Purpose: This study aimed to conduct a job analysis of nurse carecoordinators and to identify the frequency, importance and difficulty of each task of their job. Methods: A committee for developing a curriculum (DACUM) was formed and members of the committee defined nurse care coordinators' jobs and enumerated the duties, tasks and task elements by applying the DACUM technique. Then nurse care coordinators enrolled in the pilot project evaluated the frequency, importance and difficulty of each task. Results: From the job descriptions of nurse care coordinators, we identified 12 duties and 42 tasks. Each task comprised 1~5 task elements. Among tasks, 'assess the patient's general health status' was carried out most frequently. Nurse care coordinators perceived that 'check vital signs' and 'strengthen patient competence to promote health behaviors' were more important than all other tasks. The most difficult task was 'develop professionalism as a nurse care coordinator'. Conclusion: The nurse care coordinators' roles developed in this study will serve as the key guidelines for human resource management of care coordinators. Further, job specifications for nurse care coordinators need to be developed, which is necessary for designing education and training programs. We also need to integrate primary health care as an essential component in nursing education.

The purpose of this paper is to find out the way of utilizing phrases of Chinese poetry in Manjeongje and its musical characteristics. To this end, the roles of phrases contained in the Pansori words were classified into five patterns: landscape description, strengthening of pleasant emotions, strengthening of sad emotions, wordplay, and combination of various poems. As a result of analysis, phrases quoted in sad mood part consist of slow rhythm of Jinyangjo and Jungmori, and sad melody of Gyemyun-gil and Jingyemyun tone; thus, both the rhythm and melody are expressed in accordance with the mood of poems. On the other hand, the melody in the landscape description parts, and the rhythm in the joyful feeling and wordplay parts showed the characteristics of determining the mood. In addition, when applying the analysis results to the perspective of Pansori composition, it is necessary to discover novel texts, apply to editorials, and study musical implementation suitable for the original mood in order to create more artistic Pansori.

Scriptwriters have appeared in Korea's broadcasting production system for more than 40 years as a key producer. This study specifically investigated the work identity and labor experience of scriptwriters who have played countless roles from planning and organizing programs in various broadcast genres such as non-drama informative program, entertainment, news, and radio to script writing. As a result of examining the work identity and labor experience of the scriptwriters based on the auto-ethnography of the 20 scriptwriters working in the field, they felt that they had an " indispensable" program producer and a media culture producer and at the same time felt that they were taking on tasks that were unclear. They felt that the cause of this inequality was a problem of the production system and employment type, but they recognized that they could not be solved individually, and they were developing their own skills or building connections to get work, and expanding their areas unconditionally.

Student pilots receiving flight education are inexperienced in piloting and situation judgment skills and are greatly affected by various factors such as psychological, physical, and environmental factors. In particular, one of the most influential factors in the flight education of student pilots is the weather conditions. Unlike large aircraft used in the air transportation business, small aircraft used for flight education have a great impact on education, such as flight restrictions depending on weather conditions, psychological pressure in severe weather, and deterioration of student skills. Therefore, in this study, the meteorological characteristics of meteorological factors that have a great influence on small aircraft were analyzed. As a result of the analysis, an efficient and safe training operation method was suggested to a professional pilot aviation training organization through the adjustment of the training period for the season, the increase in aircraft operation rate, and a safe solo flight plan considering the weather.

This study was a randomized before-and-after design of 17 subjects in the experimental group and 17 subjects in the control group to investigate the effects of listening to relaxing music on the mood state and autonomic nervous system, that is, heart rate of hospitalized patients with mental illness. The collected data were analyzed with SPSS V15.0. There was a statistically significant difference between the two groups in mood state and autonomic nervous system, that is heart rate and the effect of listening to relaxation music was objectively verified(<.05). among the subdomains of mood states, tension(<.00), depression (<.00), vitality (<.03), fatigue () <.01), excluding anger (>.39) and confusion (>.33) showed a significant difference, proving that it is an effective intervention method applied to hospitalized mentally ill patients. In the future, we would like to suggest long-term intervention research and development and application, and research on the effect of mood change and heart rate using individual preferred music.

Objectives: To investigate the protective effect of hesperidin and hesperetin against oxidative stress in 2,2'-azobis (2-aminopropane) dihydrochloride (AAPH)-induced liver toxicity in rats. Methods: Hesperidin or hesperetin (200 mg/kg/day, respectively) was orally administered for 7 days once daily in rats. Subsequently, AAPH (50 mg/kg/day) was administered intraperitoneally. Lipid peroxidation, nitric oxide production, catalase activity, and protein expressions of nuclear factor-kappa B (NF-κB) and inducible nitric oxide synthase (iNOS) in the liver tissues were measured. Results: Administration of hesperidin and hesperetin significantly decreased serum aspartate transaminase and alanine transaminase levels in AAPH-induced oxidative stress liver tissues compared with control group. Lipid peroxidation and nitric oxide (NO) production were also significantly reduced by hesperidin and hesperetin in AAPH-induced oxidative stress liver tissues. In particular, lipid peroxidation levels of hesperetin-administered group significantly decreased to 5.02 nmole/mg protein in oxidative stress rats. Hesperidin and hesperetin significantly increased antioxidant activity, such as that of catalase. Furthermore, administration of hesperidin and hesperetin substantially down-regulated the expression of NF-κB and iNOS in liver tissues. Administration of hesperidin reduced NO levels and iNOS expression more than in the hesperetin-administered group. Conclusions: Administration of hesperidin and hesperetin led to a reduction in AAPH-induced liver toxicity by regulating oxidative stress.

Objectives: This study compared the nutritional intakes of early and late preterm infants in a neonatal intensive care unit (NICU) and at home. The dietary problems and the need for community care services for premature infants were further investigated. Methods: This is a cross-sectional and descriptive study on 125 preterm infants and their parents (Early preterm n = 70, Late preterm n = 55). The data were collected by surveying the parents of preterm infants and from hospital medical records. Results: No significant differences were obtained between the early and late preterm infant groups when considering the proportion of feeding types in the NICU and at home. Early preterm infants were fed with a greater amount of additional calories at home and had more hours of tube feeding (P = 0.022). Most preterm infants had feeding problems. However, there was no significant difference between early and late preterm infants in the mental pain of parents, sleeping, feeding, and weaning problems at home. Many parents of preterm babies had no external support, and more than half the parents required community care to take care of their preterm babies. Conclusions: Regardless of the gestational age, most preterm infants have several problems with dietary intake. Our study indicates the need to establish community care services for preterm infants.

This study examined the effects of platforms' attributes(economy, convenience, ease of use, and security) on perceived usefulness, perceived enjoyment, trust, and the continuance intention to use. Data were collected through a survey conducted with 327 users of second-hand luxury goods trading platforms in their twenties and thirties; 300 were used for statistical analysis using SPSS26.0 for exploratory factor analysis and correlation analysis, and AMOS 26.0 for confirmatory factor analysis and structural equation modeling. For the attributes of second-hand luxury goods trading platforms, four factors were extracted: economy, convenience, ease of use and security. The results showed that only the security of second-hand luxury goods platforms had a positive effect on the perceived usefulness of the platform, but other attributes did not influence perceived usefulness. In contrast, all attributes of the platform showed positive effects on perceived enjoyment. Perceived enjoyment had a strong effect on trust; however, perceived usefulness did not affect trust. The continuance intention to use the platforms was most influenced by perceived usefulness, trust, and perceived enjoyment, in that order. The current findings can help marketers of second-hand luxury goods platforms optimize the platforms' attributes based on the marketing objectives and develop strategies to build perceived usefulness and enjoyment first, and in turn, trust and intention to use.
