  • Among several NMR hyperpolarization techniques, parahydrogen-based hyperpolarization technique is recently extensively utilized to enhance the sensitivity of the conventional NMR/MRI spectroscopy. Two mostly investigated research topics are PHIP (Parahydrogen Induced Polarization) and SABRE (Signal Amplification By Reversible Exchange), which are commonly using the parahydrogen as the source of hyperpolarization. Those researches have been considered as the promising techniques that could provide hyperpolarized states on the ambient substrates including biologically important materials. Therefore, based on their potentials, we briefly reviewed several important experimental results on those topics after introducing the basic principle of parahydrogen and its generation with conceptual explanations. We hope this review will broaden the parahydrogen-based hyperpolarization transfer study on many researches in Korea.

  • Recently, the usage of polymer concrete mortar gathering an interest as a new construction material rapidly increases inside and outside of the country because it is an environment-friendly and endurable material. However, up to these days, the researches about the polymer composite have not been satisfactorily conducted. The polymer concrete is superior to the general cement materials in the properties of strength and durability while it is inferior in elastic modulus. Because that the members using the polymer concrete have therefore higher strength and ductility than the members of general cement concrete, an analysis equation of high-strength cement concrete can be referenced but it is not applied for the researches about the polymer concrete members. In this study, the flexural properties of T-shaped beam of the steel- and GFRP-reinforced polymer concrete are analyzed to examine the suggested analysis equation. Results of this experimental researches are to be used as the basic data in a structural design of the polymer concrete.

  • Plastics have become essential materials in human life for several decades. Meanwhile, the inadvertent spread of plastic debris from the use of many plastic products has raised global environmental concerns. The risk of microplastics in subsurface environment has received little attention because soil is considered to confine microplastics within the matrix. However, the concentration of microplastics in soil unavoidably increased as a result of an increase in plastic production and use. Based on lab experiments, several researches claimed that microplastics possibly penentrate soil layers. Recently, a few researches reported the occurrence of microplastics in groundwater. This study reviewed the recent reports of microplastic occurrences in soil and groundwater, and the modeling studies for simulating transport of microplastics. Additionally, the difficulties and limits in microplastics researches in soil and groundwater are discussed. Finally, several perspectives on microplastic studies in subsurface environment are suggested.

  • This thesis intends to suggest a new wedding dress pattern through researches on history and changes of wedding dress, researches on silhouette and details and analyses of existing basic patterns. In this study, to develop torso patterns of top dresses selected as preferred designs through literature reviews and company surveys, dress form sizes suitable for standard sizes were selected and study basic patterns were made using draping techniques. The study finds characteristics of body type dimension that is changed when wearing brassiere (hereinafter, 'bra') for wedding dress through customer surveys for development of basic patterns of wedding dress. That is, wearing wedding bra was used for the purpose of increasing the bust size and we will evaluate later whether this increase helps completeness of aesthetic impression through wearing evaluation. As the result, it was found out that top torso pattern wearing wedding bra made wearers feel more comfortable and in the aspect of aesthetic impression, it provided impacts on women's beautiful silhouettes. The effects of whether a bra is used or not on changes in patterns were reviewed through the degree of polymerization of finished patterns. When a bra for dresses was worn, the waist front length increased by1.7cm, the bust circumference increased by 2.1cm, and the amount of dart increased by 1.5cm in the patterns. A new torso pattern for top dresses, which will solve problems evaluated in each of the above from the aspect of composition of pattern by a method through analysis of existing basic patterns and multi-dimensional cut patterns wearing wedding bra, will be suggested.

  • The effect of red tide on the marine ecological system is so severe that many researches on the diverse subjects related to it have been conducted. Notwithstanding the enormous efforts and inputs the results of the past researches show no clear ways to deal with the HAB problems. As many researches are being conducted, the efficient and appropriate research project management systems as one of the critical factors for successful research are also needed as well as the fund and the capabilities of the researchers. It is assumed that the development of the evaluation and management systems for red tide research projects is so important and critical to enhance the researches and to utilize efficiently the physical and human resources for research. In this respect this study aims to present the evaluation and management scheme for the red tide researches that can not only decide the priority of the research subjects and tell the desirable research directions, but also support to develop the useful managerial policies and guidelines for the policy maker. The main subjects dealt with in this study are as follows : the characteristics of the HAB researches, the basic attributes and criterion of the research evaluation systems, the structure and design of the evaluation systems, and the development of the managerial policies by the type of the evaluation system. The conceptual scheme developed in this study is expected to be applied to the related areas and can suggest to the policy makers so many implications for identifying and setting the proper policy objects and management techniques. This study has a couple of weak points. It suggests only the conceptual scheme but not the applications so that the researches focusing on the applications in practical perspectives are needed to follow.

  • The purpose of this study is to explore the interior therapy that introduced the concept of therapy into interior space. This study examines interior therapy based on the concepts of stress and therapy. As the study methods, a qualitative analysis to review the concept of interior therapy was conducted together with a quantitative analysis on the current state of domestic therapy-related researches. The scope of the study is limited to domestic journals published from 1988, when the first domestic research was embarked on to analyze the current status of therapy-related researches, until November 2016. According to the study results, the domestic therapy-related studies were mainly focused on aromatherapies and food therapies. By year, the first domestic study of its kind was conducted on logotherpay in 1988. And until 2000, studies were carried out mainly on aromatherapies. Since then, new psychotherapy research fields have emerged; color therapy in 2003 and food therapy in 2008. However, in the space design field except for color therapy-related researches, there have been not sufficient studies on the indoor space therapy field that investigates the possibility of indoor space as a therapy from an integrated viewpoint. Therefore, this study reviewed domestic researches on interior therapy which applied the concept of therapy to interior design and suggested three cognitive-emotional-behavioral measures as healing factors. Finally, this study is expected to be used as basic data for design planning and curriculum development which apply the concept of therapy to interior design-related fields.
