A total of 102 patients who had an Open Heart Surgery from April 1976 to July 1981 were reviewed. 55 paeitnts were congenital heart disease and 47 patients were acquired heart disease. Among SS patients of congenital heart disease, 18 T 0 F, 18 V S D, 8 A S D, and each one case of l\ulcorner 0 R V, Truncus arteriosus, Ebstein anomaly, Single ventricle, P D A, P 5, A S D + P 5, E C D, V 5 D + P D A, A - P window, D C R V were noted respectively. In 47 patients of acquired heart disease and one Ebstein patient, 46 prosthetic values were implanted: 17 had M V R, 4 had A V R, 2 had M V R + A V R, and 4 had M V R + T V R and one T V R. The operative mortality was 8.S% in acquired heart disease and 17% in congenital heart disease. The follow up period was between 6 months and 6 years. There were 3 cases of late mortality in acquired heart disease and one case in congenital heart disease.

Objective: This study was designed to characterize the DNA polymorphisms of the melanocortin-1 receptor (MC1R) gene in indigenous Saudi Arabian sheep breeds exhibiting different color coats, along with individuals of the Sawaknee breed, an exotic sheep imported from Sudan. Methods: The complete coding region of MC1R gene including parts of 3' and 5' untranslated regions was amplified and sequenced from three the indigenous Saudi sheep; Najdi (generally black, n = 41), Naeimi (generally white with brown faces, n = 36) and Herri (generally white, n = 18), in addition to 13 Sawaknee sheep. Results: Five single nucleotide polymorphisms (SNPs) were detected in the MC1R gene: two led to nonsynonymous mutations (c.218 T>A, p.73 Met>Lys and c.361 G>A, p.121 Asp>Asn) and three led to synonymous mutations (c.429 C>T, p.143 Tyr>Tyr; c.600 T>G, p.200 Leu>Leu, and c.735 C>T, p.245 Ile>Ile). Based on these five SNPs, eight haplotypes representing MC1R $E^d$ and $E^+$ alleles were identified among the studied sheep breeds. The most common haplotype (H3) of the dominant $E^d$ allele was associated with either black or brown coat color in Najdi and Sawaknee sheep, respectively. Two other haplotypes (H6 and H7) of $E^d$ allele, with only the nonsynonymous mutation A218T, were detected for the first time in Saudi indigenous sheep. Conclusion: In addition to investigating the MC1R allelic variation in Saudi indigenous sheep populations, the present study supports the assumption that the two independent nonsynonymous Met73Lys and Asp121Asn mutations in MC1R gene are associated with black or red coat colors in sheep breeds.

Breνibacterium divaricatum FERM 5948 균주로 부터 Bdi I 제한효소를 ammonium sulfate분획, DEAE-cellulose chroma tograph 그리고 heparin agarose chromatograph 방법을 거쳐 부분정제하여 그 효소적 특성을 관찰하였다. 분리한 Bdi I 제한효소는 pBR 322와 ${\lambda}$ DNA를 이용하여 인지부위를 알아본 결과 5' ATCGAT3'을 인지하는 Cia I과 isoschizomer였다. 또한 CIa I 으로 자른 ${\lambda}$ DNA가 Bdi I 으로 자른 pBR 322에 클로닝 됨으로 보아 Bdi I 제한효소는 T와 C사이를 잘라(5' AT CGAT 3') 5' pGG를 가지는 cohesive end로 만듬을 알 수 있었다. 이 효소의 최적활성온도는 $37^{\circ}C$ 였고 50 - 100 mM의 NaCl 농도에서 활성이 높았으여 150 mM이상의 농도에서는 활성이 저해되었다.

From January to March in 1979 and 1982, the vaccination rate of B.C.G., D.P.T and Sabin with 392 infants who were registered at M.C.H. room in a Health Center in Seoul were as follows: 1 There were no specific relations between the sex and the vaccination for B.C.G., D.P.T. and Polio. 2. In 1982, the younger the mother's age was, the higher the vaccination rate for B.C.G. was. For the D.P.T. and Polio the rate of above 35 year group was the highest but the completion rate of the vaccination and the regular vaccination rate were the highest in the age of 30-34 year group. 3. In 1982. the higher the educational levels of tile mother were, the higher the vaccination rates for B.C.G., D.P.T. and Polio were. 4. The vaccination rate for B.C.G. within a month after birth was the highest in Salaried laborer group. The completion rate of the vaccination and regular vaccination rate for D.P.T. add Polio were also the highest in salaried laborer group. 5. In 1982, the rates of all vaccination for B.C.G. were tile highest in the first child. The completion rate of the vaccination and regular vaccination rate for D.P.T and Polio were also the highest in the first child in 1982.

우리나라 전통장류를 건염햄 제조에 접목한 건염햄의 제품을 개발하기 위해 염지과정에서 첨가한 고추장과 된장이 건염햄 품질에 미치는 영향을 조사하고자 실시하였다. 천일염(C), 천일염+고추장(T1), 천일염+된장(T2)을 한우의 반힘줄모양근(m.emitendinosus)의 표면에 골고루 발라주고 세척한 한우 대장에 충진한 후 75일 동안 건조 및 발효시켰다. 한우 반힘줄모양근 건염햄 품질을 조사한 결과, 건염햄 수분함량은 46.45-48.04% 수준으로 유의적인 차이는 없었다. T1은 모든 처리구 중에서 pH가 가장 낮았고 T2는 WHC가 가장 낮았다(p<0.05). 기계적 육색 측정에서 C가 $a^*$와 $b^*$가 전통장류 처리(T1, T2)보다 높았으나(p<0.05), $L^*$은 유의적인 차이가 없었다. 조직감에서 T1은 C보다 탄력성이 유의적으로 낮았다(p<0.05). 관능평가 결과 모든 처리구에서 유의적인 차이가 없었고 C는 제품색과 향미가 높은 점수를 받은데 반해, T1은 높은 맛, 짠맛, 그리고 전체적 기호도가 다른 처리구에 비해 높았다.

For µ = (µ₁, …, µ_t) (µ_j > 0), ξ = (z₁, …, z_t, w) ∈ ℂ^n₁ × … × ℂ^n_t × ℂ^m, define $${\Omega}({\mu},t)=\{{\xi}{\in}\mathbb{B}_{n_1}{\times}{\cdots}{\times}\mathbb{B}_{n_t}{\times}\mathbb{C}^m:{\parallel}w{\parallel}^2 where $\mathbb{B}_{n_j}$ is the unit ball in ℂ^n_j (1 ≤ j ≤ t), C(χ, µ) is a constant only depending on χ = (n₁, …, n_t) and µ = (µ₁, …, µ_t), which is a special type of generalized Cartan-Hartogs domain. We will give some sufficient and necessary conditions for the boundedness of some type of operators on L^p(Ω(µ, t), ω) (the weighted L^p space of Ω(µ, t) with weight ω, 1 < p < ∞). This result generalizes the works from certain classes of generalized complex ellipsoids to the generalized Cartan-Hartogs domain Ω(µ, t).

홀수인 소수 p와 n=4k, 그리고 $d=((p^2k+1)/2)^2$에 대해서, 주기가 $p^n-1$인 p-진 m-수열 s(t)에 대해서 $(p^{2k}+1)/2$개의 서로 다른 decimated 수열들 s(dt+1), $0{\leq}l<(p^{2k}+1)/2$가 존재한다. 이 논문에서는 s(t)와 s(dt+l), $0{\leq}l<(p^{2k}+1)/2$ 사이의 상호상관 값이 $\{-1,-1{\pm}\sqrt{p^n},-1+2\sqrt{p^n}\}$과 같음을 보이고, 상호 상관 값의 분포를 유도하였다.

The present study aimed to investigate the effects of skin care foods on the synthesis of pro-collagen type I C peptide and suppression of matrix metalloproteinase (MMP)-1 secretion through an in vitro study using fibroblasts (Hs68 cells) and keratinocytes (HaCaT cells). Among the three skin care foods developed in this study, three beans cookie and avocado yoghurt influenced the production of pro-collagen type I C peptide and suppressed MMP-1 secretion; however, tiger nut Galsu drink did not exhibit these effects. All skin care foods, including three beans cookie and plain yoghurt ($50{\mu}g/mL$, p<0.001) influenced the suppression of MMP-1 in addition to other commercially available breast milk production support foods examined, such as Heath Heather ($50{\mu}g/mL$, p<0.001), Happy Mama ($50{\mu}g/mL$, p<0.01), BioLys ($50{\mu}g/mL$, p<0.001), Enfamama ($25{\mu}g/mL$, p<0.0001), and Pregnagen ($25{\mu}g/mL$, p<0.001). Avocado fruit yoghurt ($25{\mu}g/mL$, p<0.05), avocado fruit jam yoghurt ($50{\mu}g/mL$, p<0.01), Enfamama ($100{\mu}g/mL$, p<0.05), and Pregnagen ($100{\mu}g/mL$, p<0.05) influenced the production of pro-collagen type I C peptide and suppressed MMP-1 secretion. This result indicates that only avocado jam yoghurt significantly influenced both the prevention of skin keratinization and acceleration of recovery of skin fibrous structure. Therefore, avocado is a favorable ingredient for nutrition-balanced dietary foods or an essential ingredient in products for revitalization of human skin.

In this paper, we construct explicitly an infinite family of primes P with h^±_P ≡ 0 (mod q^{deg P}), where h^±_P are the plus and minus parts of the divisor class number of the P-th cyclotomic function field over 𝔽_q(T). By using this result and Dirichlet's theorem, we give a condition of A, M ∈ 𝔽_q[T] such that there are infinitely many primes P satisfying with h^±_P ≡ 0 (mod p^e) and P ≡ A (mod M).

흰목이균, 공생균, 혼합균(흰목이균과 공생균)의 xylanase 생산 최적 탄소원은 xylose이었고 흰목이균, 공생균의 질소원은 $KNO_3$, 혼합균의 질소원은 $(NH_4)_2SO_4$이었다. Xylanase 생산 최적 배양일수는 흰목이균과 혼합균은 5일, 공생균은 6일이었으며 최적온도는 흰목이균과 공생균이 $40^{\circ}C$, 혼합균이 $45^{\circ}C$이었다. Xylanase 생산 최적 pH는 흰목이균과 공생균이 pH 6.0, 혼합균이 pH 7.0이었으며, 금속이온의 영향은 흰목이균에서는 $Hg^{2+}$, 혼합균에서는 $Pb^{2+}$를 제외하고는 금속이온이 저해적으로 나타났다. 흰목이균, 공생균, 혼합균의 xylanase 열안전성은 $50^{\circ}C$까지 80% 이상 안정하였으며, 기질(Birchwood) 특이성에 관해서는 Birchwood로부터의 xylan이 가장 활성이 높았다. 흰목이균, 공생균, 혼합균의 xylanase 기질농도는 20mg/ml, 반응시간은 45분까지 활성이 급속히 상승하다가 그후 매우 완만한 반응속도를 나타내므로서 이를 기초로 하여 Km값을 얻은 결과, 흰목이균은 $6.25{\times}10^{-5}\;M$, 혼합균은 $5.2{\times}10^{-2}\;M$, 공생균은 $5.6{\times}10^{-2}\;M$로 흰목이균, 혼합균, 공생균 순으로 효소 기질과의 친화력이 약하였다.
