  • 일본 도야코에서 2008년 7월 열린 G8 정상회의에서 2050년까지 전세계 온실가스 배출량을 절반으로 줄이는 장기 목표를 추진하는 방안이 논의되었다. 우리나라도 2013년부터 기후협약 규제가 거의 확실시되고 있다. 화석연료의 연소로 대부분의 전력을 생산하는 발전산업은 우리나라 $CO_2$ 대기배출량의 20[%] 이상을 차지하고 있다. 발전소의 화석연료의 소모와 이에 따른 $CO_2$ 대기배출 규제는 갈수록 엄격해 질 전망이며 전력생산단가에 크게 영향을 끼칠 것이다. 본 논문은 발전소의 연료교체 검토 시 $CO_2$ 배출비용을 감안하는 간단한 경제성 검토를 수행하였다. 중유전소 발전소인 D 발전소가 LNG로 연료전환을 고려할 경우, 발전비용이 같아지는 ton당 $CO_2$ 배출비용, 즉, LNG-중유 연료교체의 손익분기점에 해당하는 ton당 $CO_2$ 배출비용을 계산하는 방법과 예제를 제시하였다. 이를 위하여 D 발전소의 성능시험 결과 얻어진 입출력 특성계수를 이용하였다.

  • The Korea UK e-Science Collaboration project has been aimed at supporting research and collaboration between Korean and UK researchers. Its goal is to benefit the nation by reducing cost and time in constructing the National e-Science Research Environment' by studying and benchmarking the cases in countries that have already procured advanced technologies in the area. Two joint workshops were held in a year where researchers from the two countries had the opportunities to share their research results with each other. Also, the project has supported exchanges of researchers fostering expertise in the field. In the course of the project, the e-Science Centre in the UK and KISTI have signed MoU(Memorandum of Understanding) in 2006. Moreover, there have been active research collaboration between Korea and the UK. The University of Southampton will share the BioSimGrid data with the Korean counterpart, and the University of York has provided the AURA software. In the future, KISTI and the UK NGS(National Grid Service) will organize a working group at OGF that will work mainly on the standardization of Parameter Sweep and bring it to lead the global standard. KISTI will include its own AURORA system into OMI-UK software stack, which will enable access to NGS resources through AURORA user application. The collaboration with the UK has opened up more opportunities for collaboration with other countries as well. KISTI and HLRS in Germany have agreed to share the COVISE and will have research exchanges. As such, it is expected that Korea will play a major role in e-Science research by building strategic and systematic collaborative relations with its International partners.

  • We examined the effects of the vibration stress on cortisol secretion and hematological characteristics in soft-shelled turtle, Pelodiscus sinensis. For the stressed group vibration of $45{\sim}78 dB(V)$ from electric vibrator applied for 30 min with 2-h intervals during daytime ($08:00{\sim}18:00$) up to 28 days. Using the blood samples collected from ten turtles held once a week after vibration stress, we measured hematocrit, hemoglobin, red blood cells, cortisol, glucose, lactic acid, osmolality, $Na^+,\;K^+,\;Cl^-$, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). The results have showed that P. sinensis received vibration stress exhibit the 'typical' stress-induced physiological responses (cortisol, glucose, lactic acid, osmolality, ions, hematocrit and hemoglobin) induced by vibration stress. Our data suggested that chronic vibration stress caused substantial stress in the animal, and in particular, the persisting elevated levels of AST and ALT would be highly correlated with the adverse effects of the stress. The high hematological characteristics during entire experimental period showed that the P. sinensis could not adapt to chronic stimuli provoked by vibration stress.

  • Community facilities in most rural villages have many problems in the aspect of their size or functions as well as they are generally too superannuated to support diverse community activities; which results in a low degree of inhabitants' satisfaction with community facilities, and inconvenience for using them. Therefore, it may carefully be said that it's time to need the established studies that are necessary with consider to community facilities which can reflect inhabitants' diverse activities. In this study, 5 places which the most common events among the major monthly events of total 25 rural villages were held were selected as the subject place for survey; and then investigated, by means of the participant observation method, the using behavior of inhabitants who used community facilities. Focusing on size, factors, and layout that were being faced by community facilities in most rural villages, This study investigated the number of users, the characteristics of traffic line and behavior, and the using behavior by group; through considering their correlation with the physical setting of community space, it deduced the problems of use; and it proposed the direction of improvement on the basis thereof. Therefore, this study will serve in the future as useful basic materials for designing a rural village's community facilities in consideration of size, factors and layout which can appropriately support inhabitants' community activities.

  • Purpose : The aim of this study is to review the current status of healthcare provision and its human resources administrative management and propose a coordinated human resource management plan for the more efficient operations of healthcare organizations. Methods : We reviewed the literature and held discussions with officials from the United States Department of Health and Human Services to survey United States Public Health Service Commissioned Corps operations. In addition, we surveyed the literature to analyze the current structure and responsibilities of governing bodies involved in public healthcare in Korea. Results : In Korea, there are several administrative offices involved in public health: the Ministry of Health and Welfare, the Ministry of Defense, the Environment Ministry and others. Since these diverse agencies don't integrate their operations, it is difficult to grasp their management of both public healthcare services and their personnel. A potential model is the United States Public Health Service Commissioned Corps, a sub-group of the Department of Health and Human Services and an elite team of highly qualified, public health professionals, which coordinates and manages the overall work and personnel of diverse healthcare organizations. Conclusion : We suggest the establishment of a federal level, public health administrative department of human resource management to centralize and coordinate the existing, disparate healthcare administrative agencies.

  • This study held physical measurement for male subjects in their 20s living in Ningbo City, Zhejiang Province in China, showing the biggest market in men's clothes. Their representative lower body types with average shapes and sizes were chosen so as to develop men's slacks patterns with better dimension fitness. The following are the results of the analysis: 1. Slacks patterns were made based on the mean measurement values of 5 people, who were closest to the representative body types, from the index*absolute group of 47 people. The dimensions of application for slacks pattern-making were 77cm(omphalion waist circumference), 91cm(hip circumference), and 103cm(slacks length). 2. For the comparison of high-fitness and more-room pattern dimensions, 5 styles of slacks were made: Korean, Chinese, British, Japanese, and industrial. In the dressing fitness tests, industrial patterns had excellent appearance and Japanese ones had the best function. 3. Based on the analysis results of slacks pattern comparison, the target slacks were experimentally made and received superior evaluation points to the compared slacks patterns in two times of evaluation for appearance and function. 4. The final slacks pattern in this research had the following dimensions: front waist circumference: W(1-2cm with room included)/4-1cm, back waist circumference: W/4+1cm, front hip circumference: H(9$\sim$10cm with room included)/4-1cm, back hip circumference: H/4+1cm, crotch length: H/4-1.5cm, hip length: crotch length-H/12, front crotch extension: H/16-1.5cm, back crotch extension: H/8+3cm, knee line: 33cm below crotch line, front tuck amount: 4cm, back dart amount: 2.5cm(center) and 1.5cm(side), and back dart length: 10cm (center) and 6cm(side).
