This essay tries to reveal the historical backdrop of basic income idea which has risen in recent years, because it is important to understand it in order to comprehend the basic income idea which seems to collide with the modern work ethic. Basic income idea has created three waves until the mid-twenties century. Thomas Paine and Thomas Spence proposed proto-basic income scheme based on the right of everyone to the Earth at the close of 18th century. Mable and Dennis Millners presented State Bonus Scheme as ‘a rational method of solving the social problem’ after the First World War. Those who organized Ad hoc Committee of Triple Revolution demanded ‘the unqualified right to an income’ as the suitable response to automation in the early 60s. These proposals were not realized interrupting by the idea of employed work and social welfare system based upon it, and then marginalized. Though nowadays basic income idea riding the forth wave has a bigger chance to be implemented than ever before. It is reason that we need a new solution to bring an income separated from employment, that is, the foundation of economic security for everyone before the prospect of social polarization, low-growth and automation.

<P>This letter presents a compact (0.12 x 0.14lambda) RFID tag antenna which has near-isotropic radar cross-section (RCS) patterns and easy conjugate impedance matching property by virtue of an inductively coupled feeding. Its measured maximum and minimum RCS' are -17.3 dBm<SUP>2</SUP> and -20.4 dBm<SUP>2</SUP>, respectively, with a difference of only 3.1 dB in all incident angles. The measured RCS' have been found to be in good agreement with simulation.</P>

It is important to manage artificial fish reefs with installation for restoration. we made survey for installation’s condition(location, amount etc.), fish community and amount of fishing net around installation area(6,142ha) of artificial fish reefs with side scan sonar and diving in Yeosu Coast of Korea. Number of the total installed and found artificial reefs is defined 46,872 and 39,003 (83.2%) artificial reefs, respectively. Observed artificial reefs is dominant dice type(19,663) and is the most of them in Geomun and Keumo islands. In addition, biological monitoring is shown that it is composed of fouling or settlement of marine communities in most of the artificial reefs. Most marine wastes around artificial reefs area are sort of the fishing gear such as net, rope, and fish trap. Also, marine wastes around artificial reefs are totally 41.82 ton less than 40 m depth in Yeosu.

본 논문에서는 유도결합 방식에 의한 무접촉 배터리 충전기의 시제품을 제작하고 그 실험결과를 보고한 것이다. 변압기의 유도결합 효율을 높이면서 높이를 낮추기 위해서 변압기의 1차측은 공심 코어 권선을 이용하였으며 2차측 권선은 플랙시블 다층 PCB를 이용하여 설계하였다. 시제품의 입력전압은 110/220V 공용이며, 사용된 배터리는 4.2V 700mAh급 리튬이온 배터리를 이용하였다. 특히 충전완료 시에 불필요한 회로동작을 제한하기 위해서 배터리 측에서 적외선 신호를 제공할 수 있도록 하였으며 시험결과 본 논문에서 제작한 시제품은 배터리를 완충하는데 약 45분 정도 소요되었다.

Robotic techniques can be one of the promised solutions to address the prostate cancer which is one of the most important public health problems in medical fields. Despite several past and on-going dedicated researches, the systematic techniques and completed theories have not been established well. Therefore we review the state-of-the-art literature on the applications of engineering technologies with particular focus on diagnosis and treatment of prostate cancer. The current status of the elastography and systematic DRE are presented as novel diagnostic tools, and an overview of the applied technologies to address the limits of the treatment (radical prostectomy and brachytherapy) is reviewed.

Parry Romberg Syndrome (PRS), also known as idiopathic progressive hemifacial atrophy, is a rare neurocutaneous disorder characterized by loss of skin and subcutaneous fat of face, muscles, and bones causing unilateral atrophy. Most patients require only soft tissue augmentation although syndrome has varying grades of severity. In the majority of reported cases, it has been treated with surgical flap or autologous fat transplantation. However, these treatments need complicated surgical skills which take a lot of time and cost. Herein we report the first case of PRS augmented by hyaluronic acid (HA) filler in a 42-year-old female patient to suggest that HA filler could be a safe, simple, and even rational economic alternative to surgical treatment.

Background: Tranexamic acid (TXA), a plasmin inhibitor, has been used orally or via intradermal injection to treat melasma; however, there are limited studies regarding efficacy and safety of topical application of TXA. Objective: The purpose of this study is to evaluate the efficacy and safety of topical tranexamic acid in treatment of melasma. Methods: We enrolled 25 female volunteers with melasma in a split-face trial lasting 10 weeks. Patients were instructed to apply cream containing tranexamic acid on only the right side of their face every night without application on the other side. The pigmentary index (PI) using API-100 and Melasma Area and Severity Index (MASI) were measured at 0, 5, and 10 weeks. Patient satisfaction questionnaires and safety evaluation by a dermatologist were performed at each follow-up visit.== Results: Twenty-five patients completed the study, and we noted reduction in both, mean MASI and PI scores. The mean MASI score was 7.75±5.10 at baseline, 6.72±4.25 at week 5, and 6.26±3.76 at week 10 p=0.008). The mean PI score on the right side of the face was 40.56±22.51 at baseline, 29.96±16.62 at week 5, and 26.88±15.97 at week 10. The PI on the right side of the face decreased by 26.1% (p<0.001) at week 5 and 33.7% (p<0.001) at week 10 compared to the baseline. Mean PI score on the unaffected side of the face was 40.56±22.60 at baseline, 37.48±17.79 at week 5, and 34.68±16.44 at week 10, although this reduction was not statistically significant (p=0.146). Only mild irritation occurred in two patients, no other serious adverse events were noted, and patients were generally satisfied with their results. Conclusion: Topical TXA can be considered a safe and effective option in the treatment of melasma. (Korean J Dermatol 2017;55(5):283∼289)
