DEAD/DExH-box RNA helicases catalyze the folding and remodeling of RNA molecules in prokaryotic and eukaryotic cells, as well as in many viruses. They are characterized by the presence of the helicase domain with conserved motifs that are essential for ATP binding and hydrolysis, RNA interaction, and unwinding activities. Large families of DEAD/DExH-box proteins have been described in different organisms, and their role in all molecular processes involving RNA, from transcriptional regulation to mRNA decay, have been described. This review aims to summarize the current knowledge about DEAD/DExH-box proteins in selected protozoan and nematode parasites of medical importance worldwide, such as Plasmodium falciparum, Leishmania spp., Trypanosoma spp., Giardia lamblia, Entamoeba histolytica, and Brugia malayi. We discuss the functional characterization of several proteins in an attempt to understand better the molecular mechanisms involving RNA in these pathogens. The current data also highlight that DEAD/DExH-box RNA helicases might represent feasible drug targets due to their vital role in parasite growth and development.

관례의 전력계통에서는 스위칭 컨트롤러, 반도체 전력변환 설비, 사무 자동화 기기, PC 등으로 인하여 중성선에 많은 양의 영상 고조파가 발생하게 된다. 이러한 중성선 영상 고조파 전류를 줄이기 위하여 리액터의 일종인 NHER (Neutral-line Harmonics Eliminating Reactor)를 설계하고 해석하는 연구를 수행하였다. C++프로그램을 활용하여 NHER의 설계프로그램을 개발하였고, 설계프로그램을 확인하기 위해 380/220[V], 200[A]의 모델을 적용하여 설계 및 해석하였다. 최적화 설계 결과 철손이 26[%] 저감되었고, 특히 9 고조파는 다른 고조파에 비하여 크게 감소하였다. NHER을 설계할 때에는 실제 적용되는 부하의 영상고조파나 효율 등을 고려하면 더 좋은 결과가 나올 것이다.

In Korea, the $6^{th}$ industrialization in the agricultural sector has increased farmers' income and value-added agricultural products. Local governments, including Chungcheongnam-do, as well as the Ministry of Agriculture, Food and Rural Affairs, introduced the $6^{th}$ industrialization to the agricultural sector and operated various programs for the $6^{th}$ industrialization in the agricultural sector. Recently, the capacity of human resources for the $6^{th}$ industrialization in the agricultural sector became one of the important problems which might limit the effect of the $6^{th}$ industrialization in Korea. Chungcheongnam-do introduced an education program in 2018 to improve the capacity of people who work for the $6^{th}$ industrialization in the agricultural sector. However, researchers have rarely studied or discussed the current status of this education program. The aims of this paper were to analyze the current status of the education program for the $6^{th}$ industrialization in the agricultural sector through a survey, frequency analysis and analytical hierarchy process (AHP) and to present a way to improve the effect of the education program. The results of this study are as follows: First, the students in the education program were generally satisfied with the lectures and achieved knowledge and social networking among the students. Second, practical lectures, including practice and field experience, need to be expanded for the students instead of theory lectures. Third, networking between students and experts should be strengthened.

Some essential components in nuclear power plants are periodically inspected using non-destructive examinations, for example ultrasonic, eddy current and radiographic examinations, in order to determine their integrity. These components include nuclear power plant items such as vessels, containments, piping systems, pumps, valves, tubes and core support structure. Steam generator tubes have an important safety role because they constitute one of the primary barriers between the radioactive and non-radioactive sides of the nuclear power plant. There is potential that if a tube bursts while a plant is operating, radioactivity from the primary coolant system could escape directly to the atmosphere. Therefore, in-service inspections are critical in maintaining steam generator tube integrity. In general, the eddy current testing is widely used for the inspection of steam generator tubes due to its high inspection speed and flaw detectability on non-magnetic tubes. However, it is not easy to analyze correctly eddy current signals because they are influenced by many factors. Therefore, the performance of eddy current data analysts for steam generator tubing should be demonstrated comprehensively. In Korea, the performance of steam generator tubing analysts has been demonstrated using the Qualified Data Analyst program. This paper describes the performance demonstration program for steam generator tubing analysts and its implementation results in Korea. The pass rate of domestic analysts for this program was 71.4%.

Methods: The questionnaire for the survey was distributed to 300 students, who were enrolled in culinary education program at Seoul Institute of Technology and Education from September 5, 2014 to September 20, 2014, and 264 responses were used for analysis. Results: Awareness regarding Yaksun food was low, but the intention to participate in the Yaksun food class was high. The information searching route for Yaksun food was mainly television, radio or internet. Memil-jeonbyeong ssam was the most eaten menu item and Nokdu-Samgye tang was the most popular menu item. Among the different types of Yaksun food, vegetable dishes, steamed dishes, rice dishes and roasted dishes were preferred in this order. The most preferred educational institution for Yaksun food was the cultural center, and the most preferred educational period for Yaksun food was less than three months. The most important point in the Yaksun food class was practical application in real life. Also, the current state of usage for Yaksun food and the intent to participate in an education program for Yaksun food was statistically different according to demographic characteristics. With respect to the current state of usage for Yaksun food, the information searching route for Yaksun food was statistically different according to occupation, cooking career and lives and Yaksun cuisine type preference according to gender, occupation, income and households. Also, with respect to education program participation intention for Yaksun food, educational institution preference for Yaksun food was statistically different according to gender, age, occupation, cooking career, income and lives. Conclusion: Based on these results, this research concludes that for developing an educational program for Yaksun food, it is important to analyze the target customers' demographic characteristics and their needs. Furthermore, it shows that there is a need to develop various educational programs and menus for Yaksun food.

Thin film electrodes have been intensively studied for active materials and current collectors to enhance the electrochemical performance. Here, porous structures of nickel-based oxide films, consisting of nickel oxide and copper (II) oxide, which was derived from the copper substrate during the annealing process, were deposited on metallic copper foils. The half-cell tests revealed excellent capacity retention after $80^{th}$ charge/discharge cycles. Some films showed an excess of the theoretical capacity of nickel oxides, which mainly originate from partially oxidized copper substrates during annealing. These results exhibit that both a preparation method of an active materials and partially oxidized current collectors could be important roles to apply thin film electrodes.

Demand for construction technology is expected to change due to changes in domestic and foreign construction markets and the fourth industrial revolution. In particular, demand for project management strategy and project management capability is even more increasing rather than existing production technology capability. However, the current re-education program for engineers and technicians in construction industry is not matching the need of improving capacity required to reflect the demand of construction technology from construction industry. Therefore, in this study, as a part of efforts in innovating the current global construction talent re-education system to cope with the change in the construction industry, we analyzed the difference between the demand of construction technology and the present condition of construction re-education program. In order to investigate the current status of re-education of construction, questionnaires were prepared to gather opinions from construction engineers who attended construction re-education program and also from industrial partners that are jointly doing business. This study can be an example to improve the construction re-education program as a system for substantially reinforcing the competence of engineers rather than those programs that are merely verifying and/or extending engineers' certification.
