  • The FRP pole had great advantages over other material poles. Light weight, easy installing and transporting were good characteristics. The material's superior properties represented the good durability for sea weather and air pollution, good insulation for electric, and changeable colors. In those properties, usages were like a area affected by sea, downtown, the area among the mountains and a special area for the outstanding views. It was studied that pole manufacturing method, structure analysis of pole by FEM in this study. Filament winding method was selected for a new pole manufacturing method. It produced the tapered poles and mechanically strong properties.

  • The purpose of this research is to provide new direction on the field of the furniture design and to establish the identity of Korean furniture design as the flow of craft's juxtapose mixture era where it mix and match Korean traditional craft style materials with the modern furniture design. In other words, it is intended to create new furniture design and propose beautiful Korean luxury furniture design based on the precious unique culture with the traditional craft style, juxtaposition of modern furniture, and reinterpretation. It should grant artistic values that can satisfy consumers having various tastes and scarcity values, plus it should put out aesthetic and creative expressions in furniture design putting into the beautiful traditional craft form values. Furthermore, it is required to create new design through values and spirit, materials, techniques, forms, pattern, and usages by interacting, coordinating, and combining tradition and modern East and West, plus craft and design.

  • The purpose of this study was: 1) to investigate whether Korean dietitians are engaged in Foodservice Systems Management (FSM) competencies in their current jobs, and 2) to identify the relationship between types of dietetic practice areas and Korean dietitians' usage of FSM competencies. Fifteen FSM competencies were widely used, 17 were somewhat used, 13 were seldom used and the remaining two competencies were little or not used by the dietitians. The most used competency was related to menu planning (98%). Whereas, the least used competency was related to marketing skills (17%). As a whole, the categories of 'technical and communication skills' (78%) and 'production and distribution management' (77%) were more widely used than other FSM categories. Of 47 competencies, 34 competencies were found to be significantly associated with the type of practice area. Considering the findings, the type of dietetic practice area was a strong factor of Korean dietitians' usages of FSM competencies. Of 34 competencies associated with the type of dietetic practice area, 25 FSM competencies were more likely to be used by the dietitians from health care facilities.

  • XKASS(XML Key Agreement Specification)는 사용자를 통해 XKMS와 연동하여 인증서 기반으로 클라이언트를 확인하고 키 동의를 하는 프로토콜이다. 기존 XKASS 에서는 공개키 암호화 기법을 사용해 키 교환을 하는 방식과 전자서명 기법을 사용해 키 교환을 하는 방식을 사용한다 기존 XKASS의 전자서명과 공개키 방식의 암호화 해독화 방법은 인증서를 그냥 전달함으로써 사용자의 신원이 노출되는 문제점이 있고, 계산 비용이 많이 든다. 본 논문에서는 기존의 XKASS 프로토콜에서 인증서 기반 공개키 암호화 방식을 사용한 키 교환 프로토콜을 사용하지 않고 키 교환 프로토콜을 수행하여 공격자에게 사용자의 신원보호를 제공하고 계산 비용을 줄인 확장된 XKASS 방식을 제안한다. 사용자에게 제한된 priority를 주는 것으로 DoS(Denial of Service) 공격을 예방한 기존의 XKASS를 확장하여 다중 영역에 사용할 수 있도록 제안하였다.

  • Medical infrared imaging is obtained by measuring the self-emitted infrared radiance from the human body. Infrared emission is related to surface temperature and temperature is one of the most important physiological parameters related to health. Though recent applications such as security identification and oriental medicine have provided new fields of biomedical applications, infrared thermography has had ups and downs in its usages in cancer detection. Some of the main difficulties include finding proper applications and efficient diagnostic algorithms. In this study, infrared thermal imaging was used to detect regional metastasis of breast cancer. Our measurements were done for 110 women. From 63 individuals of a Healthy Group and a Benign Breast Disease Group, we developed algorithms for differentiating malignant regional metastasis based on temperature difference and asymmetry of temperature distribution. Testing with 47 cancer patients, we achieved a positive predictive value of $87.5\%$ and a negative predictive value of $95.6\%$. The results were better than for mammogram examination. A proper analysis of infrared imaging proved to be a highly informative and sensitive method for differentiating regional cancer metastasis from normal regions.

  • This paper is an HPSG approach to agreement phenomena involving the Korean honorific expressions. it is shown that the theoretical devices developed by the constraint-based theory of HPSG can be fruitfully used to capture the interactions between syntactic constraints and semantic of pragmatic factors in Korean honorific agreement. The HPSG's semantic feature 'referential index' plays a key rele in discribing the multiple interaction. The constraint-based theory of agreement proves successful in accounting for the phenomenon that may be called 'inconsistent' honorific agreement as well as 'consistent' regular honorific usages. However, this paper acknowledges its limit. Recognizing an important distinction between basic and 'coercive' honorific expressions, it is argued that a systactic-semantic-pragmatic approach such as the present one can only be applied to basic honorific agreement. Being sociolinguistic in nature, coercive honorific agreement is perhaps not amenable to formal linguistic investigation.

  • In this study, we studied the changes in antioxidant activity of Actinidia arguta fruit of Autumn Sense cultivar during fruit ripening. The aim of this investigation was to find the knowledge of the changes of physiochemicals associated with fruit quality, antioxidant properties (free-radical scavenging activity and reducing power), total phenolics and vitamin C during fruit ripening. The highest free-radical scavenging activity (at $100{\mu}g/ml$) and reducing power (at $100{\mu}g/ml$) in A. arguta fruit were 78.57% and 0.22, respectively. Total phenolic content and vitamin C content in fruit of 10 days after fruit set were $639.48{\mu}g/g$ and $1052.2{\mu}g/g$, respectively. In general, the antioxidant activity and the related parameters, including total phenolic content and vitamin C content decreased during fruit ripening. These results improve knowledge of the effect of ripening on the antioxidant activity and related compounds contents that could help to establish the optimum A. arguta fruit harvest data for various usages.

  • Metadata is a structured data that makes computer to understand web based data. Types of metadata are Dublin core, ONIX, and EBKS metadata in Korea. Dublin Core is well known among these metadata. Archive is a data, that is the result of ones or groups working process, which is reasonably maintained and stored. These archives are stored and maintained lawfully and suitably for efficient usages for the future. For efficiently managing these grant amount of archive, Finding Aids and Description are needed. Adoption Archives and Records Management system is inevitable in order to maintain organized and efficient data. Metadata helps governments data that is grant to organize in simple way. For maintaining and storing data efficiently, using metadata for Archives and Records Management is essential. Form this report, we will see the examples of using metadata of other country, such as GILS(Government Information Locator Service), AGLS(The Australian Government Locator Service), NZGLS(New Zealand Government Locator Service), Danish Dublin Core and e-GMS(e-Government Metadata Standard) and e-GMF(e-Government Metadata Framework).

  • The purpose of this work is to analyze categorial character of Russian verbal aspect from the typological perspective. To do this, first of all we will examine the overall historical process of grammaticalization of Russian verbal aspect. As a result of analysis, we have suggested that against wide-spread general assumptions in this area Russian verbal aspect correspond rather to lexico-grammatical category, than to purely typical grammatical category. Actually, I think this kind of approach as a pivotal point for the study of Russian verbal aspect. For example, this kind of typological approach has great advantages in a sense that firstly it gives us possibility of breaking from notorious routine Slavic-Centrism, secondly it can explain sufficiently and adequately various lexico-semantic usages of Russian verbs. Thirdly, our approach consistently accounts for various interactions of lexico-semantic, grammatical, discourse-pragmatic levels, in which Russian verbal aspect is involved. And finally, it sheds light on functional interactions between verbal categories, such as aspect, tense, and mood.
