Natural safflower oleosomes are small ($1{\sim}3{\mu}m$) spherical shaped "reservoir", inside which the seed stores triglycerides for use as a future energy source. The surface of the oleosome is covered with a high molecular weight ($20{\sim}24$ KDa) oleosin protein which has been demonstrated to have emulsification properties. Traditionally, oleosomes from oil bearing seeds such as safflower were simply crushed to liberate the oil within. Our patented DermaSphere technology allows for the isolation of oleosomes in the intact state. Once isolated, these materials can be used in skin care formulations to deliver the emolliency, occlusivity, and anti-oxidant effects typically associated with safflower oil. However, because of the presence of the emulsifying oleosin protein covering the spherical oil body, oleosomes have self-emulsification property as well as can emulsify other oil phase in typical oil-in-water (O/W) emulsion. The oleosomes can literally serve as the entire non-active portion of the oil phase of a typical skin care product. Most importantly, natural oleosomes can be loaded with other oil-soluble active materials and can therefore be used as delivery systems for improved cosmetic efficacies. Oleosomes can be loaded with various actives, such as fragrances, vitamins, inset repellents, and UV chromophores. The loaded oleosomes can be utilized to either protect the active ingredients within the formulation itself or to allow for control release of those actives over time.

This paper analyzes the concept of Lacanian subject and the structural definition of sexual difference between man and woman, and criticizes some problems of those definitions. It seems to me, to do so, that it is important to know precisely the core terms of psychoanalysis quoted by Lacan. We should analyze the basic meanings and the relation of the Imaginary, Symbolic and the Real, of ideal ego and ego ideal, of phallus and signifier, of desire and the other, of consciousness and unconsciousness, of alienation and separation, etc. I'm going to discuss the relation between the Imaginary and the ideal ego in chapter 2, and then, deal with the relation between the Symbolic and the ego ideal in chapter 3. I'll explain both similarity and difference between the ideal ego and ego ideal through those discussions. In chapter 4, I'm planning to explain the relation among the other, desire and the subject of unconsciousness. In chapter 5, I'll analyze the meaning of phallus and signifier. I'll criticize the Lacanian structural definition of sexual difference on the basis of the work made in former chapters. These discussions will lead to my final conclusion that the concept of Lacanian subject and the structural definition of sexual difference are only dependent on reductionism regarding everything as symbolic, which has in itself a lot of contradiction. In order that All discussions about sexual difference have at least a objective meaning, they have to rely on anatomical differences between man and woman.

The results of electron microscopic studies on the cell fine structure of Nocardia sp the location of tellurite-reducing enzyme and the reduction part of T. T. C. (Triphenyl tetrazonium chloride) were summarized as follows. As the fine structure of the cell, the membrane-like structure with unit membrane was distributed in the cytoplasm. The membrane-like structure had complicate forms: some of membrane-like structure appeared spiral form. As the metal tellurium salt appeared in the cytoplasm, it is obvious that tellurite and tellurate-reducing enzymes are present in the cytoplasm. Reduction of T. T. C. took place in the cell membrane and the intracellular membrane-like structure. Therefore, it was thought that reduction of tellurate and T. T. C. took place in different parts. T. T. C. formazane formed in the cell was reoxidized by osmic acid which was used as a fixation reagent for the electron microscopic specimen preparation. As 95％ T. T. C. formazane was soluble in ethanol and embedding materials and removed out of the cell, an originally formed formazane appeared as electron light part on the electron microscopic image.

The DFA(detrended fluctuation analysis) which is included the correlation property of the EEG is used to analysis the depth of anesthesia. We studied ASA I or II adult patients supported by the society of anesthesiologists. Patients with history of dementia and neurological disorder are excluded. Average age is $48.9{\pm}10.9$ old, average weight is $57.1{\pm}8.2$ kg and average hight is $158{\pm}6.6$cm of the patients under the operation. Anesthesia medicine is Sevoflurane and the stages of anesthesia are 6 stages, that is pre-operation, induction, right after induction, stop the medicine and post-operation. Among the scaling exponent ${\alpha}1$, ${\alpha}2$, ${\alpha}3$ we know that ${\alpha}1$, ${\alpha}3$, were well appeared to discriminate pre-operation, induction, right after induction, stop the medicine and post-operation. So we confirmed that the parameters is useful to the depth of anesthesia.

Recently, the capacity of video content delivery services has been increasing significantly. Therefore, the importance of user recommendation is increasing. In addition, these contents contain a variety of characteristics, making it difficult to express the characteristics of the content properly only with a few keywords(Elements used in the search, such as titles, tags, topics, words, etc.) specified by the user. Consequently, existing recommendation systems that use user-defined keywords have limitations that do not properly reflect the characteristics of objects. In this paper, we compare the efficiency of between a method using voice data-based subtitles and an image comparison method using keyframes of images in recommendation module of educational video service systems. Furthermore, we propose the types and environments of video content in which each analysis technique can be efficiently utilized through experimental results.

The purpose of this article is to explain the conceptual changes that the notion of Haewon (解冤) has undergone by examining the evolution of the usages of Haewon. In order to achieve this purpose, I reviewed the conceptual connotations and denotations of Haewon contained in data from the Joseon Dynasty (Section 2), the Japanese colonial period (Section 3), and the scriptures and major preceding research of Daesoon Jinrihoe (Section 4). The research results described in this article are as follows. First, Haewon is a term with historical, social, and cultural characteristics. This means that Haewon, a term that has been used since the Joseon Dynasty, was a concept used to solve collective problems but could also be applied on the individual level. This further means that, if culture is regarded as a collective consciousness or as a collection of material products, Haewon would be a term that contained social and cultural aspirations. Second, Haewon is not a concept that has been impervious to innovation throughout its history. This can be confirmed by the fact that Haewon's scope of application has changed depending on the problem domain (legal, natural disasters, an institutional domain, etc.). Third, Haewon has converted into religious language a doctrinal system that came about after the emergence of Jeungsan. This means that previously the concept of Haewon was mainly used at the legal level in the Joseon Dynasty, but after the emergence of Jeungsan, it became a term in religious language and in doctrine. The materials of Daesoon Jinrihoe show that this concept of Haewon was expanded to be included at the doctrinal level. These research results show a historical shift in the ideological thought contained in the concept of Haewon. As a term in religious language that is included in a doctrinal system, Haewon has an extension of denotations that is applied to the world beyond individuals and societies, yet it maintains connotations of resolving grievances. This concept of Haewon mediates the transformation of the world and creates a rationale by which training and ethical practice are necessary components of that process of transformation.

A technique for the determination of trace Cu(II) in various real samples by FAAS after the column preconcentration onto p-dichlorobenzene-SA adsorbent, which is microcrystalline p-dichlorobenzene loaded with salicylaldoxime (SA) has been developed. Several experimental conditions such as pH of the sample solution, the amount of chelating agent salicylaldoxime, the amount of adsorbent p-dichlorobenzene-SA, and flow rate of sample solution were optimized. The interfering effects of various concomitant ions were investigated. $CN^-$ interfered more seriously than any other ions. However, the interference by $1\;{\mu}g\;mL^{-1}\;CN^-$ could be overcome completely by controlling the concentration of Ni(II) to $20\;{\mu}g\;mL^{-1}$. The linear range, correlation coefficient ($R^2$) and detection limit obtained by this technique were $3.0\sim100\;ng\;mL^{-1}$, 0.9901, and $3.1\;ng\;mL^{-1}$, respectively. For validating this technique, the aqueous samples (wastewater, reservoir water and stream water) and the food samples (orange juice, fresh egg and skim milk) were used. Recovery yields of 93~104% were obtained. These measured mean values were not differents from ICP-MS data at 95% confidence level. The good results were obtained from the experiments using the rice flour certified reference material (CRM) sample. Based on the experimental results, it was found that this technique could be applied to the preconcentration and determination of Cu(II) for various real samples.

Chemicals are an indispensable element of modern society to the extent that more than 15 million species are commercially available worldwide. However, among them are chemicals whose toxicityposes a threat to public health and the environment, as illustrated by past cases of chemical accidents, which revealed their danger to human life. Chemical accidents can spread and cause huge damage in a short time because of their characteristics. Therefore, it is important to do as much as possible to prevent them in advance and to respond promptly after an accident. The legal system pertaining to domestic chemical substances is the "Toxic Chemical Control Act", which is made up of the "Act on the Registration and Evaluation of Chemicals" and the "Chemical Control Act" since 2015. Under this law, the Comprehensive Chemical Information System and Chemical Substance Data Processing system were established and are still operating;however, chemical accidents are still occurring. These systems are comprehensive information systems aimed at providing chemical information rather than acting as chemical response systems, which has limited the effectiveness of accident response. This study is intended to analyze the information management systems, response management systems and the basis of chemical substance management support for hazardous chemicals and suggest ways to improve the legal system for developing and operating chemical response systemswithin a municipality.

This discussion can be said to be a qualitative study on the possibility of linking communication education for college students and literacy education for Korean language-linked educators based on the theory of interpretation of cognitive meaning of media text containing complex mechanisms. The implicit meaning of media content expression used as an interactive communication strategy will be accepted as a multilateral interpretation according to the individual learner's cognitive environment. If so, how is the general media content meaning intended by the content creator being accepted? These doubts are the starting point for discussion. To solve the problem, I leaned on the experimental pragmatic methodology of cognitive aesthetics and applied a model of relevance of cognitive linguistics to connect learners' creative cognitive environment and present content to find a contrast. As a result of the discussion, it was possible to establish a basic framework for learners to express their subjectivity and creative thinking that could connect the cognitive environment and present content themselves. In particular, active and positive learners also revealed direct descriptive expressions to build a new cognitive environment, such as suggesting a third alternative to argue the ability to question produced media texts and the validity of the meaning implied in the text. In the future, since media text containing complex mechanisms is an indirect and persuasive communication behavior that occurs easily through various media in modern society, the universal communication principle of reliable conversation between media text creators and audiences should exist.
