Background: Pattern identification is a unique diagnostic method of traditional Oriental medicine that has recently been the target of questionnaire-based research. Sasang (four-types) constitutional medicine (SCM) is a practice in traditional Korean medicine that seeks to promote objectivity in diagnostics. This paper attempts to illuminate the relationship between constitutions and the pathogenic factors of pattern identification through questionnaires completed by menopausal women about their symptoms. Methods: From March to October 2012, we examined 291 women from the general population, with ages ranging from 40 to 60 years, applying the Kupperman index, the Menopause-Specific Quality of Life Questionnaire (MENQOL), pattern identification based on the Diagnosis System of Oriental Medicine (DSOM), and SCM. We then analyzed the relationship between constitutional type and pathogenic factors. Results: No significant differences were found in the scores of either the Kupperman index or MENQOL questionnaire in relation to constitutional type. However, in a statistical analysis correlating the DSOM pathogenic factor scores (PFS) with the scores of the Kupperman index and MENQOL vasomotor subscale, heat showed a significant positive correlation with SoYang type (SY) and TaeEum type (TE), but not SoEum type (SE), while insufficiency of yin and insufficiency of yang, as well as blood deficiency, showed a significant positive correlation with the TE and SE types. Conclusion: The pathogenic factors in the menopausal symptoms of middle-aged women, specifically the prominent menopausal symptom of facial flushing, differed significantly according to constitutional type.

This study was performed to evaluate the relation between the interval of supportive periodontal therapy and the prevalence of the subgingival microflora. The subgingival plaques from 108 patients were used in the study. Control group were the patients with no periodontal treatment and test groups were assigned into 3 groups according to the period of recall check: group 1; 1-2 months, group 2; 3-4 months, group 3; 6months or more. The polymerase chain reaction (PCR) used for direct identification of periodontal pathogens (P. gingivalis, T. forsythensis, T. denticola) in subgingival plaque. The results of this study were as follows. 1. The prevalence of P. gingivalis, T. forsythensis, T. denticola in control group were 100%, 87%, 90%. 2. In clinical parameters such as plaque index, gingival index, bleeding on probing, control group was not significant different with group 1 but Significant different with group 2, group 3. 3. In group 1, the majority of P. gingivalis had type II fimA. 4. When group 3 were compared with group 1, the prevalence of P. gingivalis increased. But the prevalence of P. gingivalis with type II fimA, which have the virulence factor, decreased. 5. We were unable to find the correlation between P. gingivalis with type IV fimA and periodontal disease. 6. The prevalence of T. forsythensis, T. denticola in test group were 85%, 93% or more. From the above results, we were able to find the relation between the interval of supportive periodontal therapy and the prevalence of the subgingival microflora and the need of the strict supportive periodontal therapy to prevent recurrence of periodontal disease, because there were high prevalence of periodontal pathogens.

This paper is concerned with a computational method for recovering a crack shape of steam generator tubes of nuclear plants. Problems on the shape identification are discussed arising in the characterization of a structural defect in a conductor using data of eddy current inspection. A surface defect on the generator tube ran be detected as a probe impedance trajectory by scanning a pancake type coil. First, a mathematical model of the inspection process is derived from the Maxwell's equation. Second, the input and output relation is given by the approximate model by virtue of the hybrid use of the finite element and boundary element method. In that model, the crack shape is characterized by the unknown coefficients of the B-spline function which approximates the crack shape geometry. Finally, a parameter estimation technique is proposed for recovering the crack shape using data from the probe coil. The computational experiments were successfully tested with the laboratory data.

This study looks over the relation between propeller and noise in ship stern structure. Near field noise and vibration measurements are compared with the analytical results using wave number method. To avoid singularity in wave number integration method, fast field method is introduced. Analytical results show that main transmission mechanism of high frequency noise is structure-borne type and that of low frequency noise is a air-borne type.

본 연구는 정보 검색(Information Retrieval)과정에 있어 검색 기술의 적합성을 향상하기 위하여, 질의어 사이의 유용한 관계를 드러내도록 사례를 분석하고, 질의자의 의도를 파악할 수 있게끔 구체화하도록 연구한 것이다. 이를 위하여 먼저, 질의어가 가지는 어휘 의미적 연구 분야와 존재론적 연구 분야의 관련 연구들을 분석하였으며, 국내.외의 어휘 의미론적 네트워크 사례와 정보 검색 기술이 적용된 사이트의 실제 데이터를 분석하여 관계 유형을 추출하고 분석하였다. 다음으로는 일반적으로 검색자가 직면하는 검색 상황에서 자주 발생하는 문제를 중심으로 문제점을 정의하여 해결 방안을 모색하였다. 현행 검색 기술에서 색인어와 질의어를 단순 비교하여 결과를 쏟아주는 검색은 사용자를 혼란하게 하기 때문에 개선이 필요하고, 질의자의 의도에 맞는 질의 결과를 줄 수 있도록 지능적 검색으로 개선할 필요가 있다. 문제점 해결 방안에 있어서는, 두 질의어 사이의 관계를 드러냄으로써, 검색자의 의도를 인식하고 식별 및 처리할 수 있는 방안이 필요하였다. 질의어들에 관한 실제 사례를 분석하고 관계 유형을 9가지로 분류함으로써, 관계 유형을 디자인하는 방법을 적시하였으며, 관계 유형의 명칭 부여와 관계 역할의 명칭을 부여할 수 있는 방법과 제한점도 예시하였다.

This paper proposes a new algorithm for estimating ARMA model parameters. In estimating ARMA model parameters, several methods such as generalized least square method, instrumental variable method have been developed. Among these methods, the utilization of a bootstrap type algorithm is known as one of the effective approach for the estimation, but there are cases that it does not converge. Hence, in this paper, making use of a cross correlation function and utilizing the relation of structural a priori knowledge, a new bootstrap algorithm is developed. By introducing theoretical relations, it became possible to remove terms, which is liable to include much noise. Therefore, this leads to robust parameter estimation. It is shown by numerical examples that using this algorithm, all simulation cases converge while only half cases succeeded with the previous one. As for the calculation time, judging from the fact that we got converged solutions, our proposed method is said to be superior as a whole.

Purpose: The purpose of this study was to examine the relationship between glucose control, diabetes self-care and depression in community dwelling older adults with type 2 diabetes mellitus. Methods: The cross-sectional survey data of 148 older adults at a senior center were analyzed in this study. We collected data on diabetes self-care, depression, and demographics by face-to-face interviews. Blood samples for HbA1C were obtained from the participants. Results: The average duration of diabetes for the participants was $10.6{\pm}9.31$ years. Fifty percent of the participants had HbA1c higher than 7.0% (mean 7.179%). The level of diabetes self-care was related to depression (r=-.225, p<.01). HbA1c was positively related with the duration of diabetes diagnosis (r=.224, p<.01). The only sub-dimension of diabetes self-care that was related to depression was exercise (r=-.307, p<.01). Conclusion: Only half of the community dwelling older adults with type 2 diabetes had an optimal level of diabetes control. Supported by the evidence, the longer the duration of diabetes since the initial diagnosis, the poorer the glucose control was. Identification and intervention for depression in people with diabetes should be considered to improve diabetes self-care, especially to perform more exercise.
