건축, 구조, 기계, 전기, 토목, 조경 등 IT와 관련된 다양한 산업 분야에서는 각 산업의 기획, 생산, 운영등 단계별로 다양한 주제를 가지고 논의 및 시뮬레이션을 통하여 각 업체별로 의사를 개진해 나간다. 그러나 업종별 공정에 맞는 커뮤니케이션이 원활히 이루어져 나가기는 힘들다. 이러한 이유 중 가장 큰 부분은 데이터들이 다양한 뷰어(Viewer)들을 통하여 2차원적으로 보는 부분이 큰 비중을 차지하는 것에 비해 실제 결과물은 3차원적으로 다루어지고 있기 때문에 과정과 결과간의 격차로 인하여 벌어지는 문제가 크다. 각각 다양한 분야에서 생산되는 데이터들의 불확실성, 표현의 애매모호함으로 인하여, 이전 공정 단계에서 받은 데이터들을 현재의 공정 단계에 맞는 데이터로 변환되는 과정이 생긴다. 불필요한 과정들이 반복되는 사이 모든 공정이 지연되고, 많은 예산이 소모되는 등 많은 문제들이 발생되고 있다. 따라서 본 연구에서는 다채널을 활용한 VR 시뮬레이터로 몰입감을 높이고, 실제와 유사한 실감형 시뮬레이션으로 엔지니어링 VR 시뮬레이션이 가능함을 알 수 있었다. 향후에는 사용자의 용도와 목적에 따라 다양한 분야에서 활용의 범위가 넓을 것으로 기대되며, 많은 공간과 비용이 드는 현재의 다채널 시뮬레이터 형태를 보다 공간과 비용의 소모가 적고, 이동성을 갖춘 이동형 다채널 VR 시뮬레이터에 관한 연구가 필요하다.

This study investigates the relationships among SMEs' innovation capacity, standardization education activities, and performances. Employing about 900 SMEs in the ICT and electronics electricity industries, this study used regression analysis and examined the effects of standardization education activities on performance and the moderating effect of innovation capacity. The results indicate that standardization education activities positively affect SMEs' production and quality improvement and R&D activity improvement. The results also show that R&D investment ratio moderates the relationship between standardization education and production and quality improvement. This study provides practical insight into why firm managers should pay attention to standardization education and innvation capacity to improve firm performance.

Purpose: This study intended to investigate how health and safety organization, management, activities and safety culture of healthcare industries are different from other industries (food, lodging, gas, and electricity industries). Method: Data were analyzed using '2005 The National Survey for Occupational Safety and Health Tendency'. Results: For health and safety training, both new training and regular training time of healthcare sector was lower than comparison sectors. For health and safety manager assigning form, there were many case in healthcare sector to assign a safety manager as a deputy and a health manager as an additional job, there were some differences from comparison sectors. It was found that establishment of countermeasures by cause investigation and analysis execution for occupational accidents in the healthcare sector was lower than comparison sectors. For health and safety activities and safety culture awareness, they were estimated in healthcare sector to be lower than comparison sectors. Conclusion: Healthcare sector had relatively lower health and safety activities and safety culture awareness compared with comparison sectors. So, it is required business owner's concerns and efforts to assign exclusively responsible health and safety manager and to activate health and safety training and occupational accident prevention.

The textile industry in Korea, the dyeing sector is an energy-intensive sector and has low per-unit productivity due to its labor-intensive nature. If the defective rate of dyed fabrics is high, additional costs are incurred due to an increase in production cost due to re-dyeing. Therefore, the goal of the dyeing factory was to minimize the defect rate rather than to save energy. It was difficult to check the dyeing state of the fabric in real time due to the risk of accidents due to burns or pressure when dyeing in a high-temperature and high-pressure environment. In this paper, a complex sensor that can measure the exhaustion rate of dye solution in the dyeing machine using turbidity, pH, and conductivity sensors was proposed, and the experimental method and experimental results were analyzed.

We explore how stock returns and volatility have been impacted by securities market stimulating and controlling plans during the 1980-2004 period, using return analysis, event study, and BFL tests. First, we examine effectiveness of the stimulating plans for a depressed market and the controlling plans for an overheated market with respect to different firm sizes and industries as well as the whole market. KOSPI, large-sized, finance, and manufacturing company stock prices significantly rise following stimulating plans, implying that the plans are quite effective. Controlling plans also seem effective as stock prices stop rising and tend to decline following the plans. Second, we test whether securities market plans have any further impact with respect to fun sizes and industries in addition to the impact on the entire market. Only large-sized stocks show additional response to stimulating plans, while small-sized, electrical-electronic equipment, distribution, and manufacturing industries are further impacted by controlling plans. Third, the results of BFL tests show that volatility does not change around the announcement dates of stimulating and controlling plans. It appears that securities market plans have no impact on volatility. Only stock returns respond to the plans.

This study was performed to investigat the prevalence rates disease in industrial workers (16, 453) in Pusan city from Jan. 1, 1993 to Dec. 31, 1995. The results were as follows: The male to female ratio was 1.9:1.0 and average age was 43$\pm$17 in male, 38$\pm$15 in female of subjects. The percentage value of patients was 14.0% in male, 7.4% in female of total patients 1, 932 (11.0%). The prevalence raters of pulmonary tuberculosis, hepatic disease, and occupational hearing loss were significantly increased in male than females (p<0.001). But anaemia and organic solvent poisonings significantly increased in females than males (p<0.001). The prevalence rates of hepatic disease increased significantly in below 29, 30-39 and 40-49 age groups, that of cardiovascular disease increased significantly in the age group over 50 years (p<0.001). According to industrial types, the prevalence rate of cadiovascular disease increased in electricity and constration and shoes and rubber in disease, there of hepatic disease increased in primary metal, transportation and maintenance and other industrial, those of occupational hearing loss in drink and food and machinery. The prevalence rate of disease increased significantly long working duration in all diseases except lead poisoning.

This study was intended to analyze the effects of the selection of excellent design product by the KIDP(Korea Institute of Design Promotion) on the business performance of the company focused on the start-up with relatively low competitiveness. According to the statistics of KIDP in 2013, a design accounted for 27.53% of the factors affecting the sales of products and a design was the most important factor among the factors affecting the sales of products for the small sized company in terms of the scale of company. In addition, looking at the trend by industry in the data collected for this study, the technology-based industry showed a relatively higher growth rate than the retail industry and other industries. In this study, the author surveyed 186 companies of the companies that recognized the importance of design in difficult management conditions and received excellent design product certificate from KIDP(2013, 2014 and 2015) and empirically verified whether there was any difference in business performance between the start-ups with a business history of less than 7 years and the ongoing firms with a business history of more than 7 years. To evaluate the value of design, we used analytical method of measuring related values by comparison between groups. In addition, we also analyzed the difference in business performance(sales) between manufacturing companies, where the role of design was relatively large, and non-manufacturing companies among companies that received the excellent design product certificate. We have established a study hypothesis that the selection of excellent design product by the KIDP would have more positive effect on the business performance(sales) of the start-up compared to the ongoing firm, and conducted an empirical analysis by comparing both the year before and the year after the selected year. As a result, we found that the selection of excellent design product by the KIDP has a positive effect on the business performance of the start-up, and the selection of excellent design product has a significant effect on the difference in business performance between manufacturing and non-manufacturing companies. This study was conducted in the hope that the government actively supports the design-related policies so that the selection of excellent design product become an important indicator of the business performance of the start-up, and thus the design management will be a way to enhance the competitiveness of the start-up.
