I attempted to study the resolution of how I can show the essence of an original musical production to audience, the possibilities of how recreate impossible elements according to Korean musical environment because of cultural and linguistic differences, and verify the meaning of adjusting an original production to Korean one through directorial approaches to licensed musical production. I mainly exemplified 2009 Korean production (Charlotte Theatre, March ~ August, 2009) that I directed. The purpose that I wanted to analyze the case of Korean production mainly is able to prove a wide variety of possible challenges rather than simply licensed ones because the former was recreated in 30 years after the first original production. Recreation and coaching to acting through fine and precise analysis of an original production, Koreanizing Western culture of the licensed musical, resolving the problem of linguistic nuances are the important ways to direct licensed musical. For licensed musical director, cooperation with original creative team and Korean production company must be the most important job.

Objectives The purpose of this study is to investigate clinical studies on the efficacy and safety of herbal medicine inhalation therapy in children by analyzing recent randomized controlled trials conducted in China. Methods We searched the clinical studies from the China Academic Journal (CAJ) in China National Knowledge Infrastructure (CNKI) using a by key word '霧化吸入' and specific criteria from 1st January 2010 to 2nd July 2019. Data regarding years of publication, demographic information, target diseases or symptoms, treatment methods, outcome measure, results and adverse events are collected for this study. Results Total of 44 randomized controlled trials were selected and analyzed. Respiratory diseases and symptoms (84.1%) were the most frequent target diseases that herbal medicine inhalation therapy was used. Acute stomatitis was another disease state that the therapy was used. In most of the studies, the herbal medicine inhalation in children showed significant efficacies. The most commonly used herbal medicines were Ephedrae Herba (麻黃), Lonicera Flos (金銀花), Armeniacae Semen (杏仁), Glycyrrhizae Radix et Rhizoma (甘草), Scutellaria Radix (黃芩), Forsythia Fructus (連翹) etc. Hardly any adverse effects were reported from the trials selected. Conclusions Based on the results of the clinical studies from China, herbal medicine inhalation therapy in children can be an effective and safe option for treatment and symptom improvement.

In this study, there are regional limitations for the fine dust data provided by public data to represent the wide area air quality. It is about a method that can provide detailed data in a specific area beyond location restrictions. The goal of this implementation is to mount the IoT-based fine dust sensor on a quadcopter that can fly autonomously beyond the positional limitations of the current measuring station, which is fixed, and quickly move the fire-generating area and the area of rapid fine dust to make detailed measurements. Through this, the system is designed and implemented to enable the fundamental analysis of the occurrence. We designed a QDMS system and proposed a method to measure detailed changes in fine dust at a specific location through manufacturing and experiments.

Modular structures are relatively lightweight compared to reinforced-concrete or steel structures. However, it is difficult to achieve structural integrity between the columns of unit modules in a modular structure, which causes undesirable effects on the lateral force resistance capacity against wind and earthquake loads. This is more prominent in modular structures whose overall heights are greater. Hence, a post-tensioned modular structural system is proposed herein to improve the lateral force resistance capacity of a typical modular structure. A post-tensioned column-base connection, which is the main component of the proposed modular structural system, is configured with shapes and characteristics that allow inducing self-centering behaviors. Finite element analysis was then performed to investigate the hysteretic behaviors of the post-tensioned column-base connection. The analysis results show that the hysteretic behaviors are significantly affected by the initial tension forces and beam-column connection details at the base.

A site containing buried solid waste and treated water and oil storage containers from a leather manufacturing plant was studied through soil and groundwater pollution and electrical resistivity surveys with the aim of identifying areas polluted by leachate generated by landfilling with leather waste and leakage wastewater. It was found that TPH and Zn exceeded environmental standards for soil pollution and, for leachate and groundwater, Cr(VI) concentrations exceeded standard levels for groundwater quality. An electrical resistivity survey was used to elucidate soil and groundwater pollution characteristics and diffusion pathways. Ten survey lines were set up with an electrode spacing of 5 m in a dipole-dipole array. The hydraulic characteristics of soil determined by groundwater contamination surveys matched well the low-resistivity-anomaly zones. Electrical resistivity surveys of areas containing contaminated soil and groundwater that have irregular strata due to waste reclamation are thus useful in highlighting vertical and horizontal pollutant diffusion pathways and in monitoring contaminated and potentially contaminated areas.

Cracks, which account for the largest proportion of defect lawsuits in apartment buildings, are not clear on the criteria for defect determination, so judgments about defects are mixed. Interlayer cracks, which account for most of the crack defect judgment amount, tend to be judged as defects regardless of the crack width or condition, and repair methods are mostly set uniformly. This starts from the problem that the standards of the Ministry of Land, Infrastructure and Transport and the Construction Appraisal Practice, which the courts use as standards, do not match. It is necessary to establish a defect determination standard that can be applied to all stakeholders through the amendment of laws and the revision of the Court Appraisal Practice. In addition, it is necessary to apply the crack repair method according to the width and condition of the interlayer crack. If the defect determination and the application of the repair method for cracks are rationalized, it could serve as an opportunity to change the current trend of defect disputes that rely only on litigation.

The seismic responses of traffic light poles are investigated using a finite element analysis. Among the traffic light poles, single- and bi-directional traffic light poles are considered since such poles are frequently installed on vehicle roads. For a more detailed investigation, three different lengths of the mast arm are considered for each directional pole. For a time-history analysis, six actual and two artificial earthquakes are considered and applied to each direction of the poles (x and y) to investigate which direction input provides more significant responses due to the unsymmetrical structural shape. Herein, the x and y directions are respectively parallel and perpendicular based on the single mast pole case. From the analysis results, the average maximum displacement response is developed with the x-direction input case for both types of light poles. Also, the bi-directional traffic light poles show a 13% larger response than the single-directional traffic light poles. Even though the y-direction input case produces a smaller response, the response difference between the single- and bi-directional light poles considerably increases by about 60%. The average maximum acceleration responses are almost similar for both types of light poles.

This study entailed an investigation of a tensile stress measurement method for prestressed concrete (PSC) tendons by utilizing external magnetization. The target of this study are PS structures that have been constructed and in use. An optimal external magnetization based elasto-magnetic (EM) sensor was designed using finite element analysis considering various factors, such as coil arrangement and size, that could influence the PS tendons inside the PSC girder. The residual tensile stress resulting from the external magnetization of the girder was then determined. Further, theoretical verification was performed using the numerical and material data used in the finite element analysis for sensor design. The calculated values of strength of magnetization at the target location were matched with the finite element analysis results. Thus, the designed sensor and the feasibility of magnetizing the tendons inside the PSC I-girder using an EM sensor were validated.
