  • This study used questionnaires to investigate how pre-service elementary teachers understand ocean acidification. As a result of gender, female teachers were more aware of ocean acidification than male teachers, but male teachers had a higher average rate of correct answers, with a lower standard deviation. Teachers from the natural sciences knew more about ocean acidification than did teachers the liberal arts. Teachers ranked environmental crisis in order of most dangerous to least dangerous as follow: global warming and the greenhouse effect, ozone depletion, ocean acidification, and acid rain. About 46.7% of teachers learn about ocean acidification through education, followed by broadcasts, school lectures and the internet. The educational materials most desired for teachers were videos related to ocean acidification. Pre-service elementary teachers have two broad perspectives on ocean acidification. Firstly, they refer to economic loss and food shortages, and secondly, they note that there is a need for improved awareness and publicity about ocean acidification. The role of elementary school teachers is important because their awareness of environmental issues has a considerable effect on teachers perception of the environment. Revitalizing education on ocean acidification and government support are necessary to effectively communicate the seriousness of ocean acidification. Lastly, we need to study ocean acidification in detail so as to be able to persevere toward protecting our ocean ecosystem.

  • At a turn of the third millennium the world storms and quickly changes. It became difficult to expect what expects us tomorrow. The most important are questions of recovery from the crisis and rescue of mankind from forthcoming global changes: warming of climate, water and food problems, social, economic and political conflicts that are shaking the world and other various cataclysms, accidents, negative processes. It puts before mankind the problem which never solved by our civilization. All this is caused by ignoring of objective economic laws, laws of wildlife and also by violation of cyclic development management's laws. In article the concept of strategy of mankind's survival in XXI and next centuries, the principles of creation of planetary house of universal civilization for post-industrial world based on spirituality scientific and technological revolutions, ecology, space exploration, economy and world safety are considered. Introduction of uniform universal measurement of currency for the whole world in the form of "power" is offered. Important aspect of a research is theoretical postulate on integrated innovative society. The author puts forward a new paradigm of government on a basis of 5 spirals. The basic model of forced development of small and medium business, including 9 projects, is developed.

  • We report a novel HPLC method for analyzing the capsaicinoids and nonivamide. The following conditions were used: a total column and column temperature of $3^{\circ}C$, a detection wavelength of 280 nm, an eluent containing acetonitrile : 0.5% formic acid(31:69, v/v). The experimental data was compared with standard nonivamide and capsaicin. The results showed that nonivamide was eluted in 96.7 minutes with a recovery ratio of 96.5% after adding known nonivamide. In addition, the detection limit for nonivamide was 18.6 ng. The capsaicinoids from Korean pepper were extracted (after blooming 60th) from 3 breeds cultivated in Korea, Buchon, Chungyang and Hanbando. and crisis it analyzed sympathizes the nonivamide in the result nonivamide from the Buchon and the Chungyang which are not detected from the Hanbando $0.16{\sim}0.24{\mu}g/g$ it detects with very small amount it contains it confirmed the each capsaicinoid with the HPLC and the LC-MS. These results are expected contribute to the quality control of various product processes, which includes product delivery inspection as well as examining the capsaicinoids present in the product for possible medicine manufacture and various foodstuff, and the nonivamide content, which may be a feed for various manufacturing processes involving chemical synthesis.

  • To investigate the diversity of gastrointestinal microflora and lignocellulose-degrading enzymes in wild Asian elephants, three of these animals living in the same group were selected for study from the Wild Elephant Valley in the Xishuangbanna Nature Reserve of Yunnan Province, China. Fresh fecal samples from the three wild Asian elephants were analyzed by metagenomic sequencing to study the diversity of their gastrointestinal microbes and cellulolytic enzymes. There were a high abundance of Firmicutes and a higher abundance of hemicellulose-degrading hydrolases than cellulose-degrading hydrolases in the wild Asian elephants. Furthermore, there were a high abundance and a rich diversity of carbohydrate active enzymes (CAZymes) obtained from the gene set annotation of the three samples, with the majority of them showing low identity with the CAZy database entry. About half of the CAZymes had no species source at the phylum or genus level. These indicated that the wild Asian elephants might possess greater ability to digest hemicellulose than cellulose to provide energy, and moreover, the gastrointestinal tracts of these pachyderms might be a potential source of novel efficient lignocellulose-degrading enzymes. Therefore, the exploitation and utilization of these enzyme resources could help us to alleviate the current energy crisis and ensure food security.

  • 동남아의 1천년에 관한 우리의 얘기는 아직도 쌀의 8천년에 관한 아시아의 얘기를 시작조차 못하고 있다. 그러한 서사가 왜 우리의 역사책에는 실리지 않는가? 적어도 동남아에 있어서 역사는 여전히 민족주의를 맴돌고 있다. 따라서 모든 민족은 농민과 전답이 아니라 제왕과 전투가 역사의 주연으로 등장하는 각자의 얘기를 가지고 있다. 그 줄거리는 정치와 민족성이지 농업과 생태학이 아니며, 그 가르침은 갈등과 경쟁이지 협동과 상생이 아니다. 그렇다면 지금도 숨어있는 것은 쌀이 일찍이 만들었고 아직도 좋아하는 지방의 협동과 지역의 보편성이다(O'Connor 2004, 29).

  • Long-chain fatty acid oxidation disorders (LC-FAOD) are an autosomal recessive inherited rare disease group that result in an acute metabolic crisis and chronic energy deficiency owing to the deficiency in an enzyme that converts long-chain fatty acids into energy. LC-FAOD includes carnitine palmitoyltransferase type 1 (CPT1), carnitine-acylcarnitine translocase (CACT), carnitine palmitoyltransferase type 2 (CPT2), very long-chain acyl-CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), and trifunctional protein (TFP) deficiencies. Common symptoms of LC-FAOD are hypoketotic hypoglycemia, cardiomyopathy, and myopathy. Depending on symptom onset, the disease can be divided as neonatal period, late infancy and early childhood, adolescence, or adult onset, but symptoms can appear at any time. The neonatal screening test (NBS) can be used to identify the characteristic plasma acylcarnitine profiles for each disease and confirmed by deficient enzyme analysis or molecular testing. Before introduction of NBS, the mortality rate of LC-FAOD was very high. With NBS implementation as routine neonatal care, the mortality rate was dramatically decreased, but severe symptoms such as rhabdomyolysis recur frequently and affect the quality of life. Triheptanoin (Dojolvi®), the first drug for pediatric and adult patients with molecularly confirmed LC-FAOD, has recently been approved by the US Food and Drug Administration in 2020. In this review, the diagnosis of LC-FAOD and treatment including triheptanoin are summarized.

  • Recent trends in agricultural globalization have brought on a crisis to our already impoverished Korean farmers. This study was proposed to assist in comparing the health and dietary characteristics of farmer families that have chronic disease patients to farmer families that do not have chronic disease patients. For the study, 1870 families were selected from 9 rural Korean provinces. Trained evaluators interviewed farmer housewives to collect demographic, health behavior, and dietary relative information about family members. Statistical analyses were performed using SAS (ver 8.2). Chi-square tests and General Linear Models were also used. In general, patient family members were older than non-patient family members. For patient families, the mean age was 70.4 for husbands and 64.3 for wives. For non-patient families, the mean age was 64.2 for husbands and 57.3 for wives. Therefore we analyzed the data after we stratified the subjects based on the wife's age of 65. Patient families snacked less and 'dined out' less than non-patient families. However, they consumed cookies more frequently, and milk and fruits less frequently, when compared to non-patient families. There were no significant differences in nutrient supplementation, and/or instant food intake frequencies between patient families and non-patient families. Sixty-two percent of patient family members complained about health problems such arthritis, lumbago, numbness, shoulder pain, dizziness, and others, whereas 52olo of non-patient family members complained about Farmers' syndrome. Husband cigarette smoking was not significantly different among groups. However, the smoking patterns of the wives was significantly higher in patient families. Alcohol consumption was also higher in patient families. In summary, it was determined that rural patient families had poorer dietary behavior and poorer health in general, when compared to non-patient families, and accordingly, diverse community-level health and nutritional support are suggested to solve the farmers' health problems and to improve their quality of life.
