This study aims to develop the Korean types of continuing care retirement communities (CCRCs). CCRC is well evaluated as a residence that applies aging-in place concept, which is ideal for senior housing. Recently, in USA the CCRCs in which the increasing seniors' population and older households are guaranteed to get continuous protection without moving regardless of their deteriorating health are increasing. In Korea, CCRCs have emerged but not well developed in status quo. We conducted case study using three facilities located at Seoul and its suburbs in Korea to compare five categories such as application of 'aging in place' concept, location, architectural features, services or programs, and management. This study is expected to be used basic materials for CCRCs' complex and architectural planning, management strategies, and services or programs.

In letter of credit arrangements, the issuing bank nominate a reimbursing bank which serves as a source of funds payment to the beneficiary. The reimbursing bank could be 3rd party bank or the issuing bank itself. In view of working capital requirements, most beneficiary want to get export proceeds in advance through nominated banks and therefore letter of credit usually permit the beneficiary to negotiate drafts, accompanied by required documents, to nominated bank. If the credit is available with the nominated bank, there must be a reimbursement instruction in the credit, because in this method of availability the issuing bank is obliged to reimburse the nominated bank if that bank acts on its nomination There are legal relationship among issuing bank, nominated bank and reimbursing bank with regard to reimbursement activities. Related rules are UCP and URR and UCC (in case of USA). Korean exporters and bankers do not appear to know well the role of reimbursement and usage. 3 cases (court case + ICC Opinion + bad practices) were employed to study the reimbursement mechanism and suggest better usages. The beneficiary is strongly recommended to know the benefit of reimbursement claim from independent reimbursing bank. The benefits include speed payment (thereby saving finance costs) and safe funds (in case of stop payment by the issuing bank right after the proceeds are reimbursed). And further the beneficiary banks (being nominated or claim banks) are also recommended to take advantage of the 3rd party reimbursement in view of the cases illustrated.

This study aimed to develop Korean types of the university-based continuing care retirement community. CCRCs (Continuing care retirement communities), where senior residents are guaranteed to get continuous cares without moving out even under their deteriorating health condition, has been identified as the appropriate residences that can accommodate aging-in-place needs. Aging-in-place may be ideal for the increasing senior population and older households. Recently in the United States, as many retirees looked for intellectually and physically active environments that also offer intergenerational programs, university-based retirement communities (UBRCs) became popular and their number reached 60 campuses nationwide. This numbers is expected to grow significantly over the next two decades. We conducted case studies that targeted two representative UBRCs and identified four categories of main features. They were general characteristics, architectural features, services or programs, and management system. This study result highlighted key features of the UBRCs that can be the foundation for the future UBRCs development in Korea.

This paper was designed to investigate emission characteristics of regulated pollutants (CO, HC, NOx and PM) from 134 diesel and gasoline passenger cars based on emission standards according to fuel additives. The experiments using chassis dynamometer were conducted under NEDC and CVS-75 modes. Comparison for fuel additive management and test between Korea, USA, EU and Japan, Korea was more strict than others. The fuel additives of this study was satisfied within fuel manufacturing standards. For with/without fuel additives according to diesel emission standards, NOx of EURO 4 and EURO 5 showed a relatively similar tendency. In the case of PM reduction rate, EURO 5 was over 20% increased than EURO 4. In the case of standard deviation/average ratio for gasoline vehicles, variation interval was big for LEV 23.3~58% and ULEV 31.6~56.4%. Following the imposition of stricter regulations (EURO 5 and ULEV), difference rate for standard deviation was big. Especially, in the case of diesel vehicles, difference rate for NOx 68% and PM 48% was most big. The results of present study will be of assistance in completing the legislative process and will provide basic data to set up emission standards for fuel additives in Korea.

There are many researches to make low-energy building. Lots of them focus on facility systems and insulation performance of building materials. However, not only systematic solutions but also approaches in early design stages are important to reduce energy consumption. Using BIM(Building Information Modelling) is considered as an effective and efficient way to simulate building energy and decide alternatives than traditional energy simulation because BIM based energy simulation makes to reduce much time for energy modeling. This study focuses on development of optimized geometry for super tall office buildings in Seoul, Korea. Specifically, length to width ratio and building orientation are main topics of this study because these two topics are the most basic and preceding factors deciding mass design. In this study, Revit MEP 2011 and Ecotect Analysis 2011 are used to make case models and calculate energy load in early design stages. Energy properties of material abide by Korean Standards for Energy Conservation in Building, Korean Guideline for Energy Conservation in Public Office and ASHRAE Standard in USA. This study presents best length to width ratio of plan and optimized orientation by evaluating the case models. Furthermore, this study suggests what should be considered for each case to decrease energy load.

Stochastic simulation of hydrologic data has been widely developed for several decades. However, despite the several advances made in literature still a number of limitations and problems remain. In the current study, some stochastic simulation approaches tackling some of the existing problems are discussed. The presented models are based on nonparametric techniques such as block bootstrapping, and K-nearest neighbor resampling (KNNR), and kernel density estimate (KDE). Three different types of the presented stochastic simulation models are (1) Pilot Gamma Kernel estimate with KNNR (a single site case) and (2) Enhanced Nonparametric Disaggregation with Genetic Algorithm (a disaggregation case). We applied these models to one of the most challenging and critical river basins in USA, the Colorado River. These models are embedded into the hydrological software package, Pros and cons of the models compared with existing models are presented through basic statistics and drought and storage-related statistics.

Purpose: This study aimed to introduce active learning methods, including flipped, case-based, and team-based learning in an electrocardiography (ECG) course and to investigate outcomes and satisfaction with these methods. Methods: To identify the learning effect of active learning, pre-and post-academic self-efficacy was compared between the experimental and control groups. In the experimental group, pre-and post-knowledge and clinical performance regarding ECG were also assessed. In addition, class satisfaction was investigated after application of active learning methods in the experimental group. Data were collected from 84 paramedic students and analyzed using SPSS 22.0 (IBM, Armonk, NY, USA). Results: The experimental group showed significant improvement in post-academic self-efficacy and knowledge. The experimental group also showed high clinical performance (9.83 out of 10 in ECG checking ability and 9.63 out of 10 in ECG reading ability). The mean satisfaction score was 4.23 out of 5 (responses based on a Likert scale) in the experimental group. Conclusion: Active learning in an ECG course was found to be highly effective and satisfactory. Furthermore, paramedic students can enhance their accountability and judgement with team-based learning through free engagement in discussion.

I. Purpose Confirming an error to be able to break out in a method to move couch manually while operator sees the skin marks on patient in case of curing head who got 2 targets adjoined, so we analyze coordinates price of couch, evaluate reproducibility and precision of change movements between targets. II. Materials and Methods In radiotherapy, for confirming errors in manual movements by operators by exchanging between two targets to treat patient head, we read coordinates price(vertical, longitudinal, lateral three directions of couch) shown on a monitor of LINAC( CL 2100, Varian, USA) in order to evaluate accuracy about the length that moved in time for moving couch manually. After reading movement length of coordinates recorded in three directions of all treatment, we compared distance between targets recorded in RTP(Pinnacle, ADAC, USA) with reading coordinates price of couch, setting actually done the same patient for ten times, coordinates were recorded, treated for evaluating averages and degrees of errors and standard deviations. III. Results In method to confirm skin marks of patient by operators' view and to move couch manually, average standard deviations of movements between two targets are vertical 1.4mm, longitudinal 0.9mm, lateral 2.2mm in each direction. As for the error in straight dimension, it is about 3.6mm averages and 5.1mm maximum. The average of errors in each directions was vertical 1mm, longitudinal 0.7mm, lateral 2.7mm. The greatest error broke out in lateral direction with $25\%$ of all cases ; to exceed an error average. IV. Conclusions If operators moved manually couch for changing target points, errors about 3.6mm average degrees occur. It is important that operators confirm the errors prices of actual couch coordinates for asking a correct movement between the targets adjoined each other ; in case of treatment demanding high precision like 3D conformal therapy or IMRT. Therefore, if we apply couch coordinates confirmation to reproducibility and to precision evaluation of treatment, it's expected that we can execute high-quality radiotherapy.
