A 70-year-old male visited urgent care due to coughing for 1 month and left chest pain. He had no history of trauma. The initial chest computed tomography (CT) showed the 7th left intercostal lung herniation. A follow-up CT showed an intercostal lung herniation combined with a bowl herniation, which had developed due to a Morgagni's hernia. An emergency operation was performed due to the incarceration of the bowl and lung. The primary repair of the diaphragm was performed and the direct approximation of the 7th intercostal space was determined. We concluded that the defect of the diaphragm and the intercostal muscle was a congenital lesion, and the recurrent coughing was the aggravating factor of herniation.

Many teeth have been mistakenly extracted or endodontically treated because of an incorrect diagnosis of orofacial pain including toothache, A case report of persistent toothache originating from a malignant lymphoma of left maxilary sinus is presented. Root canal therapy and extraction of left upper quadrant teeth from canine to second molar did not resolve the chief complaint. The patient was referred to a neurologist and was diagnosed with a malignant lymphoma, a rare lesion of the maxillary sinus. The case stresses the importance of malignant neoplasms of maxillary sinus as a potential etiologic factor in the differential diagnosis of orofacial pain.

This paper presents a three-dimensional finite element method analysis of repairing plate with bonded composite patch subjected to tensile load. The effect of the corrosion on the damage of the adhesive (FM73) in the length of two horizontal cracks on the both sides is presented. The obtained results show that the crack on the left side creates a very extensive area of the damaged zone and gives values of the stress intensity factor (SIF) higher than that on the right side. We can conclude that the left crack is more harmful (dangerous) than that on the right side.

Objectives : The purpose of this study is to develop the method of selecting representative pulse wave. Methods : The pulse waves were acquired at the right and the left Guan point(關部) with 1420 people who were apparently healthy. The shape agreement of right and left pulse wave and the floating-sinking ratio were compared with three cases, which were the pulse height based method, the pulse area based method, and the pulse time based method. Results : In the point of the shape accordance, the pulse time based method was the best, and the pulse area based method was the worst. In the point of the floating-sinking ratio, the pulse height based method was the worst, and the pulse time based method was the best. Conclusions : So, the pulse time based method was recommended for selecting the representative pulse wave. This study compared the selection methods of representative pulse using the physiological characteristics of pulse wave. Further studies are required, because the representative pulse wave is the main factor of determining the shape and the floating-sinking characteristic of the pulse wave.

Low back pain has been known as the most frequent musuculoskeletal disorders in modern industrial society and cost by low back pain is increasing mon and more. The asymmetric lifting has been identified as a major risk factor of low back pain. In this study, the muscle activity and muscle exertion level during asymmetric load handling (without trunk flexion) was estimated. The results of normalized MVC measurement were decreased about 16％, 24％, 34％ respectively as the asymmetric angle was $30^{\circ}$, $60^{\circ}$, $90^{\circ}$. From the results of EMG measurement contralateral muscles were more active than ipsilateral muscles. RMSEMG values of right erector spinae muscles were decreased as the work posture went to 90$^{\circ}$ and those of left erector spinae muscles were increased until the asymmetric angle was 40$^{\circ}$ but decreased continually over 40$^{\circ}$. And for seven of subjects, activities of left and right latissimus dorsi muscles were maintained constantly, while for remainer, those were irregular.

A great variety of penetrating injuries is happening due to the increasing population and violence today. An optimal surgical approach is the key factor for successful repair of a complicated penetrating injury. A 23-year-old woman fell down the stairs from the second floor and received cervico-thoracic penetration injury due to a metalic bar. The metalic bar ruptured the right jugular vein and penetrated the left upper and lower lung. Under cervico-median sternotomy, neck vessels were repaired and the left thorax was successfully entered to repair the damaged lung through the mediastinal pleura. With this approach, the patient's position did not need to be changed during operation, while reduced the operation time compared to the conventional approach (cervical incision and standard thoracotomy).

We study optical quantum transition line widths in relation to magnetic field dependence properties of the electrons confined in an infinite square well potential system between z = 0 and z = L_z in the z - direction. We consider two systems-one is subject to right circularly oscillating external fields and the other is subject to left circularly oscillatory external fields. Our results indicate that the line widths of right circularly oscillating external fields is larger than the line widths of left, while the opposite result is obtained for the line widths.

This study aims to find satisfactory or unsatisfactory factors that startups either currently being occupied in or already left the business incubator made in a survey with a total of the sixteen firms responded. Among the sixteen, ten were the firms that have occupied in the business incubator and the six firms left the incubator. Mostly, the firms were satisfied with the incubator's roles with showing 4.4 satisfaction. The support for business facilities were the number one factor for the incubator has to do with the firms had positive answers from the firms. However, support for the production or sales showed less satisfaction compared to business facilities, a need that the incubator should improve the roles for the future. The results of this study can contribute to the development of medium and long-term plans for the business incubator.

Purpose: The purpose of this study is to investigate the therapeutic use of Hepatocyte growth factor(Adv.CMV.HGF) in temporomandibular joint disc defect. Materials and methods: Twelve New Zealand white rabbits, weighing 2.5 - 3.0 kg, were used in this experiment. Defects(2 mm in diameter) were created in their TMJ discs. Recombinant Adv.CMV.HGF with gelatin sponge($Gelfoam^{(R)}$) as carrier was implanted in the defects. We divided the rabbits into four batches according to the duration of the implantation - of 1, 4, 8, 12 weeks - and both left and right TMJ of each rabbit in all groups were used in the research : left joints were used as experiment group and right were control group. Each batch of rabbits was killed one, four, eight and twelve weeks after the experimentation respectively, and called Group A, B, C, and D. (Group A = 1 wk, B = 4 wks, C = 8 wks, and D = 12 wks) Results: The experimental group showed a significant increase in the number of chondroblasts and active cell differentiation at the margin of the defects. Compared to the control group, in the experiment group chondroblasts increased and chondrocytes showed a columnar arrangement, which is witnessed at the time of cell differentiation. Conclusion: This study supports the case that Avd.CMV.HGF may be useful in the repair of articular disc of the rabbit TMJ.

This paper presents a factor-analysis based questionnaire categorization method to improve the reliability of the evaluation of working conditions without influencing the completeness of the questionnaire both in Taiwanese and Chinese construction enterprises for structural engineering applications. The proposed approach springs from the AI application and expert systems in structural engineering. Questions with a similar response pattern are grouped into or categorized as one factor. Questions that form a single factor usually have higher reliability than the entire questionnaire, especially in the case when the questionnaire is complex and inconsistent. By classifying questions based on the meanings of the words used in them and the responded scores, reliability could be increased. The principle for classification was that 90% of the questions in the same classified group must satisfy the proposed classification rule and consequently the lowest one was 92%. The results show that the question classification method could improve the reliability of the questionnaires for at least 0.7. Compared to the question deletion method using SPSS, 75% of the questions left were verified the same as the results obtained by applying the classification method.
