Recently, functional insoles of wedge-type it is for the young to raise their height inserted between insole and heel cause foot pain and disease. Additionally, these have a problem with stability and excessively load-bearing during gait like high-heel shoes. In this study, we compared the changes in biomechanical characteristics of foot with different insole thickness then we will utilize for the development of the insole with the purpose of relieving the pain and disease. Subjects(male, n = 6) measured COP(center of pressure) and PCP(peak contact pressure) on the treadmill(140cm/s) using F-scan system and different insole thickness(0~50 mm) between sole and plantar surface during gait. Also, we computed changes of stresses at the foot using finite element model with various insole thickness during toe-off phase. COP moved anterior and medial direction and, PCP was increased at medial forefoot surface, $1^{st}$ and $2^{nd}$ metatarsophalangeal, ($9%{\uparrow}$) with thicker insoles and it was show sensitive increment as the insole thickness was increased from 40 mm to 50 mm. Change of the stress at the soft-tissue of plantar surface, $1^{st}$ metatarsal head represents rapid growth($36%{\uparrow}$). Also, lateral moments were increased over the 100% near the $1^{st}$ metatarsal as the insole thickness was increased from 0 mm to 30 mm. And it is show sensitive increment as the insole thickness changed 10 mm to 20 mm. As a result, it was expected that use of excessively thick insoles might cause unwanted foot pain at the forefoot region. Therefore, insole thickness under 30 mm was selected.

Cutaneous angiosarcorriias occur most commonly on the face and scalp of elderly individuals and are characterized by poor prognosis. We present a case of angiosarcoma in a 17-year-old boy not associated with any predisposing factors. The patient had three, ill-defined, 3 to 5 cm sized, erythematous, indurated subcutaneous nodules on the right upper extremity with a duration of 3 months. On histological examination, there were extravasated erythrocytes and irregular vascular channels lined by atypical endothelial cells in the dermis and subcutaneous tissue. The tumor cells appeared to dissect the collagen bundles. The patient was treated by wide surgical excision and post operative radiation therapy. However, 16 months after the operation, local recurrence was found to involve the close areas to the excision site on the right upper extremity and right axillary lymph nodes.

The flaw assessment method based on ${delta}_5$ parameter was recently proposed and put to the practical use. However: since it is almost impossible to measure the ${delta}_5$ by the existing commercial clip gager, we need to develope the specially designed gages which are suitable for that purpose. In this research, a double cantilever type ${delta}_5$ clip gage with the traveling distance of 4mm was developed by the finite element analysis and the construction of Wheatstone bridge circuit including strain gages. The linearity of developed ${delta}_5$ clip gage was evaluated by the MTS extensometer calibrator with the proper adapters which allow the 6s clip gage to sit on the calibrator. Consequently, the 6s clip gage revealed the good linearity between the output voltage and the traveling distance of gage.

In the present paper, flow and heat transfer characteristics of confined impinging slot jets have been numerically investigated using a SIMPLE-based segregated SUPG finite element method. For laminar jets, it is shown that the skin friction coefficient obtained from the present SUPG formulation approaches the grid-independent Galerkin solution inducing negligible false diffusion in the flow field when a moderate number of grid points are used. For turbulent jets, the k-$\omega$turbulence model is adopted. The streamwise mean velocity and the heat transfer coefficient respectively agree very well with existing experimental data within limited ranges of parameters.

Objectives: The purpose of this study is to obtain basic data on the development of a risk communication model through an investigation of risk perception for radon and identify effective risk communication channels. Methods: A questionnaire was used to evaluate differences in perception level according to respective communication channels. A chi-squared test was used to analyze the difference in pre- and post-risk communication by communication channel. One-way ANOVA was used to analyze the difference in the radon risk perception rate for each communication channel. Results: All of the communication channels resulted in increased radon risk perception, but there was no statistical difference between them in terms of perception (p>0.05). However, based on previous findings that it is effective to use a multi-channel approach, it is considered that communication channels based on duplicate avenues is most appropriate. Conclusions: It is expected that this study will be used as basic data to better understand the formation of public opinion about radon risk and to understand the social reaction to each risk factor.

설교비평을 통한 개혁주의 설교실습교육에 관한 연구

박태현(Park, Tae Hyeun) 한국개혁신학회 2016 개혁논총 Vol.39 No.-

그리스도의 복음을 설교하고자 훈련받는 신학생들은 교과과정 가운데 설교실습 시간을 갖는다. 설교실습은 신학전반과 설교에 관한 이론적 지식을 바탕으로 진행된다. 학생들의 설교 능력을 향상시키고자 애쓰는 교수들은 설교실습의 중요성과 필요성을 깊이 체감하고 있다. 본고는 이러한 교수들의 설교실습 시간을 위한 구체적인 모델을 제안하는데 있다. 그 모델은 개신교의 설교 훈련의 전통, 즉 종교개혁과 청교도들로부터 유래된다. 16세기에 교회의 개혁과 갱신을 위한 설교자 훈련 모임인 ‘프로페짜이’ 혹은 ‘설교연구 회’가 조직되어 운영되었다. 이 훈련 프로그램은 무엇보다도 목회자들 상호 간의 긍정적 비평과 조언을 통해 이루어졌다. 설교실습에 필요한 설교비평은 겸손한 마음으로 건덕을 세우고자 진행되어야 한다. 우리는 비평을 통해 건강한 성장을 꿈꿀 수 있다. 비평의 과제는 설교문 비평과 설교행위 비평으로 나누어진다. 무엇보다도 이 모델이 갖는 특징은 교수법의 관점에서 설교실습에 참여하는 학생들을 단순히 지도교수의 평가에만 의존하는 수동적 위치에 두는 것이 아니라, 학생들 스스로 설교 비평에 참여하여 자발적으로 학습하는 능동적 주체로 삼는다는 장점을 갖는다. 이 모델은 궁극적으로 학생들의 설교 실습의 효과를 높여 설교문 작성과 효과적 전달에 도움을 주는데 그 목적을 갖는다. 필자가 제안한 사용 가능한 구체적인 모델이 신학교에서 설교 훈련에 노력하는 모든 교수들에게 도움이 되길 기대한다. The theological students who are trained to preach the gospel of Christ have a preaching practicum class in their curriculum. The preaching practicum class is run on the basis of their knowledge about theology in general and preaching in particular. The professors who want to equip and enhance the students preaching capacity are deeply felt the importance and necessity of the preaching practicum class. This article intends to suggest a specific model for the preaching practicum class. The model traces back to a Protestant tradition of preaching practicum, the tradition of Reformation and the Puritans. In the sixteenth century the institution of Prophezei’ aimed for training preachers for the sake of church reform and renewal was organized and had a great success. This training program is above all based on the ministers’ positive criticism and advices for one another. The exercise of criticism necessary to the class should be conducted by a humble mind in order to strengthen the students preaching capacity. We can achieve a desirable growth through criticism. The task of criticism is divided into critic on sermon and critic on preaching act. Above all, in the view of didactic, the characteristic feature of this model does not leave the students simply to the professor s evaluation, but makes them to be involved in criticism and to be an active subject who learn voluntarily. This model has an ultimate purpose to equip the students both to write sermons and to deliver them effectively. The available and specific model that this writer suggest is hoped for useful to all the professors working for the preaching practicum class.
