Purpose In the procedure of domestic medical radioactive self-disposal, there are many requests of supplementation and difficulties on the screening process. In this regard, presentation of basic guideline will improve the work processing efficiency of medical institution radioactive waste. From 2015 to 2016, We reviewed and compared a supplementary requests of domestic fifteen medical institution radioactive self-disposal Plan & Procedure manual. In connection with this, we derive the details of the radioactive waste document based on the relative regulation of nuclear safety Act. The representative supplementary requests of Korea Institute of Nuclear Safety are disposal method of non-flammability radioactive waste, storage method of scheduled self-disposal waste, the legitimacy of self-disposal and pre-treatment of self-disposal, reference radioactivity of disused filter and output of storage period, attachment the evidential matter of measurement efficiency when using a gamma counter. Through establishing a medical radioactive waste guideline, we can clearly suggest a classification standard of radioactive nuclide and the type of occurrence. As a result, we can confirm the reduction of examination processing period while preparing a self-disposal document and there is no spending expenses for business agency. Also, the storage efficiency of facility will better and reduce the economic expenses. On the basis of this guideline, we will expect a contribution to the improvement of work efficiency for officials who has a working-level difficulty of radioactive waste self-disposal.

The propagation of Infectious Diseases is very dreadful. It is not easy to detect through whom and where Infectious diseases start. Due to traffic development, these days, viral infectious diseases that weren't known in Korea in the past sometimes emerge in Korea, that is, probability to be propagated by certain viral infectious disease is getting bigger and bigger. The prevention of infectious diseases should be thoroughly blocked before they are introduced, nevertheless, when introduced, the government has a duty and responsibility to prevent them from spreading as soon as possible. There may be a terrible case that a certain infectious disease is spreading all over the world. Of course, in this case, cooperation between countries becomes more and more important than ever. But even in this situation, the nation's role should not decrease. Quarantine Law in Korea says that the government can take a quarantine measures to minimize the risk of infection. So the government can isolated questionable people with the risk of infection as well as people with the risk of infection. Quarantine or Isolation is a quite effective measures to prevent the viral infectious disease, however, it allows all subjects' right of freedom to be restricted. So, in any case that a infectious disease is spreading quickly, the probability for subjects to be isolated unreasonably or preposterously can probably happen. In this paper, I'll consider and discuss about the harmony between Public Health and Human Rights through quarantine or isolation.

Piracy is the enemy of the human race. Pirates commit acts of murder, robbery, plunder or other villainous deeds at sea, cruelly against humanity. The Republic of Korea(ROK), as a big maritime country, is obliged to suppress piracy under international treaties it ratified, including the UN Convention on the Law of the Sea and the two 1988 Conventions against maritime terrorism The Korean government is recently taking a positive attitude towards the regional cooperation which is necessary for the suppression of piracy in the waters of Southeast Asia In spite of the effects of international cooperation to prevent piracy, it is recently on an increasing trend every year. Such circumstances may have a bad effect on the sound development of world economy by means of trade at sea as well as treat to the safety of crews and safe operation of ships. This paper aims to suggest the countermeasures against piracy in terms of criminal law, civil law and international law in order to secure safe operation of vessels at sea.

[ $BaZrO_3$ ], nanopowder was added to YBCO powder to make ($BazrO_3)_x(YBCO)_{(100-x)mol.-%}$ ($BZO_x$-YBCO) ($0{\leq}x{\leq}10$) composite targets fur pulsed laser deposition of superconducting layer in order to investigate the effect of the addition of BZO nanopowder in the YBCO target on the flux pinning properties of $BZO_x$-YBCO thin films. All the $BZO_x$-YBCO thin films were grown on single crystal STO substrate under similar conditions in the PLD chamber. The effect of YBCO targets doped with BZO on the flux pinning properties of $BZO_x$-YBCO thin films has been investigated comparatively. The isothermal magnetizations M(H) of the films were measured at temperatures between 5 and 80 K in fields up to 5 T, employing a PPMS. The optimal amount of BZO nanopowders in $BZO_x$-YBCO thin films to obtain the strongest flux pinning effects at high magnetic fields is about 6 mol.-%.

According to disclosure regulation, insider can hide their trading until disclosure day, because there be interval between trading time and disclosure time. To accommodate strategic trade, they have an incentive to be brought disclosure interval as long as possible. This research investigate whether strategical behaviour of informed traders using disclosure intervals exists in domestic stock market.ls xt, we aney he whether they can get abnormal return through stealth strategy after announcement date. We also evaluate the effect of mimicking trading on price impact with the assumption of existence of mimicking trading. Our major research results are as follows: In case of main shareholder without having no prompt disclosure duty, the frequency of trading started at the beginning of month is shown significantly higher than others. This result shows a direct evidence that informed traders buy or sell their equity strategically using disclosure intervals. Also, we find the result that the coefficient of strategic variables has highest value in middle size information. However, the empirical evidence that informed trader get abnormal return through strategic trading was not shown in this study. Meanwhile, stock price over-reacts for selling transaction on trading point and is recovered after disclosure date., so we assume possibility of mimicking trading exists in domestic stock market.

The study uses the image technique of the movie (analysis) since there are limited analyses and data of the dance film's (cinematic) grammar. The films are limited to the Wim Vandekeybus's Blush. From the analysis of the one film, films are directed using basic movie grammars. Although the films are of the same genre, it differs from the method of using image techniques as well as the director's personal art preference. The cinematic grammars enhance the effect of the movement and it emphasizes the objectives to deliver the audience true meaning of the films. Dance film is not a simple word combination of dance and film to record new type of art; dance is used for the movie's artistic and aesthetic enhancement. To find out dance is the language and important expressive tool of the dance film, at the same time cinematic grammar enhances effect of dance and objective of the film, the study uses image technique analysis. These are the results of dance film analysis by using image techniques. Firstly, Dance film can transcend time and space. Secondly, The creative director could emphasize some part that the audience should focus on to clearly deliver the intention of the choreographer. Lastly, To popularize the dance genre. If the dance film produces with more diversified stories than the resent, it will be a part of a cultural industry and could create profits. Dance film might lose the sense of realism, which is the main characteristic of the stage art; however it could feel the beauty of the film through the mise en scene.

The need for seawater desalination is increasing in terms of securing various water resources, but few studies are available as for the environmental impact of hypersaline concentrated water (brine) discharged from desalination plants. Domestic studies are concentrated mainly on toxicity evaluation that phytoplankton, zooplankton larvae and green algae (Ulva pertusa) are negatively affected by concentrated water. The mortality of Paralichthys olivaceus showed a linear relationship with increasing salinity, and Oryzias latipes died 100% at concentrations above 60 psu. Foreign studies included monitoring cases as well as toxicity evaluations. The number of species decreased around the area where the concentrated water discharged. The hypersaline concentrated water affects the pelagic and benthic organisms. However, the fishes escaped when exposed to salinity, and the pelagic and benthic organisms resistant to salinity survived the hypersaline environment. The salinity limit and distance from the outlet was presented as the regulatory standard for bine discharge. There were differences in regulatory standards among country and seawater desalination plants, and these regulatory standards have been strengthened recently. In particular, California Water Boards were revised to ensure that the maximum daily salinity concentration does not exceed 2 psu above the ambient salinity level within 100 m of the outlet.

The successful performance ability of the private security of a bodyguard is evaluated as the quality of the bodyguard. However, the performance ability of a bodyguard is never decided only with his/her ability. When the educational development of a security company is continuously made, bodyguards and their team belonging to the company can obtain a good evaluation. It is also directly connected with the recognition of a company that plays the role of CP. A fundamental repetition education over safety and happiness should be conducted to avoid the lack of safety awareness under genuine recognition. Security companies should surely understand that liberation from the uneasiness for unclear future is not achieved only with the skill and ability of a bodyguard. The ability of a single bodyguard does not represent his/her team. The security of a client is maintained with a satisfying result of a team. The satisfaction result of a client should be linked to a result to improve the personal satisfaction of a bodyguard. When a security company and its CEO support an education that rightly regulates the activities of a bodyguard, the quality of a bodyguard and the satisfaction of his/her team obviously improve together. This research aims at being used as educational material that is needed for maintaining the psychological condition of a client while guarding the client. This is because the method accessing the excellent performance ability of a bodyguard needed by a client can be achieved through education.

In this paper I will try to show how Wittgenstein criticized Frege's theory of meaning. Frege's theory of meaning can be compressed as sense-reference theory. Frege distinguishes between sense and reference on all the linguistic expressions. In particular, he regards that a sentence has sense and reference. This distinction was raised from, so to speak, the problem of identity sentences. Wittgenstein's "fundamental thought" of Tractatus Logico-Philosophicus is the key of his direct criticism of Frege's sense-reference theory. That is, it is an attack on Frege's thought that the reference of a sentence is a truth value and truth values are "objects themselves" (in Frege's meaning). According to Wittgenstein, such an object does not exist and according to his picture theory, the function of a name and that of a proposition are fundamentally different. By the way, Frege can reply justly to this criticism that it is insufficient. In short, Frege's 'sense' and 'reference' etc, are the technical terms. Hence Wittgenstein's decisive criticism of Frege's theory consists in accusing his theory of logical flaws. There is an another route to the sense and reference of a sentence which Frege introduces. In discourses of judgement stroke and content stroke in his Begriffsshrift and in those of horizontal stroke since his "Function and Concept", Frege deals with the sense and reference of a sentence. Wittgenstein criticize that the sense of a complex sentence such as ~p would by no means be determined by Frege's determination.
