The issue of child care in family policy is one of the most important agendas. It is the primary task for a welfare state to form such conditions as socializing it to ensure labor rights and parental rights. The aim of this study is to review any controversies in the agenda of free choice in child care. But real 'free choice' comes true when all community members as individuals are able to enjoy their rights as both workers and parents without any restriction and sexual discrimination in the labor market. But in reality 'free choice' has not been realized in our society. This study is based on the analysis of these issues in free choice - the concepts of liberty, equity and equality, the role of the state, financial efficiency and the status of women in the labor market. Based on the analysis of the issues in accordance with the criteria, I suggest some policy recommendations: adequate and sufficient child care services, the introduction of univer sal child benefits and the expansion of public child care facilities.

The results of a numerical study on the performance of a propeller operating near a free surface are presented in this paper. The simulations are verified through comparison with experimental data, which was performed in a circulating water channel. The propeller performance as a function of the submerged depth was investigated. The effect of the propeller advance ratio on the wave patterns, flow structures around propeller, and thrust and torque of the propeller was also studied. Air ventilation was not observed for low advance coefficients. However, the simulations showed that wave pattern was strongly related to the tip vortex strength and inflow velocity. When air ventilation does not occur, the deduction of propeller thrust and torque increase for high advance coefficients.

Iksan Export Free Zone which was established for the export promotion, the employment augmentation, the technological improvement and the regional development promotion through the attraction of foreign direct investment is declining function with diminution of foreign direct investment, exportation and employment since the middle of the 1980s. The decline factor of the function was inherent in disregard of the necessary locational factors for Export Free zone's function promotion and without respect to conditions in a choice of location. And the present labor intensive industrial structure of region has some difficulties with a modification of Export Free Zone's industrial structure to a technology intensive industry. According to the lack of coherent policy, a limited plottage and a lack of the extensible space decrease the effect of agglomeration and economic of scale. And the lack of governmental policy to create a dynamic advantage comparative with an amelioration of the locational conditions of region diminish the regional attractive force to foreign direct investment.

An free-fall object is received only force of gravity. Movement that only accept gravity is free-fall movement, and a free-falling object is free falling body. In other words, free falling body is only freely falling objects under the influence of gravity, regardless of the initial state of objects movement. In this paper, we assume, ignoring the resistance of the air, and the free-fall acceleration by the height does not change within the range of the short distance in the vertical direction. Under these assumptions, we can know about time and maximum height to reach the peak point from jumping vertically upward direction, time and speed of the car return to the starting position, and time and speed when the car fall to the ground. It can be measured by jumping degree and risk of accident from car or motorcycle in telematics.

The monitoring of a free surface generated by waterjet cutting technology is very important for an efficient construction process. In this study, experiments using a laser sensor were performed to provide a data processing method and to determine optimized parameters. The experimental parameters here are the angular resolution, measurement distance, and free surface cutting shape. The results show that the monitoring resolution increases with a decrease in the angular resolution and the horizontal measurement distance and with an increase in the cutting (free surface) width. This laser monitoring method can be applied during the measurement of free surface shapes and depths in situ.

This study intends to propose a policy plan for the activation of the Busan Blockchain Regulation-Free Zone, which is selected by the government's comprehensive negative regulation policy. Unlike Europe and the United States, Korea is based on a positive regulation and aims at suppression, not activation. The Korean government proposed a transition to "comprehensive negative regulation" as a groundbreaking regulatory innovation policy to solve the problems of positive regulation. For this implementation plan, seven regulation-free zones were selected. Busan was selected as the Blockchain Regulation-Free Zone, and secured an opportunity to revitalize the stagnant regional economy based on the blockchain. This study is a policy study for the activation of the Busan Blockchain Regulation-Free Zone, and aimed to propose a method to create an industrial ecosystem with the discovery of a Busan-specific Blockchain service that can be commercialized in the Regulation-Free Zone.

The purpose of this paper is to analyze the free economic zone policy from the viewpoint of Policy Science. because of insufficiency on policy science of the previous researches for the free economic zone. So Trying on free economic zone policy from the viewpoint of policy science, the paper is shown the new proposal for free economic zone policy. For this trying, this paper used to the viewpoint of policy science; (1) the system of policy(policy process, policy content(pattern)), (2) the policy implementation(local government-central intergovernmental management). In the end, beyond the previous research on the free economic zone policy, shown on not only new viewpoints on the free economic zone, but also, the solutions of practical implementation for free economic zone on the free economic zone.

This study examined the influences of participation in the free semester on school life satisfaction and interest in classes and whether the effect persisted longitudinally. The participants were students from middle schools located in large cities: 451 students in the experimental group and 466 students in the control group. Only the students of the experimental group participated in the free semester. The data were collected at the end of the free semester for three years, and the results are as follows. First, the school life satisfaction of students in the experimental group was significantly higher than those in the control group until the second year but not in the third year. Second, there was no difference in interest in the main subject classes between the experimental and control groups until the third year. Third, students' interest in art and sports classes in the experimental group was significantly higher than those in the control group until the second year but not in the third year. These findings suggest that long-term planning and management of the institution rather than short-term introduction is required for the continuous effects of the free semester.

미국의 항공산업은 바야흐로 백화재방 전성기에 있다. 이것은 항공기의 제조, 운항 등 전분야에 걸쳐있으나 처음부터 이렇게 백가쟁명형은 아니었다. 항공기 제조업계가 최근에 와서 냉전 체제의 종식에 따라 구조조정이 불가피하여 지금은 유수 몇개사로 집중되고 있다. 그러나 운항회사의 경우는 약육강식의 경향이 없는 것은 아니지만 약 20여년 전부터 언제나, 어디서나, 어떤 운임 체계로나 설립도 자유이고 폐업도 자유라는 완전 자유 풍토가 되어있다.

The purpose of this study was to contrive the specific teaching plans based on the frame of 2007 revised science curriculum for applying open-inquiry lesson in real education situation and to research the effects of open-inquiry lesson on the student's science-related attitude, science process skill, and to investigate instructing teachers' cognition about open-inquiry. For this study, two fifth grade classes were chosen, one class was the experimental group, who were taught by open-inquiry based lesson, and another was the comparative group, who were taught by traditional method based lesson. The findings of this study were as follows: After open-inquiry lesson, the experimental group students came to enjoy open-inquiry learning and had the positive thought about it. After open-inquiry lesson, the experimental group marked higher mean score than the comparative group in science-related attitude's field but didn't showed the meaningful difference. On the other hand, in science process skill's field, the experimental group showed the significant higher improvement than the comparative one, especially in the subordinate area of basic science process skill. Finally, teachers who instructed students open-inquiry lesson thought open-inquiry lesson is the self-directed problem solving learning which raise the student's science process skill and interest. And the teachers thought the obstacles to instruct open-inquiry lesson are the lack of the student's cognition about open-inquiry and the insufficient circumstance for open-inquiry lesson. Therefore the teachers argued that the prerequisite for settling open-inquiry lesson successfully is to develope open-inquiry lesson curricula and teaching materials.
