Despite of the long history of comic industry in Korea, self-motivated sound ecosystem is not determinded due to the pirated contents. The file-sharing literature has focused mainly on how pirated contents could be eradicated, with less attention to the effective strategy. This research is focusing more on pirate comic market within the framework of users. The target user is people who pay for using file sharing site. The research methods are a online survey and a written interview. The goal of this research is to analyze the correlation between morality and websites uses, the user convenience of file-sharing site and the main factors for attracting user to legal portal site. According to our results, legal portal sites needs to improve purchasing factors such as diversity of contents, improvement of payment system and offer of a detailed information.

As the existing metropolitan area metropolitan railway operates on a one-to-one basis, which leads to long travel times, its competitiveness with other means of transportation is deteriorating. Since there is a limit to attracting road traffic by rail, there is a continuing societal demand to expand express train service. Especially in the northern and the southwestern parts of the metropolitan area, a public transportation network system with express function, connecting to the city center of Seoul, is needed because of the social cost of the increase of traffic congestion and the increase of the travel time. The most efficient express service in Korea is Seoul Subway Line 9, which runs in 27 minutes from Gimpo Airport to the high speed terminal; this is a 40% shorter time compared to 44 minutes by car; the congestion in this area is up to 240%, so the preference for this train is quite high. The technical results of this study are expected to contribute to the implementation of an express service metropolitan railway.

Traditionally, tariffs have been used to protect domestic industries. In particular, a country with more bargaining power makes a punitive threat to maintain a certain level of market share in the market of other country. In this paper, we study the effect of punitive tariffs on an irrelevant industry. In particular, when a country tries to achieve a market share or quantity target in an industry, we examine the effect of threats to impose tariffs on the major export of another industries which are irrelevant to the targeted industry. Using a simple duopoly model, we show that there is a Cournot-Nash equilibrium which supports that a country has an incentive to resolve a trade dispute voluntarily to protect its major export industry under the credible treat of punitive tariffs. This result is mainly due to the fact that the trade policy of a country concerns the aggregate benefits from trade over all its export industries. To obtain this result, this paper employs the linkage between the targeted and irrelevant industries by using the lobby of the irrelevant industry to curb the targeted industry. A lot of recent bilateral trade agreements can be applied to our results.

MMO RPG Online game as a new means of human computer interaction has been made rapid progress. Even though many kinds of online game have published, few games are being well received by its user. So we have a problem to be solved what is the fundamentals to attract game users. I will apply a game theory of the Roger Caillois who lived as an typical french thinker. Although Roger Caillois had never experienced a computer game since he died at 1978, his game theory was acknowledged that a game can be classified into four sections to grab the human's interest related with culture. Four sections of game were consisted of Ilinx, Mimicry, Alea, and Agon. The competition with people in game is essential to "Agon" that which stands on the basis of a pride when one is definitely superior to the others. In same way, "Alea" is that which stands on the basis of fortune, Mimicry is that which stands on the basis of simulation, Ilinx is that which stands on the basis of dizzy. In conclusion, I will explain that a game theory of the Roger Caillois is useful tool for deveoper to understand game fundamentals.d game fundamentals.

These days, environmental policies have changed from being command and control systems toward economic incentive systems, with various incentives having been established by OECD countries. In Korea, many environmental charges have been established in order to diminish activities which damage natural resources. Among them, the Ecosystem Conservation Cooperation Charge and the Replacement Charge for Forest Resources Creation are considered to be representative environmental charges. These charges, along with a few others, were designed to encourage efforts to protect natural resources. The charges include a number of different features, utilize varying methods, and altered ranges of jurisdiction. However, the charges may pose serious inequity problems in terms of their estimated values and their conditions of reduction and exemption. For instance, although the Ecosystem Conservation Cooperation Charge is a primary charge applied to natural resource damage, the charge does not fully secure its original objectives due to its low levy and limited range of provisions. Moreover, the Replacement Charge for Forest Resources Creation has been criticized because of similar reduction and exemption provisions. Therefore, this study analyzes the inequity problems associated with the charges and proposes solutions. First of all, the Ecosystem Conservation Cooperation Charge should be redesigned in such a way that it reflects the substantial value of natural resource damage through either abrogate or increased maximum limits of the charge. With regard to the Replacement Charge for Forest Resources Creation, the cases and ranges of reduction and exemption provisions should be narrowed. Finally, the charges collected should be expended in conformity with their original objectives, and their expenditure should be restricted to either restoration activities or activities directly related to compensation and mitigation of damaged natural resources.

Serial violent crimes have occurred more frequently. Additional attention is paid to relevant areas in which discussions has also increased. This study analyzed Young-cheol Yoo, serial killer case. Two of Yoo's crimes were studied for modus operandi. The cases selected were the premeditated break-in homicide of upper-class elderly people and the impulsive homicide of the Hwanghak-Dong street vendor. Crime motives, targets, times, places, means and methods were analyzed. Profiling techniques in Young-cheol Yoo cases were evaluated and the problems discovered during investigation were discussed. The followings are the findings of the analysis of the serial killer Yoo cases. Yoo exhibited a hatred toward the rich, the elderly, and women as well as a fear of diseases and death. Yoo's crime targets were the elderly residing in wealthy houses, street vendors and prostitutes. The numbers of victims were: 3 men and 5 women victims in 4 homicide cases involving the elderly residents in wealthy houses; one man in 1 street vendor homicide case 11 women in 11 prostitute homicide cases, so total 20 persons were murdered in 16 cases. The time of the crimes were between 10 am and noon in the homicide cases of the elderly and very late at night or early in the morning in the prostitute homicide cases. Means and methods facilitated include the use of a knife as a threat and a hammer made by Yoo to strike the head and face of victims. In the homicide cases involving the elderly, he attempted to disguise the crime scene as a burglary or committed arson to destroy the evidence; in the prostitute homicide cases, bodies were mutilated and buried in secret. 1) Generally each serial killer case has different characteristics, motives, and purposes; while some serial killer cases involve similar methods, others use different methods. Unlike other crimes, serial killers' characteristics and tastes are very different, so it is difficult to explain serial killings based on a specific model. It is important to accurately capture modus operandi of each serial killing and for detectives to familiarize themselves with them. The process of tracing and use of imagination which follows a serial killer's psychology and thought must be used to find out what kind of thoughts pushed the killer to commit the crime. In order to investigate and research difficult subjects such as serial killing, various methods, skills, and relevant knowledge should be studied, and institutional endeavors should go hand in hand with individual efforts.

Our Constitution obliges the state to protect the health of the people, and the Medical Law, which embodied Constitution, sets out in detail the matters related to open the medical institution, and one of them is to prohibit the operation of multiple medical institutions. By the way, virtually multiple medical institutions could be opened and operated because the Supreme Court had interpreted that several medical institutions could be opened if medical activities were not performed directly at the additional medical institution which was opened under the another doctor's license. However, some health care providers opened the several medical institutions with another doctor's license for the purpose of the maximization of profit, and did illegal medical cares like the unfair luring of patients, over-treatment, and commission treatment. Also, realistic problems such as the infringed health rights have arisen. Accordingly, lawmakers had come to amend the Medical Law to readjust the system of opening for medical institution so that medical personnel could not open or operate more than one medical institution for any reason. For this reason, the Constitutional Court recently declared a constitutional decision through a long period of in-depth deliberation because the constitutional petition and the adjudication on the constitutionality of statutes had been filed on whether Article 33 paragraph 8 of the revised medical law is unconstitutional. The Constitutional Court acknowledged the "justice of purpose" in view of the importance of public medical institutions, of the prevention from seduction of for-profit patients and from over-treatment, and of the fact that health care should not be the object of commercial transactions. Given the risk that medical personnel might be subject to outside capital, the concern that the holder of the medical institution's opening certificate and the actual operator may be separated, the principle that the human body and life should not be just a means, and the current system's inability to identify over-treatment, it also acknowledged the 'minimum infringement'. Furthermore, The Constitutional Court judged it is constitutional in compliance with the principle of restricting fundamental rights, such as 'balance of legal interests'. In this regard, legislative complements are needed in order to effectively prevent the for-profit management and the over-treatment the Constitutional Court is concerned about. In this regard, consumer groups actively support the need for legislation, and health care providers groups also agree on the need for legislation. Therefore, the legislators should respect the recent Constitutional Court's decision and in the near future complete the complementary legislation to reflect the people's interests.

Coastal monitoring using multiple platforms/sensors is a very important tools for accurately understanding the changes in offshore marine environment and disaster with high temporal and spatial resolutions. However, integrated observation studies using multiple platforms and sensors are insufficient, and none of them have been evaluated for efficiency and limitation of convergence. In this study, we aimed to suggest an integrated observation method with multi-remote sensing platform and sensors, and to diagnose the utility and limitation. Integrated in situ surveys were conducted using Rhodamine WT fluorescent dye to simulate various marine disasters. In September 2019, the distribution and movement of RWT dye patches were detected using satellite (Kompsat-2/3/3A, Landsat-8 OLI, Sentinel-3 OLCI and GOCI), unmanned aircraft (Mavic 2 pro and Inspire 2), and manned aircraft platforms after injecting fluorescent dye into the waters of the South Sea-Yeosu Sea. The initial patch size of the RWT dye was 2,600 ㎡ and spread to 62,000 ㎡ about 138 minutes later. The RWT patches gradually moved southwestward from the point where they were first released,similar to the pattern of tidal current flowing southwest as the tides gradually decreased. Unmanned Aerial Vehicles (UAVs) image showed highest resolution in terms of spatial and time resolution, but the coverage area was the narrowest. In the case of satellite images, the coverage area was wide, but there were some limitations compared to other platforms in terms of operability due to the long cycle of revisiting. For Sentinel-3 OLCI and GOCI, the spectral resolution and signal-to-noise ratio (SNR) were the highest, but small fluorescent dye detection was limited in terms of spatial resolution. In the case of hyperspectral sensor mounted on manned aircraft, the spectral resolution was the highest, but this was also somewhat limited in terms of operability. From this simulation approach, multi-platform integrated observation was able to confirm that time,space and spectral resolution could be significantly improved. In the future, if this study results are linked to coastal numerical models, it will be possible to predict the transport and diffusion of contaminants, and it is expected that it can contribute to improving model accuracy by using them as input and verification data of the numerical models.

The Social Economy including social enterprise is solving various social problems of our society by innovative business Nevertheless, social economic companies have limited investment ingrowth due to insufficient capital. There are various attempts to solve the limit of capital investment by social finance. Social iImpact bonds that introduced performance-based compensation into financial system is recognized as a new means of procuring that capital lacks. 89 social impact bonds were issued in 19 countries around the world. )f the 22 social impact bonds reporting performance, 21 bonds report positive performance. The twelve bonds paid incentives to investors. It can be said that the government provides incentives to review the issuance of social impact bonds at the government level, which is difficult to expand the social welfare budget. This study confirmed the performance of the social impact bonds and confirmed the possibility of introducing it in korea. There is a limit to continuously increasing the government's social expenditure to meet demand. Therefore, in order to support the growth of social economy based on private investment, the issuing of social impact bonds should create a virtuous circle of social financial market.

이 논문은 2002년도 부경대학교 수산경영학과 박사학위논문(A Study on Institutional Arrangements for Quota-Based Management : The Case of China's Marine Capture Fisheries)의 일부이다. 이 논문의 기본목적은 취터제에 기초한 중국의 어업관리를 위한 제도적인 틀을 세우고자 하는데 있으며, 이런 목적을 달성하기에 위해 이 논문은 다음과 같이 구성하여 연구를 진행시켰다. 제1장은 연구목적과 문제의 제기에 이어 제2장에서는 중국 해양어업의 개발과 이에 따른 문제점을 분석하였으며, 여기에서 궈터제에 기초한 어업관리정책의 제도적 제안을 함과 동시에, 제3장에서는 중국 해양어업의 현실과 중국 사회의 일반적인 현상을 분석하여 제4장을 통해 쿼터제에 기초한 중국의 어업관리를 위한 제도적 프레임러크를 제안하였다. 마지막으로 본 논문을 요약하고 향후 계속되어야 할 연구과제를 제시하였다. 본 논문의 중요한 연구 결과는 다음과 같다. 현재 중국 수산업의 관리체제는 질적 규제 중심 관리제도, 그리고 정부 주도하의 어업관리 과정으로 특징지을 수 있다. 이러한 명령과 통제 (command-and-control) 방식의 전통적인 중국어업 관리제도로서는 어업인들에게 있어서 자원 보존에 대한 동기와 제도에 대한 수용성을 약화시키며, 정부 규제를 오히려 무시하게 되는 결과를 초래한다. 결과적으로 현형 중국의 어업관리제도는 어업인에게 있어서 자원 보전에 대한 유인을 약화시키고 단기적인 수익을 극대화하도록 유도하는 맹점을 지니므로 인해 더 이상 지속적인 어업성립의 보장을 할 수 없다는 점을 지적할 수 있다. 중국정부는 이러한 어업관리제도의 불완전성을 인식하여 2000년 10월 31일에 1986년 에 제정된 수산업법을 개정하게 되었으며, 새로운 중국의 수산업법은 어업 허가제도와 함께 할당량제에 기초한 어업관리제도를 국가가 운영하는 것으로 특징지을 수 있다. 그러나 아직까지 중국은 할당제에 근거한 어업관리제도를 미실시중에 있으며, 그 내용도 애매모호한 점을 많이 가지고 있다. 또한 중국의 절대적 어획량은 현재 논란의 여지로 남아있고, 거대 어업 인구의 근본적인 요구와 중국 어선의 국제적인 경쟁력, 그리고 유어(遊漁)에 대한 사회적 요구 등도 중국의 수산정책이 채결해야 할 과제이다. 위에서 고찰한 내용을 기초로 하여 우리는 중국의 쿼터제에 기초한 어업관리에 대해 다음과 같은 몇 가지를 제안한다. 중국 연근해어업에 있어서 할당제 모형에 참가하는 어업 참여자들의 유형은 세 가지로 구분할 수 있다. 첫째는 어촌에 거주하면서 생존수단으로 소규모 어업에 종사하는 경우이고, 둘째는 유어어업의 경우이며, 셋째는 상업적 목적으로 어업에 종사하는 집단으로 나눌 수 있다. 이러한 세 집단을 하나의 제도의 틀로 통합하기 위해서는 국가의 총허용어획량(TAC)을 총 어촌 허용어획량(TAIVCs)과 총 허용 유어 어획량(TARCs) 및 총허용 상업적 어획량 (TACCs)의 세부문으로 나눌 것을 제안한다. 그리하여 다시 TAFVCs와 TARCs, 그리고 TACCs는 어촌별 어획량(ITCQs), 개별 유어 회사별 어획량(IRCQs), 그리고 양도 가능한 개별 상업적 어획량(ITCQs)으로 나누어 관리하도록 한다. 이와 같이 중국의 국가 총허용어획량(TAC)을 IFVQs와 IRCQs, 그리고 ITQCQs의 세부문으로 구분하여 할당하고, 여기에 기초하여 어업을 관리하는 것은 중국에 있어서 사회적 형평성과 경제적 효율성과의 상충관계를 고려하여 고안된 것으로, 중국에 있어서 수산업을 통한 경제적 및 사회적 효과를 동시에 기대할 수 있을 것이다.
