임상적으로 악성메라닌 세포종 ( 흑색종 ) 에 유사한 중결성 색소성 기저세포 (基底細胞) 표피 ( Basal - Cell Epithelioma ) 의 1증례
임철완 대한피부과학회 1978 大韓皮膚科學會誌 Vol.16 No.1
A thirty-seven-year old, man was affected a skin lesion of dark pigmented, raised, easy to bleed on touching the crust and indurated tumor with moderate hard consistency and the tumor was located over the nasolabial fold of right side, which was alike to malignant melanoma clinically. the tumor was oval-shaped and measured 0.8cm*1.3cm in diameter, which did not make any pain or itching sensation. It started with small papule about 4 years ago which gradually increased in size and ulcerated with occasional bleeding. His skin lesion was treated with topical agent at drug store, however, it was not effective. In this hospital, the patient received the skin biopsy of the tumor and the diagnosis was established as solid basal cell epithelioma histopathclgically. and the tumor was removed by surgical technique and the result was satisfactory without recurrence until upto date follw-up observation (for four years and seven months). On the conclusion, authors presented a case of solid pigmented vasal cell epithelioma resmbling malignant melignant melanoma with histopathological study and treated with surgical management and obtained very satisfying result.
제 3형 과비질단백혈증 ( TypeⅢ Hyperlipoproteinimia ) 의 1증례보고와 원발성과비질단백혈증의 문헌고찰
김영표,임철완 대한피부과학회 1974 大韓皮膚科學會誌 Vol.12 No.4
A stout and obese fourty five year-old Korean man was affected with hyperlipoproteinemia type III. His skin lesion showed yellowish papular eruptive xanthomas with erythematous halo located chiefly on the trunk and extensor aspects of the extremities including both palms. In addition to the skin lesion he showed pea-sized cervical lymphnode swellings, slightly tessellated fundi and, on ECG, premature ventricular contraction. Otherwise no specific findings were seen. The laboratory examinations showed increases of both serum cholesterol and triglycerides, increased fasting blood sugar level and abnormal glucose tolerance curve with turbid color of fasting blood serum which had been kept standing at 4C for 24 hours. On the paper electrophoresis $quot;broad beta band$quot; blending with the pre-beta area was noted. The authors discussed laboratory characteristics, clinical manifestations and differential diagnosis of primary hyperlipoproteinemia on each type with review of the literatures of the disease.
Syntax-phonology Interface - Linearization in English RNR Construction*
Ihm IckHee 한국영어학학회 2007 영어학연구 Vol.- No.24
This paper argues that ‘Mid?way conjunction(Park (2005a)) and coordination by conjoin?α operation (Ihm(2007))’ approach is on the right track for accounting for the derivation of Right Node Raising construction. This paper also deals with the linearization process of the English RNR construction. Sabagh(2003) assumes that the linearization of Right Node Raising construction proceeds in a step-by-step fashion (Spell-Out) and consistency is preserved between the ordering statements that have already been established and new ordering statements. However, his argument doesn’t maintain consistency in the part of the complex RNR construction. As an alternative, this paper explains the linearization process of English RNR construction through ‘Mid?way conjunction and coordination approach(Park (2005a) plus conjoin?α operation(Ihm (2007)) and Linear Correspondence Axiom’.
Effect of Reaction Conditions and Catalytic Properties on Methanol Conversion over SAPO-34
Ihm, Son Ki,Park, Young Kwon,Baek, Se Won 한국공업화학회 2001 Journal of Industrial and Engineering Chemistry Vol.7 No.3
Methanol conversion was carried out over SAPO-34 catalysts at 400℃ and 1 atm to investigate the selectivity of the hydrocarbon products. SAPO-34 catalysts with different Si/Al ratios were modified by (hydro)thermal treatments, ammonia preadsorption, and/or TEOS CVD to change their catalytic properties. The change in acidity induced by these treatments did not seem to produce any significant changes in activity and selectivity, however the reaction parameters, including the partial pressure of methanol and presence of water in the feed, were found to influence the hydrocarbon product distribution by increasing the C₂ (especially ethene) selectivity.

서 론 : 여러 인자들이 interleukin-6(IL-6)의 발현을조절한다. 면역복합체와 앤지오텐신 II(AII)는 사구체신염의 발달에 관여할 것으로 알려져 있다. 따라서 면역응집물과 AII가 메산지움 세포의 IL-6 발현에 미치는 영향과 이에 대한 losartan(AII 수용체 제 1형 길항제)또는 hydrocortisone의 억제 여부를 알아보았다. 방 법 : 배양된 인체 메산지움 세포에 IgG 또는 IgA면역응집물(100 μg/mL) 및 AII(10^(-7) M)를 투여하였으며, 또한 면역응집물에 hydrocortisone(0.5 μg/mL) 또는 losartan(10-6 M)을 첨가하였다. 48시간 후에 메산지움 세포의 IL-6 mRNA의 발현을 reverse transcription-polymerase chain reaction 방법으로 측정하였다. 결 과 : 메산지움 세포의 IgG 또는 IgA 면역응집물및 AII에 의한 IL-6 mRNA 발현 : IgG 또는 IgA 면역응집물(100 μg/mL) 및 AII(10^(-7) M)는 메산지움 세포의 β-actin에 대한 IL-6의 mRNA 생산물비를 의미있게 증가시켰다. Hydrocortisone 또는 losartan의 IgG또는 IgA 면역응집물에 의한 IL-6 mRNA 발현의 조절 여부 : hydrocortisone(0.5 μg/mL)의 첨가는 IgA 면역응집물에 의한 IL-6 mRNA 발현 증가를 감소시켰으며 losartan(10-6 M) 투여는 IgG 면역응집물에 의한IL-6 mRNA 발현 증가를 감소시켰다. 결 론 : IgG 또는 IgA 면역응집물 및 AII는 메산지움 세포의 IL-6의 mRNA 발현을 증가시킴을 알 수 있었으며, 이로써 사구체신염에서의 메산지움 병변의 발달에 관여할 것으로 추정되었다. Purpose : Various factors regulate interleukin(IL)-6 expression in mesangial cells (MCs). Immune complexes or angiotensin II(AII) are involved in the development of glomerulonephritis(GN). We evaluated the effects of IgG and IgA aggregates or AII on IL-6 mRNA expression in human MCs and the modulation by losartan, an AT1 receptor blocker, or hydrocortisone. Methods : After 48 hours of culture in the presence of sera, IL-6 mRNA expression was analyzed by reverse transcription and polymerase chain reaction(PCR). Results : Incubation of MCs with IgA or IgG aggregates(100 μg/mL) as well as AII(10^(-7) M) enhanced the ratio of PCR products for IL-6 to β-actin on densitometric results. The addition of hydrocortisone(0.5 μg/mL) reduced the IgA aggregates-induced IL-6 mRNA expression and losartan(10-6 M) reduced IgG aggregates- induced IL-6 mRNA expression. Conclusion : These results suggest that IgG and IgA aggregates and AII may induce IL-6 expression in GN which can be partially suppressed by hydrocortisone or AT1 receptor blocker.

Analysis of Traffic Accident using Association Rule Model
Ihm, Sun-Young,Park, Young-Ho Korea Multimedia Society 2018 The journal of multimedia information system Vol.5 No.2
Traffic accident analysis is important to reduce the occurrence of the accidents. In this paper, we analyze the traffic accident with Apriori algorithm to find out an association rule of traffic accident in Korea. We first design the traffic accident analysis model, and then collect the traffic accidents data. We preprocessed the collected data and derived some new variables and attributes for analyzing. Next, we analyze based on statistical method and Apriori algorithm. The result shows that many large-scale accident has occurred by vans in daytime. Medium-scale accident has occurred more in day than nighttime, and by cars more than vans. Small-scale accident has occurred more in night time than day time, however, the numbers were similar. Also, car-human accident is more occurred than car-car accident in small-scale accident.
