李金永,呂邑東 全北大學校 1981 論文集 Vol.23 No.-

韓國人類集團의 PTC (phenylthiocarbamide) 味覺에 대한 頻度의 平均値와 味盲과 血液型과의 關係를 糾明하기 위하여 그 一環으로 嶺東地方에 있어서 男女 中高等學校 學生을 對象으로 調査하여 다음과 같은 結果를 얻었다. 1. PTC 味覺은 크게 taster와 non-taster(味盲)로 區分된다. 그 中 taster는 쓴맛, 신맛, 단맛, 기타의 맛 頻度順으로 나타났다. PTC 濃度 C_1(1,300.00 ㎎/ℓ)에서 味盲의 頻度는 9.9%이었고 期待와는 달리 C_10에서는 훨씬 낮은 頻度를 나타내었다(61.2%). 쓴맛과 味盲의 頻度曲綠은 C_6과 C_7 사이에서 交叉되었다. C_13 以上의 低濃度에서의 味盲의 頻度는 거의 一定한 頻度의 傾向을 나타내었다. 2. 신맛, 단맛, 기타의 맛의 頻度는 PTC 濃度에 關係없이 男子가 女子보다 더 높았다. 특히, C_1에서의 味盲의 頻度는 男子가 9.6%, 女子가 10.6%를 나타내었고 高濃度(C_1~C_5)에서는 女子가 男子보다 PTC 味覺에 더 銳敏함을 나타내는 반면에 低濃度(C_6~C_17)에서는 그 反對現象이였다. 3. C_1에서의 血液型 A型의 味盲頻度는 11.8%, O型이 9.8%, AB型이 9.6%, B型이 8.5%였다. 이와 같이 이러한 頻度는 PTC 濃度가 낮아짐에 따라 거의 一定한 頻度의 傾向을 나타내었다. To investigate the frequency of PTC (phenylthiocarbamide) non-taster and relationship between non-taster and blood type, middle and high school students in Yeongdong population of Gangwondo province, Korea were studied. The results are as follows : 1. Most of the tasters tasted PTC as bitter. However some tasted as sour, sweet and other in the order of frequency. Frequency of non-taster of C_1 was 9.9%. That of C_10 was unexpectedly low (61.2%). The curves of bitter and non-taster was crossed between C_6 and C_7. the In lower concentrations than C_13, the frequencies of non-taster were inconsistent. 2. The frequencies of sour, sweet and other taster in male were higher than in female. Especially, the frequency of non-taster of C_1 was 9.6% in male and 10.6% in female. Whereas male was more sensitive to the high concentrations(C_1~C_5) of PTC, female was more sensitive to the lower concentrations(C_6~C17). 3. Among the non-taster of C_1, the frequency of blood type A was 11.8%, O 9.8%, AB 9.6%, and B 8.5%. This frequencies invariably changed as the PTC concentration become lower.

N/A Background: Proliferative diabetic retinopathy (PDR), a late stage of diabetic retinopathy, is the com- monest cause of acquired blindness in adults. Despite many previous studies, the risk factors for the development of PDR in Korean NIDDM patients have not been precisely defined yet. The aims of the present study were to evaluate the incidence and the risk factors of PDR. Method: From April to June 1993, we retrospectively studied 243 NIDDM outpatients (duration of diabetes 7.9±7.1, age 54.5±10.8, male 110 and fema1e 133) who had undertaken fundoscopic examination for diabetic retinopathy before April 1991. At the time of the examination, 70 patients had nonproliferative diabetic retinopathy (NPDR). Of those, 12 patients progressed to PDR and 58 patients did not. Clinical characteristics and laboratory findings of progressed group were compared with non-progressed group. Results: Of the 162 patients who were free of diabetic retinopathy at the initial examination, 18 patients progressed to diabetic retinopathy; the incidence rate of diabetic retinopathy was 34.9/1,000 person-yr. Of these, 1 patients had PDR (1.9/1,000 person-yr). After 2.6 years of mean follow-up, 12 out of 70 patients with initial NPDR progressed to PDR. The incidence rate of PDR in the patients with NPDR was 63.2/1,000 person-yr. Microalbuminuria, more severe weight loss, lower level of C-peptide and insulin therapy were associated with an increased 2.6-year risk of developing PDR. However, sex, smoking, use of antihypertensive drugs or aspirin, age, duration of diabetes and the mean fasting serum glucose, hemoglobin Al, cholesterol, systolic or diastolic blood pressure levels during the follow-up period were not associated with the progression to PDR. Forward stepwise multiple logistic regression analysis revealed that initial microalbuminuria and delta BMI are significant independent predictor for the progression to PDR. Conclusion: Microalbuminuria can be used as a predictor for progression to PDR. Lower level of C-peptide, more severe weight loss and current insulin use may be also the risk factors for progression to PDR in Korean NIDDM patients with nonproliferative retinopathy. However, long-term prospective study is warranted to answer the question more properly.

In many respects, accelerometers are convenient for measuring the lateral vibrations of a gun tube under impulse loads. Reliable measurements by accelerometers must overcome two issues: exceedingly large acceleration at high frequencies due to stress waves, and the elimination of drifts accumulating through the integration of acceleration signals. In this paper, we use a mechanical filter that reduces the effect of stress waves. Also, we propose a new double integration algorithm based on multi-resolution wavelet decomposition. Using a test-rig, we measure the vibration characteristics of commercially-available damping materials. Based on the test results, we design a mechanical filter and experimentally verify the performance of the filter. The proposed double integration algorithm is shown to be as effective as other existing algorithms without arbitrary selection of parameters.

Background/Aims: Churg-Strauss syndrome (CSS) is a rare systemic necrotizing small-vessel vasculitis, with accompanying bronchial asthma, eosinophilia, and eosinophilic infiltration of various tissues. The purposes of our study were to characterize the clinical features of CSS and to identify factors associated with CSS prognosis in Koreans. Methods: Medical records were reviewed retrospectively for all physician-diagnosed CSS patients in the Seoul National University Hospital between January 1990 and March 2011. Results: Data from 52 CSS patients were analyzed. The respiratory tract was the most commonly involved organ (90.4%). Renal involvement was less frequent in antineutrophilic cytoplasmic antibody (ANCA)(-) patients than in ANCA(+) patients (p = 0.048). Clinical remission occurred in 95.3% of patients, but 16.3% of them relapsed. Patients who maintained remission for more than 6 months were relatively older (median, 51 years) at diagnosis (p = 0.004), had been diagnosed in earlier stages (p = 0.027), showed more frequent respiratory involvement (p = 0.024) and generalized symptoms (p = 0.039), and showed less frequent cutaneous involvement (p = 0.030) than those who did not achieve persistent (> 6 months) remission. Patients who achieved persistent remission also showed higher C-reactive protein (CRP) levels (p = 0.031) than those who did not. Conclusions: ANCA(-) CSS patients showed less frequent renal involvement. Characteristics of good responders were older age, diagnosis at earlier stages, less cutaneous involvement, more respiratory involvement, high CRP values, and more generalized symptoms.

최근 정보통신 기반의 디지털 경제시대를 맞아 유무선 통합(Fixed-mobile convergence)서비스에 관한 사안들은 통신시장의 주요이슈로 떠오르는 것 중 하나 이다. 우리나라의 경우 이미 유선 통신사업부문에서 다양한 인터넷 응용서비스의 등장으로 세계 최고 수준의 초고속 접속사업을 성공적으로 추진함과 동시에 통신망의 광대역화를 급속히 진행시키고 있다. 또한, 무선 통신사업 부문 역시 이동통신의 급성장이 두드러져 세계 제 6위의 이동전화 보급국가로 성장하였으며, 거의 대다수의 가구가 이동전화를 보유하고 있는 것으로 나타나고 있다. 한편, 무선인터넷, 초고속 데이터, 동영상 등과 같은 초고속 멀티미디어 서비스가 가능한 이동통신망 광대역화도 본격적으로 추진 중에 있다. 따라서 유무선에 있어서 기존의 강력한 인프라를 기반으로한 두 영역간의 통합 서비스가 제공된다면 시너지 제고는 물론 통합 인프라에 의한 무한가치가 창출됨으로 인해 정보통신 선진국으로 진일보 할 수 있는 기회가 제공될 것이다. 따라서 본 연구에서는 유무선 통합서비스의 개념과 종류, 유무선 통합서비스 관련 시장동향, 기회요소와 위협요소, 주요 국가의 규제 현황 등을 살펴보고 더불어 유무선 통합서비스 환경하의 마케팅 패러다임 분석을 실시하고자 한다. Fixed-mobile convergence services can be defined as the combination of previously separate fixed and mobile services, and networks and commercial practices. Examples of fixed-mobile convergence services include single voicemail box, single number and unified messaging across fixed and mobile networks. Recently as more voice is transferred to mobile networks, convergence services between fixed and mobile become more important. In Korea convergence services are only starting to become established, and are likely to become an important part of any operator's offering. In this paper, we search the different levels of fixed-mobile convergence services and the trends and regulations for fixed-mobile convergence services in major countries. And at the same time, we also suggest the corresponding Marketing strategies by operaters related to fixed-mobile convergence services.

Background and Aim: Oxaliplatin hypersensitivity is a well-known adverse reaction but the prevalence varies and data for frequency and clinical features have not been reported for Korea. Here we evaluates the prevalence and risk factors for hypersensitivity reactions to oxaliplatin after chemotherapy. Methods: Clinical information on all patients treated with oxaliplatin was retrospectively reviewed in electronic medical records between August 2009 and July 2010 in Seoul National University Bundang Hospital. Patients who experienced hypersensitivity reactions to oxaliplatin were compared with those who did not. Results: A total of 393 patients received oxaliplatin, with 42 (10.7%) experiencing hypersensitivity reactions including three cases of anaphylaxis. Median cycle of the first hypersensitivity reaction was 8. Reactions correlated with lower dexamethasone doses. Other variables were not significant. Conclusions: The prevalence of hypersensitivity reactions was 10.7%, symptoms being mostly mild and cutaneous. Lower dexamethasone doses could be a predictor for hypersensitivity reactions to oxaliplatin.

In recent year, the u-City construction projects which integrate IT technology into urban infrastructures are being pushed forward by many local governments. These projects contain various purposes in an aspect of regional economy : to reinforce a competitiveness of region by increasing efficiency of urban managements and to revitalize regional economy by stimulating the regional high-tech industries that related to u-City construction. In this context, regional economic impact assessment of u-City construction projects is particularly important because, it give us information about effectiveness of u-City construction policy as a stimulus of regional high-tech industries and the policy feasibility of u-City construction projects that can be a base of public projects. However, it is challenging to assess the impact of u-City projects on regional economy properly due to a lack of understanding about industrial classification. and specific industrial inputs related to u-City construction. In this study, we suggest u-City industrial classifications, and specific-industrial inputs induced by u-City construction projects based on associated legislations. business report for a u-City construction, and results from previous studies. Using these classification and industrial input, we also investigate the regional economic impacts of a u-City construction project in Wha-sung and Dong-tan cities employing Input-output analysis. The empirical results suggests that u-City industries have. relatively high in production inducement, and value added inducement compared to input of other industrial sectors. These results indicate that regional economic impact of a Wha-sung and Dong-tan u-City construction project are relatively high, but economic impacts of u-City construction projects vary according to the regional industrial structure, and the specific expense accounts of u-City construction projects.
