The cost of medical treatment for motor vehicle accidents is increasing every year. In this study, we created a model to predict long-term hospitalization(more than 18 days) among minor patients, which is the main item of increasing traffic accident medical expenses, using five algorithms such as decision tree, and analyzed the factors affecting long-term hospitalization. As a result, the accuracy of the prediction models ranged from 91.377 to 91.451, and there was no significant difference between each model, but the random forest and XGBoost models had the highest accuracy of 91.451. There were significant differences between models in the importance of explanatory variables, such as hospital location, name of disease, and type of hospital, between the long-stay and non-long-stay groups. Model validation was tested by comparing the average accuracy of each model cross-validated(10 times) on the training data with the accuracy of the validation data. To test of the explanatory variables, the chi-square test was used for categorical variables.

In this study, professional oral care was provided and 3 times a day twice a week by a dental hygienist for 3 months from July 24 to October 25, 2011, to 43 long-term patients in a single nursing facility located at the city of D, and the number of mutans strepococci colonies within the saliva and the level of salivation were then analyzed after 3 samplings with an interval of 1 month to compare the intraoral conditions among the subjects and examine the effects of professional oral care on the Streptococcus mutans population in the intraoral region of long-term patients in a nursing facility. The level of salivation was elevated from 5.8 ml to 6.4 ml after one month and to 7.5mL after two months. The population of bacteria decreased from $6{\times}10^8CFU/ml$ to $3{\times}105CFU/ml$. In terms of the change in the bacterial population in accordance with systemic diseases, the patients with hypertension and diabetes showed a meaningful decrease in the population. As more dental charge and prosthesis are present, the number of bacteria decreased significantly. On account of the close relationship between a professional oral care and the population of Streptococcus mutans at the intraoral region of long-term patients in nursing facilities, various dental health programs should be researched and developed to consider the characteristics of long-term patients in nursing facilities and manage them continuously but effectively.

국내 입원 스트레스와 관련된 연구는 1970년대 중반부터 꾸준히 지속되어 2000년 중반 이후 급증하였으며, 대다수의 연구가 장기 입원환자를 대상으로 한 서술적 연구였고, 대부분의 연구에서 오래 전에 개발된 Volicer et al.의 HSRS(Hospital Stress Rating Scale)에 기반하여 입원 스트레스를 측정하고 있었다. 따라서 향후에는 한국인의 사회 문화적 특성과 고유한 정서에 맞고 현재 우리나라 의료 실정에 근거한 입원 스트레스를 규명하는 질적연구를 통해 이론적인 지식체를 축적하여야 하며, 이러한 연구결과의 함의에 맞는 측정 도구의 개발로 국외에서 개발된 오래된 측정도구들을 대치할 수 있어야 할 것이다. 또한 단기 입원 환자를 대상으로 입원 스트레스를 경감시키기 위한 중재와 그 효과를 측정할 수 있는 실험연구가 보다 많이 진행되어져야 하겠다.

The purpose of this study is to explore the phenomenon in-depth with its context that what are changes of life in the older patients with social admission by applying the phenomenological research method, and to understand the essential meanings and structure of change experiences of life in elderly patients with social admission. The participants were 15 patients with chronic disease over 65 ages who were selected by convenience sampling. Data were collected through individual in-depth interviews from April to July 2016, and were analyzed using Colaizzi (1978)'s phenomenological analysis method. The essential meanings and structure of change experiences of life in the older patients with social admission were derived into six clusters of themes as follows: 'A lot of concerns are solved', 'New relationship', 'Life as a ordinary person that it looks nothing like a patient', 'The body and mind are comfortable', 'Fear of discharge','Social isolation'. The results of this study contributed to promoting a deeper understanding of change of life in older patients with social admission, and provided for the basic data of strategic approach in solving the social admission problem in long-term hospital.

In the case of long-term hospitalization for young patients, 'Hospital Schools' are operated to pursue school classes and to develop social and emotional abilities for them. However, face-to-face classes at hospital schools have been completely prohibited, and the untact or limited contact environment has been strengthened even for young patients due to the COVID-19 in recent years. Augmented Reality(AR) technology enables the development of experiential content with virtual environments, objects and characters similar to real life. The developed contents should revitalize the imagination of young patients living only in hospitals and allow them to experience, not only acquiring knowledge, but also improving interpersonal skills and sociality. This study is intended to provide diverse adventures and in-depth choice experiences to young patients who are struggling in an environment of untact and limited contact by creating experiential fairy tale contents using AR technology. In addition, long-term hospitalized children will be able to cultivate the will to overcome illness with positive emotions through the augmented reality experience fairy tale content studied and implemented in this study.

This is a non-experimental and retrospective study aimed at determining the effects of long-term hospitalization on the body mass index (BMI) and lipid metabolism in long-term hospitalized patients. The study subjects included 120 patients aged 40-65 years who were hospitalized for >3 months in 2 long-term care hospitals in Gyeonggi-do, South Korea. In this study, the BMI and levels of total cholesterol, triglycerides (TG), high-density lipoprotein (HDL), and low density lipoprotein (LDL) at admission and 3 months after hospitalization were compared and analyzed, and the related changes over time were followed up. The general characteristics of the subjects were analyzed by using descriptive statistics and frequency analysis. In addition, logistic regression analysis was performed to determine the effects of the general characteristics on the BMI and Dyslipidemia. The changes in the BMI and blood lipid levels between admission and 3 months after hospitalization were analyzed using the paired t-test. The results showed that with regard to the changes in the blood lipid levels, the triglyceride levels significantly increased 3 months after hospitalization (p<.05). These findings imply that long-term hospitalization for care and rehabilitation after acute-phase treatment should be considered a potential high-risk factor for dyslipidemia, which could be prevented or alleviated by providing the patients with health education, including exercise and dietary education.

목적: 방사성옥소 치료를 받는 많은 환자들이 장기간의 전처치와 격리 입원 동안에 신체적 불편함을 호소하므로 이를 줄여주기 위하여 첫째, 방사성옥소 치료 전 환자들이 저옥소식을 잘 지킬 수 있도록 도움을 주며 둘째, 4일간의 격리입원기간 동안 심리적 어려움과 신체 적불편함을 줄여줌으로써 환자의 만족도를 향상시키는 효과를 기대하고자 본 연구를 하였다. 대상 및 방법: 1. 연구자들의 브레인스토밍을 통해 환자들의 불편함을 파악하였다. 2. 방사성옥소 치료를 위해 입원한 환자 36명에게 입원 기간 동안 느낀 점을 기록하게 하고 이를 조사하였다. 3. 환자 퇴원시에 치료과정에 대한 만족도 설문을 문제점 개선 전 33명, 개선 후 22명에게 조사하였다. 결과: 문제점과 개선안을 도출하였으며 가능한 범위 내에서 개선활동을 실시하였다. 그리고 만족도 설문을 조사하였으며 개선 전 후를 비교하였다. 문제점으로 1) 저옥소식: 맛이 없다, 반찬 가려 먹기가 어렵다. 2) 치료병실 생활: 속이 메스꺼워 음식 섭취가 곤란하다, 병실이 춥다. 3) 호르몬제 투여중지: 전신이 나른하다, 몸이 붓는다가 도출되었으며 이를 해결하기 위한 개선 활동은 1) 입원 전 예약 시에 음식조절(저옥소식)에 대한 설명을 자세히 하였다. 2) 타부서와의 협의-협조사항(치료병실의 청결유지와 쾌적한 병실을 만들기 위해 16층 병동과 협의, 저옥소식 영양상담을 치료 과정중에 넣기 위해 영양과와 협의, 온열매트리스 설치와 보온이불 구입을 위해 시설팀과 협의 등)을 해결하려 노력했다. 3) 전반적인 개선활동(방사성옥소를 차질없이 구입, 치료병실의 치료 전 후 방사능오염 방지, 환자의 심리적 불안감 해소 등)을 하였다. 환자의 만족도 설문에 대한 개선 활동 전 후 비교 결과에서 '치료과정 전체에 대해 힘들었다'는 개선 전 후에 각각 80.6%, 81.8%로 큰 차이가 없었다. 또한 문제점으로 도출된 '저옥소식이 힘들었다'는 개선 전 후에 각각 24.1%, 27.8%로 역시 큰 차이가 없었다. 그러나 '병실생활이 힘들었다'는 개선 전 후에 각각 48.3%, 72.2%로 큰 차이를 보였다. 그리고 '호르몬 투여중지로 인해 힘들었다'는 개선 전 후에 각각 27.6%, 0%로 큰 차이를 보였다. 고찰 및 결론: 환자들의 불편함을 줄여주기 위하여 연구자들의 개선활동이 있었고 그 중에서 입원병실의 생활환경이 특히 향상되었다. 그러나 결과에서 '병실생활이 힘들었다'에 대한 답의 비율은 오히려 더 높아졌다. 이는 '호르몬 투여 중지로 힘들었다'로 답하는 환자의 비율이 상대적으로 줄었기 때문에 높아진 것으로 생각되었다. 방사성옥소 치료로 인해 생길 수밖에 없는 신체적 반응 때문에 대부분의 환자들은 항상 힘들었다고 할 것이다. 만족도 개선 활동으로 환자의 힘든 치료과정을 완전히 해소시켜 줄 수는 없었으나 환자입장에서 생각할 수 있게 된 계기가 되었으며 좀 더 향상된 치료환경을 제공하는 기회가 되었다.

The purpose of this study was to investigate the determinants of total payment for mental and behavioral disorders patients admitted through the emergency room. Study data was selected from the Korean National Health Insurance sample data in 2009. This data was consisted of 753 inpatients who are 331 inpatients with only main sick(F31-F39) and 422 inpatients with main sick codes(F31-F39) and sub sick(F00-F99) admitted through the emergency room. SPSS v.18 was used for the statistical analysis such as descriptive analysis, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, significant variables affecting total payment of main sick patients were gender(p<.01), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). Also, main sick patients with sub sick were gender(p<.01), age(p<.001), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). These findings implied that it is necessary to build short, middle, and longterm program and system for high risk mental and behavioral disorders groups.

Objectives: The purpose of the study was to compare the oral health related characteristics between a long-term patients and general population. Methods: A direct interview questionnaire was completed by 160 patients and 165 general people from January 16 to April 31, 2014. The questionnaire consisted of general characteristics of the subjects, subjective health status, oral health behaviors, and needs of oral health. The data were analyzed using SPSS 18.0 program. Results: The long-term patients reported that most of them were denture wearers(38.1%), and had oral disease symptoms(62.5%) and xerostomia(65.6%). Most of the long-term patients were ex-smoker(31.3%) and did not receive regular dental check-up(92.5%). They did not know tooth brushing method(31.3%) and brushed their teeth less than twice a day(47.5%). Those who used tooth brush for more than 6 months accounted for 47.5%. Most of them did not use auxiliary oral hygiene devices(85.6%). The patients answered that oral health is not important(6.9%), oral health education is not necessary(7.5%), and oral cleaning(26.3%) should be included in oral health education. Conclusions: The self-reported oral health status of the long-term patients much more serious than the general population. It is necessary to educate the continuing oral health management program for the long-term patients.
