Cancer patients have been suffered from the instability of mind/body and unbalanced homeostasis because of cancer progression and medical treatment such as chemotherapy, It is very important that appropriated actions can be promptly taken by monitoring cancer patients' mental conditions. For this reason, it is crucial to develop a monitoring method which is convenient and not harmful to their body. Brain-computer-interface(BCI) system is introduced for the purpose in this paper. Prefrontal brain waves of cancer patients and control groups have been measured by a portable neurofeedback(NF) system based on self-regulation of the human electroencephalogram(EEG). The NF system consists of the portable EEG amplifier and a headband with dry electrodes placed on Fp1 and Fp2 sites. Patterns of the prefrontal brain waves taken by computer are correlated to brain quotients by EEG-analysis program. Basic rhythm quotient, attention quotient, emotional quotient, anti-stress quotient and correlation quotient of control group have shown high significant level compared with the cancer patients group. On the other hand, the EEG patterns analysis is shown its possibility to be an important methodology of monitoring cancer patients' condition.

To evaluate long-term metabolic response of free-living Korean subjects consuming local sources adequately or slightly below habitual intake. Subjects, six male medical students aged 23-25 years were free-living, but consumed diets in the metabolic unit. They were healthy as determined from medical laborarory tests. They belong to the Korean middle-class. Temperature of outdoor during study were ranged between -2 to $26^{\circ}C$, whereas the indoor were $18-22^{\circ}C$. Animal protein ranged between 25-30% of total calorie. The three meals and a vitamin supplement to meet recommendation were given daily. Three 50day periods following the design were used to test the protein-energy adequacy of the diet. Urinary nitrogen excretion was measured daily. Fecal samples were pooled for the last 5 days of each week. Nitrogen balance was computed using 5mg N/Kg skin and miscellaneous losses. Body weight was measured daily. The study was covered on 126 metabolic observations weekly. Body weight changes were relatively stable with the energy intake of 37-44Kca1/kg, and N-balances were also relatively stable, but it was influenced by physical and or mental stress somehow. It could be assumed that the mean protein and energy requirement were $190{\pm}10mg$ N/Kg with $41{\pm}2$ Kcal/kg, and the mean digestibility of protein was 81% on these subjects with the experimental conditions. The protein requirement, however, could be cut down somewhat with some limited increaing of energy intake under parameters of N-balance and maintaining body weight. It was also observed a tendency of the requirement were getting smaller with the increase of body size.

Emotional expression is universal and emotional state impacts important areas in our life. Until now, analyzing the acquired EEG signals under circumstances caused by invoked feelings and efforts to define their emotional state have been made mainly by psychologists based on the results. But, recently emotion-related information was released by research results that it is possible to identify mental activity through measuring and analyzing the brain EEG signals. So, this study has compared and analyzed emotional expressions of human by using brain waves. To get EEG difference for a particular emotion, we showed specific subject images to the people for changing emotions that peace, joy, sadness and stress, etc. After measured EEG signals were converged into frequence domain by FFT signal process, we have showed EEG changes in emotion as a result of the performance analyzing each respective power spectrum of delta, theta, alpha, beta and gamma waves.

Objectives : As a part of plan to develop evidence-based treatment guidelines for depression that is more suitable for Korean situation, we investigate the present status and client's requirements for non-pharmacological treatment of depression in Korean clinical situation. Methods : Subjects were patients with depression in 12 university hospitals which are located in metropolises in Korea. We analyzed the records from questionnaires about current clinical status and requirements for the non-pharmacological treatment of depression in Korea. Results : 50.8% of the subjects have experienced non-pharmacological treatments for their depression. The preference of non-pharmacological treatment method of depression is exercise/interesting activity, counseling by psychiatrists and psychotherapy, and the best effective treatment method is psychotherapy (Es=4.36). Actually, the mean consultation time by psychiatrist is $11.31{\pm}7.16$ min, and the appropriate consultation time for client's situation is $18.39{\pm}8.95$ min. During consultation, patients' satisfaction measurement for psychiatrist's explanation about pharmacological treatment is $64.17{\pm}27.11$, and satisfaction measurement for psychiatrist's counseling for their depression about personal problems, resent stress, interpersonal relationship is $61.66{\pm}26.63$. Conclusion : In Korea, many psychiatrists offered biologically oriented treatment to their patients with depression, and patients' satisfaction measurement about consultation by psychiatrists is low. Many patients wanted to combined pharmacological and non-pharmacological treatment for their depression, and aspired to information about complementary and self-help treatment methods. It is necessary to develop non-pharmacological treatment guideline for depression which reflect the clinical situation in Korea and meet Korean patients' need.

This study purposed to apply function form content, the three concepts that have been discussed by many philosophers since ancient times, to fashion design. Specific research goals are : first, to define fashion design based on the three concepts : and second, to examine how each of the three concepts function-oriented, form-oriented and content-oriented design have been expressed in women's fashion in the $20^{th} century. For these purposes. the author considered Morris' semiotics, which is the theoretical background of the three concepts, reviewed previous researches in design area, and applied the findings to fashion design. According to the result of applying the threefold structure of semiotics. which is the theoretical background of the three concepts, the pragmatic dimension of fashion design comprehends all functional rules related to the use of dress such as body motion and protection, health and safety. air flow and durability, and its syntactic dimension comprehend all the formal elements of visual design such as the structure, shape, line, color and material of dress. The semantic dimension of fashion design includes the symbolic meanings of dress expressed by emotion, sentiment and images. The three dimensions exist interdependently with one another. According to the result of considering the characteristics of the three concepts in the scope of women's fashion in the $20^{th} century. function-oriented design is characterized by practicality and simplicity, and has been expressed as the fashion of functionalism in the 1920s, that of minimalism in the 1960s, and the basic style from 1970s to 1980s, 1990s and the present. Form-oriented design has pursued aestheticism, putting stress upon form, and has been expressed with organic shapes imitating patterns found in nature in the 1950s and with optical art fashion in the 1960s. Content-oriented design attaches importance to transmission of delicate meanings related to the mental world of human beings, and is represented with symbolic forms. Such a characteristic has been expressed in fashion in the early 20th century influenced by surrealism and, with various types of design breaking established forms as well as metaphors and humors that characterize design in the late 20th century.

This research will mainly focus on security issues in a university campus and delve into the risk factors and its characteristics due to the extreme polarization growth, and ultimately conduct research on legislative issues regarding safety & security management. A university campus is a miniature of the society, concentrated with human resources, material resources and knowledge information resources. It is also a region in which various underlying risk factors threaten these resources. However, due to the insensibility of danger and carefree indolence, these risk factors have been ignoring, leaving university campus amidst a "dead zone." Currently, a systematic and synthetic measures not only for safety inside the laboratory but also for the new type of crimes such as cyber crimes and motiveless crime due to extreme polarization, stress, uneasiness about the future, increase of mental illnesses, and drug abuse are urgently required. Therefore, I would like to introduce a legislative program in a crisis management perspective that can prevent universities from danger and protect the resources which would ultimately create a new security system.

Objectives : Jeon-Jeung(癲證) is one of negative symptoms from schizophrenia in Western medecine, which causes flattening of affect, emotional bluntness, and avolition. Compared with positive symptoms of schizophrenia, there is no established treatments that have been proved to be effective for negative symptoms, and since negative symptoms are chronically processed, they finally lead to devastate the mental health. Since Jeon-Jeung(癲證) is usually in set in adolescent period and tends to become chronic through life time, it is important to start getting treatments in early stage by being distinguished from other diseases, such as anxiety disorder. A patient in this case was affective blunting, general weakness, and delusion when sixteen years old. However, he refused to get Western medicine treatment and wanted oriental medicine treatment. Methods : The patient in this case had been suffered from severe stress from his family since he was young and had kept having irregular and unhealthy eating habits. Therefore, he diagnosed stagnant qi transforming into fire(氣鬱化火), heart blood deficiency(心血虛), and spleen-stomach deficiency cold(脾胃虛寒) and since then he had received several treatments including herbal treatment, acupumcture treatment, supportive therapy, and family therapy. These treatments were successful and reduced the level of symptoms. After discharged from the hospital, he had continued receiving outpatient treatment with his family for 8 months and his progress had been still observed after the discharge. Results : The symptoms of patient had been almost reduced and eliminated after he received 29days of admission treatment and the patient got better and better and now lives a normal life 8 months outpatient treatment. Conclusions : This result suggests that our oriental medical treatments and family treatments was effective on schizophrenia.

Sleep is the most basic and essential physiological requirement for mental health, and sleep disorders pose potential risks of metabolic and neurodegenerative diseases. Tryptic hydrolysate of ${\alpha}_{S1}$-casein (${\alpha}_{S1}-CH$) has been shown to possess stress relieving and sleep promoting effects. However, the differential effects of ${\alpha}_{S1}-CH$ on electroencephalographic wave patterns and its effects on the protein levels of ${\gamma}$-aminobutyric acid A ($GABA_A$) receptor subtypes in hypothalamic neurons are not well understood. We found ${\alpha}_{S1}-CH$ (120, 240 mg/kg) increased sleep duration in mice and reduced sleep-wake cycle numbers in rats. While ${\alpha}_{S1}-CH$ (300 mg/kg) increased total sleeping time in rats, it significantly decreased wakefulness. In addition, electroencephalographic theta (${\theta}$) power densities were increased whereas alpha (${\alpha}$) power densities were decreased by ${\alpha}_{S1}-CH$ (300 mg/kg) during sleep-wake cycles. Furthermore, protein expressions of $GABA_A$ receptor ${\beta}_1$ subtypes were elevated in rat hypothalamus by ${\alpha}_{S1}-CH$. These results suggest ${\alpha}_{S1}-CH$, through $GABA_A$ receptor modulation, might be useful for treating sleep disorders.

In order to investigate industrial fatigue due to visual display terminal (VDT) work of banking operations the questionnaire survey for subjective symptoms of fatigue was carried out on 470 bank clerks who had been engaged in VDT work for various length of work hours. The questionnaires comprised three groups of 10 items each, representing dullness and sleepiness (level of cerebral activation), difficulty in concentration (level of motivation) and bodily projection of fatigue. The results were as follows : 1. Of the 30 items of questionnaires, the highest percentage was accounted for by 'eye strain' (51.5% ), followed by 'feel stiffness in the neck or the shoulders'(33.4%), 'feel a pain in the low back'(26.8%), 'whole body feels tired'(19.6%) and 'feel headache'(17.9%) in the order of sequence. 2. The average weighted score for the first group of questionnaire items (dullness and sleepiness) was the largest among three groups and was followed by 'the third cup (bodily projection of fatigue) and the second item group (difficulty in concentration) in the order of sequence, suggesting the heavier mental stress of VDT work in banking operations rather than physical burden. 3. In terms of the age and sex of workers, work duration and VDT work percentage, the difference in average weighted score was noted only between sex, the score of female being larger than that of male. 4. The complaint rates of subjective symptoms showed close associations with the subjective optimums of room temperature, ventilation, illumination and noise level. 5. The significant correlation was showed between age, work duration and item of 'whole body feels tired', between VDT work percentage and items of 'eye strain' and 'feel stiffness in the neck or shoulders' and between all items of subjective symptoms.

Purpose: The purpose of this study was to analyze trends in complementary and alternative therapy in nursing research in Korea. Method: The researchers examined academic theses and dissertations published from 1990 to 2002, and 151 articles were used for the analysis. Result: Nursing research on CAT increased rapidly from 1995 Articles with quantitative research designs made up 93.9% of the total and there were more experimental studies than non-experimental studies. Patients who had surgery, mental disorders, renal failure, hypertension, arthritis, dementia & cancer were the most frequently participants in studies on CAT. The type of CAT used in nursing research were mind-body therapy (65.8%), manual healing therapy (28.7%), phamacologic & biological therapy (3.7%), bioelectromagnetics (0.9%) and herbal therapy (0.9%). In 44 articles both psychological and physiological parameters were used as dependent variables. In 34 articles only physiological parameters were used and in 13 only psychological parameters. The most frequently used physiological parameters in CAT were pain, physiological function and vital signs, while the most used psychological parameters were anxiety, depression and stress. Conclusion: More studies about CAT are needed to extend the role and fields for professional nursing. There is a need to conduct qualitative studies in nursing about the experiences of patients who receive CAT and nurses who use CAT.
