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.

This study examined the process of admission selection of vocational high schools and meister high schools and how the process have been utilized by schools to select appropriate students and by students to make decisions for application in consideration of their interests, aptitudes, and career paths. To address the purpose of this study, Focus Group Interviews(FGI) were conducted with three groups of participants: vocational high schools and meister high schools teachers, high school freshmen' parents, and middle school teachers who had many students advanced to vocational and meister high schools. The findings indicated that during the promotion process, schools made efforts to attract students with higher GAP and provided information mainly regarding employment rate instead of curriculum or program of majors. Since schools usually visited middle schools where higher GPA students were, not all students had balanced opportunities of high school promotions and enough information about majors. For the application process, the schools placed a high value on scholastic performance while students applied high schools considering their interests, aptitudes, and career paths. In terms of admission type and criteria, the high school teachers reported no big differences between special admission and general admission while students took advantage from the special admission process which was less competitive than general admission. Based on the findings, a number of suggestions were made in order to improve the process of admission selection of vocational high schools and meister high schools.

Korea has recently invested much of its effort in fostering talents in scientific fields to establish a foundation for sustainable future growth. From this perspective, the ministry of education has come up with a special rule aimed at achieving the substantiality of engineering schools in universities. The ministry has been providing educational support by providing a tech-innovation center, industry-oriented education, and policies such as PRIME. Despite this support, most students in the natural science field end up being hired in fields not related to their majors. There has been a growing opinion regarding the need for career education for these students. In this research, based on a social cognitive career theory (SCCT) model that provides a comprehensive understanding of career development, this research would like to practically examine the relationship among college students' career preparation behaviors and influencing variables, such as grit, career decision-making self-efficacy, outcome expectation, and major interest. Data from 153 natural-science majors at A college in Korea were collected and analyzed using path analysis. The result was that the data strongly supported the model explaining the relationship between career preparation behaviors and influencing variables. Based on this result, we propose that career education that can promote grit, career decision-making self-efficacy, outcome expectation, and major interest is required to encourage students in the field of the natural sciences to pursue career preparation behaviors related to their majors.

Early marriage in contemporary society has brought about many problems. The practice is encouraged by gender inequality, poverty and social norms. It reproduces social power imbalances including increased economic vulnerability of women, low educational attainment of girls, gender inequality at home and in the labor market, physical and sexual violence against women and their health problems. The Ethiopian government increased the minimum legal age of marriage for women from 15 to 18 years, by revising its family code in 2000 and newly adopting a criminal law in 2005 that includes punishment against any harmful tradition. Nonetheless, early marriage is still widely practiced in many parts of rural Ethiopia. This is because the practice has long been embedded and deeply rooted in the lives of the people. Earlier literature on early marriage in Ethiopia tends to focus only on women's experiences and regard that all early-married people, particularly women, are unhappy with their lives. This paper attempts to explore the issue of early marriage through voices of people with diverse socioeconomic backgrounds, in order to address the limitations of the previous literature. This article aims at examining why early marriage has occurred in Ethiopia and how it has affected family life and women's educational attainment, focusing on the case of Meki town. As seen from this study, it is true that early marriage generally had negative influences on the lives of women. However, it is equally true that some men are also victims of the practice while some women have improved their lives by means of it. This implies that we need to listen to the voices of diverse people when we examine early marriage.

The historical value of the official documents of the Government General of Choson preserved as permanent archived documents has long been recognized. However, the fact that only parts of the overall documents were preserved and that the contents of the existing documents is not uniform, results in many problems regarding the evaluation and usage of such documents as archives. This study attempts to appraise a series of archival documents related to urban district planning compiled during the colonial era. Although limited in terms of its applicability to the development of an evaluation method for the official documents of the Government General of Choson as a whole, by evaluating the value of these documents based on the background of the documents produced during the Government General of Choson's implementation of its colonial policy, this study provides an important indicator of how such documents should be used in the future. On the other hand, the assessment of historical records such as the official documents of the Government General of Choson which have already been designated and preserved as permanent archived documents should not be perceived as an attempt to dispose of the relevant documents. With regard to the appraisal of historical archives, it is necessary to consider measures to link such documents with existing databases or information contents in order to heighten access to and usage of the relevant documents in the future.

Fat accumulation in adipocytes occurs through the process of adipogenesis in which preadipocytes differentiate into adipocytes. Obesity is a metabolic disorder caused by excessive accumulation of fat in the body, which increases the incidence of cardiovascular diseases, hypertension, type 2 diabetes, hyperlipidemia, and various cancers. Recently, inhibition of adipocyte differentiation was shown to be a potential antiobesity strategy. In this study, the inhibitory effect of dichloromethane fractions from Illicium verum Hooker fil. water extract on the differentiation of 3T3-L1 preadipocytes to adipocytes was investigated. Dichloromethane fractions from I. verum Hooker fil. significantly inhibited adipocyte differentiation when applied during the adipocyte differentiation process, as assessed by measuring fat accumulation using Oil-red O staining. In addition, dichloromethane fractions from I. verum Hooker fil. reduced important adipogenic transcription factors, such as CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), $C/EBP{\beta}$, and peroxisome proliferator activated receptor ${\gamma}$ ($PPAR{\gamma}$). The expression of FAS and LPL, which are terminal differentiation markers of mature adipocytes, was also reduced in the 3T3-L1 adipocytes treated with dichloromethane fractions from I. verum Hooker fil. In addition, the treatment significantly inhibited mitotic clonal expansion, which is essential for adipocyte differentiation, by arresting the G1 phase of the cell cycle. Taken together, these results suggest that dichloromethane fractions from I. verum Hooker fil. may be a natural material with antiobesity effects.

This study was initiated to solve the difficulties of aged and female workers in agriculture society due to aging and demise of young people. In the case of the conventional elevated lift, the risk of exposure to uneven road or work environment, not the difficulty of professional qualification and operation, and the risk of exposure to the uneven road or working environment, were also studied based on previous researches so that women could easily and efficiently perform productive agriculture. First, the simulation was carried out through the prediction model of traction performance using the object of agricultural forklift, and the soil of the Kimhae city in Gyeongnam (34.125kPa, internal friction angle 35.294deg, external friction angle 13.620deg, Adhesion force 5.750 kPa, average cone index 0-15 cm cl, 1001.8 kPa). In the case of the forklift for simulation, the driving force and the kinetic resistance prediction modeling of the agricultural electric forklift are modeled. Based on this model, the motor control drive adopts the 1232E model, which is a drive dedicated to AC motor, and divides the two drivers into master and slave And the model for the simulation was designed to control motor drive, hydraulic drive, and various outputs on the main PCB. The simulation model is undergoing continuous simulation, modification and supplementation. Based on this research, we will continue research for development of safer and more efficient agricultural electric forklift.

The aerial launching UAV(Unmanned Aerial Vehicle) mainly uses a set of folding tandem wings to maximize flight performance and minimize the space required for mounting in a mothership. This folding tandem wing has a unique aerodynamic problem that is different from the general type of fixed wing aircraft, such as the rear wing interference problem caused by the wing of the front wing wake and vortex, and the imbalance of the pivot moment applied to the front and rear wings when the wing is deployed. In this paper, we have modeled and simulated various cases through computational fluid dynamics based on the finite volume method and analyzed various aerodynamic phenomena of the tandem wing type aircraft. We find that the front wing shall be installed higher than the rear for minimizing the wake influence and the rear wing can be deployed faster than the front because of the pivot moment due to aerodynamic forces. Also, considering the pivot moment due to aerodynamic force, the rear wing can be deployed much faster than the front wing. Therefore, it is necessary to consider it when developing the wing deploy mechanism.

The paper presents the rotordynamic performance measurements and model predictions of a fuel cell electric vehicle (FCEV) air compressor supported on gas foil bearings (GFBs). The rotor has an impeller on one end and a thrust runner on the other end. The front (impeller side) and rear (thrust side) gas foil journal bearings (GFJBs) are located between the impeller and thrust runner to support the radial loads, and a pair of gas foil thrust bearings are located on both sides of the thrust runner to support the axial loads. The test GFJBs have a partial arc shim foil installed between the top foil and bump strip layers to enhance hydrodynamic pressure generation. During the rotordynamic performance tests, two sets of orthogonally installed eddy-current displacement sensors measure the rotor radial motions at the rotor impeller and thrust ends. A series of speed-up and coast-down tests to 100k rpm demonstrates the dominant synchronous (1X) rotor responses to imbalance masses without noticeable subsynchronous motions, which indicates a rotordynamically stable rotor-GFB system. Finite element analysis of the rotor determines the rotor free-free (bending) natural modes and frequencies well beyond the maximum rotating frequency. The predicted damped natural frequencies and damping ratios of the rotor-GFB system reveal rotordynamic stability over the speeds of interest. The imbalance response predictions show that the predicted critical speeds and rotor amplitudes strongly agree with the test measurements, thus validating the developed rotordynamic model.

The purposes of this study was to confirm the current issues of workforce policy of dental auxiliary personnel in Korea. The literature review and data collection were conducted in terms of the auxiliary personnel supply, regional distribution, legal works, working environment. Despite the rapid increase in the number of dental hygienists, the number of active dental hygienists is less than half of the total, and the dental clinics still experience the shortage. Considering the dental hygienist's work, the available dental auxiliary personnel for the dental assistance is limited. The proportion of dental hygienists is concentrated in large cities, and the ratio of dental clinics composed of only dental hygienists is high. Thus, it is essential to look for a plan to solve the disparity. The criterion for judging the legality of the works is ambiguous because a large portion of dental hygienist's work is not specified in the Medical Technicians Act. The job life is also shortened, and occupational profession and satisfaction are lowered. Thus, job burnout is accelerating. The difference between the legal works and the practiced works of dental hygienist and the conflict between the personnel might be due to the lack of utilization plans for the dental personnel at the government level. Therefore, the government should establish the roles of dental hygienist in accordance with the demands of the dental health service, institutionalize the necessary policies accordingly, and make efforts to establish plans to improve the relevant laws and utilize the manpower appropriately.
