<原著>コーピングにおける性差

本研究における目的は, CISS(Coping Inventory for Stressful Situation)日本語版を用いてコーピング(対処行動)における性差を検討した。調査対象は, 大学生, 専門学校生, 大学院生の男性95名, 女性100名の合計195名である。その結果, ストレスの原因となっている問題に対して計画的, 冷静に行動するという対処行動である課題優先コーピングでは男性が女性より有意に高く, コーピングにおける性差が認められた。つまり, 課題優先コーピングにおける性差は男性性の獲得を含む性役割の影響が推測される。The objective of this research was to study the difference of coping behaviors between young men and women based on the Japanese version of the CISS (Coping Inventory for Stressful Situation). The number of subject people was 95 males and 100 females, who were college, university and graduate students. The research has proved that there is a difference in coping behaviors between males and females because the figures for males were significantly higher than those for females in the task-oriented coping. However, in both the emotion-oriented coping and avoidance-oriented coping, a significant difference has not been found between males and females.国立情報学研究所で電子

Hardness of Approximate Nearest Neighbor Search

We prove conditional near-quadratic running time lower bounds for approximate Bichromatic Closest Pair with Euclidean, Manhattan, Hamming, or edit distance. Specifically, unless the Strong Exponential Time Hypothesis (SETH) is false, for every $\delta>0$ there exists a constant $\epsilon>0$ such that computing a $(1+\epsilon)$-approximation to the Bichromatic Closest Pair requires $n^{2-\delta}$ time. In particular, this implies a near-linear query time for Approximate Nearest Neighbor search with polynomial preprocessing time. Our reduction uses the Distributed PCP framework of [ARW'17], but obtains improved efficiency using Algebraic Geometry (AG) codes. Efficient PCPs from AG codes have been constructed in other settings before [BKKMS'16, BCGRS'17], but our construction is the first to yield new hardness results

要介護認定基準の変更と影響の同期検証 －2009 年10 月版と2006 年版一次判定の較差－

本研究では，要介護認定基準2009年10月版と，旧版要介護認定基準2006年版との較差を比較するために，経年的な対象者における要介護状況の変化を除外して，それぞれを同期検証することを研究目的とした。その比較する対象を，同一対象者で同一時期に，それぞれの要介護認定基準ごとに別々の認定調査員の認定調査結果から要介護認定一次判定を実施した。それぞれの認定調査結果から，要介護認定基準の変更と影響について，8施設（400名）と8在宅事業所（208名）の要介護者等608名を研究対象として分析した。同期検証した結果，総体的に2009年10月版は，平均合計要介護時間は3.37分ほど多めに有意差を持って算出された。要介護度の2006年版から2009年10月版での一致率は，半数近くの調査対象者の要介護度が変化して，軽度化する調査対象者も2割半前後いた。要介護5の一致率が64.23%と最も高く，要支援1の一致率は29.73%と最も低くなった。要介護5以上の要介護時間に該当する要介護者は2009年10月版の方が2006年版よりも多く分布し，動ける認知症の要介護度はその全体の41.67%も軽度化していた。要介護認定には，要介護基準等介護時間だけによらない総合的指標である総合介護度の構築が必要である。In this research, the accreditation criteria of certifi cation standards of long-term care needed level have been changed to be stricter at the fiscal year 2009 in Japan. The difference and influence were compared in the primary judgment between the fiscal year 2006 and the fiscal year 2009 October version at the synchronized analysis. As for the synchronized analysis, each different investigator surveyed the same long-term care needed or assisted at the simultaneous time with the certifi cation standard for long-term care needed with 2009 October and 2006 version. The change and the influence of them were detected by each investigation result of the 608 long-term care needed who used the services of 8 institutions or the 8 in-home facilities. As a result, total 3.37 minutes needed more average time for total long-term care was signifi cantly calculated by 2009 October than 2006 version(p<0.01). The long-care needed levels of the same respondents have been changed with over half coincidence rate between 2009 October and 2006 versions. The 2009 October version was possible to slightly improve about 25 percent of the long-term care assisted level from 2006 to 2009 October, version, too. At the long-term care needed level 5, the 64.23% coincidence rate of the long-term care needed level was highest. At the long-term care assisted level 1, the 29.73% coincidence rate of the long-term care assisted level was lowest. There were more time and number distribution over the long-term care needed level 5 calculated by 2009 October than 2006 versions. 41.67% of the self-movable dementia was considerably lightened at the long-term care moderately needed and assisted level. The certification standard for long-term care needed should be constructed by not only the long-term care time but also total factors with the burden or necessity indexes for the judgment of the long-term care needed.報告Report
