Domestic debates on 'international development' has hitherto been rather more focused on the narrow topic of Official Development Assistance (ODA) - therefore, practical and practice-oriented enquiries for the former's effective implementation have dominated the field as a result. However, such lack of foundational debates on 'development' has rendered the field inept to respond to the rapidly changing development landscape since the new millennium both globally and in Southeast Asia. With this particular problematique in mind, the paper argues for the utility of critical Southeast Asian studies in enriching theoretical debates in Korea's international development studies. In doing so, we analysed the trend of academic research published since 2000, of which theme concern international development with a specific geographical focus on Southeast Asia. The result shows that such publication and the thematic issues have witnessed rapid quantitative growth since 2007 - while the nature of the publications still clearly remained practical and practice-oriented for effective execution of ODA. We therefore propose the critical Southeast Asian studies to overcome the problematique above by emphasising more inter-/multi-disciplinary approaches that challenge the hegemonic paradigm in the field.

Iching has been taught people wisdoms of Sijung since it appeared in oriental society thousands years ago. Sijung means each of us meets the change of the present situation reasonably and practices the timely truth. The current society we've been living is infra-structured by various kinds of visible or invisible networks. This society is called 'network society' which is characteristic of inter-connectivity, interactivity, and complexity, etc. This thesis is to study whether and how the wisdoms of Iching can be helpful for behaviors in network society. For this, the meaning of several hexagrams and the new paradigm of network society were reviewed. Then, which hexagrams give what wisdoms to individuals, organizations, and difficult situations in network society was discussed. In network society, individuals are surfing internet, meeting, chatting, and making groups to implement meaningful works. To these, some hexagrams give wisdoms such as the ethics of rightness, the virtue of the mean. Organizations in network society should rebuild and reform inner suborganizations, cooperate with other organizations including citizen alliances, competing firms, and government organs. To these, some hexagrams give wisdoms such as faithfulness, considerateness, and completeness. Other hexagrams give also wisdoms such as neighborhood, non-selfishness, and self-discipline, to difficult situations lack in communication in network society.

In 2005, Wang et al. discovered devastating collision attacks on the main hash functions from the MD4 family. After the discovery of Wang, many analysis results on the security of existing hash-based cryptographic schemes are presented. At CRYPTO'07, Fouque, Leurent and Nguyen presented full key-recovery attacks on HMAC/NMAC-MD4 and NMAC-MD5[4]. Such attacks are based on collision attacks on the underlying hash function, and the most expensive stage is the recovery of the outer key. At EUROCRYPT'08, Wang, Ohta and Kunihiro presented improved outer key recovery attack on HMAC/NMAC-MD4, by using a new near collision path with a high probability[2]. This improves the complexity of the full key-recovery attack on HMAC/NMAC-MD4 which proposed by Fouque, Leurent and Nguyen at CRYPTO'07: The MAC queries decreases from $2^{88}$ to $2^{72}$, and the number of MD4 computations decreases from $2^{95}$ to $2^{77}$. In this paper, we propose improved outer key-recovery attack on HMAC/NMAC-MD4 with $2^{77.1246}$ MAC queries and $2^{37}$ MD4 computations, by using divide and conquer paradigm.

ESS is an essential requirement for resolving power shortages and power demand management and promoting renewable energy at a time when the energy paradigm changes. In this paper, we propose a cost-effective ESS Peak-Shaving operation plan through load and solar power generation forecast. For the ESS operation plan, electric load and solar power generation were predicted through RMS, which is a statistical measure, and a target load reduction guideline for one hour was set through the predicted electric load and solar power generation amount. The load and solar power generation amount from May 6th to 10th, 2019 was predicted by simulation of load and photovoltaic power generation using real data of the target customer for one year, and an hourly guideline was set. The average error rate for predicting load was 7.12%, and the average error rate for predicting solar power generation amount was 10.57%. Through the ESS operation plan, it was confirmed that the hourly guide-line suggested in this paper contributed to the peak-shaving maximization of customers.Through the results of this paper, it is expected that future energy problems can be reduced by minimizing environmental problems caused by fossil energy in connection with solar power and utilizing new and renewable energy to the maximum.

The Chinese classic 'The Great Learning' presents a guideline in which direction we should go for the character education and the realization of a just society. It conveys the message, 'Everyone must remain at the level of goodness for our community based on training our own mind and body.' Goodness is a generic concept that means universal truth in the right direction. This study aims to present the direction of communication education for how everyone should stay in goodness. Communication education about goodness could be conducted as follows. Based on the theory of interpersonal communication and persuasive communication, first the abstract concept of goodness is understood, brainstorming and schema activity for the good are performed for true communication, and then the teaching and learning method combining debate, flipped learning, and writing could be utilized. It is difficult to provide communication education with the message of goodness with students who have grown up on the basis of comparatively cramming education. However, through communication using discussion, a paradigm shift in education will take place, and it will not only help form human relationships, but also recognize the importance of the meaning of the community in the society in which we live, and ultimately it will help foster character.

The aim of this study was to derive a new trend by analyzing installations using 3D printing that are out of the limits of size and design according to the trends of developing 3D printing technology. This paper classified the types of installations using 3D printing and analyzed them with two trends: the trend of design and the trend of output. The trends of installations using 3D printing derived from this study are as follows. First, as the implementation of design through an algorithm is accomplished, the transformation appears with the atypical design that is prominent in complex expression. Second, Robotics and FDM 3D Printing is fused, which is changing the existing paradigm. Therefore, the production and utilization of installations using 3D printing proceeded at a faster pace through the interaction between the algorithm design method and freeform 3D printing technology. This study was conducted on installations using 3D printing around the world and played a basic role in the research on the production of installations using 3D printing along with domestic 3D printing technology to be developed in the future. Follow-up studies in various aspects, such as materials and combination methods, will be needed.

This study identified the types and dimensions of faculty-student interaction (FSI). A narrative methodology was applied within the qualitative research paradigm. Data was collected using individual in-depth interviews involving 10 students who had experiences of faculty-student interaction more than 6 times over the prior 6 semesters. Data was analyzed according to actors' perspectives, the motivation of actions, and actions toward goal achievement. Three major types of faculty-student interactions emerged from our analysis. First, the initiative interaction type reflects active characteristics of the narrator within FSI and is goal achievement-oriented. Second, the stereotyped interaction was characterized as a unified reaction to the FSI and not significantly related to self-development. Lastly, the reciprocal interaction reflected characteristics of narrators who had potential and flexibility for self-development in the circumstances involving support from professors. The results of this study indicate that faculty-student interaction does not represent the best way to support students for their successful school lives. Faculty needs professionality and sensitivity for student teaching, and students must exhibit curiosity and activeness in developing their knowledge. Positive outcomes from the FSI will be expected in supportive school environments.

The current water-management paradigm is changing from the expansion of reservoirs and facilities for simple outflows and non-point source management to the building of a sound water circulation system throughout the watershed. Based on this, water management for the watershed as a whole is establishing standards through local ordinances. The purpose of this study is to establish water cycle targets that are resilient to water management even after the development of cities in watersheds where water management is highly needed. This was done by referring to research and ordinances related to water circulation by local governments. A method is proposed based on a storage and infiltration method for rainfall. Through a comparison of percentiles, it was found that the water circulation target of a planned waterside city can be treated with 52% of total rainfall and 80% of rainfall of 17 mm per day. To quantitatively improve the quality results of these calculation procedures, it is estimated that the calculation of water cycle targets will be more reliable if other various variables such as the safety of low impact development factors or the selection of appropriate specifications are considered later.

The purpose of the present study is to qualitatively explore childcare teachers' attitudes toward gender sensitivity education for early childhood. The study recruited 227 teachers and directors working in childcare centers around the Seoul metropolitan areas. The study utilised the interpretive science paradigm and visual methods for data collection, and thematic analysis examined the attitudes of 227 participants. Gender sensitivity education include gender flexibility and sexual orientation. Most participants showed positive attitudes toward the gender flexibility education. They regarded the gender flexibility as a topic socially accepted, suitable for early childhood development, and easy to implement. They also believed that the gender flexibility education would encourage the individuality of children. On the other hand, 53.3% of participants showed negative attitudes toward tolerance education regarding sexual orientation. Opponents expressed that an issue of sexual orientation did not reach a social consensus. They also worried that the topic is not developmentally appropriate for early childhood, and difficult to teach young children because of insufficient educational materials. At the same time, 40.5% of participants expected Korean society would embrace diverse sexual orientations in the future, and early childhood education would help young children adapted to changing contexts. This study discussed theoretical concepts of gender sensitivity, listened to childcare teachers' voices about education of gender flexibility and sexual orientation, and suggested more appropriate gender sensitivity education for early childhood.
