  • 현대의 많은 광 관련 시스템을 구축하기 위해서는 거시적으로 전체적인 Layout을 대략적으로 결정하는데, 이때 광학계의 구성이 가장 중요한 부분이 된다. 이러한 시스템을 실제 구현하기 위해서는 관련된 광학계의 설계가 요구되며, 이 부분에 많은 기술과 know-how가 요구된다. 또한 참된 설계는 시스템의 제작성과 조립성을 충분히 고려한 설계를 의미하며, 이러한 결과는 철저한 광학계 분석으로부터 얻을 수 있다.

  • 경남 김해시 생림면 생철리 맑은 물과 공기의 친환경속의 조차환 농장은 1980년부터 한우 사육을 시작하여 벌써 30여년이 되었다. 처음에는 실패를 거듭하면서 어려움을 겪기도 하였고, 브루셀라가 농장을 강타하여 암소의 사육기반을 잃고 난 후 안정적으로 사육이 가능한 거세우 비육은 전환하여 현재는 거세비육에 전념하고 있다. 한편, 1994년부터 축산물등급제에 관심을 가지면서 육질부문에 심혈을 기울인 결과 오늘의 성공을 거두었다.

  • This article is based upon a talk given at the 1983 National Caving Conference explaining the types of personal computers available, their main features and how they could be used in connection with caving. There may be two groups of readers particularly interested in this subject, those covers with use of a computer who want some ideas on using it and others who want to know if getting a computer to use in connection with caving might be worth their while.

  • In this article, the writer attempted to study the followings: (1) mother's knowledge of milk feeding (including method of sterilization, formula and feeding) (2) reasons of artificial feeding (3) how much mothers are concerned about their artificial feeding infants (4) condition of growth and development of artificial feeding infants. As the object of study, 96 mothers with artificial feeding infants, who had consulted dep't of pediatrics of two Hospitals in Seoul (Korea Hospital and Med. College Woo Suk Hospital, Korea Uni.) and well baby clinic of the two Health Centers (Sung Dong and Dongdaemoon), were randomly sampled. The data were treated by the statistic method of chi-square and percentage, and come to the following conclusion. 1. Knowledge of milk feeding Sterilization: 70 percentages of mothers know about the milk sterilization (including bottle, nipple and instrument), but 55 percentages of them do not know the nipple sterilization correctly. Formula: 69 percentages of mothers follow the indicator or in accordance with doctor's directions, but 31 percentages do at their option by reasons that the baby often coughs up the milk, the baby is too small, the baby often has digestive troubles, or the baby grow fleshy heavily etc, except family economic problems. Feeding: only half of mothers know the correct feeding method, especially they do not know how to determine the heat degree of milk and how to bubble up the baby correctly. They just do feeding according to the accepted usages. 2. Reasons of artificial feeding Of the reasons of artificial feeding, 18 percentages were caused by infants and 82 percentages by mothers. Most of the reasons are mainly due to the lack of breast milk and sufficient supply of nourishments rather than mother's deficiency or mother's abnormality. 3. Mother's concern for artificial feeding infants Mothers who are sharply concerned for their artificial feeding baby's growth and development: 63%, mothers who made the baby (artificial feeding infant) routine vaccinated: 81%, mothers who ear anxious about the baby's future personality forming : 68%, mothers who care about the baby's condition of nourishment; 60%, mothers who are anxious about tile selection of baby's food; 54%. 4. The growth and development of artificial feeding infants compared with Korean average infants. The artificial feeding infants are above the Korean average infants in stature by 1.21 centimeters and in weight by 0.3 kilograms. Conclusion: It has been said that there is no better food for infant than the breast milk. However, the artificial feeding has been used for the supplement of nourishments and as substitute food for the breast milk. And this artificial feeding could give the married women the chance to act in society and more opportunity to develop themselves and to work for others at home and other fields. Considering these advantages, artificial feeding should not be exclusive, but preferably should be more improved and inquired positively. And even in artificial feeding, what is most important is that mothers should recognize the requirement and need of artificial feeding clearly and correctly, and they should be accustomed to the correct knowledge and skills of artificial feeding in order to practice it appropriately. In some degree, they should be properly trained in school education process.

  • A wide variety of cancer chemotherapeutic agents have been shown to induce programmed cell death (PCD, apoptosis) in various tumor cell fines in vitro. This study was performed to know how ginsenoside Rc affect on SK-MEL-28 cell line, and how they induce the apoptosis. SK-MEL-28 cell lines were treated with various concentrations of ginsenoside Rc and cultured for various times. At cell cycle analysis, cells arrested at G2/M phase by ginsenoside Rc and apotosis percentage increased along with increasing concentration and time. TUNEL assay was performed to know whether SK-MEL-28 cell fine die as apoptosis or necrosis by ginsenoside Rc. As a result, fluorescence increased along with increasing time and concentration. Fas expressed on SK-MEL-28 cell lines membrane by ginsenoside Rc was identified using flow cytometer. Ginsenoside Rc induced apoptosis against SK-MEL-28 cell fines, and the apoptosis mechanism was identified as Fas-mediated apotosis.

  • Ball screw systems are largely used in industry for motion control and motor applications. But the problem of noise, which really perplexes us, is highly correlated with the quality in ball screw systems all the way. In this paper, machining process parameters were evaluated in respects of technique, business, produce and quality to verify which impact influences the noise most. In order to adjust and compare, two comparison groups were set with the present parameters bench mark. Different ball screws were produced as specimens for the noise tests. Through comparing the noise performance of different parameters in the machining process respectively, a group of optimized machining process parameters were obtained. Another noise test was proceeded to know how noise performance was improved by optimizing the machining process parameters. At last, surface roughness tests have been done to know how surface roughness improved by optimization. The improvement of surface roughness is the main factor influences the noise performances.
