Lipoma is a circumscribed mesenchymal tumor originating from the adipose tissue. The lesion is usually small and asymptomatic. The most common location is in the neck region, however, lipoma can be found in the mediastinum in rare occasions. Although lipoma reach to the large proportions in the mediastinum, it rarely compresses the neurovascular structure. We present a case of a 58-year-old man, in which a hourglass-type cervicomediastinal lipoma produced Horner's syndrome with voice change. The man presented a swelling at the right side of his neck, ptosis and anhidrosis on the right side of his face, and right chest discomfort. After the removal of the mass, all the symptoms which had been provoked by compression, as well as Horner's syndrome and hoarseness, nearly disappeared.

Intracranial tuberculous subdural empyema (ITSE) is extremely rare. To our knowledge, only four cases of microbiologically confirmed ITSE have been reported in the English literature to date. Most cases have arisen in patients with pulmonary tuberculosis regardless of trauma. A 46-year-old man presented to the emergency department after a fall. On arrival, he complained of pain in his head, face, chest and left arm. He was alert and oriented. An initial neurological examination was normal. Radiologic evaluation revealed multiple fractures of his skull, ribs, left scapula and radius. Though he had suffered extensive skull fractures of his cranium, maxilla, zygoma and orbital wall, the sustained cerebral contusion and hemorrhage were mild. Eighteen days later, he suddenly experienced a general tonic-clonic seizure. Radiologic evaluation revealed a subdural empyema in the left occipital area that was not present on admission. We performed a craniotomy, and the empyema was completely removed. Microbiological examination identified Mycobacterium tuberculosis (M.tuberculosis). After eighteen months of anti-tuberculous treatment, the empyema disappeared completely. This case demonstrates that tuberculosis can induce empyema in patients with skull fractures. Thus, we recommend that M. tuberculosis should be considered as the probable pathogen in cases with posttraumatic empyema.

A split-die design for the cold forging of symmetric parts such as those having a hexagonal cross-section is presented in this paper. Parts with a hexagonal cross-section, such as bolt heads and nuts, should be forged with a die that has a hexagonal-shaped hole. A split type die is required to mitigate the buildup of stress concentrations located at the corners of the hexagonal hole. Generally, the insert of a hexagonal die is made by cutting each corner of a cylinder using a hexagonal hole and then combined with the die and shrink-fitted. However, split dies face problems when extruding material at the corners of the hexagonal split die. To address this problem, two types of split dies were evaluated: rounded hexagonal dies and angular hexagonal dies. The effects of the pre-stress ring on the dies were compared and analyzed and results show that using the angular split hexagonal die can extend the lifetime of forging dies.

The source of a business competition is man and the core of a business success depends on people's ability, efforts and cooperation. Therefore, modern managers are making varied efforts to perform the ethical management for the organization immersion and job satisfaction of the employees. The managers of the financial agencies including the enterprises competing in the global market, face numerous ethical issues and problems. Considering the reality that financial institutions are actively asked to perform the responsibility and duties sincerely, the tasks how the head of financial agency will accept the social study of the level of ethics and change the level of recognition, and how he will settle it as the natural feature in the institution, become an important management target. In addition, it is necessary to figure out how the ethical management of the head of the financial agency will affect the organizational immersion of the employees. Based on the objective of this study, we attempted to confirm how the ethical management will of the head of the financial institution would affect the organizational immersion, the employees' mental result variables. Through this study, it became necessary for the directors of the financial institutions to search for the methods to improve the system of management and enhance the observance will of the business ethics so that they may not cause the disposition of the violation of the business ethics owing to the enforcement to achieve the target of the results of the business or the error recognition of the norm. Further, the heads of banks will have to set a management policy focused on the democratic management and the ethical justice based on the participating methods to induce the cooperative commitment of the stock company employees not to be shifted from the globalization and the competitive society.

This study was examined the effective nonverbal behavior cues of detecting suspects' lies in the investigation scene. In order to search the suspects who drank the alcohol liquor without a permission, 18 soldiers were interviewed. 8 solders had drunken alcohol and had lied when was asked(lie group). The other 10 soldiers hadn't drunken alcohol and had told the truth(truth group). The mean frequencies of nonverbal behaviors were compared lie group with truth group. The following behaviors were measured by frequency: vocal characteristics (high pitch of voice, speech hesitations, speech error, frequency of pauses, period of pauses, latency period), facial characteristics (gaze, smile, touching face, blinking, facial micro-expression), body movement (illustrators, hand and finger movement, leg and foot movement, head movement, trunk movement, shifting position). As results, this study found that deception cues were periods and frequencies of pause, micro-expression, head movements. The lie group had less periods and frequencies of pause, and more micro-expression, head movements than truth group. But, this study didn't found Othello's error cues.

Achondroplasia and hypochondroplasia are the two most common forms of short-limb dwarfism. They are autosomal dominant diseases that are characterized by a rhizomelic shortening of the limbs, large head with frontal bossing, hypoplasia of the mid-face, genu varum and trident hands. Mutations in the fibroblast growth factor receptor-3 (FGFR3) gene, which is located on chromosome 4p16.3, have been reported to cause achondroplasia and hypochondroplasia. More than 98% of achondroplasia cases are caused by the G380R mutation (c.1138G>A or c.1138G>C). In contrast, the N540K mutation (c.1620C>A) is detected in 60-65% of hypochondroplasia cases. Tests for common mutations are often unable to detect the mutation in patients with a clinical diagnosis of hypochondroplasia. In this study, we presented a case of familial hypochondroplasia with a rare mutation in FGFR3 identified by next generation sequencing.

TBM (Tunnel Boring Machine) tunnel should be carry out with the adopted machine until the end of excavation because of impossibility of replacement or modification of machine. Observation of the face of the tunnel is difficult, especially in EPB(Earth Pressure Balance) shield TBM, predict changes in the ground condition with analyzing data, collected during the excavation, and it should be reflected in construction. Until recently, subjects of studies on TBM are mainly the determination of machine and the development of advance rate prediction model, according to the characteristics of ground which is the target of excavation. However, study focused on the estimation of ground conditions and the improvement in operational methods using excavation data of TBM equipment, the principal of the excavation, has been done not so much. This study examine the variances in advance rate depending on changes in operating conditions and evaluate the optimal operating conditions of adopt machine, using working data obtained from EPB shield TBM project. The result of this study is suggested as follows. First, cutter head RPM and total thrust force are biggest influences on advance rate, Second, it is recommended for proper advance rate that total thrust force is controlled while optimum cutter head RPM is kept, Third, according to the increasing trend of total thrust force, the changes in ground conditions can be predicted, the appropriate operating conditions can be determined.

Clear cell hidradenoma (CCH) is a rare tumor of the sweat glands of eccrine or apocrine differentiation. It can occur anywhere in the body, but common sites of involvement are the head, face, trunk, and extremities. Although several reports have described sonographic findings of CCH, only one study on the axilla mentioned its strain elastographic findings. Here, we present a case of CCH in the right calf with its sonographic and strain elastographic findings in a tumor that looked like an epidermoid tumor.

The purpose of this study was to investigate the putter head movement during the putting strokes. Highly skilled 5 golfers(less than 3 handicaps) and 5 novice golfers(having no golf experience) participated in this study. A target distance was 3 m. Movements of the putter head were recorded at 60 Hz with two video cameras. The results showed that the novice golfers moved the club significantly longer than the expert golfers(p<.0001). Accoring to a movement time, novice golfers moved their club significantly faster than the expert golfers(p<0.001). Novice golfers could not control the club head effectively, and could not hit the ball correctly. Based on the impact zone movement, sweet spot of novice golfers moved faster(along the line of putt), higher(along the vertical line), and wider(along the side to side line) than that of expert golfers.
