A 52-year-old man was admitted after sustaining a gunshot wound to the head. The patient had been ambulant at the time of impact but collapsed suddenly and was comatose upon admission. Brain computed tomography (CT) scans revealed an acute subdural hematoma with marked midline shift; an emergency evacuation of the hematoma and craniectomy were performed. He recovered neurologically and underwent cranioplasty using autologous bone two weeks after the initial surgery, but he developed a wound infection and subdural empyema, necessitating another debridement surgery. Cranioplasty using a ceramic bone was performed two months after the debridement, and he was discharged with no neurological deficits. Gunshot wounds to the head have a higher rate of postoperative infection than closed head injuries; thus, debridement to remove as much bony and missile fragments as possible is important.

The brightness of a room interior can be roughly determined from its luminance. However, the luminance of a room interior is not even, but rather is an amalgam of high-luminance areas and low-luminance areas. In this research we intended to determine the effect of luminance distribution on brightness. First, we conducted a experiment to estimate the brightness of stimuli that are of the different luminance distribution. Next, a experiment that examined the relationship between the characteristics of luminance variations and brightness in interior environment was conducted. As a result, the brightness in a room interior depended not just on luminance of visual field but also on the distribution of field luminance, and that although luminance distribution that originates in the varying reflectance of walls and floors does not affect brightness to a great extent, the luminance distribution resulting from non-uniform lighting caused an interior to seem darker.

We carried out questionnaires to make clear actual situations how the office workers took for a change (to refresh themselves). 95.4% of office workers regarded a refreshment as a requirement, and 83.7% had actually refreshed themselves in the office. Especially people thought that refreshing gave a clue to the solution. Many workers took a break for a refreshment at their desks or in washrooms, with drinking, chattering and looking out of the windows for 10 minutes or less. They thought that a window was important in the room for a refreshment. A lot of valuable information to design rooms for a refreshment was obtained.

Jyodoji-Jyododo is one of the religious architectures that express the nobility of the Land of Happiness making use of daylight. The mechanism how the daylight reaches a statue of Amitabha-Tathagata in Jyodoji-Jyododo, it has peculiar luminous environment that no other historic architectures have, has not proved yet. Then, for the purpose of proving the mechanism of daylight that influence a statue of Amitabha-Tathagata, we conducted following 3 simulations; 1) Inter-reflection simulation with Jyodoji-Jyododo architectural model and simplified Amitabha-Tathagata model to obtain distribution of illuminance. 2) Specular reflection simulation for identifying the parts of the architecture which principally contribute to glitter of the statue. 3) Simulation of changing the angle of ceiling to make clear the relationship of the phenomenon and the architecture. From the results, we found that the daylight from the back of a statue of Amitabha-Tathagata repeats diffuse reflection, and a statue of Amitabha-Tathagata is shined by the daylight gathered at the ceiling. And the reason of a steeply slanting roof is infered that the daylight is took in a statue of Amitabha-Tathagata.

Studies have previously been undertaken on the prediction of perceived spatial brightness aimed at achieving designs that take account of a feeling of brightness of space, and various estimation models and factors affecting the prediction of perceived spatial brightness are known. In this study the authors focused their attention primarily on factors other than average brightness to explain perceived spatial brightness in nonuniform luminance distribution with the aim of proposing an index which encompasses existing knowledge while being based on simple quantities. The authors set 32 different lighting conditions in an office with north-facing windows and measured the luminance images for each condition. They then asked subjects to evaluate the perceived brightness from two seats, one with the windows in sight and with no windows in sight, thereby providing 64 different luminance distribution and estimation value samples. Ten contrast images of different spatial frequency were decomposed from each luminance image by wavelet transformation symlet6, then AD (ambient directivity, low spatial frequency) and CD (contrast detail, high spatial frequency) were defined on the basis of each variance of contrast image. The authors used multiple regression analysis to obtain a multiple regression equation to explain spatial brightness using three variables: average luminance, or NB value; AD; and CD. AD lowers spatial brightness, while CD raises it. The estimated accuracy was greater than that achieved using a conventional equation. After considering the above, the authors suggested NSB (Natural scale of Spatial Brightness), a spatial brightness prediction model based on luminance contrast.

The aim of this article is to discuss the effectiveness of clockwise rotation of the occlusal plane for skeletal class III deformities with the use of two-jaw surgery.The most popular orthognathic surgical management for class III malocclusion is mandibular setback using a bilateral sagittal splitting ramus osteotomy (SSRO). However, it has been suggested that, with the aid of an operative method using SSRO alone, complete elimination of the protruded appearance in the mental region is hardly attainable, in some cases. To obtain better functional and esthetic results for patients with class M deformities, clockwise rotation of the occlusal plane, using two-jaw surgery, appears to be considerably useful surgical management. The changes provided by an increased occlusal plane angle include 1) advancement of the midface; 2) rotation of the chin posteriorly; 3) a decreased maxillary incisor angle; 4) an increased mandibular plane angle; 5) decreased posterior facial height. We emphasize that, by appropriate usage of clockwiserotation of the occlusal plane, more favorable functional and esthetic results for the correction of skeletal class deformity will be enabled in some cases.

夜間商店街の視環境は、街路灯や看板灯、ウィンドゥディスプレイの光など多様な照明要素で構成されているが、これらの光環境は一般的に20時前後を境にして急激に変容する。これは店舗が閉店すると同時に付随する看板灯や内部照明を全て消灯してしまうからである。看板灯や店舗からの漏れ光は、屋内の人間活動と結びついていることから、こうした光は外部に対して単に視覚的な明るさを与えるだけでなく、人の気配を感じさせる働きがあるのではないかと考えられる。本研究は、店舗に付随する照明要素の心理的な働きを理解することによって、閉店後における街路の環境を改善する手がかりを得ようとしている。はじめに、開店時から閉店時にかけて商店街光環境の移り変わりを体験させ、その印象を把握する実験を行った。その結果、閉店後の光環境は全般的に不安で監視性が低く、監視性の低さは店舗から漏れ出す光が強く関与していることがわかった。そこで次に、店舗から漏れ出す光量やファサードの透視性を変数とした評価実験を行ったところ、路上で感じられる人の気配や安心感は、漏れ光の強さだけでなく、店舗ファサードの形態と関わりがあることがわかった。

The accuracy of positioning the osteotomized maxilla during orthognathic surgery was assessed in 26 patients, comparing the use of an external reference point placed on the forehead skin (SERP), and an external reference point consisting of a bone screw placed at the forehead bone (BERP). In all cases, the unoperated mandible was used to provide an anteroposterior and transverse maxillary position, through use of an intermediate splint. In 14 cases, the distance between the SERP and the maxillary central incisor was measured, to determine the maxillary vertical dimensions. In 12 cases, measurements between the BERP the and maxillary central incisor were made.<BR>All preoperative lateral cephalometric radiographs were traced by one investigator, and these tracings were superimposed on postoperative lateral chephalograms (3 to 6 days after surgery), respectively. The actual changes in the vertical and horizontal position of U1 were measured perpendicular and parallel to the Frankfort horizontal plane. The actual change of the palatal plane angle was also measured. These values of actual change were compared with the prediction tracings made by measurements obtained from model surgery, and the difference between planned and actual movements was calculated.<BR>The mean difference of U1 anteroposterior movement was 1.5±2.0mm in the SERP group, and 1.2±1.1 mm in the BERP group. The mean difference of U1 vertical movement was 1.8 ±2.8mm in the SERP group, and 0.5±0.3mm in the BERP group. And the mean difference of palatal plane angle rotation in the SERP group was 2.7±6.2°, and 1.6±1.8° in the BERP group. Statistical analysis showed a significant difference between the SERP group and the BERP group in the U1 vertical difference (t-test, p<0.05).<BR>The results of this investigation revealed less accuracy in the actual three-dimensional maxillary movements of the SERP group, compared with the BERP group. And this study also showed that use of the BERP will allow accurate three-dimensional control of the maxillary position, especially in the vertical dimension. However, the maxillary repositioning technique using BERP still remains subject to operator error, and other numerous possible sources of error were identified, which may lead to an incorrect result.

歯を移動した際の歯根膜の遺伝子発現について検討することを目的とした。そこで、歯の移動の初期変化として歯の移動6時間と、大きな組織変化の起っている歯の移動5日間の歯根膜に着目し、遺伝子の解析を行なった(コントロールとして歯を移動していない歯根膜を使用した。ラット上顎第一臼歯の歯の移動を6時間と5日間行い、第1臼歯の凍結非脱灰切片を作製し、laser microdissection法により歯根膜採取し、DNAマイクロチップを用いて発現遺伝子の解析を行い、前年度の正常下での歯根膜の発現遺伝子のデーターと比較検討した。なお、比較検討は正常下での歯根膜の発現遺伝子より2倍以上強く発現しているものと1/2以下のものをリストアップして行なった。歯の移動6時間の結果では、全遺伝子44284中、圧迫側ではその発現が2倍以上増加したものは2960個、1/2以下に減少したもの2978個であった。牽引側では2倍以上のもの2506個、1/2以下に減少したもの2722であった。また、歯の移動5日の結果では。全遺伝子44284中、圧迫側ではその発現が2倍以上増加したものは4239個、1/2以下に減少したもの2849個であった。牽引側では2倍以上のもの3762個、1/2以下に減少したもの2722個であった。歯の移動においては歯根膜の細胞が歯根膜の圧縮や拡張に対して、その細胞内で発現遺伝子を変化させて、新しい環境に適応しているものと思われた。特に牽引側では骨形成に関する遺伝子群、圧迫側ではアポトーシスや骨吸収に関する遺伝子群でその発現量が顕著に増加していた。
