  • This study was carried out to investigate in influence of inoculation B. sp. and lime types on nutrient content of peanut seed, and the correlation between nutritient contents in seed and plant. 1. Inoculated B. sp., content of crude protein, phenylalanine, isoleucine, cystine, histidine, aspartic acid, serine, and alanine in seed were increased significantly, but that of crude fat was decreased. 2. The content of crude fat was the highest without lime, glutamic acid was the highest with calcium sulfate, valine, phenylalanine, isoleucine, leucine, lysine, aspartic acid, serine, glycine and alanine with slaked lime, and histidine with calcium carbonate. 3. The content of crude protein in seed was negatively correlated with that of crude fat. The contents of chlorophyll, allantoin, ammonia, free amino acid, T-N, $P_2O_5$, and CaO in leaf at 100 days after sowing were positively correlated with the content of crude protein and various kinds of amino acid in seed, but negatively with the content of crude fat. The content of nitrate in leaf at 100 days after sowing showed the result of contrary tendency.

  • 불어의 "묵음 e(e muet)"에 대한 정의를 내리기는 매우 까다롭다. 불어에서 "e"가 "묵음 e(e muet)"로 불리우는 이유는 "e"가 흔히 탈락되기 때문이다. 현재 "e muet"는 다음 발화체에서 볼 수 있듯이 열린음절에서만 나타난다. "Je/le/re/de/man/de/ce/re/por/ta/ge/." [omitted](나는 그 리포트를 다시 요구한다. : 이 경우 실제 발화시 schwa 삭제 규칙이 적용된다.) 둘째, 접두사에 나타나는 "e muet"는 s의 중자음 앞에서 s가 유성음, [z]로 발음되는 것을 막기 위해 쓰인다. "ressembler[omitted](닮다); ressentir[omitted](느끼다)" 같은 경우, 셋째, 몇몇 낱말의 경우 고어의 철자가 약화되어 "e muet"로 발음이 되고 있다. "monsieur[$m{\partial}sj{\emptyset}$](미스터), faisan[$f{\partial}z{\tilde{a}}$](꿩), faisait[$f{\partial}z{\varepsilon}$]("하다"동사의 3인칭 단수 반과거형)"등. 또 과거 문법학자들은 이를 "여성형의 E"로 불렀는데, 이는 형태론적으로 낱말의 여성형을 남성형과 구분짓기 위해 사용되고 있기 때문이기도 하다. 예를 들어, "$aim{\acute{e}}-aim{\acute{e}}e$"(발음은 둘 다 [${\varepsilon}me$]로 동일하다 : 사랑받다)의 경우. 현대불어의 구어체어서 "e muet"는 어말자음을 발음하기 위해 쓰이고 있다. 예를 들어, "pote[pot](단짝)-pot[po](항아리)". 이러한 "e muet"는 발음상으로 지역적, 개인적 및 문맥적 상황에 따라 그 음색 자체가 매우 불안정하며 여러 가지 음가(열린 ${\ae}$ 또는 닫힌 ${\O}$)로 나타난다. 예를 들어 "seul[$s{\ae}l$](홀로), ceux[$s{\O}$](이것들)"에서와 같이 발음되며, 또한 원칙적으로 schwa, [${\partial}$]로 발음이 되는 "Je[$\Im\partial$]"와 "le[$l{\partial}$]"의 경우, Paris 지역에서는 "Je sais[${\Im}{\ae}{\;}s{\Im}$](나는 안다); Prends-le[$pr{\tilde{a}}{\;}l{\ae}$](그것을 집어라)"로 발음을 하는 한편, 프랑스 북부 지방세서는 동일한 발화체를 [${\ae}$]대신에 [${\o}$]로 발음한다. 실제로 언어학적 측면에서 고려되는 "e muet"는 schwa로 나타나는 "Je[$\Im\partial$]"와 "le[$l{\partial}$]"의 경우인데, 불어 음운론에서는 schwa에 의해 대립되는 낱말짝이 없기 때문에 schwa를 음소로 인정할 것인가에 대해 논란이 있다. 그러나 불어에서 schwark 음운론적 역할을 한다는 사실은 다음과 같은 예에서 찾아 볼 수 있다. 첫째, 발음상으로 동사의 변화형에서 "porte[$p{\jmath}rte$](들다: 현재형), porte[$p{\jmath}rte$](과거분사형), porta[$p{\jmath}rte$](단순과거형)"등이 대립되며, 이휘 "Porto[$p{\jmath}rte$](포르토)"와도 대립된다. 둘째, 어휘적 대립 "le haut[$l{\partial}o$](위)/l'eau[lo](물)"와 형태론적 대립 "le[$l{\partial}$](정관사, 남성단수)/les[le](정관사, 복수)"등에서 "묵음 e"는 분명히 음운론적 역할을 하고 있다. 본 논문에서는 이와 같이 음색이 복잡하게 나타나는 "e muet"의 문제를 리듬단위, 문맥적 분포 및 음절모형 측면, 즉 음성학 및 음운론적 측면에서 다양하게 분석하여 그 본질을 규명해 보고 "e muet"탈락현상을 TCG(Theorie de Charme et de Gouvernement) 측면에서 새롭게 해석해 보았다.

  • We examined the hepatitis G virus infections among 227 Koreans who were healthy or were suspected of hepatitis and determined the phylogenetic relationship based on a part of the NS-5 region of 5 positive samples. Viral RNA was extracted from sera and cDNA was synthesized and subsequently amplified by RT-PCR (reverse transcription-polymerase chain reaction) or RT-nested PCR using random hexamer and NS-5 specific primers (470-20-1-77F, 470-20-1-211R, HGVNESTFO, HGVNESTRE). Five positives were found to belong to samples of patients showing symptoms of viral hepatitis. Primers used for PCR or nested PCR were derived from the NS-5 region. On the other hand, no amplification was detected using primers derived from the 5'-NCR (G-146F, G-401R). We performed TA cloning and sequencing of 5 amplified fragments, and their sequences were compared with those of foreign isolates of HGV. The phylogenetic analysis using MegAlign programme of DNAstar has shown that the Korean isolates are clustered on the phylogenetic tree. In summary, we confirmed the hepatitis G virus infection in 5 cases out of 12 patients showing the symptoms of viral hepatitis. The phylogenetic analysis of sequences of 5 amplified fragments showed that their relations to each other were closer than those to the foreign HGV isolates reported.

  • Surface membrane proteins of virulent RH strain and tissue cyst-forming Fukaya strain of Toxoplasma gondii were analysed by SDS-polyacrylamide gel electrophoresis after LPO-catalyzed surface iodination and lectin blotting, then identified the zoite-specific antigens. Prior to the analyses, purification of RH tachyzoites from mouse peritoneal exudate and of Fukaya bradyzoites from mouse brain tissues were performed by centrifugation - on the discontinuous Percoll density-gradient. Ta- chysoites were obtained at the interface of 50U and 60% Percoll solution and brain cysts were harvested at the interfaces of 40-50% and 50-60%, then bradyzoites were obtained by treating the cysts with hypertonic solution. The LPO-catalyzed iodination detected 15 KDa and 14 KDa proteins o( brady- zoites and 30 KDa protein of tachysoites as major bands with several other minor bands. But Con A blotting revealed some bands of 200 K∼50 KDa glycoproteins of bradyzoites and 52 KDa band as major and minor bands of 33 K∼20 KDa of tachyzoites. Phytohemagglutinin did not detect any band in the two forms. EITB with anti- Fukaya antibody and anti-RH antibody revealed cross-reactivities between the two forms. Despite the cross-reactivity, anti-Fukaya antibody reacted with 15 KDa band of bradyzoites specifically and, anti-RH antibody with 52 KDa, 30 KDa, and 25 KDa bands of tachyzoites, respectively. It was identified that 15 KDa protein in bradyzoite, which was not a glycoprotein, was a major membrane protein with sufficient antigenicity, and in the case of tacky- zoite, 52 KDa surface glycoprotein (gp52) with specific antigenicity might be added to the major surface protein, p30.

  • In this paper, we propose an efficient face region detection technique for the content-based video summarization. To segment video, shot changes are detected from a video sequence and key frames are selected from the shots. We select one frame that has the least difference between neighboring frames in each shot. The proposed face detection algorithm detects face region from selected key frames. And then, we provide user with summarized frames included face region that has an important meaning in dramas or movies. Using Bayes classification rule and statistical characteristic of the skin pixels, face regions are detected in the frames. After skin detection, we adopt the projection method to segment an image(frame) into face region and non-face region. The segmented regions are candidates of the face object and they include many false detected regions. So, we design a classifier to minimize false lesion using CART. From SGLD matrices, we extract the textual feature values such as Inertial, Inverse Difference, and Correlation. As a result of our experiment, proposed face detection algorithm shows a good performance for the key frames with a complex and variant background. And our system provides key frames included the face region for user as video summarized information.

  • We observed DNA damages as a function of mean absorbed dose to identify the indirect effect of high-energy radiation such as x-ray. Monolayer films of lyophilized pGEM-3Zf(-) plasmid DNA deposited on tantalum foils were exposed to Al $K{\alpha}$ X-ray (1.5 keV) for 0, 3, 7 and 10 min, respectively, in a condition of ultrahigh vacuum state. We compared DNA damages by X-ray irradiation with those by 3 eV electron irradiation. X-ray photons produced low-energy electrons (mainly below 20 eV) from the tantalum foils and DNA damage was induced chiefly by these electrons. For electron beam irradiation, DNA damage was directly caused by 3 eV electrons. Irradiated DNA was analyzed by agarose gel electrophoresis and quantified by ImagaQuant program. The quantities of remained supercoiled DNA after irradiation were linearly decreased as a function of mean absorbed dose. On the other hand, the yields of nicked circular (single strand break, SSB) and interduplex crosslinked form 1 DNA were linearly increased as a function of mean absorbed dose. From this study, it was confirmed that DNA damage was also induced by low energy electrons ($0{\sim}10\;eV$) even below threshold energies for the ionization of DNA.

  • In construction site, there are some occasions where concrete under initial curing is being affected by nitration from nearby vibration sources. To study these effects, in this paper, strength characteristics of concrete specimens subjected to continuous vibration up to 12 hours in vertical direction after concrete placement were observed. And through the vibration time control experiment where a number of time combinations consisted of times before and after applying vibration during initial curing period were used as experimental parameters, possibility of concrete strength improvement was investigated. From the experimental results, it could be seen that the concrete strengths were mostly decreased due to the increase of vibration velocity during initial curing period. But fluctuation ratio of concrete strength did not have any close correlations with the vibration times. And results of vibration time control experiment showed that if times before applying vibration sustains at least more than 3 hours, subsequent vibrations after that hours do not affect the concrete strength in any unfavorable ways.

  • This study was conducted to correlate the quality depending upon sensory evaluation of ESL(extended shelf life) and non-ESL milk during the shelf life. The most important quality assurance is sensory evaluation for dairy products. ESL and non-ESL milk were stored at $5^{\circ}C$ and $10^{\circ}C$ for 14 days. In order to compare physicochemical and sensory properties, pH, TA(titratable acidity), protein, fat, lactose, FFA(free fatty acid), and other organoleptic characteristics were measured. The results showed that physicochemical properties were not significantly changed during storage. On the other hand, the freshness was affected by storage conditions. The most freshness depending upon sensory evaluation was monitored at 5 days storage. Descriptive and acceptability analysis showed that more acceptable milk was ESL milk than non-ESL milk because of off-flavor and after taste of non-ESL milk. According to these results, it was shown that the freshness of milk products depends on sensory. And ESL milk was fresher than non-ESL milk after storage.

  • Two medium-leaf ecotypes (CY6069, CY6097) belonging to one species (Zoysia japonica) of Korean lawngrasses were selected in sod production fields in Jang Seong, Korea. They were reported to have distinct morphological and growth rate characteristics different from the preferred medium-leaf type zoysiagrass in Korea. This study was conducted to define further the genotypic difference at the molecular level and to develop DNA marker based on the specific DNA fragment. Polymorphic DNA fragments were first explored by using randomly amplified polymorphic DNA (RAPD) primers, which were then converted into PCR-based sequence characterized amplified region (SCAR) markers. The CY6069-specific primer set amplified about 550 bp successfully, while the CY6097 marker produced the expected 690 bp band, by which those markers were nominated by CY6069_550 and CY6069_690 SCARs, respectively. Together with the reported morphological and other phenotypic features, the SCAR markers confirmed in this study will be useful to identify those medium-leaf zoysiagrass genotypes when they are cultivated with other vegetatively propagated warm-season turfgrasses in sod farms.
