Fundoplication is a common surgical procedure for gastroesophageal reflux disease (GERD). Recently the procedure has been performed with increased frequency laparoscopically. The aim of this study is to review our 11 years experience with fundoplication in infants and children. From October 1994 to December 2005, 59 fundoplications in 55 patients were performed at Sungkyunkwan University Samsung Medical Center. Medical records and laboratory results of these children were retrospectively reviewed for sex, age, symptoms and signs, coexisting disease, diagnostic methods, treatment modalities and length of operative time. Open fundoplication was performed in 41 cases and laparoscopic fundoplication in 18 cases. Simultaneous gastrostomy was done in 27 cases. Recurrent GERD symptom occurred in four patients (7.2 %) within 2 years after first fundoplication and all 4 patients had re-do fundoplication. There were no intra- and immediate post-operative complications. Gastrointesitnal symptoms were the most common indication for fundoplication in neurologically normal patients. The most frequent diagnostic studies were upper gastrointestinal series (76.3 %) and 24 hour esophageal pH monitoring (78.2 %). Fundoplication had been increased since 2004 and mostly done laparoscopically. In conclusion, our 11 years' practice of open and laparoscopic fundoplication indicates that both approaches are safe and effective in the treatment of GERD for infants and children.

The purpose of this study is to anticipate the air travel demands over the period of 164 months, from January 1997 to August 2010 using ARIMA-Intervention modeling on the selected sample data. The sample data is composed of the number of the passengers who in the domestic route for Jeju route. In the analysis work of this study, the past events which are assumed to have affected the demands for the air travel routes to Jeju in different periods were used as the intervention variables. The impacts of such variables were reflected in the presupposed demand. The intervention variables used in this study are, respectively, the World Cup event in 2002 (from May to June), 2003 SARS outbreak (from April to May), Tsunami in January 2005, and the influenza outbreak from October to December 2009. The result of the above mentioned analysis revealed that the negative intervention events, like a global outbreak of an epidemic did have negative impact on the air travel demands in a risk aversion by the users of the aviation services. However, in case of the negative intervention events in limited area, where there are possible substituting destinations for the tourists, the impact was positive in terms of the air travel demands for substituting destinations due to the rational expectation of the users as they searched for other options. Also in this study, it was discovered that there is not a binding correlation between a nation wide mega-event, such as the World Cup games in 2002, and the increased air travel demands over a short-term period.

This study was designed to analyse a few of aroma gas quantitatively. For three essential oil gas such as sweetorange, roman chamomile, and jasmine, the composition were analysed by GC/MS, the odor intensity andconcentrations were quantified by olfactory method, and the response patterns were analysed by MOS(metaloxide sensors) system. As the results, more than 70% component of sweet orange was limonene as a majorcomposition. While jasmine was composed with various components of relatively high molecular weight andhydrophobicity, roman chamomile was composed with lower molecular weight of substances. The results ofodor intensity and concentrations of aroma gas appeared to have clear linear relations with the outputs of thegas sensor system, showing the possibility of quantifying the concentration of essential oil gas with gas sensorsystem. In addition, patterns of essential oil gas could be classified according with the difference of sensitivityof gas sensors.

Paranasal sinus mucocele is a slowly expanding benign lesion which can occur as a result of obstruction in the sinus ostium or ostial tract. Frontal sinus mucocele differ from mucoceles of other sinuses in that the frontal outflow tract is usually narrower and less accessible. Since the introduction of endoscopic sinus surgical instrument and techniques, there has been an increasing trend towards the use of endoscopic transnasal technique for managing the paranasal sinus mucoceles. Some studies also recommend the use of intrafrontal stent to reduce the rate of restenosis of frontal sinus outflow tract. We experienced a case of recurrent frontal sinus mucocele complicated by visual disturbance and periorbital swelling. To treat this condition, an intranasal marsupialization was performed and an intrafrontal stent was applied. This paper reports the particulars of this case with a review of related literature.
