A Catechumenate for the Korean Methodist Church: Ressourcement, Formation and a Response to Secularism and Korean Traditional Religions

Research by Korean sociologists of religion indicates that Korean Protestantism has lost much of the spiritual vitality of preceding generations and that it increasingly shows the influences of Korean shamanism, Neo-Confucianism, and Western secularism and consumerism. Suggestions in the areas of homiletics and Christian social ethics have been offered to help steer the Korean Protestant churches away from these worldviews toward a more biblically-based course. Drawing upon and expanding these earlier studies and proposals, the current work recommends another method for developing a biblically-based, spiritually-revitalized, baptismally-shaped and ministry-committed Protestantism in Korea: a pre-baptismal adult catechumenate, in this case one designed for the context of the Korean Methodist Church. In order to produce a renewed catechumenal structure for Korean Methodism, adult catechumenal processes as well as baptismal theologies and rites are examined and analyzed from three principal sources: the first five centuries of the Christian church, and especially the mystagogical literature of the fourth century; the Roman Catholic Rite of Christian Initiation of Adults developed after the Second Vatican Council; and the United Methodist Church in the United States, both texts officially authorized by the denomination's General Conference and unofficial materials, among them resources for an adult catechumenate in the Come to the Waters series. In addition, previous and current practices of preparation for baptism in the Korean Methodist Church are identified and critiqued. From these findings a set of principles is put forward that guide the proposed catechumenal structure.

Cerebellar Learning in an Opponent Motor Controller for Adaptive Load Compensation and Synergy Formation

This paper shows how a minimal neural network model of the cerebellum may be embedded within a sensory-neuro-muscular control system that mimics known anatomy and physiology. With this embedding, cerebellar learning promotes load compensation while also allowing both coactivation and reciprocal inhibition of sets of antagonist muscles. In particular, we show how synaptic long term depression guided by feedback from muscle stretch receptors can lead to trans-cerebellar gain changes that are load-compensating. It is argued that the same processes help to adaptively discover multi-joint synergies. Simulations of rapid single joint rotations under load illustrates design feasibility and stability.

The Role of Edges and Line-Ends in Illusory Contour Formation

Illusory contours can be induced along directions approximately collinear to edges or approximately perpendicular to the ends of lines. Using a rating scale procedure we explored the relation between the two types of inducers by systematically varying the thickness of inducing elements to result; in varying amounts of "edge-like" or "line-like" induction. Inducers for om illusory figures consisted of concentric rings with arcs missing. Observers judged the clarity and brightness of illusory figures as the number of arcs, their thicknesses, and spacings were parametrically varied. Degree of clarity and amount of induced brightness were both found to be inverted-U functions of the number of arcs. These results mandate that any valid model of illusory contour formation must account for interference effects between parallel lines or between those neural units responsible for completion of boundary signals in directions perpendicular to the ends of thin lines. Line width was found to have an effect on both clarity and brightness, a finding inconsistent with those models which employ only completion perpendicular to inducer orientation.
