The photocurrent at the polarized water/1,2-dichloroethane (DCE) interface was successfully observed in the presence of a lipophilic sensitizer, 5,10,15,20-tetraphenylporphyrinato zinc (ZnTPP), in the organic phase. The photocurrent transient responses were apparently affected by the employed organic supporting electrolyte: tetrapenthylammonium tetraphenylborate (TPnATPB) or tris(tetraoctylammonium)tungstophosphate ((TOcA)3PW12O40). The photocurrent measured in the TPnATPB system exhibited rather slow responses associated with the ion transfer of photoproducts. On the other hand, the photoinduced heterogeneous electron transfer could be observed in the use of (TOcA)3PW12O40. The photocurrent intensity in the (TOcA)3PW12O40 system exhibited an apparent pH dependence and the photoreduction of hydrogen ions probably took place at the water/DCE interface. By analyzing the real and imaginary components of the photocurrent depending on the photoexcitation frequency, we roughly estimated the phenomenological rate constants of the product separation (kps) and recombination (krec) processes as log(kps/s-1) = 1.5 ± 0.2 and log(krec/s-1) = 1.8 ± 0.1, respectively.

In the past decade, much research has been focused on electroactive polymers (EAPs) as actuators. However, less well known is the fact that some of these materials have outstanding performance in the generator mode. Whereas polymer actuators convert electrical energy to mechanical energy, polymer generators convert mechanical energy to electrical energy. Many of the characteristics that make EAPs attractive as actuators also make them attractive as generators. Potential advantages include high energy output per unit mass, low cost, good coupling to many mechanical inputs, lightweight materials, and flexible design.We believe that given new capabilities enabled by EAPs, and the world's critical need for electrical power, that EAP power generation is an important focus area for research and development. Indeed, it is possible that EAP power generation could well exceed the importance of EAP actuators, itself an exciting technology area.

The purpose of this study was to verify the spatial distribution of myocardial repolarization heterogeneity using a newly developed 187-channel signal-averaged vector-projected ECG (187-ch SAVP-ECG). We constructed corrected recovery time (RTc) and Tpeak-end (corrected Tp-e) dispersion maps using a 187-ch SAVP-ECG based on vector-projection theory using a Mason-Likar lead system. We compared the spatial distribution and quantitative values of dispersion maps by 187-ch SAVP-ECG with those by 64-ch magnetocardiography (MCG) in 27 normal controls (control) and 16 patients (12 myocardial infarction (MI), and 4 dilated cardiomyopathy (DCM)). The wave pattern of the 187-ch SAVP-ECG in the representative cases was similar to those in 64-ch MCG. Spatial distribution increased RTc and corrected Tp-e dispersion maps defined by 187-ch SAVP-ECG were in agreement with those by 64-ch MCG. The value of RTc dispersion in MI was higher than that in control (41 ± 21 ms in MI versus 30 ± 12 ms in control, P < 0.05). The value of corrected Tp-e dispersion in DCM was higher than that in control (58 ± 12 ms in DCM versus 30 ± 13 ms in control, P < 0.001). There was a good correlation between RTc and corrected Tp-e dispersion values determined by 187-ch SAVP-ECG and 64-ch MCG modalities (y = 0.46x + 18, r = 0.62, P = 0.02 for RTc dispersion; y = 0.52x + 15, r = 0.63, P = 0.01 for corrected Tp-e dispersion). RTc and corrected Tp-e dispersion maps by 187-ch SAVP-ECG based on vector-projection theory can evaluate the spatial distribution of myocardial repolarization heterogeneity.

脛骨の変形治癒骨折に対して一期的に矯正骨切り術を施行後,locking plateを用いて内固定を行い良好な結果を得たので報告した.症例は58歳,男性.18歳時に交通事故で右脛腓骨骨折を受傷し,保存的治療を受けた.X線所見にて右膝の内側型変形性関節症を認め,脛骨上中1/3の部位にて約21°の内反変形を認めた.手術はまず腓骨を切骨し脛骨変形中心部にて骨切り,open wedgeにて矯正を行いlocking plateにて内固定を行った.術後6ケ月の現在,骨癒合良好で右膝痛も軽快しておりADLに支障はなく,正座も可能である.変形治癒骨折の矯正骨切術の方法としては従来のプレートによる方法では矯正位の獲得は容易であるがプレートのbendingを細かく行わないとスクリューで骨皮質をプレートに引き寄せる際に矯正位を失う可能性がある.locking plateにて内固定は矯正位の保持が容易であり有用であった.

The colloidal crystallization of fine particles is a phenomenon of great interest in connection with the research on the fabrication of photonic crystals. This paper describes a newly proposed method, in which self-arrangement and self-assembly of particles are generated under radiation force, i.e. gradient and scattering forces, and capillary force, respectively. The hexagonal structure in the Fourier-transformed patterns of 2D colloidal crystals shows that the triangular lattice structure is successfully fabricated by the proposed method. This paper is concerned with the principle of newly proposed method, capturing and self-arranging particles by radiation pressure, self-assembling particles by the desiccation process, the enlarging of colloid crystal, and the verification of the triangular lattice structure.

We compared the status of stress with and without metabolic syndrome in Japanese. We used data for 774 men and 1,136 women who had received annual health checkups at Okayama Southern Institute of Health. Status of stress was evaluated using a stress check provided by the Department of Public Health, Nihon University. Metabolic syndrome is defined by new criteria in Japan. Physical stress was significantly higher in men with metabolic syndrome than in men without it. However, the ability of coping with stress in men with metabolic syndrome was significantly higher than that in men without it. Thus a linkage between metabolic syndrome and the status of stress was characteristic in Japanese men.

The pain experienced by cancer patients can be managed in 70-90% of cases by the World Health Organisation protocol for cancer pain. However, cancer pain treatment in Japan is not sufficiently effective. To use medicine safely and effectively, various problems must be solved. Therefore, in this study, appropriate usage of cancer pain treatment was examined. We were able to use acetaminophen suppositories (800 mg each) in cancer pain patients. It was suggested that high serum concentrations of oxycodone and hydrocotarnine might be observed in geriatric patients or in the state of decreased hepatic blood flow, making dose adjustment is necessary for such patients. We also clarified that the conversion ratio from oral oxycodone to intravenous ocycodone/hydrocotarnine was 0.71±0.12. In addition, we clarified the pharmacokinetics of controlled-release oxycodone in patients with cancer pain. Moreover, the findings of our study indicate that in the steady state, the serum concentrations of fentanyl are not maintained at a constant level for 3 days following the use of transdermal fentanyl. We established a method of appropriately passing a nasal duct for sustained release of fine granules of morphine sulfate. Resolution of the clinical problems associated with cancer pain treatments is anticipated to allow the proper use of cancer pain treatments in Japan.

Insects, the largest group of animals on the earth, owe their prosperity to their ability of flight and small body sizes. The ability of flight provided means for rapid translocation. The small body size allowed access to unutilized niches. By acquiring both features, however, insects faced a new problem: They were forced to beat their wings at enormous frequencies. Insects have overcome this problem by inventing asynchronous flight muscle, a highly specialized form of striated muscle capable of oscillating at >1,000 Hz. This article reviews the structure, mechanism, and molecular evolution of this unique invention of nature.

In our definition, human activity can be expressed by five basic attributes: actor, action, object, time and location. The goal of this paper is describe a method to automatically extract all of the basic attributes and the transition between activities derived from sentences in Japanese web pages. However, previous work had some limitations, such as high setup costs, inability to extract all attributes, limitation on the types of sentences that can be handled, and insufficient consideration interdependency among attributes. To resolve these problems, this paper proposes a novel approach that uses conditional random fields and self-supervised learning. Given a small corpus sample as input, it automatically makes its own training data and a feature model. Based on the feature model, it automatically extracts all of the attributes and the transition between the activities in each sentence retrieved from the Web corpus. This approach treats activity extraction as a sequence labeling problem, and has advantages such as domain-independence, scalability, and does not require any human input. Since it is unnecessary to fix the number of elements in a tuple, this approach can extract all of the basic attributes and the transition between activities by making only a single pass. Additionally, by converting to simpler sentences, the approach can deal with complex sentences retrieved from the Web. In an experiment, this approach achieves high precision (activity: 88.9%, attributes: over 90%, transition: 87.5%).

A study was made on cancer mortality in the high-background radiation areas of Yangjiang, China. Based on hamlet-specific environmental doses and sex- and age-specific occupancy factors, cumulative doses were calculated for each subject. In this article, we describe how the indirect estimation was made on individual dose and the methodology used to estimate radiation risk. Then, assuming a linear dose response relationship and using cancer mortality data for the period 1979-1995, we estimate the excess relative risk per Sievert for solid cancer to be -0.11 (95% CI, -0.67, 0.69). Also, we estimate the excess relative risks of four leading cancers in the study areas, i.e., cancers of the liver, nasopharynx, lung and stomach. In addition, we evaluate the effects of possible bias on our risk estimation.

Fluorescent sensor molecules were synthesized by conjugation of iminodiacetamide derivatives with fluorescent moieties of different structures and their UV-visible and fluorescent properties were characterized in acetonitrile solvent. The fluorescent measurements revealed that the N-(2-naphthyl) and N-phenyl derivatives exhibit a distinct zinc ion-selectivity over alkali and alkaline earth metal ions, while N-(anthrylmethyl) and N-(3-methoxyphenyl) derivatives do not possess any ion-selectivities. In contrast to the fluorescent measurements, all ligands show Zn2+ selectivity over Ca2+ and Mg2+ ions in plasticized PVC membranes using potentiometric signal transduction. This observation found for N-(anthrylmethyl) and N-(3-methoxyphenyl) derivatives can be ascribed to the more hindered interaction between the signalling group of the ionophore and the central metal ion in PVC membranes than in acetonitrile solution upon complexation. From the fluorescent measurements it can also be concluded that the ligands with metal ions form complexes mainly with 2:1 stoichiometry (L2M). On complex formation a considerable decrease in the fluorescent intensity was observed for all ligands except the N-(anthrylmethyl) derivative, where a 25 - 30 fold fluorescence enhancement was found, which is explained by the photoinduced electron transfer (PET) mechanism. All ionophores exhibited serious hydrogen ion interference, therefore complexation-induced spectral changes were measured in aprotic acetonitrile solution.

考古学の遺跡発掘調査で地震の痕跡が見つかることが多いが、従来は調査の対象とされずに見逃されていた。筆者は、1988年に「地震考古学」を提唱し、遺跡の地震痕跡を用いた研究方法を広く普及させた。これによって、考古学と地震関連分野との境界領域が開拓されて様々な成果が得られた。南海トラフで発生する巨大地震について過去2千年間の発生年代がわかり、次の発生を考える基礎資料となった。内陸の活断層による地震痕跡も数多く見出されており、京阪神・淡路地域では1596年慶長伏見地震での地盤災害が詳しくわかった。液状化現象についても、遺跡での観察結果から新しい知見が得られた。また、地震痕跡は一般市民にも理解しやすいことと、マスメディアにも取り上げられる機会も多いことなどにより、地震災害軽減のための活動へ大きく寄与している。

We examined the effect of stable iodine on thyroid gland blockade in patients with hyperthyroidism in order to make a preliminary evaluation of the appropriate dose of iodine prophylaxis in the event of a radiation emergency in Japan in which radioiodine is released to the environment. Eight patients were orally given single doses of 50 mg or 100 mg of potassium iodide, which contained 38 mg and 76 mg of iodide, respectively. Both doses significantly suppressed a thyroid uptake of 123I for 24 h (p = 0.03). The protective effects at 24 h were 73.3% and 79.5%, respectively. No side effects were observed during the trial. The present study demonstrates that a single oral administration of 38 mg of iodide produces a thyroid-blocking effect equivalent to that of 76 mg of iodide, suggesting that a reevaluation of the stable iodine dosage during radiation emergencies in iodine-rich areas such as Japan is warranted.

It is ideal to provide medical services as patient-oriented. The medical staff members share the final goals to recover patients. Toward the goals, each staff has practical knowledge to achieve patient-oriented medical services. But each medical staff has his/her own sense of value that comes from his/her expertness. Therefore the practical knowledge sometimes conflicts. The aim of this research is to develop an intelligent system to support externalizing practical knowledge, and sharing it among medical staff members. In this paper, the author propose a method to model the sense of value of each medical staff as his/her understanding about medical service workflow, and to obtain the practical knowledge using the models. The method was experimented by an implementation of knowledge-sharing system base on the method and by its trial use in Miyazaki University Hospital.
