김낙인,조항래,김형섭 대한의진균학회 1996 대한의진균학회지 Vol.1 No.1

Cutaneous ulcers due to candida infection are very rare condition, occurring almost in immunocompromised host or occuring as cutaneous manifestation of systemic candidal infection. A 52-year-old woman presented with cutaneous ulcer on dorsum of left hand which had lasted for about 15 days. Bacterial culture showed nonpathogenic organism, Enterobacter cloacae. Mycologic studies including KOH mount and fungus culture were positive for pseudohyphae and colonies of Candida species. A biopsy specimen from the center of ulcer revealed numerous spores and fungal hyphae in the upper dermis and necrotic epidermis. Bacterial culture and fungus culture of patient's serum and urine were negative. Initial treatment with antibiotics had no effectiveness for 2 weeks. After then we treated with antifungal drug, itraconazole 100mg/day. After 6 weeks of antifungal therapy, the skin lesion was much improved. We report this case, because it showed cutaneous ulcer due to candida infection but had neither systemic candidal infection nor clinical sign of immunosuppression.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Hang Seob Yoon,최우진,성일훈,Ho Seong Lee,정형진,이진우 대한정형외과학회 2013 Clinics in Orthopedic Surgery Vol.5 No.2

Background: This study evaluated the effects of Beraprost sodium (Berasil) on subjective leg symptoms in patients with peripheral arterial disease caused by diabetes mellitus. Methods: Ninety-four diabetic patients with peripheral arterial disease were treated with Beraprost in a fixed-dose, prospective, multicenter, cohort study. Beraprost (40 μg) was administered orally 3 times daily (120 μg/day) for 12 weeks. We developed a new disease-specific symptom questionnaire, which evaluated the effect of peripheral arterial disease on leg discomfort in daily life and assessed therapeutic responses to treatment. Patients were asked for their subjective assessment of symptoms on a written questionnaire before treatment and after 12 weeks of therapy. Results: There was significant improvement in all estimated subjective symptoms (burning, coldness, edema, exertional pain, stabbing, and paresthesias) in the lower extremities at 12 weeks (p < 0.001). There were 18 patients with neuropathy in whom significant improvement was noted for 6 subjective symptoms at 12 weeks (p < 0.05). Adverse events considered to be drug-related were observed in 4 patients (4.3%), all of which were mild and resolved with discontinuation of the medication. Conclusions: Beraprost is effective as a treatment for improving various subjective symptoms in the lower extremities, such as burning, coldness, edema, exertional pain, stabbing, and paresthesias, in diabetic patients with peripheral arterial disease.

Popular Movements and Violence in East Asia in the Nineteenth Century: Comparing the Ideological Foundations of their Legitimation

( Hang-seob Bae ) 성균관대학교 동아시아학술원 2017 Sungkyun Journal of East Asian Studies Vol.17 No.2

In the nineteenth century, people in China, Korea, and Japan actively participated in popular protests. The rebellions in those countries had much in common, but one of the most striking differences is the degree of violence inflicted by these popular movements on their opponents. Chinese popular rebels were much more likely to kill or injure others than their counterparts in Korea and Japan. Such differences seem to be closely associated with the question of whether the rebel forces fought due to conflicting interests within the polity, or were seeking to build a new kingdom by pursuing a newly-risen religion while rejecting the existing ruling system and ideology that legitimized it. This paper will examine how the rebel forces based the legitimacy of their actions in relation to each country’s “political culture.” While popular movements in the West or the Taiping Heavenly Kingdom were based on the idea that God was more powerful than the secular ruler, popular movements in Korea or Japan did not have a transcendent source of authority that was superior to the monarch. This paper argues that this made a crucial difference to how people thought and behaved, influencing the degree of violence they employed.

Growth and Characteristics of Near-UV LED Structures on Wet-etched Patterned Sapphire Substrate

Hung-Seob Cheong,Chang-Hee Hong 대한전자공학회 2006 Journal of semiconductor technology and science Vol.6 No.3

Patterned sapphire substrates (PSS) were fabricated by a simple wet etching process with SiO₂ stripe masks and a mixed solution of H₂SO₄ and H₃PO₄. GaN layers were epitaxially grown on the PSS under the optimized 2-step growth condition of metalorganic vapor deposition. During the 1st growth step, GaN layers with triangular cross sections were grown on the selected area of the surface of the PSS, and in the 2nd growth step, the GaN layers were laterally grown and coalesced with neighboring GaN layers. The density of threading dislocations on the surface of the coalesced GaN layer was 2~4 × 10? ㎝?² over the entire region. The epitaxial structure of near-UV light emitting diode (LED) was grown over the GaN layers on the PSS. The internal quantum efficiency and the extraction efficiency of the LED structure grown on the PSS were remarkably increased when compared to the conventional LED structure grown on the flat sapphire substrate. The reduction in TD density and the decrease in the number of times of total internal reflections of the light flux are mainly attributed due to high level of scattering on the PSS.

브라질 가톨릭 운동과 해방신학의 기원

김항섭(Hang-Seob Kim) 한신대학교 신학사상연구소 2019 신학사상 Vol.0 No.187

이 글은 해방신학의 기원을 1950, 60년대의 브라질 가톨릭 운동의 맥락에서 살펴보고자 한다. 브라질의 가톨릭 운동은 근대 세계에서 가톨릭의 영향력을 복원하려는 제도적 필요성에 의해 제창된 가톨릭 액션에서 출발하지만, 1950년대에서 브라질의 현실과 만나면서 급진화 과정을 거쳐, 50년대 말과 60년대 초반에 마르크스주의를 수용하면서 가톨릭 좌파로 발전한다. 그리고 이 운동들은 군부 정권의 탄압과 보수적인 교계의 외면으로 60년대 후반에 이르러 쇠락의 길을 걷지만, 브라질 사회와 가톨릭교회에 남긴 발자취는 뚜렷하다. 무엇보다도 해방신학을 비롯한 진보적인 교회 흐름을 정초하는데 큰 기여를 했다. 두 운동 사이의 연계는 인적 차원이나 이념적 차원에 잘 드러난다. 특히 가난한 이들을 위한 선택과 연대, 가톨릭의 사회적 가르침에 대한 충실성, 구조적 접근을 통한 변혁적 전망, 반자본주의적 태도, 서구 신학에 대한 비판 등에서, 이후 해방신학에 나타나는 주요한 특성을 잘 보여주고 있다. 이러한 맥락에서 보았을 때 브라질 가톨릭교회의 진보적인 전환은 해방신학이 아니라, 그보다 앞서 이뤄졌던 가톨릭 운동에서 시작되었고, 그러한 실천적 계기들이 신학적으로 종합되고 체계화되면서 해방신학이 태동한 것으로 볼 수 있다. This article examines the origins of liberation theology in the context of the Brazilian Catholic movement of the 1950s and ‘60s. The Catholic movement in Brazil was started as Catholic Action, promoted by the institutional necessity to restore Catholic influence in the modern world. But in the 1950s, this movement was radicalized and evolved into the Catholic left and embraced Marxism in the late fifties and early sixties of Brazil in an effort to respond to its context. And these movements were on the decline in the late sixties due to the oppression of the military regime and the conservative hierarchies, but their footprints left in Brazilian society and the Catholic Church are evident. Above all, it contributed to the foundation of a progressive church movement and Liberation Theology. The link between the two movements is well represented on the human and ideological levels. Especially in the solidarity with the poor, the fidelity to Catholic social teaching, the transformational outlook through a structural approach, the anti-capitalist attitude, and the criticism of Western theology, this progressive movement anticipates the major features of later Liberation Theology. In this context, the progressive transformation of the Brazilian Catholic Church does not begin with Liberation Theology. It started with the Catholic movement that preceded this theology. Liberation Theology was born as such practical intuitions were synthesized and organized theologically.
