  • Purpose: This paper introduces new 2-of-3 main and supplementary runs rules to increase the performance of the classical $\bar{X}$ control chart for detecting small process shifts. Methods: The proposed runs rules are compared with other competitive runs rules by numerical experiments. Nonlinear optimization problem to minimize the out-of-control ARL at a specified shift of process mean for determining action and warning limits at a time is formulated and a procedure to find two limits is illustrated with a numerical example. Results: The proposed 2-of-3 main and supplementary runs rules demonstrate an improved performance over other runs rules in detecting a sudden shift of process mean by simultaneous changes of mean and standard deviation. Conclusion: To increase the performance in the detection of small to moderate shifts, the proposed runs rules will be used with $\bar{X}$ control charts.

  • Reducing fishing capacity is one of current issues in the international fisheries. This is because that increased fishing capacity has caused not only fish stocks to be depleted, but also additional fishing costs to be incurred, which resulted in reduction of economically viability of fisheries. For this reason, FAO adopted the International Plan of Action for the Management of Fishing Capacity' in 1999 and recommended member countries to estimate fishing capacity and to implement the policy to reduce fishing capacity. This study is aimed to measure fishing capacity of the Large Purse Seines Fishery that is one of offshore fisheries in Korea using both Peak - to - Peak Analysis and Data Envelopment Analysis in order to provide a policy information for preparation of domestic plan of action for the management of fishing capacity. The results of PTP Analysis were almost similar to those of DEA Analysis. The DEA results showed that the capacity utilization in 2004 was about 75%, it was obvious the capacity did not utilize enough. The sensitivity analysis on DEA results indicated that 24% of the number of ships, 26% of the tonnages, or 29% of the horse powers should be reduced if the present catch remained. In addition, if the catch remains at the MSY base level of large purse seines, the analysis suggested that the number of ships, tonnages and horse powers should be reduced by 15%, 18%, and 21% respectively.

  • There exists dead zone from the aspects of health equity and health medical equity for maritime personnel. They could not have been benefited from disease prevention and health promotion in comparison with shore personnel due to the restricted medical accessibility caused by long voyage ship operation. Furthermore, the system of health management and medical assistance for maritime personnel is insufficient, the continuous health monitoring system does not exist, nor health diagnosis system, maritime industrial accidents and occupational disease control systems are adequate. The International Maritime Organization and the International Labour Organization recommend their Member Governments to take necessary measures in the management of seafarers' health and diseases through conducting continuous and systematic investigation. Thus, this study intends to propose action strategy and tasks for introducing marine telemedicine system aiming to provide seafarers with health management service for the years to come. The conclusions of this study can be given as follows. First, it is required that a systematic medical service system needs to be provided to promote seafarers' health. Second it is recommended to establish the marine telemedicine system incorporating U-Health technology. Third, it is necessary to revise the relevant laws and regulations to introduce the marine telemedicine system. Fourth, it is also necessary to provide various assistance system at the national level in the furtherance of global marketing of marine telemedicine system.

  • In this research, we tried to develop the application method to water management and treatment using toxicity test method. When we measure the toxicity of environmental samples, we have to decide whether we take some countermeasures to reduce the toxicity or not. The first issue is how to set these action levels in each bioassays. A new idea was attempted to authorize indirect approach of each bioassays through the response characteristics against mixture of chemicals in water quality standard. The significant response in the cell-growth-inhibition bioassay was detected for standards-mixture(STDs). For acute toxicity assay, STDs-based implicit correlation between risks to humans and bioassay data showed a rational approach to set action levels in practical management. A simple model was proposed to describe and predict the changes in the total toxicity based on the concentrations of toxic-controlling chemicals during the ozonation of landfill leachates. On the basis of this simple model, toxicity reduction was predicted for pre-aggregation treatment before ozonation and ozone concentration during the ozonation. The method proposed in this study would be useful in optimizing water treatment processes and their running conditions in terms of the toxicity reduction efficacy.

  • The study investigates the challenge of knowledge maintenance in the KMSs. Knowledge pieces are the embodiment of structures in an organization and need to be modified tuned to environmental change over time. Since the change of knowledge in the KMS is not made automatically, it requires user's active participation which is called maintenance action. This study shows that users are not voluntary in taking maintenance action with empirical data based upon knowledge pieces that are already established in the KMS. This article shows that the intention of maintaining KMS is negatively influenced by KM-related culture, organizational culture and the authority of knowledge piece rather than the organizational demography. An organizational culture has an influence directly upon the intention of maintaining knowledge but influence upon KM-related culture or the authority of knowledge piece, the influence indirectly related to the intention of maintaining knowledge. It can be argued that the organizational demography have only meager influence upon the intention of maintaining knowledge only by KM-related culture. This research has the implication that what factors are to be considered in maintaining knowledge pieces over time for the organization managers.

  • Control Banding (CB) strategies to prevent work-related illness and injury for 2.5 billion workers without access to health and safety professionals has grown exponentially this last decade. CB originates from the pharmaceutical industry to control active pharmaceutical ingredients without a complete toxicological basis and therefore no occupational exposure limits. CB applications have broadened into chemicals in general - including new emerging risks like nanomaterials and recently into ergonomics and injury prevention. CB is an action-oriented qualitative risk assessment strategy offering solutions and control measures to users through "toolkits". Chemical CB toolkits are user-friendly approaches used to achieve workplace controls in the absence of firm toxicological and quantitative exposure information. The model (technical) validation of these toolkits is well described, however firm operational analyses (implementation aspects) are lacking. Consequentially, it is often not known if toolkit use leads to successful interventions at individual workplaces. This might lead to virtual safe workplaces without knowing if workers are truly protected. Upcoming international strategies from the World Health Organization Collaborating Centers request assistance in developing and evaluating action-oriented procedures for workplace risk assessment and control. It is expected that to fulfill this strategy's goals, CB approaches will continue its important growth in protecting workers.

  • This study was a qualitative investigation of the process of adaptation of nutrition education programs by marriage immigrant women who completed education programs for training of food citizen leaders. Focus group interviews of seven marriage immigrant women from Vietnam, China, Mongolia and Russia were conducted and analyzed based on the Normalization Process Theory (NPT). Participants were aware of the purpose of the education program (coherence) and their confidence in organizing and reconstructing the knowledge of nutrition was increased after education (reflexive monitoring). However, they had difficulties attending long-term education programs (cognitive participation) and overcoming language barriers (collective action). Although the program was beneficial for the participants in that they could apply acquired nutrition knowledge to their everyday life as food citizen leaders, the continuous monitoring and feed-back system (management), customized application, and consideration of personal and social factors need to be developed and facilitated. In addition, various programs targeting marriage immigrant women may increase economic independence of these women. The NPT proved beneficial in conceptualizing the barriers and facilitators to implementing nutrition education. The successful implementation of nutrition intervention needs special support to overcome barriers to cognitive participation and collective action.
