We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

Aims: We aimed to evaluate the efficacy and safety of Daclatasvir (DAV) and Asunaprevir (ASV) in patients with chronic hepatitis C virus (HCV) and chronic renal failure (CRF). Methods: 22 chronic hemodialysis patients with HCV infection at 12 medical centers have prospectively enrolled from Feb, 2016 to Feb, 2017 (NCT02580474). Of those, 9 patients who were followed 12 weeks after treatment ended were included. We evaluated the virological responses at each week 4, 12, 24 and the 12-week sustained virologic response (SVR12). The tolerability and safety of patients were also evaluated. Results: Of these 20 patients, there had no resistance-associated variant of NS5A (NS5A RAVs) and 2 patients showed indeterminate NS5A RAVs. 12 patients (54.5%) completed the 24 weeks treatment of DAV and ASV. 6 patients (27.2%) have continued, but 4 patients discontinued study prior to 12 weeks. Overall, all patients (n=9) achieved SVR12. Virologic response at week 4, 12 and 24 showed 94.4% (17/18), 93.3% (14/15), and 100% (12/12) respectively. DCV and ASV were well tolerated among the majority of patients and discontinuation of the treatment due to adverse events (hypertension, bradycardia, leukemia) was occurred in 3 patients. In two patients with indeterminate NS5A RAVs, one achieved SVR12 but the other showed viral breakthrough and discontinued treatment. Conclusions: In this study, DAV and ASV combination therapy for chronic hemodialysis patients with HCV infection achieved high sustained virological response with few adverse events. Close monitoring of safety and tolerability may be necessary when treating chronic hepatitis C patients with CRF receiving DCV and ASV.

이 연구는 제20대 대통령 선거의 소셜 미디어 선거 캠페인에 대한 대중들의 반응을 사회연결망분석을 이용해 살펴보았다. 구체적으로 유튜브 채널 ‘삼프로TV: 경제의 신과 함께’에 게시된 2022년 대통령 선거 후보자 토론 영상과 댓글을 수집하였다. 수집된 데이터를 기반으로 댓글 이용자 연결망 구조를 확인하기 위한 사회연결망분석, 댓글 이용자의 어휘 다양성 파악과 핵심이슈 파악을 위한 의미연결망분석을 수행하였다. 그 결과, 이재명 후보의 연결망이 윤석열 후보에 비해 이용자들 간 밀집도가 더 높았다. 어휘 다양성에 있어서는 윤석열 후보 영상 댓글이 더 다양한 어휘를 구사하는 것으로 나타났다. 이로써 영상 댓글 이용자들 간 ‘관계’에 초점을 두었을 때는 이재명 후보자의 영상이 윤석열 후보에 비해 더 집합적(collective)이었으나, 어휘의 다양성 측면에서 보았을 때는 윤석열 후보가 더 결합적(connective)인 것을 알 수 있다. 핵심 이슈의 경우, 이재명 후보는 후보자 발언에 대한 이용자의 생각이 주로 나타났고, 윤석열 후보는 후보자에 대한 평가나 비판의 내용이 나타났다. 이 연구는 ‘말’보다 ‘행동’에서 비롯된 데이터의 중요성과 약한 유대의 힘 이론이 설명력을 지니고 있음을 시사한다. Using social network analysis, this study investigated people’s responses to Youtube-mediated debate during the 2022 presidential election in Korea. Videos and comments, that were uploaded on the YouTube channel “Sampro TV: With the God of Economy”, were collected using Webometric Analyst 2.0 software. Several network techniques was performed on the obtained data to uncover the structure of the comment user network, and a semantic network analysis was also performed to identify the linguistic diversity of comment users and to identify critical issues. As a result, candidate Lee Jae-Myung’s network had a greater user density than candidate Yoon Suk-Yeol’s network. Yoon Suk-Yeol’s video comments were found to employ more diversified terminology. As a consequence, when focused on the strength of relations between video comment users in a core group, Lee Jae-Myung’s video was more collective and communal than Yoon’s, although Yoon is more connective in terms of vocabulary diversity. In the case of major issues, Lee’s commenters mostly displayed their supporting thoughts on his discussions, whereas Yoon’s commenters displayed the contents of evaluation or critique. The findings of this study is discused from a perspective of the strength of weak ties in social networks.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

A 4 years old, mixed male dog with a history of traffic accident was presented to the Veterinary Medical Teaching Hospital of Chungnam National University with tachypnea and respiratory distress. Physical examination showed that the dog was auscultated crackles sounds, dysynchronous abdominal breathing pattern, hemoptysis, hematuria, urodynia and right and left scleral congestion. Blood and blood chemical examination revealed that WBC, AST and ALT was highly elevated. Parenchymal pulmonary fluid and closed pneumothorax were observed by thoracic radiography. This case was diagnosed as pulmonary contusion. Intravenous fluid and oxygen was administered and also dexamethasone(1mg/kg, Ⅳ), furosemide(2mg/kg, Ⅳ), (ampicillin, 20mg/kg, Ⅳ) and meloxicam(0.2mg/kg, PO) were intravenously injected for 5 days. Abnormal clinical signs were disappeared after treatment.

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.

Objective: Currently, normal data of cervical disc height and depth of Korean adults are not available. The objective of this study is to compile a Korean normative database of the disc height and depth of the cervical spine, valid for healthy Korean adults. Methods: All the volunteers were attached a coin on the anterior midline of the neck. From the lateral X-ray films of the cervical spine, anterior and middle disc height and anteroposterior disc depth from C2-3 to C6-7 were measured. The magnification of radiographic films as compared with real measurement of the coin was taken into consideration. Analysis of data was done by use of independent sample t-test, Pearson's correlation, and one-way analysis of variance(ANOVA). Results; A normal database for the dimensions of cervical discs was compiled from 42 lateral views of healthy Korean adults. There were 20 males(mean age, 29,6 years; mean height, 174.3 cm) and 22 females(mean age, 27,4 years; mean height, 161.2 cm). The means of anterior height, middle height and anteroposterlor depth of cervical disc space were 4.09mm, 5,82mm, and 16,86mm for men and 3,40 mm, 5.30 mm, and 14.86 mm for women, respectively, The height of C4-5 disc space was highest at the middle disc space from C2-3 to C6-7. Conclusion: This study will contribute to the clinical diagnosis, treatment and development of instruments of cervical disc diseases for Korean patients with cervical disc diseases.

This paper propose a new path planning method for mobile robots. The creation method of the course approaches with the method of the frame line graph base where the calculation time becomes disturbance. The graph composition where is not the static course plan method of existing, a course search and repeats continuously changes a graph and proposes the course the dynamic routing plan method. The method which is proposed is composed of a course creation phase and a course improvement phase, each phase includes a graph composition and a course search process.
