Illegal fishing is often cited as a principal cause of the failure of fisheries management, expecially fishing efforts regulations in traditional fisheries management. Usually, illegal fishing problems are perceived to be equivalent to inadequate enforcement, and policy prescription then follow to strengthen enforcement programs. The purpose of this paper is to analyze the illegal fishing behavior relatively recent emphasis on fishing efforts regulations in traditional fisheries management. The analysis focuses on measuring, explaining and developing the effectiveness way of enforcement strategies responding to imperfectly managed fishing efforts regulations through illegal fishing behavior and avoid enforcement fishing efforts measures. A model of fishermen fishing behavior and profit-maximizing decision making is analyzed to determine optimal fishing at individual fisherman level in response to fishing efforts regulation. The results of economic analysis of the enforcement of illegal fishing in traditional fisheries management results are as follows: First, illegal fishing will occur only if enforcement effort is not so high as to remove the incentive to do so, and if the effectiveness of avoidance is not too great, nor its cost too low. Second, avoidance effort will occur at a level jointly proportional to the extent of illegal activity and of enforcement; for given levels of the latter, the desired avoidance effort increase with its effectiveness and decrease with its cost Third, to improve the effectiveness of enforcement, understanding avoidance behavior appears to be crucial to any efforts. Forth, enforcement and fishermen behavior interact depends strongly on characteristics of avoidance, specifically its cost and effectiveness. When avoidance is neither too cheap nor too effective, the interaction is regular. Fifth, in this case, at low levels of enforcement, fishers respond to increases in enforcement by increasing avoidance, but at higher enforcement levels, it becomes uneconomical to continue to do so, and avoidance decreases with enforcement. Sixth, illegal fishing activity decreases steadily with enforcement, so the fishery manager is able, in theory, to reduce illegal fishing toward zero by increasing enforcement. If, however, avoidance is very inexpensive and/or very efficient/ then the optimal level of avoidance will increase indefinitely with increasing enforcement. Finally, less fishery enforcement is required if fishermen have less incentive to overfish, and fishermen have less incentive to avoid fishery enforcement measures.

교통사고로 인한 여러 가지 사회적 문제들로 인해 정부에서는 강력하게 교통사고를 줄이기 위한 여러 가지 정책들을 시행하여 왔다. 이러한 결과들로 인해 최근 들어 교통사고 발생건수 및 사망자 수가 감소추세에 있다. 그러나 이러한 교통사고 감소를 위한 여러 가지 정책들을 시행하기 위해서는 비용이 수반되게 마련이며, 이에 대한 비용 대비 효과 평가도 이루어질 필요가 있다. 본 연구에서는 최근 교통단속에 투자되는 비용 가운데 단속효과가 입증된 무인과속단속시스템에 의한 단속과 교통경찰에 의한 인력단속의 경우를 단속이 없는 경우와 비교하였다. 그 결과 평균속도에서 설치전 조건이 평균속도 82.66km/h, 인력단속 조건이 70.57km/h, 기계적 단속조건이 67.85km/h순으로 높게 나타났고 통계적으로도 유의한 차이가 있었다. 또한 제한속도 위반율에서도 설치전 조건이 65%, 인력단속조건이 32%, 기계적 단속조건이 19%의 순으로 나타났다. 차종별로는 승용차, 승합차, 화물차의 순으로 평균속도 및 위반율이 높았으며, 차로별로는 1차로가 2차로에 비해 높게 나타났다. 이와 같은 결과를 토대로 사고율을 추정하여 투입비용 대비 편익을 측정하였는데 무인과속단속시스템 설치전 조건의 경우와 비교하여 연간비용대비편익을 추정하였다. 그 결과 교통경찰에 의한 인력단속조건의 경우 76,130,590원의 마이너스편익이 발생하였고, 무인과속단속시스템에 의한 기계적 단속의 경우 38,577,670원의 편익이 발생하는 것으로 추정되었다

This study was conducted to analyze the cost effectiveness in line with total phosphorus standard enforcement of public sewage treatment facilities. The additional cost for the total phosphorus removal process was calculated to analyze the cost effectiveness of the advanced water purification process. The analysis results showed that the T-P removal by coagulation sedimentation was more efficient than the advanced water purification facilities in terms of facilities investment cost, and if the coagulation filteration was used for T-P removal, the activated carbon process among the advanced water purification techniques was more efficient in terms of facilities investment cost. In this study, the effects of the T-P removal process that will be additionally introduced according to the tightening of the effluent T-P standard were analyzed within a limit. The actual benefits of improved T-P concentration in the water source will provide diverse values, including the leisure water, environment improvement water, eco-system in the water source and industrial water, in addition to the advanced water purification.

Apartment housing in the Korean domestic construction industry has had various and high-quality finishing work since the enforcement of price deregulation in 1998. Before the enforcement of price deregulation, feasibility studies of housing projects have not had particular difficulties as uniform description of finishing work items were reflected and finishing work cost also was equalized. However, the recent distinction of finishing work based on the same floor plan brings about project cost variation, along with many effects on construction management due to project cost increment. Accordingly, this paper suggests the improved plan of cost management to control the feasibility study result consistently during the life cycle of a project through an analysis based on cost management phase due to cost blackout, appearing at the commencement of a project, cost gradation caused by high-quality finishing work item, and cost reduction due to the degradation of finishing work after analysis of current apartment construction process focused on finishing work using the IDEF process analysis technique.

Korean businesses, and their legal representatives, have observed the improvements of enforcement of commercial judgments through arbitration over traditional collections litigation in U.S. Courts-due to quicker proceedings, exceptional cost savings and more predictable outcomes-in attaching assets within U.S. jurisdictions. But how are the 2016 interim measures implemented by the Arbitration Act of Korea utilized to avoid jurisdictional and procedure pitfalls of enforcement proceedings in the Federal Courts of the United States? Authors examine the necessary prerequisites of the U.S. Federal Arbitration Act as adopted through the New York Convention, to which Korea and the U.S. are signatories, as distinguished from the Panama Convention. Five common U.S. arbitration institutions address U.S. "domestic" disputes, preempting U.S. state law arbitrations, while this article focuses on U.S. enforcement of "international" arbitration awards. Seeking U.S. recognition and enforcement of Korean arbitral awards necessitates avoiding common defenses involving due process, public policy or documentary formality challenges. Provisional and conservatory injunctive relief measures are explored. A variety of U.S. cases involving Korean litigants are examined to illustrate the legal challenges involving non?domestic arbitral awards, foreign arbitral awards and injunctive relief. Suggestions aimed toward further research are focused on typical Korean business needs such as motions to confirm foreign arbitration awards, enforce such awards or motions to compel arbitration.

This paper reviews the problems on the arbitral awards enforcement in the 2016 Korean Arbitration Act. In order to get easy and rapid enforcement of the arbitral awards, the new arbitration act changed the enforcement procedure from an enforcement judgement procedure to an enforcement decision procedure. However, like the old arbitration act, the new act is still not arbitration friendly. First of all, there are various problems in the new act because it does not approve that an arbitral award can be a schuldtitel (title of enforcement) of which the arbitral award can be enforced. In this paper, several problems of the new act are discussed: effect of arbitral award, approval to res judicata of enforcement decision, different trial process and result for same ground, possibility of abuse of litigation for setting aside arbitral awards and delay of enforcement caused by setting aside, infringement of arbitration customer's right to be informed, and non-internationality of enforcement of interim measures of protection, inter alia. The new arbitration act added a proviso on article 35 (Effect of Arbitral Awards). According to article 35 of the old arbitration act, arbitral awards shall have the same effect on the parties as the final and conclusive judgement of the court. The proviso of article 35 in the new act can be interpret two ways: if arbitral awards have any ground of refusal of recognition or enforcement according to article 38, the arbitral awards do not have the same effect on the parties as the final and conclusive judgement of the court; if arbitral awards have not recognised or been enforced according to article 38, the arbitral awards do not have the same effect on the parties as the final and conclusive judgement of the court. In the case of the former, the parties cannot file action for setting aside arbitral awards in article 36 to the court, and this is one of the important problems of the new act. In the new act, same ground of setting aside arbitral awards can be tried in different trial process with or without plead according to article 35 and 37. Therefore, progress of enforcement decision of arbitral awards can be blocked by the action of setting aside arbitral awards. If so, parties have to spend their time and money to go on unexpected litigation. In order to simplify enforcement procedure of arbitral awards, the new act changed enforcement judgement procedure to enforcement decision procedure. However, there is still room for the court to hear a case in the same way of enforcement judgement procedure. Although the new act simplifies enforcement procedure by changing enforcement judgement procedure to enforcement decision procedure, there still remains action of setting aside arbitral awards, so that enforcement of arbitral awards still can be delayed by it. Moreover, another problem exists in that the parties could have to wait until a seventh trial (maximum) for a final decision. This result in not good for the arbitration system itself in the respect of confidence as well as cost. If the arbitration institution promotes to use arbitration by emphasizing single-trial system of arbitration without enough improvement of enforcement procedure in the arbitration system, it would infringe the arbitration customer's right to be informed, and further raise a problem of legal responsibility of arbitration institution. With reference to enforcement procedure of interim measures of protection, the new act did not provide preliminary orders, and moreover limit the court not to recognize interim measures of protection done in a foreign country. These have a bad effect on the internationalization of the Korean arbitration system.

This paper is aimed to analyze how to evaluate the choice of optimal management measures and level of control in fisheries management under the costly and imperfect management system by comparing with costless and perfect management system that is commonly assumed in the analysis of fisheries regulations. Fishermen would set the level of fishing efforts at the point where the marginal fishing profit for fishing effort is equal to the marginal level of fine under costly and imperfect management system. Therefore, under the case where the marginal fishing profit is higher than the marginal level of fine, the level of fishing efforts would be made at the point which is higher than the level of fishing efforts made under costless and perfect management system and is not a point where the economic profit is maximized in regulated fisheries. From this conclusion, the fishermens avoidance activities against regulations as well as the level of control in fisheries management substantially have an influence on the choice of fisheries management instruments. According to the analysis of optimal fisheries management policy, the economic profits in regulated fisheries are determined by the level of fisheries enforcement costs and total fishing profits, in which as enforcement costs increase the economic profits decrease. In addition, the economic profits vary in response to the level of control in avoidance activities. That is, as avoidance costs decrease, the economic profits increase. The determination of optimal level of control in fisheries management should be made at the point where the marginal regulation costs are equal to the marginal profits from regulated fisheries, in which marginal regulation costs are different according to the type of management measures. And the level of profits changes in response to different levels of avoidance activities. The management measure that can maximize the difference between the marginal regulation costs and marginal profits from regulated fisheries should be chosen as an optimal fisheries management instrument.

In order to overcome the limitations of the mobile speed system for 1 lane, this study is used a multi-laser beam to develop a mobile speed measuring system, using a multi-phase beam. By using multi-laser beam, least squares algorithms and speed error processing algorithms were developed to improve speed accordancy and speed error rates compared to conventional mobile speed meters using a single laser beam. A field test showed that 80.0 percent of 3 lane and 87.0 percent of 4 lane were appropriate for the mobile speed system. With the development of the mobile speed measuring system, it is expected to dramatically reduce the accidents caused by the speed of traffic. It is also expected to effectively operate equipment and manage the cost by improving manpower and providing improved enforcement accuracy, by contributing positively to public institution and public affairs.
