Aminated oilve oil derivative as the new organic disperse phases of the water soluble metal working fluid has been synthesized and tribological properties of the aqueous solutions composed of aminated olive oil derivative investigated using Four Ball Wear Tester and Falex EP Tester. The formulated aqueous solutions showed higher antiwear and extreme pressure properties and also lower friction coefficient. On the basis of the the results, water soluble aminated oilve oil derivative showed excellent tribological properties due to the polarizability of oleic acid derivative composed of majority part in oilve oil.

A vertical skin incision with median sternotomy for open heart surgery usually leaves an unsightly hypertrophic scar, and it makes cosmetic and psychic problems especially in young female patients. Since November 1986, we have used a bilateral submammary skin incision with dissection of a fasciocutaneous flap in 5 young female patients with uncomplicated acyanotic congenital heart disease. The exposure of the operative field was excellent. And we had good results without any significant complication associated with this type of incision.

For many years a wide variety of surgical techniques for closure of cleft lip has been used. Still many surgeons prefer the Millard's rotation-advancement lip repair because the surgical scar is masked in the philtral crest and the nostril floor, and it improves the relationship of the alar base of the cleft side, producing harmonious symmetry of the nostril and the nostril sill. In addition, it uses and preserves the lip anatomy, returning lip tissue into its normal position, minimizing the amount of tissue that is discarded, and reconstructing the orbicular oris muscle. One of the major disadvantages of this procedure is the lack of accurate measurements. The object of this study is to help in the cleft lip surgery with investing its features and design.

Objective : Epidural fibrosis and adhesion are the main reasons for post-laminectomy sustained pain and functional disability. In this study, the authors investigate the effect of irradiated freeze-dried human amniotic membrane on reducing epidural adhesion after laminectomy on a rat model. Methods : A total of 20 rats were divided into two groups. The group A did not receive human amniotic membrane implantation after laminectomy and group B underwent human amniotic membrane implantation after laminectomy. Gross and microscopic findings were evaluated and compared at postoperative 1, 3 and 8 weeks. Results : The amount of scar tissue and tenacity were reduced grossly in group of rats with human amniotic membrane implantation (group B). On a microscopic evaluation, there were less inflammatory cell infiltration and fibroblast proliferation in group B. Conclusion : This experimental study shows that implantation of irradiated freeze-dried human amniotic membrane reduce epidural fibrosis and adhesion after spinal laminectomy in a rat model.

This is a case report of surgically treated esophageal traction diverticulum which was resulted from postpneumonectomy empyema. In March, 1976, left lower lobectomy and thoracoplasty were performed at a hospital to treat long standing lung abscess, after operation it developed into empyema. One year later [April, 1977], We did decortication and left upper lobectomy[ultimate pneumonectomy], which was followed by empyema again, 3 months later it developed esophagopleurocutaneous fistula. Esophagograms bowed an adult thumb tip sized traction diverticulum in the midportion of the esophagus. Finally in January, 1978, after 6 months of gastrostomy feeding, fistulectomy and diverticulectomy were performed The funnel shaped diverticulum was in midesophagus and retracted by surrounding inflammatory scar tissue. Now the postoperative course was uneventful.

The effect of author's recipe of milk-substituting food was studied on 164 children of a primary school. Dividing the subjects into tow groups, A and B respectively, the former being fed with the author's food and the latter served as control, feeding was continued for 6 months daily at lunch hour, with the following results. (1) The effect of the author's milk-substituting food on the body-physique of the children could not be evaluated because of the short period of observation. (2) As observed clinically, various nutritional deficiency symptoms, such as anemia, angular scar glossitis, and hyperkeratosis, were far less frequently occurred in the fed group, while no such significant reduction of occurrence was noted in the control group. It was concluded from the above results that the well-balanced school feeding to the children Is necessary.

Ideal results of augmentation mammaplasty consist of symmetry, natural shape, soft feeling and inconspicuous scar. In addition, patient's preferences about size and shape should be included. Static implants could not perfectly satisfy patients' desires for size and shape, but expandable implants enable to change the volume after the operation. From September 2001 to September 2004, 76 patients(150 breasts) underwent breast augmentation using permanent expandable implant. The procedure was unilateral in 2 women and bilateral in 74 women. Age ranged from 19 to 50 years(mean, 29 years). Fifty nine patients underwent simple augmentation mammaplasty, 7 patients were corrected of their severe asymmetry, 2 patients with the congenital breast deformity underwent mammaplasty using this, and 2 patients who had undergone unilateral mastectomy were reconstructed of their breasts using expandable implant. There were no definite complications such as capsular contracture, implant rupture, asymmetry. And there reported little dissatisfaction about the size. The permanent expandable implants might be good alternatives in cases of ordinary breast augmentation as well as tissue deficient patients, asymmetry, congenital anomaly, and breast reconstruction.

Purposes of this research are convenience of manufacture, quality sophistication and reduction of a/s' ratio by that improve several shortcomings of existing steel housing The Housing of head is changed existent steel housing to ABS (acrylonitrile butadiene styrene) copolymer housing and its shape is changed. It does not need that paint housing by paint. so We may not care scar at storage or manufacture. The fast work speed and A/S is possible by combining a safety plate and a housing by volt and spring washer. When disjoint head part, there is no damage of safety plate and housing. Noise is disappeared by resonance phenomenon in early rpm at motor moving. When neck part of housing and a middle pipe are connected by drill nasa, the work is easier Also, there is sense of security little more catching motor in housing The improvement accomplished much improvements including light weight of head part.

Urinary tract infection (UTI), the most common bacterial disease in childhood, is frequently associated with urinary tract anomalies (15-50%) and can induce renal scarring, which is a cause of hypertension and chronic kidney disease. Despite the high risk of renal scarring in infancy, the diagnosis may be delayed due to its nonspecific presenting symptoms; moreover, over-diagnosis is frequent due to the contamination of urine samples. The delay in diagnosis and treatment may induce sepsis or renal scar, while over-diagnosis is responsible for unnecessary antibiotic treatment and costly urinary imaging studies. UTI guidelines have been ever-changing for the past three decades, but some controversial issues remain. This article is a revision of the previous KSPN (Korean Society of Pediatric Nephrology) guideline and addresses the recent controversies concerning childhood UTI.

Purpose: This study aimed to evaluate the usefulness of the needle aspiration alternative to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage. Methods: From January 1998 to June 2008, we retrospectively reviewed 38 children treated with needle aspiration as management with suppurative cervical lymphadenitis instead of open surgical drainage. Results: All 38 children underwent only 1 puncture. Two patients (5.2%) out of 38 patients experienced reformation of an abscess and all recovered completely after re-treatment with antibiotics. Minor complications were detected in 2 patients (5.2%). One complication originated from remnant necrotic tissue and the other involved formation of a small scar in two patients, which resolved spontaneously. There were no major complications. Conclusion: Needle aspiration can be a simple, safe, and effective alternative procedure to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage.
