In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant

Background Subacromial pain syndrome (SAPS) is one of the causes of shoulder pain in workers performing repetitive upper extremity movements. However, there have been no studies on physical characteristics such as shoulder total rotational range of motion (ROM) and external to internal rotation muscle strength ratio of workers. Purpose The purpose of this study was to compare the total rotational ROM and external to internal rotation muscle strength ratio in workers with and without SAPS. Study design A cross-sectional study Methods This study included 35 workers with SAPS and 32 workers without SAPS. The total rotational ROM were measured using Smart KEMA motion sensor, and external to internal rotation muscle strength were measured using Smart KEMA pulling sensor. Results The results showed that there were significant differences in the total rotation ROM between the groups (p<0.05). However, no significant difference was found in the external to internal rotation muscle strength ratio (p>0.05). Conclusions Assembly line workers with SAPS had limited total rotational ROM. However, the ratio of external to internal rotation muscle strength ratio was not different for workers without SAPS. These characteristics can be considered factors that should be considered in evaluating workers with SAPS and establishing a treatment plan.

코로나 바이러스(COVID-19) 팬데믹으로, 전국의 대학들이 온라인 플랫폼을 사용한 비대면 강의를 시행하고 있다. 따라서 응급환자간호 임상실습 교육에 맞는 온라인 프로그램을 개발하고, 간호학생에게 적용하여 그 효과를 확인해보고자 시도 되였다. 본 연구는 양적자료와 질적자료를 분석한 방법론적 연구로, G광역시 N대학교 성인간호학교수 3인이 G광역시 종합병원 간호부장과 응급실 수간호사들에게 자문을 구하여 학생들의 교과목과 관련된 요구도 조사 후에, 4학년을 대상으로 응급환자간호 임상실습 온라인 프로그램을 ADDIE모형에 따라 개발하였다. 프로그램은 총 4주 동안 진행되었으며, 1주에 영상 4시간, 과제 2가지로 구성하였고, 실시간 쌍방향 화상집담회도 포함되었다. 총 96명 학생 자료가 수집되었으며, SPSS/WIN 22 프로그램으로 분석하였다. 자료 분석결과 교과목 만족도 부분에서‘학습목표 연계성’이 총 6.0만점에 평균 5.58±0.98로 가장 점수가 높았다. 응급간호 학습성취도에서는 ’BLS 수행‘이 평균 5.47±0.74로 가장 점수가 높았으며,‘낙상예방 간호수행’(5.39±0.77),‘응급환자 기록수행’(5.30±0.70), ‘감염예방 간호수행’(5.27±0.736) 순이었다.‘3학년 때 시행한 대면임상실습경험과 이번학기 비대면임상 실습수업 경험을 비교하여 내가 생각하는 이번학기 수업의 장점은 무엇인가?’에 관한 질적자료를 Keyword로 추출하여 Wordcloud로 제시한 결과 답변을 한 77명의 학생들 중‘간호과정경험’이라고 답한 경우가 13명(16.9%)로 가장 많은 빈도를 나타내었고,‘자세한 교수설명’이 10명(13.0%),‘사례기반실습’이 9명(11.7%)‘시간과 공간의 제약이 없다(Anytime anywhere)’고 답한 경우가 8명(10.4%) 순으로 나타났다. 이에, 개발된 온라인 프로그램을 활용한 응급환자간호 임상실습이 학생들의 교과목 요 구도를 반영한 학생들의 학습성취도를 파악하였으며, 대면실습과 비교하여 교과목 만족도가 높게 나타나 개발된 온라인 프로그램을 향후 응급환자간호 임상실습에서 활용 가능할 것으로 생각된다. Purpose: Clinical practicums via non-face-to-face methods were inevitable due to the COVID-19 pandemic. We developed an online program for emergency nursing care and identified the feasibility of the program and the learning achievements of students. Methods: This was a methodological study. The program was developed by three professors who taught theory and clinical practicum for adult nursing care and clinical experts. Students received four hours of video content and two task activities every week in four-week program. Real-time interactive video conferences were included. Qualitative and qualitative data were collected. Results: A total of 96 students participated in the program. The mean score for overall satisfaction with the online program was 4.72(±1.02) out of 6. Subjects that generally had high learning achievement scores were basic life support care, fall prevention, nursing documentation, infection control, and anaphylaxis care. As a result of a content analysis of 77 reflective logs on the advantages of this program, students reported that “experience in applying nursing process,” “case-based learning and teaching method,” and “No time and space constraints” were the program’s best features. Conclusion: Collaboration between hospitals and universities for nursing is more important than ever to develop online content for effective clinical practicum.

김원경(Weon-Gyeong Kim),노은경(Eun-Kyung Noh) 한국의료정보교육협회 2018 보건의료생명과학논문지 Vol.6 No.2

본 연구에서는 최근 다양해지고 있는 의료시장과 병원들 간의 차별화 전략이 요구되어지고 있는 상황에 의료 소비자인 고객들이 병원 브랜드 이미지에 따라 고객의 이용의사에 미치는 영향을 분석해 보았다. 구조화된 설문지를 이용하여 광역시에 소재한 3개의 병원 주변 아파트 주민을 대상으로 인구학적 특성과 대상자의 건강수준 및 의료이용의 특성, 각 병원에 따른 브랜드 이미지 등의 차이를 알아보았다. 본 연구결과를 통해 고객 이용의사와 관련하여 M병원의 경우 검사 시 병원의 호감도, 기억, 기호도에 유의한 차이를 보였고, 입원 시 에는 호감도, 기억, 진료도, 기호도 모두 유의한 차이가 있었으며, 수술시 에는 기억, 진료도가 이용의사에 유의한 영향을 미쳤다. K병원의 경우에는 입원치료 시에만 호감도, 기억, 진료도, 기호도 모두 유의한 차이가 나타났고, D병원의 경우에는 입원 시에는 호감도와 기억, 수술 시에는 진료도에 유의한 차이를 보이는 것으로 나타났다. 본 연구결과 브랜드이미지가 병원 이용의사에 미치는 부분은 입원을 하였을 때 가장 유의한 차이를 보였다. 병원에 입원하여 장기적인 치료를 받아야할 경우 브랜드 이미지가 병원 이용의사에 더욱더 중요한 수단으로 작용 하는 것을 알 수 있었다. 브랜드는 기업뿐만 아니라 병원도 브랜드에 대한 인식이 높아져야 할 것이라고 생각한다. With the medical markets recently diversifying and hospitals needing differentiating strategies, this study analyzed the effect of hospital brand image on the choice of doctors by medical consumers. Targeting the residents near three hospitals in a metropolitan city, a survey was conducted on hospital brand image, etc. according to the demographic characteristics, health levels, and characteristics of medical-service use. The findings of this study are as follows. Regarding the choice of doctors by the medical consumers, in the case of hospital M, there was a significant difference in good feeling about the hospital, memory, and preference, and in relation to hospitalization, there was a significant difference in good feeling about the hospital, memory, diagnosis and treatment, and preference. In relation to surgery, memory and diagnosis and treatment had a significant effect on the choice of doctors by the medical consumers. In the case of hospital K, only in relation to hospitalization, there was a significant difference in good feeling about the hospital, memory, diagnosis and treatment, and preference. In the case of hospital D, in relation to hospitalization, there was a significant difference in good feeling about the hospital and memory, and in relation to surgery, there was a significant difference in diagnosis and treatment. The findings of this study revealed that the effect of brand image on doctors was greatest in relation to hospitalization. This suggests that in relation to long-time treatment under hospitalization, hospital brand image is an important factor influencing the choice of doctors by medical consumers. As such, hospitals need measures to boost their brand awareness.

김경환(Gyeong Hwan Kim),손성실(Seong Sil Son),박찬혁(Chan Hyeok Park),김준혁(Joon Hyeok Kim),김도훈(Do Hoon Kim),강동원(Dong Weon Kang) 대한CT영상기술학회 2013 대한CT영상기술학회지 Vol.15 No.1

목적 뛰어난 심혈관계 묘사로 진단적 가치가 높지만 여러 제한적 사항들로 인해 어려움을 겪던 소아 Chest CTA 검사에 있어 체중에 따른 적절한 전체 조영제 volume과 flow rate에 따른 enhancement time 및 scan delay time을 연구하고 이를 보편적 방법으로 제시하고자 한다. 대상 및 방법 CT 장비는 MDCT 128 channel dual source; Somatom Definition Flash (Siemens medical system: Germany)를 사용하였고 체중에 따른 적절한 전체 조영제 volume과 flow rate에 따른 enhancement time 및 scan delay time을 계산하는 식을 이용하여 본원에서 2012년 1월 1일부터 6월 30일까지 Chest CTA를 시행한 환아 107명을 대상으로 30건의 표본을 얻어 HU값을 측정하여 평균값을 구하였다. 107건에 관하여 각 영상에 4단계 점수를 부여하여 정성적 평가를 시행하였다. 결과 30건의 검사에서 측정된 HU의 평균값은 각 각 RA는 416.08, RV는 404.25, LA는 335.58, LV는 333.25, Aorta arch는 353.41로 측정되어 조영이 잘된 것으로 평가하였다. 3명의 평가자가 각 영상에 부여한 평가의 평균점수는 3.00이었으며 각 영상의 평가점수별 백분율은 1점이 0.93%, 2점이 18.07%, 3점이 60.44%, 4점이 20.56%를 차지하였다. 2점 이상이면 진단적 가치가 있다고 평가하였기에 비교적 뛰어난 진단적 가치가 있다고 판단하였다. 결론 소아 3D Chest CTA검사는 여러 제한적 고려사항을 감수하더라도 선천성 심혈관 질환과 수술 후 심혈관 장애 진단에 도움이 될 것으로 생각된다. 또한 본 연구에서 제시한 체중에 따른 flow rate와 start scan delay time 계산 방법은 보편적인 방법으로 다른 장비에서 응용이 가능할 것으로 생각되며 재검사를 줄여 소아에게 있어 피폭선량감소와 조영제에 대한 위험부담을 줄일 수 있을 것으로 사료된다. Ⅰ. Purpose It is suggested of scan delay time and enhancement time for children according to flow rate and contrast medium volume which are related to weight. While CT has high diagnostic value for cardiovascular description, it has several difficulties of pediatric chest CTA. Ⅱ. Meterial and Methods CT equipment is MDCT 128 channel dual source; Somatom Definition Flash (Siemens medical system: Germany). it is studied with sample of 30 in 107 children from January 1st 2012 to June 30th 2012. HU values were measured and it was calculated in average in using the formula which calculates scan delay time and enhancement time according to weight. 4 steps score was given each image and then quantitative and qualitative evaluation was performed. Ⅲ. Result Average value of HU for 30 cases were RA, RV, LA, LV, and Aorta of 416.08, 404.25, 335.58, 333.25 and 353.41 respectively which was evaluated as good enhancement. 3 valuators gave scores to each image from 0 to 4. It’s average score was 3.00. It’s percentages were 0.93%, 18.07%, 60.44%, and 20.56% of 1, 2, 3 and 4 score respectively. if it is more then 2 point it has diagnostic value. therefore these images have relatively outstanding diagnostic value. Ⅳ. Conclusions Even though we put up with consideration of several limitation, pediatric 3D chest CTA help to diagnose pediatric cardiac after operation and with disabilities. In addition it is possible to apply the formula with other CT equipment in universal method. It is expected that burden for contrast medium would be reduced to children due to reexamination reduction.

Wild boar is closely related to domestic pigs in terms of genetic homogeneity and the possibility of a source of infection by contact. This study investigated the prevalence of viral diseases from wild boars inhabiting Gyeongsangnam-do, South Korea. A total of 374 blood samples were collected and sub-jected to antigen tests to detect African swine fever virus (ASFV), Porcine circovirus type-2 (PCV2), Porcine reproductive and respiratory syndrome virus (PRRSV). For seroprevalence, PCV2, PRRS, classical swine fever virus (CSFV), Aujezsky’s disease (ADV), and foot and mouth disease virus (FMDV) were investigated. The antigenic analysis revealed 73 positive cases (19.5%) for PCV2, while no positive cases for ASFV and PRRSV. For the antibody test, 225 (60.2%), 2 (0.5%), and 48 (12.8%) cases were detected against PCV2, PRRSV, and CSFV, respectively. There were no antibodies detected against both ADV and FMDV. Our results suggest that the viruses infecting both wild boar and do-mestic pig, mainly PCV2, are circulating in the wild boar population thus, the consistent monitoring of prevalence in wild boar will be needed for transboundary spillover to the domestic pig.

( Jun Young Kim ),( Gyeong-hun Park ),( Min Ji Kim ),( Hyun Bo Sim ),( Weon Ju Lee ),( Seok-jong Lee ),( Shin-woo Kim ),( Young Hoon Jeon ),( Yong Hyun Jang ),( Do Won Kim ) 대한피부과학회 2018 Annals of Dermatology Vol.30 No.2

Background: Increasing evidence suggests a pivotal role for neuronal inflammation in response to replicating varicella zoster virus in the development of postherpetic neuralgia (PHN). Objective: In this study, we investigated the value of serum levels of various inflammatory markers in acute herpes zoster (HZ) as predictors for the development of PHN. Methods: A total of 116 patients with acute HZ were enrolled in this study. We measured scores on the pain visual analogue scale (VAS) at baseline and at 1, 3, and 6 months after diagnosis of HZ. We defined PHN as pain greater than 1 on the VAS lasting for more than 6 months. Serum samples for laboratory assay, including complete blood count were obtained at the initial visit. Correlations between the levels of each inflammatory marker and the development of PHN were evaluated. Results: Levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), lymphocyte count, and albumin showed significant correlations with development of PHN in univariate analysis. Levels of ESR, CRP, and lymphocyte count also showed significant correlations in multivariate analysis. ESR level showed stronger correlations with development of PHN than levels of CRP and lymphocyte count. Conclusion: In this study, we confirmed that elevated ESR was an independent and significant predictor of PHN in patients with acute HZ. To validate these results, further well-designed, randomized clinical trials are needed. (Ann Dermatol 30(2) 158∼163, 2018)

Yong-Seok Choi(Yong-Seok Choi),Min Gyeong Kim(Min Gyeong Kim),Jong-Ho Lee(Jong-Ho Lee),Joo-Yong Park(Joo-Yong Park),Sung-Weon Choi(Sung-Weon Choi) 대한구강악안면외과학회 2022 대한구강악안면외과학회지 Vol.48 No.5

Objectives: This study aimed to analyze the clinicopathological prognostic factors affecting the survival of patients with oral squamous cell carci-noma (OSCC). Materials and Methods: A retrospective study was conducted on patients with OSCC who received treatment at the Oral Oncology Clinic of the Na-tional Cancer Center (NCC) from June 2001 to December 2020. The patients’ sex, age, primary site, T stage, node metastasis, TNM staging, perineural invasion (PNI), lymphovascular invasion (LVI), differentiation, surgical resection margin, smoking, and drinking habits were investigated to analyze risk factors. For the univariate analysis, a Kaplan-Meier survival analysis and log-rank test were used. Additionally, for the multivariable analysis, a Cox proportional hazard model analysis was used. For both analyses, statistical significance was considered when P<0.05. Results: During the investigation period, 407 patients were received surgical treatment at the NCC. Their overall survival rate (OS) for five years was 70.7%, and the disease-free survival rate (DFS) was 60.6%. The multivariable analysis revealed that node metastasis, PNI, and differentiation were significantly associated with poor OS. For DFS, PNI and differentiation were associated with poor survival rates. Conclusion: In patients with OSCC, cervical node metastasis, PNI, and differentiation should be considered important prognostic factors for postop-erative survival.
