Bilateral adrenal neoplasms are associated with metastatic cancer, pheochromocytoma and lymphoma. The coexistence of a unilateral functioning adrenocortical adenoma with contralateral pheochromocytoma is extremely rare. A 52-year-old woman complained of fatigue, headache, palpitation, and progressive weight gain. Hormonal assessment demonstrated high 24 hours urine epinephrine, norepinephrine, and free cortisol. A dexamethasone suppression test (overnight 1 mg, low dose 2 mg) showed insuppressible cortisol. Computerized tomographic scanning revealed a bilateral adrenal tumor. To preserve adrenal function, right adrenalectomy along with left adrenal tumorectomy was performed. Histological finding of the right adrenal tumor was pheochromocytoma and the left adrenal tumor was adrenocortical adenoma. This patient was the first case of a functional adrenocortical adenoma with contralateral cystic pheochromocytoma in Korea. We report the case with a review of the literature.

Purpose: To report optical coherence tomography (OCT) findings in albinism. Methods: Full ocular examinations, including OCT, were performed in one patient with ocular albinism and two patients with oculocutaneous albinism. Results: OCT scans were unable to detect the foveal depression in these patients. A widespread thickening of the retina occurred throughout the entire fovea, which showed no difference from the surrounding macula. OCT scans also demonstrated probable scleral layer below the retinal pigment epithelial (RPE) layer. Conclusions: OCT scans of albinism patients confirmed foveal hypoplasia and increased transmission of incident light in the RPE layer.

Recently, frequently using hyperbaric oxygen therapy is known for its effectiveness on the healing of problem wounds such as osteomyelitis, osteoradionecrosis and gas gangrenous wound etc. The main objectives of this study was to determine the best protocol of its application of hyperbaric oxygen therapy. Author used 238 rats (Sprague-Dawley strain) deviding into 2 Groups, experimental I group for skin and experimental II group for palatal mucosal inschemic wounds, and observed its effects by microscopically. The obtained results summarized as follows; 1. Severe infiltration of inflammatory cells was observed in initial stages of both control and experimental I group. The infiltration showed decreasing tendency at 5th day of experimental D, E, F group while at 8th day in control group In d, f of experimental II group showed decreasing tendency at 8th experimental day while at 12th day in control group. 2. Macrophages appeared at 2nd day in D of experimental I group while at 6th day in control group. In d, f of experimental II group appeared at 6th day while at 10th day in control group. 3. As to the proliferation of capillary blood vessels showed at 3-4 day in most of experimental I group severely while at 8th day in control group. In experimental II group, it was at 8th day and 12th day respectively. 4. The proliferation of fibroblasts showed rather rapider in experimental I group, at 4-6th day, while at 8th day in control group. In experimental II group, it was at 8th day and 12th day respectively. 5. As to the collagen formations, it was at 4th day in experimental I group while at 8th day in control group. In experimental II group, it was at 6th day and 10th day respectively. 6. 5 rats (2.0 %) in E group and 8 rats (3.4 %) in f group showed oxygen toxic reaction, such as unstable attitude and tremor, during the experiments. This hyperbaric oxygen animal experiments disclosed excellent effects on the ischemic wound healing and it is thought to be the best protocol of its application was on D group (2.5 ATM. and 2 hrs, exposure).

To enhance the speech recognition degree by computer, it is required to analyze the speech by the generation and sex. This study has surveyed most of the representation approaches to the speech analysis and selected RSSLS(recursive sample-selective least square), which is supposed to be the best method to the experiment. The purpose of the experiment is directed to extract the comparative statistics on the speech characteristics of the generation and sex.

The study examines the space composition and character of Mediaeval Theater of the middle ages focused on the theory of typology and interpreter in the european traditional classic theater. Contemporary multi purpose theater and public space is considered as a symbolic representation of the mediaeval theater's organization. In the historical theory, theater was a common tool and best system in reflecting people's live. This role of mediaeval theater as life cycle and new style of theater permanent design has get its value with the population increase and the urban centralization of the city and urban common sense. This study attempts to revaluate the need of space typology in modern society through a critical review of theater and its use as a open space. design.
동위원소희석 질량분석법에 의한 1000 ㎍/g 염소 표준용액 중 브롬 불순물 분석

The isotope dilution method was used for the determination of Br impurity in $1000{\mu}g/g$ Cl standard solution. Since relatively pure KCl salt was used for the preparation of the Cl standard solution, the Br impurity determination suffers from both spectral and non-spectral interferences due to the presence of a large amount of K and Cl matrices. AG2-X8 anion-exchange resin was employed to separate the Br analyte from the matrices, and RF power was raised to 1500 W and nebulizer gas flow rate was lowered to 0.77 L/min to reduce background from the $ArArH^+$ molecular ions. The Br impurity in the $1000{\mu}g/g$ Cl standard solution was determined to be 43.7 ng/g with the standard addition method. The analytical result was in good agreement with 41.2 ng/g (RSD 1.6%) determined by the isotope dilution method to lower uncertainty from poor reproducibility of the anion-exchange process.
