Ten barrows, weaned at 28 days (7.2$\pm$0.1 kg BW), were used to evaluate the effects of feeding extruded full-fat soybeans on intestinal morphology and mucosal cell turnover time. All pigs were fed corn-based diets with half of the pigs receiving diets supplemented with 15.5% soybean meal and 3% soybean oil and the remaining pigs fed a diet in which the soybean meal and oil were replaced by 18.5% extruded full-fat soybeans. The pigs were individually placed in $80{\times}150cm$ metabolic cages and fed twice daily an amount approximately equal to their ad libitum intake for a period of 14 days. On day 14, pigs were weighed and then injected intraperitoneally with $^3$H]thymidine ($100{\mu}Ci/kg$ of BW, specific activity 20 Ci/mmol) 6 h after the morning meal. A pig from each treatment was killed 1, 4, 8, 16, or 24 h postinjection and intestinal tissues were collected. Daily gains for pigs fed the soybean diet and extruded full-fat soybean diet were 0.24 and 0.31 kg/day (p=0.05) with feed conversions of 1.58 and 1.39 (p=0.05), respectively. In comparison with pigs fed soybean meal, pigs fed moist extruded full-fat soybeans had a decreased crypt depth in their duodenum and cecum (p<0.1), while the villus height in the mid jejunum and ileum and the total height (villus height plus crypt depth) of the ileum and mid jejunum increased (p<0.05). The villus width in the duodenum and mid jejunum decreased (p<0.05). The number of crypt epithelial cells in the upper jejunum increased but decreased in the ileum, colon and cecum (p<0.05). The number of villus epithelial cells in the ileum and the upper and mid jejunum increased (p<0.05). The time for migration of epithelial cells in the crypt-villus column decreased (p<0.05) in all sites except the upper jejunum, ileum and cecum. The mucosal turnover rate for all intestinal sites except the upper jejunum, colon and cecum decreased (p<0.05). From these data, we conclude that inclusion of moist extruded full-fat soybeans in weanling pig diets can improve the intestinal morphology and slow the migration rate and turnover time of epithelial cells of the small intestine, especially in the mid jejunum compared with soybean meal.

The double tracer study on erythrokinetics was carried out experimentally with radioactive iron ($^{59}Fe$) and chromium ($^{51}Cr$) in rabbits. The 0.1% canthalidin solution and 1% pot. perchlomate solution was given subcutaneously to 20 rabbits respectively. 3 and 6 days after injection, the blood chemistry, urine examination, ferrokinetics and apparent half survival time of RBC were ($^{51}Cr\;T\frac{1}{2}$)determined. Following were the results: 1) Red blood cell hematocrit and hemoglobin values were moderately reduced and B.U.N. and serum creatinine values were slight]y inercased in the canthalidin group, while B.U.N. and serum creatinine values were within normal limits in the pot. perchlomate group. Reticulocyte values were slight]y increased in the canthalidin group, while was normal range in the pot. perchlomate group. 2) Blood chemistry finding was not significant statistically in both experimental groups, but serum iron value was moderately reduced in both group. 3) Plasma volume was unchanged in both group, but red cell volume and whole blood volume were slightly reduced in both groups. 4) Results of ferrokinetics were as follows: i) The plasma iron disappearance rate was delayed in both groups. Plasma iron turnover rate, red cell iron utilization and red cell iron turnover rate were decreased in both groups, and then red cell iron turnover rate was more decreased than plasma iron turnover rate in both groups. Circulating red cell iron was slight]y increased in canthalidin group and red cell iron concentration was within normal range in both groups. ii) P.I.T.R.-R.C.I.T. value was moderately increased in the canthalidin group and slightly increased in the pot. perchlomate group. Reticulocyte index, red cell iron turnover index, plasma iron turnover index and effective erythropoiesis index were whole]y reduced in both groups. iii) The red cell life span was slightly shortened in the canthalidin group while was within normal range in pot. perchlomate group. The pathologic finding of renal biopsy of the canthalidin group shows a selective damage in glomerulus, while shows almost normal range or slight damage in tubules. And that of the pot. perchlomate group shows a selective damage in tubules with slight damage of glomerulus.

유리천장은 여성들이나 소수민들이 조직 내에서 보다 상위직급으로 승진하는 것을 막는 투명한 장벽이다. 유리천장의 추세는 최근 '우먼파워'와 '양성평등'의 여성정책 등으로 많이 감소되었으나 아직도 많은 기업에서 만연하고 있는 것도 사실이며, 많은 연구에서 뿌리 깊은 유리천장의 존재가 확인되고 있다. 이에 본 연구는 202명의 여행사에 재직 중인 여성종사원을 대상으로 유리천장에 대한 지각, 조직몰입 및 이직의도 간의 관계를 살펴보았다. 분석결과, 유리천장에 대한 지각은 정서적 몰입에 부(-)의 영향을 미치며, 정서적 몰입은 이직의도에 부(-)의 영향을 주는 것으로 나타났다. 따라서 조직몰입을 다차원으로 구분해서 접근할 필요성이 제기되었다. 또한 여행사에 종사하고 있는 여성종사원들은 비록 유리천장을 지각하더라도 이직의도가 없을 수 있지만, 정서적 몰입을 낮게 지각한다면 이직의도가 높아질 수 있다는 것이다. 따라서 여행사 내에서 개인이 감정적으로 애착을 가지고 조직과 혼연일체감을 느끼게 할 경우, 즉 정서적 몰입을 높일 경우 유리천장이 존재하더라도 이직의도를 줄여갈 수 있다는 것을 시사한다.

오늘날 병원의 경영자들은 직원들의 직무만족도와 이직의도에 대해서 많은 관심을 기울이고 있다. 직원들이 병원을 떠나게 되면 그 동안 축적되었던 업무지식과 기술이 다른 곳으로 유출되고, 그에 따라 남은 직원들의 사기가 저하되는 부작용이 나타나고 있다. 이러한 부작용은 병원의 경쟁력의 저하로 이어져, 병원경영이 크게 위협받게 되는 것이다. 본 연구에서는 직원의 직무만족과 이직의도에 영향을 미치는 많은 요인 가운데 특히 경영자의 리더십유형에 초점을 맞추고 있다. 그리고 직무만족과 이직의도 사이의 관계에 있어서 환자와 직원이 갖는 병원의 브랜드이미지의 역할에 대해서도 실증적으로 조사하였다. 연구결과를 통해서 병원의 경영자의 리더십스타일에 따라 직원의 업무만족도에 차이가 있으며, 동시에 직원의 이직의도에도 영향을 미치고 있음을 알 수 있었다. 본 연구의 결과는 병원에서의 바람직한 인적자원관리의 정책을 수립하는데 있어서 방향을 제시해줄 수 있을 것으로 판단된다.

For the implementation of innovative products or services companies use different innovation strategies, in particular, outsourcing is quite widespread, given the high level of specialization and professionalism of companies that provide such services. The aim of this article was to evaluate the link between outsourcing of innovative activities and indicators of companies' efficiency. The methodology of the research includes the methods of correlation analysis and regression analysis to reveal the correlation between the use of outsourcing of innovative products and services and the turnover of the EU enterprises. The results show a high level of innovative activity of EU enterprises (50.3% innovatively active). Innovative business processes are the most widespread form of innovation activity (41% of enterprises implement business processes, and the indicator is higher than 41% in the most developed EU countries). The turnover of enterprises with new or substantially improved products was found to grow by 10.92% for the period 2016-2018. The correlation analysis shows weak direct links between the indicator of turnover growth and the number of enterprises that have independently implemented innovations, or have implemented innovations jointly with third-party companies, or using outsourcing services. The highest level of direct connection was found between the growth of turnover of enterprises that launched a new product for the market and the growth of the number of enterprises that implemented innovations with the involvement of organizations (correlation 0.273). Based on the regression analysis it was found that with a 1% change in the growth rate of the number of innovation-active enterprises, the growth rate of turnover from new or improved products increased by 5.67%. At the same time, with a 1% change in the growth rate of the number of enterprises that implement innovation through outsourcing, the growth rate of turnover from new or improved products will increase by 7.15%.

This study is to understand the relationship between turnover and various conditions. Turnover refers to workers moving from one company to another, which exists in various ways and forms. Currently, a large number of workers are considering many turnover rates to satisfy their income levels, distance between work and residence, and age. In addition, they consider changing jobs a lot depending on the type of work, the decision-making ability of workers, and the level of education. The company needs to accept the conditions required by workers so that competent workers can work for a long time and predict what measures should be taken to convert them into long-term workers. The study was conducted because it was necessary to predict what conditions workers must meet in order to become long-term workers by comparing various conditions and turnover using regression and decision trees. It used Microsoft Azure machines to produce results, and it found that among the various conditions, it looked for different items for long-term work. Various methods were attempted in conducting the research, and among them, suitable algorithms adopted algorithms that classify various kinds of algorithms and derive results, and among them, two decision tree algorithms were used to derive results.
