Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 1-15, 2004. The purpose of this study was to investigate the kinematic variables of the upper part of the body for 8 elderly men during walking. For this study, kinematic data were collected using a six-camera (240Hz) Qualisys ProReflex system. The room coordinate system was right-handed and fixed in space, with righted orthogonal segment coordinate systems defined for the head, trunk, and pelvis. Based on a rigid body model, reflective marker triads were attached on the 3 segments. Three-dimensional Cartesian coordinates for each marker were determined at the time of recording using a nonlinear transformation(NLT) technique with ProReflex software (Qualisys, Inc.). Coordinate data were low-pass filtered using a fourth-order Butterworth with cutoff frequency of 6Hz. Three-dimensional angles of the head, trunk, and pelvis segment were determined using a Cardan method. On the basis of each segment angle, angle-angle plot used to estimated the movement coordinations between segments. The conclusions were as follows; (1) During the support phase of walking, the elderly people generally kept their head the flexional and abductional posture. Particularly, the elderly displayed little internal/external rotation. (2) The elderly people showed extensional and external rotation postures in the trunk movement. Particularly, It showed the change from adduction into abduction at the heel contact event of the stance phase. (3) The elderly people showed almost same pelvis movement from the flexion into extension, from the abduction into adduction, and from internal rotation into external rotation at the mid stance and toe off of the stance phase.

Korean English Teacher's Disempowerment in English-only Classes

Hwang, Sung-Sam, SeD, Hyo-Sun, Kim, Tae-Young. 2010. Korean English Teacher's Disempowerment in English-only Classes: A Case Study Focusing on Korea-specific Cultural Aspects. The Sociolinguistic journal of Korea 18(1). In this case study, we have focused on the disempowerment of a Korean English teacher (KET) in English-only classrooms. Six English as a foreign language (EFL) classrooms in a Korean high school were observed and analyzed by using interpretive discourse analysis. Out of the six classes, three representative classrooms were both video- and audio-taped. The results show that the English-only classes could weaken the KETs' power via three mechanisms: (a) calling the KETs' last name for choral greetings at the beginning of the class, (b) students' group solidarity and peer pressure between classmates, and (c) the students' excessively collaborative approach to peer assistance. It is argued that the exclusive English-only instruction disempowers the KETs' status and dismantles their vocational identity. In order to remedy the current situation, within a scaffolding supported by the eclectic use of first language where necessary for effective class management, KETs are empowered and overcome constraints imposed by the limited L2 oral competence of some non-native English teachers.

The study was conducted to evaluate the difference of life style, subjective symptoms and health cognition depending on the Sasang Constitution in the industrial workers. The results were as follows ; Constitutional distribution among exposed group were Tae-eum In(38.4%), So-eum In(35.2%), and So-yang In(26.4%) and it was turned out that Tae-eum In took a higher portion of Sasang constitution than other constitutions in technician workers. 'Exercise' and 'Obesity' were found most in Tae-eum In, In So-eum In there were many 'Normal' weight and 'Having digestive disorders' were found most in So-eum In. There were no significant difference in the health cognition among the constitutions. The closer to 'normal' weight, the higher prevalence in 'having' concern about health condition and the more 'normal' condition in sleeping, the higher prevalence of 'having' self-confident in present health.

〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

In this paper, we present a study of the effect of prefetching of pages in the virtual memory subsystem of the operating system. As disk accesses are increasingly becoming a bottleneck of a computer system it is essential that this bottleneck be alleviated. Prefetching of pages in one such approach. Using an algorithm proposed for buffer caching, we modify the virtual memory subsystem of the FreeBSD operating system kernel so that prefetching may be achieved in an effective manner. To validate the effect of prefetching we run experiments using the original operating system and the modified operating system. The experiments are conducted using matrix calculations and by running a I/O intensive benchmark. Results show that the modified kernel provides more efficient execution in terms of actually reducing the number of page faults as well as the real execution time. However, the experiments also show that the bookkeeping overhead induced by the modification increases the system overhead slightly.

As public facilities, public parking buildings are built with tremendous resource investments socio-nationally, and its outcomes affect general public's interests, much more near environments. Public parking building projects have been implemented focusing on how its initial costs could be economical. With literature reviews and expert interviews, elements affecting the construction type of public parking buildings were selected. The comprehensive constructability evaluation process which could be practical in the field is proposed through the classification of evaluation criteria influencing t#e constructability of public parking buildings and sequential evaluation process which modified the analytic hierarchical process. AHP was used as a basis of comprehensive constructability evaluation system, and vector nomalization and linear transformation in multi-criteria decision making technique were applied to each evaluation attributes to select the optimal alternative of public parking buildings.

SummaryThe Study is the attempt to seach for the investment allocation criteria and the fund mobilization measures with regard to the effective implementation of the Cheju Derelopment Plan. Previously the Cheju Development Plan presented the investment amount and the fund mobilization measures only for a certain sector thereby lacking not only the systemetic approach for the effective funding but the investment allocation to guarrantee the feasibility of the plan. This study focuses on the analysis of the investment alloction and the available fund for the Cheju Development Plan and campares the planned amounts with the invested amounts by major sectors.
