  • Recently, shipping operators have been making efforts to reduce the fuel cost in various ways, such as trim optimization and bulb re-design. Furthermore, IMO restricts the hydro-dioxide emissions to the environment based on the EEDI (Energy Efficiency Design Index), EEOI (Energy Efficiency Operational Indicator), and SEEMP (Ship Energy Efficiency Management Plan). In particular, ship speed is one of the most important factors for calculating the EEDI, which is based on methods suggested by ITTC (International Towing Tank Conference) or ISO (International Standardization Organization). Many shipbuilding companies in Korea have carried out speed trials around the Korea Straits. However, the conditions for these speed trials have not been exactly the same as those for model tests. Therefore, a ship’s speed is corrected by measured environmental data such as the seawater temperature, density, wind, waves, swell, drift, and rudder angle to match the conditions of the model tests. In this study, fundamental research was performed to evaluate the ship resistance performance due to changes in the water temperature and salinity, comparing the ISO method and numerical simulation. A numerical simulation of a KCS (KRISO Container ship) with a free-surface was performed using the commercial software Star-CCM+ under three conditions that were assumed based on the water temperature and salinity data in the Korea Straits. In the simulation results, the resistance increased under low water temperature & high salinity conditions, and it decreased under high water temperature & low salinity conditions. In addition, the ISO method showed the same result as the simulation.

  • To evaluate the fundamental factors in the recovery of biogas from the landfills composed of about 40% of volatile solids, the experiments for the samples from the operating landfill site as well as from the laboratory-scale lysimeter were undertaken. In the test of landfills, the change of moisture content, the content of volatile solids (VS), the ratio of saccharide to ligin(Y) and the estimation of landfills reclaimed and the correlationship between VS and Y were investigated. During the experiments with laboratory-lysimeter, temperature, pH, gas production rate, the composition of gas were measured. The mathematical model derived from the the rate coefficient of gas production(k) were proposed from the results of this investigation. Furthermore, the proposed mathematical model from this study was verified with the obtained values from experiments.

  • The purpose of this study is to first discriminate and assess those infants who appear healthy in appearance but who could face possible risk factors in the future and, secondly, to identify those infants who may have difficulties in their developmental stages. The subjects of this study consisted of 35 full-term infants (39-40 weeks) and 33 pre-term infants (34-35 weeks). The infants' voices were recorded for three minutes, for which EDIROL by Roland and a stand-type microphone made by SONY were used. This was done to discern the value of the Breath unit (B-unit) and the fundamental frequencies ($F_0$). It was found that there were significant differences in terms of F0 since the pre-term infants had higher F0 than the full-term infants, showing a result of 436.4 Hz for the full-term infants and 460 Hz for the pre-term infants (p<.05) There was an average rate of 4.01 for the full-term infants and 4.02 (SD=1.69) for the pre-term infants in shimmer. For NHR, it was observed .44 for the full-term infants and .50 for the pre-term infants, thus revealing no significant differences in these observations. This study shows that the crying of newborn babies is related to their physical conditions and it is a sensatory response to these conditions. Furthermore, this study could be helpful for the early detection and measurement of newborn babies who look clinically healthy but could be at risk through acoustic and physiological analyses.

  • The expenses of maintenance and reinforcement for aged concrete structures are significantly on the increase as their durability and general performance has been naturally degraded. Due to this reason, interests on concrete crack reduction technology are growing but more researches are required to fulfill such fast growing demands. Particularly in the underground power facilities, it is difficult to maintain the quality of aging concrete spheres for underground power as their deterioration caused by long-term operation is on-going. In recent years, many studies have been made to overcome the issues and now it is determined that the shrinkage reducing technology which can dramatically reduce the crack at the design stage is one of the most effective solutions. In this study, the test investigated fundamental propertiesof concrete using various shrinkage reducing materials to develop low shrinkage mortar. According to results of experimental study, for mortar and concrete, glycol based material showed excellent shrinkage property and compressive strength. For the later study to generic application of the shrinkage reducing materials, performance reviews on the shrinkage reducing materials with variable factors and various materials such as changes in the amount and type of materials should be followed.

  • Downscaling is a fundamental procedure in the assessment of the future climate change impact at regional and watershed scales. Hence, it is important to investigate the spatial variability of the climate conditions that are constructed by various downscaling methods in order to assess whether each method can model the climate conditions at various spatial scales properly. This study introduces a fundamental research from Jang and Kavvas(2015) that precipitation variability from a popular statistical downscaling method (BCSD) and a dynamical downscaling method (MM5) that is based on the NCAR/NCEP reanalysis data for a historical period and on the CCSM3 GCM A1B emission scenario simulations for a projection period, is investigated by means of some spatial characteristics: a) the normalized standard deviation (NSD), and b) the precipitation change over Northern California region. From the results of this study it is found that the BCSD method has limitations in projecting future precipitation values since the BCSD-projected precipitation, being based on the interpolated change factors from GCM projected precipitation, does not consider the interactions between GCM outputs and local geomorphological characteristics such as orographic effects and land use/cover patterns. As such, it is not clear whether the popular BCSD method is suitable for the assessment of the impact of future climate change at regional, watershed and local scales as the future climate will evolve in time and space as a nonlinear system with land-atmosphere feedbacks. However, it is noted that in this study only the BCSD procedure for the statistical downscaling method has been investigated, and the results by other statistical downscaling methods might be different.

  • This essay explores the ways in which the philosophical concept of "original form" is expressed in relevant laws and regulations, the legal character of respective regulations, the way in which each regulation is applied in practice for heritage management, and the factors required for this concept to serve as a legally binding fundamental principle. The current laws and regulations on heritage maintain a consistent requirement for preserving the original form of heritage, both for the general public and for heritage professionals. However, the principle of preserving original form is expressed as a declaration or imperative without substantive definitions. Consequently, heritage administrators simply follow administrative procedures for heritage conservation, management, and promotion while failing to specify the meaning of "original form." For the practical application of the principle of preserving original form to overall heritage conservation activities as an actual legal principle, further provisions should be added for the purpose of clarifying the principle, with consideration given to the observation of fundamental principles for legal provisions, such as the principles of clarity, equality, and proportion. The principle of preserving original form still functions as the most necessary principle for heritage conservation and therefore should be reestablished as a refined and rational regulatory system.

  • Objectives: This study was conducted to investigate dental hygienists' knowledge of smoking, attitudes toward tobacco cessation, and tobacco cessation education activities, which will serve as fundamental data for developing an effective tobacco cessation education program for dental hygienists. Methods: From 2020-08-17 to 2020-09-05, 184 dental hygienists working at dental clinics and hospitals in Gwangju and Jeollanam-do were surveyed. We performed t-tests, ANOVA, Pearson's correlation analysis, and multiple regression analyses. Results: Dental hygienists' smoking-related knowledge, expert attitudes toward tobacco cessation, and tobacco cessation education activities were all high in tobacco cessation education (p<0.05). According to the analysis of the dental hygienists' knowledge of smoking, attitude toward smoking, and correlation of tobacco cessation education activities, there was a significant amount of correlation (p<0.01). According to the analysis of factors affecting dental hygienists' tobacco cessation education activities, expert attitudes towards tobacco cessation (𝛽=0.434, p<0.001), tobacco cessation materials (𝛽=0.160, p=0.009), experience in tobacco cessation education while attending school (𝛽=0.152, p=0.010), and attitudes toward tobacco cessation (p<0.05) were statistically significant. Conclusions: The results of this study are utilized as fundamental data to develop an effective tobacco cessation education program, factoring in dental hygienists' attitudes toward tobacco cessation.

  • In this study, a fundamental-level study was performed to establish knowledge-base for the development of optimal surface-wave method for urban areas with adjacent structures. First, theoretical modelling was performed to investigate the influence of adjacent structures on dispersion characteristics of surface waves. Later, the geotechnical sites with a concrete model of adjacent structure and a real subway box structure were tested by surface-wave method to investigate the influence of adjacent structures. The major influencing factors of adjacent structures on surface-wave propagation were direct distance between measurement array and adjacent structure, stiffness contrast between layers and type of seismic source.

  • Congestion is a growing concern of many global cities and the demands on Infrastructure services within a locale coupled by the rising expectations from the growing population places stress on these cities. This entails the ability to build a sustainable community that requires an understanding and recognition of Population growth, changing demographics and the ever changing urban development on both a macro and micro level. Infrastructure is an integral part of Australian economy, particularly the 'Infrastructure Assets Management' which highlights the importance towards the development of sustainable communities for Melbourne's future. Melbourne 2030 is a comprehensive representation of government's response to a wide-ranging population growth within Melbourne metropolitan and surrounding areas. Urban plan and specific Infrastructure Assets Planning needs not only to provide sufficient Infrastructure to a community, but it must also be efficient and innovative so that it produces an optimised management system. A system that incorporates engineering techniques that will be sustainable for decades to come by maintaining an acceptable level of services to its intended community in an effective manner, which also strengthens service delivery. The fundamental challenges for optimization of Infrastructure with the Melbourne urban plan is, the ability to manage and sustain maintenance of Infrastructure to provide the acceptable level of service required by the community in a most effective manner which also strengthens service delivery to contribute towards Melbourne 2030. This paper particularly investigates some of the fundamental issues within the Melbourne urban plan such as Infrastructure Asset Management, AusLink and the Australian Road Management Act 2004, which the Governments at all levels must deal with to provide an economically viable solution to the changing Infrastructure so it may suits the needs and services the strategies of a metropolis.
