Interviews were conducted using a questionnaire regarding the current status of collaboration among community-based medical facilities and patient support system in ten central community hospitals. It was revealed that although the size and position of the sections varied, all hospitals were trying to facilitate collaboration among other community-based medical facilities by developing stronger relationships with family doctors. They mainly focused on improving the quality of services for referred patients and referring physicians. Besides, all hospitals possessed another section providing patient support services such as patient education and counseling. Staffs in the sections were trying to build stronger relationship with other health-related and medical facilities in their communities. Finally, it is discussed regarding how to facilitate collaboration among community-based medical facilities and provide patient support system in a university hospital. kn-abstract=本研究の目的は, 1)県下中核病院の地域医療連携,患者支援活動の現状について面接調査を行い,その実態を明らかにすること, 2)その結果をもとに,今後の特定機能病院に求められる地域医療連携や患者支援のあり方を検討する上での参考にすること,の2点にあった｡県下10か所の地域中核病院を対象に,地域医療連携業務やその他の患者支援活動に関する質問紙を作成し,面接調査を行った｡その結果,医療連携部門の歴史や業務内容は様々であったが,どの病院も地域医療連携部門を設置することで,開業医との連携を強化し,紹介･逆紹介の円滑化を図ろうとしている状況がうかがえた｡特に連携業務の中 でも,開業医からの紹介患者を病院にスムーズに受け入れる機能を重視している傾向が見られた｡また,すべての対象病院が地域医療連携以外の患者支援活動を行う部門を有しており,医療相談や地域の医療保健施設との連携強化等の業務を主に行っていた｡これらの調査結果をもとに,特定機能病院である大学病院に求められる地域医療連携･患者支援のあり方について考察した｡ en-copyright= kn-copyright= en-aut-name=NagamuneNoriyo en-aut-sei=Nagamune en-aut-mei=Noriyo kn-aut-name=長宗典代 kn-aut-sei=長宗 kn-aut-mei=典代 aut-affil-num=1 ORCID= en-aut-name=NakanishiYoshiko en-aut-sei=Nakanishi en-aut-mei=Yoshiko kn-aut-name=中西代志子 kn-aut-sei=中西 kn-aut-mei=代志子 aut-affil-num=2 ORCID= en-aut-name=KawataChieko en-aut-sei=Kawata en-aut-mei=Chieko kn-aut-name=川田智恵子 kn-aut-sei=川田 kn-aut-mei=智恵子 aut-affil-num=3 ORCID= en-aut-name=OhtaNiwa en-aut-sei=Ohta en-aut-mei=Niwa kn-aut-name=太田にわ kn-aut-sei=太田 kn-aut-mei=にわ aut-affil-num=4 ORCID= en-aut-name=HayashiYuko en-aut-sei=Hayashi en-aut-mei=Yuko kn-aut-name=林優子 kn-aut-sei=林 kn-aut-mei=優子 aut-affil-num=5 ORCID= en-aut-name=YasukataFumiko en-aut-sei=Yasukata en-aut-mei=Fumiko kn-aut-name=安酸史子 kn-aut-sei=安酸 kn-aut-mei=史子 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=3 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=4 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=5 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 affil-num=6 en-affil= kn-affil=岡山大学医学部保健学科看護学専攻 en-keyword=地域医療連携 (collaboration among community-based medical facilities) kn-keyword=地域医療連携 (collaboration among community-based medical facilities) en-keyword=患者支援システム (patient support system) kn-keyword=患者支援システム (patient support system) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=119 end-page=122 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case report of Homalogaster paloniae from the cecum of a bull in Fukuyama City kn-title=牛の盲腸に寄生した平腹双口吸虫Homalogaster paloniaeの1症例 en-subtitle= kn-subtitle= en-abstract=Twenty-two worms were taken out from the cecum of a bull at the slaughterhouse in Fukuyama City.

A constant amplitude and frequency vibration was applied to a dental implant model and the acceleration signal was detected using measuring probe. Then the IM score was obtained using the criteria developed in this study. We made several implant models of different implant lengths, diameters and material of Rigolac? or Molteno?. There was a linear relationship between mechanical mobility at 400 Hz of the models and the IM scores (R(2) = 0.92). The IM checker could discriminate the mobility of dental implant models in twelve measurements with P < 0.01. There was no significant difference in the means of the IM score measured by four operators with P < 0.01. The results indicated that the IM checker had sufficient reliability and could be available in dental clinics. en-copyright= kn-copyright= en-aut-name=Kusuma WijayaSastra en-aut-sei=Kusuma Wijaya en-aut-mei=Sastra kn-aut-name=クスマ ウイジャヤサストラ kn-aut-sei=クスマ ウイジャヤ kn-aut-mei=サストラ aut-affil-num=1 ORCID= en-aut-name=OkaHisao en-aut-sei=Oka en-aut-mei=Hisao kn-aut-name=岡久雄 kn-aut-sei=岡 kn-aut-mei=久雄 aut-affil-num=2 ORCID= en-aut-name=SarataniKeiji en-aut-sei=Saratani en-aut-mei=Keiji kn-aut-name=更谷啓治 kn-aut-sei=更谷 kn-aut-mei=啓治 aut-affil-num=3 ORCID= en-aut-name=MatsutaniYoshio en-aut-sei=Matsutani en-aut-mei=Yoshio kn-aut-name=松谷善雄 kn-aut-sei=松谷 kn-aut-mei=善雄 aut-affil-num=4 ORCID= en-aut-name=TatsutaMitsuhiro en-aut-sei=Tatsuta en-aut-mei=Mitsuhiro kn-aut-name=龍田光弘 kn-aut-sei=龍田 kn-aut-mei=光弘 aut-affil-num=5 ORCID= en-aut-name=KawazoeTakayoshi en-aut-sei=Kawazoe en-aut-mei=Takayoshi kn-aut-name=川添堯彬 kn-aut-sei=川添 kn-aut-mei=堯彬 aut-affil-num=6 ORCID= en-aut-name=KojimaHideki en-aut-sei=Kojima en-aut-mei=Hideki kn-aut-name=小嶋英幹 kn-aut-sei=小嶋 kn-aut-mei=英幹 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科検査技術科学専攻 affil-num=3 en-affil= kn-affil=大阪歯科大学有歯補綴咬合学講座 affil-num=4 en-affil= kn-affil=大阪歯科大学有歯補綴咬合学講座 affil-num=5 en-affil= kn-affil=大阪歯科大学有歯補綴咬合学講座 affil-num=6 en-affil= kn-affil=大阪歯科大学有歯補綴咬合学講座 affil-num=7 en-affil= kn-affil=隆祥産業株式会社生産本部技術部 en-keyword=Tooth mobility (歯の動揺) kn-keyword=Tooth mobility (歯の動揺) en-keyword=mechanical mobility (機械モビリティ) kn-keyword=mechanical mobility (機械モビリティ) en-keyword=dental implant (インプラント) kn-keyword=dental implant (インプラント) en-keyword=manual examination (触診) kn-keyword=manual examination (触診) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=101 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=加温後のtsAF8細胞の細胞周期 kn-title=Cell cycle of tsAF8 after heating en-subtitle= kn-subtitle= en-abstract=tsAF8細胞は45℃の加温後34℃で培養すると温熱耐性が速やかに発現するが,加温後,制限温度である39.7℃で培養すると温熱耐性の発現が抑制される｡加温後の培養温度が細胞周期に影響し,その結果として温熱耐性発現に影響を与えている可能性があることから,今回,Propidium Iodide(PI)とbromodeoxyuridine(BrdU)でtsAF8細胞を二重染色し,フローサイトメトリーによって温熱耐性と細胞周期の関係の有無について調べた｡tsAF8細胞を45℃20分の加温後34℃で培養すると,6時間後にはG(1)期の細胞が減少し,12時間後にはG(2)/M期への蓄積が見られた｡しかし,加温後39.7℃で培養した場合には細胞周期の進行がほとんど見られなかった｡BrdU の取込みは,加温せずに39.7℃で培養した場合には活発に行われ,また,45℃20分加温後34℃で培養した場合には,6時間後にはBrdUの取り込みは65.1%まで回復した｡しかし,温熱耐性発現の抑制が観察される45℃20分加温後39.7℃で培養した場合には,BrdUの取込み量は6時間後に一時的に15.1%に回復するが,12時間後には取込み量はゼロとなった｡BrdUの取り込みが阻害されたのはstep-down heatingの現象による細胞生存率の減少が原因だと考えられたが,温熱耐性発現の抑制が観察される条件下では細胞周期の特定の時期への集積がなかったことから,温熱耐性と細胞周期との関係はtsAF8細胞においては見い出されなかった｡ kn-abstract=Thermotolerance in tsAF8 cells develops during incubation at 34℃ after heating at 45℃, while it is suppressed by the following incubation at a non-permissive temperature of 39.7℃ after the same heating. The incubation temperature after heating may affect the cell cycle and consequently thermotolerance. In the present study, a relationship between the thermotolerance and the cell cycle of tsAF8 was investigated. The cell cycle fractions and DNA synthesis were measured by flow cytometry using double staining with propidium iodide and bromodeoxyuridine. When the tsAF8 cells were heated at 45℃ for 20 min, and thereafter incubated at 34℃, bromodeoxyuridine uptake in the S phase cells (DNA synthesis) was recovered to 65.1% 6 h after the heating, and the cells showed gradual accumulation in the G(2)/M phase. When the cells were incubated at 39.7℃ after heating at 45℃ for 20 min, then showed inhibition of thermotolerance development, the DNA synthesis was recovered to 15.1% temporarily 6 h after the heating, but it became 0% after 12 h, and the cells did not remarkably accumulate in any phases of the cell cycle. This inhibition of DNA synthesis at 39.7℃ was considered to be the result of cell survival decreasing by a step-down heating. However, the relationship between the thermotolerance and the cell cycle was not found out in tsAF8 cells, because the cells did not accumulate in any phases of the cell cycle under the inhibitory condition of thermotolerance. en-copyright= kn-copyright= en-aut-name=ShibuyaKoichi en-aut-sei=Shibuya en-aut-mei=Koichi kn-aut-name=澁谷光一 kn-aut-sei=澁谷 kn-aut-mei=光一 aut-affil-num=1 ORCID= en-aut-name=KawasakiShoji en-aut-sei=Kawasaki en-aut-mei=Shoji kn-aut-name=川崎祥二 kn-aut-sei=川崎 kn-aut-mei=祥二 aut-affil-num=2 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name=黒田昌宏 kn-aut-sei=黒田 kn-aut-mei=昌宏 aut-affil-num=3 ORCID= en-aut-name=AsaumiJun-ichi en-aut-sei=Asaumi en-aut-mei=Jun-ichi kn-aut-name=浅海淳一 kn-aut-sei=浅海 kn-aut-mei=淳一 aut-affil-num=4 ORCID= en-aut-name=KatoHirokazu en-aut-sei=Kato en-aut-mei=Hirokazu kn-aut-name=加藤博和 kn-aut-sei=加藤 kn-aut-mei=博和 aut-affil-num=5 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院放射線科 affil-num=4 en-affil= kn-affil=岡山大学歯学部附属病院歯科放射線科 affil-num=5 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院放射線科 en-keyword=thermotolerance (温熱耐性) kn-keyword=thermotolerance (温熱耐性) en-keyword=hyperthermia (ハイパーサーミア) kn-keyword=hyperthermia (ハイパーサーミア) en-keyword=tsAF8 kn-keyword=tsAF8 en-keyword=cell cycle (細胞周期) kn-keyword=cell cycle (細胞周期) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=91 end-page=99 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=放射線エネルギーの違いによる喉頭癌における吸収線量の影響 kn-title=Influence of the dose to the laryngeal cancer by the difference in radiation beam energy en-subtitle= kn-subtitle= en-abstract=Tl声門癌に対して放射線治療を単独で行うのは確立している方法である｡しかし,頚部は解剖学的に複雑であり,前方に薄いX字形で,喉頭が気道に隣接している構造を持つので,病巣への線量はbuild-upとbuild-downの影響による線量低下が生じることが考えられる｡すなわち,放射線エネルギーの選択が喉頭癌の局所的制御に影響を及ぼすと言える｡この影響は,より高い放射線エネルギーでは,それに伴いより強く起きるということが基礎実験にて報告されている｡また,それらの線量測定は,熱ルミネセンス線量計(TLD)のような従来の測定システムで測定されていた｡しかし,空気空洞へTLD を単体 で浮かせ線量を正確に測定し評価を行うのは困難である｡本研究において,我々は Gafchromic MD-55 film (Nuclear Associates, Inc.)を使用し測定した｡ Gafchromic MD-55 film は,フィルムタイプ線量計でありエネルギー依存性がなく,3〜100 Gyを測定可能であり,アクリル製頸部ファントムの空気組織境界面及び,空洞部に線量計を容易に精度良く配置することが可能である｡また,この線量計は人体の軟部組織に近い組成である｡そこで, 4, 6および10MVの各エネルギーでこの線量計を用いてエネルギーの違いによる,頸部ファントムを用いて喉頭の線量評価を行った｡その結果,我々は,特に放射線エネルギー10MVで頸部ファントムにおける,前部組織-組織空洞境界面-空洞部の一連したbuild-upおよびbuild-downを線量計で評価することができた｡これらの研究の結果､前交連浸潤を有するT1-T2に相当する声門癌患者は,放射線エネルギー6MVおよび10MVではなく,4MVを用いることによって,より効果的な放射線治療を行えると推測できる。 kn-abstract=We investigated the usefulness of Gafchromic MD-55 film (Nuclear Associates, Inc.) for measuring the radiation doses on the radiotherapy of laryngeal cancers. Since larynx has thin wedge-shaped structure in anterior neck adjacent to airway, the radiation doses to the lesion may be diminished because of build-up and build-down. So, the dose has been measured with conventional measuring systems such as thermoluminescent dosimetry (TLD). However, it was not possible to evaluate the dose distribution correctly using TLD, because it is impossible to float a TLD chip in an air cavity. In this study, we employed Gafchromic MD-55 film as a dosimeter, for it can be set on the area of interest and with a measurability of dose range of 3 to 100 Gy, though it has no energy dependency. And this radiometer is composition near the soft tissue of the human body. The dose distributions to larynx were investigated with this film using neck phantom under each radiation beam energy of 4, 6 and 10 MV x-rays. Our neck phantom is made from acrylic resin and simulates a normal larynx on the basis of image information of computed tomography (CT). Moreover we observed secondary build-up and build-down curves in tissue in the vicinity of air cavities, especially at 10 MV x-rays. These findings suggest that patients with TI-T2 glottic cancers with anterior commissure invasion may receive more effective treatment with 4 MV x-rays rather than with 6 MV and 10 MV x-rays. en-copyright= kn-copyright= en-aut-name=AoyamaHideki en-aut-sei=Aoyama en-aut-mei=Hideki kn-aut-name=青山英樹 kn-aut-sei=青山 kn-aut-mei=英樹 aut-affil-num=1 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=2 ORCID= en-aut-name=InoueMitsuhiro en-aut-sei=Inoue en-aut-mei=Mitsuhiro kn-aut-name=井上光広 kn-aut-sei=井上 kn-aut-mei=光広 aut-affil-num=3 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=4 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=5 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=6 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=7 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=3 en-affil= kn-affil=財団法人操風会岡山旭東病院放射線課 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学講座 en-keyword=Gafchromic MD-55-2 film kn-keyword=Gafchromic MD-55-2 film en-keyword=radiation dose kn-keyword=radiation dose en-keyword=build-up kn-keyword=build-up en-keyword=build-down kn-keyword=build-down en-keyword=glottic cancer kn-keyword=glottic cancer END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=83 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Suitability on the densitometry systematize in Laser Densitometer Model 1710 for Gafchromic MD-55-2 film kn-title=Gafchromic MD-55-2 fi1mのLaser Densitometer Model 1710における線量計測体系上の適合性 en-subtitle= kn-subtitle= en-abstract=For the medical advancement, the speedy technical innovation is performed also in the radiotherapy. When patients can search for QOL (Quality of Life), the radiation therapy is one of the choices. The radiation therapy system for limited irradiation to lesion without affecting normal tissue has been developed over several years. On the technology of external irradiation in our country, the level is improving to clinical stage from study grade. In such things, a new requirement will come out also as for the measuring method of the medication dose. However, conventional various radiometers have many problems to the dosimetry of the new radiotherapy method. Gafchromic MD-55-2 film, which has new form of radiochromic film based on poly-diacetylene and has been introduced for medical applications recently, is expected to solve some problems. Now, in clinical usage of this film, there is no comprehensive guideline for densitometry system and it's calibration yet. So, in this paper, the densitometry of Gafchromic MD-55-2 film was performed with Laser Densitometer Model 1710 for general-purpose film dosimetry system. And then, problems in the densitometry were extracted and the accuracy of dosimetry was investigated. kn-abstract=医療の高度化に伴い,放射線治療分野においても急速な技術革新が行われている｡QOL(Quality of Life)を考慮に入れた治療が求められる多くの場合,放射線治療が大きな選択肢の一つであることは言うまでもない｡このような状況下の中で,正常組織に影響を与えず病巣に限局した放射線を照射する技術が開発され,外照射においては,欧米に習い我が国でも研究段階から臨床へ移り変わろうとしている｡その際に,投与線量評価を欠かすことができないが,従来から使用されているいずれの線量計も新しい治療法に対応しきれていない｡そこで,フィルムタイプ線量計, Gafchromic MD-55-2 film の開発により,いくつかの問題が解決されてきている｡しかし,この線量計を精度良く測定する濃度測定器が必要になるが,現段階において規格化されたガイドラインが存在しないのが現状である｡そこで本研究では,当施設で保有している]線フィルム線量測定用 Laser Densitometer Model 1710 を用いて Gafchromic MD-55-2 fllm による線量測定を行い,問題点の抽出を行うとともに線量測定精度の考察を行った｡ en-copyright= kn-copyright= en-aut-name=AoyamaHideki en-aut-sei=Aoyama en-aut-mei=Hideki kn-aut-name=青山英樹 kn-aut-sei=青山 kn-aut-mei=英樹 aut-affil-num=1 ORCID= en-aut-name=NakagiriYoshitada en-aut-sei=Nakagiri en-aut-mei=Yoshitada kn-aut-name=中桐義忠 kn-aut-sei=中桐 kn-aut-mei=義忠 aut-affil-num=2 ORCID= en-aut-name=InoueMitsuhiro en-aut-sei=Inoue en-aut-mei=Mitsuhiro kn-aut-name=井上光広 kn-aut-sei=井上 kn-aut-mei=光広 aut-affil-num=3 ORCID= en-aut-name=InamuraKeiji en-aut-sei=Inamura en-aut-mei=Keiji kn-aut-name=稲村圭司 kn-aut-sei=稲村 kn-aut-mei=圭司 aut-affil-num=4 ORCID= en-aut-name=TaharaSeiji en-aut-sei=Tahara en-aut-mei=Seiji kn-aut-name=田原誠司 kn-aut-sei=田原 kn-aut-mei=誠司 aut-affil-num=5 ORCID= en-aut-name=UnoHirofumi en-aut-sei=Uno en-aut-mei=Hirofumi kn-aut-name=宇野弘文 kn-aut-sei=宇野 kn-aut-mei=弘文 aut-affil-num=6 ORCID= en-aut-name=MoriokaYasuki en-aut-sei=Morioka en-aut-mei=Yasuki kn-aut-name=森岡泰樹 kn-aut-sei=森岡 kn-aut-mei=泰樹 aut-affil-num=7 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=2 en-affil= kn-affil=岡山大学医学部保健学科放射線技術科学専攻 affil-num=3 en-affil= kn-affil=財団法人操風会岡山旭東病院放射線課 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院中央放射線部 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学講座 en-keyword=Gafchromic MD-55-2 film kn-keyword=Gafchromic MD-55-2 film en-keyword=Laser Densitometer Model 1710 kn-keyword=Laser Densitometer Model 1710 en-keyword=濃度測定器制御ソフトウェア (Control software of densitometry system) kn-keyword=濃度測定器制御ソフトウェア (Control software of densitometry system) en-keyword=測定精度 (Accuracy of measurement) kn-keyword=測定精度 (Accuracy of measurement) END
