This research is to analyze the spatial organization of a traditional rural community and its characteristics, the case of Hanbam village located in the north of Daegu city. The conclusions of this study are as follows; 1. The difference between private space and public space in the residential area of Hanbam village is obvious, and these two spaces are organically related each other by means of road. These spaces have some spatial characteristics of organization, such as center, hierarchy and sequence. 2. The private space consists of a residence module and a farming area in the settlement, and it is clearly farmed by the firm fence of rocks and by surrounding roads. Fruit-bearing trees such as Pyrus pyrifolia, Cornus officinalis, Diospyros kaki, Juglans sinensis are planted at the boundary. And most of residences are composed of a building, a inner court and farming fields. 3. The public space for the community mainly functions as ‘a meeting place’for residents, and consists of recreational spaces, ceremonial spaces, community facilities, and social facilities. Among these, Jeong-ja(pavilion), Seong-an Soop(forest) and Dae-chong(building for common use) are of great cultural value as important traditional spaces. 4. Two kinds of road are commonly fecund in the village; spontaneously generated one and planned one. This is straight inner streets and access paths to the village, and that is curvilinear alleys which are connected to Dae-chong, the core of village. Also stone walls and climbing plants on them are major elements of village landscape.

In this paper, a self-organization framework for swarm systems in three dimensions is presented. The framework uses artificial potential functions(APFs) to direct the robots toward the goal as well as to keep them in a swarm system. This research extends conventional APFs used for self-organizations in two dimension environment to three dimensions. In three dimension environment, the ground potential for the boundary surfaces that commonly appear in three dimension environments is proposed. Accordingly, the comparison between the paths without and with the ground potentials shows the necessity and effect of ground potentials. Extensive simulations are given to show the effectiveness of the extended potentials and various properties in three dimension environments.

Recent information and communication technologies have already opened up new prospects for technology groups, especially in a knowledge-based society. A contemporary technological era, which can be stated as the hyper-connective Internet of Things surpassed the traditional service pattern and innovation pattern by conveying personalized, localized, and con-text-aware services close to different actors and users. The conventional boundary of the organization is disbanding as well as traditional innovation and research & development limits. This research article conducts a preliminary study about the hyper-connective Internet of Things technology portent with innovation 3.0 version based on an extended technological organization environment framework (E-TOEF). This article discusses the emergence of innovation 3.0 as a paradigm shift from a manufacturing paradigm to an actor-oriented paradigm. There is a need to shift from a manufacturing mindset to more user ergonomics and be aware of the potential of hyper-connective IoT on the revolution of innovation patterns to be more cooperative, open, and user-centered. Besides, this article would strain some conceptual approaches for the next-generation innovation paradigm known as "hyper-connective IoT" entitled innovation 3.0. This new innovation version goes beyond open innovation and undeniably clearly beyond closed innovation which was an earlier version.

The landscape structure of the both pre-industrial and industrial cities should be influenced to the topographical feature , religious thoughts, political ruling system and history. In the major socio-cultural factors in the pre-industrial townscapes in korea, the Feng - Shui(poongsu) which is an acient human settlement organization system based on the “Yin - Yang” principle and “Five Elements” and “Chryaegogong”system were the most important factors to the formation of traditional town scape in Korea. The landscape during the Japanese colonial periods were basically reorganized through change of “Boundary”, “Center” “Direction(path)” and “Domain” which were expressed by distinct traditional townscape in Yi dynasty. The physical shapes, meanings and behaviors of townscape were expressed properly of the intention of the colonization. As changes to the mordern industrial cities, the townscape had been amended landscape elements of the Japanese imperialism to an ideology of rebirth nation. Also as changes to the modern industrial cities, “Boundary”, “Center”, and “Domain” spreaded into the suburbs by funtionalsm and these were expressed an incoherent value system which were the advancement of growth, pursuit policies as well as an advancement of science techniques.

In 2002 Thailand was faced with severe flooding in the North, Northeast and Central parts of the country caused by heavy rainfall of the monsoonal depression which brought about significant damages. According to the report by the Ministry of Interior and the Ministry of Agricultural and Co-operatives, the total damages were estimated to be about 6 billion bath. More than 850,000 farmers and 10 million livestock were effected. An area of 1,450,000 ha of farmland in 59 Provinces were put under water for a prolonged period. Satellite imageries were employed for mapping and monitoring the flood-inundated areas, flood damage assessment, flood hazard zoning and post-flood survey of river configuration and protection works. By integrating satellite data with other updated spatial and non-spatial data, likely flood zones can be predicted beforehand. Some examples of satellite data application to flood dis aster mitigation in Thailand during 2002 using mostly Radarsat-1 data and Landsat-7 data were illustrated and discussed in the paper. The results showed that satellite data can clearly identify and give information on the status, flooding period, boundary and damage of flooding. For comprehensive flood mitigation planning, other geo-informatic data, such as the elevation of topography, hydrological data need to be integrated. Ground truth data of the watershed area, including the water level, velocity, drainage pattern and direction were also useful for flood forecasting in the future.

An object oriented programming(OOP) framework is presented to solve plane elastostatic contact problems by means of the boundary element method(BEM). Unified modeling language(UML) is chosen to describe the structure of the program without loss of generality, even though all implemented codes are written with C++. The implementation is based on computational abstractions of both mathematical and physical concepts associated with contact mechanics involving geometrical nonlinearities and the corner node problems for multi-valued traction. The overall class organization for contact analysis is discussed in detail. Numerical examples are also presented to verify the accuracy of the developed BEM program.

The spanwise growth of turbulence structures in turbulent pipe flow was investigated using the direct numerical simulation data of Re_𝜏 = 544, 934 and 3008. Two-point correlations and pre-multiplied energy spectra of streamwise velocity fluctuations were examined along the spanwise direction. The arclength direction is defined as r𝛳, which is useful for an analogy with the spanwise direction for channels or boundary layers; here, r and 𝛳 are the radial distance from the core and the azimuthal angles, respectively. Both analyses showed that the arclength scales increased with increasing the wall-normal distance. It showed that the coherent structures were confined in the core region due to the crowding effect of a circular pipe geometry. The pipe flow simulation could describe a realistic geometrical flow along the azimuthal direction, unlike the simulations of turbulent channel or boundary layer flow using periodic boundary conditions along the spanwise direction. The present results provided the spanwise organization of energy-containing motions over a broad range of scales in turbulent pipe flow.

The sea of north-east Asia is biologically interrelated and one country's mishap in the management of fisheries could have a critical effect upon the other. Accordingly under the TAC system adopted by all the countries of Korea, Japan and China, the mismanagement o( trans-boundary fish stocks under the provisional fisheries agreement prior to the delimitation of EEZ could lead to the irrevocable depletion of fisheries resources in case of absence of close cooperation among the countries concerned. To tackle the problems above, it is necessary, from a short term perspective, to promote the combined efforts to do researches on fisheries resources, find ways to improve the transparency of fisheries management, adjust the fisheries management regulations of each country, standardize fishing gears and methods, and exchange fisheries-related statistics and data for socio-economic analysis and strengthen joint research activities for the mutual benefits. From a longer term prospective, regional fisheries organization need to be set up to oversee the whole area of north-east Asian sea. The organization as such could play a role in adjusting the conflicting interests of Korea, Japan and China, and efficiently manage the fisheries resources, which is complex and challenging in nature. In addition, unlike China, the historical fisheries relationship between Korea and Japan, spirit of reciprocity and the Article 62 of the United Nations Convention On the Law Of Sea need to be taken into account when seeking for fisheries cooperation between the two countries through the international specialization. In other words, the data obtained through the joint researches on the fisheries resources for the specific ocean along with such factors as capital, labor, fisheries technology and consumption of fish products could be used to assign the specific sector of fisheries to the country who has a comparative advantage, thus achieving the mutually benefiting results Up to the present, concerted efforts by Korea, Japan and China on the fisheries cooperation have been consistently made, but the results have yet to be materialized, It is also beyond doubt that governmental consultations among the countries should be made on a consistent basis, but non-governmental organizations' exchanges and related joint researches will more likely help bring about the desired fruition in a shorter time.
