This study aims to find out changes of marital status and average marital life expectancy in Korea according to educational attainment. The study produces Korean marriage life table to accomplish the goal of study by introducing Wolfbein-Wool style working life table. Specific data utilized in this study are collected from the Population & Housing Census 2005 and Death Census 2005. Educational attainment is divided into four categories to accommodate to this study: elementary school course and lower, middle school course, high school course, college course and higher. Marriage rate, divorce rate, widowhood rate and death rate according to educational attainment are used as basicdata to analyze marital life expectancy. The results of this study are as follows: 1. As subjects age is younger, the average marital life expectancy of the highly educated tends to be higher. The disparity of average marital life expectancy according to educational attainment is apt to become narrow as subjects age is older. However, the gap between people who graduated from middle school and high school in older age group does not distinctive. 2. Males marital life expectancy is higher than females controlling for their educational attainment. 3. Males live with their wife for most of their lives but females live alone more than 10 years in every single educational categories. Based on the above, this study concludes that the average marital life expectancy is differentiated among age and sex according to educational attainment. Marital rate tends to be higher as educational level is higher. Divorce rate is lower in the highlyeducated group as their age is younger but this is apt to reverse as age is older. Furthermore, bereavement rate shows division according to educational attainmentsince one tends to marry other who has similar level of education with him or her. Therefore, educational attainment acts as an significant factor in Korean average life expectancy.

The purpose of the present study was to clarify the sexual difference of the Heath-Carter somatotype related variables in boys and girls from 7 through 19 years of age. In the study design, the subjects and the methods were used by the cross-sectional investigation. The subjects participated in this study were 7 through 19 years of age who belonged to typical primary, junior, senior high school and college students, and about 250 males and 250 females in each group and both sexes. Therefore, the total subjects were 3,046 males and 2,984 females. All subjects of this study lived in Pusan metropolitan city, Korea. Somatotype was calculated by the Heath-Carter's anthropometric somatotype method, In this study, in attaiment rates of sum of 4 sites skinfold and endomorphy growth, girls were significantly higher than boys in all ages intervals except through 13 years of aged groups, respectively. In attainment rates of humerus and femur breadths growth, boys were significantly higher than girls in all ages interval except 13 through 15 years of aged groups, respectively. In attainment rate of arm circumference growth, boys were significantly higher than girls in all ages interval except 7 years of aged group. In attainment rate of calf circumference growth, boys were significantly higher than girls in all ages interal except 15years of aged group. In attainment rate of ectomorphy growth, boys were significantly higher than girls in all aged interal except 8 thorough 12 years of aged groups. This results suggests the urgent necessity of developing systematic and sperate progams to treat such sexual difference in boys and girls.

This study focused on application and examination of the goal attainment scale(GAS) to participants diagnosed as schizophrenia spectrum and other psychotic disorders. The participants were instructed to set their own goals and evaluate them using the GAS. Scores of each participant's GAS were later calculated to determine the level of goal attainment. A single group pre-post test design and linear mixed effects models were used to examine application and effectiveness of the GAS. The results found that the average GAS scores increased along with observations and the rate of the increase were statistically significant. In addition, this study indicated the importance of self-determined goal setting, goal attainment, and supports of the process. Practical implication and limitation of this study were also discussed.

While attainment rates for $SO_2$ and CO approached 100%, those for $PM_{10}$, $NO_2$, and $O_3$ have been low during the past decade. The attainment rates for 24-h $PM_{10}$ and 8-h $O_3$ have been only 1~3% and 5~12%, respectively, since the standards were strengthened in 2007. Variations in the 99th percentiles of 24-h $PM_{10}$, 8-h $O_3$, and 24-h $NO_2$, which are used as criteria for determining exceedance of standards, were examined by region. Because the analysis was based on short-term high-concentrations, the effects of Asian dust were observed for $PM_{10}$. Accordingly, it is necessary to specify whether exceptional events such as Asian dust will be included or not in determining the exceedances of standards. While variations in $NO_2$ were not large, there was an increasing trend in $O_3$. In the Yeongnam region, the increasing rate of $O_3$ concentrations was small although the decreasing rate of $NO_2$ was the greatest. In the Gangwon region, $NO_2$ concentrations were almost unchanged, but $O_3$ concentrations experienced a significant increase. Regional management strategies targeting short-term high concentrations of criteria pollutants analogous to the Special Act for the greater Seoul area will aid in improving attainment rates.

This study determined tact process paths by separating the finish works according to the properties of work areas and work relations in order to apply the tact schedule management to the finish works. In addition, by suggesting preparing and sharing the workflow charts, the experiments can be shared between the executors and any possible frictions between the specialist works can be identified in advance. In addition, any errors on the plan can be reviewed and modified through the measurement stage of tact plan attainment rate. The process of tact schedule management is improved with such tools and methods and the efficiency of the process through the application of cases was verified.

This study investigates how dramatic increase of university and college graduates affects labor market outcomes. Using a series of seven repeated cross sections of the Vietnam Household Living Standards Surveys, this paper analyzed the changes in the rate of returns to higher education attainment along with the increased supply of university and college graduates due to the higher education expansion throughout the 2002-2014 period. The study utilized a ratio of number of university and college students to the number of upper-secondary pupils within each province as an instrumental variable to calculate the effects of higher education expansion on the labor wage. The study found that, with the basic equations, the coefficients for higher education attainment are statistically significant and have positive values for the whole period. Our instrumental variables were found to be valid. For instrumental variable estimation, the return to higher education in IV earning equations was quite high. The findings of this study suggested that the expansion of the higher education system in Vietnam during 2002-2014 had positive effects on wages for those who increased their education attainment due to the reforms and there was a declining trend of the returns to higher education toward the end of the period.

Effect of ethanol on the absorption rate, blood level and bioavailability of sulfamethazine (SM) in rats was determined. Absorption rate of SM was determined both by the in vitro and in situ experiment. In vitro, absorption rate of SM in rat small intestine was increased by 0.3, 1.0 and 3.0% ethanol. In situ, absorption rate of SM was increased by 0.3 and 1.0% ethanol but not by 3.0% ethanol. After oral administration, blood level of SM was elevated and relative bioavailability was significantly increased to 114.8% at the dose of 0.6g/kg ethanol but not significantly at the dose of 3.0g/kg ethanol. The time for attainment of peak blood level was changed from 2.5 to 1.5hr. Ethanol enhanced absorption rate constant of SM significantly and reduced elimination rate constant of SM administered orally at the dose of 0.6g/kg ethanol.

Purpose: This study targeted female university students in their 20s and created an antioxidant improvement program with a health contract, one of the behavioral modification therapies, based on King's (1981) 'goal attainment theory.' The aim of this study is to investigate the effects of physiological indicators, eating habits, dietary attitudes, and health behaviors by conducting a walking exercise and anti-oxidation diet program with reinforcement therapy. Methods: This study had a nonequivalent control group pretestposttest design. There were a total of 50 participants, with 25 participants in the experimental group and 25 participants in the control group and the study period was 10 weeks. The antioxidant improvement program consisted of walking and antioxidant diet education with health contracts. Data analysis was statistically processed using the SPSS/WIN 24.0 program. Results: The program showed a high achievement rate by providing continuous motivation and positive reinforcement during the program, and it affected the eating habits, dietary attitudes, and health behavior. Besides, physiological variables, such as antioxidant indices and body composition showed positive changes. Conclusion: This study, based on the goal attainment theory, confirmed that antioxidant improvement program is an effective nursing intervention for continuous health promotion through interaction and exchange between healthy participants and researchers.

Formation of protective iron carbonate films in $CO_2$ corrosion can reduce corrosion rate substantially and the effects have been incorporated in various prediction models. The $CO_2$ corrosion with the presence of free acetic acid is known to increase corrosion rate below scaling temperature. The possible interaction between the formation of iron acetate and iron carbonate films can affect the protectiveness of the film. The study is done using 3% NaCl solution under stagnant $CO_2$ -saturated condition at the scaling temperatures at various pH values and HAC concentrations. The result show that the presence of HAc does not affect the formation of protective iron carbonate film but delays the attainment of protective iron carbonate due to a possibility of solubilising of ferrous ions and thinning of the films.

This research explores the effect of Korean women's human capital on their employments. The first research question is which Korean women's human capital increase the rate of women's employment. And then the second research question is which Korean women's human capital affect the kind of women's job. In general, women's representative human capital indicates the educational attainment, the training of job skill, the certificate of job, and the their health. Human capital theoriests insist that individual's human capital determines the participation into the labor market, the type of job and wage. But in Korea it is well known that highly educated women's rate of employment is very low. The method of this research is logit analysis and regression analysis, using the cross-sectional data. We find in this research that women's human capital does not have a positive effect on women's employment rate. The longer women's schooling period is, the less women's participation rates into the labor market are. Women's training of job skill, certificate of job and health does not also have a statistical significance on their employment rate. Besides women's human capital does not affect the kind of job. So human capital theory is very limited explanation on Korean women's economic activities.
