철계 소결부품의 사출성형에 관한 연구

김영홍,권영순,김환태,김충식 울산대학교 1994 공학연구논문집 Vol.25 No.2

P가 첨가된 미세한 Fe 분말을 사용하여 Fe 및 Fe-Mo-Ni계에 대해 금속사출 성형방법에 의한 소결부품의 제조 가능성에 대해 조사한 결과, 바닝더로 사용한 Methylcellulos의 부피분율이 11vol%, 용매인 뭉의 양이 12wt%일때 우수한 성형성 및 소결특성을 보였다. 사출성형 조건은 다이의 예열온도가 110℃, 다이내의 유지시간이 3분일때 우수한 성형성을 보였으며, 650℃의 온도에서 1시간 유지하였을때 바인더는 완전히 제거되었다. Fe계 사출성형체의 소결시 얻어진 소결밀도는 이론밀도의 90%였으며, 활성제인 P가 소량 첨가됨으로써 소결성이 개선되어 95%정도의 소결밀도를 나타내었다. Using fine powders, the possiblity for the Metal Injection Moulding of the Fe and Fe-Mo-Ni steel with addition phosphours was investigated. The experimental results were obtained as follow; 1. The relative good molding and sintering behavior were obtained by using the binder constituted of 11 vol% methylcellulose and 12w% water solvent. 2. The preheated mould temperature and residence time were 110℃ and 240 sec for the optimal moulding condition. The binder could be fully removed by debinding at 650℃ for 1 hour. 3. The injection moulded Fe-parts could be obtained the relative sintered density about 90%. By addition of the small amount of phosphorus the more densification and then the relative sintered density could be obtained about 95%.

New technology has always carried two faces, which are the opportunity and the crisis. Intranet, recently appeared in the computing world, is being accepted as a replacement of traditional Client/Server technology. Since intranet has not been completely built even in its concept, it will give a company the crisis rather than the opportunity. To take the new opportunity for a business and organizational innovation through the intranet, its builder should necessarily acquire the knowledge of the preliminary considerations to the building. The purposes of this article are to define the concept of intranet, to investigate the cases and the building methodologies, and to discuss the preliminary considerations to the building.

이충원,이종영,박종원,윤능기,김영조,이현우,이무식,서석권 啓明大學校 醫科大學 1993 계명의대학술지 Vol.12 No.3

1991년3월부터 8월사이에 대구시에 소재한 1개의 대학병원의 종합검진센타에 내원해서 종합검진을 받은 남자 422명(69.9%)과 여자 182명(30.1%)을 대상으로 하여 심헐관계질환의 위험요인들의 전체적인 분포를 보았다. 평균 연령은 남자가 43.3(표준편차, 10.3), 여자가 44.4(표준편차, 10.8)였다. 남자에서 연령에 따라 0.05 수준에서 통계적인 유의성을 보인 위험인자는 혈청 총콜레스테롤(TC). 트리글리세라이드(TC), 고밀도 지단백콜레스테롤(HDL), 저밀도 지단백콜레스테롤(LDL), 수축기혈압, 비체중, A형행동양상이었으며 생활습관으로서는 음주, 흡연, 규칙적인 운동, 우유와 커피섭취, 수면 등이었다. 여자에서는 TC, TG, LDL, 수축기와 확장기혈압, 비체중 그리고 커피섭취와 수면 등이었다. 남자에서 총콜레스테롤의 평균은 181.7mg/dl(표준편차, 32.2), 여자는 182.5mg/이(표준편차, 42.2)였다. 대부분의 위험인자들은 구미의 수준에 미치지 못했으나 남자에서 흡연율이 전체적으로 61.8%로 높으 수준이었으며 특히, 20~29세가 72.9%, 30~39세가 75.2%로서 다른 연령군에 비해 상대적으로 높았다. 여자에서는 전체적으로 6.0%에 지나지 않았다. 확장기혈압 90mmHg 이상을 고혈압자로 정의했을 때의 유병률이 여자 전체대상자에서 24.7%로 높았으며 50-59세는 표본수가 적어서 문제가 되었으나 53.1%였다. 어떤 인구집단내에서 총콜레스테롤의 평균이 200mg/dl 미만이면 고혈압과 흡연의 인구집단의 수준에 관계없이 관상동맥질환(coronary heart disease)의 발생은 드문 것으로 보고가 되고 있으므로 당분간 관상동맥질환 발생률의 급속한 절대적인 증가는 힘드리라 사료된다. 그러나 이러한 결과는 본 연구의 대상자들이 대표성을 지니지 못하며 건강검진센터에 자발적으로 내원한 사람들이므로 해석에 주의를 요한다. Authors examined the distributions of the risk factors for the coronary heart disease in the 422 male (69.9%) and 182 female (30.1%) visitors to the health examination center of a university hospital located in Taegu March to August 1991. Mean age of males was 43.3(standard deviation, SD 10.3) and that of females was 44.4(SD 10.8). Total cholesterol(TC), triglyceride (TG), high-density lipoprotein and low-density lipoprotein cholesterol(LDL), systolic blood pressure, Quetelet index, and Type A Behavior Pattern, and some of life habit variables(alcohol intake, smoking, regular exercise, milk and coffee intake and sleeping) were statistically significant in age groups of the males(P<0.05). In the females, TC, TG and LDL, systolic and diastolic pressure, Quetelet index, coffee intake and sleeping were statistically significant in age groups (P<0.05). Mean of total cholesterol was 181.7㎎/dl(SD,32.2) in males and that of females was 182.5㎎/dl(SD,42.2). Most of the risk factors levels were lower than the Euro-Americans', while smokers were high with 61.8%, especially 72.9% in 20-29 age group and 75.2% in 30-39 age group in males. In females, smokers were just 6.0%. Hypertensives defined by more than 90mmHg diastolic pressure were 24.7% in females, particularly 53.1% in 50-59 age group, but size of the strata was rather small(N=49). In the light of the report that coronary heart disease is uncommon irrespective of population levels of smoking and hypertension, where average total blood cholesterol level in a population is low(<200mg/dl), it is not likely that the absolute increase of the number of the coronary heart disease will increase markedly in the near future. But cautions should be exercised in interpreting the results of this study due to the lack of representativeness and volunteerism. .

전신성 홍반성 루프스에서 고용량 경정맥 당질코르티이드로 치료된 단백질 소실성 장질환 1예

Generalizes edema and hypoalbuminemia are relatively common presenting manifestations in many clinical situations. The differential diagnosis of hypoalbuminemia include; Kwashiorkor, synthetic dysfunction of the liver, and excessive protein loss as in nephrotic syndrome. In systemic lupus erythematosus (SLE), hypoalbuminemia and generalized edema are most commonly due to protein loss associated with lupus nephritis; gastrointestinal involvement is uncommon, and therefore protein loss through the gastrointestinal tract is quite rare. We report a case of a protein losing enteropathy (PLE) associated with SLE. The patient was referred to out hospital for generalized edema, arthralgia and facial rash. After clinical evaluation, the patient met the criteria for the SLE diagnosis; hypoalbuminemia with general edema was consistent with a protein losing enteropathy. After two weeks of therapy with parenteral high dose glucocorticoid, the patients was improved in laboratory findings as well as clinical symptoms.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

<P>Achieving high sensitivity in solid-state gas sensors can allow the precise detection of chemical agents. In particular, detection of volatile organic compounds (VOCs) at the parts per billion (ppb) level is critical for the early diagnosis of diseases. To obtain high sensitivity, two requirements need to be simultaneously satisfied: (i) low electrical noise and (ii) strong signal, which existing sensor materials cannot meet. Here, we demonstrate that 2D metal carbide MXenes, which possess high metallic conductivity for low noise and a fully functionalized surface for a strong signal, greatly outperform the sensitivity of conventional semiconductor channel materials. Ti<SUB>3</SUB>C<SUB>2</SUB>T<SUB><I>x</I></SUB> MXene gas sensors exhibited a very low limit of detection of 50–100 ppb for VOC gases at room temperature. Also, the extremely low noise led to a signal-to-noise ratio 2 orders of magnitude higher than that of other 2D materials, surpassing the best sensors known. Our results provide insight in utilizing highly functionalized metallic sensing channels for developing highly sensitive sensors.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2018/ancac3.2018.12.issue-2/acsnano.7b07460/production/images/medium/nn-2017-07460z_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn7b07460'>ACS Electronic Supporting Info</A></P>
