  • Existing studies on the UAV (Unmanned Aerial Vehicle)-based CPS (Cyber Physical System) environment lack forest fire monitoring and forest fire reconnaissance using real-world UAVs. So, it is necessary to monitor forest fires early through CPS based on real-world UAVs with high reliability and resource management efficiency. In this paper presents an MFG (Misstion File Generater) that automatically generates a flight path of an UAV for forest fire monitoring in a CPS environment. MFG generates flight paths based on a hiking trail with a high fire probability due to a true story of an entrant. We have confirmed that the flight path generated by MFG can be applied to the UAV. Also, we have verified that the UAV flies according to the flight path generated by MFG in simulation, with a negligible error rate.

  • In Jang-Sang theory, ‘Sang’ indicates ‘Hyung Sang’. The internal organs appear it's shapes(Hyung Sang) outward. ‘Hyung Sang’ is concept that was used on 「the book of changes」(周易) and 「Nei Ching」(內經) to means a thing's shapes and conditions. ‘Hyung’ is the shape, an organization composing a thing and ‘Sang’ is the symptom, an essence(a seed) immanenting a thing. To observe Hyung Sang, it have to apply the principle that ‘the sky and man correspond each other(天人相應)’. Usually ‘Hyung’ appears as shapes and ‘Sang’ appears as colors and conditions. Diagnosis on the basis of Hyung Sang put first the external expression of the five Jang six Bu organs and Jung-Ki-Shin-Hyul(精氣神血). So a doctor has to unite shapes, colors, pulse and symptoms(形, 色, 脈, 症) when diagnosis a patient. The theory of Hyung Sang includes the basic theories of the oriental medicine, the theory for Yin-Yang and the five element(陰陽五行論), organ picture(Jang-Sang), meridians(經絡學說), the five circuit phases and the six atmospheric influences(運氣學說), physical constitution(體質學說). I think that treatment based on Hyung Sang is shown the essence of the oriental medicine well. In the future, I think, we need to study more about the theory of Hyung Sang.

  • In this work, we analyzed the viscoelastic characteristics of electrochemically polymerized polypyrrole(PPy) thin film in various electrolyte solutions, $Na_2SO_4,\;Na_2CO_3$ and SDS + $NaClO_4$, using QCA. The characteristics of redox reaction of electrochemically polymerized PPy thin film for 180 sec in each electrolyte, was investigated in 0.1 M $NaClO_4$ electrolyte solution by cyclic voltammetry method. We used one side of quartz crystal electrode as a working electrode and measured the resonant frequency, resonant resistance and current as analytical parameters. As the results, we suggest that electrochemically polymerized PPy thin film in various electrolyte solutions shows tendency changing from elastic characteristics to viscoelastic one in the order of $ClO_4{^{-}}\;+\;DS^-,\;SO_4{^{-2}}$ and $CO_3{^{-2}}$.

  • Using dried sludge as a secondary fuel of a coal-fired power plant is proposed as an alternative option for sludge disposal. Because elemental contents of sludge are different from those of coal, different levels of acidic gas emissions are expected from the co-combustion of sludge with coal. In this study, sludge samples were obtained from 7 sewage treatment plants in Korea. Each sludge sample was combusted together with coal in a lab-scale combustor, and the concentrations of nitrogen oxides ($NO_x$), sulfur dioxide ($SO_2$), hydrogen chloride (HCl), chlorine ($Cl_2$) in the flue gas were analyzed. Compared to the combustion of coal only, $NO_x$ concentration was slightly higher in the flue gas from the co-combustion of coal and sludge. $SO_2$ emission increased with the combustion of sludge due to the higher content of sulfur in sludge than in coal. For most of the tested samples, the concentrations of HCl and $Cl_2$ were varied depending on the chlorine content in the sludge sample.

  • US Army Found Five Lessons For the Urban Operations After Implemented Offensive Operations in Mosul, Iraq for the First time in the 21st Century. Based on these lessons the US Army Adds Spur Preparing For Future Megacity Operations Such as Weapon System, Warfighting Concept, Structure and etc. Korean peninsula experiences rapid Urbanization, so the Megacities are also Expected to Increase by this trend. So the ROK army also need to Benchmark the US Counterpart, so that the Organization needs to prepare following Elements. First, Establishing Collective Intelligence Platform for uture Megacity ops. Second, force Builing Optimized for the Megacity Operations(Warfighting Concept, Weapon System, Structures), Lastly, Establishing Megacity Synthetic Training field. By Preparing so, ROKA can Assure its Success in Future Warfare.

  • The poly(vinyl alcohol) $(PVA)/AgCF_3SO_3/Al(NO_3)_3$ electrolyte membrane was fabricated to prepare for highly permeable facilitated olefin transport membrane, compared with poly(vinylpyrrolidone) $(PVP)/AgCF_3SO_3/Al(NO_3)_3$ complex. In order to examine the characteristics of $PVA/AgCF_3SO_3/Al(NO_3)_3$ membrane, we used the analytical methods such as SEM, FT-IR, and FT-Raman. The best separation performance was observed at the mole ratio of 1 : 1 : 0.01 $PVA/AgCF_3SO_3/Al(NO_3)_3$ among various $Al(NO_3)_3$ concentration. As a result, the selectivity was 12 and mixed-gas permeability was 3.5 Barrer. Furthermore, the selectivity and permeability remained constant for up to 115 h.

  • Separation of $SO_2$ from the flue gases of fossil fuel power plants are important issue because of its strong environmental impact. Industrially, $SO_2$ is being removed with a slurry of limestone, lime or aqueous caustic soda. However, these scrubbing processes possess several drawbacks such as the generation of huge amount of wastewater and the production of metal salts. Recently, ionic liquids have gained increasing interest as an absorbent for acid gas, $CO_2$ and $SO_2$. In this review, we have introduced the recent progress of ionic liquids as a $SO_2$ absorbent.

  • The Foot drop is led by the conditional palsy of dorsal flexor according to some causes. In this case, it is caused by peroneal nerve palsy. It brings the difficulty in waking and standing up. We observed 2 cases of patient with Foot drop. Two patients were treated by the same method and treatment was performed by means of electroacupuncture(2-4Hz frequency, intensity was adjusted so that localized muscle contraction could be seen). As the result, symptoms are improved.

  • 1. Objectives: The purpose of this study is to find out the growth pattern according to Sasang Constitution. 2. Methods: One hundred forty seven students in the first grade of high school were classified into three groups(So-yangin, So-eumin, Tae-eumin) by QSCC II. We obtained the growth distance curve and growth rate, annual increment based on the Health Record according to Sasang Constitution. Health Record ranged from the first grade of the elementary school to the first grade of high school. And we calculated the Body mass index(BMI) and Mid-parential height(MPH). 3. Results: In case of Male, So-eumin and Tae-eumin showed linear growth patterns, but So-yangin showed rapid growth from 13 to 14. In case of Female, all of the groups showed similar growth pattern. But Tae-eumin showed a more growth from 8 to 9 than So-yangin groups. 4. Conclusions: Growth Pattern seemed to be different according to Sasang Constitution.
