Korean society has begun to transition toward a multicultural society, and the rate of change is increasing. If so, is our society ready to meet this change of society? It is true that Korean society has been dominated by the paradigm of 'monoethnicity', and traditionally has been regarded as a virtue to maintain this view. However, it is worth noting that isolated single cultures have historically met a disastrous end. On the contrary, people who have adapted their culture and style have enjoyed prosperity. Korean society has hovered between embracing and rejecting the flow of change, and has finally accepted them to choose the way to go on a multicultural society living together. However, it seems that the changes in policy have not kept pace with recent changes in society. Despite the fact that the most efficient way to change perception is to establish and implement appropriate educational policies promoting multiculturalism, most education in Korean society has focused on the closed form of education, for the influx people, not having been made proper education for most of Korean people who should actually accept them and get along with them. Therefore, they have been striving for an assimilated viewpoint that simply get it transformed into Koreanized, not understanding and accepting them as they are. However, this type of education cannot lead a Korean multicultural society in the right direction. We objectively examined the reality of Korean society facing this crisis and presented policy changes regarding multicultural education through examining the case of France, which experienced a similar crisis prior.We are going to present the direction of change in multicultural education through the case of France which has experienced similar crisis before us by examining the reality of Korean society facing the crisis like this.

Cardiovascular disease has been the leading cause of death among patients with chronic renal failure. Many reports have been described that homocysteine is one of the independent risk factor to the occulsive vascular disease. In this study, HPLC/FLD (high performance liquid chromatography-fluorescence detector) technique was used to measure homocysteine level in patients with chronic renal failure and normal control group. The detection limit and recovery of total plasma homocysteine using HPLC/FLD were 98.6$\pm$5.8% and 0.2 nmol/ml, respectively. The linearity of this method was established in concentration range of 2~50 nmol/ml (correlation coefficient=0.9997). The concentrations of total plasma homocysteine were 6.81$\pm$1.54 nmol/ml and 27.28$\pm$14.94 nmol/ml in normal control (n=20) and patient group (n=90), respectively (p<0.05). In this study, the HPLC/FLD method showed high sensitivity and reproducibility for a routine clinical laboratory testing. Moreover determination of homocysteine level in plasma might be useful for a biochemical marker for predicting the cardiovascular diseases and for monitoring of therapeutic effect of lowering homocysteine in patients with chronic renal failure.

자연수를 가압(4~5기압)하면서 물과 공기의 비를 4:1~3:1로 혼합하면 수체 내 초미세기포(Diameter $3{\sim}10{\mu}m$)가 발생하는데 이를 산소용해수라 하며 수질정화시설 또는 양식장 등에 널리 사용되고 있다. 산소용해수의 특징은 기포의 비표면적이 넓고 10시간 이상 포화 농도를 유지하여 수체에 잔류하는 시간이 길기 때문에, 일반 산기석을 활용한 포기나 순산소 용해 등의 타 방법과 구별된다. 산소용해수의 산소전달효율은 기존 방법과 큰 차이를 보이기 때문에 실제 적용시에는 대상수를 이용하여 산소전달계수($K_{L}a$)를 사전에 산정할 필요가 있다. 본 연구에서는 한국건설기술 연구원의 안동 수자원 환경실험센터 내 실외형 콘크리트 사각반응수조에 산소용해장치 및 확산장치를 결합한 일체형 시스템을 적용시켜 2010년 9월~2011년 1월의 5개월간 결과를 분석, 본 장치의 $K_{L}a$를 산정 후 수질정화의 활용 면에서 검토하였다. $K_{L}a$의 산정에는 다양한 방법이 이용되나 용존 산소 농도의 제어에 한계가 있는 실외 대형실험장에 적합한 Lewis and Whitman의 Two-film 이론에 근거한 정상포기법을 적용하였다. 체적 $80m^3$의 수조 내에서 현장 유지용수를 대상으로 실험한 결과 산소전달계수는 $0.324\pm0.050$/min, 포화농도는 8.64 mg $O_2$/L, 도달시간은 11 /min이 산정되었으며, 이는 기존 산기석 포기의 산소전달계수 범위인 $0.105\pm0.019$ /min보다 약 3.1배 높은 결과를 보였다. 또한, 확산장치의 수류 순환 방향 및 정도를 검토하기 위하여 실험수조에서 1m단위로 격자를 구성한 후 초음파 유속계로 실측한 결과 0.0~2.5 m/s 의 평면적 유속범위를 도출하였다. 그리고 전체 순환을 고려했을 때 용존산소는 약 8시간 후 8.64 mg $O_2$/L 값에 도달하여 안정화 되었으며, 강한 수류순환과 산소용해수에 의해 하상에 존재하는 퇴적물들의 이송 및 산화촉진을 유도하였다. 이를 근거로 실험수조의 체적과 기준 가동시간인 8시간을 적용시켰을 때, 실험구 수질은 대조구와 비교하여 COD, T-N, T-P가 모두 25~35% 개선되었다. 이 결과는 여과공정 없이 단순 순환만을 고려한 물리적 수질정화 방법의 단독 활용 가능성을 나타내며, 기존 연구에서 나타난 SOD (Sediment oxygen demand) 저감 능력을 감안할 때 향후 폐쇄성 수역의 수질관리에도 효율적으로 활용할 수 있음을 시사한다.

Nepal is a landlocked mountainous country in South Asia, located between China to the north and India to the south, east, and west. As such, wastewater management has become one of the most significant problems in urban area of Nepal. In Nepal, the centralized wastewater treatment systems were dysfunctional due to high cost of operation, discontinuous power supply, lack of proper maintenance and proper technical workforce to address the issues. As such, constructed wetlands (CW) were applied to treat various secondary wastewater as alternative to wastewater treatment facilities. Generally, efficiency and sustainability of CW technology depends on proper operation and maintenance and active community involvement. This study summarizes information about 26 CW in Nepal. Specifically, factors including data banking, removal efficiency, quality of discharged water, compliance to water quality standard of Nepal and operation and maintenance were investigated. Considering removal efficiency per pollutant, Ka-1 achieved the greatest reduction for most pollutant followed by B-1, L-3, Ka-5 and K-1. Nepal has practiced CW technology for more than 2 decades but currently, development of technology was interrupted by the inefficient performance of existing facilities. Public awareness about the technology, natural disaster, unavailability of specified substrate materials, lack of fund for further research and experiments has hindered the expansion of technology. In spite of these concerns, CW was still proven as an alternative solution to the present wastewater problems in urban areas of Nepal.

The purpose of this study is to examine the characteristics of the location and the layout of Donghwa temple(桐華寺) in Kyungbuk Province from feng-shui perspective. Feng-shui is a traditional geographic thought in China and Korea. It is necessary to understand feng-shui in order to understand Korean landscape and cultural geography. Feng-shui had had a tremendous impact on Korean landscape through selective buildings of cities, settlements, houses, monuments, temples, pagodas, and so on. In this study, I interpret the geomantic characteristics of Dinghwa temple in Kyungbuk Province. The results of this study are as follow. 1) Donghwa temple is carrying the mountain on the back and belting the water in front. The mountains which encircle the auspicious place are accordance with the feng-shui theory. The watercourse which flows the temple is suitable. The feng-shui spot is located at the foot of the mountain with surrounding mountains and a watercourse in front. 2) Many feng-shui texts discuss the types of surrounding mountain in detail and morphologically describe them with certain auspicious objects. In case of Donghwa temple, it can be compared to a phoenix carrying eggs in the bosom. This is a morphological marker for the description of configulation features of Donghwa temple. In the case of Donghwa temple, we can observe geomantic landscape for the purpose of fulfilling the geomantic harmony of the temple. Also the impact of feng-shui on vegetation is identified in Donghwa temple. 3) For the management of good feng-shui condition, and for the maintaining the harmony between the building layout and surrounding landform, some proposals are suggested.

This study focus on the surface deterioration diagnosis based on the material characteristics of Taean Dongmunri Maaesamjonbulipsang(rock-carved standing triad Buddha Statue) and the weathering environment analysis. Rock materials of the triad Buddha is coarse-grained biotite granite which is composed mainly of quartz, K-feldspar, plagioclase, biotite and muscovite. The triad Buddha was serious surface irregularity(13.5%), exfoliation(12.3%) and discoloration(46.6%), and the physical characteristics using ultrasonic velocity appeared fourth grade (0.59, highly weathered). Korean style wooden shelter of the triad Buddha(closed type) maintained high humidity environment (daily mean; 86.6%) than exterior environment, and appeared the possibility of deterioration by freezing-thawing because the temperature showed below zero temperatures in winter. The shelter was changed from closed-type to open-type to relieve the moisture problem recently. But the moisture problem is yet to be solved because surface water flowing along northern wayside is flowed into triad Buddha. Therefore, environmental control will need to stop inflow of water into triad Buddha.

This study carried out current status, characteristics, and problems of coastal environment management on semi-enclosed Masan Bay in Korea and suggests cost-effective and eco-friendly water quality management policy. The pollutants from terrestrial sources into the Bay have apparently environmental pollution problems, such as eutrophication, red tide, and hypoxia. The carrying capacity of the Bay is estimated by hydrodynamic model and ecosystem model, material circulation including bivalve in ecosystem is analyzed by the growth model of bivalve. The resulting reduction in the input load was found to be 50~90%, which is unrealistic. When the efficiency of water quality improvement through bivalve farming was assessed based on the autochthonous COD, 30.7% of the total COD was allochthonous COD and 69.3% was autochthonous COD. The overall autochthonous COD reduction rate by bivalve aquaculture farm was found to be about 6.7%. This study indicate that bivalve farming is about 31% less expensive than advanced treatment facilities that remove both nitrogen and phosphorous.

The education of arts has been known to have positive impacts on not only general public but also for groups that have low self-satisfaction or that feel a sense of alienation. For example, there are research reports that confirm that there was a change in the sense of accomplishment and self-effectiveness on the students in industrial high schools that have less self-assurance and faith in their own identities compared to the academic high schools after taking art classes. Also, it has been discovered in another study on juvenile delinquents that how they spend their leisure time affected the rate of second convictions. In addition, in the , it has been shown that the juveniles preferred the cartoon and animation field the most among different art fields. The purpose of this research is developing a learning-teaching curriculum that can be used in the youth detention center schools based on above research results. The goal of the arts education in the youth detention center must be in increasing the inner control factors such as self-esteem and self-confidence rather than raising professional technicians for employment. Therefore, the researcher will understand the environmental particulars of the youth detention center which is closed and in which group works take the most proportion to develop and propose a teaching-learning curriculum most appropriate for such environment to conduct cartoon and animation education.

The purpose of this study was to investigate effect of psychotic patient after applying anger management video and tea gathering program to psychotic patient. This study was an experimental research and used nonequivalent control-group pretest-posttest design. Study subjects were 16 patients for an experimental group and 16 for a control group-32 in total- who were psychotic patients hospitalized in a closed ward in H mental hospital. The measurement variable is an aggressiveness scale, and the effect of the program was measured once after the video program and once after eight tea gathering. Data Analysis methods were real number and percentage, average and standard deviation, χ² test, t-test, paired t-test, and Repeated measure ANOVA. The aggression of an experiment group was significantly lower than the control group(F=14.38, p< .001). Aggressive sub-item, hostility (F=8.53, p< .001), anger (F=6.10, p=.004), verbal aggression(F=7.58, p< .001), physical aggression(F=13.92, p< .001) all of tte experiment group was significantly lower than control group. Based on these results, anger management programs can be used as basic data for anger control in psychotic patient or in various groups.

Since the hydraulic fracturing field testing method was introduced first to Korean geotechnical engineers in 1994, there have been lots of progresses in a hardware system as well as an interpretation tool. The hydrofracturing system of first generation was the pipe-line type, so it was not easy to handle. It had been modified to a wire-line system at their second generation. It was more compact one but it also needed an additional air-compressor. Our current system is much more compact and operated by all-in-one system, so it doesn't need an additional air-compressor. With a progress in a hardware system, the software for analyzing the in-situ stress regime has also been progressed. For example, the shut-in pressure, which is the most ambiguous parameter to be obtained from hydrofracturing pressure curves, can now be acquired automatically from the various methods. While the hardware and software for hydrofracturing tests are being developed during the last decade, the author could accumulate the field test results which can cover the almost whole area of South Korea. Currently these field data are used widely in a feasibility study or a preliminary design step for tunnel construction in Korea. Regarding the difficulties in a site selection and a test performance for the in-situ stress measurement at an off-shore area, the in-situ stress regime obtained from the field experiences in the land area can be used indirectly for the design of a sub-sea tunnel. From the hydrofracturing stress measurements, the trend of magnitude and direction of in-situ stress field was shown identically with the geological information in Korea.
