In order to understand a record, not only the contents of the record but also the production background and work context of the record must be grasped. It also requires a function that makes it easy to find related records scattered across various departments and agencies. Accordingly, the 'linkage' of information in archival information services is becoming more important. NAK also emphasizes 'linkage' as a search service function of the archives management system, but some problems were identified at the National Archives Portal Service (NAPS) such as a lack of linkage with authority data, disruption of internal service, and absence of linkage with other related organizations. To solve the limitations of the NAPS, we selected and analyzed advanced record management institutions that have built an ideal linkage service; checked the overall linkage structure of these institutions; and identified characteristics that could not be seen by other institutions. Also, elements that can be adopted from the NAPS were derived. Next, the current status of the NAPS linkage structure was analyzed to identify the parts that were not linked and the items that need to be improved in the linkage method, and specific advancement plans were suggested to solve these problems. The purpose of this study is to increase users' satisfaction with search and to advance the accessibility and utilization of records and internal services through improved linkage services of NAPS.

소비자의 욕구와 개성화, 그리고 시장경쟁력에서 생산체제가 변화되면서 기업들의 물류환경여건도 변화를 가져와 물류가 기업들에게 당면한 주요 과제가 되었다. 사회 간접자본의 부족으로 인한 도로, 항만 등의 정체현상이 심화되고 3D업종에 속하는 물류부문은 더욱 인력난을 겪게 되면서 물류비상승이라는 부담을 안게 되었다. 그리고, 컴퓨터, 정보통신기술 등과 같은 첨단의 기술혁신이 이루어 집에 따라 컴퓨터 및 각종 기기들의 연결이 가능해지면서 물류정보시스템 구축이 활발하게 이루어져 가고 있다. 그러나, 이러한 현실에도 불구하고 기업들은 이에 대한 효율적인 대처 방안을 마련하지 못하고 물류에 대한 인식조차 못하고 있거나 잘못 이해하고 있는 실정이다. 본 논문은 이러한 문제점을 인식하여 물류정보시스템의 활용수준과 물류활동 연계 그리고 물류전략에 대한 이론을 정립하고 이를 근거하여 나라 기업률이 물류를 어떻게 인식하고 있는가를 물류정보시스템의 활용수준, 물류활동연계, 물류전략 등의 변수를 도입, 측정하여 봄으로써 우리나라 기업의 물류에 대한 문제점들을 규명하고 앞으로 물류의 능률적인 실시를 위한 올바른 방향을 제시하는데 그 목적을 두고 있다. 실종분석 결과 물류성과에 대한 물류정보시스템 활용수준과 물류연계수준은 물류성과에 영향을 미치는 것으로 나타났다. 그리고, 물류 기능별 정보시스템 활용수준과 물류차별화 전략이 물류성과에 상호작용 효과를 보이는 지를 알아본 결과 상호작용효과가 있는 것으로 나타났다.

The aim of this study is to reveal the effects of government and public electronic procurement on the private sector's productivity and technical inefficiency. Three cases are analyzed. The first scenario is that the government just appears as a new consumer to enterprises. Simply participating as a new consumer to enterprises reveals that government does not contribute to the private sector's productivity or improve technical efficiency. The second case is one where the government publicly procures the private sector's service or goods using IT technologies. It is revealed that government contribute to improve the private sector's productivity and reduce inefficiency. The last case is where the government demands business to connect to governments using new IT technologies. The government demands to adopt the IT technology for connection results in improved productivity and efficiencies in the private sectors.

The defense industry has recently been developed for boosting exports of weapon systems. The survey and analysis of the quality level are required to form a relevant policy for expanding the defense industry. Evaluation indices and modeling of the quality level for manufacturers are used to examine the status of internal quality management and quality management system in order to enhance the overall quality level and establish a quality policy in the field of military supplies. There were some restrictions to apply all aspects of the quality level in the previous model. This paper deals with the research and analysis of other types of model for evaluating the quality level, including the model used in the defense field. By enhancing the close link between procedure indices and performance indices, the research and analysis could be conducted objectively and intuitively. The developed and improved model and indices will be used in the next survey of the quality level for manufacturers of military supplies. The survey results will be used to establish effective government quality management policy.

Recently, livestock farms in Korea are introducing data-based technologies to improve productivity, such as livestock environment and breeding management, safe livestock production, and animal welfare. In addition, the government has been conducting a smart livestock distribution project since 2017 through the modernization of ICT-based livestock facilities in order to improve the productivity of livestock products and improve the livestock environment as a policy. However, the current smart livestock house has limitations in connection, diversity, and integration between monitoring and control. Therefore, in order to intelligently systemize all processes of livestock with intelligent algorithms and remote control in order to link and integrate various monitoring and control, the Internet of Things, big data, artificial intelligence, cloud computing, and mobile It is necessary to develop a smart livestock system. In this study, domestic and foreign research trends related to smart livestock based on intelligent information technology were introduced and the limitations of domestic application of advanced technologies were analyzed. Finally, future intelligent information technology applicable to the livestock field was examined.

In this paper, we perform a numerical analysis to evaluate the potential of fault reactivation during gas production from hydrate bearing sediments and the moment magnitude of induced seismicity. For the numerical analysis, sequential coupling of TOUGH+Hydrate and FLAC3D was used and the change in effective stress and consequent geomechanical deformation including fault reactivation was simulated by assuming that Mohr-Coulomb shear resistance criterion is valid. From the test production simulation of 30 days, we showed that pore pressure reduction as well as effective stress change hardly induces the fault reactivation in the vicinity of a production well. We also investigated the influence of stress state conditions to a fault reactivation, and showed that normal fault stress regime, where vertical stress is relatively greater than horizontal, may have the largest potential for the reactivation. We tested one simulation that earthquake can be induced during gas production and calculated the moment magnitude of the seismicity. Our calculation presented that all the magnitudes from the calculation were negative values, which indicates that induced earthquakes can be grouped into micro-seismic and as small as hardly perceived by human beings. However, it should be noted that the current simulation was carried out using the highly simplified geometric model and assumptions such that the further simulations for a scheduled test production and commercial scale production considering complex geometric conditions may produce different results.

In this paper, we use panel dataset from Korean linked worker-firm to analyse the effects of the workforce age structure on the productivity or labor costs. We measure 'labor productivity' as added value per capita, 'cost of labor' as labor cost per capita and estimate a dynamic panel model to study the effects of the workforce age structure on the productivity or labor costs. Empirical analysis results show that the workforce age structure is positively related to productivity and labor costs, but only up to the aged of 35-39. That is, we find that an increase in the proportion of younger workers or elder workers rather than the aged 35-39 has a negative effect on productivity and labor cost. In particular, the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 50 or older is increased instead of the aged 35-39 is higher than the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 30 or younger is increased instead of the aged 35-39. Our results exhibit that it is reasonable for firms to worry about declining productivity of elderly workers, whereas firms already used older workers efficiently, such as by adjusting their labor costs.
