In modern society, human and social damages caused by natural disasters and frequent disaster accidents have been increased year by year. Prompt access to dangerous disaster sites that are inaccessible or inaccessible using state-of-the-art Earth observation equipment such as satellites, drones, and survey robots, and timely collection and analysis of meaningful disaster information. It can play an important role in protecting people's property and life throughout the entire disaster management cycle, such as responding to disaster sites and establishing mid-to long-term recovery plans. This special issue introduces the National Disaster Management Research Institute (NDMI)'s disaster management technology that utilizes various Earth observation platforms, such as mobile survey vehicles equipped with close-range disaster site survey sensors, drones, and survey robots, as well as satellite technology, which is a tool of remote earth observation. Major research achievements include detection of damage from water disasters using Google Earth Engine, mid- and long-term time series observation, detection of reservoir water bodies using Sentinel-1 Synthetic Aperture Radar (SAR) images and artificial intelligence, analysis of resident movement patterns in case of forest fire disasters, and data analysis of disaster safety research. Efficient integrated management and utilization plan research results are summarized. In addition, research results on scientific investigation activities on the causes of disasters using drones and survey robots during the investigation of inaccessible and dangerous disaster sites were described.

우리나라의 화재는 연간 3만 건이 넘는 수준으로 알려지고 있으며 이중 방화로 인한 화재건수는 매년 조금씩 증가하고 있다. 화재 중 방화의 비율은 약 11~12%정도로 추정하고 있으며 화재로 인한 인명피해도 연간 약 2,200명 수준이다.

본 논문에서는 철관이 들어있는 건축물의 기초를 대용접지극으로 활용하기 위해 콘크리트의 전기적 특성에 관해서 기초적 검토를 하였다. 철근이 들어있는 몰탈블록 모형과 콘크리트블록 모형을 제작 후 접지저항 측정 결과에 따르면, 철근의 수량에 의한 접지 저항값과 대지저항률 보다 블록의 저항율에 의한 접지 저항값이 크게 영향을 받는 것을 알 수 있었다. The electrical characteristics of concrete block including a reinforcing rod in the foundation of the housing was fundamentally reviewed. It was tried to apply the substitutional earthing electrode in the foundation of the building. In order to identify the difference in the earthing resistance between mortar block and concrete block model, those models including a reinforcing rod in their inside were prepared and investigated for the earthing resistance. In results, the earthing resistance was largely affected by the block's resistivity compared to the change of resistance in reinforcing rods and the ground resistivity.

건축물의 기초를 구조체접지 및 대용접지극으로 활용하기 위한 기초실험으로 모형블록의 저항률 특성에 관해 검토하였다. 콘크리트와 몰탈의 모형블록을 제작 후 상온과 함수 상태에서 저항률을 측정하였으며, 저항률을 저감시키기 위해 접지저항 저감제를 혼합한 블록을 제작 하여 비교 하였다. 블록의 저항 값은 블록 저항률에 의해 가장 많은 영향을 받으며, 블록 저항률이 동일하거나 유사한 값일 때 대지저항률 값의 차이만큼 접지저항 값의 차이가 발생하였다. This study analyzed the resistivity characteristic of model block to make the good use of structure grounding and substitution grounding electrode base of building. After making the model block of mortar and concrete block, it measured resistivity in hydrous condition and dry condition and compared with the blocks that is mixed earth resistance lowering agent to decrease resistivity. The resistance value of block accepted much influence by block resistivity. When the block resistivity was same or similar value, the value of soil resistivity has occurred as different as the value of grounding resistance.

We investigated the effects of feeding rate on the growth performance of growing and sub-adult olive flounder Paralichthys olivaceus, and the optimum feeding rate at high water temperature (25-31°C). In experiment I, two replicated groups of fish (113 g) were fed a commercial diet (CD) at rates of 0, 0.7, 1.2, 1.7, 2.2, and 2.4% (satiation) body weight (BW) per day for 4 weeks. In experiment II, two replicated groups of fish (313 g) were fed a CD feeding rates of 0, 0.3, 0.5, 0.7, 0.9, and 1.0% (satiation) BW per day for 4 weeks. In experiment I, the weight gain (WG) and specific growth rate (SGR) of fish fed at 0.7 and 0.9% BW per day was significantly higher than that of unfed fish (0%) and fish fed at 0.3, 0.5, and 1.0% (satiation) BW per day. In experiment II, the WG and SGR increased significantly as feeding rate increased from 0 to 2.2% BW per day, but decreased in the satiation group (2.4%). Broken-line regression analysis of WG showed that the optimum feeding rate of growing and sub-adult olive flounder were 1.98% and 0.55% BW per day, respectively, at the high water temperature.

A 3×3 factorial study was conducted to investigate the effects of dietary protein and lipid levels on the growth, feed utilization and innate immunity of red seabream Pagrus major. Nine diets consisting of three protein levels (42%, 46% and 50% crude protein) and three lipid levels (10%, 14% and 18% crude lipid) were formulated. Triplicate groups of red seabream were fed the experimental diets to apparent satiation (5-6 times a day, from 08:00 to 18:00 h at 2-h intervals) for 10 weeks. At the end of the feeding trial, the weight gain and specific growth rate of fish fed P46L14 (46% protein and 14% lipid), P50L10 (50% protein and 10% lipid) and P50L14 (50% protein and 14% lipid) were significantly (P<0.05) higher than those of fish fed P42L18 (42% protein and 18% lipid). The feed conver-sion ratios (FCR) of the fish were affected by dietary lipid levels (P<0.039), but not dietary protein levels. The FCR tended to increase with increasing dietary lipid levels from 10% to 18% with the 46% and 50% protein levels. The weight gain, protein efficiency ratio, specific growth rate, feed intake and survival of fish were not affected by either dietary protein or lipid levels. Myeloperoxidase activity in the group fed P50L14 (50% protein and 14% lipid) was significantly higher than that in the group fed P42L10 (42% protein and 10% lipid) or P50L18 (50% protein and 18% lipid). However, the myeloperoxidase activity of fish was not affected by either dietary protein or lipid level. The fish fed P46L14 (46% protein and 14% lipid) and P46L18 (46% protein and 18% lipid) showed significantly higher superoxide dismutase activity than did the fish fed P46L10 (46% protein and 10% lipid), P50L10 (50% protein and 10% lipid) of P50L18 (50% protein and 18% lipid). In conclusion, the optimum protein and lipid levels for the growth and feed utilization of juvenile red seabream were 46% and 14%, respectively, and the optimum dietary protein to energy ratio was 27.4 g/MJ.

We performed three sets of feeding trials to establish the optimal feed size (Exp-I), stocking density (Exp-II), and dis-solved oxygen level (DO) (Exp-III) for olive flounder Paralichthys olivaceus. In Exp-1, four replicate groups of fish (53.6±0.9 g) were fed commercial diets with three particle sizes (small, medium, and large). In Exp-II, fish (30.0±0.1 g) were reared at four stocking densities (1.8, 3.5, 5.3, and 7.1 kg/m3). In Exp-III, fish (187±1.48 g) were reared under two different DO levels (2-3 and 6-7 mg/L). In Exp-I, fish fed the large-particle diet gained significantly more weight and had a lower feed conversion ratio than fish fed the small- and medium-particle diets. In Exp-II, fish reared at 1.8 and 3.5 kg/m3 gained slightly more weight and had lower feed conversion ratios than fish reared at 5.3 and 7.1 kg/m3, although these differences were not significant. In Exp-III, negative effects were observed in the low DO groups. Therefore, under our experimental conditions, the optimal feed particle size, stocking density, and DO level for olive flounder were 9-9.4 mm, 3.5 kg/m3, and 6-7 mg/L, respectively.
