  • Objective : The purpose of this study was to analyze the trend of clinical research on 'mild and sub-clinical depressions' in China. Method : The journal search was performed using China National Knowledge Infrastructure(CNKI). Our inclusion criteria were as follows: TCM clinical trials for mild, sub-clinical, early stage of depression. Exclusion criteria were the following: non-TCM clinical trials, disease-associated depression related clinical trials. Results : We included 16 papers in this study. 1. In this study, we realized there have been several mild and sub-clinical depressions related clinical trials conducted in the field of TCM. 2. The result of 10 Journals used the Hamilton Depression Rating Scale for diagnosis and assessment criteria of mild and sub-clinical depressions. 3. The selected journals categorized by various interventions, such as, herbal medicine(7), acupuncture(4), miscellaneous(5). 4. Also, 7 Journals showed the significant improvements in patients with mild and sub-clinical depressions by TCM interventions, and 5 studies of TCM patent prescription reported that herbal medicine therapy has less side effect than the western medicine. Conclusion : Through this study, we found out that several researchers in China performed clinical trials on mild and sub-clinical depressions constantly. From the result of this study, we need to concern about the necessity of research on the mild and sub-clinical depression in Korea. Therefore, this result could be used as a meaningful reference for the design of future clinical trials.

  • Metal prices are rapidly rising due to increasing demand of metals and limited available resources according to the industrial requirement. As a result, securing a stable supply of these metal resources has been recognized as a core element of national competitiveness and sustained economic growth. In the case of magnesium and its alloys which are entirely depending on import, low-grade magnesium scraps from end-of-life vehicles and 3C(Camera, Computer, Communication) parts and magnesium wastes such as sludge and dross generated during melting process are hardly recycled. Accordingly, the development and commercialization of recycling technology of low-grade magnesium scrap is desperately needed to improve efficiency of resource circulation and to establish the required proprietary of resource metal supply and demand. In this study, papers and patents on recycling technologies of waste magnesium were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1974 to 2012. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.

  • Approximately 8.5 million tons of fly ash and 740,000 tons of briquette ash were produced in 2010. Inefficient recycling of coal ash has been a heavy economic and environmental burden and economical coal ash utilization technologies are required to turn coal ash into valuable resources. In this study the patents and literature were analyzed to understand the present situation of coal ash recycling technologies and to promote utilization of coal ash for producing a non-sintering green cement, geopolymer. The survey was based on the open patents of USA, European Union, Japan and Korea, and the papers in SCI - indexed journals published between 1979 and 2013. Technical key words were used for data collection and noise filtering. Trends of recycling technologies in utilization of coal ash for producing geopolymers were discussed in terms of time periods, countries, companies and various forms of technologies.

  • Global climate change and urbanization have various demerits, such as water pollution, flood damage, and deterioration of water circulation. Thus, attention is drawn to Nature-based Solution (NbS) that solve environmental problems in ways that imitate nature. Among the NbS, urban wetlands are facilities that perform functions, such as removing pollutants from a city, improving water circulation, and providing ecological habitats, by strengthening original natural wetland pillars. Frequent monitoring and maintenance are essential for urban wetlands to maintain their performance; therefore, there is a need to apply the Internet of Things (IoT) technology to wetland monitoring. Therefore, in this study, we attempted to develop a real-time wetland monitoring device and interface. Temperature, water temperature, humidity, soil humidity, PM1, PM2.5, and PM10 were measured, and the measurements were taken at 10-minute intervals for three days in both indoor and wetland. Sensors suitable for conditions that needed to be measured and an Arduino MEGA 2560 were connected to enable sensing, and communication modules were connected to transmit data to real-time databases. The transmitted data were displayed on a developed web page. The data measured to verify the monitoring device were compared with data from the Korea meteorological administration and the Korea environment corporation, and the output and upward or downward trend were similar. Moreover, findings from a related patent search indicated that there are a minimal number of instances where information and communication technology (ICT) has been applied in wetland contexts. Hence, it is essential to consider further research, development, and implementation of ICT to address this gap. The results of this study could be the basis for time-series data analysis research using automation, machine learning, or deep learning in urban wetland maintenance.

  • This study collected applications, registered girdle patents, utility models, and design rights using the keyword girdle, and analyzed the application period, applicant, and technical classification of girdle patents, utility models, and design rights. This was done to extract basic data necessary for the development of functional girdles and to set the direction of research. From 2001 to 2005, girdle-related patents, utility models, and design rights applications were the most common. Individuals were the most common applicants, and the technical fields of girdle-related patents and utility models included human necessities, textiles, and paper products. Design rights were most often categorized as underwear, lingerie, corsets, bras, sleepwear, etc. The implication was that technology was required to subdivide the girdle function and to provide convenience in putting on and taking off the girdle. In addition, there was a lack of technical research on sewing methods, accessories, and functional fabrics, and research in these areas was required. In future research, it is thought that it is necessary to set the direction of technology development through research on foreign technologies.

  • ICT is the main driving force of Korea's economic growth. Korea has the world's best ICT competitiveness, and several policies are being implemented to maintain it. However, for successful policy implementation, it is crucial to understand ICT trends accurately. Therefore, this study analyzes the trends of 18 core technologies in the ICT field. In particular, the degree of scientific development and commercialization by technology are investigated through research paper analysis and patent analysis, respectively. Then, the trends shown by document type are compared based on the two analysis results. As a result, artificial intelligence and virtual reality are at the stage where commercialization is actively taking place after scientific development, and at the same time, since research is being conducted, it is expected to develop continuously. On the other hand, quantum computer and implantable device are in the basic research stage. It is necessary to understand the current research status and determine the direction of future support. The results of the ICT trend analysis conducted in this study can be used as a criterion for determining the future direction of Korean policy.
