Innovation and change are occurring rapidly in the agriculture and livestock industry, and new technologies such as smart bams are being introduced, and data that can be used to control equipment is being collected by utilizing various sensors. However, there are various challenges in the operation of bams, and virtual sensor technology is needed to solve these challenges. In this paper, we define various data items and sensor data types used in livestock farms, study cases that utilize virtual sensors in other fields, and implement and design a virtual sensor system for the final smart livestock farm. MBE and EVRMSE were used to evaluate the finalized system and analyze performance indicators. As a result of collecting and managing data using virtual sensors, there was no obvious difference in data values from physical sensors, showing satisfactory results. By utilizing the virtual sensor system in smart livestock farms, innovation and efficiency improvement can be expected in various areas such as livestock operation and livestock health status monitoring. This paper proposes an innovative method of data collection and management by utilizing virtual sensor technology in the field of smart livestock, and has obtained important results in verifying its performance. As a future research task, we would like to explore the connection of digital livestock using virtual sensors.

The purpose of this study is to investigate the academic librarians' perception of the current status and establishment of the development plans of domestic university libraries to suggest ways to increase usefulness of development plans. And this study sought ways to establish the academic library development plan that reflected the key components of the development plan. To this end, a survey was conducted on academic library librarians, and in-depth interviews were conducted with the persons in charge of the academic library development plan to supplement the limitations of survey. The results are as follows. First, the establishment of academic library development plans tend to be formal and passive, and has limitation in eliciting cooperation between external organizations and academic libraries. Second, most academic libraries do not disclose their development plans on their websites. Third, the awareness of the leaders of the academic library organization needs to be preceded, and a task force needs to be formed to establish development plan. As a result of the study, it is suggested that 'active changes in the perceptions and operation method within academic libraries', 'external disclosure of development plans and strengthening cooperation', and 'strengthening the initiative and role of librarians' are needed as improvement measures.

Text augmentation is a methodology that creates new augmented texts by transforming or generating original texts for the purpose of improving the performance of NLP models. However existing text augmentation techniques have limitations such as lack of expressive diversity semantic distortion and limited number of augmented texts. Recently text augmentation using large language models and few-shot learning can overcome these limitations but there is also a risk of noise generation due to incorrect generation. In this paper, we propose a text augmentation method called TAGS that generates multiple candidate texts and selects the appropriate text as the augmented text. TAGS generates various expressions using few-shot learning while effectively selecting suitable data even with a small amount of original text by using contrastive learning and similarity comparison. We applied this method to task-oriented chatbot data and achieved more than sixty times quantitative improvement. We also analyzed the generated texts to confirm that they produced semantically and expressively diverse texts compared to the original texts. Moreover, we trained and evaluated a classification model using the augmented texts and showed that it improved the performance by more than 0.1915, confirming that it helps to improve the actual model performance.

In an era where construction projects are becoming increasingly large and complex, the Korean construction industry faces the challenge of implementing systematic and cohesive schedule management practices. This study initially delineates the concept of schedule management capabilities, systematically categorizing them into five distinct domains: law and regulations, requirements of project owners, capabilities of professionals and organizations, task capability, and the adoption of smart construction technologies for schedule management. Through a survey targeting industry professionals, this research assesses the perceived importance and the actual proficiency level in schedule management across these categories, employing an Importance Performance Analysis(IPA) to scrutinize these capabilities. The findings underscore the acknowledged significance of diverse aspects of schedule management, yet reveal discrepancies between the current proficiency levels and their perceived importance, pinpointing areas necessitating enhancement. Critical improvement needs identified encompass the planning of budgets for schedule management, development of regulations for assessing construction periods, deployment of specialized on-site staff for schedule management, and investment in advanced schedule management software solutions. Consequently, this study offers a nuanced analysis and strategic insights for enhancing schedule management practices, aiming to facilitate their effective implementation in the field.

The purpose of this study is to analyze domestic academic library development plans, check whether key components are reflected, and seek ways to improve the establishment of academic library development plans. To this end, a rubric evaluation technique derived from research related to evaluation of foreign universities and libraries was used. The libraries of the top 15 domestic universities were selected by referring to the QS World University Evaluation and THE World University Evaluation as the subjects of the study, and how much the core components of the development plan were reflected were evaluated. The results of the study are as follows. First, as a result of evaluating the university library development plan, most of the contents of 'purpose', 'goal', and 'action plan' were reflected, but vulnerabilities were found in 'mission' and 'vision'. Second, some private academic libraries were moving toward strategic planning at the level of advanced countries, including all of the core components. Third, although most academic libraries specified 'purpose', it showed limitations due to perfunctory description and connection. In the comprehensive evaluation, out of the highest score of 15, 12 were good and 3 were poor, indicating that the development plans of domestic academic libraries were generally at a 'good' level. As an improvement measure, it was suggested to form a task force for development plan establishment, to disclose and promote development plans, and to strengthen education on development plans for librarians.

This research discusses how to improve the current environment for record management in relation to the Revision of the Law of Record Management in South Korea. Three major issues are: 1) Legal status of the National Archives & Records Service of Korea as the government institution in charge of managing centrally records, 2) System for the education and training of professionals who specialize in record management, and 3) Foundation of the national museum and archives of records. Findings are as follows: First, the existing 'National Office of Records' as the government institution in charge of managing records, should be promoted to the 'National Archives & Records Service of Korea' in order to be administered by the class of a vice-minister in the Ministry of Government Administration and Home Affairs. Second, the qualification criteria which currently requires the Master's degree of Record Management, should be modified to include the Bachelor's degree in the field in order to expand the pool of professional human resources. Also, to hire the public officials for record management, either the positions of 'researcher/record manager group' should be created, or the existing positions of librarian, archivist, and record manager should be integrated into the new position of 'record culture group'. Third, the most significant task for the office of record management of local governments is to inherit and further develop the traditional culture and documentary legacy which are unique to those local communities and governments at various levels, and a priority should be given to those tasks. Therefore, when the Law of Record Management will be later revised, the establishment of the office of record management for local governments at every level should be required, and the museum and archives of records should be also established as a significant part of the institution. Unique local culture and history of particular communities should be collected and preserved in systematically specialized and differentiated ways in those institutions of record management, and the names should be uniquely given to the institutions according to the characteristics of local governments.

It is becoming more essential than ever for office professionals to become competent in information collection/gathering and problem solving in today's global business society. In particular, office professionals do not only assist simple chores but are also forced to make decisions as quickly and efficiently as possible in problematic situations that can end in either profit or loss to their company. Since office professionals rely heavily on their tacit knowledge to solve problems that arise in everyday business situations, it is truly helpful and efficient to refer to similar business cases from the past and share or reuse such previous business knowledge for better performance results. Case-based reasoning(CBR) is a problem-solving method which utilizes previous similar cases to solve problems. Through CBR, the closest case to the current business situation can be searched and retrieved from the case or knowledge base and can be referred to for a new solution. This reduces the time and resources needed and increase success probability. The main purpose of this study is to design a system called COKRS(Case-based reasoning Office Knowledge Recommender System) and develop a prototype for it. COKRS manages cases and their meta data, accepts key words from the user and searches the casebase for the most similar past case to the input keyword, and communicates with users to collect information about the quality of the case provided and continuously apply the information to update values on the similarity table. Core concepts like system architecture, definition of a case, meta database, similarity table have been introduced, and also an algorithm to retrieve all similar cases from past work history has also been proposed. In this research, a case is best defined as a work experience in office administration. However, defining a case in office administration was not an easy task in reality. We surveyed 10 office professionals in order to get an idea of how to define a case in office administration and found out that in most cases any type of office work is to be recorded digitally and/or non-digitally. Therefore, we have defined a record or document case as for COKRS. Similarity table was composed of items of the result of job analysis for office professionals conducted in a previous research. Values between items of the similarity table were initially set to those from researchers' experiences and literature review. The results of this study could also be utilized in other areas of business for knowledge sharing wherever it is necessary and beneficial to share and learn from past experiences. We expect this research to be a reference for researchers and developers who are in this area or interested in office knowledge recommendation system based on CBR. Focus group interview(FGI) was conducted with ten administrative assistants carefully selected from various areas of business. They were given a chance to try out COKRS in an actual work setting and make some suggestions for future improvement. FGI has identified the user-interface for saving and searching cases for keywords as the most positive aspect of COKRS, and has identified the most urgently needed improvement as transforming tacit knowledge and knowhow into recorded documents more efficiently. Also, the focus group has mentioned that it is essential to secure enough support, encouragement, and reward from the company and promote positive attitude and atmosphere for knowledge sharing for everybody's benefit in the company.

Purpose: The purpose of this study was to provide the basic information on the improvement plan by identifying the role accomplishment and job satisfaction of the hospice nurses and analyzing the factors that impact such role accomplishment and job satisfaction. Methods: The data was collected of 189 hospice nurses who have been working more than 6 months in 56 hospice programs registered in Korea Hospice Association and Korean Catholic Hospice Association from October to November, 2007 by structured questionnaire which was developed by Ryu(1979), based on the Riehl's nursing role and the research of Choe(2005) on the role of hospice nurse. Results: The role accomplishment and job satisfaction of the study subject were 3.53 point and 3.39 point, respectively. The roles of hospice nurses were accomplished by the order of advocator, nursing care provider, coordinator (cooperation), educator, quality manager, counsellor, administrator, and researcher. The job satisfaction of the hospice nurses was shown highest in the satisfaction of professional status, followed by the satisfaction of the interaction, satisfaction of the task itself, satisfaction of the administrative aspect, satisfaction of the autonomous, and the lowest in the satisfaction of the pay. The role accomplishment of the subjects according to their socio-demographic and job characteristics was found to have a significant difference by their age, marriage status, academic background, and position. It also has a significant difference by whether they play role of coordinator, whether they took whole responsibility as hospice, working experience as hospice/palliative nurse, and the level of hospice/palliative nursing training(p<.05). In the study of job satisfaction of the subjects according to their socio-demographic and job characteristics, the job satisfaction was found to have a significant difference by the increase of age, the number of duties consisting the hospice team, whether they play role of coordinator, whether they take whole responsibility as hospice, the level of hospice/palliative nursing training, and whether they wish to work for as long as possible(p<.05). The role accomplishment and the job satisfaction of the subjects showed a statistically significant positive correlation. (r=.541, p<.01) Conclusion: Raised saiary will be increased hospice nurse's job satisfaction. And we suggest a repetitive study using the identical tool to the equally extracted subjects with same representativeness of each hospice/palliative institute type. For the expanded role and enhanced professional standard of hospice nurses, we also suggest a study on the improvement plan to enhance the roles of researcher and administrator.

"Financial ADR" system in South Korea can be represented by so-called "Financial Dispute Resolution System", in which Financial Supervisory Service (FSS) and Financial Dispute Resolution Committee are the principal actors in operation of the system, and this is discussed as an "Administrative Financial ADR System". The system has over 10-year history since it was introduced in around 1999. Nonetheless, it was not until when financial consumer protection began to be highlighted after the 2008 financial crisis that Financial ADR system actually started to draw attention in Korea. This was because interest has been rising in "Alternative Dispute Resolution (ADR)" as an institutional measure to protect financial consumers damaged via financial transactions. However, the current discussion on the domestic Financial ADR system shows an aspect that it is confined to who is to be a principal actor for the operation of Financial ADR institution with main regards to reorganization of supervisory system. This article aims to embody these facts in an institutional model by recognizing them as a problem and analyzing the features of the Financial ADR system, thereby clarifying problems of the system and presenting the direction of improvement. The Korean Financial ADR system can be judged as "administrative model integrated model consensual model quasi-judicial model non-prepositive Internal Dispute Resolution (IDR) model". However, at the same time, it is confronted with a task to overcome the two problems; the system is not equipped with institutional basis for securing its validity in spite of the adopted quasi-judicial effect model; and a burden of operating an integrated ADR system is considerable. From this perspective, the article suggests improvement plans for security of validity in the current system and for expansion of industry-control ADR system, in particular, a system of prepositive IDR model. Amongst them, it suggests further plans for securing the validity of the system as follows; promotion to expand the number of internal persons and to differentiate mediation procedures and effect; a plan to keep a financial institution from filing a lawsuit before an agreement recommendation or a mediation proposal is advised; and a plan to grant suspension of extinctive prescription as well as that of procedures of the lawsuit.

Purpose: The objective of this study is to suggest desirable direction of Korean accident investigation organization by analyzing the operation status and way of overseas developed countries' investigation agency. Method: To accomplish the objective of this study, we were examined four main characteristics of accident investigation agencies of the U.S., Japan, and Sweden, focusing on (1); the background of the establishment, (2);organizational structure, (3);major tasks and functions, (4); accident investigation procedures. Result: First, the purpose of its establishment and task is to prevent recurrence of disasters and accidents, at the same time, administrating and researching duties such as legal system, policy, recommending improvement and conducting scientific disaster-cause analysis to contribute safety for the government. Second, it is operated as an independent organization under the president, not belonging to the ministry, in order to enable fair investigation in an impartial position. Third, it has the authority to be recognized for its expertise in the results of investigation. In other words, it is operated as a permanent organization with professional personnel, and secures authority through the accident research with indepth investigation and high-quality recommendations. Conclusion: The overseas investigation agencies rapidly manage and coordinate their operational practices in order to resolve national requirements and social conflicts with fairness, accuracy and expertise in accident investigations. In order to prevent the recurrence of similar events, Korea needs to efficiently reconstruct its investigative functions distributed by each government department. In addition, institutional improvement is needed to make general adjustments at the national level, organize and operate control tower for when the accident has happened.
