신승우,오태정,박세민,박종숙,장안수,박성우,우수택,안성환,박춘식 대한천식알레르기학회 2011 Allergy, Asthma & Immunology Research Vol.3 No.4

Purpose: We sought to identify asthma-related genes and to examine the potential of these genes to predict asthma, based on expression levels. Methods: The subjects were 42 asthmatics and 10 normal healthy controls. PBMC RNA was subjected to microarray analysis using a 35K array;t-tests were used to identify genes that were expressed differentially between the two groups. A multiple logistic regression analysis was applied to the differentially expressed genes, and area under the curve (AUC) values from receiver operating characteristic (ROC) curves were obtained.Results: In total, 170 genes were selected using the following criteria: P≤0.001 and ≥2-fold change. Among these genes, 57 were up-regulated and 113 were down-regulated in asthmatics versus normal controls. A multiple logistic regression analysis was done using more stringent criteria (P≤0.001 and ≥5-fold change), and eight genes were selected as candidate asthma biomarkers. Using these genes, 255 models (28-1) were generated. Among them, only 85 showed P≤0.05 by multiple logistic regression analysis. Based on the AUCs from ROC curves for the 85 models, we found that the best model consisted of the genes MEPE, MLSTD1, and TRIM37. The model showed 0.9928 of the AUC with 98% sensitivity and 80% specificity. Conclusions: MEPE, MLSTD1, and TRIM37 may be useful biomarkers for asthma.

본 연구는 국민은행의 주택금융수요 실태조사 자료를 이용하여 일반 서민가구의 주택담보 대출유형, 특히 주택금융공사의 보금자리론으로 대표되는 공공 모기지와 여타 민간은행의 민간 모기지간의 선택에 영향을 미치는 요인을 탐구하였다. 우리는 보금자리론이 출시된 2004년부터 2006년까지의 3개년치의 자료를 투입하여 다항 로짓(Multinomial Logit) 모델 및 중첩 로짓(Nested Logit) 모델을 적용하여 분석하였다. 미국의 실증분석 결과와는 달리 우리의 경우 서민가구들이 공공 모기지 보다는 민간 모기지를 선호하는 것으로 보인다. 그 이유로는 민간 모기지 상품의 다양성이나 이자유형 변경옵션과 같은 상품자체에 기인하는 속성과 함께 민간 대출기관의 느슨한 소득 검증(Income verification)과 같은 규제적 특성 역시 중요한 요인인 것으로 분석되었다.

뉴노멀 시대의 공공기관 원격보안 모델 개선방안

신승우,조인준 한국콘텐츠학회 2022 한국콘텐츠학회논문지 Vol.22 No.9

The pandemic caused by the COVID-19 virus, which has lasted for the past three years, has changed society and the way people live in many ways. These changes also affect cyberspace, so the pre-pandemic information security model and standards have limitations when applied to the current situation. In this paper, a new method to improve the information security model of public institutions was proposed in consideration of various situations in the new normal era. In other words, through the proposed information security model, the possibility of external intrusion is blocked in advance through the policy and technical supplementation of remote work, which is a weakness of the existing information security operation of public institutions. Also, how to prevent abnormal authentication attempts by building a secure VPN environment, how to prevent social engineering cyber attacks targeting fear and uncertainty caused by COVID-19, and how to use a smooth network and create a remote work environment. For this purpose, methods for securing service availability were additionally presented. 지난 3년간 지속된 COVID-19 바이러스에 의한 팬데믹 사태는 사회와 사람들의 삶의 방식을 다양한 방식으로 변화시켰다. 이러한 변화는 사이버공간에도 영향을 주어 팬데믹 이전의 정보보안 모델과 기준은 현재 상황에 적용할 때 한계가 있다. 본 논문에서는 뉴노멀 시대의 다양한 상황을 고려한 공공기관의 정보보안 모델 개선방안을 새롭게 제안하였다. 즉, 제시된 정보보안 모델을 통해 기존의 공공기관 정보보안 운영의 취약점인 원격근무의 정책적, 기술적 보완을 통해 외부 침입의 가능성을 사전 차단한다. 또한 안전한 VPN 환경 구축을 통해 비정상적 인증 시도를 방어하는 방법, COVID-19로 인한 두려움과 불확실성을 노린 사회공학기반 사이버 공격(Social Engineering Cyber Attack)을 예방하는 방법, 원활한 네트워크 사용 및 원격근무 환경 조성을 위해 서비스 가용성을 확보하는 방법 등을 추가로 제시하였다.

이 연구는 초등 예비교사의 체육교육신념과 수업지식 및 자기효능감의 관계를 규명하는데 목적이 있었다. 이를 위해 부산・인천・전북에 위치한 교육대학교의 재학생을 대상으로 편의표집방법을 이용하여 총 232명의 자료를 표집하 였다. 이중 신뢰할 수 없는 30부의 설문지를 제외한 총 202명의 자료가 실제 분석에 활용됐으며, 연구목적에 따라 통계 프로그램인 SPSS Statistics 21을 이용하여 빈도분석, 탐색적 요인분석, 신뢰도분석, 상관관계분석, 표준중다회귀분 석을 실시하였다. 연구결과를 살펴보면, 첫째, 초등 예비교사의 체육교육신념은 수업지식에 부분적으로 영향을 미치는 것으로 나타났다. 구체적으로 성숙주의는 수업내용지식에 정(+)적 영향을, 수업전략지식에는 부(-)적영향을 미치는 것으로 나타났다. 행동주의에서는 수업목표지식, 학생이해지식, 수업전략지식에 정(+)적 영향을, 수업내용지식에는 부(-)적 영향을 미치는 것으로 나타났다. 상호작용주의는 학생이해지식, 수업내용지식, 수업전략지식에 정(+)적 영향 을 미치는 것으로 나타났다. 둘째, 초등 예비교사의 체육교육신념은 자기효능감에 유의한 영향을 미치는 것으로 나타났 다. 성숙주의는 일반적 자기효능감에 부(-)적 영향을 미치는 것으로 나타났으며, 행동주의와 상호작용주의는 일반적, 사회적 자기효능감 모두 정(+)적 영향을 미치는 것으로 나타났다. 셋째, 초등 예비교사의 수업지식은 자기효능감에 유 의한 영향을 미치는 것으로 나타났다. 수업목표지식, 학생이해지식은 일반적, 사회적 효능감에 정(+)적 영향을, 수업내 용지식은 일반적 자기효능감에 부(-)적 영향을 미치는 것으로 나타났다. The purpose of this study is find out the relationship among physical educational belief, pedagogical content knowledge and self-efficacy of pre-service elementary school teachers. For this reason, we conducted a survey of undergraduate students in universities of education, located in Busan, Incheon and Jeollabuk-do, and 232 data were collected by the convenience sampling method. Except unreliable 30 questionnaires, 202 collected data were used by SPSS Statistics 21. This study was conducted by frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis and standard multiple regression analysis. Upon investigation our results lead to the following conclusions: At first, it showed that physical educational belief of pre-service elementary school teachers partially had influence on pedagogical content knowledge. In the concrete, maturism had a positive influence on pedagogical content knowledge, but negative influence on pedagogical strategy knowledge. Behaviorism had a positive influence on pedagogical objective knowledge, knowledge of students understanding and pedagogical strategy knowledge, but negative - on pedagogical content knowledge. Interactionism had a positive influence on knowledge of students understanding, pedagogical content knowledge and pedagogical strategy knowledge. Second, it was turned out that physical educational belief of pre-service elementary school teachers exerted an influence on self-efficacy. Maturism had a negative effect on general self-efficacy, but behaviorism and interactionism had a positive effect on general and social self-efficacy. Third, it was demonstrated that pedagogical content knowledge of pre-service elementary school teachers influenced the self-efficacy. Pedagogical objective knowledge, knowledge of students understanding had a positive influence on general and social self-efficacy, but pedagogical content knowledge had a negative influence on general self-efficacy.

S-PRG filler를 함유한 치면열구전색제의 미세누출 및 항우식효과

신승우,김종수,Shin, Seungwoo,Kim, Jongsoo 대한소아치과학회 2013 大韓小兒齒科學會誌 Vol.40 No.4

치면열구전색은 생물막의 축적을 물리적으로 막아주며 박테리아에 의해 형성되는 산물질에 화학적 장벽 역할을 한다. 1999년 S-PRG(Surface reaction-type pre-reacted glass ionomer) 필러기술이 개발되었는데 S-PRG 필러는 수분 존재 하에서 스스로 분해되지 않으면서, 지속적으로 불소유리가 가능하다. 이에 저자는S-PRG 필러를 포함하는 치면열구전색제의 미세누출 및 인접 법랑질에 대한 항우식 효과를 기존의 유동성레진 치면열구전색제와 비교해 보고자 한다. 건전한 소구치, 대구치를 실험대상으로 사용하였다. S-PRG 필러를 함유해 불소를 유리하는 치면열구전색제 Beautisealant$^{(R)}$(Shofu, Japan)를 실험군으로, 유동성레진 치면열구전색제 Concise$^{(R)}$(3M ESPE, USA)를 대조군으로 선정하였다. 미세누출실험을 위해 실란트 변연 1 mm를 제외한 나머지 치아에 손톱광택제를 2회 도포 후 2% 메틸렌블루 용액에 24시간 동안 보관 후 수세하였다. 항우식효과의 평가는 인공우식용액에 9일간 보관 후 수세 후 시행하였다. 수세한 시편들은 투명레진에 매립 후 현미경 관찰을 위해 절단하였다. 통계분석은 미세노출의 정도는 Chisquare test를, 측정된 우식의 깊이는 Mann-Whitney test를 이용해 두 군 간의 유의성을 검증하였다. S-PRG 치면열구전색제와 유동성레진 치면열구전색제의 미세누출 차이는 관찰되지 않았지만, S-PRG 치면열구전색제는 유동성레진 치면열구전색제 보다 더 높은 항우식효과를 보이는 것으로 나타났다. Pit and fissure sealant prevents biofilm accumulation, plays a role in forming a barrier to acidic substance made by the bacteria. The Surface reaction-type pre-reacted glass ionomerI(S-PRG) filler was developed in 1999. S-PRG filler releases fluoride continuously and does not decompose under wet conditions. The aim of this study was to test the microleakage and anticariogenic effect to adjacent enamel of S-PRG filler-containing pit and fissure sealant. Sound premolars and molars were used in this study. A S-PRG filler-containing pit and fissure sealant, Beautisealant$^{(R)}$(Shofu, Japan) was used for this experiment, the composite resin sealant Concise$^{(R)}$(3M ESPE, USA) was used as control. For the microleakage test, all teeth surface were double coated with finger nail varnish, with the exception of a 1.0 mm window around the restoration margins. The teeth were immersed in 2% methylene blue solution for 24 hours and then rinsed in tap water. For the anticariogenic effect evaluation, all tooth were immersed in artificial carious solution for 9 days and rinsed with tap water. Each tooth was embedded in orthodontic acrylic rein and subsequently sectioned longitudinally in a bucco-lingual direction with a low-speed diamond saw. The cut sections were examined using a stereomicroscope. Differences in microleakage between the two groups were not different significantly. But the S-PRG filler-containing pit and fissure sealant showed higher anticariogenic effect than that of flowable resin sealant.

申勝雨,金鎭國,金炳洙 최신의학사 1967 最新醫學 Vol.10 No.8

80 patients diagnosed as having acute abdomen have been studied from the roentgenological and clinical points of view. 75 of the patients were operated upon and 14 were not. X-rays taken in the simple erect position were divided into four groups according to the patterns of bowel gases and fluid levels shown. Cases with typical spring-coiled appearances were classified as group 1, cases with sun-ray patterns as group 2 and cases with' appearances of fluid levels without plica circularis or haustral mar-kings as group 3. Cases showing irregular gas patterns in the bowel were classified as group 4. Operative findings were of two types, the simple type in which disease was localized in the intestine, and the complex type in which both the intestine and the adjoining tissues were involved. The following results were obtained : 1. The sex incidence was about 2:1, males predominating, (59 male : 30 female). The greatest number of patients were between 21 and 40 years of age, 17 being between 31 and 40 }rears and 14 being 21 and 30 years. 2. 44 patients (57/) of those receiving operative treatment reached the hospital within 24 hours of the onset of symptoms: 11 patients (75%) of those who were not operated on arrived at the hospital later than 24 hours after the first symptoms had begun. 3. The majority of patients operated upon, were found to have perforation of the bowel(64%) 19 of these (40%), being due to typhoid fever. The next most common finding at operation was intestinal obstruction in 22 patients (29%): intussusception was the cause of obstruction in 8 (36%), of these cases. 4. X-rays taken in the simple, erect position of the 48 cases of perforation of bowel, showed free gas in 31 (64.2%). Among these cases two were roentgenologically normal, 5 cases were placed in group 1, 12 cases in group 2 and 12 ir, group 3. 5. X-rays taken in the simple erect position on 19 patients found to have intestinal obstruction, showed one case to have normal bowel patterns, while 8 cases were placed in group 1, 6 case sin group 2 and 7 cases in group 3. 6. The relationship betv,,een the x-ray appearances of the bowel, and the intra-abdominal findings at operation was as follov,,s: 9 cases (75%) of simple type were placed in group 1, and 21 cases (33%) of complex type were placed in group 2; 28 complex cases (44%) were placed in group 3. Of the patients who did not have surgry, 6 cases (43%) were placed in group 1 and other 6 cases (43%) were placed in group 4.

Sevelamer 인결합제와 투석환자의 Chronic Kidney Disease-Mineral Bone Disorder 관리

신승우,신혜연 한국임상약학회 2016 한국임상약학회지 Vol.26 No.2

Background: Sevelamer is associated with reduced complications of chronic kidney disease-mineral bone disorder (CKD-MBD) resulted from hyperphosphatemia, which may contribute mortality, in CKD patients with dialysis. So far clinical outcomes of sevelamer on mortality and risk of cardiovascular mortality related to CKD-MBD are debating. Purpose of this study was to evaluate the effectiveness of sevelamer HCl on mortality of secondary hyperparathyroidism (SHPT), risk of cardiovascular mortality and, frequency of osteopathy in end stage renal disease (ESRD) patients with dialysis. Methods: We retrospectively reviewed the electronic medical records of 536 patients with ESRD, who were admitted for moderate to severe SHPT, for 36 months. 75 patients who met inclusion criteria were evaluated for the efficacy of sevelamer (mean serum iPTH = 487.5 pg/mL). Results: Sevelamer intervention was not associated with increased three-year survival time compared with non-sevelamers group [average survival month: 30.4 months in sevelamer group, 26.8 months in non-sevelamer group, p = 0.463]. Sevelamer intervention was not associated with significant mortality benefit and cardiovascular mortality benefit as compared to non-sevelamer group [sevelamer group: non-sevelamer group, all-cause mortality (iPTH > 600 pg/mL): 14.3% (1/34): 20% (1/41) p = 0.962, OR = 0.935, 95% CI, 0.058-14.98, heart disease mortality: 6.67% (2/30): 0% (0/32) p = 0.138]. Sevelamer was not associated with significantly lower cumulative incidence of osteopathy compared to non-sevelamer group (sevelamer group: non-sevelamer group, 5.9% (2/34):9.8% (4/41); p = 0.538; OR = 0.578; 95% CI, 0.099-3.367). Conclusion: Sevelamer was not associated with decreased all-cause mortality and risk of cardiovascular mortality compared to non-sevelamer group in ESRD patients with SHPT.
