Two groups of left pulmonary-subclavian artery anastomosis were done in 26 adult mongorel dogs. For the first group. the distal end of the subclnvian artery was nnastomosed to the side of the left pulmonary artery, and for the second group, the subclavian end wns anastomosed to the proximal end of the left lower lobe pulmonary artery. Among them, 6 died of bleeding or anesthetic failure during the day of operation, 10 survived 1 to 106 days and the other 10 were sacrificed at various interval. To investigate the relationship between hemodynamic stress and temporal evolution of the pulmonary vascular lesions. the pulmona try and femoral artery pressures, arteriogram and pathohistological specimens were obtained. The following results were obtained. 1. The postoperative pulmonary artery pressures were within normal limits except 2 dogs in the first group, but in nil 12 dogs of the second group, they were in moderate to maked pulmonary hypertension level. 2 After subclavian pulmonary anastomosis, both groups dogs showed increased femond artery pulse pressure. 3. The pulmonary vascular changes were more severe and appeared earlier in the second group dogs compared with the first group.4. The earliest vascular changes appeared in the media of the small muscular arteries and arterioles. 5. Various vascular chaDges were produced in 2 or 3 months. Thereafter, the changes were stationary. 6. Among the first group, two long-term servivors (No. 705 & 713) which had normal pulmonary artery pressure under the anesthesia, also showed various vascular changes as other pulmonary hypertensive dogs. 7. In the early stage medial hypertrophy. interruptio~l of elastic lamellae were found in the small muscular arteries and arterioles, which were followed by intimal proliferation and thrombosis. These findings may suggest some evidences of trauma to the vessels. 8. Pulmonary arteriograms showed irregularity of the intima of the large and medium sized arteries, abrupt ending of some of the small arteries and narrowing of the anastomosis.

Iatrogenic ureteral injury is a complication that can occur during a variety of pelvic or abdominal surgeries. The most frequent causes are gynecological ones, followed by colon and vascular surgeries. Management of ureteric injury depends on the time of diagnosis and the severity of organ damage. Injuries diagnosed intraoperatively should be treated immediately. Occasionally, intraoperative ureteral injury is overlooked, and symptoms of the late diagnosis of ureteral injury are usually nonspecific; therefore, the diagnosis is delayed for days or weeks postoperatively. Management of injuries diagnosed postoperatively is more complex. There are differing opinions on whether an initial conservative or immediate operative intervention is the best line of action. Delayed repair is suggested on the grounds that it will reduce inflammation and tissue edema. However, many authors are in favor of early repair, perhaps because tissue planes are easier to find before fibrosis becomes too dense. Ureteral injuries occurring at the level of the pelvic brim should be best managed with an end-to-end anastomosis, preferably around a ureteric stent. More distal injuries also should be ideally managed with an end-to-end anastomosis, after excision of the crushed or compromised segments. However, if the remaining distal segment is short, ureteral reimplantation is the procedure of choice. The Boari flap technique for ureteral reimplantation is invaluable in cases with a short proximal segment. Delayed recognition of iatrogenic ureteral injury may be associated with serious complications, so prompt recognition of ureteral injuries is important. Recognition of the injury before closure is the key to easy, successful, and complications-free repair. Increased awareness of the risk for ureteral damage during certain operative maneuvers is vital to prevent injury, and to decrease the incidence of iatrogenic injury. A sound knowledge of abdominal and pelvic anatomy is the best prevention.

Purpose: Many studies on the time course of inducible nitric oxide synthase (iNOS) gene expression have been performed in the LPS (Lipopolysaccharide)-induced endotoxemic model, but there have been few experimental approaches to continuous peritonitis-induced sepsis model. We conducted this study to establish basic data for future sepsis-related research by investigating the time course of iNOS gene expression and the relationship with the production of inflammatory mediators in the early sepsis model induced by cecal ligation and puncture (CLP). Methods: Male Sprague-Dawley rats were operated on by sing the CLP method to induce of peritonitis; and then, they were sacrificed and samples of blood and lung tissues were obtained at various times (1,2,3,6,9 and 12 h after CLP). We observed the expression of iNOS mRNA from lung tissues and measured the synthesis of nitric oxide, $IL-1{\beta}$, and $TNF-{\alpha}$ from the blood. Results: iNOS mRNA began to be expressed at 3 h and was maintained untill 12 h after CLP. The nitric oxide concentration was increased significantly at 6 h, reached its peak level at 9 h, and maintained a plateau untill 12 h after CLP. $TNF-{\alpha}$ began to be detected at 3 h, increased gradually, and decreased steeply from 9 h after CLP. $IL-1{\beta}$ showed its peak level at 6 h after CLP, and tended to decrease without significance. Conclusion: We observed that the iNOS gene was expressed later in peritonitis-induced sepsis than in LPS-induced sepsis. Nitric oxide and key inflammatory mediators were also expressed later in peritonitis-induced sepsis than in LPS-induced sepsis.

Renal artery injury is a rare complication in blunt trauma, but can cause devascularization of the kidney, leading to renal failure. It requires early diagnosis and management. The treatment of renal artery injury still remains controversial, but recent studies have reported the successful treatment outcome with endovascular stent placement. Nevertheless, there is no standard treatment strategy in cases of pediatric patients. We report a case of a 16-year-old girl with right renal artery occlusion associated with a grade IV liver laceration. She was treated with only balloon angioplasty, and the kidney showed marked improvement of parenchymal perfusion with normalized renal function. Treatment with only balloon angioplasty can be a treatment option in pediatric patients with renal artery injury.

This study, approaching through view of Lacan and Althusser, is focused on conflicts and struggles concerning anniversaries in our society. August 15, Korean War, March 1 and Provisional Government are selected as subjects of the study, examining aspects of commemorative Struggle and changing process to those subjects. Means of the study are used through theories of Lacan and Althusser.The result of the study is analyzed that commemorative Struggle set up a starting point as the early modernization in the late 19th century. In other words, influence of modernization, which has been built up with a high hand though Japanese occupation, caused trauma and cracks. And this has been generated social conflicts, joining with ideology and fantasy. Converged point of this is Anniversary. If Anniversary and commemorative Struggle were inevitable to be existed as a phenomenon about social memory in the past, willpower heading to future should be reviewed through those days, to fill cracks of the society, not to return to the splitting past.

Objectives: Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study investigated the impact of maternal ACEs on PTSD in the offspring. Methods: A total of 156 mothers with children aged 13-18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. Results: Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). Conclusion: Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

Objectives: Childhood adversity is a risk factor for anxiety symptoms, but it affects anxiety symptoms in attention-deficit/hyperactivity disorder (ADHD). The current study aimed to examine the association between childhood adversity and anxiety symptoms in participants with and without ADHD. Methods: Data were obtained from a school-based epidemiological study of 1017 randomly selected children and adolescents. The ADHD and non-ADHD groups were divided using the Diagnostic Interview Schedule for Children Predictive Scale (DPS). The DPS was also used to assess comorbidities such as anxiety and mood disorders. The childhood adversities were assessed using the Early Trauma Inventory Self Report-Short Form, and the anxiety symptoms were assessed using the Screen for Child Anxiety Related Disorders. Linear and logistic regression models were used to investigate the association between childhood adversity and anxiety in the ADHD and non-ADHD groups with adjustments for age and sex. Results: This study found that the ADHD group did not show any significant association between anxiety symptoms and childhood adversities, whereas the non-ADHD group always showed a significant association. In a subgroup analysis of the non-ADHD group, the normal group without any psychiatric disorders assessed with DPS demonstrated a statistically significant association between childhood adversities and anxiety symptoms. These results were consistent with the association between childhood adversities and anxiety disorders assessed using DPS, as shown by logistic regression. Conclusion: The association between anxiety symptoms and childhood adversities statistically disappears in ADHD; ADHD may mask or block the association. Further longitudinal research is necessary to investigate this relationship.

Pelvic fractures are high-energy injuries, often accompanied by damage to the adjacent tissues and organs. For patients with pelvic trauma, active treatment is required early in the injury, because mortality can increase if appropriate treatment is not provided. In most cases, however, minimally invasive surgery is considered because extensive surgery cannot be performed due to the patient's condition. Percutaneous fixation of the pubis has been introduced because it can be applied easily to achieve the stability of the anterior part of the pelvis. Although many studies introduced percutaneous fixation of pubic bone fractures, most describe screw fixation for nondisplaced fractures. When treating displaced fractures with percutaneous screw fixation, it is difficult for the guide pin or drill bit to avoid the joint surface. Using a bent guide pin could allow easy insertion of the cannulated screw while avoiding the articular surface.

The education of children is one of the most important parts in children's literature. Children's literature, whose implied readers are both children and parents, is a good means to teach how they should behave and interact. Therefore, literary conventions of children's literature tend to be conservative with happy endings or fairy tale elements. Most of the children's literature of the 18th century were read as a conduct book which teaches children good manners and proper behavior, and at the same time served as a guidebook which tells parents how to discipline children. It emphasized the need of discipline to ascertain the hierarchy and order of the family, and cherished the close relationship between parents and children. In the 19th century, the ideal of family becomes more internalized. In the early 20th century, the ideology of family still remained, even though the world wars and economic depressions caused the cracks and collapses of the family. In the later 20th century, the disintegration of the traditional family was accelerated. The ideal of family based on the close relationship between parents and children, has had problems from the start. The attachment and over-closeness became stressful and sometimes could be poisonous. Recent children's literature shows the process of disintegration of the traditional nuclear family, children suffering in the fractured family, children's mental trauma, and nostalgia for the lost family. However, modern children's literature manages to find the lost or ideal surrogate family, and often shows fairy-tale elements such as mystical and heroic child protagonists or helpers who might solve all the difficult problems at once, despite the collapse of the family in reality.

Purpose: Cerebellar injury can be caused by a variety of factors, including trauma, stroke, and tumor. Cerebellar injury can manifest in different clinical symptoms and signs depending on the size and location of the injury. The purpose of this study was to examine and compare the recovery patterns of each motor function by tracking the motor levels of patients with cerebellar injury. Methods: This study recruited 11 patients with quadriplegia resulting from cerebellar injury. The motricity index (MI), modified Brunnstrom classification (MBC), and functional ambulation category (FAC) methods were used to evaluate motor levels. The motor function evaluation was performed immediately after the onset of the condition and at intervals of one month, two months, and six months after onset. Results: The MI values of the upper and lower extremities and hand function (MBC) indicated severe paralysis in the early stages of onset. Compared to the onset time, significant motor function recovery was observed after 1, 2, and 6 months (p < 0.05). In contrast, there was no significant pattern of recovery between 1, 2, and 6 months after onset (p > 0.05). FAC indicated showed significant recovery at one month compared to onset (p<0.05), and there was also a significant difference between 1 and 2 months (p < 0.05). On the other hand, there was no significant difference in FAC between 2 and 6 months (p > 0.05). Conclusion: Patients with cerebellar injury showed significant recovery in functions related to muscle strength and voluntary muscle control one month after onset and gradually recovered further over the next six months. On the other hand, gait function, which is closely related to balance, showed a relatively slow recovery pattern from the beginning of the disease to the six month follow-up.
