A solid-state energy storage device has been fabricated using FeCo-selenide nanosheet arrays as positive electrode and Fe2O3 nanorod as negative electrode. As an electrode material, the ternary FeCo-selenide nanosheet arrays supported by Ni foam show a highest specific capacitance of 978 F/g (specific capacity of 163 mAh/g) at 1 A/g and a superior cycle behavior of 81.2% are obtained after 5000 cycles at current density of 4 A/g. The asymmetric supercapacitor achieves the maximum energy density of 34.6Wh/kg at the power density of 759.6 W/kg. Furthermore, the superior cycling stability with 83% retention of initial capacitance after 5000 cycles further verify the practical applications of FeCo-selenide//Fe2O3 asymmetric supercapacitor. Meanwhile, the LED bulb and the light board of "CUMT" are lighted by connecting several capacitors to form a series circuit.

Effects of Chitosan Intake on Bone Mass, Bone Related Metabolic Markers in Ovariectomized Rats

Jang, Ye Sun,Lee, Myoung Hee 제주관광대학 2005 論文集 Vol.11 No.-

In the present study we examined both the etiology of bone loss induced by dietary chitosan and the preventive effect of vitamin C supplementation. Rats were OVX and maintained on one of the following diets for 4 weeks: 10% cellulose (CE), 10% chitosan (CH) and 10% chitosan with sodium ascorbate (CHVC). Vitamin C supplementation to CH caused an increase in Ca and P contents of femurs as well as BMD of L4, with a decrease in urinary Ca excretion. There was no significant difference in intestinal Ca absorption between CH and CE, whereas CH intake significantly reduced intestinal P absorption. CH caused a significant reduction in BMD and stiffness of femurs as well as fourth lumbar vertebrae (L4). The bone loss in CH rats was accompanied with an increase in urinary Ca excretion and a decrease in serum Ca as well as a significant increment in serum PTH and 1,25(OH)2D3. These results indicates that dietary chitosan with low Ca intake possibly induces the loss of bone mass by enhacing urinary Ca excretion, rather than by inhibiting Ca absorption, and that vitamin C supplementation could prevent bone loss caused by chitosan through the increment of retained Ca followed by suppression of urinary Ca excretion.

Exercise-induced anaphylaxis(EIA) is a medical emergency in that it derives from a physical allergy. We reported a case of food-independent EIA based on history and laboratory data. A 40-year-old male patient was presented with generalized urticaria, angioedema, and syncope after jogging. He had suffered from allergic rhinitis for 25 years. Increased level of serum tryptase was noted. Mast cell activation might be suggested in the pathophysiologic mechanism of EIA. (J Asthma Allergy Clin Immunol 24 : 152-5, 2004)

1980년대 한국 춤의 양상과 한계 : 민족 민중 춤과 포스트모더니즘 댄스를 중심으로 Focusing on the National and People's Dance and Postmodern Dance

이예순,강미선 韓國體育大學校 1995 論文集 Vol.18 No.-

It is hard to make a simple definition on Korean dance during 1980's. It can be divided in two groups, however. One is the National and People's Dance which recognizes dancing as a part of political, social and historical life, and raises a protest with collective message against rigid regime demonstrating ideology. The other is so-called Postmodern Dance, a liberal on which started before during 1980's and has argued a non-formal form escaping from existing cognition. This took a role to dismentle the established freame of dancing like Korean folk festival and encouraged an open attitude for dance itself. In the dancing environment during 1980's, it is also difficult to separate and approach to the two sorts of dance, which have a probability to be related each other. One of the reasons is that the structure of our politic, economy and culture exists in a great and confused mass, and that there are many complex streams in Korea and most of them are not arranged or remain not to decide their direction to unify. In short, our dancing culture is in a condition not to be mature for the structure between National and People's and Postmodern Dances. The activities of National and People's Dance during 1980's were by several groups, but they neither made a great result in dieology of creativeness nor had relationship or supplement with the existed dancing groups or Postmodern Dance. On the contrary, though the creative dances of Postmodern Dance showed a completedness. It is also true that Korean dance 1980's was afflicted with various problems such as harmonious endevour or development to re-creation on the threshold between tradition and modernity. It is necessary, therefore, to study and effort hard for the dance's participation in reality that is of delemas for contemporary man, or for making dance a common life, and these are the tasks for future Korean dance.

The purpose of this study is to identify effectiveness of MedX Exercise Machine being developed for reinforcing lumbar muscular strength of patients with lumbago through conducting 8 weeks of exercise by applying above-mentioned machine. Subjects of this study were a total of 30 people composed of a group of lumbago patients (15 persons) who had no operation and a group of lumbago patients (15 persons) who had operation subjected to MedX Exercise at U vertebra health research institute in Seoul. The tool of experiment was MedX Lumbar Extension Machine (MedX, Ocala, FL USA) and by means of this machine test was conducted by computing strength at tip of joint movement range with test angle between indentation of lumbar with no contraction of 72° - 0° (7 angles) standardized. In the course of extension test for lumbar with no contraction bar graph was produced by plotting muscular power of patients and secondary curves were produced by computer. The patients tested were subjected to an exercise program of 8 weeks with 3 times a week and 2 hours a session regime and the dates for exercise were fixed on Monday, Wednesday and Friday. Exercise was performed some time between 14:00 - 18:00 without fixed schedule. In general under the principle of therapy for curing paints Alpha Massage (johnson & johnson. USA) for treating heat on body surface was performed for 20 minutes thermally (36.7°C) prior to MedX Exercise and thereafter conducted light aerobic exercise for 45 minutes with 15 minutes session and carried out MedX Exercise for 30 minutes. As a winding up exercise cold therapy (18.3°C) was performed for 20 minutes. MedX Exercise for reinforcing lumbar muscular strength was conducted two 2 sets of 10-12 times with 15 minutes session and recorded that it improved muscular strength of the subject patients. In the course of conduction MedX Lumbar Extention Test the section of 0° - 72° was divided into 7 subsections (72°, 62°, 48°, 36°, 24°, 12°, 0°) and patients were made to generate maximum muscular strength for 2 seconds respectively. In the course of test for the purpose of strengthing lumbar muscular strength measurements were taken for 2 times in total before the exercise and after exercise for 8 weeks. Main results were 1. There was considerable increase in lumbar muscular strength because prior to starting exercise it was 796.5ft-lbs but after 8 weeks from exercise this figure was 1251.8ft-lbs (p<0.01). 2. It was shown that lumbago patients who had not operation (485.8ft-lbs) have higher level of improvement in muscular strength compared to lumbago patients who had operation (424.8ft-lbs). From the result mentioned above it was possible to draw a conclusion that by means of MedX Exercise considerable improvement of lumbar muscular strength is possible and therapeutic exercise substantiated by scientific method is effective and suitable to prevention and treatment of lumbago.

A bioequivalence study of Roxithrin™ tablet (Kukje Pharma. Ind. Co., Ltd.) to Rulid™ tablet (Han Dok Pharma. Ind. Co., Ltd.) was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty four healthy male Korean volunteers received each medicine at the roxithromycin dose of 300 mg in a 2×2 crossover study. There was a one-week wash-out period between the doses. Plasma concentrations of roxithromycin were monitored by a high-performance liquid chromatography for over a period of 36 hours after drug administration. AUC, (the area under the plasma concentration-time curve from time zero to 36 hr) was calculated by the linear trapezoidal rule method. C_(max) (maximum plasma drug concentration) and T_(max) (time to reach C_(max)) were compiled from the plasma concentration-time data. Analysis of variance was carried out using logarithmically transformed AUC, and C_(max). No significant sequence effect was found for all of the bioavailability parameters indicating that the cross-over design was properly performed. The 90% confidence intervals of the AUC, ratio and the C_(max) ratio for Roxithrin™/Rulid™ were 1.00 - 1.13 and 0.98 - 1.10, respectively. These values were within the acceptable bioequivalence intervals of 0.80 - 1.25. Thus, our study demonstrated the bioequivalence of Roxithrin™ and Rulid™ with respect to the rate and extent of absorption.

한국 전통색채를 활용한 한과류 패키지디자인 연구

Tdentity' is one of the main interests of today's post-industrial society. In other words, identity is the most important driving force in the 21st century. As new key words like Knowledge, Creativity and Culture along with Digital markedly stand out, the identity of ego is emphasized as a preferential competitive factor in this Informationization Age. When identity is applied to design, it creates cases and currents in which, starting from native designs, a design without its own identity loses its competitiveness, while the one with its identity and history leads the way in the world markets as a high value-added good. Therefore it is very important to study Korean images and develop products with Korean identity to improve the ountry's competitiveness in this age of limitless global competition. In this sense, colors are a very important factor that provides manufacturers with high added value, and consumers with pleasure and continuous interest in products. In short, colors are a factor, more than function, which directly determines consumers' choice of products. Japan whose standardization of traditional colors is much developed compared to Korea, continues to introduce their unique cultural images to the world by analyzing preferred colors of the nation and applying them to production. Therefore it is clear that the use of traditional colors reveals the essence of a nation's tradition and recreates its characteristics. And it plays a great role in changing their own cultural goods into global ones. The purpose of this thesis is to study how to express things which are most Korean as most Korean using the package designs of Hangwa, a traditional Korean snack, by the right interpretation and well-defined composition of traditional Korean colors.
