  • Polymer cement mortar which is used as material for aging concrete structures is generally mixed manually and applied on the job site. but, to secure the required quality of the mortar, pre-mixed polymer cement mortar is favored. This study was initiated to four different pre-mixed polymer cement mortars which are produced in Korea. The for pre-mixed mortars were selected and tested with respect to physical and mechanical properties an proved that their qualities were better than those of common cement concrete mortars.

  • Literatures have considered mathematical model that change the job order of shipper for improving the operation time of yard crane. However, on the real site, it is impossible to change the job order decided according to the shipper's arrival order. Therefore, operation managers have been utilized the relatively simple strategy that job control is better but the process time of yard crane is longer due to the growth of yard crane's interference time and empty drive time. This study proposed a new yard-crane scheduling approach that decided the job order before the shipper's truck arrived the yard terminal. We utilize the Container Pre-Information Notice estimating the arrival time of truck. We developed the container terminal simulation model for validation of the effect of proposed scheduling approach. The results show that the proposed scheduling reduced the interference delay time and empty moving time of yard crane and shipper's truck delay time.

  • 'Fun' may be a basic desire of all human beings, but studies that combine both education and enjoyment were very limited, with the exception of the sports and games subjects. As a result, this study focused on the fun induced from the actual site of education, beginning under the premise that this can increase the effectiveness of education. In particular, it has been concluded that more fun is especially required in compulsory education that disregards one's opinion, with the Social Service Personnel that are required to undergo two weeks of compulsory job training selected as the test subjects. In order to comprehend how the 'fun factor' from the Social Service Personnel' job training influences the educational effectiveness, the causal relationship between learning flow, group flow and learning satisfaction has been proven using the structural equation model. Through this, the median between fun and education was found, as well as whether fun education has an actual effect on educational effectiveness. In addition, it is an opportuniy to emphasise the need for enjoyable education for not just Social Service Personnel, but for all involuntary learners.

  • This study was to verify the effect of art-education-oriented integrated human resource education (STEAM) on scientific competence and job competence of middle school students. The theme of the program developed for this study is "food design" using a 3-D printer. The 5 mockup lectures were developed for 237 students in ninth and tenth grades of Y Middle School in Gyeonggi-do Province, and the pre-/post-results were analyzed. As a result of analyzing the competence of STEAM education before and after the program, the job competence of general, science, and food science of students was improved after the program in general. Especially among three sub-areas of scientific competence, the change in component of research shows the most significant change in test statistics. The result of test statistics of food science job competence showed the most significant change among three sub-areas: general, scientific, and food science. This program was developed for on-site to be used for a school lecture, and the program may be reformed or used for different themes.

Influence of School Foodservice Dietitians' Work Value on Organizational Effectiveness: Moderating Effect of Expectation to the Institution of nutrition Teachers (학교 급식 관리 영양사의 근로가치관이 조직효과성에 미치는 영향 : 영양교사 제도에 대한 기대감의 조절효과를 중심으로)

  • The purpose of this study was to identify the influence of school foodservice dietitians' work value on job satisfaction, organizational commitment, and turnover intentions. Also, this study explored the role of the expectation to the institution of nutrition teachers as a moderating variable in three relationships: 1) between work value and job satisfaction, 2) between work value and organizational commitment, and 3) between work value and turnover intentions. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu${\cdot}$Gyeoungbuk province. A total of 509 responses were collected using on-site survey and online survey (response rate 59.3%). This study conducted hierarchical regression analysis to test the moderating effect of the expectation to the institution of nutrition teachers. Results of hierarchical regression showed that work value of status upgrade had a positive effect on job satisfaction to promotion opportunity and salary, and such effect was more significantly apparent in high expectation to new work. In addition, work value of status upgrade had a positive effect on turnover intention, and such effect was more significantly apparent in low expectation to new work environment improvement. Work value of work activity preference also appeared to have a positive effect on organizational commitment, and such effect was more significantly apparent in high expectation to social status and professionalism.

  • Establish standards and review procedures for on-site implementation of the emergency response plan required to establish by substances requiring preparation for accidents. Investigated for the examination content and standards for Process Safety Management (PSM) and Safety Management System (SMS). Safety Management System operator's comments and problems to be expected in the review process. Standards for on-site implementation and review of a person's ability to do the job does not require a high level of expertise. However, it has been created mainly to determine whether appropriate items to be included in the report and the contents presented.

  • Domestic plant construction sites have a tendency to become bigger, more various and complicated. Moreover frequency of industrial incident is increasing due to short project period, coexistence work condition and using heavy construction equipment. Installing safety facilities and safety training contribute to prevent incident. But mostly incident happens due to workers' unsafe action and wrong work method. Technically, it is very difficult for us to closely manage workers preventing incident. Therefore, the role of foreman who ordinarily works together with his workers is considered more important. Specific execution plan was drawn through industrial incident statistics from Ministry of Labor and questionnaire survey to interest parties(supervisor, safety staff and foreman). If foreman has raised sense of belonging and responsibility by conducting practical safety training for his workers, manages job site and receives proper compensation for these roles, it will be expected that it fully influences incident decrease.

  • Standard estimates are the numerical data of a unit quantity required for construction work such as the amount of materials, manpower, and the use of equipment required and are also a basis to calculate construction costs. Unfortunately, standard estimates for construction have also been used for garden construction these days as no standard estimates for garden construction have been developed or documented until now. As a result, many problems have arisen at garden construction sites since landscape construction and garden construction differ in terms of scope, size, design and construction methods. The purpose of this study was to develop standard estimates for garden construction for proper calculation of the cost of garden construction and to ensure gardens are created following appropriate construction processes. In order to develop standard estimates for garden construction, a preliminary survey was conducted on experts to understand current issues at first. After that, a questionnaire survey was done to examine problems of construction processes and ways of improvement, and on-site inspections were conducted utilizing CCTVs at construction sites to identify the actual amount of manpower required on site. Based on the results of the surveys and on-site inspections, a draft version of standard estimates for 5 types of planting work for garden construction was developed. Developing standard estimates for garden construction will serve as a stepping stone for the transparent and proper compensation for garden construction work, which will not only contribute to addressing issues between consumers and construction companies, but also to the stabilization of market economy and job creation.
