  • Owing to the digital revolution, Internet Commerce and Electronic commerce, revolutionize the way of doing business and making payment. The entrance of the Internet has a prominent for spread of Electronic Commerce and those phenomenons will result in paperless trading and cashless trade. By virtue of Internet, an increasing share of business transactions occurs online. Electronic payment is essential for the smooth progress of the electronic commerce as electronic payment plays the important role in the electronic commerce, that is, the value transfer restyling from the electronic commerce. Traditionally international settlement systems such as letters of credits, remittance and documentary collections operated as important and poplar method of payment, Now, information technology has made it possible to pay for the sale of goods and services over the internet. In international trade, there are service providers (bolero, TradeCard, BeXcom) to settle payment electronically through the Internet. The purpose of this study is to Conduct comparative analysis with approach manner functional respect systematic respect, role. It is shown which the Electronic payment system is better. In this study, the author attempts to find the problems is (bolero, TradeCard, BeXcom) and solutions in switching from the documentary payment system to the electronic one. This conclusion of this study can be summarized as followings. In resoect of the law, bolero should seek to prevert the users from being treated unfairly due to multilateral agreement on Rulebook. TradeCard, BeXcom do not have the proper law that users are governed. so far as the practice problems concerned, stability of computer's operation and security of message interchange should be warranted and improved continuously. Through the standardization of the electronic document and the development of software, the examination of the shipping occuments must be done automatically. Bolero should induce more banks to take part in Bolero, and make the carrier the cost and time in managing the traditional document which will be used for the time being. In respect of information technology and security, to deduce the risk in the electronic settlement system and positively uses the global authentication guideline(Identrus).

  • The concept of natural grouping of plant designated as the "Amentiferous" is no longer given serious credence, and many of the families included in this grouping have been dispersed in diverse order. Because a review of taxonomic treatments of amentiferous taxa reveals diverse classifications, it has become necessary to investigate new characteristics and attempt to determine the significance of these characteristics in terms of amentiferous taxonomy. Protein analyses by isoelectrofocusing(IEF) and rocket immunoelectrophoresis(RIE) have proved to be useful in the delicitation of Quercus taxa using pollen extracts from selected taxa. When Quercus pollen extracts were separated by electrophoresis based on their isoelectric points in a stable pH gradient and substrates for estrase activity were stained, ten bands were revealed between pH 5-14. Within Lepidobalanus grouping, a great diversity in the pollen protein zymograms was observed with some segregation corresponding to the designated taxonomic sections. Two taxa of Cyclobalanopsis produced a zymogram that is somewhat similar to taxa included within the section Prinus of Lepidobalanus, and less similar to taxa within the section Cerris of the same subgenus. Three tested taxa of the Cerris are in the similar zymogram each other, being segregable from the taxa of Prinus. Quantitative and qualitative analyses for serological relationships within and among th Quercus were also employed. To calculate the degree of protein similarity, total rocket heights obtained from RIE provided an index of serological correspondence(SC). It is reconfirmed that the Quercus is distantly separated from the Fagus according to SC. Comparative data from rocket number and SC in the tested taxa of Quercus also indicate that Lepidobalanus is separable from Cyclobalanopsis. Within the Lepidobalanus Q. acutissima and Q. acutissima x variabilis are almost homogeneors and distinguishable from the other tested taxa of same subgenus. Although the number of taxa tested has been limited, the overall serological evidence best reflects the classification proposed by Redher(1940) and Melchior (1964), having the genus Quercus subdivided into three subgunera: Erythrobalanus, Lepidobalanus, and Cyclobalanopsis.alanopsis.

  • Objective : Endovascular treatment (EVT) outcomes for acute M2 segment of middle cerebral artery occlusion remains unclear because most results are obtained from patients with large artery occlusion in the anterior circulation. The objective of this study was to assess procedural outcomes for acute M2 occlusion and compare outcomes according to thrombus location (M1 vs. M2). Methods : A systematic review was performed for online literature published from January 2004 to December 2016. Primary outcome was successful recanalization rate and symptomatic intracranial hemorrhage (S-ICH) after the procedure. A fixed effect model was used if heterogeneity was less than 50%. Results : Eight articles were included. EVT showed successful recanalization rate of 69.1% (95% confidence interval [CI], 54.9-80.4%) and S-ICH rate of 6.1% (95% CI, 4.5-8.3%). The rates of good clinical outcome at 3 months and mortality were 59.4% (95% CI, 49.9-68.2%) and 14.9% (95% CI, 11.4-19.3%), respectively. According to thrombus location (M1 vs. M2), successful recanalization (odds ratio [OR], 1.539; 95% CI, 0.293-8.092; p=0.610) and S-ICH (OR, 1.313; 95% CI, 0.603-2.861; p=0.493) did not differ significantly. Good clinical outcome was more evident in M2 occlusion after EVT than that in M1 occlusion (OR, 1.639; 95% CI, 1.135-2.368; p=0.008). However, mortality did not differ significantly according to thrombus location (OR, 0.788; 95% CI, 0.486-1.276; p=0.332). Conclusion : EVT seems to be technically feasible for acute M2 occlusion. Direct comparative studies between EVT and medical treatment are needed further to find specific beneficiary group after EVT in patient with M2 occlusion.

  • This study aims to examine the difference in the level of housing cost burden and the factors affecting housing cost burden between permanent rental housing and purchased rental housing residents in Seoul. We used the 2017 SH Public Housing Resident Survey and employed t-test and multiple regression analyses. The empirical analysis shows that the level of housing cost burden is greater for permanent rental housing residents than purchased rental housing residents. Also, income level, age, and whether receiving housing benefits are the factors affecting housing cost burden among permanent rental housing residents while income level and housing size are the factors affecting housing cost burden among purchased rental housing residents. The findings suggest that there should be a more systematic review regarding housing affordability among those living in different types of public housing toward housing welfare. In addition, there should be differential approach to enhance housing affordability between permanent and purchased rental housing residents.

  • Objective : Preoperative transarterial embolization (TAE) of tumor feeders in hypervascular spine metastasis is known to reduce intraoperative estimated blood loss (EBL) during surgery. The effect of TAE varies for several reasons, and one controllable factor is the timing between embolization and surgery. However, the adequate timing remains unclear. This study aimed to evaluate the timing and other factors that reduce EBL in spinal metastasis surgery through a meta-analysis. Methods : A comprehensive database search was performed to identify direct comparative studies of EBL stratified by the timing of surgery after TAE for spinal metastasis. EBL was analyzed according to the timing of surgery and other factors. Subgroup analyses were also performed. The difference in EBL was calculated as the mean difference (MD) and 95% confidence interval (CI). Results : Among seven studies, 196 and 194 patients underwent early and late surgery after TAE, respectively. The early surgery was defined as within 1-2 days after TAE, while the late surgery group received surgery later. Overall, the MD in EBL was not different according to the timing of surgery (MD, 86.3 mL; 95% CI, -95.5 to 268.1 mL; p=0.35). A subgroup analysis of the complete embolization group demonstrated that patients who underwent early surgery within 24 hours after TAE had significantly less bleeding (MD, 233.3 mL; 95% CI, 76.0 to 390.5 mL; p=0.004). In cases of partial embolization, EBL was not significantly different regardless of the time interval. Conclusion : Complete embolization followed by early spinal surgery within 24 hours may reduce intraoperative bleeding for the patients with hypervascular spinal metastasis.

  • Since 2011, after beginning of the systematic study on STEAM education, South Korea has developed a number of related programs. At this point we see that this is the time to clarify the challenges. The purpose of this study is to clarify the characteristics of their education through the review of many domestic and foreign papers in order to propose the challenges of STEAM education of Korea. The results are as follows. First, the course of integration cannot be separated by the difference in superiority but should be separated in accordance with the purpose of integration. Second, curriculum integration such as STEAM education is characterized by the emphasis on horizontal linking than vertical depth fusion. Accordingly, the content knowledge and vertical linkages are inevitably weakened. In order to overcome this problem, the key concepts and features that were emphasized in the previous curriculum need to also be emphasized in STEAM training, and the comparative study on the core concept and function of each subjects should be preceded. Third, after looking upon the current situation of our country's fusion research and talent training, the limits and the challenges that need to be overcome has been suggested. Fourth, with the basis on research results, we offered an example of the approach on STEAM education which is applicable to the current situation and proposed the challenges and implications that need to be addressed in the STEAM education of Korea in educational contexts such as curriculum, teaching and learning, and evaluation.

  • Purpose: To evaluate and update evidence for prognostic effects of kidney-sparing (KS) management and nephroureterectomy (NU) for upper tract urothelial carcinomas. Materials and Methods: Pubmed, Embase and the Cochrane Library were retrieved for the identification of comparative studies of kidney-sparing procedure and nephroureterectomy for upper tract urothelial carcinoma prior to December 2014. The data were extracted independently by 2 reviewers and the quality of the included studies was assessed. Review Manager 5.3 and STATA 13 were used to perform the meta-analysis. Results: Twenty-three observational studies including 1,587 KS and 3,996 NU were evaluated. The results of the meta-analysis showed that nephroureterectomy had no significant benefit with regard to intravesical recurrence (IRFS), metastasis (MFS), cancer specific survival (CSS) and overall survival (OS) except the total tumor recurrence (RFS) when compared with kidney sparing management. The respectively pooled outcomes were HR 1.36 (0.69-2.68, P=0.38) for IRFS, 1.09 (0.59-2.01, P=0.78) for MFS, 1.17 (0.77-1.79, P=0.47) for CSS, 1.50 (0.90-2.48, P=0.12) for OS and 1.61 (1.03-2.51, P=0.04) for RFS. Conclusions: On the whole, kidney-sparing management had equivalent prognostic effect on upper tract urothelial carcinoma as the standard nephroureterectomy except in tumor recurrence. However, the results should be interpreted with caution for lack of stage and grade stratification and multi-center randomized controlled trials are still needed to verify our results.
