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.

목 적 : 후방 십자 인대 손상의 치료로서 관절경적 후방 십자 인대 재건술을 시행하여 임상 결과를 분석하고자 하였으며, 특히 추시상 후방 불안정의 재발 여부와 자가 골-슬개건-골을 이용하여 재건한 경우 및 동종 이식물을 이용한 결과를 비교 분석하였다. 대상 및 방법 : 1994년 1월부터 1999년 5월까지 본원에서 수술 치료한 총 34례의 후방 십자 인대 손상의 환자 중에서 전외측 다발만을 관절경적으로 재건술을 시행하고 12개월 이상 최종 추시가 가능했던 25례 중 자가 반건양건을 이용한 1례를 제외한 24례를 대상으로 하였으며, 24례 중 자가 골-슬개건-골을 이용하여 재건한 경우를 제 I군(11례), 동종 아킬레스 건을 이용하여 재건한 경우를 제 II군(7례), 동종 골-슬개건-골을 이용하여 재건한 경우를 제 III군(6례)으로 하였다. 평가 방법은 24례 모두를 International Knee Documentation Committee(IKDC) knee ligament standard evaluation form, Lysholm knee scoring scale을 이용하여 세 집단을 비교하였으며 전 후방 안정도의 측정을 위해서 $KT-2000^{TM}$ knee ligament arthrometer MED metric, USA(KT-2000)를 사용하였다. Kruskal-Wallis test와 Mann-Whitney U(Wilcoxon Rank Sum) 검정법을 이용하여 세 집단을 비교 통계 분석하였다. 결과 : IKDC 최종 평가상 B(거의 정상)이상은 전체 24례 중 11례$(46\%)$로 만족스러운 결과는 아니었고, KT-2000으로 측정시 양측 비교하여 6mm 이상 차이가 나는 경우는 제 I군 4례$(36\%)$, 제 II군 2례$(29\%)$, 제 III군 2례$(33\%)$에서 후방 불안정성을 보였다. Lysholm knee scoring scale을 이용한 평가 결과는 제 I군이 평균 78점 (fair), 제 II군이 75점(fair), 제 III군이 76점(fair)이었다. 재료에 따른 각 군간의 객관적, 주관적 결과의 차이는 보이지 않았다. 결론 : 후방 십자 인대 손상시 불안정의 정도가 심하지 않은 단독 손상을 제외하고는 관절경적 재건술이 보편화 되는 추세이나, 보다 정확한 수술 술기와 동반 손상에 대한 치밀한 치료 계획이 요구되며, 새로운 시도와 그에 따른 많은 연구가 필요할 것으로 생각된다.

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).
