A Study on the Hopfield Neural Scheme for Data Association in Multi­Target Tracking

Lee, Yang­-Weon The Korea Institute of Information and Commucation 2003 한국정보통신학회논문지 Vol.7 No.8

In this paper, we have developed the MHDA scheme for data association. This scheme is important in providing a computationally feasible alternative to complete enumeration of JPDA which is intractable. We have proved that given an artificial measurement and track's configuration, MHDA scheme converges to a proper plot in a finite number of iterations. Also, a proper plot which is not the global solution can be corrected by re­initializing one or more times. In this light, even if the performance is enhanced by using the MHDA, we also note that the difficulty in tuning the parameters of the MHDA is critical aspect of this scheme. The difficulty cat however, be overcome by developing suitable automatic instruments that will iteratively verify convergence as the network parameters vary. 본 논문에서는 다중표적 추적을 위한 데이터 결합 기법 중에서 MHDA 스킴을 제안하였다. 이 구조는 기본의 JPDA보다 계산면에서 단축이 가능하여 실제 응용에 많은 적용이 기대된다. 인위적인 측정값과 표적을 이용하여 시뮬레이션을 수행한 결과 MHDA는 기존의 JPDA보다 성능도 비슷한 특성을 보이는 것을 확인하였다.

농업연구에서의 반복측정설계에 대한 일반화선형혼합모형의 응용

양경숙,한원석 高麗大學校 統計硏究所 1999 應用統計 Vol.14 No.-

농업연구에서 시행되는 시험들 중에는 여러 달에 걸쳐 반복 측정되거나 여러 해에 걸쳐 동일한 실험을 반복 관측하는 사례들이 많다. 그러나 대부분의 자료분석에 있어서 반복 관측된 자료의 구형성 가정을 고려하지 않고 분석하고 있다. 따라서 본 논문에서는 반복요인을 고려한 분산분석방법에 대한 이론적 고찰과 2가지 사례를 통해 반복 측정된 농업시험에 대한 일반화선형혼합모형의 적용을 제안한다. Lots of data in agricultural experiments of the Rural Development Administration of Korea have been obtained by repeated measures design. However, such data have been analyzed without considering the correlation of repeated measures data. In this research report, we propose to application of methods based on to mixed model with special parametric structure on the covariance matrices in addition to univariate and multivariate analysis of variance, especially, on repeated measures data in agricultural experiments.

이양원,나현식,이택희 호남대학교 정보통신연구소 1996 정보통신연구 Vol.5 No.-

본 논문은 본교에 광역 캠퍼스 네트웍 구축시 사용할 수 있는 캠퍼스 네트웍 구축방안에 대한 연구 결과이다. 먼저 학교 특성에 맞는 요구 사항의 도출 및 현재의 네트웍 장비개발 기술현황 분석을 수행하였다. 그리고 본교의 LAN 설계시 중요 고려요소로는 멀티미디어의 실시간 정보 교환 기능과 지역 8개 대학간 원격교육에 대비하여 다수채널의 동영상 부하의 감당 능력, 학, 내이의 데이터 베이스 검색이 가능하도록 설계하였다. 요구사항을 실현하기 위하여 본 논문에서는 실시간 지원이 강력하고 대역폭이 넓어 요구 조건을 만족하는 ATM 기반의 망구조를 제시하였다. In this paper. we designed and proposed the Honam university's campus network using ATM(Asynchronous Transfer Module). we showed the specific differences between ATM and existing networks in view of performance and protocols. We confirmed that ATM is proper for our campus network which is going to transfer the multimedia, image and sound data in the near future. We suggested two campus networks. The first one is using two ATM switches which will be located in Engineering Hall(Building?8) and Computer center(Building?5) respectively, since we assumed that the data traffic is mainly occurred between two buildings, But In this case, the cost is too high. We suggested modified network which can reduce the cost and guarantee the speed performance. In this design we omitted the second ATM switch which will be installed on the engineering building. We used optical cable for cabling between buildings. But we used class 5 UTP(untwisted pair) cables for intra cabling in the building. We assigned that each professor's office is two ports and each lecture room is one port. So, totally, it needs about 2.200 ports. We assured that if this kind of network is implemented in the near future. it is possible to connect both the government's network highway and Korea satellite. Above all. it is able to implement the remote education between 8 regional universities using satellite network. Also it will help to get high degree in university evaluation which will be scheduled on 1998.

연구 목적 : 본 연구의 목적은 입원치료후 퇴원한 품행장애 환자들의 예후와 가족들의 정신과 입원치료의 효능에 대한 인식도를 알아보고 예후에 영향을 미칠 수 있는 요인을 알아보기 위한 것이다. 방법 : 품행장애의 진단 하에 7일 이상 입원치료를 받았으며 퇴원 후 6개월이 경과된 300명 중 전화 추적이 가능하였던 96명에서 퇴원 후 문제행동, 가족관계, 가족들의 인식도를 조사하였으며 이와 관련된 요인을 알아보았다. 결과 : 퇴원 후 문제행동의 양상은 입원전보다 호전된 경우가 90%이었으며 더 심해진 경우는 2%이었으며 8%는 변화가 없었다. 퇴원 후 가족관계는 보다 좋아진 경우가 70%, 나빠진 경우가 2%, 별 차이가 없는 경우가 28%이었다. 병원치료의 효율성에 대한 가족들의 인식도는 도움이 되었다는 경우가 57%, 해가 되었다는 경우가 6%, 그저 그렇다가 37%이었다. 퇴원 후 문제행동, 가족관계, 가족들의 입원치료에 대한 인식도 등 세 가지 항목이 모두 양호하다고 답변한 대상을 양호군으로 설정하고 그 외의 대상을 대조군으로 하여 양군의 특성의 차이를 비교하였을 때 양호군의 연령이 유의하게 낮았으며 가족 형태의 문제가 있었고 MMPI하위척도 중 남성성 -여성성 척도 점수가 유의하게 높았다. 결론 : 비록 본 연구는 여러 제한점이 내포되어 있음에도 불구하고, 정신과 입원치료를 받았던 청소년의 행동이 대부분은 호전된다는 것을 시사하여 품행장애에서의 정신과적 치료에 상당히 고무적인 결과를 나타내었으며 추후 대상자와 치료프로그램의 다양성을 통제한 연구를 지속하는 것이 필요할 것으로 생각되었다. 중심 단어 : 품행장애ㆍ청소년ㆍ예후ㆍ입원치료. Objectives : The major goal of this study was to investigate the treatment outcome of psychiatric treatment in inpatients with conduct disorder and to elucidate factors affecting its prognosis. Methods : We reviewed the medical records of 300 inpatients with conduct disorder who had been treated with a specialized adolescent treatment program. Follow-up structured telephone interview had been performed in 96 patients. Results : 1) At the point of follow-up, 90% of the patients were improved in behavioral patterns, 2% of the patients were worse, and 8% of the patients were unchanged. 2) Intrafamilial relationship was improved in 70% of the patients, worse in 2%, and unchanged in 28%, 3) Fiftyseven percent of families thought to be helped by psychiatric inpatient treatment, 6% replied to be harmed, and 37% thought not to be helpful. 4) Comparing the good prognosis group who were all better in behavioral patterns, intrafamilial relationship, and efficacy of treatment with the rest of subjects, the good prognosis group was significantly younger and had more history of problems in familial structure. Conclusion : Although the present study had some meterological limits, the promising positive results in the outcome of inpatients with conduct disorder encourages further more sophisticated investigations in this problematic psychiatric conditions. KEY WORDS : Conduct disorderㆍAdolescentㆍTreatment outcomeㆍInpatient treatment.

The purpose of this paper is to examine the kinds of data and usage of time-series pattern databases and to identify common characteristics among the different disciplines. Most time- series pattern databases do not use general purpose database management systems. The main reason is that they have data structures and usage patterns that cannot be easily accommodated by existing database management systems. It is the purpose of this paper to identify the special database management needs of time-series pattern databases, and to point out directions for design of time-series pattern database systems. We discuss the requirements of time-series databases, and list the properties identified for them. Conclusions are drawn as to the preferable data management methods needed in support of time-series pattern databases.

시계열 패턴 응용을 위한 질의어 처리기 설계

이양원,김영인 群山大學校 1995 論文集 Vol.22 No.-

Although the time series pattern increasingly requires access of large quantities of data, cur-rent databases technology fails to meet the needs in a number of areas. To overcome problems among users, database systems must provide query language that includes traditional database operators as well as time series operators for the time series pattern. In this paper, we present an extended SQL for applications of the time series pattern. We have identified operators that should be implemented in the query language to support similarity and range based queries. The paper also demonstrates that numerous example using time series operators. Since a conventional DBMS does not support time series operations, we also propose the architecture of query processor. This approach can be provides the minimal effort in the implementation re-quired.

To get the basic data for the development of the method to diminsh the amount of disposed or dead storaged clothes by effective management or recycling of those clothes, in the view point of environmental protection, collegians clothing lifestyle was surveyed. The questionnaire included disposal means, and desirable disposal patterns of clothes in dead storage, awareness on the influences of clothing disposal on the environment, and so on. The final sample of 202 male and female collegians resulted from a sample of 300 Taejon residents. Data were collected during October of 1997 by respondents filling up. The results are follows: 1. Female bought clothes more on purpose than male. Also the low family income group and apartment residents bought clothes on purpose. 2. Regardless of sex and housing pattern, respondents took the most serious view of practical use in purchasing clothes. 3. Male usually kept the clothes in dead storage because of their unfittness for the body and deformation. On the other hand, out-of-date designs and colors and repugnance were the most frequent reason for dead storage. 4. The most popular pattern of the disposal of unattactive clothes was keeping those in wardrobe, regardless of sex, family income, and housing patter 5. More than half of the respondents thought that recycling or donation of dead storaged clothes to the neighbors, relatives, and public welfare facilities was the most desirable and environmentally affordable way of disposal in future.
