  • Tension force of hanger ropes has been recognized and utilized as an important parameter for health monitoring of suspension bridges. Conventional vibration method based on string theory has been utilized to estimate tension forces of relatively long hanger ropes without any problem, however it is convinced that the vibration method is not applicable for shorter hanger ropes in which the influence of flexural stiffness is not ignorable. Therefore, as an alternative of vibration method, a number of feasibility studies of system identification(SI) technique considering flexural stiffness of the hanger ropes are recently performed. In this study, the influence of support condition of the finite element model utilized for the SI method is investigated with numerical examples. The numerical examples are prepared with the specification of the Kwang-Ahn bridge hanger ropes, and it is revealed that the estimation result of the tension force can be varied from -21.6 % to +35.3 % of the exact value according to the consideration of the support condition of FE model. Therefore, it is concluded that the rotational stiffness of the support spring should be included to the list of the identification parameters of the FE model to improve the result of tension estimation.

  • Objective: The purpose of this study was to identify the effects of taping therapy and inner arch support on pes planus lower extremity alignment and gait. Method: The study was conducted on 13 women in their 20s who had pes planus and no gait problems. Independent variables were the condition of wearing basic socks (S1) and the condition of wearing socks with taping therapy and inner arch support (S2). The dependent variables were resting calcaneal stance position (RCSP), plantar pressure distribution during gait, and underlying and medial longitudinal arch angle measured using radiography. Statistical analysis was performed using the Wilcoxon test with SPSS 23.0 for comparison of S1 and S2. Results: In the RCSP measurement, the angle range of S2 changed to normal. Meary's angle appeared to be less than the angle of S1, indicating alleviation of the degree of pes planus. The calcaneal pitch angle increased at S2 from that at S1. The plantar pressure distribution was divided into four areas (toe, forefoot, midfoot, and hindfoot). At S2, the maximum pressure increased in the toe and midfoot. The maximum force increased significantly in the toe and midfoot but decreased significantly in the forefoot and hindfoot. In addition, the contact area increased overall especially at the midfoot and hindfoot. Contact time decreased in the toe and forefoot, but increased in the midfoot and hindfoot. Conclusion: Taping therapy and inner arch support showed structural improvement of the pes planus. In addition, the force and pressure applied to the foot during walking are distributed evenly in the area of the sole, thus positively affecting walking.

  • 접경지역지원법(2000)은 접경지역종합개발계획을 통한 생활여건 개선, 자연환경 보전, 통일기반 조성이라는 정책목표 융합을 천명하고 있다. 이러한 지원성과가 정책목표에 상응하는가, 정책 자체에 문제는 없는가를 평가하는 것이 연구목적이다. 이를 위해 2000년~2014년간 정책목표와 관련되는 통계지표의 변화를 분석하고 지자체의 자체평가와 비교하였다. 그 결과, 많은 집행과정의 문제점에도 불구하고 자연환경적으로 발전이 제약되는 도서 및 산악 접경지역을 예외로 하면 주민의 생활여건은 크게 개선되었다고 평가할 수 있다. 반면 개발위주의 정책은 자연환경을 훼손하고 군사규제와 끊임없이 갈등을 야기하고 있다. 정책목표들 간의 조화가 안정적인 지역발전에 바람직하며, 군사적 대치의 남북관계가 지속되는 한 군사우위의 정책목표체계가 훼손되어서는 안될 것이다.

  • This is a descriptive study on quality of life(QOL) and related factors of ostomates to provide a basic data for development of nursing interventions. The subjects were 110 ostomates who were members of the Daegu or Daejon branches of the Korean Ostomy Association. Data collection was performed between March 1st and April 6th, 1998. Measurements of QOL, self-care, family support, self-esteem, and hope were used as the study tools. Data were analyzed with the SAS program by using t-test, ANOVA Pearson correlation and stepwise multiple regression. The results are as follows : 1) The score on the QOL scale ranged from 97 to 226 with a mean of 164.53($\pm$28.29). 2) The score of QOL on the general and ostomate-related characteristics showed significant differences according to monthly income, monthly participation in ostomate meetings, combined treatments after operation, types of evacuation management, problems of ostomy, help in caring for the ostomy, length of time since ostomate surgery, and presence or absence of readmission after discharge. 3) There were significant positive correlations between quality of life and other factors : self-esteem(r=0.7107, P<0.001), hope(r=0.6584, P<0.001) family support(r=0.6191, P<0.001), perception of health condition(r=0.6017, P<0.001), and self-care (r=0.2286, P<0.05). 4) The variables that affected the quality of life of the subjects were self-esteem, level of family support, perception of health condition, monthly participation in ostomate meetings, combined treatments after operation, monthly income, level of hope, and age in that order. The variance of quality of life was $R^2$=77.20 percent by calculating the sum of those variables. In conclusion, it is necessary for nursing intervention to promote self-esteem, family support, and hope in the care of ostomates in order to improve QOL.

  • Support Vector Machine(SVM)을 이용한 회전기계 진단 연구가 많이 수행되어 왔으나 결함 분류성능은 입력 특징과 더불어 다중 분류 방법, 이진분류기, 커널함수 등에 따라 다르다. SVM 을 이용한 대부분의 기존 연구들은 한번 입력 특징들을 선정하면 결함 분류시 동일한 특징데이터를 이용한다. 본 논문에서는 회전기계의 다양한 결함조건에서 측정한 진동신호로부터 추출한 통계적 특징들을 이용하여 각각의 결함을 분류하기 위한 최적 특징들을 선정한 후, 해당 결함상태를 분류하기 위한 SVM 학습과 분류에 각각 이용하였다. 실험자료를 이용한 검증 결과, 제안한 단계 분류 방법이 상대적으로 적은 학습시간으로 단일 다중 분류 방법과 유사한 분류 성능을 얻을 수 있었다.

  • 이 연구는 사례조사와 인터뷰를 통해 청춘조치원 프로젝트의 주민공동이용시설의 현황과 운영실태를 파악하여 지속적인 운영을 위한 방안을 도출하고자 하였다. 현황 및 운영실태를 살펴보면, 첫째, 조치원읍에는 2025년까지 13개의 시설이 조성예정이지만, 상당수의 시설은 아직 구체적인 운영방안이 마련되지 않고 있다. 둘째, 다른 시설과의 연계를 통한 일자리 및 수익 창출 가능, 유료화 시스템 도입 등을 근거로 지속운영 가능성에 대해 긍정적으로 평가하고 있다. 셋째, 다양한 측면에서 행정지원이 이루어지고 있지만 예산의 한계로 아쉬움이 존재하였다. 지속가능한 운영을 위해 보건복지와 여가문화 기능을 강화하고, 행정지원 측면에서의 지원이 필요하며, 도시재생지원센터 활용하여 지원 및 관리 기능을 강화할 수 있을 것으로 기대된다.

  • Purpose: To identify risk factors for premature birth among premature obstetric labor women. Methods: Participants were 129 hospitalized women who were diagnosed with potential premature obstetric labor with 20 weeks to 37 weeks of gestation. Data were analyzed using descriptive statistics, $x^2$ test, t-test, and binary logistic regression. Results: Of 129 women, 78(60.5%) gave premature birth and 51 (39.5%) gave full-term birth. Risk factors for premature birth were education level (${\leq}$bachelor's degree), abnormal bowel condition (constipation or diarrhea), time firstly diagnosed with a premature obstetric labor (below 28 weeks of pregnancy), and multiple pregnancy. There were also increased risks of premature birth for participants with high level of anxiety and high level of prenatal stress. In social support, there was an increased risk of premature birth for participants with low level of social support. Conclusion: Prenatal nursing programs should consider not only psychosocial factors such as anxiety, prenatal stress, and social support, but also some general and obstetric factors such as education level, abnormal bowel condition, time firstly diagnosed with a premature obstetric labor, and multiple pregnancy to increase maternal and child health.

  • This study was designed to examine the decision-making and family life satisfaction of the urban middle-aged housewives from the ecological perspective. The main purpose of this study was to investigate the effects of ecological enviornment variables(ie, natural physical-biological environment·social-cultural environment·human-built environment) and their dicision-making on their family life satisfaction. Also, it is to provide some fundamental information that helps to elevate the family life satisfaction of the unban middle-aged housewives. The subjects of this study were 305 housewives living in Seoul and Inchon area, whose age was from 40 to 59. The significant results were as follows: 1) Their decision-making was affected by the following variables in the order of health condition, fate-control orientation, husband’s support, monthly family income and the perception of the adequacy of household income. 2) The ecological environment variables which had an influence on family life satisfaction were the perception of the adequacy of household income, husband’s support, fate-control orientation, health condition and educational level. 3) From the regression analysis, the model was found to be highly significant, accounting for 44% of the variance. Thus, husband’s support was the strongest predictor variable.
