윤근수,이교운,박용욱 울산과학대학 1999 연구논문집 Vol.26 No.1

한국어 정보처리를 하기 위해서는 가장 기초기술인 형태소 분석이 이루어져야 한다. 한국어의 용언은 어미의 활용으로 인하여 형태소분석을 상당히 까다롭게 하는 특성을 가지고 있으며, 대부분의 어절을 대상으로 용언의 불규칙 현상이 있는 지를 조사해야 하므로 시스템의 속도를 떨어뜨리게 된다. 따라서 이 논문에서는 용언 불규칙현상을 분류하고 알기 쉽도록 도식화하면, 전체 시스템의 속도를 높이기 위한 새로운 자료구조 도입과 알고리즘을 소개한다. Korean Morphological analysis is basic technic of Korean Information processing. Korean morphological analyzer is complicated because of irregular verbs. In this paper, we suggest analysis, diagram, and algorithm of korean irregular verbs processing. The system becomes very efficient because the number of dictionary accesses is minimized. The system makes easy to analyze unknown words like compound nouns without adding them to the dictionary.

Massive hemoptysis represents a major medical emergency that is associated with high mortality. The causes of hemoptysis are various and include pulmonary and cardiovascular disorders and trauma. The causes of pulmonary disorder are tuberculosis, bronchiectasis, abscess, malignancy, bronchitis, and fungal infection. The causes of cardiovascular disorder are mitral stenosis, pulmonary embolism, and congestive heart failure. A fistula between an aortic aneurysm and the pulmonary parenchyma is one of the causes of hemoptysis, but it is a rare. However, if undiagnosed, it is a uniformly fatal cause of massive hemoptysis. This is a case of bleeding from a fistula between an aortic arch aneurysm and a lung parenchyma in a patient with an aortic arch aneurysm who presented with massive hemoptysis. He had suffered intermittent hemoptysis since he was diagnosed with an aortic arch aneurysm three years before. A high clinical suspicion must be maintained when a history of intermittent hemoptysis is obtained in patients with an aortic aneurysm or prior aortic graft surgery.

Objectives: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachialankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. Methods: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed. The CCA-IMT, levels of carotid plaque, baPWV,and ankle-brachial index (ABI) of the subjects were assessed. We used non-mydriatic fundus photography to diagnose diabetic retinopathy. Multiple logistic regression analyses were used to evaluate the association between macroangiopathy and diabetic retinopathy. CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm,0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. Objectives: We evaluated the association between common carotid artery intima-media thickness (CCA-IMT), brachialankle pulse wave velocity (baPWV), carotid plaque, and peripheral arterial disease (PAD) as indicators of macroangiopathy and diabetic retinopathy as an indicator of microangiopathy in type 2 diabetic patients. Methods: We analyzed 605 type 2 diabetic patients registered at a public health center in Korea. Following overnight fasting, venous blood and urine samples were collected and analyzed.

CCA-IMT and baPWV were divided into tertiles: CCA-IMT, 0.39 to 0.65 mm,0.66 to 0.78 mm, and 0.79 to 1.30 mm; baPWV, 9.9 to 15.8 m/s, 15.9 to 18.9 m/s, and 19.0 to 38.0 m/s. Results: The association between baPWV and diabetic retinopathy remained significant after adjustment, with an increasing odds ratio (OR) in the second tertile (OR, 2.41; 95% confidence interval [CI], 1.27 to 4.55) and the third tertile (OR, 4.63;95% CI, 2.33 to 9.21). No significant differences were observed in carotid plaque, PAD, and each tertile of CCA-IMT. Conclusions: BaPWV was associated with diabetic retinopathy, while CCA-IMT, carotid plaque, and PAD were not. This study suggests that the association between macroangiopathy and microangiopathy may be attributable to functional processes rather than structural processes within the vascular system.

Yong-Joon Lee,Yongsung Suh,Jung-Sun Kim,Yun-Hyeong Cho,Kyeong Ho Yun,Yong Hoon Kim,Jae Young Cho,Ae-Young Her,Sungsoo Cho,Dong Woon Jeon,Sang-Yong Yoo,Deok-Kyu Cho,Bum-Kee Hong,Hyuckmoon Kwon,Sung-Jin 대한심장학회 2022 Korean Circulation Journal Vol.52 No.4

Background and Objectives: Identifying patients with high bleeding risk (HBR) is important when making decisions for antiplatelet therapy strategy. This study evaluated the impact of ticagrelor monotherapy after 3-month dual antiplatelet therapy (DAPT) according to HBR in acute coronary syndrome (ACS) patients treated with drug eluting stents (DESs). Methods: In this post-hoc analysis of the TICO trial, HBR was defined by 2 approaches: meeting Academic Research Consortium for HBR (ARC-HBR) criteria or Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent DAPT (PRECISE-DAPT) score ≥25. The primary outcome was a 3–12 months net adverse clinical event (composite of major bleeding and adverse cardiac and cerebrovascular events). Results: Of the 2,980 patients without adverse events during the first 3 months after DES implantation, 453 (15.2%) were HBR by ARC-HBR criteria and 504 (16.9%) were HBR by PRECISE-DAPT score. The primary outcome rate was higher in HBR versus non-HBR patients (by ARC-HBR criteria: hazard ratio [HR], 2.87; 95% confidence interval [CI], 1.76–4.69; p<0.001; by PRECISE-DAPT score: HR, 3.09; 95% CI, 1.92–4.98; p<0.001). Ticagrelor monotherapy after 3-month DAPT was associated with lower primary outcome rate than ticagrelor-based 12-month DAPT regardless of HBR by ARC-HBR criteria, with similar magnitudes of therapy effect for HBR and non-HBR patients (p-interaction=0.400). Results were consistent by PRECISE-DAPT score (p-interaction=0.178). Conclusions: In ACS patients treated with DESs, ticagrelor monotherapy after 3-month DAPT was associated with lower rate of adverse clinical outcomes regardless of HBR, with similar magnitudes of therapy effect between HBR and non-HBR.

세무대리인 서비스품질과 납세자만족도에 관한 연구

윤윤석(Yun Yun-Suk),김도형(Kim Do-Hyung),장용운(Jang Yong-Woon) 한국국제회계학회 2006 국제회계연구 Vol.0 No.16

세법이 매우 복잡해짐에 따라, 일반 납세자들 스스로 세법을 적절히 해석하고 적용하는데 어려움을 겪고 있다. 그러므로 납세자들은 세무업무를 수행하기 위하여 세무대리인에게 의존하고 있는 실정이다. 본 연구는 세무대리인의 서비스품질이 납세자의 만족도에 미치는 영향을 살펴보는 것이다. 기존의 연구들은 세무대리인의 5가지 서비스품질 즉, 세부담절약성, 정확성, 납세성실성, 전문가 자질성, 편의성 등이 납세자만족도에 유의적인 영향을 미치는 것으로 밝히고 있다. 마케팅 문헌들은 고객성, 정보제공성, 서비스의 신뢰성 같은 기타 서비스 품질이 필요성을 지적하고 있다. 세무업무를 세무대리인에게 위임하는 납세자들로부터 설문지를 수집하였다. 설문문항에 대한 요인분석을 수행한 후에 가설에 대한 회귀분석을 수행하였다. 8가지 서비스 품질을 검증한 결과 5가지 변수 즉 세부담절약성, 납세성실성, 편의성, 정보제공성, 신뢰성 등이 납세자만족도에 영향을 미치는 것으로 나타났다. 납세자만족도가 세무대리인과의 계속거래 의도에 대한 영향을 파악하기 위하여 매출액, 거래기간, 설립년도 등을 포함하여 로지스틱 분석을 수행하였다. 매출액, 거래기간, 설립년도 등의 변수들이 비유의적인 반면 납세자만족도가 높을수록 현재의 세무대리인과 계속거래의 의도가 있음을 보여주고 있다. Because tax laws are very complex, it is very difficult for general taxpayers to properly interpret and apply relevant tax rules by themselves. Therefore they rely on tax agents to perform their tax duties. This paper examines whether the service quality of a tax agent affects the taxpayer's satisfaction. Prior studies show that five qualities of tax agent's service, namely, tax savings, accuracy, faithfulness, professionalism, and convenience of tax service affect the taxpayer's satisfaction. Marketing literature indicates that other service qualities, such as customization, information provision and trustworthiness of service, also affect the taxpayer's satisfaction. Questionnaire were collected from the taxpayers who relied on tax agents for their tax reporting. After conducting factor analysis and Cronbach's a test one the raw data, we applied linear regression analysis to test hypotheses. Among the eight service qualities tested five service qualities are found to be significantly affect taxpayer's satisfaction, namely, tax savings, faithfulness, convenience, information provision, and trustworthiness of tax services. To examine whether the taxpayer's satisfaction affects her intent to stay with the current tax agent. We conducted a logistic analysis, using sales, duration of business and the age of tax paying company as control variables. Only taxpayer's satisfaction is found to significantly affect her intent to stay with the current tax agent.
