  • Benign fibrous mesothelioma of the pleura is a relatively rare neoplasm originated from pleural mesothelial cell, often asymptomatic or presenting with a specifical sign. One of the main problems, concerns the preoperative differential diagnosis, mainly because it is difficult to differentiate between benign and malignant type. A 62-year old woman presented with recurrent chest pain. The chest radiography in a patient was suspected localized pleural mesothelioma. The chest computed tomography scan showed that mass like lesion of well marginated ovoid shape with homogenous attenuation on anterior-basal segment of right lower lobe. After resection of a pleural mass by thoracoscopic extirpation from right hemithorax, Localized benign fibrous mesothelioma of the pleura was confirmed by pathology and immunohisto-chemical staining. We report here one case of pleural benign fibrous mesothelioma with some considerations on its diagnosis and treatment.

  • Problem of testing linearity among general class of first order nonlinear time series models is discussed. The null hypotheses of linearity is identified via conditional expectations. A consistent test is then suggested and relevant limiting results are derived. It is worth indicating that any specific alternatives are not specified.

  • Purpose : The purpose of this study is to evaluate the clinical results after arthroscopic PCL reconstruction and to compare the clinical results after arthroscopic PCL reconstruction using BPTB(bone patellar tendon bone) autograft(Group I : 11 cases), Achilles tendon allograft(Group II : 7 cases) and BPTB allograft(Group 111.6 cases). Materials and Methods : We reviewed the result of 24 patients who had been managed with arthroscopic reconstruction using different graft materials such as BPTB autograft, Achilles tendon allograft and BPTB allograft. Twenty-four patients(average age, 37 years) with PCL rupture were retrospectively evaluated more than one year(average, 31 months) after having arthroscopic posterior cruciate ligament reconstruction. The clinical results were evaluated by IKDC ligament standard evaluation form, using $KT-2000^{TM}$ knee ligament arthrometer and also evaluated Lysholm knee scoring scale. Results : The final evaluation was nearly normal in 11 patients($45\%$ in Group I, $43\%$ in Group II, $50\%$ in Group III). The corrected posterior sagging was abnormal(side to side difference more than 6mm) in 8 patients($36\%$ in Group I, $29\%$ in Group II, $33\%$ in Group III). We could not find significant difference among three groups by IKDC scale. Conclusion : Comparing with other reports, our overall results were not satisfactory. And also, we could not find any remarkable difference among the three groups. Further research is necessary to evaluate new surgical approaches as well as improved techniques for capsular and collateral ligament injuries.

  • The concomitant presence of posterior mitral annular calcification and infectious mitral valve lesions poses a technical challenge with considerable perioperative risk when using previously proposed techniques for mitral valve surgery. Herein, we report a case of the use of a modified surgical technique to successfully treat a patient with mitral infective endocarditis complicated by a subendocardial abscess and extensive posterior mitral annular calcification.

  • Estimation of the general along-track acceleration was performed in the KOMPSAT-1 orbit determination process. Several sets of the atmospheric drag and solar radiation pressure coefficients were also derived with the different spacecraft area. State vectors in the orbit determination with the different spacecraft area were compared in the time frame. The orbit prediction using the estimated coefficients was performed and compared with the orbit determination results. The orbit prediction with the different general acceleration values was also carried out for the comparison.

  • In the present work, we investigate a viscoelastic equation involving a logarithmic nonlinear source term. After proving the existence of solutions, we establish a general decay estimate of the solution using energy estimates and theory of convex functions. This result extends and complements some previous results of [9, 21].

  • The purpose of this study is to investigate the symbolic meaning of pattern designs attached on the main building of Chungcheongnam-do Provincial Government (CPG). While most of researches mainly focused on the value and evaulation of the CPG building in terms of architectural history, relatively little insight has been gained on the symbolic meaning and mature of the pattern designs. What king of connections are related between the emblem of Governor-General of Chosun(Korea) and those of CPG? What symbolic meanings are engraved on the pattern designs? The researcher then took up the task of elucidating symbolic meanings of patterns and their relation to the building. The existing pattern of the outer wall of the CPG building consists of the symbol of sun(太陽輪), mums(菊花輪), and angle of stairs(雁大角). According to the Japanese Studies of emblems, these visual elements symbolize 'the sun of Japan'((日の丸) or 'the emperor', 'the royal family', and 'rays of the sun'. Based on these preliminary findings, the researcher considered the following in-depth connections: (1) relations with the emblem of Governor-General of Chosun, (2) relations with the emblems of local autonomous entity, Kyoungsung in Chosun. (3) relations with the emblem designs of the local provinces in Japan etc. In conclusion, patterns of the main building were not just an architectural decoration, but they had significant meanings utilizing design elements and methods adopted by local autonomous entities in Japan, The patterns found at the ceilling and floor of hall in the CPG building were associated with the emblem of Governor-General of Chosun. Therefore, all the patterns of the CPG building are powerful symbols that have meanings for the colonial rule by using the shape and method of city identities that Japanese local provinces had enacted. That is, it came out into the open that they were designed for special meanings that Korean and Japanese are united as a single body(內鮮一體) for a subject of the Emperor of Japan(皇國臣民).
