対話行為とは,話者が発話において持つ何かしらの「意図」あるいは発話における「機能」であり,その意図や機能の種類として対話行為タグが定義される.対話行為は,対話モデルにおける基本単位の一つとして利用されてきており,特に近年,対話における発話間の相互作用をモデル化する上で有用であることが知られている.しかし,近年広く用いられているニューラル対話モデル (Neural Conversation Model; NCM) では,こうした対話行為によってシステム発話を明示的に操作することが困難である.そこで本研究では,システム応答が持つ対話行為の情報を条件として用いた敵対的生成学習の枠組みをNCMに導入する.具体的には,与えられた対話行為に基づいて応答を生成するGeneratorと,Generatorが生成した応答が指定した対話行為に基づいた適切なものであるかを判別するDiscriminatorを構築し,これらの2つのモデルを交互に敵対的に訓練する.このような学習の枠組みの導入により,NCMが任意の対話行為に基づいた適切な応答を生成することが可能かどうかの評価を行った.

Aim: To assist in the long-term health management of residents and evaluate health impacts after the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Plant accident in Fukushima Prefecture, the Fukushima prefectural government decided to conduct the Fukushima Health Management Survey. This report describes the results for residents aged 16 years or older who received the health check examinations and evaluates the data obtained from 2011 and 2012.Methods: The target group consisted of residents aged 16 years or older who had lived in the evacuation zone. The health check examinations were performed on receipt of an application for a health check examination from any of the residents. The examinations, including measurements of height, weight, abdominal circumference/body mass index (BMI), blood pressure, biochemical laboratory findings, and peripheral blood findings, were performed as required.Results: 1) A total of 56,399 (30.9%) and 47,009 (25.4%) residents aged 16 years or older received health checks in 2011 and 2012, respectively. 2) In both years, a number of male and female residents in the 16-39 year age group were found to suffer obesity, hyperlipidemia, hyperuricemia, or liver dysfunction, and the prevalence of obesity and hyperlipidemia among residents increased with age. Furthermore, the proportion of residents with hypertension, glucose metabolic abnormalities or renal dysfunction was higher in those aged 40 years or older. 3) The frequencies of obesity, hypertension and hyperlipidemia among residents in 2012 were lower than those in 2011. However, the prevalence of liver dysfunction, hyperuricemia, glucose metabolic abnormalities and renal dysfunction among residents was higher in 2012 than in 2011.Conclusions: These results suggested the number of residents who had lived in the evacuation zone with obesity, hyperlipidemia, hyperuricemia, liver dysfunction, hypertension, glucose metabolic abnormalities, or renal dysfunction increased with age in all age groups. Therefore, we think that it is necessary to continue with health check examinations for these residents in order to ameliorate lifestyle-related disease.

Background: Positive and negative psychological factors are associated with mortality and cardiovascular disease. This study prospectively investigated associations between daily frequency of laughter, and mortality and cardiovascular disease in a community-based population.Methods: This study included 17,152 subjects ≥40 years old who participated in an annual health check in Yamagata Prefecture. Self-reported daily frequency of laughter was grouped into 3 categories (≥1/week; ≥1/month but <1/week; <1/month). Associations between daily frequency of laughter and increase in all-cause mortality and cardiovascular disease incidence were determined using Cox proportional hazards modeling.Results: During follow-up (median, 5.4 years), 257 subjects died and 138 subjects experienced cardiovascular events. Kaplan-Meier analysis revealed that all-cause mortality and cardiovascular disease incidence were significantly higher among subjects with a low frequency of laughter (log-rank P<0.01). Cox proportional hazard model analysis adjusted for age, gender, hypertension, smoking, and alcohol drinking status showed that risk of all-cause mortality was significantly higher in subjects who laughed <1/month than in subjects who laughed ≥1/week (hazard ratio (HR) 1.95, 95% confidence interval (CI), 1.16-3.09). Similarly, risk of cardiovascular events was higher in subjects who laughed ≥1/month but < 1/week than in subjects who laughed ≥1/week (HR 1.62, 95% CI, 1.07-2.40).Conclusion: Daily frequency of laughter represents an independent risk factor for all-cause mortality and cardiovascular disease in a Japanese general population.

Several studies have reported that the supplementation of long-chain polyunsaturated fatty acids (LCPUFA), such as docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) improve cognitive function in the elderly. However, the doses used in these studies were higher than general dietary LCPUFA intake levels. This randomized, double-blind, placebo-controlled trial evaluated the effects of low doses of LCPUFA supplementation corresponding to general dietary intake on cognitive function in non-demented elderly Japanese participants. Japanese men aged 55-64 years were enrolled and randomly allocated to the placebo or LCPUFA group. Participants received 4 weeks of supplementation with LCPUFA-containing oil (DHA, 300 mg/day; EPA, 100 mg/day; and ARA, 120 mg/day) or purified olive oil as placebo. Event-related potential P300, reflecting cognitive processes, was measured before and after supplementation. A total of 113 participants completed the supplementation period, and the per-protocol analysis included 69 participants. Changes in P300 latency were significantly different between the placebo group (+13.6 msec) and the LCPUFA group (-1.8 msec) after supplementation. Significant increases in DHA (+0.9%) and ARA (+0.6%) contents in plasma phospholipids were observed in the LCPUFA group; no changes were observed in the placebo group. Dietary DHA, EPA, and ARA intake were in the normal range for Japan participants and remained unchanged during the study. These results suggest that low doses of LCPUFA supplementation have the potential to improve cognitive function in elderly Japanese men.

ブログ上の文書には口語的な表現や特有の表記などのくだけた表現が多数含まれるため,一般の形態素解析器を用いても十分な解析精度を得ることはできない.くだけた表現は人手により辞書登録されることが一般的であるが,人的コストの大きさや専門的な知識を必要とすることが課題である.本稿ではくだけた表現を正規な表現に修正することで高精度な形態素解析を実現する手法を提案する.提案手法ではくだけた表現の修正候補文字列をくだけた表現の少ない文書から自動的に検索し,修正ルールを生成する.生成した多数の修正ルールから文脈に適した修正ルールを選択的に適用するために,検索結果における修正候補文字列の出現頻度,修正前後の文字列間における編集距離,修正前後の文の形態素解析結果の比較,を用いて修正ルールをスコアリングする手法を合わせて提案する.提案手法と従来手法の性能比較評価実験を行い,各手法における未知語の出現率や単語区切りの正確さ,修正前後の文の意味変化を定量的に評価した.提案手法では従来手法と同程度の単語区切りの正確さを維持しながら,対象文章の未知語出現数を 36.1% 減少させることに成功した.これは従来手法における未知語減少数の 2.5 倍以上である.

This paper describes the relationship between basic spatial recognition and landscaping In Japan. Landscaping m Japan is based on the concept and idea of "Creation and Generation of Space". There is a spatial concept that I call "Space of Island" that has a symbolic position in above mentioned relationship. The story of "The Creation of the Main 8 Islands of Japan" in Japanese mythology teaches us the framework on spatial recognition to understand the meaning of variable landscapes and scenery in Japan. This study clarifies conceptions and patterns on composition of "Spatial Axis" as "Creation and Generation of Space".
