유병대,배규락,김계수 한국고객만족경영학회 2018 고객만족경영연구 Vol.20 No.1

The purpose of this study is to construct a research model and to execute empirical analysis based on the theoretical background of Holacracy (self management organization) and in a uncertain management circumstances. In particular, this study conducted a questionnaire survey on the members of companies that introduced the self management organization method and confirmed the appropriateness of the research model and the adoption of the research hypothesis. Next, we analyzed the effect of leadership on employee satisfaction and then confirmed the effect of employee satisfaction on customer satisfaction. 본 연구는 경영환경이 불확실한 상황에서 Holacracy(자율경영조직) 관련 이론적 배경을 토대로 연구모델을 구축하고 실증분석을 실시하는데 있다. 특히, 본 연구는 자율경영조직 방식을 도입하고 있는 기업의 구성원들을 대상으로 설문조사를 실시하여 연구모형의 적합성과 연구가설의 채택 여부를 확인하였다. 이어, 리더십이 종업원 만족에 미치는 영향관계를 분석하고 이어 종업원 만족이 고객만족에 미치는 영향을 확인하였다. 자율경영조직 제도를 도입하여 실시하고 있는 기업들의 종사자들을 대상으로 설문지 204부를 수거하였다. 소표본 이고 정규분포 가정에 대한 엄격성이 덜한 PLS프로그램을 통해서 분석한 결과, 자율경영 리더십이 종업원 만족에 에서 유의한 영향을 미치는 것으로 나타났다. 또한, 종업원 만족은 고객만족에 에서 유의한 영향을 미치는 것으로 나타났다. 자율경영조직에 대한 자율경영 리더십이 자율경영조직 성패를 가르는 결정요인이라고 할 수 있다. 이는 종업원 만족으로 이어져 조직 가치창출의 원천이라 할 수 있는 고객만족을 높이는 핵심결정 요인임을 알 수 있다.

유병대,이명갑,서영조,조준,박찬상,이동필 대한응급의학회 2000 대한응급의학회지 Vol.11 No.4

Background: The differentiation between hemorrhagic(HS) and norhemorrhagic(NHS) stroke is the most important first step in the management of acute stroke because clinical management of the two disorders differs substantially. Neuroimaging studies are useful in diagnosing and distinctioning between HS and NHS. The use of clinical variables, such as Siriraj stroke scores(SSS), has led to good sensitivity, specificity and predictive values. The aim of our study was to evaluate the use of the SSS in the Korean population and assess whether it could aid to expedite treatment decisions. Methods: We reviewed 111 cases of stroke patients admitted to our hospital via the emergency department over a 6 months period from July to December 1998. Levels of consciousness, vomiting, headache, and atheroma markers used in the SSS were applied to these patients who met the criteria for a stroke. Results: Of the 111 patients, the SSS classified 83 with sensitivities of 81.1%(NHS) and 73.3%(HS) and positive predictive values of 84.3% and 68.8%, respectively. The overall accuracy rate was 78.3%. Conclusion: Our results suggest that the SSS is not reliable in distinguishing stroke types in the Korean population. Definite neuroimaging studies are needed prior to thrombolytic therapy.

유병대,김성진,이명갑,서영조,강재구,이동필 대한응급의학회 2000 대한응급의학회지 Vol.11 No.4

Background: Good documentation of electrical injuries at the time of presentation is very important to emergency management, so this study was designed to investigate the clinical characteristics and the outcomes of patients with electrical injury. Methods: A review of 75 cases of electrical injuries admitted to our hospital via the emergency department over a 4 year period from 1996 to 1999 was conducted. Results: There were 49 patients with high-voltage injuries and 19 patients with low-voltage injuries. All but 4 patients were males, with a mean age of 29.5 years. The most common type of injury was electrothermal burn. The most common point of entry was hand. The average size of burn wounds was 14.5% TBSA in the high-voltage group and 2.5% in the low-voltage group. Forty-nine(72.1%) of the injuries were work related. The number of patients with compartment syndrome was 19, and fasciotomies were performed in all but one patient. Myoglobinuria was noted in 22 patients, but no patient developed acute renal failure due to myoglobinuria. In the high-voltage group, 10 limb amputations were performed. Complication were observed in 12 patients. The most common complication was neurological injury. The average length of hospital stay was 50.7 days in the high-voltage group and 13.8 days in the low-voltage group. The overall mortality rate was 4.3%. Couclusion: Prevention of electrical injuries is very important. Education and compliance with safety measures, as well as basic knowledge and precaution in dealing with electricity, are essential to avoid these injuries.

인슐린비의존성 당뇨쥐에서 심방이뇨호르몬 농도와 mRNA 변동

유병대,박원균,홍영수,송대규,배재훈 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.24 No.4

연구배경:신생 흰쥐에서 streptozotocin(STZ)으로 유도한 인슐린 비의존성 당뇨병( NIDDM )모델의 흰쥐를 대상으로 ANP의 혈중 농도의 변동과 심장, 시상하부 및 신장의 ANP 합성의 변동을 관찰하여, 당뇨병에서 발생될 수 있는 체액 및 전해질 불균형에 대한 ANP의 조절기능을 규명하고자 하였다. 방법: NIDDM 쥐(당뇨군)는 생후 1∼2일된 Sprague­Dawley종 수컷 흰쥐에 citrate buffer에 녹인 STZ(80㎎/㎏)을 등쪽에 피하 주사하여 유도하였다. 같은 날 STZ이 없는 동량의 cirtrate buffer만을 투여한 쥐를 대조균으로 하였다. 혈장 ANP 농도는 STZ을 투여한 8주 후에 대동맥을 통해 채혈한 뒤 방사면역법으로 측정하였다. ANP 합성단계의 병동을 파악하고자 우심방, 좌심실, 시상하부 및 신장의 피질부위를 채취하여[³²P]­dCTP를 이용한 역전사­중합효소연쇄반응을 시행하여 ANP mRNA의 변동을 관찰하였다. 결과:생후 7주에 시행한 당부하시험에서 공복시 혈당치는 당뇨군과 대조군사이에 차이가 없었고, 당뇨군에서는 glucose주입 후 30분후에 혈당치가 크게 증가 하였으며 2시간 뒤에도 계속 증가하여 유지되었다. 생후 8주에 당뇨군이 대조군에 비해 체중은 약간 감소, 수분 섭취량은 증가하는 경향이 있었다. 혈자 ANP 농도는 당뇨군에서 대조군에 비해 유의하게 증가하였다. ANP mRNA 발현의 정도는 조직에 따라 차이가 있었다. 당뇨군의 ANP mRNA 발현은 대조군에 비해서, 우심방에서는 약간 증가하는 경향이 있었고, 좌심실에서는 양군사이에 거의 동일한 값을 보였다. 반면에 시상하부와 신자의 피질에서는 당뇨군이 대조군에 비해 ANP mRNA 발현이 유의하게 증가하였다. 결론:신생 흰쥐에 streptozotocin으로 유도한 NIDDM 모델에서 관찰한 ANP mRNA 변동의 결과로 보아, ANP가 이미 알려진 심방이외 신장 및 시상하부에서 ANP 합성의 증가를 통해 NIDDM에서 세포 외액량과 전해질 균형의 조절에 중요한 역할을 담당하는 것으로 생각된다. Background : Diabetes mellitus has led to change in fluid and electrolyte balance and consequently affected blood volume and blood pressure. These changes can trigger the secretion and synthesis of atrial natriuretic peptide (ANP) from both atrial and extra-atrial tissues. ANP plays an important role in the regulations of body-fluid balance and blood pressure. Therefore, this study was carried out to elucidate whether of not atrial and extra-atrial synthesis of ANP is influenced in experimental non-insulin dependent diabetes mellitus (NIDDM) rats. Methods : Neonatal rats were induced into NIDDM rats by single injection of streptozotocin (80 ㎎/㎏). Plasma ANP level was measured by the use of radio immunoassay method and the ANP m RNA expressions from the right atrium, left ventricle, hypothalamus and kidney were analyzed by reverse transcription-polymerase chain reaction with [32^P]-dCTP at 8 weeks after injection of streptozotocin or citrate buffer. Results: Blood glucose was more significantly increased at 2 hours after glucose loading in NIDDM rats than control rats. Plasma concentration of ANP tended to significantly increase in NIDDM rats compared with control rats. The expressions of ANP m RNA from each tissue were observed in different patterns. Right atrial ANP m RNA expression revealed non-significant increeasing trend in NIDDM rats, where as left ventricular ANP m RNA expressions in NIDDM rats were significantly increased. Conclusion : These results indicate that the enhanced expressions of hypothalamic and renal ANP m RNA actasan important regulator of electrolytes and body fluid volume in neonatally streptozotocin-induced NIDDM rats(J Kor Diabetes ASSO 421~430, 2000).

오후진,유병대 공주대학교 사범대학 과학교육연구소 1998 과학교육연구 Vol.29 No.1

확률·통계는 일상생활, 자연과학, 사회과학과도 깊이 관련된 수학의 중요한 한 분과로 자리매김을 하고 있다. 이러한 중요성에도 불구하고 이를 배우는 학생들의 경우 초·중·고교의 단계를 높일수록 어려워하고 대학수학능력시험에서 확률·통계가 차지하는 비중이 미미하다는 이유로 아예 포기하는 경우가 허다하다. 따라서, 초·중·고교의 교육과정 및 교과서의 연계성을 면밀히 분석하여 문제점 및 개선방향 등을 알아봄으로써 효과적인 지도방법을 강구할 필요가 있다. 본 연구는 현행 초·중·고등학교 확률·통계 분야의 실태를 분석하여 효율적인 지도방법을 제시함으로써 학생들의 확률·통계에 대한 자신감, 흥미, 성취동기를 심어주고 수학적 사고를 길러 합리적이고 창의적인 의사결정을 하도록 하는 데 그 목적이 있다. 본 연구는 Ⅱ장에서의 이론적 배경을 토대로 Ⅲ장에서 초·중·고등학교별로 수학교육과정 및 교과서의 확률·통계 지도의 의의, 내용개요, 지도상의 유의점, 문제점 등을 살펴보고 효과적으로 지도할 수 있는 구체적인 방법을 제시하고 Ⅳ장에서는 결론으로 전반적인 확률·통계 교육의 개선 및 지향 방향을 알아보도록 한다. probability and statistics is an important section in mathematics which is deeply related to everyday living, natural science and social science. In spite of its importance, many students will throw away it because it becomes very harder as its step(stage) deepens and probability and statistics' relative importance is very small in Korea-SAT(the test of college entrance in Korea). Therefore, by analyzing the involvement carefully between the curriculum in the elementary, middle, high school and the text book, by studying the problem and improvement direction, it is necessary to investigate an effective teaching method. This study intends to give the students the confidence, interests, and accomplishment motive about probability and statistics field and to make a rational and creative decision-making through mathematical speculation by proposing an effective teaching method through analyzing an existing facts in school's probability and statistics field. The contents of this study are composed of four chapters. Chapter three looks into the mathematical curriculum in the elementary, middle, high school and its teaching meaning, the outline of contents, some tips on teaching and problems and presents an effective and concrete teaching method on the basis of the theoretical background in the chapter two. Chapter four is a conclusive part and gives the general improvement and intentional direction in educating the probability and statistics.
