맞벌이 가정이 증가함에 따라 영유아, 장애인, 노인 등의 사회적 약자를 낮시간 동안 보육/보호하는 데이케어 센터의 수요가 증가하고 있다. 데이케어 센터는 센터 경쟁력 확보 및 보호자 만족도 제고를 위해서 피보호자의 일상 사진을 제공하는 곳이 대부분이다. 하지만 데이케어 센터의 직원이 다수의 사람에 대한 사진을 촬영 및 선별해서 메시지를 전송하는 일은 데이케어 센터 본연의 업무를 방해할 수 있다. 따라서 본 논문에서는 사진 선별을 업무 부담을 완화시키는데 도움을 줄 수 있는 얼굴 특징 기반 사진 자동분류하는 시스템을 개발한다. 제안한 방법에서는 얼굴 특징 추출 기법과 클러스터링 알고리즘인 DBSCAN을 이용하여 얼굴기준 사진 분류시스템을 설계하엿다. 특히, OpenCV와 face recognition 라이브러리를 이용하여 카메라로 촬영된 사진 속의 얼굴 객체를 인식하고 얼굴사진을 저정한 후 얼굴의 특징을 추출한다.

With the increase in the number of ICT industry workers, there is a demand for research on preventing VDT syndrome. However, existing posture correction products mostly rely heavily on cameras or sensors in wearable devices. In this paper, we have developed a posture correction system that utilizes built-in cameras and circular pressure sensors to collect posture information. Additionally, the system provides a personalized service by capturing the correct posture of the user initially and monitoring the user's posture based on that input. By precisely correcting postures during users' daily tasks, this system aims to prevent and improve VDT syndrome, ultimately enhancing the efficiency of ICT industry workers.

Objective : The purpose of this study was to investigate the awareness of job task importance and performance of occupational therapists in the community care system for the elderly. Methods : We conducted an online questionnaire survey of 152 occupational therapists nationwide from May 31, to June 24, 2019. General characteristics and institutional awareness, role and performance awareness were analyzed by descriptive statistics. One way ANOVA were conducted to compare the differences of working days, working places, and the field of work. Results : The recognition of the community care system for the elderly was low at 2.93 ± 1.0 but the importance of the community care system was 3.94 ± 0.7 and the importance of the occupational therapist in the system was 4.34 ± 0.7. Fall prevention (4.63 ± 0.7) was the most important in occupational therapist's jobs, and performance was high in instrumental activity daily living training (3.94 ± 0.8) and physical function training (3.94 ± 0.8). Conclusion : This study can be presented as basic data on job task importance and performance awareness of occupational therapists in the elderly community care system. In addition, it is expected to be used as basic data for establishing the role of occupational therapist in the elderly community care system.

Software agents reduce human involvement to a certain extent by automating routine tasks. However, most of agents have assisted with only a few steps in the multi-steps process of electronic transactions. In order to help users with the important steps in the electronic transactions, software agents need to persuade other parties to act in particular ways. While negotiations have many shapes and forms, this paper focuses on a particular class of negotiation, that is competitive business environment based negotiation. For negotiation with other parties in this contort, it is necessary for autonomous agents to consider environmental variables-the number of competitors, the number of negotiation parties, the maximum time by which they must finish their jobs, and user's preferences. Previous negotiation decision functions for the automated negotiation have used only time or the static numbs of negotiating parties as negotiation criteria, although competitive business environment should include potential competitors who can snatch negotiation parties away. This paper attempts to evaluate the performance of a negotiation decision function that considers the potential competitors in competitive market environment as well as that of a negotiation decision function that does not. For this evaluation, this study adopts the electronic marketplace as an application domain because many buyers and sellers compete for limited resources in the marketplace.

The COVID-19 pandemic reminded us again of the importance of essential workers who perform their roles in maintaining the stability of people's daily lives worldwide. Therefore, the International Maritime Organization and overseas countries designated seafarers as essential workers and proposed relevant measures for their protection to enable them to perform their role. In particular, the International Maritime Organization (IMO) urges related associations and member states to support safe boarding and disembarkation of seafarers. However, Seafarers were restricted from boarding or disembarking, shore leave and hospital treatment in certain countries owing to extreme nationalism. This study compares and analyzes the cases of international organizations and major overseas countries to provide a logical basis for the protection of seafarers who play an essential role in the safety of the global supply chain despite the COVID-19 pandemic. This study identifies the need to protect seafarers and their roles as essential workers in the shipping industry and suggests necessary aspects and institutional improvement measures for improving seafarers' working environment to strengthen the shipping industry's resilience. This study is expected to serve as future basic data for national policies aimed at reflecting the roles of seafarers as essential workers and the need to protect them.

Walking behaviors are one of the most basic transport modes in daily life. As a result, the efforts and concerns on pedestrians are consistently increased. This study tried to reveal significant factors for pedestrian volumes through structural equation models and compare the impacts of the whole time of day, off-peak time, peak time on the pedestrian volumes. The results of the analysis show that commercial business factors, accessibility factors, walking environment factors are the most significant factors that increase pedestrian volumes. Whereas, housing factors do not contribute to increase the pedestrian volumes. In the non-peak time, the weight of commercial business factors is higher than the whole time of day, while the weight housing factors, accessibility factors, walking environment factors are lower. In the peak time, however, the weight of commercial business factors decreases rather than the whole time of day, while the weight of the other factors increase.

This study focused on user centered design methodology on mobile service design, Especially we designed business supporting service for sale persons with heavy mobile uses in their works. We used contextual inquiry interview to understand user's work context and mobile usage. The findings are applied to the service concept, And information architecture, interaction design, GUI design is followed. As a result of design research, Post widget service is designed for instant information organization and functional relationship. And Memory box widget service is designed for business network management and contextual findability. Those services are developed for widget design on touch based phone platform.

Recently, information technology is considered as a basement of management for industries as well as administrations. Especially, government agencies deal with more high sensitive and Important data than other businesses, so, their security managements should be fair and efficient. At present, most government agencies possess and operate their own information security systems, but apply them for the sake of formality only, even do not adapt an audit system for management polices. This paper presents a design and implementation of an automated audit system which is suitable for the operation environment in government agencies, using the audit system based on the BS7799. The. proposed system aims to objectively, numerically and daily control the ISMS (Information Security Management System) for different level of government agencies. In addition, it permits to design and implement an adaptive audit tool, in order to meet a given condition of audit organization and guard the personal relationship between the auditor and its counterpart.

BSC는 전략을 일관되고 통찰력있게 기술하고 전달할 수 있는 체계를 조직에 제공해 준다. 우리가 전략을 기술할 수 없다면, 전략의 실행도 기대할 수 없는 것이다. BSC를 도입하여 획기적인 성과를 창출하는 조직을 말하는 전략 집중형 조직(SFO)에는 아래와 같은 5가지 원칙이 있는 것으로 알려져 있다. 최고경영진의 리더십을 통해 변화를 이끌어내라. 전략을 지속적인 프로세스로 만들어라. 전략을 모든 사람들의 일상업무로 만들어라. 전략의 전사적 정렬을 통해 시너지를 창출하라. 전략을 실천적 용어로 구체화하라. A 기관에서는 '05 년 BSC 도입 전 전략집중 조직진단을 실시하였으며, 1 년의 초기 도입과정 후 '06년 5월 1년간의 과정을 확인해 보기 위하여 다시 전략집중 조직진단을 실시하였으며, 2년간 BSC 실행 후, '08 년초 다시 전략 집중형 조직진단을 실시하였다. 3 년간의 BSC 추진과정을 소개하고, 3 년의 전략집중 조직진단 결과를 중심으로 과연 BSC 추진 조직이 5 가지 영역에서 어떻게 변화되어 가는지를 분석하고자 한다.
