Throughout the twentieth century, American furniture was subject to a number of influences-both domestic and foreign. Especially, in the first half of the twentieth century, there were strong foreign influences compare to the later half of the century. Therefore, this study aimed for discussing foreign influences and for addressing issues such as attitudes toward materials, ornamentation, and technology. As a result, this study suggests how American furniture becomes instinctive moving away from strong foreign influences from the second half of the century. The twentieth century was a period of rapid and dynamic change for American furniture design. In many ways, the designs throughout the century were reflective of the social, political, and economic culture of the time. With the birth of the modern movement in Europe and a strong influx of foreign immigrants, American design in the first half of the century was characterized by a reliance on European and foreign influences. However, after the two world wars, strong domestic influences came into play. The two world wars provided the essential catalysts for change: new materials, developing technology, and changes in life style and consumer values. A historical examination of design trends and individual designers illustrates how American furniture design evolved during this period.

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease that behaves as a slowly expanding lesion with a gradual onset. It is well established that CEIH is associated with arteriovenous malformations; however, CEIH associated with cavernous malformation (CM) is extremely rare. We herein report a case of CEIH associated with CM, and discuss its pathogenesis. A 12-year-old female was admitted to our hospital because of a one week history of progressive headache and nausea. Brain computed tomography scan and magnetic resonance imaging showed an intracerebral hematoma surrounded by edema in the right frontal lobe. One week later, her headache and nausea worsened, and a brain computed tomography scan revealed the enlargement of hematoma. A right frontal craniotomy was performed. The capsule, mass, and hematoma were totally removed. Histological examination confirmed the diagnosis of CEIH associated with CM. Immunohistochemical analysis revealed increased expression of vascular endothelial growth factor (VEGF) and the VEGF receptor-1 in the endothelium and fibroblasts. Our findings suggest that the activated VEGF pathway might have positively contributed to development of CEIH in the present patient.

Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of the enzyme ${\alpha}-galactosidase$ A, resulting in the accumulation of glycosphingolipids within the lysosomes of various cell types. It has a wide spectrum of clinical phenotypes, and renal failure is a serious complication. Fabry disease is confirmed either by measurement of ${\alpha}-galactosidase$ A activity or by genetic testing for GLA mutations. Renal biopsy findings on light microscopy, specifically enlarged podocytes with foamy cytoplasm, and osmiophilic inclusion bodies in the cytoplasm in all types of renal cells on electron microscopy, are characteristic of this disease. The predominant differential diagnosis is iatrogenic phospholipidosis in association with certain drugs that can cause cellular injuries indistinguishable from Fabry disease. Here, we report the case of a 10-year-old boy with microscopic hematuria who underwent a renal biopsy that showed morphological findings consistent with Fabry disease, although the patient had neither a GLA mutation nor a history of drug consumption. Six years later, spontaneous regression of this renal pathology was observed in a second renal biopsy examination.

Beh,cet's disease was originally described as a triple symptom complex of oral aphthous ulceration, genital ulceration, and hypopyon iritis. It is now known to have a wide systemic manifestations. Among them, the central nervous system involvement should be diagnosed earlier because of it's lethal potential. Recently the authors experienced a case of Behcet's disease with CNS involvement. A 51-year-old female patient was admitted due to deterioration of mentality and generalized ache since 2 years prior to admission. The findings on physical examination were compatible with Behcet's disease, but without cerebrospinal pleocytosis. The manifestations were improved with medications of prednisolone, chlorambucil, colchicine, but relapsed 2 months later during subsequent tapering of prednisolone and chlorambucil. The patient is now on medication again. A case of Beh,cet's disease with CNS manifestations is reported with review of literature.

Spontaneous dissection of the anterior cerebral artery is an unusual cause of subarachnoid hemorrhage. We present a case of a dissecting aneurysm of the anterior cerebral artery presenting with subarachnoid hemorrhage. A 51-year-old woman presented to our hospital with severe headache. Neurological examination demonstrated neck stiffness, decreased visual acuity of the left eye, and left ankle weakness. Computed tomographic scans showed subarachnoid hemorrhage. The initial cerebral angiogram demonstrated a slightly narrowed caliber and mild poststenotic dilation of the right A1 segment. A second cerebral angiogram 14 days later revealed no change in the focal narrowing of the proximal A1 segment but marked progression of the dilatation of the distal A1 segment. Right pterional craniotomy was performed. A sausage-like dilation of the right A1 segment was found with no definite mural hematoma. This abnormal right A1 segment was wrapped with a Sundt clip. A postoperative computed tomographic scan revealed Infarction of the right head of the caudate nucleus and the anterior limb of the right internal capsule. If a dissecting aneurysm is suspected, serial angiographic studies should be performed because of the possibility of dynamic changes over a short period.

Objectives : Among the translations of the verse "Sa-gi is on the upper side, Tak-gi is on the middle side, Cheong-gi is on the under side(邪氣在上, 濁氣在中, 淸氣在下)" in the texts of Miraculous Pivot(靈樞) Nine needles and Twelve sources(九鍼十二原), the meanings of 'Ham-maek(陷脈)' and 'Joong-maek(中脈)' have contradictory versions. Methods : This study will identify the actual meaning of this verse through analysis of the phrase "夫氣之在脈也", followed by examination of the relationship between the meaning of "three-stratum puncture(三刺)" in the chapters Miraculous Pivot Handling needle(官鍼), Miraculous Pivot Jong-si(終始) and the meaning of "刺有三變" of Miraculous Pivot Longevity and character(壽夭剛柔), after which its application in later periods will be discussed. Results : The words 'Sa-gi', 'Tak-gi' and 'Cheong-gi' in the phrase "夫氣之在脈也" of Miraculous Pivot Nine needles and Twelve sources each correspond to the words 'yang pathogens(陽邪)', 'yin pathogens(陰邪)' and 'essence derived from food(穀氣)' of Miraculous Pivot 終始, respectively. Conclusions : The Upper-Middle-Lower of the phrase "夫氣之在脈也" in Nine needles and Twelve sources indicates the three levels of depth, in which 'Sa-gi', 'Tak-gi' and 'Cheong-gi' each dwell. 'Ham-maek' and 'Joong-maek' are categorizations according to the depth of needling.

Surface texturing of micro dimple or pore-shaped pattern was prepared using a fiber laser system. Surface texturing was designed to have a square pattern with a particular pitch distance for each corresponding density of 5, 10, 20, and 30%. Thermal damages such as bulges and burrs formed during laser irradiation were observed around the dimples. Thermal damages were later removed by lapping using alumina particles of $0.3{\mu}m$ in diameter. Oscillating friction tests were performed against heat-treated high speed steels under lubricated condition. The lubricant used was SAE 5W-30 automotive engine oil. Normal contact pressure and oscillating frequency was 0.28 MPa and 20 Hz, respectively. The tests were continued for 20 minutes, and friction plots were recorded for examination. Results revealed that the coefficient of friction was lowered regardless of texturing density. Moreover, the lowest coefficient of friction was obtained for 10% density texturing. It is attributed to increased lubricity due to the introduction of surface texturing. In addition, it is concluded that the optimum texturing density and pattern must be found for the best lubricity and low friction.

The purpose of this study is to investigation the eating habits and health-related behaviors of adolescent students. 700 students are randomly selected in 6 high schools in Chunchon area. The most students take three meals a day. but most of girl students take less two meals a day or often go without a meal. There are the tendency that boy-students are more satisfied with their meal habits, but they have the health problems caused by irregular meals. There are more boy-students have the regularity of meal habits than girl students. and the former have the more tendency of going without a meal than the later which shows that girl-students have to give more attention to their health management. Their sleeping hours are not enough to recover the tiredness. The higher grads they are in the less time they have to take a rest. The tenth grads students are shown to feel the most serious stress. but have few opportunities to take a medical examination, which means that we have insufficiency of health education as a precautionary measures. Accordingly, it is important that teachers have to provide students with education of good meal habit which is fit to their real life. In modern times, as there are the tendency that more women participate in the social activity. we will reinforce the education that the boy-students may take active part in the health management without distinction of the roles between boy and girls-students.

We describe the case of a 73 year-old female patient, YSG, who initially presented with a manic episode without any previous psychiatric history and was later diagnosed as having a meningioma in the left frontal lobe. YSG's symptoms were characterized by hyperactivity, insomnia, aggressive behavior with an auditory hallucination. She showed no abnormal signs on a complete neurologic examination. A gadolinium-enhanced MRI study showed a huge, extra-axial mass with homogenous enhancement in the left high convexity of the frontal lobe. Her manic symptoms subsided after administration of risperidone 1mg and valproic acid 500mg daily, for three weeks without surgical resection of the tumor. These findings suggest that YSG's mania might have resulted from the left-sided frontal tumor, and that her symptoms were treated rapidly by small doses of risperidone combined with valproic acid. Medical staff who care for manic patients should be aware of this possibility of a organic lesion without evidence of neurologic disease.

An 8-year-old castrated male Korean short hair cat was referred with chronic vomiting, diarrhea, and anorexia. The cat was diagnosed with alimentary lymphoma via fine needle aspiration. Three weeks later, he was presented again with anorexia. Hepatomegaly and hyperechoic change in the liver parenchyma were observed. Computed tomography while awake was performed and revealed hypoattenuation of the hepatic parenchyma. The cat was tentatively diagnosed with feline hepatic lipidosis secondary to alimentary lymphoma. In the feline patient with lymphoma, hepatomegaly is important to differentiate hepatic lipidosis from hepatic infiltration of lymphoma on liver. In the present case, fatty infiltration of the liver was identified via non-invasive, rapid, and convenient computed tomography examination in an awake cat with a lymphoma.
