  • A 69-year-old man was admitted due to blood-tinged sputum. The preoperative examination revealed 5${\times}$2.8cm sized nodular mass on left upper lobe of the lung. The patient underwent left upper lobectomy and radical Iymph node dissection under impression of lung cancer. Postoperative pathologic examination revealed as primary choriocarcinoma of the lung. The patient expired at postoperative 58 days despite meticulous postoperative care. We planned on immediate adjuvant chemotherapy but was delayed due to postoperative pneumonia and the choriocarcinoma progressed rapidly. Primary choriocarcinoma is an extremely rare clinical entity in lung cancer with no established therapeutic guidelines available. We report a case of the primary pulmonary choriocarcinoma which was diagnosed postoperatively.

  • This study examines online art platforms as a new type of informational technology and seeks to verify the impact of the user's perceived value and acceptance of new technologies on the behavioral intention about art platforms. For this, it was conducted to survey 489 users of the online art platform. Several emotional value, functional value, social value, and value for money were selected as perceived value variables, and performance expectancy, effort expectancy, and facilitating conditions were set as variables of new technology adaptation. As evident in the correlation with perceived values, emotional value and social value have a significant impact on all parameters of new technology adaptation, while functional values and value for money only affect facilitating conditions and behavioral intention, respectively. Furthermore, the impact of acceptance of new technologies confirms that performance expectancy and facilitating conditions affect behavioral intention. This study demonstrates the perceived value of online art platform users and the acceptance of new technologies. Therefore, it is expected that platform providers will be able to use it as primary data to understand and reflect user requirements.
