In a case of driving beginnners, it is very difficult to park a car perfectly because driver's knowledge makes more errors than intelligent mechanism when they are performed repeatedly. However skilled drivers be of experienced knowledge are able to park a car quickly. In this paper, we analyzed driving patterns of skilled drivers, designed the fuzzy controller to park based on it, and perform auto-parking simulation of a car using that controller.

Son, Cheol-Hun,Bae, Jae-Ho,Shin, Dong Yeok,Lee, Hong-Rae,Choi, Yung Hyun,Yang, Kwangmo,Park, You-Soo Informa Healthcare 2013 Immunological investigations Vol.42 No.4

<P>Dendritic cells (DCs) are potent antigen-presenting cells that can be matured <I>in vitro</I> from immature dendritic cells (iDCs) in the presence of several biological agents such as cytokine cocktail, CD40L, TNF-a and antigen loading, which are necessary and achieved using various protocols, such as lipofection, passive pulse or electroporation. However, these DCs maturation protocols may cause with a significant loss of cells because of cellular attachment and spreading during culturing. Some biomaterials that influence adhesion and development of cells have been used in cell culture techniques, and it was thought that they might be applied on the culture of DCs. In this study, we used polyHEMA, which is a hydrogel coating biomaterial that prevents DCs from adherence, and investigated whether hydrogel coating affects the maturation of iDCs. The efficiency in the generation of mDCs was improved through hydrogel coating procedure and a dendritic cell maturation marker, CD83, was significantly increased in hydrogel-coated culture condition. The antigen-loaded mDCs from electroporation were further expressed the CD83. The mDCs generated in the hydrogel-coated culture condition showed more, longer and thicker dendrites, and produced more amounts of cytokines such as IL-12 and IFN-γ. Therefore, it was suggested that the hydrogel-coated culture condition could improve function of mDCs.<fn><P>Cheol-Hun Son and Jae-Ho Bae contributed equally to this work.</P></fn></P>

국내 팔색조(Pitta nympha) 분포 현황을 알아보고자 전국 국립공원 등 보호지역 중심으로 총 19개 지역을 조사하였고, 전문가 네트워크를 통해 자료를 보강하였다. 전국 19개 지역을 조사한 결과 북한산, 지리산 등 내륙지역 7개 국립공원에서는 팔색조가 확인되지 않았고, 경남 거제, 남해, 해남, 장흥 고흥 등 남해안과 인접한 12개 지역에서 팔색조 서식이 확인되었다. 또한 전문가 네트워크를 통해 수집한 팔색조 출현 위치 정보 82건을 분석한 결과, 전국 8개 광역지자체 모두 팔색조 서식이 확인되었고, 내륙지역(26.8%)보다 해안지역(73.2%)에서 더 많이 출현하였다. 연구 결과를 종합해보면, 우리나라의 팔색조는 주로 제주도와 남해안 지역을 중심으로 많이 분포하며, 그 보다 적은 개체수가 내륙 지역에 넓게 분포하고 있는 것으로 나타났다. The present study investigated the current distribution of Fairy Pitta (Pitta nympha) in South Korea. A total of 19 study areas, including protected areas such as national and provincial parks in South Korea were surveyed, and additional data obtained from an expert network. According to the results, Fairy Pitta was absent in seven inland national parks, including Mt. Bukhan and Chiri parks. Fairy Pitta inhabited 12 areas near the southern coast of South Korea, including Geoje, Namhae, Haenam, Jangheung, Goheung, and Gyeongnam Province. The analysis results of 82 datasets obtained from experts with regard to the locations where Fairy Pitta have been spotted showed that the bird inhabits all the eight metropolitan regions in South Korea, and is more frequently spotted in coastal areas (73.2%) than in inland areas (26.8%). The findings demonstrate that Fairy Pitta is mainly distributed in Jeju Island and the southern coast of South Korea, and is distributed in inland areas at relatively lower numbers.

Elevational Distribution of Breeding Bird Communities in Seoraksan National Park, Korea

Hwang, Hyun-Su,Lee, Jae-Kang,Eom, Tae-Kyung,Bae, Ho-Kyoung,Lee, Dong-Ho,Lim, Jong-Hwan,Jung, Sung-Cheol,Park, Chan-Ryul,Rhim, Shin-Jae Korean Society of Forest Science 2020 한국산림과학회지 Vol.109 No.1

In this study, the elevational distribution of breeding birds in Seoraksan National Park, Korea was investigated. Forty-six species of birds were documented from line transect surveys taken from Seorakdong at 230 m above sea level (a.s.l.) to the Daechungbong summit at 1708 m asl. Birdspecies richness and diversity were highest in Seorakdong and lowest at the Daechungbong summit. As elevation increased, bird species richness and diversity decreased, with a humped-shape trend being observed between 700 m and 1200 m a.s.l. Stepwise analyses revealed that breeding bird species diversity indices were significantly negatively correlated with elevation (r² = 0.327, P < 0.001) and positively correlated with vegetational coverage (r² = 0.324, P = 0.046). Higher elevations supported fewer birds than low and intermediate elevations. Projections at the local scale, including data on behavior and habitat use by birds, will be necessary for optimal conservation and management of the bird communities in Seoraksan National Park.

Tuberculous peritonitis is discovered from sixty to ninty percent of pulmonary tuberculosis patients. Clinical symptoms are nonspecific such as mild fever, weakness and malaise but show tenderness in right lower abdomen and abdominal distension. Diagnosis is confirmed by laparoscopic and pathologic findings. We report a case of tuberculous peritonitis in an 11-year-old boy who was hospitalized because of abdominal distension with pain on right lower abdomen which had developed one day before he came to hospital. Chest X-ray showed pleural effusion on both sides. We did laparoscopic examination and observed diffuse nodular infiltration. In biopsy specimen we observed osseous granuloma and acid-fast bacilli in AFB stain.

박정래,박종욱,이수일,이철호,오차재,김창원,조병만,김돈균 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.3

목 적 : 진폐증은 분진으로 인해 인체의 면역기전이 작용하여 폐섬유화가 진행되는 질환으로, 인체의 면역기전에 작용하는 구리와 아연은 진폐증의 병리적인 진행과정인 폐섬유화에 관여한다. 본 연구의 목적은 초기진폐증 유소견자와 진행된 진폐증 환자의 혈청 구리와 아연의 농도를 정상인과 비교함으로써 체내 구리와 아연의 농도가 진폐증의 섬유화의 진행정도에 따라 변동함을 밝히고, 이를 이용하여 폐섬유화의 진행정도를 추정할 수 있는 지표를 제시하고자 한다. 방 법 : 진폐정밀기관에 내원한 초진내 원자 100명과 진폐요양기관에 입원한 진폐증 환자 100명을 선정한 후 흥부사진소견을 ILO 분류법의 진폐진행정도에 따라 각각 세 군(Stage Vl, V2, V3 & Stage Pl, P2, P3)으로 구분한 후 각 군의 혈청구리와 아연의 농도를 비교분석하였다. 대조군으로는 폐결핵, 심근경색, 뇌경색을 경험한 적이 없는 일반인 100명을 선정하였다. 결 과 : 초진내 원자군의 혈청 구리농도는 섬유화의 진행단계에 따른 유의한 차이를 보였으며, Stage V3에서 가장 높았다. 입원환자군에서는 혈청 구리농도가 대조군과 유의한 차이를 보이지 않는데 (p=0, 152), 이는 입원환자의 불량한 영양상태와 건강상태 때문인 것으로 추정된다. 초진내원자군과 입원환자군의 혈청 아연농도는 섬유화의 진행에 따라 통계적인 차이를 보였으며, Stage V2와 Stage P2, P3에서 각각 대조군에 비해 유의하게 낮았다. 혈청 아연과 구리농도의 비또한 양군에서 섬유화의 진행에 따라 의미있게 높았는데, 섬유화가 현저히 진행된 단계 (Stage V3, Stage P2, P3)에서 대조군과 의미있는 차이를 보였다. 결 론 : 초진내 원자와 입원환자의 혈청 Cu/zrl 비는 섬유화의 진행정도가 현저할수록 대조군에 비해 유의하게 높게 나타났다. 진폐증 환자들의 혈청 Cu/zn 비는 진폐증의 폐섬유화의 진행정도를 추정함에 있어 상당히 유용한 지표로 이용될 수 있으며, 폐섬유화의 진행과정에서의 혈청 구리와 아연의 작용기전을 이용한 치료방법의 마련에도 도움이 될 것으로 판단한다. Objectives : Copper and Zinc, the trace elements of a living body, take a part in immunologic mechanism and induce the pulmonary fibrosis which is the pathologic progress of pneumoconiosis. This study was performed to assist the identification of the pathologic process of pulmonary fibrosis in pneumoconiosis. Methods : The subjects of thls study was 200 diagnosed persons as pneumoconiosis, of whom 700 persons was the visitors in the outpatients departments of pneumoconiosis and 100 admissive pneumoconiosis patients. The serum copper and zinc are measured and compared. Results : The mean serum copper concentration of visitor group was significantly higher than that of control group, and that of stage V3 subgroup of visitor group was highest because of their advanced fibrosis. But, there was not the difference of serum copper concentration between patient and control group. We thought that the reason was poor nutritional and health status of the patient. The mean of serum zinc concentration of visitor and patient control was lower than that of control group. As the degree of pulmonary fibrosis was more severe from stage Vl, V2, V3 of visitor to stage Pl, P2, P3 of patient, the mean of serum zinc concentration was lower. The ratio of serum copper/zinc of visitor and patient was higher than that of control, and that of patient was higher than that of visitor. Those results showed that the ratio of serum copper/zlnc ratio more greatly expressed the degree of progression of pneumoconiosis than only copper or zinc concentration by adjustment of nutritional and health status of the patient. Conclusions : As above study results, the degree of pulmonary fibrosis of pneumoconiosis could be estimated by means of serum copper/zinc ratio.
