최근기업의 경쟁력 확보를 위해 기업내의 분산된 이질적인 정보 시스템을 전사적차원에서 통합을 하려는 노력이 활발히 진행되고 있다. 그 중 많은 경우에 통합 문제를 향후의 IT환경을 고려하여 객체지향 개념의 JAVA 및 CORBA를 기반으로 해결하려고 하고 있다. 하지만 실제 기업 환경에서 적용된 경우는 아직 드물다. 본 논문에서는 바이어가 전자회사에 주문한 물품의 생산 현황, 출하까지의 예상시간, 배송일 등을 실시간으로 확인할 수 있는 시스템인 주문 물품 모니터링 시스템(DW- GOMS: DasWoo -Global Ordering status Monitoring System)의 구현에 대해 설명한다. 이 시스템에 대한 사용자의 요구사항 분석은 Use Case를 이용했고 분석 및 설계는 OMT 프로세스를 도입하였고 그 결과는 UML로 표기하는 등 객체지향 개발 방법론을 적용했으며, 설계된 결과를 바탕으로 JAVA 및 CORBA를 기반으로 구현하였다. 구현된 시스템은 CORBA를 적용하여 개발 속도를 현저히 줄일 수 있으며, 시스템 분석/설계에 객체지향 개발 방법론을 적용함으로써 향후 시스템 변경에 유연하게 대응할 수 있게 된다.

Purpose: The purpose of this study was to examine factors influencing new graduate nurse turnover. Methods: This study was carried out as a secondary analysis of data from the 2010 Graduates Occupational Mobility Survey (GOMS). A total of 323 nurses were selected for analysis concerning reasons for turnover. Data were analyzed using descriptive statistics and multilevel survival analysis. Results: About 24.5% of new nurses left their first job within 1 year of starting their jobs. Significant predictors of turnover among new nurse were job status, monthly income, job satisfaction, the number of hospitals in region, and the number of nurses per 100 beds. Conclusion: New graduate nurses are vulnerable to turnover. In order to achieve the best health of the nation, policy approaches and further studies regarding reducing new graduate nurse turnover are needed.

정보통신기술의 발달과 WWW 의 출현으로 인터넷 기반 가상 상점이 점차 보편화, 일반화 되어 가고 있다. 그러나 가상 상점이 보다 활성화되기 위하여서는 해결해야할 문제점을 많이 안고 있는데, 특히 사용성 문제는 가상 상점의 활성화를 저해하는 주요 요인중 하나로 인식되고 있다. 그렇지만 가상상점의 사용성을 평가하고 보다 개선된 대안을 제시할 수 있는 과학적이며 구체적인 방법에 관한 연구는 아직 많지 않은 실정이다. 이에 본 연구에서는 가상상점의 접속, 상품검색,구매절차 과정의 사용성을 분석할 수 있는 구체적이며 실용적인 분석 절차를 개발하여 제시하며, 또한 이 방법론을 실제 가상 상점의 분석에 적용하여 본 연구가 제시하는 방법론의 실효성을 검증한다. 본 연구에서 개발한 분석 방법은 HCI 분야에서 개발된 GOMS 방법론을 기반으로 하여 이를 가상상점의 분석에 적합하도록 발전시킨 형태이다.

Using the data of Economically Active Population Survey and GOMS, we analyze youth employee's labor mobility. We found the causes of the youth employee's labor mobility as follows: work environment, salary, enterprise's vision, job satisfaction, job mismatching, organizational culture, mismatching of work and housing and so on. On the basis of results, we proposed a step by step solutions. The resulting policy implication is that rather than raising job finding rate of the unemployed youths, we need to focus more on reducing job mismatching.

The central monitoring system with on-line diagnosis of high-voltage generator/motor stator insulation is developed. The system is capable of remote diagnosis and monitoring partial discharges of high-voltage generator/motor stator insulation. GOMS(Generator On-line Monitoring System) with maximum of 9 input channels can measure and analyze the status of high-voltage motor stator insulation by on-line. The measured and analysis data are brought to the central monitoring system via modem to build database. The central monitoring system can diagnose and monitor the insulation status of several high-voltage generator/motor at any time. The insulation status of those machines can be enhanced by the database on partial discharges.

NURBS surfaces have been widely used in engineering design since it can create a smooth surface using minimal numbers of data. But deformation of the surfaces is quite difficult especially for the detailed modification. Also, NURBS surface deformation processes need many inputs, and it is not easy to be implemented in 3D virtual system. In this paper, both the surface trimming and multi-resolution surface are used for the detailed sculpting including sharp edges of NURBS surface. QuadTree is used to separate cleanly the target surface with the surface for sculpting effect. Simple user strokes are also used for the sculpting target curves and GOMS(Goals, Operators, Methods, Selection Rules) model is applied to verify the efficiency of the proposed sculpting process.

The current study examines principles to develop universal design guidelines for manufacturing information and communication devices. The study surveyed inconveniences disabled people experience in the information and communication environment with current technology and design, and suggested abbreviated universal design guidelines. Design guidelines should reduce those inconveniences detected through the task analysis and GOMS modelling of the usage by disabled people. Design and functional features of mobile phones were examined since they quickly became essential communication tools for both disabled and non-disabled people alike. Design issues were examined in controls, input methods, and output methods in terms of human factors and ergonomics. It is expected that both governments and manufacturers can save costs to produce and manufacture special assistive devices for disabled people by implementing universal design in their communication products. Since it is becoming the international trend, application of the universal design should be enforced to all communication and information devices by government for the higher quality of life for all groups of user.

Each year research institutions such as the Korea Employment Information Service(KEIS), a government institution established for the advancement of employment support services, and Job Korea, a popular Korean job website, announce first job waiting times after college graduation. This provides useful information understand and resolve youth unemployment problems. However, previous reports deal with the time as a completely observed one and are not appropriate. This paper proposes a new study on first job waiting times after college graduation set to 4 months prior to graduation. In Korea, most college students hunt for jobs before college graduation in addition, the full-fledged job markets also open before graduation. In this case the exact waiting time of college graduates can be right-censored. We apply a Cox proportional hazards model to evaluate the associations between first job waiting times and risk factors. A real example is based on the 2008 Graduates Occupational Mobility Survey(GOMS).

This study analyzed the employment efficiency of Korean colleges and universities using DEA(2015 GOMS), which was surveyed by the Ministry of Employment and Labor and the Korea Employment Information Service. The input variables were employment program participants, language educators, family economic applicants, and employment targets. As a result, the college was more efficient than the college and the college was relatively ineffective. The contribution of input and output contributed the highest efficiency with 99.9% of the participants in the employment program, and the possibility of improving the efficiency of the language educator was the highest at 70.04. Based on the results of the above research, it suggests the necessity of activation of employment programs and activation of language training in each university. Future studies will need to study the efficiency of universities nationwide.

The employment rate of university graduates has been decreasing significantly recently. With the advent of the Fourth Industrial Revolution, the demand for software employment has increased. It is necessary to analyze the factors for software employment of university graduates. This paper proposes explainable software employment model of university graduates using machine learning and explainable AI. The Graduates Occupational Mobility Survey(GOMS) provided by the Korea Employment Information Service is used. The employment model uses boosting machine learning. Then, performance evaluation is performed with four algorithms of boosting model. Moreover, it explains the factors affecting the employment using SHAP. The results indicates that the top 3 factors are major, employment goal setting semester, and vocational education and training.
