Measurement of magnetic signals generated from electric activity of myocardium provides useful information for the functional diagnosis of heart diseases. Key technical component of the magnetocardiography (MCG) technology is SQUID. To measure MCG signals with high signal-to-noise ratio, sensitive SQUID magnetic field sensors are needed. Present magnetic field sensors based on Nb SQUIDs have field sensitivity good enough to measure most of MCG signals. However, for accurate measurement of fine signal pattern or detection of local atrial fibrillation signals, we may need higher field sensitivity. In addition to field sensitivity, economic aspect of the SQUID system is also important. To simplify the SQUID readout electronics, the output voltage or flux-to-voltage transfer of SQUID should be large enough so that direct measurement of SQUID output can be done using room-temperature preamplifiers. Double relaxation oscillation SQUID (DROS), having about 10 times larger flux-to-voltage transfers than those of DC-SQUIDs, was shown to be a good choice to make the electronics compact. For effective cancellation of external noise inside a thin economic shielded room, first-order axial gradiometer with high balance, simple structure and long-baseline is needed. We developed a technology to make the axial gradiometer compact using direct bonding of superconductive wires between pickup coil and input coil. Conventional insert has mechanical support to hold the gradiometer array, and the dewar neck has equal diameter with the dewar bottom. Boiling of the liquid He can generate mechanical vibrations in the gradiometer array due to mechanical connection structure. Elimination of the mechanical support, and direct mounting of the gradiometer array into the dewar bottom can reduce the dewar neck diameter, resulting in the reduction of liquid He consumption.

Background: The execution of fibular allograft augmentation in unstable proximal humerus fractures (PHFs) was technically demanding. In this study, the authors evaluated the clinical and radiographic outcomes after tricortical iliac allograft (TIA) augmentation in PHFs. Methods: We retrospectively assessed 38 PHF patients treated with locking-plate fixation and TIA augmentation. Insertion of a TIA was indicated when an unstable PHF showed a large cavitary defect and poor medial column support after open reduction, regardless of the presence of medial cortical comminution in preoperative images. Radiographic imaging parameters (humeral head height, HHH; humeral neck-shaft angle, HNSA; head mediolateral offset, HMLO; and status of the union), Constant score, and range of motion were evaluated. Patients were grouped according to whether the medial column support after open reduction was poor or not (groups A and B, respectively); clinical outcomes were compared for all parameters. Results: All fractures healed radiologically (average duration to complete union, 5.8 months). At final evaluation, the average Constant score was 73 points and the mean active forward flexion was $148^{\circ}$. Based on the Paavolainen assessment method, 33 patients had good results and 5 patients showed fair results. The mean loss of reduction was 1.32 mm in HHH and 5.02% in HMLO. None of the parameters evaluated showed a statistically significant difference between the two groups (poor and not poor medial column support). Conclusions: In unstable PHFs, TIA augmentation can provide good clinical and radiological results when there are poor medial column support and a large cavitary defect after open reduction.

Purpose : Granular cell tumour(GCT) is a rare benign tumour that can arise in anywhere throughout the body. Histopathological diagnosis of malignancy is difficult. We report a case of a granular cell tumor which developed on lower lip. Methods : A 58-year-old male had a palpable mass and whitish plaque in the oral mucosa for three months. Results : Under local anasthesia, the tumor was removed through wide excision including normal skin margin. Immediate reconstruction using local flap was done. Pathologic observation showed nests of polygonal cells with abundant granular, eosinophilic cytoplasm and round nuclei. Immunohistopathologic staining showed positive reaction on S-100 protein Conclusion : The results support the hypothesis that granular cell tumor is derived from Schwann cells. We report here on a case of granular cell tumor of lower lip that was successfully treated with radical resection.

The goals of lip reconstruction are to provide oral competence, adequate support for the lower lip, contour restoration, adequate lip sulcus, and adequate oral aperture. The composite radial forearm palmaris longus free flap is thin enough that it can be folded onto itself without a significant increase in bulk. The flap is easy to dissect, the pedicle contains long vessels of large diameter, and the skin is a good color and texture match for the perioral region. Moreover, the vascularized tendon can be used for lower lip reconstruction. This makes the flap ideally suited for total lower lip reconstruction. We experienced the case of total lower lip excision and reconstruction with the radial forearm free flap including palmaris longus tendon, so we reported that case with literature. The patient has a lower lip squamous carcinoma(T3NIM0), and performed a total lower lip excision with right modified radical neck dissection and left extended supraomohyoid neck dissection, and a reconstruction with radial forearm free flap includng palmaris longus tendon. The oral competence and masticatory function were nearly normalized and cosmetical result was very acceptable.

Objective: Poor head and neck support during sleep can exacerbate the neck pain. Based on the ideal sleep posture and pillow suggested by Cyriax, we designed a new cervical pillow and compared the degree of pain reduction, quality of sleep and pillow satisfaction with a low hospital pillow and a high pillow. Method: The newly designed pillow has a built-in pressure-adjustable air bag in the cervical area and provides normal cervical lordotic curve in supine position and maintains cervical and thoracic vertebrae to form a horizontal line in side-lying position. Thiry-four patients with cervical pain used low hospital pillows for the first week of 3-week randomized crossover design study. They were subsequently randomly assigned to use each of the other two pillows for 1-week period. Outcomes were measured using Visual analog scale, Sleep questionaire, a pillow satisfaction scale. Result: Compared with other 2 types of pillow, Subjects using the newly desinged pillow showed much reduced pain intensity, increased duration of sleep and better satisfaction. Conclustion: We desinged a cervical pillow with built-in pressure adjustable air bag and it can significantly reduce pain intensity and improve quality of sleep in patients with cervical pain.

The purpose of this investigation was to examine the influence of head and neck(HN) position in the transverse plane on the static production of elbow extension force in the involved(paretic) upper extremity of patients with hemiparesis. On this study, thirty patients who had experienced a cerebrovascular accident were matched with neurologically intact subjects. Force of static elbow extension was tested with a hand-held dynamometer, twice with the HN rotated toward the paretic side and twice with the HN rotated toward the non-paretic side. Elbow extension force differed significantly with the HN in the two position in patients with hemiparesis but not in normal persons(${\alpha}$=0.05). Results of this study support the conclusion that HN position in the transverse plane influences the production of static elbow extension force on the paretic side in patients with hemiparesis.

Traditionally, wound drainage after thyroid or parathyroid surgery has been widely used to prevent airway obstruction due to accumulation of hematoma or seroma within the paratracheal dead space. Recently, however, the routine use of drains after thyroid or parathyroid surgery has become a matter of controversy. To determine whether the rouine use of drains after thyroid or parathyroid surgery is warranted, a prospective study on the complications after various types of thyroid or parathyroid surgery without wound drains was conducted. Three hunded sixty-six consecutive patients underwent thyroid or parathyorid surgeries by one surgeon from January through December 1994 were included in this study. Of these, only 38 patients (10.4%) required the wound drains. Indications for drainage included the patients with a large dead space(n=9) or wet operative field at the conclusion of surgery(n=11), and patients with radical neck disection(n=18). In the remaining 328 patients(89.6%), the wounds were closed without drains after thyroid lobectomy and isthmusectomy(n=226), bilateral subtotal thyroidectomy(n=21), total or near-total thyroidectomy(n=62), isthmusectomy(n=9) and parathyroid surgery(n=l0). Histologic findings revealed benign tumors in 214(65.2%), carcinoma in 89(27.1%), Graves' disease in 15(4.7%), hyperparathyroidism in 7(2.1%) and parathyroid cyst in 3(0.9%). Among the 328 patients without drain used, wound related complications were seen in only 15 patients(4.6%); 12 patients with seroma and 3 patients with hematoma. All but one complications could be controlled by two or three aspirations, and the remaining one patient required re-exploration. There were no instances of laryngeal nerve palsy or wound infection. The mean length of hospital stay after surgery was 2.8 days with a range of 1 to 11 days. These results support the routine use of drains is not warranted in most thyroid or parathyroid surgeries.

The objectives of this study were to obtain normative data for 45 mother-daughter pairs on spine, femur(neck, ward's triangle, trochanter) and total body BMD (bone mineral density) measured by dual energy X-ray absorptiometry, anthropometric measurement, body composition, biochemical markers, nutrient intakes and energy expenditure, to determin the interrelations of these factors within each group, to measure familial resemblance for each variable. We observed significantly positive correlations between height, weight, head, hip and calf circumferences, tricep, femur and calf skinfold thickness, total lean body mass(=weight-total fat body mass-bone mineral content), protein and fat intakes, Ca index, serum total protein and albumin of monter-daughter pairs(p<.05-p<.001). Among mothers, age, osteocalcin, higher, weight, Ca and energy intakes were predictors of BMDs. Among daughters, weight and energy intake were predictors of BMDs. The BMD in lumbar spine(r=.48, p<.01), femoral neck(r=.38, p<.05), ward's triangle(r=.36, p<.05) of the mothers were significantly correlated with those of the daughters, after adjustment for mother's age, hight, weight, osteocalcin, Ca and energy intakes and daughter's weight, energy intake. In regression analyses, mother's BMD also were positively associated with daughter's BMD in lumbar spine, femoral neck, ward's triangle. Our findings support that mothers with low BMD tended to have daughters with low BMD. In the age groups studied, as well genetic factors as environmental factors may have an important role in determining BMD. This study suggests that women may successfully enhance their genetically determined BMD through adequate nutrient intakes and weight bearing exercise.

Forward head posture is one of the most recognized types of poor head and neck alignment. Poor head and neck alignment posture is a major contributor to compromised balance and neck pain, due to abnormal joint position sense and proprioception. Kinesio taping is an intervention method used clinically for the management of pain. Kinesio taping may produce its effects through pain reduction, stimulation of blood circulation, induction of muscle relaxation which provides correction of joint position, and providing stability to the muscles and joints without limiting the range of motion. Many studies have proved that kinesio taping has positive effects on the reduction of pain and improves alignment, on the other hand, some studies have not found. Kinesio taping may provide immediate pain relief and improved alignment following the application, but there is insufficient evidence to support sustained relief beyond that time and they recommended future studies to examine the benefits of kinesio taping as this would have a greater value in clinical practice. Therefore, this study is to investigate the effects of kinesio taping on the alignment of head posture and dynamic balance ability in people with forward head posture.

Air-containing fashion, which can offer diverse functions through the inflow and outflow of air, is highly relevant in today's mobile society, where people are experiencing a wider range of environments. This study attempts to suggest the possibility of air-containing multi-functional fashion that could continuously be utilized by developing a design for an air-containing jacket using modular systems. In this research, the modular systems in architecture and furniture design were referenced through a review of the literature for the purpose of establishing modular systems in fashion. Functions relevant to the mobility of today's society are derived from the results of advanced research and applied to the design of modules of the jacket. The modules are integrated through the modular systems. The folding and unfolding structure in architecture and furniture is applied as a folding system in fashion, the vertical accumulation structure as a layering system, and the horizontal integration structure as a combining system, and in addition, the containing system has emerged in fashion. Each module is designed to fulfill certain functions, such as cushioning, heat insulation, and portability. The folding system is utilized in designing the cushion module to support the neck and back of a wearer by making its hood and hem fold in the back. The application of a layering system was suggested by making the vest, combined with the neck cushion and back cushion via the combining system, layered with its insulation module. By applying the combining system, the hood that includes the neck cushion, the skirt that includes the back cushion, the body that includes the insulation module, and the sleeves can be connected and separated by a zipper. The applicability of this concept was proven by applying a developed design to an actual item.
