Purpose The research on the effective use of IS needs to embrace the alignment to organization learning process, which expands the limited focus on dynamic capability of IS use. In addition, it should be done in multi-level analysis with system, user, task, and organization. The current study suggests the inclusion of multi-level analysis of effective use of IS in the perspective of exploration and exploitation. Design/methodology/approach This review selected the representative studies in IS discipline which have investigated the effective use of IS, dynamic capability, operational capability, exploration, exploitation, or organizational learning. In the search of academic archives with those keywords, seventeen papers which have been most cited were chosen and validated whether the focus constructs are directly theorized or validated the suggested keywords. In addition, the level of analysis was verified whether it includes one or more levels of system, individual, task, or organization. Based on the initial analysis of dynamic capability, the further review of research on explorational and exploitational capabilities was implemented. Findings The present review study on previous literature on effective use of IS presented that it is largely implemented in the level of individual but few of them has included organization level. Similarly, the direct investigation of explorational and exploitational use of IS has not been done so much. The needs of study on effective use of IS in depth have been inquired for a decade. However, the review presented that it still lacks profound theories and empirical validations compared to those of adoption stage of IS. Based on the review, future research on the transition between explorational and exploitational use of IS is suggested.

최근 일본에서는 공공용 주파수의 유효이용촉진, 주파수 할당 이전제도와 전파사용료제도 재검토 등을 포함하여 2020년대에 추진할 예정인 "전파유효 이용방안"을 보고서로 발표하였다. 이 보고서에서 제안된 내용을 기반으로 전파법 등 관련법령 개정을 위한 구체적인 제도가 설계되어 진행될 예정이며, 산 학 관이 협력하여 연구개발 실증시험 등을 실시하여 전면적인 전파유효이용을 위한 제도개선을 추진할 계획을 수립할 예정이다. 본 논문에서는 일본이 2020년대에 전파유효이용을 위해 추진할 예정인 주파수 이용제도에 관한 정책방향을 분석하였다. 분석된 정책방향은 국내 전파이용제도를 고려하여 선별적으로 검토하였으며, 국내에 적용할 수 있는 시사점을 도출하였다. 본 논문의 연구내용을 바탕으로 영국과 미국을 포함한 선진국의 전파정책을 분석하여, 우리나라의 전파유효 이용계획수립에 활용하는 것이 필요하다.

The purpose of this paper is to analyze the actual condition, the result and the problem of the military defense CALS system and seek the way of the effective use of the military defense CALS. We perform an analytic hierarchy process to find the factors that have an influence on the effective use of CALS and evaluate the level of importance of these factors. Also we estimate the actual condition and the result by the Likert 7 scale.

Tobacco has become the world's leading cause of deaths and diseases. And !be tobacco use and dependence itself is a kind of diseases, so-called "mental and be-havioural disorders due to use of tobacco" in "International Statistical Classification of Diseases and Related Health Problems(ICD-10)" and "Korean Standard Classification of Diseases". The tobacco use and dependence is a chronic disease that requires repeated clinical interventions and multiple attempts to quit. But effective treatments to the tobacco use and dependence are developed and exist that can significantly increase the rate of long-tenn smoking abstinence. So the physicians should warn smoking patients about the dangers of smoking to the health and the life, and the clinicians ought to provide one of more of the treatments which have been proven effective in helping smokers quit to smoke. It has been concluded that if a doctor failed to provide effective treatment for smokers, and the smokers subsequently died of the smokers-related conditions(tobaccosis) or became incapacitated by the tobaccosis the smokers were considered in the medical malpractice. Thus the smokers could sue the physician for medical malpractice, claiming that the doctor's legal responsibility of appropriate treatments including smoking-cessation which the physician deliberately or negligently breached.

The evaluation of the effective rainfall is important in the desgin and operation of irrigation systems. But the difinition of the effective rainfall and the method for the estimating effective rainfall is various for each purpose . In this paper, the effective rainfall was defined as amount of rainfall which is remained in the effective soil depth that can be use to consumptive use of crop during growing season. The sol moisture was measured by Neutron prob for the effective rainfall estimation, and theexperiment was conducted for mulched and non-mulched condition of lysimeter during growing season. By the result of analysis and the former definition, the effective rainfall was estimated to be 37.2% for the mulched lysimeter and 40.7% for the non-mulched lysimeter.

In this study, We peformed on the effective evaluation of slope berm construction using slope stability analysis programs. The effective evaluation of slope berm construction was performed by stability of slope and economy of construction. This time, used slope stability analysis programs are Talren97 that use Limit equilibrium method (LEM) and FLAC-SLOPE that use finite difference method (FDM), and carried out using Rocfall program to evaluate slope stability by rockfall occurrence.

본 연구는 국내 대학생이 효과적인 학습전략을 얼마나 잘 알고 있고, 선호하는지 살펴보고자 하였다. 이를 위해 선행 연구에서 검증된 7개 중요 학습전략(정보양식효과, 정적매체학습, 매력적인 군더더기 부재학습, 시험, 분산학습, 교차학습, 생성학습)을 정리하고 이에 대한 효과성 인지, 선호, 활용을 묻는 시나리오 기반 설문을 구성하였다. 이와 함께 학점과 메타인지적 자기조절을 측정하여 어떤 학생들이 효과적인 학습전략을 잘 알고, 선호하고, 활용하는지 알아보고자 하였다. 연구 결과, 4개 전략(정보양식효과, 매력적인 군더더기 부재학습, 정적매체학습, 교차학습)에 대해서는 대다수의 학생이 학습전략의 효과성을 잘 모르고 있었으며 2개 전략(시험, 생성학습)에 대해서도 절반가량의 학생만이 그 효과성을 제대로 인지하고 있었다. 또한, 국내 대학생은 효과적인 학습전략에 대해 낮은 선호도를 보였다. 학점은 학습전략에 대한 효과성 인지 및 선호와는 유의한 상관을 나타내지 않았으나, 활용과는 유의한 정적 상관을 보였다. 메타인지적 자기조절은 일부 학습전략에 한하여 효과성 인지, 선호 및 활용과 정적 상관을 보였다. 본 연구결과는 대학생에게 효과적인 학습전략에 대한 교수가 필요함을 시사하며 그에 대한 구체적인 방향성을 제시한다는 점에서 의의가 있다. 또한 본 연구는 학습전략에 대한 효과성 인지와 선호를 구분하여 살펴보았으며, 두 변인이 서로 다른 구인일 가능성을 제시하였다.

Amount of radiation exposure by seeing through fluoroscopy examination while is many patient exposure administration and unprepared misgovernment be. In this study, abdominal fluoroscopy during the scan, the dose and image quality change according to the use of grid and added filter optimized by measuring the test condition is proposed. Uses seeing through fluoroscopy examination equipment of Image Intensifier of Easy Diagnost Eleva (Philips), under tube type and uses Human phantom and measures average area dose according to grid insertion existence and nonexistence and added filter kind change. Measure sum of 29 organ dose and effective dose through PCXMC imagination simulation program and image J program through noise, SNR, image distortion was measured. Resolution, sharpness, and analyzed using the MTF curves. Fluorography the grid to insert the filter thickness and thickening and increased the average area dose and organ doses and effective dose. In the case of spot examination, when inserted grid, average area dose and organ dose and effective dose increased. Filter thickens the average area dose decreased, but the organ doses and effective dose were increased when use 0.2mmCu+1mmAl filter, decreased slightly. Noise and SNR measurements without inserting the gird, if you do not use the added filter was the lowest and when measure the distortion, 0.1mmCu+1mmAl filter was no difference of image quality in case insert grid was judged that when did not use occasion added filter that do not use grid, difference of image quality does not exist. Did not show a big difference, according to the grid and uses of the added filter sharpness, and resolution. Patient dose increases with factors that reduce the quality of the image so reckless grid and the use of the added filter when abdominal fluoroscopy examination should be cautious in using.

The improved accuracy of the Land Cover/Land Use Map constructed using Hyperspectal Satellite Image and the possibility of real time classification of Land Use using optimal Band Selective Factor enable the change detection from automatic classification using the existed Land Cover/Land Use Map and the newly acquired Hyperspectral Satellite Image. In this study, the effective analysis techniques for automatic generation of training regions, automatic classification and automatic change detection are proposed to minimize the expert's interpretation for automatic update of the Land Cover/Land Use Map. The proposed algorithms performed successfully the automatic Land Cover/Land Use Map construction, automatic change detection and automatic update on the image which contained the changed region. It would increase applicability in actual services. Also, it would be expected to present the effective methods of constructing national land monitoring system.
