H. S. KIM, H. J. YOON, J. S. RYU, T. S. KIM. The Three Dimensional Analysis of the Upper Body's Segments of the Elderly during Walking. 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.

Backgrounds 3,4-Dichloroaniline (3,4-DCA) is a transformation product of herbicides that is commonly used as a reference in developmental toxicity studies (OECD TG 236) (Bonnet et al. in Environ Toxicol 22:78–91, 2007). However, the mechanisms underlying 3,4-DCA-induced hepatotoxicity are not well known. Methods We exposed zebrafish larvae at 72 hpf to 3,4-DCA for 3 days and observed lipid accumulation in liver treated with 10-μM 3,4-DCA using oil red O staining. Subsequently, we performed qRT-PCR analysis to determine the genes involved in the observed lipid accumulation. Results We found that genes related to lipogenesis (srebp1, pparγ, lipin1, and scd1) and ER stress (bip, atf4, ddit3, dnajc3, and edem1) were significantly upregulated. In addition, we found that ROS generation increased in the larvae treated with 10-μM 3,4-DCA. Moreover, glutathione-S-transferase activity in these larvae was increased by 3,4-DCA in a dose-dependent manner, and the expression of the inflammation marker il-1β increased. Conclusion Our results indicated that exposure to 3,4-DCA induced fatty liver in zebrafish larvae and that this, in association with additional factors such as ER stress response, can promote liver damage. We accordingly suggest that 3,4-DCA could be used to induce fatty liver in zebrafish larvae.

In the history of Chinese women, the Ming Dynasty is a very important era. It was not until then that Chinese people changed their view to support education for women, and the number of educated women increased. In fact, there were a few outstanding individual female writers before the Ming Dynasty; however, in the Ming Dynasty, female writers corresponded with each other and created their own literary works through group activities. This was the reason why female social activities took place actively during the Ming Dynasty. However, the number of those women was still small, and the Ming Dynasty was an era when most women were repressed. Under such circumstances, Xu De Ying was a woman whose writing was distinctive from that of other female writers. She criticized male politics through her criticism of the past, and raised her voice to the world with no hesitation. She pushed beyond the limitations of the women’s quarters, and we can discover her views on trans-boundaries throughout her works.

Objectives : The protective effects of estrogen against the development of schizophrenia have been investigated in various perspectives, Previous studies showed patients with earlier age of menarche had later onset of schizophrenia and less frequent admissions. This study was performed to evaluate the effect of the age of menarche on subsequent courses including hospitalizations, suicidal attempts, Physical harm to others, and psychotic symptoms in women with schizophrenia. Methods : Self-report menarche age, onset of psychotic symptoms, and clinical status were collected in a sample of 108 Premenopausal women with the diagnosis of schizophrenia. Results : There was significant correlation between the age of menarche and the frequency of admissions (r=.321, p=.006). Also, Patients with history of physical harms to others showed later age of menarche than those without (t=2.025, df=106, p=.045). Conclusion : In women with schizophrenia, the age of onset of menarche affects subsequent courses indicated by frequency of admissions and violent behaviors. It is suggested that identifying the age of menarche might be helpful to predict the courses in women with schizophrenia. Further investigations regarding the relationship between estrogen and the courses of Schizophrenia in women are needed.

The purpose of this study was to analyze the smoke eliminating performance of an arcade-type conventional market. In this study, the effect of the openings for the ventilation about the smoke eliminating performance was analyzed. For the fire simulation, the air flow caused by high-buoyance effect should be considered. CFD(Computational Fluid Dynamics) method and compressible k-ε model was used in this study. The indoor temperature and the smoke concentration could be lowered by the openings of the arcade.

To activate traditional markets under deterioration, Korean government have carried out the environmental renewal policy of the traditional market including the induction of arcades. The purpose of this study was to provide the basic information on the design standard of arcade in the traditional markets by 1) analyzing the present condition and the environmental renewal policy of traditional market and grasping the tendency of renewal policy, 2) classifying the street markets into 5 types and finding the street market type that often applied the arcade and 3) selecting two traditional markets that had arcades and investigating the actual condition by the questionnaire to merchants. As a result of the study, the arcades will be introduced for improving the environment of 11 traditional markets that have the streets(width 6m·12m) and many 2-story buildings. And the merchants thought fire safety problem and thermal environment to be important.

Objectives : The purpose of this study was to evaluate the relationship betseen attachment style and somatization in patients with somatoform disorder. Methods : Data was collected by self-report questionnaires. 134 normal subjects and 30 patients with somatoform disorder were enrolled in this study. All subjects completed a psychometric assessment that consisted the Revised Adults Attachment Scale(RAAS), Inventory of Parent and Peer Attachment (IPPA), Sungshin Self-concept Inventory (SSCI), and SCL-90-R. Results : 1) Somatoform patients showed more anxious attachment style than normal control. 2) Anxious attachments were combined with mistrust of their parents, emotional instability, and interpersonal mistrust which may play a significant portion of variance in somatization. Conclusion : We found that patients with somatoform disorder had more anxious attachment style than normal subjects. Insecure attachment patterns may significantly explain the phenomenon of somatization.
