In the Republic of Korea, public health centers conduct vector mosquito control in accordance with infectious disease prevention laws. However, most public health centers have traditionally conducted periodic, uniform vector control across their respective regions without considering specific information on vector occurrence. In 2021, The Korea Diseases Control and Prevention Agency(KDCA) launched a control project to shift the paradigm toward mosquito control strategy based on mosquito surveillance data. In 2024, 18 local public health centers will participate in this project, which will progressively expanding so that it can be used countrywide. Local public health centers evaluate mosquito monitoring data using data gathered from Daily Mosquito Monitoring System(DMS), which enables them to pinpoint the best times and locations for vector control. Vector control activities carried out by local public health centers are computerized utilizing Vector Control Geographic Information System(VCGIS). Using the new control strategy with mosquito surveillance, the number of mosquito occurrences, number of control activities, and amount of insecticides have decreased compared to the periodic control activities. Based on mosquito surveillance data, it is anticipated that evidence-based mosquito vector control will offer a more efficient and effective means of mosquito control.

Humanities is originally a comprehensive discipline, and all disciplines must be formed under the foundation of humanities. To do so, humanities researchers should break their own castles, return to their original positions based on the humanistic reflection, and try various academic methods. Humanities should no longer be the recipient of the data and the user's role alone. But rather they are expected to play the role of the data curator, the leading role in data production and construction and use of a common platform, and the attempt to use the platform in various ways by the constant re-datafication make all relevant researchers enable collaboration. In addition, it is necessary to have the ability to solve problems through multi-fields, trans-fields, or cross-fields, which can be achieved not only by building basic knowledge in all fields of studies, but also by sharing interest, active participations, and diverse collaborations. We need to have critical and rational perspectives, and inclusive attitudes based on acceptance of differences, and all of these can be supported by our endeavors to solve structural problems.

This study suggested a new real-time traffic signal operation algorithm using combined data of travel time and occupancy rate. This study applied the travel time data to traffic signal control system, and developed the signal operation algorithm based on saturation degree that was calculated using the travel time data. This algorithm calculates a queue length using a delay model, and converts the queue length to the saturation degree. Moreover, it calculates signal timing variables using this combined saturation degree. This study conducted a microscopic simulation for effectiveness evaluation. We checked that the average intersection delay decreased by up to 27 percent. Moreover, we checked that this signal operation algorithm could respond to a traffic condition of oversaturation and loop detector error effectively and usefully. In korea, sectional traffic detection systems are being installed in various ITS projects, such as Advanced Transportation Management System(ATMS) and Urban Transportation Information System(UTIS). This study has important significance in the sense that it is new methodology to accept the sectional detection system in traffic signal control system.

Real-life time series characteristic data has significant amount of non-stationary components, especially periodic components in nature. Extracting such components has required many ad-hoc techniques with external parameters set by users in a case-by-case manner. In this study, we used Empirical Mode Decomposition Method from Hilbert-Huang Transform to extract them in a systematic manner with least number of ad-hoc parameters set by users. After the periodic components are removed, the remaining time-series data can be analyzed with traditional methods such as ARIMA model. Then we suggest a different way of setting control chart limits for characteristic data with periodic components in addition to ARIMA components.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16, 574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

Monitoring autocorrelated processes is prevalent in recent manufacturing environments. As a proactive control for manufacturing processes is emphasized especially in the semiconductor industry, it is natural to monitor real-time status of equipment throug

The study investigates the various Acceptance Control Charts (ACCs) based on the factors that include process independence, data weighting scheme, subgrouping, and use of control charts. USL - LSL 〉 6Σ that used in the good condition processes in the ACCs are designed by considering user's perspective, producer's perspective and both perspectives. ACCs developed from the research is efficiently applied by using the simple control limit unified with APL (Acceptable Process Level), RLP (Rejectable Process Level), Type I Error α, and Type II Error β. Sampling interval of subgroup examines i.i.d. (Identically and Independent Distributed) or auto-correlated processes. Three types of weight schemes according to the reliability of data include Shewhart, Moving Average(MA) and Exponentially Weighted Moving Average (EWMA) which are considered when designing ACCs. Two types of control charts by the purpose of improvement are also presented. Overall, α, β and APL for nonconforming proportion and RPL of claim proportion can be designed by practioners who emphasize productivity and claim defense cost.

Models are useful tools for understanding and improving biological control of arthropod pests by means of natural enemies. Thus, models can be applied to simulate various scenarios in order to identify optimal control strategies. Although simulations can never replace real experiments, they can often serve as guidelines for choosing relevant field experiments and thereby save a lot of laborious and costly field work. Whereas the processes underlying population dynamics (e.g. dispersal, functional response, mutual interference) can be studied under laboratory conditions, large-scaled experiments in the field or in greenhouses are unsuited for this purpose. Instead such experiments may provide information about the patterns (e.g. spatial distributions of prey and predators) generated by the underlying processes. A major purpose of modeling is to link the patterns to the processes that generate these patterns. Petri-dish and single plant experiments have clearly demonstrated the capacity of predacious mite Phytoseiulus persimilis to feed effectively on the two-spotted spider mite Tetranychus urticae. This quickly leads to reductions in the abundance of prey, followed by a decline in predator abundance and eventual extinction. However, when larger systems, consisting of many hundred plants, are infested with the two mite species, extinction of one or both species seems less likely at the system level, although it may still occur at the individual plant level. The qualitative difference between small and large systems with respect to persistence and extinction risks is attributed to the fact that mites move among plants, but to prove that dispersal per se plays a role for the overall dynamics is hard to demonstrate experimentally. To circumvent this problem, I developed a stochastic simulation model of a greenhouse system that explicitly incorporates within and between plant dynamics. The model is used for analyzing a series of experiments with biological control of spider mites in multi-plant systems. In these experiments, the number of plants as well as their connectivity and the numbers of introduced mites were varied in order to examine whether these factors affect e.g. the predator-prey ratio or the time to extinction of one or both species. In my presentation I will also demonstrate an interactive version of the model (called DynaMite). It allows the user to interfere in the system during a simulation so as to mimic the options a grower has in order to prevent losses and to maximize his profit. Such options include spraying with acaricides, releasing predators, and replanting in substitute of damaged plants. By choosing different control strategies, the user may gradually improve his skills according to the principle of learning by experience.

In this paper we present a newly improved telescope control software and a newly developed data analysis software package for effective use of the Solar Flare Telescope(SOFT) The telescope control software permits us to make not only auto tacking of the SOFT, but also quantitative measurement of the solar irradiation, allowing us to provide weather monitorings. In addition we introduce an IDL widget software package for both monochromatioc (MONO version) and polarimetric data (VMG version) analysis. The MONO version is capable of loading FITS files, changing colors and contrast, image processing, displaying plots, and saving displayed plots by selected formats The VMG version, on the other hand provides a calibration of polarimetric data and plots of reduced vector magnetic fields.

Regional air quality regulation is a system that allows the Minister of Environment to designate the local area as air quality control region where the concentrations of air pollutants are exceeding the environmental standards, and the local governments that administrate the regulated area have to develop and practise a plan for reducing the air pollutants. From the data observed yearly by the monitoring stations in 8 provincial cities with more than 0.5 million people was judged the compliance with air quality standards in each municipality for the period of 2003 to 2013. As the result of investigation on air pollutants concentrations of each city, it was found that there was no station that exceeds the ambient air quality standards of CO, SO2 and 24-hour NO2. But all municipalities exceeded the standards of 8-hour O3, annual and 24-hour PM10, and therefore 8 municipalities can be designated to be under the local air regulation. For the annual NO2 were the monitoring sites necessary requirements for designation of the air quality regulation region in Cheongju, Cheonan, Daejeon and Gwangju area. Incase of 1-hour O3, some of stations in Pohang, Cheongju, Cheonan and Changwon area were over the designation standards for the air quality control region.

고해상도의 정량적 실황강우장을 산정하기 위해서는 양질의 고밀도 강우관측망 정보가 필요하다. 이를 위해 본 연구에서 정량적 실황강우장 산정을 위한 입력자료로 SK 플래닛의 고밀도 복합기상센서 관측망과 기존 기상청 관측망을 이용하고자 하였다. 이를 위해 서울지역에 위치한 SK 플래닛의 복합기상센서 관측망을 소개하고, 2013년 7～9월 3개월 동안의 관측자료의 품질을 분석하였다. 품질분석 결과, SK 플래닛 관측소가 일부 관측소를 제외하고 대부분 기존 관측망과 유사하게 강우를 관측하는 것을 확인할 수 있었다. 다만, 일시적인 기계 및 자료 전송 오류로 인해 발생할 수 있는 결측치 및 이상치가 미치는 영향을 최대한 저감하기 위해서 오자료를 실시간으로 보정할 수 있는 품질보정 기법을 개발하였으며, 개발된 기법이 적절히 강우를 보정하는 것을 확인하였다. 이를 통해 결측률이 20% 미만이면서 오자료의 영향이 최소가 되는 190개소(기상청 34개소, SK 플래닛 156 개소)를 정량적 실황강우장 산정에 활용하였다. 또한, 약 3 km2의 밀도를 갖는 고해상도 관측망을 이용하여 산정된 강우분포장의 재현성을 기존 기상청 관측망의 결과비교를 통해 평가한 결과, 고밀도 관측망을 통해 산정된 강우분포장의 빈도곡선이 레이더 공간분포장과 유사하며, 기존 기상청 관측망의 공백을 보완할 수 있음을 확인하였다. 특히, 이 결과를 통해 고밀도의 강우관측 결과를 활용한다면 레이더 참강우장에 근사한 공간분포된 강우를 산정할 수 있다는 것을 확인할 수 있었다.

현재 공용중인 대부분의 시설물들은 다양한 센서로 구성된 계측시스템을 구축하고 있으며, 시스템에서 계측된 응답 데이터 분석을 통해구조물의 건전성을 평가하고 있다. 건전성 평가 과정에서 적용하는 계측데이터의 계측관리기준은 일반적으로 공용 초기에 설정된 것으로,시공회사 또는 설계회사 소속의 전문가들이 설계기준을 바탕으로 혹은 구조해석을 통해 설정하고 있다. 하지만 실 계측데이터에 적용하기위해서는 이와 같이 설정되는 계측관리기준의 검증이 필요하며, 일부 연구자들은 교량의 관리를 위해 실 계측데이터에 계측관리기준을 적용하여 타당성을 검증하는 연구를 수행하고 있다. 본 논문에서는 통계적 접근방법을 활용하여 기설정된 계측관리기준을 검토하고, 체계적인 계측관리기준 재설정 방안을 제시하였다. 또한 구조물의 실 계측 데이터에 적용하여 그 타당성을 검증하였다.

Quality control of Argo(Array for Real-time Geostrophic Oceanography) data is crucial by reason that salinity measurements are liable to experience some drift and offset due to biofouling, contamination of sensor and wash-out of biocide. The automated Argo real-time quality control has a limit of sorting data quality, so that WJO program is adopted as standardized method of Argo delayed mode quality control (DMQC) in the world that is a precise quality control method. We conducted DMQC on pressure, temperature and salinity measured by Argo floats in the Pacific Ocean including expert evaluation. Particularly, salinity data were corrected using WJO program. 4 salinity profiles of Argo delayed mode were compared with nearby in situ CTD data and other Argo data in deep layer where oceanographic conditions are stable in time and space. The differences of both salinities were lower than target accuracy of Argo. As compared with the difference of salinities before DMQC, those after DMQC decreased by 60-80 percent. Quality of delayed mode salinity data seemed to be improved correcting salinity data suggested by WJO program.
