생명 공학 분야에서는 노이즈가 많고 불완전한 데이터 집합의 사용이 많이 이루어진다. 불완전한 그래프에서 구조적 차이를 고려한 근사 서브 그래프 매칭에 대한 활용이 이루어지고 있다. 본 논문에서는 기존 기법에서 모든 데이터 및 경우의 수를 색인하는 과도한 색인 문제와 계산 비용 감소를 위한 요약 색인 기법을 제안한다. 구조적 차이 정보를 저장하기 위해서 특정 정점간의 최단 거리 값을 관리하고, 색인 부하 감소 및 일관성을 위해 요약 색인에 대한 간결화 작업을 수행한다.

As one of the Korean VLBI Network (KVN) Key Science Programs, the Interferometric Monitoring of Gamma-ray Bright AGNs (iMOGABA) aims to reveal the origins and nature of the gamma ray flares in active galactic nuclei (AGNi). Here we report a summary of activities and recent scientific results of the iMOGABA program, including statistical properties of the whole sample, as well as scientific highlights for the iMOGABA on specific sources. We also introduce future prospects and directions for the development and expansion of iMOGABA.

We review recent research related to shearing interferometry, reported over the last two decades. Shearing interferometry is categorized as azimuthal, radial, or lateral shearing interferometers by its fundamental principle to generate interference. In this review the research trends for each technique are provided, with a summary of experimental results containing theoretical background, the optical configuration, analysis, and perspective on its application fields.

Objective: The aim of this systematic review was to investigate for effective strategies to improve home exercise program (HEP) adherence in vestibular rehabilitation (VR). Design: Systematic review. Methods: A systematic review was conducted to identify effective strategies used to improve HEP adherence of patients in VR. Six databases, Academic Search Premier, Cochrane Library, CINAHL, PUBMED, PsycINFO, and Web of Science were searched from their inception to December 31, 2015. The keywords used for search were 'home program', 'home intervention', 'compliance', 'adherence', 'vestibular rehabilitation', 'motion sickness', and 'motion sensitivity'. Results: A total of eight studies were selected to be included in the review. There was 95.2% agreement between the two reviewers who reviewed the studies using a quality assessment tool. The overall inter-rater agreement (${\kappa}$=0.73) showed good agreement between the reviewers. Strong evidence was identified for 3 major categories of effective HEP adherence strategies, 1) providing patient with written summary of HEP; 2) asking patient to maintain a record of HEP and symptoms; and 3) providing tele-rehabilitation in form of email and/or telephone support along with in person treatment sessions. Also, based on strong evidence, computerized technology was not found to be superior to other strategies for improving patients' HEP adherence in VR. Conclusions: The effective strategies for improving HEP in VR include written summary of exercise, maintenance of log of HEP and symptoms and tele-rehabilitation along with in person treatment sessions.

Bevacizumab has been approved for use in combination with chemotherapy to treat many types of cancer but associated neutropenic events, including febrile neutropenia, have been reported. To estimate the incidence and relative risk of neutropenic events in cancer patients treated with bevacizumab combination therapy, we searched PubMed, EMBASE, and Web of Science literature databases, as well as abstracts presented at the American Society of Clinical Oncology conferences, to identify relevant studies published from January 1966 to December 2011. Studies that compared bevacizumab plus chemotherapy or biological therapy with chemotherapy or biological therapy alone, and that had adequate safety data profiles, were selected for analysis. Statistical analyses were conducted to calculate the summary incidence rates, relative risks (RRs), and 95% confidence intervals (CIs) using fixed- or random-effects models. A total of 22 clinical trials involving 15,056 patients were included in the analysis. The summary incidences of high-grade neutropenia (HGN) and high-grade febrile neutropenia (HGFN) in patients receiving bevacizumab was 27.3% (95% CI: 26.4%-28.3%) and 3.91% (95% CI: 3.51%-4.37%), respectively. The risks of HGN (RR=1.10; 95% CI: 1.02-1.19; P=0.02) and HGFN (RR=1.31; 95% CI: 1.08-1.59; P=0.005) were significantly increased in bevacizumab-treated patients, compared to those who did not receive bevacizumab. The RR of bevacizumab-associated HGN, but not HGFN, varied significantly with tumor types (P=0.005). The increased risk of bevacizumab-associated neutropenic events was dose-dependent, as the RR was greater at a dose of 5 mg/kg/week than at 2.5 mg/kg/week. Our findings suggest that bevacizumab addition to cancer therapy significantly increases the risk of serious neutropenic events, and this risk may be dose-dependent.

Purpose: The purpose of this cross-sectional study was to examine the relationship between characteristics of severe ALS patient-caregiver couples and health related quality of life (HRQoL) in family caregivers. Methods: The participants in this study were 89 pairs of ALS patients using ventilators and a family caregiver. The characteristics of the ALS patients and caregivers, Korean-Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised, Zarit Burden Interview and SF-36 were measured in this study. The data were collected from August 2008 to April 2009. Descriptive statistics, Pearson correlation coefficients, and canonical correlation were used for data analysis. Results: The physical component summary and mental component summary of the HRQoL score for family caregivers were $147.49{\pm}31.63$ and $129.09{\pm}35.83$, respectively. HRQoL for caregivers was related to characteristics of the ALS patient-caregiver couples, such as patient's gender, caregiver's age, gender, marital status, daily time spent in caregiving and burden with one significant canonical variable. The significant variate showed that the lower the age, the time spent in caregiving and the burden of caregivers, the higher the HRQoL of caregivers. Conclusion: The support systems for caregivers considering caregiver characteristics such as demographics and burden should be implemented to improve the HRQoL of caregivers.

Aim: We conducted a study in China to assess the health-related quality of life (HRQoL) in patients treated on for malignant bone tumors after surgery, and investigate the possible determinants. Methods: The subjects were 120 patients surgically treated by amputation and limb-salvage for bone tumors during the period of June 2008 to June 2010. The Medical Outcomes Study Short Form 36 (SF-36) was employed to measure the HRQoL of all the patients before and after surgery. Results: With regard to the results of the general quality of life tool (SF-36), we observed a significant improvement of all the indexes of HRQoL after 6 months (p<0.05). PF, RP and BP scores showed significant increase between surgery after 6 and 12 months (p<0.05). The means of the HRQoL of bone tumor patients in our study were still much lower than those of general population in every domain, even 12 months after surgery. Logistic regression showed that female patients were found to have lower scores in physical component summary (PCS) than males (OR=0.64, 95% CI=0.35-0.89). Patients older than 15 years had lower scores in mental component summary (MCS) (OR=0.60, 95% CI=0.32-0.86). Ablative surgery was related to both lower MCS and PCS scores (For MCS, OR=0.54, 95% CI=0.31-0.83; for PCS, OR=0.43, 95% CI=0.25-0.73). Conclusion: Our study showed the treatment for bone tumor could greatly alter the HRQoL of patients. Age, sex and type of surgery were associated with physical or mental HRQoL after surgery.
