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).

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.

Journal of Korean Academic Society of Nursing Education 2015;21(4):490-498
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: 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.

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.

This study was done to evaluate the shear bond strength between light-cured glass ionomer cement (GIC) base and resin cement for luting indirect resin inlay and to observe bonding aspects which is produced at the interface between them by SEM. Two types of light cured GIC (Fuji II LC Improved, GC Co. Tokyo, Japan and Vitrebond(TM), 3M, Paul, Minnesota, U.S.A) were used in this study. For shear bond test, GIC specimens were made and immersed in 37degrees C distilled water for 1 hour, 24 hours, 1 week and 2 weeks. Eighty resin inlays were prepared with Artglass(R) (Heraeus Kultzer, Germany) and luted with Variolink(R) II (Ivoclar Vivadent, Liechtenstein). Shear bond strength of each specimen was measured and fractured surface were examined. Statistical analysis was done with one-way ANOVA. Twenty four extracted human third molars were selected and Class II cavities were prepared and GIC based at axiopulpal lineangle. The specimens were immersed in 37degrees C distilled water for 1 hour, 24 hours, 1 week and 2 weeks. And then the resin inlays were luted to prepared teeth. The specimens were sectioned vertically with low speed saw. The bonding aspect of the specimens were observed by SEM (JSM-5400(R), Jeol, Tokyo, Japan). There was no significant difference between the shear bond strength according to storage periods of light cured GIC base. And cohesive failure was mostly appeared in GIC. On scanning electron micrograph, about 30 - 120 microm of the gaps were observed on the interface between GIC base and dentin. No gaps were observed on the interface between GIC and resin inlay.

OBJECTIVE: This study aimed to analyze psychological characteristics of elderly patients. METHODS: The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) data of 110 elderly patients who visited the department of psychiatry was analyzed. We examined differences of MMPI-2 score according to sex and age. The elderly were classified into four clusters with similar characteristics. RESULTS: Depression, suicidal ideation, low motivation score was high in total sample. Depression, subjective depression, mental dullness, lassitude-malaise, psychasthenia, and fears score was higher among females than males. Through the cluster analysis, elderly were classified into four types of ‘high profile’, ‘1-2-7 profile’, ‘6-7-8-0 profile’, and ‘low profile’. CONCLUSION: The elderly patients who visited the department of psychiatry complain depression and helplessness. Females complained depression and anxiety more than males. Elderly were classified into four types of patients with high somatic complaints ‘high profile’, patients with high depression and helplessness ‘1-2-7 profile’, patients who were dissatisfied and could blame others ‘6-7-8-0 profile’, and patients who needed additional interview and projective test ‘low profile’.
