  • This paper presents a novel control methodology for communication network based nonlinear systems with time delay nature. We construct a nominal nonlinear control law for representing a linear model and a reset control system which is aimed for corrective control strategy to compensate system error due to uncertain time delay through wireless communication network. Next, online neural control approach is proposed for overcoming nonstationary statistical nature in the network topology. Additionally, DBN (Dynamic Bayesian Network) technique is accomplished for modeling of its dynamics in terms of casuality, which is then utilized for estimating prediction of system output. We evaluate superiority and reliability of the proposed control approach through numerical simulation example in which a nonlinear inverted pendulum model is employed as a networked control system.

  • Shipping protectionist measures are imposed to help the national fleet based on the protection that shares are low and that there are economic benefits from increasing them. Relative to the complexity of those objectives, protection is fairly simple and blunt instrument of policy. Shipping protectionist measures are classified into two groups on the basis of the nature of protectionist tools; finance-oriented and non-finance oriented instruments. The thesis aims to show non-finance oriented shipping instruments in the pre-WTO Period. Chapter 2 deals with the development of protectionism in shipping. Chapter 3 Classified non-finance oriented protection such as Cargo Reservation, Cargo Sharing and Cargo Control. Chapter 4 outlined and examined the effect of Non-Finance Oriented Shipping Instruments which was the most important in developing countries.

  • A time-optimal control law for quick, strongly nonlinear systems has been developed and demonstrated. This procedure involves the utilzation of neural networks as state feedback controllers that learn the time-optimal control actions by means of an iterative minimization of both the final time and the final state error for the systems with constrained inputs and/or states. A neural identifier or a genetic algorithm identifier could be utilized for modeling the partially known systems and the unknown systems. The nature of neural networks as a parallel processor would circumvent the problem of "curwe of dimensionality". The control law has been demonstrated for both a torque input motor and a velocity input motor identified by a genetic algorithm called GENOCOPed GENOCOP.

  • Many modern guided weapon systems employ sophisticated target sensors as well as powerful computing systems. Due to such advanced features, they are required to achieve better guidance accuracy, and at the same time other guidance objectives for better weapon effectiveness and survivability. In this paper, we overview some of the technical considerations in such advanced guidance algorithm development, and briefly look at some related research works. More specifically, we discuss impact angle control, time-varying nature of the guidance system, time-to-go estimation, guidance loop stability, effect of autopilot lag and physical limitations in control variables, parasitic paths in guidance loops, etc. We also briefly look at some advanced concepts such as integrated guidance and control loop design, target adaptive guidance, guidance law development based on dual control concept, and terminal evasive maneuver.

  • The study covers three components of the facility for protecting public utilities market participants in the public utilities market: prevention of potential poverty, reduction of existing poverty and compensation to the injured party in a case of tort that exacerbates or threatens to exacerbate its poverty. The analysis is based on official statistical information on the activities of the public utilities sector. Operational information of public utility service providers regarding certain indicators of their activity in the work was not studied. This approach narrows the empirical basis of the study, but at the present stage in the context of different rates of implementation of changes in regions, sectors and at the level of individual entities, as well as lack of uniformity in the structure of indicators published by service providers, analysis allows to identify «bottlenecks» of legal regulation, which are systemic in nature and largely independent of the subjective factor.

  • To succeed the claim of medical malpractice litigation, the patient as a plaintiff should establish the medical fault of a physician as a defendant, and the causation between the fault and damages. Because of the extraordinary nature of medical province, however, this application of a legal principles is rigorous with the patient. In addition, given the causation between the validation of physician's fault and damage is not attested, patient is not awarded anything. In order to overcome a difficulty of patient's verification and ensure the right to fair process, it was demonstrated the lightening of burden of proof in medical malpractice litigation and the acceptance of the responsibility for an illegal act in a prescribed range in the absence of the causation between the physician's fault and damage. This paper deals with the judgement of causation and burden of proof in medical malpractice litigation, and the acceptance of responsibility in the absence of the causation between the physician's fault and damage. Also, this study recommends a tendency of our precedent through the comparative case method of ours and Japan.

  • Documentary credit transactions are judged by the principle of strict compliance. The compliance of the tendered documents with the credit's teams ensures the proper completion of the underlying transaction. But if the documents tendered by beneficiary differ, a discrepancy of documents occurs. Such a discrepancy raises difficult problems for the bank to which the documents are tendered. It has to decide whether to reject or accept them or to accept them under a protective mechanism. Therefore, this study is to examine the case study of complying presentation of the description of the goods in documentary credit through the Korean Supreme Court Cases. The objectives of this paper are as follow : 1. To examine two point of views on document compliance such as strict compliance and substantial compliance. 2. To analyze Korean Case Law which challenges the legal conclusions, standard for examination of documents and New ISBP. 3. To draw out the criterion for conformity and discrepancy of description in invoices and WC and to provide the guidelines for determining the nature and extent of an issuing bank's duty of documentary compliance. 4. Finally to suggest some implications through the Korean case law. By using the examination standards for description of goods suggested in Korean Case Law and New ISBP, the traders will be able to prepare documentation more perfectly and document checkers will be able to examine the negotiation documents more easily.

  • Retentions are generally considered to be intended to act as a powerful tool to incentivize contractors/subcontractors to remedy defective work in cases of non-performance. This study attempts to establish the extent to which retentions can be used for this purpose by investigating case law connected with insurance and defective work. One of the significant questions is whether retentions are sufficient to deal with construction defects or value of retentions in the rectification of defects is illusory. The cost to repair a defect may vary depending on a number of components including type, cause, magnitude and the construction stage at which the defect occurs. It is expected that a review of existing cases on defective workmanship will provide an insight on the issues and whether retentions are effective in their intended function. In order to establish their functionality, the study described in this paper investigated 6 construction insurance cases to identify the critical issues and the causes of dispute. It was found that the nature and the cause of defects were different in each case. It was also established that certain defect types not covered by insurance may be covered by retentions - potentially one of the key uses of a retention strategy. It is expected that the findings will assist in forming a view on the quantum of money that may be required paving the way for a first time understanding on a rational basis for setting up retention regime.

  • A criminal liability of the divisional medical-institution is faced a new aspect in the connection with development of the medical techonology. Especially, a division of labor in the medical-institution in Korea will be greatly increased in the foreseeable future. A general hospital will be frequently confronted with sofisticated techniques such as MRI, CT-screen. Accordings to the nature of its functions, a general hospital may make accommodation or services or both available for patients who give undertakings (or for whom undertakings are given) to pay, in respect of the accommodation or services (or both) such charges as the government may determine. It shall be the duty of the government to develop, promote and regulate a criminal liability of the divisional medical-institution. Above all, the government shall have to determine the standard of a criminal liability of the medical-institution in the horizontal specialization and the vertical specialization. But, the court may give finally by directions the standard of the criminal liability of the divisional medical-institution.

  • Ethics suggest that all persons are by nature moral, as it would not be possible for humans to exist collectively or even individually without an innate ethical sense. In order for the public sector to thrive in business, the board of directors needs to be guided by ethics and take into account the abiding interests of humanity and public good. It is argued in this paper that the abuse of power in the public sector has often been associated with unethical leadership and conducts which undermines the ubuntu notion. The irregularities which often arise in the awarding of tenders in the state-owned companies are some of the challenges that are prone to the public sector. In order to address these challenges and promote a flourishing democracy it is argued that ethical leadership as envisaged in the King III Report needs to be adhered to by the boards of directors. This paper concludes that the direction and control of ethics in any organisation is vital especially where the line between corporate governance and ethical leadership has become blurred.
