In the oral cavity, the teeth undergo wear and corrosion throughout their lives. Progressive and constant tooth wear is a natural phenomenon of aging, but wear and corrosion due to specific factors are pathological factors. It can cause pathological damage of the occlusal surface, aesthetic problems, dimensional loss and jaw joint disorders. This case is a 26-year-old female patient with general tooth abrasion and erosion on the entire dentition. Diagnostic wax-up was fabricated based on the information including digital facial analysis, physiological stabilization, and evaluation of anterior crown length. Through the digital analysis, the necessary guides for crown lengthening were prepared and the mastication function and esthetics were evaluated by using temporary crowns. Definitive prosthesis was fabricated with the zirconia restorations. The results were satisfactory when they were observed 3 months of follow-up. 구강이라는 특수한 환경 속에서 치아는 평생을 거쳐 마모, 부식 등을 겪게 된다. 점진적이며 일정한 치아의 마모는 노화의 자연스러운 현상이나, 특정 요소에 의한 마모나 부식 등은 병적인 요소이며 교합면의 병리적 손상과 이에 따른 교합 부조화, 심미적 문제, 턱관절 장애 등을 야기할 수 있다. 본 증례는 26세의 젊은 여성 환자로 전반적인 치아의 마모와 부식이 동반된 상태였다. 디지털 안모 분석, 생리적 안정위, 전치부 치관 길이 평가 등을 통해 진단 납형을 제작하였다. 디지털 분석을 통해 치관연장술에 필요한 가이드를 제작하여 수술을 진행하였고 임시 보철물을 통하여 저작 기능 및 심미성을 회복하였다. 지르코니아 최종 보철로 수복하여 심미적, 기능적으로 만족할만한 결과를 얻었으므로 이 증례를 보고하고자 한다.

방역에서 강제와 협조의 조화? - 식민지 시기를 중심으로

박윤재(Park Yunjae) 역사비평사 2020 역사비평 Vol.- No.131

During the colonial period, damage from infectious disease was substantial. Infectious disease was an obstacle to stable ruling of the colony. Police force was at the center of prevention against infectious disease, and as such, it was violent and oppressive. Since disease prevention required forceful measures, a certain extent of coercion was unavoidable, and even effective. A good example is preventive efforts against the plague that took place in the Manchuria in 1910 through 1911. Despite the absence of vaccine or treatment against the plague, not a single person was infected. Problem was that coercion alone was insufficient for efficient prevention of disease. In the 1920s, Korean people resisted preventive measures taken by the colonial government against the cholera, and they sought alternative measures. Specifically, they attempted to establish a Korean hospital that is run by Korean people and applies Korean-style treatment. At the place, both western and Korean traditional medicine could be dispensed depending on a patient’s condition or request. In prevention of infectious disease, Korean traditional medicine was useful in seeking cooperation from the Korean. Choosing either coercion or autonomy is undesirable in making efforts for disease prevention. What is important is to identify an adequate approach depending on specific circumstances. However, it is hard to find a perfect measure that takes into account all factors, and thus, the second-best measure needs to be sought. And one of the ways to do so is to obtain understanding of the society.

때를 밀자 ―식민지시기 목욕 문화의 형성과 때에 대한 인식

박윤재(Park Yunjae) 역사비평사 2021 역사비평 Vol.- No.134

To foreigners that came to Korea with the opening of the ports, Korean people were dirty and smelled bad; they were unclean. Once people realized uncleanliness, they had to pursue cleanliness. And they needed place to wash the body. Hence the bathhouse. Proponents of the enlightenment party―who radically undertook modern reform of the Korean society ―paid attention to the importance of bathhouse. To them, bath was a means of achieving cleanliness and hygiene. Furthermore, it was an instrument for civilization, for modernization. Emphasis on cleanliness and hygiene was made in form of advocating establishment of public bathhouses. Price for public bathhouse had to be low, and thus, many organizations needed to join hands in the endeavor to share cost burden. In some cases, establishment of public bathhouse was proposed as one of missions of youth associations. Since the ancient times, scrubbing off dead skin was a cultural practice of Korean people. With the arrival of modern era, Korean people began to take on this task earnestly. The problem was that Japanese colonization added the sense of inferiority―that Korean people were less clean than Japanese people―to the act of scrubbing off dead skin, which was in realm of cleanliness and hygiene before. Some of the Koreans resisted discrimination from Japanese people, but some took it for granted, saying that unclean people deserved to receive hatred and insult. For them, Koreans were under the ruling of Japan because they were unclean. And dead skin represented uncleanliness. Then, scrubbing off dead skin was an act of overcoming discrimination against Korean people. The logic was that by scrubbing off dead skin, Korean people would be reevaluated as a clean people in the world, a people who can achieve independence eventually.

디지털 포렌식 기법을 통한 기업 정보유출에 대한 취약점 탐지 효율성에 관한 연구

박윤재(Yoon-Jae Park),채명신(Myung-Sin Chae) 한국산학기술학회 2017 한국산학기술학회논문지 Vol.18 No.9

ICT(정보통신기술) 융합보안 환경에서 수많은 기업들이 회사 내에서 생산되는 중요 자료인 제품정보, 제조기술, 서비스 매뉴얼, 마케팅 자료, 홍보자료, 기술적 자료들을 외부공개 및 공유를 위해 웹 시스템을 운영하고 있다. 이렇게 인터넷에 공개된 웹 시스템은 사이버 보안 관리에 매우 큰 영향을 주고 있고, 상시 취약점을 가지고 있어서 정보보호 솔루션과 IT 취약점 점검을 수행하고 있지만, 외부 환경에서의 취약점 탐지 관리에는 한계가 있다. 본 연구에서는 이러한 문제점을 개선하고자, 디지털 포렌식 기반의 시스템을 자체 구축하고 포렌식 기법을 활용하여 기업의 중요정보 유출 탐지에 대한 실증 연구를 수행하였다. 그 결과, 국내와 해외에서 운영하는 웹 시스템의 취약점으로 인하여 기업의 비밀자료 등 중요 정보가 노출된 것을 확인할 수 있었고 보안관리 개선 사항도 확인할 수 있었다. 결론적으로 최근 증가하는 해킹사고 대응으로 디지털 포렌식 기법을 적용한 시스템을 구축한다면 정보보안 취약 영역의 보안관리 강화와 사이버보안 관리체계 개선을 가져올 수 있을 것이다. In the ICT (Information and Communication Technology) convergence security environment, a lot of companies use an external public web system for the external disclosure and sharing of product information, manufacturing technology, service manualsand marketing materials. In this way, the web system disclosed on the Internet is an important aspect of cyber security management and has an always-on vulnerability requiringan information protection solution and IT vulnerability checks. However, there are limits to vulnerability detection management in anexternal environment. In this study, in order to solvethese problems, we constructed a system based on digital forensics and conducted an empirical study on the detection of important information in enterprises by using forensic techniques. It was found thatdue to the vulnerability of web systems operated in Korea and overseas, important information could be revealed,such as the companies" confidential data and security management improvements. In conclusion, if a system using digital forensic techniques is applied in response to theincreasing number of hacking incidents, the security management of vulnerable areas will be strengthened and the cyber security management system will be improved.

해방 후 한의학의 재건과 한의사제도의 성립

박윤재 ( Yun Jae Park ) 연세대학교 국학연구원 2011 동방학지 Vol.154 No.-

국민의료법 논의과정에서 한의학은 논쟁의 중심에 있었다. 보건부가 제헌국회에 제출한 ``의사 및 치과의사법``은 한의사를 배제하였다. 보건부는 한의학이 경험의학이고, 따라서 과학적 의학으로 평가하기 어렵다는 입장이었다. 보건부안이 법률로 채택될 경우 한의학은 사라질 수밖에 없었다. 하지만 한의학을 지지하는 여론에 힘입어 보건부안은 폐기되었고, 대신에 문교사회위원회가 자체적으로 입안한 ``의사 및 의업(醫業)법``이 상정되었다. 한의사들은 이 안이 한의사를 포함하고 있는 점에서는 평가를 하였지만, 자신들을 서양의사와 동등한 의료인으로 인정하지 않는 점에 대해서는 불만을 토로하였다. 제2대 국회로 이월된 의료법 논의에서 한의학의 과학성 여부는 다시 토론의 핵심이 되었다. 비판자들에게 한의학은 서양의학의 기초 분야를 포함하지 않은 비과학적 의학이었다. 하지만 반대 의견 역시 강했다. 수천 년을 이어진 한의학의 역사가 거론되었고, 일제의 탄압 대상이었던 만큼 민족 부활의 상징으로 발전시켜야 한다는 주장이 제기되었다. 한의학의 실용성도 지목되었다. 한약은 국가와 국민 경제에 이익이 될 수 있다는 것이었다. 그러나 한의학에 가장 우호적인 요인은 부족한 의료현실이었다. 서양의사들이 대도시를 중심으로 개업하고 있고, 한의사들이 농촌지역의 주요 의료인력으로 활동하고 있는 현실은 한의학에 우호적인 여론을 낳는 배경이 되었다. 무의촌 해결이 가장 중요한 의료문제로 대두되는 상황에서, 더욱이 국회의원들이 자신의 지역 이해를 대변할 수밖에 없는 상황에서, 한의학 배제는 추진하기 힘든 시도였다. 결국 제2대 국회는 1951년 의사와 치과의사를 제1종, 한의사를 제2종, 보건원, 조산원, 간호원을 제3종 의료업자로 나눈 국민의료법을 통과시켰다. In the process of forming the National Medical Act, at the heart of the debate was Oriental Medicine. "The Medical Doctor and Dentist Law" presented by the Department of Health to the National Assembly denied the professional legitimacy of Oriental medical practitioners. The Department of Health was critical of Oriental Medicine, believing it to be empirical medicine; thus, Oriental Medicine struggled to be seen as scientific medicine. Had the plan of the Department of Health been adopted, Oriental Medicine would have disappeared. However, the plan of the Department of Health failed due to public opinion supporting Oriental Medicine, and instead of the plan, the Educational Affairs and Society subcommittee submitted "the Medical Doctor and the Medical Profession Law," which they had drafted autonomously. Oriental medical practitioners welcomed the latter plan because it included them, but they also complained that it did not recognize them as health care providers on par with Western medical practitioners. In the debate over the National Medical Act, which progressed on to the second National Assembly, at the heart of the discussion was whether or not Oriental Medicine was scientific. For critics, Oriental Medicine was unscientific medicine that did not include the basics of Western medical science. However, opposing views were also strong. Supporters of Oriental Medicine drew attention to its thousands-year-old history, some suggesting that because Oriental Medicine had been an object of oppression under Japanese rule, it had to be developed as the symbol of national resurrection. The practicality of Oriental Medicine was also mentioned, as herbal medicine could serve to the benefit of the national economy. However, the poor medical service environment was the most favorable factor for the continuation of Oriental Medicine. The reality that Western medical practitioners were practicing medicine in big cities like Seoul, leaving Oriental medical practitioners to treat people as the main medical human resources in agricultural districts, made public opinion to be in favor of Oriental Medicine. As decreasing the number of doctorless villages was emerging as the most urgent medical issue, and moreover as most congressmen had to represent the interests of the electorate, it was impossible to eliminate Oriental Medicine. Ultimately, the second National Assembly passed the National Medical Act in 1951, which presented Western medical practitioners and dentists with a Type 1 license; Oriental medical practitioners with Type 2; and health nurses, midwives and nurses with Type 3.

일제의 한의학 정책과 조선 지배

박윤재(PARK Yunjae) 大韓醫史學會 2008 醫史學 Vol.17 No.1

During its colonization of Korea, the Japanese Empire used the Western medicine as a tool for advertising its advanced culture. However, the medical workforce available in Korea was insufficient. The Rule for Uisaeng(Oriental medicine practitioner) was an ordinance decreed in 1913 with a purpose of supplementing the medical workforce. As the Oriental medicine practitioners became official medical workforce, the Japanese Empire could mobilize them in a hygienic administration such as prevention of epidemics. The Uisaengs also tried to adapt themselves to the colonial environment by studying Western medicines. However, the distrust of the Japanese Empire in Oriental medicine continued until 1920s. Manchurian Incident in 1931 brought a change. As the relationship with China aggravated, the provision of medical herb became unstable and the Japanese Empire began to encourage using Oriental medical herb following the Movement for Improving Rural Region Economy. An attempt of the Japanese Empire to utilize the medical herb resulted in a plan to make the Oriental medical herb officinal. The goal was to organize and standardize the Oriental medical herb through a research by the Medical Herb Investigation Committee. However, the medical herb on the table was the one verified by the Western medicine. That is, it was not a traditional medical herb that uses the original theory of Oriental medicine. There was a minority opinion arguing that they should study the Oriental medicine itself. However, that argument was also based on the theory and principles of the Western medicine. Even though an attempt to make full use of Uisaengs expanded as the war continued, the major medical workforce that the Japanese Empire relied on was those trained in Western medicine. In other words, the Japanese Empire did not give a full credit to the Oriental medicine during the colonial era. During the colonization, Japanese Empire used Oriental medicine under the nominal reason of lack of medical workforces. In early 1930s, a policy supporting usage of Oriental medical herb was selected. However, it does not mean that the change in policy encouraged Oriental medicine since the medical herb that the Japanese Empire supported was those that were organized and categorized according to the principles in Western medicine.
