Background: Long working hours are known to account for approximately one-third of the total expected work-related diseases, and much interest and research on long working hours have recently been conducted. Additionally, as the prevalence of prediabetes and the high-risk group for diabetes are increasing worldwide, interest in prediabetes is also rising. However, few studies have addressed the development of type 2 diabetes and long working hours in prediabetes. Therefore, the aim of this longitudinal study was to evaluate the relationship between long working hours and the development of diabetes in prediabetes. Methods: We included 14,258 prediabetes participants with hemoglobinA1c (HbA1c) level of 5.7 to 6.4 in the Kangbuk Samsung Cohort Study. According to a self-reported questionnaire, we evaluated weekly working hours, which were categorized into 35–40, 41–52, and > 52 hours. Development of diabetes was defined as an HbA1c level ≥ 6.5%. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the development of diabetes were estimated using Cox proportional hazards analyses with weekly working 35–40 hours as the reference. Results: During a median follow-up of 3.0 years, 776 participants developed diabetes (incidence density, 1.66 per 100 person-years). Multivariable-adjusted HRs of development of diabetes for weekly working > 52 hours compared with working 35–40 hours were 2.00 (95% CI: 1.50–2.67). In subgroup analyses by age (< 40 years old, ≥ 40 years old), sex (men, women), and household income (< 6 million KRW, ≥ 6 million KRW), consistent and significant positive associations were observed in all groups. Conclusions: In our large-scale longitudinal study, long working hours increases the risk of developing diabetes in prediabetes patients.
A Psychometric Evaluation of a Korean Version of the Quality of Life in Late-Stage Dementia Scale

Purpose: This study was conducted to translate and validate a Korean version of the Quality of Life in Late-Stage Dementia (QUALID-K) scale. Methods: A cross-sectional design was applied to culturally adapt and validate the scale. A total of 197 participants from two long-term care hospitals in Korea were recruited. The psychometric properties of the QUALID-K scale, including dimensionality of subscales, concurrent, discriminant, and convergence validity, test-retest reliability, inter-rater reliability, and internal consistency were evaluated. Results: The QUALID-K scale’s dimensionality differed from the original one-factor structure, and a three-factor model better fit the data. The validity analysis showed a significant association of the QUALID-K with cognitive function, activities of daily living, depressive symptoms, and pain. Test-retest and inter-rater analysis confirmed the measurement’s stability. Conclusion: The QUALID-K scale appears to be a reliable and valid measurement to assess the quality of life for those with severe dementia in the Korean population.
Three-Dimensional Reduced-Symmetry of Colloidal Plasmonic Nanoparticles
Jeong, Eunhye,Kim, Kihoon,Choi, Inhee,Jeong, Sunil,Park, Younggeun,Lee, Hyunjoo,Kim, Soo Hong,Lee, Luke P.,Choi, Yeonho,Kang, Taewook American Chemical Society 2012 NANO LETTERS Vol.12 No.5
<P>Owing to their novel optical properties, three-dimensional plasmonic nanostructures with reduced symmetry such as a nanocrescent and a nanocup have attracted considerable current interest in biophotonic imaging and sensing. However, their practical applications have been still limited since the colloidal synthesis of such structures that allows, in principle, for in vivo application and large-scale production has not been explored yet. To date, these structures have been fabricated only on two-dimensional substrates using micro/nanofabrication techniques. Here we demonstrate an innovative way of breaking symmetry of colloidal plasmonic nanoparticles. Our strategy exploits the direct overgrowth of Au on a hybrid colloidal dimer consisting of Au and polystyrene (PS) nanoparticles without the self-nucleation of Au in an aqueous solution. Upon the overgrowth reaction, the steric crowding of PS leads to morphological evolution of the Au part in the dimer ranging from half-shell, nanocrescent to nanoshell associated with the appearance of the second plasmon absorption band in near IR. Surface-enhanced Raman scattering signal is obtained directly from the symmetry-broken nanoparticles solution as an example showing the viability of the present approach. We believe our concept represents an important step toward a wide range of biophotonic applications for optical nanoplasmonics such as targeting, sensing/imaging, gene delivery, and optical gene regulations.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2012/nalefd.2012.12.issue-5/nl300435j/production/images/medium/nl-2012-00435j_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl300435j'>ACS Electronic Supporting Info</A></P>

The purpose of this study was to examine that multiple mediating effects of self-determination and selfefficacy in the relationship between the parental control and career maturity. In the study, 747 university students in Daegu, Busan and Seoul area were surveyed on their perceived level of parental control, career maturity, self-determination and self-efficacy. Data were analyzed using descriptive statistics, one-way ANOVA, and Pearson correlation analysis with SPSS 25.0 program, Hayes’Process Macro program and bootstrapping. The major results of this study were as follows; First, there were significant differences in college student’s career maturity by grade, major, experience in career-related services and part-time job experience period. Second, there were significant correlations between parental control(behavioral control and psychological control), career maturity, self-determination and self-efficacy. Third, self-determination and Self-efficacy had multiple mediating effects in the relationship between parental control and career maturity. In conclusion, this study found multiple mediating effects of self-determination and self-efficacy in the relationship between parental control(behavioral control and psychological control) and career maturity. It was also found that parental behavioral control had a positive effect on career maturity by increasing self-determination and self-efficacy while parental psychological control had a negative effect on career maturity by decreasing self-determination and self-efficacy.
