The purpose of this study was to verify the construct validity of the Sensory Profile for children with congenital cerebral palsy. Parents of 87 children(the ages of 3 to 10) with congenital cerebral palsy participated in this study. The data were analyzed through Winstep version 3.81 using the Rasch model to examine the uni-dimensionality of the fit of each item, the distribution of difficulty of each item, and the reliability and appropriateness of the rating scale. Based on a Rasch analysis, four out of the 87 children were considered to be inappropriate participants, and 15 item of the Sensory Profile was determined to be an inappropriate item. The items of high-level difficulty are needed as new items of the Korean Sensory Profile. The rating scale of three categories were appropriate than those of the five categories. The person and item separation reliability of three categories was above 0.90, which is a relatively excellent value. Finally, it will be need to verify of validity for Korean version of Sensory Profile, to develop new item of a high level of difficulty and convert into three point rating scale.

This study targeted college students to determine the moderating effect of immersion in the relationship among stress, satisfaction with life, and satisfaction with college life. To this end, the level of stress, satisfaction with life, satisfaction with college life, and immersion were measured in353 students attending S University. First of all, correlation analysis showed that stress had a negative correlation with immersion, satisfaction with life, and satisfaction with college life and immersion had a positive correlation with satisfaction with life and satisfaction with college life. Hierarchical regression analysis was conducted to determine the moderating effects of immersion in the relationship among stress, satisfaction with life, and satisfaction with college life. The results showed that immersion had a moderating effect on the relationship between stress and satisfaction with life, while immersion did not have a mitigating effect on the relationship between stress and satisfaction with college life. Based on these findings, this paper suggests raising the ability of immersion as a measure of intervention in handling the stress of college students and discusses the significance and limitations of this study.

This study was carried out to investigate the post stroke depression (PSD) occurrence in acute stroke patients and to identify the factors that influence PSD. The study subjects were 104 adults in their 20s or older who were scheduled to be discharged due to inpatient treatment for ischemic stroke in two hospitals. Data were collected using Post Stroke Depression Scale for PSD, Multidimensional Scale of Perceived Social Support for social support, National Institutes of Health Stroke Scale for stroke severity, and Modified Rankin Scale for disability. The average length of stay after stroke onset of the study subjects was 5.9±2.1 days, and 79.8% were within 7 days. Stroke severity score was an average of 2.4±2.5 out of 42 points, and disability score was an average of 1.6±1.1 out of 6 points. Among the subjects, 32.7% had mild or more severe depression after stroke. The subjects with no religion, severe disability, high stroke severity, and less family support had a higher likelihood of experiencing PSD. These results show that depression can appear in the early stages of stroke onset. Therefore, it is necessary to develop nursing guidelines for depression intervention after acute stroke, including continuous early assessment of depression from the acute phase of stroke and religion or family support.

The authors studied Psychoticism, using SCL-90, in the subjects of 3,893 male college students and 1,976 female college students of Yeung Nam University, collecting data during the periods from October to November, 1984. The results could be summarized as follows: 1. There was significant difference in the mean averages of total psychoticism scores between male and female students; male students scored $6.81{\pm}5.13$ female students scored $8.14{\pm}5.05$. 2. Eighty eight male students (2.4%) showed seriously high psychoticism scores of 20 or higher, while 63 female students (3.2%) showed the same scores. 3. In a comparison between male students in different school grades, freshmen showed the highest level of psychoticism scores, and as the grades of students became higher, the levels of psychoticism scores were lower. 4. Among the psychosocial factors, there were strong tendencies toward higher psychoticism scores in the students who were dissatisfied with their college, and hsd pessimistic views of self image in the past, present or future, in both groups. 5. The male students whose educational fees were paid by their parents, and whose spending money per month was under 10,000won, showed higher level of psychoticism scores. 6. The female students whose maturation locations were city, who were dissatisfied with their departments, who resided in dormitory of other residencies, and whose educational fees were paid by their brothers or sisters, showed higher level of psychoticism scores. 7. The items relating to 5(Feeling lonely with people) 9 (Never feeling close to another) 10 (Idea something with mind) in psychoticism and the item of depressed affect in SDS were significantly correlated over 0.40 of correlation coefficient.

This study was attempted to understand the relationship between the attitudes toward abortion, euthanasia, and the level of perception of good death among nursing college students and related factors. The data were collected by using structured questionnaires and the subjects were selected in C and G city. The research method was a descriptive research study, and the mean, standard deviation, frequency analysis, and Pearson's correlation coefficients were analyzed for the variables. The results of this study are as follows. The degree of support for the abortion opposition was 2.51±.56 (score range 1-4), and the opposition to abortion was superior to the approval..The perception of euthanasia was 3.06±.47 points (4 point scale), which was positively recognized at a higher level than the middle, and the good death perception was 2.97±.47 points (4 point scale), which was moderate. 97.1% of the respondents said that they had abortion decisions, and 5.7% of the university students experienced abortion. The attitude toward abortion showed negative correlation with the attitude toward euthanasia (r=-.374, p<.001), showing that the more supportive the anti-abortion, the more positive the attitude toward euthanasia. Therefore, it is necessary to educate the subjects to protect and respect the human rights of patients based on the dignity of life and humanistic thinking while providing nursing services.

This paper presents a hybrid face recognition method of both the first moment of image and the independent component analysis(ICA) of fixed point(FP) algorithm based on Newton method. First moment is a method for finding centroid of image, which is applied to exclude the needless backgrounds in the face recognitions by shifting to the centroid of face image. FP-ICA is also applied to find a set of independent basis images for the faces, which is a set of statistically independent facial features. The proposed method has been applied to the problem for recognizing the 48 face images(12 persons o 4 scenes) of 64*64 pixels. The 3 distances such as city-block, Euclidean, negative angle are used as measures when match the probe images to the nearest gallery images. The experimental results show that the proposed method has a superior recognition performances(speed, rate) than conventional FP-ICA without preprocessing. The city-block has been relatively achieved more an accurate similarity than Euclidean or negative angle.
