  • This study investigated the anti-inflammatory effects of Xanthoceras sorbifolia of seeds oil on RAW264.7 macrophages and TPA (12-O-tetra decanoylphorbol-acetate)-induced ear edema mice. MTT assay method to measure cytotoxicity was formed in RAW264.7 cell. The anti-inflammatory effect was measured by ability to inhibit production nitric oxide (NO) in RAW264.7 cell. Hexane and eight-percent methanol fractions from Xanthoceras sorbifolia seeds oil did not show cytotoxicity. Hexane and eight-percent methanol fractions were showed significantly inhibitory effect on NO production. TPA-induced acute edema was developed in the mouse ears, and Xanthoceras sorbifolia seeds oil dissolved in acetone was applied to inflamed ears. It was found out that Xanthoceras sorbifolia seeds oil could significantly reduce th ear swelling, compared to the control. Overall results indicate that the Xanthoceras sorbifolia seeds oil has anti-inflammatory activity and could be used as a resource of anti-inflammatory materials.

  • 330 Samples of the slaughtered cattle heart muscle were collected from the abattoirs of five regions in Kangwon - do to reveal the frequency of sarcocystis infections during January through December in 1991. The samples were inspected for bradyzoites by the trypsin digestion technique and the possitive samples were fed to dogs and cats for the detection of sporocysts shed in the feces. The results obtained were summarized as follows : 1. The infection rate of bovine Sarcocystis investigated from 330 samples was 43.6%. 2. It revealed that the infection rate of Sarrocystis increased gradully with the advance in the age, 14.5% in below two years, 26.1% in the three years, 30% in four years, 54.7% in five years, 74.4% in six years, 90% in seven years and 100% in older than eight years. 3. The cyst walls detected out from the heart muscles were less than l${\mu}{\textrm}{m}$ in thickness and the size of bradyzoites were $11.8{\times}2.8{\mu}m$ in average. 4. The size of sporocysts shed in the feces of dogs were $15.8{\times}9.8{\mu}m$ in average and the prepatent periods ranged from 12 to 16days. 5. Sarcorystis found in the bovine heart muscles were identified as Sascocystis cruzi ( Hasselman, 1923) , wenyon, 1926.

  • Purpose: The purpose of this study is to examine decision factors to start orthodontic treatment with male and female undergraduates having experience in orthodontic treatment at a dental clinic or hospital because of malocclusion. Methods: A survey was carried out to investigate decision factors to begin orthodontic treatment with 330 male and female undergraduates attending universities located in Daegu Metropolitan City or Gyeongsangbuk-do who had experience in orthodontic treatment at a dental clinic or hospital because of malocclusion, and out of 330 questionnaire sheets, total 294 (89.1%) sheets were employed for analysis after excluding ones unreliably or erroneously answered. Results: According to the results of analyzing decision factors for orthodontic treatment, such factors as 'a dentistry-related person's suggestion', 'feeling necessity on one's own' are found to be significantly higher in students majoring in health units than those having non-dental health majors, and students residing in small and medium cities are influenced more significantly by this decision factor, 'an acquaintance's suggestion', than those living in farming and fishing villages or big cities, and students who started orthodontic treatment at elementary school were more significantly influenced by the factor, 'feeling necessity through the public media'. Conclusion: Among the factors influencing their decision on orthodontic treatment, no influence was found in sexual difference, and each of the decision factors influenced them considerably according to the difference of their residence, economic power, majors, or time to start orthodontic treatment.

  • FCEV uses 250 ~ 450 V instead of using 12 V battery. High voltage vehicle can cause electric shock, fire and explosion accident. Therefore, it has potential factors that can cause hazard of safety for users. United states of America and Europe legislate regulations such as ECE R100, FMVSS 305 for regulating electrical safety during driving or after collision. The company manufacturing high voltage components must do advanced R&D about Method for improving and confirming the safety of high voltage. We develop the specific hardware components of high voltage wiring system for the power train system and power supply system of Hyundai Motors FCEV. This paper shows test method of insulative performance for securing the electrical safety of high voltage components such as power cable, connectors and buss-bar, and proposals the guide line value for human safety of FCEV according to the test result of our development components.

  • 본 연구는 지각된 스트레스가 불면증에 어떠한 영향을 미치는지, 지각된 스트레스가 불면증에 영향을 미치는 과정에서 자기자비와 감사가 매개하는지 알아보고자 하였다. 이를 위하여 경상도와 전라도에 소재한 4년제 대학교에서 대학생 330명에게 지각된 스트레스, 불면증, 자기자비, 감사에 관한 설문을 실시하여 분석하였다. 이중매개효과를 검증하기 위해 기술통계 및 상관분석, SPSS Macro 부트스트래핑(bootstrapping) 방법을 적용하였다. 연구결과, 첫째, 지각된 스트레스가 높을수록 불면증이 높았다. 둘째, 지각된 스트레스와 불면증의 관계에서 자기자비 및 감사가 각각 부분매개하였다. 셋째, 지각된 스트레스는 자기자비와 감사의 이중매개 경로를 거쳐 불면증에 영향을 미쳤다. 이러한 결과를 중심으로 대학생의 불면증을 예방하고 완화하기 위해서는 스트레스 관리가 중요하며, 더불어 자기자비와 감사를 증진시킬 수 있는 개입이 필요함을 논의하였다.

  • 본 연구는 건조 연근을 포장방법(PE 필름, PP 필름, 마대, 종이봉투)과 저장온도(-5, 0, 10, $20^{\circ}C$)를 달리하여 품질의 변화를 알아보기 위해서 수분함량, 경도변화, 색도를 조사하였다. 저장기간 동안 수분의 함량은 PE, PP 포장재에서 종이봉투 및 마대 처리구 보다 수분함량이 높았으며, 저장온도가 낮을수록 수분함량이 낮게 나타났다. 한편, 마대와 종이봉투 포장재는 온도에 따 시료간의 수분함량 차이에 있어서 PE와 PP의 포장재와 달리 큰 차이를 나타냈다. 색상은 $-5^{\circ}C$에 저장한 마대 및 종이봉투는 저장 330일까지 h값이 안정적인 경향을 나타내었으나 0, $10^{\circ}C$, $20^{\circ}C$에서 저장한 마대, 종이봉투 포장재는 안정적이지 못한 경향을 나타냈다. 경도는 온도에 의해 약간 차이가 나지만 PE와 PP포장재가 다른 포장재보다 경도 값이 높았으며 또한 부패현상, 갈변반응 억제도 효과적인 결과를 나타냈다.
