Alcohol consumption is a major source of health problems, for example, alchol consumption is related to liver diseases. In addition, the social and economic costs related to alcohol consumption are enormous. This study was conducted to evaluate the current status and influencing factors related to the recognition and behavioral intention for both drinking and alcohol-reduction programs. Three effective alcohol-reduction programs of clinic program, mass education, and alliance were considered. To explain the health behavior for drinking and alcohol-reduction programs, a five-stage behavioral intention model was built and 500 questionnaires were completed through a telephone survey. Stages of the model composed of recognition of the programs, past experiences, present drinking status, intention for drinking, and behavioral intention for alcohol-reduction programs. As a result, recognition rates of the programs were low in general, therefore the strategies of education, public relations, and advertisement need to be pursued. The alcohol dependency resulted in the fact that success rate was 30％ although trial rate of alcohol-reducing was 23％. The necessity of alcohol-reduction programs were suggested. In addition, significant factors related to the intention for alcohol-reducing were individual attitude and reluctancy to pay their time and money. An insignificant factor was the attitude to their alcohol-reduction by other people. Behavioral intention rates for alcohol-reducing clinics were 4％, and those for mass education were 8％. There were very low purchase rates for clinic program, mass education, and alliance. In conclusion, evidenced-based and effective alcohol-reduction programs need to be encouraged to drinkers by medical doctors, and the strategies of education, public relations, and advertisement are also recommended. In addition, continuing legal and systematic support for alcohol-reducing would lower the drinking rate and ultimately contribute to the nation's health promotion.

This study examined whether specific coping strategies for the university entrance examination stress are related to high school seniors' depression and whether these strategies moderate the relationship between additional life event stress and depression. A sample of 358 high school seniors reported their level of additional life event stress, coping strategies they were using to handle examination stress, and their levels of depression. Problem-focused coping strategies and affective-regulation coping strategies were found to be related to reduction in depression. And, coping with examination stress was found to be related to depression independent of the level of additional life event stress.

Objectives: The purposes of this study are to refer existing and past domestic and foreign policies and to establish a comprehensive plan to reduce sugar consumption and utilize it as fundamental data to establish and implement relevant policies. Methods: Korean government analyzed domestic and foreign policies and average sugar intake to develop draft of sugar intake reduction plan. Based on the plan, objectives, sections and agendas of the plan were set after taking into account of their feasibility. Results: The policy has three directions: to help sugar intake reduction in all population groups, to create an environment which helps people to make informed decision on lower sugar choices and to lay scientific and statistical foundation for sugar intake reduction plan. The goal is to restrict average sugar intake from processed food to less than 10% of total energy intake per day. Three core strategies are to help reduce intakes of sugar in all population groups, to create an environment which helps people to make informed decision on lower sugar choices and to lay a foundation for sugar intake reduction plan. Each strategies has 2~4 projects. Conclusions: This study is expected to serve as a catalyst for carrying out the first phase of sugar intake reduction plan to help reduce sugar consumption.

The current world wide interest in environmental issues has moved from energy conservation to $CO_2$emission reduction. Recently, according to the increase in demand for water resources, insufficient potable water circumstance is supposed, unless there are corresponding in crease in water conservation and water recycling. This study has attempted to analyze $CO_2$emission reduction by water saving strategies like installation water saving devices, rain water harvesting and grey water system. To do this, this research investigates applicable water conservative strategies by literature review and calculated total water saving. The results show that (1) firstly, the water usage and $CO_2$ emission could be reduced up to 44%, (2) $CO_2$ emission reduction by water saving devices and rainwater harvesting system is about 47.7%, and (3) water usage and $CO_2$ emission reduction by grey water system is about 66%. In the future, this paper will be utilized for water management from the early design stage to maintenance stage of water glutton building.

The cost function consists of the weighting functions concerning the structural responses to be controlled and the controller capability. Therefore, the control efficiency depends on the characteristics of the weighting functions. The objective of this paper is the comparative study of the time domain control strategies of LQR and LQG and the frequency domain strategy of H₂ by setting the equivalent weighting functions to the all control strategies. As a result of analysis, LQR strategy is found to be more efficient than other strategies in terms of the response reduction. but the control force is found to be a little highter. As LQG can compensate the limitation of LQR that all state variables should be identified, LQG is more acceptable algorithm than LQR. Furthermore LQG shows a good performance both in the response reduction and the control force. Finally H₂ algorithm is employed to illustrate the importance of weighting filters considering the frequency characteristics of the response and the controller. It Is shown that the H₂ algorithm is found to be the most effective one for the response control with a little control force having a low frequency band.

Many consumers are concerned about the high levels of salt intake owing to the accompanied risk of chronic diseases. Due to this dietary concern, the food industry has recommended the reduction of salt content in many products. However, the addition of salt to meat products improves their quality and sensory properties, including saltiness, color, juiciness, and texture. Because quality deteriorations could induce decreased sensory scores owing to salt reductions, the challenges involved in improving the quality of reduced-salt meat products have been addressed. During the development of low-salt meat products, it is important to reduce sodium content and address the problems that arise with this reduction. Modified salt, organic acids, amino acids, nucleotides, hydrocolloids, high-pressure, ultrasound, electric pulsed field, and irradiation have been suggested as strategies to replace or reduce sodium content, and sensory scores could be improved by these strategies. Therefore, when developing a low-salt meat product, several perspectives must be considered and the latest technologies that could resolve this problem should be adopted.

Local governments are establishing their own greenhouse gas reduction goal and are playing a important role to respond to climatic changes. However, there are difficulties in quantitative analyses such as estimation of future greenhouse gas emission and computation of reduction potential, which are procedures required to establish mid to long term strategies to realize of low carbon society by each local governments. Also, reduction measures must reflect characteristics of each local government, since the reduction power of each local government can differ according to characteristics of each. In order to establish strategies that reflect characteristics of local governments, types of greenhouse gas emission from cities were classified largely into residential city, commercial city, residential commercial city, agriculture and fishery city, convergence city, and industrial city. As a result of analyzing basic unit of greenhouse gas emission by local government during 2007 in terms of per population, household and GRDP based on the type classification, significant results were deduced for each type. To manage the amount of the national greenhouse gas, reduction measures should be focused on the local governments that emits more than the average of each type's GHG emission.

A new concept termed the Innovative Nuclear Power Plant Building Arrangement (INBA) strategy is a new nuclear power plant building arrangement method which encompasses upfront consideration of more efficient decommissioning. Although existing decommissioning strategies such as immediate dismantling and differed dismantling has the advantage of either early site restoration or radioactive decommissioning waste reduction, the INBA strategy has the advantages of both strategies. In this research paper, the concept and the implementation method of the INBA strategy will be described. Two primary benefits will be further described: (1) early site restoration; and (2) radioactive waste reduction. Several other potential benefits will also be identified. For the estimation of economic benefit, the INBA strategy, with two primary benefits, will be compared with the immediate dismantling strategy. The effect of a short life cycle nuclear power plant in combination with the INBA strategy will be reviewed. Finally, some of the major impediments to the realization of this strategy will be discussed.

The growth rate of international aviation is expected to be higher than that of most industries and the proportion of carbon emissions from the aviation industry will become very significant as the year 2050 approaches. Constraining the growth of this industry is not desirable because it is essential for human welfare as well as the development of related industries. However, reduction of carbon due to aviation is not easy because it is difficult to improve fuel efficiency in a significant way. The ICAO (International Civil Aviation Organization), which is the main organization responsible for handling this problem, developed a program named CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation). The present study analyzes various strategies for countries and airlines to comply with CORSIA using a fuel-efficient system. We conclude that countries should improve their airspace utilization systems, airport facilities, and air navigation systems. Additionally, based on the results of a flight data analysis, airlines should improve their operational efficiency in terms of operations control, flight operation, and maintenance management.
