초고속 통신망이 발달함에 따라 대기업은 물론, 학교와 중소기업에도 네트워크로 연결되어 업무 및 학습과 행정업무를 처리하고 있다. 인터넷을 이용한 재택근무, 재택교육 등이 발달하고 있는 시점에서 안정적이고 효율적인 네트워크환경을 제공하기 위해서는 네트워크상에 존재하는 다양한 자원들을 모니터링하고 제어하는 네트워크의 관리의 개념이 필요하게 되었다. 하지만, 대부분의 기업체나 학교에서는 구축비용측면에서 이를 투자하기를 꺼려하고 있다. 이에 본 논문에서는 중소기업 및 학교업무에서 일반적으로 사용되고 있는 MRTG(Multi Graphic Rotor Grapher)를 연계하여 웹을 이용한 손쉽게 망을 관리할 수 있는 툴을 perl을 이용하여 구현하였다. 장애의 대부분이 네트웍 자원관리와 실시간 로그관리를 이용할 경우 대부분의 장애를 미연에 방지할 수 있다는 점에 착안하여 텍스트를 처리함에 있는 탁월한 기능을 가진 perl을 이용하여 로그처리 데몬프로그램을 작성하였고, 자원관리와 이력관리를 위해서는 MySQL을 이용하였다.

코로나19 팬데믹으로 사회적 거리 두기가 확산됨에 따라 원격근무가 확산되면서 정부기관에서도 지난 3월부터 재택근무가 시작되어 현재도 일정 수준을 유지하고 있다. 따라서 비대면 시대의 원격근무 본격적인 확산에 대비해, 정보시스템 성공모형과 기술수용모형을 기반으로 정부기관에서 재택근무 시 필수적으로 사용하고 있는 정부원격근무서비스인 Government Virtual Private Network의 품질요인이 이용자 만족도에 미치는 영향 등을 분석하여 개선방안 마련에 기여하고자 한다.

Background: Despite the benefits of home oxygen therapy in patients suffering chronic respiratory failure, previous reports in Korea revealed lower compliance to oxygen therapy and a shorter time for oxygen use than expected. However, these papers were published before oxygen therapy was covered by the national insurance system. Therefore, this study examined whether there were some changes in compliance, using time and other clinical features of home oxygen therapy after insurance coverage. Methods: This study reviewed the medical records of patients prescribed home oxygen therapy in our hospital from November 1, 2006 to September 31, 2008. The patients were interviewed either in person or by telephone to obtain information related to oxygen therapy. Results: During study period, a total 105 patients started home oxygen therapy. The mean age was 69 and 60 (57%) were male. The mean oxygen partial pressure in the arterial blood was 54.5 mmHg and oxygen saturation was 86.3%. Primary diseases that caused hypoxemia were COPD (n=64), lung cancer (n=14), Tb destroyed lung (n=12) and others. After oxygen therapy, more than 50% of patients experienced relief of their subjective dyspnea. The mean daily use of oxygen was 9.8${\pm}$7.3 hours and oxygen was not used during activity outside of their home (mean time, 5.4${\pm}$3.7 hours). Twenty four patients (36%) stopped using oxygen voluntarily 7${\pm}$4.7 months after being prescribed oxygen and showed a less severe pulmonary and right heart function. The causes of stopping were subjective symptom relief (n=11), inconvenience (n=6) and others (7). Conclusion: The prescription of home oxygen has increased since national insurance started to cover home oxygen therapy. However, the mean time for using oxygen is still shorter than expected. During activity of outside their home, patients could not use oxygen due to the absence of portable oxygen. Overall, continuous education to change the misunderstandings about oxygen therapy, more economic support from national insurance and coverage for portable oxygen are needed to extend the oxygen use time and maintain oxygen usage.

Recent changes in health care environment including aging population and prevalence of chronic disease encourage the adoption of new innovative technological solutions including wearable vital sensors, wireless networks, and smart phone. In this paper, we present an effective at-home lifestyle monitoring system that can be used for self-management and health intervention of patient himself in the Management-by-Exception perspectives. We implemented the filtering and queuing algorithms as a preprocessor of monitoring system to enhance efficiency of proposed system, and the effective UX design for self-management of patients themselves. The 94,467 actual clinic data was used to test the efficiency of the proposed system. As as a result, 64.8% of the incoming vital data was identified to be filtered out.

With the renewed definition of "office". it's function and role has been reduced. Therefore. home oofices are beginning to draw people's attention. Office within the home is called SOHO (Small Office Home Office). SOHO has become possible with the development of information and telecommunication network technology. Recently. companies are adopting the SOHO system along with the trends of business restructuring. The SOHO offers workers to enjoy more flexible work time and enhance concentration thus improving jop efficiency. Companies will be able to cut down on fixed expenses and increase productivity. In addition. such working conditions will contribute to relieve traffic and environmental problems and furthermore it will make it possible to take advantage of potential workforce of women. the elderly and the handicapped. "Home Office" is expected to be one of the prevailing work system in the near future. Therefore. it is all the more important to study design problems including space design and furniture arrangement in order to improve work efficiency and provide a creative working environment. Moreover. architects and interior designers as well as experts on related fields such as information network. telecommunications. management and employment should continue to carry out joint researches for reasonable home office furniture and environment design.nd environment design.

This paper is for the a study on home healthcare system for a patient using SAW Tag. This system is useful when there's a patient in home. Many patients are wounded in restroom. But restroom is very private place and nobody want to be disturbed here. The place where the patient is most injured in the house is the toilet, and it is the point where the privacy of the individual should be kept and the patient's condition should be checked and cope with in case of emergency. And using saw tag, we can calculate position and ID through reflected rf signal. Therefore we propose a general home healthcare system. The management system utilized a seat bed system to monitor at-home patients. The system mounts a bio-signal measuring unit on a toilet seat, measures a bio-signal from the bio-signal measuring unit, and the measured bio-signal is transmitted to the main server through the user's smart phone. With proposed system, we can expand operation area to silver town where many patients are cared. In this paper we developed sensor system and saw tag positioning system and showed the result.

In the home health management system, we often face the situation to handle biological signals that are frequently measured from normal subjects. In such a case, it is necessary to decide whether the signal at a certain moment is normal or abnormal. Since ECC is one of the most frequently measured biological signals, we describe algorithms that detect QRS-complex and decide whether it is normal or abnormal. The developed QRS detection algorithm is a simplified version of the conventional algorithm providing enough performance for the proposed application. The developed classification algorithm that detects abnormal from mostly normal beats is based on QRS width, R-R interval and QRS shape parameter using Karhunen-Loeve transformation. The simplified QRS detector correctly detected about 99% of all beats in the MTT/BIH ECG database. The classification algorithm correctly classified about 96% of beats as normal or abnormal. The QRS detection and classification algorithm described in this paper could be used in home health management system.

Background : Although home oxygen therapy in hypoxemic patients with chronic lung disease has been increasing over the decade in Korea, the present state has not been known well. This study was done to know the situation of home oxygen therapy in a Korean university hospital. Methods : Between January 1, 2000 and August 31, 2003, 86 patients prescribed home oxygen therapy by the pulmonary physicians of Asan Medical Center were investigated using their medical record and questionnaire. Results : Patients (52 men, mean age of 61 years) with home oxygen therapy were increasing by every year. Underlying diseases were COPD (n=29), tuberculous destroyed lung (n=18), bronchiectasis (n=15), ILD (n=12), and others. Baseline $FEV_1/FVC$, FVC, and $FEV_1$ of patients were $58.4{\pm}25.2%$, $54.5{\pm}17.1%$ of predicted, and $41.7{\pm}20.6%$ of pred. Mean oxygen flow was 1.5 L/min and mean duration per day was 14.5 hours. During therapy, mean $PaO_2$ values have increased from 51.2 to 77.7 mm Hg and $PaCO_2$ values have increased from 47.5 to 49.6 mm Hg. Only 16.5% of the subjects were monitored by visiting nurses or pulse oximeter. Three year survival rate was 56.6% and hypercapnic patients showed better prognosis. Conclusion : The patients with home oxygen therapy were increasing yearly and a part of them were monitored. The hypercapnea respiratory failure patients would have better prognosis.
