A Web crawler is an important Internet software technology used in a variety of Internet application software which includes search engines. As Internet continues to grow, implementations of high performance web crawlers are urgently demanded. In this paper, we study how to support dynamic scheduling for a multiprocess-based web crawler. For high performance, web crawlers are usually based on multiprocess in their implementations. In these systems, crawl scheduling which manages the allocation of web pages to each process for loading is one of the important issues. In this paper, we identify issues which are important and challenging in the crawl scheduling. To address the issue, we propose a dynamic crawl scheduling framework and subsequently a system architecture for a web crawler with dynamic crawl scheduling support. This paper presents the design of the Web crawler with dynamic scheduling support.

The word P2P implies significant changes in current business dynamics. The P2P service enables individuals to be connected to the Internet for the direct provision of information and even downloads from one another without the conventional method of passing through search engines. This can be utilized to extend the path of retrieving information from limited web sites to personal and enterprise databases. That is, it is now possible for individuals to manage their own information on a national or global scope, share various information with other members, form communities of users interested in sharing homogeneous information, and utilize remote conference and remote education using groupware.

Objectives : The aim of this study is to review the current research trend on the acupuncture and moxibustion treatment for pancreatitis. Methods : Through nine search engines, articles were collected, which had involved the use of acupuncture and moxibustion treatment for pancreatitis. Data were extracted from the selected articles regarding the year, country, type of pancreatitis, study design, evaluation variable, intervention, point for acupuncture and moxibustion, and effectiveness of treatment. Results : Total 56 articles were reviewed. The number of studies increased gradually every ten years. Fifty-one studies(91%) were conducted in China. Most of clinical studies and animal experimentations reported on acute pancreatitis. Thirty-nine studies were randomized controlled trials(RCTs), but most of them were assessed as uncertain in the risk of bias evaluation. The degree of overall improvement(79%) was used mainly as evaluation variable of clinical studies. In animal experimentations, the examination of pancreatitis tissue(77%) and blood test(77%) were used the most. Most of studies were conducted with the acupuncture, one with moxibustion. Among them, electroacupuncture was the most common intervention of treatment group. ST36 was the most frequently used acupuncture point in the included studies. Effective rate increased and serum amylase, clinical symptoms, recovery time of gastrointestinal function decreased statistically significantly in the treatment group of clinical studies. Conclusions : The result of this study could be used for the future practice and research about the acupuncture and moxibustion treatment for pancreatitis.

It's getting popularized to collect information connecting web sites with massive information through the internet and advanced search engines. Users can handle digital materials like E-book wherever the internet is available and they will demand digital information increasingly. This study analyzes literature investigation, statistics analyses of the attached library of Kyushu University, drawings and field investigation to suggest a new model of a library which handles traditional paper-formed materials and digital-formed materials at one place with growing importance of digital materials. It results that a library performs a important role like a learning space and functions as a sociocultural communication space. Also it shows that it is required to basically reinvestigate the role of 'space' in the library with a great importance of digital materials. In the hybrid library combined with subjects and reorganized at one place, One-stop services like library materials and manpower can be provided for users staying at the same area.

Background: Cancer screening rates are lower in Japan than those in western countries. Health professionals publish procancer screening messages on the internet to encourage audiences to undergo cancer screening. However, the information provided is often difficult to read for lay persons. Further, anti-cancer screening activists warn against cancer screening with messages on the Internet. We aimed to assess and compare the readability of pro- and anti-cancer screening online messages in Japan using a measure of readability. Methods: We conducted web searches at the beginning of September 2016 using two major Japanese search engines (Google.jp and Yahoo!.jp). The included websites were classified as "anti", "pro", or "neutral" depending on the claims, and "health professional" or "non-health professional" depending on the writers. Readability was determined using a validated measure of Japanese readability. Statistical analysis was conducted using two-way ANOVA. Results: In the total 159 websites analyzed, anti-cancer screening online messages were generally easier to read than pro-cancer screening online messages, Messages written by health professionals were more difficult to read than those written by non-health professionals. Claim ${\times}$ writer interaction was not significant. Conclusion: When health professionals prepare pro-cancer screening materials for publication online, we recommend they check for readability using readability assessment tools and improve text for easy comprehension when necessary.

Purpose: The purpose of this study was to review sexual abuse prevention education program for Korean elementary school students. Methods: Whittemore and Knafl's integrative review methods were used and Gough's weight of evidence was employed as a quality appraisal tool. Articles published in Korean or English were identified through electronic search engines and scholarly web sites using three keywords: "elementary school student", "sexual abuse", and "prevention education". Peer-reviewed articles published between 2000 and 2018 were included in this review. Results: Twelve articles met the inclusion criteria and were appraised as being high-quality. Among the 12 selected studies, seven were descriptive, while five were intervention studies. Sexual abuse prevention education programs were effective in improving perceptions, knowledge, attitudes, and preventive behaviors among elementary school students. However, deficiencies were found in the variety of educational methods, utilization of experts, and standardization of the content of sexual abuse prevention education. Conclusion: We need to provide various educational methods that are appropriate for specific developmental stages, and the sexual abuse prevention content should draw upon the current sexual education program administered to this population. Furthermore, parents and trained teachers or school health teachers should be included to provide effective education programs for elementary students.

The purpose of this study is to identify trends of academic research on senior employment projects. For this aim, research results were collected from keyword searches utilizing academic search engines, and a total of 133 research studies were selected as analysis subjects. Then, we analyzed research trends such as sources, research themes, research methods, and research subjects using the content analysis method,. According to the results, the leading type of senior employment research was quantitative research that confirmed the effects of projects by targeting the elderly participants. On the other hand, there were relatively few cases in which philosophical and ethical reviews were used to understand the labor and social roles of the elderly in connection with senior employment projects. Based on these research trends, this study criticized the situation where not only a variety of main participants but also the elderly taking part in the senior employment project were excluded from the main concern of research and suggested that it was necessary for follow-up studies to emerge from these trends.
