Background: Individuals with forward head posture (FHP) have neck pain. To correct the FHP, a posture correction band is commonly used. However, we do not know the posture correction band influenced the pulmonary function in individuals with FHP. Objects: This study aimed to elucidate the effects of the posture correction band on the pulmonary function in young adults with neck pain and FHP and to monitor how the pulmonary function changed over time. Methods: Twenty subjects with chronic neck pain and forward head posture were recruited. Subjects performed pulmonary function test four times: before, immediately, and 2 hours after wearing the postural band, and immediately after undressing the postural band. Vital capacity (VC), forced vital capacity (FVC), peak expiratory flow (PEF), and forced expiratory volume at one second (FEV1) were measured. The modified Borg dyspnea scale was used to measure each subject's responses to the posture correction band. The mixed-effect linear regression was used to the effect of the posture correction band over time. Results: There were no significant differences in VC, FVC, PEF, FEV1 values over time (p > 0.05), although all values slightly decreased after applying posture correction band. However, the score of the modified Borg scale significantly changed after wearing the postural bands (p < 0.05), indicating the subject felt discomfort with posture correction band during breathing. Conclusion: Because the posture correction band did not change the pulmonary function over time, but it induces psychological discomforts during breathing in people with FHP. Therefore, this posture correction band can be used for FHP realignment after discussion with the subjects.

With the outbreak of COVID-19 a few years ago, video conferencing and electronic document work have increased, and for this reason, the proportion of computer work among modern people's daily routines is increasing. However, as more and more people work on computers in the wrong posture for a long time, the number of patients with poor eyesight and text neck is increasing. Until recently, many studies have been published to correct posture, but most of them have limitations that users may experience discomfort because they have to correct posture by wearing equipment. A posture correction sensor algorithm is proposed to prevent access to the minimum distance between a computer monitor and a person using an ultrasonic sensor device. At this time, an algorithm for minimizing false alarms among warning alarms that sound at the minimum distance is also proposed. Because the ultrasonic sensor device is used, posture correction can be performed without attaching a device to the body, and the user can relieve discomfort. In addition, experimental results showed that accuracy can be improved by reducing false alarms by removing more than half of the noise generated during distance measurement.

Introduction: Endoscope-assisted open reduction and internal fixation (EAORIF) reduces the amount of facial scaring, but limitations, such as the possibility to convert to the open technique and the large learning curve, remain. Materials and Methods: The medical records of 19 patients diagnosed as lateral overridden subcondyle fractures and treated with endoscope-assisted open reduction and internal fixation at Yonsei University Health System from December 2006 to August 2010 were reviewed. Results: 11 patients underwent temporary discomfort or pain such as limitation of mouth opening, temporomandibular joint discomfort, lip paresthesia or facial weakness, but the symptoms disappeared within 3 months. There was no severe long-term complication except 2 patients with re-fractures of operated subcondyles. Conclusion: Subcondyle fracture with lateral overridden proximal segment is a better indication of endoscope-assisted open reduction and internal fixation than a condylar head/neck fracture, or medial overridden subcondyle fracture: allowing an anatomic reduction.

This study was performed to measure the posture correction effect of wearing ergonomic experimental clothing. Two types of experimental clothing (A, B) were developed. Both of them reinforced the muscles surrounding the spine. Experimental clothing A was developed by reflecting the shape and position of the pectoralis major muscle, abdominal muscle, and latissimus dorsi muscle. Experiment clothing B was developed by reflecting the integrated form of those muscles. Subjects were males in their 20s~30s (n=32). They were divided into two groups based on their acromion distance (AD): the turtle neck syndrome group (n=16, AD=3.81cm) and the normal group (n=16, AD=1.27cm). The correction of body posture was detected by three index values: change of the cervical curvature angle, horizontal distance between the seventh cervical vertebra and tragion, and AD. The comfort and tightness of the clothing were also measured. The results showed that both types of experimental clothing corrected body posture and that turtle neck syndrome can be prevented by wearing these types of posture correcting clothing. Two index values were decreased: cervical curvature angle ($0.31{\sim}1.32^{\circ}$) and horizontal distance between seventh cervical vertebra and tragion (0.22~0.31cm). The chest was also stretched. The comfort was rated as good for both types of experimental clothing. These results indicate that the experimental clothing had a posture correction effect without any discomfort for daily living.

Background and Objectives : Sulcus vocalis could be classified into type I, type IIa, and type IIb. There have been a little reports about voice quality and treatment results related with types of sulcus vocalis. The authors conducted an analysis of voice and treatment according to different types of sulcus vocalis. Materials and Methods : This study was based on a retrospective chart review. The sulcus types were classified into type I and type II. Objective and subjective voice assessments were analyzed. Patients were treated individually with voice therapy, percutaneous steroid injection, and injection laryngoplasty. Comparison was performed on the voice difference between type I group and type II group, and between pre-treatment and post-treatment of each types. Results : One hundred and one patients were enrolled into this study, and 49 patients were type I and 52 patients were type II. Type I group showed longer mean maximal phonation time (MPT) than type II group, although other voice parameters didn't show any difference between two groups. Even after the management, almost all of the voice parameters didn't show improvement except MPT of type II group. Conclusion：Although the type I sulcus has been known as a non-pathologic lesion, it can result in some degree of voice change and discomfort, and thus need an active management. In this study, voice therapy, percutaneous steroid injection, and injection laryngoplasty showed limited effect to the both types of sulcus vocalis. Further studies for management of sulcus vocalis were needed.

Objectives and Backgrounds : After parotidectomy, some of patients complain gustatory sweating, facial flushing and discomfort in the same area. A series of these symptoms are supposed to be caused by the aberrant regeneration of the secretory parasympathetic fibers to sweat glands and blood vessels of the skin following parotidectomy. In this study, we want to compare the efficacy of thermography to the Minor's starch-iodine test for determining the presence of Frey's syndrome. Materials and Methods : 48 patients who underwent total or superficial parotidectomy from March 2002 to December 2004 were selected for this study. A subjective clinical questionnaire and the objective Minor's starchiodine test were performed to evaluate the incidence of this syndrome. Total 21 patients were confirmed as positive Frey's syndrome and infrared thermography was performed for them. Result : Frey's syndrome occurred in 21 patients(43.8%). The average temperature of parotidectomy site and normal opposite area were $27.65^{\circ}C\;and\;26.41^{\circ}C$ respectively. Thermography showed temperature difference in 20 patient(95.2%) and the difference of temperature was statistically significant above $1.0^{\circ}C$(p<0.001). The severity of symptoms were related with the difference of temperature(p<0.05). Conclusion : Thermography is useful, non-invasive, simple and quantifying method to diagnose Frey's syndrome. Additionally, this geographic diagnosis is available to show the accurate area for botulinum toxin injection.

Background: Smartphone addiction has emerged as a significant social problem. Numerous studies have indicated the association between smartphone use and discomfort in the musculoskeletal system of the upper extremities. Objects: This cross-sectional survey aimed to compare the characteristics of musculoskeletal pain in the neck, trunk, and upper limbs between individuals with smartphone addiction and those without addiction. Methods: We collected a total of 326 healthy individuals' data from China and Korea who had owned and used smartphones for more than 5 years between 20-50s through an online questionnaire consisting of 84 questions in four major sections. The first part contained basic information on the participant's personal characteristics and smartphones. The second part contained questions about smartphone use and posture. The third part was the smartphone addiction. The fourth part was to investigate musculoskeletal pain in various upper body parts. Results: Smartphone addiction has a weak negative correlation with age (r = -0.20, p < 0.01) and a weak positive correlation with the hours of smartphone use (r = 0.376, p < 0.01). Frequent musculoskeletal pain symptoms related to smartphone use were observed in the neck, shoulder, lower back, and wrists. The hours of smartphone use was slightly positively associated with the prevalence of musculoskeletal pain in the shoulder (r = 0.162, p < 0.05) and lower back (r = 0.125, p < 0.05). The prevalence of musculoskeletal pain in the neck (χ² = 3.993, p < 0.05), shoulder (χ² = 6.465, p < 0.05), and wrist (χ² = 4.645, p < 0.05) was significantly higher among females than males. Conclusion: The results suggest that smartphone addiction should be recognized as a dual concern encompassing both physical health and psychosocial aspects. Furthermore, healthcare professionals, including physicians and physical therapists, should consider clients' smartphone usage patterns when assessing and treating with musculoskeletal pain.

Many patients of acute myocardial infarction showed delay time before seeking treatment although they needed immediate thrombolytic therapy once they perceived their symptoms. The objectives of this study were to identify the relationship between clinical symptoms and the delay, and to find the time spent before seeking the treatment. This study was a retrospective research. The delay time for the treatment consisted of the length of delay from symptom onset to patients' decision (T1), from patients' decision making to finding transportation (T2), and from taking transportation to the first hospital arrival(T3). The subjects were 89 patients who were admitted in the ICU and Cardiac Ward at Chonnam University Hospital with the first attack of acute myocardial infarction. Center, USA The data was collected for three months from March 1st to May 31st of 1998 through questionnaires and reviewing patients' charts: The chart information was suppled by two nurses working at the ICU and Cardiac Ward. The data was analyzed by using frequency, mean and ANOVA through the SAS program. The results of study summarized as follows: 1. Sixty two patients (69.7%) were male and twenty seven patients (30.3%) were female, the ratio of male to female was 2.3 : 1. 2. In daily life, the 70.8% of the patients felt chest pain and discomfort fatigue in 67.4%, dyspnea in 57.3%, and pain in arm, neck, and jaw in 52.8%. During the attack, 97.8% of the patients felt chest pain and discomfort dyspnea in 82.1%, pain in arm, neck, jaw in 67.4% and perspiration in 51.7%. 3. The length of time a patient spent seeking time for treatment (T1+T2+T3) was 94.6 minutes, in which the time for patients' decision making for treatment (T1) was 70.3 minutes, time for finding transportation (T2) was 8.2 minutes, and time for the transportation of the patient to the first hospital (T3) was 16.1 minutes. Time for patients' decision making to go to a hospital(T1) was 74.2% of the total time sought for treatment. 4. The differences of time sought for treatment between perceptions about the seriousness of the symptoms were significant (F= 6.5, p< .01). The more serious the heart symptoms they felt, the shorter the seeking time for treatment. 5. The differences of the time delay before treatment between the degree of the symptoms were significant (F= 2.9, p< .05). The patients with the typical chest pain and discomfort spent shorter the seeking time for treatment than those with the atypical symptoms of acute myocardial infarction. 6. The differences of transportation time to the first hospital between the types of cars that the patients used, were significant (F= 4.3, p< .01). When the patients used 119 or 129 they spent the least time (5.3 minutes) for transportation, and followed by way of an ambulance (15.6 minutes), private car (20.6 minutes), and taxi (24.8 minutes).

Recently, young men have become more muscular as they become more interested in physical figure. However, most of these muscular men have fit problems regarding ready-made clothes. In view of this, this study aimed to develop a prototype jacket pattern for muscular men. For this study, five muscular men were selected to put on existing jacket pattern for wearing tests. The regression formula, in which muscular men body measures were adopted, was applied to unsuitable parts, especially the areas determined not to be appropriate in the evaluation of existing jacket pattern wearing tests. After the first and the second jacket pattern wearing tests, the final jacket pattern suitable for muscular men was developed. The results of the study were as follows: In order to make up for the problem of the loosening of the lapel area, due to the development of the chest muscle, the chest circumference line on the chest area of the pattern was cut to be 1.0cm wide; thus, the front length was modified with an increase. The wearing tests found that a wearers felt discomfort from the tight armhole area, so the armhole depth was set to be a little lower than that of ready-made clothes. A muscular men needs much more extra quantity in this area because the upper part of the back side is projected due to the greater development of the trapezius muscle and the deltoid than in average men. Hence, concerning the standard line for the length of the back interscye, ease of 1.0cm was added to the regression equation formula {(0.371${\times}$chest circumference+3.145)/2} in order to resolve the discomfort with the back area. Also, for the biacromion length, the upper arm protruded more than the shoulder point of the jacket because of the development of the deltoid and the upper arm muscle, and it was set to be wider than the actual shoulder. In order to solve the problem of discomfort from the narrow neck area during the wearing of a jacket owing to the development of the trapezius muscle, extra ease of 0.5cm was added to chest circumference/12-0.5cm in the existing jacket prototype to the width of back of the neck, and it was corrected to be chest circumference/12.

Objectives : Vertigo is a sensation of spinning while stationary. It is commonly associated with nausea or vomiting, unsteadiness (postural instability), falls. It can affect a person's thoughts and life style. Recurrent episodes in those with vertigo are common and frequently impair the quality of life. The purpose of this study was to report the clinical effects of herbal medicine on vertigo.Methods : We employed oriental medical treatments; herbal-medication (Banhabaekchulcheonma-tang gamibang), acupuncture and moxibustion. At the same time, the blood cupping therapy in the neck area was applied. We treated the patients two or three times a week with oriental therapy methods. They took medicine three times a day after a meal. During taking medicine, we let the patients avoid fatty food, flour based food, and alcohol. We determined the course of treatment with visual analogue scale (VAS). We let them respond to a VAS item between 0 and 10 point continuously. The symptoms that we evaluated were vertigo, headache, chest discomfort, nausea and vomiting.Results : After taking treatment - acupuncture and moxibustion during some period and taking herbal-medicine, the VAS scale was gradually getting decreased. Generally the symptom of vomitting and nausea was eased at first, and then the symptom of chest discomfort, headache, vertigo was relieved.Conclusions : Banhabaekchulcheonma-tang gamibang was effective in the treatment of vertigo and its related symptoms, headache, chest discomfort, nausea and vomiting.
