This study focuses on a review of Hangeul orthography guidelines in Korean language regulations. It is indispensable to revise the guidelines thoroughly because it has been more than 80 years since a unified plan of Korean orthography was established in 1933, which the current orthography is based on. Also, it has been approximately 30 years since 1989, when the current guidelines were issued and promulgated. The viewpoint towards this review reflects the requirements by education fields of Korean as a foreign language and modern Korean users. Hangeul orthography consists of six clauses, along with an appendix regarding punctuation marks: 1) general rules, 2) consonants and vowels, 3) related to sounds, 4) about forms, 5) spacing between words, and 6) miscellaneous. This paper examined individual clauses and specific usages of the clauses, in terms of Korean as a foreign language. Based on the review, this paper suggests the following tasks in order to establish a draft of Hangeul orthography for foreigners. A. Among the individual clauses, some clauses that embody vocabulary education aspects should be addressed in a Korean dictionary, and deleted in Hangeul orthography guidelines. B. The clauses of Hangeul orthography guidelines should be edited for revision and substitution where necessary. C. The usage of individual clauses should be replaced with more appropriate examples aligned with everyday conversation. D. In order to establish 'Hangeul orthography for foreigners', linguists should continuously review several chapters and the appendix of Hangeul orthography, such as components about forms, spacing between words, miscellaneous, and punctuation marks. The purpose of this review is to pursue the simplicity of Hangeul orthography guidelines and the practicality in terms of reflecting more realistic examples. This review contributes to facilitate Korean language usage not only for non-native learners, but also native users.

This study analyzes convention tourism destination brand slogans focusing on the international convention cities. Data were collected from official tourism web sites of 190 cities which hosts more than ten international meetings in 2013. One hundred and six destination brand slogans were identified. Specifically, the researchers attempt to carry out content analysis of the linguistic and visual expressions of the slogans. Results indicated that in terms of linguistic expressions, most of slogans adopted word or phrase patterns pursuing brevity. In the brand slogan spectrum, nearly half of slogans are common type which didn't express destinations' specific attributes and benefits properly. And the most frequently used key words in the slogans are 'visit' and 'city'. While in terms of visual expressions, about 70% of slogans adopted typography for explicitness and 60% of them utilized human and natural resources as visual signs for building up unique images. Based on the results, implications for creating effective convention tourism destination brand slogans were also discussed.

고분자막에 의한 기체분리는 심냉분리법, 흡수법, 흡착법등에 비하여 에너지가 절약되며 장치가 간결하고 운전비용이 낮은 이점 때문에 여러가지 기체혼합물에 대하여 여러가지 목적으로 응용되기에 이르렀다. O$_{2}$/N$_{2}$ 분리막으로 요구되는 기본특성은 1) 높은 O$_{2}$ 투과성 2) 높은 O$_{2}$ 선택성 3) 막 형성에 충분한 기계적 강도 4) 열, 화학적으로 안정성이 있어야 한다. 그런데 투과계수 P$_{O_(2)}$와 투과선택도 P$_{O_(2)}$/P$_{N_(2)}$ 관계 Fig.2 에서 보는 바와 샅이 대체로 투과선택성은 상반관계에 있어서 polyimide는 높은 선택성을 나타내고 기계적 강도가 좋고 높은 열에 대하여 안정하기 때문에 일단 막재료로 양호한 조건을 갖추고 있으나 투과계수가 크지 않아 선택도를 크게 감소시키지 않으면서 투과계수를 향성시키려는 노력이 경주되고 있다. 따라서 polyimide의 화학구조와 투과계수, 투과선택도의 관계를 고찰하는 것은 대단히 중요하다. 특히 최근에는 polyimide의 화학구조를 계통적으로 변화 시켜가면서 구조와 투과특성을 고찰한 연구가 많으며, 이러한 연구를 총망라하여 화학구조와 투과특성을 고찰한 훌륭한 총설들이 발표되어왔다. Fig.3에는 지금까지 연구된 중요한 polyimide를 형성하는 dianhydride와 diamine의 구조식을 표시하였으며 이들 구조의 변화에 의하여 기체투과계수와 투과선택도가 어떤 영향을 받는지 고찰하고자 한다.

The purpose of this thesis is to suggest objective basic data for the environmental design through the quantitative analysis of the visual quality included in the physical environment of forest landscape. For this, landscape values of forest landscape have been evaluated by using the Iverson method, the images structure of forest landscape's main utilizing space have been analysed by the factor analysis algorithm, degree of visual preferences have been pleasured mainly by questionnaries and SBE method, and finally these thesis can be summarized as fallow LCP with high values of Iverson factors I and IV yield high landscape value. Specifically, Iverson factor IV has been found to play the dominant. For all experimental points, significant seasonal variations in S.D. scale values have been observed. In natural parks, where artificial structures are complementary to the natural landscape, main factors of image are S.D. scales such as the visual sequence, the formal simplicity of structures, the emphasis, the unification of heterogeneous factors and the assimilation. Factors covering the spatial image of natural parks have been found to be the overall evaluation, the individual characteristics, the tidiness, the potentiality, the dignity, the intimacy and the space volume. For all seasons, factors such as the individual characteristics, the dignity, the tidiness, the potentiality, yield high factor scores. As for factors determining the degree of visual preference, variables such as the summit, the skyline, rocks, the water and the degree of natural destruction by artificial structures yield high values for all seasons.

오늘날의 1세대 구매 에이전트는 상품의 전체 특징 변수(attribute)에 대해서보다는 주로 판매자들이 제시한 가격만 비교해서 구매 행위를 대행해 주고 있으며, 간혹 가격 이외의 변수에 대해 비교를 해주는 에이전트의 경우에도 협상(negotiation) 과정에서 전체 변수를 적절히 고려해주는 협상 모델은 찾아보기 힘들다. 따라서, 전자 상거래의 협상 모델(negotiation model)을 가격 변수뿐만 아니라 상품의 전체 변수로 확장시켜 주는 것이 절실히 요구되고 있다. 또한 수많은 전자상거래 업체가 나타남에 여러 도메인간 에이전트 이동 기술과 도메인의 상품 특성에 따른 협상을 진행하는 적응적 에이전트의 필요성이 요구된다. 본 논문에서는 유틸리티(utility)이론과 간결한 휴리스틱스(simple heuristics)에 바탕을 두어서 가격, 상품의 특성, 보장 기간, 서비스 정책 등에 대해서 협상을 벌이는 다중변수 에이전트 협상 프레임워크인 Pmart를 제시하고 이를 확장하여 다중 도메인에서 에이전트의 이동성을 보장하고, 각 도메인의 협상 특수 지식을 XML로 제공받아 적응성을 가지는 적응적 구매 에이전트를 제안한다.

Recently, as the demand for big data analysis increases, cases of analyzing unstructured data and using the results are also increasing. Among the various types of unstructured data, text is used as a means of communicating information in almost all fields. In addition, many analysts are interested in the amount of data is very large and relatively easy to collect compared to other unstructured and structured data. Among the various text analysis applications, document classification which classifies documents into predetermined categories, topic modeling which extracts major topics from a large number of documents, sentimental analysis or opinion mining that identifies emotions or opinions contained in texts, and Text Summarization which summarize the main contents from one document or several documents have been actively studied. Especially, the text summarization technique is actively applied in the business through the news summary service, the privacy policy summary service, ect. In addition, much research has been done in academia in accordance with the extraction approach which provides the main elements of the document selectively and the abstraction approach which extracts the elements of the document and composes new sentences by combining them. However, the technique of evaluating the quality of automatically summarized documents has not made much progress compared to the technique of automatic text summarization. Most of existing studies dealing with the quality evaluation of summarization were carried out manual summarization of document, using them as reference documents, and measuring the similarity between the automatic summary and reference document. Specifically, automatic summarization is performed through various techniques from full text, and comparison with reference document, which is an ideal summary document, is performed for measuring the quality of automatic summarization. Reference documents are provided in two major ways, the most common way is manual summarization, in which a person creates an ideal summary by hand. Since this method requires human intervention in the process of preparing the summary, it takes a lot of time and cost to write the summary, and there is a limitation that the evaluation result may be different depending on the subject of the summarizer. Therefore, in order to overcome these limitations, attempts have been made to measure the quality of summary documents without human intervention. On the other hand, as a representative attempt to overcome these limitations, a method has been recently devised to reduce the size of the full text and to measure the similarity of the reduced full text and the automatic summary. In this method, the more frequent term in the full text appears in the summary, the better the quality of the summary. However, since summarization essentially means minimizing a lot of content while minimizing content omissions, it is unreasonable to say that a "good summary" based on only frequency always means a "good summary" in its essential meaning. In order to overcome the limitations of this previous study of summarization evaluation, this study proposes an automatic quality evaluation for text summarization method based on the essential meaning of summarization. Specifically, the concept of succinctness is defined as an element indicating how few duplicated contents among the sentences of the summary, and completeness is defined as an element that indicating how few of the contents are not included in the summary. In this paper, we propose a method for automatic quality evaluation of text summarization based on the concepts of succinctness and completeness. In order to evaluate the practical applicability of the proposed methodology, 29,671 sentences were extracted from TripAdvisor 's hotel reviews, summarized the reviews by each hotel and presented the results of the experiments conducted on evaluation of the quality of summaries in accordance to the proposed methodology. It also provides a way to integrate the completeness and succinctness in the trade-off relationship into the F-Score, and propose a method to perform the optimal summarization by changing the threshold of the sentence similarity.
