Unlike other mountains in Korea, Seoul Namsan(南山), which is one of the landmarks that represent the country's capital city, is perceived as a city park. This article aims to study the process that Namsan became a park and the transformation of its place in Korean Emperor and Japanese colonial period. The serial changes in Namsan, in early modern era, mean that is associated with the colonial urbanization and the rule of space by Japan. The stages of Waeseongdae Park(倭城臺公園), Gyeongseong Park(京城公園) and Hanyang Park(漢陽公園) under the leadership of Japan, due to the extension of Japan's power, Namsan has became the park. Here, the park has become a strategic tool of other's occupying Hanseongbu(漢城府), a capital city. The process that Namsan became a park dose not mean making the space for recreation and rest, but is an excuse for using the land. Since then, Namsan's parks barely fulfilled its original function as park as it was transformed into a shrine, Gyeongseong Jinjya(京城神社), for Japanese warriors or was incurred upon by Joseon Singung(朝鮮神宮), which was established as a facility to govern Korea, sometimes is gradually and sometimes is mercilessly. The fact, transplantation of Japanese culture and replacement as ruler space, is another aspect of occupying and govern place. In other words, while the process that Namsan became a park is the way of establishing Japanese force, the transformation of its place show a colonial rule as an aspect of space. Meanwhile, in spite of transformation to shrine, Namsan became accepted as a park for a long time, because of the forest of Namsan. Japan managed forest as a sacred place. It is also a result of the Japanese rule of space.

This research aims to present a methodological approach for repurposing small pockets of national/public lands, which can be constructed as parks, through an investigation of the present status of these areas of national/public lands that are scattered around Busan Megalopolis as well as the suitability of their construction. In order to attain this, this study looked at the present status of these small areas of national/public lands by utilizing a national land, city land list (lot number), land registration map and satellite image of Busan Megalopolis, and evaluating their suitability as parks through GIS analysis and classification. As a result, these small areas of lands with the potential to be turned into parks include 516 spots($375,934m^2$). Geographically, 39% of these areas are located on flat land and are the most scattered. 260 places met the requirements for optimal placement for conversion, while convenience included 305 places, and availability 267 places. The most optimal of the places meeting such standards include 61 spots. The characteristics of these areas of national/public lands include being below $500m^2$, with flatlands and open areas above a 5' grade occupy the highest ratio, accounting for 25.4% of the land studied. These results have offered a methodology for a GIS DB, which can visualize the data for a positive utilization be yond the simple level of the maintenance/preservation of national/public lands and provide basic data for the utilization and management of these types of areas in the future.

Despite the fact that the importance of islands and oceans is increasingly being emphasized as they are recognized as alternative spaces for the future, some islands that have not been designated as cultural assets have lost their natural and cultural landscapes to development projects and other plans for turning islands into tourist resources, and are still in the process of being destroyed. Unlike old perceptions of islands, islands, in the minds of people living in the modern age, have become places for taking a quiet rest or enjoying and appreciating the undamaged beauty of nature itself. Keeping up with the trend of people increasingly visiting the islands these days, it is high time to prepare plans for the promotion, preservation management, and usages of islands based on researches of islands with excellent natural landscapes and through the designation of these islands as cultural properties. As the first step of studying island landscape resources as resources of cultural assets, the current study includes literature reviews and field investigations of Gwanmaedo and Yeongsando, two islands that have been selected as prestigious villages and are part of the Dadohaehaesang National Park. Based on these preliminary investigations, landscape resources showing distinctive natural landscapes and cultural sceneries were selected and analyzed in detail, thus presented for their value as resources of Scenic site and future research.

YoungDo bridge is the first suspension bridge in Busan which experienced several times repair and reinforcement after completion in 1934. The bridge is under demolition for extension and restoration work since 2011. The purpose of this research is to establish data base about modern concrete. The mix design of the concrete is like that cement : fine aggregate : coarse aggregate = 1 : 2 : 4 or 1 : 3 : 6 by the parts. The compressive strength is in the ranges from 50 to 55 MPa and the elastic modulus is in the ranges from 25 to 35 GPa. From the fact that the deviation is less than 10 %, considerably high quality control was conducted in those days. The carbonation depth is 5.92 cm at the bridge post and 14.3 cm at the machine room. That is why ocean environment keeps the high humidity. The diffusion coefficient of chloride ion through the pores in concrete is 1.052e-12 $m^2/s$ from the regression analysis using the experiment data. The water cement ration is estimated at approximately 35 % in case if the concrete using ordinary Portland cement.

This study was performed to evaluate the temporal and spatial variations of the water quality at stream flowing into the Suncheon bay in Suncheon city from October 2008 to August 2009 and to estimate the pollutant sources from the streams using multivariate analysis. Water qualities from Seo stream, Dong stream, Ok stream were evaluated as I grade(very good) that compared to the Water Quality Standard. But Haeryong stream and inlet site of Suncheon Bay in BOD were evaluated as a little bad and fair. Water quality at the stream flowing into the Suncheon Bay was could be explained up to 92.8% by three factors which were included in loading of nutrients, organic matter and total coliform group by the allochthonous matters(53.7%), Topographic Factors(25.0%), seasonal variation(14.2%). The concentrations of total nitrogen and phosphorus at sewage treatment plant and organic matters at Haeryong stream were higher than that of others, respectively. From principal component analysis and factor analysis, it could be suggested that it is very important to make an effort to reduce the nutrients and organic matters from sewage treatment plant and Haeryong stream to be in good conservation of the Suncheon bay.

Old-growth and giant tree is a nonrenewable resource with great value. The purpose of this study is to provide scientific and reasonable evaluations for the preservation and management of the old-growth and giant tree. Until now the research of old-growth and giant tree's value evaluation and authoritative index is so insufficient and imperfection. Combining with the particularity of the old-growth and giant tree, this study analyzed the main value factors of the old-growth and giant tree and objectively selected the evaluation indicators. According to the actual situation value appraisal model of the old-growth and giant tree was builded. The main value factors can be divided into economic value, cultural history, growing place, tree state, tree form, tree vigor, protection level, growth environment, tree species, tree canopy, and so on. The evaluate indicators can be selected and the indicators' weight can be calculate using analytic hierarchy process methods(AHP). Based on economic value and indicators' weight, tree's total value can be revealed. After calculation and analysis, Gyeongju Gyerim Zelkova serrata's value evaluation results is 491,503,300 won. The research results of this study can provide scientific basis and reference to the old-growth and giant trees' value appraisal and loss compensation, and arouse people's environmental awareness.

This is an attempt to reflect on humanity in the post-human era. Here, I think that the question of future human beings should be critically raised in the following two meanings. First, can post-humans recover the body, emotions, nature and women's voices suppressed by modern enlightened subjects? Second, can post-humans preserve humanity by fighting inhumanity without presupposing human essence or immutable foundations? In answer to these questions, I will have a dialogue with M. Heidegger(1889-1976), W. Benjamin(1892-1940), Th. W Adorno(1903-1969). The three philosophers looked at the inhuman world situation brought about by modern subjects and technology, and found the possibility of new human beings. The three philosophers' new human image are the three possible models of post-humanism, 'a human being as ek-sistence' (Heidegger, Chapter 2), 'the man who restored the similarity with the other through innervation' (Benjamin, Chapter 3), 'A human being who negates the inhuman society' (Adorno, Chapter 4), and examines the current status of each. In conclusion, as long as the fourth industrial revolution is developed as a system of digital capitalism that controls the world as a whole from human senses, impulses, and unconsciousness, the necessity of the post-human era is aesthetic authenticity.

Non-traumatic acute myelopathy caused by cervical disc herniation is rare. To date, no case has been reported to be caused by extrusion cervical disc herniation, unrelated to patient posture during surgery. Here, we report the case of a 65-year-old male patient with cervical myelopathy who underwent subsequent arthroscopic rotator cuff surgery under general anesthesia; non-cervical spine surgery. Ed. Notes: I am unable to understand the insertion of the highlighted phrase. Please delete if not required, or revise the sentence appropriately. Patient showed acute postoperative tetraplegia in spite of optimal anesthetic management. He showed no limitation of neck movement at pre-operative airway evaluation, and had no history of trauma to the cervical spine. During surgery, there had been no overextension or twisting of the neck, including at the time of anesthetic induction by tracheal intubation. However, cervical disc herniation causing spinal canal cord compression was detected in the postoperative magnetic resonance imaging, which probably resulted in tetraplegia of the patient. Motor and sensory functions were recovered after 21 days of conservative treatment, including steroid pulse intravenous therapy without any surgical intervention. In this report, the disease is described after reviewing other reported cases; furthermore, we also discuss the pathophysiology of the disease. Based on our report, we propose that under general anesthesia, clinicians should pay attention to the possibility of pre-existing cervical disease, even in non-cervical spine surgeries of geriatric patients.

A total of 10 islands (Kumodo and Komundo in Yeosu City; Oinarodo in Goheung County; Chongsando, Soando, and Pogildo in Wando County; Chodo in Jindo County; Uido, Huksando, and Hongdo in Shinan County) were surveyed to confirm distribution of naturalized plants from June 2006 to December 2008. A total of 100 naturalized plants taxa from 25 families were recorded. The highest number of naturalized plant species (82 taxa) was recorded on Oinarodo, while the lowest number was recorded on Hongdo (42 taxa) and on Uido (34 taxa). A total of 26 naturalized species taxa (such as Dactylis glomerata, Lolium perenne, Bromus unioloides, Rumex obtusifolius, Chenopodium album, Phytolacca americana, Barbarea vulgaris, Lepidium apetalum, Robinia pseudo-acacia, Trifolium repens, Erigeron annuus, Erigeron canadensis, Senecio vulgaris, Xanthium strumarium) was recorded in all study areas. Distribution of naturalized plants were categorized into 7 habitat types based on ecological traits: afforested land, beach, port, and vacant land, road boundary, road cut and slope area, waste arable land, landfill area, and wetland. Systematic management is required to conserve unique landscape, species diversity, vegetation and ecosystem of Dadohae National Park. In order to manage the naturalized plants in Dadohae National Park, basic surveys are most needed to understand distribution and dispersal of naturalized plants communities based on ecological features of each habitat type.

This study was carried out to investigated the effects of soil type and light condition on seedling quality of rare and endemic plants Orostachys iwarenge and Orostachys iwarenge for. magnus. The best seedling quality of O. iwarenge and O. iwarenge for. magnus seedling were shown in Klasmann soil at non-shading or LED (Red+Blue) condition, 50% shading or LED (Red+Blue) condition, respectively. Survival of O. iwarenge seedling was not influenced by the period of experiment but survival of O. iwarenge for. magnus seedling in sandy soil conditions decreased significantly. Results of correlation analysis of seedling quality and survival rate, indicated that O. iwarenge showed a correlation of 0.8 or more at plant height, leaf length and fresh weight. O. iwarenge for. magnus showed a correlation of 0.8 or more at plant height, leaf width and leaf length. Especially, seedling survival of O. iwarenge and O. iwarenge for. magnus showed a correlation of 0.8 or more at first seedling survival and second seedling survival. It was important to manage the early seedling stages of O. iwarenge and O. iwarenge for. magnus. Therefore, seedlings with plant height (over 2.5~4 cm) and root length (over 3~5 cm) were grown vigorously at 35 days after the seedling was transplanted in mid-April in Klasmann soil of 72 plug cell tray at LED (Red+Blue) conditions.
