Evaluation of Social Nicotine Dependence Using the Kano Test for Social Nicotine Dependence (KTSND-K) Questionnaire in Korea

BACKGROUND: Smoking is one of the most important leading causes of morbidity and mortality. Smoking habit is recognized as nicotine dependence, which consists of physical and psychosocial dependence. To evaluate social nicotine dependence, the Kano Test for Social Nicotine Dependence (KTSND) working group developed a new questionnaire, which consists of 10 questions with a total score of 30 in Japan. We examined the social nicotine dependence among healthy adults using the new KTSND questionnaire and evaluated validity of the KTSND questionnaire in Korea. METHOD: We applied Korean KTSND questionnaire version 2 to employees of hospital, university students and people for medical examination and promotion test. Complete data obtained from the 741 responders were analyzed. RESULT: The mean age of responders was 31.8 years. Among them, males were 57.8%. Current smokers, ex-smokers, and non-smokers were 13.8%, 12.8%, and 73.4% respectively. According to smoking status, the total KTSND scores of current smokers were significantly higher than those of ex-smokers, and of non-smokers (17.1+/-5.4 versus 14.3+/-5.5, and 12.3+/-5.5, p or =4), This finding suggested that the psychosocial dependence might play a different role from physical nicotine dependence in smoking. Most of the non-smokers (62.5%) had an experience of harmful passive smoking especially in public place. CONCLUSION: Our study suggested that the KTSND questionnaire could be a useful method to evaluate psychosocial aspects of smokingope

A Case of Successful Management of Sarcoidosis with Chylothorax Using Octreotide

Sarcoidosis is a multi-system granulomatous disorder of an unknown etiology and affects individuals worldwide. It is characterized pathologically by the presence of non-caseating granulomas in more than one involved organ. However, pleural involvement of sarcoidosis is rare and there are no reported cases in Korea. Traditionally, sarcoidosis has often been treated with systemic corticosteroids or cytotoxic agents. In particular, chylothorax with sarcoidosis is usually treated with corticosteroid for approximately 3~6 months, followed by repeated therapeutic thoracentesis, talc pleurodesis, dietary treatment, or thoracic duct ligation where needed. We encountered a 46 years old female patient presenting with cough, dyspnea and both hilar lymphadenopathy (stage I) on chest radiograph. The patient was diagnosed with a non-caseating granuloma, sarcoidosis by a mediastinoscopic biopsy. For one month, she had suffered from dyspnea due to right side pleural effusion, which was clearly identified as a chylothorax on thoracentesis. Corticosteroid therapy with dietary adjustment was ineffective. She was treated successfully with a subcutaneous injection of octreotide for 3 weeks and oral corticosteroid. We report a case of successful and rapid treatment of chylothorax associated with sarcoidosis using octreotide and oral corticosteroid.ope

A Case of Pulmonary Choriocarcinoma

Pulmonary choriocarcinoma is a very rare tumor in men. Herrein, the case of a pulmonary choriocarcinoma in 39-year-old man, and whether it had a primary nature, is reported. He denied any prior medical illness, but was admitted to our hospital with a history of a cough, and progressive dyspnea and hemoptysis 2 and 1 week duration, respectively. Chest radiographs on admission revealed a huge lung mass, 10 cm in diameter, in the left upper lung field, with left pleural effusion. Although biopsies using several diagnostic methods for the pathological confirmation were attempted, the pathology was not confirmed. Finally, the patient died after 2 months of regression. An autopsy of the lung was then performed.ope

Importance-Performance Analysis on College Students' Conceptions of Academic Ethics

지식기반사회의 성숙과 함께 학문공동체에서는 연구윤리에 대한 담론이 활발하다. 연구윤리는 책임 있는 연 구수행을 위해 준수해야 할 윤리원칙 또는 행동양식이다. 이 연구는 학습하는 과정에서 개인적인 윤리 확립을 위한 실천방안을 마련하기 위하여 학습윤리에 대한 대학생의 인식을 조사·분석하는 것이 목적이다. 연구대상은 서울특별시 K대학교 공과대학 재학생 183(남: 142, 여: 41)명이며, 설문지는 ‘학습윤리’에 관한 내용으로 구성되 었다. 연구결과는 다음과 같다. 첫째, 대학생들은 보고서 작성 항목에서 대리작성, 아이디어 도용, 과제물 구매 등에서는 준수의 중요성을 높게 인식하고 있지만, 중복제출과 짜깁기에서는 중요성 인식의 정도가 낮았다. 학습 윤리에 대한 실행도(준수정도)에서는 대리작성, 중복제출, 과제물 구매 등에서 높게(즉, 위반하지 않는 것으로) 나타났으며, 짜깁기와 표절에서는 실행도가 낮았다. 중요도와 실행도 점수 차이는 중복제출, 짜깁기, 과제물 구 매, 표절, 대리작성에서 통계적으로 유의미하였다. 학습윤리 위반에 대한 이유는 ‘더 좋은 학점에 대한 욕심’, ‘시 간의 부족’, ‘자료에 대한 쉬운 접근성’이었다. 둘째, 기타 학업수행(출석, 협동과제, 시험 등) 측면에서 학습윤리 중요도는 대리시험, 시험부정행위, 무임승차에서는 높았지만 대리출석과 무단조퇴는 상대적으로 낮게 나타났으 며, 이들 항목에 대한 실행도에서도 비슷한 경향이 나타났다. 중요도-실행도 점수 차이는 대리출석, 무단조퇴, 대리시험에서 통계적으로 유의미하였다. 셋째, 학습윤리의 중요도와 실행도 차이 분석 결과, 중요도는 높으나 실행도가 낮은 약점 항목으로 집중관리가 필요한 부분은 ‘표절’, ‘위조’, ‘변조’로 나타났다. 중요도와 실행도가 모두 높은 강점 특성으로는 ‘과제물 구매’, ‘대리작성’, ‘아이디어 도용’과 ‘대리시험’, ‘무임승차’, ‘시험부정 행위’가 포함되었다. 중요도와 실행도의 인식 수준이 모두 낮은 항목은 ‘짜깁기’를 포함하여 ‘대리출석’, ‘무단조퇴’ 항목이다. 중요도는 낮지만 실행도는 비교적 높은 투자 및 집중도 조절이 요구되는 불필요한 강점 항목에는 ‘중복제출’ 이 포함되었다. Nowadays ‘academic honesty/academic integrity' becomes an important issue in the research community. The issue of ‘academic ethics’ is particularly relevant to college students. The purpose of the present study was to analyze college students' conceptions of ‘academic ethics'. For this purpose, one hundred eighty-three (142 males and 41 female) college students were recruited from K University in Seoul. The survey instrument used for the study consisted of thirteen questions regarding academic ethics. The results of the study were summarized as follows: First, the college students reported high importance in compliance with the items of agency creating, idea stealing, and homework buying, but they reported lower importance on the items of weaves in writing and duplicate submission. Second, students also reported high importance in compliance with the items of surrogate test, test cheating, and free riding in homeworks, but they reported lower importance on the items of valet attendance and unauthorized leaving early. For the items of performance, compliance scores showed a similar trend. Lastly, the results of the importance-performance analysis showed that the items of academic ethics in the 'concentrate' area were 'plagiarism', 'fake', and 'modulation', respectively. In conclusion, plagiarism as a violation of academic ethics may occur when students don't know how to appropriately quote from resources. In order to establish 'academic ethics' code for college students in university, we should design, develop, and implement appropriate courses such as 'research ethics,' 'academic writing,' etc
