The purpose of this research was to study the chemical compositions of pork for crossbred pig (female, 198 days old $102{\sim}118kg$) that were fed with tangerine byproduct from pregnancy through the whole rearing period. The samples for this study consisted of the pork from give the number of control pigs not fed with tangerine byproduct($T_0$), and the pork from give the number of study pigs fed with 8% tangerine byproduct during the whole breeding period, from the early pregnancy through the young, growing and finishing periods ($T_1$). Backfat thickness of the crossbred pigs was significantly decreased by feeding tangerine byproduct (p<0.05). The proximate composition, minerals, total amino acid, saturated fatty acid vs. unsaturated fatty acid and vitamin $B_2$ contents of loins were not significantly different among $T_0\;and\;T_1$, (p>0.05). Although those differences were not significant statistically, the tangerine byproduct tended to increase the amount of vitamin $B_1$, and decrease the crude fat and cholesterol contents.

To utilize citrus byproducts for animal feeds two different silages were made 1) using citrus peel 2) using citrus pulp mixture. The experimental design included 12 treatments, six for citrus peel silage and six for citrus pulp mixture silage, then treatments were allocated according to sun-drying and urea, barley straw and NaOH treated straw additions. Chemical composition, pH, organic acid and NBDMD were examined and treatments compared. Sun-drying (3 days) citrus waste reduced the moisture content by 6-10%. Addition of barley straw reduced the moisture content of the two silages by 4-8%. The content of protein was increased 1.25-1.63% by the urea addition of 0.6% of the silage weight. Crude fiber was increased 4-5% by the addition of 8-10% barley straw, and also increased 7-8% by the addition of 16-21% barley straw. But the change in the other ingredients by the addition of barley straw was not found, except NFE wait decreased. The pH of the non-treated silage was 3.4-4.7, and that was increased by the addition of urea and NaOH. The content of organic acid was changed by the addition of urea as follows: (1) the content of lactic acid was lowered, and (2) L.A./T.A. was decreased. But by the addition of 8-10% barley straw by the silage weight, the content or lactic acid was increased and the standard of L.A./T.A. was heightened. On the contrary, it showed the tendency of decreasing in the case of the addition of 16-20% barley straw. The range of NBDMD of raw citrus byproducts was 79.64-81.11%. That of the citrus byproducts silage was increased by the addition of urea (84.16-88.08%), and decreased by the addition of barley straw (62.4-73.16%). The addition of urea and alkali treated straw significantly increased digestibility especially in pulp mixture silage but had the reverse effect on silage quality.

Twnty-four weaners (average weight, 31 Kg) were fed for 73 days on a ration which included 0%, 5%, 10% and 15% dried citrus peel. Daily body weight gain was T_0 ; 0.804Kg, T₁ ; 0.859Kg, T₂ ; 0.874Kg, T₃ ; 0.794 Kg and daily feed intake was T_0; 2.64Kg, T₁ ; 2.85Kg, T₂ ; 2.93Kg and T₃ ; 2.74Kg. The feed intake increased up to the 10% substitution level but decreased at the 15% level. This tencency was more pronounced during the fattening than growing period. The increase in dried peel substitution levels reduced backfat thickness; increased carcass length; and widens loin eye area and generally improves carcass quality. Utilization of DM and NFE was highest in the 10% dried peel substitution level and protein was highest in the 5% substitution level. With increasing substitution levels the digestibility of crude fiber improved. From the data collected on body weight, feed intake, digestibility and carcass quality it is recommended that 10% dried citrus peel substitution is the optimum level. However under certain conditions it might be possible to increases the substitution level up to 15%.

양승주(Seung Ju Yang),김기랑(Kirang Kim),황지윤(Ji-Yun Hwang) 한국식품영양과학회 2015 한국식품영양과학회지 Vol.44 No.7

본 연구는 서울시 25개 자치구 중 2013년 아침밥 클럽으로 선정된 10개교 고등학교에 재학 중인 학생을 대상으로 2013년 아침밥 클럽 사업의 효과를 평가하였다. 사전조사와 사후조사 모두 응답한 식생활 및 학교생활 조사 대상자는 315명, 24시간 회상법에 응답한 대상자는 64명, 비만도 조사에 참여한 대상자는 124명으로 그 결과는 다음과 같다. 아침밥클럽 프로그램의 중재 후 아침식사 섭취 빈도가 증가하였으며 중재 후 38.3%, 35.7%, 17.1%의 대상자에서 각각 아침식사, 과일류, 우유류의 섭취가 주당 5회 이상으로 증가했다. 1일 식사기록법을 통해 학생들의 식품 및 영양소 섭취실태의 중재 전후 차이를 비교한 결과 아침밥 클럽 중재 이전보다 아침밥 클럽 중재 이후 곡류, 버섯류, 과일류 섭취량이 유의하게 증가했으며 난류, 유지류 섭취량이 유의하게 감소했다. 영양소는 에너지, 식물성 단백질, 탄수화물, 식이섬유, 식물성 철, 칼륨, 아연, 비타민 B1, 비타민 B6, 나이아신, 비타민 C 섭취량은 증가했으며 콜레스테롤 섭취량은 감소하였다. 학교생활에 대한 조사에서는 ‘하루의 생활을 더 편하고 즐겁게 시작하는 편이다’, ‘하루의 생활을 건강하게 시작하는 편이다’ 문항 점수가 유의하게 증가했다. 아침밥클럽은 청소년에게 필요한 아침식사를 제공해줘서 식습관과 식이섭취 상태를 개선할 뿐만이 아니라 학교생활에서도 개선을 보여 아침밥 이상의 효과를 가져온다는 측면에서 효과적인 프로그램이라고 할 수 있으며 향후 지속적인 프로그램이 서울시에 확산된다면 청소년기의 영양 상태와 학교생활 전반적인 상태에 개선을 가져올 수 있음을 시사한다. The adolescent period, during which physical, spiritual, and physiological growth and development occurs, is important for the development of healthy dietary habits. Particularly, eating a regular breakfast improves eating habits and school life in adolescents but few studies have investigated the effects of eating breakfast on these outcomes. Therefore, this research was performed to investigate the effects of eating a regular breakfast provided by the ‘Breakfast Club Program’ on eating behaviors and school life. A total of 315 high school students were recruited for the program from 10 high schools in nine districts among 25 districts in Seoul during August to December of 2013. The average age was 17.8±0.8 years and 38.1% of students were females. Based on 315 subjects, 38.3%, 35.7%, and 17.1% increased their intakes of breakfast (P=0.001), fruit (P=0.033), and milk (P<0.001) up to 5∼7 times per week, respectively. The intake frequency of fruit (P<0.001) and eating breakfast (P<0.001) increased noticeably after program participation. Based on 64 students performing dietary record, intakes of cereals (P<0.001), mushrooms (P=0.027), and fruits (P=0.002) increased while intakes of eggs (P=0.001) and fat and oils (P=0.019) decreased after the program. Consumption of energy (P=0.004), plant protein (P=0.012), carbohydrates (P<0.001), dietary fiber (P=0.026), iron from plant sources (P=0.009), potassium (P=0.043), zinc (P=0.013), vitamin B₁ (P=0.043), and vitamin C (P<0.001) increased whereas intake of cholesterol (P=0.002) decreased. Regarding school life, the score for ‘comfortable and cheerful starting of a day’ (P=0.001) and ‘healthy starting of a day’ (P<0.001) increased significantly. This study indicates that a regular ‘Breakfast Club Program’ may establish healthy eating habits and school life in teenagers.

기혼여성의 노동공급행태분석

양승주(Seung-ju Yang) 한국인구학회 1995 한국인구학 Vol.18 No.1

본 논문은 기혼여성의 경제활동 참가와 경제활동 참가 이후의 노동시간 공급을 결정짓는 요인을 분석하고, 그러한 노동공급행태의 시기적 변화를 살펴보았다. 이에 의하면, 학력이 높을수록 오히려 경제활동에 참가할 확률이 떨어지며, 6세 미만 자녀가 없을수록, 타소득수준이 낮을수록 경제활동 참가확률이 높게 나타난다. 미국의 경우 임금상승이 기혼여성 노동공급증가의 주요한 원인이라는 결론이 실질적으로 모든 연구에서 반복되어 왔으나 한국의 경우 실질임금수준은 크게 상승하지 않았음에도 불구하고 기혼여성의 노동공급이 이보다 빠른 속도로 증가했다. 그러나 1992년 분석결과에서 기혼여성의 취업구조가 다소 변화하고 있음을 확인할 수 있다. 무엇보다 시장임금수준이 높을 것으로 기대되는 여성일수록 경제활동 참가확률이 높아지는 경향이 뚜렷하게 나타난다는 사실이 1985년과 비교해 주요한 특징을 이룬다. 그러한 변화는 학력이 경제활동에 미치는 음의 효과가 여전하고 노동시간으로 본 노동공급이 시장임금의 변화에 영향을 받지 않는 것으로 나타난 점에서 상당히 완만하게 진행되고 있음을 알 수 있다.

토종닭 계란의 성분조성에 미치는 감귤부산물 급여의 영향

양승주(Seung-Ju Yang),정인철(In-Chul Jung),문윤희(Yoon-Hee Moon) 한국식품영양과학회 2008 한국식품영양과학회지 Vol.37 No.7

본 연구는 감귤부산물을 급여한 토종닭 계란의 성분조성에 미치는 영향을 파악하기 위하여 실시하였다. 토종닭 계란은 감귤부산물을 급여하지 않은 것(T0구), 그리고 감귤부산물을 4% 급여한 것(T1구)으로 나누어 각각 54수씩 3반복 사육하고 29∼30주령에 산란한 것을 시료로 하였다. 난백과 난황의 일반성분, 구성아미노산 총량, 유리아미노산 총량은 모두 T0구 및 T1구 사이에 유의적 차이를 보이지 않았다. 난황의 무기질, 비타민 및 xanthophyll 함량은 모두 T0구 및 T1구 사이에 유의적 차이를 보이지 않아서 감귤부산물 급여 영향이 없었다. 그러나 난황의 콜레스테롤 함량은 T0구의 1,207 ㎎/100 g보다 T1구의 1,168 ㎎/100 g이 유의적으로 낮으며 난백의 유리아미노산 중 L-glutamic acid 함량은 T0구의 39.22 ppm에 비하여 T1구의 58.54 ppm가 높게 나타났다(p<0.05). 그러므로 감귤부산물은 양계사료에 첨가하여 토종닭에 급여할 수 있으며 이는 효율적인 감귤부산물 처리 방안이 될 수 있겠다. In this study, the effects of feeding citrus byproducts on nutritional properties of Korean native chicken eggs were investigated. Two samples of Korean native chicken eggs were used for this study: T0 (Eggs of chickens that were not fed with citrus byproducts until they became 30 weeks old) and T1 (Eggs of chickens that were fed with 4% citrus byproducts when they were between 17 and 30 weeks old). There was no statistically meaningful difference between T0 and T1 in terms of various properties, such as general components of egg albumen and yolk, total structural amino acid, and total free amino acid. Also, no significant difference was noticed between T0 and T1 in terms of various components of egg yolk, such as amount of mineral, vitamin, and xanthophyll, which showed that those components are not affected by citrus byproducts. However, the amount of cholesterol of egg yolk for T1 was 1,168 ㎎/100 g, which was significantly lower than that for T0 which was 1,207 ㎎/100 g (p<0.05). The amount of L-glutamic acid, one of the free amino acids, of the egg albumen was 39.22 and 58.54 ppm for T0 and T1, respectively. The results of this study show that citrus byproducts can be used for the feed for Korean native chicken by adding them to general feed.
