An emotion inference task was used to investigate children's cognitive cuing by age, cue type, and situation-emotion fit. Subjects were 41 of 3-, and 5-year-old children from two different day-care centers in Seoul and Kyonggi province. Each child was individually interviewed with pictorial tasks. 5-year-old children demonstrated more cuing, thinking, and application responses than 3-year-old children. Particularly, they showed more situation and thinking responses in situation-emotion match than in situation-emotion mismatch. 3-year-old children showed more past-oriented responses than 5-year-old children. In the interpersonal cue story, there were more situation, past-oriented and thinking responses than in the interobjective ones. The interpersonal cue story produced more situation responses in situation-emotion match than in situation-emotion mismatch.

The aim of this study was to find out the differences of biomechanical factors from touching down the vaulting board to landing when techniques of 1/1Turn, stretched, and Tucked were performed on the old vaulting horse and on the new vaulting table. Three national representative men gymnasts were sampled for this study. Three dimension motion analyses by means of six Sony PD-150 video cameras with the velocity of 60 fps were used. As a result of analyzing the kinetic data from two kind of vaulting table, the following conclusions were made. 1. There was not significant differences of angular momentum between the old and the new vaulting table in all three techniques except the phase of stepping on the vaulting board and contacting the vaulting horse in the Tucked technique. IN the two phases above, the angular momentum in the new vaulting table was greater than that of the old vaulting horse. 2. There were few significant differences between the old and the new vaulting horses in the horizontal and vertical reaction force according to techniques when stepping was performed. However, it appeared tendency that the horizontal and vertical reaction force in the new vaulting table was a little greater than that of the old vaulting horse when the 1/1Turn, the Stretched and the Tucked were performed.

Three national representative men gymnasts were sampled for this study. Three dimension motion analyses by means of six Sony PD-150 video cameras with the velocity of 60 fps were used As a result of analyzing the kinematic data from two kind of vaulting table, the following conclusions were made. 1. The performing time from taking off the vaulting horse to landing(phase 4) in the 1/1 Turn technique on the new vaulting table was significantly longer than that of the old vaulting horse, while the time from contacting to taking off the vaulting horse on the new vaulting table was shorter than that of the old vaulting horse in both and the Tucked techniques. 2. The vertical release COG velocity was faster on the new vaulting table compare to the old vaulting horse in the all kind technique. However the horizontal release COG velocity of the 1/1 Turn technique was faster a little in the old vaulting horse compare to the new vaulting table.

Ten Australian Stock Horses colts (five yearling and five 3-year old colts) of which 2 yearlings and 2 three year old colts served as control animals while 3 yearlings and 3 three year old colts received two GnRH immunizations within 4 weeks interval were used in this study. By the 5th to 6th week after immunization, the GnRH antibody titres in the plasma rose above 1:1000 and attained peak levels of 1:6500 by the 8th week and gradually declined to about 1:3000 by the 10th week in both the age groups. The testosterone and androstenedione concentrations of the control colts in both age groups were significantly greater (p<0.05) than that of the vaccinated groups. During the immunosuppression period, the vaccinated colts behaved like geldings. Semen could not be collected from 2 of the 3 three-year old vaccinated colts. The testicular dimensions, testicular weight, parenchymal weight, seminiferous tubule volumes, interstitial space volumes, Leydig cell volume, seminiferous tubule % of the control colts were significantly greater than those of the vaccinated colts in both the age groups. The 3-year old control colts had a significantly (p<0.05) greater % of Leydig cells than the control and vaccinated 1-year old colts. There was arrest of spermatogenesis with complete absence of sperm in the testes of the vaccinated colts while there was various stages of spermatogenesis in those of the control colts. Morphometric analysis demonstrated that the 3-year old colts had significantly (p<0.05) greater DSP/gm of testis and DSP/testis than those of the 1-year old control colts. This study elucidated that the GnRH immunization could suppress the testicular function of the 3-year old and yearling colts.

The purpose of this study was to investigate the influences of household income, education needs, private education expenses and expenditures of preparation for old age for mothers of school-aged children and to discover the causal relationships among these variables. The subjects in this study were gathered from among 393 mothers living in Daegu with school-aged children from 8 to 19 years old and with wage-earner husbands. The research tool was a questionnaires which addressed the general characteristics of the subjects, household income, the scale of education needs, the scale of private education expenditures, the scale of perceived burden of private education, and the scale of expenditures of preparation for old age. In order to analyze the study data, factor analysis, and regression analysis using SPSS were used, and structural path analysis using AMOS was used. The main results of this study were as follow: First, the greater the household income, the greater the education needs. Second, household income and education needs had no significant influences on private education expenditures. Third, education needs and private education expenditures turned out to have significant effects on the perceived burden of private education expenditures. Fourth, expenditures of preparation for old age among mothers of school-aged children was influenced by the education needs, private education expenditures and perceived burden of private education expenditures. The household income of mothers of school-aged children had no significant influence on private education expenditures. Finally, education needs, private education expenditures and perceived burden of private education expenditures for mothers of school-aged children had a direct effect on the expenditures of preparations for old age. On the other hand, in mediating education needs, household income of these mothers had an indirect effect on expenditures of preparations for old age. The perceived burden of private education expenditures turned out to have the biggest total effect on the preparations for old age of mothers with school-aged children.

While Korean traditional culture considers it necessary that children support their parents, a new trend of silver support is expanding by the recent social change, the increase of women's working, and the reluctance to support the old people. However, the number of silver welfare facilities in Korea is short for the demand with limited selections of them. Based on the situation, the following results of the study what kind of policies Korea service for the old people in the USA where early stepped into the aging society: 1. provide specific and proper social-supporting service and facilities with charge or free for the old people to be able to select one of them, according to economic, physical and psychological situation of the old people; rather to prepare service and facilities for all the old people. 2. increasing community service support for the home-staying old people 3. the development of support program for the family of the old 4. the improvement of housing environment for the home-staying senior 5. prepare the housing alternatives for the senior would be home-like environment.

This study intends to recognize the old as an independent consumer, and to examine the behavioral characteristics of the old through literature review. This study also tries to suggest the direction of study on the elderly consumers' behavior. It has been generally accepted that the elderly consumers are highly constricted in purchase behavior or in information process capacity by the decline of biological competence. But according to the literature review, this general viewpoint does not reflect the reality. The literatures say that the old consumers do not so much differ from the non-old consumers in behavioral characteristics. They rather seem to be more active consumers. Nevertheless, what they claim could be a fallacy due to the overspecialization of sample. And another direction of future research is to change the age boundary of the old. The existing studies were largely based on the distinction between the old and the non-old by the age of 60 or 65. It is possible that behavioral difference is diffused by the common purchasing patterns of cohort around the age of 60 or 65. Accordingly it would be a good attempt to widen the range of age group more than 10 years.

Purpose: The purpose of this study was to compare the clinical and radiographic features of temporomandibular joint (TMJ) osteoarthritis (OA) between adolescents and middle-old aged patients. Methods: The subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital and were diagnosed with TMJ OA by clinical exam, X-ray and cone-beam computed tomography (CBCT) from 2010 to 2011. We investigated 93 adolescent patients (12-19 years) and 53 middle-old aged (>45 years) patients who observed the erosive bony changes in TMJ. CBCT scans were retaken at intervals at an average of 8 months. Results: The adolescent patients showed unilateral degenerative changes more often, and the middle-old aged patients showed degenerative changes more frequently on both sides. The transition of bone changes to the improved group occurred most commonly in both the adolescent and middle-old aged patients. The adolescent patients were more likely to improve than middle-old aged patients. In the adolescent patients, loss of erosion and subjective symptoms occurred in shorter periods than in the middle-old aged patients. In the adolescent patients, the transition of erosion was distributed into proliferative, normal, and shortening in order. In the middle-old aged patients, the transition of erosion was distributed into shortening, proliferative, and normal in order. Conclusions: The clinical and radiographic features of TMJ OA are a significantly different between the adolescent and middle-old aged patients. Moreover, the difference by age of the adaptive and regenerative capacity of TMJ affects the prognosis of TMJ OA and adolescent patients have a better prognosis after treatment.

Objective: The purpose of this study was to analyze the risk factors of the musculoskeletal workload of mid-old-age female caregivers by identifying work postures and subjective symptoms. Method: This study was carried out on a total of 206 subjects 206 mid-old-age caregivers(45~65 years old) from November 2009 to April 2010: 206 mid-old-age caregivers (45~65 years old) at the long-term hospital. A questionnaires survey on general factors and subjective symptoms of subjects was conducted. The risk factors of the musculoskeletal workload evaluation method is based on OWAS, RULA, REBA according to occupation properties. Results: The analysis of the rates of the subjective symptoms showed that 78.6% subjects experience low back pain. The analysis of the work type showed that transfer is the highest rate(36.3%) and position change is the second(18.2%). The analysis of the work postures showed that the thrusted back with twisting position over $20^{\circ}$ is highest rate(37.4%), the bended back forward with twisting position is the second(27.5%). Conclusion: This study suggested that the need of preventive education for caregivers and workload improve. It is hoped that subsequent study on the difference of subjective symptoms between educated caregivers and non educated caregivers will be conducted.

The conservation of collections in muse-ums is an important aspect for our her-itage. The control of museum environment is a vital factor in the preservation of cool-lections. Inappropriate or fluctuating envi-ronmental conditions can cause irreparable damage to works of arts. In this research we investigated the ac-tual conditions of museum environment for old testiles using questionnaire and mea-sured dye fasing of old textiles on exhibi-tion for 2 months in a university museum the major results are as follows: 1. The control of temperature and rela-tive humidity is a vital factors I the preservation of old textiles in museum generally acceptable temperature and rel-ative humidity standards for old textiles are 18-23$^{\circ}C$ and 50-65% R. H and light level for textiles on exhibition should be limited to 30-50 lux. 2, In university museums the limate control system in exhibition and storage area is in an early stage. Therefore to minimize the deterioration of old textiles the best method of controlling the envi-ronment is to have centralized climate control system in sorage area as well as in display area. 3. Conservator is needed to maintain collections scientifically. Only professional conservator by combining scientific tech-nical and artistic training has the exper-tise needed to maintain the physical in-tegrity of old textiles. In order to solve the inferior environment of museums the staff should recognize the importance of the condition of exhibition and storage. 4. Old textiles are susceptible to damage by light and associated heat. Dyed textiles which have been exhibited under the light without any UV filter were faded notice-ably within two months of exhibition. Light levels for textiles on exhibition should be limited to 30-50 lux. It is de-sirable to use special light source that can absorb UV. and UV filter is also recom-mended to reduce photodegradation of old textiles.
