The objectives of this study were to find out the plant to enhance immune activity among 42 kinds of foods frequently consumed by the Korean elderly consisting of 5 food groups and 5 wild plants. Each sample was assessed the immunoactive effect by measuring NFkB/ AP1 gene expression, nitric oxide and cytokine production in RAW-Blue™ cell. Soybean sprouts of 47 plants showed the highest NF-κB/AP1 gene expression at the level of 1.13 ± 0.03 (O.D. 650 nm) and Soritae, sweet potato, banana, apple, garlic, crown daisy, cabbage and Ailanthus altissima also had high activity of NF-kB/AP1 gene in RAW-Blue™ cell stimulated by LPS. NO production of Ailanthus altissima was significantly higher than that of other plants and 16 plants of glutinous sorghum, black rice, Seoritae, Heuktae, sweet potato, banana, apple, garlic, mungbean sprouts, spinach, crown daisy, young pumpkin, cabbage, soybean sprouts, Actinidia arguta and Aster scaber were the next best activity. The above results selected 17 out of 47 plant samples. Moreover, soybean sprouts was significantly shown to increase TNF-α (1,509.55 ± 1.38 pg/mL) and IL-1β (54.56 ± 1.08 pg/mL) cytokines in comparison with RAW-Blue cell stimulated by LPS. According to the results of in vitro evaluation, the ethanol extract of soybean sprout increased the production of immune-enhancing cytokines by proliferation of macrophages. In addition, NF-kB transcription factor activity and NO production ability were excellent, and it was selected as a material having excellent immunological activity.

This study examined the influence of operating parameters on the electrosorptive recovery system of lithium ions from aqueous solutions using a spinel-type lithium manganese oxide adsorbent electrode and investigated the electrosorption kinetics and isotherms. The results revealed that the electrosorption data of lithium ions from the lithium containing aqueous solution were well-fitted to the Langmuir isotherm at electrical potentials lower than –0.4 V and to the Freundlich isotherm at electrical potentials higher than –0.4 V. This result may due to the formation of a thicker electrical double layer on the surface of the electrode at higher electrical potentials. The results showed that the electrosorption reached equilibrium within 200 min under an electrical potential of –1.0 V, and the pseudo-second-order kinetic model was correlated with the experimental data. Moreover, the adsorption of lithium ions was dependent on pH and temperature, and the results indicate that higher pH values and lower temperatures are more suitable for the electrosorptive adsorption of lithium ions from aqueous solutions. Thermodynamic results showed that the calculated activation energy of 22.61 kJ mol–1 during the electrosorption of lithium ions onto the adsorbent electrode was primarily controlled by a physical adsorption process. The recovery of adsorbed lithium ions from the adsorbent electrode reached the desorption equilibrium within 200 min under reverse electrical potential of 3.5 V.

숭고는 미학과 밀접한 관계를 지닌 개념으로서, 대상에 대해 명상할 때 에 우리의 정신과 육체의 정서적 감각에 광범위한 영향을 미친다. 롱자이너스는 숭고 를 고양된 스타일을 재현하는 문학작품에서의 “숭고한 열정의 존재”로 정의하고, 에드 먼드 버크는 거리감을 두고 자연의 파괴적 위력에 연관된 숭고의 경험에서의 고통과 즐거움에 초점을 맞추어 공포와 환희의 균형을 맞춘다. 칸트는 버크의 공포와 환희의 기이한 형태를 결합하고, 라깡은 프로이트와 칸트의 문맥에서 극단과 무한을 추구하여, 칸트의 숭고를 넘어서는 승화의 개념을 구성했다. 본 논문은 라깡의 숭고와 승화의 문맥에서 예이츠의 “비극적 환희”에 재현된 숭고를 예이츠의 시에서 찾아, 예이츠의 숭고의 시학을 살펴본다.

Osteoporosis is a major worldwide public health problem that poses a great economic burden to society. Puerariae Radix, the dried root of Pueraria lobata (Wild.) Ohwi, has been widely used in Asia. This study investigated the effects of Puerariae Radix (PR) on bone loss in ovariectomized (OVX) mice. C3H/HeN mice (10 weeks old) were divided into sham and OVX groups. The OVX mice were treated with vehicle, 17β-estradiol (E2), PR (oral administration, 250 mg/ kg/day) or PR (intraperitoneal administration, 50 mg/ kg/every other day) for 6 weeks. Grip strength, uterus weight, serum alkaline phosphatase (ALP), estradiol concentration and osteoclast surface levels were measured. Tibiae were analyzed using microcomputed tomography. There were no significant differences in the degree of grip strength, body weight and uterine weight between OVX group and PR-treated group. As compared with the OVX group, the serum estradiol levels were significantly increased in the PR-treated group. PR (i.p.) significantly preserved trabecular bone volume, trabecular bone number, structure model index and bone mineral density of proximal tibiae metaphysic. The administration of PR lowered serum ALP and osteoclast surface levels in OVX mice, suggesting that PR can reduce the bone turnover rate in mice. The results indicate that the supply of PR can prevent OVX-induced bone loss in mice.

The International Organization for Standardization (ISO) published ISO 9001 Quality Management System (QMS)-Requirements in 1987 and has revised four times since then. ISO 9001:2015 is the latest edition. This latest edition has two most noticeable changes. The first major change of new edition focuses on performance with an emphasis on Risk-Based Thinking (RBT) to enhance the process approach. The new edition consists of ten clauses whose first three clauses are largely same as older edition but risks are clearly stated and stressed in last seven clauses, emphasizing on Plan-Do-Check-Act cycle at all levels in the organization. The second major change is that the new edition has the same overall structure as other ISO management system standards known as High Level Structure (HLS) with Annex SL. The companies obtained the certificate of new ISO 9001:2015 QMS by September 15, 2018 in order to maintain as an ISO QMS registered firm. In this article we collected transition audit data from more than 100 companies that registered ISO 9001:2015 QMS for recent three years. We performed a statistical analysis to disclose the relationships between the characteristics of companies and the minor nonconformities found in ISO 9001:2015 requirements during transition audit processes. We also aim to interpret the findings and deduce the implications of the statistical results.

Linear carbon chains (LCCs) encapsulated inside the hollow cores of carbon nanotubes (CNTs) have been experimentally synthesized and structurally characterized by Raman spectroscopy and transmission electron microscopy. However, in terms of electronic conductivity, their transportation mechanism has not been investigated theoretically or experimentally. In this study, the density of states and quantum conductance spectra were simulated through density functional theory combined with the non-equilibrium Green function method. The encapsulated LCCs inside (5,5), (6,4), and (9,0) single-walled carbon nanotubes (SWCNTs) exhibited a drastic change from metallic to semiconducting or from semiconducting to metallic due to the strong charge transfer between them. On the other hand, the electronic change in the conductance value of LCCs encapsulated inside the (7,4) SWCNT were in good agreement with the superposition of the individual SWCNTs and the isolated LCCs owing to the weak charge transfer.

Place memory is a new way of seeing as a new concept of cultural landscape research. Various research works and discussions have recently spread in landscape studies. In particular, the, which is visible and material, is a medium in which collective memory is embedded in place memory. The purpose of this study is to extract places of memory from the collective memory of residents of Janghang, Korea, and to visualize it through semantic relations. For this purpose, semi-standardized interviews (34 persons) were conducted with residents, and frequency analysis and semantic network analysis were used. As a result, the interviewees recalled only 127 places in Janghang that existed between 1920 and 2010. Locals remember the city based on places of memory. This means that the city could be illustrated according to specific places that are frequently mentioned. For instance, the top 25 places (top 20%) explain 65.6% of all the places in the city, and the top 39 places (top 30.8%) could describe 78.7% of the places. Some places are referred to more frequently when they are in the city’s symbolic landscape, and the city’s identity is projected on them. Some places were mentioned only infrequently but were nevertheless very important places by which to understand Janghang. These places of memory have not appeared in the documentary records before, which shows the value of the collective memory of the locals and the effectiveness of the interviewing method. In the clustering of the semantic network, six groups of places appeared. The local residents remembered the modern industrial city and recalled it in connection with the sites of daily life. This shows the possibility of looking not only at public memory and famous heritage as a macro history but also at daily life and meaningful places as a micro history about locals. This study has significance as an initial research that identified and visualized places of memory from the perspective of local residents. Such an approach could be useful in the study of everyday life and the conservation of modern heritage.

Pilot Aptitude Research Equipment (PARE) is a simulator developed to measure or research pilot aptitude and train for student pilots. Design of an ergonomic PARE operation console is required to operate the equipment effectively. This study carried out five steps : (S1) operator questionnaire survey, (S2) anthropometric design formula development, (S3) usability evaluation, (S4) improvement design, and (S5) validation considering both Physical User Interface (PUI) and Graphic User Interface (GUI) of PARE operation console. The operator questionnaire surveyed needs for each PUI and GUI part of the console from two PARE actual operators. In terms of PUI, the anthropometric design formula was developed by using design variables, body dimensions, target population characteristics, and reference posture related to the PARE console. In terms of GUI, the usability evaluation was conducted by three usability testing experts with a 7-point scale (1 : very low, 4 : neutral, 7 : very high) on GUI of the PARE operation console by seven usability criteria. The improved PARE operation console was designed to reflect the optimal values of design variables calculated from design formula, the results from usability testing, and the operator’s needs. The improvement effect was observed by 20 people who had experience with the PARE operation console. As a result of the validation, monitor visibility and cockpit visibility for the improved PUI design and visibility and efficiency for the improved GUI design were significantly increased by more than 90% respectively. The improved design of the PARE operation console in this study can contribute to enhance operation performance of the PARE.

The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

This paper studied balanced regional development focused on employment in Korea, by analyzing regional disparity between regional and industrial employment. A Gini-coefficient decomposition method and Panel Granger causality test were conducted, using raw data of the Census on Establishments reported by the Statistics Korea. The regional and industrial disparity of employment, based on the Gini-coefficient decomposition method, have increased by year. However, the growth rates of disparity are on the decrease. Most of employment disparity occurred from regional disparity between SMA (Seoul Metropolitan Area) and Non-SMA. Industrial disparity are occurred mainly by the service industry. The amount of contribution to the whole disparity of inter/intra regional employment was differed by each industrial sector. Also the causal relationship between employment growth of manufacture and that of service industry was analyzed by Panel Granger causality test. In national level, the employment growth in manufacture industry has conduced that in service industry. On the other hand, in the Non-SMA, only the employment growth in manufacture industry has augmented that in service industry. In conclusion, to reduce employment disparity, the strategy for balanced regional development should be emphasized. Different strategies are needed across regions and industries. Basically creating new job in the Non-SMA is inevitable. In view of stable employment, manufacture industry is more desirable rather than service industry.

High quality and timely assessment feedback is central to student learning in higher education; however, written feedback has many limitations. One of the innovative approaches to delivering feedback to EFL learners is individualized audio-visual feedback (AVF) using screencast technology. Previous research on AVF has been extensively descriptive and mostly focused on student preferences for feedback and evaluation of various screencast software. The present study employed a mixedmethod design using pre-post writing tasks and pre-post questionnaires to investigate what particularly beneficial affordances this type of media-rich feedback might offer for writers in the English-Medium Instruction (EMI) classroom, to identify the effects of AVF on changes in learners’ motivation, and to explore students’ perceptions towards screencast feedback. The results suggest that AVF is positively received by EFL learners and that simultaneous visual cues and detailed explanations promote better understanding, engagement, and active listening. In addition, AVF significantly improves learners’ writing performance and academic motivation. The paper concludes with practical implications and suggestions for further research.

The Kazak honorific system has been described to consist of a number of second person forms and terms of address. In addition to these core honorific expressions, however, my recent study of spoken Kazak in the Chinese Altai reveals that there are many other politeness features — both linguistic and non-linguistic — that constitute a loosely integrated honorific register system. They include grammatical distinctions (e.g., singular/plural, past/perfect, confirmative/non-confirmative), lexical distinctions (e.g., Chinese titles/Kazak kin terms), prosody (e.g., loud/quiet, fast/slow), as well as non-linguistic features (e.g., smoking/ non-smoking, male facial hair grown/removed, serving of black tea/milk tea). This paper describes these “non-core” expressions and the semiotic processes in which they, together with the core expressions, form a dichotomous system of contrast between plain and honorific registers.

Many countries around the world have been pursuing the mission to fulfill the right to education of persons with disabilities. The usage of ICT has been well recognized internationally as essential to foster education, access to information and knowledge, and assist in the learning and teaching process. Furthermore, ICT has the great potential to ensure inclusion for persons with disabilities. The Government of Mongolia has been making efforts toward ensuring inclusion. However, the integration of ICT in schools for students with disabilities still needs further development through proper ICT policy. Therefore, this study intended to formulate the major principles of ICT Policy for improving ICT integration in education to meet the needs of students with disabilities. In this study, the content analysis of 39 academic articles from the period of 2006-2018 has been conducted in order to identify the best practices from other countries and find the applicable ones to Mongolia. As a result of this study, 7 principles have been formulated to improve ICT integration in education for students with disabilities in Mongolia.

Modern society has become an aging society, and the National Statistics Office(NSO) expects that Korea will be also an aging society by 2019, that is, people over the age of 65 will account for 14 percent from the total population. In addition, the increase of labor flexibility is also one of the dramatic features in modern society. However, this social shift have unpredictable results, that is, the advent and increase of grandparent and grandchildren family. Modern medical technology has given Koreans longer expectancies, and structural and economic changes in society have brought early retirement. One of the main reasons that grandparent and grandchildren family increase is below an average of two children per family. There are various services available such as Health support center, Dream start center, Youth support center, Community child center, and Community welfare center. Besides, schools operates various programs for grandparent and grandchildren family with social workers and school counselors. But, most of all, what is necessary is a change of perspective on them. Basically, we need to develop a clear perspective on grandparent and grandchildren family as a not dismantling family type but alternative family type with creating a separate program or service

With industrialization, environmental problems have become severe worldwide as resources are exhausted for mass production purposes and pollutants are produced in excess of nature's capacity to absorb them. Since modernity, urban parks have emerged as an important element for addressing challenges facing urban environments, which include environmental degradation. In 1987, the Brundtland Commission’s report presented a sustainable developmental perspective in solving environmental problems and provided ideas for sustainable design and sustainable urban park landscape design. The purpose of this study is to analyze sustainable design applied to Houtan Park in central Shanghai, China from the perspective of social culture preservation, ecological restoration, and economic effect, and to provide the basic data for urban park design in similar areas in the future. This study consists of a literature survey and a field investigation. The field investigation lead to analysis from three perspectives: social culture preservation, ecological restoration, and economic effect. The literature survey examined sustainable urban parks and Houtan Park based on relevant papers, newspaper articles, and reports. Through actual visits (Aug. 28 - Sep. 1, 2018), it also examined the elements of sustainable design that were applied to the architecture. The three sustainable design elements derived from this study, being a sustainable design for the future, will be used as an important basis for developing urban parks for the regeneration of brownfields in many areas in China.

Due to changes in the agricultural market environment and both overseas and domestic farming conditions, uncertainties in agricultural production and management are becoming greater. Hence, there is a stronger need for farmers to choose crops in the optimal condition. This research aims to introduce the result and process of developing a decision support system for selecting crops, aimed to assist farmers in selecting the optimal crops most suitable in the given situation. There are basically three main factors to consider in the decision-making process for farmers when selecting a crop to introduce to their lands. First of all, one must consider how much profit crop A will produce when it is cultivated. Secondly, one must consider which crop to cultivate in order to earn a certain amount of profit. Thirdly, one must consider what is the best way to maximize Farm A’s business profit. For instance, a farm may have land as its resource, and one must research which location, type of crop, level of technology, and so forth, to maximize profit.This research creates a database of the profitability of a total of 180 crop types by analyzing Rural Development Administration’s survey of agricultural products income of 115 crop types, small land profitability index survey of 53 crop types, and Statistics Korea’s survey of production costs of 12 crop types. Furthermore, this research presents the result and developmental process of a web-based crop introduction decision support system that provides overseas cases of new crop introduction support programs, as well as databases of outstanding business success cases of each crop type researched by agricultural institutions.

The study investigated the effects of recasts and prompts on learning language forms that arose incidentally in dyadic interaction, focusing on the degree of explicitness of each type of feedback and learner proficiency levels. The data were collected from 64 beginning and upper-intermediate English learners of Korean. Thirty-one beginning learners were randomly assigned to a feedback group and to a control group, and thirtythree upper-intermediate learners were also assigned to a feedback group and to a control group. Each learner was paired with an English speaker and worked on a picture-sequencing task. The learners in the feedback groups received recasts or prompts on their erroneous utterances while the learners in the control groups did not. The effects of feedback were measured by pre-interaction picture descriptions and immediate and delayed post-interaction correction tasks. The study found that both recasts and prompts had some effects on learning the targeted forms, and more explicit forms of each feedback resulted in a higher rate of correction. The beginning learners took more advantages of recasts relative to the upper-intermediate learners, and explicit prompts worked better for the upper-intermediate learners. The effects of prompts sustained longer than recasts in both levels.
