본 연구는 미세전류자극이 비만인의 체성분과 혈중지질성분의 변화에 미치는 효과를 규명하고, 복합운동의 효과와 비교함으로써 효과적인 체형 관리 방안으로서 미세전류자극의 유용성을 밝히고자 하였 다. 체지방율 30% 이상인 여대생 30명을 통제집단, 복합운동집단, 미세전류자극집단으로 분류하였으며, 각 집단 별 4주간의 처치 전후 체중, 체지방율, 허리 둘레 등의 체성분 요인과 TG, TC, apolipoprotein 등의 혈중지질성분을 측정한 자료를 분석하여 다음과 같은 결과를 얻었다. 통제집단에서는 모든 측정 항목에서 통계적으로 유의한 차이가 나타나지 않은 반면 복합운동 집단에서는 허리둘레와 TC가 유의하게 감소한 것 으로 나타났고, 미세전류자극 집단에서는 체중, 체지방율, 허리둘레, apolipoprotein 등이 유의하게 감소한 것으로 나타났다. 이러한 연구결과를 고려할 때 미세전류 자극은 비만인의 체성분과 혈중지질성분을 개선 시켜 건강한 신체를 갖도록 하는데 효과적인 중재 방안으로 제안할 수 있다.

The decommissioning waste generated during the dismantling of a nuclear power plant has various types and radioactivity levels and is characterized by being generated in a large amount in a short time. For the safe and efficient management of decommissioning waste with these characteristics, the Korea Radioactive waste Agency (KORAD) is developing a large container for decommissioning waste. And the Waste Certification Program (WCP) requirement was developed for the development of a Waste certification program for nuclear power plant operators that can prove whether the transfer/ acceptance criteria are satisfied at the step of generation of decommissioning waste packages. The radioactive waste profile, which is a waste quality certification document required by the WCP requirements, allows the KORAD to confirm that the disposition suitability evaluation was performed for each process of decommissioning waste and radiological characteristic data were evaluated appropriately. Therefore in this study, in order to propose a draft of a radioactive waste profile for large packages of decommissioning waste, overseas cases and the draft radioactive waste profile of the WCP requirements was analyzed. In addition, it was attempted to increase the utility of the derived waste profile by clearly suggesting the treatment methods for each waste stream considering the physical and radioactive characteristics evaluation methods of large decommissioning waste packages. The proposed large decommissioning waste profile can be used in the future development of a nuclear power plant operator’s decommissioning waste certification program, as well as KORAD’s a disposal facility safety evaluation and improvement of the waste tracking management system (WTS).

This research was conducted to evaluate quality changes in traditional Doenjang and manufactured Doenjang during a storage period of 8 weeks. Low-salt Doenjang and commercial Doenjang were purchased from different manufacturers and proximate analysis as well as changes in isoflavone, polyphenol, flavonoid contents of the samples were investigated using a mass spectrophotometer. The salinity of traditional Doenjang, low salt Doenjang, and commercial Doenjang were 13.2±1.15, 7.17±2.74, 10.67±0.35%, respectively and the salt concentrations of the soybean pastes did not change during storage. After 8 weeks at 35℃, chromatic values of all the paste samples decreased somewhat, with traditional Doenjang exhibiting fewer changes as compared to manufactured Doenjang. Amino acid nitrogen, acidity, microbial population all tended to increase with time, although some samples showed fluctuations during the test period. Moreover, the total isoflavone contents of traditional Doenjang increased with storage time while that of manufactured Doenjang tended to decrease. The isoflavone aglycone was shown to be the highest in traditional Doenjang, while isoflavone glycoside was abundant in manufactured Doenjang. Total flavonoid contents showed similar trends regardless of samples; initial contents of total flavonoid was 0.6 mg/g which increased to more than twice to 1.4 mg/g at the end of storage period. Composition profile of Doenjang extracts was analyzed using UPLC-Q-ToF

The present study investigated the effects of fermented potato protein (FPP, Lianol® ferity) during gestation and lactation on productivity of sows. A total of 50 crossbred sows (Landrace×Yorkshire) in their 3 to 5 parities were allotted to one of two treatments (n=25) including control and FPP groups. FPP tablets applied in sows in two stages. Stage one involved applying FPP daily from 3 days before farrowing to 2 days after for 5 consecutive days. The second stage also involved a 5 day period around weaning time from 3 days before to 2 days after. After farrowing, the amount of feed offered 3 times per day gradually increased from about 3.6 kg at farrowing to 8.4 kg at late lactation. During the first lactation FPP tended to increase backfat thickness (BFT) at weaning at the first (p=0.069) whereas FPP increased BFT (p<0.05) at weaning in the second lactation. There was no significant effect of FPP on body weight changes and daily feed intake of sows. Decreased weaning to estrus interval was associated with applying lianol tablet at the second lactation (p<0.05). Weight of born alive piglets, weaned piglets and total weight gain were greater in FPP group at the second lactation (p<0.05). Applying FPP tended (p=0.062) to increase insulin like growth factor-Ⅰ(IGF-I) at the weaning time in the first lactation. The effect of FPP on IGF-I was significant at the second lactation, revealing a higher concentration in blood at post farrowing and weaning time (p<0.05). This study shows the benefit of using FPP tablets in sows to increase blood IGF-I and both initial and final litter size to improve piglet weaning weights.

Cotesia plutellae bracovirus (CpBV) is a bracoviral polydnavirus and a parasitic factor of an endoparasitioid wasp, C. plutellae, which parasitizes the diamondback moth (DBM) larvae. CpBV genome was reported to consist of 35 circular segments and encode 157 predicted open reading frames (ORFs). This study revisited and re-annotated the CpBV genome. Total ORFs consist of 15 groups of known gene or gene families as well as hypothetical (HP) group. All 74 HP genes are matched to other PDV genes. RNASeq analysis indicates that 147 genes out of 157 predicted ORFs are expressed in the parasitized DBM at the first day or 7 days after parasitization. At the early parasitic stage, CpBV genes annotated as ELP, BEN, E94K, DUFB, PTP, and HP are highly expressed compared to late parasitic stage. Interestingly, highly expressed genes at the late parasitic stages are HPs.
