本研究の目的は，若者(高校生，大学生)のデジタルゲームに対するイメージ尺度を開発し，その信頼性と妥当性 を検討することである．予備調査として，デジタルゲーム開発を専門とする大学生 112 名に予備調査を行い，デジタルゲ ームに対するイメージを測定する項目として 115 項目を抽出した．その 115 項目を用いて，関西圏の高校生，大学生 360名を対象に調査を実施した．その結果，デジタルゲームに対するイメージとして，「個人的・社会的悪印象」，「特別体験・肯定的印象」，「スキル向上」，「広範的コミュニケーション」，「健康被害・依存誘発」，「思想的悪影響」，「運動不足」の 7因子(74 項目)が抽出された．

We present herein the case of a 38-year-old woman found to have an extremely large solitary primary paraganglioma of the lung. The patient presented with chest pain on exertion and a mass was discovered in the left lower lobe of the lung by chest X-rays and computed tomography (CT). As no other neoplasms were detected elsewhere, a left lower lobectomy was performed. The patient has remained well without any evidence of recurrence for 5 years since her operation. The tumor, measuring 13 x 12 x 7 cm, was composed of ovoid cells (Zellballen), which were positive for Fontana-Masson and Grimelius stains, and sustentacular cells. Immunohistochemically, the ovoid cells were positive for neuron-specific enolase, S-100, CAM5.2, Leu7, and chromogranin A, and negative for carcinoembryonic antigen and epithelial membrane antigen. The sustentacular cells were positive for S-100 protein and CAM5.2, and negative for glial fibrillary acid protein. Therefore, the tumor was diagnosed as a paraganglioma. The tumor from our patient is the largest of the 17 solitary primary pulmonary paragangliomas reported thus far in the English-language literature.
