우리나라 노인들 평균수명이 늘어나면서 고령화로 인한 노인의 건강에 대한 문제가 많이 발생하고, 치매 발병률이 증가되고 있음으로 인해 사회적으로 심각한 수준에 이르고 있다. 치매는 발병 후 치료보다는 예방이 중요한 만큼 노인의 치매 예방에 관심이 모아지고 있다. 본 연구를 위해 양수경, 고보숙, 박정환(2019)의 연구에서 2000년~2018년까지 노인을 대상으로 한 치매예방프로그램의 국내 연구동향에서 분석한 통합프로그램 11편을 기반으로 유아교육에서 이루어지고 있는 놀이를 중심으로 한 노인 치매예방프로그램 문헌연구를 살펴보았다. 활동유형별로 음악, 언어, 신체활동이 각각 4개(40.0%)로 나타났고, 게임, 미술, 작업이 각각 3개(30.0%)로 나타났다. 그리고 무용, 문학, 전통놀이, 레크레이션이 2개(20.0%)로 나타났고, 요가와 생활은 각각 1개(10.0%)의 순으로 나타났다. 본 연구에서는 노인 치매예방프로그램에서 유아교육 콘텐츠의 활용 가능성에 대해 탐구하는 것을 목적으로 노인에게 있어 놀이는 유아 뿐만 아니라 노인들에게 신체 운동능력과 긍정적인 정서, 정서적 특성 등 매우 긍정적인 측면이 나타나고 있다. 노인들을 위한 유아교육 콘텐츠를 활용하여 치매예방프로그램을 개발한다면 지속적인 서비스 제공과 함께 집단활동의 경험과 정신건강을 유지하면서 여가시간을 긍정적으로 활용할 수 있을 것이라고 사료된다. As the prevention of dementia is more important than the treatment after the onset, attention has focused on the prevention of dementia in the elderly. For this study based on 11 integrated programs, we analyzed the domestic research trends of dementia prevention programs for the elderly from 2000 to 2018 in the study of Yang Su-gyeong, Ko Bo-sook, and Park Jeong-hwan (2019) We reviewed the literature research on the elderly"s dementia prevention program centered on play. By activity type, music, language, and physical activity were 4 (40.0%), respectively, and games, art, and work were 3 (30.0%), respectively. Dance, literature, traditional play, and recreation were 2 (20.0%), and yoga and life were 1 (10.0%), respectively. In this study, for the purpose of exploring the possibility of using the contents of early childhood education in the elderly dementia prevention program, play shows very positive aspects such as physical exercise ability, positive emotions, and emotional characteristics for the elderly. It is considered that if dementia prevention programs are developed using the contents of early childhood education for the elderly, they will be able to utilize leisure time positively while providing continuous services and maintaining group experiences and mental health.

The rapid mixing process for coagulation is a critical component in a water treatment plant. However, at the present time a detailed understanding of the rapid mixing by in-line mixer or generally accepted criteria for the design of in-line static mixer are not available. The aim of this work is therefore to improve the understanding of how the in-line static mixer works and how to better utilize it in coagulation process in water treatment. To investigate the performance of static mixer, coagulation experiments were conducted to compare the static mixer to the traditional backmixer under several coagulation conditions. Experiments were also performed to compare the coagulation efficiency of different mixing type of static mixer which were made using different flow rates and the number of elements equipped in a pipe. The static mixer performed better than the backmixer for all coagulation and mixing conditions tested. Especially, the static mixer was very effective in the surface charge neutralization, as showing higher reduction of negative charge with increasing mixing intensity. However, little difference was observed in the performance of the static mixer equipped with 2, 3, and 5 elements. Also, in a series of bench-scale studies of rapid mixing, the in-line static mixer performed better than the traditional backmixer for both adsorption and charge neutralization (A/N) mechanism and sweep coagulation mechanisms. Especially, the static mixer was more efficient at producing A/N mechanism conditions as a result of its fast and uniform dispersion of the coagulant.

본 논문은 수동형 밀리미터파 영상 시스템을 이용하여 은닉된 물체의 영역을 검출에 관한 연구이다. 밀리미터파 영상은 악천후에도 영상 촬영이 가능하고 플라스틱, 종이, 나무, 옷, 머리카락 같은 특유한 물질들을 투과한다. 그리고 밀리미터파는 금속과 특수한 인공 구조물에 대한 반사율이 높기 때문에 은닉된 물체를 쉽게 검출할 수 있다. 본 논문에서는 밀리미터파 영상에서 은닉된 물체 검출의 영상 분할을 자동 문턱치 방법으로 나타낸다. 본 논문에서는 8㎜ 파장을 수평과 수직 편광 방향으로 수신하는 두 채널에서 획득된 밀리미터파 영상을 Gonzalez와 Otsu 방법으로 영역 분할을 한다. 실험 결과는 Gonzalez과 Otsu 방법 모두 은닉된 물체 영역의 형태를 잘 분리하지만 Otsu 방법이 노이즈와 몸체 영역의 경계 부분이 안정적으로 영역 분할됨을 보인다. We address an image segmentation method to detect concealed objects captured by passive millimeter wave (MMW) imaging. Passive MMW imaging can create interpretable imagery on the objects concealed under clothing. Due to the penetrating property of the MMW imaging, the MMW imaging system is often employed for the security and defense system. In this paper, we develop automatic thresholding methods for the segmentation of concealed objects detected by PMMW imaging. The automatic thresholding method is useful for the image with bimodal distributions. We compare several thresholding methods for two MMW channel images which have 8 mm-horizontal and 8 mm-vertical polarization, respectively. The experimental results show that concealed weapon area is well segmented from the background body by the presented methods.

This paper presents a novel method of signature-based video cut detection in a transform domain. First, we partition a video frame into m x n cells and extract DC information from DCT coefficients. We construct frame signatures using extracted DC information and then compare neighbor frame signatures to detect a cut. The conventional methods have the problems of complex calculation, exhaustive processing time, and strong space. The proposed method is an effective and simple method which may solve the problems of these conventional methods. In the experiment using real AVI video data, our method shows about 88% cut detection rate.

Purpose : The purpose of this study was to investigate factors influencing burden in primary caregivers caring for an elderly person who has had a stroke. Method : A convenience sample of 124 primary caregivers of elderly people with a stroke admitted to an oriental medicine hospital participated in this study. Interviews were done with a standardized questionnaire including Caregiver Burden Scale (Chang, 1995). Result: Average burden score was 93.19, indicating a moderate to severe level of burden. Time-dependent burden had the highest score of the sub-domains. For general characteristics, the factors significantly influencing caregiver burden were gender and age of the elderly person, age and educational level of the caregiver, whether living together or not, and the presence of another caregiver. Multiple regression analyses demonstrated that level of ADL of the elderly person, relationship between the elderly person and the caregiver prior to the stroke, caregivers' relation to the elderly person and primary income were significant factors in explaining variance in overall burden. Conclusion : Recognition of high levels of caregiver burden and factors influencing burden will allow us to develop different nursing strategies to decrease caregiver burden in those caring for an elderly person with a stroke.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

Background and Objectives: The etiology and pathogenesis of chronic rhinosinusitis (CRS) is multifactorial and the role of infectious agents in CRS is not clear. S. aureus is the most frequent cultured pathogen in CRS and it expresses toxin, SEA, SEB and TSST-l, with superantigen (SAG) activity. Recently an importnat role of these staphylococcal toxins in CRS with nasal polyposis (CRSwNP) has been suggested. CRSwNP is a severe chronic inflammation characterized by massive infiltration of lymphocytes and eosinophils in the sinonasal mucosa and nasal polyp. However, there has been no further studies evaluating the properties of infiltrating T lymphocytes in CRSwNP and the cytokine profiles in activated T-Iymphocyte relating with SAGs. The aims of this study was to know what kind of T lymphocytes infiltrates in nasal mucosa and polyp tissue of CRSwNP, to analyze the cytokine profiles in infiltrating T cells, and to determine whether infiltrating T lymphocytes are specific for SAGs. Patients and Methods: Ethmoid sinus mucosa and polyp tissue samples were collected from 13 patients with CRSwNP and control sinus mucosa were obtained from 10 patient without CRS. Tissue infiltrating cells and T cells were isolated from tissue samples and flow cytometry, enzyme-linked immunosorbent assay, reverse transcriptase-polymerase chain reaction, in vitro T lymphocyte stimulation with S. aureus toxin were performed. Results: The mean total CD3+ T cell count was significantly higher in the mucosa and polyp tissue of patients with CRSwNP compared with control mucosa. Most infiltrating T cells in mucosa and polyp tissue were activated type, expressing CD45RO. CD8+ T cells were significantly increased in mucosa and polyp tissue of patients with CRSwNP compared with CD4+ cells IFN-γ was highly expressed in infiltrating T cells in both mucosa and polyp tissue, whereas IL-10 was expressed a small amount and IL-4 was not expressed. IFN-γ levels were significantly higher than IL-4 and IL-10 when isolated T cells were stimulated with SAGs in vitro. Conclusion: CD8+ T-cytotoxic and IFN-γ producing Th1 cells could paly an important role in the CRSwNP if sinonasal chronic inflammation is induced by SAGs.

Asbestosis is the disease of pulmonary fibrosis caused by the inhaled asbestos fibers, and could be diagnosed clinically, in the case of exposure history to asbestos is proved, by clinical symptoms of dyspnea or dry cough, physical examonation findings, and the radiographic features. But many othder inorganic dusts would show similar findings in the chest radiogram and sometimes the exposure history is obscure, so for the exact diagnosis of asbestosis lung biopsy is needed. In Korea, there have been some reports of survey in the workplace where asbestos is handled or of asbestos related diseases. This is a case report of asbestosis with accompanying pleural plaques, who had the occupational exposure to asbestos for 30 years and the consistent clinical, radiographic and pathological findings in the lung tissue obtained by the videoscope assisted thoracoscopic biopsy(VATS).

Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.
