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.

Recently, the Ministry of Internal Affairs and Communications of Japan has reported on a plan for the "effective use of radio waves" to be promoted in the 2020s. This includes promotion of the effective use of public frequencies, reviews of frequency allocation and transition systems, and spectrum usage fee system. Based on the proposals in this study, concrete systems for revising related laws, such as the Radio Law, will be designed and implemented. In addition, the government will jointly conduct research and development as well as verification tests in cooperation with industry, academia, and government. A plan to improve the system for the effective use of radio waves will then be devised. This study examines the policy directions of the frequency utilization system that Japan plans to use for radio waves in the 2020s. The policy directions are analyzed selectively while considering the radio waves utilization system in Korea, and implications for domestic applications are derived. Based on the research from this study, analyzing the radio policies of advanced countries, including those of England and the United States, and utilizing them to establish an effective use plan of radio waves in Korea are deemed necessary.

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.

The purpose of this study was to investigate Korean undergraduate students' metacognitive awareness and preference of effective learning strategies. To achieve this goal, a scenario-based survey was conducted focusing on the metacognitive awareness, preference, and use of seven effective learning strategies (modality effect, static-media presentations, absence of extraneous details, testing, distributed learning, interleaved learning, generation) that were empirically supported. This study also aimed to explore the relationships between grade point average (GPA), metacognitive self-regulation, and the aforementioned variables to investigate which students know about, prefer, and use effective learning strategies. The majority of students were unknowledgeable about four of the seven strategies (modality effect, static-media presentations, absence of extraneous details, interleaved learning). Only half of the students were correctly aware of effectiveness of the two strategies (testing, generation). Moreover, students showed low preference for effective learning strategies. GPA did not show a significant correlation with metacognitive awareness and preference of effective learning strategies; however, it showed a significant positive correlation with the use of effective learning strategies. Only for a few learning strategies, metacognitive self-regulation showed a positive correlation with metacognitive awareness, preference, and/or their use. This study suggests that it is important to teach effective learning strategies to undergraduates with a specific direction of instruction. In addition, this study distinguishes metacognitive awareness from preference, suggesting that these two may reflect different constructs.

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.
