After the adoption of the Lisbon Treaty, the European Union's Common Commercial Policy now belongs to the exclusive competence area of the EU, including the foreign direct investment (FDI) policy. Regarding the bilateral investment protection treaties (BITs) between the EU Member States, the European Commission is of the view that such BITs should be discarded. On March 6, 2018, the Court of Justice of the European Union (CJEU) held in the Achmea BV v. Slovakia case that a BIT between the EU Member States, as well as arbitral awards based on that BIT, is not subject to request for preliminary rulings under the Treaty on the Functioning of the European Union (TFEU), and thus they are not compatible with the EU law. However, the judgment did not silence the controversy. Instead, many people questioned the legal reasoning and the legitimacy of judgment, and therefore the problem is still ongoing.

An analysis of the 1/f or flicker noise in FD n-channel Double Gate SOI MOSFET is proposed. In this paper, the variation of power spectral density (PSD) of the equivalent noise voltage and noise current with respect to frequency, channel length and gate-to-source voltage at various temperatures and exponent $C(i.e\;1/f^c$ is reported. The temperature is varied 125 K from to room temperature. The variation of PSD with respect to channel length down to $0.1{\mu}m$ technology is considered. It is analyzed that l/f noise in FD n-channel Double Gate SOI MOSFET is due to both carrierdensity fluctuations and mobility-fluctuations. But controversy still exits to its origin.

There has been considerable controversy over the change of coastal topography and shoreline by coastal erosion in Gohyun Bay, Geojedo. In this study, we analyzed aerial photographs and surveyed coastal topography and shoreline. Changes between years were identified using a GIS overlay analysis and field surveys with DGPS, Total Station and Echo Sounder. As a result, we were able to identify changes by coastal erosion in the area of Gohyun Bay, Geojedo.

Objectives: To present the bases for health education on electronic cigarettes, we analyze the present state of electronic cigarettes. Methods: We applied descriptive study, reviewing the literature from domestic and foreign electronic databases such as National Discovery for Science Leaders and PubMed. Results: Electronic cigarette has been the subject of much controversy but very little study. I reviewed and summed up the definitions, device safety, health risk, smoking cessation effects, addiction, second hand smoke, and regulations of electronic cigarettes. Conclusion: Finally,I presented the evidence-based contents and desirable direction for health education about electronic cigarettes. The results suggested that the health educators focus on the potential addiction to electronic cigarettes, instead of the cessation effects.

During the past decade, substantial research effort has been directed into the development of rechargeable lithium batteries. Although some improvements in cycle life and efficiency have been achieved, the reversibility of the lithium electrode remains as a significant problem in aprotic solvent based electrolyte. The major problems limiting cycle life are short circuits resulting from growth of lithium dendrites, and macroscopic shape changes during the recharge process. As an anode material of lithium rechargeable battery, amorphous carbon materials have been studied extensively because of their high electrochemical performance. The polyacene materials prepared from phenol refine at relatively low temperature(550∼750$^{\circ}C$) show a highly Li-doped state up C$_2$Li state without liberation of Li cluster. So it has largely layered distance 4${\AA}$. The Li storage mechanism as well as the large hysterisis observed in the voltage-capacity profile of the amorphous carbone materials are still the subjects of controversy. We prepared each polyacene material various temperature and investigated electrochemical property. The mole ratio of [H]/[C] is 0.027∼0.015 range.

There are concern on possible health effects from exposure to electric and magnetic fields. One reflection of this concern is the considerable controversy, delay, and cost increases involved in the construction of utility lines and facilities. To meet such challenges, in this paper we investigated magnetic fields reduction techniqies such as general compaction, in-span compaction, cruciform, vertical, 3way splits phase, and 4way splits phase. As results, we found 1 spacer in-span compaction was appropriate in Korea in view of effectiveness and economy.

Helicobacter pylori (Hp), an important etiologic agent in a variety of gastroduodenal diseases, produces a large amount of urease, which is believed to neutralize gastric acid by producing ammonia for the survival of the bacteria. Up to 30％ of the enzyme is associated with the surface of intact cells by lysis of neighboring bacteria. However, the role of the external enzyme has been a subject of controversy, because the enzyme is irreversibly inactivated below pH 5.(omitted)

The Apiaceae genus Daucus consists of approximately 25 species (including carrots) which are characterized by the presence of bracts in pedunculate umbels, dorsally compressed mericarps, hairs on primary ridges, and uniseriately arranged spines on the secondary ridges of the fruit. Taxonomically, Daucus has been considered to be one of the most problematic genera in the Apiaceae due to the highly variable fruit morphology. Despite taxonomic controversy and economic importance of the genus, no rigorously constructed estimate of phylogenetic relationships exists. To examine generic limit and relationships among species of Daucus and its putatively related taxa, phylogenetic analyses of characters derived from nuclear ribosomal DNA ITS sequences were conducted. Two major clades emerged within Daucus, but neither of them have been previously recognized using morphological characters. The phylogeny also provides taxonomic status of recently reported new species of Daucus, D. arcanus and D. conchitae.

Objectives : To express an opinion on the controversy about the cold exposure as one of the risk factors of Bell's palsy. Results & Conclusions : It is widely assumed that there is a causal relationship between Bell's palsy and herpes family virus. Regarding cold exposure as one of the risk factors of Bell's palsy, however, some physicians do not accept that cold exposure could be one of the risk factors of Bell's palsy. There is no evidence supporting the hypothesis that the virus causes Bell's palsy, and it has yet to be confirmed. As there are some experimental and clinical reports suggesting that Bell‘s palsy is related to the cold exposure, we cannot exclude the possibility that the cold exposure may be one of the important risk factors of Bell's palsy. It would be necessary to undertake further studies to determine this.

Patients with chronic obstructive pulmonary disease receive a range of treatments including but not limited to inhaled bronchodilators, inhaled and systemic corticosteroids, supplemental oxygen, and pulmonary rehabilitation. Pulmonary rehabilitation is a multidisciplinary intervention that seeks to combine patient education, exercise, and lifestyle changes into a comprehensive program. Programs 6 to 8 weeks in length have been shown to improve health, reduce dyspnea, increase exercise capacity, improve psychological well-being, and reduce healthcare utilization and hospitalization. Although the use of pulmonary rehabilitation is widely supported by the literature, controversy still exists regarding what should be included in the programs. The goal of this review was to summarize the evidence for pulmonary rehabilitation and identify the areas that hold promise in improving its utilization and effectiveness.
