The primary objective of this study was to classify different family values and to examine how university students' perceptions of childbirth differ according to the types of family values. The sample for this study consisted of 601 university students living in the cities of Seoul, Incheon, and the Gyeonggi province. The data were collected using structured questionnaires distributed through an online survey. Descriptive statistics including frequencies, percentages, means and standard deviation and cluster analysis, One-Way ANOVA and $X^2$ test are applied to analyze the data. The major results of this study are as follows: 1. The values of the university students regarding marriage, children, and familism were used as parameters to categorize the different types of family values on the cluster analysis. The results of the cluster analysis showed that the university students' family values could be classified into three types; "family-centered values", "individual-centered values", and "familism children-centered value". 2. The family values of the university students differed according to each student's gender, age, religion, socioeconomic status, gender-role attitude, and relationships with his or her father and or mother. 3. On average, the number of children that the students would like to have in the future is higher than the number of children that they actually plan to have. 4. The students' perceptions of family planning and low birthrate circumstances differed according to their family values. The university students categorized as having "family-centered values" planned to have the highest number of children in the future and thought that the low birthrate was a very serious issue, whereas the students with "individual-centered values" planned to have the lowest the number of children in the future. 5. To conclude the study, recommendations were made for the government to improve the low birthrate and for facilitate further research regarding this issue.

Statement of problem. One of the common problems of dental implant prosthesis is the loosening of the screw that connects each component, and this problem is more common in single implant-supported prostheses with external connection, and in molars. Purpose. The purposes of this study were: (1) to compare the initial abutment screw detorque values of the six different implant-abutment interface designs, (2) to compare the detorque values of the six different implant-abutment interface designs after cyclic loading, (3) to compare the detorque values of regular and wide diameter implants and (4) to compare the initial detorque values with the detorque values after cyclic loading. Material and methods. Six different implant-abutment connection systems were used. The cement retained abutment and titanium screw of each system were assembled and tightened to 32Ncm with digital torque gauge. After 10 minutes, initial detorque values were measured. The custom titanium crown were cemented temporarily and a cyclic sine curve load(20 to 320N, 14Hz) was applied. The detorque values were measured after cyclic loading of one million times by loading machine. One-way ANOVA test, scheffe’s test and Mann-Whitney U test were used. Results. The results were as follows : 1. The initial detorque values of six different implant-abutment connections were not significantly different(p>0.05). 2. The detorque values after one million dynamic cyclic loading were significantly different (p<0.05). 3. The SS-II regular and wide implant both recorded the higher detorque values than other groups after cyclic loading(p<0.05). 4. Of the wide implants, the initial detorque values of Avana Self Tapping Implant, MIS and Tapered Screw Vent, and the detorque values of MIS implant after cyclic loading were higher than their regular counterparts(p<0.05). 5. After cyclic loading, SS-II regular and wide implants showed higher detorque values than before(p<0.05).

This study was to investigate the value changes in Korean women by analyzing the ads of womens magazines. The contents of ads were classified into two types of values: general and consumption values. The general values, composed of inner-directedness and outer-directrdness, might predict consumer behavior in general. The consumption values, utilitarians and hedonic, were expected to affect the consumer purchasing attitude to a specific product. Factors affecting the cultural values were per capita income and womens social status. Total 2969 illustrated ads with verbal theme from 32 Korean womens magazines were used. The content analysis, chi-square test, logistic regression were done for the analysis. The results showed that inner-directedness was dominant general value in Korean womens culture and increased over time. Younger consumers were more inner-directed than older ones were, and inner-directed values increased with income growth. For the consumption values, utilitarian values were higher than hedonic ones and went up over time. For the product types, utilitarian ads were frequent in cosmetics while hedonic ads were high for apparels. Those results implied that Korean womens culture became more inner-directed with increased income. Also consumption values were likely to differ between product groups. Per capita income was shown to increase inner-directedness while womens social status was to increase outer-directedness.

Octanol/water partition coefficients of 52 chemicals were calculated using RP-HPLC estimation method and predicted by computer program, PCHEM. The result showed relationship between literature values and RP-HPLC observed values (relative coefficient r$^2$＝0.916), but the relationship of PCHEM values with literature values was lower than RP-HPLC value (relative coefficient r$^2$＝0.795). The average difference in partition coefficient between the RP-HPLC method and flask-shaking method was log Kow＝0.54, while the average difference between the values predicted form the computer program and flask- shaking method was log Kow = 0.36 Compared to octanol/water partition coefficients by 3 methods (Flask-shaking, RP-HPLC, computer prediction), the octanol/water partition coefficient values based on the flask-shaking method were very similar to the literature values, while the octanol/water partition coefficient values by RP-HPLC method without to consider the dead time, and computer prediction values did not significantly differ with the literature values.

Water quality simulation models include the difference between the measured and estimated values as an inevitable consequence because they represent the complicated natural phenomena as simplified mathematical equations. The major reason of the difference occurrence is due to the use of the imprecise values of the model parameters, but the parameter values are currently determined by the try and error method directly performed by humans. However, the use of this method requires many time and endeavor of humans, and generally does not obtain the most suitable parameter values. A method for deciding model parameter values is, therefore, developed in this study. The method minimizes the difference between the measured and estimated values and also distributes uniformly the measured values on the upper and lower sides of the line representing the estimated values. A user interface based on this method is also developed by using the Visual Basic 6.0 of Microsoft, and it can be operated in the environment of Windows 98/2000. In this study, the method for deciding model parameter values is applied for estimating the water quality of the stream Ko-heung. The results of the application show that the method, including its computer program, can effectively obtain the most suitable parameter values and also save many working time in comparison with the existing method directly performed by humans.

The purpose of this study is to examine the Korean social workers' level of social work values, advocacy attitude and advocacy intervention, and to verify the relations among social work education, social work advocacy and social work values by examining whether social work education influences social work advocacy and social work values, and whether social work values affect social work advocacy. Further, this study wishes to confirm not only the direct effect that social work education has on social work advocacy, but also how social work education indirectly influences social work advocacy through social work values on the social level as a mediator. The research of this study was conducted on 461 social work practitioners who have obtained either social worker licenses or mental health social worker licenses and are currently working in the field. As survey tools, this study utilized social work advocacy attitude, social work advocacy intervention, outcomes of social work education, social work values, self-esteem and locus of control. Collected data were analyzed by using SPSS/PC+ 11.5 for one-way ANOVA and t-test, Pearson's correlation, reliability analysis, exploratory factor analysis and multiple regression. To sum up the results of the study in terms of the research hypothesis, the research hypothesis was established according to the analysis method of the testing mediation of Baron & Kenny (1986) in order to examine whether social work values on the social level intervene between social work education and social work advocacy. The results of the hypothesis test confirm that social work values on the social level serve as a mediator variable.

The purpose of this study is to investigate the family values and the factors of satisfying family life. Throughout the study the changes of family values and marital satisfaction were examined. The results of the study are as follows; 1) Whereas the family values of people living in urban community were modernized to a great extent- in position of wife, role of husband and wife, preference between son and daughter, view on filial piety- the family values of people living in rural community were remained its traditional form. Form both areas modernization of family values was found in support of old parent. 2) Both Seoul and Andong showed the significant difference on family values according to subjects' education and age. In Seoul, the socio-economic level was influential factor in determining subjects' family values. 3) Marital satisfaction was found higher among people living in rural community than in people living in urban community. Since its very important not only to the individual but also to the society for a human being to be content in his surrounding , the reestablishment of the housewives family values should be followed so that other family members may approach the modernized family values.

P-values are often perceived as measurements of degree of compatibility between the current data and the hypothesized model. In this paper, a new concept of Bayesian p-values is proposed and studied under the non-informative prior distributions, which can be thought as the Bayesian counterparts of the classical p-values in the sense of using the concept of significance level. The performances of the proposed Bayesian p-values are compared with those of the classical p-values through several examples.

Information on the heating values of municipal solid wastes is very important in evaluating the feasibility of incineration and RDF (Refuse Derived Fuel) manufacture. This paper describes the forecasting methods about the lower heating values of municipal solid wastes. The lower heating values are forecast by the heating values of physical components. The municipal solid wastes consist of paper, food wastes, textiles, plastics, wood and rubber (contained leather). These are the physical components of municipal solid wastes.
