Accidents are important causes of death and disability in children. They also have enormous financial implications. Young children become an victim of accidents easily because of their physical fragileness and their coping behavior being vulnerable to any actions taken by accidents. Once they have a accident, the children whose not fully developed, suffer from devastating long-term after-effects. Lee, Lee, Kang and Han(1995) reported that ninety percent of accidents can be prevented. But there is no national system to manage, evaluate and analyse the information about child accidents, even though it is necessary for accident prevention policies and health promotion of the general public. The purpose of the study was to determine how often children have accidents and define the accident prevention strategies in children. The investigator conducted a descriptive study by performing the surveys, interviews, and workshops for the 2,458 young children, 10 teachers, and 1,494 parents. The data collection for the study began on September 2000 and completed on April 20, 2001. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics. Among those children, 1,298 children(52.8%) injured from accidents. The children who had accident answered that they injured from traffic accident(27.3%), inside the home(26.3%), on the playground(17.0%), during playtime(13.6%), in the school(5.9%) and food poisoning(7.1%). To define accident prevention strategies for the school children, the parents and the teachers who had a special interest in this topic formed a special task force under the guidance of the investigator. The team was charged to prepare the basis of content materials by identifying the problems, setting standards for the program, prioritizing the process, and selecting the methods of implementation and evaluation. Eight issues and concerns identified by the team were: 1)allowing young children to learn undesirable habits and behaviors that would bother others without knowing; 2) not guarding young children from car accident; 3)unattended accident at playground; 4) considering home places safe; 5)unattended accident at school. These issues were found to be coinciding with the actual child accident cases occurred recent years in Korea. Greater efforts are required to reduce unnecessary deaths and disability from childhood accidents. This study gave a very useful and important data to prepare accident prevention educational program and to prepare accident prevention strategies.
This study aims to examine the quality characteristics of bread by the amount of addition of black garlic powder. there bas been increasingly higher interest in functional foods. According to the results, after analyzing mixograph, of the dough by using mixograph, the bread containing black garlic powder was considered to be most suitable for making bread As for stickiness of the dough with black garlic powder added, the higher black garlic powder was added, the more the bread becomes sticky. BG 6(i.e. bread with 6% of black garlic powder) had the highest fermentation rate for 60-minute fermentation period(i.e. first fermentation). Analysis through crumbScan showed that there were significant differences in crumb fineness between the control and bread with addition of black garlic powder, showing no significant difference by the amount of addition of black garlic powder. As for the volume and specific volume of bread with addition of black garlic powder, the more black garlic powder, the less volume and specific volume. Preference test showed that BG 6 got the best appearance and taste, in overall preference, BG 6 and BG 9(i.e. bread with 9% of black garlic powder) showed the same degree. However, BG 6 is considered the optimum addition of black garlic powder to reduce the production costs in the numerical respect.
In recent years, the growing interest in the health care benefits of sugared-plant fermented enzymes has led to increased consumption. This study investigated the fermentation of sugared-buchu (Leek:sugar, 1:3) by lactic acid bacteria (Lactobacillus acidophilus AML 0422, Lactobacillus brevis HLJ 59, Lactobacillus helveticus AML0410, Lactobacillus plantarium KCTC 13093) and the antibacterial activity, antioxidant activity, and functionality (e.g., anti-hypertensive activity) of the fermented product. The fermented sugared-buchu showed high antibacterial activity against Staphylococcus aureus KCTC 1916, at 31.43 mm, and its total polyphenols, total flavonoid content, and DPPH scavenging activity were 160.8-178 mg/ml, 100-108 mg/ml, and 51.4-58.1%, respectively. DPPH scavenging activity was to that of vitamin C (50 ppm). ACE inhibitory activity was 50.4-67%, depending on the strain of lactic acid bacteria, and the control of sugared-buchu activity was higher than 32.6%. These results suggest that sugared-buchu fermented with lactic acid bacteria has strong antibacterial, antioxidant, and ACE inhibitory activities.
Immunostimulating effects of lactic acid bacteria as biological response modifier is a subject of growing interest, but the knowledge of these focused on some bacteria as Lactobacillus and Bifidobacterium. In this study, we investigated the effects of Pediococcus pentosaceus EROM101 on the immunostimulating and anti-cancer activity in murine model. P. pentosaceus was mainly found in Kimchi and fermented sea food and is facultatively anaerobic, catalase-netative, gram-positive cocci arranged in pairs, tetrads and clusters. The immunostimulating effects of P. pentosaceus EROM101 were evaluated using IgA production assay of Peyer's patch and proliferation assay of exudated immune cells of Balb/C mice fed P. pentosaceus EROM101 for 3 weeks. The macrophage and splenocyte proliferation were enhanced by orally administrated of P. pentosaceus EROM101. Also, IgA production in Peyer's patch increased by P. pentosaceus EROM101. Anti-cancer activity of P. pentosaceus EROM101 was appeared in Sarcoma 180 tumor-bearing ICR mice. However, this bacterium lysate itself appeared to have noncytotoxic substance against Sarcoma 180 cell in vitro. These results suggested that P. pentosaceus EROM101 reinforce immune system and therefore was revealed to be anti-cancer activity in mice.
Diabetic mellitus in an older population is associated with increased basal oxidative stress and free radical accentuated by hyperglycemic challenge. Enhanced free radical in diabetic elderly can cause the oxidative damage and such damage can be protected by antioxidant defense system. It is believed that vitamin C, A and E are the most abundant and effective antioxidants in human plasma. The purpose of this study was to determine the antioxidant status in Korean diabetic elderly using the case-control study. The antioxidant status was examined by determining plasma levels of antioxidant vitamins (vitamin C, A, E, ${\beta}$-carotene), total antioxidant status (TAS) and thiobarbituric acid reactive substance (TBARS) and intakes of vitamin C, A, ${\beta}$-carotene and retiol. Fasting glucose and HbA1c levels and serum lipid profiles (triglyceride (TG), total cholesterol, HDL-cholesterol and LDL-cholesterol) were also determined. Diabetic subjects were 122 elderly persons over 60 years old, visiting public health center, and control subjects were 96 healthy elderly persons living in Ulsan, Korea and they were matched by age, gender, smoking and drinking status. The diabetic and control subjects were divided into sub-groups according to the status of using diet therapy and vitamin supplement. The subjects were interviewed to collect data on their general characteristics, disease history, vitamin supplement, diet therapy and health-related habits by questionnaires. Their dietary intakes were obtained by means of semi-quantitative food frequency questionnaires (SQFFQ). Fasting plasma glucose and HbA1c levels were significantly higher in diabetes than in control subjects, and plasma total cholesterol level of diabetes was not significantly different from that of control subjects. However serum HDL cholesterol level of diabetes was significantly lower and serum TG level of diabetes was significantly higher than those of control group. The average vitamin A and ${\beta}$-carotene intakes of diabetes were significantly higher than those of control subjects. There was no significant difference in plasma vitamin C, ${\beta}$-carotene, and TBARS levels between two groups, but plasma vitamin A, E and TAS levels were significantly higher in diabetes than those in control group. Plasma vitamin A and TAS levels of diabetic subjects using diet therapy were higher than those of control using diet therapy, and plasma vitamin E, ${\beta}$-carotene and TAS levels of diabetic subjects using vitamin supplements were significantly higher than those of controls using vitamin supplements. These results suggested that diabetic mellitus could enhance antioxidant defences against reactive oxygen species and interest in healthy eating such as consumption of more antioxidant nutrients.

In Korea, an olive flounder is very popular fish food item. However, due to the increasing human population, the present catches of the olive flounder may not be sufficient to satisfy the present demand. To increase the supply of the olive flounder, aquaculture has been begun. An interest in the aquaculture of the olive flounder has been increased recently because of its characteristics of good growth and high price in the market, However, the productivity of the olive flounder aquaculture depends on economic inputs such as fuels, facilities, and labor. The rapid growths of the olive flounder aquaculture and the concerns about economic and ecological sustainability have focused peoples attention on the aquaculture industry. In this study, an energy systems model was built to simulate the variation of sustainability on the aquaculture of olive flounder, The results of simulation based on calibration data in 1995 show that olive flounder production yield and asset slowly increase to steady state because of the law of supply and demand. The results of simulation based on the variation of oil price show that the more increase the oil price, the more decrease the olive flounder economic yield and asset. Energy sources required for systems determine the sustainability of systems. Conclusionally, the present systems of the olive flounder aquaculture should be transformed to ecological-recycling systems or ecological engineering systems which depend on renewable resources rather than aquaculture systems which depend on fossil fuels, and be harmonized with the fishing fisheries by the sustainable use of renewable resources in the carrying capacity.

With the development of economy and improving of people's living standards, people dietary needs will be achieved from subsistence to high nutrition and from high nutrition to healthy transformation. Mushroom as a kind of highly nutritious, low fat, rich vitamin food has a great interest among the people. This makes the mushroom into a new sunrise industry and it gradually from pure manual cultivation develops toward the fully automatic factory. In the process of mushroom factory production, regulation of environmental factors directly affects the yield and quality of mushroom. In related to the methods of mushroom cultivation, the recent technologies apply the new technology such as sensors and IT convergence services. And then cultivating mushroom is managed effectively. This paper in order to solve the above problems and construct an effective mushroom growth environment using technology such as humidity sensor construct an environment that can automatically adjust the humidity. This environment has important significance to improve the level of automation mushroom production, increase yield per unit area and quality of mushroom, increase economic efficiency of mushroom production, and enhance the competitiveness of mushroom production.
Our team carried out a new program for public engagement on nanotechnology in Korea. We chose 22 monitors, who majored in science or technology and graduated from universities long time ago. Most of them were married and housewives. This 'focus group' had not only general knowledge about science or technology but also much interest in social activities. The 167 nanoproducts to be monitored were for daily life, e.g. home appliances (washing machine, refrigerator, water purifier, etc), clothing, cosmetics, food, toy, and others. And the period of it was one month. The monitors had a sheet with 10 questions, and filled them out in essay form. All of them submitted 2~3 sheets every weekend to our team. Before monitoring, our team had a meeting for introduction and explanation about the potential risk of nanotechnology as well as benefits from it. Another meeting was held after finishing monitoring to share their experience one another. The main results of the monitoring were as follows: the number of nanoproducts describing both the definition of 'nano' and the size of nanomaterials was just 2 (1.2%) the number of them explaining the technical methods enough was 15 (9/0%) the number of them accounting for the reason of functional improvement enough was 14(8.4%); the number of them doubtful as if there would be exaggeration or false knowledge was 27 (16.2%); the number of them commenting potential hazards to human health or environment was almost zero; the number of them describing about safety certification acceptable was 9 (5.4%). The monitors made a proposal containing recommendation to Government and industry. The contents were as follows: industry should make the manual in detail and correctly, Describe Certificate detailed and correctly, Do research on risk and toxicity continually, Educate employee about nanoproducts at consumer's center; Government should make indication of nanoproducts compulsory, Appoint Certificate Authority and make Certificate Mark guaranteeing the safety on nanoproducts, Make detailed explanation about nanoproducts compulsory.

The growth, reproduction, gametophyte(G)/tetrasporophyte(T) ratio, and diseases of Chondrus ocellatus populations were examined at 3 sites (Samcheok, Youngduk, Pohang) of East coast and at 2 sites (Hakampo, Manripo) of West coast in between July and August, 2013. Average plant lengths were 6.10~9.69 cm and it was minimum at Manripo and maximum at Pohang population. In general, average plant length and weight of C. ocellatus were greater on East coast than West coast populations. The proportion of vegetative plant was between 26.7~66.7 %, and G/T ratio of total plants including vegetative plants after testing resorcinol method was 3:2 on the East coast where is gametophyte dominant area. However, G/T ratio was 1:1 at Hakampo and 1:2.3 at Manripo representing tetrasporophyte dominance. In the present study, Korean C. ocellatus have various diseases (white colour and green colour), an endophytic alga(Ulvella sp.), and many epiphytic macroalgae and diatoms. Healthy C. ocellatus plants were about 20~40 % in summer population and most of plants had disease. Chondrus ocellatus had a filamentous green alga, endophytic Ulvella sp. which was not identified. The endophyte is easily observed in C. crispus growing in Europe and Canada and it is recognised as a pathogen destroying population and reducing yield of C. crispus. Thus more interest and research on the endophytic algae and disease of C. ocellatus are required.

The United Nations Food and Agriculture Organization (FAO) has established the Globally Important Agriculture Heritage Site in 2002, designating the Agricultural Heritages with global value, and carries forward conservation and management. In Korea, the Agricultural Heritage system was adopted to conserve and manage the valuable resources of agricultural space in 2012. Although, the interest in the Agricultural Heritage has been developed, the valuation standards for unique value of the Korea Agricultural Heritage has not been yet established, so discovery and designation of the Agricultural Heritage are at a standstill. Meanwhile, a study from the conceptual viewpoint of the Agricultural Heritage, resources investigation for discovery of the Agricultural Heritage, index development, and a study for conservation and management methods through sightseeing are focused, and a study for the valuation standards about the Korea Agricultural Heritage are not focused. Therefore, the study has analyzed a value of the Korea Agricultural Heritage, and suggested the standards of evaluation a value of the Agricultural Heritage rightly. This study suggested the valuation standards of the Korea Agricultural Heritage used in discovery and designation of the Agricultural Heritage, so prepared a base to conduct the valuation considering the characteristics of the Agricultural Heritage. Such standards will contribute to conservation and management of the Agricultural Heritage in the future.
