This paper statistically analyzes residents’ understanding of problems related to radioactively contaminated water discharged from nuclear power and nuclear reprocessing plants. Moreover, this paper examines their impact on the surrounding fisheries by using the cases of La Hague, Sellafield, and Fukushima Daiichi Nuclear Power Plant. Survey data shows that more than 60% respondents disagree with the release of contaminated water, and this sentiment is particularly strong among both British and French respondents. Regarding seafood caught in the vicinity of the nuclear power and nuclear reprocessing plants, although British respondents noted that they hold it in high regard, many people do not purchase this seafood. In contrast, many Japanese respondents reported that they were less concerned, and thus, willingly purchase seafood caught off the coast of Fukushima Prefecture. In all three countries, many people did not trust government information on the release of contaminated water. Compensation to the affected people was provided by the central government, companies involved, and local governments, in that order. Japanese and British respondents reported higher expectation for compensation as compared to French respondents. Japanese and French respondents noted that they have knowledge of radioactive materials and contaminated water, and many of them purchased seafood caught in the vicinity of the nuclear power and reprocessing plants. British respondents were the most opposed to the release of contaminated water, whereas Japanese respondents were the least reliant on government information about the release of contaminated water. Finally, among those who trusted information from the government and retailers, French respondents were the least concerned about contamination. French respondents were also the least likely to expect any compensation for the fishermen affected by contamination. Both British and French residents around the affected plants expected the central government to compensate the affected fishermen, whereas those who did not reside around the affected plants did not expect the fishermen to be compensated. French respondents were more likely to expect compensation from the local governments; affluent respondents were more likely to expect the compensation to be funded by taxation, whereas less affluent respondents expected them to be funded by donations. Respondents who were more skeptical of government information wanted the companies involved to compensate the fishermen. British respondents reported a tendency for wanting the companies involved to provide this compensation, and did not support the concept of compensation provided through donations.

Background:Previous randomized clinical studies have raised concerns about whether inferior vena cava filter (IVCF) can benefit patients with venous thromboembolism (VTE). The present study therefore investigated whether IVCF are associated with in-hospital mortality in Japan.Methods and Results:This study was based on the Diagnosis Procedure Combination database in the Japanese Registry of All Cardiac and Vascular Datasets (JROAD-DPC). Of 2,368,165 patients included in JROAD-DPC, we identified 28,238 who were hospitalized with VTE between 2012 and 2014. We compared in-hospital mortality rates between patients with or without IVCF using propensity score (PS) matching. PS were estimated using logistic regression models in which IVCF was the dependent variable. The other variables consisted of age, sex, Charlson comorbidity index, anti-thrombotic agents and clinical disease status. Patients were aged 68±16 years, and 59.7% were female. Of 28,238 patients, 6,937 (24.5%) were treated with an IVCF. The overall in-hospital mortality was 4.3%. On PS-matched analysis in-hospital mortality was significantly lower with, than without, IVCF (3.1% vs. 4.4%, P<0.001; OR, 0.65; 95% CI: 0.54–0.79).Conclusions:Having an IVCF was independently associated with lower in-hospital mortality in Japanese patients with VTE. This is in sharp contrast to the benefits of IVCF in other countries. The reasons for this difference require further investigation.

本稿では、栃木産にっこりととちおとめが、香港やバンコクの如何なる購買層に評価されるのか、プロビットモデルを推計し、考察した。分析の結果、下記の諸点が明らかにされた。まず、香港・バンコクにおける国産ナシ品種と国産イチゴ品種の認知度は非常に低かった。今後、栃木産にっこりととちおとめを輸出する際は、輸出専用パッケージ等による品種のイメージアップを図る必要があるだろう。そして、とちおとめは香港では大きさが、バンコクでは香りが評価された。そして、にっこりは中高年層に、とちおとめは女性に評価が高かった。最後に、香港でのにっこりの価格は中国産ナシの4倍、バンコクでのとちおとめの価格はタイ産イチゴの7倍の価格差があった。そして、香港ではにっこりは8割弱が、とちおとめも7割弱が、調査当日の小売価格または若干高くても購入するという回答が得られた。ただし、バンコクでは8割弱が、調査当日の店頭小売価格ならば購入しないという結果となった。そして、プロビットモデルの推計結果から判断するならば、今後の香港でのとちおとめ輸出は、中高年層をターゲットとし、食味評価の高い女性を如何に購買層に取り入れるかが輸出拡大のカギとなるだろう。

In this article, we analyzed the effects of radioactive contamination from the Semipalatinsk nuclear test site on food choices in Kazakhstan. Nearly 90% of citizens in Kazakhstan knew their health had been affected by radioactive material from the nuclear test site, with more than 50% of citizens still confirming the safety of foodstuffs regarding radioactive materials when purchasing food. However, citizens in the vicinity of the nuclear test site did not take countermeasures against internal exposure due to declining fear of radioactivity, despite refraining from purchasing food from near the nuclear test site. More than 80% of Kazakhstan understood that exposure to radioactive materials was both external and internal. Further, Kazakhs were more aware of the effects of internal exposure on the human body than either Ukrainians or Japanese. Elderly people who remembered the times when nuclear tests had been conducted were aware of radioactive materials in food. High-income individuals took measures to control radioactive contamination in consideration of their nutritional balance, while low-income individuals refrained from purchasing food from near the nuclear test site as a means of controlling potential contamination. In Kazakhstan, more than 60% of citizens did not take measures against internal exposure, but the number of citizens who were concerned about radioactive materials was much higher than in either Ukraine or Japan. In Kazakhstan, 30–40% of citizens, particularly women, would buy at least 20% more if foodstuffs with lower than the regulated level of radioactive materials were sold.

本稿では、葉取らず、無袋、有袋といった3 つの栽培リンゴについて、色、糖度、価格を消費者に評価してもらい、総合的に比較検討した。その結果、葉取らずの糖度、有袋の色づきの評価は非常に高かった。色づき・甘さとも評価された無袋秋星・北斗・シナノスイート等の中生種は甘さと価格の相関が、有袋ふじ・むつ等は色づきと甘さの相関が確認された。そして一般的に色づきや糖度を評価するのは高齢者や高所得者であった。さらに、品種の価格差が30 円程度ならば若干高くとも高く評価したリンゴを購入するが、100 円以上の価格差がついた場合は購入せず、有袋ふじや無袋秋星を購入する者は著しく減る結果となった。ただし、有袋ふじ・むつ、無袋秋星は、高齢者や高所得者に販売が期待でき、葉取らず・有袋といった栽培方法を上手く使い分けることで、よりよい販売環境の構築が可能になると思われる。

Objective Among treatment options for coronavirus infectious disease 2019 (COVID-19), well-studied oral medications are limited. We conducted a multicenter non-randomized, uncontrolled single-arm prospective study to assess the efficacy and safety of favipiravir for patients with COVID-19. Methods One hundred participants were sequentially recruited to 2 cohorts: cohort 1 (Day 1: 1,600 mg/day, Day 2 to 14: 600 mg/day, n=50) and cohort 2 (Day 1: 1,800 mg/day, Day 2 to 14: 800 mg/day, n=50). The efficacy endpoint was the negative conversion rate of SARS-CoV-2, and the odds ratio (OR) of cohort 2 to cohort 1 for negative conversion on Day 10 was calculated. Characteristics of all participants and profiles of adverse events (AEs) were collected and analyzed. Results The mean age of participants was 62.8±17.6 years old. Thirty-four patients (34.0%) experienced worsening pneumonia, 7 (7.0%) were intubated, and 4 (4.0%) died during the observation period. Cohort 2 showed a higher negative conversion rate than cohort 1 (adjusted OR 3.32 [95% confidence interval, 1.17 to 9.38], p=0.024), and this association was maintained after adjusting for the age, sex, body mass index, and baseline C-reactive protein level. Regarding adverse events, hyperuricemia was most frequently observed followed by an elevation of the liver enzyme levels (all-grade: 49.0%, Grade ≥3: 12.0%), and cohort 2 tended to have a higher incidence than cohort 1. However, no remarkable association of adverse events was observed between patients <65 and ≥65 years old. Conclusion The antiviral efficacy of favipiravir was difficult to interpret due to the limitation of the study design. However, no remarkable issues with safety or tolerability associated with favipiravir were observed, even in elderly patients with COVID-19.

本稿は、果実の地域需要が如何に変化し、如何なる要因によって地域間格差が存在したのかを、地方及び都道府県の側面から、需要関数を推定することによって明らかにした。分析の結果を要約すると以下の通りである。(1)3大地域別データに基づく需要分析では、1973年のオイルショック後、1988年の貿易自由化・バブル崩壊後、国内需要に変化が見られたが、前者の変化の方が大きかった。(2)都道府県別データに基づく需要分析では、果実需要の減退を表す変数を導入し推定したが、国内外産を問わず、主要5 果実の需要は大きく減退した。各果実の価格弾力性は、みかんでは産地において非弾力的であるが、りんご、なし、すいかでは産地でも弾力的であった。また、みかん、バナナは全国的に平準化した需要形態をとるが、りんご、なし、すいかなどは、地域特化した需要形態をとり、現在でも地域間格差が大きい。
