본 연구는 중학생의 안전실천과 인지실패의 정도를 알아보고, 이 들이 안전사고에 미치는 영향을 알아보기 위한 것이다. 연구대상자는 총 292명이며 2012년 11월 5일부터 11월 25일까지 설문조사하여 자료를 수집하였다. 연구도구는 SPSS win17.0을 사용하였고, 평균과 표준편차, Paired t-test, 피어슨 상관계수를 이용하였다. 대상자의 안전실천과 인지실패는 부(-)의 상관을 나타냈으며 안전에 대한 실천정도가 높은 대상자가 사고인지 실패율이 낮았다. 또한 안전사고 경험이 적게 나타났다. 그와 반대로 안전에 대한 인지실패가 높은 대상자는 안전사고 경험이 높게 나타났다. 따라서 안전실천과 인지실패의 정도를 지속적으로 파악하여 안전사고 예방에 대한 방안을 마련하기 위한 연구가 필요하다. 또한 연구의 범위를 확대함으로써 학교현장에 다양한 안전사고 예방 교육프로그램을 적용하여 안전의식 함양과 안전실천의 일반화가 이루어져야 한다.

Purpose: This study investigates human error accidents in the Korean railway sector, emphasizing the need for systematic management to prevent such incidents, which can have fatal consequences, especially in driving-related jobs. Research design, data and methodology: This paper analyzed data from the Aviation and Railway Accident Investigation Board and the Korea Transportation Safety Authority, examining 240 human error accidents that occurred over the last five years (2018-2022). The analysis focused on accidents in the driving, facility, electric, and control fields. Results: The findings indicate that the majority of human error accidents stem from negligence in confirmation checks, issues with work methods, and oversight in facility maintenance. In the driving field, errors such as signal check neglect and braking failures are prevalent, while in the facility and electric fields, the main issues are maintenance delays and neglect of safety measures. Conclusions: The paper concludes that human error accidents are complex and multifaceted, often resulting from a high workload on engineers and systemic issues within the railway system. Future research should delve into the causal relationships of these accidents and develop targeted prevention strategies through improved work processes, education, and training.

현대의 정보통신 기술과 네트워크 기술이 발달은 기업의 운영환경을 스마트하게 변화시켰으며, 그 가운데서 수많은 데이터들이 생성되고 저장되고 사용되고 있다. 기업경영의 에너지원이 되는 중요한 정보는 경제적인 이윤과 가치를 생성하고 또한 강력한 영향력의 근거로 활용된다. 따라서 주요정보는 그 가용성과 편의성을 확보해야 함과 동시에 기밀성과 무결성을 담보해야 하는 것이며 이것이 바로 정보보호의 기본목표가 된다고 할 수 있다. 그러나 대부분의 기업들은 중요한 내부정보가 유출되어 심각한 피해를 야기하는 사고가 증가하고 있다. 이에 본 연구에서는 내부정보유출을 방지하고 안정적인 데이터보안 및 정보보호관리 구축을 위한 DLP(Data Loss Prevention) 기술과 솔루션에 대해 살펴본다.

To prevent the incidence of type food allergies, removal of food allergens by excluding all foodstuffs containing the allergen(s) or disruption of allergen(s) using proteases has been employed. Though allergen- specific digestion with a protease worked well in the preparation of low allergenic goods, it is often difficult to destroy allergenicity without adversely affecting the nutritive value, taste and rheological properties of foods. In the present study, we represented that herbs component contained both allergy- enhancing and inhibiting factors, in addition to llergens. We also reported that herbal component such as epigallocatechingallate (EGCG) and epicatechingallate (ECG) is possible to be allergy- inhibiting factors, but the exact mechanism by which they alleviate allergic response is left to be clarifying. Document of allergy enhancing factors and enrichment of allergy inhibiting factors may provide a new approach to diminish allergenicity of various foodstufffs. Clarification of the allergic reaction modifying mechanism of food components and optimization of the intake of allergy modifying factor are necessary for decrement of allergenicity of conventional food and prevention of incidents of allergic response

Along with the development of IOT, the number of people using IOT devices has enormously increased and the IOT era has come. Especially, people using the IP cameras among Internet devices have been drastically increasing. It is because the IP cameras are well networked and comparatively cheap compared with CCTVs, and they can also be monitored and controlled in real time through PCs and smart phones for the purposes of general theft prevention and shop surveillance. However, due to the user's serious lack of security awareness and the fact that anyone can easily hack only with simple hacking tools and hacking sites information, security crimes that exploit those have been increasing as well. Therefore, this paper describes how easily the IP cameras can be hacked in the era of IOT, what kind of security incidents occurred, and also suggests possible government measures and new technical solutions to those problems.

Since the government is fully aware of the specificity and importance of the healthcare field, it operates bureaucracy and affiliated organizations composed of many government ministries and experts and is also handling the related bureaus. However, recent incidents of humidifier disinfectant not only make these government activities unreliable but also cause disappointment to many people. Why did not the government take active measures to ensure product safety? But why was the Korea Centers for Disease Control and Prevention (KCDC) able to speed up the identification of the cause and the recovery of the product? The purpose of this study is to clarify the behavioral mechanisms of government intervention by comparing the behaviors of the Ministry of Trade, Industry and Energy and the KCDC. Then, we will discuss the desirable government structure.

Purpose: Falls are a common cause of unintentional injuries in infants. This study was conducted to examine the patterns of healthcare utilization following infant falls in South Korea. Methods: This cross-sectional descriptive study utilized an online survey designed to gather information regarding the general characteristics of parents and infants, fall-related variables, and healthcare use. Results: The most serious falls identified by parents occurred at an average infant age of 6.97 months. Most fall incidents took place indoors (95.7%), and many occurred under the supervision of caregivers (68.0%). Following the fall, 36.4% of the participants used healthcare services. Logistic regression analysis revealed that healthcare use following an infant fall was significantly associated with being a firstborn child (odds ratio [OR]=5.32, 95% confidence interval [CI], 2.19-15.28) and falling from a caregiver's arms (OR=4.22; 95% CI, 1.45-13.68). Conclusion: To prevent and decrease the frequency of infant falls, improvements are needed in both the domestic environment and parenting approaches.

Since partial discharges in power transformers weaken their insulation performance the detection of partial discharge is very important for prevention of fatal incidents. This study describes use of electromagnetic coupler for measurement of partial discharge of transformers. Spiral antennas of which bandwidth is 0.5GHz to 3GHz were used as coupler and setup in chamber for partial discharge tests. Test results showed that outputamplitudes are increased with PD increase and frequencies of signal measured by these antennas are mostly distributed below about 800MHz.
