본 연구는 선행연구에서 조사된 핸드폰의 고객요구속성을 Kano 모델의 품질특성에 적용하여 시간의 흐름에 따라 어떤 변화가 있는지를 살펴보고자 한다. 또한 고객들의 새로운 요구속성이 나타났는지도 함께 살펴보고자 한다. 많은 문헌과 선행연구에서 나타나고 있는 시간에 따른 품질특성의 이동이 매력적 품질에서 일원적 품질로 일원적 품질에서 당연적 품질로 변화하는 진부화(陳腐化)현상이 나타나는지도 함께 살펴보고자 한다. In this study, previous research (Sung-Uk Lim, 2004) surveyed in customer demand for mobile phones the quality characteristics of properties applied to the Kano model, the flow of time, depending on whether any changes will be discussed. In addition, our customers" new requirements will be examined along with the property map appeared. The movement of time-dependent quality characteristics appeared in many previous studies Obsolescence Phenomenon - from Attactive Quality Element to One-Dimensional Quality Element, from One-Dimensional Quality Element to Must-Be Quality Element - may appear be examined together.

임성철,이용,김동출,강길,변익건,박정희,최석민 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.2

CD24 is a small heavily glycosylated glycosylphosphatidylinosito-linked cell surface protein, which is expressed in hematologic malignancies as well as in a large variety of solid tumors, It appears to function as a ligand of PUselectin, an adhesion molecule that is present in activated platelets and endothelial cells. The authors aimed to evaluate CD24 protein expression in adenoma and adenocarcinoma of gallbladder to correlate to clinicopathologic data. The staining- was evaluated as stainability (negative, weak-, moderate-, strong-positive) and staining' patterns (membranous vs. intracytoplasmic) for statistical analysis. A highly significant association of cytoplasmic CD24 expression with adenocarcinoma compared to the adenoma of gallbladder was demonstrated. The present study demonstrates that CD24 was abundantly expressed on adenocarcinoma rather than on adenoma, but it was not statistically significant, Interrelation between the stainability or intracytoplasmic staining of CD24 and lymph node metastasis was not statistically significant. The authors conclude that CD24 is involved in tumorigenesis of gallbladder mucosa and intracytoplasmic expression of CD24 is an important molecular marker for malignant transformation.

12-O-Tetradecanoylphorbol-13-Acetate에 의한 HL-60 세포 분화유도중 Vimentin 유전자 전사조절에 대한 AP-1의 역할

Purpose: To gain insight on the role of AP-1 in transcriptional regulation of vimentin gene during differentiation of HL-60 cells by 12-O-tetradecanoylphorbol-13-acetate (TPA), the levels of vimentin mRNA and AP-1 have been investigated with Northern blot hybridization and DNA mobility shift assay. Materials and Methods: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal calf serum and antibiotics in a humidified 5% CO_2 at 37℃. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe(Upper strand, 5'-CGCTTGATGAGTCAGCCG- 3') for AP-1 binding activity was mixed with nuclear extracts in a 20 μl reaction volume containing 300 mM KCI, 60 mM HEPES, pH 7.9, 25 mM MgCI_2, 1 mM EDTA, 1 mM DTT, 60% glycerol, and 2 ㎍ of poly[dI-dC]. Results: TPA increased vimentin mRNA levels, with maximal stimulation reached at 24 hr. The level of vimentin mRNA was induced in proportion to the concentration of TPA. TPA-induced vimentin mRNA was almost reduced by actinomycin-D pretreatment. TPA-induced stimulation of vimentin gene was completely reduced by staurosporin pretreatment. In DNA mobility shift assay, AP-1 newly appeared at 24 hr during TPA-induced differentiation and was almost not detected after the pretreatment of staurosporin. Conclusions: These results suggest that the induction of vimentin mRNA during TPA-dependent differentiation in HL-60 cells may be mediated by protein kinases C signal transduction and AP-1 is important to transcriptional regulation.

방사선 센서의 동작특성

임영화,한상효,김도성,강희동 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1

A Geiger-M□ller(GM) radiation sensor is fabricated by using the vacuum system and gas feeding system. The base pressure of the vacuum system is 1X10^(-7)torr, and two MFCs(0~10sccm, ±1% accuracy of the full scale) are used to control the composition of filling gas exactly. The fabricated GM radiation sensor is simultaneously filled with the mixture of neon and clorine. The mica window(7.43mg/cm^(2)) is attached to the GM radiation sensor. The optimized GM radiation sensor has about 660V starting voltage, 125V plateua length, and 10%/100V plateau slope.

임상현,유진홍,권순석,김연식,신완식,강문원,정명희 대한화학요법학회 1997 대한화학요법학회지 Vol.15 No.2

최근 저자들은 viridans streptococcus에 의한 인후농약으로 인하여 발생한 종격동염 및 농흉을 보인 47세 여자 환자를 적절한 배농과 항생제로 치료한 국내 최초의 1예를 치험하였기에 문헌 고찰과 함께 보고하는 바이다. Since the antibiotic era, retropharyngeal abscess became a rare disease entity nowadays. But it may often progress to lethal complications involving vital structure if diagnosis or treatment is delayed. We experienced a case of empyema and mediastinitis complicating retropharyngeal abscess caused by viridans streptococcus in a 47-year-old female patient with diabetes mellitus. She was successfully treated with appropriate antibiotic therapy combined with percutaneous abscess drainage. To our knowledge, such a complication of retropharyngeal abscess has not been reported in Korea yet and we present this unusual case herein followed by a review of the related literature.

폐가스에서 황화수소 제거를 위한 바이오필터/광촉매반응기 시스템의 활용

임광희,박상원 한국공업화학회 2005 응용화학 Vol.9 No.1

Transient behavior of biofilter/photo-catalytic reactor system was observed to eliminate hydrogen sulfide from waste air at its four sampling ports. The biofilter was packed with a eqivolume mixture of granular activated carbon(GAC) and compost as packing media on which Thiobacillus sp. IW was inoculated and was fixed. The biofilter/photo-catalytic reactor system was run for eight stages of operation under various operating conditions. As a result the removal efficiency began to decrease from 100% after the inlet load of hydrogen sulfide surpassed ca. 100 S-g/㎥/h and was finally continued at 60%. The maximum elimination capacity of biofilter/photo-catalytic reactor system was ca. 130 S-g/㎥/h.
