Domestic construction industry has faced with many problems in productivity, quality, safety and skilled-labor availability because of the national economic depression, insufficient supply of skilled labors and so on. There is a growing need for improving productivity and quality, and savings in cost. In the case of advanced countries, they have made a number of research efforts to solve these problems with construction automation and robotics. Recently, there are growing interests in construction automation and robotics but such interests have not been further increased due to the difficulties in gathering or accessing valuable information on the research and development of construction automation and robotics. The main purpose of this study is to provide a web-based research database and decision support system for an effective research and development of automated construction system and robots. It is expected that this system would be able to provide a framework for the successful research, development and implementation of the construction automation and robotics in domestic construction industry

This paper presents the relationship between the pace of structural change and the magnitude of employment growth in the manufacturing sector in OECD countries. To measure the pace of structural change, the compositional change index in value-added in manufacturing sector is introduced. For mid to long-term there seems to be a positive relationship between the pace of structural change and the magnitude of employment growth. In those countries with higher value of the compositional index, the employment growth in manufacturing sector was generally higher. To analyse the characteristics of structural change in manufacturing sector, this paper classifies manufacturing industries into groups: one based on technology, one on orientation, one on wages and one on skills. The international comparison of manufacturing sector's employment patterns based on above four classifications are presented. International comparison suggests that Korean manufacturing sector move into jobs with more skills and knowledge The structural change of SMEs and large firms are compared based on above four classification methods. It is shown that SMEs' employment in low value sectors, that is low-technology, labor-intensive, tow-wage, and unskilled sectors, have risen faster than SMEs' employment in high-technology, science-based, high-wage and skilled sectors. Large firms' employment have been mainly increased in high value sectors. However, the employment growth of both large and small firms have been concentrated on production worker-intensively-using sectors, i.e. unskilled sectors. This widened the wage differential of production workers by firm sizes and concurrently led to severe shortage of production workers for SMEs, which has little ability to pay high wage to production workers because they usually belong to low-wage sectors. Korea need to push SMEs forward to high value sectors. The premise of that is, however, to pull large firms out of production worker-intensively-using sectors.

The study for soil has been conducted separately by several areas such as soil mechanics and soil chemistry. Soil is important in terms of prediction of how the plant grow with nutrient requirement. Also, soil is important for machines to work on to solve labor shortage and save farmers from harsh environment during farm work. To meet diverse needs related to soil in agriculture, the soil related study needs to be conducted synthetically. Thus, we tried to obtain the data related to soil chemistry including pH and Electrical Conductivity (EC) with data related to soil mechanics including Cone Index (CI), moisture content, soil classification. Specifically, the condition of the field was set to be cultivated at least for five years continuously at a first step. The soil was taken from 30 sites. CI was obtained using the soil penetrometer and soil classification was conducted using sieve analysis with eight kinds of sieve. The soil was taken on December when is during winter in Korea. There was variation of data including moisture content and CI.

The objective of our study is investigating the effects of the minimum wage on a producer price index (PPI) and selected restaurant menu prices. As an identification strategy, we exploit inter-industrial and inter-regional variations in the share of workers who are affected by the minimum wage. Estimation results show a significant relationship between the share of workers affected by the minimum wage and prices. Specifically, a PPI and selected restaurant menu prices tend to rise by 0.77~1.68% and 0.16~1.86%, respectively as the share of workers affected by the minimum wage increase by 1%p. These estimates imply that during the period of our analysis 0.82~3.01% and 4.45~47.04% of overall changes in a PPI and selected restaurant food prices are associated with the adjustment in the minimum wage.

The F&EI technique is one of the risk assessments with many advantages. It can save time and effort compared to quantitative risk assessment (QRA). By using the evaluation result of this technique, it is possible to check the effectiveness of the investment cost. In addition, a relative risk ranking can be created and used to establish the facility management cycle and to prioritize investment. However, evaluating the target process can be evaluated more than the actual risk since the LCCF, a loss prevention measure, is too limited. In addition, calculating premiums via this method can result in excessive premiums, making it difficult to evaluate the risk precisely. Therefore, new safety guard was added to the LCCF of the F&EI risk assessment with reference to HAZOP and LOPA techniques. Newly added LCCFs are Deflagration arrester, Check valve, SIS, and Vacuum beaker, etc. As a case study, F&EI risk assessment was performed on Acetone storage tank of a API (Active pharmaceutical ingredient) plant to compare actual MPPD. The estimated loss amount was 592,558$ for the existing technique and 563,571$ for the improved technique, which was reduced by about 5% compared to the previous one.This proved that a more precise evaluation is possible and that the efforts for safety at the workplace are reflected in the evaluation results.

An experiment was carried out to investigate the effect of the vinyl pot size and number of plants per pot on the seedling growth. Dry weight per plant, coefficient of variance and dry weight/fresh weight ratio increased as pot size increased, but competitive index, unit productivity and top/root ratio decreased. Dry , weight per plant decreased with increase in number of plants per pot, but coefficient of variability, competitive index and unit productivity increased. Dry weight per plant of the check plot (1 seedling/3.5cm $\times$ 3.5cm pot) showed little difference between 3 plants/4cm x 4cm pot and 5 plants/5cm x 5cm pot. Temporary transplanting of five plants per 5cm $\times$ 5cm pot saved seedbed area and seedbed materials by 60.9% and labor of transplanting by 36.3% as compared with check plot.

Myanmar was successful in increasing its sustainable development index during the three years period from 2018 to 2020. However, the index began to decline since 2021. This study aims to analyze both the success factors and obstacles for sustainable development in Myanmar. Using the search terms 'Myanmar' and 'sustainability', online news items were collected from January 2018 to December 2023 and were examined through text network analysis. The study identified the following success factors that contribute to sustainable development in Myanmar: foreign investments, private companies' participation in the effort, human resource development projects, and the use of new and renewable energy. The inhibition factors for the development efforts identified were: government's coercive/restrictive policies, labor rights violations, and forest degradation. The findings of this study provide useful insights for understanding the current status of sustainability in Myanmar from academic and practical perspectives. The results also present benchmarking information for policy-makers in Myanmar and other similar developing countries that are searching for strategic directions in their sustainable development efforts.

The ICEC (Index of Construction Engineer's Competency) quantifies the competence of construction engineers using such parameters as experience, education, and qualifications and assigns four technical grades (expert, advanced, intermediate, and beginners) to construction engineers according to their scores for the efficient management and loading of technical personnel. However, as of 2020, the seventh year since its implementation, ICEC has shown many problems in its application, unlike its intended purpose. So institutional supplementation is required to provide improvement measures that can cope with the changing labor market environment and complement the current ICEC. Therefore, this study examined the current status of the career management system after the introduction of the ICEC, suggested a career index proportional to the competence of construction engineers from the beginner to the expert level, and developed an effective capability evaluation model I²CEC. The improved model presented in this study provides a means to comprehensively judge the performance, experience, and the professional work abilities of construction management engineers. Furthermore, the results of this study are expected to contribute to the development of efficient manpower and career management systems for enhancing the competitiveness of the domestic construction industry.

The aim of this study was to examine whether health status is different according to employment status and income level in wage-earners. We analyzed wage-earners of 2199 men and 1194 women aged 30-64 years, using data from the 2006 Korean Labor and Income Panel Study(KLIPS). The difference of health status according to employment status and income level was compared with the multiple logistic regression and the standardized concentration index of ill-health. The risk of ill-health was high when waged-earners had low income. The same is true for poor employment status when their employment status was unstable as in manual laborers, irregular workers, temporary, daily workers or part-time workers. furthermore, the wage-earners with lower income and a relatively disadvantageous employment status showed the lowest health status compared to other groups. Ill-health was relatively more concentrated in lower income group and poor employment status. This study identified the existence of health inequality among various employment status of wage-earners. It is suggested that policies that deal with the inequality in social class may have an important impact on the health of the population.
