This study examines the role of six species of microalgae, including Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO), on hair loss prevention and scalp improvement. To determine the effects of microalgae extracts on hair loss prevention and scalp improvement, antioxidant activity, cell proliferation in HaCaT cells and HFDPC cells, and the inhibition level of 5-alpha reductase activity were examined. In the study of antioxidant activity, the $EC_{50}$ values of DPPH anti-radical activities indicated that the SO, CG, and ST9 treatment groups demonstrate significant antioxidant activity. In the study of the hydroxyl radical scavenging activity, CG (6.6~42.1%), ST9 (26.0~44.0%), and SO (7.8~44.3%) demonstrated significant effects. Furthermore, SO promoted the proliferation of HaCaT cells and a human epidermal cell line during a 6-day treatment. In the study of the proliferation of HFDPC cells, a hair follicle dermal papilla cell line, CG, and SO significantly stimulated cell proliferation. Finally, PT, CG, and SO significantly inhibited 5-alpha reductase activity. These results suggest that among the six microalgae used in this study, CG and SO have antioxidant effects, induce cell proliferation, inhibit 5-alpha reductase activity, and can be used for hair loss prevention and scalp improvement.

As considering a comparison study of the structure of mind and psychologic type of C.G Jung to Ji-In-Lon and Sa-Sang constituition of Lee Je Ma, I've got the following conclusion. 1. The study of the structure of mind of Jung and Ji-In-Lon of Lee Je ma have a important meaning to each theory of type of men. They developed their own peculiar theory of type men by the analysis of the mind of men. 2. Jung explained the organization of recognition by four phase theorical structure; consciousness, personal unconsciousness, collective unconsciousness, self. Lee Je Ma explained the organization of recognition by four phase theorical structure;Sa, Sim, Sin, Mul. And theory of type of men, Jung established four type; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Um-In, They all established the four phase structure, which have things in common. 3. Jung studied the consciousness and unconsciousness and Lee Je Ma studied the Sung-In, Eui, Ye, Ji, and Sim-Yock-Bi, Bak, Tam, Na. I think they have a close relationship. And I think there is relationship between consciousness, unconsciousness to Gun-Ja-Ji-Sim, So-In-Ji-Sim. 4. I think there is thought of relationship between Lee Je Ma's Dae-Dong, Gak-lip, Hang-gi-ji, Hang-gi-hang and Ho-sun, Oh-ak, Sa-sim, Tae-hang and relationship of internal organ's size to Jung's the first function, second function, third function, fourth function. 5. I think the relationship between the type of Jung;thinking type, feeling, type, sensation type, intuition type to the type of Lee Je Ma; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Yang-In, So-Um-In needs more study.

It was investigated to develop the technology for simultaneous removal of $SO_2/NO$ in flue gas using liquid homogeneous catalyst. Test was carried out using a bench scale and a pilot scale experiment. The investigation led to the following results: 1) Removal efficiency of $SO_2$ gas showed good results regardless of operating condition. Removal efficiency of NO gas, however, proportionally increased with higher packing height, lower concentration and larger injection rate of catalyst 2) The optimum design parameters for simultaneous removal of $SO_2/NO$ gas using Fe(II)-EDTA catalyst were as follow: HTU(height of transfer unit) = 0.5 m, liquid gas ratio = 20 $L/m^3$, NTU (number of transfer unit) = 3 stages, cross dimension of scrubber=0.025 $m^2$ 3) The removal efficiencies of $SO_2$ and NO were 95% and 81%, repletely. 4) The high HTU is advantageous on removal of the NO, but the excessive HTU diminishes operating efficiency. Consequently, it is important to decide the HTU of optimum.

In this paper, we present the design of a system on a chip(SoC) based on Powerline Communication for Power-IT. The SoC deals with power information obtained from analog to digital converter and transmits this data via powerline. We integrate main processor, ADC and PLC function into a chip. Also a FPGA-based emulation system is introduced to evaluate a proposed SoC architecture.

Sulfonated poly(ethylene glycol) (PEG-$SO_{3}$) grafted polyrotaxanes (PRx-PEG-$SO_{3}$) were prepared in order to utilize the unique properties of PEG-$SO_{3}$ and the supramolecular structure of PRx, in which PEG-$SO_{3}$ grafted $\alpha$-cyclodextrins ($\alpha$-CDs) were threaded onto PEG segments in a PEG-b-poly(propylene glycol) (PPG)-b-PEG triblock copolymer (Pluronic) chain capped with bulky end groups. Some of the PRx-PEG-$SO_{3}$ demonstrated a higher anticoagulant activity in case of PRx-PEG-$SO_{3}$ (P 105), and compared with the control they showed a lower fibrinogen adsorption in PRx-PEG-$SO_{3}$ (F68) and a higher binding affinity with fibroblast growth factor. The obtained results suggested that polyrotaxane incorporated with PEG-$SO_{3}$ may be applicable to the surface modification of clinically used polymers, especially for blood/cell compatible medical devices.

$SO_2$ has been absorbed and separated selectively by an ionic liquid from $SO_2/O_2$ mixture decomposed from sulfuric acid during the thermochemical SI cycle for the water splitting. In order to design and operate high pressure $SO_2/O_2$ separation system, the solubility of $SO_2$ in [EMIm]$EtSO_4$ (1-ethyl-3-methylimidazolium ethylsulfate) has been measured by Magnetic Suspension Balance at high pressure and temperature. Based on the measured solubility, a pressurized separation system was set up and operated. 194 L/h of $SO_2$($SO_2:O_2$=0.65:1) has been separated with 99.85% of $O_2$ at the vent of absorption tower, which is 22.7% of the theoretically ideal capacity of the system. This discrepancy results from the reduced contact between the gaseous $SO_2$ and the ionic liquid. Increased $SO_2$ supply, scale-up of the absorption column, and a faster ionic liquid circulation speed were suggested to improve the separation capacity.

ZhangSanRoei's "NanKyungHeoJuJenJung" is a book which is composed of 'HeoJu'(collection of traditional explanations) and 'JenJung'(his own ideas). In this research, I considerd of "NanKyungHeoJuJenJung"'s theory of 'meridian' mainly by the original text. ZhangSanRoei said that it is right in the traditional theory that the 12 channel is always arranged 'pulse', and 'kikyung 8 channel' is subsidiary, so both of them are important. But, he was influenced by western medicine, he criticized that 12 channels' lenth is 16zhang2chuk, and are stared in 'Sutaeyinpaekyung' and left kidney right myungmun theory.

Objective : The studies on liver effect in administration of western medicine have been well-established so far, but the studies on liver effect in administration or herbal medicine haven't been made. To make things worse, people who have liver disease generally believe that taking a herbal medicine is not useful to take care or their disease and even think it can cause liver disease. But this belief is not verified at all. And some doctor claim that herbal medicine is good to cure liver disease. So those various assertion makes patients to feel confuse about taking a herbal medicine. so we feel the need to study about how taking herb medicine affect to liver disease patient. Methods : First we chose the 12 patient who seems to have the liver disease on the index of biochemistry test and we administrate the herbal medicine and after several day or weeks we recheck the biochemistry test. Results : Through the this method, we find the positive effect of taking herbal medicine on the patients who have the liver disease. Conclusions : Our results give no evidence that herbal medicine is harmful for liver disease. We need to study more about this.

Human immunodeficiency virus type 1 (HIV-1) integrase plays a critical role in the life cycle of the HIV virus. An ability to accurately map its electrostatic potential, and then use this information to predict the manner in which DNA will bind to the active site of the catalytic domain could provide a foundation for inhibitory design. Attempts to discern the crystal structure of HIV-1 integrase have proven problematic, especially in the region of enzymatic activity, that being those residues involved in the catalysis of the integration of viral DNA into the host cell. However, there is a structural correlation in to the region of interest with avian sarcoma virus (ASV), so a homology model utilizing this similarity was constructed to approximate the behavior/structure of the undetermined portions of the HIV-1 integrase crystal. After this model was constructed and its energy minimized, electrostatic calculations were carried out on the substance, so that an electrostatic potential map was constructed. Using this information, it was determined that DNA binding was oriented so as to exploit the regions of positive potential nearby the active site, as well as the positive potential of the magnesium cofactors.

Medium optimization for xylitol production from xylose by Candida parapsilosis ATCC 22019 mutant was performed. Effect of various nitrogen sources on xylitol production was investigatied. Of inorganic nitrogenous compounds, ammonium sulfate was effective for xylitol production and yeast extract was the most suitable orangic nitrogen nutrient for enhancement of xylitol production. Effect of inorganic salts such as KH$_{2}$PO$_{4}$ and MgSO$_{4}$-7H$_{2}$0 on xylitol production was also studied. Optimal medium was selected as xylose of 50 g/l, yeast extract of 5 g/l, (NH4$_{4}$)$_{2}$SO$_{4}$ of 5 g/l, KH$_{2}$PO$_{4}$ of 5 g/l, MgSO$_{4}$-7H$_{2}$O of 0.2 g/l. In a fermentor by using the optimal medium, a final xylitol concentration of 37 g/l could be obtained from 50 g/l of xylose with a xylitol yield of 74% and a xylitol productivity of 0.58 g/1-hr. At 300 g/l xylose, fermentation was also carried out and then a final xylitol concentration of 242 g/l was obtained at 272 hours. It was corresponding to xylitol yield of 80.7% and xylitol productivity of 0.58 g/1-hr.
