Asia-Pacific nations' declining birth rate and growing proportion of elderly people will lead to more importance in higher educations for the coming ages where low efficient jobs will be replaced by new technologies and students must work even harder to acquire valued-skills esteemed by societies. This paper proposes a stimulation method for students' learning by taking advantages of the recent advancement in personal IoT technologies of wearable devices in conjunction with using sports training approach to be applied to a group of members. Based on clustering students as an effective way of characterizing students, personal vital data and life log are to be integrated for judging on-going and even real-time status of students. A system will be developed based on this study to feedback necessary information and cautions to students. The study has achieved initial analysis on vital data obtained from wristband-type wearable devices in the three-year research project from 2016. © 2016 IEEE.

In this research, a new displaying and controlling method for three dimensional electronic texts using augmented reality via Leap Motion that is a very small and reasonable hand motion sensor is proposed. Recently, electronic texts in two dimensions have been popularized because of developed tablets with high quality display, easy storing and retrieving through the Internet better than paper media. However, it is difficult to understand contents written in separated pages, to feel physical thickness, to tie plural pages simultaneously, and to transform paper shapes or viewing angles. To cope with these difficulties, electronic texts become 3D model on web browsers and can be controlled in 3D via hand motions using a contact-less sensor in this research. As a result, operational feeling such as real paper media can be realized on PC. Our prototype system that can display 3D electronic texts and can be controlled via hand motions is presented. © 2016 IEEE.

Although blonanserin, a novel atypical antipsychotic agent with dopamine D2/serotonin 5-HT2A antagonistic properties, displays good brain distribution, the mechanism of this distribution has not been clarified. P-glycoprotein [(P-gp) or multidrug resistance protein 1 (MDR1)] is an efflux transporter expressed in the brain and plays an important role in limiting drug entry into the central nervous system (CNS). In particular, P-gp can affect the pharmacokinetics and efficacy of antipsychotics, and exacerbate or soothe their adverse effects. In this study, we conducted in vitro and in vivo experiments to determine whether blonanserin is a P-gp substrate. Risperidone and its active metabolite 9-hydroxyrisperidone, both of which are P-gp substrates, were used as reference drugs. Affinity of blonanserin, risperidone, and 9-hydroxyrisperidone for P-gp was evaluated by in vitro transcellular transport across LLC-PK1, human MDR1 cDNA-transfected LLC-PK1 (LLC-MDR1), and mouse Mdr1a cDNA-transfected LLC-PK1 (LLC-Mdr1a). In addition, pharmacokinetic parameters in the brain and plasma (B/P ratio) of test compounds were measured in mdr1a/1b knockout (KO) and wild-type (WT) mice. The results of in vitro experiments revealed that P-gp does not actively transport blonanserin as a substrate in humans or mice. In addition, blonanserin displayed comparable B/P ratios in KO and WT mice, whereas B/P ratios of risperidone and 9-hydroxyrisperidone differed markedly in these animals. Our results indicate that blonanserin is not a P-gp substrate and therefore its brain distribution is unlikely to be affected by this transporter. © 2012 Elsevier Inc.

Four species (capuchin monkeys, tree shrews, rats, and hamsters) performed an inference task situated in a social context. In Experiment 1, capuchin monkeys first explored food sites under 1 of 2 conditions: In 1 condition, food was refilled after it was eaten (replenished condition), whereas it was not refilled (depleted condition) in the other condition. Two food sites were presented for each condition. In the test phase, a subject watched a conspecific demonstrator visit 1 of the food sites in either the replenished or depleted condition. A screen placed in front of the sites prevented the subject from seeing the demonstrator actually eat the food. When the demonstrator was removed, the subject explored the cage. Three of 4 monkeys tended to go to the unvisited sites in the depleted condition, but tended to go to the visited site in the replenished condition. This suggests that they inferred that there was no food because the demonstrator had eaten it. In Experiment 2, using the same procedure, 2 nongroup-living species (tree shrews and hamsters) were indifferent to demonstrator behavior and visited sites only randomly, and group-living rats showed a strong tendency to follow demonstrators, irrespective of the type of food site. These tendencies were unchanged when olfactory information was added in Experiment 3 and when motivation to compete increased in Experiment 4. These results suggest that only capuchin monkeys have the ability to solve an inference task when cued by social information. © 2015 American Psychological Association.

For a software engineer, well-organized source code conveys the intention of the authors, as if it were an informal specification. An experienced engineer often grasps the 'pseudo' meaning of source code first by identifying semantic chunks of various granularities in it, then by weaving them into a hypothetically consistent semantics. We call the specific part in source code that realizes a semantic chunk a code pattern. Tool support for locating already defined code pattern would help engineer's understanding, but it has been practically difficult. One reason is that a code pattern may appear as a lot of slightly different variations. This becomes an obstacle to define a code pattern. In this paper, a framework for an implicit representation of a code pattern is presented. In the framework, a code pattern is defined by an enumeration of instances which is tagged either 'positive' of 'negative' by a human. From these sets, the system incrementally infers a hypothetical explicit (syntactic) definition of the code pattern. Each instance is represented as an anchored AST (abstract syntax tree. An anchored AST is an AST with a tuple of AST nodes of interest. © 2014 IEEE.

There are semantic chunks and relations (code patterns) of various granularities in source code. Since a code pattern is closely tied to a unit of understanding by a programmer, searching specific code pattern through unfamiliar souce code would help understanding the code. Conventional string search tools, however, are not suitable for this purpose because, for instance, they do not assume the syntax of a programming language. In this paper, a tool for search-by-example through abstract syntax tree is presented. A programmer gives sets of desired and undesired nodes, then the system presents some candidate nodes resembling desired ones. The method is supervised incremental learning of decision trees. © 2014 The authors and IOS Press. All rights reserved.

The Late Middle Eocene Pondaung Formation, central Myanmar hosts the richest deposit of terrestrial mammals in SE Asia. The Pondaung Formation contains anthropoid primates, such as Eosimiidae, Amphipithecidae and the new Afrotarsiidae, plus adapiform primates and is a critical locality in discussions on anthropoid origins and biogeography. The sands of the Pondaung Formation were derived from the erosional unroofing of a dissected andesitic volcanic arc and deposited on the forested floodplains of a large tropical river. Previously, the age of the Pondaung Formation was estimated to be Middle to Late Eocene based on stratigraphic evidence, Late Middle Eocene (Bartonian) based on comparisons with mammals from North America and Europe, 37.2. ±. 1.3. Ma and 38.8. ±. 1.4. Ma based on fission track dating and 37.4-37.0. Ma based on questionable magnetostratigraphic correlations. Here, we report a new LA-ICP-MS, U-Pb age for zircons from a tuffaceous bed in the Pondaung Formation of 40.31. ±. 0.65. Ma and 40.22. ±. 0.86. Ma which is slightly older than the debatable magnetostratigraphic ages of 37-36. Ma and 38-39. Ma for the anthropoids from Egypt and Libya. Pending the acquisition of similarly reliable radiometric dates from all the North African and Asian sites, this new date provides support for an Asian origin for the anthropoids. Our new dates are close to the molecular clock date for the origin of the anthropoid primates and may provide a reliable calibration point for the molecular phylogenetic method. © 2013 International Association for Gondwana Research.

The objective of this paper is to analyze the factors influencing the continuity of small-scale pig husbandry, which is practiced widely in hillside villages in continental Southeast Asia. For this purpose, we used the results of a case study in a hillside Hmong village in Nan province, northern Thailand. In particular, we examined the factors of continuity of small-scale pig husbandry by describing the following points: 1) the type of pigs villagers kept: 2) the type of feed given to the pigs; and 3) how the villagers used the pigs they kept. The results are outlined below. First, the main factor in the continuity of husbandry is that the villagers regularly use pigs for events with dual religious and social aspects. The religious aspect involves offering pigs in ritual sacrifice for an annual ancestor worship event while the social one is related to the use of pork in feasts for celebratory events, which play a role in reaffirming relationships with other villagers. Second, the main factor in small-scale husbandry relates to the techniques of collecting pig feed and the labor demanded for it. The number of pigs that can be kept by each household is regulated by the characteristics of freshness of plant feed, for example, banana leaves and stems, which are plentiful near the village but cannot be kept fresh for a long period of time. Therefore, villagers need to collect feed almost every day from the area around the village.

The ostracode genus Bicornucythere (Ostracoda, Crustacea) is abundant in modern-day eutrophic marine bays, and is widely distributed in estuaries and inner bays throughout East Asia, including in China, Korea, Japan, and the Russian Far East. The evolutionary history of Bicornucythere is poorly understood. Here, we report on a new species of Bicornucythere (Bicornucythere concentrica sp. nov.) from the upper Eocene Yaw Formation in the Central Myanmar Basin. The oldest previously known Bicornucythere taxon, Bicornucythere secedens, was reported from lower Miocene strata in India, although a molecular phylogeny suggests that the genus first appeared in the Late Cretaceous. Bicornucythere concentrica sp. nov. is at least 10.9 million years older than the earliest known B. secedens. The new species occurs with Ammonia subgranulosa, a benthic foraminifer, an association that is representative of brackish water conditions in modern Asian bays. Our findings indicate that extant genera have inhabited Asian bays since the late Eocene. The paleobiogeography of Bicornucythere indicates that the taxon was dispersed onto Indian coasts during the collision between the Indian and Eurasian plates.
