A novel prototype of an inductive superconducting fault current limiter with an iron core and an air sap was fabricated and tested. If its impedance is not high enough to limit the fault current, then destructive damage occurs in the power system. We attained a magnetic saturation under the higher current by introducing an air gap in the three-legged magnetic core. The fault current was successfully limited to two times as much as the nominal current without high fault current within 1/4 cycles at a 60 Hz source having an effective voltage of 70V.

Acromegaly is a rare endocrine disorder caused by excessive secretion of the growth hormone. There is a wide range of clinical manifestations from somatic symptoms to respiratory or cardiac failure. Among them, cardiovascular involvement is a leading cause of morbidity and mortality. There are relatively few cases reporting cardiac magnetic resonance imaging (CMR) findings of cardiomyopathy in patients with acromegaly. Thus, we report a case of acromegaly showing dilated cardiomyopathy focusing on the findings of CMR.

In microfactory, loading/unloading mechanism supply the row material to processing machines for manufacturing process such as pressing, cutting, plastic deformation. This mechanism for rnicrofactory is designed as modularity robot. Microfactory system have to be flexible structure for variety product item. For system flexibility, applied mechanisms are developed as moduality. Robot moduality needs the specific characteristics which are different from one of macro, typical robot system. In this paper, we discussed about the modularity robot. and proposed the loading/unloading mechanism for working in microfactory system.

We explored the role of reactive oxygen species (ROS) in LPS-induced bone loss. LPS was shown to increase the concentration of ROS in osteoclast precursors. The antioxidant decreased osteoclast formation by LPS. Furthermore, the antioxidant decreased NFATc1 expression by LPS, suggesting that ROS mediates NFATc1 expression in the regulation of LPS-induced osteoclast formation. Finally, the antioxidant decreased LPS-induced RANKL mRNA expression in osteoblasts. Taken together, these data indicate that LPS mediates ROS to induce bone loss.

The purpose of this study was to investigate the differences of sports involvement and consumer attitude on fashion advertisement using sports star models(CAATTM) according to demographics and to investigate the effect of sports involvement to CAATTM. The subjects selected for final analysis were 398 adults living in Daejeon. The statistics used for analysis included factor analysis, ANOVA, multiple range test, regression, $Cronbach'\alpha$, and frequency. The results were as follow: 1. Sports Involvement was divided Cognitive Sports Involvement(CSI) and Emotional Sports Involvement(ESI). The CSI and ESI were different according to sex. And CSI was different according to age, education level and marriage status. 2. CATTM was divided into three factors: Emotional Attitude(EA), Cogitive Attitude(CA), and Ethical Attitude(ETA). CA was different according to sex, age, income, and marriage status. 3. The sports involvement affected CAATTM. People who were high in CSI and ESI showed high attitude in EA and CA.

This paper presents a simple but valid loss calculation method of grid-connected photovoltaic system based on normalized yield model. The proposed method can be represented as a quantitative value for five losses and performance of grid-connected photovoltaic system with three years monitored data. These results will indicate that it is useful to investigate various loss factors causing the performance obstruction, enhance the lifetime yield for changing meteorological conditions, and determine the optimal design and performance improvement of grid-connected photovoltaic system.

The definition and application of disability are becoming more important as society becomes more complex. The precise criteria for the assessment and classification of disabilities are primarily focused on certain medical conditions with a lack of guidelines for dental conditions. This study provides an evaluation and comparison of the current tables available for the assessment of disabilities in the dental field with the aim of identifying areas to be improved.

Objective: The objective of this study is to observe the effect of anti-inflammatory herbal acupuncture on the Supraspinatus Tendinosis and subdeltoid bursitis Methods : Anti-inflammatory herbal acupuncture, A-Shi Point, Sa-am acupunture were used to treat shoulder pain. We evaluated the patient through VAS(Visual Analog Scale) daily and Physical Examinations Results & Conclusions : After 12 days of treatment, shoulder pain was decreased from VAS9 to VAS1 and the patient showed nearly full ROM(range of movement). In shoulder pain, oriental treatment is good method for pain relief and better movement.
