Objective: This study was conducted for the nationwide statistical survey of poison exposure to provide the rationale for establishing and developing the poison control center (PCC) in Korea. Design: Study group for Korea PCC in National Medical Center reviewed the medical literature on poison exposure of Korea from death reports of National Statistical Office (NSO), the toxic exposure statistics from the report of National Health Insurance Corporation (NHIC), and poison related data from 119 ambulance services (FD) for the purpose of obtaining the poison and its related data. We also conducted questionnaire from the expert who work in emergency medicine department at the designated 320 emergency medical centers in Korea for the preparedness and acknowledgement about necessity of PCC and their need for that. Results: We reviewed the reliable data from the death report of NSO, poison exposure data from NHIC, and running report from FD. Poisoning death occured at home ($36.7\%$) and hospital ($46.3\%$). Poisoning are more common in rural area than the city area. Patients were seen more frequently in the local clinics than in any hospital. The drugs ($45.7\%$) and pesticide ($18.1\%$) are common poison. Common place to poison exposure were residential area ($39.9\%$), industry ($9\%$). mass residential area ($7\%$). and farm ($6\%$). The education level were primary school ($33.2\%$), high school ($23.7\%$), and middle schol ($21.3\%$) in order. We have to provide the poison guideline for lay public to understand easily, and for medical experts. The medical facilities need to be invested and have more interest for toxicology. All medical staff who work in the designated emergency medical center want PCC to establish. They want to have poison information from hospital ($91.3\%$), regional poison information center ($45.0\%$), regional poison control center ($52.5\%$), nationwide poison information center ($48.8\%$), nationwide poison control center ($46.25\%$), as a role of poison control center. They also want that pcc have poison epidemiologic study and statstics, training program for the experts, registration of rare case of posion on website, reflection of policies to activities for antidote production etc., speedy consultation system for poison analysis, public education, establishment of both regional and national pee, etc. Conclusion: Poison center must be established to provide poison information for all the public and medical experitise, focusing rural area and private clinic, to detoxify, to reduce the cost, time, morbity, and mortality through the whole country.

A novel tracking method is proposed to find coronary artery using high-order curve model in coronary CTA(Computed Tomography Angiography). The proposed method quickly generates numerous artificial trajectories represented by high-order curves, and each trajectory has its own cost. The only high-ranked trajectories, located in the target structure, are selected depending on their costs, and then an optimal curve as the centerline will be found. After tracking, each optimal curve segment is connected, where optimal curve segments share the same point, to a single curve and it is a piecewise smooth curve. We demonstrated the high-order curve is a proper model for classification of coronary artery. The experimental results on public data set sho that the proposed method is comparable at both accuracy and running time to the state-of-the-art methods.
The purpose of this study is to contribute to developing psychological support system in disaster response of South Korea by examining that of Japan. Psychosocial support from the Red Cross with the psychiatric support by the DPAT from local government were achieved in the early stage of disaster psychology support system in Japan. In the long term intervention after disaster, psychiatric support from Kokoro-no care center has been established. In other words, not only traditional mental health approach but also disaster psychology support activities including psychosocial support are deployed. National Information Center of Disaster Mental Health, which is control tower of disaster psychology support, understand the disaster in the level of nationwide through collecting and analyzing the data related to disaster, and manage disaster psychological support activities. Disaster psychology support system in Japan modified problems immediately during large scale disaster that they are equipped with state of the current. Implications for disaster psychological support system and crisis counseling program in South Korea are discussed.

Objectives: Nanomaterials have been used in various fields. As use of nanoproducts is increasing, workers dealing with nanomaterials are also gradually increasing. Exposure assessments for nanomaterials have been carried out for protection of worker's health in workplace. Exposure studies were mainly focused on manufacturing processes, but these studies on after-treatment processes such as refinement, weighing, and packing were insufficient. So, we investigated exposure characteristics of particles during after-treatment processes of $Al_2O_3$ fibers and Ni powders. Methods: Mass-production of Ni powder process was carried out in enclosed capture-type canopy hood. In a developing stage, $Al_2O_3$ was handled with a local ventilation unit. Exposure characteristics of particles were investigated for $Al_2O_3$ fiber and Ni powder processes during the periods of 10:00 to 16:00, 20 May 2014 and 13:00 to 16:00, 21 May 2014, respectively. Three real-time aerosol instruments were utilized in exposure assessment. A scanning mobility particle sizer(SMPS, nanoscan, model 3910, TSI) and an optical particle counter(OPC, portable aerosol spectrometer, model 1.109, Grimm) were used to determine the particle size distribution in the size range of 10-420 nm and $0.25-32{\mu}m$, respectively. In addition, a nanoparticle aerosol monitor(NAM, model 9000, TSI) was used to measure lung-deposited nanoparticle surface area. Membrane filters(isopore membrane filter, pore size of 100 nm) were also used for air sampling for the FE-SEM(model S-5000H, Hitachi) analysis using a personal sampling pump(model GilAir Plus by 2.5 L/min, Gilian). Conclusions: For Ni powder after-treatment process, only 27% increase in particle concentration was found during the process. However, for $Al_2O_3$ fiber after-treatment process, significant exposure(1.56-3.34 times) was observed during the process.
Background: The European Centre for Ecotoxicology and Toxicology of Chemicals' Targeted Risk Assessment (ECETOC TRA) tool has been recognized by EU REACH as a preferred approach for calculating worker health risks from chemicals. Objectives: The applicability of the ECETOC TRA to occupational exposure estimation from industrial uses of methanol was studied by inputting surveyed and varied parameters for TRA estimation as well as through comparison with measured data. Methods: Information on uses of methanol was collected from seven working environment monitoring reports along with the measured exposure data. Input parameters for TRA estimation such as operating conditions (OCs), risk management measures (RMMs) and process categories (PROCs) were surveyed. To compare with measured exposures, parameters from the surveyed conditions of ventilation but no use of respiratory protection were applied. Results: PROCs 4, 5, 8a, 10, and 15 were assigned to ten uses of methanol. The uses include as a solvent for manufacturing sun cream, surfactants, dyestuffs, films and adhesives. Methanol was also used as a component in a release agent, hardening media and mold wash for cast products as well as a component of hard-coating solution and a viscosity-controlling agent for manufacturing glass lenses. PROC 8a and PROC 10 of a cast product manufacturer without LEV (local exhaust ventilation) and general ventilation as well as no respiratory protection resulted in the highest exposure to methanol. Assuming the identical worst OCs and RMMs for all uses, exposures from PROC 5, 8a, and 10 were the same and the highest followed by PROC 4 and 15. The estimation resulted in higher exposures in nine uses except one use where measured exposure approximated exposures without RMMs. Conclusions: The role of ECETOC TRA as a conservative exposure assessment tool was confirmed by comparison with measured data. Moreover, it can guide which RMMs should be applied for the safe use of methanol.
Purpose: This study aimed to explore the public attitude toward the development of national health program for cancer survivorship. Based on the results of this survey suggest the necessity of national health program for cancer survivorship. Methods: We surveyed 1,015 adults who were over 20 years of age from the sixteen cities and local districts of Korea. We conducted a telephone survey with a structured questionnaire on the post-treatment care at the nation and on the permission as the handicapped for cancer. Results: Fifty-six percent of respondents answered that post-treatment program at the national level is very necessary and twenty-seven percent replied that it is necessary. Respondents emphasized 'Expanding insurance coverage for post-treatment care' (29.8%) and 'Systematic education and rehabilitation programs after treatment' (25.6%). This study found that a lower educational level [adjusted odds ratio (aOR)=1.36; 95% confidence interval (CI)=1.04~1.77], earning under 300 per month [aOR=1.36; 95% CI=1.04~1.77], being married (60.2%) [aOR=1.79; 95% CI=1.34~2.37] and thought higher level of cancer treatment in Korea than the advanced (64.4%) [aOR=1.56; 95% CI=1.15~2.12] influenced the positive attitude toward a national health program. Sixty-eight percent of respondents answered 'Strongly agree' or 'agree' to permission for cancer survivors as the handicapped. People who have been married (72.4%) [aOR=1.89; 95% CI=1.41~2.53] and who have had a lower educational level [aOR=1.35; 95% CI=1.03~1.78] responded that they agree more to permission for cancer survivors as the handicapped. Conclusion: This study shows the positive public attitude of the public toward the national health program for the cancer survivors.

Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) contents in marine sediment and edible fish (4 species) from the estuary near the Yongho wharf in Busan were determined to assess their presence and their potential health risk to the local population through fish consumption was also assessed. Levels of ${\Sigma}PCBs$ and ${\Sigma}DDTs$ in marine sediment were 3.22~197.65 and 1.77~20.27 ng/g dw, respectively. HCHs and endosulfan sulfate concentrations in bottom sediment were 1.42~6.08, 0.56~13.89 ng/g dw, respectively. The bottom sediment in the offshore of the Yongho wharf may be characterized as semi-polluted status with potential adverse marine biological effects in terms of sediment quality guidelines of US NOAA. The mean concentrations of ${\Sigma}PCBs$ in the tissues of olive flounder (Paralichthys olivaceus), Korean rockfish (Sebastes schlegelii), file fish (Stephanolepis cirrhifer) and abbysal searobin (Lepidotrigla abyssalis) were 67.37, 10.20, 48.26, 22.81 ng/g lw, respectively. DDTs and HCHs were also detected in all fish samples. Lifetime cancer risk and target hazard quotient to local residents due to those fish consumption were found to pose negligible cancer and non-cancer risk.

Objective: To assess the health and economic burden of human papillomavirus (HPV)-related diseases (cervical cancer, cervical intraepithelial neoplasia (CIN) 1/2/3, and genital warts) in Singapore over a period of 25 years beginning in 2008. Methods: Incidence-based modeling was used to estimate the incidence cases and associated economic burden, with the assumption that age-stratified incidence rates will remain the same throughout the period of 25 years. The incidence rates in 2008 were projected based on data obtained from the National Cancer Registry for cervical cancer, and from a combination of published data and hospital registry review for CIN1/2/3 and genital warts. The population growth rate was factored into the projection of incidence cases over time. Direct cost data per cervical cancer and per CIN1/2/3 case were obtained from the financial database of large local hospitals while cost data for genital warts were obtained from the National Skin Center; these costs were multiplied by the number of incidence cases to produce an aggregate estimate of the economic burden over the 25-year period (in 2008 Singapore dollars) using a 3% discount rate. Results: The total number of incidence cases of HPV-disease over 25 years beginning in 2008 was estimated to be 60,183, including 8,078 for cervical cancer, 11,685 for CIN 2/3, 8,849 for CIN1, and 31,572 for genital warts. The estimated total direct cost was 83.2 million Singapore Dollars over 25 years: 57.6 million attributable to cervical cancer, 13.0 million to CIN2/3, 6.83 million to CIN1, and 5.70 million to genital warts. Conclusion: HPV-related diseases are expected to impose significant health and economic burden on the Singapore healthcare resources in the next 25 years.
Background: Breast cancer is the most common cancer of women and the principal cause of death in middle aged women. The objective of this study was to describe the trend of breast cancer and its management in Aden and adjacent south-eastern governorates of Yemen during the last 20 years. Patients and Methods: This is a retrospective analysis of previous studies on patients with breast cancer in Aden and adjacent south-eastern governorates, Yemen (January 1989 through December 2007). The studied variables were: sex, age, time and type of presentation, disease stage, pathological types and the performed surgical treatment. The sources of information were the treatment registry of Aden health office, archives of Al-Gamhouria teaching hospital; major referral and other public and private hospitals in Aden and Aden Cancer Registry. Results: The total number of patients was 476, 99% being females. The age range was 19-88 years. The most affected age was 30-50 years (60.5%), 95% presenting after one month of having breast symptoms. Forty-five percent presented with signs of advanced local disease, while 59.2% had palpable axillary lymph nodes on presentation. Early breast cancer (stages I-II) occurred in 47%, and late breast cancer (stages III-IV) in 51.5%. Invasive ductal carcinoma was the commonest pathology (89.3%). The main surgical treatment was mastectomy (modified radical mastectomy (50%). Conclusion: Breast cancer is predominantly a disease of young with late presentation and advanced disease. Improving health awareness and earlier diagnosis of the disease by health education, encouraging breast self-examination, and providing the mammography equipment and mammary clinics in hospitals are recommended. Establishment of oncology and radiotherapy centers in Aden is a necessity.
Purpose: 'The purpose of the present study was to understand students' experiences from their standpoint, to identify relevant variables and to examine into their relations by analyzing and describing what phenomenon 'nursing students' visiting ambulatory bathing service' is, what are the reasons for the phenomenon, and what interactions are in the phenomenon. Method: The subjects were thirteen students. Data were collected through in-depth interviews and analyzed by Strauss and Corbin's analysis method. Result: With regard to ambulatory bathing service, participants responded 'lack of education', 'inexperienced personal relations' and 'disappointment with recipients families'. They recognized 'burden' and 'compassion'. The intensity of generated 'burden' and 'compassion' was determined by volunteering persons, the degree of health care service, recipients' response and interaction of climate. When 'burden' and 'compassion' were generated, participants selected their own coping strategies. Strategies in the situation of 'burden' and 'compassion' were significantly influenced by 'burden' and 'compassion' and structural situation - 'mutual relation structure,' 'volunteers' capability,' 'the degree of volunteering guidance,' 'community participation,' 'recipients' environment,' 'information sharing,' 'special vehicle equipment' and 'economical burden.' Strategies include' service training,' 'receiving volunteering training,' 'preliminary service preparation,' 'volunteering.' 'connection to local medical center,' 'intention,' 'information sharing,' 'passive response to recipients' appreciation' and 'the understanding of publicity'. The results of selected 'burden' and 'compassion' are described with 'worthiness' and 'cohesion' as follows. Conclusion: This study is significantly meaningful in that it examined bathing service welfare in its initial stage. There are not much outcome from previous studies. However. it is meaningful that this study intended to develop theories on the nature of experiences and the relations among concepts derived from the visiting ambulatory bathing service process of nursing students. Professors who taught social volunteering in universities understood the experience of nursing students who did the visiting ambulatory bathing service. Consequently, professors will provide an effective instruction to enable these students to carry out visiting ambulatory bathing services efficiently in order to meet demands when they conduct the services. For the volunteering service activity in major-related fields among college students' social volunteering activities, they recognized the necessity of systematic education and preparation.
