The specific purpose of this study was as follows: 1) To identify the level of sexual awareness and demand for sex education of teenagers, their parents and teachers. 2) To investigate the attitude toward and acceptance of heterosexual friendships by teenagers, their parents and teachers. 3) To identify the experience and direction of sex education of parents and teachers. For this purpose, this study selected 341 male and female teenagers at three high schools located in a city, 119 parents with high school students and 243 elementary/middle/high school teachers. The structured questionnaire was distributed to each of them and returned by them. This study was conducted over the period between June 1. 2001 and Aug 31. 2001. A total of 720 questionnaires were distributed to them and 703 were returned. Data analysis was conducted to obtain percentage and frequency using the SAS program. As a result, the following findings were obtained: Parents and teachers showed a similar attitude about sexual awareness, but teenagers showed a different attitude. In terms of the level of feeling of and interest in 'sex', teenagers, parents and teachers were comfortable in accepting it. As for sexual curiosity in puberty, 84.8% of the parents and 95.5% of the teachers responded that it was natural, whereas only 14.7% of teenagers responded that it was natural. But As for the item that 'sex is natural as one of human needs', 3.6% of the teenagers, 16.8% of the parents and only 1.2% of the teachers responded that it was not. As for the item that 'A man has a stronger sexual impulse than a woman', 6.1% of the teenagers, 16.8% of the parents and 17.3% of the teachers responded that it was not. 64.2% of the teenagers and 90.2% of the teachers responded that it was impossible to overcome the sexual impulse, whereas only 8.4% of the parents responded that it was possible. As for the item of masturbation, 64.5% of the teenagers responded that it was possible for male students and not possible for female students. 67.2% of the parents and 91.1% of the teachers responded that it was possible regardless of sex. As for the item of an attitude toward virginal purity, both the parents and teachers showed that virginal purity was important for both man and woman, but teenagers showed a weak awareness of virginal purity. As for the item, 'It is possible to have sexual intercourse with a lover during adolescence', 20.2% of the teenagers, 79% of the parents and 87.7% of the teachers responded that it was impossible. As for the item 'It is necessary to keep premarital virginal purity for a happy married life', 21.1% of the teenagers, 74.8% of the parents and 55.1% of the teachers responded that it was necessary, which shows that teenagers had a different opinion than parents and teachers. In case of pregnancy in adolescence, most of the responding teenagers, parents and teachers chose abortion. As for the item 'female refusal on male sexual approach', respondents accepted female refusal as they did for orders of teachers, parents and adolescents. As for item 'An assaulter is entirely to blame for sexual assault', all of three groups responded in the affirmative.

Objective : The purpose of this study is to investigate about comparison of Eastern-Western medicine on the acne. Methods : We searched Eastern and Western medicine books for acne. We analyzed these books and examined category, definition, etiology, classification, internal and external methods of treatment of acne. Results : The results were as follows. 1. In Eastern medicine, Acne belongs to the category of the Bunja(粉刺), Jwachang(痤瘡), Pyepungbunja(肺風粉刺). In Western medicine, the other name of Acne is acne vulgaris. 2. In Eastern medicine, the definition of Acne includes manual extraction of comedones and skin appearance. In Western medicine, Acne is a common skin disease during adolescence and a chronic inflammatory disease of pilosebaceous unit of self localization. It is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules and it affects the areas of skin with the densest population of sebaceous follicles, these areas include the face, neck, back, and the upper part of the chest. 3. In Eastern medicine, the cause and mechanism of Acne arose from the state of internal dampness-heat and spleen-stomach internal qi deficiency due to dietary irregularities and then invaded external pathogen such as wind-dampness-heat-cold-fire in lung meridian lead to qi and blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of Acne; Androgen-stimulated production of sebum, hyperkeratinization and obstruction of sebaceous follicles, proliferation of Propionibacterium acnes and inflammation, abnormaility of skin barrier function, genetic aspects, environmental factors etc. 4. In Eastern medicine, differentiation of syndromes classifies clinical aspects, and cause and mechanism of disease; the former is papular, pustular, cystic, nodular, atrophic, comprehensive type; the latter is lung blood heat, intestine-stomach dampness-heat, phlegm-stasis depression, thoroughfare-conception disharmony, heat toxin type. In Western medicine, it divides into an etiology and invasion period, and clinical aspects; Acne neonatorum, Acne infantum, Acne in puberty and adulthood, Acne venenata; Acne vulgaris, Acne conglobata, Acne fulminans, Acne keloidalis. 5. In Eastern medicine, Internal methods of treatment of Acne are divided into five treatments; general treatments, the treatments of single-medicine and experiential description, the treatments depending on the cause and mechanism of disease, and clinical differentiation of syndromes, dietary treatments. In Western medicine, it is a basic principles that regulation on production of sebum, correction on hyperkeratinization of sebaceous follicles, decrease of Propionibacterium acnes colony and control of inflammation reaction. Internal methods of treatment of Acne are antibiotics, retinoids, hormone preparations etc. 6. In Eastern medicine, external methods of treatment of Acne are wet compress method, paste preparation method, powder preparation method, pill preparation method, acupuncture and moxibustion therapy, ear acupuncture therapy, prevention and notice, and so on. In Western medicine, external method of treatments of Acne are divided into topical therapy and other surgical therapies. Topical therapy is used such as antibiotics, sebum regulators, topical vitamin A medicines etc and other surgical therapies are used such as surgical treatments, intralesional injection of corticosteroids, skin dermabrasion, phototherapy, photodynamic therapy, and so on. Conclusions : Until now, there is no perfect, effective single treatment. We think that Eastern medicine approach and treatment can be helpful to overcome the limitations of acne cure.

이 연구는 한국 재래 닭에서 부화 후 고환 발달 과정을 명확하게 이해가기 위하여 부화 후 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 21, 28, 32, 44, 52 및 64주령(n=13마리/일령)의 한국 재래닭을 이용하여 수행하였다. 한국 재래 닭의 고환은 2.5 % glutaraldehyde를 이용하여 전신 관류 고정하고 조직 처리 과정을 거쳐 Epon-araldite에 포매하였다. 초박절편기를 사용하여 $1{\mu}m$로 절편한 다음 methylene blue로 염색하여 일반적인 조직의 변화상과 형태 계측을 일반적인 방법에 따라서 정자 생성을 측정하여 다음과 같은 결과를 얻었다. 부화 후 1주령의 고환의 평균 무게는 0.015 g이었고 점진적으로 증가하여 21주령에는 3.93 g이고 21주령부터 64주령까지는 변화가 없었다. 곱슬정세관의 용적 치밀도는 1주령에 32.6%이었으나 점차적으로 증가하여 64주령에서는 92.89이었다. 1주령의 한국 재래 닭 고환 간질 조직은 고환 실질의 67.4%를 나타내었고 이러한 비율은 성장하는 동안에 점차적으로 감소하여 64주령에 7.11%를 나타내었다. 고환내 총 정자 생성은 18주령부터 28주령까지는 유의성있게 증가하였고 고환 1g당 정자 생성은 $18\sim28$주령까지는 유의성있게 증가하였고 $28\sim52$주령까지는 변화가 없었으나 64주령에 유의성 있게 감소하였다. 곱슬정세관의 평균 직경은 $1\sim21$주령까지 주령에 따라 점진적으로 증가하였고 곱슬정세관의 길이는 1주령에 0.34 m이었고 성장하면서 유의성 있게 증가하여 64주령에서는 72.2 m이었다. 곱슬정세관내 생식세포의 발달 단계는 다음과 같이 분류할 수 있다. 1) 정조세포($1\sim8$주령), 2) 정조세포, 정모세포($10\sim12$주령), 3) 정조세포, 정모세포, 원형의 정자세포($14\sim16$주령), 4) 정조세포, 정모세포, 정자세포 및 정자($18\sim64$주령). 이러한 결과를 종합하여 보면 한국 재래 닭에서 부화 후부터 성숙시기까지 고환 발달의 양상은 신생시기-성 성숙 이전기($1\sim12$주령), 성 성숙시기($14\sim18$주령) 및 성숙시기$(21\sim64)$로 나뉜다.
