Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

<P>Recent studies suggest that faint active galactic nuclei may be responsible for the reionization of the universe. Confirmation of this scenario requires spectroscopic identification of faint quasars (M-1450 > -24 mag) at z greater than or similar to 6, but only a very small number of such quasars have been spectroscopically identified so far. Here, we report the discovery of a faint quasar IMS J220417.92+011144.8 at z similar to 6 in a 12.5 deg(2) region of the SA22 field of the Infrared Medium-deep Survey (IMS). The spectrum of the quasar shows a sharp break at similar to 8443 angstrom, with emission lines redshifted to z = 5.944 +/- 0.002 and rest-frame ultraviolet continuum magnitude M-1450 = -23.59 +/- 0.10 AB mag. The discovery of IMS J220417.92+011144.8 is consistent with the expected number of quasars at z similar to 6 estimated from quasar luminosity functions based on previous observations of spectroscopically identified low-luminosity quasars. This suggests that the number of M-1450 similar to 23 mag quasars at z similar to 6 may not be high enough to fully account for the reionization of the universe. In addition, our study demonstrates that faint quasars in the early universe can be identified effectively with a moderately wide and deep near-infrared survey such as the IMS.</P>

It is necessary to change SME and entrepreneurship policy responses to COVID-19. Despite the development of vaccines and remedies, COVID-19 is expected to be associated with humankind with influenza-like infectious diseases rather than termination, and ‘with Corona’ is understood as a new normal. The effects of COVID-19 is ① diffusion of an untact culture, ② promotion of digital transformation, ③ acceleration of the 4th industrial revolution, and ④ increased interest in health and the environment. The damage to SMEs caused by COVID-19 varies by industry. Corporate damage from COVID-19 has emerged in all industries, with the education services and other personal services industries suffering the most. COVID-19 is accelerating the 4th industrial revolution and accelerating changes in the industrial structure. The transformation of the industrial structure is progressing at different speeds and ranges for each industry. If existing companies are still leading smartization, there are still no major changes in the industrial structure. Platform companies and start-ups are pioneering the breakthroughs in industrial structures such as digital healthcare and legal tech, and the creation of new industries (fintech, autonomous vehicles, etc.). The governments SME policy direction will be strengthened from Smart-Up, Start-Up, and Stand-Up to Sum-Up, Scale-Up, and Value-Up based on the direction of industrial transformation. I would like to present the direction of change in the existing industrys Smart-Up, the new industrys Start-Up, and the digital governments Stand-Up strategy. This research consists of the content that proposes the conversion of SME support (Chapter 3-4) and the content that implements the digital government discussed on the global level (Chapter 5). Specifically, Chapter 2 analyzes the Moon Jae-in governments SME policies not only qualitatively but quantitatively. Chapter 3 presents the technological level of smart manufacturing in Korea through papers and patents, and presents the current status and the direction of improving the dissemination of smart factories. Chapter 4 raises the number of strategic investors and activation of M&A as main issues for the scale-up of startups, and diagnoses the current status and problems. Chapter 5 reviews the OECD Digital Government Index and examines cases in data-driven administration of major countries. In addition, we diagnose problems from the current state of digital government innovation in South Korea. Chapter 6 presents the direction of the new governments SME policy. There are three directions for the next governments SME policy to change. The first is to diversify the SME support method based on innovation. Second, promote open innovation, for example co-operatives. Third, accelerate the digital conversion of policy support. The next governments SME policy issues are as follows. We will reorganize the laws and regulations related to SMEs. Reorganize the growth-oriented certification and verification system and diversify corporate R&D support. Extend the ‘EXIT’ of the startup ecosystem. Promote cooperative R&D and transform into an ecosystem that fosters local businesses. Make manufacturing companies smarter and strengthen the capabilities of smart manufacturing professionals. Design a data-driven SME policy, collect data to support data-driven SMEs, and conduct an integrated survey.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

Jehovah's Witness comprise a unique obstetric population. Their refusal of blood stems from an interpretation of a literal translation of the Bible, and it is this belief that puts them at an increased risk of morbidity and mortality if hemorrhage occurs. We report two cases of a Jehovah's Witness who bled massively due to obstetric hemorrhage, refused blood transfusion and had profound anemia. The patients were treated with recombinant human erythropoietin, parenteral iron and oxygen. And they were treated on an intensive care unit with intermittent positive pressure ventilation. We reviewed with literature considering the therapy for acutely anemic patients who refuse transfusion to decrease the duration of the most severe anemia.

Unilateral pulmonary vein atresia is a rare congenital disease and is frequently associated with intracardiac anomalies. It is usually diagnosed in childhood and is very rarely diagnosed in adulthood. A case of unilateral pulmonary vein atresia in a 20-year old female is de- scribed. The relevant findings were symptoms of exertional dyspnea, roentgenographic evidence of decreased lung volume, increased interstitial infiltration with septal lines in the involved side (right), and aoscence of blood flow in a radionuclide perfusion scan. Pulmonary angiography showed an extremely small right pulmonary artery and thining of the peripheral branches, and nonvisualization of the draining pulmonary veins. Bronchial arteriography showed rommunication between the bronchial artery and the right pulmonary artery and it was drained to the left pulmonary artery. Cardiac catheterization showed no intracardiac anomaly. The right bronchography was normal; pulmonary function studies showed a pure restrictive pattern and markedly in creased physiologic dead space. MRI showed no visible right pulmonary vein.

A study was undertaken to evaluate the efficiency of the sytobrush compared with the cotton swab for obtaining cells from the uterine cervix. In 300 patients, the cytobrush technique was employed and in control 300 patients was smeared by the cotton swab. In 12 out of 300 patients(4%) endocervical cells were found on the cotton swab technique. A total of 252 out of 300 cytobrush sampler specimen(84%) contained endocervical cells. With the X²method for statistical comparison, the difference in endocervical cell yield between the cotton swab and the cytobrush sampler was significantly different(p<0.01). This was particularly true in older patients. We conclude from study that the cytobrush sampler is of value for obtaining as adequate cervical cytologic specimen.

In this paper, this study aims at the evaluation on the characteristics of CFRP laminate plates using a falling weight impact tester. The experiment was conducted on several laminates of different orientation. A system was built for measuring the impact strength of CFRP laminates in consideration of stress wave propagation theory using a falling weight impact tester. Delamination areas of impacted specimens for the different ply orientation were measured with ultrasonic C-scanner to find correlation between impact energy and delamination area. Absorbed energy of quasi-isotropic specimen having four interfaces was higher than that of orthotropic laminates with two interfaces. The more interfaces, the greater the energy absorbed. The absorbed energy of a hybrid specimen containing a GFRP layer was higher than that of normal specimens.
