A 78-year-old woman was referred to Chonbuk National University Dental Hospital complaining of facial palsy and palpable mass on the right parotid gland area. Clinical examination showed non-specific findings of the intraoral region, but showed asymmetrical facial appearance. Panoramic view showed a large amorphous calcified mass on the posterior to the mandibular ramus and thin cortical plate of the posterior ramus. Sialogram showed constriction of the main duct and no further filling of striated, intercalated ducts and parenchymal areas. CT scans demonstrated an irregular, infiltrating mass with slight enhancement in the right parotid gland. The mass showed necrotic areas and calcifications. Bone scan showed marked accumulation of /sup 99m/Tc-MDP on the right posterior maxilla. Microscopic findings demonstrated the minimal morphologic alterations and rare mitotic figures within tumor cells, and diagnosed as adenocarcinoma (NOS, Grade II). This report could be aid in the diagnosis of calcified lesions of the salivary gland.

Cystic lymphangioma is an uncommon benign developmental tumor of the lymphatic system, seen rarely in adults. A 23-year-old man visited DKUDH complaining of the painless swelling in the right submandibular area. It was reported that swelling had increased since 5 months ago. Clinically, fltriangle uctuant and mobile mass was palpated at the right submandibular area. CT scan showed a large, well-defined, homogenous low density mass, measuring 5.0 × 2.5 × 4.0 cm. T1W MRI scan demonstrated a large, multiseptated homogenous low signal mass with septum and rim enhancement. Proton-density and T2W MRI scan showed mass of high signal intensity. MRI scan was able to delineate better the enhanced multi septation and extent of the lesion. Histopathologically, a lobulated cystic mass lined by a layer of flattened endothelium was observed.

This study was administered to demonstrate how unsatisfied customers would be influenced by the change in the quality of the service delivered to them after the dissatisfaction occurs. In light of the above, the objective of this study is to find out what leads to dissatisfaction in the minds of the consumers and also to identify the common behavioral patterns indicated by unsatisfied consumers. This study consists of two parts: a research based on the review of the literature and empirical study methods. As a result, a research for the popular forms of complaining patterns shows opportunities for restaurants to come up with measures to improve their service quality when customers are unsatisfied. In service recovery situation, distributive and interactional justice significantly influence customers' repurchase. Therefore, firms ought to offer monetary compensation, explain about the problems, and make their best efforts to recover the failure because the efforts also affect repurchase.

A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.

Rock fragmentation with plasma blasting technique has advantageous properties in contrast to the conventional blasting method controlling of flying rocks and ground vibrations, when residents are complaining or surrounding structures stay in protection from blasting operations. The experiences show in urban construction works that the plasma blasting is the most possible method to prevent damages and minimize adverse environmental impacts. The fragmentation energy level is evaluated by numerical simulation using PFC for various drill hole patterns and tested accordingly to get the feasibility. The energy output of plasma blasting system has been improved to a level of 1 MJ, which can break a 2-3 ㎥ granite boulder or 1.5m height bench face. Measurements are carried out to get the ground vibration level and propagation equation, so that control of the blasting operations can be performed more precisely and safely.

Angiomyolipoma(AML) of the liver is a rare benign tumor; about 50 cases, almost solitary, have been reported. We present here a extremely rare case of multiple AML in the liver diagnosed by fine needle aspiration cytology(FNAC). Two large masses were found in a 51 year-old woman complaining of abdominal discomfort by computed tomography and several smaller masses are scattered in the liver. FNAC was performed, showing bundles of spindle shaped smooth muscle cells intermingled with mature fat cells. FNAC may be a valuable method for definitive diagnosis of hepatic AML. The diagnosis was further confirmed by histologic examination with immunohistochemical studies.

Vaginal dryness is not a rare complaint of postmenopausal women. But the concerns and treatments about this were negative in patients and doctors. So we treated with Gagam-chungsimyeonjaeum(加減淸心蓮子飮) on three cases complaining vaginal dryness. As a result vaginal dryness was improved in all cases. Through this case report, we expect that more interests and participations in vaginal dryness will be got more qualities in life of postmenopausal women.

In a service business, it is difficult to cope with all your customers' needs. They come and go with various wants and when it comes to their own good there are complaining. Such variances in the service business interfere the operation resulting in inefficiency. To come against all those fluctuate wants, Frei is suggesting a new way how to cope with this customer variability in the service business: Low-Cost accommodation and uncompromised reduction. However, his assertion that these solutions can reduce cost and enhance service quality at the same time is empirically not proved. Thus, the following research will be dedicated in the empirical proof whether the solutions mentioned above can enhance service quality while reducing cost by pursuing efficiency in the service business.

We report a case of gastric pseudoterranoviasis proven by gastrofiberscopy on Dec. 13, 1994. The 34-year-old male patient, residing in Chungju-shi, was admitted to Konkuk University Hospital complaining of prickling epigastric pain. The symptoms suddenly attacked him two days after eating raw marine fish at Chonan-shi. By the gastrofiberscopic examination, a long white-yellowish nematode was found from the fundus region of stomach. The worm was $34.50{\;}{\times}{\;}0.84{\;}{\;}mm$ in size. and was identified as a 3rd stage larva of Pseudoterranova decipiens judging from the position of the intestinal cecum. This is the 12th confirmed case of human pseudoterranoviasis in Korea.
