The optical gain of InGaN/GaN multi quantum well (MQW) resonant-cavity light-emitting diode (RC-LED) with different Indium composition and well width in the multi-quantum well was investigated. The optimized optical gain was obtained by simulating active region InGaN/GaN with some test values of well width and Indium composition. By simulation tool, we could simulate on several cases, and then we got exact well width and Indium composition that makes optical gain maximum due to the short wavelength of 470 nm for blue light emission.

This study examined the influences of stress and academic self-efficacy on subjective well-being. The subjects were 191 4th-graders and 250 6th-graders. Data were analyzed by means of two-way ANOVA, Pearson's coefficients, and stepwise regression. Results indicated that : (1) There were age or gender differences for stress, academic self-efficacy, and subjective well-being. (2) Stress was negatively correlated with academic self-efficacy and subjective well-being, whereas academic self-efficacy was positively correlated with subjective well-being. (3) Stress and academic self-efficacy explained 43% of subjective well-being. Specifically, stress from parents was the most influential variable for positive affects, and self-regulatory efficacy was the most influential variable for positive efficacy and inter-relatedness.

In this paper, the well-conditioned observer is designed to be insensitive to the ill-conditioning factors in transient and steady-state observer performance. A condition number based on 12-norm of the eigenvector matrix of the observer matrix has been proposed on a principal index in the observer performance. For the well-conditioned observer design, the non-normality measure and the observability condition of the observer matrix are utilized. The two constraints are specified into observer gain boundary region that guarantees a small condition number and a stable observer. The observer gain selected in this region guarantees a well-conditioned and observable property. In this study, this method is applied to the Luenberger observer and Kalman filters for small order systems. In designing Kalman filters, the ratio of the process noise covariance to the measurement noise covariance is a design parameter and its effect on the condition number is investigated.

In this paper, the well-conditioned observer is designed to be insensitive to the ill-conditioning factors in transient and steady-state observer performance. A condition number based on $L_2-norm$ of the eigenvector matrix of the observer matrix has been proposed on a principal index in the observer performance. For the well-conditioned observer design, the non-normality measure and the observability condition of the observer matrix are utilized. The two constraints are specified into observer gain boundary region that guarantees a small condition number and a stable observer. The observer gain selected in this region guarantees a well-conditioned and observable property. In this study, this method is applied to the Luenberger observer and Kalman filters. In designing Kalman filters for small order systems, the ratio of the process noise covariance to the measurement noise covariance is a design parameter and its effect on the condition number is investigated.

Objectives: The Temperament and Character Inventory (TCI), initially developed by Dr. Cloninger in 1986, has been studied from various perspectives in many countries; however, its application in Korea has been limited due to a lack of information regarding the clinical use of integrative medicine. Methods and Results: A systematic review of previous studies on the theoretical development, structure, and content of temperament and character scales, as well as their stability and variability, is presented. In addition, the distinctive features of TCI as a biopsychosocial model and its clinical application regarding well-being, coherence therapy, and person-centered medicine were systematically reviewed. Discussion and Conclusion: The promotion of well-being with Cloninger's personality model and its importance for integrative medicine were discussed. This study would contribute to the clinical application of TCI in Korea.

Company strategy that considers market trend becomes a more important key to success in the new product development. Well-being as a present social trend has created a huge new product market. but with increasing number of camouflaged well-being products that are not fulfilled consumer needs. The purpose of this study is to understand the concept of well-being products from a consumer point of view an to find five consumer values based on the consumer value model of Sheth, Newman, and Gross(1991) through conducting content analysis from semi-structured individual In-depth Interviews. This study has a significance in identifying the detailed consumer value attributes and influence factors by collecting practical and reach qualitative data in the lack of systematic research of domestic well-being market and its products from a consumer point of view. The result of this study will be a foundation of future quantitative researches and provide a guideline to companys' well-being marketing strategy.

In this paper we describe a robust method of improving precision in monitoring high energy ion implantation processes. Ion implant energy accuracy was measured in the device manufacturing process using an unpatterned implanted layer on an intrinsic p-type silicon wafer. To increase Rs sensitivity to energy at the well implant process, a PN junction structure was formed by P-well and deep N-well implants into the p-type Si wafer. It was observed that the depletion layer formed by the PN junction was very sensitive to energy variation of the well implant. Conclusively, it can be recommended to monitor well implant processes using the Rs measurement method described herein, i.e., a PN junction diode structure since it shows excellent Rs sensitivity to variation caused by energy difference at the well implant step.

Human capital theory and social capital theory provide a framework for analyzing economic well-being. The purpose of this study was to investigate the effects of human capital and social capital on the economic well-being of the elderly. The data from the 1st wave of KLoSA (Korean Longitudinal Study of Aging) were used (n=3,426). The major findings were as follows: First, human capital and social capital are both resources that can contribute to increasing the economic well-being of the elderly. Second, the effects of human capital on the economic well-being of the elderly were relatively higher than the effects of social capital. Third, the relative contributions of human capital and social capital to increasing economic well-being varied by sex, age, and region. Based on the empirical results, the implications for social investment in human capital and social capital were provided.

This study was to identify variables which were related with middle aged women's identification of child mother-role burden and psychological well-being and to investigate the relationships of mother-role burden and psychological well-being in mid-life. The research data were collected from 578 who were 40-59 year old women in Seoul. The major findings were as follow; (1) the level of middle age women's identification of child was very high and the level of mother-role burden was moderate. the level of psychological well-being was slightly high. (2) Mid-life women's psychological well-being was related to education level income and job. (3) Identification of child was related to educational level having job and income. And mother-role burden was influenced only by education level. (4) Middle aged women's identification of child was positively related mother-role burden. Mother-role burden was negatively related to psychological well-being in mid-life. These findings represented middle aged mother in our society had considerable burden of child but their psychological well-being was not low. Possibly it is due to the fact mothers regard their burden of child as acceptable duty.
