Purpose: Submandibular gland tumor is rare, less than 6% of head and neck tumor. The purpose of this article is to analysis the clinical experience and treatment outcomes of malignant submandibular gland tumor, suggesting a guideline of management. Methods: We retrospectively evaluated 26 patients who underwent operation for malignant submandibular gland tumor at Severence hospital between 1986 and 2004. Statistical analysis was performed by Kaplan-Meier method, log rank test, Chi-square test, Fisher's exact test using SPSS v12.0 for Windows. Results: They consisted of 18 males and 8 females whose median age was 47 years(range: 20-71). 10 cases of adenocystic carcinoma, 8 cases of carcinoma ex pleomorphic adenoma, 4 cases of mucoepidermoid carcinoma, 1 case each for acinic cell carcinoma, undifferentiated carcinoma, adeno carcinoma, epithelioid hemangioendothelioma. Sialoadenectomy only was performed in 10 cases(36.5%) and sialoadenectomy with neck node dissection was performed in 16 cases(63.5%). Adjuvant radiotherapy was done in 22 cases(84.6%). 10 year disease free survival rate for malignant submandibular gland tumor was 63.1 % and 10 year overall survival rate for malignant submandibular gland tumor was 70.1%. In univariate analysis, prognostic factors affecting recurrence of malignant submandibular gland tumor was initially papable lateral neck node in physical examination and metastasis of lateral neck node in pathologic confirmation. The prognostic factors affecting survival of malignant submandibular gland tumor was tumor size, TNM stage, recurrence and type of recurrence. Conclusion: In this study, prognostic factors affecting recurrence of malignant submandibular gland tumor was initially papable lateral neck node in physical examination and metastasis of lateral neck node in pathologic confirmation. The prognostic factors affecting survival of malignant submandibular gland tumor was tumor size, TNM stage, recurrence and type of recurrence. To prevent recurrence and to improve survival, early diagnosis and aggressive surgery must be considered.

김영삼(Young Sam Kim),전치훈(Chi Hoon Jeon),Erdenebat Tumur-Ochir,염영진(Young Jin Yum) 대한기계학회 2011 大韓機械學會論文集A Vol.35 No.12

자동차 인스트루먼트 패널에 사용되는 플라스틱의 온도와 시간에 따른 기계적 거동을 알아보기 위해 시편에 대한 인장 및 크리프 시험을 수행하였다. 여러 가지 온도에서의 물성치를 구한 결과 온도에 따라 물성치가 크게 변화함을 알 수 있었다. 4 가지 하중조건하에서의 3 점굽힘 크리프시험을 수행하고 지수법칙의 시간경화식을 적용하여 각종 계수를 구하고 크리프 거동을 간단한 식으로 표현하였다. 유한요소 크리프 해석 결과 하중이 커짐에 따라 수치해석 결과와 실험 결과가 차이가 커지지만 대체적으로 두 결과가 유사한 것을 확인할 수 있었다. Tensile and creep tests were performed at various temperatures to investigate the mechanical properties of plastics used in automotive instrument panels. Mechanical properties such as Young’s modulus and Poisson’s ratios changed markedly with the test temperature. Three-point bending creep tests were performed for three kinds of plastics under four loading conditions. Coefficients in the time-hardening power law creep equation were obtained from the experiment, and the creep behavior was represented by a simple expression. The results of finite element creep analysis showed good agreement with the experimental results, while the difference between the numerical and experimental results increased with the load.

안치영(Chi-Young Ahn),김현수(Hyun-Soo Kim),김원빈(Won-bin Kim),오창훈(Chang-hoon Oh),홍지영(Jee-Young Hong),김은영(Eun-Young Kim),이무식(Moo-Sik Lee) 한국농촌의학 지역보건학회 2017 농촌의학·지역보건 Vol.42 No.1

지역보건의료계획서에서 비전은 각 지역의 보건의료계획을 나타내는 핵심요소임에도 불구하고 작성방법에 대한 구체적인 지침이 부재하여 각 지역의 비전은 매우 다양하게 표현되어 있다. 이에 이 연구에서는 제6기 지역보건의료계획에서 제시한 비전 문구를 보건소 유형별, 권역별로 분석하였다. 전국 229개 지역의 제6기 지역보건의료계획서의 비전 문구와 이와 관련된 미션, 전략체계도, 중장기 추진과제 등을 대상으로 하였다. 지역을 권역별 4개, 읍·면·동 구성에 따른 보건소 유형을 4개로 분류하였고, 각 지역 비전의 글자 수, 문장 평가, 단어 빈도, 문구 평가를 빈도분석과 카이제곱검정, 일원배치분산분석을 이용하여 분석하였다. 비전의 글자 수가 17자 이하인 보건소가 172개소(75.1%)였고, 보건소 유형별로 유의한 차이가 있었다(p<0.05). 문구에 대한 수사표현에서 비유법(37.1%)이, 한글 외에 표현 언어 사용에서는 특수문자(43.2%)가 많았으며, 보건소 유형별로 유의한 차이가 있었다(p<0.01). 비전에 사용된 단어들은 ‘건강’, ‘행복’, ‘함께’, ‘군민’ 또는 ‘시민’, ‘도시’, ‘100세’ 등이었다. 문구평가 점수에서는 특·광역시 및 수도권에서 가장 높았으며, 보건소 유형 및 권역별로 유의한 차이를 보였다(p<0.05). 보건소 유형별로 과정 및 평가 영역, 공유가능성 등에서 유의한 차이가 있었다(p<0.01). 방향성은 충청권, 수도권 순으로 권역별로 유의한 차이가 있었으며(p<0.01), 미래지향성 및 공유가능성은 영남권이 가장 높아 권역별로 유의한 차이가 있었다(p<0.01). 비전은 지역보건의료계획에 가장 중요 요소 중 하나이다. 이 연구는 지역사회 특성별로 비전의 설정이 다름을 확인하였으며, 이러한 결과를 통하여 지역보건의료계획 등 보건소 비전 수립시 참고가 될 수 있는 기초적인 자료가 될 것으로 판단된다. Objectives: In this study, we analyzed vision statements of the 6th community health plan of local government in Korea. Methods: We examined vision statements letters, missions and strategy plans, and long-term missions of 6th community health plans of 229 local government in Korea. We also analyzed the numbers of vision letters, sentence examination, word frequency, each vision statement with frequency analysis, chi-square test, and one-way ANOVA. Results: Among 229 local government, 172(75.1%) of local government had the number of letters (Korean) less than 17 of vision statements, and there were a significant differences according to type of community health centers (p<0.05). Figuration (37.1%) were the most used in an expression of vision statement sentence, and special characters (43.2%) were the most used language except Korean. The most commonly used words of vision statement in order of frequency were ‘health’, ‘happiness’, ‘with’, ‘citizen’, ‘city’, ‘100 years old’ etc. Chungcheong provinces and Daejeon metropolitan city had a highest score in directionality on phrase evaluation, and there were a significant differences according to regional classes of local government (p<0.01). Gyeongsang provinces, Ulsan, Daegu, and Busan metropolitan cities had a highest score in future orientation and sharing possibilities on phrase evaluation, and there were a significant differences according to regional classes of local government (p<0.01). Conclusions: Vision is one of the most important component of community health plan. We need more detailed ‘vision statement guideline’ and the community health care centers of local government should effort to make more clear and complete their vision.

Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

정인원,김헌,홍주봉,지경환,이규영 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.6

연구목적 : 알코올 대사와 중추신경계내의 알코올 작용부위와 관련한 일부 후보유전자들이 알코올 의존과 관련이 있는지를 확인하고자 하였다. 방 법 : DSM-IV로 진단된 알코올 의존 환자 128명과 정상 대조군 128명을 대상으로 후보 유전자들의 다형성을 중합효소 연쇄반응과 제한효소처리법을 이용하여 동정하였다. 여기서 분리된 대립유전자와 유전자형에 따른 빈도의 차이를 유전자별로 각각 비교하였으며, 알코올 의존에 작용하는 서로 다른 유전자들에 의한 영향력을 배제하기 위하여 logistic regression 분석을 적용하였다. 결 과 : 알코올 의존군에서는 ALDH_2 유전자의 NN(wild type)형이 정상대조군에 비하여 유의하게 많았다(chi-square test, p<0.001). logistic regression analysis를 통하여 다른 유전자들에 의한 영향을 보정한 상태에서 ALDH_2가 NN(wild type)인 경우 다른 아형에 비하여 알코올 의존에 대한 odds ratio는 130.312이며 그 신뢰구간은 (17.22, 986.43)이었다. 한편, ASA는 N-glycosylation 부위에 변이형 대립유전자를 갖고 있는 경우(AG or GG)는 wild type에 비하여 알코올 의존에 대한 위험도는 2.344배이며 그 95% 신뢰구간은 (1.128, 4.871)이었다. 결 론 : 알코올 의존과 ALDH_2 유전자간에는 밀접한 연관성이 확인되었다. 또한 다른 유전자들은 개별 연관분석에서 의미있는 연관성이 관찰되지는 않았지만 logistic regression analysis를 통하여 N-glycosylation 부위에 다형성이 있는 ASA 유전자가 알코올 의존과 관련이 있음을 시사하였다. Objectives : This study was to explore the association between alcohol dependence and five candidate genes related to the metabolism of alcohol and the enzymes of the suspected sites in CNS. Methods : The genotype and allele frequencies of five candidate genes in 128 male hospitalized patients who met DSM-IV criteria for alcohol dependence were compared with 128 age-matched healthy male control subjects using polymerase chain reaction and restriction fragment length polymorphism. A logistic regression analysis was applied in order to exclude the reciprocal interactions among five candidate genes. Results : The NN genotype frequency of the ALDH_2 gene was significantly higher in alcoholic patients than in control subjects(chi-square test, p<0.001). No difference in frequency was found in the other four genes. In a logistic regression analysis, the odds ratio for alcohol dependence in the NN genotype of the ALDH_2 gene and AG or GG genotypes of the N glycosylation site on the ASA gene were 130.312(95% confidence interval, 17.22-986.43) and 2.344(95% confidence interval. 1.128-4.871), respectively. Conclusion : The result reiterates the association of the ALDH_2 gene polyporphism and the alcohol dependence. Logistic regression analysis additionally suggested that the N-glycosylation site on the ASA gene was associated with alcohol dependence.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Deep burns of the face & lips often lead to scarring and contraction of the circum-oral tissues with a marked reduction in the size of the oral aperture. Such burns most commonly caused by electrical contact, for example, children sucking electric plugs, or as a result of chemical burns and the exposture to flame. Once having burns, burned tissue may contract and reduce considerably the size and mobility of the mouth ; therefore bring up the resultant functional disturbance, verbal difficulty, even disgestive difficulty, and poor appearance, which fall into difficulty in social acceptability, caused by burns. In our department, 2 patients who were complain of functional limitations and esthetic problem owing to scar contracture, were visited, and we treated this microstomia with scar excision, graft and flap technique, and postoperative intensive physical therapy. We obtained relatively favorable results, thus report this cases with literature review.

Trauma in the elderly is a different disease than in the young. Not only do the elderly suffer different types of injuries, but their response to injury and their ultimate outcome are quite different. Over a 5 year period, 125 patients more than 65 years of age with traumatic injuries were evaluated retrospectively at Yongdong Severence Hospital for a clinical review of geriatric trauma. The analysis incoporated preexisting disease, mechanisme of injury, body region of injury, Injury Severity Score, change from level of preinjury function, and mortality. The population had a mean age 72 years and a low overall level of injury with a mean Injury Severity Score of 9. All patients had blunt. Injury secondary to falls(57%), pedestrian-motor vehicle accidents(32%), motor vehicle accident(8%), or assault(3%). The extremity region was most frequently injured(78%), and 30% had multiple body region injured. Overall mortality was 8%. All patients were independent regarding their activities of daily living at the time of the injury. Only 55% of survivals was independent at 1 year. The remaining 45% of survivals required some form of assistance.
