Korea needs proper and rational public policies on conservation and use of forest land and other natural resources because of the accelerating expansion of national land developments in recent years. Unfortunately, there is no systematic planning system to support the needs. Generally, forest land use planning needs suitability analysis based on efficient land classification system. The goal of this study was to classify a forest land using multivariate satistical methods. A case study was carried out in winter of 1983 on a mountainous area higher than 100m above sea level located at Mt. Kwanak in Anyang -city, Kyung-gi-do (province). The study area was 19.80 km$^2$wide and was divided into 1, 383 Operational Taxonomic Units (OTU's) by a 120m$\times$120m grid. Fourteen descriptors were identified and quantified for each OTU from existing national land data : elevation, slope, aspect, terrain form, geologic material, surface soil permeability, topsoil type, depth of the solum, soil acidity, forest cover type, stand size class, stand age class, stand density class, and simple forest soil capability class. For this study, a FORTRAN IV program was written for input and output map data, and the computer statistics packages, SPSS and BMD, were used to perform the multivariate statistical analysis. Fourteen variables were analyzed to investigate the characteristics of their fire quench distribution and to estimate the correlation coefficients among them. Principal component analysis was executed to find the dimensions of forest land characteristics, and factor scores were used for proper samples of OTU throughout the study area. In order to develop the classes of forest land classification based on 102 surrogates, cluster and discriminant analyses of principal descriptor variable matrix were undertaken. Results obtained through a series of multivariate statistical analyses were as follows ; 1) Principal component analysis was proved to be a useful tool for data selection and identification of principal descriptor variables which represented the characteristics of forest land and facilitated the selection of samples.

The purpose of this study was to investigate self-perception of health and body image, blood lipid profiles and nutrient intake of adolescents. The subjects were 686 adolescent boys (379 middle school students, 307 high school students) and 613 adolescent girls (272 middle school students, 341 high school students) in Incheon. This cross-sectional survey was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for triglyceride, total cholesterol and LDL- and HDL-cholesterol. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. Average age, height and weight of male middle school students were 13.8 years, 163.5cm, 56.0kg and those of male high school students were 16.5 years, 171.7cm, 64.3kg. In female, average age, height and weight of middle school students were 13.7 years, 157.1cm, 51.5kg and those of high school students were 16.6 years, 159.7cm, 56.8kg. Female middle school students perceived their health status significantly better compared to female high school students (p < 0.001). Female high school students perceived themselves significantly fatter compared to female middle school students (p < 0.05). Average TG level of female middle school students was significantly higher compared to female high school students (p < 0.01). Nutrient intakes of the male and female students except phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of male and female students were under the 65% of the Korean RDA. Therefore, proper nutrition education is required for Korean adolescents to encourage desirable food habits and maintain nutritional lipids status. (J Community Nutrition 5(1) : 3∼12, 2003)

The degree-linked programs for employees, operated by joint training centers in specialized universities that have implemented work-study integrated programs, are educational programs that require an annual government budget of around 80 billion KRW. However, the 70+ universities running these programs face issues such as a decline in academic achievement and an increase in dropout rates among students. In this paper, I conducted multiple regression analysis based on observed and measured information to examine whether the participating students in these programs are achieving an appropriate level of academic performance and to identify the factors that universities need to invest in to achieve that level. To do this, I hypothesized a causal relationship between the university's input factors and students' academic achievement, and used the SPSS program to analyze the statistical data, confirming the validity of the hypothesis. The collected data for the study were obtained through a survey developed using a Likert 4-point scale, which quantified the distribution of grades among students enrolled in IT-related departments offering the degree-linked programs for employees and the emotional contact efforts made by the universities to motivate them for academic success. Particularly, through the results of multiple regression analysis, it was confirmed that these input factors, unlike those for students in general education programs, require more personalized and frequent interactions.
