This study aims to standardize the work classification system in spatial data. Up to now, a systematic standard for constructing process and quality management has not yet been established in Korea, thus, it is possible for the national budget to be wasted. The regulations related to constructing spatial data are also obscure, and absurd for feasible application to reality, which results in a lack of reliability of the quality of spatial data. This study was conducted by investigating and analyzing regulations related to spatial data quality and various literature, including studies on spatial data quality conducted by the NGII. And also, the study was conducted by investigating and analyzing the constructing processes and working methods of major firms that have experience in constructing a GIS for a local governing body. Based on the analyzed data, we standardized work classification and management methodology for control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction, digital orthophotomap.

This paper deals with the FE analysis for the free vibration of sloshing in horizontal cylindrical tank with baffles. We use Laplace equation based on potential theory as governing equation. This problem is solved by FEM using lineal isoparametric elements. We assume that the tank as well as baffles is rigid body and by separating nodes into two at the baffle location, baffle effect is obtained by separating nodes into two at the baffle location. For the calculation of natural frequencies and mode shapes, we introduce Lanczos transformation and Jacobi iteration methods. Numerical results of the first longitudinal and transverse modes, while comparing with literature cited, are very good. In order for the baffle effects on the free vibration of sloshing, various combinations of baffle parameters, which are location, inner diameter and number, are examined.

The aim of this study was to suggest fundamental data for managing forest trail efficiently from the aspect of users near metropolitan city of Daegu, and to reveal the differences in visiting motivation and satisfaction on forest trail between regional users and distant users, which based upon the convenience of accessibility. As a result of questionnaire survey on the users of forest trail, it was revealed that they mostly visited recreational and therapeutic purposes. Most users were also satisfied with forest trail experiences without any differences between groups. Regarding to trail facilities, however, regional users within 30 minutes distances from the trail were significantly dissatisfied with the facilities. It was suggested that improving facilities and programs for recreational and therapeutic purposes should be established for regional users in the policy of self governing body.

Since Modern period which is characterized by the governing of technology and capitalism, the production and aesthetics of building became a main issue of architectural discourse. Morever, Modern architecture tends to be a kind of media in which the visual image of building plays a far more important role than building itself. Institutionalized discipline of Architecture in modern system set aside the dwelling aspect of building and destructed close relationship between dwelling and building. This study analyzes the essential meaning of dwelling with a viewpoint of building and vise virsa in order to have a deep reflection on contemporary architecture and modern crisis of dwelling. For this purpose this study first reviewed linguistic and mythical narratives on the origin of dwelling and building. Secondly, reviewed the thought of Heidegger on dwelling and building and his thinking on authenticity of dwelling. Thirdly, reviewed drastic change of idea and reality of dwelling recent days, especially from settlement to nomad. Lastly reviewed E. Levinas' thinking on bodily dwelling or primordial mode of dwelling before poetic dwelling of Heidegger. With these review we can figure out following things on dwelling and building. Physical building or its visual image can not take the place of dwelling in itself. Dwelling and Building happens simultaneously and understood as an event in life world. Today's alienation of dwelling from building reduced our conception of architecture to a physical setting and mere technique. Building must be a ontological and cultural phenomenon beyond physical building. Nomad in this age of information and globalization may be a new mode of dwelling. But it can not exclude traditional way of dwelling on concrete space, because human being as a physical being can not abandon dwelling place that gives a primordial comfort with and within our body.

Otter boards in the trawl are the one of essential equipments for the net mouth to be spread to the horizontal direction. Its performance should be considered in the light of the spreading force to the drag and the stability of towing in the water. Up to the present, studies of the otter boards have focused mainly on the drag and lift force, but not on the stability of otter boards movement in 3 dimensional space. In this study, the otter board is regarded as a rigid body, which has six degrees of freedom motion in three dimensional coordinate system. The forces acting on the otter boards are the underwater weight, the resistance of drag and spread forces and the tension on the warps and otter pendants. The equations of forces were derived and substituted into the governing equations of 6 degrees of freedom motion, then the second order of differential equations to the otter boards were established. For the stable numerical integration of this system, Backward Euler one of implicit methods was used. From the results of the numerical calculation, graphic simulation was carried out. The simulations were conducted for 3 types of otter boards having same area with different aspect ratio(${\lambda}=0.5,\;1.0,\;1.5$). The tested gear was mid-water trawl and the towing speed was 4k't. The length of warp was 350m and all conditions were same to each otter board. The results of this study are like this; First, the otter boards of ${\lambda}=1.0$ showed the longest spread distance, and the ${\lambda}=0.5$ showed the shorted spread distance. Second, the otter boards of ${\lambda}=1.0$ and 1.5 showed the upright at the towing speed of 4k't, but the one of ${\lambda}=0.5$ heeled outside. Third, the yawing angles of three otter boards were similar after 100 seconds with the small oscillation. Fourth, it was revealed that the net height and width are affected by the characteristics of otter boards such as the lift coefficient.

Inclusion effect of soybean meal (SBM) and fermented SBM (FSM) in extruded pellet for juvenile abalone (Haliotis discus) was compared in abalone farm. Dietary inclusion effect of the combined macroalgae (MA) (Undaria pinnatifida and Hizikia fusiforme) and a single Saccharina japonica on abalone was also compared. Three thousand six hundred juvenile abalone were purchased from a private hatchery and acclimated to the experimental conditions for 2 weeks. Six 5-ton flow-through raceway tanks were used, and abalone were randomly distributed into tanks (n = 600 per tank). Three experimental diets were prepared in duplicate. Fish meal, FSM, corn gluten meal, and shrimp meal and wheat flour and dextrin were used as the protein and carbohydrate sources, respectively, in the FSM diet. MA was also included in the FSM diet. FSM and MA in the FSM diet were substituted with SBM at the expense of wheat flour and S. japonica, referred to as the SBM and SJ diets. The experimental diets were pelletized by an extruded pelleter. Water stability of nutrients in the experimental diets was monitored at 12, 24, and 48 h after seawater immersion. The experimental diets were fed to abalone once a day to satiation with a little leftover for 120 days. The retained crude protein and lipid and ash content of the extruded pellets were changed over all period of time. Weight gain and specific growth rate (SGR) of abalone fed the SBM diet were greater than those of abalone fed the FSM and SJ diets. Weight gain and SGR of abalone fed the SJ diet were also greater than those of abalone fed the FSM diet. The longest shell length, widest shell width, highest shell height, and greatest soft body weight were obtained in abalone fed the SBM diet, followed by the SJ and FSM diets. Proximates of the soft body of abalone were not different among the experimental diets. In conclusion, SBM was a superior protein source to FSM in extruded pellet for growth performance of abalone. Dietary inclusion of a single S. japonica was superior to the combined inclusion of U. pinnatifida and H. fusiforme in the production of abalone.

This Study aims to criticize national pension fund governance reform plan of Korea government and to search for an alternative direction of the reform. Firstly, I examine the theoretical basis of the Korean government reform plan by clarifying limits of application of agency theory to the public pension fund governance. Secondly, I try to reconstruct principles of the public pension fund governance with an alternative theoretical view emphasizing democracy principle. Thirdly, I evaluate the government reform plan with the basis of reconstructed pension fund governance principles. The government reform plan is expected to cause retrenchment of democracy and even political autonomy. It also would make worse the problem of pension fund autonomy from the financial market and the risk of the pension fund caused by market turbulence. Finally I suggest alternative direction of the pension fund governance reform emphasizing the democracy principle. This direction contains constructing co-determination structure of the state and the civil society, escalating controling power of the governing body to the administration body, setting the limits of the roles of the state, attaining of the autonomy from the financial market, strengthening organizational and social accountability.

This paper aims to apply the convergence theory into the minimum income guarantee which forms the moral foundation of the welfare state. The research question of this paper is if the level of minimum income guarantee among EU member states (EU-15) gradually converging into a certain level. For this purpose, Chapter 2 describes the convergence and diversion of welfare states since the Second World War, and chapter 3 explains the historical development of the EU social policies since the Rome Treaty (1957). Chapter 4, which is the main body of this paper, analyzes if the level of minimum income guarantees of EU member states is converging by the coefficient of variation analysis and regression analysis. However, converging trend of the level of basic income guarantee among EU member states has not been proved. In other words, social policy arena still remains strongly in the realm of national sovereign states, irrespective of growing pressure from the supra-national governing body like the EU. It is in line with the Abram de Swaan's argument that "welfare states is nation states" (1994: 110).

The Jeju horse is an indigenous Korean horse breed that is currently registered with the Food and Agriculture Organization of the United Nations. However, there is severe lack of genomic studies on Jeju horse. This study was conducted to investigate genetic characteristics of horses including Jeju horse, Thoroughbred and Jeju crossbred (Jeju${\times}$Thoroughbred) populations. We compared the genomes of three horse populations using the Equine SNP70 Beadchip array. Short-range Linkage disequilibrium was the highest in Thoroughbred, whereas $r^2$ values were lowest in Jeju horse. Expected heterozygosity was the highest in Jeju crossbred (0.351), followed by the Thoroughbred (0.337) and Jeju horse (0.311). The level of inbreeding was slightly higher in Thoroughbred (-0.009) than in Jeju crossbred (-0.035) and Jeju horse (-0.038). $F_{ST}$ value was the highest between Jeju horse and Thoroughbred (0.113), whereas Jeju crossbred and Thoroughbred showed the lowest value (0.031). The genetic relationship was further assessed by principal component analysis, suggesting that Jeju crossbred is more genetically similar to Thoroughbred than Jeju horse population. Additionally, we detected potential selection signatures, for example, in loci located on LCORL/NCAPG and PROP1 genes that are known to influence body. Genome-wide analyses of the three horse populations showed that all the breeds had somewhat a low level of inbreeding within each population. In the population structure analysis, we found that Jeju crossbred was genetically closer to Thoroughbred than Jeju horse. Furthermore, we identified several signatures of selection which might be associated with traits of interest. To our current knowledge, this study is the first genomic research, analyzing genetic relationships of Jeju horse, Thoroughbred and Jeju crossbred.
