  • Among the firefighting facilities, the fire department connection during firefighting is more important than any other facilities at the firefighting site to supply fire water. This study examined the water supply port of a fire department connection installed at an apartment building based on the Standard for Fire Safety (NFSC 502). The time of discovery was measured by fire fighters who knew or did not know of the water supply port installed in the apartment building, and by separating day and night. To maximize the use of the fire department connection which is the full fire extinguisher facility used by the fire brigade based on the results of the experiment, the author suggests improvement proposals that can clarify the installation location and install the location sign of the fire department connection for the Standard for Fire Safety (NFSC 502).

  • International trade environment is rapidly changing. Developing all economic activities included in the value chain of economy out of a particular country or region in the trends where globalization is spreading all over the world, 'a borderless world' has been created and become common throughout the world. Especially, in case of East Asian region, becoming the factory of the world, China has become a center of the world's economic activities in recent years; and the increase of regional investment among East Asian countries and trade expansion focused on China has been the factor of promoting the formulation of a regional trade network. SCM is an efficient way of adaptation to the complexity or uncertainty on the scene through the achievement of a sustainable competitive advantage by integrating the activities of improving the relationships in the supply chain. In this study, Sumitronics, a Japanese company, was studied as a case of the company who had implemented SCM effectively and efficiently utilizing the East Asian trade network. Not being engaged in the manufacturing processes in the headquarter, Sumitronics has implemented SCM which is capable of maximizing the responsiveness upon the requirements of customers by effective information sharing. In particular, the profits of the company have been maximized through SCM by its headquarter in Japan, which is capable of managing each base in East Asia as China and Southeast Asia, etc. Korean companies may also be able to create a new source of profit by dint of establishing SCM as such. The results of this case study has revealed that the implementation of an effective business model is the key of the successful implementation of SCM.

  • Technological innovation depends on the quality of workers, whose ability is the key component to raise business competitiveness. Our study evaluates how satisfactory is the training of workers at small and medium sized firms, and suggest how to improve upon it. We show the theoretical framework for the relation between customer satisfaction and their behavioral intent on the one side, and factors of training service quality. Our result show: (1) Factors affecting customer satisfaction are, in descending order of importance, expertise, policy, follow-up service, attitude and behavior, and convenience. (2) Contrary to established views on the service quality, satisfaction for training would not be the prerequisite variable for intent to act, in case of training service quality. (3) Satisfaction level for training depends on the type of organization in charge of training (government, university, or private sector.) It also varied among different types of business (L-type, A-type, and J-type.) Small and medium sized firms find it difficult to commit to training education due to lack of money and manpower. The recent expansion of free training service would address part of this problem. On the other hand, the outfit in charge of training could boost service quality by customizing their training program to the type of business they cater to.

  • Methodist church materials are classified with three types, centered on the organizations manufacturing and holding materials such as 1) 'materials of the Methodist headquarter' governing all of the Methodist churches in Korea, 2) 'materials of theological seminary libraries' holding academic study books related to theology, and 3) 'materials manufactured in individual churches'. In this manner, the Methodist church materials imply homogeneity in theme, but the materials have identity from each other, because organizations are different each other, too. By a characteristic of each organizations, to use Methodist church document done a director of each organization is demanded collaboration between the material departments of each organizations, this study intends to analysis material department operation status of three Methodist church organizations. As a result of analysis, it is necessary to perform the prior tasks, such as reconstructing organization to accomplish an original function of the Methodist headquarter, developing operation regulation classified with the Methodist church group, and constructing material management system.

  • The environmental ecological flow (EEF) of stream or river will be designated according to the enforcement of the Water Environment Preservation Act. Previous researches by Ministry of Environment have proposed agricultural reservoirs as alternative resources to secure river flow where multi-purpose dam does not exist. However, agricultural reservoirs are constructed for the supply of agricultural water, and in fact, there is not a sufficient amount of water to be supplied to rivers as EEF. Therefore, this study examines the economic feasibility of securing EEF through the remodeling or construction of agricultural reservoirs. We investigated water balance of reservoir through simulation of three types of water supply demands such as agricultural water, agricultural water and river maintenance flow, and agricultural water and environmental ecology flow. The economics analysis was conducted on water supply demands and corresponding remodeling or construction of reservoirs. As a result, it was found that the method of securing through heightening existing reservoir enhancement is economically feasible. However, it was not possible to secure all the amount of the EEF due to the size limitation of existing reservoirs or constrain of the watershed for newly built reservoir. Therefore, in order to secure all of the EEF, the utilization of other alternatives as well as agricultural reservoirs should be considered. This study demonstrated the method of economical feasibility study of securing river maintenace flow and EEF using agricultural reservoirs and other considerations.

  • Objectives: The purpose of this study is to suggest a direction for consumer-oriented curriculum development by analyzing the priorities of subjects and their preference for educational methods. Methods: The participants included 773 management supervisors and education practitioners in the workplace, and a survey was conducted from April 17 to August 30, 2019. Frequency analysis, t-test, Borich's Needs Analysis, and Locus for Focus Model analysis were performed using Microsoft Excel 2019 and IBM SPSS 21.0. Results: The highest perceived priorities for education subjects were as follows: ① 'CPR and First Aid Practice' and 'Occupational Disaster Prevention and First Aid Basics' in the manufacturing industry; and ② 'Emotional Labor and Job Stress Prevention', 'Occupational Disaster Prevention and First Aid basics, and 'Musculoskeletal Disorder Prevention' in the service industry. 'Collective education' was the most preferred method of education. 'School-type' was preferred for the seating arrangement, and the proper number of trainees was considered to be about 30. Respondents said the contents of the education was a top priority when they applied for education, and curriculum and appropriate textbooks should be considered in calculating the cost of education. Conclusions: Practical subjects and subjects related to major hazards by industry were required for management supervisor education. It was proposed in this study that the contents and operating methods of education be changed so that workers can easily comprehend essential subjects such as the Occupational Safety and Health Act. In conclusion, it is necessary to design the curriculum and apply educational methods suitable for each subject's characteristics in consideration of the priorities for subjects reflected in the needs of trainees.

  • Despite the practical limitations of calculating the amount of inflow and supply related to the operation of agricultural reservoirs, the role of agricultural reservoirs is gradually being emphasized. In particular, as interest in disaster safety has increased, the demand for preliminary measures to prepare for disasters has been rising, for instance, pre-discharging agricultural reservoirs for flood control. The aim of this study is to analyze the plans for the flood season reservoir operation considering pre-discharge period and water level limit. Accordingly, we optimized the simulation of daily storage using the ratio correction factor (RCFs) and analyzed the amount of inflow and supply using K-HAS. In addition we developed the drought determination coefficient (k) as a indicator of water availability and applied it for supplementing the risk level criteria in the Drought Crisis Response Manual. The results showed that it would be difficult to set the water level limit during the flood period in the situation of little water supply for flood control in agricultural reservoirs. Therefore, it is necessary to operate the reservoir management regulations after measures such as securing additional storage water are established in the future.

  • This study established a water supply network based on the operation case of Mandae Reservoir in Yanggu-gun, Gangwon-do, to analyze the efficient distribution and management of agricultural water supplied from the reservoir to irrigation areas using the hydraulic analysis model SWMM. In order to construct a model to analyze the water canal network, network conditions needs to be simplified, and in particular, excessive detail or simplification of the irrigation area can lead to errors in the analysis results. Therefore, the effect of the water canal network model was analyzed by simulating the appropriate simplification process step by step. The results of simplifying the actual block shape of the analysis target area using SWMM showed that there was no significant difference in the results even if 7 lots were simplified to 2. Also, it was found that the construction and analysis of a simplified network model were reliable when the excess quantity was 2% or more compared to the required quantity for each case of analysis of the paddy field.

  • Previous scholars have studied Daesoon Jinrihoe mainly through its scriptures and doctrines; however, in this essay I have combined data from a questionnaire with interviews I conducted to observe women's religious engagement from their own perspectives. I conducted my fieldwork from October 23 to 26 at Yeoju Headquarters in Korea and received 81 questionnaire replies. This ongoing project will shed light on the niche for women in Korean new religious movements. This essay is divided into three parts. First, I reviewed 5 articles on general attitudes towards women within Daesoon Jinrihoe to serve as a doctrinal introduction. Second, I used the Ladies Club, the Women's Assembly of the Department of Social Welfare, and female students from the Inter- national Volunteers Association to better understand women's participation and education in Daesoon Jinrihoe on an institutional level. Third, I issued a questionnaire in order to learn respondents' sex, age, educational background, and birth place and used those data points determine patterns in how the above influence religious participation and positions in Daesoon Jinrihoe. My investigation showed that both the self-expectation and division of labor among the followers at Yeoju Headquarter were affected by and corresponded to social gender roles. Moreover, the emphasis on missionary work rather than centralized hierarchy contributed to a reduction in the influence of gender-segregation and led to relative coherence in terms of gender relations within Daesoon Jinrihoe.

  • Optimal water management is to efficiently and equally supply an appropriate amount of water by using irrigation facilities. Therefore, it is necessary to evaluate water supply capacity through distribution simulation between the designed distribution rate and re-distributed rate according to the changed farming conditions. In this study, we recalculated the agricultural water supply amount of Geumcheon main canal, which beneficiary area was reduced due to the development of Gwangju-Jeonnam innovation city, and we constructed a canal network using the SWMM model to simulate the change in supply rate of each main canal according to the re-distributed rate. Even though the supply amount of the Geumcheon main canal was reduced from 1.20 m3/s to 0.90 m3/s, it showed a similar supply rate to the current, and the reduced quantity could be supplied to the rest of the main canal. As a result, the arrival time at the ends of all main canal, except for the Geumcheon main canal, decreased from 1 to 3 hours, and the supply rate increased from 4 to 17.0% at the main canal located at the end of the beneficiary area of Naju reservoir.
