In Seoul city, The maul-gut(마을굿) called bugundang-gut(부군당굿) have been transmitted by people lived on the banks of han-river. The purpose of this document is to make a study the present meaning of bugundang-gut that have been transmitted in metropolitan city. The bugundang-gut was the official ritual in a government office during the Chosun dynasty. However, the bugundang-gut had been spread along kyunggang(경강, Han-river in Seoul) in the late Chosun period. At that times, the population kyunggang area was increased with the inflow of outside population and the commercial destrict was extended to many district along kyunggang. The main points of this study are as follows. Firstly, I investigate that bugundang-gut have been transmitted by a Seoulite to the backbone. They are the main body of bugundang-gut transmitting from generation to generation. Secondly, I study about nami-janggun-sadangje(남이장군사당제) appointed to seoul city immaterial cutural properties. It is a kind of bugundang-gut. So namijanggun-sadangje was appointed to seoul city immaterial cutural properties, as it was supported by a local autonomous entity. Thirdly, I investigate a plan that can be handed down an offspring in seoul city. We must revise the cultural properties system like that of Japan. Even though many bugundang-gut isn't appointed to cutural propertie except nami-janggun-sadangje, we must recognize their importance and keep a record character of bugundang-gut by investigation in detail. Fourthly, I think that bugundang-gut must be developed a regional public holiday. If it is developed a regional public holiday, many young person can be take part in bugundang-gut.

The purpose of this study was to investigate the actual conditions related to the working environment of radiological technologist who is working in small or medium-sized hospitals or clinics. The results of this study were intended to improve the working environment of radiological technologist and care for patients. For data collection, a structured questionnaire was used as a research tool, and 838 women (52.4%) were used as a general characteristic of 1,598 people subject to this questionnaire. The annual salary of radiological technologists with less than one year experience was 33.76 million won, and the average annual salary of radiological technologists with more than 10 years of experience was 41.33 million won. It showed an increased of 1.84% per year. Among 1,540 radiological technologists, 879 workers were paid holiday work allowances, 340 workers did not, and 321 holiday workers work during the week. In addition, a total of 817 workers received overtime payment, of which 112 received overtime wage on a monthly basis regardless of the overtime hours. In addition, a total of 348 radiological technologists were not paid overtime wage, and 138 workers were included in the basis salary. There were no union in 85% of the them. According to the results of this study, the wages and working environment of radiological technologists in small or medium-sized hospitals or clinics were not appropriate. Therefore, the efforts of the radiological association and its members are necessary to provide a better working environment for radiological technologists. In addition, it is expected that this study will be used as basic data for the association's policy to improve the working environment of members who work in poor conditions.

In the global context, particularly in Christian nations, Christmas is considered a culturally and ethically significant time. In this study, we examine Charles Dickens' novel, "A Christmas Carol," and the celebration of Christmas in Korea. We explore the values of Christmas in Korea derived from the significance and importance of this novel. These values include repentance, empathy, compassion, and the importance of humanity. Korean Christmas is regarded as a time for practicing these values, bearing a message akin to the transformation of characters like Scrooge. Furthermore, "A Christmas Carol" conveys a message of improvement and change over time, emphasizing change and growth in Korean Christmas. People reflect on their past, correct their mistakes, nurture hope for the future, and experience personal growth and transformation. Additionally, the novel raises awareness of social injustice and inequality, offering alternatives. In Korean society, Christmas encourages the willingness to care for and help others, facilitating discussions and understanding of societal issues. For these reasons, "A Christmas Carol" is considered a culturally and ethically significant time in Korean Christmas, and the two are intertwined in various aspects. This study explores the interaction between cultural change and ethical teachings by 'A Christmas Carol' and investigates the impact of this work on Christmas culture and social change. It serves as the basis for emphasizing moral principles and humanity during the Christmas season, and this research provides suggestions for future research directions, aiming to deepen the understanding of Dickens' work and the importance of "A Christmas Carol." Through these efforts, it is expected that valuable insights into the connection between Christmas culture and moral messages will be gained. In this study, we will delve into the enduring appeal and cultural significance of "A Christmas Carol," discussing how this novel has evolved into a beloved holiday tradition and a true symbol of Christmas. We will also examine the adaptation of this novel into various media and its influence on holiday season celebrations. Insights into the impact of this novel on Korean society and its continued significance in modern times will be provided, suggesting a direction for a healthier and more desirable path for Korean society.

The building energy management system (BEMS), a system designed to efficiently manage energy production and consumption, aims to address the variable nature of power consumption within buildings due to their physical characteristics, necessitating stable power supply. In this context, accurate prediction of building energy consumption becomes crucial for ensuring reliable power delivery. Recent research has explored various approaches, including time series analysis, statistical analysis, and artificial intelligence, to predict power consumption. This paper analyzes the strengths and weaknesses of the Prophet model, choosing to utilize its advantages such as growth, seasonality, and holiday patterns, while also addressing its limitations related to data complexity and external variables like climatic data. To overcome these challenges, the paper proposes an algorithm that combines the Prophet model's strengths with the gated recurrent unit (GRU) to forecast short-term (2 days) and medium-term (7 days, 15 days, 30 days) building energy consumption. Experimental results demonstrate the superior performance of the proposed approach compared to conventional GRU and Prophet models.

This study aims to develop an integrated agricultural distribution network management system to improve the quality, profit, and decision-making efficiency of agricultural products. We adopt two key techniques: crop maturity detection based on the YOLOX target detection algorithm and market price prediction based on the Prophet model. By training the target detection model, it was possible to accurately identify crops of various maturity stages, thereby optimizing the shipment timing. At the same time, by collecting historical market price data and predicting prices using the Prophet model, we provided reliable price trend information to shipping decision makers. According to the results of the study, it was found that the performance of the model considering the holiday factor was significantly superior to that of the model that did not, proving that the effect of the holiday on the price was strong. The system provides strong tools and decision support to farmers and agricultural distribution managers, helping them make smart decisions during various seasons and holidays. In addition, it is possible to optimize the distribution network of agricultural products and improve the quality and profit of agricultural products.

This study aimed to determine and examine the contents of vitamins $B_1$, $B_2$, and $B_3$ using the high-performance liquid chromatography method in traditional holiday foods in Korea. All analyses were under the quality control chart of vitamins $B_1$, $B_2$, and $B_3$. The z-scores for vitamins $B_1$, $B_2$, and $B_3$ were 1.3, 0.0, and 0.6, respectively, in food analysis performance assessment scheme proficiency tests assuring reliability of analytical performance. Vitamin $B_1$, $B_2$, and $B_3$ contents were analyzed in a total of 31 samples. Vitamin $B_1$, $B_2$, and $B_3$ contents ranged from 0.000 to 0.973 mg/100 g, from 0.037 to 0.264 mg/100 g, and from 0.000 to 1.223 mg/100 g in Korean traditional holiday foods, respectively. The highest contents of vitamins $B_1$, $B_2$, and $B_3$ were 0.973 mg/100 g in Yukwon-jeon, 0.264 mg/100 g in Dongtae-jeon, and 1.223 mg/100 g in Yukwon-jeon sample, respectively. However, compared to vitamins $B_2$ and $B_3$, vitamin $B_1$ was not detected, generally. Therefore, these results can be used as basic data for a food composition table and improvement of national health for Koreans.

Time series data are influenced by the external events such as holiday, strike, oil shock, and political change, so the external events cause a sudden change to the time series data. We regard the observation as outlier that occurred as a result of external events. In general, it is called intervention if we know the period and the reason of external events, and it makes an analyst difficult to establish a time series model. Therefore, it is important that we analyze the styles and effects of intervention. In this paper, we considered the linear time series model with invention and compared with nonlinear time series models such as ARCH, GARCH model and also we compared with the combination prediction method that Tong(1990) introduced. In the practical case study, we compared prediction power with RMSE among linear, nonlinear time series model with intervention and combination prediction method.

Walking is the first thing an infant wants to do and the last thing an old person wants to give up. Walking is the exercise that does not need a gym. It is the prescription without medicine, the weight control without diet, and the cosmetic that can't be found in a chemist. It is the tranquillizer without a pill, the therapy without a psychoanalyst, and the holiday that does not cost a penny. What's more, it does not pollute, consumers few natural resources and is highly efficient. Walking is convenient, it needs no special equipment, is self-regulating and inherently safe. Walking is as natural as breathing. John Butcher, Founder Walk21, 1999.
