`Purpose: To study the use of acellular dermal allografts for the reconstruction of contracted anophthalmic sockets. Methods: A retrospective analysis was performed on 12 patients with contracted sockets who underwent reconstructive surgery using acellular dermal allografts from 2002 to 2006. Results: The mean age of the patients was 44.4 years. The mean duration of conjunctival sac contracture after removal of the eyeball was 21.4 years. In 4 patients, acellular dermal allografts were used as spacer grafts to elevate the eyelids, and in 8 patients the allografts were used as a conjunctival grafting material. All patients were able to wear ocular prostheses comfortably 2.2 months after surgery with acceptable cosmesis. There were no serious complications, such as infections or graft rejections during follow-up period. Conclusions: When used as conjunctival grafting materials and tarsal substitutes to elevate patients’ eyelids, acellular dermal allografts gave cosmetically and functionally acceptable results in the surgical rehabilitation of contracted sockets.`

Purpose: Visual loss secondary to inflammatory sinus diseases is an infrequent but disastrous complication. We analyzed the clinical features of patients with paranasal sinusitis who had signs of optic nerve dysfunction. Methods: Medical records of 10 patients (11 eyes), who presented with visual loss associated with inflammatory sinus diseases, were reviewed retrospectively. Results: The mean age was 53.7 years (range, 33-68 years). Involved sinuses were the sphenoid (10 eyes) and posterior ethmoid (7 eyes). The radiological evidence of orbital apex infiltration was shown in 8 eyes. Headache was the most common presenting symptom. The mean symptom duration before their first visit was 51.4 days. The underlying sinus pathology included fungal infection (5) and mucoceles (5). Fungal sinusitis and initially lower visual acuity were associated with poor visual prognosis, while mucocele showed good prognosis. Conclusions: The inflammatory sinus disease could leave a permanent visual deficit, especially in cases of fungal sinusitis and initially lower visual acuity. Multidisciplinary diagnostic and therapeutic approaches are essential to prevent serious ophthalmic complications such as permanent visual loss.

MDA(Model Driven Architecture)는 설계 모델을 점진적으로 변환시켜 복잡해지고 대형화되는 소프트웨어를 보다 효율적이며 효과적으로 개발 할 수 있는 기술이다. MDA에서는 모델 정보의 표현과 모델간의 정보 교환이 중요하며 이를 위해 OMG(The Object Management Group)에서는 XMI(XML Metadata Interchange)를 표준으로 제정했다. 이에 본 논문에서는 UML Class 정보를 XMI 문서로 변화해주는 XMI 변환 도구를 구현하고자 한다. 이것은 MDA 기반의 모델 변환에 관한 여러 연구들에 기반이 될 수 있을 것이다.

Laser cladding processing allows rapid transfer of heat to the material being minimum conduction into base metal. The effects of CO_2 laser cladding with high ?? powder were investigated. High viscosity bronze powder consists of bronze powder a?? used at a high temperature. The material has a high viscosity so that it can be e?? substrate. Therefore, Laser cladding can be processed on a curved or slope surface. CO_2 laser cladding was designed. It consists of the high viscosity bronze powder f?? the shielding gas system and the preheating system. The high viscosity powder properly at 0.35g/s and 0.50g/s. Because of the metallic bond between bronze powder the hardness of dilution layer was suddenly increased. Experimental as results in?? viscosity mixed powder can be a useful cladding material.

Although recent remarkable development of economic condition and improvement of living standard neonatal tetanus is still one of the serious problems in Korea, because of its relatively high incidence and mortality rate even with high skills and modern medicine. Prevention is the most important regimen so far. Author observed clinically total 28 cases of neonatal tetanus who were admitted to the Department of Pediatrics, Korea University Hospital from January 1974 to September 1978, at the same time, evaluated the effect of preventive program in a rural underprivileged area where deliveries usually performed in the homes by self-deliveries or by traditional birth attendants through the observation on the 22 cases of newly born infants. Preventive program against neonatal tetanus were carried cut on the base of education and equipment supply. Equipment supplied were simplest one autoclaving envelop containing an old mess blade (changed to small scissors later), a length of ligature and dressing. Education on care of the umbilical cord was undertaken for traditional birth attendants and mother and they were taught to use the equipment for cutting the cord and a sterile dressing. The following results were obtained. 1. The incidence of neonatal tetanus has not decreased during past 4 years and 9 months period annual admission was 6 cases as mean. 2. Sex incidence showed that male predominated in a ratio of 4.6: 1. 3. The majority of patients (85.7%) were 4 to 7 days of age on admission and peak incidence was noted at the age of 6 days (32.1%). 4. The most of the infants (92.8%) has had between 2,510gm to 4,000gm of body weight on admission and there was no evidence of higher incidence in low birth weight infant than others. 5. One third of the patients were lived in rural area and 2/3 were in urban. Twenty three of 28 patients (82.2%) were delivered at home, and 5 cases (17.8%) were at private clinics. 6. Many of them (71.4%) were used unsterilized home scissors to cut the umbilical cord, although boiled scissors or instruments were used in 6 cases. 7. The typical symptoms such as sucking failure (75.0%), convulsion (60.7%), irritability, trismus and fever were observed in most of the patients. 8. The majority of patients (64.3%) were stayed in hospital between 2 to 5 days and discharged to home against advice. Half of them were signed out on admission day or 2nd hospital day and all of them within 5th hospital day. Four cases who were stayed in hospital more than 20 days were all recovered completely and 3 cases were died within 8th hospital day. 9. Preventive program against neonatal tetanus in the rural underprivileged area by both the education and supply of simplest equipment for cutting the cord have been shown to be effective. During the period of this program, there were 22 cases of deliveries and no one had neonatal tetanus. First physical examination after birth showed only minor medical problems such as umbilical discharge, mild jaundice, thrush, loose stool, URI, skin and eye infections.

Ⅰ In general, in order to rasise the enterprise funds thereare two ways which one is a meant of internal funds and the other external funds. Then the principal way raising the enterprise funds is depend upon external funds, the way of which are also two ways through capital and financial market. But under the economic circumstance which the level of interest rates of banks are low, it can be considered to raise through the financial market as favorable method. In our real considered, the terms of borrowing are not only complicated but also it is impossible to raise a huge amount of funds all at once. So most enterprises are issuing the company bounds by means of raising a huge amount of funds at a tine, and goverment also is endevouring to promote issuing the bonds so as to improve financial structure and stabilize the raise of the bonds as well. Ⅱ 1. In Korea, the debenture issue is limited to three kind of bonds that is a guaranteed bond, a mortgage bond and convertible bond. 2. In case of floatation terms, long-term bonds are scarcely issuednand most of them short-term bonds which are due in 2 or 3years. 3. According to the current marketing system, stack exchange takes charge of it concentrically, andalso the organization an over-the-counter market isn't entirely formed. Ⅲ In these the rehause to organize and devleope the Korean deventure market will be summarized at: 1, Diversing of the bonds kind: The factors of investment inducement will be incfeased and moreover absorption of the bonds can be achieved smoothly as well as aromate the bond market and negotiability. 2. Flexibility and classification of the floatation terms Flexibility of the floatation terms harmonizes the bonds interests with the market interests and also fixation of the rate of interest, credit and profit of the issuer can be settled by the classification of the bonds. 3. Strengthening of an accepted function and the expansion of a security's size; Asorption of the bunds is dull in present situation. In order to solve this problem and prmote the bonds issue, establishment of an acceptance system must be settled first. Expansion of tile company related security and expanded supply of an accepting finance are required. 4. Development and organization of an over-the counter market; Smoothues of the bond circulation can be achieved by a stick exchange must take exclusive chrage of only a price formative function and a dispersive function assign to an over-the-counter market. To do this purpose the developnent and organization of an over-the-counter market must precede rapidly. 5. Reduction of taxation to bond interest; An appropriate tax reduction measure must taken for the absorption of the bonds and fromotion of negotiability.
