목 적 : 요로 감염증 환아를 요로계 기형이 있는 요로 감염군과 이러한 기형이 없는 요로 감염군으로 나누어 반복 요 배양검사에서 균의 재배양 양성율을 비교하여 반복 요 배양 검사의 임상적 유용성에 대해 알아보고자 하였다. 방 법 : 1998년 1월 1일부터 2008년 8월 1일까지 경상대학교병원에 내원하여 발열 또는 요로감염의 전형적인 임상양상을 보이고 농뇨가 있으면서 소변배양 검사에서 균이 $10^5$ colony-forming units (CFU)/mL개 이상 자란 요로 감염 환아 369명을 대상으로 2일 후에 다시 요 배양검사를 시행하였다. 요로기형이 없는 요로 감염군과 요로기형(방광요관역류, 수신증)을 동반하는 요로 감염군으로 나누어 각각의 군의 성비, 나이, 재배양 양성율을 통계적으로 분석하였다. 통계량 분석은 Students t-test와 Fishers exact test를 사용하였고 SPSS 14.0 버전을 사용하여 P값이 0.05미만인 경우에 통계적으로 유의한 것으로 평가하였다. 결 과 : 요로 기형이 없는 요로 감염군의 성비는 M:F=1.9:1 (183/96)이었고 요로 기형을 동반하는 요로 감염군의 성비는 M:F=3.5:1 (70/20)으로 요로 기형이 있는 요로 감염군에서 통계적으로 유의하게 남자가 많았다(P=0.019). 나이는 요로 기형이 없는 요로 감염군이 $0.82{\pm}1.83$세이고 요로 기형이 있는 요로 감염군이 $1.18{\pm}2.57$세로 통계적으로 차이가 없었다. 재배양 양성율은 정상요로를 가진 요로 감염군이 3/279 (1.1%)이고 요로 기형이 있는 요로 감염군이 1/90 (1.1%)으로 통계적으로 차이가 없었다. 결 론 : 정상 요로를 가진 요로 감염군과 요로 기형이 있는 요로 감염군에서의 균의 재배양 양성율은 통계적으로 차이가 없을 뿐만 아니라 재배양 양성율 자체의 빈도도 매우 드물었다. 따라서 반복 요 배양 검사 결과를 치료의 성공 지표로 삼는 것은 임상적 유용성이 부족하며, 정상 요로를 가진 요로 감염군과 요로 기형이 있는 요로 감염군 모두에서 반복 요 배양 검사는 불필요한 검사라고 생각된다. Purpose : We aimed to compare the frequency of positive repeat urine cultures 48 hours after antimicrobial treatment between anatomically normal and abnormal urinary tract Infection (UTI) groups to determine the potential clinical usefulness of the tests. Methods : We reviewed medical records of 930 patients under age 14, who had been admitted for UTI at Gyeongsang National University Hospital from January 1, 1998 to August 1, 2008. The eligible patients were divided into two groups the anatomically normal UTI group and the anatomically abnormal UTI group. Statistical analyses were performed with variables consisting of the sex ratio, age distribution and the frequency of positive repeat urine cultures of each group. Results : The sex ratio of the anatomically normal UTI group was M:F=1.9:1, whereas that of the anatomically abnormal UTI group was M:F=3.5:1 (P=0.019). For age distribution, it was found that the mean age of the anatomically normal UTI group was $0.82{\pm}1.83$ years, whereas that of the anatomically abnormal UTI group was $1.18{\pm}2.57$ years (P=0.113). The frequency of positive repeat urine cultures in the anatomically normal UTI group was 3/279 (1.1%), whereas that of the anatomically abnormal UTI group was 1/90 (1.1%) (P=0.675). Conclusion : We conclude that performing a repeat urine culture is not justified in terms of clinical usefulness, and it is unreasonable to use the results as an index of therapeutic success. A follow-up urine culture is unnecessary in patients with both the anatomically normal and abnormal UTI group.

The purpose of this paper is to examine the change of the times on the transmission rate of broadcast message. In order to find out the research results, I collected past recorded news tapes and selected 22 radio news out from era of Japanese Imperialism, 1950's, 1960's and contemporary age. Next I measured each announcer's reading rate, and compared change on news-reading rate between present and past approximately 50 years ago. The results of study with such procedures and methods are as follows : the average reporting rate of newscasters in each era is different. From these results, we can easily grasp diachronic change in the transmission rate of broadcast message. Namely, the results show us that present announcers read news faster than the group of past era of Japanese Imperialism by 68%.

Purpose: This study was designed to identify the factors affecting healing of Stage 2 pressure ulcer in an acute care facility in Korea. Methods: 286 Stage 2 pressure ulcers of 145 patients were examined. Data were collected in the period between October $1^{st}$, 2006 and September $30^{th}$, 2007. Data were analyzed with Kaplan-Meier survival analysis for cumulative recovery rate of Stage 2 pressure ulcers. Cox proportional hazard model was used to examine effects of multiple variables simultaneously. Results: Out of 286 initial Stage 2 pressure ulcers, 204 (71.3%) pressure ulcers healed completely. The median time to heal was 15 days according to Kaplan-Meier survival analysis. Cox proportional hazard model showed that the Stage 2 pressure ulcers healed more quickly when pressure redistribution surfaces were used (p<.001, HR=2.184), patients were administered with vitamins (p= .038, HR=1.451), and the size of the pressure ulcers were small (${\leq}3.0cm^2$, p= .006, HR=1.765). Conclusion: The factors contributing to the healing of Stage 2 pressure ulcer in an acute care setting were the application of pressure redistribution surface, small ulcer size (${\leq}3.0cm^2$), and the administration of vitamins.

박경희,류현욱,서용진,이우선,홍광준,박진성,Park, Kyung-Hee,Ryu, Hyun-Wook,Seo, Yong-Jin,Lee, Woo-Sun,Hong, Kwang-Jun,Park, Jin-Seong 한국재료학회 2003 한국재료학회지 Vol.13 No.7

Tin dioxide ($SnO _2$) thin films were deposited at $375^{\circ}C$ on alumina substrate by metal-organic chemical vapor deposition. A few hillocks like a cauliflower were observed and the number of hillock on thin film surface increased with annealing temperature in air atmosphere. The oxygen content and the binding energy during air annealing at$ 500^{\circ}C$ came to close the stoichiometric $SnO_2$. The cauliflower hillocks seem to be the result of the continuous migration of the tiny grains to release the stress of an expanded grain. Sensitivity of CO gas depended on annealing temperature and increased with increasing annealing temperature.

Tin dioxide($_SnO2$) thin films were deposited on alumina substrate by metal-organic chemical vapor deposition (MOCVD) as a function of temperature and time. Thin films were fabricated from di-n-butyltin diacetate as a precursor and oxygen as an oxidation. The microstructure of deposited films was characterized by X-ray diffraction and field emission scanning electron microscopy(FE-SEM). The thickness was linearly increased with deposition time and $SnO_2$structure was found from $375^{\circ}C$ for the deposition time of 32 min. The maximum sensitivity to 500ppm CO gas was observed for the specimens deposited at $375^{\circ}C$ for 2 min at the operating temperature of $350^{\circ}C$. Gas sensitivity to CO increased with decreasing the film thickness. The sensing properties of response time, recovery and sensitivity of CO were changed with variations of substrate temperature and time.

The purpose of this study is to analyze the characteristics of core competencies of university students and to investigate the relationship with creative personality. To do so, core competency inventory(Park Sung-mi, 2011) and creative personality inventory(Hah Ju-hyen, 2001) were conducted for undergraduate students according to the gender, grades, and majors. Participants were 1009 students from 10 universities across the country. In addition, multiple regression analysis was performed using 8 sub-factors of creative personality as independent variables and 3 core competencies as dependent variables. The results are as follows. First, the core competencies are classified into job communication, job performance, and job attitude. Men were higher than women in job performance. In case of major, all three competencies of the students of education department were high. However, there were no significant differences by grade. Second, there was a significant positive correlation ( r =.718) between core competencies and creative personality. Among the creative personality traits of university students, self - confidence has the strongest influence on openness, perseverance for job performance, and job attitude. However, adventure and imagination were not related to core competencies. 본 연구의 목적은 대학생의 핵심역량의 특성을 분석하고 창의적 인성과의 관계를 알아보는데 있다. 설문조사 기간은 2016년 6월 7일 부터 2016년 9월 12일까지 진행 되었으며, 전국의 10개 대학의 1009명의 피험자들을 대상으로 대학생 핵심역량 검사 (박성미, 2011)와 창의적 인성 검사(하주현, 2001)를 실시하였다. 대학생 핵심역량 특성을 알아보기 위해서 성별, 학년별, 전공계열별 차이를 분석하였다. 그리고 창의적 인성의 8개 하위 특성을 독립변인으로 3가지 핵심역량을 종속변인으로 하여 다중회귀분석을 수행하였다. 그 결과는 다음과 같다. 첫째, 대학생의 핵심역량은 직무소통, 직무수행, 직무태도 역량으로 구분하였고 직무수행 역량에서 남자가 여자보다 높았으며, 전공계열별에 차이에서는 세 역량 모두 사범대학이 높게 나타났다. 다만, 학년별로는 유의한 차이가 나타나지 않았다. 둘째, 대학생 핵심역량과 창의적 인성은 유의한 정적 상관관계(r=.718)가 있었다. 창의적 인성 하위 특성 중에서 대학생의 직무 소통에는 개방성, 직무수행에는 인내집착, 직무태도에는 자기확신이 가장 강력한 영향을 미치는 변인으로 나타났다. 그러나 모험심과 상상은 핵심역량에서 제외되었다.

A new carbon electrode was made based on activated carbon (AC) using TiO2 binder compared with a Pt sputtered electrode as the counter electrode for dye-sensitized solar cells(DSSC). Cyclic voltammetry and impedance spectroscopy were used to investigate electrochemical properties of both AC electrode and Pt electrode. The photocurrent-voltage characteristics were influenced by both, the roughness factor and electrical resistance of the carbon counter electrode. The voltage increased by about 50 mV using the carbon counter electrode compared to the Pt counter electrode because of positive shift of the formal potential for iodide/triiodide redox couple. Also, electrochemical properties of AC electrode was superior to those for Pt electrode on the basis of the measurement of CV and impedance data. The AC counter electrode has the merit of improving the fill factor and conversion efficiency of the DSSC by reducing its internal resistance.

통일신라토기 골호에 나타난 심미의식

박경희 ( Park Kyung-hee ) 한국디자인트렌드학회 2010 한국디자인포럼 Vol.28 No.-

통일신라시대의 왕들이 화장을 유언하였던 사회적인 분위기 속에서 불교의 영향으로 화장문화가 발달했음은 출토된 골호의 형태와 문양에서 확인할 수 있다. 통일신라시대에 등장하는 탑형·보주형·원형 등 다양한 골호의 형태와 연화문·영락문·연주문·원권문 등의 문양에서 전통의 미를 존중하면서 새로운 것을 응용하는 조화의 심미의식, 국가를 초월하여 외국의 문물을 적극적으로 수용하여 원만하게 하는 원융의 심미의식을 발견할 수 있다. 그리고 예전의 토기가 대부분 무덤에 넣는 부장품이었음에 비해 극락왕생을 염원하는 사람들의 소망을 골호의 형태와 문양에 그대로 담아 표현하던 신심의 심미의식을 지니고 있었음을 알 수 있다. The cremation culture was advanced with Buddhism effect. We can find it through testaments of the kings in unified Shilla period and we can be able to confirm from forms and patterns of excavated earthen cinerary urns. The aesthetic consciousness of the harmony and the amalgamation are discovered which through various cinerary urns of pagoda style·magic pear stylel·round shape style etc. and lotus flower patterns·patterns of various and the round shape etc. in unified Shilla period. The former is to respect tradition and apply the new thing and the latter is to surpass actively the civilization of the foreign nation and to unite into one.
