Crassulacean acid metabolism (CAM) plants use surplus CO₂ generated by cooling and heating at night when ventilation is not needed in a greenhouse. Schlumbergera truncata 'Pink Dew' is a multi-flowering cactus that needs more phylloclades for high-quality production. This study examined photosynthetic characteristics by the phylloclade levels of S. truncata in a growth chamber and a greenhouse for use of night CO₂ enrichment. The CO₂ uptake rate of the S. truncata's top phylloclade in a growth chamber exhibited a C₃ pattern, and the second phylloclade exhibited a C₃-CAM pattern. The CO₂ uptake rate of the top phylloclade in a greenhouse showed a negative value both day and night, but those of the second phylloclade exhibited a CAM pattern. The stomatal conductance and water-use efficiency (WUE) of S. truncata at both the top and second phylloclades were higher in a growth chamber than in a greenhouse. The WUE of S. truncata in a growth chamber and a greenhouse was higher at the second phylloclade, which is a CAM pattern compared with those of the top phylloclade. The daily total net CO₂ uptake of S. truncata was higher in a growth chamber than in a greenhouse. The daily total net CO₂ uptake of S. truncata at the second phylloclade had the highest value of 155 mmol·m^-2·d^-1 in a growth chamber. The night total CO₂ uptake of S. truncate at the second phylloclade was 3-fold higher in a growth chamber than in a greenhouse. S. truncata's second phylloclade exhibited a CAM pattern that uptake CO₂ at night, and the second phylloclade, was more mature than the top phylloclade. A multi-flowering cactus S. truncata 'Pink Dew' efficiently uptake night surplus CO₂ in the proper environmental condition with matured phylloclade.

In order to analyze the experience of women from the provinces settling in Seoul, the current study conducts in-depth interviews on seven women who are working in Seoul after coming up to Seoul to attend and graduate from university. The results of the interview were analyzed using grounded theory methodology, under which the open coding extracted one hundred ten concepts, twenty-one sub-categories, and eleven categories encompassing them all. Causal condition is 'difficulty of settling in Seoul' and contextual conditions are 'intensification of psychological anxiety', 'reduction in quality of life', and 'continuation of economic instability'. The central phenomenon is 'dilemma of continuing life in Seoul' and intervening condition is 'diagnosis of ten years after coming up to Seoul'. Action/interaction strategies are 'changes in personal life', 'securing economic abilities through a stable job', and 'finding ways to participate in the society', while the result was 'choosing whether to continue living in Seoul'. The paradigm of experience of women from the provinces settling in Seoul proceed from coming up to Seoul for university to becoming independent, adapting to life in the city, experiencing growth and failures, facing challenge and searching for solutions, and conducting self-evaluation and making new choices. The participants reported that they were aware of differences and experienced anxieties as a stranger in Seoul even after living in the city for ten years; the problems they face have become more complex and diverse since when they were in university, and while they launched a career and making money, the gap between them and their peers from Seoul has not closed. The women also express desperation that they may need to leave Seoul to find alternatives to problems caused by accumulated stress and social problems that cannot be solved by an individual. In conclusion, the current study confirmed that efforts by individuals can only have limited effects in helping women from the provinces to settle in Seoul, indicating that detailed policy plans are required to solve social issues in the overall Korean society.

유명 요리사가 자신의 브랜드만을 빌려주는 식당과 직접 운영하는 식당이 있다. 에드워드 권에게 있어 QTV '에드워드 권의 예스셰프' (이하 '예스셰프 2', 지난 8월 20일 종영)는 말하자면 후자에 가깝다. 무작정 서울로 상경해 경양식집 주방 아르바이트생에서 버즈 알 아랍의 수석총괄주방장까지 이른 이 입지전적 요리사는 자신이 경험했던 치열한 주방의 경쟁 논리를 그대로 '예스셰프 2'에 적용한다. 이제는 시그니처가 된 '당신은, 자격이 없습니다'라는 차가운 탈락 멘트와 함께.

올해 노벨 생리의학상은 '내비게이션' 역할의 뇌세포를 발견한 3명의 신경과학자에게 돌아갔다. 영국 유니버시티 칼리지의 존 오키프 교수(John Okeefe)와 노르웨이과학기술대학(NUST)의 부부 과학자인 메이 브리트 모세르(May-Britt Moser), 에드바르드 모세르(Edvard Moser) 교수가 그들이다. 지금처럼 내비게이션이 보편화되기 이전, 초보운전자에게 가장 두려운 것은 차선 바꾸기나 주차하기가 아니라 바로 길 찾기였다. 모르는 길을 운전하는 것은 시골 샌님의 첫 서울 상경만큼 두려운 일이었다. 노벨위원회는 "사람들이 위치와 방향을 파악해 길을 찾을 수 있는 원리를 규명한 세 과학자의 공로를 높이 평가했다"고 선정 이유를 밝혔다.

This paper aims to compare meaning of the poetry called 'capital to coming to country' with the poetry called 'country not coming up to capital'. The poetry which have the garden and pastoral imagery is linked with the poetry called 'capital to coming to the country'. In contrary the poetry which have the farm imagery is linked with the poetry called' country not coming up to the capital'. The 'sajok' is the author of the nature poetry. To study the nature poertry in 17 and 18 centuries, it is necessary to the political, social and economical position of the 'sajok'.

The purpose of this study is to analyze the process of creative science problem solving (CSPS) in elementary school students. To do this, 6 graders (n=9) at a elementary school in Seoul were participated. In this study, fixed eye-tracker with 250 Hz sampling and observation camera were used. The results of this study, the students with higher ability to solve creative science problems had a slower saccade, and had more visual attention on core clues and a greater number of eye changes. Therefore, students with higher ability to solve creative science problems showed more effective eye movement and faster information processing to solve problems. The CSPS types of elementary students were classified as 'declarative knowledge type', 'procedural knowledge type', 'conditional knowledge type', 'knowledge lack type'. Because each type appears to be complementary, CSPS process for elementary students who have integrated the four types was devised. The results of this study can be used as basic data for understanding elementary school students' CSPS and will help to develop and guide creative science teaching and learning programs useful to elementary school students and science gifted students.
