Current landscape management is focused towards managing uniformly, such as setting a limit on building's height and managing by putting first priority on building. For this reason, broader impact of landscape has not been studies thoroughly, and it was considered to be an important factor of not being able to operate diverse and active landscape management. Accordingly, the objective of this particular research to establish concrete and diverse device for managing landscape by adapting Map Algebra and Spatial Statistics, as one of the means of efficient landscape management, and applying the effectiveness of each landscape element in numerical value. Furthermore, this research was done in order to make a spatial estimation possible for resources to be located in compliance with each facility or landscape condition of individual region.

The conventional computing is a centralizing system, but it has been gradually going to develop ubiquitous computing which moves roles away from the main. The Community Computing, a new paradigm, is proposed to implement environment of ubiquitous computing. In this environment, it is important to accept the user demand. Hence in this paper recognizes pattern of user's activity statistically and proposes a method of pattern estimation in community computing. In addition, user's activity varies with time and the activity has the priority We reflect these. Also, we improve accuracy of the method through Knowledge Base organization and the feedback system. We make program using Microsoft Visual C++ for evaluating performance of proposed method, then simulate it. We can confirm it from the experiment result that using proposal method is better in environment of community computing.

본 논문은 광대역 무선 통신망의 물리계층 OFDMA시스템 구조에서 멀티미디어 패킷 서비스의 효율적인 처리를 위한 스케줄링 알고리즘을 제안한다. 스케줄링 알고리즘은 무선 채널 상태 정보 추정을 이용하고 클래스 및 우선권 정책 기반 전송 순위 결정과 이에 의한 전송률 할당을 한다. 그 결과로 제안된 스케줄링 알고리즘은 실시간 서비스에 대해선 최대 트래픽 처리량과 jitter의 최소화를 만족하고 비실시간 서비스에 대해 공평한 트래픽 처리를 수행한다. 제안 된 스케줄링 알고리즘은 기존의 라운드 로빈 스케줄링 방식과 시뮬레이션을 통한 비교를 통해서 보다 우수한 성능을 보인다.

무선 멀티홉 네트워크에서 멀티미디어 트래픽의 QoS(Quality of Service) 지원을 위하여 EDCA(Enhanced Distributed Channel Access) 기반의 동적 우선순위 할당 기법이 다수 제안되었다. 해당 기법들은 각 홉에서의 최소한의 전송 지연 보장을 위하여 클래스별 예상 지연 시간을 계산한다. 하지만 각 클래스별 예상 지연 시간의 계산은 무선 채널에서의 간섭, 충돌 및 링크 품질에 영향을 받기 때문에 정확한 예측이 어렵다. 본 논문에서는 EDCA 기반의 동적 우선순위 할당을 위한 정교한 클래스별 지연 시간 예측 기법을 제안한다. 제안하는 기법은 무선 채널의 링크 품질과 전송 패킷의 크기를 고려하여 좀더 실제와 유사한 지연 시간을 예측할 수 있다. 실험을 통해 제안하는 기법이 기존의 기법보다 정확성이 높으며 이를 통해 동적 우선순위 할당 기법의 성능을 향상시킬 수 있음을 확인하였다.

Certification about management innovation business (Mainbiz) was added in 2006 newly along with existent technical innovation business certification (Innobiz) and venture business certification with government's policy connected with reform style small and medium enterprises 30 thousand upbringings. Drew dividing management innovation business evaluation figure by manufacturing industry and service industry through leading study, gives weight by industry about drawn evaluation figure and must give estimation point of suitable level. This studies judge importance about evaluation figure by industry and consider priority order by evaluation figure using AHP (Analytic Hierarchy Process) that use expert group and gave point.

본 논문에서는 IIoT 환경에서 중요한 비정상적 데이터 수집을 위한 노드 우선순위 선정 모델을 제안하였다. 제안하는 모델은 비정상적 데이터 수집과 다른 노드로 부터의 정상 데이터의 수집 격차를 적절히 조절하기 위하여 Fair and Delay-aware Cross-layer(FDRX) 기법과 데이터 Classification 기법을 이용, 데이터의 긴급성과 네트워크 환경을 분석하여 노드를 평가한다. 이를 통하여 IIoT 환경에서의 데이터 분석에 중요한 비정상적 데이터를 원활하게 수집하면서도 다른 노드와의 전송 격차를 줄일 수 있을 것으로 기대된다.

This study analyzed relation with risk recognition degree by customs business of customs brokers and actuality insurance accident occurrence. These study finding that risk recognition by customs work area of customs brokers and actuality insurance accident occur did not agree. So customs brokers more elevate risk recognition of entry field, origin/trademark right, HS and customs tariff application, customs refund, price estimation that are high the insurance accident rate. and they may have to do emphasis administration through employee education and ability elevation. Specially, operation risk that is produced from charge employee's simplicity mistake who tax invoice omission, a tax use mistake, document nondelivery, notice dispatch delayed action, may have to manage through moral management and employee bylaws and education, employee guidance etc. Also, they publicize these contents to import and export enterprise, and practice risk management of high risk business in priority through education and public information. so we will have to make can do more effective risk management.

Demand for manpower of conducting pharmaco-economic evaluation was investigated. The priority order of conducting economic evaluation on the already listed drugs was set by the budget impact for health insurance by the therapeutic groups. Manpower demand was estimated by the Anatomical, Therapeutical, Chemical (ATC) code. The total number of economic evaluation on the already listed drugs is estimated to be 346 cases. Based on these numbers, at least 53${\sim}$102 of full-time-equivalent (FTE) manpower is needed for conducting economic evaluation per year in the following 5 years.

The persistence of the employment shock by COVID-19 has various policy implications during the pandemic and beyond it. After evaluating the impact of the health crisis at the individual level, this study decomposes employment losses into persistent and transitory components using the observed timing of the three major outbreaks and subsequent lulls. The estimation results show that while face-to-face services were undoubtedly hit hard by the COVID-19 crisis, the sectoral shock was less persistent for temporary jobs and self-employment. Permanent jobs in the hard-hit sector showed increasingly large persistent losses through the recurring crises, indicating gradual changes in employer responses. The persistent job losses were concentrated on young and older workers in career transitions, whose losses are likely to have long-term effects. These results suggest that targeted measures to mitigate the persistent effects of the employment shock should take priority during the recovery process.
