This study aims to investigate the specific functions of the five spirits based on the characteristics of five phases. In Korean medicine, the mind is classified into five spirits and seven emotions. The spirits (hon, sin, ui, baek, ji) are a way of analyzing of people's mental structures, and they are affected by each other, influencing life activities both directly and indirectly. They are also related to the five viscera and come into their own functions through the characteristics of the five phases that are assigned to the viscera. Sin is the main agent of mental activity that is normal, correct, and perfect, and it directs the other four. Hon is activity that is exposed to the outside from mental and physical aspects such as planning, creative thinking, creating, judgment, speech, and emotional expression. Baek is internal activity, such as obtaining information, learning, seeing, hearing, smell, taste, and touch. Ui is meant to decide between new and already saved information based on comparative analysis. Ji is the activity of making the final decision and saving it in ui. Based on the above, we suppose that the five spirits' functions match the characteristics of the five phases.

Ostreae concha is natural products of sea that haves good function for anti-stress. WE observed the effect of Otreae concha, Yukkwooltang and yukwool-tang add Ostreae concha for catecholamine, GOT, GPT, LDH and TG after immobilization stress, Ostreae concha depressed the stress response. In immunohistochemical analysis, The area of withe pulp of the spleen decreased in the control groups as compared with control ones. At same time, more severe histological changes of spleen such as the decreased diameter of periarterial lymphoid sheath and splenic node were demonstrated in the rats challenged with emotional stress. But these changes were slightly recovered in rats pretreated with Sample I, Sample II and Sample III. Immunohistochemical analysis showed that the expression of the inflammation-related protein tended to increase. But a decline of these expression, especially TNF-${\alpha}$ by pretreated with Sample I, were observed in the red pulp of spleen of the experimental rats. These results suggest that ostreae concha may act as a therapeutic agent for stress disease through a regulation of stress-related hormones.

This study investigates the physical properties and manufacturing method of shape memory fabric for emotional garment made by polypropylene. For this purpose, polypropylene(PP) POY and SDY were texturized using low temperature and constant length heat treatment texturing technologies, respectively. The shape memory fabrics made using these texturized PP yarns were woven with two kinds of PET and PTT shape memory yarns on the air-jet loom and the various physical properties of four kinds of shape memory fabrics were measured and discussed. The tenacity and breaking strain of PP texturized yarns treated by low temperature and constant length heat treatment showed high weaving efficiency and the wet thermal shrinkage of PP textured yarns was shown less than 1.5%, dry thermal shrinkage was ranged between 3% and 5%, which means thermal stability compared to the PTT textured yarn with high thermal shrinkage, 5~8%. The shape memory characteristics of PP shape memory fabrics measured by Toray method showed five grade as same value as PTT shape memory fabric. The heat keeping property of the PP shape memory fabric showed 56% higher value than that of PTT shape memory fabric. The water repellency of PP shape memory fabric measured by spray method showed five grade as same value as PTT shape memory fabric treated with water repellent agent. Especially, shape memory properties of PP shape memory fabric measured by 3-D image and camera measurement methods showed similar characteristics to the PTT shape memory fabric.

As the field of robots is evolving to intelligent robots that can replace even humans' mental or emotional labor, 'robot ethics' needed in relationship between humans and robots is becoming a crucial issue these days. The purpose of this study is to consider the ethics of robots and humans that is essential in this post-human age. It will deal with the followings as the main contents. First, with the cases of developing ethics software intended to make robots practice ethics, the authors begin this research being conscious about the matter of whether robots can really judge what is right or wrong only with the ethics codes entered forcibly. Second, regarding robot ethics, we should consider unethicality that might arise from learning data internalizing human biasness and also reflect ethical differences between countries or between cultures, that is, ethical relativism. Third, robot ethics should not be just about ethics codes intended for robots but reflect the new concept of 'human ethics' that allows humans and robots to coevolve.

The newly developed field of media art is quickly making progress to include various and up-to-date forms of expression. Unlike in traditional art, the communication between the art and the viewer has become vastly important, in which the viewer is an active agent who participates and interacts with the artwork. These digital artworks can now be readily observed in everyday places and things, rather than being confined solely in the gallery space. By encouraging open interaction with the public, media art has become more accessible. Accordingly, this thesis examines the construction of a real-time multimedia clock piece using particle systems. Time has always been a significant theme in the realm of traditional art, which continues to be explored extensively in various forms of expression. In an attempt to express the continuity of time and the state of being value of existence based on technological skills, the thesis presents an artwork that uses the popular medium of a clock while also providing both usability and emotional satisfaction for the viewer's sensibility through interaction.

This study aimed to investigate subtypes, risk factors, symptoms and the interventions to inpatients with delirium. The data of 108 inpatients who had the diagnosis of delirium during their hospital stay were collected from Electronic Medical Record at a university hospital and were analyzed by SPSS for Windows V. 26.0 program. As a results, Patients had a high proportion of elderly, male, orthopedic, and with fractures or amputations. The subtypes of delirium were hyperactive (51.9%), hypoactive (6.5%), and mixed (41.7%). Among the risk factors, depression and use of psychotropic agent were more common in those with hypoactive delirium. Among delirium interventions, behavioral symptom management and aggressive behavioral intervention were mainly implemented for those with hyperactive or mixed types, and emotional support was mainly implemented for those with hypoactive or mixed types. The delirium related intervention was more likely given immediately when the patients showed aggressive behaviors. Therefore, intervention strategies and protocol development are required for early detection of delirium in inpatients.

This study investigates the effectiveness of virtual reality agents as foreign language instructors with focus on the impact of different native language backgrounds and instructional roles. The agents were first distinguished as native or non-native speakers treated as a between-subject factor, and then assigned roles as either teachers or salespersons considered within-subject factors. An immersive virtual environment was developed for this experiment, and a 2×2 mixed factorial design was carried out. In an experimental group of 72 university students, statistically significant interactions were found in learning satisfaction, memory, and recall between the native/non-native status of the agents and their roles. With regard to learning confidence and presence, however, no statistically significant differences were observed in both interaction effects and main effects. Contextual learning in a virtual environment was found to enhance learning effectiveness and satisfaction, with the nativeness and the role of agents influencing learners' memory; thus highlighting the effectiveness of using virtual reality agents in foreign language learning. This suggests that varied approaches can have positive cognitive and emotional impacts on learners, thereby providing valuable theoretical and empirical implications.

Propofol is an anesthetic agent that gained wide use because of its fast induction of anesthesia and rapid recovery post-anesthesia. However, previous studies have reported immediate neurodegeneration and long-term impairment in spatial learning and memory from repeated neonatal propofol administration in animals. Yet, none of those studies has explored the sex-specific long-term physical changes and behavioral alterations such as social (sociability and social preference), emotional (anxiety), and other cognitive functions (spatial working, recognition, and avoidance memory) after neonatal propofol treatment. Seven-day-old Wistar-Kyoto (WKY) rats underwent repeated daily intraperitoneal injections of propofol or normal saline for 7 days. Starting fourth week of age and onwards, rats were subjected to behavior tests including open-field, elevated-plus-maze, Y-maze, 3-chamber social interaction, novel-object-recognition, passive-avoidance, and rotarod. Rats were sacrificed at 9 weeks and hippocampal protein expressions were analyzed by Western blot. Results revealed long-term body weight gain alterations in the growing rats and sex-specific impairments in spatial (female) and recognition (male) learning and memory paradigms. A markedly decreased expression of hippocampal NMDA receptor GluN1 subunit in female- and increased expression of AMPA GluR1 subunit protein expression in male rats were also found. Other aspects of behaviors such as locomotor activity and coordination, anxiety, sociability, social preference and avoidance learning and memory were not generally affected. These results suggest that neonatal repeated propofol administration disrupts normal growth and some aspects of neurodevelopment in rats in a sex-specific manner.

The aim of this study is to find out how married women who had had an abortions experience a change through Family Constellation. The consequent changes will occur in the perception of an abortion experience and in the relation between married women themselves and their family. The participants in the study were 9 married women aged 40~60 who have experienced an abortion, and data collection was carried out over 3 periods which were before, right after and one month after the Family Constellation experience through individual in-depth interviews. The chief methodology of this study is based on the one by Colaizzi's phenomenological research, and by using the methodology to analyze the data 15 theme collections and 3 categories were deducted. According to the result of the analysis, the experience of abortion was having negative influence on the whole spectrum of the life of married women who experienced an abortion even though they did not consciously recall the relevant experiences. In the married women's Family Constellation, the agent visualizes the restrained relation which is hidden in unconsciousness and thereby offers an opportunity for married women to untie "knot". Moreover through this opportunity, married women are able to have new perception of their abortion experience and the relation between their family. Furthermore, not only will they be able to recover the relationship with their family, but also emotional stability.

Bed rest is recommended to prevent postlumbar puncture headaches(PLPHA), but the period of bed rest varies in the literature from 6 hours to 24 hours. In clinical practice the period of bed rest varies but nursing methods for adults and children have little difference. In Seoul National University Hospital, children have been given at least 6 hours bed rest after a lumbar puncture. Pediatric oncology patients require a lumbar puncture for an initial diagnosis, follow up treatment or administration of chemotherapeutic agent. But it is difficult for young children to lie supine or to refrain from their usual activities in any way, and unpleasant problems related to a shortage of beds often occurs during discharge or in an outpatient setting. The purpose of this study is to substantiate the preventive effect of PLPHA by the period of bed rest, to identify the other factors that influence PLPHA, and to use the nursing methods proper to children. The subjects were 65 children, ages 1-17, undergoing treatment in the children's cancer center at SNUCH during the period June 1, 1995, to Aug. 31, 1995. The team nurses asked questions about PLPHA of the parents and children in order to fill out a questionnaire. The data were evaluated by percent, t-test, Chi-square test and Mann-Whitney U test. Result; 1. There was no significant difference relating the bed rest time spent to the occurrence of postspinal headaches (t-test). 2. There was a significant risk of PLPHA in the children who were irritable before procedure and/or had experienced previous PLPHA(p<0.05, ${x^2}-test$). 3. The following factors were not found to be associated with increased risk of PLPHA: previous puncture experience, giving analgesics, the choice of puncturist, inpatient/outpatient status, gauge of needle, purpose, the amount of CSF removed, gender, diagnosis, the number of peripheral WBCs, previous lumbago experience after LP, position after bed rest, age, the number of aural puncture at the time. A longer period of bed rest is unlikely to be more effective to prevent PLPHA and seems impractical. A shorter period will save time and effort. Perhaps it will also allay some of the fears which surround LP. So 1 hour bed rest after LP is suggested and nursing methods for emotional support should be investigated to reduce PLPH.
