  • Freshwater fish fauna and community structure were investigated at thirty seven stations in the Yeong river, Nakdong river system, Korea from March to October 2013. During the surveyed period thirty nine species and two types belonging to thirteen families were collected. In this collection fishes of Cyprinidae were most numerous possessing 61.0% of all. There were seventeen Korean endemic species including Acheilognathus koreensis, two endangered species such as Koreocobitis naktongensis and Microphysogobio koreensis and two exotic species such as Oncorhynchus mykiss and Micropterus salmoides. Fish species transferred from other native rivers were three species such as Opsariichthys uncirostris amurensis, Pseudobagrus koreanus and Hypomesus nipponensis. Dominant species based on the number of individuals was Zacco koreanus NS (23.24%) and sub-dominant species were Z. koreanus NE (12.72%) and Z. platypus R (12.35%). The community analysis revealed that the structure of fish community in the Yeong river was very stable and diverse in having diversity 1.134, evenness 0.703, dominance 0.110 and species richness 4.348. Fish community was divided into four groups based on similarity indices among surveyed stations such as upper reach, mid-upper reach, middle reach and lower reach group.

  • Redox complexes to transport electrons from enzyme to electrodes are very important part in glucose sensor. Pentacyanoferrate-bound aniline ($Fe(CN)_5$-aminopyridine), was prepared as a potential redox mediator in a glucose dehydrogenase (GDH)-glucose sensor. The synthesized pyridyl-$NH_2$ to pentacyanoferrate was characterized by the electrochemical and spectroscopic methods. A amperometric enzyme-linked electrode was developed based on GDH, which catalyses the oxidation of glucose. Glucose was detected using GDH that was co-immobilized with an $Fe(CN)_5$-aminopyridine and gold nano-particles (AuNPs) on ITO electrodes. The $Fe(CN)_5$-aminopyridine and AuNPs immobilized onto ITO electrodes provided about a two times higher electrochemical response compared to that of a bare ITO electrode. As glucose was catalyzed by wired GDH, the electrical signal was monitored at 0.4 V versus Ag/AgCl by cyclic voltammetry. The anode currents was linearly increased in proportion to the glucose concentration over the 0~10 mM range.

  • The purpose of this study was to find the characteristics of the frontal natural head position(NHP) of patients with facial asymmetry, and to contribute to the diagnosis of facial asymmetry in the clinical examination of orthodontic patients. Twenty adult patients who had apparent facial asymmetry and no severe sagittal skeletal discrepancy were selected as the asymmetry group, and 21 young adults who had symmetric faces were selected as the symmetry group. Frontal cephalograms were obtained in the state of NHP using a pivot-mounted fluid level device. The degree of the menton deviation was defined as the angle between the line drawn through crista galli and anterior nasal spine and the line drawn through crista galli and menton. The following angles were measured and each of them was compared with the degree of the menton deviation one is the angle between the true vertical line and the supra-orbital line which is a tangent line to the extreme cranial point on the supra-orbital margin, and the other is the angle between the true vertical line and the cervical line drawn through the midpoint of atlas and the 4th cervical vertebra. Through the statistical analysis, following results were obtained. 1. The angle between the supra-orbital line and the true vertical line was much mote deviated from the right angle in the asymmetry group than in the symmetry group. 2. The angle between the cervical line and the true vertical line in the asymmetry group showed greater tendency than in the symmetry group, but the difference was not statistically significant. 3. In the asymmetry group, the degree of the menton deviation was positively correlated with the angle between the supraorbital line and the true vertical line. The above results suggest that racial asymmetry patients show the tendency to have the tilted NHP to compensate the deviation of menton position.

  • As the privacy issues are all around the world, the intrusion into personal privacy is concerning. For that reason, government established the article from the personal information protection law that has to notice the privacy policy to users on the online site. and the matter of privacy invasion make concern toward behavior of online user. Although there are rules to carrying legal binding force in accordance with, because it is full of text and uncomfortable to read so that its readability is low. In the same context, each other has different state of understanding with the policy for personal information has been playing an important role. In this approach, companies and government do not think this over deeply and do just for what their practical use is. That is the reason why this research start, and the result expecting for real. As the result in the participant who cognize the privacy policy display pattern, they have certain type to do. In this article, the certain behavior doing is remarkable with the privacy policy. According to privacy concern, privacy fundamentalist reveals such a compromise reaction to protect their information when they know what information which the privacy manager of service provider collect. This study arrives at the result depending on the gap of privacy group that the group of checking the policy contents, especially the group which has high privacy concern, they move forward to protect their emotion and put a constructive plan into protective action. Otherwise, the group of unchecking the policy contents and following their own thinking of privacy policy are not deemed statistically significant. Therefore, this is considered to support more various implications than the previous issues and alternatives about privacy policy pattern and user protection behavior of privacy.

  • This research proposes new tram signal coordination model, called MAXBAND MILP-Tram for a passive tram signal priority strategy. The proposed model was formulated based on the MAXBAND model that was a traditional arterial signal optimization model. The model could calculate the bandwidth solutions for both general-purpose-lane traffic and median-tram-lane traffic. Lower progression speed are applied for the tram traffic considering lower running speed and dwell time at the stations. A phase sequence procedure determines the green times and left-turn phase sequences for tram traffic in median tram lane. To estimate the performance of the MILP-Tram model, the control delay of trams were estimated using the micro simulation model, VISSIM. The analysis results showed 57 percent decrease of the tram compared to the conventional signal timing model. The delay for car, however, increased 18 percent. The sensitivity analysis indicated that the passive tram signal priority strategy using the offset and phase sequence optimization was effective in reducing the person delay under the congested traffic condition.

  • This study suggested implications by dividing the concept of brand origin into national image and manufacturing capacity image, verifying the direct impact of these variables on brand trust and brand loyalty, and verifying the difference between products with the effect on brand trust of brand origin, which is the result of verification. The specific implications of this paper are as follows. First, brand origin does not directly affect brand loyalty, but it can have a direct impact on the preceding variable, brand loyalty. This study may conclude that it is desirable to define the factors that affect the purchase selection indirectly through the assessment of product properties or positive effects on brand image rather than having a direct impact on product purchase or selection. Second, the difference in brand origin influence by product characteristics was very evident. Past studies were limited to a few products, so pan-product testing was not conducted, and the empirical power was judged to be limited, so this study included a variety of products and tried to detect differences between products through actual empirical research. Involvement and self-congruity have been presented with results that can be judged as important variables for brand origin to affect brand performance and variables. Looking at the role of the brand origin for each product characteristic by distinguishing between product characteristics and whether or not products related to quality, history, authenticity, etc., the product recognized as high quality and the product recognized as having high integrity showed higher effect of the brand origin, but history was a product characteristic that did not show the effect of the brand origin.

  • We studied the actual condition of work environment and work morale according to the type of employment of service workers by using the raw data of the Fourth Work Environment Survey (2014) conducted by the Institute of Occupational Safety and Health. In this study, the condition of work environment were composed of work posture, emotional labor, and work autonomy. Also, dimensions related to work morale were composed of competence, job satisfaction, social support, and job stress. In addition, the employment was classified into three types of regular workers, temporary workers, and daily workers. The results showed that temporary and daily workers were more likely to work in a less favorable environment than regular workers, and there was a close correlation between work environment and work morale. Based on this study, it is possible to know about the actual situation and problems of the service workers, and it is hoped that company can search for measures to increase the working environment and work morale of the workers in order to provide better service.

  • The purpose of this study was to examine the effects of a mentoring program designed to assist nursing students adjust to life in college and strengthen their leadership abilities. The mentoring program consisted of nine sessions including information on basic mentorship functions, as well as the results of similar previous studies. This was a quasi-experimental study with a non-equivalent control group pre-post test design in order to evaluate the results of this program. Mentoring and data collection were performed from March 3 to May 30, 2014. The experimental group participants included 20 mentee students (in grades 1 and 2), and 20 mentors (in grades 3 and 4). Both pre and post tests were administered before and after the mentoring program. The score for "adjust to life in college" was more significantly increased in the mentee student experimental group as compared with the control group. Similarly, the post test score for "leadership" was more significantly increased from the pre test score in the mentor student experimental group. However, no statistically significant differences were found for the post-pre test "leadership" score between the mentor student experimental group and the control group. These results suggested that mentoring had a significant effect on the ability of nursing students to adjust to life in college, as well as to strengthen their leadership abilities, and the program needs more developed contents for leadership.
