Semantic role labeling (SRL) systems determine the semantic role labels of the arguments of predicates in natural language text. An SRL system usually needs to perform four tasks in sequence: Predicate Identification (PI), Predicate Classification (PC), Argument Identification (AI), and Argument Classification (AC). In this paper, we use the Korean Propbank to develop our Korean semantic role labeling system. We describe our Korean semantic role labeling system that uses sequence labeling with structured Support Vector Machine (SVM). The results of our experiments on the Korean Propbank dataset reveal that our method obtains a 97.13% F1 score on Predicate Identification and Classification (PIC), and a 76.96% F1 score on Argument Identification and Classification (AIC).

Satellite remote sensing approach can be actively used for forest monitoring. Especially, it is much meaningful to utilize Korea multi-purpose satellites, an independently operated satellite in Korea, for forest monitoring of Korea, Recently, several studies have been performed to exploit meaningful information from satellite remote sensed data via machine learning approaches. The forest information produced through machine learning approaches can be used to support the efficiency of traditional forest monitoring methods, such as in-situ survey or qualitative analysis of aerial image. The performance of machine learning approaches is greatly depending on the characteristics of study area and data. Thus, it is very important to survey the best model among the various machine learning models. In this study, the performance of deep neural network to classify artificial or natural forests was analyzed in Samcheok, Korea. As a result, the pixel accuracy was about 0.857. F1 scores for natural and artificial forests were about 0.917 and 0.433 respectively. The F1 score of artificial forest was low. However, we can find that the artificial and natural forest classification performance improvement of about 0.06 and 0.10 in F1 scores, compared to the results from single layered sigmoid artificial neural network. Based on these results, it is necessary to find a more appropriate model for the forest type classification by applying additional models based on a convolutional neural network.

The purpose of this study was to identify the correlation between the intention of pregnancy and the child rearing attitudes of mothers with infants. The data was collected from 138 mothers by means of an interview and questionnaire in a period from April 1 to April 30, 1997, when they came to have their infants vaccinated at one hospital and one health care center. The collected data was analyzed by means of the SPSS Program using percentage, means and standard deviation in each area and the ANOVA and Pearson Correlation Coefficient. The results of this study were as follows : 1. It showed that the mother's degree of intention of pregnancy was 3.90(±1.49) among the possible score of 0∼5 and the score of child rearing attitudes was 70.1 among the possible score of 20∼100. The mom score of the items was 3.50(±.36) among the possible score of 0∼5. 2. There was a significant relation between the intention of pregnancy and child rearing attitudes. It was mildly positive but was significant (r=.21, p＜0.05). 3. There was a significant relation between the period from marriage to the time of pregnancy and the intention or pregnancy(F=.57, p<0.05). Also, it was found out that the group of mothers who became pregnant later than 12 months after marriage wanted after pregnancy more than the group of women who were pregnant within 12 months after marriage(F=11.30, p<0.01). 4. There was a significant relation between the period from marriage to the time of pregnancy and child rearing attitudes(F=4.14, p<0.05), It showed that the child rearing attitudes of the group of women who became pregnant later than 12 months after marriage was positive(F=11.42, p<0.01). Also, in case that the both the husband and wife decided on the pregnancy, the child rearing attitudes were more positive (F=7.15, p< 0.05). In conclusion, when the intention of pregnancy was stronger, the subjects' child rearing attitudes were more positive. Also when both the husband and wife decided on the pregnancy, the attitudes were more positive. So it seems that both husband and wife should discuss and agree upon pregnancy, having a sufficient period during which both the spouses prepare for the intention of pregnancy. Additionally, it is suggested that when the husband and wife are doing family planning, it would be beneficial to use a program of 'Woman's Intention on Pregnancy' during this process.

The purpose of this study was to clarify the level of knowledge and the attitude about AIDS. according to high school students demographics. and the AIDS education effects in a week or 6 months. The data were surveyed from 74 bounding for university high school students and 98 vocational high school students from two counties in Chonnam. The data were collected from November 5. 1999 to May 24. 2000. using a 50-item Questionnaire. and analyzed by SPSS PC+ program for t-test. ANOVA, Repeated measure ANOVA, Duncan test. $x^2-test$ and pearson correlation coefficients. The result of study summarized as follows : 1. The knowledge score for AIDS was significantly higher in the group bounding for university. in the second grade group and the group who have drunken experience. The positive attitude score for AIDS was significantly higher in the group who have smoked experience. 2. After 1 week of AIDS education. the knowledge score for AIDS(15.02 points) was significantly higher than the one before the education(10.85 points) but after 6 months of AIDS education. the knowledge score for AIDS(12.30 points) was significantly lower than in a week(F=55.49. p=.000). 3. After 1 week of AIDS education. the positive attitude score for AIDS(3.54 points) was significantly higher than the one before the education(3.35 points) and after 6 months of AIDS education. the positive attitude score for AIDS was same the one in a week(F=7.85. p=.000). 4. We could find the significant correlation between the knowledge and the attitude for AIDS just only in a week(r=.249. p=.001). In conclusion. the knowledge score for AIDS had increased in a week of education on AIDS but it had decreased as time goes by since education. The increased positive attitude for AIDS in a week has maintained the same as time goes by since education. Therefore. It should be needed re-education on AIDS to students at proper time in order to get the aim of AIDS education. We have to develop variety education methods for educational effects. It should be included comprehensive social aspect such as a question of personal rights to increase the positive attitude for AIDS.

The purpose of this study is to provide the basic data to improve the QOL in patients suffering from female cancers. Subjects of this study were consisted 255 persons who admitted or visited three university hospitals. The instruments used for this study included "the Quality Of Life Scale(QOL)" developed by National Conference on Cancer Nursing and successively amended by Kwon(1990), "Anger in" developed by Spielberger(1988) and successively amended by Chon(1997). The collected data were analyzed using a SPSS 11.0 for PC. To find out significant factors of Anger in & QOL in patients with Female Cancer patients, Frequency, Percentage, t-test, ANOVA, Scheffe-test, Pearson's correlation coefficients were conducted. The main findings : Anger in score was a little low & QOL score was middle. Several characteristics of the subjects were identified to differenti ate the "Anger in" and "QOL". Age status(F=2.64, p=0.05), education status(F=2.73, p=0.04), Health insurance(t=2.27, p=0.00) and cancer insurance status(t=2.97, p=0.00) was significant factors of the "Anger in". Education status(F=2.64 p=0.05), Occupation status (t=2.90, p=0.00), Monthly income (F=3.23 p=0.01), Stage of disease(F=9.23 p=0.00), Perceived health status(F=73.61 p=0.00), Perceived fatigue status(F=11.26 p=0.00) was significant factors of the "QOL". In conclusion, Anger in score was a little low & QOL sore was moderate. The degree of Anger in and quality of life were significantly negative correlated. Therefore, It is needed strategies for intervention of 'Anger in' to improve the QOL in female cancer patients. The significant characteristics of related to "anger in" & QOL should consider in sociopsychogical nursing intervention.

The purposes of this study were to investigate stress responses of senior high school students(examines) preparing for college entrance examination and to identify the relationship between stress responses and self-esteem. The subjects of this study were 261 senior high school students from three high schools located in three different Gu Seoul Korea. Data were collected from 19th to 27th march, 1998. Stress responses were measured by SOS (symptoms of stress) inventory and self- esteem was measured by Rosenberg's self-esteem scale. The data were analyzed with descriptive statistics, t-test, ANOVA and Pearson's correlation coefficient. The results were as follows : 1. The mean SOS score of subjects was 1.22 and that showed statistically significant according to gender difference (t=-6.00, P<0.0001) and father's occupations (F=3.10, P=0.006). 2. The mean self-esteem score was 2.77 and that showed statistically significant difference according to economic status(F=3.96, P=0.02) and father's occupations (F=2.71, P=0.01). 3. There was significant negative correlation between the mean SOS score and the mean self-esteem score(r=-0.31, P=0.0001). In conclusion, the examines had very high physiological and psychological stress responses and especially female showed higher stress responses than male. For this reason, school nurses are recommended (1)to develop appropriate stress management technique, (2) to provide more intensive care for health of female examines Nursing intervention should be developed for enhancing self-esteem of examines because self-esteem is negatively correlated with SOS.
