This study describes the manufacturing method of antioxidant filter and evaluate the reduction of free radical and biological activity from mainstream smoke. When we used spray-brush for the application of antioxidant solution to the filter, cv(coefficient of variation) levels of antioxidant added to filter ranged within 3 %, which means stable and constant feeding process. 0.3~0.5mg per cigarette of antioxidant were sprayed to acetate and active carbon part in the filter plug, respectively. It was considered that the use of antioxidant added filter resulted in the reduction of the gaseous compounds of free radicals from 17 % to 19 % in the mainstream smoke. Variation for removal efficiency of free radical in antioxidant filter added to acetate part was more pronounced than that of filter added to active carbon part. Smoking deliveries of tar, nicotine for the antioxidant added filters were similar when comparing to the non-antioxidant added filter, but the delivering amounts of isoprene were significantly reduced. The estimation of consumed GSH(glutathion) showed that the gaseous toxicity of the antioxidant added filter was 14 % ~ 23 % lower than that of non-antioxidant added filter. No significant differences were observed for the total taste quality in sensory evaluation.

Purpose: The purpose of this study is to help apply spiritual care in clinics by testing whether spiritual support like prayer and praise, which is appled on a patient who has been cared for by Facility Hospice can have an effect on their physical pain, emotional anxietv, loneliness and well being. Method: This research was done on a subject patient who had been hospitalized in Saemmul from Jan, 2002 to June, 2003, and who could easily communicate. Questionnaire of quality of life, they had this test from the date of admission into the hospital 1week, 3week, 5week later. The Target was 182 people for the hospital data, 124 people after one week, 84 people after 3 weeks and 54 people after for 5 weeks later. For statistics, SPSS for Window(SPSS inc. ver.10), student T-test and one way ANOVA were used. The interrelation between pray and pain was analyzed by the "Pearson correlation". In case where the P-value was below 0.05, we concluded it had statistical-value. Results: When we compared both the party which had a low degree of peace by prayer and praise and the B party which had the highest degree, B party had an increasing tendency for less anxiety and loneliness and more well-being. Each of the data 0, 1, 3 and 5 week showed visible difference between both parties. Conclusion: First, in case that a late cancer patient is hospitalized, the difference for tranquility and pain control by prayer and praise is not noticeable. While, 1 and 3 weeks later, the difference is visible, so we concluded the relationship between the cancer patient's spiritual tranquility and physical pain are closely related with each other. Also the patients who are in spiritual peace by prayer and praise can control the pain better than the other patients. Second, because the patient who can feel calm from the data of being admitted into the hospital is mentally calm, both party's difference is noticeable in each period of the 1, 3 and 5th week. Compared with other patients, the object patients who have spiritual tranquility will have less anxiety and loneliness and more tranquility.

This study was conducted to evaluate the effect of additives in low sidestream cigarette papers, such as Mg$(OH)__2,\;TiO_2\;and\;KH_{2}PO_4$ on the delivery of mainstream and sidestream smoke. From the analysis of tar and nicotine in sidestream and mainstream smoke, the delivered ratios of tar and nicotine by sidestream to mainstream smoke in common cigarette paper were 5.32 and 8.60, respectively. However, the delivered ratios of those of the paper containing $Mg(OH)_2\;were\;2.25\~3.23,\;4.86\~7.14,\;Mg(OH)_2\;and\;KH_{2}PO_4\;were\;2.12\~2.92,\;4.67\~6.89,\;TiO_2\;was\;3.21,\;7.51 $ respectively. The deliver patterns of semi-volatile components in the cigarettes were similar each there, but a slight different pattern in the amount was observed depending on the kinds of compounds added in cigarette papers. In the cigarettes made of $Mg(OH)_2$ added paper, the aromatic components such as benzene, toluene and phenol were generated more while the aliphatic components like neophytadiene, ethyl decanoate were delivered less than the cigarettes made of common cigarette papers. However, the cigarettes manufactured with $Mg(OH)_2\;and\;KH_2PO_4$ added paper showed an opposite trend. The cigarettes made of $TiO_2$ added paper showed relatively low delivery in the most compounds measured. In sensory evaluation, cigarette papers tested were noticed a distinguishable sensory character between the low sidestream smokes with additive cigarette papers except $TiO_2$ added one. Moreover, aroma patterns detected by a electronic nose system in TPM were a similar tendency.

김수호(Kim, Soo-ho) 한국문화융합학회 2017 문화와 융합 Vol.39 No.4

The objective of this research is to examine understandable and practical method to use church modals in Soo-ho Kim’s composition, “The Lord’s Prayer II” which is a mixed chorus in four parts. By the examination of the method to compose the piece, which is a combination of modality in medieval music and tonality in contemporary music, the author presents the possibility of interdisciplinary research between music theory and music composition. The uniqueness of musical language of each era is kept and handed down to next generation. The next generation develops it into new musical. It is truly significant that one composes new creation by blending and merging different distinctive musical languages which are extracted from each different eras. It is valuable to merge the medieval modality used for thousand years with the contemporary tonality in terms of combining a melodic elegance and vertical harmonic structure. At the same time it can be a phenomenon to create new musical of contemporary art music as interdisciplinary research within music field. As a result, this research will present the practical theory rather than abstract concepts of medieval music in terms of pedagogical aspect, and introduce the potentials of many different orientations of new creation based on medieval music in contemporary music. 본 논문의 목적은 김수호의 혼성합창곡 <주님의 기도 Ⅱ>를 통하여 중세 교회 선법의 쉬운 이해와 선법의 실질적 활용에 있으며 고음악 이론이 한 시대에 국한되어 머무르지 않고 시대를 초월하여 현대의 조성음악과 조화를 이뤄 새로운 음악어법으로 탄생되는 과정을 연구함으로써 시대가 다른 음악어법과 융합이 가능함을 제시한다. 각 시대마다의 음악어법은 독특함을 유지하며 다음 시대로 전달되고, 그 다음 시대에서는 전 시대의 음악어법을 또 다른 방법으로 발전시켜 새로운 음악어법으로 탄생되게 되는데, 이러한 시대별 각 음악어법의 중요한 특징을 추출하여 서로 다른 시대의 음악어법과 조화, 융합시킴으로써 또 다른 창작에 도전하는 것은 매우 뜻 깊은 일이라 할 수 있을 것이다. 중세 천 년 이상 사용되어 온 교회선법을 현대조성음악과 융합시킴으로써 중세의 선율선의 유려함과 조성음악의 수직화성체계에서 느낄 수 있는 풍부한 화성을 동시에 표출하는 새로운 음악어법의 탄생은 매우 의미 있고 가치가 있는 일이라 생각하며 음악융합의 한 모습을 보여주는 것이라 생각한다. 이러한 선법재료와 조성음악이 조화를 이루는 과정에서 두 시대별 음악어법에서의 나름 아쉽고 부족한 부분이 서로 충족되는 결과를 가져오게 되어 보다 신선한 음악어법으로 재탄생 항 수 있을 것이다. 이러한 연구의 결과는 새로운 창작에 많은 방향성을 제시할 것이며 또한 교육적 인 측면에서 고음악 이론의 실질적 활용을 제안하여 보다 고음악의 이론이 실제 음악에 활용될 수 있는 계기가 되리라 생각한다.

A theoretical model for predicting the capability curve of cellulose acetate filter is derived. The pressure drop is expressed as a function of the filter dimensions, the tow fiber characteristics, the filter weight, the fluid flow rate, and a filter fiber factor. Where, the filter fiber factor is affected by the distribution of the tow fibers within the filter, the relative orientations of the tow fibers, and their cross-sectional shapes. The minimum and maximum fraction of solids in capability curves determined from experimental data. Also, the filter fiber factor is expressed as a function of the filter length, tow fiber length, and tow fiber diameter. Capability curves predicted by the suggested model in this work correspond well with capability curves by experimental data.

Glycerol triacetate(triacetin) is the currently used common plasticizer in the making filters from cellulose acetate tow. For the mono acetate filter, the determination of triacetin contents is already established by CORESTA recommended method (No. 59). But unfortunately, the analytical method of triacetin in the activated carbon filter have not reported so far. In this study, it was established the analytical method of carbon filter's triacetin contents at various extraction conditions, bath ratio and internal standard materials. The confidential level appeared above $95\%$ when the extraction time, ISTD material and bath ratio was 3 hours, tripropionin and below 500 mg activated carbon / 50 $m\ell$ ethanol, respectively. Also, in the distribution of triacetin with filter materials in activated carbon filters, the triacetin amount was the most contained in activated carbon. Therefore, this method can be applied to the determination of triacetin contents in the activated carbon filter.

김수호,황갑성,홍성선 ( Soo Ho Kim,Kap Sung Hwang,Song Sun Hong ) 한국공업화학회 1997 공업화학 Vol.8 No.4

석탄의 종류와 농도 및 CWM의 유동성을 증가시키기 위해 첨가되는 계면활성제와 전해질이 CWM의 유동특성에 미치는 영향을 조사하였다. 탄종에 따른 CWM의 점도는 O/C 비가 높을 수록 높게 나타났다. 또한 CWM은 항복응력을 갖는 비뉴톤유체의 특성을 나타내며, 항복응력은 농도가 증가함에 따라 선형적으로 증가하였다. 첨가제로 사용된 계면활성제에 따른 CWM의 유동특성은 첨가되는 계면활성제의 농도에 관계없이 n< 1인 pseudoplastic의 특성을 나타내었다. 또한 전해질의 투입량이 증가할수록 n은 1로 접근하여 CWM이 뉴톤유체에 접근하는 것으로 나타났으며, 전해질을 0.05wt.% 이상 첨가하였을 때는 항복응력이 나타나지 않았다. We investigated that how both the type and the concentration of coal and the surfactant and the electrolyte added to increase the fluidity of CWM influence rheological characteristics. According to the type of coal, the viscosity of CWM was increased with increasing O / C ratio. Also, the CWM was represented the property of non-Newtonian fluid, having yield stress which was linerarly increased with increasing coal concentration. According to the surfactant used as an additive, the rheological characteristics of CWM was represented the pseudoplastic property as n < 1 without relating to the concentration of added surfactants. Also, according to the increase of the amount of electrolyte, n was nearly approached 1. Therfore, we found that CWM opproched Newtonian fluid and that when more than 0.05wt.% of electrolyte were added, yield stress was not shown up.

연소시 어려움이 많은 저급의 국내 무연탄을 입도별로 분류한(335, 200, 127, 90, 50㎛) 후 수직형 사이클론 연소기를 이용하여 공기공급비를 조절하며 석탄의 연소실험을 실행하여 입도에 따른 회분의 포집효율, 온도분포 및 연소효율을 조사하였다. 연소로 내의 온도 분포는 입경이 200㎛보다 큰 시료에서는 공기비 1.2에서 그리고 127㎛보다 작은 시료에서는 공기비 1.4에서 가장 높은 온도를 나타내고 회분의 포집효율은 공기비 증가에 따라 증가하였으며 연소효율은 입경이 작아질수록 증가되었다. The combustion characteristics of low grade anthracites having different particle size were studied by using the vertical-type cyclone combustor. The sample coals were sieved to have different particle size(335, 200, 127, 90, 50㎛). The combustion characteristics were obtained from temperature profile, amount of ash and unburned carbon, and nitrogen oxides[NO_x] in exhaust gas. The highest temperature in combustion chamber was recorded at air ratio of 1.2 for the samples larger than 200㎛ and at air ratio of 1.4 far the smaller than 127㎛. The value of carbon burnout was decreased with increasing the particle size, and the maximum value of that was obtained at air ratio of 1.4 in all sample. The NO_x emission of the effluent gas was increased with decreasing the particle size and increasing the air ratio as well as temperature.
