This study was performed to evaluate the effects of ocular bacteria and tear lactoferrin on the Tear Staining Syndrome(TSS) in poodle dogs. Staphylococcus, Klebsiella, Micrococcus and Pseudomonas were the most Prevalent microorganisms isolated in normal eyes of poodle dogs, whereas the predominant isolates in the poodle dogs with TSS were Micrococcus, Staptococcus and Staphylococcus. There were no significant differences between the normal and tear-stained poodle dogs in the quantity of tear lactoferrin. In vitro hair staining experiment, bacteria isolated from the eyes with TSS and lactoferrin didn't stain hair. The results have shown that either ocular bacteria or tear lactoferrins were not related to the TSS.

해상교통관리 방법 중에서 국내외적으로 혼잡한 해역에서의 해상교통 흐름을 정류하여 통항선박의 해상교통 안전성을 향상시키는 방법 중 주로 이용되고 있는 것은 항로 설정 및 통항분리대의 설정이다. 항로 및 통항분리대의 설정 시 지침이 되는 설계지침 가운데 국내외적으로 항로 설계지침은 존재하지만 통항분리대에 대한 설계지침에 대한 언급은 어느 문헌에도 없어 전문가의 주관적 판단에 의하여 설정이 되고 있는 실정이다. 현재까지 통항분리대의 설정 시 해양사고의 감소효과에 대한 연구는 다소 있지만, 통항분리대의 설계지침에 대한 연구는 없다. 본 연구는 통항선박의 안전을 위하여 설정되는 통항분리제도에 대한 설계지침을 선박 운항자의 관점에서 본 정량적 수치로 제공하고자 한다. 특히 통항분리대는 많은 선박의 통항을 분리하기 위한 제도이기 때문에 통항하는 선박의 교통용량을 고려하여 설계하였다.

Due to climate change, coastal areas are being flooded with torrential rain, typhoons, and tsunamis. In addition, non-point source pollutants (NPSs) that accumulated on the ground, streets, and buildings during the dry season are washed off by rain and stormwater runoff, which adds to the damage associated with environmental pollution, e.g., pollution that makes its way into the ocean. Recently, low impact development (LID) has been considered as a means of controlling water circulation and NPSs. In the coastal area, permeable blocks have been constructed mainly to reduce the flood damage caused by waves. Some important design factors that must be considered to ensure long-term performance are the permeability coefficient, clogging, and the efficiency of the removal of total suspended solids (TSS), but currently there are no standardized design criteria or testing techniques that are used worldwide. Herein, we analyzed the permeability coefficient and the TSS removal efficiency tendency according to the permeability area ratio with an easily-detachable, permeable block filled with calcinated yellow soils as the filter media. Our lab-scale tests indicated that, when the permeability area ratio was 25%, the reduction of the permeability coefficient after clogged was 11%, which was a significant decrease compared to other cases. Permeability persistence increased when the permeability area ratio increased from 50% to 75%. The TSS removal efficiency decreased as the permeability area ratio increased. Our pilot-scale test indicated that the TSS removal efficiency was more than 80% higher in all cases. We also found that the permeability persistence was excellent as the permeability area ratio increased, and, in actual construction, it is effective to set 5.3% of the total area as permeable area in terms of permeability and economic feasibility.

Sediment flow through hydropower components causes hydro-abrasive erosion resulting in loss of efficiency, interruptions in power production and downtime for repair/maintenance. Online instruments are required to measure/capture the variations in sediment parameters along with collecting samples manually to analyse in laboratory for verification. In this paper, various sediment parameters viz. size, concentration (TSS), shape and mineral composition relevant to hydro-abrasive erosion were measured and discussed with respect to a hydropower plant in Himalayan region, India. A multi-frequency acoustic instrument was installed at a desilting chamber to continuously monitor particle size distribution (PSD) and TSS entering the turbine during 27 May to 6 August 2015. The sediment parameters viz. TSS, size distribution, mineral composition and shape entering the turbine were also measured and analysed, using manual samples collected twice daily from hydropower plant, in laboratory with instruments based on laser diffraction, dynamic digital image processing, gravimetric method, conductivity, scanning electron microscope, X-ray diffraction and turbidity. The acoustic instrument was able to capture the variation in TSS; however, significant deviations were found between measured mean sediment sizes compared to values found in the laboratory. A good relation was found for turbidity ($R^2=0.86$) and laser diffraction ($R^2=0.93$) with TSS, which indicated that turbidimeter and laser diffraction instrument can be used for continuous monitoring of TSS at the plant. Total sediment load passed through penstock during study period was estimated to be 15,500 ton. This study shall be useful for researchers and hydropower managers in measuring/monitoring sediment for hydro-abrasive erosion study in hydropower plants.

Objectives : This study was to observe the nephroprotective effects of the traditional prescription, Taeksa-san(TSS). TSS has generally been used for treating various renal diseases, including renal failure. Methods : Three different dosages of TSS extract were orally administered once a day for 28 days, At the 23rd day after TSS extract treatment, cisplatin was also treated. Then, 5 days after cisplatin treatment, all the rats (6 groups of 8 rats each) were sacrificed. Changes in the body weight, kidney weight, serum BUN and creatinine levels were observed with changes on the kidney MDA and GSH contents. The results were compared with captopril 100mg/kg, of which the effects on cisplatin-induced acute renal failures are already confirmed. Results : Dramatic decrease of body weight, increase of kidney weight, increase of serum BUN and creatinine levels were detected in the cisplatin control as compared with the intact control. In addition, marked increase of kidney MDA contents and decrease of kidney GSH contents were also detected in the cisplatin control as compared with the intact control. This means that cisplatin-induced ARF is induced by oxidative stress and related lipid peroxidation in the present study. However, these ARFs and inhibition of antioxidant effects induced by cisplatin were dose-dependently reduced by treatment with all three different dosages of TSS extracts. Conclusion : This study suggests that TSS extracts show favorable effects on cisplatin-induced rat ARF.

Total suspended solids (TSS), settleable suspended solids (SSS) and nonsettleable suspended solids (NSSS) were compared in streams and lakes during rain events. Samples were collected in Lake Soyang and nine agricultural streams during storm events over two years. To measure NSSS, samples were settled in 1 L cylinders for one hour and then 50% of the total sample volume was taken from the center of the cylinder. The SSS/TSS ratio in streams (0.50) was higher than in Lake Soyang (0.20). The ratio of TSS to turbidity decreased from 1.21 in the inflowing river to 0.69 in the reservoir outlet. Turbidity and NSSS showed higher correlation ($r^2$=0.82) compared with the correlation between turbidity and TSS ($r^2$=0.66). Median particle size decreased from $11.4\;{\mu}m$ in the inflowing river to $4.2\;{\mu}m$ in the lake outlet. The results indicate that only fine particles of less than $5{\sim}10\;{\mu}m$ can be transported downstream of the lake. Because fast-flowing water in streams includes not only fine particles but also coarse particles, an overestimation of suspended sediment concentration results if only TSS is measured. Consequently, TSS and NSSS should be measured separately to evaluate the effect of suspend sediment loadings of turbid streams on aquatic habitat during the monsoon season.

It has been reported that exogenously introduced micro-RNA (exo-miRNA) competes with endogenously expressed miRNAs (endo-miRNAs) in human cells, resulting in a detectable upregulation of mRNAs with endo-miRNA target sites (TSs). However, the detailed mechanisms of the competition between exo- and endo-miRNAs remain uninvestigated. In this study, using 74 microarrays that monitored the whole-transcriptome response after introducing miRNAs or siRNAs into HeLa cells, we systematically examined the derepression of mRNAs with exo- and/or endo-miRNA TSs. We quantitatively assessed the effect of the number of endo-miRNA TSs on the degree of mRNA derepression. As a result, we observed that the number of endo-miRNA TSs was significantly associated with the degree of derepression, supporting that the derepression resulted from the competition between exo- and endo-miRNAs. However, when we examined whether the site proficiency of exo-miRNA TSs could also influence mRNA derepression, to our surprise, we discovered a strong positive correlation. Our analysis indicates that site proficiencies of both exo- and endo-miRNA TSs are important determinants for the degree of mRNA derepression, implying that the derepression of mRNAs in response to exo-miRNA is more complex than that currently perceived. Our observations may lead to a more complete understanding of the detailed mechanisms of the competition between exo- and endo-miRNAs and to a more accurate prediction of miRNA targets. Our analysis also suggests an interesting hypothesis that long 3'-UTRs may function as molecular buffer against gene expression regulation by individual miRNAs.
