본 연구에서는 기능성 제빵제품 개발의 일환으로 라디치오 분말을 첨가하여 스펀지 케이크를 제조하고, 분말 첨가 비율(1~7%)에 따른 스펀지 케이크의 품질 특성 및 항산화 활성을 분석하여 적절한 라디치오 분말 첨가량을 제시하고자 하였다. 라디치오 스펀지 케이크의 pH는 라디치오 분말을 첨가함에 따라 유의적인 차이를 보이지 않았다으나, 감소하는 경향이 나타났다. 스펀지 케이크의 비중은 유의적으로 증가하는 결과를 보였다. 수분 함량은 감소하였으며, 굽기 손실률은 증가하는 경향을 보였다. Crust의 색도는 라디치오 분말의 첨가 수준에 따라 L, a, b값이 유의적으로 감소하였고, Crumb의 색도는 L값과 b값이 감소하고, a값은 증가하는 경향을 보였다. 조직감 측정에서는 경도와 씹힘성이 점차 감소하였고, 응집성과 탄력성은 유의적인 차이가 없었다. 라디치오 분말 첨가량에 따라 총 폴리페놀 함량이 유의적으로 증가하였고, DPPH 라디칼 소거능 측정에서 $IC_{50}$은 점점 감소하여 라디치오 분말을 첨가할수록 스펀지 케이크의 항산화력이 높아지는 것으로 나타났다. 관능검사 결과, 향미, 단맛, 촉촉함, 씹힘성 등이 분말 첨가에 따라 감소하였으나, 3% 첨가군에서 색상 및 전반적인 기호도에서 높은 점수를 받아, 라디치오 분말을 첨가한 스펀지 케이크 제조 시 밀가루의 3%를 라디치오 분말로 대체하는 것이 가장 적절한 것으로 사료된다.

1개 의과대학 본과 제 1,2,3학년 279명을 대상으로 1987년 3월중순부터 4월초순에 걸쳐 프레밍헴 A형행동양상척도(FTA)의 신뢰도와 타당도 그리고 사회심리학적인 변수와 혈압과의 관계를 조사해서 다음의 결과를 얻었다. SCL-90-R과 FTA의 신뢰도는 $0.57{\sim}0.91$의 범위였고 FTA의 요인분석에서 정열적경쟁요인(hard-driving competitiveness factor)과 조급요인(impatience factor)이 추출되었다. FTA의 총점은 비교체중이 클수록, 농촌출신이면 높은 경향을 보였으나 유의성은 없었고 SCL90-R과는 우울, 불안, 적대감, 편집증, 정신증하위척도와 비교적 낮은 유의한 정상관관계를 보였다. 혈압과의 단일 변수 분석에서 수축기혈압은 남자에서 비교체중과 가족력이 유의했고 남녀 공히 경제상태에 따른 차이가 있었다. 확장기혈압은 남자에서 비교체중과 음주량이 유의했고 여자에서는 비교체중이 유의한 상관관계를 보였다. 비교 체중의 영향을 제거하고서는 남자에서 음주량이 확장기혈압과 경제상태가 수축기혈압과 유의한 관계를 보였다. 단계적추가분석법에 의한 중회귀분석 결과 남자에서는 수축기혈압에서 비교체중과 경제상태가 중요변수로 선정되었고 확장기혈압에서는 비교체중과 음주량이 선정되었다. Alpha가 0.1수준에서는 수축기혈압에 SCL-90-R의 우울증 하위척도가 추가 선정되었다. 여자에서 수축기혈압은 경제상태와 비교체중이 선정되었고 확장기혈압에서도 비교체중이 선정되었으나 대상자 수가 적어서 불안정했다. FTA와 혈압과는 남녀 공히 관련이 없었다.

It has been reported that CLA decreases fat deposition in vivo and in vitro experiments. Among CLA isomers, c9t11 and t10c12 have been shown to exert active biological activities. For example, t10c12 reduces body weight and increases lean body mass, whereas, c9t11 has little effect on body fattness. However, the underlying molecular mechanism for the anti-obesity action of CLA isomers are not well understood. The purpose of this study was to examine the effects of t10c12 and c9t11 on lipid accumulation, cell proliferation, cell death and the expression levels of Ucp genes which are proposed as targets for anti-obesity in 3T3-L1 preadipocytes. Isomers of CLA at 50$\mu$M were added into preadipocyte differentiation medium for 3, 6 and 9days. Control cells received only the vehicle in the differentiation medium. Cytochemical analyses for lipid accumulation, cell proliferation and apotosis were carried out to compare lipidogenesis and cellular activity. RT-PCR analysis of GAPDH, Ucp 2,3 and 4 were also performed to find any modulatory effects of CLA isomers on the metabolic genes. Lipid accumulation indicated by Oil Red-O staining was inhibited in CLA isomers as compared to the control. T10c12 isomer showed less lipidogenesis than c9t11 did. A decrease occurred in CLA isomers as shown by BrdU incorporation. Apotosis has occured at higher level in t10c12 when compared to that of t9c11. Ucp 2, 3 and 4 genes were also upregulated in CLA isomers. T10c12 showed higher level of Ucp gene expressions than the c9t11 did. The biological activities of CLA isomers were also found to be different during differentiation of 3T3-L1 preadipocytes, suggesting that different isomers may be active in certain stage of lipidogenesis. The results indicate that both c9t11 and t10c12 CLA isomers decrease lipidogenesis, inhibit cell proliferation, increase cell death and upregulate in Ucp gene expressions during 3T3-L1 preadipocyte differentiation. T10c12 isomer was more effective than c9t11 in overall anti-obesity activity.

Rapid socio-cultural and economic changes in the country has brought with it changes in the society's value system. For a traditional society that is increasingly being exposed to modernization but where sex norms are still very restrictive, the adolescent sexual mores takes on added significance. Adolescents are caught between two opposing forces, the changing environment that allows for freer and liberal mores and the traditional society that cannot keep pace with the changing environment and therefore demands resistance to changes. This paper focuses on problems of adolescent sexuality in this country and considers the countermeasures for the existing problems. Amongst the problems are: (a) increasingly younger age of the adolescents who start sexual intercourse (b) non-use of contraception, (c) unwanted pregnancies, (d) increase in the number of induced abortion and (e) increase in the number of unwanted children and unmarried mothers. The Korean adolescent's sexual behavior seems to follow that of the developed countries. In other words, many western modes of life and sexual values seem to bave been copied in Korea and yet Korean adolescents lack in their knowledge of sex related matters such as reproductive physiology and contraception. Among middle and high school students, female students are reported to have less knowledge on sex than male students according to a 1988 survey by KIPH. Even among the unmarried famale factory workers, only 42.5 percent replied they know of the condom, and 25.1 percent and 23.1 percent said they had knowledge of spermicide and menstrual regulation respectively. However, 14.9 percent and 13.9 percent reported that they had a knowledge of the loop and female sterilization respectively according to the 1984 study by KIPH. Among the middle school students 0.8 percent said they had experience in sexual intercourse, while 7.3 percent of the high school students reported having had sexual intercourse. The sexual intercourse experience rate among the unmarried female factory workers is 37.8 percent. Among those female factory workers with sexual experience, 46.7 percent had more than one sex partners. Only 39.1 percent of male students and 18.9 percent of female students among those with sexual intercourse experience have used contraceptives. mostly condoms and oral pills 45.1 percent of female factory workers with sexual intercourse experience used contraceptives such as pills, condoms and rhythm methods. The pregnancy experience rate among the female factory workers who had experience in sexual intercourse is 29.5 percent, which is 11.1 percent among the total respondents. Out of the 102 pregnant female workers, 98 workers(96.1 percent) terminated their pregnancy by induced abortion and 2 workders(2 percent) in natural abortion, while 1 worker(1 percent) was in pregnancy and another 1 worker had normal birth that was subsequently sent to orphanage. In order to cope with the problem of adolescent sexuality, a drastic and strong policy measures should be taken by the government. The most effective countermeasure to the adolescent sexual problems appears to the education. The sex and population education in the school is very much in need. In addition, sex education program through mass media and at the job sit-should be promoted for a healthy development of adolescents' sexual behavior. Also, the existing national family planning program, which has focused on the married couples, should be extended to the unmarried people in its scope and contents of the program.

Purpose: Most cases of primary hyperparathyroidism are due to parathyroid adenoma or parathyroid hyperplasia. Parathyroid carcinoma is a very rare cause of hyperparathyroidism. Although the diagnosis of parathyroid carcinoma is usually established by pathologic criteria especially of vascular or capsular invasion, some clinical and biochemical features differentiate it from benign forms of hyperparathyroidism. We under-took a retrospective study in 6 patients with parathyroid carcinoma, with the aim of conveying experience from management for this rare cause of hyperparathyroidism. Methods: Clinical symptoms, biochemical laboratory, radiologic, and intraoperative findings, local recurrence and distant metastasis were analyzed in 6 patients diagnosed pathologically as a parathyroid carcinoma after operation from 1992 to 2001. Results: Mean age was 50.2 years (33.0-60.0 years) and male to female ratio was 1:1. Neck mass was found in 5 patients, multiple bone pain in 3 patients and renal stone in 1 patient. One case has suffered from chronic renal failure for 19 years. Although preoperative laboratory evaluations showed the aspects of hyperparathyroidism in all cases, mean serum calcium level was 11.2mg/dl(10.5-12.1mg/dl), slightly elevated. Laboratory values after surgery were within the normal range in 5 cases. However, in one case with chronic renal failure, serum PTH levels, serially checked, were above the normal range. Any of imaging methods failed to suggest a parathyroid carcinoma preoperatively. Parathyroid adenoma was suspected in 3 cases, thyroid cancer in the other cases before surgery. The extent of resection was radical resection of parathyroid lesion with more than unilateral thyroid lobectomy and central compartment neck node dissection and in 2 cases, the resection of recurrent laryngeal nerve or strap muscles was added. During follow-up period, any local or systemic recurrence were not evident in all the cases. Conclusion: Although parathyroid carcinoma is a rare disease and its preoperative diagnosis, in our experience, could not easily be made, the understanding of characteristic clinical and biochemical feature could help diagnosis at first surgery. Radical resection without remaining residual tumor is most important for the management of the parathyroid cancer.

The present study was conducted to examine the effect of different levels of essential and nonessential amino acid in NCSU-23 medium on the in vitro-produced porcine embryo as it develops from the zygote to the blastocyst stage. Four experiments were performed, each with a completely randomized design involving 5 to 8 replications of treatments. In order to know the effect of nonessential amino acids in NCSU-23 medium, 0, 5, 10 and $20{\mu}/ml$ MEM were supplemented there to, (Exp. 1) and the medium was supplemented with same level of essential amino acids (Exp. 2). The combined effect of nonessential (0, 5, 10 and $20{\mu}/ml$ MEM) and essential amino acids (0, 5, 10 and $10{\mu}/ml$ MEM) in NCSU-23 medium (Exp. 3), first 72 h with non-essential amino acids (at 0, 5, 10 and $20{\mu}/ml$ MEM), and last 4 d with essential amino acids with the same level as NEAA (Exp. 4) were examined. The embryo development was monitored and the quality of blastocysts was evaluated by counting the number of total cells and determining the ratio of inner cell mass (ICM) to trophoectoderm (TE) cells. When Eagle's nonessential amino acids (MEM) added to NCSU-23 medium, it significantly increased the likelihood of development to the 2- to 4-cell stage and subsequent blastocyst development. Supplementation of different levels of essential amino acids in the NCSU-23 medium decreased cleavage rate, rate of morula and blastocyst development and the number of ICMs. In the case of the combined effect of essential and nonessential amino acids, better and significant results were found for blastocysts, hatching blastocysts and for ICM numbers which were also dose dependent. With respect to the biphasic effect of nonessential and essential amino acids, nonessential amino acids increased cleavage whereas essential amino acids increased the total cell number. Neither the nonessential nor the essential group of amino acids, on their own, affected blastocyst cell number or the differentiation of cells in the blastocyst. In conclusion, this study determined the role of nonessential and essential amino acids in the culture of the porcine embryo and showed that the embryo requires different levels of amino acids as it develops from the zygote to the blastocyst stage.
