At present, the trend in the direction of the world economy and industrial development is going with focus on creative industry. The British economist John Howkins, in his book ‘The Creative Economy’ published in 2001, said that the future industry would be dominated mainly by creative economy. In this light, we can easily figure out that creative economy and creative industry will play a greatly vital part in Korea`s entrance into the line of developed countries. Such a creative industry might be feasible on the basis of ingenuity; here, ‘Ingenious’ is closer to ‘Applicative’ rather than ‘Creative’. All the countries of the world are making much effort to improve creativity of students predicting that creativity can be improved through education. Hereupon, people often express an ingenious person as a convergence person in Korea. When it comes to mentioning a creative person in modern times, the founder of Apple, Steve Jobs is pointed out as the most representative figure, and Steve Jobs once said in his address in 1995 that ‘Creativity’ is not a task of making something out of nothing but a task of ‘bringing various experiences together.’ Thinking of this comment as a clue, it might be safe to say that creativity is premised on diverse experiences and knowledges. With the perception of its importance, the USA is implementing the STEM education platform, the convergence education constructed in 2007, and in Korea, keeping pace with this trend, STEAM education program (Science, Technology, Engineering, Art, Mathematics) which is established by adding humanistic part to STEM is being carried out. At present, the areas including Technology, Engineering and Arts are very insufficient qualitatively and quantitatively in STEAM platform which is being performed in Korea. Hereupon, this study intends to present an “Engineering Design -based Convergence Education Model for High School Students” with focus on these 3 areas and to present its difference with diverse examples investigated as well as its advancement direction. This study hopes this research work will contribute to engineering design-based high school student`s convergence education, secondary convergence education, and adult convergence education which are to be implemented later.

To deal with the future complex and diversified society, nurturing convergence-focused talents should be implemented based on accurate understanding on STEAM. We have to analyze and review relevant educational activities in a systematic way for more effective utilization.1) This study, based on the previous study in vol.16, aims at establishing evaluation items configuration for ``DOT LAB Program`` and objectified weighted value about its extracted standard index. To do so, this study uses collected evaluation data about importance and priority order with questionnaire, resulting in drawing output of weighted value configuration. As the result of the analysis, importance and priority order is placed in the order of ‘concept recognition’>‘contents composition’=‘convergence application’>‘creativity’. Specifically, 30 points for ‘concept recognition’, 25 points for ‘convergence application’ and ‘contents composition’ respectively, 20 points for ‘creativity’, marking total 100 points. In this study, when evaluating ‘DOT LAB Program``, it is significant to put more points to aimportant item rather than putting same points to all items, for specific differentiated evaluation.

The discovery of malignant cells in pleural fluid and/or parietal pleura indicates a disseminated or advanced disease in the patients with various malignancies. For 5-10% of patients with these malignant pleural effusions, the site of origin cannot be identified even though extensive work-up. Recently, 18F fluorodeoxyglucose positron emission tomography (FDG PET) has been shown to be a highly reliable and accurate test for detection and staging of lung cancer. We report here a case of histopathologically diagnosed metastatic bronchogenic adenocarcinoma of pleura without detection of primary lung cancer which was evaluated by PET, and review the diagnostic work-up and the role of PET in the malignant pleural effusion.
강변여과수 개발을 위한 낙동강 충적층 지하수의 지구화학적 특성연구

지하수의 인공함양특성을 해석하기 위한 기초조사로서 낙동강변의 충적층내에 부존하는 자연수의 지구화학적 특성을 연구하였다. 전체적으로 시추공 및 지표수에 대한 현장측정자료는 시기별로 큰 차이를 보이지 않는다. 연구지역의 자연수는 Ca-HCO3형에서부터 Ca-SO4형에 속하며 특히 미량원소로서 Mn의 함량이 매우 높게 나타나고 있다. 다중패커시스템 (Multi-packer system)에 의해 채취된 시료에 대해 심도에 따른 변화를 살펴보면 Na, Ca, Mg, HCO3의 함량이 심도가 깊어질수록 증가하고 있고, Cl과 SO4의 경우는 맨 하부구간인 18m에서 채취된 시료들이 시료채취시기와 관계없이 매우 낮은 값을 보인다. 미량원소의 경우 문제가 되는 Mn은 시료채취 시기와 관계없이 중간 구간인 13.5m 구간에서 특히 많은 함량을 보이고 있다. 연구지역내 물시료들에 대한 산소와 수소 동위원소 및 삼중수소 함량 분석결과는 다중패커설치공 및 일반 관측공과 지표수들간에 서로 중첩되어 구분이 어렵다. 황동위원소 분석결과는 지하수내 황의 기원이 퇴적암을 구성하는 황산염광물의 용해에 의한 것으로 판단된다. 스트론튬 동위원소비는 양수정 및 그 인접공의 시료들과 강변에서 인접한 공의 시료들간에 차이는 있으나 명확하지는 않다. 질소동위원소 분석결과를 살펴보면 전반적으로 화학비료로나 토양내의 유기물로부터 유래한 것으로 해석할 수 있다. Geochemical studies on the alluvial aquifer system near the Nakdong River were carried out for the basic investigation of the estimation of artificial recharge for the river bank filtration. In-situ data do not show any distinct difference between the pumping well and river. Most of waters belong to Ca-HCO3 and Ca-SO4 types and show high Mn concentration. In the borehole installed with Multi-packer (MP) system, Na, Ca, Mg, HCO3 contents of the groundwater are increased with depth increasing. Cl and SO4 contents of the groundwater show the lowest values at the bottom level (18m depth) and Mn content is very high at the middle level (13.5 m depth) of MP system. There is no distinct difference in the δ18O and D values and tritium content between MP, borehole and surface water samples. The sulfur isotope data indicate that the possible sulfur source is dissolution of sulfate mineral from sedimentary rock. Strontium isotope ratio shows a little differences between the pumping well and observation borehole samples. Nitrogen isotope data indicate that the nitrogen of water samples is originated from fertilizer or organic materials.
