Currently. exchanges of industrial workers between countries are more active than ever. and the problem of AIDS in connection with the operation of preventive educational programs has reached a point where the issue cannot be limited to native people alone any more. Based on such judgement. this research has been carried out to provide basic study materials by grasping the latent factors representing the difference between countries in the levels of right knowledge. attitude and behavior with respect to AIDS maintained by workers who have grown in different social and cultural living background. During the period from Apr. 1. 1995 to Jun. 30. questionnaires. written both in Korean and English, were distributed to Korean and Malaysian employees working at certain Korean video manufacturers. and the results of replies. given by 80 workers who were analyzed through matched sampling· method where ages and sex matched by country. were used as the research materials. The gathered materials were analyzed through the SPSS package t-test. ANOVA. factor analysis and multiple stepwise regression methods. and the following results were obtained. 1. The 2 extracted latent factors could be named 'common. social' knowledge factor and 'in-depth. psychological' knowledge factor respectively. 2. The percentile points of 'external. social' knowledge factor. in the case of Korean workers. howed 90.0 at average. a figure 13.75 points higher than those of Malaysian workers. 76.25. On the other hand. the percentile points of the 'in-depth. psychological'knowledge factor showed 70.80 at average in the case of Korean workers. a figure 7.47 points lower than those of Malaysian workers. 78.33. Meanwhile. the difference in percentile points between the 2 latent factors was 8.54 at average. indicating that the points of 'in-depth. psychological' knowledge factor was lower than those of the 'external. social' knowledge factor. 3. As for Korean workers. the percentile points of the 'in-depth. psychological' knowledge factor showed higher points in office workers than in non-office workers. and such variables exhibited in the position of workers can explain the $7\%$ of the latent factor. The percentile points of the 'in-depth. psychological' knowledge factors. in the case of Malaysian workers. showed higher points in groups who had religion than in groups who did not. and higher points in groups who obtained information from newspapers than in groups who obtained from televisions or other sources; and with these 2 variables. $26\%$ of this latent factor can be explained. The results. of analysis described so far suggest that while Korean workers possessed general level of knowledge on AIDS. they had low level of practical knowledge as far as its depth is concerned. and that they had social prejudice on patients as well as on the AIDS infection route. In addition. because the overall knowledge level of Malaysian workers. is lower than that of Korean workers. it suggests that separate programs intended for Malaysian workers are required prior to executing integrated programs.

The content of this study is the points of nutritional diagnosis for the residents nutritional evaluation, the analysis of the related factors and the educational material with Nutrition Education-Index. Two hundreds housewives were examined during the period of Jan. 20 to Jan. 30 in 1989. 1. In terms of the housewives' age, those aged 30 to 39 were 32.5% which was the highest and educational level, graduation of primary school was 31.5% which was the highest. The housewives who had no job were 60.0% and those who participated in community activities were 56.5%. 2. In terms of the points of nutritional diagnosis, 50 to 74 points were 51.5% which was the highest and total average was $65.1{\pm}15.0$. 3. As for the points of nutritional knowledge, the average was 54.9 points, attitude was 77.4 points and eating practice was 70.8points. 4. The number of clinical symptoms of nutritional deficiency was 16.1 ones per person. 5. As for the relation which nutritional knowledge, attitude, eating practice exert on one another, nutritional knowledge has negative correlation with eating practice(-0.04) and attitude has some correlation with eating practice(0.17). 6. The variable having to do with the points of nutritional diagnosis showed the highest correlation coefficient(0.55) as the points of nutritional knowledge. 7 As for the variable having to do with the number of the symptoms of nutritional deficiency, the higher points of knowledge(-0.05) is, the higher the totai averse points of nutritional diagnisis(-0.09) is, negative correlation was appeared. 8. The result in which the variant having to do with the number of clinical symptoms of nutritional deficiency was analyzed by multiple regression analysis showed that the lack of time for preparing meals in non agricultural households made the greatest contribution (9% explained) and the households having vegetable garden made the second greatest contribution(3% explained).

Analyzing patterns in data points embedded in linear and non-linear feature spaces is considered as one of the common research problems among different research areas, for example: data mining, machine learning, pattern recognition, and multivariate analysis. In this paper, data points are heterogeneous sets of biosequences (composite data points). A composite data point is a set of ordinary data points (e.g., set of feature vectors). We theoretically extend the derivation of the largest generalized eigenvalue-based distance metric D_ij(γ₁) in any linear and non-linear feature spaces. We prove that D_ij(γ₁) is a metric under any linear and non-linear feature transformation function. We show the sufficiency and efficiency of using the decision rule $\bar{{\delta}}_{{\Xi}i}$(i.e., mean of D_ij(γ₁)) in classification of heterogeneous sets of biosequences compared with the decision rules min_𝚵iand median_𝚵i. We analyze the impact of linear and non-linear transformation functions on classifying/clustering collections of heterogeneous sets of biosequences. The impact of the length of a sequence in a heterogeneous sequence-set generated by simulation on the classification and clustering results in linear and non-linear feature spaces is empirically shown in this paper. We propose a new concept: the limiting dispersion map of the existing clusters in heterogeneous sets of biosequences embedded in linear and nonlinear feature spaces, which is based on the limiting distribution of nucleotide compositions estimated from real data sets. Finally, the empirical conclusions and the scientific evidences are deduced from the experiments to support the theoretical side stated in this paper.

Lineament density maps can be used for the quantitative evaluation of relationship between lineaments and groundwater occurrence. There are several kinds of lineament density maps including lineament length density, lineament cross-points density, and lineament counts density maps. This paper reports the usefulness of the representative elementary area (REA) concept for lineament analysis. This concept refers to the area size of the unit circle to calculate the lineament density factors distributed within the circle: length, counts and cross-points counts. The circle is a unit circle that calculates the sum of the lineament length, lineament counts and the number of cross-points within it. The REA is needed to obtain the best representative lineament density map prior to the analysis of relation between lineaments and groundwater well yield or other groundwater characteristics. A basic lineament map for the Yongsangang-Seomjingang watershed of Korea, drawn from aerial black-and-white photographs of 1/20, 000 scale was used for demonstrating the concept. From this study, the conclusions were as follows: (1) the REA concept can be efficiently applied to the lineament density analysis and mapping, (2) for whole Yongsangang-Seomjingang watershed which has 6, 502 lineaments with an average lineament length of 3.3 km, the lower limits of each REA used for drawing the three density maps were about 1.77 $\textrm{km}^2$ (r=750 m) for lineament length density, 7.07 $\textrm{km}^2$ (r=1, 500 m) for lineament counts density, and 4.91 $\textrm{km}^2$ (r=1, 250 m) for lineament cross-points density, respectively, (3) the lineament densities are inversely proportional to the size of REA, and the REA can be calculated with this inversely linear regression model, (4) if the average lineament density values for the whole study area are known, the most accurate density maps can be drawn using the REAs obtained from each linear regression model, and (5) but critical attention should be paid to draw lineament counts density and lineament cross-points density maps because.

This study was designed to investigate effects of maternal education using Brazelton Neonatal Behavioral Assessment Scale(the following will be marked as NBAS) on the mother-infant interaction and infant behavior. The subjects of this study consisted of 48 pairs of normal mother and infant, 24 pairs for intervention group and 24 pairs for control group. The subjects were recruited from two general hospitals, and an OBGY clinic located in J city. The data were collected from July 30, 2001 to October 6, 2001. Prior to investigation and data collection, following operational hypotheses were set up in order to compare the investigative data against these operational hypotheses(H). H1: Intervention group will higher mother-infant interaction score than control group. H2: Intervention group infants will higher overall performance in infant behavior test score than control group infants. The results of this study were summarized as follows: 1. The mother-infant interaction score was 59.79 points in intervention group and 53.91 points in control group. The mother-infant interaction score of intervention group showed significant difference than control group. Therefore, hypothesis 1 was supported. 2. The infant behavior score of intervention group was significantly higher than control group, but partially. Therefore, hypothesis 2 was partially supported. 1) The social interaction(orientation) score was 46.58 points in intervention group and 43.50 points in control group. The orientation score of intervention group showed significant difference than control group. 2) The state regulation score was 26.79 points in intervention group and 25.33 points in control group. The state regulation score of intervention group showed significant difference than control group. In conclusion, present work demonstrated that maternal education using NBAS is an effective intervention method for promotion of mother-infant interaction and of infant behavior development. Author believes that many inexperience young mother may find NBAS-based maternal education beneficial for their nursing babies, therefore NBAS-based intervention is recommended to be adopted routinely as an integral part of neonatal nursing strategies.

Objective: The aim of this retrospective study was to assess the midfacial soft tissue changes following maxillary expansion using micro-implant-supported maxillary skeletal expanders (MSEs) in young adults by cone-beam computerized tomography (CBCT) and to evaluate the correlations between hard and soft tissue changes after MSE usage. Methods: Twenty patients (mean age, 22.4 years; range, 17.6-27.1) with maxillary transverse deficiency treated with MSEs were selected. Mean expansion amount was 6.5 mm. CBCT images taken before and after expansion were superimposed to measure the changes in soft and hard tissue landmarks. Statistical analyses were performed using paired t-test and Pearson's correlation analysis on the basis of the normality of data. Results: Average lateral movement of the cheek points was 1.35 mm (right) and 1.08 mm (left), and that of the alar curvature points was 1.03 mm (right) and 1.02 mm (left). Average forward displacement of the cheek points was 0.59 mm (right) and 0.44 mm (left), and that of the alar curvature points was 0.61 mm (right) and 0.77 mm (left) (p < 0.05). Anterior nasal spine (ANS), posterior nasal spine (PNS), and alveolar bone width showed significant increments (p < 0.05). Changes in the cheek and alar curvature points on both sides significantly correlated with hard tissue changes (p < 0.05). Conclusions: Maxillary expansion using MSEs resulted in significant lateral and forward movements of the soft tissues of cheek and alar curvature points on both sides in young adults and correlated with the maxillary suture opening at the ANS and PNS.

The purpose of this study was to provide basic data and information for the improvement of school foodservice and efficient management of cooks by surveying the working conditions and the job satisfaction of cooks at schools located in Chungbuk province. The questionnaires of 311 cooks were available for this study. 26.3% of respondents worked at elementary schools, 34.2% of respondents worked at middle schools, and 39.5% of respondents worked at high schools. 72.3% of them were in their forties, 24.4% worked during five to seven years, and 63.0% had qualification certificates. Their job satisfaction was examined from ten dimensions. Respondents were not satisfied with the wage system and working environment which scored 2 points out of 5 points(not satisfied). They gave 1 point out of 5 points to the promotion dimension(not satisfied at all) while organizational committment area received relatively high points. The overall job satisfaction level was 3.06 points. The evaluation of the factors that made their job unsatisfactory were evaluated and the bonus system, treatment system and the wage system were 3.80 points, 3.69 points, and 3.62 points, respectively. In order to improve the job satisfaction of school foodservice employees, a change of the wage system and welfare system are needed.
