In this article we have applied Schweizer & Sklars t-norm based similarity measures to classification task. We will compare results to fuzzy similarity measure based classification and show that sometimes better results can be found by using these measures than fuzzy similarity measure. We will also show that classification results are not so sensitive to p values with Schweizer & Sklars measures than when fuzzy similarity is used. This is quite important when one does not have luxury of tuning these kind of parameters but needs good classification results fast.

The realization of high quality robot control needs the improvement of computing speed of controller. In this paper, parallel processing method is considered for this purpose. A S/W algorithm for task scheduling is developed first, and then, an appropriate H/W structure is proposed. This scheme is applied to calculate inverse kinematics of PUMA robot. The simulation results show that the computing time when using three 8086/87's is reduced to 4.23 msec compared to 10 msec in case using one 8086/87.

A software package CARDS for general purpose robot design, control, and simulation has been developed and is presented here. CARDS (Computer Aided Robot Design and Simulation) consists of a collection of standardized subroutine modules that carry out typical kineamatic, dynamic, and control computations so that the user only needs to write a main program that further defines a particular robot configuration and the task to be performed. It provides users a complete simulation environment, so that it will be a valuable engineering tool for mechanical designers as well as electric control designers.

It is one of the essential task to determine the absolute location of mobile robot during its navigation. In this paper we propose an algorithm to calculate the distance and orientation of camera from landmark through the visual image of stripe typed landmark. Exact closed form solution of camera location is obtained with the correspondences from vertical line on mark plane to the intersection point of projected line with horizontal axis of image plane. It needs only one line image information, so that location determination can be processed in real time.

This study is to categorize five types of conflict handling styles that employees can take when conflict occurs. The five types are integrating, avoiding, dominating, obliging, and compromising. I found these factors that explain conflicts handling styles divided them into organizational structure, task group functioning and need styles and how certain factors explain different kinds of conflict handling styles without other factors. To measure conflict handling styles, this study used the scale of conflict style devised Rahim. Data were collected by the survey method from employees engaged in the service industry located Seoul, the Province of Gyeonggi, and the Province of Gangwon. In addition, in order to prove my hypothesis, I used hierarchical regression analysis method to find the pure explanation that each factors have without multicollinearity. According to the study's result, in a person's type of needs, if the need for achievement is high, they prefer integrating style. In contrast, if the need for achievement is low, they prefer avoiding style. Also, if the need for affiliation is high, the employees prefer compromising style. But if the need for affiliation is low and the need for dominance is high, the employees favor dominating style. However, in task group functioning, group homogeneity, group cohesiveness, and group goal clarity are high, or the confidence in peers and management is high, the employees prefer obliging style to other conflicts handling styles. As well as if group homogeneity, group cohesiveness, and group goal clarity are high, it was found that they prefer compromising style. Also, if the role conflict that is related to organizational structure is serious, employees prefer obliging style, but they have weakenss in explanation. To sum up these results, if the employees have obliging style that shows lack of concerns over themselves and at the same time, have high concerns to others, is affected by task group or organization. And we can infer that the other conflicts handling styles are effected by personal characteristic.

클러스터와 같은 분산 시스템에서 초기 작업 배치 시, 할당할 프로세스의 자원 요구량을 정확히 예측하여 작업을 분배할 수 있다면 보다 나은 시스템 성능을 얻을 수 있게 된다. 이 때 임의의 작업을 적절한 호스트에 배치하기 위해서 자원 기반 초기 작업 배치 (resource-based initial job placement) 기법은 그 작업의 자원 사용량을 미리 예측할 필요가 있다. 하지만 잘못된 자원 예측은 동적 부하 분산 시스템의 성능을 크게 떨어뜨리는 원인이 된다. 따라서 본 논문에서는 잘못된 예측에 의한 문제를 해결하기 위해 새로운 부하 기준을 제안한다. 새로운 부하 기준을 사용한 자원 기반 초기 작업 배치 기법은 프로세스의 유형에 관한 사전 지식 없이도 동작하는 장점을 가진다. 실험을 통해 본 논문은 동적 부하 분산 시스템에서 제안하는 방식이 기존의 방식에 비해 향상된 성능을 가짐을 보인다.

Purpose: This study aimed to investigate changes in gait variables depending on whether a task was performed using a smartphone while walking on a ramp. Methods: The participants of this study were 41 college students attending U University located in Gyeongju City, Gyeongsangbuk-do. In this study, gait variables were measured during ramp gait while using a smartphone to perform a task and during ramp gait without performing such tasks. In other words, four walking conditions were used: 1) walking up a ramp, 2) walking up a ramp while using a smartphone to perform a task, 3) walking down a ramp, and 4) walking down a ramp while using a smart phone to perform a task. Gait variables were measured using a gait analysis tool (Legsys; BioSensics, USA), and stride time, stride length, stride velocity, cadence, and double support were analyzed. The order of measurements was randomized to control for order effects due to repeated measurements. Results: The comparative analysis of gait variables according to the presence or absence of smartphone use during ramp gait showed that there were significant differences in stride time, stride length, and stride velocity during both ramp ascent and ramp descent (p < 0.05). In both ramp ascent and ramp descent, stride time increased when walking using a smartphone, compared to when walking without using a smartphone (p < 0.05). However, in both ramp ascent and ramp descent, stride length and stride velocity were decreased when walking using a smartphone compared to when walking without using a smartphone (p < 0.05). Conclusion: The study results showed that the use of a smartphone during walking can affect safety. Therefore, it is necessary to improve the awareness of risks associated with walking while using a smartphone, and further research needs to be conducted in various environments and with different ramps.

According to the Korean National Statistics Office(KNSO), more than 90% of Korean adolescents aged from 15 to 19 use a computer for more than 10 hours per week. The KNSO also reveals that this age group mostly uses a computer in their own room, followed by a commercial place. It is also found that the house for the adolescent is not simply a physical environment, but is rather a center of their personal lives where their personal and social developments are formed. Therefore, the physical environment where computers are used is very important. The purpose of this study was to investigate the characteristics and needs of computer furniture for the adolescent. Data were collected through self-administered questionnaires and 414 adolescents participated. The results of this study are as follows: (1) Most of the respondents(42%) used the internet for less than one hour per day and it was used for community visits and operations, game, and chat rooms. (2) The desks where computers were used were specially designed and made of wood. Chairs were typically height adjustable with armrests and there was no task lighting for computer use. (3) The preferences of computer furniture were chairs with a high back, casters and armrests. The overall satisfaction of individual computer rooms was low. However, it is important for an adolescent to be provided with a user friendly environment for sound growth and development. Further study is therefore needed regarding environmental variables through empirical study.

이 연구의 목적은 '길 안내' 와 같은 문제해결 과정을 통해 나타나는 학생들의 공간적 문제해결 전략 및 개인차를 밝히는 것이다. 방문객의 길 안내를 위해 학생들이 캠퍼스에 세운 간이 표지판의 위치를 분석하였다. 학생들은 표지판의 위치로 급격한 방향 전환이 필요한 갈림길이나 길 안내의 출발, 도착지점을 선호하였으며, 경로를 선정할 때 효율성, 환경적 특성, 방문객의 심미적 만족감 등 다양한 요인들을 고려하였다. 또한 대부분의 학생들이 방문객의 예상 이동 경로를 따라 일렬로 간이 표지판을 세운 반면, 몇몇 학생들은 복수의 경로를 설정하는 전략을 사용하였다. 한편 동일한 과제를 실내에서 수행하게 했을 때, 실내에서 수행된 과제의 표지판들이 실외의 경우보다 균등한 간격으로 분포하는 특징을 보였다.

Recent changes in health problems as well as the health delivery system demand expanding nursing roles to improve quality care and at the same time provide cost-effective health services. Nursing leaders of the future will be expected to be excellent care givers who are well prepared as researchers and managers and administrators. The purpose of developing an ND program is to train nursing leaders for the future. The program objective are to demonstrate the role as 1) an advanced practitioner who will provide theory based practice 2) a researcher and manager The target population of the ND program is as follows : 1) Nurses with a BSN degree who are seeking to advance on the career ladder 2) Non-nursing BS, BA graduates who are seeking nursing as a second career 3) Transfer students who are mature and motived to be nursing leaders It is believed that the ND program would meet the diverse needs for potential students, for their role in nursing and the health delivery system and create a meaning and challenging position in the profession of nursing. A task force team was organized to develop the ND program and its activities are as follows; 1) Information on ND programs were collected from 3 universities and reviewed 2)An advanced education needs assessment was completed and it was found that 87.6% of the subjects responded positively about advanced degree work. 3) A tentative curriculum for an ND program was developed. It is a great challenge to develop a new program for nursing however, it is also our task and responsibility to further the development of nursing.
