To analyze how a horticultural therapy affects behavioral psychotic symptom and sociability of schizophrenic patients, a study was performed with 48 schizophrenic patients in a psychiatric institution in Daejeon, Korea. The horticultural therapy was conducted twice a week for a total of 29 sessions for seven months. Pre- and posttest assessment of behavioral psychotic symptom and sociability was done. Data from 48 patients who were not absent from the tests more than five times, and who performed every test item, were analyzed T-tests. Positive symptom(t=10.261, p=0.000), negative symptom(t=7.285, p=0.000) and general psychopathology(t=7.711, p=0.000) showed significant increase after application of horticultural program. Sociability of patients related to expression of their own opinions and respect to other persons through verbal(t=-4.64, p=0.000) and non-verbal(t=-6.43, p=0.000) showed significant increase after application of horticultural program. Substance of conversation(t=-5.58, p=0.000) was also increased significantly. Considering such healing effects of the horticultural therapy, it appeared to be a treatment technique that can improve the psychotic symptom and sociability of the schizophrenic patients.

The purpose of the study was to find out what the lavender aroma have an influence on changes in human brain electroencephalogram(EEG). We have conducted an experiment on 10 men and women in their twenties. After comparing digtal EEG(dEEG) with statistical EEG(SEEG) that put advantages of two methods together was applied to this experiment. The measurement was made through 19 channels using 32 channel digital EEG system, and it was made for 20 seconds with the sampling rate set to be 250 Hz. Then the part, which was not polluted by artifact, was adopted. After a clinician judged, the data without the artifact were gathered from the ones, which were measured 9 times in 19 channels, to construct statistical data base. Lavender fragrance had such an influence that δ wave was found in frontal lobe and temporal lobes of both side brains(FP1, FP2, T7, T8, F7, F8, C3, C4, Cz, F3, F4). This can be considered a characteristic of lavender, and more study on another effects of it should be continued. The influence of lavender aroma on human brain EEG will contribute to reducing the stress from which humans suffer.
