This experiment was conducted to compare the nutritive values of locally produced oil meals for egg-type starters from birth to 6 weeks of age. Six hundred white Loghorn chickens of Hisex strain were devided into two groups i.e. group A (partial substitution for soybean lil meal) and group B(complete substitution for soybean oil meal). The group A and B were splited into 5 treatments, namely soybean oil meal (SBOM), perilla oil meal (POM), sesame oil meal (SOM), rapeseed oil meal (ROM) and corn gluten meal (CGM), respectively. The results obtained are summarized as follows. 1. The protein contents of CGM, SEOM, SOM, POM and ROM used in this experiment were 68.79, 44.33, 40.49, 39.16 and 32.25%, respectively. The methionine content of SEOM(0.53%) was found to be the lowest and of CGM (1.45%) was the higest. On the other hand, the lysine content of SOM(0.67%) was lowest and that of SBOM (2.06%) was the highest. 2. The body weight gains of CGM and SBOM treatment in the group A were higher than other treatments and that of SOM treatment was the lowest (P$lt;0.01), as were the case in the group B. The feed intake and feed efficiency showed the same tendency as the body weight gain. 3. It was found that there were no differences in nutrients utilizability among treatments.

정정수(Jung-Soo Chung),김영식(Young-Sik Kim),장지웅(Ji-Woong Jang),노종선(Jong-Seon No),정하봉(Ha-Bong Chung) 한국통신학회 2008 韓國通信學會論文誌 Vol.33 No.11C

[1]에서 LCZ 수열군의 2배 확장을 제안하였다. 본 논문에서는 [1]에서의 2배 확장방법을 일반화하는 새로운 확장방법을 제안한다. 이 생성방법을 사용하면 인수가 (N,M,L,ε)인 q진 LCZ 수열군은 인수가(pN,pM,p「(L+1)/p」-,pε)인 q진 LCZ 수열군이 된다. 이 때, p는 소수이고 p는 q의 약수다. 특히 L≡p-1modp 일 때, 확장된 q진 LCZ 수열군의 인수는 (pN,pM,L,pε)이 된다. In this paper, a new extending method of q-ary low correlation zone(LCZ) sequence sets is proposed, which is a generalization of binary LCZ sequence set by Kim, Jang, No, and Chung. Using this method, q-ary LCZ sequence set with parameters (N,M,L,ε) is extended as a q-ary LCZ sequence set with parameters (pN,pM,p「(L+1)/p」-1,pε), where p is prime and p|q.

The current study was conducted to determine the effects of high oil com(HOC) on carcass traits and pork quality as well as fatty acid composition, and cholesterol concentrations of loin muscle. Total 104 pigs(Barrow; 52, Gilts; 52) were fed diets containing typical com plus animal fat(control) or high oil corn(HOC) replacing typical corn and animal fat for the final 85 days before slaughter. There were no differences in carcass traits and pork quality between pigs fed HOC diet and control diet. The proportion of polyunsaturated fatty acids of loin muscle and loin fat from pigs fed HOC-diets was higher than that of pigs fed by regular com diet(P$lt;0.05). The cholesterol concentration of loin muscle of HOC-diet pigs tended to be lower than that of the control diet pigs.

This experiment was conducted to compare the nutritive values of locally produced oil meals for egg-type growers from 6 weeks to 21 weeks of age. Six hundred White Leghorn chickens of Hisex strain were devided into two groups, i.e. group A (partial substitution for soybean oil meal) and group B (complete substitution for soybean oil meal). The group A and B were splited into 5 treatments, namely, soybean oil meal (SBOM), perilla oil meal (POM), sesame oil meal (SOM), rapeseed oil meal (ROM) and corn gluent meal(CGM), respectively. The results obtained are summarized as follows. 1. There were no differences in body weight gain, feed intake and feed efficiency during the growing period of 6-21 weeks among treatments. The body weight gains obtained during the total growing period including the starter period (Exp` 5) of CGM, SBOM, POM, SOW and RoM fed chicks were 1604.0, 1603.0, 1582.7, 1542.6 and 1513.6g in the group A and 1578.8, 1568.3, 1518.8, 1476.2 and 1484.6g in the group B, respectively. The mean values of body weight gains during the total growing period in the group A and B were 1569.1g, 1525.3g and of feed efficiency in the group A and B were 7.08, 7.25, respectively. 2. No differences in nutrients utilizability during the growing period of 6-21 weeks was observed among treatments. It was found that the rate of nitrogen retention was somewhat decreased gradually toward the maturity of chicks progressed.

This experiment was conducted to compare the nutritive values of locally produced oil meals for laying hens from 21 weeks to 46 weeks of age. Four hundred White Leghorn hens of Hisex strain were divided into two groups, i.e. group A (partial substitution for soybean oil meal) and group B (complete substitution for soybean oil meal). The group A and B were splited into 5 treatments, namely, soybean oil meal (SBOM), perilla oil. meal (POM), sesame of meal (SOM), rapeseed oil meal (ROM) and corn gluten meal (CGM), respectively. The results obtained are summarized as follows. 1. Hen-day egg production rate of SBOM, SOM, ROM, CGM and POM treatment was 83.2, 81.5, 81.2, 80.6 and 80.2%, respectively when these oil meals were partially substituted for soybean oil meal, and that of SBOM, CGM, POM, SOM and ROM treatment was 80.9, 80.7, 78.9, 76.4 and 76.1%, respectively when the experimental meals were completely substituted. It is clear that soybean oil meal fed chicks showed the best results in egg production. The hen-day egg mass of SBOM, CGM, POM, ROM and SOM treatment was 48.3, 46.6, 46.2, 46.1 and 46.3 g in the group A and 46.7 45.5, 45.1, 43.1 and 42.2 g in the group B, respectively. Average egg size of SBOM fed treatment was 58.1 g in the group A and 57.7 g in the group B indicating that the egg size for SBOM treatment was the largest among treatments. Data also revealed that the egg size of 56.7g for ROM treatment in the group A and 55. 2g for SOM treatment in the group B were the smallest. Somewhat more shelless eggs were produced by ROM treatment than by other treatments. In the group B, the correlation coefficiency between the body weight gains during the growing period and the hen-day egg mass during the laying period was found to be +0.91. 2. Egg yolk color was somewhat improved by feeding corn gluten meal than the other vegetable protein feeds. Egg shell was somewhat thinner for ROM treatment than other treatments. 3. In general, the body weight gain during the laying period, as was the same during the growing period, was significantly (P$lt;0.05) higher for SBOM and CGM fed chicks and lower for SOM treatment. Data indicated that the mortality for CGM treatment was highest and that for SBOM treatment was lowest. 4. When the mean values of major economic characteristics in the group A and B were summarized, it was apparent that the nutritive values of locally produced oil meals could be improved when these were used with soybean oil meal. $lt;표생략$gt;

본 연구는 insulin-like growth factor-Ⅱ(IGF-Ⅱ) 가 신생자돈과 2주령 자돈에서 분리한 지방전구세포의 증식과 분화에 미치는 영향을 구명하기 위해 수행하였다. 지방전구세포는 돼지에서 떼어낸 등지방조직을 collagenase 처리에 의해 분리했고 세포를 접종한 1일 후에 세척했다(day 0). 세포의 증식은 배양초기 2일동안 50ng/ml의 IGF-Ⅱ를 처리해서 조사했고, 분화는 배양후기 4일동안 50ng/ml의 IGF-Ⅱ를 처리해서 조사했다. IGF-Ⅱ는 신생자돈과 2주령 자돈에서 분리한 지방전구세포들의 증식을 각각 19%(P<0.01), 36% (P<.001) 촉진했고 세포의 분화 는 각각 39% (P<0.01), 9% (NS) 촉진했다. The current study was undertaken to determine the effects of insulin-like growth factor-Ⅱ (IGF-Ⅱ) on proliferation and differentiation of the preadipocytes from newborn and 2 week-old male pigs. The preadipocytes were isolated by collagenase treatment of the backfat tissue taken from the pigs and the cells were washed with DMEM/F-12 on the next day (designated day 0). To measure cell proliferation, the cells were treated with IGF-Ⅱ (50ng/ml) for two days (day 0~day 2). To measure cell differentiation, the cells were treated with IGF-Ⅱ(50ng/ml) for four days (day 2~ day 6). IGF-Ⅱ stimulated proliferation of the preadipcytes from newborns and 2 week-old pigs by 19% (P<0.01) and 36% (P<0.01), respectively. IGF-Ⅱ stimulated cell differentiation of the preadipocytes from newborn and 2-week old pigs by 39% (P<0.01) and 9% (NS) respectively.

Sequence Diagram을 이용한 테스트 오라클 생성

정정수(Chung-Su Chung),김형호(Hyung-Ho Kim),조승모(Seung-Mo Cho),권용래(Yong-Rae Kwon) 한국정보과학회 2000 한국정보과학회 학술발표논문집 Vol.27 No.2Ⅰ

이 논문에서는 산업계의 표준으로 널리 사용되고 있는 객체 지향 시스템의 명세 언어인 UML의 sequence diagram을 이용하여 객체 지향 시스템을 검증하는 방법과 이 방법을 테스팅 오라클을 생성하는 데 사용할 수 있는 프레임웍을 제시하였다. 우리는 sequence diagram을 테스팅 결과의 검증에 사용하기 위하여 정형적으로 재정의 하였다. 그리고 시제 논리의 강력한 검증 능력을 사용하기 위해서 Half-Order Dynamic Temporal Logic(HDTL)이라 불리는 새로운 시제 논리를 정의하였고 sequence diagram을 HDTL 논리식으로 변환시키는 의미 함수(semantic function)를 정의하였다. HDTL에서 오토마톤을 생성하기 위해서 Tableau 방법을 변형하여 적용시켰다. 이 결과 생성된 오토마톤은 이상 상태(anomaly), 즉 sequence diagram에 표현되지 않은 사건(event)의 발생을 검색하는 오라클로 사용할 수 있다. 테스팅의 결과를 수작업으로 검증하는 것은 매우 어렵고 오류가 발생하기 쉬운 작업이므로 제안한 방법은 유용하게 사용될 수 있다.

웅성호르몬이 암수 돼지 지방전구세포의 분화에 미치는 영향

정정수(Chung Soo Chung),김원영(Won Young Kim) 충북대학교 동물생명과학연구소 2009 동물생명과학연구 Vol.2 No.-

본 연구는 웅성호르몬이 돼지 지방전구세포의 증식과 분화에 미치는 영향을 구명하기 위해서 수행하였다. 지방전구세포는 암, 수 신생자돈의 등지방조직을 collagenase 처리에 의해서 분리했다. 10<SUP>-8</SUP>M과 10<SUP>-7</SUP>M의 testosterone 과 19-nortestosterone을 4일(증식측정) 또는 6일(분화측정)동안 배양중인 지방전구세포에 처리했다. 이들 호르몬(10-8M과 10-7M 모두)은 암, 수 돼지 지방전구세포의 증식에는 아무런 작용이 없었으나, 세포의 분화는 촉진하였다. 촉진 작용에는 호르몬 간에 그리고 성별간에 차이가 없었다. The current study was undertaken to determine the effect of male sex steroid hormones on proliferation and differentiation of pig preadipocytes. The preadipocytes were isolated from the backfat of new-born female and male pigs by collagenase digestion.10<SUP>-8</SUP>M and 10<SUP>-7</SUP>M testosterone and 19-nortestosterone were treated to the preadipocytes in culture for 4 days(proliferation) or 6 days(differentiation). These hormones (10<SUP>-8</SUP>M and 10<SUP>-7</SUP>M) did not affect proliferation of pig adipocytes from either female or male backfats, however the hormones stimulated differentiation of pig preadipotyes. There was no difference in increasing differentiation among the hormones and between the female and male pigs.
