고려인삼과 미국삼을 공시하여 Panax속 종간의 원료수삼 및 홍삼 등급에 기초하여 품질을 평가분석하였다. 1. 미국삼은 고려인삼에 비하여 근중이 적고 부정형 지근이 동체에서 많이 발생하는 관계로 체형이 불량하였다. 2. 홍삼수율은 고려인삼이 30.4%,미국삼이 33.8%로 미국삼이 높았고 홍삼의 본삼수율은 고려인삼이 80.4%, 미국삼이 72.2로 고려인삼이 높았다. 3. 원료수삼 1등급은 고려인삼이 미국삼에 비하여 2배정도 많았으나 2등급은 미국삼이 고려인삼에 비하여 많았다. 한편 고급홍삼인 천지삼율은 고려인삼이 미국삼에 비하여 높았다. 4. 홍삼 품질의 저하 원인은 고려인삼 미국삼 모두 내공과 내백 발생에 있었고 특히 미국삼은 내공에 비해 내백이 3배 가량 많이 발생하였다. 5. 홍삼의 지별 분포에서 고려인삼은 20지 이상의 대편급이 많았고 미국삼은 20지 이하의 소편급이 많았다.

인삼에 있어 다경 및 잠아 발생형태가 원료삼 및 홍삼 품질에 미치는 영향을 구명하고자 지하부 특성 및 품질요인을 조사하였다. 단경개체는 1-3개의 잠아를 갖는 형태이고 2경개체는 2-3개 그리고 3경개체는 3개의 잠아를 갖는 형태이었다. 또한 단경개체는 62.9% 그리고 2경 이상의 다경개체는 37.1%의 분포를 나타냈다. 원료삼의 등급은 단경개체에 비하여 다경개체가 될 수록 저하하였고 단경개체와 다경개체 모두 잠아수가 많은 개체에서 등급이 낮았다. 경수에 따른 홍삼수율은 대체로 30% 내외로 단경이나 다경개체간에 큰 차이가 없었다. 그러나 본삼수율은 다경개체로 갈수록 감소하는 경향이었다. 홍삼 등급은 다경개체에 비해 단경개체가 양호하였으며 다경개체는 양삼과 잡삼이 많았다. 그리고 잠아수가 많을수록 홍삼등급은 저하하였다.

The purpose of this study is to analyze the characteristics of environment-friendliness of Root Barrier materials based on comprehensive experiments on harmfulness of Root Barrier materials and fish toxicity of Oryzias latipes mortality to verify eco-toxicity of each method of construction and Root Barrier material, which are to be applied by taking eco-toxicity into account when building ecological flows in upper areas on natural and artificial grounds. As a result, the following conclusions have been reached in this study: 1. In regard of the harmfulness analyzed, each material showed a different result of analytical value in each lab tank. Compared to lab tank, pH (la), DO (lb), T-N (VI) and T-coli (la) were in the same grade, but COD, SS, T-P and F-coli were less than that of control, respectively increased or decreased by material were analyzed. 2. In the experiment of fish toxicity, Barrier sheet was found to have 66.7% of fish mortality, indicating strong fish toxicity. Synthetic rubber system root barrier sheet (20.0%) was analyzed to have medium fish toxicity, while Synthetic resin system root barrier-waterproof sheet (3.3%), Synthetic rubber system membrane root barrier sheet (3.3%) and Synthetic resin system root barrier sheet (0.0%) showed relatively lower mortality and fish toxicity. To sum up such results as found in the experiment mentioned so far, the values of harmfulness and root penetration resistance analyzed were different in each lab tank, but there was absolutely little correlation with the mortality gained from the experiment on fish toxicity. In the experiment of fish toxicity, environment-friendly root barrier materials were analyzed, and it was found that Synthetic resin system root barrier sheet, Synthetic resin system root barrier waterproof sheet and Synthetic rubber system membrane root barrier sheet are highly environment-friendly. In contrast, Synthetic rubber system root barrier sheet was found to have medium-level environment-friendliness. Also, Barrier sheet was analyzed to have low environment-friendliness.

Huang proposed a grey-based nearest neighbor approach to predict accurately missing attribute value in 2004. Our study proposes which way to decide the number of nearest neighbors using not only the dong's grey relational grade but also the wen's grey relational grade. Besides, our study uses not an arithmetic(unweighted) mean but a weighted one. Also, GRG is used by a weighted value when we impute a missing values. There are four different methods - DU, DW, WU, WW. The performance of WW(wen's GRG & weighted mean) method is the best of my other methods. It had been proven by Huang that his method was much better than mean imputation method and multiple imputation method. The performance of our study is far superior to that of Huang.

Purpose: Periodontal diseases are inflammatory conditions that alter the host's response to microbial pathogens. Type 2 diabetes mellitus (T2DM) is a complex disease that affects the incidence and severity of periodontal diseases. This study investigated the gingival crevicular fluid (GCF) levels of colony-stimulating factor-1 (CSF-1) and interleukin-34 (IL-34) in patients with stage III grade C periodontitis (SIII-GC-P) and stage III grade C periodontitis with uncontrolled type 2 diabetes (SIII-GC-PD). Methods: In total, 72 individuals, including 24 periodontally healthy (PH), 24 SIII-GC-P, and 24 SIII-GC-PD patients, were recruited for this study. Periodontitis patients (stage III) had interdental attachment loss (AL) of 5 mm or more, probing depth (PD) of 6 mm or more, radiographic bone loss advancing to the middle or apical part of the root, and tooth loss (<5) due to periodontal disease. Radiographic bone loss in the teeth was also evaluated; grade C periodontitis was defined as a ratio of the percentage of root bone loss to age greater than 1.0. The plaque index (PI), gingival index (GI), presence of bleeding on probing (BOP), PD, and clinical AL were used for clinical periodontal assessments. GCF samples were obtained and analyzed using an enzyme-linked immunosorbent assay. Results: All clinical parameters-PD, AL, GI, BOP, and PI-were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups for both the full mouth and each sampling site (P<0.05). The total IL-34 and CSF-1 levels were significantly higher in the SIII-GC-PD group than in the PH and SIII-GC-P groups (P<0.05), and there were significant differences between the periodontitis groups (P<0.05). Conclusions: These findings suggest that IL-34 and CSF-1 expression increases in patients with SIII-GC-PD. CSF-1 was associated with the inflammatory status of periodontal tissues and T2DM, while IL-34 was associated only with T2DM.

Aconiti Root(AR), has been used for about 2000 years, since recorded for low grade in 'Shinnongbonchokyung(Divine Husbandman's Herbal Foundation canon)'. It also recorded for Poisonous Drug in 'Myunguibyullok', 'Yaksungron', etc, and they advised when the AR is using for clinical desease it has to be processed. There are more than 13 processing methods, in records that related 39 parts which is recorded in ancient documents. In China, there are no standard of herb that using for clinical, cause of the traditional processing methods was cut since 1960s. In these days, they are using AR that recorded in Aconiti Tuber part of the processing records, in Guangdong and Shantung. In addition, the modification of Processed Aconiti Root(PAR) is also used for goods in Hongkong, Macao, and Southeast Asia. We studied the PAR for enhancing the importance of it, and multiply using. In this study, we search for the history of processing of AR, traditional theories of processing and clinical adaptation.

This paper discusses the application of civil structure use reinforcing fiber mixed with concrete to be used as protection layer of waterproofing material and root resistant layer installed in below-grade parking lot upper slab of residential building. A performance evaluation under the prescribed method outlined in KS F 4938 was used for this new material. The testing results showed that the fiber reinforcement can be used to strengthen the protection for the waterproofing material. Also, plants that were planted in June 2016 have not yet penetrated the specimens used for root resistance testing. The domestic root resistance performance testing usually covers the period of 2 years, thus further observation to make any conclusion about the root resistance property is required.

The author has studied comparatively the sealing quality of conventional Z.O.E. cement, Kerr sealer and Nogenol sealer by means of penetration of 2% methylene blue solution through the root apex of human teeth in 72 cases as time elapsed. The results were as follows; 1. All the specimens, whose dye immersion time is two days, showed dye penetration of low degree unrelated to the kinds of root canal sealer. 2. Kerr sealer group, like conventional Z.O.E. group, showed dye penetration of high degree related to increased time of immersion in the dye. 3. In Nogenol group, there was slight increase in penetration related to increased time of immersion in the dye. 4. Kerr sealer group showed comparatively lower grade of dye penetration than conventional Z.O.E. and higher than Nogenel sealer.

본 연구는 현재 수삼수납 시 품질검사요원의 관능검사로 판정되고 있는 6년근수삼의 적변판정에 대하여 영상분석기를 이용한 수삼의 적변 자동판정 시스템을 개발하고자 수행하였다. 영상분석기에 의한 수삼 총면적에 대한 grey valuequf 면적비율을 조사하여 이에 대한 회귀 및 판별분석을 실시한 결과, 정상삼과 적변삼을 구별할 수 있는 임계값은 총 면적에 대한 grey value 148에서의 면적비율(G148)로 분석되었으며, 임계값인 G(148)을 이용하여 다음과 같은 판별식을 구하였다. 적변삼의 판별식 : 6.67951$\times$G(148)+3.74122, 정상삼의 판별식 : 2.85942$\times$G(148)+9.95612, 본 판별식의 적중율은 89.8%로 이는 앞으로 계속적인 연구로 적변삼의 판정 적중율을 증가시킬 수 있을 것인 바, 컴퓨터 등 기계에 의한 적변 자동판정의 가능성은 매우 클 것으로 사료된다.
