The present study was conducted to determine the community structure in Whang river based on the benthic macroinvertebrates. The survey area included eight sites in Whang river and two sites in Nakdong river and the study was carried out from March of 1995 to February of 1996. The result are as follows; (1) Benthic mactoinvertebrates are composed of a total of 200 species including 114 genera, 71 families, 21 orders, 7 classes in five phyla. A total of 200 species was found in Whang river, however only 66 species were recorded in Nakdong river. 2) Species frequency was different depending on the study area. It ranged from 84-112 species in the upper stream(site 1 to 6) to 71-75 species in the lower stream(site 7 to 8) and 41-58 species in the Nakdong river(site 9 to 10). Taxa with highest species frequency were aquatic insecta. 3) Average number of individuals was 1656.5/0.5㎡ in the whole study aera. Inividual number was variable from 53/0.5㎡ at the site 8 to 296.8/0.5㎡ at the site 4. Taxa with highest individual species frequency were aquatic insecta. 4) Trichoptera and Ephemeroptera were dominant in upper stream, while Chironomidae was the most aboundant group in the lower stream. 5) Average dominance(DI), species richness(RI), species diversity(H'), and evenness(J') were 0.68, 2.71, 3.10 and 0.71, respectively, in the whole study area. The biotic indices in Whang river were relative higher than that of Nakdong river. 6) Functional feeding groups were collectors and shredder at site 1 to 6, filterer at site 7 to 10.

Adverse transfusion reactions (ATRs) are unexpected reactions to transfusion. This study examined the frequency, types of ATRs, and related blood products retrospectively in pediatric patients with less information than in adult patients. Four hundred and forty transfusions were performed for two months at a children’s hospital: 247 units of red blood cell (RBC) products, 142 units of platelet products, and 41 units of fresh frozen plasma (FFP) were used. Five adverse reactions occurred in five patients, three cases were allergic reactions, and two were febrile nonhemolytic reactions. The frequency was 1.13%, and apheresis platelets and leukocyte-reduced RBC were transfused. Two patients’ ATRs were found in the previous transfusions, and ATRs were repeated in subsequent transfusions in one patient. One of the ATRs was not reported to the blood bank and was then discovered during the study. Because pediatric patients may have limitations in recognizing or expressing their symptoms compared to adults, medical staff rely solely on vital signs and laboratory results rather than symptoms, causing difficulty in noticing ATRs. Information on ATRs and education on appropriate blood products will improve awareness of ATRs and blood management among medical staff at transfusion sites and blood banks.

The present study was conducted to determine the water quality in Whang river based on the biological parameters, emphasized on the benthic macroinvertbrates. The survey area induced eight sites in Whang river and two sites in Nakding river and the study was carried out from March of 1995 to February of 1996. The result are as follows; (1) Benthic macroinvertebrates are composed of 200 species including 114 genrea, 71 families, 21 orders, 7 classes in five phyla. A total of 200 species was found in Whang river. In contrast, only 66 species were recorded in Nakdong river. (2) Trichoptera and Ephemeroptera wase dominant in the upper stream, while Chironomidae was the most aboundant group in the lower stream. (3) The diversity indices ranged from 2.654 to 3.608 depending on the site. The indices in Whang river were relative higher than that of Nakdong river. (4) In summary, all bilogical factors indicate that the water quality range from the level of two to the level of four. The water quality level was two or three in Whang river depending on the site and level was four in Nakdong river.

본 연구에서는 도로 위험 탐지를 위한 데이터 편향성 최적화 기반 연관 추론 모델을 제안한다. 이는 사용자의 개인적 특성과 주변 환경 데이터를 수집하고 교통사고 방지 서비스를 제공하기 위한 연관분석 기반의 마이닝 모델이다. 이는 다양한 상황 변수들로 구성된 트랜잭션 데이터를 생성한다. 생성된 정보를 바탕으로 연관 패턴 분석을 통해 각 트랜잭션 내 변수들의 유의미한 연관관계를 도출한다. 분류된 범주형 데이터의 편향성을 고려하여 최적화된 지지도 및 신뢰도 값으로 가지치기를 진행한다. 추출된 상위 연관규칙을 바탕으로 사용자에게 개인 특성과 주행 도로 상황에 대한 위험 탐지모델을 제공한다. 이는 데이터 편향성 문제를 극복하고 데이터간 연관성을 고려하여 잠재적인 도로 사고를 예방하는 교통 서비스가 가능하다. 성능 평가는 제안하는 방법이 정확도에서 0.778, Kappa 계수에서 0.743로 우수하게 평가된다. In this study, we propose an association inference model based on data bias optimization for road hazard detection. This is a mining model based on association analysis to collect user's personal characteristics and surrounding environment data and provide traffic accident prevention services. This creates transaction data composed of various context variables. Based on the generated information, a meaningful correlation of variables in each transaction is derived through correlation pattern analysis. Considering the bias of classified categorical data, pruning is performed with optimized support and reliability values. Based on the extracted high-level association rules, a risk detection model for personal characteristics and driving road conditions is provided to users. This enables traffic services that overcome the data bias problem and prevent potential road accidents by considering the association between data. In the performance evaluation, the proposed method is excellently evaluated as 0.778 in accuracy and 0.743 in the Kappa coefficient.

자녀와 부모간의 소통 부재 문제는 시간이 흘러갈수록 쉽게 해결되지 않는다. 또한 주거상의 물리적 차이로 인해 자녀는 부모의 위험 상황을 인지하기 힘들다 본 논문에서는 실내에서 발생할 수 있는 부모의 위험 상황 탐지와 스냅톡을 이용한 소통 증진 장려 애플리케이션을 제안한다. 이는 Hard-example mining과 Augmentation 정책 최적화를 사용한 딥러닝 기반의 학습 모델을 통해 위험 상황을 효과적으로 탐지한다. Firebased Cloud Messagingd을 이용하여 탐지된 위험 상황을 알리고 채팅 기능을 제공하는 애플리케이션 API 서버를 구축한다. 자녀는 간단한 사진 전송과 코멘트 기능을 제공하는 스냅톡 서비스를 통해 부모의 안전을 간단히 확인하고 소통을 위한 환경을 제공받는다. The problem of lack of communication between grown up child and parents is not easily solved over time. In addition, physical differences in housing make it difficult for grown up child to recognize the risk situation of their parents. In this paper, we propose an application that encourages communication enhancement using SnapTalk and detection of parental risk situations that can occur indoors. This effectively detects risk situations through deep learning-based learning models using hard-example mining and Augmentation policy optimization. We build application API server that informs detected risk situations and provides chat functionality using Firebase Cloud Messaging system. Grown up child is provided with an environment for simple verification and communication of their parents" safety through SnapTalk service, which provides simple photo transmission and commenting functions.
