In the present study, the preliminary results of a large-scale seismic response analysis of a super-high-rise steel frame considering soil-structure interaction are presented. A seismic response analysis under the excitation of the JR Takatori record of the 1995 Hyogoken-Nanbu earthquake is conducted. Precise meshes of a 31-story super-high-rise steel frame and a soil region, which are constructed completely of hexahedral elements, are generated and combined. The parallel large-scale simulation is performed using K computer, which is one of the fastest supercomputers in the world. The results are visualized using an offline rendering code implemented on K computer, and the feasibility of using a very fine mesh of solid elements is investigated. The computation performance of the analysis code on K computer is also presented.

Welfare vehicles are widely used for disabled or elders, however, it is difficult for users to pick up their package while they are in the vehicle. For these picking tasks, the automatic mobile robot with a robot arm has been used. The pointing of the package and its actions should be instructed at first. For disabled or elders, however, it is desirable to give instructions as simple as possible to operate the robot. Recently, Mixed Reality (MR) devices attract attention to support these tasks. Users will give instructions for the robot intuitively by using an HMD with MR. In this paper, an assist robot in which a robot arm automatically sucks the package is proposed by indicating the rough position using HMD. We have developed a system in which the user commands an assist robot to handle packages from a distance location using an HMD and an assist robot picks packages automatically using AR markers.

This paper considers the acceptance status and development process of ramen, one of the Chinese noodle dishes in modern Japan. After the country‘s opening, many Chinese people came to Japan, along with Westerners. Chinese people constitute more than half of the foreigners visiting Japan and developed Chinatown, where they run Chinese restaurants. Owing to the arrival of Chinese students in Japan and the relaxation of the settlement system, Chinese restaurants opened prolifically in addition to the settlement. Initially, Chinese food was unpopular, however, due to the increase in the working population due to industrialization, the promotion of pork, and publications on Chinese food, Chinese food was reviewed and became popular. When Japanese ramen shops opened, ramen changed to suit Japanese tastes. Ramen shops are cheap and delicious; thus, they will be accepted by the masses. Furthermore, it seems that the increase in the yield of wheat used for ramen noodles also contributed to the spread of ramen. Ramen shops and food stalls opened prolifically, and low-wage workers and students began to frequent them. Chinese cuisine was accepted with the encouragement of Western culture by the countrys opening. Furthermore, it was found that ramen, Chinese food dish, was changed to suit Japanese peoples tastes. Thus, it became popular naturally, both economically and tastefully, in line with the eating habits of the public.

Detailed finite element (FE) analyses of a full-scale four-story steel frame structure, subjected to consecutive 60% and 100% excitations from the JR Takatori records during the 1995 Hyogoken-Nanbu earthquake, are conducted using E-Simulator. The four-story frame was tested at the largest shake-table facility in the world, E-Defense, in 2007. E-Simulator is a parallel FE analysis software package developed to accurately simulate structural behavior up to collapse by using a fine mesh of solid elements. To reduce computational time in consecutive dynamic time history analyses, static analysis with gravity force is introduced to terminate the vibration of the structure during the analysis of 60% excitation. An overall sway mechanism when subjected to 60% excitation and a story mechanism resulting from local buckling of the first-story columns when subjected to 100% excitation are simulated by using E-Simulator. The story drift response to the consecutive 60% and 100% excitations is slightly smaller than that for the single 100% excitation.
TRANS-SUPPRESSION OF GENE EXPRESSION BY HEPATITIS C VIRAL CORE PROTEIN

We have demonstrated that the truncated hepatitis C(HCV) core protein with its C-terminal hydrophobic domains deleted is translocated to the nucleus of transfected cells (22). In this study, intact and truncated core proteins of HCV were transiently expressed in a human hepatoblastoma cell line, HepG2, and their effects on the expression of the chloramphenycol acethyl transferase (CAT) gene driven by viral and cellular promoters were examined. The intact core protein of 22kDa which is localized in the cytoplasm of the transfected cells suppressed the expression in all of the promoters tested. They were promoters of the SV40 early region, the c-fos oncogene, the retinoblastoma susceptibility gene, the β-interferon gene and the β-actin gene. In contrast, the truncated HCV core protein located in the nucleus did not shoe such a suppressive activity. The HCV core protein appears to function not only as a viral structural protein but as a regulator of gene expression and it might act as a suppressive factor for the cellular gene expression.
Soft-tissue coverage for wound complications following total elbow arthroplasty

Background: In patients with total elbow arthroplasty (TEA), the soft-tissue around the elbow can be vulnerable to soft-tissue complications. This study aims to assess the outcomes after soft-tissue reconstruction following TEA. Methods: We retrospectively included nine adult patients who underwent soft-tissue reconstruction following TEA. Demographic data and disease characteristics were collected through medical chart reviews. Additionally, we contacted all four patients that were alive at the time of the study by phone to assess any current elbow complications. Local tissue rearrangement was used for soft-tissue reconstruction in six patients, and a pedicle flap was used in three patients. The median follow-up period was 1.3 years (range, 6 months–14.7 years). Results: Seven patients (78%) underwent reoperation. Four patients (44%) had a reoperation for soft-tissue complications, including dehiscence or nonhealing of infected wounds. Five patients (56%) had a reoperation for implant-related complications, including three infections and two peri-prosthetic fractures. At the final follow-ups, six patients (67%) achieved successful wound healing and two patients had continued wound healing issues, while two patients had an antibiotic spacer in situ and one patient underwent an above-the-elbow amputation. Conclusions: This study reports a complication rate of 78% for soft-tissue reconstructions after TEA. Successful soft-tissue healing was achieved in 67% of patients, but at the cost of multiple surgeries. Early definitive soft-tissue reconstruction could prove to be preferable to minor interventions such as irrigation, debridement, and local tissue advancement, or smaller soft-tissue reconstructions using local tissue rearrangement or a pedicled flap at a later stage.

A 43-year-old man with rheumatic arthritis was admitted to our hospital for symptoms of cough, left chest pain, and leftelbow pain, and further examination revealed an elevated level of C-reactive protein. On day 2 after admission, he underwentesophagogastroduodenoscopy. On the morning of day 7, he developed a high fever of 39.7°C, several hours after bronchoscopy. Onday 13, he underwent colonoscopy. Five minutes after the colonoscopy, he developed a high fever of 39.9°C, accompanied by stridor,indicating a decrease in arterial oxygen saturation level. An intradermal test for peracetic acid which was used for cleaning flexibleendoscopy was positive. We suspect that he suffered from an allergic reaction to peracetic acid following the flexible endoscopy. This is the first case reported on suspicious allergic reaction to peracetic acid following a flexible endoscopy procedure.
