Purpose : Recently, different results about factors affecting accurate quantitation of 24-hr urinary protein(24UP) amount using spot urine protein/creatinine ratio(PCR) have been reported. The current study was designed to evaluate correlation between 24UP amounts and PCR in children, and the effect of 24UP amounts, age, sex, and glomerular filtration rate(GFR) on this correlation. Methods : Among 94 patients who visited the department of pediatrics in Busan Paik Hospital from March 2002 to August 2002, 68 patients whose urinary creatinine excretion was ${\geq}15mg/kg/day$ were included in this study. All the patients were divided into I, II/A, B group(I : 24UP<500 mg/day, II : $24UP{\geq}500mg/day$, A : <10 years of age, B : ${\geq}10years$ of age). Pearson correlation analysis was performed between 24UP and PCR to evaluate the relationship. We defined fractional difference between 24UP and PCR, and then performed multiple regression analysis with 24UP amount, age, GFR and fractional difference. Results : There was a strong positive linear correlation between 24UP and PCR(R=0.936, P<0.0001) in all patients, and the correlation was also good in each group. Using PCR cutoff values of 0.5, the PCR provided high sensitivity, specificity, positive and negative predictive value in predicting 24UP amount ${\geq}500mg$. The factors affecting accurate quantitation of proteinuria using spot urine PCR was age, not 24UP amount, GFR or sex. Conclusion : Spot urine PCR is a useful test but has limitations in predicting 24UP amount. Therefore, it should be used only as screening method. Age-adjusted PCR cutoff values may be necessary to predict 24UP amount in children with proteinuria.

본 연구에서는 국내에서 보급되고있는 전용 PC 통신 소프트웨어 사용자 인터페이스의 사 용편이성을 향상시키기 위한 설계요인을 분석하고자 한다. 사용편이성을 평가하는 척도로서 정차적 복잡도를 이용하였다. 절차적 복잡도를 기술하기 위해 KLM을 이용하였으며, 국내4 대 전용 PC통신 소프트웨어 각각에 대해 분석하였다. 분석결과 국내에 보급되고 있는 전용 PC 통신 소프트웨어는 사용편이성 측면에서 차이가 발견되었다. 이 차이는 PC 통신 소프트웨어 사용자 인터페이스의 설계요인 및 PC통신 서비스를 위한 데이터베이스 설계요인의 차이에서 비롯 되는 것으로 판단된다.

pm이 편리한 교통수단으로 이용이 금증함에 따라 교통사고 또한 급증하였다. pm은 안전장치 부재로 유사교통수단인 자전거 보다 1.5배 이상의 사고 심각도를 보인다. 이에 pm 사고 심각도 요인을 분석하였다.분석 결과 사고 심각도를 감소 시키기 위해서는 pm과 차량의 교통이 분리되고, pm 안전 이용을 위한 교육이 필요한 것으로 판단된다.

Change detection algorithms take two image frames and return the locations of newly introduced objects which cause differences between the images. This paper presents a new change detection method, which classifies intensity changes due to introduced objects, reflected light and shadow from the objects to their neighborhood, and the noise, and exactly localizes the introduced objects. For classification and localization, first we analyze the histogram of the intensity difference between two images, and estimate multiple threshold values. Second we estimate candidate object boundaries using the gradient difference between two images. Using those threshold values and candidate object boundaries, we segment the frame difference image into multiple regions. Finally we classify whether each region belongs to the introduced objects or not using textures in the region. Experiments show that the proposed method exactly localizes the objects in various scenes with different lighting.

This study set out to analyze the effects of user personality on the brand satisfaction and loyalty of SNS to identify factors influencing SNS usage. For that purpose, the study defined extraversion, curiosity, and self-esteem, three factors of Instagram user personality, as exogenous variables, focusing on Instagram, which has made a relatively sharp rise in the usage rate among many different SNS applications. With brand satisfaction and loyalty set as endogenous variables, the investigator introduced brand satisfaction as a mediating variable for the effects of extraversion, curiosity, and self-esteem on brand loyalty. A survey was conducted with Korean people with an experience of using Instagram, and total 396 questionnaires were used in final analysis. The findings show that all of three exogenous variables had positive (+) effects on brand satisfaction with extraversion and curiosity having positive (+) effects on brand loyalty, as well. And the findings demonstrate that brand satisfaction was a mediating variable and that curiosity was the personality factor that had the biggest influences on satisfaction and loyalty.

This study concerns whether the public spirit of medical services, which is the foundational goal of national hospitals, is being realized. To derive results regarding this question, it is necessary to identify the determinants that influence the choice of national hospitals. The data are based on the number of cases of medical service use among the data for 6 years from 2008 to 2013 in the Korea Medical Panel, and the subjects were limited to those who were 18 years old or older. In the final analysis, 14,365 cases of hospitalization service uses were employed. For the research method, Andersen's behavioral model theory was applied, and predisposing, enabling, and individual factors were determined to be variables. Logistic regression analysis was conducted to analyze the determinants of national hospital choice factors. It was found that the rate of use of national hospitals was very low, with 5.23% for hospitalization services. Furthermore, socioeconomically vulnerable people, such as the elderly, low-income people, the national meritorious and medical care beneficiaries, chronic patients, and disabled patients are more likely to choose national hospitals than private hospitals. Therefore, for the appropriate management of medical service use for low-income vulnerable groups, it is necessary to discuss the enhancement of primary medical care in national healthcare.

Artists using exhibition spaces can select exhibition spaces considering marketing activities provided by operators or organizations of exhibition spaces, so it is necessary to study the relationship between marketing activities and satisfaction factors. This study examines marketing mix 7P factors, satisfaction, and prior studies as a theoretical background to demonstrate the decisive factors of the artist's exhibition hall satisfaction. As a result of analyzing the questionnaire collected from 144 artists used the exhibition hall, among the 7P factors of marketing mix, product, price, and progress process influenced the satisfaction of the exhibition hall, and the influence was in order of progress, product, and price. The suggestions are as follows. First, among the 7P factors in marketing mix, the fact that products, prices, and progress influencing the satisfaction of the exhibition place emphasizes factors related to the actual exhibition. Second, among the 7P factors in the marketing mix, the process had the greatest influence on the satisfaction of the exhibition hall, which means that the service delivery process is important.

The objectives of this study identify the factors that affect the quality of MTS services, to determine the effects of these service quality factors on customer's satisfaction and customer's loyalty. The results are as follows: First, The Four factors, i.e., tangibles, reliability, responsiveness, and assurance, represent statistically marginal significance in explaining the relationship between MTS service quality factors and customer's satisfaction. Second, The Five factors, i.e., rapidness, tangibles, responsiveness, empathy, and assurance represent statistically marginal significance in explaining the relationship between MTS service quality factors and customer's loyalty. Third, There are some differences in assurance/period of utilization, empathy/period of utilization in using MTS services according to social statistics. This article provides the paradigm of new convergence on IT and finance.
