All aspects of clothing, including color, are a visible form of expression that carries invisible value. The purpose of this work is to study the expression of resistance in the white Hanbok in modern culture, specifically after the 1980s. Koreans have traditionally revered white color and enjoyed wearing white clothes. In Korea, white represents simplicity, asceticism, sadness, resistance against corruption, and the pursuit of innocence. This paper looks at: (i) the universal and traditional values of the color white, (ii) the significance of traditional white Korean clothing, (iii) the resistance characteristics of white in traditional Korean clothes, and (iv) the aesthetic values of white Hanbok. The white Hanbok often connotes resistance when it is worn in modern Korea. It is worn in folk plays, worn by shamans as a shamanist costume, worn by protestors for anti-establishment movements, and worn by social activists or progressive politicians. The fact that the white Hanbok has lost its position as an everyday dress in South Korea (instead symbolizing resistance when it is worn) is an unusual phenomenon. It shows that the white Hanbok, as a type of costume, is being used as a strong means of expression, following a change in the value of traditional costumes as it take on an expressive function.

Purpose: The purpose of this study was to define the concept for psychological insulin resistance in the Korean population with diabetes. Methods: The Hybrid model was used to perform the concept analysis of psychological insulin resistance. Results from both the theoretical review with 26 studies and a field study including 19 participants with diabetes were included in final process. Results: The preceding factors of psychological insulin resistance were uncontrolled blood glucose and change in daily life. The concept of psychological insulin resistance was found to have three categories with 8 attributes such as emotional factors (negative feeling), cognitive factors (low awareness and knowledge, low confidence for self-injection) and supportive factors (economic burden, dependency life, embarrassing, feeling about supporters, feeling of trust in, vs mistrust of health care providers). The 8 attributes included 30 indicators. Conclusion: The psychological insulin resistance of population with diabetes in Korea was defined as a complex phenomenon associated with insulin therapy that can be affected by emotional factors, cognitive factors, and supportive relational factors. Based on the results, a tool for measuring psychological insulin resistance of Koreans with diabetes and effective programs for enhancing insulin adherence should be developed in future studies.

In this paper, we fabricated Cu/Mn alloy shunt resistor with low resistance and thermal stability for use of mobile electronic devices. We designed metal alloy composed of copper (Cu) and manganese (Mn) to embody in low resistance and low TCR which are conflict each other. Cu allows high electrical conductivity and Mn serves thermal stability in this Cu/Mn alloy system. We confirmed the elemental composition of the designed metal alloy system by using energy dispersive X-ray (EDX) analysis. We obtained low resistance below $10m{\Omega}$ and low temperature coefficient of resistance (TCR) below $100ppm/^{\circ}C$ from the designed Cu/Mn alloy resistor. And in order to minimize resistance change caused by alternative frequency on circuit, shape design of the metal alloy wire is performed by rolling process. Finally, we conclude that design of the metal alloy system was successfully done by alloying Cu and 3 wt% of Mn, and the Cu/Mn alloy resistor has low resistance and thermal stability.

This paper proposes a method that can be used for the resistance estimation of a PWM (Pulse Width Modulation)-driven solenoid. By using estimated solenoid resistance, the PWM duty ratio was compensated to be proportional to the solenoid current. The proposed method was developed for use with EHB (Electro-Hydraulic Braking) systems, which are essential features of the regenerative braking system of many electric vehicles. Because the HU (Hydraulic Unit) of most EHB systems performs not only ABS/TCS/ESP (Electronic Stability Program) functions but also service braking function, the possible duration of continuous solenoid driving is so long that the generated heat can drastically change the level of solenoid resistance. The current model of the PWM-driven solenoid is further developed in this paper; from this a new resistance equation is derived. This resistance equation is solved by using an iterative method known as the FPT (fixed point theorem). Furthermore, by taking the average of the resistance estimates, it was possible to successfully eliminate the effect of measurement noise factors. Simulation results showed that the proposed method contained a sufficient pass-band in the frequency response. Experimental results also showed that adaptive solenoid driving which incorporates resistance estimations is able to maintain a linear relationship between the PWM duty ratio and the solenoid current in spite of a wide variety of ambient temperatures and continuous driving.

[Purpose] The purpose of this study was to investigate the effects of a high-fat high-sucrose (HFHS) diet on previously reported adaptations of cardiac morphological and contractile properties to resistance training. [Methods] Twelve-week-old rats participated in 12-weeks of resistance exercise training and consumed an HFHS diet. Echocardiography and skinned cardiac muscle fiber bundle testing were performed to determine the structural and mechanical adaptations. [Results] Compared to chow-fed sedentary animals, both HFHS- and chow-fed resistance-trained animals had thicker left ventricular walls. Isolated trabecular fiber bundles from chow-fed resistance-trained animals had greater force output, shortening velocities, and calcium sensitivities than those of chow-fed sedentary controls. However, trabeculae from the HFHS resistance-trained animals had greater force output but no change in unloaded shortening velocity or calcium sensitivity than those of the chow-fed sedentary group animals. [Conclusion] Resistance exercise training led to positive structural and mechanical adaptations of the heart, which were partly offset by the HFHS diet.

Panax Ginseng C. A. Meyer which has been known for more than 2000 years, occupies a particular place in folk medicine as so called tonic remedy. The brief pharmacological action of Ginseng complied from the numerous reports can be summarized as adaptogenic effect to be increased nonspecific resistance. Among the various components of Ginseng, the effective components has been known Ginseng butanol fraction as so called Ginseng saponin. In order to study on the effect of the Ginseng butanol fraction which influences spontaneous activity by CNS drugs in mice. Experiment of response was measured the change of spontaneous activity by CNS drugs in which mice were treated Ginseng butanol fraction. A method of measuring spontaneous activity in mice used by counting the number of times which were interrupted a beam of light. Results of experiment can be summarized as follows: 1. In case of administrating Ginseng butanol fraction for 1 day, stimulating effect of Ginseng was observed in spontaneous activity by caffeine in comparison with the control. at the first, but after 45 minutes no significant change was observed. 2. In case of administrating Ginseng butanol, fraction for 5days, decreasing tendency was observed in spontaneous activity by caffeine. 3. In case of administrating Ginseng butanol fraction for 10days, marked decrease was observed in spontaneous activity by caffeine in comparison with the control. From the experiment on the increased dose of caffeine, nonsignificant change was observed in comparison with caffeine and sodium benzoate 25mg/kg group. 4. A state of increased resistance was lasted until 5 days, and after 10 days it was disappeared. 5. Otherwise, nonsignificant change was observed for chlorpromazin HCl in comparison with the control. 6. From this result, 10 days administrating of ginseng butanol fraction appeared to have increased resistance in mice against caffeine.

The general pattern of adaptation in the appendicular skeleton with aging is that the subperiosteal apposition of bone occur along with endosteal absorption. This remodeling of diaphysis to a cylinder of larger diameter is hypothesized to serve a mechanical compensatory unction by increasing the moment of inertia as the cortex thins with aging. These findings is only true of the diaphysis of long bone. Measuring the area and inertia at each section of femur, the age-related change of proximal emur and diaphysis is observed. After screening by physical and radiological examination, 200 normal Korean adults divided 5 groups in both male and female based on age. Twenty persons were in each group. One femur in each person was analyzed using CT images. femur scanned with 60 to 80 slices and this images were digitized. Then 2-D images were reconstructed into 3-D images. Using the nonlinear method, normalization and interpolation technique, 7 locations of interest (trochanteric area: 1, 2 subtrochanteric area: 3, 4, isthmic area: 5, 6, 7) were determined. On the each cross section at each location, the area (total, cortical and medullary) and 5 inertia of moment were measured. The results were analyzed statistically. With aging, significant area change occurred mainly in diaphysis and female. In trochanteric area, no significant change was noted. With aging, total and medullary area were increased, but cortical area was not changed. In diaphysis, lateral bendingresistanceincreasedsignificantly. No inertia change was noted in trochanteric area. Anteroposterior bending resistance was constant with aging. In more than age 60, total area and medullary area were larger than that of others. Lateral bending resistance was higher especially in diaphysis. In diaphysis, with aging, the decreased properties is compensated with the increased lateral bending resistance by geometric remodeling. In trochanteric area, no compensation occur. With aging, especially in more than age 60, the higher rate of trochanteric fracture is expected.

상변화 메모리 소자 제작 공정의 단위 스텝인 최종 열처리의 온도가 상변화 메모리 소자 특성에 미치는 영향을 고찰하였다. $Ge_2Sb_2Te_5$ (GST) 박막을 활성 물질로 하는 기공(pore) 구조의 단위 상변화 메모리 소자를 제작하고, $160^{\circ}C$에서 $300^{\circ}C$까지의 온도 범위에서 최종 열처리를 실시하였다. 상변화 메모리 소자의 SET 저항에서 RESET 저항으로의 셀 저항 변화 양상은 최종 열처리 온도에 따라 큰 차이를 나타내었다. 정상적인 상변화 메모리 동작 특성을 얻을 수 있는 임계 열처리 온도가 존재하며, 열처리 온도가 그 온도에 비해 상대적으로 높거나 낮은 경우에는 소자가 오동작하거나 불안정하게 동작하는 것을 확인하였다. 이러한 열처리 온도의 효과는 열에너지에 따른 상부전극-GST 박막-발열층 다층 구조의 열적 안정성과 밀접한 관련이 있는 것으로 보인다.
