One of the controversial issues in English locative inversion (LI) construction( e. g. Under the tree sat a woman) has been the functional status of preverbal PP and postverbal NP, i.e. whether they are a subject, a complement, or filer (topic) Based on the distributional parallelisms between the PP and NP on the one hand and an ordinary subject and filler on the other this paper proposes that the PP has a dual function as a subject and filler, while the NP also has some subject properties that the PP does not have These mixed functional properties are analyzed in the theory of HPSG expecially with the versions recently developed by Sag(1997) Manning and Sag(1999) and Ginzburg and Sag(to appear). This analysis claims that the LI construction needs to satisfy two general, independent constraints head-subject- phrase and head-filler-phrase. This position suggests that the English LI construction is an instance of the peripheral phenomena whose construction specific constraint is inherited from more general core constraints.

The establishment of an optimal and functional condylar position (centric relation) as the therapeutic and diagnostic reference position during occlusal treatment for patients with temporomandibular joint and muscle pain. dysfunction has long been an important subject in dentistry. The objective of this study was to compare the reproducibility md the changes of condylar position in normal group to those in patient group after use of the occlusal biteplane splint. For this study, 11 normal adults who had no symptoms of masticatory dysfunction and 18 patients who had visited at the department of occlusion in dental infirmary of Yonsei University were selected. For each subject three centric relation records were recorded before treatment, after 2 weeks and after symptoms were improved. And the condylar positions in centric relation were measured using articulators and a Vericheck. On the basis of this study, the following results were obtained. 1. In normal group, there was no significant difference of reproducibility in condylar position before and after the use of the occlusal biteplane splint for 2 weeks. 2. In patient group there was significant improvement in the reproducibility of condylar position after treatment (P<0.01). The reproducibility in patient group, however, was less than normal group. (P<0.01) 3. The mean distance of condylar movements was $0.38{\pm}0.22mm$ after 2 weeks in normal group. 4. In patient group, condylar movements were $1.36{\pm}0.70mm$ (P<0.01), significantly different from normal group. (P<0.01) 5. In patient group, the main direction of condylar movements after treatment was toward anterior and superior, preponderance being at superior direction.

Objective: To investigate the effect of performing three different toe touch (TT) task condition on the activities of four different muscles using surface electromyography (sEMG) in healthy young adults. Design: Cross-sectional study. Methods: A total of 20 healthy young adults (6 males, 14 females) voluntarily participated in this study. All subject randomly performed three different TT task conditions as follows: general toe-touch (GTT) task, one side toe touch (TT) task during weight bearing, and one side foward toe touch (FTT) task during weight bearing. The muscle activities of erector spinae (ES), gluteus maximus (GM), hamstring (HAM), tibialis anterior (TA) muscles during the TT task were measured using sEMG. Subject performed each of the three conditions three time in random order and mean values were obtained. Results: With the trunk flexion period, the TT and FTT showed significantly greater muscle activity in the GM, HAM and TA compared to the GTT task (p<0.05). The TT position showed significantly greater HAM muscle activity than the GTT position. The dominant and nondominant ES muscle activity was significantly greater in the FTT compared to the GTT position (p<0.05). The dominant GM, HAM, and TA was significantly greater in the TT and FTT compared to the GTT position (p<0.05). Although the dominant ES was significantly greater in the TT and FTT compared to the GTT position (p<0.05), the dominant GM muscle activity was signifcantly greater in the TT compared with the GTT position (p<0.05). Conclusions: These findings may be applicable within the clinical field for selective trunk and lower extremity muscle activation and basic biomechanics purpose.

Objective: The first aim of this study is to determine the effects of acupuncture on the autonomic nervous system (ANS) via Heart Rate (HR) and Pupil Size (PS), and to compare the effects of acupuncture on the subjects' ANS when they are in a sitting position with the effects when they are in a supine position. Methods: Ten healthy male subjects were randomized to receive either verum acupuncture stimulation in a sitting position (SitV), verum acupuncture stimulation in a supine position (SupV), sham acupuncture stimulation in a sitting position (SitS), and sham acupuncture stimulation in a supine position (SupS). Acupuncture stimulation was applied to Neguan point (PC6) on the forearm. The subject's electrocardiogram (ECG) and pupil size were recorded continuously from 5 min before stimulation to 12 min after stimulation. Results: Verum and sham acupuncture stimulation were found to have reduced heart rate (p<0.01) and to have increased pupil size (p<0.01) in all the subjects. But when the reduction in HR and the increment in PS after verum acupuncture stimulation (both sitting and supine position) were compared with those after sham acupuncture stimulation, it was found that the reduction in HR (74.48 and 73.47 bpm, p<0.063) and the increment of PS (7.32 and, 6.10 mm, p<0.001) after verum acupuncture stimulation were greater than those after sham acupuncture stimulation, and that the corresponding values were statistically significant. In addition, at the baseline, it was found that the subjects had a larger PS and a faster HR in a sitting position than when they did so in a supine position. And then the reduction and increment ratio in the subject's HR and PS when they underwent acupuncture stimulation in a sitting position was significantly different from the reduction and increment in their HR and PS when they underwent the procedure in a supine position-i.e., the reduction ratio in HR was greater when they underwent the procedure in a sitting position, and such reduction ratio was statistically significant (p<0.05). As for the increment in PS, it was greater when the subjects underwent the procedure in a supine position, and such increment was significant (p<0.05). Conclusion: Manual acupuncture stimulation on Neguan point (PC6) has more significant influence on the autonomic nervous system rather than sham acupuncture (tactile stimulation). And the position-induced different states of ANS have different influence on the acupuncture effect.

Purpose. This study was to investigate the degree of refractive error that occurs depending on the measurement location of the subject when performing a refraction test using the automatic refractor. Methods. When performing the auto-refraction test, measurements were taken while increasing the distance between the forehead and the forehead rest, and the measurements were made by tilting the head clockwise and counterclockwise. Results. During the auto-refraction test, significant refractive error occurred when the forehead was not attached to the forehead support or the subject's head was turned clockwise or counterclockwise. Conclusions. When performing a refraction test using an automatic refractor, the examiner will have to pay attention to whether the subject's forehead is in close contact with the forehead rest, and whether the head is tilted.

The purpose of this study was to investigate the relationship between the mandibular positions and the habitual mandibular opening and closing movements in normal subject using the newly developed electric mandibular movement analyzing device(Saphon Visi-Trainer C-II.Tokyo Shizaisha Inc. Tokyo, Japan) One of the cause of the temporomandibular joint dysfunction has been considered abnormal mandibular positions especially the abnormal deviation between intercuspal position from retruded contact position. The subjects in this study were consisted of 55 young adults in 20 decade who had normal occlusion, no prosthodontic restorations and no history of disturbance or pain on temporomandibular joint and masticatory muscles. The results were as follows : 1. The deviations of intercuspal position from retruded contact position were 0.23mm in frontal view and 1.02mm in sagirral view. 2. The larger the deviation of intercuspal position from the retruded contact position, the higher the proportion of uncoincidence of the habitual nandibular closing and opening trajectories was, and the proportion was higher in sagittal view than frontal view, 10mm opening than 5mm opening. 3. Correlation between the deviation of intercuspal position from retruded contact position and uncoincidence rate of the habitual mandibular closing and opening trajectories was higher in frontal view than sagittal view.

The purpose of the study was to investigate the effectiveness of ankle mobilization on neck and shoulder position. One hundred volunteers, aged between 18 and 26 years (mean age 22), were recruited and each subject was divided into four mobilization groups by their body type, which is based on the concept from 'general coordinative manipulation' and a control group. Ankle mobilization was applied based on their body type and no mobilization was applied on those of the control group. The positions of shoulders and neck were measured in comfortable standing posture. All measurements were taken before and after ankle mobilization from each subject in mobilization groups and those of control group was measured twice between ten minutes by a different tester on three different occasions. Twenty subjects were in each group basis of their body type and a control. In the position of neck and shoulder, all subjects regardless group showed significantly changed their neck

The purpose of this study was to determine the effect of head posture and respiratory pattern on muscle activities of sternocleidomastoid (SCM) and scalene during maximal respiration. The seventeen subjects with upper-costal breathing pattern were participated in this study. Surface electromyography was used to measure the muscles activities of SCM and scalene. The volume and velocity of inspiration were monitored by using the spirometer in each subject. Each subject was performed the 3-cycle of respiration in each condition. The mean values of three peak muscle activity in each muscle were used in the data analysis. A2 (head posture: forward head posture: FHP vs. neutral posture) X 2 (breathing pattern: costal vs. diaphragmatic) repeated-measures analysis of variance (ANOVA) was used to compare the normalized muscle activities of the SCM and scalene. The results showed that the muscle activities of SCM and scalene in diaphragmatic breathing were significantly lower than those in costal breathing for each head posture (p<.0125). The muscle activities of SCM in neutral position were lower than those in forward head position during costal breathing (p<.0125). The diaphragmatic breathing in neutral position of head is recommended to decrease the tension of the accessory inspiratory muscles during respiration in neck-pain patients with FHP.

The isometric position of the anterior cruciate ligament was calculated during flexion-extension. Flexion-extension motion data of the knee joint were obtained by Fastrak, a three-dimensional motion measurement system. A subject was seated on a flat table and the tibia sensor position was measured with the femur fixed at the table. A three-dimensional knee model was constructed using a graphic tool to simulate the knee motion. Three surgical positions of the femoral tunnel were selected and the distances between the determined tibial tunnel and each femoral tunnel were calculated. The maximum elongation position was found to be in the ten thirty direction of clock.
