Anomalous Beam Splitting Phenomena Based On Negative Refraction in Photonic Crystals

Chung, Kyo-Bang,Kim, Ahyoung Research Institute of Science and Technology HONGI 2005 Hongik Journal of Science and Technology Vol.9 No.-

We report an anomalous Y-branching phenomenon for normal incidence of light, in a 2D photonic crystal composed of dielectric rods arranged on a square lattice in air. From the calculation of the band structure and the corresponding equi-frequency contour, we examine the origin of this anomalous beam splitting. By performing the finite-difference time-domain simulation, we present the time evolution of the electromagnetic wave for the Y-branching phenomenon.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

The purposes of this study were, first, to analyze the present conditions of special education financing, second, to develop a model for estimation of the standard educational expenditures per student for special education, and third, to seek a stable revenue plan by which special education programs are supported properly. To achieve these purposes the study (1) reviewed and analyzed the pertinent literature and documents regarding special education finances, and (2) interviewed personnel who work closely in special education. Major results of this study are summarized as follows: 1) Compared with normal children, handicapped children require 2.3 time to 10 time the educational expenses per student depending on the degrees and kinds of handicaps because of additional services, small size of classes, double services of special education for handicapped children, broading systems, employments and recreational services. 2) The educational finance in Korea are 17.7% of GNP, 20.1% of the government budgets. The proportion of public education expenditure to GNP is 3.7%. This proportion is a little low compared with the international average rate 5.7%. Local government supports only 26.3% of educational finances and the national government, 73.7%. Most of the local educational expenditures are dependent on the national government. Public education expenditures per student are $1,263 in special schools, $356 in elementary schools, $3.26 in junior highschools, $431 in senior high schools. 3) There is no standard to estimate education expenditures on a per-student basis in special education in Korea. At present, the allocations of funds are made on the unit of school or class without considering the individual needs of education. Therefore a new model was developed in order to set up the standard for estimation of educational expenditures per student in special schools. A new special school which has 12 classes (elementary 6, junior high 3, senior high 3) was proposed based on the new model. It amounts to 1,367,000,000 won for a school of visually handicapped, 1,328,000,000 won for a school of hearing impaired, 1,294,000,000 won for a school of mentally retarded, and 1,322,000,000 won for a school of physically handicapped. The average of educational expenditures per student in special schools amounts to 2,389,842 won, which is almost twice that of educational expenditures provided, i.e. 1,124,702 won until now. On the other hand, as a result of calculating desirable educational expenditures in relation to the Special Educational Promotion Plan ('85-'91) which and been suggested by the Ministry of Education, Korea, a total budget of 127,100,000,000 won is needed during the seven-year plan, considering the annual increase of 18,100,000,000 won on the average. 4) The stable revenue plan of special education finance are presented: ① The government should improce and supplement current educational financial system and enact relating laws to secure special education finance. ② Local government should establish a system that a certain proportion of local tax revenues should be used for the local educational expenditure and a part of it for special education. ③ For revenue plan of special education finances should be distributed according to necessity and improvement of current method of distribution. ④ Donations from enterprises, religious organization, benefactors, parents of student can be provided to meet deficits of special education finance. The following recommendations were drawn from the basis of this study: 1) The responsibility of national and local government in the securing of the special education financial resources should be increased. 2) Measures should be taken for the equal distribution of education finance in accordance with the educational necessity. 3) Financial assistance for the private special school should be strengthened in terms of obligatory education. 4) Administration, finance, and orgainzation of special education should be strengthened. 5) Decisive steps should be taken in finance system improvement in relation to finance revenue plans suggested in this study, and changed in policy. 6) Futher studies on the analysis of investment, distribution, administration and security of education finance should be conducted continuously under the quidance of the government.

A healthy 35-year-old man who was scheduled for closed reduction of nasal bone fracture developed atrial fibrillation during induction of general anesthesia after intravenous glycopyrrolate injection. During emergence of general anesthesia, atrial fibrillation was suddenly changed to paroxysmal supraventricular tachycardia with 200 beat per minute and lasted for about 10 seconds. Because blood pressure was stable, esmolol was used to reduce ventricular response. At recovery room, ventricular response reduction about 55 beat per minute was observed after intravenous injection of verapamil 5 mg. Thereafter, the rhythm was returned to normal sinus rhythm with bradycardia.
