This is the case report of huge complex odontoma treated with sagittal splitting of buccal bone plate and iliac bone graft in left mandible angle. The 22 years old patient was admitted to the department of Oral and Maxillofacial Surgery of Kyungpook National University Hospital with the chief complaint of swelling on the left mandible angle area. We used extra oral Risdon incision and splitted the buccal cortical bone after making the horizontal bone cut buccally. The tumor mass was removed with cutting into the pieces with surgical bur to prevent mandibular fracture. The dead space was grafted with autogenous iliac bone graft and the splitted buccal cortical bone was fixed with two L-type miniplate. After 12months follow up check, we noticed good process of bone healing and satisfactory aesthetic result. In this case, my operative approach provided the excellent surgical access to the hard tissue mass and minimized post operative complication comparing with the conventional surgical approaches.

Objectives The purpose of this study was to examine the effects of positive and negative emotion on the quality of life(QoL) in each Sasang contitution, using Positive Affect and Negative Affect Schedule(PANAS) and Short Form-12 Health Survey Questionnaire(SF-12) questionnaire. Methods A total of 1,123 participants completed the Korean version of the PANAS and SF-12 questionnaire. The participants were classified into one Sasang constitution by QSCC II. The effects of emotion on the QoL were compared between the each Sasang contitution using analysis of variance(ANOVA). Results We found significant differences between constitutions in Positive Affect(PA), PA-Joy, PA-Interest and PA-Activation of PANAS. And we found significant differences between constitutions in Mental Component Summary(MCS) of SF-12. Negative correlation of less -0.4 was shown in Negative Affect(NA), NA-Afraid, NA-Upset of PANAS and MCS of SF-12. Conclusions The Soyangin has significantly higher score than Soeumin in PA, PA-Joy, PA-Interest and PA-Activation of PANAS as previous studies. This study also shows the correlation between negative emotion and decline in the quality of mental status.

Objectives The body shape was a key information for diagnosing the Sasang constitution (SC) in Sasang constitutional medicine. The aim of this study was to compare the body shapes and mainly focusing on the Korean and Chinese-KoreanMethods We calculated the propensity score for each SC type in males and females separately, and compared body shape including 8 circumference and 5 width between Korean and Chinese-Korean according to the sex and SC.Results Koreans have larger trunk and hip area compared to Chinese-Koreans, while Chinese-Koreans have larger abdomen compared with Koreans. Most variables were significantly different among SC types, for both Korean and Chinese-Korean. Especially, the Taeumin (TE) type has the largest body shape compared with the other SC types, it was similar between Korean and Chinese-Korean.Conclusions This study showed that the TE type has the largest body shape, followed by Soyangin (SY) and Soeumin (SE) in order, for both Korean and Chinese-Korean respectively. These results suggests that the body shape of Chinese-Korean is similar with Korean based on SC type.

An Enhanced Density and Grid based Spatial Clustering Algorithm for Large Spatial Database

김호석,김경배,배해영,Gao, Song,Kim, Ho-Seok,Xia, Ying,Kim, Gyoung-Bae,Bae, Hae-Young 한국정보처리학회 2006 정보처리학회논문지D Vol.13 No.5

Spatial clustering, which groups similar objects based on their distance, connectivity, or their relative density in space, is an important component of spatial data mining. Density-based and grid-based clustering are two main clustering approaches. The former is famous for its capability of discovering clusters of various shapes and eliminating noises, while the latter is well known for its high speed. Clustering large data sets has always been a serious challenge for clustering algorithms, because huge data set would make the clustering process extremely costly. In this paper, we propose an enhanced Density-Grid based Clustering algorithm for Large spatial database by setting a default number of intervals and removing the outliers effectively with the help of a proper measurement to identify areas of high density in the input data space. We use a density threshold DT to recognize dense cells before neighbor dense cells are combined to form clusters. When proposed algorithm is performed on large dataset, a proper granularity of each dimension in data space and a density threshold for recognizing dense areas can improve the performance of this algorithm. We combine grid-based and density-based methods together to not only increase the efficiency but also find clusters with arbitrary shape. Synthetic datasets are used for experimental evaluation which shows that proposed method has high performance and accuracy in the experiments. 공간 데이터마이닝 분야에서 객체간의 거리, 연결성, 상대적인 밀도를 기반으로 비슷한 객체들을 하나의 그룹으로 묶는 공간 클러스터링은 중요한 컴포넌트이다. 공간 클러스터링 알고리즘은 밀도 기반 클러스터링과 격자 기반 클러스터링 알고리즘 등으로 나눌 수 있다. 밀도 기반 클러스터링 알고리즘은 다양한 모양과 크기의 클러스터를 구분할 수 있으며, 잡음을 제거할 수 있는 장점을 가지고 있는 반면에, 격자 기반 클러스터링 처리속도가 빠르다는 장점을 가지고 있다. 하지만, 대량의 공간 데이터 집합을 클러스터링 하는 것은 데이터 처리 비용이 급격하게 증가하기 때문에 클러스터링 처리 결과에 큰 영향을 준다. 본 논문은 대용량의 공간 데이터베이스에서 공간 객체간의 고밀도 영역을 식별하여 잡음을 제거하기 위한 수치데이터 값과 기본 격자간격 개수를 정의하는 확장된 밀도-격자 기반 클러스터링 알고리즘을 제안한다. 제안 알고리즘은 고밀도 영역 식별을 위하여 threashold(DT)를 정의하였으며, 격자 및 밀도 기반 기법의 장점을 이용하여 임의의 객체 클러스터링을 식별할 수 있는 성능을 향상시켰다. 성능평가에서 기존의 클러스터링 알고리즘과의 다양한 비교 평가 실험을 통하여, 제안 알고리즘이 빠르고 정확한 데이터 클러스터링 결과를 나타냄을 보인다.

Recently, Electric Power Steering(EPS) system has become widely equipped in the vehicles. EPS system, which generates the assist torque by an electric motor, has many advantage in comparison with the conventional hydraulic power steering system. But EPS system may have drivers feel the displeasure because the lack of steering return-ability results from the mechanical friction loss. To improve the steering return-ability for EPS system, this paper develops a new EPS strategy which modulates the signal of torque sensor by estimating the alignment torque.

황해도 탈춤음악의 전승과 선율구조

김호석 ( Ho Seok Kim ) 한국음악사학회 2009 한국음악사학보 Vol.43 No.-

한국의 탈춤은 춤·대사·음악의 3요소로 구성되는데, 그중에서도 음악은 춤의 반주로 사용되는 반주음악과 대사 중에 나오는 노래로 구분할 수 있다. 탈춤의 춤과 대사는 일찍이 관심있는 학자들의 연구와 채록활동을 통해 그동안 많은 연구논문과 저서들이 발표되었지만, 음악에 관하여는 최근에 임혜정과 이진원이 발표한 논문 외에 필자가 출간한 『탈춤음악본총서 1·2·3』권이 고작이다. 따라서 본고는 탈춤음악 중 필자가 직접 전승 및 연주활동에 참여하고 있는 황해도탈춤을 중심으로 반주음악의 전승실태와 선율구조의 특징 및 연주기법에 대하여 알아보고, 대사 중에 연희자들이 부르는 노래의 선율구조에 대하여 살펴보고자 한다. 먼저 반주음악의 전승실태에 관해서는, 6.25전쟁 후 월남한 예술인을 통해 명맥을 이어온 황해도피리가락이 오선보를 활용한 그룹지도를 통해 현재 봉산탈춤·강령탈춤·은율탈춤 등 황해도탈춤의 반주음악악사들에게 전승되어 연주되고 있을 뿐만 아니라, 2000년부터는 한국예술종합학교 전통예술원을 비롯한 서울지역 주요대학 국악과의 피리전공자들을 대상으로 열린 하계강습을 통해 서도풍류라는 연주곡목으로 전승되어 연주회장에서 수회 발표되기도 하였다. 이러한 황해도탈춤의 반주음악은 피리2·대금1·해금1·장고1·북1·징1 등 모두 6명으로 구성된 삼현육각편성으로 연주되고 있지만, 편의상 쌍피리와 타악기의 편성으로 연주하기도 하며, 놀이의 흥을 돋우기 위해 길놀이 및 몇몇 과장에서는 태평소와 타악기만으로 연주하기도 한다. 현재 연주되고 있는 황해도탈춤의 반주음악에는 해주가락·재령가락·은율가락 등이 있는데, 해주가락과 재령가락은 봉산탈춤과 강령탈춤의 전 과장에서 반주음악으로 연주되고 있으며, 특히 해주가락 중 타령은 은율탈춤공연에서도 연주되고 있다. 반면 은율가락인 긴염불은 은율탈춤공연에서만 제한적으로 연주되고 있는 실정이다. 또한 연주기법에 있어서 해주가락의 경우 서도소리의 창법이 묻어있지만, 재령가락과 은율가락의 경우에는 연주기법은 해주가락의 특징을 적용하되 선율구조는 「솔-라-도-레-미」로 되어있다. 다음으로 황해도탈춤에서 연희자들이 부르는 노래의 선율구조를 살펴보면, 강령탈춤에 나오는 물레타령이 유일하게 수심가토리이고 경토리가 가장 많으며, 육자백이토리와 메나리토리의 곡이 골고루 분포되어 있다. 또한 경토리로 되어있는 곡의 일부는 창법에 있어서 서도소리의 창법을 적용하기도 한다. Hwanghaedo Mask Dance Music could be preserved till today because of devotional endeavors of Pak Tong-sin, Kim Yong-t`aek, and Yang So-un. Hwanghaedo mask dance music is divided into the instrumental accompaniment music and songs that are sung by performers. The accompaniment music is divided into Pak Tong-sin`s Hwanghaedo p`iri Tunes that are performed in Pongsan t`alch`um, Kangryong t`alch`um, and Unyul t`alch`um, and Kim Yong-t`aek`s Unyul Tunes and t`aep`yongso Tunes that are played in Unyul t`alch`um. Songs were transmitted from Yang So-un to all of three organizations preserving Hwanghaedo mask dance and 68 songs survive. Hwanghaedo p`iri Tunes consists of Haeju tunes - yombul, t`aryong, and kukkori - that were transmitted to from Chong Mok-tong and Yi Ho-yun and Chaeryong tune - t`aryon sinawi - that Pak adopted from Chaeryong p`iri players. These pieces are played throughout the entire acts in Pongsan t`alch`um and Kangryong t`alch`um and t`aryong is played in Unyul t`alch`um. Among Kim Yong-t`aek`s Unyul Tunes and t`aep`yongso Tunes, kin yombul, chajin tomburi, tol changdan, and unyul kut changdan are played as accompaniment music of Unyul t`alch`um. Hwanghaedo p`iri Tunes, that were transmitted to the writer from Pak Tong-sin, are still in the process of transmission to the next generation throughout courses in the Korean National University of Arts and special summer courses in every other year. Besides, it became an independent instrumental genre to be performed on the stage being recognized as sodo p`ungnyu. The accompaniment music of Hwanghaedo mask dance are divided into three categories according to it musical frames. The first is Haeju karak that consist of sol-(la)-re -mi; yombul, t`aryong, and kukkori are haeju karak. Second, the scale is formed with sol-la-do-re-mi including t`aryong karak, t`aryong sinawi, unyul karak, kin yombul, and t`aep`yongso karak, chajin tomburi, tol changdan, and unyul kut changdan. Third, the scale is formed with la-do-re-mi-sol. The instrumentation of the accompaniment music of Hwanghaedo mask dance should be samhyon yukkak; however, only Pongsan t`alch`um is accompanied with Samhyon yukkak; Kangroong t`alch`um only with two piri and one taegum; Unyul t`alch`um with two p`iri and one t`aepyongso. Performing techniques of p`iri, witch is the main instrument of the accompaniment music, can be discussed with the three main techniques. The first technique is the throat technique which is expressing a little lower tone than re as a staccato on the first hole. The second technique is expressing re by holding the reed deeply vibrating the pitch deeply on the second hole. The third technique is expressing the pitch of the back hole with the long sustentation and vibration at the end. These techniques not only appear in Hwanghae-do piri Tunes but also Unyul Tunes. Songs that are sung in Hwanghaedo mask dances are divided according to dances and categorized according to their tori, regional styles. If the scale of a song is the same as sol-la-do-re-mi or la-do-re-mi-sol, it is kyong t`ori. If the scale of a song is the same as mi-la-ti-do-re with the characteristic ti, it is yukchabaegi t`ori. Mi-sol-la-do-re is known as menari t`ori, and re-la-do or la-mi-sol, which is perfect fifth above re-la-do, is susimga t`ori. Some of non-harmonic tones - for example, passing tones, neighboring tones, and escape tones - may appear. Among sixty-eight pieces that are sung in Hwanghaedo mask dance, thirty-five pieces are kyong t`ori. which is more than a half, twenty one pieces are yukchabaegi t`ori, which is 1/3 of the entire, ten pieces are in menari t`ori, one is susimga t`ori, and one is p`yong sijo. As utilizing the staff notation instead of the oral transmission, the system of transmission became more efficient and it made the group lecture possible; and thus, Hwanghaedo p`iri Tunes, which were in danger to be lost, have been popularized in the traditional music society. In addition, it became rigid not only as the accompaniment music of Hwanghaedo mask dance but also as an instrumental genre known as sodo p`ungnyu.
