Because of the result of a large use of electronic equipments, the occupation density of microwave frequency band is highly increased, and electromagnetic environment is getting more seriously bad. It is sometimes reported that electronic machines are not normally operated on account of the influence of undesired electromagnetic wave, which often gives fatal blow to even human life and thus becomes serious social problems. OATS(Open Area Test Site) is principally used to measure EMI or examine elelctromagnetic emission. Because of various restrictions we often build semi-anechoic chamber which has the function of OATS to measure EMI or EMS other than OATS. If the difference of the site attenuation between semi-anechoic chamber and OATS is within ${\pm}3dB$, the semi-anechoic chamber is recognized as adequate facility to measure EMI or EMS. Accordingly authors evaluate and analyze site attenuation due to absorbent materials, polarization, mutual coupling effects, etc. The calculated and the measured site attenuation in semi-anechoic chamber are compared. As a result good agreement is obtained.

This study investigated the consumer acceptance process of the fourth industrial revolution new product to be introduced into the market in the future. The 4th Industrial Revolution new products are technological advances compared to the existing ones. The technology acceptance model that was used in the past has been modified to reflect variables like the social effects of the 4th Industrial Revolution, expected experience, and perceived risk. Modified models were proposed and verified. Six representative new products of the 4th Industrial Revolution were selected and examined by 40 respondents, and the hypotheses were verified using programs such as SPSS and AMOS. And conclusions and implications are as follows. First, the innovativeness of the fourth industrial revolution new products influences positive evaluation factors such as expected experience and perceived usefulness and it also affect positively to the perceived risk. In addition, the expected experience of the fourth industrial revolution new products has a great effect on the perceived usefulness and social influence, but it didn't affect to the perceived risk. Like the results of the TAM model, purchase intention of the fourth industrial revolution new products are strongly influenced by perceived usefulness. Finally, the perceived risk of the new product of the 4th Industrial Revolution had no statistically significant effect on the purchase intention, and the social influence of the 4th Industrial Revolution had a significant effect on the purchase intention. In general, respondents are highly aware of the social impact of the Fourth Industrial Revolution and seem to be very positive in this respect.

The successful aging paradigm suggests that the elderly keep their social ties and actively participate in various activities in later life. Many Korean studies on aging, however, have overlooked the importance of various social activities and relationships beyond kinship. This article aims to investigate the perceived social activities among Korean elders to comprehend the subjectivity of successful aging. 613 respondents, over 50 years old, are selected from a national survey data which was collected by face-to-face interview based on the structured questionnaire. The respondents are classified into pre old (50-64), young old (65-74), old old (over 75). Major findings are as follows. The social activities are grouped into two sub-categories: 'relational activity' and 'productive activity'. The activity types are different by the age cohorts. Various activities are considered in terms of one's needs or motivations, and properly chosen based on the subjective evaluation during life course. Both demographic variables such as sex, area and social context variables such as marital status, living-together show influence on the activity type choices. Plans for later life and work ethics are important as well. Policies regarding social participation emphasizing productivity should positively consider relational motives, as perceived by the Korean elderly.

In the rapidly developing information technology environment, information management organizations need to effectively evaluate their digital maturity and clarify the direction of improvement to effectively respond to rapidly changing environments. This study derived weights for the digital curation maturity model developed by KISTI from the perspective of digital transformation to facilitate effective evaluation and direction setting of information management organizations. Relative importance was derived as a weight in the major and middle categories of the model through the AHP technique. Summarizing the results, when the major categories of the entire model are measured on the basis of 100 points, technology is 27 points, data is 24 points, strategy is 19 points, organization (manpower) is 16 points, and (social) influence is calculated as 14 points. In addition, weights for each subcategory were presented for each major classification based on a perfect score of 100 points. It is expected that a more objective and reasonable evaluation will be possible by applying the weights for each area derived from this study to the digital transformation maturity evaluation model.

The purpose of this study was to verify the influence of musical activities on social and emotional behavior of infants, through providing musical activities to the infants who were cared in a nursery and observing the interactions between peer group, or a therapist and an infant derived during them. The subject is 24 infants who are under 2 years of age(25~36months) at two nurseries located in Bundang area, and 13 infants among them are randomly assigned as study group and 11 infants as control group. Pretest and posttest about social and emotional behavior are performed, and ITSEA developed by Brggs-Gowan and Carter(2001) and amended by Shin Ji Yeon(2004) was used as an evaluation tool. Infants' changes of interaction behaviors during musical play were also analyzed quantitatively and qualitatively, and for the analysis, infant's social play behavior examination tool developed by Holloway and Reichhart-Erickson(1988) was adopted. Based on time sampling method, each item of this tool was evaluated. Each session was performed for 15 minutes, and 60 times of analysis about interactions per session was conducted at every 15 seconds. The analysis result was showed with a table and a graph, and described qualitatively about behavior changes. When compared social and emotional positive behavior average figures and negative behavior average figures between study group and control group, this study showed that the positive behavior figure of study group was increased and the negative behavior figure was decreased. While concentration and empathy among positive behaviors increased meaningfully, aggression, defiance, separation anxiety and rejection to new things among negative activities also decreased meaningfully. The conclusion of this study is as follows. First, interactions with peers or a therapist based on music and musical experience make an effect on strengthening positive behavior among social and emotional behavior and decreasing negative behavior. Second, music has influence on negative behaviors more than positive behaviors of an infant, and produces a good effect on sub behaviors of negative behaviors specially.

An image exists in the thought of every subjective person and it exercises its influence over everything, having a great power in the real world. An positive image of the nurse has an influence on her faith, value and confidence, therefore increasing her job satisfaction, helping to upgrade her level of profession of nursing through qualitative nursing service as a result, considering the necessity of such an image when it comes to improvement of the profession, the confirmation of the image is indispensable to its evaluation of a speciality in nursing. This study is intended to help that improvement of the nursing profession in the present so that the total effort in every field of nursing is made and to offer basic material for developing a strategy to improve the image of nurses. This study is designed to investigate such an image descriptively. The subjects include 105 nurses, 60 doctors, 68 office workers, 88 medical engineers, 127 patients and there protectors with a total of 448 adapted with accidental sampling, who work at Y and W general hospital in Chonju. The measuring instrument consists of 40 question, with the researcher amended and made from on of Inja Song(1993), Donsoon Lee(1995), Ilsim yang(1998), and its Cronbach's alpha coefficient is .95. Data were collected from March 1 2000 to March 20, 2000 using self-reported questionnairs, analyzed with SPSS WIN 7.5 after encoding. The results are as follows: 1. Most of the subjects thinks the nursing as a hard, stressful, always busy job(more than 75%), and consider nurses as good-looking, supportive and responsible to co-workers to above average degree($50.0{\sim}74.9%$), especially it shows the idea that nursing is independently academic job and has come to fasten itself upon the public. But it shows below the everage($25.0%{\sim}49.9%$) in regard to self development as a specialist, affection for there job, an association activity, service to the community, high intelligence level and direct given patient nursing service. It also rated low as a recommendable job, independently nursing accomplishment, social position. 2. The nurses, patients and there protectors expressed more positive opinions than doctors, medical engineers, office workers about the image of the nurse(F=18.80, p=.00). This fact indicates that the former group evaluated the image similarly contrary to lowness of the latter. 3. In the study on what influenced upon the image, it defines to 79.8% by direct contact in the hospital or acquaintance with nurses, and 16.3% by mass media. 67.3% answered that they saw the image in a new light through hospitalization, which suggests an important source for the image management originates from caring for the quality of nursing service. Considering the evaluation of the image above, we need strategies to lead a unique professional knowledge and technological development, insurance of professional self-determination, high social position, participation in group activities, dedication to lifetime job, in order that nursing comes to expand as a professional occupation. Also, as for generating more positive images, we must take the quality of nursing service into account and offer and monitor correct information about the expanded role and function of the nurse continuously so that mass media reflect a more accurate image of nurses in general.

The jury instruction consists of a set of legal rules and provides a guide for jurors to interpret evidence and the legal standard of a proof beyond reasonable doubt. Jury instructions are usually given after the closing arguments (at the end of the trial). But some research has shown that jury instruction provided before the evidence may have an impact on verdict. The present study was to determine the cognitive process caused by early instruction: (1) Early instruction may influence the verdict by upwardly adjusting the threshold for the decision to convict; (2) early instruction may influence the verdict through evaluations of the probative values of evidence; (3) Or both. 187 people older than 20 years of age participated in the on-line survey. With a trial scenario, one independent variable, Instruction Procedure, was manipulated in three levels: before-and-after the evidence procedure, after-only evidence procedure, and no-instruction procedure. The instruction procedure conditions did not show any difference in the evaluation of the probative values of evidence. On the other hand, before-and-after condition showed the lowest rate of guilty verdict and the highest probability of guilt for the defendant in the scenario. This latter result clearly suggested that the instruction procedure affects the decision threshold. Specifically, instruction provided twice, once before and again after the evidence, may upwardly shift the threshold for the decision to convict.

Voters' negative evaluations of government performance lower their trust in government, which functions as the reward and punishment for the government. Trust in government thus serves to promote political accountability of the representative government. However, voters build their confidence toward the party government where the ruling party is responsible for the performance. Considering this partisan nature, we empirically examine that the influence of voters' performance evaluations on governmental trust is conditional on their party identifications. While higher perceptions of political/social conflict and increasing negative evaluations of government policies and economic performance are associated with the lower level of confidence in government, the relationship is contrasted between different party identifiers. For supporters of the ruling party in 2020, the negative evaluations of government performance are not likely to reduce trust in government a lot. On the contrary, those who identify with the main opposition party show the most prominent effect of negative evaluations on their distrust in government. This study demonstrates that trust in government is affected by voters' partisan preferences, not entirely by evaluations of government performance. Such a distortion of the reward and sanction function of governmental trust might lead to the weakening of the accountability mechanism in representative democracy.
