This research is to investigate the way to combine Peirce's typology of signs with architectural design. A new diagram is suggested to ensure the continuity of Peirce's typology, by rearranging and reconstructing the well known inverted triangle diagram showing the structure of the typology. The new diagram is easier to understand the organization of the typology, by showing the linkages between sign types and their relationships with other types. A way to adapt the new diagram to architectural design for the purpose of representing typology as well as ensuring model growth as semiotic model for architectural design model. The new model is organized of three sign clusters, sinsign cluster, legisign cluster, and symbolic cluster. They are interrelated through successive inclusion and case inclustion. The new model is organized of threefold layers. The first layer is internal structure of each cluster. The second is interrelation between cluster. The third is mediation of symbolic cluster between sinsign cluster and legisign cluster. This paper investigate and demonstrate the possibility of adaptation of the new model in architectural design. It has been argued that the theoretical basis of sign typology is adaptable to architectural design by principle. More future research issues are discussed.

Objectives : This study was conducted to investigate differences in psychological characteristics between major depressive disorder (MDD) patients with and without suicide attempt using MMPI-2-RF. Methods : Subjects were 107 MDD patients who had visited the department of psychiatry of hallym university hospital and met the DSM-IV diagnostic criteria of MDD by the korean version of MINI-Plus 5.0.0. The patients were divided into suicidal attempters (n=43) and non-suicidal attempters (n=64) using C-SSRS. The one-way ANOVA was used to compare MMPI-2-RF scale scores between two groups. Additionally, ANCOVA was conducted considering the severity of depressive symptom and comorbidity as covariate. Results : Our results showed that Suicide/Death Ideation (SUI), Inefficacy (NFC) and Interpersonal Passivity (IPP) scales were significantly higher in the MDD patients with suicidal attempt compared to MDD patients without suicidal attempt (p<0.05). However, after controlling for the severity of depressive symptom and comorbidity, SUI scale showed a significant tendency (p<0.10). Conclusions : The result suggests that MMPI-2-RF scales could be a useful tool for identifying patients transitioning to actual suicidal attempts in the moderate or severe major depressive disorder group. Limitations of this study and directions for further research are also discussed.

Whenever a mineshaft accidentally collapses, speedy risk assessment is both required and crucial. But onsite safety diagnosis by humans is reportedly difficult considering the additional risk of collapse of the unstable mineshaft. Generally, drones equipped with high-speed lidar sensors can be used for such inspection. However, the drone technology is restrictively applicable at very shallow depth, failing in mineshafts with depths of hundreds of meters because of the limit of wireless communication and turbulence inside the mineshaft. In previous study, a three-dimensional (3D) scanning system with a single channel lidar was fabricated and operated using towed cable in a mineshaft to a depth of 200 m. The rotation and pendulum movement errors of the measuring unit were compensated for by applying the data of inertial measuring unit and comparing the similarity between the scan data of the adjacent depths (Kim et al., 2020). However, the errors grew with scan depth. In this paper, a multi-channel lidar sensor to obtain a continuous cross-sectional image of the mineshaft from a winch system pulled from bottom upward. In this new approach, within overlapped region viewed by the multi-channel lidar, rotation error was compensated for by comparing the similarity between the scan data at the same depth. The fabricated system was applied to scan 0-165 m depth of the mineshaft with 180 m depth. The reconstructed image was depicted in a 3D graph for interpretation.

The deterioration of underground facilities, disturbance of the ground due to underground development activities, and changes in ground water can cause ground subsidence accidents in the urban areas. The investigation on the geotechnical and hydraulic factors affecting the ground subsidence accident is very significant to predict the ground subsidence risk in advance. In this study, an analysis DB was constructed through 3D ground modeling to utilize the currently operating geotechnical survey information DB and ground water behavior information for risk prediction. Additionally, using these results, the relationship between the actual ground subsidence occurrence history and ground conditions and ground water level changes was confirmed. Furthermore, the methodology used to visualize the risk of ground subsidence was presented by reconstructing the engineering characteristics of the soil presented according to the Unified Soil Classification System (USCS) in the existing geotechnical survey information into the internal erosion sensitivity of the soil, Based on the result, it was confirmed that the ground in the area where the ground subsidence occurred consists of more than 40% of sand (SM, SC, SP, SW) vulnerable to internal erosion. In addition, the effect of the occurrence frequency of ground subsidence due to the change in ground water level is also confirmed.

Korea is recognized as the most advanced nation in regards to capabilities or environments of informatization throughout the world. Nevertheless, Korea brings on itself such stigmas as a nation vulnerable to information security. Now the globe ushered in an era requiring political balances. Yet, issues of legislative supports or system adjustments for information security policies are always pushed back on the priority list. There is a need to face problems at the center of changes departing from such frames. In order to establish a proper system for information security policies, the most urgent issues are reviews of concepts and reorganizations of systems, and then to legislate information security polities by being harmonious with public opinions. This paper is to remind what measures are needed to improve the system of priority policies depending on public backgrounds and why such measures are needed. Furthermore, the paper suggests a new legislation, 'Information Security Policy Act' as one of the specific measures.

This study is on teaching about the areas of plane figures through open instruction, which aims to discover the pedagogical meanings and implications in the application of open methods to math classes by running the Math A & B classes regarding the areas of parallelogram, triangle, trapezoid and rhombus for fifth graders of elementary school through open instruction method and analyzing the educational process. This study led to the following results. First, it is most important to choose proper open-end questions for classes on open instruction methods. Teachers should focus on the roles of educational assistants and mediators in the communication among students. Second, teachers need to make lists of anticipated responses from students to lead them to discuss and focus on more valuable methods. Third, it is efficient to provide more individual tutoring sessions for the students of low educational level as the classes on open instruction methods are carried on. Fourth, students sometimes figured out more advanced solutions by justifying their solutions with explanations through discussions in the group sessions and regular classes. Fifth, most of students were found out to be much interested in the process of thinking and figuring out solutions through presentations and questions in classes and find it difficult to describe their thoughts.

As a background for qualitative research, the concept of bricolage is very common in the North America. As a movement of art area, because, it has characteristics of criticality and existence which is very close to the definitions of qualitative research. However, regardless of recent rapid wide-spread of qualitative research with the world trend of research methodology, it is very unusual that scholars are rarely discussing on the concept of bricolage in South Korea. In literature review, scholars conceptualize bricolage in literature, art, and so on except qualitative research field. Thus, I realize that it is necessary to discuss the concept of bricolage in qualitative research. Through it, scholars will understand more about the definition of qualitative research. Accordingly, I try to prove the thesis 'qualitative research is bricolage' in this article. In conclusion, scholars commonly define qualitative research to involve the meanings of 'reflection', 'understanding', 'deconstruction', and 'reconstruction' and illustrate also the concepts of bricolage in a praxis of interpretation and understanding with getting together of rigorousness, complexity, and criticality. I realize that these notions are very close to each other in this study.
