Park planning is done in a way to satisfy various expectations, including providing green space and offering urban space with specific and detailed strategies. This study focuses on large-scale parks that have been built since 2000 or that are going to be built. Their significance in the city was analyzed along with strategic characteristics for designing urban parks, and implications are suggested. First, the design aspects of urban parks have gradually tended towards flexibility for adapting to the diverse surrounding environments. Relating the parks to the surrounding area is realized through connection with facilities or planning to process the border area smoothly. Second, unlike in the past, urban parks are not just simply used as a resting space but play other productive and complex roles in the urban space for healing in the community. Third, six design strategies are being applied in these parks through mutually complex relations. Relations with external parties and planning inside the parks add more importance to the park for the community. Fourth, the changes of vertical time are reflected in park planning strategies and tend to form a floor plan. This is associated with growing park planning and is being realized as a major characteristic in urban park planning strategies.

Purpose: Lipofibromatous Hamartoma(LFH) of nerve is a tumor - like lipomatous process principally involving the young persons. This is rare disease characterized by a soft slowly growing mass surrounding and infiltrating major nerves and their branches of the palm and digits. LFH of nerve usually affects the median nerve, with the most common sites of presentation being the distal forearm and hand in the wrist or palm. It may cause symptoms of compression neuropathy and is associated with macrodactyly. Recently, MRI plays a major role in confirming the diagnosis of LFH. Therefore, we present two cases of LFH in the hand with MRI features and surgical management. Methods: One is 6 - years - old female who presented with macrodactyly involving both the soft tissue and bony parts of the second, third and forth digits of her right hand. The other one is 16 - years - old man who presented involving the soft tissue of the second and third digits of his right hand, with pain and numbness, along with motor and sensory deficits in the median nerve distribution. To evaluation about LFH, we enforced preoperative MRI and physical examination. After confirming the diagnosis of LFH, we proposed decompression of all compromised peripheral nerve to help alleviate pain and paresthesia to reduce the likelihood of permanent motor and sensory sequelae. Results: A characteristic feature on MRI is the appearance of serpentiform nerve fascicle surrounded by fibro - fatty tissue within the expended nerve sheet. Distribution of fat between fascicles is asymmetric. Two cases were treated by limited debulking of the redundant tumor tissue and excision of epineurial fatty tissue. These cases were performed with relief of symptom. Conclusion: MRI not only confirms the diagnosis, it also provides a detailed assessment of nerve involvement preoperatively. Especially, on coronal images, the nerve has a spagetti - like appearance that is pathognomonic of LFH. Recommendations for early treatment include decompression of the carpal tunnel, debulking of the fibro - fatty sheath, microsurgical dissection of the neural elements and excision of involve nerve with or without grafting.

Recently, the cultivated area is reduced, the ratio of upland-field in the total cultivated area is increasing relative appeared in 36.2% in 1990 from 43.7% in 2013. If upland-field can be applied well designed-infrastructure, good income crop production is possible, however, maintenance of infrastructure and a significant portion of the upland-field is maintained under insufficient infrastructure. While imports of agricultural products expanded since the 2000s in progress, looking at the self-sufficiency of upland-field crops, it is reduced to from 90% to 42% for the pepper, it is from 90% to 74% for the garlic, cereals is reduced from 42% by 26%. As a result of these conditions, the competitiveness of farmers has weakened, the risk to meet the challenges of this area of production and supply reduction increased. This study was the first to conduct a basic evaluation index, data analysis and evaluation of indicators to diagnose the agricultural production capacity of the upland field. 12 kinds classified index of producing conditions from the natural environment and eight factors for the cultivation and production capabilities have developed for the assessment of productivity of upland-field (especially Kimchi cabbage). Through this regional imbalance was found, based on the production capabilities conditions are good in Haenam, Gangneung, Pyeongchang. 3 Regions have been low and the lowest Youngwol to 0.8992. Climate(Cultivation conditions) indicators of Mungyeong region is the highest, relatively low areas were in Taebaek. In particular, it is determined to be preferred that the area required for the enhancing the production environment based on providing the convenience for the producing and maintenance of the first production area. It is necessary Increasing part of mechanization, agro-industrial competitiveness through aggressive management plans for facilities as required in the process of post-harvest storage, processing, distribution line can be improved.

World security market has continuously been growing since the 2000s. The growth rate seems to reach up to 7-8% annually. What is more, Korea is expected to be one of the most rapidly developing markets, Based of this view, this research investigates the principal drivers to have affected on the expansion of Korean security market over the past 20 years. In addition to that, this study also examines the influence of recent changes in the world economy and globalization, socio-demographic change, development of information technology on the future security market. The data reviewed in this study are official crime rates, socio-economic indicators, statistics from the National Police Agency and the business reports of a leading private security company. This study shows that several factors such as rising crime rates, lack of police capacities, national economic growth and rising household income have played important roles in development of Korean market. It is also expected to keep those positive affects on the future market. On the other side, in recent years, the security market seems to be increasingly affected by new social economic changes. Those are impact of last aging society, rapid increase of individual household and women's participation in labor market. These factors seem to increase personal and household needs for security service. World economy, globalization process and development of information technology are also deemed to give rise to social demands for surveillance, monitoring service and security in cyber space.

In comparison with other terrestrial ecosystems, rice paddies are unique because they provide the primary food source for over 50% of the world's population, and act as major sources of global methane. The present paper summerizes a long-term field study that combine carbon isotopes, and canopy-scale flux measurements in an irrigated rice paddy, in conjugation with continuous monitoring of environmental, and vegetational factors. Both $CO_2$, and methane fluxes were largely influenced by soil temperature, and moisture conditions, especially across drainage events. Soil-entrapped $CO_2$, and methane showed a gradually increasing trend throughout growing season, but rapidly decreased upon flood water drainage. These variations in flux were well correlated with changes in concentration, and isotope ratio of soil $CO_2$, and methane, and of atmospheric $CO_2$, and methane within, and above the canopy. The isotopic signature of the gas exchange process varied markedly in response to change in contribution of soil respiration, belowground storage, fraction of $CO_2$ recycled, magnitude, and direction of $CO_2$ exchange, transport mechanism, and fraction of methane oxidized. Our results clearly demonstrate that stable isotope analysis can be a useful tool to study underlying mechanisms of gas exchange processes under natural conditions.

The present times is rapidly growing and changing. As both an industry and a social legislation are running after a generality, relatively the number of people who are out of it is gradually increasing. Those people are getting skeptical about their positions as well as their existences, so that a social deviant phenomenon has been continuously arising by themselves in public and private area. It is the Vandalism . People are often exposed to this Vandalism which is occurring around their life. Accordingly this study analyzed cause-and-effect Vandalism. As a means of impediment against the progressing Vandalism in design process, the study as been developed by approaching to an ergonomics design, a simple shape design (minimalism), a semantic design, a re-useful design. As a result, it comes to the fact that the Vandalism from the view of design is caused by a lack of ergonomics and user-interface, a failure of simple structure, a complication of excessive functions. Furthermore, it comes to the conclusion that industrial design is playing an important role in the contribution of social development, to create a design obstructing the vandalism will bring development of sound society.

Mobile e-business is in wide use with the rapid growth of wireless internet users. To meet the growing requests for mobile e-business the productivity of mobile applications has been demanded. The WAPSiteGen, introduced in this paper, automatically generates a 3-tier WAP application that needs a new application database or that already has an application database to increase the productivity. The WAPSiteGen generates the EJB components that handle business logic and the JSP Web components that process user-made queries and the WAP Push feature. For a presentation layer, it also generates the HTML forms for an application manager and the WML decks for end users, which consists of many cards. The WAPSiteGen enhances extendibility, reusability and portability of generated 3-tier applications by comprising such component technologies as EJB and JSP. Furthermore, it supports the WAP Push services for generated applications that provide necessary information to wherever and at whenever a user wants. Since the applications generated by the WAPSiteGen provide the information on an interested entity as well as the information on all the directly or indirectly related entities to the interested one, it shows faster information accessibility. In this paper, we explain the functionality and implementation of the WAPSiteGen and then show its merits by comparing the WAPSiteGen to commercial WAP application generators.

Throughout developing digital technology, reproduction of image is growing better day by day. And at the same time, diverse image editing softwares are developed to manage images easily. In the process of editing images, those programs could delete or modify EXIF files which have the original image information; therefore images without the origin source are widely spread on the web site after editing. This matter could affect analysis of images due to the distortion of originality. Especially in the court of law, the source of evidence should be expressed clearly; therefore digital image EXIF file without deletion or distortion could not be the objective evidence. In this research, we try to trace the identification of a digital camera in order to solve digital images originality, and also we focus on lens distortion correction algorism which is used in digital image processing. Lens distortion correction uses mapping algorism, and at this moment it also uses interpolation algorism to prevent aliasing artifact and reconstruction artifact. At this point interpolation shows the similar mapping pattern; therefore we want to find out the interpolation evidence. We propose a minimum filter algorism in order to detect interpolation pattern and adjust the same minimum filter coefficient in two areas; one has interpolation and the second has no interpolation. Throughout DFT, we confirm frequency character between each area. Based on this result, we make the final detection map by using differences between two areas. In other words, thereby the area which has the interpolation caused by mapping is adjusted using minimum filter for detection algorism; the second area which has no interpolation tends to different frequency character.

This research pertains to the interpretation of the many characteristics of the growing process of Library and Information Science in Korea with respect to its connection with discussion of the system of discipline. The result of the research are as follows. The Library and Information Science in Korea has gone through three distinct stages. The first stage spans the period from the late 50s to the 1960s during which three was an attempt to establish a relatively independent system of scholarship of Library and Information Science, although it was still heavily reliant on scholarship from Japan and the United States. The main characteristics of this first period is, firstly, that there a n.0, ppeared, for the first time, an awareness of a need to escape the attitude of foreign-orientation and to develop our own scholarship. Secondly, an effort was made to constitute the scholarship as a science (social science). Thirdly, there began a faint effort to import and a n.0, pply Information Science. The second stage covers the period between the 70s and the 80s, and saw the induction of Information Science begin in earnest and become the subject of education and research. The period was also marked by exploration of an alternative term to "Library Science", which was at the time being used. In addition, the period was a time of confusion for the examination of scholarship due to the induction of the new field of Information Science to what had already been a fragile structure of scholarship. This phenomenon served to intensify the doubts which had surfaced about existing term of Library Science, and ultimately played a large role in the a n.0, ppearance of the new term of Library and Information Science. Of course, there were a number of reasons which had made the change of term difficult, but it and be seen that the term change began in earnest after the change was adopted in the names of the university departments associated with the field in the late 80s. The third stage covers the period after the begining of the 90s. This stage saw the prominence of criticism and self-examination of the existing distorted foundational structure of Library and Information Sciences in Korea at the time, and, at the same time, a new methodology or research paradigms were advocated. It was a presenation of a new way of achieving a "Korean Library and Information Science" in order to understand and overcome not only the problems within the Korean libraries, but also within Library and Information Science in Korea. This caused repercussions to be felt not only among academics, but also among those actually working within the library systems. It moved academics toward a more practical scholarship, it inspired the prominence of a new scholarly methodology called a reform in academic writing, and even influenced specific research activities.research activities.
