Evaluation of jawbone quality is very important for successful implant treatment; however, a method to evaluate bone quality of the jaw has not been established. Furthermore, at present, bone classifications are relatively rough and subjective methods for pre-operative assessment. This study compared the buccal and the lingual cortical bone mineral densities (BMD), and correlation trabecular BNID and cortical BMD by quantitative computed tomography (QCT). The subjects were 56 patients with mandibular distal extension defect (20 males, 17 pre-menopausal and 19 post-menopausal women;age range 30 to 79 years). The buccal and lingual cortical BMD and the trabecular BMD were measured by QCT. The difference and the correlation among the three groups were estimated. The results were as follows. 1. The buccal cortical BMD was significantly higher than the lingual cortical BMD in the male and pre-menopausal group. However, no significant difference was seen between the buccal and the lingual cortical BMD in the post-menopausal group. 2. The buccal cortical BMD correlated well with the trabecular BMD in the male group. 3. The buccal and the lingual cortical BMD did not correlate with the trabecular BMD in the pre-menopausal group. 4. The buccal cortical BMD correlated significantly with the trabecular BMD in the post-menopausal group. In conclusion, it is important to consider these tendencies of mandibular BMD in dental implant treatment.

Globular titanium with a diameter of 212~250 μm was prepared using the rotating electrode method. It was then sintered under vacuum conditions to produce solid titanium material, to make the implant. We investigated the titanium implant material by evaluating the bond strength of the titanium particles to the titanium implant, the void area between titanium particles, the polarization resistance of titanium particles to the globular titanium implant, and alternating-current (AC) impedance properties. The following findings were obtained. 1. A shear force of about 5N was shown between the globular titanium implant and the titanium particles, although measurement was difficult. 2. The void area between globular titanium particles with a diameter of 212~250 μm ranged from 1.84×10-3 mm2 to 2.56×10-3mm2. 3. The Ecorr range of the titanium and globular titanium implant in 0.9% NaCl and artificial saliva aolution was -201~ -347 mV, and Icorr was 0.04×10-5~1.3×10-5mA/cm2. For titanium particles, Ecorr was -346 mV, and Icorr was 1.04×10-5mA/cm2. 4. The alternating current impedance measurement demonstrated increased corrosion resistance of the titanium material and globular titanium implant, which formed a passive oxide film in 0.9% NaCl and artificial saliva.

It has been demonstrated the involvement of branched-chain amino acids (BCAA) on obesity and related metabolic disorder. We investigated the effects of branched-chain amino acids (BCAA) on obesity and on glucose/fat homeostasis in mice fed on a high-fat (45%) diet. BCAA was dissolved in 0.5% methylcellulose and added to the drinking water (BCAA-treated group). A high-fat diet was provided for 6 weeks and BCAA was given for 2 weeks. The BCAA-treated group gained almost 7% less body weight and had less epididymal adipose tissue (WAT) mass than the control group (ppp<0.05). These results demonstrate that the liver and muscle TG concentration are less in BCAA-treated group. BCAA affects PPAR-alpha and UCP expression in muscle and liver tissue.

歯科医学および歯科治療学においてEBM(Evidence Based Medicine) あるいはEBD(Evidence Based Dentistry) の概念が提唱されて久しい.1965年に歯周病が歯肉辺縁部歯面に付着したプラークであることがヒトにおける実験的歯肉炎によって証明されて以来,歯周病学および歯周治療学について様々な科学的データが蓄積され,それに伴い歯周治療は急速な発展を遂げた.まず,1970年代に,プラークコントロールを基本とする歯周治療の科学的な根拠が提示され,歯周基本治療および歯周外科を中心とする修正期歯周治療の内容が確立された.それに続き1980年代から2000年にかけて,GTR法およびエナメルマトリクス蛋白の応用などの歯周組織再生療法が開発され,世界各国の研究機関でその有用性について検証が行われた後,多くの国で臨床応用に至っている.また,歯周組織の長期的な安定を保つには,歯科補綴的な介入が不可欠であり,その科学的な根拠も示されている.ここでは,現在一般的に行われている歯周治療の科学的な根拠を提示すると共に,それらの歯周治療の実践によって長期的保存の予知性が低い歯でも保存可能であったことを報告した論文を提示する.

本研究では都市のコンパクト化の評価指標として財政面と環境面に着目し、地域の現状をできるだけ反映した推計モデルの構築を行なった。また、宇都宮市を対象として分析を行なった結果、コンパクト化は財政面、環境面の双方において有利に働くことが確認された。特に、都市構造の変化の影響を受けやすい財政面における効果は大きいことが分かった。しかし、従来から効果が期待されていた環境面については、財政面ほどの効果が発現していない。これは交通分野の低炭素化は、都市のコンパクト化だけでは困難であることを示しているといえる。地方都市の交通部門のCO2排出量の大半は自動車交通であり、自動車交通の総トリップ長の減少がそのカギを握っている。個人の交通行動がより環境にやさしいモードへシフトするような施策の実施や、通過交通量の多い道路の道路円滑化など、総合的かつ広域的な施策が不可欠である

人が金色と認識している対象物は,物理的な測色結果によると黄色である.我々は,形状認識が金色認識の前提条件であるとの仮説を提示し,これを支持する実験結果を既に示している.本報告では,金色対象物表面における周囲環境の映り込みに着目した.我々は鏡面状の対象物表面への映り込みが対象物の形状認識を容易にし,結果的に金色認識に寄与すると想定し,これを検証するための実験を行なった.照明条件の調整により映り込みの無い状態と有る状態で金メッキスプーンを撮影し,撮影した画像中の対象物の形状と色を被験者に評価させた.金色認識の主観評価結果は,映り込みの無い画像では金色認識が困難になることを示した.同時に,形状認識の主観評価結果は,映り込みの無い画像では形状認識が難しくなることを示した.これらの結果から,対象物表面への周囲物映り込みは対象物の形状認識を容易にし,結果的に金色認識を容易にすると結論づけた.

In 1999, the authors organized a medical liaison group composed of dentists and a psychiatrist at the outpatient clinic of the Department of First Oral Surgery, Hospital of the School of Dentistry, Aichi Gakuin University, for the diagnosis and treatment of oral psychosomatic disorders. The practice has been for the dentists of the medical liaison group to examine each patient and diagnose his/her oral somatic disorder in the first stage of the examination, and the psychiatrist to examine each patient and make diagnosis according to DSM-IV or DSM-IV TR in the second stage.The subjects of this study were 13 patients with personality disorders (PD) among 268 patients examined during a 5-year and 4-month period from 2000 to 2004. The diagnoses by the dentists consisted of five cases of atypical facial pain, three of burning mouth syndrome, two of oral malaise, one of dental phobia, one of temporomandibular joint disorder, and one of halitophobia. Those by the psychiatrist consisted of six cases of pain disorder, two of conversion disorder, two of somatization disorder, one of hypochondriasis, one of specific phobia, and one of adjustment disorder. On DSM-IV Axis II, the diagnosis/suspicion results consisted of three cases of paranoid PD, two of avoidant PD, two of obsessive-compulsive PD, two of borderline PD, two of narcissistic PD, one of histrionic PD, and one of dependent PD. It was very difficult for us to manage the patients with borderline PD and narcissistic PD in cases of invasive treatment such as a tooth extraction. It has been found that the comorbidity of not only mental disorders but also personality disorders does need to be diagnosed and dentists ought to plan their therapeutic strategy for patients with personality disorders under the supervision of psychiatrists

[Purpose] The main purpose of our study was the evaluation of the effects of long-term volleyball practice on knee joint proprioception and balance of young female athletes. [Subjects and Methods] An observational case-control study was performed. The study enrolled 19 female volleyball players in the experimental group and 19 sedentary counterparts as controls. A Biodex balance system and dynamometer were used for the evaluations. The paired t-test was used to determine the significance of differences between the performance of athletes and controls. [Results] The knee proprioception analysis showed a significant difference at 60° joint position in active and passive tests. A similar trend, but without significance, was found for the 20° joint position. In the postural stability tests both groups showed similar results with no significant differences between them. [Conclusion] In conclusion, the results indicate a significant influence on joint proprioception is elicited by long-term exposure to a team sport like volleyball. However, the postural stability indexes showed similar trends in both groups, highlighting the analogous ontogenesis of the subjects investigated and the low influence of volleyball practice on postural stability.

Personality disorders (PD) include biases of cognition about the self or others in the general diagnostic criteria. Although the relationships between PDs and self-esteem have been clarified, the relationships of PD traits and evaluation affect about others have not been studied. This study examined relationships of PD traits and assumed competence in 304 undergraduates and graduate students. The results showed that individuals with the assumed type of competence had higher scores for borderline and obsessive-compulsive PD traits than other PD traits. The results suggest that maladaptive personality traits involve not only negative self-cognitions but also negative cognitions about others.

Employees at nursing-care facilities co-operate with each other and provide nursing-care service according to care plans designed to meet residents’ physical condition and needs. Traditionally, improvement of service productivity in nursing-care service has been based on experience and inspiration of managers and employees. Engineering methods to achieve improvement is a relatively new and necessary approach. In this paper, the authors collaborated with eight nursing-care facilities, and developed engineering methods to achieve improvement of their service process and service productivity. At first, we classified employees’ behaviors into a three-layer structure consisting of “service type”, “purpose / situation” and “operation”, and developed task classification for nursing-care service which could express 455 employees’ states. We then described nursing-care service process as transition of employees’ state with eight properties; “id”, “start time”, “end time”, “task”, “place”, “target resident”, “cost” and “detailed information”. Finally, we measured behaviors of 20 employees at four nursing-care facilities to evaluate the task classification for nursing-care service proposed in this paper, and confirmed that it covered 96.9 % of their behaviors. The cover rate was enough high for visualization of nursing-care service process. In addition, we visualized the nursing-care service process of 15 employees at a nursing-care facility with “time-line mode” and “statistical mode”. We also confirmed that our proposed methods were effective to visualize the nursing-care service process and to improve service productivity in the service field.

地理情報システム(GIS)は災害対応の際に有効なツールであるが、災害対応者自らがGIS を活用するために備えるべき要件について検討した研究はこれまで無かった。そこで本研究では、災害対応者が自らGISを利用して効果的に災害対応を行うために、1)地理情報の共有および流通のための標準インタフェース(Web Map Service)を有すること、2)Web-GIS を用いることの2つを満たすGISを提案した。2011年東北地方太平洋沖地震において、災害ボランティアセンターおよび地方自治体に対して、提案した要件を満たしたGIS(eコミマップ)による被災地支援を行った事例を示し、提案した2つの要件の有効性を確認した。

アメンボ類は特性長さが1cm、特性体重が10 dyne の昆虫で、池や川、外洋の水面に生息している。アメンボの体重は、自由表面が湾曲して生じた表面張力によって支えられており、水をはじく左右の中足を漕ぐように動かして進む。これまでの研究からは、アメンボの流体力学的な推進力は、漕ぐ脚が発する半球状の渦と表面張力波によって、下にある流体に運動量を輸送していることが明らかになった。本研究の目的はアメンボが素早く足を動かす瞬間にアメンボと流体との運動量の交換を定量化することである。デジタル粒子画像計測法(DPIV)技術を用いて水の流れを可視化した。アメンボの脚の素早い瞬間の動きが水の運動量に与える影響を定量化し、その結果アメンボの推進効率を算出する。

This paper discusses cake-cutting protocols when the cake is a heterogeneous good, represented by an interval on the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Meta-envy-free means there is no envy on role assignments, that is, no party wants to exchange his/her role in the protocol with the one of any other party. If there is an envy on role assignments, the protocol cannot be actually executed because there is no settlement on which party plays which role in the protocol. A similar definition, envy-freeness, is widely discussed. Envy-free means that no player wants to exchange his/her part of the cake with that of any other player's. Though envy-freeness was considered to be one of the most important desirable properties, envy-freeness does not prevent envy about role assignment in the protocols. We define meta-envy-freeness to formalize this kind of envy. We propose that simultaneously achieving meta-envy-free and envy-free is desirable in cake-cutting. We show that current envy-free cake-cutting protocols do not satisfy meta-envy-freeness. Formerly proposed properties such as strong envy-free, exact, and equitable do not directly consider this type of envy and these properties are very difficult to realize. This paper then shows cake-cutting protocols for two and three party cases that simultaneously achieves envy-free and meta-envy-free. Last, we show meta-envy-free pie-cutting protocols.
