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.

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.

영국 1기 여성운동기 여성쟁점(Women's Issues)의 변천 연구

송태수 숙명여자대학교 아시아여성연구소 2005 아시아여성연구 Vol.44 No.1

본고는 영국 제1기 여성운동기 동안 여성쟁점(women's issues)의 형성 · 발전과정을 연구하고 있다. 산업화 과정에서 사회적 노동으로부터 축출되는 여성의 권리를 확보하기 위한 차원에서 증산층 여성이 주축이 되어 전개한 여성운동의 주요 쟁점은 여성의 노동권과 교육권 확대요구, 가족법과 여성재산권 문제, 성 관념의 변화와 도덕문제, 그리고 참정권 이슈 등을 포괄한다. 영국의 근대적 여성주의 쟁점의 형성 · 발전은 당시 사회 · 정치적 성격에 의해 독특한 양태로 진행되었다. 영국 제1기 여성운동기 여성쟁점(women's issues)의 형성· 발전과정의 특징은 다음과 같이 요약된다. 첫째, 빅토리아 시대 도덕적 엄숙주의 속에서도 성숙한 자유주의에 기반한 도덕적 합리성을 바탕으로 영국에서 여성쟁점의 대부분은 일찍이 1840년대부터 약 20여년 사이에 표출되었다. 둘째, 성숙한 자유주의라는 영국 정치의 특징은 여성쟁점의 형성과정에서도 그대로 반영되어 자유주의적 여성주의가 상당 기간 사회주의적 가치보다 우월적인 상태를 유지하였다. 셋째, 자유주의의 성숙 이외에도 의회주의 전통의 장구함은 여성쟁점 중 참정권운동에 역량의 집중이 가능하도록 하였으며, 그 방식에서도 이러한 전통은 유지되었다. This paper examines the process of formation & development of women's issues during the first phase of women's movement in England. The women's movement led by the middle class women strived to protect women's rights deprived during the exclusion from the social labor process as a result of the industrialization. The main issues of women's movement included expansion of rights to work and of education, the family law, the issues on women's property rights, the change of mind-set on sex and the issues on morality, and on the women suffrage etc. The articulation of the modern women's issues in England was characterized by the social and political factors. The characteristics of women's issues in England are summarized as follows: First, the majority of women's issues in England was expressed in about 20 years early from 1840's, based on moral rationality rooted in matrue liberalism though moral gravity of Victorian Era. Second, the characteristics of British politics called 'mature liberalism' were reflected in the process of articulating women's issues, so that the liberal position was a long while dominant over socialist position related to feminism. Third, the long tradition of parliamentarism, besides mature liberalism, enabled concentratiing dynamics of wome's movement on the issue of women suffrage.

This study was designed for evaluation of brainstem in schizophrenics with auditory hallucination. We investigated the BAEP on 14 schizophrenics with auditory hallucination 12 schizophrenics without auditory hallucination and 15 normal controls. The results were as follows; 1) Schizophrenics with auditory hallucination had a trend of more abnormal BAEP than schizophrenics without auditory hallucination(P〈0.06) 2) The severer auditory hallucination in schizophrenics was, the more frequent abnormal BAEP showed. 3) Schizophrenics with abnormal BAEP and with normal BAEP had no differences of age, sex, psychopathology, doses of neuroleptics, onset age and genetic loading. 4) In total schizophrenics, V amplitude was significantly lower and I/V amplitude ratio was significantly higher than in normal controls(P〈0.01). This findings suggest that schizophrenics with auditory hallucination may have brainstem dysfunction, which may induce auditory hallucination.

Estrogen is believed to decrease coronary artery disease. Protein kinase C-α(PKCα)appear to be important in signal conduction pathways. Estrogen treatment increases catalytic activity of PKCα,and activation of PKCαcan modulate estrogen receptor levels and responsiveness. And it was reported that activation of PKC can protect cells from apoptosis induced by Fas ligation. But the beneficial effect of estrogen on PKCαwas not clearly demonstrated. The objective of this study was to evaluate the role of PKCαafter ovariectomy and estrogen therapy in rat aorta. The results were summarized as below: 1. The significant pathological changes were not observed in the rat aorta irrelevant to ovariectomy and estrogen therapy. 2. The expression of Fas was decreased in the aorta of estrogen-treated rats than that of ovariectomized rats without estrogen therapy. 3. Increased expression of PKCαwas more marked in the aprta of estrogen-treated rats than that of ovariectomized rat without estrogen therapy. In conclusion,PKCαmay be important in signal conduation pathway on the effect of estrogen. Activation of PKCαby estrogen reduced Fas expression, suggesting that PKCαactivation may play a role in protection against atherasclerosis. Further studies are needed to elucidate the role of PKCαafter estrogen therapy.

Web-based analysis programs for reliability assessment of machine tools were developed in this study. First, the reliability data analysis program was developed to search for failure rate using failure data and reliability test data of mechanical part. Second, failure mode analysis was developed through performance tests like circular movement test vibration test for machine tools. This analysis program shows correlation between failure mode and performance test result. Third, tool life was predicted by correlation between flank wear and cutting time, using the extended Taylor tool life equation in turning data and the equivalently converted equation in order to apply ball endmill data to Taylor tool life equation in milling data. All the information related to input and result data can be stored in theses programs.

The development of software has a foundation for producing high-class software by evaluating and reflecting development fund and size correctly in the begining. There are many ways to evaluate size of software, but function point makes an accurate measurement by function ality, is used in many fields, and has excellent results in economic view. The main objective of this study is to seek for function point per man-month for develpment size and to apply funciton point as a project model to entrance examination systems of three universities and to compare the result with normal function point of US. Also we will expect development size evaluation nearly the same if we can reflect many chief cause in comparing program line count of COBOL by function point with program line count Written in COBOL. Hence function point can be used in formal contract between clients and producers software. Also. it can produce excellent project by consulting with clients if the terms desired changes or adds after initial consult.

To evaluate the specificity of restriction fragment length polymorphism (RFLP) of Newcastle disease virus (NDV) fusion (F) protein gene for various NDV strains. F protein genes of NDV CBP-1 isolate, LaSota, B1 and Kyojungwon (KJW) were amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and RFLP were examined. In RT-PCR using F primer sets for 1.7 kb F gene, the amplified products were observed in CBP-1, LaSota and B1 except KJW. However, F2 primer set for 521 bp yielded the amplified bands with all strains. The amplified F genes (1.7 kbp) were treatd with 15 different restriction enzymes to analyze RFLP and the cleavage patterns. CBP-1 showed various cleavage patterns with 8 enzymes, LaSota, with 11 enzymes and B1, with 11 enzymes. According to the cleavage patterns, the physical maps were constructed, and it was found that CBP-1, LaSota and B1 strains had specific cleavage sites with HinfI, XbaI and XhoI. These findings suggest that RFLP are worth applying in the diagnosis and molecular epidemiological studies of Newcastle disease.
