In any form of construction work, it is essential that accidents be prevented at every stage from foundation preparation to build completion. For this, it is necessary to use models that can assess risk and provide instruction for safe work processes so that the risk of accidents is reduced. Currently, however, very few models can perform these tasks. In this paper, we presents a model that assesses risk quantitatively by analyzing risk factors involved in stage of construction such as foundation work, erection work, structural work, equipment work, finishing work and etc work. The model performs assessment based on examples of accidents and by investing actual conditions during construction. In addition, we presents in this paper a safety management system was developed to assess risk during construction and to effectively train laborers.

Labor productivity issues within the construction industry are receiving increasing attention. With the improvement in the standard of living, domestic laborers are avoiding 3D (Difficult, Dirty, and Dangerous) jobs by degrees. Because of this situation, the problem of insufficient labor is exacerbating in several basic industries. In particular, insufficient labor is a serious problem in the construction sector, where the workers are ageing and labor costs are increasing. In this study, we adopt a systematic approach to identify factors that influence labor productivity and analyze the causality between the factors and their ripple effects with the aim that the results of the study will help improve labor productivity and ensure its effective management.

The purpose of this study was to analyze the local government of multicultural family policy. For this study, researchers first compared Canada, Australia and Japan and, second, analyzed the foreign policy plan data in Korea. The findings were as follows: First, Gyunggi province had many plans for foreign laborers and Gangwon, Kyungbuk and Jeonnam provinces had many plans for multicultural family wives. Second, many local governments had few economic independence programs for multicultural family wives, except Gangwon and Kyungbuk provinces. Third, many local governments had no school or study programs for children of multicultural families, except Gangwon, Kyungbuk and Chungnam provinces. Fourth, Canada and Australia had many sources of public information and many educational opportunities for people to gain understanding but local Korean governments had few of these programs. Finally, Canada and Australia had many international programs for immigrants to maintenance their culture but local Korean governments have none of these programs.

Construction companies are now trying a variety of cost-cutting strategies in the midst of recent slump of construction market. Notably, contract workers and local hires are accounting for increasing portion of management manpower as a part of their cost-reduction drive. However, construction site manpower researches to date have focused primarily on productivity analysis of site laborers, with little attention to the productivity of site management resources. This study aims to analyze the staffing status of office building construction site management manpower in reference to project size. Conclusions herein will provide basic inputs for subsequent attempts to build a model to enable efficient staffing of construction site management manpower.

Laborers have its great effect upon the quality of the manufactured goods directly. This presentation will treat its subjects to rearrange the QC Circle activities in Korea concerned with the Korean way of living and their judgement of value, and present its direction in future. Examining all the present problems such as the occupational morality of the Korean people, wages, labor productivity and its distribution, working hours, disaster, separation rates, and we will see how those factors effect the laborer`s expectation, his will to work and $\Omega$ C Circle activities, compared with those of Japan.

Malodorous gases give discomfort and harm to laborers and residential neighborhoods and therefore, the removing odor materials emitted from plants and industrial facilities is important subject. The main ingredients of alkali odor are $NH_3$ and $CE_3SH$. The adsorption characteristics of odors were studied using four different activated carbon fibers(ACF) and active carbon(AC). Alkali odor was removed by using ACF impregnated with $H_3PO_4$ and $H_2SO_4$ and treated with $HNO_3$ and NaOH. The experimental result showed that ACF has a higher removal efficiency than AC. The adsorption capacity was increased with the impregnation and surface treatment, and $H_2SO_4$ was the best impregnant for the removal of alkali odor.

The objectives of this study are to provide advices and methods for cultivating labor in the digital cultural contents industry in the Chung-Nam Province. For the purpose of this study, review of theoretical and practical literature, identifying the present status of affairs, and three times FGI and surveys were executed. The results of research show a lack of professional labor in the digital cultural contents industry; even so most of laborers want to get a job in or around the Seoul region. To activate digital cultural contents in the local area, a development model for the Chung-Nam digital cultural contents industry was introduced and four strategies were also suggested. The nurture of a professional skilled labor force through a strategically designed joint relationship between university and companies in the digital cultural contents industry was found to be quite necessary. In this way, the need for specialized training and education in the university classroom can be supported.

The safety block which prevents drop of laborers at high altitude was analyzed by finite element method. Elastic analysis was done by Ansys ver. 11.0. and tetrahedral meshing was used. As load applied more vertically at the fixed face of saw tooth, the stress concentration became smaller and the load distributed broader. When load worked at saw tooth and the shape was more straight to the direction of load, most stresses except principal stress became smaller. When the area of the load increased, principal stress and equivalent stress could be decreased simultaneously. A principal stress and other various stresses occurred in 3D shape, therefore revised model which has smaller equivalent stress than other models shows excellence on the stability and the credibility.

Purpose: Slow manual harvesting of rain-fed chickpeas cultivated in fallow fields in developing countries have encouraged the design of a mechanical harvester. Methods: A tractor-pulled harvester was built, in which a modified stripper header detached pods from an anchored plant and a chain conveyor transferred material. The stripper harvester was redesigned to use: 1) the maneuverability of tractor-mounted frames, 2) the adaptability of floating headers, and 3) the flexibility of pneumatic conveyors. Results: A mobile vacuum conveyor, which was an innovator open system, was designed for the dilute phase transferring mode for both grain and material other than grain. A centrifugal fan transferred harvested material to a cyclone separator that settled harvested material in a grain tank 1 m high. The machine at the spot work rate of $0.42ha{\cdot}h^{-1}$ harvested chickpea pods equal to the output of 16.6 farm laborers. Conclusion: The low cost and reasonable projected purchase price are the advantages of the concept. Additionally, the shattering loss reduction confirms the feasibility of the prototype chickpea harvester for commercialization.

In this study I made an analysis on the background of creating of Minimal Art and thought of its artists during 1950~1960 and their works. Starting from the early Modernism that tried to depict the life of farmers and laborers in the chaos of war and viewing the art as the tools describing the life itself, minimal art took its root as furniture in ordinary life passing through the era of Surrealism and Dadaism. In 20th century, furniture designers were trying to seek new trend of modern furniture in the perspective of balance and immaculateness while excluding emotion and overall feeling through minimalism. These efforts result in the introduction of immaculateness and refinement in furniture design. Hence, this study is to represent a new trend of furniture design utilizing the margin of furniture in complex lives through formative characteristics that minimal art beholds.
