This research aimed to examine an advertising location according to consumer involvement about internet search advertising and advertising effect according to advertising forms. This research carried out a questionnaire survey from May 25, 2011 for seven days with the target of men and women at the age of 20s-30s who tried search advertising in Seoul and capital area, and 519 copies were used for final analysis. For analysis of collected materials, the reliability test, factor analysis, $t$-test, regression analysis and ${\chi}^2$ test were executed by using statistical package SPSS 16.0. The results are as follows. First, it appeared that consumer's clothing involvement, advertising involvement, advertising location and advertising forms had an influence on site attitude and clicking intention. Consumers of high clothing involvement, high advertising involvement and upper end advertising appeared to have high site attitude and clicking intention. Second, all consumers of the low and high clothing involvement and upper end advertising appeared to prefer the upper end advertising. It appeared that consumers of low advertising involvement prefer lower end advertising, and consumers of high advertising involvement prefer the upper end advertising at an advertising location according to clothing involvement. Accordingly, it is important that the search advertising exposes advertising in the upper end, and that should use an advertising phrase capable of giving trust to consumers. As the text advertising had high site attitude and clicking intention in the advertising forms, consumers should pay attention to the advertising phrase.

In order to achieve success in ground operations, searching for moving targets is one of critical factors. Usually, the system of searching for adversary ground moving targets has complex properties which includes target's moving characteristics, camouflage level, terrain, weather, available search time window, distance between target and searcher, moving speed, target's tactics, etc. The purpose of this paper is to present a practical quantitative method for effectively searching for infiltrated moving targets considering aforementioned complex properties. Based upon search theories, this paper consists of two parts. One is infiltration route analysis, through terrain and mobility analysis. The other is building dynamic probability maps through Monte Carlo simulation to determine the prioritized searching area for moving targets. This study primarily considers ground moving targets' moving pattern. These move by foot and because terrain has a great effect on the target's movement, they generally travel along a constrained path. With the ideas based on the terrain's effect, this study deliberately performed terrain and mobility analysis and built a constrained path. In addition, dynamic probability maps taking terrain condition and a target's moving speed into consideration is proposed. This analysis is considerably distinct from other existing studies using supposed transition probability for searching moving targets. A case study is performed to validate the effectiveness and usefulness of our methodology. Also, this study suggests that the proposed approach can be used for searching for infiltrated ground moving target within critical time window. The proposed method could be used not only to assist a searcher's mission planning, but also to support the tactical commander's timely decision making ability and ensure the operations' success.

Recently, Genetic Algorithm(GA) is widely adopted into a search procedure for structural optimization, which is a stochastic direct search strategy that mimics the process of genetic evolution. This methods consist of three genetics operations maned selection, crossover and mutation. Contrast to traditional optimal design techniques which use design sensitivity analysis results, GA, being zero-order method, is very simple. So, they can be easily applicable to wide area of design optimization problems. Also, owing to multi-point search procedure, they have higher probability of converge to global optimum compared to traditional techniques which take one-point search method. In this study, a method of finding the optimum values of suspension parameters is proposed by using the GA. And vehicle is modelled as planar vehicle having 5 degree-of-freedom. The generalized coordinates are vertical motion of passenger seat, sprung mass and front and rear unsprung mass and rotate(pitch) motion of sprung mass. For rapid converge and precluding local optimum, share function which distribute chromosomes over design bound is introduced. Elitist survival model, remainder stochastic sampling without replacement method, multi-point crossover method are adopted. In the sight of the improvement of ride comfort, good result can be obtained in 5-D.O.F. vehicle model by using GA.

Recently, Genetic Algorithm(GA), which is a stochastic direct search strategy that mimics the process of genetic evolution, is widely adapted into a search procedure for structural optimization. Contrast to traditional optimal design techniques which use design sensitivity analysis results, GA is very simple in their algorithms and there is no need of continuity of functions(or functionals) any more in GA. So, they can be easily applicable to wide area of design optimization problems. Also, owing to multi-point search procedure, they have higher porbability of convergence to global optimum compared to traditional techniques which take one-point search method. The methods consist of three genetics opera- tions named selection, crossover and mutation. In this study, a method of finding the omtimum size and topology of drilling machine is proposed by using the GA, For rapid converge to optimum, elitist survival model,roulette wheel selection with limited candidates, and multi-point shuffle cross-over method are adapted. And pseudo object function, which is the combined form of object function and penalty function, is used to include constraints into fitness function. GA shows good results of weight reducing effect and convergency in optimal design of drilling machine.

본 논문에서는 다중 참조영상에 적용을 위한 고속 움직임 추정 (motion estimation) 알고리즘을 제안한다. 우선 전역움직임추정방법(full search)의 고속 알고리즘인 연속 제거 알고리즘(successive elimination algorithm)을 다중 참조영상(multi-reference frames)에 적용하였을 때의 결과를 분석하고, 이를 바탕으로 계산량 감축 방안을 제안한다. 제안된 방법은 바로 이전 영상에 대한 움직임 벡터를 연속 제거 알고리즘을 적용하여 추출하고, 그 외의 참조영상에 대해서는 이전 영상에서 얻어진 움직임 벡터를 기반으로 외삽(extrapolation)을 수행함으로써 추정한다. 이 추정된 벡터를 중심으로 탐색범위를 적응적으로 제한함으로써 화질 저하를 최소화시키면서 계산량을 크게 감축하도록 제안하였다. 실험을 통해 제안된 방법의 성능을 분석하고 검증하였다.

현재 경찰과 소방이 범죄신고, 긴급출동과 같은 구조 상황발생 시 통화권영역 내에서는 이동통신 사업자가 구축한 네트워크,와이파이,GPS기반의 긴급 구조용 측위시스템을 활용하여 요구조자의 단말과 직접 연동하여 예상위치를 정밀 측위를 하고 있다. 그러나 산악구조의 경우 조난자가 산악지형의 음영지역에 위치하거나 단말의 방전(power off) 시에는 단말과 직접 연동하여 정밀 측위가 불가능하며 마지막 접속 기지국 정보만을 받고 있어 수색의 위치를 한정할 수 없으므로 구조 골든타임 확보가 어려운 상황이다. 본 논문에서는 개선방안으로 시계열 기지국 정보, 위치정보 및 조난자의 성별, 나이, 행동적 특성을 반영한 이동성 모델과 지능형 추론을 기반으로 하는 전파분석 및 위치추정 시뮬레이션과 같은 이동통신 포렌식 기술을 통해 조난자의 예상 위치정보의 확률에 따른 히트맵 방식의 시각화를 통해 위치정보의 정확성을 높여 소방, 수색대의 수색지역을 축소하여 신속하고 정확한 인명구조에 기여할 수 있기를 기대한다.
