We intended to determine the usefulness of window operation for adult hydrocele repair. We reviewed medical records of 132 patients from January 1995 to June 1998 with primary hydrocele and evaluated complications and recurrence rates of eversion and/or excision, plication, and internal drainage technique. Recurrence rate was highest in internal drainage technique as 85.2%, and those of eversion and/or excision and plication technique were 1.3% and 4%, respectively. Complication rate was highest in eversion and/or excision technique, and lowest in internal drainage technique. Although complication rate was lowest in window operation, this operation could not be successful due to high recurrence, and we suggest that this operation should be abandoned for hydrocele repair.

Although ureteroscopy(URS) has been used widely to remove ureteral calculi, there is an argument against the belief that anesthesia or admission is needed for URS. We evaluated the experience of URS without anesthesia in female patients. From September 1997 to July 1998, URS was performed in 31 female patients without anesthesia. EHL(Electrohydraulic Lithotripsy) was used in 21 patients with impacted or large stone over 5mm. All patients were given oral antibiotics for 3 days and follow-up KUB was taken to confirm successful removal of the stone one week after the procedure. Successful treatment was defined as complete removal of the stone or residual fragments less than 2mm. Overall success rate was 96.7%(30 cases among 31 cases). All but one patient tolerated with analgesia through the entire procedures. There were only minimal complications such as mild flank pain and hematuria. So, we recommend that non-anesthetic ureteroscopic removal of stone as the first choice for treatment of lower ureteral stones in female based on the minimal morbidity, high success rate and low cost.

산업용로봇과 CNC 가감속을 위한 FPGA 설계

하영열,전재욱 成均館大學校 科學技術硏究所 1997 論文集 Vol.48 No.1

Many techniques for velocity profiles of industrial robots and CNC machine tools have been proposed in order to make industrial robots and CNC machine tools perform given tasks efficiently. Since they should be calculated in a limited time, most of them are not computationally intensive. In particular, some of the previous techniques calculate velocity profiles with hardware techniques for the reduction of calculation time of velocity profiles. However, these techniques cannot generate velocity profiles having some kinds of velocity profiles. This paper proposes a FPGA design to be able to generate velocity profiles which cannot be generated by previous hardware techniques as well as velocity profiles generated by them. Simulation results of VHDL programs for FPGA will be explained how to generate typical velocity profiles for the given condition.

우영대,--,--,--,--,-- 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.1

The etiologic agents of haemorragic fever with ranal syndrom (HFRS) in Korea are Hantaan and Seoul virus in the genus Hantavirus, family Bunyaviridae. In order to elucidate the role of maternal immunity to Hantavirus infection in rats, the protective effect of the maternal antibody were studies by using rats experimentally infected with Seoul virus strain HR80-39. Antibody titers of sera and viral antigen against Seoul virus were investigated by indirect immunofluorscence antibody technique (IFA). The dam sera had IFA antibody titers ranging from 1:128 to 1:1,024 after parturition. In fetuses, IFA antibody titers ranged from 1:16 to 1:64 just after birth, increased to peak titers ranged from 1:256 to 1:1,024 in the 2nd week after birth. Challenged newborn rats had IFA antibody titers ranging from 1:64 to 1:1,024 after inoculation. No viral antigen was detected in lungs or other organs of the newborn rats. The maternal antibody to Seoul virus was transferred prenatally through placenta and postnatally via colostrum from immune dams to their offspring. These results demonstrated that maternal antibody to Seoul virus was quite effective in protecting newborn rats against same virus infection.

관상동맥질환에서 Tc-99m Methoxyisobutyl Isonitrile (MIBI) Myocardial SPECT의 이용 : Dipyridamole 심근부하 SPECT와 관상동맥조영술과의 비교 A Comparison between Coronary Angiography and Tc-99m-MIBI Myocardial SPECT

In order to evaluate clinical utilities of Tc-99m MIBI dipyridamole stress myocardial SPECT in patients with coronary artery disease (CAD), we compaired tomographic and polar map images of Tc-99m MIBI myocardial SPECT with the results of coronary angiography in 25 patients with CAD (myocardial infarction 13,angina pectoris 12) in Chungnam National University Hospital from Oct. 1991 to Oct 1993. Percutaneous transcoronary angioplasty (PTCA) was done in three patients of 25 CAD patients and follow up SPECT studies were done in same three patients within 2 months after PTCA. The results were as follows : 1. Mean age of patients was 57.4 years. Man was 2.7 times more than woman. 2. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with myocardial infarction were 92.7 % anf 85 %, respectively. 3. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with angina pectoris were 100 % and 67 %, respectively. 4. After PTCA size of perfusion defects in stress SPELT images was decreased in all three patients . With the results above,we thought that Tc-99m MIBI myocardial SPECT is useful noninvasive method to detect stenosed coronary artery in patients with CAD and it can be used as a method to evaluate the result of PTCA.

Objectives : In this study, the authors evaluated the correlation between eurocognitive impairments and serum lipids levels among Korean elderly over the age of 65. Methods : A total of 609 elderly individuals participated in this study. Screening for cognitive impairments were carried out using the Mini-Mental Status Examination-Korean version (MMSE-KC). There were 197 subjects above 1.5SD Of MMSE- KC and they were evaluated using the Korean versions of the Consortium to Establish a Registry for Alzheimer's Disease (AD) (CERAD-KC) and Geriatric Depression Scale (GDS-K). Results : There was a correlation between old age/low levels of education and AD (p<0.05, P<0.01). There was an inverse correlation between the serum level of total cholesterol and the word list recognition test scores. The serum levels of LDL cholesterol were inversely correlated with the scores on the constructional praxis test, word list recall test and word list recognition test. Inverse correlations between the serum level of triglyceride and scores on the word list recall test and word list recognition test were also observed. Conclusion : There were inverse correlations between the serum levels of lipids and language/memory function in subjects with AD.

The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

In this paper, a high-speed, high-precision chip mount system by using DOS rather than a real-time OS is designed and implemented. A monitoring feedback loop to reduce positional errors in this chip mount system is applied, which can reduce some errors due to disturbances as well as truncation errors. Existing chip mount systems will be compared with the designed and implemented chip mount system.

Semantic dementia (SD) is a very rare, distinct form of dementia which is characterized by impairment of naming and comprehension, prosopagnosia, visual agnosia for objects and relative preservation of other aspects of cognition, such as episodic memory, nonverbal problem-solving and visuospatial functions. A 68-year-old man visited our clinic for progressive speech disturbance since 1997. His main speech problems were word finding difficulty and loss of word meaning for objects. Language assessment demonstrated profound semantic memory loss for words with preserved fluency, corresponding to anomic aphasia. There were marked impairments in verbal and visual memory functions and word fluency tasks, but no grammatical or phonologic errors in speech. Also were remarkable anosognosia and object visual agnosia with preserved visuospatial function and calculation in neuropsychological tests. Serial follow-up study of language test showed more deterioration in comprehension and repetition, consistent with Wernicke's aphasia. Initial brain MR imaging and brain perfusion SPECT showed prominent focal atrophy in the left temporal lobe, and marked hypoperfusion in the left temporal and both frontal areas. Follow-up brain MR imaging and perfusion SPECT revealed more atrophy in both temporal lobes and showed more extensive hypoperfusion areas compared to the previous study.
