The Landscape of the Bibo Geomancy is generally showed in Korean traditional settlement. The tradition of the Bibo Geomancy was given much weight in the Korean geographic history of life, so it could be a important research theme. The discussion in my dissertation, 1 insist on that, a comment of the Bibo together with a comment of the selection of proper sites composed as axis in Korean geomancy. As a grounds basis of an argument, 1 described on the concept and the composition of the Bibo Geomancy, the backgrounds of the theory, the historical changes of the Bibo Geomancy in Korea, the form and the function of the Bibo and the comparison with the Bibo-Geomancy of the north-east Asia.

In the dissertation, Bibos are discussed as landscape features in the geographical context of Youngnam Region. The bibo tradition in Youngnam Region began with the incorporation of temple structures in Shilla and Kaya kingdoms, and spread throughout the country during the period of Unified Shilla. In Korea Dynasty, the diffusion of temple Bibo gained momentum, because Buddhism was worshipped as national religion. Then came a sea change in the Bibo repertoire with the replacement of Buddhism by Confucianism as an ideological prop for Chason Korea. The retreat of Buddhism led to the popularization of feng-shui motifs in Bibo strategy. The centers of the diffusion of the logic of bibo were major towns such as Kyongju, Ahndong, Sangju, and Chinju. The diffusion process continued top-down to mid-sized towns, and to the bottom of small villages. What sustained the hierarchical diffusion of Bibo attributes was myriad of transportation lines. The main artery of the diffusion in Korea Dynasty was that connecting Kaegyong to Kyongju. That same function was performed by the royal road running from Seoul through Sangju, Milyang, and to Tongrae. In the age of modernization, the feng-shui and Bibo landscapes have lost their original aura. They have suffered from the ruthless attacks of the Enlightenment logic of science. However, the elan vital of feng-shui and Bibo are still visible and strongly felt in the countryside. From field experiences, one can notice that the Bibo landscapes are tightly integrated into the rural way of life. The durability of the traditional geomancy shows us the beauty of the harmonious interplay between Youngnam people and the nature.

This research surveyed the native resources which BiBo(replenishing shortages by helping each other) landscapes have been preserved by aiming at the village settlement spaces of five cities and counties in Gangwon Youngseo province. This research reveals that BiBo landscape patterns of 41 village forests, 23 BiBo symbols, and 6 BiBo ponds were surveyed. The village forests are all 41 places, and were mainly made on the plains in front of villages. BiBo functions of the forests were in the order of the land obstructing the view of the mouth of a river which is the most as 13 places, the land obstructing the view of the mouth of river, situation complements, village protection, and protection against wind. Bibo symbols were all 23 places. Towers, stone towers, menhirs, and Maitreya stones were 12 places, Jangseungs(a signpost raising on the entrance of the village or a temple) were 6 places, Sotdae(a pole raising at the entrance of the village as the symbol of a board or a village protecting deity) was 1 place, and the others were made multiply in 4 places. Bibo symbols were located at 21 places in front of villages. The village protection in Bibo functions was 6 places. 6 Bibo ponds were surveyed. Most Bibo ponds were made for earth power leakage prevention.

The traditional village forests in Korea such as Dangsan forests and Bibo forests form unique cultural landscape and they are national cultural assets with histories of more than several hundred years. It is important to have sustainable right to enjoy cultural heritage as well as maintaining its authenticity. Cultural assets are meaningful only when they are managed to succeed to next generations. Dangsan forests and Bibo forests need to be named properly and recognized by society as a precious cultural heritage for many generations to come in order to claim the value as traditional cultural landscapes in Korea. The traditional village forest in Dangin-ri, Wando-gun was composed of a Dangsan forest and five Bibo forests. Although this traditional village forest is large in size, it was not on the report of Cultural Heritage Administration(2005) investigated for 'Village forest of island region in Jeollanam-do'. The objective of this study was to investigate the characteristics of the traditional village forest in Dangin-ri to grant correct name and to enhance its value. In this study the characteristics of a Dangsan forest and five Bibo forests were investigated from 2006 to 2013 for physical features such as size, shape, location, tree species composition, and diameter at breast height(DBH), as well as cultural aspects and tradition. Currently the naming and designation of natural monuments by the cultural heritage administration(CHA) is based on the rule enacted in 1934. Many Dangsan forests were named as evergreen forests. This type of names does not represent the meaning of traditional village forest. It was suggested that this traditional village forest is to be named as 'Dangsan Forest and Bibo Forests at Dangin-ri, Wando-gun'. This traditional village forest needs to reclaim authenticity and rebuild its original appearance by restoration of the disturbed areas, especially in Bibo forest I.

Currently, the natural monument system of Korea for naming and designation of natural monuments is based on "Chosun Natural Monument Conservation Acts for Treasure, Ancient Landmark, and Natural Beauty" enacted in 1934 during Japanese colonization period. The framework of natural monument system is still in effect, which is pointed out as a problem. The Dangsan forests and Bibo forests are Korean traditional cultural resources representing countryside of Korea. Cultural Heritage Administration follows and relies on the 'Limsu of Chosun' (1938), a report written by a Japanese, for naming and classification of natural monuments. A Dangsan forest at Yesong-ri was named "Yesong-ri evergreen forest" in 1938. They followed the naming system of "evergeen forest" until today. The objective of this study is to review the issues and problems of 'Limsu of Chosun' and natural monument naming system begun during Japanese occupation period, and suggest an alternative to the current situation where naming natural monument accordingly without discretion. Eighteen dangsan forests bibo forests were selected for examination and analysis. The names of the dangsan forests bibo forests were evaluated to find out whether various aspects of the forests are reflected in the name. The study suggests that many forests and old trees designated as natural monument should be named as "~Dangsan forest", "~Dangsan forest Bibo forest", or "~Dangsan tree" with consistency accordingly. The new names will bring a momentum to overcome the limitation of natural monument naming system continued since Japanese occupation period, and also enhance the value of Dangsan forests and Bibo forests as Korean traditional and cultural landscapes.

This paper proposes a nonlinear fuzzy PID controller with variable parameters to improve slow rising time and divergence occurred by limited input spaces and a resultant limited control input during fuzzification in a fuzzy PID controller with fixed parameters, and describes the design principle and tracking performance of a proposed fuzzy PID controller. The parameters of a proposed controller are adjusted by the stability conditions derived from 'small gain theorem' and satisfy the BIBO stability of overall control system.

Beopseongpo has been one of the most thriving ports of the Jeolla region since the Goryeo Dynasty (918-1392). During the time of King Seongjong (r. 1469-1494) of Choseon Dynasty, a navy garrison had been deployed and the port was named Beopseongjin, as recorded in the 1485 edition of Grand code for state administration (Gyeongguk daejeon). Dangsan forests and Bibo forests have been maintained by local residents since hundreds of years ago. Dangsan forests have been applied to the scale of government and public offices. The objectives of this study were to understand the characteristics of the "Wooded Fortress of Beopseongjin in Yeonggwang" as "Scenic Site No. 22", and to investigate the conservational problem of the wooded fortress of Beopseongjin and seashore. The "Wooded fortress of Beopseongjin in Yeonggwang" consists of a Dangsan forest and two Bibo forests. But, the presence of the Dangsan forest has not been well known to the public. Although the wooded fortress has been somewhat disturbed by cultural activities, the Dangsan rituals have been held until the present every January 15 by lunar calendar. On the other hand, the seashore in front of Beopseongpo plays an important role as a scenic view. It was one of the reason that the "Wooded fortress of Beopseongjin in Yeonggwang" had been designated as a national cultural property of "Scenic Sites". However, the sandbar was reclaimed in 2009 to build commercial buildings. An integrated plan should be prepared to conserve the landscape of "Wooded fortress of Beopseongjin in Yeonggwang", which requires close partnership among local residents, experts, and local government. At present, four new buildings have been built. Although we have lost the sandbar, it is indispensable to secure the visibility of Wooded Fortress of Beopseongjin at the entrance of the village.

In this paper, Fengshui Theory Analysis Eunpyeong-New Town. The analysis frame is man and nature integrated, suit one measures to local conditions, analysis of macro environment site selection, analysis of micro environment site selection, analysis of traffic lines, orientations of residential analysis. The result is as follows: The analysis of the macro environment site selection of Eunpyeong-New Town at Northwest Mountain shape is open, so in the winter exposure of the northwest there is wind. Therefore, according to Fengshui there is a bad pattern formation. Analysis of the macro environment site selection has four animal frames seperated into two districts. The result is district one has "bad" ground. District two uses Bibo to restore small brooks so the formation has "good" ground. Finally, we use Fengshui of Bibo to propose solutions.

This paper describes the design principle of a fuzzy PID controller with fixed parameters, proposes the simulified form of a fuzzy PID controller to increase the computational efficiency and analyzes stability of a proposed fuzzy PID controller. After a detailed stability analysis using ‘small gain theorem’, a simple and practical sufficient condition for the BIBO stability of the overall feedback control system is derived. The derived stability condition offers a calculation method to obtain parameters of a fuzzy PID controller from parameters of a stable PID controller. Finally several computer simulations are executed to confirm the effectiveness of the fuzzy PID controller with fixed parameters.
