The objective of this study was to provide information regarding trends of rice consumption of Korean adults based on different meal types. Respondent reports 24-hour recall data from the Korean National Health and Nutrition Examination Survey were used to assess daily rice consumption and intake ratios of rice for different meal types and places of preparation. Rice intake had gradually decreased from 224.6 g in 1998 to 190 g in 2001 and to 179.4 g in 2005. The rice consumption of Korean adults decreased every year in all ages for all places of meal preparation in 2001 and 2005 compare to 1998. Analysis for each meal type showed that rice intake at breakfast had not considerably changed, but rice intake had decreased at lunch and dinner. While the rice consumption ratio at lunch and dinner decreased, it also decreased or did not change at snack times except for the 19-29 age groups. All the age groups revealed comparable change in the analysis for meal types. There was some diversity between all age divisions in daily rice intake depending on place of meal preparation. The rice consumption by place of meal preparation was generally highest at home, lowest at other places, but it decreased in all places. The rice consumption at home was highest in the over 50 age group, lowest in the 20-30 age group. These changes seem to be related to food intake patterns of rice and substitutional foods in the diets and development regarding socio-economic status. So the need for further study on differences in rice intake based on socioeconomic levels and age group are indicated.

The continuing pace of technological change and the trend toward larger and faster ships is evident as shipping lines compete in seeking economies of scale in the global market and ports. become increasingly reliant on sophisticated equipment. Across the Asia and Pacific region some of the worlds most modern container ships are calling at an extensive network of mainline and feeder ports. This paper shows that during the period from 1999 to 2011, Asian container trade is expected to continue to increase more rapidly than the world average, i.e., 7.2 per cent per annum compared with the world average of 6.3 per cent. It is forecast that the total volumes of international containers handled at the ports in Asia and the Pacific will increase at an average growth rate of 7,2 per cent per annum. In order to handle the anticipated port container traffic in 2011, new container berths are required in nearly every country in the Asia and the Pacific region. This will entail very significant capital investment requirements. If countries in the UNESCAP region are to position their ports to meet the challenges of the next decade, there is an urgent need to implement more robust strategies to address important issues including prioritisation of port development projects, promotion of private sector participation in ports, emphasis on productivity and preparation for intermodal integration and logistics growth.

This study was conducted on 878 retired women in their 50s and 60s across the country using the 7th data from the National Pension Service's KReiS. We used SPSS WIN 18.0, and the analysis results are as follows. First, there were many highly educated people in their 50s or older and those in their 60s and undereducated. Second, families in their 50s had the largest number of members with more than three, while households in their 60s had the largest number of two. Third, both age groups chose themselves and their spouses as responsibilities for preparing for retirement. In addition, more people in their 60s chose the government as their responsibility for preparing for retirement than in their 50s. Both people in their 50s and 60s say they are "not prepared" to prepare for retirement expenses, raising concerns about elderly poverty. Fourth, economic strength, health, and medical care were important for retirement in both age groups as part of their preparations for retirement, and they chose economic strength, health, medical care and job as the things to do in society. Fifth, both people in their 50s and 60s have very low public and private pension subscription rates, requiring special attention from the government and society to their old age. Judging from the above results, both women in their 50s and 60s have retired, but preparations for retirement are very insufficient. Therefore, the government and society need to strengthen the public pension system and create jobs for the elderly.

This paper makes a theoretical contribution by providing clear and detailed derivation of economic agents' decision problems including elastic labor supply in Gertler's overlapping generation (OLG) model. We apply the model to the Korean economy by calibration based on Korean economic data. It also analyzes the impact of current social issues such as aging and extension of retirement age, on the Korean economy in a long-run equilibrium. Subsequently, we also discuss the implications of the analysis. Aging has prolonged the period of retirement; therefore, population structure changes by the increase in the proportion of retirees, the total consumption-to-GDP ratio decreases, and capital stock increases due to reduced propensity to consume out of wealth in preparation for an individual's retirement life. The implementation of retirement age extension increases the proportion of retirees relatively less and alleviates fluctuations in labor supply and the share of financial assets for both economic agents. However, the decrements in consumption-to-GDP ratio is larger than before, and this leads to a larger rise in the capital stock compared to when there is only an aging effect.

As the supply and demand of pork has become a significant concern in Korea, controlling it has become a critical challenge for the industry. However, compared to the demand for pork, which has relatively stable consumption, it is not easy to maintain a stable supply. As the preparation of measures for a supply-demand crisis response and supply control in the pig industry has emerged as an important task, it has become necessary to establish a stable supply model and create an appropriate manual. In this study, a pork supply prediction model is constructed using reported data from the pig traceability system. Based on the derived results, a method for determining the supply-demand crisis stage using a statistical approach was proposed. From the results of the analysis, working days, African swine fever, heat wave, and Covid-19 were shown to affect the number of pigs graded in the market. A test of the performance of the model showed that both in-sample error rate and out-sample error rate were between 0.3 - 7.6%, indicating a high level of predictive power. Applying the forecast, the distribution of the confidence interval of the predicted value was established, and the supply crisis stage was identified, evaluating supply-demand conditions.

As the number of scaled-up ranches increased and agile responses to market changes became possible, decision-making by Hanwoo cattle farms also began to affect short-term shipments. Considering the changing environment of the Hanwoo supply market and the response speed of producers, it is necessary quickly to grasp the forecast ahead of time and to respond accordingly in an effort to stabilize supply and demand in the Hanwoo market. In this study, short-term forecasting model centered on the supply of Hanwoo was established. The analysis conducted here indicates that the slaughter of Hanwoo males increases by 0.248 as the number of beef cattle raised over 29 months of age in the previous month increases by one, and 0.764 Hanwoo females were slaughtered under average conditions for every Hanwoo male slaughtered. With regard to time, the slaughtering of Hanwoo was higher in January and August, which are months known for holiday food preparation activities for the New Year and Chuseok in Korea, respectively. Simulations indicated that errors were within 10% in all simulations performed through the Hanwoo supply model. Accordingly, it is considered that the estimation results from the supply model devised in this study are reliable and that the model has good structural stability.

This study, based on a health belief model, examines how baby boomers perceive health and how they are financially preparing for future medical expenses. In addition, the study analyzes which factors influence baby boomers' preparation behaviors for future medical expenses and their perceived sufficiency of the preparation for medical expenses. Through such activities, this study examines baby boomers' current preparation status for future medical expenses, and based on this outcome, will turn the attention of individuals and society toward becoming more concerned with health and increasing health expectancy. For this study, an online survey was conducted targeted at men and women who were born between 1955 and 1963 and live nationwide, and its resultant data were collected. After conducting a 15-day survey in November 2011, a total of 418 questionnaire responses were used for the final analysis. The major findings of this study and their implications are as follows: First, baby boomers' health beliefs and their perceptions of health identified by subjective health conditions were very positive. Second, while there were some partial differences in the influencing factors, health beliefs and perceived health influenced the sufficiency of future medical expenses in the three groups, which were segmented according to how they prepare for future medical expenses-insurance-based, pension-based, and insufficiently prepared groups. Third, the baby boomers selected the national health insurance as the primary means of preparing for post-retirement medical expenses, and backed it up with private health insurance or the national pension. In addition, when baby boomers' perceived sufficiency of future medical expenses were examined, 57.6% of the respondents expressed that their old-age medical expenses were not sufficient. Fourth, in terms of baby boomers' preparation behaviors for future medical expenses, it was revealed that as one recognizes old-age health more seriously, he/she has a higher chance of using insurance and lower chance of using a pension to prepare for medical expenses. Fifth, regarding baby boomers' sufficiency of preparations for future medical expenses, economic factors such as total assets, the sufficiency of retirement assets, and the number of insurance policies, as well as health perceptions, including health beliefs and subjective health conditions, were important influencing factors.
