The study seeks to identify factors affecting the choice of a university by first-year Business Administration students in Vietnam. Probability sampling is using Stratified sampling of 500 students from five private universities in Ho Chi Minh City surveyed by convenience sampling. This paper employs mixed research methods - measuring Cronbach's Alpha, EFA, Regression and using PATH model - to test the hypotheses of the research model. The results of the study identify five factors: Prestige, Geographical location, Facilities, Attractiveness of the field and Media. All these factors have a positive influence on the standing of the university brand. It means that the higher the Prestige, Geographical location, Facilities, Attractiveness of the field and Media, the higher the university brand. The results indicate that Geographical location is the most influential factor to enhance the private university's brand. Bringing Geographical location is, thus, advisable to enhance a university standing. The brand plays a determining role in students' trust when selecting a university. Media is still the top concern of new students when they choose to study at a university. Media still remains an important consideration for new students when choosing a university. So, this factor should be utilized by universities to enhance their attractiveness.

This study analyzes Korea's Free Economic Zone (FEZ), by particularly focusing on Incheon and Busan-Jinhae zones, using the Analytic Hierarchy Process (AHP) method and a questionnaire survey analysis. The study compares important selection criteria and satisfaction of resident companies in Incheon and Busan-Jinhae FEZs. The findings are as follows. First, the AHP method results suggest that companies in both Incheon and Busan-Jinhae FEZs are affected by location, economic society, and policy. In subordinate determining factor for land, it is ordered by ease of gaining land, inexpensive rental fee in Incheon and by convenient access to close markets and inexpensive rental fee in Busan-Jinhae. Second, the questionnaire survey results suggest high adjacent market size and easy access in Incheon FEZ and sound logistics infrastructure in Busan-Jinhae FEZ. For this reason, Incheon has a high value of logistics infrastructure and potential market near metropolitan area and Busan-Jinhae, has a high value of transportation Infrastructure near industrial district. These findings will contribute to policy data for activating and promoting the Free Economic Zone.

In this paper we describe Wilcoxon test and T-test that are well-known in two-sample location problem for detecting edges under different window configurations. The choice of window configurations is an important factor in determining the performance and the expense of edge detectors. Our edge detectors are based on testing the mean values of local neighborhoods obtained under the edge model using an edge-height parameter. We compare three window configurations based on statistical tests in terms of qualitative measures with the edge maps and objective, quantitative measures as well as CPU time for detecting edge.

In emergency rescue situations, the localization accuracy of the rescue requestor is a very important factor in determining the success or failure of the rescue. Indoors where Global Navigation Satellite System (GNSS) is not operated, there is no choice but to use Wi-Fi or LTE signals. However, the performance of the current emergency rescue system utilizing those RF signals is exceedingly low. In this study, the effectiveness of the surface correlation technology using the accumulated signal pattern of RF signals was verified in relation to the emergency localization technology. To validate the proposed system, we configured and tested an emergency rescue scenario in multi-floors building. When the emergency rescue was requested, it was confirmed that the initial localization error was large owing to the short length of the accumulated signal pattern. However, the localization error decreased over time, which eventually led to the accurate location information being delivered to the rescuer.

Introduction : The management of chordomas and chondrosarcomas in the skull base is difficult due to the critical location, locally aggressive nature, and high recurrence rate. The authors present the effectiveness of surgical removal and radiation therapy on survival and tumor recurrence. Material and Methods : Thirty cranial base chordomas and chondrosarcomas from 23 patients(14 patients with chordomas and 9 patients with chondrosarcomas) were operated in our institution between 1985 and 1998. There were 15 men and 8 women, with a mean age of 40.7 years. The largest diameter of tumors ranged from 15 to 70mm (mean 41.5). The extent of surgical removal was subtotal or total in a half(15 operations). In nineteen operations, tumors were removed by conventional approaches and skull base approaches were applied in 11 operations. Postoperative radiation therapy was performed in 16(70%) patients. The mean duration of follow up is 50 months(1- 156 months). Results : The 3- and 5-year survival rates(YSR) of overall patient are 75% and 67%, respectively. The analysis showed that 1) skull base approach to chordomas and chondrosarcomas showed a tendency to remove more portion of the tumors(p＝0.058) but leave more frequent incidence of new deficits(p＝0.047) : 2) larger tumor diameter af-fected the extent of removal(p＝0.028) : 3) the extent of removal seemed to be the determining factor for overall survival and recurrence-free survival(the 5-YSR and RFSR of subtotal or total removal group are 92% and 80% vs. 40% of partial removal or biopsy group) : 4) conventional radiation therapy improved patient survival(5-YSR of patients who received RT is 76% whereas 5-YSR of those who didn't receive RT is 43%) but failed to prolong long-term recurrence-free survival. Conclusion : The extent of removal and postoperative radiation therapy are determining factors of patients' survival in skull base chordomas and chondrosarcomas. However, none of these factors significantly influenced the survival in multivariate analysis. Aggressive surgical removal of more than subtotal resection combined with postoperative radiation therapy seems to be the choice of therapy in the management of these tumors.
