A Study on Utilization of IoT for Remote Piano Concerto in China

This paper proposed a measure for utilizing an IoT-based piano concerto system with no spatial constraints. To accomplish the goal, this paper referred to previous research and related material to examine the theoretical background and problems. Then, this paper suggested improvements for the IoT system. The contemporary piano concerto often adopts new techniques instead of using traditional ones to accentuate the individuality of the performer. As a result, there needs to be enough discussion and practice with orchestra members for a successful performance. To solve this problem, this paper proposed on utilizing an IoT-based system. This paper suggested on improving the existing IoT system, developing the sensors to hear the instrument sound better, and upgrading the hardware by adding the server transmission feature to the sensor. This paper also suggested delivering more accurate sound by correcting the sound with software in china.
Pre-Service Teachers' Expectations and Evaluations of Childcare Practice

The purpose of this study is to find out what pre-service teachers' expectations and positive and negative evaluations of childcare practice are. The participants of the study were 48 4th grade students majoring in child psychology and education. The survey was conducted before and after childcare practice. As a result of frequency analysis of the responses, expectations for childcare practice were 96 responses in 6 categories, of which ‘career aptitude exploration’ was the most frequent. As for the evaluations of childcare practice, the positive evaluations were 69 responses in 9 categories, of which ‘emotional interaction with children’ was particularly frequent. And the negative evaluations were 75 responses in 20 categories, of which ‘physical fatigue’ was the most frequent. This study suggests that pre-service teachers expected to learn a lot and acquire values from the practice, but they experienced more negative aspects than positive aspects in the practice process. The results of this study can be used as a basis for finding ways to improve the efficiency of childcare practice.
Harvestable Metadata Services Development: Analysis of Use Cases from the World Data System

Minimally, a research data repository exists to make a collection of data assets available to potential users. If a dataset cannot be discovered and found, it cannot be reused (Garnett et al. 2017). Harvestable metadata catalogues are a key strategy for achieving greater global findability of data assets, as they create a surveyable access point to discover data products within large data collections. Such catalogues can be especially effective if they are tailored for interoperability with feature-rich infrastructures (e.g. meta-catalogues, see Kapiszewski &amp; Karcher 2020; CRFCB 2014) that are highly visible and widely used, and also themselves integrated within the larger ecosystem of research infrastructures. This study offers insight into a set of World Data System (WDS) research data repositories ongoing and successful implementations of harvestable metadata services, which apply established and emerging research data standards and practices to fit global, local and domain-specific interoperability contexts. Establishing a harvestable metadata service involves making choices in a space where standards and technologies are continuously evolving. The repositories in this study leverage the resources they have, within the policy and funding constraints of their institution, to serve the changing needs of heterogeneous user groups. This document encapsulates and completes the work that was carried out by the WDS International Technology Office (ITO) Harvestable Metadata Services Working Group (HMetS-WG).
Cultural Exchange and Dual Degree Program Directions between Mekong River Basin Countries and Korea: Focused on Vietnam

Both Korea and Vietnam belong to the same traditional Eastern cultural sphere and share common cultural and religious backgrounds, including Confucianism and Buddhism. This results in shared values like family importance, etiquette and education. Their cultures, influenced by China, exhibit a sense of homogeneity. However, differences exist between the two countries, notably in food culture, language, and the habits of lifestyle. It is crucial for effective cultural and human exchanges to recognize these differences. The mutual exchanges between universities in Korea and Vietnam are increasing recently, promoting promote academic exchanges and human resource development. The dual degree program between universities of the two countries notably contributes to cultivating global talented men. This program allows students to acquire academic knowledge from both cultures, enhancing global competence. The study proposes to outline the operation of such a program.
A Study on the Relationship between Program Format and Leadership of Entertainment Program Main MC

Recently, each platform is expanding the programming of entertainment programs, which are the core of the format industry and increase viewer ratings, but while the diversity of materials and performers has increased, the diversity of formats has decreased. After 2000, entertainment programs, centering on star MCs, have repeatedly produced programs of similar formats that can make use of their characteristics and strengths, leading to stagnation and regression in format diversifi cation. In the process of analyzing this phenomenon, this study paid attention to the fact that the leadership and characteristics of the main MC of an entertainment program have a great influence on other performers and programs, in particular, have a deep correlation with the composition and change of the program format. Therefore, by analyzing the leadership of the main MC and exploring the correlation between it and the program format, it is expected to serve as a cornerstone for related research and serve as an opportunity to change the fixed and repetitive format.

A study on the need for a PMC(Project Management Consultant) to achieve Large Scale Project Performance: Focusing the case of PMC: applied construction projects

Recently, global construction companies are turning to PMC, a high value-added business. However, domestic construction engineering companies are still conducting projects focused on detailed design and construction supervision. This study aims to investigate the necessity of introducing PMC by analyzing the cases of completed projects in which PMC was introduced among domestic construction projects. Among the large-scale national projects in Korea, examples of the application of global standard PM include nuclear power plant projects in the 1970s, Gyeongbu High Speed Rail, Incheon International Airport, Incheon Bridge and Yongsan United States Forces Korea Base Relocation Plan (YRP) projects. However, these projects are PMC projects carried out by advanced global companies in Korea. There is an implication in that the necessity of introducing PMC for the successful completion of large-scale national projects was analyzed through the case analysis of these projects.
Consideration of Publishing Governance to Revitalize the Book Culture Ecosystem

This study examined the publishing governance for the revitalization of the book culture ecosystem, and proposed a plan by analyzing its characteristics and problems, focusing on the composition of the board of directors of the KPIPA. In order to revitalize book culture, an ecological perspective that solves problems from an integrated perspective and organic connection of various actors in the ecosystem must be applied, and it is sustainable with the cooperation of various members of the ecosystem. As a result of the study, first, the board of directors is composed mainly of publishing organizations and publishers. Second, there is no participation of various stakeholders from the perspective of the book culture ecosystem, such as authors, publishers, bookstores, libraries, and readers. Third, the composition and operation of the board of directors is male-dominated, and as a public institution, it does not comply with the Gender Equality Act. Fourth, there is a structural problem with the regulations of the executive nomination committee in the articles of incorporation of the KPIPA. Fifth, the Ministry of Culture, Sports and Tourism, which is responsible for changing bad governance to good governance and cooperative governance, failed to properly fulfill its role as a mediator.
A Study on Learning Trajectory Design for Develop Students’ Reasoning of Sampling Variability

Our understanding of statistical inference is based on our understanding of the concept of sampling variability. In this study, we aimed to explore learning trajectory that would help students meaningfully construct concepts related to sampling variability under this assumption. For this purpose, in this study, based on hypothetical learning trajectory theory, we designed a learning trajectory that is expected to develop students’ reasoning about sampling variability. We qualitatively analyzed the results of a teaching experiment conducted for a group of preparatory teachers according to the guidance of the learning trajectory designed in this study. As a result, The participants were able to generate the hypothesis that sample medians obtained through a random sampling process were normally distributed around the population median. The participants were then able to generate the hypothesis that the larger the sample size, the smaller the range of distribution of the sample median. Furthermore, it is possible to generate the hypothesis that the center of the distribution of the sample median is determined by the population median, and the range of the distribution of the sample median is determined by the sample size and the interquartile range of the population. In addition, based on the results of retrospective analysis of the difference between the hypothetical learning trajectory and the actual learning trajectory, we proposed a modification of the initially designed hypothetical learning trajectory.
Decomposition Analysis of Changes in Greenhouse Gas Emissions of Domestic Major Companies that have Declared Carbon Neutrality

탄소중립 목표를 설정하는 국내 기업들이 증가하고 있다. 탄소중립을 선언한 국내 주요 기업들, 즉 포스코, 현대제철, 삼성전자, LG화학, SK이노베이션 계열, 롯데케미칼, 현대자동차의 ESG(환경, 사회, 지배구조) 통계 자료를 활용하여 2019~2021년 기간의 온실가스 배출량 변화 요인을 분석하였다. 방법론은 로그 평균 디비지아 지수(Logarithmic Mean Divisia Index, LMDI) 분해분석법을 이용하였다. 분석 대상 7개 기업 가운데 온실가스 배출량이 2019년 대비 감소한 기업은 5개 기업이었다. 배출량이 감소한 5개 기업의 경우, 에너지집약도 효과가 4개 기업의 배출량 감소에 영향을 미쳤으며, 배출집약도 효과는 3개 기업의 배출량 감소에 영향을 미쳤고, 매출 효과는 1개 기업의 배출량 감소에 영향을 미쳤다. 온실가스 배출량이 2019년 대비 감소한 5개 기업 중에서 2개 기업의 배출량 감축 수준은 자사의 탄소중립 목표를 달성하기 위한 감축노력 수준을 상회하고 있었다. 온실가스 배출량이 2019년 대비 증가한 기업은 2곳이었으며, 배출량 증가 추세로부터 탄소중립 경로로 전환하기 위해서는 에너지집약도 개선과 배출집약도를 저감하기 위한 노력을 동시에 강화할 필요가 있다. An increasing number of domestic companies are setting carbon neutral targets. Using the ESG (Environmental, Social, Governance) statistical data of domestic major companies that have declared carbon neutrality, namely POSCO, Hyundai Steel, Samsung Electronics, SK innovation affiliates, LG Chem, Lotte Chemical, and Hyundai Motor, the factors of change in greenhouse gas emissions from 2019 to 2021 are analyzed. The Logarithmic Mean Divisia Index (LMDI) decomposition analysis method is used. Among the companies analyzed, there were five companies whose greenhouse gas emissions decreased compared to 2019. In the case of these five companies, the energy intensity effect affected the emission reduction of 4 companies, the emission intensity effect affected the emission reduction of 3 companies, and the sales effect affected the emission reduction of 1 company. Among these five companies, two companies" emission reduction level was exceeding the level of reduction efforts to achieve their targets. There were two companies whose greenhouse gas emissions increased compared to 2019. In order to shift from the trend of increasing emissions to a carbon-neutral path, it is necessary to simultaneously strengthen efforts to improve energy intensity and reduce the emission intensity.

This paper introduces a method based on enhanced 3D point cloud model and 3D point cloud comparison algorithm for the calculation of volume and density features of traditional Chinese medicine decoction pieces, which provides reference for clinical medication safety. The algorithm strengthened the 3D point cloud model generated by multiple two-dimensional pictures, and calculated the volume of Chinese herbal decoction pieces by using the 3D point cloud comparison algorithm, and then obtained the density of Chinese herbal decoction pieces. This method was an innovation in the identification of Chinese herbal pieces. The average relative error of the calculated sample volume and density was less than 6.5% and 5.9%.
Photon Coincidence Simulation Through a Random Splitting of Virtual Photon Timestamps

The single-photon nature and the purity of emitted photons from a light source can be quantified using the second-order correlation function, g <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(2)</sup> (τ). Here, we present simulation results that show how the photon coincidence time window, a characteristic of the utilized photodetection system, affects g <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(2)</sup> (0) for dummy photon timestamps digitally generated at constant emission rates. We use a two-channel virtual interferometer with a beam splitter controlled by a uniform random number selection. We find that g <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(2)</sup> (0) remarkably and quickly squeezes towards the maximum value of a chaotic light photon correlation as the coincidence time window widens. In contrast, tuning the coincidence time window close to the emitter emission decay time yields a coincidence probability of slightly less than one, an antibunching property of light. These simulation findings can participate in improving measurements of quantum light emitters’ coherence functions and revealing the degree of their photon emission purity.

Lastly, top management need to be firmly committed to supporting service standardization. Based on this research
Visualization of Objects in Mobile Messenger Conversations

From a conversation analytic perspective, this study explores the phenomenon of the visual representation of referenced objects in KakaoTalk conversations. KakaoTalk is a mobile messenger application designed for the exchange of text messages, but participants frequently use images to refer to various ontological categories such as people, places, and objects. This technology-enabled practice, characterized as the visualization of referents, was examined through 14 sets of KakaoTalk conversations, with a focus on objects. I first show how objects are represented visually, usually in combination with written text. An analysis of the interactional contexts in which this occurs further shows that the visualization of objects is used to deal with lack of information, to share entities of mutual interest, to seek validation of everyday events, and to invite agreement on a physical aspect of an entity. It is argued that object visualization occurs in and through sequentially unfolding interaction, distinguishing it from image sharing on other social media platforms.

University English Speaking Program Evaluation and Improvement

The present study attempted to improve an English conversation program at a local university in Korea through rigorous evaluation. A total of 382 students completed a closed-ended survey with six categories: program goals and strengths, student needs, teaching, materials, assessment, and suggestions for improvement. Twenty-two teachers also completed an open-ended survey with the same categories. Teachers reported that the program’s greatest strength was teaching the English language and cultures, whereas students indicated its strengths were offering opportunities to communicate in English, learning pronunciation, and gaining confidence in speaking. Regarding the students’ needs, the teachers pointed out that they were lacking in speaking ability and confidence, whereas students wanted to improve daily life English conversational skills and have more opportunities to practice these skills. For class activities, students preferred games, visual materials, 1:1 conversation with a native teacher, and paired work. With respect to textbooks, both teachers and students reported that the current textbooks were not appropriate. Regarding assessment, students preferred to be marked on attendance, participation, learner attitude, assignments, quizzes, and midterm and final exams. Both teachers and students made suggestions for improvement. A clearly written curriculum for the conversational program was systematically devised based on these findings.
The Effect of Authentic Leadership on Job Satisfaction: Moderating Effect of Leader Trust
