Ginseng in Korea has not only the big production value but also till a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using 4P's(product, place, promotion and price). The main results are as follows. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable.
Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, world-wide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs. The group researched all articles and major foreign CPGs published in English until December 2015 using several search engines. Based on these articles, levels of evidence and grades of recommendations were determined by our society as well as by other related Quality Control Committees from neurointervention, neurology and rehabilitation medicine. The Korean version of the CPGs for aSAHs includes risk factors, diagnosis, initial management, medical and surgical management to prevent rebleeding, management of delayed cerebral ischemia and vasospasm, treatment of hydrocephalus, treatment of medical complications and early rehabilitation. The CPGs are not the absolute standard but are the present reference as the evidence is still incomplete, each environment of clinical practice is different, and there is a high probability of variation in the current recommendations. The CPGs will be useful in the fields of clinical practice and research.
Objective : In this study, the Mindfulness Based Stress Reduction (MBSR) program was applied to patients presenting with depression and anxiety after surgery from spontaneous subarachnoid hemorrhage (SAH) and the effects were assessed. Methods : The subjects were patients admitted for cerebral aneurysm rupture and treated by means of surgery from March to December, 2007. More than 6 months had passed after surgery, without any special lesions showing up on computed tomography (CT), and the Glasgow outcome scale (GOS) was 5 points. Among patients with anxiety and depression symptoms, 11 patients completed the program. The MBSR program was conducted once a week, 2.5 hours each, for 8 weeks. The evaluation criteria were : 1) the Beck Depression Inventory (BDI): it measures the type and level of depression, 2) the State-Trait Anxiety Inventory : the anxiety state of normal adults without mental disorder, and 3) Heart Rate Variability (HRV) : the influence of the autonomous nervous system on the sinoarterial node varies continuously in response to the change of the internal/external environment. Results : The BDI value was decreased from 18.5 ${\pm}$ 10.9 to 9.5 ${\pm}$ 7.1 (p = 0.013) : it was statistically significant, and the depression level of patients was lowered. The state anxiety was decreased from 51.3 ${\pm}$ 13.9 to 42.3 ${\pm}$ 15.2; the trait anxiety was reduced from 50.9 ${\pm}$ 12.3 to 41.3 ${\pm}$ 12.8, and a borderline significant difference was shown (p = 0.091, p = 0.056). In other words, after the treatment, although it was not statistically significant, a decreased tendency in anxiety was shown. In the HRV measurement, standard deviation normal to normal (SDNN), square root of the square root of the mean sum of squared differences between adjacent normal to normal intervals (RMSSD), and total power (TP) showed significant increase, Physical Stress Index (PSI) showed a significant reduction, and thus an improvement in the homeostatic control mechanism of the autonomic nervous system was ween. Conclusion : The MBSR program was applied to the patients showing anxiety and depression reaction after SAH treatment, and a reduction in depression symptoms and physiological reactions were observed. The application of the MBSR program may be considered as a new tool in improving the quality of life for patients after surgery.

Recently, as there has been growing demand for aesthetic quality in structural materials, the development of excellent color cement concrete having good coloration properties has become a requirement. This study is designed to analyze the basic physical properties of mortar and the properties of keeping the coloration under an ultraviolet ray accelerated weathering test environment according to changes in the mixing ratio between carbon black and iron oxide used as colorants. The test results show that the use of carbon black and iron oxide reduces the initial flow by 6.3~17.2 % and the air content by 3.5~31.5 % but increases the unit volume weight by 3.4~5.5 %, compared to ordinary Portland cement (OPC). In addition, the study shows that the addition of iron oxide increases the self drying shrinkage. So, caution needs to be taken on the workability of the concrete. The brightness value L⁎ represented by black showed the most excellent black colour when carbon black 3 % and iron oxide 5 % are added. According to UV accelerated weatherproof test, the brightness value L⁎ was found to increase in all experiment specimens by 4.28~11.97 %, and the color change by UV was found to be higher for the case where carbon black colorant was not used. Therefore, in terms of color revelation characteristics, the case using carbon black 3 % and iron oxide 5 % was found to show the best black color.
The purpose of this study is to evaluate the importance and performance of the educational laboratory facilities for culinary practice. The questionnaire was distributed to 100 students enrolled in the culinary arts department at Y University located in Chung-buk province, and a total of 71 usable, completed questionnaires were received for the research. Collected data was statistically analyzed using the SPSS 10.0 Windows version, and the IPA(Importance-Performance Analysis) was conducted to compare importance and satisfaction from kitchen laboratory facilities which have been a key element of culinary education. Results of this study can be summarized as follows. Firstly, it was found that performance (M=3.42) for culinary practice facilities was lower than importance(M=4.09) for culinary practice facilities. Secondly, through IPA, the importance and satisfaction of culinary laboratory elements showed some differences between the students who had have some educational experience in culinary art prior to enrollmnet and those who had not. The former students attached importance to the usefulness of facilities rather than the size of facilities. And as rapidly improved factors, they answered ventilation and water supply facilities for culinary laboratories. The application of this study in physical environment of culinary education will contribute to improve students` satisfaction with the quality of education. However, the critical point of this study is a limited sampling, so the results of this study cannot be generalized.
This study assessed ecological health using a multi-metric fish model from 15 sites in the headwater watershed of southern Han River during June${\sim}$August 1999 and then compared the health with conventional community diversity index to figure out differences between health and diversity index. For the analysis, we adopted 10 metric IBI model for regional applications. During this survey, total number of species sampled were 24 (6 families) and varied depending on magnitude of ecological disturbance and stream order. In the mountainous streams, mean proportion of sensitive and insectivore species was composed of 91% and 56%, respectively, indicating a potential healthy conditions. However, tolerant species with 66% and omnivore species with 76% were sampled from the 2nd order stream, which was shown deterioration in the physical habitat quality. In the overall watershed, mean IBI value was 38, judging as "fair" condition by the health criteria. Values of Individual IBI were closely associated with stream order and this pattern was similar to other mountainous streams showing low chemical pollutions and disturbance. Our comparison between IBI and diversity index over the stream order showed a distinct difference; Shannon-Weaver diversity index overestimated the actual community conditions and the variation range in the 2nd order stream was greater in the diversity index. Overall data suggest that the multi-metric approach may to a useful tool for stream ecosystem management and the conventional diversity index may not effective unless the stream order is considered for the stream evaluation.

Although the Dreamland site was the only flat amusement park in the northern part of Seoul, the site lost its function as a regional park due to aging and, therefore, was no longer in use. The site is surrounded by currently existing high dense low-story housing blocks and proposed new towns. A renovation plan for Dreamland was raised by the City of Seoul to enhance the quality of the urban environment in the northern part of Seoul. This study articulates the design concepts and strategies of the prizewinning work of the International Design Competition for Gangbuk Large Park. The three key points can be summarized as follows: First, this design proposal tried to find a new possibility for a large mountain park in an urban areas. These days, mountain parks are used limitedly as ordinary living spaces for activities such as a walking, hiking, and physical training. New strategies were sought to reconstruct the sentiment with which our ancestors enjoyed the mountains. Second, this proposal tried to make Dreamland a socially self-sufficient park. We designed a park which generates self-energy and which communicates with the city, not a park which only exists as a green island in a city. Lastly, rain fed paddy fields, a typical Korean vernacular landscape, was a tangible space which represented people's life-styles harmonizing with the nature. Rain fed paddy fields is a design motif which puts the three surrounding mountains together with the site. It is expected that the new design will works as a noted place.
The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.
Pesticide is used to protect the crops, but also become a cause of polluting the environment. Perform a risk assessment using physical and chemical properties, environmental fate and toxicity data in order to determine the pesticide registration. The aquatic model estimates pesticide concentrations in water bodies that result from pesticide applications to rice paddies and apple orchard. The used models are the PRZM, EXAMS and AGRO shell (PA5), Rice Water Quality Model (RICEWQ) and Screening Concentration In GROund Water (SCI-GROW). The residual concentration of water body was estimated using meteorological data, crop calendar and soil series of Korea. The chosen pesticides were butachlor, carbofuran, iprobenfos and tebuconazole. It has shown the potential that the RICEWQ is possible to predict residue level in water of butachlor and iprobenfos, because the maximum value in water monitoring data is lower than the peak concentration of the model, and the minimum value is lower than the average annual concentration of the model. But RICEWQ was insufficient to predict exposure concentrations in ground water. The estimated exposure concentrations of carbofuran in ground water is very higher than in surface water because of its low soil adsorption coefficient. Although tebuconazole were not detected in the water monitoring that means very low concentration, it is possible that the PA5 can be used to predict residue level in water.
