The stress analysis concerned with axisymmetrically loaded axisymmetrical structures, such as pressure vessels, rockets, cooling towers, roof domes and storage tanks, has been researched with a lot of difficulties. The elements of revolution using the finite element method enable these problems to be analyzed with a high degree of confidence. This research focuses on the efficient conduct of the thin axisymmetric shells subject to axisymmetrical load which was idealized by a series of conical frustum-shaped elements that was suggested by Grafton and Strome and later extended by Percy. In this study, this research mentioned above is extended to the conical shell whose end is fixed to simplify the methodology of the analysis of any kinds of axisymmetrically loaded axisymmetrical shell structures. To demonstrate the validity and simplicity, the results of the proposed method were compared with the numerical solution SAP90 and got agreeable results.

This study is to investigate general tendency of high school girl's consciousness of values in the family and household abilities, to identify their related variables, and to find the main variables affecting household abilities. Data was collected for 569 students. Through a structured questionnaire, data was analyzed by frequency distribution, percentage, mean, Duncan's multiple range test, and Stepwise Regression. Major findings are as follows : 1) The consciousness of values in the family of high school girls showed a modern tendency in general. 2) Most subjects showed medium level of household abilities(52.6 point out of a possible 100), proving to be relatively lower. 3) Household abilities of high school girls were influenced by the consciousness of values in the time management, household, and life satisfaction about family.

This study investigates the effect of mixing method on the antiwashout underwater concrete containing Fly Ash. On the experimental condition, the unit weight of used materials was fixed and a new the mixing method different from the traditional method in its prolonged mixing time and the order of material inputs was used. In this experiment, the mixing time was prolonged to 10 minutes, and the order of material input was changed to make the admixture homogeneous. That method of mixing improved the fluidty, the unit weight and compressive strength of fresh concrete.

농산물의 품질은 여러 가지 인자에 의해 결정되는데, 이 인자들은 파괴 또는 비파괴 측정방법을 이용하여 측정되고 검사된다. NIR분광분석법은 당도, 산도와 같은 내부품질을 측정하는데 이용되고 있다. 과일의 색. 크기와 같은 외부 품질 측정에는 CCD 카메라가 사용되고 있다. 오늘날 이러한 비파괴 검사법이 널리 연구되고 있다. 컵 위에 자동으로 탑재되어 카메라와 NIR장비로 실시간으로 측정된 과일의 품질과 등급은 내부, 외부인자에 의해 결정된다. 본 논문은 과일 선별기를 제작함에 있어서 과일의 칼라영상의 경계를 검출하는 수정된 윤곽선 추적법과 일반적인 방법보다 빠른 속도로 연결점 데이타를 구성하는 방법을 제안한다. 연결점 데이타는 과일 영상의 크기 계산과 하나의 컵에 중복 탑재 과일과 컵 사이에 불량 탑재된 과일을 검사하는데 사용된다. 설계된 과일 선별기는 귤의 경우 과일의 당도 산도 및 크기를 검사하면서 초당 8개의 과일을 선별할 수 있다. The quality of agricultural products is classified with various factors which are measured and determined by destructive and/or nondestructive method. NIR spectrum analysis method is used to determine internal qualities such as a brix and an acidity. CCD color camera is used to measure external quality like color and a size of fruit. Today, nondestructive methods are widely researched. The quality and the grade of fruit loaded into a cup automatically and measured in real time by camera and NIR system is determined by internal and external factors. This paper proposes modified boundary tracking algorithm which detects the contour of fruit's color image and make chain code faster than conventional method. The chain code helps compute a size of fruit image and find multiple loading of a fruit in single cup or fruit between two cups. The designed classification system sorts a citrus at speed of 8 fruit/s, with evaluating a brix, an acidity and a size grade.

Neurofibroma is benign neurogenic tumor originated from nerve tissue-Schwann cell, fibroblast, perineural cell. They have no sexual predirection and generally no symptom. Neurofibroma is classified to solitary type and multiple type and is rare in oral resion. They located in soft tissue of tongue, lip, palate and oral mucosa in form of sessile and pedunculated mass and are rare intraosseous region. In solitary type, complete excision is the choice of treatment due to their rare recurrence rate. In multiple type, the same is choice of treatment but bas some difficulty of plastic problem, bleeding

Purpose: The purpose of this study is to find a way to improve and overcome the psychological treatment limited to the negative factors dealt with in psychology from a positive psychological point of view. To this end, this study aims to verify whether a positive psychotherapy program can improve happiness, resilience, and post-traumatic growth along with improvement of psychological symptoms such as depression. Research design, data and methodology: To this end, in this study, mean difference analysis was conducted using t-test on 10 participants in the 16th PPT program and 14 in the control group. Also, after setting the main variables, we tried to confirm the effectiveness through simple regression analysis and multiple regression analysis of the causal relationship model. Results: As a result of the independent sample t-test and the paired sample t-test, it was confirmed that the group participating in the PPT program had higher flourish, happiness, resilience, post-traumatic growth, and lower depression. In addition, as a result of regression analysis, it was confirmed that post-traumatic growth had a positive effect, and that depression was a life-threatening factor. Conclusions: Since the PPT program has a positive effect on the participants with relatively negative psychological symptoms, it is necessary to expand it. In addition, it is necessary to introduce various preventive programs such as PPT as well as traditional psychological treatment for negative symptoms such as depression.
