This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.

This paper examines current developing status of space law as defined in terms of its unique principle that "the utilization of outer space for all mankind's interest". As commercialization of space activities has brought about heated debate on its legitimacy with respect to that principle, space law has come to witness a dual situation. One is the realization of that principle in establishing commercial space activities system where all mankind's interest is respected through the non-discriminatory distribution mode of space benefit. In satellite telecommunication system, the INTELSAT Organization assures its public service policy while protecting itself against a competition from separate systems. For remote sensing, commercialization of LANDSAT Systems promoted since 1984 seems not to affect present non-discriminatory distribution of data and information obtained. On the other hand, active participation of private entity aiming at commercial profit enables national government to manage more effective control and supervision of those activities with a view to promoting national interests. Also, newly developed private rules and regulations are emerging in business relations about commercial space activities. Extended capacity of national government assuring its national interest in production and distribution of international resources that is outer space, and regulation of space activities by newly developed rules and customs provoke a concern about a identity problem of space law. The best way to summarize this perspective might consist in saying that non space law regulations, which are not assumed as aiming at the promotion of all mankind's interest, are confirming their role about space related activities. For those reasous, we are now facing a developing status of space law as developments of commercial space activities continues.

This study is aimed to compare stock assessment models which are effective in assessing red snow crab Chinonoecetes japonicus resources and to select and apply an effective stock assessment model in the future. In order to select an effective stock assessment model, a process-error model, observation-error model, and a Bayesian state-space model were estimated. Analytical results show that the least error is observed between the estimated CPUE (catch per unit effort) and the observed CPUE when using the Bayesian state-space model. For the Bayesian state-space model, the 95% credible interval(CI) ranges for the maximum sustainable yield (MSY), carrying capacity (K), catchability coefficient (q), and intrinsic growth (r) are estimated to be 10,420-47,200 tons, 185,200-444,800 tons, 3.81E-06-9.02E-06, and 0.14-0.66, respectively. The results show that the Bayesian state-space model was most reliable among models.

This study analyzes the creation process of local cultural contents that appears in the Maeul-mandeulgi by utilizing the "Village Rituals" handed down from village. The purpose is to analyze the social values and meanings they represent. For this purpose, a qualitative research method using Chilgok-gun Yeong-ori was applied and analyzed through Lefebvre's the production of space theory. Residents began to recognize the necessity of projects such as Maeul-mandeulgi to overcome the community crisis, and attempted to change the perception of existing village rituals. Residents began to recognize the need for projects such as Maeul-mandeulgi to overcome the community crisis, Attempts to change the perception of the existing village rituals resulted in spatial practice. The new cultural contents were created by adding a playful element to the existing Cheonwangje, and thereby strengthening the identity of the village. This resulted in the reproduction of the village as a new cultural space, but it showed the reproduction of the space in which the alienation occurred due to excessive physical expansion. However, through this process, villagers increased their sense of belonging and increased their satisfaction, which showed the process of being produced as a space of representation that strengthens the sense of community.

Background and objective: Urbanization caused a reduction in urban green space and a lack of community spaces. An attempt to solve these problems, urban gardens, have become popular and are currently being implemented in various downtown areas. However, urban gardens have some inadequate aspects from a visual or landscape perspective. The goal of this study was to examine the possibility of an aesthetic and productive garden space by introducing cultivation methods through the planting system design process. Methods: The design process using plants was classified and presented to suggest the importance of the landscape and aesthetic value. An urban garden space was designed according to the perspective of 'production scenery' and 'participation aesthetics'. According to the characteristics of the plant, urban gardens were divided into vertical type (corn, millet, sorghum), climbing type (kidney bean, cucumber, bitter gourd), and runner type (melon, watermelon, peanut). After classifying plants according to the shape of the root, the structure supporting climbing was installed and the crops were cultivated in an upright form with a tunnel. Results: In the designed cultivation, each crop cooperates, without invading each other's space. Compared with the conventional cultivation, there was little difference in production, and management was made more convenient since weed outbreaks were effectively suppressed while runner type crops cover over the land's surface. Since the positions of each crop are clearly distinguished, the aesthetic value is improved by offering a sense of rhythm with a balanced design. Conclusion: The results suggest that the cultivation methods through the plant system design process have aesthetic as well as productive value, and the design using plants, an infinite living resource, could lead to an expansion of the design field. Moreover, it would enable a sustainable symbiosis between industry and environment. There is potential for the design industry to make significant progress through collaboration with agriculture, horticulture, and landscape architecture.

Adequate conditions of water content and aeration of container media are major environmental factors in the production of pot plant. This experiment was carried out to find optimum physical property of media for the production of small potted Ardisia in capillary mat irrigation system. The plant materials used in this experiment were Ardisia pusilla and Ardisia japonica. Seven substrates were formulated by blending perlite or fresh rice hulls at 20%, 40%, 60% (v/v) with sphagnum peat. Total pore space (TPS) increased by blending sphagnum peat with fresh rice hulls, but decreased by blending sphagnum peat with perlite. As fresh rice hull (FRH) and perlite content increased, air filled pore space (AFP) of substrate increased but container capacity (CC) decreased. Substrate blended with fresh rice hull was higher AFP than blended with perlite and the rate of increase was higher for FRH-containing substrate. As AFP increased, the $CO_2$ concentration in the pot decreased and the $CO_2$ concentration of substrate blended with FRH was higher than blended with perlite. The fresh and dry weight of Ardisia pusilla and A. japonica was the highest in the substrate contained 60% FRH, but the ratio of shoot dry weight to root dry weight was the lowest. The optimum total pore space, air-filled pore space, water holding capacity of substrate for the growth of Ardisia pusilla and A. japonica in the capillary mat irrigation system were 82.8%, 25.6%, and 57.2% respectively.

A bench scale slurry bubble column reactor (SBCR) with active-Fe based catalyst was developed for the Fischer-Tropsch synthesis (FTS) reaction. Considering the highly exothermic reaction heat generated in the bench scale SBCR, an effective cooling system was devised consisting of a U-type dip tube submerged in the reactor. Also, the physical and chemical properties of the catalyst were controlled so as to achieve high activity for the CO conversion and liquid oil ($C_{5+}$) production. Firstly, the FTS performance of the FeCuK/$SiO_2$ catalyst in the SBCR under reaction conditions of $265^{\circ}C$, 2.5 MPa, and $H_2/CO=1$ was investigated. The CO conversion and liquid oil ($C_{5+}$) productivity in the reaction were 88.6% and 0.226 $g/g_{cat}-h$, respectively, corresponding to a liquid oil ($C_{5+}$) production rate of 0.03 bbl/day. To investigate the FTS reaction behavior in the bench scale SBCR, the effects of the space velocity and superficial velocity of the synthesis gas and reaction temperature were also studied. The liquid oil production rate increased upto 0.057 bbl/day with increasing space velocity from 2.61 to 3.92 $SL/h-g_{Fe}$ and it was confirmed that the SBCR bench system developed in this research precisely simulated the FTS reaction behavior reported in the small scale slurry reactor.
