In 1968, Cairns introduced the trabeculectomy operation and reported it to be a highly succesful form of surgery for the reduction of intraocular pressure in primary open-angle glaucoma. At the present time trabeculectomy is the treatment of choice for patients with primary open-angle glaucoma requiring surgery. In the period January, 1975. to March, 1978, 72 eyes of chronic simple, chronic angle-closure, secondary, and developmental glaucoma were operated by trabeculectomy and/or trabeculotomy in Busan National University Hospital. Follow-up study was achieved in 28 eyes(chronic simple glaucoms 17, chronic angle-closure glaucoma 4, secondary glaucoma 3, and developmental 4) of 72 eyes, and the duration of follow-up ranged from 1 year to 2 and 1/2 years(average 18 months). Our operative procedure, which was different from others, was made with 1/3 thickness of scleral flap, and made 2 knots with 8-0 nylon placed in free edge of scleral flap and 1/3 of all cases was not placed scleral flap sutures. We achieved success in 23 eyes (82.1% )of 28 eyes of all types of glaucoma and 14 eyes (82.4%) of 17 eyes of openangle glaucoma. The control of intraocular pressure in interrelationship to formation of filtering bleb was statistically significance(x2(0.05, 1)=3.84>5.46), and to scleral flap suture was not significance(x2(0,05, 1)=3.84>0.39). The complications during and after operation were delayed formation of anterior chamber, hyphema, posterior synechia, vitreous prolapse, choroidal detachment, and lens and vitreous opacity in order.

The gene encoding F protein of CBP-1 strain, a heat-stable Newcastle disease virus (NDV) isolated from the diseased pheasants in Korea, was characterized by reverse transcription-polymerase chain reaction (RT-PCR), nucleotide and amino acid sequences. Virus RNA was prepared from the chorioallatoic fluid infected with NDV CBP-1 virus and cDNA was amplified by RT-PCR, cloned and sequenced to analyze. The PCR was sensitive as to detect the virus titer above 25 hemagglutination unit. 1.7kb (1,707bp) size of the cDNA was amplified and cloned into BamHI site of pVL1393 Baculo transfer vector. The nucleotide sequences for F protein were determined by dye terminator cyclic sequencing using four pairs of primers, and 553 amino acid sequences were predicted. In comparison of the nucleotide sequence of F gene of CBP-1 with those of other NDV strains, the homology revealed 88.8%, 98.5% and 98.7% with Kyojungwon (KJW), Texas GB and Beaudette C strains, respectively. As the deduced 553 amino acid sequences of F protein of CBP-1 were compared with those of other NDV strains, the homology appeared 89.9%, 98.7% and 98.9% with KJW, Texas GB and Beaudette C strains, respectively. The putative protease cleavage site (112-116) was R-R-Q-K-R, indicating that CBP-1 strain is velogenic type. The amino acid sequences include 6 sites of N-asparagine-linked glycosylation and 13 cysteine residues. These data indicate that the genotype of CBP-1 strain is more closely associated with the strains of Texas GB and Beaudette C than KJW strain.

The purpose of this article is to present the clinical and laboratory procedures for single tooth restoration using "Combination Implant Crown". It is cemented on implant abutment and that abutment is screw-retained over implant body. This type of implant restorations has the advantages of cement-retained restoration while being antirotational and retrievable. And, more esthetic and functional result can be achieved by minimizing the size of access hole. The results were as follow : 1. Preparation of abutment below the cuffline should be avoided 2. Axial reduction of implant abutment should not be excessive because it may weaken the abutment 3. More esthetical and functional occlusal surface was achieved with a minimal access hole which is slightly larger than the diameter of hex driver to enable future total retrievability. 4. Combination Implant Crown has the advantages of both the cement-retained and screw-retained type implant restoration. 5. Cementation between implant crown and abutment reduces screw loosening through even force distribution.

PURPOSE: To compare the clinical features according to the presence of anisometropia in refractive accommodative esotropia patients. METHODS: Forty-five refractive accommodative esotropia patients were divided into 2 groups : patients who had anisometropia of more than 1.00D (anisometropia group), and patients who had anisometropia of less than 1.00D (isometropia group). Age at onset, age when glasses were first worn, the initial and final angle of esotropia with or without hyperopic correction, the recovery time to orthophoria after hyperopic correction, the degree of stereoacuity and the frequency of amblyopia, the prevalence of deterioration, and the ratio of accommodative-convergence to accommodation were retrospectively reviewed. RESULTS: There were no statistical differences between the 2 groups in the frequency of amblyopia, the prevalence of deterioration, and the ratio of accommodative-convergence to accommodation at the initial and final visit. The angles of deviation with hyperopic correction at the 1-month follow-up visit in the anisometropia group and the isometropia group were 8.80 +/- 5.63 PD for near, 8.67 +/- 5.42 PD for distance, and 4.54 +/- 6.59 PD for near 5.19 +/- 6.7 PD for distance, respectively; the difference was statistically significant (p = 0.042). The recovery time to orthophoria after hyperopic correction in patients associated with anisometropia was 2.20 +/- 1.01 months, significantly longer than 1.47 +/- 0.86 months in patients associated with isometropia (p = 0.017). CONCLUSIONS: In refractive accommodative esotropia patients associated with anisometropia, the recovery time to orthophoria after hyperopic correction was significantly prolonged but there were no statistical differences in other clinical manifestations.

The purposes of this study are to define the scope of occupational health management and to classify occupational management by review of related journals from 1945 to 1994 in Korea. The steps of this study were as follows: (l)Search of secondary reference; (2) Collection and review of primary reference; (3) Survey; and (4) Analysis and discussion. The results were as follows; 1. Most of the respondents majored in occupational health(71.6%), and were working in university (68.3%), males and over the age 40. Seventy percent of the respondents agreed with the idea that classification of occupational health management is necessary, and 10% disagreed. 2. After integration of the idea of respondents, we reclassified the scope of occupational health management. It was defined 3parts, that is, occupational health system, occupational health service and others (such as assessment, epidemiology, cost-effectiveness analysis and so on). 3. The number of journals on occupational health management was 510. It was slightly increased from 1986 and abruptly increased after 1991. The kinds of journals related to occupational health management were The Korean Journal of occupational Medicine(18.2%), several kinds of Medical College Journal(17.0%), The Korean Journal occupational Health(15.l%), The Korean Journal of preventive Medicine(15.l%) and others(34.6%). As for the contents, the number of journals on occupational health management systems was 33(6.5%) and occupational health services 477(93.5%). Of the journals on occupational health management systems, the number of journals on the occupational health resource system was 15(45.5%), occupational finance system 8(24.2%), occupational health management system 6(l8.2%), occupational organization 3(9.1%) and occupational health delivery system l(3.0%). of the journals on occupational health services, the number of journals on disease management was 269(57.2%), health management 116(24.7%), working environmental management 85(18.1%). As for the subjects, the number of journals on general workers was l85(71.l%), followed by women worker, white color workers and so on. 4. Respondents made occupational health service(such as health management, working environmental management and health education) the first priority of occupational health management. Tied for the second are quality analysis(such as education, training and job contents of occupational health manager) and occupational health systems(such as the recommendation of systems of occupational and general disease and occupational health organization). 5. Thirty seven respondents suggested 48 ideas about the future research of occupational health management. The results were as follows: (l) study of occupational health service 40.5%; (2) Study of organization system 27.1%; (3) Study of occupational health system (e.g. information network) 8.3%; (4) Study of working condition 6.2%; and (5) Study of occupational health service analysis 4.2%.

Submerged implants require secondary surgical uncovering of implants after healing period of 3 - 6 months. In surgical methods, there are surgical scalpel, tissue punch, electro-surgical, and laser-used uncovering, and laser-used uncovering, and so forth. The objectives of this study are investigation and assessment of 1) thermal change in clinical application for uncovering of HA-coated implant and pure titanium implant irradiated by pulsed Nd-YAG. CO2, and Er-YAG laser. 2) surface change of cover screws after irradiation using laser energy. The temperature of apex & side wall of implants were recorded at 10sec, 20sec, 30sec after 30sec irradiation to implant healing screw; 1) pulsed Nd-YAG laser; 2W, 20pps, contact mode 2) CO2 laser; water-infused & non-water infused state, 2.5-3.5W, contibuous mode, noncontact mode 3) CO2 laser; non-water-infused state, 3W, superpulse, noncontact mode 4) Er-YAG laser; (1) non-water infused state, 10pps, 60mj, contact mode (2) water-infused state, 10pps, 60mj, 80mj, 101mj, contact mode According to the results of this study, pulsed Nd-YAG laser is not indicated because of increase thermal change and pitting of metal surface of implant cover screw. By contrast, CO2 laser & Er-YAG laser are presumed to indicate because of narrow range of thermal change & near abscence of thermal damage of metal surface. Dental laser is thought to be much helpful to surgical procedure when it is used as optimal power and time condition considering characteristics and indications of each laser. Further research is needed to verify that these techniques are safe and beneficial to implant success.
