In this paper, we propose an energy monitoring and management service based on wireless sensors and a home gateway for homes and buildings. Homes and buildings have a significant energy saving potential compared with other sectors. Sensing, monitoring, and managing of the information on the energy consumption are required for an efficient energy saving service. The proposed system is composed of two main components, wireless sensor and an intelligent home gateway. Wireless sensors have the ZigBee communication interface for communication, and the intelligent home gateway is an energy portal. We expect that energy saving could be achieved with this system. As a further work, we will analyze the practical impact of the proposed service.

To improve the practical application of the thermal expansion of closed long pipeline exposing to external heating sources such as solar energy, safety engineering and system optimization for relief valve in the closed piping system are suggested through theoretical approach, correlation in view of temperature and pressure increase caused by external solar energy in the closed piping system. The profile for thermal relief valve including relieving capacity, influx heat energy, sizing criteria, set pressure, selection against back pressure is also presented. It is noted that following topic on solar relief valve should be applied to engineering, installation and commissioning.

The research develops the calculation steps of Z sigma level, process capability index(PCI) and process performance index(PPI) applicable to the discrete process in the service industry. The paper presents three following topics used related process indexes according to the precision and accuray in the continuous process. The contents include diverse process indexs for nonconformities by SPC attribute control charts and bias coefficient. The same technique of the nonconformites is also used in the nonconforming units. The practical examples are provided to help easier understanding for users.

The User Interface (UI) in the company is more important than ever. But the application of UI for the industry use is restricted by various constraints such as delivery, technical limitation, etc. User Interface designers in the company have thought how to set up the UI organization, how to define identity and goal, how to communicate with other teams, what is the best UI process, and many other issues. In this paper, the author discuss the practical issues arisen when User Interface organization is formed and managed based on the mobile phone manufacture's perspective. The pros and cons of location of UI organization, advanced UI organization, UI member formation, UI role, UI output, UI evaluation, and understanding of UI in the society and company are discussed. This discussion will help UI designers in industry to set up and manage UI organization.

Recently, many enterprises are interest in implementing Radio Frequency IDentification (RFID). However, they have some difficulty in implementing RFID because of incompleteness of RFID technology and uncertainty of Return on Investment (ROI). Even though usefulness of RFID are recognized, many enterprises are just interested in planning of RFID rather than implementation of RFID. Among successful factors of RFID implementation, Information Technology (IT) capability is the most important one. If enterprises have systematic IT capability, it would make positive attitude to implement RFID. In addition, it will provide trust about RFID and promote adoption of RFID implementation. This study, therefore, empirically analyzed the relationships of trust, attitude, IT capability, and intention to RFID adoption using Partial Least Squares (PLS) approach. The result show useful guidelines and practical implication in implementing RFID.

Based on the practical process engineering design and commissioning and startup operation experiences focused on chemical process safety, the comprehensive review of engineering design and installation of the thermal relief valve with its surrounding facility in a chemical plant piping system is provided to enhance the better understanding of the piping system of characteristics of thermal relief valve which is comprised of the theoretical approach, correlation in terms of temperature and pressure increase caused by external heat supply in a piping system, consideration of thermal relief valve engineering design, pressure relieving system of serial thermal relief valves and exception of their installation. It is earnestly suggested that following topic should be implemented during thermal relief valve engineering design, installation and normal operation as well.

This study analyzes the transition of the Family-Friendly Index from 2007 to 2012. This index was developed using a questionnaire survey that is distributed to listed companies and public institutions every year by the Ministry of Gender Equality & Family(MOGEF) and the Family-Friendly Support Center. The Family-Friendly Index contains an introduction to and the practical use of family-friendly regulations and programs, such as flexible working systems, parental leave, family leave, EAP, and family-friendly culture. The number of companies involved in the Family-Friendly Index is increasing every year, and has increased from 41.7 in 2007 to 58.9 in 2012. In particular, family-friendly companies testimonialized by the MOGEF are using more family-friendly programs than other company.

The purpose of this study is to examine the effect of preparation for old age on the life satisfaction, and the mediating effect of productive activities on the relationship between preparation for old and life satisfaction among the old age in Korea. The subject for this study is 226 older adults who participated in the work fare program of community welfare centers. The collected data were analyzed with SPSS WIN(ver.18.0) program, and frequency analysis, descriptive analysis, multiple regression, and Sobel test were utilized. The result revealed that productive activities has a partial mediating effect between preparation for old Age and life satisfaction. Based on these findings, the theoretical and practical implications were discussed.

The importance-performance analysis (IPA) is a widely used analytical technique that produces a priority of managerial attention for the customer satisfaction. This study attempted to compare various different approaches of IPA such as direct and indirect measurement of importance, and traditional four quadrants grid model and diagonal grid model of IPA. Data on 17 inpatient service quality attributes were collected from 234 inpatients of a general hospital. Eight IPA grids were produced to compare the result of each model. Based on the study results the strength and weakness of each model were discussed, and a set of recommendations for practical application of the IPA in hospital settings was suggested.

Purpose : This study is to analyze the inpatients's experience of medical services provided by hospital including medications, treatments, and environment. Based on the results of surveys conducted as part of the inpatient experience evaluation in A hospital in Goyang, Gyeonggi province. Methodology : A sample of 300 adults aged 19 years or older who had more than one day of hospitalization was selected. The questionnaire was conducted from April 3rd to June 21st, 2017 by telephone. Findings : It is found that recommendation intention influenced by medical services, hospital environment, medication treatment process. but it turns out that there is no moderate effects of health condition between patient's experience and recommendation. Practical Implication : In order to improve the inpatient experience, there should be a way to improve experience in providing patient-centered services in the hospital s environment, medication and treatment.
