OBJECTIVE: To evaluate the current status and new trends in gynelcological pelviscopy in Korea. METHODS: A survey was conducted and analyzed based on 20997 cases of operative pelviscopy hom May, 1985 to February, 1998 reported from twenty four university hospitals in Korea. RESULTS: The results obtained were ss followings; 1) 45.9 % of the total cases was 30 to 39 years old age group and it was the most dominant age group, 2) The previous operative history was found in 10.9% of the tota1 cases and included cesarean section(30.0%), ectopic pregnancy(20.3%), etc. 3) The operative indications were diagnostic(26.2%), myoma uteri(23.1%), ectopic pregnancy(21.4%), adnexal mass(18.4%), etc. In cases of diagnostic indication, the most common post-operative diagnosis of pelviscopic surgery was tubal pregnancy(30,6%). 4) The operative titles were salpingectomy(25.1%), hysterectomy(19.9%), salpinghorectomy(19.8%), etc. 5) The complications of operative pelviscopy were composed of subcutaneous emphysema(0.58%), preperitoneal bleeding(0.3%), bladder injury(0,3%), bowel injury(0.3%), etc. 6) lhe survey showed that 57.1% of the respondents desired more than 1 year of period for well peration between the operator and the assistant. 56.7% of respondents indicated that the surgical technique of the operator was the most important factor for a successful pelvisocopic surgery. 7) The most beneficial effect of the pelviscopy included the comfortableness of the patient(40.0%), cosmetic effect(22.8%), decrease of complications(14.2%), etc. CONCLUSION: The modem methods of operative pelviscopy have been successfully used in the treatment of gynecological disease. Today, pelviscopic surgery is being applied in almost all the cases of gynecological disease. Hence, the majority of pelviscopy techniques and pracedures being performed by surgeon must be taught in the controlled setting of a residency or a fellowship training program.

Purpose: This study aimed to understand the keywords and major topics of the educational goals and objectives of nursing educational institutions in South Korea. Methods: From May 10 to May 20, 2022, the educational goals and objectives of all 201 nursing educational institutions in South Korea were collected. Using the NetMiner program, degree and degree centrality, semantic structure, and topic modeling were analyzed. Results: The top keywords and semantic structures of educational goals included ‘respect for human (life)-spirit-science-based on, global-competency-professional nurse-nursing personnel-training, professional-science-knowledge-skills, and patients-therapeutic care-relationship.’ The educational goals’ major topics were clients well-being based on science and respect for human life, a practicing nurse with capabilities and spirit, fostering a nursing personnel with creativity and professionalism, and training of global nurses. The top keywords and semantic structures of the educational objectives included ‘holistic care-nursing-research-action-capability, critical thinking-health-problem solving-capability, and efficiency-communication-collaboration-capability.’ The educational objectives’ major topics were ‘nursing professionalism, communication and problem-solving capability; a change of healthcare environments and a progress of nursing practices; fostering professional nurses with creativity and global capability; and clients’ health and nursing practice.’ Conclusion Educational goals in nursing presented specific nursing values and concepts, such as respect for human life, therapeutic care relationships, and the promotion of well-being. Educational objectives in nursing presented the competencies of nurses as defined by the Korean Accreditation Board of Nursing Education (KABONE). Recently, the KABONE announced new program outcomes and competencies, which will require the revision of educational goals. To achieve those educational objectives, it is suggested that the expected level of competencies be clearly defined for nursing graduates.

Herlyn-Werner-Wunderlich syndrome(HWWs) is a rare variant of Mullerian ductal anomalies characterized by the presence of a hemivaginal septum, a didelphic uterus, and ipsilateral renal agenesis. It usually presents after menarche with progressive pelvic pain, and palpable mass due to hemihematocolpos. If a cystic mass is detected behind the urinary bladder in children, in association with the absence of a kidney, the diagnosis of uterus didelphys with imperforate vagina and hydrocolpos should be considered. When renal agenesis is found in asymptomatic children, the small size and the tubular shape of the uterus makes it almost impossible to evaluate uterine anomalies, so follow-up should be performed until the end of puberty. Appropriate preoperative diagnosis and treatment will prevent unnecessary procedures and offer relief of symptoms. We report one case of didelphic uterus with blind hemivagina and ipsilateral renal agenesis with biopsy-proven thin glomerular basement membrane disease which is not related to the above syndrome.

Objective: Although the Clinical Dementia Rating (CDR) scale was originally developed to stage Alzheimer’s dementia (AD), it is now used globally for various types of dementia. The aim of this study was to investigate the characteristic pattern of CDR domains and its association with neuropsychological findings and activities of daily living (ADL) in patients with vascular dementia (VaD) and patients with AD. Methods: We recruited very mild to mild VaD and AD patients who were age-matched among the first visitors to a dementia clinic. All subjects underwent a standardized clinical interview, physical and neurological examinations, and laboratory tests, including brain magnetic resonance imaging, according to the protocol of the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment battery. Results: A total of 105 pairs of VaD and AD patients participated in this study. Although the adjusted scores on Korean version of the Mini-Mental State Examination were similar between the two groups, the VaD patients performed better on the Boston Naming Test, Word List Memory, Word List Recall, Word List Recognition, and Constructional Recall Test. However, the scores on global CDR, CDR sum of boxes, and ADL-related CDR domains were higher in VaD patients than in AD patients (p<0.001). The VaD patients also showed poor performances on the Disability Assessment for Dementia Scale, Frontal Assessment Battery, Executive Clock Drawing Task, and Stroop tests. Conclusion Despite similar general cognitive function and better memory function, patients with VaD tend to be staged as severer dementia on the CDR scale than patients with AD because of more impaired ADL associated with executive dysfunction.

PURPOSE: It has been reported that neovascularization of the optic disc (NVD) occurs in ocular ischemic syndrome, sickle cell hemoglobinopathy, ocular sarcoidosis, Eales' disease, and central retinal artery occlusion. However, NVD in acute ophthalmic artery occlusion had not been reported. Therefore, we report one unusual case of NVD in acute ophthalmic artery obstruction. METHODS: A 56 year-old man with complaint of abrupt decrease of visual acuity and periorbital discomfort underwent medical history taking, periorbital examination, fundus examination, and fluorescein angiography. He was followed up for 5 months RESULTS: Fundus examination showed segmentation of blood flow and diffuse retinal whitish opacity on the posterior pole around the center of the macula, without any cherry red spots in the perifoveal area. Fluorescein angiography showed a marked filling delay in the nasal retinal and choroidal circulations with a definite watershed zone involving the peripapillary choroid and macula. The retinal arteries filling and arteriovenous transit time were delayed. There was no light-perception vision and low intraocular pressure. Diabetes was found on systemic examination. Five weeks later, NVD and choroidal atrophy around the optic disc were detected. Panretinal photocoagulation was performed for the regression of NVD. NVD was regressed, but recurred.

In this study, we are to produce the single chain variable fragment (scFv) antibodies against surface protein of hepatitis B virus (HBV) using antibody phage display technique. Balb/c mice were immunized with preS1 and cDNAs of heavy and light chains of splenic B cells from immunized mice were prepared using RT-PCR. Two cDNAs were linked with (64S) linker DNA under recombination PCR to produce single chain Fv DNA. After digestion of scFv DNA with Sp 1 and Not 1, the digested DNA was ligated into pCANTAB 5E and electroporated into E. coli XL1-Blue to prepare scFv-library. The size of library was 1 * 10' pfu/ml. Phage antibodies (phabs) against preS1 were rescued with M13K07 helper phages, and preS1-binders were selected through 3 times of panning using 96 well microtitre plates. Phage antibody clones were assayed directly for the ability to bind preS1 by ELISA. And then 7 phage antibody clones had high ELISA signals against preS1. Phabs from preS1-specific pMsc-17 had the strongest ELISA signal to preS1. Phabs from pMsc-17 were used for Western blot to preS1 and the results revealed that it was specific to preS1. To prepare the soluble scFv antibody, phabs from pMsc-17 were transfected into non-suppressor E. coli HB2151, and grown under 1 mM IPTG. Soluble scFv antibody was mainly accumulated in the periplasmic space, but small amount of antibody was secreted into culture media.

Human monoclonal antibodies have considerable potential in the prophylaxis and treatment of viral disease. By cloning human Ig gene segments from the B cells of volunteer into pComb3 phagemid vector, antibody library was created of filamentous phage particles displaying Fab fragments on their surface after being rescued with M13KO7 helper phages. The size of library was 7x10' pfu. Phage antibodies (phabs) were panned against biotinylated preS1 using streptavidine coated Dynabead. The soluble Fab antibodies were prepared from phagemid colonies and assayed directly for the ability to bind preS1 by ELISA. And then 3DW and SGW specific to preS1 which have both heavy and light chain to form Fab fragment, were selected. The soluble Fab antibody from 3DW was expressed highly at the concentration of 0.1 - 1.0 mM of IPTG, and 5 hours postinduction. The soluble antibodies from 3DW and SGW showed their relative affinities of 2x10' M ', and Sx10 M ', respectively, and the specificities to preS1 on ELISA. Our results suggest that antibody phage display library is very useful method to generate the human monoclonal antibody and that the human Fab monoclonal antibodies specific to preS1 selected in this study open the way to treat hepatitis B as a component of passive irnmunotherapeutics.
