  • This study investigated the influence of time to draw students' mental models and students' field dependence-independence on learning the particulate nature of matter with multiple representations. Seventh graders (N=295) at two middle schools were assigned to control, after-drawing, and before-drawing groups. The students learned "Boyle's Law" and "Charles's Law" for two class periods. Results revealed that the scores of a test on conceptual understanding for the two drawing groups were significantly higher than those for the control group. However, there was no significant interaction between the instruction and students' field dependence-independence in the scores of the test on conceptual understanding. In 'novelty' on a situational interest test, field independent students in the two drawing groups scored significantly higher than those in the control group. The scores for field independent students in each group were similar, while field dependent students in the before-drawing group scored lower than those in the control and after-drawing groups in 'attention demand' on the situational interest test. It was found that most students positively perceived after-drawing or before-drawing, but field independent students in the before-drawing group were more apprehensive about the activities than those in the after-drawing group.

  • This study was performed to investigate some characteristics on human error proneness in the computerized work environment. Our concerning theme was on human error likelihood according to personal temperament. Two experiments were performed. The first experiment was to study the effect of field- independence/dependence on error likelihood. The second experiment was on error proneness. These experiments were performed in information search task. which was most frequent task in computerized work environment such as the control room of nuclear power plant. Ten subjects were participated in this study. Analyzed results are as follows. Field-independence/dependence had a significant effect in both information search time and error frequency. Error proneness had a significant effect in both factors, too. And, a positive correlation was found between error frequency and information search time. These results will be utilized as a basis to study operator's error proneness in the computerized control room of nuclear power plant. later on.

  • The Korean Volunteer Corps (KVC) and the Korean Independence Army (KIA) were Korea's main armed forces that led the independence movement against Japan. KVC members were partly merged into the KIA as the army's first branch in 1942. This study examines two different styles of KVC military uniforms: one that complies with the Uniforms Act of the Army of the Chinese Nationalist government and one that uses the same style without a field cap and a belt. The KIA's first branch had three different uniforms: one similar to that of the KVC, one belonging to the KIA and following the Army Uniform Protocol, and one influenced by the U.S. Army. The KVC and the KIA's first branches had insignias representing their identity. The former wore a distinctive insignia with the corps' name, whereas the latter had a cap badge with Korean national symbols under the Army Insignia Protocol. KVC members who may have initially worn their previous uniform in the early days of joining the KIA later adopted the KIA style. This study is expected to offer basic resources to reproduce KVC and KIA military uniforms and verify the authenticity of related artifacts.

  • Matroid theory, which was first introduced in 1935 by Whitney (2), is a branch of combinational mathematics which has some very much to the fore in the last few years. H. Whitney had just spent several years working in the field of graph theory, and had noticed several similarities between the ideas of independence and rank in graph theory and those of linear independence and dimension in the study of vector spaces. A matroid is essentially a set with some kind of 'independence structure' defined on it. There are several known results concerning how matroids can be induced from given matroid by a digraph. The purpose of this note is to show that, given a matroid M$_{0}$ (N) and a digraph $\Gamma$(N), then a new matroid M(N) is induced, where A⊆N is independent in M(N) if and only if A is the set of initial vertices of a family of pairwise-vertex-disjoint paths with terminal vertices independent in M$_{0}$ (N).(N).

  • High school students' achievements in algorithmic problems, and figure-formatted and textual-formatted conceptual problems concerning stoichiometry, gaseous state, and solution, were measured by the Chemistry Problem Solving Ability Test. The relationships among the achievement scores in the three types of problems and cognitive variables such as logical thinking ability, mental capacity, and field dependence/field independence were examined. The portion of variance of explanation for each achievement score was also studied by a multiple regression analysis. The results showed that logical thinking ability was significantly correlated with the achievement score in the algorithmic problems, and accounted for the significant portion of the variance of the score. Mental capacity accounted for the significant portion of the variance of the score in the figure-formatted conceptual problems. Although field dependence/field independence was significantly correlated with all the achievement scores, it did not significantly account for any scores in multiple regression analyses. However, the magnitudes of correlation coefficients among the achievement scores were higher than those between the achievement scores and cognitive variables. The best predictor for each score was also found to be one of the other achievement scores. Educational implications are discussed.

  • This study examined the experience of middle-aged women, centering on the home as the residence of never-married children. I conducted interviews with four such women in their 50s and 60s who had experienced the residential independence of never-married children within the past five years, and a variety of field texts were used as research texts. Through reconstructing the participants' experiences, two main themes emerged: experiencing anxiety regarding alienation from their child and expecting to resolve this anxiety through the marriage of their child. The participants were anxious about their never-married children, and this study found that at the root of this was anxiety regarding being alienated from their children. The participants often attempted to visit their children's homes to relieve such anxiety but, as their children often discouraged this, the situation was aggravated. Thus, the participants wished for their children to marry, as they aspired to restore an intimate relationship with them through such an event. These results imply that tensions and conflicts between parents and children may arise due to the independence of never-married children.

  • In this study, relationships between student the cognitive affective characteristics and conceptual understanding from individual computer-assisted instruction were investigated. Tests regarding field dependence-independence, learning strategy, self-regulated ability, visual learning preference, goal orientation, self-efficacy on ability, and computer attitude were administered. After having been taught by means of a CAl program, a conception test on molecular motion was administered. It was found that student conceptual understanding was significantly related to field independence, learning strategy, self-regulated ability among the cognitive characteristics and visual learning preference, goal orientation, self-efficacy on ability among the affective characteristics. Multiple regression analysis of the cognitive characteristics on conceptual understanding found that field dependence-independence was the most significant predictor. Self-regulated ability and a deep learning strategy were also found to have predictive power. Lastly, analysis of the affective characteristics, visual learning preference and self-efficacy on ability exposed them to be significant predictors of student conceptual understanding.

  • This study investigated the effects of the prescribed instructional strategy for reducing students' connecting errors in learning chemistry concepts with multiple external representations by students' field independence-dependence. Seventh graders (N=126) at a coed middle school were assigned to control and treatment groups. The students learned "Boyle's Law" and "Charles's Law" for two class periods. Results revealed that the students in the treatment group scored significantly higher than those in the control group in a conception test. The scores of the treatment group were significantly higher than those of the control group in a motivational learning test, especially in 'attention' of the test. However, there was no significant interaction between the instruction and students' field independence-dependence in the two tests. Most students in the treatment group perceived the instruction positively in cognitive and motivational aspects.

  • This paper aims to reveal the merits and demerits of the exhibition by examining whether the subject intended at the exhibition planning stage was finally persuasively implemented throughout the work and exhibition, along with the theoretical verification of the way the exhibition dealing with the history of the women's independence movement from the psychoanalytic feminist point of view. To this end, a more fundamental approach to the theme of the Women's Independence Movement calls for the search for a feminine language that can capture women's unique identity rather than a masculine language such as the existing independence movement exhibition method, and for finding such feminine language, a feminine speech, art and poetic language, maternal genealogy, and women's solidarity are presented, along with theories. This paper, which expounds the role of art works in exhibitions dealing with history through theoretical verification of actual exhibition cases, has significance as communication between theory and field.

  • The limitation and scarcity of broadcasting waves provide important rationale behind the idea of public ownership of broadcasting waves which can facilitate communications among people with diverse backgrounds and values in the society. Independence of broadcasting industry from the regulatory organization is imperative for the broadcasting industry to serve the public interest that has been historically defined by each county. For the Korean broadcasting industry, history of modern Korea taught us that the broadcasting regulatory organizations such as Korea Communications Commission(KCC) should be kept from any political influence for the industry to best serve the public. Recent controversies on the role of the CEO of KBS and the appointment of the CEO of YTN by the president of the country provide evidence that the independence of broadcasting in Korean society is a critical topic. This study examined the corporate structures of broadcasting industry and the political independence of the industry in relation to the changes in the concept of public interest and the role of broadcasting. It is critically important to investigate the political independence of broadcasting in Korea because the core argument of independence of broadcasting which is about the freedom of expression protected by the constitution is still contested in the country. For the purpose of collecting diverse perspectives on broadcasting, survey method was adopted in this study. Three groups Abstracts 697 of participants were recruited: reporters, experts in the field, and regular citizens. The result indicated that the independence of broadcasting was in the process of deterioration. Also, the participants of the study understood that it was impossible for the broadcasting to serve the public interest when the broadcasting was not free from the influence of regulatory institutions such as KCC.
