  • This fundamental studies on for the productivity improvement and laborsaving of purse seine fishery. Given the difficulty posed from the distortion of net shape caused by the external forces, such as tide, at the time of shooting and pursing, we set the 4 steps of 0, 2, 4 and 6cm/sec in flow velocity in the flume tank for the experiment in order to examine those characteristics. We used two model seines designed on the scale of 1 to 180 based on the power block seine, which is the mackerel purse seine generally used in the near sea of Jeju Island and triplex seine, which is the mackerel purse seine of one boat system fishing expected in the future, for the experiment, and interpreted the characteristics of several motion in water, such as the shape of seine, the change in tension and area during pursing and its the analysis results are as follows. Though the experiment could be conducted up to 6cm/sec of flow velocity that was defined, the experiment could not go on because of the severe distortion in the seine at the flow velocity in excess of 6cm/sec. As for the depth of leadline and reduction rate of side area of seine when the pursing is connected, P seine turned out to be slightly higher than T seine, and the hauling speed and reduction rate of upper area of seine were found similar to each other. The correlation between the hauling time (Ht) and depth of lead line (Dhp, Dht) of P seine and T seine can be expressed by the equation, that is, Dhp=(0.99Pt-7.63)Pt+69.01, Dht=(1.03Pt-7.73)Pt+66.74. The correlation between the hauling time and hauling velocity (Hpp, Hpt) can be expressed by the equation, that is, $Hpp=-0.06Ht^2+0.88Ht+0.78,\;Hpt=-0.05Ht^2+0.81Ht+0.98$ here, Pt is pursing time. And the correlation between the pursing time and the reduction rate of side area (sArp, sArt) can be expressed by the equation, that is, $sArp=-0.48Pt^2+14.79Pt-16.74,\;sArt=-0.45Pt^2+14.56Pt-16.48$. The reduction rate of upper area of seine (tArp, tArt) can be expressed by the equation, that is, $tArp=0.34Pt^2-0.66Pt-0.74,\;tArt=0.34Pt^2-0.27Pt-1.80$. In addition, the correlation between the pursing time and tension of purse line (Tep, Tet) can be expressed by the equation, that is, $Tep=2.79Pt^2+2.26Pt-0.60,\;Tet=2.14Pt^2+8.08Pt-27.50$.

  • The purpose of this study was to put an art counseling program in the elementary school maladjusted child and helped the school life adjustment of the maladjusted child's self-respect and social ability development. For this purpose, picked out 4 people children who are the lowest score in the child where the total score is below 100 points sorted 6 grades of Y elementary school in Daejeon. The art counseling program as a reconstruction of the prior study to meet an object of this study was provided to children in experimental group at the researcher's classroom after school for 12 session, two sessions per week. For analyze the study result. First, for quantitatively analysis of an maladjusted behavior compared pre and post test of conduct of school life adjustments test. Second, for confirm the change of self-respect and social ability development pre and post test and analyzed comparison. Third, recognizing trial state change of an maladjusted children put a KSD pre and post test and analyzed comparison with contents of a picture. Fourth, every session of the qualitative analysis which describes the conduct quality of each child led and the maladjusted child should have been visible what kind of change after the art counseling program execution criminal record, compared. The result of the study is the art counseling program decreased the maladjust conduct of the maladjusted child and is effective to self-respect and social ability development of the maladjusted child. And the art counseling program letting induces the change which is affirmative psychologically with the maladjusted child. As a result, the art counseling program to help the self-respect of the maladjusted child and social ability development, and it will be more effective in the school life adjustment for the maladjusted child.

  • The purpose of this multi-disciplinary convergent study is to establish Image Copyright Archive Model for Museums to protect image copyright and vitalize the use of images out of necessity of research and development on copyright services over the life cycle of art contents created by the museums and out of the necessity to vitalize distribution market of image copyright contents in creative industry and to formulate management system of copyright services. This study made various suggestions for enhancement of transparency and efficiency of art contents ecosystem through vitalization of use and recycling of image copyright materials by proposing standard system for calculation, distribution, settlement and monitoring of copyright royalty of 1,000 domestic museums, galleries and exhibit halls. First, this study proposed contents and structure design of image copyright archive model and, by proposing art contents distribution service platform for prototype simulation, execution simulation and model operation simulation, established art contents copyright royalty process model. As billing system and technological development for image contents are still in incipient stage, this study used the existing contents billing framework as basic model for the development of billing technology for distribution of museum collections and artworks and automatic division and calculation engine for copyright royalty. Ultimately, study suggested image copyright archive model which can be used by artists, curators and distributors. In business strategy, study suggested niche market penetration of museum image copyright archive model. In sales expansion strategy, study established a business model in which effective process of image transaction can be conducted in the form of B2B, B2G, B2C and C2B through flexible connection of museum archive system and controllable management of image copyright materials can be possible. This study is expected to minimize disputes between copyright holder of artwork images and their owners and enhance manageability of copyrighted artworks through prevention of such disputes and provision of information on distribution and utilization of art contents (of collections and new creations) owned by the museums. In addition, by providing a guideline for archives of collections of museums and new creations, this study is expected to increase registration of image copyright and to make various convergent businesses possible such as billing, division and settlement of copyright royalty for image copyright distribution service.

  • As in more than half of the litigated cases, non-conformity of the goods is alleged by the buyer and, hence, the question aries of whether the buyer has given notice within a reasonable time and is thus allowed to rely on the lack of conformity at all, differences in interpreting the meaning of "reasonable time" in Article 39(1) CISG endanger uniformity of international sales law in a core area. This uniform interpretation of the "reasonable time" in Article 39(1) CISG can, however, not be achieved by merely making recommendations to courts and arbitral tribunals that case law from other CISG jurisdictions should be considered. This can at best lead to confusing results. As you know, the determining of reasonable time is depending on the circumstances concerned with the particular case. So the term 'reasonable time' has proven too imprecise due to its flexibility without defined uniform scale to assist the practitioners in a uniform application of Art. 39(1). Therefore I suggested the factors that influenced the determining of the reasonable time. The factors currently influencing whether an Art. 39(1) notice is given within reasonable time in international practice are: any international trade usage and practices, the nature of the remedy chosen by buyer, the nature of the goods delivered and the mode of dealing with the goods.
