Purpose: The purpose of this study was to examine whether there is difference in the effects of aromatherapy on dysmenorrhea by research design. Methods: Findings from the two different research designs (Nonequivalent control group pretest-posttest [NCG] design vs. two-group crossover design) were compared in regard to the effect of aromatherapy on dysmenorrhea. The subjects of the NCG design and the crossover design were a total of 58 female nursing students. The treatments (aroma essential oil inhalation and carrier oil inhalation) were given using a necklace. The data were analyzed by Fisher's exact test, t-test, Mann-Whitney test, paired t-test, and Shapiro-Wilk test using the SPSS/WIN 12.0 program. The effect size for the two research designs was calculated. Results: In both research designs, the level of dysmenorrhea and menstrual pain after the aroma treatment were not significantly different from those after the placebo treatment. The effect size of the NCG design was higher than that of the crossover design. Conclusion: Aroma inhalation may not be effective in managing dysmenorrhea and menstrual pain. In order to further clarify the efficiency of research design and the effect of aromatherapy on discomfort during menstruation, replication studies are necessary. Future studies need to examine the effects of different research design on non-interval variables.

The purpose of this study is to conduct more practical subsequent research by identifying research areas through a systematic analysis of sustainable fashion design research trends. For this study, 117 journals domestic journals published between 2010 and 2020 were selected using the keyword, 'sustainable fashion'. With the research materials, six top keywords, 'zero waste', 'sustainability', 'eco-friendly', 'upcycling', 'recycling', and 'ethical', were derived. The research status was examined by year, keyword, keyword and year, and research topic. The analysis results are as follows. First, looking into the studies by year, it was found that research on sustainable fashion increased in general. Compared to 2010, the research tripled in 2020, and it was found to have increased steadily from 2018. Second, regarding the research by keyword, eco-friendly was the most common. It can be seen that research tended to focus on recycling or eco-friendliness before, but in later material design development was heading towards upcycling. Third, concerning the research by topic, case studies were found the most before, but research on design development tended to increase recently. Based on that, it is expected that the areas of sustainable fashion design that need more research will be investigated further.

Theoratical and academic research of korean design study started from 1979, the year of establishment of the Korean Society of Design Science. From that point, social contribution and academic research of design study through the academic exchange has been brought up. I collected 2,065 thesises from the 'Journal of Korean Society of design Science' and 'Journal of Korean Society of Basic Design and Art' to analyze the design study tendency during last 24 years. The purpose of this paper is to show the Design study tendency and the direction of the design study with the empirical analysis. The frequency analysis and descriptive statistics were used for the data analysis, and the $X^2$ has been used to verify the differences between the observed frequency and expected frequency of items. The Original articles of design study has been increased steadily because of the growing importance of the design study in the society. The analysis shows Design Foundation Study, Design Application Study and Design Basic Study are the most frequently studied area in the Korean Design Study. Design Study utilize the research methodology of social science to get the reasonable and objective result. Because of this, the number of empirical research method has been increased in the research methodology in Korean Design Study.

As people have paid much attention to their health along with increased interest in high quality of living, they have managed their health in organized manners. Space is a physical field which directly and indirectly interacts with human life, there is a little research on its therapeutic aspect and it is only negatively applied for development of products and alternative medicine. This study aims to identify research trends and flows targeting previous research on therapeutic approaches in domestic space design and present basic materials on space design approaches in a therapeutic view, which will be helpful in ultimate development of space design in theories and practices. As a result, it was discovered that there were only a few papers which were searched with direct key words on curative environment, which indicates that specific studies as therapeutic approaches are insufficient. When the studies were analysed according to annual publications, research on residential welfare and medical space was active, and research on design methodology, design techniques, and design plans was active, but research on psychology, behaviors, laws and institutions was relatively insufficient, which indicates studies on physical and psychological aspects of space design are necessary. In conclusion, it is suggested that further studies on therapeutic environment for direct and specific persons should be defined and classified although there have been relevant studies in various fields.

Interest in the school environment design is increasing as the project to restructure school space and to become common in school through smart devices. However, no research has been presented on the current status of studies on school environmental design, and the need for analysis of recent research trends in school environmental design is required. In response, this study aims to provide basic data on school environmental design by analysing the trends of domestic studies of school environmental design since 2010 and to present the direction of research on future school environmental design. A total of 312 papers related to school architecture and spatial design are set for study in the results of academic information search on school environmental design. Based on this, frequency analysis and cross-sectional analysis are conducted based on the classification table according to the year of issue, research subject, research purpose, and research method. The statistical significance of the research subjects was secured in accordance with the year of issue and subject to study, and accordingly the key research key words were derived. It is meaningful that through this study, the current status of school environmental design research over the last 10 years can be analyzed and the direction for the future school environmental design research has been suggested.

Many thermal-hydraulic tests have been conducted at the Korea Atomic Energy Research Institute for verification of the SMART (System-integrated Modular Advanced ReacTor) design, the standard design approval of which was issued by the Korean regulatory body. In this paper, the contributions of these tests to the standard design approval of SMART are discussed. First, an integral effect test facility named VISTA-ITL (Experimental Verification by Integral Simulation of Transients and Accidents-Integral Test Loop) has been utilized to assess the TASS/SMR-S (Transient and Set-point Simulation/Small and Medium) safety analysis code and confirm its conservatism, to support standard design approval, and to construct a database for the SMART design optimization. In addition, many separate effect tests have been performed. The reactor internal flow test has been conducted using the SCOP (SMART COre flow distribution and Pressure drop test) facility to evaluate the reactor internal flow and pressure distributions. An ECC (Emergency Core Coolant) performance test has been carried out using the SWAT (SMART ECC Water Asymmetric Two-phase choking test) facility to evaluate the safety injection performance and to validate the thermal-hydraulic model used in the safety analysis code. The Freon CHF (Critical Heat Flux) test has been performed using the FTHEL (Freon Thermal Hydraulic Experimental Loop) facility to construct a database from the $5{\times}5$ rod bundle Freon CHF tests and to evaluate the DNBR (Departure from Nucleate Boiling Ratio) model in the safety analysis and core design codes. These test results were used for standard design approval of SMART to verify its design bases, design tools, and analysis methodology.

This paper highlights the importance of design research and encourages an understanding of design tools that engage society and people. Twenty groups, a total of sixty students, were asked to participate in this project and they used an IDEO tool kit. A total of three surveys were given. One survey was given to the participants before participating in the project and another after the project. The last survey was given to six experts to evaluate the students' work. Preliminary analysis found that students, prior to participating in the project, replied heavily on Internet research and a literature review, and did not display a structured research process. Primary analysis showed that the groups that spent more time on research and utilised design tools performed better, particularly those utilising 'observation' techniques.
