The Internet has produced a great variety of VOC data. However, they are hardly helpful for CRM because they are not integrated with VOC data of the related businesses yet. This paper has set up a system for the said VOC data to actually become helpful for CRM The system has two aspects. From the aspect of products, the customers' needs for products will be analyzed to produce what they actually want. From the aspect of customers, on the other hand, decent relationships with them shall be maintained constantly by thoroughly analyzing all the related data. The analyses on both of these aspects have the advantage of maximizing customer satisfaction by active CRM that makes us recognize what customers prefer, or complain of in advance and then provide them with tailor-made service.

Background: The aim of this study was to determine factors affecting sleep quality of 100 patients with advanced stage lung cancer. Methods and Results: it was a descriptive study. A variety of assessment tools were used to provide sleep scores to examine the relation between adverse effects caused by the treatment (nausea, vomiting, fatigue) and sleep quality. As a result, no statistically significant relation between coughing and respiratory problems of patients, or existing depression, and average sleep quality score was found (KW:0.872, p=0.646, KW: 3.174, p=0.205, u: 441.000 p=0.916). It was revealed that nausea and loss of appetite experienced also did not affect the sleep quality score (p>0.05), whereas problems such as vomiting and fatigue did exert effects (p<0.01). Conclusions: Patients with advanced stage lung cancer suffer from sleep problems and cancer related symptoms also affect their sleep quality negatively. Nurses should plan interventions that can control symptoms such as pain, vomiting and fatigue, which affect the sleep of patients.

Twitter is a microblogging service that allows users to post short messages on a variety of topics in real-time. In this work, we analyze Twitter messages posted during the 2012 elections and find those implications. This study uses Twitter messages related to the 2012 South Korean presidential campaign. The three main candidates are represented by the abbreviations A, M, and P. According to the statistical analysis, the number of tweets and re-tweets for candidate P was relatively stable over the entire campaign period. Candidate P had the highest percentage of terms related to elections pledges, and candidates A and M were judged to be a little bit poorer with respect to campaign promises. The positive terms ratio for candidate P was higher than those for the other two candidates. The negative terms ratio in the Twitter messages of P was considerably smaller than those of candidates A and M. After considering all these results, it is suggested cautiously that Twitter messages posted during an election campaign could be correlated with the outcome of the election.

This paper proposes an image processing algorithm for detecting obstacles on road using DLI(disparity of lane-related information) that is generated by stereo images acquired from dual cameras mounted on a moving vehicle. The DLI is a disparity that is acquired using a single lane information from road lane detection. For the purpose to reduce processing time, we use small block of edge-histogram based blocking logic. This algorithm detects moving objects such as preceding vehicles and obstacles. The proposed algorithm has been implemented in a personal computer with the road image data of a typical highway. We successfully performed experiments under a wide variety of road conditions without changing parameter values or adding human intervention. Experimental results also showed that the proposed DLI is quite successful.

This study explored how intrinsic and extrinsic motivation relates to achieving creativity at project work. We were interested in differences in how motivational factors relate to creativity. Using data from the 98 engineers and researchers employed by a variety of companies, principal components factor analysis with marimax rotation was performed on the data. We examined effects of the moderate variables the intrinsic and extrinsic motivation and creativity relationship. The results indicate of positive mental involvement, the time and the resource constraints relates positively to creativity in organizations and that the relationship is a simple linear one. These outcomes are significantly related to intrinsic motivation and the creativity. In additions, extrinsic motivation is related to less the creativity. Our survey findings are also consistent with other sources of knowledge on the topic. Our results suggest that there are two different role: mental involvement, time and resources constraints, both of which predict creativity, and external control and extrinsic motivations reduce to creativity.

Nowadays social environment is rapidly changed toward globalization and information age, and which demands the new paradigm for active utilization of information system in many fields. The increasing availability and ease of accessibility of the internet using world wide web have resulted in an enormous increase in the amount of nutrition information in countries with advanced information technology. However, Domestic web services in nutrition field are neither diverse nor professional currently. Nutrition experts need to take advantage of the resources offered though the web and take an active role in providing reliable and accurate information and preventing the growth of nutrition misinformation though web. Nutrition web sites on a variety of subjects should be developed depending upon the objectivity of nutrition resources and the target clients. Nutrition-related organizations are responsible for monitoring nutrition web information and encouraging open discussion and evaluation of hot issues among experts, and between experts and clients through the internet.

In this paper, we propose a keyword query processing technique based on semantic relationships for OWL data. The proposed keyword query processing technique can improve user's search satisfaction by performing two types of associative search. The first associative search uses information inferred by the relationships between classes or properties during keyword query processing. And it supports to search all information resources that are either directly or indirectly related with query keywords by semantic relationships between information resources. The second associative search returns not only information resources related with query keywords but also values of properties of them. We design a storage schema and index structures to support the proposed technique. And we propose evaluation functions to rank retrieved information resources according to three criteria. Finally, we evaluate the validity and accuracy of the proposed technique through experiments. The proposed technique can be utilized in a variety of fields, such as paper retrieval and multimedia retrieval.

In the construction industry, construction process includes a variety of design stages with cooperation and regulation by many related disciplines. In addition, the construction market is growing and becoming more complex. With this characteristic, design information has become more and more complicated and difficult to manage by the simple and traditional data management methodology. In the practical field, although CAD has been widely available for the last ten years, related disciplines have not shared digital information efficiently. This paper suggests a construction CAD data exchange model that has been developed through investigation and analysis of Korean construction CAD practices and foreign CAD standards. Moreover, this paper investigates a CAD data exchange model using STEP to improve information availability and overcome the limit of CAD systems.

A retrograde tracer, WGA-apo-HRP-gold, was injected into midline thalamic nuclei and subsequently orexin-A immunostaining was performed on the tuberal region of the hypothalamus in order to investigate orexinergic projections to the midline thalamus. Injection site was targeted within one specific region, i.e., paraventricular, centromedian, rhomboid, reuniens, or intermediodorsal nucleus, but it proved to be either one or a combination of these thalamic nuclei. The distribution of WG/orexin-double-labeled neurons exhibited a general pattern in that the majority of labeled cells were observed within the ventral portion of the lateral hypothalamus as well as the perifornical nucleus (PeF). A small number of double-labeled cells were also observed at the dorsomedial nucleus, the area dorsal to the PeF, dorsal portion of the lateral hypothalamus, and the posterior hypothalamus. These orexin-immunoreactive neurons might have wake-related influences over a variety of functions related with midline thalamic nuclei, which include autonomic control, associative cortical functions, and limbic regulation.

The current regulations and laws related to landscaping facilities within apartment estates stipulate the proportion of the estate lot allocated to green area and landscaping. These regulations define the criteria for landscaping, the density of trees and other related matters. In fact. the selection and locations of trees are determined by the builder. The builder first decides the location of the building and then allocates the residual land to landscaping. So landscaping within apartment complexes is often unmet to residents' need and ecological growth and function of trees and plants. This study was designed to examine the variety of trees and their location as an aspect of their function within each area of the YS and DK apartment complexes. As the results, the difference in the two estates is striking in aspects of quantity and quality. Even though the regulations for landscaping within apartment estate is met. the real landscaping is often unmet to residents and general people.
