Cadmium is considered one of the most toxic, non biodegradable heavy metal for the human and animals. The purpose of the present study was to investigate the changes in biochemical parameters of blood and accumulation of cadmium in various tissue caused by various levels of dietary cadmium chloride ($CdCl_2$) in broiler chicks. $CdCl_2$ was administered through drinking water to broiler chicks. In spectral analysis, $CdCl_2$ treatment caused a significant increase in Glutamate pyruvate transaminase (GPT), creatinine and uric acid levels in all treated groups. Intriguingly, the GPT, creatinine, and uric acid levels were significantly higher at 75 mg/kg as compared to the groups treated with high doses (100, 125 and 150 mg/kg) of $CdCl_2$. Atomic Absorption Spectrophotometer (AAS) was used for the determination of Cd accumulation in kidney, liver and Breast muscles. AAS analysis revealed that Cd accumulation is increased in breast muscles as compared to liver and kidney at higher doses of Cd than 75 mg/kg.

The effects of Ganoderma Lucidum consumption (GL) on the liver function and lipid metabolic disorder induced by alcohol consuming were studied in rats using GL powder(1%, 2%, 4%) and 10% ethly alcohol. Thirty-five rats(Sprague-Dawley, male) were divided into five groups and fed experimental diets for seven weeks. The concentrations of serum cholesterol, HDL-cholesterol and triglyceride were the highest in the alcohol group, while the levels were apparently reduced by in groups fed GL. The atherogenic indices(AI) also tended to be higher in the alcohol group. Glutamic oxaloacetic transaminase(GOT) activities were significantly lower in body alcohol + 2% GL and alcohol + 4% GL groups, and glutamic pyruvic transaminase(GPT)activities lower only in the alcohol + 2% GL compared with the alcohol group. Alkaline phosphatase(ALP) activities were not significantly different among the groups. The elevated levels of liver cholesterol and triglyceride due to alcohol consumption, were apparently reduced by GL supplementation. On microscopic observation of liver tissues, fat droplets appeared extensively on the liver-lobule in the alcohol group, while fat droplets appeared only on the central vein in the alcohol + 1% GL group. However, in groups administered 2% and 4% GL, fat droplets appeared similar to the alcohol group. The concentrations of fecal bile acid were significantly increased in groups fed GL. These results indicate that GL exerted some beneficial effects on lipid metabolic disorder caused by long-term alcohol consumption. Thus, it seems that GL may be effective in preventing or curing some aspects of alcohol toxicity. More detailed studies are needed in order to determine proper dietary levels of GL for combating alcohol toxicity.

One of the objectives and aspirations of scientists and engineers ever since the development of computers has been to interact naturally with machines. Hence features of artificial intelligence (AI) like natural language processing and natural language generation were developed. The field of AI that is thought to be expanding the fastest is interactive conversational systems. Numerous businesses have created various Virtual Personal Assistants (VPAs) using these technologies, including Apple's Siri, Amazon's Alexa, and Google Assistant, among others. Even though many chatbots have been introduced through the years to diagnose or treat psychological disorders, we are yet to have a user-friendly chatbot available. A smart generative cognitive behavioral therapy with spoken dialogue systems support was then developed using a model Persona Perception (P2) bot with Generative Pre-trained Transformer-2 (GPT-2). The model was then implemented using modern technologies in VPAs like voice recognition, Natural Language Understanding (NLU), and text-to-speech. This system is a magnificent device to help with voice-based systems because it can have therapeutic discussions with the users utilizing text and vocal interactive user experience.

본 실험은 콜레스테롤식이와 운동수행이란 두 조건을 심순환기 질환의 관련지표로서 혈장 및 간의 지질, 적혈구막의 Na efflux 그리고 혈소판 응집성에 어떠한 영향을 미치는지 조사하였다. 운동에 의해서 체중이 다소 감소하였지만 그렇게 크지는 않았다. 라드를 주 지방원으로 사용한 식이에 0.5% 콜레스테롤첨가는 혈중 콜레스테롤을 2배 이상, 간 콜레스테롤을 8배 이상 증가시켰고 HDL-콜레스테롤을 절반 이하로 떨어뜨렸는데, 특히 운동효과로 예상했던 HDL-콜레스테롤증가는 대조군식이나 콜레스테롤식이에서 나타나지 않았다. 혈중 중성지방은 콜레스테롤 식이군에서 오히려 감소하였고 간의 경우 지방 축척으로 인해 간의 크 기뿐만 아니라 간의 중성지방은 현저히 증가되었다. 체액량 조절 및 혈압과 관계에서 조사된 적혈구의 Na efflux는 Na-K ATPase가 콜레스테롤 식이에 의해 그 활성을 감소되었고 운동이 이를 다소 회복시키는 경향을 보였다. 혈압과의 상관성이 높다고 알려진 Na passive leak은 콜레스테롤과 운동이 각각 독립적으로 증가시키는 요인으로 작용하여 콜레스테롤-운동군이 대조군식이-비운동군에 비해 현저히 증가된 것으로 나타났다. 총 Na efflux는 실험군 간에 큰 차이가 없었고 intracellular Na와의 상관성도 보이질 않았다. 혈소판응집성에 있어서 콜레스테롤식이가 혈소판 응집을 증가시키고 특히 운동이 초기응집을 증가시키는 경향을 보였다. 혈장 GOT 및 GPT수치는 콜레스테롤식이로 인해 현저히 증가됨으로서 간의 병리적 상태를 잘 반영하였고 운동에 의해 감소됨으로서 운동수행이 술이나 고지방식으로 인한 지방간을 호전시켜 줄 수 있으리라 기대할 수 있다. 고지혈증이나 고혈압 환자에 있어서 비약물적 요법으로 식이나 운동을 통한 치료나 예방의 가능성을 규명하기 위한 실험의 결과로서 특히 운동에 대해 일관되고 가시적인 효과가 미흡한 것은 6주간의 짧은 실험기간을 생각할 수 있는데 혈청 지질, Na flux 및 체액, 혈소판 응집성 등 심순환기 질환의 예방에 도움이 되는 운동의 형태나 강도 혹은 지속 기간에 대한 더 많은 연구가 필요하리라 생각된다.

This study aimed to find out the effect of freeze-drying leek against cadmium poisoning on the cholesterol and enzyme activities in serum and superoxide radical, SOD and catalase in liver and kidney of the male rats during the administrered period. In this experiment, male rats of Sprague-Dawley strain were used. The rats were divided into 3 groups which were fed differently either for 5 weeks or for 10 weeks:basal diet, basal diet and cadmium in water and 3 % leek added diet and cadmium in water. Cadmium was administered ad libiturn 100 ppm CdCl$_{2}$ in water. The followings are the results of this experiment. 1. Leek reduced the cholesterol and the activities of GPT increase resulted from cadmium treatment. 2. Leek reduced the rate of cadmium in liver and kidney. 3. Leek reduced the activities of SOR and catalase in liver and kidney, while it enhanced the activities of SOD. 4. Leek reduced the necrosis and swelling in liver and kidney casused by cadmium treatment. This experiment showed that leek-addition group had protective effect against cadmium poisoning and increased ALPase activities in serum. Leek alleviated GPT activities in serum and cadmium concentration, necrosis, and swelling in liver and kidney. Therefore, this experiment concluded that leek has defensive power against cadmium poisoning.

The present study was conducted to investigate the effects of dietary Eucommia ulmoides Oliver leaves(EUOL) on the growth performance and meat quality of broiler chicks. The dietary treatments consisted of the control diet(corn-soybean meal basal), and EUOL 2, 4, and 6% diets. The latter three diets were prepared by adding 2, 4, and 6% EUOL to the control diet. Ninety-six Arbor Acre male broiler chicks were randomly allotted to 16 pens; four pens per treatment and 6 birds per pen. The growth performance and carcass weight of broiler chicks fed EUOL diets were not significantly different(P>O.05) from the control birds. Also, the muscle color degrees(L*a*b *)in brolier chicks were similar to each other. The blood concentrations of protein, sugar and glutamic-pyruvic transarninase(GPT) were not different(P>O.05) between control and treatment groups. The blood total cholestrol content was significantly(P<0.05) decreased by the addition of EUOL. However, the addition of EUOL did not change the muscle components significantly. The bone hardness of broiler chicks fed EUOL was significantly(P<0.05) higher than that of control chicks.

Effects of aluminum (Al) on plasma vitellogenin (VTG), alkaline-labile phosphorus (ALPP), calcium (Ca), glutamate pyruvate transaminase (GPT), the hepatosomatic index (HSI), and hepatic Al concentration were examined in estradiol-$17{\beta}$ ($E_2$)-administered immature rockfish Sebastes schlegeli. Fish were injected intraperitoneally with $E_2$ (5 mg/kg body weight [BW]) and/or Al (0, 0.1, 1, 5, and 10 mg/kg BW) and plasma and liver samples were extracted 7 days later. After sodium dodecyl sulfate polyacrylamide gel electrophoresis, the relative amount of VTG was determined by integrated optical density. VTG accounted for 23.6% of the total proteins in the control group, but this value decreased with increasing Al administration. Al reduced the concentrations of ALPP and Ca in a concentration-dependent manner and significant reduction occurred at Al concentrations greater than 5 mg/kg. The concentration of GPT increased in a concentration-dependent manner in all Al-administered rockfish. The concentrations of Al in the liver also increased, and HSI was decreased, in a concentration-dependent manner. These results suggest that Al inhibits $E_2$-induced VTG production by being toxic to hepatocytes in marine fish.

Mobile applications can be easily downloaded and installed via markets. However, malware and malicious applications containing unwanted advertisements exist in these application markets. Therefore, smartphone users install applications with reference to the application review to avoid such malicious applications. An application review typically comprises contents for evaluation; however, a false review with a specific purpose can be included. Such false reviews are known as fake reviews, and they can be generated using artificial intelligence (AI)-based text-generating models. Recently, AI-based text-generating models have been developed rapidly and demonstrate high-quality generated texts. Herein, we analyze the features of fake reviews generated from Generative Pre-Training-2 (GPT-2), an AI-based text-generating model and create a model to detect those fake reviews. First, we collect a real human-written application review from Kaggle. Subsequently, we identify features of the fake review using natural language processing and statistical analysis. Next, we generate fake review detection models using five types of machine-learning models trained using identified features. In terms of the performances of the fake review detection models, we achieved average F1-scores of 0.738, 0.723, and 0.730 for the fake review, real review, and overall classifications, respectively.
