The structure and space construction of local houses and its form of shape were under the influence of the character of locality and times. Each area makes an distinctive culture by spreading the developed culture to an undeveloped area. Frequent interchange were formed between Samcheok and Bonghwa district for a long time ago. But the change of life zone by progressive traffic makes it to a strange area. Accordingly this study clarify the changed shape and form of local houses by selecting and put it on record an scattered along the road of old times.

트리 데이터로부터 유용한 정보들을 추출하는 가장 일반적인 방식은 빈번하게 자주 발생하는 서브트리 패턴들을 얻는 것이다. XML 마이닝, 웹 사용 마이닝, 바이오인포매틱스, 네트워크 멀티캐스트 라우팅 등 빈번 트리 패턴 마이닝은 여러 다양한 영역에서 광범위하게 이용되고 있기 때문에, 해당 패턴들을 추출하기 위한 많은 알고리즘들이 제안되어 왔다. 하지만, 현재까지 제안된 대부분의 트리 마이닝 알고리즘들은 여러 가지 심각한 문제점들을 내포하고 있는데 이는 특히 대량의 트리 데이터 집합을 대상으로 했을 때는 더 심각해진다. 주요하게 발생하는 문제점들로는, (1) 계층적 트리 구조의 데이터 모델링, (2) 후보군 유지를 위한 고비용 계산, (3) 반복적인 입력 데이터 집합 스캔, (4) 높은 메모리 의존성이 대표적이다. 이런 문제점들을 발생하게 하는 주요 원인은, 대부분의 기존 알고리즘들이 apriori 방식에 근거하고 있다는 점과 후보군 생성과 빈발 횟수 집계에 anti-monotone 원리를 적용한다는 점에 기인한다. 언급한 문제들을 해결하기 위해, 본 저자들은 apriori 방식 대신 pattern-growth 방식을 기반으로 하며, 빈번 서브트리 추출 대신 최대 빈번 서브트리 추출을 목적으로 한다. 이를 통해 제안된 방법은, 빈번하지 않은 서브트리들을 제거하는 과정 자체를 배제할 뿐만 아니라, 후보군 트리들을 생성하는 과정 또한 전혀 수행하지 않음으로써 전체 마이닝 과정을 상당히 개선한다.

A simulation of failures on responsible elements is only one form of the extreme structural behavior analysis. By understanding the dynamic behavior in incidental situations, it is possible to make a special structural design from the point of the largest axial force, stress and redundancy. The numerical realization of one such simulation analysis was performed using FEM in this paper. The boundary parameters of transient analysis, such as overall structural damping coefficient, load accelerations, time of load fall and internal forces in the responsible structural elements, were determined on the basis of the dynamic experimental parameters. The structure eigenfrequencies were determined in modal analysis. In the study, the basic incidental models were set. The models were identified by many years of monitoring incidental situations and the most frequent human errors in work with heavy structures. The combined load models of structure are defined in the paper since the incidents simply arise as consequences of cumulative errors and failures. A feature of a combined model is that the single incident causes the next incident (consecutive timing) as well as that other simple dynamic actions are simultaneous. The structure was observed in three typical load positions taken from the crane passport (range-load). The obtained dynamic responses indicate the degree of structural sensitivity depending on the character of incident. The dynamic coefficient KD was adopted as a parameter for the evaluation of structural sensitivity.

This paper investigated the phoneme distribution and phonological processes of orthographic and pronounced phrasal words in light of syllable structure in the Seoul Corpus in order to provide linguists and phoneticians with a clearer understanding of the Korean language system. To achieve the goal, the phrasal words were extracted from the transcribed label scripts of the Seoul Corpus using Praat. Following this, the onsets, peaks, codas and syllable types of the phrasal words were analyzed using an R script. Results revealed that k0 was most frequently used as an onset in both orthographic and pronounced phrasal words. Also, aa was the most favored vowel in the Korean syllable peak with fewer phonological processes in its pronounced form. The total proportion of all diphthongs according to the frequency of the peaks in the orthographic phrasal words was 8.8%, which was almost double those found in the pronounced phrasal words. For the codas, nn accounted for 34.4% of the total pronounced phrasal words and was the varied form. From syllable type classification of the Corpus, CV appeared to be the most frequent type followed by CVC, V, and VC from the orthographic forms. Overall, the onsets were more prevalent in the pronunciation more than the codas. From the results, this paper concluded that an analysis of phoneme distribution and phonological processes in light of syllable structure can contribute greatly to the understanding of the phonology of spoken Korean.

Energy dissipation devices can be considered as an alternative for the seismic performance enhancement of existing structures based on the strengthened seismic design code. In this study, seismic response mitigation effects of friction dampers are investigated through the shaking table test of a full scale 3 story building structure. Frist, the bilinear force-displacement relationship of a structure-brace-friction damper system and the effect of brace-friction damper on the increase of frequency and damping ratio are identified. Second, frequency, displacement, and torque dependent characteristics of the friction damper are investigated by using harmonic load excitation tests. Finally, the shaking table tests are performed for a full scale 3 story steel frame. System identification results using random signal excitation indicated that brace-friction damper increased structural damping ratio and frequency, and El Centro earthquake test showed that brace-friction damper reduced the peak displacement and acceleration significantly. In particular, it was observed that the damping effect due to friction damper becomed obvious when the structure was excited by more intensive load causing frequent slippage of the friction dampers.

The Heian Period(794-1192) was the period when luxury and elegance flourished. Gorgeous colors were adopted for the costumes and an el-egant assortment of colors prevailed. Representatiove of such costumes is kasane-no-irome. The world Kasane-no-irome originally came from two colors on both sides of one of the japanese kimonos called Uchiki. In later times it turned to indicate the combination ef-fect of colors of several Uchiki's worn in layers one over the other. This paper describes in de-tail the kasane-no-irome in both meanings. In so doing I distinguish two different kinds of kasane-no-irome using a Chinese character for the formed and for the latter though both are pronounced Kasane in the Japanese language. Part one of this paper which concerns the color combinations of presents typical 148 samples through reproduced dyeing clothes by Matumoto. Part two describes the color com-bination of which was so called Junihitoe. It presents typical 41 samples from reproduced dyeing clothes by Matumoto. The purpose of this study was to investigate the characteristics of color distribution and the structure of color combination in Kasane-no-irome. Therefore we obtained the following results in Kasane-no-irome. 1. The color combination of Kasane-no-irome came from the natural color harmony there-fore the names of kasane-no-irome which adopt the names of flowers and leaves of the foure seasons. Accordingly the seasons for wearing them are fixed. 2. In the hue the most frequent appearance was green. And in the tone the most frequent apperance was moderate. 3. In the color combination the most fre-quent type were monochromatic combination and contrast combination.
