「IMF 시대」대미 외교의 방향

김성한 한국전략문제연구소 1998 전략연구 Vol.5 No.3

Ⅰ Korea's economic crisis has begun to force potentially important changes in the peace-building process on the Korean peninsula. The inauguration of President Kim Dae-jung under the financial crisis has led to a more conciliatory South Korean policy toward North Korea, thereby broadening public support in South Korea for the 'engagement' policy to North Korea while dampening desires for near-term Korean reunification. Recent developments on the Korean peninsula will require closer policy coordination between the United States and Korea on a broad range of issues including the KEDO process. Tactical coordination on such issues as food aid. progress in the pace of North-South relations, how to apply or relieve political and economic sanctions on North Korea, and how to respond to sudden economic and political changes in North Korea is exceedingly difficult, but critical. In order to make the Korea-U.S. policy coordination more effective, first of all, the Korean government needs to convince the U.S. government that the U.S. remain South Korea's ally rather than playing the role of a mediator between the two Koreas. The Clinton Administration could attempt to mediate between the two Koreas in the four-party peace process. Thus, Korea needs to. emphasize to the U.S. for instance, that the past data on North Korea's nuclear program be preserved and that the issue of North Korean missiles be dealt with not only in terms of their export problem but also of their development and deployment on the peninsula. Second. Korea and the U.S. should make all efforts to make their alliance enter a consolidation stage in which they frequently consult each other on bilateral as well as regional issues and seek agenda-building on the basis of shared democratic values between the two countries. In order to make it possible. Korea needs to well manage. through the political leadership. its relationship with China and the increasing cynicism of the conservative middle class to the U.S. Finally. on the basis of the mutual security alliance between Korea and the U.S.. a collective security system for the Northeast Asian region needs to be created. While bilateral security arrangements will remain the backbone of Northeast Asian security for a considerable period of time. the emerging new order raises the need for such a multilateral setting as the NEASED that was proposed by the Korean government in 1994. Korea should try to make it feasible and also actively participate in the multilateral activities at the track-II level. Ⅱ One important area where the interests coincide between the U.S. and Korea is one in which Korea. for the purpose of survival. and the U.S.. in order to protect its leadership, need an equilibrium within the region where Korea is located. An hegemonic order in Northeast Asia would threaten the U.S. leadership position as well as the political independence of Korea. However. the convergence of interests does not always guarantee policy coordination, since Korea and the U.S. can have different policy priorities. The resolution for the priority divergence between Korea and the U.S. can be achieved through redefinition of the alliance that is to be focused on regional priorities. In other words, both countries need to put their first priority on the strategic interests in Northeast Asia including the Korean peninsula. This is the way by which the global interest of the U.S. and the peninsular interest of Korea can be converged at the regional level. Thus, both countries should emphasize that the Korea-U.S. alliance. that was created to deter North Korea's military threat, will ultimately contribute to stability in Northeast Asia. and that the alliance will continue even after the threat from North Korea disappears. In addition. Korea and the C.S. should start preparing for crisis management in the case of North Korea's sudden collapse. Ⅲ Korea and the U.S. will have to begin consulting each other concerning the necessary steps to transform the alliance into the regional one. A key issue that is to be put on the table will be the role and force structure of the U.S. forces in unified Korea. Korea and the U.S. will have three options. They have to decide whether they will actually terminate the alliance by completely withdrawing American troops from Korea or preserve a reconfigurated alliance only with U.S. naval and air presence. or redefine their relationship toward an alliance for stability and interdependence with a token presence of ground forces together with the current level of naval and air forces. The first option of a complete withdrawal of American troops runs the risk of precipitating a power vacuum which is most likely to be filled either by China or Japan. and to trigger Sino-Japanese rivalry and arms race. Should Korea be left alone in the wilderness without an ally, there will arise mounting pressure for developing nuclear weapons in Korea. which could lead to a ''balance of terror." The second option of a reconfigurated alliance with naval and air presence can provide deterrence and reassurance to Korea to a certain degree. However. an alliance without U.S. ground forces cannot guarantee automatic American involvement in the emergency situation that could happen in Korea. In this case. the very credibility of American security commitment will be severely questioned politically. The last option of the alliance with a token U.S. ground force and naval/air forces can be a basis for deterring the rise of hegemonism in Northeast Asia and for preventing Korea from seeking a nuclear option. A small size (3000-5000) of U.S. ground forces in the southern part of Korea. far from the Chinese border. can play an effective hedge against the destabilizing forces and the uncertainty they will bring in Korea. However. this option requires a precondition, which is the Korean people's conviction that the U.S. has contributed to Korea's unification. Otherwise. the revitalizing task of the Korea-U.S. alliance will face insurmountable obstacles.

비포화대 지연배수 효과를 고려한 지하수위 변동모델의 개선 및 적용

김성한,박은규,김용성,김남진,Kim, Seong-Han,Park, Eun-Gyu,Kim, Yong-Sung,Kim, Nam-Jin 한국지하수토양환경학회 2011 지하수토양환경 Vol.16 No.3

Recently, a physically based model of water-table fluctuation due to precipitation is developed based on aquifer water balance model. In the model, it was assumed that the water infiltration into ground surface is advection dominant and immediately reaches to water-table. The assumption may be suited for the sites where the water-table is shallow and/or the permeability of the unsaturated zone is high. However, there are more cases where the model is not directly applicable due to thick and low permeable unsaturated zone. For the low permeability unsaturated zone, the pattern of water flux passing through unsaturated zone is diffusive as well as advective. In this study, to improve the previously developed water-table fluctuation model, we combined the delayed drainage model, which has long been used in well hydraulics, to the water-table fluctuation model. To test the validity of the development, we apply the developed model to 5 different domestic sites. The model parameters are calibrated based on the groundwater hydrograph and the precipitation time series, and the correlation analyses among the parameters are pursued. The overall analyses on the delineated model parameters indicate that the delayed drainage parameters or delay index used in the developed model are able to reveal drainage information in the unsaturated zones.

前漢 武帝는 고조선을 멸망시키고 1년 뒤인 기원전 107년에 沃沮城을 치소로 하여 玄菟郡을 설치하고, (제1현도군), 沃沮와 濊貊 지역을 그 영역으로 했다. 기원전 75년 직전 遼東의 烏桓이 반란을 일으키자, 前漢은 三輔 및 郡國의 불량소년과 죄지은 관리를 징발하여 遼東에 주둔하게 하고 遼東에 玄菟城을 쌓고 현도군을 옮겨와 (제2현도군) 烏桓의 침입에 대비했다. 제2현도군은 토착세력인 句驪가 위치한 지역에 자리했기 때문에 句驪의 이름을 따서 그 지역을 句驪縣이라 하고 郡의 治所로 삼았다. 토착세력인 句驪는 前 漢으로부터 처음에는 縣級인 ‘侯’로 대우받았다가, 桓帝 때 烏桓이 투항하자 그 공로를 인정받아 桓帝의 뒤를 이은 元帝 建昭 2년(B.C. 37)에 郡級인 ‘王’으로 승격된 것으로 보인다. 『三國史記』에서 고구려가 기원전 37년에 건국된 것으로 표방한 것도 이 때문이었을 것이다. 이때 句驪는 前漢으로부터 ‘高’를 姓으로 사여 받아 국호를 句驪에서 高句驪로 변경했을 것이며, 前漢은 高句驪王에게 그 신분에 걸맞게 鼓吹伎人과 朝服을 사여했던 것이다. 이때 玄菟郡의 句驪縣도 高句 驪縣으로 명칭이 변경되어, 전한 말기의 상황을 전하는 『漢書』 地理志에 高句驪로 기재되었던 것이다. 그 뒤 고구려는 新나라를 건국한 王莽이 자신을 징발하여 匈奴를 정벌하려 하자, 기원후 12년 무렵 이에 반항하여 제2현도군의 경계를 벗어나 자립했다. 新나라의 뒤를 이은 後漢은 자립한 高句驪와 관계를 유지하기 위해 ‘王’의 호칭을 인정하고 제2현도군의 동쪽 경계에 幘溝漊라는 작은 城을 쌓아 高句驪로 하여금 歲時에 朝服과 衣幘을 가져가게 했던 것이다. e year after destroying Gojoseon, in 107 BC, Emperor Wu of the Western Han Dynasty, established Hyeondo (Xuantu) Commandery (First Hyeondo Commandery) with Okjeo Fortress as its ruling place, and put Okjeo and Yemaek under its jurisdiction. Shortly before 75 BC, when the Wuhuan of Liaodong revolted, the Western Han drafted delinquent youths and criminal officials from the metropolitan and provincial areas into the army and stationed them in Liaodong. It also relocated Hyeondo Commandery to Liadong (Second Hyeondo Commandery), with the construction of Hyeondo Fortress there to prepare against the invasion of the Wuhuan. As the Second Hyeondo Commandery was located in the area where the Guryeo, the indigenous tribe, resided, the area was named Guryeo County after this tribe and made the ruling place of the commandery. Guryeo was initially treated as a “hu,” which was equivalent to a county, by the Western Han, but as the Wuhuan surrendered during the reign of Emperor Huan, it was promoted to a “wang” (principality) that corresponded to a commandery in recognition of its contribution to the victory in 37 BC (second year of Jianzhao) during the reign of Emperor Yuan who succeeded Emperor Huan. This may be the reason why it is recorded in Samguk Sagi (History of the Three Kingdoms) that Goguryeo was founded in 37 BC. Around this time, the Guryeo was given “Go as their surname from the Western Han and changed their country’s name from Guryeo to Goguryeo, with musicians and performers granted by the emperor in celebration or its elevated status. At this time, the name of Guryeo County in Hyeondo Commandery was also changed to Goguryeo County, which appears in the “Treatise on Geography of the Book of Han that describes the situation of the late Western Han. Then, when Wang Mang, the founder of the Xin Dynasty, tried to subjugate the Xiongnu by mobilizing the people of Goguryeo, it rose up against the policy around 12 AD and became independent outside the boundaries of the Second Hyeondo Commandery. The Later Han Dynasty that succeeded the Xin Dynasty, recognized the title of wang” to maintain relations with the independent Goguryeo, and built a small fortress called Chaekguro Fortress on the eastern border of the Second Hyeondo Commandery where it bestowed o&cial uniforms, clothes and headwears on the people of Goguryeo at special occasions.

한미동맹체제와 주한미군 : 역할 변화의 모색

김성한 한국전략문제연구소 1999 전략연구 Vol.6 No.1

Ⅰ. In 1995, the U.S. Department of Defense published the United States Security Strategy for the East Asian Region, which spelled out the security details for the Clinton Administration's strategy of 'engagement' and 'enlargement' in the East Asian region. The U.S. security strategy for East Asia, enumerated in the EASR, aims at maintaining the leadership role of the U.S. in the region through the four specific measures: 1) revitalizing the alliance with Japan: 2) engaging China: 3) consolidating the alliance with South Korea: and 4) combining bilateralism with multilateralism. The primary means for this strategy is the forward-deployed U.S. forces of about 100,000 in the region. Under the strategic framework, it. is important whether the interests of the U.S. and of Korea converge with each other. One important area where the interests coincide is one in which Korea, for the purpose of survival and the U.S. in order to protect its leadership, need an equilibrium within the region where Korea is located. An hegemonic order in Northeast Asia would threaten the U.S. leadership position as well as the political independence of Korea. Since the equilibrium most conducive to Korea's political autonomy is based on continued U.S. participation in the East Asian security system, Korea will continue to prefer to manage the regional equilibrium in alliance with the U.S. However, the convergence of interests does not always guarantee policy coordination, since Korea and the U.S. can have different policy priorities. This is shown in their North Korea policy. The first priority of the Clinton Administration's North Korea policy lies at the global level where the U.S. deals with North Korea to prevent the spread of weapons of mass destruction to other regions. The second priority is based on the regional level in that the U.S. policy to North Korea is interconnected with its policy of' checking' China. At the level of the Korean peninsula, which is the last priority, the U.S. must reduce the tension between the two Koreas in order to prevent the outbreak of a war on the peninsula and must also seek the ways by which the sudden collapse of North Korea can be successfully managed. On the other hand, Korea's priorities in its North Korea policy are in the reverse order. The Korean government is more concerned with how to harmonize and speed up the progress of improving the relationship of Washington-Pyongyang with that of Seoul-Pyongyang. The problem has been that North Korea has yet to start restoring trust with South Korea, though it has been vigorous in carrying out negotiations with Washington. If the U.S.-North Korea negotiations proceed abreast with the improvement of relations between Seoul and Pyongyang, Korea - U.S. relations will remain smooth, but otherwise, their relations will face various complexities. In this respect, the importance of cooperation between Korea and the U.S. is emphasized. The resolution for the priority divergence between Korea and the U.S. can be achieved through redefinition of the alliance that is to be focused on regional priorities. In other words, both countries need to put their first priority on the strategic interests in Northeast Asia including the Korean peninsula. This is the way by which the global interest of the U.S. and the peninsular interest of Korea can be converged at the regional level. Thus, both countries should emphasize that the Korea-U.S. alliance, that was created to deter North Korea's military threat, will ultimately contribute to stability in Northeast Asia, and that the alliance will continue even after the threat from North Korea disappears. In addition, Korea and the U.S. should start preparing for crisis management in the case of North Korea's collapse. As a measure of redefining the Korea-U.S. alliance, both countries need to announce the "Joint Security Declaration" as soon as Korea's new administration is inaugurated in February 1998. The Declaration will contain the following ideas: 1) The Korea-U.S. alliance is still valid in tills post-Cold War period; 2) Korea and the U.S. will continue to cooperate to induce North Korea to, conduct a gradual reform; 3) The alliance will develop into the 'regional' alliance that will take the role of promoting regional peace and stability in Northeast Asia after Korea's unification. However, both countries should not miss pointing out that Northeast Asian security structure should advance toward multilateralism, since this kind of a joint action could provoke China. After the joint declaration is made, Korea and the U.S. will have to begin consulting each other concerning the necessary steps to transform the alliance into the regional one. A key issue that is to be put on the table will be the role and force structure of the U.S. forces in unified Korea. Ⅱ. Korea and the U.S. will have three options. They have to decide whether they will actually terminate the alliance by completely withdrawing American troops from Korea or preserve a reconfigurated alliance only with U.S. naval and air presence, or redefine their relationship toward an alliance for stability and interdependence with a token presence of ground forces together with the current level of naval and air forces. The first option of a complete withdrawal of American troops runs the risk of precipitating a power vacuum which is most likely to be filled either by China or Japan, and to trigger Sino-Japanese rivalry and arms race. Should Korea be left alone in the wilderness without an ally, there will arise mounting pressure for developing nuclear weapons in Korea, which could lead to a "balance of terror." The second option of a reconfigurated alliance with naval and air presence can provide deterrence and reassurance to Korea to a certain degree. However, an alliance without U.S. ground forces cannot guarantee automatic American involvement in the emergency situation that could happen in Korea. In this case, the very credibility of American security commitment will be severely questioned politically. The last option of the alliance with a token U.S. ground force and naval/air forces can be a basis for deterring the rise of hegemonism in Northeast Asia and for preventing Korea from seeking a nuclear option. A small size (3000-5000) of U.S. ground forces in the southern part of Korea, far from the Chinese border, can play an effective hedge against the destabilizing forces and the uncertainty they will bring in Korea. However, this option requires a precondition, which is the Korean people's conviction that the D.S. has contributed to Korea's unification. Otherwise, the revitalizing task of the Korea-U.S. alliance will face insurmountable obstacles.

QWS-DFB 레이저에서 단일 주파수 동작 안정성을 결정하는 문턱 이득 차이와 축 방향 광자 분포, 균일성을 동시에 나타내는 통합된 설계 변수로서 광자 분포 중심을 정의하고, 이 광자 분포 중심이 문턱 이득 차이와 광자 분포의 균일성과 어떻게 연관되는지를 유효 굴절률 전달 매트릭스 방법으로 보였다. 또, 이로부터 단일 주파수 동작 안정성을 최대화하는 설계 원칙을 제시하였다. 그리고 이 설계 원칙을 적용한 예로서 100% 단일 주파수 동작 수율을 보이는 결합계수의 범위를 넓힌 ,sampled grating QWS-DFB 레이저 구조를 제안하였다. 이 레이저 구조는 단일 주파수 동작을 하는 결합계수의 범위가 좁다는 QWS-DFB 레이저의 문제점을 해결하는 길을 제시하였다. Center of photon mass, defined as the center of axial photon distribution in each half, is proposed as a unified design parameter in quarter wavelength shifted(QWS) DFB lasers. Shown is the way the parameter is related to the threshold pain difference and uniformity in axial photon density, which determine single-frequency stability of DFB lasers. Also, a general rule for single-frequency DFB laser design is presented. Using the design rule, we propose a sampled grating QWS-DFB laser that has a wider $_KL$ range 0f 100% single-frequency yield.

Objective : The purpose of the study was to evaluate the clinical and radiological results after discectomy and Lubboc bone graft in the surgical management of the cervical diseases with a new titanium interbody implant and integrated screw fixation(PCB) by anterior approach. Methods : The authors retrospectively analyzed 28 cases of anterior cervical fusion with PCB system and Lubboc bone(xeno graft) from september 1998 to december 2000. Twenty-eight patients with cervical diseases underwent decompression cervical lesion and followed from 5 to 27 months with a mean follow-up of 14 months. There patients were evaluated with clinically and radiologically at immediate postoperative period and at 3, 6, 9, and 12 months. Result : The authors investigated the pre- and postoperative intervertebral disc space, clinical outcomes, radiography fusion rate, and Cobb angle in the fixed segments by anterior approach. The lordotic angles and height of disc space were increased after the operation. The clinical outcome of patients follow-up was good or excellent result based on Odom's criteria with improvement of clinical symptom in about 92.9% of the cervical diseases. Two patients showed loosening of the lower and upper cervical screw of PCB instruments, and two patients showed swallowing difficulty and wound infection Conclusion : The PCB system is a new implant for anterior cervical interbody fusion in the degenerative cervical disease and disc herniations. It provides immediate stability and segment distraction. The results of this study indicate that the PCB system is safe, easy handling of hardware, less complications, high fusion rate, and has provide the keeping the intervertebral disc space height and lordotic angles.

DFB 레이저의 통합된 설계 변수로서으 광자 분포 중심 I : 저 반사면-고 반사면 구조

김성한,김상배,Kim, Sung-Han,Kim, Sang-Bae 대한전자공학회 1999 電子工學會論文誌, D Vol.d36 No.12

저 반사면-고 반사면 DFB 레이저에서 발전 모드의 문턱이득과 축 방향 광자 분포 균일성을 동시에 나타내는 통합된 설계 변수로서 광자 분포 중심(CPM, conter of photon mass)을 제안하였다. 이러한 통합된 설계 변수가 필요한 것은 발진 모드의 문턱이득과 광자 밀도의 최대값과 최소값의 비, 즉 광자 밀도 비가 서로 독립적이지 않고 깊이 연관되어 있기 때문이다. 제안된 CPM은 발진 모드의 문턱이득과 반비례 관계에 있으며, 그 값이 0.5일 때 축 방향 광자 분포가 가장 균일하다. 또 문턱이득 차이는 주 모드의 CPM과 곁 모드의 CPM은 0.5로 맞추어 광자 분포를 균일하게 하고 곁 모드의 CPM은 최소화하여 주 모드와의 문턱이득 차이를 크게 해야 한다. 이를 위하여는 조절 가능한 회절격자 구조 변수가 더 필요한데 sampled grating이 그 수단으로 제시되었으며, 문턱이득 차이를 증가시키는 데에 사용될 수 있음을 보였다. Center of photon mass(CPM), defined as the center of axial photon distribution, is proposed as a unified design parameter, which contains information about both threshold gain and nonuniformity of axial photon distribution in DFB lasers with low and high-reflection facets. The CPM is inversely proportional to threshold gain and is 0.5 when axial photon distribution is the most uniform. Therefore, a general rule of single-frequency leser design is that main mode CPM should be around 0.5 for-uniform axial photon distribution and side mode CPM should be minimized to maximize the threshold gain difference.

오늘날의 진화론적 논의에서 도덕이 생래적이라는 의미

김성한(Sung Han Kim) 철학연구회 2009 哲學硏究 Vol.0 No.84

In this paper, I argue not only moral capacity is Innate but some emotional factors which are given through Evolutionary process can be found in moral judgments and moral systems. At first, as many people indicate, Morality is different from altruism. But Richard Alexander intends to explain Morality in terms of systems of altruism(nepotism and reciprocity). This should be understood as his attempt to show inner Meaning of Morality. Yet, we can hardly call it successful because genuine altruism can be another characteristic that comprises base of Morality. Meanwhile, it seems that nepotism, reciprocity and genuine altruism cannot explain moral judgment which emphasizes impartiality. This kind of moral judgment seems as a product of reasoning rather than a intuitional emotional response which is influenced by Innate altruism. Even so, we can find biological factors in this kind of moral judgment in that it does not thoroughly exclude nepotism, reciprocity and genuine altruism. Finally, we do not need to suppose the possibility of a particular type of moral ability that controls our moral judgment. We can say we make moral judgment through various abilities that are developed through evolution, and we may call it Innate Morality.

北魏 均田制의 새로운 이해

김성한(Kim Sung-Han) 부산경남사학회 2009 역사와 경계 Vol.70 No.-

Under Jun Tian Zhi in Pei Wei Dynasty, "married men older than 15," not Ding Nan, were qualified for receiving Lu Tian. "Married men older than 15" include not only Ke Kou (taxable persons) between 15 years old and 70 years old, but also Bu Ke Kou (untaxable persons) to whom belong Lao Nan (men older than 71), Du Ji, Fei Ji, and widows. That is, only taxable persons are qualified for Sang Tian and Ma Tian. "Taxable person" refers to men who are married or older than 15. Because men older than 70 are exempted from tax, and because men under 15 can also be classified as taxable if they are married, men between 15 and 70 and married men under 15 are qualified for having Sang Tian and Ma Tian. The heads of Bu Ke Hu (households that are exempted from tax) are Bu Ke Kou (persons free from tax), to whom Sang Tian or Ma Tian is assigned. Under Jun Tian Zhi in Pei Wei Dynasty, men between 15 and 17 and men between 18 and 70 are classified into Ci Ding Nan and Ding Nan, respectively. Both can have estates. As for married women, their qualifications for estates depend on their husbands' status. Widows can hold estates as far as they remain single. Married women can receive Lu Tian and Ma Tian, but not Sang Tian, because high priority, concerning Sang Tian, is given to married men, particularly, in villages that have mulberry plantations. Usually, it needs three years of preparation to grow mulberry trees and rear silkworms. Sang Tien is thus given to single men above 15 who are taxable. Instead, during the period of first three years, their tax rate is reduced to a quarter of usual Zu and Tiao. Male slaves and female slaves are also given equal rights to receive estates in terms of kind and amount of estates. However, there are differences in terms of qualifications for farming land. Both male and female slaves can gain access to estates only when they are classified as taxable. If they want to be classified as taxable, male slaves must engage in farming and female slaves must weave cloth. This condition is equally applied to cattle. According to the regulations of Jun Tian Zhi, Ding Niu (workable cows and oxen) is qualified for farming estates. The laws regulating people's tax, however, specifies the qualification differently, according to which only Geng Niu (Ding Niu that is actually used in farming) can be classified as taxable and thus is given estates.

성매매와 포르노그래피, 어느 쪽이 더 문제인가?

김성한(Kim, Sung-Han) 중앙대학교 중앙철학연구소 2014 철학탐구 Vol.36 No.-

성매매와 포르노그래피는 여러 성 문제 중 가장 논란이 되고 있는 주제들이다. 국내에서는 성매매가 성매매 특별법을 통한 법적인 규제의 대상이 되고 있고, 포르노그래피 또한 제작이 법적으로 금지되어 있지만 이를 보는 것은 거의 일상화되어 있다시피 하다. 이에 따라 사람들은 성매매를 하는 것은 커다란 잘못을 범하는 것이라고 생각함에 반해 포르노를 보는 것에 대해서는 특별히 문제가 없다고 생각하는 편이다. 하지만 양자에 대한 반대 논변들을 검토해 볼 경우 과연 포르노가 성매매에 비해 별다른 문제가 없는지에 대해 의문이 제기될 수 있다. 물론 성매매의 경우는 상대에게 직접적으로 해악을 가함에 반해 포르노는 그렇지 않은 등 실제로 성매매가 더 잘못이라고 생각할 수 있는 문제들이 있다. 하지만 우리가 성 서비스를 제공하는 사람과 제공받는 사람, 그리고 여성 일반에게 가해지는 해악을 나누어서 각각에 관련된 논변들을 비교·검토해 볼 경우 포르노가 성매매 못지않은, 나아가 그 이상의 해악을 미치는 경우도 있음을 확인할 수 있을 것이다. 이 글은 포르노그래피를 흔히 접할 수 있다는 이유로 너무 안이하게 생각하는 태도를 재고하게 하는 데에 그 목적이 있다. Both prostitution and pornography are major objects of controversy among all other sex related issues. In Korea, prostitution is controlled under the special law against prostitution and production of pornography is also forbidden by law, whereas the exposure to pornography has been almost institutionalized. For this reason, although people consider prostitution as a serious crime, they hardly feel guilty about seeing pornography. However, when we review the opposite arguments on both sides, we can question whether pornography can be concerned less than prostitution. Prostitution actually does cause harm to others directly while pornography doesn"t, and there exists more issues we can consider prostitution as a more serious crime but when we compare and review all objections to the criticism made against i) a person who provides a sexual service; ii) a person who accepts a sexual service; and iii) ordinary women respectively, we can recognize that pornography can even cause more harm than prostitution. The purpose of this essay is to reconsider our attitudes of taking pornography too lightly due to its easy accessibility.
