  • The purpose of this study was to investigate the phenomenon of son preference and the related factors among married women in Metro Manila Philippines and to compare between Filipino women and Chinese-Filipino women in many respects. Local schools were contacted for recruitment of participants (n=206) The results showed that more than a half of the respondents(54.5%) preferred a son for the first child. On the other hand almost a half(44.7%) preferred a daughter for the second child. It is interesting that almost a third of married women showed an equal preference between a son and a daughter for the first child (34.2%) and the second child (31.2%) The results of multiple regression analysis revealed that son preference was most strongly related to women's patriarchal attitude and orientation and secondly to a strong son preference for the first child. Two groups of women Filipino and Chinese-Filipino were compared in the level of parental support and expectation for sons and d ughters perception of women's position in family and society patriarchal attitudes and orientation sex preference for the first and the second child reasons of son preference and demographic characteristics. It was found that filipino women tended to prefer a daughter for the second child much more and to perceive women's position much higher than Chinese-Filipino women. Filipino mothers showed an equal level of support and expectations for sons and daughters much more than Chinese groups. For the reasons of son preference it was notable that Filipino women tended to rely on sons in old age much more than Filipino counterparts. Based on the findings of this study three factors were found strong enough to drawour attention. Daughter preference high position of women and equal support for sons and daughters appeared to be closely related in a meaningful way. Future studies need to focus on the relationships among three factors in depth Three factors suggest some important direction tha a strong son preference country like Korea need to head forward in a near future.

  • The purpose of this study was to examine the effect of individual and interpersonal variables on early childhood teachers' efficacy of problem behavior guidance. Individual variables consisted of teachers' socio-demographic characteristics, experience of training course on problem behavior guidance and warm-hearted attitude. Interpersonal variables consisted of intimacy with colleagues, support from the principal of a kindergarten, parental partnerships. Subjects were 122 early childhood teachers in Busan. Major findings were as follows. There were significant differences in teachers' efficacy of problem behavior guidance with respect to teachers' age, teaching experience, position, marriage status, experience of training course on problem behavior guidance, warm-hearted attitude, intimacy with colleagues, and support from the principal of a kindergarten. In other words, a higher level of teachers' efficacy of problem behavior guidance was shown in the teachers who were older, highly experienced, or in higher positions. In addition, teachers who were married, had completed a training course on problem behavior guidance, had a higher warm-hearted attitude, had a intimacy with colleagues, or had a support from the principal of a kindergarten were found to have higher efficacy of problem behavior guidance. As results of examining relative effects of individual and interpersonal variables on efficacy of problem behavior guidance, the influential variables are teaching experience, warm-hearted attitude, support from the principal of a kindergarten, and position in that order.

  • The levels of psychosocial stresses of dental hygienist were analyzed to reveal the various factors related to them. The self-administered questionnaires were performed, to 276 dental hygienist in Daejeon City. Univariate analysis and multiple regression were performed with survey results, in which a degree of psychosocial stress was dependent variable and others were independent variable. 1. In terms of various levels of psychosocial stress according to the higher level of stress was found in the group of lower age, unmarried, and without spare times for hobby activities, the group with shorter-term job career, lower salary, and stress was found in the group who think that their job is considered as low position or their job is not high position in society or their prospect about job is discouraging, the group without regularly exercise, without regularly eating habits, in the group with higher level of job demand, lower job autonomy, and lower social support from colleagues in work than their respective counterparts. 2. Concerning correlation between psychosocial stress and various factors, while level of stress was negatively correlated with age, job career, salary, socioeconomic status of oneself, socioeconomic status of dental hygienist, future status of dental hygienist, job autonomy, social support from superiors, social support from colleagues, social support, but it was positively correlated with job demand. 3. Multiple regression revealed that the factors which influence on psychosocial stress included hobby activities, sleeping hours, job demand, which has explanatory powers of 29.9%. Therefore, to reduce of stress of dental hygienists, it is required to develop an effective strategy that institutional support for improvement of job environments and research for them be revitalized.

  • Purpose: The purpose of this study was to investigate the effects of a task-oriented upper arm exercise performed in a sitting position on either an unstable support surface or a stable support surface for children with cerebral palsy. Methods: We prospectively evaluated 18 children with cerebral palsy. Eight subjects were randomly assigned to each of the stable and unstable support surface groups. We performed the upper arm exercise three times a week for 6 weeks. To confirm the effects of the intervention, the berg balance scale test, modified functional reaching test (MFRT), timed up and go test (TUG), and Jebsen-Taylor hand function test were conducted before and after the study. Results: Significant differences were observed in MFRT and TUG between the experimental and control groups (p<0.05). In the Jebsen-Taylor hand function test, there were significant differences between the groups for the items picking up small objects, stacking checkers, lifting large light objects, and lifting large heavy objects (p<0.05), but not for writing and stimulation of feeding. Significant differences were observed between the groups in items of card turning, lifting large light objects, and lifting heavy objects. Conclusion: The purpose of this study was to evaluate the effectiveness of a task-oriented upper extremity exercise program for dynamic balance and hand function performed in a sitting position with either stable or unstable support by cerebral palsy patients. There were improvements in the two groups, but performing the exercise while sitting on an unstable support surface had a greater effect on dynamic balance and hand function than exercise while sitting on a stable supporting surface. The results of this study can be used to improve the daily lives of cerebral palsy patients.

  • The body to achieve an interaction that are connected to each other. Foot of which plays an important role in motor activity. Insole that has been recently used, have a dynamic functional elements. In particular, support of Arch plays a very important role in terms of a motor function of the human body as a whole. It is possible to predict the proper support Arch with insole, the overall structure of the body there can affect the balance. In this study, by applying the insole which supports the Longitudinal arch and Transverse arch, you are trying to assess the interaction of balance and the body's ability. To target the 20 there is no problem in the sense of balance, college student, and changes were observed by measuring the Center of Position area and distance through the Biorescue device worn before and after led by Arch support. As a result, I showed improved results significantly discount rate after wearing in the Center of Position area and distance to assess the balance ability. Therefore, the correction insole function is to support the Longitudinal arch and Transverse arch to an important role in the foot. It may be that it has a functional element for improving the balance of the function of preventing collapse of the arch during walking, to disperse the weight of the entire foot, us reduce fatigue in the end.

  • PURPOSE: This study investigated the relationship among hip adduction angle, tibial rotation, and ITB length during an Ober test to determine the most appropriate position for performing the test. METHODS: The study included thirty-nine asymptomatic participants (23 males, 16 females). Their hip adduction angles were measured using the Ober test during three tibial rotation conditions (internal tibial rotation, external rotation, and neutral position). ITB length was calculated by measuring the position of the patella to lateral femoral condyle using ultrasonography (patella-condyle distance; PCD). RESULTS: The relationship among hip adduction angle, tibial rotation, and ITB length was analyzed under the three conditions using the Pearson correlation. The hip adduction angle of the internal tibial rotation, the external rotation, and the neutral position were significantly related to ITB length. Moreover, the hip adduction angle measured during the internal tibial rotation had the highest correlation with ITB length among the three conditions (r=.58, p<.001). CONCLUSION: Internal tibial rotation caused by the Ober test led to increased iliotibial band (ITB) tension and a decreased adduction angle. These findings support that tibial rotation influences the flexibility of ITB. Therefore, therapists should consider the position of the internal tibial rotation when taking measurements using an Ober test.

  • This research proposed management plan of internal lecturer who is in charge of job training of researchers working in administrative, researching and developing institutes or public institutions related to information security. The education and training department of the government or public institutions selects and manages lecturers in member of the staff. We applied to the management plan of internal lecturers who are in charge of information security job training by analyzing the way in which internal lecturers are operated by public organizations or corporations. We propose the management plan of internal lecturer according to the position, because the institute of information security is applying the researcher 's position(rank) system. By the proposed circulation management plan by the position, the internal lecturer position is determined according to the position of the employees to be trained and the internal lecturer is selected and operated only at the same position. The proposed management plan includes internal lecturer selection, responsibilities and duties, education, evaluation, and training support.
