Purpose : This study investigates the experiences of patients in intensive care units (ICUs), and the factors influencing these experiences. Method : We used a cross-sectional survey design to analyze previously collected cohort data from 891 patients who spent over 24 hours in 19 ICUs across four university hospitals in Busan, South Korea between June 2019 and July 2020. Within a week of ICU discharge, participants completed the Korean version of the Intensive Care Experience Questionnaire, covering four areas: "awareness of surroundings," "frightening experiences," "satisfaction with care," and "recall of experiences." We used multiple linear regression to identify factors associated with the ICU experience. Results : Low income (𝛽 = -.08, p = .016), unplanned hospitalization (𝛽 = -.09, p = .006), sedation (𝛽 = -.16, p < .001), and delirium (𝛽 = -.15, p < .001) reduce patients' awareness of their surroundings. Frightening experiences are associated with being female (𝛽 = -.07, p = .027), experiencing delirium(𝛽= -.15, p<.001), and longer stays in the ICU (𝛽= -.14, p <.001). Using sedatives decreases satisfaction with care (𝛽 = -.08, p = .048). Living alone (𝛽 = -.08, p = .013) and using painkillers (𝛽 = -.08, p = .020) reduces recall of experiences. Conclusion : Negative ICU experiences are significantly associated with being female, living alone, lower income, unplanned admission, using sedatives and painkillers, delirium, and longer stays in the ICU. Thus, improving ICU experiences requires interventions that address modifiable factors, such as delirium, medication, and length of ICU stays.

In recent years, the rapid proliferation of domestic and global Over-The-Top (OTT) platforms, in conjunction with the global pandemic, has substantially enhanced the accessibility of global contents. This trend is expected to continue to strengthen. This study examines the extent to which domestic consumers experience global contents through OTT platforms and its impact on individual consumers' global identity and the formation of global brand attitudes. We conducted an empirical analysis based on a survey of university students, who constitute the main consumer group for global contents through OTT platforms. The results show that as exposure to global content s and diversity of those experiences through OTT increase, respondents exhibit higher levels of global consumer orientation and global identity. This, in turn, has a positive influence on the formation of global brand attitudes.

In this study, we aimed to examine the feasibility of establishing a shared preservation center with a focus on the Chungcheongbuk-do Office of Education. We conducted surveys to assess the current situation and gather perceptions. The research findings revealed the following: Firstly, the surveyed school libraries were already experiencing extreme levels of book saturation, necessitating the management of book saturation and proper book quantity. Secondly, very few libraries had the facilities required for book preservation. Thirdly, the research showed that in 78% of school libraries, book saturation already exceeded 75%, leading to a rapid increase in discarded books each year. Therefore, there is an urgent need for the systematic expansion of a shared preservation center. Moreover, given the difficulty of individual libraries in establishing facilities for preservation, valuable materials such as rare books and specialized resources should be transferred to a shared preservation center. Additionally, policies and regulations related to material preservation are deemed necessary.

Objective: To investigate the long-term effects of maxillary skeletal expander (MSE) treatment on functional breathing. Methods: Objective measures of breathing, the peak nasal inspiratory flow (PNIF), and peak oral inspiratory flow (POIF), and subjective measures of breathing, the visual analog scale (VAS) and nasal obstruction symptom evaluation (NOSE) survey, were used to investigate the long-term effects of MSE in functional breathing. Seventeen patients, mean age 19.4 ± 3.9 years treated at the UCLA Orthodontics Clinic were assessed on their functional breathing at 3 timepoints: pre-expansion (T0), post-expansion (T1), and post-orthodontic treatment (T2). Results: Immediately after expansion (T1), all the objective functional breathing values were significantly increased in comparison to T0 (P < 0.05). The VAS total, VAS right and VAS left were significantly lower at T1 in comparison to T0 (P < 0.05). At 26.8 ± 3.9 months after MSE expansion (T2), PNIF total, PNIF right, PNIF left, and POIF were significantly higher when compared to T0 (P < 0.05). Also, VAS total, VAS right and VAS left were significantly lower at T2 when compared to T0 (P < 0.05). Additionally, there was a positive correlation between PNIF and the magnitude of expansion at anterior nasal spine and zygomaticomaxillary point (ZMA). There was a positive correlation between total VAS and the magnitude of expansion at the ZMA. There were no significant changes for the NOSE subjective breathing measurement at all time comparisons. Conclusions: Overall, MSE treatment produces an increased objective and subjective airway improvement that continues to remain stable in the long-term post expansion.

The number of elderly in care facilities is increasing in parallel with a rapid increase in the elderly population in Korea. We analyzed the meal satisfaction ratings, food preferences, and nutritional intakes of 74 patients aged ≥65 years living in a nursing hospital in Daegu. Food preferences were high for cooked rice, rice gruel, meat soup, soybean paste stew, beef, frozen pollack, squid, egg, spinach, sea mustard, cabbage kimchi, apple, peanut, drinking yogurt, pickled perilla leaves, and salted squid. Preferences for duck (P<0.01) and vegetable (P<0.01) cooking method were significantly different for men and women, and preference for soybean paste stew increased with age (P<0.05). Regarding nutrient intakes, men had higher energy (P<0.01), carbohydrates (P<0.05), and zinc (P<0.05) intakes than women, while women had higher vitamin C (P<0.05) intake than men. Furthermore, energy (P<0.001), carbohydrates (P<0.001), protein (P<0.05), dietary fiber (P<0.01), vitamin B₆ (P<0.01), phosphorus (P<0.05), and zinc (P<0.001) intakes significantly decreased with age. Men had a significantly higher nutrient adequacy ratios (NARs) for carbohydrates (P<0.05) and cal- cium (P<0.01) than women, while women had a significantly higher NARs for protein (P<0.05), vitamin A (P<0.01), vitamin C (P<0.05), thiamine (P<0.01), riboflavin (P<0.001), iron (P<0.001), and zinc (P<0.01). Mean adequacy ratios were 0.69 for men and 0.75 for women. In particular, NARs for carbohydrates (P<0.01), vitamin B₆ (P<0.01), and calcium (P<0.05) decreased significantly with age. In summary, the study shows that supplementing vitamin C, vitamin B₆, calcium, and iron, reducing sodium, and providing meals that reflect preferences will improve the nutritional statuses of elderly residents in a nursing hospital.

The concrete structures in Metropolitan city are usually exposed to carbonation and corrosion of embedded steel occurs due to the carbonation. In inspection and diagnosis of concrete structures, carbonation depth in sound concrete is mainly evaluated and service life for concrete structure is predicted based on the result. Generally, however, mass concrete structures such as columns have construction joint for suitable placing and also have cracks in early-age. In this study, carbonation depth in RC columns used for 20 years in metropolitan city is evaluated and also analyzed by considering the local conditions like sound, cracked, and joint area. The carbonation depth in cracked and joint area is more rapid than that in sound area, and it is thought to be more desirable to consider this effect in concrete structures with small cover depth. Furthermore, the technique for carbonation prediction in cracked concrete is derived in terms of crack width and the results from this technique are verified by comparing those from previous research.
