강성현(Seong-Hyeon Kang),김태형(Tae-Hyung Kim) 한국지반신소재학회 2014 한국토목섬유학회 학술발표회 Vol.2014 No.11

Settlement prediction has been conducted using Hyperbolic, Hoshino, and Monden methods, etc in the fields. These methods are only able to predict settlement after finishing the final filling stage. A new method is proposed to make up for such a weak point. This method was named as Kang"s method, which can be able to predict the settlement both the final filling stage and the staged filling from the initial filling stage in soft ground. To verify the applicability of this method, the measured settlement curve history was compared with the predicted one. The predicted settlement is well matched with the measured one. From the study, the Kang"s method can be possible to predict settlement during the staged filling with only the initial settlement data.

Kang,Mi-Hyung,Lee,Du-Ku,Noh,Tae-Hwan,Shim,Hyeong-Kwon,Na,Seung-Yong,Kim,Jae-Duk 한국자원식물학회 2004 Plant Resources Vol.7 No.1

We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.

강부경,이종섭,신태용,이은희,김형민 원광대학교 생명공학연구소 1996 생명공학연구소보 Vol.4 No.1

We determined for IgE in serum based on the enzyme-linked immunosorbent assay(ELISA) in vivo after intraperitoneal injection of Solanum lyratum extract for 14 days. The experiment showed as well whole spleen cells that Solanum lyratum extract enhanced IgE production in vivo. Solanum lyratum extract significantly facilitated the production of IgE by LPS-stimulated murine spleen cells. Solanum lyratum THUNB. also enhanced IgE production from mouse whole spleen cells. Lypopolysaccharide(LPS) stimulated IgE production was enhanced 1.4-fold to 2.7-fold by the addition of Solanum lyratum extract over a period of 7 days.

한라산 1100고지에서 채취한 대기 에어로졸 조성의 계절적 변화에 관한 연구

강창희,한지숙,김태행,김원형,박용이 濟州大學校 基礎科學硏究所 1997 基礎科學硏究 Vol.10 No.1

The atmospheric aerosols have been collected with aerosol sampler installed at 1100m site located at Halla mountain in Cheju island for about 124 days from August 15, 1996 to May 3, 1997, and their compositions have been analyzed in order to investigate the seasonal variation of aerosol compositions and the characteristics of aerosols. The correlation coefficients for the sum of the cation and anion equivalent concentrations showed the values between r=0.911 and r=0.977, and it has been found that the precision of the analytical data was with good satisfaction. The amounts of total suspended particulates(TSP) were in the range of 19.9∼28.6μg/㎥ with the highest concentrations in Spring season due to the yellow sand effect. The average concentrations of water-soluble cations were in the order of NH₄ +>Na+>Mg²+>K+>Ca²+ during the summer, fall and winter seasons, but NH₄+>Ca ²+>K+>Na+>Mg²+ during the spring season. The average concentrations of anions were in the order of SO₄->NO₃->Cl- for the all seasons. The concentrations of SO₄²- and NO₃- showed a high increase through winter and spring seasons due to the effect of the north-west wind, which were 5.95∼6.05μg/㎥ and 1.41∼1.60μg/㎥ respectively. And the Ca²+, the major component of soil, showed a high concentration value of 0.47μg/㎥ in yellow-sand spring season. In the effect of sea-salt with the enrichment factors, the SO₄²-, Ca²- and K+ were found to be flown to the air due to the other factors rather than sea-salt effect. And in the effect of soil with the enrichment factors, the SO₄²-, NO₃-, Cl- and NH₄+ were found to be introduced to the air through the other paths but the soil itself.

납동위원소비법에 의한 영광 수동유적 청동기의 산지추정

강형태,정광용,이기길 호남고고학회 2002 湖南考古學報 Vol.15 No.-

본 연구는 전남 영광군 화평리 수동마을 움무덤에서 출토된 새무늬 청동기 및 본뜬거울(방제경)을 주조하기 위해서 어디에서 원료를 가져다 썼는지 그 산지를 추정한 결과이다. 청동기의 원료산지를 추정하는 방법중의 하나로서 납동위원소비법을 사용하였다. 즉, 청동기에 함유된 납의 동위원소비를 분석한 다음 기 확보된 한국·중국·일본 방연광의 납동위원소비 분포도를 비교하여 어느 군(group)에 소속되는지를 살펴보았다. 또한 다변수분석법중 선형판별식분석으로 작성한 방연광 분포도를 사용하여 위의 결과와도 잘 일치하는지를 확인하였다. 납동위원소비 분석결과 새무늬 청동기는 중국 북부산 방연광 분포 범위에 포함되었는데 이는 선형판별식분석 결과와도 일치하였다. 본뜬거울은 중국 남부산의 방연광에 속하는 것으로 생각되나 한국 남부산 방연광 일부와도 인접해 있어서 명확하게 판단하기에는 어려움이 있다. 또한 위의 결과를 종합하면 동일 움무덤에서 출토된 청동기이지만 원료의 출처는 서로 다르다는 것을 반영하고 있다. 청동기 원료의 산지추정을 위해서는 성분조성비 분석도 함께 이루어져야 하나 대부분 부식되어 분석이 불가능하였다. 그러나 이들 납동위원소비 데이터는 차후 호남 문화권의 청동기연구에 있어서 좋은 참고 자료가 되리라 판단된다. Five lead isotope ratios(206/204, 207/204, 208/204, 207/206, 208/206) of two bronze artifacts excavated from Sudong site, Youngkwang-gun were analyzed by TIMS(thermal ionization mass spectrometer). Their lead isotope ratio data obtained were compared with those of galena of Korea, Japan and China, which data were being used for reference raw material data set. And multivariate mapping method such as statistical linear discriminant analysis(SLDA) was applied to classify the sources of raw materials. The lead isotope data of bronze artifact decorated with bird design was included in the area of galena of northern China and this result was accorded with SLDA result. Imitated bronze mirror was of southern China but very difficult to differentiate with area of south Korea. Consequently, the result of lead isotope ratios of two bronze artifacts suggested that the sources of raw materials were different origin each other.

姜炯台,李澈,諸元穆 漢陽大學校 環境科學硏究所 1989 環境科學論文集 Vol.10 No.-

조선시대 자기의 특성화를 위하여 중성자방사화분석법으로 15개의 미량성분원소 (Sm,Ga,K,La,Ce,Yb,Th,Hf,Na,Cs,Sc,Rb,Fe,Co,Eu) 함량을 결정하였다. 데이타의 수학적 처리법으로서 선형판별식분석법을 사용하였다. 이 선형판별식분석법으로서 자기의 분류에 유용한 변수를 선정한 다음 재차 선형결합방식으로 분류규칙을 구하였다. 판별점수로서 평면상에 도시한 결과 경기도 광주군 상번천리5호, 상번천리9호 및 도수리 청·백자의 분류효율은 각각 12/15,15/15,10/10이었다. Data on the concentration of Sm,Ga,K,La,Ce,Yb,Th,Hf,Na,Cs,Sc,Rb,Fe,Co and Eu obtained by neutron activation analysis have been used to characterize Korean porcelain by multivariate analysis. A combination of analytical data by means of statistical linear discriminant analysis(SLDA) has resulted in removal of redundant variables, optimal linear combination of meaningful variables and formulation of classification rules. The plot in the first-to-second discriminant scores has shown that the three distinct territorial regions exist among porcelains of Kyungkido Sangbunchulli No. 5, Sangbunchulli No. 9 and Dosuri, with respective efficiencies of 12/15,15/15 and 10/10.

수동유적 움무덤 출토 유리구슬의 화학조성

강형태,정광용,이기길 호남고고학회 2003 湖南考古學報 Vol.18 No.-

전남 영광군 화평리 수동마을 움무덤에서 출토된 유리 시료 18점의 화학조성을 분석하기 위하여 주사전자현미경에 부착된 파장분산형 X-선 분석기를 사용하였다. 유리구슬의 색깔은 크게 녹청색, 감청색, 감색 및 투명한 것으로 나뉘었다. 각 시료에 대하여 10종의 산화물을 분석한 결과 투명유리를 제외하고는 모두 칼리계 유리로서 K2O 함략이 17.2~19.6% 범위였다. 투명유리는 다른 유리구슬에 비해 실리카 함량이 93~94%로서 높고 K2O 함량이 2~4%인 비결정성 물질임을 X-선 회절분석으로 확인하였다. 녹청색 유리는 구리가 착색원소로 착용한 것이며 감청색 및 감색은 미량의 코발트 성분이 착색원소로 작용한 것으로 추정되었다. 감청색과 감색의 차이를 성분 함량으로 살펴본 결과 감청색은 망간의 농도가 1% 이하이고 감색은 1.4~1.8%의 농도를 나타내었다. 이 분석결과는 전남 영광지역의 철기시대 유리제작기술을 알려주며 이러한 분석 사례가 쌓이면 시대별, 지역별 유리의 특성을 밝히는 연구도 가능할 것이다.

生物膜濾過 전처리수의 Floc形成 및 沈降特性에 관한 硏究

姜龍太,金泰亨,金泳珍 東亞大學校 海洋資源硏究所 1989 硏究論文集 Vol.2 No.1

The existing clean water system in Pusan have several problems in purifying the contaminated water in the Nakdong river. This suggests that the existing system has to be supplemented by an advanced processes. This research were carried out to evaluate the treatment characteristics of the biofilm process as pretreatment and to obtain the optimum values of velocity gradient and flocculation time with coagulant dosages. The results showed that the biofilm process was adequate as the pretreatment prior to the flocculation and sedimentation process and that the optimum velocity gradient increased in proportion as the flocculation time decreased and, for both the water without and the water filtrated through the biofilm, the optimum G values all were approximately 30 sec??. The pretreatment by the biofilm process was effective in minimizing the residual turbidity in sedimentation basin.

국립중앙박물관은 용산 새 박물관의 전시 유물로 선정된 중앙아시아 벽화의 연차적인 보존처리를 위해 “독립행정법인 일본 도쿄문화재연구소’’와 공동연구를 모색하게 되었다. 2001년에 본4074, 본4096 작은 벽화편 2점의 보존처리를 시작하면서 벽화의 균열 박락 등 손상상태, 구조와 구성재료, 이전 보존처리에서 적용된 재료와 방법에 대한 기초조사를 실시하였다. 조사결과 본4074, 본4096 2점의 벽화는 흙과 지푸라기를 반죽하여 만든 벽체에 석고를 발라 바탕으로 하고 그 위에 채색을 한 것으로 나타났으며 벽체 속에 포함된 지푸라기의 방사선 탄소연대측정 결과 본 벽화는 10세기 말에서 13세기 초에 만들어진 것으로 나타났다. 또한 X-선회절 분석 결과 화면의 흰색 바탕은 gypsum[Ca(SO₄)·2H₂O]과 CaSO₄, Calcite(CaCO₃)가 적색계통은 연단(鉛丹:Pb₃O₄)과 led arsenate[Pb(As₂O₆)], 녹색계통은 Cuprite(Cu₂O)와 arsenolite(As₂O₃), arsenic oxide(As₂O₄) 등이 사용된 것으로 조사되었다. This article is about a joint project carried out by the National Museum of Korea and the Tokyo Cultural Properties Research Institute for the conservation of central Asia Wall painting that has been selected for the exhibition at the new Seoul National Museum of Korea at Yongsan. The investigation of the wall painting revealed very useful information. This includes the condition of the object, and the identification of evident damage, such as cracks, loss of pigment, plus materials and methods employed during the object's creation, as well as previous conservation treatment. The object was mainly made by applying plaster to the body (wall) that consisted of a mixture of soils and rice straws. Then, on the surface of the wall-painting, pigments were used to draw and to colour it. As a part of the investigation, radiocarbon dating was conducted using straw samples taken from the object. The result indicates that the object is probably dated form between the end of the 10th Century and the beginning of the 13th Century. The result of X-ray diffraction also revealed the composition of the pigments used on the surface. These are 1. gypsom[Ca(SO₄)·2H₂O], CaSO₄ and Calcite(CaCO₃) and Calcite(CaCO₃) that were used for the white background. 2. Pb₃O₄ and led Arsenate [Pb(As₂O₆) that were used for the red colouring. 3. Cuprite(Cu₂O), Arsenolite(As₂O₃) and Arsenic Oxide(As₂O₄) that were used for the green colouring.

政治, 經濟, 經營的 側面에서 考察한 日本의 發展戰略에 관한 硏究

姜太勳,田馨,李光周 韓日經商學會 1994 韓日經商論集 Vol.10 No.-

The purpose of this paper is to explore the key factors which brought on the Japan's high speed economic growth in the postwar periods. There are largely two approahes which deal with this issue: the state-business relations and the Japanese style management. This study undertook critical reviews on the existing literatures. There are four models in the state-business relations: bureaucratic-led devlopment model; market oriented model; network model; and corporatism. Considering industrial policy as only state intervention into the market, all four models was not able to explain fully different policy patterns in the respective industrial sectors. Acordingly, it is more relevant to consider industrial policy as conflict resolution among actors, existing in the state and market, who realize their interests respectively. In this context, one has to understand policy network patterns in the respective industrial sectors which emerge out of interactions among not only bureaucracy's industrial strategy but also business' strategy, cooperation and competition between business and bureaucracy, and poitician's intervention into the industrial sectors. In the managerial perspectives, not only life employment system, seniority system, corporate union system but also relational theory, technological development, production system were analyzed.
