The purpose of this research was to develop an un-tact group counseling program to deal with the conflicts in the relationship of unmarried couples and to verify the effect of the program for improving emotional cognition and emotion regulation of unmarried couples. The research procedure consisted of the program development step and the program verification step, and in detail, 8 steps of program development processes were established. The subjects of the research were 11 unmarried couples, and 4 group were organized. The group counseling program was conducted once a week (2 sessions), a total of 10 sessions for 5 weeks. The effect was analyzed quantitatively and qualitatively. As a result of quantitative analysis, the participant's relationship satisfaction was significantly improved and there was a significant change in some relationship emotional schemas of participants. As a result of qualitatively analysis through participant's program review, participant's emotional understanding and the couple relationship were improved, and the group effect of the couple group counseling was found. Finally, the significance and limitations of this study were presented.

The purpose of this study is to analyze local cultural festivals hosted contact-free in the corona era and to suggest the direction for sustainable festivals in the post-corona era. To this end, by analyzing the cases of well-known festivals held contact-free in 2020 and 2021, we tried to get implications for the festivals in the post-corona era from there. As a result of this study, contact-free festivals had the following characteristics. First, the on-tact method, which produces and transmits a video or allows interaction through real-time participation, was prominent. Second, in order to compensate for the shortcomings of the contact-free method, various efforts have been made to enable on-tact experience by making and delivering experience kits in the case of experiential elements of the festival in advance. Third, communication was secured through real-time comments, and fourth, products were sold through the Internet and live commerce channels, and a certain effect was obtained. In particular, in the case of online festivals, there is a problem of loss of the sense of place of the festival, but there are cases of online festivals with more participation than offline festivals. It is judged that the problem of how to achieve this will become a reference material for the future development of contact-free festival contents.

We will introduce our new concept deposition system for SMOLED manufacturing in this conference. This system is designed to deposit organic and metal material to downward to overcome the limit of substrate size and process tact time hurdle for OLED mass production, and is organized with organic deposition chamber, substrate pre-cleaning chamber, metal deposition chamber and encapsulation system. These entire process chambers are integrated with linear type substrate transfer system. We also compare our new SMOLED manufacturing system with conventional vacuum deposition systems, and show basic organic thin film property data, organic material deposition property data, and basic device property.

Japan Jisso Technology Roadmap 2001 (JJTR2001) was published by JEITA in April 2001. Future electronic products request further higher assembly technology (ex. Finer pitch packages & components, 3D assembly, etc.) to reduce size and improve performance of the electric products. For LSI Packages, finer ball pitch technology and finer chip connection technology will be developed. For electric components, further size reduction will be developed. For Jisso (assembly) machine, finer pitch assembly and short tact time technology will be developed. Mr. Utsunomiya will present PCB roadmap next.

Recent construction projects, characterized by its complication and high-tech, requites highly efficient management efforts. Among others, labor management is very important due to various trades and increasing number of activities. Along with advanced information technology, Web-based construction site management systems are widely adopted in order to improve the efficiency of construction management. However, such information systems have mainly 2 (two) shortcomings. One is that the existing systems were developed and implemented not in subcontractor-centered way but in main contractor-centered way, though the daily construction information is mainly generated, gathered and reported by subcontractors. As a result, subcontractors seldom have access to such information systems. The other is that loss or omission of information may uclw during the information processing process, in which subcontractors have no direct access to such information system. This becomes a major reason of losing the reliability of the information in daily construction report. As a solution for these problems, this paper suggests a Web-based information system that is subcontractor-oriented and also suitable for tact schedule management.

A hierarchical planning strategy for dextrous manipulation of multifingered hands with soft finger contact model is proposed. Dextrous manipulation planning can be divided into a high-level stage which specifies the position/orientation trajectories of the fingertips on the object and a low-level stage which determines the contact forces and joint trajectories for the fingers. In the low-level stage, various nonlinear optimization problems are formulated according to the contact modes and integrated into a manipulation planning algorithm to find contact forces and joint velocities at each time step. Montana's contact equations are used for the high-level planning. Quasi-static simulation results are presented and illustrated by employing a three-fingered hand manipulating a sphere to demonstrate the validity of the proposed low-level planning strategy.

An analytical thermal model of HESG(higt efficiency speed grinding) is presented, in which the heat flux to workpiece in grinding zone is modeled as time dependent and moves along a slope decided by contact chord(approximation of con-tact arc). By matching the maximum surface temperature of workpiece derived from this model to the maximum surface temperature of grinding wheel composite as done in Lavins simple thermal model, the relation of maximum surface tem-perature and energy partition of workpiece to grinding speed is obtained. In high speed grinding, as wheel speed increases, energy partition decreases with no regard to table speed.

In this paper, we developed an automated program for the modeling and simulation of three-dimensional roller gear cam mechanisms. The three-dimensional modeling for a roller-gear cam employs coordinate transformations based on the con-tact condition. the wire frame modeling followed by the shading technique using triangular meshing elements incorporat-ed the to reduce the number of data and computational load. Computer simulations for two kinds of products for rollger-gear cam mechansim illustrate the relative motion between the modeled roller-gear cam and a turret and thus show the effectiveness of the proposed modeling.

현대 산업사회는 첨단 산업기술의 발전으로 많은 생산시설이 자동화되고, 작업형태 또한 생산성을 높이기 위한 택트타임(tact time) 분석으로 작업이 더욱 세분화되고 있으며, 이로 인해 작업자의 특정 신체부위만 집중적으로 사용하는 단순 반복작업이 크게 증가하고 있다. 그 결과 작업자가 어깨, 허리, 손목 등에 통증을 호소하는 근골격계질환이 계속 증가하는 추세에 있다. 노동부 자료[1]에 의하면 근골격계질환자 수가 2000년 1,009명, 2001년 1,598명이고 2002년 상반기만 1,069명으로 점차 증가 추세를 보이고 있으며, 2002년 한해 동안만 ○○중공업 253명, ○○조선 158명, ○○자동차 78명의 근골격계질환자가 발생하여 산업재해 판정을 받음으로써, 이로 인한 노동력 상실 및 막대한 비용 손실로 인해 심각한 사회적인 문제로 대두되고 있다[2].(중략)
