The purpose of this study is to analyze the spatial-temporal proliferation of individual factories in the Seoul Metropolitan Area and to provide policy implications. The location of the factory is divided into individual locations and planned locations. In the case of individual locations, it takes a long time to establish factories. Also, due to high cost and regulation, the establishment of individual factories is not easy. However, since the establishment process is simple and the price of land is low, the establishment of individual factories has led to an increase in the number of individual factories. The problem of the undeveloped factories is that the lack of infrastructure such as the road and environmental pollution treatment facilities around the factory deteriorates the pleasant environment and the cityscape and deteriorates the health of the residents in the surrounding area. In this study, we analyzed the location of individual factories established in the Seoul metropolitan area from 2001 to 2016 by using ArcGIS Pro. The results of the analysis are as follows. First, individual location factories are formed around existing industrial complexes and industrial sites. The reason for this is considered to be the external effect that can be obtained from the surrounding area. Secondly, since the Seoul city's individual location factories are established in many residential areas, it shows the conflicting result of the mixture of residence and factory. Third, the Gyeonggi province's individual location factories have a high proportion of non-urban areas. This is because the Gyeonggi province's management area occupies a larger proportion than other areas in Gyeonggi province. This study analyzed the spatial - temporal spreading process of individual factories and the unfolding of individual factories in the metropolitan area, and it can provide policy implications to control the over development of individual factories in the future.

In this study, we investigated effects of Monegy (mixture of Sophorae Radix, Panax ginseng, Salvia miltiorrhiza BUNGE) on epilate-induced hair-loss in dorsal region of C57/BL6 mice and external structure of human hair. For morphological and histological analysis in scalp of epilate-induced hair-loss animal model, we utilized several microscopic techniques, such as confocal laser scanning microscopy (CLSM) and LAS 4000. Confocal analysis showed the distribution of FITC-conjugated Monegy and penetration depth compared with normal and control group. Furthermore, when Monegy was topically administrated onto a C57BL6 mouse, it penetrated very well. The fluorescence intensity was increased upto 205 and 113 folds compared to normal and control group, respectively. Also, area of fluorescence was increased to upto 255 to 127 folds compared to normal and control group. Broad scale area of fluorescence in dermis region was observed in the Monegy-treated mice. Furthermore, Monegy induced upto 75% hair repair against depilation. It might be promoted via the induction of growth factors in hair follicle.

The purpose of this study is to analyze the 'identity' found in constructional characteristics of Geumgok Hongneung, the first imperial tomb of Korean empire. In terms of "sameness", which states for internal self-cognition among ambivalent situations while consisting identity, Hongneung inherited the prosperity of the Chosun dynasty, possessed 'sustainability' related to Cheongryangri Hongneung of Empress Myeongseong, as well as revealed various 'identitification' of situations in order to expose self-esteem as emperor and imperial nations. On the other hand, in terms of "individuality" as an external self-cognition, the opposite phase of sameness, Hongneung is a mixture of the will of Emperor Gojong and Japanese intervention hence formed 5th styles of royal tombs through 'peculiarity' which distinguishes it from the original tradition. In addition, the value of Hongneung is that it actually reflects the confusing and difficult times of the old ages, and it also involves 'excellence' as the place of the according a state funeral of Emperor Gojong and provoking March First Independence Movement. Thus, Geumgok Hongneung is a recorded landscape that clearly reflects the times of royal tombs of the Chosun dynasty, the world cultural heritage, and also the historic landscape showing extraordinary landscape of unique characteristics, 'Hwangjereung'.
Objectives: Water-soluble carthami flos (WCF) is a new mixture of Carthami flos (CF) pharmacopuncture. We conducted a 4-week toxicity test of repeated intramuscular injections of WCF in Sprague-Dawley rats. Methods: Forty male and 40 female rats were divided into 4 groups of 10 male and 10 female SD rats: The control group received 0.5 mL/animal/day of normal saline whereas the three experimental groups received WCF at doses of 0.125, 0.25, and 0.5 mL/animal/day, respectively. For 4 weeks, the solutions were injected into the femoral muscle of the rats alternating from side to side. Clinical signs, body weights, and food consumption were observed; opthalmological examinations and urinalyses were performed. On day 29, blood samples were taken for hematological and clinical chemistry analyses. Then, necropsy was conducted in all animals to observe weights and external and histopathological changes in the bodily organs. All data were tested using a statistical analysis system (SAS). Results: No deaths were observed. Temporary irregular respiration was observed in male rats of the experimental group for the first 10 days. Body weights, food consumptions, opthalmological examinations, urinalyses, clinical chemistry analyses, organ weights and necropsy produced no findings with toxicological meaning. In the hematological analysis, delay of prothrombin time (PT) was observed in male rats of the 0.25- and the 0.5-mL/animal/day groups. In the histopathological test, a dose-dependent inflammatory cell infiltration into the fascia and panniculitis in perimuscular tissues was observed in all animals of the experimental groups. However, those symptoms were limited to local injection points. No toxicological meanings, except localized changes, were noted. Conclusion: WCF solution has no significant toxicological meaning, but does produce localized symptoms. No observed adverse effect level (NOAEL) of WCF in male and female rats is expected for doses over 0.5 mL/animal/day.
This paper examines the presence of network structures among convergence technologies focusing on national R&D projects performed by GRIs(Government-sponsored Research Institutes) in Korea. The dataset of convergence technology projects, which were conducted by 24 GRIs over 3 years (2011-2013), are analysed using the network analysis method. In this paper, a convergence technology project is defined as a project that consists of 2 or more then 2 technologies according to the intermediate classification of National Standard Classification of S&T. The research results confirm that convergence researches of government-sponsored research institutes are performed more actively than the entire convergence researches of national R&D projects. Furthermore, technological fields of GRIs' convergence projects are found to be much more varied. This paper also shows that in-house researches are more active than collaborative ones with external organizations. According to the network centrality analysis, it is identified that the network central characteristics of convergence technologies can be classified into internally oriented technologies and externally oriented technologies. Convergence technologies do not just mean simple mixture of different technologies. Therefore Korean government-sponsored research institutes should make more efforts to create convergence research areas which could generate new technologies and industries more effectively than simple multidisciplinary technology researches. From this perspective, some policy suggestions can be derived on the role of government-sponsored research institutes for activating convergence researches through the analysis of status of convergence researches and networks of institutions.
The following summarized argument is the comparative research of the characteristics of automatic techniques demonstrated in the mixed expression of foreign language and Korean language in Lee Sang's poetry. Our research examines the use of foreign languages such as French and English shown in Lee Sang's poems, and then, recognized the characteristics of the automatic techniques demonstrated by the parallel marks and signs of Korean language. The automatical technique's element that Lee Sang made use of is a language of loanblend, consisting of free use of French, English, Japanese and Korean. The mathematical and geometric figures such as numbers and shapes can be seen as an important poetic language. In Lee Sang's poetry, the French words "AMOUREUSES" and "ESQUISSE" and English words "I WED A TOY BRIDE" are considered as parts of Korean language. The use of foreign language is seen by the readers as encodes of a unacquainted language and it provides rhetorical characteritstics that gives off profanatory feeling about the poetry. The poet is seen to have created a new poetic language that excess the standards of the limitations that Korean and Chinese marks have through the application of polysems and poliphonyic effects that foreign languages have. The mathematical and geometric signs are Lee Sang's special experimental elements that can't be seen in other literary poetries. They are conversational and the requirements for the expression of abstract artistry and esthetics. The language used in his poetry are external to those traditional poetic languages and they mix freely with other poetic elements to become an automatic technique used in the writing. Lee Sang's techniques can be considered as the pursuit of defiance and departure, freedom about literature and artistry. Moreover, the avant-garde expressionism is the literary form that demonstrated the sense of inferiority, nervousness and loneliness risen from physical pain and the abnormal relationship with women in the poet's personal life. The technique shows the longingness of the the Western culture and literature that lay dormant in the poet's consciousness and it is also the expression of ingenious that created the new guide in the Korean poetic literature, exceeding the European surrealism. Lastly, the automatic technique images that are demonstrated by the mixture of the foreign languages and Korean language are the creations of an innate poetic language and poetic literature that can't be imitated by anyone in Korean literature.

Several studies investigating the prevention and treatment of external parasites in farmed olive flounder Paralichthys olivaceus have found that the anticoccidial agent toltrazuril sulfone is an effective antiparasitic. Prior to undertaking a full-scale study, we developed analytical methods to detect the levels of toltrazuril and toltrazuril sulfone in farmed flounder samples using liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS/MS). This analysis showed that LC-MS/MS changed the mobile phase and collision energy of toltrazuril and toltrazuril sulfone. This was validated using established conditions. Sample pre-treatment for this process involved extraction with dichloromethane and purification by liquid-liquid extraction in formic acid, acetonitrile, and h-hexane, followed by determination of all compounds by LC-MS/MS. Separation was achieved within 10 min by gradient elution using a Capcell Pak C18 ($3.0{\mu}m$, $100{\times}2.0mm$) analytical column (Shiseido UG 120V) with a mixture of 0.1% (v/v) formic acid and acetonitrile. Multiple reaction monitoring was used for selective detection of toltrazuril and toltrazuril sulfone. This method yields satisfactory results for linearity, precision, and limits of quantification. Therefore, the method established in our study will serve as a basis for further research on parasite control by toltrazuril and toltrazuril sulfone.
Performance of a portable GC that can be utilized for the real time determination of volatile organic compounds in air was evaluated. It employs purified/compressed ambient air as the carrier gas eliminating the need for high pressure gas tanks. The compact system with dimensions of 35 × 26 × 15 ㎤ and weight of 5 kg is powered by either a 24 V DC external adapter or battery pack. Chromatograms of the mixture sample including benzene, toluene, ethylbenzene, and oxylene at concentrations of 1 ppmv and 20 ppmv represent a good reproducibility: 3.79% and 0.48% relative standard deviations (RSDs) for peak area variations; 0.40% and 0.08% RSDs for retention times. The method detection limit was 0.09 ppmv. A 30 m long, 0.28 mm I.D. column operated at an optimal condition yielded a peak capacity of 61 with good resolution for a 10 min isothermal analysis. The relative standard deviations (RSD) of the peak area variations and retention times during consecutive measurements over 27 h were less than 2.4%RSD and 0.5%RSD, respectively. Thus, this instrument makes it suitable for continuous and field analysis of low-concentration VOC mixtures in the indoor/outdoor environment as well as the spillage accident of hazardous chemicals.
Gojong' Birth Anniversary Memorial Banquet in the 1910s was forced to be performed differently from the performance style in Joseon Dynasty period that featured a harmonious majestic beauty of etiquette music. The banquet was separated into three different sessions of ceremony, luncheon and performance', which clearly revealed a distinctive pattern of etiquette music. The performance was accompanied by the dinner party or was lightly implemented as part of evening entertainment. With the use of the term entertainment, the performances belonging to this category fell into nothing but something to enjoy, amusement, fun and play. The contents of such performances were not closely woven into the fabric of the entire banquet but were individualized and scattered in a way of putting the performances in a state of flux in line with the circumstances. Therefore, it became increasingly hard to expect a high degree of completion and solid structure of performances. The items of performance included western music, popular vocal music, popular instrumental music, magic, and film, which were not played in traditional court banquet in the presence of Gojong rather than traditional music and dance performed in court. In other words, the court performance could not maintain its traditional heritage but was transformed into a mixture of popular performance and new forms of art. It was driven by the Japanese imperialism toward the atmosphere of entertainment in oblivion of tradition but not toward the external extension of court performances.

The purpose of this study is to create a self-portrait that provides an immersive experience that immerses the viewer into the problem of self-awareness. We propose a method to implement an interactive self-portrait by using audio and image information obtained from viewers. The viewer's voice information is converted into text and visualized. In this case, the viewer's face image is used as pixel information composing the text. Text is the result of a mixture of one's own emotions, imaginations, and intentions based on personal experiences and memories. People have different interpretations of certain texts in different ways.The proposed digital self-portrait not only reproduces the viewer's self-consciousness in the inner aspect by utilizing the intertextuality of the text, but also expands the meanings inherent in the text. Intertextuality in a broad sense refers to the totality of all knowledge that occurs between text and text, and between subject and subject. Therefore, the self-portrait expressed in text expands and derives various relationships between the viewer and the text, the viewer and the viewer, and the text and the text. In addition, this study shows that the proposed self-portrait can confirm the formativeness of text and re-create spatial and temporality in the external aspect. This dynamic self-portrait reflects the interests of viewers in real time, and has the characteristic of being updated and created.
