Bidirectional transport trend using the sediment-transport path model was identified in the two areas, sand ridge area and tidal mudflat in Garolim Bay, which is located in the mid-western coast of Korean Peninsular. This model exhibits the two-dimensional view of clear sediment transport trend based on data of changes in sediment statistics such as mean, sorting, and skewness, Garolim Bay was selected to test for the sediment-transport path model developed by McLaren and Bowles [1985]. Line-S, a typical tidal mudflat and representative of the Garolim Bay tidal flats, is well tested by this model, showing a clear seasonal change and coarsening-trend seaward (case C). This indicates that strong ebb currents carried relatively coarser sediments seaward with respect to high energy regime. Seasonally, this energy regime slowly decreases toward the summer in contrast with an increase of energy regime of flood tides, carrying coarser sediments landward (case C) in the summer. However, the Line-D area does not show consistent transport trend with respect to time-series. Separated and scattered events show fining trend landward (case B) in the sand ridge itself. The finining-trend (case B) either seaward and landward is not chiefly important in both the entire Line-D area and sand ridge itself. Also, the coarsening-Trend (case C) landward is not significant in the sand ridge itself. Consequently, in reality, the selection of suitable and representative locations are very important to fit with this model.

This paper was aimed to review the research trends on the subject of ′landscape′ that were published in the Journal of the Korean Institute of Landscape Architecture (KILA) over the 30 years from 1973 to 2003. The total number of articles with the "landscape" subject is 132(12.1%) out of 1,089(the total number of articles). The ratio of the ′landscape′ articles to the total number of the two decades between 1980 and 1999 increased at 8.7% and 1.1% respectively, and decreased at 5.3% since 2000. It was found that each decade showed its own trend of research subject. The first trend during the 1980′s focused on the methodology of analyzing the characteristics of landscape. The second trend during 1990′s converged to the positivistic research method, which relies on computer technology. A new and very important trend began during the same decade. It was "visual landscape planning", which attracted much attention since the operation of local autonomy in Korea. This trend focuses on ′visual landscape planning′, and it is expected to grow drastically in the near future. Therefore, it is recommended that we promote the more elaborate methodology of ′visual landscape planning′, which also includes the ecological and cultural aspects of the environment.

This study attempted to investigate the research trend of MLD studies which were issued from 2001 to March 2022 by research period/area/method/purpose through the analysis of academic theses and journals and use the results for the growth and of MLD. The study results found the followings: First, in terms of the results by research period, a total of 84 academic papers and journals were published: Phase 1 (15), Phase 2 (47), Phase 3 (22). Second, when analyzed by research area, 'cosmetology' was the highest with 19 papers in terms of the number of studies. In fact, the field of study accounted for the largest portion in all three phases. Third, when analyzed by research method, quantitative research showed the largest percentage in all three phases. Fourth, when analyzed by research purpose, a practical approach was dominant with 81 papers out of the total number of 84 (3 papers in theoretical approach). Concerning a domestic MLD-related research trend, it is an essential step for MLD study establishment and qualitative improvements. Such research analysis of MLD studies is meaningful in that it has not been attempted before. In addition, it is anticipated that the study results would be helpful in searching a direction for the academic growth and development of MLD.

Traditional korean medicine which has long history and many clinical experiments stands out in bold relief because the medicine's point of view has been changed from medical treatment to disease protection and the wellbeing life through health care and complementary alternative medicine has been emerged for the incurable disease. Many traditional korean medical research has been conducted in the fields of preventive medical application, leading material drawing and medical service upgrade through eastern and western medical treatment and the more advanced project are being studied as time goes by. But because we have the hardship of manifesting traditional korean medicine's knowledge into detailed data and information in the field of analytical science and we don't have well arranged research trend data of it, researchers are using much time to survey the preceding research and planners needing more accurate research trend data to protect duplication and raise efficiency. So we have studied the traditional korean medicine's research trend to solve this problems by the method of bibliography applied for the preceding project results. Through the analysis of traditional korean medicine's 370 project reports we came to a conclusion that the R&D investment is concentrated on the university and research institute, the utilization projects are lower than basic and applied research, regional snobbism is excessive than the whole nation's R&D and advanced project has been started since 2006.

The purpose of this paper was to study interior design research trend through categorizing the research in interior design process and investigating the research method used at each stage of the process. The ultimate aim was to evaluate the relationship of design process and interior design research and to indicate the guide line of future research. As results of the study, interior design research did not reflect recently increasing renovation and remodeling trend since evaluation research was less performed than data collection, program and design development research. Only educational/research space showed higher rate in evaluation research. In recent years, interior design research is interested in objective design problem solving since programming research Increased, and in user-participation planning since questionnaire and interview research Increased as data collection method. For the future research, it is expected researchers to show creative thinking process on the stage of design development and to develop various research method on the stage of evaluation.
