There are more problems in distributing agricultural and special products than industrial products because they have such restrictions as seasonal fluctuation in the quantity, indeterminate and diverse shapes, many farm households, a small amount of shipment, and mandatory guide and maintenance. However, with social atmosphere called well-being, there are increasing concerns about inorganic agricultural products and direct trade with farmers. It is therefore urgent to stabilize the price of agricultural and special products and to correctly grasp and improve logistics activities for those dealing with agricultural and special products in order to supply fresh ones. This study aimed at examining logistics activities and the information technology level for agricultural and special products, determining how these factors affect logistics performance, and eventually suggesting a scheme to improve the logistics achievements for agricultural and special products. For this purpose, it selected information technology and logistics activity levels as independent variables and logistics performance as a dependent variable. The information technology level was measured for utility, holding level, and concern, respectively, and the logistics activity level was tested for the level of using the logistics information system in those companies concerned. From the above-mentioned findings, it is urgent to enhance distribution technology and its level immediately since distribution of agricultural and special products is poor in Korea and good distribution can contribute to a reduction of logistics costs or improvement of customer service.

The government is making great efforts to prevent crimes such as missing children by using public CCTVs. However, there is a shortage of operating manpower, weakening of concentration due to long-term concentration, and difficulty in tracking. In addition, applying real-time object search, re-identification, and tracking through a deep learning algorithm showed a phenomenon of increased parameters and insufficient memory for speed reduction due to complex network analysis. In this paper, we designed the network to improve speed and save memory through the application of Yolo v4, which can recognize real-time objects, and the application of Batch and TensorRT technology. In this thesis, based on the research on these advanced algorithms, OSNet re-ranking and K-reciprocal nearest neighbor for re-identification, Jaccard distance dissimilarity measurement algorithm for correlation, etc. are developed and used in the solution of CCTV national safety identification and tracking system. As a result, we propose a solution that can track objects by recognizing and re-identification objects in real-time within situation of a Korean public multi-CCTV environment through a set of algorithm combinations.

The practice of producing and transmitting TV programs with uneven loudness can harm audiences' welfare in the digital environment where audiences are entitled to be offered quality broadcasting service. The purpose of this paper is to investigate issues concerning the digital loudness policy institutionalized in Korea since May 2016, and to offer policy suggestions. This paper reviews previous studies on audience welfare in digital broadcasting, focusing on the close link between loudness policy and audience welfare. In order to explore the state of international policy, this paper examines loudness standards developed by international standardization organizations including ITU, ATSC, and EBU, along with loudness regulations in the US, the UK, Canada, Australia, Japan, and Korea, respectively. Based on the analysis, this paper suggests recommendations for policy makers and broadcasters. First, policies on mandating regular monitoring and establishing penality system should be established for broadcasters not to violate loudness standards. Second, broadcasters are recommended to collect audience feedback, to be equipped with loudness measuring devices, to offer personnel training programs, and to check the compliance of loudness standards when they outsource TV programs.

일반적으로 아웃소싱은 비용절감이나, 경쟁력 확보를 목적으로 기업 외부에서 필요한 자원, 기술력 및 해결방안 등을 찾는 경영기법으로, 단순용역업무에서부터 기업의 핵심기능인 IT 분야에 이르기까지 폭 넓게 활용되고 있다. 특히 IT 아웃소싱은 일상적인 정보시스템의 운영 및 개선, 네트워크 운영 및 어플리케이션의 유지/개선 등을 외부의 전문가에게 맡겨 점진적인 서비스 수준의 향상과 비용의 절감을 유도하고, 내부자원은 핵심역량에 집중시켜, 기업의 경쟁력을 높이는 하나의 경영수단으로 각광 받고 있다. 본 논문에서는 실제 통신서비스업체의 IT분야를 아웃소싱한 사례 연구를 통해서 IT 아웃소싱의 추진 시 필요한 제반사항과 절차, 추진배경등을 알아보고, 아웃소싱 성과를 결정하는 중요 요소인 서비스 성과측정 모델에 대해 연구하였다. '90 년대 후반 통신시장개방, 본격적인 경쟁체제 돌입등 핵심역량강화 차원에서 시작된 아웃소싱은 통신업체 국내최초의 사례로 처음부터 예상치못했던 어려움과 추진과정에서의 시행착오도 많이 겪었다. 또한, 선진외국사례의 아웃소싱 계약사례 및 서비스수준을 평가하기위한 서비스 수준 약정서등 국내 통신업체 환경에 맞게 잘 짤여지도록 수많은 검토와 사례 연구를 통해 계약을 체결할 수 있었으며, 아웃소싱이후 예상되었던 많은 문제점들을 해결하기위해 아웃소싱 인력들의 의욕수준을 높이기위한 직무 재교육, Incentive 제도 도입, 서비스와 관련된 제반 프로세스 재정립 등을 통하여 소기의 성과를 이룩할 수 있었다. 특히, 통신업체 IT 아웃소싱의 성공요인은 계약적 구조적 측면에 해당하는 적정한 서비스의 평가와 이에 상응하는 대가의 지급방안에 대한 것이고 양 사가 만족할 만한 성과를 내가 위해서는 수직적관계가 아니라 제휴관계로서의 Relationship 을 유지할 수 있도록 이 두가지 모두를 고려 해야만 성공적인 아웃소싱 추진에 한걸음 더 나아갈 것이며, 아울러 향후에도 아직 미흡한 분야인 IT 아웃소싱에서 적정수준의 대가지급 방안 및 바람직한 Relationship 에 영향을 미치는 여러 가지 요인에 대해서도 살펴 봄으로써 IT분야의 Outsourcing을 검토하거나, 추진할 때 도움이 될 수 있도록 하고자 한다.

Many facilities have been constructed due to the rapid development of science and economy, and the tendency for larger sizes and higher stories in constructing are being accelerated due to the development of technologies, and the efficient use of limited spaces. The safety problems of constructions are being frequently brought up. So, a technique by which the monitoring of the safety of constructions can be easily done must be developed as soon as possible. In this research an management system for structure's displacement using satellite survey was studied. The results of having established the management system for structure's displacement as a GPS positioning system were that data acquisition was easier than that from using normal survey equipment, and data from the satellite survey can be applied to the database of management system. The data of the GPS suey were rather large values to determine the safety of single stories, but can probably be used in establishing the management system using the structure's displacement.

This study attempts to investigate the IT utilization and e-business level of the small and medium companies in order to facilitate their e-commerce efforts. Results show that they have basic IT infrastructures such as internet and PC, but they use their IT resources mainly for office automations. Major problems with such low level of IT utilization are in their lack of manpower, skill, and fund. Considering above issues, web hosting service is believed as a good measure to alleviate their problems. Hence, this paper suggests that utilization of the web-based ASP can be a viable solution for the currently revealed issues. Also, development of creative IT application(business) cases and their advertizement can lead small and medium finns to more productive IT investments, which requires more diverse IT performance measurements such as BSC(balanced scorecard), other than traditional ROI.

The interest of the people in the radioactive contamination of the water has increased significantly and the study about analysis and management of radioactive materials are being actively conducted. And monitoring spots have been expanded to the range of public water as well as drinking water by publishing the rule of drinking water quality standards and examination in the Environmental Enforcement Ordinance No. 553 of Korea. In this study, US EPA was investigated as the foreign advanced cases and the way that is appropriate for the Korea was sought by analyzing investigate radionuclide, interval and management. As a result, in the selection part of investigate radionuclide, geological survey, status of nuclear power plants and the presence of the use of artificial radionuclides of the Korea should be investigated and additionally after the selection of a few radionuclides, the systems should be extended to cover all possible radionuclides by considering radioactive pollution levels in humans may be exposed due to the annual drinking water. In the part of the investigate interval, the concept(MCL, DL) should be set up for preventing concentration detection of above MCL and it needs to the maintenance and management. For example, when the concentration is more than MCL, it should be investigated on a quarterly and when the concentration is lower than MCL, it should be investigated to each different interval and management. And the US EPA divided the management area and make the roadmap for managing drinking water. The each classified area has been organized to match the state budget and labor force and the individual data have been managed effectively by HPGe, the NaI, TLD and so on.
