This paper is aimed to examine the current research and educational problems of foreign studies in Korean universities and review some alternative ways. Area studies as foreign studies have several characteristics which are different from those of the other research disciplines. It is a research and educational program that promotes comprehensive understanding about political, economic, social, and cultural phenomena of a specific area in the world. For better understand 'others', researchers in the field of area studies must explain the whole mechanism of the area, which could be revealed in terms of the very existence of its reality. Foreign studies are accomplished with joint-research method, collaborating two or more different research disciplines and based on the contemporary system of knowledge accumulation and educational program. Therefore, the critical issue can be gradually taken on a political and social characteristic. At this point, research and educational manner in foreign studies field in Korea should be changed to secure the academic reflections of temporality, sociality, placeness using a new paradigm such as complexity.

비디오 스티칭은 카메라 간 변환 관계인 호모그래피를 이용하여 스티칭하는 것이 일반적이다. 본 논문은 호모그래피를 이용한 고정형 비디오 스티칭에서 조도 변화, 노이즈 등으로 일관되지 않는 특징점 추출과 유니폼한 입력 영상으로 적은 특징점이 추출되는 경우에 대하여 정확도 높은 호모그래피 추출이 가능한 특징점 누적 기반 고정형 비디오 스티칭 방법을 제안한다. 실험을 통해 단일 프레임 특징점을 이용한 결과 영상에 비해 특징점 누적을 이용하는 경우 영상 내 부정합 영역 등의 왜곡이 크게 감소하였음을 확인하였다.

Objective: The purpose of this report is to prove the clinical effect of Platycodon grandiflorum aqueous extract on pneumoniae patients. Methods: We used the aqueous extract of Platycodon grandiflorum to treat two pneumoniae patients. It was injected into five acupuncture points, which was Chondol(天突:CV22) 1 point, Pyesu(肺兪 : BL13) 2 point, and Kworumsu(厥陰兪: BL14) 2 point. Results & conclusions: We have used the aqueous extract of 24-year-old JK for treating the patients suffering from lung diseases, and have experienced the actual effects. Of the treated, two pneumonia-involved patients showed apparent improvement in simple chest X-ray and clinical symptoms. The patients were treated with JK (Jang-saeng platycodon) aqueous extract 25 and 22 times individually. The results were as follows. 1. The symptoms including coughing, phlegm, and fever were improved in two cases. 2. The lung infiltration in simple chest X-ray decreased and the WBC count was kept within normal range in two cases. 3. Side effect such as itching was not found in the process of JK aqueous extract treatment. 4. The criteria for pneumonia are fever, coughing with purulent phlegm, pleural chest pain, the evidence of new infiltration in simple chest X-ray, sign of lung sclerosis in auscultation, increase of WBC count, etc. But they may not be the proper objective diagnostic standards. So we had trouble in statistic process and numerical interpretation. Putting these results together, the JK aqueous extract is considered to be effective in treating patients for pneumonia, and the continuous research and accumulation of data is needed.

Purpose: The purpose of this study was to verify the influence of health point system on the lifestyle among the patients with chronic diseases listed in iCDMS, a project of the Incheon Metropolitan Center for Chronic Disease Control and Prevention. Methods: The data were collected 1,000 persons among the patients listed in iCDMS from March 16, 2009 to December 21, 2010 by telephone survey. The data were analyzed by descriptive statistics, ${\chi}^2$-test, odds ratio and logistic regression with the SPSS 18.0 program. Results: The higher the percentage of the accumulation of the points of necessary medical examinations they have, the better the lifestyle the participants practice moderation in drinking, exercise, and diet (p<.05). Also the higher the percentage e accumulative points of education and visit, the stronger the intention to improve the lifestyle such as for example, receiving the guidance of no smoking, giving up drinking, or being conscious of nutrition and obesity (p<.05). Conclusion: This study suggests that the motivation through an incentive system can increase self-care make an effect on the care of patients with chronic diseases.

This study was conducted to evaluate the effects of reduced nitrogen (N) and potassium (K) fertigation as additional fertilizer on tomato yield and nutrient contents in excessively nutrients-accumulated soil. Shoot and root dry weights (DW), dry matter rate for shoot, root and fruit and number of fruit in both AF50 and AF100 (50 and 100% levels of additional fertilizer) treatments were increased in comparison with those in AF0 (0% level of additional fertilizer) treatment. In case of nutrient uptake by tomato, nitrogen, phosphorous (P) and potassium contents in all tomato parts (leaf, stem, root and fruit) in AF50 and AF100 treatment were lower than those in AF0 treatment. On the contrary, soluble sugar and starch contents in all tomato parts in AF50 and AF100 were higher than those in AF0 treatment. There were differences between AF0 and AF50 or AF100 in tomato growth, yield, nutrient level and contents of soluble sugar and starch. In contrast, the level and initiation point of fertigation did not significantly affect the parameters. Based on our results, the application of properly reduced level of additional fertilizer is possible to maintain the productivity of tomato and alleviate the nutrient accumulation in plastic film house soils.

Organic amendments such as animal waste compost, lime-bordeaux mixture, and lime sulphur mixture contain heavy metal(loid)s which are toxic to human being, animal, and plant. The objective of this study was to compare heavy metal(loid)s contamination of soil between conventional and organic farm. Soil samples were collected from 10 conventional and 38 organic fruit farms. At each sampling point, top (0~15 cm) and sub soil (15~30 cm) were taken using hand auger. Total concentration for arsenic (As), cadmium (Cd), copper (Cu), nikel (Ni), lead (Pb), and zinc (Zn) in the collected soil were measured. The pollution index (PI) for heavy metal in organic farms indicated it was unpolluted area. However, mean value of PI for organic farms (0.143) was higher than that for conventional farms (0.122). High Geoaccumulation index (Igeo) for Cu, Pb, and Zn implied that grape farms were more polluted than others fruit farms because a lot of lime-bordeaux mixture and lime sulphur were applied in organic grape farms. Especially, top soils showed higher level of contamination than sub soil. Based on the above results, organic amendments might cause accumulation of heavy metals in soil. Therefore, particular attention should be paid for concentration of Cu, Pb, and Zn, when organic amendments are used in the organic fruit farms.

최근 유역으로부터의 유출량을 산정기법으로 NRCS-CN기법이 많이 활용되고 있다. 그러나 NRCS-CN 기법은 면적가중치 개념을 도입함으로써 토지이용의 공간적 분포에 따른 유출특성을 반영하지 못하는 단점을 내포하고 있다. 따라서 본 연구에서는 저류를 반영하는 Moglen(2000) 이론을 FORTRAN을 이용해 개발한 흐름누적 산정 알고리즘에 도입함으로써 CN의 공간적 분포를 반영할 수 있는 기법을 개발하고자 한다. 본 연구에서 개발된 기법과 기존의 area-weighted CN기법을 시험유역에 적용하여 비교검토를 실시하였으며 그 결과 토지이용 변화에 따른 유출특성을 개념적으로 잘 반영하고 있음을 확인하였다. 또한 개발된 기법은 기존의 기법에 비해 유출량을 작게 예측함도 알 수 있었다. 결론적으로 본 연구에서는 실제 유출현상에 보다 더 근접한 유출예측을 가능하게 하는 새로운 기법을 제안하였으며 본 연구결과는 향후 유역개발을 위한 유출최소화 설계에 활용될 수 있을 것으로 기대된다.

국내 지상파 DMB방송 표준에서는 2003년 말 국제 표준으로 제정한 MPEG-4 BSAC(Bit Sliced Arithmetic Coding) 오디오 복호화 방식를 표준으로 채택하였다. 본 논문에서는 MPEG-4 BSAC 오디오 복호화기의 주요 도구 및 모듈에 대해 32비트 고정소수점 연산으로 구현하고 ARM926EJ-S 프로세서에 인라인 어셈블리(Inline Assembly)를 적용하여 최적화 한다. 최적화에 대해 본 논문에서는 RISC프로세서인 ARM926EJ-S의 Core Cycle을 가장 높게 발생시키는 곱셈 및 MAC(Multiply And Accumulation)연산에 집중한다. 그리고 각 모듈 및 도구에서 빈번히 발생하는 곱셈 연산과 MAC연산의 처리를 효율적으로 하기 위하여 대상 프로세서인 ARM926EJ-S에서 사용 가능한 ARMv5용 어셈블리 명령어를 분석하여 사용한다. 최적화된 결과는 MIPS(Million Instruction Per Second)를 기준으로 평가한다. 구현 결과는 96kbps BSAC bitstream을 65MHz CPU clock에서 실시간으로 디코딩할 수 있음을 보여준다.
