  • Low level laser therapy (LLLT) has facilitated an improvement in acupuncture treatment. In this study, we stimulated Shaochong (HT9), Dadun (LR1), Shaohai (HT3), and Yingu (KI10) acupoints with pulsed laser diodes 532 nm [green laser] and 658 nm [red laser] in rats with induced middle cerebral artery occlusion(MCAO). The animals were divided into 6 groups: intact control; MCAO control without LLLT; LLLT with red laser at HT9·LR1 and HT3·KI10 (RR); LLLT with green laser at HT9·LR1 and HT3·KI10 (GG); LLLT with green laser at HT9·LR1 and red laser at HT3·KI10 (GR); and LLLT with red laser at HT9·LR1 and green laser at HT3·KI10 (RG). We evaluated the immunohistochemical changes in the hippocampal CA1 region, and complete blood count changes. Compared to the MCAO control group, the RG group showed a significant decrease in Bax and cytochrome c levels in the hippocampus, and a significant increase in hemoglobin level, hematocrit, total white blood cell, neutrophil, lymphocyte, monocyte, and erythrocyte counts.

  • Objectives The purpose of this study was to analyze the Sasang constitution and psychological traits of amyotrophic lateral sclerosis (ALS) patients and to utilize the results in treatment and management. Methods The differences of Sasang Constitution distribution, psychological characteristics, comorbid disorders between ALS group of 26 patients and general group of 1132 persons were investigated and analyzed. Results There was no significant different distribution of Sasang Constitution between ALS group and general group but there was Yang-like personality tendency in ALS group than general group. In overall constitution, ALS group had the high prevalence rate of musculoskeletal disorders and diabetes than general group. In Soyangin constitution, ALS group had a high prevalence rate of musculoskeletal disorders than genral group. In Taeeumin constitution, ALS group had a high prevalence rate of diabetes and hypertension than general group. Conclusion ALS patients have the Yang-like personality. It is due to the adaptation of personality on the environmental change or coping strategy on diseases rather than the characteristics of congenital Sasang Constitution.

  • This study deals with the formation of Jongyeonbangjeok's Gwangju Factory in the 1930's to 80's, and the findings are shown below: In the period of formation, the factory was rectangular-shaped from north to south, and the structure was located at the center of the site, and in the east of it, there was a dormitory connected from south to north. The building was arranged with an open area on the south. In the east of the site where company houses were located, same-sized structures were arranged along the axis.In the period of change, the factory was restored about the damage from the Korean War, and it went through the process of division into two companies. As a result, the factory in the center of the site was divided into left and right ones, and the dormitory and the group of company houses were, too, divided into two, so division was made largely into southern and northern parts. In the period of stabilization, along with factory extension in each of the companies, welfare for factory workers was expanded by building more houses or opening sport facilities. After the 1980's, too, the existing factories were either extended or remodeled according to the induction of equipment, and some showed changes in their functions due to a fire or such.

  • Since the multi-view video is a set of video sequences captured by multiple array cameras for the same three-dimensional scene, it can provide multiple viewpoint images using geometrical manipulation and intermediate view generation. Although multi-view video allows us to experience more realistic feeling with a wide range of images, the amount of data to be processed increases in proportion to the number of cameras. Therefore, we need to develop efficient coding methods. One of the possible approaches to multi-view video coding is to generate an intermediate image using view interpolation method and to use the interpolated image as an additional reference frame. The previous view interpolation method for multi-view video coding employs fixed size block matching over the pre-determined disparity search range. However, if the disparity search range is not proper, disparity error may occur. In this paper, we propose an efficient view interpolation method using initial disparity estimation, variable block-based estimation, and pixel-level estimation using adjusted search ranges. In addition, we propose a multi-view video coding method based on H.264/AVC to exploit the intermediate image. Intermediate images have been improved about $1{\sim}4dB$ using the proposed method compared to the previous view interpolation method, and the coding efficiency have been improved about 0.5 dB compared to the reference model.

  • 차세대 방송서비스 개발의 일환으로 관심을 모으고 있는 다시점 비디오 부호화(multi-view video coding, MVC) 방식은 인접한 여러 대의 카메라로 동시에 획득한 영상을 효과적으로 압축하는데 그 목적이 있다. 이때, 중간시전 영상을 생성하여 부호화하는 과정의 참조영상으로 이용할 수 있으며, 이를 위해서는 다시점 비디오 특성에 맞는 영상보간 방법이 필요하다. 기존에 제안되었던 영상보간법은 변위의 검색범위를 초기에 설정하여 블록정합을 이용하여 화소 단위로 변위를 측정하기 때문에 카메라 사이의 거리가 크거나 객체의 움직임이 커서 변위의 변동이 심한 영상에서는 안정적인 화질의 영상을 얻기 어렵다. 또한, 고정된 크기의 블록을 이용하여 전체 변위를 측정하므로 객체의 변위차가 큰 영역에서 변위 오류가 많이 발생한다. 본 논문에서는 이와 같은 문제를 해결하여 보다 개선된 화질의 중간시점 영상을 얻기 위한 새로운 영상보간법을 제안한다. 영역분할을 이용한 초기의 변위측정 과정에서, 처음부터 최대 변위의 범위를 설정하는 대신에 블록 단위로 대략적인 변위륵 측정한 후에, 가변 블록을 이용하여 보다 세밀한 변위를 측정한다. 이 방법은 변위차가 큰 객체의 경계 부분에서 보다 정확하게 변위를 측정 할 수 있으므로, 화소 단위로 변위를 측정할 때 이전에 추한 변위 정보를 바탕으로 각 화소별로 검색 범위를 설정한다. 적응적으로 설정된 검색 범위를 이용하여 화소 단위의 변위를 측정하면 보다 개선된 변위를 얻을 수 있다. 추가적으로, 변위측정 과정에서 발생하는 변위의 오류를 최대한 줄이기 위해 각 단계별로 미디언 필터를 이용하여 변위 오류를 수정하였다. 본 논문에서 제안한 방법으로 실험한 결과 기존의 영상보간 방법보다 화질이 약 $1{\sim}4dB$ 정도 개선되었다.필, 투명도 등을 위성원격탐사 자료와 GIS를 이용하여 공간분석을 실시하고, 공간분포도를 작성함으로써 대상해역의 해양환경을 파악하였다. 본 연구결과, 분석된 위성자료가 현장조사에 의한 검증이 이루어지지 않을 경우, 영상자료분석을 통한 표층수온 추출은 대기 중의 수증기와 에어로졸에 의한 계산치의 오차가 반영되기 때문에 실측치 보다 낮게 평가 될 수 있으므로, 반드시 이에 대한 검증이 필요함을 알 수 있었다. 현지관측에 비해 막대한 비용과 시간을 절약할 수 있는 위성영상해석방법을 이용한 방법은 해양수질파악이 가능할 것으로 판단되며, GIS를 이용하여 다양하고 복잡한 자료를 데이터베이스화함으로써 가시화하고, 이를 기초로 공간분석을 실시함으로써 환경요소별 공간분포에 대한 파악을 통해 수치모형실험을 이용한 각종 환경영향의 평가 및 예측을 위한 기초자료로 이용이 가능할 것으로 사료된다.염총량관리 기본계획 시 구축된 모형 매개변수를 바탕으로 분석을 수행하였다. 일차오차분석을 이용하여 수리매개변수와 수질매개변수의 수질항목별 상대적 기여도를 파악해 본 결과, 수리매개변수는 DO, BOD, 유기질소, 유기인 모든 항목에 일정 정도의 상대적 기여도를 가지고 있는 것을 알 수 있었다. 이로부터 수질 모형의 적용 시 수리 매개변수 또한 수질 매개변수의 추정 시와 같이 보다 세심한 주의를 기울여 추정할 필요가 있을 것으로 판단된다.변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을 발견하였다. 이상의 행태적 측면과 투자성과측면의 실증결과를 통하여 한국주식시장에 있어서 시장수익률을 평균적으로 초과할 수 있는 거래전략은

  • A lot of relics were unearthed in the Shinchang-dong wetland site, which can help restore prehistoric life style, including construction tools such as wood doors, wood hammers, ax handgrips, sickle handgrips, wedges, awls, wood pillars and connection members, food vessels made of earth or wood and fish, shell fish, seeds and remains of weapons. In particular, a door was found in the site, which was measured at 110cm long and 37cm wide. If restored it will be 75cm wide. The door seems to date back as far as the 1st century B. C., which would be the oldest one ever discovered in Korea. This paper is intended to explore the implications of the door by investigating the environment of the Shinchang-dong wetland site bearing the relics intact, manufacturing techniques and times of manufacturing of the door as well as attributes of doors presented in the literature related to old time architecture such as Goguryeo tomb paintings and house-shaped vessels. It also intends to provide basic data for study of residential architecture in prehistoric times.

  • A 3-month-old female Maltese puppy was hospitalized with persistent diarrhea in a local veterinary clinic. Blood chemistry and hematology profile were analyzed and fecal smear was examined. Diarrheal stools were examined in a diagnostic laboratory, using multiplex real-time polymerase chain reaction (PCR) against 23 diarrheal pathogens. Sequence analysis was performed using nested PCR amplicon of 18S ribosomal RNA. Coccidian oocysts were identified in the fecal smear. Although multiplex real-time PCR was positive for Cyclospora cayetanensis, the final diagnosis was Cystoisospora ohioensis infection, confirmed by phylogenetic analysis of 18S rRNA. To our knowledge, this the first case report of C. ohioensis in Korea, using microscopic examination and phylogenetic analysis.

  • This study was to examine the effects of teacher's encouraging language on elementary student's adjustment to school life. To achieve this purpose, teacher's encouraging language were drawn from Adlerian literatures and ten principles of encouragement were established as the following: recognizing the student's values and potentials, putting an emphasis on student's positive sides, helping the student realize his or her own strength, tolerating student's mistakes, using perceptual alternatives, practicing self-encouragement, accepting and supporting opponents, stimulating internal motivations, and emphasizing social usefulness. Subjects were 34 1st graders at J elementary school in CheonNam. 17 subjects were assigned to experiment group and 17 subjects were assigned to control group. Teacher's encouraging language were applied to experiment group and teacher's usual languages were provided to control group for ten weeks. The quantitative data were collected through Elementary school adjustment behavior rating scale(Oh, 2009) and were analysed via ANCOVA. The qualitative data were collected through observations and products of the subjects and were analysed via qualitative methods. The results showed that teacher's encouraging language had a positive effect on the student's adjustment to school life.
