Various techniques for creating a comfortable thermal environment and saving energy have been proposed and employed in residential buildings in many countries, including Japan. For these techniques to be introduced, existing houses should be renovated. Among the techniques available, installation of additional inner windows is effective in creating a comfortable and energy-efficient living environment. In the present research, the effect of additional inner windows on the thermal environment and energy saving was investigated by measuring indoor climates. Windows were renovated in two rooms on the fourth floor of a four-story reinforced concrete building. Air temperatures, the humidity, the global solar radiation on horizontal and vertical surfaces, radiant temperatures, and the electricity consumption of air-conditioners were measured. A comparison of these vatues before and after the installation of inner- windows showed that the thermal environment and energy saving had improved. Results obtained from a thermal model agreed well with measured results by changing the value of solar transmittance and heat transmission coefficient of the glazing forlowing renovation. Furthermore, in a questionnaire survey conducted in summer, more than half of the occupants answered ＂cornfortabte＂ to a question on the overall thermal comfort.

In this study, we propose a holographic augmented reality (AR) display with a wide viewing zone realized by using a special-designed reflective optical element. A conical holographic optical element (HOE) is used as such a reflective optical element. This conical HOE was implemented to reconstruct a diverging spherical wave with a wide spread angle. It has a sharp wavelength selectivity by recording it as a volume hologram, enabling augmented reality (AR) representation of real and virtual 3D objects. The quality of the generated spherical wave and the spectral reflectivity of the fabricated conical HOE were investigated. An optical superimposition between real and virtual 3D objects was demonstrated, thereby enhancing the validity of our proposed method. A horizontal viewing zone of 140° and a vertical viewing zone of 30° were experimentally confirmed. The fabrication procedure for the conical HOE is presented, and the calculation method of the computer-generated hologram (CGH) based on Fermat’s principle is explained in detail.

Objective: The aim of the study is to evaluate the long-term changes in fatigue of cancer patients receiving outpatient chemotherapy after a disaster such as the Great Earthquake. Methods: From 2012 to 2014, we measured subjective fatigue, autonomic function, and physical activity with reference to the criteria for chronic fatigue syndrome. Results: The participants were 13, 9 males (69.2%) and 4 females (30.8%). The most common cancer among the participants was lung cancer 4 patients (30.8%). In 2012, eight patients (61.6%) received anti-cancer drugs and three (23.0%) received the drug by intravenous drip and oral administration. Physical fatigue (p = 0.004), mental fatigue (p = 0.002), comprehensive fatigue (p = 0.012), and comprehensive evaluations (p = 0.032) were significantly different. Significant differences in the autonomic nervous function were observed during the three years from 2012 to 2014 (log LF [p = 0.017], log HF [p = 0.023] and log LF/HF [p = 0.039]). Similar to Subjective fatigue, Significant differences in physical activity were observed during the three years from 2012 to 2014 (DA [p = 0.042], TST [p = 0.037], SE [p = 0.018], AW [p = 0.023] and Naps [p = 0.014]). Conclusions: The participants fatigue worsened at one time, but showed improvement over time. In the event of an emergency such as a disaster, it is necessary to evaluate the physical and mental condition based on objective indicators of cancer patients receiving anti-cancer drug treatment and provide nursing support.

AIM： To study the therapeutic effect of interferon （IFN） and ribavirin with zinc supplement on patients with chronic hepatitis C viral （HCV） infection. METHODS： A total of 102 patients confirmed histologically to have chronic HCV infection with genotype lb and more than 100 KIU/mL of HCV were randomly assigned to each arm of the study and each received 10 million units of pegylated interferon （IFN- alpha-2b） daily for 4 wk followed by the same dose every other day for 20 wk plus ribavirin （600 or 800 mg/d depending on body weight）, with or without polaprezinc （150 mg/d） orally for 24 wk. The primary endpoint was sustained virological response （SVR） defined as negative HCV-RNA in the serum 6 mo after treatment. RESULTS： There were no differences in the clinical background between the two groups except for more females in the dual therapy group than in the other group （P〈 0.05）. SVR was observed in 33.3% of the triple therapy group and 33.3% of the dual therapy group. The side effects were almost the same in both groups except for gastrointestinal symptoms, which were less in the triple therapy group （P= 0.019）. CONCLUSION： Considered together, triple therapy of zinc plus IFN and ribavirin for HCV infection patients with genotype lb and high viral load is not better than dual therapy except for lower incidence of gastrointestinal side effects.

Background:Pancreaticoduodenectomy(PD)is a standardized strategy for patients with middle and distal bile duct *** aim of this study was to compare clinicopathological features of bile duct segmen-tal resection(BDR)with PD in patients with extrahepatic ***:Consecutive cases with extrahepatic cholangiocarcinoma who underwent BDR(n=21)or PD(n=84)with achievement of R0 or R1 resection in Kobe University Hospital between January 2000 and December 2016 were enrolled in the present ***:Patients who underwent PD were significantly younger than those receiving *** frequency of preoperative jaundice,biliary drainage and cholangitis was not significantly different between the two *** duration of surgery was longer and there was more intraoperative bleeding in the PD than in the BDR group(553 vs.421 min,and 770 vs.402 mL;both PClavien-DindoⅢa)were observed in the PD group(46%vs.10%,P<0.01).Postoperative hospital stay was also longer in that group(30 vs.19 days,P=0.02).Pathological assessment revealed that tumors were less advanced in the BDR group but the rate of lymph node metastasis was similar in both groups(33%in BDR and 48%in PD,P=0.24).The rate of R0 resection was significantly higher in the PD group(80%vs.38%,P<0.01).Adjuvant chemotherapy was more frequently administered to patients in the BDR group(62%vs.38%,P=0.04).Although 5-year overall survival rates were similar in both groups(44%for BDR and 51%for PD,P=0.72),in patients with T1 and T2,the BDR group tended to have poorer prognosis(44%vs.68%at 5-year,P=0.09).Conclusions:BDR was comparable in prognosis to PD in middle bile duct *** invasiveness and lower morbidity of BDR justified this technique for selected patients in a poor general condition.

Hemolymphangioma of the pancreas is a very rare benign tumor. There were only five reports of this disease until March 2008. Herein, we report a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to duodenal invasion. A 53-year-old man had been admitted a referral hospital because of severe anemia due to gastrointestinal bleeding in December 2005. He was then transferred to our institute with a diagnosis of a tumor of the head of the pancreas with duodenal invasion in January 2006. No abnormalities were revealed except for anemia in laboratory data including CEA and CA19-9. Gastrointestinal endoscopy revealed bleeding at the duodenum. Computed tomography also demonstrated a heterogenous mass at the pancreatic head and suspected invasion to the duodenal wall. Ultrasonography showed a huge mass at the pancreatic head with a mixture of high and low echoic areas. Pylorous-preserving pancreatoduodenectomy was performed. The pancreatic tumor was soft and had invaded to the duodenum. The pathological diagnosis was a hemolymphangioma of the pancreas invaded to the duodenum. His postoperative course was uneventful and he was discharged on the 26th d after surgery. Hemolymphangioma of the pancreas is a very rare benign tumor. In a literature review until March 2008, we found five case reports. Major symptoms are abdominal pain and distension due to the enlarged tumor. However, we experienced a case of hemolymphangioma of the pancreas with gastrointestinal bleeding due to invasion to the duodenum. This disease is a very rare entity, but should be considered when patients have gastrointestinal bleeding.
