Using internal transcribed spacer (ITS) sequences and inter-simple sequence repeats (ISSRs) data, genetic diversity of a rare species, Hibiscus hamabo Siebold & Zucc. was examined for 3 populations in Jeju Island, Korea. A total of 14 nucleotide (excluding 3 ambiguous nucleotide) site variation in the ITS was observed from 18 individuals (Population 1, Hadori), which differed up to 13 bp in pair-wise comparison. On the contrary, the ITS sequences of all individuals in Populations 2 and 3 were identical. Genetic diversity estimates including Nei's gene diversity (h) generated by ISSR data were substantially high in Population 1 compared to other two populations. Low genetic variation in Populations 1 and 2 is considered due to genetic drift (bottleneck effect) and limited gene flow in these populations. Considering the differences in genetic diversity, protection of the Population 1(Hadori) is very critical for in situ conservation of Hibiscus hamabo in Korea. If ex situ conservation is required, making the full use of Population 1 will be most efficient.

We systematically analyzed the Wetland Conservation Action Plan of Gyeongsangnam Province to evaluate conservation status in local government level. Project topics were categorized into 1) wetland infrastructure, 2) wetland conservation and wise use, 3) education and awareness, and 4) conservation framework. From 2010 to 2013, 42 projects (145 cases, 88,899 million won) were implemented by 14 affiliated organizations under Gyeongsangnam Provincial Government. The number of projects and budget size has been decreased over 4 years, besides most of main projects were continued. The budgets were largely used for wetland project of cities and counties. Development and implementation of various conservation projects may have considerable potential values in wetland conservation, while it is still difficult to assess their overall effectiveness in the society. Diverse wetland management practices in Gyeongsangnam Provincial Government have accumulated fundamental practices and knowledge for an effective local conservation. These administrative experiences will further benefit other local government to establish wetland management framework. To accelerate policy diffusion to other local governments, Gyeongsangnam Province needs to promote and share leading experiences and information of wetland conservation. Enhanced local government framework by the legislation at central government will further support country-level management plans and practices.
Nowadays most business organizations wish to hire competent people who can do their own jobs efficiently right after their employment. The primary goal of this study is to focus on how we can train undergraduate students in academia-industry collaboration to satisfy this requirement. By making use of the funding from the Ministry of Education & Human Resources Development to support academia-industry collaboration program, we established an intramural company, Hankyong Design Company, and set up several studio courses for junior and senior students. To develop these courses efficiently for the first semester of 2005, studied both intramural and extramural environments of academia-industry collaboration and searched for good examples of them. Based on this investigation, I made some assumptions that how we can perform the academia-industry collaboration program for undergraduate students successfully. I chose several design tasks related to digital communications, and appointed WisePost Inc., an Internet communication service company for MSN Messenger, to be a collaborator. We made the 'Interactive Design' studio courses together and applied the courses to 20 juniors. At the end of the semester, we evaluated the works of the students, and selected and commercialized some excellent items among them. During the course work, I realized the fact that education programs in academia-industry collaboration is feasible for undergraduate students majoring in design. I understanded the overall merits and demerits of conventional studio and academia-industry collaboration courses. In addition, the results from the present study suggest that the role of professor in academia-industry collaboration program would be quite different from conventional studio courses.
Phrygia headgear has an important meaning from the perspectives of costume history and cultural exchanges in ancient times. This study is to investigate the prototype of Phrygia headgear through analysis of its manufacturing methods and styles on the basis of prior studies on ancient sculptures and literatures conducted by European researchers and to examine its history and meanings. In these ways, this study will be helpful in understanding the importance of Phrygia headgear in cultural exchanges between the East and the West. Results of this study can be summarized as follows: Phrygia headgear was orn by eastern tribes, so it was a symbol of those from the east in ancient times. Phrygia headgear is frequently found in Greek artistic works of 5th to 4th century BC that depicted eastern tribes. Also, this headgear can be observed in artistic works for Mithras, Attis, or other gods. Since Phrygia headgear's shape is similar to that of Homer's helm, many researchers believe that it might be originated from Homer's helm. This headgear made of oxen scrotum(stierbeutel) or its surrounding skin has a long end at the top. This long end is round and drooping toward the front side. From such unique shape, we top. This long end is round and drooping toward the front side. From such unique shape, we top. This long end is round and drooping toward the front side. From such unique shape, we can draw a conclusion that Phrygia headgear was made of oxen scrotum and its surrounding skin. Dependingy on drooping patterns, there are various shapes, such as the round, tightly swollen one worn by Mithras, the tongue-shaped one found in Basilika S. Apolinare Nuovo's mosaic depicting three wise men, the balloon-shaped one frequently found in Greek vases depicting Scythian, and the one drooping to the side depicted in Alexandersarkophag. Further, some Phrygia headgear has covers for neck and ears. For example, Phrygia headgear worn by Persian Satrap tribe has such covers attached to the head part. Meanwhile, Phrygia headgear worn by Amazone tribe does not show such separate covers, Rather, one piece of oxen skin was tanned and finished to make such covers. Wearing Phrygia headgear can be interpreted in several ways. Use of animal's skin for wearing things is a unique aspect in ancient societies because they believed that wearing animal skin would give them power of the animal. Further, Phrygia headgear made of oxen scrotum was a symbol of reproductive power to women.
Example-based super resolution(EBSR) is a method to reconstruct high-resolution images by learning patch-wise correspondence between high-resolution and low-resolution images. It can reconstruct a high-resolution from just a single low-resolution image. However, when it is applied to a text image whose font type and size are different from those of training images, it often produces lots of noise. The primary reason is that, in the patch matching step of the reconstruction process, input patches can be inappropriately matched to the high-resolution patches in the patch dictionary. In this paper, we propose a new patch matching method to overcome this problem. Using an image observation model, it preserves the correlation between the input and the output images. Therefore, it effectively suppresses spurious noise caused by inappropriately matched patches. This does not only improve the quality of the output image but also allows the system to use a huge dictionary containing a variety of font types and sizes, which significantly improves the adaptability to variation in font type and size. In experiments, the proposed method outperformed conventional methods in reconstruction of multi-font and multi-size images. Moreover, it improved recognition performance from 88.58% to 93.54%, which confirms the practical effect of the proposed method on recognition performance.
This study focused on changes in form and spatial uses of Urban Hanok in Bukchon, Seoul. There are 10 representative cases which have been renovated through the policy of 'Preservation & Regeneration of Bukchon' by Seoul metropolitan government and other experts. Changes in form and spatial uses of Urban Hanok in Buckon are as follows. First, Changes of scale. Trough removing extension parts, facade of renovated Hanoks are 'transformed' into recovering their identity. Using basements or lofts, intensive application of spaces is transformation which promotes the vitality of Hanoks. Second, changes of space organization. As Hanok changes its function from residence to commercial or cultural use, il a1so changes space character or reorganizes space organization. It is important that deciding function of Hanok has to adjust its scale and organization. Third, changes of construction performance. Through introducing new material and constructing method, performance of wall has been changed respecting its wooden structure and interior-exterior figure. However, technical studies must back it up not to destroy its value of eco-friendly architecture. Fourth, changes of facility systems, like floor heating system. They changes floor level of Hanok equally, and then sections of Hanok have became simple. Furthermore, inserting new facility space, such as boiler room, stand-up kitchen, bathroom and toilet, organization of space also changed. It is necessary that wise alternative proposal through the method of transformation or mutation must be presented. These four changes can be classification into method of 'transformation' and 'mutation'. Changes of scale are method of transformation and changes of space organization are method of mutation. Also, while changes of construction performance are mutation, changes of facility systems are transformation. Recently, as price of lots have been increased, a lot of Hanoks have been commercialized. Thc commercial energy threat 'the identity of Bukchon as residential area'. From now on, to operate 'identity' and 'vitality' complementary, it is necessary to make up for the preservation policy of Hanok and consolidate renovating standards of Hanok which correspond to character of particular region and building usage.
The quality of projector output image is influenced by the surrounding conditions such as the shape and color of screen, and environmental light. Therefore, techniques that ensure desirable image quality, regardless of such surrounding conditions, have been in demand and are being steadily developed. Among the techniques, radiometric compensation is a representative one. In general, radiometric compensation is achieved by measuring the color of the screen and environmental light based on an analysis of camera image of projector output image and then adjusting the color of projector input image in a pixel-wise manner. This process is not time-consuming for small sizes of images but the speed of the process drops linearly with respect to image size. In large sizes of images, therefore, reducing the time required for performing the process becomes a critical problem. Therefore, this paper proposes a fast radiometric compensation method. The method uses color filters for eliminating the color mixing between projector and camera because the speed of radiometric compensation depends mainly on measuring color mixing between projector and camera. By using color filters, there is no need to measure the color mixing. Through experiments, the proposed method improved the compensation speed by 44 percent while maintaining the projector output image quality. This method is expected to be a key technique for widespread use of projectors for large-scale and high-quality display.
For the reasonable use of low grade-shallow geothermal energy by Standing Column Well(SCW) system, the basic requirements are depth-wise increase of earth temperature like $2^{\circ}C$ per every 100m depth, sufficient amount of groundwater production being about 10 to 30% of the design flow rate of GSHP with good water quality and moderate temperature, and non-collapsing of borehole wall during reinjection of circulating water into the SCW. A closed loop type-vertical ground heat exchanger(GHEX) with $100{\sim}150m$ deep can supply geothermal energy of 2 to 3 RT but a SCW with $400{\sim}500m$ deep can provide $30{\sim}40RT$ being equivalent to 10 to 15 numbers of GHEX as well requires smaller space. Being considered as an alternative of vertical GHEX, many numbers of SCW have been widely constructed in whole country without any account for site specific hydrogeologic and geothermal characteristics. When those are designed and constructed under the base of insufficient knowledges of hydrgeothermal properties of the relevant specific site as our current situations, a bad reputation will be created and it will hamper a rational utilization of geothermal energy using SCW in the near future. This paper is prepared for providing a guideline of SCW design comportable to our hydrogeothermal system.
The main premise of this study is that a successful treatment and rehabilitation of the mentally ill depends on an active. coping of their family members, who are the primary care-takers of the patients, even if families are confronting many difficulties because of caring their patients. Accordingly, this study aims to find out which factors are related to families active coping with the mentally ill. This study is conducted the survey with 191 family members of the mentally ills in order to discover: 1) what kinds of relations do exist between sociodemographic factors of the respondents, care-burden toward the mentally ill, and social supports, and the active coping, and 2) in what extent do these related factors affect on the active coping. The major findings of the study are: 1) gender and educational background of the respondents are positively related to the active coping; 2) regarding care-burden felt by the respondents, there is statistically significant positive relationship between - the respondents' burden due to a lack of social and institutional support and their active coping; 3) considering the relationship with social support, there is highly positive relationship between decision. emotional. material supports and the active coping; 4) using a multiple regression, respondents' sociodemographic background, care-burden, social support affect significantly on the active coping by 26.2% of explanatory power; and 5) using a step-wise multiple regression, the most powerful influenced factors on active coping are emotional support, burden due to a lack of social and institutional support, and educational background of the respondents. In conclusion, this study recommends clinicians to use an educational and support model for the families. All these efforts will contribute to enhance active coping of the families with the mentally ill.

In this study, the efficiency of two-dimensional inundation analysis using road network was demonstrated in order to reduce the simulation time of numerical model in urban area. For this objective, three simulation conditions were set up: Case 1 considered only inundation within road zone, while Case 2 and 3 considered inundation within road and building zone together. Accordingly, Case 1 used grids generated based on road network, while Case 2 and 3 used uniform and non-uniform grids for whole study area, respectively. Three simulation conditions were applied to Samsung drainage where flood damage occurred due to storm event on Sep. 21, 2010. The efficiency of suggested method in this study was verified by comparison the accuracy and simulation time of Case 1 and those of Case 2 and 3. The results presented that the simulation time was fast in the order of Case 1, 2 and 3, and the fit of inundation area between each case was more than 85% within road zone. Additionally, inundation area of building zone estimated from inundation rating index gave a similar agreement under each case. As a result, it is helpful for study on real-time inundation forecast warning to use a proposed method based on road network and inundation rating index for building zone.
