The advancement of Information and Communication Technology (ICT), along with the expansion of government and private investment in startup discovery and funding, has led to the emergence of startups seeking to generate outstanding results based on innovative ideas. As successful startups serve as role models, the number of aspiring entrepreneurs preparing to launch their own startups continues to increase. However, unlike entrepreneurs who challenge themselves with serial entrepreneurship after experiencing success, early-stage startups face various challenges such as team building, technology development, and fundraising. Accelerators play a dual role of mentor and investor by providing education, mentoring, consulting, network connection, and initial investment activities to help startups overcome various challenges they face and facilitate their growth. This study investigated whether there is a correlation between the characteristics of startups and their entrepreneurial performance, and analyzed whether accelerators mediate the relationship between startup characteristics and entrepreneurial performance. A total of 11 hypotheses were proposed, and a survey was conducted on 302 startup founders and employees located across the country, including the metropolitan area, for empirical research. SPSS 23.0 and Amos 23.0 were used for statistical analysis. Through this study, it was found that factors such as innovation, organizational culture, financial characteristics, and learning orientation among the characteristics of startups, rather than having a direct impact on entrepreneurial performance, are linked to entrepreneurial performance through the role of accelerators. By analyzing the impact factors of startup characteristics on entrepreneurial performance, this study presents research on the role of accelerators and provides institutional improvements. It is expected to contribute to the expansion of investment and differentiated acceleration programs, enabling startups to seize the market and grow stably in the market.

In this paper, we present a study aimed at analyzing how different rainfall measurement methods affect the performance of reservoir water level predictions. This work is particularly timely given the increasing emphasis on climate change and the sustainable management of water resources. To this end, we have employed rainfall data from ASOS, AWS, and Thiessen Network-based measures provided by the KMA Weather Data Service to train our neural network models for reservoir yield predictions. Our analysis, which encompasses 34 reservoirs in Jeollabuk-do Province, examines how each method contributes to enhancing prediction accuracy. The results reveal that models using rainfall data based on the Thiessen Network's area rainfall ratio yield the highest accuracy. This can be attributed to the method's accounting for precise distances between observation stations, offering a more accurate reflection of the actual rainfall across different regions. These findings underscore the importance of precise regional rainfall data in predicting reservoir yields. Additionally, the paper underscores the significance of meticulous rainfall measurement and data analysis, and discusses the prediction model's potential applications in agriculture, urban planning, and flood management.

This study was conducted to evaluate a knowledge on food components of muscle and adductor muscle of pearl oyster (Pinctada fucata martensii) as pearl processing byproducts. The concentrations of mercury and chromium as heavy metal were not detected in both pearl oyster muscle and adductor muscle, and those of cadmium and lead were 0.06 ppm and 0.11 ppm in only pearl oyster muscle, respectively. Thus, the heavy metal levels of pearl processing byproducts were below the reported safety limits. The volatile basic nitrogen (VBN) content and pH of pearl oyster muscle were 11.6 mg/100g and 6.31 and those of abductor muscle were 8.6 mg/100 g and 6.33, respectively. It was concluded that pearl oyster muscle and adductor muscle might not invoke health risk in using food resource. The contents of crude protein (16.5%) and total amino acid (15,691 mg/100 g) of adductor muscle were higher than those of muscle (11.2% and 10,131 mg/100 g) and oyster (12.1% and 11,213 mg/100 g) as a control. The contents of calcium and phosphorus were 95.4 mg/100 g and 116.0 mg/100 g in muscle, 75.2 mg/100g and 148.1 mg/100 g in adductor muscle, respectively. The calcium level based on phosphorus was a good ratio for absorbing calcium. The free amino acid contents and taste values were 635.5 mg/100 g and 40.2 in muscle, and 734.9 mg/100 g and 24.1 in adductor muscle, respectively, but that (882.8 mg/100 g and 40.2) of oyster was higher than those of pearl processing byproducts. Based on the results of physicochemical and nutritional properties, pearl oyster muscle and adductor muscle can be utilized as a food resource.

The use of information on natural resources is indispensable to most agricultural activities to avoid disasters, to improve input efficiency, and to increase lam income. Most information is prepared and managed at a spatial scale called the "Hydrologic Unit" (HU), which means watershed or small river basin, because virtually every environmental problem can be handled best within a single HU. South Korea consists of 840 such watersheds and, while other watershed-specific information is routinely managed by government organizations, there are none responsible for agricultural weather and climate. A joint research team of Kyung Hee University and the Agriculture, forestry and Fisheries Information Service has begun a 4-year project funded by the Ministry of Agriculture and forestry to establish a watershed-specific agricultural weather information service based on "high definition" digital climate maps (HD-DCMs) utilizing the state of the art geospatial climatological technology. For example, a daily minimum temperature model simulating the thermodynamic nature of cold air with the aid of raster GIS and microwave temperature profiling will quantify effects of cold air drainage on local temperature. By using these techniques and 30-year (1971-2000) synoptic observations, gridded climate data including temperature, solar irradiance, and precipitation will be prepared for each watershed at a 30m spacing. Together with the climatological normals, there will be 3-hourly near-real time meterological mapping using the Korea Meteorological Administration's digital forecasting products which are prepared at a 5 km by 5 km resolution. Resulting HD-DCM database and operational technology will be transferred to local governments, and they will be responsible for routine operations and applications in their region. This paper describes the project in detail and demonstrates some of the interim results.

In this study, we classified the group model construction types in the actual classroom situation implementing the instructional strategy mixed with individual model construction and group model construction types. The purpose of this study is to analyze the information flow and the individual construction types of each group model construction type to obtain implications for model co-construction in a real classroom environment. A two-session class on sound propagation was carried out for thirty-three 8th grade students in Seoul. A total of 65 individual model construction and 16 group model construction processes were collected and analyzed. The group model construction types were classified as unchanged, enumerated, and elaborated. The unchanged type was found in 8 groups, the enumerated type in 3 groups, and the elaborated type in 5 groups. The isolated individual and independent construction (i.I) were found mostly in the unchanged group construction type (50.0%) and enumerated group construction type (54.5%). In the unchanged type, the radial shape of flow in which one student's information is transmitted to all the members of the group appeared. In the enumerated type, the starting point of the information flow was observed from two individuals. In the elaborated type, linear information flow appeared and both the second dissemination and reflective construction (2d.R) contributed to the group model construction (58.3%). This study suggests a viewpoint that enables to understand the process of complex model construction in an actual classroom context rather than in an ideal situation. The result of this study suggests the necessity of a modeling strategy considering the characteristics of Korean small group culture. It is expected that the discussion will progress through further studies.

In this study, we investigated the characteristics of inquiry problems set by high school students who observed an 'unexpected phenomenon' and identified the effects of providing scientific information on setting inquiry problems. The subjects of this study were 126 eleventh grade students in Seoul that were randomly assigned to group A (N=66) and group B (N=60). In the study, watching a video of about 45 seconds of the unexpected phenomenon repeatedly for 20 minutes, all the students freely wrote inquiry problems that they wanted to carry out in their handouts. At this time, it is characterized that only the handout of group B additionally included scientific information on the unexpected phenomenon. As a result of the study, students, regardless of group, set more 'curiosity-oriented inquiry problems (i.e., focusing on inquiries they want to do rather than revealing what might be the cause of the phenomenon)' rather than going into a 'cause-oriented inquiry problem solving (i.e., revealing the cause of the phenomenon).' Among the curiosity-oriented inquiry problems, most of them were 'new-result inquiry problems (i.e., investigating what new results will occur by simply manipulating experimental situations).' It was also found that students who were provided with the scientific information tended to set significantly more inquiry problems using the provided information than those who were not (χ2(1)=8.996, p<.01), nevertheless the students with the scientific information did not set significantly more cause-oriented inquiry problems (χ2(1)=1.376, p>.05). The findings have been discussed from the four perspectives (i.e., lack of provided information, lack of opportunities to internalize the provided information, personal curiosity-seeking, and intuitive thinking), and implications for inquiry problem setting were suggested.

This research aimed to investigate the effect of business management of Korean restaurants on business performance and to propose an alternative. For this investigation, a survey was carried out targeting Korean restaurant managers in the capital area, and with 360 copies as sample, factor analysis, difference test, and multiple regression analysis were conducted. As a result of analysis, among the factors of business management of Korean restaurants, only information management and fund management appeared to have effects on both financial performance and nonfinancial performance. This means, in case of Korean restaurants, business performance can be improved by understanding every environment about food service management and customer demands, by investing fund in the right place, and by managing inefficient expenses. Therefore, it is most important for a Korean restaurant manager to cultivate knowledge in management and to put effort into cost-reduction of all employees.

This study was to identify the effects of hotel organizational service orientation on CRM(customer relationship management) performance. The organizational service orientation has been considered very important for excellent service quality in many existing studies. The data were collected from employees in deluxe hotels of the metropolitan area with the questionnaire. To test the hypotheses, using AMOS were conducted for 379 respondents as a sample collected. The results show that customer's authority, service training, service reward significantly influenced to competitive advantage. Among the three variables the service reward was especially significant. In addition, competitive advantage significantly influenced to CRM performance (relationship commitment, image of corporation, customer's loyalty). So it is very important for employee to give a authority, share of service training program, give a reward what they want. Because that system can lead to the good performance. As a result, the CEO of hotel has to attention the organizational service orientation for achievement of the CRM performance.
