  • The main question addressed in this research was whether an adaptation of a standard exercise Physiology Procedure would be sensitive enough to record excess oxygen uptake associated with speech activity. Oxygen consumption was recorded for a single subject during 7-minute rest periods and an automatic speech task, also 7-minutes long and performed at three different vocal efforts. The data show measurable and systematic speech-induced modifications of breathing and oxygen uptake patterns. The subject was found to use less power for normal than for soft and loud speech. This result is similar to findings reported by experimental biologists on the energetics of locomotion. However, more comprehensive feasibility studies need to be undertaken on a larger population before solid and detailed conclusions about speech energy costs are possible. However, it appears clear that, for experimental tasks like the present one, i.e., variations in vocal effort, standard exercise physiology methods may indeed offer a viable approach to recording excess oxygen uptake associated with speech movements.

  • Performance test is carried out in accordance with "performance test standard for Electrical Multiple Unit", noticed by Ministry of Construction & Transportation in 2000. The object of this standard is to ensure that vehicle is tested after completion and before entry into service. Performance test is classified by type test to be carried out for the first car and its components in order to verify their performance and by routine test to be carried out on the whole quantity in order to prove the performance of individual items. Scope of the test is divided by components, completed car, preliminary adjustment test and running test on main line. The paper introduces a testing procedure and an execution method of the performance test.

  • This paper deals with an automatic design standard computation based on a rated watt for a synchronous reluctance motor(SynRM). The focus of this paper is the design relative to the output power on the basis of rotor shape of a SynRM in each rated watt. The copuled Finite Elements Analysis(FEA) & Preisach model have been used to evaluate nonlinear solutions. The proposed procedure allows to define the rotor gemetric dimensions according to the rotor dia and rated watt starting from an existing motor or a preliminary design.

  • Emergency preparedness plan(EPP) is the systematic management of activities that involve a material degree of risk of loss or other damage to the surroundings(people, property and environment), and the boundary of accident recovery plan(ARP). The main purpose of the program is to provide a safety management system to each facility in order to enable to prevent accident and to control accident immediately. The EPP includes not only typical safety-related documentations such as material safety data sheet(MSDS), standard operation procedure(SOP), emergency response plan(ERP). EPP is established basis of the preliminary safety analysis involving risk identification, assessment and prevention plans. The program is also helpful for government or related agencies to control a number of accidents in small-scale companies in the whole country.

  • Environmental issues have become gradually important around the globe, which has increased society needs for the environment-friendly construction. In an effort to realize the environmental protection and energy efficiency, the British BREEAM has been developed, which is followed by the USA LEED, Japanese CASBEE and other national certification systems based on their own conditions. In this end, the Republic of Korea has implemented its own certification system named GBCS(Green Building Certification System) in 2002, and now actively promoted the G-SEED(Green Standard for Energy and Environmental Design) after GBCS modifications and amendments. The purpose of this study is to identify possible problems to be encountered in the process of the G-SEED for office facilities and to provide relevant solutions. In this end, three office facilities have been selected, which had obtained the G-SEED. This study has analyzed reasons of change of assessment scores between the preliminary certification and the main certification phases, has identified problems through in-depth interviews with practicing professionals(design, construction, eco-friendly consulting firm) and then has reached a conclusion for improvements. This study will be possibly used as reference materials for improvements of the green building certification system, and further detailed studies on respective parts will be required for improvements.

  • 1992년 리우 환경개발회의에서 채택된 Agenda 21에서 방사성폐기물의 안전관리를 위한 정책방향이 결정된 후, 국제연합은 방사성폐기물 안전관리를 지속 가능한 발전의 범위에 포함하여 국제원자력기구의 주관 하에 관련 지표의 개발 및 적용을 추진하고 있다. 2002년 국제원자력기구는 방사성폐기물관리에 관한 지속가능 발전지표를 확정하고 현재 운영중인 방사성폐기물 데이터베이스 시스템인 NEWMDB와 연계하여 회원국의 방사성폐기물관리 체계 및 현황을 정량적인 지표로 평가할 예정이다. 본 논문에서는 방사성폐기물에 관한 지속가능 발전지표의 도입근거와 적용상의 한계점을 분석하고, 국제원자력기구가 제시한 지표의 평가방법과 표준화된 절차를 도식화하였다. 도출된 평가절차에 따라 우리나라를 포함한 주요 국가의 방사성폐기물관리 체계 및 현황자료를 이용하여 각 국의 방사성폐기물관리에 관한 지속가능 발전지표를 평가하고 그 결과를 비교 분석하였다. 또한 지표의 향상을 통해 국내 방사성폐기물관리의 지속 가능성을 제고할 수 있는 방안을 도출하였다.

  • 본 연구는 강원도 지역의 토양환경을 평가하기 위하여 측정망 167개 지점의 토양시료를 분석하여 pH와 중금속에 관한 오염도 조사를 수행하였다. 전체 토양의 pH의 범위는 4.3~8.4로 나타났으며, 중금속의 경우 Cd 0.089 mg/kg (0.000~3.493 mg/kg), Cu 3.093 mg/kg (0.078~60.263 mg/kg), Pb 4.74 mg/kg (0.010~38.080 mg/kg), Hg 0.054 mg/kg (0.002~1.050 mg/kg), As 0.971 mg/kg (0.031~77.051 mg/kg)으로 나타나으며,$Cr^{6+}$은 검출되지 않았다. 중금속 오염에 의한 토양의 상태를 종합적으로 판단할 때 토양의 우려기준에 크게 못 미침으로 강원도의 토양은 비교적 청정한 것으로 나타났다.

  • Official nursing education of Korea under Japanese rule began in order to make the communication possible among Japanese medical men and Korean patients. It could generate high standard nurses from the beginning. Nurses licensure began in 1914 and the graduates of official nursing schools could get nurses licensure without further test. Official nursing education became the standard of R.N. education. The curriculum emphasized on Japanese and ethics first, and in order to produce nurse, practice second. In 1920 the shortage of nurse became serious problem, so the Japanese colonial authorities set up 5 official nursing school in large scale. In 1922 they revised the relevant laws and regulations to make the nursing licensure pass all over Japanese ruling area. 8-year preliminary education and 2 year curriculum became standard of official nursing education after then. Other nursing schools should satisfy this standard to let their graduate get nurses licensure without further test. Curriculum was revised to satisfy the dual goal of 'good housewife' and 'good nurse'. Every official nursing school tried to raise educational standard Nursing science was specialized and more emphasis was put on the occupational education. From the late 1930s, Japanese desperately needed additional manpower to replenish the dwindling ranks of their military and labor forces. They tried to produce more nurses by increase nursing school. Students had to do wartime work instead of study. Younger students could enter nursing school, and general school could produce R.N. In conclusion, nursing education of Korea under Japanese rule was determined by the official nursing education. The Japanese colonial authorities lead the official nursing education. It made nursing education fixed early and produced high standard R.N. But it made nursing education withdraw in late Japanese rule period. Nursing education of Korea began quite weak in the need of nursing and Korea herself. The weakness became a subject of nursing education of Korea after Japanese rule to produce better R.N..

  • 2018년 발사를 목표로 한국항공우주연구원이 개발중인 정지궤도복합위성(GEO-KOMPSAT-2)은 사용되는 발사체에 따라 GTO(Geostationary Transfer Orbit) 혹은 SSTO(Supersynchronous Transfer Orbit)를 거쳐 정지궤도에 진입하게 된다. GTO는 오늘날 대부분의 정지궤도위성이 사용하는 방식인 반면 SSTO의 경우는 사례가 많지 않고 GTO와는 완전히 다른 기술적인 접근이 필요하다. 본 논문에서는 정지궤도복합위성에의 적용을 목표로 SSTO 운용의 제약 사항을 정리하고 SSTO로부터 정지궤도로 진입하기 위한 액체원지점엔진 점화계획을 예비적인 수준에서 구성하였다. 또한 지상추적소의 가시성을 포함한 궤도 시뮬레이션을 수행하여 구성된 계획을 검증하였다.
