Invasive pulmonary aspergillosis is a disease occuring predominantly in patients with defects in immunity such as neutropenia, hematologic malignancies or with defects in cell-mediated immunity. The isolation of Aspergillus from respiratory tract of normal host usually signifies tracheobronchial colonization, making this diagnosis difficult. There are isolated case reports occuring in normal hosts but most of them were diagnosed postmortem at autopsies indicating that early diagnosis of invasive aspergillosis in normal host is difficult. We describe here a case of invasive aspergillosis in a immunocompetent host diagnosed by lung biopsy which was successfully treated with Amphotericin-B. Invasive pulmonary aspergillosis should be included as one of the differential diagnosis if a patient with pneumonic consolidation does not respond to usual therapy, even if the patient does not have any defect in immunity.

In this study, the development of an aluminum forged piston was tried to substitute the cast piston, in which there were internal defects such as blow hole and shrink pipe. A gasoline engine piston was chosen as an example for developing the forged piston. Before aluminum forging, model, material (plasticine) test was carried out to investigate the forgeability and internal flow pattern of the forged piston at room temperature. From the result of model material test, an aluminum piston to be forged was redesigned. The aluminum pistion was forged in hot process. The quality of a forged piston was compared with that of a cast piston in the point of mechanical properties, internal defect and microstructure. It was proved that the forged piston was superior to the cast piston.

산업 현장에서 사용되는 배관이나 압력용기의 결함 검출은 시설의 안정적 운용에 기본적이며 중요한 문제이다. 전자 전단 간섭법은 결함 검출에 사용되고 있는 기존의 비 광학적 검사방법에 대한 여러 가지 장점들 뿐 만 아니라 전자 전단 간섭법 외의 다른 광학적 방법보다 외란에 둔감하여 산업 현장 적용성이 비교적 높다는 장점을 가지고 있다. 이에 본 논문의 전편 "전자 전단 간섭법을 이용한 압력용기의 내부결함 측정에 관한 연구(I)"에서는 압력 용기에 내부에 존재하는 결함을 검출하는데 전자 전단 간섭법을 적용하여 보았으며 결함부의 변형률을 3차원으로 가시화 하였다. 이에 더하여 본 논문에서는 전편에서 구성한 광학계를 바탕으로 결합의 길이를 구하고 결항의 조건과 가압력 등의 변화를 주어 시스템의 오차를 분석하고 그 측정한계를 규정하기 위한 실험을 수행하였다.

After researching on infantile diseases in Hyungsang medicine, the writer got the conclusions as follows. The infants who are excess of the Yang energy need to nourish the Eum- blood. The main causes of the infantile disorders are congenital defect and malfunction of internal organs by nature, as results of these they suffer from mental disorders or being undergrown. And after birth they get ill from internal injury or external affections, mainly epilepsy by retention of undigested food, fever, cough, asthma, nasal obstruction, dermatopathia, and affection by cold, etc. In Hyungsang medicine Dam-body is apt to get ill from deficiency of Eum-blood and bangkwang-body from deficiency of Yang-energy. And infants are hare to be moderate in food, so they become to diseases of the Spleen and stomach, especially infants with Yangmyung type get to epilepsy, cough, skin disorders, and obese for the reasonof overeating. Among main infantile symptoms congenital defects, infantile mental disorders, and convulsive diseases come from congenital defect and malfunciton of internal organs, so it must be treated the symptoms following the reasons. Above all infantile mental disorders are treated not to separate the spirit from the body. And fever, cough and asthma, affection by cold, skin diseases, poor appetite, and obese come from deficiency of Kidney or the deficiency and excess of the Spleen and stomach. In order to prevent from infantile diseases right antenatal training, taking medicine rightly, exercise and eating good habits are needed to give guidance. Seeing through the clinical cases in Hyungsang medicine, we come to know that the infantile mental disorders come out primarily for the reasons of the congenital defect, and the infantile epilepsy come from malfunction of internal organs, and the nasal obstruction and skin diseases come from deficiency of Kidney or the deficiency and excess of the Spleen and stomach.

In this study, multilayer piezoelectric actuators were fabricated with 75 layers by a conventional multi-layer capacitor (MLC) techniques, using 70Ag/30Pd paste as an internal electrode which can be sintered at low temperature and have cost down effect in mass productions. The multilayer piezoelectric actua-tors had no defects such as diffusions of internal electrode to ceramic bodies and shortages of internal electrodes. The multilayer piezoelectric actuators did not show the crack in the ceramics parts and the gapping phenomena in the external eletrodes when Ag paste was used as external electrodes. The multilayer piezoelectric actuators showed a maximum displacement of 4${\mu}{\textrm}{m}$ at 100V dc voltage and kept the maximum displacement constant for 300 seconds. The multilayer piezoelectric actuators showed good matching properties between ceramic bodies and AgPd internal electrodes. We confirmed the possibility of large-scaled production of the multilayer piezoelectric actuators with superior electrical properties and cost down effect using 70Ag/30Pd paste as an internal electrodes.

The posterior cerebral arteries supply the temporal and occipital lobes of the left cerebral hemisphere and the right hemisphere. Clinical symptoms associated with occlusion of the posterior cerebral artery are visual abnormalities including opposite visual field defects, hallucination, visual amnesia and a variety of other symptoms, including confusion, cognitive disorders, thalamic syndrome, Weber's syndrome, contralateral hemplegia. This case report is about a patient with visual and cognitive abnormalities caused by posterior cerebral artery infarction. He was regarded as Soyangin(少陽人) in constitution and was treated with Yangkyuksanhoa-tang(凉膈散火湯) and other treatments. Improvement in his general symptoms was observed.

Coronary vasospasm is one of the fatal complications that may occur in patients undergoing open heart surgery. To date, however, there are not many cases in this series and no definite pathophysiology has been documented. We experienced a case of coronary artery vasospasm after atrial septal defect (ASD) surgery and then successfully treated it with both transbrachial intraaortic balloon pump and percutaneous cardiopulmonary support. Only several hours after ASD surgery, the patient exhibited the cardiovascular collapse, the ST-segment elevation, followed by ventricular fibrillation and normal coronary angiography findings. It is important to make a differential diagnosis of coronary artery vasospasm in patients presenting with ST-segment elevation who had no notable coronary artery diseases. This case indicates that clinicians should be aware of the possibility that the coronary artery vasospasm may also occur in patients undergoing ASD surgery.
