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 recent domestic construction market is in a difficult situation due to reduction of the government's SOC budget and new orders from public-sector, and the deterioration of housing supply situation in the private sector etc. In addition, the number of disasters in the construction industry has increased in recent years with 26,570 people (up 5.7% from the previous year) in 2016, unlike other industries that are in a declining trend. As such, the construction industry has unique characteristics and problems such as high industrial accidents rate, abnormal subcontracting structure, excessive working hours and work intensity. As a result, the construction workers have a lot of job stresses. Job stress has been recognized as one of the major causes of industrial accidents and many researches have been conducted on that. However, most of the researches were about the factors that induce job stress and how these factors affect disaster occurrence, job satisfaction, job performance, turnover intentions, and job exhaustion. The purpose of this study is to investigate the effect of positive psychological capital on job stress, which is emerging as a new human resources development paradigm useful in corporate management in order to find ways to reduce job stress. To do this, 347 data collected from construction workers in Daejeon, Sejong, and Chungcheong provinces were analyzed using statistical package(IBM SPSS 22) for basic statistical analysis, reliability analysis, and regression analysis. As a result, positive psychological capital has shown an alleviate effect on job stress. In particular, the higher the optimism, hope, and resiliency of positive psychological capital, the lower the job stress. However, the higher the self - efficacy, the higher the job stress.

The purpose of this study is to suggest production planning model for women's apparel manufacturer, which are relevant to the situation of Korean clothing industry. The research was based on simulation method. The basic model for the simulation was developed based on the empirical data from six production fm. After verifying the basic model, low alternative production plans went through trial run. In order to suggest the application of these alternative production plans for various style numbers and lot sizes, the simulation results were compared in terms of product efficiency and product cost. The four alternative plans were as follows: 1. The first alternative was to spread out work loads among workers in order to resolve bottlenecks in work flow. So this was suited to manufacturers that had constant production without regard to changing seasons. 2. The second alternative was to merge the skirt and trouser production, which require less work load, in one line. In this line, a few machine was justified by production improvement. It was suited to cases which producted various style suits. The third and fourth alternative were using another subcontractor for assembling inner shell garments. These was compatible in manufacturers which had to product more styles and sizes of trousers and skirts than those of upper garments. 3. The third alternative was to reassign the same workers in production line. Thus, production was increased. 4. The fourth alternative was to except two worker in production line, so expenses of worker's wage was decreased. The four alternatives could be one of the cost effective manufacturing plans according to manufacturer situations.

The work-man's Uniform should be coincident with the image of his firm and accounted of the function according s its purpose. We made questions to 404 workers at 8firm in our country through the questionnaire papers to know about a work-man's uniform and researched whether the satisfactory in wearing his uniform had relation with his type of business, grade, carrier, age, marriage, and monthly income. The results of this study is as follows; 1. In the case of wearing the uniform many workers answered they always wore their uniform in the firm. It was shown that the office workers wore their uniform much more than workers in the production department. The longer the time working, the older age, the lower grade of school career are, he more workers wear. the order of the importance for he uniform was the function, the symbol, the originality, and the fashion. The longer their career in the firm was, the more important the function of their uniform was. 2. The order of dirty pat in taking care of the uniform was cuffs, color, the front of part in an upper garment and below the knee, the hip in pants It was very easy for the workers in the experts, or administrators and office workers than others to be dirty in the cuffs part of the uniform. Worn part of the uniform showed highest cuffs in an upper garment and a zipper in pants. The order of cleaning the uniform was washing by water, no ironing, and cleaning in their house.

Objectives : A survey was conducted to investigate oral health belief and education awareness of oral health of workers in the workplace and to obtain the basic data necessary to promote their oral health and design an oral health education program. Methods : This study conducted a self-administered survey. Results : The following conclusion was made. For oral health beliefs based on the type of work that the workers did, workers in production and technical services had more benefits than those in other fields(security, guard, etc.), and workers on night duty had more oral health hygiene problems than that of regular day-time workers. The longer the period of service was, the more sensitive and serious the workers were and the less beneficial the work was; workers working for eight hours or less had higher levels of importance than those working for ten hours. They were well aware of the need for oral health education but were less aware of the need for an oral health room. Conclusions : It is necessary to emphasize oral health beliefs when developing an oral health education program that promotes oral health for workers in the workplace. If an oral health education program attempts to reflect the concerns of workers in the workplace and provides preferred contents and methods on oral health education, the program is expected to promote the active and positive participation of the workers.

Opening of a new economic paradigm in the transition to the Fourth Industrial Revolution, the human capital engaged in industry or occupation based on individual creativity is called creative workers. The workers of this kind regards 'quality of place', known as amenity, as an important factor in choosing a residential area. This paper analyzes how the effect of city amenity influences on residential preference of creative workers in comparison with production workers. First, as of 2014, the total number of creative workers are 5.73 million (23.2% of the total workforce), and more than half (58.6%) are concentrated in Seoul and Gyeonggi area. Second, the excess residence rate of the creative workers (number of residents/number of jobs) is high in metropolitan areas. Third, when comparing with workers in productions sector, the selection of residence location for creative workers are significantly influenced by certain city amenities such as education. The outcome of analysis is expect to be utilized as a preliminary work for making policies which promotes number of creative workers at the regional level.

The purpose of this study is to identify factors influencing fish production of shallow-sea aquaculture in South Korea. This study employed the two-way fixed effect and random effect models based on the panel models and also the difference between GMM and system GMM models based on the dynamic panel models using the amount of fish farming production, the number of stocked fry, the number of cultured fish, the amount of inputted feed, the farming area, the number of workers, and the sales price data from 2010 to 2017. First, the two-way fixed effect model of the panel models was selected by panel characteristics, time characteristics and Hausman tests and also the model was statistically significant. As a result of the two-way fixed effect model, the number of stocked fry, the amount of inputted feed, and the number of workers were identified as factors that increase the fish production of shallow-sea aquaculture. However, the number of cultured fish and the sales price were analyzed as factors that reduce the fish production of shallow-sea aquaculture. Second, the system GMM model of the dynamic panel models was selected by Hansen test and Arellano-Bond test in order to identify whether or not the over-discrimination condition is appropriate. Based on the system GMM model, the number of stocked fry, the amount of inputted feed, the number of workers in this year and 1 year ago, the number of cultured fish 2 years ago, and the sale price 3 years ago were analyzed as factors that increase the fish production of shallow-sea aquaculture. However, the amount of fish farming production 1, 2, 3 years ago, the farming area in this year, and the number of cultured fish in this year and 1 year ago were identified as factors that reduce the fish production of shallow-sea aquaculture. In conclusion, this study suggests that it is desirable to control the amount of stocked fry rather than to expand the farming area for fish farming in shallow-sea aquaculture, so as to keep the sale price at a certain level by maintaining the appropriate amount of fish production.

Objectives: It has been pointed out that there are problems in handling and managing chemicals due to trade secrets of Material Safety Data Sheet(MSDS). To date, some company intentionally leave out of several parts and use an inaccurate expression in MSDS. In particular, with the result of the inspection of the government and labour community, it is required that the 2nd section in MSDS included the composition and information on ingredients has to be provided with comprehensive expression to secure more reliability. Methods: Therefore, this study is aimed: 1) to recognize the current status of trade secrets of MSDS in workplaces with both domestic manufacturers of chemical products and multinational corporations; 2) to make contributions to prevention of the industrial accidents by providing the accurate information of MSDS; 3) to improve the risk communication system related with chemicals; 4) to impress workers on the importance of right of known for MSDS. With the result we analyzed the status of trade secrets in MSDS in 73 companies, such as petrochemistry production, paint production, metal processing oil production, detergent production, and international company related with chemicals, we have found that 38,150 (45.5%) have the trade secrets parts in the total number of 83,832 in MSDS. Also, based on the 288 MSDS gathered by the Occupational Safety and Health Research Institute (OSHRI) from 2005 to 2009, 41.7% of the MSDS are classified into the trade secrets. Conclusions: Therefore, to procure an assurance system of MSDS, we suggest that a MSDS picking up and checking system be legislated in the Occupational Safety and Health Act to protect workers from the unidentified chemical hazards due to the secret trade of MSDS.

To increase the productivity and efficiency of an enterprise, all relevant product information should be provided to shop floor workers timely and in a unified form because shop floor workers are final consumers of most accumulated information generated from various departments of an enterprise. but, most existing enterprise information systems have an emphasis upon providing design/manufacturing information to office workers. Proposed in this study is a development of integrated design/manufacturing information system focused system, the function required for shop floor activities. For developing integrated information system, the functional required for shop floor are identified and analyzed. Based on the extracted functional requirements, object-oriented system design and implementation is conducted. By using this system, shop floor workers can refer to all relevant information necessary to their work easily and in a integrated form.
