1987년 6월과 8월 2회에 걸쳐 珍島內의 7개 調査地点에서 淡水魚類의 분포, 生態 및 形態등을 조사하였다. 총 採集個體數는 2,753個體로 同定 결과는 9科 24屬 30種으로 밝혀졌으며 Pseudorasbora parva, Hemiculter eigenmanni, Abottina rivularis, Aphyocypris chinensis, Acanthorhodeus gracilis, Misgurnus mizolepis 등 6種의 1次 淡水魚와 Trachydermus faciatus, Tridentiger obscurus, T. trigonocephalus, Acanthogobius elongata, A. hasta, A. lactipes, A. flavimanus, Acentrogobius pflaumi, Pseudogobius masago, Mugilogobius abei, Chaenogobius annularis, C. mororanus, Periophthalmus cantonensis, Fugu niphobles 등14종 2次 또는 周綠性 淡水魚가 珍島에서 처음으로 그 분포가 확인되었다. 본 지역에서 採集된 1차 담수어 중 Abottina rivularis, Acanthorhodeus gracilis는 지금까지 어느 島嶼地方에서도 分布가 확인된 적이 없는 種이며, Cobitis longicorpus, A. gracilis는 韓國特産種으로 그중에 C. longicorpus는 珍島가 육지로부터 분리되기 전에 分布되었던 種으로 그리고 A.gracilis는 2次的인 이동에 의해 분포된 種으로 생각된다. 쌍계천 상류지역인 st.1(쌍계천계곡)과 st.3(창포교 일대)에서는 섬의 상류ㅣ지역의 전형적인 특징종인 M.oxycephalus, O. latipes가 st.4(송정저수지)와 st.7(둔전저수지)에서는 혼탁한 수질상태에서 주로 서식하는 H.eigenmanni, P.parva, C.auratus, A.rivularis 등이, st.6(금갑리)와 st.7(벽파리)에서는 汽水域에서 주로 서식하는 망둥어科 어류들이 서식하고 있는 특징을 보였다. 우점종인 M.oxycephalus와 H.eigenmanni의 全長組成과 分布上 特異한 種인A.gracilis, A.rivularis, C.longicorpus의 生態와 측정치 등을 밝혔다. Distributional, morphological and ecological characters of the freshwater fishes were investigated at the seven stations in Jin-do on June and August, 1987. In this survey, 9 families, 24 enera and 30 species (totally 2753 individuals) were collected and indentified. Among them, Pseudorasbora parva, Hemiculter eigenmanni, Abottina rivularis, Aphyocypris chinensis, Acanthorodeus gracilis, Misgrurnus nizolepis were primary freshwater fishes, and Trachydermus fasciatus, Tridentiger obscurus, T. trigonocephalus, Acanthogobius elongata, A. hasta, A. lactipes, A. flavimanus, Acentrogobius pflaumi, Pseudogobius masago, Mugilogobius abei, Chaenogobius annularis, C. mororanus, Periphthalmus cantonensis, Fugu niphobles were pheripheral fishes. It was remarded in the view point of zoogeography of island freshwater fish of Korea that A. rivularis and A. gracilis were observed in the present studied areas for the first time. Two endemic species of C. longicorpus and A. gracilis were found in the present studied area and the former was belived to be the originally distributed species, however the latter might be considered secondary distributed species originated from elsewhere. The abundant species of this studied area were M. oxycephalus, O. latipes at st.1 and st.3, and H.eigenmanni, P. parva, C. auratus, A. rivularis at st. 4 and st. 7 and the gobiid fishes were at st.5 and st.6. The total length of M. oxycephalus and H. eigenmanni, the dominant species of present studied area, were measured and analyzed. Morphological and ecological characters of A. rivularis, A. gracilis and C. longicorpus which were the characteristic species of the distribution were compared with those species reported previously by others.

In this paper, reflex RGB data captured from WebCam is stored to HDD through USB port at every 5 seconds intervals. Also, if strangers are detected through Motion Detection routine, warning voice message is broadcasted and invasion message is transmitted by e-mail and transmit the e-mail title to mobile phone through WAP(Wireless Application Protocol) Push. The detected image is stored to hard-disk in 'month - day - hour - minute - second . jpg' data type. And the image data is transmitted to web server through FTP(File Transfer Protocol) because invader can deletes or destroys the image data on hard-disk. We implement a surveillance system which is able to utilize through internet regardless of time and space.

Cerebral angiography has been essential for the diagnosis of the intracranial aneurysms but. is sometimes accompanied by serious complications. Resolution of CT angiography was up-graded greatly to represent the three-demensional structure of vesseles since helical CT had been introduced. We have compared 26 cases of CT angiography and 28 cases of conventional angiography in terms of specificity and sensitivity for the diagnosis detectable aneurysm diameter. configurational diagnosis and diagnostic confidency. All results showed no statistical difference between CT angiography and conventional angiography. These should suggest that CT angiography could be replaced with conventional angiography for the diagnosis of ruptured aneurysms and even of unruptured aneurysms. resulting in the introduction of first screening modality of unruptured aneurysms.

Background: Dendritic cells (DCs) are rare leucocytes that are uniquely potent in their ability to capture, process and present antigens to T cells, and so selectively migrate through tissues to reach lymph nodes and spleen where initiation of immune responses takes place. It has been reported that a dense infilteration of dendritic cells correlates with a favorable prognosis in several types of cancer. A similar correlation also has been noted in patients with papillary carcinoma of thyroid. The purpose of this study is to determine whether DCs are generated from peripheral blood monocytes by using cytokines such as GM-CSF, TNF-α, and IL-4 and whether cytotoxic T cells activated by DCs attack the papillary carcinoma tissues. Methods: Peripheral blood was obtained from 2 patients with thyroid papillary cancer. DCs were established from monocytes by culturing in the presence of GM-CSF, Flt-3 ligand. TNF-α , and IL-4 for14 days. At day 14, expression of surface markers typical for DCs was analyzed morphologically. The immunophenotypic features of DCs such as CDla, CD83, and CD86 were analyzed by phase contrast microscopy. At day 15 DCs were incubated with thyroid cancer tissues and normal thyroid tissues for 7 days. Results: DCs were generated from the peripheral blood monocytes. The generated cells had the classic morphology of DCs. Activated cytotoxic T lymphocytes (CTLs) were observed. Veiled cell known as circulating DCs attached to the thyroid cancer tissues were observed. The CTLs activated by DCs were observed to attack the papillary carcinoma tissues by scanning electron microscope. However, normal tissues were not attacked by CTLs. Conclusion: DCs can be generated from the peripheral blood monocytes. Futhermore, the CTLs activated by DCs also can attack the papillary carcinoma tissues. These results that DCs can be used as adjuvants for adoptive immunotherapy of papillary thyroid cancer.

Authors report a case of one-stage transoral decompression and posterior fusion in rheumatoid atlantoaxial subluxation. A 63-year-old man developed a rheumatiod atlantoaxial subluxation with mild weakness of all extremities which developed relatively suddenly 3 months after the initial symptom of neck pain. Skeletal traction followed by transoral decompression and occipitocervical fusion was performed on the same day. Postoperative course has been uneventful and revealed favorable fusion state of occipito-atlanto-axis. The pertinent literature on theumatoid atlanto-axial subluxation is reviewed and discussed.

This study was performed to compare the cadmium accumulation levels in kidney with urinary cadmium excretion levels according to the duration of cadmium exposure in rats. Total 120 male rats, 6 weeks of age, were administered 0.5 mg/day of Cd to subcutaneously, intraperitoneally and orally 6 times per week for 12 weeks. The animals were sacrificed in the 1st day of 2nd, 4th, 6th, 8th, 10th and 12th week after beginning of cadmium administrations. Body weight, hematologic values, enzyme activities, renal Cd levels, urinary Cd and proteins were calculated and each value was compared according to the Cd administration routes. The Cd accumulation levels in the kidney of rats increased remarkably for 6-8th weeks which were experimented and urinary Cd excretion levels and urinary protein levels showed the tendency of increasing with the Cd accumulations in kidneys, especially in the subcutaneous injected rats. On the other hand, there was a significant positive correlation among the total Cd administration, the Cd accumulation in the kidneys, the urinary Cd excretion and protein.

The purpose of this study is to investigate the effect of the achievement motivation and self-efficacy on the performance of elementary school children. The subjects are 230 elementary school children(boy : 105, girl : 125) in K city. The independent variables of this study are achievement motivation and self-efficacy of subjects, and the dependent variables are golf putting. The results are as follows: 1.The level of achievement motivation is shown to have an effect on the performance of elementary school children: the subjects who have high achievement motivation show superior performance to those who have low score. 2.The level of self-efficacy is shown to have an effect on the performance of elementary school children: the subjects who have high self-efficacy show superior performance to those who have low score. 3.In the analysis of the change of post achievement motivation and self-efficacy due to success and failure, post achievement motivation is increased when subjects are confident to succeed it after performing, but reduced when subjects are afraid to fail their task. The post self-efficacy is increased when subjects think success to perform their task, but reduced when subjects think failure after their performance.

For the increase of treatment efficiency when waste water which included residual chlorine was biologically treated with activated sludge, elimination efficiency of COD and change of transmittance by activated sludge method were examined after the treatment of residual chlorine with ozone of 100 volt and l0ℓ-air/min., 0.8g-0_(3)/hr. in velocity. The results were as follows. 1) When the sample which included residual chlorine was treated with ozone of 0.8g-O_(3)/hr., COD removal rate by the change of pH and ozonization time was more efficient than acidity solution of pH 3.2(20%) and alkaline solution of pH 12.0(10%). Since the COD removal rate become 35% after 50 minutes of ozonization time at neutral solution of pH 7.2. 2) After the residual chlorine included sample was treated with ozone for 50 minutes to make the F/M rate of 0.1㎏·BOD/㎏·MLSS, the sample was reacted with activated sludge for 3, 6, 9 and 15 hours. The 6 hours reaction gave 85.8% COD elimination which showed higher efficiency than 60.5% by Na_(2)S_(2)O_(3) treatment togather with shorting efficiency of reaction time. 3) When such sample as polyphenol which gives dark brown color was treated with ozone for 50 minutes after being made into acidic, neutral and alkaline solution. the transmittance increased from 30- 40% to 70% and gave better result in alkaline solution.

Q fever is a zoonosis caused by Coxiella burnetii, Presenting as acute and chronic illness and it has been reported worldwide. Acute Q fever is usually asymptomatic or mild and self-limiting, but infective endocarditis is one of the most serious complications of chronic Q fever and can be fatal. Known risk factors for Q fever endocarditis are valvular heart disease, immunocompromised hosts, and pregnancy. There have been some reports on Q fever in Korea but there exists no report on Q fever endocarditis. We have experienced 2 cases of Q fever with underlying valvular heart disease; both Patients came to the hospital for evaluation of prolonged fever. Although Q fever and Q fever endocarditis are rare in Korea, Q fever endocarditis should be considered in the differential diagnosis of patient with infective endocarditis when causative microorganism cannot be identified.
