This study intended to investigate factors shaping the styles for comsumers to express their dissatisfaction after comsuming goods(cloth and household appliance) and services(public and health) In particular this study examined what kinds of characteristics were crucial to distinguish three styles of consumers' and public complaints. The characteristics of consumer to be considered in this study included consumer knowledge consumer attitude consumer and several socio-economic characteristics. The sample used in this study were consumers whose age was grater than 20 years old living near Seoul in 1996. Discriminant analysis was conducted to investigate what factors discriminate the style of complaint. This study found that several consumer characteristics were sigificant in explaining different styles for consumers to response their dissatisfactions. The effects of consumer characteristics were more significant in explaining the complaining styles derived from public and health services rather than goods. Overall consumer attitude consumer knowledge and the degree of satisfaction of services were discriminant variables in explaining the styles of consumer complaint. Both consumer knowledge and budgeting skill were significant in explaining complaint styles to response dissatisfaction derived from consuming clothing while both consumer education and time constraint were significant in shaping the kinds of complaining styles derived from consuming household appliances.

The Web Services Choreography Description Language (WS-CDL) is an XML-based language that describes peer-to-peer collaborations of parties by defining, from a global viewpoint, their common and complementary observable behavior; where ordered message exchanges result in accomplishing a common business goal. In this paper, we survey and analysis the functionality of the WS-CDL, and propose new language, which enhance the WS-CDL for the conversation the message between entities

Recently main Bioinformatics databases(DDBJ, ENSEMBL, KEGG, etc.) provide analysis tools and data using web services for the convenience of bioinformaticians. Thus, defining SOAP server objects and their methods are very important to provide services for web services. We define SOAP server objects for interaction databases such as BIND, MINT and DIP.

This study aims at the fundamental factors needed to make the policy for internet reference service of public records were presented, considering the methods for improvement of internet reference service of national assembly records. For this purpose, reference service theory of recorded informations and examples of foreign congress reference services were analyzed. From the result of analysis, three tasks were proposed as an improvement plan for internet reference services of national assembly records: establishment of access policy, improvement of reference service programs, and activation of communication with users.

The user increases around the WiBro and in which the mobile broad band service is the wireless internet base technology HSDPA, that is the cellular phone foundation technique, and moreover the issue about the user effective quality guarantee emerges but the quality control of the wireless network is the incomplete actual condition. Therefore, the reliability verification according to the development of the system for the performance measure for the continued wireless data service and it and evaluation are needed for the quality control. In this paper, the wireless data service quality measurement system was implemented with the design. The same test environment as the existing network performance measurement program was built for the reliability verification of the embodied device for measuring quality and evaluation and the cost performance was performed. It could confirm that design and embodied wireless data service quality measurement system operated accurately in this paper through the quality measure result value analysis.

Under awareness of the importance of interaction between local research agencies and farmers in developing local agriculture, this study attempts to analyse the level of interaction in extension services of Experiment Station. The data were collected through the interview with researchers in five Experiment Stations and farmers who have made contact with the researchers. The results of the analysis are as follow: (1) The Experiment Stations are currently providing extension services though they are originally research-oriented agencies. The extension methods of Experiment Stations are similar with those of extension agencies. (2) The more systematic the characteristic of extension service type is, the higher level of interaction is generated with several exceptions which should not be ignored. This study accentuates the efforts to improve the level of interaction as well as to construct a system as a linked set of actors.

ISDN, the beginning of broadband and multimedia service, is a digital network that provides integrated end-to-end digital telecommunication services for transmissions of different kinds of information, from voice and facsimiles to data and images. In Japan, Britain and U. S there has been shown the demand of ISDN is considerable and ISDN technology is becoming quite stable. Furthermore,their ISDN service experience helps them to set up and carry out the marketing strategies for Internet access services such as ADSL, Cable Modem and WLL, etc. This paper examines and compares services, charge and discount scheme of ISDN across 14 telecommunication carriers. It can be utilize as a reference for diffusing ISDN as well as developing Internet access services and marketing strategies.

In traditional organic rice culture practices, control of weeds is a big problem. This study was conducted to increase the rice production. Results showed that Plant height, SPAD, root length and weight were higher in pot raised seedling than broadcasting method except number of panicles. High plant density caused reduction in plant height, number of culm and chlorophyll content of the rice. No lodging was observed in both methods. Thickness of third internode and culm length was more in pot raised seedlings at both sites. When organic material was used rice yield increased by 3.81%. Higher rice production (10%) was recorded in the fields planted with pot raised seedlings. From the above study it could be conclude that the pot raised seedlings perform better than the seedlings raised by broadcasting methods.

A lot of researchers have been interested in the factors influencing the use of mobile phone services. Most of the previous studies, however, verified only the research models developed by the authors. They did not consider which model agrees better with the real situation. This study presents six alternative models based on various previous studies, and compares the data fitness of the models. A Web survey of mobile phone users collected 2,217 cases. Statistical analyses, using SEM (Structural Equation Modeling), show that the fitness of the simplest alternative model is better than that of any other model. The simplest model has no causal relationship among exogenous factors, and proposes that all of exogenous factors have direct impacts on the customer satisfaction. In addition, the analyses say that corporate and brand image and additional service are more important than the other exogenous factors such as communication quality.

This research shows how the perception of digital shadow work varies depending on the user's period of use of digital services in applications, which are key areas of digital services. The purpose of this research is to investigate how the digital shadow work type changes over time. This research adopted a qualitative research method for location-based service "help application" users and examined the change in perception from the app service acceptance stage to the app service continuous use stage with two-times interviews of ten users by a longitudinal research design. This study conducted a longitudinal analysis focusing on how digital shadow work occurs in the application subscription process, exploring phenomenologically how the type changes throughout the process over time.
