  • The purpose of the present study is to identify the damage characteristics of concrete structures due to cracking by employing the acoustic emission techniques. A comprehensive experimental study has been done. The cracking damages under tensile and flexural loadings have been identified and the bond damage between steel and concrete have been also characterized. It is seen that the amplitudes and energy level of AE events is found to be smaller for bond cracking damages and larger for tensile cracking damages. The characteristic equations of the AE events for various cracking damages have been proposed based on the present test data. The internal microcracks are progressively developed ahead of a visible actual crack and the present study clearly exhibits thses damage mechanism for various types of cracking in concrete. The present study provides very useful data which can be used to identify the various types of cracking damages in concrete structures. This will allow very efficient maintenance of concrete structures through monitoring of internal cracking based on acoustic emission.

  • The study tries to suggest one kind of method for measuring expost commutative fisheries damages caused by a large scale coastal reclamation. The situation of fisheries damages which the paper is considering is different from those of general cases:the latter is a priori investigation but the former is a posteriori one. Therefore we need a different approach for exact measurement of such kind of fisheries damages. The key contribution of the paper is to try to estimate a decreasing production function using the results of present investigation and several statistical data about our coastal fisheries productivity and environmental deterioration. Using the function, the paper tries to derive the expected catch amount and damage amount.

  • With the rapid development of oil and chemical industry in the late 20C, massive transportation of oil by oil tanker vessel has grown and it caused the big oil pollution accidents. When oil spill from the oil tanker, damages reach into the astronomical figures in economically and damages affect wide area and many people with break the balance of ecosystem. Recently in Korea, the oil pollution accidents has occurred frequently as growing of oil consumption and it caused large-scale damages to the victim. Oil pollution in Korea offshore takes not only Korean fisherman from their life ground and break the ecosystem but it takes too much time and money to recover. To minimize oil pollution damages, it is necessary to make pre-caution effort as a ship owner and relevant government bodies should endeavor to prevent from more damages. But once oil pollution accidents occurs in territorial sea, compensation for victim is very important. But it is true that compensation is not paid to victim smoothly. So this study aims at the problems of oil pollution compensation to the Korean victim and find the best way to get reasonable compensation.

  • Recently people have come to demand more pleasant environments as the quality and right of life have been improved. Along with industrial development, the tendency is causing a growing number of disputes concerning environmental damages. Of many kinds of environmental damages, noise and vibration pollution rising at construction fields are particularly the most common subjects of public grievance. Thus the government launched the Environmental Dispute Mediation Committee in 1991, purposing to utilize fully the promptness and expertise of administrative institutes and to resolve environmental damage disputes promptly and fairly by interfering in them actively. With the prompt and fair dispute mediations of the committee, people came to be able to get fair and prompt remedies for damages in their health and fortune by environmental pollution. Therefore, by analyzing dispute mediation cases on construction noise and vibration damages, we will suggest basic material on which efficient actions can be taken for public grievances happening in the future.

  • The snow brings affluence if it is dealt with appropriately. but causes huge damages if it is dealt with improperly when it snows heavily. Following with the development of road transportation, tile snow causes damages by becoming a serious obstacle for traffic, increasing traffic accidents, causing damages to the road, and requiring a lot of snow removal expense. As farming in the winter becomes flourishing, damages to agricultural facilities and farm produces caused by the snow become bigger and bigger. Now in our country, heavy snow or heavy rain is likely to fall at anywhere and at any time without restricted to a particular area. Safety first is one way of practicing human respect. Disasters will disappear from our neighborhood if we adopt prevention measures and follow them thoroughly. And also this is the shortcut to achieve a welfare society.

  • In this paper, blast-induced vibration effects on buildings located in rural areas were investigated. Damages to reinforced concrete, adobe and masonry buildings were evaluated in Çatakk$\ddot{o}pr\ddot{u}$ and Susuz villages in Silvan district of Diyarbakir, Turkey. Blasting of stiff rocks to construct highway at vicinity of the villages damaged the buildings seriously. The most important reason of the damages is lack of engineering services and improper constructed buildings according to the current building design codes. Also, it is determined that, inappropriate blast method and soft soil class increased the damages to the buildings. The study focuses on four points: Blast effect on buildings, soil conditions in villages, building damages and evaluation of damage reasons according to the current Turkish Earthquake Code (TEC).

  • In these days, arbitration helps alleviate some of the burden of a heavy caseload from the judiciary and is a viable method to resolve disputes in a relatively quick and efficient manner. An award of punitive damages is often the most significant and detrimental part of an award arising from a judicial or arbitral proceeding. In 1995, the United States Supreme Court resolved a circuit split. upholding an arbitral panel's authority to award punitive damages under a securities arbitration agreement. This decision was monumental in establishing arbitral power. However, it left several questions unanswered. For example, which, if any, standards should be applied to such awards? The decision in Sawtelle, adopting a separate ground for review of punitive damages awards, is one that signals a significant change in the field of arbitration. This article addresses the reviewability of punitive damages awards arising out of a securities arbitration hearing. It would be necessary to introduce securities arbitration system to our disputes resolution system. Compared to American practices, there could be many differences in recognition on arbitration and legal structure in our country. Thus it will be a future assignment to consider seriously and carefully what kind of securities arbitration system will be proper for us. This article analyzed predispute arbitration agreements and agreements to arbitrate after a dispute has already arisen.

  • Article 77 of CISG requires an aggrieved party, the promisee, claiming damages to take reasonable measures to mitigate losses. The reasonable measures required hereunder are limited to those that can be expected under the circumstances having regard to the principle of good faith. When taking such measures, the aggrieved party must do so within a reasonable time under the circumstances. The expenses incurred in taking such measures are recoverable from the promisor. If the aggrieved party fails to do so, the damages recoverable from the promisor are reduced in the amount the loss that should have been mitigated. The aggrieved party's duty to mitigate damages applies to claim for damages only. That is, the violation of this duty should not be invoked against other remedies available under CISG, such as the right to claim specific performance, the right to claim for the price or the right of reduction of price. In practice, under the provision of article 77, the aggrieved party, the seller or the buyer, is often required to enter into a substitute transaction as a measure to mitigate losses and many cases involving a substitute transaction are internationally reported. Therefore this paper intends to provide a certain understanding of the aggrieved party's duty to take measures to mitigate losses based on such cases reported.
