In this study, we investigated effects of having different perspectives in solving collaborative tasks. A simple reasoning task was given to several pairs of participants, each of whom discussed their views with their partner. Protocol analysis was performed to reveal how people exchange information with a partner who has a different perspective to achieve successful collaboration. In the experiment, we controlled participants′ perspectives, where the appearance of visual images was manipulated based on Gestalt psychological theory. Three conditions were set up: (1) the distributed-view condition, where one of two different perspectives was presented separately to each of the participants in a pair; (2) the dual-view condition, where two equivalent perspectives were presented together to both participants; and (3) the single-view condition, where only a single perspective was presented to both participants. The protocol analysis showed that the pairs in the distributed view condition who reached to solution engaged in the task with complementary interactive manners. On the other hand, the protocols of the pairs who could not reach solution showed that one of the participants shifted his⁄her perspective towards the opponents′ perspective. It is also argued that the problem solving in collaboration of pairs with different perspectives is performed through insight processes.

Brucella infections in wildlife originate either from contact with infected livestock or from a natural sustainable reservoir in wildlife populations. As South Korea has set a goal of brucellosis eradication by 2013, it is necessary to determine the prevalence of Brucella in wildlife and wild rodents. This information will play an important role in the control of brucellosis. Because of the absence of prominent clinical signs, direct and indirect laboratory tests are essential for diagnosing brucellosis. In this study, tissue and blood samples were taken from wild animals, abandoned dogs, a cat and wild rodents, and they were tested for Brucella or Brucella-specific antibodies by isolation, PCR and serology. Results showed that 18.6% (33/177) of blood samples were positive by PCR, and 5.7% (11/194) were positive by C-ELISA. However, none of these samples yielded culturable bacteria. Of the tissue samples, 9.7% (8/82) were positive by PCR. Brucella was isolated from only one tissue culture from a Chinese water deer carcass. This Brucella species was identified as Brucella abortus biovar 1 by biotyping, 16S rRNA PCR and the Bruce-ladder PCR assay. In this study, we reported the prevalence of Brucella in wildlife, dogs, a cat and rodents by using serological and molecular methods, and we report the first isolation of B. abortus in wild Chinese water deer in South Korea.

我が国においては2002年をピークに, 「食」が大きな社会問題となった. 本論文は, このかつてない「食品パニック」が形成されるに至ったメカニズムの解明を試みるものである. 具体的には, まず, 最大の「トリガー」となったBSEに関して, 何故ゆえにそのような社会的インパクトを持ちえたのかを, BSEの疾病としての特殊性を検討することで明らかにした. 更に, BSE問題がある程度収束した後に食品問題のピークが現れている点にも注目し, それらを構成する事例を詳細に検討した. これにより, 食品問題の増加は当該時期に新たなリスクが生じたというよりも, BSEを契機に社会的なアジェンダが「食」に誘導され, 注目が集まった結果, 古くから存在する食の問題群が掘り起こされたと見ることに妥当性があることを論じた. 最後に, これらの知見を踏まえ, 今後の類する問題解決のための一定の方向性を示した.

Enzymatically synthesized glycogen (ESG) has high solubility and its solution has low osmotic pressure. Therefore ESG solution could be rapidly absorbed and could be adequate for water rehydration and carbohydrate supplementation during exercise. The object of this study was to evaluate the gastric emptying time and plasma glucose elevation after an administration of ESG solution in comparison with another carbohydrate solution by using a laboratory animal. Male BALB/c mice were administered 10% w/v solution of glucose, maltodextrin, starch, naturally synthesized glycogen (NSG) and ESG at a dose of 20 μL/g body weight for the measurement of gastric emptying rate (Experiment 1) and 10 μL/g body weight for the measurement of plasma glucose elevation (Experiment 2). The osmolarity of gastric content was lower in the ESG and maltodextrin group than the other carbohydrate group. Weight of gastric fluid was significantly lower in the ESG and water group than the glucose group (p<0.01). Plasma glucose level was significantly lower in the ESG group than the glucose group from 0 to 60 min after administration (p<0.01), whereas plasma glucose level was same from 60 to 120 min for the ESG and glucose group (p=0.948). In Experiment 3, BALB/c mice ran on a treadmill for 2 h and were administered 8% of ESG or glucose solution (1.75, 3.5 or 7.0 μL/g body weight) every 20 min during running. There was no difference in post-exercise muscle glycogen level. These data suggest that 1) ESG beverage does not disturb water absorption because of its short gastric emptying time and 2) ESG slowly elevates plasma glucose level and maintains it for a prolonged time compared to the glucose solution.

We evaluate the size distribution of fine water droplets produced by electrostatic atomization using a differential mobility analyzer (DMA) and a condensation nucleus counter (CNC) . Broad size distribution with the peak of mobility diameter of around 15-20 nm is observed for the neutralized polydisperse water droplets. The number of charge is analyzed using a tandem DMA system. The water droplets are highly charged depending on the particle size. The number of maximum electric charges is 14, which is well below the Rayleigh limit.

Background Tenascin-C (TN-C), an extracellular matrix glycoprotein, is specifically expressed at high levels during embryonic development, but not in the adult heart. TN-C reappears at sites of inflammatory tissue remodeling or wound healing under various pathologic conditions, such as acute myocardial infarction, acute myocarditis, and some cases of cardiomyopathy. Therefore, the expression of TN-C might be useful for detecting the clinical characteristics of, and ventricular remodeling in, dilated cardiomyopathy (DCM). Methods and Results Circulating serum TN-C levels in 107 patients with DCM were measured using an ELISA kit. Clinical data were also assessed by Pearson's or Spearman's correlation analysis to estimate correlations between variables. Serum TN-C levels in DCM patients were higher than those in normal controls (p<0.001). TNC levels showed a significantly positive correlation with New York Heart Association functional class (p<0.001), B-type natriuretic peptide level (p<0.001), cardiothoracic ratio on chest X-ray (p<0.01), left ventricular end-diastolic diameter (p<0.05) and left ventricular end-systolic diameter (p<0.01), and a significantly negative correlation with left ventricular ejection fraction (p<0.01). Conclusions The findings suggest that increased serum TN-C levels indicate the severity of heart failure, left ventricular dysfunction and remodeling in patients with DCM.

We tried the decontamination of surface soils for three types of agricultural land at Nagadoro district of Iitate-mura (village) in Fukushima Prefecture, which is highly contaminated by deposits of radionuclides from the plume released from the Fukushima Daiichi nuclear power plant. The decontamination method consisted of the peeling of surface soils solidified using a polyion complex, which was formed from a salt solution of polycations and polyanions. Two types of polyion complex solution were applied to an upland field in a plastic greenhouse, a pasture, and a paddy field. The decontamination efficiency of the surface soils reached 90%, and dust release was effectively suppressed during the removal of surface soils.

To promote the understanding of succession process in artificial urban ecological environments, we invested the changes in bryophyte flora in an urban afforested woodland in Kyoto city. Focusing on three bryophyte functional groups (substrate preference, growth form and reproductive type), we compared the bryophyte flora in 2002 with those in 2007. A total of 41 species were recorded in 2002, and 52 species in 2007. The number of bryophyte species on trunk increased markedly compared to those of bryophyte speceis on other substrates, while bryophytes on rock showed higher turn over rate.From a view point of growth forms, bryophytes of cushion form, thread-like form, small-size appressed form and thalloid form increased greater than bryophytes of other growth forms, and bryophytes of small turf form and squamous form had a higher turn over rate. Additionally, the number of bryophyte species with asexual reproduction invaded more frequently than those of bryophyte species without asexual reproduction. These differences were explained by characteristic of bryophyte functional groups. In conclusion, to restore bryophyte vegetation in this study site based on the concept of potential natural vegetation, planting trees around the site, placing large rocks in the site and maintenance such as weeding were considered to be effective for the restoration of native bryophyte vegetation. Moreover, it was possible that introducing bryophyte species with poor dispersal ability into this site was needed for the restoration.

The purpose of this study was to replicate the applicability of the Gwinner and Bennett model (2008) which examined the effects of brand cohesiveness and sport identification on sponsor fit in a sponsorship in a Japan context. This study analyzed also focusing on the impact of sponsor fit on two important consumer behavioral outcome; attitude toward sponsors and purchase intentions. The data were collected from 537 spectators at the HP JAPAN WOMEN'S OPEN TENNIS 2009 in Osaka. The results of study indicate that brand cohesiveness and sport identification also have strong impacts on the sponsor fit at the event. Findings also support our hypotheses that sponsor fit has a positive influence on consumers purchase intentions through the attitude toward sponsor. It can be concluded that the Gwinner and Bennett model is applicable to the sponsorship in a Japanese context.

In recent years, when art and design students have the chance to be involved in film production they tend increasingly to produce animations. Young artists and professional designers are also showing a positive interest in animation and have been developing their own techniques of production. Focusing from a high-level perspective on the series of production processes involved in time-based visual media and explicitly defining these processes as design, this paper argues that artists and designers need to establish their own methods of “design for designing”. The preparation of visual design materials in the preliminary stages of animation production is essential for developing ideas and passing these on to subsequent processes. Such consciousness concerning the importance of the objective visualization of ideas can make a valuable contribution to the originality of the creative work itself. Introducing the practice of “Frame-by-Frame Shooting” in design education, this paper considers the contribution which the use of moving images, especially animation, can make to the design process. The paper also discusses the effectiveness of self-observation in the process of “design for designing” with reference to the concept of meta-cognition. This discussion is intended to address some hitherto under-researched questions concerning moving images in the field of cognitive science.

Relational similarity can be defined as the similarity between two semantic relations R and R' that exist respectively in two word pairs (A,B) and (C,D). Relational search, a novel search paradigm that is based on the relational similarity between word pairs, attempts to find a word D for the slot ? in the query {(A,B), (C,?)} such that the relational similarity between the two word pairs (A, B) and (C, D) is a maximum. However, one problem frequently encountered by a Web-based relational search engine is that the inherent noise in Web text leads to incorrect measurement of relational similarity. To overcome this problem, we propose a method for verifying a relational search result that exploits the symmetric properties in proportional analogies. To verify a candidate result D for a query {(A, B), (C, ?)}, we replace the original question mark by D to create a new query {(A,B),(?,D)} and verify that we can retrieve C as a candidate for the new query. The score of C in the new query can be seen as a complementary score of D because it reflects the reliability of D in the original query. Moreover, transformations of words in proportional analogies lead to relational symmetries that can be utilized to accurately measure the relational similarity between two semantic relations. For example, if the two word pairs (A,B) and (C, D) show a high degree of relational similarity then the two word pairs (B,A) and (D,C) also have a high degree of relational similarity. We apply this idea in relational search by using symmetric queries such as {(B, A), (D, ?)} to create six queries for verifying a candidate answer D to improve the reliability of the verification process. Our experimental results on the Scholastic Aptitude Test (SAT) analogy benchmark show that the proposed method improves the accuracy of a relational search engine by a wide margin.

This study focuses on the similarities and differences of the work values among the peoples studies in our East Asia Value Survey conducted during 2002-2004. It shows useful aspects of cross-national comparison on the East Asia.Some researchers consider that the East Asia is under the influence of Confucianism, as the western countries under the influence of Christianity. It is said that scholars and civil servants are more respected than practical workers in Confucian ethics. Therefore, Maoism in China emphasized practical workers (farmers and labors) more respected. On the other hand, Confucian ethics of Japan was accepted among samurai (warrior)'s ethics at Edo era, may have been lost in the stream of democratization after Meiji era and in the reorganization after World War II. The questionnaire of our East Asia Value Survey included two open questions about the occupation: “What occupation do you respect most ?”; “What is the occupation you yourself would like to have ?” The results of these responses indicate that the three categories as “Teacher”, “Medical Doctor” and “None or Don't Know” are useful criteria for the comparison among East Asian Peoples.

This article reviews and discusses various ways to strengthen the linkage between mathematical sociology and empirical research. It distinguishes between the use of mathematics in sociology for theory construction and for empirical data analysis, and discusses how the linkage has been made and how it can be strengthened in each category of use. Concerning the use of mathematics for theory construction, the article compares the integrated division of labor between theory construction and empirical research to traditional divisions of labor, emphasizing the relative importance of the former. Concerning the use of mathematics for data analysis, the paper identifies (1) indexing and measurement, (2) mathematical methods for heuristic analysis of qualitative data, (3) substantively motivated statistical models, and (4) hybrids of mathematical and statistical models, as four forms of linkage between mathematical sociology and empirical research, discussing the accomplishment and prospects for the future for each form.

本研究では,大都市沿岸域に造成された潟湖型の干潟である「東京港野鳥公園・潮入りの池」において,夏期2潮汐間の水質調査を3年間行い,干潟域における窒素・リン・クロロフィルαの収支,動態について検討した.また,飛来した水鳥の個体数と,底生動物の現存量の調査を行い,干潟域の生物相を把握した.調査の結果,当該干潟は夏期に,リンの供給源,窒素・クロロフィルαの消費源として機能しており,堆積物と直上水間の無機態窒素,リンの交換フラックスは干潟全体の収支の主要因であることが明らかになった.干潟域には年間を通してカワウの飛来数が数多く観測された.水鳥が干潟系外へ持ち去るTN量は最大でも,夏期に水中から除去されるTN量の12%程度,TP量は最大でも隣接海域へ流出するTP量の10%程度と,その値は小さかった.

野鳥の分布とその関連情報をWebで提供するGIS (地理情報システム)の典型例として,アジアの鳥類分布データベース:BirdBaseがあり,2004年から公開されている.同システムはArcIMSの当時の版を用いて構築されており,その後に実現し,注目されているGoogle Maps API技術は用いていない.BirdBaseは野鳥の分布とその鳥の生息環境を示す土地利用情報を検索表示する総合システムであるが,野鳥の分布と土地利用情報を同時に見やすい形で表示することは容易でない.そこで,Google Maps API関連技術を用いた野鳥分布と土地利用情報を検索表示するシステムを試作した.野鳥分布データベースはBirdBaseの開発・運用機関:北海道立総合研究機構環境科学研究センターから許可を得て,北海道の野鳥のデータに限定して期間限定で借用した.
