  • Under the full consideration of the growing need and importance of population education in the field of home economics in Korea, the study was carried out to verify and assess the following facts on the current issues of population education of home economists who are presently engaging in teaching professions as the teachers of middle and high school and professors of college and universities by setting its primary objectives of the study as followings; 1) to assess the degree of general knowledge and attitudes of home economists toward population education in the field of home economics, 2) to verify the problems encountered in implementing population education by home economists in its field, 3) to find an existing status of previous trainings received and other activities of population education of home economists aimed at utilizing these findings as a part of reference materials when the population education is conducted in the field of home economics. In order to attain these objectives described above, the questionnaire was carefully designed to house a total of 40 questions with good combination of multiple-choice and the simple answer questions. The mail questionnaire survey was conducted by establishing teachers of home economics at middle/high schools and college/universities as Senior Home Economists(SHE) who are from public, private liberal arts and vocational schools. The rate of response observed during the survey was 45.6 percent and the findings of the survey research are as follows: 1) Examining the status of the respondents by residence and religion, it was found that 45 percent of middle & high school teachers ar.d 59. 1 percent of college professors are residing in Seoul city area and that the largest percent of them are christian in their religion. Analyzing respondents by their ages, 56 percent of middle/high school teachers are in their 30s, 45 percent of college professors are in their 40s, and 37 percent of college teachers are in their 30s. In addition, 13 percent of the total respondents are found to be unmarried. The study also revealed that 71 percent of the college professors finished Master Degree course and 82 percent of middle/high school teachers are graduated from college level lasting 4 years. Looking over the status cf major fields of respondents, 68.4 percent of middle/high school teachers are specialized in home economic education and the college professors, on the other hand, show relatively even prortion by specializing in the order of food & nutrition science, clothes & textile science and home managerial science. As far as the length of teaching experience is concerned, a relatively longer period of teaching experience is observed in the college professors in comparison with that of middle/high school teachers. In other words, 33.3 percent of middle/high school teachers are experienced in teaching from 6 to 10 years on average while 43.9 percent of college professors show more than 16 years of experience. 2) Examining the status of existing number of children cf the respondents, one boy and one daughter pattern is predominant, showing 28.5 percent in middle/high school teachers and 21.1 percent in college professors. As for the desired number of children of unmarried respondents, it is observed that 43.8 percent of middle/high school teachers desire to have one boy and one girl, and 31.3 percent of college professors want to have one child regardless of the sex. By assessing the degree of awareness of the population education through their students, it is observed that 53 percent of middle/high school teachers and 50 percent of college professors are aware of population education in some extent and that a majority of respondents took the positive attitudes toward an inclusion of family planning components into the formal school education. Another noteworthy to observe is that a total of 84.8 percent out of middle/high school teachers pointed that the population education currently conducted at schools as a part of home economics are less sufficient than it should be. 3) Analyzing the tendency as to whether the respondents were experienced in receiving population education during the time when they were students, 75 percent of college professors and 59 percent of middle/high school teachers responded negative answers in the survey. In the mean time, a total of 50 percent of the respondents replied that they began to acknowledge the importance of population education mainly through the participation of some sort of population-education orientend seminars, experienced by 40 percent of college professors and 80 percent of middle/high school teachers. 4) What it calls attention in this study was to find that 96.5 percent of middle/high school teachers and 72 percent of college professors conduct population education to some extent during their lecture hours and that more than 80 percent of them are never experienced in teaching population and family planning contents in their regular classes. It is, on the other hand, found that no more than once was the response of those who believe themselves that they are experienced in teaching these relevant components to their students. Analyzing the contents of the subjects being taught in the class, a large percent of them are found to be consisted of population and family planning contents. According to this study, the current population education through the formal school is quite inactive. Analyzing the facts, 44.9 percent of the college professors responded that the population and family planning components are quite apart from their specialization which eventually generates lack of interest in the field. 5) It is also noticed through the study that the degree of frequency of commenting on population and family planning contents during the classes was depending significantly on their specializations which means that the degree of frequency varies from a major to another. Those who majored in home managerial science was the first one, as compared to others who majored in different specializations. Glancing over the status of correlations between ages of the respondents and numbers of seminar paticipation, it is quite clear that the aged group participated more than the younger group did, and that the most highest number of participations made by college professors were those who are in 50s. In addition, it is also found that those who are aged 20s and 60s of the respondents were the group who comments least on the contents of population and family planning at their classes. The suggestions and recommendation made through this survey research are as follows. 1) No one denies that the rapid increase of population, as compared to the limited size of land and resources, will certainly affect adversly to an enhancement of individual life quality which will, eventually, bring forth the poverty of the nation. This is the reasson why we are insisting that the world population be controlled up to an optimum level with a matter of global concerns. It is our understading that the primary aim for reducing number of population is believed to be attained only by conducting the systematic and comprehensive population education through the formal schools. Therefore, the role of home economists in the field of population/family planning education is considered very importment due to the fact that an ultimate goal of population education is placed in elevating the quality of family life by having optimum number of children through family planning program. 2) It is quite clear that home economists as teachers of formal school in all level are invited to pay their attention on redefining the ultimate goal of education and that of population education. We also understant that the primary objective of population education is to change the norm and value of the clients by replenishing the students with pertinent knowledge and attitudes on population and its related problems through a sort of education in order to attain the ultimate goal for enhancing the quality of life. There is no exception in the theory of home economics. An altimate goal of home economics is to elevate the general quality of life through an establishment of value existed in daily life. Considering the relations between population education and home economics, it is quite indespensable to bandle population components as an integral part in the field of home economics. We believe, therefore, that the senior home economists positive participation in the effort population control is more needed than it has been. 3) It is also strongly urged that population education should be a part of instructor training course for home economics. In other words, the teacher of home economics should be well aware of population and its problems by teaching interrelationship between population education and home economics, needs, contents and methods of population education during the instructor training courese for home economics. In addition, the senior home economists should be encouraged through positive participation on the short term training by types of domestic and international seminar, workshop, etc. 4) We certainly believe that the population education can not sustain itself without any backing-up of information and findings' of various and comprehensive researches of natural and social sciences. Accordingly, every senior home economist is invited to exert their maximum effort to conduct systematic study with an aim to utilize these findings and information at best in population education in the field of home economics. Therefore, we consider that the development of training material is imminent in order to provide effective and efficient population education through the for training of home economies. It should be noted that these training materials must be carefully designed, tailored and developed to meet the different classes of trainees under the considerations as to whether it is easily adaptable and infusable into the curricula of every field of home economics, and it is acceptable in the degree of difficulty and quality in its contents. 5) It is true that there are many domestic and international research rapers, reports and findings in the field of population education and family planning. However, there is a tendency that the most of research papers are heavily relying on the authors intension and preferences in its expression and publication. Under these circumstances, it is urged that the home economists should aware of the growing need of the technical training in order to keep these available information and research findings reprocessed and redesigned to insure the practical application into the population education in the field of home economics in Korea.

  • 수도의 다수확을 위하여 근래 다비재배의 경향이 높아가고 있는 반면에 등숙률의 저하가 증수저해요인으로 크게 문제되고 있다. 특히 최근 육성된 통일품종은 이점이 더 심각한 바 있어 등숙의 향상책을 모색하고저 1970년부터 1972년까지 3개년간에 걸쳐 수원 작물시험장포장과 인공기상실에서 주로 진흥과 통일을 공시하여 증숙에 관한 일련의 실험을 시행한 바 그 결과를 요약하면 다음과 같다. 1. 통일의 곡립은 발아등 종래품종에 비하여 세장하고 곡립의 폭 및 두께가 작으며 비중과의 상관관계는 진흥에 있어서는 곡립의 무게, 두께, 폭 및 길이의 순으로 낮으나 통일은 무게, 폭, 두께 및 길이의 순으로 낮았다. 2. 비중별 립수분포에 있어서 종래의 Japonica도는 비중 1.18을 정점으로 대부분 1.12이상에 분포하고 있으나 통일계통에서는 1.12이하의 곡립도 상당수 분포하였고 진흥이 비중 1.06이하에서 정현비율이 급감하고 있으나 통일에 있어서는 비중 1.20에서 0.96까지의 곡립의 정현비율이 별로 차이가 없으므로 1.06을 등숙립의 선별기준으로 삼는 것은 불합리한 것으로 인정된다. 3. 출수후의 등숙속도는 품종간차이가 현저하며 대체로 한랭지 재배품종일수록 느렸으며 통일은 원래 등숙이 빠른 편이나 등숙후기에는 기온의 저하로 인하여 그 속도가 떨어졌다. 4. 지발분얼 또는 약세분얼은 수당영화수도 적을 뿐 아니라 등숙률도 낮은데 통일은 지발분얼이 많고 이들은 저온하에서 출수하여 수전일수가 연장되고 등숙률이 떨어졌다. 5. 통일의 엽신은 짧고 넓으며 엽신전개력은 다비조건에서는 진흥만큼 크고 또 엽의 경사각도는 적어 수광태세가 양호하였다. 통일 엽신의 단위동화능력은 고온하에서는 비교적 크나 저온하에서는 떨어졌다. 6. 통일은 단간이며 하위절간이 짧고 굵어서 도복저항성이 크고 출수전 저장탄수화물이 많았으며 인산, 규산, 석회, 망간 및 마그네슘 등의 체내함유율이 높았다. 7. 통일은 비교적 많은 영화수를 가지고 있고 진흥이 영화수와 등숙률간에 유의적인 역상관이 있음에 비하여 통일은 고온다조하에서는 영화수가 많아도 등숙률은 떨어지지 않고 영화수증가에 비례하여 수량이 많아졌다. 8. 진흥에 비하여 통일의 뿌리는 천근성이며 고온하에서는 그 활력이 컸으나 저온시에는 엽신이 황갈색으로 변하고 그 변색정도에 비례해서 뿌리의 활력도 떨어졌다. 9. 통일은 수광태세가 좋고 동화일호흡균형상 유리한 생산구조를 갖어 진흥보다 이상적인 모형이었다. 10. 수원지방의 수도보통기재배에 있어서 수량생산기간의 일사량은 비교적 풍부한 편이나 8월25일이후에 출수할 때에는 평균기온이 22$^{\circ}C$이하로 빠르게 하강하므로서 기온이 보다 등숙의 제한요인으로 인정된다. 11. 진흥이 저온하에서도 등숙율이 비교적 높은데 통일의 등숙적온은 $25^{\circ}C$이상이며 21$^{\circ}C$이하에서는 완전등숙이 거의 불가능하였다. 12. 진흥은 감광성이 비교적 크고 감온성은 중정도인데 비하여 통일은 감광성은 작으나 기본영양생장성과 저온하의 출수지연도가 컸었다. 13. 진흥은 질소의 후기중점시비에 의하여 등숙율이 향상되고 증수되었으나 통일에 있어서는 기비중점으로 질소를 시용하여 영화를 많이 확보하여도 등숙율저하가 적고 오히려 증수되였다. 14. 진흥은 만식적응성이 비교적 크나 통일은 조식효과가 크고 만식하면 출수가 지연되고 등숙온도가 낮아져서 등숙율과 수량이 떨어졌다. 15. 통일은 내비성과 밀식적응성이 커서 다비밀식조건에서 그 다수성을 발휘하는 특성을 가졌으며 주수 및 묘수증가에 의하여 수전일수가 단축되고 등숙률이 향상되었다. 16. 재식거리를 좁히고 어느 정도 주당묘수를 늘리면 강세분얼비율이 높아졌다. 17. 인산은 저온시에는 등숙율을 상당히 향상시켰다. 이상을 요약해보면 종래품종들의 등숙향상을 꾀하자면 8월20일이전에 출수시켜야 하며 10a당 질소 7.5kg 이상의 과다한 기비를 억제하고 후기중점으로 시비하여 동화효율을 높여야할 것이다. 한편 통일은 곡립이 세장하고 식물체가 작고 뭉툭한 등 종래품종과 판이한 외부형태와 더불어 그 생리생태적 특성도 상이한 점이 많으므로 등숙립선별, 도정 및 재배법상에도 종전품종과 다른 고려가 있어야 할 것이다. 즉 등숙립 선별기준에 대하여는 통일의 비중별 입수분포 및 정현비율로 보아 종래의 등숙립 선별기준인 비중 1.06 보다는 0.96을 적용하는 것이 합리적이고 도정상으로는 통일의 곡립이 세장하고 폭 및 두께가 작다는 것을 고려하여야 한다. 재배법에 있어서 통일의 등숙률이 낮은 원인이 주로 약세분얼이 많고 저온하에서는 출수가 지연되고 뿌리와 엽신의 기능이 저하되며 불임이 증가되는 것으로 판명되었고 그 외에 통일은 다비밀식적응성이 크므로 등숙향상과 수량 증대를 위해서는 적극적인 방법으로서 우선 견실하고 큰 묘를 가능한 한 조식하고 다비밀식상태로 재배하되 충분한 기비를 시용하고 묘수를 3본 내외로 심고 인산 및 규산등을 충분히 시용하여야 할 것이다.
