Objectives : Basic life support (BLS) is considered one of the essential clinical skills medical students should master. Nevertheless, neither the current state of education nor the educative effect of and attitudes toward BLS in Korean medical students have yet been reported. The aim of this study was to examine the educative effect of BLS training for Korean medical students in terms of attitudes, knowledge, and skills. Methods : Surveys concerning attitudes toward BLS and its education, and tests for knowledge and scheme performance were conducted with 85 students in a college of Korean medicine under training for American Heart Association (AHA) BLS course for healthcare providers. Results : Before training, 70.6% of students answered they felt the necessity to be trained in the BLS course. The levels of confidence to perform and self-presumed knowledge on BLS were low at first. After training, however, the level of confidence and knowledge increased significantly. In the final test, the mean scores of written test and scheme performance significantly decreased, while the level of confidence didn't. Most of the participants answered they wanted to be re-trained under regular re-education system. Conclusions : To evaluate the current state of BLS education and its educative effect in Korean medical schools, it's required to expand the target of research to larger number of colleges and students over the country.

The aim of this study is to highlight the importance of the correct food choices and nutrition management through nutrition labeling and provide basic data for building a nutrition labeling system for Korean restaurants. In the study, a survey was conducted from February 5th to February 27th in 2010 involving adults over the age of 20 living in part of the Gyeonggi-do area. The data was used to analyze the general characteristics, the awareness of nutrition labeling and the nutrition labeling contents by using the SPSS 18.0 package program. Among the 268 people surveyed, the total number of women was greater (60.4%) than men (39.6%). The perception of the necessity of nutrition labeling was a relatively high score of 3.99 on a 1 to 5 scale and the motivation to utilize nutrition labeling scored 3.89. The study found that females perceived nutrition labeling to be more important than did the males. In addition, the perception varied according to the level of education and age. In conclusion, since customers have a high demand for nutrition labeling in Korean restaurants and are motivated to utilize labeling when eating-out is relatively strong, labeling would be a good educational tool for leading a healthy food life. Furthermore, since the study found that differences occur between nutrition labeling contents or nutrients according to general characteristics, food service companies might be able to gain benefits through differentiated nutrition labeling that is catered for their main customers.

Objective: Over the last several years, immunotherapy has become one of the most promising therapeutic options for cancer. This study aims to summarize the updates on cancer immunotherapy focusing on immune checkpoint inhibitors, such as programmed cell death-1 (PD-1), programmed death-ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitors, which have received attention as new anticancer therapeutic agents. Methods: A literature survey was carried out on PubMed to identify high-impact papers on cancer immunotherapy from 2010. The most recent data on clinical efficacy and safety have been included highlighting the response characteristics to recently approved immunotherapeutic agents. Results: In various cancers, immune checkpoints are a means for cancer cells to evade the immune system. Furthermore, CTLA-4 and PD-L1 can be overexpressed, allowing malignant cells to evade T-cells. Numerous clinical trials have been performed to seek appropriate indication of these products in various cancer types. Among them, the most conspicuous types are melanoma, non-small-cell lung cancer, and head and neck cancer. The approval of ipilimumab by Food and Drug Administration (FDA) commenced a new era of cancer immunotherapy. This was followed by the approval of nivolumab and pembrolizumab. Currently, combination therapies are being investigated for various cancer types. Conclusion: In this study, we reviewed recently reported scientific and clinical evidence for currently approved immune checkpoint inhibitors. Although these novel checkpoint inhibitors are ever evolving for cancer therapies, there exist limitations that need to be overcome, indicating the necessity for further studies aiming to improve their efficacy, toxicity, and cost.

A finite element nonlinear stress-deformation model with multi-interface element is applied to the stability analysis of waste landfill slope. Strength parameters of waste and geosynthetic materials are obtained from the triaxial test of waste and the direct shear test of geosynthetics, respectively. The landfill models used for the numerical models are fit to regulations of the Korean waste management law. The results of the strength tests showed linear behavior for the waste and nonlinear behavior for the eosynthectic materials. The stability analysis with multi-interface element for the geosynthetic materials in the liner system showed large shear stress and slippage at the boundary of the foundation and the slope of the waste fill. This analysis verified the necessity of multi-interface analysis for waste landfills with composite liners.

Recently, Seoul residential real estate market showed a big change, especially in 2007. The residential property price in Seoul had been mainly affected by 5 provideces: Kangnam-gu, Seocho-gu, Songpa-gu, Gangdong-gu and Yangchun-gu, but these providences started to show the decrease in price while the other providences ironically showed the opposite direction. Therefore, this project was derived from this phenomenon recognition and the necessity as the new market trend requires. The pre-research was carried out with the point of social-population academic view, but this project provides the analysis on the new market trend by simplifying the complex valuation indexes, originated from the pre-research. In result, the aspects of the change could be categorized into time-manner classification and territorial-manner classification, in cope with the change in the satisfaction degree on the residential environment and the selection tendency of the residential property. Based on the the moving-preferred area criteria, the territorial classification was categorized into 3 areas: 5 providences, which showed the initial decrease in real estate price (area 1), the other Kangnam area (area 2), and Kangbuk area (area 3). The result illustrated the reasonable change in the satisfaction degree on the residential environment and the selection tendency of the residential property. This project was able to reach the following conclusion : Firstly, the housing development planning should be devised by the residential environment, including the view and the natural environment, not by the area. Secondly, the housing development planning in the other Kangnam area (area 2) and Kangbuk area (area 3) should embrace the business function, not the housing development only. Last, the housing development planning in Kangbuk area (area 3) should be able to enhance education and culture function and be connected by various transportation system. This project analyzes the change in the satisfaction degree on the residential environment and the selection tendency of the residential property. Thereafter, this project has the purpose of providing the aid in understanding of the basis of housing development information.

Over a period of several years there have been a number of queries raised with the ICC Banking Commission as to the determination, by banks, of what is an "original"document under a letter of credit and the necessity, if my, for such a document to be so marked. So, the ICC Banking Commission Decision on original documents was sent to members in July. This Decision emphasizes the need to correctly interpret and apply sub-Article 20(b) of UCP 500. Consequently, about Hand signed documents, Facsimile signed documents, Photocopies and Telefaxed presentation of documents, Banks examine documents presented under a letter of credit to determine, among other things, whether on their face they appear to be original. Banks treat as original any document bearing an apparently original signature, mark, stamp, or label of the issuer of the document, unless the document itself indicates that it is not original. Accordingly, unless a document indicates otherwise, it is treated as original if it : appears to be written, typed, perforated, or stamped by the document issuer's hand; or appears to be on the document issuers original stationery; or states that it is original, unless the statement appears not to apply to the document presented (e.g. because it appears to be a photocopy of another document and the statement of originality appears to apply to that other document).document).
