The direct reaction method has been used for the fabrication of Al-Mg/Al₂O₃functionally gradient materials. It was found that the reaction layer of the Al-Mg/Al₂O₃powder compact at 900℃ under air atmosphere led to the formation of reaction layers with varying ceramic phase contents. As the results of experiments by using the TGA system, the characteristics and growth behavior of the reaction layers were affected by the reaction temperature, the gas flow rate, the Mg contents and the Al₂O₃contents.

Development of Molecular Markers for Bentazone-Resistant Wheat (Triticum aestivum L.) Induced by Gamma-ray Irradiation

김재윤,서용원,장철성,D. S. Kim,김대연,J. B. Kim,K-R Kim 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.I

Wheat mutants generated from a cultivar ``Geumgangmil"by using a $^{60}$Co source (gamma-ray) were developed for bentazone (3-isopropyl-2,1,3-benzo-thiadiazin-4-one-2,2-dioxide) resistance. Resistant M$_2$ plants were selected from seedlings and adult plants consecutively. Bentazone-resistant wheat plants were able to survive at up to 10 times (1,600 ppm) the commercially recommended concentration. The four plants with the highest bentazone resistance were selected. An AFLP (amplified fragment length polymorphism) analysis was applied to identify molecular markers for bentazone-resistant wheat mutants. Twelve polymorphic products, which were unique to bentazone-resistant plants, were identified, cloned, and sequenced. Among the twelve polymorphic bands, eight Sequence-tagged Sites (STS) primer sets were designed. Only one STS primer set (HRMW-08) was converted a ``Bentazone-resistant wheat-specific" STS marker. The wheat mutants and markers that we obtained could be employed in a cross-breeding program incorporated with marker assisted selection (MAS) in the early stages of population segregation.

The purpose of this study was to observe the effects of Far-infrared on mice rheumatoid arthritis induced by type II collagen. The author peformed several experimental tests which were the hematoxylin-eosin tissue stain, the hind paw thickness, and ELSIA of cytokines(TNF-$\alpha$, IL-1$\beta$). On day 14 and 21, FIR-Tx. group decreased in synovial membrane thickness more than control II group FIR-Tx group decreased in hind paw thickness more than control II group. In the ELISA test of TNF-$\alpha$ concentration, control II group significantly increased in the concentration more than normal and FIR-Tx. group on day 7, 14, and 21. In the ELISA test of IL-$\beta$ concentration, FIR-Tx. group decreased in the concentration more than control II group on day 14 and 21. With J's Linear Function Data Process Program, researchers can get the estimated the concentration or the hind paw thickness from this experiment. The estimated results would be a good guide to therapists and researchers, planning Far-infrared application on the rheumatoid arthritis. These results indicated that far-infrared irradiating appeared to reduce the concentration of TNF-$\alpha$ and IL-1$\beta$ at mouse model of autoimmune arthritis. It would be considered that Far-infrared has an effect on relieving rheumatoid arthritis.

껍데기뿐인 '도서관 및 독서진흥법' 어떻게 살릴까

이미 4년전 제정된 '도서관 및 독서진흥법'은 실질적으로 시행되지 않은 채 사문하 돼 있다. 기금이 조성되지 않으니 예산이 없고 예산이 없으니 활동이 없다. 이 법에 명시된 대로 정부는 국고에서 기금을 출현해야 하며 효율적인 운영이 이뤄지도록 실효성 있는 법체계로 개정해야 한다.

N/A The present study was conducted to estimate the fatigue crack growth rate of the Mo-Ni alloyed ductile cast iron for the influence of austempering temperature and time. The fatigue crack growth rate was affected by retained austenite. Retained austenite volume were higher with the ductile cast irons which were austempered at 360℃ than austempered at 260℃, and the fatigue crack growth rate of the former was lower than that of the latter. Also, the fatigue growth rate of the former was the lowest at austempering for 1hour and that of the latter was the lowest at austempering for 3hours.

Far-Infrared의 발전사와 물리치료 적용에 대한 연구

The Sun's ray is composed of Infared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(60%). IR(20%), and UV(20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time, in the Industrial Revolution the Infrared and FI R had been begun to use making products. In asia. also, asian already has made use of FIR to treat the body, product things and make warm the house in the winter, as it had been called Wull therapy, fermentation. and On-Dol system. In these days, with contemporary science FIR would be begun to clear up the implication in the human body and organic compounds. IR classified by wavelength three parts NIR, MIR, FIR. There is FIR which is radiated from healthy human body the wave length is 8-14 m. It is difficult to standardized the wavelength of IR, since each related associations have a different opinion, so we suggested ideal IR wavelength and biological, phsiotherapical, medical FIR wavelength.

Hershel found out Infrared for the first time, in the Industrial Revolution the Infrared and FlR had been begun to use making products. FIR with low temperature can deeply penetrate on the human body composed things without troublesome. since FIR has effectively operated on the human body at low temperature (35-40$^{\circ}$C). When FIR penetrated on the human body, it would inhibit the abnormal genes and cells expression, and then information of DNA and RNA would be reexpressed for arranging DNA and RNA abnormal state. As FIR's receptors in the body, it colud be presumed that N-glycosyl linkage of purine and deoxyribose, RNA splicing process. and Heat shock protein. To radiate optimized FIR, in this study, we made the FIR radiation compound and instrument for unharming biological things. According to the results, the FIR radiation to E. coli., it did not induce genetic mutations and change the survival rate of E.coli.

김재윤,Chang Hyu Lee,Youn Kyoung Won,Bum Sik Chin,Hyung Sik Shin,Jae Yoon Kim 대한감염학회 2014 Infection and Chemotherapy Vol.46 No.1

Background: Rabies is an acute fatal viral disease generally transmitted from infected animals to humans through bites. It is distributedworldwide. The number of Korean people traveling to rabies-endemic countries and being bitten by infected animals has beenincreasing recently. Therefore, we investigated international travelers who received rabies post-exposure prophylaxis (PEP) at the NationalMedical Center (NMC) and compared the data with those of other clinics. Materials and Methods: This study was a retrospective review of 106 patients who visited the International Travel Clinic of the NMCand received rabies PEP between July 2006 and December 2012. During that period, we used the Essen intramuscular regimen protocol. Complete rabies PEP was defined as 5 doses of rabies vaccination with or without rabies immunoglobulin (RIG) administrationaccording to the World Health Organization guidelines. Results: A total 106 cases documented within the period of 6 years were selected, including 10 children younger than 15 years and96 older than 15 years. The mean age of the patients who received PEP was 33.4 years. Of the patients, 53 were male and another53 were female. Most of the exposures occurred in Southeast Asia, predominantly from dog bites (71, 66.9%). The lower extremitieswere the most frequent site of exposure (37, 34.9%). All the patients began receiving rabies vaccination for prophylaxis after exposure,and 51 received rabies vaccination with RIG. Meanwhile, 74 cases (69.8%) initiated rabies vaccination overseas, but only 10 of themreceived RIG while overseas; the remaining 32 (30.2%) initiated rabies vaccination after returning to Korea. Within 7 days, all thechildren and 74 adults received their first rabies vaccination. Six adults initiated first rabies vaccination after 1 week. Eleven of the 106patients stopped PEP before 5 doses, among whom 4 (1 child and 3 adults) discontinued vaccination after confirming that the bitinganimal remained healthy throughout 10 days of observation. None of the patients had been previously vaccinated against rabies. Conclusions: Most of the overseas travelers who visited our clinic after being bitten by suspected rabid animals received appropriaterabies PEP. However, the interval between exposure and first rabies vaccination was often delayed. Tourists who planto travel in rabies enzootic regions need to be aware that prompt initiation of PEP is important to reduce the risk for developinghuman rabies.
