This study was carried out on scientific conservation treatment based on material characteristics, provenance interpretation, and deterioration diagnosis for seven-storied Jungwon Tappyeongri stone pagoda in Chungju. As a result, main rock of the pagoda is biotite granite with magnetite-series (average $5.86{\times}10^{-3}$ SI unit), containing partly basic xenolith, pegmatite veinlet and feldspar phenocryst. As a result of the provenance presumption of the host rock, a rock around the Songgang stream was identified the same origin. Therefore the rock is appropriate for materials of the pagoda restoration. The deterioration assessment suggested that the pagoda was seriously exfoliated (2.7 to 5.5%), discolored (39.8 to 58.9), and contaminated with repair materials (3.5 to 9.4%), and bioorganisms (19.3 to 24.4%). Accordingly, conservation treatment was carried out based on preliminary investigation for stable conservation of the pagoda. Overall processes were sequentially proceeded by restoration of the replacement stone, cleaning, joining and consolidation. This study sets up an integrated conservation system from preliminary investigation to conservation treatment of the pagoda. Also, the study will contribute for establishing the future-oriented customized conservation treatment.

Role model has received remarkable attentions in entrepreneurship literature over long time but majority of studies were conducted in western context. As an explorative study, this paper attempted to replicate the effect of role model in eastern context based on the discussions in the literature, using total 440 samples made of Korean and Chinese university students. This study examined the impact and effectiveness of role model on promoting entrepreneurship of university students, considering the main stream of entrepreneurship study has been concentrated on the effect of entrepreneurial education. Our findings presented that role model had a positive impact on both entrepreneurial self-efficacy and entrepreneurial intention of Korean and Chinese university students. Also, entrepreneurial self-efficacy had a significant and positive relationship with entrepreneurial intention of university students. The result of this study implies that role model need to be factored into entrepreneurship education curriculum in order to make it more effective and powerful promotional and educational tool for young university students. Theoretical and practical implications were presented based on the findings of this study.

To learn about the discharge facility management of industrial complexes and the discharge characteristics of water pollutants in drainage, 11 sites were selected, including 16 discharge companies of Hanam Industrial Complex and High-Tech Scientific Industrial Complex and 4 drainages of the industrial complexes. Through the analysis, it was found that 12(75 %) of the 16 discharge companies had specific hazardous substances other than those registered at the time of installation and registration of the wastewater discharge facilities. In terms of other pollutants, 11 of the 16 companies(about 69 %) were found to have pollution items that differed from those included in approved and reported items lists. In addition, Formaldehyde, Mn, Zn, and Ba were discharged from 11 out of the 16 companies. Significantly, one of the specific hazardous water pollutants, Cu, was detected in all discharge facilities at levels from 0.029 to 0.929 mg/L. Even in major complexes drainages and the main stream of the Yeongsangang. As, Dichloromethane, and Chloroform were detected. However, it cannot be conclusively claimed that it is probable that these substances were actually discharged from the above facilities because research was only done in a limited range(Class 1 to Class 3), and therefore, further research is required. In the future, it will be necessary to expand the research scope of the discharge companies in order to establish a database of water pollutants, and to improve permits and reported items based on discharged substances.

Currently, South Korea implements water resources management policies focusing on integrated water quantity, quality and hydro-ecology management. In particular, rehabilitation of natural rivers has become a major issue. As for reservoir operation during non-flood season, efforts have been made continuously to apply the Deficit Supply Method that can maximize water supply to address droughts and increase in water demand. When Deficit Supply Method is applied, the water supply capacity of reservoir can be maximized. However, downstream water flow would remain constant. In consideration that a natural stream, a long-time-created hydro-ecology, can be significantly influenced by flow variability, the Deficit Supply Method-based reservoir operation can generate effective water supply. Still, it may trigger adverse effects from the aspects of natural rehabilitation and hydro-ecology recovery. The main objective of this study is to analyze impacts on downstream flow duration through reservoir simulation by comparing the Firm Supply Method, the Deficit Supply Method and the Selective Deficit Supply Method, and examining each method's effects on reservoir operation. This study found that the Firm Supply Method could maintain water flow variability, but could not maximize water supply capacity. When the Deficit Supply Method was applied, water supply capacity could be increased while remaining vulnerable regarding water flow variability, as a difference between average flow and low flow was negligible at downstream. In comparison, the Selective Deficit Supply Method was found to sustain time-based reliability at 95% or higher, whereas downstream flow duration could be maintained at a level similar to the level generated by the Firm Supply Method.

The purpose of this study is to improve the short term rainfall forecast skill using neural network model that can deal with the non-linear behavior between satellite data and ground observation, and minimize the flood damage. To overcome the geographical limitation of Korean peninsula and get the long forecast lead time of 3 to 6 hour, the developed rainfall forecast model took satellite imageries and wide range AWS data. The architecture of neural network model is a multi-layer neural network which consists of one input layer, one hidden layer, and one output layer. Neural network is trained using a momentum back propagation algorithm. Flood was estimated using rainfall forecasts. We developed a dynamic flood inundation model which is associated with 1-dimensional flood routing model. Therefore the model can forecast flood aspect in a protected lowland by levee failure of river. In the case of multiple levee breaks at main stream and tributaries, the developed flood inundation model can estimate flood level in a river and inundation level and area in a protected lowland simultaneously.

These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

The aims of this study is about distribution characteristics of tidal coastal landforms, and that changing process in the Hampyeung Bay, which has a semi-enclosed bay like basin shape without inflow of stream, the mouth of open sea is narrow and forms with wide ends toward inland sea. The source of deposits are moved materials by tidal currents and from coastal slopes. Main landform elements of study area consist of tidal flat, tidal channels, intertidal sand bar, sea cliffs, and sea terrace. Tidal flats is classified with mud flat and mixed flat by grain size composition. Mud flats have developed at the shoreline area that tidal flat is closed to the continuity of gentle slope, and mixed flat developed at the foot of the sea cliffs and sea terraces. Quaternary deposits were identified in the coastal materials sedimented by the sea-level change. According to the analysis of grain size composition during last ten years, sands and silt has increased 2% and 6% respectively, clay has been decreased by 9%. The concaved tidal flats are colonized by salt plants. Areal changes of salt plants expanded near four times from 2.4km² at the year 2001 to 9.3km² at the year 2009. During the same periods, mean grain size became coarser from 6.5φ to 4.5φ at the salt plants area.

The Four Tenets of Daesoon thought are the Creative conjunction of the virtues of Eum and Yang, the Harmonious union of divine beings and human beings, the Resolution of grievances for the mutual beneficence of all life and the Realization of the Dao in the world. This article compares the concepts of the "Creative conjunction of the virtues of Eum and Yang", the "Harmonious union of divine beings and human beings" and the "Resolution of grievances for the mutual beneficence of all life" with "EumYangDaeDaeRon", "ShinMyonKiDeok", the Theory of Mutual Giving Life / Mutual Destruction (SangSaeng/SangGeukRon) of the Book of Changes and analyzes their common and different points. The conclusion is that Daesoon thought and the philosophy of the Book of Changes share common fundamental standpoints. However, the Daesoon thought defines the world of SeonCheon (the state before the Heaven and Earth have been created) as Mutual Giving Life (SangSaeng), and the world of HuCheon (the state after the Heaven and Earth have been created) as Mutual Destruction (SangGeuk). According to Daesoon thought the Mutual Destruction (SangGeuk) is seen as negative, while according to the philosophy of the Book of Changes the Theory of Mutual Giving Live/Mutual Destruction (SangSaeng/SangGeukRon) is viewed as a positive relationship of EumYangDaeDae. This is a point of difference between the Daesoon thought and the philosophy of the Book of Changes. According to EumYangDaeDae relationship theory the contradictory "other" is viewed not as an enemy, but as a necessary element that assures one's existence. When Buddhism and Christianity first came to existence, they did not belong to a main stream. Later, through continuous theorization and systematization they became generally accepted religions. The case of Confucianism was not much different. During Song dynasty in China Buddhism has contributed to the systematization and establishment of Neo-Confucianism; in the middle of 20th century the Confucian scholars of Hong Kong and Taiwan interpreted and defined Confucianism a new in the light of Western philosophy. Thus the "Modern Neo-Confucianism" came to existence. That's why the history of Confucianism is also called "the history of advancing and developing a concept". From this point of view the critical acceptance of some elements of Confucian, Buddhist, Taoist etc. traditions, as well as modern philosophy, by Daesoon, in order to achieve the systematization of Daesoon thought, is a very important process. As a part of this process, this essay explains the Daesoon thought from the point of view of the Book of Changes, which may be said to present the original East-Asian view of the world. Daesoon's emphasis of human dignity, the equality of sexes, the critics the hierarchical society etc. are rather "modern" and should be examined from the point of view of social science. Besides, leaving the boundaries of "modern philosophy", the concepts of "Harmonious union of divine beings and human beings", viewing the universe as one organism etc. should be approached from the point of view of Post-Modernism.

To determine the cause of the population decline in Gobiobotia naktongensis, substrate preference and burying behaviour were investigated in this study. In general, the species was shown to prefer a substrate size of 1 mm or less, depending on the flow. In addition, the burying depth varied according to the size of the fish and increased with a decrease in water temperature. Our findings showed that the main cause of the population reduction was the physical changes in the substrate structure due to the dams or barrages construction. Notably, the accumulation of silt and mud in the substrate upon the formation of an upstream lentic water region for structural construction and bed armouring caused by scouring and reduced downstream inflow of fine sediment were deterministic in the fish habitat changes, causing problems in burying. As sand substrate structure is critical for the survival and inhabitation of psammophilous species, efficient strategies should be developed with proper habitat management to reduce the anthropogenic damage

This study conducted a research on the position, construction of space and plants of Ten Evergreen's Garden(十靑園) and Oddly Shaped Stone Garden(怪石園) that are central gardens of Eunguhdang(恩居堂) in the poem 'Statement of Responsibility'(Heo Mok, 1595~1682) and Sochi(小痴) Heo Ryeon(許鍊)'s 'Taeyeongsipcheongwondo(漣川台嶺十靑園圖)' in order to bring light on the construction of space and characteristics of them as a garden of the deep pond, Eunguhdang that is a historic site of Misu Heo Mok(許穆, 1595~1682). The characteristics of Eunguhdang, and the meaning of it from the research are expected to be utilized as a basic data for future restoration of it. The results are as follow: In Eunghudang, there are the main building, a detached house, a separated building, and servants' quarters, and the garden consists of Ten Evergreen's Garden between the main building and a Byeolmyo(別廟), a backyard which leads to a green mountaintop, and Oddly Shaped Stone Garden including a pavilion in the front of the detached house. These gardens are thought to have utilized various oddly stones. From the analysis of existing documents such as 'Gwuimonwon(龜文園)' and several interviews, it is concluded that Gwuimunwon might have had Youngdoseo(龍圖墅) that imitated a stream, and Oddly Shaped Stone Garden might have had a garden which imitates Guimonwon standing for graffiti. The evergreen plants in Gwuimonwon correspond to the plants of Sipjangcheong(十長靑) in Youngdoseo, and through these facts, it is thought to have sought "The clean and cool". Furthermore, the diverse colors of flowering trees and flowers in Oddly Shaped Stone Garden and the surrounding of it is symbolizing dragon which is found in Gwuimonwon and that is contrasting with the evergreen plants in Gwuimonwon. The oddly shaped stones in the garden of Eunguhdang have a strange atmosphere which is felt across the whole buildings in Misu, and s a same aesthetic object that are thought to have created beauty of old greenery and antique appearance by utilizing oddly shaped stones. Misu is based on ever green plants seeking change with flowers along with stones that means spirit, body and bones, which is strengthening his intention.
