Since Robert Koch found tubercle bacilli in 1882, the studies on tubercle bacilli of human and animal had been carried out. Being old tuberculin(OT) introduced in 1890, the specificity of the diagnosis of tuberculosis has been improved by continual uses of heat concentrated synthetic medium(HCSM) and purified protein derivatives(PPD) tuberculin. Now, two types of tuberculin test are used worldwidly ; the single intradermal test(SIT) using bovine tuberculin and the single intradermal comparative tuberculin test(SICTT) using avian and bovine tuberculins. In the SICTT, each countries have used with different combination of both avian and bovine tuberculins' titers. However, this kinds of studies have not reported in Korea. Therefore, the studies on the combination of their tuberculins' titers were performed through intradermal test of guinea pigs sensitized with either Mycobacterium bovis or M avium and were examined in 10 cattles of SIT positive reactors. Also, IFN-${\gamma}$ assay, the latest diagnostic method of bovine tuberculosis, was experimentally applied to SIT positive reactors. For determining the optimal titers, sensitized guinea pigs with M bovis and M avium were intradermally injected avian and bovine tuberculin. In guinea pigs sensitized with M bovis, bovine tuberculin 50 T.U. showed significant difference from all tested concentrations of avian tuberculin(p < 0.05). In guinea pigs sensitized with M avium, there is significantly different between bovine tuberculin and avian tuberculin by 25 T.U.(p < 0.01). Therefore, optimal titers of bovine and avian PPD tuberculins' titers for the SICTT in Korea were 5,000 and 2,500 tuberculin units, respectively, and the swelling diffences between bovine and avian site in SIT positive reactors were above 3mm. Also, in IFN-${\gamma}$ assay, the 9 SIT positive reactors were showed all the positive reactions.

The purpose of this study was to investigate the effects of mineral taping containing natural minerals powder on knee joint pain and swelling in the elderly. Forty elderly people with knee pain were divided into 20 mineral taping groups and 20 kinesio taping groups and randomly placed in a single blind manner. The study period was conducted from April 6, 2020 to April 7, 2020, and pain and blood flow by time point were examined before, after, and after 1 day of taping. Knee pain was significantly different in the post-test (F = 93.758, p <.001) and the post-day test (F = 93.758, p <0.001) for each measurement point. The blood flow test for edema was significantly different in the post-test (F = 48.648, p <0.001) and the post-day test (F = 35,427, p <0.001) for each measurement time point. There was no significant difference in the effect test result for each group (F = 0.160, p> 0.05). However, When comparing the retention effect after 1 day, the mineral taping group was excellent to the post-score than the Kinesio taping group. In the future, we believe that increasing the taping time and retention period will have a positive effect. It is thought that the results of this study will contribute to the study of taping materials in the future.

Purpose: Biphasic calcium phosphate (BCP), a widely used biomaterial for bone regeneration, contains synthetic hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP), the ratio of which can be adjusted to modulate the rate of degradation. The aim of this study was to evaluate the clinical and radiographic benefits of reconstructing peri-implant bone defects with a newly developed BCP consisting of 60% β-TCP and 40% HA compared to demineralized bovine bone mineral (DBBM). Methods: This prospective, multicenter, parallel, single-blind randomized controlled trial was conducted at the periodontology departments of 3 different dental hospitals. Changes in clinical (defect width and height) and radiographic (augmented horizontal bone thickness) parameters were measured between implant surgery with guided bone regeneration (GBR) and re-entry surgery. Postoperative discomfort (severity and duration of pain and swelling) and early soft-tissue wound healing (dehiscence and inflammation) were also assessed. Data were compared between the BCP (test) and DBBM (control) groups using the independent t-test and the χ² test. Results: Of the 53 cases included, 27 were in the test group and 26 were in the control group. After a healing period of 18 weeks, the full and mean resolution of buccal dehiscence defects were 59.3% (n=16) and 71.3% in the test group and 42.3% (n=11) and 57.9% in the control group, respectively. There were no significant differences between the groups in terms of the change in mean horizontal bone augmentation (test group: -0.50±0.66 mm vs. control groups: -0.66±0.83 mm, P=0.133), postoperative discomfort, or early wound healing. No adverse or fatal complications occurred in either group. Conclusions: The GBR procedure with the newly developed BCP showed favorable clinical, radiographic, postoperative discomfort-related, and early wound healing outcomes for peri-implant dehiscence defects that were similar to those for DBBM.

The main purpose of this study is to estimate the effect of adding Tea-N-Tris (TES) to the freezing buffer for miniature pig sperm. In particular, we attempted to identify the association between the MMPs expression and the fertility and viability of frozen sperm from each extender (LEY (Lactose Egg-Yolk), TLE (TES + LEY), TFGE (TES + Fructose + Glucose Egg-Yolk)). In accordance with this, Hypoosmotic Swelling Test (HOST) respond test was the lowest among sperms frozen in LEY while the highest HOST respond was observed among sperms frozen in TLE. Furthermore, we observed MMPs expression in all sperm groups, with pro-MMP showing lower expression than active MMPs. The expression of MMP-9 and MMP-2 was the highest in sperms frozen in LEY, Meanwhile, sperms from the TFGE and TLE group showed lower level of MMP-9 and MMP-2 expression in the order of TLE being the lowest. LEY group showed lower rate of blastocyst development than the TES supplement group, although the difference was not statistically significant. Meanwhile the rate of blastocyst development appeared similar when sperms from TLE and TFGE group were used for IVF. Together, these results indicate that adding Tea-N-Tris to the sperm freezing buffer only suppresses MMPs protein activation but also maximize in-vitro fertility, providing a means to improve the success rate in the in vitro manipulation of miniature pig sperm.

Vancomycin-resistant enterococcus(VRE) was first isolated from various specimens of patients with renal failure or leukemia in 1988. Thereafter VRE has been increasing gradually and became one of the clinically important palhogenic organisms currently. We experienced a case of E. faecalis sepsis in a 4 day old neonate. She was born at 39 weeks gestational age with 2,900gm weight by Cesarean section delivery due to breech presentation. She had had swelling and motion limitation of the left knee joint with fever for one day at age of 4 day and was transfered to our hospital. Ultrasonographic examination of her left knee joint showed some inflammatory change. E. faecalis was isolated from the blood. The organism showed resistance to vancomycin on drug susceptibility test using BHI agar screening test and disk diffusion method. After treatment with ampicillin-sulbactam for 3 weeks the baby was improved. Although VRE infection has been considered rare in Korea. considerable number of demonstrative studies about VRE isolation have been reported recently thus adequate countermeasures are needed to reduce the emergence and prevent nosocomial spreading of this organism.

Acute transverse myelitis is a focal inflammatory disorder of the spinal cord, resulting in motor, sensory, and autonomic dysfunction which would be the initial manifestation of acute disseminated encephalomyelitis. A 7-year-old boy developed weakness of lower extremities associated with dizziness and urinary dysfunction after upper respiratory infection. He showed gradual decreased mental status with respiratory difficulty. Spinal MRI showed diffuse spinal cord swelling from C3 to C7 levels with high signal intensity lesion on T2-weighted image, which is involved central gray matter of spinal cord from C3 to C7, proximal portion to cervicomedullary junction, and distal portion to the cornus medullaris. After the supplement of high dose intravenous methylprednisolone therapy with ventilator care, he showed gradual improvement. The brain MRI after extubation showed multifocal high signal intensity lesions in bilateral cerebral white matter on axial T2-weighted image. Immunoserologic test(neutral antibody test) for enterovirus 71 was positive. Dysfunction of the bladder lasted for 33 days. We report a case of transverse myelitis which progressed to acute disseminated encephalomyelitis by enterovirus 71 in a 7-year-old boy with related literatures.

Marine dredged soils taken from navigation channels or construction sites of coastal area usually have a lot of salt in pores of clayey soils. This paper investigates effect of salt on mechanical characteristics of non-salt and salt-rich stabilized dredged soil. The stabilized dredged soil (SDS) consisted of dredged soil and cement. Several pairs of SDS with non-salt and salt-rich dredged soils, noted as N-SDS and S-SDS, respectively, were prepared to compare their strengths and compressibility characteristics. The microstructures, strength and compressibility characteristics of N-SDS and S-SDS specimens at 7 and 28 days of curing time were evaluated using scanning electronic microscope (SEM), unconfined compression test, and oedometer test. It was found that salt concentration of clayey soil affected not only the formation of soil structure but also the strength development of mixture. The compression index and swelling index of S-SDS were also greater than those of N-SDS, which indicated that the compressibility of mixture increased due to salt concentration. Salinity in clayey soil had a negative effect on the strength development and compressibility characteristics of stabilized dredged soils.

In order to improve the final product quality, tobacco industry has gradually decreased the size and number of steams in the cigarette. Especially, steams bigger than $3{\times}3$ mm($length{\times}thickness$) and $2{\times}10$ mm($width{\times}length$) are not acceptable in the process as objectionable stems. A total number of 12 samples where the $length{\times}tickness$ samples were prepared by decreasing the present sample ($3{\times}3$ mm) with 1 mm up to $1{\times}1$ mm, and the $width{\times}length$ samples were prepared by decreasing the present sample ($2{\times}10$ mm) with 2 mm up to $2{\times}6$ mm for the stems in leaf and stems in expanded cut-tobacco were prepared to apply a fire ball drop test using stems. In addition, cigarettes were produced for these stems in order to analyze the forced fire ball drop including the burning, encapsulation and unencapsulation pressure drop and a single or unspecified direction combustion. Based on the results of the test, it was evident that the fire ball drop in the stems in expanded cut-tobacco presented a lower level than that of the stems in leaf. Also, the stems in expanded cut-tobacco presented a larger swelling and higher burning for a single direction than that of the stem in leaf. In addition, it was considered that the management criteria for objectionable stems should be changed as $3{\times}3$ mm and $2{\times}8$ mm for the $length{\times}thickness$ and $width{\times}length$ sample, respectively, in both steams in leaf and expanded cut-tobacco.

To evaluate the engineering characteristics of aggregate base materials, cyclic triaxial, CBR and permeability tests were performed for 15 samples. The CBR values of aggregate base materials have wide range from 32 to 110(average 81) and the amount of swelling in submerged conditions has below 0.04mm. The Modulus of aggregate base materials were significantly affected by volumetric stress, linear volumetric model was best for fitting. The modulus of aggregate base materials were determined within range of 100MPa~600MPa, 80~270 and 0.1~0.6 for model coefficient $k_1$ and $k_2$ respectively. The empirical correlation model was suggested that prediction the modulus from the basic properties obtained from particle size distribution test and compaction test. The coefficient of determination of the proposed correlation model was 0.423 for model coefficient $k_1$, 0.920 for model coefficient $k_2$ and 0.872 for modulus with stress level.
