The objectives of this study are to define the fundamental notions of collaboration in design field. The results of this study are summarized as follows: Firstly, collaboration means a cooperative work which are cooperatively done by collabarator and collaboratee on the equal status within a certain period of time, based on core ability of each of them. This cooperative work is presented with a visual image based on the identity of participants, and it creates an added value. Collaboration is different from convergence and hybrid in the methodological aspects and from brand alliance and strategic alliance in the aspects of the subject of project. Secondly, collaboration has been developing through step of using the specific ability, step of sharing each core abilities, and step of fusing their identities, in a view of the sphere of cooperative work and the intimate relations in reciprocity. Thirdly, according to strategic purpose, collaboration can be classified into value ascending collaboration, image changing collaboration, business-field extension collaboration, and event collaboration. Fourthly, production methods of collaboration consist of limited edition method, premium line method, common line method, producing a collaborative product, and so on. Fifthly, differentiation effect, image upgrade effect, production of higher value-added products, sale increase, diversification of business, sharing the targets, and promotion effect are achievable through collaboration. Sixthly, to make progress in collaboration successfully, the compatibility of combination between collaborator and collaboratee, the superiority of collaboratee, definitude of collaboration, the fit method of collaboration, the novelty of collatoration, possibility of issuing of collaboration, and perfection of collabo-product must be the points which deserve our attention.

This study aimed to conduct an eye-tracking experiment carried with facade images as a medium and to do research on 'the interest of the eyes' resulted from people's gazing phenomena. This study secured gazing data which appeared according to visual response and analyzed gazing phenomena to find the basic theory of 'the interest of the eyes' as a methodological role, which consumer interest and attention could be grafted when a plan and a design for space design was made. Data terms used in eye-tracking backgrounds and the movement of the eyes were investigated in literature review. Twenty (20) facade images were selected through a case study to get experimental stimuli for the related experiment. Thirty (30) subjects (men and women) suitable for the experiment were recruited to conduct an eye-tracking experiment. After the experiment, five (5) areas were set up in the facade image to identify the focus level of interest and attention. The level of interest and focus was connected to the interest of the eyes. The analysis to study the interest of the eyes was based on nine (9) items such as sequence, entry time, dwell time, hit ratio, revisits, revisitors, average fixation, first fixation and fixation count. Through gaze analysis, the following conclusion was drawn about the 'interest level of sight' for gaze frequency. The interest level can be interpreted to be higher for faster sequence, shorter entry time, longer all fixation(ms) for dwell time, faster all saccade(%), higher hit ratio, more revisits, more revisitors, longer average fixation, faster and longer first fixation, and more fixation count, and the person can be said to have felt interest faster and/or more.

For a successful construction project, the requirements of the client should be clearly defined and this should be reflected in the project based on the expertise of each project participant throughout the entire life-cycle. Therefore, it is necessary to establish the concept of Requirements Management to systematize and manage project requirements in terms of information management. This study aims to comprehensively define the concept of requirements management in the architecture industry and to provide a methodological basis for efficiently managing design requirements information by suggesting category of requirements information type and information analysis criteria. In addition, based on the case study, the requirements information was analyzed to propose a systemization methods of requirements management for PMO' design management and information management.

Since the late 1980's, the number of research papers published in the Journal of the Korean Society of Costume(JKSC) has increased. The JKSC is usually known for its focus on issues relevant to the aesthetics of dress, fashion design, and the history of Western or Oriental dress. The main goal of this paper is to link the academic importance of the fashion marketing field to the expansion of the journal and society. First, we defined the scope of the fashion marketing field, based on a literature review and general practices of other competitive societies and journals. First, we reviewed the curricula of the fashion marketing field from 49 universities in Korea. Next, we examined the research topics and methodology of 271 papers in the fashion marketing field published in JKSC since its first issue in 1977. By comparing the findings from the curricula and research, we drew conclusions for the fashion marketing field of the journal and society. We found that the approximately 80% of the fashion marketing courses provided at the undergraduate level are related to merchandise planning and selling processes from the company perspective. However, in more than 85% of the research papers, consumer characteristics and decision-making processes were the main focus and were used as key variables. These findings imply that more various methodological approaches are required for the research to enrich the theoretical background which, in turn, can support curricular development in fashion marketing field. The fashion marketing field in JKSC and society should make the most of accumulated knowledge in product design, symbolic aspects of fashion, and the qualitative approach in the research topics of the JKSC and society.

This study investigates Korean consumers' general perception on brand authenticity, tests the influences of authenticity determinants on the evaluation of fashion brand authenticity and compares the influences in terms of brand category (luxury/non-luxury). A three-stage methodological approach was adopted: (1) A literature review identifies authenticity determinants and generates measurement items. (2) A preliminary study uses a quantitative survey (n=50) to purify the determinants. (3) A quantitative consumer survey (n=150) identifies general perceptions on brand authenticity by measuring the perceived relevance of brand authenticity on determinants and explores the influence of determinants on authenticity evaluations using purified measurements of authenticity determinants. The results of general perception on brand authenticity show that Korean consumers deem authentic brands as honest, sincere and socially responsible. The results indicate obvious differences between luxury and non-luxury brands towards the influence of perceived authenticity determinants (genuine, consistent, original, traditional and authoritative) on authenticity evaluation of luxury/non-luxury brands. In non-luxury brands, only 'genuine' and 'consistent' have significant effects that are similar to the results of the general perception on brand authenticity. However, only 'consistent' and 'authoritative' have significant effects for luxury brands and are different from the general perception.

Presence, flow, and arousal are interesting user experiences provided by video and people's demand for media which responds to personal interest is getting strong. This research compares video watching and game play by conducting a survey and measuring brain wave to find out the difference of those user experiences in the two media. As a result, all the three user experiences were proved to be significantly higher in game play than video watching. And those EEG frequencies which are known to be related to the state of flow were also measured higher scalp distribution of the game play group. Finally, presence, arousal, and EEG(${\alpha}$, ${\beta}$, ${\delta}$) were found to have influence on the flow state in game play. This research is intended to prove above relations by experiment and make a contribution to the theoretical and methodological improvement in the related area.

The controversy over the risk of the human body being affected by electromagnetic fields emitted from 60 Hz power lines continues without end. There are currently no new studies or research progress being made in this direction that is notable, and the number of civil complaints is gradually increasing. The problem is that each study produces different results, among which the effect of exposure to magnetic fields on childhood leukemia is a major one. In Korea, an electrician who was maintaining a 22.9 kV power line died of leukemia, which has recently been recognized as an occupational disease. Methods to reduce magnetic fields from power lines include shielding with wire loops, incorporating split phases and compaction techniques, installing underground power lines, converting to high-voltage direct current (HVDC), and increasing the ground clearance of transmission towers. Depending on whether a separate power supply is needed or not, there are two types of wire loops: passive loop and active loop. Magnetic field reduction is currently done through underground power lines; however, the disadvantage of this process is high construction costs. Installing passive loops, with relatively low construction costs, leads to lower magnetic field reduction rates than installing underground cables and a weakness to not solving the landscape problem. This methodological study aims at designing methods and reducing the effects of 2-wire set loops-the simplest and most practical. Since the method proposed in this study has been designed after analyzing the distribution of complex electromagnetic fields near the expected loop installation location, a practical design can be implemented without the need for any difficult optimization programming.

The purpose of this study was to synthesize intervention studies, which utilized single case experimental design, on teaching mathematical word problems for elementary school students with disabilities and evaluate each of their methodological rigor. The researchers reviewed all studies from 2000 to 2022 that involved teaching mathematical word problems to individuals with disabilities. A total of 12 studies was included for a final analysis. Most of the interventions were delivered by researchers for about 30-40 minutes per session to elementary school students with disabilities. Schema-based instruction, cognitive-metacognitive strategy, and technology-based instruction were used as intervention methods, and explicit instruction was mostly used in conjunction with them. On the other hand, the researchers found that none of research articles met quality indicators for single case experimental design according to Cook et al. (2015). Limitation and directions for future research were also discussed.

Today, the principles of green chemistry are being fundamentally applied in the chemical industry, such as the nitrobenzene industry, which is an essential intermediate for various commercial products. Research on the application of response surface methodology (RSM) to optimize nitrobenzene synthesis was conducted using a sulfated silica (SO₄/SiO₂) catalyst and batch microwave reactor. The nitrobenzene synthesis process was carried out according to RSM using a central composite design (CCD) design for three independent variables, consisting of sulfuric acid concentration on the silica (%), stirring time (min), and reaction temperature (℃), and the response variable of nitrobenzene yield (%). The results showed that a three-factorial design using the response surface method could determine the optimum conditions for obtaining nitrobenzene products in a batch microwave reactor. The optimum condition for a nitrobenzene yield of 63.38 % can be obtained at a sulfuric acid concentration on the silica of 91.20 %, stirring time of 140.45 min, and reaction temperature of 58.14 ℃. From the 20 experiments conducted, the SO₄/SiO₂ catalyst showed a selectivity of 100 %, which means that this solid acid catalyst can potentially work well in converting benzene to nitrobenzene.
