This study is concerned with the identification of the concepts and characteristics of the traditional access of small scale fishery and traditional small scale fishery based on the classification of fisheries under Fisheries Law, As we called, these fisheries are the small scale of artisanal fisheries. These traditional small scale of artisanal fisheries have been developed throughout the most coastal fisheries but have never been included the institutional fishery system and policy since industrial fisheries have been exploited. By this reason there was no studies to understand and identify these fisheries as fisheries under category of institutional fishery system. Recently by the Fisheries Law, my Person who desires to operate these fisheries, shall report to the provincial governor and then these fisheries were incorporated into the category of fisheries to be reported. But this case of the administrative practices should be not consistent with the classification of fisheries under Fisheries Law. The traditional access of small scale fishery is a derivative concept of fishery categories under the institutional fakery system Because this fishery under institutional fishery system can not be establish the right of fishing by fishery right system technically but the right of fishing is supported by the fishing access system only. Therefore, It is a mistake for the provincial fishery governor to adopt such a policy that the fishing right of the traditional access of small scale fishery which is different from the fishing based right is restricted by the factors of fisheries to be reported. On the other hand the traditional small scale fishery is coincident with the traditional access of small scale fishery and the common fishery under the style of utilization of fishing gear and fishing gear and methods. But this fishery has never been included the fishery categories supported by the government subsidy policies and considerations and has been remained with indifference during the last few decades. Anyhow the fishing right of these fisheries have been assured under the institutional fishery system, any person who desires to operate this fishery should have a fishing right against the public or private uses of fishing ground such as land reclamations and other coastal zone development. A deprivation of the fishing right of this fishery by the conflicts of these public and private uses of fishing ground is not regarded as appropriate according to the social welfare policy. Also it is the administrative expediency to support the fishing right of this fishery under the fisheries lobe reported.

In order to incorporate correctly the large or local scale circulation in an atmospheric model, a nudging term is introduced into the equation of motion. The MM5 model was used to assess the meteorological values differences in each case, during ozone episode days in Gwangyang bay. The main objective of this study is to investigate the effect of horizontal and vertical flow fields according to the surface and vertical observation data assimilation by upper wind conditions. Therefore, we carried out several numerical experiments with various parameterization methods for nudging coefficient considering the upper wind conditions (synoptic or asynoptic condition). Nudging considering the synoptic and asynoptic nudging coefficient does have a clear advantage over dynamic initialization, therefore appropriate limitation of these nudging coefficient values on its upper wind conditions is necessary before making an assessment. Obviously, under the weak synoptic wind, there was apparent advantage associated with nudging coefficient by the regional difference. The accuracy for the prediction of the meteorological values has been improved by applying the appropriate PBL (Planetary Boundary Layer) limitation of circulation.

This paper proposed signal decomposition and multiresolution representation through wavelet transform using wavelet orthonormal basis. And it suggested most appropriate filter for scaling function in multiresoltion representation and compared two compression method, arithmetic coding and Huffman coding. Results are as follows 1. Daub18 coefficient is most appropriate in computing time, energy compaction, image quality. 2. In case of image browsing that should be small in size and good for recognition, it is reasonable to decompose to 3 scale using pyramidal algorithm. 3. For the case of progressive transmittion where requires most grateful image reconstruction from least number of sampls or reconstruction at any target rate, I embedded the data in order of significance after scaling to 5 step. 4. Medical images such as information loss is fatal have to be compressed by lossless method. As a result from compressing 5 scaled data through arithmetic coding and Huffman coding, I obtained that arithmetic coding is better than huffman coding in processing time and compression ratio. And in case of arithmetic coding I could compress to 38% to original image data.

This study is related with the experimental investigation on the heat transfer and pressure drop characteristics of the fin-and-tube heat exchangers with three different interrupted fins and a plane fin for air-conditioning application. Experiments were conducted accordingly following the appropriate development process. Geometry similitude experiment was introduced to predict the performance of fins, and prototype experiment was also performed to confirm the validity of geometry similitude experimental results. However, these experimental results were limited to the sensible heat transfer characteristics of the heat exchangers. Hence, additional experiment was performed using refrigerant to investigate the latent heat transfer characteristics. This paper presents an appropriate process for the development of a new type heat exchanger. Sensible and latent heat transfer characteristics for each fin configuration is also provided along with the optimal fin configuration.

Extensive research work has been performed on shear strengthening of reinforced concrete (RC) beams retrofitted with externally bonded carbon fiber reinforced polymer (CFRP) in form of strips. However, most of this research work is experimental and very scarce studies are available on numerical modelling of such beams due to truly challenging nature of modelling concrete shear cracking and interfacial interaction between components of such beams. This paper presents an appropriate model for RC beam and to simulate its cracking without numerical computational difficulties, convergence and solution degradation problems. Modelling of steel and CFRP and their interfacial interaction with concrete are discussed. Finally, commercially available non-linear finite element software ABAQUS is used to validate the developed finite element model with key tests performed on full scale T-beams with and without CFRP retrofitting, taken from previous extensive research work. The modelling parameters for bonding behavior of CFRP with special anchors are also proposed. The results presented in this research work illustrate that appropriate modelling of bond behavior of all the three types of interfaces is important in order to correctly simulate the shear behavior of RC beams strengthened with CFRP.

The major issues that higher education has recently faced are the shortage of students of school age, the changing environment of higher education and the evolving technology. These challenges have urged the university facilities and space to be managing more efficient and more effective. This study assures that the strong strategy is to operate more like business while retaining unique higher education values and a sound facilities management system and appropriate budget help to ensure that university facilities are good for student and teacher's demand. With such faith, this study explores the facilities/space maintaining status and the facility management system of national universities and collages. It finds that there are some problems to adapt new managing methodologies in national universities and that there are also some gaps and perceived constraints to effective space management. This study proposes the alternatives for the facilities managing system that involves the improvement of manpower structure, the expansion of budget scale and the establishment of appropriate facility management system. Finally it provides the practical tools for the effective space and facilities management such as space charging, space standards, central timetabling, space utilisation survey and facilities performance indication.
