민성길,김동기,박진균,전세일 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3

연구목적 : 건간한 의대상 312명과 신경증적 장애를 가진 환자 288명을 대상으로 하였다. 사상체질의 구별은 노정우 및 김달래 두 전문가에 의한 판정, 그리고 경희의대 사상체질 설문지(QSCC Ⅱ)에 의한 판정 등 3가지 방법에 의하였다. 연구 대상에게 정신과적 증상척도(SCL-90), 체질특성척도 및 성격척도를 사용하여 자가 평가하게 하였다. 각종 척도들의 타당도와 신뢰도는 입증되었다. 이 척도들을 통계적으로 분석하고 고전적 설명과 어느 정도 일치하는 지를 검토하였다. 연구결과 : 1) 3가지 분류방법간에 차이가 컸었다. 그 중 전문가의 직접적 면담에 의한 감별보다 QSCCⅡ 설문지형이 비교적 감별력이 컸다. 3) QSCCⅡ가 감별력이 비교적 크다고 하더라도 그 결과가 소음군의 대인공포-강박증, 불면-식용상실, 무력-예민-소화기-한기-피부증후군 그리고 정력부족등 신경증적 증상과 소극-비사교적, 내향형 성격 및 이성적 성격특징 등 몇가지 특징을 감별하는 데에만 비교적 유의하였고, 태음군의 특정인 독특한 신념, 온기, 활달-사교적 성격에 대해서는 부분적으로 그 특징을 감별하였다. 또한 소양군의 활달-사교형 성격과 감정형 성격의 특징 등은 극히 부분적으로 감별하였다. 결 론 : 이러한 결과는 현존하는 사상체질 구분방법에 일치점이 결여되어 있다는 것, 각종척도를 사용한 결과는 사상체질에 관한 고전적 설명을 부분적으로만 입증하고 있다는 것, 따라서 사상체질구분에 대한 향후보다 객관적인 연구가 필요하다는 것을 시사한다. Object : This study is to examine the validity of constitutional classification of Sa-sang medical theory. This theory classifies the human constitution to 4 types according to classical oriental philosophy on yin and yang. Subjects and Method : Subjects were 312 medical students and 288 neurotic patients with diagnosis of neurotic, stress related and somatoform disorders and minor depressive episodes according to ICD-10. Medical students were classified to 4 Sa-sang Constitution Classification(QSCCⅡ). For assessmnent of symptoms and signs, Korean version of SCL-90, a constitution scale and personality scale which were designed for this study were used. These instruments were found to be reliable and valid through statistical analysis. Subjects were asked to rate these scales. The data were analysed with factor analysis and factor scores were compared among 4 Sa-sang constitutions by ANOVA and t-test. The data from patient group were analysed with factor analysis and the results were compared with the Sa-sang medical theory. Results : Results of classification by 3 ways were inconsistent showing a significant difference among them. Among them, QSCCⅡ was most reliable. In QSCC Ⅱ, only the factor scores of factors of homophobia-obsession, weakness-sensitiveness-indigestion-chillness-skin syndrome, sexual weakness, passive-unsociable personality, introverted personality and rational, personality, were significantly high in So-um (small yin) group of medical students. A factor of warmnes and active-sociable personality were significantly high in Tae-um(big yin)group. Also active-sociable and effective pesonality was partly related with So-yang(small yang)group. Conclusion : These results suggest that those present classification methods inconsistent, that these methods are proving only parts of Sa-sang medical theory, and that objective and scientific studies are needed for reliability and validity of Sa-sang medical theory.

배민규(Min-Gyu Bae),윤천성(Chun-Sung Youn) 한국뷰티산업학회 2023 뷰티산업연구 Vol.16 No.2

본 연구는 ‘내향성 발톱 교정에 관한 사례 고찰 연구’로서 보다 효과적인 내향성 발톱 교정 방안을 제안하고자 함에 있다. 고찰하여 분석한 결과 배민규, 윤천성(2022)은 내향성 발톱 예방 및 개선⋅교정을 목적으로 활용한 레진 젤(크랄레젤)을 활용한 내향성 발톱 교정 방법이 제품 활용 편리성, 문제점 등에서 다른 연구자들의 연구방법에 따른 문제점 등과 비교했을 때 활용 가치가 있을 것으로 판단했다. 다만 기존 다른 연구자들의 아크릴 스캅춰, Brace System, 실크, 와이어 등 제품들에 비해 교정 효과가 비교적 낮아 김경환(2022) 연구자가 내향성 발톱 교정 효과성 검증을 위해 활용했던 견인기를 함께 활용하기를 제안한다. 내향성 발톱 예방 및 재발 방지를 목적으로 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버 1회 적용을 제안하고, 내향성 발톱 개선 및 교정을 목적으로 김경환(2022) 연구자가 활용한 견인기를 활용하여 발톱을 펴준 후, 배민규, 윤천성(2022) 연구자가 제안한 크랄레젤 리커버를 목적에 맞게 2~5회 적용하여 활용하기를 제안한다. 본 연구 자료가 내향성 발톱 질환으로부터 건강한 삶을 영위하기 위한 자료로 활용될 수 있기를 기대해 본다. As “a case study on the correction of ingrowing nail”, this study aims to suggest more effective measures for the correction of ingrowing nail. In the results of considering and analyzing it, the correction of ingrowing nail using the Resin Gel(Kralle Gel) which was used by researchers Min-Gyu Bae & Chun-Sung Youn(2022) for the purpose of preventing, improving, and correcting the ingrowing nail, seemed to be more useful than other methods used by other researchers in the aspect of convenience of product use and problem. However, compared to the products like Acrylic Sculpture, Brace System, Silk, and Wire used by other researchers, the effect on correction was relatively lower, so it is proposed to be used together with the Retractor that was used by Kyeong-Hwan Kim(2022) for verifying the effectiveness on the correction of ingrowing nail. This study suggests applying Kralle Gel Recover one time suggested by Min-Gyu Bae & Chun-Sung Youn(2002) for the purpose of prevention & recurrence prevention of ingrowing nail, unbending the nail by using the Retractor used by a researcher Kyeong-Hwan Kim(2022) for the purpose of improving/correcting the ingrowing nail, and then applying Kralle Gel Recover 2-5 times suitable for the purpose, suggested by researchers Min-Gyu Bae & Chun-Sung Youn(2022). The results of this study are expected to be utilized as the data for enjoying a healthy life from ingrowing nail disease.

ATM망에서 ABR서비스를 위한 효율적인 전송률 할당 알고리즘에 관한 연구

천재호,윤상호,김명균,허정석 울산대학교 1999 공학연구논문집 Vol.30 No.2

ATM망에서 ABR 서비스는 CBR, VBR에 할당된 대역폭을 제외한 나머지를 이용해서 데이터를 전송한다. 오디오 또는 비디오 데이터와 같이 실시간 전송이 필요한 서비스들을 전송지연이 제한되는 CBR이나 VBR 트래픽을 이용하여 제공할 수 있지만, 이런 경우에는 전송 대역폭을 효율적으로 사용하지 못하는 단점이 있다. 본 논문에서는 실시간 데이터를 ABR 서비스를 이용하여 효율적으로 전송하기 위한 ABR 대역폭 할당 알고리즘을 제안한다. 제안된 알고리즘은 MCR을 보장하며, MCR에 비례해 전송률을 할당한다. 그리고 접속의 상태를 만족(satisfied)상태와 불만족(bottlenecked)상태로 구분하고, 만족 상태인 접속이 사용하지 않는 대역폭을 불만족 상태인 접속이 사용할 수 있도록 하여 대역폭 활용도를 높인다. 또한 제안된 알고리즘은 큐 제어 함수를 사용해서 큐 길이를 일정한 범위로 유지함으로써 셀의 전송지연을 일정하게 한다. 본 논문에서는 시뮬레이션을 통해 제안된 알고리즘의 성능을 분석하고, 기존에 제안된 ATM 포럼[1]및 Kalampoukas 알고리즘[2]과 비교를 하였다. On ATM networks, ABR services are provided using the remained bandwidth after allocating CBR and VBR traffic. Realtime services such as transmitting audio or video data may be provided using CBR and VBR which have a constrained transmission delay, but in those cases, the communications bandwidth may be wasted. This paper proposes an efficient ABR rate allocation algorithm to transfer real-time data using ABR service. The proposing algorithm guarantees MCR and allocates bandwidth to each connection proportional to its MCR. The proposing algorithm divides the connections in two groups, a satisfied state group and a bottlenecked state group, and enhances bandwidth utilization by allowing the remained bandwidth after allocating to the connections in the satisfied state to the connections in the bottlenecked state. The proposing algorithm uses the queue control function to keep the queue length within some boundary, which makes the transmission delay constant. We simulate and compare the performance of the proposing algorithm with that of the algorithms proposed by ATM Forum[1] and Kalampoukas[2].

전치부 개방교합을 지닌 상악골 및 하악골 전돌증의 치료 : 증례 보고 A Case Report

천상득,진병로 영남대학교 의과대학 2004 Yeungnam University Journal of Medicine Vol.21 No.2

In general, the skeletal class Ⅲ has the characteristics of mandibular overgrowth with a normal maxillary growth or maxillary undergrowth with a normal mandibular growth And clinical and radiographic evaluations of the patient are needed. However, the treatment plan is not dependent on these evaluations alone, because patient's general condition and hope for aesthetics varies. The aim of this report is to consider the treatment of a medically compromised patient with an anterior open bite and skeletal class Ⅲ, which showed a severe mandibular overgrowth. In 2003, a 17-year-old boy with epilepsy, mental retardation presented at our clinic complaining of concave profile. A clinical examination showed severe mandibular prognathism with an anterior open bite. The radiographic examination revealed a short cranial base, a moderate maxillary overgrowth, severe mandibular overgrowth and skeletal open bite tendency. In 2004, he was verified to have no potential of growth by hand-and-wrist radiographs and an endocrine examination. He completed the preoperative orthodontic treatment and orthognathic surgery (sagittal split ramus osteotomy, genioplasty). He was evaluated on the first visit, the preoperative period and the postoperative period with a clinical and radiographic examination. At the first visit, the patient showed moderate overgrowth of the maxilla, severe overgrowth of the mandible, and a subsequential skeletal open bite. After the preoperative orthodontic treatment (preoperative period), the patient showed the same skeletal problem as before and a decompensated dentition for orthognathic surgery. After orthognathic surgery, his profile had improved, but he had still a skeletal open bite tendency because the maxillary orthognathic surgery was not performed. Severe mandibular prognathism with a maxillary overgrowth and anterior open bite should be treated by bimaxizlary orthognathic surgery. However, one-jaw orthognathic surgery on the remaining the skeletal open bite tendency was performed for his medical problem and facial esthetics. This subsequential open bite should be resolved with a postoperative orthodontic treatment.

개별공시지가 검증제도에 대한 실증적 분석

성춘자,송은지 남서울대학교 2005 남서울대학교 논문집 Vol.11 No.2

An analysis of objection request of individual public land price in the Choongju-city indicates that the ratio of objection request is higher than that of an average of the whole country. More than 70% requests out of the total objection request fields requests downward adjustment. Especially, it has been requested downward adjustment centering around a farm and forest land which are located on the town and township for the purpose of tax reduction. However, an objection request of individual public land price is not based on the absolute land value but based on personal interests. Thus, the downward or upward request without a fundamental rule tends to wastes the time and budget. As an alternative, there is need to introduce the scientific system, ALPA, which both selects a comparative standard land and applies land value ratification automatically. With the ALPA, it will increase the confidence of individual public land price. Furthermore, there will be only one time verification procedure before the determination·public announcement of individual public land price.
