Early diagnosis and treatment of osteomyelitis provide good prognosis and prevent severe complications. Therefore, it is important to early diagnose and treat before the bony changes are observed in conventional radiograms. Authors experienced three cases of early osteomyelitis, and scintigrams were useful to differentiate them from other diseases. The purpose of this report was to aid in the early diagnosis and treatment of osteomyelitis occurred in the jaws. The characteristic features were as follows: 1. In clinical examination, the patients complained mild pain and localized swelling in the jaws. 2. In radiographic findings, the conventional radiograms showed relatively mild bony changes in the jaws. 3. The more severe periosteal reactions were observed in radiograms in children than in adult patient. 4. It showed marked increased uptake of radioisotopes in all scintigrams. 5. The three phase bone scannings were helpful to differentiate osteomyelitis from soft tissue diseases.

A computer program is developed in order to figure out the physical insight of the combined dust removal equipment, that is, cyclonic electrostatic precipitator. The computer program employs Patankar's control-volume based finite-difference method, in which SIMPLEC algorithm is used for the resolution of pressure-linked momentum equation. Further two equation k-ε model is incorperated for Reynolds stresses and many empirical formulae are employed for dust charging and electric resistivity. A series of extensive parametric investigations are performed in terms of tangential velocity(swirl intensity), applied voltage across two electrodes, and particulate diameters, etc. It is found that the electrostatic force gives much more strong effect, expecially for small particulate, on the dust removal than the centrifugal force. Other calculated results are physically acceptable and consistent.

The utilization of multi-media to deliver education content has been rapidly increasing recently in early childhood education institutions. However, in many cases multi-media is used as classroom tools without thorough review of their educational function and possible problems. According to Grundy(1991), the use of any medium in a curriculum should not be accepted without critical review. In addition, the medium should also be assessed as an area of overall curriculum development. Accordingly, this research studies the utilization of multi-media from a postmodern perspective of the early childhood curriculum. It emphasizes the following points: First, multi-media should deliver content that pursues diversity and multiplicity considering the socio-cultural context of the learners. Second, multi-media should be used for not only individual activities but also collaborative work to promote interaction. Third, multi-media should be capable of encouraging the active participation of the learners. In conclusion, this research suggests that the use of multi-media in early childhood education institutions is significant not only as an additional teaching tool but also as the means to enable new approaches to early childhood education curriculum.

The purpose of this study was to elucidate whether the molecular defect of acid-base transporters in renal tubules is related to the functional defect of urinary acidification in distal renal tubular acidosis(RTA). We performed NH₄Cl, furosemide, or bicarbonate loading test to evaluate renal acidification function, and immunohistochemistry using antibodies to H^+ -ATPase, Cl^-/HCO₃^- exchanger(band-3 protein), and Na^+/K^+ -ATPase in kidney tissue in 6 patients with RTA and renal cell carcinoma patients as normal controls. Kidney tissue was obtained either by percutaneous needle biopsy(RTA) or nephrectomy(NC). The results were as follows; 1) In all six RTA patients, proton secretory defect of distal acidification was shown by a failure to lower the urine pH after NHC1 loading or furosemide test or abnormally low urine-blood pCO₂ difference during bicarbonate loading. In two patients with RTA, proximal acidification defect was combined, which was demonstrated by increased fractional excretion of bicarbonate. 2) In mal control, intense H^+ -ATPase and band-3 protein staining was observed in collecting ducts. 3) In distal RTA patients, H6+ -ATPase and band-3 protein staining was not demonstrable or markedly decreased in the intercalated cells of distal nephron. 4) In two patients who had both proximal and distal RTA, H^+ -ATPase staining was markedly decreased in the brush border of proximal tubules as well as the distal nephron. In conclusion, the defect of acid-base transporters in renal tubule was related with the functional defect of urinary acidification in distal RTA.

목적: 임상적으로 FENa가 일과성 신손상 (T-AKI)과 지속성 신손상 (P-AKI)을 감별하는 데 많이 사용되지만 이뇨제를 사용한 환자에서 FENa는 유효 혈류량 결핍 상태에서도 증가하게 되어 진단적 정확성이 떨어진다고 알려져 있다. 본 연구에서는 이뇨제 투여상황에서 FE(Na)와 비교하여 FE(Urea)의 진단적 유용성에 대하여 알아보고자 하였다. 방법: 107명의 급성 신손상 환자를 임상적 특성에 따라 일과성과 지속성 신손상 군으로 나누고 이를 다시 이뇨제 투여 유무에 따라 재분류하였다. ROC 곡선에 따라 계산된 cutoff value에 따라서 일과성 신손상을 정의하였고 이뇨제 투여로 인한 cutoff value의 변화에 따른 민감도와 특이도를 비교하였다. 결과: AKI가 발생한 107명의 모든 환자중 검사 이전에 경험적으로 이뇨제를 사용한 경우가 67명으로 63%를 보였고, 일과성 신손상군의 경우는 52명 중 27명으로 52%를, 지속성 신손상군의 경우는 55명 중 45명으로 73%를 보였다. ROC curve에 따라 cutoff value를 FE(Na)≤1.5 FE(Urea)≤30으로 하였을 때 T-AKI를 진단하는 데 사용된 두 값의 민감도와 특이도는 모든 환자군에서 FE(Na)가 81%, 98%를, FE(Urea) 가 94%, 82%를 보였다. 이뇨제 비투여군에서는 FE(Na)가 96 %, 100%를, FEUrea가 92%, 87%를 보였으며, 이뇨제 투여군에서는 FE(Na)가 63%, 98%를, FE(Urea)가 96%, 83%를 보였다. 결론: 이뇨제를 사용한 경우 P-AKI를 진단하는데 FE(Urea)도 FE(Na) 정도의 진단적 유용성을 가진다. Purpose: Although fractional excretion of sodium (FE(Na)) has been used to distinguish transient-acute kidney injury (T-AKI) from persistent-AKI (P-AKI), the availability of FE(Na) in the diagnosis of T-AKI is reported low in patients with diuretics use. We compared the diagnostic performance of fractional excretion of urea (FE(Urea)) with that of FE(Na) in patients with diuretics use. Methods: One hundred seven AKI patients were classified as having T-AKIor P-AKI according to the clinical context. Each group was again subdivided according to exposure to diuretics. According to the cut off value generated by receiver operating characteristic (ROC) curves, sensitivity and specificity of FE(Na) and FE(Urea) were compared with each other. Results: The numbers of patients administered with diuretics were 67 out of total 107 AKI patients (63%), 27 out of 52 (52%) of T-AKI patients, and 40 out of total (65) 55 (73%) of P-AKI patients. When the cutoff value of T-AKI was defined as FE(Na) ≤1.5 and FE(Urea) ≤30 according to the ROC curves, sensitivity and specificity of FE(Na) were 96% and 100% in non-diuretics group, and 63% and 98% in diuretics group, respectively. Sensitivity and specificity of FE(Urea) were 92% and 87% in non-diuretics group, and 96% and 83% in diuretics group, respectively. Conclusion: FE(Urea) is as good as FE(Na) at distinguishing T-AKI from P-AKI in patients administered with diuretics.

As technology scales into sun-90㎚ domain, manufacturing variation become an increasingly significant portion of circuit delay. Therefore, delays must be modeled as statistical distribution during both analysis and optimization. This thesis applies incremental, parametric statistical static timing analysis(SSTA) to perform gate sizing with a required yield. The proposed algorithm sized gates which has higher criticality yielded by utilizing probability of critical path and considering path correlation. The result verified an effectiveness of the delay optimization by gate sizing.

대학생의 입학만족도, 전공만족도, 자아존중감, 진로확신이 대학생활만족도에 미치는 영향

나은숙(Eun Suk Na),신서영(Seo Young Shin) 안전문화포럼 2022 안전문화연구 Vol.- No.19

대학생활만족도는 대학생들로 하여금 학업에 대한 노력과 성공적인 학교생활을 영위 할 수 있는데 큰 역할을 한다. 대학이라는 새로운 환경에서 학업적, 사회적, 정서적 측면에서 자신의 목표를 위해 나아가는 과정임을 고려할 때 학생들의 대학생활 만족을 위해 지원하는 제도적 장치가 더욱 정교하게 설계되어야 한다. 이에 본 연구는 대학생의 입학만족도, 전공만족도, 자아존중감, 진로확신 정도를 파악하고, 이들 요인이 대학생활만족도에 미치는 영향을 파악하고자 하였다. 2021년 5월 4일부터 6월 14일까지 서울 소재 S대학교 재학생 4129명을 대상으로 ㈜글로벌리서치 조사 수행기관을 통해 구조화된 설문지를 사용하여 설문조사를 실시하였다. 수집된 자료는 SPSS/WIN 20.0을 이용하여 분석하였으며, 통계분석방법은 빈도, 일원배치분산, 상관관계, 다중회귀분석으로 실시하였다. 분석결과 첫째, 대학생들의 입학만족도와 전공만족도, 진로확신, 자아존중감, 대학생활만족도가 평균 이상으로 높게 나타났다. 둘째, 입학만족도는 학년이 어릴수록 만족도가 높으며 전공만족도와 진로확신은 여자가 남자에 비해 점수가 더 높았다. 자아존중감은 성별, 월평균생활비에 따라 유의한 차이가 있었는데 여학생보다 남학생이 더 높았으며 월평균 50만원 이상의 생활비를 사용한다고 응답한 학생들이 자아존중감이나 진로확신, 대학생활만족도가 더 높게 나타났다. 셋째, 대학생활만족도 수준을 불만족, 보통, 만족 세 집단으로 나누어 각 집단별 입학만족도, 전공만족도, 자아존중감, 진로확신에 어떠한 차이가 있는지를 알아본 결과 대학생활 만족 수준이 높은 집단이 낮은 집단에 비해 입학만족도나 전공만족도, 자아존중감, 진로확신 점수가 높았다. 넷째, 대학생들의 입학만족도, 전공만족도. 자아존중감, 진로확신, 대학생활만족도 간의 상관관계가 있는 것으로 나타났다. 다섯째, 대학생활만족도에 영향을 주는 요인을 분석한 결과, 대학생활만족도에 가장 설명력을 보인 요인은 입학만족도였으며 다음으로 전공만족도, 진로확신 순으로 나타났다. 따라서 대학생의 대학생활만족도를 높이기 위해서는 전공수업의 질을 높이고 학과에서 적절한 학업지도, 교과과정의 개선 및 특성화된 개별 프로그램을 실시해야 한다. 입학만족도는 외적 요인으로 학생들이 입학하기 전에 대학의 인지도나 평판에 영향을 받는 것이기 때문에 이미지를 높이기 위한 방안이 필요하다. 또한 진로확신, 자아존중감을 가질 수 있도록 상담과 장학금 지원을 강화가 필요하다. Campus life satisfaction plays a big role in enabling university students to make an effort to study and to lead a successful school life. Considering that the university is a process that advances toward one's own goals in academic, social, and emotional aspects in the new environment of university, the institutional device that supports students' campus life satisfaction needs to be designed more precisely. This study tried to understand the degree of college students' admission satisfaction, major satisfaction, self-esteem, and career confidence, and the effect of these factors on campus life satisfaction. From May 4 to June 14, 2021, a survey was conducted using a structured questionnaire through Global Research Co., Ltd.'s research agency for 4,129 students of S University in Seoul. I performed analysis of frequence, pearson correlation analysis, one-way ANOVA, multiple regression analysis by 「SPSS Statistics 20」program and got follow results. At first, University students' admission satisfaction, major satisfaction, career confidence, self-esteem, and Campus life satisfaction were higher than average. Secondly, in terms of admission satisfaction, the younger the grade, the higher the satisfaction, and the satisfaction of the major and the certainty of the career were higher in women than in men. Thirdly, The group with the high level of campus life satisfaction had higher scores for admission satisfaction, major satisfaction, self-esteem, and career confidence than the group with low compus life satisfaction. Fourthly, It was found that there was a correlation among university students' admission satisfaction, major satisfaction, self-esteem, career confidence, and campus life satisfaction. Fifthly, as a result of analyzing factors affecting Campus life satisfaction, the factor that showed the most explanatory power for Campus life satisfaction was admission satisfaction, followed by major satisfaction and career confidence. Therefore, in order to increase campus life satisfaction of university students, it is necessary to return to the basics and improve the quality of major classes, and to provide appropriate academic guidance, curriculum improvement, and specialized individual programs in the department. Since admission satisfaction is an external factor that is affected by the recognition or reputation of the university before students enter, measures to enhance the image are needed. In addition, it is necessary to strengthen counseling and scholarship support so that they can have career confidence and self-esteem.
