This study aimed to develop a service model that uses a deep learning algorithm for detecting diseases and pests in strawberries through image data. In addition, the pest detection performance of deep learning models was further improved by proposing segmented image data sets specialized in disease and pest symptoms. The CNN-based YOLO deep learning model was selected to enhance the existing R-CNN-based model's slow learning speed and inference speed. A general image data set and a proposed segmented image dataset was prepared to train the pest and disease detection model. When the deep learning model was trained with the general training data set, the pest detection rate was 81.35%, and the pest detection reliability was 73.35%. On the other hand, when the deep learning model was trained with the segmented image dataset, the pest detection rate increased to 91.93%, and detection reliability was increased to 83.41%. This study concludes with the possibility of improving the performance of the deep learning model by using a segmented image dataset instead of a general image dataset.

Environment friendly agricultural material products (EFAMs) in current market were evaluated for their insecticidal or acaricidal activities. EFAMs were evaluated against Tetranychus urticae, Plutella xylostella, Myzus persicae and Nilaparvata lugens in spray method. Several EFAMs indicated high control value in spray method. Hatchability of T. urticae was relatively high after EFAM treatment. some materials show high insecticidal activities against P. xylostella larvae but not against eggs. Few mete rials showed more than 80% insecticidal activities against M. persicae and N. lugen. The control value of more than half the materials for pest control was lower than 60%. EFAMs containing S. flavescens, neem oil and Rape showed higher control value.

The main goal of this study is to examine the competition intensity in the Korean bakery franchise industry and to identify the core competencies of the industry's leading company, Paris Baguette. The frameworks of PEST analysis, Cross Impact analysis, a Five Forces Model, a Value Chain, and VRIO analysis. PEST and Cross Impact analysis were employed to investigate the industry's external environment, and the results indicated that 'increased attention on corporate's Creating Shared Value (CSV) activities' is the most influential factor among others. The analysis using the Five Forces Model found industry rivalry and substitutes were the greatest threats. Finally, the results of Value Chain and VRIO analysis identified four core competencies of Paris Baguette: its CEO's craftsmanship, e-procurement system, quality of dormant dough, and hub system. Multiple managerial implications are suggested for practitioners in the marketing area, especially in the saturated market environment.

Currently, two-dimensional culture is the main keyword in Chinese contents market. In China, many capital and economic giants have entered into two-dimensional cultural market because the number of users and the interest of the public for two-dimensional culture are increasing day by day. The reason for the rise of the two-dimensional culture into the mainstream culture is not only the switching of the mainstream consumer class but also Two-Dimensional Culture forms a huge industrial chain covering many areas including movies, performances and theme parks in addition to ACGN (Animation, Comic, Game and light Novel), the second is that more people are participating in Two-Dimensional Culture due to the specific audience with high social environment and loyalty and the third is looking for the role of the users in Two-Dimensional cultural content from three characteristics, such as strong cultural prevalence. This study analyzed the Chinese two-dimensional cultural environment through PEST(Political, Economic, Social and Technological analysis) In addition, as the ecological environment and communication method of Two-Dimensional Culture users changed, the users became active participants and the second producers of contents. I examined the way of using the users' contents through the phenomenon of 'Barrage'. Therefore, this study discussed the appropriate development path for the user-oriented contents industry in the Chinese Two-Dimensional cultural environment.

Genetic engineering, which was started by the E. coli gene manipulation, has led to rapid development in all area of life sciences. Recently, genetic engineering, which is an insertion or a removal technique of a specific gene on chromosomes, has been established and is usefully available in the applied life sciences including medicine and agriculture. In this review, we briefly explain pest management focusing on Release of Insects carrying a Dominant Lethal (RIDL) that is a highly economic and environment-friendly method of biological pest control. Although at present RIDL confronts many difficulties in applying directly in fields, it will be one of the best methods for the pest management in the near future without pesticides and disturbing ecosystem by the continued development of genetic engineering. However, these powerful techniques must be considered with great care to avoid harm to ecosystem.

Countries around the world are making active efforts to reduce greenhouse gas emissions. Korea is also pursuing a policy of abolishing aging coal power and converting it to LNG power generation. However, in Korea, gas turbine manufacturing technology has not been localized, so all of it is imported and installed from overseas manufacturers. Therefore, this paper examines the domestic and foreign environment of the gas turbine power generation industry and proposes a strategy to develop and expand the supply of Korean gas turbine technology by applying the PEST-SWOT-AHP methodology. As a result of the research, the strategy to develop and expand the supply of Korean gas turbine technology can be summarized as 1) strengthening the role of power generation public enterprises to develop and promote commercialization of gas turbine technology, 2) expanding the proportion of LNG power generation to reduce greenhouse gases, 3) the government's active efforts to create an ecosystem for the gas turbine industry, and 4) forming a public consensus on the construction of LNG power plants.

As a series of studies to develop pest management system for sweet persimmon production matched with the quarantine criterion of sweet persimmon-imported county, a survey was conducted by questionnaire on pest management practice and scheme of increasing income in sweet persimmon farms in Korea. Above 80% of sweet persimmon farmers was over fifties in age. The greatest limiting factor for sweet persimmon production was thought to be disease by the farmers. Percentage of farmers who answered that the most important pest is anthracnose cause by Gloeosporium kaki, and stink bugs was 64.6% and 73.5%, respectively. In particular, the farmers did not consider Dichocrocis punctiferalis, a main targer insect for quarantine in USA, as serious problem. Obtaining information on pest management practice or decision-making on both selection of pesticide and time of pesticide application depended highly on their own experience with the highest proportion. Eight to nine times of pesticide applications a year was highest among farms with 56.6%. More than 80% of farmers recorded the diary of pesticide application. farmers considered increasing cost for pest management as the greatest problem with 35.4% in proportion, and 34.5% of farmers pointed out that increase in export is essential for increasing farm income with highest proportion.
