The purpose of this study was to identify the educational and ecological factors (environment and infra-structure) associated with workers' participation to safety and health education at work (SHEW) based on the PRECEDE constructs. A total of 590 workers (484 in manufacturing and 106 in construction companies) finished the self-administered survey. Survey packets were delivered to the safety and health manager (SHM) in survey companies and the SHMs conducted the self-administered survey in their companies. The questionnaire includes demographics, epidemiological constructs, and educational and ecological constructs based on the PRECEDE model. Participation to SHEW was better in the manufacturing sector than in the construction sector (p<.001). Environmental, reinforcing, and enabling factors were better in the manufacturing companies than in the construction companies. Male worker, better perceived efficacy of SHEW, higher social support for SHEW, assignment of SHM at work, and better safety and health management level at work were significantly associated with workers' better participation to SHEW (p<.05). Those factors accounted for 45.9% of total variance of workers' participation to SHEW.

The occupational injury and illness(OII) was influenced by the various factors. This study was planned to investigate the pathway of the activities of OSHM on the rate of OII via worker's participation. The survey on the trend of the activities of OSHM was used. The sample size of manufacturing industry was 3,000 enterprises and that of construction was 1,000 enterprises. The survey was done by interview method with structure questionnaire. Questions about the activities of OHSM were integrated into one category using factor analysis. The enterprises with OII has more activities of OSHM than that without OII. Among enterprises with OII, the level of the activities of OSHM was positively correlated with the rate of OII. The activities of OSHM has influenced on the rate of OII directly and indirectly via worker's participation and the activities of prevention of accident. Worker's participation also has the direct effect and indirect effect on the rate of OII. Worker's participation in construction sector has more effect on OII than that in manufacturing sector.

This study aims to inspect the effect of the yungbokhap education on the development of students' mathematical competence by analyzing students' mathematical discourse in math-based yungbokhap instruction designed by Moon(2014). Specifically, this research focused on the analysis of students' participation structure. The reuslts shows that the students' competence for mathematical communication and inquiry has been improved through the instruction. In particular, the students were increasingly engaged with consensual talk. Also, in the beginning stage, the students tended to unconditionally criticize for others' mathematical opinion. Through the class participation, they gradually developed the competence to express their mathematical ideas to their peers with reasonable mathematical bases. These results suggests that the mathematics-based yungbokhap instruction has positively contributed to the improvement of students' mathematical competence. Based on the results, this paper presented implications for mathematics-based yungbokhap instrcution.

Seismic load is distributed to modes of a structure through the modal participation factor(MPF). The modal participation factor is essential to analyze structural response under earthquake load. MPF of a real structure differs from that of analytical mathematical model due to the error induced from analytical assumptions and during the construction. In this study, an identification method is proposed to calculate the 1st MPF of real structure based on $H^{\infty}$ optimal model reduction. The MPF is obtained from the relationship between observability and controllability matrices realized from system identification and those of a prototype 2-degree state space model. The proposed method is verified thorough numerical examples.

Citizen's involvement in forest decision-making is recently acknowledged as a potential solution to forest management conflicts. Through participation, affected citizens become a part of the decision-making process. This paper focuses on the use of collaborative and participatory model(CPM) for urban forest management. The model, which is exemplified by the Daejisan case in Yongin-si, Gyeonggi-do, Korea, utilizes the collaborative decision-making structure and the gradual level of resident participation in urban forest management. As a result, the committee in the model contributed to building partnerships among different interest groups and then to constructing environmentally compatible urban park. Furthermore, an improvement in the levels of resident participation was manifested in the process. These characteristics of CPM can encourage participation and cooperation among stakeholders and ultimately contribute to realizing sustainable urban forest management.

The load distribution to each mode of a structure under seismic loading depends on the modal participation factor. The factor of an idealized analytical model, however, is different to the actual one due to modeling and construction error. Therefore, there exist limits on the estimation of actual behavior. In this study, an identification procedure for participation factor based on vibration test is proposed. The procedure has an advantage that the mode shape vector can also be estimated directly from the participation factor. The numerical simulation using a three story building is performed to evaluate the proposed procedure.

The purpose of this study is to analyse the change of agricultural labor participation and decision-making involvement of rural women in Korea from 1960s to 1990s. For analysis of these changes, I used the data surveyed and collected by different researchers during those times. During last 40 years, rural society and the mode of agricultural production rapidly changed according to the development of Korean industry. Agricultural labor participation of rural women increased since the mid 1970s. Their agricultural labor expanded into full ranges of farming. Their decision-making involvement also expanded into all divisions of farming. However, they did not have decision making power as much as they contributed to farm labor The expansion of rural women's labor within the sphere of farm production has not substantially altered the decision-making power structure within the farm household.

As the industrialization and urbanization are advanced rapidly, the apartment housing has been in excessive supply. Also, the apartment housing that offers modern people a comfortable life has been the typical housing type in Korea. Meanwhile, people today have lost their morality and communities have been dissolved because of a sudden social change. But the lost morality can be recovered when the communities are established. As more increasing in the residents' demands, it is enlarging of residents' interests and participations in pursuit of quality of life. In this process, residents' participation has occurred of their free will not only in offline communities but also online communities. For developing of IT technology, people using internet have exceeded 75% and development of online communities in apartment housing have boundless potentialities despite in a delicate situation that is at the same time and same space. The purpose of this study is that examine the possibilities and directions of participation, as it attempts to grasp the present conditions and problems of online community. In the study, we searched the word, apartment housing, on portal site to apprehensive the status of residents' voluntary participation on online community. According to research, residents' voluntary participation on online community was divided into three frames, such as remodeling, planed resident and designing friendship. Finally we found out resident's contents of communication and structure of their participation by these frames. As a result, participation on online community helps residents who have been not take part in offline community because of limited time in spite of difficulty of lasting participation. From now on, it will have possibility to increase and revitalize new communities on the purpose.

This study explores the effect of the properties of digital infra on customer participation to explain how customers' initiatives impact the marketing process in the digital environment. Also the effect of the accumulated information through customers' information sharing on their initiatives in the marketing activities can be discovered. These effects can be better understood by developing comprehensive model and employing large sample empirical test. Study1 identifies the properties of digital infra which overcomes the limitations of off-line environment in customers' participation - Information openness, connectedness, community interaction and structure clarity - and how these properties activate customers' participation in the marketing process. Study2 shows the process structure of reverse marketing activities in the digital environment. These findings deliver the fact that customers' initiatives in the marketing activities will be accepted generally under the digital environment. Consequently, this study suggests some managerial implications for completely different marketing strategies in response to customers' initiatives in the marketing activities under the digital environment.

This study is concerned with the estimation of vibration-field of a cylindrical structure by modal expansion method(MEM). MEM is a technique that identifies modal participation factors using some of vibration signals and natural modes of the structure: The selection of sensor locations has a big influence on predicted vibration results. Therefore, this paper deals with four optimal sensor placement( OSP) methods, EFI, EFI-DPR, EVP, AutoMAC, for the estimation of vibration field. It also finds optimal sensor locations of the cylindrical structure by each OSP method and then performs MEMs. Predicted vibration results compared with reference ones obtained by forced response analysis. The standard deviations of errors between reference and predicted results were also calculated. It is utilized to select the most suitable OSP method for estimation of vibration field of the cylindrical structure.
