  • As IoT technology has gained the attention all around the world, the development for various services of healthcare, smart city, agriculture, and defense based on IoT is in progress. However, it is likely that healthcare services based on IoT have a problem of being leaked of patients' biological information by a third party and that risks patients' lives. In this paper, an IoT health care service managing model based on location sensor is proposed, which secures the biological information of a patient and simplifies the procedure to process the treatment and administration steps by using the data resources sensed. Even when an emergency occurs, this proposed model can respond quickly using the location information of the patient, which enables the staff in the hospital to locate the patient in real time. In addition, there is an advantage to minimize the time and the process of care, because the location of the equipment for necessary treatment is possible to be instantaneously located with attached sensors.

  • Global warming-induced drought inflicts significant socio-economic and environmental damage. In Korea, the persistent drought in the southern region since 2022 has severely affected water supplies, agriculture, forests, and ecosystems due to uneven precipitation distribution. To effectively prepare for and mitigate such impacts, it is imperative to develop proactive measures supported by early monitoring systems. In this study, we analyzed the spatiotemporal changes of multiple evapotranspiration-based drought indices, focusing on the flash drought event in the southern region in 2022. The indices included the Evaporative Demand Drought Index (EDDI), Standardized Precipitation Evapotranspiration Index (SPEI) considering precipitation and temperature, and the Evaporative Stress Index (ESI) based on satellite images. The Standardized Precipitation Index (SPI) and SPEI indices utilized temperature and precipitation data from meteorological observation stations, while the ESI index was based on satellite image data provided by the MODIS sensor on the Terra satellite. Additionally, we utilized the Evaporative Demand Drought Index (EDDI) provided by the North Oceanic and Atmospheric Administration (NOAA) as a supplementary index to ESI, enabling us to perform more effective drought monitoring. We compared the degree and extent of drought in the southern region through four drought indices, and analyzed the causes and effects of drought from various perspectives. Findings indicate that the ESI is more sensitive in detecting the timing and scope of drought, aligning closely with observed drought trends.

  • The adaptation of smartfarm technology that converges ICT is increasing productivity and competitiveness in the agriculture. Technologies have been developed that enable environmental monitoring through various sensors and automatic control of the cultivation environment, and researches are underway to advance smartfarm technology using data generated from smartfarms. In this paper, an environmental control method to reduce the energy consumption of a smartfarm by using the environment and control data of the smartfarm is proposed. It was confirmed that energy consumption could be reduced compared to an independent environmental control method by creating an environmental prediction model using accumulated environmental data and selecting a control method to minimize energy consumption in a given situation by considering multiple environmental factors. In the future, research is needed to obtain higher energy efficiency through the advancement of the predictive model and the improvement of the complex control algorithms.

  • It is important to know know deleterious impact of deicing salt on plants for guidelines of planting along roads. The aim of this study was to determine the effect of calcium chloride ($CaCl_2$) on the growth and physiological characteristics of Liriope platyphylla and Pachysandra terminalis. The plants were grown from November of 2015 to March of 2016 in pots containing growing media with $CaCl_2$ at 0% (Control), 0.5%, 1.0%, 3.0%, and 5.0% (based on the weight). While plant growth and photosynthetic activity were significantly decreased in both plant species grown on the media with $CaCl_2$, the degree of sensitivity to $CaCl_2$ differed. The plant growth of Liriope platyphylla was considerably injured under higher than 3.0% of $CaCl_2$, whereas Pachysandra terminalis was all dead under higher than 1.0% of $CaCl_2$. This results indicate that Liriope platyphylla has higher degree of tolerance to the deicing salt than Pachysandra terminalis.

  • Objectives: We investigated the impacts of indoor plants on indoor air quality and occupational health, focusing on allergic rhinconjunctivitis and stress among employees in new office buildings. Methods: A total of 34 employees working at new public office buildings were enrolled as subjects (n=17, with indoor plants) and as a control (n=17) group. Before and after introducing indoor plants for three months, indoor air quality measurements including VOCs and aldehydes and questionnaires on sick building syndrome, AR symptoms (ARIA based), stress (DASS 42, KOSS, and SACL), and indoor characteristics were performed and statistically analysed. Results: Among the 34 enrolled subjects, 19 were included in the probable AR subject group (subjects with indoor plants, n=8, control n=11) and completed all questionnaires. Statistical analyses were done for total, AR subject groups, and controls. As a result, it was confirmed that major indoor air pollutants decreased after the introduction of indoor plants (p<0.5). Among major symptoms of allergic rhinoconjunctivitis, watery rhinorrhea, nasal stuffiness, and nasal itching indexes decreased (p<0.5, respectively). A decrease was noted in some areas of work-related stress indexes (mainly KOSS) among the subject group (total and AR) and a decrease of indoor environmental attractiveness among the control group (total and AR) (p<0.5, for all). Conclusions: Indoor plants may help reduce indoor air pollutants and decrease AR symptoms and work-related stress of employees in newly built office buildings. Various further follow-up studies on the mechanism of environmental, physical, and emotional influences and utilization of indoor plants in association with allergic diseases will be needed.

  • This study was conducted to investigate the effect of fine bubble water treatment on the growth of ginseng seedlings. The growth of ginseng seedlings which were treated with general water and fine bubble water was investigated. The above ground part, the growth of leaf was increased by about 10% and the growth of the stem was about 6%, as the ginseng seedlings which were treated with fine bubble water comparing to the ginseng seedlings treated with general water. Root length was increased about 5%, root width was increased about 8%, roots weight was increased about 9%, and dry weight was increased about 7%. This is not because the whole root growth was increased, but the main root growth was increased about 7%. These results suggested that the physical properties of the fine bubble water stimulated the growth of ginseng seedlings. These results are initial study in the case of ginseng seedlings. Therefore, it can be applicable to the 3-5 years old ginseng plants. Further research will be needed to find out the optimal cultivation condition by controlling the dissolved oxygen amount according to the soil condition and the research applied to the ginseng seedlings.
