Effects of Calcination Temperature on the Phase Composition, Photocatalytic Degradation, and Virucidal Activities of TiO Nanoparticles.

The application of TiO nanoparticles in the photocatalytic treatment of chemically or biologically contaminated water is an attractive, albeit unoptimized, method for environmental remediation. Here, TiO nanoparticles with mixed brookite/rutile phases were synthesized and calcined at 300-1100 °C to investigate trends in photocatalytic performance. The crystallinity, crystallite size, and particle size of the calcined materials increased with calcination temperature, while the specific surface area declined significantly.

Alkaline Hydrolysis and Dyeing Characteristics of Sea-Island-Type Ultramicrofibers of PET Tricot Fabrics with Black Disperse Dye.

In this study, we investigated conditions for the alkaline hydrolysis and black-disperse dyeing of sea-island-type polyethylene terephthalate (PET) ultramicrofiber tricot fabric. We examined the weight loss ratios and tensile strengths according to the NaOH content (10%-30% on mass of fabric (omf)) during treatment; the optimal conditions used 25% omf NaOH for 30 min at 100 °C for an average weight loss ratio of 23.47%.

Lane-Level Map-Matching Method for Vehicle Localization Using GPS and Camera on a High-Definition Map.

Accurate vehicle localization is important for autonomous driving and advanced driver assistance systems. Existing precise localization systems based on the global navigation satellite system cannot always provide lane-level accuracy even in open-sky environments. Map-based localization using high-definition (HD) maps is an interesting method for achieving greater accuracy.

An Enhanced Map-Matching Algorithm for Real-Time Position Accuracy Improvement with a Low-Cost GPS Receiver.

This paper proposes a real-time position accuracy improvement method for a low-cost global positioning system (GPS), which uses geographic data for forming a digital road database in the digital map information. We link the vehicle's location to the position on the digital map using the map-matching algorithm to improve the position accuracy. In the proposed method, we can distinguish the vehicle direction on the road and enhance the horizontal accuracy using the geographic data composed of the vector point set of the digital map.

Effects of statins on the recovery of olfactory function in a 3-methylindole-induced anosmia mouse model.

Background: Despite the importance of olfactory function, no effective medications have been identified to treat olfactory disorders. This study was performed to evaluate the functional recovery of olfaction damaged by 3-methylindole (3MI) in a mouse model with hydroxymethylglutaryl-coenzyme A reductase inhibitors (statins).

Methods: In a randomized placebo-controlled trial, 24 healthy female BALB/c mice (aged 9-10 weeks and weighing 18-20 g each) were randomly allocated to statin-treated or control groups.

Modified mattress suturing technique for correcting the septal high dorsal deviation around the keystone area.

Background: High dorsal deflection of the nasal septum around the bony-cartilaginous junction ("keystone area") is often missed and difficult to treat because of the importance of septal support. This study introduces a new technique of septoplasty to correct this dorsal deviation.

Methods: Forty-two patients with severe dorsal septal deviation around the bony-cartilaginous junction were included in the study.

[Two cases of multiple adenomas in the ileal pouch after total proctocolectomy in patients with familial adenomatous polyposis].

Familial adenomatous polyposis (FAP) is an inherited disease characterized by the development of hundreds of colorectal adenomas, leading to a 100% lifetime risk of colorectal cancer. A prophylactic colectomy is recommended for patients with FAP to prevent colorectal cancer. Four surgical strategies are available for patients with FAP: proctocolectomy with permanent ileostomy, colectomy with ileorectal anastomosis, proctocolectomy with Kochs pouch continent ileostomy (Koch), and restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA).

Fibroma of the tympanic membrane.

A primary tumor of the tympanic membrane is very rare. Herein, we describe a patient with a thick tympanic membrane that caused progressive hearing loss. The patient was treated with total resection of the tympanic membrane and was diagnosed with fibroma after histopathologic examination.

Functional benefit after modification of radial forearm free flap for soft palate reconstruction.

Objectives: To compare the velopharyngeal function, swallowing and speech of the conventional and modified radial forearm free flap (RFFF) for soft palate reconstruction.

Methods: Retrospective clinical study. Twenty-eight patients who underwent oropharyngeal reconstruction with RFFF were divided into two groups: 10 patients had conventional folded RFFF and 18 patients underwent modified method.

Nonleukemic granulocytic sarcoma in the bile duct: a case report.

Granulocytic sarcoma (GS) is an extramedullary tumor composed of immature myeloid cells, typically occurring during the course of acute myelogenous leukemia. Non-leukemic GS, that is, GS with no evidence of overt leukemia and no previous history of leukemia, is very rare, and even more unusual is nonleukemic GS of the bile duct. We report a case of nonleukemic GS of the bile duct.

[Clinical features of fulminant hepatic failure in a tertiary hospital with a liver transplant center in Korea].

Background/aims: Striking geographic differences have been noted in the etiology of fulminant hepatic failure (FHF). The prognosis of patients with FHF who do not receive liver transplantation in a timely manner is quite dismal. This study intended to identify the etiology and outcome of FHF in Korean adults and to examine the role of urgent living-donor liver transplantation (LDLT) for treating this unique situation.

Systemic inflammatory syndrome and hepatic inflammatory cell infiltration caused by an interleukin-6 producing pheochromocytoma.

Pheochromocytoma is a tumor that produces a variety of biologically active substances in addition to catecholamines. We report here a patient with a pheochromocytoma, who presented with acute inflammatory symptoms and marked abnormalities in liver function and hematological tests. A 31-year-old man, who had experienced intermittent fever, chills and weight loss during the previous several months, was referred to our hospital for further evaluation.
