The first local exchange trading system(LETS), established in Comox Valley in Canada, aimed at facilitating the regional economy. However, in Korea, LETS was adopted to encourage mutual aid and promote community spirit among residents. This study examines the feasibility of LETS as a revitalization initiative for Pumasi and suggests a number of policies that can be implemented to support the project. The findings are as follows: First, the LETS credit system was found to complement social capital initiatives among Pumasi participants in the early stages of the Pumasi project. Second, combining LETS and Pumasi initiatives was found to consolidate community spirit and encourage a cooperative way of life among participants due to the fact that LETS enlarges the scope of local residents' participation and diversifies the services being exchanged. A number of policy suggestions are made for combining LETS with Pumasi. First, the project must define a vision of its long-term purpose and outcomes. Second, local residents should be employed as assistants to facilitate the project. Third, Pumasi participants should ensure that childcare exchange services are of the highest quality by providing an educational program on parenting. Fourth, the project manager's employment conditions and working environments must be guaranteed.

Completion of the human genome project has allowed a deeper understanding of molecular pathophysiology and has provided invaluable genomic information for the diagnosis of genetic disorders. Advent of new technologies has lead to an explosion in genetic testing. However, this overwhelming stream of genetic information often misleads physicians and patients into a misguided faith in the power of genetic testing. Moreover, genetic testing raises a number of ethical, legal, and social issues. Diagnostic genetic tests can be divided into three primary but overlapping categories: cytogenetic studies (including routine karyotyping, high-resolution karyotyping, and fluorescent in situ hybridization studies), biochemical tests, and DNA-based diagnostic tests. DNA-based testing has grown rapidly over the past decade and includes preandpostnatal testing for the diagnosis of genetic diseases, testing for carriers of genetic diseases, genetic testing for susceptibility to common non-genetic diseases, and screening for common genetic diseases in a particular population. Theoretically, once a gene's structure, function, and association with a disease are well established, the clinical application of genetic testing should be feasible. However, for routine applications in a clinical setting, such tests must satisfy a number of criteria. These criteria include an acceptable degree of clinical and analytical validity, support of a quality assurance program, possibility of modifying the course of the diagnosed disease with treatment, inclusion of pre-and postnatal genetic counseling, and determination of whether the proposed test satisfies cost-benefit criteria and should replace or complement traditional tests. In the near future, the application of genetic testing to common diseases is expected to expand and will likely be extended to include individual pharmacogenetic assessments.

The International Standard Banking Practice for the Examination of Documents under UCP 600 (ISBP 745) is the product by the Drafting Group of the ICC Banking Commission during a number of years. ISBP 745 is a practical complement to UCP 600, ICC's universally used rules on documentary credits. ISBP 745 does not amend UCP 600. Two rules should be read in their entirety and not in isolation. ISBP 745 explains, in explicit detail, how the UCP 600 rules are to be applied on a day-to-day basis. It fills a needed gap between the general principles announced in UCP 600 and the daily work of the documentary credit practitioners. It has developed into an invaluable aid to banks, corporates, logistics and insurance companies alike, on a global basis. By using ISBP 745, document checkers can bring their practices in line with those followed by their colleagues worldwide. The result should be a significant reduction in the number of shipping documents refused for discrepancies on first presentation. This study aims to summarize the reasons for revision of the ISBP rules and the key-points of ISBP 745, and to provide the documentary credit practitioners with some considerations under its practical application.

Purpose: This study was to investigate the prevalence of depressive symptoms and risk factors in elderly people (old vs oldest-old) with arthritis. Methods: The Korean Longitudinal Study of Aging (KLoSA) was used with a sample of 1,084 elderly people with arthritis aged 65 or above. Results: We found that the prevalence of depressive symptom was greater for oldest-old people (66.7%) compared to old people (56%). Significant differences between old people and oldest-old people were found for education, living with spouse, number of generation, regular exercise, body mass index (BMI), ADL limitation, self-rated health, and depression. Significant differences existed between depression and non-depression in terms of all variables except region and BMI among old people. But, among the oldest people, ADL limitation and self-rated health showed differences. The Logistic regression analysis revealed that religion, medical comorbidity, ADL limitation, self-rated health were significantly associated with depressive symptoms in old people. But, in oldest-old people, none of the variables were associated with depressive symptoms. Conclusion: The findings show that there are age differences in depression and related factors in elderly people with arthritis. Longitudinal studies, which covered depressive symptom severity and which are controlled for a large number of potential confounders, will need to complement the results of this study in the future.

Karyotypic analysis and FISH (fluorescence in situ hybridization) with 45S and 5S rRNA genes were carried out in Persicaria tinctoria H Gross. The somatic metaphase chromosomes were ranged from 2.25 ${\mu}m$ to 1.50 ${\mu}m$ in length. Chromosome number was 2n = 4x = 40 with the basic number of x = 10. The chromosome complement of the species consisted of 16 pairs of metacentrics (chromososomes 1,2,3,4,6,7,8,9, 10, 11, 12, 13, 15, 18, 19 and 20) and 4 pairs of submetacentrics (chromosome 5, 14, 16 and 17). The karyotype formula was K(2n) = 4x = 32 m + 8 sm. In FISH analysis, three pairs of 45S rRNA gene loci on the terminal region of submetacentrics (chromosomes 5, 16 and 17) and two pairs of 5S rRNA gene loci on the centromeric region of metacentrics (chromosomes 9 and 11) were detected, respectively.

This study is about spin half add operations in 𝓑₂ and 𝓑₃. The burden of technological structures has increased due to the increase in the use of today's technological applications or the processes in the digital systems used. This has increased the importance of fast transactions and storage areas. For this, less transactions, more gain and storage space are foreseen. We have handle tit (triple digit) system instead of bit (binary digit). 729 is reached in 3⁶ in 𝓑₃ while 256 is reached with 2⁸ in 𝓑₂. The volume and number of transactions are shortened in 𝓑₃. The limited storage space at the maximum level is storaged. The logic connectors and the complement of an element in 𝓑₂ and the course of the connectors and the complements of the elements in 𝓑₃ are examined. "Carry" calculations in calculating addition and "borrow" in calculating difference are given in 𝓑₃. The logic structure 𝓑₂ is seen to embedded in the logic structure 𝓑₃. This situation enriches the logic structure. Some theorems and lemmas and properties in logic structure 𝓑₂ are extended to logic structure 𝓑₃.

DC servo motors have a defect that they need a periodical maintenance because of a brush commutation and also they have a difficulty at high speed operation. In this reason, the use of AC Servo motors are increasing these days. In this paper, a proposed neuro observer is applied to speed control of AC servo motor. The proposed observer complement a problem that occur from increase of gain of High-gain observer in proportion to the square number of observable state variables. And also, the proposed observer can tune the gain obtained by differentiating observational error automatically by using the backpropagation training method to stabilize the observational speed. The excellence and feasibility of the proposed observer is proved by making a comparison test between the proposed observer and the others applied to the same AC servo motor.

In searching for anticomplementary compounds, three phenylpropanoids were isolated from the roots of Agastache rugosa and identified as rosmarinic acid (RA), rosmarinic acid methyl ester (RAM) and caffeic acid methyl ester (CAM) by NMR analyses. RA and RAM exhibited strong inhibitory activity on both the classical pathway (CP) and the alternative pathway (AP) of the complement system, in vitro, but CAM did far less than RA and RAM. $RAM-M1{\sim}-M5$, the methylated derivatives from the RAM, showed that the inhibitory activity was decreased in inverse proportion to the number of methylated groups and $RAM-M 2{\sim}-M4$, the isomers of two methylated hydroxyl groups, exhibited different inhibition activity.

The ability to recover the nearly limitless supply of uranium contained within the world's oceans would provide supply security to uranium based fuel cycles. Therefore, in addition to U.S. national laboratories conducting R&D on a system capable of harvesting seawater uranium, a number of collaborative university partners have developed alternative technologies to complement the national laboratory scheme. This works summarizes the systems analysis of such novel uranium recovery technologies along with their potential impacts on seawater uranium recovery. While implementation of some recent developments can reduce the cost of seawater uranium by up to 30%, other researchers have sought to address a weakness while maintaining cost competitiveness.

We find a $C^{\infty}$-continuous path of Riemannian metrics $g_t$ on $\mathbb{R}^k$, $k{\geq}3$, for $0{\leq}t{\leq}{\varepsilon}$ for some number ${\varepsilon}$ > 0 with the following property: $g_0$ is the Euclidean metric on $\mathbb{R}^k$, the scalar curvatures of $g_t$ are strictly decreasing in $t$ in the open unit ball and $g_t$ is isometric to the Euclidean metric in the complement of the ball. Furthermore we extend the discussion to the Fubini-Study metric in a similar way.
