This study aims to analyze ordinance in a local government for the improvement of the preferential purchasing system of products manufactured by disabled. So, This study analyze 44 ordinance of a local government. The results of this study were as follows. First, 44 local governments enacted the ordinance(rate was 18.1%). Second, Most of the local governments suggest purpose of ordinance, agency of application, establishment of support plan, request of purchase cooperation, duty of purchase promotion. But there are not suggest other items in many ordinance. In particular, Duty of local government president is specified only 30(rate was 68.1%). Third, The municipal ordinance conflicting with the upper laws and regulation. Forth, The Council for the promotion of the preferntial purchasing system of products made by disabled upgrade to an advisory organization including professor, expert, disabled. Fifth, The sales routes of products need to be extended from the public agency to private companies for Preferential purchasing in affirmative action. In order that the Preferential purchasing system will not be a nominal law, the government should show active willingness about monitoring of local government.

This study was aimed at analyzing the operational efficiency of DPAs(the delivery and pickup agents), which serve as sub-terminals in parcel delivery services, using CCR/BCC models in DEA. The input variables included the number of employees, and the amount of equipment and the operating expenses. The output variable was revenue value. The efficiency for the period from 2014 to 2016 was analyzed. The results revealed that the operational efficiency improved in 2016, compared with 2014, in both CCR and BCC models. According to the benchmarking analysis, DMU 1 and DMU 7 showed higher efficiency in 2016. The inefficiency analysis based on the BCC model showed increased efficiency of all factors in 2016 when compared with 2014. The Malmquist productivity index (MPI) dropped slightly as a result of technical changes and indicated a declining technical efficiency in all DMUs. This study suggests the need for government-led systematic improvement and support for DPAs by providing current insight into the parcel delivery industry and analyzing DPAs' operational efficiency in Korea for the first time. This research performed efficiency analysis of DPAs located in new town of paju and gimpo cities. In future research, comparative study on efficiency analysis including new town, old town area, and other cities are needed.

This study was designed to examine Home Nursing Care in Hospital-based and Community-based programs. This study investigates actual conditions of nursing needs and demands of clients and their family and the state of home nursing services. We hope that this study will improve upon the current home nursing care system. In Korea Home-Nursing Care programs are still developing and only now becoming a part of the health care delivery system. The data was collected by a questionaire the clients developed and modified through literature review by this writer and through 10 nurses who are members of 4 hospital and 3 community- based agencies. In this study 173 clients were selected. The study lasted from Oct. 1997 to March of 1998. The results show that the average age was 64.3, years older than most women clients (63.0%), the average age of a caregiver was 50.9 years old and most were female(77%). Two types of agency clients with a significant difference between social conditions [25.7%] used some form of insurance; 54.3% had the spouse pay expenses; pay 58.5% son and daughters of Hospital-based agencies: patients of social workers were 24.0%, the highest in the community agency. The condition of patients was 63.2% of the foley and nelaton catheter insertion at hospital based agencies. The range of nursing services offered is one of the highest among the 34 kinds of servies including nasogastric tube management basic nursing, ROM exercise, bladder irrigation, wound and sore dressing. For an effective care service factors that disturb each program such as a non-cooperatative family as well as patients themselves need to be lessened. Further more, the following must be emphasized, supportive counsel 27.0%, steady care for patient, 13.3%maintain a sense of security(11.7%), dressing sores and nutrition(10.0%). Although there were a large number of home nursing care services in the community, policy changes have gathered momentum. Fortunately, the scope and level at legal support will be increased in the future. The program should intergrate and link the district or community together. A project to develop a community based home nursing system as soon as possible should be developed. In conclusion, home nursing care nurses training curriculum should be strengthened.

The existing effective path-length model of ITU-R has some drawbacks: The prediction error is quite large compared to domestic measurement data and it is an empirical model in which the physical characteristics of rain cells are not considered. In this paper, a theoretical model for effective path-length using the rain-cell concept was proposed and its validity was verified using the measurement data. To analyze the statistical characteristics of rain cell parameters, the weather-radar data(CAPPI) measured by Korea Meterological Administration were analyzed and the correction factor was properly introduced to fit the Chollian beacon measurement data of ETRI(Electronics and Telecommunications Research Institute). To verify the proposed effective path-length model, it was compared with the Mugunghwa No. 5 beacon data measured in Chungnam National University with the support of ADD(Agency for Defense Development). It was confirmed that the prediction results of the proposed model are in good agreement with the measurement data.

The purpose of this study was to analyze the characteristics reflected in the 2015 revised home economics curriculum for the key competencies presented in the OECD education 2030 project. The results indicate that first, in general, about 46.5% of the competencies could be classified into the skill, attitude and value category; 17% into the learning concept framework category; 24.2% into the competency development cycle category; and 12.5% into the complex competency category. Overall, the competencies of the OECD learning framework are found to be reflected primarily in the achievement standards(59%), followed by characteristics(16.1%), teaching-learning and assessments orientation(9.4%), content system(8%), and goals(7.6%). Second, the key competencies were reflected in the middle school curriculum, more often in the descending order of action, problem-solving, communication, respect, creative thinking, conflict resolution, empathy, critical thinking, self-regulation, and student agency. In the high school curriculum, the competencies were reflected more often in the descending order of action, empathy, problem-solving, anticipation, global competence, self-regulation, student agency, literacy for sustainable development, reflection, and critical thinking. Third, the heat map shows that the competencies corresponding to the third and fourth levels are most frequently reflected in the curriculum. Therefore, it is advisable to develop effective plans to execute and support the reflection of key competencies in the curriculum. Through this study, home economics educators are expected to understand the inter-connectivity between the key competencies emphasized by the OECD learning framework and the competencies of home economics as a practical subject, and to scrutinize how to help individual students develop their overall competencies and be prepared for the future.

Recently EA(Enterprise Architecture) has been receiving growing attentions again from the public sectors. It is because EA maturity result is reflected to the organization's informatization level and EA maturity ratio has been enlarged. There has been more participation from the Chief Information Officers of the public sectors. EA research in the public sectors has influenced IT environment since the research started in late '90, the legislation work done in '05, and the maturity model developed in '06. However, there are some remaining tasks to solve. EA policy is introduction oriented, its contribution to the consecutive the best UN e-Government rank is limited, and its user-friendly responding system is still lacking. Related research outcomes are rather microscopic focusing only on the models and maturity than implicating on the public policy in a macroscopic manner. In this respect, this study will provide the implication on how EA policy should be. Requirements derived from EA stakeholders and the tasks will be arranged in accordance with its domain, then the performance and tasks will be demonstrated. As guiding EA stake holders and information related officers to setup the EA policy with these results, this study is expected to support information the policy drivers.

To solve the problem of frequent component failure in guided weapons, a process of component failure in developed countries was investigated and analyzed. The suitability of component control, including risk assessment, analysis of operational impact, and the establishment of response measures, was also demonstrated. In addition, the economic effects of component control were presented by estimating the costs incurred if component control is performed in advance, after-sales, and non-management. DMSMS problems refer to losses or impending losses of an item, raw material, or software manufacturer or supplier. A problem with the discontinuation of parts occurs when the manufacturer or supplier ceases to produce and support the necessary parts, materials, or software, or when the supply of raw materials is no longer possible. Hence, it is important to recognize that failure to all parts of the system can occur.

Major corporations and portals have implemented a link server that connects Content Management Systems (CMS) to the physical address of content in a database (DB) to support efficient content use in web-based environments. In particular, a link server automatically connects the physical address of content in a DB to the content URL shown through a web browser screen, and re-connects the URL and the physical address when either is modified. In recent years, the number of users of digital content over the web has increased significantly because of the advent of the Big Data environment, which has also increased the number of link validity checks that should be performed in a CMS and a link server. If the link validity check is performed through an existing URL-based sequential method instead of petabyte or even etabyte environments, the identification rate of dead links decreases because of the degradation of validity check performance; moreover, frequent link checks add a large amount of workload to the DB. Hence, this study is aimed at providing a link server that can recognize URL link deletion or addition through analysis on the B-tree-based Information Identifier count per interval based on a large amount of URLs in order to resolve the existing problems. Through this study, the dead link check that is faster and adds lower loads than the existing method can be performed.

Natural magnetic fields are attenuated by electrically conductive water. For that reason, marine magnetotelluric surveys have collected data at long periods (1000-100 000 s). The mantle structure has been the main target of seafloor magnetotelluric measurements. To ascertain crustal structure, however, electromagnetic data at shorter periods are important, e.g. in investigations of megathrust earthquake zones, or in natural resource surveys. To investigate of the former, for example, electromagnetic data for periods of less than 1000 s are necessary. Because no suitable ocean bottom electromagnetometer (OBEM) has been available, we have developed a small OBEM and ocean bottom electrometer (OBE) system with a high sample rate, which has an arm-folding mechanism to facilitate assembly and recovering operations. For magnetic observation, we used a fluxgate sensor. Field observations were undertaken to evaluate the field performance of our instruments. All instruments were recovered and their electromagnetic data were obtained. Results of the first experiment show that our system functioned well throughout operations and observations. Results of other field experiments off Tottori support the claim that the electromagnetic data obtained using the new OBEM and OBE system are of sufficient quality for the survey target. These results suggest that this device removes all instrumental obstacles to measurement of electromagnetic fields on the seafloor.

The purpose of this research is to empirically examine the effects of motivation and skill for digital devices and the Internet on the use of online services in the severely disabled people. In addition to the general effect of digital divide, particularly for the case of severely disabled people, the effects of physical and mental inconvenience of individuals were taken into account and the moderating effect was confirmed by classifying the groups that need help with online activities and those that do not. The 2018 Digital Divide Survey data of the National Information Society Agency was used for the study. As a research method, path analysis and multi-group analysis using a sequence access model to Internet use were performed. As a result, it was confirmed that even in the case of the disabled, the motivational factor affects the skill for digital device operation and Internet use, and this access skill sequentially affects the use of online services. In particular, it was found that the effect of strategic and technical skill for internet use is the most important for the use of online services for the disabled rather than the motivation or a simple operational skill for digital devices. In addition, it was found that even in the disabled group, those requiring help in using the Internet was more passive in using the online service than the rest in the group. The results of this study suggest the need for stronger capacity for physical access as well as support in building strategic and technical skills that enhance responsibilities and protect from risks in using the Internet among the people with disabilities.
