This paper presents a new method for automatically calibrating robot link (Kinematic) parameters during the process of estimating motion parameters of a moving object. The motion estimation is performed based on stereo cameras mounted on the end-effector of a robot manipulator. This approach significantly differs from other calibration approaches in that the calibration is achieved by simply observing the motion of the moving object (without resorting to any other external calibrating tools) at numerous and widely varying joint-angle configurations. A differential error model, which expresses the measurement errors of a robot in terms of robot link parameter errors and motion parameters, is developed. And then a measurement equation representing the true measurement values is derived. By estimating the above two kinds of parameters minimizing the difference between the measurement equations and the true moving pattern, the calibration of the robot link parameters and the estimation of the motion parameters are accomplished at the same time.

"Know thyself" is one of the most famous ancient proverbs. We need to know ourselves to understand others and find true ourselves. Enneagram is one of the tools we can use to do it. It has drawn more and more attention from people by its effectiveness and spiritual depth. It has been widely promoted in both business management and spirituality contexts. It has many concepts to be understood. Holy ideas and virtues are understood to be restored to find our true self which is the purpose of using the Enneagram. Actually, holy ideas and virtues are similar with character qualities which comprise character. In this paper, holy ideas and virtues are matched with corresponding character qualities. To promote transformative process of character development through Enneagram, an app was designed. It has 2 levels. Level 1 is to find personality type and show corresponding character qualities of 9 personality types to users. Level 2 is to find subtypes and Enneagram Levels of Development for further purpose.

Toegye pursues a life of pleasure, joy and nobility. Anyone who is a scholar shall feel a joy in learning and practicing. However, not everyone can enjoy true pleasure or true calling through self-cultivations. Everybody wants "a joy of distant friends' visitations." But most of Confucian scholars prefer forests as a place of learning and self-cultivation. Toegye especially likes a forest life and then gives same value to walking as to reading. "Not to be angry even if not recognized" must be a high stage of self-cultivation. Toegye does not pursue fame or glory and always resign into a country life. His life-time resignation makes him obtain great after-death fame and glory. Thus, nobody feels jealousy against him but adores him.

This study was conducted to explore college students' implicit identification with others powerful or powerless, and implicit association of self-enhancement & authenticity with their relationships with others powerful or powerless. The study was based on measuring 3 sorts of IAT: an explicit identification test, RWA, & RISC. The results were summed up as follows: Students identified their selves with others more powerful than others powerless; expressed self-enhancement when they were with powerful others; and associated 'true' with relationship with others powerful. Men with high RWA & women with low RWA identified their selves more with others powerful; low RWA & high RISC groups' associated relationship with others powerful to 'true' and others powerless to 'false' more rapidly. These results were discussed in terms of structure of authoritarianism, SEM, relationship with others powerful and powerless.

We propose an extended version of multi-step algorithm of self-calibration of interferometric optical testing instruments. The key idea is to take wavefront measurements with near equal steps in that a slight angular offset is intentionally provided in part rotation. This generalized algorithm adopts least squares technique to determine the true azimuthal positions of part rotation and consequently eliminates calibration errors caused by rotation inaccuracy. In addition, the required numbers of part rotation is greatly reduced when higher order spatial frequency terms are of particular importance.

Objective : To explore the relationship of social class and health behaviors with self-reported morbidity. Methods : The 1995 General Household Survey in Korea was used to investigate self-reported morbidity. Logistic regression was used to examine the relationship of social class and health behaviors with self-reported chronic disease and perceived general health. Results : For chronic disease and general perceived health, age adjusted odds ratios were higher for manual workers, lower-educated group as well as those in the lower income group; this held true for both men and women. Health behaviours had little effect or the relationship between social class and morbidity. The relationship between health behaviors and morbidity was very weak. The lower social class expressed higher levels of negative health behaviors, although this relationship appeared to be very weak in Korea. Conclusions : This study suggests that an understanding of health differentials that addresses the issue of social inequalities in Korea is required.

Objectives : The purpose of this study was to provide information about Maumgongbu to meet the needs of people by analysing the concept of Maumgongbu in group counseling. Methods : This study was conducted using Walker and Avant's Concept Analysis Strategy. Dictionaries, Wonbuddhism's Kyunjions and literatures, and participants' journals were reviewed after enrolling in Onsarm maumgongbu group counseling. Results : The attributes of the Maumgongbu include emotion, object, self-reflection, attribution, and creativity. The antecedents of "Maumgongbu" are the conditions arising from negative emotions. The Maumgongbu helps people find the emotional causality of their inner self by self-reflecting, getting out of false belief, restoring positive emotions, maintaining healthy and warm relationships with oneself, family, friends and society. Above all, the Maumgongbu makes people experience tranquility and true happiness and activate their positive energy or power. Conclusions : If there is a clear indication of linkage to principles, attributions, precedents and consequences, and empirical referents to any of Maumgongbu programs, there is no doubt that our understanding of the human mind and lives will be greatly enriched. Furthermore, self-discipline and steadfast complements give us calmness, peacefulness and better quality of life.

Self-sufficiency has been recognized as one of the most important welfare goals for women in the domestic violence field since the welfare reform in the U.S. A qualitative research design was conducted to explore the self-sufficiency experience of Korean-American single mothers with the history of domestic violence in poverty. The meaning of 'self-sufficiency' to participants is that a continuing task or process in life to move toward being independent mentally as well as economically. Their challenges toward self-sufficiency include the period of restoration of their potentials for self-sufficiency destroyed by domestic violence victimization and divorce, and the period of developing their sustainability for self-sufficiency. Their needs for 'help and support similar to care from the woman's parents' home', 'welfare service of select and concentration', 'mature dependency and self-sufficiency', and 'self-sufficiency from survival to dream come true' to cope with the challenges formentioned are reported. Concrete strategies for the development of self-sufficiency polices and services sensitive to immigrant single mothers with the history of domestic violence are suggested.

Pheromone (PHB)-receptor (RCB) interaction in the mating pheromone response pathway of Lentinula edodes was investigated using synthetic PHBs. Functionality of the C-terminally carboxymethylated synthetic PHBs was demonstrated by concentration-dependent induction of a mating-related gene (znf2) expression and by pseudoclamp formation in a monokaryotic strain S1-11 of L. edodes. Treatment with synthetic PHBs activated the expression of homeodomain genes (HDs) residing in the A mating type locus, and of A-regulated genes, including znf2, clp1, and priA, as well as genes in the B mating type locus, including pheromone (phb) and receptor (rcb) genes. The synthetic PHBs failed to discriminate self from non-self RCBs. PHBs of the B4 mating type (B4 PHBs) were able to activate the mating pheromone response pathway in both monokaryotic S1-11 and S1-13 strains, whose B mating types were B4 (self) and B12 (non-self), respectively. The same was true for B12 PHBs in the B4 (non-self) and B12 (self) mating types. The synthetic PHBs also promoted the mating of two monokaryotic strains carrying B4-common incompatible mating types ($A5B4{\times}A1B4$). However, the dikaryon generated by this process exhibited abnormally high content of hyphal branching and frequent clamp connections and, more importantly, was found to be genetically unstable due to overexpression of mating-related genes such as clp1. Although synthetic PHBs were unable to discriminate self from non-self RCBs, they showed a higher affinity for non-self RCBs, through which the mating pheromone response pathway in non-self cells may be preferentially activated.

Now we are faced on the national policy to aim at the nationwide logistics center in North-East Asia. To come true, Korean ports developments policies are better off going towards integrated governmental supportive system build-up, activated infra-structures, back-yard developments, legal and institutional system, international co-ordination networks system, customer-oriented port management system like one-stop services, and multi-variate financing resources. Above all, Related governmental institutions strongly have self-confidences and devotional efforts to make them all implemented not losing own way.
