Purpose: The purpose of this study was to investigate the present status of falls among inpatients in general hospitals and to identify the fall risk factors that reflect the characteristics of domestic hospitals. Methods: Data were collected between December 15, 2016 and January 15, 2017 from 32 Korean hospitals having 500 or more beds. First, 42 risk factors were extracted based on literature review and expert opinions. Then the importance of each factor was evaluated by 223 nurses from medical and surgical adult ward and intensive care units in 40 hospitals. Results: The incidence rate of falls in 18 hospitals was 3.87 per 1,000 total discharged patients and 0.55 per 1,000 patient-days, and the rate of injury-related falls was 40.5%. Major risk factors for falling were identified as the following: being over 65 years of age, history of falls during admission, physical mobility disorders requiring assistance, physical factors (dizziness or vertigo, unstable gait, general weakness, walking aids, visual problems), cognitive factors (delirium, lack of understanding on limitations), neurological disease, CNS medications Conclusion: The findings provide information that can be in the development of a fall risk assessment tool for inpatients in general hospitals in Korea.

피쳐폰 시대부터 최근 소셜 네트워크 게임(SNG)의 광풍에 이르기까지 모바일 게임은 모바일 폰의 킬러 콘텐츠로써, 큰 시장 규모와 매출을 자랑하고 있다. 게임 분야의 연구 관점에서 보았을 때, 모바일 게임은 플레이 기기의 스펙부터 플레이 환경까지 사용자에게 제약이 많이 주어지므로, 사용자 만족도에 부정적일 것이라는 예측을 할 수 있다. 그러나 대다수의 모바일 게임 사용자는 게임 경험에 굉장히 만족하고 있다. 이에 따라, 제약이라는 개념에 주목하였다. 또한 제약과 지원이라는 개념을 동시에 독립 변수로 설정하고, 이러한 요인이 사용자의 몰입과 만족에 어떠한 영향을 미치는지 설문조사 방법론을 통해 검증하고자 하였다. 분석 결과, 모바일 게임에서는 제약이 몰입에 긍정적인 영향을 미치는 것으로 나타났으며, 제약을 통해 불편함을 느끼는 것이 아니라 만족감을 얻을 수 있음을 확인하였다. 이를 통해 향후 모바일 게임의 UX 디자인 과정에서 해당 연구들의 결과를 활용할 수 있으리라 기대한다.

대학에서의 교양교육이 인간의 기본적인 덕성과 지성을 갖추게 하고 올바른 한 인간으로서 주체성을 키우게 하는 보편적인 교육이라는 것과 체육이 신체활동을 통해 심동적, 인지적, 정의적 성장을 도모하는 전인적 교육활동이라는 것을 고려한다면, 대학의 교양교육과 교양체육은 그 가치와 목표를 같이 하고 있다. 더불어 체육이 지닌 근본적인 특성과 추구하는 가치가 교양교육의 가치와 상통하고 교양교육의 목표를 달성하기 위한 수단으로 매우 유용하다면 교양체육은 교양교육의 중심으로 자리매김하여야 한다. 그러기 위해서, 우리는 현재 교양체육 교과 운용 실태를 보다 면밀히 점검하고, 교양체육 운용에서 제기될 수 있는 문제점을 사전에 차단하거나 문제를 해결하며 교양체육이 나아갈 방향을 모색할 필요가 있다. 본 연구에서는 각 시 도 10개의 국립대학교의 교양체육 운영실태를 분석하였으며, 교양체육 운용에서 발생할 수 있는 문제점을 제기하였다. 또한, 대학 교양체육의 나아갈 방향을 '교양교육의 중심으로 자리매김', '체육학의 특징을 반영한 다양한 교과 편성', '기능 위주의 교육에서의 탈피', '전인적 교육활동으로의 교양체육', '교양체육 수업 기회의 증대'로 구분하여 제시하였다.

Objective: The purpose of this study is to find the tendencies and differences of mother's child-rearing anxiety before and after their children enter into elementary school, to analyze the factors influencing child-rearing anxiety at each time, and thereby to seek a support plan at the time of transition. Methods: The subjects of this study were 181 mothers who participated in two surveys which were conducted before and after their child entered into elementary school. Results: Firstly, mother's child-rearing anxiety before and after their children's entrance into elementary school was at a middle level, but increased significantly when they experienced their children's transition to elementary school. Secondly, mother's child-rearing anxiety, before their children's entrance into elementary school, was influenced by private education, the collection of educational information, cognitive ability, whether or not to develop a work status change plan, and birth order sequentially. Thirdly, child-rearing anxiety after their children's entrance into elementary school was significantly influenced by child-rearing anxiety before their children's entrance into elementary school and the mother's employment. Conclusion/Implications: This study is meaningful in the point that it suggested the necessity for the cooperation between multiple systems, such as systematic and stepwise parenting education, the importance of offering information to educational institutions and local governments, and for work- family support policy to prioritize children in order to support children's successful transition into elementary school.

'Long-life' which has been the perennial interest to human beings also carries the risk of multiple losses such as the death of the family members and friends, the loss of physical and cognitive functions. In that regards, living a long life to be the 'oldest-old' could mean not only a 'symbol of successful aging' but also a hardship and low quality of life at the same time. Therefore, the issue of the quality of life of the oldest old has been the subject of the much of the public and research concern in recent days. While there has been increased awareness about the importance of the subjective aspects of the quality of life and meanings attached to the extended life, most researches on the quality of life of the oldest-old have focused only on the objective conditions of the quality of life such as health, economic status and housing conditions. To overcome these limitations this study aims to explore the subject meaning of 'living a long life' in Korean society by investigating centenarians and their caregivers' interpretations of aging experiences. Qualitative data were gathered from the forty-nine Korean centenarians and their caregivers through in-depth interview. Each interview was tape-recorded and transcribed verbatim. Researchers read each transcript a number of times to get some emerging themes. Most striking result was the fact that most of the centenarians express the 'guilty feelings' and try to offer the 'excuses' about their long life. This results were quite contrary to the results of the studies, done in Japan and western countries like Sweden, United States and Germany, where most of the oldest-old express quite positive interpretations about their long-life and take pride in their longevity. Lack of social support, cohort characteristics of the Korean oldest-old and the cultural interpretations linking the death of children to the long life of older generation are given as possible factors to these unique findings of Korean study. The policy implications of the results are discussed.

Purpose: The purpose of this study was to identify the relationship between fatigue, and self-efficacy in patients with lung cancer. Method: The data was collected from January 21th to April 8th 2001. The study subjects were recruited from K hospital in Pusan, Korea. Their fatigue was measured using the 22-item Revised Piper Fatigue Scale developed by Piper et al. (1998) and translated by the investigators, and self-efficacy was measured using the 10-item General Self-efficacy Questionnaire developed by Lee, Schwarzer & Jerusalem. The data were analyzed by SPSS 10.0 program using frequency, percentage, mean and standard deviation, t-test, ANOVA, Post-hoc test (Scheffe's test), and Pearson Correlation Coefficients. Result: 1) The mean fatigue score was $118.48{\pm}33.02$ (range: 22-220). The scores for sub-dimension were $35.40{\pm}10.06$ in behavior/severity, $25.98{\pm}9.06$ in affective score, $27.88{\pm}10.06$ in sensory score, and $29.22{\pm}8.27$ in cognitive/mood. The mean self-efficacy score was $28.80{\pm}5.85$. 2). There were significant differences in the fatigue of patients with lung cancer on income per month (F=4.651, p= .014), 'present pain' (F=2.601, p= .012), 'change of weight' (F=5.911, p= .005), by general characteristics. 3) There were significant differences in the self-efficacy of patients with lung cancer on 'religion' (F=3.732, p= .031), 'employment status' (F=5.525, p= .003), 'past therapy' (F=2.869, p= .034), by general characteristics 4) There was a significant negative correlation between fatigue and self-efficacy (r=- .528, p= .000). Conclusion: Patients with lung cancer experience fatigue. Increased fatigue is associated with decreased self-efficacy. Nurses must provide patients with nursing care for the less occurrence of fatigue and interventions to manage self-efficacy for them.

During acute stages of hospitalized stroke patients, family caregivers face many challenges. They often experience emotional distress, social isolation, and financial constraints. However, the burden of caregiving of stroke patients in acute stages has never been studied properly. The purpose of this study was to investigate the factors related to the caregivers' burden with acute stroke. The subjects were 123 acute stroke patients and their caregivers who were admitted to neurology and neurosurgery units at Dan Kook University Hospital in Chung-Nam area. An interview was performed with the use of standardized questionnaire which included data pertaining to the patients/caregivers characteristics, caregiver burden (Modified Zarit's Burden Scale), and social support (Personal Resource Questionnaire). Our results showed that the mean burden score was 3.11, indicating high level of burden. Among the sub-domain scores, financial burden was the highest. In univariate analysis, the factors related to caregiver burdens were: inability to communicate between patients and caregiver(p<.001); low cognitive function of the patients(p<.001); low level of ADL(p<.001); the gender of caregiver(p<.001); the current employment status of caregivers(p<.01); the presence of social support for caregiver(p<.001); and the availability of alternative caregivers(p<.001). In multiple regression analysis, social support for family caregivers (87%), low level of patient's cognition (2%), availability of 2nd caregiver (1%), and gender of caregiver (female, 0.4%) were significant explanatory factors of overall burden. The caregivers' burden in acute stages during hospitalization following stroke was high. Recognition of high levels of caregivers' burden and those relating factors affecting caregiver burden may allow us to develop different nursing strategies to unload the level of burden for caregivers in acute stages of stroke.
