A model was developed for a simple clinical trial in which graders had defined probabilities of misclassifying pathologic material to disease present or absent. The authors compared Kappa between graders, and efficiency and bias in the clinical trial in the presence of misclassification. Though related to bias and efficiency, Kappa did not predict these two statistics well. These results pertain generally to evaluation of systems for encoding medical information, and the relevance of Kappa in determining whether such systems are ready for use in comparative studies. The authors conclude that, by itself, Kappa is not informative Enough to evaluate the appropriateness of a grading scheme for comparative studies. Additional, and perhaps difficult, questions must be addressed for such evaluation.

Vibrations on the floor in a car are transmitted to the foot, hip, and back from the seat. Human body recognizes these vibrations, but the sensitivity for each vibration is different. To evaluate these vibrations, RMS(root mean square) of accelerations, VDV(vibration does value) are commonly used. The ride comfort evaluation is usually carried out by experiments of real cars which are expensive. The purpose of this paper is to briefly review the status of several ride vibration standards and criteria having relevance to construction machinery vehicles and to suggest recommendations for the effective use of such criteria in vehicle / component development.

Community-Based Participatory Research(CBPR) has gained attention as a public health approach to develop community health interventions to address health disparities in recognition of the community relevance of specific health issues associated with social determinants of health. It emphasizes community involvement in equal partnership with researchers and public health professionals to address community-identified needs. The characteristics and principles of CBPR discussed in this paper highlight participatory nature, capacity development, partnership building, and process-orientation of CBPR. A 6-step process model for community empowerment is then introduced as a CBPR operationalization strategy. Mixed methods research approaches are valuable in CBPR as well as process evaluation. For the application of CBPR in Korean contexts, the Diffusion of Innovation theory is suggested as a theoretical framework for implementation. Building public health partnerships between public and private sectors to create partnership synergy is a necessary condition for successful CBPR for health promotion in Korea. Accompanying critical factors for the CBPR application include: common understanding of CBPR and its values, establishment of the definition of 'community,' 'community-based' and 'participation' in community health, development of accommodating research infrastructure for CBPR, recognition of the importance of program evaluation (particularly process evaluation), and training CBPR specialists.

This study reviews studies that used skin temperature in order to establish an emotion evaluation protocol based on skin temperature for home appliances. A survey of skin temperature evaluation papers was conducted by the following five stages: (1) keyword search, (2) title screening, (3) abstract screening, (4) full paper screening, and (5) relevance evaluation. Selected papers were reviewed for: purpose, recruitment criteria of participants, the number of participants, apparatus, procedure, measures, analysis methods, and major findings. Thermistor sensors and thermography are used for the measurement of skin temperature. Skin temperature sensors are attached to 4 - 10 locations on the body and their mean of skin temperature is calculated by Ramanatan's 4-point or Hardy & Dubois's 7-point method. Semantic differential (SD) method and thermography measuring facial surface temperature have been used for emotion evaluation. The SD method provides a set of adjective pairs related to a product and evaluates changes in emotion from the use of the product. The range of facial surface analyzed is defined in the thermal image and temperature changes before and after the evaluation are analyzed. The evaluation items of home appliances include form, color, material, aesthetics, satisfaction, novelty, convenience, pleasantness, and excellence. Many existing emotion studies using skin temperature do not apply physiological and psychological methods. This study provides basic data to establish a skin temperature and emotion evaluation protocol by examining literature for skin temperature and evaluation of sensitivity.

Current methods to evaluate the performance of ROK military contingents to UN missions unnecessarily raises the issues of relevance, validity and reliability. Thus, this article aims to suggest how the result based evaluation (RBE) model which is widely adopted in the UN field missions as well as the international development community would be modified and applied to peace operation of the ROK contingent. As a result of the study, the model presents a framework that integrates the planning process and monitoring and evaluation with a logical framework, which entails a cycle of assessment of pre-deployment planning, monitoring and phased evaluation, and post-deployment evaluation. Secondly, according to measurement of RBE benchmarks to the present ROK's monitoring and evaluation system, factors in an evaluation unit and a logical framework approach are unmet or partly met to the benchmarks. In addition, ex-post impact evaluation has been rarely performed. Finally, the policy recommendations for resolution of the aforementioned challenges as well as a joint evaluation unit, participated by experts in a civilian, public, and a military domain are proposed.

Purpose - Consumers have memories of their past time that they have not experienced. So consumers want to experience the past time and get pleasure through historical contents such as movies or dramas. This is because the re-created the past time sets the identity of the consumers who live today, and in the process, it give consumers emotional comfort. Consumers do not remember and sympathize with all of their historical time. In general, consumers remember the time that their communities are proud of. As s result, historical content is seen as a hero, and through that, consumers can check their identity. Also consumers experience positive emotions such as self-esteem, gratitude and pride through identification with heroes. That is, through historical contents, consumers can identify themselves and replace the current negative emotions with positive ones. Therefore, this study presents narrative identity and historical nostalgia that can affect positive evaluation of historical contents and suggest the factors the can induce such effects. This study was conducted to explain what the consumption effect of historical content is from a marketing perspective and what constitutes a component of historical content as a factor driving this effect. Research design, data, and methodology - This study has developed a questionnaire with 8 Hypotheses. The Films ('Masquerade(2012)', 'Roaring Current(2014)', 'Assassination(2015)', 'The Age of Shadow(2016)') and dramas('Six Flying Dragon(2015-2016)', 'Mr. Sunshine(2018-2019)') were used as experimental contents. 268 college students participated in this empirical study, and structural equation model was used to verify hypotheses. Results - Frist, narrative identity affects positive evaluation of historical contents. Nostalgia affect positive evaluation of historical contents. and narrative identity affects positive response of historical nostalgia. Second, character act relevance, circumstance similarity, and character attractiveness have positive influence upon response of narrative identity. Lastly, empathy for story and vividness of representation have also positive influence upon response of historical nostalgia. Conclusion - This study contributes to the theoretical and managemental development of historical contents. This study shows that narrative identity and historical nostalgia are important for success of historical contents. In order for historical content to be successful, it must manage elements of character act relevance, circumstance similarity, and character attractiveness, empathy for story and vividness of representation.
