  • Purpose: The purpose of this study was to test the reliability and validity of an MIL instrument for adolescents. Method: The research design was a three-phase, methodological study. 1) The original 46 items of the Meaning in Life (MIL) Scale were reviewed and corrected partially by 20 adolescents. 2) The content was validated by an expert panel (n=15) and adolescents (n=5). 3) The instrument was validated by survey (n=468). Finally, 33 items were chosen for the adolescents meaning in life(AMIL) scale. Results: Cronbach's alpha coefficient of the 33 items was .92, confirming the high internal consistency of the instrument. 2) Eight factors were extracted through factor analysis: 'experience of love', 'making efforts for goal', 'awareness of essential being', 'awareness of self limitation', 'feeling of satisfaction', 'relation experience', 'positive thinking', and 'hope'. These factors explained 58.26% of the total variance. Conclusion: AMIL Scale was identified as a tool with a high degree of reliability and validity. The tool can therefore be effectively utilized to assess the degree of meaning of life in caring areas for adolescents. Studies on AMIL of different adolescent subjects are needed for further verification.

  • This paper explores the relationship between network cooperation, innovation, internationalization and economic performance of manufacturing small and medium enterprises (SMEs) of engineering goods industry located in Bangalore city, India. At the outset, it is observed that SMEs receive the maximum assistance in the realm of product specifications. Moreover, they do not resort to manufacturing new products as much as they resort to product modifications or process improvements. Further, it is found (using Chi-square test of independence) that higher the network assistance received from an external network, greater is the innovation performance of SMEs. Subsequently, using analysis of variance (ANOVA), export intensity (proxy for internationalization performance) of SMEs is found to have a significant positive association with both the degree of their network cooperation and of their innovation performance. Lastly, it is observed that higher the degree of each of network cooperation, innovation performance and internationalization performance, better is the economic performance (measured by total sales turnover) of SMEs. These results have significant implications for the policy makers of the country to give due attention to network cooperation, innovation and internationalization as the means of enhancing the economic performance of SMEs.

  • Purpose: The purpose of this study is to explore the roles and function of family in mediating the relationship between depression and quality of life of patients with Parkinson's disease (PD). Most studies have found that depression is particularly common in patients with PD and further associated with poor quality of life. Family function, as a mediator, is based on a strength orientation perspective that emphasizes not only their responsibilities and risks but also recuperative powers and growth potential. Methods: Overall 157 adults with idiopathic Parkinson's disease were enrolled in this study via outpatient clinic and completed a set of assessment to measure depression using BDI, family APGAR questionnaire, and patients' quality of life using PDQ-8. Hierarchical multiple regression analysis was conducted to examine the mediating role of family APGAR score in the relationship between BDI and PDQ-8. Results: Patients' depression, gait disturbance, duration of illness, and family function were statistically significant on quality of life. These factors accounted for 60% of the variance in quality of life. Family function has a partial mediating effect on the relationship between depression and quality of life. Conclusion: Findings from the study suggest that although PD patients' depression impacts their quality of life, by having strong family function, the extent to which depression impacts the quality of life can be favorably mitigated. Additionally, these outcomes have important implications for future model development regarding PD patients.

  • Objectives: Previous in vitro studies determined the whitening effects of bleaching products on stained resin composite surfaces. This in vitro study aimed to verify the effectiveness of a whitening system on composite resin previously subjected to pigmentation, specifically examining the depth of whitening effectiveness within the material structure. Materials and Methods: A commercially available nano-filled composite resin was used. Specimens were stained using a coffee-based solution and a 10% carbamide peroxide-based gel was employed as the whitening agent. The pigment's penetration and the effect of the bleaching gel were evaluated by measuring color (CieLab values) from the outer edge to the inner part of the specimens. Color measurements were taken at 14 points, starting from 0.1 mm from the external perimeter up to 3.0 mm. Results: Analysis of variance tests showed a statistically significant difference between the Control Group (CG), Pigmentation Group, and Whitening Group. The whitening agent was effective up to 1.5 mm in depth, with Whiteness index (W) values not statistically different from those of CG up to 0.5 mm in depth. Conclusions: Whitening agents on nano-filled resin composite previously pigmented appear effective in restoring the W to values similar to the original, particularly in the superficial layers of the sample.

  • Purpose: The purpose of the study was to examine the relationships among pain belief, perceived social support, coping strategies, and quality of life of people with noncongenital spinal cord injury and to identify factors influencing quality of life. Methods: A correlational predictive design was used. The data were collected from 197 people with noncongenital spinal cord injury with questionnaires in 2012 in Korea. The data were analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using SPSS/WIN 18.0. Results: Pain belief, perceived social support, and coping strategies were correlated significantly with the quality of life. As a result of stepwise multiple regression analysis, pain belief, perceived social support, coping strategies, damaged area, and time since injury were discovered to account for 59.1% variance of the quality of life. The variable that most affected the quality of life was pain belief followed by perceived social support and coping strategies. Conclusion: The results of the study clearly demonstrate the importance of pain control, social support, and coping skills in order to improve quality of life among people with noncongenital spinal cord injury.

  • Purpose: The purpose of this study was to investigate the Quality of Life (QOL) and related factors in the patients with dizziness. Methods: The data were collected between March and June 2008 for 200 individuals who agreed to participate in the study. Uncertainty (Uncertainty in illness scale), anxiety, depression (Hospital anxiety & depression scale) and Vestibular disability activities of daily living (Vestibular disability-activities of daily living [ADL] scale) as well as QOL (Dizziness Handicap Inventory) were measured. Results: The mean QOL score was 37.5 (${\pm}23.0$). Monthly income, etiology of, frequency of, and total duration of dizziness were the significant factors related to QOL in these patients. Having had a fall, anxiety, depression, uncertainty and vestibular disability in daily living were also significant factors influencing QOL. In multiple regression analysis, anxiety, vestibular disability-ADL, falls, total duration of symptoms, uncertainty, and etiology of dizziness explained 41% of variance of QOL. Conclusion: The level of QOL in our patients was moderate as compared to those in previous studies. Anxiety and vestibular disability were the most important factors predicting low QOL. Use of nursing intervention programs designed to relieve these factors should also result in improving the QOL in the patients with dizziness.

  • The aim of the present study was to measure intra-individual consistency in clothing and fabric evaluation and to examine its relation to the ratings. A sample of 93 female and 97 male university students rated clothing of 4 styles of daytime wear and 2 fabrics on 15 pairs of polar adjectives twice in 7-days interval. Correlation coefficients between the two ratings for each subject, intra-individual consistency in the evaluation, ranged from -0.12 to 0.89 and mean coefficient was 0.63 of female and -0.01 to 0.78 and mean coefficient was 0.54 of male. Based on the coefficients, the subjects were classified into three groups: high, medium, and low intra-individual consistency. Analysis of variance of mean ratings by the three groups revealed that significant difference existed in 24% of female and 23% of male in 90 combinations of 6 clothing and 15 semantic differential scales. Female of subjects with high intra-individual consistency were most likely definite to evaluate clothing, whereas the ones with low were least. But male subjects were not definite. Mean correlation coefficients for style evaluation subscales of female was 0.39, but male was 0.44. Among the semantic differential scales, high stability in the two ratings was observed for the synthetic clothing evaluation. Correlation coefficients for each clothing obtained from the mean score of the subjects in each semantics differential scale were around 0.98, including that the mean scores of the subjects in each scale could yield excellent stability in clothing evaluation.

  • Purpose: The purposes of this study were to describe the pattern of type D personality, to compare the life style and quality of life between type D personality and non-type D personality patients, and to investigate the factors influencing quality of life in patients with hypertension. Methods: A cross sectional, descriptive study was used. The participants in this study were 193 outpatients who were diagnosed with hypertension at two university hospitals in urban area, Korea. The data was collected from December, 2006 to January, 2007. Type D personality was measured by the DS-14 scale. Results: The prevalence of type D personality was 83.9%. Patients of type D personality were significantly different in educational status, monthly income, fat intake and exercise, and had a lower overall quality of life than patients of non-type D personality. Under controlled general characteristics and life style factors, multiple linear regression analysis was performed. The most significant factor influencing quality of life in hypertensive patients was type D personality, and this factor explained their quality of life with a variance of 14.8%. Conclusions: Various programs for psychological intervention are required to control for the distressed personality of patients with hypertension. Further studies should be conducted prospectively on a larger patient population.
