This paper reviewed the relationship among safety-specific transformational leadership, safety motivation, and safety participation, and the mediating effect of safety motivation between transformational leadership and safety participation. Based on the responses from 233 employees, the results of multiple regression analysis appeared as follow; 1) charisma, individual consideration, intellectual stimulation, and inspiration effect positively on safety motivation. 2) safety motivation effects positively on safety participation. 3) safety motivation mediates fully between charisma/inspirationand safety participation. 4) safety motivation mediates partly between individual consideration/intellectual stimulation and safety participation.

방사선 로봇 시스템은 X-Ray를 이용하는 로봇 기반 자동 치료 시스템으로 방사선 치료계획 시스템, 방사선가속기, 방사선 치료 로봇, 호홉 추적 시스템, 스마트베드로 구성된다. X-Ray를 이용하는 치료 시스템인 관계로 안정적인 제어가 요구되며, 환자의 호흡에 의한 병소 위치 변위 발생에도 X-Ray를 병소에 정확하게 정량 조사해야한다. 본 논문에서는 방사선 로봇 시스템을 구성하는 서브시스템 간의 데이터 송수신 동기화와 시스템 안정성 확보, 그리고 시스템 통합을 위한 문서 작업을 획기적으로 줄이면서 시스템 통합을 단시간에 수행한 과정에 대하여 기술한다.

철극형동기기를 무부하상태로 전환을 할때 갑지기 2상간에 단락이 돌발한 경우 다른 개로상단자에 유기되는 open-phase voltage의 과도상태를 구명하는데 본 논문의 목적이 있다. 우선 전기자전압의 직축분과 횡축분을 구하기 위하여 Blondel씨가 제창한 이론을 matrix form으로 전개하여 그의 기본전압방정식을 확립시키고 이어서 상간단락전류를 구해가지고 개로상단자에 유기되는 이상전압, 즉 open-phase voltage의 치를 e$_{a}$ =e$_{d}$cos.theta.-e$_{q}$ sin.theta.+e$_{0}$의 관계식에 의거해서 구해보자는 것이다. 논설상의 편의를 도모키 위해 몇가지 가정을 마련하는 것이 순서라고 본다. 제동권선이 없는 철극동기기를 취급하고 포화현상을 무시하며 직축상에 주계자가 존재하는것으로 간주하며, 전기자회로의 저항은 근소치임으로 시정수에 한애서만 영향을 주는 것 이외에는 계산상에서 이를 무시하고 역시 계산에 나오는 무든 양은 per-unit notation을 사용하고 영상분은 고려하지 않으며 대표적인 동기기정수를 x$_{d}$=0.78, x'$_{d}$=0.21, x$_{q}$ =0.48 및 E=1로 정해서 구명해보자는 것이다.

This study examined the relationships between multiple intelligences as cognitive factors and affective factors of learning motivation and academic self-concept. The data were collected from 276 4th grade elementary school students and analyzed by correlation, multi-variate analysis, and step-wise multiple regression. Results were that (1) multiple intelligences, learning motivation, and academic self-concept had statistically significant correlations among themselves. Multi-variate analysis showed that intra-personal intelligence explained 58.6% of the linear combination of learning motivation and academic self-concept. (2) Intra-personal intelligence explained 29% to 58% of learning motivation and its sub-factors of achievement motivation, internal locus of control, self-efficacy, and self-regulation. (3) Intra-personal intelligence, logical-mathematical intelligence, musical intelligence, and inter-personal intelligence were explanatory variables for academic self-concept and its sub-factors.

The purpose of this study is to investigate the relationship between the social values and the clothing motivations for a group of female college students in Seoul, Korea. Through this study, the followings were found : 1. A significant relationship was found between the social values and the five dothing motivations : Decoration, Modesty, Protection, Belongingness, Self-Esteem. 2. A significant relationship was found between the clothing motivations and the environmental factors concerning school : college type (coeducational college or women's college), major. grade. 3. A significant relationship was found between the clothing motivations and the environmental factors concerning family : father's income, father's educational level, order among sisters.

BAG-O-MATIC PRESS-라고 하면 근대의 타이어 가류를 제한 기계이다. 인건비가 높은 미국은 더욱 성역화를 지향하여 이 가류기를 개발했던 것이다. 그것에 대해 종전후의 일본은 노동력이 풍부했던 고로 실업대란의 일환으로서 이 자동가류기의 설치를 거절해왔다. 연이나 일본도 이것을 장기적으로는 주저하고 있을 수 없었다. 우선 부릳지스톤타이어가 B.O.M을 도입해서 성역화에 성공, 이어서 전사가 이것의 채용에 이르렀다. 그를 위해서의 주역을 맡은 것이 신호(고오배)제강소이다. 동사가 미국으로부터 동기술을 도입, 국산화를 시작해서 벌써 13년, 생산대수도 2천대를 돌파했다는 것이다. 그렇기는 해도 LOADER의 문제, POST INFLATOR의 문제등, 일본에서의 완전화에의 도정도 간단하지는 않았다. 하나 타이어관계자로서 이 가류기가 타이어계에 공헌한 정도의 큼을 잊어서는 안되겠다. 앞으로도 타이어 기술의 진보와 함께 더욱 발달된 가류기 개발에의 노력도 계속될 것이고 또 요구도 되고 있다.

The proposed algorithm can always set up the optimal threshold value regardless of channel characteristics using an adaptive threshold establishment method that determines the threshold level according to channel noise power, and then it uses the specially designed training symbols that can make the algorithm's estimation performance be less sensitive to power delay profile variation in a multipath channel. In result, the estimation performance of the proposed technique is less affected by channel characteristic variation.

Collaboration and assistance among peer learners are essential factors for successful learning outcomes. However it is important to investigate students' preferences for computer problem solving methods and interrelationships, since students tend to solve problems more and more by themselves. This is because of the importance of giving appropriate instructions to students. In this context, this paper shows the analysis of the preferred methods and interrelationships of studnets' preferences upon encountering difficulties during computer usage by collecting data from 231 students in K national university of education. As a result, the result shows that students tend to solve problems without asking as they have higher abilities in computer usage, which was also shown to increase along with their grade levels. Furthermore, it showed that students who have family members and relatives, and who are using the internet are more satisfied with their problem solving. Lastly, it is possible to grasp the computer problem solving network within the department by using social network analysis, so it can be used as reference data for selecting the peer learners, which will help to operate the customized computer education practice.

This study was intended to analyze the visitors' awareness of the cultural asset value of Marsh Plants of Daesong-ri, Haman (Natural Monument 346) as well as the requirement for use and management of the only marsh designated as a National Monument in order to provide the implication for future management. The result of the analysis showed that the public awareness and the awareness level of the natural monuments were low and that the motivations for visiting were the experience and education of nature, rest and leisure, and experience of the cultural heritage, in that order. The analysis of motivation for visiting according to the awareness level showed that the group with a high awareness level of the Marsh Plants or the group that thought highly of its cultural asset value tended to visit it more for the experience of nature or the experience of the cultural heritage than for simple resting. For usage, the visitors required the basic amenities such as guide board and the more active promotion. They also preferred the discovery of traditional resources using the marsh plants and the experience of nature. Both local residents and outside visitors pointed out the lack of systematic management policy and lack of communication with local residents as the main problems. They recognized that the policy that balanced the preservation and usage through the cooperation of various stakeholder including local residents must be established and applied in the field to ensure proper management.
