해상에서의 선박 임장임검과 불심검문의 법적성격과 강제력을 수반한 영장 없는 선박 임장임검과 불심검문의 가능성 및 그 허용범위의 문제를 특히 미국 및 일본의 경우와 비교하여 고찰하였다. 선박의 임장임겁이나 해상에서의 선박에 대한 불심검문이 원칙적으로 육상의 불심검문과 같은 성격을 갖지만, 선박의 특수성과 육상과는 다른 해상에서의 상황의 특수성을 고려 한다면, 선박의 임장임검이나 해상에서의 불심검문이 육상의 불심검문과 같이 항상 임의적으로 이루어져야 한다고 보기는 어려운 측면이 있는 것으로 판단된다.

In this paper, the major changes of the national inspection in respect of the KAERI nuclear facilities were summarized. The frequency of the national inspection was decreased since the amendment of the Notification of the NSSC on the national inspection. But the national inspection broadened its scope and its implementation procedures and criteria were not clear. So, it is necessary to establish and enhance the national inspection system including the implementing guides and criteria. In addition, the internal regulation of the nuclear material accountancy for the nuclear facilities should be approved from the NSSC and observed by the KAERI in accordance with the national law. As the Notification of the NSSC on the national inspection was amended in Sep. 2014, it need to be revised to reflect the detail accountancy procedures and the preparation of the national inspection. So, KAERI will revise it to meet the international and national requirements as well as to implement the safeguards effectively at facility level.

오늘날 금융이 급격하게 변화함에 따라 e-뱅킹 시스템을 개발하는 프로젝트의 구축 기간은 점차 짧아지고 있고, 이로 인해 구축에서의 위험 또한 증가하고 있다. 때문에 금융사는 프로젝트 개발 중에도 시스템의 품질을 검토하길 요구한다. 하지만 개발사 입장에서 이와 같은 추가적인 품질 검토는 투입되는 노력으로 인해 개발을 지연시키는 요인이 되고, 결국 금융사와 개발사의 갈등을 야기한다. 이와 같은 문제를 해결하기 위해 이 논문에서는 e-뱅킹 시스템에 특성을 고려하여 우선순위를 정의하고, 이를 통해 효율적인 코드 인스펙션을 위한 범위 우선순위 판단 기준을 설계한다. 설계된 코드 인스펙션 범위를 이용하여 적은 노력으로 효율적인 코드 인스펙션을 수행할 수 있으며, 해당 범위를 활용하여 좀 더 고품질의 프로덕트를 개발할 수 있을 것으로 기대된다.

In South Korea, there is no consideration for increasing labor costs and price fluctuation regarding the commission for a flight inspection. Because this causes a deficit in the flight inspection related operation, the cost system should be improved. Therefore, this research considers the first cost analysis in order to calculate a proper flight inspection commission through three different types of cost making methods. Moreover, as flight inspections are held by flights and human labors, labor costs are included as the main operation cost. According to the research, it is analyzed that the total cost to process flight inspection operations is decided by the scope of aircraft operation.

Recently, the scope of the smart factory has been expanded, and process research to minimize the part that requires manpower in many processes is increasing. In the case of detecting defects in the appearance of small products, precise verification using a vision system is required. Reliability and speed of inspection are inefficient for human inspection. In this paper, we propose an algorithm for inspecting product appearance defects using a machine vision system. In the case of the remote control targeted in this paper, the appearance is different for each product. Due to the characteristics of the remote control product, the data obtained using two cameras is compared with the master data after denoising and stitching steps are completed. When the algorithm presented in this paper is used, it is possible to detect defects in a shorter time and more accurately compared to the existing human inspection.

The variable sampling inspection scheme with screening for the purpose of assuring the upper limit of maximum expected surplus loss after inspection has been proposed. In this inspection scheme, it has been assumed that a product lot consists of products manufactured through a single production line and lot quality characteristics follow a normal distribution. In the previous literature with respect to inspection schemes, it has been commonly assumed that lot quality characteristics obey a single normal distribution under the condition that all products are manufactured in the same condition. On the other hand, the production line is designed in order that the workload of respective processes becomes uniform from the viewpoint of line balancing. One of the solutions for the bottleneck process is to arrange the workshops in parallel. The lot quality characteristics from such a production line with the process consisting of some parallel workshops might not follow strictly the single normal distribution. Therefore, we expand an applicable scope of the above mentioned variable sampling inspection scheme with screening in this article. Concretely, we consider the variable sampling inspection with screening for the purpose of assuring the upper limit of average outgoing surplus quality loss in the production lots when the lot quality follows the mixed normal distribution.

As North Korea signed 'the Korea Peninsula Non-Nuclearization Joint Declaration' at the end of last year as well as full-scope safeguards agreement with the IAEA in Jan.30 1992, her nuclear activity was incorporated into the international monitoring system and opportunities were arranged to .obstruct her nuclear weapon development and nuclear material diversion, which have been international issues up to recent years. However, achieving goals of the Joint Declaration and safeguards agreement should presuppose North Korea's sincerity toward the abandonment of nuclear weapon development. In this study, first of all, her nuclear policy, current situation of nuclear development and the capability of nuclear development are analyzed. Also, based on the analysis. attempts have been made to find methods of effective performance of the South-North Korea mutual nuclear inspection and the suggested methods are as follows; 1) Analysis of the limits of IAEA inspection and suggestion of its supplementary strategies 2) Securing and training professional inspectors for the South-North mutual inspection 3) Establishment of the verification technology to detect nuclear material diversion.

Due to the aging of a building, 38.8% (about 2.82 million buildings) of the total buildings are old for more than 30 years after completion and are located in a blind spot for an inspection, except for buildings subject to regular legal inspection (about 3%). Such existing buildings require users to self-inspect themselves and make efforts to take preemptive risks. The scope of this study was defined as the general public's visual self-inspection of buildings and was limited to structural members that affect the structural stability of old buildings. This study categorized possible damage to reinforced concrete to check the structural safety of buildings and proposed a checklist to prevent the damage. A damage assessment methodology was presented during the inspection, and a self-inspection scenario was tested through a chatbot connection. It is believed that it can increase the accessibility and convenience of non-experts and induce equalized results when performing inspections, according to the chatbot guide.

자동차는 발명 초기 형태로 부터 많은 발전과 변형을 거듭하여 현재의 형태에 이르기 까지 인간의 활동 영역을 넓혀 주고 있다. 자동차의 전자 부품중 하나인 정션 박스를 종래에는 사람이 직접 육안으로 검사하여 오판을 하거나 검사의 속도가 느린 문제점이 있었다. 이를 보완하여 빠르고 정확하게 정션 박스 검사를 하기 위하여 비전 시스템(Vision System)을 이용하여 공정을 자동화 하는 방법을 제시하였다. 본 논문은 정션 박스에 삽입된 퓨즈(Fuse)와 릴레이(Relay)의 색상과 표면의 패턴을 검사하여 이상 유/무 및 결함을 자동으로 검사한다. 불량 검출의 성능을 평가하기 위하여 정션 박스를 가지고 시스템의 성능을 평가한 결과, 100%의 인식률을 나타내었고 이를 산업체에 적용하여 신속하고 정확한 검사가 가능함을 보였다.

This study presents a computer vision-based approach for representing time evolution of structural damages leveraging a database of inspection images. Spatially incoherent but temporally sorted archival images captured by robotic cameras are exploited to represent the damage evolution over a long period of time. An access to a sequence of time-stamped inspection data recording the damage growth dynamics is premised to this end. Identification of a structural defect in the most recent inspection data set triggers an exhaustive search into the images collected during the previous inspections looking for correspondences based on spatial proximity. This is followed by a view synthesis from multiple candidate images resulting in a single reconstruction for each inspection round. Cracks on concrete surface are used as a case study to demonstrate the feasibility of this approach. Once the chronology is established, the damage severity is quantified at various levels of time scale documenting its progression through time. The proposed scheme enables the prediction of damage severity at a future point in time providing a scope for preemptive measures against imminent structural failure. On the whole, it is believed that the present study will immensely benefit the structural inspectors by introducing the time dimension into the autonomous condition assessment pipeline.
