  • Korean government will set up the nationwide food safety system with strict control of hazardous nutrients like sugar, fatty acids and sodium as well as advanced nutrition education system. In addition, almost one hundred percent of school food service rate forced the government to consider more effective ways to upgrade the nutritional status of school meals. The object of our study was to provide the data on content and consumption of sugar in school meal for the nationwide project. For this purpose, we surveyed the sugar content of 842 school meal menus and their intake level for 154 days in 8 schools in Daejeon and Chungcheong Province. Sugar contents, the sum of the quantity of 5 sugars commonly detected in food, were analysed with HPLC-RID (Refractive Index Detector). Sugar intakes were calculated by multiplying the intake of each menu to the sugar content of that menu. The sugar content was highest in the desserts, which include fruit juices, dairy products and fruits. Sugar content of side dish was high in sauces and braised foods. Sugar intake from one dish is high in beverage and dairy product, and one dish meals contribute greatly to sugar intake because of their large amount of meal intake. The average lunch meal intakes of second grade and fifth grade elementary school students were 244 g/meal and 304 g/meal, respectively. The meal intake of middle school student was 401 g/meal. The average sugar intake from one day school lunch was 4.22 g (4.03 g on elementary and 5.31 g on middle school student), which is less than 10% of daily sugar reference value for Koreans. The result of this study provides exact data of sugar intake pattern based on the content of sugar which is matched directly to the meals consumed by the students.

  • The UET(ultrasound excited thermography) for the ,eat-time diagnostics of the object employs an infrared camera to image defects of the surface and subsurface which are locally heated using high-frequency putted ultrasonic excitation. The dissipation of high-power ultrasonic energy around the feces of the defects causes an increase In temperature. The defect's image appears as a hot spot (bright IR source) within a dark background field. The UET for nondestructive diagnostic and evaluation is based on the image analysis of the hot spot as a local response to ultrasonic excited heat deposition. In this paper the applicability of VET for fast imaging of defect is described. The ultrasonic energy is injected into the sample through a transducer in the vertical and horizontal directions respectively. The voltage applied to the transducer is measured by digital oscilloscope, and the waveform are compared. Measurements were performed on four kinds of materials: SUS fatigue crack specimen(thickness 14mm), PCB plate(1.8 mm), CFRP plate(3 mm) and Inconel 600 plate (1 mm). A high power ultrasonic energy with pulse durations of 250ms Is injected into the samples in the horizontal and vertical directions respectively The obtained experimental result reveals that the dissipation loss of the ultrasonic energy In the vertical injection is less than that in the horizontal direction. In the cafe or PCB, CFRP, the size of hot spot in the vortical injection if larger than that in horizontal direction. Duration time of the hot spot in the vertical direction is three times as long as that in the horizontal direction. In the case of Inconel 600 plate and SUS sample, the hot spot in the horizontal injection was detected faster than that in the vertical direction

  • The purpose of this study is to develop a neuropsychological model for the spatial ability factor and to divide the brain active area involved in the light & shadow problem solving process into the domain-general ability and the domain-specific ability based on the neuropsychological model. Twenty-four male college students participated in the study to measure the synchronized eye movement and electroencephalograms (EEG) while they performed the spatial ability test and the light & shadow tasks. Neuropsychological model for the spatial ability factor and light & shadow problem solving process was developed by integrating the measurements of the participants' eye movements, brain activity areas, and the interview findings regarding their thoughts and strategies. The results of this study are as follows; first, the spatial visualization and mental rotation factors mainly required activation of the parietal lobe, and the spatial orientation factor required activation of the frontal lobe. Second, in the light & shadow problem solving process, participants use both their spatial ability as a domain-general thought, and the application of scientific principles as a domain-specific thought. The brain activity patterns resulting from a participants' inferring the shadow by parallel light source and inferring the shadow when the direction of the light changed were similar to the neuropsychological model for the spatial visualization factor. The brain activity pattern from inferring an object from its shadow by light from multiple directions was similar to the neuropsychological model for the spatial orientation factor. The brain activity pattern from inferring a shadow with a point source of light was similar to the neuropsychological model for the spatial visualization factor. In addition, when solving the light & shadow tasks, the brain's middle temporal gyrus, precentral gyrus, inferior frontal gyrus, middle frontal gyrus were additionally activated, which are responsible for deductive reasoning, working memory, and planning for action.

  • The purpose of this paper is to interpret the discourse on design thinking through the perspective of Roland Barthes' Mythologies. To this end, this paper will explore the mythologization process of design thinking using the methodological framework of Barthes, which structurally interprets the connotations produced using semiosis. Design thinking originally refers to a method which is used in the process of planning ideas about designs in order to create the final products for professional designs. However, design thinking has recently attracted more interest from the public because it has become known as a tool for solving various problems which exist outside of the field of design, such as social issues, management, and marketing strategies. Barthes points out that myths are used as a tool to deliver ideologies. He also emphasizes the importance of 'structural thinking'. It interprets the inherent connotative meanings more than the denotative meanings, which are explicitly shown. One of the most powerful ideologies which our society embraces today is creativity. Design thinking realizes the manifestation of creativity through a schematized process. This can be explained by considering design thinking as an icon that is specifically turned into a figuration to realize its objectness, in which a discourse for solving issues and social codes meet together and form a mythology. The mythologies that Barthes cites in his book refer to mythical values created by the cultural codes which humans have produced in our modern and contemporary age. The symbolic value of design thinking has become more important than the signifier which design thinking itself presents. This means that design thinking has become a sign that has mythical properties. In other words, the ideology of creativity embodied by design thinking has attained a mythological status, as it produces a new cultural code through innovation. The process of interpreting a phenomenon using the perspective of semiotics is an important tool that allows us to examine the concept of an object and its surroundings thoroughly. This paper attempts to expand the external scope of critical analysis about social phenomena by using the signs which continuously reveal themselves in common ideologies, such as design thinking, which has been gaining more popularity recently.

  • This essay examines the ego (I-Subject) problem in Husserl's phenomenology and consists of four parts, as follows. Section I describes the meaning of this research on ego and some important points to note in relation to this study. Section II discusses two aspects of the problem of pure ego, which appears as an ego-problem for the first time. The first aspect is the two opposing positions that Husserl himself took regarding pure ego. Husserl initially rejected pure ego as an object of research in Logische Untersuchungen I (1901) however, he withdrew this position in Logische Untersuchungen II (1913). The second aspect is the content of pure ego that Husserl explored in Ideen I (1913) after he accepted pure ego as a phenomenological problem. The theme of section III is the "theory of three egos" which appeared in Ideen II (1912, 1952). Here, two issues have been noted, one of which is the methodological basis for enabling this theory: the phenomenological "attitude change" (Einstellungsaenderung) and the "Underlying" (Fundierung). The other is the explanation of the content of the three egos: the "physical ego", "personal ego" and the "pure ego". Section IV concerns two themes of the "monadic ego" that appeared in the Cartesianische Meditationen (1931). The first theme is the theoretical premise for the establishment of the monadic ego. In conjunction with this theme, phenomenological-psychological reduction was used as a new method to open up new problem horizons. The second theme brings up the content of the monadic ego, the essence of which can be summarized as follows. 1) This ego is based on a pluralistic and independent ego-concept in which each ego is equal to its own self. 2) It must be asked whether each of the monadic egos is different from one another. 3) The "other" of a certain transcendental ego is not the ego-other relationship but ego-another ego (alter-ego). 4) This phenomenological monadic ego can mutually communicate with alter-egos through empathy, unlike Leibniz's metaphysical monads.

Investigation on Cognition and Ego in Kant, Husserl and Yogācāra - focused on trisvabhāva and the transformation of the basis of mind in Yogācāra - (칸트, 후설과 유식철학(唯識哲學)에서 인식과 자아 문제에 관한 연구 - 유식철학(唯識哲學)의 삼성설(三性說)과 전식득지(轉識得智)를 중심으로 -)

  • In this paper I will investigate the problems of the Ego of Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$ from the standpoint of $trisvabh{\bar{a}}va$ and the transformation of the basis of $Yog{\bar{a}}c{\bar{a}}ra$. Kant's Copernican revolution and Husserl's Phenomenological reduction are the keys to understanding their philosophies. We especially want to look into the comparison between the Ego of Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$. According to Kant, we need the transcendental Ego as absolute in order to unite consciousness. Kant criticizes traditional metaphysics which had argued that the metaphysicians regard the transcendental Ego as substance. If they regard the transcendental Ego as an empirical object, this attempt will be in vain, because they seek to know unknown things. Husserl's phenomenological reduction is properly understood as a method designed to transform a philosopher into a phenomenologist by virtue of the attainment of a certain perspective on the world phenomenon. We will find the field of the transcendental, absolute ego through phenomenological reduction. Transcendental, absolute ego constitutes our whole world and gives meaning to the world. $Yog{\bar{a}}c{\bar{a}}ra$ argues that what our ordinary consciousness (the sixth consciousness) regards subjectivity and objectivity as separate, or that self and the world is an imagination that $alaya-vij{\tilde{n}}ana$, the mind more profound than the ordinary consciousness, created. $Yog{\bar{a}}c{\bar{a}}ra^{\prime}s$ $alaya-vij{\tilde{n}}ana$ creates the whole objects and the consciousness (the sixth), so we must regard them as illusionary. $Yog{\bar{a}}c{\bar{a}}ra$ insists that there are three natures of mind and we attain the transformation of the basis in mind. Based on this point of view, Kant, Husserl and $Yog{\bar{a}}c{\bar{a}}ra$ want to transcend and overcome the limits of the ordinary consciousness, and then they want to find the absolute truth (everything) and want to be a men of freedom.

  • The purpose of this study was to examine the characteristics of Seoul Olympic Organizing Committee's official documents. To conduct this work, the fundamental of producing archives were examined by analyzing structure and management of Seoul Olympic Organizing Committee and structure of official document production. After all, simultaneous and synthesis characteristics of Seoul Olympic Organizing Committee's official documents were presented through overall analysis of production fundamental and relationship between their management and remained archives. The result of this study are as follows. Firstly, The Organizing Committee had bicameral organizational structure and matrix organizational format consisting of functional department and project department. Indicating the institutions and development phase of decision making in the committee, most of institutions were in name only. Also, there were many problems occurred in the procedure of decision making since the president of committee exercised all of the authorities. Secondly, It was found that existing official documents of the committee were partial and caused fragment phenomenon and severe situations because of unsystematic archival management department and regulations. Moreover, as the result of investigating production procedure and management of official documents, procedure of production, distribution, preservation and abolition of them were specifically verified. Thirdly, It was verified that the official documents were abolished arbitrarily because of unsystematic archival management department and insufficient regulations. For the actual condition of management, filing or description activity which is essential measure for using and utilizing the official documents has not been conducted yet. Based on these facts, the characteristics of Seoul Olympic Organizing Committee's official documents can be referred as follows. The official archives of the committee have multiplicity of the origin and severe fragment phenomenon damaging the origin and the elementary substance of the archives. Also, the format of existing archives was unbalance. Besides, there was not enough related research since they were in adverse situation to utilize them as the archives which are not assessed or not arranged. Thus, it was hard to grasp the utility value at present and future, and was also limited for usage object.

  • Artificial or natural artifacts, which have historical, artistic, academic or scenic value as national, ethnic or global assets, are designated as "cultural heritages" under the Act on the Protection of Cultural Heritage. Cultural heritages can be divided into tangible cultural heritages, intangible cultural heritages, and monument and folklore heritages. In addition, depending on the object of designation, a cultural heritage can be designated either as a city or a provincial cultural heritage or a cultural heritage material, by a city mayor or provincial governor, and as a state-designated heritage by the administrator of the Cultural heritage Administration. The regular survey is a part of the policy for the preservation and management of state-designated heritages, which requires that surveys be undertaken every three to five years for the preservation, repair and maintenance of cultural heritages. It was stipulated in the Act on the Protection of Cultural Heritage in 2006, and since then has substantially contributed to the preservation and management of state-designated heritages based on the identification of damage to cultural heritages and the application of appropriate treatment measures. However, some parts of the guidelines on the regular survey, legislated in 2006, occasionally give rise to confusion in managing the regular survey system of state-designated movable cultural heritages, and need to be modified to facilitate the systematic management and improvement of the regular survey system. This study attempts to analyze the structure and operation of the regular survey system of state-designated movable cultural heritages, and proposes plans for improving the way of specifying each department which leads, manages and executes the regular survey, the process of entrusting the survey, and its guidelines and forms. I hope that these plans concerning the regular survey of state-designated movable cultural heritages will contribute to improving the quality and management of the system.
