This article analyzes the academic achievement of students who entered A university from 2011 to 2012 using grade point average (GPA). The purpose of this analysis is to find the relationship between admission factors and academic achievement. Contrary to our expectation, GPA of student selected from KSAT is higher than that of selected from CSAT. So, designing and running university entrance type, it is necessary to consider admission factors deliberately.

The purpose of this study is to investigate the university academic achievements on the high school graduates of specialized vocational high school and general high school selected by the university admissions officer system. The implications of this study will contribute to improve development of university admission through the analysis of university admission achievements and correlation between university admission factors and university academic achievements. Participants of this study were university students selected by admission officer system in 2011 and have enrolled in the university for 6 semesters at A university. The results of this study are as follows: First, when it comes to the grades of university admission factors, graduates from specialized vocational high school outperformed those from general high school. Second, when it comes to the correlation between university academic achievements and university admission factors, graduates from specialized vocational high school slightly outperformed those from general high school. Third, when it comes to the correlation between university academic achievements and university academic achievements, graduates from specialized vocational high school showed poorer performance than those from general high school in overall courses and liberal arts courses. However, in major courses, graduates from specialized vocational high school outperformed those from general high school. Finally, when it comes to the development of university academic achievements, both of them showed a tendency of being improved as they advanced through school. Based on the findings of this study, several implications can be made as follows: First, it is necessary to improve the application ratio and application method of university admission factors. Second, it is required to provide preparatory courses of university to help graduates from specialized high school get adapted to university course of study.

To study the relationship between the levels of chemical pollutants and the number of daily total hospital admissions for respiratory diseases and to find the effect of temperature/relative humidity on the admission number, Wong et al. [17] introduced the varying-coefficient single-index model (VCSIM). As pointed out, it is a popular multivariate nonparametric fitting technique. However, the tests of the model have not been very well developed. In this paper, based on the estimators obtained by the local linear technique, the average method and the one-step back-fitting technique in the VCSIM, the generalized likelihood ratio (GLR) tests for varying-coefficient parts on the VCSIM are established. Under the null hypotheses the new proposed GLR tests follow the $\chi^2$-distribution asymptotically with scale constant and degree of freedom independent of the nuisance parameters, known as Wilks phenomenon. Simulations are conducted to evaluate the test procedure empirically. A real example is used to illustrate the performance of the testing approach.

The purpose of this study is to analyze the performance difference between public and private hospitals. It is believed that private hospitals may have a better performance compared to public hospitals. The study support the hypothesis. By analyzing 425 acute-care hospitals in Korea, this research shows a less performance of public hospitals compared to private hospitals. Higher labor and administrative cost by public hospitals may account for the difference, and it means they are not effective at cost control. Managers in public hospitals, therefore, should pay attention on cost-reducing issues to regain managerial efficiency of organizations.

The Emergency Department (ED) is an integral part of hospitals. Admissions from the ED account for a significant proportion for a hospital's activity. Ensuring a timely and efficient flow of patients through the ED is crucial for optimising patient care. In recent years, ED overcrowding and its impact on patient flow has become a major issue facing the health sector. Simulation is rapidly becoming a tool of choice when examining hospital systems due to its capacity to involve numerous factors and interactions that impact the system. An analytical simulation model is used to investigate potential impacts by changing the following aspects of ED (physical layouts; number of beds; number and rate of patient arrivals; acuity of illness or injury of patients; access to radiology and pathology services; hospital staffing arrangements; and access to inpatient beds). Results of a significant numerical investigation at a hospital are also presented.

Generalized linear models have various applications for data arising from many kinds of statistical studies. Although the response variable is generally assumed to be generated from a wide class of probability distributions we focus on count data that are most often analyzed using binomial models for proportions or poisson models for rates. The methods and results presented here also apply to many other categorical data models in general due to the relationship between multinomial and poisson sampling. The novelty of the approach suggested here is that all conditional distribution s can be specified directly so that staraightforward Gibbs sampling is possible. The prior distribution consists of two stages. We rely on a normal nonconjugate prior at the first stage and a vague prior for hyperparameters at the second stage. The methods are demonstrated with an illustrative example using data collected by Rosenkranz and raftery(1994) concerning the number of hospital admissions due to back pain in Washington state.

Objectives: The lack of advance planning in a public health emergency can lead to wasted resources and inadvertent loss of lives. This study is aimed at forecasting the needs for healthcare resources following the expansion of the coronavirus disease 2019 (COVID-19) outbreak in the Republic of Kazakhstan, focusing on hospital beds, equipment, and the professional workforce in light of the developing epidemiological situation and the data on resources currently available. Methods: We constructed a forecast model of the epidemiological scenario via the classic susceptible-exposed-infected-removed (SEIR) approach. The World Health Organization's COVID-19 Essential Supplies Forecasting Tool was used to evaluate the healthcare resources needed for the next 12 weeks. Results: Over the forecast period, there will be 104 713.7 hospital admissions due to severe disease and 34 904.5 hospital admissions due to critical disease. This will require 47 247.7 beds for severe disease and 1929.9 beds for critical disease at the peak of the COVID-19 outbreak. There will also be high needs for all categories of healthcare workers and for both diagnostic and treatment equipment. Thus, Republic of Kazakhstan faces the need for a rapid increase in available healthcare resources and/or for finding ways to redistribute resources effectively. Conclusions: Republic of Kazakhstan will be able to reduce the rates of infections and deaths among its population by developing and following a consistent strategy targeting COVID-19 in a number of inter-related directions.

The purposes of this study are to identify how university's entrance examination system is related to private education, and to explore how to improve the university of education entrance system in order to reduce private education costs. For these purposes, 116 teachers of senior students in high school in Daegu and Gyeongbuk and 107 pre-service teachers who had experienced the entrance of the university were surveyed in order to find out the perception of the relationship between admissions elements and private education. As a result, it is possible to concentrate more on school education by strengthening high school grades in the entrance examination. However, there was other opinion that the strengthening high school grades in the university entrance could lead to the further increase in the cost of private education. As there are big differences in the perception of the screening factors between rural areas (Gyeongsangbuk-do) and large cities (Daegu), it is necessary to introduce the entrance examination system considering the characteristics of each region. Third-year teachers in high schools argued that university admissions should reduce the rate of the College Scholastic Ability Test (CSAT) and increase the rate of interviews. The results of this study suggest that the improvement of the university entrance examination system to reduce the cost of private tutoring requires securing fairness of document evaluation, strengthening interviews, and opening interview questions.

Background: An appropriate use of hospital beds can improve productivity of hospital significantly. The authors' previous study revealed that approximately one third of Korean hospital bed days and one sixth of admissions were inappropriately used, when it was measured by Appropriateness Evaluation Protocol(AEP) and Delay Tool modified into Korean situation by the authors. This study aims to evaluate applicability of the instruments in a new hospital. More specifically the study aims to measure appropriateness of the instruments used by newly trained nurse reviewers at a new hospital setting. Methods: In order to evaluate applicability of these instruments, agreement rates of the scores recorded by newly trained nurse reviewers with by skilled nurse reviewer and also compared with the scores recorded by physician's implicit decision were assessed. Agreement rates were derived from concurrent application of AEP and Delay Tool to 52 admissions and 104 patient days from internal medicine, pediatrics, and general surgery of one university hospital. Overall agreement rate, specific nonacute agreement rate, and kappa statistics were used to indicate level of agreement. Results: Overall agreement rates on appropriateness between newly trained nurse reviewers and skilled nurse reviewer were 100% in admission and 98% in bed days. Overall agreement rates on reason for inappropriateness between newly trained nurse reviewers and skilled nurse reviewer were 96% in admission and 91% in bed days. Overall agreement rates between newly trained nurse reviewers and physician reviewer were 86% in admission and 87% in bed days. Conclusion: Results indicated that AEP and Delay Tool were applicable to a new hospital in detecting inappropriate utilization of beds and reasoning of the inappropriateness. These instruments could contribute to enhance efficiency of hospital use, through continuous monitoring of level of inappropriate hospital use at national or individual hospital level.
