Background/Aims Functional dyspepsia (FD) is one of the commonest diseases in the field of Internal Medicine. The Japanese Society of Gastroenterology (JSGE) has been enlightening the term and concept of FD. Aim of this survey was to elucidate the understanding status of FD and Rome criteria and attitude toward FD among Japanese internists. Methods Data were collected at the time of lifelong education course for certified members of Japanese Society of Internal Medicine. Self-administered questionnaires were delivered to the medical doctors prior to the lectures. Results Analysis subjects were 1,623 (24-90 years old) internists among 1,660 medical doctors out of 4,264 attendees. The terms related to FD were known in 62.0-68.9% of internists, whereas 95.5% understood chronic gastritis. Internists who had been taking care of FD patients informed them as chronic gastritis (50.0%), FD in Japanese Kanji character (50.8%) and FD in Kanji and Katakana (18.6%). Logistic linear regression analysis revealed that positive factors for the understanding of FD and intensive care for FD patients were practitioner, caring many patients and certified physician by JSGE. Existence of Rome criteria was known in 39.9% of internists, and 31.8% out of them put it to practical use. The certified physician by JSGE was a positive factor for awareness, but not for utilization. Conclusions The results suggest the needs of enlightening the medical term FD in Japan and revision of Rome criteria for routine clinical practice. Precise recognition of FD may enhance efficient patient-based clinical practice. (J Neurogastroenterol Motil 2014;20:94-103)

The challenge of predicting the Japanese coastal ocean motivated Frontier Observational Research System for Global Change (FORSGC) and the Japan Marine Science and Technology Center (JAMSTEC) to start a multiyear observational programme in the upstream Kuroshio in November 2000. This field effort, the Kuroshio Observation Program (KOP), should enable us to determine the barotropic and baroclinic components of the western boundary current system, thus, to better understand interactions of the currents with mesoscale eddies, the Kuroshio instabilities, and path bimodality. We, then, will be able to improve modeling predictability of the mesoscale, seasonal, and inter-annual processes in the midstream Kuroshio near the Japanese main islands by using this knowledge. The KOP is focused on an enhanced regional coverage of the sea surface height variability and the baroclinic structure of the mainstream Kuroshio in the East China Sea, the Ryukyu Current east of the Ryukyu's, and the Kuroshio recirculation. An attractive approach of the KOP is a development of a new data acquisition system via acoustic telemetry of the observational data. The monitoring system will provide observations for assimilation into extensive numerical models of the ocean circulation, targeting the real-time monitoring of the Japanese coastal waters.

The gastric barostat study is the gold standard method for evaluating gastric perception and accommodation. This technique has serious drawbacks, such as expense and invasiveness. Several drinking tests have been developed as noninvasive methods. Such tests are easily performed without special instruments and are well tolerated. We have reported that (1) a threshold volume inducing mild bloating in the slow nutrient drinking test might be an alternative parameter of gastric accommodation volume as determined by the barostat method and (2) the maximum satiety volume in the drinking test correlated positively with the pressure to induce severe discomfort in healthy volunteers, indicating that the slow nutrient drinking test may be useful for evaluating accommodation volume and the threshold to induce severe discomfort. However, the correlation between the maximum satiety drinking volume and accommodation volume as measured by the barostat study has been controversial. Therefore, validation of a certain nutrient drink test for measuring gastroduodenal function might be recommended in each institution. (J Neurogastroenterol Motil 2012;18:332-335)

The objectives of this study were to distinguish fossil specimens of Meretrix (Bivalvia, Veneridae) using discriminant score and multivariate analysis, and to examine temporal changes in the geographical distributions of M. lusoria and M. petechialis in Japan and South Korea. Fossil shells of Meretrix were collected from Miyagi, Fukui, Aichi and Kumamoto in Japan, and Gimhae, Seosan, Siheung and Ganghwa-do in South Korea. The outside of the right valve was photographed with a digital camera, and ten characteristics of the shell morphology, such as shell height and shell length, were measured using image analysis software and a digital slide caliper. The discriminant score and multivariate analysis of the shell morphology identified all of the examined fossils as M. lusoria, while living individuals collected from the western coast of South Korea were identified as M. petechialis. These results suggest that the fossil shells excavated from the western coast of South Korea are a different species from the living individuals collected from the same areas. Radioactive carbon isotopic results revealed that the ages of the four fossil shells collected from tidal flats in Ganghwa-do ranged between 3,270 ± 30 and 1,830 ± 30 Cal BP. These results suggest that M. lusoria inhabited the western coast of South Korea until at least 2,000 years ago, but was replaced by M. petechialis during the last 2,000 years. Therefore, we propose that either M. petechialis spats were introduced artificially, or planktonic larvae migrated naturally from China to the western coast of South Korea during the last 2,000 years.

In order to re-examine the taxonomic position of the Korean striped field mouse, Apodemus agrarius chejuensis from the Cheju Island, external value and skull characters were compared among A. agratius coreae from the Korean Peninsula, A. speciosus, A. argenteus, and A. semotus. Skull characters of A. agratius chejuensis (Cheju population) and A. agrarius coreae (mainland population) were fitted onto different clines. In particular, distances between the posterior and of incisive foramina and anterior end of the first upper molar were critically different between these two subspecies. These evidences support the specific division of 'Apodemus chejuensis' for the population inhabiting the Cheju Island from A. agratius in the mainland, as proposed by Koh and Yoo(1992).
