Background: The aim of this study was to describe the clinical and microbiological characteristics of infective arthritis and to analyze risk factors for Gram-negative bacterial infections that cause infective arthritis. Materials and Methods: Patients admitted between 2009 - 2018 with infective arthritis in a single-tertiary hospital were evaluated retrospectively. Results: A total of 181 patients were enrolled in this study. Of them, 135 were native joint infection patients and 46 were prosthetic joint infection patients. The most common site of infective arthritis was the knee (63.6%), followed by the shoulder (17.7%), and the hip (9.9%). The most frequently identified microorganisms were Staphylococcus aureus (51.1%), followed by Streptococci sp. (21.1%), Enterobacteriaceae (8.4%), and coagulase-negative-Staphylococci (CNS; 8.4%). Infections due to Gram-negative bacteria and fungi made up 13.7% and 3.2% of all cases, respectively. Additionally, 20% and 4.2% of the cases involved methicillin-resistant S. aureus (MRSA) and MRCNS. We found that bacteriuria, infective arthritis in the hip, and steroid use at admission are independent risk factors for Gram-negative bacterial infections. Conclusion: Infective arthritis with methicillin-resistant microorganisms reached up to about 25% in a single-tertiary hospital in Korea. In case of suspected urinary tract infection, infective arthritis of the hip joint, or steroid use at admission time among infective arthritis patients, empirical treatment covering Gram-negative microorganisms can be considered.

본 연구는 위기청소년의 스마트폰 중독문제를 해결하기 위해 청소년 쉼터를 이용하거나 거주 중인 위기청소년의 사회적 요인과 스마트폰 중독과의 관계에서 자아효능감이 가지는 조절효과를 검증하고자 하였다. 연구대상자는 경기도에 소재하고 있는 쉼터(임시, 단기, 장기)에 보호하고 있는 위기청소년 211명을 대상으로 하였다. 연구의 필요성을 설명하고 2018년 9월 17일부터 09월 27일까지 조사를 실시하였다. 수집된 자료 분석은 SPSS 23.0 통계 프로그램을 활용하여 상관관계분석, 위계적 회귀분석을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 청소년 ?Y터를 이용하는 위기청소년의 스마트폰 중독에 친구들의 역할이 중요하다는 것이다. 사회적 관계를 형성하는 민감한 시기에 친구들의 지지는 중독에 빠지지 않게 하고 유익한 학창생활을 할 가능성을 높여 준다는 것이다. 둘째, 위기청소년의 자기효능감은 위기청소년들의 스마트폰 중독 해소에 도움을 줄 수 있을 것이다. The purpose of this study was to examine the moderating effect of self-efficacy in the relationship between the social factors of adolescent crisis youth and mobile phone addiction, using a youth shelter to solve the mobile phone addiction problem of crisis youth. The subjects of the study were 211 crisis youths who are protected in shelter (temporary, short-term, and long-term) located in Gyeonggi-do. The necessity of the study was explained and the survey was conducted from September 17 to September 27, 2018. To analyze the collected data, correlation analysis and hierarchical regression analysis were performed using SPSS 23.0 statistical program. The results of this study are summarized as follows. First, the role of friends is important in the mobile phone addiction of adolescents who use youth centers. The support of friends at a sensitive time to form social relations is that it does not lead to addiction and increases the likelihood of a beneficial school life. Second, the self-efficacy of the crisis youth could help the crisis youth to eliminate the mobile phone addiction.

In general, ophthalmologists visually grade the state of a patient by counting the cells within the anterior chamber OCT image. The manual cell counting method is highly inaccurate and spends a lot of time to determine the progress of the patient. In this work, we develop a new tool to count cells in anterior chamber OCT images to aid doctors in analyzing the state of patients. We exploit image processing to remove noises from images, segment the anterior chamber, and quantize the cells in OCT images. We also provide statistics to aid the doctors in determining the progress of the patients.
