  • Recently many different programming languages have emerged for the development of bioinformatics applications. In addition to the traditional languages, languages from open source projects such as BioPerl, BioPython, and BioJava have become popular because they provide special tools for biological data processing and are easy to use. However, it is not well-studied which of these programming languages will be most suitable for a given bioinformatics task and which factors should be considered in choosing a language for a project. Like many other application projects, bioinformatics projects also require various types of tasks. Accordingly, it will be a challenge to characterize all the aspects of a project in order to choose a language. However, most projects require some common and primitive tasks such as file I/O, text processing, and basic computation for counting, translation, statistics, etc. This paper presents the benchmarking results of six popular languages, Perl, BioPerl, Python, BioPython, Java, and BioJava, for several common and simple bioinformatics tasks. The experimental results of each language are compared through quantitative evaluation metrics such as execution time, memory usage, and size of the source code. Other qualitative factors, including writeability, readability, portability, scalability, and maintainability, that affect the success of a project are also discussed. The results of this research can be useful for developers in choosing an appropriate language for the development of bioinformatics applications.

  • Edwardsiella tarda, the causative organism of Edwardsiellosis, was isolated from the water and the eel, Anguilla japonica of the recirculating eel culture ponds in 1988. E. tarda was always isolated from the water of eel culture ponds in the number of log 2.30~log 4.78 CFU/$m{\ell}$ without distinguishable seasonal characteristics. The counts of isolated E. tarda were changed with the health condition of the eel, i. e., a number of E. tarda were isolated from all checked organs, intestine contents, liver, spleen and kidney of the diseased eel, however, it was hardly isolated from spleen and kidney of the healthy eel. The isolates were classified according to o-agglutinating test into three serotypes (I, II, III). There were no distinct differences in the composition of the serotypes between intestine contents of eel and pond water samples(I, 52.4~53.3% ; II, 20.0~23.8% ; III, 4.8~6.7%). Serotype I was ascendant in the spleen(66.7%) and the kidney(73.7%) samples. By experimental challenge, most of serotype I proved highly virulent to eel in comparison with the other serotypes tested.

  • The aim of this paper is to discuss how designers lead and direct 'technology-driven society' using their creative communication skill. To this end, it is required for communication designers to take conscious steps to recognize the future direction of their profession. Despite the advancement in technology, there is a human being at the center of all design activities. From a certain point of view, contemporary communication design takes an open-ended exploration of the subject matter, rather than a finished output. The notion of creative leadership may potentially expand more in terms of improving the methodology of today's visual culture. The paper will examine creative leadership that could be proposed by the challenge of discourse upon the upcoming industrial revolution. Today, communication designers are confronted by new leadership opportunities and challenges. Some leading designers seem to focus on brand new media technologies to prepare the 4th industrial revolutions. However, communication design cannot be discussed in the medium but can be understood as a process. Top-down and bottom-up process is always a concerned about the relationship since the focus of leadership has changed. In the top-down process, the leadership has existed between 'designer and client' because designers have played their role as a problem solver. On the other hand, there is a different model of leadership between 'design and technology' based on bottom-up process, which stem from the design authorship. In this regard, the new definition of creative leadership in the $4^{th}$ industrial revolution proposes a designer as a problem-finder based on the relationship between the 'designer and the public'.

  • A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.

  • This pilot study examined the contribution of citizen science approach to the datification of factors influencing the progress of cognitive health of the older adults. Newspapers were reviewed and FGIs of field workers at a Day Care Center gathered relevant data from citizen. Two questions were put forward; whether new factors are drawn from citizen knowledge; if yes, whether they represent a new type of data. 'Aesal', personality of the older adults with dementia is noted as a new dementia affecting factor. The data on personality also present a new challenge for scientific measurement. The relationship between personality or psychology of the older adults and the risk of getting dementia has been a research field for a long time, yet the impact of personality on the progress of dementia has not been examined scientifically. Because of communication difficulties with the older adults with dementia, new types of indicators and new ways of measurements thus need to be developed.

  • With the acceleration of urbanization and industrialization, air pollution has become increasingly serious, and the pollution control situation is not optimistic. Climate change has become a major global challenge faced by mankind. To actively respond to climate change, China has proposed carbon peak and carbon neutral goals. However, atmospheric pollutants and meteorological factors that affect air quality are complex and changeable, and the complex relationship and correlation between them must be further clarified. This paper uses China's 2013-2018 high-resolution air pollution reanalysis open data set, as well as statistical methods of the Pearson Correlation Coefficient (PCC) to calculate and visualize the design and analysis of environmental monitoring big data, which is intuitive and it quickly demonstrated the correlation between pollutants and meteorological factors in the temporal and spatial sequence, and provided convenience for environmental management departments to use air quality routine monitoring data to enable dynamic decision-making, and promote global climate governance. The experimental results show that, apart from ozone, which is negatively correlated, the other pollutants are positively correlated; meteorological factors have a greater impact on pollutants, temperature and pollutants are negatively correlated, air pressure is positively correlated, and the correlation between humidity is insignificant. The wind speed has a significant negative correlation with the six pollutants, which has a greater impact on the diffusion of pollutants.

  • The purpose of this study was to analyze the contents related to health in the three major monthly women's magazine that was printed from March, 1997 to February, 1998. The unit of analysis was the section of health, living life, and reaing child. The total number of related story of health was 317. The analysis was done according to the target, health management, topics and the informer by using frequency and number. The findings are as follows : 1. The contents were categorized by target people. The number of items for women was 113(35.6%), child(17.4%), family(15.5), husband(4.7%) and others(26.8%). Others were the contents that are impossible to classify. 2. The number of items of contents by health management was the related to health maintenance and promotion 120(47.8%), health care when they were deviated from health 26(10.3%), and those of both attributes 105(41.8%). 3. The number of items of contents by topics was the related to the occurrence, prevention and treatment of various kinds of disease 41(12..9%), diet 37(11.7%), academic information 11.3%, women's disease 10.4%, the effect of foods 6.0%, child's growth & development and child care 5.75, various kinds of therapy for health care 5.7%, sexual life 5.4% and exercise 4.7%. 4. The number of items of contents by informer was medical doctor 215(49%), lay person's case report or report of a struggle against a disease 12.3%, relevant organization of a related story(eg. family therapy research institute, physical therapist's or teacher's) 11.2%, and the contents of existing books or lecture 8.9%. Among those contents, only the one case from nurse or Korean nurses association as informer was founded, which is related to "skinship child care." In conclusion, this finding showed that women's magazine took a role as a important resource providing informations of health to women. it provides a challenge to the health professionals to have concerns on women's needs, and the content, source, and accuracy of the health related information and take part in the process producing information through such as screening and examining so as to give accurate information to women. Then women's magazine can take a role as a major resource for maintaining and promoting women's health. Finally, nurses's, who are professional health care providers, important and active role as informers toward the lay persons, especially for the women who are non-professional care givers at the family unit should be stressed. More active and continual monitoring and analyzing the contents related health in the mass media including magazine and Internet network in detail, and participating in establishing the system of adequate and precise information for women and lay persons from the nursing profession are required absolutely.

  • Reconstruction of the maxilla is quite a difficult challenge for reconstructive surgeons. The maxilla is the most important part of the midface, which contributes to facial esthetics, mastication, swallowing, speech, supporting orbital contents and sinus function. Free fibular flap is most versatile to reconstruct jaw bone because of its adequate length, containing both soft and bony tissues and acceptance of dental implants. In this case report, a reconstruction of the maxilla using free fibular flap and dental implants is described in which rapid prototype was used before surgery to simulate the final prosthetic results.
