최근 정보기술의 발달로, 군에서도 정보시스템의 활용이 활발히 이루어지고 있다. 특히 포병화력지원부대에서는 임무수행을 위한 정보시스템으로 전술사격지휘 시스템(BTCS-A1)을 활용하고 있다. 하지만, BTCS-A1이 각종 정보를 제공하고 사격지휘 절차를 자동화하여 사격시간을 단축하는 등 임무수행에 도움이 되는 정보시스템으로 인식되고는 있지만, 시스템이 제공하는 효과성이나 포병부대의 성공적인 임무수행을 위한 기여정도에는 여전히 논쟁의 여지가 있다. 따라서, 본 연구는 적합구조화이론(Adaptive Structuration Theory)에 근거하여 BTCS-A1의 활용을 전유(Appropriation)로 개념화한 후, BTCS-A1의 전유가 포병 사격지휘팀 구성원의 과업성과(Task Performance)에 어떻게 영향을 주는지를 조사하였다. 또한, BTCS-A1의 전유에 영향을 주는 다양한 요인으로 기술적 특성(정보시스템 품질), 조직환경 요인(조직압력), 사격지휘팀의 내부 환경요인(팀 학습풍토, 팀 권한위임풍토)을 고려하여 연구가설과 모형을 제시하였다. 설문분석 결과, 조직압력, 팀 학습풍토, 팀 권한위임풍토가 정보시스템의 전유를 촉진하였으며 정보시스템의 전유는 과업성과를 개선한다는 결과를 얻었다. 반면 정보시스템품질은 정보시스템의 전유에 유의미한 영향이 없는 것으로 나타났다. 본 연구는 BTCS-A1을 사용하는 포병부대가 정보시스템의 활용을 통하여 과업성과를 향상하기 위해서는 정보시스템의 제공과 사용의 강조뿐만 아니라 시스템 활용을 위한 상급자의 관심과 제도적 장치의 지속적인 고려가 필요하고, 팀 학습풍토와 권한위임풍토의 여건을 마련해주는 조치가 중요하다는 시사점을 발견하였다.

The study was aimed at developing an independent hospice center model that would be best suited for Korea based on a literature review and the current status of local and international hospices. For the study, five local and six international hospice organizations were surveyed. Components of the hospice center model include philosophy, purpose, resources (workers, facilities, and equipment), allocation of resources, management, financial support and hospice team service. The following is a summary of the developed model: Philosophies for the hospice center were set as follows: based on the dignity of human life and humanism, help patients spend the rest of their days in a meaningful way and accept life positively. On the staff side, to pursue a team-oriented holistic approach to improve comfort and quality of life for terminally ill persons and their families. The hospice center should have 20 beds with single, two, and four bed rooms. The center should employ, either on a part-time or full-time basis, a center director, nurses, doctors, chaplains, social workers, pharmacists, dieticians, therapists, and volunteers. In addition, it will need an administrative staff, facility managers and nurses aides. The hospice should also be equipped with facilities for patients, their families, and team members, furnished with equipment and goods at the same level of a hospital. represented by a center director who reports to a board and an advisory committee. Also, the center director administers a steering committee and five departments, namely, Administration, Nursing Service, Social Welfare, Religious Services, and Medical Service. Furthermore, the center should be able to utilize a direct and support delivery systems. The direct delivery system allows the hospice center to receive requests from, or transfer patients to, hospitals, clinics, other hospice organizations (by type), public health centers, religious organizations, social welfare organizations, patients, and their guardians. On the other hand, the support delivery system provides a link to outside facilities of various medical suppliers. In terms of management, details were made with regards to personnel management, records, infection control, safety, supplies and quality management. For financial support, some form of medical insurance coverage for hospice services, ways to promote a donation system and fund raising were examined. Hospice team service to be provided by the hospice center was categorized into assessment, physical care, emotional care, spiritual care, bereavement service, medication, education and demonstrations, medical supplies rental, request service, volunteer service, and respite service. Based on the results, the study has drawn up the following suggestions: 1. The proposed model for a hospice center as presented in the study needs to be tested with a pilot project. 2. Studies on criteria for legal approval and license for a hospice center need to be conducted to develop policies. 3. Studies on developing a hospice charge system and hospice standards that meet local conditions in Korea need to be conducted.

In this paper, we investigate the requirements of QPA(Quality Process Audit), which is a process quality audit system for secondary defense contractors, compared with those of DQMS(Defense Quality Management System). And evaluate whether the deployment of QPA meets the DQMS certification requirements through the case example of Company H. The evaluation items of QPA are composed of five categories such as Material Management, Incoming Inspection, Manufacturing Process, Product Evaluation, and Packaging Management. The QPA requirements are mainly related to the chapter 7(support) and chapter 8(operation) of DQMS standards. In this view point, QPA can be expected as an effective audit for suppliers preparing for DQMS certification. In the case example, we evaluate the results and effects of improvement due to QPA and compare it with the case of DQMS. QPA can be used as appropriate quality management standards of secondary and tertiary defense contractors and can provide the basis guidelines for the preparation of implementation steps in DQMS certification.

Value Engineering has been recognized as one of the construction management techniques for improving the value and benefits of whole project. However, due to the lack of the past data and inefficient free-thinking techniques, the idea generation during VE workshop is still inefficient and ineffective. Even though various studies related to theoretical methodology and technical systems relevant to database were conducted, VE team still mainly rely on their experience for idea generation. With this regard, this study suggests an approach of BIM-based idea bank and assesses its effectiveness by interviewing 20 VE experts in the industry. This approach covers the three steps of idea generation, consisting of 1) Developing BIM based VE database, 2) Generating VE ideas, 3) Updating VE ideas. The result showed that the proposed approach has great potentials to support VE team and improve the quality of VE ideas during creativity phase.

Purpose: Although the price reduction policy is established for military supplies, it is more focused on general military items. Therefore, it is hard to apply the current price reduction policy directly to the major weapon system. The purpose of this study is to develop an evaluation model which generates appropriate outputs for price reduction of military supplies. Methods: To improve the current policy, we first analyze the relevant policies of price reduction of similar organizations. We gather the opinions of related organization through survey including DAPA, Logistics Command, DTaQ and Defense industry companies. Then, we develop a price reduction model based on the analytic hierarchical process(AHP) method to find out important factors for price reduction. Results: The results of AHP analysis show that the important factors when applying price reduction of military supplies. From the analysis, the proposed method effectively generates the amounts of price reduction for the nonconformance items. Conclusion: The results of this research will be used as guidelines to improve military supplies policy of price reduction.

Purpose: This paper has examined the impact of open innovation business model in technology commercialization with the data from 30 companies of manufacturing firms in South Korea. Methods: The findings provide support for distinguishing five hypotheses relating to development time, IP management, sales, firm size and R&D intensity. To test the hypotheses, data were collected using via e-mail and fax. Small and medium-sized (less than 300 employees) and large industrial firms were chosen for this study. Results: The result shows that openness in its business model is positively associated with successful technology commercialization. Conclusion: The major findings and the implications are: First, as the business model gets more open, development period of technology will be more favorable which gets benefit from rising costs of innovation. Second, as the business model gets more open, large portion of sales are created from new products. Thus, the problem of shorter product life in the market which affects large portion of market revenue can be solved through an open business model. Third, in general, R&D intensity, firm size and the level of IP management affect determination of business model types. The findings also suggest that companies need to increasingly address their external technology exploitation process instead of focusing on their internal innovation processes.

Although many research efforts have been conducted to address the effect of crew members' work skills (e.g., technical and planning skills) on work performance (e.g., work duration and quality) in construction projects, the relationship between skill and performance has generated a great deal of controversy in the field of management (Inkpen and Crossan 1995). This controversy can lead to under- or over-estimations of the overall project schedule, and can make it difficult for project managers to implement appropriate managerial policies for enhancing project performance. To address this issue, the following aspects need to be considered: (a) work performances are determined not only by individual-level work skill but also by the group-level work skill affected by work team members, each member's role, and any working behavior pattern; (b) work planning has significant effects on to what extent work skill enhances performance; and (c) different types of activities in construction require different types of work, skill, and team composition. This research, therefore, develops a system dynamics (SD) model to analyze the effects of both individual-and group-level (i.e., multi-level) skill on performances by utilizing the advantages of SD in capturing a feedback process and state changes, especially in human factors (e.g., attitude, ability, and behavior). The model incorporates: (a) a multi-level skill evolution and relevant behavior development mechanism within a work group; (b) the interaction among work planning, a crew's skill-learning, skill manifestation, and performances; and (c) the different work characteristics of each activity. This model can be utilized to implement appropriate work planning (e.g., work scope and work schedule) and crew management policies (e.g., work team composition and decision of each worker's role) with an awareness of crew's skill and work performance. Understanding the different characteristics of each activity can also support project managers in applying strategic work planning and crew management for a corresponding activity, which may enhance each activity's performance, as well as the overall project performance.
