This paper presents a novel bio-mimetic quadruped walking robot with a waist joint, which connects the front and the rear parts of the body. The new robot, called ELIRO-1(Eating LIzard RObot version 1), can bend its body while the legs is transferred, thereby increasing the stride and speed of the robot. The waist-jointed walking robot can move easily from side to side, which is an important feature to guarantee a larger gait stability margin than that of a conventional single rigid-body walking robot. We design the mechanical structure of the robot, which is small and light to have high movability and high degree of human friendship. In this paper, we describe characteristics of the waist joint and leg mechanism as well as the analysis using ADAMS to select appropriate actuators. In addition, a hardware and software of the controller of ELIRO-1 are described.

This study was performed in oder to investigate to dietary behavior, perceived stress and their correlations of University students. The number of subjects was 549 and the results of this study are as followed: Only 13.9% of students-20% of male students, 10% of female students-exercise regularly. Regular exercise and health condition had no statistical relationship in this study. 83.9% of subjects had experience of alcohol drinking (19.4% of male students, 7.3% of female students). Many students replied that they drink alcohol 1∼2 times per a week. 24.4% of students-only 2.6% of female students-were smoking and great number of smokers were drinking also. The BMI of 46.7% of subjects were in normal range. 48.2% were in under weighted and 5.1% were in over weighted or obesity. The stress factor of University students were analyzed into 12.

This study examined relationships between peer variables and externalizing behavior problems of 290 4th and 5th grade children in elementary school. The children completed the Friendship Quality Scale and the peer nomination questionnaire. Parents and teachers rated behavior problems of children using the Connors' Rating Scale. Results indicated that rejected children had more behavior problems than popular, average, or neglected children. Socio-emotional supports from a close friend and satisfaction with the friend were negatively related to behavior problems. Behavior problems were mainly predicted by low peer acceptance, and behavior problems of rejected children were negatively and strongly related to socio-emotional supports of a close friend. In conclusion, peer rejection was a risk factor and a friend's support was a protective factor for externalizing behavior problems in 4th and 5th graders.

The main body of research literature on peer relations has focused on its effects on children's psychosocial and emotional development from preschool period to adolescence. Topics of the research generally consist of peer acceptance/rejection, friendships, and peer victimization. In the review of domestic and international research conducted since late 1990, research trends and issues are described in this paper. Findings suggest some measures in interventions, prevention, and policies in promoting positive peer relations. Some social skill trainings are needed for children to react appropriately in peer relations and get along with their peers. In addition, there is a need for differentiation of the intervention programs by participants' roles in bullying situations and gender of children. Moreover, a longitudinal research is required to enhance the understanding of developmental changes in peer relations.

The purpose of this study was to investigate the living environment design of orphanage based on universal design. The 3 orphanages which were rebuilded recently was selected and evaluated by checklists. The checklists which are based on 'Universal Design Principles' are consist of 120 items. The major results are summarized as follows: 1) The items related to safety were insufficient such as separation of pedestrian passage, rounded edge. 2) The items related to accessibility were high grade such as width of corridor, curb height. 3) Private zones for sleep, study and storage are needed more and living room is needed more furnitures for activities to increase friendship in the family of orphanage. The results will be expected to make contributions to developing orphanage environment design based on universal design, to understanding the nature of universal design paradigm.

Efficient plant regeneration has been achieved via organogenesis in the red pepper plant (Capsicum annum L.). Shoots were induced from seed explants of cultivar 'Friendship' on Murashige and Skoog's (MS) basal medium supplemetned with; NAA or IAA, and BAP or zeatin. Seed explants on the medium supplemented with 0.1-0.3 mg/L IAA and 2-5 mg/L zeatin for 2 weeks vigorously formed normal shoots in more than 90% of the explants. When these were transferred to MS medium containing 0.5-1.0 mg/L GA, 90-100% of the shoots have elongated within 1-2 weeks. The elongated shoots rooted in media supplemented with 0.3 mg/L NAA. It was revealed that this method is very rapid and efficient regeneration system for red pepper and regenerated plants can be obtained after only 5-6 weeks of culture.

TCA(Total Cost Assessment) can be defined by a tool to evaluate actual profit about investment. Also, It can be used by method to make more reasonable decision-making in business. Enforcement of 'direct payment system' for environment friendship farmhouse of government is spreading recent times. But, it is true that it is no definite standard about appropriation of disbursement amount of money. TCA method can be utilized usefully for solution of these problem. Also, It will help to decide price grasping invisible cost and environment cost. Therefore, We tried that may can apply TCA theory in farmhouse class, and attempted economic performance estimation which use this. This study introduces TCA theory and developed applicable expense list in agriculture field. Also, We applied TCA theory to farmhouse. This theories referenced domestic and th6 foreign countries, connection literature. But, It handled part about invisible cost and social cost etc..
