The purpose of this study was to create a theoretical structure for the concept of purchasing risks by identifying the structure of purchasing risks that lead to obstacles in the purchasing decisions of consumers in fashion consumption via online channels. This was a secondary research using books, articles, prior researches, and academic journals on the five topics of “characteristics of fashion consumption,” “the concept of purchasing risks,” “purchasing risks by product types,” “purchasing risks by channel types,” and “purchasing risks of fashion consumption on online shopping channels.” According to the arguments of prior researches, the study divided the purchasing risks of fashion consumption through online shopping into four categories : (1) fundamental purchasing risks including financial risk and time loss risk pertaining to any product or channel, (2) online channel purchase risks, which include risks in payment, Information leaks, and delivery and return/exchange risk, (3) fashion product risk related to product quality or experience of other people, which includes social risks and risks associated with quality, and (4) the online channel×fashion product risks, which include the aesthetic and psychological hazards especially amplified in online channels. The four risk factors were then described with a concept map to systemize the multidimensional and stereoscopic psychological structure of purchasing risks. Of the four risk factors, consumers placed the most emphasis on the online channel×fashion product risks, hence, reducing this risk factor is of utmost priority for marketing of online shopping channels.

방사선조사에 따른 백서 구개점막상피의 변화를 관찰하기 위하여 두경부에 6MV X선을 5Gy 및 10Gy 단일조사한 후 1시간, 3시간, 6시간, 12시간, 1일,3일,7일,14일, 그리고 28일에 회생시키고 광학현미경으로 조직학적 변화를 관찰하여 다음의 결과를 얻었다. 방사선조사후 3시간군과 6시간군에서 수포성 변화와 상피층 두께의 감소가 관찰되었고, 3일군에서는 기저세포의 증식으로 인한 상피층 두께의 증가와 상피융기의 신장이 관찰되었다. 경구개점막에서는 5Gy 조사후 7일군에서, 10Gy 조사후 28일군에서 회복되는 소견을 보였다. 또한 저작점막인 경구개점막에 비해 이장점막인 연구개점막에서 방사선조사로 인한 조직반응이 보다 분명하였고, 회복도 지연되었다. The purpose of this study was to investigate the irradiation effects on the palatal mucosa. For this study, Sprague-Dawley strain rats were irradiated to their head and neck region with the dose of 5Gy and 10Gy by 6MV X-radiation and sacrificed on the 1 hour, 3hours, 6 hours, 12 hours, 1 day, 3 days, 7 days, 14 days, and 28 days after irradiation. The author observed the histological changes of the hard and soft palatal mucosae. The results were as follows: In the light microscopic examination, hydropic change on the basal cells, increased cell size of the epithelium, and decreased epithelial cell layer were observed on the 3 hours, 6 hours, and 12 hours groups after irradiation. But, basal cell hyperplasia, increased epithelial cell layer, and elongated rete pegs were observed on the 3 days groups after irradiation. After then, these changes were recovered on the 7 days and 14 days groupsin the mucosa of hard palate, and 14 days and 28 days groups in the mucosa of the soft palate. Such changes were greater on the mucosa of the soft palate than on that of the hard palate, and more evident in 10Gy irradiated groups than in 5Gy irradiated groups.
