Purpose : To provide a convenient framework for PNF practice, we reviewed the relationship between ICF framework and PNF framework. Methods : We reviewed literatures related with ICF and PNF. Results : ICF model is useful tool for physical therapist who is working in PNF to identify the interactions the components of individual's health, especially the relationship between functioning and disability. A framework for PNF is philosophy which included the concept, functional approach. It is essential to identify primary activity limitation and causal impairment in PNF field and evaluate the their relationship. The ICF model can be used to classify the examination information. Next step is to prioritize the activity limitation and then evaluate the interrelationships among each components of the ICF framework. Conclusions : ICF model guides physical therapist in PNF practice to identify patient problems and evaluate the interrelationship of components of their health. This model is logical framework to directs functional approach as PNF philosophy to be approached the goal.

This paper deals with the application of PRICE model in estimating the proper acquisition cost for weapon budgeting phase. The PRICE(Parametric Review of Information for Costing and Evaluation) Hardware model is a computerized method for deriving cost estimates of electronic and mechanical hardware assemblies and systems. The model can be used in obtaining not only initial cost estimates in conceptual phase, but also detailed cost estimates in budgeting phase depending on available historical and empirical data. We analyzed first step cost estimate parameters and derived cost equations using PRICe output dta. Using weight and complexity, We can find cost variation. Sensitivity analysis shows that cost increases exponentially as complexity increases exponentially as complexity increases. We estimated KAAV\`s (Korea Amphibious Assault Vehicle) production cost using the PRICE model and compare with engineering cost estimates which is based on actual production data submitted by the production company. The result shows that tow estimates are close within $\pm2%$ differences.

The Parameters of the storage function model (SFM) are taken as constants, while they have different values during every rainfall period and the duration of the runoff. Therefore, the results of the SFM generally show remarkably large errors. In this study, the modified storage function model (MSFM), in which the time variant parameters are introduced, is proposed to improve the SFM which is a conceptual rainfall-runoff model. The fuzzy reasoning method is applied as a real-time control one of the time variant parameters of the proposed model. The applicability of the MSFM was examined in the Bochung river, at a tributary of the Geum River, Korea. The pattern of the predicted runoff hydrograph and the peak discharge by the MSFM with fuzzy control are very similar to the measured values, compared with the results produced by the SFM.

Many researchers and practitioners have paid much attention to identifying some critical factors for the successful implementation of the TPS, EDP and MIS. However, not much effort have been focused on the implementation issues of DSS which is different from TPS or MIS in terms of the scope of the system, evaluation criteria, decision types served, and level of users. Because of these differences, implemention of DSS should be planned and approached from different aspects of TPS, EDP and MIS. A conceptual model includes four characteristics as independent variables and three dependent variables such as system usage, user's satisfaction, and user's attitude. This paper is to empirically prove the usefulness of the model and to identify a model for the successful implementation of DSS in Korea. It will provide a better understanding of the variables associated with the successful DSS implementation.

Recently, conceptual information model is changing fast, and these changes are coming about as a result of individual tendency, social cultural, new circumstances and societal shifts within big data environment. Despite the data is growing more and more, now is the time to commit ourselves to the development of renewable, invaluable information of social/live commerce. Because we have problems with various insoluble data, we propose about deep learning prediction model-based object classification in social commerce of big data environment. Accordingly, it is an increased need of social commerce platform capable of handling high volumes of multiple items by users. Consequently, responding to rapid changes in users is a very significant by deep learning. Namely, promptly meet the needs of the times, and a widespread growth in big data environment with the goal of realizing in this paper.

The purpose of this research is to develop a conceptual model that establishes a new approach for functional area cost estimating in the schematic design phase. A cost estimating model should consider not only the estimate accuracy, but also the flexibility to the design alternatives and user-oriented serviceability. Therefore, this research uses the method that classifies various facilities of a building according to its functions by analyzing historical data. After setting the functional area as cost parameter, a formula which can estimate functional area cost is derived from statistical analysis. Finally, to validate the proposed conceptual model, it is applied to historical data of a military barrack project. It enables customized space planning reflecting client's needs and compares the cost of various design alternatives as well as improves estimate accuracy.

A large amount of fine dust is generated during the process of pavement cutting. Consequently, reducing the amount of fine dust generated during pavement cutting is crucial for the overall management of fine dust. Based on this premise, in this study, a conceptual model is proposed for a device that can be employed for recovering scattered dust generated at the site of pavement cutting. The economic feasibility associated with the incorporation of the proposed model was analyzed. Results obtained from the economic feasibility analysis of the proposed conceptual model indicate that the benefit ratio is 2.96, which is significantly higher than 1. The rate of return is found to be 62.78%, which significantly exceeds the minimum expected rate of return (i.e., 10%), as established on the basis of interviews conducted with companies that implement pavement cutting. Furthermore, the break-even point is found to be at approximately 21.6 months. Hence, the proposed pavement cutter, which features dust suction and a low noise level, is economically feasible.

The purpose of this study was to explore the concepts of health among people with mobility disabilities in order to develop a new holistic model of health and to identify implications for social work practice. A qualitative study based on face-to-face interviews with people with mobility disabilities was conducted. Nine consumers and nine social workers with mobility disabilities participated in the study. Social constructionism, heuristic paradigm, empowerment paradigm, and strength perspectives were used to form conceptual foundations to guide the study. Study participants' holistic descriptions of the concept of health encompassed five domains: biological/physical, mental/emotional, financial, relationships with others, and spiritual. Participants described health as harmony among these five domains. Harmony indicates that all five domains contribute to the concept of health, and that each domain is related to the others. Participants also viewed disability and health as an interconnected whole, not separate concept. The conceptual model developed in this study expands on the existing concepts of health by considering multiple factors at the personal and environmental levels, as well as interactions among the factors and between the levels. The personal level has five domains: biological/physical, mental/emotional, spiritual, financial, and relationships with others. The environmental level has also five domains: relationship with others, financial, social programs, social attitudes toward peoplewith disabilities, and physical environment. All factors under the personal and environmental levels also affect each other. The holistic concept of health for people with disabilities is not solely a part of the person, but rather is a function of the interaction between the person and their environment. The study demonstrated that people with disabilities have strength and resiliency, and health is an attainable goal for them, particularly when environmental and cultural barriers are addressed. The focus of social work practice should be the removal of those barriers encountered by their consumers with disabilities, as well as, the enhancement of internal factors that facilitate well-being.

In this study, the variability of the Horton index which is ratio of vaporization and wetting water is investigated using a conceptual soil water balance model. From the proposed model, the steady-state soil water probabilistic density function is derived through meteorological and watershed characteristics and then the sensitivity of Horton index to the precipitation occurrence rate and the mean of wet day precipitation is examined. As a result, the inter-annual variability of the Horton index is lower than that of precipitation and they showed the strong negative correlation. It is also shown that although precipitation is not varied, the Horton index can be varied due to the fluctuation of the precipitation occurrence rate and the mean of wet day precipitation. In addition, it is presented that there is a non-linear relationship which has a critical point switching proportional or inverse relationship between the Horton index and two main characteristics of precipitation process.

Business analytics is a management tool for achieving significant business performance improvements. Many organizations fail to or only partially achieve their business objectives and goals from business analytics. Business analytics adoption is a multi-stage complex activity consisting of evaluation, adoption, and assimilation stages. Several research papers have been published in the field of business analytics, but the research on multi-stage BA adoption is fewer in number. This study contributes to the scant literature on the multi-stage adoption model by identifying the critical themes for evaluation, adoption, and assimilation stages of business analytics. This study uses the thematic content analysis of peer-reviewed published academic papers as a research technique to explore the key themes of business analytics adoption. This study links the critical themes with the popular theoretical foundations: Resource-Based View (RBV), Dynamic Capabilities, Diffusion of Innovations, and Technology-Organizational-Environmental (TOE) framework. The study identifies twelve major factors categorized into three key themes: organizational characteristics, innovation characteristics, and environmental characteristics. The main organizational factors are top management support, organization data environment, centralized analytics structure, perceived cost, employee skills, and data-based decision making culture. The major innovation characteristics are perceived benefits, complexity, and compatibility, and information technology assets. The environmental factors influencing BA adoption stages are competition and industry pressure. A conceptual framework for the multi-stage BA adoption model is proposed in this study. The findings of this study can assist the practicing managers in developing a stage-wise operational strategy for business analytics adoption. Future research can also attempt to validate the conceptual model proposed in this study.
