Purpose: The purpose of our study was to introduce an oath and ethics code for emergency medical technicians (EMTs). Methods: The proposed oath and ethics code for the EMTs was evaluated using a modified Delphi technique. This oath and ethics code was presented at Korean association of emergency medical technician conference and was revised by experts in emergency medical services. Results: We examined the ethics codes for other allied healthcare professionals regarding the topics of human rights, health promotion, acting as an advocate, ethics, cooperation, observance, human rights, right to know, self-determination, confidentiality, and professionalism. These elements are reflected in our proposed oath and ethics code for EMTs. Conclusion: The proposed oath and ethics code would raise the professional status of EMTs.

The purpose of this study is analyzing the prescriptions of American codes for straw bale structures and proposing the legislation direction of Korean building code. The process of this study is as follows: (1) To set up the legislation direction of straw bale code of Korea, this study investigated the current state and features of straw bale houses in Korea, and looked into the worldwide status of straw bale codes and permitting. (2) To provide basic data for the legislation of Korean straw bale code or guideline, this study analyzed American codes for straw bale structures like the Tucson/Pima County Arizona Building Code Appendix Chapter 72 - Straw-Bale Structures, California State Guidelines for Straw-Bale Structures, New Mexico Standards for Non-load Bearing Baled Straw Construction, Oregon State Residential Code Appendix M - Straw-Bale Structures and so on. The analysis items are the scope of rule application, material specifications, requirements for straw bale walls/foundations and construction requirements.

The utilization of gas as ship fuel requires a new set of regulations by IMO and society of classification. Maritime Safety Committee(MSC) and the subcommittee Bulk-Liquids and Gases(BLG) in IMO developed "Interim Guidelines on Safety for Natural Gas-fueled Engine Installation in Ships(Res.MSC.285(86))" for the use of natural gas in internal combustion engine. According to the requirement of Res.MSC.285(86) for natural gas-fueled engine installations in ships, several parts of ships should follow safety criteria in terms of Fuel bunkering, Gas safe Machinery spaces, Gas Fuel Storage and etc. In this thesis, details of the IGF code shall be described and development of the IGF code in IMO shall be illustrated.

In this paper, a new multi-group neutron-gamma transport calculation code system STRAUM-MATXST for complicated geometrical problems is introduced and its development status including numerical tests is presented. In this code system, the MATXST (MATXS-based Cross Section Processor for S_N Transport) code generates multi-group neutron and gamma cross sections by processing MATXS format libraries generated using NJOY and the STRAUM (S_N Transport for Radiation Analysis with Unstructured Meshes) code performs multi-group neutron-gamma coupled transport calculation using tetrahedral meshes. In particular, this work presents the recent implementation and its test results of the Krylov subspace methods (i.e., Bi-CGSTAB and GMRES(m)) with preconditioners using DSA (Diffusion Synthetic Acceleration) and TSA (Transport Synthetic Acceleration). In addition, the Krylov subspace methods for accelerating the energy-group coupling iteration through thermal up-scatterings are implemented with new multi-group block DSA and TSA preconditioners in STRAUM.

컴퓨터 기술의 확산과 더불어 분산 컴퓨팅 환경에서 이동에이전트 코드의 이동성은 유연성이 있어 인터넷상에서 분배된 애플리케이션들을 설치하는데 사용되고 있다. 동시에, 이동에이전트의 이동코드를 전송하고 멀리 떨어진 곳의 호스트로부터 수신할 수 있는 능력을 가지고 있어서 에이전트가 실행되는 호스트 시스템의 실행 환경은 에이전트의 코드와 이를 실행할 수 있는 실행 환경에 접근을 해야 함으로 악의적인 행위들로부터 에이전트의 위조, 변조, 잘못된 실행을 방지하기가 매우 어렵다. 따라서 본 논문은 암호화된 에이전트의 코드와 상태 추적을 통하여 여러 악의적인 행위로부터 에이전트를 보호할 수 있도록 하는 메카니즘을 제안한다 제안한 메카니즘을 통해 이동에이전트가 보호되는 과정을 통해서 안전성을 증명하였다.

Postal code is essential for improving efficiency of mail sorting. The Korean postal code, which is introduced in 1970 and had been reformed two times, has controversial issues because of changed postal environments such as modification of administrative districts and logistical transformation into a hub-and-spokes structure. In this study, we propose several improvement and evaluation methods in order to prepare an alternative plan of postal code system. After performing status analysis, we define the customers of postal code and analyze the requirements of them. The 6 proposed new postal code systems are based on each customer groups’ requirements. To evaluate the new systems, we develop several quantitative and qualitative indexes and make a survey of postal experts. Besides, we evaluate the influence of them to the postal environments including delivery sequence sorting process.

A complete code-package for gyrotron simulation to analyze its performance is under development in UNIST, Korea. We first time report the present status of the code-package named as UNIST Gyrotron Design Tool (UGDT). It can perform design simulations for gyrotron's interaction cavity, RF window, and the essential mode calculations including the study of mode competition. We will discuss about its salient features, theory, numerical implementation, and its calculation result for 95 GHz UNIST Gyrotron. Moreover, we will validate its capability to perform the mode competition calculation for fundamental and second harmonic modes.

The paper discusses results of recent international intercomparison exercises on internal dose assessments, status of up to date internal dosimetry methods and the radiological legislation developed and implemented in Korea, European Union and Ukraine. The system of radiation protection in Korea is based on the Korean Atomic Energy Regulatory Enforcement on Safety Standards (Ministry Notice No. 2001-2). The notice is based on the recommendations in ICRP Publication 60 (1990) and IAEA Basic Safety Standards (1996). But the full implementation of the notice by the end of the year 2002 is not required because of the socio-economic situation and inexperience in internal radiation dosimetry Regulatory framework for internal radiation dosimetry is under development toward the full implementation of the notice from January 1, 2003. The system of radiation protection in Ukraine is based on the National radiation protection regulatory code NRBU-97. The code was developed and adopted in 1998 and replaced the Regulations of Former Soviet Union. The document is based on the ICRP Publication 60, Euratom Directive 96/29 and IAEA Basic Safety Standards (1996). The transitional period of 5 years (effected till January 2003) is established for implementation of all requirements of this new regulation. The system of radiation protection in the European Community is based on the Council Directive 96/29/Euratom, adopted in 1996 and enforced from 13 May 2000. Directive 96/29/Euratom has the status of the European law.
