2011年3月に起きた東日本大震災に伴い発生した東京電力福島第一原子力発電所における事故において、日本原子力研究開発機構では最初の1年間にのべ約45,000人の職員が本来の職場を離れて電話相談,一時帰宅支援,環境モニタリングなどの支援業務に従事した。特に、住民と直接に接する電話相談に従事した職員には、感情労働に伴うストレスがかかった。同機構の核燃料サイクル工学研究所ではこれらの支援業務に従事した職員に対して、組織的なメンタルヘルスケアを行った。本論文では今回の活動を「支援者の支援」の具体例と位置づけ、原子力災害において住民等の支援を行う職員のメンタルヘルスについて考察した。

被引用回数：22 パーセンタイル：48.24(Peripheral Vascular Disease)Seasonal variation in serum lipid levels in Japanese population remains unclear. The aim of this study was to determine whether the variation in lipid levels exists in Japanese workers. We investigated a total of 1,331 employees in our institution (1,192 men, 44
10 years; 139 women, 3811 years) who underwent health checkups in both June (summer) and December (winter), 2008. Serum levels of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, and triglyceride were significantly higher in winter than in summer (129.131.2 mg/dL versus 125.230.2 mg/dL, 
0.0001; 65.916.8 mg/dL versus 63.516.1 mg/dL, 0.0001; 110.467.5 mg/dL versus 107.570.4 mg/dL, 0.05; respectively), although the ratio of LDL to HDL cholesterol was comparable (2.110.81 in summer versus 2.120.81 in winter). Frequency of study subjects diagnosed hypercholesterolemia defined as LDL cholesterol 
140 mg/dL was significantly higher in winter than in summer (34.5% versus 30.9%, 0.0001). In Japanese workers, we demonstrated that there is seasonal variation in serum lipid levels and prevalence of hypercholesterolemia. This result indicates that we have to give careful consideration to the season of blood sampling in clinical diagnosis and management decisions of hypercholesterolemia.

被引用回数：47 パーセンタイル：72.81(Peripheral Vascular Disease)Accumulating evidences have demonstrated that seasonal variations exist in metabolic syndrome parameters. The aim of this study was to examine the hypothesis that there is seasonal variation in metabolic syndrome prevalence in Japanese subjects. We investigated a total of 1,202 male workers in our institution (44 10 years), who underwent health checkups in both June (summer) and December (winter), 2008. In this study, metabolic syndrome was defined according to the criteria proposed by National Cholesterol Education Program (NCEP), International Diabetes Federation (IDF), and Japanese Society of Internal Medicine (JSIM). Serum levels of high-density lipoprotein-cholesterol and fasting glucose, and blood pressure (BP) were significantly higher in winter than in summer, whereas waist circumference and serum levels of triglyceride were little changed. Prevalence of NCEP-, IDF-, and JSIM- metabolic syndrome in this study was 3.8, 15.1 and 12.4% in winter, 3.2, 10.7 and 8.4% in summer, respectively. Out of the metabolic syndrome components, elevated BP component was mainly connected with the seasonal variation of metabolic syndrome prevalence. The present study demonstrated the seasonal variation in metabolic syndrome prevalence in Japanese male workers. This result indicates that season of health checkups may affect a clinical diagnosis and management of metabolic syndrome.

本研究は、重装備の身体的負荷の緩和を目指して実施しているものである。本件は、最適な防護装備の選定や防護装備の性能評価を行ううえで、重要なパラメータの一つである身体負荷の定量的な指標として生理学的指標に着目し、東海再処理施設の放射線作業において、データの収集・調査を行い、まとめたものである。その結果、作業前後の体重の減少量が身体負荷の定量的な指標として有効であることが確認された。
