This study was conducted to determine the concentrations of particulate matter (PM) and NH3 emissions from different types of laying hens poultry houses during spring. The concentrations of PM and NH3 were measured three times (2-week intervals; March to May) in Floor-pen-, Aviary-, and Cage-type poultry houses. Overall, PM₁₀ and PM_2.5 concentrations were found to be low from 22:00 to 04:00. The PM₁₀ and PM_2.5 concentrations in Floor-pen and Cage houses were similar with no significant daily deviation. NH₃ concentrations measured over 24 h at the center and end of Floor-pen house were relatively constant. Irrespective of measurement location, NH₃ concentrations were the lowest in Floor-pen house. Moreover, NH₃ concentrations were higher at the end of Floor-pen and Aviary houses than that at the center; however, lower concentrations of NH₃ were detected at the end of Cage house. The concentrations of PM₁₀ and PM_2.5 around the poultry houses were 57.5 and 34.0 ㎍/m³, respectively, with the daily average PM₁₀ and PM_2.5 concentrations (4,730 and 447.7 ㎍/m³, respective) being the highest in Aviary house. The concentrations of NH₃ at the center and end of Cage house were the highest at 12.0 and 9.31 ppm, respectively. Furthermore, in Cage house, the emission factor of NH₃ was the lowest, whereas there was no significant difference on that of NH₃. In conclusion, among the three types of poultry houses assessed, PM (PM₁₀, PM_2.5) concentrations were higher in Aviary house, whereas NH3 concentrations were higher in Cage house.

Euonymus porphyreus, a species of plant in the Celastraceae family, is widely distributed in East Asia, especially in Southern China. The botanical characteristics of E. porphyreus have been reported, but its antioxidative and anticancer activities remain unclear. In this study, we evaluated the antioxidative and anticancer effects of ethanol extracts of E. porphyreus (EEEP) and the molecular mechanism of its anticancer activity in human lung adenocarcinoma A549 cells. The total polyphenol and flavonoid compound contents from EEEP were 115.42 mg/g and 23.07 mg/g, respectively. EEEP showed significant antioxidative effects with a concentration at 50% of the inhibition (IC50) value of 11.09 ㎍/ml, as measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. EEEP showed cytotoxic activity by increasing the SubG1 cell population of A549 cells in a dose-dependent manner. Apoptosis in A549 cells treated with EEEP was evident due to increased apoptotic cells and apoptotic bodies, as detected by Annexin V and 4,6-diamidino-2-phenylindole (DAPI) staining, respectively. EEEP-induced apoptosis resulted in increased expression of the First apoptosis signal (Fas), p53, and Bax, with decreased expression of Bcl-2 and subsequent activation of caspase-8, -9, and caspase-3, leading to cleavage of poly (ADP-ribose) polymerase (PARP). Collectively, these results suggest that EEEP may exert an anticancer effect by inducing apoptosis in A549 cells through both intrinsic and extrinsic pathways.

Objectives : The aim of this study was to develop and to verify the Korean version of the Eating Disorder Diagnosis Scale DSM-5 (K-EDDS) as a web-based diagnostic system, which enables rapid diagnosis of patients for early intervention. Methods : A total of 119 persons participated in the study, including patients with eating disorders (n=38) and college students (n=81). Along with the paper-and-pencil SCOFF, all participants completed the web-based K-EDDS, the Eating Disorder Examination-Questionaire (EDE-Q), and the Clinical Impairment Assessment Questionnaire (CIA). The semi-structured interview using the Eating Disorder Examination Interview (EDE) was conducted for participants with two or more SCOFF scores. Within two weeks, the web-based K-EDDS, the EDE-Q, and the CIA were re-tested. Results : In the exploratory factor analysis, four factors were extracted : body dissatisfaction, binge behaviors, binge frequency and compensatory behaviors. The four subscales of the web-based K-EDDS had significant correlation with each of the four subscales of the EDE-Q. The internal consistency of the web-based K-EDDS was highly satisfactory (Cronbach's alpha=0.93). The diagnostic agreement between the web-based K-EDDS and the EDE was excellent (96.83%), and the web-based K-EDDS's test-retest diagnostic agreement was fairly good (92.86%). The web-based K-EDDS and the CIA also showed significant differences between patients and general population, supporting discriminant validity. Conclusions : This study suggested that the web-based K-EDDS is a valid tool for assisting diagnosis of eating disorders based on DSM-5 in clinical and research fields.

Palladium present in colloidal-type plated spent catalyst solution that is used in electroless plating process has not been recovered but discharged as wastewater so far. Recyclig of paladium in colloidal-type plated spent catalyst solution is achieved with this study. This study presents the estimation of resource consumption and GHG emissions during the recycling and disposal of palladium in the plated spent catalyst solution using life cycle assessment. The reduction of resources and GHG are also estimated. Based on the palladium amount of 1 kg during disposal, the GHG emission amount was estimated to be 9.67E+03 kgCO₂eq., and the amount of resource consumption was 3.94E+01 kgSb-eq. However, GHG emission was 1.96E+03 kgCO₂eq., and the amount of resource consumption was 1.54E+01 kgSb-eq. during recycling. Considering the major substances affecting GHG emissions and amount of resource consumption, CO₂ was found to significantly affect GHG emissions, accounting for 91.42% in disposal and 98.37% in recycling. The major substance affecting the amount of resource consumption was hard coal, which accounted for 40.63% in disposal and 60.73% in recycling. Upon recycling 1 kg palladium, 8,967.17 kgCO₂eq. of greenhouse gas emission was reduced, while the resource consumption was reduced to 10.10 kg Sb-eq. In addition, the direct palladium resource reduction rate due to palladium recycling was 50%.

The purpose of this study is to present raw data to systematically and rationally manage the protected trees located in Changwon-si, Korea. This study investigated about the present condition and the information of location, individual, management, health and soil. The results are as follows. The protected trees were located in 26 spots, and species of trees were 9 taxa; Zelkova serrata, Celtis sinensis, Aphananthe aspera, Ginkgo biloba, Carpinus tschonoskii, Pinus densiflora for. multicaulis, Quercus variabilis, Pinus densiflora and Salix glandulosa. In protected tree types, shade trees were the most, and the majority of theirs were 200 years or more in age. The range of altitude was 14~173m, and the number of trees located in flat fields was the most. For location types, village and field and mountain were presented in the order and, in land use, land for building was the most. The range of height was 8.0~30.0m, 0.6~5.1m in crown height, 240~700cm in diameter of breast and 210~800cm in diameter of root. In case of crown area, Zelkova serrata of No.5 was most large. The status boards were mostly installed except No.23 and No.26. The sites with fence were 9 spots, and the site with stonework were 14 spots. The sites with the support beam were 5 spots, and most sites were not covered up with soil. The materials of bottom were soil, gravel and vegetation in the order. The range of withering branch rate was 0~40%, and peeled bark rate was 0~60%. The sites made holes were 23 spots, and the hole size of Aphananthe aspera of No.12 was the largest. The sites disturbed by human trampling were 7 spots, the sites by disease and insects of 2 spots, the sites by injury of 23 spots and the sites by exposed roots of 13 spots. In the results of soil analysis, there showed that acidity was pH 4.5~8.0, organic matter content of 3.5~69.8g/kg, electrical conductivity(EC) of 0.11~2.87dS/m, available $P_2O_5$ of 3.0~490.6mg/kg, exchangeable K of 0.10~1.05cmol+/kg, exchangeable Ca of 1.41~16.45cmol+/kg, exchangeable Mg of 0.37~1.96cmol+/kg, exchangeable Na of 0.25~2.41cmol+/kg and cation exchange capacity(C.E.C) of 8.35~26.55cmol+/kg.

This study was conducted through the typological analysis of theatrical activities and playscript of Packaging Troupe, which was a wandering theater troupe. It seems the activities of the packaging troupe were very active about in the 1950s. They approached to the public with various repertoires and gained popularity during the process. The playscript used in their plays can be divided into several types such as Yi dynasty drama, historical drama and modern drama and their titles are almost same as or similar to those used in Changgeuk troupe (classical opera), Female Gukgeuk troupe (Female classical opera), or Female Nongak troupe (Female farm musical band). Also, as themes, subject matters, and characters were partially same, the characteristics of previous theatrical activities could be reviewed through the playscript of packaging troupe. Also, the characteristics of the playscript of packaging troupe can be found in the list of gramophone record. The changes in popular culture can be examined in the flow of plays with various forms such as theater, film, and gramophone through the comparison between the characteristics of playscript types of packaging troupe around in the 1950s and the list of gramophone record. A typological analysis of playscript of packaging troupe confirmed the activities of packaging troupe lasted around in the 1950s. Also it can be inferred from Hyeopryulsa, Changgeuk troupe, Female Gukgeuk troupe, or Female Nongak troupe, which used traditional subject matters as repertoire of performance. Those were possible because repertoires were composed and contents changed according to the needs of the public. The changes can be also confirmed through the list inserted in the gramophone record. The association can be inferred through the same title as that of the playscript of packaging troupe and similarity of performance curtains and subject matters. As such, the interest and flow of popular culture can be examined through the types of playscript of theatrical activities of packaging troupe.

This research focuses on 'dramaturgical' performance among all the acts of a director who constructs an artistic structure. This is, specifically, the dramaturgical acts that a director comes to perform in the process of dramatizing a novel. This paper aims to suggest a new kind of approach for productive interaction between drama theory and practice, not only by documenting the process of creation but also by moulding theoretical basis on acts of a director. As you all know, creative acts in practice so far have rarely been considered as subject and purpose of academic study. Even some lucky plays and directors had to settle for fragmentary review. That's mainly because Korean theatrical circles confine the way of recording the whole process of drama in practice only to a piecemeal review of performance. As a result, there have been very few cases of observing comtemporary plays under the historical background of drama. In this regard, this paper desires to raise a question, 'is productive interaction between drama theory and creative practice possible?' and to find the answer. If what is described in this paper can have worth beyond a mere record of creative acts, it may establish theoretical grounds on interpreting the play stage of this era by reading, in the contexts of drama history, a director's dramaturgical performing acts to dramatize a novel. The researcher of this paper, as a director of a theater troupe like a human and artistic community, adapted "Crime and Punishment" by Dostoevsky into four plays. They are , , , , and completed in 2009, 2011, 2012, and 2014, respectively as an independent theatric work having no connections to each other in story. Not only because the four plays share the same novel as its origin but also because an identical system is applied to dramatization of the novel, it gives an opportunity to focus on and perceive the role of the director. During the process of dramatiztion, the director, the researcher of this paper, carried all the duties, such as selecting a text, approaching the text theoretically and academically, adapting it for drama, picking out appropriate episodes. This paper defines all these acts as dramaturgical performing acts. In this sense, this paper can also be seen as a documentary of 'acts' performed during the process of dramatization.

Marriage forms a minimal social unit. Marriage can affect not only relative relationship but also possession of property. Regarding legal issues related to marriage, mainly the civil law, especially the family law section, regulates. However, marriage has also a significant legal effect in terms of taxation. This article deals with the taxation of gift tax among them. In Korea, if you give more than 600 million won in assets to your husband and wife, the donee must pay the gift tax. However, there has been little research into the influence of the marital property system on the taxation of gift tax on the donation between married couples. There are two legislative approaches to the attribution of property held by married couples. The one is separate property system, the other is community property system. Under separate property system, husband and wife own property separately. The community property system recognizes marital property of married couple as a common property of married couple. The legal property system in Korea is separate property system. However, married couples can adopt the community property system as a marital property system by their agreement. Currently, most Korean couples are subject to separate property system as a marital property system. There is no legal problem to levy the gift tax on the donation between couples who are subject to separate property system. The problem is the donation of asset between couples who are subject to the community property system. In community property system, most property acquired during marriage (except for gifts or inheritances) is considered community property. community property means property owned jointly by both partners. Some argue that the gift tax can not be taxed between married couples who are subject to the community property system. In this paper, we examine whether these arguments are valid.

In the former half of the 18th century, For this period the literary people who led the literature of Nam'in were Sadaebu named the so-called Munoepa. There were Gang Pak(姜樸), Lee In-bok(李仁復), Lee Jung-hwan, Oh Gwang-un(吳光運), and Gang Pil-shin(姜必愼) in Munoepa(門外派). All these people as Sadaebu of Nam'in kept company with families of each other, had close relations from early childhood, and shared with same opinions in various ways like politics, culture, etc. They had intimate relationships not only in politics but also in literature, and primarily acted their part regarding the development of literary circles in the first half of the 18th century. Many individual poets who achieved the outstanding literary accomplishment appeared in the late period of Joseon Dynasty, especially in the eighteenth and nineteenth centuries. They actively made progress in their literary works with Sisa. The poets in similar positions had the Sisa to show their literary ability and check on their view about the literature. They briskly tried to express their own literary intention in activities of Sisa. Gang Pil-shin is a literary representative of the late period of Joseon Dynasty Nam'in. Through the exchange relationship of Gang Pil-shin, we can confirm certain aspects of his literary world. People who have tied up with Gang Pil-shin are largely divided into three. First, it is a literary person in Geungi Nam'in literati, typified by Backryeonsidan, Jinju Gang family, Gyeongsang Provinces area that was a place of residence. The exchanges of Gang Pil-shin were done via a poetry club. a poetry club was basically conducted mainly on relatives such as Gang Pak. However, the members of a poetry club changed according to the area where you live. Gang Pil-shin made a poetry club while coming back and forth between Seoul and Gyeongsang Provinces. This means that Gang Pil-shin also had special attention as Geungi Nam'in (近畿 南人), but also had a positive nature as Yeongnam south person. A closer look at what linguistics of Gang Pil-shin Geungi Nam'in and Yeongnam Nam'in had special characteristics late period of Joseon Dynasty It is possible to confirm the special characteristics of Seoul and the local literary exchange. For this reason, it seems that more detailed examination of the literature of Gang Pil-shin is necessary.

In this article, how the Bangmok(榜目) documents, which are essentially lists of successful passers for the civil competitive examination system of the $Chos{\breve{o}}n$ dynasty, when rendered into digitalized formats, could serve as source of information, which would not only lets us know the $Chos{\breve{o}}n$ individuals' social backgrounds and bloodlines but also enables us to understand the intricate nature that the Yangban network had, will be discussed. In digitalized humanity studies, the Bangmok materials, literally a list of leading elites of the $Chos{\breve{o}}n$ period, constitute a very interesting and important source of information. Based upon these materials, we can see how the society -as well as the Yangban community- was like. Currently, all data inside these Bangmok lists are rendered in XML(eXtensible Makrup Language) format and are being served through DBMS(Database Management System), so anyone who would want to examine the statistics could freely do so. Also, by connecting the data in these Bangmok materials with data from genealogy records, we could identify an individual's marital relationship, home town, and political affiliation, and therefore create a complex narrative that would be effective in describing that individual's life in particular. This is a graphic database, which shows-when Bangmok data is punched in-successful passers as individual nodes, and displays blood and marital relations in a very visible way. Clicking upon the nodes would provide you with access to all kinds of relationships formed among more than 90 thousand successful passers, and even the overall marital network, once the genealogical data is input. In Korea, since 2005 and through now, the task of digitalizing data from the Civil exam Bangmok(Mun-gwa Bangmok), Military exam Bangmok (Mu-gwa Bangmok), the "Sa-ma" Bangmok and "Jab-gwa" Bangmok materials, has been completed. They can be accessed through a website(http://people.aks.ac.kr/index.aks) which has information on numerous famous past Korean individuals. With this kind of source of information, we are now able to extract professional Jung-in figures from these lists. However, meaningful and practical studies using this data are yet to be announced. This article would like to remind everyone that this information should be used as a window through which we could see not only the lives of individuals, but also the society.
