PURPOSE: Purpose :To evaluate the position and transverse dimension of the adult optic chiasm in normal Korean adult. MATERIALS AND METHODS: The authors analysed 3D coronal volume images (TR/TE= 30/13, flip angle= 30 degrees) of 136 normal adult subjects without known visual abnormality. All MRI examinations were performed using a 0.5T system. MRI was reviewed retrospectively to determine the position (horizontal and tilted) of the potic chiosm and the transverse dimension of the optic chiasm was measured. RESULTS: Seventy-five (55%) of 136 normal subjects had horizontal position, and sixty-one (45%) had tilted position. Thirty-eight (62%) of 61 with tilted position showed higher position on the right side, and twenty-three (38%) showed higher position on the side. The average transverse dimension(mean SD) was 15.2 +/- 0.7mm in men and 14.6 +/- 1.0mm in women. The difference of transverse dimension between men and women was statistically significant. CONCLUSION: Tilted position of the adult optic chiasm on coronal MRI was seen in approximately half of normal adults. The average of transverse dimension of normal optic chiasm was 15mm.

PURPOSE: This study aimed to investigate the job stress level of call center workers and figure out its relation with cognitive emotion regulation strategies as a cognitive coping strategy. METHODS: Data collection was conducted on 985 call center workers, working for K companies in Korea. ANOVA, t-test, Scheffe's test and multiple regression have been conducted for the data analysis using SAS 9.0 software. RESULTS: The total job stress score of subjects ranges Q25~49 (the lower 50%) whereas the score of job demand and job control ranges Q50~74 (the upper 50%), and its sectional job stress level is high. Since job stress is the major factor affecting cognitive emotion regulation strategies, it is shown that when the job stress score gets higher, the score of positive cognitive emotion regulation strategies gets decreased but the score of negative cognitive emotion regulation strategies, increased. CONCLUSION: Based on the results of this study, it is necessary to develop and apply an effective stress easing method for call center workers which reduces negative cognitive emotion regulation strategies and increases positive ones.

Multicystic ovary was first described by Silver in 1958 as a rare case feature of acquired primary hypothyroidism. In 1980, Lindsay reported four girls with hypothyroidism associated with multicystic ovary diagnosed by pelvic ultrasonography. The mechanism of ovarian cyst formation and pseudoprecocious puberty in severe hypothyroidism in childhood are unknown. Increased ovarian sensitivity to GnRH and increased TSH level which acts on FSH receptor is one of the mechanism explained. We report a case of a girl with primary hypothyroidism presented with pseudoprecocious puberty and giant follicular ovarian cyst with torsion.

Secondary ischemic necrosis of femoral head due to loss of blood supply following to femoral neck fracture is well known. The regional distribution of bone.seeking radiopharmaceuricals in the skeleton can depend on a number of facto rs, but bone blood flow is a major physiological determinant of regional skeletal uptake of Tc-99m polyphosphate and bone imaging may thus be used for the evaluation of vascularity of the femoral head. The authors made a comparative study of scintigraphic findings and operative findings of 28 cases of femoral neck fracture treated at Kyung Hee University Hospital from April ′80 to May ′84. The results were as follows: 1. In 16 cases of proven avscular necrosis of femoral head, scintigraphy showed absent or decreased activity in 14 cases (87.5%), while radiography showed increased density in 10 cases (62.5%). 2. In 12 cases of proven vital femoral head, scintigraphy showed increased activity in 9 cases (75%) and radiography showed decreased density in 9 cases (75%). 3. 99mTc-MDP scintigraphy was an excellent and useful method for assessing bone vitality of femoral head.

Most neonatal cutaneous hemangiomatosis are complicated by visceral involvement and. are associated with a high mortality rate in the first month of life. Some neonates with multiple cutaneous hemangiomas, however, may follow a benign course of spontaneous resolution without visceral involvement. Such cases are called benign neonatal hemangiomatosis (BNH). BNH is characterized by a lack of mucosal or symptomatic visceral involvement. rapid spontaneous regression of cutaneous hemangimas, and an excellent prognosis. We report herein a case of BNH which is atypical compared to previously reported BNFI cases. Our patient had a more prolonged course than those of usual cases with BNH and showed a conjunctival involvement.

Dariers disease is a domirantly inherited skin disease that is characterized by keratotic papules predominantly on the sebornieic areas, palmar pits, and a nail dystrophy. The diagnosis is difficult in the small group with flexural involvement because the features of flexural Dariers disease overlap clinically and histolopica.lly with those of Hailey-Hailey disease. The diagnosis of Dariers disease may be confirmed if the patient has the pathognomonic nail dystrophy. We presents a case of flexured. Dariers disease in a 65 year old woman. She has suffered from skin lesions which have some resemblance to those of Hailey-Hailey disease. We could diagnose her skin lesions as Dariers disease because she had the eharacteristic nail dystrophy.
