  • The purpose of this study was that to estimate the microbial and sensory quality by the method and time of holding in the step of holding of Cow's Knee Broth, Stir-Fry Pork and Cooked Cuttlefish that were provide at the industry foodservice establishment, then to suggest safer feeding by the reasonable holding method. The results are as follows: Cow's Knee Broth: holding at room temperature was shown that the number of mi- crobiology by passage of the holding time was higer than the case of holding at steam table, but it was lower after reheating it. As a result of sensory test, it was exellent to holding at steam table and to reheat after holding room temperature within four hours and six hours each. Stir-Fry Pork: as a result of microbial analysis, in the case of holding at the steam table microbes increased safer two hours, but after four and six hours they little reduced. In the case of holding at room temperature the number of microbes increased according to the passage of time. As a result of sensory analysis, its taste of room temperature holding was fine until four and six hours each. Cooked Cuttlefish: as a microbial analysis, it was shown that the amount of total plate counts of room temperature holding ten times as high as the latter after six hours. As the result of sensory analysis, the cold holding was better until six hours and the room temperature holding was fine just until two hours. As a result of food poisoning bacteria, it was negative in every test in sample against Salmonella, Staphylococcus aureus, Vibrio parahaemolyticus.

  • Purpose - Although it has been 10 years since the university technology holding company was launched, it is currently facing operational limitations. The purpose of this study is to study the growth strategy of university technology holding companies by investigating the status and problems of university technology holding companies. Research design, data, and methodology - In this study, the status of university technology holding companies was analyzed based on the survey data issued by the University Technology Holding Companies Association. Due to the lack of research on university technology holding companies, policy alternatives were suggested by examining problems based on literature research. Result - In this study, an alternative to strengthening the competitiveness of technology holding companies and supporting policies was suggested. As a result of the research, it was discovered as a policy alternative to enhance the independence of technology-owned subsidiaries, develop outstanding talents, and expand the marketing of support programs to create results based on technology holding companies. Conclusion - In previous studies, alternatives to technology commercialization policies have been suggested, but studies on the role and status of detailed technology holding companies are insufficient, and the operation system of technology holding companies and discovery of future growth models are insufficient compared to overseas cases. Therefore, in this study, various policy innovation measures are presented as examples.

  • An oil boom was set up in order to contain diffused oil from spills and for the retrenchment of damage caused by oil Pollution. Therefore, the oil boom anchor needed proper holding power to endure high resistance from flowing streams and to secure the oil boom around the spill, and must dredge directly into the seabed when it is dropped and block oil outflow immediately. This study investigated the holding power of the danforth anchor and the coastal fishing vessel anchor used for oil booms in the KMPRC (Korea Marine Pollution Response Corporation). For each type, a 30 kg and 20 kg anchor were used. The holding power of the danforth anchors were measured by dropping both weights 10 times. However the coastal fishing vessel anchors were dropped only 5 times each, because no substantial differences were found between drops. In the results of the danforth anchors, an anchor awoke occurred in 2 drops of the 30 kg anchor and in 4 drops of the 20 kg anchor, wherein there was no holding power to be measured. With exception to the anchor awoke cases, the maximum holding power of the danforth 30 kg and 20 kg anchors was 250-520 kg and 123-233 kg, respectively. In the case of the coastal fishing vessel anchors of 30 kg and 20 kg, throughout the experiment, there was no occurrence of an anchor awoke. For the 30 kg and 20 kg anchors, the maximum holding power was measured to be 209-230 kg and 155-170 kg, respectively. Therefore, the holding power of the coastal fishing vessel anchor was shown to be much poorer than that of the danforth anchor. However, the holding power of the danforth anchor was very unstable. Due to the occurrences of anchor awoke, there was no holding power and the measurement value of maximum holding power showed too much variation among the drop tests. Also, after the maximum holding power was achieved, anchor awoke occurred easily. In the case of the coastal fishing vessel anchor was much more stabile, because there was no anchor awoke and no instance where holding power failed. Also the maximum holding power was reached quickly and almost no variation occurred among the drop tests.

  • The issue of safety and quality of cooked food served at foodservice institutions has brought more attention to food scientists because the foodservice system is growing and becoming more popular in Korea. In order to control the quality and safety of cooked foods, the production and holding methods of foods should be carefully studied and the implications considered by the foodservice industry. Therefore, studies on microbiological, nutritional, physicochemical and sensory quality are essential in this area. The purpose of the present study was to evaluate the chemical and microbial qualities of salads during holding. Several holding temperatures in the range of 5∼26$^{\circ}C$ were used for holding. Chicken salad and ham & cucumber salad exceeded the standard after 30min of room temperature holding after preparation. Quality deterioration increased at higher holding temperatures, which suggested that refrigerator holding is the most desirable.

  • The optimal reheating conditions to apply the thixoforging and semi-solid die casting process were investigated by changing the reheating time, the holding time, the reheating temperatures, the capacity of the induction heating system, and the adiabatic material size. In the case of solid fraction fs=50% (for semi-solid die casting), the microstructure of SSM (specimen size:$d76{\times}l90$) at the condition of the first elevating time of 4 min, holding time of 1 min and holding temperature of $350^{\circ}C$, the second elevating time of 3 min, holding time of 3 min and holding temperature of $575^{\circ}C$, the third elevating time of 1 min, holding time of 2 min and holding temperature of $584^{\circ}C$, capacity of Q=8.398KW is obtained with globular microstructure and finest. In addition, in the case of solid fraction fs=55% (for thixoforging), the SSM (specimen size:$d76{\times}l90$) at the condition of the first elevating time of 4 min, holding time of 1 min and holding temperature of $350^{\circ}C$, the second elevating time of 3 min, holding time of 3 min and holding temperature of $570^{\circ}C$, the third elevating time of 1 min, holding time of 2 min and holding temperature of $576^{\circ}C$, capacity of Q=12.04KW is obtained with the finest globular microstructure. We saw that the most important factor in a three-step reheating process is the final holding time.

  • This study was performed to predict the multiplication growth patterns of Salmonella typhimurium according to the holding methods and times in cooked foods served at foodservice institutions. When simmered pork in soy sauce and ham and cucumber salad were inoculated with S. typhimurium (7.00 logCFU/g) and tested according to holding methods and times, room temperature holding showed a continuous increase in S. typhimurium count as time passed, whereas 80$^{\circ}C$ heating table sharply reduced the count to 4.00 (logCFU/g) after 2hrs of holding and to zero after 6hrs, which suggested that all S. typhimurium were destroyed. However, 5$^{\circ}C$ refrigerator holding showed a count increase, although it wasis still lower than that at room temperature and at 10$^{\circ}C$ cold table holding, which suggested that S. typhimurium is comparatively resistive to low temperature.

  • 고분자전해질연료전지(PEMFC)의 고분자막의 전기화학적 내구성을 평가하는 펜톤(Fenton)반응과 개회로전위 유지(OCV Holding)방법에 의한 고분자 막의 열화 결과를 비교하였다. 펜톤 반응은 셀 밖에서 OCV Holding 방법보다 더 짧은 시간에 고분자막의 화학적인 내구를 평가할 수 있는 방법이다. 펜톤 반응은 과산화수소 30%, 철이온 80 ppm, $80^{\circ}C$에서 24시간 실시하였다. OCV Holding은 $90^{\circ}C$, 상대습도 30%, OCV에서 168시간 시간 구동하였다. 펜톤 반응에 의해서는 고분자막의 내부에서 열화가 많이 발생하는 현상을 보였다. 반면에 OCV Holding에서는 표면과 내부 전체적인 열화에 의해 막 두께가 얇아졌다. 펜톤 반응에 의해 불소유출속도는 OCV Holding에 비해 10배 이상 높았다. 수소투과속도는 펜톤 반응 24시간에 약 30% 증가하였다. OCV Holding에서는 24시간에 수소투과도가 감소하였고 이후 증가하는 경향을 보였다. 전체적으로 펜톤 반응과 OCV Holding에 의한 고분자막 열화는 차이가 있었다.

  • 한국에 기술지주회사가 도입된 시기는 2008년이며, 2014년 기준으로 대학의 기술지주회사는 39개가 설립되어 운영 중이고 연구소 기술지주회사로는 에트리홀딩스(주)가 유일하다. 기술지주회사는 대학이나 연구소의 기술을 이전하고 창업을 지원하기 위해 설립되었는데, 기술지주회사가 도입된 지 7년이 경과하고 있지만 아직 본격적인 수익을 거두고 있지 않은 실정이다. 지주회사는 기본적으로 투자 회사이고 투자한 기업을 통하여 수익을 거두는 기업이며, 창업투자회사도 창업기업에 투자하여 수익을 거두는 기업으로 기본적으로 지주회사 수익 모델과 유사하다. 본 연구는 국내 2개 창업투자회사에 대한 사례 연구를 통해 기술지주회사의 수익 모델에 대한 바람직한 방향을 제시하고자 하였다. 즉, 재무제표 중심의 정량적 분석 결과, 기술지주회사의 바람직한 사업 모델로는 순수지주회사 보다는 사업도 같이 병행하는 사업지주회사 성격이 보다 적절하다는 것을 제시하였으며, 구체적 사업모델로 인큐베이팅이나 경영자문 등을 추가할 것을 제안하였다.

  • Objective: The aim of this study is to characterize the impact of additional electrical stimulation (AES) and various pre-rigor holding temperatures (for 3 h) on the ageing-potential of hot boned bovine M. longissimus lumborum (LL). Methods: Paired LL loins from 12 bulls were hot-boned within 40 min of slaughter, immediate AES applied and subjected to various holding temperatures (5℃, 15℃, 25℃, and 35℃) for 3 h. Results: AES did not accelerate the rate of rigor attainment, but the 3 h pre-rigor holding temperature did. Shear force values decreased as the pre-rigor holding temperatures increased. AES and holding for 3 h (at 25℃) resulted in higher water-holding capacity. Conclusion: Data confirmed that AES did not influence the various meat quality parameters in the present study, but pre-rigor holding temperature (25℃) alone or in combination with AES resulted in superior meat quality.
