  • Hurricanes and tornadoes are the most destructive natural disasters in some central and southern states. Thus, storm shelters, which can provide emergency protections for low-rise building residents, are becoming popular nowadays. Both FEMA and ICC have published a series of manuals on storm shelter design. However, the authors found that the materials for related products in the market are heavyweight and hard to deliver and install; renovations are necessary. The authors' previous studies found that lightweight and high-performance composite materials can withstand extreme wind pressure, but some building codes are designated in wind-borne debris areas. In these areas, wind debris can reach greater than 100 mph speed. In addition, the impact damage on the composite materials is an increasing safety issue in many engineering fields; some can cause catastrophic results. Therefore, studying composite structures subjected to wind debris impact is essential. The finite element models are set up using the software Abaqus 2.0 to conduct the simulations to observe the impact resistance behavior of the carbon fiber composite sandwich panels. The selected wood debris models meet the FEMA requirements. The outcome of this study is then employed in future lab tests and compared with other material models.

  • The majority of construction site incidents occur due to a lack of hazard awareness among workers on job sites. This lack of awareness is despite mandatory construction safety training, typically in the form of written content (safety manuals) or of images depicting hazards. To reduce job-site injuries and fatalities, general contractors have started adopting Virtual Reality (VR) to impart safety training to job site personnel. VR safety training can take the form of an immersive simulation comprising potential safety hazards intentionally embedded into a virtual job site; users are required to identify these hazards within a specified time frame with the expectation that they will be more adept at recognizing hazards on an actual job-site, resulting in fewer accidents. This research study seeks to identify the actual impacts of VR on construction safety awareness among participants. The research addresses the following question: Does VR improve hazard recognition awareness? The primary objective is to evaluate participants' performance of past construction safety awareness against present construction safety awareness after receiving VR training. Participants were asked to complete a multiple-choice Qualtrics™ questionnaire. The results of the study showed a statistically significant knowledge gain advantage with respect to hazard recognition and construction safety awareness with the use of interactive, immersive VR over a more conventional and passive safety training method.

  • Citizens' demand for public CCTVs continues to rise, along with an increase in variouscrimes and social problems in cities. In line with the needs of citizens, the Seoul Metropolitan Government began installing CCTV cameras in 2010, and the number of new installations has increased by over 10% each year. As the large surveillance system represents a substantial budget item for the city, decision-making on location selection should be guided by reasonable standards. The purpose of this study is to improve the existing related models(such as public CCTV priority location analysis manuals) to establish the methodology foranalyzing priority regions ofSeoul-type public CCTVs and propose new mid- to long-term installation goals. Additionally, using the improved methodology, we determine the CCTV priority status of 25 autonomous districts across Seoul and calculate the goals. Through its results, this study suggests improvements to existing models by addressing their limitations, such as the sustainability of input data, the conversion of existing general-purpose models to urban models, and the expansion of basic local government-level models to metropolitan government levels. The results can also be applied to other metropolitan areas and are used by the Seoul Metropolitan Government in its CCTV operation policy

  • Purpose: This study aimed to analyze the counseling status of overseas Koreans using emergency medical counseling services, identify frequently occurring types of diseases, explore approaches to emergency treatment guidance, and protect overseas Koreans from medical blind spots, thereby enhancing the quality of emergency medical counseling services. Methods: This study was approved by the Institutional Review Board of Kongju National University (KNU_IRB_2023-31), and data were collected and analyzed from 10,951 cases of emergency medical counseling services utilized by overseas Koreans from the National Fire Agency from 2018 to 2022. Results: Emergency medical consultation services for overseas Koreans included a majority of non-trauma patients, with medical consultations being predominant. Terrestrial patients commonly seek advice for internal medical symptoms, whereas maritime patients frequently present with trauma-related symptoms, with a higher incidence of cardiac arrest and altered consciousness cases at sea. The development of self-diagnostic tests based on internal medicine symptoms is necessary for terrestrial patients, whereas stakeholder education is required for maritime patients. Conclusion: Due to the different types of diseases occurring in terrestrial and maritime patients, emergency medical consultation services for overseas Koreans should be implemented according to the specific characteristics of each patient. Therefore, it is necessary to develop and disseminate response manuals that are tailored to medical and trauma-related symptoms.

  • The recent surge in the production and handling of hazardous materials in Korea necessitates developing and implementing robust emergency response plans. These plans are crucial in safeguarding the well-being of workers and residents in the event of an incident. The consequence analysis methodology outlined in the KOSHA guidelines provides a foundation for designing emergency response plans in the event of chemical accidents. However, the consequence analysis is evaluated based on assumed accident cases or worst-case scenarios. Consequently, the emergency response plan based on the consequence analysis may overestimate the damage area, complicating rescue efforts and unnecessarily increasing costs. More information and parameters become available after an accident, enabling more accurate consequence analysis. This implies that the results of consequence analysis based on this detailed information provide more realistic results than those based on assumed accidents. This study attempts to optimize the resource allocation and cost-effectiveness of emergency response plans for chemical accidents. Existing procedures and manuals are revised to elucidate the proposed model and conduct real-time consequence analysis. The existing emergency response plan is compared to verify the proposed model's efficacy. The obtained results indicate that the proposed model can exhibit better performance.

  • Conventional culture-based methods of enumerating rumen microorganisms (bacteria, archaea, protozoa, and fungi) are being rapidly replaced by nucleic acid-based techniques which can be used to characterise complex microbial communities without incubation. The foundation of these techniques is 16S/18S rDNA sequence analysis which has provided a phylogenetically based classification scheme for enumeration and identification of microbial community members. While these analyses are very informative for determining the composition of the microbial community and monitoring changes in population size, they can only infer function based on these observations. The next step in functional analysis of the ecosystem is to measure how specific and, or, predominant members of the ecosystem are operating and interacting with other groups. It is also apparent that techniques which optimise the analysis of complex microbial communities rather than the detection of single organisms will need to address the issues of high throughput analysis using many primers/probes in a single sample. Nearly all the molecular ecological techniques are dependant upon the efficient extraction of high quality DNA/RNA representing the diversity of ruminal microbial communities. Recent reviews and technical manuals written on the subject of molecular microbial ecology of animals provide a broad perspective of the variety of techniques available and their potential application in the field of animal science which is beyond the scope of this treatise. This paper will focus on nucleic acid based molecular methods which have recently been developed for studying major functional groups (cellulolytic bacteria, protozoa, fungi and methanogens) of microorganisms that are important in nutritional studies, as well as, novel methods for studying microbial diversity and function from a genomics perspective.

  • It is not easy to access to the required data from the Web by using search engines because there are too many data selected and they do not provide enough information related to the corresponding data. Metadata is data about data. It includes information about data itself and contents of data as well. Users can acquire enough information about the corresponding data and access to the required data exactly using metadata, and therefore the data usability will be increased. In this paper, several metadata technologies and metadata models that are already in process of standardization or adopted as standards are analyzed, and the SeriCore Metadata Model for documents such as papers, project reports, technical reports, abstracts, and manuals, and graphic images that are in the field of science technologies on the Web is proposed. The SeriCore Metadata Management System that can generate, store, and retrieve metadata effectively is designed and implemented based on the SeriCore Metadata Model.

  • BIM(Building Information Modeling) ordering manuals and guidelines are diffused with the recent BIM activation. However, it is causing drawbacks such as an increase of work at each design stage and a decline of BIM application level that the standard of making up and managing BIM is vague and it includes comprehensive meaning. Therefore, this study aims to secure BIM work standard by establishing BIM making-out standard based on LOD(Level of Detail) classification considering domestic design process. It compared each definition of LOD by analyzing domestic and foreign BIM guideline examples, and figured out insufficiency of existing domestic and foreign design process and BIM guidelines. Moreover, it drew architects' work articles for promoting the progression of the efficient design process, and analyzed BIM requirements on design process, dividing BIM application scale by field. Through this analyzing process, it finally established BIM making-out standard classified by design process. The effects of establishing BIM making-out standard would include improving a division of labor and cooperation environment by creating integrated BIM model on design stages, advancing work efficiency by preventing a repetition and an increase of work, and upgrading project completeness and design quality. Besides, it can secure BIM work standard by clarifying responsibility for working steps. BIM making-out standard established by this study will contribute to developing the future BIM work standard document and BIM guideline as a data base.

  • The purpose of this study was to assess the hygiene status of 145 child-care foodservices, which were newly registered in the Center for the Children's Foodservice Management (CCFSM) in Changwon, Gyeongnam. Sanitary inspection checklist (40 food safety items) of Korea Food and Drug Administration (KFDA) was used by the CCFSM in Changwon, Gyeongnam. Average score from the total safety items in 145 child-care foodservices was 21.41 points out of 40 points. Score gaps between the lower group (71 foodservices, 13.92 points) and higher group (74 foodservices, 28.61 points) showed a significant difference (P<0.001). The top five priorities of sanitary measures needing corrective actions for child-care foodservices were as follows: 'provide hand washing and sanitizing tools, and supply manuals on how to wash hands properly', 'supply record form for access/inspection', 'conduct education for cooks on standards in the selection of sanitizer for raw vegetables and proper methods to wash and sanitize raw vegetables', 'provide a refrigerator and a freezer with installed thermometers and temperature record monitoring logs', 'encourage separation of contamination operating zone and clean zone or conduct training for cooks on ways to prevent cross-contamination by performing work separately by the hour'. For the higher group, most were national/public facilities (83.3%), whereas in the lower group, private facilities (62.1%) were more common than national/public ones (37.9%). Therefore, a significant difference (P<0.001) was detected in the two groups. These private facilities should be supported.
