This research, on the basis of recognition on the seriousness of juvenile drop-outs and the social problems resulted from it, intends to compare the differences between students in alternative school (drop-outs students) and general school (in-school students) on home growth environment, career decision-making difficulties and career decision-making. By doing thus, it will be able to widen the breadth of understanding of the drop-outs. Dropping-out means not only those drop-outs have limitation in choosing their future as an individual, and are exposed to social risks, but also they are thrown away without having any means for social protection. Therefore, the problems of drop-outs from school are not restricted to the educational area. It is possible that it also raises many social problems by bringing vicious cycles of in-adaptation to the society. The followings are the intended research items. 1. Are there any differences in home growth environment between alternative school (drop-out) and general school (in-school) juveniles? 2. Are there any differences in career decision-making between alternative school (drop-out) and general school (in-school) juveniles on home growth environment ? To achieve these purposes, we used questionnaire, and surveyed 133 students in alternative school and 660 students in general school (total 793 students) in Busan. For this study, we used the tools that they are career decision-making scale, decision-making scale and home growth environment scale. The collected data are analyzed by SPSSWIN(Statistical Package for Special Science/ for WINDOW) 10.0 program The results of this study were as follows ; They are confirmed that the lower elements of career decision-making difficulties, career decision-making and home growth environment have all static co-relation, and home growth environment, career decision-making difficulties and career decision-making have mutual supplementary relativity and also have mutual influence on each other. they are confirmed that home growth environment plays a key role in the formation of career decision-making and career decision-making difficulties. Above all, the prevention of the phenomenon of juvenile dropping-out is important and it can be begun from family. To make suitable circumstances for juveniles to grow up forming desirable career decision-making and career decision-making difficulties, they are needed that their parents and community should do their best together, networking tightly to prevent the anticipatable problems to juveniles from happening.

허재영 仁濟大學校 大學院 2004 국내석사

어떠한 시스템이라도 오류는 발생할 수 있다. 사소한 오류라도 실제 시스템에 치명적인 영향을 미칠 수 있으므로, 오류 검출은 반드시 필요하다. 본 논문에서는, 전자 자카드 시스템에 적용될 수 있는 실시간 오류 검출 시스템을 개발하고자 한다. 자카드는 직물을 제직할 때, 경사를 조정하여 무늬천을 만드는 장치로 기계식과 전자식 자카드가 있다. 전자식 자카드는 기계식 자카드에 비해 생산속도의 증가 및 다양한 직물의 제직을 가능케 함으로써 현대 섬유산업을 한 단계 더 발전시키는 역할을 하고 있다. 그러나 전자 자카드의 경우 자카드의 동작을 전기적 신호로 제어하므로 가동 시에 발생하는 열 또는 데이터 전송과정에서의 잡음으로 인한 잘못된 데이터에 의해 직물이 잘못 제직되는 문제점이 있다. 본 연구에서는 전자 자카드의 오류를 실시간으로 검출할 수 있는 실시간 오류 검출 시스템을 PC 기반 내장형 시스템 구조로 개발하였다. 전자 자카드로부터 전송되는 디자인 데이터를 실시간으로 메모리에 저장한 다음, 원시 디자인 파일 데이터와 동기화시켜 비교하여 오류를 검출하였다. 전자 자카드의 디자인 데이터를 실시간으로 검사하여, 오류를 검출함으로써, 잘못된 디자인 데이터 전송에 의해 직물이 잘못 제직되는 문제점을 미리 감지하여 제직시 활용함으로써 전자 자카드의 제직 오류를 낮추어 생산 효율을 증대시켰다. Any system has the possibility of an error occurrence. Even if trivial errors were occurred, the original system would be fatally affected by the occurring errors. Accordingly, the error detection must be demanded. In this paper, we developed a real-time error detection system would be able to apply to an electronic jacquard system. A Jacquard is a machine, which controls warps while weaving textiles, for manufacturing patterned cloth. There are a mechanical Jacquard and an electronic Jacquard. The electronic Jacquard is better than the mechanical Jacquard in view of the performance. But, the problem of wrong weaving from error data exists in the electronic Jacquard. This problem occurs by the generated heat in operation or by the induced noise in data transfer, as long as electrical signals control of the behavior of a Jacquard. In this research, a real-time error defection system for an electronic Jacquard is developed for detecting errors in an electronic Jacquard in real-time. The real-time system is constructed to be PC-based embedded system architecture. The system detects the occurring errors in real-time by comparing synchronously transferred data from Jacquard with data in a design file. The information of detected errors are monitored to the screen and stored into a file in real-time as the outputs of the system. In this research, we solve the problem of wrong weaving through checking the weaving data and detecting the occurred errors of an electronic Jacquard in real-time. As a result, the occurrence rate of weaving errors decreases and the weaving productivity increases.

In this study, a simulation based mobile satellite antenna design process has been established. This design process includes a virtual prototype of the satellite antenna obtained from 3D CAD model. A virtual prototype model of a mobile satellite antenna consists of 3-axis controlled actuators to target a fixed satellite and to stabilize a antenna dish from ship motion. In the First stage, a full satellite antenna geometry model is created through a ProEngineer(Wildfire) 3D CAD modeler, in order to obtain physical characteristics, such as mass centers and moment of inertias. In this stage, collision detection of the CAD model has been also checked using ProEngineer. In the second stage, inverse dynamics simulations are carried out to determine the appropriate motors for antenna actuation, using ADAMS program which is a commercial multibody dynamic analysis code. In the third stage, to check the control algorithm of the virtual prototype model with base motion, ADAMS/Matlab Co-Simulation technique is used. Antenna plant model is created with ADAMS, and the control algorithm is implemental with Matlab/Simulink. The satellite antenna dynamics and control simulations with 5 different ship motions are carried out to see the performances of the proposed PIDA control algorithm. The proposed simulation based design procedure is expected to be applied for other robotic system design.

허재영 조선대학교 2010 국내석사

Recently, a military organization of our country has a change of perception and a cultural innovation among soldiers. As a result, human rights of the soldiers have improved and the soldiers have escaped from the old -fashioned barracks, but they have various problems. Among the problems, it is a representative that the soldiers failure to adapt to the military organization, for example, GP shooting happened recently. This study relates to a development of  welfare programs which are practical for the maladjusted soldiers. The development of programs is accomplished on the basis of analyzing a culture or a model for the development, which follows understanding of a concept on the military organization. This study presents a type of the accidents such as firearms and explosives-related accidents, leave a service, suicide, etc. which are based on the accidents happened recently in the military organization and prevention activities for the accidents. In addition, this study presents suggestions for the development in a management and a system of welfare programs by analyzing problems on the management and the system of programs which are currently performed. First, a suggestion for the management of the programs is to improve a screening system so as to provide the subject manager with the expertise. The screening system must be effected separately divided into a military experienced sector and a private sector a principle. But  benefits of both sectors should be kept. The private sector is easy to access to the maladjusted soldiers and has a great deal of basic knowledge needed for practice throughout studying and learning about the welfare for a long time. For the military experienced sector, it is easy to access to the military organization and to catch the problems on the existing system and thus, has advantage  to serve as a foundation in a system for correcting the problems . Accordingly, it is worth to take advantage of an academic study of welfare and a particularity of the military organization in harmony. Second, a suggestion for the direction of development in the management, it is required for a skill for the management that is a practical and can be easily joined in, not for a formal rather and goal-oriented perspective. Currently the welfare program does not guarantee using anonymity to participate in the program, and results in a problem being self-branded. It does not meet a purpose of the program to prevent the problems and also, causes a problem called “stigma”. As a result, for the management of the program, we should remove a factor of the “stigma” for the participation of the soldiers from the program by approaching it with an educational concept rather than a therapeutic concept. In addition, it requires for a change in the managing principals which needs to increase its effectiveness by reducing a heavy task and by focusing on the welfare service. Third, a practical program is presented by correcting the problems on the management and the system. The program has a significance in that the soldiers who are maladjusted and function in adverse to the organization goals try to improve their interpersonal skills so as to promote positive relationships between the closet colleagues within the organization, and thus, preventing an emergency of the maladjusted soldiers. A characteristic of the program for improving the relationship is focused on the individual’s self-growth and through group dynamics and processes, providing an opportunity to take care of himself and offering a structural framework for searching of their interpersonal relationships. This program is to specifically search for an experience on the interpersonal relationship in a personal past and present as well as group dynamics of the interpersonal relationship on which a general discussion in the group is emphasized, enhancing self understanding there through. That is, we understand a pattern on the interpersonal relationship that ever maintained in order to understand a type of a person’s relationship between the others at present, explore how to respond to the complicated problems of some conflicts, expectation, request, etc., and form a personal experience by opening their own consensus, and, further examine a more appropriate approach Finally, if we apply a practical welfare for the soldiers maladjusted in the military organization to the soldiers who are not adapted for the military services, it is judged that we could be attained better successful achievement than the welfare program performed past. Above all, it can be derived from survey results that the maladjustment for the military service is caused mainly by the interpersonal relationships that are conflict with their senior soldiers, and I have presented a novel program centered on the interpersonal relationships as a practical plan thereto. This program relating to a self-identity can be called a creative course in which one realizes a current situation which is placed through an interaction between one and the others, and designs in one’s future. Therefore, introduction of the above program into each military unit can be great helpful program for the maladjusted soldiers therein.

Analysis of enzymatic and microbial community in soil for biomarker from environment-friendly organic farming

허재영 경상대학교 대학원 2008 국내석사

Present day in agriculture, environment-friendly organic farming has received increasing attention and is used as substitutes for chemical fertilizer. The research on the agricultural usefulness of organic fertilizer that can enlarge production amount will make a steady progress. In this experiment with chinese Cabbage we analyzed the relationship between soil physical-chemical properties and cabbage production. For biological properties, we did microbial population analysis in soil through the plate count that has been used generally and the fatty acid methyl esters (FAMEs) analysis that can analyze the fatty acid of microorganism. We found pH of the soil with chemical fertilizer was lower than that of the soil with control and organic fertilizer treatment, and organic matter amount of the soil with chemical fertilizer was higher than that of the soil with control and organic fertilizer treatment. Cabbage's production in the soil with chemical fertilizer treatment and organic fertilizer treatment increased compared to control soil. Estimation of microbial diversity in soil, as a whole interrelation was shown in treatment and from early stage to next stage generally it was decreased and was tend to increase in harvesting from all treatment. Enzyme activity of microbe's in soil was found depend on microbial diversity which intern depended on using organic fertilizer. Therefore, the amount of various enzyme that microbe's secreted had an direct effect on bringing-up soil's quality. In future it is necessary to develop biomarkers for safe and environment-friendly farming. 최근의 농업은 친환경 유기농법에 대한 관심이 높아져 화학비료를 대체하면서 작물 생산량을 올릴 수 있는 유기질 자재의 농업적 활용과 개발에 대한 연구가 활발히 진행되고 있다. 이러한 연구는 토양복원을 목표로 행해지고 있으며, 지표는 토양의 건전성을 평가하여 판단할 수 있다. 토양의 건전성 평가는 크게 토양의 물리성과 화학성, 생물학적 특성 세 가지로 분류되는데 본 실험에서는 이 세 가지 중 생물학적 특성 중 미생물 생태 및 토양 효소활성분석을 통한 친환경 유기농법의 바이오 마크를 찾고자 실험하였다. 실험 작물로 배추를 이용하여 토양의 이화학적인 특성 및 배추 수량과의 관계를 분석하였다. 미생물학적 특성은 일반적인 분석방법인 플레이트 카운트와 미생물의 지방산을 분석하는 fatty acid methyl esters (FAMEs) 방법으로 토양 미생물의 분포를 조사하였다. 생화학적인 방법으로 효소활성 분석법으로 토양에 부착된 효소활성을 분석하였다. 본 실험의 결과로 첫째, 토양의 이화학적인 특성과 배추의 수량과의 관계를 분석한 결과 화학비료를 시용한 토양이 무처리와 유기질비료 처리구에 비해 pH가 낮아지는 것을 알 수 있었고 유기질비료 처리구에서는 토양 중 유기물 함량이 무처리와 화학비료 처리구 보다 높아지는 것을 알 수 있었다. 배추의 수량은 무처리에 비해 화학비료 처리구와 유기질비료 처리구가 수량이 높았으며 화학비료 처리구와 유기질비료 처리구간에는 별다른 차이가 없었다. 둘째, 플레이트 카운트를 통해 토양 중의 미생물 분포도를 분석 한 결과 처리에 따른 토양 미생물 다양성과의 상관적인 유의성은 나타나지 않았다. 이 결과는 토양 중에 존재하는 미생물은 0.1~1% 정도 플레이트 카운트로 분석 때문인 것으로 추정된다. 셋째, FAMEs 분석을 통한 토양 중 미생물 다양성을 평가한 결과 전체적으로 처리구간에 상관관계가 나타났으며 초기에서 중기로 진행 될수록 대체적으로 미생물의 다양성이 줄어들었으나 수확기에는 모든 처리구에서 높아지는 경향을 보였다. 본 시험 결과 친환경 유기농법의 바이오마크의 지표로 곰팡이 지방산 조성인 18:1 w9c가 될 수 있는 것으로 판단된다. 넷째, 토양에 부착된 효소 활성 분석 결과 유기질 비료 시용에 따른 미생물 다양성이 확보되고, 이로 인해 미생물들이 분비하는 효소들이 다양해지며 그 활성의 영향을 받아서 작물의 생육 및 토양의 건전성 등에 영향을 미친다는 것을 알 수 있었다. 이러한 결과들을 토대로 앞으로 토양의 생화학적인 건전성을 평가하기 위해서는 생물학적인 분석뿐만 아니라 분자생물학기법을 통하여 상관관계를 조사하는 것이 필요하다고 사료된다. 앞으로 친환경 유기농법에 대한 연구가 촉구되는 것을 고려할 때 보다 간편하고 효과적으로 평가할 수 있는 바이오마크 분석 및 개발이 필요한 것으로 사료되며 이 방면의 유사한 데이터들이 축적된다면 효율적인 지표로 사용할 수 있는 바이오마크 개발이 가능할 것이라 기대된다.

슬관절의 기능에 있어서 중요한 역할을 담당하는 반월상 연골판의 손상을 치유시키기 위하여 임상에서 흔히 사용되고 있는 3가지 봉합방법 즉 1) 수직봉합법, 2) 수평봉합법, 3) 고리봉합법의 일차적인 안정성을 비교하기 위하여 돼지의 외측 반월상 연골판을 이용하여 연골판에 일정한 손상을 만들고 3가지 방법의 봉합을 각각의 군에 시행한 다음 인장 검사기로 인장력 검사를 하여 다음과 같은 결론을 얻었다. 1. 수직봉합군(vertical suture group)이 평균인 장력 70.31 ±7.3N으로 3가지 방법중 가장 높았다. 2. 수평봉합군(horizontal suture group)은 평균인 장력 45.18± 15.3N을 보였으며 최저인장력 27.ON에서 최고인장력 68.6N으로 결과에 차이가 심했다. 3. 고리봉합군(knot-end suture group)은 평균인장력 19.0±6.2N으로 3가지 방법중 가장 낮았다. 4. 강선봉합사(stainless steelsuture wire)를 이용한 실험으로 평균 인장력은 수직봉합군이 184.1±21.6N, 수평봉합군이 41.7±13.7N이였으며 수직봉합군이 수평봉합군 보다 4.5배 높아서 훨씬 우수함을 알 수 있었다. 5. 본 실험 결과는 슬관절의 반월상 연골판 손상에 대한 봉합 치료에는 가능하면 수직봉합법을 사용해야 하며 고리봉합법의 사용은 신중해야함을 시사하고 있다. A biomechanical study on various suture techniques for torn meniscus was carried out in 45 lateral menisci of the hog knee which is closely similar to human knee. Longitudinal tear of the meniscus was produced and sutured with three commonly available methods, vertical, horizontal, and knot-end, and the primary stability of each specimen was tested with tensometer ( Instron, model No.1115, Kyowa, Japan). The mean value of tearing stress test was 70.31± 7.3N in the vertical suture group, 45.18 ± 15.3 N in the horizontal suture group with significant variation (minimum 27.0N to maximum 68.6N), and 19.o ±6.2 N in the knot-end suture group. This results indicated that the holding power of the suture is high in the vertical suture group and low in the knot-end suture group. An additional biomechanical test using a stainless steel wire suture showed that the mean tearing stress of the vertical suture and horizontal suture was I84.1 ± 21.6 N and 41.7± l3.7 N respectively, which showed that the stability of vertical suture was about 4.5 times stronger than that of horizontal suture. The above study has shown that for meniscus repair the vertical suture technique is most stable and should often be applied clinically, while the knot-end suture technique should be used with Precaution.
