Neoporphyra kitoi Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi has been known as an endemic species in Japan. Its high temperature tolerance suggests that it could be advantageous for cultivation. In this study, we collected it from the Ulleungdo island, Korea and transferred it into Pyropia for a new combination, identified as Pyropia kitoi (Ma. Abe, N. Kikuchi, Tamaki, Tom. Sato, Murase, Fujiyoshi & Mas. Kobayashi) D.J. Kim, T.O. Cho & B.Y. Won comb. nov. based on morphological and molecular analyses. Pyropia kitoi is also reported as a new record species in the list of Korean macroalgal flora. Although we didn’t observe the emergence of new blades from the rhizoidal cells, which is a key character for this species, our molecular analysis of rbcL revealed that our samples from Korea were congruent with “Neoporphyra kitoi” from Japan and were nested within the clade of Pyropia. The gene sequence divergence between the Korean and Japanese samples was 0-0.2%.

Electronic waste (E-waste) has become a long-standing global concern. People are purchasing new affordable and improved technologies long before the end-of-life (EOL)’s of their old devices, which is leading to overconsumption and growing volumes of e-waste. At present, official data indicates that 80% of the volume of e-waste is not formally treated globally. The complex nature of e-waste recycling processes is a significant challenge.

Pamperpop is a new online platform based in Indonesia that connects beauty and personal care service providers to the end customers. The business idea was triggered by Zomato, an online platform for restaurant search and discovery service. There are some competitors in the market who provides services alike Pamperpop, but they are all new players who still building their customer base. This condition puts Pamperpop in a fierce competition and forces the company to be innovative in penetrating the market. Considering the nature of this business, there are two markets to be penetrated by the company. First market is the service providers who will become the tenant, and second market is the end customers who will become the user. Pamperpop has done some marketing activities to enter both markets; however the results were far from expectation. The acquisition rate did not meet target from management. Pamperpop really need to revisit their marketing strategy in order to stay competitive in the market. This article describes the analysis on the business issues faced by Pamperpop especially problems in the market penetration. Author identified the root issues by using Porter’s 5 Forces, Business Model Canvas, S-T-P analysis, and Marketing Mix. Authors found that management focus on the product development rather than identifying customer needs when building this business. This created some gaps in the marketing strategy to penetrate the market. The New Wave Marketing framework is chosen to formulate the new marketing strategy since it is suitable for technology and internet based business model that has horizontal communication in nature. The New Wave Marketing approach refines the existing business model to introduce clear positioning and strong differentiation in the market. The solution’s set aims to achieve Low Budget and High Impact marketing techniques with the combination of Above-The-Line and Below-The-Line approach.

Monopolistic mechanisms can be detected in China in many respects through Chinese internet monopolists would outperform their peers in the US or the EU by. The Chinese government endeavors to keep its Internet industry globally competitive and thus authorities involved in antitrust activities tend to tolerate the oligopolistic structure of the market. This is evidenced most obviously in the repression of competitors in certain fields, e.g., ‘Baidu,’ the ‘Chinese Google,’ in the field of IT-services – leading to a stricter regime of monopoly control in terms of substantial law. However, in the course of enforcement, various legal and practical challenges impede the efficiency of these measures. This paper analyses existing competition law enforcement and proposes effective application of antitrust law for its enforcement in the Internet industry under present Chinese law.

CFRP composites have high specific strength, specific stiffness, long fatigue life, light weight environmental safety characteristics. In this study, the mechanical properties are investigated through the compressive simulation analysis on the carbon fiber reinforced plastic sandwich. The experiment is carried out with the same condition as the analysis to verify the analysis result. One sandwich plate is composed with four layers. From the upper, this plate has the first, second, third and fourth layers due to the arrangement of angle direction. A plate has the symbol of [0/30/30/0] as the first, second, third and fourth layers due to the angle directions of 0°, 30°, 30° and 0°. There are the plates of [0/30/30/0], [0/60/60/0] and [0/90/90/0] in this study. The maximum compressive load becomes 53.139kN during the compression time of 12 sec in case of the plate of [0/30/30/0]. The maximum compressive load becomes 61.826kN during the compression time of 12 sec in case of the plate of [0/60/60/0]. The maximum compressive load becomes 53.002kN during the compression time of 12 sec in case of the plate of [0/90/90/0]. So, the plate of [0/60/60/0] endures the most load among three plates. The result of this study can be applied practically through the validation of experimental data on the simulation data. In this study, the mechanical characteristics are examined systematically through the impact analysis on the composite material of the carbon fiber reinforced plastic with aluminum foam by using the impact absorption due to CFRP plate.

High temperature deformation behavior of activated sintered W powder compacts was investigated. The compression tests were carried out in the temperature range between 900 and 110 at the strain rate of . The sintered specimens of Ni-doped submicron W powder compacts showed decrease in W grain size with increasing the Ni content. As the result, the flow stress was significantly increased with increasing the Ni content. We obtained Ni-activated sintered W compacts with the relative density of 94 l％and the average grain size of less than 5. A moderate true strain up to 0.60 was obtained without fracture even at 110 with the strain rate of for the activated W compact despite adding the 1.0 wt％Ni to submicron W powder.

The 2013 statistics showed that about 19 million automobiles were registered in Korea and, among these, ELVs amounted to about 770 thousands. Therefore, the Korean government imposed ELV recycling rate of 95% to be implemented by 2015 according to ‘Act on the Resource Circulation of Electrical and Electronic Equipment and Vehicles’. However, plastics and non-ferrous metal scraps arising from ELVs are not properly recycled with no adequate reuse: they are becoming major environmental concerns to overcome prior to the enforcement of ELV recycling in Korea. In view of this, contemporary ELVs recycling status in Germany is introduced in detail with main emphases on the legal context regarding efficient disposal and recycling management of ELVs & ASR as part of a preceding investigation into the state of the art example for future Korean recycling model.

추파연맥-옥수수 이모작 작부체계에서 헤어리벳치 녹비 이용의 가능성 및 그 효과를 검정하기 위해 1999년 및 2000년의 2년간 작물시험장 발포장에서 옥수수 수확 후 9월 초순 연맥과 헤어리벳치를 혼파하여 11월 초순 일차적으로 사초를 수확하고 난 후 월동한 벳치를 옥수수의 녹비로 이용하였을 때의 효과를 조사하였는데 다음과 같은 결과를 얻었다. 옥수수 단작에서 벳치단파에 따른 옥수수에 대한 2년 평균 벳치녹비량 6.7cm/ha의 효과는 연맥이모작의 옥수수 질소표준비와 거의 동일하였다. 연맥과 혼파시의 벳치의 녹비 및 녹비질소량은 벳치 단파시의 40%에 불과하여 옥수수 6엽기에 조사한 토양질산태 질소량도 벳치-녹비구 및 연맥-표준질소구보다 반 이하로 감소하였고 식물체 질소함량이 많이 감소하여 출사기 옥수수 질소흡수량이 40-50kg/ha 감소하였다. 그러나 옥수수 6엽기에서의 토양질산태 질소가 무질소비료구의 2배 정도였으며 시험 2년차에는 추비질소가 필요없이 토양 질산태 질소수준인 25mg/kg에 거의 접근하였으며, 출사기에서의 옥수수 질소흡수량이 무질소비료구보다 약 30-40kg/ha 증가하였다. 시험 1년차 연맥+베치-녹비구의 옥수수 전건물중은 벳치-녹비구 및 연맥-표준질소구보다 종실중이 다소 감소하여 약 2 ton/ha 정도의 수량 감소가 있었지만 시험 2년차는 동일하였다. 옥수수 1년차에 약 60kg/ha, 2년차에 20kg/ha 감소하였으며, 연맥-무질소구에 비해서는 1년차 30kg/ha, 2년차 45kg/ha 정도 증가하여 질소화학비료 50-100kg/ha 대체효과를 얻을 수 있었으며, 뚜렷한 녹비의 2년 누적효과를 볼 수 있었다. 따라서 옥수수의 단작시의 헤어리벳치녹비보다는 효과가 적지만 연맥 이모작시에도 연맥과의 혼파에 의한 헤어리벳치의 녹비 및 질소비료 절감효과도 충분히 크며 녹비의 누적효과도 기대할 수 있을 것으로 판단되었다.olice billeting area, sports area, and rear rest area. The entrance space, Podori plaza, and symbolic court on the south-west part of the site represent the publicity of the site as the concept of "open space." On the contrary, considering the specialty of police affairs, the north-east part of the site, which contains the police billeting area and rest area, were designed to maintain security by using the concept of "closed space." To express an identity of the KPA, ′Podori′, a police mascot, the plaza was designed and is suppose to function as the hub of the community. In the front section of the plaza, a symmetrical planting pattern, centering the strong axis, was introduced to strengthen its symbolic meaning. Traditional window frames such as the pattern of ′Pisal-jige′and ′′Umulsal-jige′ were used for the paving system which is applied as the environment friendly design. Site facilities and furnitrue were placed at every i
