In various applications of queueing systems, admission control is often employed. It is known that the threshold-type of admission control is optimal in many practical applications despite its simplicity. However, determining the optimal threshold value is hard in general, because analytical expressions for the stationary queue length distributions are not easily available in most queueing systems. In this paper, to quickly determine the optimal threshold value under threshold-type admission control, we develop a concurrent simulation technique, which can save large amount of CPU time required in simulation, compared to the standard simulation procedure.

For axial-type turbines which operate at partial admission, a performance prediction model is developed. In this study, losses generated within the turbine are classified to windage loss, expansion loss and mixing loss. The developed loss model is compared with experimental results. Particularly, if a turbine operates at a very low partial admission rate, a circular-type nozzle is more efficient than a rectangular-type nozzle. For this case, a performance prediction model is developed and an experiment is conducted with the circular-type nozzle. The predicted result is compared with the measured performance, and the developed model quite well agrees with the experimental results. So the developed model could be applied to predict the performance of axial-type turbines which operate at various partial admission rates or with different nozzle shape.

Purpose: This study was performed to identify the effect of admission type on college adaptation and academic achievement in one nursing school in order to refine the entrance selection system. Methods: Subjects were 405 nursing students (female : male = 385 : 20, first grade = 155, second grade = 138, third grade = 112). They were given the Student Adaptation to College Questionnaire (SACQ) purchased from Western Psychological Service. SACQ is composed of 67 questions and subdivided into 4 subcategories: academic adjustment, social adjustment, personal-emotional adjustment, and attachment. Student college adaptation scores and academic achievements were analyzed with reference to the entrance selection system (rolling admission vs. regular admission) by SPSS 22.0. The rolling admission system recruited students based on high school records only while the regular admission system was based on both high school records and the College Scholastic Ability Test (CSAT). Results: Total College adaptation score, personal-emotional adjustment score, and academic achievement were higher in regular-admission students than in those admitted through rolling admission. Academic achievement for first-grade students was higher in regular-admission students than for those admitted through rolling admission, But the difference in academic achievement became null as students were promoted to the second and third grades. Conclusion: Students recruited using both high school records and the CSAT showed better college adaptation and higher academic achievement.

As the dropout rate of university students is gradually increasing, the studies on exploring the status, characteristics, reasons, and countermeasures of dropout of university students are currently grabbing high attention. This paper analyzes the relationship between the admission types and dropout of university students, mainly focused on engineering students. The analysis shows that the dropout rate of engineering students admitted through the scheduled-time admission procedures is quite higher than that of students admitted through non-scheduled-time admission procedures, the dropout rate of engineering students admitted from the vocational high schools is higher than that of students from the academic high schools, and the dropout rate of engineering students admitted from the liberal art high school tracks is higher than that of students from the natural science high school tracks. From the results, we could find out that student-support programs need to be carefully provided for the engineering university students according to their admission types and underlying backgrounds.

Objectives : The purpose of this study is to analyze the proportion of admission via the emergency room(the rest is ER) in an emergency medical center and to examine the factors related to admission. Methods : This study used 2005 National Health Insurance claims data for admitted patients of 112 hospitals having emergency medical centers in Korea. The study sample had 2,335,610 patients. The data was classified into emergency admission and non-emergency admission. To investigate the factors affecting the type of admission, the following were included as independent variables: type of health assurance_(national health insurance beneficiaries or medical aid beneficiaries), demographic characteristics_ (sex, age), cause of admission_ (disease or injury), whether an operation was performed or not, DRG severity level, the number of beds, and the location of the hospital. Data were analyzed using the Chi-square test for the differences in emergency admission rates for each variables, and multiple logistic regression analysis was used for identifying the factors affecting admission type. Results : The proportion of admission via the ER accounted for 40.6% of the total admission among hospitals having emergency medical centers. The risk of admission via ER was relatively high for patients who were male, the aged, the injured, the surgical patients, the patients having more severe symptoms, and the patients admitted the hospitals located in metropolitan areas, and the patients admitted the hospitals having 300-699 beds. Medical aid patients were more likely admitted through the emergency room than health insurance patients after other variables ware adjusted. Conclusions and Discussion : We analyzed the proportion of admission via the ER for the total admission rate of hospitals having an emergency medical center in Korea. And we explored the factors related to admission via the ER. This proportion may be used as an indicator of the adequacy of medical utilization or low accessibility to hospitals of patients with low socioeconomic status.

Purpose: The purposes of this study were to examine the relationships among activities of daily living, self-efficiency, nursing home care quality and nursing home adaptation, and to identify the influencing factors of nursing home adaptation in nursing home residents. Methods: The study employed a descriptive correlational design. The data were collected from 148 older adults without dementia by interview from six nursing homes in three cities from February 1, 2008 to February 28, 2008. Results: Levels of nursing home adaptation in older adult residents were different by type of decision maker of nursing home admission, reason of nursing home admission, type of payment and length of nursing home stay. The nursing home adaptation was significantly correlated with self-efficiency and nursing home care quality. The strongest predictor of nursing home adaptation was type of decision maker of nursing home admission followed by the self-efficiency. Conclusion: The study suggested that during the decision making period of nursing home admission, older adults should have enough time and careful considerations of their families to decide by themselves in positive ways. Nursing home staff should be able to identify reasons of nursing home admission and demands or expectations of older adults and their families.
