Over the past two decades suicide terrorism has become an ever-widening phenomenon. When suicide terrorism was first introduced in the Middle East it seemed that this new phenomenon was invincible and that it might change the innate imbalance between terror groups and their rivalry governments. This did not in fact occur. Looking at history of terrorism, it can be seen that suicide attacks are in actuality a very old modus operandi. However, contemporary suicide terrorism differs from such historical tactics, just as the whole phenomenon of terrorism differs from ancient modes of warfare. Modern suicide terrorism is aimed at causing devastating physical damage. through which it inflicts profound fear and anxiety. Its goal is to produce a negative psychological effect on an entire population rather than just the victims of the actual attack. The relatively high number of casualties guaranteed in such attacks, which are usually carried out in crowded areas, ensures full media coverage. Thus, suicide terrorism, ranks with other spectacular modus operandi such as blowing up airplanes in mid air or the use of Weapons of Mass Destruction as a sure means to win maximum effect. For the purposes of this paper a suicide terror attack is defined as a politically motivated violent attack perpetrated by a self-aware individual (or individuals) who actively and purposely causes his own death through blowing himself up along with his chosen target. The perpetrator's ensured death is a precondition for the success of his mission. The greatest potential risk suicide terrorism may pose in future is if terrorists carry out operations combined with other spectacular tactics such as blowing up airplanes or the use of Weapons of Mass Destruction. Such a combination will increase immensely the death toll of a single terror attack and will have a shocking psychological effect on public moral. At this level suicide terrorism would constitute a genuine strategic threat and would probably be confronted as such. This study portrays a general overview of the modern history of suicide terror activity worldwide, focusing on its main characteristics and the various aims and motivations of the terror groups involved. In addition, This study provides an overview what is to be done to prevent such terrorist attacks.

본 연구에서는 업무스트레스 관리를 위해 호흡과 심장박동간의 상관관계를 이용한 최적 호흡법을 유도하고 반복 훈련을 통해 사용자의 건강을 자가 관리하는 시스템을 개발하였다. 일정한 호흡은 심장의 항상성을 유지할 수 있도록 도움을 준다. 심장의 항상성 유지를 통해 업무스트레스 자극으로 인한 심장 리듬의 변화를 빠르게 안정시킬 수 있다. 사람은 개인에 맞는 고유한 호흡리듬을 가지고 있기 때문에, 최적 호흡리듬을 반복적으로 훈련하는 것을 통해 심장의 항상성을 높일 수 있다. 본 시스템은 개인에 맞는 최적 호흡리듬을 찾아서 이를 반복적으로 훈련할 수 있는 시스템을 개발하였다. 그리고 업무스트레스가 높은 콜센터 직원들을 대상으로 검증실험을 실시하였다. 검증실험 결과 자신의 맞는 호흡주기를 사용하여 호흡을 하면 심장의 반응이 안정성을 보이고 부교감이 활성화 되는 것을 확인할 있었다. 개발한 시스템을 활용하면 감정노동자들 중에서 콜센터 상담 업무스트레스를 저감시킬 수 있을 뿐만 아니라, 이를 통한 업무효율증가와 개인의 건강관리에도 많은 도움을 줄 수 있을 것으로 예상된다.

Neural stem cells (NSCs), with self-renewal and neuronal differentiation capacity, are a feasible resource in cell-based therapies for various neurodegenerative diseases and neural tissue injuries. In this study, we investigated the effects of Schisandrae Fructus (SF) on proliferation and differentiation of human embryonic NSCs. Treatment with 70% ethanol extract of SF increased the viability of NSCs derived from human embryonic stem cells, which was accompanied by increased mRNA expression of cyclin D1. Whereas 70% ethanol extract of SF also decreased the mRNA expression of nestin, it increased class III ${\beta}$-tublin (Tuj-1) and MAP2 in both growth and differentiation media. Lastly, we found increased mRNA expression of BDNF in SF-treated NSCs. In conclusion, our study demonstrates for the first time that SF induced proliferation and neuronal differentiation of NSCs and increased mRNA expression of BDNF, suggesting its potential as a regulator of NSC fate in NSC-based therapy for neuronal injuries from various diseases.

AIDS is increasing by geometric progression in the world with more seriousness and HIV/AIDS is still spreading. Thus, the study enforced a self-administered survey with 526 dental hygiennics students to carry out an upright recognition and education on AIDS by grasping knowledge and attitude of dental hygienics students who will work at dental hospitals or clinics after graduating in AIDS. As the result, the study got the following conclusion. 1. 51.1% of the students got knowledge on AIDS and the majority out of them got its knowledge through school(35.2%) or mass media(10.8%). 2. The average score of dental hygienics students' knowledge in AIDS was 87.67: The first-grade students(86.00), the second-grade students(88.88) and the third-grade students(88.37) (p=0.000). 3. They had an accurate recognition about AIDS' causes, its infection ways and interceptive methods of its infection way in knowledge of AIDS(p=0.000). 4. In their attitudes for AIDS, the average score was $57.43{\pm}$: The first-grade students(56.19), the second-grade students(57.70) and the third-grade students(58.70)(p=0.001). 5. In their attitudes for AIDS, the students($4.09{\pm}0.82$ scores) responded that they would prepare for AIDS' infection of their families(p=0.004) while, on the other hand, the students($4.06{\pm}0.82$ scores) responded that they wanted to avoid PWA's dental treatment(p=0.001). Therefore, it is judged that vocational education as a specialized worker as well as AIDS education should be realized since it was appeared that they had not enough thought as a mature professional worker. 6. Dental hygienics students who would work at dental hospitals or clinics after graduating were in the environment infected in all diseases and so most of the students($4.23{\pm}0.74$) responded that AIDS education should be included in curriculum.

언론행위는 사회적 실천행위다. 따라서 무엇이 옳고 그런가에 대한 판단이 전제되어야 한다. 언론에 철학이 필요한 이유다. 언론철학의 빈곤은 언론의 도구화를 촉진한다. 어떤 권력이나 자본도 언론의 본질적인 철학을 침범하도록 해서는 안 된다. 언론은 언론의 본질적 가치를 지켜야 한다. 언론의 본질적 가치를 침해당했음에도 불구하고 침묵하는 것은 언론 스스로 존재가치를 부정하는 것이다. 즉 자기 배반이다. 언론의 사회적 실천은 언론의 본질적 가치를 지키고 실현하는 과정이다. 따라서 역사적이다. 언론이 역사와 만나는 지점이다. 역사의식 없는 언론은 곧 철학의 빈곤이다. 철학 없는 언론은 역사적 소명의식을 가질 수 없다. 언론철학은 역사를 통해서 현실로서 들어난다. 역사적 현실을 통해 언론철학의 구체성은 들어난다. 언론철학과 언론역사 연구 간의 대화가 필요한 이유다. 따라서 본 연구는 언론철학이 언론역사 속에서 어떻게 형성되고 재구성되는지 살펴본다. 동시에 언론역사 속에서 언론철학은 어떻게 구체화 되는지, 역사적 주체들이 어떻게 언론을 실천하는지, 그것의 언론사적 의미가 무엇인지를 탐구한다.

This study was carried out to investigate the lactation and weaning practice of infants and their mothers' attitude on infant nutrition. We interviewed 152 mothers in three pediatric clinics located in Sokcho city. From this survey, $76.3\%$ of infants was fed colostrum milk during first one week of life. During the first 4 months, $31.6\%$ of infants was fed breast-milk, while $42.8\%$ of them was fed bottled-milk. More housewives fed their babies with breast milk than the working mothers. Infants ate first weaning food at 5.73$\pm$1.86 months of life. Highly educated mothers showed positive response to the questionnaire : Breast-feeding is good for baby but it requires mother's sacrifice, and Breast-feeding may ruin the good shape of mothers. Highly income mothers responded negatively to the statement : Breast-feeding is not a must for infants since bottled-milk is a good substitution for breast-milk. Comparing with the mothers whose income was about 1 -2 million won per month, with ones who got paid less than 1 million won per month the former responded positively to : Breast-feeding is good for baby but it requires mother's sacrifice. Mothers recognized the importance of weaning in the following order : Supply of nutrition, Enforcement of digestion and absorption capability, Variety of taste, Disease prevention, Development of self-reliance, and Development of baby tooth. To improve the infants' nutritional status, education program on infant nutrition should be organized and run for the pregnant and lactating women in obstetrician and pediatric clinics and through the mass media as well.
