The purpose of this study was to examine the relationships between MMPI(Minnesota Multiphasic Personality Inventory) scale and safety and health related indices in the shipbuilding workmen. The MMPI scores of the 230 shipbuilding workmen applicants and their performance records regarding safety and health were analyzed through t-test and one-way ANOVA to obtain the following results; (1) applicants intended to show the positive characteristics of their personality, and this attitude reflected a decrease on T-scores of MMPI; (2) there were significant relationships between some MMPI subscales and safety & health related indices. These results can be used to provide baseline information for more effective accident prevention programs.
The objective of this study was to develop a paper strip which could determine E. coli qualitatively and quantitatively in water, wastewater, drinks, or food. This paper strip method was a simple and rapid test method that determine E. coli by visual identification. In this study, nutrient culture media were formulated and characterized for optimum conditions. Paper strips were then prepared by impregnating into the media and dried at $60^\circ$C. The test procedure is quite simple to use. The paper strip was dipped into a sample, and excess sample was removed. The strip was then incubated at $37^\circ$C for 16 to 20 hours and the number of colonies on the strip was counted. The color of the colony spots produced by microorganisms varied depending on the media formulation. Violet-red spots were produced by E. coli. The test method was simple, rapid and no special laboratory equipment was necessary for visual identification. Therefore, this test method is applicable to on-site tests such as field tests or home tests. The paper strip method was compared with the standard agar plate method and Japanese commercial product. The method of the economical preparation of test strips was studied for production on industrial scale.

The purpose of this study was to develop and evaluate a teaching learning process plan for the practice of caring and sharing to improve character of highschool students through Home Economics subject. The teaching learning process plan consisting of 13-session lessons has been developed and implemented according to the ADDIE model for the unit of 'Happy Family Life and Culture led by Family'. The unit was divided into two themes: Theme I caring through sharing and Theme II caring through practice. Six practice elements of caring and sharing such as communication, gratitude, courage, love, empathy, and environment drawn from Theme I are applied to Theme II. Various activities and teaching materials as well as questionnaire were developed. The plan was applied to 8 classes, 287 freshmen of S highschool in Jeonju-si from March to May, 2014. Three factors were drawn from 35 character-related items: self-perception, perception of caring and sharing, and practice of caring and sharing. These factors were related to respondents' satisfaction with family relationships and school life. Two factors except self-perception improved through 13 lessons. Students evaluated that the whole caring and sharing practice lessons of Theme I and II gave them the chance to realize a actual practice in everyday life was important even with small efforts such as cooking for special family. Also students commented that the praising workbook was impressive. All 23 items of evaluation gained from over 3.5 to 4.2 on 5-point scale. It can be concluded that the teaching learning process plan for the practice of caring and sharing for the unit of 'Happy Family Life and Culture led by Family' would improve character of highschool students through the Home Economics subject.

This study aims to investigate how flipped learning-based socioscientific issue instruction (FL-SSI instruction) affected middle school students' key competencies and character development. Traditional classrooms are constrained in terms of time and resources for exploring the issues and making decision on SSI. To address these concerns, we designed and implemented an SSI instruction adopting flipped learning. Seventy-three 8th graders participated in an SSI program on four topics for over 12 class periods. Two questionnaires were used as a main data source to measure students' key competencies and character development before and after the SSI instruction. In addition, student responses and shared experience from focus group interviews after the instruction were collected and analyzed. The results indicate that the students significantly improved their key competencies and experienced character development after the SSI instruction. The students presented statistically significant improvement in the key competencies (i.e., collaboration, information and technology, critical thinking and problem-solving, and communication skills) and in two out of three factors in character and values as global citizens (social and moral compassion, and socio-scientific accountability). Interview data supports the quantitative results indicating that SSI instruction with a flipped learning strategy provided students in-depth and rich learning opportunities. The students responded that watching web-based videos prior to class enabled them to deeply understand the issue and actively engage in discussion and debate once class began. Furthermore, the resulting gains in available class time deriving from a flipped learning approach allowed the students to examine the issue from diverse perspectives.

Objectives: The current study investigated the personality characteristics of parents of children with attention-deficit hyperactivity disorder (ADHD) using the Minnesota Multiphasic Personality Inventory (MMPI), which is commonly used in clinical medicine. Methods: Participants were 117 parents of children with ADHD (96 boys and 21 girls) and 77 parents of comparison children (50 boys and 27 girls), who completed the Korean version of the MMPI. Results: The MMPI scores of the fathers of ADHD children were significantly higher on the Psychopathic Deviate (Pd), Masculinity-Femininity (Mf), Paranoia (Pa), and Psychasthenia (Pt) scales than the comparison group's were. In addition, the mothers of ADHD children had higher MMPI scores on the traits of Hypochondriasis (Hs), Psychopathic Deviate (Pd), and Schizophrenia (Sc) than the comparisong roup had, but were not significantly higher. Conclusion: The fathers of ADHD children might be antisocial, irresolute, passive, paranoid, and anxious. In addition, mothers of ADHD children might have hypochondriacal, antisocial, and/or psychological confusional traits, but these were not be significantly high. These results suggest that the psychopathology of parents of ADHD children might correlate with their children's ADHD.

Objectives:The purpose of this study is to 1) conduct a discrimination analysis of schizophrenia and bipolar affective disorder using MMPI profile through artificial neural network analysis and logistic regression analysis, 2) to make a comparison between advantages and disadvantages of the two methods, and 3) to demonstrate the usefulness of artificial neural network analysis of psychiatric data. Procedure:The MMPI profiles for 181 schizophrenia and bipolar affective disorder patients were selected. Of these profiles, 50 were randomly placed in the learning group and the remaining 131 were placed in the validation group. The artificial neural network was trained using the profiles of the learning group and the 131 profiles of the validation group were analyzed. A logistic regression analysis was then conducted in a similar manner. The results of the two analyses were compared and contrasted using sensitivity, specificity, ROC curves, and kappa index. Results:Logistic regression analysis and artificial neural network analysis both exhibited satisfactory discriminating ability at Kappa index of greater than 0.4. The comparison of the two methods revealed artificial neural network analysis is superior to logistic regression analysis in its discriminating capacity, displaying higher values of Kappa index, specificity, and AUC(Area Under the Curve) of ROC curve than those of logistic regression analysis. Conclusion:Artificial neural network analysis is a new tool whose frequency of use has been increasing for its superiority in nonlinear applications. However, it does possess insufficiencies such as difficulties in understanding the relationship between dependent and independent variables. Nevertheless, when used in conjunction with other analysis tools which supplement it, such as the logistic regression analysis, it may serve as a powerful tool for psychiatric data analysis.

Background: Although the cause of hyperhidrosis has not been the subject of close investigation, there are cases for which excessive sweating happens at the hands, feet and armpits due to hyperactivity of the sympathetic nervous system. This usually occurs in people less than 25 years old and it often causes difficulties for their social and occupational life and there is a decrease in the quality of life. Therefore, this should also be examined according to the mental state of the patient who suffers from hyperhidrosis. Methods: The Minnesota Multiple Personality Inventory was administered to 59 patients in the Hyperhidrosis Center from March, 2006 to March, 2007. The MMPI's validity and 10 clinic standards were analyzed. The results were compared according to gender and age. Results: Of the standard clinical items, psychopathy and conversion hysteria were 21.1% and 17.5%, respectively. On comparison between males (47.5%) and females (52.5%), the females had a higher score for the hypochondriasis item. The patients above 18 years old had a significantly higher level of hypochondriasis and hypomania compared to the patients below 18 years old. Conclusions: When analyzing the personality of the patients with essential hyperhidrosis with using the MMPI, it was difficult to look for relations with the mental factor. Therefore, it is necessary to develop diagnostic tests for younger people with considering the relations with the period of morbidity.
The purpose of this study was to develop and validate future teacher competencies diagnosis tools required for pre-service teachers. In this study, the hypothesis model was established by hierarchizing basic competency and job competency in three dimensions such as knowledge, practice, and personality as teachers' competencies required in future society. Based on this hypothesis model, 54 preliminary questions were developed, and competencies diagnosis test was conducted for 237 pre-service teachers in J area, Korea. The results of this study are as follows: First, as a result of this study, a total of 53 questions were extracted, including 18 questions with 6 factors in the knowledge dimension, 17 questions with 6 factors in the practice dimension, and 18 questions with 6 factors in the personality dimension. Second, the goodness-of-fit of future teacher competencies diagnosis model required was verified, and convergence and discriminant validity were verified. The results of this study were discussed. Finally, the implications and suggestions for further research were presented.
The purpose of this study is to propose the possibility of integrating creativity and character education and its need in mathematics education by developing and validating a testing tool assessing students' perceptions of mathematical creativity and character. For this purpose, we developed sixty questions in total to extract factors of mathematical creativity and character based on a literature review. Then, questionnaire data were collected for 1258 middle school students. After the collected data were randomly divided into two (n1=615, n2=643), the first group of data was used for exploratory factor analysis and the second one was employed for confirmatory factor analysis. As a result, 45 problems showing nine factors were extracted. The cognitive components of creativity includes divergent thinking, convergent thinking, imagination/visualization, and reasoning, whereas its affective components are interest, motivation, and openness. The character components contain participation, communication, responsibility, and promise. In addition, it is concluded that the developed testing tool, in which character in the model of this study impacts creativity meaningfully, has a measurement consistency which is not affected by gender and grade differences. These results have implications for a guide to curriculum development promoting creativity and character at school by showing objective and practical foundations of helping how to integrate creativity and character education.
Objectives : The Minnesota Multiphasic Personality Inventory (MMPI) is a commonly used psychological test measuring personality and psychopathology in both clinical and non-clinical population. This study was to evaluate characteristic MMPI-2 profile associated with the risk of suicide among college students. Methods : We analyzed the survey response of 2,964 college students who participated in a health survey from a school health center at a national university in 2011. Those who endorsed any of six items on the suicidaity module of MINI were classified as a suicide risk group and remaining students who did not as a control group. Then we compared the Patient Health Questionnaire (PHQ-9) score, the MMPI-2 Clinical scales and Restructured Clinical (RC) scales. To evaluate the correlation RC scales with suicidality score, Pearson correlation analysis was performed. Results : The suicide risk group was 464 students, and the control group was 2,500. The classification result of suicidality, 255 (8.6%) students were low-risk group, 149 (4.8%) students were moderate-risk group and 60 (2.0%) students were high-risk group. In the suicide risk group, VRIN, F scale, Clinical scale and RC scales were significantly higher. In the control group L, K and S scales were significantly higher. Suicidality score has significant correlation with all RC scales. Conclusion : In the suicide risk group, overall psychopathology was higher than the control group. Taken together, features of depressive symptom, antisocial behavior, aggressiveness, introversion may indicate the risk of suicide in college students. These results display both clinical and public health implications for clinicians and school health professionals.
