As people's interest in functional foods has been rising, they began to be concerned about their salt consumption. In this respect, this research investigates the quality characteristics of bread added with various kinds of solar salt, and the stickiness, fermentation rates, pH levels, TPA, crumbScan and sensory evaluation of the dough were analyzed. For the stickiness of the dough, FSB had the highest stickiness. Also, NSB had the highest fermentation rate and fermentation persistence. TPA analysis showed that KSB had the lowest hardness and the highest springiness of all. According to crumbScan, KSB had the lowest crumb fineness, but there were no significant differences among the samples. Preference test showed that NSB got the best color, texture, flavor and taste. In overall acceptance, NSB scored the highest points, showing no significant difference with KSB.

Chylothorax is denned by extravasation of the milky fluid to pleural cavity from the thoracic duct or it's main branches due to operative trauma, congenital lesions, diagnostic procedures, tumor, etc. Another rare cause is diffuse pulmonary Iymphangiomatosis which is uncommon and not well charact rized. We experienced a case of the bilateral chylothorax caused by the diffuse pulmonary Iymphangiomatosis. The patient was at years old girl with symptoms of coughing and febrile sensation, and the chest radiographs showed bilateral pleural effusion and interstitial infiltrates. The laboratory data of the pleural effusion was identified as chile. Uncontrollable with closed tube thoracostomy, division of tHe thoracic duct and biopsy were decided. Biopsy showed anastomosing endothelial lined spaces along the pulmonary Iymphatic routes especially in pleural and interlobar septum, and smooth muscle at the proliferative interstitium of the Iymphatic duct was observed. Postoperatively, chylothorax was controlled with several trial of chemical pleurodesis. Af'leer discharge from the hospital, she was well for ten months follow up.

The defects of rail head induced by fatigue and deterioration are mainly classified by two types ; one occurred on the surface of rail head the another occurred on the inner rail head. This study performed the surface irregularity measurement of rail head according to the passing tonnage in the urban railway. Also, we carried out microscopic structure test, chemical component test and micro-hardness test for the specimen which is the used rail on metro line by accumulated passing tonnage. As a result of this study, for new rail, it should be performed initial grinding in order to remove 0.3mm of de-carbonized layer. The preventive-cyclic grinding for preventing RCF defects is proposed two options : grinding by the whole line and grinding by specified sections.

To determine freshness and quality change of tofu during storage, we manufactured a freshness indicator and monitored the surface pH, volatile basic nitrogen (VBN), thiobarbituric acid reacted substance (TBARS), total bacterial counts, and sensory evaluation. Tofu had a change in color of the freshness indicator after storage of 8 days at $4^{\circ}C$, and its pH and total bacterial counts reached 5.6 and 7.63 log CFU/g, respectively. VBN and TBARS values increased and reached the decay point at the time of color change of the freshness indicator. Sensory evaluation also indicated that samples were unacceptable by off-odor and decrease of firmness at day 8 of storage. These results suggest that a freshness indicator should be useful in determining expiration date of tofu products during marketing by indicating the microbial safety as well as sensory change.

Since the 1980s, there have been many research activities devoted to quantitatively characterizing and imaging human tissues based on sound speed, attenuation coefficient, density, nonlinear B/A parameter, etc., but those efforts have not yet reached the stage of commercialization. However, a new imaging technology termed elastography, which was proposed in the early 1980s, has recently been implemented in commercial clinical ultrasound scanners, and is now being used to diagnose prostates, breasts, thyroids, livers, blood vessels, etc., more quantitatively as a complementary adjunct modality to the conventional B-mode imaging. The purpose of this article is to introduce and review various elastographic algorithms for use in quasistatic or static compression type elasticity imaging modes. Most of the algorithms are based on the crosscorrelation or autocorrelation function methods, and the fundamental difference is that the time shift is estimated by changing the lag variable in the former, while it is directly obtained from the phase shift at a fixed lag in the latter.

Hepatocellular carcinoma is one of the most common cancers worldwide. Extrahepatic metastasis commonly occur in the lung, lymph, nodes, bone, and adrenal glands. On the other hand, a metastasis of hepatocellular carcinoma to the skeletal muscle is rare. A 42-year-old woman presented for evaluation of a palpable mass with tenderness in her right thigh area. She has been diagnosed with hepatocellular carcinoma and pulmonary metastasis seven years ago and has received treatment. We performed incisional biopsy with suspicion of hepatocellular carcinoma metastasis from imaging studies and blood test results. The patient was finally diagnosed with metastasis of hepatocellular carcinoma in the semimembranosus muscle and treated by extensive resection. We report this case with a review of the relevant literature.

The mediastinum is the most prevalent site of extragonadal teratomas. Patients with mediastinal mature teratomas are usually young adults, and the condition does not show significant sexual differences. Mediastinal teratomas are mostly located in the anterior mediastinum. Patients are usually asymptomatic, although they can have several complications when the teratomas become large or rupture. Most mediastinal teratomas can be diagnosed using CT. Diagnosing ruptured or malignant teratomas is challenging because of their atypical clinical and radiological presentations. In this article, we describe various manifestations of mediastinal teratomas, with an emphasis on radiologic features.

Injeulmi(Korean glutinous rice cake) was prepared without, 5, 10 and 15% of macerated tea leaves for utilizing unplucked low-graded tea leaves. The effect of firming rate by addition of tea leaf was determined using the Avrami's equation in terms of the texture parameters. Hardness of 5, 10 and 15% addition as compared with no addition was decreased gradually. Overall texture was softened in proportion to Increasing the content of added tea leaf and the addition of 5% and 10% were evaluated as the highest score as an acceptable sensory quality. Avrami exponents and time constant obtained from the Avrami's equation applicable for changes in hardness of without and 10% addition during 7days of storage at $20^{\circ}C$, $90{\sim}95%$ RH indicated 1.062, 15.3 and 0.989, 41.6, respectively, as showing the effect of delay on firming rate.

An ameloblastic carcinoma is a very rare odontogenic malignant tumor, which sometimes have a benign clinical nature, but typically have aggressive features, with large ulcerative lesion and extensive local destruction. These clinical characteristics make the complete surgical removal of a tumor difficult. As a consequence, a poor prognosis may result due to local recurrence and distant metastasis. For this reason, it is important to consider adjuvant therapies for high-risk ameloblastic carcinoma patients. Here, the case of a recurrent ameloblastic carcinoma that occurred in the mandible after primary surgery is reported. The lesion was treated with further local excision, followed by postoperative radiotherapy. Also, a few remarks on the role of postoperative radiotherapy in patient with ameloblastic carcinoma have been made from a review of the current literatures on the treatment of this type of lesion.

Pulmonary aspergilloma usually arises in preexisting lung cavities characterized by recurrent hemoptysis. Although surgical resection of the aspergilloma is the best treatment, most patients are poor candidates for surgery because of far-advanced underlying pulmonary disease. On the other hand, pulmonary actinomycosis is a chronic, indolent bacterial infection and follows aspiration of oropharyngeal material. Bronchiectasis and obstructive lung disease are often associated underlying conditions. We report a case of pulmonary aspergilloma in bronchogenic cyst associated with an actinomycosis in 21-year-old woman treated by thoracoscopic surgery with a review of literature.
