One of the most fundamental problems an ageing society faces is the role deprivation and social isolation of older persons. In this respect, restoring the roles and social status of older persons by promoting their social participation is considered crucial to enhancing their quality of life. From such viewpoint, this study aims at analyzing the social participation of older persons from an actor-oriented perspective. To do so, this study classifies various social participatory activities into representative activity types and analyzes the socio-demographic determinants of each activity types. The findings show that the participatory activities of Korean older persons could be classified into four types : volunteer-focused, religion-focused, occupation-focused and kyungrodang-focused social participation. Also, it has been found that the determinants of each social participation types, including the non-participatory type, differs according to the socio-demographic condition of each older person, thus indicating that differentiated policy measure is required to enhance the activites of Korean older persons.

On the other hand, the fiber orientation at the surface and middle layer of the sheet controls the bending stiffness of paperboard. Therefore, a reliable measurement of paper surface fiber orientation gives us a magnificent tool to investigate and predict paper curling and cockling tendency, and provides the necessary information to fine-tune the manufacturing process for optimum quality. Many papers, especially heavily calendered and coated grades, do resist liquid and gas penetration very much, being beyond the measurement range of the traditional instruments or resulting inconveniently long measuring time per sample. The increased surface hardness and use of filler minerals and mechanical pulp make a reliable, non-leaking sample contact to the measurement head a challenge of its own. Paper surface coating causes, as expected, a layer which has completely different permeability characteristics compared to the other layers of the sheet. The latest developments in sensor technologies have made it possible to reliably measure gas flow n well controlled conditions, allowing us to investigate the gas penetration of open structures, such as cigarette paper, tissue or sack paper, and in the low permeability range analyze even fully greaseproof papers, silicon papers, heavily coated papers and boards or even detect defects in barrier coatings! Even nitrogen or helium may be used as the gas, giving us completely new possibilities to rank the products or to find correlation to critical process or converting parameters. All the modern paper machines include many on-line measuring instruments which are used to give the necessary information for automatic process control systems. Hence, the reliability of this information obtained from different sensors is vital for good optimizing and process stability. If any of these on-line sensors do not operate perfectly as planned (having even small measurement error or malfunction), the process control will set the machine to operate away from the optimum, resulting loss of profit or eventual problems in quality or runnability. To assure optimum operation of the paper machines, a novel quality assurance policy for the on-line measurements has been developed, including control procedures utilizing traceable, accredited standards for the best reliability and performance.

The development of the biomedical science and technology has extended an argument about a status in constitutional law of unborn human life and a protection of the potential human life to that of an embryo and a gamete beyond a fetus. This argument has been focused on whether we should provide unborn or potential human life with human dignity and the right to life that are guaranteed by the constitutional law altogether or separately. If the right to life is given to unborn or potential human life, on what grounds can we restrict this right. Those who argue for the unity of the right to life with human dignity and the inseparability of those two claims that the right to life in itself should be guaranteed absolutely. According to the constitutional law, however, any constitutional right of the human person within the protection of essential part of the right can be compared with each other and restricted with some valid reasons from the legal perspective. This measure is unavoidable in reality because one right can come into conflict with another right frequently. Since fetus and embryo are in a process of developing into the human person, it is difficult to think that they are the same with the human person. For that reason, it is hard to consider that the right to life of fetus or embryo is the same with that of the human person. However, since a fetus has a special status as a potential human person, and an embryo also has a special value as a potential fetus upon an implantation, the right to life of fetus or embryo should be judged differently according to the stage of their development. A study on a constitutional status and protection of a fetus and an embryo is essential because unborn or potential human life is the origin of human person. Therefore, we have to make much account of their right to life and seek the legal respect for their inherent value.

Purpose : The purpose of this study was to describe the current status of 119 EMT to violence experiences in Korea. Method : The number of 119 EMT in this study 2522. Self-administering questionnaire data were collected from April 27 to March 8 in 2009. Collected data were analyzed using SPSS 14.0 program. Real number, percentage, mean and standard deviation were calculated. Pearson correlation coefficient was analyzed. Result : 119 EMTs experienced 95.32%-verbal insults, 61.54%-violence aggression, 60.51%- potential violence, 38.70%-physical assault. Within 30 days from the most recent period of violence experienced verbal insults and violence aggression-51.07%, potential violence and physical assault-48.41%. The patients(50.59%) and the patients and patient's carers(38.26%) proved to be violent offender. The main reason of violent act was drug or alcohol addiction(56.15%). Recent exposure to violence was 34.82% by 7 point reward of stress level. 5-point scale showed the average of experiences of violence. Response average of emotional reactions was 2.66 points and that of physical reaction was 2.18 points. Social reaction was 2.06 points. Conclusion : This study was based on the violence experience of 119 EMT. It is necessary to prevent the violence from emergency scene. So we proposed the preventive measure against violence as well as critical incident stress debriefing(CISD). Policy for CISD and stress management will be implemented in the near future in Korea.

Using a subsample of 3,409 unmarried smothers and their children from the Fragile Families and Child Wellbeing study, the present study examined the cross-lagged effects of unmarried fathers' involvement on their children's behavior problems. Father involvement was used as a latent variable to measure the frequency of fathers' visits to the child, fathers' instrumental support, and their supportive parenting. Both variables of father involvement and child behavior problems were repeatedly measured at child ages 3, 5, and 9 to estimate their trends over time. The results indicated that fathers' more active engagement in parenting at child ages 3 to 5 reduced behavior problems in children at ages 5 to 9. Further discussions include programs and services to support unmarried fathers through education and training opportunities for effective parenting, relationship skills, and conflict resolutions as well as policy strategies to encourage their continuous involvement in the lives of their children.

Our luck is brute if we cannot choose or control it and, thus, we are not responsible for it. Our luck is optional if we can choose or control it and, thus, we are responsible for it. Egalitarian justice at least demands brute luck be fully neutralized. If, however, brute luck is not fully neutralized and possibly accumulated, what will happen to the Gini coefficients as a measure of inequality due to brute luck? By simulating brute luck under various combinations of the rate of accumulation and the level of, what I call, leximin-redistribution, I obtain the Gini coefficients for the distribution of the accumulated and, then, redistributed brute luck. The level of the leximin-redistribution determines the negative or positive relation between the rate of accumulation and the Gini coefficient. The minimum leximin-redistribution level that generates the negative relation between the rate of accumulation and the Gini coefficient, depends on the characteristics of the starting-point distribution of brute luck. The sooner the leximin-redistribution is ushered in, the lower the minimum level becomes. The so-called 'Growth First Redistribution Later' policy may hurt victims of brute bad luck.

Analyzing the inner meaning and expression of philosophy by analyzing the composition, symbolic expression, and style of the film with high artistic perfection, which contains the spirit of the times, considers human beings through society and history, and raises awareness of life and the present generation. It will be a very meaningful and valuable study in film as art. The movie 'Rome' was cut into the rest of the public's mind by being tempered, hidden and omitted, and the color was black and white. Many aesthetic attempts can be found through symbolic images expressing the ironic message of maid's daily life as a race, capital, socially oppressed history. It can be seen that he expresses his own authorism visual language by drawing symbolic expressions through many contrasts and symbolic expressions through objects. The analysis of commercial films containing these artistic values is expected to help in the future production as a measure of the progress of art films and precedents of authorism expression techniques.

This study measures how Korean shipping policies influence the expansion of the country's merchant fleet using system dynamics. It uses various indexes as factors influencing the gross tonnage of the Korean merchant fleet, such as the Baltic Dry Index, Howe Robinson Container Index, China Containerized Freight Index, and Worldscale Index, as well as the US dollar-Korean won exchange rate, world merchant fleet statistics, and the debt ratio of Korean shipping companies. After establishing the simulation model, the mean absolute percentage error is found to be less than 10%, confirming the accuracy of the model. Therefore, a sensitivity analysis is conducted to measure the influence of the selected shipping policies, including the gross tonnage of vessels registered under the Korean second registry system, loans of publicly owned financial institutions to shipping companies, ship investment fund, and the number of shipping companies participating in the tonnage tax scheme. The sensitivity analysis reveals that the influence of vessel tonnage and loans to shipping companies is the most significant, while that of the number of companies participating in the tonnage tax scheme is minimal.

Purpose: With economic development and prolonged longevity, the level of health and health disparities have became growing concerns for individual and society as well. Since youth's health status are influenced by households' socioeconomic status and associated with heath status in later stage of life, assessing health inequality in the youth is a significant step toward lessening health disparity and promoting health. We measured health inequality in high school students and decomposed it into health factors. Methods: The subjects included 3,787 high school students of 12th graders from the Korea Education and Employment Panel (KEEP) in 2004. True health status was assumed as a latent variable and estimated by ordered logistic regression model. The predicted health was used as a measure of individual health after rPSraling to [0,1] interval. Total health inequality was then measured by Gini coefficient and was decomposed into health factors. Results: Health inequality in high school students was observed. Of total health inequality, 44% was explained by biological factors such as body mass index (BMI) (32.5%) and gender (13.5%). Behavioral factors such as smoking, drinking, physical activity, hours in bed and hours of computer ussge added to 11.7%. Household income and work experiences explained 5.6% and 8.8%, respectively. School satisfaction explained 14.6%. Other school related factors such as self-assessed achievement and experience of being bullied accounted for 15.5%. Conclusion: Among the health factors, biological factor was the most important contributor in health disparity. Other factors such as health behaviors, socioeconomic factors, school satisfaction and school related factors exhibited somewhat similar magnitude. For policy purposes, it is recommended to look into modifiable factors depending BM, gender and school surroundings.
