Consumers get information about products through rates like SNS, as consumers can not actually touch or see products online and they are important marketing information for firms. Opinion Mining is used to analyze the information. English Positive-Negative words dictionaries, such as WorldNet-Affecct, SentiWordNet are used in Opinion Mining, however, there are no Korean dictionaries. Dictionaries could be complied by hand, but it would take lots of time and costs. The paper solved the problem of SO-PMI(Semantic Orientation from Point-wise Mutual Information), used to classify the polarity of vocabularies, and suggested the way how to classify the polarity by considering characteristics of products. New SO-PMIs performance improved by 9%, when not reflecting characteristics and by 18%, when considering them, compared to the existing SO-PMI.

목적: 최근 midazolam을 이용한 상부 소화관 수면 내시경법이 널리 시행되고 있으나 피검자에 따라 midazolam 투여에 따른 진정효과 및 수면 내시경을 시행 받은 후 만족도가 다르다. 이에 저자들은 midazolam의 적절한 투여용량 및 투여용량에 영향을 미치는 인자를 알아보고, 검사 후 그 길항제인 flumazenil의 적절한 투여시기에 대해 연구하였다. 방법: 상부 소화관 수면 내시경을 시행한 126명의 피검자를 대상으로 투여된 midazo Background: Intravenous administration of midazolam is widely used as a premedication for esophagogastroduonenoscopy. However, there are individual differences in midazolam doses for premedication and controversies for starting point of esophagogastroduon

배 경 : Neopterin은 γ-인터페론의 자극하에 주로 단핵세포와 대식세포에서 생성되는 pyrazino-pyrimidine 화합물로서 세포면역이 활성화된 상태를 나타낸다. 세포면역 기전이 매개가 되는 장기이식의 거부반응, 감염질환, 자가면역질환, 종양 및 심부전이나 신부전 등 여러 질환에서 증가하며 진단 및 예후의 지표가 된다고 알려져 있다. 특히 신질환에서 neopterin치 측정이 세포면역의 활성도를 나타내는데 유용하다고 알려져 있으나 전반적인 신질환과 neopterin와의 연관성온 정확히 알려져 있지 않다. 이에 저자들은 신증후군, 만성 신부전 및 말기 신부전으로 유지혈액투석을 받고 있는 신장질환 환자들에서 혈청 및 요 neopterin치를 측정하여 신장질환과 neopterin과의 연관성을 알아보고, neopterin과 다른 임상적인 표지자들과의 상관관계를 알아보아 neopterin치 측정의 임상적 유용성을 평가하고자 하였다. 방 법 : 총 91명 환자 (신장조직검사로 확진된 신증후군 19명, 만성 신부전 8명, 말기 신부전으로 유지혈액투석 중인 환자 64명)에서 혈청 및 요 neopterin치를 radioimmunoaasay 방범으로 측정하였고 임상지표로는 WBC, hemoglobin, hematocrit, BUN, creatinine, total protein, albumin, triglyceride (TG), iron, total iron binding capacity (TIBC) 등을 측정하였다. 결 과 : 혈청 neopterin치는 신증후군, 만성 신부전, 말기 신부전 환자들에서 각각 14.1±30.9, 28.2±19.4, 65,6±25.5 ng/dL로 모두 대조군 1.6±0.3 ng/dL에 비해 증가하였고, 이중 만성 신부전과 말기 신부전 환자에서 통계적으로 의미있게 증가하였다 (p<0.05, p<0.01). 요 neopterin치 또한 신중후군, 만성 신부전, 말기 신부전에서 각각 203.2±349.6, 319.2±107.7, 407.9±256.9 μ㏖ neopterin/㏖ creatinine로 모두 대조군 108.9±57.9 μ㏖ neopterin/㏖ creatinine 보다 각각 증가하였고, 역시 만성 신부전과 말기 신부전에서 통계적으로 의미있게 증가하였다 (p<0.05, p<0.05). 전체 대상군에서 혈청 neopterin치와 임상적 표지자들과의 관계에서 혈청 creatinine과는 양의 상관관계를, triglyceride, TIBC와는 음의 상관관계를 보였고 (각각 p<0.01), 요 neopterin치는 hemoglobin과 음의 상관관계를 보였다 (p<0.05). 결 론 : 신증후군, 만성 신부전, 말기 신부전 등 몇 가지 신장질환 환자들에서 혈청 및 요 neopterin치의 증가와 neopterin치와 몇 가지 임상지표들과의 의미있는 연관성을 통하여 신장 질환 환자에서 neopterin치의 측정이 이들 질환의 활동성 및 예후의 한 지표로 이용될 수 있을 것으로 생각되며 이는 앞으로 보다 많은 수의 연구대상과 지속적인 후향적 연구가 필요할 것으로 생각된다. Background : Neopterin is a pyrazino-pyrimidine compound, produced by human monocytes or macrophages primarily upon stimulation with gamma in terferon. Neopterin is a marker associated with cell mediated immunity. The levels of neopterin in body fluids are elevated in allograft rejection, infections, autoimmune diseases, malignancies, cardiac and renal diseases. We hypothesized that the levels of serum and urine neopterin maybe elevated in some renal disease including nephrotic syndrome (NS), chronic renal failure (CRF) and end stage renal disease (ESRD). Methods : We examnined the serum and urinary neopterin levels in 19 patients with NS underwent renal biopsy, 8 patients with CRF, 64 patients with ESRD undergoing maintenance hemodialysis. Twenty-two healthy controls were enrolled to define the normal range of neopterin levels. Serum and urinary neopterin were measured by radiommunoassay method. We also correlated the levels of serum and urinary neopterin with many clinical parameters such as WBC, hemoglobin, hematocrit, BUN, creatinine, total protein, albumin, triglyceride, iron, total iron binding capacity. Results : The serum neopterin levels elevated in patients with NS (14.1±30.9 ng/mL), CRF (28.2±19.4 ng/mL) and ESRD (68.6±25.5 ng/mL) than control (1.6±0.3 ng/mL). Particularly the patients with CRF and ESRD showed statistically significant elevation (p<0.05, p<0.01). The urine neopterin levels elevated in patients with NS (203.2±349.6 μmol/mol creatinine), CRF (319.2±107.7 μmol/mol creatinine) than control (108.9±57.9 μmol/mol creatinine). Particularly the patients with CRF and ESRD showed statistically significant elevation (p<0.05, p<0.05). The serum neopterin showed significantly positive correlation with serum creatinine levels, inverse correlation with total iron binding capacity and serum triglyceride levels among clinical parameters in all groups (respectively p<0.01). The urine neopterin showed significant inverse correlation with hemoglobin (p<0.05). Conclusion : The serum and urinary neopterin levels elevated in patients with some renal diseases. And also neopterin levels showed clinical correlations with some renal parameters in these patients. We suggest that serum and urinary neopterin levels may be useful marker to predict disease acitivity and prognosis in some renal diseases. They should be confirmed by a prospective study during a long-lasting and in a higher number of patients. (Korean J Nephrol 2004;23(2):241-247)

Purpose: All-terrain vehicle (ATV)-related injuries have increased since the introduction of ATVs to Korea. The purpose of this study is to compare patients with ATV-related injuries (PATV) to patients with motorcycle (MC)-related injuries (PMC). Methods: We retrospectively analyzed the clinical records of PATV and PMC who visited an emergency center in 2008. The cases of PMC were 164, and those of PATV were 52. Results: While PMC are seen evenly in the first half year and the second half year, PATV are seen mainly the first half year (from March to June: 73%). For PMC the most frequent injury mechanism was collision with another vehicle, while for PATV, it was side overturn/roll over. The injury severity score (ISS), the revised trauma score (RTS), the trauma score and the injury severity score (TRISS) were 5.6±5.6, 7.7±0.7, 5.0±2.1 for PMC and 7.1±7.5, 7.7±1.1, 5.5±1.5 for PATV, respectively. The most common injury sites were the lower extremities for PMC and the face for PATV. The rates of admission, surgery and the length of hospital stay were similar between PMC and PATV. Conclusion: This study shows that the risk of ATV accidents is similar to that of MC accidents. We recommend that the same safety standards and regulations that are applied to MCs should be used for ATVs. Safe and enjoyable paths have to be sought for drivers of ATVs.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

Neck trauma can result in a spectrum of injuries and complications ranging from incidental to life threatening, including hemorrhagic shock, acute neurologic injury, and airway obstruction. A prevertebral hematoma associated with a cervical vertebra fracture is not a common condition, moreover, in such cases, airway obstruction is rare. If this condition occur, it may very fatal that can producing hypoxia, cyanosis, acidemia, hypoxic brain damage, and then death. For this reason, the attending physitian must careful observation and protect the airway until the hematoma is reduced and other complication relieved. Recently, we experienced a case of airway obstruction induced by cervical vertebra teardrop fracture (C5). the hematoma progressed slowly and then progressively; Finally it compressed the airway. So we present this case with a reviews of the literature.
