This study investigated the information needs of prisoners and the adequacy of information resources in prison libraries in Anambra State, Nigeria. Two research questions guided the study. The population of the study was 1781 inmates in prisons in Anambra State. The sample size of 327 was selected using Taro Yamane's formula and proportionate stratified sampling techniques. Two instruments titled the Information Needs of Prisoners Questionnaire and the Adequacy of Information Resources Checklist were used for data collection. The instruments were validated by three experienced lecturers. One in the department of Educational Foundations (Measurement and Evaluation Unit) and two in the Department of Library and Information Science, all at Nnamdi Azikiwe University, Awka. Cronbach's alpha was used to determine the internal consistency of the questionnaire items, with a value of 0.79. The researchers administered the questionnaires with the help of four research assistants (correctional officers). Out of 327 questionnaires administered, 314 were successfully retrieved. The percentage return rate of distributed questionnaires is 96%. Data collected were analyzed using descriptive statistics of the mean; also, the International Federation of Library Association (IFLA) guideline for library services to prisoners was also used as a yardstick for the measurement of adequacy. The results from the data analysis indicated that prisoners have diverse information needs that, when met, would help them during their stay in prison as well as when they are eventually released; these needs include legal information, information on prison rules, financial information, and others. While there were few information resources found to be adequate, the inadequacy of most of the listed information resources is recorded in prison libraries in Anambra State, Nigeria. It is therefore recommended that information resources be made adequately available for prisoners in relation to their information needs.

We investigate the test for model adequacy in nonlinear regression. We can expect the usual likelihood ratio statistic to be unaffected by any parametric- effect curvature; only the effect of intrinsic curvature needs to be considered. Multiplicative correction factor is derived for the limiting distribution of test statistic, which is a function of the intrinsic curvature arrays.

The purpose of this study is to propose evaluation factors for elementary school facility in terms of educational adequacy. The focal point of this study is to clarify the proper measure of educational facility evaluation in the light of specific characteristics of facility. In order to improve the level of educational adequacy, more information is needed regarding school facility design and various factors which affect to the design. This is important works because such information is essential in implementing facility design to meet the needs of the new educational policy. To get the goal, first, it is attempted to analyse the meaning of design information which deeply affect on the school facility design. The design information is classified into three main aspects, such as human aspect, social aspect and physical aspect. The design information regarding the physical space verses human psychology and behavior belongs to category of human aspect. Pedagogic ideology which varies depend upon the time and regions is classified into the category of social aspect. The Physical aspect means efficient equipment performance of space to support educational activities effectively. Secondly, as for the educational adequacy evaluation concern, it is attempted to select more items which usually has been neglected by the existing evaluation criteria which mainly emphasized functional performances only. With the premise of the above, in this paper, it is attempted to propose proper evaluation factors in terms of educational adequacy for school facilities. As the research methods, researching of literature on this subject, field trip, interview, site analysis, and survey is used.

This study draws important factors in electronic Word-of-Mouth (eWOM) and examines how these influence the building of customer loyalty. eWOM is viewed as social communication between customers and sellers, and thus the communicative action theory is applied. With the theory, we identify reviewer and seller as influential players on customers, and derive important factors such as correctness and veracity of reviews from the reviewers' action, and information compactness and adequacy from the seller's action. We propose these constructs as antecedents of customer loyalty and further hypothesize their curvilinear impacts as follows: the marginal impacts of veracity and correctness will decrease as veracity and correctness increase, and the marginal impacts of compactness and adequacy will increase as compactness and adequacy increase. The result indicates that only the seller's action has a curvilinear impact, whereas the reviewer has proportional positive impact on customer loyalty. This study indentifies important factors in eWOM from a critical social theory perspective and validates them using the positivistic approach. For practitioners, it discusses the important factors in eWOM with the identification of the individuals who are responsible for these factors.

As the complexity of software is increasing, generating an effective test data has become a necessity. This necessity has increased the demand for techniques that can generate test data effectively. This paper proposes a test data generation technique based on adequacy based testing criteria. Adequacy based testing criteria uses the concept of mutation analysis to check the adequacy of test data. In general, mutation analysis is applied after the test data is generated. But, in this work, we propose a technique that applies mutation analysis at the time of test data generation only, rather than applying it after the test data has been generated. This saves significant amount of time (required to generate adequate test cases) as compared to the latter case as the total time in the latter case is the sum of the time to generate test data and the time to apply mutation analysis to the generated test data. We also use genetic algorithms that explore the complete domain of the program to provide near-global optimum solution. In this paper, we first define and explain the proposed technique. Then we validate the proposed technique using ten real time programs. The proposed technique is compared with path testing technique (that use reliability based testing criteria) for these ten programs. The results show that the adequacy based proposed technique is better than the reliability based path testing technique and there is a significant reduce in number of generated test cases and time taken to generate test cases.

This paper reviews the categories and properties of risk measures, analyzes the classes and structural equations of volatility forecasting models, and presents the practical methodologies and their expansion methods of estimating and forecasting the volatilities of exchange rates using Excel spreadsheet modeling. We apply the GARCH(1,1) model to the Korean won(KRW) denominated daily and monthly exchange rates of USD, JPY, EUR, GBP, CAD and CNY during the periods from January 4, 1998 to December 31, 2009, make the estimates of long-run variances in the returns of exchange rate calculated as the step-by-step change rate, and test the adequacy of estimated GARCH(1,1) model using the Box-Pierce-Ljung statistics Q and chi-square test-statistics. We demonstrate the adequacy of GARCH(1,1) model in estimating and forecasting the volatility of exchange rates in the monthly series except the semi-variance GARCH(1,1) applied to KRW/JPY100 rate. But we reject the adequacy of GARCH(1,1) model in estimating and forecasting the volatility of exchange rates in the daily series because of the very high Box-Pierce-Ljung statistics in the respective time lags resulting to the self-autocorrelation. In conclusion, the GARCH(1,1) model provides for the easy and helpful tools to forecast the exchange rate volatilities and may become the powerful methodology to overcome the application difficulties with the spreadsheet modeling.

Background & Objectives : Korea is face with the social need for health care technology assessment so that it is urgently needed to found principles and methodology in technology assessment in health care. As a groundwork for health care technology assessment, we tried to prioritize medical technology for assessment. Among medical technologies, procedure is somewhat difficult to assess, compared to drug or equipment. In this study, we aimed at the prioritisation of medical procedure to be assessed, in terms of efficay, safety, and adequacy. Method : For the standardized classification of medical procedure, ICD-9-CM(International Classification of Diseases 9th edition - Clinical Modification) was used. Among the list the procedures coming under otorhinolaringjology and thoracic surgery were selected by three family physicians. The list of procedure was mailed to the board certified surgeons of both disciplines, with the question asking about the necessity for assessment in terms of efficay, safety, and adequacy. Replied questionnaires were analyzed in each procedure. Results : Of 560 otorhinolaryngologist and 480 thoracic surgeon, 114 surgeons replied. Of otorhinolaryngological procedure, incision, excision, and destruction of inner ear : fenestration of inner ear : stapedectomy and its revision were the most urgent technology to assess in the aspect of safety. For adequacy, operations on Eustachian tube: fenestration of inner ear: incision, excision, and destruction of inner ear were highly ranked in necessity, and for efficary, operations on Eustachian tube; external maxillary antrotomy; fenestration of inner ear. Thoracic surgeons replied thoracic procedures, lung transplantation; heart transplantation; implantation of heart assist system [pump] are most important for evaluation in terms of safety; and heart transplantation; Lung transplantation; Implantation of heart assist system [pump] in terms of adequacy, and surgical collapse of lung [Artificia니 pnemothorax or pnuexoperitoeum]; lung transplantation; periarterial sympathectomy in terms of efficacy. As a whole, surgeons regard safety evaluation is more urgent than adequacy or efficary. In addition, otorhinolaryngological surgeons regard evaluation of their procedures more urgent than thoracic surgeons regard theirs. Conclusion : By the questionnaire to board certified physicians, we get some preliminary data for prioritisation of technologies to assess. Through the questionnaire like this, much information would be gathered for technology assessment, especially for medical procedure, if not enough. In the near future, well structured expert opinion gathering research, such as modified Delphi or nominal group technique, should be done succeedingly.
