The purpose of this study is to present the reference values for cardiac size and cardiothoracic ratio change, normal range and diagnosis of cardiovascular disease in pregnancy and non pregnancy of normal Korean women using chest X-ray. The subjects of this study were 58 women, who were read as normal by chest radiologist, had chest radiography taken on both last month of pregnancy, pre-pregnancy and within 2 years following delivery. In this study, we defined the last month of pregnancy as pregnancy and before or post pregnancy as non-pregnancy. CS and CTR were measured by two radiological technologist who had clinical experience more ten years with Danzer's method. Statistical methods were paired t-test and one-way ANOVA. Significance level ${\alpha}$ was 0.05 and p-value 0.05 or less was statistically significant. For pregnancy, the mean of left and right cardiac size was $40.11{\pm}8.73mm$ and $89.51{\pm}11.9mm$, CS was $128.60{\pm}13.15mm$, CTR was $44.51{\pm}4.21%$. In non pregnancy, $36.50{\pm}8.18mm$ and $77.68{\pm}13.1mm$. CS and CTR were $114.18{\pm}14.28mm$ and $42.03{\pm}4.04%$. Both pregnancy and non pregnancy, the difference of the mean value in left and right cardiac size, CS and CTR were statistically significant (p<0.01). but comparing mean on age, height and weight, the difference of the mean value between groups was not (p>0.05). In the result of this study, the mean size of CS increased by 12.6% in pregnancy($128.60{\pm}13.15mm$) compared to the non pregnancy($114.18{\pm}14.28mm$), and increased by 9.8% in the right side of the heart and 15.2% in the left side. The mean size of CTR increased about 5.9% in pregnancy ($44.5{\pm}4.21%$) compared to non pregnancy($42.03{\pm}4.04%$).

Objectives: Chronic insomnia disorder is a common and one of the most distressing sleep disorders. This pilot study was conducted to compare the spatial function between insomnia disorder patients and good sleeping control. Methods: We enrolled the 22 patients with chronic insomnia during over one year who met the DSM-5 diagnostic criteria of insomnia disorder and 27 normal sleeping controls. The Cambridge Neuropsychological Test Automated Battery (CANTAB) has been performed to compare the spatial cognitive function between insomnia disorder patients and good sleeping controls. Results: The CANTAB results showed significant differences in the problems solved in minimum moves of Stockings of Cambridge test (t = -2.499, p = 0.017). The significant difference between two groups remained after controlling age, sex, and Beck Depression Index non-sleep scores (F = 5.631, p = 0.022). Conclusion: This study suggests that the patients with insomnia disorder have poor spatial planning function.

The purpose of this study was to examine the correlation between Juvenile alcohol use and their criminal patterns. The data were collected through questionnaire surveys. Subjects serving for this study were 971 delinquent adolescents in Korea, sampled from 6 juvenile corrective institutions and 2 classification judging institutions, using a census method. Their age range was between 12 and 21. Data were analysed by IBM PC using SAS program. Statistical methods employed were Chi-square and frequency analysis. 1. Of 877 respondents, the number of adolescents committed criminal behaviors while the intoxicated were 230(26.2%), and 647(73.8%) were in a non-intoxicated state. 2. Adolescent under intoxication showed a higher rate of aggressive crimes and assault crimes, whereas adolescents under the non-influence of liquor tended to commit property climes and violations of criminal special law Drunken state adolescents during committing criminal behaviors used knifes, stones or fist-kicking as criminal tools, whereas drug use or without weapons in non drunken state. Most crimes have happened without any tools in both group. 3. In comparison of the alcohol user and the non-user, most alcohol-related crimes among adolescents were committed at AM 0:00 to AM 4:00 during the weekend in the dark, cloudy, and stormy-rainy day, while non-alcohol related crimes were at afternoon of weekday in the clear day. The places that the criminal activities occurred were streets, amusement places such as disco-theque, fields and their own house among alcohol users, whereas victim's house, another person's house and restaurant were chosen among non-alcohol users. 4. The victims assaulted by Juvenile offenders in both drunken and non-drunken state were mostly passer-by(65.4%), followed by their friends(25.1%). And the conditions of victims showed a significant differences between the drunken adolescents and the non-drunken adolescents. The victim's conditions assaulted by intoxicated delinquent adolescents were in quarreling or drunken state, whereas non-alcohol related crimes were directed against victims in a sleeping or irresistible state. 5. Almost over the half of delinquent adolescents perceived their delinquency as wrong behaviors. and alcohol non-user tended to more significantly perceive their criminal acts as wrong conducts. About the half of respondents answered that they committed their criminal acts in spite of having a very good Judgement while doing crimes, the author did not found a significant difference between the two groups. The reasons given for crimes were manifested as follows: it can be seen that ‘to get money for amusements’(30.4 % of all motives) were most common, followed by ‘to commit accidentally the offences’(23.8%), ‘curiosity or heroism’(18.9%). alcohol related crimes tended to be accidental and impulsively without any clear planning, while non-alcohol related crimes tended to be purposeful, directed to make money motivated by curiosity or a desire to live heroically. In Conclusions. the correlation between alcohol use and Juvenile criminal behaviors has been examined in this study. Generally, alcohol use had been found to be highly correlated with aggressive assault crimes including robbery, burglary and rape etc.

The purpose of this study is to compare voice characteristics and voice-related quality of life (K-VRQOL) of the elderly female choir members using perceptual-auditory voice quality evaluation (GRBAS) and K-VRQOL scales. The participants were 77 women over 60 years old who were actively engaged in the choir in either Seoul or Busan. There are two kinds of choirs that indicate different engagement levels: regular choir and church choir. The perceptual-auditory vocal quality evaluation was listened to by / a / vowels and were graded by experts using the GRBAS scale. As a result, when comparing the differences between groups, the elderly female participants of the regular choir showed higher satisfaction in speech using the subjective speech recognition level than the elderly female members who performed in the church choir. In addition, the analysis showed that the satisfaction level was high in the physical function area of the K-VRQOL scale. This study confirmed that choral activities could yield positive results not only in terms of improving voice function in old age, but also to improve the subjective perception level of voice use, thus suggesting the necessity of systematic music programs to improve voices that are aging.

Purpose: Ultrasound-guided epidural caudal block for low back pain and radiating pain is often performed in the treatment of outpatients. However, this procedure has a failure rate of up to 25% even when it performed by an experienced physician. The authors investigate the effectiveness of Ultrasound-guided epidural caudal block in patients related to disc herniation or spinal stenosis. Materials and Methods: Ultrasound-guided caudal epidural block was performed in 55 outpatients with LBP and radiating pain. Patient was placed in the prone position and sonographic image of sacral hiatus was obtained using linear probe. A 22-gauge needle was advanced into the sacrococcygeal membrane under ultrasound guidance and then medication was injected into the caudal epidural space. There were 31 cases of disc herniation, and 24 cases of spinal stenosis. Patients were evaluated by Visual Analog Scale (VAS) pain score at pre-treatment, post-treatment, 2 weeks and 4 weeks by telephone interviews. Results: 53 of the 55 cases (96.4%) of needle insertion into the sacral canal under ultrasound guidance were successful. Gender was not significantly different between disc herniation group and spinal stenosis group. But there was a significant age difference between disc herniation group ($42.3{\pm}10.8$), and spinal stenosis group ($62.8{\pm}15.1$) [p<0.001]. The VAS score at pre-treatment, post-treatment, 2 weeks, 4 weeks in disc group were 6.84, 3.1, 1.8 & 1.77. The VAS score at pre-treatment, post-treatment, 2 weeks, 4 weeks in spinal stenosis group were 6.88, 3.58, 4.33 & 4.88. The VAS score in both groups was significantly improved after the procedure (p<0.001). Over time, the two groups were statistically significant differences in VAS score after adjusting for age (p<0.001). Conclusion: Ultrasound-guided caudal epidural block seems to provide a high success rate and a significantly better response in disc group than spinal stenosis group.

Purpose: We wanted to compare the results between cadaveric and radiological measurements of calcaneus. Materials and Methods: Sixty three calcaneus of 33 cadavers donated between December 2012 and December 2014 were actually measured. Computed tomography (CT) images of 244 calcaneus in 122 patients of the same age group with cadavers were radiologically measured. Maximum length, maximum width, maximum height, $B{\ddot{o}}hler$ angle, Gissane angle, Fowler-Phillip angle, and tala-articular angle were measured. Results: In cadaveric measurement, the mean maximal height, length, and width were $41.8{\pm}3.3mm$, $73.3{\pm}3.4mm$, and $40.7{\pm}2.2mm$, respectively. In radiological measurement, the mean maximal height, length, and width were $38.5{\pm}4.3mm$, $74.0{\pm}5.7mm$, and $44.7{\pm}1.4mm$, respectively. In cadaveric measurement, the mean $B\ddot{o}hler$ angle, Gissane angle, Fowler-Phillip angle, and tala-articular angle were $32.1^{\circ}{\pm}6.2^{\circ}$, $110.8^{\circ}{\pm}8.1^{\circ}$, $55.8^{\circ}{\pm}6.8^{\circ}$, and $59.7^{\circ}{\pm}4.6^{\circ}$, respectively. In radiological measurement the mean $B{\ddot{o}}hler$ angle, Gissane angle, Fowler-Phillip angle, and tala-articular angle were $32.6^{\circ}{\pm}3.8^{\circ}$, $113.7^{\circ}{\pm}5.7^{\circ}$, $62.2^{\circ}{\pm}3.9^{\circ}$, and $61.6^{\circ}{\pm}6.3^{\circ}$, respectively. The mean maximal height was significantly higher in the cadaveric measurement group (p<0.001) and the mean maximal length and width were significantly higher in the radiologic measurement group (p<0.001, p<0.001). The mean Gissane angle, Fowler-Philip angle, and $B{\ddot{o}}hler$ angle were significantly higher in the CT group (p=0.001, p<0.001, p=0.016, respectively). There was no significant difference in the mean tala-articular angle (p=0.352). Conclusion: Significant differences in length parameters were observed between the cadaveric measurement group and the radiologic measurement group. However, no significant differences in angular measurements were observed between the two groups. The authors carefully conclude that radiological measurement values may be different from actual values in the calcaneus.

Existing Intra-oral radiography examinations have problems with information on the angle of incidence used in textbook and those used in the field, and radiologic examinations result vary depending on the operator's skill. Therefore, this study aimed to suggest an ideal angle of incidence for radiological examination so that the proximal areas between teeth are clearly visible without overlapping. First, patient's dental arch in the exact center, and the angle of incidence of the point where the teeth did not overlap was measured using a protractor tool in program. Second, based on the calculated results, we surveyed patient phantoms for student practice during Intra-oral radiography examination and conducted a survey based on qualitative evaluation using a 5-point Likert scale.When comparing the average value obtained by measuring actual patient data and the angle specified in the existing reference book, there is a statistically significant difference in the average between the two groups at p < 0.05 in the proximal area of all teeth, and even if the gender and age group are different, there is a significant difference. Because it did not deviate from the scope, we were able to obtain results that could be sufficiently presented as guidelines. In addition, in a qualitative evaluation based on the images presented by applying the actual measured data to the phantom, images were obtained in which the adjacent surfaces of teeth do not overlap. In conclusion, this study proposes guidelines for the angle of incidence during Intra-Oral Radiography examination to reduce cone-cut images or images with overlapping proximal area and prevent repeat.

Purpose: The aim of this study was to compare the short-term operative outcomes of laparoscopy-assisted total gastrectomy (LATG) with those of open total gastrectomy (OTG) for patients suffering with advanced upper gastric cancer. Materials and Methods: Of the 47 patients who underwent LATG with $D1+{\beta}$ or D2 lymphadenectomy from July 2004 to March 2008, 29 patients with pathologically proven advanced gastric cancer were compared with 35 patients who underwent conventional OTG during the same time period. The comparison was based on the clinicopathological characteristics, the surgical outcome, the follow-up survival and tumor recurrence. Results: The patients' age, gender and body mass index were similar between the two groups. However, there were statistically differences in tumor size ($9.2{\pm}3.9$ vs $6.1{\pm}3.6cm$, P=0.002) and the proximal resected margin ($2.1{\pm}2.0$ vs $3.6{\pm}2.1cm$ P=0.004). There was no significant difference in most of the peri- and post-operative courses such as the time to first flatus, the time to starting a solid diet and the length of the hospital stay, except for a longer operating time (289.0 vs. 361.3 minutes, P<0.001) in the LATG group. The complication rate was higher in the LATG group (13.8%) than that in the OTG group (5.7%). The mean overall survival and disease free survival times were 32 and 31 months, and 24 and 28 months, respectively, with an average 18.8 months follow-up duration. The main recurrent sites were peritoneum and lymph node in both groups. Conclusion: The early results of the current study suggest that LATG for AGC is technically feasible and it does not show any inferiorities of the postoperative outcomes as compared to those of conventional open total gastrectomy.
