To improve the luminous efficacy of PDPs, an AC PDP with new metal electrode structure is suggested. Operating voltage margin, power consumption, luminance, luminous efficacy, addressing jitter and ICCD image of test panel with proposed structure are measured, to compared with performances of the conventional ITO structure and proposed structures. To enhance luminous efficacy, we designed new structure which have asymmetric metal electrode structure. The experimental results show that the suggested structure shows luminance to maximum 89% and luminous efficacy to maximum 107% compared with conventional ITO standard structure. In addition, proposed structures with asymmetric electrode show low power consumption by $2{\sim}3%$, high luminance by $5{\sim}7%$, and high luminous efficacy by $2{\sim}3%$ compared with proposed symmetric electrode structures.

We have introduced fourth generation PDPs last year. The performance of these PDPs is the highest level among TV displays. At the same time the power consumption of them has reached to the lowest level among FPDs (Flat Panel Displays). High panel luminous efficacy and low address power are necessary for the reduction of total power consumption. Following technologies have been developed and applied to the fourth generation PDPs. High panel luminous efficacy: T-shape electrode, waffle rib structure, high Xe content gas Low address power; CLEAR driving method, etc.

The design of road lighting is aiming illuminance and luminance requirements for road lighting. In the process, various factors associated with luminaires such as luminous efficacy, light distribution, mounting height, spacing and maintenance factor are considered. However, there has been no restriction on lighting power density. In this study, lighting power density has been comparatively analyzed through a study of related data and a result of measurements on domestic roads. And, it has been analyzed by simulation results for road in which lighting conditions are variable. In terms of the limitation on power density for road lighting, road lighting can be designed using high efficacy lighting systems for energy saving.

Purpose: We were to identify the differences of "Job stress" and "Depression scores" in the divided groups by self-efficacy. And the factors affecting Depression scores were analyzed. Method: This study was conducted from July 2006 to September 2006. Collected 295 surveys were used in this study among 311 surveys since 16 surveys offered insufficient data. SPSS for Windows 10.0 was used to analyse the data. Result: We identified the factors of "Occupational climate", "Job control", "Job demand" as affecting the depression scores in the lower self-efficacy group by the multi-variables statistical analysis. And this statistical model had 12.5% explainable power. Also, the factors of "Occupational climate" were identified as affecting the depression scores in the higher self-efficacy group. And the statistical model had 9.0% explainable power. Conclusion: In the lower self-efficacy group, the scores of the job stress and depression were significantly higher. Therefore, in the lower self-efficacy group, the self-efficacy promotion programs should be needed for prevention of the related occupational diseases. The factors related job stress were identified as affecting the depression scores in both lower and higher self-efficacy groups. Therefore, job stress management program should be prepared for stress loading workers.

Inductively coupled plasma is commonly used for electrodeless lamp due to its ease of plasma generation. Optical characteristics significantly depend on the RF power and gas pressure of the plasma. This paper describes the measurement of luminous efficacy as a function of RF power and gas pressure with a goal of finding optimal operating conditions of the electrodeless lamp. The gas pressure was varied from 10 [mTorr] to 100 [mTorr] and the RF power was varied from 10 [W] to 120 [W]. It was found that the luminous flux tends to be decreased when argon pressure is increased, and the luminous flux is increased as RF fewer is increased. It was also found that the luminance efficacy is high when the argon pressure is low and when the RF power is low.

Purpose: The purpose of this study was to investigate the effects of Tai Chi exercise program on physical fitness, pain, and self-efficacy in patients with osteoarthritis. Method: A preexperimental research design was applied to 22 subjects who dwelled at a welfare institution in C-city and agreed to participate in this study. The Tai Chi exercise was conducted with a duration of 60 minutes per session twice a week for 9 weeks. Outcome measures were physical fitness($VO_{2}max$, strength, flexibility, foot power, agility, balance), pain, and self-efficacy. Data were analyzed by descriptive statistics and paired t-test. Result: After participating in the Tai Chi exercise program, the subjects showed significant improvements in strength, agility, balance, pain and self-efficacy. But there were no significant differences in $VO_{2}max$, flexibility and foot power. Conclusion: The results showed that Tai Chi exercise would partially improve physical fitness and be effective for pain reduction and self efficacy as well. Further studies are needed to confirm the effects of Tai Chi exercise on physical fitness.

This paper investigates the light output characteristics of an electrodeless H-discharge lamp. The existing cylindrical fluorescent lamps were wound around with an induction coil of varying size, and were driven by RF power. The light output and the luminous efficacy were measured according to variations of the induction coil gap and the lamp power, respectively. The experimental results show that the luminous efficacy of the lamp is as much as existing electrodeless lamps and the luminous efficacy of lamps are high between 10W and 20W. Theoretical analyses using computer simulation show that the circuit matching is easier in the external coil configuration than in the internal one, and that the current and the power distributions near the coil are shower in t.

본 연구에서는 과학적 자기효능감, 과학적 자기효능감의 원천, 창의적 성향의 학년과 성별에 따른 차이를 살펴보았다. 연구 대상은 수도권에 소재한 3-6학년 초등학교 학생 495명이었다. 과학적 자기효능감은 학년과 성별에 따라 차이는 없었다. 과학적 자기효능감 원천은 성별에 따른 차이는 없었으나 학년에 따른 차이는 나타났다. 대리적 경험과 생리적 상태에 대한 점수가 3-4학년이 5-6학년보다 유의미하게 높았다. 창의적 성향에서도 성별에 따른 차이는 없지만 창의적 성향 중 동기와 모험심은 3-4학년이 5-6학년보다 유의미하게 높았다. 또한, 과학적 자기효능감의 원천들 중에서는 생리적 상태 점수가 가장 높고, 언어적 설득 점수는 가장 낮은 것으로 나타나 선생님이나 부모님, 친구들의 칭찬과 격려가 충분하지 않았음을 알 수 있었다. 과학적 자기효능감에 미치는 변인들의 영향력을 살펴본 결과, 성공에 대한 경험이 가장 큰 설명력을 가지고 있었다. 두 번째로 자기효능감 원천 중에 언어적 설득의 설명력이 높았고, 세 번째로는 창의적 성향 중 인내가 설명력이 높았다. 이러한 과학적 자기효능감에 영향을 미치는 변인들의 영향력이 학년과 성별에 따라서 약간 상이한 것으로 나타났다.
