In this paper, we analyze process of implementing and successful enabler of Postal Logistics Integrated Information Systems(PostNet) through a case study on Korea Post. PostNet was integrated by considering contingently organizational integration (organizational structure redesign), strategical integration (business process reengineering), and technical integration(data integration, application integration, and integrated platform implementation). And also integration was implemented for supporting three aspects. PostNet has implication for advanced integration with business mission and operational efficiency by comparing integration with physical level and hardware level. Korea Post has the biggest logistics network, organization, and service in logistics industry area. The results of this paper will suggest theoretical framework for the future information system integration, and will be utilized as a practical guideline for the information system integration.

Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

Recently, Mergers and Acquisitions (M&A) have become increasingly popular in the last few decades, and overseas' M&A are particularly increasing to sharpen corporate competitiveness on a global scale. Previous studies showed that one of the main reasons attributes to failures of mergers was the lack of attention to merging information systems. In recent years, both academy and industry have more focused on Post-Merger Integration (PMI) and the integration of information systems (IS) between two companies is one of the critical success factors of corporate. This paper focused on Post-Merger IT (Information Technology) Integration Methodology of Cross-Border M&A. We followed a single-site qualitative case study method in order to investigate the type of phenomenon in M&A's natural setting. Moreover, we examined a typical energy and power company case in order-based industry, so that other industry players may have different results to determine post-merger IT integration method and scope.

This paper describes how to storing and querying trajectory information on PostgreSQL/PostGIS. Recently as technology of mobile devices is advancing, many researches for location-based services and moving object's trajectory have been studied. Trajectory is the set of information of the location by the time, and is one of the most im portant information for location-based services. Traditional spatial database systems do not support trajectory data types and functions. In this paper, we propose a trajectory data type and query functions for moving objects on PostgreSQL/PostGIS.

"디지털 가전용 Post-PC"라는 새로운 유형의 정보 단말기를 Post-PC 요소기술(CPU, OS, Middleware)들을 바탕으로 구현하고 그에 대해 설명한다. 개발된 플랫폼은 XScale 기반의 하드웨어에 운영체제는 임베디드 리눅스를 사용하고 윈도우 시스템은 임베디드 QT를 사용하여 설계되었다. 기존에 나와있는 다양한 Post-PC 제품들과 비교하여 차이점 및 장 단점에 대해 논하고 차기 개발될 플랫폼이 경쟁력을 갖출 수 있도록 새로운 방향을 제시한다. Post-PC 표준 개발 플랫폼으로의 활용과 임베디드 응용 소프트웨어의 개발 플랫폼으로의 활용, 기타 응용 제품 개발에 활용될 것으로 기대된다.

Recently, open sources for geo-spatial information processing and analysis are being developed, and they are widely adopted for the various application development projects. Open sources in the geo-spatial communities consist in several levels or types: viewer, API-level, engine sources of SDK-level, or toolkits. Among them, spatial database engine of PostgreSQL-PostGIS is used in this study for the portable multi-geospatial information processing toolkit. This work can be extended to target-based applications with domain-specific spatial queries and analyses. Design and implementation are based on C Language Interface (LIBPQ) to PostGIS and OGC library on PostgreSQL database. Conclusively, PostGIS according to this approach is an important alternative to develop most applications dealing with multi-geospatial information due to its availability, extensibility, scalability, and stability.

In this study an evaluation method is proposed, with the strong relationship between the ante and post audit works evaluation. The ante evaluation does in general and systematic ways, with past audit results and proposals. The criteria-based evaluation is used for the audit activities and outputs. The critical success factors for the projects applies to the activities evaluation and product evaluation framework to the output. The ante and post evaluation have the cross evaluation items to be the whole and continuous one. Eighteen common evaluation items are derived, with their own evaluation elements in detail, which have only differences of the actually done and expectations between the ante and post. The proposed evaluation makes the ante and post one to be related with each other in a systematic and objective ways, to enhance the reliability of audit results and effectiveness of the audit.

The purpose of this study is to investigate the evaluation perspectives of IT business value and empirically analyze the differences of evaluation perspectives between ex ante evaluation and post implementation evaluation, and among various information system types. 4 evaluation perspectives which have been used in the previous studies and in the field of industry practices are financial, customer, internal process, and growth, which are based on the BSC model. Data of 98 information systems have been collected from 89 companies including manufacturers, banks, insurances, and stock trading companies. As results of multi-way MANOVA test, 3 out of 8 hypothesis have been accepted statistically. While the order of importance of 4 perspectives in ex ante evaluation is customer, financial, internal process, and growth, the order of post implementation evaluation appears to be much different : that is, internal process, customer, financial, and growth. These findings provide insights for both IT practitioners and researchers.

Purpose: The purpose of this study was to examine the effects of interactive pictorial education on community dwelling older Korean adults' self-efficacy and knowledge for safe medication. Methods: A quasi-experimental, three-group pre- and post-intervention design was used in this study. The interactive pictorial education was designed to suit the learning patterns and psychomotor skills of older adults. The education content, dealing with safe medication, was delivered over three sessions. A total of 136 older adults from local senior centers were assigned to one of the three groups: a) interactive pictorial education plus information booklet (experimental); b) education only with information booklet (conventional); or c) no intervention (control). Results: Participants receiving interactive pictorial education had significantly higher self-efficacy (F=24.32, p<.001) and knowledge (F=24.26, p<.001) scores than the information booklet or control group at post intervention. Post-hoc analyses indicated that both the interactive pictorial and the information booklet groups had significantly higher self-efficacy and knowledge scores than the control group at the post-test point (p<.05). Furthermore, the interactive pictorial group had higher self-efficacy and knowledge scores than the information booklet group at the post-test point (p<.05). Conclusion: These results suggest that the interactive pictorial education is an innovative approach that provides a means for older adults to learn appropriate medication use to improve their own health. It empowers older adults with different literacy levels to enhance their self-efficacy and knowledge for the safe use of medication.
