Heute ist das Problem in der globalen Gesellschaft, mit dem wir uns $besch{\ddot{a}}ftigen$ sollen, die ${\ddot{o}}kologische$ Krise. Einer der Wege, um die ${\ddot{o}}kologische$ Krise zu $l{\ddot{o}}sen$, ist das Finden des ${\ddot{o}}kologischen$ Gleichgewichts des Landes und des menschlichen $K{\ddot{o}}rpers$. Dieser Aufsatz behandelt mit dem Begriff von "Salim (Haushalten und Beleben)" die Beziehung des Menschen zum Land, und die Beziehung des Landes zum menschlichen $K{\ddot{o}}rper$. In $Ankn{\ddot{u}}pfung$ an das Konzept der ${\ddot{o}}kologischen$ "Salim" laufen bei diesem Aufsatz $vielf{\ddot{a}}ltige$ Argumente wie die Beziehung des Menschen zum Land als ${\acute{e}}coum{\acute{e}}n$ Ethik, "Salim des Landes" und "Salim des $K{\ddot{o}}rpers$" zusammen. Das ${\ddot{o}}kologische$ Ungleichgewicht im 21. Jahrhundert weist darauf hin, dass die menschliche Beziehung zum Land als einem Platz der menschlichen Besiedlung bis jetzt nicht gesund war. Das Anfordern der ${\acute{e}}coum{\acute{e}}n$ Ethik von heute erweist sich, dass wir herausarbeiten $m{\ddot{u}}ssen$, die gesundliche Beziehung des Menschen zum Land wieder zu beleben. Im Kapitel 3, in $Anschlu{\ss}$ an das Konzept der ${\ddot{o}}kologischen$ "Salim" des Landes, ist die Tatsache in Betracht zu ziehen, dass das Land nicht einfach wirtschaftlichen Wert hat, sondern zur Gemeinschaft des kosmischen Lebens $geh{\ddot{o}}rt$. Mit dem Konzept der ${\ddot{o}}kologischen$ $K{\ddot{o}}rper$-Salim, versucht das Kapitel 4 darzulegen, wie der menschliche $K{\ddot{o}}rper$ im kosmischen Lebenszyklus beteiligt ist. Heute, konfrontiert mit der Amnesie vom Leben des Landes und mit dem $Sch{\ddot{a}}den$ des $K{\ddot{o}}rper-{\ddot{o}}kosystems$, sollten wir unser Bewusstsein und unsere Lebensweise $ver{\ddot{a}}ndern$ und die ${\ddot{o}}kologischen$ Salim-Bewegung in die Praxis setzen.

In Manpasikchok(die Welle $bes{\ddot{a}}nftigende$ und Friede stiftende $Zauberfl{\ddot{o}}te$) trift der Protagonist Chongsu im Traum seinen Vater, den er nach der Trennung $w{\ddot{a}}hrend$ des Koreakrieges nicht wiedergesehen hat. Sein Vater besucht das Grab seiner Mutter, die nach der Trennung 56 Jahre lang allein gelebt hatte. Die Vaterfigur in Manpasikchok, die Oh Taesok gestaltet hat, ist die Vater-Imago des Autors. Sein Vater ist $w{\ddot{a}}hrend$ des Krieges von den nordkoreanischen Soldaten nach Nordkorea geschleppt worden und kam nicht $zur{\ddot{u}}ck$. Manpasikchok ist ein Versuch, seinen Wunsch, mit seinem Vater, den er durch die Teilung Koreas nicht wieder sehen konnte, wiederzutreffen und endlich Friede zu $schlie{\ss}en$, auf der $B{\ddot{u}}hne$ zu verwirklichen. Die Vater-Imago in Manpasikchok bleibt aber nicht auf der bibliographischen Ebene, sondern erweitert sich zu einem Archetyp der nationalen Mythologie, indem sie mit dem Mythos Manpasikchok zusammengebunden wird. Dadurch wird das $St{\ddot{u}}ck$ zu einem Diskurs um die koreanische Wiedervereinigung erweitert. Oh ${\ddot{u}}berlegt$ sich in seinem $St{\ddot{u}}ck$ ${\ddot{u}}ber$ die $M{\ddot{o}}glichkeit$ des Zusammentreffens und der $Vers{\ddot{o}}hnung$ zwischen den $S{\ddot{u}}dund$ Nordkoreanern, die seit ${\ddot{u}}ber$ 50 Jahre lang in ganz anderem System gelebt haben. Das wird durch die Szene des Treffens des Protagonisten mit seinem Vater auf der $B{\ddot{u}}hne$ exemplarisch vorgezeigt. In Manpasikchok wird die Grundlage zur inneren Vereinigung vorbereitet. $Zun{\ddot{a}}chst$ wird aus der Sicht der Nordkoreaner die $s{\ddot{u}}dkoreanische$ Gesellschaft, die an Habgier verhaftet ist, kritisiert. Als Alternative dazu wird das Gewissen, das die Habgier korrigieren wird, vorgeschlagen. Durch die Dialoge der Nordkoreaner wird die Wichtigkeit der Kommunikation betont, die erst dann verwirklicht werden kann, wenn sich die $S{\ddot{u}}d$- und Nordkoreaner mit gegenseitigem Vertrauen treffen. Manpasikchok bietet eine $M{\ddot{o}}glichkeit$ der kulturellen Vereinigung, indem sich die Leute aus beiden Teilen Koreas trotz des Dialekts gut kommunizieren. $Dar{\ddot{u}}ber$ hinaus bindet Oh Taesok das Volksspiel aus Nordkorea Bukchong $L{\ddot{o}}wenspiel$ mit dem $s{\ddot{u}}dkoreanischen$ Puppenspiel zusammen und veranschaulicht die Vereinigung als eine Perfomance auf der $B{\ddot{u}}hne$.

Due to the globalization of Korean foods, there are great interests in traditional Korean foods. Thus, the enhancement and development of makgeolli processing have been constantly accomplished. In case of makgeolli, the storage stability is very important because the fermentation of makgeolli during distribution is still progressed. Therefore, the objective of this study was to investigate storage stability of makgeolli by separation storage methods. During the 30-day storage at $10^{\circ}C$, pH value, titratable acidity, color value, sugar content, reducing sugar content, and alcohol content were measured. Microbial cell counts were also evaluated. Reducing sugar content was decreased after 10 days for all the samples. In the case of titratable acidity and color, these values were constantly increased with storage time. Especially, the yellowness value of the precipitate of makgeolli was increased by two times than that of the beginning. There was a decreasing tendency for lactic acid bacteria with storage time. In case of yeast, there was a decreasing tendency after 15 days, but the significance was not detected. The quality changes in the samples from centrifugal separation were relatively less than the control. Therefore, the separation storage method could affect the enhancement of makgeolli quality during distribution.

In diesem Aufsatz wird die Geschichte der Bewertungsdiskussion in Deutschland vorgestellt. Bis zum 18. Jh. war das Ziel der Archivarbeit die Systematisierung der rechtlichen und politischen Kenntnissen. Der juristisch geschulte Archivar hob Unterlagen in der Regel aus $Gr{\ddot{u}}nden$ der Rechtssicherheit auf. Vernichtet wurde, was schon seit $l{\ddot{a}}ngerem$ im Archiv lag. Nach dem Zusammenfall des alten Regimes haben die Archivare keine mehr mit dem Recht des Herrschers zu tun. Und die Archive wurden zu $Lagerst{\ddot{a}}tten$ der Geschichte und Forschung. $F{\ddot{u}}r$ den Ordnung der Archivgut, die aus den verschiedener Dienststellen stammten, wurde das Provenienzprinzip gebildet. Die Archivare richtete sich auf das inhaltsorientierten Bewertungsverfahren, das die wissenschaftlichen $Bed{\ddot{u}}rfnisse$ befriedigte. Der Anlass der Bildung der modernen Archivtheorie war der ersten Weltkrieg. Das Problem, wie man die Massenakten, die $W{\ddot{a}}hrend$ dieses Krieges entstanden, behandeln sollten, $f{\ddot{u}}hrte$ unter dem $Einflu{\ss}$ der Demokratie zur Bildung der Provenienz-orientierte Bewertungsdiskussion. Aufbau, Zielsetzung und Verfahren der aktenbildenden Stelle bildeten den Ausgang der Bewertung. Im Klima ${\ddot{o}}ffentlicher$ $B{\ddot{u}}rokratieablehnung$ der 50er und 60er Jahren wurde die inhaltsorientierte Auswahl wieder die vorherrschende Methodenvorgabe. Diese Theorie, die Booms vertritt, $f{\ddot{u}}hrt$ zu der Theorie der dokumentation strategy von Ende 20. Jh.

As an opportunistic bacterial pathogen, Pseudomonas aeruginosa PAO1 contains two phenazine-producing gene operons, phzA1B1C1D1E1F1G1 (phz1) and phzA2B2C2D2E2F2G2 (phz2), each of which is independently capable of encoding all enzymes for biosynthesizing phenazines, including phenazine-1-carboxylic acid and its derivatives. Other previous study reported that the RpoS-deficient mutant SS24 overproduced pyocyanin, a derivative of phenazine-1-carboxylic acid. However, it is not known how RpoS mediates the expression of two phz operons and regulates pyocyanin biosynthesis in detail. In this study, with deletion of the rpoS gene in the $PA{\Delta}phz1$ mutant and the $PA{\Delta}phz2$ mutant respectively, we demonstrated that RpoS exerted opposite regulatory roles on the expression of the phz1and phz2 operons. We also confirmed that the phz1 operon played a critical role and especially biosynthesized much more phenazines than the phz2 operon when the rpoS gene was knocked out in P. aeruginosa. By constructing the translational reporter fusion vector lasR'-'lacZ and the chromosomal fusion mutant $PA{\Delta}lasR::lacZ$, we verified that RpoS deficiency caused increased expression of lasR, a transcription regulator gene in a first quorum sensing system (las) that activates overexpression of the phz1 operon, suggesting that in the absence of RpoS, LasR might act as an intermediate in overproduction of phenazine biosynthesis mediated by the phz1 operon in P. aeruginosa.

Water quality is characterized by various complex factors. Therefore, a systematic understanding of water quality trends is required to carry out a proper evaluation. In this study, we analyzed the spatio-temporal water quality characteristics of the Nakdong River using five-year data from 2012 to 2016. Data was collected on the pH, DO, BOD, COD, SS, TN, TP, TOC, WT, EC, $NH_3-N$, $NO_3-N$, $PO_4-P$, Chl-a, rainfall, and total and fecal coliforms. A total of 38 water quality measurement stations, from Andong1 to Gupo, were considered. Statistical analyses including trend, cluster, and factor analyses were conducted to identify the dominant water quality components affecting the Nakdong River. The Nakdong River was spatially classified into three groups for up-stream (Andong1 to Sangju1), mid/up-stream (Donam to Dalseong), and mid/down-stream (Hwawonnaru to Gupo) data collection, and temporally into two groups for summer/fall (7~10), and the rest of the season (11~6) data. The water quality of the entire Nakdong River showed trends similar to the mid/down-stream section, which indicates the importance of water quality management in this section. Suspended solids, phosphorus, and coliform groups were established as important factors to be considered in the summer/fall season across the river, especially in the mid/down-stream section. Nitrogen and organic matter were identified as important factors to be considered in the rest of the season, especially in the mid/up-stream section. This study could help determine the water quality components that should be intensively monitored in the Nakdong River.

The purpose of this study was to investigate treatment characteristics of diatomite filtration, that would allow water recovery from biologically-treated effluent for reuse. Diatomite, Celpure 100, and acid clay were used as filter-aids, with a support filter manufactured from polyethylene (PE), and polypropylene (PP). This pre-coating process using diatomite filter-aids, is used in the filtration range of pressure filters, and has consistently provided high-quality separation. The results showed that variations in average removal efficiency of SS, and T-P from biologically treated effluent by the diatomite-coated PE filter, were approximately 82.2 ~ 88.9 % and 4.8 ~ 21.1 %, respectively. T-P treatment efficiency of the PP filter pre-coated with diatomite and $Celpure^{(R)}100$ at $57.64g/m^2$, was approximately $24{\pm}10%$ and $40{\pm}15%$ on average, respectively. Particle size distribution of secondary effluent varied from 0.05 to $200{\mu}m$, and $d_{50}$ value was $20.76{\mu}m$. The size distribution of particles in the diatomite filtrate ranged from 1.26 to $101.1{\mu}m$ when pre-coated with diatomite filter-aid, at a content of $57.64g/m^2$. Diatomite filter aids, i.e., the particles that form the pre-coating layer, capture very fine particles as well as macromolecules, owing to their complex structure with numerous fine microscopic pores, and surface properties. The filtration process using diatomite and $Celpure^{(R)}100$ as filter aids, has been successfully applied, to recover water from sewage for reuse. The disadvantage of the process, is that the particle size of the filter-aid is spent, because of pressurization.

The purpose of this study was to investigate the body's strategy through kinematic variables of the lower extremities and ground reaction forces to maintain the club-head speed and ball accuracy despite the three stances during the golf swing. Ten male golfers who official handicap two were participate in the experiment. All subjects performed swing after maintaining the address posture according to stance conditions(square; SS, open: OS, closed: CS). Using a 3D motion analysis system and force plateform, the results were calculated with the 7-iron full swing each stance. In result, there was no difference in center of displacement, and left and right hip and knee joint angle displacement. Left ankle joint was largely plantar-flexed in OS, and right ankle joint was largely performed in CS from the address to the downswing. From address to take-back, right foot had a large left direction and the left foot had a right direction were greater in OS than in CS. Therefore, despite various stances, maintaining the same posture at impact is thought to have a positive effect on club head speed and ball direction.

In this study, the histological changes of Zacco platypus exposed to discharge from a Wastewater Treatment Plant (WTP), which is a point source, for a long time (2 to 3 years) were compared to the same species at a reference site (Ref.). Overall, tissues displayed various lesions in samples obtained at the point where discharge water from the point source was mixed. In the skin tissue, mucus cells from the epithelial layer expanded to the multilayered epithelium, indicating the immune system was activated. Epithelial cell detachment and proliferation were most prominent in the gills, which may have adversely affected circulation and respiration. Our data suggest immune system collapse was due to stimulation by aquatic substances. Both the fish phase analysis and the water quality analysis demonstrated depreciated conditions at the point source as compared to the reference stream, supporting the histological health evaluation results. These data together suggest a histological approach can also be used to assess water quality, and to an even higher degree when combined with other existing methods. Given the presented evaluation, improvement in the water quality of water discharged from WTP's is required.

Suspended Solids (SS) generated in rivers are mainly introduced from non-point pollutants or appear naturally in the water body, and are an important water quality factor that may cause long-term water pollution by being deposited. However, the conventional method of measuring the concentration of suspended solids is labor-intensive, and it is difficult to obtain a vast amount of data via point measurement. Therefore, in this study, a model for measuring the concentration of suspended solids based on remote sensing in the Nakdong River was developed using Sentinel-2 data that provides high-resolution multi-spectral satellite images. The proposed model considers the spectral bands and band ratios of various wavelength bands using a machine learning model, Support Vector Regression (SVR), to overcome the limitation of the existing remote sensing-based regression equations. The optimal combination of variables was derived using the Recursive Feature Elimination (RFE) and weight coefficients for each variable of SVR. The results show that the 705nm band belonging to the red-edge wavelength band was estimated as the most important spectral band, and the proposed SVR model produced the most accurate measurement compared with the previous regression equations. By using the RFE, the SVR model developed in this study reduces the variable dependence compared to the existing regression equations based on the single spectral band or band ratio and provides more accurate prediction of spatial distribution of suspended solids concentration.
