Several environmental problems have occurred and extremely affected throughout the East Asia region. Satellite imageries and spatial information have been used in the applications of environmental and natural hazard management for years. Sharing these data and resources in the community is considered as one of the optimal solution. It would consequently bring cost saving to all participated countries and eventually be beneficial to mankind as a whole. Encouraged by these factors, ASEAN＋3 Satellite Image Archive for Environmental Study project was submitted by Thailand in the 3rd Senior Official Meeting between ASEAN, China, Japan and Korea (SEOM＋3 Meeting) and approved by the SEOM＋3. The main objectives of this project are to share satellite images, information related to natural resources and environmental issues, and to provide data information services to all ASEAN＋3 countries. The proposed system is basically embedded by distributed system. The network of data users, data providers, and the center will be established using the Internet. User can access, navigate, display, and even download some archived contents. Its service site can be generally categorized into two parts, which are environmental related data archive and the Integrated satellite image catalogue. The extension of web based GIS is also planned for future development so that GIS users can conduct some preliminary analysis directly on line. This presentation will indicate scope of work, system, working scenario, and work plan of the project.

This article presents a new design of earthquake instrumentation that is suitable for quick decision-making after the seismic event at the nuclear power plant (NPP). The main objective of this work is to ensure more availability of the NPP by expediting walk-down period when the seismic wave is incident. In general, the decision-making to restart the NPP after the seismic event requires more than 1 month if an earthquake exceeds operating basis earthquake level. It affects to the plant availability significantly. Unnecessary shutdown can be skipped through quick assessments of operating basis earthquake, safe shutdown earthquake events, and damage status to structure, system, and components. Multidecision parameters such as cumulative absolute velocity, peak ground acceleration, Modified Mercalli Intensity Scale, floor response spectrum, and cumulative fatigue are discussed. The implementation scope on the field-programmable gate array platform of this work is limited to cumulative absolute velocity, peak ground acceleration, and Modified Mercalli Intensity. It can ensure better availability of the plant through integrated decision-making process by automatic assessment of NPP structure, system, and components.

Workplace violence (WPV) is an increasing cause of concern around the globe, and healthcare organizations are no exception. Nurses may be subject to all kinds of workplace violence due to their frontline position in healthcare settings. The purpose of this systematic review is to identify and consider different interventions that aim to decrease the magnitude/prevalence of workplace violence against nurses. The standard method by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA, 2009) has been used to collect data and assess methodological quality. Altogether, twenty-six studies are included in the review. The intervention procedures they report on can be grouped into three categories: stand-alone trainings designed to educate nurses; more structured education programs, which are broader in scope and often include opportunities to practice skills learned during the program; multicomponent interventions, which often include organizational changes, such as the introduction of workplace violence reporting systems, in addition to workplace violence training for nurses. By comparing the findings, a clear picture emerges; while standalone training and structured education programs can have a positive impact, the impact is unfortunately limited. In order to effectively combat workplace violence against nurses, healthcare organizations must implement multicomponent interventions, ideally involving all stakeholders.

This study suggests ways to strengthen the expertise by analyzing the problems caused by the lack of expertise of the qualification management body managing the Korean qualifications in the realm of firefighting from the perspective of external signal dependency of capture theory. As a method to prevent the dependency of external signals in capture theory, it is suggested to strengthen the expertise of regulators and strengthening roles and functions of regulator institutions by supplementing education and professional manpower. On this basis, analyzing the problems of qualifications management to the external signal dependency tendency, the researchers in qualification management at the Human Resources Development Service of Korea have a variety of different majors, so understanding and application can be limited if they are working in an unfamiliar area of work. Therefore, in making decisions regarding topics such as policies and roles, suitable alternatives should be found based on external signals. In order to improve this, it is necessary to select firefighting majors in the Korean qualification management of the firefighting realm, to reorganize the job scope to a similar job field of the researcher in charge. It is also necessary to strengthen the expertise of the researcher through various programs, such as mandatory periodic maintenance education in order to understand the work of the researcher.

In a rapidly changing environment, it is essential for companies to develop their capabilities for sustainable growth. To this end, informal learning at work plays an important role for small and medium-sized enterprises that are having difficulties in human resource development. If the GRIT of workers and the spiritual leadership of leaders are maintained at an appropriate level, the effect of informal learning will increase. This study derived the following results through a survey of workers participating in the Work-learning Dual System in Korea. First, experience and feedback among informal learning activities have a significant positive effect on competency development. Second, the higher the level of the GRIT of workers, the greater the magnitude of the positive effect of experience and feedback on competency development, showing a positive moderating effect. Third, in the case of workers with high GRIT, capacity development is strengthened as experience or feedback increases, and the higher the level of spiritual leadership, the greater the scope of reinforcement. On the other hand, it can be seen that in the case of workers with low GRIT, competency development weakens as experience or feedback increases, and the higher the level of spiritual leadership, the greater the extent of the weakening.

The "information roadway" will give us an impact of new PC based assignments and administrations, yet the unusualness of this new condition will ask for another style of human-PC association, where the PC transforms into a sharp, dynamic and customized partner. Interface administrators are PC programs that use Artificial Intelligence frameworks to give dynamic help to a customer with PC based errands. Operators drastically change the present client encounter, through the similitude that a specialist can go about as an individual collaborator. The operator procures its capability by gaining from the client and from specialists helping different clients. A couple of model administrators have been gathered using this methodology, including authorities that give customized help with meeting planning, electronic mail taking care of, Smart Personal Assistant and choice of diversion. Operators help clients in a scope of various ways: they perform assignments for the client's sake; they can prepare or educate the client, they enable diverse clients to work together and they screen occasions and methods.

첨단장비 도입 및 기술의 발전으로 수문조사 측정 기술은 향상되었으나 여전히 수문조사 시 많은 인력과 시간이 필요하며, 업무 규모와 범위에 비해 투입되는 인력은 매우 제한적이다. 또한, 자동유량 측정시설이 운영되고 있지만 현장 조건의 제한되기 때문에 전국으로 확대하기가 어렵다. 따라서 수문조사를 위해 측정 기술 자체보다는 운영 인프라 및 환경 개선이 필요하다. 또한 유량조사 측면에서 수위-유량 관계식의 정확도 재고와 업무 효율성 증진을 위해 실시간 수위 정보를 이용한 조사 스케줄링이 필요하다. 따라서 본 논문에서는 국내 수문조사 관련 연구 파악 및 수문조사의 경제성과 효율성 증대를 위하여 Open API 기반의 실시간 수위 정보를 활용한 수문조사 스케줄링 시스템을 구현하였다.

Purpose: The purpose of this study was to describe the job performance, importance, and difficulty in Surgical Clinical Practice Nurses (SCPNs), and to identify the priority of job tasks using Importance-Performance Analysis (IPA). Methods: One hundred SCPNs were recruited from two university hospitals and two general hospitals during November 2021 to April 2022. A total of 97 data were analyzed excluding 3 data due to missing responses. The data were analyzed by two groups, with Ward-Based SCPNs (W-SCPNs) and Operation Room-Based SCPNs (OR-SCPNs) according to different characteristics of job tasks. Results: There were differences of job performance between W-SCPNs and OR-SCPNs. As a result of the IPA, tasks of 'working practices in the ward' for W-SCPNs and those of 'surgery and treatments' for OR-SCPNs were included in the first quadrant (keep up the good work). 'Resarch' and 'leardership' were included in the third quadrant (low priority). Conclusion: Since there are differences in job tasks between W-SCPNs and OR-SCPNs, health care institutions should consider the differences in defining the scope of job performance. Furthermore, it is necessary to develop customized continuing education program based on our findings of IPA.
