  • In this study, we measure and analyzed variation of EEG signal by anesthesiologist progress step. In an experiment, the EEG signal was acquired and analyzed as 5 steps(prior surgical operation, during induction, surgical operation, awakening, posterior surgical operation). As a result, we confirm the anesthesiologist progress phase, concluded the possibility of anesthesia depth because using SEF and MF, and Delta ratio confirmed that can presume operating patient's consciousness state.

  • According to a case of Supreme Court's Sentence No. 2009DA17417 (May 21, 2009), the Supreme Court judges that 'the right to life is the ultimate one of basic human rights stipulated in the Constitution, so it is required to very limitedly and conservatively determine whether to discontinue any medical practice on which patient's life depends directly.' In addition, the Supreme Court admits that 'only if a patient who comes to a fatal phase before death due to attack of any irreversible disease may execute his or her right of self-determination based on human respect and values and human right to pursue happiness, it is permissible to discontinue life-sustaining treatment for him or her, unless there is any special circumstance.' Furthermore, the Supreme Court finds that 'if a patient who is attacked by any irreversible disease informs medical personnel of his or her intention to agree on the refusal or discontinuance of life-sustaining treatment in advance of his or her potential irreversible loss of consciousness, it is justifiable that he or she already executes the right of self-determination according to prior medical instructions, unless there is any special circumstance where it is reasonably concluded that his or her physician is changed after prior medical instructions for him or her.' The Supreme Court also finds that 'if a patient remains at irreversible loss of consciousness without any prior medical instruction, he or she cannot express his or her intentions at all, so it is rational and complying with social norms to admit possibility of estimating his or her own intentions on withdrawal of life-sustaining treatment, provided that such a withdrawal of life-sustaining treatment meets his or her interests in view of his or her usual sense of values or beliefs and it is reasonably concluded that he or she could likely choose to discontinue life-sustaining treatment, even if he or she were given any chance to execute his or her right of self-determination.' This judgment is very significant in a sense that it suggests the reasonable orientation of solutions for issues posed concerning withdrawal of meaningless life-sustaining medical efforts. The issues concerning removal of medical instruments for meaningless life-sustaining treatment and discontinuance of such treatment in regard to medical treatment for terminal cases don't seem to be so much big deal when a patient has clear consciousness enough to express his or her intentions, but it counts that there is any issue regarding a patient who comes to irreversible loss of consciousness and cannot express his or her intentions. Therefore, it is required to develop an institutional instrument that allows relevant authority to estimate the scope of physician's medical duties for terminal patients as well as a patient's intentions to withdraw any meaningless treatment during his or her terminal phase involving loss of consciousness. However, Korean judicial authority has yet to clarify detailed cases where it is permissible to discontinue any life-sustaining treatment for a patient in accordance with his or her right of self-determination. In this context, it is inevitable and challenging to make better legislation to improve relevant systems concerning withdrawal of life-sustaining treatment. The State must assure the human basic rights for its citizens and needs to prepare a system to assure such basic rights through legislative efforts. In this sense, simply entrusting physician, patient or his or her family with any critical issue like the withdrawal of meaningless life-sustaining treatment, even without any reasonable standard established for such entrustment, means the neglect of official duties by the State. Nevertheless, this issue is not a matter that can be resolved simply by legislative efforts. In order for our society to accept judicial system for withdrawal of life-sustaining treatment, it is important to form a social consensus about this issue and also make proactive discussions on it from a variety of standpoints.

  • This work investigates the characteristics of brain interactions of experienced Zen-Buddhist practitioners by obtaining multichannel EEG (electroencephalogram) data. Brain interactions were compared among three phases-40-minute meditation (M), 5-minute Chakra-focusing practice (Z) and rest with closed eyes (R). The similarity index S, developed in nonlinear dynamical system theory, was employed to measure the degree of possibly asymmetric coupling. Meditators exhibited, overall, stronger interactions among multiple cortical areas in meditation stages M and Z than in the R state. This enhancement was greater in the M stage when the meditator was accompanied by a thought-free and fully consciousness state. In the high-frequency band (>13Hz), the interdependence was also higher in both meditation stages than at baseline rest. However, the interaction strength, especially in the posterior regions, was greatest in the Z stage, which involved internal attention. Few electrode pairs were observed with significant pair-wise asymmetry in the Z state. The similarity is a possible characteristic of dense reciprocal and strong mutual interactions between multiple cortical areas during meditation - especially in the Z state in the high-frequency band. These results demonstrate that profound Zen meditation induces various dynamic states in different phases of meditation, possibly reflected by nonlinear interdependence measure.

  • We intended to identify the health state of Oriental medical students and also to know how many things of health practice are in healthy group and non-healthy group classified by the THI average score, according to sasang constitution. We collected data with self-administered health questionnaires from 297 men and women, in 9 Korea oriental medical colleges. We diagnosed Sasang constitution using QSCC II and also estimated health degree using THI. Non-healthy group practiced much more health behaviors than healthy one, and there were significant difference in Taeeumin and Soeumin. Non-healthy group of Taeeumin, Soeumin and Soyangin all practiced much more constitutional health behaviors than healthy one, and Soeumin non-healthy and healthy one all practiced much less health behaviors than Taeeumin and Soyangin group. Non-healthy group practiced health behavior for health care and maintenance more than healthy-one, and health state was related with sasang constitution health care. Therefore, institutional and systematic environmental condition would be needed in practicing healthy behaviors for improving the quality of health, and especially developed health promotion programs according to Sasang constitution too.

  • This study aims to find out the relationship between purchase intention of fashion products and affecting factors. Measurement was not on the general Web environment but on the individual websites. It was modeled that the likeness of shopping malls affects purchase intention. Flow, which Csikszentmihalyi(1990) introduced as the state of optimal experience, was to affect purchase intention through the likeness of shopping malls. In addition, characteristics of fashion products were to affect purchase intention. A structural equation modeling was used for estimation. The result shows that the likeness of shopping malls affect purchase intention more than characteristics of fashion products. The difference from other studies is that the sign of Skills on Flow is negative. The effect of Flow on purchase intention is the largest and the next is the characteristics of the shopping malls. These results imply that internet shopping malls have to increase the likeness of shopping malls in addition to interests of the products. In addition, fashion consciousness was tested as a moderator by dividing the subjects into two groups of high and low fashion consciousness. The result shows that fashion consciousness works as a moderator for the variables affecting purchase intention.

  • Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.

  • The study aims present data collection on the current state of safety and safety consciousness in universities' laboratories to verify the relation between investigation factors and further draw implications. The first finding is that laboratories with high risk level do not have better safety management performance than those with lower risk level. Secondly, labs that experienced accidents has a higher level of control than those without any. Regarding to the university's acceptance of safety requirements, the group with a high level of risk awareness or accidents were concerned that their universities did not provide sufficient support in safety management. It means that safety is low on the list of priorities in Universities' overall agenda and individual labs are responsible of their own safety. Most of the causes of accidents in the labs are man-made than physical errors. It requires that continuous safety educations and measures through safe research activities are means to eliminate and reduce the individual's safety frigidity. Through the survey, it is known that current education's system and contents are too generalized to reflect the characteristics of each laboratory. Thus, it is difficult to recognize various risk situations and to actually prevent safety accidents. Therefore, it is necessary to shift to customized curriculum and system for various major fields.

  • Purpose: This study is a descriptive study to analyze the relationship between the cognitive function, body image and pain, and the influencing factors on the daily life performance of brain injured patients. Methods: The study subjects were 119 inpatients with brain injury who gave informed consent. The activities of daily living (ADLs), cognitive function, pain and body image were measured by Modified Barthel Index (K-MBI), K-MMSE (Mini-Mental State Examination), Visual Analog Scale (VAS), Semantic Differential Method (SDM), respectively. Results: ADLs was significantly associated with body image, cognitive function, and pain. Multiple regression analysis showed that paralysis, consciousness, cognitive function, and pain were significant factors influencing ADLs. Overall, approximately 48% of total variability in the ADLs could be explained by the 4 variables ($R^2=.477$, p<.001). Conclusion: To improve ADLs of brain injury patients, a deeper understanding of paralysis, consciousness, cognitive function, and pain of patients is required and active nursing invention should be conducted.

  • The Chinese Architect Wangshu, who won the Pritzker Architecture Prize at 2012, is the first and only winner in China. This study focused on the expression of his unique architectural ideas. Especially with a high interest in Chinese traditional calligraphy and landscape painting, Wangshu tried to use its traditional features to form his own architectural way. First this study looked at the features of calligraphy and landscape painting. Second this research studied the expression of Wangshu's architectural practice in calligraphy's way. Lastly this study furthered study of Wangshu's architecture combined with landscape paintings' features. The results state these following. 1) For calligraphy, he used the "modular composition" of Chinese characters to architectural composition, which included architectural form and materials. The "similarities" and "space creation" of calligraphy are respectively applied to architectural spatial details and site planning. 2) For landscape painting, Wangshu borrows its elements to compose his architecture with "gardening consciousness". The "view method" of paintings was used to his architectural pedestrian flows, and Wangshu also based on the "space creation" of landscape painting to do architectural space design with creating the similar atmosphere.
