하수정(HA, Soo-jeong) 역사비평사 2013 역사비평 Vol.- No.102
According to a survey in 2012, Olof Palme was most admired Swedish politician. Swedish society has traditionally been dominated by the concept of “lagom”, which means moderation where political decisions are reached through social corporatism. However, Palme’s strong leadership of the country led to his Social Democratic Workers party being termed Palme’s Party. His power and personal charm differentiated him from other politicians and enabled him to make astute political decisions in the face of traditional opposition, and made him the most popular politician in Sweden. On becoming Prime Minister in the late 1960’s, Sweden’s economic boom was beginning to slow down. The partnership between the Swedish Trade Union Confederation and the Swedish Employers Association, which had developed from the Saltsjobaden Agreement, was on the point of dissolution. Palme, who was regarded as a radical Prime Minister, stated that his aim was to maximize freedom for everyone. He believed that there would be no freedom without equality - an idea that had been inspired by his experience in the U.S. in his early 20s. Palme expanded welfare coverage based on tax increases which redistributed wealth, and introduced a series of labour protection acts. With his optimistic belief in human progress, he declared that solidarity, not market-based competition, would make society better. That is why he was cautious about market liberalism advocated by the Conservative party and tried to maintain the primacy of politics. As a 43-year-old Prime Minister, the firmest foundation of his leadership was public opinion and strong popular support. That was why he emphasized media exposure and public speech. In this way Palme redefined politics as an activity for every citizen rather than an agenda-shaping process of political parties. After several decades, Olof Palme still gives us insights as a politician with philosophy, virtue and the art of politics.

High power light emitting diode(LEDs), a strong candidate for the next generation general illumination applications are of interest. With major advantages of power saving, increased life expectancy and faster response time over traditional incandescent bulb, the LEDs are rapidly taking over many applications such as LCD backlighting, traffic light, automotive lighting, signage, etc. The increased electrical currents used to drive the LEDs have focused more attention on the thermal management because the efficiency and reliability of the solid-state lighting devices strongly depend on successful thermal management. There exist some problems that are caused by heat generation in the LED package, such as wire breakage, yellowing of epoxy resin, lifted chip caused by reflow of thermal paste chip attach and interfacial separation between LED package and silicon resin. The goal of this study is to analyze high power LED thermal properties of using pulsating heat pipe.

The main purpose of this study was to explore the variables predicting mothers' parenting attitudes in Korean-Japanese multi-cultural families in comparison to Korean families. Differences in parental beliefs, life-satisfaction and parenting attitudes between these two groups were also examined. Data were collected via questionnaires from 110 Japanese and 168 Korean mothers of young children. Results revealed that mothers' beliefs on value of child and parental role, life-satisfaction and parenting attitudes were different across the families. Costed-concept of child and low life-satisfaction predicted 'shaming' and 'coercive' parenting for Japanese mothers whereas parental role beliefs as an 'authority' figure predicted 'shaming' parenting for Korean mothers. Life-satisfaction was most influential to predict 'affectionate-rational' parenting for both group.

Bubble jet loop heat pipe is a newly devised variation of heat pipe in which heat is effectively transported by the latent heat of evaporation and condensation as well as the heat capacity of circulating working fluid. The circulatory and oscillating motion of the working fluid becomes possible by the motion of bubble jet which is generated at a narrow circular gap. These bubbles are condensed at the condensing section. Bubble jet loop heat pipe makes it possible to carry heat long distances upward and horizontal directions. Because Its structure is a very simple and a low cost, it is available for the floor heating, vinyl house heating, the defrosting of heat pump system and home refrigerator.

The purpose of this study is to improve thermosyphon type heat pipes which don't operate in the horizontality. The inclination is very important parameter to operate heat pipes. Especially when the angle of inclination is about zero, the heat pipes don't operate well. Because of the reason, uses of heat pipe were quite restricted. But it is different in bubble jet pulsating loop heat pipe. Bubble jet pulsating loop heat pipe operate well in the horizontality. The heat pipe forces to evaporate the refrigerant to make bubble through heater. It is consist of one heating part creating bubble and one rounded U tube type radiator. Those are unified in the heat pipe. This study shows about optimized refrigerant charging rate is in the tube and inclination angle of heater.
