현재 사용되고 정보 서비스 기술의 형태는 다양화, 복잡화되고 있지만 대부분 웹 기반 서비스 기술을 사용하고 있다. 그러나 이러한 기술은 분산되어 있는 정보를 가공하는 과정이 복잡하고, 검색결과가 너무 많아 정보의 질이 저하된다. 또한, 한정적인 대역폭으로 인해 네트워크 상에 지연문제가 발생하여 효율적인 정보를 사용자에게 전달하지 못한다. 따라서 본 논문에서는 멀티 에이전트 기반의 Web/Mobile 환경에서의 능동적 정보 서비스를 위한 시스템을 구현한다. 제안된 멀티 에이전트시스템에서는 기존의 웹 기반 정보 서비스가 가진 단점들을 해결하기 위해서 이동 에이전트의 작업 실행 모듈을 분리하는 CORBA 기반의 이동에이전트를 구현하여 분산된 다양한 정보를 효과적으로 수집하였고, 네이밍 에이전트의 호스트 이주를 위해 노드의 위치 투명성 및 최초 라우팅 스케줄을 지정하는 네이밍 에이전트를 구현하였다. 마지막으로 사용자에게 지속적인 정보 서비스를 제공함으로 네트워크 트래픽을 가중시키는 문제를 해결하였다.

The purpose of this research is to prepare the measures for evaluating the job of horse-riding instructor and improvement related to it and for distributing horse-riding industry effectively. Forsuch, we tried to analyze job of horse-riding instructor. Inparticular, we have developed DACUM chart of horse-riding instructor through DACUM method and experts related to it. As result, we found out eight duties and hundreds of job and arranged seven duty areas in total and eighty-two executed works. In addition, as experts said, the horse-riding instructor is the one who 'instructs people learning horse-riding in horse-riding facility and manages horses, horse-riding equipment and man-power.' Such results provide the procedure of horse-riding instructor cultivation which has been presently underway with many viewpoints. Especially, there are three educational processes and subject materials related to horse-riding instructor's examination(Hipologia, Horse-treatment technique, Horse Health management). However, as result of analysis on duty, we found out that racecourse management and horse-riding education theory has been needed to be added and complemented as well. In addition, the work and duty of analysis can be used to be made use up of as work profile and specification and such data can be also made use of as standard of training and submission. Through this study there should be a necessary work to distinguish between re-drafting and role of duty in its own right related to certification of horse-riding instructor in future and it would be necessary to develop study that is able to connect them all to certificate. What is more, there should be work and measure required for rethinking of utility of certification.

Purpose: This study was to explore situations that might put the middle-aged Korean-Chinese female migrant workers at risk for work-related musculoskeletal diseases (WMSDs). At the development phase of a continuing health project, the study aimed to clarify health promotion program needs of the migrant population. Methods: A qualitative description research design was used with three focus groups of 23 Korean-Chinese female migrant workers. Each focus group interview was conducted for 70-minutes using semi-structured interview guidelines. The data were analyzed using directed qualitative content analysis techniques. Results: The majority of the participants were household workers and their work included heavy material handling, standing for a long time, and working in awkward postures. They experienced discrimination from employers, lack of control at work, limitations in open-communication, job insecurity, and acculturation. They had needs to have health promotion programs for preventing and managing chronic diseases, depression and menopause as well as WMSDs. Conclusion: The participants were situated in work environments with physical demanding tasks, acculturative and job-related stress and lack of opportunities to participate in health promotion programs. It is suggested to develop a comprehensive program to better meet the needs of middle-aged Korean-Chinese female migrant workers rather than targeting the reduction of WMSDs.

This paper presents a scheduling technique that reflects various constraints in remodeling project of inhabited condition. The remodeling project of inhabited condition is required more detailed planning and control due to claims by noise, vibration, dust, smells, limited lift capacity, and limited temporary stock area. Because of the constraints, complexity in scheduling is increased and earlier completion is required to reduce the possibility of safety and environment accidents. Especially, in case of inhabited condition, the scheduling should be linked day-time/night-time/weekend work. This paper proposes a structured scheduling technique to incorporate those constraints in remodeling of inhabited condition. This scheduling technique considers not only remodeling process but also dismantling, newly-construction, and residents movement. Process expression method using MS-Project also presented to keep connectivity with existing scheduling system.

With the development of the internet technology, network application services based on a large number of network nodes have been focused. However, such application services require much larger network size and traffic than current network. In order to develop them, efficient solutions as well as a simple improvement of network infra processing time are required. In this paper, to contribute a improvement of network computing technology, we design and implement the agent platform software based on the agent technology that performs works independently and asynchronously on a network and platform. The proposed agent platform software supports the scalability to accommodate the number of network hosts with rapid growth, the adaptability on a variable environments, and the availability for a fault-tolerance.

The purpose of this study was to compare radiation dose among workers in the radiation zone and to compare the doses of students in clinical practice in the same area to provide basic data on optimization of radiation protection. The subjects were 121 radiation related workers, 36 radiation workers, and 121 students who completed 8 weeks of clinical practice from Jan. 2016 to Dec. The depth and surface dose between the radiation related workers and the radiation workers were the highest with $.7440{\pm}1.676mSv$ and $.7753{\pm}1.730mSv$, respectively, and statistically significant (p<.01). Among the three groups, the depth dose was the highest at $.143{\pm}.136mSv$ for clinical practice students and the highest at surface dose of $.1513{\pm}.139mSv$. The lowest in both cases, The mean difference between the two groups was statistically significant (p<.01). In conclusion, it is necessary to manage thoroughly according to the ALARA(As Low As Reasonably Achievable) principle. Especially, it is necessary to systematically manage the dose of radiation for clinical students who are in the blind spot of radiation safety management.

This study aims to improve the safety inspection awareness of occupational exposure and help radiation safety management by analyzing radiation exposure doses by occupational type of radiation related-workers and radiation workers. Radiation-related workers and radiation workers were classified into three occupations (radiological technologist, doctors, and nurses). A nominal risk coefficient based on ICRP 103 was used to calculate the probability of causing side effects of the lungs due to exposure doses. As a result of analyzing the exposure dose of all workers for one year, the exposure dose of radiological technologist among radiation-related workers was 1.63 ± 2.84 mSv, doctors 0.12 ± 0.22 mSv, and nurses 0.59 ± 1.08 mSv. The one-year deep dose for radiation workers was 2.44 ± 3.30 mSv for radiological technologists, 0.19 ± 0.26 mSv for doctors, and 0.12 ± 0.00 mSv for nurses. Due to this dose, the probability of causing side effects in the lungs was 1.2 per 100,000 radiological technologist, 0.096 doctors, and 0.06 nurses. In this study, it is believed that the probability of side effects on lungs by occupation of radiation exposure dose will be studied and used as useful data for radiation safety management in relation to probabilistic effects in the future.
