The sialolithiasis is one of the most common disease that is found in the submandibular gland and they can be usually observed in the extra glandular area. As the lumen of Wharton's duct is larger and more expandable than that of Stensen's duct, the symptom of them is initially painless. Obstruction of salivary secretion by a sialolith can result in sudden swelling and pain, as well as infection of the gland. It can be observed with clinical exam and the scintigraphy. After removal of sialoliths, the majority of them can get the recovery of function. Our department performed the transoral sialolithotomy. One of three cases was recurred sialolithiasis with sialadenitis and was performed by the re-sialolithotomy and extraoral sialoadenectomy.

Sialolithiasis is the formation of calcific concretions within the ductal system of major or minor salivary glands. The exact nature of sialolith evolution is not known. It may occur at any age but, it is most common in middle-aged adult and rare in childhood. In this paper, a case of sialolithiasis just beneath the mucosa in the anterior portion of the Wharton's duct observed in a 5-year old boy. It was approximately $2.5{\times}5$ mm in size and has no clinical symptoms. Under local anesthesia, it was removed by dilatation of orifice of the duct and pressure on the floor of oral cavity by finger.

We use a Markov chain model to analyze the Korean Baseball League. We derive the distributions of the number of runs scored and the number of batters that complete their turn at bat in a baseball game using the time inhomogeneous Markov chain. The model is tested with real data produced from the 2011 Korean Baseball League.

The authors have treated 2 patients with submaxillary gland stones involving sialadenitis. The 2 cases were observed in the right submaxillary gland of 51 years old woman and left submaxillary gland of 54 years old man. The 2 patients with salivary stones were reated by toatal sialolithectomy and glandectomy. The enucleated sialolithes were 18㎜ x 12㎜ and 8㎜ x 6㎜ in size.

This is a report of two rare cases, that authors have experienced, one being four sialoliths within a wharton's duct, which is a relatively frequent site of sialolith, and the other a multiple occurrance of 16 sialoliths at the orifice of stensen's duct, which has very low frequency of sialolith occurance. Both pathosis were removed using transoral sialolithotomy.

Sialolithiasis is the most common disease caused by calculi in a salivary gland and its duct. The pain and swelling of salivary gland is a chief complaint of patients presenting. Most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and the sublingual gland. One giant sialolith is rarely reported, while the several cases of one or multiple sialolith in the submandibular gland have reported in the literatures. In this case, we have removed the sialolith in which perforated mouth floor along Wharton's duct and report it.

In this paper, we propose batting index prediction models of 2017. Due to the insufficiency of KBO pitchers data, batting index prediction models of 2016 has been developed based on elected eight batting index collecting the past three years data of MLB and KBO. It has been found that this prediction model fits well to both MLB and KBO, and the KBO model fits better than MLB in some cases. Using these prediction models, we analyzed and compared 2016's estimated values for the batting index of MLB and KBO. With the relation results between batting index prediction and batter's age for MLB and KBO, it can be determined that there is no relationship between the significant batting index and ages.

The resection of submandibular gland is usually performed via trascervical, transoral approach. The authors suspected the stenosis of Wharton's duct of 54 years old female patient after transoral removal of submandibular stone and the resection of submandibular gland was decided. Because of cosmetic need, the resection was performed transorally. The operation was completed successfully without any injury to unilateral lingual nerve or hypoglossal nerve but contralateral paralysis of hypoglossal nerve was seen. In our knowledge, this is the first report of contralateral hypoglossal nerve palsy during transoral resection of submandibular gland.
