  • There have existed for a number of years good practice guidelines for the use of Computational Fluid Dynamics (CFD) in the field of wind engineering. As part of those guidelines, details are given for the size of flow domain that should be used around a building of height, H. For low-rise buildings, the domain sizes produced by following the guidelines are reasonable and produce results that are largely free from blockage effects. However, when high-rise or tall buildings are considered, the domain size based solely on the building height produces very large domains. A large domain, in most cases, leads to a large cell count, with many of the cells in the grid being used up in regions far from the building/wake region. This paper challenges this domain size guidance by looking at the effects of changing the domain size around a tall building. The RNG ${\kappa}-{\varepsilon}$ turbulence model is used in a series of steady-state solutions where the only parameter varied is the domain size, with the mesh resolution in the building/wake region left unchanged. Comparisons between the velocity fields in the near-field of the building and pressure coefficients on the building are used to inform the assessment. The findings of the work for this case suggest that a domain of approximately 10% the volume of that suggested by the existing guidelines could be used with a loss in accuracy of less than 10%.

  • A series of centrifuge model tests were performed to investigate the behavior of piled bridge abutment subjected to lateral soil movements induced by the construction of approach embankment. In these tests, both the depth of soft clay and the rate of embankment construction are chosen as key parameters to examine the effects on lateral soil movements. The depth of soft clay layer varies from 5.2 m to 11.6 m, and the rate of embankment construction has two types of staged construction(1m/30days, 1m/15days) and instant construction. It is shown that, the distribution of lateral flow induced by stage embankment construction has a trapezoidal distribution. And practical guidelines to check the possibility of some lateral movement of piled abutment were investigated. The validity of the proposed guidelines by centrifuge test was compared with the observed performance by lateral movement index, F(Japan Highway Public Corporation) and modified I index(Korea Highway Corporation). Based on the results obtained, the critical values of F and modified I, as a practical guidelines, are proposed to 0.03 and 2.0, respectively.

  • Purpose: The Purpose of this study was to build up guidelines for preventing constipation in the Korean elderly based on the National Guideline $Clearinghouse^{TM}$ Guideline. Method: The process is composed of four steps: first. the composition of an expert group; second, the evaluation by the expert group about the appropriateness and applicability of each recommendation in the guideline; third, systematic literature review for evidence searching; and fourth. the formation of guidelines for Preventing constipation in the Korean elderly according to experts' opinions and literature review. Result: The appropriateness and applicability of each recommendation showed high scores, but the score of applicability was lower than that of appropriateness. The reasons for lower score of applicability were lack of cognition on the importance of constipation management and lack of recent information and evidence-based knowledge on constipation. There were some inadequate recommendations in Korean clinical setting. So the modified and replaced recommendations were added to the guidelines for preventing constipation in the old adult population to improve the applicability in Korea. Conclusion: The results of this study can be used as fundamental baseline data for future study to develope guidelines for management of constipation in the elderly and will be adapted locally for Korean clinical setting.

  • The fashion industry has become more interested in sustainable fashion design due to the demand for environmental action based on increased social responsibility awareness and environmentalism. In the current sustainability fashion industry, guidelines for sustainable fashion design are essential. This study suggests guidelines for a sustainable design process based on a theoretical and practical approach. An analysis of several global fashion brands will be applied to the whole apparel design process. This paper will explore the sustainable fashion design process and deal with LCD, as an important factor, by analyzing three global fashion brands: 'H&M', 'NIKE', and 'Levi's'. These three companies are the most active in the area of sustainable performance. The sustainable fashion guidelines will be controlled based on a strategy of practical use in design for sustainable (DFS) fashion industry. The results indicate that the fashion industry has to invest heavily in the future rather than focus on short-term profits; consequently, sustainability is a new growth direction for fashion companies. In addition, the fashion industry should work towards sustainable design under a clear understanding of its goals.

  • A small number of viable tuberculosis bacilli can reside in an individual with latent tuberculosis infection (LTBI) without obvious clinical symptoms or abnormal chest radiographs. Diagnosis and treatment of LTBI are important for tuberculosis (TB) control in public and private healthcare facilities, particularly in high-risk populations. The updated 2017 Korean guidelines for TB recommend that tuberculin skin tests, interferon-gamma release assays, or a combination of them can be used for the diagnosis of LTBI, depending on the age and immune status of the patient as well as their TB contact history. For diagnosis of LTBI, exclusion of active TB is essential, and the possibility of healed TB in those without a history of treatment for TB but at risk of its development must be considered. The treatment options for LTBI include isoniazid, rifampicin, isoniazid/rifampicin, and isoniazid/rifapentine. The benefits and risks of these agents based on the age of the patient and their hepatotoxicity must be considered when selecting the appropriate drug. Standardized diagnosis and treatment of LTBI based on the updated 2017 guidelines will contribute to the control of TB in Korea as well as to further revisions of the guidelines.
