  • Recent years have seen a notable increase in fire incidents in university cafeterias, yet the social attention to these occurrences remains limited. Despite quick responses to these incidents preventing loss of life, the need for large-scale evacuation in such high foot traffic areas can cause significant disruptions, economic losses, and panic among students. The potential for stampedes and unpredictable damage during inadequate evacuations underscores the importance of fire safety and evacuation research in these settings. Previous studies have explored evacuation models in various university environments, emphasizing the influence of environmental conditions, personal characteristics, and behavioral patterns on evacuation efficiency. However, research specifically focusing on university cafeterias is scarce. This paper addresses this gap by employing Pathfinder software to analyze fire spread and evacuation safety in a university cafeteria. Pathfinder, an advanced emergency evacuation assessment system, offers realistic 3D simulations, crucial for intuitive and scientific evacuation analysis. The studied cafeteria, encompassing three floors and various functional areas, often exceeds a capacity of 1500 people, primarily students, during peak times. The study includes constructing a model of the cafeteria in Pathfinder and analyzing evacuation scenarios under different fire outbreak conditions on each floor. The paper sets standard safe evacuation criteria (ASET > RSET) and formulates three distinct evacuation scenarios, considering different fire outbreak locations and initial evacuation times on each floor. The simulation results reveal the impact of the fire's location and the evacuation preparation time on the overall evacuation process, highlighting that fires on higher floors or longer evacuation preparation times tend to reduce overall evacuation time.In conclusion, the study emphasizes a multifaceted approach to improve evacuation safety and efficiency in educational settings. Recommendations include expanding staircase widths, optimizing evacuation routes, conducting regular drills, strengthening command during evacuations, and upgrading emergency facilities. The use of information and communication technology for managing emergencies is also suggested. These measures collectively form a comprehensive framework for ensuring safety in educational institutions during fire emergencies.

  • Purpose: The purpose of this study is to examine the risks and criminal progress of pig murder fraud crimes in the absence of related research and statistics amid a surge in pig murder fraud damage in Korea, and to approach the methods, problems, and countermeasures that can be prevented in Korea through foreign cases. Method: In order to classify the types of pig murder fraud crimes, the progress was analyzed through related reports and statistics, and various damage cases. Result: The crime of pig murder fraud can be seen as an organized crime that organically combines simple romance scams, investment fraud, and human trafficking. In the case of victims, unlike simple fraud, psychological problems such as suicide impulse and panic disorder were found, and in the case of cryptocurrency acquired through fraud, a path was found to flow back into the criminal organization through money laundering. Conclusion: In the case of pig murder fraud crimes that have been detected as a danger worldwide, the scale will be even wider. Therefore, various institutional supplements and policies should be prepared through crime type analysis in Korea for crime prevention and countermeasures.

  • The purpose of this study is to understand more deeply the life of a woman with mental disabilities who experienced divorce through oral data analysis and to derive a therapeutic plan. Women with mental disorders diagnosed with depression and panic disorder participated in the study, and the text for life history analysis consisted of oral data interviews. Based on the life history analysis framework proposed by Mandelbaum (1973), the text was analyzed into three conceptual frameworks: 'Dimensions', 'Turning point', and 'Adaptation'. As a result of data analysis, the 'Dimensions' was analyzed as "Abandoned child", "The onset of mental illness", "Religion", and "Crime". In the 'Turning point' analysis, "Divorce" and "Life separation" were analyzed, and "Adaptation" was derived as "Rationalization". Based on the results of this study, a therapeutic intervention plan was proposed for the life of a female mentally disabled woman who has experienced divorce.

  • The technology of 'Virtual Reality' has placed in advanced tools for human beings' joy and anger together with sorrow and pleasure in our generation. It has recently tried in a variety ways to use as an implication for treatment in the field of Cognitive Psychology. Especially, it widely approaches to human in terms of that a sense of reality in a virtual world through the five senses should reinterpret the meaning of cognition in the real world. Based on this paradigm shift, it allows for new treatment using the technology of virtual reality. A typical example is a field of Therapy in order to overcome panic disorder. It has advantages that in particular development of flexible interaction technologies in a virtual space can lead patients to experience psychological environments rather than physical one. the interaction technology provides environments in which users' five senses can be actively stimulated, it is very useful that information from the experiences in the virtual world allows people to learn through real experiences by renewing potential energies, advantages of Virtual Reality Therapy can be customized treatment by depending on symptoms in patients with panic disorder and are capable of differentiate application for the cure at each stage. It is to treat by leading patients to get accustomed to environments and situations in real world through care process with each symptom and stage. It is helpful that based on A Human-Sensibility Ergonomics, technologies like immersive virtual reality equipment, force-relative feedback and stereophonic sound, and like stimulating the sense of smell make people to induce experiences by stimulating human's five senses. There are many advantages of immersion in virtual world in that the phenomenon such as challenge, interaction, reality, illusion, and cooperation is expanded. As an application for therapy by growing such augmented reality, virtual space and sharing of data through the Internet and also inexpensive its availability have recently expanded the base. There are other benefits of Virtual Reality Therapy offering active interaction environments for cognitive experience which can provide appropriately adjusted environments for patients who are hard to overcome the real situation because of phobia. In addition to that it is safe and economical and patients' confidentiality is assured. Moreover, due to the principles of applying real-time navigation the Virtual Reality Therapy makes modification and supplementation easier and also it can reduce cybersickness because of the supply of Lenticular allowing people to see stereoscopy without eyeglasses, which makes sense of presence clearer. On top of that due to the development of interactive technologies, it is becoming close to sense of reality similar to real world by leading users to navigate by themselves and to operate objects in a virtual space. This paper will therefore examine, although it is of limited, characteristics of application of virtual reality technology based on A Human-Sensibility Ergonomics used for treatment for a disorder. this paper will analyse a range of its application and problems and it will suggest the future possibilities.

  • Objective : This empirical research is performed to recognize diagnostic concept, pattern identification, and clinical features of Hwa-byung. In other words, the aims of this research are to examine the differences of the diagnosis between Hwa-Byung and the other psychiatric disorders, and to find out pattern identification, and clinical characteristics of Hwa-Byung for prescriptions of this syndrome. Method : In the experiment, there were participated 30 patients who were met for our criterions according to HBDIS (Hwa-Byung Diagnostic interview Schedule). These patients were diagnosed as Axis1 according to criterions of DSM-IV with administering SCID-I. OMS-prime was utilized for finding out pattern identification of oriental medicine. Symptom Check List-90-Revision(SCL-90-R), Hemilton rating Scale for Depression(HRSD), Heart Rate Variability(HRV), and Digital Infrared Thermographic imaging(D.I.T.I.) were also utilized to discover clinical characteristics of Hwa-Byung Patients. Results : 1. Regarding Sex-ratio, male subjects were 3(10%), and female subjects are 27(90%). The age of subjects ranged from 22 year old to 75 $(51.87{\pm}11.04;\:Mean{\pm}SD)$ 2. In the results of diagnosis on the basis of DSM-IV, the 17(56.67%) patients were MOD (Major Depressive Disorder), the 5(16.67%) patients were USD (Undifferentiated Somatoform Disorder), the 4(13.33%) patients were Dysthymic Disorder, the 3(10%) patients were GAD (Generalized Anxiety Disorder), and the 1(3.33%) was Panic Disorder. Two of the patients who diagnosed as MOD were diagnosed as Panic Disorder too, and one of them was diagnosed as Pain Disorder too. 3. Regarding pattern identification, Hwa-Byung is positively correlated to deficiency of Heart(心). and then to stagnancy of Liver-Gall bladder. Hwa-Byung is correlated deficiency symptom-complex rather than excessiveness symptom-complex. That is also correlated positively to Pathological heat and fire. 4. In SCL90-R, the mean of PSDI was $(75.3{\pm}10.7;\:Mean{\pm}SD)$. The each mean of the other 11 factors was distributed between50-70. 5. The mean of HRSD was $(17.9{\pm}5.6;\:Mean{\pm}SD)$ in the entire subject's group. Then the group of MDD was $20.9{\pm}4.4$ and the group of USD was $12.0{\pm}4.8$ 6. In the results of HRV. the mean of TP is $972.4{\pm}1174(Mean{\pm}SD)$, this is lower than normal range 1000-200. The other factors were within normal range. Then, there were no significant differences between them (p<0.05). 7. The temperatures of each acupoint have significant differences between HNl(印堂) and PC6(內關), between CV17(顫中) and PC6(內關), between HN1(印堂) and CV8(神闕), between CV17(顫中) and CV8(神闕) in comparison with the average of body temperature in the use of D.I.T.I. (p<0.01) 8. In the analysis of correlation between SCL-90-R, HRSD, HRV. and D.I.T.I. there were no significant results. According to results that the correlation was analyzed with only the MDD group as subjects, there was negative correlation between RMSSD of HRV and HRSD, between LF of HRV and PDSIof SCL-90-R, and between LF/HF of HRV and ANX, PSY, and PDSI of SCL-90-R. Conclusion : In the observation of clinical features of 30 cases of Hwa-Byung patients by using diverse structured tests, there could make diverse diagnosis as depressive disorder, anxiety disorder, and Somatoform Disorder. Particularly. MDD was highly distributed. Considering oriental medicine's pattern identification of Hwa-Byung, this syndrome is related strongly to Heart, and there were demonstrated deficiency symptom-complex, and Pathological heat and fire. One of the limits of this study is lack of control subject's group, therefore, in the future study, it requires reexamination through a comparative research with these data to complete this study.

  • With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

  • Objectives : In the psychiatry, structured interview is very important tool to be used in epidemiological or psychopharmacological studies. However, investigators often find that the administration of comprehensive diagnostic interviews is time-consuming and expensive to be used in clinical or research settings. Considering these points, Sheehan and his colleagues developed MINI (Mini International Neuropsychiatric Interview) to meet the need for a brief, reliable, and valid structured diagnostic interview for psychiatric disorders. The MINI has been translated into many languages and used in many countries. Therefore, we translated the MINI into Korean and determined its validity in this study. Methods : Twohundred seventy patients and normal subjects participated in the validation of the MINI versus an expert's professional opinion. Schizophrenia and other psychotic disorders, mood disorders including major depressive disorder and bipolar disorder, anxiety disorders including panic and other phobic disorders, and alcohol dependence were included in this study. The validity was obtained by examination whether MINI based diagnoses were compatible with diagnoses by expert psychiatrists. Results : The range of Kappa values was 0.22 (somatoform disorder) to 0.93 (bipolar disorder - past). Overall agreement between MINI and expert's diagnoses were good. The Kappa values for anxiety disorders seemed to be higher than those for other disorders. Conclusion : The MINI Korean version has the good validity. It also has potential applications as a diagnostic tool for psychiatric disorders.

  • The authors studied anxiety, using Zung's self-rating anxiety scale(SAS), in the subjects of 127 male and 38 female patients with anxiety disorder. The authors investigated 165 patients in Yeungnam university hospital from January, 1987 to June, 1991. In order to analyze the data on anxiety scores Pearson's product moment coefficient correlation method and factor analysis were carried out by SPSS/PC+ program. The results were as follows : There was significant difference in the mean averages of total anxiety scores among patients with anxiety, disorder and male and female college freshmen: patients with anxiety disorder scored $42.40{\pm}7.74$, male students scored $32.91{\pm}5.70$, female students scored $34.48{\pm}6.00$. The anxiety scores relating to the items of body aches & pains, fatigue, anxiousness, panic, and urinary frequency were relatively high in patients with anxiety disorder. The anxiety scores on the items of restlessness, apprehension, dyspnea, sweating, and insomnia were relatively low in patients with anxiety disorder. Twenty-nine anxiety disorder group(17.5%) showed significantly high anxiety scores of 50 or over. The inter-rater reliability of Zung's self-rating anxiety scale was 0.71.

  • Objectives : This study analyzed psychological aftereffects and made comparisons between victims who were either sexually assaulted or molested using the Minnesota Multiphasic Personality Inventory-2(MMPI-2). Methods : The participants were adult women who visited the Busan Smile Center within 6 months following sexual assault. This study categorized the participants according to types of sexual violence and then identified their social demographic features and characteristics. Student's t-tests were carried out to compare the MMPI-2 results between the sexually assaulted group and sexually molested group. Chi-square tests were also conducted to compare between participants who scored above 65T. Results : Among the 55 participants, 32 were sexually assaulted; 23 were sexually molested. Significant differences between the two groups were found in the following scales: F, F(B), F(P), Pt, Sc, Ma, RC6 and PSYC. Moreover, the number of participants with higher scores in the Pa, Pt, Sc, RC6, and PSYC scales in the sexually assaulted group was significantly higher than in the sexually molested group. Conclusions : Both groups of victims may commonly suffer beyond the moderate level of depression and anxiety in the post-case term. In addition, the sexually assaulted group seems to suffer relatively more from panic and psychological pain than the sexually molested group does.

  • The floor field model is the micro pedestrian model based on a cellular automata for modeling pedestrian movement in the interior space using the static and dynamic floor field. It regards a form of pedestrian as square but the actual pedestrian's shape and size are similar to ellipsoid or rectangle. Because of this, we are difficult to give a rotation effect to pedestrians and there is a limit to reflect an impact of clogging and jamming. Also, this model is not able to reflect an impact of a posture and visibility effectively in the pedestrian movement. In this study, we suggest the improved pedestrian model incorporating the actual shape and size of pedestrian. The pedestrian's shape is defined not square but rectangle which is close to the actual body size of Korean. Also, we define the model which is able to represent the impact of clogging and jamming between pedestrians by adding the pedestrian's posture. We develop the simulator for testing the suggested model and study the difference between two models by comparing a number of effects. As a result, we could confirm solving the problem with dynamic value in the existed model and reflecting the panic effect in evacuation situation.
