This research surveyed 324 college students majored dental hygiene in Gwangju and Chonnam province to analyze their awareness and degree of practice about infection control. Through the study for recognition about infectious disease related with the grade, the sophomore students are the group who is the most aware. In addition, the study shows students who experienced teeth cleaning have high degree of awareness (p<0.05). The research of perception about infectious disease based on experiences for vaccinations and education about infection prevention says hepatitis B has the highest rate when it comes to level of occurrence risk and tuberculosis and acquired immune deficiency syndrome are the lowest (p<0.05). According to the research, the group who had vaccination, knowledge about infection prevention and experience for scaling shows high practice rate for hand washing according to whether students receive protective inoculation or not. Depending on what the result were, since student learned about infection control has high degree of recognition and practice about infection management if we could emphasize the importance to students through regulative education about infection control and then increase the degree of practice, it would make big contributions to the effective infection control.

The stability of firefighting pipes is crucial in the event of an earthquake. In Korea, specification-based designs are used in accordance with NFSC. However, engineering performance-based designs are used for buildings that have special requirements. For firefighting pipes, tree type pipe networks are usually utilized in buildings; however, they are characterized by several limitations. Hence, grid type and loop type networks are being utilized lately. Earthquake-resistant designs for firefighting pipes in Korea utilize NFPA 13 as the cookbook. Nevertheless, an engineering analysis is required to verify its reliability. The NFPA 13 standard used in Korea is a design method for engineers who lack earthquake engineering analysis knowledge of pipes and adapt ASCE and ASME guidelines. Earthquake resistant designs in Korea review braces only. Hence, various analyses under load conditions, such as the internal pressure of a pipe, force exerted by a continuous load, and an earthquake, are required to ensure reliability. An engineering earthquake-resistance analysis showed that tree type pipe networks are less stable than grid and loop type pipe networks. A comparison of earthquake-resistance analysis based on stress and strain revealed that strain analysis exhibited a conservative result value in the range of over-stress. Therefore, for the earthquake-resistance analysis of pipes, it is rational that engineers perform analysis to achieve the required standards through engineering analysis rather than uniform calculations, which should also be analyzed considering various analysis conditions.

The present study was designed to examine fathers' awareness and practice of picture book reading with toddlers. The subjects were 221 fathers who have toddlers, and the data collected by questionnaires were analysed by mean and standard deviation, and frequency analysis. As a result, approximately 59% of fathers stated that it is essential to read to their children who are 12 month old or less, and 36% of fathers answered that they read books as much as their children wanted. The majority considered the emotional aspect of picture book reading as being significant. Also, nearly half (46%) of the fathers read books to their children 1-2 times per week, and 37% of them spent 6-10 minutes at a time reading books. While reading books, 60% of the fathers explained text and pictures to their children and a fourth of the fathers answered their children's questions. Also, while reading books, fathers tried to accept their toddlers' responses positively. However, they did not have much time to read books to their children and had little knowledge on how to read books to infants. Further research and education programs on picture book reading for fathers are needed.

Mega-corporations are emerging as a result of M&As (mergers and acquisitions) in the logistics industry. The global logistics market has progressed in a continuously competitive manner. Global logistics corporations provide integrated set of services, from production to disposal in order to manage the process efficiently throughout the diverse regions of the world. To advance into an total integrated logistics provider, the corporation must have professional knowledge in logistics and information technology which are necessary to deliver effective integrated logistics solutions. The government has integrated the logistics corporations both horizontally and vertically with the aim to foster logistics corporations possessing global competitiveness. Six years have passed since the implementation of the comprehensive (total) logistics industry certification system in pursuit of making Korea the hub for the Northeast Asian logistics market. This study compares and analyzes the efficiency of nine mega integrated logistics providers by applying the CCR model and BCC model. Each of the nine corporations is subject to certification as integrated logistics corporations. In Korea, nine corporations are certified individually as integrated logistics corporations out of the 31 logistics providers. The analysis showed that the Glovis was the most efficient integrated logistics provider reaching 100% in efficiency and displayed the highest efficiency for six consecutive years from 2005 to 2010. The study also found that the Glovis will be able to maintain 100% in efficiency rate, even though the input are increased over six times as many as those of 2010.

Due to habitat damage associated with climate change and human activities, biodiversity has decreased all over the world. In order to prevent further reduction in biodiversity, the international community has endeavored to establish a cooperative system, such as the Convention on Biological Diversity (CBD). Until now, most biodiversity strategic planning has been led by the national government. However, the National Biodiversity Strategy and Action Plan is conservative and its strategic plan is vague. Therefore, we propose a method for managing local biological resources called the Local Biodiversity Strategy and Action Plan. In order to provide the strategic plans and detailed plans for the Local Biodiversity Strategy and Action Plan, the report has examined several cases including Convention on Biological Diversity, Strategic Plan for Biodiversity 2011-2020, and the biodiversity strategies and action plans of the Republic of Korea and several other countries. As a result, the report demonstrates the survey and protection of bio-species, the designation and monitoring of conservation region, the management of the integrated eco-network, the establishment of biodiversity organizations and capacity building, the methods to promote networking and traditional knowledge, and the strategy for development in bioindustry. Consequently, the implementation of biodiversity management strategies by local governments will play a significant role in preserving and increasing biodiversity by realizing the goals of Strategic Plan for Biodiversity 2011-2020.

The purpose of this study is to determine the moderating effect of counseling class experience on the relationship between an undergraduate's personality characteristics, emotional intelligence, and empathic ability. As a result of verification, having course experience has a moderating effect on empathic abilities, reversing agreeableness from positive into negative. It also has a moderating effect on the influence of empathic concern, making that of an extravert positively significant. The experience of taking a course did not show a moderating effect on emotional intelligence that can be improved by learning. This demonstrates that education in counseling as carried out in universities is inappropriate, and course experience enhances empathic concern only when the student tends to be an extrovert. This implies that the current counseling system is a curriculum suitable for extroverted people. Also, when students have a friendly, amicable tendency, the experience of taking a course lowered empathic ability. This means that an amicable tendency is not a variable influencing educational experience, and that the present curriculum needs to be diversified. Although it is hard to provide a curriculum customized for each individual's characteristics, this study holds significance in emphasizing diversity in the curriculum to allow students to choose a small-group class or the lecture method based on personality or individual tendency.

As mobile technologies such as Internet of Things (IoT)-based smart homes and financial technologies (FinTech) are developed, authentication by smart devices is used everywhere. As a result, presence-based biometric authentication using smart devices has become a new mainstream in knowledge-based authentication methods like the existing passwords. The electrocardiogram (ECG) is less prone to forgery, and high-level personal identification is its unique feature from among various biometric authentication methods, such as the pulse, fingerprints, the face, and the iris. Biometric authentication using an ECG is receiving a great deal of attention due to its uses in healthcare and FinTech. In this study, we implemented an ECG authentication system that allows users to easily measure and authenticate their ECG waveforms using a miniaturized wearable device, rather than a large and expensive measurement device. The implemented ECG authentication system identifies ECG features through P-Q-R-S-T feature point identification, and was user-certified under the proposed authentication protocols. Finally, assessment of measurements in a majority of adult males showed a relatively low false acceptance rate of 1.73%, and a low false rejection rate of 4.14%, in a stable normal state. In a high-activity state, the false acceptance rate was 13.72%, and the false rejection rate was 21.68%. In a high-heart rate state, the false acceptance rate was 10.48%, and the false rejection rate was 11.21%.

Technical documents in the construction field are changing from paper documents to electronic ones. As a result, the industry witnesses a trend of using portable electronic devices in searching or retrieving necessary information such as relevant regulations. Despite the improvement in the accessibility to general technical documents, a limitation is still found in accessing the electronic documents on the regulations. We see the barrier for field engineers to enhance their technical knowledge. One of major barriers is that videos, animations, and virtual reality information to enhance the visual understanding of technical content related to regulations are not linked. It is the interactive electronic technical manual (IETM) that can address such issues. The IETM is an electronic document system that enables real-time information acquisition while operating in the form of conversations with users by linking multimedia functions to document types such as specifications and guidelines. This study establishes a model of the IETM that can be operated in the planning stage of a construction project. The study also verifies its usability with a hypothetical case study. This study aims to improve the usability of the IETM in the construction project by analyzing the application effect of the IETM using the AHP technique.

In Korea, life safety assessment through simulation are mandatory in performance-based design. Generally, there are three types of methods for simulation-based life safety assessments: the non-coupling method that compares available safe egress time (ASET) and required safe egress time (RSET) at a specific point through conducting fire and assessment simulations independently; the semi-coupling method that compares fire and evacuation simulation results by overlaying the result screens; and the coupling method that compares the results of fire effect simulation to an evacuation simulation. Of these methods, all designers in South Korea have used the only non-coupling method. In the non-coupling method, it is important to determine the location of a specific point to compare ASET and RSET. However, without any defined regulation, setting the location is determined based on the designer's experience and knowledge. The number of specific locations and the locations themselves differ with each designer, which can produce contrasting results in a life safety assessment. Therefore, this study conducted a life safety assessment based on the three methods (non-coupling, semi-coupling and coupling) and compared each of the results. Furthermore this study suggests a improvement way in particular for the computer simulation.
