Background: The patcl test is widely used for diagnosis of allergic contact dermatitis. However, it is sometimes difficiilt or even impossihle to differentiate between allergic and irritant reactions in patch test readings. The achievernent of valid results from the patch test require intelligent and careful patch testing and physirians with skills and experiences. Objective : The purpos of this study was to assess the frequency, age and sex distr ibution, and the seasonal variatioii of irritant. and lost reactions in standard patch tests. Methods : Patch test records of day 2 and day 4 were reviewed and analysed. Frequency of inritant and lost reactions were analysed by allergen, age, sex and season. Results : A total 212 c ses of standard patch test records(rnale 69, female 143) were analysed. The results were as follovs ; 1. The over all frequency of lost reactions in the standard patch test were 33.5 percents and that of irritant reactions were 8.0 perr.ents. 2. The frequency of lost reactions was lower in the age groups under twenty(7.7%) than in the older age groups(35.5%). However, there was no significant difference het,ween the age groups over the third dec ide. 3. The seasonal variation was evident in lost reactions. The order of frequency was summer(45. 0% ), winf,er(33.7% ), spri,ig and fall(2l.1% ). 4. The order of frequency of lost reactions in the stclndard patch allergen was captan(5.7%), potassium dichromate(5.2%), cobalt chloride(4.7%), mercury amrnoniurn chloride(3.8%) c3lld wool alcohol(3.8%) Conclusion : Our result, show a relatively high frequency of lost and irritant. reaction in the standird patch test, and uggest second readings in the patch test would he of value.

VOF법은 유체 체적 비율을 통해 밀도가 다른 두 유체를 한꺼번에 계산할 수 있는 수치해석 기법이다. 상용 CFD프로그램의 VOF옵션을 이용하여 자유수면 부근에서 정속으로 움직이는 물체 주위의 수치해석을 시도하였다. 검증 대상으로는 물 속에 잠겨있는 2차원 날개, 자유수면을 수직으로 관통하는 3원 날개, 그리고 컨테이너 선형이 사용되었다. 검증 결과 정도의 차이는 있지만 상용 코오드의 범용성을 어느 정도 확인할 수 있었고 자유수면 유동장을 모사하는데 VOF법이 무난히 활용될 수 있음을 알 수 있었다. VOF method is known as one of the most effective numerical techniques handling two-fluid domains of different density simultaneously. Present study deals with the numerical analysis of flow field around bodies steadily moving near free-surface using FLUENT-VOF method. Validations were made by applying to three typical examples ; 2-D submerged hydrofoil, 3-D surface piercing body and container ship. It was found that the commercial software, FLUENT, is useful in practical use, and VOF method is capable of handling free-surface around moving bodies although discussions are limited to the analysis in qualitative sense.

Scleroderma is sclerosis of the skin characterized by the appearance of circumscribed or diffuse hard, smooth, ivory-colored anea that are immobile upon the underlying tissues and give the appearance of hide-bound skin. Several environmental factors and chemicals have been described as being able to induce systemic scleroderma and scleroderma-like diseases. A possible association between scleroderma and workers exposed to silica has been suggested by reports in the literature since the turn of the century. We report a 55-year-old man, with a history of Raynaud's phenomenon and dysphagia, who had been exposed to silica dust over fifteen years. He had a mask-like face, flexian deformity of fingers, and hyperpigmented induration on the skin of all the extremities and the trunk. Antinuclear antibodies were positive in nucleolar type. On radiologic study, streaky, mottled, and nodular increased densities were noted in the both lung fields and these findings were consistent with silicosis. Endoscopic and manometric examination of the esophagus represented scleroderrna esophagus. Histopathological findings were compatible with scleroderma. He was treated with azathioprine and nifedipine with good improvement. (Kor J Dermatol 1996;34(2): 322-325)

There are a number of studies on chemically strengthened glass. Most of them are strengthened in molten salt bath below transformation range of glass. This research is distinguished from the aforementioned studies in that single $KNO_3$ powder was used by employing screen printing technique. In this study soda-lime-silicate(SLS) glasses for bulletproof glass application with various thicknesses were used. The maximum value of the bending strength is 791MPa heat treated at $480^{\circ}C$, which is about 4.3 times higher than the parent glass, which is the highest strength of all soda-lime glasses. In this study, it is also observed that Vickers hardness increased to $657H_v$, which is about 15% higher than the parent glass($568.7H_v$) and fracture toughness was not changed. Depth profiles measured by electron probe micro analyzer(EPMA) showed a correlation between the migrations of $K^+$ ions with bending strength of ion exchanged glasses.
