In this paper, I examined specific characteristics of the Tables of Transactions for Records Scheduling(TRS) (記錄物分類基準表 ; Kirokmul-Bulyukijun - Pyo) system by Public Records and Archives Act(PRA Act, No. 5709, 1999). All staffs and employees in governmental agencies of Korea must register, classify and dispose of their official records according to TRS by the Presidential Regulation for the application of PRA Act(No. 17050, 2000). Namely, the criteria of TRS is applicable to all stages of records lifecycle from creation to disposition(transfer to Archives or legal destruction). In the theoretical and methodological area, therefore, it is absolutely important that records managers and archival professionals in Korea make analysis on functions and characteristics of TRS by PRA Act. In the first, my examination take notice of possibility of 'adequate and proper documentation' about activity of the executive organization in TRS system. Other attention is that records management according to TRS means managing of records not only as physical entities but as logical entities which imply content and context of creation and use. In other hand, I wish to account for reasonable separation consideration for continuing utility of archives from current use of records throughout agencies duration Another theme of discussion in this paper is the theoretical framework which give account of TRS's characters. In conclusion, accountability for characteristics of TRS system could have been found in counterproposal view including the concept of Records continuum and the notion of Recordkeeping regime in Australia based on rethinking about Records lifecycle model. In the extent of practical area, more or less, it is imbalanced method that compare TRS by PRA Act to Recordkeeping regime based on Records continuum. Nevertheless, the concept and notion is suitable framework that give account of the prospect of recordkeeping system under PRA Act.as well as the meaningful characteristic of TRS.

The goal of this study is to analyze the value of Kanga as an ethos of the Swahili culture. The theoretical background of the research method was the analysis of the domestic and foreign literature, journals, and research data from various internet sites related to the subject, and the conclusion was drawn based on these studies. With the spread Pan-Africanism, the interest in African ethos has become a source of inspiration for contemporary fashion. Moreover, as a symbol of Swahili culture in East Africa, Kanga has been developed by embracing its own diverse cultures, The unique feature of Kanga is that it can easily be transformed created ceaselessly and creatively. Consequently, the following results were obtained based on the theoretical content. Firstly, as a representative of Women's Voice, Kanga serves as an outlet for the voices of women coming from a poor social status under the political background in East Africa. Secondly, as a Reliable Advocate, Kanga performs the positive functions as a medium of communication through its traditional usage and distinctive arrangement of clothes. Thirdly, as a Versatile Messenger, the uniqueness of Kanga with the external elements in most interestingly and active mannerly, and it has become the value of communication channel which clearly inspired the fashion designers. I believe that it will be interesting and meaningful to study the strategies on the social role of Kanga in the future which has started receiving more attention in the 21st century. And it can be said that Kanga's unique identity lies in the attraction and value which influences contemporary fashion.

This study is a follow-up paper on "Development of flipped learning class model for nail beauty education" published by Seol (2022). This model was conducted from March to June 2022 for 70 students taking the "Nail color design 1" course. After 15 weeks of class, a survey of the students' perceptions of flipped learning and their self-evaluation of goal achievement was conducted, which was composed of questionnaires using a 5-step Likert scale. 15 questions were designed to evaluate the students' satisfaction with their experience and class operations; 4 questions to evaluate whether the class goal had been reached through flipped learning; and 9 questions to evaluate the students' perceptions of flipped learning. As a result of applying this model to theoretical and practical nail beauty classes, it was confirmed that flipped learning helped students better understand the content and had a positive effect on learning, while the subject's educational goals were also achieved. By evaluating the students' perceptions of flipped learning, we may conclude that they experienced learning satisfaction and perceived the approach positively. Moreover, they have expressed a desire for additional flipped learning. This study is thus meaningful in confirming the procedure's effectiveness by applying the flipped classroom model to theoretical and practical subjects with a focus on the nail beauty field, and showing how it achieved students' positive perceptions and educational goals.

This study aims to understand science education conducted in North Korea by analyzing the PCK components shown in two science teacher's guidebooks: (1) Guidebook for 1^st grade elementary school and (2) Guidebook for 1^st grade middle school. These were published after 2013, when "the first 12-year Universal Compulsory Curriculum" was implemented in North Korea. The analysis shows that both elementary and middle school guidebooks had the highest percentage of content in "Knowledge of Subject Matter", followed by "Knowledge of Instructional Strategies in Science" and "Knowledge of Science Curriculum". On the other hand, "Knowledge of Assessment in Science" and "Knowledge of Students" were significantly low in content. Within the "Knowledge of Subject Matter", both elementary and middle schools had the highest proportion of content in "Concepts and Theories", along with "Experiments and Inquiries" that was also significantly higher than other PCK components. Science teacher's guidebooks in North Korea advocates constructivist teaching style by using "discussions" as the main activity when conveying scientific concepts and theories to students or conducting scientific inquiry classes. Furthermore, "Knowledge of Instructional Strategies in Science" was mainly focused on guiding the "Instruction sequence and method" from the "Topic-specific Strategies", while only a small part of the "Subject-specific Strategies" was being presented. Also, Science teacher's guide books in North Korea included only a few theoretical elements of science education in both the general outline and the particular sections of guidebooks. "Knowledge of Science Curriculum" was mainly composed of "Lesson Objectives" with some inclusion of "Vertical Articulation" and "Horizontal Articulation". "Knowledge of Assessment in Science" and "Knowledge of Students" accounted for a small portion compared to the science teacher's guidebooks in South Korea.

This study aims to clarify the nature and properties of multimedia interface design, and to identify direction of multimedia interface design research. It also focuses on forecasting boundaries and major trends in current researches on multimedia interface design. The two jargons, 'interface' and 'interaction', are distinguished clearly to show the definition and boundary of multimedia interface. The multidisciplinary nature of multimedia interface design is identified as a result of examination and analysis on major researches. Nine research cases have been selected and categorized into two directions as the theoretical approach and the technical approach. Major characteristics of each case are examined in terms of subjects and methodologies. Findings on current states of the multimedia interface design research are: $\circled1$increasing importance of contextuality; $\circled2$emerging tendency for perceiving the content as one of interacting subjects; $\circled3$providing idiomatic interface context; and $\circled4$paying much attention to the meaning of minor actions. Those findings can be possible as a result of expansion of boundary of multimedia content with rapid distribution of multimedia in recent years. The study concludes that further researches can be activated on the basis of the concept of content-based multimedia interface.

Analyzing textbook is the first step for enhancing the level of biology education especially in Korea. Prior studies of textbook analysis have mostly dealt with such topics as terminology analysis, content analysis, relationship analysis of chapters, and comparative studies. However, not much attention was paid to concept system to be learned and to relevance of concepts chosen. Therefore, the purpose of this study is to clarify the concept system and to elucidate the relationship among concepts for effective learning. Novak's concept map was utilized as a theoretical framework for the analysis of chapter I of high school biology textbook. Concept map has several distinctive merits in many aspects such as teaching, learning, and evaluation. It not only makes the understanding of key concepts and proposition a lot easier, but also helps to link prior knowledge and new concepts more effectively. This study will be a basic material for improving textbook for effective biology learning. The conclusions of the study are as follows: 1. Concepts in subchapters were arranged unsystematically or they were overlapping. For more effective understanding, those items should be rearranged. 2. Key concepts are not arrayed properly according to their hierarchy. Therefore, it was hard for students to set up concept structure. 3. The concepts emphasized by bold letters were not selected properly in accordance with their importance. Appropriate concepts should be chosen. 4. Key concepts should be explained by using examples in everyday life for easy understanding. 5. Many concepts in molecular biology is too abstract to grasp their meaning. Therefore, many audio-visual materials should be used to aid concept building.

The aim of this study was to develop and validate measures of a mother's reaction to children's negative emotions. After construct factors of a mother's reaction to children's negative emotions based on the theoretical basis and existing scales were explored, the first preliminary items were extracted. After the content validity was confirmed by expert opinions, the second preliminary items were composed, and the initial survey was carried out. Using exploratory factor analysis, three principal factors and 21 items were revealed to be most suitable. The factors of the scale consist of emotion-coaching-reactions, oversensitive reactions, and emotion-minimizing-reactions, respectively. In addition, the reliability analysis and validation analysis of the scale was conducted, by means of surveying 413 elementary students. The internal coherence reliability and test-retest reliability were verified as was the general internal coherence and timing stability of the scale. There were three additional verifications to validate the scale. (1)For the evidence based on internal structure, the confirmatory factor analysis and convergent-discriminant evidence; this resulted in confirming the factor structure of the scale as being reliable. (2)In order to understand the relationships to other variables, the correlation analysis came in effect to the overall scale and each of its sub-factors, showing that they are significantly correlated with the scale of the child's perception on rearing attitudes of the mother. (3)As for evidence based on the consequences of the test, the correlation analysis produced a result showed that sub-factors of the scale have as significant correlation with the child's emotional intelligence and resilience.

To evaluate the safety status of deteriorated segments in a submarine shield tunnel during its service life, a seepage model was established based on a cross-sea shield tunnel project. This model was used to study the migration patterns of erosive ions within the shield segments. Based on these laws, the degree of deterioration of the segments was determined. Using the derived analytical solution, the internal forces within the segments were calculated. Lastly, by applying the formula for calculating safety factors, the variation trends in the safety factors of segments with different degrees of deterioration were obtained. The findings demonstrate that corrosive seawater presents the evolution characteristics of continuous seepage from the outside to the inside of the tunnel. The nearby seepage field shows locally concentrated characteristics when there is leakage at the joint, which causes the seepage field's depth and scope to significantly increase. The chlorine ion content decreases gradually with the increase of the distance from the outer surface of the tunnel. The penetration of erosion ions in the segment is facilitated by the presence of water pressure. The ion content of the entire ring segment lining structure is related in the following order: vault < haunch < springing. The difference in the segment's rate of increase in chlorine ion content decreases as service time increases. Based on the analytical solution calculation, the segment's safety factor drops more when the joint leaks than when its intact, and the change rate between the two states exhibits a general downward trend. The safety factor shows a similar change rule at different water depths and continuously decreases at the same segment position as the water depth increases. The three phases of "sudden drop-rise-stability" are represented by a "spoon-shaped" change rule on the safety factor's change curve. The issue of the poor applicability of indicators in earlier studies is resolved by the analytical solution, which only requires determining the loss degree of the segment lining's effective bearing thickness to calculate the safety factor of any cross-section of the shield tunnel. The analytical solution's computation results, however, have some safety margins and are cautious. The process of establishing the evaluation model indicates that the secondary lining made of molded concrete can also have its safety status assessed using the analytical solution. It is very important for the safe operation of the tunnel and the safety of people's property and has a wide range of applications.

Tests for transient water release and imbibitions measurement were conducted to estimate the unsaturated hydraulic conductivities by using back analysis. By using transient hydraulic characteristics, both the soil water retention curve and hydraulic conductivity fuction can be evaluated effectively and accurately. In this study the experiment for three samples were conducted accurately to measure the change of water content with time for various steps of matric suction. The back analysis calculated the amount of transient flow reliably in comparison with the experimental results. In the soil water retention curve there was no significant difference between the result of back analysis and that of experiment. The hydraulic conductivity function from back analysis was compared with the theoretical relation based on retention curve but they showed much difference. However, the unsaturated hydraulic behavior obtained by the combination of experimental and analytical techniques are considered to agree with the actual behavior.
