AO入試の何が変わり，何が変わらなかったか : 広島大学AO入試の10年 <ノート>

広島大学でAO入試を開始して10年、この間、導入当初の制度設計から変更した点もあれば、現在に至るまで変わらない点もある。大学入試センター試験を課す入試方式（AO入試Ⅱ型）への移行や入試期間の短縮等当初から変更した点は、より適切な入試制度として変更が求められたものであり、入試時期等当初からずっと変わらなかった点は、本学のAO入試制度として適切であったものと言える。このような観点からの入試制度の検証と入学者の学業成績の追跡調査等から、現時点での本学のAO入試の成果と課題をまとめる

ハワイ州における高大連携プログラム <ノート>

米国では、現在、初等教育から高等教育までのシームレスな接続をめざす「P-16（またはK-16, P-20）」と呼ばれる教育政策が多くの州において展開されている。広島県の公立高校と姉妹校締結を行っているハワイ州の高校における高大接続に関する調査の際に、P-20（ハワイ州）プログラムについて調査を行う機会を得た。米国全体における最近の状況とハワイ州における状況についてその特徴を分析し、我が国における高大連携及び高大接続への示唆を検討したい。本研究はJSPS科研費 23653268 の助成を受けたものである

External iliac venous aneurysm in a pregnant woman: a case report

AbstractWe report an external iliac venous aneurysm in a young pregnant woman who was diagnosed incidentally by ultrasound scanning. The aneurysm was successfully treated by tangential aneurysmectomy and lateral venorrhaphy. Primary iliac venous aneurysm is a rare vascular abnormality. The clinical significance of the disease is unknown. However, embolism, rupture, and thrombosis might occur as they can occur with popliteal venous aneurysm. In fact, three of four reported patients with iliac venous aneurysms had a thromboembolic event. For those reasons, prophylactic treatment is indicated. This is the first patient with an iliac venous aneurysm to be diagnosed without complication

Epidemiological Study of Lipoprotein (a) in Okinawa

A study of serum levels of lipoprotein (a) (Lp (a)) was performed among 217 normal adults including 135 men and 82 women in the northern part of Okinawa. Ages of the subjects ranged from 24 to 76 with an average of 49 years. Concentrations of Lp (a) in blood were measured by sandwich ELISA. The average Lp (a) concentration was 20.7 mg/ dl and the peak of the distribution of serum Lp (a) concentration ranged from 10 to 15 mg/dl. A greater number of people in the investigated area tended to show a higher level of serum concentration of Lp (a) than those in any other prefectures in Japan, although there was no significant relationship between serum level of lipoprotein (a), total cholesterol, triglyceride, age or gender in healthy subjects

Localization and Quantum Hall Effect in Two-Dimensional Systems Under Strong Magnetic Fields(Transport and Fermiology)

Experimental researches of quantum transport properties of semiconductor two-dimensional electron systems in Si-MOSFETs and GaAs/AlGaAs heterostructures in high magnetic fields up to 27 T and at low temperatures down to 20 mK are performed. Analysis of the Hall conductivity of Si-MOSFETs based on a mobility edge model shows that the temperature dependence of the mobility edge can not be explained by existing theory of localization. The fractional quantum Hall effect is observed at the filling factor of 1/7 in heterostructures. Sample size dependence and magnetic field dependence of the breakdown of the integral quantum Hall effect in heterostructures reveal that the Hall current is carried not by the edge states but by the extended states in the localization in the bulk of the two-dimensional systems

Long-term follow-up of endovascular coil embolization for cerebral aneurysms using three-dimensional time-of-flight magnetic resonance angiography.

OBJECTIVES: As endovascular treatment becomes more prevalent, aneurysm recurrence from neck remnants, recanalization, incomplete obliteration and bleeding remain major concerns. In the current analysis, we attempted to identify factors related to disease progression and clinical outcome in patients treated with coil embolization. METHODS: This study included 58 patients who underwent endovascular coil embolization for treatment of intracranial aneurysm. The result of embolization was evaluated with three-dimensional time-of-flight magnetic resonance angiography (TOF MRA) and classified as a complete occlusion, a residual neck (minor, central and marginal types), a residual dome (central and marginal types). Patients were followed up clinically and radiologically. Statistical analyses were performed to establish factors that influenced the occurrence of adverse events such as recurrence of aneurysm. RESULTS: Overall, the complete occlusion rate was 18.8%, the occurrence of a residual neck was 67.2%, and the residual dome rate was 14.1%. The mean clinical follow-up was 31.2 months. Recurrences were found in 18 aneurysms, and major recurrences were retreated with coiling or surgery. The post-treatment study revealed that the marginal-type aneurysm filling has a significant impact on outcome. Thus, perianeurysmal edema was correlated with recurrence of the aneurysm. CONCLUSIONS: Three-dimensional TOF MRA was a sensitive tool for visualizing residual filling of embolized aneurysm and is useful for long-term follow-up of patients

Recurrence of the cavernous sinus dural arteriovenous fistula at adjacent sinuses following repeated transvenous embolizations: case report and literature review.

We present a unique case of a cavernous sinus (CS) dural arteriovenous fistula (DAVF), which recurred at adjacent sinuses following repeated transvenous embolizations (TVEs). A 68-year-old woman presented with progressive left conjunctival chemosis and diplopia. Cerebral angiography revealed a left CS DAVF, which was completely obliterated by TVE via the left inferior petrosal sinus (IPS). Two years later, the DAVF recurred in the left IPS, and again in the left sigmoid sinus (SS) 3 years after the initial treatment in spite of a second TVE. Moreover, the left SS and the left internal jugular vein, which had been previously stenotic, had been occluded. The third TVE resulted in the complete obliteration of the SS DAVF. CS DAVFs may recur at adjacent sinuses even after complete obliteration by TVE. Careful follow-up is necessary to check for the recurrence of DAVFs, especially in cases with venous flow changes, such as sinus occlusion, following endovascular treatment.The original publication is available at www.springerlink.co
