Assay for the detection and quantification of porcine circovirus type 2 (PCV 2) with the real-time PCR were developed. TaqMan probe real-time using a set of primer/probe was developed for detection of PCV 2. In this study we applied real-time PCR assay to 320 samples, collected from pig farms. In 151 of 320 samples, PCV 2 DNA was detected by conventional PCR assay. All samples positive for PCV 2 DNA in conventional PCR assay were also positive in Real-time PCR assay, but 69 of 169 samples that tested negative for PCV 2 DNA in conventional assay were tested positive in TaqMan probe real-time PCR assay. The test of TaqMan probe real-time PCR resulted in detection and quantification limits of 101 copies per sample. TaqMan probe real-time PCR assay increased the number of samples in which PCV 2 was detected by 21%. TaqMan probe real-time PCR assay is very efficient method in contrast to the conventinal PCR, becoming increasingly important method for gene analysis.

This paper presents a mechanism for improving performance of the IEEE 802.6 MAN(Metropolitan Area Network), a dual-bus structured high-speed communication network, by a more efficient use of bandwidth. The MAN protocol is able to handle various traffic and offers better transmission speed than the conventional LAN, but the unidirectional bus structure and propagation delay of request bits results in unfairness since higher nodes use more bandwidth. As the number of stations and the distances between them are increased, the problem becomes mere serious. As a solution, this paper presents a method that every station enables to identify the used slots, and that a specified class denoted 'erasure station' has with the functions of destination release, slot reuse. As a result, it is export to improve network bandwidth values of each station and the throughput and delay time was analytically analyzed, and it is shown that according to computer simulation results, this mechanism improves the network performance.

In the IEEE 802.16 Wireless MAN standard, the best effort service class is ranked on the lowest position in priority and is assisted by a MAC scheme based on reservation ALOHA. In such a MAC scheme, a collision among the requests is unavoidable so that the standard adopted a binary exponential back-off rule to arbitrate a collision. Aiming at improving throughput performance, we present two generic collision arbitration rules based on p-persistence rule, (identified as pristine and metamorphosed rules), as alternatives in a wireless MAN. For each of these rules, we then develop an analytical method to calculate an approximate value of saturated throughput. In comparison with simulation results, we confirm the high accuracy of the analytical method. Also, the pristine and metamorphosed rules are observed to exhibit higher saturated throughput compared with the binary exponential back-off rule.

This study is focused on a space for man in upper classes house that is one of appeared characteristics as Korea, China and Japan imported Confucianism become common cultural base in these countries. Because a space for man in these countries has the same nature represented as a typical space in a upper classes house, and this space is differentiated by regional features, a way of thinking, a way of life and social structure as well, these characteristics are compared one another. Import of Confucianism influenced formation of a upper classes house and the spaces of the house are divided by generation, sexuality and classes. A space for man become a center of the house as well as a space for reception in accordance with patriarchism because this space stands for hierarchy of the house. A space for man of each country, Korea, China and Japan, has differences; that is, Chinese Jeongbang is used as a space for family as well as for guests; Korean Sarangchae is for only men and used as a reception space; Japanese Zasiki is used just for reception. These differences among countries are caused by owner's class, a civil officer or a military officer, and this class differentiated the characteristics of reception for guest. Even though the these countries take the space for man for meeting, Chinese is for family, Korean is for ancestors and Japanese is for guests.

Since the first episode of (1995) by Pixar, a world leading animation company, 3D animation has been focused on realistic motion and rendering techniques. However, in 2018, 3D animation was released, with unique backgrounds created through illustration techniques and dynamic movements of characters that seemed to be produced by hand rather than computers. It shows a lot of difference from other 3D animations. In this study, I analyzed 's new production techniques and expressions into two categories, first, the use of old comics techniques, and second, other factors that made the animation stand out. in 3D animation market focused on realistic motion and rendering techniques can have positive implications in terms of expanding animation diversity. This study is expected to be used as academic or research data for researchers studying new production techniques in related fields.

Culture is the gold standard for diagnosis of tuberculosis, but it takes 6 to 8 weeks to confirm the result. This issue is complemented by the detection method using polymerase chain reaction, which is now widely used in a routine microbiology laboratory. In this study, we evaluated the performance of the Seegene Anyplex TB PCR to assess its diagnostic sensitivity and specificity, and compared its results with the Roche Cobas TaqMan MTB PCR, one of the most widely used assays in the world. Five university hospitals located in the Chungcheong area in South Korea participated in the study. A total of 1,167 respiratory specimens ordered for acid-fast bacilli staining and culture were collected for four months, analyzed via the Seegene Anyplex TB PCR, and its results were compared with the Roche Cobas TaqMan MTB PCR. For detection of Mycobacterium tuberculosis, the diagnostic sensitivity and specificity of the Anyplex TB PCR were 87.5% and 98.2% respectively, whereas those of the Cobas TaqMan were 92.0% and 98.0% respectively (p value > 0.05). For smear-positive specimens, the sensitivity of the Anyplex TB PCR was 95.2%, which was exactly the same as that of the Cobas TaqMan. For smear-negative specimens, the sensitivity of the Anyplex TB PCR was 69.2%, whereas that of the Cobas TaqMan TB PCR was 84.6%. For detection of MTB, the Seegene Anyplex TB PCR showed excellent diagnostic performance, and high sensitivity and specificity, which were comparable to the Roche Cobas TaqMan MTB PCR. In conclusion, the Anyplex TB PCR can be a useful diagnostic tool for the early detection of tuberculosis in clinical laboratories.

In this paper, I will show several theoretical nonconformities which can be found in P. Singer's concept of human beings. As we know, P. Singer is a well-known animal liberalist. On the one hand, Singer regards man as a subordinate being to nature and on the other, as a transcendent being. This is the first inconsistency of Singer's concept of man. His second inconsistency is related to his position on the power of reason. He believes that it is the product of evolution, and at the same time that it is a power to resist the blindness of evolution. Thirdly, he also exposes the contradictory attitude in evaluation on man's moral ability. Considering these three contradictions, it becomes clear that Singer has failed to prove his claim that there is no qualitative difference between human beings and animals. Despite the popularity of his theory, I believe the theoretical foundation of Singer's animal liberation theory is rather weak. The reason for revealing the weakness of Singer's theory is not to return to the practice of mercilessly handling animals but to show that it is wrong to undermine human dignity under the guise of animal welfare.

This study aimed to identify the relationship between perfectionism and motivational climate in competitive athletes and to provide information for improvement of their performance. One hundred ninety-six athletes who trained in Korea National Training Center participated in this study and they were divided into record and man-to-man events. Also they filled in the questionnaire about demographic factors, perfectionism, and motivational climate. Collected data were analyzed by using cross validation and independent t-test for identifying the difference of two events and structural equation model for testing hypotheses and model fit. Perfectionism and motivational climate in man-to-man events were stronger compared to record event. In record event, perfectionism was more influenced by ego involving motivational climate compared to task involving, while in man-to-man event, perfectionism was affected by only ego involving motivational climate. However, these both study models had a bad fit.

This study presents the superiority of his calligraphy by analyzing the use, meaning, and calligraphy of nickname three dragon-man(yong-jeong) written by Kim Junghee before and after exile in Jeju Island. Based on the basic structure of the three dragon-man, the relationship between the times, the context, and the characters was studied. Through this change process, the difference of art engineering with other works was analyzed. Kim Junghee intentionally went through a difficult situation by using a nickname with a dragon. He wrote different meanings, uses, and typefaces of the nickname three dragon-man, depending on the circumstances. Finally, Kim Junghee used 'three dragon-man' to King Heonjong and Monk Choui to express his feelings and intentions. His writing was excellent in art engineering and unique in the world. All were found to be supported by his epigraphy insights. The results of this study will be a new methodology for analyzing the meaning of nicknames of ordinary artists.

In this paper, we propose an algorithm that enables near-field delivery at a faster and lowest cost to meet the growing demand for delivery services. The algorithm proposed in this study involves subway passengers (shipper) in logistics movement as delivery sources. At this time, the passenger may select a delivery logistics matching subway route. And from the perspective of the service user, it is possible to select a delivery man whose route matches. At this time, the delivery source recommendation is carried out in a text similarity measurement method that combines TF-IDF&N-gram and BERT. Therefore, unlike the existing delivery system, two-way selection is supported in a man-to-man method between consumers and delivery man. Both cost minimization and delivery period reduction can be guaranteed in that passengers on board are involved in logistics movement. In addition, since special skills are not required in terms of transportation, it is also meaningful in that it can provide opportunities for economic participation to workers whose job positions have been reduced.
