2020년 7월 1일부터 공원일몰제가 시행되어 전국에 있는 미조성 공원이 지위를 상실하여 개인 사유지로서 개발이 가능하게 된다. 이는 애초에 개인에게 귀속된 토지를 공원으로 강제 지정하여 녹지를 유지하기 위함이었으나 개인의 재산권 침해 문제가 지속적으로 제기되어 왔고, 토지 소유자들의 권리를 인정하여 공원으로 지위를 해제하게 된 것이다. 서울시의 전체 공원 면적 $111.8km^2$중 $57.5km^2$가 미조성 공원이고 이 중 $55.1km^2$이 10년 이상 미집행 되어 2020년에 공원일몰제 시행 대상이다. 공원일몰제에 따른 난개발을 방지하기 위해 서울시는 토지 매입 예산을 책정하였으나 최근 과도한 부동산 가격 상승으로 인해 토지 보상비는 예산을 크게 웃돌 것으로 보인다. 때문에 서울시는 기존의 매입 기조를 수정해야만 한다. 따라서 본 연구에서 이에 대한 해결 방안으로 '수직 빌딩 숲(이하 빌딩숲)' 건축 보조금 지원을 제안하고자 한다. 빌딩숲은 토지 면적에 비해 높은 환경적인 효과를 보이며 기존 비용의 5%의 추가 비용으로 건축이 가능하다. 토지 가격과 녹지 유지의 필요한 정도를 위치에 따라 판단하고, 토지 매입 대신 건축 비용 보조를 통해서 환경적인 효과와 경제적인 효과를 동시에 도모할 수 있다. 따라서 이 연구는 특정 기준에 적절한 입지를 찾아 빌딩숲을 건축하는 것으로 공원일몰제의한 대안을 제시한다.

The purpose of this study is not only to widen and deepen the understanding of external environments of hairstyle but also to provide the basis of understanding and perspicacity as to the hairstyle which will be created under the influence of new music by contemplating distinctions between Glam Fashion and Punk Fashion of 1970s and by comparing and analyzing distinctions between Glam Hairstyle and Punk Hair Style of 1970s. As the method of this study, first of all four common factors, which are resistance, androgynous, beauty of ugliness and pursuit of pleasure through persona, were able to be ed from both Glam Fashion and Punk Fashion of 1970s, and then by using that factors as analyzing instrumental frame, the above two hairstyles were compared and analyzed through photographic materials in this study. According to the results of comparing and analyzing two hairstyles above, in Glam Hairstyle, the androgynous character is the most remarkable distinction. They tried to overturn the gender role by challenging the traditional color and form of hairstyle. In funk Hairstyle, the resistance is the most prominent distinction. They expressed their group identity resisting a pre-existing generation by putting on threatened and aggressive hairstyle.

This study improved construction and cost efficiency that are disadvantages of existing low vibration crackers(low vibration cracker, plasma, etc) and introduced cases of development and practical applications of Low vibration explosives(NewFINECKER) that minimizes blast vibration. The low vibration explosives(NewFINECKER) is suitable to Type-1 among standard blasting patterns of Ministry of Land, Transport and Maritime Affairs(MLTM) and delay blasting is possible. Moreover, the low vibration explosives improve construction and work efficiency while the level of vibration is shown to be about 60~70% of normal emulsion explosives. Additionally, this study suggested standard blasting patterns, the prediction equation of blasting vibration, and construction methods.

최근 기후의 급격한 변화 및 이상기후로 인해 전 세계적으로 가뭄의 발생빈도가 증가하고 있는 추세이다. 우리나라의 경우 지역·계절별 강수량의 편차로 인해 국지적으로 극심한 가뭄이 발생하고 있으며, 향후 피해는 더욱 증가할 것으로 예측하고 있다. 농업가뭄은 농작물 생육에 따른 수확량 및 수자원 이용에 직접적인 영향을 미치고 있으며, 농업수리시설물의 의존도가 높기 때문에 저수지의 대응능력과 농경지의 수리답 시설이 농업가뭄 대응을 위한 중요한 지표로써 활용되고 있다. 본 연구에서는 수리시설물의 가뭄대응능력과 평야부 농경지의 가뭄빈도를 이용하여 농업가뭄 취약성 평가를 수행하였다. 2015년 이후 매년 가뭄이 발생하는 충청남도 태안군을 시범지역으로 선정하였으며, 논 중심의 농업가뭄을 평가하기 위해 기상영향, 가뭄발생현황, 보조수원능력, 가뭄대응능력 4가지의 관련 항목을 선정하였다. 기상영향, 가뭄발생현황, 보조수원현황 항목은 계수화를 위해 데이터 속성 정보만을 이용하여 가중치를 산정하는 엔트로피 (Entropy) 방법을 적용하였으며, 가뭄대응능력 항목은 농업수리시설물과 농경지 평균 가뭄빈도 분석을 통해 점수화를 수행하였다. 본 연구의 결과는 지역별로 선제적인 가뭄대응 우선순위를 결정할 수 있고, 용수공급의 효율화 등 논 중심의 농업가뭄 대응을 위한 기초자료로써 활용될 수 있을 것으로 판단된다.

Generally there is a technical gap for the image data quality between from the satellite requirement values and from the users. After Cal/Val for KOMPSAT-3 had been done by Dec. 31, 2012, all requirements for KOMPSAT-3 image data quality have been validated, and then the normal operation of it started from Jan. 2013. In the normal period, the image data quality for the users has been defined and managed, and according to the result of it, the additional Cal/Val items have been doing. Cal/Val team and Processing team in KARI made the quality report (QR) for KOMPSAT-3 image data quality for the users, and have determined the quality level of KOMPSAT-3 product generated by Processing system (PMS; Product Management System) and managed the quality report for it. According to the result of the quality report, Cal/Val team defined six additional Cal/Val items, and has done five items of them and has been implementing the result of them into the Processing system.

Effects of nitrogen top-dressing method on quality of barley were evaluted over amount of 2 and 4 kg per 10a on volcanic ash soil in Japan under regrowth stage, productive tiller stage and heading stage. 55% milling time was longer by the amount of top- dressing, but that was not influenced by the times of top-dressing. And glassiness, whiteness, hardness and 8 minute- millng rate were not influenced by times and amounts of top-dressing. Crude protein rate of grain was increased by amount of nitrogen top-dressing, but that did not correlated with time of nitrogen top-dressing. Crude protein rate of grain was positively correlated with 55% milling time. But that did not correlated with whiteness of 8 minute-milled grain. 8 minute-milling rate was negatively correlated with whiteness of 8 minute-milled grain. There was no visible difference of protein matrix with scanning electron microscope in different nitrogen levels.

Purpose : Recently, clinical trials of steroid add-on therapy were reported with variable results in Kawasaki disease. We analyzed the clinical outcomes of patients at high risk of with Kawasaki disease(${\geq}4$ points of Harada score) treated by three commonly used different treatment regimens, with or without corticosteroids. Methods : Medical records of 96 children with Kawasaki disease treated with one of the threee regimens were reviewed retrospectively. Regimen 1 was aspirin(100 mg/kg/day) plus intravenous gamma globulin 2 g/kg single dose; regimen 2, aspirin(100 mg/kg/day) plus intravenous gamma globulin 1 g/kg single dose; regimen 3, regimen 2 plus prednisolone(2 mg/kg/day), followed by tapering two weeks and pulse therapy of methyl prednisolone performed in cases of retreatment. Also low dose aspirin was given in all three regimens for eight weeks after the acute phase. The cardiovascular and laboratory evaluations were performed on acute phase, immediate after acute phase, and subacute phase, eight weeks after treatment. Results : The frequency of coronary artery lesions and laboratory findings in the three different regimens were similar. The more rapid control of fever after treatment was noted in regimen 3. Furthermore the frequency of retreatment was decreased in regimen 3 compared to the other two regimens. Conclusion : Steroid add-on therapy showed some beneficial outcome compared to conventional treatment regimens. The role of steroid in the treatment of Kawasaki disease should be reassessed in systemic manner.

It is very important to track whether software is properly developed according to requirements. This study suggests a method to track requirements by using a tracking table. In this study, the tracking table indicates why such requirements are included by detailing the content of requests for proposals and proposals. The table also facilitates verification of the consistency between outputs and the integrity by having ID codes of each requirement mapped to each output. Furthermore, as this study was conducted, it was found that some factors were required to be added or supplemented to the outputs at the requirement gathering stage of MaRMI-Ⅲ v.4.0 methodology. Thus, this study seeks to present this additional result along with the enhanced tracking table. By verifying outputs, the tracking table presented in this study will help to reduce all kinds of risks and problems that may occur in software development due to the lack of management of requirements. In addition, the output of the requirement-gathering stage of MaRMI-Ⅲ v.4.0 methodology will be improved/supplemented according to the creation of tracking tables; this will increment the applicability of the MaRMI-III methodology.

일반적으로 가뭄을 해석하기 위하여 가뭄심도, 빈도, 피해면적 및 기간의 영향 등을 고려한 가뭄지수를 이용하며, 이러한 가뭄지수는 주로 지점자료 기반 지상관측자료를 활용하여 산정한다. 하지만 지점자료 특성상 미계측 지역에 대한 정확한 데이터 취득이 어렵기 때문에 미계측 지역에 대한 가뭄 분석의 한계가 발생한다. 다양한 계측기반의 지상센서들이 확충되면서 통계학적 기법기반 공간분포 개선방안을 제시하고 있지만, 정확한 가뭄평가 자료가 추가 및 개선되는 것이 중요하다. 본 연구에서는 원격탐사기술을 활용하여 지점자료의 한계를 극복한 격자기반의 공간정보를 표출함으로써 새로운 가뭄모니터링 방안을 제시하는 것을 목표로 한다. 이를 위해 지상관측자료로 가뭄을 판단하기 어려운 미계측 지역에 대한 가뭄 판단 및 예측 정확도 향상을 위하여 원격탐사기술을 활용한 공간정보 빅데이터를 구축하고자 한다. 미국 국립가뭄경감센터에서 제시한 식생가뭄반응지수 (VegDRI, Vegetation Drought Response Index)는 식생지수, 기상학적 가뭄지수, 지역적 특성을 반영한 생물물리학적 정보를 통합한 하이브리드 가뭄지수로 가뭄과 관련된 공간정보를 활용하여 가뭄을 판단하는 지표이다. VegDRI 산정을 위하여 ERA5의 격자기반 강수자료, MODIS 센서 기반 식생지수 등 격자기반의 공간정보를 수집하였으며, 전처리 모듈을 구축하였다. 또한, 기존 기상학적 가뭄지수인 표준강수지수 (SPI, Standardized Precipitation Index)와 비교를 통해 VegDRI의 국내 적용성을 평가하였으며, 국내 가뭄사례에 적용하여 적절한 가뭄 판단지표로써 활용할 수 있을 것으로 판단된다.
