Background: This study was performed to identify the incidence of screw in-type lateral anchor pull-out in patients older than 60 years who underwent rotator cuff repair for large to massive rotator cuff tear (RCT). Methods: We reviewed 25 patients over 60 who were diagnosed with large to massive RCT and underwent arthroscopic rotator cuff repair in our hospital from March 2017 to February 2021. Preoperative tear size (anterior to posterior, medial to lateral) was measured via preoperative magnetic resonance imaging (MRI). All 25 patients underwent MRI scanning on postoperative day 1 and at 3 months after surgery. The change of anchor position was measured in axial views on MRI images postoperative day 1 and 3 months after surgery. And it was statistically compared according to bone mineral density (BMD), sex, and number of lateral anchors. Results: Two MRIs (postoperative day 1 and 3 months) in 25 patients were compared. Anchor pull-out occurred in six patients during 3 months (6.7%), and the mean pull-out length difference was 1.56 mm (range, 0.16-2.58 mm). There was no significant difference in the number of pull-out anchors, degree of pull-out difference by comparing BMD (A, BMD≤-2.5; B, BMD>-2.5), sex, or number of anchors used in each surgery (C, two anchors; D, three anchors) (p>0.05). Conclusions: Pull-out of screw in-type anchors was rarely observed and the mean pull-out length difference was negligibly small in our study. The screw in-type lateral anchor seems to be a decent option without concern of anchor pull-out even in elderly patients.

연구목적: 일반적으로 교통사고는 산발적으로 발생하기 때문에 예방 및 방지대책 마련을 위한 현장조사 시 시간적·비용적으로 다양한 한계가 있다. 특히, 코로나 사태 이후 비대면 사회로의 전환으로 현장조사를 대체할 방안 마련이 더욱 필요한 실정이며, 이에 본 연구에서는 부산광역시 사상구를 대상으로 다양한 웹사이트에서 제공하고 있는 로드뷰에 대한 현장조사 대체 활용 가능성을 평가하였다. 연구방법: 연구방법은 '16~'22년간 발생한 교통사고 취약지점을 추출하여 교통안전법 ｢교통안전진단지침｣에서 제공하고 있는 현장조사 평가항목을 기반하여 로드뷰를 분석하였다. 연구결과: 주요 결과 사상구는 사상로, 대동로, 학장로 지점에서 고령 보행자 사고가 가장 취약하였다. 로드뷰를 통해 취약지점을 상세분석한 결과 사상로는 영업용 차량의 통제, 시장 상권에 대한 교통약자 보호 등이 필요하였다. 대동로는 불법 노상 주정차, 경사로 합류 구간 등이 취약하였고, 학장로는 과속이 쉬운 도로 등이 취약하였다. 이러한 분석 결과를 토대로 로드뷰의 현장조사 대체 가능성을 평가하였을 때, 로드뷰는 보·차도 분리성, 안전 시설물의 위치 및 간격 등 대부분 항목을 효과적으로 평가할 수 있었다. 하지만, 실측 수행 등 항목에서는 한계가 있었다. 결론: 즉, 로드뷰는 대부분의 현장조사를 대체할 수 있고, 실측 평가항목은 보조자료로 활용성을 높여 시간적·비용적 절감효과와 동시에 높은 효율성을 나타내는 것으로 판단할 수 있다.

본 연구의 주된 목적은 한국 어린이의 노인에 대한 태도를 명시적 태도와 암묵적 태도로 나누어 그 현황을 탐색하는 것이다. 자기보고식 척도로 측정하는 명시적 연령차별 태도는 사회적 바람직성에 의한 영향으로 인하여 과소 보고될 가능성이 크기 때문에, 본 연구에서는 명시적 태도 측정과 더불어 암묵적 태도 측정 조사를 병행하여 어린이의 연령차별적 태도에 대해 입체적인 이해를 시도하였다. 명시적 태도는 기존연구들에서 사용하는 방식의 자기기입식 조사인 선호도척도, 웃는 얼굴 5점 척도를 통하여 수집하였으며, 암묵적 태도는 아동용 암묵적 연령 연합검사(Children Implicit Age-association Test)를 사용하여 수집하였다. 서울 및 수도권의 초등학교 4~6학년 초등학생 503명을 대상으로 수집한 자료를 기술통계, t-test, 일원분산분석 방법으로 분석하였다. 분석결과, 아동의 노인에 대한 명시적 태도와 암묵적 태도에 차이가 발견되어, 노인에 대한 암묵적 태도는 뚜렷한 부정성을 보였으나 명시적 태도는 그보다 낮은 부정적 성향이 관찰되었다. 이러한 결과는 초등학교 고학년 시기에 이미 노인에 대한 부정적인 이미지를 내면화 하였다는 점, 그러나 편견에 대한 교육, 효 사상 등에 기인하는 사회적 바람직성의 영향으로 인해 명시적 태도 표현이 조절되었을 가능성을 시사한다. 한편 암묵적 태도와 명시적 태도간의 차이는 명시적 태도의 측정 방식에 따라 그 크기가 다른 것으로 나타났다. 노인과 비노인 집단에 대해 독립적으로 응답이 가능한 측정에서는 중립적인 태도를 보인 반면, 독립적인 응답이 불가능한 양자택일의 상황이 주어진 경우에는 노인에 대한 상대적인 선호가 낮은 경향이 발견되었다. 본 연구결과는 아동의 노인에 대한 연령차별적 태도 측정방식의 정교화와 다양화가 요구됨을 의미한다. 또한 아동의 노인에 대한 명시적 태도와 암묵적 태도에 영향을 미치는 요인의 탐색과 함께, 유아와 초등학교 저학년 등 보다 어린아동을 대상으로 하는 후속연구가 필요하다고 본다.

The purposes of study was: 1. To identify the direction and scope of research activities in Korean Nursing. 2. To discuss the unique problems present in Korea that warrant nursing research. 3. To delineate the factors that facilitate and/or hinder nursing research in Korea. This study was conducted at six colleges of nursing in Korea. The schools which were selected had doctoral programs at the time, the data were collected in 1990. Four of the schools were located in the metropolitan area of the capital city, Seoul, and two were in two other cities similar in size. The total population of the study was 283 nurses. The instrument for the research was the English version of Research Profile Questionnaire which was translated into Korean by the researchers and was validated in its translation by two professors. A pretest procedure was done before the data collection process. Of the population of 283, 210 subjects received the questionnaire and 150 subjects responded(71.4%). Excluding incomplete questionnaires, 141 questionnaires were utilized for data analysis. Data were analyzed using descriptive statistics. Responses to open-ended questions were content analyzed for themes and categories. Results of the study were as follows : Respondents currently , involved in nursing research numbered 108(76.6%), but 33(23.4%) did not have any research experience. The inexperienced respondenLs tended to be younger than the experienced subjects and most( 60.6%) were employed in hospitals, while 82.4 percent of the experienced nurses were employed in nursing schools. Among the respondents with research experience, 68.5 percent were involved in one to three projects and 31.5 percent were engaged in four or more projects. The experienced nurses indicated that nursing research in Korea is active. On the other hand, the responses of the inexperienced were that nursing research is not active. The most frequently selected research subjects were patients(76.9%, 83 respondents) followed by nurses, healthy persons and nursing students. The relatively high percentage of healthy persons as study subjects, could be explained as a concern of nurses for healthy persons as well as for ill patients. The aforememioned literature review showed a dramatic change in the kinds of study subjects; approximately 33 percent were patients but 25 percent were healthy subjects of various ages. The hospital was the prevailing research setting(67.6%) but at the same time various community settings were used. This is a changing phenomena in nursing research of Korea. Current research designed to build on previous studies amounted to 75 percent; about 39.8 percem were theory and hypothesis generated. Over 65 recommended additional research focusing on hypothesis-testing 0:' theory building. The previously quoted literature review found that only 4.0 percent of the study quescions were developed from a theoretical framework. The most frequently listed current major focus of nursmg research was stress and adaptation. Patients with cancer, pain, social support and care of the elderly were the next most frequently reported. These concerns may reflect problems associated with a technological and industrializing societyl. The most frequently identified problem was lack of clinical research. The need for replication research and research that contributes to the accumulation of nursing knowledge were found to be rare in Korean research. A need for theory testing and theory construction research was also identified. Although advanced statistical methods were often utilized in nursing research, the results were frequently considered by the interviewers not to be applicable in practice, and readers had difficulty in comprehending the findings. Even though the number of clinical nurses involved in research is increasing, it is still considered inadequate. Among 108 respondents, 83(76.9%) gave lack of time as a barrier to conducting nursing research. Over fifty percent of the respondents reported lack of funding or, personally, low confidence in research skills as barriers. The respondents offered 183 suggestions for future emphasis in nursing research. Among the 51 areas of emphasis, clinical research received the highest number and nursing intervention was next. The findings suggested that nursing research should be based on theory, be related to practice and relevant to the situation of a unique Korean culture.
