Objective: This study aimed to introduce Health Impact Assessment using the case of a HIA on 2008 Dream Start Project in Cheongju. Methods: We followed the typical procedure of HIA recommended by the Merseyside Guidelines on HIA. In scoping, the steering committee decided 5 key domains of child health to be assessed: prenatal care, vaccination, nutrition, access to health care, and child abuse and also the methods of collecting the evidence. The HIA appraisal team collected information from various sources including literature, community survey, and focus group interviews. The HIA appraisal team also synthesized the collected information in terms of the nature of health impacts and equity and made recommendations accordingly. Results: Positive impacts were expected in prenatal care, vaccination, and nutrition, while negative impacts were expected in access to health care. The impact of Dream Start on child abuse was uncertain. Several recommendations were made and submitted to the Dream Start team for their consideration. About 2 years later, we found many of them were implemented in 2009 Dream Start project. Conclusion: HIA was found to be applicable and effective to make decision makers in the welfare sector consider health in their work.

Purpose: This study was conducted to suggest a method for financial projection of health insurance expenditures that reflects future changes in demographic structure. Methods: Using data associated with the number of patients and health insurance cost per patient, generalized linear models (GLM) were fitted with demographic explanatory variables. Models were constructed separately for individual medical departments, types of medical service, and types of public health insurance. Goodness-of-fit of most of the applied GLM models was quite satisfactory. By combining estimates of frequency and severity from the constructed models and results of the population projection, total annual health insurance expenditures were projected through year 2060. Results: Expenditures for medical departments associated with diseases that are more frequent in elderly peoples are expected to increase steeply, leading to considerable increases in overall health insurance expenditures. The suggested method can contribute to improvement of the accuracy of financial projection. Conclusion: The overall demands for medical service, medical personnel, and relevant facilities in the future are expected to increase as the proportion of elderly people increases. Application of a more reasonable estimation method reflecting changes in demographic structure will help develop health policies relevant to above mentioned resources.

The method of vitnilcation has various merits. It needs neither seeding nor slow freezing. It can freeze embryo by putting it directly into liquid nitrogen at the indoor temperature to $0^{\circ}C$. The operation process is quite easy. Moreover, higher promise of survival can be expected as there is no physical damage by any lumps of ice with the exception of cells. In Kasal's experiment (1990) using EFS liquid and Kang's experiment (1991) using GFS liquid the ratio of the damaged embryo was only 2-3%. But, the method of vitrification is now on the process of improvement, and the final or united method is not yet established. At the present time, most of the major institutes all over the world are using the traditional freezing method in the preservation of mouse embryo, but it is very likely that the vitrification will prevaIl in the near future considering the various merits of it. Calves can be begotten from the embryo by means of vitriilcated preservation in the cases of cow, rat, and rabbit as well as of mouse. In addition, recent experiments have shown that vitrificated preservation was successful in the case of drosophila embryo which was much bigger than mammalian embryo, which fact tells that this method is expected to be preferably used even in the preservation of living organs in the near future.

This paper defines the common features of synbiotics based on the definition of probiotics and prebiotics, and reviews the effectiveness of synbiotic food. The concept of synbiotics is defined as 'a mixture of prebiotics and probiotics that have a beneficial effect on the host, as a dietary supplement that alters living organisms in the gastrointestinal tract and improves their survival.' Synbiotic food contains ingredients with beneficial microbes that are expected to improve interactions between microbial and useful substances. Synbiotic foods may have anti-cancer and immune system-boosting effects. Improved digestion, healthier bowel movements, and overall increased intestinal health has been reported were reported after increasing the healthy microorganisms within the intestinal tract. In addition, depending on the type of food containing the symbiotic ingredients, more consistent weight control, improvement of cardiovascular health, and lower blood glucose levels may also be expected. Unlike previous studies, this review of synbiotics has shown that it is necessary for synergistic effects to take place among microorganisms and components to be further studied. Further research is needed on the safety and ingestion of microorganisms contained in synbiotics.

Food resources have been supplied more and more by crop land expansion, technological Improvement for higher crop yield, establishment of irrigation system, and input of fertilizers, chemicals and others, to sustain a world population increase currently about 6 billion. Food demand will be significantly increased in the 21st century due to population increases of 90 million per year and more consumption of meat with per capital income increase. But food production increase will be limited by difficulty of crop/irrigation land expansion and small or decreasing effectiveness of fertilizer use. Development of new techniques for higher yield per ha is only one way to meet future food demand increase. Optimistic prospect for food demand/supply balance was reported by FAO until 2010, and IFPRI until 2020. However, Worldwatch Institute warned world food supply will be less than expected demand by 500 million tons of cereal grains in 2030. It is necessary to establish a national plan to meet expected worldwide shortage of food resources in 21 century. What planning should be under taken to meet the upcoming century of food shortage in Korea whose food self-sufficiency rate is only $30{\%}$. It is recommended that (1) keep paddy field area as much as 1,100 thousand ha, (2) expansion of barley and wheat cultivation on all paddy area in winter season, (3) continue development of new technology to get international superiority of food resources produced in Korea, (4) expand nationwide the importance of food security under the current financial crisis encountered In Korea, and for food security in the future unified Korean peninsula.

Current low head and small scale hydroturbines have limitations in the minimum required head and flow rate for efficient operation. This study attempts to develop a new concept hydroturbine which is expected to run efficiently even in very low head and small flow rate, so that the limitations on the conventional small scale hydropower could be alleviated and competition with other alternative energy sources in the economic respect could be attained. A small scale catapillar track- hydroturbine was fabricated and the performance test was carried out in a water tunnel over the head range of H = 0.8 m ~ 1.26 m. The peak turbine efficiency was 41.3% at the speed ratio of 0.6, and the turbine loss was mostly due to the friction at the chain drive used for power transmission from the runner to the shafts. This type of turbine is expected to become competitive when some improvement in the power transmission mechanism is made.
