It is assumed that menarche is affected not only by the biological factors such as nutrition and genetic heritage, but also it is affected by other socio-cultural environmental factors including weather, geographic location, education and level of modernization. Also recent trend of menarche in Korea indicates that a lot of discussion are being generated to the need of sex education as a part of formal school education. The purpose of this study is to develop the school health education program by determine the age of menarche, the factors relavant to time of menarche and psycho-mental state of students at the time in menarche and investigate the present state of school health education relate to menarche of adolescents. The total number of 732 girls was drown from first, second and third grades of 4 middle schools in Seoul. For the data collection the survey was conducted during the period from May 1 to May 20, 1982 by using prepared questionair. The major results are summarized as follow; 1. Mean age at menarche and the percent distribution of menarche experienced. It was observed that about 68.7% of sampled students have been experienced menarche at the time interviewed. For the each group, age at menarche is revealed that among the students about 37.8% are experienced menarche for under 12 years old group, 62.1% for 13 year-old group, 80.6％ for 14 year-old group and 95.5% for over 15 years old. In sum it was found that the mean age at menarche was 12.3 years old, ranged from age at 10 as earlist the age at 15 as latest. 2. Variables associated with age at menarche. 1) There was tendency those student who belong to upper class economic status have had menarche earlier than those student who belong to lower class. Therefore, economic status is closely related to age at menarche. 2) In time of mother's education level, it is also found that those students whose mother's education levels from high school and college are experienced menarche earlier than those students whose mother's education levels from primary school and no-education. 3) However, in connection with home discipline, there was no significant relationship between age at menarche and home disciplines which are being treated "Rigid", "Moderated ", "Indifferent". 4) Degree of communication between parents and daughter about sex matters was found to be associated each others in determination of age at menarche. 5) It was found that high association between mother's menarche age and their daughter's menarche age was observed. Mother's age at menarche earlier trend to be shown also as earlier of their daughters. 6) Those students belong to "D & E" of physical substantiality index are trend to be earlier in menarche than those students in the index "A & B". 3. Psycho-mental state at the time of menarche. Out of the total students 68.2% had at least one or more than one of subjective symptoms. Shyness was shown as most higher prevalent symptom and others are fear, emotional instability, unpleasant feeling, depression, radical behavior, inferior complex and satisfaction appeared. Very few cases are appeared be guilty and stealing feeling. 4. The present status of school health education program related to menarche. As to the source of information about menarche, teacher was a main source with average index 5.88 and the other informants were mother & family member, friends, books and magagines, movies, television, and radio. For the problem solving at menarche, mother & family members were subject to discussion with an average index 6.02 as high. The others for discuss and knowledge about menarche were books, magagine, friends, teachers, and self-learning based on own experienced. The time of learning about menarche, it was learned as highest percentage with 43.2% at a 6 grades of primary school, middle school with 34.4%, 5 grade of primary school with 18.2%, and 4 grade of primary school with 4.0% respectively.

Objectives: 현재 장애인의 구강건강은 구강건강전문인력인 치과위생사가 아닌 사회복지사가 책임지고 있는 실정이다. 장애인 복지시설에 상주하는 사회복지사에게 올바른 구강건강 관리방법을 제공함으로써 장애인 구강건강의 형평성 제고를 도모하고자 한다. Methods: 2019년 4월 13일부터 2019년 4월 20까지 서울시 송파구에 위치한 'o' 장애인 복지시설에 거주하는 1급 지적장애인을 대상으로 식후 치과위생사 4명과 사회복지사 4명이 잇솔질 시행 후 구강환경관리능력지수(PHP Index)를 측정하여 비교하였다. 사전에 사회복지사 4명에게 잇솔질(회전법)을 교육하였으며, 잇솔질 방법과 검사 측정 도구를 통일하였다. 대상자의 구강보건지식을 평가하기 위해 자기기입식 설문지를 사용하였고, 구강보건지식점수 및 구강환경관리능력지수(PHP index) 점수의 평균, 대상자의 일반적 특성에 대해 Microsoft Office Excel ver.2016 을 이용하여 빈도 및 백분율 산출하였다(N%). Results: 치과위생사와 사회복지사의 구강보건지식 조사에서 모든 문항에서 치과위생사가 높은 점수를 나타냈다. 치과위생사와 사회복지사가 지적장애인을 대상으로 잇솔질(회전법) 실시 후 구강환경관리능력지수(PHP Index)를 비교했을 때 연령별, 성별 모든 분류에서 치과위생사의 구강환경관리능력지수(PHP Index)가 낮게 나타났다. 2차에 걸쳐 치과위생사와 사회복지사가 지적장애인을 대상으로 잇솔질(회전법) 실시 후 구강환경관리능력지수(PHP Index)를 비교했을 때 1차, 2차 모두 치과위생사의 구강환경관리능력지수(PHP Index)가 낮게 나타났다. Conclusions: 이상의 결과를 종합해 볼 때, 장애인들의 구강건강관리를 위해 치과위생사가 사회복지사보다 구강건강관리능력이 더 효율적인 것으로 나타났다. 따라서 장애인들의 입소시설에 치과위생사가 구강건강관리전문 인력으로 배치되어 장애인 및 사회복지사의 교육을 담당할 수 있는 환경이 조성되어야하며, 치과위생사를 양성하는 대학의 교육과정에도 장애인의 특성을 이해하는 교과목이 개설되어 전문성이 제고되어야 한다.

논의 시기별 파장별 분광반사특성을 조사하기 위해, Landsat TM 밴드, RVI, 습윤도의 특성을 분산분석한 결과, 가시광선 영역의 TM 밴드 1, 2, 3의 논지역 평균 자료값은 식물색소에 의한 광흡수와 관련이 많아 군락형성이 최대인 8월 19일과 9월 1일에 가장 낮아졌다가 등숙기인 9월 중 하순에 다시 높아졌다. 중간 적외선 영역인 TM 밴드 5와 7은 수분에 민감하여, 담수상태로 수체의 영향이 컸던 5월 31일과 6월 2일의 자료값이 가장 낮았고, 군락의 최성기에서 성숙기로 접어들면서 식물체의 수분함량이 줄어들어 자료값이 점점 높아졌다. 한편, RVI는 출수ㆍ개화기인 8월 19일과 9월 1일에 가장 높았고, 습윤도는 벼의 생육초기에서 성숙기로 갈수록 계속 낮아졌다. 이앙기인 5월 31일, 출수기인 8월 19일 두시기 자료에서 수분에 민감한 TM 밴드 5, 식생의 특징이 드러나는 RVI, 또한 모든 밴드의 특성이 포함된 습윤도를 벼 재배면적 추정을 위한 정보로 이용하여, 이앙기에 담수상태이고 같은 지역이 출수기에 무성한 식생의 특징을 보이는 곳을 벼 재배지역으로 정하여 벼 재배면적 지도를 작성하였다. 벼 재배면적은 7291.19ha 추정되었고, 지형도를 이용한 100지점의 정확도 검증 결과 92%로 나타났다. 1991년 5월 31일과 8월 19일 두 시기의 Landsat TM 밴드 3, 4, 5, RVI 및 습윤도를 각각 유효밴드로 선정하여 중첩한 총 10개의 밴드를 가진 화상을 생성하여 기존의 분류법에 이용하였다. 최대우도법에 의한 감독분류 결과 벼 재배면적은 9100.98 ha였다. Error matrix에 의한 분류정확도는 97.2%로 나타났고, 지형도를 이용한 정확도는 95%로 나타났다. 분류항목수를 15개와 20개로 한 ISODATA법에 의한 비교사 분류결과 벼 재배면적이 각각 6663.60ha와 5704.56 ha로 추정되었고, 지형도에 의한 분류정확도는 각각 87%와 82%로 나타났다. 통계연보를 기준자료로 하여 분류방법간 비교를 위하여 당진군 우강면에 대하여 벼 재배면적 비교를 한 바 감독분류에 의해 2522.97ha로 가장 크게 추정되었고, 다음이 규칙기반분류와 분류항목수를 20으로 한 무감독분류법으로 각각 1567.31 ha와 1865.61 ha로 추정되었다. 분류항목수를 15로 한 무감독분류에 의한 벼 재배면적이 1638.72 ha로 가장 작게 추정되었다. 이때, 통계연보 자료상의 우강면의 논면적(2242.69ha)에 가장 가깝게 추정된 결과는 규칙기반분류이었다. 벼 재배지역은 추정방법에 관계없이 이앙기와 출수기, 두 시기의 자료를 이용한 경우 다소 차이는 있으나 정확하게 구분되었다. 위성의 분광반사 특성을 이용한 규칙기반분류는 매우 쉽고, 재현성이 있으며, 넓은 지역에 대한 신속한 작업이 가능하다.

Despite the decrease in the number of children due to low birth rate, the domestic children's apparel market has been achieving steady growth as family income is rising thanks to more opportunities for working women, parents spend more on their children, and they prefer brand products that make their children look special. In addition, the market is suffering from hard competition as large enterprises have joined the race. The present study purposed to survey the children's apparel market in Korea, which is in a transitional period, and to contribute to the development of the market with Korean brands. For this purpose, we analyzed the characteristics of children's apparel brands in the 21st century based on the current state of the domestic children's apparel market and, based on the findings, forecasted the future trend of children's apparel brands, suggested improvements for expected problems, proposed standards for coping with changes such as diversification, high quality and differentiation in the children's apparel market, and provided consumers with information on how to purchase products. According to the result of analyzing the characteristics of children's apparel brands in the 21st century, brands are categorized largely into four types - life cultural brands, functional product brands, character brands and brands advancing to China. Life cultural brands equipped with all necessities for children are expanding, and with the deepening social problems of environmental pollution and the reduction of the child population, functional products made of environment-friendly materials are spreading widely, targeting infants and children. Furthermore, for extending age targets and diversifying products, children's apparel is using characters. The use of characters is expected to have a considerable effect on the growth of brands because children are more subjective as consumers than before and they are more easily persuaded with characters. Domestic children's apparel brands advancing to China have a high expectation of success in overcoming the limitation of the local market that has reached its peak and growing into global brands. Korean apparel makers are struggling to overcome the depressed domestic market, to recover consumers' consumption, to cope with market opening, to pursue high value of sensibility and to expand the seniors' market, etc. In this situation, future trends of children's apparel brands will be the expansion of family brands, brand totalization, quality price, niche market (pre-teen market), etc. In response to these trends, we made the following suggestions for improvement. 1. Children's apparel brands are evolving into family brands as well as into total brands through voluming. Today, however, apparel makers are advancing to the children's apparel market with the concept of adults' apparel and, as a result, children's apparel is merely adults' apparel of reduced size, having problems in design, color and materials. Thus, apparel makers must develop design considering the wide range of size and the characteristics of children's apparel, strengthen sourcing abilities to create revenues, and make thorough survey of customers to find common denominators between adults' apparel and children's apparel considering that characteristic that the target class is different from the buyer class. Furthermore, they must make active investments in human resources, develop outstanding products through advanced planning and design, and support marketing techniques and management systems to stores. 2. As the declining birth rate will continue to have a negative effect on the market, it may be difficult to expand the market size but there is still a margin for growth through high-sensibility and high-quality products. The competitiveness of brands is determined by their market shares. Accordingly, concepts should be specialized according to lifestyle, customers' diverse needs should be satisfied, and cross-coordination should be achieved within a brand. 3. Considering Korean parents who do not spare investment in their children despite shrinking consumption, functional products must be high value-added goods that can enhance efficiency. However, in the current situation of the infants' apparel industry where a textile manufacturer supply its products to multiple brands, it is difficult to develop unique products only based on materials. Thus, it is considered urgent to appeal to consumers not by relying on materials only but by finding methods of applying their own characters to children's dress.

This Study involved the development of a survey form and the collection of data in an effort-to provide information which can be used in the improvement of nursing curricula. The data examined were the kinds courses currently being taught in the curricula of nursing education institutions throughout Korea, credits required for course completion, and year in-which courses are taken. For the purposes of this study, curricula were classified into college, nursing school and vocational school categories. Courses were directed into the 3 major categories of general education courses, supporting science courses and professional education course, and further subdirector as. follows: 1) General education (following the classification of Philip H. phoenix): a) Symbolics, b) Empirics, c) Aesthetics. 4) Synthetics, e) Ethics, f) Synoptic. 2) Supporting science: a) physical science, b) biological science, c) social science, d) behavioral science, e) Health science, f) Educations 3) Professional Education; a) basic courses, b) courses in each of the respective fields of nursing. Ⅰ. General Education aimed at developing the individual as a person and as a member of society is relatively strong in college curricula compared with the other two. a) Courses included in the category of symbolics included Korean language, English, German. Chines. Mathematics. Statics: Economics and Computer most college curricula included 20 credits. of courses in this sub-category, while nursing schools required 12 credits and vocational school 10 units. English ordinarily receives particularly heavy emphasis. b) Research methodology, Domestic affair and women & courtney was included under the category of empirics in the college curricula, nursing and vocational school do not offer this at all. c) Courses classified under aesthetics were physical education, drill, music, recreation and fine arts. Most college curricula had 4 credits in these areas, nursing school provided for 2 credits, and most vocational schools offered 10 units. d) Synoptic included leadership, interpersonal relationship, and communications, Most schools did not offer courses of this nature. e) The category of ethics included citizenship. 2 credits are provided in college curricula, while vocational schools require 4 units. Nursing schools do not offer these courses. f) Courses included under synoptic were Korean history, cultural history, philosophy, Logics, and religion. Most college curricular 5 credits in these areas, nursing schools 4 credits. and vocational schools 2 units. g) Only physical education was given every Year in college curricula and only English was given in nursing schools and vocational schools in every of the curriculum. Most of the other courses were given during the first year of the curriculum. Ⅱ. Supporting science courses are fundamental to the practice and application of nursing theory. a) Physical science course include physics, chemistry and natural science. most colleges and nursing schools provided for 2 credits of physical science courses in their curricula, while most vocational schools did not offer t me. b) Courses included under biological science were anatomy, physiologic, biology and biochemistry. Most college curricula provided for 15 credits of biological science, nursing schools for the most part provided for 11 credits, and most vocational schools provided for 8 units. c) Courses included under social science were sociology and anthropology. Most colleges provided for 1 credit in courses of this category, which most nursing schools provided for 2 creates Most vocational school did not provide courses of this type. d) Courses included under behavioral science were general and clinical psychology, developmental psychology. mental hygiene and guidance. Most schools did not provide for these courses. e) Courses included under health science included pharmacy and pharmacology, microbiology, pathology, nutrition and dietetics, parasitology, and Chinese medicine. Most college curricula provided for 11 credits, while most nursing schools provide for 12 credits, most part provided 20 units of medical courses. f) Courses included under education included educational psychology, principles of education, philosophy of education, history of education, social education, educational evaluation, educational curricula, class management, guidance techniques and school & community. Host college softer 3 credits in courses in this category, while nursing schools provide 8 credits and vocational schools provide for 6 units, 50% of the colleges prepare these students to qualify as regular teachers of the second level, while 91% of the nursing schools and 60% of the vocational schools prepare their of the vocational schools prepare their students to qualify as school nurse. g) The majority of colleges start supporting science courses in the first year and complete them by the second year. Nursing schools and vocational schools usually complete them in the first year. Ⅲ. Professional Education courses are designed to develop professional nursing knowledge, attitudes and skills in the students. a) Basic courses include social nursing, nursing ethics, history of nursing professional control, nursing administration, social medicine, social welfare, introductory nursing, advanced nursing, medical regulations, efficient nursing, nursing english and basic nursing, College curricula devoted 13 credits to these subjects, nursing schools 14 credits, and vocational schools 26 units indicating a severe difference in the scope of education provided. b) There was noticeable tendency for the colleges to take a unified approach to the branches of nursing. 60% of the schools had courses in public health nursing, 80% in pediatric nursing, 60% in obstetric nursing, 90% in psychiatric nursing and 80% in medical-surgical nursing. The greatest number of schools provided 48 crudites in all of these fields combined. in most of the nursing schools, 52 credits were provided for courses divided according to disease. in the vocational schools, unified courses are provided in public health nursing, child nursing, maternal nursing, psychiatric nursing and adult nursing. In addition, one unit is provided for one hour a week of practice. The total number of units provided in the greatest number of vocational schools is thus Ⅲ units double the number provided in nursing schools and colleges. c) In th leges, the second year is devoted mainly to basic nursing courses, while the third and fourth years are used for advanced nursing courses. In nursing schools and vocational schools, the first year deals primarily with basic nursing and the second and third years are used to cover advanced nursing courses. The study yielded the following conclusions. 1. Instructional goals should be established for each courses in line with the idea of nursing, and curriculum improvements should be made accordingly. 2. Course that fall under the synthetics category should be strengthened and ways should be sought to develop the ability to cooperate with those who work for human welfare and health. 3. The ability to solve problems on the basis of scientific principles and knowledge and understanding of man society should be fostered through a strengthening of courses dealing with physical sciences, social sciences and behavioral sciences and redistribution of courses emphasizing biological and health sciences. 4. There should be more balanced curricula with less emphasis on courses in the major There is a need to establish courses necessary for the individual nurse by doing away with courses centered around specific diseases and combining them in unified courses. In addition it is possible to develop skill in dealing with people by using the social setting in comprehensive training. The most efficient ratio of the study experience should be studied to provide more effective, interesting education Elective course should be initiated to insure a man flexible, responsive educational program. 5. The curriculum stipulated in the education law should be examined.

In this study, the concentrations of particulate organic constituents of environmental tobacco smoke(ETS) were determined using an environmental smog chamber, where ETS is the sole source of target compounds. ETS was generated in a 30 ㎥ environmental chamber by a number of different cigarettes, including the Kentucky 1R4F reference cigarette and eight commercial brands. A total of 12 experimental runs was conducted, and target analytes included a group of ETS markers both in vapor and particulate phase and a class of polycylic aromatic hydrocarbos(PAHs) associated with ETS particles. The mass concentrations of PAH in ETS particles were also determined. The average contents of benzo(a) pyrene and benzo(a) anthracene in ETS particles for the commercial brands were 12.8 and 21.5$\mu\textrm{g}$/g, respectively, There values are all somewhat higher than those determined previously by other studies. Results form the chamber study are further used to estimate the average and variability of cigarette yields for target compounds associated with ETS. Finally, ratios of RSP to the surrogate standards of UVPM, FPM and solanesol were calculated for each sample. The average conversion factors factors for the eight commercial brands were 7.3, 38, and 41 for UVPM, EPM, and solanesol, respectively. The UVPM and FPM factors are in good agreement with the recently published values. Whereas there might be a substantial difference in the solanesol content among cigarettes produced in different countries, the variability is somewhat greater than those of UVPM and FPM, Unfortunately, comparison of the PAH yield data from this study with literature values was complicated by a lack of consistency in cigarette smoke generating methodology. Validation of the PAH yields was also difficult due to a lack of information on the ETS related PAH in the literature. From and engineering viewpoint , however, these data on the cigarette yields of ETS components may still provide useful information to studies on the mathematical modeling of indoor air quality management regarding tobacco smoke as a source of interest, or to studies on the assessment of human exposure to ETS.
