We review novel chemical kinetics proposed for quantitative description of fluctuations in reaction times and in the number of product molecules in a heterogeneous biological system, and discuss quantitative interpretation of randomness parameter data in enzymatic turnover times of β-galactosidase. We discuss generalization of renewal theory for description of chemical fluctuation in product level in a multistep biopolymer reaction occurring in a dynamically heterogeneous environment. New stochastic simulation results are presented for the chemical fluctuation of a dynamically heterogeneous reaction system, which clearly show the effects of the initial state distribution on the chemical fluctuation. Our stochastic simulation results are found to be in good agreement with predictions of the analytic results obtained from the generalized master equation.

Electric vehicles (EVs) are considered a great alternative for reducing carbon emissions, and South Korea is striving to increase the penetration rate of EVs through supportive policies. However, the number of EV chargers is insufficient compared to the increasing penetration rate of EVs. Given the high cost and the requirement for high voltage, selecting an accurate installation location is crucial. Therefore, we propose a machine learning-based approach to predict the appropriate location for EV chargers using data that influences the selection of charger locations on Jeju Island. Additionally, we present a method for adjusting various machine learning conditions to enable precise selection of EV charger locations with high prediction accuracy.

전 세계적으로 기후변화에 대응하기 위해 탄소중립 달성을 위한 전략 중 하나인 생태계와 생태자원을 활용하여 탄소를 저감하는 자연기반해법 방안에 관한 연구들이 진행되고 있다. 본 연구에서는 생태계서비스 기반의 평가 모델인 InVEST Carbon, Coastal Blue Carbon 모델을 이용하여 부산 연안 육역과 연안 해역을 대상으로 탄소저장량 추정 및 경제적 가치 평가를 진행하였다. 연구 결과 부산 연안 육역은 부산 전체 육역과 비교하여 단위면적당 탄소저장량이 적으며, 현재 추진 중이거나 계획된 개발이 완료되면 탄소저장량은 더 감소할 것으로 나타났다. 연안 해역은 육역과 비교해 탄소저장량이 적은 것으로 나타났지만, 향후 생태자원을 활용하는 자연기반해법의 잠재성은 크다. 하지만 공유수면 매립과 같은개발 행위로 탄소저장량이 많은 중요 서식지에 영향을 줄 경우, 탄소저장량의 감소를 초래하며 이러한 부정적인 영향이 장기적으로 지속될 수 있는 것으로 나타났다. 따라서 부산 연안역의 지속가능한 관리를 위하여 탄소저장량을 고려한 생태계서비스 기반의 관리 전략이 필요하다.

In order to determine the most suitable computer interfaces for patients with high cervical cord injury, we report three cases of applications of special input devices. The first was a 49-year-old patient with neurological level of injury (NLI) C4, American Spinal Injury Association Impairment Scale (ASIA)-A. He could move the cursor by using a webcam-based Camera Mouse. Moreover, clicking the mouse could only be performed by pronation of the forearm on the modified Micro Light Switch. The second case was a 41-year-old patient with NLI C3, ASIA-A. The SmartNav 4AT which responds according to head movements could provide stable performance in clicking and dragging. The third was a 13-year-old patient with NLI C1, ASIA-B. The IntegraMouse enabling clicking and dragging with fine movements of the lips. Selecting the appropriate interface device for patients with high cervical cord injury could be considered an important part of rehabilitation. We expect the standard proposed in this study will be helpful.
