Authers analysed the electrocardiographic exercise test of 196 cases of normal and 150 cases of various diseases according to the Minnesota Code, Master's criteria and Lepeschkin's criteria and following results were obtained. 1. In normal cases, Lepeschkin's method of analysis of single Master's exercise test revealed less frequent false positive case (7.7%) than those of Master's (12.1%) and Minnesota Code (12.6%). 2. ST-segment changes by the Minnesota Code in the postexercise electrocardiogram were obtained 12.6% of nomal cases, 63.9% of the cases of anginal symptoms, 31.5% of hypertension and 15.4% of diabetes mellitus. 3. Positive exercise test by the Master's criteria in the postexercise electrocardiogram were obtained 12.1% of normal cases, 63.9% of the cases of anginal symptoms, 31.5% of hypertension and 15.4% of diabetes mellitus. 4. Positive exercise test by the Lepeschkin's criteria in the postexercise electorcardiogram were obtained 7.7% of normal cases, 50% of the cases of anginal symptoms, 18.4% of hypertension and 15.4% of diabetes mellitus.

PURPOSE: The purpose of this study is to identify factors that predict job satisfaction in office workers. Participants were recruited from eight industries in B Ku in D city, and the research was carried out from February 10 until October 10, 2014. Job satisfaction was assessed using the Minnesota Satisfaction Questionnaire (MSQ). METHODS: Data was analyzed using Pearson correlation coefficients and a stepwise multiple regression analysis with SPSS/WIN 18.0. There was a negative correlation between job satisfaction and job stress. RESULTS: Job stress (lack of reward, occupational climate, job demand, job insecurity) and psychological happiness were identified as determinants of job satisfaction, which explained 43.6% of the total variance of job satisfaction. CONCLUSION: The findings provide empirical evidence to help nurses prepare effective interventions related to the mental health promotion of office workers.

PURPOSE: This study aims to demonstrate whether the functionalities between the widely used questionnaire in other countries and the Korean-translated version show similarity. Also, it intends to verify their reliability and validity. METHODS: The original questionnaire was first developed by professor Noe at the University of Minnesota with 29 items named as “mentoring functions” to identify the participants' psychological and career-development functions. Using the Korean-translated version of the original questionnaire, the study was conducted on total 288 Kyung Hee University medical students, ranging from the first-year students to the third-year students on December 2015. In order to investigate if the survey form could be applied to the Korean participants, exploratory factor analysis and confirmatory factor analysis were conducted, using varimax rotation. Cronbach α statistics and the figures of standardized regression weights were analyzed respectively to indicate construct, convergent, and discriminant validities. RESULTS: The result of exploratory factor analysis shows there are a total of three functions, including the additional “friendship function” (Eigen value, 1.152; significant level if higher than 1.0) with its high emphasis. The result of confirmatory factor analysis also demonstrates the similarity (p=0.000). As the whole reliability scale of the three functions is significantly high (Cronbach α , 0.971), each reliability scales of the three functions are shown to be high (0.814-0.955) as well. CONCLUSION: The model, with its three functions, proved the significant statistics regarding the reliability and validity. According to this ground, the conclusion is that the adapted questionnaire used in this study could be applied to Korean medical students.

STATEMENTS OF PROBLEM: The fracture of acrylic resin dentures remains an unsolved problem. Therefore, many investigations have been performed and various approaches to strengthening acrylic resin, for example, the reinforcement of heat-cured acrylic resin using glass fibers, have been suggested over the years. Silane is important for bonding between glass fiber and resin. PURPOSE: The aim of the present study was to investigate the effect of various silane on the strength of PMMA resin and roughness of resin-glass fiber complex after abrasion test. MATERIAL AND METHODS: 3mm glass fiber (Chopped strand, Hankuk fiber Co., Milyang, Korea) was treated with 3 kinds of silane (MPS, EPS, APS) (Sila-ace, Chisso chemical, Tokyo, Japan) and mixed with PMMA resin(Vertex RS, Vertex Dental B.V., Zeist, Netherlands). Transverse strength and Young's modulus was measured using Instron (Instron model 4466, Instron, Massachusetts, USA). After abrasion test (The 858 Mini Bionix II Test System, MTS System Co., Minnesota, USA) surface roughness was evaluated using tester (Form Talysurf plus, Taylor Hopson Ltd., Leicester, England). Examination of scanning electron microscope was also performed RESULTS: Within this study, the following conclusions were drawn. 1. Surface treatment of glass fiber with MPS and APS increased transverse strength of PMMA resin complex, but surface treatment with EPS decreased transverse strength of PMMA resin complex (p<0.05). 2. Silane treated glass fiber increased Young's modulus of PMMA resin complex compared to desized glass fiber (p<0.05). 3. Roughness increased after abrasion test in case of PMMA resin reinforced with desized glass fiber (p<0.05). 4. Roughness change was not observed after abrasion test in case of PMMA resin reinforced with silane treated glass fiber (p>0.05).

Authors evaluated the electrocardiographic criteria of Minnesota Code (III-1, III-2) for the diagnosis of left and right ventricular hypertrophy in 93 cases of healthy peoples, 74 cases of left ventricular hypertrophy and 4 cases of right ventricular hypertrophy and following results were obtained. 1. By left ventricular hypertropy criteria (III-1), there were 5.4% of false positive and 14.9% of false negative cases. 2. By right ventricular hypertrophy criteria III-2), there were 24.7% of false positive and 20.0% of false negative cases. 3. Electrocardiographic diagnosis of ventricular hypertrophy by Minnesota Code (III-1, III-2) were more reliable criteria than many other criteria of ventricular hypertrophy.

PURPOSE: The patient-centered attitude is an effort to understand patients themselves as well as their disease. The doctor-oriented approach has been shifting to one where patients and participate in the deciding of medical service. We performed this study to investigate the patient-centeredness and influencing variables associated with personality traits. METHODS: We recruited 94 medical students before their psychiatric clinical clerkship, and all subjects were assessed by a structured questionnaire including socio-demographic data, Minnesota Multiphasic Personality Inventory(MMPI), Meyers-Briggs type indicator(MBTI), the patient-practitioner Orientation Scale(PPOS), and the Authoritarian Personality scale(AP), The AP and PPOS questionnaires were repeated after the psychiatric clinical clerkship. RESULTS: After the psychiatric clinical clerkship, the AP scores were significantly lower than before, and the PPOS significantly higher than before. The change in the AP scores were related to MBTI, correlated with MMPI subscales, however, inversely correlated with the changes in PPOS after the clinical clerkship. CONCLUSION: The authoritarian personality trait was related to, not only the personality trait including MBTI and MMPI subscales, but also to patient-centeredness in medical students.

OBJECTIVE: To investigate the relationship of job stress and scores on the Minnesota Multiphasic Personality Inventory (MMPI) clinical scales in firefighters. METHOD: A total of 648 firefighters from Daegu Metropolitan City were given 2 sets of questionnaires, the Korean Occupational Stress Scales (KOSS) and the MMPI. The results of 428 qualifying questionnaires were analyzed using ANOVA, correlation, and multiple regression. RESULTS: The study demonstrated that job stress differed by age, department, amount of exercise, and duty period. MMPI clinical scales differed by age, smoking, and amount of exercise. Job stress correlated with MMPI clinical scales and in particular with 2 MMPI clinical scales, -Depression and Social introversion-. In addition, job stress subscales were related. On multiple regression analysis, some MMPI clinical scales were affected by job stress subscales. CONCLUSION: This study suggests that job stress is associated with psychogenic factors in firefighters. The effective management for job stress might be helpful for the overall mental health of firefighters. Further study is required to determine which psychogenic factors are related to job stress.

OBJECTIVES: The aim of this study was to evaluate the psychological characteristics of the patients with bruxism by Minnesota Multiphase Personality Inventory(MMPI). METHODS: MMPI was administered to 87 patients(46 bruxism group and 41 control group) who had visited a local dental clinic from January to August 1998. RESULTS: The bruxism group had a higher score than control group in Masculinity-Femininity(Mf) scale. There were no differences between bruxism group and control group on the distribution of Depression(D), Psychopatic Deviate(Pd), Paranoia(Pa), Psychasthenia(Pt) scales. The bruxism group with the family history showed higher score than the bruxism group without family history in Pd scale. Male bruxism group had a higher score than female bruxism group in Defensiveness(K) scale and female bruxism group had higher score than male bruxism group in Pa scale. The bruxism group of clenching type had higher score than the bruxism group of mixed type in Social Introversion(Si) scale. There were no differences in MMPI score between those who had and did not have symptoms such as masticatory musle pain, neck pain and headache. CONCLUSION: It is concluded that individualized approach may be effective to the evaluation of psychological disturbances which might be related to sex, family history and, type of bruxism, while we did not find significant differences in personality charateristics between the bruxism and control groups.

PURPOSE: For evaluation of drug intoxication patients, the MMPI is a widely used neuropsychiatric tool to investigate patients' personalities. METHODS: We administered a questionnaire and the MMPI to patients who came to our ER between 1 March 2007 and March 1 2008. Patient characteristics, past neuropsychiatric history, and were investigated. RESULTS: We enrolled 43 patients, X females and Y males. Anti-psychotics were the drugs that were most frequently consumed (by 42% of subjects) and economic status was the most frequent cause of overdose. Pathologic psychosis was the most frequent disorder in their medical history. The MMPI indicated that depression type (D) was 64 and 36 patients were increased over the nomal level. 16 patients of 18 patients with depression history were increased in the type D (p=0.000) and assessment was analytically increased (k=0.854). CONCLUSION: MMPI of drug intoxication patients may be useful during early neuropsychiatric examinations, and may be a useful tool for making treatment decisions.
