The droplet behavior of 83.9 wt.% HAN water solution was investigated experimentally with various ambient temperature and nitrogen environment. At the initial stage of evaporation under thermal decomposition temperature of HAN, gradual decreasing of droplet diameter was observed. After that, the droplet started to expand due to the internal pressure build up by water nucleation inside the droplet. The micro explosion was observed at higher temperature than the decomposition temperature of HAN and the remaining droplet showed similar behavior of single composition droplet. The decreasing rate was augmented as the ambient temperature increasing.

Poet, Huh, Young-ja, started her career of writing poems through 「The Modern Literature」 in 1962. From that time on, she has consolidated her writing career of 40 years by publishing 7 collections of poems. The 7 books have maintained even levels and consistent themes and methods so that they show the distinct quality of her own, which places her as one of the important poets of this country. This thesis divide the contents and methods Huh, Young-ja has relied on under four heads of 1. fierceness of disciplining the subject, 2. the ecstasy and sympathy in life, 3. the projection of the cognizance for the real, and 4. the dynamic imagination and manifestation of being. The items of No.1, 2, and 3 deal with the aspects of the contents and 4 those of methods. The approach taken by this thesis is based upon the fact that above-mentioned qualities are almost constitutional to Huh, Young-ja Therefore-instead of dividing the phases of the poet's poetic history, this thesis focuses on grasping the consistent world of the poet's consciousness represented in her whole texts. This type of analysis is encouraged by the theory of the Genevan School that says the in-depth reading of many collected peers of a poet shows that it has just one voice and the individual text is not an autonomous entity but a piece of the writer's literary experiences. This thesis is proceeded under the premise that the total poetic world of a poet can be exposed, when a piece of poetry has the dialogical relations with his or her other poems.

The effect of reducing flood magnitudes, flood stages, and flood damage by upstream reservoir regulation are investigated in this study. The analytical procedures which has been established newly, are treated through this study for 7 index stations and same numbr of reaches. The method of this study could be expressed briefly as following procedures. Using stage-frequency relations and the potential damage survey data, damage-frequency relations are established, and from this, average annual flood damages computed. By holding out portions of the floods with various amounts of flood control storage in 6 reservoirs in the basin, routing were made to establish modified stage-frequency relations. From damage frequency relation, average annual damages are computed with and without condition of each control volume. The study result are concluded as follows; (1) The relationtship of corresponding water level between nearby stations are useful tools to adjust error of the data due to observation error and change of the gaging location. (2) The number of records about 10 years could not be applied for the statistical methods of flood frequency analysis. (3) The regional skew factors are recommended to apply flood frequency study by the log-Pearson Type III method. (4) The effect of damage reductions are greatly affectedin accordance with the routed flood. Therefore application of the Typical Tributary Contribution Flood are reasonable for this type of study. (5) In the North Han, effect of damage reduction due to the lacation of control point are gradually increased from upstream to downward until the confluence of North and South Han. (6) In the South Han, control effect are increased from Chungju to Yeoju where the maximum effect are analyzed and then decrease gradually until the confluence. (7) Better hydrologic and topographic combinations for the flood control are existed in South Han to compare with North Han in this study results.

Background/Aims: Recent epidemiologic studies have shown a continued increase in colorectal cancer incidence among younger adults. Little is known about the factors that contribute to the development of young-onset colorectal neoplasia (CRN). Methods: A cross-sectional analysis was performed for individuals younger than 40 years who underwent colonoscopy in Seoul St. Mary’s Hospital and its affiliated health screening center. High-risk CRN was defined as adenoma or sessile serrated lesion ≥ 10 mm, with three or more adenomas, villous histology, high grade dysplasia, or carcinoma. Results: Of these 13,621 included participants, 2,023 (14.9%) had one and more CRN. Young patients with CRN tended to be elderly, male, obese, smoker, having a habit of drinking, and having comorbidities such as hypertension, dyslipidemia, diabetes, and chronic kidney disease. In a multivariate analysis adjusted for age, sex, obesity, smoking status, and alcohol intake, old age (odds ratio [OR], 1.086; 95% confidence interval [CI], 1.054 to 1.119), male sex (OR, 1.748; 95% CI, 1.247 to 2.451), obesity (OR, 1.439; 95% CI, 1.133 to 1.828), and smoking (OR, 1.654; 95% CI, 1.287 to 2.127) were independent risk factors for overall CRN. Obesity and smoking as two modifiable factors increased the risk for high-risk CRN even more than for overall CRN (OR, 1.734; 95% CI, 1.168 to 2.575 and OR, 1.797; 95% CI, 1.172 to 2.753, respectively). Conclusions: Obesity and smoking were modifiable risk factors for CRN in young adults. They increased the risk for highrisk CRN even more than for overall CRN. A colonoscopy might be beneficial for young individuals with these factors.

Purpose: Immediate identification of vascular injury requiring embolization in patients with pelvic bone fracture isn’t an easy task. There have been many trials finding indicators of embolization for patients with pelvic bone fracture. Although Young and Burgess classification is useful in decision making of treatment, it is reported to have little value as indicator of embolization in major trauma patients. The aim of this study is to find out Young and burgess classification on predicting vessel injury by analzyng pelvic radiograph taken from major trauma patients with pelvic bone fracture. Methods: Among major trauma patients with injury severity scores (ISS) higher than 15 who visited our emergency room from January 2011 to June 2014, 200 patients were found with pelvic bone fracture in trauma series and thus pelvic CT angiography was taken. Setting aside patients with exclusion criteria, 153 patients were enrolled in this study for analysis of Young and Burgess classification. Results: The most common mechanism of injury was lateral compression in both groups. There was no statistical significant difference in Young and Burgess classification (p=0.397). The obturator artery was the most commonly injured artery in both groups. Six patients had more than one site of bleeding. Conclusion: Prediction of transcatheter angiographic embolization using Young and Burgess classification in severe trauma patients is difficult and requires additional studies.

한국(韓國)의 문화(文化) : 문화로 읽는 근대 이행기 매체문학 -『년한반도(年韓半島)』를 대상으로-

문선영 ( Tae Moon Han ),한태문 ( Sun Young Moon ) 한국사상문화학회 2010 韓國思想과 文化 Vol.51 No.-

이 논문은 한국의 근대 매체인 『少年韓半島』를 통해 한국 근대 이행기 매체문학의 정체성을 살펴보려는 의도 아래 기획 집필된 것이다. 이 때 중심되는 화두는 `문화`이다. 근대 이행기를 배경으로 한 매체문학을 대상으로 당대 문화 풍속도를 고찰하고자 하였다. 『少年韓半島』는 1906년 11월 1일 창간되었고, 1907년 4월 통권 6호로 종간되었다. 『年韓半島』는 국민정신을 함양하고 신지식을 선도하는 데 발간 목적을 두었다. `민주 정체(民主 政體)`를 새로운 국가상으로 삼고 있으며, 국민의 자질을 갖추기 위해서 무엇보다 `지식`의 습득이 우선되어야 함을 강조했다. <『少年韓半島』와 문화의식>은 `문화` 코드를 중심으로 한국 근대 매체의 정체성 문제를 집중적으로 다룬 것이다. 연구 대상이 『少年韓半島』인만큼, 문화의 범주로는 아이 또는 청소년들을 중심으로 한 일상문화와 기저문화에 주목했다. 여기서 당대 소년들의 삶의 동선과 민족주의 그리고 계몽주의를 통해 당대 문화의식을 도출하였다. 무엇보다 `교육`에 방점을 둔 문화적 풍속도가 두드러진다. 『少年韓半島』는 근대 학지(學知)를 다양하게 소개함으로써 아이들에게 삶의 좌표 설정과 문화적 판도를 깨우치게 하고, 나아가 이후 발간되는 『소년』, 『청춘』 등 본격적인 아동 또는 청소년 잡지의 시대를 연 종합지로서 의의를 지닌다. 그러나 이제껏 『少年韓半島』의 원본이 공개되지 않아 본격적인 연구가 이루어지지 못한 학계의 사정을 감안할 때, 본고는 되도록 그 낱낱을 헤아리려 했다. `신대한(新大韓)` 또는 `신대한을 건설할 주체`의 표상으로 `소년`을 전면에 내세우고 있는 만큼, 이를 중심으로 근대이행기의 문화 풍속 담론의 정체성을 해명하는 데 바쳐져 있다. This paper was written in the purpose of examining the identity of the media literature in the transitional period to modern ages in Korea by The Boy Han Peninsula. The topic of discussion is "culture." This paper tries to reflect on the cultural manners and customs in those days making the media literature which are based on the transitional period to modern ages as the object. The Boy Han Peninsula was launched on 1 Nov 1906 and ceased to be published in April of 1907, totally making 6 volumes. It was published in order to cultivate the spirit of the nation and lead the new set of knowledge. It takes the `political body of democracy` as the new portrait of the country, and emphasized that the learning of `knowledge` must be preceded for the preparation of the capabilities of the nation. `The Cultural Consciousness Appearing in The Boy Han Peninsula` focusedly dealt with the problem of the identity of media in modern Korea, mainly by the code of `culture`. As its title suggests, its cultural category directs its attention to the culture of ordinary lives of children and juveniles and their subculture. It induces the cultural consciousness of those days by those predicates of the lives of the boys of those days, nationalism and illumine. The cultural manners and customs of those days is especially marked by its drive toward education. The Boy Han Peninsula introduced various academic knowledge of modern times to awaken the children to the problem of setting proper coordinates in their lives and to the cultural territory of those days, and performed its role of pioneers who opened up the era of child or juvenile magazines which successively followed up like Boy, Youth and others. As its research object is The Boy Han Peninsula, before anything else, this paper is dedicated to explain the identity of the literary history of the modern ages in Korea as a discourse on the cultural manners and customs of the transitional period to modern ages by reflecting on the cultural manners and customs of that transitional period to modern ages, mainly by children that `Purpose` in the first volume makes `boyhood` stand for, or the symbol of the leader who will establish, the New Great Han.

Objectives : As the elderly population is continuing to increase, psychiatric diseases of the elderly are becoming an important social issue. This study looks into the demographical and clinical features of the elderly patients diagnosed with bipolar disorder in a University hospital. Methods : The study subjects include patients admissioned in the closed wards of Soonchunhyang Seoul hospital and Cheonan hospital from March, 2000 to February, 2005 who met the DSM-IV-TR criteria for bipolar disorder at the time of discharge. A total of 146 patients (76 men, 70 women) medical records were studied retrospectively. Subjects older than the age of 50 at time of admission were grouped as the old age group, whereas those who were younger than 50 as the young age group. Also among the old age group, those who had the first onset of episode under the age of 50 were grouped as the early onset group, whereas those who had the first onset after the age 50 were grouped as the late onset group. Results : The number of bipolar disorder patients in the young age group and old age group were 73 and 73 respectively. The number of early onset group and late onset group were 46 and 23 respectively. The old age group had a relatively higher incidence of bipolar II disorder than the young age group. Also in the old age group there was a higher incidence of hypomanic or depressive episode rather than manic episode compared to the young age group. And in the old age group psychotic symptoms were less common and the mean admission length shorter than the young age group. Additionally in the old age group treatment with Lithium monotherapy or with no mood stabilizers at all were relatively common. Among the old age group, late onset group had a higher rate of bipolar II disorder than the early onset group. Conclusion : This study shows differences in the demographical and clinical features among different age groups. But additional research would be required to determine whether the bipolar disorders in the elderly or late onset group are actually a different type of disorder from those of the young.

Background/Aims: Inflammatory diseasas of the pancreas are not uncommon. The advanced age is one of the significant factors in assessing the severity of acute pancreatitis. It has been shown that the biliary tract disease is a more frequent cause of acute pancreatitis in the elderly than in the young. With the increased life span, the elderly are comprising a large proportion of the population. As a result, physicians are more often being faced with acute pancreatitis in the elderly. The purpose af this study was to evaluate clinical features of acute panereatitis in the elderly. Methods: A total of 188 patients with acute pancreatitis were reviewed. We investigated the differences of clinical characteristics between the elderly patients aged over 60 and the young patients aged under 60. Results: The sex distribution showed male preponderance in the young patients (M:F=2.4:1), but was nearly equal in the elderly patients (M:F=1.1:1). The most common cause of acute pancreatitis in the elderly was biliary tract disease (52.5%), while alcohol abuse was the most common cause in the young patients (38.8%), Local complications of acute pancreatitis, such as psuedocyst, necrosis, abscesses were not differently shown between the elderly (16.9%) and the young (20.2%) patients. Systemic complications including acute puhnonary failure occurred more frequently in the elderly patients than the young patients. The mortality rate of the elderly patients (5.1%) was not significantly different from that of the young patients (3.1%). Conclusions: To detect correctable underlying bihary tract diseases the elderly patients with acute pancreatitis should be completely investigated using endoscopic retrograde cholangiopancreatography (ERCP). In addition, the patient should be closely monitored for the development of the systemic complications during the disease process.
