This paper aims to extract an ObjectProperty-UsageMethod relation, in particular the HerbalMedicinalProperty-UsageMethod relation of the herb-plant object, as a semantic relation between two related sets, a herbal-medicinal-property concept set and a usage-method concept set from several web documents. This HerbalMedicinalProperty-UsageMethod relation benefits people by providing an alternative treatment/solution knowledge to health problems. The research includes three main problems: how to determine EDU (where EDU is an elementary discourse unit or a simple sentence/clause) with a medicinal-property/usage-method concept; how to determine the usage-method boundary; and how to determine the HerbalMedicinalProperty-UsageMethod relation between the two related sets. We propose using N-Word-Co on the verb phrase with the medicinal-property/usage-method concept to solve the first and second problems where the N-Word-Co size is determined by the learning of maximum entropy, support vector machine, and naïve Bayes. We also apply naïve Bayes to solve the third problem of determining the HerbalMedicinalProperty-UsageMethod relation with N-Word-Co elements as features. The research results can provide high precision in the HerbalMedicinalProperty-UsageMethod relation extraction.

It is the purpose of this study that propose design process of building in residential district con-sidering preferences of design concept determinants. The procedure of this study is as follows : First, classifying concept determinants and then investigate the preference of concept determinants according to the use of building in residential district. It will be proposed the process of design concept determinants through such preferences. And We will investigate applicable steps for constructing an elementary school in land development district, in order to verify these process of architectural design. It was investigated paper-survey and case studies, made up questionnaires twice. In the results, we could verify that design process considering the preference of concept determinants in residential district. These results can help designers to design appropriately, according to building usage in residential district.

Objectives The purpose of this study is to understand the influence of Daesihog-tang on Taeeum-in's patholoy and prescription in "Donguisusebowon" of Sasang Constitutional Medicine. Methods The pathologic condition in which Daesihog-tang used and the relevant herbs and prescriptions in "Sanghanron", "Donguibogam", "Dongmuyoogo haedong", "Chobongwon", and "Donguisusebowon". Results and Conclusions 1. Daesiho-tang in "Sanghanron" was used to the symptom of Yangmyung disease merging with Soyang disease. In "Donguibogam", its indications were mainly used to the severe fever-symptom of Yangmyung disease and expanded to Onbyeong and so on. 2. The concept of Daesiho-tang in "Donguibogam" was changed into Hwanggeumdaehwang-tang in "Chobongwon", which can be used to treat Onbyeong with heat-dysenteric diarrhea, and severe fever of Taeeum-in. 3. The notion of combination between Daehwang and hwanggeum used in "Dongmuyoogo haedong" and "Chobongwon" was connected to Chungmongsukgondamhwan or Jogakhwanggeumdaehwang-tang in "Chobongwon". Especially, Jogakhwanggeumdaehwang-tang for Yeokkigammo and severe constipation was formed while the concept of Onbyeong in Hwanggeumdaehwang-tang' merged with the usage of Jogak and Daehwang or Yisunggugo-hwan. 4. Jogakhwanggeumdaehwang-tang influenced on the usage of Jogakdaehwang-tang for Yangdok and Onbyeong, while the usage of Chungmongsukgondamhwan was not found in "Donguisusebowon". 5. As a result, Daesiho-tang may be presented without usages for a specific patholoy in "Donguisusebowon" because it indirectly influenced on the concept of Yangdok and Onbyeong of Taeeum-in, and the formation of Jogakdaehwang-tang in "Donguisusebowon".

Many closed schools of about more 3,000(2006 year) have occurred all over the country according to governmental policy of 1982. These closed schools were sold or rent to institution, local government, and a private, and are used by various usage such as novitiate, institution, educational facility, art creation facilities, warehouse, and factory. But, unimproved closed school facilities are still reaching for about 450. Among practical use example of such closed school, alternative educational facility, practice facilities, art creation facilities etc. with closed schools which have general surrounding natural landscape and environment uses well preserved were applied consciousness and the practice about environmental problem to ecological concept. Also, a lot of discussions about ecological concept and study for desirable solutions about practical use of closed schools example have been achieved. However, it is hard to find various ecological practical use examples at filed. In such background, this research wishes to investigate changing space and facilities variously and its usage which is applied ecological concept with regional closed schools.

In a continuously expanding wireless world, the number of radio systems increases every day and efficient spectrum usage becomes a more significant requirement. Ultra-wideband (UWB) and cognitive radio are two exciting technologies that offer new approaches to the spectrum usage. The main objective of this paper is to shed the first light on the marriage of these two important approaches. The strength of orthogonal frequency division multiplexing (OFDM) based UWB in co-existing with licensed systems is investigated. The opportunity concept is defined, and the requirements of the opportunistic spectrum usage are explained. It is proposed to take the UWB-OFDM from the current underlay implementation, and evolve it to a combined underlay and opportunistic spectrum usage technology, leading to cognitive UWB-OFDM. This way, we aim at making UWB more competitive in the wireless market with extended range, higher capacity, better performance, and a wide variety of applications.

The concept causing all the fuss is "the utility computing or the usage-based IT service", which now represents the future for IT asset in all aspects of the way they work in business, the commercial and public sector. The core of "utility computing or usage-based IT service" is changing the IT assert from "ownership" to "borrowing", which enables managers to get greater utilization of data-centre resources at lower operating costs. This trend is spreaded in public sector centering the Governmental Internet data Center of Korea(NCIA). So, it has need to make an usage-based IT service model that is suitable for public sector. In this paper, we propose the usage-based IT service model that is composed of IT service framework, service pricing model and IT service architecture.

진화하는 모바일 기술은 새로운 스마트폰을 출시하고, 주기적으로 이용자들에게 교체하도록 유도하면서 모바일 기술 속에 이용자들을 가두어놓는 것 같다. 그러나 단순히 기기의 이용이 기술 자체의 속성에 의해 전적으로 결정되는 것이 아닌 바, 이용자들이 '어떻게 수용하고 있으며 인지하고 있는가'에 따라 스마트함에 대한 의미에 차이가 발생할 것으로 보았다. 특히 이 연구에서는 스마트폰의 '스마트함', '스마트하게 이용한다'라는 현상적 개념을 '스마트한 이용'의 개념으로 구체화하였고, 2차 측정모형(second-order measurement model)을 통해 스마트한 이용의 구성개념을 검증하였다. 그 결과 8개로 구성되었던 1차 요인들은 6개로 축소되었는데, 이 과정에서 '사용준비성'과 '미디어 통합성'이 '다기능 사용 준비성'으로 묶였으며, '시간 효율성'과 '관계 연결성'이 '관리 효율성'으로 합쳐졌다. 결과적으로 '스마트한 이용'의 구성개념은 '다기능 사용 준비성', '관리 효율성', '미디어 일체감', '기기연결성', '이용자 중심 최적화', '외부연결성(being connected)'의 6개 요인으로 추출되었다. 이에 스마트한 이용이란, 스마트폰의 기기적 특성을 기반으로 모바일 공간 속에서의 자율적 활용 역량으로 적절히 조율되는 이용행태로 설명될 수 있을 것이다.
