This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

This report is to introduce detail processes during the restoration/revision project for the Korean Standard Methods for Marine Environment. The processes are composed of 3 steps: questionaries, QA/QC confirming step by CRM(Certified Reference Materials), and advisory council by specialists. The questionaries required four main topics to be included to the restoration/revision protocol: 1. the guidelines to sampling, transportation, storage, and pre-analytical procedures for the marine specimens, 2. the unified analytical method, especially for the organic compounds, 3. the QA/QC test requirement for CRM, 4. introduction of diverse analytical instruments, 5. the customer- friendly express of the protocol. Based on these new protocol, we expect two most important effects: 1, increased insurance of international credibility and equivalence by the QA/QC procedures, 2. increased conformability and representatively from wide-spread use of the protocol. Finally we suggested several residual topics remained to the inter-government cooperation.

Background Perineal defects are commonly encountered during the treatment of conditions such as malignancy, infectious disease, and trauma. Covering large defects in the perineal area is challenging due to its complicated anatomy and the need for functional preservation. Methods Fourteen patients who underwent reconstructive surgery with multiple perforator flaps for defects >$100cm^2$ in the perineal area were included in this retrospective cohort study. Characteristics of the perforator flap operation and postoperative outcomes were reviewed. Results Reconstruction was performed using 2 perforator flaps for 13 patients and 3 perforator flaps for 1 patient. Internal pudendal artery perforator flaps were mainly used for covering the defects. The average defect size was $176.3{\pm}61.8cm^2$ and the average size of each flap was $95.7{\pm}31.9cm^2$. Six patients had minor complications, such as wound dehiscence and partial necrosis of the flap margin, which were corrected with simple revision procedures. Conclusions Multiple perforator flaps can be used to achieve successful reconstructions of large perineal defects that are difficult to reconstruct with other coverage methods.

Cultural assets restoration is being considered highly as a practical way to extend the lifespan of damaged cultural assets and re-highlight their value. However, restoration process has been mostly dependent on the manual work involving the experience and skill of a person performing restoration, thereby requiring much time and effort. In recent, it became possible to apply a method allowing restoration to be performed more accurately and easily according to the material characteristics and shape of cultural assets. Namely, it is to use a method of printing out the 3D shape data computed in computer as real object by using 3D printer for the restoration that has been performed manually. The missing part of a cultural asset is computed into computer data first and is printed out by using 3D printer to undergo a simple shaping process. The result of 3D printer application showed that repetitive output and shape and figure revision of digital data were possible, and it was possible to improve the degree of completedness of restoration through test output using various types of restoration materials using various materials. For the purpose of verifying the possibility of applying 3D printer to restore missing part of earthenware, two pieces of modern reproductions, namely, the Seven Treasure Incense Burner and Earthenware with Wagon Wheel Decoration, were artificially damaged. The restoration result showed that compared to manual work, it showed better effectiveness in curtailing work time and reproducing accurate shape. On the other hand, secondary manual work was slightly needed for detailed binding and to vividly express surface texture.

Demands for housing has diversified recently due to low birth rate and the growth of aging population. Also, a share of idle houses and obsolete houses over 20 years old is gradually rising. Therefore, there is a need for a sustainable, environment-friendly improvement policy that is in line with a new housing paradigm and avoids full-scale new construction, such as a customized housing renovation plan considering local economic circumstances. Therefore, afforestation system applicable to buildings are assessed positively, but lack objective performance evaluation. Through one-year, long-term monitoring of replicated obsolete buildings that have poor insulation performance, this study calculated monthly average power consumption and analyzed power charges by applying pricing plans before and after the revision of progressive tax in order to examine economic effects expected by applying the afforestation system. In the obsolete buildings, the study showed that monthly average power consumption was reduced by 16.6kWh with 5.2% average reduction rate. Highest reduction was made in July at 11.3%. Aggregate monthly power consumption charges were relatively high in winter before and after the revision of progressive tax. Power charges reduction effect was highest in March when monthly power consumption was reduced to 300kWh level by applying the afforestation system.

Purpose: To correct the facial asymmetry and to achieve symmetry and balance, not only the soft tissue restoration of deficits but also creation and facial contour line such as mandible border and angle is important. Micro fat graft has limitation such as high resorption rate and somewhat limited ability to emphasize the rigid bony characteristics of the mandible angle due to its innate soft consistency. We have investigated the advantages of dermal fat graft over micro fat graft to correct asymmetry of the lower face in patients who had undergone mandibular reconstruction or distraction, using comparative analysis. Methods: Total of 12 patients were enrolled in our study: 6 micro fat graft and 6 dermal fat graft. Postoperative results were compared and analyzed at immediate postoperative period and more than 1 year later in each group with photographs, and analysised with image J program. Result: No complications were noted both in the micro fat type and the dermal fat type of procedures such as fat necrosis or micro calcifications. All of the patients who received micro fat graft, however had considerable amount of fat resorption after the procedure which led to two additional fat graft procedures. Although minor contour obliteration due to contracture was seen in patients who had undergone dermal fat graft procedure, no definite resorption was found even after more than one year follow-up. Results of dermal fat graft patients were satisfactory in terms of mandible angle symmetry. Secondary revision was necessary in one case due to overcorrection using dermal fat graft. Conclusion: The dermal fat graft has many advantages over the conventionally more popular micro fat graft to correct asymmetry of the lower face following mandible reconstruction owing to its lower resoption rate, more effective in emphasizing the natural curvilinear anatomical contours of the mandible angle and body and lower complication rates such as fat necrosis or micro calcifications.

With the increase in occurrence frequency and severity of natural disasters due to climate changes arising from global warming, damage in the landscaping field is rising. This leads to legal disputes, and is increasing social and economic damage, too. Especially even though landscape trees which are highly affected by external environments, suffer lots of damage from natural disasters, there is no specific scope of disaster criteria and thus it brings plenty of problems of damage restoration and compensation. Therefore, this study aims to suggest that gives ways to improve related criteria for damage of landscape trees from natural disasters. For this objective, this study analyzed damage cases of landscape trees and precedents, and compared Korean and Japanese legal systems and criteria regarding natural disasters with each other. The analysis result showed that opinions of experts have a great deal of influence on judgment results, since there is no definite legal basis on damage from natural disasters in the landscaping field. This implies the need for a professional and objective appraisal process. According to the comparative analysis of Korean and Japanese legal systems and criteria regarding natural disasters, Korea lacked in laws and criteria on natural disasters of landscape plants in Korea, whereas there were concrete disaster assessment standards of landscape trees in Japan. For improving natural disaster-related systems and criteria in the landscaping field, therefore, this study presented 'Revision of related laws', 'Revision of appraisal and loss assessment criteria', 'Revision of standard specification of landscaping project', 'Compulsory insuring against disasters', 'Reasonable fulfillment of contract', and 'Compulsory cost estimation for disaster restoration', as improvement plans.

The purposes of this study are to revise an site-based environmental education(EE) Program evaluation chart and to evaluate site-based EE programs using the chart. For revising the evaluation chart, several elements in the former chart were changed, infused, deleted, integrated, or split. The points of some elements in the former chart were also changed. The revised chart consist of 38 elements in 6 areas: purpose and goal, teaching and learning plan, teaching and learning process, educational effect and programs evaluation, Program characteristic, and program operation. Using the revised chart, the researchers evaluated 159 site-based EE programs, funded by the Korean Ministry of Environment in 2002. The result indicated that the mark of 'teaching and learning plan' area is higher than other areas, while the mark of 'educational effect and programs evaluation' is the lowest. On the basis of evaluation, the researchers offered some recommendations for the Korean site-based EE programs.

Background: The conventional surgical method for reconstructing orbital floor fractures involves restoration of orbital continuity by covering an onlay with a thin material under the periorbital region. However, in large orbital floor fractures, the implant after inserting is often dislocated, leading to malposition. This study aimed to propose a novel implanting method and compare it with existing methods. Methods: Among patients who underwent surgery for large orbital floor fractures, 24 who underwent the conventional onlay implanting method were compared with 21 who underwent the novel ${\gamma}$ implanting method that two implant sheets were stacked and bent to resemble the shape of the Greek alphabet ${\gamma}$. When inserting a ${\gamma}$-shaped implant, the posterior ledge of the orbital floor was placed between the two sheets and the bottom sheet was impacted onto the posterior wall of the maxilla to play a fixative role while the top sheet was placed above the residual orbital floor to support orbital contents. Wilcoxon signed-rank test and Mann-Whitney U test were used for data analyses. Results: Compared to the conventional onlay method, the gamma method resulted in better restoration of orbital contents, better improvement of enophthalmos, and fewer revision surgeries. Conclusion: Achieving good surgical outcomes for extended orbital floor fractures is known to be difficult. However, better surgical outcomes could be obtained by using the novel implantation method of impacting a ${\gamma}$-shaped porous polyethylene posteriorly.

The restoration effects in two sorts of forests created and managed on the bases of ecological principles in Sihwa industrial complex and Mt. Surak respectively were evaluated in both viewpoints of species composition and diversity. Species composition of the forests created based on the ecological design was move similar to that of the natural forests compared wit h the forests constructed by applying the landscape architectural method. The increased species diversity in the ecologically created forest reflected the effect as well. Black locust plantation managed by applying the ecological principle showed move similar species composition to the surrounding natural forest than the forest left without any management. Furthermore, the former forest showed higher species diversity than the latter one. The methods, which create and manage a forest based on ecological principles, revealed several problems, such as lack of specialty of project operators and inspecting officers, construction regulations without the ecological background, absence of the endemic young trees to be introduced in diverse natural environment, etc. Preparation of guidance for ecological planting and systematic environmental education including revision of construction regulation were recommended as the measures to solve such problems.
