The aim of this study is to investigate college students' opinion on participation in media education. The research question is as follows: first, what is the college students' perceptions who participated in media education? Second, what are the differences among the perceptions of college students who participated in media education? To answer these research questions, we used Q-methodology, which is more useful in organizing subjectivity types and opinions of students, both in explaining and sorting of data by characteristic and personal opinion. As a result, two types were found; type 1 is the active participation type that focuses on the active participation in media education as a productive tool and teaching method, as well as diminishing the current controls and restrictions on its use in education. On the other hand, type 2 is the growing adaptive type and is positive for the future development of media education in a transitional role, while they think that current media education for college students is not qualitative yet, a productive tool and the quality of the information message is lacking, and so on.

In an attempt to measure the needs of sexuality education according to sex. grade. type of school. this study was carried out. For this study, the questionnaires were given to 600 students of 4 high-schools in Seoul from March to April. 1999. Students never being received sexuality education were 32.5%. Even though in students being received sex education, the answer of being very instructive was only 2.2%. The needs of sexuality education in boy-student was high in sexual behavior and relationship domain as compared with the girl-student, especially high in masturbation and sexual dysfunction. In girl-student, the needs of sexuality education were high in abortion. sexual damage. In third-grade, the needs of sexuality education were high in personal skill domain as compared with the first and second-grade. And the second-grade's needs were high in sexual behavior domain. In academic school students, the needs of sexuality education were high in sexual behavior and sexual health domain as compared with vocational school. In conclusion, a variety of systematic sex education programs suitable for each characteristic of adolescence should be in need of being developed to the base on the sex educational needs of the students.

This paper proposes an interpretation of Charles Ess's pros hen pluralism, especially concerning what constitutes the single end point (hen) toward which the pluralistic viewpoints converge (pros). The single end point, I argue, is constituted by an empirical social reality that obtains in the world at a particular period. In other words, it is the fact that we happen to agree largely and broadly on several ethical issues that serves as the end point in Ess's theory. The reason is that humans happen largely to share the same goals and values qua human beings, such as the desire for communication and cooperation with one another. It is not their rationality, or any other permanent and ideal characteristic, that serves as the source of normativity for human beings, but rather the contingent facts that obtain at a particular place and time, facts that humans happen to agree on. This raises an obvious objection of what to do with those who might cherish a very different set of values. The answer is that the globalized nature of the world today, especially deepened by information technology, makes it increasingly difficult for any groups to remain isolated. This does not imply, however, that disagreements are not possible. On the contrary, disagreements are a part of the whole process from the beginning. At the theoretical level, there is always a need for those who disagree on the theoretical issues rationally to persuade one another. This is also part of the empirical reality referred to earlier.

Let K be a field of characteristic zero. We first show that images of the linear derivations and the linear 𝓔-derivations of the polynomial algebra K[x] = K[x₁, x₂, …, x_n] are ideals if the products of any power of eigenvalues of the matrices according to the linear derivations and the linear 𝓔-derivations are not unity. In addition, we prove that the images of D and 𝛿 are Mathieu-Zhao spaces of the polynomial algebra K[x] if D = ∑ⁿ_i=1 (a_ix_i + b_i)∂_i and 𝛿 = I - 𝜙, 𝜙(x_i) = λ_ix_i + 𝜇_i for a_i, b_i, λ_i, 𝜇_i ∈ K for 1 ≤ i ≤ n. Finally, we prove that the image of an affine 𝓔-derivation of the polynomial algebra K[x₁, x₂] is a Mathieu-Zhao space of the polynomial algebra K[x₁, x₂]. Hence we give an affirmative answer to the LFED Conjecture for the affine 𝓔-derivations of the polynomial algebra K[x₁, x₂].

In this paper, we propose a methodology to extract answer information about queries from various types of unstructured documents collected from multi-sources existing on web in order to expand knowledge base. The proposed methodology is divided into the following steps. 1) Collect relevant documents from Wikipedia, Naver encyclopedia, and Naver news sources for "subject-predicate" separated queries and classify the proper documents. 2) Determine whether the sentence is suitable for extracting information and derive the confidence. 3) Based on the predicate feature, extract the information in the proper sentence and derive the overall confidence of the information extraction result. In order to evaluate the performance of the information extraction system, we selected 400 queries from the artificial intelligence speaker of SK-Telecom. Compared with the baseline model, it is confirmed that it shows higher performance index than the existing model. The contribution of this study is that we develop a sequence tagging model based on bi-directional LSTM-CRF using the predicate feature of the query, with this we developed a robust model that can maintain high recall performance even in various types of unstructured documents collected from multiple sources. The problem of information extraction for knowledge base extension should take into account heterogeneous characteristics of source-specific document types. The proposed methodology proved to extract information effectively from various types of unstructured documents compared to the baseline model. There is a limitation in previous research that the performance is poor when extracting information about the document type that is different from the training data. In addition, this study can prevent unnecessary information extraction attempts from the documents that do not include the answer information through the process for predicting the suitability of information extraction of documents and sentences before the information extraction step. It is meaningful that we provided a method that precision performance can be maintained even in actual web environment. The information extraction problem for the knowledge base expansion has the characteristic that it can not guarantee whether the document includes the correct answer because it is aimed at the unstructured document existing in the real web. When the question answering is performed on a real web, previous machine reading comprehension studies has a limitation that it shows a low level of precision because it frequently attempts to extract an answer even in a document in which there is no correct answer. The policy that predicts the suitability of document and sentence information extraction is meaningful in that it contributes to maintaining the performance of information extraction even in real web environment. The limitations of this study and future research directions are as follows. First, it is a problem related to data preprocessing. In this study, the unit of knowledge extraction is classified through the morphological analysis based on the open source Konlpy python package, and the information extraction result can be improperly performed because morphological analysis is not performed properly. To enhance the performance of information extraction results, it is necessary to develop an advanced morpheme analyzer. Second, it is a problem of entity ambiguity. The information extraction system of this study can not distinguish the same name that has different intention. If several people with the same name appear in the news, the system may not extract information about the intended query. In future research, it is necessary to take measures to identify the person with the same name. Third, it is a problem of evaluation query data. In this study, we selected 400 of user queries collected from SK Telecom 's interactive artificial intelligent speaker to evaluate the performance of the information extraction system. n this study, we developed evaluation data set using 800 documents (400 questions * 7 articles per question (1 Wikipedia, 3 Naver encyclopedia, 3 Naver news) by judging whether a correct answer is included or not. To ensure the external validity of the study, it is desirable to use more queries to determine the performance of the system. This is a costly activity that must be done manually. Future research needs to evaluate the system for more queries. It is also necessary to develop a Korean benchmark data set of information extraction system for queries from multi-source web documents to build an environment that can evaluate the results more objectively.

This paper is an essay on Chaekmun(Answer papers of official examination in Pre-modern period). Especially I tried to point out the possibility of practical use in the field of politics. For this purpose, I analyzed an examination paper written by Lee Ga-hwan, and the title is "a debate about construction of the Miang palace". Exquisite writing skill is also important in Chaekmun, but it is not everything. The subject of Chaekmun concerns various fields such like politics, economy, society, culture, and history. So that writers should have sufficient knowledge and opinion. The King, as an examiner, wants to test retainers' ability both in writing and politics. In this paper, I focused on using in field of politics between the King and the retainers. And as an good example, I analyzed a paper which dealt the event of building huge palace named Miang palace. That is because the King reflects his concerns by setting exam questions. And his concerns also could not be free of contemporary political conditions. Therefore we should be careful of reading those articles. Regarding this, Lee Ga-hwan's article had a distinctive characteristic. Unlike any other articles dealing with same event, he tried to access through creative point of view. And his thought were much close to the King's heart.

This study examines the universal meaning of the roof-end tile, our cultural property, and especially focuses on an ontological interpretation of the "Smile of Silla" roof-end tile. In addition, the problem of good and evil read here is considered in connection with the universal problem of philosophy. The issue of good and evil is a theme in philosophy, theology, religion, and culture that will endure throughout human history in both the East and the West. Augustine and Schelling inquired deeply into the source of evil and obtained an answer to this question based on their methods, but their answer is not universal or absolute, or an answer that applies to everyone. This is because the issue of good and evil possesses both a direct relationship with every human being and a characteristic that will remain unresolved. That is to say, the metaphysical question regarding the source of evil will always be one that is open. Nietzsche, however, repudiated the morals handed down through Socrates and Christianity, and urged that we reside "beyond good and evil." This brief review argues that good and evil exists in the form of a being in itself, whether it is within our grasp or not, and reveals that good and evil is more "this-worldly" than it is "other-worldly". The roof-end tiles with facial markings passed on to us also presuppose that evil is in full force in this world and exerts its influence. This review taps into several folk methods for coping with the existence of an invincible evil that surpasses human capability and contemplates the extraordinary and creative ideas of the Silla people through their "Smile of Silla" roof-end tiles with facial markings that were used to counter evil.

Quite recently, it has been suggested that the interaction of the solar wind with Mercury results in the variation in the solar wind velocity in the Earth's neighborhood during inferior conjunctions with Mercury. This suggestion has important implications both on the plasma physics of the interplanetary space and on the space weather forecast. In this study we have attempted to answer a question of whether the claim is properly tested. We confirm that there are indeed ups and downs in the profile of the solar wind velocity measured at the distance of 1 AU from the Sun. However, the characteristic attribute of the variation in the solar wind velocity during the inferior conjunctions with Mercury is found to be insensitive to the phase of the solar cycles, contrary to an earlier suggestion. We have found that the cases of the superior conjunctions with Mercury and of even randomly chosen data sets rather result in similar features. Cases of Venus are also examined, where it is found that the ups and downs with a period of ~ 10 to 15 days can be also seen. We conclude, therefore, that those variations in the solar wind velocity turn out to be a part of random fluctuations and have nothing to do with the relative position of inner planets. At least, one should conclude that the solar wind velocity is not a proper observable modulated by inner planets at the distance of 1 AU from the Sun in the Earth's neighborhood during inferior conjunctions.

"본 논문은 대한외과학회지 2006년 제70권제1호에 실렸던 논문으로 대한외과학회 편집위원회 승인을 득하고 본 협회지에 게재함. Purpose: Malnutrition has been frequently reported for patients on their admission to the hospital and it has been associated with an increase in morbidity, mortality and the length of the hospital stay. Although a number of screening tools have been developed to identify those patients at risk for malnutrition, there is no' gold standard' for defining malnutrition and the malnourished patients remain largely unrecognized. The aim of this study is to evaluate the efficacy of a nutritional screening tool for use in Dankook University Hospital. Methods Nutritional evaluation was performed for 53 patients who were admitted to the department of surgery and internal medicine between October and December 2004. The screening tool was completed by the ward nurse and the nutritional support team nurse on the same patients within24 hours of admission. The nutritional support team nurse performed the full assessment. The screening sheet included 4 questions regarding body mass index, recent unintentional weight loss, food intake and disease severity. Each answer was scored and a total of 5 was tested as the criterion fey malnutrition. The full assessment included current body weight, recent weight loss, triceps skinfold thickness, mid-arm muscle circumference, serum albumin)in and total lymphocyte count. Malnutrition was defined by 3 or more values below the reference values. The reliability of the screening tool was assessed using kappa statistic. Sensitivity, specificity and accuracy were calculated to evaluate the validity of the screening tool. The receiver operating characteristic(ROC) curve was drawn to choose a cutoff valve that maximizes sensitivity and specificity. Results' The level of agreement between the ward nurse and the NST nurse was good for BMI and food intake and moderate for weight loss and disease severity. The full assessment identified7 patients(13.2%) as malnourished. The screening sheet had a sensitivity of 86% and a specificity of 80%. According to the ROC curve, a score of 5 points provided the best validity. Conclusion The nutritional screening tool is reliable when completed by different observers and it is valid for nutritional assessment.
