  • The concern of the antioxidant micronutrient status in normal healthy people, including antioxidant trace minerals such as Cu, Zn, Mn, Fe and Se is focused since systemic oxidation is involved in various chronic diseases. In the present study, we evaluated the concentration of trace minerals (Cu, Zn, Mn, and Fe) which are considered as potential antioxidant minerals in plasma, red blood cells (RBCs) and urine in normal healthy Korean subjects. The 760 subjects (male 341, female 419; mean age 54.2 $\pm$ 18.9) were recruited from the rural, urban and metropolitan city in South Korea. Dietary intake was evaluated using 24-hours recall for general major nutrient intake assessment. The trace elements (Cu, Zn, Mn, and Fe) concentrations in plasma, RBCs, and urine were measured by inductively coupled plasma spectrophotometer (ICP) and atomic absorption spectrophotometer (AAS). Cu and Zn levels in plasma, RBCs and urine in normal healthy South Koreans were within the normal range of those mineral levels, but Mn and Fe levels were higher compared to the normal range of those mineral levels. None of the selected trace mineral levels in plasma and RBC's was lower than the normal range value. The results showed that Zn and Cu levels in plasma and RBC's in Korean were within the normal range, and plasma and urinary Mn and Fe levels were higher than the normal reference values. Potential antioxidant trace mineral (Cu, Mn, Zn and Fe) levels in Koreans are within or a bit higher than the normal range.

  • The research follows several steps. First, the chinese 'WangSung' and 'KungSi' System are verified positively. Next, the structure of palace in Choson Dynasty is deduced based on those chinese systems. Finally, the common system that is also applied in other government-operated spaces is found. The result can be summarized as follows. It is clarified from reviewing the chinese 'WangSung' and 'KungSil' Systems that the 'OyoiCho' is located in 'WhangSung(the imperial city) but out of' KungSung(the palace). Therefore, the research points out that all sort of theories explaining the 'OyoiCho' of Choson Dynasty is a space of 'in-place' are false. The palace system of Choson dynasty seeks the substantiality grounded on the substantial function of 'SamCho(three spaces)' rather than its strict principle dividing main spaces by several doors-'KungMoon' Moreover, it is also certified that the 'ChonChoHooChim' system, literally the political court is located at the front and the private section is at the other(back) side, is directly applied on the palace of Choson Dynasty. This idea has been developed into 'inner and outer' concept and repressed in palace as the 'OyoiChon(outer palace) and NaeChon(inner palace)' concept. conclusion, the research suggests that the dual concept in space such as 'ChonHoo(front and back) and 'NaeOyoi(inner and outer)' basically comes from 'Eum Yang' theory and influences in building other government-operated spaces: for example 'ChongMyo(the royal ancestors shrine)', 'SoWon(a private school of Choson dynasty), 'HyangKyo(a local school annexed to the Confucian shrine)' and 'KwanAh(a governmet agency)'

  • Maek Kyoung(Mai Jing, 脈經) is the first chinese specialized book of diagnostics written by Wang Hee(Wang xi, 王熙) from Seo Jin(xi jin, 西晉). He assorted the contents with pulse and medical examination from Nae Kyoung(nei jing, 內經), Nan Kyoung(nan jing, 難經), Sang Han Ron(shang han lun, 傷寒論) and Jung Jang Kyoung(zhong cang jing, 中藏經). And united with his own research, he explains medical examination and the way of talking the pulse by classifying into entrance and class. Maek Kyoung(Mai Jing, 脈經) was imported Korea by Ji Chong(zhi cong, 知聰) AD 561, and he passed through Ko Ku Ryeo(gao gou li, 高句麗) with Nae Wei Jeon(nei wai dian, 內外典), Yak Seo(yao shu, 藥書), Myung Dang Do(ming tang tu, 明堂圖) and MaekKyoung(Mai Jing, 脈經) to be naturalized in Japan. This treatise make a special study of the second volume of the Maek Kyoung. It consists of the four chapters : Pyoung Sam Kwan Eum Yang E Sip Sa Ki Maek Je I1(平三關陰陽二十四氣脈第一), Pyoung In Young Sin Mun Ki Ku Jeon Hu Maek Je E(平人迎神門氣口前後脈第二), Pyoung Sam Kwan Byoung Hu Byoung Chi Eui Je Sam(平三關病侯幷治宜第三), and Pyoung Gi Kyoung Pal Maek Byoung Je Sa(平奇經八脈病第四). Bi Geup Choun Geum Yo Bang(備急千金要方) and Eui Hak Ip Mun(醫學入門) quoted from the contents in the second volume of Maek Kyoung, and Bin Ho Maek Hak(瀕湖脈學), Gi Kyoung Pal Maek Go(奇經八脈攷) and Maek Eo(脈語) extracted from contents in the second volume of the Maek Kyoung and requoted from this contents. Contents in the second volume of the Maek Kyoung have very valuable data like that, but the literature on this subject in the form of a treatise has not been yet in Korea. So I hope this study will be useful to develope Diagnostics by correcting translation and interpretation and fixing wrong translation.

  • A new trichostome ciliate, Balantidium honghuensis n. sp., was isolated from the recta of Rana nigromaculata and R. limnocharis during parasite surveys in Honghu Lake, Hubei Province, central China in summmer of 2010 and 2011. Its detailed morphometric characters based on LM and SEM studies were described herein. The organism is oval in shape and thickly ciliated. The vestibulum is "V" shaped and occupies about 1/3 to 2/5 of the body length. The vestibular and nearby regions possess strong peripheral fibers which form a marked axial fiber about the cytopharynx. More than 10 contractile vacuoles are distributed along the periphery of the latter body. Comparisions were made between this new species and B. sinensis Nie, 1935. They were discriminated from each other in terms of general body forms, body size, and vestibulum shapes. Besides, special attention was paid to its high-speed daughter swarmers which we believed to be the infective stage of B. honghuensis. Possible infection routes of anura amphibian balantidia were discussed.

  • This study presents a power distribution control scheme for a three-phase interleaved parallel DC/DC converter in a battery energy storage system. To extend battery life and increase the power equalization rate, a control method based on the nth order of the state of charge (SoC) is proposed for the charging and discharging processes. In the discharging process, the battery sets with high SoC deliver more power, whereas those with low SoC deliver less power. Therefore, the SoC between each battery set gradually decreases. However, in the two-stage charging process, the battery sets with high SoC absorb less power, and thus, a power correction algorithm is proposed to prevent the power of each particular battery set from exceeding its rated power. In the simulation performed with MATLAB/Simulink, results show that the proposed scheme can rapidly and effectively control the power distribution of the battery sets in the charging and discharging processes.

  • The recent power systems are very complex and to model them completely is impractical for analysis of electromagnetic transient. Therefore areas outside the immediate area of interest must be represented by some form of Frequency Dependent Network Equivalent (FDNE). In this paper a method for developing Frequency Dependent Network Equivalent (FDNE) using Z-domain rational Function Fitting is presented and demonstrated. The FDNE is generated by Linearized Least Squares Fitting(LSF) of the frequency response of a Z-domain formulation. This Three-port FDNE have been applied to the test AC power system. The electromagnetic transient package PSCAD/EMTDC is used to assess the transient response of the Three-port FDNE developed under different condition. The study results have indicated the robustness and accuracy of Three-port FDNE for analisys of electromagnetic transient and harmonic assessment.

  • In this paper, we approach the problem of image filter design automation using a kind of intrinsic evolvable hardware architecture. For the purpose of implementing the intrinsic evolution process in a common FPGA chip and evolving a complicated digital circuit system-image filter, the design automation system employs the reconfigurable circuit architecture as the reconfigurable component of the EHW. The reconfigurable circuit architecture is inspired by the Cartesian Genetic Programming and the functional level evolution. To increase the speed of the hardware evolution, the whole evolvable hardware system which consists of evolution algorithm unit, fitness value calculation unit and reconfigurable unit are implemented by a commercial FPGA chip. The Celoxica RC1000 card which is fitted with a Xilinx Virtex xcv2000E FPGA chip is employed as the experiment platform. As the result, we conclude the terms of the synthesis report of the image filter design automation system and hardware evolution speed in the Celoxica RC1000 card. The evolved image filter is also compared with the conventional image filter form the point of filtered image quality.

  • The present study investigated the antitumor activity of the aqueous-alcoholic extracts from unripe cotton balls of Gossypium indicum. An Exposure of murine B16 melanoma and L1210 lymphoma cells to the extracts resulted in their severe deaths in time- and concentration-dependent manners. Of the extracts, hydrophilic fractions were most efficacious for the antitumor activity and found to contain certain amounts of catechin and its derivatives. The hydrophilic extract fraction C36B2-8 had approximately 10 times more cytotoxic effects on B12 and L1210 cells than on isolated murine thymocytes. High concentrations (>150 $\mu$g/ml) of C 36B3-8 mainly induced necrotic cell death. At low concentrations (<100 $\mu$g/ml), however, C 36B3-8 induced not only necrosis but also apoptosis of the two tumor cell lines, which was proved by the TUNEL staining and DNA fragmentation techniques. The data indicate that certain ingredients of the cotton ball extract of G. indicum have an antitumor activity.
