The openness of the Web allows any user to access almost any type of information easily at any time and anywhere. However, with function of easy access for useful information, internet has dysfunctions of providing users with harmful contents indiscriminately. Some information, such as adult content, is not appropriate for all users, notably children. Additionally for adults, some contents included in abnormal porn sites can do ordinary people's mental health harm. In the meantime, since Internet is a worldwide open network it has a limit to regulate users providing harmful contents through each countrie's national laws or systems. Additionally it is not a desirable way of developing a certain system-specific classification technology for harmful contents, because internet users can contact with them in diverse way, for example, porn sites, harmful spams, or peer-to-peer networks, etc. Therefore, it is being emphasized to research and develop context-based core technologies for classifying harmful contents. In this paper, we propose an efficient text filter for blocking harmful texts of web documents using context-based technologies. 웹의 개방성은 사람들로 하여금 언제, 어디서든 손쉽게 유용한 정보를 획득할 수 있게끔 하였다. 하지만 인터넷은 유용한 정보의 손쉬운 활용이라는 순기능과 더불어 사회적으로 통제를 필요로 하는 유해한 정보 역시 인터넷을 이용하는 이용자들에게 무차별적으로 제공함으로써 역기능을 발생시키고 있다. 성인 컨텐츠 같은 정보들은 모든 사용자들, 특히 청소년들에게 악영향을 미칠 수 있다. 또한, 변태적인 성인 사이트들이 담고 있는 컨텐츠들은 성인들의 정신 건강에도 해를 미치게 된다. 한편, 인터넷은 전 세계적으로 연결된 개방망이므로 유해정보 제공자를 각국의 법적, 제도적 장치를 이용하여 규제하는데 한계가 있다. 또한, 유해 사이트, 유해성 스팸 메일, P2P 등 다양한 경로를 통해 유해 정보를 접할 수 있기 때문에, 어떤 시스템에 특화된 유해정보 분류기술을 개발하는 것은 바람직하지 않다. 따라서, 유해정보의 내용 자체에 기반하여 유해 여부를 자동으로 판별할 수 있는 유해정보 판별 핵심 기술의 연구 및 개발의 중요성이 점차 부각되고 있다. 이에 본 논문에서는 내용 기반 기술을 이용한 효율적인 유해 웹 문서 텍스트 판별 시스템을 제시한다.

The evolutionary structure of a tip vortex in the initial period have been investigated by the two-dimensional LDV system. Circumferential and axial components of mean velocities, their turbulences and Reynolds stresses were measured by the phase averaging technique at seven different wake ages within one revolution of the rotor. Core growth was also analyzed. It was resulted that circumferential velocity components showed a Rankine combined vortex shape and their circulation profiles viewed in the radial direction were close to the n = 2 model of Vatistas' algebraic formula, while axial velocity components seemed to have the Gaussian profiles In these measured ranges with the base width of three times of core radii. Peaks of circumferential velocities and core radii showed distinct asymmetric behaviors before the wake age of $150^{\circ}$ over inboard and outboard sides of the slipstream, but they became symmetric afterwards. Turbulence profiles which had two peaks Inside the core radii in the earlier wake age were also changed to single peaks after $150^{\circ}$. These trends imply that the tip vortex was barely mature at this wake age.

Meckel,s diverticulum is generally acknowledged to be the most prevalent congenital anomaly of the gastrointestinal tract. In the autopsy series, the incidence ranged from 0.5 to 2 percent. The preoperative diagnosis of Meckels divemiculum is difficult, especially in the adult, because of the lesions ability to masquerade as one of a variety of much more common abdominal pathologies. The diagnostic accuracy may be affected by the age of the patient and by complications of diverticulum. The complications that may result include ulcer bleeding, intestinal obstruction, perforation, diverticulitis, stone, and neoplasm. The ways a Meckels diverticulum can cause bowel obstruction are different. Recently we experienced a case of Meckels diverticulitis causing intlammatory reaction and adhesion with the abdominal wall and causing recurrent abdominal pain and obstruction in a 22-year-old woman. Therefore, we present this case with a brief review of the related literature. (Korean J Gastroenterol 1997; 30:826-830)

Purpose : The most common infectious diseases in hemodialysis (HD) patients are sepsis and pneumonia. Although there are many data about sepsis in HD patients, pneumonia in HD patients is rarely reported. This study was conducted to compare clinical severity of pneumonia between HD patients and healthy persons. Methods : This study enrolled 36 HD patients who were admitted for pneumonia. Age- and sex-matched 37 persons with pneumonia who did not have any other medical illness were included as a control. We compared clinical manifestations, laboratory and radiologic findings, complications, and clinical course between HD patients and controls. Results : The positive rates of blood and sputum bacterial culture in the HD patients were higher than in those in the controls (blood; 17.6% vs. 2.7%, p=0.028, sputum; 30.3% vs. 5.4%, p=0.005). Compared to the controls, the HD patients had higher incidence of thrombocytopenia (25.0% vs. 0%, p=0.001) and hypoxia (41.7% vs. 2.7%, p=0.000). The number of the lobes involved was larger and higher incidence of bilateral lesions and parapneumonic effusions were observed in the HD patients. In addition, the HD patients had higher incidence of recurrence than the controls (16.7% vs. 0%, p=0.025). Pneumonia-related mortality rate tended to be higher in the HD patients than the controls but there was no statistical differences between the two groups (11.1% vs. 0%, p=0.054). Conclusion : This study shows that pneumonia in HD patients takes a more severe clinical course than in healthy persons. It seems that pneumonia in HD patients has a higher propensity to develop bacteremia.

This study intended to give helps in planning a specialized exhibition by carrying out a survey objecting to KOREA PACK 2015 attendees including visitors who possessed mobile coupons after finishing advance registration through on-line, and then investigating, analyzing satisfactions of attendees together with effects of the specialized exhibition using IT technology. As a lot of relevant preceeding researches have been made by focussing on exhibition organizer and exhibitors, the viewpoints of attendees at the specialized exhibition using IT conversing technology such as mobile and etc. were to be investigated and analyzed. Thus, this research tried to do an empirical identification on effects of the exhibition by analyzing relations between its watching forms and satisfactions including a survey on the on-line PR route utility of IT technology in addition to visiting motives of attendees who watched the exhibition. A summarization of the current study is followed: First, in case of attending in the exhibition for specific purposes, they searched related information positively, and were shown as doing information gathering behaviors and also high possibility on purchases was confirmed. Second, it was confirmed that positive attendees had decision-making on purchases. This finding means that attendees who watch the specialized exhibition have authority and responsibility of being able to purchase in many cases, so methods of improving sales by effectively doing PR on own products and technical competitiveness in the exhibition are necessary to exhibitors. Third, attendees who have specific purposes showed higher satisfactions on the exhibition than general visitors, but satisfactions on consultation, staff attitudes, and facility were turn out to be higher than providing related information on products or technology. Accordingly, the necessity of improving this outcome was confirmed. Therefore, exhibitors have to endeavor in providing more advanced services to attendees of the exhibition by grasping technical trends in advance as well as cultivating professional staff who can promote products well.

Double prirnary cancer is defined as the case of primary malignant tumors of different site origins, which are different histologically in each other. The absolute number of reported cases of double primary malignant tumors has increased in recent years by means of more developed diagnostic procedure. But the occurrence of multiple primary malignant tumors is relatively rare. We have experienced a case with double primary malignant tumors of different site origins such as gastric lymphoma and duodenal adenocarcinoma, which were diagnosed by biopsies with gastric fiberoptic endoscopy. For its great rarity, we report this case with review of literatures.
