논 잡초 Echinochloa oryzicola(Vasinger) Vasinger와 E. oryzoides(Ard.) Fritsch의 국명 설정에 대한 제안
이정란(Jeongran Lee),김창석(Chang-Seok Kim),이인용(In-Yong Lee) 韓國雜草學會 2012 Weed&Turfgrass Science Vol.32 No.2
현재 국내에 분포하고 있는 논의 잡초중의 하나인 E. oryzoides (Ard.) Fritsch는 국명에 있어서 논피와 강피로 혼용되어 사용되고 있으며, 학명의 적용에도 혼란이 있다. 이에 산림청의 국립수목원과 한국식물분류학회에서 구성한 국가식물목록위원회에서 이미 합의된 국명인 "논피"의 통일된 사용을 제안하여 응용식물분야 연구자들에게 강피와 논피의 혼란을 피하고자 한다. 또한 학명의 적용 역시, E. oryzoides (Ard.) Fritsch와 E. oryzicola (Vasinger) Vasinger를 혼용하여 적용하고 있다. 그러나 그동안 국내에 알려진 논피의 학명은 E. oryzicola (Vasinger) Vasinger를 적용해야 하고, E. oryzoides (Ard.) Fritsch는 경남 마산에서 발견하여 보고한 미기록종인 "나도논피"의 학명으로 적용되어야 한다. Echinochloa oryzoides (Ard.) Fritsch is one of major troublesome weeds in the paddy fields in Korea. The Korean name and scientific name of the species has been controversial among researchers. The Korean names "Nonpee" and "Gangpee" are being used interchangeably and the application of its scientific name is being confused. The committee composed of the Korea National Arboretum and the Korean Society of Plant Taxonomists has agreed in the use of "Nonpee" as the Korean name. Therefore, we suggest to use the agreed name of the species for researchers to avoid confusion. In addition, the application of scientific names is also confused with E. oryzoides (Ard.) Fritsch and E. oryzicola (Vasinger) Vasinger. E. oryzicola (Vasinger) Vasinger should be applied to the known "Nonpee" and E. oryzoides (Ard.) Fritsch should be applied to the unrecorded "Nadononpee" discovered in Masan, Gyeongsangnam-do.

The growth of the online market has led to the growth of IT startups and the development of related derivative industries; however, such growth has also brought about new problems such as: (i) issues relating to the reinforcement of the superior bargaining position of the online platforms, the center of the market growth, and (ii) issues relating to the emergence of unfair trade practices. More specifically, examples of such issues include the following acts by online platform businesses: unilaterally altering contractual terms and conditions or suspending its services; transferring the return costs to users; intentionally exposing the platform businesses’ own products or its affiliates’ products as the top search result; and providing certain business users “most-favored customer clauses.” In order to resolve such problems, the EU and Japanese governments have enacted laws and regulations to regulate activities relating to online platforms and the Korean government is also in the process of enacting laws and regulations for this purpose. The reason for many countries to enact laws and regulations to regulate online platforms around the similar time would perhaps be due to the fact that the current laws and regulations in place are not sufficient to resolve the problems and issues arising from activities related to online platforms. The fact that online platforms are ever evolving in combination with various factors, however, is a reason for the new laws and regulations to be different in form from the current laws in place. This means that there should be a good balance between innovation and regulation. In Korea, the new bill pending legislation is based on the current structure of the Korean laws regulating unfair trade practices. However, the new bill is notable in the fact that it places an emphasis on preventative regulatory measures in order to promote the transparency of commercial transactions, and that it newly provides for separate criteria to determine what is the “superior bargaining position” in a commercial transaction. In comparison to the similar laws of other jurisdictions, the new bill is similar to other countries’ laws in that they emphasize the importance of preventative regulatory measures, but the new bill is also different in that it directly regulates unfair trade practices as well as sanctions for any violation. In this article, Author suggests that, in order for the new bill on online platform law to have its regulatory feasibility, the required fields of a contract, to be published through a public notice , should be limited to an appropriate extent and that specific standards should be provided for. In addition, Author further suggests that the concept of intermediary services should be interpreted with limitations in accordance with the purpose of the new bill. Last but not least, Author particularly proposes that the market should voluntarily change since the new bill has provided for a policy giving direction on the regulation of online markets.
Inverse effect of Nickel modification on photoelectrochemical performance of TiNT/Ti photoanode

Nanomaterial architecture with highly ordered, vertically oriented TiO₂ nanotube arrays shows a good promise for diverse technological applications. As inspired from the literature reports that Nickel modification can improve the photocatalytic activity of TiO₂, it was planned to coat Ni into the TiO₂ matrix. In this study, first TiO₂ nanotubes(TiNTs) were prepared by anodization (60V,3min) in HF-free aqueous electrolyte on ultrasonically cleaned polished titanium sheet substrates (1{times}7cm²). The typical thickness of the sintered TiNT (500?Cfor10min) was ~1 micronas confirmed from the FESEM study. In the next part, as-anodized and sintered TiNT/Ti photoanodes were used to coat Ni by AC electrodeposition from aqueous 0.1M nickel sulphate solution. During AC electrodeposition, conditions such as 1V DC offset voltage, 9V amplitude (peak-to-peak) and 750 Hz frequency were fixed constant and the deposition time was varied as 0.5 min, 1 min, 2 min and 10 min. The photoelectrochemical performance of pristine and Ni modified TiNT/Ti photoanodes was measured in 1N NaOH electrolyte under 1 SUN illumination in the potential range of -1V and 1.2V versus Ag/AgCl reference electrode. The photocurrent performance of TiNT/Ti photoanode decreased upon Ni modification and the results were confirmed after repeated experiments. This suggests us that Ni modification inhibits the photoelectrochemical performance of TiO₂ nanotubes.
