김용철,주영혁,윤석훤 정보통신정책학회 2005 정보통신정책연구 Vol.12 No.1

정보통신시장에서는 유무선통합, 통방융합 추세로 인해 다양한 혁신상품들이 출시되고 있다. 본 연구에서는 한 소비자가 갖고 있는 다양한 혁신상품의 수용의도를 파악하여, 특정 혁신상품의 수용의도에 다른 혁신상품의 수용의도가 미치는 영향을 파악하였다. 연구 결과, 통방융합 혁신상품의 수용의도에 유무선통합 혁신 상품의 수용의도가 영향을 미치는 것으로 나타났다. 이를 통해 혁신상품 목표고객 선정에 대한 전략적 시사점과 수용의도를 기반으로 한 소비자 혁신성 연구의 가능성이라는 이론적 시사점이 도출되었다. Recently, there have been so many innovative services introduced in information and communication market according to the development of ICT and the convergence of related industry. In this article, the authors examine the impact of adoptions of related innovative services on adoption of a innovative service in the view of adoption intention. Predictions are developed and tested using survey data(n=800) from professional marketing research firm. Result shows that adoption of each innovative service is significantly influenced by adoptions of other innovative services. This research has implication for targeting of innovative services strategically and measuring of consumer innovativeness practically.

The purpose of this study was to investigate the effects of exercise staining on MVO_2 and electrocardiogram QTc interval in obese woman and to propose the desirable method for weight loss. Subjects were fifteen obese women for this study. 8 subjects were prolonged QTc interval group and 7 subjects were normal QTc interval. They participated in exercise program consisted of aerobic exercise and weight training exercise at A Medical Center. The body composition including Boyd Weight, BMI, WHR and % Body Fat was measured. The resting and exercise(Bruce protocol 7th min) rate-pressure product(RPP) could be measured with HR and systolic BP for MVO_2 measurement. The electrocardiogram QTc interval was calculated with Bazzett's formula using automated software program. The measured data of this study were as follows: 1) After participating the exercise program consisted of aerobic exercise and weight training exercise, Body Weight, BMI, WHR and % Body Fat were significantly changed in two groups. (p<.05). 2. After participating in the exercise program consisted of aerobic exercise and weight training exercise, the resting and exercise MVO_2 using RPP were significantly changed in two groups(p<.05). 3) After participating in the exercise program consisted of aerobic exercise and weight training exercise, the electrocardiogram QTc interval were decreased but were not significantly changed in prolonged QTc interval group. (p<.29). However, it was significantly decreased in prolonged QTc interval(p<.00).

Developmental sequence of events of fore-limb in DDY mouse embryo were observed to obtain the data on shape ; on histology with special reference to the apical ectodermal ridge(AER), programmed cell death(PCD) and chondro-osteogenesis and ; on changes of glycoconjugates. Fore-limb buds appeared between the day 9.5 and 10 of gestation(plug day=0) and distal ends grew into paddle-like plates from day 11, plates condensed to form digital rays on day 12, webbed fingers on day 13 and fingers were separated on day 14. Well developed AER appeared with the beginning of elevation of buds and decreased in size from day 11 and remained remnants on day 12.5 of gestation. Proximal core mesenchyme began to condense form day 11 and transformed to precartilaginous zone 12 hours later chondrified from day 12.5 and ossified from day 15 and these phenomena proceeded proximo-distal sequence. Programmed cell death happened only between the day 10.5 to 11.5 and were confined to the proximal and middle zone of mesenchyme, which comes into question how PCD In motioned area and time correlate with subsequent morphogenses. PAS positive reactivity was gradually increased in the epithelium. AER and cartilaginous zone with the development proceed but that of mesenchyme was weak throughout the period. and in comparison with PAS reactivity, PAPS reactivity to the epithelium was always less but no difference in cartilaginous zone which suggest that amount and component of glycoeonjugates are variable and tissue/stage-specific in the developing limb.

뇌열환자에서 임상증상과 영상소견과의 관계 : Correlation of Clinical Outcome with Imaging Findings

Schizencephaly is an infrequent congenital disorder of neuronal migration characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the pial covering of the cortex. We have studied seven patients with schizencephaly rstrospectively to correlate clinical outcome with the type, size, and location of the clefts and to find associated brain anomalies. Three patients had bilateral clefts(one with two open lip clefts and the other two with a left open lip cleft and a right closed lip cleft), another two patients had left unilateral open lip clefts, and the rest two patients had right closed lip clefts. Clinically these patients presented motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Patients with bilateral clefts, paticularly open lip type had worse motor and developmental impairment than those with unilateral clefts. Patient with unilateral medium open lip cleft had worse motor and intellectual impairment than those with unilateral closed lip clefts or small open lip cleft. All patients with f개ntal lobe involvement had motor dysfunction. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. Three patients with skull changes such as enlargement of the hemicranium of erosion of the inner table of the skull were shunted but only one patient improved in the imaging study We conclude that the severity of patient's symptoms is related to the amount type and location of the involved brain.

This study suggests an improvement of building height regulation in urban area with a historic landmark, by an adoption of the observer-oriented building height regulation. A rigid-angle height regulation system that is current secures no pertinent perspective around the historic landmarks. Through a case study of 'Dong-dae Mun' with height calculations and 3D visual simulations, the observer-oriented building height regulation is proven to make more available space with less obstacles in the perspectives around historic landmark.

幼弱白鼠 肝細胞內 DNA, RNA 및 PAS 陽性物質에 미치는 Chlorambucil과 Ginseng Saponin의 相互作用에 關한 組織化學的 硏究

閔惠淑,全容赫,羅福瑛 고려대학교 의과대학 1982 고려대 의대 잡지 Vol.19 No.3

The effects of interaction between chlorambucil and crude ginseng extract (ginseng saponin) had teen investigated on liver cell of 90 experimental weanling albino rats from 22 healthy primiparous mother rats by means of histochemical detection as RNA, DNA and PAS positive materials 1. Severe regressive changes of the liver tissue, especially on the portal area, induced by intraperitoneal administration of single dose of chlorambucil rated 0.2㎎/0.1㏄ per 20㎎ of body weight had been protected or recovered from the degeneration by following administration of single dose of the crude ginseng extract rated 1.0㎎/0.1㏄ per 20㎎ of the body weight of young. 2. An abrupt declination of PAS positive material in hepatocyte due to use of chlorambucil was contrasted with a gradual inclination of it induced by use of crude ginseng extract, and the effect of the latter appears to be contributed for recovering the lower PAS reaction into that of the normal on the former hepatic cellular change. 3. A declination of stain property or RNA to Azure B was resulted from the use of chlorambucil, while that of DNA was not affected until 24 hours and later it was increased by 36 hours after the administration. 4. A slight decrease of the staining in both the DNA and RNA was recovered the property by 48 hours after the administration of crude ginseng extract. 5. On concomitant administration of both the chlorambucil and crude ginseng extract the staining property of the RNA to Azure B was shown a decrease in the initial stage, and was recovered in that of the normal immediately thereafter without influencing that for DNA.

음경의 Mondor씨 병 1례

김욱현,문기혁,송윤섭,박영호 순천향의학연구소 2004 Journal of Soonchunhyang Medical Science Vol.10 No.2

Superficial venous thrombosis of the chest wall was first described by Mondor in 1939. Braun-Falco reported in 1955 superficial penile vein involvement in diffuse thrombophlebitis of the abdominal wall and in 1958 Helm and Hodge first described isolated superficial dorsal penile vein thrombosis. Since then, fewer than 50 cases have been reported. The clinical presentation is usually redness and swelling of the dorsum of the penis, accompanied by a palpable, tender thrombotic vein. This acute and painful disease frightens the patients, who is concerned about his fertility and sexual function. The main cause of this disease is frequent sexual intercourse. Diagnosis is based upon anamnesis, physical examination and penile sonography with color Doppler imaging. It is usually a benign disease which resolves quickly under appropriate medical therapy. We present a man who was visited for this condition and was conservatively treated.
