The transit fare resulted from the renovation of public transit system in Seoul is basically determined based on the distance-based fare policy (DFP). In DFP, the total fare a passenger has to pay for is calculated by the basic-transfer-premium fare decision rule. The fixed amount of the basic fare is first imposed when a passenger get on a mode and it lasts within the basic travel distance. The transfer fare is additionally imposed when a passenger switches from one mode to another and the fare of the latter mode is higher than the former. The premium fare is also another and the fare of the latter begins to exceed the basic travel distance and increases at the proportion of the premium fare distance. The purpose of this study is to propose an algorithm for finding K number of paths, paths that are sequentially sorted based on total amount of transit fare, under DFP of the idstance-based fare policy. For this purpose, the link mode expansion technique is proposed in order to save notations associated with the travel modes. Thus the existing K shortest path algorithms adaptable for uni-modal network analysis are applicable to the analysis for inter-modal transportation networks. An optimality condition for finding the K shortest fare routes is derived and a corresponding algorithms is developed. The case studies demonstrate that the proposed algorithm may play an important role to provide diverse public transit information considering fare, travel distance, travel time, and number of transfer.

A 12-year-old female mixed Chihuahua dog was referred because of acute blindness and progressive tetraparesis. Mutifocal lesions in the cerebrum were noted on brain magnetic resonance images and cerebrospinal fluid analysis showed monocytic pleocytosis. Based on these results, granulomatous meningoencephalitis (GME) was strongly suspected. Cerebral lesions were definitely diagnosed as GME based on histopathological findings and positive results of immunohistological stains of brain with T-cell marker (CD3). This report describes the clinical findings, diagnostic imaging characteristics, and immunohistopathologic features of GME in an old dog. In addition, this case demonstrates that clinical signs of GME were mediated by perivascular infiltration of T lymphocytes and identification of causes in T cell-mediated inflammation should be further studied.

This paper describes the development of a wearable robot to assist ankle power for the elderly. Previously developed wearable robots have generally used motors and gears to assist muscle power during walking. However, the combination of motor and reduction gear is heavy and has limitations on the simultaneous control of stiffness and torque due to the friction of the gear reducer unlike human muscles. Therefore, in this study, Mckibben pneumatic muscle, which is lighter, safer, and more powerful than an electric motor with gear, was used to assist ankle joint. Antagonistic actuation using a pair of pneumatic muscles assisted the power of the soleus muscles and tibialis anterior muscles used for the pitching motion of the ankle joint, and the model parameters of the antagonistic actuator were experimentally derived using a muscle test platform. To recognize the wearer's walking intention, foot load and ankle torque were calculated by measuring the pressure and the center of pressure of the foot using force and linear displacement sensors, and the stiffness and the torque of the pneumatic muscle joint were then controlled by the calculated ankle torque and foot load. Finally, the performance of the developed ankle power assistive robot was experimentally verified by measuring EMG signals during walking experiments on a treadmill.

Purpose : The purpose of this study was to identify attitudes of hospice volunteers toward care of for terminally ill patients. Method : This was a descriptive study with a sample of 84 adults who were registered for a hospice volunteer education program at Severence Hospice Center. The Frommelt (FATCOD) scale on attitudes toward the care of the dying (Cronbach alpha=.778) and an open ended questions on "what if you only have 6 months to live" were used to collect the data. The data was analyzed using SPSS/W and content analysis. Results : 1) The hospice volunteers were mostly female, with an average age of 45 years, half of them were college graduates and their religious preference was Protestant. 2) The participants of this study demonstrated positive attitudes to care for the dying which is in coherence with hospice philosophy and principles. However they indicated difficulties in maintaining close relationships with people who are dying, and in communicating and sharing, and encouraging those who are dying to express their feelings. In the open ended questions, they identified that their most important issues would be guilt feelings toward their children, family concerns, and the burden of unfinished business in their lives. They also identified the fear of pain in the dying process and fear of the afterlife. The care they would like to receive was to have peace of mind, have a good listener, spiritual counselling, and pain relief and to be respected as a human being. The source of strength would be faith in God and they would like to overcome their of dying. The FATCOD scale has limitation in describing and identifying the need and attitude toward the care of the dying revisions were made. Conclusion : We all are the potential clients for the hospice rare. In a hospice volunteer education program, communication and interpersonal skill are essential. The fear of dying, afterlife, concerns about family with children, and human dignity are major concerns in hospice and palliative care.

Purpose: This study used a nonequivalent control group pre-post test design to analyze how a death preparation education program helps middle-aged adults deal with life and death anxiety. Methods: We studied 83 adults at the age of 40 to 65 years. An experimental group of 38 people participated in the death preparation education, and a control group of 45 people did not. The death preparation program comprising four sections was given for four hours per week, and the program ran for 11 weeks. Data were analyzed by descriptive statistics, t-test, ${\chi}^2$ test, Fisher's exact test, and ANCOVA using SPSS version 17.0. Results: The death anxiety score of the experimental group was significantly lower than that of the control group (P<0.000). The quality of life did not show significant difference between the experimental and control groups (P=0.188). Conclusion: It was confirmed that the death preparation education program is effective in alleviating death anxiety. Although the program was confirmed as a necessity for the middle-aged adults, repeated observations with a wider range of experimental group is needed to collect objective and solid data. Death preparation education for middle-aged adults is expected to be more widely provided, starting from local health facilities.

The prevalence of Bacillus cereus was determined in salad and Kimbab obtained from commercial retailers. Among the 100 salad samples analyzed, 54 samples were negative for B. cereus, whereas the bacterial count was < 10 colony forming units (CFU)/g in 8 samples, < 100 CFU/g in 25 samples, < 1,000 CFU/g in 11 samples, and > 1,000 CFU/g in 2 samples. The mean (standard deviation) was 1.18 log CFU/g (${\pm}0.71$ log CFU/g). In Kimbab, B. cereus was isolated from 20 samples; the mean bacterial count was 1.01 log CFU/g (${\pm}0.71$ log CFU/g). On the basis of the monitoring data, a statistical sampling plan was determined with the NEW sampleplan program (ICMSF), which was used as an analytical tool. To identify the most suitable sampling plan, the microbial limits (m, M) and the maximum allowable number of sample units yielding unsatisfactory test results (c) were varied, but the number of samples units, n = 5, was fixed. Sampling plans showing an acceptable probability (Pa) over 0.95 were considered suitable. Two plans (A and B) were finally suggested. Parameters for plan A are n = 5, c = 0, m = 1,000, and M = 10,000 and for plan B are n = 5, c = 2, m = 100, and M = 1,000. Interestingly, the latter plan was identical to the microbial sampling plan used in New Zealand. Thus, it was concluded that the suggested plan can be used as a sampling plan that is in line with international standards.

The purpose of this research is to investigate the types of name spectrum and their characteristics of domestic fashion brand names focusing on women' wear and bisex wear, and also studied the differences based on the sex of brand target. 224 of women's wear brands and 99 of bisex wear brands were selected from ‘2002 Korea Fashion Yearbook’ under the criterion that their brand names were made in Korea and they should engage in business in 2002. The data analysis quatitatively evaluate the frequency and qualitatively evalute the image of brand product and the meaning of brand name. The result as follows; 1.The domestic fashion brands for women's and bisex wear appeared to have to three types of name spectrum ; the descriptive name was the most frequently used one, then followed by the arbitrary, and the suggestive name. There were only one coined brand name and no generic brand name. 2. The characteristics of descriptive brand name was that, in most cases, it used the name of designer. For the suggestive brand name, it implied the features or the image of its products. For the arbitrary brand name, some bear the ideology or the foundation belief of company itself. 3. For women's wear, the discriptive name appeared most, and followed by arbitrary, and the suggestive name. For bisex wear, the suggestive brand name appeared most, and followed by arbitrary name, and the discriptive name. 4. For descriptive brand name, the names of designer were used most in women's wear brands. Otherwise, the brand names that directly described the image or the characteristics of products were used most in bisex wear brands. For suggestive brand name, soft and feminine images were prevailed in women's wear brand names but comfotable and casual images were dominent in bisexsual brand names. For arbitrary brand name, as the various types of languages were combined and the various meanings and words were mixed, and imply the various meanings in both cases, it was hard to classify the characteristics into some categories.

Recently a mobile service is changing into a system environment that offers the customer various contents service. Representative example of service is a Calling Identity Del ivory Service(CID). Such service has the problem in the case which the receiver cannot remember the phone number of the sender; it has a difficult problem that cannot easily confirm whose the phone number it is. Therefore, it is desirable to design and implement visual services that can enhance the recognition of users. In this paper, we propose the architecture that is similar to a Calling Identity Delivery Service. We propose the architecture for communication service and system that is able to visually display the information of the sender using 2D image data in mobile environment. After that we set the image information to represent the user and this method is able to visually display the information of the sender by transmitting an image data through channels from switch station or base station using the server. When the receiver receives a phone call from the sender, this method provides an efficient service by transmitting visual data with bell sound. That is, the image information of sender is appeared on liquid crystal display(LCD) of the receiver at the same time. We investigate the concepts for processing real-time transmission of image data and describe an example of the implementation result that is based on system. This technology has a potential influence on the marketing and presents an efficiency of this method.

This study was conducted to figure out the influential factors on premenstrual syndrome(PMS) of college female students which are to be utilized as the basic data to develop and apply programs for preventing and controlling such symptom. The subjects were 330 college female students. The data were collected from April 2, 2012 to April 6, 2012. From the results, There has been significant correlation between stress and PMS(r=.36, p<.001) and the attitude to menstruation has appeared to have significant positive correlation with PMS as well(r=.34, p<.001). Multiple regression analysis has been employed to identify the influential factors on PMS and the result has shown that menstrual attitude, grade point average for stress, smoking and dysmenorrhea have been the most significant influential factors with 27% of explanatory power. The level of significance has been high in menstrual attitude(${\beta}$=.28, p<.001), grade point average for stress(${\beta}$=.27, p<.001), smoking(${\beta}$=.20, p<.001) and dysmenorrhea(${\beta}$=.15, p<.001) respectively. In conclusion, it needs to find nursing interventions for PMS related to psychosocial factors and suggest a narrative study for improving quality of life of women with PMS.
