This study did a comparative analysis on the patterns of several male bodice slopers, followed by evaluating the appearance through a virtual garment simulation, which used a three-dimensional virtual garment system. Through this process, this study attempted to comparatively analyze the suitability of the garment or each sloper according to body parts. The analysis of the drawing formulas of bodices slopers had the following results. With a standard chest size, all six slopers had a 1:4 ratio for a front and back chest size; 1:5 or 1:6 for a front and back breast size 1:5 or 1:4 for a neck base circumference; and 1:20 or 1:12 for the chest size. When comparing the anthropometric figures and the actual measurements of each body part for the bodice slopers, the actual measurements secured extra amounts in the drawing process. The evaluation results for appearance of the six men's bodice slopers showed that the slopers used by companies (E and F) had top scores followed by the slopers made for (C and D), while the sloper for education (A) received the lowest scores. Regarding the results of the variance analysis verifying the significant difference between the slopers, twenty-five items had significant differences with the exception of four items on the front side and one item on the backside.

Argonne National Laboratory of the United States and Kharkov Institute of Physics and Technology (KIPT) of Ukraine have cooperated on the development, design, and construction of a neutron source facility. The facility was constructed at Kharkov, Ukraine, and its commissioning process is underway. The facility will be used for researches, producing medical isotopes, and training young nuclear specialists. The neutron source facility is designed with a provision to include a cryogenically cooled moderator system-a cold neutron source (CNS). This CNS provides low-energy neutrons, which will be used in the scattering experiment and material structures analysis. Cold neutron guides, coated with reflective material for the low-energy neutrons, will be used to transport the cold neutrons to the experimental site. The cold neutron guides would keep the cold neutrons within certain energy and angular space concentrated inside, while most of the gamma rays and high-energy neutrons are not affected by the cold neutron guides. For the KIPT design, the cold neutron guides need to extend several meters outside the main shield of the facility, and curved guides will also be used to remove the gamma and high-energy neutron. The neutron guides should be installed inside a shield structure to ensure an acceptable biological dose in the facility hall. Heavy concrete is the selected shielding material because of its acceptable performance and cost. Shield design analysis was carried out for the CNS guide hall. MCNPX was used as the major computation tool for the design analysis, with neutron and gamma dose calculated separately. Weight windows variance reduction technique was also used in the shield design. The goal of the shield design is to keep the total radiation dose below the $5.0{\mu}Sv/hr$ guideline outside the shield boundary. After a series of iterative MCNPX calculations, the shield configuration and parameters of CNS guide hall were determined and presented in this article.

Purpose: This study aimed to analyze deformation according to post-curing of complete arch artificial teeth for temporary dentures printed with a digital light processing (DLP) printer. Methods: An edentulous model was prepared and an occlusal rim was produced. The edentulous model and occlusal rim were scanned using a model scanner. A complete denture was designed using a dental computer-aided design, and the denture base and artificial tooth were separated. Ten complete arch artificial teeth were printed using a 3D printer (DLP). Complete arch artificial teeth was classified into the following three groups: a group no post-curing (NC), a group with 10 minutes post-curing (10M), and a group with 20 minutes post-curing (20M). Specimens were scanned using a model scanner. The scanned data were overlapped with the reference data. Statistical analysis was performed using one-way ANOVA analysis of variance, Kruskal-Wallis test, and Mann-Whitney U test (α=0.05). Results: Regarding the overall deviation of complete arch artificial teeth, the NC group showed the lowest mean deviation of 111.13 ㎛ and the 20M group showed the highest mean deviation of 131.03 ㎛. There were statistically significant differences among the three groups (p<0.05). Conclusion: The complete arch artificial tooth showed deformation due to post-curing. In addition, the largest shrinkage deformation was observed at 10 minutes of post-curing, whereas the least deformation was observed at 20 minutes.

This study was conducted to identify the factors affecting Korean spirituality. This study used secondary data analysis of data collected during the validation phase of the New Version of Spirituality Assessment Scale. The participants of the raw data were Korean adults aged 19 and older, with a balanced sampling across different age groups. The collected data was analyzed using Person's correlation coefficient to identify the relationship between spirituality and psychological characteristics (self-esteem, depression, loneliness), and stepwise multiple regression to identify factors influencing spirituality. The results indicated that higher spirituality in Koreans is associated with higher self-esteem, and lower loneliness. Spirituality in Koreans was influenced by religious characteristics, self-esteem, loneliness, and gender. These variables explained 62.3% of the variance in spirituality. Based on the finding that spirituality in Koreans is influenced by religious and psychological characteristics, we suggest to develop spiritual health of intervention programs that consider both psychological and religious characteristics.

Objectives There is a controversy regarding the construct validity of anxiety and depression. Some believe that these two symptoms are basically the same construct, that is, both measure what is called 'general distress' or two phenomena are distinct experiences which often coexist. To further understand relationship between anxiety and depressive symptoms, we investigated the factor structure of a combined anxiety and depression scale among psychiatric outpatients. Methods Data of Zung's Self-Rating Depression and Anxiety Scales were gathered from 401 newly visiting psychiatric outpatients at a university-affiliated hospital. We performed a component analysis on the 40 items from two scales. Results Exploratory factor analysis revealed a seven factor structure explaining 56% of total variance. Overall finding indicated that depression and anxiety scales consisted of four symptom domains : mainly depressive symptoms, mainly anxiety symptoms, common somatic symptoms, and others. Conclusions Our results suggest that the construct of self-reported depressive and anxiety symptoms are more complex than previously thought, i.e., either one or two factor theories. These findings also support that anxiety and depression can be better modeled by dimensional approach. Clinicians may be alert for the fact that both depression and anxiety scales measure distinct and also common aspects. Further researches on other scales especially, interview based instruments are needed.

Purpose: To report the use of multiband accelerated echo-planar imaging (EPI) for resting-state functional MRI (rs-fMRI) to achieve rapid high temporal resolution at 3T compared to conventional EPI. Materials and Methods: rs-fMRI data were acquired from 20 healthy right-handed volunteers by using three methods: conventional single-band gradient-echo EPI acquisition (Data 1), multiband gradient-echo EPI acquisition with 240 volumes (Data 2) and 480 volumes (Data 3). Temporal signal-to-noise ratio (tSNR) maps were obtained by dividing the mean of the time course of each voxel by its temporal standard deviation. The resting-state sensorimotor network (SMN) and default mode network (DMN) were estimated using independent component analysis (ICA) and a seed-based method. One-way analysis of variance (ANOVA) was performed between the tSNR map, SMN, and DMN from the three data sets for between-group analysis. P < 0.05 with a family-wise error (FWE) correction for multiple comparisons was considered statistically significant. Results: One-way ANOVA and post-hoc two-sample t-tests showed that the tSNR was higher in Data 1 than Data 2 and 3 in white matter structures such as the striatum and medial and superior longitudinal fasciculus. One-way ANOVA revealed no differences in SMN or DMN across the three data sets. Conclusion: Within the adapted metrics estimated under specific imaging conditions employed in this study, multiband accelerated EPI, which substantially reduced scan times, provides the same quality image of functional connectivity as rs-fMRI by using conventional EPI at 3T. Under employed imaging conditions, this technique shows strong potential for clinical acceptance and translation of rs-fMRI protocols with potential advantages in spatial and/or temporal resolution. However, further study is warranted to evaluate whether the current findings can be generalized in diverse settings.

Background: There are various patient and professional factors responsible for the delay in start of treatment (SOT) for head and neck cancers (HNC). Materials and Methods: This retrospective study was conducted on data for HNC patients registered at the hospital cancer registry in North-East India. All cases diagnosed during the period of January 2010 to December 2012 were considered for the present analysis. Educational levels of all patients were clustered into 3 groups; illiterates (unable to read or write), qualified (school or high school level education), and highly qualified (college and above). Results: In the present analysis 1066 (34.6%) patients were illiterates, 1,869 (60.6%) patients were literates and 145 (4.7%) of all patients with HNC were highly qualified. The stage at diagnosis were stage I, seen in 62 (34.6%), stage II in 393 (12.8%), stage III in 1,371 (44.5%) and stage IV in 1,254 (40.7%). The median time (MT) to the SOT from date of attending cancer hospital (DOACH) was, in illiterate group MT was 18 days, whereas in the qualified group of patients it was 15 days and in the highly qualified group was 10 days. Analysis of variance showed there was a significant difference on the mean time for the delay in SOT from DOACH for different educational levels (F=9.923, p=0.000). Conclusions: Educational level is a patient related factor in the delays for the SOT in HNCs in our population.

This study was designed to verify the influence of mothers on their young adults in pro-environmental consuming consciousness and behavior. The compiled data are based on the responses of questionnaires from 278 young adults who reside in Seoul, Korea. The data were analyzed by frequency, standard deviation, mean, unitary dispersion, rank revolution analysis, analysis of variance (ANOVA), and multiple regression analysis by SPSS 14.0K for Windows. This study has discovered the following: First. A mother's pro-environmental consuming behavior is one of the most important factors significantly influencing a young adult's consciousness and behavior. Second. A friendly and positive consciousness about the environment enhances pro-environmental consuming behavior. A close inter-relationship exists between consciousness and behavior. However, some significant discrepancy was found between pro-environmental consuming consciousness and pro-environmental consuming behavior; that is, the level of pro-environmental consciousness was higher than the level of pro-environmental behavior. Third. Sensitivity to environmental information influenced pro-environmental consumption consciousness and behavior. Female students are more concerned about and sensitive to environmental matters than are male students. Fourth. Among the subordinate dependent variables, recycling behavior is most influenced by independent variables. Among the pro-environmental consuming behavior sector, a mother's disposal behavior exerts the most influence on the young adult's behavior. In the results of this study, it is pointed out that it is absolutely necessary fur young adults to bring up their practice level of pro-environmental purchase and consuming behaviors, and it is advised that appropriate and relevant education programs should be developed.

In this study, we tested the reliability and validity of the Korean Version of nonattachment scale(K-NAS) that Sahdra et al., had developed to measure for nonattachment. In result, the internal consistency coefficient(Cronbach's alpha) of the K-NAS was (.94) high, correlation coefficients of item-total were to .32 from .69. The result of factor analysis showed that single factor accounted for 37.77 % of the total variance. Confirmatory factor analysis and additional exploratory factor analysis demonstrated that the 1 factor model was satisfactory. K-NAS was positively related to experiences scale, self-compassion, psychological well-being and mindfulness, and negatively related to depression. These findings suggest that the Korean Version of Nonattachment Scale(K-NAS) was reliable and valid scale to measure for nonattachment. Finally, The implication of this study and direction for future study were discussed.
