Introduction: Increasing prevalence of human papilloma virus (HPV) infection and its association with cervical cancer as a leading cause of death make it necessary to evaluate and improve the public knowledge, especially of university students, about this cause of disease. Methods: A cross-sectional study of knowledge and attitude of a total 669 students from Tabriz University of Medical Sciences was therefore performed with a modified validated questionnaire, arranged into 5 parts and containing 55 questions, in July 2011. Questions were directed to study socio-demographic characteristics of the participant, knowledge about HPV disease, transmission route, relationship with cervical cancer, predisposing factors, and participants attitude toward people with HPV infection. Results: All of the participants were Moslem with a mean age $25.6{\pm}5.33$ years of age. All of the participants had heard of HPV, and acquired their knowledge through university courses (90.6%); the majority of them knew that HPV is a sexually transmitted disease and a potential cause for genital warts but general knowledge about details was not high. Mean knowledge score of residents and post graduate midwifery and nursing students was high as compared to other groups (P<0.001). Statements that indicated the presence of fear to communicate with people suffering HPV and people's avoidance to rely on babysitting of these patients were observed. Educational level (${\beta}$=0.21, P<0.001), age (${\beta}$=0.18, P=0.002,) and smoking (${\beta}$=-0.11, P=0.006) were predicted to effect knowledge. Conclusions: Moderate level of knowledge about HPV among medical university students makes it necessary to set effective national public health efforts on HPV education and prevention considering he excess of young population in Iran vulnerable to cervical cancer.

The purpose of this study is to survey and analyze the growth, management and surrounding environment of the big and old trees in Kyoungju-si or the cultural assets alive in our history, and thereby, provide for some data useful to their reasonable protection and use of their surrounding areas. As a result of surveying the growth conditions of the big and old trees, it was found that the height of new grass was 10.5cm on average, the activity scale of the wood was 7.2k$\Omega$, the soil hardness was $16.7kg/cm^2$, the soil acidity was pH 4.8, and the soil moisture was $13.3\%$. Such findings suggest that the soil has been acidified by people's frequent passages, but that the other growth conditions are more or less normal. Hence, it is desirable to secure a sufficient space around the trees or reduce people's stamping pressure with some mechanisms. On the other hand, the visible conditions of the trees were found more or less normal, but many trees remained cut or barked (with some cavities), requiring an optimal treatment or measure. Lastly, as the population has decreased in the suburban traditional villages, the surrounding environment seems to be less vulnerable to people's frequent visits. Nevertheless, in consideration of the fact that there are only a few public space for the villagers, it is deemed necessary to rearrange or maintain some parts of the surrounding environment as public space for villagers or hikers.

인터넷에서의 사용자 인증은 안전한 통신을 위해 가장 중요한 서비스 중의 하나이다. 비록 패스워드 기반 메커니즘이 네트워크 상에서의 사용자 인증을 위해 가장 많이 쓰이는 방법이기는 하나, 사용자들이 기억하기 쉬운 패스워드(easy-to-remember)를 사용하므로, 사전공격(dictionary attack)에 취약한 것과 같은 근본적인 문제점들을 가지고 있다. 이러한 사전공격을 방지하기 위만 방법들의 경우에는 높은 계산량을 필요로 한다. 본 논문에서는 이러한 문제를 해결하기 위한 최근에 발표된 OSPA 프로토콜에 대하여 설명하고, OSPA 프로토콜이 stolen-verifier 공격과 impersonation 공격에 취약함을 보인다. 그리고 이러한 공격들에 안전한 개선된 OSPA 프로토콜을 제안한다. 제안하는 프로토콜은 스마트 카드에 탑재된 co-processor를 통해 암호학적 연산이 수행되므로 사용자에게 낮은 계산량을 제공한다.

The problems and needs of families in Hong Kong are becoming more complex. Traditional family structures and functions are rapidly eroding. Moreover, family problems are further exacerbated by a growing number of socio-economic issues including rising divorce rates and extra-marital affairs. continuous family reunion migration from Mainland China, emotional and financial cost of caring for the older people and the changing economy which has pushed more families into hardship. In effect, more and more families are becoming vulnerable to risk. Traditional family services in Hong Kong are varied in mode, operation and provision, often overlapping in service boundaries with other family-oriented programs. In many instances, family service centers are stretched far beyond their capacity. As a consequence, they become too reactive, remedial and casework dominated. The University of Hong Kong Consultant Team recommended that family service programs have to protect vulnerable families and strengthen family capacities to promote maximum independence. The direction of family services is summarized as: strengthening families; child-centered, family-focused and community-based. New integrative family service centers aim at attaining the principles of promoting accessibility to users with minimum physical, psychological and administrative barriers; early identification of needs and intervention before the further deterioration of problems; integration of services cutting across program boundaries, and partnership between service providers to achieve efficient and effective use of scarce resources. Under the new model, multi-skilled teams can respond more proactively to a wide range of social needs, rather than addressing needs in isolation. To demonstrate the effectiveness of the new model, the consultant team has been commissioned by the government to evaluate the performance of these two-year pilot projects. More importantly, a coherent and family-friendly social policy should be formulated to strengthen family capacity against family-related problems.

Background: The "Tuberculosis Relief Belt Supporting Project (Tuberculosis Patient Management Project for Poverty Groups)" is a national program for socioeconomically vulnerable tuberculosis (TB) patients. We sought to evaluate the clinical and socioeconomic characteristics of poverty-stricken TB patients, and determined the need for relief. Methods: We examined in-patients with TB, who were supported by this project at the National Medical Center from 2014 to 2015. We retrospectively investigated the patients' socioeconomic status, clinical characteristics, and project expenditures. Results: Fifty-eight patients were enrolled. Among 55 patients with known income status, 24 (43.6%) had no income. Most patients (80%) lived alone. A total of 48 patients (82.8%) had more than one underlying disease. More than half of the enrolled patients (30 patients, 51.7%) had smear-positive TB. Cavitary disease was found in 38 patients (65.5%). Among the 38 patients with known resistance status, 19 (50%) had drug-resistant TB. In terms of disease severity, 96.6% of the cases had moderate-to-severe disease. A total of 14 patients (26.4%) died during treatment. Nursing expenses were supported for 12 patients (20.7%), with patient transportation costs reimbursed for 35 patients (60%). In terms of treatment expenses for 31 people (53.4%), 93.5% of them were supported by uninsured benefits. Conclusion: Underlying disease, infectivity, drug resistance, severity, and death occurred frequently in socioeconomically vulnerable patients with TB. Many uninsured treatment costs were not supported by the current government TB programs, and the "Tuberculosis Relief Belt Supporting Project" compensated for these limitations.

Objectives : This study presents a scientific basis for the establishment of an environmental health contingency plan for dealing with accidental coastal oil spills and suggests some strategies for use in an environmental health emergency. Methods : We reviewed the existing literature, and analyzed the various fundamental factors involved in response strategies for oil spill. Our analysis included data derived from Hebei Spirit oil spill and used air dispersion modeling. Results : Spill amounts of more than 1,000 kl can affect the health of residents along the coast, especially those who belong to vulnerable groups. Almost 30% of South Korean population lives in the vicinity of the coast. The area that is at the highest risk for a spill and that has the greatest number of people at risk is the stretch of coastline from Busan to Tongyeong. The most prevalent types of oil spilt in Korean waters have been crude oil and bunker-C oil, both of which have relatively high specific gravity and contain volatile organic compounds, polycyclic aromatic hydrocarbons, and metals. In the case of a spill of more than 1,000 kl, it may be necessary to evacuate vulnerable and sensitive groups. Conclusions : The government should establish environmental health planning that considers the spill amount, the types of oil, and the distance between the spot of the accident and the coast, and should assemble a response team that includes environmental health specialists to prepare for the future oil spill.

Connection hijacking은 TCP 스트림을 자신의 머신을 거치게 리다이렉션 할 수 있는 TCP 프로토콜의 취약성을 이용한 적극적 공격 (Active Attack)이다. 리다이렉션을 통해 침입자는 SKEY와 같은 일회용 패스워드나 Kerberos와 같은 티켓 기반 인증 시스템에 의해 제공되는 보호 메커니즘을 우회할 수 있다. TCP 접속은 누군가 접속로 상에 TCP 패킷 스니퍼나 패킷 생성기를 가지고 있다면 대단히 취약하다. 스니퍼의 공격으로부터 방어하기 위하여 일회용 패스워드나 토큰 기반 인증과 같은 사용자 식별 스킴이 사용되어지고 있다. 이들은 안전하지 않은 네트워크상에서 스니핑으로부터 패스워드를 보호하지만 이러한 방법들은 데이터 스트림을 암호화하거나 사인하지 않는 한 적극적인 공격으로부터 여전히 취약하다. 많은 사람들이 적극적 공격은 대단히 어렵고 그만큼 위협도 적을 것이라고 생각하고 있지만 여기서는 이러한 환상을 깰 수 있도록 유닉스 호스트에 성공적으로 침입한 대단히 적극적 공격을 제시한다. 최근 이론적으로 알려진 이 취약점을 공격할 수 있는 도구가 인터넷 상에 공개되어 이에 대한 대책이 요구되고 있다. 본 논문에서는 무선네트워크 상에서 침입자탐지 분석기법에 대하여 제안한다.
