  • Soil structure and organic matter have been known to strongly affect water flow and solute transport, yet little information is available concerning soil hydraulic properties related to soil physical and chemical properties in the forest site. The purpose of this study was to quantify the spatial variability and spatial correlation of the measured parameter values from the plots established with the rainfall simulator on Japanese larch(Larix leptolepis) dominated site in Kwangju. Kyunggi-Do. Measurement of soil water flux and retention were made with the inherent soil texture, soil structure, and organic matter. The method was based on the observation that when water was applied at a constant rate to the soil surface on each plot. The method was simple to apply and consists of following steps: (i) Wet the soil from a rainfall simulator with several known discharge rates on a relatively leveled soil surface with and without organic matter. (ii) Once the borders of the ponded zone were steady, saturated hydraulic conductivity( $K_{s}$) and the matric flux function(F) was evaluated from a regression of flux vs. the reciprocal of the ponded area. A conductivity of the form $K_{i+}$$_1$ $_{c}$= $K_{i}$( $_{c}$) [1-d /dz] where flux continuity implies. For this, continuity of matric potential at the interface at all times are as follows: $_1$( $Z_{c}$) = $_2$( $Z_{c}$) = $_{c}$ for steady state intake from water ponded on the soil surface. Results of this investigation showed the importance of understanding spatial variability in wide differences of water retention and saturated hydraulic conductivity with respect to pore geometry and organic matter contents which influenced the water flux throughout the soil profile.l profile.ile.

  • The purpose of this study was to investigate students' ontological categories about rocks and the earth's crust and plate tectonics. A total of 169 high school students in the first grade were involved in the study, and in order to extend the boundary and tendency of the research, structuralized questions and coding frame were generated. Additionally, the results from all students were codified in four levels according to coding frame (matter, transformation, proto-process, and process). Followings are the results. First, the ontological categories of students about the concepts of this research were classified dominantly into a matter and transformation within the boundary of 67% of rocks, and 75% of the crust. The propensity of plate tectonics in terms of ontological category were analyzed by being codified into 68% of process category which proved to have relatively process-oriented perspective. Secondly, the inclination to allocate ontological categories of each students in terms of field concepts were confirmed in 16% and 31% per each student that were codified into process categories and matter categories. Most students that were codified into matter category responded to high tendency to view the world as a combination of simple substances. Moreover, the students had ontological faith that speculates only through a state or an incident in terms of concepts that form a structure of knowledge.

  • The meticulous figure painting is one of the wonders of traditional Chinese painting and has blossomed in art history with its unique and interesting style. The period from the Warring States period to the Song and Yuan dynasties was a glorious period in its history, after which it tended to decline due to changes in painting materials and many socio-historical reasons. The extensive cultural exchanges in the world today, the penetration of Western values and the expansion of information technology have brought a huge impact on Chinese meticulous figure painting, which has developed an active way of thinking and expression after absorbing certain elements of Western culture and thought on the basis of inherited tradition. Contemporary Realistic Figure painters continue to explore new developments in meticulous figure painting in the contemporary context, and give contemporary meticulous figure painting a new cultural and ideological connotation, forming a new look that meets the requirements of the times, with richer and more lively content, subject matter and formal language. Traditional meticulous figure painting is characterised by a highly refined use of line and coloring composition. Contemporary meticulous figure painting focuses on the use of purely formal language and the expression of the personality of the creative subject, with a new outlook on the world of painting. In the contemporary multicultural context, new formal language and methods of expression are constantly being explored to create a new look. In the process of development, contemporary meticulous figure painting has merged the best qualities of traditional and contemporary culture, making it an art with a subtle language, rich in meaning and with the charm of the times and oriental characteristics. The author in the form of contemporary fine brushwork figure painting language as the research object, explore new form of fine brushwork figure painting, and in the contemporary society and multicultural context factors. Innovation, enrich and develop new forms of art language of contemporary social form and aesthetic temperament and interest.

  • Objective: This study was conducted to evaluate the effects of feed processing and particle size on growth performance, nutrient digestibility, carcass characteristics, and gastric health in growing-finishing pigs. Methods: A total of 360 growing pigs (22.64±0.014 kg initial body weight [BW]) were allocated to 1 of 6 treatments with 6 replicates by BW and sex, and 10 pigs were housed in one pen in a randomized complete block design. The BW and feed intake were recorded to calculate growth performance. For the digestibility trial, a total of 24 barrows with an initial BW of 33.65±0.372 kg were split into 6 treatments with a completely randomized design. Dietary treatments were designed by a 2×3 factorial arrangement of treatments based on two main factors, particle size (600, 750, 900 ㎛) and feed form (mash and pellet) of diet. Experimental diets were formulated to contain the requirements of the NRC (2012). Results: The BW and average daily gain were not changed by dietary treatments, and the feed intake of finishing pigs (wks 6 to 12) was increased when the pigs were fed a mash diet (p<0.05). For the overall period, the feed efficiency of pigs was improved with the pellet diet (p<0.01) and reduced particle size (p<0.05). The pellet diet had effects on increasing crude fat digestibility (p<0.01) relative to a mash diet, but there was no considerable change in dry matter and crude protein digestibilities by dietary treatments. In the evaluation of gastric health, a trend for an increased incidence of keratinization in the esophageal region was observed as particle size decreased (p = 0.07). Conclusion: Feed efficiency could be improved by pellet diet and reduced particle size. Nutrient digestibility, carcass characteristics, and gastric health were not affected by feed form, and particle size ranged from 600 to 900 ㎛.

  • This study was conducted to investigate the effect of feed particle size and feed form on growth performance, nutrient metabolizability and intestinal morphology in broiler chickens. This experiment was a 2${\times}$2 factorial arrangement including two feed particle sizes (fine and coarse) and two feed forms (mash and pellet). A total of two hundred and eighty eight day-old male Arbor Acre broilers were used in this six week experiment. Birds were randomly allotted to four dietary treatments with six replicates per treatment and twelve birds per replicate. The results showed that pelleting diets resulted in greater ADG (p<0.01), greater ADFI (p<0.01) and lower feed to gain ratio (F/G) (p<0.05) during starter, grower and overall period. Also, pelleting improved both apparent metabolizable energy (AME) (p<0.01) and the apparent metabolizability of crude protein (p<0.05) and organic matter (p<0.05) regardless of the phase. Reduction of feed particle size enhanced AME (p<0.05) during d 19 to 21. Increased villus height (p<0.05) and crypt depth ratio (p< 0.05) within duodenum, jejunum, and ileum were observed in birds fed the pellet diet compared with those given the mash diet. In conclusion, results indicated that feed pellets might enhance performance by improving nutrient metabolizability and digestive tract development.

  • Le Corbusier (1887-1965) is known as a great architect ranking with such master architects as Frank Lloyd Wright and Mies van der Rohe who produced great architectural achievements in an era from the dawning to the maturity of the modem architecture. His works are marked for their peculiarity in expressing his architectural concept as perceived through his artistic sensibility. He has brought the form of his architecture to perfect through the influence of Purism. His architectural concept has instigated him to construct the relations between structure, form and the notion of space through the 'Dom-ino' structural system and the 'Five Principles of the Modem Architecture.' As a result, he has become such an architect as has ripened his works by adopting the 'Modulor' for human measurement. During the decade from 1929 to 1939, he made public the 'Museum of Unlimited Growth' programs in an attempt to give a concrete form to his concept of 'unlimited space' spreading to all directions, which was actually visualized by the constructions of three art museums, located Ahmedabad and Chandigarh in India and Tokyo in Japan. Although a number of researches have so far been publicized on the works and the architectural ideas of Le Corbusier, no systematic research has yet been released on the idea of 'Museum of Unlimited Growth' as a matter of fact. Therefore, this study has set its purpose to grasp the peculiarities of his exhibition space design through an analysis on the characteristics of the 'Museum of Unlimited Growth' so designed as to reflect the concept of a space, which is centrifugally growing. With this purpose in mind, this research is also to suggest how the design of the 'Museum of Unlimited Growth' would influence the modem museum exhibit space. The contents of this study comprise the consideration on the early ideas of Le Corbusier, the typical features of the growing museum and the analysis as well as the integration of his works.

  • This paper examines the ink on paper technique that is being used in the animation works by the Canadian filmmaker Michēle Cournoyner from the National Film Board of Canada. It also discusses how in her animated film "Soif"(2013) this technique has been applied to compose the narrative significance and symbols through the use of metamorphosis as a form of artistic expression. Cournoyner had used the ink of paper technique as a means to abandon realistic representations of movement, and in "Soif" through expressive use of metamorphosis, portrayed changes of images in character and object not through chronological order of narrative flow, but through the body of the female character, which had been represented by the improvisation of the ink on paper technique in order to express the surrealistic and unconscious state of mind in animation. Also, the use of Surrealist automatism had been incorporated to evoke the film towards a form of abstract and metaphysical expression, which in terms of expression and technique connects with the character in the animation to give emphasis to its relevancy with the subject matter of the work.

  • The purpose of this paper is to define the spatial scope and landscape structure of the capital city of Shilla Dynasty. We have tried to analyze the locational characteristics, the location and landscape form of the Yonggang-Dong pond site which was assumed a part of a king's place, and had the important implicitness in delineating the spatial scope of capital city of Shilla Dynasty. The research took the theory of landscape cognition as a tool, and processed with the book review related simultaneously. The results of study are as follows; 1) It has been almost conformed that the Yonggang-Dong Pond Site was a part of the North Palace of Shilla Dynasty, and it took the form of fully enclosed by the forest, such as the names of Imjungsu and Gosungsu, and so on. This fact has leaded to the special landscape form of 'Forest with Palace' that is an similar pattern of Forest with Tumulus, Forest having Well, Forest having Well, Forest having Mountain. Each of them is symbolizing the place of holiness in the Shilla Dynasty. 2) The Yonggang-Dong Pond site and its surrounding forests made them together be the north border of the Capital City of Shilla Dynasty. This fact made it possible to consider the form of landscape of the Najung Forest with Posugjung Pavilion as the same on which was on the southern border of the city. 3) The above mentioned facts lead to clues that the border of the capital city of Shilla Dynasty does mean that it was not the mere functional one, but symbolic one. Thus, this paper suggests that the spatial scope of the capital city of Shilla Dynasty should include not only the area of block system, but also the surrounding natural area of mountains, forests, and so on, including the artificial elements of palace and pavilion. 4) This type of borders with the natural elements show basically the different type and function. We could find out some examples from China's and Japan under the same block systems and in the same era. It should be more identifiable in the form and the meaning of landscape of the capital city of Silla Dynasty in ancient Korea.

  • Wireless community networks (WCNs) are considered another form of ownership of internet protocol (IP) networks, where community members manage and own every piece of equipment in a decentralized way, and routing for traffic is done in a cooperative manner. However, the current routing protocols for WCNs suffer from stability and scalability issues. In this paper, an enhanced routing protocol is proposed based on the optimized link state routing (OLSR) protocol to meet the standards of efficiency in terms of stability and scalability. The proposed routing protocol is enhanced through two phases: multicasting expansion and multipoint relay (MPR) selection based on an analytical hierarchical process (AHP). The experimental results demonstrate that the proposed routing protocol outperforms the OLSR protocol in terms of network control overhead and packet delivery ratio by 18% and 1% respectively.
