Following the Anthrax bioterrorism attacks in the US in 2001, the Korean government established comprehensive countermeasures against bioterrorism. These measures included the government assuming management of all infectious agents that cause diseases, including smallpox, anthrax, plaque, botulism, and the causative agents of viral hemorrhagic fevers (ebola fever, marburg fever, and lassa fever) for national security. In addition, the Korean government is reinforcing the ability to prepare and respond to bioterrorism. Some of the measures being implemented include revising the laws and guidelines that apply to the use of infectious agents, the construction and operation of dual surveillance systems for bioterrorism, stockpiling and managing products necessary to respond to an emergency (smallpox vaccine, antibiotics, etc.) and vigorously training emergency room staff and heath workers to ensure they can respond appropriately. In addition, the government's measures include improved public relations, building and maintaining international cooperation, and developing new vaccines and drugs for treatments of infectious agents used to create bioweapons.

This study investigates the impact of precautionary measures, such as isolating exposed individuals, wearing masks, and maintaining physical distance, on preventing infectious disease. A deterministic SEIQHRV epidemic model is employed for this purpose. The model's positivity, boundedness, disease-free, and endemic equilibrium points are identified. A sensitivity test assesses the impact of preventive measures on infected classes. Results show that a basic reproduction number less than unity drives disease eradiction, while a higher unity value encourages the adoption of preventive measures.

본 연구는 3년간 버섯파리 발생소장 조사를 통해 발생 양상을 파악하였고 버섯파리 발생 최성기 이전에 물리적 방제기술을 적용하여 방제효과를 알아보았다. 버섯파리 사전방제를 위한 물리적 방제방법으로 재배사 출입구에 에어커튼을 설치하고, 출입구 주변으로 포충기와 끈끈이 트랩을 설치하여 버섯파리의 외부유입 차단과 내부 밀도 감소가 되게 하였고, 유기농업자재인 달마시안제충국 추출물을 주 1회 연무하여 화학적 방제기술을 병행처리 하였다. 또한 버섯파리 방제효과 조사를 위해 양송이 재배사 균상에 황색 끈끈이트랩(15×25 cm)을 3개 지점에 설치하여 사전방제기술 처리구와 무처리구의 버섯파리 발생 양상을 비교하였다. 관행대비 버섯파리 사전방제기술 적용 결과 버섯파리 발생 수준이 5월에는 15에서 6으로 약 60% 감소하였고, 6월에는 10에서 6으로 약 40% 감소함을 확인할 수 있었다. 종합적으로 버섯파리 급증시기에 사전방제기술 적용시 50% 이상의 방제효과를 얻을 수 있었지만, 외부 유입원 차단(재배사 문틈), 재배사 주변 청결관리(폐배지 재배사 옆 보관) 등 위의 결과를 보완하여 버섯파리 사전방제기술의 적용효과를 분석하고 응애 및 병원균과의 상관관계 분석 등 안전성 연구를 수행하여 양송이 안전생산 및 안정생산 기술이 농가에 보급될 수 있도록 추후 면밀한 연구가 진행되어야 할 것으로 판단된다.

This paper investigates a mathematical model of a system composed of two non-identical unit parallel system with common-cause failure, critical human error, non-critical human error, preventive maintenance and two type of repair, i.e. cheaper and costlier. This system goes for preventive maintenance at random epochs. We assume that the failure, repair and maintenance times are independent random variables. The failure rates, repair rates and preventive maintenance rate are constant for each unit. The system is analyzed by using the graphical evaluation and review technique (GERT) to obtain various related measures and we study the effect of the preventive maintenance preventive maintenance on the system performance. Certain important results have been derived as special cases. The plots for the mean time to system failure and the steady-state availability A(${\infty}$) of the system are drawn for different parametric values.

The detection of carious lesions is a key point to apply appropriate preventive measures or operative treatment of dental caries. A laser fluorescence device DIAGNOdent$^{(R)}$ (KaVo, Biberach, Germany) has also been shown to be of additional clinical value in the detection of initial caries. This report focus on the DIAGNOdent$^{(R)}$ for caries detection. DIAGNOdent$^{(R)}$ irradiate visible red light at a wavelength of 655 nm to elicit near-infrared fluorescence from caries lesion. This device is known as a reproducible method for caries detection, with good sensitivity and specificity especially for caries detection on occlusal and accessible smooth surfaces. DIAGNOdent$^{(R)}$ tended to be more sensitive method of detecting occlusal dentinal caries, however, showed more false-positive diagnoses than the visual inspection. So Clinician should not use the device as a clinician's primary diagnostic method and it is recommended that the device should be used in the decision-making process in relation to the diagnosis of caries as a second opinion in cases of doubt after visual inspection. The trend of modern dentistry would be a preventive approach rather than invasive treatment of the disease. This is possible only with early detection and respective preventive measures, DIAGNOdent$^{(R)}$ can help the changes.

Purpose: This report intend to provide basic materials of Musculoskeletal diseases prevention program development and preventive measures establishing by surveying Musculoskeletal symptoms. Musculoskeletal disease and Musculoskeletal disease prevention act about dental technician in Daegu. Methods: From October. 2012 to November. 2012 by conducting self - survey using questionnaire and use unit490 final analysis data. Results: In dental Technicians, as the musculoskeletal symptoms back or waist pain rate appear such as 28.2% and as the musculoskeletal disorders, the shoulder region pain complaint rate appear highly such as 87.4%. Musculoskeletal disease prevention act was highly appeared man more than women, the married than the unmarried, over 10 years dental experience, fewer working hours per day, the average monthly income is greater regular medical check-up dental technician than technician who do not. As working environment, In case working in laboratory whch dust is well ventilated and with a barrier, Musculoskeletal disease prevention act rate was highly appeared more than another technician who do not. Conclusion: We must prepare an effective preventive measures. To development Musculoskeletal disease prevention program suitable for dental technic working and make obliged to practice.

Objective: This study aims to provide empirical data on epidemic management measures and childcare teacher education in centers. It examines the relationship between infectious disease knowledge, health control knowledge, and self-efficacy in relation to the practice of preventive behaviors among infant and toddler teachers during the COVID-19 pandemic. Methods: The study involved 300 teachers from Seoul and Gyeonggi Province. Data were collected through questionnaires and analyzed using SPSS 23.0. Results: The study found that there is a positive relationship between childcare teachers' knowledge of infectious diseases and their engagement in preventive behavior. Additionally, internal control among the health care factors of childcare teachers also showed a positive relationship. Furthermore, the study revealed that the self-efficacy of childcare teachers is positively associated with their practice of preventive behavior. Overall, infectious disease knowledge, internal control measures, and self-efficacy were all found to have positive relationships with preventive behavior. Conclusion/Implications: This study proposes a new direction for future teacher education by highlighting the effectiveness of psychological factors, specifically health control materials and self-efficacy, in addition to focusing on improving infectious disease knowledge.

유선전화로 시작된 피싱 사기는 스미싱, 파밍 등으로 계속 진화하고 있다. 우리가 유 무선 통화, 문자, 이메일, 온라인 뱅킹 등을 편리하게 이용하고 있는 만큼 그에 따라 해킹 및 피싱 사기 공격의 종류도 진화하고 다양해지고 있는 것이다. 본 논문에서는 그에 따라 피싱의 종류에 따른 공격방법을 살펴보고 그에 따른 일반적인 예방대책을 살펴본다. 그리고 사용자들이 직접적으로 느낄 수 있는 실질적인 예방대책과 정부에서 추진할 수 있는, 장기적인 대책을 제시하였다. 계속 진화하는 피싱 사기를 단기간 내에 박멸하기는 어려우며 정부의 장 단기적인 대책과 기술개발 그리고 지속적인 홍보 등이 해결책이 될 것이다. 물론 SNS를 비롯한 인터넷상의 매체들도 홍보에 큰 도움이 되고 있다. 아울러 새로 개발되는 서비스기술들은 보안상의 허점이 없도록 다시 한번 살펴서 기술개발이 이루어져야 할 것이다.
