Direction of rupture propagation φ and fault length L for the 1994 Sanriku-Haruka-Oki earthquake are evaluated from the azimuthal dependence in duration of strong ground motion observed at eleven stations along the Pacific coast of Tohoku and Hokkaido region. After defining the strong motion duration D as the time interval between onset of S wave and 85% of cumulative power curve derived from 5 to 10Hz band-pass filtered accelerogram, the azimuthal dependence of D is examined. We find that D systematically shows directivity: D is the shortest at northern part of Tohoku and the longest at southern part of Tohoku and eastern edge of Hokkaido. By making use of the directivity on observed strong motion durations, we apply the method by IZUTANI and HIRASAWA (1987) to deducing φ and L together with VR/β, where VR and β are rupture velocity and S wave velocity. Assuming that rupture initiated from the epicenter determined by the Japan Meteorological Agency (JMA), we obtain L/VR=53, VR/β=0.62, and φ=W9°N (case 1). This result indicates that the rupture was headed toward northern part of Tohoku, and terminated near the western end of aftershock area. Detailed source-process inversion [for example, SATO et al. (1996)] suggests that main rupture nucleated near the center of aftershock area, corresponding to the epicenter determined by Harvard University. We redo the calculation assuming that the rupture initiated from the Harvard epicenter, then resulting in L/VR=28, VR/β=0.71, and φ=W18°N (case 2). This result also indicates that the rupture propagated toward northern part of Tohoku, and terminated at the western end of aftershock area. SATO et al. (1996) suggest that this earthquake consists of threestage rupture process: the first and the second sub-events corresponding to JMA and Harvard epicenter, respectively, and the third sub-event located near the western end of aftershock area at the distance of about 50km from Hachinohe city. The location where rupture terminated in both cases of this study is consistent with the location of the third sub-event, confirming that the rupture extended to the western end of aftershock area.

“Aseri” is a Japanese term referring to an emotional state of “being impatient” or “feeling time urgency” that is experienced in everyday life. This study explored how people in early adulthood experienced aseri in their daily lives. Interviews were conducted with twenty young adults who recalled events or situations involving aseri. Grounded theory was referred in collection and analysis of data. The results showed that aseri developed in situations where there were several competing thoughts. Regarding the process in which aseri changed, two patterns were found: (a) when aseri was strongly experienced in the short term, it settled down easily; (b) when aseri was felt mildly in the long term, it gradually became latent. The theme of latent aseri reflected the developmental tasks of early adulthood that were considered significant for the participants including developmental tasks typically achieved in adolescence that were put off until early adulthood. Implications for aseri and directions for further research are discussed.

Due to the Geiyo Earthquake in March 24th, 2001, center stay rods of the 1st Kurushimakaikyo Bridge(suspension bridge) were broken. They were designed to break in strong earthquake and work as safety valve of the structure. In order to evaluate the mechanism of the breakage of the rods, data from field measurement were processed using structural analysis, and it was confirmed that the broken rods worked as designed. It also was confirmed that forces acted to other unbroken rods in 2nd and 3rd Kurushimakaikyo Bridges were not large enough to affect their soundness. Through this experience, it was proven that field measurements and structural analysis can be effective tools not only for design but also for maintenance of structures.

Background: Target anticoagulation levels for warfarin in Japanese patients with non-valvular atrial fibrillation (NVAF) are unclear. Methods and Results: Of 7,527 patients with NVAF, 1,002 did not receive warfarin (non-warfarin group), and the remaining patients receiving warfarin were divided into 5 groups based on their baseline international normalized ratio (INR) of prothrombin time (≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0). Patients were followed-up prospectively for 2 years. Primary endpoints were thromboembolic events (cerebral infarction, transient ischemic attack, and systemic embolism), and major hemorrhage requiring hospital admission. During the follow-up period, thromboembolic events occurred in 3.0% of non-warfarin group, but at lower frequencies in the warfarin groups (2.0, 1.3, 1.5, 0.6, and 1.8%/2 years for INR values of ≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0, respectively; P=0.0059). Major hemorrhage occurred more frequently in warfarin groups (1.5, 1.8, 2.4, 3.3, and 4.1% for INR values ≤1.59, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0, respectively; P=0.0041) than in non-warfarin group (0.8%/2 years). These trends were maintained when the analyses were confined to patients aged ≥70 years. Conclusions: An INR of 1.6–2.6 is safe and effective at preventing thromboembolic events in patients with NVAF, particularly patients aged ≥70 years. An INR of 2.6–2.99 is also effective, but associated with a slightly increased risk in major hemorrhage. (UMIN Clinical Trials Registry UMIN000001569)

The purpose of the study was to describe the clinical and electroretinographic features of clinical cases of progressive retinal atrophy (PRA) in miniature schnauzer (MS) of South Korea. Sixty-six MS (14 normal and 52 affected) were included. All animals underwent routine ocular examinations. Electroretinogram (ERG) was recorded in the 14 normal and 15 affected dogs. For normal dogs, the mean age ± SD was 4.1 ± 2.4 years (1 to 9 years), and there were no ocular abnormalities on the basis of ocular examinations and ERG results. For the PRA-affected dogs, it was shown that the mean age ± SD was 4.3 ± 1.1 years (2 to 7 years), and 44 dogs (84.6%) were 3 to 5 years old. Most of the PRA-affected dogs had abnormal menace responses (98.1%) and pupillary light reflexes (PLRs, 88.5%); some dogs showed normal menace response (1.9%) and PLRs (11.5%). Ophthalmoscopic abnormalities in the affected group included one or more of the following changes: hyperreflectivity and discoloration of the tapetal area, attenuation of retinal vessels, depigmentation in non-tapetal area and optic disc atrophy. ERG in the affected dogs showed non-recordable responses in all cases tested with clinical signs of PRA. The present study showed that PRA in MS was mainly observed between the age of 3 to 5 years. ERG revealed abnormal rod and cone responses in affected dogs at the ages studied.

Canine aggression is one of the behavioral problems for which veterinary behaviorists are most frequently consulted. Despite this, the classification of canine aggression is controversial, and there are several classification methodologies. While the etiology of canine aggression differs among the types of aggression, the behavioral background underlying aggression is not well understood. Behavior trait-based evaluation of canine aggression would improve the effectiveness and efficiency of managing canine aggression problems. We developed a questionnaire addressing 14 behavioral items and items related to four types of canine aggression (owner-, child-, stranger- and dog-directed aggression) in order to examine the associations between behavioral traits and aggression in Shiba Inu. A total of 400 Shiba Inu owners recruited through dog events (n=134) and veterinary hospitals (n=266) completed the questionnaire. Factor analysis sorted the behavioral items from both the event and clinic samples into four factors: “sociability with humans,” “reactivity to stimuli,” “chase proneness” and “fear of sounds.” While “reactivity to stimuli” correlated significantly positively with all of the four types of aggression (P=0.007 to <0.001), “sociability with humans” correlated significantly negatively with child- and stranger-directed aggression (P<0.001). These results suggest that the behavioral traits involved in canine aggression differ among the types of aggression and that specific behavioral traits are frequently simultaneously involved in several types of aggression.

When making paddy fields on a slope, the paddies, each with a level surface, must be made one by one in the form of a series of shelves or terraces. Paddy fields made in this manner are called “terraced paddy fields” or “shelf paddies” “tanada” in Japanese. Such paddy fields are found in various parts of the mountainous regions of Japan, and may roughly be divided into two categories, depending on the nature of the place where they are found. The first category includes terraced paddy fields that stretch in long, narrow lines along the bottom of small valley among the mountains. To the second category belong those that are found stretching on wide slopes. Terraced paddy fields belonging to the first category are found everywhere in mountainous regions. They are easy to make and their irrigation presents no problems. In the case of terraced paddy fields of the second category, however, because of the general complexity of the relief of the slopes where they are found, their making in such places requires great labor, and their irrigation is a difficult matter.The present writer conducted a study of 26 of the main terraced paddy fields belonging to the second category, and in each case, was convinced of the great pains and resourcefulness required to ensure the supply of irrigation water.In Japan, rice has been the main food crop since ancient times ; and until the Meiji period, it was the practice among farmers to pay their taxes in rice. Rice was the all-important element of economy, both for the central and local feudal lords until the Meiji period. This was the reason that, throughout the nation, the development and expansion of paddy fields were the two main concerns of the rulers as well as the farmers. This state of affairs continued until recent times. The present writer believes that it is possible to consider the existence of terraced paddy fields as one of the manifestations of the history of this type of rice-centered policy in the form of cultural landscapes seen in the land.In the present paper, the writer has chosen three typical regions, and he purposes to describe the development of the irrigation of the terraced paddy fields found in each of these regions.(1) The Wajima Region in the northern part of the Noto Peninsula.This region is the location of “Shirayone no Senmaida” (or “Numerous Small Terraced Paddy Fields of Shirayone”), which in recent years have come to attract the attention of tourists. There are monographs and books which state that the terraced paddy fields in this region are supplied with irrigation water by springs and rain water. The writer, however, has made clear in the present paper the fallacy of these claims. In the Edo period, in order to irrigate the terraced paddy fields in this region, long irrigation canals were dug to draw irrigation water from the upper reaches of rivers among the mountains, while irrigation reservoirs were made among the mountains to provide irrigation water. Examples of these irrigation systems are shown in Figures 1 and 2. The terraced paddy fields in this region are developed on slopes formed as a result of landslides.(2) The Obasute Region in Nagano Prefecture.This region is the location of terraced paddy fields widely reputed as “Tagoto no Tsuki” (or “The Moon Reflected in Each of Many Paddy Fields”). In this region, too, are found terraced paddy fields on slopes formed as a result of landslides. Concerning the terraced paddy fields in this region, there are books which state that they were supplied with irrigation water by springs and rain water, but the irrigation system in this region is not such a simple matter.

Hypofractionated radiotherapy(27-32 Gy/3-4 fractions)was performed in the 3 dogs diagnosed as plasma cell tumors, since complete resection by surgical operation was impossible. In all cases, their tumors were disappeared within 1 to 4 months after radiotherapy. In case1, recurrence has not been noted during a follow-up period of 19 months. Cases 2 and 3 have not showed recurrence for 13 and 6 months, respectively. These results indicated that hypofractionated radiotherapy is effective for canine plasma cell tumors, since reduction of the local mass was seen within a few months.

An invention of the new physical battery called ECS (Energy Capacitor System) composed from specially made capacitors and electronic circuits, has opened up profound applications and possibilities. Copernican revolution indesign of energy storage capacitors is provided by trading off their internal resistance with energy density, and by charging slowly as to obtain better efficiency. Many problems inherent to capacitors such as inefficient charging, wide variation of terminal voltage and unequal distribution of voltage to each capacitors have been solved by attached electronic cirCapacitors for the system are also specially developed. With the electronic circuits, capacitors accommodate the energy density of 10Wh/1 at 2ΩF (ohms for each farad) and 18 Wh/1 at 108ΩF. Various applications are tested ranging from solar system to home air conditioner. Power load leveler is supported by Japanese national project, a 3kWh system is built and resulted 85% AC to AC, 95% DC to DC efficiency together with record cell energy density of 27 Wh/l. A 15ton Hybrid bus powered by a 75kW ECS with a 75kW generator produced and resulted almost twice improvements of fuel mileage.

The purpose of this paper is to analyze the current state of developmental researches in the area of psychophysiology of emotions in preschool and elementary school children. Electrodermal and cardiovascular activity measures are considered as the sources of indices of the autonomic nervous system activation during emotion-eliciting stimulation in children. We discuss the question of sensitivity of phasic and tonic autonomic measures for the identification of occurrence of emotion, mapping it along with valence and arousal dimensions in affective space, and to further differentiate emotions by their physiological manifestations. Considered are the conceptual and methodological issues related to psychophysiological measurements and developmental factors affecting the emotional reactivity in children. Special attention is devoted to the developmental aspects of psychophysiological studies on emotion such as the maturation of organs, integration of the autonomic and central nervous systems, age and gender-related changes in autonomic reactivity, and development of inhibitory control. Summarized are main findings relevant to psychophysiology of emotions in preschool and early school-age children and suggested are most perspective directions of their integration in the framework of modern theories of emotion.

Three cases of colorectal foreign bodies are presented and the literature is reviewed. Case 1: A 47-year-old man, who had inserted a seasoning bottle in his rectum on January 3, was admitted to National Yokosuka Hospital on January 5, 1990. A pelvic x-ray film showed the object in the sigmoid colon, and an emergency operation was performed. The bottle (11cm in length) was removed from the sigmoid colon. The patient was discharged 16 days after the operation without complications. Case 2: A 40-year-old man presented with a self-inserted seasoning bottle in his rectum that he was unable to remove and was admitted to the hospital on July 24, 1990. Edema of the rectum precluded manual removal of the object. At laparotomy, the bottle (7.5cm in length) was removed from the rectum. The patient's postoperative course was good and he was discharged on August 26. Case 3: A 62-year-old man was admitted on December 12, 1990 for evaluation of a one-day history of a foreign body in the anorectum following autoerotic transanal manipulation with a vibrator. The 6×3×3cm object was removed manually after a spinal anesthetic. The patient was discharged on the third postoperative day.
