Employing female in the field of science and engineering is becoming increasingly important with diversity and creativity emerging as key factors to build Creative Economy. Under these circumstances, it is necessary to recognize and discourage gender discrimination in the labor market by analyzing wages - the market value of labor which determines one's economic status. This study uses the Oaxaca-Ransom decomposition (1994) to analyze the gender wage gap and identify factors influencing the pay gap in science and engineering labor force. The results of this study are as follows: First, the average wage of female scientists and engineers reaches only 65% of that of male labor force, and the male scientist and engineers are superior in terms of personal attributes, for instance, education background. Second, looking at the factors that influence wages, wage premiums are associated with higher education background, older age, longer period of service, and weekly working hours for both male and female in managerial positions. Third, the wage decomposition shows that in the case of science and engineering labor force, the productivity difference by personal attributes reaches about 58%, and gender discrimination by the characteristics of the labor market stands at about 41%. This means the wage gap by productivity level in science and engineering labor force is wider, and the gender gap is smaller compared to non-science and engineering fields. However, the results of an analysis on specialties and education background of male and female scientists and engineers suggest that the discrimination against women is more serious when the percentage of the female labor force is low and the percentage of temporary workers in the labor market is high. In order to eliminate this discrimination, it is necessary to reduce the imbalance of female scientists and engineers in the labor market, among others, while female scientists and engineers, themselves, need to make continuous efforts to strengthen their capabilities.

The purpose of this study was to investigate secondary science teachers' general perceptions of scientific and creative problem solving. The secondary science teachers responded to a survey. The results indicated that most of the teachers perceived enhancing scientific and creative problem solving skills as one of the most important goals in teaching science. However, they hardly implemented instructions for scientific and creative problem solving in their science lessons. They reported the absence of specialized teaching strategies and assessment tools for scientific and creative problem solving, and university entrance exam-oriented social and educational atmosphere as major barriers. In addition, the teachers tended to present limited understanding of scientific and creative problem solving, which is merely focused on creativity. Considering the results, it was thought that a guide to a clear conception of scientific and creative problem solving was needed. Also, many teaching strategies and appropriate assessment tools for adopting and scientific and creative problem solving were required.

In the forensic microbiology laboratories, microorganism analyses from food are requested. There have been several cases of Bacillus cereus isolated from the samples requested to the National Forensic Service. B. cereus is an important pathogenic bacterium which can cause food-borne outbreaks. Therefore, we isolated B. cereus from anchovy aekjeot recently requested for microbial examination and identified using MSId based on the 16S rDNA sequence and real-time PCR method. We also conducted PCR for detection of diarrheal toxin genes and an emetic toxin gene and found the presence of nheABC, bceT and entFM diarrheal toxin genes in the B. cereus isolate. There are several clinically important food-poisoning bacteria that should be noted during inspection. In particular, B. cereus can cause food poisoning even when cooked foods are ingested, because B. cereus forms endo-spore which confers strong environmental resistance and heat resistance to the bacteria, and the bacterial emetic toxin also has heat resistance. Here we highlight the importance to distinguish clinically important bacteria such as B. cereus from food specimens, and we expect this study will provide procedures for identification of B. cereus and detection of the bacterial toxin genes for future cases in the forensic microbiology laboratories.

기후변화에 따른 강우특성의 변화는 다양한 기상이변과 극한사상의 발현으로 사회적 관심이 높아지고 있는 이슈이다. 일반적인 기후변화 연구는 전지구 기후 모델 (GCM, General Circulation Model) 산출물에 기반하여 생산된 미래 기상정보를 바탕으로 이루어진다. 최근 국내 연구에서 주로 활용되는 자료는 IPCC 5차보고서(AR5)의 과학적 기반자료로 활용되는 CMIP5(Coupled Model Intercomparison Project, phase 5) GCM 산출물이다. 수자원, 농업, 경제의 다양한 분야에서 기후변화 영향평가가 심층적으로 이루어지고 있는 가운데 미래기간에 대한 GCM 산출물에 대한 신뢰성에 대한 평가 연구는 상대적으로 미흡한 실정이다. 모델의 신뢰성은 산출물의 실제 현상에 대한 재현성을 평가함으로서 가늠할 수 있다. 본 연구에서는 한반도 지역에 대한 전지구 모델의 성능을 평가하기 위해 동아시아 지역의 격자단위 관측자료를 수집하여 과거기간(1970~2005)에 대한 강우특성 공간분포를 분석하고 이에 대한 GCM 산출물의 재현성을 평가하였다. 위도와 경도에 따른 강우특성의 공간적 변동성에 대한 GCM 결과의 상관성과 평균/절대오차를 산정하여 29개 CMIP5 GCM의 순위를 결정하여 제시하였다. 이 분석은 동아시아 해안지역과 한반도 지역을 구분하고 다양한 강우특성에 대한 재현성을 통합적으로 고려하여 이루어졌다. 연구 결과 오차 통계와 대상지역에 따라 GCM 순위가 상이하게 나타났으며 특히 공간분포의 패턴과 절대적 오차를 기준으로 판단한 GCM 순위가 크게 다르게 나타났다. 대체로 Hadley Centre 계열 모델의 동아시아 지역에 대한 강우특성 재현성이 높게 나타났으며 한반도 지역만을 대상으로 평가했을 때 MPI_ESM_MR과 CMCC center 계열 모델의 재현성이 높게 나타났다. 본 연구결과는 향후 한반도 지역의 기후변화 영향평가에 가중있게 고려되어야 할 GCM의 선정과 GCM 성능고려에 따른 기후변화 예측 불확실성 평가에 적용될 수 있으며 다양한 영향평가 연구결과의 신뢰도 제고에 기여할 것으로 기대된다.

The membrane-based CO2 capture is a fast-growing branch in gas separating field. Ionic liquid assisted mixed matrix membrane (MMM), which consists of organic fillers with dispersed ionic liquid, shows high potentiality as a candidate for CO2 separation medium. In MMM, various kinds of ionic liquid and inorganic filler are incorporated into polymer to enhance gas separating performance. Especially, the strong interaction between ionic liquid and organic filler gives huge influence on enhancing the separating performance by increasing affinity, selectivity and adsorption of CO2 into the framework. Also the mechanical properties of metal organic framework are positively tuned by input of ionic liquid to improve CO2 permeability and selectivity. In this review, study of various combinations of ionic liquid and metal organic framework (MOF) in the polymeric membrane for carbon dioxide separation is discussed.

The purpose of this study was to investigate preservice elementary school teachers' views on the relationship between science/technology and society. Freshmen (n=93) and seniors (n=82) at three universities of education were asked to express their views with 8 items in the Views On Science-Technology-Society, which consisted of two subcategories; 'influence of science/technology on society' (4 items) and 'influence of society on science/technology' (4 items). Mann-Whitney U test revealed that the scores of the freshmen were higher than those of the seniors. This trend was notable particularly in the item concerning 'influence of corporations on science/technology' and 'influence of interest groups on science/technology'. In comparing the scores by gender, a significant difference was found in the item concerning 'influence of policy on science/technology' for the freshmen.

This study investigates the future world of The Perfect Society (1967), science fiction written by Yunsung Moon that was a very rare science fiction publication in the 1960s. In The Perfect society, the main character Woo Sungoo, who was chosen to survive in a sleeping capsule as a representative of $20^{th}-century$ human beings, wakes in the $22^{nd}$ century where only women remain. He experiences this female utopia and finds that this world still contains as much abnormal antipathy to the others and absolute autocracy as the 20th-century world he remembers even though the future people succeed in overcoming the past problems like famine and pollution. The author warns that science alone without humanistic insight in a unity-oriented society cannot settle the human's fate; rather, it only changes the aspects of human conflict.
