VOCs have been used as the most definitive resource to reflect customer feedback when developing products and services. However, due to the development of the Internet and the emergence of SNS, VOC is no longer the only channel that represents customer opinions. There are also a number of studies showing that many customers express complaints through channels other than VOCs. In this paper, we analyze the difference between the official VOC data and the data collected through the external channel, and suggest ways to reflect the various opinions of customers. To do this, this study uses keyword analysis that can identify differences according to frequency through social network, modular analysis to distinguish topics according to centrality and similarity, and emotional analysis to confirm word polarity (positive and negative). The results of this study show that the opinions of the customers were different depending on channels such as VOCs and external channels. Therefore, the collected data through VOC as well as external channels should be used in order to reflect the opinions of customers. In particular, this paper confirms that the results of one channel may vary depending on the channel characteristics even for the same channel. This confirms that collecting voc only on certain channels may differ from what real customers require. Therefore, data collected through VOCs as well as external channels must be used to reflect various customer feedback.

This pilot study examined programs for early childhood education and care in three Chinese cities. The samples for this study were one university-based kindergarten, one private kindergarten (rural area), and one public kindergarten (urban area). Six types of instruments were used to assess early childhood education and care services regarding quality matters. Most questions asked were open-ended; consequently, the interview answers by kindergarten directors or teachers (as well as observations made by the researcher) formed the basis for collecting the data. Quality components for each program were determined by a comparison method. The comparison allowed the researcher to understand the range of quality education and care available as well as the variability of existing kindergarten programs in China. The findings of the investigation revealed important information on; (a) demographic information (fees, class hours, total weeks of class, vacation, number of children and staff, class size, and teacher-child ratio) (b) teacher characteristics, (c) health practices, (d) safety practices, (e) work environment, (f) physical settings, (g) play materials, (h) parent involvement, (i) nutrition, (j) daily schedule. Implications within the Chinese context for quality practices and issues to further develop and strengthen early childhood education and care systems are discussed.

Purpose: The purpose of this study was to examine the effects on body temperature, shivering, and perceived thermal comfort of web-based evidence-based practice guideline for patients undergoing gastrectomy. Methods: Eighty patients scheduled for gastrectomy were recruited and assigned to the control or experimental group by sequential order. Before collecting data from the experimental group, a systematic educational program on evidence-based guidelines was provided to the nurses as well anesthesiologists. Data were analyzed using t-test and repeated measured ANOVA. Results: The experimental group showed higher body temperature from the induction of anesthesia until four hours after surgery compared to the control group. In addition, the levels of thermal comfort as well as satisfaction with thermal management were significantly higher in the experiment group. Conclusion: Use of evidence-based guidelines was effective in maintaining body temperature, lowering sensitivity to shivering, and promoting perceived thermal comfort. Therefore, adoption of evidence-based interventions in nursing practice is recommended.

There are emerging issues to update the educational environment for schools in terms of information and communication technology in order to provide customized programs to students as well as all participants relating to learning and teaching. The past year has been turbulent as the education facilities has changed and new procurement processes such as BTL have emerged. In this study, the feasibility analysis of ICT for the public educational environment is to analyse the current primary schools by means of collecting parent's opinion. In the web-site questionnaires, it was designed with 70 items such as teaching method, class organization, aptitude drill and educational community. As results, the statistical analysis is to propose the list of priority and orientation covering social agenda in the issue of ICT for education, the benefits schools can achieve by smart environment is to have the advanced learning services and solutions that represents parental engagement with identical local aims of interactive interface between their students and qualified teachers at a school. Both the national curriculum as well as the after-school program initiatives from the ministry of education, science and technology may reduce negative effects of private education so that the program has to be carefully developed for balanced education society revitalizing mutual communication within regional learning participants such as students, teachers and educational experts.

Directorate of Traffic of the Regional Police D.I. Yogyakarta as part of the Indonesian Republic Police (Polri) institution also experiences problems related to the performance of police members as well as the Polri institution in general. The problems which relate to the police performance are influenced by various factors such as low compensation and as a result low motivation in the work environment of Directorate of Traffic of the Regional Police D.I. Yogyakarta. Therefore, the objective of this study is to empirically test and prove the effect of the work environment and compensation on work motivation and police performance of Directorate of Traffic of the Regional Police D.I. Yogyakarta, Indonesia. This study used a survey method for collecting data. By using proportional stratified random sampling, 143 members of Directorate of Traffic of the Regional Police D.I. Yogyakarta were selected as the respondents. The results of this study indicate that work environment has a positive effect on work motivation, police performance as well as compensation on work motivation and police performance. In addition, work motivation has a positive effect on police performance. Thus, this study concludes that work motivation mediates the effect of work environment and compensation on police performance.

Because the estimation of the tensile strength is very important in any geotechnical project, many attempts have been made to determine. But the immediate determination of the tensile strength is usually difficult owing to well-shaped specimens, time-consuming, expensive and sometimes unreliable. In this study, engineering properties of several ultramafic rock samples were measured to assess the correlations between the Brazilian Tensile Strength (BTS) and degree of serpentinization, physical, dynamic and mechanical characteristics. For this purpose, a comprehensive laboratory testing program was conducted after collecting thirty-two peridotite and fifty-one serpentinite rock samples, taken from central Greece, in accordance with ASTM and ISRM standards. In addition, a representative number of them were subjected to petrographic studies and the obtained results were statistically described and analysed. Simple and multiple regression analyses were used to investigate the relationships between the Brazilian Tensile Strength and the other measured properties. Thus, empirical equations were developed and they showed that all of the properties are well correlated with Brazilian Tensile Strength. The curves with the $45^{\circ}$ line (y = x) were extracted for evaluating the validity degree of concluded empirical equations which approved approximately close relationships between Brazilian Tensile Strength and the measured properties.

AT(Aerial Triangulation) is the essential procedure for creating orthophoto and transforming coordinates on the photographs into the real world coordinates utilizing GCPs (Ground Control Point) which is obtained by field survey and the external orientation factors from GPS/INS as a reference coordinates. In this procedure, all of the GCPs can be collected from field survey using GPS and Total Station, or obtained from digital maps. Collecting GCPs by field survey is accurate than GCPs from digital maps; however, lots of manpower should be put into the collecting procedure, and time and cost as well. On the other hand, in the case of obtaining GCPs from digital maps, it is very difficult to secure the required accuracy because almost things at each stage in the collecting procedure should rely on the subjective judgement of the performer. In this study, the results from three methods have been compared for the accuracy assessment in order to know if the results of each case is within the allowance error: for the perceivable objects such as road boarder, speed bumps, constructions etc., 1) GCPs selection utilizing the unique LiDAR intensity value reflected from such objects, 2) using LiDAR DSM and 3) GCPs from field survey. And also, AT and error analysis have been carried out w ith GCPs obtained by each case.

This paper proposes an on-line voltage management and control solution for a distribution system which can improve the efficiency and accuracy of existing off-line work by collecting customer voltage on-line as well as the voltage compensation capability of the existing ULTC (Under Load Tap Changer) operation and control strategy by controlling the ULTC tap based on pattern clustering and recognition. The proposed solution consists of an ADVMD (Advanced Digital Voltage Management Device), a VMS (Voltage Management Solution) and an OLDUC (On-Line Digital ULTC Controller). An on-line voltage management emulator based on multi-thread programming and the shared memory method is developed to emulate on-line voltage management and digital ULTC control methodology based on the on-line collection of the customer's voltage. In addition, using this emulator, the effectiveness of the proposed pattern clustering and recognition based ULTC control strategy is proven for the worst voltage environments for three days.
