We report an extremely rare case of traumatic cervical spinal subdural hematoma not related to intracranial injury. There has been no report on traumatic cervical spinal subdrual hematoma not related to intracranial injury. A 27-year-old female patient was admitted to our emergency room due to severe neck pain and right arm motor weakness after car collision. On admission, she presented with complete monoplegia and hypoesthesia of right arm. Magnetic resonance imaging (MRI) revealed subdural hematoma compressing spinal cord. Lumbar cerebrospinal fluid (CSF) analysis revealed 210,000 red blood cells/$mm^3$. She was managed conservatively by administrations of steroid pulse therapy and CSF drainage. Her muscle power of right arm improved to a Grade III 16 days after admission. Follow-up MRI taken 16th days after admission revealed almost complete resolution of the hematoma. Here, the authors report a traumatic cervical spinal SDH not associated with intracranial injury.

We investigated and analyzed students' perceptions of their choice of science subjects in the high school credit system and the reasons for their choice. To achieve this, the selection of science subjects was investigated for the second year of S high school over the past three years. Students selected an average of 1.54 science subjects, and it was found that the rate of selection of science subjects was gradually increasing by year. Students chose high in the order of life science I, earth science I, chemistry I, physics I, etc. in the science subject group. Students who wish to enter the natural and engineering fields chose life science I, chemistry I, physics I, etc., while, students who wish to enter the humanities society chose society and culture, life science I, ethics and thought, etc. On the other hand, the reason for choosing science subjects was 'related to college admission', followed by 'aptitude and interest', 'career and real life help', etc. physics I, chemistry I, etc., were high in the subjects selected according to the 'related to college admission'. The subjects selected according to 'aptitude and interest' were high in life science I, earth science I, etc. Physics I, chemistry I, etc. are recognized as subjects necessary for college entrance, and life science I, earth science I, etc., are found to be related to their interests and aptitudes.

This study was conducted to investigate whether variations in hospital services utilization across small geographic areas in Korea existed, and if so, what factors are responsible for the variation. The claims data of the fiscal year 1992 obtained from the regional health insurance societies were used for the study. Main findings of the research can be summarized as follows: 1 Extremal Quotients (EQ) of hospital expenditure per capita and hospital days per capita were 2.69 and 2.73, and Coefficient of Variation (CV) were 0.14, both, respectively. The EQ and the CV of admission rate were also 2.71, 0.15. The EQ and the CV of expenditure per admission were 1.73, 0.10 and those of hospital days per admission were 1.29, 0.06. All these statistics were statistically significant and this result provides strong evidence for the existence of small area variations. 2. Comparing patterns of variation among areas, the area which showed higher utilization amounts is Chansungp'o. Koje area, whereas the areas which showed lower utilization amounts are Yongju, Changhung, Miryang, Mokp'o, Koch'ang area. 3. Multivariate analytic methods were used to examine factors related to the variation across areas. In terms of the health resource availability variables, beds per capita or physicians per capita were positively associated with all utilization indices. As for the health service market structure variables, the proportion of health care institutions operating for less than f years was positively related to the expenditure per capita, hospital days per capita and expenditure per admission. In addition the proportion of the private health care institutions also had a negative relationship with total utilization amount and admission rate and the proportion of physicians under age 40 was negatively associated with expenditure per capita and expenditure per admission. With regard to the socio-demographic characteristics, proportion of medicaid population was positively related to hospital days per capita, and percentage of paved road was positively related to hospital days per admission. As a conclusion, wide variations existed across small areas in Korea and supply factors were found to be important in explaining the variation.

Influenza virus is a major cause of respiratory infection in the epidemic season. Especially, the elderly with underlying health problems are at increased risk for complications of influenza. The objective of this study was to investigate that influenza vaccination can reduce the hospital admission rate related to the respiratory diseases. This study was a retrospective study of two age groups, who are the healthy children aged 6 months to 9 years (n=237) and the adults aged over 20 years with respiratory disease (n=327). The vaccinated groups were compared to the controls that were matched in sex and age. The children were vaccinated in winter season of 1995-96 and the adults were vaccinated in 1996-97. The efficacy of influenza vaccine was evaluated with the number of outpatient visits in children group, the admission rate and the mean admission days in both children and adult group. As results, there were not significant differences between the vaccinated and the control group of children. In the elderly over 61 years, however, the influenza vaccination can reduce the admission rate $(8.9\%\;vs.\;25.6\%,\;p<0.05)$ and the mean admission days (1.3 vs. 3.8 days, p<0.05) compared to the control. In conclusion, influenza vaccination can effectively reduce the events related to respiratory infection in the elderly than the children. The elderly should be recommended for influenza vaccination.

대입제도와 관련된 논쟁 중 하나는 수시전형과 정시전형 중 어느 입학전형이 사회적 계층이동을 위한 기제로서 작동하는지에 대한 것이다. 본 연구는 한국교육고용패널조사 II(KEEP II) 데이터의 3차년도 자료를 활용하여 입학전형(수시전형 vs 정시전형)에 따른 대학입학생들의 소득수준을 분석하여 관련 논의에 기여하고자 하였다. 3차년도 자료 분석결과 일반대학에 입학한 학생들 전체적으로는 정시와 수시 입학생들 간의 부모소득은 거의 유사한 것으로 나타났다. 정시는 585.4만원 수시는 586.4만원으로 수시전형 입학생이 월평균 부모소득이 1만원이 더 높은 것으로 나타났는데 실용적으로나 통계적으로는 의미가 없었다. 다음으로 카이제곱검정을 통해 부모소득과 정시/수시입학유형 간의 관계를 분석한 결과 역시 통계적 유의성이 없는 것으로 나타났다. 그러나 대학순위그룹별로 분석한 결과 전반적으로 상위권 대학으로 갈수록 입학생들이 부모소득수준이 높아지는 것으로 나타났으며, 특히 본 연구의 주제인 입학전형별로 보면 정시전형 입학생들보다 수시전형 입학생들의 월평균 부모소득이 더 높은 것으로 나타나고 있었다. 따라서 수시(학종)전형이 상대적으로 더 금수저 전형일 가능성이 높음을 보여주며, 정시수능전형보다 사회적 계층이동을 원활히 하는 통로로서 작동하고 있지 못하고 있는 것으로 보는 것이 더 합리적인 판단으로 보인다.

The primary purpose of this study was to develop a college adjustment program for freshmen through admission officer system that relies less on test scores and on the various talents evaluated by admissions officers. To help these talented students adjust the new life of the university and enhance their gifts, a college adjustment program was developed with their special needs and characteristics. For that, the survey with 57 students and in-depth interviews with 12 students were conducted. The results revealed that the students wanted to learn study skills, self-management, global mind setting, and life vision and goals setting. Most of the students were worried about their grades because they entered the school with their talents and experience in diverse activities not SAT scores. To promote their academic performance, this program consisted of an academic readiness program which complements students' abilities in primary subjects like math, English, and science, and a potential progress program which is peer-group learning communities based on their own interests like global learning communities, creative learning communities, and service-learning communities. This program was suggested in the context of Comprehensive Development Model. To carry out the program systematically, related organizations and colleges should collaborate with each other.

Objective : Hydrocephalus is a common sequelae of aneurysmal subarachnoid hemorrhage (SAH) and patients who develop hydrocephalus after SAH typically have a worse prognosis than those who do not. This study was designed to identify factors predictive of shunt-dependent chronic hydrocephalus among patients with aneurysmal SAH, and patients who require permanent cerebrospinal fluid diversion. Methods : Seven-hundred-and-thirty-four patients with aneurysmal SAH who were treated surgically between 1990 and 2006 were retrospectively studied. Three stages of hydrocephalus have been categorized in this paper, i.e., acute (0-3 days after SAH), subacute (4-13 days after SAH), chronic (${\geqq}14$ days after SAH). Criteria indicating the occurrence of hydrocephalus were the presence of significantly enlarged temporal horns or ratio of frontal horn to maximal biparietal diameter more than 30% in computerized tomography. Results : Overall, 66 of the 734 patients (8.9%) underwent shunting procedures for the treatment of chronic hydrocephalus. Statistically significant associations among the following factors and shunt-dependent chronic hydrocephalus were observed. (1) Increased age (p < 0.05), (2) poor Hunt and Hess grade at admission (p < 0.05), (3) intraventricular hemorrhage (p < 0.05), (4) Fisher grade III, IV at admission (p < 0.05), (5) radiological hydrocephalus at admission (p < 0.05), and (6) post surgery meningitis (p < 0.05) did affect development of chronic hydrocephalus. However the presence of intracerebral hemorrhage, multiple aneurysms, vasospasm, and gender did not influence the development of shunt-dependent chronic hydrocephalus. In addition, the location of the ruptured aneurysms in posterior cerebral circulation did not show significant correlation of development of shunt-dependent chronic hydrocephalus. Conclusion : Hydrocephalus after aneurysmal subarachnoid hemorrhage seems to have a multifactorial etiology. Understanding predisposing factors related to the shunt-dependent chronic hydrocephalus may help to guide neurosurgeons for better treatment outcomes.

Background: Functional capacity evaluations (FCEs) are designed to systematically assess the capacity to perform work-related tasks and to determine worker's ability to return to the previous job following work-related injuries. These evaluations may be rated either by clinician or worker. There has been a lack of consensus between the two scoring methods. Objects: This study aimed: 1) to confirm if the data are fit to the Rasch rating scale model and 2) to investigate the item-level concordance rate between the ratings of clinician and injured worker of the FCE. Methods: A cross-sectional study was conducted with a sample (n=124) of a rehabilitation program with the Occupational Rehabilitation Data Base for workers with low back pain. The functional capacity evaluation at admission and discharge was administered to clinicians and workers. The data were analyzed using both classical test theory-based Pearson's r and intra-class coefficient followed by item-level analysis with Rasch rating scale model. Results: All items of the FCE, except sitting items rated by clinician at admission and handling items rated by both clinician and worker throughout admission and discharge, were acceptable fit statistics with minor out of ranges for a misfit criterion. This may indicate that the items of the FCE overall fit to the Rasch rating scale model. Few problematic items responding differently to clinician and worker both at admission and discharge were detected with the differential item functioning analysis despite the excellent concordance rate using the two conventional statistics-sitting and handling items at admission and handling item at discharge. Conclusion: The item-level speculations using Rasch analysis of the FCE demonstrate that the ratings of clinician and self ratings of worker were psychometrically acceptable though there was an apparent discrepancy between the raters both at admission and discharge.
