역삼투의 공업적 응용은 최근 수처리 관계 뿐만아니라 식품 공업, 전자 공업, 약품 공업 및 유전자 공업에까지 그 범위가 넓어지고 있다. 현재 국내에서도 상당 수 보급되었고, 앞으로 점점 그 이용도가 증가하리라고 전망된다. 이와같은 역삼투에 대하여 지금까지 발표된 기본원리와 삼투막의 제조 및 성질을 논하고, 역삼투조작에 있어서 물질전달방정식과 유동방정식음 유도하고 이를 이용하여 역삼투조작의 처리용량과 분리능력을 추정할 수 있는 방법을 고찰하였다.

COVID-19 has challenged the pandemic response capability of many countries. Many governments around the world have imposed strict quarantine measures and border control to slow the spread of the virus. In the Philippines, the longest community quarantine has been imposed in the National Capital Region (NCR). However, the effectiveness of such measures is dependent on the cooperation of the public. The objective of this study was to gain an understanding of the knowledge, attitudes, and practices (KAP) of selected employees in the NCR. An online survey was conducted June 4-18, 2020, with 100 employed people living in the NCR. Frequencies and percentages were computed to describe the respondents' answers, and the Kruskal-Wallis test was used to determine the differences in the respondents' KAP levels according to selected demographic characteristics. Of those surveyed, 92% have a high knowledge of COVID-19. The respondents have a positive attitude toward the need for health education and the seriousness of COVID-19, as well as stricter measures against the pandemic, but are less positive in terms of how the government is responding to the pandemic. They also follow strict measures that will prevent the further spread of the virus. The results highlight the respondents' favorability of stricter government measures to control the spread of COVID-19, including the reimposition of an enhanced community quarantine in the NCR.

Background: Liver fluke infection is associated with cholangiocarcinoma; the bile duct cancer found frequently in the northeast and north of Thailand. Prevention and control particularly requires health education and behavior change. Objective: This study aimed to improve health behavior among village health volunteers (VHV) regarding liver fluke exposure in an epidemic area. Materials and Methods: A quasi-experimental study was performed during July 2015 to January 2016 in Sang Kha district of Surin province, Thailand. A total of 67 VHVs underwent a health education program (HEP) and data were collected on knowledge, attitude, and practice (KAP) before and after participation for HEP 3 months with a pre-designed questionnaire. The Students paired T-test was used for comparisons of mean KAP levels before/after the intervention. Results: The results revealed that knowledge (P-value=0.004), attitude (P-value=0.004), and practice level (P-value=0.000) were significantly improved after participation in the HBP. Attitude was significantly associated with knowledge (r=0.266, p<0.05), and practice (r=0.348, p<0.01). Conclusions: The implementation of health education among VHVs is feasible and increases their KAP. This improvement should have potential in liver fluke prevention and control in local communities in rural Thailand.

Objective: Angora rabbits fed a low-protein diet exhibit decreased hair production performance. This study was set out to evaluate the effects of methionine on hair properties and nitrogen metabolism in Angora rabbits fed a low-protein diet and to investigate the gene expression related to hair follicle development to determine the possible molecular mechanism of methionine effects on hair follicle development. Methods: An experiment was conducted to investigate the effects of DL-methionine addition on a low-protein diet on hair development in Angora rabbits. Angora rabbits were divided into 5 groups: fed a normal diet (control), fed a low-protein diet (LP), or fed an LP supplemented with 0.2%, 0.4%, or 0.6% DL-methionine (Met). Results: The results showed that rabbits in the LP group had lower wool yield than the control rabbits, but the addition of 0.4% to 0.6% Met to LP attenuated these effects (p<0.05). Dietary addition of 0.4% to 0.6% Met to LP increased the apparent nitrogen digestibility, nitrogen utilization rate, and feed efficiency (p<0.05). Feeding LP decreased the insulin-like growth factor 1 (IGF1), keratin-associated protein (KAP) 3.1, and KAP 6.1 mRNA levels compared with the control, but the addition of 0.4% Met in LP attenuated these effects (p<0.05). Relative to the LP or control group, dietary addition of 0.4% Met increased versican mRNA levels. Conclusion: In conclusion, the addition of Met to LP could improves wool production performance and feed efficiency and reduce nitrogen emissions in Angora rabbits. Met can promote hair follicle development, which may be associated with IGF1, KAP, and the versican signaling.

Heterotrimeric kinesin-2 is a molecular motor protein of the kinesin superfamily (KIF) that moves along a microtubule plus-end directed motor protein. It consists of three different motor subunits (KIF3A, KIF3B, and KIF3C) and a kinesin-associated protein 3 (KAP3) that form a heterotrimeric complex. Heterotrimeric kinesin-2 interacts with many different binding proteins through the cargo-binding domain of the KIF3s. The activity of heterotrimeric kinesin-2 is regulated to ensure that the cargo is directed to the right place at the right time. How this regulation occurs, however, remains in question. To identify the regulatory proteins for heterotrimeric kinesin-2, we performed yeast two-hybrid screening and found a specific interaction with creatine kinase B (CKB), which is the brain isoform of cytosolic creatine kinase enzyme. CKB bound to the cargo-binding domain of KIF3A but did not interact with the KIF3B, KIF5B, or KAP3 in the yeast two-hybrid assay. The carboxyl (C)-terminal region of CKB is essential for the interaction with KIF3A. Another protein kinase, CaMKIIa, interacted with KIF3A, but GSK3a did not interact with KIF3A in the yeast two-hybrid assay. KIF3A interacted with GST-CKB-C but not with GSK-CKB-N or GST alone. When co-expressed in HEK-293T cells, CKB co-localized with KIF3A and co-immunoprecipitated with KIF3A and KIF3B but not KIF5B. These results suggest that the CKB-KIF3A interaction may regulate the cargo transport of heterotrimeric kinesin-2 under energy-compromised conditions in cells.

The purpose of this study is to establish a method of estimating the daily urban water demand using statistical model. This method will be used for the development of the efficient management and operation of the water supply facilities. The data used were the daily urban water use, the population, the year lapse and the weather conditions such as temperature, precipitation, relative humidity, etc. Kwangju city was selected for the case study area. The raw data used in this study were rearranged either by month or by season for the purpose of analysis, and the statistical analysis was applied to the data to obtain the regression model. As a result, the multiple linear regression model was developed to estimate the daily urban water use based on the seather condition. The regression constant and the model coefficients were determined for each month of a year. The accuracy of the model was within 3% of average error and within 10% of maximum error. The developed model was found to be useful to the practical operation and management of the water supply facilities.

In order to increase the solubility and antibacterial activity of ampicillin, the lysinomethylene ampicillin trihydrate was synthesized. The blood concentrations of ampicillin trihydrate and synthetic lysinomethylene ampicillin trihydrate were determined in 10 healthy male volunteers by using large plate method with Sarcina lutea ATCC 9341. The mean blood concentration of synthetic lysinomethylene ampicillin trihydrate was higher ca. 1.3 times than that of ampicillin trihydrate in 10 test subjects after oral administration.
