Letters to the Editor : Computer-aided proximal caries diagnosis correlation with clinical examination and histology

Kang, Byung-Cheol,Scheetz, James P.,Farman, Allan G. 大韓口腔顎顔面 放射線學會 2003 Imaging Science in Dentistry Vol.33 No.4

We are writing this letter to correct misimpressions that could arise from a paper your journal recently published concerning Logocon Caries Detector (LCD). Kang et al reported a relatively poor performance for LCD as compared to other studies. However, when compared to the performance of the imdependent team of dentists who evaluated the same tooth surfaces visually without using LCD, one get a much different impression of LCD. Table 1 show the comparison. These visual results were collected as a part of Dr. Kang's study at the University of Louisville School of Dentistry and were included in the draft manuscript, but were unfortunately omitted from the final paper without the knowledge of two of the listed co-authors(AGF and JPS).

단무지 공장에서 발생한 질식 사고의 원인과 방사선학적 소견: 중례보고 및 가스분석 결과

박충기,김만구,김흥철,안범규,박만수,황우철,최철순,강익원 江原大學校 附設 環境硏究所 1994 環境硏究 Vol.11 No.-

목 적:단무지 공장에서 질식사고를 일으켰던 가스의 종류를 알아내고, 이러한 가스중독의 방서선학적 소견을 소개하기 위하여 본 연구를 하였다. 대상 및 방법:단무지 공장에서 발생한 질식 사고자 3예중 생존자 1예를 대상으로 단순흥부X-선검사와 CT 소견을 분석하였으며, 가스의 종류를 알아내기 위하여 단무지를 유리병에 넣어 발생된 가스를 가스크로마토그래픽을 이용하여 분석하였다. 결 과:단무지 공장에서 발생한 질식사고자중 생존한 1명의 방사선학적 검사에서 신속히 호전되는 폐경결(consolidation)을 볼 수 있었으며 이는 폐부종의 소견임을 알 수 있었다. 협기성 상태에서 단무지를 담은 유리병의 상층부 가스를 실험 분석한 결과 이산화탄소, 에칠알코올이 다량으로 검출되었으나 독성가스는 주로 황화수소이였다. 결 론:단무지 공장의 질식 사고자에서 폐방사선학적 소견은 폐경결을 보이는 폐부증으로서 이는 실험을 통해 단무지에서 발생되는 유독가스인 황화수소 때문임을 입증하였다. Purpose: To identify the main toxic gas released from salted radish in rice bran(Dan-M-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. Materials and Methods: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. Results: The radiographlc examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headapace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. Conclusion: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

公園에서의 利用者 破壞行爲와 管理改善方案에 關한 硏究

姜喆基 順天大學校 1993 論文集 人文社會科學篇 Vol.12 No.-

Vandalism is definded as any act that willfully defaces or destroys some parts of an outdoor recreation area, resulting increased costs to the manager or lessening the appeal of the area to the visitor. This study was proposed to arrive at effective-preventive techniques of vandalism in parks. In this study, the understanding of the different types of motives that underlie vandalism was needed. And I found that much depreciative behavior in parks in preventable, that costly deliberate vandalism can sometimes be circumvented. To make the park more humanistic, I think, park designers and managers must to exert their best efforts to prevent vandalism in parks.

This study was performed to determine the seroprevalence of EBV infection in young adults of South Korea. A total of 196 subjects were enrolled for the analysis of EBV seroprevalence. All subjects were males and their median age was 21 years old (range, 19-24 years). The overall anti-VCA IgG seropositivity prevalence was 87.2% (171/196). This result suggests that approximately 10% of young adults belongs to the risk group of infectious mononucleosis, even in South Korea that has been known as a highly seroprevalent country.

경계성 인격 장애 환자의 정신치료 상황에서의 거리문제

강철중,박숙현 부산대학교 병원 암연구소 2006 부산대병원학술지 Vol.- No.20

From the first contact between therapist and patient, establishing optimal distance is a high priority. Borderline patients repeatedly test the professional boundaries of the relationship and often directly or indirectly express a wish for a parent rather than a therapist. Early in the psychotherapy process, the therapist often feels a sense of floundering and an inner urgency to act rather than reflect. Because of the potential for pharmacotherapy to be contaminated by countertransference responses, a rational and systematic approach to medication, based on target symptoms and trait vulnerabilities, must be part of the overall treatment plan. Establishing a therapeutic frame and a contractual understanding is a useful way to construct an analytic space with the patient in which psychotherapy can take place. Matters such as fee payment, the length of sessions, the handling of vacations, the frequency of sessions, the need for psychiatric hospitalization, the management of suicidal crises, and a policy on phone calls should be part of this contract. On the other hand, a good deal of countertransference enactment can hide behind the rigid adherence to an inflexible structure. The balance between flexibility and boundaries parallels the therapist’s oscillation between playing the role of a new object in the present and an old object from the past.

Objetives : In order to provide useful data tbr the further clinical studies with Korean alcohol-dependent patients, enrollment and non-relapse rates were investigated while alcohol-dependent patients wcre followed up for 24 weeks. Methods : The subjects of this study were alcohol-dependent male patients who, for the first time, visited a hospital among 3 groups of hospitals, University Hospital, General Hospital or Mental Hospital, or those who needed to be followed up after discharge from those hospitals. After assigning 12 subjects to each hospital, we investigated enrollment and non-relapse rates while cognitive-behavioral therapy and pharmacotherapy were provided. Results : 1) Forty-eight patients were enrolled and the rate of enrollment was 36.4%. The enrollment rate in the University Hospital group was 52.1%, in the General Hospital group 50.0%. and in the Mental Hospital group 10.4%. 2) In 48 patients, non-relapse rate was 27.1% at 12 week and 18.8% at 24 weeks after starting follow-up. It was 24.4% and 20.0% at 12 and 24 weeks, repectively, in the University Hospital group while the General Hospital group showed 33.3% and 16.7%, respectively, and the Mental Hospital Group showed 20.0% at both 12 and 24 weeks. Conclusion : These results provide important data for further clinical studies of Korean alcohol-dependent patients.

대기업의 경제력집중에 대한 한일 양국의 인식

강철구 培材大學校 社會科學硏究所 2012 사회과학연구 Vol.34 No.1

Lately, concentration of economic power by big business groups has become a issue in Korea. It occurs from the differences in views and interpretations from the politicians, the public, and the Big Business Groups. This leads to being sensitive to the stream of societies rather than being based on objective facts, resulting with distrust in the economic structure and political system, allowing social cost to occur. In comparison, in Japan there is the history of planning to achieve economic democracy through the process of the General Headquarters(GHQ) breaking up businesses and dismantling the Zaibatsu headquarters after the 1945. However, it must be recognized that after its dismantlement, the Zaibatsu Headquarters has ultimately contributed to Japan’s economic growth with changed names ‘Japan’s Business Group’ or ‘Keiretsu’. Therefore, by comparing the business groups between Korea and Japan, this research examines what influences the business group has on the state’s economy in the rapid economic growth period. Furthermore, it was also examined how the differences of viewpoints between Korea and Japan concerning concentration of economic power were formed and if optimal corporate governance exists. This resulted in the conclusion that the ownership structure and corporate governance in Korea’s big business groups must ultimately settle as the Korean model of corporate governance.

電子文書交換方式(EDI)의 法律的 問題

姜元辰,金喆浩 釜山 大學校 經營 經濟 硏究所 1996 經營 經濟 硏究 Vol.15 No.1

電子文書交換方式(EDI)을 이용하여 貿易去來를 하는 경우에는 經濟的으로나 業務의 能率面에서 그 유용성이 매우 크다고 할 수 있다. 그러나 EDI는 전통적인 종이서류에 의한 거래에 비하여 法律的 側面에서 여러 가지 문제점들을 야기시킬 가능성이 존재한다. 즉, 첫째 EDI의 이용에 따라 전자문서가 사용되어지는 경우에 電子文書의 認證問題, 둘째 전자문선의 法廷에서의 證據能力問題, 셋째 EDI에 의하여 계약이 체결되는 경우 계약성립과 관련된 문제, 넷째 EDI의 이용에 따른 전자문서상의 資料保護問題, 다섯째 EDI의 이용당사자간의 책임분담문제 등이 발생할 수 있다. 따라서 이러한 法律的인 問題點들이 해결된다면 EDI의 이용은 더욱 크게 확대될 것이다. 따라서 貿易業務自動化가 효율적으로 추진되기 위해서는 EDI의 前提條件으로 通信과 書類에 대한 法的 效力 및 證據能力의 認定과 標準化가 필요하며 또한 모든 貿易情報의 保安이 요구된다. 이러한 제반 문제에 관한 법적 ·제도적 장치로서 우리 나라에서는 貿易業務自動化促進에 관한 法律에 그 근거를 마련하고 있고 있으나, 국제적으로는 EDI에 대한 通一法規가 존재하지 않은 실정이다. 한편 UN은 國際전자문서교환방식標準으로서 유엔 행정ㆍ상업ㆍ운송에 관한 전자문서교환방식(UN/EDIFACT)를 제정하여 컴퓨터간에 교환되는 전자문서의 구성 및 그 내용에 관한 標準化 뿐만 아니라 EDI의 通信方法 등이 標準化 및 코드화 작업을 추진하고 있다. 따라서 향후 무역거래에 있어서 EDI를 성공적으로 실행하기 위해서는 UN/EDIFACT를 중심으로 국제적인 EDI표준이 통일화되어야 할 것이다.
