en-abstract=The purpose of this study is to clarify what a nursing care brought some changes in a hemodialysis patient's behavior. Based on Bandura's self-efficacy theory and on a concept of "speech and action for clue" proposed by Kawaguchi et al, the nursing care was discussed. The results were as follows : (1) Nurses made positive environments in which for the patient to express his emotion frankly through nurse's acceptable and empathic manner. (2) Nurses appropriately caught the patient's speech and action as clue to change in his behavior. (3) Nurses helped the patient consider his behavioral objectives that he can carry out by himself. (4) Nurses supported the patient and evaluated his behavior, and helped him succeed in his task so that he could improve his self-efficacy.
kn-abstract=体重増加が著しく，嘔気や嘔吐を繰り返していた透析患者が，看護婦とのかかわりの中で，徐々に体重コントロールが出来るように変化していった。そこで，透析患者に行動変容をもたらした看護援助が何であったのかを明らかにすることを目的として，本事例を振り返り，Banduraの「自己効力理論」と，河口らの，行動変容への「とっかかり言動」の概念に基づいて考察した。その結果，患者に行動変容をもたらした看護援助は以下のようであることがわかった。(1)患者の気持ちや行動を受け止め，共感することで，患者が感情表出しやすい環境を整えた。(2)患者の行動変容に結びつく言動を逃さずキャッチした。(3)「それぐらいならできそう」という，患者にとって身近で実行可能な行動目標を共に考えた。(4)患者が成功体験を積み重ねることが出来るように，患者を支援し，行動を評価して，患者の自己効力を高めた。

en-title=Analysis of three cases of renal transplant recipients whose feelings about life have become negative after transplantation
kn-title=腎移植後に人生の受けとめ方が低下した3事例の分析
en-subtitle=

en-abstract=We are seeking an effective nursing intervention for renal transplant recipients based on a nursing support model described by Hayashi. Among 119 patients we investigated, at least 90% of them experienced increased positive feelings about their lives after receiving a renal transplant, whereas three of them answered differently. The purpose of this study is to analyze the complaints of three recipients after renal transplantation. Factors such as age, gender, marital status, time-course after transplant, and type of kidney transplant are included in the study. As a result, their complaints are differentiated into 4 categories : (1) status of transplanted kidney and their own health, (2) status of medical support, or assistance from their friends and
others, (3) situation of their immediate family, (4) a grade of their ability to fulfill their
social and familial responsibilities. These results are important in our nursing approach in order to improve the quality of life (QOL) of renal transplant recipients.
kn-abstract=筆者らは，林が作成した看護援助モデルに基づき，腎移植者への効果的な看護介入についての検討を行っている。その一環として，今回，腎移植を受けた119名を対象に，QOLや移植前と現在の人生に対する受けとめ方について調査した。人生に対する受けとめ方の移植前後の変化を分析したところ，ほぼ全数に近い腎移植者が移植前と比べよい状態であると受けとめていたが，3事例において受けとめ方が低下していた。そこで，この3事例に着目し，これらの事例が日常生活の中で不満を抱いている事柄を分析した。その結果，移植後に人生に対する受けとめ方が低下した3事例が抱く不満は，1．腎臓・健康などの身体状況，2．家庭環境，3．医療・友人・他人からのサポート，4．家族や社会の中で役割を果たす能力の4カテゴリーに分類された。移植後の人生の受けとめ方の否定的変化には，上記の4カテゴリーに対して抱く不満が影響していることが推測され，腎移植後の看護介入を検討する上で考慮すべき点であることが明らかになった。

en-title=Interpersonal values in 4-year course nursing students : Comparisons with 3-year course nursing students and students not majoring in nursing science
kn-title=4年制看護課程入学者の対人関係価値：3年制看護学生，非看護系学生との比較
en-subtitle=
kn-subtitle=
en-abstract=This survey studied the interpersonal values held by a cohort of students admitted to a four-year course of nursing program in 1999 to determine whether they had the
same interpersonal values as the third-year course nursing students. The KG-SIV (Kikuchi-Gordon Survey of Interpersonal Values) was administered twice at the beginning of the program. The subjects described 'self' for the first testing, while they described 'ideal nurse' for the second testing. Their scores on the self and the ideal nurse were compared with those obtained for three cohorts of nursing students who started the three-year course of nursing program in 1990, 1993 and 1996, respectively. Their scores on self were also compared with the scores obtained for four-year course students not majoring in nursing. Analyses showed that compared to the students not majoring in nursing the four-year course nursing students rated the values of Benevolence
and Conformity as more important, while they rated the values of Support, Recognition and Independence as less important. Their scores were simliar to the scores given by the three-year course nursing students. Also, the values of Support and Independence increased while those of Benevolence decreased across the four cohorts of nursing students. It was concluded that nursing students hold distinctive interpersonal values as compared to non-nurses irrespective of their particular nursing program. Such values are ones that are beneficial to the nursing profession.
kn-abstract=1999年4年制看護課程に入学した看護学生の入学時の対人関係価値をKG-SIVによって現実の自己像とナースの理想像について調査し，これを同年に非看護課程に入学した学生と3年制看護課程に異なる時期（1990年，1993年，1996年）に入学した看護学生3コホートと比較した。その結果，4年制看護学生は非看護学生に比べ，「博愛」と「同調」を重視する程度が強く，「支持」と「承認」，「独立」を重視する程度が弱かった。また，彼女ら
の対人関係価値は3年制看護課程の学生のそれに類似していた。さらに，コホートの年次的移行のなかで看護学生の対人関係価値は「支持」と「独立」への動機づけが増大し，「博愛」への動機づけが滅退する傾向を見せた。

en-abstract=The purpose of this study was to examine what nursing students had learned through on site gerontological nursing practice for 2 weeks. The data were collected from conference records written by 47 students. And the contents of conference recoeds were analyzed by means of content analysis. The conference records were divided into 3 categories and 8 subcategories. The following results were obtained. �@During the first week, almost all students felt lost concerning the elderly, but　during the next week, students strived to understand them better. �AIn the geriatic hospital, the students learned characteristics of the aged by taking care of them. In the home for the aged, the students learned the importance of individual care by helping them. We need to take into more consideration, the relation between what the students learned and the goals of the nursing practice.
kn-abstract=当医療技術短期大学部（以下医療短大と略す）の老人看護学実習は，特別養護老人ホーム（以下老人ホームと略す）と老人病棟のどちらかの施設で2週間の実習を行っている。今回は老人看護学実習での学生の学びの内容を把握する目的で，平成10年度のカンファレンスノートの記録を分析した。対象者は医療短大3年生75名のうちカンファレンスの記録が残っていた47名を分析の対象にした。内容分析の手法を用いて研究者2人で分析を行った。その結果，3つのカテゴリー，8つのサブカテゴリーに分類され，以下の2点が示唆
された。�@実習の1週目では学生は，実習形態の違いやコミュニケーションがとれないことに戸惑っているが，2週目には日常生活の援助を通して相手を理解しようと努力していた。�A老人病棟では治療の必要な患者のケアを通して高齢者の特徴を学び，老人ホームでは，生活の援助を通して個別性の大切さを学んでいた。以上の結果から，2週間の老人看護学実習を通して学生は，高齢者への理解を深めていることが明らかになった。今後は学生の学びと実習目標との関連についても検討が必要である。

en-subtitle=

en-abstract=In radiation controlled areas, measures have been taken to assess the radiation dose to workers, but these efforts are limited due to high labor and cost factors in extremely low dose radiation controlled areas. And so they have been expected to be rationalized. Therefore, we first reviewed the present conditions of these working environment measurement and elucidated the relationship between surface and airborne contamination in radiation controlled areas. Second, we reviewed the qualities of several surface contamination measurements such as smear test and possibilities for their improvement. As a result, we developed some future programs for rationalization of the working environment measurements, for example, an algorithm for selecting the proper surface contamination measurement for each measurement area based on the conditions specific to that area.
kn-abstract=放射線管理区域において業務従事者の放射線防護が正確に実施されていることを確認するために放射性同位元素の環境測定が行われている。しかし，実際の測定においては，濃度が低いなど実測困難な場合が多いこと，多くの人手と経費を要していることから，より合理的な測定の実施ができないかということについての検討が期待されている。このため本総説では，まず大学などの放射線管理区域における作業環境測定方法の現状についてまとめた。次に，放射線管理区域の床，作業台などにおける放射性同位元素の表面汚染と空気汚染に着目し，汚染粒子の移行など表面汚染と空気汚染の関係機構について，また，スミア法や直接測定法などの各種表面汚染測定法の汚染採取効率などを指標とした特性とこれら測定法の改良の試みについてまとめた。さらに，実際の作業場所において，作業内容，換気，表面材料などが表面汚染と空気汚染の関係に及ぼす影響について，その検討例を紹介した。得られた知見をまとめるとともに，測定箇所・測定頻度の適性化やそれぞれの測定箇所に適した測定法の選定など作業環境測定の一層の合理化に向けて，今後どのような検討が必要なのかについて提案した。

en-title=Influence on the character of films used for density control of an automatic processor by the difference in the way of preserving
kn-title=保存方法の違いによる自動現像機の濃度管理用フィルム特性への影響
en-subtitle=
kn-subtitle=
en-abstract=Though there are various reports on the way of preserving films used for density control of the automatic processor, it is hard to say that the best method isestablished. In　addition, the influences on density control or their comparisons by the difference way of preserving film between regular and orthochromatic films have been hardly reported until now. In this paper, three ways of preserving films were employed, which were at a room temperature, in a refrigeration and in a freezer after the films were opened, using a regular film, Fuji new-RX and three orthochromatic films, Konica SR-G, SR-V and SR-H. We investigated the influences on gross fog, speed index and average gradient of four films on three different ways of preserving film for 35 weeks. As a result, new-RX film wasn't influenced by the ways of the preservation. On the other hand, the orthochromatic films were so influences sensitively that the films couldn't be used for density control. It was considered that sensitizing dye stuff 
got denatured by dew condensation.
kn-abstract=自動現像機の濃度管理に用いられるフィルムの保存については，種々の報告がなされており，最良の方法が確立されているとは言い難い。さらに，レギュラフィルムとオルソフィルムの保存方法の違いによる濃度管理への影響，あるいはこれらの比較については，これまでほとんど報告されていない。本論文では，われわれは，レギュラフィルム，フジnew-RXとオルソフィルム，コニカSR-G，SR−VおよびSR-Hを用い，開封後，室温，冷蔵，冷凍の3種類の保存方法を採用した。われわれは，35週間3種類の保存方法で4種類
のフィルムのgross　fog，speed indexとaverage gradientへの影響を調査した。その結果レギュラフィルムは，3種類の保存方法による差が認められなかった。オルソフィルムでは，冷蔵・冷凍保存に大きな特性変動が認められた。その原因として，オルソフィルムは増感色素が結露に対して敏感に影響を受けたと考えられた。

en-title=Variations of parameters of bioelectrical impedance during upper limb movement
kn-title=上肢運動に伴う生体電気インピーダンスのパラメータの変動
en-subtitle=
kn-subtitle=
en-abstract=We have proposed new biodynamic analysis methods using bioelectrical impedance. Variations of human limb electrical impedance during biodynamics were caused by variations of equivalent cross sectional area of muscle and variations of blood volume. However these variations could not be directly measured. Therefore quantitative discussions about relation between the impedance and these variations have been insufficient. In this work, we explained variations of the impedance with variations of parameters of an equivalent circuit. The model of impedance was Cole-Cole type. The equivalent circuit consisted of five individual parameters as follows : extracellular fluid resistance, 'Re', intracellular　fluid　resistance, 'Ri', characteristic frequency of dispersion, 'fm' and parameters of dispersion of relaxation time, 'α' and 'β'. Impedances of forearm and upper arm were measured with four electrode method during flexion and extension of joints in upper limb. The ratio of variations of equivalent series resistance R was linear-approximated using the above mentioned parameters. The influences of parameters on variations of R was confirmed. R was strongly influenced by Re and Ri, However there were differences between influence of Re and that of Ri in difference measured part and difference joint movement. This showed the conditibn of the muscle. In case of the maximum　flexion of the elbow joint, R of upper arm was influenced by fm. This means that a polarization of cell membrane changes and influences impedance during movement. These results are significant in evaluation of biodynamics including difference of strength of movement and condition of exhaustion.
kn-abstract=これまでに生体電気インピーダンスを用いて身体運動の解析を行ってきた。インピーダンスの変動原因は測定部位の等価断面積変化および貯血量変化と説明できるが，直接的に断面積変化や貯血量変化を測定することは困難であるため，その変動原因の定量的な検討は不十分であった。そこで，本研究では上肢運動に伴う生体電気インピーダンスの変動原因を生体の等価回路のパラメータの変動で説明する。インピーダンスのモデルはCole−Cole型であり，等価回路は，細胞外液抵抗Re，細胞内液抵抗Ri，分散の特性周波fm　fm，緩和時間の分布の程度を表すα，βの独立した5パラメータで表現した。
上肢の肘関節および手関節の屈曲運動野に伴う前腕部および上腕部の電気インピーダンスを測定した。まず，電気インピーダンスの等価直列抵抗Rの変動率をパラメータの変動率で線形近似し，その信頼性と各パラメータ変動のRへの影響を確認した。Rへの影響はReとRiが支配的であるが，測定部位や運動の違いにより，それぞれの影響が異なることを示した。これは測定部位の筋活動状態の違いを表すものである。さらに，肘関節最大屈曲におけるRの変化にはfmの変化が大きく依存しており，上肢運動のインピーダンス変化には細胞膜の分極特性の変化も影響していることを明らかにした。本研究の結果は，運動強度の違いや疲労状態における身体運動評価に有意義である。
