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.

절연물층을 확산시킨 (Ba0.5, Sr0.5)TiO₃박막의 전류-전압 특성

진병태,김진철,김명호 國立 昌原大學校 産業技術硏究所 1998 産技硏論文集 Vol.12 No.-

The mixture of PbO-Bi₂O₃-B₂O₃(PBB) phase was formed in the Ba0.5Sr0.5TiO₃(BST) film and the effects of PBB phase on the dielectric properties of the BST film were investigated. The amorphous PBB layer was deposited on the BST film using rf magnetron sputtering and diffused into the film by heat treatment. The PBB phase in BST film was identified by energy dispersive spectrometer (EDS). Dielectric properties of BST film were significantly improved after the diffusion of PBB. The leakage current density of BST film decreased from 3.24×10(-5) A/㎠ to 9.45×10(-8) A/㎠ at 1.5 V and the dielectric constant increased from 238 to 533. These results show that the formation of insulating metal oxide in the ferroelectric film can improve the dielectric properties of the film.

Objectives : The purpose of this study was to investigate the prevalence of erectile dysfunction (ED) in a rural area of Korea and to examine the relationship between the prevalence and correlates of subjects. Method : This study was done as a part of the chronic disease survey of rural area by the Asan Foundation. Among 30 years or older population from Jung Eup, a rural area of Korea, 711 male subjects were sampled using a cluster probability sampling method. Trained interviewers visited and interviewed subjects aged 30 years or older with a structured interview. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. Response rate was 54.3% (N=386). Results : The age weighted prevalence of ED was 27.2% (minimal 14.1%, moderate 7.6%, severe 5.5%). Prevalence and severity increased with age. Liver disease and underweight were significantly (p<0.05) associated with ED. Smoking seemed to be correlated with ED, but did not reach statistically significant level. Conclusion : ED was highly prevalent in the rural community of Korea. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology.

동종 골수이식 후 만성 이식편대숙주질환과 동반되어 신증후군으로 발현된 IgA 신병증 1예

정철권,김현수,박준성,정성현,조도연,최진혁,남동기,임호영,김명성,신규태,임현이,김효철 대한조혈모세포이식학회 1999 대한조혈모세포이식학회지 Vol.4 No.2

동종 골수이식 후 발생하는 신기능부전은 원인이 다양하여 감별에 어려움이 있다. 만성 GVHD는 흉선의 기능저하에 따른 면역관용의 실패로 발생되는 자가면역현상에 의해 발생되는 것으로 알려져 있으며 드물게 신장을 침범하여 신증후군을 일으키기도 한다. CaA의 용량을 줄이거나 투약중지 후 발생한 만성 GVHD에 동반된 신증후군의 경우 조기에 신조직검사를 시행하여 감별진단하고 CsA의 용량을 증량하거나 재투약하여 좋은 치료 결과를 보일 것으로 기대된다. 저자들은 문헌고찰을 통해 동종 골수이식 후 발생된 신증후군이 유사한 임상양상을 보이며 발생기전에 만성 GVHD와 자가면역현상이 연관되어 있음을 확인하였으며 동종 골수이식 후 신증후군의 임상양상을 보이는 환자에서 병리조직학적으로 lgA 신병증을 진단하고 이러한 lgA 신병증이 발생기전에 만성 GVHD와 자가 면역현상이 연관되어 있을 가능성을 최초로 확인하였으며 CsA를 이용하여 성공적으로 치료한 경험을 하였기에 보고하는 바이다. Renal insufficiency is occasionally encountered in allogeneic bone marrow transplantation and its cause is difficult to ascertain. Chronic graft-versus-host disease (GVHD) related to thymic dysfunction is immune-mediated and involves autoreactivity of T-lymphocytes derived from donor marrow to recipient's major histocompatibility complex(MHC) minor antigens. The clinical mainifestations of chronic GVHD are similar to those of autoimmune disease but kidney involvement is rare. Few cases of nephrotic syndrome with membranous nephropathy or minimal change nephrotic syndrome have been reported to be associated with chronic GVHD in allogeneic bone marrow transplant recipient especially after cyclosporine A(CsA) withdrawal, and these cases have responded well to CsA. Therefore, it is prudent to differentiate the cause of post-transplant renal insufficiency using renal biopsy and to start CsA in a case of nephrotic syndrome associated with chronic GVHD as early as possible. We report a case who had a massive proteinuria during the post-allogeneic marrow transplantation period. The cause of nephrotic syndrome was diagnosed as IgA nephropathy by renal biopsy. The patient was successfully treated with reintroduction of CsA.

미래의 ULSI 소자의 게이트 산화막으로 이용하기 위하여 N₂O 가스 분위기에서 기존의 전기로를 이용한 실리콘의 열산화에 의해 N₂O 산화막을 형성하였고, MOS 소자를 제작하여 전기적 특성을 고찰하였다. 900℃에서 90분간 산화한 N₂O 산화막의 경우, 플랫밴드 전압(??), 고정전하밀도(??)와 플랫밴드 전압의 변화량(??)은 각각 0.81 [V], ?? [??]와 80∼95[mV]를 나타내었다. N₂O 산화막의 전기전도기구는 저전계 영역에서는 Fowler-Nordheim 터널링, 고전계영역에서는 Poole-Frenkel 방출이 지배적으로 나타났고, 절연파괴전계는 16 [MV/㎝]로 높게 나타났다. 따라서 N₂O 산화로 형성된 게이트 산화막이 ULSI 소자의 게이트 유전체로 응용이 가능하리라 생각된다. In order to applicate gate insulators in future ULSI devices, electrical properties was investigated in MOS device with N₂O oxide grown by thermal oxidation using conventional furnace in N₂O ambient. For the sample oxidized at 900℃ for 90 min, Flatband voltage(??), fixed charge density(??) and shifts of flatband voltage(??) after BTS was obtained 0.81 [V], ?? [??] and 80∼95[mV], respectively. The dominant conduction mechanism of N₂O oxide appeared to be Fowler-Nordheim tunneling in the low electrical field region(4-6 [MV/㎝]) and to be Poole-Frenkel emission in the high electrical field region( 9 [MV/㎝] or above). Dielectrics breakdown fields of N₂O oxide appeared about 16 [MV/㎝]. These results suggest that the N₂O oxides is a promising candidate for ultrathin gate dielectric for MOS ULSI applications.

두경부 자세 및 혀, 설골의 위치와 두개안면골격간의 연관성을 알아보기 위해, 원광대학교 치과대학 재학생 중 선천적 두경부 이상이나 결손치가 없고 과거 교정 치료나 보철치료의 경험이 없는 남자 50명과 여자 40명을 대상으로 natural head position(NHP)상태에서 두부방사선 사진을 채득하여 전통적인 두개내 참고선과 두개의 진성 참고선을 이용하여 계속한 결과 다음과 같은 결론을 얻었다. 1. 두경부 자세변수들에서는 남녀간 차이가 없었으나, 설골의 위치는 남자가 여자에 비해 더 전하방에 위치하였으며, 더 큰 전하방 경사도를 보였다. 2. 경추의 경사도가 클수록 NHP에서 안면돌출도는 작게 나타났으며, 경추의 전방만곡이 증가할수록 수직적인 안모형태를 보였다. 3. 두경부각이 작을수록 두개저에 대하여 설골이 전방에 위치하였으며, 두경부각과 설골의 수직적인 위치는 연관성을 보이지 않았다. 4. 하악골이 전돌될수록 설골은 전방에 위치하였으며, 두개안면형태와 설골의 수직적인 위치는 미약한 연관성을 나타냈다. The purpose of this study was to examine the associations of head posture, the position of the tongue or the hyoid bone to craniofacial structure. Cephalograms taken in Natural head position(NHP) of 90 dental students (50 in male, 40 in female, 20 to 30 years in age) were traced and measured using the extracranial true horizontal and vertical lines. The obtained results were as follows; 1. There was no sex difference in head posture, but the hyoid bone was placed anteroinferiorly in male more than in female and anteroinferior inclination of the hyoid bone showed greatly in male. 2. The more inclined was the cervical column, the less prognathic was the face in natural head posture, and the larger cervical curvature, the more vertical pattern of the face. 3. The less small showed craniocervical angulation, the more anteriorly placed was the hyoid bone to the cranial base, and there was no significantly association between craniocervical angulation and the vertical position of the hyoid bone. 4. The more prognathic was the mandible, the more anteriorly placed was the hyoid bone, and there was slightly association between the craniofacial morphology and the vertical position of the hyoid bone.
