이 연구는 의류제품을 구매하는 소비자에게 구매의사 결정에 미치는 영향을 살펴보고자 하는 배경에서 시작되었다. 의류 브랜드숍 이용자를 대상으로 하여 소비자 구매의도에 미치는 영향요인을 사회적 책임활동, 관계품질, 마케팅 자극요인으로 설정하였다. 독립변수인 사회적 책임활동, 관계품질, 마케팅 자극요인과 매개변수인 구매의도간의 조절적인 영향을 주는 서비스 품질의 조절변수에 대한 영향력을 분석하였다. 또한 매개변수인 구매의도가 종속변수인 충동구매와 구매행동에 미치는 영향에 대해 분석하였다. 사회적 책임활동은 하위변수로 법률적 책임활동, 경제적 책임활동, 자선적 책임활동, 윤리적 책임활동으로 설정하였고, 관계품질은 고객신뢰, 고객몰입, 고객만족을 하위변수로 설정하였으며, 마케팅 자극요인은 하위변수로 구매요인, 제품요인, 가격요인으로 설정하였다. 탐색적인 관점에서 서비스 품질을 조절변수로 설정하여 의류산업의 사회적 책임활동 및 관계품질, 마케팅 자극요인과 구매의도 간에 조절적 역할을 검증하였다. 또한, 독립변수인 사회적 책임활동, 관계품질, 마케팅자극요인이 종속변수인 충동구매, 구매행동과의 관계에서 구매의도의 매개변수가 매개효과를 주는지 영향력을 검증하였다. 분석결과, 첫째, 사회적 책임활동의 법률적 책임활동은 소비자의 구매의도에 영향을 미치는 요인으로 분석되었으나, 경제적 책임활동, 자선적 책임활동, 윤리적 책임활동은 구매의도에 영향을 미치지 않는 요인으로 분석 되었다. 둘째, 관계품질의 고객신뢰, 고객몰입, 고객만족은 소비자의 구매의도에 영향을 미치는 변수로 분석되었다. 고객신뢰, 고객몰입, 고객만족 등과 같은 변수들은 전통적으로 소비자 행동에 영향을 미치는 변수들로 많은 연구에서 제시되고 있는데, 의류산업과 같은 소비재산업의 경우에도 이러한 변수들이 구매의도나 구매행동, 그리고 충동구매에 영향을 주는 아주 중요한 변수라는 것을 알 수 있었다. 셋째, 마케팅 자극요인에서 제품요인과 가격요인은 구매의도에 영향을 미치는 변수로 분석되었지만, 구매요인은 구매의도에 영향을 미치지 않는 요인으로 분석되었다. 이 결과는 다른 독립변수들과 마찬가지로 여러 소비재 산업에도 영향을 미치는 것을 알 수 있다. 넷째, 탐색적인 관점에서 의류제품 브랜드숍의 서비스 품질을 조절변수로 설정하여 사회적 책임활동, 관계품질, 마케팅 자극요인과 구매의도 간의 조절적인 역할을 분석한 결과, 마케팅 자극요인의 구매요인만 조절적인 역할을 하고 있는 것으로 분석되었다. 다섯째, 대부분의 독립변수의 경우 구매의도에 매개효과가 충동구매 및 구매행동에 영향이 있는 것으로 나타났고, 윤리적 책임활동과 그룹변수인 사회적 책임활동은 충동구매와의 관계에서 매개효과가 없는 것으로 나타났다. 마지막으로, 독립변수인 사회적 책임활동, 관계품질, 마케팅 자극요인에 영향을 받은 구매의도는 충동구매와 구매행동에 영향을 미치는 것으로 분석되었다. 따라서, 이 연구에서는 연구 결과를 토대로 독립변수인 사회적 책임활동, 관계품질, 마케팅 자극요인은 조절변수인 서비스 품질에 큰 영향을 받진 않지만, 구매행동에 유의한 정(+)의 영향을 미치는 것으로 검증되었다. The background of this study is to identify the impact of consumers purchasing clothes on determining the intention for purchase. The users of the clothing brand shops were targeted to set the impact factors on the intention for purchase as social responsibility, relationship quality and marketing stimulation factor. The impact of service quality which has controlled impact between the independent variables of social responsibility, relationship quality and marketing stimulation factors, and the parameter of intention for purchase on moderating variables was analyzed. In addition, analysis was made on the impact of the parameter of intention for purchase on the dependent variables of impulse buying and purchasing behavior. In the social responsibility, the sub-variables were set to be legal responsibility, economic responsibility, charitable responsibility and ethical responsibility, and in the relationship quality, customer trust, customer commitment and customer satisfaction were set as the sub-variables. In the marketing stimulation factor, purchase factors, product factors and price factors were set as the sub-variables. Service quality was set as the moderating variable in the exploratory perspective to verify the regulatory role between the social responsibility, relationship quality, marketing stimulation factor and intention for purchase in the clothing industry. In addition, the impact was verified on whether the parameters of intention for purchase have mediating effect in the relationship between the independent variables of social responsibility, relationship quality and marketing stimulation factor and the dependent variables of impulse buying and purchasing behavior. As a result of the analysis, first, the legal responsibility in the social responsibility was analyzed as the factor having impact to the intention for purchase by the consumer, but economic responsibility, charitable responsibility and ethical responsibility were analyzed as the factors not having impact to the intention for purchase. Second, customer trust, customer commitment and customer satisfaction in the relationship quality were analyzed to be the variables having impact to the intention for purchase by the consumer. Variables such as customer trust, customer commitment and customer satisfaction, etc. are provided in many studies as the variables that traditionally have impact to the consumer behavior, but these variables were identified to be very important variables having impact to the intention for purchase, purchasing behavior and impulse buying also in the consumer goods industry such as the clothing industry. Third, product factor and price factor in the marketing stimulation factor were analyzed as the variables having impact to the intention for purchase, but purchase factor was analyzed as the factor not having impact to the intention for purchase. Through this result, it was verified as having impact also to various consumer goods industry like other independent variables. Fourth, as a result of setting the service quality of the clothing brand shop as the moderating variable in the exploratory perspective to analyze the regulatory role between the social responsibility, relationship quality and marketing stimulation factor with intention for purchase, only the purchase factor in the marketing stimulation factor was analyzed to have regulatory role. Fifth, most of the independent variables showed that mediating effect had impact to the impulse buying and purchasing behavior on the intention for purchase, and ethical responsibility and group variable of social responsibility were shown to have no mediating effect in the relationship with the impulse buying. Lastly, the intention for purchase having impact from the independent variables of social responsibility, relationship quality and marketing stimulation factor was analyzed to have impact to the impulse buying and purchasing behavior. In conclusion, the result of this study showed that independent variables of social responsibility, relationship quality and marketing stimulation factor did not have significant impact to the moderating variable of service quality, but it was verified to have positive (+) impact to the purchasing behavior.

이형호 건국대학교 대학원 2013 국내석사

본 연구의 목적은 산패된 식물성 유지 사용이 산란계 성적에 미치는 영향을 조사하고 이에 대한 비타민 E와 폴리페놀을 함유한 천연물의 항산화 작용이 산란율, 난중, 일당 난 생산량 등의 생산성 지표, Haugh unit, MDA, 난각두께, 난각강도, 난황색 등의 난 품질 지표와 혈액 내 GOT, GPT, SOD 및 장내 균총 등에 미치는 영향을 알아보고자 실시하였다. 180수의 61주령 Lohmann Brown계통의 실용계 암컷에게 신선 유지를 1.5% 급여한 군(PC)과 산패 유지를 1.5%씩 급여한 뒤 항산화제를 무급여한 군(NC), 비타민 E를 200 ppm 급여한 군(T1). 비타민 E와 천연항산화제(Cabanin-CSD®)를 각각 100 ppm 씩 총 200 ppm급여한 군(T2) 및 천연항산화제(Cabanin-CSD®)만 500 ppm 급여한 군(T3)으로 나누어 6주간 사료를 급이하였다. 사료 섭취량과 난 생산성은 매일 기록하였으며 할란 검사는 주 단위로 실시하였다. 실험 종료일에 수거한 계란을 1일, 7일, 15일간 저장 한 후 Haugh unit를 측정하였고 사양실험 종료 시 각 공시계로부터 혈액을 채취하여 GOT, GPT 및 SOD 활성을 조사하였다. 마지막으로 cecum sample을 채취하여 장내 균총을 조사하였다. 산패 유지 및 항산화제 첨가에 따른 산란율, 난중 및 사료섭취량에서는 큰 차이가 없는 것으로 나타났다. 반면 산패 유지와 항산화제를 동시에 첨가한 군에서 일당 난 생산량의 유의한 개선이 관찰되었으며 (P<0.05), 특히 비타민 E와 천연 폴리페놀을 동시에 첨가한 처리구에서는 기타 처리구 대비 가장 긍정적인 결과가 나타났다. 계란의 품질과 관련한 난황색, 난각 두께 및 난각 강도에서는 통계적으로 유의한 차이가 없었으며 수치상으로도 큰 변별력을 나타내지 아니하였다. 저장시간의 경과에 따른 계란의 보존성을 1일, 7일, 15일 경과 후의 Haugh unit로 조사하였을 때 산패 유지에 항산화제를 첨가한 군에서 통계적으로 유의한 차이를 나타내며 수치가 개선되는 결과를 나타내었다. 혈청 내 GOT 농도에서는 처리구간에 통계적으로 유의한 차이를 나타내었으며 산패 유지만 급여한 NC구에서 가장 높은 수치가 관찰되었고 산패 유지에 비타민 E와 천연 폴리페놀을 함께 급여한 T2구에서 가장 낮은 수치를 나타내어 산패 유지의 첨가로 높아진 간 내 독성을 항산화제가 신선 유지만을 급여한 PC구 보다도 더 안정적으로 제어할 수 있음을 관찰할 수 있었다. SOD 유사 활성 수치에서는 산패 유지만 첨가한 NC구에 대비하여 항산화제를 첨가한 T1, T2 및 T3구에서 통계적으로 유의한 차이가 인정되었으며 산패 유지만 첨가한 처리구 대비하여 항산화제를 급여으로써 항산화 능력이 크게 개선됨을 확인할 수 있었으며 cecum 미생물 균총을 수거하여 분석한 total microbes, Lactobacilli 및 Enterococcus faecium 균수에 있어서 펀연 폴리페놀 항산화제를 첨가한 T2, T3 처리구에서 통계적으로 유의한 차이를 보이며 가장 우수한 성적이 관찰되었다. 본 연구에서는 산란계 사료 내 산패 유지의 첨가가 계란의 보존성을 떨어뜨리고 산란계의 간을 손상시키며 항산화 대응 능력을 떨어뜨리고 장내 미생물 균총에도 악영향을 끼친다는 것을 확인하였으며 항산화제의 첨가가 이러한 악영향을 완화시켜 난 품질을 유지하고 산란계의 건강한 상태를 유지하는 데 필요하다는 것을 확인하였다. 다만, 산란성적과 관련한 수치에서는 다양한 선행 연구에서도 산화된 식물성 유지의 첨가에 의한 결과가 다소 엇갈리며 본 연구에서도 산화된 식물성 유지의 급여 및 항산화제의 첨가로 인한 산란성적의 통계적 유의차를 발견할 수 없었으므로 향후 대규모 사양실험과 산란계의 연령을 고려한 추가적인 분석을 통해 보다 명확한 결과를 연구할 필요가 있겠다.

Caerulein으로 유발된 흰쥐의 급성 췌장염에 대한 銀茴蟠葱散의 효과

이형호 東新大學校 2009 국내박사

In this study we aimed to investigate the effect of EunHoeBanChongSan (EBS) on caerulein-induced acute pancreatitis (AP) by detecting oxidative stress markers and performing histopathological examination. Thirty adult male Sprague-Dawley rats were divided into five groups as follows: normal (NOR), caerulein-induced (CON), caerulein+EBS (130㎎/㎏, EA), caerulein+EBS (260㎎/㎏, EB) and caerulein+EBS (520㎎/㎏, EC) groups. Pancreatic tissues of rats from all groups were removed for apoptosis and light, and electron microscopic examination. Blood of rats from all groups were obtained for oxidative stress markers and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of superoxide dismutase (SOD) and catalase (CAT). Serum amylase, Platelet activating factor (PAF), and Interleukin-6 (IL-6) levels were determined spectrophotometrically. The ratio of pancreas/body weight was increased significantly (p<0.05) in the CON compared with NOR, but decreased significantly (p<0.05) in EA, EB, EC groups compared with CON. Caerulein administration resulted in a significant increase (p<0.05) in amylase, but EBS reduced the levels of these enzyme. The levels of Platelet activating factor (PAF) were increased in CON compared with NOR, but decreased in EA and EB groups compared with CON at 2hrs. Interleukin-6 (IL-6) levels were increased significantly in CON compared with NOR, but reduced in EA, EB, and EC groups at 24hrs groups. The SOD and catalase activities were decreased in CON, but catalase activities of EB and EC groups increased than that of CON. EBS is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue, therefore we concluded that EBS may have beneficial effects in the treatment of caerulein-induced AP.

리모델링 선호자의 의식 연구

이형호 동의대학교 대학원 2008 국내석사

지금까지 우리나라의 주택정책은 주택부족문제를 해결하기 위한 정책이 대부분이었다. 주택보급률 확대를 위해 신규주택 공급에 비중을 두어 양적 팽창을 해온 결과 전국의 주택보급률은 현재 100%가 넘는다. 이에 따라 정부도 주택정책을 신축 위주가 아닌 기존주택의 관리·개선에 역점을 두고 있고, 주택법등을 개정하여 재고주택의 관리와 운영을 중시하는 둔 주택정책을 펴고 있다. 1960년대 아파트가 등장한 이후 공동주택은 급속도로 건설되어 현재 전국의 주택보급률은 이미 포화상태에 있고, 80년대 초반까지 지어진 아파트들은 대부분 저밀도 저층 단지로 조성되어 있고, 건물의 물리적 수명은 상당시간 남아 있지만 생활수준의 향상으로 인하여 사회 경제적 수명이 다한 상태여서 주거환경 개선이 시급한 실정이다. 그러나 이제는 주택을 공급할 수 있는 방안을 연구하기 보다는 공급되어 있는 주택을 어떻게 관리해 나가야 할지 고려해야 할 시점이다. 따라서 신규 공급을 수반하는 재건축 보다는 리모델링이 현재 더 적합한 주거환경 개선 방안이라 하겠다. 부산시의 경우만 보더라도 택지부족으로 신규 주택 공급에 한계가 있을 뿐 아니라 대부분의 택지 지형이 고지대로 입지여건이 열악하여 재건축 사업이 추진되기가 무척 어려워 부산시의 경우에서도 리모델링이 재건축보다 더 적합한 주거환경 개선 방안이라 하겠다. 본 연구는 부산시 수영구에 위치한 삼익비치파트의 주거환경 개선 사업에 관한 연구다. 현재 삼익비치 아파트는 재건축과 리모델링이 동시에 추진되고 있어 주거환경 개선방안으로 재건축과 리모델링을 비교하는 좋은 표본이 될 수 있다. 현재 삼익비치아파트 3060세대 중 대부분의 사람이 재건축을 통해 주거환경을 개선하고 부수적으로 집값 상승에 따른 경제적인 수익을 생각하고 있으나 일부 주민들은 재건축에 반대하고 리모델링을 주거환경 개선의 또 다른 대안으로 생각하고 있다. 이에 본 연구는 대다수의 주민들이 재건축만이 주거환경을 개선하는데 효과적이고 큰 경제적 이득을 줄 거라는 의식이 팽배한 상황 하에, 일부의 사람들은 어떤 이유로 리모델링을 추진하려고 하는지에 관한 이유를 설문조사와 인터뷰를 통해 의식을 연구하고자 함이다. 본 연구는 1장에서는 연구의 배경과 목적을 제시했고, 2장에서는 주거환경 개선 방안 중 재건축과 리모델링에 관한 정의와 절차와 알아보았으며, 재건축과 리모델링의 장단점을 알아보았다. 또한 선행연구의 고찰을 통해 지금까지의 대부분의 리모델링·재건축 연구가 경제성과 환경성 분석에 국한되어왔다는 점을 알 수 있었다. 3장에서는 공동주택 리모델링의 사례분석 및 추진현황에 대해 논했다. 3장의 사례분석을 통해 재건축은 대부분이 세대수 증가를 통한 주거환경 개선 방식이므로 재건축 보다는 리모델링이 현재의 상황에선 더욱 합리적이라는 결론을 도출 할 수 있었다. 또한 리모델링을 통한 가격상승 기대에 대한 질문엔 부산지역 시민들의 52.2% 이상이 투자비 이상으로 아파트 가격 상승 할 수 있을 것이라는 조사와 리모델링 시행 완료 사례를 통해 리모델링이 투자성에 대한 가치도 있음을 확인 할 수 있었다. 4장에서는 부산시 수영구에 위치한 삼익비치아파트 주민들을 상대로 설문조사와 전문가 인터뷰에 대한 결과를 논하였다. 설문은 크게 리모델링시 요구사항과 리모델링에 대한 정책 그리고 리모델링에 대한 투자성에 관한 질문을 했고 중복문항을 통한 유효성 검증을 통해 결론을 도출했다. 5장에서는 4장의 설문조사 결과를 통해 현 시점에서 재건축보다는 리모델링이 주거환경 개선 방안으로 더욱 적합하다는 결론을 내렸고, 삼익비치 아파트 리모델링 선호자들의 의식적인 측면에서 보더라도 리모델링이 좋은 대안이 될 수 있음을 결론으로 도출하였다. The domestic housing market reached the limit in the quantitative expansion due to the large-scale multi-family housing supply project such as constructing 2,000,000 houses, which was started in the end of the past 1980s, thus the oversupply phenomenon has being visualized such as the unsold situation in recently a few years. Accordingly, the currently domestic housing market reached the ceiling that cannot be sustained any more only with new construction. Also, the existing multi-family housings are approaching deterioration such as a drop in function currently caused by physical characteristics and failing to cope with a rapid-changing speed in industrial development and social structure. The current multi-family housing was considerably improved the housing performance due to enhancement in life level, progress in informatization, and a change in life consciousness, and is also being increased dwellers' needs. Accordingly, in order to improve performance in the aged multi-family housing, the reconstruction and remodeling businesses are being emerged. However, as reconstruction is a concept that removes all the conventional buildings and builds newly, the problems are immanent such as the occurrence of resources extravagance according to removing structures and equipment elements still available for use, and as the consumption of unnecessary resources in the process of newly building again. Thus, at this point of time, remodeling needs to be selected as a method of improving the housing environment, rather than reconstruction. According to the recently social flow, the researches on reconstruction and remodeling are being steadily announced. However, the decision-making is unreasonable, which is just based on economical efficiency and environmental feasibility that are possessed by reconstruction and remodeling. Accordingly, this study extracted Samik Beach Apartment as sample, where is located in Suyeong-gu, Busan-si, which is being enforced simultaneously the reconstruction and remodeling, and tried to research into the cognition of those who prefer home remodeling. The majority of residents in the above sample subjects are still believing that reconstruction will bring about more economic profits rather than remodeling, and think that only reconstruction will be able to improve the aged apartment. However, through this study, it could be known that remodeling also has economic benefits more than reconstruction, and that housing environment can be improved through surveying residents' demands. In case of Samik Beach Apartment, given examining a reason that remodeling is more reasonable than reconstruction in the conscious part, not in the economic or environment aspect, Samik Beach Apartment has a very great value in the prospect right compared to other district. Given seeing on the basis of 48 pyeong, there is the price gap in more than 100 million won between the building of being seen the sea and the building of being inverse. However, when reconstruction is enforced according to the currently reconstruction regulation, the residents, who have the existing prospect right, comes to be difficult to be recognized the value of the prospect right. Samik Beach Apartment now needs to be improved the housing environment regardless of reconstruction or remodeling. However, a minority of inhabitants, who have the prospect right, shouldn't be coerced the selection of reconstruction by the logic of a majority who prefer reconstruction. That is because remodeling cannot be a good alternative plan. The contents, which were elicited in this study, are the analysis results on the corresponding specific unit buildings, thereby containing difficulty for generalization of the research results. Consequently, as for a research that will be performed in the future, a research with diverse cases will need to be progressed, which can supplement the above limitations.

Heat and momentum transport analysis of KSTAR plasmas with Charge Exchange Spectroscopy

이형호 과학기술연합대학원대학교 2013 국내박사

The plasma rotation or its shear plays an important role for the plasma confinement and stability. In general, the external momentum sources such as uni-directional NBIs are necessary to drive the plasma rotation. But, it has been frequently observed that the plasma rotation can be changed significantly without any external momentum sources. Although many experimental and theoretical researches have been dedicated to study this plasma rotation without any external momentum source, it is not fully understood yet. Still, comprehensive heat and momentum transport study are demanded to understand the physics of the plasma rotation. Since the measurement of the ion temperature and plasma rotation profiles are very necessary for the heat and momentum transport study of plasma, the charge exchange spectroscopy (CES) system has been developed for the measurement of the ion temperature and toroidal rotation profiles of the KSTAR plasmas. The KSTAR CES system which measures the C VI 5290.5 Å (n=8→7) charge-exchange spectrum signal is featured with its high time resolution of 10 ms and spatially resolved 32 channels. The spatial channels are allocated at every 5 cm in core region and 5 mm in edge region for full profile measurement. The KSTAR CES measurement has been applied to investigate the dynamics of the ion temperature and toroidal rotation profiles for various KSTAR plasmas. Heat and momentum transport analysis of the KSTAR L-mode and H-mode plasmas has been conducted along with the measured ion temperature and toroidal rotation profiles. Empirical transport analysis code has been developed for the transport analysis of the KSTAR plasmas. The quantitative comparison of the heat and momentum transport physics between the L-mode and H-mode plasmas has been achieved by the empirical transport analysis code. The detailed momentum transport study by considering inward momentum pinch and residual stress has been conducted. Finally, it has been frequently observed that the toroidal rotation speed is reduced regardless of the direction of the toroidal rotation when the on-axis ECRH heating is applied in the KSTAR plasmas. Moreover, it has been found that toroidal rotation damping is accompanied by (m, n) = (1,1) internal kink modes which are localized in the central region of the plasma very frequently. The neoclassical toroidal viscosity torque has been proposed to explain the reduction of the toroidal rotation since the neoclassical toroidal viscosity torque can be enhanced if the toroidal symmetry is broken by the internal kink modes.

이형호 단국대학교 2016 국내박사

EXPERIMENT 1: EFFECT OF NUCLEOTIDE SUPPLEMENTATION ON PERFORMANCE AND BLOOD PROFILES IN LACTATIONG SOWS AND SUCKLING PIGLETS The objective of the present study was to analyze the effect of nucleotides on reproductive performance, growth performance, fecal score, fecal microflora and blood profiles in lactating sows and their piglets. A total of 15 (LY) sows were allocated to 1 of 3 treatments with 5 replicates and the average parity was 4.13. Dietary treatments include: 1) CON: basal diet; 2) T1, CON + 0.5% nucleotide; 3) T2, CON + 1.0% nucleotide. The statistical analysis was performed using randomized design by GLM procedure. In this study, significant difference (linear) was observed among treatments, including litter size (p=0.0179), live piglet (p=0.0117), and piglet survival (p=0.0488). The BW of weanling pigs shows no significant difference observed among the treatments. The ADFI was not altered during gestation, but shows significant linear increase (p=0.0467) during lactation. The back fat thickness during weaning showed a significant effect which increased linearly (p=0.0468). The BW of piglets at wk 2 shows a significant difference quadratically (p-0.0167) among the treatment groups. Similarly in weanling, the BW of piglets showed linearly significant increase (p=0.0029). The ADG of piglets during initial stage to wk2, showed both linear (p=0.022) and quadratic (p=0.0044) significant difference among the treatment groups. Also there was a linearly significant difference from wk 2 to weanling period (p=0.0277) and total ADG (p=0.0014) among treatments. Increase in (p>0.05) fecal lactobacillus concentration (p=0.0072) and decrease in fecal E.coli concentration was found linearly (p=0.0104). The epinephrine and norepinephrine concentrations were affected by the dietary treatments and shows a linear decrease in epinephrine (p=0.0205) and norepinephrine (p=0.06163). Also significant linear decrease in the level of cortisol (p=0.0277) was observed. The results of this study demonstrate the importance of increased levels of total nucleotides in the diet of sows to improve sows and piglet performance. EXPERIMENT 2. EFFECT OF NUCLEOTIDE SUPPLEMENTATION ON GROWTH PERFORMANCE, BLOOD PROFILES AND FECAL SCORE IN WEANLING PIGS The aim of the current study was to analyze the effect of nucleotide as the dietary supplement for growth performance, blood profiles, and fecal score in the weanling pigs. A total of 120 weanling pigs [(Landrace x Yorkshire) x Duroc] with an average initial body weight (BW) of 6.29 ± 0.71 kg and 28 d of age were used in a 42 days experiment. Pigs were allotted as 5 pigs per pen and 8pen per treatment. Dietary treatments include: T1 (CON), Basal diet; WNT1, Basal diet + 0.5% nucleotide; WNT2, Basal diet + 1.0% nucleotide. The statistical analysis was performed using randomized design by GLM procedure. The initial BW was measured at d14, d28 and d42. Significant increase in BW was observed in d14 (linear, p= 0.0001; quadratic p=0.0195), d28 (linear, p=0.0003) and d42 (linear, p=<0.0001 and quadratic, p=0.0462) of the treatment groups. ADG, ADFI and G/F ratio was measured in phase I, II, III and in overall experimental periods. Among these, ADG was found to be significantly increased in phase I (p=0.0001, linear; p=0.0165; quadratic), phase II (p=0.0366, linear), phase III (p=0.0121; linear) and overall period (p=0.0001, linear; p=0.0489; quadratic). ADFI showed significant increase in phase III(p=0.0492, linear) and overall period (p=0.0215, linear). The G/F ratio was found to be significant in overall period (p=0.0398) linearly among the treatment groups. The level of epinephrine (p=0.0305), norepinephrine (p=0.0378) and cortisol (p=0.0204) were found to be significantly decreased linearly. Thus, we can think that supplementation of dietary nucleotide can affect the growth performance and blood profiles in weanling pigs. EXPERIMENT 3: EFFECT OF NUCLEOTIDE SUPPLEMENTATION IN WEANLING PIGS CHALLENGED WITH LIPOPOLYSACCHARIDE (LPS) The study aims to analyze the effect of nucleotide on growth performance, blood profiles, rectal temperature, excreta microflora and the fecal score in the weanling pigs challenged with LPS. A total of 40 pigs with an average initial body weight (BW) of 6.29 ± 0.71 kg and 28 d of age were used in a 42 days experiment in 3 different hybrid [(Landrace x Yorkshire) x Duroc ] weanling pigs. Pigs were fed 0 or 0.5% Nucleotide diet for 42 d. At 4th week, half of the pigs (n = 5) from each treatment were injected LPS intraperitoneally. Dietary treatments include: T1, Basal diet with Saline; T2, Basal diet with lipopolysaccharide; T3, Basal diet + 0.5% nucleotide with Saline; T4, Basal diet + 0.5% nucleotide with lipopolysaccharide. Pigs were allocated to 1 of 4 treatments (2 replicates per treatment; 5 pigs per pen). All data were analyzed by 2x2 factorial arrangements of treatments. The body weight in the weanling pigs did not show any improvement after the treatment. The ADFI of the weanling pigs during phase III (p=0.0364; linear and p= 0.0104; quadratic) and overall period (p=0.0463;linear) significant elevation when compared to rest of the experiment (P <0.05). The ADG of the weanling pigs showed significant difference with dietary supplementation in phase III (p= 0.0380, linear) and overall experimental period (p= 0.0123, linear). The G/F ratio of the weanling pigs shows significant improvement by the nucleotide supplementation during overall experimental period (p= 0.0276, linear). The IgG level was almost increased similarly during whole experimental period for 0.5% nucleotide supplementation group either there was LPS or saline injection when compared with 0% nucleotide supplementation. The WBC levels were found to be elevated for 0.5% nucleotide supplementation for both LPS and saline treatment when compared to 0% nucleotide supplementation for the overall experiment. The Lymphocyte levels observed to be highly elevated for 0.5% nucleotide fed group with saline injection than the rest of the treatments for the entire test period. The rectal temperature checked at 2hr, 6hr and 10hr showed significance difference (P <0.05). The excreta microflora in weanling pigs before LPS challenge showed significance for Lactobacillus (P <0.05). The fecal score in the weanling pigs gave a significant difference after the treatment on the week 4 and week 5 (P <0.05).Thus dietary nucleotide to piglets could alleviate the immunological responses to LPS challenge in the blood and show some positive response in growth. EXPERIMENT 4: EFFECT OF NUCLEOTIDE SUPPLEMENTATION ON GROWTH PERFORMANCE, NUTRIENT DIGESTIBILITY AND BLOOD PROFILES IN GROWING PIGS The aim of present study was to evaluate the effects of nucleotide supplementation on growth performance, nutrient digestibility and blood profiles in growing pigs. A total of 120 growing pigs [(Yorkshire × Landrace) × Duroc] with an average BW of 25.76 ± 1.83 kg were used. Pigs were allocated to 1 of 4 treatments by body weight and sex (3 barrows and 2 gilts per pen; 6 pen per treatment). Dietary treatments include: 1) CON: basal diet; 2) GAT1: CON + anti VS-2 Inoculate 0.5% / FMD vaccine; 3) GNT1: CON + Nucleotide 0.5% / FMD vaccine; and 4) GNT2: CON + Nucleotide 1.0% / FMD vaccine. The FMD vaccination was inoculated to all pigs on 84th day (experiment wk 2). Body weight and feed consumption were measured initially and in 6wk to monitor the average daily gain (ADG), average daily feed intake(ADFI) and gain:feed (G:F) ratio. Apparent total tract digestibility (ATTD) of DM and N were analyzed. The serum parameters (cortisol, epinephrine and norepinephrine) were measured. The statistical analysis was performed using randomized design by GLM procedure of SAS. At the beginning of the trial (initial), and at wk 6, the BW of growing pigs showed no significant differences among the treatments. During this overall periods, the ADG of growing pigs were found to be significantly increased (p=0.054), and the pigs had a higher G/F ratio in GNT groups (p= 0.025, linear). The digestibility of DM showed significant increase in GNP groups (p= 0.018, linear), when compared to control. After injection, there was a significant decrease (linear) in levels of cortisol (p=0.012) and epinephrine (p=0.011) in GNT groups. GNT groups also showed significant decrease in both cortisol (p=0.015) and epinephrine (p=0.021) when compared to GAT1. Moreover, the norepinephrine concentrations were unaffected by the dietary treatments. Therefore in our study, the nucleotide supplementation could have an effect on ADG, G/F ratio, DM, cortisol and epinephrine levels in growing pigs.
