During five years (Year 2009~2013), Total victims of 72 %(81,560 people) and those 50.6 %(1,258 people) of death accident occurs in small scale construction site which operate 2 million USD less construction budget. Especially, falling death accident account for 785 people, in the share of 33.2 %(261 people) death disaster takes due to defect of original cause materials. The major safety issues in small scale work place take place while scaffold installation, disassembling, work-plate improper installation or non-professional skills of workers. Furthermore, labor subcontract systems make small construction site shortage of resources. Those workers regard work-plate as unnecessary and consumables supplies. Because of that most of workers use unsafe workplace in most construction site. Therefore, in order to prevent falling accident occurring in small scale work site, government should organize related regulations such as "Work site safety construction method" and then expands education support, financial aid, and sourcing safety supplies for work plate which offer broad variety experiences. Also, introduce certificate solutions for various work plates to improve safety function such as anchoring type method and anti sliding function.

According to the statistic of industrial disaster in 2006 presented by the Ministry of Labor, there were 10,235 people with occupational diseases adding 2,740 more people (36.6%) compared to the previous year. Concerning the occupational diseases, 1,607 people had brain-cardiovascular diseases comprising more than 15% of all occupational diseases, and excessive workload and occupational stress seemed to play important parts. According to Korean Society of Occupational Stress, among 7,000 workers at 254 businesses in Korea, 73% of them were reported to be exposed to potential occupational stress and 22% of them were reported to be under severe stress. The increase of occupational stress among workers comes from excessive competition caused by business restructuring, promotion competition, annual salary system and so forth. Occupational stress threatens the heath and even the life of workers and lowers business competitiveness. Using the Korean occupational stress reduction model to the workers at small and medium businesses in Incheon area, therefore, the project intends to measure the level of stress among office workers and examine its relatedness to the VTD subjective symptoms. In addition, the project intends to present some methods to reduce occupational stress and increase business efficiency at work by studying and analyzing the various elements that workers use to reduce their occupational stress.

Imported and exported agricultural products are facing a very difficult time due to the rising distribution costs spurred by the increasing labor and oil prices. High empty transfer rates, which take place on a return route after the regular transportation of imported and exported agricultural products, are especially a major cause of the rising distribution costs. In an effort to overcome those limitations, this study set out to examine the transportation stages connecting harbor warehouses, processing plants, and central distribution centers on the circulation route of such imported grains as wheat, barley, corn, and soybean and the transportation route from the warehouses devoted to exported agricultural products to harbors for such exported agricultural products as apple, pear, and persimmon in order to develop a model on the creation of a compound logistics complex for processing plants and transshipment of imported and exported agricultural products. The study also promoted the logistic rationalization of imported and exported agricultural products by creating a compound logistics complex that would combine processing plants for imported agricultural products and transshipment functions for exported agricultural products.

This study investigates the causes of poverty in Korea since the 1997 Economic Crisis by analyzing the composition and characteristics of the poor by the types of families. While the poor largely consisted of disadvantaged groups, such as the aged, the disabled, or the female-headed families before the Crisis, families headed by working-aged and non-disabled adults have represented a larger portion of the entire poor since the Crisis. The higher overall poverty rate in 1998 mainly resulted from the rapid increase in the number of the unemployed and the high poverty rate of their families. In 1999, the larger number of the unemployed poor exited from poverty by getting a job in the labor market, contributing to the reduction in the overall poverty rate. The significant number of families headed by working adults were poor in 1998, and the size of these working poor was not reduced in 1999. The poverty among this group has been caused by lowered wage rates and deteriorating job security. The findings from this study suggest that anti-poverty policies in Korea be improved to provide better income and employment assistance to the non-working poor and, more importantly, be extended to effectively reduce poverty among the working low-income families.

Purpose: Childbirth self-efficacy plays an important role in women's ability to cope with labor and delivery. Coaching has been gaining popularity as a way to promote cognitive, emotional and behavioral change. This study aimed to test the effects of a Coaching-based childbirth program on anxiety and childbirth self-efficacy among primigravida women. Methods: The study design was a quasi-experimental pre-post design. A coaching-based childbirth program was developed synthesizing concepts and techniques from the literature on coaching and was verified by an expert panel. It consisted of four weekly 2-hour small group sessions. Pregnant women were recruited from H hospital in Seoul. Childbirth self-efficacy and state anxiety were measured before and after the program. Results: Although there was a no significant reduction in anxiety, there were statistically significant increase for childbirth self-efficacy in the experimental group when compared to the control group. Conclusion: The program appears to increase childbirth self-efficacy for pregnant women. Future studies may benefit from using mixed coaching modalities and consider measuring health behaviors and obstetric outcomes to gain insights on its long-term impact.

Many Korean apparel firms have been adopting the global sourcing to enhance their competitive advantages. The purposes of this study were to identify the current status of global sourcing adopted by Korean apparel firms and to provide useful information for the other apparel firms planning the global sourcing. The questionnaire survey was conducted to 65 Korean apparel firms. The firms selected for this study were women's, men's, unisex casual wear manufacturers which made their products at offshore factories. The results show that about half of them started global sourcing before 2000. Unisex casual wear firms were already doing the global sourcing very actively and women's wear firms were followers. The major benefit of the global sourcing was the cost reduction. The firms that had made inroads into the global market find much satisfaction in global sourcing. These early adopters expected their sourcing countries as a future consumer market. The threatening elements of the global sourcing were the difficulties of quality control and labor cost rising. Cost and technical ability were considered importantly in selecting the global sourcing partners. The firms started the global sorucing before 2000 were greatly depended on offshore production. They concerned for the problems related to the global sourcing.

No-till direct seeding cultivation of rice has major advantages such as saving of labor and cost by eliminating tillage, preparation of seed bed and trans-planting procedure compared to the conventional transplanting cultivation. A field experiment was conducted to evaluate the effects of straw treatment and nitrogen levels on the rice growth in no-till direct-seeding cultivation. Rice straw, vetch straw, and the mixture of both of the straws were mulched on the surface of soil before seeding while 4 levels of nitrogen fertilizer, 0, 7, 9, and 11 kkg/10a respectively, were applied at 3 split times, 3-weeks after sowing, 5-weeks after sowing and the panicle initiation stage. Mulching of vetch straw significantly reduced seedling establishment of rice which may be attributed to low oxidation-reduction potential of soil by vetch mulching treatment. Vetch straw increased the concentration of soil ammonium leading to an extension of the greenish leaf to panicle initiation stage. Agronomic nitrogen use efficiency (AD $E_{N}$) in heavy-mixed straw mulching plots was lower than other treatments. Grain yield and AU $E_{N}$ in the vetch treatment were less affected by fertilized N levels. Conclusively, it is suggested that heavy straw mulching was not efficient for rice seedling establishment and nitrogen usage.e.

Spawn bottle cutting and spawn cake shredding machine has been developed to save the farm labor and operating cost for mushroom growing farmers. The prototype can cut the bottom and side of the bottle while shredding the spawn cake by one farmer. The cutting plastic shell is done by two couples of high speed disc saws that can cut cross section and lengthwise two side of the bottle, while spawn cake shredding is done by spike teethed rotating drum and wiremesh concave. The optimum speed of cutting disc saw was observed 1.700rpm both the cross cutting saw and lengthwise cutting saw in consideration of the cutting accuracy. And the location for the instalation of cross cutting disc saw was considered as around 4 mm above the table bottom , while the optimum clearance between two edges of lengthwise cutting disc saw was showed 86mm. For the sawdust spawn cake shredder , proper size of spawn sawdust granule was observed in the 15 x 15mm size withmesh concave with the shredding rum speed of 500rpm. The prototype can be reduce 73 per cent of working hours with the working cost reduction of 49 per cent compare with those of conventional operation.

This study was conducted to solve the problem of spinach harvesting done by manpower at the outdoor field during the cold winter season. Prototype spinach harvester was designed to dig, pick-up, and collect in a continuous operation for harvesting outdoor field-planted crawling type spinach. In the field test, two types of blades (Type A : angle of $150^{\circ}$, Type B : straight) were used for measuring the cutting loads of spinach and chain conveyor with lugs was used for picking up the root cut spinach. Prototype's vibrating blade reduced the digging power of the fixed blade by $46\%$. The loss was also very little ($0.7\%$) with a digging depth of 4 cm, an oscillation frequency of 748 rpm, and an oscillation distance of 33 mm. The working performance of the prototype spinach harvester was 38 hour/ha resulting to $96\%$ labor cost reduction compared to the conventional harvesting.

Fabrication of the hull plate demands a lot of man-hour and a high degree of technology. In recent years, commercial shipping orders have been fallen because of intensifying competition with low price of order and labor cost. In order to solve this problem, a countermeasure such as a cost reduction is required. In this study, we are dealing with the method of supplying the forming information of the hull to the production site. We reviewed studies of hull forming that have been proposed so far to develop a method for providing hull forming information. On the basis of given production plans from the production site of shipyard, we discuss how to convert shell plate to production plan. Then, we will discuss the efficiency of the distribution method through the network about the method of hull forming. Thus, we have modified the distribution method which was proposed before. Finally, we will introduce the enhanced method for providing fabrication information of the hull plate to the small and medium-sized shipyards.
