In this paper, we study a directed simple graph ${\Gamma}_S(N)$ for a near-ring N, where the set $V^*(N)$ of vertices is the set of all left N-subsets of N with nonzero left annihilators and for any two distinct vertices $I,J{\in}V^*(N)$, I is adjacent to J if and only if IJ = 0. Here, we deal with the diameter, girth and coloring of the graph ${\Gamma}_S(N)$. Moreover, we prove a sufficient condition for occurrence of a regular element of the near-ring N in the left annihilator of some vertex in the strong zero-divisor graph ${\Gamma}_S(N)$.

Psoas compartment block has been used to provide anesthesia and analgesia of hip joint. This block is advocated for relief of pain of various origins in the thigh, leg and lumbar area. A-40-year-old women complained of pain in the left thigh and lumbar area after operation of the second lumbar vertebral compression fracture. To relieve pain, caudal block was performed. This block reduced in lumbar pain but left thigh pain persisted. So, we were performed psoas compartment block using mepivacaine and dexamethasone, which relieved the pain in the left thigh and lumbar area. We recommend psoas compartment block as useful and simple method for patients with thigh and lumbar area pain, especially when the epidural block is not feasible.

Cor triatriatum is rare congenital heart disease which is another variant of anomalous pulmonary venous return. It has abnormal fibromuscular diaphragm between true left atrium and accessary chamber which has one or more orifice to the left atrium. In classic form, the patient dies within several months after birth due to pulmonary hypertension inevitably, so it is rarely found in adult. With priopertive echocardiogram and cineangiogram we had two impressions, left atrial cystor cortriatriatum. At operative finding, there was no visible combined anomaly except accessary chamber which received all pulmonary venous return that drained into the left atrium through small calcified orifice. The operation was performed by simple resection of the diaphragm under cardiopulmonary bypass. The postope rative course was uneventful.

We give some properties of intuitionistc fuzzy left, right, and two-sided ideals and bi-ideals of a semigroup. And we characterize a regular semigroup, a semigroup that is a lattice of left(right) simple semigroups, a semigroup that is a semilattice of left(right) groups and a semigroup that is a semilattice of groups in terms of intuitionistic fuzzy ideals and intuitionistic fuzzy bi-ideals.

Purpose: In an amputated auricle, a microvascular anastomosis is the best treatment of choice. But, the neartotally amputated auricle which is connected by very narrow tissue pedicle to the head, can survive by simple attachment without a microvascular anastomosis owing to the rich vascular network through the superficial temporal artery and posterior auricular artery. In cases of venous congestion resulting from a lack of vein anastomosis, medical leeches (Hirudo medicinalis) can solve the problem. We are reporting the case of a 6-year-old boy who had a neartotally amputated auricle with successful results by simple closure and medical leech treatment without a microvascular anastomosis. Methods: A 6-year-old male patient had an left auricular injury by an escalator accident. The left auricle was neartotally amputated from the temporal head with connection only by very narrow skin and subcutaneous pedicle (about 1 cm in width) at the helical root of upper and anterior part of auricle. Marginal bleeding from the avulsed auricle was noted and the arterial blood was supplied from a branch of upper auricular branch of the superficial temporal artery. The auricle was repaired by simple closure including cartilage and skin without any vascular anastomosis. After simple closure, the auricle showed good circulation with pink color. But on the 2nd day after the operation, there was a venous congestion with severe swelling, which resulted in a purplish colored auricle. The venous congestion disappeared after using medical leeches by the 5th day after the operation. Results: The repaired auricle showed aesthetically and functionally satisfactory result with normal development at the 9 months follow-up check after the operation. Conclusion: In cases of neartotally amputated auricles of children or crushing injury in which microsurgery is difficult, we can try simple closure with the use of medical leeches in treating a of venous congestion for a successful result.

It is widely known that language functions in our brains are lateralized to the left hemisphere and spatial recognition functions are lateralized to the right hemisphere. It is also known that handedness is closely related to the lateralization of brain functions. However, at what point in the brain‘s development the lateralization of brain functions takesplace is still disputed. This study sought to find differences in linguistic and spatial abilities between left-handed and right-handed children, and provide objective data on the relationship between the handedness and the brain lateralization. 19 left-handed children and 20 right-handed children aged 5 were chosen through questionnaire for this study and the K-WPPSI simple intelligence test was used to check the homogeneity of two groups. The results showed that the differences inlinguistic and spatial ability between left and right-handed children were not statistically significant.

Casting specimens of portal system and hepatic vein system in livers were made by injection of vinylite into the portal vein and postcava in 20 adult dogs. The author classificated the ramification of portal system and hepatic vein system. The results obtained were summerized as follows: 1. Portal system in livers were divided into left and right trunks. The left trunk subdivided into papillary process (caudate lobe,) left medial lobe, left lateral lobe, quadrate lobe and right medial lobe rami. The right trunk were subdivided into right lateral lobe and caudate proccss(caudate lobe.) 2. The lateral superior and medial inferior rami of portal system in left lateral lobe were subdivided 1 or 2 branches from left trunk. 3. The lateral superior ramus of portal system in left medial lobe did not appeared in 40% of the cases examined. 4. Portal system in quadrate lobe were subdivided 1-3 branches from left trunk, 5. Portol system in right medial lobe rami were relatively simple in ramification. 6. The lateral superior and medial inferior rami of portal system in right lateral lobe were subdivided 1 or 2 branches from right trunk. 7. Hepatic vein system of left lateral, left medial, quadrate and right medial lobe rami were originated from same ramus divided from the postcava in all cases. 8. Hepatic vein system of left and right rami in right medial lobe were divided from postcava.

Congenital diaphragmatic hernia remains a disease with high neonatal mortality rate despite recent advance in neonatal intensive care. We experienced one case of the congenital diaphragmatic hernia with acute respiratory distress and left pulmonary hypoplasia in the neonate. The simple closure was performed through left paramedian approach after diagnosis. The postoperative course was uneventful except wound disruption. The patient was follow-up with good general condition.

According to the paper in [3], the kernel of an ordered semigroup S is a completely regular subsemigroup of S. In this note we show that the kernel of an ordered semigroup S is not a completely regular subsemigroup of S, in general.

Video thoracoscopic surgery is a new modality that gains acceptance rapidly from thoracic surgeons. We have experienced two left lower lobectomies, one left upper lobectomy & one right upper lobectomy with using video thoracoscopy for the four patients with lung parenchymal disease from July 1992 to February 1993. The post-operative courses were uneventful. The final pathologic diagnosis were sclerosing hemangioma, adenocarcinoma, bronchiectasis, leiomyoma & the post-operative courses were short. These patients needed less analgesics because postoperative pain was reduced markedly, and hospitalization was shortened due to rapid recovery. We would like to prefer video thoracoscopic lobectomy to the lobectomy through standard thoracotomy in uncomplicated patients with simple pulmonary parenchymal diseases.
