  • The purpose of the study is to predict the number of police calls using neural network which is one of the machine learning and negative binomial regression, by using the data of 112 police calls received from Chungnam Provincial Police Agency from June 2016 to May 2017. The variables which may affect the police calls have been selected for developing the prediction model : time, holiday, the day before holiday, season, temperature, precipitation, wind speed, jurisdictional area, population, the number of foreigners, single house rate and other house rate. Some variables show positive correlation, and others negative one. The comparison of the methods can be summarized as follows. Neural network has correlation coefficient of 0.7702 between predicted and actual values with RMSE 2.557. Negative binomial regression on the other hand shows correlation coefficient of 0.7158 with RMSE 2.831. Neural network has low interpretability, but an excellent predictability compared with the negative binomial regression. Based on the prediction model, the police agency can do the optimal manpower allocation for given values in the selected variables.

  • Purpose: This study was conducted to analyze the factors that influence the life satisfaction of the elderly according to their cognitive impairment level. Methods: This study was conducted by dividing 3,012 elderly residents of a regional community into three groups based on the scores of the Korean version of the Mini-Mental State Examination: a normal group without any cognitive impairment, a suspicious group with a mild level of cognitive impairment, and a high risk group with a high level of cognitive impairment. Researchers made phone calls, house calls, and personal visits to health centers and shelters for the elderly to gather the information required for this study. Results: The results of this study revealed that social relationships, depression, and activities of daily living had a significant impact on life satisfaction for the normal group, while social relationships and depression had a high impact on life satisfaction for the suspicious group, and social relationships had high impact on the life satisfaction of the high risk group. Conclusion: Based on the results of this study, we suggest that programs that promote development of the social relationship networks of the elderly should be established to promote their life satisfaction.

  • Scholars have considered Chaucer's House of Fame mostly as an ars poetica, in which the poet explores new poetic principles and subject matters, while making few attempts to understand the poem in its historical and social contexts. Investigating the nature of the "tidings" that Chaucer suggests as the new source of his poetic inspiration, this paper argues that the house of Rumor was modeled after late fourteenth century English society that experienced increased appetite for news. The political upheaval during the period from the English Rising in 1381 to the reign of Henry IV in the early fifteenth century produced an unprecedented amount of written and oral propaganda. The proliferation of seditious rumors as well as protests and promulgations during this period indicates how seriously medieval society was engaged with the circulation of news. Particularly, the case of John Shirle in 1381 and the legend about the survival of Richard II demonstrate the subversive power of medieval rumor that often served as a political discourse with which people expressed their oppositions to government. Conspicuous in the activities of both the government and late medieval political protestors was the extensive use of writing. The posting of bills in public places continued until the fifteenth century, when such activities became so common and dangerous that the government had to issue proclamations forbidding the circulation of such seditious writings. The number of extant royal proclamations, written protests, and pamphlets demonstrates that already in the late fourteenth and fifteenth centuries the notion of a discursive public space began to emerge. Whether written or orally transmitted, news and rumor circulated in late medieval England, creating a social space in which people shared their political opinions before the introduction of the early modern print culture. In The House of Fame Chaucer calls attention to the subversiveness of rumor, its potential as a public discourse, and the power of written communication in creating truth in order to appropriate these characteristics for his English poems.

  • Today, the number of the elderly living alone without any family members is on a sharp rise, and those aged people living alone are making these social issues such as solitary death, depression and suicide more popular. In order to resolve the issues, some of the local governments have been supporting the elderly living alone in common houses that would be used by senior citizens only. This study became interested in this 'carnation house' which has been carried out targeting the elderly living alone in Gyeonggi-do, and selected elementary universal design factors that should be applied to general residential environments of the aged people and analyzed the factors. As a case study, this research investigated four carnation houses as research subjects and came up with these following ideas about how to make improvements. First, the study found out that all the entrances did not have raised letters and that UD has not been satisfactorily applied to both the thresholds and the effective widths, and that is considered something to be fixed. Second, in case of regular rooms and living rooms, none of the rooms failed to have safety doorknobs which should have been installed and plus, thresholds and stepped pulleys need to be removed, Third, it goes the same with the kitchens, and the thresholds should be eliminated while cabinets are secured. In addition, furniture that understands the elderly's measurements should be used. Fourth, in terms of restrooms, they should be designed to be spacious enough not to cause anyone in wheelchairs inconvenience, and the study suggests that the effective widths should be widened and that both the safety doorknobs and the emergency calls must be installed. Basically, after the test on the UD adaptability, the study concluded that the application rates in connection with the adaptability were low which led the study to assume that such result has been gained due to the lack of installation standards in relation to the common living facilities of the elderly. The study now argues that purposes of buildings should be first clarified and then, these detailed space planning guidelines that deal with general characteristics of the aged people should be established.

  • The possession rate of residential telephones tend to decrease as mobile phones are widely spread. There is also a decrease in the access rate of the qualified respondents due to the low rate of phone book registration and that of house owner's presence at home. Such a change in telephone survey environment calls for another survey-channel which makes good use of new telecommunication services. In this paper, a mobile survey system was designed and performed by the use of SMS (Short Message Service) which is a kind of mobile data communication service. The system draws the sample by using random digit sampling based on 'quota allocation', and sends the SMS to the sample according to the arranged scheduler. Then, the survey-panel which received the SMS connects to the responding server by pressing the 'send' button (which is connected by the callback number), responding to the question. As a result, the responding value is stored in the database and is analyzed in real-time. This system is distinguished from other research methodologies for its simplicity in data collection, its inexpensive research price, and the innovatively low research time.
