In this paper, we propose a integrated real-time monitoring system for recycling agriculture resourcing based on USN. We design and implement the monitoring system so that we can integrate the quality control of farmyard and liquid manures, barn environment monitoring, and positioning information control into a total management system performing recycling of excrement and manure. Selection of sensors and sensor-node construction and requirements, structure of wire/wireless communication networks, and design of monitoring program are also presented. As a result of operating our system, we can get over various drawbacks of conventional separated system and promote the proper circulation of excrement up to the farmyard. We confirm that these advanced effects arise from the effective management of the total system integrating quality control of farmyard/liquid manure, barn/farmhouse information, and vehicle moving monitoring information etc. Moreover, this monitoring system is able to exchange real-time information throughout communication networks so that we can construct a convenient information environment for agricultural community by converging IT technology with farm and stockbreeding industries. Finally we present some results of processing using our monitoring system. Sensing data and their graphs are processed in real-time, positioning information on the v-world map offers various moving paths of vehicles, and statistical analysis shows all the procedure from excrement occurrence to recycling and resourcing.

This paper focuses on the applicability of a continuous monitoring method on trace sulfur compounds in the ambient air by TD and GC/PFPD. The target compounds for monitoring include H2S(hydrogen sulfide), Methyl mercaptan, Dimethyl Sulfide, and Dimethyl disulfide. The result of QA/QC on monitoring instruments satisfies all the standards of Odor Measurement and Analysis Method, showing that the reproductivity of the compounds by concentration is within 10%, linearity is above 0.98 of a correlation efficient, method detection limit is 0.16 ppb by MM standard, and recovery rate is over 70%. Monitoring was conducted for two years from March 2006 to February 2008. As a result of the monitoring, the average concentration of H2S was 0.08 ppb, with the maximum concentration at 16.15 ppb. The result indicates that it is reasonable to do continuous monitoring as there appears a spontaneous event of high concentration by the condition of the site during monitoring odor-causing substances. Therefore, it is suggested that the continuous monitoring method used in this paper is appropriate to identify the characteristics of sudden occurrence and concentration variations of sulfur compounds.

The purpose of this study is to examine to control of glucose level and the occurrence of chronic complications of diabetes by compliance groups with health care regimen The subjects were consisted of 300 out patients with type 2 diabetes mellitus from beginning of March through the end of April in 2001, who visited at the endocrinology department at Kangnam St. Mary's Hospital of Catholic University in Seoul. The patient's compliance level with health care regimen was assessed at questionnaire. However, the blood glucose level and the occurrence of chronic complications of diabetes were assessed at medical record review. The data were analyzed by SAS program for chi square test and t-test. The results were as follows. 1. Significant differences were found among the factors such as duration of diabetes, the number of participation of diabetes educational program, job, smoking, self monitoring of blood glucose and the methods of diabetes therapy between high and low compliance groups. High compliance group patients had a diabetes longer than low compliance group patients. High compliance group patients more frequently attended the educational program and checked themselves monitoring blood glucose than low compliance group patients. Also, they did not work recently, smoked less and got more insulin injection therapy compared to low compliance group patients. 2. No significant differences were found among the result of fasting blood glucose. 2-hour postprandial blood glucose, and $HbA_{l}c}$ between high and low compliance groups. 3. The occurrence rate of macrovascular complications of chronic complications of diabetes were lower, however, the occurrence rate of microvascular complications were higher in high compliance group than in low compliance group with health care regimen.

국내 지하수의 비소 산출양상을 평가하기 위하여 환경부 지하수 수질측정망 자료를 활용하였다. 2001년-2006년의 기간동안 전체 측정망의 약 3.0%에서 $5.0{\sim}188{\mu}g/L$ 범위로 비소가 검출되었으며 지리적으로 산출빈도가 높은 3개의 그룹으로 구분되어졌다: 인위적 기원으로 예상되는 서울 및 수도권지역, 지질기원으로 파악되는 충북지역 및 경남지역 자연적 비소산출은 옥천대 변성퇴적암과 백악기 화산암 지질분포 지역과 잘 일치하여 나타나며 이들 지역의 기존 연구자료를 평가한 결과, 광상구 및 열수변질 지역에서 주로 황화물의 산화반응에 의한 비소유출이 발생한다. 또한 옥천대 변성퇴적암 지역의 상대적으로 단순한 수질유형과 다소 높은 pH조건에서는 탈착반응도 기여하는 것으로 추정된다.

남해 중부해역에서 적조발생과 관련해서 기상인자와의 상관성을 요약하면 다음과 같다. 적조 다발원 비교에서 강수량이 적조 발생과 밀접한 상관을 보였다. 즉, 강수량은 육지 및 연안지역의 영양염류를 해역으로 유입시킴으로서 적조발생의 영양 공급원으로 중요한 역할을 한다. 이때의 기온은 대체로 적조 다발철인 여름과 초가을에 높은 값을 유지했다. 그러나 일조시수나 바람은 적조발생에 직접적인 연관성을 가지지는 않은 것으로 사료된다.

The amount of damage suffered from the red tide occurring at the near shore is increasing rapidly. The Windows visual system discussed in this paper is developed in order to help minimize the damage. The system is focused on the monitoring the coastal environment. and forecasting the red tide occurrence. Although several similar systems are now existing. most of them are based on the web application. which cause the large response time. limited presentation ability of data. and inability of data storing at client side. The Windows visual system described in this paper operates on the Internet to get the ubiquitous access. One of three components of the Windows visual system. client system is developed as a Windows application in order to overcome the weak points of the previous systems. The gathering. analysis, and monitoring of data can be done at real time using the Windows visual system.

Nowadays, base isolation systems such as lead-rubber bearing, elastomer bearing and sliding bearing have been installed to the various structures to prevent the disaster from seismic. The performance of base isolation system have been well proved by model-scale experiments and numerical analysis. However. the seismic response data measured at real large base-isolated structures is still insufficient. This paper presents a seismic monitoring system, acquiring real-time acceleration signals up to 32 channels, displaying time history and spectrum of the signals, storing the acquired data at a PC hard disk, and replaying the saved data. Moreover, the system can be operated without any limitation for monitoring period by automatic management of stored data file. The developed system has been installed at a real base-isolated building using lead-rubber bearings and we expect its seismic response data with ground motion signal can be well licquired in case of earthquake occurrence.

Groundwater monitoring wells (about 70 wells) were extensively installed in 28 sites surrounding Lake Texoma, located on the border of Oklahoma and Texas, to assess the impact of geochemical stressors to shallow groundwater quality. The monitoring wells were classified into three groups (residential area, agricultural area, and oil field area) depending on their land uses. During a two-year period from 1999 to 2001 the monitoring wells were sampled every three months on a seasonal basis. Water quality assay consisted of 25 parameters including field parameters, nutrients, major ions, and trace elements. Occurrence and level of inorganics in groundwater samples were related to the land-use and temporal change.

Red tide(harmful algae) in the Korean Coastal Waters has a given a great damage to the fishery every year. However, the aim of our study understands the influence of meteorological factors (air and water temperature, precipitation, sunshine, solar radiation, winds) relating to the mechanism of red tide occurrence and monitors red tide by satellite remote sensing, and analyzes the potential area for red tide occurrence by GIS. The meteorological factors have directly influenced on red tide formation. Thus, We want to predict and apply to red tide formation from statistical analyses on the relationships between red tide formation and meteorological factors. In future, it should be realized the near real time monitoring for red tide by the development of remote sensing technique and the construction of integrated model by the red tide information management system (the data base of red tide - meteorological informations). Finally our purpose is support to the prediction information for the possible red tide occurrence by coastal meteorological information and contribute to reduce the red tide disaster by the prediction technique for red tide.
