In order to reduce business latency and packet loss rate, to improve the throughput of integration of heterogeneous wireless network, to achieve load diversification and to improve end quality of service, while there are many problems on the dropout rate of the traditional load balancing algorithm in processing throughput, delay and business, therefore, gateway load balancing algorithm is proposed in this paper. All terminals in the access network can reflect the effectiveness of the average network load level of the network, this algorithm will gain weight of the load in the network of small business terminal to switch to the network load which is light. First, it defines the heterogeneous networks and network terminal payoff function utility function, which are used to characterize the experience and network QOS terminal load situation, and then presents the specific processes of the gateway load balancing algorithm. Finally, switching decisional load balancing algorithm, proposed by Yan X, etc. is compared with simulation experiments and it shows that: the proposed gateway load balancing algorithm has strong robustness to achieve network load balancing and to achieve a balanced use of network resource.

본 연구는 항만하역 작업안전에 대한 집단 간의 인식차이를 분석한 연구로 기존 연구에서는 항만안전요인과 안전분위기, 안전행동에 대한 관계성을 파악하였지만 전체적인 항만하역 관련 재직자들을 대상으로 하였기 때문에 집단 별로 세분화된 시사점을 제공하기는 어려웠다. 또한 안전사고는 경험이 있는 집단과 경험이 없는 집단이 인식하는 마인드가 달라질 수 있기 때문에 안전사고 경험 유무에 따른 인식차이를 파악하고자 하였다. 분석결과, 관리경영진과 현장근로자는 항만하역에 대한 안전요인, 안전분위기, 안전행동에 대하여 유사하게 인식하고 있어 관리경영진과 현장근로자와의 생각의 차이가 크지 않았음을 알 수 있었다. 하지만 직간접적으로 안전사고 경험이 있는 집단이 경험이 없는 집단에 비해 안전요인, 안전분위기, 안전행동 등에서 낮은 인식을 하고 있었다.

This study is a study to analyze the difference in perception among groups on the work safety of port loading and unloading. In the previous study, the relationship between port safety factors, safety atmosphere, and safety behavior was identified, but it was difficult to provide subdivided implications for each group because it was targeted to the incumbent workers related to port loading and unloading as a whole. In addition, since the mindset perceived by the experienced group and the inexperienced group may differ, we tried to identify the difference in perception according to the presence or absence of a safety accident experience. As a result of the analysis, management and field workers similarly recognized the safety factors, safety atmosphere, and safety behavior for port loading and unloading. Therefore, it can be seen that the difference in thinking between management and field workers was not large. However, the group with direct or indirect safety accident experience was less aware of safety factors, safety atmosphere, and safety behavior than the group without experience.
