Periodontal therapy has dealt primarily with attempts at arresting progression of disease, however, more recent techniques have focused on regenerating the periodontal ligament having the capacity to regenerate the periodontium. The effect of chitosan(poly-N-acetyl glucosaminoglycan), a carbohydrate biopolymer extracted from chitin, on periodontal ligament regeneration is of particular interest. The purpose of this study was to evaluate the effect of chitosan on the human periodontal ligament fibroblasts(hPDLFs) in vitro, with special focus on their proliferative properties by M'IT assay, the synthesis of type I collagen by reverse transcription-polymerase chain reaction(RT-PCR) and the activity of alkaline phosphatase(ALP). Fibroblast populations were obtained from individuals with a healthy periodontium and cultured with ${\alpha}MEM$ as the control group. The experimental groups were cultured with chitosan in concentration of 0.01,0.1, 1,2mg/ml. The results are as follows; 1. Chitosan-induced proliferative responses of hPDLFs reached a plateau at the concentration of O.lmg/ml(p<0.05). 2. When hPDLFs were stimulated with 0.lmg/ml chitosan, mRNA expression of type I collagen was up-regulated. 3. When hPDLFs were stimulated with 0.lmg/ml chitosan, ALP activity was significantly up-regulated(p<0.05). In summary, chitosan(0.lmg/ml) enhanced the type I collagen synthesis in the early stage, and afterwards, facilitated differentiation into osteogenic cells. The results of this in vitro experiment suggest that chitosan potentiates the differentiation of osteoprogenitor cells and may facilitate the formation of bone.

The purpose of this study was to evaluate the clinical validity of multi-rooted teeth subjected to root-resection treatment. Over a period of 1-7 years, 60 root-resected molars in 59 patients were examined clinically and radiographically. All patients were p0eriodically recalled once or twice a year. Root-resections were due to periodontal, more specifically furcal bone loss or marginal bone loss,in 34 cases and extensive dental carious destruction in 10 cases. In other cases,root-resections resulted from 6 cases of root fracture, 6 cases of periodontal-endodontic combined lesion, and 1 case of endodontic problem. Root-resection was carried out on 26 maxillary molars and 34 mandibular molars. The results are as follows; 1. 14 cases(23.3%) were considered failures. 8 cases(13.3%) of them occurred within the first year(8 cases, 13.3%), 4 cases(6.7%)between 1-3 years, and 2 cases(3.3%) between 4-7 years. 2. 8 cases(13.3%) were considered failures due to periodontal reasons, 3 cases(5%) due to root fracture, 2 cases(3.3%) due to endodontic problem, and 1 case(1.7%) due to prosthetic problem. 3. 37 cases(61.7%) showed up for the recall appointments, and the percentage of failures(13.5%) was lower compared with that of all patients(23.3%). The results of the present study indicate that the prognosis of root-resected teeth is favourable if attention is paid to the selection of proper case and to achieving optimal oral hygiene and periodic check up.

How can this study apply to the Fourth Industrial Revolution and its technologies in social welfare? As a follow-up of the research on the 4th Industrial Revolution, to find out the implications for the application of social welfare through Focus Group Interview and literature studies on how various technologies can be applied to the social welfare site. According to the purpose of this study, two research methods were used for literature data related to the Fourth Industrial Revolution and Focus Group Interview research methods for exploratory research. As a result of the Focus Group Interview, the AI section raised the possibility of promoting resources and transferring information between communities. As a result of the Focus Group Interview, the AI section raised the possibility of promoting resources and transferring information between communities. The development of robots has a positive effect on the rehabilitation of clients and the guarantee of the right to move. The development of 3D printers is said to be easy for customizing the necessary equipment and providing the necessary goods for welfare centers. In the case of drones, they showed closeness with the site. In the big data and sharing economy, it is expected to quickly find out the welfare blind spots based on artificial intelligence big data and prevent them from being excluded. Was raised. In the future, social welfare expertise in the welfare field will not only be a convergence technology of various technologies, but also the reinforcement of expertise to practice client-centered human emotions, empathy, and emotion, and strengthen the skills of face-to-face service, creativity and management according to future changes. It was found that more and more necessary.

부산시민이 인식하는 좋은 죽음과 호스피스에 대한 연구

백정원,김숙남,최순옥,류지선 보건의료산업학회 2016 보건의료산업학회지 Vol.10 No.3

Objectives : In this study, the awareness of hospice and the perceptions on the need for visiting palliative care and what constitutes a good death of the citizens of Busan were investigated. The purpose of this study was to develop a hospice system based on the needs of the citizenry of Busan by seeking solutions for current hospice strategies. Methods : One thousand Busan citizens from 20 to 80 years of age were surveyed in this study. Results : Busan citizens defined a good death as spending less than one month of time in the actual process of dying at home between the ages of 80-89 years. They knew about hospice a little and were aware of its necessity. They also knew about the necessity of visiting palliative care and were interested in receiving it when appropriate but did not know much about it. Conclusions : First, there is a large difference between Busan citizens’ expectations on what constitutes a good death and what a good death really is. Second, Hospice palliative care should be provided to the community. Third, the older the patient is, the more palliative care visits are necessary. Fourth, 40s and 50s must make preparations for hospice palliative care in their future.

Objectives: The purpose of this study was to analyze the recent research trends in health and mental health literacy and suggest their implications for future research. Methods: Ninety six articles on the topics of health literacy and mental health literacy that were published in journals in Korea during the last 10 years analyzed. Results: The majority of articles were published in medical journals, whereas the articles published in social and natural sciences journals were conducted by multidisciplinary research teams and seemed to be increasing generally. The participants studied in the selected articles were mostly older adults followed by adults aged 18 and over, and other various groups including health professionals and immigrant groups. More than 97% of the articles used quantitative research methods. Conclusions: Health literacy mirrors other health inequalities. To increase the level of understanding of health information, studies should be conducted using various variables. It is also necessary to develop a community education program that can be implemented in the community. Futher, the results highlighted the importance of interdisciplinary research. It is hoped that this effort will help solve t health inequality.

CoM 및 서브픽셀 처리에 의한 영상의 경계위치 추정

백정원,김태효,이영철 경남대학교 공업기술연구소 2000 硏究論文集 Vol.18 No.-

본 논문에서는, 영상의 패턴인식에서 에지의 경계를 확실하게 결정하기 위해 주어진 구간의 중앙 값과 서브픽셀(sub-pixel) 처리를 실행하는 알고리즘을 제안하였다. 본 알고리즘은 에지 부근의 기울기 값과 중앙값을 구하기 위하여 램프에지를 일차원 미분을 사용하여 루프에지의 형태로 변환하고, 서브픽셀 단위의 경계위치를 구하기 위하여 CoM(center of Mass)의 오프셋 값을 선정된 기준좌표에 적용하였다. 본 알고리즘을 평가하기 위해서 표준편차 값, 처리시간 및 예측되는 에지의 위치를 Tabatabai 및 Lyvers 알고리즘과 비교하였다. In this paper, a new edge detection algorithm which uses CoM(Center of Mass) method and sub-pixel algorithm is proposed. The procedure of this detector is as fellows; If a edge is ramp edge, we change it to roof edge by the gradient edge detector. To obtain the edge location to sub-pixel resolution, we apply CoM, then applied offset information to the result from CoM procedure. In order to evaluate the performance of this algorithm, we analyzed the standard deviation and the distance between the estimated edge location and the real edge location. We compared the performance with the Tabatabai and Lyvers algorithms.
