부란중 발육계란의 수침처리가 부화율에 미치는 효과

이승규 ( Seung Kyu Rhee ) 한국축산학회 1972 한국축산학회지 Vol.14 No.2

The purpose of this study was to examine the effect of water-soaking of hen`s egg during incubation on the hatchability. The following three factors were considered important in the water-soaking: the age of embryo at water-soaking, the length of water-soaking, and the water temperature. Two experiments were carried out to determine the adequate level of each factor that may improve the hatchability. In experiment Ⅰ, a split-split plot experiment was carried out to try 2 lengths of water-soaking at 2 different water temperatures on 12th, 13th, and 14th day of incubation. The main plots were the age of embryo at water-soaking. In each main plot, there were sub-plots with 2 different lengths of water-soaking: 5 and 10 minutes. Each subplot was divided into 2 parts with water temperatures of 4℃ and 8℃. The results obtained in experiment I are as follows. (1) The differences between the ages of water-soaking were statistically significant. The water-soaking on 12th day of incubation give the best hatchability. (2) The difference between the water-soaking for 5 and 10 minutes was statistically insignificant, although the tendency was in favor of the water-soaking for 5 minutes. The difference between the water temperatures of 4℃ and 8℃ was also insignificant, but the hatchability was slightly higher at the water temperature of 8℃. (3) Since the hatchability of the water-soaked eggs was definitely inferior to that of the control, another experiment was carried out as described below. In experiment Ⅱ another split-split plot experiment was carried out as described for experiment 1. The ages of embryo at water-soaking compared were 13th and 14th days of incubation. The lengths of water-soaking were 2.5 and 5 minutes. The water temperatures compared were 12℃, 16℃, 20℃, and 24℃. The results obtained in experiment II are as follows. (1) The water-soaking before 13th of incubation tended to give better hatchability, although the difference between the ages of water-soaking was statistically insignificant, probably because of the small number of replication. (2) The water-soaking for 2.5 minutes tended to give better hatchability, although the difference was statistically insignificant. (3) The differences between the water temperatures were statistically significant at 5% level. The result of the L.S.D. test showed that the optimum temperature of water-soaking is 24℃. (4) The interaction between the age of embryo and water temperature as well as the 3 way interaction were statistically significant. (5) The results of the t-test showed that hatchability of the lot water soaked on 14th day of incubation for 2.5 minutes at 24℃ is significantly higher than that of the control. As a conclusion, it was evidently proved that the water-soaking on 12th day of incubation for 25 minutes with the water temperature 24℃ improve the hatchability though the results obtained in the two experiments.

부란중 발육계란의 수침처리가 부화율에 미치는 효과 ( 제2보 )

이승규 ( Seung Kyu Rhee ) 한국축산학회 1975 한국축산학회지 Vol.17 No.2

The purpose of this study was to examine the effect of water-soaking hen`s egg during incubation on the hatchability. The following three factors were considered important in the water-soaking:the age of embryo at water-soaking, the duration of water-soaking and the water temperature. Two experiments have been carried out previously to determine the adequate level of each factor that may improve the hatchability. The results obtained in experiments I and II suggest that the water-soaking on 12th day of incubation for 2.5 minutes at 24℃ may improve the hatchability. Since the tested levels of each factor in two experiments had some limitation, it cannot be assured that the most appropriate levels of each factor were compared. This experiment was carried out to determine if there are more appropriate levels of the factors examined and to determine the applicability of the water-soaking treatment by examining the rate of weak chicks, the rate of piping, and hatched embryo on 20th day of incubation. The ages of embryo at water-soaking in the thrd experiment mere 10th and 12th day of incubation. The lengths of water soaking were 0.5 and 2.5 minutes. The water temperatures compared were 24℃ and 32℃. In this study a split-split plot experiment just as in experiment I and II was employed to test the duration of water-soaking at two different water temperatures on 10th and 12th day of incubation. The main plots were the age of embryo at water-soaking. In each main plot, there were sub-plots with the two different durations of water-soaking; 0.5 and 2.5 minutes. Each sub-plot was divided into 3 sub-sub-plot as for water temperatures of 24℃, 28℃ and 32℃. The results obtained in this third experiment are as follows: 1. Hatchability: 1) The differences between the ages of embryos, those between the length of water-soaking, and the interaction between the age and length were statistically insignificant. However, in view of the results obtained in Experiment I and II, the most appropriate age and length of water-soaking appear to be the water-soaking for 0.5 minutes on 12th day of incubation. 2) The difference between the water temperatures was statistically significant at 5% level. The results of the L.S.D. test showed that the water soaking at 24℃ is significantly superior to those at 28℃ or at 32℃. The difference between the water-soakings at 28℃ and 32℃ was statistically insignificant. 3) The interaction between the age of embryo and water temperature as well as the 3-away interactions were statistically insignificant. However, the results of the test showed that the hatchability of the lot water-soaked on 12th day of incubation for 0.5 minutes at 24℃(D₂S₁T₁) is significantly higher than that of the control. 2. Rate of weak chicks: None of the main effects or interact-ions were statistically significant for the rate of weak chicks. The difference between the control and the recommended lot, D₂S₁T₁, in the rate of weak chicks was statistically insignificant. This suggests that the rate of weak chicks was not increased by the water-soaking treatment. 3. Rate of the piping and hatched embryos: None of the main effects or interaction were statistically significant for the rats of piping and hatched embryos on 20th clay of incubation. The D₂S₁T₁ lot had significantly higher rate than the control, suggesting that the hatching was not delayed by the D₂S₁T₁ treatment. On the basis of the results obtained in this experiment, it is concluded that the water-soaking on the 12th day of incubation for 0.5 minutes at 24℃ may improve the hatchability without any harmful effects on the viability or on the rate of piping and hatched embryo, and that the water-soaking could be recommended for practical use.

한국 자동차 부품업체 중국 현지법인의 전략적 역할 유형 구분

김경태(Kyungtae Kim),이승규(Seung-Kyu Rhee),오중산(Joongsan Oh) 한국생산관리학회 2011 한국생산관리학회지 Vol.22 No.1

본 연구의 목적은 군집분석을 통해 국내 자동차 부품업체 중국 현지법인들을 전략적 역할에 따라 여러 가지 유형으로 구분하고, 유형들 간의 역량 차이를 비교 분석하며, 시간이 지남에 따라 전략적 역할이 어떻게 변화하는 지를 규명하는 것이다. 선행연구와 비교하여 본 연구는 다음과 같은 세 가지 주요한 특징을 갖고 있다. 첫째, 본 연구는 완성차 업체를 중심으로 진행된 기존 연구들과 달리 부품업체 관점에서 현지법인의 역할을 분석하였다. 이 과정에서 기존 이론에서 고려하지 못하였던 주고객사와 동반 진출한 업체들의 전략적 역할을 분석틀에 반영하였다. 둘째, 선행연구들과 달리 현지법인 전체가 아닌 현지법인 기능 부문들을 기준으로 역량을 평가하였다. 셋째, 현지법인의 전략적 역할 변화과정을 과거시점부터 현재를 거쳐 미래전망까지 동태적으로 고찰하였다. 또한 전략적 유형별로 기능부문별 역량수준이 초기에 비해 어떻게 변하였는지 검토하였다. 현지법인의 고객별 판매 비중을 독립변수로 고려하여 실시한 군집분석 결과, 현지법인의 전략적 역할은 현지시장 개척 형․수출 주도형․주고객사 대응형과 같은 세 가지 유형으로 구분되었으며, 이러한 유형은 시간이 지나면서 조금씩 변한다는 사실을 확인하였다. 또한 진출초기와 달리, 시간이 지나면서 서로 다른 전략적 유형들 간에 일부 역량의 수준 차이가 발생하고 있음을 확인하였다. 마지막으로 현지법인들은 진출 초기에 비해 시간이 지나면서 역량이 더 높은 수준으로 발전했음을 알 수 있다. The purpose of this study is to identify and characterize the different types of local subsidiaries of Korean automotive part suppliers in China based on their strategic role. This study also examines the changing process of the strategic role and conducts the comparative analysis on the level of the functional capabilities among the classified groups of local subsidiaries. Three important features of this study are as follows. First, the analysis was conducted from the perspectives of part suppliers, not of the car makers. Accordingly, we first needed to provide proper theoretical rationale for the cluster analysis by analyzing and supplementing the outcomes and limitations of existing theories. Especially, we tried to capture the clientfollowing feature of part suppliers based on the close relationship between buyer and supplier in automotive industry. Second, while most extant studies analyzed the capabilities of local subsidiaries at an whole subsidiary-level, this study adopted the functional capabilities as an analytical unit in order to conduct more systematic and accurate evaluation of the capabilities level. Third, in order to examine the evolutionary aspect of the strategic role, we conducted cluster analysis at three different points of time (the early, present, and future). Using variable of the percentage sales to various customers, our study, first, identified three distinct clusters of local subsidiaries: local market-seeking, offshoring, and followed-client responding. We also found that the strategic role of local subsidiaries evolved in the course of the continual interaction with internal and external network actors. Second, we conducted comparative analysis on the level of functional capabilities among three clusters, and between the past and the present. Finally, we tried to explain those results based on the unique characteristics of each cluster.

완성차업체-공급업체간 협력이 성과에 미치는 영향과 기술불확실성의 조절효과 - 한국 자동차 산업을 중심으로

오중산(Joongsan Oh),이승규(Seung-Kyu Rhee) 한국생산관리학회 2008 한국생산관리학회지 Vol.19 No.1

  본 연구의 목적은 완성차업체-공급업체간 협력이 성과에 미치는 영향과 이러한 영향에 대한 기술불확실성의 조절효과를 확인하는 것이다. 다섯 가지 협력 유형 중에서 협력적 의사소통과 신차개발과정에서의 협력 및 전략적 구매는 완성차업체 성과에, 협력적 문제해결과 공급업체 개발은 공급업체 성과에 각각 긍정적인 영향을 미치고 있다. 양자의 성과에 긍정적인 영향을 미치는 협력은 유형적 차이를 보일 뿐만 아니라, 활성화 정도에 있어서도 차이를 보이고 있다. 공급업체들은 전략적 구매가 가장 활발하다고 인식하는 반면, 공급업체 개발은 매우 저조하다고 인식하고 있다. 한편 신차개발과정에서의 협력이 완성차업체 성과에 미치는 영향은 기술불확실성에 의해 억제되고 있음이 확인되었다. 이는 기술불확실성의 조절효과가 존재함을 의미하는데, 기술불확실성이 큰 경우에는 신차개발과정에서의 협력이 활성화되면 오히려 완성차업체 성과가 약화됨을 의미한다. 본 연구의 의의는 협력 유형을 네 가지 기준에 의해 다섯 가지로 구분한 점과 기술불확실성을 조절변수로 고려하였다는 점 및 근래 양적·질적으로 성장하고 있는 한국 자동차 산업을 대상으로 실증연구를 진행하였다는 점이다. 하지만 공급업체를 대상으로 주관적 인식지표를 활용한 점과 협력의 질적 차이를 고려하지 못했다는 점 및 표본이 아주 크지 않다는 점은 본 연구의 한계라고 할 수 있다.   The purpose of this study is to identify causal relationships between car assembler-supplier collaboration and performance and moderating effects of technology uncertainty on such relationships. Of the five types of collaboration, collaborative communication, collaboration in new car development process, and strategic purchasing have positive influences on carmakers’ performance. Whereas collaborative problem solving and supplier development positively affect suppliers’ performance. Suppliers perceive that strategic purchasing is the most vitalized collaboration type. In contrast, supplier development that is the factor affecting suppliers’ performance is considered as the least vitalized type. Of particular note is that the positive effect collaboration in new car development process has on carmakers’ performance is alleviated as technology uncertainty grows. This means that the moderating effect of technology uncertainty on the causal relationship between them exists. This research is one of the few studies which classify collaboration types according to some criteria and consider technology uncertainty as the contingency factor. In addition, this paper targets Korean automotive industry which has grown fast nowadays in terms of quality as well as quantity. However, we use subjective and perceptional measurement variables, which is the limitation in this study. It is also a pity that sample size is not large enough to generalize research results.

동반진출 공급업체의 공급사슬진화에 대한 탐색적 사례연구

오중산(Joongsan Oh),이승규(Seung-Kyu Rhee),김경태(Kyungtae Kim) 한국생산관리학회 2008 韓國生産管理學會誌 Vol.19 No.2

  본 연구의 목적은 완성차업체와 북경에 동반 진출한 공급업체들을 대상으로 공급 사슬상ㆍ하류의 진화내용을 확인하고, 이러한 진화에 영향을 미치는 요인을 규명하며, 전략적 역할 변화를 살펴보는 것이다. 공급업체의 해외진출이 활성화되는 시점에 공급업체 입장에서 동반진출과 해외생산법인의 공급사슬진화를 규명하는 것은 실무, 이론적으로 의미 있는 연구라고 할 수 있다. 본 연구는 사례연구를 통해 다음과 같은 결과를 도출하였다. 첫째, 공급업체들은 초기에 품질안정화를 목적으로 공급사슬 상류를 구성하였고, 이후 원가절감을 위해 부품 및 소재의 현지화 비율을 높이고 있다. 둘째, 공급사슬 하류에서는 대부분의 공급업체들이 여전히 동반 진출한 완성차업체와 전속 거래하지만 일부 업체는 점차 거래기업을 다변화하고 있다. 셋째, 공급사슬상ㆍ하류가 변함에 따라 업체별로 차이는 있지만 생산·구매·영업·연구개발과 같은 관련 부문 기능들이 활성화되고 초기의 동반진출 성격이 희석되어 궁극적으로 공급 업체들의 전략적 역할이 변하고 있다.   The purpose of this study is to verify the evolutionary process in the upstream and downstream supply chain of the suppliers, which have expanded with the automotive manufacturers into Beijing, China and to examine factors affecting the evolutionary process and how the strategic role has changed. Originally, suppliers have induced the second-tier suppliers for quality stabilization and thereafter increased the localization percentage of parts and materials by developing local second-tier suppliers for cost reduction. Upon the process above, three factors have lead to the changes in the upstream supply chain: first, internal capabilities of the suppliers that have accompanied manufacturers; second, support from the headquarters and the manufacturers; third, increasingly competitive environment in Chinese automotive market. Some suppliers have diversified their customer base through their local marketing capabilities built on their own or under the support of the headquarter, thereby was able to prepare against the potential risk from the manufacturer. On the other hand, suppliers lacking in experience of customer diversification, or highly depending their sales on the manufacturing company are in difficulty for customer diversification. Most suppliers have actively innovated on the manufacturing activities, however the degree of innovation effort for the marketing, purchasing or R&D activities varies in their functional diversification and activation in accordance with the suppliers. In addition, sometimes things happened that the original joint overseas expansion characteristic has been diluted over time. Some suppliers have appeared to aim at customer diversification or manufacturing cost reduction in related to entry purpose. As such, the strategic role of the suppliers has slowly changed along with the change of their local function and entry purpose.
