  • Now we are facing severe environmental issues such as global warming. Due to these, the concerns about eco-friendly energy have been increased. Kyoto protocol and Copenhagen climate change conference are circumstantial evidence of it. With these trends, the interests for the Electric Vehicles(EVs) which do not emit any harmful gases have gradually been raised. Unfortunately, however, massive connection of EVs to the power system could cause negative impacts such as voltage variations, frequency variations and increase of demand power. To prevent the mentioned issues, KEPCO adopts Time-of-Use(ToU) price for EVs charging. Nevertheless, it is important to verify the propriety of the charging system. In this paper, therefore, we used pre-introduced price elasticity concept to predict possible Demand Response(DR) on charging of EVs. And analyzed possible demand power increase according to various price elasticities. Simulation results show that given ToU based charging system would not enough to control the increase of demand power by EVs on the power system. It is concluded, therefore, additional methods and/or algorithms are required.

  • The cdd gene of Bacillus subtilis, encoding the deoxycytidinecytidine deaminase of pyrimidine nucleotide biosynthesis has been cloned into the EcoRl site of pBR322. The recombinant plasmid, pSol, promoted the synthesis of 100-140 fold elevated levels of the enzyme. A comparison of the polypeptides encoded by cdd complementing and non-complementing plasmids in the mini cell showed the gene product to have a molecular mass of approximately 14 kDa. The nucleotide sequence of the gene and 460 base pairs upstream from the coding region was determined. An open-reading frame, encoding a protein with a calculated molecular mass of 14337 Da, was deduced to be the coding region for cdd. However, the enzyme has an apparent molecular mass of 54 kDa as determined by gel filteration, whereas sucrose density gradient centrifugation shows 58 kDa. It means that the enzyme could be forming a tetramer in a physiological state. About 28 amino acids of the N-tetramer in a physiological state. About 28 amino acids of the N-terminal presumably form a signal for membrane translocation and six cystein residues are contained in the structure. S1 nuclease mapping indicated that transcription of cdd is initiated 17 base pairs upstream from the translational start. The structural characterization of the odd gene was performed.

  • The purpose of this study is to come up with ways that cooperate between on-line game design and fashion design by analyzing trend color and on-line game character's costume color in on-line game. As for the research methodology, First, on-line games were selected with reference to www.ranky.com. Second, 2009 SS trend color palettes suggested by Copenhagen International Fashion Fair was used as a criterion of fashion trend. Third, on-line game character's costume colors were analyzed in relation to the degree of reflection of trend and the game character's type. The results are as follows. Each on-line game character costume's colors were made in accordance with typical character types. But we can find a one-to-one correspondence between fashion trend colors and game character costume's colors. That's because both trends and character types are the results of the continuing interactions between human-beings and societies. In comparison with fashion trend colors, game character costume colors are partly raw and inharmonious. Therefore, it is necessary to apply fashion trend color in game character costume design for enhancing competitiveness in the world market.

  • This study provides the first systematic literature review of cervical cancer incidence and mortality as well as human papillomavirus (HPV) genotype prevalence among women with cervical cancer in the Pacific Island countries and territories. The cervical cancer burden in the Pacific Region is substantial, with age standardized incidence rates ranging from 8.2 to 50.7 and age standardized mortality rate from 2.7 to 23.9 per 100,000 women per year. The HPV genotype distribution suggests that 70-80% of these cancers could be preventable by the currently available bi- or quadrivalent HPV vaccines. There are only few comprehensive studies examining the epidemiology of cervical cancer in this region and no published data have hitherto described the current cervical cancer prevention initiatives in this region.

  • If we look closely to the power shift of the powerful countries historically. during the 16th century Spain's power came from gold, colony trade, the mercenary force, close relation with the thrown, 17th century Netherlands owes their power to trade, capital market, the marines, 18th century France owes it to population, agriculture, public administration, and the army. Also, England had their industry, political unity, finance and trust, the marines, liberalistic principles, a geographical merit of being an island which can be defended well and the 20th century America has their cosmopolitan culture, supernational communication, the capacity of the economy, science technology, military strength, alliances, liberalism international formation. But in the 21st century culture and art will prevail over the information age where technology and knowledge was the key, and it is predicted that this will be the source of power for a strong country. Rolfe Yesson, the head of The Copenhagen Research Center for future studies said, "Information age has ended and in the future Dream Society will arrive which focuses on making distinctions by delivering dreams and emotions to consumers". As cyberspace gradually substitutes reality, cyberspace has become more than an information search engine and has become a place where people fulfill their desires and exchange culture. And as a medium for diffusing culture, the importance of the digital dress-up avatar is predicted to increase gradually.gradually.

  • 지구 기후 변화 정책에 대한 논쟁의 대부분은 그들의 정치적 호소에 대한 초점을 맞추고 있지만, 이 논문은 계약의 약속이 보다 효율적임을 제기한다. 이 목표에 부합하는 기후 정책은 상당한 배출 감축을 목표로 한다. 이러한 시나리오가 지구 평균 기온의 증가를 제한한다. 21세기 중반까지 2010에 비해 40~70%에 의해 세계 온실 가스 배출량을 낮추겠다는 의미이며, 대기로부터 이산화탄소를 제거할 수 있다는 결론에 이른다. 이 논문은 환경과 개발(UNCED)에 관한 유엔 회의 자료를 분석하여 이러한 비교를 제공한다. 분석내용은 결론적으로 각 나라들이 협정에서 제시한대로 배출오염 물질을 줄이는데 이행하고 지구 온난화의 지속적인 발전방안이 요구되는 협력체계가 중요하다는 것을 확인하였다.

  • Purpose: Few studies have considered the psychosocial work environment factors in relation to employee health. This study explored the relationship between psychosocial work characteristics and self-rated health among Korean employees. Methods: The study population of 21,476 employees was derived from the 2014 Korean Work Environment Survey (KWES). Psychosocial work environment was measured by Copenhagen psychosocial questionnaire scales. Results: Among employees at workplaces (n=21,476), 23.3% rated their health as poor. Among 12 indicators of psychosocial work environment characteristics, 'higher emotional demand', 'demands for hiding emotions', 'work-family conflict', and 'social community at work' were independently associated with risk of poor self-rated health of Korean employees after adjustment of all sociodemographics, work condition characteristics and physical work environment exposure. In addition, higher 'possibilities for development' and 'social support from supervisor' were more likely to decrease the risk of poor health. Conclusion: We suggest that psychosocial work environment is an important determinant of employees' health. The study results provide a good starting point for developing intervention and strategies for health improvement.

  • The paper introduces the research area of interactive information retrieval (IIR) from a historical point of view. Further, the focus here is on evaluation, because much research in IR deals with IR evaluation methodology due to the core research interest in IR performance, system interaction and satisfaction with retrieved information. In order to position IIR evaluation, the Cranfield model and the series of tests that led to the Cranfield model are outlined. Three iconic user-oriented studies and projects that all have contributed to how IIR is perceived and understood today are presented: The MEDLARS test, the Book House fiction retrieval system, and the OKAPI project. On this basis the call for alternative IIR evaluation approaches motivated by the three revolutions (the cognitive, the relevance, and the interactive revolutions) put forward by Robertson & Hancock-Beaulieu (1992) is presented. As a response to this call the 'IIR evaluation model' by Borlund (e.g., 2003a) is introduced. The objective of the IIR evaluation model is to facilitate IIR evaluation as close as possible to actual information searching and IR processes, though still in a relatively controlled evaluation environment, in which the test instrument of a simulated work task situation plays a central part.

  • Purpose: This study aims to determine the association between psychosocial work environment and self-rated health among general hospital nurses. Methods: A total of 195 nurses working in one general hospital were eligible for data analysis by multivariate logistic regression. The psychosocial work environment was measured with the Korean version of the Copenhagen Psycosocial Questionnaire version II (COPSOQ-K). Self-rated health was recoded as good (excellent/good) and not good (fair/poor/bad) to the question, "In general, how would you rate your health status?" Results: 40% of nurses rated their health positively. Commitment to the workplace (OR=1.27), predictability (OR=1.32), recognition and reward (OR=1.41), role clarity (OR=1.32), and social support from colleagues (OR=1.25) were positively associated with self-rated health of nurse participants. Work-family conflict (OR=0.82) was negatively associated with self-rated health. Conclusion: The findings suggest that psychological work environment predicts self-rated health of hospital nurses. Good psychological work environment may be helpful in improvement of nurses' health.
