The objective of this article is to induce that the conception of 'Qi-jul(氣質) and Qi-pum(氣稟)' was introduced to the Sasang(四象) Constitutional Medicine from bibliographic study on the theory of 'Qi-pum(氣稟)'. The conclusions summerized as followings. 1. In the oriental medicine, qualitative difference of 'zheng-qi(正氣)' among the individuals, the opposing power against a disease, is regarded as constitution. Having been used as 'nature(素)', 'quality(質)' and 'character(氣質)' in the oriental medical book, the word of 'Che-Jil(體質)' was used in good earnest at the end of 'Qing(情)' dynasty. 2. The nature(性) is divided into two, original nature(本然之性) and charicteristic nature(氣質之性) in the 'New confucianism(新儒學)' and the former means a principle(理), is a pure and good thing and used as a conception of universality, the latter is a principle of character and a imperfect imitation of principle(理). 3. It was repeatedly confirmed that 'Qi-jil and Qi-pum' meant the difference among the individuals by the dispute of 'Li-Qi(理氣)' caused by Lee Hwang(李滉) and Lee Yi(李耳) and by that of 'Ho-Rak(湖洛)' in the Ch'o-son(朝鮮) dynasty. 4. Han Sok-Ji, based on Meng-Zi(孟子)'s doctrine that man's inborn nature is good, criticized the theory of 'Qi-pum' which was 'Zhu-Zi(朱子)'s opinion and his opinion about the life(命) was thought to clue to the classification of the 'Sasang(四象)' invented by Lee Je-Ma as Park Se-Dang's theory that everyone has common nature but has different life(命). 5. By introducing the theory of 'Qi-pum' and the conception of life(命) which was understood as a special character by Han Sok-Ji and Park Se-Dang to Sa-sang constitutional medicine, Lee Je-Ma explained the reason why each man who was classified four constitutions, 'Taiyang'(太陽), 'Taiyin'(太陰), 'Shaoyang'(少陽), 'Shaoyin'(少陰), had the different formation of the visceral department(臟局).

In the present study, the antioxidative and inhibitory activity of Zingiber officinale Rosc. Rhizomes-derived materials (on mushroom tyrosinase) were evaluated. The bioactive co mponents of Z. officinale rhizomes were characterized by spectroscopic analysis as zingerone and dehydrozingerone, which exhibited potent antioxidant and tyrosinase inhibition activities. A series of substituted dehydrozingerones [(E)-4-phenyl-3-buten-2-ones] were prepared in admirable yields by the reaction of appropriate benzaldehydes with acetone and the products were evaluated in terms of variation in the dehydrozingerone structure. The synthetic analogues were examined for their antioxidant and antityrosinase activities to probe the most potent analogue. Compound 26 inhibited Fe$^{2+}$-induced lipid peroxidation in rat brain homogenate with an IC$_{50}$ = 6.3${\pm}$0.4 ${\mu}$M. In the 1,1-diphenyl- 2-picrylhydrazyl (DPPH) radical quencher assay, compounds 2, 7, 17, 26, 28, and 29 showed radical scavenging activity equal to or higher than those of the standard antioxidants, like ${\alpha}$-tocopherol and ascorbic acid. Compound 27 displayed superior inhibition of tyrosinase activity relative to other examined analogues. Compounds 2, 17, and 26 exhibited non-competitive inhibition against oxidation of 3,4- dihydroxyphenylalanine (L-DOPA). From the present study, it was observed that both number and position of hydroxyl groups on aromatic ring and a double bond between C-3 and C-4 played a critical role in exerting the antioxidant and antityrosinase activity.

As mentioned above, I have acquired some valuable results about medical treatments with acupuncture for "Trigeminal neuralgia" after studying oriental medical books. 1. The course of medical treatments with acupuncture was, first of all, applying general ones, and then, assisting ones based on occuring area of pain and the cause. 2. For general treatments, "Chok-yangmyong-Wi-Kyong", distributed widely on the face, was used in great numbers. The order, according to the number of using times, of spots for acupuncture was Ha-kwan(11 times), Hap-kok(10), Chan-juk(7), Hyop-geo, Tae-yang, Sa-baek(individually 6). 3. For assisting treaments based on occuring area of the pain, spots of the Kyong-rak, passing through occuring area of the pain, and Kyong-woe-ki-hyol were used in great numbers. 4. The order was O-je, Chan-juk, Yang-baek(individually 8), Tae-yang(5) for the pain of first branch of the trigeminal nerve; Sa-baek(12), Kwan-ryo(6), Go-ryo(5) for the pain of second one; and Hyop-geo, Ha-kwan(individually 6), Dae-young, Hyop-seung-jang(individually 5). Seung-jang(4). 5. For assisting treatments based on the cause, "One-hyol(原穴)", "Rak-hyol(絡穴)" and "5-soohyol(五輸穴)" were used in great numbers. 6. The order was Pung-ji(10), Hap-kok(9), Woe-kwan(5) for "Woe-Kam(外感)"; Nae-jong(12), Tae-chung(10), Chok-sam-ri(7) for "Kan-Wi-Hwa-Seung(肝胃火升)"; Tae-gue(7), Sam-um-kyo, Pung-ji(individually 2) for "Ho-Hwa-Sang-Seung(虛火上升)"; Pung-ryung(4) for "Pung Dam-Jo-R ak (風痰阻絡)"; Kyok-su(2) for "Ki-Che-Hyol-Ho(氣滯血虛)".

Purpose: Job satisfaction, spouse support, parenting stress, and the factors that influence parenting stress in female fire fighters with preschool-aged children were examined. Methods: Data were collected from 180 female fire fighters who worked at the fire station from June to July 2013 and had preschool-aged children. Data were analyzed using SPSS WIN 21.0. Results: Average job satisfaction was 2.81, spouse support was 3.54, and parenting stress was 3.61. Parenting stress was negatively correlated with spouse support and job satisfaction. Job satisfaction and spouse support were positively correlated. Factors influencing parenting stress included employment period (${\beta}$=0.093, p <.05), a husband who is not a fire fighter (${\beta}$=-8.971, p <.05), having three children (${\beta}$=27.395, p <.05), delegating childcare to relatives (${\beta}$=9.605, p <.05), income (${\beta}$=-0.920, p <.05), and spouse support (${\beta}$=-0.589, p <.05). Conclusion: To reduce parenting stress and increase job satisfaction, female fire fighters with preschool-aged children should be assigned to stable administrative work instead of stressful on-site work. Husbands who are fire fighters should take advantage of paternity leave, implemented by the Ministry of Public Safety and Security, to increase their active participation in parenting.

The phylum Bacteroidetes covers phenotypically diverse groups of Gram negative rods that do not form endospores, and currently includes 6 classes, 6 orders, 33 families and 380 genera. Members of Bacteroidetes can be aerobic and anaerobic heterotrophs, hydrogen utilizing chemolithotrophs, or methylotrophs. They can be isolated from diverse habitats including terrestrial and aquatic environments, environments with extreme physicochemical conditions, and animal and plant hosts. During a series of extensive surveys of prokaryotic species diversity in Korea, bacterial strains belonging to Bacteroidetes were isolated from various sources of aquatic and terrestrial environments. A total of 22 isolates were obtained, which represent 22 unrecorded species in Korea belonging to 14 genera of 6 families. Sixteen species among them were assigned to Flavobacteriaceae, two species were to Sphingobacteriaceae, and single species was to each of the families Bacteroidaceae, Balneolaceae, Chitinophagaceae and Cytophagaceae. At genus level, Chryseobacterium (5 species) and Flavobacterium (5 species) were the most abundant genera, and single species were obtained for the genera Bacteroides, Baloneola, Terrimonas, Dyadobacter, Aquimarina, Arenibacter, Gillisia, Gilvibacter, Salinimicrobium, Winogradskyella, Pedobacter and Sphingobacterium. The detailed descriptions of each unrecorded species are provided.

In this paper, a design method of the compact narrow band filter on the microstrip board is proposed using complementary split-ring resonators(CSRRs). The design technique of this filter is based on cascading filter stages consisting of the combination of circular CSRRs, capacitive gaps between patches, and inductive grounded stubs with the meander configuration. By these means, it was possible to get the nearly symmetric frequency responses, adjustable bandwidths, compact sizes. And also excellent characteristic of the out-of-band rejection is achieved in contrast to the conventional filter design technique. The measured insertion shows good results about -4.0dB at the center frequency($f_0=1GHz$) and passband return loss is less than -9.4dB. The 3dB fractional bandwidth(FBW) is approximately 4%. The results of the frequency response measured on the fabricated band pass filter substrate show satisfactory agreement with the simulated frequency responses by the HFSS in the region of interest.

This paper proposes the design scheme of internal triple band antenna intended for using in GSM900, DCS1800, and PCS1900 bands. The suggested folding metal plates of the two branches are mounted on a dielectric coated ground plane for size miniaturization and durability. Return losses are overlapped when length of metal branches are controlled. This is important technique for wide band operation. For the suggested antenna geometry its return loss was calculated by HFSS 9 simulator, and was shown to be -10 [dB] less within the required band. Also, gain and radiation pattern of antenna were measured using far field measurement system in an anechoic chamber. The measured peak gain is more than 3.0 [dBi], and the average gain is over -1.0 [dBi] for the triple band, which is regarded as satisfactory for the internal antenna application. Also, the radiation pattern for two frequencies shows a similar shape each other within the required band.

A fertility and general reproductive a. bility study was performed in Sparque-Dawley rats intravenously injected with Ginkgo biloba extract (EGb 761), a potential pharmaceutical excipient, at dose levels of 7.5, 15, and 30 mg/kg/day. Male rats were treated with Ginkgo biloba extract (EGb 761)from 14 days before mating until 21 days after delivery. Female rats received extract for 2 months prior to mating. No abnormal signs were noted in mating or fertility of the rats treated with Ginkgo biloba extract (EGb 761). No significant external, visceral, and skeletal anomalies or mental and physical development attributable to treatment was noted in any fetuses examined. The fertility of F1 generation was not affected by the treatment also. It was concluded that Ginkgo biloba extract (EGb 761) has no harmful effect on mating, fertilization, implantation, embryonic development and normal physical development.

Porous $Al_2O_3$ hollow fiber membranes were successfully prepared by dry-wet spinning/sintering method. The SEM image shows that the $Al_2O_3$ hollow fiber membrane consists mostly of sponge pore structure. The contact angle and the breakthrough pressure were $126^{\circ}$ and 1.91 bar, respectively. This results indicate that the $Al_2O_3$ hollow fiber membranes were successfully modified to hydrophobic surface. The hydrophobic modified $Al_2O_3$ hollow fiber membranes were assembled into a membrane contactor system to separate $CO_2$ from a model gas mixture of the flue gas at elevated gas velocity. The $CO_2$ absorption flux was enhanced when the gas velocity increased from $1{\times}10^{-3}$ to $6{\times}10^{-3}$ m/s. Whereas the $CO_2$ absorption flux was decreased with the number of hollow fiber membrane of a module because of the concentration polarization. Furthermore, we developed an lab-scale $Al_2O_3$ hollow fiber membrane contactor modules and their system (i.e., $CO_2$ absorption using the $Al_2O_3$ membrane and monoethanolamine (MEA)) that could dispose of over $0.02Nm^3/h$ mixture gas (15% $CO_2$) with the removal efficiency higher than 95%. The results can be useful in a field of the membrane contactor for $CO_2$ separation, helping to design and extend a equipment.
