With a view to providing a high-quality policy information service beyond the existing national task service of the national policy information portal (POINT) of the National Library of Korea Sejong, it would be necessary to effectively provide the policy data needed for the implementation of the new national tasks. Accordingly, in this study, an attempt has been made to find a way to connect and develop the BRM-based national tasks and the policy information contents. Towards this end, first, the types of national tasks and the contents of each field and area of the government function's classification system were analyzed, with a focus placed on the 120 national tasks of the new administration. Furthermore, by comparing and analyzing the national tasks of the previous administration and the current information, the contents ought to be reflected for the development of contents related to the national tasks identified. Second, the method for linking and collecting the policy information was sought based on the analysis of the current status of policy information and the national information portal. As a result of the study, first, examining the 1st stage BRM of the national tasks, it turned out that there were 21 tasks for social welfare, 14 for unification and diplomacy, 17 for small and medium-sized businesses in industry and trade, 12 for general public administration, 8 for the economy, taxation and finance, 6 for culture, sports and tourism, science and technology, and education each, 5 for communication, public order and safety each, 4 for health, transportation and logistics, and environment each, 3 for agriculture and forestry, 2 for national defense and regional development each, and 1 for maritime and fisheries each, among others. As for the new administration, it is apparent that science technology and IT are important, and hence, it is necessary to consider such when developing the information services for the core national tasks. Second, to link the database with external organizations, it would be necessary to form a linked operation council, link and collect the information on the national tasks, and link and provide the national task-related information for the POINTs.

This study suggests deep neural network models for estimating air temperature with Level 1B (L1B) datasets of GEO-KOMPSAT-2A (GK-2A). The temperature at 1.5 m above the ground impact not only daily life but also weather warnings such as cold and heat waves. There are many studies to assume the air temperature from the land surface temperature (LST) retrieved from satellites because the air temperature has a strong relationship with the LST. However, an algorithm of the LST, Level 2 output of GK-2A, works only clear sky pixels. To overcome the cloud effects, we apply a deep neural network (DNN) model to assume the air temperature with L1B calibrated for radiometric and geometrics from raw satellite data and compare the model with a linear regression model between LST and air temperature. The root mean square errors (RMSE) of the air temperature for model outputs are used to evaluate the model. The number of 95 in-situ air temperature data was 2,496,634 and the ratio of datasets paired with LST and L1B show 42.1% and 98.4%. The training years are 2020 and 2021 and 2022 is used to validate. The DNN model is designed with an input layer taking 16 channels and four hidden fully connected layers to assume an air temperature. As a result of the model using 16 bands of L1B, the DNN with RMSE 2.22℃ showed great performance than the baseline model with RMSE 3.55℃ on clear sky conditions and the total RMSE including overcast samples was 3.33℃. It is suggested that the DNN is able to overcome cloud effects. However, it showed different characteristics in seasonal and hourly analysis and needed to append solar information as inputs to make a general DNN model because the summer and winter seasons showed a low coefficient of determinations with high standard deviations.

This study was conducted to derive a model of the legal system that is the basis for realizing the service economy, political administration, and social education system. Based on the experience of mankind's legal system operation in the historical era for the past 5,000 years, a legal system model that will make the future human society sustainable has been established. The problems of the current legal system were analyzed at the fundamental level. The root cause of injustice and unfairness was analyzed and a new legal system was designed. Through the legal systems of various national societies that have been attempted in the history of mankind, the structure of the legal system that is desirable for the modern society was designed. Human society, which has experienced how much good legal system has been and is being abused by human irrationality and nonsense, needs to make an effort to change the legal system paradigm itself by learning lessons from failure. This study derives the basis for a legal system that can realize justice and a fair society in the long term. It proposed a model for improving the legal system that allows human society to be happy for a long time. To this end, the fundamental role of the legal system was analyzed at the ideological level and the problems of the current legal system were presented. In addition, the problem of fundamental assumptions about human nature was analyzed and improved assumptions were presented. The structural system of the current legal system was analyzed and a new structure was proposed. In addition, a plan for the operation of a new legal system based on a new structure was suggested. The new legal system was named servicism system. This is because it is a model centered on thorough checks and balances between all opponents, not a simple linear one-dimensional legal system, but a multidimensional legal system, and because it is a viewpoint that clearly recognizes both human reason and desire. The new system is a model that reflects the confrontation between the rule of law and the non-law rule and the confrontation between the power people and the general public. A follow-up study is needed on a concrete plan for transitioning from the current legal system to a new legal system.

This is a study of the digital archives of Culturecontent.com where 'Cultural Archetype Contents' are currently in service. One of the major purposes of our study is to point out problems in the current system and eventually propose improvements to the digital archives. The government launched a four-year project for developing the cultural archetype content sources and establishing its related business with the hope of enhancing the nation's competitiveness. More specifically, the project focuses on the production of source materials of cultural archetype contents in the subjects of Korea's history. tradition, everyday life. arts and general geographical books. In addition, through this project, the government also intends to establish a proper distribution system of digitalized culture contents and to control copyright issues. This paper analyzes the digital archives system that stores the culture content data that have been produced from 2002 to 2005 and evaluates the current system's weaknesses and strengths. The summary of our findings is as follows. First. the digital archives system does not contain a semantic search engine and therefore its full function is 1agged. Second, similar data is not classified into the same categories but into the different ones, thereby confusing and inconveniencing users. Users who want to find source materials could be disappointed by the current distributive system. Our paper suggests a better system of digital archives with text mining technology which consists of five significant intelligent process-keyword searches, summarization, clustering, classification and topic tracking. Our paper endeavors to develop the best technical environment for preserving and using culture contents data. With the new digitalized upgraded settings, users of culture contents data will discover a world of new knowledge. The technology we introduce in this paper will lead to the highest achievable digital intelligence through a new framework.

This study was carried out to estimate the contents of heavy metals (Hg, Pb, and Cd) in seaweeds (n=169) which are closely related to food resources. The contents of heavy metals in the laver were found as follows; Hg was highly detected in the east coastal area ($0.0509{\pm}0.0635mg/kg$), Pb in the south coastal area ($0.0509{\pm}0.0635mg/kg$), Cd in the south coastal area ($1.3785{\pm}0.7754mg/kg$). In the sea mustard, Hg was highly detected in the south coastal area ($0.0152{\pm}0.0116mg/kg$), Pb in the east coastal area ($0.1633{\pm}0.2888mg/kg$), Cd in the south coastal area ($0.7141{\pm}0.4952mg/kg$). In the sea tangle, Hg was highly detected in the south coastal area ($0.0177{\pm}0.0118mg/kg$), Pb in the east coastal area ($0.0728{\pm}0.1025mg/kg$), Cd in the south coastal area ($0.1640{\pm}0.1253mg/kg$). In the sea lettuce, Hg, Pb, and Cd were highly detected from the west coastal area. In the fusiforme, Hg and Cd were highly in the west coastal area, Pb in the south coastal area. In general brown algae showed the highest level of Hg, Pb, and green algae showed the highest level of Cd Additionally, the significant correlation was observed between Hg and Cd (r=0.513, p<0.01), between Cd and Pb (r=0.420, p<0.05). The weekly average intakes of Hg, Pb and Cd from seaweeds takes about 0.17~10.30 % of PTWI (Provisional Tolerable Weekly Intakes) that FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.

Ocean currents play the most important role in causing and controlling global climate change. The water depth of the Yellow Sea is very shallow compared to the East Sea, and the circulation and currents of seawater are quite complicated owing to the influence of various wind fields, ocean currents, and river discharge with low-salinity seawater. The Yellow Sea Warm Current (YSWC) is one of the most representative currents of the Yellow Sea in winter and is closely related to the weather of the southwest coast of the Korean Peninsula, so it needs to be treated as important in secondary-school textbooks. Based on the 2015 revised national educational curriculum, secondary-school science and earth science textbooks were analyzed for content related to the YSWC. In addition, a questionnaire survey of secondary-school science teachers was conducted to investigate their perceptions of the temporal variability of ocean currents. Most teachers appeared to have the incorrect knowledge that the YSWC moves north all year round to the west coast of the Korean Peninsula and is strong in the summer like a general warm current. The YSWC does not have strong seasonal variability in current strength, unlike the North Korean Cold Current (NKCC), but does not exist all year round and appears only in winter. These errors in teachers' subject knowledge had a background similar to why they had a misconception that the NKCC was strong in winter. Therefore, errors in textbook contents on the YSWC were analyzed and presented. In addition, to develop students' and teachers' data literacy, class materials on the YSWC that can be used in inquiry activities were developed. A graphical user interface (GUI) program that can visualize the sea surface temperature of the Yellow Sea was introduced, and a program displaying the spatial distribution of water temperature and salinity was developed using World Ocean Atlas (WOA) 2018 oceanic in-situ measurements of water temperature and salinity data and ocean numerical model reanalysis field data. This data visualization materials using oceanic data is expected to improve teachers' misunderstandings and serve as an opportunity to cultivate both students and teachers' ocean and data literacy.

It determines Chinese addiction to piquancy that the Chinese traditional food production laid excessively particular stress on agriculture coming into being long before in the history and the state of Chinese food living was that the people were very difficult to live. The history of Chinese addiction to piquancy could be traced back to prehistory. And in Chinese “hot” is separated from “peppery” and it refers in particular to the piquancy more than general peppery. The character of “Hot” appeared after Han Dynasty in Chinese. Capsicum was brought to China from the sea in the middle of Ming Dynasty. Then it surpassed the formers soon and became the most popular and addictive piquancy food in China. Capsicum has many names in China, such as “$F{\bar{a}}nji{\bar{a}}o$”, “$H{\bar{a}}iji{\bar{a}}o$”, “$L{\grave{a}}ji{\check{a}}o$”, “$L{\grave{a}}h{\breve{u}}$”, “$L{\grave{a}}zi$”, etc., and they indicate the geographical and humanistic character of the distribution. (eight books on preserving one’s health) is the earliest history record about capsicum in existent Chinese history record that was finished in 1591. In this article the author puts new opinion forward on the record in this book. It is because the hottest piquancy of capsicum, capsicum’s better adaptability and low cost to plant combine with Chinese piquancy addiction at large that capsicum can replace the status of pepper and other traditional peppery flavorings soon and cause worldwide attention to the Chinese piquancy addiction finally. The human common characters of unchangeable inertia, depending to fully grow addiction and aggrieved delight are the most important reasons to cause piquancy addiction that has formed a custom through long-repeated practice and this custom do not change with condition change. The unbalanced spread process of capsicum in China shows that the region is poorer and the addictive degree is deeper.

Recently, maintenance engineering and technology for civil and building structures have begun to draw big attention and actually the number of structures that need to be evaluate on structural safety due to deterioration and performance degradation of structures are rapidly increasing. When stiffness is decreased because of deterioration of structures and member cracks, dynamic characteristics of structures would be changed. And it is important that the damaged areas and extent of the damage are correctly evaluated by analyzing dynamic characteristics from the actual behavior of a structure. In general, typical measurement instruments used for structure monitoring are dynamic instruments. Existing dynamic instruments are not easy to obtain reliable data when the cable connecting measurement sensors and device is long, and have uneconomical for 1 to 1 connection process between each sensor and instrument. Therefore, a method without attaching sensors to measure vibration at a long range is required. The representative applicable non-contact methods to measure the vibration of structures are laser doppler effect, a method using GPS, and image processing technique. The method using laser doppler effect shows relatively high accuracy but uneconomical while the method using GPS requires expensive equipment, and has its signal's own error and limited speed of sampling rate. But the method using image signal is simple and economical, and is proper to get vibration of inaccessible structures and dynamic characteristics. Image signals of camera instead of sensors had been recently used by many researchers. But the existing method, which records a point of a target attached on a structure and then measures vibration using image processing technique, could have relatively the limited objects of measurement. Therefore, this study conducted shaking table test and field load test to verify the validity of the method that can measure multi-point displacement responses of structures using image processing technique.

Objectives : The purpose of this study is to investigate the characteristics of patients referred for delirium and depressive disorder and to find direction of improvement of consultation-liason psychiatry in general hospital. Methods : We performed a retrospective computed chart review of the 4,966 inpatients hospitalized at Konkuk University Hospital who were referred to the Department of Psychiatry from August 1, 2005 to December 31, 2011. Results : Depressive disorder shows the order of frequency of consultation type Parallel-Complementary-Mending. Delirium shows the order of frequency of consultation type Mending-Parallel-Complementary. When comparing 'follow up consultation' and 'without follow up consultation' group within the depressive disorder, the proportion of men in the 'follow up consultation' group was higher. In the analysis of the consultation type, the 'follow up consultation' group showed the order of consultation type Parallel-Mending- Complementary, and type Parallel-Complementary-Mending in the 'without follow up consultation' group. When comparing 'follow up consultation' and 'without follow up consultation' group within the delirium, the proportion of the surgical field in the 'follow up consultation' group was higher. In the analysis of the consultation type, both group showed the order of consultation type Mending-Parallel- Complementary. Conclusions : Doctors in each department and psychiatrists should pay attention to delirium symptoms that may occur in surgical inpatients and preventive measures should be taken. Screening tests should be conducted in medical patients to properly evaluate coexisting psychiatric diseases. Risk factors of Delirium and Depressive disorder should be identified from the time of hospitalization, and actively discussing treatment plans and early interventions could improve the quality of medical services.

This paper aims to study on conceptual suitability or unfitness of Silhak(實學). It is general that by criticizing Chujahak(朱子學) or beyond the limitation of Seonglihak(性理學), Silhak has developed practical tendency to reforming the society in the middle and end of Chosen Dynasty, related to the context of Korean national reflection in modern times. However, it is unfortunate to be understood. As presented in Chosenwangjosillok(『朝鮮王朝實錄』), there has been a few usages in the term 'Silhak'. In short, it was different from its contemporary meaning. At that time, it was usually used to have the meaning of Gyunghak(經學), compared to Sajanghak(詞章學), or rarely, of 'the true study' or 'the practical study'. Therefore, it is to claim that its conception has been manipulated or exaggerated very seriously. Since 1930s, in particular, its conception has been misused in interpreting works of Jung Yak-Yong by some scholars, such as Jung In-Bo, Moon Il-Pyung and An Jae-Hong, who tried to apply the term to overcome the Japanese colonial era symbolised as modernity based on the future life of Korea. Even though their attempt has led to have crucial discussions on the conceptions of Silhak, it has an unnecessary result that there has been a new and totally different understanding of Silhak in South Korea, North Korea, China, Japan, etc., which means that the unsustainable conception of Silhak has been one of major problems in studying of Silhak. To give an practical solution, I would try to make sense of 'time spirit' whose scholars studied Silhak in the middle and end of Chosen Dynasty. A problem, however, is that a scholar group in the name of Bukhakpa(北學派) had certain links and bonds. This is because many scholars studying of Silhak were usually features out of the main stream, which made them it difficult to form any various groups. That is to say, it seems to be natural that they have dreamed of utopian imaginations less than of overlapping points in reality. To sum up, it would be concluded at least that any approach to human lives and thoughts in the given conceptions of Silhak, e.g. ethical thoughts of Silhak, enables us to be indifferentiated to take its true meaning and time spirit of Chosen Dynasty. To be disenchanted of its social roles in Chosen Dynasty, fundamentally, it should be escaped from the wrong net of illusions and sings in understanding Silhak in certain eclectic steps.
