I should like to express my sincere admiration for Arata lsozaki. One of the world’s leading architects, he has unveiled a constant succession of ambitious works. Being also from Kyushu, I have always felt a sense of kinship with Isozaki. It might be mentioned that the educational philosophy of modern Japan originated in Kyushu. Likewise, Japan’s most famous private universities are Waseda and Keio. Shigenobu Okuma, who came from what is now Saga Prefecture, founded the former, and the latter was established by Yukichi Fukuzawa, who hailed from what is today Oita Prefecture. As for architects

Objective: To determine if a subcutaneous closed suction drain decreases the incidence of wound complications in patients undergoing emergency surgery for colorectal perforation. Materials and Methods: Data on 47 patients who underwent emergency operations for colorectal perforation were examined retrospectively. The clinical features of these cases with or without the use of the J-VACTM Drainage System were examined, and statistical analysis was performed. Results: In these high-risk cases, the overall incidence of incisional surgical site infection (SSI) was 36.2%. The incidence of incisional SSI in these cases with and without the J-VACTM Drainage System was 16.7% and 56.5%, respectively. Conclusion: Our results suggest that a subcutaneous closed suction drain is effective for preventing incisional SSI in patients who have undergone emergency operations for colorectal perforation.

Although acute appendicitis is a common disease, retroperitoneal abscesses are rarely observed. Here, we report a case consisting of a psoas abscess and cutaneous fistula caused by appendicitis. The patient was a 56-year-old male who was introduced to our institution due to an intractable right psoas abscess. Imaging tests had been performed over the previous 3 years; however, clinicians could not find the origin of the abscess and failed to resolve the problem. A successful operation was performed via a laparoscopic approach, and 17 mo have passed without recurrence. The advantage of laparoscopic surgery is well understood in cases of appendicitis with abscesses. However, the indication for laparoscopic approach is not clear for retroperitoneal abscesses. From our experience, we can conclude that appendicitis with retroperitonealabscesses can be managed and treated using a laparoscopic approach.

Black-colored titanium was obtained by anodic oxidation of a commercially pure grade-1 titanium sheet in a 0.06 M NH4NO3 solution, followed by heat treatment at 773 K for 1 h in a vacuum furnace. The resulting oxide layer on the titanium substrate was examined by X-ray photoelectron spectroscopy, X-ray diffraction, glow discharge spectroscopy, and scanning electron microscopy. It was found that the oxide layer on the black-colored titanium sheet was several micrometers thick and mainly consisted of rutile TiO2 exhibiting a sponge like nanoporous structure. It is considered that the black-colored appearance of the titanium sheet is due to the sponge like nanoporous structure of the oxide layer absorbing the incident light. The photocatalytic activity of the black-colored titanium sheet was examined by observing the decomposition of a methylene blue (MB, C16H18N3SCl) solution under ultraviolet irradiation due to the existence of rutile TiO2. The sheet also exhibited photocatalytic activity under visible light irradiation. It is believed that the photocatalytic response upon irradiation with white light is due to carbon doping of the titanium oxide layer on the titanium substrate.

A commercially pure titanium sheet precipitated TiC in the surface layer was fabricated by anodic oxidation in NH4NO3 solution and heat treatment in air. The fabricated sheet showed relatively high photocatalytic activity in 0.1 M KI solution, which was close to the activity level of the P-25 particle made by Degussa Corporation. It exhibited photocatalytic activity in antifungal and antivirus tests under black light irradiation. The better photocatalytic activity under black light irradiation is considered to be related to the formation of anatase and rutile type titanium dioxides and rough surface. It also showed photocatalytic activity under visible light irradiation, which is considered to be attributable to carbon and nitrogen doping in titanium dioxide.

A commercially pure titanium sheet with titanium carbide (TiC) precipitated in its surface layer was anodized in NH4NO3 aqueous solution and heat treated in air. The photocatalytic activity of titanium dioxide powder collected from the surface of the anodized titanium sheet was evaluated under ultra-violet and visible light irradiation. It showed relatively high photocatalytic activity in 0.1 mol/l potassium iodide solution, which was almost equal to the activity level of TiO2 powder (P-25) manufactured by Degussa Corporation. The better photocatalytic activity under ultra-violet irradiation is considered to be related to the formation of anatase type titanium dioxide. Photocatalytic activity under visible light irradiation was also observed, which was considered to be attributable to impurity doping, (carbon), in the titanium dioxide powder.
