  • This research examines the effects of consumers' moderation and simplicity, autonomy, and income level on happiness, and based on this, classifies consumer types and examines the differences in consumer happiness and life happiness in accordance with this classification. The questionnaire survey was conducted on adults in their 20's through 60's. Moreover, hierarchical regression analysis, cluster analysis, and the analysis of variance were conducted. The results of this research are as follows. First, on consumer happiness, moderation and simplicity, income level, autonomy, education level, and gender had significant effects; on life happiness, moderation and simplicity, income level, autonomy, and education level had significant effects. Second, consumers were classified into three types according to moderation and simplicity, autonomy, and income level, and when making a comparison based on these factors between consumer happiness and life happiness, both consumer happiness and life happiness showed significant differences, but the detailed aspects were different. In the case of consumer happiness, non-autonomous moderation and simplicity type were reported to have the highest sense of happiness, followed by autonomous moderation and simplicity type, and passive moderation and simplicity type, but in the case of life happiness, autonomous moderation and simplicity type were reported to have the highest sense of happiness, followed by non-autonomous moderation and simplicity type, and passive moderation and simplicity type.

  • Background: Many studies have explained regional disparities in health by socioeconomic status and healthcare resources, focusing on differences between urban and rural area. However some cities in Korea have the highest cardiovascular mortality, even though they have sufficient healthcare resources. So this study aims to confirm three hypotheses. (1) There are also regional health disparities between cities not only between urban and rural area. (2) It has different regional risk factors affecting cardiovascular mortality whether it is urban or rural area. (3) Besides socioeconomic and healthcare resources factors, there are remnant factors that affect regional cardiovascular mortality such as health behavior and physical environment. Methods: The subject of this study is 227 local authorities (si, gun, and gu). They were categorized into city (gu and si consisting of urban area) and non-city (gun consisting of rural area), and the city group was subdivided into 3 parts to reflect relative different city status: city 1 (Seoul, Gyeonggi cities), city 2 (Gwangyeoksi cities), and city 3 (other cities). We compared their mortalities among four groups by using analysis of variance analysis. And we explored what had contributed to it in whole authorities, city and non-city group by using multiple regression analysis. Results: Cardiovascular mortality is highest in city 2 group, lowest in city 1 group and middle in non-city group. Socioeconomic status and current smoking significantly increase mortality regardless of group. Other than those things, in city, there are some factors associated with cardiovascular mortality: walking practice(-), weight control attempt(-), deficiency of sports facilities(+), and high rate of factory lot(+). In non-city, there are other factors different from those of city: obesity prevalence(+), self-perceiving obesity(-), number of public health institutions(-), and road ratio(-). Conclusion: To reduce cardiovascular mortality and it's regional disparities, we need to consider differentiated approach, respecting regional character and different risk factors. Also, it is crucial to strengthen local government's capacity for practicing community health policy.

  • Purpose: This study was conducted to test whether Health Communication Assessment Tool (HCAT) developed by Campbell et al. in 2013 can be applied to assess Korean nursing students' communication skills in simulation education. Methods: The content validity of the Korean version of HCAT (K-HCAT) was evaluated through expert's assessment and a principal component analysis was conducted for testing construct validity. The convergent validity was tested by measuring relationship between the K-HCAT and those of existing communication assessment tool for standardized patient instruction. The evaluation was done by surveying 154 senior students from four different nursing colleges. Results: The K-HCAT was condensed into 15 items from the original 22 HCAT items. Four factors were extracted from the principal component analysis; factor loadings ranged from .50 to .83; cumulative explained variance was 62.65%. Four factors were entitled as 'relationship building', 'empowering', 'empathy/response', and 'education/feedback'. Cronbach's ${\alpha}$ for sub-dimensions ranged from .73 to .84. An evaluation of convergent validity showed that the scores of the K-HCAT were moderately correlated with those of an assessment tool for standardized patient instruction. Conclusion: The K-HCAT can be used as an effective tool for assessing nursing students' communication skills in various kinds of simulation educations Further research is needed to test the consistency of the K-HCAT.

  • Purpose: This study was conducted to examine differences in Spiritual Interests Related to Illness Tool (SpIRIT) scores and the degree of spiritual needs (SNs) between patients with terminal cancer and their primary family caregivers and to compare spiritual needs between them. Methods: The study participants were inpatients with terminal cancer and their primary family caregivers at 40 national hospice centers. The final analysis included 120 SpIRIT surveys from patients and 115 from family members, and 99 SNs questionnaires from patients and 111 from family members. Data analysis was conducted using descriptive statistics, the t-test, one-way analysis of variance, and Pearson correlation coefficients. Results: There were no significant between-group differences in SpIRIT scores or SNs. The SpIRIT sub-dimensions that ranked high for both patients and primary family caregivers were "maintaining positive perspective", "loving others", and "finding meaning". The SNs sub-dimensions were ranked identically in both groups, in the order of "love and connection", "hope and peace", "meaning and purpose", respectively. In both groups, the recognition of the importance of spiritual matters and religion were major factors influencing SpIRIT scores and SNs. Conclusion: The SpIRIT scores and degree of SNs of patients with terminal cancer and their primary family caregivers were found to be very closely related, and the needs for coherence and meaning were greater than religious needs. When providing spiritual care for patients with terminal illness, family members should also be considered, and their prioritization of spiritual needs and the importance of spiritual matters and religion shall be taken into account.

  • The Down-the-Hole hammer is one of the pneumatic drill equipment used for grinding, drilling, and mining. One the advantages of which is that a reduction work efficiency at deep site are relatively small compared to other drilling methods. Due to the large vibration in the underground area, it is difficult to measure the performance of the hammer, and hammer testing requires substantial production cost and operating expenses so research on the development of the hammer is insufficient. Therefore, this study has developed a dynamic simulation model that apprehends the operating principles of an 8-inch DTH hammer and calculates performance data such as performance impact force, piston speed, and BPM. By using the simulation model, design factors related to strike force and BPM were selected, and the influence of each design factors on performance was analyzed through ANOVA analysis. As a result, be the most important for BPM and the strike force are position of upper port that push the piston in the direction of the bit and in BPM, the size of the empty space between the bits and the piston is the second most important design factor.

  • Online recommendation services help people search for an appropriate product among a huge assortment in stores that also minimize consumers' choice overload. People with a need for uniqueness are likely to prefer this online recommendation service based on individual needs and tastes. This study verifies the effect of consumers' choice overload and similarity avoidance in consumers' evaluation towards an online recommendation service with a focus on innovativeness and use comparability. Two-hundred consumers participated in this study and data were collected through an online survey firm. A mock retailer's webpage was created and showed six types of sneakers, which was presented as a result of product recommendation based on consumers' personal information. Data was analyzed using confirmatory factor analysis (CFA), analysis of variance (ANOVA), and regression analysis. The results show that people with a high similarity avoidance perceive an online recommendation service as an innovative and compatible service. They also perceive a high level of use compatibility for an online recommendation service, especially when it is difficult to choose a product under choice overload. Innovativeness and use compatibility of an online recommendation service increase behavioral intention. The results of this study can contribute to strategies to start online recommendation services from online retailers' websites that identify circumstances in which consumers can adopt innovative services in a positive manner.

  • Objective: The aim of this study was to investigate the differences in spatiotemporal gait performance, function, and pain of lower-extremity according to foot morphological characteristics. Method: This case-control study recruited 42 adults and they were classified into 3 groups according to foot morphology using navicular-drop test: pronated (≥ 10 mm), normal (5~9 mm), and supinated (≤ 4 mm) feet. Spatiotemporal gait analysis and questionnaires including Foot and Ankle Ability Measure activities of daily living / Sports, Western Ontario and McMasters Universities Osteoarthritis Index, Lower Extremity Functional Scale, International Physical Activity Questionnaire, and Tegner activity score were conducted. One-way analysis of variance was used for statistical analysis. Results: The pronated feet group showed longer loading response and double limb support in both feet and increased pre-swing phase in non-dominant feet. The supinated feet group demonstrated a longer swing phase in non-dominant feet and single limb support in dominant feet. However, there was no significant group difference in function and pain of knee joint and lower-extremity between groups. Conclusion: Our results indicated that abnormal spatiotemporal gait performance according to foot morphology. Although there was no difference in lower extremity dysfunction and pain according to the difference in foot morphology, they have the possibility of symptom occurs as a result of continuous participation in activities of daily living and sports. Therefore, individuals with pronated or supinated foot should be supplemented by utilizing an orthosis or training to restore normal gait performance.

  • In this work, a novel reliability approach for combined high and low cycle fatigue (CCF) estimation is developed by combining active learning strategy with least squares support vector machines (LS-SVM) (named as ALS-SVM) surrogate model to address the multi-resources uncertainties, including working loads, material properties and model itself. Initially, a new active learner function combining LS-SVM approach with Monte Carlo simulation (MCS) is presented to improve computational efficiency with fewer calls to the performance function. To consider the uncertainty of surrogate model at candidate sample points, the learning function employs k-fold cross validation method and introduces the predicted variance to sequentially select sampling. Following that, low cycle fatigue (LCF) loads and high cycle fatigue (HCF) loads are firstly estimated based on the training samples extracted from finite element (FE) simulations, and their simulated responses together with the sample points of model parameters in Coffin-Manson formula are selected as the MC samples to establish ALS-SVM model. In this analysis, the MC samples are substituted to predict the CCF reliability of turbine blades by using the built ALS-SVM model. Through the comparison of the two approaches, it is indicated that the reliability model by linear cumulative damage rule provides a non-conservative result compared with that by the proposed one. In addition, the results demonstrate that ALS-SVM is an effective analysis method holding high computational efficiency with small training samples to gain accurate fatigue reliability.
