  • Native plants thrive naturally in specific areas without human intervention, offering significant potential as genetic resources and biotechnological assets across multiple sectors. To harness this potential, our focus was on analyzing domestic patents related to native plants, investigating their uses, effectiveness, active components, and extraction methods. Using the Korea Forest Service's National Standard Plant List, we gathered data from 988 patents on native plants and 430 patents on the use of native plant seeds. This comprehensive patent analysis aimed to reveal research patterns, technology levels, and emerging trends. The goal is to identify research trends, current technology levels, and provide insights for future patent applications involving native plants.

  • Objectives : For the purpose of developing Korean herbology of the plants to Amaryllidaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article.Methods : Books and research papers about Herbology which published at home and abroad were examined.Results : A list was made about Amarylliaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Amarylliaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Amarylliaceae's properties flavor, channels they use, effects, and toxicity were also noted. Amarylliaceae (grew in Korea) were divided into 4 classes with 16 species. Out of those, 4 classes with 7 species were found serviceable which indicates 44 % of all. Out of all 16 specified Amarylliaceae plants, Lycoris plants were found 9 species, which were shown the most. And 4 classes of Lycoris plants were also selected the most in serviceable Amarylliaceae. Out of all serviceable parts in Amarylliaceae, bulbus parts took first place as 6 species.Conclusions : There were totaled to 4 genera and 16 species in Amarylliaceae in Korea and among them medicinal plants are 4 genera, 7 species, some 44 % in total.

  • Recently, needs for extending remaining life and integrity of the aged energy plants are increased since the most domestic plants have been operated over 10 years. This need makes RAM (reliability, availability and maintainability) of the plant become more significant. RBI (risk based inspection) is main technology to increase RAM in energy plants. So far RBI has been developed mainly in the field of process plants (chemical/refinery), underground buried pipelines or nuclear power plants. However, the existing RBI procedure is limited mainly to process plants, it need to be extended to the other energy plants such as fossil power plants. In this study, a general RBI procedure for optimized PM (preventive maintenance) is proposed for various energy plants.

  • Offset lithography is the most widely used printing process in domestic printing industry, but there are no industry-wide specifications for press control to assure consistent quality across printing plants. As printing becomes more of a commodity and less of an art, it is necessary to develop a print quality specification standard suitable for Korea offset printing field. This study aims to contribute to improving the quality of domestic offset color prints by comparative study on color reproduction properties of 2 kinds of domestic process color ink composed of C(cyan), M(magenta), Y(yellow) and K(black) and of 3 kinds of domestic coated paper, using colorimetric color measurement method.

  • Domestic hydroelectric power plants has been manufactured as the design condition by the demand. Hydraulic turbine power plants operating at appointed load shall be operate stable in terms of pressure, discharge, rotational speed and torque. A performance guarantees for hydro turbines shall be contain, as a minimum, guarantees covering power, discharge and specific hydraulic energy, efficiency, maximum momentary overspeed and maximum momentary pressure and maximum steady-state runaway speed, as well as guarantees related to cavitation. But, present in Korea, the absence of testing laboratories and technical criteria for the performance test of small hydropower degrades the efficiency of the domestic hydropower machines, and makes it difficult to objectively evaluate the performance of hydro turbine. Therefore We planned making a basis of performance test of small hydropower turbine by using our flowmeter calibration system the largest one in Korea. We planned the maximum measurable power of hydro turbine will be 200 kW in our system.

  • To enhance the safety of nuclear power plants, implementation of accident management has been suggested as one of most important programs. Specially, accident management strategies are suggested as one of key elements considered in development of the accident management program. In this study, generally applicable accident management strategies to domestic nuclear power plants are identified through reviewing several accident management programs for the other countries and considering domestic conditions. Identified strategies are as follows; 1) Injection into the Reactor Coolant System, 2) Depressurize the Reactor Coolant System, 3) Depressurize the Steam Generator, 4) Injection into the Steam Generator, 5) Injection into the Containment, 6) Spray into the Containment, 7) Control Hydrogen in the Containment. In addition, the systems and instrumentation necessary for the implementation of .each strategy are also investigated.
