This study was conducted to investigate the oral health perception according to the actual condition of oral hygiene products management in 222 college students in Daegu and Kyungbuk province (p<0.05). The subjects in the study were 43 men (19.4%) and 50 women (22.5%) with two toothbrushes (p<0.05), and the major subjects were 2 tooth brushes The subjects were 18 (8.1%) and 75 subjects (33.8%) were subjects of science major (p<0.001). Among the subjects who did not carry a toothbrush, 72(32.4%) were male and 46 (20.7%) were female. The number of subjects who did not carry the male was higher (p<0.05) The subjects were as follows: 83 (37.4%), and 21. Oral health awareness was 3.031 times higher than that of male (p<0.001), and the major group was 2.57 times higher than that of the general population (p<0.001). Subjects who did not sterilize the toothbrush had 0.459 times lower oral health perception (p<0.05). In order to establish and evaluate the oral health policy of university students in Korea, only the objective oral health status is used as an index. However, it is necessary to study and reflect the variables affecting oral health awareness as much as the oral health awareness reflects not only oral health condition but also socioeconomic variables and the effect of variables on oral health.

Many patients with dizziness present with a symptom pattern that does not reveal the cause by neurotologic diagnostic approaches. In such cases, the physician frequently diagnoses psychogenic dizziness. Psychogenic dizziness is not characterized by true vertigo, and occurs in combination with other psychiatric symptom cluster. One out of two to four patients with dizziness are psychogenic dizziness. But there are few concern about this including clinical practice and study in Korea. I wrote this paper to increase concerning and attending to this for psychiatrists in Korea. I reviewed etiology including biological and psychological relations between dizziness and psychiatric disorder(especially anxiety), diagnostic approaches of, characteristics of dizziness of various psychiatric disorders related to, and the treatment of psychogenic dizziness. I also briefly reviewed the central and peripheral dizziness for psychiatrists. I suggest psychiatrists and clinicians in the psychosomatic field in Korea to acknowledge, concern, and attend to psychogenic dizziness. In turn, it will be helpful to well treat the patients with psychogenic dizziness.

This work aims to propose a vulnerability assessment methodology of ecosystem at present time, and an to suggest an adaptation strategy of ecosystem in the future for local government, in the fields of plant, animal and conservation area, which would occurred due to climate change. Vulnerability assessment in ecosystem includes first, tree growth and distribution part, mainly for conifers, secondly, insect part for pest and bee, and thirdly conservation area management part, especially at the national parks. To evaluate the degree of vulnerability of each substitute variables, such as exposure of climatic element, sensitivity, and adaptation ability, are respectively selected. Vulnerabilities of conifer growth and distribution, pest and bee, and national park management seem to be strongly influenced by the exposure of climatic element than other factors, such as sensitivity and adaptation ability. With time regional gaps of ecosystem vulnerability are expected to be greater in both conifers growth and distribution, and national park management, but reduced in pest and bee in 2100 in comparison with present time.

Pharmaceuticals and personal care products (PPCPs) are emerging contaminants in aquatic environmental samples. Therefore, it required rapidly and certainly analytical method for pharmaceuticals which are existed in environment. In this study, Liquid chromatography/tandem mass spectrometry (LC-MS/MS) with electrospray ionization (ESI) was used to measure the concentrations of 7 pharmaceuticals (quinoxaline-2-carboxylic acid, acetylsalicylic acid, diclofenac-Na, naproxen, ibuprofen, mefenamic acid, talniflumate) from environmental water or aquatic samples simultaneously. Effective sample clean-up by solid-phase extraction (SPE) prior to LC-MS/MS analysis is necessary. For further purification, Mixed Cation eXchange (MCX) and Hydrophilic-Lipophilic Balance (HLB) solid-phase extraction (SPE) cartridges were used to eliminate the remaining interferences. LODs (Limits of Detection) and MDLs (Method Detection Limits) for the spiked sample in fresh water were in the range of 0.05~1.50 pg/mL and 0.17~4.90 pg/mL, respectively. The absolute recovery in the concentration of 1.0 ng/mL were between 81.9 and 116.3%. The acidic pharmaceuticals were detected in concentrations of 0.018~16.925 ng/mL in aquatic environmental samples.

고3때 인문계에서 자연계로 대입 진학계열을 바꾼 이후 수학을 혼자 공부하면서 수학에 흥미를 갖게 되었다는 건국대 금종해교수는 수학분야중 비교적 역사가 짧은 대수기하학분야 신진학자들의 리더 역할을 하는 주목받는 수학자이다. 금교수는 K3곡면의 대창성에 관한 연구를 집중적으로 연구하고 있는데 97년에는 K3곡면의 일종인 Kummer 곡면의 대칭군에 관한 연구를 권위있는 해외학술지에 발표하여 관심으로 모으기도 했다.

우주공간의 기계, 기구에 있어서는 무게에 기인하는 운동의 저항이 없기 때문에 마찰저항의 제어가 결정적으로 중요하게 된다. 이과제에 대하여 저자들은 여태까지의 고체윤활법와는 다른 새로운 Tribo-Coating 법을 개발하여 그 유효성을 나타내어 왔다. 본 연구에서는 피막재로서 전회의 보고에서 이미 유효성이 나타난 바 있는 In을 사용하여 마찰반복수에 다른 마찰계수변화에 미치는 Pin, disc의 표면거칠기의 변화의 영햐응 명확하게 밝히고, 초고진공중에 있어서 Tribo-Coating법에 의한 In 막의 윤활기구를 검토하고저 한다.

현재 소프트웨어 개발에서 증가적으로 채택되고 있는 컴포넌트 기반 소프트웨어 엔지니어링(CBSE)에서, 새로운 프레임 ？에서의 컴포넌트의 효율적인 동작을 위한 컴포넌트 변형이나, 컴포넌트 통합은 활발히 연구가 진행중이나, 변형이나 통합으로 인하여 발생 할 수 있는 오류들을 테스팅하는 방법이과, 툴은 부족한 현실이다. 본 논문에서는 컴포넌트의 통합, 변경시 발생할수 있는 에러들을 쉽게 검출하기 위하여 본 논문에서 제안한 CCG(Component Calling Graph)를 이용하여 컴포넌트간의 의존성을 추적하고 selection 알고리즘을 거친 테스트 케이스 추출을 통한 컴포넌트의 효율적인 테스팅 방법을 제안하였다.

이 글에서는 21세기에 대비한 창조와 모험의 대학인 멀티미디어 학부의 설립 과정과 패러다임을 통해 대학의 교육개혁 사례를 보이고자 한다. 멀티미디어 학부는 국내.외적으로 아직 학문적 체계화가 이루어지지 않은 '벤처 대학'에 해당한다. 여기서 사례로 제시한 한남대 멀티미디어 학부의 패러다임은 국내.외의 다른 대학에도 영향을 줄 수 있다. 1998년 3월에 설립된 한남대 멀티미디어 학부의 경우, 현재 교육법상 공학사의 자격이 주어지지만, 향후 '멀티미디어 학사'가 주어져야 하며 입학생도 예능계, 문과 및 이과의 학생을 동시에 입학시켜야 할 것이다.
