In this study, the elevational distribution of breeding birds in Seoraksan National Park, Korea was investigated. Forty-six species of birds were documented from line transect surveys taken from Seorakdong at 230 m above sea level (a.s.l.) to the Daechungbong summit at 1708 m asl. Birdspecies richness and diversity were highest in Seorakdong and lowest at the Daechungbong summit. As elevation increased, bird species richness and diversity decreased, with a humped-shape trend being observed between 700 m and 1200 m a.s.l. Stepwise analyses revealed that breeding bird species diversity indices were significantly negatively correlated with elevation (r² = 0.327, P < 0.001) and positively correlated with vegetational coverage (r² = 0.324, P = 0.046). Higher elevations supported fewer birds than low and intermediate elevations. Projections at the local scale, including data on behavior and habitat use by birds, will be necessary for optimal conservation and management of the bird communities in Seoraksan National Park.

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.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

RF-MW 혼합프로세스를 사용하여 다이아몬드 막을 만들 때, 우선 RF 플라즈마CVD법으로 실리콘 기판 위에 다이아몬드 시드를 증착시키고, 그 시드로부터 MW 플라즈마CVD법에 의해 다이아몬드 막을 성장시켰다. RF-MW 혼합프로세스를 사용하여 성장된 다이아몬드 막은 MW 프로세스만으로 성장된 막에 비해 결정입계의 크기는 작고, 조밀해졌으며, 결정성 또한 더 좋아졌다. 성장된 다이아몬드 막은 전자현미경, X-선 회절기, Raman분광기 등으로 분석하였다. In case of making the diamond films by using RF-MW mix-process, at first. diamond seeds were deposited on silicon substrate by RF plasma CVD, and then diamond layer grown by MW plasma CVD from the seeds. The grain-size of diamond films deposited by using RF-MW mix-process was smaller and denser, in addition, crystallity of diamond films was better than MW plasma CVD process. The deposited diamond films were analyzed by SEM, XRD, and Raman spectroscopy.

The purpose of this study was to evaluate the therapeutic effect of praziquantel (Embay8440, Biltricide®) on human cerebral cysticercosis. The praziquantel is a broad spectrum anthelmintic agent and has a high activity against cestodes and trematodes. Before and after the treatment with oral administration of the praziquantel the changes in structure of Cysticercus cellulosae biopsied in subcutaneous tissue were studied by scanning and transmission electron microscope, and cerebral cysticercosis by computerized tomographic scanning. The results were as follows : 1. The findings of the observations on subcutaneous Cysticercus biopsied after treatment were compared with those of before treatment. At the early stage of the treatment, small vacuoles were scattered along the basement layer in the tegumental syncytium of the scolex and neck regions. In the scanning electron microscopic observation, marked surface changes were present in the neck region with many bleb-like structures formed by the bursting of the large vacuoles in the tegumental syncytium. In the specimens biopsied at 2 or 5 weeks after treatment, the degenerations and necrosis of the tegumental syncytium were seen in all part of cysticercus. 2. The scanning electron microscopic findings of Cysticercus cellulosae obtained from the 4th ventricle of the cerebral cysticercosis patients by the surgical operation were identical with those of subcutaneous tissues. 3. In 12 cases of cerebral cysticercosis treated with prziquantel in dosage of 3×25 ㎎/㎏ for 3 or 4 consecutive days, there were no cessations of the convulsive seizures during the 6 months follow up. Among them 9 cases were given again with the same doses of the drug for 4 or 7 days. In 7 of 9 cases, no more convulsive seizure was experienced over one or two years after the second treatment. At the same time the lesions of the brain C.T. scanning were disappeared, decreased in size or calcified. In the other 3 cerebral cysticercosis cases, the complete cure was also obtained after the oral medication of praziquantel with the doses of 3×25 ㎎/㎏ for 7 consecutive days. 4. In the treatment of cerebral cysticercosis with praziquantel, it was found that the combined oral medication of dexamethasone during the course of treatment was effective on preventing and minimizing the side effects.

School has a responsibility on its students for making their ideal sense of values and guiding them correctly to physical, mental and social health. If we consider this fact, we'll understand the reason why the physical education in middle school has a awful lot meaning to the students. So the purpose of this study is to investigate the influence that an Intramural Sports Involvement of a Middle School has on social implications development. The subject of this study were 330 non-athletes Middle School students in Daejeon Metropolitan City selected by the stratified cluster random sampling. And I studied 317 students among them finally. For the method of collecting the data, I chose the questionnaire written by Jung, Bum-Mo(1971) and standardized by the study of Han, Tae-Ryong. And the numerical value of this data was Cronbach' a=.62 For analyzing the data, I used the technical statistics and the one-way ANOVA. So the conclusion of the influences that an Intramural Sports Involvement of a Middle School has on social implications development. 1. The development of socialization according to the vital statistical has similar differences among groups. About the difference of the development of socialization according to the gender, male students are superior to female students in direction and self control and female students are superior to male students in stability and social contact. About the difference of the development of socialization according to the grade, lower graders are superior to higher graders. 2. The development of socialization according to an Intramural Sports participation has similar differences among groups. About the difference of the development of socialization according to the time of the participation, the activity and the direction are proportional to the time or the participation. And about the difference of the development of socialization according to the period of the participation, the activity and the self control are proportional to the period of the participation.

The visible light-curing posterior composite materials are used extensively due to their esthetic characteristics. Many disadvantages of marginal leakage, wear and poor strength should be overcome through improvement of mechanical properties. It has been proved that most of materials could be improved by additional heat curing after light curing. The objectives of this study was to estimate the effects of additional heat curing on the five different commercial posterior light curing resins, P-50, Herculite XR, Heliomolar, Prisma AP. H, Clearfil Photoposterior. Additional heat(CRC system, Kuraray Co., Japan) of 100℃ was applied for 0, 5, 15 and 25 minutes after light curing with Visilux Ⅱ (3M Co., U.S.A.). The diametral tensile strength was measured by using UTM (Instron 6022, U.S.A.) of cross head speed of 1cm/min after storing in 37℃, 100% humidity for 10minutes and 24 hours. The following conclusions may be drawn from this study. 1) When heat was applied on tested specimens, diametral tensile strength was increased in proportion to period of heat applying in early stage. However, there were differences of diametral tensile strength in each tested materials. 2) The highest diametral tensile strength was shown after 5 and 15 minutes of heat application. 3) When it was compared between 24 hours and 10 minutes group, former showed higher values. Heat application after light curing on VLC posterior composite resins showed increase of diametral tensile strength on this study. Not only the temperature applied but period of heat application seemed affect the strength of this materials. The further investigation of proper temperature and period of heat application for each materials was recommended.

In order to observe the epidemiological changes of clonorchiasis in the high endemic area in Korea, the stool examinations were carried out in Bulam-dong, Kimhae City. A total of 423 stool specimens collected from the inhabitants of this area were examined both by cellophane thick smear method and Stoll’s egg dilution counting technique. The result of this survey was compared to the data obtained in 1973 by the quantitative analysis applying the regression equations, the simple and two-stage catalytic curves. The metacercarial density of Pseudorasbora parva and the tendency of familial aggregation of this area were also compared with those of 1973. In addition to this study informal interview were conducted to investigate the KAP (knowledge, attitude and practice) of the raw fish eating habit of the ingabitants in this area. The results are as follows: 1. Overall prevalence rate of clonorchiasis was reduced from 68.3% to 45.6% in a period of 10 years. 2. In 1973, both sexes in all age groups showed almost parallel high infection rates. However in 1983, the rate for males was slightly higher than that for females and a marked reduction in the prevalence was encountered in the youngest age group. 3. The mean E.P.G. count of Clonorchis sinensis infection in the surveyed area was 10,846 in 1973. But the mean E.P.G. count was decreased to 4,858 in 1983. The degree of intensity of Clonorchis sinensis infection determined by E.P.G. count was evenly distributed in geavy, very heavy, light and moderate infections in 1973 whereas an E.P.G. of over 10,000 was seen only in 14.0% of examinee in 1973. 4. The two-stage catalytic model was applied to this study and the calculation led to the equation y=1.042(e^(-0.003t)-e^(-0.074t)); a>b in 1973, and y-1.130(e^(-0.003t)-e^(-0.026t); a>b in 1983. 5. The intensity of endemicity was compared with the regression equations calculated from cumulative percentages of E.P.G. counts. The regression equations were y=2.75+1.46 log^(χ)(Cs. D_(50) 64.76) in 1973 compared to y=3.27+1.59 log^(χ)(Cs. D_(50) 12.25) in 1983. 6. In high endemic area such as Kimhae City the tendency of familial aggregation was recognized not in 1973 but in the present study. 7. Metacercarial infestation rate of P.parva did not change but metacercarial density was decreased from 1,312.4 ea/fish to 1,233.4 ea/fish in 1972 and 1973 to 160.8 ea/fish in 1983. 8. The KAP(knowledge, attitude and practice) of raw-fish eating habit of inhabitants were mentioned.
