The history of Korea's overseas construction began in 1965, and the cumulative contract amount is about $180 billion over the last 40 years. During the period, Korea's overseas construction industry has played an important role for economic development. However, it seems that the industry is in a sea of trouble. Overseas construction orders have declined due to various reasons such as companies losing confidence, limited financing, lack of competitiveness, and so on. This paper addresses the brief history of Korea's overseas construction industry and the problems that the industry is facing. Then it suggests a few measures for the improvement of the industry.

The primary aim of this research is to summarize and discuss the problems that the hand tool manufactiuring industry of Korea is now facing. The study was performed mainly through the interviews with hand tool industry experts. Traditional design concepts are usually oriented towards the functionality of tools but often ignore the human factors such as ease of use, comfort, etc. As a result, for hand tools, mechanical and material aspects have been considerably enhanced but human factors have still much room for improvement.

Product liability(PL) and product safety(PS) is one of the most costly and confusing problems facing manufacturing today. Accordingly, this paper presents an integral process for product safety and product liability resulting from a defective product and proposes countermeasures of PL and PS for the four types of risk based on severity and frequency. Finally, we have presented a framework and practical procedure to provide the manufacturer with useful way of analyzing the risk potential of consumer products.

The problem of productivity improvement is one of the most challenging problems facing the world economy. This paper studies an analysis of improving personal-computer(PC) company productivity through factory automation. It attempts to analyze value added productivity at the company level. The index measured will effectively help managers supervise their companys. This study justifies that the proposed approach will stimulate manager's profit-motivation by providing them with value-oriented management instead of quantity-oriented method.

The productivity and quality are most challenging problems facing all companies. This paper presents a process improvement of the SMPS(switching mode power supply) assembly line through elimination of unnecessary operations, a proper factory layout, motion study, and line balancing techniques. The proposed assembly line increases the productivity by 23.9%, and decrease the proportion of nonconforming items by 48.9%.

This paper examines the long-run social welfare maximization problems facing public utilities, which includes consideration of the cost of capital or other fixed costs of production, from which it derives optimal investment decisions in a reliability differentiated pricing based market. Reliability differentiated pricing policies lead to straightforward mathematical results on optimal investment decisions in generation and transmission expansion planning. This paper presents the mathematical conditions for optimal investment decisions.

With the commercialization and full-timeization of the livestock industry, civil complaints continue to increase, and the livestock industry is facing a crisis due to social problems such as odor caused by livestock manure, soil pollution, water pollution, and environmental pollution. In order to increase productivity in livestock farms, the amount of livestock manure generated is increasing due to excessive use of protein feed and high-density breeding environment, and complaints such as odor and water pollution due to management problems are increasing rapidly. Livestock odor has emerged as a serious social problem, and due to growing complaints, conflicts between the Ministry of Agriculture and Forestry and the Ministry of Environment are even causing the livestock industry to lower its status. There is an urgent need for solutions to identify problems in the livestock industry and improve policies. This study aims to develop a " Abelmoschus Manihot Jinhuakui " brand that can improve the intestinal environment of livestock, reduce odors caused by livestock excrement, and improve the productivity of livestock farms in order to improve the increasingly serious odor problem in livestock sites. For Jeju livestock farms, which place more importance on the environment by securing tourists, eco-friendly feed additives were applied to the experiment, the results were derived, and the focus was on solving fundamental problems of odor generation through the development and packaging of feed additive brands. We aim to fundamentally solve the odor problem of domestic livestock farms, secure eco-friendly livestock farms, and contribute to reducing livestock odors and increasing productivity through research results that reduce ammonia levels in each livestock farm.
