The management of municipal solid waste (MSW) is essential for every community; and, it is currently a major challenge in Nigeria. This paper provides an overview of the current MSW management trends in Nigeria and proposes new sustainable MSW management systems. Across Nigerian cities, MSW management is characterized by inefficient collection and transportation to disposal sites. Collection services do not reach some unplanned areas and slums due to poor street network. Even some planned areas are not reached by collection services. The informal sector contributes to waste collection, resource recovery and recycling; however, their activities are not recognized by the governments. Markets exist for recovered materials but more efforts need to be geared towards intensive recovery of materials and expansion of these markets. Despite the high proportion of putrescible matter in MSW, the only form of treatment commonly used currently is open burning for volume reduction. The high organic fraction presents a great opportunity for composting and anaerobic digestion. Ultimate disposal is currently done in open dumpsites. This needs to be upgraded to engineered landfills that are properly sited and adequately operated by well trained personnel. There is an emerging waste stream of concern, electronic-waste (e-waste), that requires urgent sustainable management as e-waste are currently co-disposed with other waste streams or burnt in the open posing detrimental health impacts.

This study aims to analyze the level of members' awareness of records management in the Republic of Korea Army within the institutional context extensively. Accordingly, in-depth interviews were conducted after comparing and analyzing the institutional systems that restricted the members' record management activities. As a result, it was identified that the members were confused by the inconsistency among the systems that defined the work procedures, and that the value of responsibility and efficiency in the records management system does not match the organization's goals. Therefore, the legal justification of the system should be improved in harmony with the responsibilities and efficiency and to match them with the organization's objectives. Moreover, the improved system should be internalized by the members through instructions that are relevant to the content of the system. This study intends to increase awareness in the records management system and improve the system as well.

Since mid-1990s, demands for programmer have been decreasing, and the experts of planning IT strategy and solving overall management issues with IT have been increasingly needed. IS experts would have many different types of job as time passes, and they need variety of job competencies to meet their career paths. The purpose of this study is to investigate the potential careers to suit MIS major and the needed skills in that field to develop MIS Curriculum. We asked to the personnel working in the IS organization and user departments to evaluate the current MIS curriculum of 4 year colleges in Korea and to let us know what jobs are the most important for them, what the core job competencies for them are. The results of study show that there are several courses the users and IS experts regard as core courses: Introduction to Management, Project Management, Introduction to MIS, DBMS, ERP, Systems Development Methodology, and IS Strategy Planning. IS experts regard the data and application integration, IT evaluation and strategic planning as the important jobs, and the most important job competency to conduct those jobs is the category of interpersonal skills, and business management knowledge, IT skills are succeeded.

Major findings were: first, alliances between portal companies and content producers; portal companies and internet services; e-commercial sites and internet services were the most frequent partnerships engaged. Second, the most important motive for and type of the strategic alliance were: 'the commercialization and marketing of new product' and 'joint distribution and marketing agreement' respectively. Third, the most important factor for the successful alliance was 'a close examination of partners' core business value and competence'; and the factor most hindering the successful alliance was 'a discrepancy on capabilities of partners' core personnel. Finally types of internet business were significantly related to perceived satisfaction toward strategic alliance.

In this study, appropriate preventive measures are suggested as follows by analyzing industrial accident cases occurred for five years of company J and workers' survey. First, personnel management including meticulous shift work and rotation task for older workers should be made strictly in terms of safety and health management. Second, Industrial disasters occurred more in spring than in other seasons, so safety management will have to be enhanced in spring. That is, to reduce industrial disaster various occupational safety and health activities to prevent spring fatigue are needed. Third, to improve safety consciousness of workers, penalties for those who have not received safety training and for people without protective equipment are required. Also, hazard prediction training such as Tool Box Meeting shall be proceeded. Fourth, building of proactive safety culture that the workers themselves handle risk factors is urgent. Fifth, the company-wide safety and health programs including safety awards and cases presentation are needed to be planned.

The waterworks company is in charge of managing water facilities buried underground, and the management has been centered on manholes. However, since there is no standard management manual, it has been impossible to introduce and operate a systemized managing tool by water service providers and managers, and manhole management has been carried out by individual data recording personnel for each water service provider. When the management is carried out individually, the data to be shared by other waterworks managers tend to be privatized, and consequently, it may become a big obstacle to proceed with many civil works such as emergency leak repair, road excavation, replacement of old buildings. This report introduces RFID (Radio Frequency Identification) system which is based on the magnetic field capable of IOT. It also describes the necessity of leveraging the system for smart managing of pipe management record that has been done by hand writing. The RFID system includes RFID marker, data reader, portable computer operating program, and data base server operating program. In this system, the data is managed with a single communication device, and it would be possible to share the information on the underground facilities and water treatment facilities. This RFID technology is expected to provide water service providers with opportunities to develop more scientific and modernized underground facilities information systems.

Purpose: This study is to analyze the purchasing process and distribution management requirements for teaching materials that have important meaning in the practical field of preschool education. Research design, data and methodology: A structured questionnaire was used to survey 103 childcare staffs regarding the purchasing process and distribution managements. The collected data underwent Likert's 5-point scale analysis and keyword grouping. Additionally, ANOVA was conducted to examine the distribution management demands based on demographic characteristics. Results: The purchasing of teaching materials involved more offline channels than online, and the purchase decisions were predominantly made by principals rather than teachers. Although the purchasing process is similar to that of general businesses, there are difficulties in purchasing due to the disorganized distribution channels and limited accessibility to product information. Additionally, the management of inventory for teaching materials is challenging due to limited personnel and storage. Childcare staffs have requirements for classification systems, evaluation criteria, environments and policies related to teaching materials distribution. The need to introduce a teaching material evaluation and certification system to ensure quality was not high. Conclusions: Most of the respondents recognized that strict management and measures should be taken for the distribution of teaching materials. There were differences in the demand of teaching material distribution depending on the respondents' status, age, education, and experience.
