This study is to examine various causes for generativity, explore the psychological and theological outcomes, and discuss new meanings of generativity, in order to enhance generativity of midlife Christian men. In this study, “The Loyola Generativity Scale”was administered on the random sample of 149 midlife men at age between 40 and 60 living in larger cities, with 12 Christian midlife men with higher scores of generativity than the random samples being selected as research participants. This study analyzed life-story of research participants through a spiral data analysis, which resulted in the following findings; the types and characteristics of the generativity in life-story of the research participants were expressed in the following five ways: sanctification-story, story of being the self, story of being the family, neighborhood story, and story of unity with nature. Focusing on the psychology of the generativity and mental health of Koreans from the perspective of pastoral counseling, the study has implications that it provides an integral understanding from theology and psychology on midlife men and an opportunity of growth and contributes to constructing healthy home and generativity society.

Recognition of sign has been studied to provide convenience tour information for foreigners and strangers through automatic recognition of sign. The sign image database is essential to training the classifier and to intuitive measurement of performance. In this paper, we described the sign image database collected at Jeonju Hanok Village. As to 45 each other sign image, corresponding 50 images are collected under several condition. This database could be important content to study for the field of pattern recognition. 간판인식은 관광지의 간판을 자동 인식하여 외국인 또는 외지인에게 편리한 관광 정보제공을 목적으로 연구되고 있다. 간판 인식 연구에서는 인식기의 훈련과 객관적인 성능 측정을 위해 간판영상 데이터베이스가 필수적이다. 이 논문은 전주 한옥마을을 대상으로 수집한 간판영상 데이터베이스에 대해 기술한다. 총 45개의 서로 다른 간판에 대해 각각 50개씩 영상을 다양한 조건에서 획득하였다. 이 데이터베이스는 패턴 인식 분야 연구를 위한 중요한 콘텐츠 이다.

특징 선택은 패턴 인식의 성능을 향상시키기 위해 부분집합을 구성하는 중요한 문제다. 특징 선택에는 순차 탐색 알고리즘으로부터 확률 기반의 유전 알고리즘까지 다양한 접근 방법이 적용 되었다. 본 연구에서는 특징 선택을 위해 양자 비트, 상태의 중첩 등 양자 컴퓨터 개념을 기반으로 하는 양자 기반 유전 알고리즘(QGA: Quantum-inspired Genetic Algorithm)을 적용하였다. QGA 성능은 전통적인 유전 알고리즘(CGA: Conventional Genetic Algorithm)을 적용한 특징 선택 방법과 분류율 및 평균 특징 개수의 비교를 통해 이루어졌으며, UCI 데이터를 이용한 실험 결과 QGA를 적용한 특징 선택 방법이 CGA를 적용한 경우에 비해 전반적으로 좋은 성능을 보임을 확인 할 수 있었다. Feature selection is the important technique of selecting a subset of relevant features for building robust pattern recognition systems. Various methods have been studied for feature selection from sequential search algorithms to stochastic algorithms. In this work, we adopted a Quantum-inspired Genetic Algorithm (QGA) which is based on the concept and principles of quantum computing such as Q-bits and superposition of state for feature selection. The performance of QGA is compared to that of the Conventional Genetic Algorithm (CGA) with respect to the classification rates and the number of selected features. The experimental result using UCI data sets shows that QGA is superior to CGA.

This study was designed to confirm the association between the pain of Tension-Type Headache(TTH) patients and their Oral Parafunction(OPF). Patients with TTH(n=58) visited the Department of Oral Medicine, Kyung Hee University Dental Hospital during two months were recruited to this study. 20 patients with OPF(bruxism, clenching, bruxism & clenching) are the experimental group and 38 patients without OPF are the control group. Both groups were asked to answer the questionnaire based on the diagnostic criteria of TTH(IHS). Then it was analyzed statistically.

Both groups were asked to answer the questionnaire based on the diagnostic criteria of TTH(IHS). Then it was analyzed statistically. 1. There was no difference in sex(p=0.91) and age(p=0.73) between two groups. 2. In the experimental group, dull pain was presented more frequently than in the control group. But, there was no difference between two groups(p=0.69). 3. In the experimental group, severe pain was presented more frequently than in the control group. But, there was no difference between two groups(p=0.40). 4. In the experimental group, pain shown bilaterally was presented more frequently than in the control group. But, there was no difference between two groups(p=0.52). 5. In the experimental group, pain was more increased by physical activities than in the control group. But, there was no difference between both groups(p=0.74). The pain of TTH patients with OPF was presented to be non-dull pain frequently and more bilaterally and severely, also increased more by physical activities than the pain of TTH patients without OPF. But, there was no significant difference between two groups. Therefore, it is considered that the pain of TTH is not influenced by OPF.

High information city has recently received much attention in the field of regional and urban planning as the means of a balanced regional development. The level of information in pusan lags for behind the National Capital Region and it faced the needs of the informational reorganization. According to the result of this study, high information urban in pusan area must be constructed on the outskirt and artificial-island. And it is desired to set up its plant of teleport, technopolis and marine industry.
