Purpose: This study was to present home-care cases of gangrene sores or prevalent diseases using fake energy salt (FES) water containing energy. Methods: The health functional foods used for disease management were FES Water. Each product was Myeongil Leaf powder, dried yeast, propolis, fermented organic calcium, and royal jelly. Changes were investigated after taking this food. Some of them were combined with hospital treatment, and most of them were experienced by patients at home while managing the affected area. Results: One patient with high fever swine flu, who was treated in a hospital, had a fever dropping to the normal range in 2 hours, and one patient with a leg fracture healed in about six weeks, and one patient had bone adhesion in 2 weeks. Patients with rhinitis recovered after taking FES, and the intraocular pressure of patients with damaged retinopathy fell from 40 mmHg to 20 mmHg after taking FES. One patient with postpartum sequelae was said to have improved their aching limbs four days, and a Covid-19 confirmed patient admitted to the hospital was discharged ten days after starting taking FES during treatment. The size of the gangrene sores in 19 subjects initially ranged from 1 to 7 cm. Most of them were alleviated or healed by continuing to manage them at home with health functional food intake and FES for two weeks to a year. Conclusions: The above results are personal experiences and health functions, such as fake energy salts. It was possible to recognize that food was helpful for health promotion, but no final medical diagnosis was made.

In this paper, the proposed watermark algorithm is based on energy distribution of the subband coefficients in the frequency domain and edge of the original image in the spacial domain. Out of these information, the KeyMap which decides the embedded position of watermark is produced. And then the binary watermark is embedded into the wavelet coefficient of LL3 subband using KeyMap and LFSR(Linear Feedback Shift Register).

진공 시스템의 기저상태를 지배하는 것은 대부분의 경우 용기 내면에 수십 단원자 층 정도로 흡착되어 있는 물이다. 용기 압력이 10-9 mbar 대가 될 때까지는 잔류기체의 90% 이상이 수분이고 압력을 10분의 1로 떨어뜨리려면 10배의 시간이 더 필요하다는 소위 1/t 법칙은 광범위한 흡착에너지를 가지는 물분자의 표면방출 특성으로 잘 설명되어진다. 용기가열 등 적극적인 표면처리를 하지 않고 전형적인 압력변화 양상은 그대로 유지하면서 절대적인 시간을 줄이는 가장 직접적인 방법은 물 배기속도를 가능한 한 높이는 것이지만 대부분의 고진공 펌프들에서 물배기속도만 더 증가하도록 만드는 것은 쉽지 않다. 크라이오 워터펌프(CWP: cryo-water pump)는 바로 이런 고민을 제대로 해결할 수 있는 유일한 실용적인 방안이라고 말할 수 있다. 다른 기체분자들의 배기는 일단 염두에 두지 않고 물배기만을 열심히 해서 배기시간을 단축하고 도달 진공도를 낮추는 것을 목표로 하는 장치가 CWP이다. CWP는 모든 기체에 반응하는 정통적인 크라이오 펌프에 비해 훨씬 간단하고 저렴하게 만들 수 있으면서도 진공 시스템에 큰 영향을 미칠 수 있지만 그동안은 물배기의 필요성에 대한 인식이 미흡하고, 또 부수적이고 추가적인 비용이 드는 것으로 생각되어 주목을 받지 못했지만 디스플레이와 반도체 산업을 필두로 물분압을 낮추고 생산수율을 높이는 것에 점점 더 관심이 높아지면서 CWP에 대한 수요도 높아지고 있다. CWP의 물배기는 아주 단순한 응축현상에 의존하므로 물리적으로 이해하고 성능을 예측하는 것이 직관적이지만 사용용도에 따라 물 이외의 기체분자들은 잘 통과시키면서 물배기는 최대화하는 최적설계가 요구되거나 터보분자펌프(TMP)와 같이 이질적인 고진공펌프와 조합하여 사용하는 경우 기체 온도 의존성을 고려해야 하는 등 까다로운 점이 있다. 본 보고에서는 CWP+TMP로 구성된 복합진공배기시스템을 설계하면서 CWP만의 물배기성능과 복합 시스템의 물 및 알곤 배기성능을 예측하고, 두 펌프의 상호관계에 대해 분석하며, 실제 만들어진 복합배기시스템을 사용하여 실험적으로 구한 물 및 알곤 배기속도 측정결과에 대해서도 간단하게 논의하려고 한다.

Grid(pipe network) design is an important element of Smart Water Grid, which essential to estimate hydraulic parameters such as the pressure, friction factor, friction velocity, head loss and energy slope. Especially, friction velocity in a grid is an important factor in conjunction with energy gradient, friction coefficient, pressure and head loss. However, accurate estimation friction head loss, friction velocity and friction factor are very difficult. The empirical friction factor is still estimated by using theory and equation which were developed one hundred years ago. Therefore, in this paper, new equation from maximum velocity and friction velocity is developed by using integration relationship between Darcy-Weisbach's friction head loss equation and Schlichting equation and regression analysis. To prove the developed equation, smooth pipe data areis used. Proposed equation shows high accuracy compared to observed data. Study results are expected to be used in stability improvements and design in a grid.

As an energy network infrastructure, which is capable of integrating energy related services such as AMR/AMI, Smart Grid, and Smart Water Grid, the Smart Utility Network (SUN) enables a paradigm shift from user-oriented networks to device-oriented networks. The SUN has some similarities to sensor networks in application and network requirements. Therefore it is required to investigate and analyze thoroughly existing related work in advance to design new network protocols for SUN. In this paper we analyze service requirements and design considerations for SUN and then present a design guideline of new network protocols for SUN by investigating existing low power protocols, data aggregation methods, and in-network storages.

The reclaimed land has peculiar characteristic of nature environment unlike midtown or inland and also, in comparison with inland, has bad weather condition, such as low temperature, strong wind, excessive sunshine, and moisture involved in a salt. Therefore the case of developing water front needs understanding characteristic of weather environment mused by reclamation in detail and proper development and organized maintenance. If development which doesn't investigate topographic and climate characteristic sufficiently is drove ahead, a rise of expense for energy and maintenance is going to be mused by deteriorating weather environmental, occurring a flaw of facility and calculating inaccurate capacity of facility. We looked into the weather state and drew up the standard weather data of the newport area in Busan which is reclaiming and developing now. In this research at the base qf the standard weather data, we calculate the dynamic peak loads for commerce, business and residence and then we utilize the results of the load calculation as basic information to determine facility capacity in the rear city of the newport area.

Groundwater and animal wastes are typical example which are underutilized resources than their value in agriculture. This paper was to investigate the actual patterns of utilization of water curtain for greenhouses and methane gas utilization from swine wastes in a view point of promoting more efficient use of alternative energy. The results from measurements can be summarized as follows : 1.It was estimated that the maximum heating load per l0a was around 23,2804/hr and the heating load at January showed 3.93X 1064 respectively for strawberry greenhouses with insulation by the water curtain. 2.The average heating cost of the greenhouse with water curtain system amounted to about 75,000 Won per l0a. This result suggested that the greater cultivated area provides less heating cost. 3.The operating volume was about 73 percent of the optimum size of the digester. The net available methane gas rates of the produced gas remained close to 62 percent, But the conventional and small size of the digester was maintained at a lower level of around 20 to 29 percent. 4.It appeared that major problems of biogas production system were required to maintain the temperature of the fermentation above ambient temperature and the optimum volume of digester.

스마트워터그리드(Smart Water Grid; 이하 SWG)란 현재 직면에 있는 물 부족, 물 안보, 물 복지 등 물에 대한 문제를 ICT 기술을 활용하여 물관리의 새로운 패러다임을 제시할 수 있는 융합 기술이다. 즉, SWG는 기존의 수자원 관리 시스템의 한계를 극복하기 위해 첨단 정보통신기술을 이용하는 고효율의 차세대 인프라 시스템으로 다양한 수원을 활용하고 물을 효율적으로 배분 관리 운송하여 수자원의 불균형을 해소하고, 첨단센서네트워크를 이용해 용수관리 전분야에 걸쳐 양방향 실시간으로 용수정보를 감시 대응하여 용수관리와 에너지 효율의 최적화된 메가시티(mega-city)에 적합한 지능형 물관리가 가능할 것으로 예상되는 시스템이다. 따라서 국토교통부 과제로 추진중인 SWG 연구단에서 개발한 스마트 워터 기술을 영종도 112 블록에 적용하여 지역주민의 물복지 향상 및 물 사용자에 대한 소비자 만족도를 높이는데 목적을 두고 데모플랜트를 구축 방안을 수립하였다. 영종도 112블록(인천 운서동 및 운북동 일원)은 인천 공촌정수장에서 해저관로를 지나 영종통합 가압장에서 가압 후 공항신도시배수지에서 물을 공급받고 있는 지역으로 면적은 $17.41km^2$, 인구는 약 17,000명, 물사용량 $8,000m^3$/일, 총관로연장 약 55km, 유수율이 겨우 73.2% 지역이다. SWG 적용성 평가를 위해 영종도 112 블록에 유수율 제고 및 운영비용 저감을 목적으로 데모플랜트를 구축하였다. 스마트 계측을 위해 스마트미터 469개(15~20mm), 디지털미터 172개(25~200mm), 누수유무센서 1개소, 다항목 수질측정기 1개소, 유량계 3개소, 수압계 5개소, AMI 시스템 641개 및 물효율 운영프로그램과 물정보 App서비스 기능으로 구성하였다. 물효율 운영프로그램은 실시간 수요량 예측, 배수지 운영에 따른 취수량, 송수량, 펌프 대수조합 및 운전스케줄링이 가능한 경제적 물공급 스케줄링, 관망상태 감시 및 제어(실시간 유량/수압 분석을 통한 누수분석) 기능이 탑재되어 통합운영센터에서 운영할 계획이다. 데모플랜트 운영을 통해 수자원의 효율적인 배분 및 공급, 유지관리 향상, 운영 비용 최소화 등의 결과를 바탕으로 신도시 및 기존도시의 물관리 정책수립에 활용할 수 있을 뿐만아니라 시간적 공간적 불균형 해소 및 물시장 발전에 크게 기여할 것으로 사료된다.
