A framework for semantic annotation oi human motion sequences is proposed in this paper. Motion capture technology is widely used for manuiacturing animation since it produces high qualify character motion similar to the actual motion of the human body. However, motion capture has a significant weakness due to the lack of an industry wide standard for archiving and retrieving motion capture data. It is difficult for animators to retrieve the desired motion sequences from motion capture files as there is no semantic annotation on already captured motion data. Our goal is to improve the reusability of motion capture data. To archive our goal first, we propose a standard format for integrating different motion capture file formals. Our standard format is called MCML (Motion Capture Markup Language). It is a markup language based on XML (extensible Markup Language). The purpose of MCML is not only to facilitate the conversion or integration of different formats, but also to allow for greater reusability of motion capture data, through the construction of a motion database storing the MCML documents Second, we define motion ontologies that are used to annotate and semantically organize human motion sequences. This ontology-based approach provides the means for discovering and exploiting the information and knowledge surrounding motion capture data.

This paper is aims to build the advancement structural model of GICOMS through identification of required system and improvement for implementation of e-Navigation. We derived nine improvement subject for model of advanced GICOMS through the analysis of problems for GICOMS and brainstorming with expert in the maritime safety. And we analyzed the structure of nine improvement subject using by FSM(Fuzzy Structural Modeling) method, and proposed a structural model that to grasp the correlation between elements. As a result, we found out that "advancement of GICOMS" is the final goal, and "improvement a system of information production", "improvement a scheme of information providing", "linkage between GICOMS and VTS" and "building global networks for safety cooperation" are located lowest level. Especially, "advancement of GICOMS" is influenced by "advancement function of VMS" and "Activation of usage" on middle level. We suggested that utilizing state-of-the-art IT facilities, equipment and expertise to improve and enhance the user-centered transition such as maritime workers for advancement of GICOMS based on proposed structure model.

Objectives : KangHaiChengZhiLun (亢害承制論; If Excess Brings Harm, Lifing Qi (承氣) Restrains) was originally a theory that explained how the realms of nature remain in harmony and equilibrium. It later became an important theory for clinical trials of Traditional Chinese Medicine, explaining the physiological and pathological mechanism. Methods : The researcher considered all the annotations and the original text of SuWen(素問), LiuWeiZhiDaLun(六微旨大論) and theories of medical practitioners who applied KangHaiChengZhiLun(亢害承制論) to their clinical trials. Results & Conclusions : Wangbing (王氷) went with a theory that phenomena of Lifting Qi (承氣) take place in the realms of nature when Qi (氣) flourishes. In XinJiaoZheng(新校正), he wrote about two theories: one was that Six Kinds of Natural Factors (六氣) first work as the main Qi (本氣) but later bring about Lifting Qi. (終見下承之氣說); the other was that excessive Stagnation Qi (鬱氣) can be exploded and invite another accompanying Qi, Lifting Qi. (甚者兼其下承之氣說) Liuwansu (劉完素) had a theory that if Six Kinds of Natural Factors go disproportionately excessive, it becomes accompanied by imaginary Qi (假象) that conquers self. (反兼勝己之化說) $Wangl{\ddot{u}}$(王履) maintained that Lifting Qi usually works as a means to prevent Six Kinds of Natural Factors (六氣) from becoming rampant; but when Six Kinds of Natural Factors become overly excessive, Lifting Qi restrains them in order to maintain equilibrium. (防之與克勝說) Yutuan explained that since Excessive Qi (亢氣) does damage to the mother of Lifting Qi, Lifting Qi restrains Excessive Qi to protect Original Qi (元氣), its mother. (護救承者之元氣說) Gongtingxian was in favor of two theories: one argued that causes and symptoms of a disease differ from each other. (體用不同說); the other said that diseases are naturally cured if the patient finds out the time when Lifting Qi gains strength. (得承之時自愈說) Mashi (馬蒔) had a theory that Lifting Qi is generated when Six Kinds of Natural Factors are prosperous and reveals itself when its season comes. (極則生承氣 至本位著說) Zhangjiebin (張介賓) asserted that when Six Kinds of Natural Factors are thriving, Lifting Qi, as a restraining force, is generated to disperse the thriving natural factors and leads to a new one. (前之退而後之進說) Zhangqi (張琦)'s argument was that if Lifting Qi restrains the main Qi, a son of the main Qi is generated and every four season goes in harmony. (承氣制則生化說) Hemengyao (何夢瑤) had an argument that a son of the restrained Qi succeeds to its father and later achieves equilibrium by restraining Excessive Qi. (被克承父 制之平衡說).

The ship sailing among waves are suffered the various wave loads that comes from its motion throughout its life. Because there are dynamic, the analysis of ship structure must be considered as the dynamic problem precisely. In the rationally-based design, the dynamic structural analysis is carried out using dynamic wave loads provided from the results of the ship mouton calculation as the rigid body. This method is based on the linear theory assumed low wave height and small amplitude of motion. But at the rough sea condition, high wave height, relatively ship's depth, is induced the large ship motion, so the ship section configulation below water line is rapidly changed at each time. This results in non-linear problem. Considering above situation in this paper, the strength analysis method is introduced for the hull glider among waves considering non-linear hydrodynamic forces. This paper considers that the overall or primary level of the ship structural dynamic loading and dynamic response provided from the non-linear wave forces, and bottom and bow flare impact forces estimated by momentum slamming theory, in which the ship is idealized as a hollow thin-walled box beam using thin-walled beam theory and the finite element method. This method is applied to 40,000 Ton Double-Skin Tanker and attention is paid to the influence of the response of ship speed, wave length and wave height compared with linear strip theory.

Every year in the ocean, various accidents occur frequently and illegal fishing is rampant. Moreover, their size and frequency are also increasing. In order to reduce losses of life or property caused by these, it is necessary to have a means to perform remote monitoring quickly. As an effective platform of such monitoring means, an Unmanned Aerial Vehicle (UAV) is receiving the spotlight. In these situations where marine accidents or illegal fishing occur, main targets of monitoring are ships. In this study, we propose a UAV based ship monitoring system and suggest a method of determining ship positions using UAV multi-sensory data. In the proposed method, firstly, the position and attitude of individual images are determined by using the pre-performed system calibration results and GPS/INS data obtained at the time when images were acquired. In addition, after the ship being detected automatically or semi-automatically from the individual images, the absolute coordinates of the detected ships are determined. The proposed method was applied to actual data measured at 200 m, 350 m, and 500 m altitude, the ship position can be determined with accuracy of 4.068 m, 8.916 m, and 13.734 m, respectively. According to the minimum standard of a hydrographical survey, the ship positioning results of 200 m and 350 m data satisfy grade S and the results of 500 m data do grade 1a, where the accuracy is required for positioning the coastline and topography less significant to navigation order. Therefore, it is expected that the proposed method can be effectively used for various purposes of marine monitoring or surveying.

Effects of iron and/or chelator addition on primary production in the equatorial Upwelling system were studied during the TOGA(Tropical oceans and Global Atmosphere) and EPOCS (Equatorial Pacific ocean Climate Studies) cruises in June and November-December of 1989. Changes in the phytoplankton biomass and the degree of iron stress were estimated using the changes in vivo fluorescence before and after the addition of DCMU, which is an inhibitor of photosynthetic electron transposer system. Nitrate uptake was measured using /SUP 45/N labeled KNO$_3$ to estimate the new production. When samples were taken from the Upwelling area where nitrate concentration was higher than 5 uM, there were significant differences between the control and cheated iron treatments in vivo fluorescence and in nitrate uptake capacity. However, CFC (Cellular fluorescence capacity) did not show any significant difference between the control and treatments until nutrient limitation becomes severse and cells become shifted-down. Outside of the Upwelling area where surface nitrate concentration was low (below 0.5 uM), there was no significant difference between the control and treatments in vivo fluorescence and CFC. It is evident that primary and new production in the equatorial Pacific Upwelling region are limited by the availability of iron. However, the physiology of phytoplankton indigenous to this region does not appear to be iron stressed judging from CFC values.

The triad interactions have been known to be important only for shoaling waves or finite depth wind waves. In deep water, they are insignificant compared with the quadruplet interactions in respect to the evolution of wind waves due to energy transfer among the wave components. However, the triad interactions may be important even for deep water waves because they may closely be related to the wave steepness, which definitely affects wave breaking, drag of air flow over t.'Ie sea, or navigation of ships, especially during the early stage of the development of wind waves. This study reports a series of laboratory experiments, whose data are subjected to bispectral analyses to investigate the triad interactions of deep-water wind waves. It is found that the bicoherence at the spectral peak frequency and the wave steepness are almost directly proportional, indicating that the steep waves with peaked crests and flat troughs are resulted from the triad interactions. Both bicoherence and wave steepness increase with the wave age during the early stage of wave generation and then drop off as the waves grow old. It seems that the energy of the secondary spectral peak developed by the triad interactions during the early stage of wave generation is redistributed to the neighboring frequencies by the quadruplet interactions during the later stage.

The spermatozoa of bagrid catfish, Pseudobagrus fulvidraco are approximately $76{\mu}m$ in length, and a relatively simple and elongated cell composed of a spherical head, a short middle piece and a tail. The ultrastructure of spermatozoa of P. fulvidraco is characterized by the following features. The acrosome is absent as in most teleost. The round nucleus measuring about $1.67{\mu}m$ in length and diameter is depressed with a deep nuclear fossa. The nuclear fossa, the length of which is about three-fifths of the nuclear diameter, contains the proximal and distal contrioles. The two centrioles are oriented approximately $160^{\circ}$ to each other. The filamentous materials give rise to satellite appendages arranged tangentially from the triplets of the distal centriole and the doublets of the anterior end of the axoneme toward the nuclear envelope. The mitochondria are not fused and their number is 20 or more. They are arranged in two or three layers and two rings within the cytoplasmic collar and surround the axoneme. They are separated from the axoneme by the cytoplasmic canal. The axoneme is of the 9+2 microtubular pattern and has inner but no outer dynein arms. The two lateral fins are in the same plane with the two central microtubules, the doublets 3 and 8, which are ultrastructural characteristics of the sperm tail unlike other siluroids lacking the lateral fins.
