When women are removed with their matrix which is a emotionally significant organ of symbol in psychologically adapting themselves to mother and woman, that is threatened and injured with woman role decisively. This study tried to find the efficient nursing intervention method to maintain and promote their health, to cope with health problem, and to inquire into the loss experience of women with hysterectomy by using the phenomenological method. The analysis of the data was made through the phenomenological analytic method suggested by Giorgi. The result of the study was as follows : The factors which have influence on the loss experience of the subjects are an offer of information, support system, age, occupation, economic situation, family history, character, season, the existence of ovary and religion. The loss experience of matrix was expressed in lingual, reactions to the loss of function, sex, body change and husband, in behavioral behaviors in emotion and body. The loss of matrix of the subjects was relived by religion. perineorrhapy, exercise, reading, watching video and diet. The subjects each showed ways of reaction of fatalism, giving-up, coping on the loss experience of matrix. In conclusion, since we ascertained that the nursing in the process of recovery decide the quality of life. though women with hysterectomy undergo various loss experience and adapt to it in the end, it is necessary to give them enough information and educate husband, having on important effect on the loss experience, to be a good supporter, And technically skilled nurses of consultant are thought to be able to contrive better qualitative life of women with hysterectomy as an important bridge between the subjects and their required information, since the nurses have their well-formed position of relationship of confidence through continuous contact with patients and their family.

In this paper, we propose a digital transceiver that can overcome the problems which current analog transceivers have. For the proposed transceiver, we assumed a frequency resource that consists of discrete and narrow channels. We also assumed that person-to-group, group-to-group, as well as person-to-person, voice and data communications with moderate security should be devisedand the data rate is 1 Mbps with simultaneous voice and data. Frequency hewing spread spectrum (FH-SS) and differential 8-PSK (D8PSK) were adopted for security reasons and bandwidth constraints, and for the reduction of implementation complexity, respectively. For the carrier and the symbol timing recovery, the structure of the preamble was proposed based on the IEEE 802.11 FHSS frame format to improve detection probability. The computer simulation results and power budget analysis implies that the proposed system can be usedin simple wireless communications in place of such as analog walkie-talkies.

When women are removed with their matrix which is a emotionally significant organ of symbol in psychologically adapting themselves to mother and woman, that is threatened and injured with woman role decisively. The nursing for women with hysterectomy is limited to medical treatment and the nursing related to troubles in psychology, emotion they experience in general situation due to operations is hardly realized. New basis for nursing can be realized when we both have relation with lived human experience related th health and become to be a part of it. We need to catch their experience due to the loss of matrix to understand women with hysterectomy. The subjects of the study were nine patients who were admitted to a gynecological ward of a hospital in Seoul, suffering from vaginal bleeding, back pain, abdominal pain and so on and diagnosing as non-cancer. The data were collected from April to May 1997 by listening to the subjects' expression of their experience and by participant observation of the subjects' reactions. A tape-recorder was used under the permission of the subjects, to prevent the loss of spoken information. The result of the study was as follows : The data on burden content from the interview were categorized as psych-emotional, physical, personal interaction, financial burden and maternal role burden. The factors which have influence on the burden of the subjects are an offer of information, support system, age, occupation, economic situation, family history, character, season, the existence of ovary and religion. In conclusion, since we ascertained that the nursing in the process of recovery decide the quality of life, though women with hysterectomy undergo various burden experience and adapt to it in the end, it is necessary to give them enough information and educate husband, having on important effect on the burden experience, to be a good supporter. And technically skilled nurses of consultant are thought to be able to contrive better qualitative life of women with hysterectomy as an important bridge between the subjects and their required information, since the nurses have their well-formed position of relationship of confidence through continuous contact with patients and their family.

In this paper we implement computer simulation system of 4FSK signal MODEM using Quadrature detector and analyze overall tranceiver system. We follow the FLEX wireless paging system standards and construct premodulation filter and data frame. We propose an efficient open loop symbol timing recovery algorithm which takes advantage of 128 bit length preamble pattern and also propose a 32 bit UW pattern which Is based on the optimal UW detection method, and excellent aperiodic autocorrelation characteristic. The BER simulation in the fading channel as well as AWGN is performed with BCH coding and Interleaving to the Quadrature detector system and it is shown that a high coding fain occurs in the fading channel rather than AWGN channel.

This paper propose the VSS-FC-MMA algorithm that is possible to improve the equalization performance based on varying step size to the FC-MMA adaptive equalization algorithm in order to reducing the intersymbol interference effect occurred in the nonconstant modulus signal transmission, and improved performance were confirmed. The FC-MMA is possible to improve the convergence speed, and degrades the steady state performance based on the fixed step size and modified dispersion constant considering the level number of signal symbol for obtain the error signal in adaptive equalization compared to MMA. The proposed VSS-FC-MMA uses varying step size and current FC-MMA possible to improve the steady state equalization performance, it was confirmed by computer simulation. For this, the signal recovery capabilities and residual isi, MSE, SER were applied for performance comparison index in the same channel and signal to noise ratio. As a result of computer simulation, the proposed VSS-FC-MMA improve the risidual value in steady state and SER performance than the FC-MMA, but has 1.7 times slow convergence time by using varying step size.

This paper intends to suggest the positive, ecological vision of sustainability in Karen Hesse's Out of the Dust that Billie Jo Kelby recovers herself through her readjustment of interior consciousness and outer environment in her tragic situations caused by the Dust Bowl. In spite of her desires for happiness and affluence of home, she loses her mother and brother, and her musical talent as a pianist, and lies in self-abandonment. But she finally raises up herself with her courage and patience, reconciliating with the nature and ameliorating the community by taking care of the devastated landscapes. Hence it is appropriate to approach the loss-recovery process of nature and consciousness with ecological solutions, The Dust Bowl breaks down human mind and body, and eventually leads to the situations of despairs and death. Hesse proposes the primary solution that humans should reconstruct their interior consciousness and participate in recovering the nature because humans are inevitably linked with nature. In this novel, the nature takes a dynamic and active role as a catalyst, reconciling the self with other humans and settling with the conflicting situations in history and culture. This verse novel as an active, self-ordering, and corrective process gives the more intense ecological message. As Hesse defines the setting of Dirty Thirties as a channel of energy, she creates the utmost effects of ecological process that human and environment are part of a total situation, representing the transactional formulation, each conditioned by conditioning to the other. Therefore Billie Jo takes her part as an interpreter and actualizes herself, understanding the nature with metaphor and symbol. Eventually Billie Jo realizes that she should rebuild her environment not out of the dust but in the dust, accepting the reality of Dust Bowl.

Objectives: It is known that sedative hypnotics would make cross tolerance with alcohol and deteriorate quality of sleep in alcoholics. Light therapy is effective non-pharmacological intervention for sleep disturbance in circadian phase disorders, jet-lag, shift-work and age-related sleep disorders. Authors would investigate the effects of morning light therapy on sleep of patients with alcohol dependence during recovery state without withdrawal symptoms. Methods: 13 patients with alcohol dependence who have not any alcohol withdrawal symptom were recruited. Light therapy during 1 hour in the morning had been administered by 2500 Lux light box through serial 3 days. Sleep state of subjects were assessed by sleep log and the subjective satisfaction at sleep was by 100 mm visual analogue scale. Sleepiness, depressive mood, anxiety were evaluated by 100mm visual analogue scale at 8 AM, 2 PM and 8 PM. For assessment of performance ability that would be associated with sleepiness and vigilance, trail making test A, B and digit symbol substitution test were performed by two times on base line and 4th day. Univariate repeated-measures ANOVAs were performed for each measures except performance tests which were analysed by paired t-test. Results: Sleep latency and sleep efficiency were significantly improved with light therapy and satisfaction at sleep was. There was no significant difference in sleepiness at 2 PM with light therapy but sleepiness at 8 AM significantly decreased and at 8 PM increased. The time to complete Trail making test and digit symbol substitution test were significantly shortened at 4th day compared with baseline. Fatigue at 8 AM were not significantly changed with light therapy but at 2 PM and 8 PM significantly decreased. Depressive mood and anxiety were not significantly changed with light therapy. Conclusion: Although this study had some limitations, it showed that light therapy would be effective modality on sleep disturbance of patients with alcohol dependence who have recovered from alcohol withdrawal symptoms. It is proposed that short term light therapy could be used clinically for alcoholics with insomnia. In the future, long term controlled studies using more objective tools for sleep are required to further investigate the effect of light therapy in alcoholics.
