In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

송주섭,김경아,고광준 대한구강악안면방사선학회 2006 Imaging Science in Dentistry Vol.36 No.2

Peripheral ameloblastoma is an extremely rare odontogenic soft tissue tumor with histologic characteristics similar to those of the intraosseous ameloblastoma. It appears in the gingiva and oral mucosa. And it usually does not show any bone involvement on radiographs, except for saucer shaped erosion of underlying alveolar bone. Recurrence is considered uncommon. We report a case of peripheral ameloblastoma with bone involvement. Histologically it presented with follicles and nest of tumor cells with palisading pattern. And radiographs showed the typical saucer shaped alveolar bone erosion at the distal area of right mandibular third molar. At 6-month follow-up after operation, no local recurrence was noted.

The magnets were widely used to increase the retention of overdentures. The purpose of this study was to compare the break load between overdentures and edentulous models. For this study, Model former(U-402) was used for model fabrication and four different magnets were used for evaluation of break load. The artificial saliva was used between overdenture and model. Breakaway loads were tested with an Instron 1122 at a speed of 2mm/min. The results were as follows. 1. The retentivee forces complete dentures with artificial saliva were than the retentive forces of complete detures without artificial saliva. 2. Magnetic overdenture with artificial saliva showed best retentive force, magnetic overdenture without artificial saliva showed the next retentive force, and the complete denture without artificial saliva showed the worst retention. 3. As the magnetic sizes increased, the retentive forces of magnetics were increased. 4. The retentive force of nipple shape magnet is greater than the retentive force of flate shape magnet in the same size.

홍진후,송주명,김현경,박미영,박기주 조선대학교 생산기술연구소 1999 生産技術硏究 Vol.21 No.2

Polyesterimide for enamel Wire coating was synthesized and its curing reaction was monitored by real-time FT-IR. Infrared 1019cm^(-1) band was used to monitor the curing process. Results of in-situ analysis showed that evaporation of ethylene glycol and transesterification started from 100℃. When curing temperature was higher than 200℃, ester reaction was favored over the ether reaction. It was concluded that curing temperature is the key factor to control the thermal stability of the enamel wire coating.

저자들은 만성 기침이 있었으나 정확한 원인을 찾지 못한 채 보존적 치료만 받던 베체트병이 있는 37세 여자환자를 경험하였고 흉부 방사선사진과 흉부 전산화 단층 촬영으로 폐동맥류로 진단하고 고용량의 스테로이드로 치료하였고 이 과정에서 대량 객혈이 있었으나 보존적 치료로 호전된 베체트병 1 예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Pulmonary Artery Aneurysm Manifesting as Chronic cough in Behcet's disease Behcet's disease is a relapsing chronic inflammation disorder of unknown etiology. Although Behcet's disease has originally been described as a triad of recurrent oral aphthous ulceration, genital ulceration and uveitis, it is now recognized as a multisystem disease with vasculitis as the main pathological finding. Clinical manifestations additional to this triad include involvement of the skin, joints, large vessels, lung, gastrointestinal and genitourinary tracts, brain. We report a case of pulmonary artery aneurysm manifesting as chronic cough in Behcet's disease. She was a 47 year-old woman with Bechet's disease treated with prednisolone and colchicine. She had suffered from chronic cough for several years, but been treated only with antitussive agents. Chest CT revealed multifocal patchy consolidation in lung parenchym and aneurysmal dialatation of pulmonary artery. We diagnosed pulmonary aneurysm with CT finding as the cause of chronic cough.

Purpose : To assess bone changes of mandibular condyle using cone beam computed tomography (CBCT) in temporomandibular disorder (TMD) Patients. Materials and Methods : 314 temporomandibular joints (TMJs) images of 163 TMD patients were examined at the Department of Oral and Maxillofacial Radiology, Chonbuk National University. The images were obtained by PSR9000N (Asahi Roentgen Co., Japan) and reconstructed by using Asahivision software (Asahi Roentgen Co.,Japan). The CBCT images were examined three times with four weeks interval by three radiologists. Bone changes of mandibular condyle such as flattening, sclerosis, erosion and osteophyte formation were observed in sagittal, axial, coronal and 3 dimensional images of the mandibular condyle. The statistical analysis was performed using SPSS 12.0. Intra-and interobserver agreement were performed by 3 radiologists without the knowledge of clinical information. Results : Osteophyte (2.9%) was found more frequently on anterior surface of the mandibular condyle. Erosion (31.8%) was found more frequently on anterior and medial surfaces of the mandibular condyle. The intraobserver agreement was good to excellent(k=0.78-0.84), but interobserver agreement was fair(k=0.45). Conclusion : CBCT can provide high qualified images of bone changes of the TMJ with axial, coronal and 3 dimensional images.

The purpose of this study is to evaluate the acid resistance of cement mortar admixed with waste phosphogypsum by steam curing admixture. Waste Phosphogypsum is a by-product from the phosphoric acid process for manufacturing fertilizers. It consists mainly of CaSO₄·2H₂O and contains some impurities such as P₂O_5, F^(-) and organic substances. The waste phosphogypsums is made use of 4 forms(Dihydrate, β-Hemihydrate, Ⅲ-Anhydrite and Ⅱ-Anhydrite) which were changed to in low temperature of calcination. The mass change and reduction ratio of compressive strength of cement mortar are investigated to evaluate the acid resistance. The specimens of cement mortar were immersed in HCI(5%) and H₂SO₄(5%, 10%) during 14, 28 and 56days. As a result, mass change and reduction ratio of compressive strength of cement mortar admixed with waste phosphogypsum are lower than cement mortar contained OPC alone. Also, Ⅲ-Anhydrite is comparable to Ⅱ-Anhydrite in acid resistance. Therefore, Ⅲ-Anhydrite phosphogypsum calcined at lower temperature could be used as steam curing admixture for concrete 2th production.
