  • Sustainability science is an emerging transdisciplinary research which necessitates not only the communication and collaboration of scientists, practitioners and stakeholders from different disciplines and interests, but also the paradigm shift from deterministic and reductionist approaches to the old basic. Ecological-societal systems (ESS) are co-evolving complex systems having many interacting parts (or agents) whose random interactions at local scale give rise to spontaneous emerging order at global scale (i.e., self-organization). Here, the flows of energy, matter and information between the systems and their surroundings play a key role. We introduce a conceptual framework for such continually morphing dynamical systems, i.e. self-organizing hierarchical open systems (SOHOs). To understand the structure and functionality of SOHOs, we revisit the two fundamental laws of physics. Re-interpretation of these principles helps understand the destiny and better path toward sustainability, and how to reconcile ecosystem integrity with societal vision and value. We then integrate the so-called visioneering (V) framework with that of SOHOs as feedback/feedforward loops so that 'a nudged self-organization' may guide systems' agents to work together toward sustainable ESS. Finally, example is given with newly endorsed Sustainable Development Goals (SDG) Lab (i.e., 'Rural systems visioneering') by Future Earth, which is now underway in rural villages in Tanzania.

  • This study is about Yoo Young-kuk's early works which show constructivism, especially focus on his debut painting, for the 7th Dokuritsu Bijutsu Kyokai(獨立美術協會, the Independent Fine Arts Association) in Tokyo in 1937. The work was painted 2 years after he had started his study in Japan in 1935. It was the first painting that applied Constructivism. played an important role for Constructivism to be a leading art in his abstraction. After this picture, Yoo was soon devoted to the principles of Constructivism-- Faktura(material), Tektonika (tectonics), Tekhnika(technique), space, construction-- in his painterly reliefs. This article examined why Yoo concentrated on Constructivism for , what the characteristics were, and what influences were on other works from 1935 to 1949. In addition, I investigated in which period was painted and how Constructivism was spread in 1930s and early 1940s in chapter 2. I scrutinized Rhapsody in chapter 3. When Yoo created Japan was under the Fifteen Years War(1931-1945), and a major discourse was the Japanese Spirit at that time. It was connected with construction of an ideal nation which the Japanese ultra-national fascism pursued. This ideological pursuit was intended to unite the Japanese people for total war system and to restore a national dignity which had been fallen down due to Manchurian Incident(1931). Thus, on the hand, Kokusai Bunka Shinkokai(國際文化振興, The Society for International Cultural Relations) and the Nippon Kosaku Bunka Renmei(日本工作文化連盟, Japanese Werkbund) were supported financially by the Japanese government. On the other hand, the government enacted regulations to opposing parties which would distract Japanese people's unification. As for the Japanese art world, the merge of art groups was carried out through remodeling of Teikoku Bijutsuin(帝國美術院, The Imperial Fine Arts Academy) in 1935. This brought out continuous dispute and disorder. Young artists who felt difficulty of entering an entry of Imperial Fine Arts Exhibition repeatedly grouped and disbanded for small art groups to build their standing, which they pursued Surrealism and Abstract art. Among them Constructivism was considered as the latest trend and was popular in craft, design, architecture as well as fine arts. In the year before he painted , Avant-garde theatres including Constructivism theatre were introduced in a feature article of September, 1936 in Atelier, which was dealing with mainly avant-garde arts. Books related with Constructivism were translated into Japanese, and Gestaltung Education had become active since the publication of A Compendium of Gestaltung Education("構成敎育大系"(1934)), Salvador Dali(1904-1989) was also introduced, so Surrealism was drawn more attention by young artists. reflected popular trends. Yoo analyzed the Japanese avant-gardists' archaic taste in the Independent Art Association that he submitted his painting to. And then he entitled 'Rhapsody' which derives from Ancient Greek's epic poetry and deliberately set up images in a scene. In chapter 3, I examined a theme which was planned carefully by sorting favorite images from the Japanese Surrealism. was a result that Yoo Young-kuk observed objectively the phenomenon that young artists dreamt of Utopia or longed for Nostalgia passively and lethargically under wars. And then he otherized himself from that circumstance. First of all, for he used the typical icons of Japanese Surrealism such as the horizon, flowing clouds, and vast plain that were considered stereotypes of Arcadia. He, however distinguished himself form those Japanese Surrealists. He made his own vision about Utopia by referring Lyubov Popova(1889-1924)'s stage design. His objective point of view was expressed by positive and dynamic images of structure and human's actions. Constructivism which was attempted in had an effect on other early constructive works, and the principles of Constructivism were sought hard in reliefs, paintings, and photos.

  • In the radical char]go of the business environments that the existing facilities can not guarantee the business-frosts anymore, enterprises have been importing ERP system. In Korea, Sam-sung Electronics did it for the first tin in the latter half of 1994 and other enterprises succeeded. Currently, government and public enterprises as well as most of the large enterprises are employing ERP system to sharpen the competitiveness and to win the business transparency. On the other hand, it is harder for small and medium enterprises shaded by the large enterprises to be well-equipped with information system such as ERP, because they have already suffered from chronic financial difficulties and shortage of many resources. Most of all, they prefer the short-term project that does not need much tine for them to make decisions and to carry out fully. Grounded on the above factors, in this work, I suggest the suitable ERP model for the small and medium enterprises and the successful importing process of ERP, which is derived from the previous researches made by other masters' thesis. If necessary information and human resources are interchanged pertinently between local education institute and small and medium enterprise, the latter could not only deal with the confronted difficulties successfully inside and outside but attain the goal of being proficient in up-to-minute high technology. Besides, giving the students the opportunity of researching into the practice of the business they have not ever known, local universities could help their students accumulate knowledges and acquire ideas which could not be achieved in pure academic studies. When the above-mentioned procedure is over, the students might get the intellectual faculty to ponder on the future more concretely and enter a profession more carefully. In the result, we would raise up the percentage of the employment among the graduates. And active participation of university professors is the last important factor that assists the small and medium enterprises for introducing ERP system successfully. Their scholarly attainments play an important role in strengthening local economy and make the business competitiveness balanced between the capital and the local economy.

  • Various theories and techniques for the subject catalog have been developed since Charles Ammi Cutter first tried to formulate rules for the construction of subject headings in 1876. However, they do not seem to be appropriate to Korean language because the syntax and semantics of Korean language are different from those of English and other European languages. This study therefore attempts to develop a new Korean subject indexing system, namely Korean String Indexing System(KOSIS), in order to increase the use of subject catalogs. For this purpose, advantages and disadvantages between the classed subject catalog nd the alphabetical subject catalog, which are typical subject ca-alogs in libraries, are investigated, and most of remarkable subject indexing systems, in particular the PRECIS developed by the British National Bibliography, are reviewed and analysed. KOSIS is a string indexing based on purely the syntax and semantics of Korean language, even though considerable principles of PRECIS are applied to it. The outlines of KOSIS are as follows: 1) KOSIS is based on the fundamentals of natural language and an ingenious conjunction of human indexing skills and computer capabilities. 2) KOSIS is. 3 string indexing based on the 'principle of context-dependency.' A string of terms organized accoding to his principle shows remarkable affinity with certain patterns of words in ordinary discourse. From that point onward, natural language rather than classificatory terms become the basic model for indexing schemes. 3) KOSIS uses 24 role operators. One or more operators should be allocated to the index string, which is organized manually by the indexer's intellectual work, in order to establish the most explicit syntactic relationship of index terms. 4) Traditionally, a single -line entry format is used in which a subject heading or index entry is presented as a single sequence of words, consisting of the entry terms, plus, in some cases, an extra qualifying term or phrase. But KOSIS employs a two-line entry format which contains three basic positions for the production of index entries. The 'lead' serves as the user's access point, the 'display' contains those terms which are themselves context dependent on the lead, 'qualifier' sets the lead term into its wider context. 5) Each of the KOSIS entries is co-extensive with the initial subject statement prepared by the indexer, since it displays all the subject specificities. Compound terms are always presented in their natural language order. Inverted headings are not produced in KOSIS. Consequently, the precision ratio of information retrieval can be increased. 6) KOSIS uses 5 relational codes for the system of references among semantically related terms. Semantically related terms are handled by a different set of routines, leading to the production of 'See' and 'See also' references. 7) KOSIS was riginally developed for a classified catalog system which requires a subject index, that is an index -which 'trans-lates' subject index, that is, an index which 'translates' subjects expressed in natural language into the appropriate classification numbers. However, KOSIS can also be us d for a dictionary catalog system. Accordingly, KOSIS strings can be manipulated to produce either appropriate subject indexes for a classified catalog system, or acceptable subject headings for a dictionary catalog system. 8) KOSIS is able to maintain a constistency of index entries and cross references by means of a routine identification of the established index strings and reference system. For this purpose, an individual Subject Indicator Number and Reference Indicator Number is allocated to each new index strings and new index terms, respectively. can produce all the index entries, cross references, and authority cards by means of either manual or mechanical methods. Thus, detailed algorithms for the machine-production of various outputs are provided for the institutions which can use computer facilities.

  • Two-pore domain potassium (K2P) channels are the targets of physiological stimuli, such as intracellular pH, bioactive lipids, and neurotransmitters, and they set the resting membrane potential. Some types of K2P channels play a critical role in both apoptosis and tumoriogenesis. Among the K2P channels, no antagonists of the TREK2 channel have been reported. The aim of the present study was to determine if the TREK2 channel is blocked and whether cell proliferation is influenced by flavonoids in the TREK2 overexpressing HEK293 cells (HEKT2). The electrophysiological current was recorded using single channel patch clamp techniques and cell proliferation was measured using a XTT assay. The electrophysiological results showed that the TREK2 channel activity was reduced to $91.5{\pm}13.1%$ (n=5) and $82.2{\pm}13.7%$ (n=5) by flavonoids, such as epigallocatechin-3-gallate (EGCG) and quercetin in HEKT2 cells, respectively. In contrast, the EGCG analogue, epicatechin (EC), had no significant inhibitory effects on the TREK2 single channel activity. In addition, cell proliferation was reduced to $69.4{\pm}14.0%$ (n=4) by ECGG in the HEKT2 cells. From these results, EGCG and quercetin represent the first known TREK2 channel inhibitors and only EGCG reduced HEKT2 cell proliferation. This suggests that the flavonoids may work primarily by inhibiting the TREK2 channel, leading to a change in the resting membrane potential, and triggering the initiation of a change in intracellular signaling for cell proliferation. TREK2 channel may, at least in part, contribute to cell proliferation.

  • Magnetization Transfer (MT) imaging generates contrast dependent on the phenomenon of magnetization exchange between free water proton and restricted proton in macromolecules. In biological materials in knee, MT or cross-relaxation is commonly modeled using two spin pools identified by their different T2 relaxation times. Two models for cross-relaxation emphasize the role of proton chemical exchange between protons of water and exchangeable protons on macromolecules, as well as through dipole-dipole interaction between the water and macromolecule protons. The most essential tool in medical image manipulation is the ability to adjust the contrast and intensity. Thus, it is desirable to adjust the contrast and intensity of an image interactively in the real time. The proton density (PD) and T2-weighted SE MR images allow the depiction of knee structures and can demonstrate defects and gross morphologic changes. The PD- and T2-weighted images also show the cartilage internal pathology due to the more intermediate signal of the knee joint in these sequences. Suppression of fat extends the dynamic range of tissue contrast, removes chemical shift artifacts, and decreases motion-related ghost artifacts. Like fat saturation, phase sensitive methods are also based on the difference in precession frequencies of water and fat. In this study, phase sensitive methods look at the phase difference that is accumulated in time as a result of Larmor frequency differences rather than using this difference directly. Although how MT work was given with clinical evidence that leads to quantitative model for MT in tissues, the mathematical formalism used to describe the MT effect applies to explaining to evaluate knee disorder, such as anterior cruciate ligament (ACL) tear and meniscal tear. Calculation of the effect of the effect of the MT saturation is given in the magnetization transfer ratio (MTR) which is a quantitative measure of the relative decrease in signal intensity due to the MT pulse.

  • ESRRB (Estrogen related receptor $\beta$) is an orphan receptor, and have a role on maintaining the undifferentiated state and self-renewal of pluripotent stem cell as a transcription factor which regulates the expression of OCT4 and NANOG genes. Also, Feng et al. (2009) reported that Esrrb, Oct4 and Sox2 could induce pluripotent stem cell from somatic cells. The aim of the present study was to develop the direct delivery system of human ESRRB protein into human amniotic fluid-derived stem cells (AFSCs) and to analyze the effect of ESRRB on the regulation of pluripotency-related genes. Human ESRRB has three isoforms arisen by alternative splicing. We cloned short-form ESRRB and made a fusion protein of ESRRB and R7 for an efficient protein transfer to cell. R7 as cell-penetrating peptide(CPP) can help to transfer ESRRB into cells. R7-ESRRB-His6 protein was observed in the cytoplasm and nuclei within 5 hours after treatment. Also, we could observe R7-ESRRB-His6 protein only in the nuclei within 24 hours. Realtime PCR showed that ESRRB increased expression of OCT4 and NANOG as well as SOX2 gene. Therefore, we demonstrated that R7-ESRRB-His6 proteins were efficiently transferred into the nuclei of AFSCs and work well as a possible transcription factor.

  • As contest exhibits have been activated, a variety of organizations are holding contest with various purposes. Analysis on the guidelines prepared by various sponsoring bodies ranging from public organizations to privately owned businesses shows that sponsoring bodies tend to possess copyrights of entries. Parts of guidelines of contest exhibit are the contract. While sponsoring body shows its opinion on copyright through guidelines, individual participant tends to consider it simply as a form to submit for contest exhibit rather than a contract. Now is the time to bring out a question in respect of the copyright on the contest exhibit. The important fact is that copyright on corporate contents is important, but copyright on individual contents is equally important and it must be protected and respected. This study aims to bring out a question on copyright by analyzing possession and infringement of copyright that stands forth in the guidelines of contest exhibit. Provisions on copyright of contest exhibit play a role as a contract. Provisions on copyright of contest exhibit shall be the ones which can be understood and accepted by both sponsoring body and winner who are the A and B of a contract. For this, change in perception of sponsoring bodies ranging from public organizations to privately owned businesses with prominent position is strongly required. For the foregoing, First, Indication of Copyright: Clear and concrete terms must be used. Second, Scope of Interpretation: Concrete and detailed indication must be made for preventing indication that allows comprehensive interpretation. Third, Cost for Author's Property Right: In case sponsoring body needs to possess or use the author's property right of prize-winning work, proper rights on use considering prize money corresponding to possession or use of author's property right must be indicated. Fourth, Term of Use: The term for using author's property right must be indicated. Fifth, Scope of Rights: The scope of author's property right that sponsoring body requires must be limited and indicated. Sixth, Mutual Respect: Items related to copyright must be indicated on the basis of the concept of bilateral contract founded on mutual consideration and respect, not on the concept of unilateral contract.

  • Objectives : To observe changes in the serum proteins before and after intravenous injection of wild ginseng herbal acupuncture. Methods : Blood was collected before and after the administration of wild ginseng herbal acupuncture and only the serum was centrifuged. Then differences in the spots on the scanned image after running 2-Dimensionl electrophoresis were located and conducted mass analysis and protein identification. Results : Following results were obtained from the comparative analysis of serum proteins before and after the administration of wild ginseng herbal acupuncture. 1. 28 spots were identified before and after the administration. 2. In confirming manifestation degree, spots with more than two-times increase were 204, 803, 1505, 2205, 3105, 7104, 9001 spots, with more than one-time increase were 1101, 1302, 2013, 3009, 3010, 4002, 4009, 6706, 7103, 8006, 8101, and spots with decrease were 205, 801, 3205, 5202, 6105. 3. After conducting protein identification, proteins 205, 804, 1302, 4009, 6105, 6106 are unidentified yet, and 1101 is unnamed protein. Protein 204 is identified as complement receptor CR2-C3d, 801 as YAP1 protein, 803 as antitrypsin polymer, 1505 as PRO0684, 2013 and 3010 as proapolipoprotein, 2205 as USP48, 2403 as vitamin D binding protein, 3009 as complement component 4A preprotein, 3105 as immunoglobulin lambda chain, 3205 as transthyretin, 4002 as Ras-related protein Ral-A, 4204 as beta actin, 5202 and 7104 as apolipoprotein L1, 6704 as alpha 2 macroglobulin precursor, 7103 as complement component 3 precursor, 8006 as testis-specific protein Y, 8101 as Transferrin, 9001 as(Alpha-Oxy, Beta-(C112g)deoxy) T-State Human Hemoglobin, and 9003 as human hemoglobin. 4. Immune protein CR2-C3d, which acts against microbes and pathogenic organisms, and Antitrypsin(803), which is secreted with inflammatory response in the lungs, were increased by more than 200% after the administration of herbal acupuncture. 5. Immunoglobulin lambda chain(3105), Alpha-Oxy, Beta-(C112g)deoxy T-State Human Hemoglobin(9001), and human hemoglobin(9003) were increased by more than two-times after the administration of herbal acupuncture. 6. Proapolipoprotein(2013, 3010) and apolipoprotein(7104), key components of the HDL-cholesterol which plays an important role in preventing arteriosclerosis, were increased after the administration of herbal acupuncture. 7. Vitamin D binding protein(DBP, 2403), protecting the lung at the time of inflammatory response, was increased after the administration of herbal acupuncture. 8. Transthyretin(TTR, 3205), which is the main protein causing familial aimyloid polyneuropathy(FAP), was decreased after the administration of herbal acupuncture. 9. Ras-related protein Ral-A(4002) that controls phospholipid metabolism, cytoskeletal formation, and membrane traffic, was increased after the administration of herbal acupuncture. 10. Testis-specific protein Y(8006), which takes part in determination of the gender, was increased by more than two-times after the administration of herbal acupuncture. 11. Transferrin(8101), T-State Human Hemoblobin(9001), and Human Hemoblobin(9003) which balances the iron level in the body, were increased after the administration of herbal acupuncture. Conousion : Above results support the notion that intravenous injection of cultivated wild ginseng herbal acupuncture induce changes in serum proteins and this research can be a pioneer work in finding biomarkers.

  • Objectives : Outpatient treatment orders refer to a mandatory social program in which mentally ill persons are ordered by the court to participate in specified outpatient treatment programs. This study aimed to investigate the factors that affect outpatient treatment orders and adherence to outpatient treatment in mental health patients. Methods : A survey on outpatient treatment orders and adherence to outpatient treatment was conducted on 60 psychiatrists between October and November 2016. The questionnaire items were drafted based on a literature review, and they were then evaluated by 3 psychiatrists and 1 law school professor before being finalized. Answers from the respondents were analyzed using descriptive statistics, and the median, maximum, and minimum values of the effectiveness scores of outpatient treatment orders were calculated. Results : Among the 60 psychiatrists, 45(75.0%) were aware of outpatient treatment orders; however, only 2 out of the 45(4.0%) had actually used the program in the last 12 months. The subjective effectiveness was very low, with only 40 points out of 100. Furthermore, of the readmitted patients, 37.7% had received continued outpatient treatment, whereas 53.1% chose to quit the outpatient treatment programs, meaning that the number of dropouts was higher. Among the discharged patients, approximately two-thirds were receiving continued treatment. With regard to follow-up for dropouts, majority of the responses were either "Not taking any action"(n=27) or "Not following up"(n=15). Only two respondents answered "Contact the community mental health promotion center," meaning that this response was very rare. Meanwhile, when asked about efficient measures to be implemented for dropouts, a vast majority of the respondents(n=30) selected the answer "Work with the community mental health promotion center." Conclusions : The outpatient treatment orders currently being administered were found to be ineffective, and the associated adherence to outpatient treatment was also found to be extremely poor. Hence, the effectiveness of the therapeutic interventions could benefit from institutional as well as administrative improvements. Community mental health promotion centers are expected to have an important role in the future.
