Yoon,Myong-O,Park,Jin-Kook,Kim,Choong-Ik,Ryou,Hong-Sun,Kim,Jin-Gon,Kim,Myung-Bae,Choi,Jun-Seok,Kim,Kwang-Il 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-

Fire characteristics of a typical apartment building in Korea was studied through full scale experiment and zone model simulation. The fire was ignited at the living room and allowed to spread to other parts of a single unit in a five storied apartment building. Various data including temperatures, species concentrations, and images were collected in the experiment. A zone model(CFAST) was used to analyze the same apartment building that represents the average households in Korea. The results were compared with a full scale experiments. While CFAST allows one compartment involved with fire, the experiment allowed the fire to spread to other compartments. Therefore, the comparison between experimental data and Zone-Model data is valid until the living-room fire spread to other parts of the apartment. Flashover occurred at approximately 380 seconds in a fire experiment, and at approximately 420 seconds in Zone-Model. Based on all of data between experimental data and Zone-Model data, it is concluded that the safe escape time is about 250 seconds.

윤진상,최호일 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

본 연구는 외상성손상이나 신체질환으로 인해 사지절단을 받은 32명의 환자들에서 판탐지현상(phantom limbphenomenon : PLP) 및 이와 관련된 임상특성 그리고 이들의 정신의학적 특성을 조사하였다. 정신병리적 상태로서 불안, 우울, 통증의 정도를 PLP의 출현유무에 따라 출현군(PLP군)과 비출혈군(absence of PLP group : APLP)간에 비교하였으며, 또한 PLP군에서 통증의 동반 유무에 따라 통증군(painful PLP group : P-PLP군)과 비통증군(non-painful PLP group : N-PLP군)간에 비교하였다. 조사는 수술 3일, 7일 및 30일째에 반구조적인 면접과 자기보고형척도를 통하여 이루어졌으며 다음과 같은 결과를 얻었다. 1) 32명의 사지절단 환자 중 27명(84%)에서 PLP를 경험하였으며, 이들 중 26명(96%)이 수술 후 3일 이내에 나타났다. PLP가 일단 출현하였던 27명 가운데 17명(70%)은 본 연구의 마지막 조사시점인 수술 후 30일 째에도 PLP가 지속되었다. PLP군에서 운동감각은 18명(67%), telescopy는 11명(40%), 절단된 사지와 관련된 꿈은 6명(22%), 판탐통은 20명(74%)에서 각각 출현했다. 2) 20명의 P-PLP환자에서, 14명(70%)이 수술 후 3일 이내에 나타났다. P-PLP가 일단 출현하였던 20명 가운데 13명(65%)은 본 연구의 마지막 조사시점인 30일 째에도 P-PLP가 지속되었다. 3) 판탐통의 형태로는 사지절단 환자들 사이에서 다양했다. 그러나 그 중 전기가 흐르듯 찌릇찌릇한 통증이 가장 많았다. 판탐통은 절단단부를 만지거나 무엇이 가까이 접근할 때가 가장 심해졌으며, 관심을 다른 방향으로 돌릴 때가 가장 완화되었다. 4) 불안, 우울, 통증의 척도점수는 PLP군이 APLP군보다 또한 P-PLP군이 N-PLP군보다 유의하게 높았다. 본 연구의 결과를 종합 해석하면, PLP의 출현율 및 이와 관련된 임상특성은 외국의 연구와 유사한 결과를 보였다. 사지절단 환자의 정신병리적 상태는 PLP가 출현한 환자에서 특히 통증을 동반한 환자에서 심하여서 이들에게는 정신의학적 중재의 필요성을 시사하였다. Objects : Phantom limb phenomenon(PLP) is characterized by a sensation of persistence of the limb even after its removal. Limb amputation itself give rise to serious functional, social and psychological problems. The aim of this study was to evaluate clinical and psychiatric characteristics of PLP. Methods : This was a prospective study of 32 patients who had undergone limb amputation due to traumatic injuries and physical diseases. The researchers had semi-structured interview with patients at 3 days, 7 days and 30 days after operation in order to obtain information about PLP and its related clinical characteristics. At the same time self-rating scales for state anxiety(Spielberger et al 1970), depression (Beck 1961) an pain and distress(Zung 1983) were administered to patients and then these psychopathological states compared between groups of patients[patients with PLP vs. those without PLP(APLP) and patients with painful PLP(P-PLP) vs. those with non-painful PLP(N-PLP)]. Results : 1) Among 32 amputees, 27(84%) experience PLP. 26(96%) cases out of these appeared within 3 days after amputation. In 17(70%) cases the PLP lasted till the time of the 30th day after amputation. The incidences of feeling of movement, telescopy, appearance of dream and pain in the PLP group were 18(66%), 11(40%), 6(22%) and 20(74%) respectively. 2) Of 20 patients with P-PLP, 14(70%) cases experienced the pain within 3 days after amputation. In 13(65%) cases the pain lasted till the time of the 30th day after amputation. 3) The types of phantom pain varied considerably among amputees. However, electric current sensation was most commonly reported after amputation. Phantom pain was often aggravated by touch or approach of stump but, relieved by distraction. 4) The scores of rating scales for anxiety, depression and pain and distress were significantly higher in PLP group than APLP group and also significantly higher in P-PLP group than N-PLP group. Conclusions : The incidence of PLP and its related clinical characteristics are similar to the studies reported by others. The psychopathological states of the amputees suggest that psychiatric intervention is required particularly for those with PLP but more for those with P-PLP.

윤양웅,최정내,김진권 원광대학교 2001 論文集 Vol.26 No.-

논문에서는 공정동조를 위한 새로운 방법을 제시한다. 미지의 동특성을 가지는 공정은 PID 제어기를 적용하기 위해 2차 전달함수로 모델링된다. 우선 오버슈트(os), 정정시간 (ts), 정상상태 값 (yss)가 미지공정의 스텝응답으로부터 얻어지고, 위의 세가지의 파라메터를 이용하여, 전달함수를 얻을수 있다. 제안된 동조방법의 우수성을 보이기 위해 다른 동조방법들과 시뮬레이션을 통하여 비교하여 제시하였다. In this paper, a new method for system identification is proposed. Unknown dynamic system is identified to the second order transfer function, which can be applied to PID controller design. First, overshoot(os), settling time(ts), and steady state value(yss) are obtained from the step response of unknown dynamic system. And then, we can get the second order transfer function using equations which are extracted from those three parameters(os, ts, yss) through mathmatical analysis. In addition, simulation is carried out to show excellent performance of proposed identification method compare with other.

성견에서 교정적 고정원으로서의 티타늄 미니스크류에 대한 연구 : An experimental investigation in dogs

윤병수,최병호,이원유,김경남,심형보,박진형 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.5

교정치료에서 원하는 치아이동을 위해서는 안정된 고정원이 필요한데 티타늄 미니스크류가 매식과 제거가 쉽고, 구강 내 여러 부위에서 적용이 가능하고, 환자가 느끼는 불편감이나 비용적인 부담이 적고, 제거 후에 치유가 빠르게 진행될 수 있는 등의 장점이 있어 최근에 교정적 고정원으로 사용되기 시작하였다. 티타늄 미니스크류를 교정적 고정원으로 사용한 임상 예들이 여러 편 발표되었는데 미니스크류의 이완이 가장 큰 실패의 원인으로 보고되고 있다. 그러나 지금까지 보고된 논문들에서 교정적 고정원으로 안정성을 줄 수 있는 스크류의 식립 길이에 관한 연구가 없는 상태이다. 교정적 고정원으로 미니스크류를 효과적으로 사용하기 위해서는 식립 부위에 따른 골구조와 골밀도 차이를 고려한 식립 길이에 관한 기준이 필요하다. 이에 본 연구에서는 성견의 상악골과 하악골에서 직경 2mm 티타늄 미니스크류를 다양한 길이로 식립하고 교정력을 적용한 후 그 안정성을 평가하여 교정적 고정원으로 사용될 수 있는 미니스크류의 식립 길이를 결정하고자 하였다. 미니스크류가 상악에서는 6mm이상, 하악에서는 4mm 이상이 골 내에 식립될 때 8주 동안 200g의 교정력에 동요도나 위치변화를 보이지 않았다. 식립 부위로는 부착치은 부위 치근 사이에 식립될 때 구강청결이 유지되고 미니스크류 주변 치은조직에 자극을 주지 않아 정상적인 조직으로 유지 될 수 있었다. 또한 교정력 적용 8주 후 치근단 방사선 사진검사에서 스크류 주변 치근 흡수나 치조골 흡수, 치주 인대 손상이 관찰되지 않았다. 따라서 상 ㆍ 하악 골밀도와 골구조의 차이를 고려하여 미니스크류의 골내 식립 길이를 적절히 조절함으로써 교정적 고정원으로 티타늄 미니스크류가 효과적으로 사용될 수 있다고 생각된다. Titanium miniscrews are being used increasingly as an anchorage for tooth movement, because they are easy to place and to remove, increase the number of sites available, give minimum strain to patients regarding surgical procedures, and offer uneventful healing after removal. The use of titanium miniscrews as an orthodontic anchorage has been reported in clinical case reports, but clinicians hove experienced screw loosening when using such screws. To our knowledge, there are no published reports evaluating the stability of miniscrews. Information about the length of miniscrews used in relation to the location is of some importance, as stability will vary depending on bone quality. The purpose of this study was to evaluate a variety of lengths of miniscrews (diameter: 2mm) which were inserted in maxilla or mandible and to demonstrate in a dog moedl which miniscrew provides fundamental stability in the jaws. 10 mm long miniscrews in the maxilla and 8mm long miniscrews in the mandible showed no clinical mobility and retained their position throughout an 8 weeks force (200g) application. The mucosal condition around the screws was healthy in cases in which miniscrews were inserted in the alveolar bone between the roots and the head of the screws emerged into the attached gingiva. When the force application was terminated, radiographic analysis revealed neither root resorption nor periodontal pathology around the miniscrews that remained stable during the entire treatment period. This study suggests that if titanium miniscrews with adequate length are properly used depending on the location, they provide sufficient stability for orthodontic anchorage.

To select potential inhibitors of platelet aggregation form large numbers of crude plant extracts, the modified thin smear method for the anti-platelet aggregating activity using platelet rich plasma was further modified by direct observation under a light microscope without staining the smear. The activities determined by the method were coincided with those by the electrical impedence method using whole blood, when ADP or collagen was employed as the aggregating agent. Among 130 varieties of edible and herbal plants which collected from markets or experimental farms of agricultural research institutes, those showed the anti-platelet aggregating activities were selected by testing the crude methanol extracts: Aster scaber, Aster tataricus, Ligularia stenocephala, Platycodon glaucum Allium victorials, Allium oderum, Morus bombycis, Portulaca oleracea, Acanthopanax sessiliflorus and Rosa davurica. However, some of them activated the platelet aggregation under the same assay conditions: Pimpinella brachycarpa, Hosta plantaginea. Capsella bursapastoris, Fagopym esculentum, Prunus mume, Rubus coreanus and Limaria japonica. In addition, those revealed the antioxidant activities were selected by measuring the abilities to scavenge superoxide anion radicals: Pteridum aquilinum, Aster scaber, Ligularia fischeri, Chrysanthemum zawadskii, Artemisia capipparis, Cirsium setidens, Commelina communis and Capsella bursapastoris among edible plants.

Mycobacterium genauense는 최근에 알려진 미코박테륨으로서, 식욕 부진, 체중 감소, 설사, 림프절 병증 등 파종성 Myocobacterium avium-intracellulare complex 감염과 유사한 임상상을 보이며, 위장관 침범을 잘 하는 것으로 알려져 있으나 아직 국내에서 증례는 보고된 바가 없다. 저자들은 진행된 HIV 감염 환자에서 십이지장의 미란성 병변으로 발현한 Mycobacterium genavense 감염 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 환자는 상복부 동통과 발열, 설사로 내원하였다. 십이지장의 미란성 병변에서 시행한 조직검사에서 항산균이 가득 차있는 거품세포가 관찰되었으며, 이 검체에서 16S rRNA 유전자의 중합연쇄반응 검사를 시행하여 Mycobacterium genavense를 확인하였다. Mycobacterium genavense, first identified in 1990, is known as a pathogen that mimics disseminated Myocobacterium avium-intracellulare complex (MAC) infection with particular propensity for the gastrointestinal tract. In Korea, no case with the organism has been reported. Herein we report a case of Mycobacterium genavense infection that manifested with erosive lesion of duodenum in a patient with acquired immune deficiency syndrome. The patient presented with epigastric pain and fever, diarrhea. Duodenal biopsy showed histiocytic infiltration with numerous acid-fast bacilli. Identification of the mycobacterial isolate by the polymerase chain reaction restriction analysis of 16S rRNA gene revealed Mycobacterium genavense.
