보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

Staphylococcus aureus is considered one of the most frequently occurring community- and hospi-tal-associated pathogens. Infectious diseases caused by Staphylococcus aureus are in various forms, ranging from mild skin infection, endocarditis, to fulminant septicemia. The purpose of this study was to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage rates among nursing students. The relevant data were collected using a questionnaire, and microbial samples were collected from the nasal cavities of 215 nursing students. From the collected specimens, strains of Staphylococcus aureus were isolated and subjected to antibiotic susceptibility tests. Of 215 students, 62 (28.8%) were nasal carriers of Staphylococcus aureus, and three students (1.4%) were nasal carriers of MRSA. None of the three students with MRSA had any history of hospitalization over the past 12 months and had not provided nursing care for MRSA patients. However, two students among these three had received antibiotics. All MRSA isolated from these three students were mupirocin-sensitive. According to the results, the rates of MRSA nasal carriage among the nursing students were lower than those of patients or other healthcare workers. Thus, routine screening for nasal MRSA culturing is not recommended in students who practice in the clinic. However, students should be educated about infection control in order to prevent practice-related MRSA nasal.

The purpose of this study was to provide essential data for treatment by analyzing the characteristics of patients with alcohol dependence and the relationship between depression and alcohol dependence. The subjects were 58 patients with alcohol dependence aged 20–70 in a psychiatric hospital. The Alcohol Dependence Scale (ADS) and Beck Depression Inventory (BDI) were used as assessment tools. The collected data were analyzed using SPSS WIN 21.0: a one-way ANOVA was conducted to examine differences in alcohol dependence contingent on the degree of depression and a Pearson's correlation coefficient was calculated to determine the relationship between depression and alcohol dependence. According to the study results, the majority of participants were in their 40s or younger; 35 participants (60.3%) were high school graduates and 19 participants (32.8%) earned more than 2 million won and less than 4 million won. There were significant positive correlation between depression and alcohol dependence (r=.283, p= .031). Alcohol dependence was significantly higher as the degree of depression increased: normal (16.67±13.99), mild depression (18.40 ±11.55), moderate depression (28.00 ± 17.74) (F= 3.99, p= .024). In conclusion, those with severe depression were highly dependent on alcohol and intervention for depression should be incorporated into future treatment for more effective alcohol disease management.

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

The purpose of this study cares to investigate effect of shoulder stabilization exercise at the pain control, function and range of motion of shoulder girdle after surgery of shoulder dislocation patients. The subjects were 30 patients who operated on capsulorrhaphy surgery of shoulder dislocation patients. They were assigned by random sampling to an experimental group (n = 15) to which stabilization exercise was applied and a control group (n = 15) to which ordinary physical treatment was applied. To evaluate the degree of pain prior to and after the treatment, a 100 mm visual analogue scale (VAS) was used. The Constant–Murley Scale (CMS) and simple shoulder test (SST) was used to determine the function and condition of the shoulder joints of the subjects. To determine the range of motion, a Dartfish program was used. The results of comparison of the therapeutic effect in the experimental and control groups revealed significant differences in active abduction, SST, and power component of the CMS. The results suggest that shoulder stabilization exercise positively affects pain alleviation and functional recovery in shoulder dislocation patients.

Nail Color and Texture Analysis for Disease Detection

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

In this paper we are elaborating the concept of disease detection in the human body using the nail image of human fingers and analyzing the data from the image on the basis of nail color and texture. Fingernail has to be detected from the entire hand region using distribution density of the nail color pixels on the surface of nail. The methodology for creating a finger nail detection system involves removing the skin area from shiny/glossy nail portion; this is known as image segmentation concept that separates the specific object. Image segmentation is the method of dividing the image pixels into homogenous region.

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

A hierarchical system of wireless USB (WUSB) over wireless body area networks (WBAN) is adopted for wearable health-monitoring systems (WHMS). It is executed on the basis of WUSB over WBAN protocol at each wearable sensor node comprising the WHMS. Basically, a single WHMS operates based on WUSB over WBAN protocol. And the multiple WHMSs operate based on the WiMedia D-MAC protocol and dual-role device (DRD) function. In this paper, a multimedia streaming scheme for N-screen services is proposed for WHMS networks. In a hospital, N-screen applications must be required by using WHMS networks. The multimedia streaming scheme for N-screen services is composed of service interval-based resource allocation and multicast reservation schemes. In simulation results, efficiency of the multimedia streaming scheme is proven through throughput and delay performances at an N-screen service scenario.

Comparative Analysis of Signals Acquired Before and After the Place of Articulation

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

Communication is a key factor in a developing society. It is usually carried out by using signals that come from the brain, and then produced as sounds in the Place of Articulation. An alternative to this type of communication is subvocal speech or “subvocalization”, which consists in the acquisition of the signals produced in the cerebral cortex and their analysis before the voice production process in the Place of Articulation is made. This paper proposes a prototype system for acquisition of the signals produced in the Place of Articulation; by using a Data Acquisition System (DAS) and MATLAB® as a tool for comparing the obtained results.

Workload and Work Importance of Clinical Research Nurse

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

This study was conducted to investigate the workload and work importance of Clinical Research Nurses (CRNs). Subjects consisted of 152 CRNs. The mean scores were 4.79/7 points in workload; 5.75/7 points in work importance. Workload differed significantly according to their job-related characteristics, depending on the type of employment (p=.027), the number of ongoing studies (p=.027), while there was no statistically significant difference in their work importance according to their job-related characteristics. These findings indicated that, in order to increase CRN’s job satisfaction, it is necessary to understand their job related characteristics, well and to prepare a work environment for effective job performance along with standardized job analysis.

Effects of Olibanum Extracts on Collagenase Activity and Procollagen Synthesis in Hs68 Human Fibroblasts and Tyrosinase Activity

보안공학연구지원센터(IJBSBT) 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.5

This study was designed to investigate the collagen metabolism and tyrosinase activity of Olibanum extracts (OE). The currently known effects of OE are to move blood, calm pain, solve oedema, and promote tissue regeneration. The effect of OE on type I procollagen production and collagenase (matrix metalloproteinase-1, henceforth referred as MMP-1) activity in human normal fibroblasts Hs68 after ultraviolet B (UVB, 312 nm) irradiation was measured by the ELISA method. The tyrosinase activity after treatment with OE was measured as well. There was no cytotoxicity at all tested concentrations. OE significantly inhibited the increased collagenase activity after UVB damage, whereas it did not recover the reduced type I procollagen production in UVB damaged Hs68 cells. It did not reduce the tyrosinase activity and the L-DOPA oxidation, either. In conclusion, OE showed the anti-wrinkle effects via the collagenase inhibitory mechanism. Although further research is needed to validate its efficacy, these results suggest that OE may have potential as an anti-aging ingredient in cosmetic herb markets.
