  • Coffee consumption in Korea has been currently growing every year, and as a result, approximately 0.2 million tons of Spent Coffee Grounds (SCG) are being created every year. SCG, which is waste organic material, is often classified as food waste and an annual amount of 0.27 million ton is discarded while containing moisture and provoking serious environmental issue. Physico-chemical characteristics of SCG were analyzed in this study and medium and long-term growth experiments were conducted in order to evaluate its utilization potential. According to the experiment results, mixing SCG into the previous base material resulted in accelerated germination and growth in the mid-term compared to previous base material alone, despite slower germination or growth in early stage. Especially, it showed lower withering rate and decrease in various symptoms that are caused by nutrition shortage in case of discontinued sprinkling, etc., compared to the previous base material. Hence, while SCG has a feature of hindering early development due to its feature of waste organic material that is rich in nitrogen, its benefit for long-term growth coming its moisturizing ability and supply of organic matter was confirmed in the study. On balance, SCG is believed to be a material that can replace or complement the previous base materials.

  • It is often argued that the parental leave should be extended in order to help employees achieve the balance of work and family life. However, one should be careful in designing the parental leave since there is a tradeoff between the continuity of employment after childbearing and the depreciation of human capital due to the time off the work. The paper investigates whether the parental leave payment introduced in Korea in 2001 helped women's take-up of the leave and employment after giving birth. The results are as follows. First, the increase in the payment indeed raised the female take-up of the leave. Second, women returned to labor market less often after giving birth in the short run, but the size of the effect tends to decrease in the long run. However, the negative effect on returning to the same workplace after the birth remains significant in the long run. Lastly, there is no evidence that the share of women of childbearing age at workplace changed due to the increase in the parental leave payment. Although there is a limitation in that the analysis is based only on the employment covered by the Employment Insurance, these findings imply that the increase in the parental leave payment may not be an effective policy tool for promoting female labor market participation. On the other hand, it should be noted that it is necessary to pay attention to child development as well as female employment as an objective in order to make an overall judgement on the parental leave policy.

  • The purpose of this study is to consider ontology theory and get to forge design and implementation of ontology-based access system which is support to the nutrition and food guide tower of Home Economics textbooks in middle school in order to offer the way of effective learning performance. It offers a model by establishing a nutrition and food guide tower access system based on Protege-2000 framework. This system is on the basis of XML, and it makes possible to work with semantic web, a next generation internet technology, and provides a meaning structure that can be shared in the field of nutrition in order to build up the fundament of knowledge an information system for the mutual operations. A learner can systemize the knowledge through a self-information access and an instructor can also check out the degree of learner's learning-accomplishment and interests, directly putting the access system into the teaching and learning process. In addition, it is supposed that the learner can maintain a balance and healthy life by internalizing his or her knowledge throughout ontology not only in a teaching and learning process but also in a daily life.

  • The effect of dietary calcium levels, 50%, 100%, and 200% of requirement, on iron utilization was evaluated in 30 Sprague-Dawley female rats by use of balance study for 3 weeks. In the results of this study, there were no significant difference in feed intake, body weight gain, hemoglobin level, hematocrit, calcium and iron levels in serum and tissues across the groups supplemented different calcium levels. Calcium content in kidney of high-calcium group was significantly higher than that of other groups. Urinary and fecal calcium excretions increased as the level of dietary calcium was increased. With increasing levels of dietary calcium, daily calcium retention was accelerated, but daily calcium retention rate was diminished. Iron intake was significantly higher in adequate-calcium group than that in low-calcium or high-calcium group. Urinary and fecal iron excretions were significantly lower in low-calcium group than those in adequate-calcium or high-calcium group. Apparent retention and retention rate estimated by intake, urinary and fecal excretions of iron were significantly lower in high-calcium group t]lan those in low-calcium or adequate-calcium group. These results suggest that taking dietary calcium supplements reduce the absorption of dietary iron.

  • The effects of ethanol and dietary protein levels on the calcium and phosphorus metabolism were investigated in 15-week-old male rats. Rats were divided into 4 groups ; control group(16% protein, 16 PC) and 8%(8 PE), 16%(16 PE), and 24% protein groups (24 PE) to which was given 5% ethanol mixed with their drinking water. Body weigh gain, organ weight, hemoglobin content, and hematocrit value were not affected by either ethanol or dietary protein levels. Calcium concentrations in spleen were significantly decreased in the ethanol groups than those in control group. Calcium and Phosphorus levels in femur, serum, liver, kidney, and muscle were normal. Among ethanol treated groups, fecal excretions of calcium were a little more decreased, but urinary excretions, balances and apparent absorption rate of calcium were a little more increased in higher percentage of protein group than lower percentage. Urinary phosphorus excretions in the ethanol treated groups were significantly decreased compared with the control group. Among ethanol treated groups, phosphorus balance and apparent phosphorus absorption rate of 24 PE group were significantly higher than those of 8 PE and 16 PE groups.

  • Oral health is a critical factor for diagnosing overall health, as poor oral health has a negative impact on food intake and results in deterioration of nutritional status. The purpose of this study was to research the needs for food developments for the elderly based on their oral and overall health status. Oral status was significantly associated with self-reported health status, and dry mouth (lack of saliva) especially showed a significant relationship with negative self-perception of both oral and overall health. For both elderly men and women, fish and leafy vegetables were the most preferred side dishes. Bread, rice cake, and beverage-type foods were also preferred for snack development. Disease status of the elderly was significantly related with their preference for food development. For instance, those with diabetes were more likely to ask for anti-diabetic diets. The most important factor for the elderly in choosing food was nutritional balance, and less than 3,000 won was cited as an affordable price. The results could be utilized as basic data to develop foods for the elderly.

  • Each country has set low-carbon green growth to a new growth drive for the future while making various efforts. Accordingly, our country also set green growth to our policy task in top priority throughout our country while initiating various policies. Our country has focused on initiating a few policies in green growth. Our country has focused on the development of green industries to secure our national competitiveness while generating added values in green growth. It is necessary to have studies in initiating policies in balance when we consider that green growth should be initiated through the shift over the whole lifestyle. On the other hand, policies led and driven by the central government have been emphasized. Although the planning and establishment of policies might be said to fall under the central government's main areas, green growth policies can be realized regionally in the end. Considering these circumstances, the coordination in a proper way between the central government and each municipality can also be seen as major characteristics only in our country, which can be hardly seen in other countries. This study aims at developing the initiative strategies in our country's green logistics while analyzing the characteristics of green growth and situations of green logistics initiative, studying the government's policies to support green logistics, reviewing the government's policies for supports, and suggesting alternatives for them.

  • The study is examined to illustrate Korea's status in service trade, including travel deficit, outbound travel market, and inbound travel market. This research will also illustrate what factors generate the growth of travel deficit and suggest some alternatives to solve it even if government notes a steady increase in exports of cultural products and programs and entertainment services, driven by the Korean Wave sweeping across Asia. The study suggested some possible alternatives such as growth of travel balance, improvement of low image on Korean tourism, aggressive participation of government, strengthened role of Korean Tourism Organization(KTO), and appropriate control on overseas studies to lessen an increase of travel deficit. In addition, the study concluded, even if a tourism industry includes a higher multiplier effect, the spontaneous participation intention by Koreans themselves and the strong supports from local governments should be another major successful factors to settle down the travel deficit.

  • As a revision negotiation on the KORUS FTA has become a national pending issue, this study aims to analyze changes in the trade structure of Korean export industry before and after the KORUS FTA. For the analysis, this study used Market Comparative Advantage(MCA) and Intra-industry Trade(IIT) indexes. Results of the analysis are as follows: First, in analyzing the competitive and complementary relationships of export products using the MCA index, it was discovered that Korea has formed an export-oriented complementary relationship with the United States. Second, the results of analysing IIT showed that Korea has made a low-quality vertical IIT with the U.S. in some items while it has usually made a weak IIT with the U.S.. Based on the results above, this study proposes a few policy suggestions in the following areas: Improvement of competitiveness in trade-deficit service sector, achievement of the balance of profit and loss in goods and service sectors through the revision negotiation of the KORUS FTA, enhancement of competitiveness in competitive and comparative disadvantage items, reinforcement of ability to respond to consumption patterns in U.S. market, etc. in export-dominant items, and pursuit of horizontal-vertical division of labor in comparative advantage items and horizontal division of labor in comparative disadvantage items.

  • Objectives : This article reviews a solution preventing the illegal distribution of herbal medicine in common use for food and medicine and risks on public health by conducting safety management of food and medicine. Also, this article would like to contribute to improvement of public health treating diseases in compliance with accurate diagnosis and prescription of Oriental Medicine Doctor("OMD")'s. Methods : An approach in this research can be categorized into two : first, to examine the current administrative situation and problems of herbal medicine in common use for food and medicine based on policy documents of Ministry of Health and Welfare and Korea Food and Drug Adminstration("KFDA") and academic articles of the herbal medicine;second, to find reasonable administrative solutions to solve the problems. Solutions : A solution is to strengthen the management level of herbal medicine in common use for food and medicine by selecting 117 items as target items requiring concentrated management. In case herbal medicine is imported for food, KFDA strengthens the quality management level of herbal medicine by making use of inspection frequency at random, collecting and verifying herbal medicine on the market. However, KFDA decides to maintain current different quality specification system of food and medicine reflecting a civil complaint that quality specification of food and medicine should separately managed according to the purpose of use. Herbal medicine as medicine that is functioned as treating diseases and alleviating symptoms, unlike herbal medicine for food, can cure all kinds of diseases by recovering inner balance of human body, making use of other properties of herbal medicine. Medicine has its own properties. If a doctor uses properties of medicine appropriately, he cures diseases. If a doctor uses herbal medicine inappropriately. he may damage human body. Thus, whether side effects of medicine depend on a doctor who uses herbal medicine. Conclusions : All herbal medicine will be supplied into the market after strict safety control of manufacturers of herbal medicine according to the revised Pharmaceutical Affairs Act, beginning in April, 2012. Thus, people can take safer and more reliable herbal medicine through strengthening safety management of herbal medicine and improving quality and transparency in the distribution system. Herbal medicine should appropriately be prescribed by licensed OMD because herbal medicine is used to treat diseases and alleviate symptoms, unlike herbal medicine for food.
