CT has become the most useful, non-invasive diagnostic method as the initial exmination in the diagnosis ofruptured intracranial aneurysm with intracranial hemorrhage(subarachnoid, intracerebral and intraventricularhemorrhage), hydrocephalus and infarction. Furthermore, high resolution CT can demonstrate aneurysm itself. Butangiography is the last and conclusive method as yet, for better evaluation of vascular anatomic structure ofaneurysm for surgery. Authors analyzed 40 cases of ruptured intracranial aneurysm confirmed by CT, angiographyand/or surgery at Chonnam National University Hospital from July, 83' to July, 85'. The results were as follows:1. The most prevalent age group was the 5th decade(35%), and female patient(57.5%) was more comon than male. 2.Angiographic findings were as follows: 1) Multiple aneurysm was found in 8 patients (20%): the one of thesepatients is tripple, the others are double. 2) The location of aneurysm, in order ot frequency, were : ACA andA-com aneurysm in 23 cases(47%). ICA and P-com aneurysm in 17 cases(35%), basilar tip aneurysm in 4 cases(8%), MCAaneurysm in 3 cases(6%) and PCA aneurysm in 1 case(2%). 3) Hydrocephalus was detected in 22 cases (55%): 21 cases(95%) of these cases were demonstarated within the first 3 weeks after attack. 4) Detection of aneurysm itseslfwas 20 cases(50%). 5) Cerebral infarction was 5 cases(12.5%). 6) Subarachnoid enhancement on post-contrast scanwas 8 cases(20%).

Purpose: The purpose of this study was to investigate the effect of motivational regulation strategies (MRSs) on cognitive learning and academic performance. Methods: The participants were a total of 510 pre-medical and medical students. Survey instruments assessed the use of MRSs and cognitive learning strategies. Students’ grade point averages were used for academic performance. Structural equation modeling was used to analyze data, using Mplus ver. 7.4 (Muthén & Muthén, Los Angeles, USA). Results: Confirming the measurement model validity, the results of structural model indicated the followings: (1) MRSs had a significant impact on cognitive learning, while these strategies negatively affected academic performance; (2) cognitive learning significantly influenced academic performance and mediated the effect of MRSs on academic performance; and (3) only academic levels had a significant effect on cognitive learning. Conclusion The findings from this study confirmed that MRSs were highly influential to predicting students’ cognitive learning which affects their better learning performance. Thus, instructional design and practice to support learning motivation is needed to promote cognitive learning and training programs to practice the effective methods of using MRSs in learning need to be provided.

Due to the coronavirus disease 2019 pandemic, the new norm of online learning has been recognized as core to medical institutions for academic continuity, and students are expected to be motivated and engaged in learning while maintaining distance from other peers and educators. To facilitate students’ and educators’ newly defined roles in online medical education settings, it is crucial to understand how students are actively motivated and engaged in learning. Hence, this study explored medical students’ motivational regulation profiles and examined the effects of motivational regulation strategies (MRS) on cognitive learning and learning engagement for online learning. Data were collected after the end of the first semester in 2020 from a sample of 334 medical students enrolled at a public university school of medicine. Latent profile analysis indicated three subgroups with different motivational regulation profiles: the low-profile, medium-profile, and high-profile groups. Regarding different MRS patterns in the high-profile group, mastery self-talk, performance approach self-talk, and the self-consequating strategy appeared to be most applicable for regulating learners’ motivation. Analysis of variance showed that the profile groups with higher levels of MRS use were connected to a higher willingness to use cognitive learning strategies and a higher degree of engagement in online learning. The findings of this study emphasize the use of specific sets of MRS to support learning motivation and the need to design effective self-regulated learning environments in online medical education settings.

PURPOSE: The purpose of this study is to analyze left ventricular (LV) radial strain (S) and strain rate (SR) in children with dilated cardiomyopathy (DCM) and to evaluate whether the impairment of global radial wall motion correlates with global ventricular dysfunction in DCM. METHODS: In 10 DCM patients (range 0.6-15 years, median age 6.5 years, 3 females) and 17 age and sex matched normal controls (range 0.5-14 years, median age 5 years, 5 females) conventional echocardiography and real time tissue Doppler imaging analysis were performed. Using an automatic two dimensional speckle tracking imaging (STI) method radial S and SR were calculated for each LV segment in 18 segment model. To evaluate the correlation between the impairment of radial motion and LV global function, the average values of radial S and SR of each LV level were obtained, and defined as global (G) S or SR. RESULTS: LV radial S and SR were markedly heterogeneous and decreased in almost all segments of LV in DCM. Impaired radial S and SR were associated with global LV dysfunction. CONCLUSION: In DCM, decreased and disorganized radial S and SR contribute to LV dysfunction. Analysis of radial S and SR with STI method can give further information on LV function in DCM.

PURPOSE: Gall bladder (GB) stones in children are rarely observed, and so reports of them have been quite limited in Korea. Therefore, we tried to assess the epidemiology and clinical features of children with GB stone diagnosed at Severance Hospital. METHODS: A clinical study was performed on 18 patients below 15 years of age diagnosed with GB stone by abdominal ultrasonography or CT scan at Severance hospital from January 1999 to May 2005. RESULTS: Concerning patients' profile, their sex ratio of male to female in total 18 cases was 2:1 with the mean age of 6+/-4.3 years. 15 patients (83.3%) were asymptomatic. Inducing factors were found in 14 children (77.8%) including ceftriaxone therapy in 6 cases (33.3%), infection in 4 cases (22.2%), spherocytosis in 3 cases (16.7%), Down syndrome and abdominal operation in 1 case (5.6%) respectively. Single stone was found in 13 cases (76.5%) and multiple in 4 cases (23.5%). 15 cases (88.2%) had the stones less than 5 mm in size, and 2 cases (11.8%) between 5 and 10 mm. 17 patients received conservative treatment, and one patient had cholecystectomy due to Meckel diverticulum. CONCLUSION: In this report, Pediatric GB stones are predominant in male children, without typical symptoms, having inducing factors, single and small. Recently the diagnosis of them has been increased because of the development of imaging study. But the reports for them were still rare in Korea. Therefore the study for them is more necessary to find it's clinical characteristics.

Medicolegal autopsy is a vital tool for obtaining reliable injury mortality data. This study statistically analyzed data obtained from medicolegal autopsies performed in Korea in 2013. The aim of this study was to analyze various aspects of the 4,861 deaths that were categorized as unusual in Korea in 2013. A total of 4,861 deaths were analyzed by gender, age, manner of death, and cause of death. Of the 4,861 deaths, 3,542 (73.3%) were of men and 1,302 (26.7%) were of women. With respect to the manner of death, 54.4% were recorded as unnatural deaths, 38.8% were natural deaths, and 6.9% had unknown causes. Of the 2,642 unnatural deaths, 45.0% were determined to be accidental deaths, 26.3% suicidal, 16.9% homicidal, and 11.8% undetermined. Of the total number of unnatural deaths, 42.1% were trauma-related deaths, for which falling down accounted for 33.8%. Asphyxiation accounted for 16.0% of unnatural deaths, and of these, the predominant cause was hanging (58.8%). In addition, 14.4% of deaths were due to drowning, 12.9% poisoning, 11.0% thermal injuries, 1.8% complications arising from medical procedures, and 0.8% electrocution, starvation, or neglect. Among the 1,886 natural deaths, heart diseases accounted for 52.0% and vascular diseases accounted for 16.9%. Of the 196 deaths among children under the age of 10 years, 41.8% were recorded as unnatural deaths, 45.1% were natural deaths, and 1.5% had unknown causes.

During ten years from Mar. 1973 to Feb. 1982, 2410 amputations of limbs have been experienced in Korea Veterans Hospital. 240 painful neuromas, which developed in 203 amputated limbs of 191 patients were treated with four different methods 1) Stretching and simple transection, 2) Transection and ligation, 3) Ligation and absolute alcohol injection and 4) Implantation into bone. After following up for average 5 years and 7 months, the following results were obtained. 1. The painful neuroma occured in 191 (7.9%) out of 2410 amputees. 2. The painful neuroma developed averege 2 years and 9 months after the first amputation. 3. After transection and ligation of the nerves, the painful neuroma recurred in 19.2% of the cases. The average interval taken to recur was 2 years and 6 months. 5. After ligation and absolute alcohol injection into the nerves, the painful neuroma recurred in 14.8% of the cases. The average interval taken to recur was 2 years and 6 months. 6. After implantation of the nerve into the bone, the painful neuroma recurred in 5.7% of the cases. The average interval taken to recur was 2 years and 2 months. 7. The best results were obtained after implantation of the nerves into the bone.
