The purpose of this study is to investigate the trends of character-related research in science education by analyzing science education research literatures in South Korea. To this end, literatures on character were extracted from the KCI-listed journals and theses from 1990 to December 2016, and analyzed according to the criteria such as terms relating to character, year of publication, research design and method, and research content. A total of 54 KCI-listed papers and 67 theses were extracted. As a result, 46%, 49%, and 5% of the researches include the terms like character, ethic, and moral in their titles. According to the year of publication, it was found that the number of research papers related to character increased rapidly by more than two times in 2012 as compared to the past years. According to research objects, researches about gifted students were the most common, and when considering the ratio of gifted students to general students, many studies related to character concentrated on gifted students. Starting 2009, research papers on qualitative and hybrid research design begin to advance as compared the number of papers in quantitative research design. With regards to research methods used, seven methods were classified; five of them ranged from 16% to 19% while interpretive research method was 12% and test tool validity study was the lowest at 2%. By extracting 30 representative keywords so as to analyze the contents of character-related researches, we found various implications to character in relation to nature and researches about SSI, etc. As time passed by, the contents of character-related research in science education became more diversified and the number of researches increased. New research contents appeared due to the needs of the times.

The study was carried out to analyze the fracture behavior and the acoustic emission(AE) characteristics and to find the relationship among tensile strength, fracture toughness and cure pressure in owe process of the carbon fiber reinforced composites of two types, $[0^{\circ}/90^{\circ}]_{2S}$ and $[0^{\circ}\;_2/90^{\circ}\;_2]_S$. AE signals were detected during the curing process, tensile tests and fracture toughness tests by acoustic emission(AE) measurements, respectively. Tensile strengths showed that the less cure pressurizing steps and the side of $[0^{\circ}/90^{\circ}]_{2S}$ specimens had the higher strengths than those of the others. Fracture toughness by the change of test temperature showed nearly same values in the same temperature region, but the higher test temperature had the lower fracture toughness values. In order to examine the relationship between fracture behavior of CFRP in tensile and fracture toughness tests and AE signals, the post processing for AE parameters of AE data and the observations of microscope and SEM have been carried out respectively.

Fracture process of continuous fiber reinforced composites is very complex because various fracture mechanisms such as matrix cracking, debonding, delamination and fiber breaking occur simultaneously during crack growth. If fibers cause crack bridging during crack growth, the stable crack growth and unstable crack growth appear repeatedly. Therefore, it is very difficult to exactly determine tile starting point of crack growth and the fracture toughness at the critical crack length in composites. In this research, fracture toughness test for CFRP was accomplished by using acoustic emission(AE) and recording of tile fracture process in real time by video-microscope. The starting point of crack growth, pop-in point and the point of unstable crack growth can be exactly determined. Each fracture mechanism can be classified by analyzing the fracture process through AE and video-microscope. The more reliable method ior the fracture toughness measurement of composite materials was proposed by using the combination of R-curve method, AE and video microscope.

Recently the primary water stress corrosion cracking(PWSCC) has occurred in the dissimilar metal weld region between pressurizer nozzle and safe-end in nuclear power plants(NPPs). As material of the pressurizer nozzle, SA508 Gr. 3 low alloy steel was used. F316L stainless steel and Alloy 82/182 were used as safe-end and weld metal, respectively. Although mechanical properties are needed for evaluation of the structural integrity against flaw in the material, material specification and standard don't supply those properties. Therefore, the present study conducted tensile and fracture toughness tests on SA508 Gr.3 and F316L stainless steel at ambient temperature and operating temperature of NPPs and reported the tested results.
