Epidermoid cysts located in floor of mouth can be easily removed intraorally. The cysts inferior to mylohyoid muscle have been excised transcervically. However, an intraoral removal of a cyst extended inferior to mylohyoid muscle has not been reported yet. A 20-year-old female visited to the hospital with a cystic mass in submental region. Neck computed tomography revealed a 6.0${\times}$4.3cm sized circumscribed cystic mass in midline of submental area. The cyst lied external to the genioglossal and geniohyoid muscle, extending inferior to mylohyoid muscle. The mass was removed successfully by intraoral approach. It was performed under the exposure by the division of genioglossal and geniohyoid muscle, traction of the cystic wall after aspiration of the cyst, and digital compression externally.

The purpose of this study was to measure the oral temperature, skin temperature, and subjective discomfort according to the application time of ice bag on thigh, head, and abdomen. This study was also intended to suggest nursing principles about ice bag application by exploring the recovery time of skin temperature after the removal of ice bag. The design of this study was $8{\times}3$ factorial design with one sample repeated measure. Here, the application time of ice bag(criteria, 5min, 10min, 20min, 30min, 40min, 50min, 60min) and the application site of ice bag(thigh, head, abdomen) were independent variables. The subjects were 10 university woman students, and data collection was made from July, 1 to August 30, 1992. Rubber ice bag halfly filled with ice was covered with towel and applied on thigh, head and abdomen in other three days. Before applying the ice bag, oral temperature and skin temperature were checked for criteria. After ice bag was applied, skin temperature, oral temperature and VAS score were checked at first 5 minutes elapsed, and every 10 minutes until 60 minutes. After that, ice bag was removed, and oral temperature and skin temperature were also measured every ten minutes until 60 minutes. In this study, skin temperature and core temperature were measured by thermistor probe, and subjective discomfort was measured by 200mm VAS (Visual Analogue Scale). Some of the findings were as follows : 1. There were significant differences in skin temperature among the three application sites of ice bag as time go by. It was most decreased to $15.87^{\circ}C$ in thigh, and $19.47^{\circ}C$ in abdomen at 50 minutes after the application of ice bag, whereas $26.1^{\circ}C$ at 40 minutes in head. Before the application of ice bag, skin temperature showed significant differences in three sites, so that they were compared after the criteria was covariated. In other words, there was significantly more decrease of skin temperature in thigh and abdomen than head, after ice bag was applied for 20 minutes and more. 2. There was no significant difference in core temperature among the three application sites of ice bag during the time of application 3. There was no significant difference in subjective discomfort (VAS) among the three application sites of ice bag. 4. After the removal of ice bag, the recovery of skin temperature was significantly different in three sites during first 30 minutes. In head, skin temperature came up to criteria at 30 minutes after the removal of ice bag, but it was not recovered In thigh and abdomen even 60 minutes elapsed. 5. After the removal of ice bag, there was no significant difference in oral temperature among the three application sites of ice bag. 6. There was significant correlation between the skin temperature and VAS score only in thigh. In conclusion, it is suggested that head in more suitable site for the application of ice bag if it is used for the relief of fever or pain. When we apply ice bag on thigh or abdomen for the relief of pain, careful attention is required.

Congenital intratympanic membrane cholesteatoma (ITMC) is a rare type of congenital cholesteatoma located within the tympanic membrane. This lesion tends to increase in size over time. The development of ITMC can cause several complications such as hearing impairment, dizziness, facial palsy, and intracranial complications, similar to any other cholesteatoma. The treatment of congenital cholesteatoma requires the removal of the lesion through surgery, because disease progression induces bony destruction of the nearby tissue. Most patients presenting with this cholesteatoma type are also treated with primary surgical removal. However, we recently experienced a case of an ITMC that showed a natural transition to an external auditory canal cholesteatoma.

Chemical mechanical polishing (CMP) has been widely accepted for the global planarization of multi-layer structures in semiconductor manufacturing. However, it still has various problems to the CMP equipment, in particular, among the CMP components, process variables are very important parameters in determining the removal rate and non-uniformity. Using a design of experiment (DOE) approach, this study was performed investigating the interaction between the various parameters such as turntable and head speed, down force and back pressure during CMP. Using statistical analysis techniques, a better understanding of the interaction behavior between the various parameters and the effect on removal rate, no-uniformity and ETC (edge to center) is achieved.

Positive airway pressure (PAP) is currently recommended as a primary treatment for obstructive sleep apnea syndrome (OSAS) and positively affects various subjective and objective parameters related to OSAS, such as the apnea-hypopnea index, excessive daytime sleepiness, and blood pressure. However, PAP also exhibits various adverse effects, including skin breakdown, pressure intolerance, claustrophobia, unintentional mask removal, mouth leaks, and dryness. Especially, unintentional mask removal due to nasal obstruction may result in poor PAP compliance. A 47-year-old male patient with severe OSAS who had low PAP compliance due to nasal obstruction underwent nasal surgery. After the surgery, nasal obstruction was corrected and the patient experienced improved PAP compliance (from 30.4% to 86.7%). This case demonstrates that nasal surgery may be useful for improving PAP compliance in OSAS patients with nasal obstruction.

Bronchial foreign body aspiration (BFA) is a common but emergent condition in infants and children. Furthermore, it can result in various complications such as atelectasis, pneumonia, bronchiectasis, and pneumothorax. Among these, pneumothorax is a very rare complication. However, it can be fatal without the swift implementation of appropriate treatment. We experienced a case of 16-month-old girl with an aspirated peanut. The foreign body was fixed in her left main bronchus. A CO₂ laser was used to safely cut and break the foreign body. Removal was successful after breaking it. But after the process, inflammatory tissue of the tracheal mucosa was ruptured. Bilateral tension pneumothorax followed after the rupture. The patient was treated with bilateral chest tube insertion. Here we present this BFA case with a rare and unexpected complication. We also review the appropriate literature.
