  • Design takes concrete form from the things which are not yet exist to the molded reality. Creation of value which is accompanied by the rational value could be possible only through the searching examination of the basic concept. All designs are under circumstances because the results and the character of the problems are different under the given conditions and circumstances which are the characteristic of the design. The aim of this study is searching for the differential design conce- pt which is the most appropriate and reasonable in the basic design process in which the phase of the analysis, synthesis and evaluation of the problem. First of all the pursuit value of the times and the change of the view point of value of the product design. How the pursuit value of times were searched and analyzed. Analyze the successful product design realization of the typical trend of the modern design which are 3-2. function-focused design, 3-3. emotion-centered design, 3-4. image communicative design through the metaphor, 3-5. environmental affinity design. On the base of the case analysis how to apply the differential design concept which is coming as a trend in the future society which are sustainable developing society was examined closely. The outcome through the analysis of the success cases are as follows, \circled1 the value of the spirit of the times should be emphasized as the design image, \circled2 environmental appropriateness should be taken into consideration as the first primary factor, \circled3 the realization of value of the fulfillment of differential consumer's needs, \circled4 lead to prolong the life cycle of the product, \circled5 promote the sustaining growth of enterprise, \circled6 user-centered product value should be the first consideration. \circled7 It is necessary to overcome the cultural andinguistic barriers and to reflect the metaphor which people remember well. \circled8 The application of human's true character should be decided beforehand. It is the commonness of values of times and customs. \circled9 The differentiated design concept which meets our mental satisfaction, not material one, will be required. In addition to this the creative and differentiated design concepts which are accompanied by the good design factor under the base of product could achieve the emotional consensus from the consumers. That is, the value of all designs should be estimated by the base of the humanism ' The human beings are the barometer of all things".ngs".uot;.

  • Cancer is a complex disease heterogeneously composed of various types of cells including cancer stem-like cells responsible for relapse and chemoresistance in the tumor microenvironment. The conventional two-dimensional cell culture-based platform has critical limitations for representing the heterogeneity of cancer cells in the three-dimensional tumor niche in vivo. To overcome this insufficiency, three-dimensional cell culture methods in a scaffold-dependent or -free physical environment have been developed. In this study, we improved and simplified the HCT-8 colon cancer cell-based spheroid culture protocol and evaluated the relationship between cancer stemness and responses of chemosensitivity to 5- Fluorouracil (5-FU), a representative anticancer agent against colon cancer. Supplementation with defined growth factors in the medium and the culture dish of the regular surface with low attachment were required for the formation of constant-sized spheroids containing $CD44^+$ and $CD133^+$ colon cancer stem cells. The chemo-sensitivities of $CD44^+$ cancer stem cells in the spheroids were much lower than those of $CD44^-$ non-stem-like cancer cells, indicating that the chemoresistance to 5-FU is due to the stemness of colon cancer cells. Taken together, the inflammation and oncogenic gut environment-sensitive HCT-8 cell-based colon cancer spheroid culture and comparative evaluation using the simplified model would be an efficient and applicable way to estimate colon cancer stemness and pharmaceutical response to anticancer drugs in the realistic tumor niche.

  • Jungchull(정철) was a very famous poet of Kasa(가사), Sijo(시조) and Hansi(한시) during the middle period of the Chosun kingdom. He has been studied by modern scholars mainly as a poet of Kasa(가사). These days, however, his Sijos are being studied as an important literary achievement. The purpose of this study is to analyze the pursuit of reality and elegance expressed in Jungchull's Sijo in order to understand his Sijos more deeply. In the process of this discussion, I will take a look at some of his Kasa(가사), Hansi(한시) and biography also, and I will compare his Sijo(시조) with that of his teacher's, friend's and senior's. Jungchull considered it important to become an official in the royal court because he was a Confucian scholar who believed in jugi-theory (주기론), in which all realistic phenomena is evaluated(Confucianism is very realistic in essence), and he had a happy life in the royal household until he was ten years old. I found that characteristics of his "realistic pursuit" are represented in his Sijo by two situations: the one is when he is apart from the King, and the other when he is together with the King. In all situations, though, he pursued an official position in the royal court. When he was apart from the king, his absolute resolution to follow the King was expressed in his not being able to sleep. In his sijo, he asks the wild duck to inform him of the King's welfare. He tries to flap his wings, to be the water or the moon in order to reach the royal household where the King was living. When he recognizes it's impossible, he expresses his perfect loyalty to the King in his Sijo by using literary paradox. According to this, he describes himself as not an able scholar, but also not a flattering scholar. In his sijo, he reminisces about working for the King in the royal household, when he had a good relationship with the King. But when he was an official in the province in a good relationship with the King, he expressed his intention of coming back to the royal household in order to be with the King again. From this we can ascertain that his pursuit of reality means to occupy an official position in the royal household, to serve the King and to have political power among of the officials. His elegance, expressed in his sijo, is deeply related to his absolute political pursuit of the King. He describes two kinds of elegance: nature related elegance and drinking alcohol related elegance. Two kinds of nature related elegance were delineated in his sijo, depending upon his political situation. When he had a good relationship with the King, occupying an official position, he delineated his gladness and free-heart in harmonizing with nature. But when he lost his official position. he expressed his purity using nature, and exclusion from nature. These kinds of nature related elegance were different from that of the usual Confucian scholar, for example, contemporaries Lee Hwang Next, two kinds of drinking alcohol related elegance were delineated in his sijo depending upon his political situation. More often he depicted excitement and composure of mind in his sijo by drinking alcohol in good situations than in efforts to overcome his agony in bad situations. The tradition of overcoming one's agony by drinking alcohol in bad situation was discovered by this writer in Jungchull's teacher's, and also his junior's sijo. Lastly in my next research paper future, I will look at the reason why certain various themes are represented in Jungchull's sijo, and what their the relationships are, to understand his literary works as a whole.

  • The purpose of this study was to investigate the Asynchronous development of young gifted children by parents' perception. Total 3 groups of 145 subjects from age 30 months to 6 years 10 months old young gifted children's parents participated. The major findings were as follows: (1) The mean developmental characteristics was at a high average level. The developmental subscales tended to be high. The level of verbal understanding/expression tended to be high. It reared as followed; intellectual capacity, emotional maturity, visual-motor coordination, morality, self-behavior control, emotion control, physical development, social development, peer relationship, leadership ability. (2) There were significant differences between intellectual capacity, verbal understanding /expression and physical, social development, self-behavior control, emotion control. There were significant differences between physical development, self-behavior control and emotion control as children got lower. There were significant differences between verbal understanding/expression and visual-motor coordination as children got older. There were significant differences between social development, peer relationship and self-behavior control, emotion control as children got older. Also, there were significant differences between leadership ability and self-behavior control, emotion control as children got older. There were significant differences between morality and self-behavior control as children got older. These findings suggested that young gifted children were in the special needs because of the developmental differences.

  • The purpose of this study was to verify how the vocational education for training industrial workforce as a national human resource development (NHRD) system has undergone a transition process in relation to the national economic, industrial, and socio-cultural contexts. First, how vocational education as an industrial workforce training system has changed in accordance with Korea's economic environment, industrial development, and social changes; second, what are the main factors that influenced the role and importance of vocational education; and third, vocational education as a system for training industrial workforce and training workforce in science and engineering were analyzed differently from the perspective of the NHRD model. To this end, domestic and international academic journal papers, research reports, and thesis were investigated and classified by period, and major changes in vocational education were analyzed in relation to economic, industrial, and social issues and policies by period. As a result of the research, first, as the industry advanced, the level of vocational education increased and the scope expanded. Second, vocational education tended to shrink gradually after the manufacturing industry base, and especially secondary vocational education tended to decline after the national industry focused on light industry. Third, since the 1970s, the diversification of the NHRD and jobs has resulted in wage gaps depending on the level of education, which has increased the preference for university education and avoided secondary vocational education. In addition, a NHRD model focusing on training science and engineering workforce was proposed to compare the existing NHRD model focusing on overall vocational education, and it was revealed that the NHRD needs to be subdivided into various fields or levels to derive a model and examine changes. From the results of the study, vocational education in Korea, especially in secondary vocational education, has declined due to large impacts on socio-cultural perception due to economic growth, enthusiasm for education, and external shocks such as the financial crisis, and the long-term effort to change this perception is suggested to overcome the crisis of vocational education.

  • Through a story, the audience moves between fiction and reality. A story is an emotional experience that appeals to human feeling. The rational function of a story is to convey knowledge and information, and its emotional function is to touch the audience. Moreover, these aspects of a story are linked to its language, text, and imagery. This paper focuses on the emotional function of a story. In a experiential story, the audience's emotional response is a result of maximum dramatic communication between them and the characters. Through psychological and mental communion with the characters, the audience becomes immersed in the story when they emotionally identify with the characters, and dramatic communication is achieved. However, dramatic communication is mostly achieved instantaneously. The elements of a film need to be realized to sustain dramatic communication such that the audience continues to be immersed in the story. The audience can identify with the characters who are placed in real-life situations by considering the characters' external and internal aspects. External search pertains to the tangible aspects of the character such as its background, life, and conversation. Through the audience's external search, the characters communicate with the audience. Internal search deals with aspects of the characters' personality such as their self-concept, desires, and internal conflicts. Through internal search, the audience understands the inner side of the characters. In this process, a film director should ensure that the acting depicts the inner side of the characters. In other words, the director should perfectly depict the internal and external elements of a human on screen. Appropriate visualization can lead to dramatic communication with the characters and thereby create the audience's emotional response. Considering these techniques, this paper focuses on the scenes of the film "Poetry" in which dramatic communication with the characters creates the audience's emotional response. Accordingly, the audience plays a role in sustaining dramatic communication for the physical screen time of a film.

  • Techniques for making a single panoramic image using multiple pictures are widely studied in many areas such as computer vision, computer graphics, etc. The panorama image can be applied to various fields like virtual reality, robot vision areas which require wide-angled shots as an useful way to overcome the limitations such as picture-angle, resolutions, and internal informations of an image taken from a single camera. It is so much meaningful in a point that a panoramic image usually provides better immersion feeling than a plain image. Although there are many ways to build a panoramic image, most of them are using the way of extracting feature points and matching points of each images for making a single panoramic image. In addition, those methods use the RANSAC(RANdom SAmple Consensus) algorithm with matching points and the Homography matrix to transform the image. The SURF(Speeded Up Robust Features) algorithm which is used in this paper to extract featuring points uses an image's black and white informations and local spatial informations. The SURF is widely being used since it is very much robust at detecting image's size, view-point changes, and additionally, faster than the SIFT(Scale Invariant Features Transform) algorithm. The SURF has a shortcoming of making an error which results in decreasing the RANSAC algorithm's performance speed when extracting image's feature points. As a result, this may increase the CPU usage occupation rate. The error of detecting matching points may role as a critical reason for disqualifying panoramic image's accuracy and lucidity. In this paper, in order to minimize errors of extracting matching points, we used $3{\times}3$ region's RGB pixel values around the matching points' coordinates to perform intermediate filtering process for removing wrong matching points. We have also presented analysis and evaluation results relating to enhanced working speed for producing a panorama image, CPU usage rate, extracted matching points' decreasing rate and accuracy.

  • This paper expands the results of previous studies indicating that manager's ability positively affects business performance to analyze whether the degree to which the role of manager's ability improves business performance appears differently according to the characteristics of enterprises. As for the characteristics of enterprises, whether enterprises correspond to enterprises with high levels of funding constraints or late movers in the market is considered. Enterprises with high levels of funding constraints greatly require managers' roles not only for efficient use of funds but also for smooth financing. Late movers require more judgments of professional managers to overcome insufficient resources held and low profitability. In the case of enterprises with corporate characteristics with high dependency on the manager, the business performance is expected to greatly vary with the ability of the manager. The empirical analysis was conducted with listed companies from 2010 to 2014, manager's ability was measured by first measuring the efficiency of the entire enterprise through data envelopment analysis (DEA) using the methodology of Demerjian et al.(2012) and removing enterprise characteristics factors thereafter. Business performance was measured by the return on industrial fixed assets. The results of the empirical analysis indicated that the degree to which manager's ability improves business performance was higher in managerial competence enhances managerial performance in enterprises with high levels of funding constraints and late movers. Business performance is considered to have been improved further in cases where manager's ability is high because investments were made more efficiently through smooth funding. In addition, in the case of late movers in relatively poor environments, business performance was improved further because high manager's ability induced efficient decision making. In this paper, we extend the precedent study that the manager's ability improves the management performance, and confirm that the manager's ability to improve the managerial performance can be different according to the situation of the company. In addition, it is meaningful to analyze empirically whether a company's managerial ability is more important. This paper expanded the results of previous studies indicating that manager's ability improves performance to identify that the degree to which manager's ability improves business performance may appear differently according to situations in which enterprises are placed. In addition, this paper is meaningful in that it empirically analyzed what enterprises require manager's ability more importantly.

  • Under the market economy of capitalism, several limitations reveal the inequity and redistribution problem of wealth, inefficiency of over-manufacturing and over-consumption, pollution of the natural environment, and the constraint of human liberty and dignity. The new challenge of symbiotic relationships that encourage individual corporations coincides with the need to practice social responsibility and share values to overcome these limitations. Social economy and the social enterprises that simultaneously pursue the making of corporate private profits and the realization of social values have been suggested and disseminated as alternative social value creators. Furthermore, the concept of a sharing economy, which refers to the sharing of things rather than owning them, is growing traction as a new paradigm of capitalism. However, these efforts of social enterprises have fallen short against the conflicts between private profit and social values. This study deals with the case of a start-up social corporation, "Purun Bike Sharing Inc.," which is based on a regional sharing economy business model about bike rental services that use Information and Communication Technology (ICT). This corporation pursues harmonic management to achieve a balance between private profit and social value. Its corporate mission is to achieve sharing, coexistence, and contribution for public welfare. This mission is a possible idea for use in the local community network as a core key for sustainable social enterprises. The model can also be an alternative approach to overcome the structural friction in the social corporation. This study considers the case of Purun Bike Sharing as a sustainable way to practice a sharing economy business model based on a regional cooperation network, which can be combined with social value, and to apply ICT to a sharing economy system. It also examines the definition and current state of social enterprises and the sharing economy, and the cases of the sharing economy business model for the review of prior research.

  • This study was conducted to investigate the interaction of aflatoxin B$_1$($AFB_1$) and vitamin D$_3$($VD_3$) in broiler chicks. The 336 broiler chicks(Hubbard line) of equally mixed sex were allocated to triplicate 8(2$\times$4 factorial) treatment groups. The 0 or 1ppm of AFB$_1$and 0, 500, 1,000 or 1,500IU/kg of VD$_3$ were supplemented to the basal diet Fourteen broilers of equally mixed sex were allocated to each replica and 24 groups were arranged in a randomized block design After 3 weeks of feeding the metatarsus were collected from the right and left legs of 4 chicks (2 for each sex) per group. The bone ash and minerals were measured. 1. In respect to the fresh weight of metatarsus bone no significant difference was found between 0 and 1ppm $AFB_1$ treatments, however, decreasing trend was recognized when fed increasing level of $VD_3$(P<.01). 2. The ash content in non-fat dry metatarsus bone decreased when fed 1ppm $AFB_1$(P<.01). However, that increased according to the increasing amount of $VD_3$(P<.01). Although there was no interaction between $AFB_1$ and $VD_3$ it was shown that the 1500IU/kg of $VD_3$ was neccessary to cover the decrease in ash content of metatarsus. when fed 1ppm of $AFB_1$. 3. The Ca contents in metatarsus were not influenced by feeding $AFB_1$ but an increasing trend was verified by feeding increasing levels of $VD_3$(P<.05). 4. The P content decreased as $AFB_1$ was fed(P<.01), while no response was found when fed'different levels of $VD_3$ 5. The Cu content decreased when fed $AFB_1$(P<.05). 6. The Na, Mg, K, Zn, Fe and Mn contents were not affected by feeding $AFB_1$ and /or $VD_3$.
