This paper describes the possibility of evaluating and classifying arthritic pathology using the acoustical analysis of knee joint sound. Six normal subjects and 11 patients with knee problems were enrolled. Patients were divided into the 1st patient group which required an orthopeadic surgery and the 2nd patient group of osteoarthritis. During sitting and standing periods, subjects' active knee flexion and extension were monitored. Fundamental frequency, mean amplitude of pitch, jitter and shimmer were analyzed according to the position. The results demonstrate that the values of fundamental frequency, jitter and shimmer of the 2nd patient group were larger than others and changed unstably. The values of the standing position were larger than the sitting position.

Quetiapine is an atypical antipsychotic drug with a benign side effect profile. However, recent studies have reported that thyroid dysfunction is associated with quetiapine treatment. The authors report a patient with DSM-IV bipolar I disorder who developed subclinical hypothyroidism during quetiapine treatment. The patient showed no significant clinical symptoms, but only abnormal thyroid function test findings including antithyroglobulin antibody. The abnormal thyroid function test findings were normalized after discontinuation of quetiapine. The subclinical hypothyroidism developed during quetiapine treatment may be associated with autoimmune process.

In this study, the spray models incorporated into the GTT code were tested for sprays injected in quiescent swirling gases and for the sprays impinging on a flat wall, and the validity of the models has been confirmed by comparing the calculated results with the experimental data. Using this code, the gas flow, spray behavior and fuel vapor distributions in the combustion chamber of a D.I engine have been numerically analyzed with respect to the constant injection pressure and the injection pressure varying with injection time.

Video composition is to integrate multiple image materials into one scene. It considerably enhances the degree of freedom in producing various scenes. However, we need to adjust the viewing point sand the image planes of image planes of image materials for high quality video composition. In this paper, were propose an intelligent video composition technique concentrating on the composition of CG and real scene. We first model the camera system. The projection is assumed to be perspective and the camera motion is assumed to be 3D rotational and 3D translational. Then, we automatically extract camera parameters comprising the camera model from real scene by a dedicated algorithm. After that, CG scene is generated according to the camera parameters of the real scene. Finally the two are composed into one scene. Experimental results justify the validity of the proposed method.

The spray models incorporated into the GTT code were tested for free spray, spray in swirling flows and the sprays impinging on a flat wall. And the validity of the models has been confirmed by comparing the calculated results with the experimental data. Using this code, the spray behavior in the diesel combustion chamber have been numerically analyzed for variation of nozzle diameter. Also, the effects of nozzle diameter in diesel combustion was investigated experimentally by measuring the performance in a D.I engine. This study provides the information for the spray characteristics and emissions with variation of nozzle diameter. As a result, it has shown that decreasing nozzle diameter resulted in improving smoke and specific fuel consumption in a middle speed range.

The effect of water spray for the fire sprinkler depends on droples distribution over maximum possible floor area. The present study are carried out for the characteristics of water spray and droplets experimentally and numerically km two fire sprinkler heads which are CHM head and CHl heal CHl head is self-production and CHl head is widely used up to date. As the result of using CHM head, water spray and droplets are distributed over large area because CHM head has smooth surface and non-flamed shape. When the pressure of fire sprinkler head is low, SMD(sauter mean diameter) is large and when the pressure of fire sprinkler head is high, SMD is small.

This paper analyzes the thesis classification of the "Korean Philosophy Journal" and the subject and characteristics of two representative scholars of the Research Society in commemoration of the 30th anniversary of the establishment of the 'Korean Philosophy History Research Society'. The "Korean Philosophy Journal" was published from the 1st edition in 1991 to the 55th edition until November, 2017, and introduced a total of 582 papers. In the meantime, the 'Korean Philosophy History Research Society' became a registered place after being nominated by the Korea Research Foundation. Among the 582 chapters, 297 papers deal directly with Korean philosophy, and 174 papers on Chinese philosophy. Among the Korean philosophical theses, the most popular one was the 198th issue, and the Chinese philosophical thesis was the most popular with the subject of theology. Among the Korean philosophers, Chung Yak - Yong and Chinese philosophers Chu Shi were the most studied. Among the writers who participated in the "Korean Philosophy Journal", 203 were all of them. Among them, Lee Sang Ik published the most articles with 28, and Choi Young Sung was the second with 23. Based on Lee Sang Ik 's thesis 28, Lee Sang Ik is a well - known neo - Confucianism scholar. His research is based on the theory of neo - Confucianism and the theory of secularism. On the one hand, he establishes his own moral theories and criticizes other moral theories. On the other hand he establishes his own governing theory and criticizes other governing theories. And theoretical proposals on various problems in modern society Based on Choi Young Sung 's thesis, 23, Choi Young Sung is the best researcher in the field of studying in Korea. His research focuses on correcting mistaken perceptions and descriptions in the history of study abroad in Korea, and developing the undeveloped parts. In addition, I am looking for a new perspective on the history of studying in Korea. In addition, he has been studying the philosophical thought of Choi Chih Won in order to establish a philosophical foundation for approaching the history of thought rather than just the study of the history of thought. The "Korean Philosophy Journal" has been advanced in quantity and quality, and has developed quantitatively and qualitatively. Revitalization of the SungKyunKwan university Korean Philosophy Department is indispensable for the continuous development of "Korean Philosophy Journal" and 'Korean Philosophy History Study Society' and to create excellent scholars.
