  • Purpose: We performed this study to examine the correlationship between EEG complexity and impedance cardiography data using correlation analysis. Method: This study performed on 30 healthy subjects(16 males, 14 females). Before and after natural respiration, ICG data were recorded, and EEG raw data were measured by moving windows during 15 minutes. The correlation dimension(D2) was calculated from 15 minutes data. 8 channels EEG data were analysed with 9 index of ICG data by correlation analysis. Result: 1. ACI of impedance cardiography had significant correlationship with ch.4 of EEG complexity(p=0.03). 2. VI of impedance cardiography had significant correlationship with ch.3 of EEG complexity(p=0.034) and ch.4 of EEG complexity(p=0.017). 3. HR, TFC, PEP, LVET, STR of impedance cardiography had no significant correlationship with all of 8 channel EEG complexity. Conclusions: These results suggest that nonlinear analysis of EEG and impedance cardiography have some significant correlationship. And it can make out relationship between brain system and cardiovascular system. In the future, therefore, more study of these fields are necessary.

  • 지역별 적정 주택량을 공급하기 위해 수요예측 모형을 구축한다 예측모형은 자료유형에 따라 다소 차이가 있으나 시계열자료(Time Series Data) 분석기법에 의한 모형 구축 시 추정대상 지역특성을 민감히 반영할 수 있는 영향인자가 필요하다. 도시지역을 인구규모로 분류하여 영향인자를 분석할 경우, 대도시와는 달리 중 $\cdot$ 소도시는 주택량과 상수도보급률의 변화가 일정기간 민감한 상관관계가 존재하는 것으로 조사되고 있다. 이에 따라 중 $\cdot$ 소도시 주택수요 예측을 위해 상수도보급률을 유용하게 적용할 수 있는 구간, 즉 예측모형 구축이 가능한 시점까지의 도시 주택량과 인구수 규모를 찾아낼 필요가 있다. 따라서, 전국 중 $\cdot$ 소도시를 대상으로 주택량과 상수도 보급률의 상관관계가 중 소도시 지역에서만 있는 것으로 조사된 기존 연구 결과를 재 입증하고, 지역별 상관관계가 완화되는 시점의 시기, 상수도보급률, 주택량, 인구수 규모를 발견하는 것을 본 연구의 목적으로 한다.

  • The osteoporosis is a disease that represents a reduction in the volume of bony tissue relative to whole bone volume. And mandible also may be affected. Such porotic mandible may influence the result of the surgery like dental implant surgery relating mandible. So, the author examed the panoramic view of 89 persons for finding the possibility of useful diagnostic parameters of osteoporosis. To know the correlationship between the condition of vertebra and mandible, bone marrow density of lumbar spine from 2nd to 4th, and the number of residual tooth, panoramic mandibular index (PMI), angular cortical bone thickness (ACT) and ramus cortical bone thickness (RCT) were compared. The result is that PMI and ACT have similar relative weak linear correlationship, RCT have very weak linear correlationship, the number of residual tooth have not linear correlationship.

  • 공정능력을 측정하고 분석하기 위하여 공정능력지수가 매우 중요한 역할을 한다. 흔히 품질수준은 공정능력지수들에 의해 측정된다. 세 가지 공정능력지수 $C_p$, $C_{pk}$, $C_{pm}$들은 품질 현장에서 프로세스 성과를 평가하는 데 널리 유용하게 사용되는 바, 이들 추정량들의 상관관계를 보다 명확하게 규명, 연구하여 적절히 활용할 필요가 있다. 본 논문에서는 공정표본이 정규분포에 따를 때 이러한 지수들의 추정량들에 대한 점근적 상관성을 연구하였다. 제2절에서는 공정능력지수 $C_p$, $C_{pk}$, $C_{pm}$들을 정의하여 기본적인 관계를 설명하였고, 제3절에서는 단일변량 정규공정하에서의 점근적인 상관계수를 구체적으로 계산, 규명하였다. 이러한 연구결과를 이용하여 보다 정확한 공정능력지수들의 상관관계를 통해 필요한 분석을 수행하는 것이 바람직할 것이다.

  • Objectives: The purpose of this research is to investigate correlationship between Hwa-Byung and various factors, including Sasang Constitution. Methods: The research about Hwa-Byung, various factors and Sasang Constitution were carried out for 649 Participants, male was 272 and female was 377. Hwa-Byung diagnosed by Hwa-Byung Diagnostic Interview Schedule(HBDIS). Sasang Constitution was diagnosed by a Sasang Constitutional specialist with recorded voices, face pictures, tongue pictures and researched data about Sasang Constitution. Collected data were analyzed by the qui-square test and t-test. Results: 1. The prevalence of Hwa-Byung in Taeeumin and Soeumin were higher than that of Soyangin but it was not significant. 2. In the case of meeting frequency of friends, Hwa-Byung group was higher than none Hwa-Byung group and it was significant. 3. In the case of existence of negative influencing people, the rate of Hwa-Byung group was higher than that of none Hwa-Byung group. Among them, Interfere, Blame, Discomfort and Indifferent were significant. Conclusions: Hwa-Byung may have correlationship with Sasang Constitution, meeting frequency of friends and existence of negative influencing people.

  • Objectives : The purpose of this study was to investigate the relationship between pain and psychological state in female office workers with neck pain. Methods : Experimental group of 31 healthy subjects complained of neck and arm discomfort related to computer use which lasted more than 3 months in the past year and was present in the past 7 days as well as on the day of test. Outcomes were assessed by meridian-electromyography(MEMG), Neck Disability Index(NDI), Visual Analog Scale(VAS), Beck Depression Inventory(BDI), Stress Reaction Inventory(SRI), Holmes & Rahe Social Readjustment Rating Scale(SRRS). Results : The NDI score and BDI score had a correlationship(r=0.48), and the NDI score and SRI score also had a correlationship(r=0.48), significantly. The NDI score and contraction power of upper trapezius by MEMG had a correlationship significantly, but with the other muscles the NDI score didn't have correlationships. The NDI score and the SRI score were significantly higher in depression group(BDI score ${\circ}{\surd}$14). The contraction power of trapezius by MEMG was significantly lower in depression group. Conclusions : The results suggest that mental stress can be a major risk factor of neck pain in female office workers.

  • The purpose of this study is to investigate the correlationship between Pantographic Reproducibility Index(PRI) scores and patterns of mandibular movements by mandibular kinesiograph(MKG) that has been used to diagnose temporomandibular disorders. PRI scores have been measured in normal and symptom groups by tracing Denar mechanical pantograph. Maximum lateral deviation, opening & closing velocity, and clinical rest position of mandibular movements have been analyzed in the same group when the mandible is opened and closed. According to to Helkimo's Dysfunction Index, the students and graduates of College of Dentistry are classified as 6 normal groups and 42 symptom groups. The obtained reslts are as follows : 1. The mean of PRI scores was larger in symptom groups than in normal groups. 2. The mean of maximal laterotrusion in frontal trajectory was larger in symptom groups than in normal groups. 3. There was little significant correlationship observed between PRI scores and patterns of mandibular movements by MKG.
