항공법에서 각각 규정함으로써, 일반 업종 근로자들에게 적용되는 근로기준법의 규정과 항공기승무원들의 근로특정을 고려한 항공법의 규정을 중첩적으로 준수하여야 함으로 인해 각종 문제점을 노정하고 있는 우리나라도 참고하고 도입할만한 우수한 입법으로 판단된다. 아울러 향후 제정될 JAR 부속서 Q에도 반영되어 유럽국가 모두에 적용되어야 할 우수한 제도이다.

In a seminal judgment of November 2002 (Case C-476/98) relating to the compatibility with Community laws of the 'nationality clause' in the 1996 amending protocol to the 1955 U.S.-German Air Services Agreement, the European Court of Justice(ECJ) decided that the provision constituted a measure of an intrinsically discriminatory nature and was thus contrary to the principle of national treatment established under Art. 52 of the EC Treaty. The Court, rejecting bluntly the German government' submissions relying on public policy grounds(Art. 56, EC Treaty), seemed content to declare and rule that the protocol provision requiring a contracting state party to ensure substantial ownership and effective control by its nationals of its designated airlines had violated the requirement of national treatment reserved for other Community Members under the salient Treaty provision. The German counterclaims against the Commission, although tantalizing not only from the perusal of the judgment but from the perspective of international air law, were nonetheless invariably correct and to the point. For such a clause has been justified to defend the 'fundamental interests of society from a serious threat' that may result from granting operating licenses or necessary technical authorizations to an airline company of a third country. Indeed, the nationality clause has been inserted in most of the liberal bilaterals to allow the parties to enforce their own national laws and regulations governing aviation safety and security. Such a clause is not targeted as a device for discriminating against the nationals of any third State. It simply acts as the minimum legal safeguards against aviation risk empowering a party to take legal control of the designated airlines. Unfortunately, the German call for the review of such a foremost objective and rationale underlying the nationality clause landed on the deaf ears of the Court which appeared quite happy not to take stock of the potential implications and consequences in its absence and of the legality under international law of the 'national treatment' requirement of Community laws. Again, while US law limits foreign shareholders to 24.9% of its airlines, the European Community limits non-EC ownership to 49%, precluding any ownership and effective control by foreign nationals of EC airlines, let alone any foreign takeover and merger. Given this, it appears inconsistent and unreasonable for the EC to demand, $vis-{\grave{a}}-vis$ a non-EC third State, national treatment for all of its Member States. The ECJ's decision was also wrongly premised on the precedence of Community laws over international law, and in particular, international air law. It simply is another form of asserting and enforcing de facto extraterritorial application of Community laws to a non-EC third country. Again, the ruling runs counter to an established rule of international law that a treaty does not, as a matter of principle, create either obligations or rights for a third State. Aside from the legal problems, the 'national treatment' may not be economically justified either, in light of the free-rider problem and resulting externalities or inefficiency. On the strength of international law and economics, therefore, airlines of Community Members other than the designated German and U.S. air carriers are neither eligible for traffic rights, nor entitled to operate between or 'free-ride' on the U.S. and German points. All in all and in all fairness, the European Court's ruling was nothing short of an outright condemnation of established rules and principles of international law and international air law. Nor is the national treatment requirement justified by the economic logic of deregulation or liberalization of aviation markets. Nor has the requirement much to do with fair competition and increased efficiency.

Synchrotron radiation of relativistic electrons is an important radiation mechanism in many astrophysical sources. In the sources where the synchrotron cooling timescale is shorter than the dynamical timescale, electrons are cooled down below the minimum injection energy. It has been believed that such fast-cooling electrons have a power-law distribution in energy with an index -2, and their synchrotron radiation has a photon spectral index -1.5. On the other hand, in a transient expanding astrophysical source, such as a gamma-ray burst (GRB), the magnetic field strength in the emission region continuously decreases with radius. Here we study such a system, and find that in a certain parameter regime, the fast-cooling electrons can have a harder energy spectrum. We apply this new physical regime to GRBs, and suggest that the GRB prompt emission spectra whose low-energy photon spectral index has a typical value -1 could be due to synchrotron radiation in this moderately fast-cooling regime.
