Port State Control (PSC) is the inspection of foreign ships in national ports for the purpose of verifying th\ulcorner the condition of the ships and its equipments comply with the requirement of international conventions and the ship is manned and operated in compliance with applicable international laws. On the other hand, check items in PSC are nearly similar to periodical survey of Classification Societies, because they have the same background regarding safety and maritime pollution prevention. The purpose of this study is to develope computer-aided information systems for ship inspection item which is useful for effective implementation of Port State Control. For this work, the status of PSC is reviewed, and the related scheme of ship survey system in Classification Societies is investigated. On these bases, a computer software integrated database system and object-oriented technique is developed. The developed system is expected helpful to establish and maintain an effective system of Port State Control.

The specialty of Construction Manager's work is largely depends on the project progress stage and the type of management work. However, at present, career management system manages only the type and duration of the construction project, disregarding specialty and competence. However, in order to select a right construction manager for the client's needs or project characteristics, career management should be subdivided and managed according to the project progress stages or the types of management. In addition, this career management plan is essential for construction managers to receive appropriate wages for their careers and competences. Therefore, this study proposes a classification system for the integration of career, work, and competency to promote effective career management.

It is challenging to build the integrated information system for a large scale cooperative R & D project. To develop the aircraft program which especially has several leading agencies and is supported by many demestic/foreign participating companies, the common data flow in harmony is the core factor to achieve a development goal. For this, the development are carried out maintaining the existing management systems of agencies and companies. As a first step, the standard for the common data information and the classification category of technical data are defined. Second, the work flow standards are also set. Based on the foundation, the efficient technical data management system are built including the function of storage, inquiry, revision, link, approval, submission, etc.

Purpose : This study is a descriptive research study to establish basic data for stable operation of dementia relief center as a part of national responsibility system for dementia and to establish the role of the professional workforce. Methods : This study is a survey study involving 126 nurses working at 19 dementia relief centers. The collected data were analyzed using the SPSS/WIN 23.0. Results : The importance tasks that nurses think of were Dementia Diagnosis, Counseling, Register and Classification and Dementia Preventive Projects. In addition, tasks that showed high performance were in the order of Dementia Diagnosis, Counseling, Register and Classification, Management of Dementia subjects. As a result, the final items of work areas and contents included 45 subcategories of work content for eight work areas. Conclusion : Through this study, it was possible to investigate the overall work area and content of nurses at the Dementia relief Center. It is necessary to develop a work description suitable for nurses who are medical personnel specializing in dementia safety centers. It is necessary to develop a work description suitable for nurses who are medical personnel specializing in dementia safety centers. In connection with the purpose of establishing the centers for disease control and prevention, it is necessary to operate a systematic and continuous program to manage dementia patients and those with mild cognitive impairment in the community.

The association of poor body postures with pains or symptoms of musculoskeletal discorders has been reported by many researchers. An ergonomic evaluation of postural stresses as well as biomechanical stresses is also important especially when a job involves highly repetitive or prolonged poor body postures. The human body is divided into five parts: shoulder/upper arm, lower arm/wrist, back, neck, lower extremities. A work-sampling based macropostural classification system was developed to characterize various postures in this study. Application of the posture classification schema developed in this study to 7 automobile assembly tasks showed that the schema can be used as a tool to didntify the operation and tasks involving highly stressful body postures. This posture classification schema can also be applied as a basis for quantitive evaluating the workload of manual task.

본 논문에서는 광고영상에서 동일한 광고의 다수 매체(신문, 잡지)에 실리는 판형을 효율적으로 관리하는 데이터베이스 시스템을 구축하기 위한 유사광고를 분류하는 시스템을 제안한다. 현재, 신문광고를 데이터베이스화하는 작업은 사람이 직접 매체를 하나씩 스캐너를 이용하여 영상데이터를 획득한 후 포토샵이나 그림판과 같은 이미지 편집 툴을 이용하여 광고영역을 잘라내고 저장하고, 각 광고에 따른 날짜정보, 매체정보, 페이지정보, 광고가 실린 면의 종류, 크기정보 등을 일일이 기록, 저장하기 때문에 비능률적이고 비효율적인 업무형태로 많은 시간과 인력의 낭비를 초래하고 있다. 이러한 문제를 해결하기 위하여 디지털 카메라를 이용하여 신문영상을 획득하고, 영상 전처리 과정을 통하여 광고후보영역을 추출하며, 신문매체광고가 가지는 특성에 따라 광고후보영역을 분류한다. 따라서 본 시스템은 모든 광고영상의 유사성을 비교하여 신규광고인지, 기존의 광고인지를 분류하여 데이터베이스화 한다.

At present, GEOBIA (Geographic Object-based Image Analysis), heir of OBIA (Object-based Image Analysis), is regarded as an important methodology by object-oriented paradigm for remote sensing, dealing with geo-objects related to image segmentation and classification in the different view point of pixel-based processing. This also helps to directly link to GIS applications. Thus, GEOBIA software is on the booming. The main theme of this study is to look into the applicability of geo-spatial processing open source to GEOBIA. However, there is no few fully featured open source for GEOBIA which needs complicated schemes and algorithms, till It was carried out to implement a preliminary system for GEOBIA running an integrated and user-oriented environment. This work was performed by using various open sources such as OTB or PostgreSQL/PostGIS. Some points are different from the widely-used proprietary GEOBIA software. In this system, geo-objects are not file-based ones, but tightly linked with GIS layers in spatial database management system. The mean shift algorithm with parameters associated with spatial similarities or homogeneities is used for image segmentation. For classification process in this work, tree-based model of hierarchical network composing parent and child nodes is implemented by attribute join in the semi-automatic mode, unlike traditional image-based classification. Of course, this integrated GEOBIA system is on the progressing stage, and further works are necessary. It is expected that this approach helps to develop and to extend new applications such as urban mapping or change detection linked to GIS data sets using GEOBIA.

This paper proposes a fault detection system to detect the strip rupture in six-high stand Cold Rolling Mills based on transient current signal of an electrical motor. For this work, signal smoothing technique is used to highlight precise feature between normal and fault condition. Subtracting the smoothed signal from the original signal gives the residuals that contains the information related to the normal or faulty condition. Using residual signal, discrete wavelet transform is performed and acquire the signal presenting fault feature well. Also, feature extraction and classification are executed by using PCA, KPCA and SVM. The actual data is acquired from POSCO for validating the proposed method.

This study is to evaluate the classification system of rural-villages remodeling components which is provided for improving the quality of life for rural community by improvement of settlement environment. To achieve this, rural-villages remodeling components are classified according to the spatial structure of rural area through analysis of literature, then we have examined the applicability through case studies after modification work which is based on experts's discussion and rearrangement by pilot investigation of researcher. In the classification system of rural-villages remodeling classified productivity area, residential area, community area in first group and this classification is divided into 6 space to production, 4 space to residence, 5 space to community in second group by literature search, pilot investigation of researcher and field survey. The subject elements surveyed a total of 123 through the literature search, additionally, 1 element at a space to production and space to community in field survey for types in zoning cases. As a result, categories and items are decided that it is included 125 target elements.
