The purpose of this study was to suggest menu pricing strategy based on understanding about customer perceived value of products and services. The technique known as PSM (Price Sensitivity Measurement) was used for analysis of price sensitivity for 3 menu items of a family restaurant in Seoul. A questionnaire was developed through literature review and modified after pilot test. Questionnaires for the main survey were distributed to 250 customers on their visit to the restaurant, and a total of 138 questionnaires were used for analysis (55.2%). The statistical analysis of price sensitivity was conducted using PSM, and descriptive analyses were conducted using SPSS Win (12.0). The main results of this study were as follows: the price sensitivity of beef tenderloin steak was higher than two other menus and the stress range of teriyaki chicken was almost 0, that is, the price sensitivity of teriyaki chicken was very low. Present menu prices of 3 menu items were within the range of acceptable prices, but had some distances from the optimal pricing point. From the result of this study, it was concluded that price adjustment or price promotion strategy would be effective for increase in sales of beef tenderloin steak, and marketing strategies to enhance consumers' perceptions of value should be conducted for all menu items by situations. Overall, PSM technique could be a helpful tool for researchers and managers of foodservice organizations to understand how consumers' perceptions of value are affected by the interaction of price and quality.

This statistical analysis of 4,709 legal autopsies performed in Korea in 2012 was conducted to obtain primary data about and related variables. The analysis revealed the following: 1. Of the total number of deaths, men accounted for and women, 26.8%. Evidently, the number of deaths among men was more than twice that among women. 2. With respect to mode of death, 54.8% were recorded as unnatural deaths, 39.2% were natural deaths, and 6.0% had unknown causes. Of the 2,581 unnatural deaths, 44.8% were accidental deaths; 27.2%, suicidal; 17.5%, homicidal; and 10.3%, undetermined. 3. Of the total number of unnatural deaths, 43.0% were trauma-related deaths, for which falling down was the leading cause, accounting for 33.5% cases. Asphyxiation was accounted for 17.2%, among which the predominant cause was hanging (55.3%). Moreover, 12.5% of deaths were due to drowning; 11.5%, poisoning; 11.2%, thermal injuries; 2.7%, complications in medical procedures; and 0.3%, electrocution, starvation, or neglect. 4. Among 1,847 natural deaths, heart diseases accounted for 50.2% and vascular diseases accounted for 16.7%. 5. There were 207 cases of deaths among children under the age of 10, of which 94 were unnatural and 49 were homicidal deaths. Of all cases, 9.2% had an unknown cause of death, and of these 67.6%, were putrefied or skeletonized bodies.

Primary pericardial mesothelioma is a rare tumor of mesodermal origin that is infrequently diagnosed antemortem and survival is short. A 60 year old male case of pericardial mesothelioma (epitheloid type) is reported. He was admitted to Yeungnam University Hospital because of chest pain, dyspnea, orthopnea and nonproductive cough. Chest x-ray suggested pericardial effusion. 2-D echocardiography showed echo free spaces of massive pericardial effusion and areas of thick hyperrefractile echoes arising from the pericardium. Pericardiocentesis was attempted and aspirated fluid was bloody exudates. Pericardial window operation with biopsy was done. Swan-Ganz catheterization showed equalization between right atrial pressure and pulmonary capillary wedge pressure. The pathologic diagnosis was established by histologic finding at pericardial biopsy.

The purpose of this study was to compare the clinical results of guided tissue regeneration(GTR) using a resorbable barrier manufactured from an copolymer of polylactic acid (PLA) and polylactic-glycolic acid(PLGA) with those of nonresorbable ePTFE bdmer. Thirty two patients(25 to 59 years old) with one radiographically evident intrabony lesion of probing depth > or =6mm participated in a Gmonth controlled clinical trial. The subjects were randomly divided into three independent groups. The fist group(n=8) received a ePTFE barrier. The second group (n=12) received a resorbable PLA/PLGA barrier. The third group (n=12) received a resorbable PLA/PLGA barrier combined with an alloplastic bone graft. Plaque index (PI), gingival index(GI), probing depth(PD) , gingival recession, clinical attachment level(CAL), and tooth mobility were recorded prior to surgery and at 3,6 months postsurgery. Statistical tests used to analyze these data included independent t-test, paired t-test, one-way ANOVA. The results were as follows : 1. Probing depth was significantly reduced in all groups at 3,6 months postsurgery and there were not significant differences between groups. 2. Clinical attachment level was significantly increased in all groups at 3, 6 months postsurgery and there were not significant differences between groups. 3. There were not signifiicant differences in probing depth, clinical attachment level, gingival recession, tooth mobility between second group (PLA/PLGA barrier) and third group (PLA/RLGA barrier combined with alloplastic bone graft) 4. Tooth mobility was not significantly increased in all groups at 3,6 months postsurgery and there were not significant differences between groups. In conclusion, PLA/PLGA resorbable barrier has similar clinical potential to ePTFE barrier in GTR procedure of intrabony pockets under the present protocol.

The statistical analysis of forensic autopsies provides basic data for the postmortem investigation system and is the foundation of the statistics used in the analysis of the causes of death. A statistical analysis was performed on national forensic autopsy data collected in the Republic of Korea during 2015 to overcome regional limitations and limitations from the number of unusual deaths in the current forensic autopsy research. A total of 6,610 cases were categorized based on the region, requested Police Agency or Coast Guard, gender, age, manner of death, and cause of death. Analysis of the manner of death revealed that 3,326 cases (50.3%) were unnatural death, 2,754 cases (41.7%) were natural death, and 530 cases (8.0%) were of unknown. Of the 3,326 cases of unnatural death, the majority (1,275 cases, 38.3%) were accidents, 1,040 cases (31.3%) were suicide, 481 cases (14.5%) were homicide, and 530 cases (15.9%) were undetermined death. Among the unnatural death, the majority (1,330 cases, 40.0%) were trauma, followed by 588 cases (17.7%) of asphyxia and 566 cases (17.0%) of poisoning. Fall down were the major cause of death by trauma (538 cases, 40.5%). On the basis of a previous study, there were 588 cases of asphyxia; strangulation was the major cause, with 472 cases (80.3%). Of the 2,754 cases of natural death, heart disease was the major cause (1,417 cases, 51.5%), followed by vascular disease (503 cases, 18.3%).

Reentrant tachycardias can often be terminated by discrete pacing stimuli that penetrate the reentrant circuit. Antitachycardia pacemaker PASAR 4172 (Programmable Automatic Scanning Arrhythmia Reversion, Model 4172, Telectronics) is designed to detect tachycardia automatically and subsequently to deliver programmed one or two extrastimuli to revert to sinus rhythm. We experienced two patients, one paroxysmal supraventricular tachycardia and one paroxysmal ventricular tachycardia, who had had frequent and often prolonged episodes of tachycardia that responded poorly to pharmacologic antiarrhythmic therapy. Each patient underwent a detailed preimplantation clinical electrophysiological study in order to determine the number of stimuli required for termination of tachycardia, the most satisfactory site for electrode placement, and the tachycardia termination zone. During the follow-up period of 7 to 11 months after implantation of PASAR 4172, no patient complained of an episode of sustained tachycardia although they experienced symptoms of an impending attack. We conclude that antitachycardia pacemaker PASAR 4172 is a safe, effective, and well tolerated method for the therapy of drug resistant paroxysmal supraventricular tachycardia and paroxysmal ventricular tachycardia.

Aortic dissection is clinically suspected from the typical symptoms and signs and may be confirmed by computed tomography or aortography. But atypical presentations can be seen in a minority of cases, such as SVC syndrome, right pulmonary artery stenosis etc. We present a case which was initially suspected to be a right atrial tumor because of a large filling defect in the right atrium on radionuclide angiocardiography but finally confirmed to be dissection of ascending aorta by computed tomography.

Ectopia cordis is defined as a congenital malposition of the heart partially or completely outside the thorax and often associated with sternal and congenital heart defects:surgical repair is generally unsuccessful because of the magnitude of the deformity and the associat-ed intracardiac anormalies. Four types of ectopia cordis are described : cervical, thoracic, abdominal and thoracoa- bdominal. Cervical and thoracic type are often fatal within days, because the heart is expo- sed and malformed. Abdominal type carries a better prognosis because cardiac abnormalities are less often found. The prognosis of thoraco-abdominal type mainly depends on the pre- sence of intracardiac abnormalities. We have experienced a case of thoracic ectopia cordis at 25 weeks' gestation by ultra- sonography, so present the case and the review with literature briefly.
