Jejudo has unique geographical and climatologic characteristics compared with other areas in Korea. The aim was to evaluate differences of the nationwide notifiable infectious diseases (NND) occurred in Jejudo, 2011~2018. The source of data was on the Infectious Disease Statistics System operated by Centers for Diseases Control & Prevention in Korea between 1 January 2001 and 30 September 2018. After calculating the proportion of sum of years showing a higher incidence in Jejudo than nationwide divided by sum of comparing years(PSYH), authors defined the infectious diseases for control in Jejudo (IDCJ) with PSYH over 75%. In addition, the infectious diseases showing increasing trends during recent 2 years(2015~2018) were defined as sudden increase Infectious diseases for control (SIDCJ). IDCJ in 2001~2018 included 3 NNDs such as chicken pox, syphilis, and Streptococcus pneumoniae. The results support main evidences to plan strategies and distribute community resources for control and prevention of NNDs in Jejudo, Korea.

Objectives: This study was carried out to estimate the magnitude of skin disease related to occupation and to find out the characteristics of it. Methods: We collected and analyzed the cases of occupational skin disease reported by surveillance system composed of doctors and nurses in 150 enterprises with dispensary or attacked hospital and physicians in 92 specific health examination institutes and 150 dermatologists from May to November, 1998. Results: Among members of surveillance system, 66 enterprises and 47 specific health examination institutes and 55 dermatologists reported 571 cases of occupational skin disease in 512 workers. Excepting 81 cases reported by dermatologists, We analyzed 490 cases reported by enterprises and specific health examination institutes. Among 490 cases, contact dermatitis was most common(368 cases, 75.1%) and the second was hyper or hypopigmentation(36 cases, 7.3%). When we analyzed the characteristics of workers with occupational contact dermatitis, male workers were 281 (79.2%) and female were 74(20.8%). 165 workers(64.5%) had chronic skin disease with repeated cure and relapse. 245 workers(72.5%) answered positively that their coworkers had similar skin disease. 27 workers(8.7%) experienced absence due to contact dermatitis related to occupation. To analyze the type of industries of workers with occupational contact dermatitis, automobile and trailer manufacturing industry was most common(105 cases, 29.6%) and the second was manufacturing industry for image, sound and communication equipment(55 cases, 15.5%). Organic solvent(183 cases, 46.7%) was the most common treating material of workers with contact dermatitis and the second was various kinds of chemicals(59cases, 15.1%). Conclusions: This is the first study using nationwide surveillance system to collect data of occupational skin disease. We found that many workers had skin disease related to occupation and characteristics of occupational skin disease were chronic and clustering. Therefore, we had to establish counterplan to manage occupational skin disease and to operate surveillance system to identify trends of occupational skin disease, continuously.

Senecavirus A (SVA), previously known as Seneca Valley virus, can cause vesicular disease and neonatal losses in pigs that is clinically indistinguishable from foot-and-mouth disease virus (FMDV). After the first case report in Canada in 2007, it had been restrictively identified in North America including United States. But, since 2015, SVA emerged outside North America in Brazil, and also in several the Asian countries including China, Thailand, and Vietnam. Considering the SVA occurrence in neighboring countries, there has been a high risk that Korea can be introduced at any time. In particular, it is very important in terms of differential diagnosis in the suspected case of vesicular diseases in countries where FMD is occurring. So far, several different molecular detection methods for SVV have been published but not validated as the reference method, yet. In this study, seven different molecular methods for detecting SVA were evaluated. Among them, the method by Flowler et al, (2017) targeted to 3D gene region with the highest sensitivity and no cross reaction with other vesicular disease agents including FMDV, VSV and SVD, was selected and applied further to antigen surveillance of SVA. A total of 245 samples of 157 pigs from 61 farms submitted for animal disease diagnose nationwide during 2018 were tested all negative. In 2018, no sign of SVA occurrence have been confirmed in Korea, but the results of the surveillance for SVA needs to be continued and accumulated at a high risk of SVA in neighboring countries.

Purpose: Total colonoscopy is recommended if colorectal polyps are clinically suspected. This study aimed to investigate the performance status of pediatric colonoscopic polypectomy in Korea. Methods: We surveyed pediatric endoscopic specialists who perform colonoscopic polypectomy in Korea using a questionnaire of 13 questions on pediatric colonoscopic polypectomy performance status. Results: The survey was conducted at 45 institutions, and 32 specialists (71.1%) responded. Among the respondents, 31.2% (10/32) said colonoscopy was performed in all age groups, while 12.5% (4/32) said sigmoidoscopy was performed in all age groups. Meanwhile, 56.2% (18/32) said that sigmoidoscopy was performed in young children, while colonoscopy was performed in older children. Among them, 38.9% (7/18) believe that 4-6 years were young, and 44.5% (8/18) believe that 7-9 years were young. Regarding surveillance examinations, 21.9% (7/32) said they would perform a surveillance colonoscopy or sigmoidoscopy in the future if less than five juvenile polyps were found in the colon. Meanwhile, if less than five adenomatous polyps were found in the colon, 93.8% (30/32) said they would perform surveillance colonoscopy or sigmoidoscopy in the future. Conclusion: More than half of the pediatric endoscopic specialists in Korea choose between a colonoscopy and sigmoidoscopy depending on the patient's age, contrary to the generally accepted recommendation of total colonoscopy if colorectal polyps are suspected in children and adolescents. In this survey, most pediatric endoscopists used the age range of 4-9 years as the reference age.

Objectives : We attempted to assess He accuracy of ICD codes for cerebrovascular diseases in medical insurance claims (ICMIC) and to investigate the reasons for error. This study was designed as a preliminary study to establish a nationwide surveillance system. Methods : A total of 626 patients with medical insurance claims who indicated a diagnosis of cerebrovascular diseases during the period from 1993 to 1997 was selected from the Korea Medical Insurance Corporation cohort (KMIC cohort: 115,600 persons). The KMIC cohort was 10% of those insured who had taken health examinations in 1990 and 1992 consecutively. The registered medical record administrators were trained in the survey technique and gathered data from March to May 1999. The definition of cerebrovascular diseases in this study included cases which met ore of two criteria (Minnesota, WHO) or 'definite stroke' in CT/MRI finding. We questioned the medical record administrators to explain the error if the final diagnoses were not coded as stroke. Results : The accuracy rate of the ICMIC was 83.0% (425 cases) Medical records were not available for 8.2% (51 cases) due to the closing of hospitals, the absence of a computer system or omission of medical record, etc. Sixty-three cases (10.0%) were classified as impossible to interpret due to insufficient records in 'major clinical symptoms' or 'neurological deficits'. The most common reason was 'to meet review criteria of medical insurance benefits (52.9%)'. The department where errors in the ICMIC occurred most frequently was the department for medical insurance claims in the hospital. Conclusion : The accuracy rate of the ICMIC was 83.0%.

본 연구는 국가 주요에너지 시설에 대한 보안진단결과를 분석하여 국가주요 에너지 시설의 보안향상방안을 제안하고자 한다. 대부분의 대상시설은 보안인력, 보안시스템, 울타리, 초소 등에 대한 외형적 보안요소는 적절하게 구축되어 있으나 이러한 보안요소 운용에 대한 인식수준 및 효율성은 낮은 것으로 분석되었다. 보안인력 수요산출의 불균형, 보안시스템 운용에 대한 기본지식 부족, CCTV 운용에 있어 과도한 Pan/Tilt/Zoom 기능 적용으로 인한 사각감시지역 발생, 카메라 위치의 부적절, 모니터 감시효율 저하, 그리고 자체 방호능력과 무관하게 작성된 보안계획서 등 미흡한 점이 있는 것으로 나타났다. 이러한 문제점을 보완하기 위해서 보안관리자의 전문성 제고가 우선되어야 하며, 선발 시 전문성 고려가 없기 때문에 보안관리자를 위한 전문 교육과정 신설이 필요하다. 그리고 보안업무 표준화를 통해 방호업무의 일관성을 유지하고 자체적인 보안진단의 기본 도구로 활용함으로써 보안수준을 향상시킬 수 있을 것으로 보인다.

In March 2003, classical swine fever (CSF) infection was reported in a piggery located at Iksan city, Jeollabuk-do in Korea. Subsequently, a total of 72 infected farms were confirmed between March and December, 2003. Based on epidemiological investigation of the earlier confirmed infected farms, the source of infection was shown to be from a breeding farm. Targeted surveillance of 82 piggeries that had acquired pigs from this breeding farm showed 44 piggeries were infected with CSF virus. CSF virus was introduced into this breeding farm by movement of selected breeder pigs from its 12 contracted farms which were located in areas that had been affected by CSF epidemic in late 2002. CSF had then spread through out the country mainly by direct transmission through the sale and movement of pigs from this breeding farm. Consequently, 47 (62%) among 72 CSF affected farms were associated, directly and indirectly, with this breeding farm. This study showed that inadequate control for breeding farms and transport restriction in CSF outbreak areas resulted in the nationwide spread of CSF and the failure of the eradication campaign that has been underway for several years by the Korean animal hygiene authority as well as the fanners. Improvements of control policy through further research of the 2003 CSF epidemic will be needed to reestablish the Korean CSF eradication program in the future.

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.

Background: The survival of hepatocellular carcinoma (HCC) patients is usually low due to late diagnosis. Cipto Mangunkusumo Hospital as the largest tertiary referral hospital in Indonesia, has recently improved its modalities for advanced HCC management, but there has not been any evaluation on any improvement in HCC patient survival. Materials and Methods: A retrospective analysis on 114 HCC patients in 2013-2014 were conducted and compared with the database for 77 HCC patients in 1998-1999. Clinical characteristics and treatment received were recorded and the survival of both groups was analyzed using the Kaplan-Meier method and compared using the log-rank test. Results: The percentage of HBV positive patients had increased after fifteen years from 32.5% to 67.5%. Only two patients (1.8%) in 2013-2014 were diagnosed with HCC during surveillance program. Proportions of Barcelona Clinic Liver Cancer A, B, C, and D in 2013-2014 were 1.8%, 42%, 28.1%, and 28.1%, respectively. There was an increase in the use of potentially curative treatment, such as surgical resection or combination of loco-regional therapies. The one-year survival rate increased from 24.1% in 1998-1999 to 29.4% in 2013-2014, while the median survival decreased from 146 days to 138 days, but the difference was not statistically significant (p=0.913). Conclusions: There was no improvement in the median survival of HCC patients after fifteen years because most continued to present at late stages. There is an urgent need for a nationwide implementation of a hepatitis screening program and HCC surveillance education.

A total of 3,943 samples (beef 698, pork 2,178 and chicken 1,067)were collected from slaughter houses in Daegu from January to December 2006 for analysis of antimicrobial residues. The results were also comparatively analyzed with those carried out from 16 veterinary service laboratories nationwide as a part of national residue program in 2006. The samples from 11 farms (cattle 2, pig 9) were found to exceed the legal limit. Among them 5 were classified as tetracyclines, 3 as $\beta$-lactams, 2 as sulfonamides and 1 as quinolone. Nationally a total of 222 farms (241 cases) were found to violate the residual limits, of which 47.3% were detected by screening test, followed by surveillance (38.3%). Failure to observe withholding periods of antimicrobial drugs after treatment was the most significant cause of the non-compliance.
