The purpose of this study was to investigate the relationships of parental attachment and self-differentiation with fear of intimacy perceived by college students. The data of the study were collected through self-administered questionnaire method with 187 male and 159 female college students. The major results of this research were as follows. First, there were significant differences in the level of attachment with parents according to parent's marital statue, living standard, and father's education level. Second, there were significant differences in the level of self-differentiation across sex, age, parent's marital statue, living standard, and parental's education level. Third, the level of attachment with parents was positively correlated with self-differentiation, indicating that the greater the level of attachment with parents, the higher the degree of self-differentiation. Fourth, fear of intimacy was negatively associated with parental attachment and self-differentiation, showing that the greater the degree of fear of intimacy, the lower the lever of attachment with parents and self-differentiation. Finally, multiple regression analysis result reported that emotional cutoff among the four self-differentiation subscales was the most powerful variable predicting the fear of intimacy. The results were shortly discussed in terms of some implications for education and counseling with college students.

Resent removal work for road signs has been labor intensive and required times since it has been done manually using shaving type equipment. While traditional process is conducting, there are traffic jams caused by the passing control, and happened unexpected accidents to workers working at dangerous road circumstance. Besides, in current shaving method, there are high potentialities on the air pollution as well as the explosive accident occurred by using a propane gas. So, as an alternative, we have studied to develop the automatic erasing equipment made up with a high pressure water-jet system and automatic control system, mobile system; Wate-rjet system consists of an intensifier and nozzles to give a high pressure and spray on the sign, and automatic control system is composed of one axis robot using a hydraulic servo actuator controlled by a lever, And as a mobile system, a truck plays an important role for the transport of equipment and the forward movement in a removal process. In this paper, we have analyzed the characteristics of road signs and have investigated current erasing methods in the field. And we have organized and designed automatic erasing equipment, and we have made a basic experiment to find out the optimal spray condition as like the spray distance, spray angle and injection pressure.

Proposed Manta-type Unmanned Undersea Vehicle(UUV) turned out to have the tendency of dynamic instability in vertical plane, and moreover to have that of so strong dynamic stability in horizontal plane as to cause another problem in turning motion due to negative value of sway damping lever. The authors discussed the changes in appendage design for improvement of dynamic stability of UUV in vertical and horizontal planes. As a result, the dynamic stability in vertical plane was improved by increasing the area of horizontal stern planes. and the dynamic stability in horizontal plane was also improved by removal of lower vertical plate and by adjusting the area and position of upper vertical plate simultaneously.

This study aims to grasp invisible yet dynamic systemic structure that influences the general procedure of national R＆D investment system in Korea using "system dynamic methods and to suggest policy lever. Various conflicting situations, 'R＆D investment paradoxes' in myopia investment and principal-agent problems etc, arise when the government decides R＆D investment area and makes indispensable choice. Difficulty in the decision can be amplified due to misalignments among decision on adequate amount of R＆D investment ("strategic loop"), R＆D system ("structural loop") and acceptance and realization by R＆D laboratories and theirs researcher ("efficacy loop"). Results of modeling and simulation of korea national R＆D investment system with consideration of three causal loops show the switching pattern dynamically, in which form of technologies shifts from one to another stage like paradigm shift, when the R＆D investment reaches a certain stork. R＆D investment increases are directly not liked to R＆D productivities because of delays and side effects during transition periods between different stages of technology development. Thus, It is necessary to develope strategies in order to enhance efficiency of technological development process by perceiving the switching pattern.

The role of the social environment for any activity is crucial as it prompts new ideas and plays a role of lever for entrepreneurial longevity and creating value through social wellbeing. The lack of entrepreneurship related knowledge in Pakistan has taken the challenge of lesser entrepreneurial activity as compared to other counterpart Asian countries and ranked 138 out of 189 countries on the level of ease of doing business. The study aims to investigate the social environment as a mediator among idea generation, business creation, financing decision and entrepreneurial activity by utilizing quantitative approach. In order to achieve the objective, a total of thirty eight items scale was self-administered for data collection. A non-probability, snowball sampling technique was employed and assembled a total of 300 complete responses through online and paper based surveys as per information provided by the chamber of commerce of three regions namely; Sukkur, Hyderabad and Karachi Sindh, Pakistan. The data analysis result strongly supported the main research question as the entrepreneurial activity increased up to 43.8% after applying social environment as a mediator. This research can help to enhance entrepreneurial activities in Pakistan by creating awareness to support entrepreneurs at social level for entrepreneurship.

A micro-macroscopic analysis on the conduction-controlled directional casting of Al-Cu alloys is performed, in which emphases are placed on the microstructural features. In order to facilitate the solution procedure, an iterative micro-macroscopic coupling algorithm is developed. The predicted results show that the effect of finite back diffusion on the transient solidification process in comparison with the lever rule depends essentially on the initial concentration of an alloy. In the final casting, the eutectic fraction is distributed in an increasing-decreasing-increasing pattern, each mode of which is named the chill, interior and end zones. This nonuniformity per se suffices to justify the necessity of this work because it originates from the combined effects of finite back diffusion and cooling path-dependent nature of the eutectic formation. As the cooling rate is enhanced, not only the influence depths of boundaries narrow, but also the eutectic fractions in the chill and interior zones increase. In addition, it is revealed for the first time that the micro segregation band is formed in response to a sudden change in cooling rate during the directional casting. An increasing change creates an overshooting band in the eutectic fraction distribution, and vice versa.

Compared to other types of power, hydraulic energy is the most commonly used for heavy vehicles and ships because it has fewer location and space constraints, and its controllability can be maintained even under adverse conditions. Operators have controlled a main control valve of ship winches by pushing or pulling the lever, which is directly connected to the spool. However, because of the spatial arrangement, the importance of remote control valves has emerged. In this paper, experiments of the hysteresis characteristics were performed by analyzing the remote-control valve using a valve tester and RA2300. The validity was verified by comparing with the analytical model using SimulationX as the hydraulic analysis program. This study examined the effects of the spool's notch (Non, End-mill, and Spherical) and the effects of stiffness and pre-load of the spool spring on Spool stroke, open area, and hysteresis characteristics. It is considered possible to reduce the cost and the, trial and error process in designing remote-control valves in the future.

The stability curves are very important data to decide the seaworthiness of all kinds of ships among waves. Both statical and dynamical stability curves on a rectangular coordinate system have broadly been handled at ship yards or at the government concerned, up to data. As concerns a method of obtaining a statical stability curve on polar coordinate system, the papers were presented once. Also, it is of use to research the dynamical stability curve on polar coordinate system. Author treated of the dynamical stability curve by four different methods, and tried to set the stability indicator inboard, adopted those proposals, in order to give some aids for good navigation on the sea. Fig. 1. shows a drawing method in case of the position of centre of buoyancy can be previously pointed out on the line corresponding to its inclination. Fig. 2. shows a method used a statical stability curve on polar coordinate. Fig. 3. shows a method obtained by the most simplified means. Fig. 4. shows dynamical stability curve made by geometrical expression method, instead of dynamical lever. A simple stability indicator which was mechanized above characteristics is attempted by author as shown Fig. 5 and Fig.6. It is demanded at hand, for more advanced improvement of such indicator.
