Background: The present study was conducted to determine knowledge level of technicians working in hospitals about testicular cancer (TC) and self-examination of testicles (TSE) and to determine levels of consciousness and implementation status about TSE. Materials and Methods: This cross-sectional study was conducted with technicians working in hospitals (n=243) between $2^{nd}$ January-$31^{st}$ May 2012 at private and governmental hospitals in urban Kayseri. Healthy control subjects (n=235) who were similar to technicians in terms of age, education level and income status were also included to the study. Chi-square test was used in comparison of categorical variables. Results: Technicians were significantly more aware of TC than controls, but the latter were found to have significantly more information about TSE. There was no significant difference between the two groups in terms of knowing how to do TSE and 80% of both groups were unaware this exam. Of technicians, 19.8% and of controls, 25.5% did TSE, the difference being statistically insignificant. First reason for not doing TSE was "not-knowing" among technicians (48.1%) while it was "ignorance" among controls (66.8%). Of technicians doing TSE, 37.5% did as it came to their mind while 51.7% of controls performed TSE several times in the previous year. Technicians were significantly more afraid of getting TC than controls (p=0.037). Conclusions: It was determined in the present study that rates of TSE were similar between technicians and controls. However compliance with the recommended frequency and right method was low. Consequently, public health education should be planned and applied in order to increase the knowledge of TC and TSE.
Purpose. This study was tried to compare the effect of the change in postural deviation caused by the pain side Subjects and Methods. Inpatients and outpatients (n=71) were selected from I hospital who have a musculoskeletal low back pain and shoulder pain without any history of the central nervous system (CNS) lesions, orthopaedic problems of the both lower extremities, or the vestibular and the visual default. For the control group, normal and healthy subjects (n=30) were selected without any history of weight bearing disorders. the weight bearing was rated by the computerized force plate. Results. 1) Postural deviation was not significant difference between patients and control group(p<0.01). But postural deviation in patients was more pronounced than control group. 2) There was significant difference of postural deviation between in patients according to the pain side(p<0.01). When the pain side was on the left side, postural deviation tended to the right. When the pain side was on the right side and vertebral body, postural deviation tended to the left. 3) There was no significant difference of postural deviation between regional pain in shoulder and regional pain in low back(p<0.01). Discussions and Conclusion. As a result, the pain, for sure, affected the good posture and its keeping process directly or/and indirectly. Therefore, as the postural deviation increases, the additional energy consumption increased by the works of the muscles to keep the good posture. Preponderated postural deviation, furthermore, could load too much to the musculoskeletal system, leading to increase the pain. The postural deviation, a result of the pain, can cause a secondary deformity of the distal area as a compensatory reaction, and this compensation actually become a cause of the musculoskeletal symptom back in a cycle. Therefore, the appropriate treatment of the musculoskeletal problem and the education of the posture correction should be given to decrease the pain, preventing the secondary deformities, and increasing muscle energy efficiency of the posture remaining muscles.

The Russian ratsnake, Elaphe schrenckii, is found in Russia, China, and Korea, and is considered to be an endangered species by the Ministry of Environment in South Korea. Due to habitat loss and use in oriental medicine, their population has been severely decimated. In South Korea, two subspecies of E. schrenckii has been defined according to body color: E. s. schrenckii (blackish) and E. s. anomala (yellow-brownish). Molecular genetic studies on Elaphe schrenckii are very scarce and the taxonomy of Elaphe schrenckii subspecies is uncertain. From the present study, we attempted to identify the genetic differences of these two subspecies using species-specific microsatellites developed from the genomic library of E. schrenckii. Nine polymorphic loci were tested on 19 individuals from E. s. schrenckii (n=10) and E. s. anomala (n=9) in South Korea. The mean number of alleles was 3.78 in E. s. schrenckii and 4.11 in E. s. anomala. The average expected heterozygosity was 0.542 and 0.511 in E. s. schrenckii and E. s. anomala, respectively. We found a lack of genetic structure between two subspecies ($F_{ST}=0.016$) and no genetic discrimination between two subspecies was found. Based on the present findings by microsatellites, two subspecies can be considered as one species, E. schrenckii. However, further investigations on taxonomical status using mitochondrial and nuclear DNA sequences need to be performed and morphological & ecological data should be revised. The genetic markers should benefit future studies of the endangered species of other Elaphe species for the study of genetic diversity and potential conservation management.

Objective : The aim of this multicenter, matched-pair study was to compare the outcomes of stereotactic radiosurgery (SRS) and conventional external radiation therapy (RT) when used as a primary treatment in spine metastasis from hepatocellular carcinoma (HCC). Methods : From 2005 to 2012, 28 patients underwent SRS as the primary treatment in spine metastasis from HCC. Based on sex, age, number of spine metastasis, Child-Pugh classification, interval from original tumor to spine metastasis, and year of treatment, 28 patients who underwent RT were paired. Outcomes of interest were pain relief, progression free survival, toxicities, and further treatment. Results : The perioperative visual analog scale (VAS) decrease was larger in SRS group than in RT group, but the difference was not significant (3.7 vs. 2.8, p=0.13). When pain medication was adjusted, the number of patients with complete (n=6 vs.3) or partial (n=12 vs.13) relief was larger in SRS group than in RT group; however, the difference was not significant (p=0.83). There was no significant difference in progression free survival (p=0.48). In SRS group, 32.1% of patients had 1 or more toxicities whereas the percentage in RT group was 63.0%, a significant difference (p=0.04). Six SRS patients and 7 RT patients received further intervention at the treated segment. Conclusion : Clinical and radiological outcome were not significantly different between the two treatments. Toxicities, however, were more prevalent in the RT group.
The morphology is described of a post larva of Pomacanthus xanthometopon of the family Pomacanthidae collected in the West Pacific ($26^{\circ}9'N$, $125^{\circ}0'W$) on May 5, 2001. The specimen is moderate to deep bodied and laterally compressed. Body depth is 66.3% of body length at 8.0 mm BL. The body is covered with small spine groups, each composed of two to four spines. The anus located at a vertical through the 8th or 9th dorsal fin spine. There is no strong spine at the angle of the preopercle that appears in the adult stage. Small pigments are spread dorsally on the head, upper trunk and over the membrane of dorsal fin, from the 1st to 11th ray.
Although attachments have been utilized for a retainer of removable prostheses during several decades, there is little information on the force distribution by the attachments. This study was undertaken to evaluate the stress patterns developed by partial dentures employing rigid attachments on the supporting structures. Four types of the mandibular removable partial dentures were designed depending upon the position of the rigid attachment and the existency of lingual bracing. Under 100N of vertical and 25N of lateral loads on the 1st and 2nd lower molar of partial denture, stress distribution patterns and displacement were analysed with three dimensional finite element method by ANSYS version 5.3. 1. The highest stresses were concentrated on the distal alveolar crest of posterior abutment and the second stresses on the apical region of posterior abutment in the models. 2. The greatest displacement were shown on the distal alveolar crest of posterior abutment and the second displacement on the distal alveolar crest of anterior abutment in the models. 3. There was little difference between the models with intraoral attachment and those with extracoronal attachment. 4. There was little difference between the models with and without the lingual bracing.
542 periodontal patients having early-onset periodontitis(EOP) have been reclassified into a more homogeneous phenotypic subsets by newly revised radiographic criteria. Representative patients of each EOP subform have been examined of serum IgG subclass antibodies against periodontopathic bacteria, Porphyromonas gingivalis(Pg) 381 and of genetic markers for IgG allotypes to clarify the relationship between these parameters and phenotype expression of each subform. The early onset periodontitis could be reclassified by the radiographic parameters combining the mean interproximal alveolar bone loss(BL) and the radiographic ratio(between 1st molars and the adjacent teeth: Ratio) with statistical significance(p<0.001 by MANOVA). Moreover these EOP subforms could clearly be delineated from adult periodontitis. Of subform I and II(localized type EOP) patients with minimal mean bone loss(BL<5.0), patients demonstrating disease activities in localized areas(Ratio.>1.5) showed the elevated responses in all the IgG subclasses against Pg compared with those of patients without disease activity(Ratio <1.5). There were gradual increase in the IgG2 and IgG4 titers against Pg as the disease developed into the generalized forms suggesting the possible role of these antibodies in modulating the phenotype expression. The genetic marker study for IgG allotype revealed that mean IgG2 and IgG4 subclass titers were significantly higher(p<0.01, p<0.05, respectively) in patients who were positive for G2m(n). This indicated that IgG subclass responsiveness against the bacterial antigens are under the immnuogenetic control. The observed frequencies of G2m(n) were significantly higher (p<0.05) in subfrom IV patients who had the characteristic features of classical rapidly progressing periodontitis indicating the possible genetic predisposition in these patients.

In this paper, A high selective dual-band bandpass filter was proposed using a dual-mode ring resonator with two short-circuited stubs. For dual-mode resonance, the ring resonator is directly connected with non-orthogonal feed-lines via coupling capacitors. Two short-circuited stubs which are unequal lengths are simultaneously placed at two corners along the two symmetry plane of the ring resonator in order to obtain dual-band responses. Because the feeding angle perturbated ring resonator of the proposed dual-band bandpass filter has the symmetrical structure, Even/Odd mode analysis can be well applied to extract the scattering parameters and transmission zero frequencies. The proposed dual-band bandpass filter was designed and fabricated for WLAN(Wireless Local Area Network) application of IEEE 802.11n standard. The measured results showed a good agreement with the simulation results, and it should be well applied not only for WLAN applications but also for any other communication systems.

Objectives: The purpose of this study was to investigate the effectiveness and safety of ginseng seed oil in healthy subjects who have mild liver dysfunction. Methods: A randomized, double blinded, placebo-controlled trial was conducted. A total of 167 subjects visited Semyung University Hospital from July 1st, 2016 to June 10th 2017. Except for the 103 excluded subjects, 64 subjects were randomized into one of the two groups: an treatment group(n=33) and control group(n=31). Subjects were randomly given either ginseng oil seed capsules or indistinguishable placebo capsules(2 capsules per dose, twice per day). Laboratory tests(aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, triglyceride, total cholesterol, high density lipoprotein-cholesterol, low density lipoprotein-cholesterol) were performed to evaluate the effectiveness after 6, 12 weeks of treatment. Vital sign, laboratory test were performed to assess safety at every visit. Results: There were no significant differences in efficacy between treatment group and control group. There were some adverse events with no significant difference in symptoms and frequency between treatment group and control group. Conclusions: Although the efficacy of ginseng seed oil was not proved, ginseng seed oil did not worsen liver function and proved its safety. More study of ginseng seed oil and clinical trials are necessary to increase the usefulness of above-ground parts of ginseng.
The effects of fetal number (single or twin) on blood glucose and plasma NEFA during pregnancy and around parturition were studied on ten Alpine ${\times}$ Beetal crossbred goats in their first to third lactation. The animals were divided in-groups 1(carrying single fetus, n=4) and 2(twin fetus, n=6). The samples were drawn on day1 after estrus and then at 14 days interval (fortnight) for 10 fortnights. Around parturition the samples were taken on days -20, -15, -10, -5, -4, -3, -2, -1 prior to kidding and on day 0 and +1, +2, +3, +4, +5, +10, +15, +20 days post kidding. In twin bearing goats the blood glucose concentration continued to increase from 1st until 4th fortnight and thereafter gradually decline from 5th upto 8th fortnight. In single bearing goats there was increase in levels from 2nd upto 4th fortnight and thereafter it declined from 5th uptill 9th fortnight. The difference in sampling interval was highly significant (p<0.01) in both the groups. However the values were higher in single than in twin bearing goats. The plasma NEFA concentration was low in both the groups' upto 4th fortnight and thereafter it is continuously increased upto 9th fortnight. During prepartum period the blood glucose was higher in single than in twin bearing goats. The values were minimum on the day of kidding in both the groups. During postpartum period the values were significantly (p<0.01) higher in twin than in single fetus bearing goats. The plasma NEFA was significantly (p<0.05) higher in twin than in single fetus bearing goats. The blood glucose and plasma NEFA concentration can be used as index of nutritional status during pregnancy and around parturition in goats.
