Purpose: The purpose of this study was to evaluate the quality of service and appropriateness of information provided in gastric cancer web sites. Method: The study investigated the status of the web sites retrieved when the keyword "gastric cancer" was searched on seven(7) different Internet portal sites. Among the retrieved information sites, 51 domestic websites, available on June and July 2008, were selected. They were evaluated based on two criteria, quality of service (7 items) and appropriateness of the information (11 items) on a 4-point scale($0{\sim}3$). The analysis of data was done using SPSS 12.0 PC+ program for descriptive statistics and ANOVA tests. Results: Findings revealed that the quality of service provided by the web sites had an average of $1.61{\pm}.55$. The score of information appropriateness was $.79{\pm}.64$. Among the studied websites, only 4(7.8%) scored higher than 22, placing them in the top 30%. Conclusion: This study suggests that most sites do not provide diverse types of gastric cancer-related information and that reliability is important in developing web-based programs related to gastric cancer in order to effectively promote and disseminate health information to the general public.

Web sites on the internet are excellent information resources for the consumers to gain health care knowledge. Especially web sites related to child-care more increase recently. But a concern has emerged for the quality of contents contained on the child-care web sites. Lack of evaluation criteria have led to inaccurate and misleading child-care related publications on the Internet. For evaluating the quality and reliability of child-care related information on the Web, rating tool should be provided and developed. So, this article reviewed and investigated the elements to evaluate child-care sites on the internet. On the basis of the review of articles and the validity test about the contents, 16 preliminary items including purpose, contents, authority, feedback, design developed. Through the pilot study that apply the preliminary evaluating criteria to 20 evaluating criteria for child-care web sites developed. This evaluating criteria have 24 items and that were categorized to purpose(2 items), detail of contents(16 items), authority(2 items), feedback(2 items), design(4 items). The result of this study suggest that the evaluation criteria for child-care web sites may be useful for evaluating the quality of child-care web sites.

The market structure and consumer characteristics are changing dynamically according to internet shopping industry developing based on Web 2.0. But, there is absent typical online service after 'Cyworld.' The social shopping sites based on social networking reflect to present phenomenon that collective intellect, information sharing, participate in making information. The social shopping sites are not limited in particular shopping sites but include all of sites in online. So, consumers can copy various products and display on their own blog provided from social shopping sites and make some purchase reviews and any comments about products can lead transactions among social shopping sites. So, it might be a one of meta-shopping mall like 'Naver.' As the social shopping sites are new form, we just applied to TAM theory to figure out acceptance factors using SEM. The perceived enjoyment affect to usefulness, ease of use and using intension. The perceived ease of use also affect to usefulness and the usefulness affect to using intension positively. But the perceived ease of use was for nothing in using intension. Finally, we provided managerial implications to activate domestic online shopping industry and theoritical meaning using extended TAM.

This study is focused upon developing repairing and restoration methodologies of the Paleolithic sites. The Paleolithic era is not only the remote past, which ended ten thounds years ago, but the period of much different ecological condition compared with that of these days. There have been two kinds of conservation method adopted to restoration of Paleolithic sites which are historic park and ecological park. But there left not much historic remains than ecological sources in most Paleolithic sites, restoring them into ecological park is thought to be more reasonable for the purpose of conserving sites and remains. The first step of restoring Paleolithic sites is reconstructing environmental background in which they earned a living with their own life style at that time. There are three ways of ecological restoration for prehistoric sites, which are the reclamation, the rehabilitation, and the restoration. The reclamation requires physical modification, and the rehabilitation does biological modification, but only the restoration requires improved management. Among them, the most desirable way applicable upon the Paleolithic sites restitution is the reclamation.

As the number of harmful sites increases, many social problems are occurring. Therefore, in order to solve this problem, the government is carrying out activities to block access to web sites to harmful sites based on the law. However, due to the change from HTTP to HTTPS protocol, it has become difficult to block the harmful sites in the existing method. In the existing HTTP protocol, a method of blocking the site corresponding to the harmful site domain list by utilizing the DNS information was used. However, due to the generalization of HTTPS, it is difficult to block the harmful sites in the existing method. Therefore, the ISP uses the method of blocking the website using the SNI field in the TLS (Transport Layer Security) Handshake protocol used for HTTPS. However, since the method using SNI field raises the concern of monitoring Internet users or exposing information about connected sites, in this paper, we proposed method which can support anonymity to Internet users while blocking harmful sites. The suggested method also can support integrity and source authentication to the transmitted data.

We investigated the changes in the population size and inter-specific space usage for breeding in mixed breeding sites of the great cormorant (Phalacrocorax carbo), grey heron (Ardea cinerea), great egret (Ardea alba modesta) and intermediate egret (Egretta intermedia) in Gammul-myeon, Goesan-gun, Chungcheongbuk-do, South Korea, in 2016-2017. These species bred in two adjacent habitats (site A and site B). The number of breeding pairs of all species and the size of the breeding area at site B increased in 2017. In 2017, great cormorants at site B occupied the breeding sites previously occupied by the other species in 2016, while the grey heron and great egret occupied the sites around the great cormorant breeding site. The heights of nest trees and nests of great cormorant and grey heron did not differ temporally, but these heights in site B were significantly higher than those in site A for great cormorants. For great egrets, these greatly decreased in site B in 2017. Thus, the great cormorant either moved to favourable nest sites for breeding success or selected nest sites used by the herons in the previous year. Further studies of these two possibilities are necessary.

With the advances in Information Technology (IT), users can download or stream copyrighted works, such as videos, music, and webtoons, at their convenience. Thus, the frequency of use of copyrighted works has increased. Consequently, the number of unauthorized copies and sharing of copyrighted works has also increased. Monitoring is being conducted on sites suspected of conducting copyright infringement activities to reduce copyright holders' damage due to unauthorized sharing of copyrighted works. However, suspected copyright infringement sites respond by changing their domains or blocking access requests. Although research has been conducted for improving the effectiveness of suspected copyright infringement site detection by defining suspected copyright infringement sites' response techniques as a lifecycle step, there is a paucity of studies on automation techniques for lifecycle detection. This has reduced the accuracy of lifecycle step detection on suspected copyright infringement sites, which change domains and lifecycle steps in a short period of time. Thus, in this paper, an automated detection technique for suspected copyright infringement sites is proposed for efficient detection and response to suspected copyright infringement sites. Using our proposed technique, the response to each lifecycle step can be effectively conducted by automatically detecting the lifecycle step.

In proportion to the rapid development of information and communication technology, the damage to copyright infringement is also increasing. In particular, as the OTT platform market has grown significantly in recent years, the speed and distribution of pirated copies that infringe copyright are increasing rapidly compared to the past. Accordingly, the country is trying to prevent copyright infringement by detecting and blocking illegal streaming sites, but it is difficult to expect great results due to the fast production of illegal streaming sites. Therefore, in this paper, we analyze the causes of rapid production of blocked illegal streaming sites, track and analyze 58 illegal streaming sites, and propose ways to effectively block illegal streaming sites based on the analysis results.

Nile perch and Nile tilapia are major commercial species in Uganda, and thus require continuous production. However, their production is impacted by anthropogenic activities such as fishing in breeding habitats. The aim of this study was to identify and characterize Nile perch and Nile tilapia fish breeding habitats on Lake Kyoga. Water quality, lake bottom, fish and vegetation type samples were collected from 20 sites in April of 2021 and 2022. Key informant interviews were conducted with experienced fishermen at five fish landing sites. The water quality parameters indicated significant difference within the sites using analysis of variance. Sandy and muddy bottom types were equally spread at 40% each by use of a pie chart. Fish gonads showed no significant difference among the 20 sites. Bivariate correlation analysis of the vegetation types indicated a strong negative correlation with Nile perch while Nile tilapia had a positive correlation. Principal component analysis of the water quality, fish gonads and habitat vegetation components cumulatively contributed 82.5% in characterizing a fish breeding habitat. Four sites for Nile perch and four sites for Nile tilapia were characterized as breeding sites on Lake Kyoga and are recommended for mapping and gazettement as breeding habitats for sustainable fisheries management.

Among all industries, the construction industry still remains a traditional one with low productivity due to its labor-intensive and field-dependent production system, its supplier-oriented industrial structure, and the disruption of the information flow between participants. In addition, the construction industry in South Korea has recently been required to transform itself according to social trends such as aging, the reduction of skilled workers, and the shortening of working hours, and the disaster and death rates in the industry, which are more than twice as high as those in other industries, are making it more necessary to solve chronic safety problems. Therefore, the purpose of this study is to grasp the actual condition of safety management on construction sites in South Korea and analyze cases of K-smart technology utilization for preventing safety accidents on construction sites. The study investigated and analyzed the following. First, construction sites in South Korea were analyzed by type of safety accident, by type of construction, and by construction contract amount. Second, the current status of accidents on small-sized construction sites with a high fatal accident rate and cases of safety accidents on construction sites were investigated. The results of the study are expected to contribute to the dissemination and spread of smart safety technology for not only identifying major factors in safety accidents that occur on construction sites but also preventing workers from suffering accidents.
