Tongue cancer는 혀에 생기는 악성종양으로 전체 암의 1.8%, oral cancer의 75%를 차지할 정도로 발생 빈도가 높은 것으로 알려져 있으며 초기 진단, 전이유무, 병기설정 등을 위해 PET/CT 검사를 실시하고 있다. Tongue cancer 환자의 PET/CT 검사 시 close mouth 상태로 Torso를 촬영하고 있으며 그에 따른 겹침이나 인공물의 영향으로 병소부위가 명확히 관찰되지 않는 경우가 발생되었다. 이에 open mouth로 PET/CT 검사 시 발생되는 변화와 그에 따른 유용성을 알아 보고자 한다. 20명의 환자(남 15명, 여 5명)를 대상으로 시행하였으며 먼저 close mouth 상태로 Torso 촬영 후 open mouth 상태로 1bed 추가 촬영하였다. Tumor(T), Normal Tongue(NT), Lymph Node(LN)에 관심영역을 설정하여 표준화섭취계수(standardized uptake value, SUV) $SUV_{mean}$, $SUV_{max}$를 측정하여 Background(Carotid artery) SUV를 빼주었다. Tumor size 변화를 측정하였으며 육안적 영상 해상도 평가는 blind test를 진행하였다. 비모수검정(wilcoxon signed rank test)을 통해 통계 분석하였다. Tumor에서 SUV는 open mouth 검사 시 증가하는 변화를 보였으며, normal tongue과 lymph node에서는 소폭의 변화가 있었으나 유의한 차이는 없었다. tumor size 변화와 blind test를 통해 전체적으로 비슷하거나 높은 영상 해상도를 보여주는 것을 확인할 수 있었다. Open mouth PET/CT 검사가 close mouth시 발생하는 문제점에 대한 완벽한 대안법이 될 수는 없지만 open mouth를 통해 구강 내 다른 구조물과의 겹침이나 tumor의 경계면을 조금 더 명확하게 관찰할 수 있을 것으로 사료된다.

This study delved into the complex nature of medical services as experience goods and trust services, investigating the profound impact of online word-of-mouth on medical consumers' decisions to visit hospitals. Considering the restrictive legal framework for medical advertising, consumers are increasingly dependent on unrestricted sources of information like online reviews. This research aimed to provide empirical evidence for the significant role online word-of-mouth plays in hospital selection. Utilizing data from Naver reviews, hospital choice factors were classified based on the Kano model, revealing the subtle yet significant influence that word-of-mouth has on consumers' hospital visit intentions beyond merely positive or negative messages. In particular, the study provided insights into how the categorized positive and negative information, along with the presence or absence of emotional expression, affects the efficacy of word-of-mouth. The experiment targeted medical consumers aged over 20 and, through analysis using the SPSS statistical program, yielded important findings. The direction of online word-of-mouth, the presence of emotional expression, and the interaction of Kano attributes all created significant differences in hospital visit intentions. Notably, emotional expression included in negative word-of-mouth concerning one-dimensional attributes markedly decreased visit intentions, whereas the absence of emotional expression in attractive attributes actually enhanced reliability and increased visit intentions. These findings offer critical implications for redefining strategies in medical marketing and online review management. The discoveries of this study underscore the importance of active engagement and strategic management of online reviews by medical service providers, urging careful consideration of the various elements of online word-of-mouth that influence medical consumers' hospital visit intentions.

Corporate Social Responsibility (CSR) program has become one of the primary concerns of companies worldwide. For many companies, treating the environment and the community well is important to business practice and reputation, and this is reflected in their CSR programs. CSR is a company's obligation to consider the interests of its employees, customers, shareholders, communities, and the environment and to consider the social and environmental consequences of their business activities. CSR plays an important role in relationship building with customers. Thus, the main purpose of this study is to analyze the relationship between customer perception of CSR and customer trust. The model of this study considers two mediating variables, i.e., company reputation and word of mouth to link CSR to customer trust. This study employs a causal survey design. The respondents were 160 consumers who have purchased products and knew about CSR programs of a global food company. Data analysis was using structural equation modeling (SEM) to test the hypotheses. The results of this study revealed that CSR negatively impacts customer trust. Furthermore, CSR positively impacts corporate reputation and word of mouth. Besides, this study found corporate reputation positively impacts word of mouth and customer trust. While the mediating effect of reputation and word of mouth also positively impacts the relationship between CSR and consumer trust. A good reputation and word of mouth could be connecting buyers and enhances the power of suppliers.

최대개구량은 측두하악관절과 저작계의 임상 기능 평가에 유용한 진단 도구이다. 이 연구는 한국 유치열기 어린이의 정상 최대개구량을 측정하고 관련 인자들 간의 상관관계를 조사함으로써, 소아 악관절 장애의 진단 및 치과치료시 안전한 개구 범위 정립에 기여할 수 있는 기초 자료를 마련하고자 하였다. 악관절장애가 없는 건강한 어린이(만2-6세) 151명을 대상으로 최대개구량을 측정하고, 성별, 연령, 신장, 체중과 입의 너비를 기록하였다. 평균 최대개구량은 $37.72{\pm}5.10mm$였고 성별에 따른 유의한 차이는 없었으나, 연령, 신장, 체중, 입의 너비 증가에 따라서는 유의하게 증가하였다(p < 0.05). 최대개구량과 관련 요인들 간의 상관관계 분석 결과, 신장에서 가장 높은 상관관계가 관찰되었다. 결론적으로 한국 유치열기 어린이의 정상 최대개구량에 관한 자료를 얻을 수 있었고, 이 연구는 소아 악관절장애의 진단 및 안전 개구 범위에 관한 기초 지식을 제공할 수 있을 것이다.

Respiration is one of the most important functions which are carried out in stomatognathic system. When nasal orifice is obstructed or the resistance of upper airway is increased mouth breathing is initiated. Mouth breathing is regarded as an important etiologic factor of dentofacial anomalies. This experiment was performed to observe the influences of metabolic acidosis, tracheal resistance and vagotomy on mouth breathing. After rabbits were anesthetized with sodium pentobarbital, a pair of wire electrode was inserted into mylohyoid muscle, anterior belly of digastric muscle and dilator naris muscle to record EMG activity. Femoral vein and artery were cannulated for infusion of 0.3N HCl and collection of blood sample to determine the blood pH, and tracheal intubation was done to control airway resistance. Mouth breathing was induced by metabolic acidosis. Increase of the airway resistance through tracheal cannula intensified the activity of dilator naris, mylohyoid and digastric muscle. The higher the resistance, the larger the EMG amplitude. After bilateral vagotomy, respiratory volume and inspiatory time were increased and the activities of dilator naris, mylohyoid and digastric muscle were strengthened. It was concluded that the muscle activity related to mouth breathing was induced by metabolic acidosis and increase of tracheal tube resistance.

The purposes of this study were to segment consumers by on-line word of month and to find the differences among the segmented groups in regard to fashion involvement, internet perceived risk, and internet purchase behavior. The subjects of this study were female consumers who were members of online cafe in Korea. The data were collected during October, 2004. The respondents returned the questionnaires through internet and 480 questionnaires were finally used in the data analysis. The statistical analyses used for the study were factor analysis, cluster analysis, t-test, and $X^2-test$. The results showed that word-of·mouth communication on internet(e-WOM) is composed of two factors, word-of-mouth transmission and word-of-mouth acceptance. These two factors were put under cluster analysis and were classified into two groups of the word-of·mouth communication: WOM group and non-WOM group. T-test showed that word-of-mouth communication groups were significantly different in regard to fashion involvement, internet perceived risk, and internet purchase behavior. For example, WOM group was more uncertain of their clothing choices, put more weight on the internal factors of clothing selection, and was a frequent purchaser of internet fashion products. Internet fashion business needs to implement the proper marketing strategies based on the results of the study.
