For the detection of generic objects in the field of image processing, histograms of orientation gradients (HOG) is discussed for these years. The performance of the classification system using HOG shows a good result. However, the performance of using HOG descriptor would be influenced by the detecting object size. In order to overcome this problem, we introduce a kind of hierarchy inspired from the convolution-net, which is a model of our visual processing system in the brain. The hierarchical HOG (H-HOG) integrates several scales of HOG descriptors in its architecture, and represents the input image as the combinatorial of more complex features rather than that of the orientation gradients. We investigate the H-HOG performance and compare with the conventional HOG. In the result, we obtain the better performance rather than the conventional HOG. Especially the size of representation dimension is much smaller than the conventional HOG without reducing the detecting performance.

There is strong demand to create wearable PC systems that can support the user outdoors. When we are outdoors, our movement makes it impossible to use traditional input devices such as keyboards and mice. We propose a hand gesture interface based on image processing to operate wearable PCs. The semi-transparent PC screen is displayed on the head mount display(HMD), and the user makes hand gestures to select icons on the screen. The user's hand is extracted from the images captured by a color camera mounted above the HMD. Since skin color can vary widely due to outdoor lighting effects, a key problem is accurately discrimination the hand from the background. The proposed method does not assume any fixed skin color space. First, the image is divided into blocks and blocks with similar average color are linked. Contiguous regions are then subjected to hand recognition. Blocks on the edges of the hand region are subdivided for more accurate finger discrimination. A change in hand shape is recognized as hand movement. Our current input interface associates a hand grasp with a mouse click. Tests on a prototype system confirm that the proposed method recognizes hand gestures accurately at high speed. We intend to develop a wider range of recognizable gestures.

After implementation of the new GCP, our hospital was staffed by clinical research coordinators (CRC) to smoothly conduct clinical trials of higher quality. At present, two pharmacists, two dental hygienists, and one nurse are working concurrently as CRCs in our hospital. An unique feature of CRC work at our hospital include 1) dental hygienists working as CRCs, and 2) CRCs of different specialities are coordinated on the same trial and contributing according to their specialties, participation of each clinical trial, one by one. Previously, in our hospital, clinical trials for medications had been allocated to nurse CRCs, while dental hygienist CRCs support for clinical trial of medical devices. However, a dental hygienist have participated as a CRC for the first time in a clinical trial for a medication in 2009, a pharmacist CRC cooperated the clinical trial with the dental hygienist CRC, and this trial was successfully completed. We anticipate that dental hygienist CRCs supporting clinical trials in dental practice will play an indispensable role in smoothly conducting clinical trials with high quality. In this report, we will present the current status of CRC work, which has been accomplished by cooperation with pharmacists and dental hygienists.

The purpose of this study was to examine two relationships; one between the serum zinc concentration and the intake of zinc, and the other between the serum zinc concentration and the hematological consistent associated with the serum zinc concentration in elderly patients in a health facility.  The estimations of the hematological consistent, physical index, and dietary survey were made based on an examination carried out on 15 disabled elderly patients (male=8, female=7, mean age 82±10 years) .  The obtained results from this study are summarized as follows:1) The subjects showed low levels of serum zinc, although the intake of zinc was close to the recommended dietary allowance (RDA) level.2) The ratio of the subjects of less than 66 μg/dl of the reference value of the serum zinc was 60% for men and 72% for female in the oral feeding, and also 100% of men and 83% of female in the enteral feeding.3) The three significant correlations was found between the serum zinc and the hematocrit, the serum zinc and total protein, and the serum zinc and albumin values.  As a high percentage of the subjects showed low levels of serum zinc, it is suggested that the nutritional zinc status for the subjects was not satisfactory.

Postnatal cardiomyocytes have only limited capacity of proliferation. Therefore, the myocardium is intrinsically equipped with cardioprotective machineries and protects itself from pathological stresses. One of the most important cardioprotective systems is the signal network of autocrine/paracrine factors, including neurohumoral factors, growth factors, and cytokines. In this review, we focus on the roles of interleukin-6 (IL-6) family cytokines, also known as glycoprotein 130 (gp130) cytokines, in cardioprotection. These cytokines make a complex with their specific cytokine receptor α-subunits. The cytokine-receptor α-subunit complex binds to gp130, a common receptor of the IL-6 family, followed by the activation of JAK/STAT, ERK, and PI3 kinase/Akt pathways. In cardiomyocytes, signals through gp130 promote cell survival and angiogenesis through the JAK/STAT pathway. Activation of gp130 in cardiac stem cells induces their endothelial transdifferentiation, leading to neovascularization. Recently, accumulating evidence has revealed that altered JAK/STAT activity is associated with heart failure, suggesting that the JAK/STAT pathway is a therapeutic target against cardiovascular diseases. Interestingly, activation of the JAK/STAT pathway with interleukin-11 (IL-11) exhibits preconditioning effects in ischemia/reperfusion model. Moreover, IL-11 treatment after coronary ligation prevents cardiac remodeling through the JAK/STAT pathway. Since IL-11 is used for patients with thrombocytopenia, we propose that IL-11 is a candidate cytokine clinically available for cardioprotection therapy.

『北条五代記』「関東の乱波智略の事」に登場する容貌魁偉な風摩が率いた一党の性格如何の考察。先ず、原典を引用し、現代語訳文を付した。記事中の「悪盗」の語と、室町時代後期の辞典『節用集』の「悪党」の項から、風摩一党を悪党集団と推定したが、当時乱波と呼ばれた風摩一党を旧来の悪党の語で括るのは疑問である。そこで、検討を加えた結果、当時の乱波と透波は、同一・共通の実体を指し示す語であり、その実体とは悪党であったことなどを推定できた。風摩一党は、戦国大名後北条氏に扶持され、夜間奇襲攻撃中心のゲリラや間諜として、戦国末期社会に文字通り暗躍していたが、風摩一党の智略に関する挿話が、実は、『太平記』にそのまま出ている所から、旧来の悪党集団と本質的に異ならないことを指摘し、風摩一党が夜討に伴う分補・乱補等の略奪行為を本領とした点で、山賊・海賊・強盗と同様の略奪者集団であり、悪党に他ならなかったと結論した。
