Aqueous corrosion characteristics of low carbon steel with small amounts of Cr, Co, Cu, Ni and Ca, in synthetic groundwater was studied by electrochemical corrosion tests (potentiodynamic test and electrochemical impedance spectroscopy (EIS) measurements) and analytical techniques. Neither carbon steel nor newly alloyed steels showed passive behavior in this synthetic groundwater. Newly alloyed steels, containing Cr-Co, Cr-Cu-Ni and Cr-Cu-Ni-Ca showed higher corrosion resistance than carbon steel in the potentiodynamic tests. EIS measurements showed that the Nyquist plot presented two time constants. The high frequency resistance component (R_(rsut)) and low frequency resistance component (R_(et)) were affected by the alloying elements. The polarization resistance (RP= R_(et) +Ra) of steels could be clearly ranked as Cr-Cu-Ni-Ca steel >> Cr-Cu-Ni steel > Cr-Co steel > carbon steel. Results of surface analyses (XPS and EPMA) showed that Cr and Cu were concentrated in the inner region of rust. However, Co and Ni were uniformly distributed all over the rust layer. These alloying elements improved corrosion resistance of low alloy steel in synthetic groundwater. Especially, Cr-Cu-Ni-Ca steel had the lowest corrosion rate due to the inner rust film formation during the initial stage of corrosion, which suggested a potential for substituting carbon steel in soil environment (Received October 29, 2004)

홍주헌,윤광섭,최용희 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2004 한국식품저장유통학회지 Vol.11 No.1

η_(evap)분자량에 따라 다양한 생리활성을 나타내는 아가리쿠스버섯에서 분리한 조단백다당류를 고부가가치 기능성 소재로 개발하기 위하여 막분리 및 분무건조 공정에 따른 특성을 조사하였다. 아가리쿠스버섯 조단백다당류를 분자량 크기에 따라 여과하는 동안 공정온도에 따른 투과플럭스의 변화는 10 kDa와 150 kDa 모두에서 유사하였는데, 막분리 온도 및 압력이 증가함에 따라 비례적으로 증가하였으며,40℃에서의 투과플럭스가 가장 높았다. 시간에 따른 투과플럭스의 변화는 막분리 30분 경과시 급속히 감소하였으며, pore size가 10 kDadhk 150 kDa일 때 공정압력이 각각 1.2 kg_(f)/㎠ 와 2 kg_(f)/㎠에서 가장 높았다. 한외여과 후 아가리쿠스버섯 조단백다당류의 점도는 여과 전 13.9cP에서 여과후 10 kDa이하와 10∼150 kDa구간은 각각 10.8, 11.9cP로 점도가 저하되었으나, 150 kDa이상은 20.1cP로 점도가 증가되었다. 분자량 크기가 다른 3가지 분획물에 대한 분무건조 공정에서의 열효율성은 가열공기온도, 시료공급속도 및 농도가 증가할수록 열효율성이 증가함을 알 수 있었으며, 시료공급속도가 가장 중요한 영향인자임을 확인하였다. This study was conducted to investigate the characteristics of ultrafiltration and spray drying process for crude protein bound polysaccharide(CPBP) isolated from Agaricus blasei Murill. In ultrafiltraion process, the permeate flux increased with the increase of operating pressure and temperature. The permeate flux declined continuously while the fouling materials were accumulated on the membrane as the operation time increased. In comparing of raw CPBP and filtered CPBP, the viscosity of CPBP treated UF was decreased and AE value of treated samples was increased. Thermal efficiencies of spray drying process were increased by increasing inlet temperature, feed rate and feed concentration.

For one month from September 24, 1992, the knowledge, attitude and experience toward sex of K University student were investigated, and the results were as follows. 1. The time that majority of subjects began to be interested in sex was at the 5th to 6th grade of primary school (22.8%). The case that had troubles about sex was 77.9% of all subjects and this reveals that sex is an important issue of adolescent period. The method to resolve their sexual desire were reading books (12.2%), masturbation (10.2%) and suppression (10%). They got information of sex from magazines (37.4%), friends (21.6%) and they counselled the issue of sex with their friends (65.6%). 2. Almost all of the subjects (98.3%) talked about marriage and love at school and were interested in making friends of opposite sex. 88.4% of subjects had an experience of having friends of opposite sex and 45.3% of subjects thought them as friends. 78.1% of parents were affirmative to their children´s making friends with opposite sex. 3. Only 35.6% of subjects thought that pre-marriage virginity should be kept, and there was difference of concept between males (28.3%) and females (50.6%) (p<0.001). 4. The experience of msturbation was 63.5% and there was large difference between both sexes (male: 88.4%, female: 12.8%). The subjects that had not experienced kiss were 50.4% of total. The subjects that had not experienced sexual intercourse were 68.3% of total, and there were statistically significant difference between both sexes(male: 56.3%, female: 93%).

인공 해수분위기에서 저탄소강의 부식특성에 미치는 합금원소 Cr, Co 및 W의 효과

심재주,유승재,최윤석,김정구,유장용 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.12

The aqueous corrosion characteristics of 1% Cr-steel alloyed with small amounts of Co and W, in synthetic seawater was studied by using immersion weight-loss tests, electrochemical corrosion tests (potentiodynamic test and electrochemical impedance spectroscopy (EIS) measurements) and analytical techniques. 1% Cr steels containing Co or W from 0.2 to 0.4 wt.% showed higher corrosion resistance than the 1% Cr steel in the immersion and potentiodynamic tests. EIS measurements showed that the Nyquist plot presented one time constant. Furthermore, the Co- and W-bearing steels present higher Rp values than the 1% Cr steel through all the test period. The better corrosion resistance of the Co-and W-bearing steels is attributed to protectiveness of the surface layer. The corrosion products were examined using electron probe microanalysis (EPMA) and X-ray photoelectron spectroscopy (XPS). The results of EPMA indicated that Cr was concentrated in the inner region of the rust layer, while Co and W were distributed all over the rust layer. XPS results showed that Co existed as a trivalent oxide in the rust layer and W in the rust appeared in the form of a WO₄ compound.

The aim of this study is to report 2 cases of acute promyelocytic leukemia who died from intracranial hemorrhage following leukapheresis and to provide proper preventive measures against hemorrhage following leukapheresis. From 1994 to 1997, a total of twenty-six patients with leukemia underwent leukapheresis to control hyperleukocytosis at Ajou University Hospital. Two patients with acute promyelocytic leukemia received all-trans retinoic acid but developed drug-induced hyperleukocytosis. Shortly after leukapheresis, they died from intracranial hemorrhage. The risk factors for fatal hemorrhage are thought to be coexisting disseminated intravascular coagulation(DIC), thrombocytopenia aggravated by leukapheresis, exacerbated coagulopathy related to mechanical trauma through leukapheresis and the excess use of citrate during leukapheresis. To reduce the risk of the bleeding associated with leukapheresis, it is necessary to replace platelet sufficiently before and after leukapheresis and to give calcium to correct coagulopathy induced by excess citrate which is used as anticoagulant as well as the correction of disseminated intravascular coagulation.

인공 수돗물 분위기에서 저탄소강의 부식특성에 미치는 합금원소(Cr, Co, W, Cu, Ni, Ca)의 영향에 관한 연구

심재주,최윤석,김정구 대한금속재료학회 2003 대한금속·재료학회지 Vol.41 No.9

This paper presents the corrosion behavior of the low alloy steel contained alloying elements such as Cr, Co, W, Cu, Ni and Ca in synthetic tap water using potentiodynamic polarization tests, electrochemical impedance spectroscopy (EIS), XPS and EPMA. Potentiodynamic poalrization curves indicated that all the specimens had active corrosion behavior. Corrosion rate tended to reduce as the result of the alloying. Also, EIS test results showed that the more the content of element, the larger the polarization resistance. It can be seen that these results were caused from the formation of a coherent, protective film contained alloying elements. Actually, XPS results showed that Cr, Cu, and Ca were formed as protective metal oxides at the surface of rust film under the stagnant condition. The results of EPMA indicated that Cr, Cu, and Ca were distributed densely at the inner layer of the rust film, while Co, W, and Ni were distributed at the whole layer under the flow condition. Consequently, alloying elements improved corrosion resistance of low alloy steel in synthetic tap water. Especially, Cr, Cu, Ni, and Ca-containing specimen had the lowest corrosion rate due to the inner rust film formation during the initial stage of corrosion, which suggested a potential substitute for carbon steel in potable water system.
