  • Objectives : Behavioral and psychological symptoms of dementia(BPSD) represent significant clinical problems, resulting in functional decline, caregiver distress, institutionalization and increased mortality. A recent study showed gender differences have important role in the development of BPSD, but relationship between BPSD and gender has never been studied in Korea. This study was designed to examine whether patients with Alzheimer's disease show gender differences in behavioral and psychological symptoms of dementia(BPSD). Methods : Ninety-eight subjects with Alzheimer's disease were included in this study. We carried out history taking and cognitive assessment for the diagnosis of Alzheimer's disease based on DSM-IV. Cognitive impairment and BPSD were measured using the Mini Mental State Examination(MMSE), Global Deterioration Scale (GDS), Clinical Dementia Rating(CDR) and the Korean Neuropsychiatric Inventory(K-NPI). Independent samples t-test was used to examine the differences across gender in BPSD. Correlation analysis between MMSE, CDR, GDS and NPI was performed using Pearson's correlation coefficient. Results : There were no significant gender differences between the gender in BPSD. We found statistically significant negative correlations between MMSE with NPI total score, and with scores of several sub-domains such as hallucination. Conclusions : This study showed that gender differences in BPSD are not significant. Further research is necessary to identify whether BPSD affect gender differences or individual differences.

  • This study was undertaken to investigate the factors that influence post-traumatic growth in patients with breast cancer. The study subjects were 100 outpatients with breast cancer who visited the outpatient clinic of a university hospital. The instruments used for this study were Korean Post-traumatic Inventory (K-PTGI), Modified Medical Outcomes Study Social Support Survey (mMOS-SS), Self-Efficacy Scale for Self-Management of Breast Cancer (SESSM-B) and Cancer Coping Questionnaire (CCQ). The data were analyzed by t-test, ANOVA, Pearson-correlation coefficient, and stepwise multiple regression using SPSS/WIN 21.0. The mean score of post-traumatic growth was $3.4{\pm}0.9$ out of 5. Post traumatic growth had statistically significant correlation with social support, breast cancer self-management self-efficacy, and coping behavior. In stepwise multiple regression analysis, post-traumatic growth was significantly influenced by therapeutic compliance related self-efficacy and positive reframing coping behavior and it was account for 29% of the total variance. These results suggest that these influencing factors should be considered in developing the nursing intervention to improve the post-traumatic growth in patient with breast cancer.

  • The purpose of this study was to explore factors associated with smartphone dependence among adults in their 20s. The data were derived from the 2017 Survey on Smartphone Over-dependence conducted by the Ministry of Science and ICT and the National Information Society Agency. There were 3,684 participants. The data were analyzed by frequency, percentage, mean, standard deviation, independent t-test, Pearson's correlation coefficient, and weighted hierarchical multiple regression analysis. For the results, factors related with higher smartphone dependence of participants were duration (β=.18, p=.000) and frequency (β=.04, p=.000) of usage, gaming (β=.15, p=.000), watching videos (β=.09, p=.000), mobile shopping (β=.05, p=.000), working (β=.05, p=.010), e-mailing (β=.13, p=.000), and sports betting (β=.07, p=.000). Music (β=-.07, p=.000) and adult content (β=-.07, p=.000) significantly reduced their smartphone dependence. SNS (Social Networking Services) (β=.01, p=.358) and instant messengers (β=-.02, p=.330) were not factors related to smartphone dependence. However, instant messengers were the most used by participants and had a strong correlation with working (r=.55, p=.000). This study shows that smartphone usage patterns related with smartphone dependence among adults in their 20s are different from those of children and adolescents. These results could be used to more deeply understand smartphone dependence among adults in their 20s and plan early detection and prevention and care of dependence.

  • The purpose of this descriptive survey was to investigate the duration of exclusive breastfeeding practice and its related factors of married immigrant Vietnamese women. And to provide baseline information necessary to develop education programs for the promotion of exclusive breastfeeding practice among them. 125 married immigrant Vietnamese women with a child between 6 months and 60 months old were conveniently recruited in two Multi-cultural Family Support Center in Chungcheong area. Data were collected through interviews using a structured questionnaire of Korean and Vietnamese versions. The data were analyzed using frequencies, t-test, ANOVA, Stepwise multiple regression with SPSS 18.0 program. The results were as follows; 1) The mean duration of exclusive breastfeeding of the subjects was 15.9 weeks. 2) As the infants grows older, the rate of formula feeding and mixed feeding were markedly increased. 3) Stepwise multiple regression analysis indicated that breastfeeding education and family type were significant determinants of the duration of exclusive breastfeeding practice. This model accounted for 30.8% of the duration of exclusive breastfeeding practice. Based on these results, we recommend to develop systematic breastfeeding education program in order to promote the duration of exclusive breastfeeding practice among married immigrant Vietnamese women.

  • Purpose - This study aimed to (a) investigate the effects of emotional intelligence on customer orientation, (b) examine the impact of customer orientation on customer relationship management (CRM) performance (including CRM-related variables such as 'relationship commitment,' 'image of corporation,' and 'customer loyalty'), and (c) identify the conceptual framework of emotional intelligence. Research design, data, and methodology - The data were collected using a questionnaire given to a sample of employees of luxury hotels in the metropolitan area. To test the hypotheses, AMOS were conducted for the 271 respondents of the sample using the SPSS Win 17.0 software. The concept of emotional intelligence (EI) has been on the radar of many leaders and managers over the past few decades. Emotional intelligence is generally accepted to be a combination of emotional and interpersonal competencies that influence behavior, thoughts, and interactions with others. Emotional intelligence consists of four factors: understanding the self's emotion, understanding other people's emotions, emotion utilization, and emotion control. Understanding the self's emotion means to understand of my own emotions. Understanding other people's emotions is to understand of the emotions of the people around me and to know how my friends feel based on their behavior. The concept of emotion utilization means to set goals for myself and then try to achieve them, encouraging myself to do my best. The concept of emotion control means I can control my temper, handle difficult situations rationally, and calm down quickly when I am very angry. Results - As a result of the analysis, three factors (understanding the self's emotion, understanding of other people's emotions, and emotion utilization) were shown to have a significant effect on customer orientation. Emotion control had an insignificant effect on customer orientation. Only emotion control makes it difficult to solve customers' problems because it is a passive behavior. In order to solve the customers' problems, hotel employees have to show a positive attitude. Second, customer orientation had a significant effect on customer relationship management performance (customer relationship commitment, corporate image, and customer loyalty). In other words, customer orientation increases commitment to customer relationships. For example, employees who have a customer-orientated perspective provide good service to their customers, while employees who don't have a customer-orientated perspective can't satisfy their customers. Customer orientation can also generate a good image among customers, because they evaluate the image of a hotel through the behavior of hotel employees. So it is very important for employees to show excellent customer orientation. Conclusions - It is very important for hotel CEOs to manage their employees' emotional intelligence. In order to increase their employees' emotional intelligence abilities, CEOs have to manage the overall corporate culture and reward programs to achieve what they want. This is because the system can lead to a customer-orientated mind-set and CRM performance among employees. As a result, the hotel CEO has to pay attention to the emotional intelligence of employees to achieve strong CRM performance. The sentence as originally written was a bit unclear. If this edit does not retain your intended meaning please consider: "Only emotion control does not have a significant impact on customer orientation, and therefore on the ability of an employee to solve customer problems, because it is a passive behavior." Please use the version of the sentence that best captures your original meaning.

  • Purpose - The Korean child welfare services may have different feelings between providers and users. Few studies on the child welfare service quality have been conducted and research on the coorientation model of child welfare services are nonexistent. We compared the perceptions of Korean child welfare service providers and users in this study. It will have many applications in the service quality fields by applying a coorientation model. Research design, data, and methodology - In order to enhance user satisfaction with child welfare services, around 200 samples were carried out both in Busan and Kyungsangnamdo randomly. Seven point Likert scale was used in the questionnaire. Two measurements were made to evaluate the different positions on the part of child welfare service providers and users to assess their mutual orientation. Paired t-test verification was conducted for congruency analysis, and the verification of agreement and accuracy was analyzed by independent t-tests. Results - We empirically examined the differences between the providers and the users stance. The results are as follows. We have verified the statistical significance of the difference in perception between providers and users. We also confirmed a degree of agreement, a degree of congruency, a degree of accuracy and a degree of meta agreement in the study. In the Korean child welfare service quality, the coorientation model of process quality appeared in the form of semi-dissensus, the coorientation model of results quality were shown in the form of ignorances and the coorientation model of physical environment quality were investigated in the form of semi-dissensus. Conclusion - The study concluded that users need to understand more about the providers in order to enhance the coorientation model in process quality and physical environmental quality, and the providers need to persuade the users clearly about the positive factors. To enhance the coorientation model of the result quality, it can be misunderstood by guessing that the other party will positively evaluate it. Therefore, users believe that they need to talk more clearly to the provider about the results of the korean child welfare service quality to reduce misunderstandings and to understand each other about the resulting quality.

  • This study examined the factors influencingthe adaptation to university life of nursing students. Data were collected from 235 nursing students in three nursing schools in B and C city from November 15 to December 10, 2016, and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Correlations were found between adaptation to university life and life stress (r=-0.657, p<0.001) and between ego-resilience (r=0.455, p<0.001) and spiritual well-being (${\beta}=0.210$, p=0.025)(r=0.494, p<0.001). The adaptation to university life in participants showed a significant correlation between life stress (r=-0.657, p<0.001), ego-resilience (r=0.455, p<0.001), and spiritual well-being (r=0.494, p<0.001). The significant factors influencing the adaptation to university life were life stress (${\beta}=-0.418$, p<0.001), health status(${\beta}=0.213$ p<0.001), spiritual well-being (${\beta}=0.210$, p=0.025), satisfaction with major (${\beta}=0.146$, p=0.003), and ego-resilience (${\beta}=0.109$, p<0.001); these factors explained 56.5% of the variance. The findings suggest that adequate educational strategies are needed to reduce the life stress and increase health status, spiritual well-being, satisfaction on major, and ego-resilience in nursing students to promote their adaptation to university life.

  • This study was conducted to evaluate the effects of physical activity practice rates and knowledge related to cardiocerebrovascular disease prevention on the health behavior of middle aged women. Data were collected from Oct to Nov 2017 from 142 middle-aged women living in 24 Eup, Myeon, and Dong areas in North Gyeongsangbuk-do Province using a structured questionnaire. The obtained data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's correlation, and stepwise multiple regression analysis. The major factors influencing health behavior were found to be alcohol consumption (${\beta}=0.15$, p=0.009), diet (${\beta}=0.16$, p=0.003), vigorous intensity (${\beta}=0.14$, p=0.011), marriage (${\beta}=0.19$, p<0.001), interest in one's own health (${\beta}=0.23$, p<0.001), and health recognition (ill: ${\beta}=0.31$, p<0.001). Alcohol consumption and diet were factors of cardiocerebrovascular knowledge, vigorous intensity was a factor of physical activity practice rate, marriage and interest in one's own health were factors of general characteristics, and health recognition was a factor in health-related characteristics. Health-promotion activity was positively correlated with knowledge regarding cardiocerebrovascular disease prevention (r=0.41, p<0.001) and physical activity practice rate (r=0.44, p<0.001). It will be necessary to develop and apply practical intervention programs based on disease prevention knowledge and physical activity to enhance the health behavior of middle aged women.

  • Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, $SC_{50}$ values of the FHHT was $68.85{\mu}g/mL$, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in ${\alpha}-melanocyte$ stimulating hormone (${\alpha}-MSH$)-stimulated B16F10 cell ($IC_{50}=9.82{\mu}g/mL$). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.

  • The purpose of this study is to compare the educational needs of public officials and private employees for health and welfare in order to improve education program. Data were collected from 2,290 public officials and 1,991 private employees and were analyzed using frequency analysis and independent sample t-test. Private employees recognized that education and training are more enough than public officials. In addition, private employees took the gathering training classes more than public officials. Private employees reported that they are more satisfied than public officials with regard to leader consideration, peers' will of participation and institutional conditions. However, public officials reported that they are more satisfied than private employee officials with regard to the degree of sharing of information and education for new policies. Public officials preferred three or two days of training, but private employees preferred one or two days. Both public officials and private employees preferred gathering training classes and blended learning as an effective education type. Based on this research, invigoration of health and welfare education and the management of its plan were discussed.
