항만인프라의 설계 자동화를 위한 실무형 항만 BIM 라이브러리 개발에 관한 연구
김현승,이헌민,이일수 한국BIM학회 2019 KIBIM Magazine Vol.9 No.4
Many studies on BIM-based design, construction and operation have already been conducted on roads, railways, etc., but BIM research in the ports and harbors is still lacking. This research develops BIM Library and Technical contents focused on practical usability of ports and harbors infrastructure. We have developed technical content by applying various User Interfaces and workflows, considering the characteristics of ports and harbors design. In order to examine the practical utility of the developed library and contents, we tried modeling the breakwater using these. As a result, we confirmed that collaboration of BIM library and technical contents could significantly improve the productivity of BIM design by increasing library usage and automating repetitive tasks.

Purpose: This study was designed to investigate the relationship between the histological composition of the prostate, preoperative clinical parameters, and the results of transurethral resection of prostate (TURP). Materials and Methods: A total of 61 patients with benign prostatic hyperplasia (BPH) who had undergone TURP were enrolled retrospectively. Slides were surveyed for relative areas (%) of glandular epithelium (GE), stroma (ST), and smooth muscle (SM) in stroma by performing immunohistochemistry, and the mean outcomes were calculated with a computer-assisted image analyzer (x200). Results: Total prostate volume was less than 40 ml in 19 patients (group 1), 40 to 80 ml in 23 patients (group 2), and more than 80 ml in 19 patients (group 3). The percentage of SM was significantly greater in group 1 (29.5±4.2%) than in group 3 (23.7±3.2%), but GE and ST did not differ significantly. AG number was significantly higher in group 3 than in the other groups but did not correlate with SM. Improvements in International Prostate Symptom Score, which were similar in each group, were positively correlated with SM. Conclusions: SM in prostate adenoma is increased in men with a small prostate and may play an important role in lower urinary tract symptoms in small BPH.

Purpose : The purpose of this study was two-fold: to investigate the effects of uncertainty and depression on the quality of life (QoL) of elderly people with chronic diseases and to provide basic data on the physical, emotional, and psychological factors affecting their QoL in the field of physical therapy. Methods : A questionnaire covering uncertainty, depression, and QoL was distributed among 320 elderly people. Pearson’s correlation analysis was performed to examine the correlation between uncertainty (ambiguity, complexity, inconsistency, and unpredictability), depression, and QoL (physical, psychological, social, and living environment domains) of the respondents; furthermore, multiple regression analysis was performed to identify the factors affecting the QoL of the respondents with a chronic disease. Results : The sub-factors of uncertainty and QoL—“complexity and social domain” (r=-.295, p<.001), “complexity and living environment domain” (r=-.302, p<.001), and “inconsistency and living environment domain” (r=-.360, p<.001)—showed a negative (-) correlation, as did depression and the sub-factors of QoL—“depression and physical domain” (r=-.782, p<.001), “depression and psychological domain” (r=-.876, p<.001), “depression and social domain” (r=-.668, p<.001), and “depression and living environment domain” (r=-.731, p<.001). The factors affecting QoL were complexity (β=-.122, p<.001), inconsistency (β=-.102, p=.002), unpredictability (β=.112, p<.001), and depression (β=-.850, p<.001). The relative influence of the independent variables was in the order of depression, complexity, unpredictability, and inconsistency, and the explanatory power was 77.1 % (F=215.853, p<.001). Conclusion : It is important to help the elderly with chronic diseases reduce the negative impact on their quality of life by helping them gain support from their families and medical professionals and by increasing their understanding through communication so that they can transition from negative emotions to positive emotions of opportunity.
