Importance of the work-related musculoskeletal disorders(WMSDs) has been increasing in the manufacturing industry such as the domestic shipbuilding industry and car industry. Recently, companies have implemented the risk factor investigation due to the amendment of the industrial safety and health law in 2003. At the same time, some large companies have introduced and implemented an ergonomics program for WMSDs. Yet, until now a study of the effect and management of the ergonomics program has not been conducted. In 2005, we audited an ergonomics program in a domestic shipbuilding company four times for 9-month period. The company implemented an ergonomics program from 2003 to 2005. From the investigation, this paper reveals the effects and problems of the ergonomics program implemented by the company and presents methods for its improvement. The findings described in this paper will help the companies to implement their ergonomics program for WMSDs in the future.

Since IMO has discussed the effectuation of the EEDI, EEOI and SEEMP, each country, shipping company, shipbuilding company and research institute have been requested to prepare the design, construction and operation of the efficient ship. From the shipbuilding company's point of view, it was necessary to develop a method based on the maneuvering equations of motion in a bid to estimate the EEOI considering the design, model test results and the calculation results of the ship. In this paper, the estimation method of RPM, power and fuel consumption proposed in the previous research was developed to construct a framework that helps in the estimation of the EEOI. It was possible to estimate the EEOI from the estimated ship speed (distance), LNG cargo mass, fuel consumptions and emission factors according to the type of fuel. The rapid increase of the evaluated EEOI was observed when the LNGC with ME-GI engine executing the course changed with a large difference. This prompted the comparison of the type of fuel on the estimated EEOI by considering HFO, LNG fuel and MGO properties.

In recent years, Korea's shipbuilding industry have expanded its business into offshore plant. These changes are increasing the interest on job stress in shipbuilding industry. The purpose of this study is to investigate the differences of job stressors between white and blue-collar workers. The survey was using Korean Occupational Stress Scale(KOSS) questionnaire and was administered to 8,080 workers of large shipyard company. As a result of the survey, compared with the median score of Korean workers, job stress level of shipyard company workers was low. However, seven categories of KOSS, except for job demand showed higher stress levels of blue-collar workers than white-collar workers. The overall stress level of shipyard company workers is low, however, it is important to find stressors by considering the type of work, working period etc., through a detailed analysis of KOSS 8-categories. The results of this study may be helpful to identify the level of stress and to establish preventive measures in Shipyard Company.

Concerning general information about the subjects who participated in the research, gender was possessed 94.8% by men and 5.2% by women. Age was the largest in 31~40 years old with 44.2%. Marital status was the largest in the married with 64.5%. It was the largest in under high school graduate with 71.9% for academic background, in 2,000,000 won~3,000,000 won with 49.0% for monthly family income, and in cooking with 33.9% for work field. 2. Research subjects' toothbrushing time was indicated to be the largest in after having breakfast. It was indicated to be twice a day with 41.3% for toothbrushing frequency. 90.3% of the respondents are not using auxiliary oral hygiene devices. 3. Recognition on periodontal health status was found larger in workers whose response was that their own periodontal health status is 'healthy' than workers who responded that their status is 'not healthy.' Workers, who don't have subjective symptom on periodontal status, were indicated to be larger. 4. Ratio of subjects with tooth scaling experience accounted for 59.7%. The ratio of tooth scaling experience was indicated to be different depending on academic background and monthly family income. Conclusions : Academic credential, monthly family income and the line of work were identified as the main factors to affect oral health care of the shipbuilding workers. Oral health education and dynamic implementation of corporate oral health promotion which are designed to meet the needs of workers are required.

Work-related musculoskeletal disorders (WMSDs) have become a hot issue in the Korean workplace for the past several years. So many manufacturing companies have tried to improve the work environments for the control and the prevention of the WMSDs. This study investigates the relation between WMSDs and job stress from 965 workers in a shipbuilding company by questionnaire analysis. The seven job stress factors which are job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The prevalence of musculoskeletal disorders symptoms were 12.9%. The analysis showed that job stress by job autonomy was higher than that by job stress factor. WMSDs were associated with job requirement, organizational system, unfair compensation and workplace culture. The results could be used to design the management program for the reduction of job stress.

Objective: The purpose of this study is to draw the accident prevention model using the signal detection theory, and to implement accident prevention program, based on a health promotion and support activities in a shipbuilding company. Background: Workers' health management is perceived important from the human resource management perspective, as well as from the personal perspective. Method: This study developed an accident prevention model by analyzing the correlation between 704 workers' health examination variables, and reviewed the verification of the model through a follow-up survey on the control variables and status of hazards targeting 650 workers for four years from 2007 to 2010. Also, a health promotion program was implemented targeting a production division to improve alcohol habits, smoking, musculoskeletal pain complaints and hearing control indices, which are the control variables of the model. Results: As a result of four years' implementation, the following effects were obtained: the days away from work fell 87.5%, and accident rate dropped 71.5% in 2010, respectively, compared to 2006, before the activity was implemented. Conclusion: This study shows that the accident prevention activities based on workers' health promotion activities are effective to prevent industrial accidents and injuries. Application: The research findings will serve as a practical guideline for establishing preventive measures in the shipbuilding company.

As the largest shipbuilding company in the world and the leader in the Korean merchant shipbuilding industry, Hyundai Heavy Industries is currently struggling to carry out intensive productivity improvement efforts in order to be the global merchant shipbuilding market leader by surpassing in the competition with Japan and being free from the defiance of China armed with very cheap labor costs. This paper introduces the academy-and-industry collaborative project, a part of the productivity improvement efforts, which has conducted on the steel stockyard operations. As a pilot project that researches for the way of improving the stockyard operations and ignites further projects on the stockyard operations, the project defined the stockyard operations, measured current situations, and analyzed management dilemmas. In addition, the project developed the steel stockyard operations simulator. Besides that the simulator is used by the operations manager who has heavily relied on his work-experienced intuition when making decisions, this paper expects that further projects on the stockyard operations utilize the simulator for their own purposes.

Shipbuilding is a typical 'build to order' industry. It has a business model that generates revenues from building various ships and offshore products in accordance with owner's requirements at each production stage. Under uncertainty in shipping market, it is very essential for the shipbuilder to prepare the fast and competitive decision for product portfolio strategy in order to maximize contribution margin by exploiting production facilities and constraints. In this study, we introduce the unique decision supporting methodology for the optimal product portfolio sets based on Theory of Constraints(TOC). This methodology is established by adopting the concept of Drum Buffer Rope(DBR) in constraints planning and Throughput Accounting (TA) in management accounting of TOC. In addition, Decision Supporting System(DSS) is implemented. This DSS system provides a throughput estimator with reflecting the cost structure of shipbuilding industry and a resource simulator built on heuristic algorithms to operate major constraint-resources in shipyard such as dock, quay and pre-erection area etc. Several examples are presented to show that the proposed methodology and system can effectively support the strategic decision-making process of a global shipbuilding company.

기업들이 저원가와 높은 품질을 동시에 추구하게 됨에 따라 제품 아키텍처 기반 경쟁은 기업 전략의 중요한 일부가 되었다. 본 연구는 한 중 조선 산업(LNGC)분야 대표기업의 제품 아키텍처와 조직역량을 비교 분석하여 그들이 어떻게 혁신성과를 이루어 냈는지 고찰하였다. 그 결과, 한국기업은 동력계열의 연구개발에 있어 FGSS(Fuel gas supply system), PRS(Partial Re-liquefaction System)와 같이 에너지 효율을 개선하는 장치를 자체 개발하여 기존엔진에 추가하고, 선체 무게를 경량화 하는 등 다양한 미세조정 노력을 통해 우수한 성능을 가지게 하였다. 이는 우수한 연구조직 역량과 현장과의 긴밀한 협업을 통해 실현되었으며, 고부가가치선의 높은 매출로 이어질 수 있었다. 반면 중국 기업은 설계 및 연구개발의 편의성에 집중하여, 기존의 부품에 대한 미세조정 노력을 소홀히 했고 그 결과 동일한 부품을 사용하고도 한국의 선박에 비해 7-10% 낮은 연비 효율을 지닌 것으로 나타났다.
