The aim of this research is to investigate the various activities of residents conducted at the regenerated Park as well as conflicts and participations of residents that appeared in the regenerative process of the Park in urban low-income group settlement where public spaces for the community are absolutely insufficient, focusing on the Jeonpo-Dolsan Park. Moreover, this research examines the influences of the newly regenerated Park on the daily lives of residents and the meanings and roles of the Park to the residents. The Park not only provided the functions of a general parks but also served the role as the space for the culture, participation, discussion and assembly. Also dirty and uncleaned landscapes was improved because of the regeneration of Park. It was confirmed that the Park contributed to elevating the life quality of residents in urban low-income group settlement by forming an open-minded village, constructing public space for the community and communicating with discontinued neighboring villages. The Park' regeneration was produced not by executing the unilateral redevelopment policy of the administration for the urban low-income group settlement but by inducing the participation of the village residents. Owing to this, the creative regeneration of the Park aroused a motive for place attachment and sense of belonging, expanded public morals and prepared the opportunity to change as a hopeful space in awareness.
The study examined the Korean medicine industry from the perspective of the innovation system theory of each business, while it concentrated on the conflict between traditional Korean medicine and Western medicine, which have a major influence on the innovation system of Korean medicine industry, rather than the innovation system itself. The Korean healthcare system is a dual system of Western and Korean medicine, yet the definitions of Western medical practices and Korean medical practices are ambiguous. Thus the distinction of dual system depends on judicial precedents, and the innovation of Korean medicine has been inhibited due to the excessive emphasis placed on the Western medical practice in both healthcare system and pharmaceutical system. First of all, the usage of most medical devices derived from the development of modern medical engineering is not permitted in the Korean medicine industry, on the basis that most of the medical devices were originated from the Western medicine field. Secondly, new drugs using natural substances, once approved by the drug administration, cannot be prescribed by the Korean medicine industry although they are developed based on Korean medicine. Thirdly, the major safety issues on herbal medicine are about hazardous materials in medicinal herbs and liver toxicity of prescribed herbal medicine. The problem of hazardous materials can be solved by appropriate quality and safety tests in the cultivation and importation process. Whereas the Korean medicine circles points out that the liver toxicity issue is only a unilateral condemnation by the Western medicine circles.
A survey of risk perception in Korea was conducted in 2001 with a special emphasis on industrial and technological risks. This article summarizes the characteristics of risk perception in consideration of socio-demographic background of respondents. The survey with sample size of 1,870 evaluates the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, and nuclear power generation. Risks are categorized by using factor analysis to clarify attitudinal or behavioral properties of risk perception. Research findings show that the level of perceived risk does not correspond to the statistical level. Socio-demographic variables are significant predictors in explaining risk perception, or the discrepancies between "subjective" and "objective" risks. Effective risk communication can reduce the perceptional discrepancies, improve the awareness of technological risks, and ultimately facilitate the process of making and implementing policies for risk management and safety regulation. This article tries to provides policy guidelines for "Who is the target for risk communication" and "Which risk has the policy priority for safety improvement." Married females at the age of 30s and 40s with lower education and lower income in small cities are more vulnerable to risk misperception than other groups. More information and knowledge regarding unfamiliar, intangible, new technological risks should be delivered to the vulnerable groups for reducing perceptional bias. Society-wide safety can be improved by integrating policy, human, and social factors as well as techno-engineering advances.
Nowadays, studies on the fusion of Semantic Web technologies are being carried out to promote the interoperability and value of sensor data in an IoT environment. To accomplish this, the semantic translation of sensor data is essential for convergence with service domain knowledge. The existing semantic translation technique, however, involves translating from static metadata into semantic data(RDF), and cannot properly process real-time and large-scale features in an IoT environment. Therefore, in this paper, we propose a technique for translating large-scale streaming sensor data generated in an IoT environment into semantic data, using real-time and parallel processing. In this technique, we define rules for semantic translation and store them in the semantic repository. The sensor data is translated in real-time with parallel processing using these pre-defined rules and an ontology-based semantic model. To improve the performance, we use the Apache Storm, a real-time big data analysis framework for parallel processing. The proposed technique was subjected to performance testing with the AWS observation data of the Meteorological Administration, which are large-scale streaming sensor data for demonstration purposes.
There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.
Purpose: The hydroxymethylglutaryl coenzyme A reductase inhibitors (statins) are widely used in the treatment of dyslipidemia for the lowering of cholesterol. And studies about simvastatins have been shown to enhance bone formation in vitro and in vivo in rodents. But some other researchers have reported that there was no anabolic effect abouts simvastatins on bone. The peripheral distribution beyond the liver represents a small fraction of an orally administered dose. We hypothesize that this poor peripheral distribution is the likely reason that simvastatins, yield ambiguous results as anabolic agents. We therefore investigated whether the effects of simvastatins on bone may be enhanced by subcutaneous administration, providing better peripheral delivery of these drugs. Methods: 36 rat unilaterally mandible fractured models were prepared and divided into two groups. The simvastatin treated group where 1 mg/kg of simvastatin was daily injected subcutaneously. The same dose of normal saline was injected on the control group. And 3 rats in each group were sacrificed and taken bone samples in each week. Bone sample was evaluated with tensile strength and histological morphology after 1, 2, 3, 4, 5 and 6 weeks. Results: In simvastatin treated group, the fracture healing process, chondrocyte aggregation, collagen formation and trabecular bone formation was rapidly proceeded than the control group in histologically. The tensile strength of the simvastatin treated group was 1.02, 2.25, 3.95, 4.42, 5.49 and $6.00N/mm^2$ by weeks. The control group data was 0.60, 1.05, 2.17, 3.75, 4.15 and $5.17N/mm^2$ by weeks. The average tensile strength was higher by $1.04N/mm^2$ in simvastatin treated group. Conclusion: The currently available data on the effects of simvastatin on bone has done to confirm the finding that simvastatin helps fracture healing. And the potential for simvastatin to be used as anabolic agents for bone when delivered by the subcutaneous route.
Objectives : To investigate the current status of hospital-based health promotion programs in Korea and to elucidate the factors which affect to the process of implementation. Methods : We conducted a mail survey of all 875 hospitals in Korea from March to May 2001. In reference to 12 specific kinds of health promotion programs, hospital CEOs were asked whether their hospital have such programs, whether they are fully staffed and whether the program is paid for by the patients. Contextual factors(location, hospital type, number of beds, length of operation, public/private status, economic level of the community, the level of competition) and organizational factors (the extent of market, compatibility with vision, formalization), strategic types of the CEOs (defender/analyser/prospector) were also surveyed. The relationships between each variable and the implementation of health promotion services, activation of services, and the target groups(patient/community resident) were analyzed by univariate analysis and the independent effects of these variables were examined with multiple logistic regression. Results : 100 of 125 hospitals responding (84.8%) had mere than one health promotion program. However, they showed fluctuations in the adoption rate of each programs, meaning that comprehensive health promotion services were not provided. Many programs were not fully staffed and few hospitals had paid programs. In factors affecting health promotion service implementation, private hospitals showed a higher rate in implementation than public hospitals. In contrast, when the competition among nearby hospitals was intense, the level of implementation of service lowered. In the strategic type of the CEOs, the prospectors were shown to have instituted more health promotion programs in their hospitals and the analysers had a greater tendency to have programs for community residents than the defenders. Conclusion . Considering the above results, contextual factors may contribute greatly to the introduction of health promotion services in Korean hospital, although the CEO's personal preference and organizational factors play a larger role in the activation of services. Additionally, the CEO's personal preference may be the major influencing factor in the introduction of programs for community residents.
Sodium nitrite which is added in processing of meat process product to develope color and to keep bacteria from growing, produces toxic substance after reacting, bring about deterioration by oxidation and toxic substance. So natural material is needed to substitute this sodium nitrite for. Chitosan which is made of chitin by processing of deacetylase, has various function of antibiosis and antimutation. We studied about the substitution effect of chitosan against sodium nitrite in pork sausage. As a result, of storing the sausage, antimicrobial effect of sodium nitrite was detected by 0.35% of chitosan(M.W. 30 kDa). This chitosan had same color developing effect even though addition content of sodium nitrite reduced until 15 ppm which is less than 1/10 of standard level. And chitosan decreased fast a residual nitrite. This result shows that chitosan inhibited a formation of nitrosamine.
Using agar and gelatin as wall materials, onion oil was microencapsulated using the extrusion spraying technology. A sensitive methodology was developed for quantitative determination of the microencapsulation yield through ethyl acetate extraction and gas chromatographic analyses. Optimal conditions for the microencapsulation process consisting of the ratio of [core material, Cm] to [wall material, Wm] ($X_1$), temperature of dispersion fluid ($X_2$), detergent concentration in dispersion fluid ($X_3$), and concentration of emulsifier $(X_4)$ were determined using response surface methodology. The regression model equation for the yield of microencapsulation (Y, %) of onion oil could be predicted as $Y\;=\;97.028571-0.775000\;(X_1)-0.746726\;(X_1){\cdot}(X_1)\;-\;1.100000\;(X_3){\cdot}(X_2)$. The optimal conditions for the microencapsulation of the onion oil were determined as the ratio of [core material] to [wall material] of 4.5 : 5.5 (w/w), the temperature of dispersion fluid of $17.1^{\circ}C$ detergent concentration in dispersion fluid of 0.03%, and the concentration of emulsifier of 0.42%. Results revealed the most stable microcapsule of onion oil could be formed with the highest yield of microencapsulation (more than 95%) under optimal conditions.
In case of doenjang, solution of browning problem might be an important remedy in order to dissolve consumers' dissatisfaction, therefore this study was performed to develop traditional doenjang which has improved in color aspect for consumers' needs. Physicochemical compositions and color values of commercialized traditional doenjang which was processed by history references of our country, were analyzed. doenjang used as samples were processed with traditional meju, which were made with soybean and mixed with various rates after following process such as soaking, steaming, cooling, chopping and grinding. The doenjang processed were storaged at $30^{\circ}C$ for 27 days, and their amino-N, pH, color values and sensory evaluation were analyzed with fermentation period. Furthermore, nitrogen results analyzed were compared with that of commercialized traditional doenjang. In the comparison with control, treated with only traditional meju, and doenjang treatments processed with different mixing rates of traditional meju and steamed soybean, the content of amino-N in control were higher than the others, and the contents of amino-N decreased with increasing contents of steamed soybean. Their pH were changed weak alkalic region into weak acidic region with fermentation period. In the aspect of color, traditional doenjang having the rate of traditional meju and steamed soybean (1:4) was most improved and also, in comparison of result of sensory evaluation with commercial traditional doenjang, its color, taste and falvor were evaluated predominent, therefore it might be thought to have competition on the market.
