As the first step of a research on the establishment of control strategy for grapevine diseases and insects, the current status of pest control and yield losses by them were surveyed from grapevine growers of Korea. For insects, the most difficult to control was a grapevine stem borer and a grapevine clearwing moth was the next. On the other hand, several diseases including anthracnose, downy mildew, powdery mildew, bird's eye rot, leaf blight, were answered by the growers. The occurrence of the pests varied to the cultural practices. Yield loss was more serious in rainfall intercept culture than in plastic film house culture and diseases caused more loss in yield than insects did. However, the grapevine grower's potential for the identification of the kinds of pests was not high enough. When the pest was observed, the growers consulted mainly with local pesticide dealers or neighbouring growers and usually applied the pesticides prescribed by the dealer. More than half of the growers did not use pest control calendar, and most of the growers applied pesticides before any symptom appeared. Also, more than half of the growers applied mixture of at least more than 1 kind of pesticide and nutrients. Insecticides were applied less than 5 times during the season, but it was more than 6 times for fungicides. In the pesticide selection, the growers checked control effect first, regardless of the registration, and the pest control cost per unit area varied very much depending on the growers.
In regards to museum planning of Korea, it is mainly depending on overseas cases and relevant domestic books without systematic guideline on the space programme in a museum. Therefore, it is urgently required to establish systematic index as it is incapable of proposing detailed analysis and index in accordance with each element. As various problems occurred due to above reason, total floor area of museum was divided by the area of exhibition section, storage section, research section, and public & other area and its ratio was calculated for statistics targeting 614 museums built after 1990's when many public museums were built with the settlement of local self-governing system and the type of museums was diversified. It was again classified into 4 elements of period, region, scale, and type and then the influence of each element on each section of museum was understood through integrated analysis. First, looking into the space programme in regards to total floor area, the floor area ratio of exhibition section, storage section, and research section decreased and the floor area ratio of public & other area increased with the increase in total floor area. It was because not only rest area but also a space to enjoy various cultures, gaining new experience, and accumulate knowledge is located in public & other area. Second, it was revealed that the ratio of exhibition section and storage section has been decreasing since 1990's and ratio of research section and public & other area has been increasing as they can play various roles such as the education and convenience to satisfy cultural desires of visitor in accordance with current trend. Third, it was proved that floor area ratio of exhibition section is lower than storage section in museums located in highly urbanized region. In addition to this, it was revealed that the floor area ratio of research section is in proportion to the population density. As a result of study, significant relation was displayed in scale, era, and region among 4 elements thus it could be utilized as reference for the space programme of domestic museum planning in the future.
Hallyu in East Europe has been spread since the end of the 2000s and contributed to boost the familiarity and favorability of Korea. Hallyu in East Europe started from Romania and Hungary, Korean dramas and K-Pops spread to Bulgaria. Korea and Bulgaria established a diplomatic relations in 1990; however, people of both countries do not share enough information or knowledge on each other. This study aims to understand the meaning of Hallyu and the ways of building cultural relations through Hallyu based on the cognitions and attitudes toward Korea and Korean culture in Bulgaria. It conducted the Focus Group Discussions(FGD) for 24 Sofia residents in their 20s and 30s. The FGD questions were mainly on the level of familiarity and of impacts of Hallyu in Bulgaria. The Hallyu in Bulgaria is still not so popular although Hallyu has been promoted through the diverse activities of Korean Embassy, Sofia University, Korean language institutions, and the Hallyu fans. The economic and cultural impact of the Hallyu is not yet viable in Bulgaria. In order to be recognized as one of the foreign popular culture in Bulgaria, Hallyu should be promoted with various endeavors for Bulgarian people to experience Korean culture beyond Korean drama and K-Pops based on the understanding of socio-cultural characteristics of Bulgaria. Then, Hallyu will be spread by producing Korean dramas, films, and K-pops reflected by local cultural characteristics in Bulgaria and hybridity of Korean popular culture.

Forest fires are one of the most important environmental risks that have adverse effects on many aspects of life, such as the economy, environment, and health. The early detection, quick prediction, and rapid response of forest fires can play an essential role in saving property and life from forest fire risks. For the rapid discovery of forest fires, there is a method using meteorological data obtained from local sensors installed in each area by the Meteorological Agency. Meteorological conditions (e.g., temperature, wind) influence forest fires. This study evaluated a Data Mining (DM) approach to predict the burned area of forest fires. Five DM models, e.g., Stochastic Gradient Descent (SGD), Support Vector Machines (SVM), Decision Tree (DT), Random Forests (RF), and Deep Neural Network (DNN), and four feature selection setups (using spatial, temporal, and weather attributes), were tested on recent real-world data collected from Gyeonggi-do area over the last five years. As a result of the experiment, a DNN model using only meteorological data showed the best performance. The proposed model was more effective in predicting the burned area of small forest fires, which are more frequent. This knowledge derived from the proposed prediction model is particularly useful for improving firefighting resource management.
The palatine tonsils(tonsils) and pharyngeal tonsils(adenoids) are situated at the entrance of the respiratory and alimentary tracts and represent the first site of contact with a variety of microorganisms and other antigens present in food and inhaled air. They are known as lymphoid organs carrying out the function of cellular and humoral immunity, and so they form a local protective barrier. And the expression of the vascular endothelial adhesion molecules is known to play an important role for the inflammatory reaction in tonsils and adenoids as well as in other inflammatory tissues, by binding with the receptors on the surface of leukocytes. But although several scientific hypotheses on the role of these lympoid tissues have been suggested, their complete functions have remained unknown. The purpose of this study is to present an basic data of the knowledge on the immunologic physiology of the tonsils and adenoids and their role as active immunologic organs that reinforce the mucosal immunity of the entire upper aerodigestive tract. We examined 16 human tonsils and adenoids and the expression of three endothelial adhesion molecules, vascular endothelial adhesion molecule-1(VCAM-1), intracellular adhesion molecule-1(ICAM-1), and E-selection, in tissue sections using immunohistochemistry. We used the inferior turbinate mucosa obtained from 9 patients getting septal surgery as a control group. The expressions of vascular endothelial adhesion molecule-1(VCAM-1) and intracellular adhesion molecule-1 (ICAM-1) were significantly higher in the tonsils and adenoids. But respectively, there were no significant differences between the tonsils and adenoids. The expression of E-selection was significant higher in the tonsils, but not in the adenoids. We observed that tonsils and adenoids showed significantly higher expressions of vascular endothelial adhesion molecule-1(VCAM-1), intracellular adhesion molecule-1(ICAM-1), and E-selection (in the case of E-selection, only in the tonsils). We propose that these adhesion molecules play an important role for the immunologic reaction by the transendothelial migration of lymphocytes and binding with the receptors on the surface of leukocytes.
In this world, the interest in the marine leisure-sports, nature friendly oriented, has been increased. The width of leisure activities has became enlarged because of expansion of leisure time and the changes of recognition on the rational management and use of marine resources. Marina ports influence significantly marine leports and this paper reviewed the maria ports status and problems. This Country has strived to develop marina ports in local areas, designing the 1st basic National Plan of Marina Development. We have keen interest in Marina but have no detail strategy and preparation. This paper suggested how marina port shall be developed for the expansion of marine leports and what strategies shall be adopted for the activation of the facilities. After reviewing the previous researches and with the results of questionnaire survey, this paper suggested two types strategies. First on the policy oriented point, it suggested 10 alternatives on the perspectives of development and operation areas. Secondly, it proposed some strategies for the activation of marina ports on the aspects of 4Ps of marketing. This paper theoretically groped the activation schemes with the knowledge and experiences of experts, but it is recommended furthermore some survey on the practical field and user attitude must be progressed.
This article explores the potential learning materials and methods of science practice from exhibits, and how those are presented in natural history museums as a feasible science inquiry community. The idea of science inquiry community was offered as a form of science practice that ended with science learning. A grasp of 'scientific practice to learning' is understood as a way to conceive scientific methods as well as facts and understanding knowledge. To get educational implications on the scientific practice of 'earthquake' as a socioscientific topic in the communities, we analyzed 1) the relationship between earth science curriculum and exhibits related to 'earthquake', 2) the educational goals and intentions of educators, and 3) the characteristics of the exhibits in the American Museum of Natural History and in the Smithsonian National Museum of Natural History. The results of this study showed that those museums presented the exhibits consisting of various and practical cases and events of 'earthquakes' as a socioscientific topic related to their curriculum. At the target museum, it was clearly stated that the pursuing educational goals focused on relations with local interests and socioscientific issues. For making earthquakes relevant to visitors, delivering lived experiences with raw data and interactive media was emphasized in exhibit characteristics.

The miracle of Korean economic development is the benchmarking for the developing countries. Among them, the STP of Science and technology area is very important case they tring to learn from Deadeok, Korea. Ecuador and Kazakhstan have the huge natural resources and they have interested in the model of Daedeok STP. This paper study about their needs and Daedeok's capability, and effective implementing factors. This paper suggest a six one based on the Daedeok Innopolis experiences for the successful local STP. First, most important thing is human resource development strategy for the knowledge and technology transfer. Second, the construction of Engineering Center for the collaboration of industry and academy is needed. This is important to have a bargaining power to the appropriate technology transfer. Third, they need a hardware and software infrastructure to the technology commercialization. It include a incubator, manager, and complimentary asset. Fourth, they have to connect with market closely for the venture creation and growth. Fifth, the clustering is realized by the STP construction. Lastly, leadership is critical factor to the absorptive capacity.
Anaerobic digestion is an efficient and renewable energy technology that can produce biogas from a variety of biomasses such as animal manure, food waste and plant residues. In developing countries this technology is widely used for the production of biogas using local biomasses, but there is little information about the value of these biomasses for energy production. This study was therefore carried out with the objective of estimating the biogas production potential of typical Vietnamese biomasses such as animal manure, slaughterhouse waste and plant residues, and developing a model that relates methane ($CH_4$) production to the chemical characteristics of the biomass. The biochemical methane potential (BMP) and biomass characteristics were measured. Results showed that piglet manure produced the highest $CH_4$ yield of 443 normal litter (NL) $CH_4kg^{-1}$ volatile solids (VS) compared to 222 from cows, 177 from sows, 172 from rabbits, 169 from goats and 153 from buffaloes. Methane production from duckweed (Spirodela polyrrhiza) was higher than from lawn grass and water spinach at 340, 220, and 110.6 NL $CH_4kg^{-1}$ VS, respectively. The BMP experiment also demonstrated that the $CH_4$ production was inhibited with chicken manure, slaughterhouse waste, cassava residue and shoe-making waste. Statistical analysis showed that lipid and lignin are the most significant predictors of BMP. The model was developed from knowledge that the BMP was related to biomass content of lipid, lignin and protein from manure and plant residues as a percentage of VS with coefficient of determination (R-square) at 0.95.This model was applied to calculate the $CH_4$ yield for a household with 17 fattening pigs in the highlands and lowlands of northern Vietnam.
Background and Purpose: Indigenous people who leave their hometowns and move to the city to earn a living became urban aboriginals. During the process of adapting to urban living situations, they may use various coping strategies such as smoking to overcome their stress. Therefore, it is crucial to provide health education including smoking prevention, increasing knowledge regarding of tobacco hazard, self-efficacy of anti-smoking, and adjusting smoking behavior so as to empower their anti-smoking motivation to prevent lung cancer. The purpose of this study was to explore the effectiveness of an anti-smoking program on urban aboriginals in Taiwan. Methods: A quasi-experimental study design with purposeful sampling was employed. A total of 125 aboriginal subjects were recruited from two local churches at Shu Lin area in northern Taiwan. Subjects were divided into an experimental group (n =64 ) and a control group (n = 61). Both took pre-tests in order to set baseline values, and only the experimental group participated for 3-weeks in the anti-smoking program classes. Both groups took post-tests immediately after the intervention in order to evaluate the immediate effects of the teaching program, and a follow-up test was conducted four weeks after the intervention. Data were analyzed using descriptive statistics, one-way ANCOVA, and repeat measure ANCOVA. Results: After controlling for confounding variables, the results showed that there were statistically significant differences in the self-efficacy of anti-smoking and smoking behavior between experimental and control groups in the immediately post-test and the follow-up test (p < 0.05). However, there was no significant differences in the recognition of hazards of smoking at eiter time point. Conclusions and Implications for Practice: The findings of this study revealed that the anti-smoking program effectively improved self-efficacy of anti-smoking, and decreased the smoking behavior in urban aboriginals. They provide useful information as a reference regarding of aboriginal health promotion to health providers. It is imperative that anti-smoking be reinforced for those regular smokers to prevent induction of lung cancer.
