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.

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.

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.

STATEMENT OF PROBLEM: The role of calcium sulfate in stimulating the growth of gingival soft tissue has been reported in few studies. Such a unique property of calcium sulfate could serve as a trouble-solving broker in compensating for the lack of soft tissues in various oral surgeries. PURPOSE: The purpose of this study was to compare the proliferating activities of human gingival fibroblasts seeded on various bone graft barrier materials of calcium sulfate, collagen, and polytetrafluorethylene (PTFE). MATERIAL AND METHODS: Two calcium sulfates (CAPSET(R) and CalForma(R), Lifecore Biomedical Inc., St. Paul, Minnesota, USA), a resorbable natural collagen (Bio-Gide(R), Geistlich Pharma Ag., Wolhusen, Switzerland), and a non-resorbable PTFE (TefGen-FD(R), Lifecore Biomedical Inc., St. Paul, Minnesota, USA) served as the human gingival fibroblasts'substrates and comprised the four experimental groups, whereas the untreated floors of culture plastics were used in the control group, in this study. Cells were trypsinized, seeded, and incubated for 48 h. The proliferating activities of fibroblasts were determined by XTT and SRB assay and absorbance (optical density, OD) was measured. One-way ANOVA was used to analyze the differences in the mean OD values between the groups of CAPSET, CalForma, Bio-Gide, TefGen, and the control (p<0.05). RESULTS: From the XTT assay, the mean OD value of the control group, the highest, was significantly greater than that of any of the four experimental groups followed by CalForma, CAPSET, TefGen, and Bio-Gide. Further, the mean OD value of CalForma, was significantly greater compared to that of Bio-Gide. From the SRB assay, Calforma showed the highest mean OD value, which was significantly greater than that of any other groups, followed by the control, CAPSET, Bio-Gide, and TefGen. The mean OD values of both the control and CAPSET were significantly greater compared to that of TefGen (p<0.05). CONCLUSION: Assessment of the viability and proliferation of cultured fibroblasts seeded and incubated for 48 h on various barrier-material substrates using XTT and SRB assay showed that calcium sulfate CalForma(R) promotes the proliferating activity of human gingival fibroblasts.

BACKGROUND: To evaluate serological typing of T(epidemiologic marker) and M protein(major virulence antigen) is important to understand pathogenesis and epidemiology of streptococcal infection. The purpose of this study is to find out whether there were major difference in distribution of serotypes isolated from healthy school children and patients with pharyngotonsillitis, and to characterize the geographical differences in distribution of the serotypes. METHOD: Twenty-three strains of group A streptococci were isolated from healthy school children in two different areas(Dongdaemun-Ku and Kangsuh-Ku) in Seoul in April and July 1996. 23 strains came from patients living in Dongjak-Ku with pharyngotonsillitis in April 1996. All isolated were serotyped by T agglutination, M precipitation and opacity factor at the WHO Collaborative Center for Reference and Research on Streptococci, University of Minnesota, Minneapolis. RESULTS: 89.1% of the strains were typable by T agglutination, 56.5% by M precipitation, and 52.2% were positive in opacity factor. T types 1, 25, 4, and 12 accounted for 65.2% of patients with pharyngotonsillitis, T types 12, and 25 accounted for 71.5% of healthy children in Dongdaemun-Ku, and T types 28, 6, and 3 accounted for 62.6% of healthy children in Kangsuh-Ku. T types 1, 25, 28, 12, 4 and M types 1, 75, 28, 4, 12 were typed in decreasing order. CONCLUSION: We characterized the differences in serotypes of group A streptocpcci between healthy children and patients. The periodic and seasonal serotyping analysis is important in monitoring and understanding of the epidemiologic patterns of group A streptococci.

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.
