Objectives : Lateral epicondylitis on elbow is one of the most common causes of elbow pain. Lateral epicondylitis can be managed with acupuncture, but the evidence for its effectiveness is uncertain. The purpose of this review is to investigate the trends of acupuncture treatments on lateral epicondylitis. Methods : We investigated the studies about acupuncture treatments for lateral epicondylitis via searching 5 Korean web databases(KTKP, RISS, OASIS, KCI, Kisti) The key search terms were 'Lateral epicondylitis', 'Tennis elbow', 'External epicondylitis'. 12 research papers(10 case reports, 1 RCT, 1NRCT) were found to be analyzed according to their published year, the titles of journals, published institution, the types of study, the number of cases, the types of treatments, the instruments for assessment and ethical approvals. The effectiveness of acupuncture treatment was classified. Results : 12 papers were published since 2003. The studies on acupuncture treatments about lateral epicondylitis were mainly published in The journal of pharmacopuncture. 10 case reports, 1 non-randomized controlled trials, 1 randomized controlled trials had been under research. In most of the research, the number of the cases were not enough. In 9 cases of the studies, various korean medicine treatments including acupuncture were used to treat the symptoms. In 3 cases of the studies single method was used to treat the symptoms. Visual analogue scale(VAS) and range of motion(ROM), grip strength were used as primary assessments. Among 12 clinical studies, 1 of them were accepted by institutional review board(IRB). Conclusions : In this study, we analyzed the trends of acupuncture treatments on lateral epicondylitis.

The rapid development of technologies in unmanned aerial vehicles (UAVs) has led to their use in various areas. UAVs are mainly used for commercial purposes, but their utilization is increasingly important in other areas because their operation cost is less than satellites and aerial imaging. The utilization of UAVs in the environment/ecology area is relatively new. Therefore, identifying the trends of UAV-related spatial information is significant in basic research for UAV utilization. This study quantitatively identified domestic and international research trends related to UAV utilization and analyzed research areas. An attempt was also made to identify upcoming UAV-related topics in the environment/ecology research field using text mining to analyze the bibliographic information of global research literature. Domestic UAV-related studies were classified into seven clusters where basic research on "UAV technology/industry trends" was abundant, and studies on data collection and analysis through UAV remote sensing technology have increased since 2015. Eight clusters were identified for international studies where the most active research area international was "remote sensing technology/data analysis". In addition, Canopy, Classification, Forest, Leaf Area Index, Normalized Difference Vegetation Index, Temperature, Tree, and Atmosphere appeared as the main keywords related to environment and ecology. The appearance frequencies and association strengths were high because the advancement in UAV optical sensor technology and the rapid development of image processing technology enabled the acquisition of data that could not be obtained from existing spatial information. They are recognized as future research topics as related domestic studies have begun corresponding to international research.

The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

To study the development trends of domestic apparel design, we analyzed patent applications that were applied to the field of apparel design. It was presumed that economic and social environment have affected directly on the number of apparel design applications. Since year 2000, the whole number of apparel design applications has shown a remarkably increasing tendency, but depending on the items, the trends of patent applications have different tendency. While the number of applications regarding western costume such as a jacket, pants, suit and coat has been increasing from mid 2000s, the number of applications regarding Hanbok and undergarments have been decreasing from mid 2000s. In early 2000s, there were a lot of applications relating to design creation due to combination of color and form in apparel design. However, from mid 2000s, variety of techniques such as granting functional characteristics, asymmetry construction, introduction of various textiles, techniques of draping were being applied in design creation.

Among non-timber forest products, Tricholoma matsutake is a high value added item. Many countries, including Korea, China, and Japan, are doing research and technology development to increase artificial cultivation and productivity. However, the production of T. matsutake is on the decline due to global warming, abnormal temperatures and pine tree pest problems. Therefore, it is necessary to identify trends in domestic and foreign research on T. matsutake, respond to preemptive research and development to preserve the genetic resources of T. matsutake and increase its productivity. Based on the correlation between keywords in the high frequency keywords, it was observed that microbial clusters of T. matsutake are mainly found in Korea. The main focus in China has been the pharmacology studies on the ingredients of T. matsutake. The main focus in Japan has been on preserving the genetic diversity and species of T. matsutake. Thus, future domestic studies of T. matsutake will require pharmacological studies on the ingredients of T. matsutake and on its genetic diversity and species conservation. In addition, unlike China and Japan, genetic keywords did not appear in Korea at high frequency. Therefore, Korea will have to proceed with research using modern molecular biology techniques.
