The purpose of this study is to provide the basic data in order to develop of some educational programs for increasing breast feeding by studying the female university student's knowledge and attitude on breast feeding, who will become a mother in future. The respondents of this research were selected at random for 462 female students at the university in Seoul and Kyongki area, and it was the period collected the data from Oct 28, 2000 to Nov 8, 2000. The method of study distributed the measuring tools of knowledge with 33 items and the tools of measurement with 20 items on the attitude of breast feeding to the respondents directly, and collected them. The data were analyzed to use SPSS program. Unpaired t-test, ANOVA, Pearson correlation coefficient and Multiple regression analysis were used for the calculation of difference between groups and the results were as follows ; 1. The breast feeding was 50.6% in the period of lactation for the respondents and the nuclear families were 81.7% in family constituent unit. In the future the wisher of breast feeding was 91.5%, the medical personnel was a major informer who enjoyed their best confidence, Besides the respond-ents responded that the proper period for education of the breast feeding was in a high school. 2. The level of Knowledge on breast feeding. The respondents's knowledge on breast feeding was average $16.40{\pm}4.59$ points on the basis of 33 points and On the merits and demerits ratio of breast feeding has shown highest but there was low in the field of such a concrete and practical plan as the estimate of breast feeding and the method and mindfulness for breast feeding. The higher grader, the college of the natural science showed significantly the higher points in the knowledge degree by respondents's characters and in such cases the persons of breast feeding or the informed of breast feeding by a medical personnel or the women of strong will for breast feeding action in the future. 3. The Attitude on breast feeding. There was relatively shown a positive attitude of the total average $60.50{\pm}7.59$ points and the average evaluation $3.04{\pm}.36$ points in the attitude on breast feeding. The attitude by each factors has the highest points in the practical action aspect but the lowest in the emotional aspect. The attitude on breast feeding by respondents's characters significantly showed a positive attitude in such cases the persons of breast feeding or the informed of breast feeding or the women of strong will for breast feeding action in the future. 4. Relation to knowledge and attitude on breast feeding. There was shown a correlation of definition in the relation to knowledge and attitude on breast feeding, 5.Factors which have an effect on knowledge and attitude on breast feeding. The factors which have an effect on knowledge of breast feeding were attitudes on breast feeding, graders, the college of natural science and the informed of breast feeding. Also the factors which have an effect on attitude on breast feeding were on will and knowledge on breast feeding, a large family, the informed of breast feeding. In conclusion, it will have to enforce a systematic education on the method of a practical breast feeding enlarged by a medical personnel and professional early enough as the information provision on breast feeding enables one to increase knowledge and attitude on it, besides it has relations with their practical will.

This study was a part of large scale of a prospective study on attitudes of professional students in medicine, nursing and teaching toward population related issues in Korea. The study was first conducted in May 1974 and then in May 1975 for the 1974 class cohot using a questionaire consisted of attitude scales and other items developed by Lee. The purpose of stuay was twohold, namely, to determine the difference in students among specializations on one hand and between the first and second years in the 1974 class cohot regarding tile subject matter. A one-way analysis of variance was used for attitude scale, and absolute and relative frequency were computed for the analysis of non-attitude scale items by employing Fishers' Ratio and Duncan's multiple range test at 5% level and chi square test at 5% level as significance tests. The hypothesis 'students in health profession are more likely to have positive attitudes toward population related issues progressively as class year advances than students in teaching profession' was tested and the following results were obtained: 1) Nursing students were more likely to display favarable attitudes toward family planning than medical or teaching students although the class cohot showed slightly negative improvement in the second year. Medical and teaching students apperaed to have slightly improved attitudes in the second year. 2) Respondents in general perceived national family planning program as a means of population control and this tendency was more true among nursing students as the class year advances than two other professional groups of students. Students in teaching profession appeared to perceive it more as a means to improve individual family welfare while health students were likely to see as to improve maternal and child health. This tendency was progressively improved as the class year advanced. 3) The majority of students regardless of their respective specializations believed that family planning program should be directed toward the improvement of individual family welfare. No progressive changes in the class cohot were observed. 4) About the plan to use contraceptives in future, no singnificant differences were observes among different specializations nor in different class years. However, the majority was confirmed to have a plan to use contracepives in future. An increasing proportion of the undecided category was observed, as class year advanced among health students. 5) Students in health profession were found to be more favorable about 'more leisure opportunities' as motive for limiting number of children whereas education students indicated the reasons as 'facilitate ambitions' and 'economic base' The progressive changes toward positive direction in both groups were observed as the class years advanced. 6) Attitudes toward induced abortions of the health students were observed to be positively related to class years while an inverse relationship was found in teaching students who showed much less favor in the subject matter than health students. This phenomenon may be due to the different exposure to learning environments unique to respective specializations. 7) Health students were found to have more favorable attitudes toward population education in general than the teaching students. The teaching students appeared to have changed more to the negative direction when they became the second year while no such development was observed in health students. The teaching students seemed to hold a very conservative position with regard to sex education in schools. 8) About the equality of sexes, the nursing group was found to be most favorable while the reverse was true in the teaching group. A change in the negative direction as the class year advanced was found in the teaching group. 9) About questions related to fertility values-the 10 percent of respondents regardless of specialization indicated that they would maintain their single status in future, however no change was observed in the second year. The desired number of children was found to be two by the majority of students in nursing, medicine and teaching in order of high proportion. No changes in a different class year were observed. The childless marriage was seen by nursing students as a problem more than other students, but a slight change in positive direction was found when the nursing students became the second year. In summing, as data supported in the above, students in health profession demonstrated more favorable attitudes toward population related issues than the teaching students and this tendency became more apparent in the second year. It was noticed that health students were more conscious about the health aspect of population and family planning program while the teaching students gave more attention to the socioeconomic aspect. The sex variable seemed to have operated in the item related to the equality of sexes. In conclusion, as data presented in the above, the hypothesis of this study was accepted except in the few items. It should be noted that the limitation of this study is the short duration of the observation in measuring the possible attitude changes. It should include curriculum analysis for the respective specializations in order to indentify the area of curriculum impact on students in future study.

일본의 제3기 퇴적분지 내 분포하는 주요 벤토나이트 광상인 Myogi, Tsukinuno, Dobuyama 및 Kawasaki 광상의 산상과 성인을 비교하였으며, 각 광상에서 산출되는 대표적 벤토나이트를 대상하여 광물학적 특성 및 물리화학적 특성이 비교되었다. 일본에서 산출되는 벤토나이트 광상은 신생대 제3기 마이오세기～플라이오세기에 형성된 녹색응회암대 내에 주로 분포한다. Myogi, Tsukinuno 및 Kawasaki 광상은 속성변질작용에 의해, Dobuyama 광상은 열수변질작용에 의해 형성 되었다. 속성변질광상인 Myogi, Tsukinuno 및 Kawasaki 광상은 층상형 또는 성층형 광체형을 보이나 열수변질광상인 Dobuyama 광상은 콘형의 광체형을 나타낸다. 이 광상들의 형성 시기는 1.8～21 Ma까지 넓은 년대 범위를 보이나 대체로 초기～중기 마이오세기에 형성되었다. 몬모릴로나이트 함량비가 가장 높은 Dobuyama 광석이 높은 표면적, CEC, MB 흡착량 및 강도 값을 보인다 몬모릴로나이트 함량비도 다소 높고 Na-형인 Tsukinuno 광석은 강 알카리성, 높은 점도 및 팽윤도를 보인다. Na-Ca 혼합형인 Kawasaki 광석들은 Na-형에 비해서는 낮은 점도와 팽윤도를 보이나 Ca-형인 Dobuyama 보다는 다소 높다. 제올라이트 함량비가 높은 Myogi 광석은 Na-형이나 몬모릴로나이트 함량비가 가장 낮기 때문에 낮은 점도, MB 흡착량, 강도값을 나타내나 CEC와 표면적 값은 다소 높다. 이는 제올라이트의 영향으로 생각된다. 대체적으로 수용액계에서 Na-형은 강한 분산이 초래되나 Ca-형은 응집이 보다 강하게 일어나며, 두 유형 모두 매우 서서히 응집이 초래되었다. 벤토나이트의 물성은 몬모릴로나이트의 함량, 층간 양이온종이나 불순광물(특히 제올라이트)에 의해 주로 규제되는 시료도 있지만, 몇 시료는 이와 일치되지 않는다. 이는 이 연구에서 확인치 못한 몬모릴로나이트의 층전하 간과 같은 결정-화학적 및 몬모릴로나이트의 형상비와 같은 결정 형태적 특성에 의한 영향일 것으로 해석 된다.

Fully sealed field emission display in size of 4.5 inch has been fabricated using single-wall carbon nanotubes-organic vehicle com-posite. The fabricated display were fully scalable at low temperature below 415$^{\circ}C$ and CNTs were vertically aligned using paste squeeze and surface rubbing techniques. The turn-on fields of 1V/${\mu}{\textrm}{m}$ and field emis-sion current of 1.5mA at 3V/${\mu}{\textrm}{m}$ (J=90${\mu}{\textrm}{m}$/$\textrm{cm}^2$)were observed. Brightness of 1800cd/$m^2$ at 3.7V/${\mu}{\textrm}{m}$ was observed on the entire area of 4.5-inch panel from the green phosphor-ITO glass. The fluctuation of the current was found to be about 7% over a 4.5-inch cath-ode area. This reliable result enables us to produce large area full-color flat panel dis-play in the near future. Carbon nanotubes (CNTs) have attracted much attention because of their unique elec-trical properties and their potential applica-tions [1, 2]. Large aspect ratio of CNTs together with high chemical stability. ther-mal conductivity, and high mechanical strength are advantageous for applications to the field emitter [3]. Several results have been reported on the field emissions from multi-walled nanotubes (MWNTs) and single-walled nanotubes (SWNTs) grown from arc discharge [4, 5]. De Heer et al. have reported the field emission from nan-otubes aligned by the suspension-filtering method. This approach is too difficult to be fully adopted in integration process. Recently, there have been efforts to make applications to field emission devices using nanotubes. Saito et al. demonstrated a car-bon nanotube-based lamp, which was oper-ated at high voltage (10KV) [8]. Aproto-type diode structure was tested by the size of 100mm $\times$ 10mm in vacuum chamber [9]. the difficulties arise from the arrangement of vertically aligned nanotubes after the growth. Recently vertically aligned carbon nanotubes have been synthesized using plasma-enhanced chemical vapor deposition(CVD) [6, 7]. Yet, control of a large area synthesis is still not easily accessible with such approaches. Here we report integra-tion processes of fully sealed 4.5-inch CNT-field emission displays (FEDs). Low turn-on voltage with high brightness, and stabili-ty clearly demonstrate the potential applica-bility of carbon nanotubes to full color dis-plays in near future. For flat panel display in a large area, car-bon nanotubes-based field emitters were fabricated by using nanotubes-organic vehi-cles. The purified SWNTs, which were syn-thesized by dc arc discharge, were dispersed in iso propyl alcohol, and then mixed with on organic binder. The paste of well-dis-persed carbon nanotubes was squeezed onto the metal-patterned sodalime glass throuhg the metal mesh of 20${\mu}{\textrm}{m}$ in size and subse-quently heat-treated in order to remove the organic binder. The insulating spacers in thickness of 200${\mu}{\textrm}{m}$ are inserted between the lower and upper glasses. The Y\ulcornerO\ulcornerS:Eu, ZnS:Cu, Al, and ZnS:Ag, Cl, phosphors are electrically deposited on the upper glass for red, green, and blue colors, respectively. The typical sizes of each phosphor are 2~3 micron. The assembled structure was sealed in an atmosphere of highly purified Ar gas by means of a glass frit. The display plate was evacuated down to the pressure level of 1$\times$10\ulcorner Torr. Three non-evaporable getters of Ti-Zr-V-Fe were activated during the final heat-exhausting procedure. Finally, the active area of 4.5-inch panel with fully sealed carbon nanotubes was pro-duced. Emission currents were character-ized by the DC-mode and pulse-modulating mode at the voltage up to 800 volts. The brightness of field emission was measured by the Luminance calorimeter (BM-7, Topcon).

The task network which is formed of different individuals can be recognized as a social network. Therefore, the way to communicate with people inside or outside the network has considerable influence on their outcome. Moreover, the position on which a member stands in a network shows the different effects of the information systems supporting communication with others. In this paper, it is to be studied how personal CMC (computer-mediated communication) tools affect the mission that those who work for a network perform through diverse task networks. Especially, we focused on synchronicity of CMC. On this score, the perspective of Media Synchronicity Theory was taken that had been suggested by criticizing Media Richness Theory. It is the objective, from this perspective, to find which characteristics of networks make the value of IT supporting synchronicity high. In the research trends of social networks, there have been two traditional perspectives to explain the effect of network: embeddedness and diversity ones. These differ from the aspect which type of social network can provide much more economic benefits. As similar studies have been reported by various researchers, these are also divided into the bonding and bridging views which are based on internal and external tie, respectively, Size, density, and centrality were measured as the characteristics of personal task networks. Size means the level of relationship between members. It is the total number of other colleagues who work with a specific member for a certain project. It means, the larger the size of task network, the more the number of coworkers who interact each other through the job. Density is the ratio of the number of relationships arranged actually to the total number of available ones. In an ego-centered network, it is defined as the ratio of the number of relationship made really to the total number of possible ones between members who are actually involved each other. The higher the level of density, the larger the number of projects on which the members collaborate. Centrality means that his/her position is on the exact center of whole network. There are several methods to measure it. In this research, betweenness centrality was adopted among them. It is measured by the position on which one member stands between others in a network. The determinant to raise its level is the shortest geodesic that represents the shortest distance between members. Centrality also indicates the level of role as a broker among others. To verify the hypotheses, we interviewed and surveyed a group of employees of a nationwide financial organization in which a groupware system is used. They were questioned about two CMC applications: MSN with a higher level of synchronicity and email with a lower one. As a result, the larger the size of his/her own task network, the smaller its density and the higher the level of his/her centrality, the higher the level of the effect using the task network with CMC tools. Above all, this positive effect is verified to be much more produced while using CMC applications with higher-level synchronicity. Among the a variety of situations under which the use of CMC gives more benefits, this research is considered as one of rare cases regarding the characteristics of task network as moderators by focusing ITs for the operation of his/her own task network. It is another contribution of this research to prove empirically that the values of information system depend on the social, or comparative, characteristic of time. Though the same amount of time is shared, the social characteristics of users change its value. In addition, it is significant to examine empirically that the ITs with higher-level synchronicity have the positive effect on productivity. Many businesses are worried about the negative effect of synchronous ITs, for their employees are likely to use them for personal social activities. However. this research can help to dismiss the concern against CMC tools.

동래파전의 유래에 대한 문헌이 없어 문헌적 고찰이 이루어지지 않았다. 사례연구에 의하면 조선조에서 삼짇날 임금님께 진상한 음식(동래할매파전 옥호의 주인의 구술)인 상류층 음식으로, 벚꽃 피기전의 초봄의 계절음식 및 재실음식(이씨 및 왕씨 부부, 추씨 등의 민간구술)으로 이루어졌고 이로써 부산 향토음식임이 입증되었다. 동래파전의 식재료는 조선쪽파, 미나리, 해산물(대합, 홍합, 조갯살, 굴, 새우, 논고동), 쇠고기, 계란, 찹쌀 및 멥쌀가루, 맛국물(멸치, 다시마 국물)등이며, 이들 식재료를 조리 순서대로 얹어 참기름으로 구워낸 것으로 5가지 기초 식품군이 골고루 배합된 음식이다. 동래파전의 표준화에서 맛에 관련된 인자는 식재료 인자와 열원인자를 들 수 있다. 식재료 인자 중 찹쌀 및 멥쌀 가루에 멸치와 다시마의 국물을 섞은 반죽에서 쌀가루의 전분과 파가 어우러져 파전에 깊은 맛을 주고, 맛국물은 구수한 맛과 칼슘을 공급하여 파전에 맛과 영양의 상승효과를 주고 있으며, 참기름은 불포화지방산의 공급과 함께 파전에 유지맛과 고소한 맛을 주고 있다. 또한 조리 시, 강한 열원에서 번철을 달구어 식재료를 순서대로 얹어 뒤집고, 다시 반죽을 얹어 뚜껑을 덮은 후 열원을 약하게 하여 쌀 전분의 완전호화를 도와 파전의 깊은 맛을 배가시킨다 동래파전의 100g 당 에너지는 148 kcal, 단백질 8.8 g, 지방 2 g, 식이섬유 8.6 g, 칼슘 57.7 mg, 철분이 1.8 mg이었으며 1인분(245 g)당 에너지는 364 kcal, 단백질은 21.6g, 칼슘은 141 mg, 철분은 4.4 mg으로, 철분과 단백질의 함량이 우수한 것으로 나타났다. 아미노산 조성은 시스틴, 리신, 루이신, 발린, 이소루이신 등의 필수 아미노산의 함량이 높았으며 필수 및 비필수 아미노산의 조성이 균형된 음식이다. 구성 지방산 중 올레인산, 리놀레산, 리놀렌산의 함량이 각각 20.5%, 20.1%, 10.4%로 불포화지방산이 58.3%이었으며 P/M/S가 0.73/0.67/1이었다. 동래파전의 섭취 증가를 위하여서는 자주 먹을 수 있는 일상의 음식으로, 또 저 연령층의 섭취확대를 위한 급식메뉴로, 그리고 때와 장소의 구애 없이 간편히 이용할 수 있고, 우리국민은 물론 외국인의 입맛을 공략할 수 있는 조리방법 개발에 많은 노력과 연구가 필요하다고 생각한다. 본 연구에서는 전통적, 향토적 동래파전의 식재료 종류와 분량, 조리법에만 중점을 둔 조리표준화를 행하였으나 향후의 연구는 동래파전의 산업화에 중점을 두고 젊은 층을 중심으로 고 연령층 등 각 연령층이 선호할 수 있는 우리전통음식인 동래파전 패스트푸드화에 노력을 기울여야 할 것이다.

본 연구의 목적은 기존의 산업용 보일러에서 이산화탄소 배출저감을 위하여 연소가스 재순환에 의한 고온 순산소 연소기술을 개발하는데 있다. 이를 위해 실험실 규모의 LNG 연소기에서 연소 화염특성을 평가하기 위한 조직적인 수치해석 연구가 일차적으로 수행되었다. 특히 본 연구에서 고려한 중요한 변수는 산소부화환경에서 계산된 연소가스의 재순환 정도이다. 배기가스 재순환이 없는 100% 순산소 연소환경에서 화염은 고온의 길고 가는 층류형상의 화염을 보였다. 이는 산화제 중에서 질소성분이 감소함으로써 약화된 난류혼합효과와 $N_2$ 가스에 의한 현열손실의 감소에 기인하는 것으로 판단하였으며 문헌에 발표된 실험과 일치된 결과를 보였다. $O_2/CO_2$ 혼합가스에서 $CO_2$ 가스의 재순환율이 증가될수록 산화제의 유량 증가에 따른 강화된 난류혼합으로 인해 최고 화염온도가 버너 근처로 이동한 반면 전반적인 연소가스 온도는 $N_2$에 비해 $CO_2$의 높은 비열로 인해 낮아지는 현상을 보였다. 결국 80% 이상 $CO_2$ 가스를 재순환한 경우 연소가스의 온도가 급격하게 떨어지는 화염소멸 현상을 보여주었다. 그러나 30% $O_2/70%$ $CO_2$의 혼합 연소조건에서는 기존의 공기연소와 유사한 가스온도를 나타내었다. 이외에도 공기연소와 동일한 유량조건에서 난류강도와 열수지 측면에서 화염특성 변화를 평가하기 위한 면밀한 연구가 수행되었다.
