  • We empirically verified whether there are different educational investment behaviors according to university admissions, using the Korean Education and Employment Panel data. The results are as follows; the average annual private education cost and the average amount of time spent studying alone per week of rolling admission type were lower than those of regular admission type. Also, rolling admission applicants had longer leisure and sleeping hours, such as watching TV and using computers. These results show the possibility that the university admission system will change the educational investment behavior. Furthermore, there is a possibility to induce the human capital investment to be made efficiently.

  • Objectives : To gather information about the factors which influence the interest and intention of admission into charging nursing hones for the elderly(CNH), as these homes represent an important method for resolving the problems related to the rapid population aging occurring in Korea. Methods : A face-to-face interview survey was carried out with 320(men 159, women 165) patients over 60 years old who were admitted at 2 university hospitals and 5 general hospitals in the Busan area between December 1998 and March 1999. Data were analyzed through t-test, ANOVA, correlation and multiple regression analysis. Results : The mean age and years of education of the study population was 67.0 and 7.7 years, and the types of chronic degenerative disease included musculoskeletal disorders(20.1%), cerebrovascular disease(17.1%), and diabetes(14.3%). The major forms of household living arrangement prior to admission were elderly alone(22.6%), and elderly couple(33.5%), while about half of them(55.5%) didn't want to live with their children id the future. Almost half were paying medication fees by themselves(46.6%). The level of actual intention of admission$(3.07{\pm}1.39)$ into a CNH was lower than that of interest$(3.22{\pm}1.33)$(p<0.01). Multiple analysis revealed that the intention of admission increased with decreasing number of future supportive persons$(\beta=-0.107)$, lower level of activity in daily life$(\beta=-0.447)$, and longer years of education$(\beta=-0.447)$ with 32.7% of $R^2$. As for the factors which determined the admission into a CNH, the fee and facilities were considered to be most important, and professional nursing and physician's care were the most desired services. In nomenclature, they preferred 'elderly hospital' or 'elderly health center' to CNH. Conclusions : Interest in CNH is increasing recently, but existing studies about patient experiences in CHN are still limited. This study may form a basis for future examinations of the needs and uses for CNH. Active financial support and public information are considered by the authors to be important factors for the induction of welfare services for the elderly, though CNH.

  • This study was tried to evaluate the level of completeness and the accordance in electronic medical records by comparing paper-based medical record in doctor's admission records, discharge summary, and nursing information records. Medical records of inpatients of neurology department that the 100 paper-based medical records in 2004 and 100 electronic medical records in 2006 were targeted. Existence of record items and doctor-nurse record accordance were evaluated in doctor's admission record, discharge summary, admission nursing information record, and discharge nursing information record. There were not any differences between electronic medical records and paper-based medical records in doctor's admission record and discharge summary. Electronic medical records had less missing records than paper-based medical records in admission and discharge nursing information records. Electronic medical records showed higher accordance than the paper-based medical record in doctor-nurse record generally, but there were statistically differences in only medication, allergy, smoking, and drinking (p<0.05). In this study, it was verified that the quality of electronic medical records are better than paper-based records in nursing information record and doctor-nurse record agreement.

  • The purpose of this study is to identify any differences in academic records of students after they got into the Korea National College of Agriculture and Fisheries through the entrance exam. The target group was the students of 1,035 who enrolled from the year of 2012 to 2014 by the exams respectively, and this study compared those first year's records. As a result, this study found that their academic achievements have no significant differences statistically. With regard to the result, we could recognize that the average achievements of students are arithmetically high, who were accepted by admission officer's interview(talented students of agriculture and fisheries) and regular admission procedure to which the scholastic test result is applied. Accordingly, it is more desirable that we should rather focus on measures to improve the admission procedure that could contribute to academic achievements of students who are mostly accepted through the nonscheduled admission. It is pointless to focus on discussion that the achievement of students selected by a particular procedure is low. That kind of criticism proved groundless. Secondly, the study of the correlation between their admission records and after admission records of the freshmen in 2012 shows that a significant difference does not exist whereas those of in 2013 and 2014 has a slightly different statistically, though a coefficient of correlation was a mere 0.17. It account for this result that KNCAF has increased the applied-rate of highschool transcript from 33.3% to 50.0.% in admission procedure from the year of 2013. However, lowering the applied-rate of farming and fishing background is not everything as we consider the graduates' easy settling into rural area. It is a well-known fact that after graduation, the majority of students who have applied for a grace period of the delay in performing the obligation of farming and fishing, and of students who have paid the school expenses back came from ones with no sufficient foothold. This means that we should formulate a supporting policy for the students to settle into rural area smoothly after graduation if we keep the regulation of lowing the applied-rate of farming and fishing.

  • This study aims to examine the differences between groups through the results of the core competency diagnosis, and to find out the differences in core competences depending on engineering education accreditation, gender, admission types. To this end, we analyzed the differences in K-CESA results on self-management capabilities, resources & information use, global competency, higher order thinking competency, and interpersonal competency in 2017 for the fourth graders of S University. An ANOVA of major field showed that the humanities had high overall competencies. The results of t-test of engineering students showed that accredited students had relatively low "flexibility" of their global competency, and that the "analysis" of their higher order thinking competency was relatively high. There were no statistically significant differences between groups depending on the admission types. Through these analyses, we presented suggestions such as the provision of specialized programs based on differences among different groups, the development of comprehensive thinking skills such as capstone design, the need to secure flexibility in engineering education accreditation, and the enhancement of female students' resources & information use.

  • The primary aim of this study was to compare responsiveness of self-report by worker and therapist-scored functional capacity instrument. Self-report and therapist-scored interval-level person measures and item difficulties were compared at admission and discharge. Therapist and worker ratings were collected on 230 clients from 27 rehabilitation sites using the newly developed Occupational Rehabilitation Data Base (ORDB) functional capacity instrument. ORDB comprises several subscales measuring relevant variables of "a return-to-work model" in work-related rehabilitation clinics. The functional capacity scale deals with 10 DOT job factors. The rating scale categories were 1-severely impaired, 2-moderately impaired, 3-mildly impaired, and 4-not impaired. Only data from clients with low back pain (n=98) with complete data (both admission and discharge scores) were used for the present study. Therapists and workers completed the functional capacity instrument at admission and discharge. Rasch analysis [1-parameter item response theory model (IRT)] was applied to calibrate item difficulty and person ability measure of therapist and workers ratings. Effect sizes for therapist and self-report ratings were slightly different, .69 and .30, respectively. Therapist and worker ratings were more consistent at discharge (r=.54) than at admission (r=.32). Workers have a tendency to be more severe in their ratings (show higher item difficulties) than therapists at admission and discharge. Therapists and workers report similar magnitudes of improvement following treatment program. These findings challenge the belief that injured workers may unreliable source for monitoring therapeutic outcomes. Self-report measures have the advantage of conserving therapist time for treatment (versus evaluation). While the therapist and self-report ratings are comparable at discharge, there is less consistency at admission. Comparable therapist-worker ratings may be achieved by controlling for rating severity using IRT methodologies.

  • Purpose: The aims of this study were to document our single-center experience with pediatric acute fulminant myocarditis (AFM) and to investigate its clinical features and short-term outcomes. Methods: We performed a retrospective chart review of all children <18 years old who were diagnosed with AFM between October 2008 and February 2013. Data about patient demographics, initial symptoms, investigation results, management, and outcomes between survivors and nonsurvivors were collected. Results: Seventeen of 21 patients (80.9%) with myocarditis were diagnosed with AFM. Eleven patients (64.7%) survived to discharge, and 6 (35.3%) died. Electrocardiography on admission revealed dysrhythmia in 10 patients (58.8%); of these, all 7 patients with a complete atrioventricular block survived. Fractional shortening upon admission was significantly different between the survivors (16%) and nonsurvivors (8.5%) (P=0.01). Of the serial biochemical markers, only the initial brain natriuretic peptide (P=0.03) and peak blood urea nitrogen levels (P=0.02) were significantly different. Of 17 patients, 4 (23.5%) required medical treatment only. Extracorporeal membrane oxygenation (ECMO) was performed in 13 patients (76.5%); the survival rate in these patients was 53.8%. ECMO support was initiated >24 hours after admission in 4 of the 13 patients (30.7%), and 3 of those 4 patients (75%) died. Conclusion: AFM outcomes may be associated with complete atrioventricular block upon hospital admission, left ventricular fractional shortening at admission, time from admission to the initiation of ECMO support, initial brain natriuretic peptide level, and peak blood urea nitrogen level.

  • Background: Functional capacity evaluations (FCEs) are designed to systematically assess the capacity to perform work-related tasks and to determine worker's ability to return to the previous job following work-related injuries. These evaluations may be rated either by clinician or worker. There has been a lack of consensus between the two scoring methods. Objects: This study aimed: 1) to confirm if the data are fit to the Rasch rating scale model and 2) to investigate the item-level concordance rate between the ratings of clinician and injured worker of the FCE. Methods: A cross-sectional study was conducted with a sample (n=124) of a rehabilitation program with the Occupational Rehabilitation Data Base for workers with low back pain. The functional capacity evaluation at admission and discharge was administered to clinicians and workers. The data were analyzed using both classical test theory-based Pearson's r and intra-class coefficient followed by item-level analysis with Rasch rating scale model. Results: All items of the FCE, except sitting items rated by clinician at admission and handling items rated by both clinician and worker throughout admission and discharge, were acceptable fit statistics with minor out of ranges for a misfit criterion. This may indicate that the items of the FCE overall fit to the Rasch rating scale model. Few problematic items responding differently to clinician and worker both at admission and discharge were detected with the differential item functioning analysis despite the excellent concordance rate using the two conventional statistics-sitting and handling items at admission and handling item at discharge. Conclusion: The item-level speculations using Rasch analysis of the FCE demonstrate that the ratings of clinician and self ratings of worker were psychometrically acceptable though there was an apparent discrepancy between the raters both at admission and discharge.
