This research how self-esteem and consumption behavior for adolescent consumers are differentiated different psychological home environment and how the psychological home environment during adolescence self-esteem and consumption behavior. The result of the research as follows. First, when the psychological home environment categorized in 4 subgroups, accomplishment-non-accomplishment zone had average 3 points sense of non-accomplishment. Setting the aspiration level and striving to achieve such level were reviewed to be low. In autonomous-heteronomous, it is thought that with more allowance more responsible for actions and autonomous actions such as respecting personal opinions. Secondly, all 5 sub-groups of the self-esteem level for adolescent consumers showed average of approximately 3 points, a normal standard self-esteem When the overall school score is high self-esteem was also given high points. It can be thought that the school scores provide positive or negative effect on pride, future and surrounding situations. When psychological home environment was deemed positive in the relationship between psychological home environment and self-esteem, evaluation and the faith how other people recognize one were also thought positively. Thirdly, 4 subgroups of the consuming behavior for adolescent consumers had under 3 points for trend pursuit, showing a less severe trend pursuit by adolescents then expected. Consumer behavior for different psychological home environment and self-esteem showed that consumers selected a utility, while trendy and unique consumer behavior was found with middle level of open-closeness when a sense of accomplishment was significant among the psychological home environment.

Ovarian cancer is common malignant disease with high mortality in the female. However, lymph node metastasis in the head and neck of ovarian cancer is very rare than in para-aortic, pelvic lymph node. A 49-year-old female patient came to our clinic with a left neck mass. After total thyroidectomy and left selective neck dissection for the cervical neck level II, III, IV, V, VI for ovarian cancer and thyroid cancer, she had already undergone chemotherapy (Paclitaxel+Carboplatin) 18 month ago. CT scan showed only lymph node enlargement in left neck level II. Positron emission tomography-computed tomography (PET-CT) revealed a hypermetabolic lesion in same area but no other hypermetabolic lesion, especially in the pelvic and abdominal cavity. Fine needle aspiration cytology revealed metastatic carcinoma. The serum level of CA-125 was elevated to 43.8U/mL, whereas other tumor markers (CA 19-9, CEA) were in the normal range. She underwent a revision of selective neck lymph node dissection for the cervical neck levels I, II, and III, and on the review of surgical pathology, metastatic carcinoma was suspected. Thus, we performed immunohistochemical staining for the tissue; as a result, it was finally diagnosed as metastatic ovarian cancer (positive for CK7, ER and PR, and negative for CK20). Adjuvant chemotherapy (Paclitaxel+Carboplatin) was planned on the tumor board, and the patient successfully received chemotherapy.

Milk-alkali syndrome (MAS), a triad of hypercalcemia, metabolic alkalosis, and renal failure, is associated with ingestion of large amounts of calcium and absorbable alkali. MAS is the third most common cause of hypercalcemia in hospital, after primary hyperparathyroidism and malignant neoplasm. MAS is not often reported in the Korean literature. We describe MAS secondary to intake of calcium citrate for the treatment of osteoporosis with thoracic spine compression fracture. A 70-year-old man presented to our hospital with a 1-week history of general weakness and lethargy. He was found with acute kidney injury (serum creatinine, 4.6 mg/dL), hypercalcemia (total calcium, 14.8 mg/dL), and alkalosis. Laboratory evaluation excluded both hyperparathyroidism and malignancy. Mental status and serum calcium level was normalized within a week after proper hydration and intravenous administration of furosemide. However, he developed aspiration pneumonia, pseudomembranous colitis, and sepsis with multi-organ failure. Despite intensive treatment including inotropics, mechanical ventilation, and renal replacement therapy, he expired with no signs of renal recovery on the 28th hospital day.

Chordoma is relatively uncommon tumor comprising $1\sim4%$ of primary malignant bone tumors, and believed to arise from the remnants of notochordal tissue. Because of its rare occurrence in the thoracic spine, we report a case of chordoma involving the thoracic spine. A 45-year-old male was sufferred from chest pain radiating to the back. Chest CT showed a well marginated, round huge mass with multiseptated enhancement at the thoracic spine from T5 to T8 level. After percutaneous needle aspiration, piecemeal resection of the tumor was done. On cytologic smears, two types of neoplastic cells were arranged in sheets and cords in mucinous background. One type of cells consisted of medium sized cells with pink cytoplasm and round nuclei. The other type had voluminous bubbly or clear cytoplasm divided by intracytoplasmic septae imparting a feathery or basket-like appearance. Histologically, the tumor showed lobulated feature divided by fibrous septae and the tumor cells were pink eosinophilic or physaliphorous in morphology. Immunohistochemically, the tumor cells revealed strong positivity for low(AE1) and high (AE3) molecular weight cytokeratins.

Automobile maneuverability and tire durability are significantly influenced by the sidewall tire contour. In order to improve these tire performances, it is very important far one to determine a sidewall contour producing the ideal tension and strain-energy distributions. However, these requirements can nut be simultaneously achieved by conventional non-interactive multi-objective optimization methods based on mathematical programming, because these exhibit the conflicting behavior each other, with respect lo the sidewall contour. Therefore, we execute the tire contour optimization fur improving the maneuverability and the tire durability using satisficing trade-off method.

A 62-year-old female patient had goiter for twenty years. She visited out-patient clinic with a hoarse voice and intermittent breathing difficulties. About protruding 15cm sized mass located the anterior neck and right vocal cord paralysis was observed. Preoperative CT scan was strongly suspected of thyroid gland cancer and cervical lymph node metastasis. Therefore, fine needle aspiration test was performed and surgical treatment was planned with the histopathologic results (papillary thyroid carcinoma). Surgery was performed with total thyroidectomy, bilateral cervical lymph node dissection, and right selective nodal lymph node dissection (level II-V). During operation right thyroid seemed to be adherent to surrounding tissue and the blood vessels were extremely engorged. There was hypotensive crisis because of intraoperative excessive bleeding. However it was managed by repetitive transfusion. The operation was completed without abnormalities. She underwent 4 times of bleeding control operation due to postoperative bleeding. After complications were improved, we are currently undergoing out-patient follow up without morbidity.
