This study investigates the semantic types of cause expressions in mental counseling dialogues, drawing upon the “Target–Aspect” framework from sentiment analysis research. Employing a bottom–up approach, we analyzed web–scraped posts from the online platforms “Mindcafe” and “Wellness Conversation Scripts” from AI HUB and identified 24 target types and 24 aspect types. Subsequently, we validated our proposed typology by classifying cause expressions in 300 new dialogues, achieving an accuracy of 95.1% for target types and 92.6% for aspect types.

Objective There is a traditional assumption that to maximize stroke volume, the point beneath which the left ventricle (LV) is at its maximum diameter (P_max.LV) should be compressed. Thus, we aimed to derive and validate rules to estimate P_max.LV using anteroposterior chest radiography (chest_AP), which is performed for critically ill patients urgently needing determination of their personalized P_max.LV. Methods A retrospective, cross-sectional study was performed with non-cardiac arrest adults who underwent chest_AP within 1 hour of computed tomography (derivation:validation=3:2). On chest_AP, we defined cardiac diameter (CD), distance from right cardiac border to midline (RB), and cardiac height (CH) from the carina to the uppermost point of left hemi-diaphragm. Setting point zero (0, 0) at the midpoint of the xiphisternal joint and designating leftward and upward directions as positive on x- and y-axes, we located P_max.LV (x_max.LV, y_max.LV). The coefficients of the following mathematically inferred rules were sought: x_max.LV=α0*CD-RB; y_max.LV=β0*CH+γ0 (α0: mean of [x_max.LV+RB]/CD; β0, γ0: representative coefficient and constant of linear regression model, respectively). Results Among 360 cases (52.0±18.3 years, 102 females), we derived: x_max.LV=0.643*CD-RB and y_max.LV=55-0.390*CH. This estimated P_max.LV (19±11 mm) was as close as the averaged P_max.LV (19±11 mm, P=0.13) and closer than the three equidistant points representing the current guidelines (67±13, 56±10, and 77±17 mm; all P<0.001) to the reference identified on computed tomography. Thus, our findings were validated. Conclusion Personalized P_max.LV can be estimated using chest_AP. Further studies with actual cardiac arrest victims are needed to verify the safety and effectiveness of the rule.

The greatest improvement on the technological side was observed in IT literacy while ability to respond to changes was also increased. Besides, effects were demonstrated in behavioral factors such as initiative, spirit of challenge, experience, and openness. Lastly, the Capstone Design Education Program Learning Model was proposed in order to foster convergent talents in the fashion world.

지역사회획득 폐렴의 외래진료

김신우 대한내과학회 2011 대한내과학회지 Vol.81 No.5

지역사회획득 폐렴의 외래 치료는 국내에서 흔한 원인균인 S. pneumoniae에 대한 β-lactam 항생제와 macrolide 병용투여가 권장되고 있다. Macrolide 단독 투여는 국내 실정에서는 외국 가이드라인들과는 달리 macrolide 고도내성 S. pneumoniae로 인해 권장되지 않는다. β-lactam 항생제 단독투여와 β-lactam 항생제와 macrolide 병용투여의 비교 연구는 결정적 근거가 없으나 β-lactam 항생제 단독제제도 사용 가능할 것으로 가이드라인은 제시한다. 호흡기용 fluoroquinolone의 단독사용은 가능하나 결핵의 가능성이 있는 경우 1차 진료 시 사용하지 않는 것이 좋을 것으로 보이며 향후 내성 증가에 대한 관심이 필요하다. 흔한 원인균과 항생제 내성 등의 고려 외에 경험적 치료를 위해서는 기저질환과 연관된 원인균을 추가적으로 고려하는 것이 필요하다. 많은 지역사회획득 폐렴이 중증도가 높지 않은 경우 외래 치료가 가능하고 이에 대한 적절한 치료가 제시되어 있다. 이에 대한 근거중심의학적 권유(국내 가이드라인 및 외국 가이드라인 등)가 나와 있으며 가이드라인을 따를 때 좋은 예후를 보임은 잘 증명되어 있다. 그러므로 이에 대한 적극적인 적용이 확산되는 것이 필요하다.

김신우,박효정,오원섭,김연숙,장현하,정숙인,정두련,이혁,염준섭,기현균,손준성,백경란,우건조,송재훈 대한감염학회 2004 Infection and Chemotherapy Vol.36 No.6

Background:To evaluate the appropriateness of intravenous (IV) ciprofloxacin usage in university hospitals in Korea. Materials and Methods:We prospectively evaluated the appropriateness of drug usage in 290 consecutive adult patients who received IV ciprofloxacin in eight teaching hospitals during the period from September 25, 2003 to November 15, 2003. Drug use evaluation (DUE) in this study was based on the modified standard by the American Society of Hospital Pharmacy with regard to the justification of drug use, critical and process indications, complications, and outcome measures. Results:Average age of the patients was 54 years. The use of IV ciprofloxacin was appropriate only in 33 cases (26.9%). Common reasons for inappropriate use of IV ciprofloxacin include perioperative uses or prophylactic injection before urologic procedures, and empirical therapy for febrile episodes. Most of the "critical indications" and "process indications" showed high rate of appropriateness (82.4-100%). However, the rate of taking culture and sensitivity test before (73.8%) and during ciprofloxacin use (68.6%) were low. Complications with ciprofloxacin use were rare. In 93.3% of cases, ciprofloxacin treatment was clinically effective. Conclusion:Use of intravenous ciprofloxacin is frequently inappropriate in tertiary care hospitals in Korea. Implementation of education program and antibiotic control system is critical in improving the appropriateness of antimicrobial use. 목 적 : 국내 병원에서의 정주 ciprofloxacin 사용의 적정성을 평가하고자 하였다. 재료 및 방법 : 2003년 9월 25일부터 8개의 대학병원에서 정주 ciprofloxacin을 받았던 290명의 연속적으로 모집한 성인환자를 대상으로 약제사용 평가(DUE)를 전향적으로 수행하였다. 이 연구에 사용된 DUE 기준은 미국병원약사회의 기준을 국내 실정에 맡게 수정하여 사용하였으며 1) 사용의 정당성에 관한 항목, 2) 사용 시 준수되거나 시행되어야 할 사항에 대한 항목, 3) 부작용에 대한 항목, 4) 치료 효과에 대한 항목으로 나누어 조사하였다. 결 과 : 환자의 평균 나이는 54세였다. 33예(26.9%)에서만 약제 사용의 적정성 측면에서 기준을 만족하였고 91예(73.1%)에서는 사용이 적절하지 않았다. 정주 ciprofloxacin의 부적절한 사용의 흔한 원인은 수술 전후의 예방약 사용, 비뇨기계 처치 전의 예방적 사용, 열성 질환에 대한 경험적 사용 등의 순이었다. 사용 시 준수사항 의 측면에서는 사용 전 배양검사(73.8%)와 사용 중 배양검사(68.6%)가 낮은 수행 정도를 보였으나 그 외는 비교적 높은 적정성(82.4-100%)을 보여주었다. 정주 ciprofloxacin 사용의 합병증은 드물었다. 치료 효과의 면에서 치료반응은 93.3%였다. 결 론:약제 사용의 정당성 기준에 따른 정주 ciprofloxacin의 부적절한 사용은 연구에 포함된 대학병원에서 매우 흔하였다(73.1%). 그러므로 적절한 항생제 사용에 대한 교육과 제도적 장치가 매우 필요한 것으로 판단되었다.

휘발유/에탄올 혼합연료의 자연점화온도 예측

김신우,이의주 한국화재소방학회 2019 한국화재소방학회논문지 Vol.33 No.5

The recent development of biofuel production technology facilitates the widespread use of bioethanol and biodiesel bymixing them with fossil fuels. However, the use of these new blended fuels in combustion could result in severe safetyproblems, such as fire and explosion. In this study, numerical simulation was performed on the well-stirred reactor (WSR)to simulate the autoignition temperature (AIT) in homogeneous combustion and clarify the effect of ethanol addition on theAIT, the most important property for assessing the potential for fire and explosion. Response surface methodology (RSM)was introduced as a design of experiment (DOE), enabling the AIT to be predicted and optimized systematically withrespect to three independent variables: ethanol mole fraction, equivalence ratio, and pressure. The results show that theautoignition temperature primarily depends on the ethanol mole fraction and pressure, while the effects of the equivalenceratio are independent of the AIT. RSM accurately predicted the experimental AIT, indicating that this method can be usedto effectively predict the key properties involved in fires and explosions. 최근 다양한 생산기술의 발전을 통해 바이오연료의 생산이 크게 증가하였고, 석유와 같은 기존의 화석연료 등과혼합연료를 만들어 소비를 장려하고 있다. 이와 같은 새로운 연료의 등장은 기존 에너지 시스템으로의 적용에 있어화재 및 폭발의 위험성을 크게 증가시킬 수 있다. 따라서 본 연구에서는 대표적인 바이오연료의 소비형태인 휘발유/에탄올 혼합연료를 사용하는 연소장에서 화재 및 폭발의 위험성을 예측할 수 있는 기법을 제시하는 것을 목적으로하고 있다. 이를 위해 휘발유/에탄올 혼합기의 자연점화온도를 대상으로 수치해석하였고, 반응표면법을 이용하여 다양한 변수조건에 대해서 예측에 대한 유효성과 효율성을 판단해 보았다. 당량비, 압력, 에탄올 분율 등에 대한 자연발화온도 변화특성은 전체적으로 에탄올 함량과 압력에 큰 의존도를 보였으며, 에탄올 함량이 줄어들수록 압력에대한 영향이 줄어들었다. 또한 계산을 통한 실험값과 반응표면법을 통해 얻은 기대값이 매우 잘 일치함을 알 수 있었다. 따라서 연료의 혼합 등 다양한 조건에서 운전하는 연소장에서 자연점화온도를 매우 적은 데이터로서 정확하게예측할 수 있음을 확인하였다.

세균성 상부호흡기 감염

김신우 대한감염학회 2011 Infection and Chemotherapy Vol.43 No.5

Acute bacterial upper respiratory infections include acute rhinosinusitis, acute pharyngotonsillitis, acute laryngitis, and acute epiglottitis. These are common reasons for primary care visits. Acute bacterial sinusitis usually occurs as a secondary complication of acute viral sinusitis. Acute viral sinusitis will recover over the course of 7-10 days without antibiotics. Amoxicillin is a drug of choice for acute bacterial sinusitis in the practice guidelines. Patients with acute pharyngotonsillitis should be treated with antibiotics (amoxicillin) for 10 days with the purpose of prevention of rheumatic fever. Use of rapid antigen detection should be encouraged for the appropriate use of antibiotics, especially in Korea. Etiologies of acute laryngitis in adults are mainly viruses. However, M. pneumoniae, M. catarrhalis, H. influenzae are major bacterial pathogens of laryngtitis. Acute epiglottitis, cellulitis of the epiglottis, is a life-threatening infection. Airway keeping and antibacterial therapy against H. influenzae and other bacterial pathogens are main stays of management. Evidence-based approach is greatly in need for appropriate care for patients with bacterial upper respiratory infections.

A Fe-Si-B-Ni amorphous alloy manufactured by one roll melt-spinning method showed the crystallization temperature difference of a maximum $10^{\circ}C$ according to each lot. This temperature difference had a considerable influence on the annealing process to be conducted for obtaining the proper inductance of the alloy. The proper annealing temperature of the alloy was $480^{\circ}C$ and the annealing time increased as the crystallization temperature increased. The activation energy measured by Kissinger method increased as the crystallization temperature increased. Therefore, the annealing process must be adjusted by the crystallization temperature difference of the amorphous alloy.

Background : N,N-Dimethylformamide (DMF) has excellent solvent properties and is used intensively in the production of synthetic leather and resins. It has known to induce hepatotoxicity in human and animal. Biological monitoring of DMF has been evaluated by the excretion rate of urinary N-methylformamide (NMF). This study was conducted to examine the excretion of NMF from the workers exposed to DMF in a synthetic leather factory and to evaluate the prevalence of abnormal liver function associated with occupational exposure to DMF. Methods : The subjects were 35 workers exposed to DMF in a synthetic leather factory. Their urinary samples were collected and measured NMF concentrations. Also, DMF concentrations in air were measured by personal air sampler during their work. Liver function tests, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), r-glutamyltranspeptidase (GGT), and alkaline phosphatase (ALP), and hepatitis B surface antigen and antibody and anti-HCV assays were conducted. Results : The urinary NMF concentration was peak in 4 hours after workshift and it was not reduced to zero in the workers who engaged in coating department. The ratio of NMF (mg/L)/DMF was 3.7. The prevalence rate of abnormal liver function was 57.1%. And although the mean urinary excretion rate of NMF in the workers who were abnormal in liver function was higher than normal, it was not statistically significant to abnormal liver function in multiple logistic regression. Conclusion : It is necessary to seal the work processes and to examine the local exhaust systems periodically to reduce the level of DMF in work environment. Health educations for the workers and managers of the company should also be conducted, including the wear of personal protective equipment during works and routine regular medical examinations under special health check-up regulations.
