. This study investigated the preservation and succession of the temple culture of making jang in Buddhist temples across the country. A self-administered questionnaire was distributed to 117 temples. The questionnaire included queries with respect to general information, ingredients for preparing jang, difficulties, and processes of making jang, and the various types of jang. Of the temples surveyed, 35.9% made their own meju. Most of the temples(99.1%) used sea salt to make brine. Also, 67.5% of the temples used groundwater or mineral water, and 65% of the temples used a method of floating eggs in the brine and using buoyancy to measure salinity. Most of the temples(95.7%) added supplementary ingredients such as charcoal, dried pepper, and dried jujube. In 63.2% of the temples, monks directly supervised the process of making jang, and 85.5% began making jang in the first lunar month. The meju was separated from jang within 60 days in 43.6% of the temples. Among the temples surveyed, 40.1% boiled liquid(ganjang) and stored it after separating it from the solid(doenjang), while the rest stored it as raw ganjang without boiling. The results of this study can be used as basic data for research on traditional Korean jang, which could include documenting temple jang recipes and conducting additional research.

This paper deals with the consensus problem for multi-agent linear dynamic systems with directed communication topology. All the agents are identical high-order linear systems and their state information is exchanged through a communication network with directed graph. It is shown that a consensus is achieved if there exists a feasible solution to a set of linear matrix inequalities obtained for a simultaneous stabilization problem for multiple systems. Examples are presented to show the effectiveness of the proposed method.
확산 모형에 의한 첨단 영상진단 의료기기 수요확산의 특성 분석 및 수요예측에 관한 연구

Objectives: In this study, we explore the demand forecasting of Advanced Diagnostic imaging Equipment. Methods: The analysis was based on logistic diffusion model. We analyze the specific pattern of each equipment’s diffusion curve by interpreting the parameter estimates of logistic diffusion model. Results: Our findings are follows. First, Computed tomography is in the stage of saturation and so, the future demands of that is not too large. Second, Magnetic resonance imaging (MRI) is expected that it will take about 5 years to reach saturation, and further growth is expected to continue. Third, Positron emission tomography (PET) has been shown to be saturated, and therefore, it is not expected that there will be a rapid increase in demand in the future. However, since demand data has been declining since 2000, it is said that additional data collection is required to reliably predict future demand. Conclusions: As a result of analyzing the demand for three major advanced diagnostic imaging equipment, it was found that the domestic market is generally in saturation. Therefore, a future research task will be to predict and analyze the demand for advanced diagnostic imaging equipment in consideration of the government’s policy changes. .

. Objectives: This paper proposed the direction of future supply and demand management policies through demand prediction and demand character- istics analysis of advanced diagnostic imaging equipment using new medical technology. Methods: This study used the Bass Diffusion Model to analyze demand characteristics for advanced diagnostic imaging equipment. Derived diffusion coefficients were applied for medium to long-term demand pre- dictions (2021-2050). Parameter estimation employed non-linear regression analysis (SPSS 27.0). Demand characteristics were further analyzed using the ratio of the Bass model’s innovation to imitation coefficients for each country and device. Results: Comparing the imitation coefficients (q/p ratio) for computed tomography (CT) and magnetic resonance imaging (MRI) among South Korea, the United States, and Japan, South Korea has the highest q/p ratio for both CT and MRI. This implies that the influence of opinion leaders and group pressure is relatively more significant in South Korea, particularly in CT purchases. In the demand prediction results, South Korea’s q/p ratio for CT and MRI is notably larger, suggesting that institutional pressures and col- lective decision-making, rather than individual clinical decisions, play a significant role in the purchase of advanced diagnostic imaging Equipment. The q/p ratio for advanced diagnostic imaging Equipment in South Korea is higher than in other countries, reflecting a large power distance in the adoption of these technologies. Conclusions: This study utilizes the Bass Diffusion Model to predict the demand for advanced diagnostic imaging equipment in South Korea, Japan, and the United States. Findings highlight that imitation, not innovation, is the main driver of diffusion, with South Korea showing a faster adoption rate for CT and MRI. The study identifies factors influencing diffusion in South Korea, noting the impact of the quantity system on CT and the absence of influence on MRI. CT diffusion is positively linked to the quantity-based payment system, while MRI remains unaffected.
사이버 치과 진료 상담을 통해 살펴본 구강내과 질환의 중요성에 대한 고찰

The moderners of industrial society suffer from various stresses, which bring about increase in prevalence of temporomandibular disorders, oral mucosal disease and chronic neuropathic pain, therefore, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to discuss the importance of oral medicine related disease by investigating questions that appeared in cyber consultation of Kangnung National University Dental Hospital web site. Among the nearly 2000 questions, the rate of questions related to oral medicine was 20.92%, and the rate of questions related to other departments were oral and maxillofacial surgery 16.87%, conservative dentistry 16.67%, orthodontics 14.02%, prosthodontics 12.25%, periodontics 8.36%, pediatric dentistry 4.93%, preventive dentistry 2.08% and otherwise questions 3.90%. Among the 403 questions related to oral medicine, the frequent questions were oral mucosal diseases 44.17%, temporomandibular disorders 41.19%, halitosis 4.47%, xerostomia 3.23%, other orofacial pain 2.23%, forensic dentistry 1.49% and otherwise questions 2.98%. From the higher rate of questions related to oral medicine compared with other fields of dentistry, we would consider that the people are considerably concerned about the oral medicine related disease, such as oral mucosal diseases and temporomandibular disorders.
