尹聖重,黃鍾奎 韓國作物學會 1986 Korean journal of crop science Vol.31 No.2

우리나라의 재래종 대화형 대두인 부채콩의 생육 및 형태적 특성을 정상형 대두인 단엽콩과 비교하였던 바 그 결과를 요약하면 다음과 같았다. 1. 대화형 대두인 부채콩의 주경은 생육이 진행됨에 따라 대화가 심해졌고 정상형인 단엽콩에 비해 출엽이 불규칙하였으며 주경엽수는 단엽콩보다 훨씬 증가하였으나 총엽수는 크게 다르지 않았다. 2. 부채중의 주경대화정도는 약 3.1정도였으며 대화정도는 정상형인 단엽콩의 주경과 분핵의 생육량과 유관하였다. 3. 부채콩의 분지수는 단엽콩보다 적었으나 분지가 대화하는 경우도 있었으며 엽병의 대화도 관찰되었다. 4. 부채콩은 협의 대부분이 주경 선단부에 집중 분포하였다. 5. 부채콩의 수량은 단엽콩의 60%정도였으며 수량감소의 주원인은 종실중과 협당입수의 감소였다. 6. 주경 횡단면의 유관속수는 부채콩이 많았으나 각 유관속은 단엽콩이 발달하였다. This experiment was carried out to obtain some information about the growth habit and morphological and anatomical characteristics of fasciated soybean, var. Buchai-kong. The results obtained are summarized as follows: 1. Main stern of fasciated soybean, var. Buchai-kong was gradually broadened and became flat, on which leaves emerged irregularly compared with normal soybean, var. Danyeop-kong. The number of leaves on main stern was more in Buchai-kong, but the total number of leaves per plant was not considerably different each other. 2. The degree of fasciation (max./min. in diameter at the broadened part) in main stern of Buchai-kong was about 3.1, and was related to the amount of growth of main stern and branches of Danyeop-kong. Stern fasciation types found in Buchai-kong were linear (the most common) and bifurcated with regard to branching of main stern tip. 3. The number of branches per plant was much less in Buchai-kong than in Danyeop-kong. There were fas-ciated branches and fasciated petiole in Buchai-kong. 4. About 75 percent of pods of Buchai-kong were concentrated on the top of stern, which showed strong pod clustering. 5. Seed yield per plant of Buchai-kong was about 60 percent of that of Danyeop-kong, and the decrease in seed yield was mostly affected by the decrease in seed weight and seeds per pod. 6. The number of vascular bundles of transection of mature stern was more in Buchai-kong, but Danyeop-kong developed the better vascular bundle.

The purpose of this paper is development of the most suitable backfill material which increases thermal stability and decreases thermal resistances for increasing capacity of the transmission of electricity. In order to proceed this study, the sand which recently was used as backfill material and the stone dust as single material for most suitable backfill material was chosen and experiments on thermal character and basic soil properties were proceeded for appreciating stability and economical efficiency. As a result of this study, natural moisture content of stone dust was higher than that of sand and porosity of stone dust and thermal resistance of stone dust was lower than that of sand. Then the stone dust are expected to increase capacity of the transmission of electricity. In point of stability, because total strain of pipe was within allowed strain, two materials are expected to ensure against risks. Stone dust is considered as useful backfill materials by contributing great economical efficiency, because a price of stone dust is half to the sand.

A cDNA encoding γ-tocopherol methyltransferase (γ-TMT) from Arabidopsis thaliana was overexpressed in lettuce (Latuca sativa L.) to improve the tocopherol composition. Seven lines of lettuce (T0) containing the γ-TMT transgene were produced by Agrobacteriummediated transformation. The inheritance and expression of the transgene were confirmed by DNA and RNA gel blot analyses as well as quantification of tocopherols and γ-TMT activities. The ratio of α-/γ- tocopherol content (TR) varied from 0.6 to 1.2 in nontransformed plants, while the T0 plants had ratios of 0.8 to 320. The ratio ranged from 0.4 to 544 in 41 T1 progenies of the T0 transgenic line gTM3, and the phenotypic segregation indicated monogenic inheritance of the transgene (i.e., 3:1 = dominant:wild-type classes). There was a tight relationship between the TR phenotype and γ-TMT activity, and enzyme activities were affected by the copy number and transcript levels of the transgene. The TR phenotype was stably expressed in T2 progenies of T1 plants. The results from this study indicated that a stable inheritance and expression of Arabidopsis γ-TMT transgene in lettuce results in a higher enzyme activity and the conversion of the γ-tocopherol pool to α-tocopherol in transgenic lettuce.

윤성중,김건웅,Yoon, Sung-Jung,Kim, Geon-Ung 한국정보통신학회 2006 한국정보통신학회논문지 Vol.10 No.3

보안 키 관리 기능은 망 보안을 위 한 필수 요소 중 하나로서, IPSec, HIP 등 다양한 프로토콜에서 이러한 기능을 요구하고 있다. 망 계층에서 보안 키 관리 기능을 제공하기 위한 두가지 방안이 있는데, 그것들은 디렉토리 서비스를 이용하는 것과 DNS 서비스를 이용하는 것이다. 본 논문은 디렉토리 서비스를 이용하여 보안 키 관리 시스템을 구현한 예를 소개한다. 디렉토리 서비스(OpenLDAP)와 공개키 알고리즘(FLINT/C), IPSec(FreeS/WAN)의 기능들을 공개 소프트웨어들을 이용하여 구축하였으며, 보안 키 관리 시스템을 이용한 암호화된 메시지 교환, IKE 데몬과의 연동을 통해 구현된 관리 시스템의 기능을 확인하였다. The security key management function is a key element to secure network environment, and many protocols include IPSec, HIP, etc. demand this function. There are two solutions to provide the key management function in the network layer, one is a method for storing security key material in the directory, and the other is a method for storing security key material in DNS. In this paper we present an implementation of key management system by LDAP. We deployed the open source solutions for directory service(OpenLDAP), cryptographic algorithm (FLINT/C), IPSec(FreeS/WAN), and verified the key management system by the encrypted message exchange and the interoperability test by un daemon.

혐기 또는 저온처리에 따른 보리 유식물체내 유리아미노산 및 유리산 함량의 변화

尹聖重,柳南熙 韓國作物學會 1996 Korean journal of crop science Vol.41 No.2

발아후 일주일간 생육한 보리 유식물체를 이용하여 혐기처리, 저온처리 및 기계적 상처에 대한 보리 식물체의 반응양상을 유리아미노산과 유리당 함량의 변화를 분석하여 조사하였다. 혐기적처리에 반응하여 함량의 변화가 뚜렸하게 나타나는 아미노산은 alanine, GABA, glutamic acid였다. Alanlne과 GABA함량은 10시간까지의 혐기처리에 의해 급속히 증가하였으나 glutamic acid 함량은 크게 감소하는 경향을 나타내었다. 상처에 의한 alanine, GABA, glutamic acid반응 양상은 혐기처리와 유사하였으나, 함량변화 정도는 혐기처리에서 보다 훨씬 낮았다. 저온처리에 의하여 지상부와 뿌리 중의 GABA 함량이 증가하였다. 혐기적 처리에 의하여 지상부의 유리당함량이 변화하였으며, glucose나 fructose보다는 sucrose의 함량변화가 상대적으로 크게 나타났다 Effects of anaerobic, mechenical wounding and cold treatments on free amino acid and free sugar contents were examined in 7 day-old barley seedlings. In barley shoots under anaerobic condition, drastic changes in free amino acid content were observed. Alanine, ~gamma -aminobutyric aicd(GABA) and glutamic acid contents changed most prominantly. Alanine and GABA contents increased rapidly with incubation time up to 10 hr. Glutamic acid content, however, decreased drastically during the first 5 hr of incubation, then increased thereafter. Barley shoots showed similar but smaller changes in amino aicd contents in response to mechanical wounding. GABA content increased in shoots and roots in response to the cold treatment. But increase in GABA content was greater in anaerobic than cold treatment. In anaerobically treated shoots, changes in free sugar content were less prominant than those in amino acid content. Sucrose content changed relatively larger than glucose and fructose contents in excised shoots.

Objective : This study was done to clarify ambiguous non-standard weight and measuring units in medical classics. Methods : Using medical classics and research dissertations, we studied the basic definitions of weight and measuring units and the types of non-standard weight and measuring units. We compared non-standard weight and measuring units in the reference literatures, to determine the dose of herbs in the prescriptions. Results : There are three types of units in non-standard weight and measuring units. These are 'Quantity measuring unit', 'Resembrance measuring unit', and 'Eye measuring unit'. And we found historical efforts and progresses for proper ways to convert non-standard weight and measuring units to standard weight and measuring units. Conclusions : This research will be the basic data for the standardization of prescriptions. Additional study was still required for precise weighing and measuring in Korean medicine and pharmacy.
