남선영,정연강,박경숙,김화자 韓國學校保健學會 1995 韓國學校保健學會誌 Vol.8 No.2

A survey has conducted on two hundred high school students of the first and second grade by way of questionnaine in Seoul. The purpose of this study on the information from the survey is to cstimate the level of awareness and probe how they feel and what they wish on sex. X2 inspection is designed to assess general aspects of responded contents by way of percentage and examine degree of satisfaction on previously experienced sex education and demand for sex cducation. The result is as follows. 1. As a result of the examination of degree of awareness on sex of respondents, 62% delines sex as human relationship including moral values for harmony between men and women. 64% of the men and 70% of the women say that sex is a natural thing. It comes to the conclusion that most of the respondent sgenerally consider sex positive. On chastity, 68.5% of the respondent answer that it means physical chastity, 12.5% that chastity before marriage should be kept, and 43% that it should be kept as far as possible. Most of them pespond that it should be kept. 2. As a result of the examination on the contents of sex, they answer they know well in the order of masturbation(72%), pregnancy(76%), and sex(63%). Contraception, abortion and ejection are contents they poorly informed of. 3. As a result of the examination on expericncdc of sex education, 83% of men and 100% of women have experienced sex, education, but their degreeof satisfaction to it is very low. And 49% of the whole is dissatisfactory to it. There is some difference between male and female students.(p=0.000) That result translatcs that fcmale studeuts are educated on sex tjhrough more systematic subjects than male ones. In addition, it turns out that teenagers get most information on sex through friends, seniors, and mass media such as vidcos, TV and radios. Correct and systematic sex education is need because wrong information on sex culd be taught and bring them to misbehave. 4. 87.5% of the respondents answer that sex education is necessary, so that degree of necessity for sex education, turns out to be very high. Also the main subject that should perform sex education is in the order of school(50%), Society(24.5), home(18.5%). They respond that most appropriated period for the beginning of sex education is about elementary school age(43%), and 34% believes it to be put ahcad of elementary school age. Anurse teacher accounts for 54% for the main subject that addresses sex education, to male students visit teachers are most favored for 50%. As a result of those, it could be concluded that most high school students want sex education from responsible persons who have systematic and professional knowledge on sex. 5. In order to perform proper sex education by the above results, better educational effects are obtained when characteristics and natures of teenagers are known and most wanted knowledge by them is taught in priority in times of planning sex education. Besides, the contents of sex education suitable for each school should be planned before elementary school age and sex education should be performed in accordance with students' demand. In addition, sex education should be attentively performed by home, all organizations of socicty as well as school. Therefore, sex education will play a great role in making teenagers reestablish their conception on sex when the traditional and moral value systems of our country and the new value systems which are being formed under the influcnce of the western culture are in harmony.

戰後 日本 社會科에 있어서 消費者敎育의 歷史的 變遷

남경희 서울敎育大學校 初等敎育硏究所 1997 한국초등교육 Vol.9 No.1

The objective of this study is to clarify the development of consumer education in social studies after the war in order to offer a viewpoint of consumer education in social studies. Consumer education in social studies was placed in a position thinking a life oriented economy from the consumer's standpoint in early years after the war. The number of comsumer problems was increased considerably with the growth of economy of about 1955. Under these circumstances, the position mentioned above has weakened reversely. It is in consequence of taking a serious view of systematic knowledge instead of experiental knowledge during this time period. In an upsurge of consumerism in the 1960's, the government began to pay attention to consumer education in order to deal with the increasing number of consumer problems. With a report of the National Welfare Council, consumer education was revived in social studies from 1965. Going forward, the concept of consumer protection was introduced into social studies from 1975. After that the National Welfare Council pursued the essence of consumer education reflecting the social changes and demands through a report of "Regarding Consumer Education in school"n 1986. Succeeding to an idea of this report, consumer image presented with A Course of Study In 1989 is consumer to the effect that judges independently and acts independently. Consumer education in japanese social studies, as seen above, emphasizes the learning from a view of consumer's independence in 1990's.

조남준,구자경 한국기술교육대학교 2001 論文集 Vol.8 No.1

The adsorptions of Thiobacillus ferrooxidans, Thiobacillus thiooxidans and their mixed cultures onto the copper-containing furnace dust were examined in an acidic medium solution. Adsorption of T. ferrooxidans and T. thiooxidans fits well to Langmuir isotherm. The maximum adsorption amount, XAm and adsorption equilibrium constant, KA gradually increase as the temperature increases from 5 ℃ to 35 ℃. The X_(Am) value of the mixed culture is larger than that of any single culture but slightly smaller than the sum of each bacterial component value, which indicates that these two bacteria have both of some preferential and competitive adsorption sites on furnace dust. The adsorption affinity, K_A of mixed culture is about 4.5 or 3.4 times larger than that of T. thiooxidans or T. ferrooxidans, respectively, which suggests that the synergistic effect exists in their bindings.

This study was designed to investigate the free amino acid compositions of salt-fermented fish products in the markets of Chonnam area. The results were as follows : The free amino acid compositions of salt-fermented fish products had varying figures according to the species of raw materials, that is, lysine and leucine were relatively abundant in Myul-chi jeot (salt-fermented anchovy), arginine inSae-woo jeot (salt-fermented small shrimp), glutamic acid inJa-oi jeot (salt-fermented small shrimp). lysine, arginine, alanine and phenylalanine in To-h jeot (salt-fermented trout), etc. Essential amino acid contents were contained 31.02%∼83.46% of total amino acids in all sample, and lysine and leucine were most abundant among essential amino acids. Especially tryptophan was the richest in Cham-jo-gae jeot, phenylalanine in To-ha jeot, Kal-chi-nae-jang jeot and Song-eo jeot in other essential amino acids. because the degree of protein degradation wouldl be influenced on fermentation periods, salt-concentration, fermentation temperature, etc, we expected more systemic research by some varied conditions and the developed analytical techniques on the salt-fermented fish products should be followed.

결정체 실리콘의 고유파장 센싱 능력

전경남 광주대학교 1996 産業技術硏究 Vol.7 No.-

재료를 투과하는 깊이가 빛의 파장에 따라 다르므로 센싱능력도 이에 따라 달라진다. 이 현상을 이용하여 실리콘으로 제작된 소자가 스펙트로미터와 같은 다중파장의 센싱에 응용될 수 있을지를 고찰해 보았다. 다중파장의 센싱에서의 문제점은 소자의 기하적인 형태와 설계에서만 유래되는 것이 아니고 실리콘 재료의 성질도 깊게 관여함을 이론적으로 밝혔다. 이상적인 소자의 방정식을 이용하여, 부적합 조건에서도 dc 광전류 데이터로부터 빛의 스펙트럼 정보를 얻어내기 위해서 해를 얻고자 하는 일련의 선형방정식이 심각한 부적합 조건속에 있음을 보였다. dc 대신 변조된 광전류 측정에서는 경계조건이 줄어들므로 보다 정확한 측정이 가능하여 파장의 분해능도 높아짐을 보여준다. The sensing capability is attributable to the wavelength dependence on the depth to which radiation penetrates the material. silicon devices can utilize With this phenomenon can utilze silicon devices in sensing multiple wavelengths for applications such as spectrometer. It is theoretically demonstrated that the problems in sensing multiple wavelengths may not be only due to limitations in the devices geometry and design, but also due to the fundamental material properties of silicon themselves. Using ideal device equations, it is shown that the set of linear equations that needs to solved to extract the spectral information of light from dc photocurrent data is severely ill-conditioned. It is also shown the modulated, instead of dc, photocurrent measurements may lead to smaller condition numbers, and therefore can be used for detection with better accuracy and wavelength resolution.

가스센서 신호에 대한 2단계 흡착과정 모델

전경남 광주대학교 1998 産業技術硏究 Vol.11 No.-

가스 센서를 이용한 가스농도 측정은 크게 두 단계의 과정으로 설명할 수 있다. 첫 번째 단계는 센서 표면에서 가스의 흡착과정이다. 두 번째 단계는 흡착된 가스분자에 의한 측정할 수 있는 센서 특성의 변화이다. 가스의 흡착은 가스 주변공간과 두 가지 단계 사이에서 가스분자가 가역적으로 흡착 및 탈착이 이루어지는 평형상태 프로세스로 설명할 수 있다. 이 모델의 주요 파라미터로는 제2 준위에서의 최대 빈자리 수, 초기에 존재하는 활동적인 특이점의 수이다. 특이점에 의해 흡착된 분자는 새로운 특이점으로 활동하거나 또는 기존의 특이점을 무력화시킬 수 있다. 측정값의 형성은 두 가지 상태에서 흡착된 분자의 합을 계산하는 것으로 설명할 수 있다. The measurement of gas concentrations with gas sensors can be described mainly by a two step process. The first step is the adsorption of gas at the sensor surface. The second step is the change of the measurable sensor quantity referring to the adsorbed gas molecules. The adsorption of gas can be described as an equilibrium process between the gas space and two states, in which the gas is reversibly adsorbed or desorbed. The main model parameters are the maximum number of places in the second state, the number of primarily existing active centers for the adsorption of the molecules are working as new centers or are covering existing centers, making them uneffective. The formation of the measured value can described as the calculation of the weighted sum of the adsorbed molecules in the two states.

산화아연 결정에서 표면현상에 대한 해석

전경남 광주대학교 1997 産業技術硏究 Vol.9 No.-

산화아연 결정에서 전계효과 이동도와 표면에서의 광도전율이 표면의 전자축적에 의해 크게 증가된다. 주입된 전자의 일부분만 전도대역에 남아있고, 대부분은 표면준위에서 트래핑 된다는 것이 이제까지의 설명이었다. 표면준위 트래핑 현상에 관하여 보상모델에서는 대역의구배가 변화하는 동안 벌크(bulk) 결함이 축적층 내부의 전하조건을 변화시키는 것으로 대체된다. 도전율의 온도 의존성과 Hall 효과로부터 벌크 결함준위를 계산하였다. 보상모델에 의한 공간전하층은 이전의 이론에 의한 추정보다 훨씬 얇게 나타났다. Surface photoconductivity and field effect mobility on zinc oxide crystals increase for several orders of magnitude with electron accumulation. Previous explanation was only a small fraction of the injected electrons appears in the conduction band whereas the main part is trapped by surface states. In the compensation model the trapping action of the surface states is replaced by that of bulk defects changing their charge condition within an accumulation layer during variations of band bending. From the temperature dependence of conductivty and Hall effect bulk defect levels are evaluated. As a result of compensation model space charge layers are much thinner than previously assumed.

국부적분 샘플링을 통한 데이터 수집과 프로세스 측정

전경남 광주대학교 1997 産業技術硏究 Vol.8 No.-

프로세스 측정에서 아날로그 센서 신호는 샘플링되어야 하고 디지털 프로세싱 전에 양자화 되어야 한다. 본 논문에서는 신호의 국부적분을 통하여 얻는 대체 샘플링 방법을 소개한다. 이 방법은 신호를 제대로 잘 표현해 주며, 스파이크나 잡음 또는 다른 방해에 대하여 비교적 민감하지 않다. In process measuring, analog sensor signals must be sampled and quantized prior to digital processing. Am alternative sampling method, in which the samples are obtained by local integration of the signal, is presented in this paper. This method offers a good representation of the signal, and is relatively insensitive to spike or noise and other disturbances.
