Chronic Prostatitis: Approaches for Best Management
이경섭,최재덕 대한비뇨의학회 2012 Investigative and Clinical Urology Vol.53 No.2
Prostatitis is a prevalent condition that encompasses a large array of clinical symptoms with significant impacts on men’s life. The diagnosis and treatment of this disorder presents numerous challenges for urologists, most notably, a lack of specific and effective diagnostic methods. Chronic bacterial prostatitis is successfully treated with appropriate antibiotics that penetrate the prostate and kill the causative organisms. Prostatitis category III (chronic pelvic pain syndrome) is common, very bothersome, and enigmatic. Symptoms are usually prolonged and, generally speaking, treatment results are unsatisfactory. During the last decade, research has focused on the distress caused by the condition, but although our knowledge has certainly increased, there have been no real breakthroughs; controversies and many unanswered questions remain. Furthermore, the optimal management of category III prostatitis is not known. Conventional prolonged courses of antibiotic therapy have not proven to be efficacious. Novel therapies providing some evidence for efficacy include alpha-blocker, anti-inflammatory phytotherapy, physiotherapy, neuroleptics, and others, each offering therapeutic mechanisms. A stepwise approach involving multimodal therapy is often successful for treating patients. The UPOINT technique has been used to clinically phenotype these patients and drive the appropriate selection of multimodal therapy.
센서개발을 위한 Langmuir膜의 相轉移에 關한 硏究

In this paper, we observed and theoritically analyed the mechanism of the displacement current for stimulation transmit by the displacement current measurement method. And the orientational change of molecules in monolayers was discussed on the basis of the Maxwell-displacement-current obtained. It was known that Maxwell displacement current was generated for monolayers on the water surface by compression. Therefore, we applied to the study of monolayers of Dipalmitoylphosphatidyl choline (L -α- DPPC). As results,the displacement was generated when the area per molecule about 180Ų in low pressure, and it was generated when the area per molecule about 110Ų in high pressure. Finally,we measured the differential thermal analysis(DTA) of sample. Phase transition was showed at 124.6℃ by DTA.

Purpose: The authors evaluated the possibility of protein C and protein S as risk factors for retinal vein occlusion (RVO). Methods: We evaluated the medical histories and performed laboratory tests, including protein C and protein S, in patients who were diagnosed with RVO by fundus examination and fluorescein angiography. The same data were obtained from a healthy control group. We analyzed mean activity and the ratio of patients with decreased levels of protein C or protein S. Results: Forty-seven patients with RVO in this study consisted of 14 with central retinal vein occlusion (CRVO) and 33 with branch retinal vein occlusion (BRVO). Sixteen normal subjects were also enrolled in this study as controls. There are no cases that presented decreased protein C activity. However, there was a statistically significant difference in the number of cases with protein S deficiency between the patients and the control group (p<0.05). Conclusions: Deficiency of anticoagulant proteins, especially protein S, may be a risk factor of retinal vein occlusion. Examination of the coagulation system may be useful in the systemic evaluation of RVO patients.

탄소당량과 흑연형상에 따른 주철과 ADI 의 기계적 성질에 미치는 수소의 영향
이경섭,조용기 한국부식학회 1989 Corrosion Science and Technology Vol.18 No.1
The effect of hydrogen on the mechanical properties of cast irons, flake, CV graphite cast iron ductile iron and ADI have been investigated. The effects of various carbon equivalent, graphite morphology and matrix have been analyzed to determine the predominant factor which influences on the hydrogen embrittlement. The effect of various carbon equivalent on the embrittlement was little in the similar graphite morphology. The embrittlement of ferrite matrix changed by heat treatment was less than that of pearlite matrix. In the case of ADI, the tendency of hydrogen embrittlement of lower bainite matrix was less remarkable than that of upper banite matrix. As the result of hydrogen charging, the tendency of interface decohesion between matrix-graphite was increased in flake G.C.L, and the trend from ductile fracture mode to brittle fracture mode was observed in CV G.C.I and ductile iron. Lower bainite in ADI showed the ductile fracture mode. Hydrogen solubility of lower bainite was higher than that of upper bainite.
