Recently, the number of diabetic patients have been increased with westernized living way and meal habitation. The regulation of blood sugar concentration is very important for diabetic patients to keep homeostasis and, to prevent acute or chronic complications. Epinephrine combined with lidocaine is used in dental clinic extensively. And epinephrine combined with lidocaine also effects on decreasing the blood leakage volume by constricting micro vessle and arteriole. But, So far there are few researches about the effect of epinephrine contained in dental local anesthetic agent on the blood sugar of diabetes during minor oral surgery. The purpose of this study was intended to investigate whether epinephrine which combined with dental local anesthetics influence body glucose level in diabetes patients by glucose monitoring. The subject of this study were 38 diabetic patients and 38 normal adults, each patient was checked body glucose after a meal 2 hours later with resting state, and injection 1:100000 epinephrine with dental lidocaine 54 ml or lidocaine 54 ml only. And then the body glucose level was checked 5 minutes and 30 minutes after injection. The results were analyzed by two way ANOVA test (p<0.05). The results were as follows: In the experimental group 1, the mean of the blood sugar level was 180.3 mg/dl before an anesthetic injection, 182.8 mg/dl after 5minutes of the anesthetic injection and 182.2 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the experimental group 2, the mean of the blood sugar level was 237 mg/dl before an anesthetic injection, 234.5 mg/dl after 5minutes of the anesthetic injection and 231.8 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 1, the mean of the blood sugar level was 117.6 mg/dl before an anesthetic injection, 119.1 mg/dl after 5minutes of the anesthetic injection and 129.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 2, the mean of the blood sugar level was 104.2 mg/dl before an anesthetic injection, 102 mg/dl after 5minutes of the anesthetic injection and 105.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05).

Although traditionally perceived as being a visualization and asset management resource, the relatively rapid rate of improvement of computing power, coupled with the proliferation of cloud and edge computing and the IoT has seen the expanded functionality of modern Digital Twins (DTs). These technologies, when applied to buildings, are now providing users with the ability to analyse and predict their energy consumption, implement building controls and identify faults quickly and efficiently, while preserving acceptable comfort and well-being levels. Furthermore, when these building DTs are linked together to form a community DT, entirely new and novel energy management techniques, such as demand side management, demand response, flexibility and local energy markets can be unlocked and analysed in detail, creating circularity in the economy and making ordinary building occupants active participants in the energy market. Through the EU Horizon 2020 funded TwinERGY project, three different levels of DT (consumer - building - community) are being created to support the creation of local energy markets while optimising building performance for real-time occupant preferences and requirements for their building and community. The aim of this research work is to demonstrate the development of this new, interrelated, multi-level DT that can be used as a decision-making tool, helping to determine optimal scenarios simultaneously at consumer, building and community level, while enhancing and successfully supporting the community's management plan implementation.

This paper presents a new approach to obstacle avoidance for mobile robot in unknown or partially unknown environments. The method combines two navigation subsystems: low level and high level. The low level subsystem takes part in the control of linear, angular velocities using a multivariable PI controller, and the nonlinear position control. The high level subsystem uses ultrasonic and IR sensors to detect the unknown obstacle include static and dynamic obstacle. This approach provides both obstacle avoidance and target-following behaviors and uses only the local information for decision making for the next action. Also, we propose a new algorithm for the identification and solution of the local minima situation during the robot's traversal using the set of fuzzy rules. The system has been successfully demonstrated by simulations and experiments.

The study identifies gender stereotypes, examines the level of women's economic empowerment at the household level and explores the influence of factors on it. Data were collected from 159 randomly selected farm women using both qualitative and quantitative survey methods between January and March 2007 from three villages of the Mymensingh District of Bangladesh. Four key informants (2 local leaders and 2 development personnel) were questioned to elicit views in the light of boosting women's empowerment. Five constructs of empowerment covering 30 indicators were aggregated together to develop a cumulative economic empowerment index (CEEI) to obtain multidimensional views of women's empowerment. The findings show that there were some prejudices against women in allocating divisions of labour and access to education, food, property, decision-making and institutions. The distribution of the CEEI demonstrates that the majority of the respondents (86%) had a low to moderate level of empowerment. A multiple regression analysis showed positive significant effects of education, training, media contact and freedom of mobility on women's CEEI, while domestic abuse restrained it. It is concluded that interventions by development agencies in co-ordination with the local community was necessary to attain women's self-reliance in the study area. Development actors can undertake some core strategies to enhance women's level of awarencess, knowledge, skills, and productive resources through providing training, loans, and information. To change traditional beliefs, it is important to create awareness of various gender issues amongst rural people through different methods and media.

This study is designed to find out the difference of life satisfaction and depression between urban and rural elderly. The research method is a questionnaire that surveys those aged 60 and older. The collected data were analyzed by categorizing them into two groups, 503 residing in the elderly who live in Daejeon city and 676 in those who live in Chungnam area. The result of analysis indicated that; First, life satisfaction of the urban elderly was higher than that of the rural elderly(t=3.67, p<.001). But depression between the two groups, the elderly who live in urban area and those who live in rural area, did not show a statistically significant difference. Second, the factors influencing the life satisfaction of urban elderly were convenience of housing, economic level, health status, local safety, life attitude, and period of residence. Third, the depression of urban elderly significantly related to health status, life attitude, economic level, age, and convenience of housing. Fourth, the factors influencing the life satisfaction of rural elderly were health status, economic level, convenience of housing, local safety, life attitude, type of residence, and period of residence. Fifth, the depression of rural elderly significantly related to health status, life attitude, and economic level.

In this study, water resource topics, infrastructure, water supply, users, and economic indicators based on statistical annual standards for evaluating water welfare were selected by examining domestic and foreign water resource-related indicators. The level of water welfare was evaluated relative to 23 cities and counties in Daegu and Gyeongsangbuk-do using data from the Statistical yearbook, and places with high value of indicators urbanization and large populations were excellent in the infrastructure field, but overall analysis showed that small and medium-sized cities had higher levels. It is judged that it is necessary to develop continuous research and indicators that can evaluate and quantify the level of physical welfare that the people can feel by utilizing the results of this study. In future studies, it is necessary to systematically evaluate the level of water welfare by local governments in Korea through more diverse evaluation items and detailed indicators for each item so that it can be used as basic data for realizing water welfare.

At present, the main method of high-speed train chassis detection is using computer vision technology to extract keypoints from two related chassis images firstly, then matching these keypoints to find the pixel-level correspondence between these two images, finally, detection and other steps are performed. The quality and accuracy of image matching are very important for subsequent defect detection. Current traditional matching methods are difficult to meet the actual requirements for the generalization of complex scenes such as weather, illumination, and seasonal changes. Therefore, it is of great significance to study the high-speed train image matching method based on deep learning. This paper establishes a high-speed train chassis image matching dataset, including random perspective changes and optical distortion, to simulate the changes in the actual working environment of the high-speed rail system as much as possible. This work designs a convolutional neural network to intensively extract keypoints, so as to alleviate the problems of current methods. With multi-level features, on the one hand, the network restores low-level details, thereby improving the localization accuracy of keypoints, on the other hand, the network can generate robust keypoint descriptors. Detailed experiments show the huge improvement of the proposed network over traditional methods.

The purpose of this study was to develop an evaluation indicator for the industrialization of local cuisine. We conducted a literature study, interviews with experts, and a Delphi survey. The resulting evaluation indicator was divided into four groups and nine sub-groups. The four groups were locality, taste and functionality, industrial base, and business value. The nine sub-groups were traditionality, regionality, eating quality, nutrition and functionality, condition of development, technological level, rights and policy, marketability, and ripple effects. Also 22 items were created as indicators for evaluating classes ; historicity, sustainability, rarity, awareness of local resident, the number of similar restaurant, appearance, taste, nutritional balance, health functionality, availability of raw materials, suitability of environmental exchange of market, standardization of recipe, simplification of recipe, storability, intellectual property rights, government's policy, appropriacy of price, popularization, possibility of franchise, globalization, improvement of local image, vitalization of local economy. The four most important classes corresponded to one of the four groups. These classes were sustainability, taste, state (local autonomy) policy, vitalization of local economy. The implications of this study are that the possibility of industrializing the local cuisine of each region can be evaluated and applied. Moreover, these indicators could promote the discovery of local cuisines, support planning for the commercialization of local cuisine.

Since 1995, the Local autonomy era has opened, local festivals have been increasing throughout the country. Traditional culture festivals are also increasing. Performing traditional culture festivals is effective for maintenance and transmission of traditional culture as well as creation and nurturing of local culture. They are also effective promoting local economy. Depending on realization level of character, place and costume based on historic research, traditional culture festivals are classified as the "Representation event" or the "Reenactment event". But there are two problems. The first is unexacting classification method for festival types made by Central government yearly. The second is unable to meet one of two goals which are protecting traditional culture and stimulating local economy throughout increasing tourists. The purpose of this study is to suggest improvement of classification method for festival types, and to offer two suggestions for ensure successful local festivals. First of all, I suggest advanced classification method for festival types. For more sophisticated collection process of national festival status, local government department should ensure purpose of festivals, and central government department should add 3 steps to existing process. For example professional committee for judgement of festival types should be founded for consulting of local and central government department. The second suggestion is reinforcement of historic research for the Representation of traditional culture event. The representation of traditional culture should focus on protection of tradition, and could be perfect by continuous historic research. The last suggestion is cooperation with local governments each other for the Reenactment of traditional culture event. The Reenactment of traditional culture should focus on promoting local economy by increasing tourists. So local governments who have similar traditional events should cooperate to get preventing loss of resource and overcome weakness of promoting.

In this study, evaluation on the loaches from the various sources was carried out in respect of their taste compounds. The samples were classified by local, season and growing condition and evaluated in terms of composition, the refuse, contents of nucleotides and their related compounds, total and free amino acid, organic acid and fatty acid. Evaluation on the compositions revealed the fact that, in terms of the local, the imported loach contain a low level of fat and high level of ash, in comparison with Korean loach; in terms of growing condition, cultured loach contains a high level of fat and low level of moisture, in comparison with wild loach; and in terms of the season, the summer loach contains less moisture than the fall loath; but as for the contents of other component, the summer loach was superior. As for the refuse, the imported loach had a greater refuse than the Korean loach. In the growing condition, the wild loach had lower value than the cultured loach. There was no substantial difference in each season. Also nucleotide and these related compounds were detected in all of the samples, while ATP was not found. The content levels of such detected compound did not show a substantial difference in each condition. However, generally, the imported loach was poor in such compound and all of the samples were high in IMP. The samples were high in total amino acids. The local and growing conditions showed no substantial difference, while in the season, the summer loach had a higher content of total and essential amino acid than the fall loach. As for the contents of free amino acids, similar distribution of the composition was shown in each sample, even though there was little difference in their constituents. Also, total content of free amino acid varied with the conditions of the samples. As for total content of organic acid and the distribution of the composition, there was a little difference between each condition. In the season and growing condition, the summer loach was high in organic acid. As for the distribution of the fatty acid compositions, there was no substantial difference between each condition and each sample. In the case of the wild loach, the summer loach was high in ${\omega}-3$ polyunsaturated fatty acid and the fall loach was high in essential fatty acid. Similarly, in the case of the imported loach, the summer loach was high in ${\omega}-3$ polyunsaturated fatty acid and the fall loach was high in essential fatty acid.
