Purpose: This study was conducted to explore the mediating effect of nutritional status in the relationship between symptom experience and functional status among in patients with lung cancer undergoing chemotherapy. Methods: Subject (N=139) were lung cancer patients visiting the D hospital in B city. Data collection was conducted from May 2016 to February 2017. Seven nutritional status measurement tools, 22 symptom experience tools, and 15 EORTC QLQ-C30 functional scales were used to measure nutritional, symptom, and functional levels. The collected data were analyzed by SPSS / WIN 21.0 using descriptive analysis, Pearson correlation, 3-step regression analysis of Baron and Kenny, and Sobel test. Results: There was a significant positive correlation between symptom experience and nutritional status, a significant negative correlation between symptom experience and functional status, and significant negative correlation between nutritional status and functional status. Symptom experience had direct effect and indirect effects on functional status through nutritional status. Conclusion: For enhancing functional status in lung cancer patients, it is necessary to develop nursing intervention programs to palliate symptoms and improve nutritional status.

Purpose: The purpose of this study was to identify the relationship of fatigue and functional status in patients with cancer. Method: The data were collected from August, 15 to October, 10, 2005. The subjects were recruited from three university hospitals and two general hospitals in B, U, and S cities in Korea. Fatigue was measured using the Fatigue Scale for Cancer Patients, and Functional Status was measured using the Karnofsky Performance Status Index. Result: 1) The mean score of fatigue was $79.72{\pm}21.25$(range: 26-130), and the mean score of functional status was $79.33{\pm}13.02$. 2) There were significant differences in the scores of fatigue by sex, age, marital status, employment, major care-giver, pain, and period after diagnosis. 3) There were significant differences in the scores of functional status by employment, major care-giver, pain, stage of cancer, period after diagnosis, and type of cancer. 4) There was a significant negative correlation between fatigue and functional status (r= -.472, p= .000). Conclusion: Increase in fatigue was associated with decrease in functional status in patients with cancer. Nurses must assess fatigue and functional status when caring for the cancer patients, and provide nursing intervention to relieve fatigue and to improve functional status.

This study analyzed the effects of consumption value of outdoor female consumers on relationship quality and long-term relationship orientation as well as differences in consumption value, relationship quality and long-term relationship orientation by demographic characteristics. A survey was conducted from May 15-22, 2016; subsequently, 336 responses were used in the analysis. Statistical analysis methods consisted of frequency analysis, factor analysis, reliability analysis, t-test, ANOVA, and regression analysis. The results indicate that the consumption value of outdoor female consumers was composed of functional value, emotional value, epistemic value, situational value, and social value. Relationship quality was composed of satisfaction, commitment, and trust. Consumption value (functional value, emotional value, epistemic value, situational value, and social value) of outdoor female consumers positively affected satisfaction. Emotional value, epistemic value and situational value positively affected commitment; in addition, functional value and emotional value positively affected trust. Satisfaction, commitment, and trust about outdoor brand also positively affected the long-term relationship orientation; in addition, consumption value positively affected long-term relationship orientation. There were significant differences in the consumption value and relationship quality by age and marital status. The study results provide useful information for the marketing strategies of outdoor brands that consider female consumers.

Purpose: The purpose of the study was to identify the sequential mediating effects of grit and depression on the relationship between negative parenting style and functional somatic symptoms. Methods: This was a secondary analysis of data from the 2018 Korean Children and Youth Panel Survey (KCYPS). Mediation analysis was conducted using the PROCESS macro model 6. Results: The mediating effects of grit and depression between negative parenting style and functional somatic symptoms were significant. A negative parenting style was found to significantly affect functional somatic symptoms going through sequential mediating effects of grit and depression. Conclusion: To alleviate functional somatic symptoms in adolescents, it is necessary to provide interventions for developing grit that could reduce depression.

This study verified the mediating effect of perceived value and the influence of kiosk device characteristics on relationship continuity intention to solve the difficult problems of hotel companies due to the development of current technology and hotel recruitment problems. Two hundred thirty-nine consumers who used kiosk devices in hotels were analyzed using SPSS 23.0 and Smart PLS 4.0. As a result of analysis and verification, it was found that the kiosk characteristics (playfulness, convenience, reliability, usefulness) had a significant effect on all perceived values (emotional value, functional value), and the perceived value also had a significant effect on the relationship continuity intention. Appeared as a result of the influence. However, it was found that the mediating effect of functional value in the relationship between convenience and usefulness among kiosk characteristics was dismissed. These results support the previous studies on hotel kiosks and have academic implications, as well as practical implications for practitioners of hotel companies.

Purpose: This study was to identify the levels of functional status, depression, family support and their relationship among those variables in head and neck cancer patients. Method: The subjects were 100 patients with head and neck cancer patients who visited at outpatients clinic in one university hospital in Taegu. The instrument used for this study were Functional Status in Head & Neck Cancer - Self Report Scale developed by Baker(1995), Self-Rating Depression Scale by Zung(1965) and Family support assessment tool by Kang hyun-suk(1984). The data were analysed percentage, mean, t-test, ANOVA and pearson's corelation using SAS program. Result: There was significantly negative correlation between functional status and depression(r=-.71) and between depression and family support(r=-.56). The relationship of functional status and family support was significant as r= .33. Conclusion: It was found that functional status, depression and family support of head and neck cancer patient were closely related each other. Therefore it is necessary to design nursing intervention to enhance family support or decrease depression for improving quality of life in head and neck cancer patient.

Objective: In this study, we used resting-state fMRI data to map differences in functional connectivity between a comprehensive set of 8 distinct cortical and subcortical brain regions in healthy controls and Internet addicts. We also investigated the relationship between resting state connectivity strength and the level of psychopathology (ex. score of internet addiction scale and score of Barratt impulsiveness scale). Background: There is a lot of evidence of relationship between Internet addiction and impaired inhibitory control. Clinical evidence suggests that Internet addicts have a high level of impulsivity as measured by behavioral task of response inhibition and a self report questionnaire. Method: 15 Internet addicts and 15 demographically similar non-addicts participated in the current resting-state fMRI experiment. For the connectivity analysis, regions of interests (ROIs) were defined based on the previous studies of addictions. Functional connectivity assessment for each subject was obtained by correlating time-series across the ROIs, resulting in $8{\times}8$ matrixs for each subject. Within-group, functional connectivity patterns were observed by entering the z maps of the ROIs of each subject into second-level one sample t test. Two sample t test was also performed to examine between group differences. Results: Between group, the analysis revealed that the connectivity in between the orbito frontal cortex and inferior parietal cortex, between orbito frontal cortex and putamen, between the orbito frontal cortex and anterior cingulate cortex, between the insula and anterior cingulate cortex, and between amydgala and insula was significantly stronger in control group than in the Internet addicts, while the connectivity in between the orbito frontal cortex and insula showed stronger negative correlation in the Internet addicts relative to control group (p < 0.001, uncorrected). No significant relationship between functional connectivity strength and current degree of Internet addiction and degree of impulsitivy was seen. Conclusion: This study found that Internet addicts had declined connectivity strength in the orbitofrontal cortex (OFC) and other regions (e.g., ACC, IPC, and insula) during resting-state. It may reflect deficits in the OFC function to process information from different area in the corticostriatal reward network. Application: The results might help to develop theoretical modeling of Internet addiction for Internet addiction discrimination.

As the most widely used media of BtoB e-business, the e-Marketplace (EM) can play an important role in the age of c-commerce (collaborative commerce). In supply chain management (SCM) area, the relationship-based collaboration among partners has shown great efficiency. Although the collaboration is important in both areas of EM and SCM there has been a critical difference in the selection of trade partners between them. In this paper, the EM's collaborative stages for integration with its customer system are reviewed and a system architecture is proposed for EM's electronic functional role within the perspective of collaborative commerce and buyer-supplier relationship. The relationship-based BtoB commerce through EM is reviewed to explain that it can be more beneficial than the commerce based on the price competitive selection of trade partners. With the proposed system architecture, an EM can be the functional medium for the collaborative IOIS system architecture.
