본 연구는 임상형 및 준임상형 유방염에 이환된 젖소의 유즙에서 분리된 24주의 황색포도상구균에 대한 capsular polysaccharide(CP)형을 확인하고, 1% 토끼 혈청이 함유된 serum-soft agar 배지에서 집락의 모양을 관찰하였다. 또한 동물에 따라 우세한 CP형의 차이가 있는지를 비교하고자 개에서 분리된 13주에 대하여 동일한 실험을 수행하여 다음과 같은 결과를 얻었다. 집락모양을 관찰한 결과 젖소 유래 24주 중 16주(66.7%)는 diffuse, 5주(20.8%)는 compact, 나머지 3주(12.5%)는 분류가 불가능(indeterminate)하였다. CP형 확인결과 9주(37.5%)는 type 5, 2주(8.3%)는 type 8, 13주(54.2%)는 분류가 불가능(non-typeable)하였다. 한편, 개에서 분리된 균주 중 1주(type 8)를 제외한 12주(92.3%)는 type 5로 분류되었으며, 13주 중 8주(61.5%)가 diffuse형의 집락을 보였다. 본 실험에 사용한 균주의 수가 충분하지 못한 문제가 있지만 동물에 따라 우세한 CP형이 다를 수 있으며 분류 불가능한 균주가 상대적으로 높은 비율을 차지하였는데 이는 새로운 CP형의 분류형이 필요함을 시사하는 것으로 판단된다. 또한 type 5와 type 8만을 포함한 유방염 백신은 한계가 있을 것으로 사료된다.

Immediate implantation is widely applied as it is recognized as a useful implant treatment in dental clinic due to its various advantages as well as being able to shorten the treatment period. Immediate implant treatment was performed on 5 patients who needed extraction of the mandibular first molar for various reasons, shortening the overall treatment period, and obtaining satisfactory results. Immediate implantation after extraction is a high-level treatment that requires proper initial fixation at the exact location of the extraction socket and the surrounding soft tissues, but is considered to be a clinically very useful prosthetic restoration method

A 14-year-old gelded dressage horse weighing 500 kg was presented to the Equine Medical Center of the Seoul Racecourse of Korea Racing Authority (KRA) due to coughing and mucopurulent nasal discharge. The horse was initiated with empirical antibiotic in the first place. However, the clinical signs did not improve but were rather exacerbated even after 3 weeks of therapy. Extensive diagnostic procedures including transtracheal wash (TTW) fluid cytology were undertaken. The localized wheezes and crackles were auscultated and an increase in the amount of mucopurulent exudate in trachea was observed at endoscopy. Infiltration of neutrophils was observed in the TTW fluid cytology implying chronic obstructive pulmonary disease (COPD). Therefore, the systemic glucocorticoid therapy was to be given for 3 weeks with improved ventilation provided at the same time. The respiratory symptoms started to improve in 7 days of therapy and were fully resolved by when the therapy was terminated. The horse is clinically normal now and being monitored for development of any signs of chronic obstructive pulmonary disease.

This study aimed to determine the changes of awareness and preference of dental hygienists according to the experience of using a digital intraoral scanner through a convergence study. Data collected by an online survey for dental hygienists in Busan, Gyeongnam and Gyeongbuk were analyzed by SPSS 24.0 program. When dental hygienists had an experience of using a digital intraoral scanner, the awareness and preference of digital intraoral scanners were significantly higher. The experience of using a digital intraoral scanner showed a positive correlation with the clinical application experience of digital intraoral scanners; the clinical application experience of digital intraoral scanners, with the awareness of digital intraoral scanners; and the awareness of digital intraoral scanners, with the preference of digital intraoral scanners. In conclusion, the dental hygienist's experience in clinical application of digital intraoral scanners is expected to increase the awareness and preference, resulting in the improvement of dental hygienists' work ability. Therefore, it is believed that continuous education and learning about digital oral scanners are needed.

Purpose This study was planned to compare and evaluate the stability of implant using $Osstell^{TM}$ and Osstell $Mentor^{TM}$. Material and methods Artificial bone and RBM(resorbable blasting media) surface blasted implants(Osstem US II, SS II implants - diameter: 4mm, length: 13mm) were used. To measure the stability of installed implants, $Osstell^{TM}$ and Osstell $Mentor^{TM}$ were used. In the first experiment, five implants were installed in D1(external type implants) and D3(internal type implants). In the second experiment, 4 internal type implants were divided in two groups and installed in D1 artificial bone with different depth. In the third experiment, two external implants were installed in D1 and D3 artificial bone each and two internal implants were installed in D1 and D3 artificial bone. In all groups, their stability were measured by $Osstell^{TM}$ and Osstell $Mentor^{TM}$. Results In all groups, $Osstell^{TM}$ and Osstell $Mentor^{TM}$ both showed reliable measurement values. The value difference between $Osstell^{TM}$ and Osstell $Mentor^{TM}$ was observed but the difference was small and clinically acceptable. Conclusion These results suggest that the use of Osstell $Mentor^{TM}$ has clinical relevance in the assessment of implant stability.

기니픽과 New Zealand White Rabbit에서 PDT-Hepa에 대한 항원성 시험을 실시하였다. 1) Active Systemic Anaphylaxis (ASA), 2) Passive Systemic Anaphylaxis (PSA), 3) Passive Custaneous Anaphylaxis (PCA) 시험을 실시한 결과 ASA, PSA 실험에서 anaphylaxis와 관련된 어떠한 특이적인 임상증상도 나타나지 않아 PDT-Hepa는 기니픽과 토끼에서 항원성이 없는 것으로 보인다. 또한 PCA 실험에서 청색반점이 관찰되지 않은 것으로 보아 PDT-Hepa specific IgE는 생성되지 않는 것으로 판단된다.

Nasometer를 통해 얻은 비음치(nasalance score)는 객관적일 뿐만 아니라 훈련된 언어임상가가 청지각적으로 판단한 비음도와 상관관계가 높기 때문에, 공명장애 진단의 보조자료로 유용하다. 그러나 비음치는 자극어에 따라 다양한 수치를 보이므로 공명장애의 진단을 위해서는 타당하고 신비로운 자극어의 개발이 요구되고 있다 따라서 본 연구는 비음치에 영향을 미치는 주요한 음운 환경이 무엇인지 살펴보고, 무의미 1음절어와 유의미 문장 자극어 중 어떤 것이 더 신뢰로운지 알아보아, 비음치 측적을 위한 자극어 개발에 기초를 마련하고자 하였다.

EEG(electroencephalogram)는 주로 전문가의 판독에 따른 주관적 판단에 의존하여 임상에서 사용되어져 왔다. 그러나 비선형 동역학 분석을 이용한 해석학적인 정량화 연구가 진행 되어짐에 따라 특이 패턴을 이용한 환자의 질병진단 이외에도 정상인의 뇌 활동 및 인지기능 둥을 이해하기 위한 도구로써 그 활용범위가 넓어지고 있다. 본 논문에서는 정상인에게 다양한 자극을 준 후 측정한 EEG를 상관차원 분석법을 이용하여 다양한 자극에 대한 뇌파의 특징을 분석하였다. 그 결과 각 자극에 따른 뇌 활동도의 차이를 정량적으로 분석할 수 있었으며, 뇌 활동 부위와 자극과의 관계도 정량적으로 분석할 수 있었다.

To characterize the recent outbreaks of canine distemper (CD) in Korea, we carried out epidemiological investigations by clinical observations, serum neutralizing (SN) antibody titer determination and RT-PCR on the 315 dogs which were clinically suspected as canine distemper virus (CDV) infection. One hundred and sixty two of 315 dogs were infected with CDV. Breed or gender did not seem to have effects on the prevalence of CD. The major part of dogs were in young age from 6 weeks to 18 weeks of age, and were not vaccinated or incompletely vaccinated. Clinical signs of dogs with CD were multi systemic and extremely variable. Dogs died from CD had significantly more ocular signs and neurologic signs than those of dogs survived (p<0.05). The SN titers against CDV of 157 (96.9%) dogs were under 1:16, which is less than protective level. One possible explanation for recent outbreaks of CD in Korea might be low antibody titers against CDV because of vaccination failure. Therefore, to reduce the impact of virulent infection in the dog population, dogs should be vaccinated adequately and prophylactic measures should include isolation of young dogs from the dog population until vaccination can be expected to provide protection.

Objective : The purpose of the research is to investigate Korean occupational therapists' awareness of Evidence-Based Practice(EBP), basis of clinical decision making, barrier factors of EBP execution. Methods : Form December 2009 to March 2010, 500 questionnaires were sent out to clinical occupational therapists and 160 questionnaire which are returned by the therapists were analyzed through descriptive statistics. Results : There are more female respondents than male. More than 90% of them had less than 5 years experience. Most of respondents hadn't experienced education concerning EBP(76%), and the education is not periodically conducted(55%). Moreover, treatment was being tailored based on subjective judgement. On the other hand, the degree of recognition showed that the professionalism of occupational therapists can be improved through EBP(96%), and be helpful to make clinical decision(88%). Most of the therapists answered that guaranteeing enough time to search the basis of treatment(90%) and participating in the education course(92%) is needed to make EBP applicable. This result shows that while the application rate of EBP is low, the recognition rate of EBP is high, which means it is necessary to revitalize EBP education program. Conclusions : In order to provide quality service, education course and instructor training program is needed. We should also make a great effort to offer evidence-based education to occupational therapy students. Furthermore, EBP has to be carried out to improve the professionalism of occupational therapists, and the research about education program and its effect has to be executed.
