  • This study is an analysis on the focus of textbooks regarding the statistical chapters of "measures of representative(central tendency) and of the spread". Applying the summary-concept criteria of Juhyeon Nam(2007), 4 kinds of aspect of the chapter; (1) definition and its teleological validity of the measures of representative, (2) definition and practical value of the measures of spread (3) distributional form on the measures of representative and of spread (4) location and scale preservation or invariance of the measures of representative and of spread were observed. On the measures of representative, some definitions were insufficient to check the teleological validity of the measure. Most definitions of the measure of spread were based on the practical view points but no preparation for the future statistical inferences were found even by implication. Some books mention about the measures of representative and of spread for distributions, but we could not find any comments on the correspondence between the sample mean and the expectation of a distribution or population mean. However it is stimulant that some books check the validity of corresponding measures with the location and scale preservation or invariant property, that were not found in the previous curriculum.

  • The purpose of this study is to analyze the mathematical connection components of the tasks included in the trigonometric ratio unit of 3rd grade middle school textbook based on the 2015 revised mathematics curriculum and investigate teachers' perceptions and practical measures regarding these components. To this end, we analyzed the characteristics of mathematical connection tasks included in the trigonometric ratio units in nine types of 3rd grade middle school mathematics textbooks, and we conducted a questionnaire survey and interviews with one in-service math teachers in pre interview and with two in-service math teachers in this interview to investigate their perceptions and practical measures. As a result of the study, the number of tasks with external connection in the trigonometric ratio unit were less than those of internal connection. In addition, in terms of teachers' perceptions and practical measures, the perspective of analyzing tasks with mathematical connections varied depending on the teacher's perspective, and the practical measures varied accordingly. These findings are significant in that they reveal the relationship between mathematical tasks, teacher perceptions and measures to foster effectively students' mathematical connections.

  • Background: Safety management is required to ensure health and safety of personnel in Norwegian fish farming. However, few studies have addressed the status and practical relevance of this risk-reducing measure. Methods: This article provides new knowledge through interviews with 35 employees at different company levels, addressing perceptions of various safety management activities according to managers and operational personnel. Results: The interviews show that managers and operational personnel at fish farms agree that the quantity of measures aimed to improve safety has increased in recent years. However, some activities are perceived to have higher practical relevance than others. In general, measures that fit well with the practical reality are well received by the employees at the fish farms. Conclusion: Suggested improvements include involving operational personnel in the design of procedures, considering all risk dimensions that may affect occupational health and safety, and challenging the value of specific safety activities based on a detailed knowledge of the distinctive characteristics of work practice in fish farming.

  • Korea enacted the Protection of Public Interest Reporters Act in March 2011 to protect whistleblowers from acts of infringement of public interest in the private sector. Most acts of infringement of the public interest are carried out secretly within the organization, which is known to the outside world by reports from members of the organization who are well aware of the problems within the organization. However, whistleblowers are at a disadvantage due to reporting and are reluctant to report. In addition, measures are needed to strengthen institutional mechanisms such as confidentiality, protection of personal information, responsibility, and prohibition of disadvantageous measures to effectively protect reporters due to lack of practical protective measures. Therefore, practical protection measures for whistleblowers are needed in line with the purpose of protecting whistleblowers, and measures to expand the corresponding compensation system will also be needed. Therefore, in this study, we would like to review the main contents of the current system for protecting whistleblowers in Korea and suggest reasonable improvement measures for protecting whistleblowers.

  • This study aims to extract key topics through text mining of incident records (incident history, post-incident measures, preventive measures) from construction safety accident case data available on the public data portal. It also seeks to provide fundamental insights contributing to the establishment of manuals for disaster prevention by identifying correlations between these topics. After pre-processing the input data, we used the LDA-based topic modeling technique to derive the main topics. Consequently, we obtained five topics related to incident history, and four topics each related to post-incident measures and preventive measures. Although no dominant patterns emerged from the topic pattern analysis, the study holds significance as it provides quantitative information on the follow-up actions related to the incident history, thereby suggesting practical implications for the establishment of a preventive decision-making system through the linkage between accident history and subsequent measures for reccurrence prevention.

A Study on the Binding Power of Interim Measures and the Effect of Interim Measure Non-Compliance in ICSID Arbitration (ICSID 중재의 임시적 처분 구속력과 미준수 효과에 관한 연구)

  • This study focuses on the binding power of the interim measures of the arbitral tribunal in ICSID arbitration and the effects of non-compliance. Upon consideration of the intentions of those who made these rules, given the interpretation of the provisions of Article 47 of the ICSID Convention and Article 39 of the ICSID Arbitration Rules, it was found reasonable to consider that the interim measures made by the arbitral tribunal in ICSID arbitration were not binding. However, in actual ICSID arbitration, most arbitral tribunals approve the binding power of the interim measures based on the purposes and the characteristics of the interim measures. As such, there is a certain distance between the legislative intention for interim measures in ICSID arbitration and the judicial practice, but considering the demand for maintaining the integrity of the arbitration procedure, it is reasonable to consider that the interim measures are binding. In addition, the fact that the interim measures have binding power can increase the possibility that the party will comply with the interim measures. Thus, the binding power of interim measures not only encourages voluntary compliance to the interim measures of the party, but can also cause negative consequences for the party if it is not met. In other words, the arbitral tribunal will be able to form negative inferences against the party who does not comply with it in a procedural side, and in the practical side, the party who does not comply with the interim measures will be compensated for the additional damages for non-compliance.

  • This study aims to suggest the values and utilization measures of the stone walls in Jeju Island as place assets. The discussion on this subject may serve as a breakthrough to resolve the current situation where the stone walls in Jeju Island have been focused on for their potential value not for their practical value as place assets. Moreover, specific measures to utilize Jeju stone walls may become a vehicle to seek the sustainable development of the region. This study discussed the types, functions and values of the stone walls in Jeju Island as place assets and suggested practical measures to use the structures based on their regional distribution. The in-depth discussions largely concluded that there might be five values and seven utilization measures with regard to the Jeju stone walls. The results of the study are expected to be utilized as a new indicator for the regional development of Jeju Island.
