  • The purpose of this study is to establish shipping companies' selection factors related to a classification society and to explore the relative importance of each factor using the analytical hierarchy process(AHP) technique. Insufficient research exists on the hierarchial structure of shipping companies' factors of selecting a classification society. The factors are identified and classified into two tiers of major and detailed factors, by referring to the related industrial linkages, prior research related to the determinants, and the process and service delivery of the classification society's activities. The empirical analysis of this study is based on the relative importance of determinants when selecting a classification society, and experts engaged with shipping companies were surveyed using questionnaires. The results of the AHP methodology on the main factors of shipping companies in selecting a classification society are as follows. The relative importance of the main factors was 0.373 for technical and survey services, 0.284 for recognized organizations(RO) functions, 0.177 for cost and 0.167 for market(related industry) expectations. The relative importance of the detailed factors is 0.144 for the ability to respond to a port state control(PSC) inspection, 0.143 for technical services, 0.090 for the requirements of financial institutions/ shippers/shipyards, 0.087 for class maintenance costs, 0.086 for the survey network, 0.085 for surveyor competency, 0.072 for cooperation with IMO and government authorities, 0.067 for recognition for RO, 0.058 for the business power of the classification society, 0.052 for the initial inspection costs, 0.040 for reputation and trustworthiness, 0.038 for the costs related to the class, and 0.037 for connections to related industries.

  • As recent information communication technology is rapidly developed, a lot of researches related to speech signal processing have been processed. So pitch period is applied as important factor to many application fields such as speech recognition, speaker identification, speech analysis and synthesis. Therefore, many algorithms related to pitch detection have been proposed in time domain and frequency domain and AMDF(average magnitude difference function) which is one of pitch detection algorithms in time domain chooses time interval from valley to valley as pitch period. But, in selection of valley point to detect pitch period, complexity of the algorithm is increased. So in this paper we proposed pitch detection algorithm using rotation transform of AMDF, that taking the global minimum valley point as pitch period and established a threshold about the phoneme in beginning portion, to exclude pitch period selection. and compared existing methods with proposed method through simulation.

  • This study examines the importance of location and transportation in the operation of small- and medium-sized hospitals in the rapidly changing clinical environment. Approximately 350 persons were surveyed for approximately 40 days from July-August 2017, and responses were analyzed using SPSS and AMOS Statistical Package for 335 parts excluding 8 parts of 343.The main research results were as follows: First, a hypothesis was adopted that the attractiveness of building materials will positively affect customer satisfaction. Second, the hypothesis that transport infrastructure has a significant impact on customer satisfaction was rejected. Third, the hypothesis that the building appeal will positively affect the site was supported. Fourth, the hypothesis that transport infrastructure will have a significant impact on location marketability was supported. Fifth, the hypothesis that location marketability will significantly impact customer satisfaction was supported. Sixth, the hypothesis that the relationship between the site and customer satisfaction with the relationship between the client and the client is explained is partly attributable to the fact that there is a partial function. The assumption that the relationship between traffic infrastructure and customer satisfaction was confirmed. The hypothesis that the relationship between traffic infrastructure and customer satisfaction was supported. This research focuses on small- and medium-sized hospitals located in Seoul, which does not include the recognition of patients' awareness of the location and transportation of small- and medium-sized hospitals. Moreover, this study has the limitation in analyzing patient satisfaction, rather than the objective data of the financial management performance of the hospital. The results of this study could provide the basis for selecting the future locations of health care facilities.

  • This study examined the change in the students' perception of infection after school education. A self-reported questionnaire was filled out by 300 dental hygiene students in Kangwon from December 3 to December 4, 2016. The contents of the questionnaire included the general characteristics (5 items), infection-related selection (2 items), infection control recognition (5 items), and infection control behavior (10 items). The data were analyzed by frequency analysis, t-test, one way ANOVA, Chi-square test, and hierarchical multiple regression analysis using SPSS 24.0. The Cronbach's Alpha was 0.941 and 0.658, respectively. The school year and hospital practice experience had some influence on the change in infection recognition. A total of 127 students (62.6%) who had experience in practicing in hospitals knew more about antibodies. Hand washing was the highest in personal protection, followed by masks. The selection of the infectious control education method showed that the practical training class was high irrespective of the hospital practice experience, and the perceptions of patient-related infections were the greatest explanatory factor in perception after education.

  • This study was conducted from March 15 to March 19, 2019. The purpose of this study was to examine the recognition of uniforms and their images for the selection and development of uniforms and the pursuit of images for dental hygienists and students in some regions. Study methods included frequency analysis, factor analysis, reliability analysis, ANOVA, chi-squared test, and regression analysis. The collected data was analyzed using the IBM SPSS Statistics 21.0 program. This study found that students majoring in dental hygiene thought that uniforms influenced their image and that they influenced the image of the hospital. In addition, students who experienced clinical practice preferred the pants type to the uniform type and the color to achromatic color. In addition, these students preferred scrubs and the use of Crocs for shoes. The results of this study showed that dental hygiene students considered image transmission through uniforms as important. However, it appears that they prefer practical uniforms and shoes over uniforms that convey external images. This is a part that makes us aware of the need for changes in training clothes and training. In conclusion, it is necessary to develop a practical uniform while expressing the image of the institution, which will be reflected in future dental uniform selection.

  • Dietary life is said to be consummated even to a phase of art from phase of survival, recognition, selection and preference. Dietary life, from a sheer earing, is now transforming itself into a joy, and therefore, function of foodstuff packaging demand diversification rather than a simple packaging. Recently, socio-economic environment is showing conspicuous changes in that there are increasing number of working couples nuclear family, old-age population, social activity and improvement of living standards. Such a change in the living environment has much impact on our dietary life. Particularly, an age when cake and cookies of western origin were all but strange is gradually phasing out, while it is deemed to be improper to overlook the fact that bread and cakes are solidifying their position as part of foodstuff meanies for on dietary life. Of cakes and cookies, cakes have come to enjoy a position whereby they are regarded as part of an imperative for family banquets, various get-together and birthday celebration, etc., with a significant improvement that caters to our taste vis-a-vis an stage of introduction of cakes. At the time when reined foreign bakeries, one after another , are contemplating to make an inroad into Korea, and when the distribution market is to be opened fully in July of 1993, Korea bakeries that have been building up their position within the domestic market are expected to face a considerable number of difficulties. Accordingly, under such circumstances of the time text we are in it is attempted in this study to map out measures that may contribute to the strengthening of the products of business enterprises and improvement of corporate image that may appeal to feeling and emotions of consumers packaging that could attain objectives, and package design planning that, as an important factor for playing its own share in the restoration of humanism that is being alienated, may appeal to consumer sensitivity, rather than packaging that is being utilized merely as tool designed for marketing

  • As Korea has approached the aging society, older Koreans have become an important force in restaurant sales today. To succeed with this silver market, it is important for restaurant managers to know who they are and which factor influence the older Koreans' eating-out decision making process. The purpose of this study was to investigate the effect of the elderly consumers financial independency on restaurant selection process. Data were collected from 178 older consumers above 55 years old and analyzed using the descriptive statistic analysis, MANOVA, and one-way ANOVA. The results showed that the elderly consumers financial independency significantly influenced the decision making process in determining where they eat out Significant differences were found between high income group and low income group in the Problem Recognition Step(Wilks' Lambda=0.776, F=3.796), Information Search Step(Wilks' Lambda=0.779, F=2.959), Alternative Evaluation Step (I :Wilks' Lambda=0.835, F=1.748/ II :Wilks' Lambda=0.764, F=3.212), and Purchase Decision Step(Wilks' Lambda=0.849, F=2.412), except the Post-Purchase Behavior(Wilks' Lambda=0.933, F=1.179). The more financially independent older consumers were, the more directly they were involved in the eating out decision making process. Older consumers with higher income and more personal property were likely to 'propose to eat out by themselves'(F=10.986), to obtain restaurant information from the 'printed materials'(F=9.707), to consider 'convenient location' as most important factor when they eat out(F=5.594), and to go to 'family restaurant'(F=7.067), 'Japanese restaurant'(F=7.391) and 'fine dining restaurants'(F-=6.382). In conclusion, we found that the elderly consumers financial independency did influence the eating-out decision making process. Considering that older Korean will become a financially independent consumer and will be eating away from home more often, food service operations should actively position themselves for this market and develop the market-driven menus and services to meet their needs and expectations.

  • The survey of the 856 students of the dental hygiene departments in 6 universities in Gyunggi, Kangwon, Chungnam, Gyungbuk, and Gyungnam region was carried out. The purpose of the survey is to find their satisfaction measurement with the department and how they recognize the dental hygienist as well as why they selected the dental hygiene department when they applied for university. The result, analyzed by SPSS 15.0, statistically shows that the measurement of satisfaction by each academic year represents the meaningful difference (P<0.05) in all variables such as the "satisfaction with people", "satisfcation with lectures", "satisfaction with facilities", "satisfaction with activities", and "satisfaction with the department characteristic". The measurement of satisfaction by the decision-making factor for the department selection shows the meaningful difference (P<0.05) in the variables of "satisfaction with lectures", "satisfaction with activities", and "satisfaction with the department characteristic". In the case of the measurement of satisfaction with counselling by each academic year, the 3rd year student shows the highest in the career counselling. All the groups recognize for this question as "higher" or "yes", while the higher academic year students were gradually less satisfied. In the case of the level of recognition by each academic year, the 1st year student shows high in the variables of "practical work recognition" and "vocation recognition" and the difference among groups shows statistically meaningful difference(P<0.05).
