Abstract Over the last several decades, crop production in the United States increased largely due to the extensive use of animal waste and fertilizers as plant nutrient supplements, and pesticides for crops pests and weed control. Without the application of animal waste best management, the use of animal waste can result in nonpoint source pollution from agricultural land area. In order to increase nutrient levels and decrease contamination from agricultural lands, nonpoint source pollution is responsible for water quality degradation. Nonpoint source pollutants such as animal waste, ferilizers, and pesticides are transported primarily through runoff from agricultural areas. Nutrients, primarily nitrogen and phosphorus, can be a major water quality problem because they cause eutrophic algae growth. In 1985, it was presented that Watershed/Water Quality Monitoring for Evaluation BMP Effectiveness was implemented for Nomini Creek Watershed, located in Westmoreland County, Virginia. The watershed is predominantly agricultural and has an aerial extent of 1505 ha of land, with 43% under cropland, 54% under woodland, and 3% as homestead and roads. Rainfall data was collected at the watershed from raingages located at sites PNI through PN 7. Streams at stations QN I and QN2 were being measured with V-notch weirs. Water levels at the stream was measured using an FW-l Belfort (Friez FWl). The water quality monitoring system was designed to provide comprehensive assessment of the quality of storm runoff and baseflow as influenced by changes in landuse, agronomic, and cultural practices ill the watershed. As this study was concerned with the Nomini Creek Watershed, the separation of storm runoff and baseflow measured at QNI and QN2 was given by the master depletion curve method, and the loadings of baseflow and storm runoff for TN (Total Nitrogen) and TP (Total Phosphorus) were analyzed from 1987 through 1989. The results were studied for the best management practices to reduce contamination and loss of nutrients, (e.g., total nitrogen and total phosphorus) by nonpoint source pollution from agricultural lands.

Background : Review of readmissions in health care facilities is necessary from the viewpoint of both economic concerns and quality considerations. To identify the characteristics, factors, and causes of multiple admissions in comparison with single admissions is essential for both providers and payers in order to assure quality care and efficient use of medical resources. Methods: All discharges from an university hospital in 1993 were analyzed, and the characteristics of multiple admissions were identified and were compared with those of single admissions by using the data bases of the discharge abstract and billing for reimbursement. Medical records of patients readmitted within 6 days after the previous discharge were reviewed to identify the reasons for such prompt readmission. Statistical analysis between groups of patients were performed by using SPSS. Result : The mean age was higher in multiple admissions than those of single admissions, and the average length of stay was longer in multiple admissions than in single admissions. The hospital cost per day is higher in single admissions while the cost per case is higher in multiple admissions. More than half of readmissions occurred within one month after the preceding discharges. Above 15% of the readmission within 6 days after the preceding discharges seemed to have close relationship with quality of care provided during the preceding hospitalization. The death rate of the patients readmitted within 6 days was the highest in comparison with multiple admissions and single admissions. Conclusion : Potential preventable readmissions should be reduced by identifying characteristics of multiple admissions, especially unplanned readmission, and by applying some interventions such as standard predischarge assessment or careful follow-up care after discharge for high risk readmission groups. As the results of these efforts, health care facilities could achieve quality improvement in medical care, and effective use of hospital resources.

센서 네트워크 미들웨어는 센서 하드웨어와의 연관을 최소화하고, 어플리케이션 개발을 용이하게 하며, 추상적인 데이터 접근 방법을 제공 하기 위한 연구들로 많은 연구자들에게 관심을 받고 있다. 그러나 기존의 미들웨어는 실행코드를 해석하기 위한 해석기가 모든 노드에 설치되어야 하며, 이는 추가적인 컴퓨팅 및 통신 오버헤드를 야기하였다. 이를 해결하기 위하여 본 논문에서는 게이트웨이에서 센서 오버레이 네트워크를 이용하여 운용되는 TinyONet-Lite를 제안하였다. TinyONet-Lite에서 가상 센서는 물리적 센서의 가상 대응체로 동작하고, 동적으로 연합하여 오버레이 네트워크인 슬라이스(Slice)를 만들어 미들웨어 서비스를 제공한다. 플랫폼의 효율을 보여주기 위해서 이 논문은 TinyOS를 가진 하드웨어 모트(mote)위에 TinyONet-Lite를 구현했고, 여러 실험을 수행하였다. 실험에 의하면, 기존의 연구와 비교했을 때 TinyONet-Lite는 확장성, 동적서비스 구성이 우수하며, 오버헤드를 줄일 수 있었다.

MANET(Mobile Ad-Hoc Network) 환경의 센서 네트워크는 고정된 기반 없이 센서 노드간의 자율적이고 독립적인 네트워크를 구성한다. 또한, 네트워크를 구성하는 센서 노드의 이동으로 인한 토폴로지의 변화로 인해 데이터 처리, 제어 등을 효율적으로 관리하는데 많은 어려움이 있다. 특히, 각 센서 노드는 반드시 이동성을 고려해야 하기 때문에 에너지 사용에 대한 문제점이 발생한다. 이러한 문제를 해결하기 위해 클러스터 헤더와 멤버간 계층적 구조의 클러스터를 구성하는 기법들이 제안되었다. 하지만, 센서 노드의 센싱 파워 레벨이 일정하여 비효율적인 에너지 소비를 수반해 센서 네트워크의 에너지 불균형 및 생존 시간의 단축을 가져온다. 본 논문에서는 기존의 클러스터링 기법이 갖는 이러한 문제를 해결하기 위해 효율적 에너지 관리를 위한 지능형 클러스터링 기법을 제안하였다. 제안한 기법은 센서 노드의 이동에 따른 네트워크 토폴로지 변화에 빠르게 대응하고, 연속된 센싱을 요구하는 상황에서 기존의 기법에 비교하여 센서 노드의 생존 시간 향상을 가져온다.

Objectives: We performed a systematic review to assess and aggregate the available evidence on the frequency, expected effects, obstacles, and facilitators of disclosure of patient safety incidents (DPSI). Methods: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for this systematic review and searched PubMed, Scopus, and the Cochrane Library for English articles published between 1990 and 2014. Two authors independently conducted the title screening and abstract review. Ninety-nine articles were selected for full-text reviews. One author extracted the data and another verified them. Results: There was considerable variation in the reported frequency of DPSI among medical professionals. The main expected effects of DPSI were decreased intention of the general public to file medical lawsuits and punish medical professionals, increased credibility of medical professionals, increased intention of patients to revisit and recommend physicians or hospitals, higher ratings of quality of care, and alleviation of feelings of guilt among medical professionals. The obstacles to DPSI were fear of medical lawsuits and punishment, fear of a damaged professional reputation among colleagues and patients, diminished patient trust, the complexity of the situation, and the absence of a patient safety culture. However, the factors facilitating DPSI included the creation of a safe environment for reporting patient safety incidents, as well as guidelines and education for DPSI. Conclusions: The reported frequency of the experience of the general public with DPSI was somewhat lower than the reported frequency of DPSI among medical professionals. Although we identified various expected effects of DPSI, more empirical evidence from real cases is required.

Purpose: The purpose of this study was to analyze the changes of the relative impulse of the foot when carrying 5 types of schoolbag during level walking. Methods: Forty-four normal subjects were divided into 5 groups according to the method of carrying a bag: carrying no bag (condition 1), a backpack (condition 2), a shoulder bag (condition 3), a cross bag (condition 4) and a one-hand bag (condition 5). To evaluate the partial relative impulse, 7 areas were measured on the sole of a foot: the hallux, toe, 1st metatarsal head (Met1) and the 2nd & 3rd metatarsal heads (Met2/3), the 4th & 5th metatarsal heads (Met4/5), mid foot and heel. Repeated one-way analysis of variance (ANOVA) and independent t-tests were used to analyze the statistical data. Results: In the right foot, the relative impulses in every areas revealed no significant difference (p>0.05), however, the relative impulses at Met1, Met2/3, Met4/5 and heel were significantly different between the different conditions (p<0.05). There were significant differences on comparing the relative impulse between left and right foot within one condition, the mid foot in condition 2, as well as the hallux and Met1 in condition 3 (p<0.05). In condition 4, the toe, Met1, Met4/5 and mid foot were significantly different (p<0.05). The values at the hallux, toe and Met1 in condition 5 also were significantly different (p<0.05). Conclusion: These findings showed that the symmetrical relative impulse of the foot was present in the case of carrying a backpack, but there was an extra load on specific regions and asymmetrical relative impulses in the case of carrying a shoulder bag, a across bag and a one-hand bag.

Purpose: This study aimed to systematically analyze the reliability and validity of Korean versions of mobility and gait assessment tools for patients with stroke. Methods: Two reviewers conducted an independent literature search and systematically reviewed the literature. Literature published until June of 2017 was searched using search engines for electronic databases. The 2 reviewers reviewed the title and abstract of each article. Among the articles examined, we read the full text of those judged to be suitable for our study. We classified the selected data into research methods and results. The determination was made through mutual agreement. Results: The reviewers selected 5 articles related to the purpose of this study. The DGI was found to be moderately associated with BBS, 10MWT, and TUG in intra-rater reliability (ICC=0.92), inter-rater reliability (ICC=0.88), and concurrent validity tests. The FGA demonstrated a high level of reliability with intra-rater (ICC=0.92-0.95) and inter-rater reliability (ICC=0.91, 0.95). The intra-rater reliability of the RMI was high at ICC=0.98. Its concurrent validity showed a high association with STREAM and BI. The intra-rater reliability of the MAS was ICC=0.75-0.99. Its inter-rater reliability was very high, exceeding 0.99. The inter-rater reliability of the Tinetti-gait Scale was ICC=0.91, and its concurrent validity was moderately associated with the DGI, 10WMT, OLST, FM-L/E, and STS. Conclusion: The results of this study revealed that the reliability and validity of the Korean versions of the mobility and gait assessment tools were high.
