In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

저자들은 중증 재생불량성빈혈로 동종 골수이식 및 추가적인 동종 말초혈액 조혈모세포이식을 시행 받은 후 만성 이식편대숙주질환이 발생하여 면역억제제로 조절되었으나 자가면역성 갑상선기능항진증이 병발한 1예를 경험하였기에 이를 보고하는 바이다. Chronic graft-versus-host disease (GVHD), which is a frequent complication following bone marrow transplantation (BMT), is characterized by fibrosis of the skin, liver, lungs, and gastrointestinal tract, immunodeficiency, and the production of autoantibodies. Endocrine dysfunction, in particular thyroid disease, has been described following BMT, but this has previously meant hypothyroidism secondary to total body irradiation or transfer of autoimmune hyperthyroidism from a donor with Graves’ disease rather than in association with chronic GVHD. We report a case of a 26-year-old man who developed Graves’ disease eight years after BMT and who had remission of chronic GVHD. He received an allogeneic BMT for severe aplastic anemia. Eighteen months after BMT, diarrhea and chronic GVHD developed and were treated with cyclosporine and steroid. Four years after ceasing the cyclosporine, the patient developed weight loss, palpitations, fever, and anterior neck swelling, and was diagnosed with Graves’ disease based on typical thyroid function tests. The signs and symptoms in the patient improved with propylthiouracil and propranolol.

A Decision Model for Advertising Expense: From the Perspective of the Blockholder's Private Benefits

Hwang,Joon-Ho,Chun,Se-Hak 한국상품학회 2009 商品學硏究 Vol.27 No.2

This paper examines how the size of private benefits of large owners, measured using block premium, affects changes in advertising expense of the company. If large owners enjoy private benefits through engaging in pet projects, it will result in increased advertising expense. On a sample of 130 firms whose blocks of shares are traded in the U.S., we show that the magnitude of private benefits is not associated with changes in advertising expense.

Feather waste, generated in large quantities as a byproduct of commercial poultry processing, is almost pure keratin, which is not easily degradable by common proteolytic enzymes. Several feather-degrading bacterial isolates were isolated from feather waste and soil. These isolates were able to degrade chicken feather, when grown on basal medium containing 1.0% native feather as a source of energy, carbon, and nitrogen. The isolates were characterized according to morphological characteristics and biochemical tests, and Vitek and API kit system. belonging to the Acinetobacter calcoaceticus complex, Bacillus thuringiensis, Bacillus circulans, Bacillus cereus. It was observed that aerobic growth by the isolate on single whole chicken feather, resulted in complete degradation of the keratin protein after 5-6 days of incubation at 37℃. The production of protein by the organism was decreased with cultivation time, with the maximum activity coinciding with the start of the stationary phase. The kerationolytic activity increased with cultivation time.

Purpose of this research is estimating polymerization depth of different source of light. XL 3000 for halogen light, Apollo 95E for plasma arc light and Easy cure for LED light source were used in this study. Different shade (B1 & A3) resin composites (Esthet-X, Dentsply, U.S.A.) were used to measure depth of cure. 1, 2, and 3 mm thick samples were light cured for three seconds, six seconds or 10 seconds with Apollo 95E and they were light cured with XL-3000 and Easy cure for 10 seconds, 20 seconds, or 40 seconds. Vicker's hardness test carried out after store samples for 24 hours in distilled water. Results were as following. 1. Curing time increases from all source of lights. curing depth increased(p<0.05). 2. Depth (that except 1mm group and 2mm group which lighten to halogen source of light) deepens in all groups, Vicker's hardness decreased(p<0.05). 3. Vicker's hardness of A3 shade composite was lower in all depths more than B1 shade composites in group that do polymerization for 10 seconds and 20 seconds using halogen source of light(p<0.05), but group that do polymerization for 40 seconds did not show difference(p>0.05). 4. Groups that do polymerization using Plasma arc and LED source of light did not show Vicker's hardness difference according to color at surface and 1mm depth(p>0.05), but showed difference according to color at 2mm and 3mm depth(p<0.05). The results showed that Apollo 95E need more polymerization times than manufacturer's recommendation (3 seconds), and Easy cure need polymerization time of XL-3000 at least.

이승준,황호정 중앙대학교 기술과학연구소 2002 기술과학연구소 논문집 Vol.32 No.-

AC PDP에서 사용하는 가스의 혼합비, 압력 페닝 효과를 고려한 가스 조합의 최적화를 통해 낮은 방전전압으로 휘도의 증가를 얻을 수 있는 고휘도, 고효율 PDP 페닝 기체 혼합비를 찾고자 하였다. He(70%)-Ne(27%)-Xe(3%)의 3원 혼합기체와 Ne(96%)-Xe(4%)의 2원 혼합기체에 페닝 효과를 극대화하기 위한 소량의 Ar, Kr을 첨가하여 각각의 첨가비에 따른 방전 개시전압, 방전 유지저압, 휘도, 발광효율등을 측정하였다. 또한 페닝효과에 의한 방전 공간상의 전자수 증가를 확인하기 위해 셀 내의 전극 위에 쌓이는 벽전하 양을 측정하였다. 소량의 Ar(0.01%-0.03%) 또는 Kr(0.01%-0.03%)을 He-Ne-Xe과 Ne-Xe 혼합가스에 참가했을 때 페닝효과에 기인하여 휘도 및 발광효율이 각각 최고 10%-20% 증가하였다. We suggest a new penning gas mixture, in order to find the optimum mixture gas in plasma display panel. The optimum gas composition has been found by the partial pressure of inert gases (such as Ar and Kr added to matrix of He(70%)-Ne(27%)-Xe(3%) and Ne(96%)-Xe(4%). The influences of Ar of Kr addition to Ne(96%)-XE(4%) and He(70%)-Ne(27%)-Xe(3%) mixture gases are experimentally investigated for AC Plasma Display Panel. When rare Ar(0.01%-0.03%) or Kr(0.01%-0.03%) is added Ne-Xe and He-Ne-Xe mixture gases, the luminance increases over 10%-20% and luminous efficiency increases over 10-20% at 200Torr. It is sure that luminance and efficiency are improved by Penning effec.
