Purpose: The purpose of this study was to evaluate the importance and the performance of intramural marketing in the hospital and to examine the effect of intramural marketing on nurses' job satisfaction and turnover intention. Method: The participants of this study were 203 nurses, who had worked over 3 months in the general or special units in C university hospital located in Seoul. Results: The participants' perceived performance of the intramural marketing was 2.35 on average. The importance of the intramural marketing recognized by the participants was 4.02. The score of the job satisfaction of the participants was 2.74 and that of the turnover intention was 3.67 on average. The intramural marketing demonstrates statistically significant correlations with job satisfaction and turnover intention. Conclusion: The findings of the study demonstrate the importance of the intramural marketing in the hospital for nurse retention. In order to increase nurses' job satisfaction and reducing their turnover intention, the intramural marketing activities should be expanded further.

Spontaneous intramural hematoma is a rare complication of oral anticoagulants, and its incidence is expected to increase because of the increasing number of elderly patients undergoing anticoagulant therapy. Clinical manifestations of spontaneous intramural hematoma vary from mild abdominal pain to intestinal obstruction or acute abdomen. Early diagnosis is important because most patients can be treated successfully without surgery. The role of endoscopy in the diagnosis of intramural hematoma is not well established because almost all cases are diagnosed non-invasively with computed tomography scans. However, confirmation of the intramural hematoma through direct visualization of the involved bowel mucosa is helpful, if the imaging diagnosis is uncertain. We report a case of anticoagulant-induced spontaneous intramural hematoma, which was diagnosed using endoscopy, with relevant literature review.

We experienced a female patient with intramural hematoma of the aorta. This patient had a severe anterior chest pain radiating to interscapular area with choking sensation. CT revealed a intramural hematoma of the thoracic aorta and a part of the abdominal aorta but there was no evidence of intimal tearing. We did the eme gency operation under hypothermic circulatory arrest and retrograde cerebral perfusion. Ascending aorta was replaced and coronary artery bypass graft was done because of intimal tearing of the ostium of right coronary artery. She was discharged without any significant complication. We reported this case with consideration about necessity of emergency operation for intramural hematoma of the thoracic aorta.

Duodenal injury following blunt abdominal trauma is a relatively unusual complication, and it may sometimes be difficult to distinguish a duodenal hematoma from duodenal perforation. According to recent reports, intramural hematomas typically resolve spontaneously with conservative treatment. Surgery, however, is occasionally necessary in some cases if the diagnosis is delayed, conservative therapy fails, or a high degree of suspicion of duodenal injury persists. We experienced a case of delayed manifestation of a duodenal intramural hematoma that was surgically treated.

Mitochondria are cytosolic organelles essential for generating energy and maintaining cell homeostasis. Despite their critical function, the handful of proteins expressed by the mitochondrial genome is insufficient to maintain mitochondrial structure or activity. Accordingly, mitochondrial metabolism is fully dependent on factors encoded by the nuclear DNA, including many proteins synthesized in the cytosol and imported into mitochondria via established mechanisms. However, there is growing evidence that mammalian mitochondria can also import cytosolic noncoding RNA via poorly understood processes. Here, we summarize our knowledge of mitochondrial RNA, discuss recent progress in understanding the molecular mechanisms and functional impact of RNA import into mitochondria, and identify rising challenges and opportunities in this rapidly evolving field.

Intramural pregnancy is an unusual ectopic gestation located within the uterine wall, completely surrounded by myometrium and separate from the uterine cavity, fallopian tube, or round ligament. It is known to be difficult to diagnose, and associated with a high rate of uterine rupture. We report a case of intramural pregnancy in which early diagnosis was made and successful treatment was done by dilatation and curettage. Diagnostic laparoscopy confirmed the absence of uterine rupture during the procedure. Therefore, conservation of fertility can be possible with early diagnosis of intramural pregnancy. To our knowledge, this is the first case report of intramural pregnancy following IVF-ET in Korea.

Intramural esophageal dissection is a rare disorder that's characterized by a lengthy laceration between the mucosal and submucosal layers of the esophageal wall, and the esophageal wall is without perforation. The three different types of acute esophageal injury are a mucosal tear (Mallory-Weiss syndrome), full-thickness rupture (Boerhaave's syndrome) and intramural esophageal dissection. Most intramural esophageal dissections respond to conservative management with a very good prognosis. This rare condition should be considered in patients who present with acute chest pain, dysphagia or odynophagia, and particularly in the presence of a bleeding disorder or where there has been recent administration of antiplatelet medication, anticoagulantsorthrombolyticsto avoid inappropriate treatment with surgery. We present here a rare case of intramural dissection of the esophagus that occurred when the patient was taking anti platelet medication.

A pulmonary artery periadventitial hematoma is a rare complication of a Stanford type A intramural hematoma. As the proximal ascending aorta and pulmonary artery share a common adventitial layer, extravasated blood from the intramural hematoma in the ascending thoracic aorta may extend to beneath the adventitia of the pulmonary artery. The authors describe a case involving a 66-year-old male with acute chest pain who presented with a pulmonary artery periadventitial hematoma associated with a Stanford type A intramural hematoma.

Background: The intramural coronary artery has been known as a risk factor for early death after an arterial switch operation (ASO). We reviewed the morphological characteristics and evaluated the early and mid-term results of ASO for patients with an intramural coronary artery. Materials and Methods: From March 1994 to September 15th 2010, 158 patients underwent ASO at Dong-A and Pusan National University Hospitals for repair of transposition of the great arteries and double outlet right ventricle. Among these patients, 14 patients (8.9%) had an intramural coronary artery. Mean age at operation was $13.4{\pm}10.2$ days (4 to 39 days) and mean body weight was $3.48{\pm}0.33$ kg (2.88 to 3.88 kg). All patients except one were male. Eight patients had TGA/IVS and 4 patients had an aortic arch anomaly. Two patients (14.3%) had side-by-side great artery relation, of whom one had an intramural right coronary artery and the other had an intramural left anterior descending coronary artery. Twelve patients had anterior-posterior relation, all of whom had an intramural left coronary artery (LCA). The aortocoronary flap technique was used in coronary transfer in 8 patients, of whom one patient required a switch to the individual coronary button technique 2 days after operation because of myocardial ischemia. An individual coronary button implantation technique was adopted in 6, of whom 2 patients required left subclavian artery free graft to LCA during the same operation due to LCA injury during coronary button mobilization and LCA torsion. Results: There was 1 operative death (7.1%), which occurred in the first patient in our series. This patient underwent an aortocoronary flap procedure for coronary transfer combining aortic arch repair. Overall operative mortality for 144 patients without an intramural coronary artery was 13.2% (19/144). There was no statistical difference in operative mortality between the patients with and without an intramural coronary artery (p>0.1). There was no late death. The mean follow-up duration was $52.1{\pm}43.0$ months (0.5 to 132 months). One patient who had a subclavian artery free graft required LCA stenting 6.5 years after surgery for LCA anastomotic site stenosis. No other surviving patient needed any intervention for coronary problems. All patients had normal ventricular function at latest echocardiography and were in NYHA class 1. Conclusion: The arterial switch operation in Transposition of Great Arteries or Double Outlet Right Ventricle patients with intramural coronary can be performed with low mortality; however, there is a high incidence of intraoperative or postoperative coronary problems, which can be managed with conversion to the individual coronary button technique and a bypass procedure using a left subclavian free graft. Both aortocoronary flap and individual coronary button implantation techniques for coronary transfer have excellent mid-term results.
