This study was conducted to evaluate the dietary supplementation of two Bacillus spp. on digestibility, growth performance, innate immunity, and water ammonia level of Litopenaeus vannamei. A control diet was made without the probiotic supplementation, and four other diets were prepared by including B. subtilis (BS) alone (0.1 × 1010 and 0.2 × 1010) or a mixture of BS and B. pumilus (BP) (0.1 × 1010 and 0.2 × 1010). Quadruplicate groups of shrimp (0.14 g) were hand-fed one of the diets for 8 weeks. Shrimp fed diets containing Bacillus spp. showed significantly higher apparent digestibility coefficient of protein and dry matter than shrimp fed the control diet. The growth performance was significantly improved in shrimp fed higher dose (0.2 × 1010) of the Bacillus spp. compared to the control group. Innate immunity of shrimp fed the probiotic diets was significantly enhanced compared to the control group. In a water ammonia test, culture water of the probiotic diets had lower total ammonia concentration than that of the control diet. The results in this study suggest that Bacillus spp. can positively affect digestibility, growth performance, feed efficiency, innate immunity, and water quality for L. vannamei.

Since Supreme Leader Kim Jong-un took power, North Korea has recognized the importance of the wetland ecosystem, which is a major component of the natural ecosystem, and has been attempting to systematically manage, preserve, and use wetlands. North Korea's interest stands out in establishing foundation for the wetland management system, a cooperative system for wetland conservation and sustainable use, a wetland conservation system, and promoting wetlands. The change in North Korea's perception of wetland space is largely due to the re-recognition of ecosystem services provided by wetlands. In addition, changes of circumstance faced by North Korea, such as fostering tourism industry and need to participate in the implementation of sustainable development, served as a strong driving force behind the re-recognition of ecosystem services provided by wetlands. The North Korean authorities' interest in the preservation and use of wetlands is a welcome issue for the establishment of a community of life on the Korean Peninsula; and for the establishment of community of human. This is because the nature of wetlands inevitably requires cooperation and solidarity from the international community. It is necessary to elicit North Korea's demand for cooperation reflected in the change of wetland space perception and to gradually promote inter-Korean wetland cooperation based on the results.

본 논문에서는 IoT 기술을 이용하여 전기, 수도, 가스의 양을 실시간으로 모니터링하고, 누적 사용량도 확인할 수 있는 시스템을 설계하였다. 상시 모니터링을 통해 누진세 예방 및 사용량을 조절하여 에너지를 절약하고, 환경을 보존할 수 있을 것이다. In this paper, IOT technology was used to monitor the amount of electricity, water, and gas in real time and design a system that can check cumulative usage. Through continuous monitoring, it will be possible to save energy and to preserve the environment by controlling the progressive tax and controlling the usage amount.

Three isolates belonging to the ascomycetous genus Zygotorulaspora were obtained from the fruits of Cornus officinalis and Smilax china, and flowers of Dendranthema zawadskii var. latilobum in Gongju-si, Korea. Phylogenetic Analyses of the LSU D1/D2 domain and ITS region sequences supported the recognition of two new species: Zygotorulaspora cornina sp. nov. (type strain NIBRFGC000500475 ¼ KACC93346P<sup>PP</sup>) and Zygotorulaspora smilacis sp. nov. (type strain NIBRFGC000500476 ¼ KACC93347P<sup>PP</sup>). The two novel species revealed no growth on D-Galactose, unlike the other six species in the genus Zygotorulaspora. They are distinguished from each other by their phylogenetic differences and phenotypic characteristics such as assimilation of xylitol, 5-keto-D-gluconate, and ethanol. All species in the genus Zygotorulaspora including the two novel species have phenotypic traits of genus Zygotorulaspora: asci are persistent, sucrose and raffinose are assimilated, and m-inositol is not required for growth, and they are mainly associated with plants.
Heterotopic pregnancy; Ectopic pregnancy with multiple intrauterine pregnancy; Two case reports

Heterotopic pregnancy is the simultaneous presence of intrauterine and ectopic pregnancy. Although it is a very rare disease, the incidence of ectopic pregnancy is increasing as use of artificial reproductive technology increases. CASE 1; A 38-year-old twin pregnant nullipara woman with 6+2 weeks of gestation visited emergency room with abdominal pain and vaginal bleeding. Her current pregnancy was through in vitro fertilization-embryo transfer. On vaginal ultrasound, two intrauterine gestational sacs and left adnexal complex lesion were confirmed, and a large amount of fluid was confirmed in peritoneal cavity. She was diagnosed with heterotopic pregnancy and underwent emergency laparoscopic left salpingectomy. Of the twins with intrauterine pregnancy, one fetus missed abortion at 10+0 weeks of gestation, and the other was born full-term by cesarean section at 38+4 weeks of gestation. CASE 2; A 32-year-old primipara woman underwent intrauterine insemination after superovulation induction. she was visited to emergency room with abdominal pain and vaginal bleeding at 5+5 weeks of gestation. On vaginal ultrasound, four intrauterine gestational sacs (fetal pole and fetal heartbeat were confirmed in three sacs, but fetal poles were not seen in the other sac) and left adnexal complex lesion were confirmed, and a large amount of fluid was confirmed in peritoneal cavity. She was diagnosed with heterotopic pregnancy and underwent emergency laparoscopic left salpingectomy. Triple pregnancy, which was intrauterine pregnancy, was maintained as twin pregnancy by performing selective fetal reduction at 6+3 weeks of gestation. Twin fetuses were born full-term by cesarean section at 37+3 weeks of gestation. Even if intrauterine pregnancy is confirmed, the possibility of ectopic pregnancy cannot be excluded. Therefore, we recommend careful confirmation of adnexa through vaginal ultrasound even if intrauterine pregnancy is confirmed.
Taurine supplementation in diet for olive flounder at low water temperature

The objective of this study was to examine the effect of dietary supplementation of taurine for juvenile olive flounder (Paralichthys olivaceus) at low water temperature ($16.4{\pm}0.36^{\circ}C$). Fish meal (FM)-based diet was used as the control diet. Four other experimental diets were prepared by adding taurine to FM-based diet at 0.25, 0.50, 1.00, and 1. 50% (T1, T2, T3, and T4, respectively). Each experimental diet was fed to triplicate groups of fish (initial mean body weight, 19.5 g) for 10 weeks. At the end of the feeding trial, growth performance and feed utilization, hematological parameters, non-specific immune responses, whole-body proximate composition, and liver mRNA expression of insulin-like growth factor-1 (IGF-1) were investigated. Feed conversion ratio was significantly reduced while protein efficiency ratio was significantly increased in taurine-supplemented groups. Hematocrit and hemoglobin were also significantly increased while plasma cholesterol levels were decreased in taurine-supplemented groups than those in the control group. Nitroblue-tetrazolium, myeloperoxidase and lysozyme activities, and plasma immunoglobulin level were significantly increased by taurine supplementation. These results suggest that dietary taurine supplementation is effective in improving growth performances, feed utilization, and innate immunity of olive flounder in low water temperature season.
