This study was carried out to determine optimum harvest time of in vitro multiplied tuber Pinellia ternata(Thunb.)Breit from 1990 to 1992. Tuber yield and its related traits were observed with four harvest times. Plant height was 7.2cm at 6 months and 19.3cm at 24 months after planting. The number of tubers per unit area was significantly increased with the passage of growing time after planting$(78\;tubers/m^2)$, those were increased by 2.3 times in 6 months, 5.6 times in 12 months, 13.3 times in 18 months and 20.0 times in 24 months. The tuber sizes(length, width and weight) were highly enlarged during 12 to 18 months after planting compared with before or after this time. There were smaller tubers and lower tuber yields with shorter growing period, while large tubers above 7.1mm and higher yields with longer growing. It was suggested that the optimum harvest time was 18 months after planting, before over wintering rather than next year of spring, 24months after planting.

Oral malodor is a problem that traverses history, culture, race and sex. But, up to the present the study on prevalence of oral malodor in normal popualtion is short, especially there is no study on oral malodor prevalence in Korean. In our study, we investigated self-evaluation of oral malodor, self-rating intensity of oral malodor, patients efforts for curing their oral malodor, and degree of satisfaction with their efforts. Investigation was carried out on 368 public Koreans resident in a big city(174 males, 194 females), by method of self-reporting to prepared questionnaire. There was no difference in self-reporting prevalence of oral malodor in sexes(57.5% in male, 58.8% in female), and the prevalence rate was increased with aging. Self-rating intensity of oral malodor in oral malodor patients group(by self-reporting) was ranked in order of slight, weak, middle, strong in both sexes, but the number of self-rating strong female group is significantly larger than that of self-rating strong male group(9.3% in male, 17.9% in female). In question on duration of oral malodor, most subjects answered that their oral malodor was developed in certain circumstances(61.3% in male, 76.3% in female), and oral malodor-developing circumstances was ranked in order of in the early morning, in hunger state, in fatigue, in stressful situations. Subjects effort for curing their oral malodor was ranked in order of more tooth brushing, gum chewing, use of commercial product for oral hygiene, visit dental clinic, and rates of no effort subjects were 15.3% in males and 10.7% in females. The degree of satisfaction with their efforts for curing their oral malodor was very low, only 5.6% of males and 6.6% of females were answered that there were satisfactory improvement in their oral malodor. Collectively, our result revealed that prevalence of oral malodor in public Koreans and their interest in oral malodor were much higher than our anticipation, and that patients satisfaction with improvement in oral malodor was short of their expectations. Considering the life quality of patients suffering from oral malodor, we conclude that developments of more improved diagnostic tools and treatment methods for oral malodor is indispensable in future.

The number of patients with dementia in Korea is estimated to be 576,000 in 2013 and 648,000 in 2015, and 840,000 in 2020 and 2,710,000 in 2050. Therefore, it can be expected that the number of patients with dementia will increase among the elderly patients who are looking for dentistry. Dementia and oral hygiene are closely related, so the future role of the dentist is very important. In order to treat effectively the patients with cognitive disorders, we should consider effective communication methods with them. Xerostomia is another important factor affecting oral health of dementia patients. In establishing the dental treatment plan, the most appropriate treatment method should be selected considering the characteristics of individual dementia patients and all possible efforts should be made for successful treatment results.

Destruction of oral soft and hard tissues and resulting problems seriously affect the life quality of xerostomic patients. Although artificial saliva is the only regimen for xerostomic patients with totally abolished salivary glands, currently available artificial salivas give restricted satisfaction to patients. The purpose of this study was to contribute to the development of ideal artificial saliva through comparing viscosity and wettability between CMC solutions and human saliva. Commercially-available CMC is dissolved in simulated salivary buffer (SSB) and distilled deionized water (DDW). Various properties of human whole saliva, human glandular saliva, and a CMC-based saliva substitutes known as Salivart and Moi-Stir were compared with those of CMC solutions. Viscosity was measured with a cone-and-plate digital viscometer at six different shear rates, while wettability on acrylic resin and Co-Cr alloy was determined by the contact angle. The obtained results were as follows: 1. The viscosity of CMC solutions was proportional to CMC concentration, with 0.5% CMC solution displaying similar viscosity to stimulated whole saliva. Where as a decrease in contact angle was found with increasing CMC concentration. 2. The viscosity of human saliva was found to be inversely proportional to shear rate, a non-Newtonian (pseudoplastic) trait of biological fluids. The mean viscosity values at various shear rates increased as follows: stimulated parotid saliva, stimulated whole saliva, unstimulated whole saliva, stimulated submandibular-sublingual saliva. 3. Contact angles of human saliva on the tested solid phases were inversely correlated with viscosity, namely decreasing in the order stimulated parotid saliva, stimulated whole saliva, unstimulated whole saliva, stimulated submandibular-sublingual saliva. 4. Boiled CMC dissolved in SSB (CMC-SSB) had a lower viscosity than CMC-SSB (P < 0.01 at shear rate of $90s^{-1}$). 5. For human saliva, contact angles on acrylic resin were significantly lower than those on Co-Cr alloy (P < 0.01). 6. Comparing CMC solutions with human saliva, the contact angles between acrylic resin and human saliva solutions were significantly lower than those between acrylic resin and CMC solutions, including Salivart and Moi-Stir (P <0.01). The effectiveness of CMC solutions in terms of their rheological properties was objectively confirmed, indicating a vital role for CMC in the development of effective salivary substitutes.

박문수,서성,한영춘,이종경,Park, Moon-Soo,Seo, Sung,Han, Young-Choon,Lee, Joung-Kyong 한국초지조사료학회 1988 한국초지조사료학회지 Vol.8 No.3

本 실험은 林間草地의 改良과 管理 및 利用에 관한 基鍵資料를 얻고자 趣光程度를 0%區(無週光區), 25%, 50%, 75%로 인위적으로 조절하고. orchard grass, timothy, perennial ryegrass, ladino clover를 供試하여, 일반成分, 세포벽構成物質(CWC),,消化率, 可溶性탄수化物 (WSC) 함량 및 실산유실요 (NO, - N) 含量등을 分析하였으며 1985년도 축산시험장 草地시험포에서 수행되었다. 1. 一般成分과 CWC含量 및 消化率을 고려해 볼 때 ladino clover가 화본과목장에 비해 품질이 좋았으며, 未本科목장중에서는 perennial ryegrass의 品質이 좋았다. 2.粗蛋白質, 조회분 및 消化率은 草種에 관계없이 차광을 많이 할수록 增加하였으며, 粗織維系 統은 차광을 많이 할수록 未本科救草에서는 減少하였으나 ladino clover에서는 오히려 曾加하였다. 3.利用時期에 따른 목초의 消化率은 봄철에 자란 목초는 여름철 고온조건하에서 자란 옥초에 비해 良好하였다. 4.草種別 WSC 含量은 perennial ryegrass>ladino clover$\geq$orchardgrass$\geq$timothy 順이었으며 차광을 많이 할수록 WSC含量은 減少하여 (P< 0.05) 無遮光區$\geq$25%週光區$\leq$50%차광구$\geq$75%차광구 순 이었다. 5.草種別 NO,-N 含量은 perennial ryegrass orchardgrass ladino clover timothy 順이었으며, 차광을 많이 할수록 $NO_3$-N含量은 급격히 增加하 여 (P< 0.05) 75%차광구>50%차광구 25%차광구 無차광구 순이었다. 차광정도와 $NO_3$-N 함량과의 회귀식에서($r^2$=0.90**,$r^2$=0.95**) 43~44% 이상의 차광은 실산중독 위험수준 이상이었다. 6. 以上의 결과로서 임간초지개랑시에는 가축에게 실효중독을 야기시키지 않고 목초의 품질과 수량등을 고려한 한계 차광정도는 40%정도(자연광량의 60% 以上 受光條件)로 생각된다. A field experiment was conducted to determine the effects of shading degrees (0: full sunlight, 25, 50 and 75%) on the proximate components, cell wall constituents (CWC), digestibility, water soluble carbohydrates (WSC) and nitrate nitrogen ($NO_3$-N) concentration of grasses grown in forest. For the test different artificial shading houses were established and pasture species used were orchardgrass, timothy, perennial ryegrass and ladino clover. The experiment was performed at LES in Suwon. 1985. 1. Considering proximate components, CWC and digestibility of grasses, ladino clover showed the best quality, and then perennial ryegrass. 2. The contents of crude protein, crude ash, and digestibility of grasses were increased with shading, regardless of pasture species. As the shading degrees are increased, the contents of crude fiber in orchardgrass, perennial ryegrass and timothy were decreased, while that in ladino clover was increased with shading. 3. Grasses grown in spring showed higher digestibility than those grown in summer season. 4. The content of WSC was the highest in perennial ryegrass, and then ladino clover, orchardgrass, and timothy, in that order. Also WSC was decreased as the shading degrees are increased. 5.The content of $NO_3$-N was the highest in perennial ryegrass, and then orchardgrass, ladino clover and timothy, in that order. Also the $NO_3$-N was significantly increased with higher shading level. In the regression equation between shading degrees and $NO_3$-N ($r^2$=0.90**, $r^2$=0.95**), shading degree of 43 to 44% was critical level, causing nitrate poisoning to animal. 6 Considering grass quality, dry matter yield and $NO_3$-N, less than 40% of shading degree (over 60% of full sunlight) was desirable for better grassland improvement, management and utilization in the forest.

박문수 ( Moon Soo Park ),김예지 ( Ye Ji Kim ) 한국고무학회 2014 엘라스토머 및 콤포지트 Vol.49 No.3

수용성 단량체인 아크릴산 (AA)을 단량체로 potassium persulfate (KPS)를 개시제로 이용하여 60℃에서 90℃ 사이의 선택된 온도에서 물을 반응매체로 하여 용액중합을 진행하였다. 아크릴산의 농도가 감소하거나 개시제의 농도가 증가하면 분자량은 감소하였다. 중합반응온도를 상승하면 폴리아크릴산 (PAA)의 분자량은 감소하였다. 대부분의 중합반응에서 분산성지수는 1.5 에 근접하는 것으로 관찰되었다. 교반속도가 증가하면서 400 rpm에서 분자량은 최고값을 나타낸 후, 교반속도가 800 rpm에 이르면서 수평균 및 중량평균분자량은 감소하였다. 유리전이온도는 분자량에 따라 크게 변하지 않았으며 113℃에서 116℃ 사이의 값을 나타내었다. Solution polymerization was conducted with water-soluble acrylic acid (AA) as a monomer and potassium persulfate (KPS) as an initiator at a selected temperature between 60℃ and 90℃ with water as a reaction medium. When the ratio between AA and water was reduced or initiator concentration increased, molecular weights decreased. An increase in the reaction temperature produced lower molecular weights. The polydispersity index was close to 1.5 in most of the reactions. An increase in the stirring speed up to 400 rpm led to a progressive increase in molecular weights. When the stirring speed reached 800 rpm, however, we found that both the number and weight average molecular weights decreased. The glass transition temperature was nearly independent of moelcular weights and determined to be between 113℃ and 116℃.

카본블랙의 농도 및 단량체 구성비에 따른 스티렌-부틸메타크릴레이트 공중합체 입자의 유동성

박문수 ( Moon Soo Park ),문지연 ( Je Yeon Moon ) 한국고무학회 2010 엘라스토머 및 콤포지트 Vol.45 No.2

소수성실리카를 안정제로 하는 현탁중합반응법을 이용하여 합성한 스티렌(St)/부틸메타크릴레이트(BMA) 공중합체 (co-PSB) 입자의 전단점도를 모세관 레오미터 (capillary rheometer)를 이용하여 170℃에서 측정하였다. co-PSB 입자의 전단점도는 중량평균분자량이 74,800 g/mol 이하인 경우 낮은 전단속도에서는 뉴톤거동을 보였다. 중량평균분자량이 136,800 g/mol을 초과하면서 전단점도는 전단속도의 전 영역에 걸쳐 감소하였고 전단속도에 대한 기울기의 절대값은 분자량의 증가와 함께 증가하였다. St/BMA의 구성비가 7/3, 5/5 및 3/7의 co-PSB 입자는 유사한 분자량을 나타내었지만 BMA의 구성비가 증가하면서 유리전이온도와 전단점도는 감소하였다. St/BMA의 구성비가 1/9 인 co-PSB의 경우 유리전이온도는 더욱 감소하였으나 초기 전단점도는 크게 증가하였다. 카본블랙을 함유하는 co-PSB 복합체 입자의 전단점도는 카본블랙의 증가에 따라 증가하였으나, 카본블랙의 농도에 따른 전단점도의 변화는 분자량 및/혹은 구성비의 변화 효과에 비교하여 미약하였다. We measured shear viscosity of copoly(styrene(St)/butyl methacrylate(BMA)) (co-PSB) particles, with a capillary rheometer at 170℃, prepared by suspension polymerization with hydrophobic silica as a stabilizer. co-PSB particles with the weight average molecular weights of lower than 74,800 g/mol displayed a Newtonian behavior at low shear rates. With the weight average molecular weight exceeding 136,800 g/mol, co-PSB particles showed shear thinning against shear rates and the absolute value of the slopes between shear viscosity vs. shear rate increased. When the ratio between St and BMA changed from 7/3 to 5/5 to 3/7, shear viscosity and glass transition decreased despite similar molecular weights. When the ratio was 1/9, it showed a large increase in initial shear viscosity despite reduced glass transition. Shear viscosity exhibited an increase in proportion to carbon black concentration. The effect of carbon black concentration on the shear viscosity of co-PSB composites was less pronounced compared to varying molecular weights and/or compositional ratio.
