This study estimates the VSL(value of a statistical life) as well as the WTP(willingness to pay) for mortality risk reduction using sample selection model with data on liver cancer examination which is associated with little possibility of multi-purpose(i.e. joint production) in averting behavior. The marginal benefits of mortality risk reduction are estimated by applying for household production function model with medical expense and the time required for medical examination of liver cancer. Individuals are more likely to take liver cancer test if they are male, older, higher educated, those with spouse, smoker, more income of household, and more anxious about their health. The costs of liver cancer examination are statistically significantly affected with expected signs by size of mortality risk reduction, sex, period of eduction, those with spouse, and household income. The marginal effect of mortality risk reduction owing to taking liver cancer examination is estimated at 321,097 won. The costs of liver cancer examination are increased by 905 won with more one year of education period and by 1,743 won with more one million won in household income. On liver cancer examination, male spends more 12,310 won than female and those with spouse pay more 7,969 won than those without spouse. Therefore the VSL from mortality risk reduction due to liver cancer examination is 321.10 million won at mean size of mortality risk reduction and mean cost of liver cancer examination. The results of sensitivity tests on costs and effects of liver cancer test shows that the VSLs are estimated in a range from 160.55 million won to 642.19 million won.

Animation films form a substantial part of pop culture and depict the sociocultural changes and values of the time in which they are made through visual expression of story and characters. In the process of appreciating animation films and accepting the characters, the audience learns the gender role behaviors that appear in the works as socially acceptable representations of men and women. This study illustrates whether the expression of gender role and behaviors of characters from animation films have changed over time or not by analyzing the costume and gestures of the female protagonists in 'Mulan', 'Tangled', 'Moana', and 'Frozen 2'. These films are considered to reflect the modern female identity on their story and characters. The study confirms that the stereotypical gestures and behaviors of women are still used today to portray the female protagonists in the animation films contrary to the story composition and various aspects of characters which escaped the formal stereotype. It is important for children and adolescents, the main consumers of animation, to learn and know how to consume media properly. Thus, this study seeks to illuminate the importance of research on animation literacy eduction for children and adolescents by examining the visual expressions and their implications in various animation films.

Reaction kinetics for the solid-state reaction of $\alpha-Al_2O_3$ with amorphous $TiO_2$ to produce $Al_2TiO_5$ (Tialite) was studied in the temperature range of $1200~1300^{\circ}C$. Rate of kinetic reaction were determined by using $TiO_2$-coated $Al_2O_3$ compact containing 50 mol% $TiO_2$ and heating the reactant mixtures in MgO at definite temperature for various times. Amount of products and unreacted reactants were determined by X-ray diffractometry. Data from the volume fraction and ratio of peak intensities of $\beta-Al_2TiO_5$ indicated that the reaction of $\alpha-Al_2O_3$ with $TiO_2$ to form pseudobrookite starts between 1280 and $1300^{\circ}C$. The activation energy for solid-state reaction was determined by using the Arrhenius equation ; The activation energy was 622.4 kJ/mol.

This study began with the fact that the relationship between eductional environments and housing price needs to be understood in the context of the structuring of socio-spatial disparity. In other words, this paper focuses on the fact that the eduction with public features and functions plays a role of housing price determination and the rising price is privatized only to cause socio-spatial inequality. The study first examines how the education factors determine the housing price and cause increasing social inequality in Seoul at the macro level. It also carried out more detailed quantitative analysis on the relationship between educational environment factors and housing price with the case study of Yangcheon-gu, Seoul. This study found out that the close relationship between educational environment, housing price and social disparity at various spatial scales. It also figured out the the educational environment factors play an important role of housing price determination as much as material features per se. This means that the relationship between education, housing price and inequality needs to be dealt with not just socially but also in spatial perspective. In addition, the housing price determination is not just technical research but an social science issue in the context of rising socio-spatial disparity. This study is of only significance as a starting point of promising related researches in the future and much more efforts will be needed.

This study was intended to investigate recognition of the general public on water pollution and nonpoint pollution, and to promote participation of the common people in prevention and management of nonpoint pollution by investigating the necessity and participation in the education for reducing the nonpoint pollution. To this end, this study conducted questionnaire on 1,000 male and female adults over 20 years of age nationwide who are registered in Onpanel. The questionnaire was comprised of recognition on water pollution, preventive activity for nonpoint pollution, countermeasures for preventing nonpoint pollution, necessity of national education for reducing the nonpoint pollution, recognition of promotion and campaign participation, and revitalization of organization for reducing the nonpoint pollution. As a result of the questionnaire investigation, interest in water pollution of respondents was high, and specially, interest in the nonpoint pollution was higher when age, academic level, and income were higher that effectiveness of promotion and education on the source of nonpoint pollution is expected to be increased. Respondents recognized the effect of education on reducing the nonpoint pollution positively when they had higher interest, information, education and experience related to the reduction activity of nonpoint pollution. Therefore, formation of sympathy of the public is positively necessary for the nonpoint pollution management, and provision of civil activity program that increases information on the nonpoint pollution, education, and participation in reduction activity and easy promotion with high information communicability should be conducted continuously.

The purpose of this study was to assess the performance of the role and function of some industrial nurses and to characterize the factors affecting the performance of their activities. Thus the results could be used to suggest the direction in the performance of industrials nurses' activities effectively. During a period from January 10 to March 31, 1994, the data were collected from 87 industrial nurses, who were working as health managers in the plants, in Ulsan city and the vicinity in Kyungnam province, using a structured questionnaire. The results were as follows : 1. The general characteristics of industrial nurses in this study were 82.8% being 30 years old or less, 60.9%, being not married, and 93.1% having eduction levels above junior college. 2. With respect to general work conditions, 94.3% were working in a separate room provided for health care division, 40.2% working under the safety and health department, and 98.9% working as common-level staffs. And 60.9% were working less than 44 hours a week, 70.1% had work experiences less than 5 years, and 50.6% had annual incomes ranging 10 to 14 million wons. 3. As work conditions related to health care activities, 49.4% performed the activities not related to health care as always or occasionally, and 87.4% answered that occupational physicians were appointed in their plant and among them, however, only 6.9% worked on full-time basis and 52.8% perform little activities as occupational physicians. For a decision related to health care activity, 69.0% discussed the problems with the supervisors, and 19.5% made decisions by themselves. 4. As for attitude and perception to their activities as health managers, 66.7% moderately recognized the importance of health manager in the workplace, with 63.2% being satisfied their wages and treatment from the company, 57.5% being satisfied with their job positions and 51.7% having positive attitudes as being health managers. 5. The degree of performance at least in one of health related activities were very high in activities such as general medical care(100%), general health examination(98.0%) and specific health examination(100%), and relatively high in health education(72%), new employee health examination(60.9%), document handling(79.3%) and activity for work environment(70.1%). However, the performance rate was very low in preparing protective equipment (20.8%). 6. The levels of activities related to health care were significantly high when making decisions by themselves, when occupational physicians not being full-time, and when satisfying their job positions, and, on the other hand, significantly decreased as work hours increased. 7. In addition to some kinds of periodic education asked by all of the nurses, 89.7% wanted a specialized licensing system for industrial nurse, and 97.4% wanted to apply for the license test. As a conclusion, it is suggested that industrial nurses should be given more authority and placed in more self-controlled system to perform health care and other activities more efficiently, and the role and function of the occupational physician should be clearly distinguished from that of the industrial nurse as a health manager to avoid an unnecessary overlapping.
