Kim 등 (2006)과 Kim 등 (2009)은 2002년에 (사)볼런티어 21에서 조사한 설문자료에 기초하여 우리나라 개인의 기부횟수에 영향을 주는 유의적 설명변수를 보고한 바 있다. 본고에서는 Kim 등 (2006)과 Kim 등 (2009)의 계산오류를 발견하여 이를 수정하고, 아울러 Kim 등 (2009)이 적용한 0이 팽창된 포아송 모형에 로지스틱 회귀모형을 추가하였다. 동 로지스틱 모형으로 기부행위(0, 1)에 영향을 주는 설명변수를 식별하고, 아울러 기부횟수가 작은 군(群)과 큰 군(群)을 판별하여 주는 설명변수를 식별하고자 한다. Kim et al. (2006) and Kim et al. (2009) reported a set of explanatory variables affecting donation frequency when they analyzed nationwide survey data on donations collected in 2002 by Volunteer 21, a nonprofit organization in Korea. The primary purpose of this paper is to correct computational errors found in Kim et al. (2006) and Kim et al. (2009), to rectify major results in the Tables and Figures and to supplement Kim et al. (2009) by providing new results. We add two logistic regressions to the ZIP and a mixture of two Poisson regressions of Kim et al. (2009). Through these two logistic regressions we could detect a set of explanatory variables affecting donation activity (0 or 1) and another set of explanatory variables, in which the volunteer (0, 1) variable is common, discriminating the infrequent donor group from the frequent donor group.

Outer membrane proteins(OMPs) of Brucella abortus 1119-3 strain were extracted by Triton X-100 treatment, and fractionated by DEAE-cellulose column chromatography and Sephacryl S-300 column chromatography. The antigenic proteins in these fractions were identified by Western blot analysis. In Western blot analysis, a single band(38kDa) was observed in the DEAE fractions from 36th fraction to 38th fraction against sera of cattle infected with B abortus. And other fractions have several bands. However, the Sephacryl S-300 fractions exhibited a total of 3 peaks of proteins with a broad range from about 30 to 116kDa. In order to characterize further, the extracted OMPs and the DEAE fractions were analyzed by two dimensional polyacrylamide gel electrophoresis(2-DE) and Western blot using serum from naturally infected cattle with Brucella spp. The 2-DE immunoblots of DEAE fraction showed immunoreactive spots more than twenty two. The major protein spots have ranging from about 32 to 47kDa. The pI values of the spots were detected from pH 4.7 to 5.4. Among the major protein spots, the 38kDa protein which is a specific antigen, located at the point of approximately a pI 4.8.

김병수,김종원,이인규,김동출,김우호,이혁준,양한광,Kim, Byung-Soo,Kim, Jong-Won,Lee, In-Kyu,Kim, Dong-Chul,Kim, Woo Ho,Lee, Hyuk-Joon,Yang, Han-Kwang 대한위암학회 2007 대한위암학회지 Vol.7 No.1

악성빈혈을 동반한 자가면역성 만성 위축성 위염은 위암의 전구 병변으로 알려져 있다. 저자들은 악성빈혈에 동반된 위암 1예를 경험하였기에 보고한다. 40세 여자환자가 어지럼증과 공복 시 속쓰림으로 시행한 혈액검사상 혈색소 4.2 g/dl으로 측정되었다. 상부위장관 내시경상에서는 위 고위 체부의 편평 융기성 병변이 관찰되었고 조직검사상 위선암으로 보고되었다. 위전절제술을 시행하였고 병리조직 검사상 병변은 고위 체부 전벽에 점막하층(SM2)까지 침범한 조기위암이었으며, 검사된 림프절 44개 중에 전이된 림프절은 없었다. 악성빈혈 환자에서 위축성 위염이 동반된 경우 위암의 호발연령이 되면 위암의 발생 가능성이 있으므로 상부위장관 내시경의 주기적인 시행이 중요하리라 생각된다. Increased risk of gastric cancer has been reported in patients with chronic atrophic gastritis that develops in conjunction with pernicious anemia. We report here a case of a gastric adenocarcinoma associated with pernicious anemia. A 40-year-old female patient had been diagnosed with anemia 6 years earlier at a local hospital. One month ago, she visited our hospital for aggravated dizziness and newly developed epigastric soreness. Her blood hemoglobin level was 4.2 g/dl, and a gastroscopic work-up for anemia discovered a 2.5-cm-sized, slightly elevated mucosal lesion at the anterior wall of the high body in the stomach. The biopsy of this lesion revealed a moderately-differentiated adenocarcinoma. She underwent a total gastrectomy with a Roux en Y esophagojejunostomy with D2 lymph node dissection. The final stage of the gastric carcinoma was identified as T1N0M0. Based on this experience, we recommend that a follow-up gastroscopy be performed in patients with pernicious anemia with atrophic gastritis because of the increased risk of gastric cancer in patients with pernicious anemia.

Purpose : It is very important to endow the cancer patients underwent chemotherapy with satisfactory quality of life (QOL). However, little is known about the factors influencing QOL during chemotherapy. Therefore, we designed this study to find out the factors influencing QOL in the cancer patients who underwent chemotherapy. Methods : Ninety-seven cancer patients were studied, prospectively. The patients' characteristics were as follows; median age(range): 48(19{\sim}83) years, male:female; 57:40, PS:0,1/2,3;55/42 patients, diagnosis(number): lymphoma (28), lung cancer (22), gastrointestinal cancer (18), sarcoma (12), breast cancer (12), gynecological cancer (5), Stage: I,II/III.IV;37/60 patients. We used EORTC QLQ-C30 questionnaires to evaluate QOL. EORTC QLQ-C30 scores were performed before the onset of chemotherapy and after the end of 3 cycles of chemotherapy. The correlation of these scores with performance status (PS), diagnosis, disease stage, response to chemotherapy, and regimen related toxicity was evaluated. Results : The responder group (CR, PR) demonstrated marked improvement of social functional and emotional scales to non-responder group (SD,PD) (P=0.024, 0.045). Non-hematologic regimen related toxicity such as mucositis, nausea and vomiting was significantly correlated with pain scale change (P=0.043). Other factors had no notable correlation with QOL changes. Conclusion : Our preliminary study results may suggest as follows. The response to chemotherapy is associated with the change of social functional and emotional scales and the severity of non-hematologic regimen related toxicity is associated with pain scale change.

양극성 경향과 스트레스 취약성:기분장애설문지 양성 반응군과 음성 반응군에서 지각된 스트레스, A형 행동, 그리고 생활습관의 비교

김병수,김성윤,최재원,주연호,윤대현,한내진,김유신,김선옥,Kim, Byung-Su,Kim, Seong-Yoon,Choe, Jae-Won,Joo, Yeon-Ho,Yoon, Dae-Hyun,Han, Nae-Jin,Kim, Yoo-Shin,Kim, Seon-Ok 한국정신신체의학회 2010 정신신체의학 Vol.18 No.1

연구목적 : 본 연구를 통해 양극성 장애 I형 혹은 II형 진단 기준에는 부합하지 않지만, (경)조증적 성향 혹은 기분 불안정성 등의 양극성 경향(bipolar tendency, bipolarity)을 가진 사람에게서, 주관적으로 지각하는 스트레스 수준, 스트레스 취약성을 반영하는 것으로 알려진 A형 행동 유형(Type A Behavior Pattern, TABP), 그리고 건강하지 못한 생활습관의 위험이 증가되어 있는지 확인하고자 한다. 방 법 : 정신과적 병력이 없는 30세 이상의 1987명의 연구 대상군이 분석에 포함되었다. 이들 중에서 기분장애설문지 (Mood Disorder Questionnaire, MDQ)의 (경)조증적 증상 경험에 대한 13개 항목 중에서 7개 항목에 "예"라고 응답한 사람들을 양극성 경향군으로 분류하였다. 양극성 경향군과 비양극성 경향군 사이에서 지각된 스트레스 척도(Perceived stress scale, PSS), TABP를 반영하는 A/B 생활 습관 설문(A/B Lifestyle ques-tionnaire) 점수와, 음주, 흡연, 불규칙적인 식사, 운동 부족 등의 생활 습관 변인을 비교하였다. 결 과 : 양극성 경향군(329명, 16.6%)은 비양극성 경향군에 비해 TABP를 반영하는 A/B 생활 습관 설문의 총 점수가 유의미하게 높았으며(125.4점 vs. 115.9점, p<0.001), TABP로 판정(총 점수 135점 이상)된 비율도 양극성 경향군에서 유의미하게 높은 것으로 관찰되었다(41.3% vs. 30.1%, p<0.001). 주관적으로 지각하는 스트레스 수준의 비교에서도, 양극성 경향군이 비양극성 경향군에 비해 유의미하게 높았다(18.5 vs. 16.5, p<0.001). 생활습관의 비교에서 '불규칙적인 식사'(20.1% vs. 14.3%, p=0.002), '주 4회 이상 음주'(29.8% vs. 16.5%, p<0.001), '현재 흡연'(41.9% vs. 23.0%, p<0.001), '주 2회 이하 운동'(63.2% vs. 55.1%, p=0.007) 이라고 응답한 사람의 비율이 양극성 경향군에서 유의미하게 높았다. 결 론 : 양극성 경향을 가진 경우는 스트레스에 취약한 행동 양상이 높게 관찰되고, 주관적으로 지각하는 스트레스 수준도 높고 흡연, 음주, 불규칙한 식사와 운동 부족과 같은 건강하지 못한 생활 습관을 가지고 있을 위험도 높은 것으로 확인되었다. 이러한 위험 요소들은 비만, 대사증후군, 당뇨, 그리고 심혈관계 질환의 발병 위험을 높일 수 있으므로, 양극성 경향을 가진 사람들은 스트레스 관리 및 건강한 생활 습관을 유지하기 위한 보다 적극적인 노력이 필요하다. Objectives:Authors hypothesized that bipolar tendency of non-psychiatric person would be associated with stress vulnerability. To test the hypothesis, we compared perceived stress level, Type A Behavioral Pattern (TABP) and unhealthy lifestyle between person with and without bipolar tendency. Methods:The study cohort consisted of 1987 subjects without past and current psychiatric history. In this study, bipolar tendency was determined by MDQ response which requires endorsement of at least 7 of the 13 "yes or no" questions. We compared the scores of Perceived Stress Scale, A/B lifestyle questionnaire, and unhealthy lifestyle(alcohol, smoking, lack of exercise, irregular meal) between MDQ positive and negative respondents. Results:We identified the bipolar tendency group determined by the MDQ positive response were 329 subjects(16.6%). The overall score of the bipolar tendency group was significantly high on the A/B lifestyle questionnaire compared to the non-bipolar tendency group(125.4 vs. 115.9, p<0.001), and the rate of the subjects defined as TABP was also significantly high(41.3% vs. 30.1%, p<0.001). In comparison of subjectively perceived stress level, the bipolar tendency group was observed to be significantly higher than the non-bipolar tendency group (18.5% vs. 16.5%, p<0.001). The bipolar tendency group was significantly higher than the non-bipolar tendency group on the rate of answering:'irregular eating habit' (20.1% vs. 14.3%, p=0.002), '4-or-more-times alcohol intake per week' (29.8% vs. 16.5%, p<0.001), 'currently smoking' (41.9% vs. 23.0%, p<0.001), '2-or-less-times physical exercises per week' (63.2% vs. 55.1%, p=0.007). Conclusion:By clinical diagnosis, even a person who does not meet the criteria of bipolar disorder has a high risk of stress-related behavioral pattern, and perceived stress when possessing bipolar tendencies such as the (hypo) maniac tendency or affective instability. Such individual has significantly higher risk of having unhealthy life-style such as smoking, drinking, irregular eating habit and lack of exercise compared to non-bipolar tendency group. Since these risk factors lead to increase the risk of obesity, metabolic syndrome, diabetes, and cardiovascular diseases, the individual with the bipolar tendency requires a more effort to manage stress and to maintain healthy lifestyle.
