Patients with Pressure injuries (PIs) may have pain and discomfort, which results in poorer patient outcomes and additional cost for treatment. This study was a part of larger research project that aimed at prediction modeling using a big data. The purpose of this study were to describe the characteristics of patients with PI in critical care; and to explore comorbidity and diagnostic and interventive procedures that have been done for patients in critical care. This is a secondary data analysis. Data were retrieved from a large clinical database, MIMIC-III Clinical database. The number of unique patients with PI was 2,286 in total. Approximately 60% were male and 68.4% were White. Among the patients, 9.9% were dead. In term of discharge disposition, 56.2% (33.9% Home, 22.3% Home Health Care) where as 32.3% were transferred to another institutions. The rest of them were hospice (0.8%), left against medical advice (0.7%), and others (0.2%). The top three most frequently co-existing kinds of diseases were Hypertension, not otherwise specified (NOS), congestive heart failure NOS, and Acute kidney failure NOS. The number of patients with PI who have one or more procedures was 2,169 (94.9%). The number of unique procedures was 981. The top three most frequent procedures were 'Venous catheterization, not elsewhere classified,' and 'Enteral infusion of concentrated nutritional substances.' Patient with a greater number of comorbid conditions were likely to have longer length of ICU stay (r=.452, p<.001). In addition, patient with a greater number of procedures that were performed during the admission were strongly tend to stay longer in hospital (r=.729, p<.001). Therefore, prospective studies focusing on comorbidity; and diagnostic and preventive procedures are needed in the prediction modeling of pressure injury development in ICU patients.

This study aims to investigate the effects of restrictions in economic activity on the spread of COVID-19 in the Philippines. This research employs daily time-series data of confirmed new COVID-19 cases, Apple mobility trends (i.e., use of public transport to destinations, volume of people driving, and amount of walking to destinations) and Google community mobility (i.e., visits to transit stations, visits to workplaces, and staying-at-home) indicators covering the period February 17 to September 11, 2020. The analysis starts by establishing the correlation pattern of new confirmed COVID-19 daily infections to each independent variable. The results show negative linear correlation of the number of new COVID-19 daily infections with less visit to transit station, increase stay-at-home, less use of public transport, and less amount of walking to destinations. Interestingly, the number of new COVID-19 daily infections indicates some form of positive linear correlation with visits to workplaces and volume of people driving. Moreover, employing robust least square regression via the method of MM-estimation, major findings reveal that across mobility measures, staying-at-home has the highest impact on reducing the spread of COVID-19, followed by visiting transit stations less, less use of public transport, less amount of walking, and less workplace visits.

To determine dining out behaviours of fast foods at five different fast food restaurants of Youido apartment compound in Seoul, a survey was conducted of 460 customers ranging in age from 7 to 29 year, from October 1 to 5th, 1986. Findings are summarized follows: The reasons the customers the fast food restaurants by the highest percentage were the following in the order: 'the atmosphere in which fast food is eaten is enjoyable for the companionship', 'convenient to dining', 'the surroundings and dining equipment are pleasant and hygienic', and 'to be able to stay as long as I want'. The majority of the customers visited the fast food restaurants with their friends between 1pm and 5pm. The fast foods purchased by the customers were mostly for snack rather than a full meal. Preference was a major factor in food selection from available meun items. Ice cream, Kentucky fried chicken, rolled rice with laver I rice cake stew, fried Mandoo were ranged high on the list of liked foods, in contrast, lower preference was for noodle soup, small red bean porridge, pinenut porridge, and persimmon punch.

Purpose. With a sample of cognitively impaired nursing home residents and nursing staff, the following were examined 1) the proportion and nature of aggressive behavior, 2) the frequency and types of aggressive behavior, 3) the difference between the residents who demonstrate aggressive behavior and those who do not demonstrate aggressive behavior (age, mental status, functional status, and pain, length of nursing home stay), and 4) nursing staff responses to aggressive behavior by residents. Methods. A cross-sectional descriptive study design was used. Data were collected from cognitively impaired nursing home residents (N=205) and nursing staff (N=60) at two nursing homes using Ryden Aggression Scale I and II, Mini-Mental State Exam, Modified Barthel Index, Verbal Descriptor Scale, and aggressive behavior management questionnaire. Data were analyzed using descriptive statistics including t-test. Results. About $62.9\%$ residents were found to be aggressive and $38.5\%$ were both physically and verbally aggressive. Pushing, making threatening gestures, hitting, slapping, cursing/obscene/vulgar languages, making verbal threats were occurred frequently. Aggressive residents were significantly older, had more cognitive impairment, had more pain, and stayed longer in the nursing home when compared with non-aggressive residents. Considerable proportion of nursing staff responded to aggressive behaviors inadequately. Conclusion. Aggressive behavior among cognitively impaired nursing home residents is prevalent thus needs to be prevented and reduced. Along with environmental modification, educational programs for nursing staff and family caregivers need to be developed and implemented so that they can have extensive knowledge and skills to manage aggressive behaviors.

The current study analyzed the home range size of the Common Kestrel (Falco tinnunculus) by observation using the natural markings in the suburban area of Busan from December 2009 to May 2010. In all, 26 individual kestrels were observed in the study area, of which 14 individual kestrels were frequently observed (more than five times) and 12 were observed less frequently (less than five times). Mean home range sizes of the 14 frequently observed kestrels were estimated using two different methods (minimum convex polygon (MCP) method and fixed kernel (FK) method): 34.49 ha(2.74-163.96 ha) by 100% MCP, 41.35 ha(3.54-99.02 ha) by the 95% FK, 14.33 ha(0.20-31.57 ha) by the 75% FK and 5.75 ha(0.52-14.74 ha) by the 50% FK. The mean home range size was larger for males than for females estimated at 51.50 ha(15.04-163.96 ha) and 11.80ha(2.74-24.48 ha), respectively, by the 100 % MCP method and 8.02 ha(2.38-14.74 ha) and 2.72 ha (0.52-4.28 ha), respectively, by the 50 % Fixed Kernel method. The home range sizes by sexes in breeding pairs differed during the wintering and breeding seasons; the sizes decreased among females but increased among males during the breeding season. Such differences of home range sizes between sexes could be attributed to parental role division during the breeding season. Females stay in the nest or next to it during laying, incubating, and feeding activities, and males go far away from their nest sites to forage areas for their fledglings for most of the breeding period.

This study has been performed to explore main reasons for staying in paid elderly residential care facilities among the residents. In this study, five males and seven females aged 65 to 82 were asked about main reasons for staying in the facilities. The answers of the qualitative interview were drawn as follows; first, some residents had suddenly decided to move into the facility due to critical life events such as bereavement, serious illness, or supporting problems. Second, some residents had taken a long period of considerations on whether staying home or in the facilities, because their health and family supports gradually diminished over the long life span. On the other hand, a few of them voluntarily chose to stay at the facilities, because they recognized supervised group activities, nutritionally well-planned meals, and health care as major inconveniences. In this study, suggestions were made as follows: first, guiding and settlement programs should be developed for the residents of the sudden events, particularly at early stage of admission. Second, intensive nursing care units should be in separation from healthy independent groups, so that the residents are relieved from stressful contacts with extremely ill patients in the residential area.

The purpose of this study is to evaluate the influence of T-shirt as a movie costume on the modem mass fashion. The way of study is to analyze the changes of men's image with T-shirt as Hollywood actors costume in 50's and 60's. The costumes create the characters with meanings and symbols moreover they lead fashion as well as promoting artistic value of films. At the end of the 19th century, this shirt learnt the ropes in the U.S. Navy well before it won the hearts of sportsmen and workers alike, with its twin virtues of comforts and hygiene. When American soldiers returned home after World War II showing their T-shirts in the sweltering heat of the Tropics, their shirts were as heroic as they were. Furthermore the new stars of Hollywood, going by such names as Marlon Brando and James Dean, gave the T-shirt its rebel cachet and showed the whole world. Be it tom open on Marlon Brando's torso in Elia Kazan's 'A Streetcar Named Desire', or peeping out dazzlingly white from under James Dean's red jacket in 'Rebel Without a Cause', the T-shirt flaunted its sexuality and emanated the sweet smell or revolt. It would be the banner of rebellion for a whole generation. The T-shirt had finally found its way into the history of fashion and was there to stay.d was there to stay.

Korea has pursued an aggressive policy of inviting more foreign-born students to its universities since the late 1990s in the wake of the globalization of education markets and its changing demographic structure. While increasingly more students from Asia come to Korea for study, more than half of the graduates return home upon graduation. Given the issues of brain drain, brain circulation, and knowledge transfer that are raised by such a high return rate, this paper examines the factors that frame the foreign students' decision on their post-graduation careers. By analyzing survey data, we report that Asian students majoring in science, technology, engineering, and mathematics (STEM) are more likely to return than non-STEM majors. This suggests that Korea's aggressive policies of inviting foreign-born students have contributed to brain circulation and knowledge transfer between Korea and the other Asian countries. We also find that scholarships from Korean sources and positive attitudes toward Korean culture and life increase their inclination to stay in the country upon graduation. These findings, however, raise more questions than answers, since it becomes obvious that their post-graduation decisions are highly affected by what Korea as a society provides.

Purpose: The aim of this study was to analyze the correlation of gestational age and birth weight with weight gain of very low birth weight infants(VLBWI) during their hospital stay. Method: This is a 5 year retrospective study of which data were collected through review of medical records. Subjects were 124 VLBW infants with a birth weight more than 1000g and less than 1500g who received neonatal intensive care at the university hospital between January 1, 1997 to December 31, 2001. Result: After calculating the z scores of birth weights and discharge weights, z scores of discharge weight and birth weight were compared with the median weight of a fetus of comparable gestational age based on an intrauterine growth reference. There was a significant difference between z scores of birth weight and discharge weight(t=11.60, df=122, p=0.000). Regardless of intensive care during the prolonged hospital stay, VLBW infants showed slow growth rate compared with the median weight of a fetus of comparable gestational age. Conclusion: VLBW infants developed a poor velocity of weight gain during the prolonged hospital stay after birth. The development worsened during the period of physiological weight loss and regain, and they did not reach to comparable growth rate of normal fetus even at the time of discharge. This poor growth velocity of VLBW infants influence negatively for their future growth. Therefore nureses who work at the neonatal intensive care unit must develop an effective nursing intervention protocol to promote the velocity of weight gain and to conduct the parental educational sessions to emphasize the importance of weight gain for VLBW infants at home.

The purpose of this study was to survey appropriateness of admission and days of care for the cerebral ischemia patients as a basis to provide an effectiveness of hospitalization. The authors retrospectively reviewed the medical records of cerebral ischemia patients in two hospitals from November 1997 to February 1998. Of 194 medical records reviewed, there were 2108 medical days. I t is used a 'Appropriateness Evaluation Protocol' previously developed by Gertman and Restuccia (1981) and translated by Department of Health Management, Seoul National University and Korea Institute for Health Services Management (1993), It was found that the 'Appropriateness Evaluation Protocol' had a high inter-rater reliability(k=.92), Statistical significant was tested by using the percentage, mean, and logistic regression by SAS 6.12. The results were as follows; 1. The appropriate admissions were 87.6%, days of care 63.4%, and the average length of stay $10.9{\pm}6.7$ days. 2. The reasons of inappropriate admissions were for work-up(75.0%) and conservative care (25.0%). Major reasons of inappropriate days of care were 'cases in which the medical purpose of hospitalization has been accomplish or can be addressed in a less setting(45.0%)', and 'cases in which there is a delay in performing the work-up or treatment which required patients is hospitalized (44.4%)'. 3. Appropriate days of care were higher as ageing. Appropriate days of care were higher in patients with lower accademic back ground than those of upper college graduates, and in the patients who enter a hospital via emergency room than out-patients department. Appropriate days of care were higher in the patient with MCA infarction, and lower in the patient with cerebellar infarction than the patient with lacunar infarction. Appropriate days of care were higher in attack first than attack above second, in nomortension patients than hypertensive, and lower in groups who engaged in semi-private room and public room than private room in hospital. Appropriate days of care were higher in shorter length of stay than longer length of stay. 4. Diagnosis, admission path, and appropriate days of care explained appropriate admissions. Diagnosis, appropriate admissions, hypertension explained appropriate days of care. According to the above results, author confirms the substantial amount of inappropriate hospital bed utilization. To reduce inappropriateness, it is necessary to develop some alternative services such as home care services or nursing home with which can be replaced inpatient services and to introduce policy such as case management which includes Critical Pathway for consistent management. And, it should be followed the further study for the effectiveness.
