This paper proposes an integrated management system for products of game software development. Those products generated over software life-cycle are generally huge in numbers, various in kinds and interconnected in relationships among them. Especially they are highly complex and tightly coupled each other because they are used to build another world which is composed of multi-modal data such as graphics, sound, logics and so on. Therefore it is critical to manage development products in an integrated manner to guarantee the quality of software. The proposed system is designed to provide project/requirement/configuration/traceability management capabilities and interfacing to CASE standards. To achieve the objective, it is based on data warehouse technologies which provide central repositories of heterogeneous data, multi-aspect reporting&analysis capabilities, traceability, verification, etc.

To prepare for the explosive increase in maintenance costs of bridges according to the aging of infrastructure, future maintenance costs of bridges should be predicted. For this purpose, the management status of bridges was investigated and modeled as the upper limit of the performance level and the target management level according to the life cycle. This paper proposes methodologies and procedures for estimating the bridge maintenance costs using two models and existing cost and performance prediction models that consist of unit repair cost model according to the safety score, performance degradation model of bridges, unit reconstruction cost, and average reconstruction time. To verify the applicability, future maintenance costs can be forecasted for specific management agency considering the number of bridges, degree of aging, and current management status. As a result, it is possible to obtain the maintenance cost and safety level of an individual bridge level for each year. In addition, by summing them up to the agency level, the average safety score, ratio of the safety level, inspection costs, repair costs, and reconstruction costs can be obtained. In a further study, the changes in maintenance costs can be analyzed according to the changes in the target management levels using the developed method. The optimal management level can be suggested by reviewing the results.

과거 우리나라 하천관리 정책은 이수와 치수 기능 위주로 개발됨에 따라 하천 수량이 감소하고 오염이 심화되는 등 하천환경이 계속적으로 악화되어 왔다. 시대가 변화함에 따라 하천환경 개선에 대한 패러다임과 사회적 요구의 변화로 인간과 자연이 더불어 살 수 있는 친환경적인 하천을 조성하고 훼손 또는 변화된 하천을 복원하는 노력이 필요하다. 하지만, 본래 자연상태의 하천으로 완벽하게 회복 될 수없다는 한계점이 있기 때문에 하천이 갖고 있는 하천공학적 기능을 최대한 유지하면서도 다양한 수생생물의 서식처의 기능도 되살아나게 해야 하는 복합적인 목적을 갖춰야 하며, 하천 수생생물의 서식처 복원을 위해서는 하천생태계에 필요한 환경유량의 정량적인 평가와 확보방안 및 공급방안의 검토가 동시에 필요하다. 본 연구에서는 하천유지유량이 생태계 기준으로 고시된 하천인 감천유역을 대상으로 물수급 분석을 통해 환경생태유량 확보할 수 있는 방안을 고려하고자 하였다. 물수급 분석을 위해 K-weap을 활용하였으며, 공급 우선순위, 저수지 운영 변화 등을 통해 제한된 수자원을 효율적으로 활용하여 방안을 제시하고자 하였다. 추후 하천 수생생물의 생애주기와 계절적 변화 등을 고려한다면, 더욱 합리적이고 지속가능한 환경생태유량 확보방안을 제시할수 있을 것으로 기대된다.

Since the year 2000, the need for an improvement of archival descriptions has been an increasing issue, due to the growing usage and amount of archival materials. Unlike the development of descriptions for paper records, however, the technological development and research for moving image descriptions has been limited due to its diversity and specificity. This research investigated the current status and the specificity of the moving image descriptions and also examined major international archival description cases. In-depth interviews with archival professionals were also conducted. Based on the findings, this study suggested the need for redefinition of and continuous research on the fundamental values of moving image information, moving image description and management based on digilog view points, the development of user-centric description and search aides, the creation of moving image values using a relevant information management system, and the improvement of moving image description elements throughout the life-cycle of the material.

Building information modeling (BIM)-based construction projects have increased and become more varied, and as such the management of BIM-based facility information is also increasingly important for facility maintenance. Information management, and specifically product data mapping, however, has some problems in the area of manual data entry and does not adequately consider the exchange requirements of facility maintenance. Therefore, it is necessary to introduce a method to improve the management of composite object information for BIM-based facility maintenance so that it can handle construction operation building information exchange (COBie) data for a composite object. Therefore, we present a method to map COBie data to related materials of a composite object. This research contributes to increasing the efficiency and accuracy of the required information mapping between a building model and product data using a BIM library through optimal BIM data adoption. Moreover, it allows for the creation and management of specific product data at the design development phase.

The purpose of this study was to promote an understanding of suicidal ideation and identify the factors that influence suicide ideation according to the life cycle of Korean adults. This study was a secondary analysis study using the Korea Health Panel 2016 data. Among adults over 19 years of age, 14,538 people with no missing values in suicidal ideation and influencing factors were classified into young adults (19-39 years old), middle-aged adults (40-64 years old), and the elderly (65 years or over). The data were analyzed by multiple logistic regression. The results showed that 2.9% (108 people) of young adults, 3.2% (181 people) of middle-aged adults, and 3.7% (80 people) of the elderly had suicide ideation over the past year. Factors influencing suicidal ideation by life cycle were anxiety, depression, drug use and quality of life for young adults, subjective health status, stress, anxiety, depression, drug use and quality of life for middle-aged adults. The factors affecting the elderly were body mass index, stress, anxiety, depression, and quality of life. Therefore, factors influencing suicidal ideation should be considered as a major factor for screening risk groups according to the life cycle, and differentiated intervention programs should be developed and provided to prevent and manage suicide in risk groups.
