The focus of this study is to investigate the effects of R&D employee's four behavioral types in MBTI and working conditions on organizational effectiveness. The results of this study show that organizational effectiveness is influenced by personality types and working conditions. According to the result, First, about the analysis of differences in job satisfaction, EP (Extraversion Perceiving)-type (3.56) and EJ (Extraversion Judging)-type (3.43) are higher than IJ (Introversion Judging)-type (3.07) and IP (Introversion Perceiving)-type (3.03) of four behavioral types in MBTI. So an enterprise makes various efforts to enhance job satisfaction for IJ (Introversion Judging)-type and IP (Introversion Perceiving)-type. Second, For improving the organizational effectiveness that is job satisfaction and immersion, an enterprise must make favorable working conditions to each four behavioral types in MBTI of R&D employees. In order to improve job satisfaction, the enterprise will provide IJ (Introversion Judging)-type with support for collegiality and IP (Introversion Perceiving)-type with good relationships with superiors. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type. Finally, in the case of EP (Extraversion Perceiving)-type, the enterprise must admit failure for efforts. In order to improve job immersion, the enterprise will provide IP (Introversion Perceiving)-type with good relationships with superiors, the vision of company and compensation for creative work. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type.

In this study, the effects of grouping by extraversion and introversion in POE learning applied to elementary science class on students' achievement, the perception of learning environment and the attitude toward science instruction were investigated. Ninety-five 5th graders were assigned to the control group and the experimental groups, and taught about acid and base for 9 class hours. In the experimental groups, the homogeneous small group was composed of four introverts or four extroverts, and the heterogeneous small group was composed of two introverts and two extroverts. Two-way ANCOVA results revealed that the homogeneous group performed better than the control group in the application subtest of the achievement test. Significant difference in learning difficulty was found between the heterogeneous group and the control group. In the attitude toward science class, significant interaction effect was found between the instruction and the extraversion/introversion.

In this study, the effects of grouping by extraversion and introversion in paired think-aloud problem solving using a four-stage problem-solving strategy emphasizing planning and checking stages were investigated. Prior to the instructions, the students' extraversion/introversion in three high school classes (N=87) were examined, and those classes were randomly assigned to the homogeneous, the heterogeneous, and the control groups. The test scores of the two treatment groups were significantly higher than those of the control group in the problem-solving ability. However, there were no significant differences in learning difficulty and self-efficacy. Although there were no significant differences between the scores of two treatment groups in the subcategories of the perception of treatment, the test scores of extroverts were significantly higher than those of introverts in the perception of performing listener's role, the preference to problem solving strategy, and the preference to paired think-aloud problem solving.

The technological environment is rapidly affecting the way of shopping. When consumers go about retail activities, they not only use a single channel (e.g., traditional stores, mobile) but also combine different channels. This research focuses on the factors which influence the favorableness toward omni-channel shopping. Specifically, this paper investigates the effect of extraversion-introversion on the omni-channel shopping favorableness. Moreover, the effect of variety-seeking tendency is examined as a mediator. The results of an experiment using PROCESS program find that when participants are more extravert, they show greater favorableness toward omni-channel shopping and variety-seeking tendency mediates the effect of extraversion-introversion. Based on the findings, this research proposes managerial implications and several directions for further research.

In this study, the effects of extraversion/introversion grouping and the differences between extroverts and introverts in cooperative learning strategy applied to general science class were investigated. Ninety-three 10th-graders were grouped into homogeneous and heterogeneous cooperative groups with respect to extraversion and introversion, and were taught about matter for 10 class periods. Prior to the instructions, three tests regarding the extraversion/introversion, logical thinking, and learning motivation were administered. After the instructions, their achievements, process skills, self-esteem, communication apprehension, and learning motivation were examined. Two-way ANCOVA results revealed that there were no main and interactive effects in the scores of the achievement and the process skills tests. However, significant interactive effect was found in the self-esteem. While the difference in the self-esteem of the introverts and the extroverts was small in the homogeneous group, the self-esteem of the extroverts was higher than that of the introverts in the heterogeneous group. The communication apprehension of the introverts was significantly lower than that of the extroverts. Students' perceptions to their group activities and group members were also studied.

The purpose of this study was to investigate the trait cortical arousal level, measured by extraversion-introversion, in schizophrenics. Subjects in this study were 231 (chronic schizophrenics=78, acute schizophrenics=62, and normal persons=91). All subjects were asked to respond to extraversion-introversion subtest scale in the korean EPQ(Korean Version Eysenck Personality Questionnaire). Collected data were analyzed by using the t-test and one-way analysis of variance. Results were as follows : 1) Trait cortical arousal level of chronic schizophrenics, which was measured by extraversion-introversion subtest scale in the Korean EPQ, was statistically higher than that of acute schizophrenics and normals. 2) Acute schizophrenics and normals were not significantly different in the trait cortical arousal level. However, the trait cortical arousal level of chronic schizophrenics was higher than that of acute schizophrenics. Therefore, it may state that the trait cortical arousal level of schizophrenics is getting higher when schizophrenic symptoms become more chronic.

In this study, MBTI(Myers-Briggs Type Indicator) test was carried out targeting flight instructors and student pilots in charge of introductory flight training course. The results was analyzed in accordance with the personality type, the preferred indicator, and the combination of preferred indicators in order to see how these characteristics affect the flight training results. Most of personality types of the instructor, regardless of the attitude category such as E or I, were -STJ(70.6%), however the student pilot showed a variety of personality types, rather than professors. Sensing-type(S) students showed higher academic achievement scores than Intuition-type(N), and Judging-type(J) students showed higher academic achievement scores and pilot qualification scores than Perceiving-type(P). The success rate of Extraversion-type(E) student pilots was higher than that of Introversion-type(I) student pilots. As the personality combinations of instructor and student pilot, the academic achievement scores of Judging-Judging(J-J) type were higher than those of Perceiving-Perceiving(P-P) type. The combination of Extraversion-Extraversion(E-E) type showed higher success rate than Extraversion-Introversion(E-I). This result suggests that if both instructor and student pilot have same attitude of Extroversion(E), good training results can be expected.

This study examined the association among personality, conflict strategies, and marital conflict. The subjects were 279 married women who completed a questionnaire for 4 personality types(extraversion-introversion, sensing-intuition, thinking-feeling, and judgement-perception), 5 conflict strategies(dominance, integration, compromise, avoidance, and smoothing over), and marital conflict. The results of this study were as follows: 1) Among the women of thinking-feeling type women, the thinking group tended to use more dominance conflict strategy than the feeling group. Among the women of judgement-perception type women, the judgement group tended to use more compromise conflict strategy than the perception group. 2) Results of hierarchical regression analysis revealed that two conflict strategies (dominance and compromise), two personality types (extraversion-introversion and sensing-intuition), and income were significant predictors of marital conflict for married women. Overall, we can conclude that marital conflict is more affected by the strategies for dealing with conflict than by individual personality.

This study, using the free language association method, examined the characteristics of emotional words of respondents who were exposed to facial photos of women in 60s, and favorableness and favorable styles of them. To analyze mood characteristics on the faces, they were divided into positive mood words and negative mood words. Following previous researches, they were divided into introversion, extraversion, and ambiversion. It was found that the proportion of positive emotional words respondents used was 37%, and that of negative ones was 63%, demonstrating that respondents are more likely than not to get the negative impressions from the faces of their contemporaries. The characteristics of the words consists of 38% introversion, 47% extraversion, and 14% ambiversion. And, respondents used the words like 'beautiful' and 'good-looking' to the stimuli to which they felt favorable, and 'ill-tempered' and 'stubborn' to the stimuli to which they felt unfavorable. Third, the most favorable style to both male and female respondents in 60s were sentimental and good-mannered. They generally favor women who are soft and caring, and dislike talkative, snobbish, and thick make-up women. The analysis results in this paper may help image making and personal relations. Further study needs to expand the survey area to ensure more significant influence on the social life and interpersonal relationship of senior citizens.
