There are several kinds of service standards for 3G($3^{rd}$-Generation) wireless communication as WCDMA, CDMA2000 and WiBro(Wireless Broadband Internet). Especially WiBro Wave2 system is a marked currnt issue. In this paper, we describe on the cell plan tool to desgin WiBro Wave2 network. For this, we treat from basic theory to practical substance to produce new(or modified) path loss prediction model for 2.3GHz. And we explain the method how to implement new technology MIMO(Multiple Input Multiple Output) deployed in Wave2 system. Also we emphasize on the importance of LOS(Line Of Sight) analysis in WiBro network design.

A shortage of construction field workers has been a serious problem, both in the developed and in the developing countries. As a solution for conquering this problem, these countries import foreign laborers from nearby less-developed countries. While this contributes to lessening the labor deficiency, foreign workers are relatively inefficient in productivity and are often exposed to the cross-cultural risks due to cultural differences, communication difficulties, different work ethics and customs, etc. Despite these facts, construction firms do not well address these issues and are lagged in establishing an appropriate management strategy against it. This paper presents a practical management plan for foreign construction workers through Focus Group Interviews (FGI) and survey investigation. On this basis, this study examines the level of awareness and important managerial aspects of the issue of foreign laborers. Finally, it suggests a cross-cultural and ready-to-use practical human resource management plan for facilitating the foreign worker's productivity.

This study proposes a plan to construct an integrated platform that reduces manufacturing costs and efficiently produce by integrating the systems of main producers, production subcontractors, and raw material subcontractors for the production of food packaging containers. The production plan of food packaging containers and raw materials is established in real time between the main producers, production subcontractors, and raw material subcontractors in consideration of the demand characteristics of each product. It establishes basic information that all processes from the production planning stage to the forwarding stage of the product are linked to each other. The progress of each producer of interlinked processes is shared in real-time to improve productivity and quality of food packaging containers and raw materials and reduce manufacturing costs. By monitoring the system of the main producer and the production subcontractor in real time, the production of food packaging containers is performed in a timely manner, thereby improving productivity. The application of the plan-do-check-action (PDCA) process, which includes planning, execution, evaluation and improvement in the production operation processes of the main producer, production subcontractor and raw material subcontractor, enables improved production compliance rate. The contents of the main producers, production subcontractors, and raw material subcontractors are managed in real time, then a converged production management system is established through the platform proposed in this study to ensure timely supply and demand of raw materials without delay in ordering.

In the 4th Industrial Revolution, the competitiveness of the software industry is important, and as a solution to fundamentally secure the competitiveness of the software industry, education classes should be provided to educate high quality software personnel in educational institutions. Despite this social situation, software-related classes in universities are largely composed of competitive or individual learning structures. Cooperative learning is a learning model that can complement the problems of competitive and individual learning. Cooperative learning is more effective in improving academic achievement than individual or competitive learning. In addition, most learners have the advantage of having a more desirable self-image by having a successful experience. In this paper, we apply a pair check model, which is a type of cooperative learning, in operating system classes. In addition, the class procedure and instruction plan are designed to apply the pair check model. We analyze the test results to analyze the performance of the cooperative learning model.

The number of patients with dementia in Korea is estimated to be 576,000 in 2013 and 648,000 in 2015, and 840,000 in 2020 and 2,710,000 in 2050. Therefore, it can be expected that the number of patients with dementia will increase among the elderly patients who are looking for dentistry. Dementia and oral hygiene are closely related, so the future role of the dentist is very important. In order to treat effectively the patients with cognitive disorders, we should consider effective communication methods with them. Xerostomia is another important factor affecting oral health of dementia patients. In establishing the dental treatment plan, the most appropriate treatment method should be selected considering the characteristics of individual dementia patients and all possible efforts should be made for successful treatment results.

Improvement is required to solve problems depending on long term use of signal equipment in the existing city railroad and to raise quality of passenger services. Accordingly, for more efficient improvement, we examined the procedure of executing construction of the communication based train control system in Korean city railroads, which is globally studied. The procedure of executing construction of the system is to present a plan for construction first of ail and then to prepare a strategy for construction of the system. It is required to establish a procedure for execution in each step depending on the prepared strategy and then to establish a detailed execution plan. We studied such an execution procedure, divided the execution procedure for application of the train control system through five steps to prepare the execution procedure.
