Background: The purpose of this study was to determine the effects of cervical extension-traction exercise on cervical alignment, pain, and neck disability in patients with mild turtle syndrome. Methods: Thirty two outpatients with mild turtle neck syndrome were recruited and randomly divided into two groups. Participants in the experimental group was applied cervical extension-traction exercise (CETE, n=16) and in the control group applied cervical stabilization exercise (CSE, n=16) for three times a week for 4 weeks. Results: Cobb angle and Jochumsen depth were CETE showed significant difference within the group post test (p<.05). And the CETE was significantly higher than the CSE. In the pressure pain threshold, both CETE and CSE showed significant differences within post test (p<.05). And the CETE was significantly higher than the CSE. Neck disability index were significant (p<.05) in the CETE post test. There was no significant difference between the two groups. Conclusion: Our results of this study showed that applying cervical extension-traction exercise to patients with mild turtle syndrome improved cervical alignment, pain and neck dysfunction.

The pipe with a long-neck flange is widely used in power plants, chemical plants, and shipbuilding companies. New the pipe with a long-neck flange is manufactured by welding a thick flange to a pipe. But this long-neck flange pipe has some deflects in the welding region such as unfitting and local thermal fatigue, which weaken the strength around the neck of the flange. Moreover, after welding the flange, the contacting surfaces of the flange have to be machined flat. So, that is uneconomical. Therefore, to solve the above problems of the long-neck flange pipe, a new process, which has no defects around the flange neck, is required. In this study, three forming processes are suggested to get an enhanced long-neck flange. First suggested process consists of conical terming and flange forming. Second and third suggested processes consist of the bulging of a long pipe locally heated by induction coils and the flange forming. The differences between second and third suggestions are the thickness and local heating area of the pipe. That is, the thickness of the initial pipe of third suggestion is larger than that of the final product, and the local heating area is smaller than that of second suggestion. These three suggestions fur forming a long-neck flange are simulated by FE analyses with a commercial cede DEFORM 2D. Especially, the theoretical result of FE analysis on the first suggestion fur forming a long-neck flange is verified by the experiment with aluminum 6063 pipes. From the theoretical and experimental results, it is concluded that three suggested processes are very useful in order to manufacture the pipe with a long-neck flange without any deflects.

This study classified the types of adult male shoulders through criteria which represent the characteristic of male shoulders important to jacket patterns. We selected 39 measurement items to provide information about Size Korea (2010) 3D bodice measurements. Collected data were processed with SPSS 20 for windows. Participants in the study were 1055 adult males, aged 20-60 divided into three age groups of 20-30, 40-50 and 60. Statistical tests (such as descriptive analysis and F-test) analyzed the data and ascertained the differences in ages. In a factor analysis and cluster analysis were conducted for the classification of shoulder type's adult males. The factor analysis indicates 6 factors with 82.4% of total variance. The shoulder types for adult male were divided into 3 groups, flat shoulder (14.1%), normal shoulder (72%), and slope shoulder (13.8%). A total of 19.9% of 20-30 was included in the slope shoulder type, 15.8% of 40-50 was included in the flat shoulder type and 16.1% of 60 was included in the flat shoulder type. This study classified the type of male shoulder through criteria that represent the characteristics of elderly male shoulder to neck base circumference, shoulder angle and shoulder type. The follow-up study will proceed with elderly male neck and various measurement items around the shoulder.

The purpose of this study was to compare torso pattern made by draping and flat pattern method in terms of the size of breast. The size of this study was classified as 75A and 75D according to the size of breast. Each torso pattern by the combination of the size and pattern method was compared and analyzed. In order to test the fit of the draping and flat pattern that was developed according to the size of breast, the outer appearance was evaluated. The results of the study were as follows: First, The most striking size difference was difference between the front and the back on bust line level, which decides on position of the side seam in comparison of size between draping and flat pattern of 75A and 75D. In the flat pattern, the difference between the front and the back in the size of breast was consistent regardless of a change in the size of breast. However, in the draping, the bigger breast led to the bigger difference between the front and the back on bustline level. Second, the flat pattern in 75D was evaluated to be the worst in 27 items among total 46 items for the evaluation of outer appearance in the draping and flat pattern of 75A and 75D. Third, regardless of size, the draping was evaluated to be more suitable in the areas related to neck, arm hole, and waist dart than the flat pattern. These results are suggesting that the draping is a method of reflecting characteristic of the body type more accurately than the flat pattern, and that the draping is a more suitable method than the flat pattern for the design of clothing pattern of the body type with big breast like 75D.

Injection laryngoplasty is simple and useful procedure in patient with vocal cord paralysis even under local anesthesia. For approaching vocal cord level, flexibility of neck mobility is required to operate injection laryngoplasty but it is relatively difficult to approach vocal cord in patient who has cervical fixations. Laryngeal mask airway (LMA) can be helpful:We use a LMA (I-gel$^{TM}$) during intubation without neck extension on flat supine position under general anesthesia and have a good operation filed. LMA with swivel connector give surgeons better surgical vision and make insertion of fibroscope easily during operation. Hyaluronic acid injection was done use needle (25 G, 5 cm) via percutaneous cricothyroid space : This procedure can be useful method for patients who suffer from not only weak voice but also dysphagia and aspiration high vagal palsy patient after spine surgery or uncooperative with awake injection laryngoplasty.

The purpose of this study was to provide basic data necessary for the development of clothing that can improve the satisfaction of body shape of elderly men by examining subjective characteristics and characteristics of perception type of older men's body shape. Using the Q methodology, I investigated and analyzed the process of formation and main characteristics of subjectivity of various types of recognition that elderly men express about their body shape. There were four types of perception of body shape in elderly men: flat hip and bird legs skinny body, back bent and abdominal obese body, thick neck and upper body development body, forward cervical neck and protruding abdomen obese body. The actual body shape of elderly men was classified according to the bust, waist circumference, hip circumference, and body part angle. But recognition body shape of elderly men was classified by visual factors like the abdomen, the angle of the neck, the inclination of the back, the slope of the waist, and the degree of obesity. It is necessary to consider the trend of silver fashion which is increasing in demand. In addition, it is necessary to develop clothing patterns of comfortable fit through ergonomic study on the physical characteristics of older men. Consideration should be given to the design and pattern that can reduce the difference between the ideal body shape and the body shape recognized by older men.

Background and Objectives: Hearing can be elicited in response to vibratory stimuli delivered to fluid in the external auditory meatus. To obtain a complete audiogram in subjects with normal hearing in response to pure tone vibratory stimuli delivered to fluid applied to the external meatus. Subjects and Methods: Pure tone vibratory stimuli in the audiometric range from 0.25 to 6.0 kHz were delivered to fluid applied to the external meatus of eight participants with normal hearing (15 dB or better) using a rod attached to a standard clinical bone vibrator. The fluid thresholds obtained were compared to the air conduction (AC), bone conduction (BC; mastoid), and soft tissue conduction (STC; neck) thresholds in the same subjects. Results: Fluid stimulation thresholds were obtained at every frequency in each subject. The fluid and STC (neck) audiograms sloped down at higher frequencies, while the AC and BC audiograms were flat. It is likely that the fluid stimulation audiograms did not involve AC mechanisms or even, possibly, osseous BC mechanisms. Conclusions: The thresholds elicited in response to the fluid in the meatus likely reflect a form of STC and may result from excitation of the inner ear by the vibrations induced in the fluid. The sloping fluid audiograms may reflect transmission pathways that are less effective at higher frequencies.
