Current mathematics of CSAT(College Scholastic Ability Test) faces time to prepare examination questions according to the new curriculum making this year the last. MEST(Minister of Education, Science and Technology) already decided the range of examination in 2008. However, the discuss about how to construct the questions and what form of questions should be set was not conducted enough. Mathematics items of CSAT will have to undergo changes both in 2012 and 2014. Also, reconstruction of the examination questions for the past 16 years and the exploration of the new direction are strongly required. To accord with these requirements, this study analyze Japan's college entrance exam, NCTUA(National Center Test for University Admissions) which is the most similar to our exams. And then on the basis of this, the applicable implication to set mathematics questions in 2012 and 2014 CSAT will be deducted.

The purpose of this study is to provide the basic data for establishing a unique admissions promotion strategy for each university and to innovate the paradigm of university admissions promotion through the examples of central universities in the practice of PR promotion based on big data analysis. To this end, prior literature related to university publicity (marketing), and recognition of prospective college students who visited the university, and database data were defined and analyzed as big data. As a result, first, the preliminary studies related to college entrance exam promotion (marketing) increased dramatically in the 2000s and 2010s as part of preparing for countermeasures against population decline in school age. Responding to the need for an admissions promotion strategy to accelerate visits to prospective college students, the database data analysis result suggested the selection and concentration of entrance exam strategies based on the university's regional and academic characteristics.

Due to a decrease in the number of college prep students which was triggered by the low birth rate since 1990, it is predicted, beginning 2016, that the entrance quota for colleges will exceed the number of applicants for college admissions. This serious imbalance between supply and demand raises serious problems for the regional universities, many of which have already been struggling to recruit new students and even considered closing down the schools. In an effort to securing best high school students, many of the schools have been developing various unique and specialized selectional processes for the applicants. In this research, through a statistical analysis of special admission processes for vocational high school students who were admitted to a regional state-run university (University A), I tried to find a way to effectively deal with the student management. Statistically analyzing these first-year students' enrollment and their adjustment processes as well as the departmental relationships and gender differences, I tried to find some better ways to secure good applicants. It is expected that this study will not only be utilized as guide to adopt a way to bypass the enrollment quota in order to secure talented students but also be served as a reference that will help the students adapt themselves to school life until they graduate. It is also expected that this study will be expanded in such a way as to compare it with other models and even develop a new type of college entrance system that would fit future college admission policies.

Objectives: This study was conducted to assess the applicability of the Appropriateness Evaluation Protocol (AEP) for public hospitals in Korea. Methods: In May 2016, 1500 admission claims were collected from Korean public district hospitals using stratified random sampling. Of these claims, 560 admissions to 37 hospitals were retrieved for analysis. Medical records administrators determined the appropriateness of admission using the criteria detailed in the AEP, and a physician separately assessed the appropriateness of admission based on her clinical judgment. To examine the applicability of the AEP, the concordance of the decisions made between a pair of AEP reviewers and between an AEP reviewer and a physician reviewer was compared. Results: The results showed an almost perfect inter-rater agreement between the AEP reviewers and a moderate agreement between the AEP reviewers and the physician. The sensitivity and specificity of the AEP were calculated as 0.86 and 0.56, respectively. Conclusions: Our findings suggest that the AEP could potentially be applied to Korean public hospitals as a reliable and valid instrument for assessing the appropriateness of admissions.

Background: Inhaled corticosteroids (ICSs) are the most essential medication for asthma control. Many reports suggest that the usage of ICSs improves not only the control of asthma symptoms but also prevents exacerbation. We investigated whether increases in ICS prescriptions are associated with decreases in asthma exacerbation in the clinical practice setting. Methods: We retrospectively analyzed the database of adult asthma patients who had visited a tertiary referral hospital, the Asan Medical Center between January 2000 and December 2009. The number of emergency department (ED) visits, admissions, intensive care unit (ICU) care, deaths, and ICS prescriptions were analyzed to evaluate the time trend of asthma exacerbation as a function of the ICS prescription rate during the ten years. Results: The numbers of ED visits, admissions, and episodes of ICU care decreased during the ten years (p<0.001, p=0.033, p=0.001, respectively) while the number of ICS prescriptions increased (p<0.001). We found a correlation between the number of ICS prescriptions and the number of ED visits, admissions, or ICU care. For these outcomes, the correlation coefficients were r=-0.952, p<0.001; r=-0.673, p=0.033; r=-0.948, p<0.001, respectively. Conclusion: The number of ICS prescriptions increased during the past ten years while the number of asthma exacerbations decreased. Our results also showed a negative correlation between the ICS prescription rate and asthma exacerbation in the clinical practice setting. In other words, an increase in ICS prescription may be a major cause of a decrease in asthma exacerbations.

It has already been 17 years since the first implementation of the Korean College Scholastic Ability Test (CSAT). Having been administered so many CSAT tests including practice tests, criticisms have been made against CAST tests being stuck to the same pattern and focusing mainly on knowledge-based items. To address this issue, we analyzed the chemistry items of the Japanese National Center Test for University Admissions (NCTUA) administered in January of 2009 with regard to content factors, behavioral domains, item types, and noted any peculiarities in comparison to CSAT. Also, we estimated the predicted percentage of correct answers from the perspectives of Korean candidates to arrive at implications for chemistry items of CSAT.

Objective : To investigate the effects of trauma center establishment on the clinical characteristics and outcomes of trauma patients with traumatic brain injury (TBI). Methods : We enrolled 322 patients with severe trauma and TBI from January 2015 to December 2016. Clinical factors, indexes, and outcomes were compared before and after trauma center establishment (September 2015). The outcome was the Glasgow outcome scale classification at 3 months post-trauma. Results : Of the 322 patients, 120 (37.3%) and 202 (62.7%) were admitted before and after trauma center establishment, respectively. The two groups were significantly different in age (p=0.038), the trauma location within the city (p=0.010), the proportion of intensive care unit (ICU) admissions (p=0.001), and the emergency room stay time (p<0.001). Mortality occurred in 37 patients (11.5%). Although the preventable death rate decreased from before to after center establishment (23.1% vs. 12.5%), the difference was not significant. None of the clinical factors, indexes, or outcomes were different from before to after center establishment for patients with severe TBI (Glasgow coma scale score ${\leq}8$). However, the proportion of inter-hospital transfers increased and the time to emergency room arrival was longer in both the entire cohort and patients with severe TBI after versus before trauma center establishment. Conclusion : We confirmed that for patients with severe trauma and TBI, establishing a trauma center increased the proportion of ICU admissions and decreased the emergency room stay time and preventable death rate. However, management strategies for handling the high proportion of inter-hospital transfers and long times to emergency room arrival will be necessary.

Background: Hospital admissions for ambulatory care sensitive conditions (ACSCs), which are widely used as an indicator of poor access to primary care, can be used as an efficiency indicator of healthcare use in countries providing good access to health care. Korea, which has a national health insurance (NHI) system and a good supply of health care resources, is one such country. To quantify admission rates of ACSC and identify characteristics influencing variation in Korean health care institutions. Methods: By using NHI claims data, we computed the mean ACSC admission rate for all institutions with ACSC admissions. Results: The average ACSC admission rate for 4,461 institutions was 1.45%. Hospitals and clinics with inpatient beds showed larger variations in the ACSC admission rate (0%-87.9% and 0%-99.6%, respectively) and a higher coefficient of variation (7.96 and 2.29) than general/tertiary care hospitals (0%-19.1%, 0.85). The regression analysis results indicate that the ACSC admission rate was significantly higher for hospitals than for clinics (${\beta}=0.986$, p<0.05), and for private corporate institutions than public institutions (${\beta}=0.271$, p<0.05). Conclusion: Substantial variations in ACSC admission rates could suggest the potential problem of inefficient use of healthcare resources. Since hospitals and private corporate institutions tend to increase ACSC admission rates, future health policy should focus on these types of institutions.

The purpose of this study was to survey appropriateness of admission and days of care for the cerebral ischemia patients as a basis to provide an effectiveness of hospitalization. The authors retrospectively reviewed the medical records of cerebral ischemia patients in two hospitals from November 1997 to February 1998. Of 194 medical records reviewed, there were 2108 medical days. I t is used a 'Appropriateness Evaluation Protocol' previously developed by Gertman and Restuccia (1981) and translated by Department of Health Management, Seoul National University and Korea Institute for Health Services Management (1993), It was found that the 'Appropriateness Evaluation Protocol' had a high inter-rater reliability(k=.92), Statistical significant was tested by using the percentage, mean, and logistic regression by SAS 6.12. The results were as follows; 1. The appropriate admissions were 87.6%, days of care 63.4%, and the average length of stay $10.9{\pm}6.7$ days. 2. The reasons of inappropriate admissions were for work-up(75.0%) and conservative care (25.0%). Major reasons of inappropriate days of care were 'cases in which the medical purpose of hospitalization has been accomplish or can be addressed in a less setting(45.0%)', and 'cases in which there is a delay in performing the work-up or treatment which required patients is hospitalized (44.4%)'. 3. Appropriate days of care were higher as ageing. Appropriate days of care were higher in patients with lower accademic back ground than those of upper college graduates, and in the patients who enter a hospital via emergency room than out-patients department. Appropriate days of care were higher in the patient with MCA infarction, and lower in the patient with cerebellar infarction than the patient with lacunar infarction. Appropriate days of care were higher in attack first than attack above second, in nomortension patients than hypertensive, and lower in groups who engaged in semi-private room and public room than private room in hospital. Appropriate days of care were higher in shorter length of stay than longer length of stay. 4. Diagnosis, admission path, and appropriate days of care explained appropriate admissions. Diagnosis, appropriate admissions, hypertension explained appropriate days of care. According to the above results, author confirms the substantial amount of inappropriate hospital bed utilization. To reduce inappropriateness, it is necessary to develop some alternative services such as home care services or nursing home with which can be replaced inpatient services and to introduce policy such as case management which includes Critical Pathway for consistent management. And, it should be followed the further study for the effectiveness.
