Seriousness of particulate matter (PM 2.5, 1.0, 0.1) leads to rigid regulation in atmospheric field due to class 1 cancer-causing agent. Noteworthy fact that most particulate matter is generated by gaseous contaminants is high conversion proportion by nitrogen oxides (NOx) among them. Therefore, selective catalytic reduction (SCR) technology is indispensable for decomposing NOx into harmless products, N₂ and H₂O, because it is also harmful to both environment and living organisms itself. Conventional production process of SCR catalyst use extrusion for honeycomb shape, but it has difficult to rapidly fabricate diverse and complex morphology for improved performance. It is possibly solved by replacing extrusion to 3Dprinting having advantages such as effective short process time, effective economy aspect, and recycle of materials. In this study, catalyst carrier that is manufactured by 3D-printing is coated with SCR slurry of V₂O5-WO₃/TiO₂, commercial composition. Subsequently, performance and properties are characterized by particle size, morphology, catalytic performance in powder and green body state.

The purpose of this study is to investigate a loosening process of screws through a fatigue test. Therefore, it is attempted to perform an interbody fusion on porsine lumbar spine using cage and screws. From the results, it is found that the combining force in both of the cylinder and the taper type screws located on the upper-left first start to decrease and then the combination between a rod and screw loosens. In addition, it is investigated that the life of taper type screw increases 5.5% and this fact is coincident with the previous results.

Purpose: The purpose of this study was to compare college students’ cyber sex, sexual knowledge and sexual autonomy according to their use of random-chatting application. The objective was to analyze the relationship among cyber sex, sexual knowledge and sexual autonomy. Method: The method used in the study was a descriptive correlation study. The subjects were 476 college students. 258 students of them answered to have used random-chatting application and 216 students to have not. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Chi-square test, Scheffe test and pearson correlation using the SPSS 21.0 program. Result: The results of this study were the following: 1. Among 476 subjects, 258(54.20%) of them have used random chatting application, 46(9.66%) of them have shared sexual conversation or pictures through the application, and 68(14.29%) of them have met the opposite sex in person through the application. 2. Concerning the usage of random chatting application, students who have used the application have recorded a higher cyber sex score than students who haven’t. (t=-9.457, p<.001). 3. For students who have used random chatting application, there was a negative correlation between the cyber sex score and sexual knowledge (r=-.13, p=.034). Also, there was a positive correlation between sexual autonomy and sexual knowledge (r=.19, p=.003). Conclusion: It was revealed that the use of random chatting application has a high relevance to cyber sex addiction. Considering the fact that the use of the application has little to do with sexual knowledge and sexual autonomy, it is necessary that appropriate sex-education be offered and some programs to increase sexual autonomy be developed. The new sex-education should include some contents related to the random chatting application which can be used for sexual purposes

The objectives of this study were to develop polyclonal antibody to adipocyte plasma membrane(APM) proteins isolated from Korean native cattle, and to investigate its tissue specificity. Plasma membrane proteins from adipocyte, liver, heart, spleen, and kidney were isolated using a self-forming percoll gradient. Sheep(40∼50㎏) was immunized three times at three week interval with the purified APM proteins. Blood was taken from immunized sheep at 10(AS-1), 12(AS-2), and 14(AS-3) days after the third immunization. Antisera titers and cross-reactivity against other tissues were determined by enzyme-linked immunosorbent assay(ELISA). Antisera reacted strongly to the APM proteins showing detectable amounts of antibody at 1:81,000 dilution. The antisera reacted to APM proteins specifically whereas they showed no reactivity to any other tissue plasma membrane proteins. Furthermore, tissue specificity of antisera against APM proteins was reconfirmed by immunoblotting using anti-sheep immunoglobulin G-peroxidase conjugate as a second antibody. The antisera to APM proteins showed adipocyte specificity compared to other tissues. In conclusion, polyclonal antibody against APM proteins isolated from Korean native cattle was developed successfully, and these antisera showed the specific reactivity with APM proteins.
