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.

Based on the premise that perspectives or the frame of cognition may affect the ways that family practitioners support or intervene in families, this study aimed to investigate the perspectives of Certified Healthy Family Specialists (CHFS) on family practice in the Healthy Family Support Centers. A total of 9 CHFSs gave information about their beliefs and perspectives on family practice in in-depth interview. Additionally, 5 CHFS participated in focus group interview and gave information about their values, beliefs, and perspectives on family practice. Through qualitative analyses, four perspectives were found to be explicitly or implicitly carried by CHFSs: System theory perspective, Strengths perspective, Family cognition perspective, and Public intervention perspective. These four perspectives are currently leading themes of family research and are prospected to prevail in family support and intervention practices in the Healthy Family Support Centers in South Korea. Based on the results of qualitative analyses, directions and range of influence in perspectives on family practice perceived by CFHSs were discussed. In this study, the subject of Healthy Family Project, the CHFSs' aims, and emphasis on family practice were dealt with, and developmental direction establishment related to the Healthy Family Support Centers and CFHSs in the dimension of practice and policy in the future were implied.

In developing the ubiquitous computing technology based services (ubiquitous services), evaluating how much value of those services is created or added is very crucial. The efforts to evaluate the ubiquitous services have been progressed in two perspectives - technical perspective and behavioral perspective. Despite its importance, however, the methodologies which integrate both perspectives have been still very rare. Hence, this paper aims perspectives have been still very rare. Hence, this paper aims to propose an integrated ubiquitous service valuation methodology based on the multi-layered approach including technical and behavioral perspectives. To do so, we conducted a case study with currently existing location based service (LBS) such as navigation systems by conducting focus group interview (FGI) and field survey.

This study was designed to find the characteristics and patterns in subjectivity of the perspectives on the coping strategies about practical stress in nursing student. Q-methodology was used as a research design and the research procedures were as follows. Q-sampling has been derived from the literature review and a questionnaire. Its credibility and validity were also tested by nursing professors. Total of 34 statements were selected. P-sampling has been drawn and 51 samples were selected. Based on 9 point scale, the selected respondents rated their operant definition on the perspectives on the coping strategies about practical stress in nursing student. The results of above procedures were analyzed by PCQ program. The perspectives on the coping strategies about practical stress in nursing student were analyzed based on the typical array, extreme comments, and the demographic information of study subjects. The results revealed that there were three types of the perspectives on the coping strategies about practical stress in nursing student. The three types were named as follows; 1) The first type, agree of positive change by oneself perspectives, was consisted of 18 subjects. They thought that they did their best positive change for the most effective coping strategies about practical stress. 2) The second type, agree of social support perspectives, was consisted of 13 subjects. They thought that they asked for an other person's help for the most effective coping strategies about practical stress. 3) The third type, agree of looking on avoidance perspectives, was consisted of 5 subjects. They thought that they looked on or avoided problems for the most effective coping strategies about practical stress. As a result, this study discovered three types of the degree of the perspectives on the coping strategies about practical stress in nursing student. By identifying the nature of each of three types, this study can be useful to develop efficient coping strategies about practical stress in nursing student.

In multi-view subspace clustering, how to integrate the complementary information between perspectives to construct a unified representation is a critical problem. In the existing works, the unified representation is usually constructed in the original data space. However, when the data representation in each view is very diverse, the unified representation derived directly in the original data domain may lead to a huge information loss. To address this issue, different to the existing works, inspired by the latest revelation that the data across all perspectives have a very similar or close spectral block structure, we try to construct the unified representation in the spectral embedding domain. In this way, the complementary information across all perspectives can be fused into a unified representation with little information loss, since the spectral block structure from all views shares high consistency. In addition, to capture the global structure of data on each view with high accuracy and robustness both, we propose a novel low-rank approximation via the tight lower bound on the rank function. Finally, experimental results prove that, the proposed method has the effectiveness and robustness at the same time, compared with the state-of-art approaches.

Recently, local governments have started projects of implementing Geographic Information Systems (GIS) as an infrastructure for the collection, storage, and analysis of the spatial information. So far, these projects have been approached from the areas such as the civil engineering and the computer science perspectives. Nonetheless, in order for a GIS project to be successful, it should be approached from the management perspectives as well. In this paper, the authors discusses about the management issues such as the determination of priority of the sub-projects, the organizational structure that takes charge of the project and the evaluation of the performance of the project.

Since the bifurcating autoregressive (BAR) model was developed by Cowan and Staudte (1986) to analyze cell lineage data, a lot of research has been directed to BAR and its generalizations. Based mainly on the author's works, this paper is concerned with a contemporary review on the BAR in terms of an overview and perspectives. Specifically, bifurcating structure is extended to multi-cast tree and to branching tree structure. The AR(1) time series model of Cowan and Staudte (1986) is generalized to tree structured random processes. Branching correlations between individuals sharing the same parent are introduced and discussed. Various methods for estimating parameters and related asymptotics are also reviewed. Consequently, the paper aims to give a contemporary overview on the BAR model, providing some perspectives to the future works in this area.

Generating an action plan and obtaining commitment to achieve it is desired in organizations, but not always achieved. Whatever the reason, there is a room for an improved approach to decision making, so that people can arrive at a common understanding of a problem and commitment to action. Those are the purposes of a Decision Conferencing(DC). A DC, one example of single workstation-based GDSSs, is a two-day session attended by a group of people who attempt to resolve important issues of concern to their organization with the help of group facilitation techniques and decision analytic computer modelling. The interchange of differing perspectives on the issues is encouraged by the facilitator who attends to group processes but does not contribute to the content of discussions. Decision analysis provides a variety of structures for modelling the differing perspectives. Information and value judgements are incorporated in these models, whose results usually reveal new, higher-level perspectives on the issues. Information technology is needed to combine the part of the model and to facilitate on-the-spot replay of results. The experimental case study in this paper shows that how a DC can help a Korea's trading company to develop new, corporate level resource allocation strategies which are based on improved consensus among competing participants.
