Sports scene is characterized by large amount of global motion due to pan and zoom of camera motion, and includes many small objects moving independently. Some short period of sports games is thrilling to televiewers, and important to producers. At the same time that kinds of scenes exhibit exceptionally dynamic motions and it is very difficult to analyze the motions with conventional algorithms. In this thesis, several algorithms are proposed for global motion analysis on these dynamic scenes. It is shown that proposed algorithms worked well for motion compensation and panorama synthesis. When cascading the inter frame motions, accumulated errors are unavoidable. In order to minimize these errors, interpolation method of motion vectors is introduced. Affined transform or perspective projection transform is regarded as a square matrix, which can be factorized into small amount of motion vectors. To solve factorization problem, we preposed the adaptation of Newton Raphson method into vector and matrix form, which is also computationally efficient. Combining multi frame motion estimation and the corresponding interpolation in hierarchical manner enhancement algorithm of motion parameters is proposed, which is suitable for motion compensation and panorama synthesis. The proposed algorithms are suitable for special effect rendering for broadcast system, video indexing, tracking in complex scenes, and other fields requiring global motion estimation.

Objectives : This work is aimed to reveal the relations between concepts of subhealth(mibyung) and Korean medicine patterns. Methods : We carried out a literature searching on Oasis, RISS, DBpia, Pubmed to summarize concepts of Mibyung. CNKI Searching also was performed with keyword related to mibyung(未病), subhealth(亞健康) and syndrome. Results : Korea, China and Japan have different concepts of mibyung. China's mibyung concept is relatively broader and wide which includes healthy, subhealth, development of disease and recurrence avoid. In contrast, Korea and Japan's mibyung concepts are focused on China's subhealth. Though Mibyung's patterns are varied widely depends on studies, China's studies of subhealth and TCM patterns showed that Deficiency patterns are diagnosed at high frequency in clinical study and literature study. Conclusions : This work could contribute to further study of subhealth(mibyung) and their relations to patterns, diagnostic methods and treatment efficacy.

1. Objectives: We report the relation between the questionnaire and the health state on the Sasang Constitution. 2. Methods: We carried out a clinical test, in which 2 Oriental medical doctors participated to diagnose health state in each Sasang Constitution with 239 subjects. The subjects were divided into 3 subgroups, which are allocated to healthy group, poor health group and disease group. 3. Results: We extracted 4 questions for Taeeumin, 5 questions for Soyangin and 3 questions for Soeumin from the whole 98 questions respectively. Soyangin and Taeeumin share a same question that shows significant difference by health status. For the statistical analysis, we used a Chi-square test. As a result, we found out that Taeeumin showed different distributions of answers in direct/indirect characteristic, perspiration, frequent urination, regular defecation. According to the health status Soyangin showed the different distribution of the answers in color of urination, frequent urination, mouth dryness, abnormal perspiration, discomfort of head. Soeumin showed the different distribution of the answers in cold and chilly feel of abdomen, digestion status and cause of digestion problems when body condition gets worse. 4. Conclusions: This is the first work which reports the relatedness between Questionnaire and Health State in each Sasang Constitutions by an objective clinical test. We found out that several questions have different distributions by health status in each Sasang Constitution. These extracted questions are categorized not only by Wansilmoobyung(완실무병), but also by other symptoms and body status.

2006년 봄철 광양만 해류의 구조와 변동

이재철,김정창,Lee, Jae-Chul,Kim, Jeong-Chang 한국해양학회 2007 바다 Vol.12 No.3

광양만의 순환을 이해하기 위하여 2006년 봄철에 수심이 가장 깊은 두 지점을 선정하여 ADCP가 장착된 모니터링 부표 2대를 이용하여 유속관측을 하였다. 두 지점에서 공통적으로 북향류가 지배적인데, 이는 서쪽의 남향류를 동반하는 반시계 방향의 순환 이 있음을 뒷받침 하고 있다. 남쪽에서는 14 m 수심에서 유향이 반전되는 2층 구조가 뚜렷하며 저층의 북향류는 바닥에 가까운 36 m 수심까지 증가한다. 북쪽 지점에서는 북향류가 더욱 강해져서 북쪽의 단면적 감소에 따른 해류의 가속 효과가 있으며 상층부에서도 북향류가 우세하다. EOF 분석을 통한 연직구조에 있어서 첫 번째 모드는 북쪽 부표에서 전체 분산의 74%인데 비하여 남쪽 부표에서는 67%로 감소하고 상대적으로 2층 구조의 비중이 크다. 반시계 방향의 순환과 관련된 북향류의 전형적인 유속은 약 10 cm/s이다. 여기에 중첩되는 변동성으로서 국지적인 바람의 영향은 거의 받지 않는 반면에 동-서 방향의 바람에 의한 외해의 에크만 수송과 관련된 비국지적 영향은 주로 풍속이 강할 경우에 나타난다. Two monitoring buoys equipped with ADCP were deployed at the deepest positions along the trough of the central Gwangyang Bay in spring 2006 in order to study the circulation in the bay. Northward velocity is commonly dominant at both stations located in the eastern part of the channel, which supports the cyclonic circulation accompanied by the southward flow in the western part. The southern station has a distinct two-layer structure with current reversal at 14 m depth and increasing northward velocity in the lower layer to 36 m depth close to the bottom. At the northern station the northward flow becomes accelerated due to the decrease in the cross-sectional area and this northward current is dominant even in the upper layer. In the modal structure from the EOF analysis, the first mode has 74% of total variance at the northern station whereas it is 67% but the baroclinic portion increases at the southern station. The typical northward velocity is about 10 cm/s which is associated with the cyclonic circulation. Subtidal variability due to the local wind effect is negligible, but the nonlocal response associated with offshore Ekman flux by the zonal wind is found during strong wind events.

夏季 韓國 南東海域에서 湧昇과 關聯된 바람, 海水面 및 表層水溫의 變化 TEVARIATIONS OF SEA LEVEL AND SEA SURFACE TEPERATURE ASSOCIATED WITH WIND -INDUCED UPWELLING IN THE SOUTH

이재철,Lee, Jae Chul 한국해양학회 1983 韓國海洋學會誌 Vol.18 No.2

Extensive wind, sea level and sea surface temperature (SST) data collected along the east coast of Korea in 1973-1979 were used to ascribe the variations of sea level and SST associated with wind forcing during summer. Alongshore components of wind were dominant but the offshore components were little significance in the southeast coast in summer. The variations in SST and sea level adjusted barometricallyagreed with the upwelling-downwelling processes and showed a rapid response to wind.Appearance of cold water to the surface in the upwelling region concurred well with te periods of positive y-component wind when the tangential line at Ulgi was takem as the y-axis. In general, SST at Ulgi and Gampo as well as the adjusted sea level at Pohang, Ulsan and Busan decreased significantly when strong winds favorable for upwelling persisted for more then three days whereas they increased during the relaxation or unfavorable periods. The period of an upwelling event, on the average, was about 10 days and the mean speed of alongshore sind was 4.0m/sec.

1. Objectives: This study was performed to research the relationship between Sasang Constitution and characteristics of tongue diagnosis based on Donguisusebowon's Experience prescriptions(經驗方). 2. Methods: We searched tongue diagnosis factors in Donguisusebowon and classified this. Based on Donguisusebowon's Experience prescriptions(經驗方), we find tongue diagnosis factors in 6 contemporary Oriental medicine prescription books. 3. Results: Most So-eumin has white thin tongue coating and clear redish tongue color. Yellow tongue coatings are found in symptoms for Yinjinho-tang(Yinchenhao-tang), Soseungki-tang(Xiaochengqi-tang), Daeseungki-tang(Dachengqi-tang). Shortened Tongue is found in So-eumin's experience prescription and So-yangin's treat histroy. It didn't shown that So-eumin's Semen Crotonis included 6 prescritions' factors of tongue diagnosis. So-yangin's white tongue coating is found in Hyungbangpaedok-san(Jingfangbaidu-san), Sipjo-tang(Shizao-tang), Sosiho-tang(Xiaocihu-tang), Shinki-hwan(Shenqi-wan). Most of other So-yangin's tongue coatings are Yellowish and tongue color is deep red. Tae-eumin have thin white tongue coating at the Mahuang-tang(Mahuang-tang). Red tongue color and drying tongue are found at Jowiseungki-tang(Tiaoweichengqi-tang)Daesiho-tang(Dacihu-tang)Saengmaek-san(Shengmai-san) 4. Conclusions: Following So-eumin's Experience prescriptions, So-eumin's tongue color is clear red and tongue coatings are thin white and greasy. Following So-yangin's Experience prescriptions, So-yangin's tongue color is deep red and tongue coatings are yellowish and scarce except Exterior cold disease. And So-yangin has specific symptom of irritability, oral sores. Tae-eumin's tongue has two sides of white thin tongue coatings and Red and drying tongue.

Structure of Upwelling off the Southease Coast of Korea

이재철,나정열,Lee, Jae-Chul,Na, Jung-Yul The Korean Society of Oceanography 1985 韓國海洋學會誌 Vol.20 No.3

Hydrographic data and daily time series of longshore wind, sea level and sea surface temperature were used in order to explain why the upwelling effect in SST is especially prominent near Ulgi-Gampo although the sea level records along the whole southeast coast show a nearly uniform upwelling-downwelling response to wind. Regional difference in intensity of the wind-induced upwelling represented by the SST decrease is attributed to the combined influence of two factors; one is the baroclinic tilting of isotherms due to the East Korea Warm Current (EKWC) near the Ulgi-Gampo coast, the other is the topographic effects around the southeast coast. Baroclinic tilting effect of EKWC which is generally strongest near the coast of Ulgi to Gampo results in both of the shoaling of cold water and the westward trapping of the coldest bottom water over the shallower shelf rather than the deepest troough region off that coast regardless of the season. Therefore, becacse of the cold water ready for upwelling at the subsurface layer, SST responds very rapidly to the upwelling-favorable winds of summer only off the Ulgi-Gampo coast. Spreading isobaths from Pusan to Gempo can reinforce the upwelling of the cold bottom water and its westward trapping.
