In arctic zone of West Siberia, native people's bodies were sometimes mummified inside the medieval graves. In 2013 to 2017, we conducted the excavations of medieval graves at Zeleny Yar cemetery in Yamalo-Nenets Autonomous Okrug. Among the burials, current report deals with the mummy grave #79. During the investigation, bronze plate and strips, woven or fur clothing, leather strap, beads, bronze bracelets, and iron knife etc. were collected. Anatomical and radiological research showed that the mummy was found intact with hair, skin, and skeletons, but the preservation status of soft tissue differed greatly depending on the area. The brain and eyes were well preserved, but the chest and abdominal organs almost disappeared. The arms were preserved to some extent, but only the bones remained in the legs. The West Siberian mummy could be a great resource for anthropologists to reveal the biological aspects of arctic indigenous people.

This study is designed to evaluation of the Community based Opthalmologic Health Services(CBOHS) for elderly carried out for last three years from 1994. The subjects were total 236 aged over 57 in Chuncheon city. Kangwon province. and the period of data collection was from Feb. 24th. 1996 to Feb. 27th. 1996. For evaluation of CBOHS. the questionnaire was consisted of participation rate. and perception about the service. the level of satisfaction and things to improve. Result were obtained as follows: 1. The number of participants was $95(40.3\%)$ among total subjects. The places provided services were the health service center of Seoul National University in Chuncheon city and community health center. The participants were known from announcements of community staff$(66.3\%)$. 2. Non participants were $59.7\%$ among total subjects. mam causes of missing wasn't known'. 3. The services that participants screening test$(41.2\%)$. provided provided operation$(45.5\%)$. 4. The question about things to improve were continuous follow up and more many glasses provision These fingings may indicate that the CBOHS need more announcement. continuous follow up and provide more many glasses. As proved the satisfaction of CBOHS for elderly. the next study can be performed about the relevant factor of the services.

We report the development of solar flux receivers operating at 2.8 GHz to monitor solar radio activity. Radio waves from the sun are amplified, filtered, and then transmitted to a power meter sensor without frequency down-conversion. To measure solar flux, a calibration scheme is designed with a noise source, an ambient load, and a hot load at $100^{\circ}C$. The receiver is attached to a 1.8 m parabolic antenna in Icheon, owned by National Radio Research Agency, and observation is being conducted during day time on a daily basis. We compare the solar fluxes measured for last seven months with solar fluxes obtained by DRAO in Penticton, Canada, and by the Hiraiso solar observatory in Japan, and finally establish equations to convert observed flux to the so-called Penticton flux with an accuracy better than 3.2 sfu.

Spinal cord stimulation (SCS) is used to manage chronic pain syndromes and it is accepted a cost-effective therapy. Child-bearing women who had SCS become or choose to become pregnant despite these policies pregnancy is a relative contraindication. A 32-year-old woman had SCS as a treatment for the CRPS I of the left lower extremity, During various check up tests, we happen to find out that her serum beta-hCG was positive and confirmed pregnancy. SCS is not recommended in pregnancy because the effects of SCS on pregnancy and nursing mothers had not been confirmed. However, many female patients suffering from chronic pain may expect future pregnancy and we think that they must be informed about the possibility of pregnancy and the effects of SCS device implantation in the course of pregnancy. First of all, a good outcome requires a multidisciplinary team approach, including obstetrics, neonatology, pain medicine and anesthesia, as was used from an early pregnancy. Unfortunately, she had a misabortrion after 6 weeks.

This paper presents the FIR filtering scheme for digital distance protection. In most faults, there exists severe oscillation of apparent impedance according to distortion in transient waveforms. In these cases, this scheme provides more accurate fault detection and fault location, as compared with conventional schemes for digital distance protection or Kalman filtering schemes. The test of these facts were performed on EMTP result data. For the real time implementation of the proposed schemes, the motorola DSP 56001 was used to the main calculation board of the digital protective relaying system.

The purpose of this study was to identify the relationship between bullying, nursing work environment, reality shock and factors of influence on turnover intension. Data were collected from 381 nurses who were under the charge nurse at a hospital with more than 600 beds in Seoul. The collected data were analyzed using the SPSS24.0 program. The mean score for turnover intension was 3.61 ± 0.89. The intension of turnover was correlated with bullying in the workplace (r=0.197, ⍴=.001), the nursing work environment (r=-.409, p=.001), and reality shock (r=.572, p=.001). Variables affecting turnover intension were the work department(β=-0.018, ⍴=.049), working environment(β=-0.424, ⍴<.000), and reality shock(β=0.654, ⍴<.000). The total amount of explanation for turnover intension was 37.3%. The degree of turnover intension of nurses was affected by work in general wards, the experience of workplace bullying and the nursing work environment. To reduce turnover intension, nursing work needs to be analyzed and efforts are needed to establish an effective communication system.

Higenamine is known as a cardiotonic principle of Aconiti tuber. The analytical procedures were established for the detection of higenamine in plants. The amounts of higenamine in several Aconiti tubers and the embryo of Nelumbo nucifera, another plant species known to contain higenamine, were determined. The $H_2O$ soluble fraction prepared from MeOH extract was first treated with AD-2 resin and then applied to either HPLC or GC/MSD systems. With HPLC, $6.4{\sim}19.2\;{\mu}g/g$ of higenamine were detected from various Aconiti tubers and $182.3\;{\mu}g/g$ of higenamine from the embryo of Nelumbo nucifera. The results obtained with GC/MSD also provided comparable data with those obtained with HPLC.

Lymphangiosarcoma was described in a 2-year-old male Miniature Poodle. A 5 cm by 3 cm slightly elevated tan ventral abdominal mass was surgically removed with a wide margin and submitted for diagnosis. The mass has being grown rapidly during the last six months. On histopathology, the mass was composed of anastomosing channels or empty spaces which were free of red blood cells and lined by flat to plump pleomorphic neoplastic cells. The neoplastic channels or spaces were invasive into the surrounding fat and muscle tissues. Mild perivascular lymphocytic infiltration was also noted. Immunohistochemically, the neoplastic cells were positive to vimentin and Factor VIII. Based on histopathology and immunohistochemistry, the tumor was diagnosed as lymphangiosarcoma. Recurrence or metastasis was not noted so far after surgery.

Purpose of the present study was to clarify the role of noradrenergic neural activities in hypothalamus for either triggering or maintaining hypertension in deoxycorticosterone (DOCA)-salt hypertensive rats. Two groups of animals were prepared: 1) normotensive Wistar rats and 2) DOCA-salt induced hypertensive rats. Voltage dependent $^{45}Ca^{++}$ uptake, endogenous norepinephrine release, and the catecholamine content in the hypothalamus of DOCA-salt hypertensive and normotensive Wistar rats were compared. Animals at 4, 6 and 16 week-old of two groups were sacrificed by decapitation and hypothalamus was dissected out. Voltage dependent calcium uptake and norepinephrine release were determined from hypothalamic synaptosomes either in low potassium or high potassium stimulatory condition by using $^{45}Ca^{++}$ isotope and HPLC-ECD technique. Degrees of voltage dependent $^{45}Ca^{++}$ uptake and norepinephrine release in hypothalamic synaptosomes of 16-week-old DOCA-salt hypertensive rats were significantly greater than those of age matched normotensive control rats. The norepinephrine and dopamine contents of hypothalamus were about the same in two groups of animals. These results suggest that the alteration of evoked norepinephrine release related to calcium uptake in hypothalamus may play a role in the maintenance of hypertension in DOCA-salt hypertensive rats.

We previously observed that the transcription of some flagellar genes decreased in Salmonella Typhimurium tdcA mutant, which is a gene encoding the transcriptional activator of the tdc operon. Since flagella-mediated bacterial motility accelerates the invasion of Salmonella, we have examined the effect of tdcA mutation on the invasive ability as well as the flagellar biosynthesis in S. Typhimurium. A tdcA mutation caused defects in motility and formation of flagellin protein, FliC in S. Typhimurium. Invasion assays in the presence of a centrifugal force confirmed that the defect of flagellum synthesis decreases the ability of Salmonella to invade into cultured epithelial cells. In addition, we also found that the expression of Salmonella pathogenicity island 1 (SPI1) genes required for Salmonella invasion was down-regulated in the tdcA mutant because of the decreased expression of fliZ, a positive regulator of SPI1 transcriptional activator, hilA. Finally, the virulence of a S. Typhimurium tdcA mutant was attenuated compared to a wild type when administered orally. This study implies the role of tdcA in the invasion process of S. Typhimurium.
