이태균(Tae-gyun Lee),박재민(Jae-min Park) 한국정보통신학회 2023 한국정보통신학회 종합학술대회 논문집 Vol.27 No.1

탄소중립 시대 수목은 도시의 유일한 탄소흡수원으로 중요성이 부각되고 있으며, 관련한 다양한 연구 및 국가적 인증제 도입 등이 논의되고 있다. 하지만 현재 도시공원에서 얼마나 많은 탄소를 저장하고 흡수하고 있는지에 관한 연구는 부족하다. 이에 본 연구에서는 대표적 도시공원 유형별(근린공원, 소공원, 어린이공원)로 탄소흡수량의 평균값과 영향 요인을 분석하고자 하였다. 수목 개체별 탄소흡수량은 I-Tree Eco를 활용하여 개체목 단위로 산출하였고, 유형 별 각 5개소를 대상으로 탄소흡수량을 분석하여 평균값을 도출하였다. SPSS를 이용하여 도시공원의 유형별 탄소흡수량에 영향을 끼치는 요인을 상관분석하였다. 분석 결과 식재 밀도 및 식재 규격이 탄소흡수량에 높은 상관성을 보였다. 본 연구는 도시공원 유형별 평균적 탄소흡수량을 도출함으로써, 향후 탄소 저감설계 및 도시공원 관련 탄소중립 정책 기준 지표의 기초 자료로 의의를 가진다. The importance of urban trees as the sole carbon sink in the era of carbon neutrality has been highlighted, and various studies and national certification systems are being discussed. However, there is a lack of research on the amount of carbon stored and absorbed by urban parks. Therefore, this study aimed to analyze the average amount of carbon absorption and its influencing factors for representative types of urban parks (neighborhood parks, small parks, and childrens parks). The carbon absorption amount per tree was calculated using I-Tree Eco at the individual tree level, and the carbon absorption amount was analyzed for five parks of each type to obtain the average value. In addition, SPSS was used to perform correlation analysis on factors influencing the amount of carbon absorption by urban park type. The main factors affecting the carbon absorption amount in urban parks were found to be green coverage rate, tree species, and planting density. This study provides important basic data on the average carbon absorption amount by urban park type, which can be used as a basis for future carbon reduction design and the development of carbon neutrality policy standards related to urban parks.

국립공원은 주로 산악 지형 내 조성되어 있으므로 산사태에 의한 피해 가능성을 항상 내포하고 있다. 본 연구는 산사태 연구의 일환으로 국립공원 탐방로 내 위험 급경사지를 체계적으로 유지관리하기 위한 방안을 마련하는데 목적이 있다. 국립공원에 특화된 자체 체크리스트를 제작하였으며, 전국 19개 국립공원 183개소 급경사지에 대한 실태조사가 이루어졌다. 실태조사의 최종 목적은 위험 급경사지에 대한 안정화 대책을 마련하는 것으로 현장조사와 안정해석의 과정을 거친다. 일부 급경사지에서는 위험성 판단을 위해 지상라이다 등 특수 장비를 이용한 조사를 시도하였다. 중장기 정비계획을 위한 투자우선순위 공식을 개발하였으며, 현장자료를 이용한 순위 및 위험등급을 산출하였다. 최종적으로 위험 급경사지의 향후 체계적인 관리를 위해 “국립공원 급경사지 유지관리시스템”을 개발하였으며, 모든 현장자료들은 시스템 내 DB화 되었다. National parks, which are located mainly in mountainous areas, are always at risk of damage by landslides. The goal of this study is to establish a method for systematically maintaining hazardous steep slopes along trails in national parks. We produced a checklist suitable for each of the 19 national parks nationwide and investigated 183 slopes. The aim of these investigations is to recommend appropriate slope-stability countermeasures, including field investigations and stability analysis. We made preliminary investigations at specific sites, evaluating the slope hazard using specialized equipment such as terrestrial LiDAR. An investment priority formula was developed, and ranking and hazardous grades were calculated as part of a long-term maintenance plan. Finally, to systematically manage dangerous slopes and to house all the field data within one system, we developed the “Slope Maintenance System in National Parks” based on web server that can show various information for slopes.

In relation to pollution load, 166 towns and cities set the following optimum number of livestock, according to cultivated area, the amount of fertilizer ingredient for crops and wastes. According to the analysis of the total capacity for waste based on cultivated area and fertilizer requirement, N was 279,884 M/T, P2O5 140,464 M/T and K2O 182.559 M/T. Total amount of nutrient production according to the number of livestock were 222,331 M/T N, 64,716 M/T P2O5 and 86,670 M/T K2O, which are 86.7%, 53.6% and 52.7% of the fertilizer requirment. It is estimated that 45 regions showed an overload capacity of fertilizer per hectare in N, 11 regions in P2O5 and 13 regions in K2O, The converted optimum number of livestock was 13,415,000 Livestock Unit (LU).

Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.

PLC programming languages are various from LD(Ladder Diagram), to SFC(Sequential Function Chart), IL(Instruction List) and FBD(Function Block Diagram). Because they use I/O signals of sequence control, it is very difficult to identify operation status in a glance. Consequently, operators cannot troubleshoot easily when problem occurs. In this article, to supplement those disadvantages, an Automatic Supply Machine, the manufacturing machine of rubber roller that yields printer paper, was used for experiment and analysis. Firstly, PLC program was constructed for the operation of Automatic Supply Machine and it was stored in PLC memory. Secondly, a program was written in Visual Basic Program to monitor I/O signals of PLC program. Thirdly, it was compiled to make an executive program and the executive program was placed on 'Desktop'. A new programming method was proposed to perform smooth control and effective operation by monitoring Automatic Supply Machine operation status and troubles with communication between PLC and a computer.

Purpose: This study was peformed to investigate whether the free to total PSA ratio(F/T PSA ratio) offers a better discriminant for the detection of patient with prostatic cancer(CaP) and those with benign prostatic hyperplasia(BPH) than serum total PSA alone. Materials and Methods: From September 1996 to February 1999, free and total PSA levels were measured on frozen sera samples of 154 men with BPH and 46 with CaP using immunoradiometric assay. Results: In all subjects, the mean total PSA was significantly higher in CaP group(72.57±66.58ng/ml) than BPH group(3.12±4.10ng/ml). The mean PSAD was significantly higher in CaP group(1.64± 1.86) than BPH group(0.08±0.01). The mean F/T PSA ratio was significantly lower in CaP group(0.19± 0.07) than BPH group(0.30±0.13). Among 41 subjects whose total PSA were between 4-20ng/ml, the mean PSAD was significantly higher in CaP group(0.37±7.16) than BPH group(0.17± 0.07), but the mean F/T PSA ratio was not significantly different between CaP(0.19± 0.10) and BPH group(0.25±7.13). By comparing the sensitivity and specificity of total PSA alone, PSAD and F/T PSA ratio on receiver operating characterislic (ROC) Cutie in all subiects and subiects with total PSA between 4-20ng/ml, F/T PSA ratio had no superiority than total PSA alone and PSAD for discrimination between CaP and BPH. Conclusions: We suggest that the F/T PSA ratio is not superior to total PSA alone and FSAD in the detection of prostatic cancer, and further evaluation of the usefulness of F/T PSA ratio should be required.

In this study selected Koreasat 3, which uses the Ku-band(14㎓/12㎓) frequency, and analyzed the beacon signal level data according to the rain rate from June to August in 2001. Then to provide analysis, the experimental data was compared with that obtained using typical rain attenuation models, such as the ITU-R model, the SAM model and the Global model, which have previously been used in satellite communication systems. Also, this study analyzed predicted area path diversity gain on the basis of the path of Daejeon-Koreasat 3 in order to compensate excess attenuation caused by rain, and estimated link budget by hour rate on the basis of the ITU-R model. Establishing the reliability of path diversity gain and link budget achieved by this study may be greatly used as a basic material to design satellite communication system in the future. Furthermore, according to methods to be applied, it could be utilized to construct microwave communication network or broadcasting network on the ground.
