  • Purpose: In this report we are going to discuss about the functional evaluation and the outcome of treatment of metastatic tumor in the lower extremities treated with tumor prosthetic arthroplasty. Materials and Methods: This report is based on nine patients diagnosed as a metastatic tumor and treated by tumor prosthetic arthroplasty, from June 1998 to December 2001. Age of the patients ranged from 49 to 63 with the average of 56.3. The average follow up period was 23.4 months. Two patients had lung cancer, three had breast cancer, two had renal cancer, one colon cancer, and one had multiple myeloma. All these were primary cancers. The site of metastasis were six in proximal femur, two in distal femur, and one in proximal tibia. Tumor excision was performed after biopsy in following the principle of primary tumor management. Excision with wide surgical margin was tried as possible could. Six cases were treated with tumor prosthesis, and the other three cases were reconstructed with bone cement and arthroplasty. Results: The functional evaluation in the extremities at the last follow up was performed on Enneking evaluation score with 6 categories. The highest scored 26, and the lowest scored 10, with an average of 19.5. A case in which the patient died 15 days after the operation was excluded from the evaluation. Among the categories, emotional acceptance to postoperative function and pain relief were highly scored. At the final follow up, seven patients survived, and one colon cancer patient died 68 days after operation. Conclusion: Metastatic tumor occurring in joints of lower extremities could be treated in accordance to the treatment principle of primary tumor. By insertion of tumor prosthesis, we can get satisfactory results of function in the lower extremity and pain relief especially. So, this aspect of medical favor must be considered in treating patients.

  • The purpose of this study was to improve upon school health by understanding the present status of school health and escpecially to investigate the performance rate of regular health instruction. 261 schools, including middle and high schools enrolled in the Busan Educational Association, were sent Questionnaires. Data was collected from the 25th of January to the 10th of April, 1994. 229 subjects who responded to the Questionnaires were finally analyzed as samples. Among them, 127 were school nurses and 102 were teachers acting in a school health capacity. The results of this study are summerized as follows: Of the teachers holding additional school health responsibilities, $85.6\%$ worked in private schools. Many of them $(74.5\%)$ were formally dissatisfied with their ability to provide care because $85.3\%$ of them had never studied any school health. Some of them$(30.4\%)$ didn't know about the annual school nursing budget and $23.5\%$ of them hadn't taught any health education to students. In spite of this fact, they were placed in charge of a school health activity against their own will. There were statistically significant differences in the performance of school health affairs between nurses and teachers holding additional school health (p<0.001) as follows: annual school nursing budget, Health Program Planning and Evaluation, annual purchase price for medicines, average students cared for per day, average students who held at least one consultation per month and extra. Surely, the self-confidence of school nurses was higher than that of teachers with school health as an assigned responsibility. This was demonstrated by a significant statistical difference (p<0.01) in the responses by the two groups. $88.2\%$ of the school nurses and $73.5\%$ of teachers for school health thought that regular health instruction was necessary. But regular health education had been performed only by $32.8\%$ of respondents. Among them, 84% were school nurses and $16\%$ were teachers holding additional school health. Of the persons who performed regular health education, $69.3\%$ used less than $60\%$ of the health content of the athletic textbook. And $64\%$ of them said teaching materials were insufficient. Most of them $(69.4\%)$used home made lesson plans. which they compiled from various sources. There was a significant difference in the formality of the health lesson according to the concern of the school principal (p<0.01) and there was a significant difference in performing health education between school nurses and teachers holding additional school health (p<0.001) It appears that there are a lot of problems with providing school health care using people who are untrained. In a word, school health nurses with professional training are needed in order to perform the qualitative management for the health of the students. These days, regular health education is an indispensable part in making students improve their self-care abilities. Therefore a more effective and better defined program should be prepared for regular systematic health education. To resolve these problems, present laws and regulations related to school health should be revised considering the specialist's request for the improvement of school health. In addition, the concern and financial support of the government are essential.

  • The Biotope Area Ratio (BAR) is a quantitative pre-planning index for sustainable development and an integrated indicator for the balanced development of buildings and outdoor spaces. However, it has been pointed out that there are problems in operations management: errors in area calculation, insufficiency in the underground soil condition and depth, reduction in biotope area after construction, and functional failure as a pre-planning index. To address these problems, this study proposes implementing LIM. Since the weights of the BAR are mainly decided by the underground soil condition and depth with land cover types, the study focused on the terrain and pavements. The model should conform to BIM guidelines and standards provided by government agencies and professional organizations. Thus, the scope and Level Of Detail (LOD) of the model were defined, and the method to build a model with BIM software was developed. An apartment complex on sloping ground was selected as a case study, a 3D terrain modeled, paving libraries created with property information on the BAR, and a LIM model completed for the site. Then the BAR was calculated and construction documents were created with the BAR table and pavement details. As results of the study, it was found that the application of the criteria on the BAR and calculation became accurate, and the efficiency of design tasks was improved by LIM. It also enabled the performance of evidence-based design on the terrain and underground structures. To adopt LIM, it is necessary to create and distribute LIM library manuals or templates, and build library content that comply with KBIMS standards. The government policy must also have practitioners submit BIM models in the certification system. Since it is expected that the criteria on planting types in the BAR will be expanded, further research is needed to build and utilize the information model for planting materials.

  • There are two types of nuclear reactors in Korea and they are PWR type and CANDU type. The safe management of the spent fuels from these reactors is very important factor to maintain the sustainable energy supply with nuclear power plant. In Korea, a reference disposal system for the spent fuels has been developed through a study on the direct disposal of the PWR and CANDU spent fuel. Recently, the research on the demonstration and the efficiency analyses of the disposal system has been performed to make the disposal system safer and more economic. PWR spent fuels which include a lot of reusable material can be considered being recycled and a study on the disposal of HLW from this recycling process is being performed. CANDU spent fuels are considered being disposed of directly in deep geological formation, since they have little reusable material. In this study, based on the Korean Reference spent fuel disposal System (KRS) which was to dispose of both PWR type and CANDU type, the more effective CANDU spent fuel disposal systems were developed. To do this, the disposal canister for CANDU spent fuels was modified to hold the storage basket for 60 bundles which is used in nuclear power plant. With these modified disposal canister concepts, the disposal concepts to meet the thermal requirement that the temperature of the buffer materials should not be over $100^{\circ}C$ were developed. These disposal concepts were reviewed and analyzed in terms of disposal effective factors which were thermal effectiveness, U-density, disposal area, excavation volume, material volume etc. and the most effective concept was proposed. The results of this study will be used in the development of various wastes disposal system together with the HLW wastes from the PWR spent fuel recycling process.

  • This study is mainly based on the introduction process of formative art education method of Korean Bauhaus which was brought in this CQuntry through Japan. The introduction routes into Korea of Bauhaus education method by way of the United States through Germany have been disclosed since 1945, including Korean students studying in the United States as well as Scandinavian countries. Those introduction of Bauhaus method by Korean students into Korea had influenced the domestic university education. However, it was worth notice that Park Hui-rak pointed out through his writing that Bauhaus education method had already existed in the CQuntry before 1945 when korea was liberated from 35 years of Japanese colonial rule. Park hinted in his book of "Korean Design History,199B" that the curriculum of primary school, then affiliated with Taegu Education College had been possibly influenced from Composition Education" idealogy led by Japanese Kawakita Rensichiro. In Japan, Bauhaus education method had been independently introduced by civilians like primary school teachers of Kawakita. However, the possible introduction of the informative art education in the country by way of Japan leaves a lot of things to be considered. Because, the introduction was carried out by Choson governor-General which took charge of colonial rule of korea. Accordingly, the purpose of this study is to make full explanation on the introduction of formative art education and on the types. For that purpose, examinations on various materials and information released by many educational institutes as well as by choson Governor-General were included. As the result, it was possible to find out a trace of "Composition Education : Japanese Bauhaus Formative Art Education" in 1937, one year earlier pointed out. And it was remarkable that two interested books were found out, which mainly dealt with Spanung of Composition and Dynamic sense. Finally, through examinations in many aspects, five drawing education books written in 1930s, such as Drawing Guide Details and indication, were proved to be equal to Bauhaus Composition Education in terms of terminology and contents. Moreover, it has been made clear that Composition education Choson was made mostly under the control and management of Choson Governor-General in the of books on education systems in then education college.

  • The environmental impacts of 95% remediation of a total petroleum hydrocarbon-contaminated soil were evaluated using life cycle assessment (LCA). LCA of two remediation systems, soil vapor extraction (SVE) and biopile, were conducted by using imput materials and energy listed in a remedial system standardization report. Life cycle impact assessment (LCIA) results showed that the environmental impacts of SVE were all higher than those of biopile. Prominent four environmental impacts, human toxicity via soil, aquatic ecotoxicity, human toxicity via surface water and human toxicity via air, were apparently found from the LCIA results of the both remedial systems. Human toxicity via soil was the prominent impact of SVE, while aquatic ecotoxicity was the prominent impact of biopile. This study also showed that the operation stage and the activated carbon replacement stage contributed 60% and 36% of the environmental impacts of SVE system, respectively. The major input affecting the environmental impact of SVE was electricity. The operation stage of biopile resulted in the highest contribution to the entire environmental impact. The key input affecting the environmental impact of biopile was also electricity. This study suggested that electricity reduction strategies would be tried in the contaminated-soil remediation sites for archieving less environmental impacts. Remediation of contaminated soil normally takes long time and thus requires a great deal of material and energy. More extensive life cycle researches on remedial systems are required to meet recent national challenges toward carbon dioxide reduction and green growth. Furthermore, systematic information on electricity use of remedial systems should be collected for the reliable assessment of environmental impacts and carbon dioxide emissions during soil remediation.

  • This research was performed to evaluate the recycling feasibility as a construction material of dredged harbor soil mixed with clay and glass frit. Concentration of heavy metals of the dredged soil from D harbor was severly high, showing Zn of 526.0~13,150.1 mg/kg. The dredged soil was maily composed of 48.30 wt% $SiO_2$, 16.60 wt% $Al_2O_3$, 10.10 wt% CaO, 7.75 wt% $Fe_2O_3$. The clay and the glass frit contained 70.82 wt% $SiO_2$ and $Al_2O_3$ 18.78 wt%, and 71.75 wt% $SiO_2$, 13.99 wt% CaO, 8.51 wt% $Na_2O$, respectively. After adding 10~40 wt% to the clay and sintering them at $1,000^{\circ}C$ or $1,100^{\circ}C$, the compressive strength of the sintered specimens showed $132.6{\sim}178.5kgf/cm^2$ or $581.2{\sim}793.7kgf/cm^2$, respectively. In case of SC46 with the addition 40 wt% of the dredged soil to the clay, the compressive strength ($793.7kgf/cm^2$) of specimen sintered at $1,100^{\circ}C$ was over 5 times higher than that at $1,000^{\circ}C$. The specimen mixed with 40 wt% of dredged soil, 60 wt% of clay and 1 wt% of glass frit satisfied the 1st grade standard for clay brick by KS L 4201. The results of all specimens by Korean Standard Leaching Test also satisfied the standard criteria.
