Objectives : Patients with organic brain lesion can produce unique slow waves (delta and theta) in the EEG. Basic assumption of this study was that the low resolution electro magnetic tomography (LORETA), an inverse source localization program, can provide functional images representing increased slow wave activity in these patients compared to normal subjects. Methods : The current study was performed by 18 channels digital EEG for 10 patients whose organic deficit have been Visually confirmed by CT or MRI. The source images of slow wave (1-7 Hz) frequency were produced by LORETA-key program. Results : We found that in eight out of ten subjects, LORETA successfully found out the source regions which were very closely matched to their original brain lesions. However in two subjects whose organic brain lesions were too small (<1cm) and located out of gray matter, we failed to find any increased slow wave activity compared with normal control. Conclusion : We can conclude that LORETA could be a useful method to provide functional imaging in patients with gray matter deficits in their brain. Its usefulness and limitations were discussed.

유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

The window in architecture has a mysterious role connecting the indoor and outdoor world and also an interaction. this study investigates the functions of the past and present windows and its functions which will be required in future and aims a t seeking a planning direction of desirable window by integrating the understanding of window plan in outdoor space of building and new design techniques. The origin of window and its developmental process are expressed primarily by internal functions and it has been discussed from the external viewpoint with the development of structure, materials and social and cultural aesthetic sense. Accordingly it describes the history and place of windows to define the functions of windows and Chapter 2 states the forms, functions and treatments of window opening part according to the times. Chapter 3 cites the cases of the prototypes of forms shown in the outside of building as the functional and design elements windows in building. Chapter 4 suggests the positive cases of window prototype which produces the outdoor space of modern architecture and examines the correlation of it to the various elements according to the objective methods and order on the basis of SD method. Consequently, the windows in building should be planned by considering the following: 1. The window must be faithful to its original purposes. 2. It should be based on a great design because it is an important part which shows the appearance of building in urban area. 3. As today's buildings are large-scaled and high storied and also have unique characteristics, the development of construction technique and the production of good materials and products should be made. 4. The various general factors of windows should be analyzed and considered in planning windows as well as its design and technical sides.

OIL SPILL AND REGIONAL CO-OPERATION ON MARINE POLLUTION PREPAREDNESS AND RESPONSE IN THE NORTHWEST PACIFIC

Chang-Gu Kang(강창구),Seong-Gil Kang(강성길),Jeong-Hwan Oh(오정환) 한국해양환경·에너지학회 2005 한국해양환경공학회 학술대회논문집 Vol.2005 No.11

The sea area of the far-eastern Asian countries - that is, Northwest Pacific region, was regarded as the area facing the highest risk of oil spill in the world. In fact, 19 major oil spills (greater than 1,000 tons), 124 intermediate spills (50 ~ 1,000 tons), and innumerable small spills (less than 50 tons) have been occurred in the area from 1990-2004. Based upon the perception of high risk of oil spill, the four countries bordering the Northwest Pacific (China, Japan, R. Korea and Russia) have developed effective measures for regional cooperation in marine pollution preparedness and response within the framework of the Northwest Pacific Action Plan (NOWPAP), which was established in 1994 as a Regional Seas Programme of the United Nations Environment Programme (UNEP). MERRAC, as one of four Regional Activity Centers of NOWPAP, has been responsible for regional co-operation on marine pollution preparedness and response in the region. For the purpose of providing an operational mechanism for mutual assistance during major oil pollution incidents in the region, MERRAC has especially developed the NOWPAP Regional Oil Spill Contingency Plan (Plan) and its Memorandum of Understanding (MoU), which was officially come into effect on being signed by all NOWPAP Members. Now, the four countries of the NOWPAP region are in a better state of preparedness to respond to oil spills, as each of them may request assistance from the other three NOWPAP members in cases of large oil spill emergencies. The present paper introduces current activities of MERRAC as a new regional initiative on marine pollution preparedness and response in the NOWPAP region, together with analysis of oil spill risk in the region and regional preparedness and response system to oil spill, with a special reference to NOWPAP Regional Oil Spill Contingency Plan.

Purpose : This study is to investigate that influence of dominant eye on the neural mechanisms involved in visual inputs system using ERPs which are neural signals that reflect neural activity. Methods : Twenty three normal controls adults with right dominant eye and twenty normal controls adults with left dominant eye participated in this experiment. In initial screening, we had neuropsychological test with BAI and BDI-2. All participants had normal or corrected visual acuity 20/20. Edinburgh Handedness Inventory was carried out to select right-handed. To identify dominant eye, the hole-in- card test was executed repeatedly three times. To assess whether influence of dominant eye on the neural mechanisms involved in visual inputs system, event-related potentials (ERPs) were recorded with electroencephalography. Performance measure was the reaction time (RT). The ERPs in response to dominant eye in respect of visual field were investigated in three regions: the temporal-occipital, the occipital and the parietal regions. Especially, the P100 amplitude in occipital region, N170 amplitude in temporal-occipital region and the P300 amplitude in parietal region were explored. Results : A significant difference in RT was observed between the RVF and LVF, which the RVF exhibited shorter RT than the LVF with right hand in left dominant eye (t=-5.47, p<0.001). P100 latency showed that the RVF had shorter latency than the LVF with right hand in right dominant eye (p<0.001). N170 amplitude revealed that the RVF had larger amplitude than the LVF with right hand in right dominant eye (p<0.001). N170 latency revealed that the RVF had shorter latency than the LVF with right hand in right dominant eye (p<0.001). P300 amplitude and latency were no main effect for dominant eye. Conslusions : This present study has attempted to establish the influence of dominant eye on the neural mechanisms involved in visual inputs system. The conclusion which can be drawn from this study are that visual stimuli incoming from the RVF or LVF are differently recognized depends upon each dominant eye. That is, while the participants with right dominant eye responded more actively on stimuli coming from LVF than RVF when they conducted the experiment with their left hand, the participants with left dominant eye responded more actively on stimuli coming from RVF than LVF when they conducted the experiment with their right hand.

Contralateral axillary lymph node metastasis (CAM) is classified into synchronous and metachronous CAM. It is considered a stage IV disease by American Joint Community on Cancer (AJCC) cancer staging system. Although ipsilateral breast tumor recurrence (IBTR) with metachronous CAM is rare, it can occur after previous axillary lymph node dissection (ALND) because of altered lymphatic drainage. Metachronous CAM might be a regional disease progression rather than a distant metastasis. Here, we present a case of IBTR with metachronous CAM. This patient was treated with curative intent. The management of CAM remains controversial.
