The remote surveillance system based on the wireless home sensor network, wireless internet connection, and the portable, hand-held device has been designed for the patron to get the emergency alarm for immediate care for the Dementia aged, when the patron is not at home. It consists of transmitting server and the receiving terminal. The transmitting server gathers the information through bluetooth connection regarding to environment threatening the safety of the Dementia aged from five sensors, including fire, gas, conductivity, photo, and motion sensors, and cameras up to the number of 16, fixated within home. It also determines the emergency situation automatically from sensors' environmental condition and the motion detected from the camera output targeted to the aged people, and sends the alarm message with the picture taken from home to the patrol for comprehending the emergency situation remotely. Either the PDA or the cellular phone is used as the receiving terminal device through wireless connectivity without the location limitation for the patrol. The functional evaluation via the implemented prototype system has been performed to initially demonstrate the efficacy, the usefulness, and ease to operate for later use for either solitarily living old people or nursery schools and infantile shelters.

SUMMARY: Some of the information concerning sexual function in the male diabetes has been focused upon the problems of endocrine or semen parameters. However, the characteristics of acrosome reaction and spermatozoa concentration at the epididymis and vas deferens have scarcely been studied, and the causes of the infertility has not been critically identified. So, we designed to inspect the spermatozoa concentration and the characteristics of acrosome reaction at epididymis and was deferens of diabetic Wistar rat induced by streptozotocin (STZ, 70 mg/kg, ip). Experimental animal was sacrificed at 3 days and 14 days after the STZ injection. In the diabetes-induced rat, the levels of insulin and glucose had a pattern of inverse proportion. The spermatozoa concentrations in caput and corpus epididymis were significantly decreased in all diabetic condition. In cauda epididymis, however, there was significant decrease in sperm concentration at 14 days onward. In diabetic rat, the spontaneous reaction rate of spermatozoa of cauda and was deferens were significantly higher than the control group. The ARIC (acrosome reaction to ionophore challenge) value of caudal sperm was 28.7 at control, 22.1 at 3 days, and 8.3 at 14 days. In the present study the spermatozoa concentration was decreased and the spontaneous reaction rate was increased by diabetes. In ARIC-test, it is revealed that the fertility of spermatozoa of 14 days group was lower than control or 3 days group. Diabetes mellitus may be provoke the decreased fertilization rate and subsequent infertility.

The natural killer(NK) cell activity of mononuclear cells (MNC) from peripheral blood (PB) and synovial fluid (SF) of 40 rheumatoid arthritis(RA) patients was investigated by employing 51-chromium-(51Cr) release microcytotoxicity and single cell cytotoxicity assays against K562 target cells. It has been revealed that SF-MNC from RA patients showed a significantly lower NK activity than PB-MNC from the same patients and this might be due to an impaired target binding capacity of the effector cells and not due to a deficiency of active NK cells.

Human chorionic gonadotropin (HCG) is one of the glycoproteins families synthesized by the placenta, and consists of 2 noncovalently joined subunits, namely, alpha and beta. The alpha and beta-subunits have a structural homology with the alpha and beta-subunits of TSH and LH. The thyrotropic action of HCG results from its structural similarity to TSH, so beta-HCG can bind to the TSH receptor in the thyroid gland. A high level of HCG, accompanied by an increased thyroid hormone level, can be observed in gestational trophoblastic diseases (GTD), such as a hydatidiform mole or a choriocarcinoma. However, the clinical symptoms of hyperthyroidism in GTD are rarely observed. A 27-years-old woman, admitted due to an amenorrhea of 11 weeks duration, with thyrotoxic symptoms, such as weight loss, palpitation, sweating, tremor, heat intolerance and anxiety, was evaluated. Her serum free T4 level was 8 times higher than normal, and her serum beta-HCG level was over 1,000,000IU/L. She had a curettage operation, with the pathological findings of a complete hydatidiform mole. These thyrotoxic symptoms developed due to a hydatidiform mole, and were accompanied with a highly increased serum beta-HCG level. After evacuation of the molar tissue, the thyroid hormone and thyrotoxic symptoms normalized. Here, this case is reported, with brief review of the literature.

The Ael subgroup expresses the least amount of A antigens and could only be detected by performing the adsorption-elution test. The frequency of the Ael subgroup is about 0.001% in Koreans, and the Ael02 allele, which originates from A102, is the most frequently identified allele in the Korean population. We report a Korean family with the Ael03 allele identified by molecular genetic analysis. To the best of our knowledge, this is the first such report in Korea to date.

PURPOSE: We analyzed pelvic ultrasonography (USG) findings in girls with central precocious puberty (CPP) and assessed the role of uterine and ovarian measurements in discriminating between CPP and other pubertal conditions. METHODS: Seventy-four girls (chronological age 7.8 +/- 0.5 years, bone age 9.9 +/- 0.8 years) with precocious pubertal signs were enrolled. Measurements of uterine and ovarian parameters by pelvic USG included antero-posterior diameters of the uterine fundus and cervix, diameter of each ovary, number of follicles, and maximal diameter of the largest follicle. The pelvic USG parameters were compared between girls with CPP (n = 49) and girls with atypical premature thelarche (PT) (n = 25). RESULTS: Antero-posterior diameter of uterine fundus (1.05 +/- 0.34 vs. 0.74 +/- 0.78 cm, P = 0.001), maximal ovarian diameter (2.13 +/- 0.48 vs. 1.84 +/- 0.74 cm, P = 0.048) and mean ovarian area (2.31 +/- 0.79 vs. 1.69 +/- 0.71 cm, P = 0.002) were significantly greater in girls with CPP than in girls with atypical PT. For the diagnosis of CPP, the sensitivity and specificity of A-P diameter of uterine fundus (> 0.9 cm) was 65.3% and 84.0%, the sensitivity and specificity of maximal ovarian diameter (> 2.0 cm) was 55.1% and 76%, and the sensitivity and specificity of mean ovarian area (> 2.0 cm2) was 62.9% and 80.0%. CONCLUSION: Girls with CPP had significantly higher dimensions of the uterus and ovary measurements compared to girls with atypical PT, but sensitivity and specificity were not high enough to differentiate CPP from atypical PT. Pelvic USG may help the diagnosis of CPP in girls.

BACKGROUND: In the severe community-acquired pneumonia, it has been known that the immune status is occasionally suppressed. This study was performed to identify the immunologic markers related with the prognostic factors in severe community-acquired pneumonia. METHODS: 23 patients with severe community-acquired pneumonia were involved in this study, and divided into survivor (16) and nonsurvivor (7) groups. In this study, the medical history, laboratory tests(complete blood counts, routine chemistry profile, immunoglobulins, complements, lymphocyte subsets, cytokines, sputum and blood culture, urine analysis), and chest radiographs were scrutinized. RESULTS: 1) Both groups had lymphopenia(total lymphocyte count 995.6±505.7/mm2 in the survivor and 624.0±287.6/mm2 in the nonsurvivor group). 2) The T-lymphocyte count of the nonsurvivor group(295.9±203.0/mm2) was lower than the survivor group(723.6±406.5/mm2) (p<0.05). 3) The total serum protein(albumin) was 6.0±1.0(2.7±0.7) g/dl in the survivor and 5.2±1.5(2.3±0.8)g/dl in the nonsurvivor group. The BUN of the noncurvivor group(41.7±30.0mg/dl) was higher than that of the survivor group(18.9±9.8mg/dl)(p<0.05). The creatinine concentration was higher in the nonsurvivor group(1.8±1.0mg/dl) than that in the survivor group(1.0±0.3mg/dl)(p<0.05). 4) The immunoglobulin G level was higher in the survivor group (1433.0±729.5mg/dl) than in the nonsurvivor group(849.1±373.1mg/dl)(p<0.05). 5) The complement C3 level was 108.0±37.9mg/dl in the survivor group and 88.0±32.1mg/dl in the nonsurvivor group. 6) A cytokine study showed an insignificant differenne in both groups. 7) Chronic liver disease, DM, and COPD were major underlying diseases in both groups. CONCLUSION: These results suggest that decreased a T-lymphocyte count and immunoglobulin G level, and an increased BUN and creatinine level may be associated with the poor prognosis of severe community-acquired pneumonia.

BACKGROUND:In this study, a distribute characteristics on the bispectral coupling of EEG were examined according to the depth of anesthesia by using bispectum analysis a type of nonlinear signal processing. METHODS: 25 patients during the general anesthesia were studied. In the preprocess, base line correction and linear detrend was used. During the awakening state, preoperatively and postoperatively, appearance rate of bispectral coupling was observed that a strong appearance rate was represented in major frequency zone such as (15, 15) Hz but weak appearance rate investigated in the other minor frequency zone. Whilst anesthetized, a strong appearance rate revealed the low frequency range below (10, 10) Hz and a weak appearance rate viewed in the other frequency range. As such was compared with the delta ratio and spectrum edge frequency (SEF). RESULTS: The delta ratio showed significantly lower values at induction (3.60 +/- 0.98) and during the maintenance (5.0+/-1.74) of anaesthesia than preoperatively (10.30 +/- 2.44) and postoperatively (13.03 +/- 2.29)(P < 0.05). These results were consistent with the trend of delta ratio, namely that the index of evaluation for the depth of anesthesia, known as the reflex of the conscious level of patient's during anesthesia. While these results were not consistent with SEF analysis results that the index of evaluation for suppression level of patient's during recovery stage of anesthesia. SEF shows lower values at maintenance (17.00 +/- 1.22) and postoperatively (12.20 +/- 1.53) than preoperatively (22.50 +/- 1.75) and at the induction (22.40 +/- 1.18) of anesthesia(P < 0.05). CONCLUSIONS: The bispectrum analysis method provided useful information about the index of evaluation according to the level of unconsciousness and suppression among other evaluation factor on depth of anesthesia.

BACKGROUND: Donor screening test is one of the most important processes for blood safety management. Korea Center for Disease Control and Prevention (KCDC) has been conducting an annual proficiency test program that includes the distribution of specially manufactured panels for hepatitis B surface antigen (HBsAg) and antibody to hepatitis C virus (anti-HCV) to blood centers. Here, KCDC reports the results of these proficiency tests for HBsAg and anti-HCV blood donor screening for all licensed blood centers in Korea between 2012 and 2015. METHODS: Panels for the proficiency tests were manufactured and distributed to blood centers by Chung-Ang University Hospital, which has been participating in the Korea Blood Safety Commission. Well-proven reactive sera and healthy donor's sera acquired from the Human Serum Bank in Chung-Ang University were used to make the panels. To identify the S/CO ratio of the panel, three medical institutes triple-checked the results of each panel. RESULTS: Most blood centers reported correct answers for the proficiency test with six panels. The average percentages (year) of correct answers were as follows: 98.7% (2012), 98.5% (2013), 99.1% (2014) and 99.6% (2015) for the HBsAg proficiency tests; and 97.7% (2012), 99.5% (2013), 99.1% (2014), and 99.8% (2015) for the anti-HCV proficiency tests. CONCLUSION: To improve the blood center's ability for donor screening tests, KCDC will continue the proficiency test program by managing specialized panels for HBsAg and Anti-HCV tests. Furthermore, we will investigate the level of satisfaction to improve the quality of the program.
