An instance of difficulty in mouth opening as around 2mm due to impingement of fractured coronoid process and zygomatic arch in 30-year-old man who had met with a traffic accident was observed and surgical operation was done. After removal of the fractured coronoid process and elevation of the depressed malunited zygomatic arch, the patient could open mouth by now about 30mm.

In this paper, we analyse online word-of-mouth and Korean box-office sales data based on kernel regression method. To do this, we consider the regression model with mixed-data and apply the least square cross-validation method proposed by Li and Racine (2004) to the model. We found the box-office sales can be explained by volume of online word-of-mouth and the characteristics of the movies.

This study identified online information characteristics and investigated the effects of information characteristics on word of mouth performance in online environment. And the comsumer knowledge was found to be a moderator of the relationship between information characteristics and WOM performance in online environment. The implication of this work to both researchers and practitioners were discussed.

The author conducted an clinical study of closed mouth impression technique with a case of complete denture patient of favorable ridge contour to see the effect on the lingual border molding of lower denture. As a result, the shape of the border was formulated a quite different contour from the open mouth impression technique. The obtained contour had to be reshaped considerably. It was found that functional harmony with the surrounding tissue was difficult to be maintained. However, the contour is surely stable and favorable form for the retention of the lower denture provided patient is possible to adapt.

Burning mouth syndrome(BMS) is a burning sensation in the oral mucosa and $doesn^{\circ}$Øt have any identifiable oral lesion and organic etiology. Diagnosis of BMS is mainly based on clinical features and serial exclusion of other possible causes. There is no specific examination for BMS and that could embarrasse the dentist. In this study, the characteristics, differential diagnosis and several treatments of BMS are presented so that dentists can better diagnose BMS to maintain a good relationship with the patients.

Numerical calculations are made in order to find a possible correlation between the J-integral and the crack mouth opening displacement(CMOD) in dynamic nonlinear fracture experiments of 3-point bend(3PB) specimens. Both elastic-plastic and elastic-viscoplastic materials are considered at different impact velocities. The J-integral may be estimated from the crack mouth opening displacement which can be measured directly from photographs taken during dynamic experiments.

Mandibular implant overdenture is a good treatment option for complete edentulous patients with restoring removable prosthesis. Mandibular implant overdenture with two implants and locator attachments is widely used. It is tissue-supported overdenture that is made with the concept of conventional complete denture fabrication. There are two patients who provided impressions by open mouth technique and closed mouth technique in each case. In both cases, mandibular implant overdentures were restored with functionally and aesthetically satisfying results.

Foot and mouth disease (FMD) is highly infectious disease of cloven-hoofed animals, particularly cattle, sheep, pigs and goats. Last outbreak reported in November, 2010 induced the enormous social and economical impacts. Culling of infected animals, movement control, and vaccination are the major control measures of FMD. The aim of this study was to detection foot-and-mouth disease virus (FMDV) in the soil and leachate from modeling burial for pig carcass as measured by real-time reverse transcriptase polymerase chain reaction (RT-PCR). FMDV and Coxsakievirus B1 (CVB1) were detected in soil by week 16 and Coxsakievirus B1 (CVB1) by weeks 12, respectively. FMDV and CVB1 also detected by weeks 8 in the leachate. Results from this study provides an evidence that FMDV could be inactivated for safe of pig carcasses infected with FMDV within 4 month in the carcass burial site.

The purpose of this study is to examine factors influencing online product transformation focusing on benefits of online shopping and word of mouth. Generally, it has been known that buying search goods is more proper than experience goods in the online. However benefits of online shopping and word of mouth make product transformation from experience goods to search goods and the product transformation promote the purchase of experience goods online. We developed a conceptual model of online product transformation including benefits of online shopping(e.g. good price and convenience), online word of mouth (e.g. bulletin board and consumer reviews), and consumer characteristics (e.g. innovativeness and Internet usage). Also, we suggest several research propositions on online product transformation. The implications for marketing strategies of experience goods and furher research direction are suggested.

Dermoid cyst is a benign neoplasm, so called by teratoma that is derived from both ectoderm and mesoderm during embryonic period. The majority of dermoid cysts are found in the ovaries and approximately only 7% of dermoid cysts are found in the head and neck. The growth of dermoid cysts in the floor of the mouth is considered a rare condition. We report one case of huge dermoid cyst in the floor of mouth suffered with double chin appearance and difficulty in pronunciation and respiration. The cyst was excised successfully only intra-oral incision. Clinical progress was uneventful and postoperative recovery excellent without recurrence.
