Four point bending tests of the brazed joint composed of sintered silicon nitride and 0.2% carbon steel with Cusil ABA filler which were fabricated at 86$0^{\circ}C$ were performed at temperatures, 25, 100, 200, 300, 400, 50$0^{\circ}C$ From the experiments, the maximum bending strength was measured at 30$0^{\circ}C$ From the 3D FE analysis of the residual stress of the brazed joint, it was revealed that the thermally induced residual stresses were minimized when the environmental temperature was 35$0^{\circ}C$ Considering the degradation of the filler material at high temperatures, it was calculated that the maximum bending strength of the brazed joint occured just below the temperature of the minimum thermal residual stress and the thermal residual stress was the dominative parameter of the brazed joint.

Objectives: This study examined the effects of Gamisachil-tang on an anorexic patient with depression. Methods: A patient suffering from anorexia and depression was treated with Korean herbal medicine (Gamisachil-tang) for 14 days. To evaluate the therapeutic effect, we measured the daily food intake of the patient and used the Visual Analogue Scale (VAS) for anorexia. Results: Following treatment, both the patient's daily food intake of the patient and VAS score for anorexia had improved. Conclusion: These results suggest that Gamisachil-tang has a beneficial effect on both anorexia and depression.

Objectives Children's unique taste bud often gives them difficult time to take oriental medicines. To overcome, survey was conducted focusing on useful and practical tips on how to take them. Methods The survey was carried out by posting mail questionnaire. Target clinics for the survey were selected by the internet search engine, Google, Daum, and Naver, and typing in "oriental treatment + pediatrics", "pediatrics + oriental medicine", "pediatric oriental clinic". 24 clinics were searched, but they were further narrowed down to the specialized pediatric oriental clinics. Also, total of 38 inquiry leaflets were distributed to 14 University Oriental Hospitals. Results If children refuse to take the medicine, mixture with sweeteners can be prescribed for them. Among them, oligosaccharide is the most recommended followed by sugar and honey. To avoid rejection to medication, use of different formulation, such as distillation medicine, soft X-Section, granulated medicine, and character printing can be used. Conclusions The most effective method is to investigate the mixture first, and then the alternative formulations.

어느 고독한 철학자의 몽상

이수정,Lee, Su-Jeong 한국대학교육협의회 1999 大學敎育 Vol.97 No.-

IMF로 상징되는 '한국의 추락'을 겪으면서 '전 존재의 경제화'라는 경향을 섬뜩한 심정으로 지켜보고 있다. 이것을 방치할 경우 맞이할 또 다른 위기가 손에 잡힐 듯 보이지만 이미 '대학'도 '교육'도 '철학'도 떨어진 낙엽처럼 짓밟히고 있다. 세상은 이것들을 더 이상 '존경'하지 않는다. 그래도 이것들이 '숭고한' 어떤 것이라 믿고 매진해 온 사람들은 그 이념을 버리지 못하고 오늘도 고민한다. 살다보면 언젠가 철학의 목소리가 아쉬워 인터뷰를 요청해 올 날이 있을지도 모른다. 그 때를 위한 예행연습 한 토막을 적어 본다.

The purpose of this study was to evaluate the shock absorbing effect of 4 restorative materials and intramobile connector. The damping effect of four restorative materials used to veneer test crown rigidly connected to IMZ implant and subjected to an impact force was measured. These materials included a gold alloy(stabilor G) : a noble metal ceramic alloy(Degudent H) : porcelain(Duceram) : composite resin(Dentacolor). In addition, this study compared damping effect of same restoretive materials after using polyoxymethylene intramobile connector(POM IMC). The result of this study suggest that : In case of using metal IMC 1. Veneered composite resin(group IV) reduced the impact force by 75%, when compared to an equivalent thickness of porcelain(group III). Group IV reduced the impact force by 87% and 89%, respectively, when compared to Stabilor G(group I) and Degudent H(group II). 2. The impact force recorded was higher for the alloy with the higher elastic modulus.(Stabilor G, group I, Young's modulus 107 Gpa, versus Degudent H, Group II, Young's modulus 95 Gpa) 3. It took the longest time for composite resin veneered group(IV) to reach to peak force when compared group I, II, III. In case of using POM IMC 4. The mean impact force recorded were reduced by 79%(group I), 78%(group II), 69%(group III), 84%(group IV), respectively, when compared to using metal IMC. 5. The time required to reach the peak force were increased by 78%(group I, II) 87%(group III), 34%(group IV), respectively, when compared to using metal IMC>.

Texture electron diffraction pattern을 이용한 결정구조 해석 이론은 러시아어로 씌여졌거나, 영문판 저서의 일부에 간단히 소개 되어있어 이해에 어려움이 있다. 이들의 이론은 벡터의 이론과 관련된 여러 관계식을 이용해서 설명될 수 있으며, 이로서 몇 개의 식에 포함된 오류를 수정하였다. The works of texture electron diffraction patterns for crystal structure analysis are written in Russian or introduced briefly in books written in English, which makes it difficult to be understood. In addition to working out the equations, vector theory corrects some errors included in the established formulas for texture electron diffraction patterns.

한반도 남부지역에서 산출되는 카올린광물의 고온영역에서의 광물학적 특성 연구

Dehydroxylation and mullitization of primary and secondary kaolins were investigated in order to compare and understand the differences in thermal behaviours by DTA and TG up to $1,100^{\circ}C$. Chemical analyses and EPMA of the samples revealed nearly ideal unit-cell formulae of kaolins. The weight losses of dickite and halloysite are 14% and 12.5% on the average, respectively. The activation energies of dehydroxylation of kaolin minerals were calculated according to Kissinger's approach which uses various heating rates in DTA to estimate the activation energy of thermal reactions. The activation energies of dehydroxylation of halloysites from Daemoung and Buksam mines are about $163kJmor^{-1}$ (white), $168kJmor^{-1}$ (pink), and $176kJmor^{-1}$ respectively. The activation energies of dickites collected from Sungsan and Ogmae mines are about $166kJmor^{-1}$ and $387kJmor^{-1}$. The asymmetric shape of endothermic peak in DTA, the relative intensities of OH-stretching bands in FTIR spectroscopy and the existence of residual XRD peaks of the samples which were heated at $550^{\circ}C$ for 2 hours indicate that Sungsan dickite may be more disordered than Ogmae dickite. The new phase formed in thermally treated samples in the range of $900^{\circ}C$ to $1,100^{\circ}C$ was identified as mullite by XRD on the basis of disappearing of the characteristic peaks of kaolins and increasing of amorphous background upon heat treatment. On further heating, loss of more water from dehydroxylate resulted in the formation of mullite and the characteristic X-ray diffraction patterns of mullite began to appear at about $900{\sim}1,000^{\circ}C$ in kaolins.

In this paper, design of small microprocessor unit is implemented using research purpose VHDL and CAD tools by top-down design method. For this, original basic MPU and its pipelining architectures are suggested. Once, design target, instruction sets, architecture are decided, the operation is confirmed by C language simulation, and then the operation is confirmed by checking internal register contents for given inputs in the case of VHDL simulation. Then, design layouts are made by full/semi-custom design methods by research CAD tools and related simulation is implemented. The feasibility of suggested pipelined structure for performance improvement is confirmed by simulation, and related problems and future research directions are discussed. In conclusion, the MPU design methodology is set up and the design change of architecture is possible by this paper.
