To correspond to drastic change in international society such as "globalization", graduate education plays a key role in development of human resources. The new trans-graduate-school education program called "Nitobe School" was launched in 2015 as one of the main education projects of "Top Global University Project" in Hokkaido University. This is a trial case report of the comparison of commercial Transferable Skill test for the Graduate School students. We employed about 50 students from the various graduate schools in Hokkaido University, and they took same commercial Transferable Skill tests (Career Approach, PROG and SEQ), then its result was discussed in here.

For tuning education programs in the higher education, we should identify the status of courses (lectures) in education programs provided by target institutes such as graduate schools, or domestic and international universities relevant to target discipline. As a trial, we chose the courses relevant to environmental science in Hokkaido University, one of the 11 leading research universities in Japan. We extracted 240 syllabuses from 3,006 syllabuses of courses relevant to environmental science listed in an educational support system called ELMS, through the partial matching of "Kankyo", a Japanese word of environment, in their course titles or keywords in all syllabuses. We clarified that the courses relevant to environmental science are provided by many graduate schools such as the Graduate Schools of Engineering, Agriculture, Science as well as the Graduate School of Environmental Science. We also found some critical issues when we used ELMS as an Institutional Research (IR) tool, such as duplicate /triplicate syllabuses for the same course, and duplicately/triplicately named courses for "the same class" due to inconsistency of their syllabuses and no policy for their naming convention of courses.

To correspond to current trend in the international society which is rapidly adopting to the notion of "globalization", the graduate education plays a key role in development of human resources for the future. A new trans-graduate-school education program called "Nitobe School" was launched in 2015 as one of the main education projects of "Top Global University Project" at Hokkaido University, Japan. To foster the overall development of graduate students and to track their progress throughout the program, Nitobe School introduced a student e-portfolio called "NITOBE Portfolio". This portfolio is accessible to the registered students until their graduation. The student can freely interact with the instructors, discuss with fellow students, submit assignments on the e-portfolio and most importantly track individual progress during the course. This paper reports the impact of utilization of student e-portfolio in the program for evaluation, and discusses the system development assuming widespread use of such e-portfolio systems for research university in the future.

The new graduate school education program Nitobe School was launched in 2015 as one of main education projects of "Top Global University Project" in Hokkaido University. This new graduate program is aimed to supply currently undermined skill-set to students from different home graduate or professional school. The scope of the Nitobe School program is to foster students to be a global leader who might contribute not only for local societies but also internationally by Team-Based-Learning (TBL) and Project-Based-Learning (PBL) methods. Since students have different expertise including the area of STEM and humanity, teachers cannot guide classes with their field, rather teachers need to educate students using a general topics. This general education program apparently requires different approaches from the conventional one. After completion of the first year of Nitobe School, we took place the survey that asked students how they felt about our new teaching methods. Overall, students appreciated with the new methods that we carried out, but there are some spaces for further improvement. In this report, we suggest potential ways to improve the Nitobe School program, which will be able to enhance further educating students, and at the same time educate teachers toward the TBL and PBL.

The present university education system has been designed to make graduate students good problem solvers such that they can contribute to society through the skills acquired in the graduate schools. With focus on developing critical thinking and reasoning to solve local and global problems such programs have gained immense popularity among teachers and professors in schools and universities and termed as "Problem-Based-Learning"" (PBL). However, there has been very few programs that encourage students to become better Problem finders. This study is based on our own experience of teaching problem-finding as an important skill for a special graduate program in university education and our findings on its implication on students ability to comprehend real world problems.

This is a report the change of postgraduate student's English ability through the new trans-graduate-school education program "Nitobe School" in Hokkaido University. In the Nitobe School program, students need to take English placement test before and after the program. Students choose TOEIC or TOEFL as a placement test at the beginning and take same test after the program. Also they can know its result within one month after took a test. Therefore we conducted questioner survey of student's motivation against English study and analyzed the relationship between their motivation and the change of English ability through the program period.

A core (900 mm long) of the scleractinian coral Dipsastraea (Favia) speciosa was collected from Iki Island (approximate to 33 degrees 48N), Japan, one of the highest latitude coral reefs known to exist at present, where winter monthly mean sea surface temperature (SST) drops to 13 degrees C. The Sr/Ca profile was constructed using a bulk sampling method for the uppermost 280 mm interval of the core, which grew between 1966 and 2007, to test whether it could act as a suitable proxy for SST in a harsh environmental setting where reef-building coral do not usually survive. The Sr/Ca-SST relationship derived from the annual Sr/Ca and SST extremes predicted the observed monthly averaged summer SST extremes within an error range of 1.1 degrees C (1 s.d., n=40). The obtained Sr/Ca-SST calibration was also found to be valid for subtropical Dipsastraea (Favia) corals, proving its broad applicability. However, low-amplitude winter peaks were observed in the slow-growing intervals, which we confirmed (using individual spot analysis along a continuous growth line) result from the mixing of theca grown at different times. Our bulk sampling approach, across multiple growth lines in the skeleton of D. (F.) speciosa, led to the mixing of asynchronous skeletal part. At the study site, D. (F.) speciosa grows continuously, even during the cold season, suggesting that the skeletal Sr/Ca obtained from specimens of D. (F.) speciosa can be used as an SST proxy in the northwest Pacific marginal seas.

The physiological effects of high CO 2 concentrations, i.e., [CO 2], on plant stomatal responses may be of major importance in understanding the consequences of climate change, by causing increases in runoff through suppression of plant transpiration. Radiative forcing by high [CO 2] has been the main consideration in models of global change to the exclusion of plant physiological forcing, but this potentially underestimates the effects on the hydrological cycle, and the consequences for ecosystems. We tested the physiological responses of fossil plants from the Triassic-Jurassic boundary transition (Tr-J) succession of East Greenland. This interval marks a major high CO 2-driven environmental upheaval, with faunal mass extinctions and significant floral turnover. Our results show that both stomatal size (expressed in fossil material as SL, the length of the stomatal complex opening) and stomatal density (SD, the number of stomata per mm 2) decreased significantly during the Tr-J. We estimate, using a leaf gas-exchange model, that the decreases in SD and SL resulted in a 50%-60% drop in stomatal and canopy transpiration at the Tr-J. We also present new field evidence indicating simultaneous increases in runoff and erosion rates. We propose that the consequences of sto- matal responses to elevated [CO 2] may lead to locally increased runoff and erosion, and may link terrestrial and marine biodiversity loss via the hydrological cycle. © 2012 Geological Society of America.

Coral reefs are increasingly faced to the crisis of decline and death caused by climate changes and anthropogenic influence. These crises were reported in Shiraho coral reefs, the Ishigaki Island, Southwestern Japan, caused by the red soils runoff through the Todoroki River. In order to evaluate the influence of terrestrial inputs on coral skeletal growth and coral death, we have analyzed oxygen and carbon isotopic ratios, as well as Mn/Ca ratio, of coral <i>Porites</i>, skeleton collected from Shiraho reef. The coral colony used in this study was still alive but partly dead when the samples were recovered in 20th September 2006. Oxygen isotopic profile of necrosis part indicates that the death may have occurred in winter 2005 when a strongly positive peak of Mn/Ca ratio was observed in the same growth layer of living part, suggesting that increased terrestrial input during sugar cane harvest and closed water system during lower tide level in winter are a possible cause of coral necrosis in the Shiraho coral reefs.

世界で最も高緯度に位置する、日本の壱岐サンゴ礁より採取されたキクメイシ属サンゴ骨中の酸素・炭素同位体比を分析し、中緯度域における高時間分解能古気候アーカイブとしての可能性を検討した。まず試料は莢壁と軸柱の骨格構造別に分析し、その結果を生育時の環境記録と対比・検討を行った。この結果、軸柱と莢壁は形成のタイミングが異なっており、キクメイシ属サンゴの場合、莢壁の方がより正確に環境を記録することがわかった。また本研究で用いたサンゴ骨格は、骨格構造自体にも成長パターンの季節的変化が見られた。これらの成果を基に、さらに長期に渡る骨格分析を行い、これらを周辺の環境と対比・検討したのでその成果を報告する。

Reef-building corals are distributed in the tropical and sub-tropical oceans and can be found as fossils in a significant fraction of the geologic record extending back to the middle Triassic. Their skeletons continuously grow up to one of the largest biological architectures on the earth, which support various marine lives in nutrient poor regions. Moreover, recent global warming gives corals another importance as powerful tool to reconstruct paleoclimate recorded in their skeletons with high-resolution. Understanding mechanism of coral biomineralization is crucial and common subject among...
