최근 얼굴 인식 기술과 하드웨어의 빠른 발전으로 인해 실시간 얼굴 검출이 가능한 다양한 어플리케이션이 제시되고 있다. 특히 네트워크의 발달과 영상 장비의 저 비용화로 IP 기반의 네트워크 감시 카메라와 얼굴 검출 기술을 이용한 스마트 감시 카메라의 요구와 저장된 감시카메라의 영상에서 얼굴 검출을 할 수 있는 스마트 감시 시스템의 요구가 증대되고 있다. 그러나 대부분의 감시 시스템은 네트워크 대역폭과 저장 용량을 감소시키기 위하여 영상을 압축하고 있다. 압축된 영상을 전부 디코딩 하고 모든 프레임에서 얼굴 검출을 하는 것은 시스템 성능 요구사항을 증대시키므로 압축된 영상을 이용한 빠른 얼굴 검출기법이 요구되고 있다. 본 논문은 기존의 Haar like features와 adaboost 학습기 등의 고속화된 얼굴 검출 알고리즘과 모션정보를 이용한 프레임 저감기법을 이용하여 압축된 프레임에서 고속으로 얼굴검출을 하는 방법을 제시하고 방송 응용분야에 대해 논의 하고자 한다.

본 논문은 Java를 이용하여 Web환경에서 사용자들이 용이하게 항공기의 운항정보들을 획득할 수 있는 자동항행감시기능의 개발에 대한 것이다. 개발된 기능은 서버와 클라이언트 기능으로 구분된다. 서버는 GPS가 탑재된 항공기로부터 수신된 위치를 데이터베이스에 축척하는 기능과 클라이언트 브라우저로부터의 접속요구에 대하여 Java 애플릿을 송신하는 Web 서버기능을 동시에 가지고 있다. 따라서, 각 클라이언트들은 특정 소프트웨어 없이도 Java 애플릿만 전달받아, 서버의 운항정보 데이터베이스에 접근하여 운항정보를 화면에 실시간으로 현시할 수 있다. 이러한 기능은 기존 장비들이 단독 장치거나 특정 소프트웨어가 필요한 것에 비하여 큰 장점이 있으며, 소프트웨어의 기능향상시 서버측 기능만 수정하면 되므로, 유지보수면에서 또 다른 장점이 있다. Mooney항공기의 운항정보를 수집하여 시험해 본 결과, 본 시제품이 상용 제품개발시 기여할 수 있을 것임을 확인하였다.

안전과 보안상의 이유로 감시 카메라의 시장이 확대되고 있으며 이에 대해 영상 인식 및 추적에 관한 연구도 활발히 진행 중에 있으나 인식 및 추적되는 객체의 정보를 획득하여 객체를 식별하는 데는 한계가 있다. 특히, 감시카메라가 활용되는 쇼핑몰, 공항 등과 같은 개방된 공간에서는 다수의 객체들을 식별하기란 더욱 어렵다. 따라서 본 논문에서는 기존의 영상기반 객체 인식 및 추적 시스템에 RFID 기술을 더하여 객체 식별기능을 추가하고자 하였으며 영상 기반과 RFID의 문제 해결을 위해 상호 보완하고자 하였다. 그리하여 시스템의 모듈별 상호작용을 통해 영상기반 객체 인식 및 추적에 실패할 수 있는 문제와 RFID의 인식 오류로 발생할 수 있는 문제에 대한 해결 방안을 제시하였다. 객체의 식별 정도를 4단계로 분류하여 가장 최상의 단계로 객체가 식별이 되도록 시스템을 설계해 식별된 객체의 데이터 신뢰성을 유지할 수 있도록 하였다. 시스템의 효율성 판단을 위해 시뮬레이션 프로그램을 구현하여 이를 입증하였다.

Cancer registration, an important component of cancer surveillance, is essential to a unified, scientific and public health approach to cancer prevention and control. India has one of the highest cancer incidence and mortality rates in the world. A good surveillance system in the form of cancer registries is important for planning and evaluating cancer-control activities. Cancer registration in India was initiated in 1964 and expanded since 1982, through initiation of the National Cancer Registry Program (NCRP) by the Indian Council of Medical Research. NCRP currently has twenty-six population based registries and seven hospital based registries. Yet, Indian cancer registries, mostly in urban areas, cover less than 15% of the population. Other potential concerns about some Indian registries include accuracy and detail of information on cancer diagnosis, and timeliness in updating the registry databases. It is also important that necessary data collection related quality assurance measures be undertaken rigorously by the registries to ensure reliable and valid information availability. This paper reviews the current status of cancer registration in India and discusses some of the important pitfalls and issues related to cancer registration. Cancer registration in India should be complemented with a nationwide effort to foster systematic investigations of cancer patterns and trends by states, regions and sub populations and allow a continuous cycle of measurement, communication and action.

Objectives: The aim of this study was to determine the prevalence of asymptomatic carriers of group A ${\beta}-hemolytic$ streptococci (GAS) in children living in a rural community and to investigate the association between episodes of acute pharyngitis and carrier status. Methods: Throat swabs were collected from September to November 2013 among children 5-13 years of age from a rural community (Maria Ignacia-Vela, Argentina). The phenotypic characterization of isolates was performed by conventional tests. Antimicrobial susceptibility was assayed for penicillin, tetracycline, chloramphenicol, erythromycin, and clindamycin (disk diffusion). The minimum inhibitory concentration was determined for penicillin, cefotaxime, tetracycline, and erythromycin. Results: The carriage of ${\beta}-hemolytic$ streptococci was detected in 18.1% of participants, with Streptococcus pyogenes in 18 participants followed by S. dysgalactiae ssp. equisimilis in 5. The highest proportion of GAS was found in 8 to 10-year-old children. No significant association between the number of episodes of acute pharyngitis suffered in the last year and the carrier state was detected (p>0.05). Tetracycline resistance (55.5%) and macrolide-resistant phenotypes (11.1%) were observed. Resistance to penicillin, cefotaxime, or chloramphenicol was not expressed in any streptococcal isolate. Conclusions: The present study demonstrated significant throat carriage of GAS and the presence of group C streptococci (S. dysgalactiae ssp. equisimilis) in an Argentinian rural population. These results point out the need for continuous surveillance of GAS and non-GAS carriage as well as of antimicrobial resistance in highly susceptible populations, such as school-aged rural children. An extended surveillance program including school-aged children from different cities should be considered to estimate the prevalence of GAS carriage in Argentina.

Phenylketonuria is a disease caused by congenital defects in phenylalanine metabolism that leads to irreversible nerve cell damage. However, its detection in the early days of life can reduce its severity. Thus, many countries have started disease screening programs for neonates. The present study aimed to determine the worldwide prevalence of classic phenylketonuria using the data of neonatal screening studies.The PubMed, Web of Sciences, Sciences Direct, ProQuest, and Scopus databases were searched for related articles. Article quality was evaluated using the Joanna Briggs Institute Critical Appraisal Evaluation Checklist. A random effect was used to calculate the pooled prevalence, and a phenylketonuria prevalence per 100,000 neonates was reported. A total of 53 studies with 119,152,905 participants conducted in 1964-2017 were included in this systematic review. The highest prevalence (38.13) was reported in Turkey, while the lowest (0.3) in Thailand. A total of 46 studies were entered into the meta-analysis for pooled prevalence estimation. The overall worldwide prevalence of the disease is 6.002 per 100,000 neonates (95% confidence interval, 5.07-6.93). The meta-regression test showed high heterogeneity in the worldwide disease prevalence (I²=99%). Heterogeneity in the worldwide prevalence of phenylketonuria is high, possibly due to differences in factors affecting the disease, such as consanguineous marriages and genetic reserves in different countries, study performance, diagnostic tests, cutoff points, and sample size.

Objectives: This study provides insights on the impact of a targeted intervention (TI) programme on behaviour change among injecting drug users (IDUs) in India. Methods: This paper examined the data from the Integrated Biological and Behavioural Surveillance 2014-2015 for IDUs in India. Logistic regression was performed to understand the factors (TI programme services) that affected injecting risk behaviours by adjusting for covariates. Propensity score matching was conducted to understand the impact of the TI programme on using new needles/syringes and sharing needles/syringes in the most recent injecting episode by accounting for the covariates that predicted receiving the intervention. Results: Participants who received new needles and syringes from peer educators or outreach workers were 1.3 times (adjusted odds ratio, 1.29; 95% confidence interval [CI], 1.09 to 1.53) more likely to use new needles/syringes during most recent injecting episode than participants who did not receive needles/syringes. The matched-samples estimate (i.e., average treatment effect on treated) of using new needles in the most recent injecting episode showed a 2.8% (95% CI, 0.0 to 5.6) increase in the use of new needles and a 6.5% (95% CI, -9.7 to -3.3) decrease in needle sharing in the most recent injecting episode in participants who received new needles/syringes. There was a 2.2% (95% CI, -3.8 to -0.6) decrease in needle sharing in the most recent injecting episode among participants who were referred to other services (integrated counselling and testing centre, detox centres, etc.). Conclusions: The TI programme proved to be effective for behaviour change among IDUs, as substantiated by the use of new needles/syringes and sharing of needles/syringes.

The objectives of this study are (i) to review current situations and problems of the occupational health care system with emphasis on reforming the organizations and services, (ii) to find out a disirable occupational health system model based on integration of the occupational health system and the general health system, and finally, (iii) to suggest policy implications in occupational health services in the light of objectives of the newly emerging national health insurance reform in Korea. The major policy implications of this study are as follows: 1. In the long-run, within the occupational health system, preventive occupational health services such as employees' physical check-up, working environment examination, etc should financially be integrated with industrial accident compensation insurance. Currently separately paying expenses for each different category of services by the owner of an enterprise should be disbursed once through the payment of contributions of industrial accident compensation insurance. And then, it is necessary to strengthen and expand the role and function of industrial accident compensation insurance to cover preventive occupational health services. 2. The occupational health system should be integrated with general health system for its effective management. For the short-term policy, it is necessary to eliminate fiscal and access barrier between industrial accident compensation insurance and national health insurance by means of ex post facto settlement of accounts. The duplication of employees' physical check- ups between under the health insurance program and under the industrial health services must be coordinated in a manner either through mutual authorization by the two parties concerned or through merge into the health insurance. 3. The intent of current employees' physical check-up system focused on detection of occupational diseases, should be converted to an idea of medical surveillance system or biological moritoring system. The introduction of medical surveillance or biological monitoring system is a necessary condition to build a positive, effective and inexpensive occupational health care system.
