The present study was performed to analyze the gene expressions of pituitary adenylate cyclase-activating polypeptide(PACAP) and its receptor in the rat uterus, a candidate for novel extrahypothalamic source and target. The PACAP cDNA fragments corresponding to the common exon region which is found in both the rat hypothalamus and testis were produced from all tissue samples including the rat uterus by reverse transcriptionpolymerase chain reaction (RT-PCR). No PCR product was amplified from the rat hypothalamic, pituitary, ovarian and uterine samples when the 5' primer corresponding to the testis-specific exon 1 region was used, while the predicted size of product was detected from the testis sample. RT-PCR using the uterine RNA and specific primers for the PACAP receptor yielded products with predicted sizes. Transcripts for the rat uterine PACAP receptor were identified as type I isoforms with hip-hop and hip- or hop-type inserts. After pregnant mare's serum gonadotropin (15 IU) treatment of immature rats (day 25), the level of PACAP mRNA was increased in 24 h and 48 h group, and was declined to the lowest in 72 h group. The present study shows the presence of transcripts for PACAP and its receptor isoform in the rat uterus. These finding ssuggest that the uterine PACAP ight act as a novel autocrine and/or paracrine factor via its specific receptors on the reglulation of rat uterine function and physiology during the reproductive cycle.

Purpose: The purpose of this study is to evaluate diagnosis and treatment of acetabular labral tears in sports injuries. Materials and Methods: From March 1995 to January 2000, We treated 15 patients with acetabular labral tear by sports injuries. There were 6 men and 9 women. Mean age was 41 years old. Running injuries are 5 cases, fighting 3, aerobic exercise 3, swimming 2, climbing 1, bicycle 1. For conservative treatment, we performed medication and observation at least for 1 year. For the patients with arthroscopic surgery, we performed Harris Hip Score (pain and function) preoperatively and postoperatively at 6, 12 months, and evaluated patient’s pain by JOA pain scoring system and postoperative subjective satisfaction. Results: The mean score of HHS improved 15 points with conservative treatments and 32 points with hip arthroscopy. In 4 cases of conservative treatment, there was 1 scale improvement of JOA pain scoring system. In arthroscopic partial labrectomy, all cases were improved to more than 2 scale. Conclusion: We considered that acetabular labral tears occurred associated with sports injuries. So it is important to be interested in enthusiastic diagnosis and appropriate treatment for hip pain caused by sports injuries, especially about acetabular labral tears.

Total hip arthroplasty (THA) is a successful surgical treatment for both patients with chronical lameness and dogs who are nonresponsive to medical treatments, providing excellent joint function for returning dogs to the normal gait in 80% to 98% of hip dysplasia (HD) patients. The THA surgical implant system manufactured by BioMedtrix and Kyon are today widely accepted. When comparing the BioMedtrix biological fixation (BFX) system to the BioMedtrix cemented fixation (CFX) system, the many advantages of BFX, which include longer potential implant life, decreased risk of postoperative or later infection, and better implant stability, become evident. However, BFX implies a greater risk of femoral fracture during reaming and requires a more precise surgical technique to achieve good implant fit, given the press-fit nature of cementless THA. The purposes of this study are to both describe the mistakes and complications during stem implantation for beginner surgeons with both the BFX and the CFX systems and to document the initial result of 12 implantations in canine cadavers. Given the detailed evaluations of 3 specialists, who are Diplomate American College of Veterinary Surgeons (DACVS), only 3 of 11 stems were appropriately sized. Specifically, 6 stems were anteverted rather than being retroverted; further, although 7 stems were coaxial with the femoral long axis in the frontal plane, the other stems were in the varus at the frontal plane, with the proximal medial stem adjacent to the medial femoral cortex. Moderate angulation from the cranial to the caudal directions was found in 4 cases in the sagittal plane. Additionally, 1 case of femoral fissure and 1 case of perforated femoral cortex were reported. It is not easy for surgeons performing cementless THA for the first time to achieve a good result, even though they completed an educational course about it and given that catastrophic complications often occurred during early surgical clinical cases. Therefore, ex-vivo studies are sincerely required to get an expertise by rehearsing the preparation of the femoral envelop in isolated bones. Further studies should be conducted to achieve both highly accurate implant size and correct orientation during the preoperative planning. Additionally, surgeons' learning curve should be examined in future investigations.

The work-man's Uniform should be coincident with the image of his firm and accounted of the function according s its purpose. We made questions to 404 workers at 8firm in our country through the questionnaire papers to know about a work-man's uniform and researched whether the satisfactory in wearing his uniform had relation with his type of business, grade, carrier, age, marriage, and monthly income. The results of this study is as follows; 1. In the case of wearing the uniform many workers answered they always wore their uniform in the firm. It was shown that the office workers wore their uniform much more than workers in the production department. The longer the time working, the older age, the lower grade of school career are, he more workers wear. the order of the importance for he uniform was the function, the symbol, the originality, and the fashion. The longer their career in the firm was, the more important the function of their uniform was. 2. The order of dirty pat in taking care of the uniform was cuffs, color, the front of part in an upper garment and below the knee, the hip in pants It was very easy for the workers in the experts, or administrators and office workers than others to be dirty in the cuffs part of the uniform. Worn part of the uniform showed highest cuffs in an upper garment and a zipper in pants. The order of cleaning the uniform was washing by water, no ironing, and cleaning in their house.

An underwear originated from when a human lost his purity and recognized his situation. But, it could not be sure when underwear and an outer garment were classified according to a function. An underwear has been used for a decorative and mental function, as well as a practical one. Also, it is the most fundamental medium to understand a human and a period. However, many studies on outer garments not an underwear have been done till now Therefore, this study was done to be arranged and analyzed materials scattered in order to give a correct understanding of an underwear as a clothes. The data were based on the existing fashion pamphlets, fashion magazines and other materials. The main results were as follows; Female's contemporary underwear was classified into Hosiery, Foundation and Lingerie. The Hosiery was again classified into chemise, combination, drawers and brief. The most typical hosiery was a chemise for a health and hygiene, and the drawers was adhered closely to a body. The Foundation which had a function to be well shaped was classified into Brassiere, Girdle, All in one, Body suit, Corset, Waist nipper and Garter belt. A typical contemporary foundation was a brassiere and a girdle. A brassiere had a role to support the breast up and A girdle compensate a hip area. The Lingerie which made body silhouette be vivid was classified into Slip, Panty, Wintum, Linge, Home lingerie, and so on. A slip, a panty and a lingo were typical lingeries. A slip made an outer garment be well-formed.

The dynamic responses of human standing postural control were investigated when subjects were exposed to long-term horizontal vibration. It was hypothesized that the motion of standing posture complexity mainly occurs in the mid-sagittal plane. The motor-driven support platform was designed as a source of vibration. The AC Servo-controlled motors produced anterior/posterior (AP) motion. The platform acceleration and the trunk angular velocity were used as the input and the output of the system, respectively. A method was proposed to identify the complexity of the standing posture dynamics. That is, during AP platform motion, the subject's knee, hip and neck were tightly constrained by fixing assembly, so the lower extremity, trunk and head of the subject's body were individually immovable. Through this method, it was assumed that the ankle joint rotation mainly contributed to maintaining their body balance. Four subjects took part in this study. During the experiment, the random vibration was generated at a magnitude of $0.44m/s^2$, and the duration of each trial was 40 seconds. Measured data were estimated by the coherence function and the frequency response function for analyzing the dynamic behavior of standing control over a frequency range from 0.2 to 3 Hz. Significant coherence values were found above 0.5 Hz. The estimation of frequency response function revealed the dominant resonance frequencies between 0.60 Hz and 0.68 Hz. On the basis of our results illustrated here, the linear model of standing postural control was further concluded.

In this paper we present our work on the parameterized construction of virtual drivers' reach motion to seat belt, by using motion capture data. A user can generate a new reach motion by controlling a number of parameters. We approach the problem by using multiple sets of example reach motions and learning the relation between the labeling parameters and the motion data. The work is composed of three tasks. First, we construct a motion database using multiple sets of labeled motion clips obtained by using a motion capture device. This involves removing the redundancy of each motion clip by using PCA (Principal Component Analysis), and establishing temporal correspondence among different motion clips by automatic segmentation and piecewise time warping of each clip. Next, we compute motion blending functions by learning the relation between labeling parameters (age, hip base point (HBP), and height) and the motion parameters as represented by a set of PC coefficients. During runtime, on-line motion synthesis is accomplished by evaluating the motion blending function from the user-supplied control parameters.
