We present VRI CCD photometry of W UMa type binary TY UMa. The light curves show that the secondary minimum is deeper than the primary minimum and the maximum I ($0.^{p}25$)is $0.^{m}023$ brighter than the maximum II ($0.^{p}75$). The V light curve has been analyzed and the photometric solutions have been determined by the method of Wilson & Devinney differential correction. We adopted the spot model to explain the asymetric light curve.

The flash point is one of the most significant combustion properties of flammable liquids in industrial processes when evaluation process safety, In this paper, Cleveland open cup tester is used to measure the flash points for the two binary systems (n-propanol + formic acid and acetic acid + propionic acid). The measured flash points were compared with the values calculated by the Raoult's law and the optimization method using van Laar and Wilson equations. The calculated values based on the optimization method were found to be better than those based on the Raoult's law.

UBV light curves of an early type close binary AQ Cas are made with the observations obtained at Yonsei University from 1982 to 1989. Light losses in U are shown at the phase around 0.55 and 0.90 which might be produced by the stream of mass transfer. Four times of minimum light derived from our observations. With the collected minima including ours, new light elements are determined. Phtometric solution with B and V light curves is made by using Wilson-Devinney codes.

Study on users which was done centering information approach, acquisition and interoperability between users and information systems need to be studied in the perspective of information behavior including information acquisition and sharing behavior in the changing information environment. In order to analyze users' information acquisition and sharing behavior's demands, motives and processes in libraries and internet environments, integrated approach of both qualitative and quantitative study were tried by applying Wilson's information behavior concept. Plans for the improvement of information services were suggested on the basis of integrative analysis.

Coherence and relevaned concern the ways in which discouse is interpreted.In this inversigation, the notions of coherence and relevance are discussed with examples in which they account for discourse interpretation and Charolles's(1983)procedural model of coherence is compared and combined with Sperber & Wilson's(1986a)Principle of Relevance. It is shown that the notion of coherence is not adeqiately established, but that the procedural approach will be a bridge between the prinxiples of coherence and relevance, each of which still remainas to be enriched and completed.

The written case that reflects the course of treatment for a person is central to the East Asian medical tradition. This paper examines the approaches and particularities of producing the actual written account of the clinical encounter, or a particular aspect of a case, that may be required by acupuncture practitioners and researchers. It will discuss the influences that can be brought to bear on the construction and production of these accounts. In addition, it will outline and highlight historical approaches to the case record documentation process as well as debate the value and purpose of these. This paper aims both to assist the production of helpful and authoritative case records for practitioners and researchers, and to highlight the usefulness of such case records. Moreover, it will discuss not only why the case needs to be written and for whom, but also which agencies support and control what is written. How can contemporary requirements and traditional views both be incorporated accurately, with context and with meaning? The essence of this paper is that practitioner/patient interactions need to be documented, and it will explore how this can best be supported.

A total of 583 observations (193 in ${\Delta}b$, 190 in ${\Delta}v$, 200 in ${\Delta}r$) for V523 Cas was made on 9 nights from September to December in 2008 using the 100 cm telescope with 2K CCD camera of the Chungbuk National University Observatory. With our data BVR light curves were constructed and 9 times of minimum light were determined. We also obtained physical parameters of the V523 Cas system by analysis of the BVR light curves using the Wilson-Devinney code.

Magnesium trisilicate was prepared by reacting Magnesium sulfate solution with Sodium silicate solution in this study. The optimum synthesis conditions base on the yield of the product were established by applying Box-Wilson experimental design. It was found that the optimum synthesis conditions of Magnesium trisilicate were as follows; Reacting temperature : $57{\sim}90^{\circ}C$, Concentration of reactant solution : $19.1{\sim}20.0%$, Molar concentration ratio of two reactants : [Sod.silicate]/[Mg.sulfate] : $1.47{\sim}1.80$, Temperature of washing water : $45{\sim}48^{\circ}C$, Drying temperature : $65{\sim}82^{\circ}C$. The antacidic capacity of the five Magnesium trisilicate samples which shows the maximum antacidic efficacy was tested by pharmacopeia acid consuming capacity test. The five Magnesium trisilicate samples were identified by chemical analysis.

Recently the interval estimation of binomial proportions is revisited in various literatures. This is mainly due to the erratic behavior of the coverage probability of the well-known Wald confidence interval. Various alternatives have been proposed. Among them, the Agresti-Coull confidence interval, the Wilson confidence interval and the Bayes confidence interval resulting from the noninformative Jefferys prior were recommended by Brown et al. (2001). However, unlike the binomial distribution case, little is known about the properties of the confidence intervals in finite population sampling. In this note, the property of confidence intervals is investigated in anile population sampling.

웅묘의 요도폐색의 외과적 치료법으로는 1971년 이후 Wilson의 회음요도루 조성술이 널리 사용되고 있다. Wilson법에선 요도와 피부를 직접봉합하나, 신축성이 없는 피부가 골반강방향으로 잡아 당겨져서 요도개구부가 좁아지기 쉽고 또 환축이 수술부위를 자주 핥으므로 봉합한 곳이 풀려지기도 하고 또 오줌에 의한 피부염이 일어나기 쉬운 결점 등이 있다. 그러나 이번 실험한 술기은 피부로부터 포피점막, 요도점막으로 이행시키기 때문에 피부가 요도구쪽으로 늘어나 이것이 작아질 염려가 전혀 없고. 오줌에 의한 피부염도 잘 일어나지 않는 이점이 있었다. 이것은 포피점막에는 신축성이 있고 그것이 양적으로 여유가 있기 때문에 더욱 요도가 수술후 골반강방향으로 매몰되기 때문에 봉합부를 환축이 혀로 핥을 수 없는 점은 대단히 이롭다.
