하천에서 유량을 구하는 방법은 경험공식을 적용하는 방법과 직접 하천단면(流積)을 측정하고 그 단면에서 평균유속을 구하여 유량을 구하는 방법이 있다. 前者 방법의 적용은 공식을 적용하는 범위에 제한을 받는 단점이 있고, 後者의 방법은 비교적 정확한 유량을 구하는 것으로 많이 사용되고 있으나 문제점이 있어 그 문제점을 도출하고 개선하고자 한다. We have two methods to get the discharge of river : one is to apply empirical formula and the other is to measure the river section directly and take the mean velocity from it and get the discharge at last. The first method has a fault of limiting the scope of formula application, and the second method is used widely to get an exact discharge but has some problems too. In this study we have a purpose to find the problems and correct them.

This paper aims to intensify strategies for enhancing competitiveness of the agricultural wholesale markets to cope with pooling system currently increasing rapidly at producing areas in Korea. For this purpose, the impacts of joint marketing and pooling to agricultural marketing as a whole and agricultural wholesale markets are analysed after discussion on current situations of joint marketing and pooling of farm produce. It also analyses problems of the facilities, labor productivities, and laws and regulations of the agricultural wholesale markets. Based on these analyses, it suggests various development strategies for the agricultural wholesale markets to cope with changing marketing circumstances.

This study consists in clarifying the meaning of various angles and velocity, and two types of the stroke of a pushing shot and hitting shot through the three-dimensional image analyses among the factors of exercise. To attain the purpose of such studies, the result of experiment and analysis for each of three athletes of boys and girls in high school and three persons in general came to the conclusion as follows; 1. The last motion of a group of A having a command of a follow shot showed greatly, compared with two groups of B and C, and this showed that a group of A took a rectilinear motion greatly to gain power and two group of B and C took a rotary motion greatly to gain speed. 2. A group of A having a command of a pushing shot move body weight forward from behind and give the first consideration to a rectilinear motion, and two groups of B and C having a command of the stroke of hitting shot used the turning of the shoulder and the waist and gave much weight to a rotary motion than a rectilinear one. 3. The position of the hitting point of a group of A having a command of a pushing shot turned out to be the waist, and that of the hitting point of two groups of B and C, the chest, and namely this showed that the position of the hitting point was decided according to the form of the stroke and pictures of various kinds. 4. In impacting, the speed decreased, for the power was controled to keep an accurate timing of stroke just before impacting
알킬페놀 화합물의 HeLa cell (HL-60)의 세포독성에 대한 QSAR연구
김명길(Kim Myung-Gill),김재현(Kim Jae-Hyoun) 환경독성보건학회 2003 환경독성보건학회지 Vol.18 No.4
The purpose of the present study was to perform experiments of cytotoxicity using HeLa cell and to evaluate the possibility that QSAR is applicable 10 the cytotoxicity of alkylphenols. Higher toxicities were found in four alkylphenols in the following order: 4-n -Nonylphenol >4-tert-Octylphenol > 4-n-Octylphenol > 4-n-Heptylphenol. Whereas other alkylphenols were apparently less toxic. By using Percent Hydrophilic Surface Area (PHSA) quantitative structure-activity relationships (QSARs) models were developed: Cytotoxicity (%) = 90.14089-4.72224 PHSA (R²=0.2046, α=0.0265). It is concluded that some of the obtained data are useful to determine whether QSAR methods can be of general use in predicting that until further work is undertaken to develop QSARs for a much wider range of homologous series of alkylphenol compounds.
Bioassay Associated with Tau-fluvalinate Resistance in the Mite, Varroa destructor, from Korea

Varroa destructor is an ecto-parasite mite and worldwide pest of the honey bee Apis mellifera L. The pyrethroid tau-fluvalinate (Apistan), an acaricide that is tolerated by honey bees, has been used for varroa mite control since the mid 1980s. Even though various resistances to tau-fluvalinate in varroa mites have been reported from Europe, Israel, and USA, the nature of tau-fluvalinate resistance in varroa mites in Korea has never been investigated. To investigate and understand tau-fluvalinate resistance in varroa mites in Korea, we conducted bioassay in several apiaries located different regions in Korea. To understand the molecular mechanisms underlying the difference of tau-fluvalinate resistances in varroa mites, partial genomic DNA fragments of a voltage-sensitive sodium channel gene from varroa mites were cloned and sequenced, since tau-fluvalinate is known to act on the sodium channels directly. Two novel mutations in sodium channels of varroa mites were present in eight apiaries. Two mutations might be a geographical polymorphism of sodium channel of varroa mites in Korea.
Aglycone유도체의 구조활성에 의한 생물활성도의 예측
김명길,김재현 동덕여자대학교 2002 생활과학연구 Vol.7 No.-
This study investigated to predict the activities of biological endpoints for the aglycones such as daidzein, glycitein and genestein, using QSAR software (PASS program). Also, activities of biological endpoints were measured for aglycones, and the effects of addition of OH substituents on 9 different endpoints were analyzed using the same QSAR procedures. Position-specific effects according to certain substitution patterns by the addition of OH substituents on the ring moiety showed equivalent or slightly higher than that of the unsubstituted aglycones of biological endpoints with increasing number as well as certain substitution patterns of OH. However multi-substituted daidzein showed an carcinogen activity lower than that of the unsubstituted one.
ECT : CHILL96 언어를 위한 컬렉션 라이브러리

CHILL96은 통신 시스템 개발을 위한 표준 언어인 CHILL에 객체지향성과 재사용성을 위한 다양한 기능을 추가하여 확장한 것이다. 본 논문에서는 CHILL96 시스템을 위한 컬렉션 라이브러리 ECT의 개발에 관하여 소개하였다. ECT는 트리 구조의 모드 계층과 포괄적 프로시듀어로 구성되어 있다. ECT에서는 컬렉션을 위한 모드의 기능을 단순화시키는 한편 재사용이 쉬운 다양한 프로시듀어를 추가하였다. 그 결과 동일한 목적의 다른 라이브러리 시스템 보다 간단한 프로그래머 인터페이스를 가지면서도 유사한 기능성을 제공할 수 있었다. 컬렉션과 포괄적 프로시듀어는 열거자를 매개체로 서로 연관되며 이를 위하여 모든 컬렉션 모드는 열거자를 제공한다. 그러므로 부분적으로만 열거자를 제공하는 다른 라이브러리 시스템에 비해 포괄적 프로시듀어의 일반성이 매우 높다. CHILL96 is an extension of CHILL, the standard language for programming telecommunication systems, that incorporates advanced features for object-orientation and reusability. ECT, a collection library for CHILL96, is explained in this paper. ECT consists of a set of modes forming a tree-structured hierarchy, and also a set of generic procedures. The modes for collections of ECT provide minimal operations while additional functionalities are supplemented by a variety of highly reusable procedures. As a result, the resulting library provides functions quite comparable to other library systems of the same purpose do, but the programmer interlaces and implementations are much simpler. Collections and generic procedures are interrelated using iterators, and every collection mode provides an iterator in order to support this strategy. As a consequence, procedures of ECT are much more general than those of other library systems that provide iterators only for some selective modes.
