본 연구는 토마토의 도장 억제를 위하여 보다 안정적인 건묘를 생산하고자 육묘 기간 중 diniconazol 처리시기 처리농도에 따른 경엽처리와 침지 시간에 따른 종자처리가 묘 도장 억제에 미치는 영향을 알아보고 적정 방법을 구명하고자 수행하였다. Diniconazol 처리시기 및 처리농도에 따른 토마토의 초장 신장을 본 결과 1단계 2단계 3단계로 초장의 신장과 절간장 억제가 잘 나타났다. 이는 이른 시기가 늦은 시기보다 식물체가 받는 약제의 양이 더 많기 때문에 약제 효과가 잘 나타났다. 1단계는 4절, 2단계, 3단계는 각각 3절, 2절로 억제된 절간수가 줄어들었다. 약제 지속성이 초장의 신장에 미치는 영향을 본 결과 1단계, 2단계 $5mg{\cdot}L^{-1}$은 약제 처리 후 초장의 신장억제가 나타났으나 다른 처리구에 비해 일정한 시간이 지나면 빨리 회복하는 경향이 나타났다. 3단계에서는 초장 신장 억제 기간이 짧았고 빠른 회복을 보였다. 1단계는 5주, 2단계, 3단계는 각각 4주정도 약제 지속효과가 나타났다. 육묘 종료 후 정식한 결과 생체량이 빨리 증가 되어 생육에는 무처리와 유의차가 없었다.

The study was done to improve the job training course for Community Health Practioners (CHPs) by evaluating the level of help that the training provided to the CHPs in carrying out their work and to analyze the management activities of the CHPs in order to develop a more effective CHP training program. The methodologies used in the study were a questionnaire survey. The survey results were analyzed using SPSS Windows. The study results are as follows. 1. The total average level of help from the job training(Theory. Practice and Field Practice) for carrying out the CHP work was found to be $3.04\pm.53$ (of a possible 4), which indicates a high level of help. The average for clinical practices was $3.16\pm.60$. for theory. $3.11\pm.40$ and for field practice. $2.84\pm.60$. 2. For the theory content of the job training courses. the help level was low in the area of mother and child health management/family planning with an average of $2.65\pm.62$ and in the area of health information system development with an average of $2.62\pm.83$. The reason for these deficiencies were. in order of frequency. few opportunities to apply learning. training content that was inadequate. training methodologies which were incongruent with content. improper training items and insufficient class hours. For the practice. the clinical work in rehabilitation/orthopedics departments and in ENT/Opthalmology departments had averages of $2.96\pm.86$ and $2.97\pm.80$ respectively. This low level resulted from the lack of direct experience. lack of sincerity during the practice time. lack of practice guidance. insufficient time and lack of practice equipment. in that order. For the field practice. the delivery management averaged $2.06\pm.90$ as the lowest help level. In this case 68% of respondents replied that there were no relevant reasons for this deficiency. 21% responsed that there was a lack of direct experience, 7%, a lack of practice guidance and 4.8%, insufficient time. 3. There were significant differences for several demographic variables when comparing the help level of the clinical courses (practice and Field Practice). A higher help level was reported by older nurses as compared to younger ones, experienced nurses as compared to scholarship nurses, and married over single. Also for nurses who had finished more other programs and were qualified or licensed in several areas the level was high. Although it was not statistically significant the level was higher if the work area was in a rural county, not a city, and if one had more recently completed the job training(P<,05). 4. Of the respondents 58.6% replies stated the period of job training for the CHP was adequate, but 51.7% reported that the period for theory courses was too short while an other 48.3% responded that it was sufficient. For practice locations, 50% responsed that it was good to practice in medical institutions(primary, secondary and tertiary) at the same time. While 48.3% agreed that doing theory and practice simultaneously was good, and 56.9% agreed that field practice should be done after completing theory and practice training. Hence, the development of new field practice guidelines suitable for changing environments of health management are required in place of the existing ones which were considered low in help level to the practical work of the CHPs.

센서 네트워크는 빛, 소리, 온도, 움직임 같은 물리적 데이터를 센서 노드에서 감지하고 측정하여 중앙으로 전달하고 처리하는 구조를 가진 네트워크이다. 센서 네트워크는 여러 분야에서 활용할 수 있는 기술이다. 센서 노드가 외부에서 채취한 데이터를 실시간으로 사용자에게 전달하는 것은 매우 중요하다. 센서 네트워크의 핵심은 센서 노드인 하드웨어 플랫폼과 노드에 들어가는 초소형 운영체제라고 할 수 있다. UC 버클리에서 개발된 TinyOS는 센서 노드에서 동작하는 운영체제 중 가장 많이 사용되고 있다. TinyOS는 Event-driven 방식이며 Component 기반의 센서 네트워크 운영체제이다. 기본적으로 비선점 방식의 스케줄러를 사용한다. 만약 급한 작업이 수행되어야 하는 시점에서 다른 태스크가 수행 중에 있다면 수행 중인 태스크가 완료할 때까지 기다려야 한다. 이러한 특성으로 인해 TinyOS에서 정해진 시간안에 자신의 작업을 끝낸다고 보장하기 어렵다. 최근 연구에서 TinyOS의 빠른 반응성을 위해 Priority Level Scheduler라는 선점 기능이 제안되었다. 이것은 제한적으로 5개의 우선순위를 만들어 높은 우선순위가 낮은 우선순위를 선점할 수 있게 한다. 여기서 본 논문은 TinyOS의 실시간성을 보장함과 더불어 사용자 태스크의 평균 응답시간을 줄이고자 Priority Level Scheduler에 실시간 스케줄러인 EDF(Earliest Deadline First)를 적용한 선점형 EDF 스케줄링 방식을 제안하고자 한다.

All the forces in the real world act dynamically on structures. Design and analysis should be performed based on the dynamic loads for the safety of structures. Dynamic (transient or vibrational) responses have many peaks in the time domain. Topology optimization, which gives an excellent conceptual design, mainly has been performed with static loads. In topology optimization, the number of design variables is quite large and considering the peaks is fairly costly. Topology optimization in the frequency domain has been performed to consider the dynamic effects; however, it is not sufficient to fully include the dynamic characteristics. In this research, linear dynamic response topology optimization is performed in the time domain. First, the necessity of topology optimization to directly consider the dynamic loads is verified by identifying the relationship between the natural frequency of a structure and the excitation frequency. When the natural frequency of a structure is low, the dynamic characteristics (inertia effect) should be considered. The equivalent static loads (ESLs) method is proposed for linear dynamic response topology optimization. ESLs are made to generate the same response field as that from dynamic loads at each time step of dynamic response analysis. The method was originally developed for size and shape optimizations. The original method is expanded to topology optimization under dynamic loads. At each time step of dynamic analysis, ESLs are calculated and ESLs are used as the external loads in static response topology optimization. The results of topology optimization are used to update the design variables (density of finite elements) and the updated design variables are used in dynamic analysis in a cyclic manner until the convergence criteria are satisfied. The updating rules and convergence criteria in the ESLs method are newly proposed for linear dynamic response topology optimization. The proposed updating rules are the artificial material method and the element elimination method. The artificial material method updates the material property for dynamic analysis at the next cycle using the results of topology optimization. The element elimination method is proposed to remove the element which has low density when static topology optimization is finished. These proposed methods are applied to some examples. The results are discussed in comparison with conventional linear static response topology optimization.

The present study is aimed to reconsider the time of installation and the purpose of the square footstone located at the center of the wooden pagoda in Hwangnyongsa Temple, based on related precedent studies. Precedent studies are divided into two streams of assertions: one is that the square footstone was to support the major pillars at the time of building and the other is that it was installed to store Buddhist reliquaries inside the central foundation stone after the wood pagoda burnt down in the Invasion of Mongol. Summarizing the grounds with which the precedent studies support their assertions, they are the relation with Gaseopbul Yeonjwaseok, the emerging time of the square footstone, repairing work at the level of reconstruction, additional enshrinement of general Buddhist reliquaries and so on. The present study reviewed the key grounds suggested in the previous studies regarding the square footstone. First, it was determined that the square footstone has nothing to do with Gaseopbul Yeonjwaseok, after looking into the timings of appearance, condition and shape in literatures. Rather, it was assumed that Gaseopbul Yeonjwaseok resembles a stone column. Next, the square footstone is assumed to be installed after the 4th year of King Kwangjong's rule because the wood pagoda was lost in fire in the 4th year of Kwangjong's rule and it had been left alone for 68 years until the repair work finished in the 13th year of King Hyunjong. It is assumed that repair works at the level of reconstruction had been twice in total, say, once during King Kyungmun and Hyunjong, respectively. Next, looking into the establishment of the general Buddhist reliquaries and the repair work during King Kyungmun, it was not common then to enshrine additional Buddhist reliquaries when repair work progressed and so there was not an additional enshrinement of Buddhist reliquaries after King Kyungmun. However, it is hard to decide that there was no repair work at the level of reconstruction at that time. Last, we can find a similar case to the square footstone of the wood pagoda in Hwangnyongsa Temple in the copper pagoda in Japanese Yaksasa Temple. In conclusion, it is assumed that the wooden pagoda in Hwangnyongsa Temple was lost to the fire in the 4th year of King Kwangjong's rule and thus the square footstone had been used as Jinho stone to protect Buddhist reliquaries and used as a propping stone for the major pillars after King Hyungjong.

An on-going creative process was the major principle of Kantor's artistic endeavors. Kantor's emphasis on process grew out of his frustration with the experience of creation being isolated from the audience in the present time, during the moments of encounter. At the same time, however, Kantor was always aware of the fact that the first night of each and every performance that he made was the last point of his creative intervention. Despite being performed live in the present time, Kantor saw theatre essentially as an end product. This does not mean that Kantor abandoned the concept of on-going process, for process was for the artist a means to reject the idea of a finished work of art and to denounce the feeling of satisfaction derived from the traditional denouement in representational theatre. For him, theatre that dominated his time isolated the audience from the art work and the artist, and from this perspective his continual emphasis on process should be understood as an aesthetic principle in order to open up and expand the dimension of art into the realm of the spectator so that the experiences of both the artist and spectator may coexist. The heaviest barrier that separated the artist and his work from its audience was the creative structure that governed Western art. In theatre it was the dramatic structure that was the main object of his series of severe challenges. Not only did it fail to represent reality but it distorted reality, creating nothing but artificial illusion. Under this condition, all that was permitted to the audience was mirages. However, Kantor never completely discarded illusion from his theatre. The point for him was always to created a circumstance where the illusory reality of drama comes to exist within the dimensions of our reality. It was Kantor's belief that instead of a total denial of illusion, his theatre should strategically accommodate illusion which comes from reality. And, the aim of Kantor's theatrical experiments was to invite the audience into this ambience and transform the experience of his audience into a much more participatory one. This paper traces the ways in which Kantor transgressed the dominating conventions of representational, literary theatre, and how such attempts induced an alternative mode of spectatorship. The study will begin from an investigation into Kantor's attitude towards illusion and reality, and then move onto a closer inspection of how he spatially and dramaturgically materialized his concepts on stage, giving special focus on Wielopole, Wielopole.

The past and present time are consistent thinking process system which composed of single concept not separated concept. It's common concept for interior designer to how to realize the thinking process system in actual present day. So this paper was focused on purpose of establishing for procedural process theory by approaching typological process system in interior design process. Interior design being composed of typological thinking process system has been headed as a critical issue to how to transplant well between the design and typological objects. Also we have to be needed to know for the process of visual expression and verbal ability to be able to extract the designer's elements from it. Through the process of visual expression and verbal ability to be able to extract the designer's elements from it. Through the process of visual transformation and analysis we have to extract concepts with united design objects. From these process it should be followed adequate adjudgment on the extracted fragments' assembly and dissociation methods through physical limitation of elements functionality and feasibility's measurements. Therefore from the morphological designed results reflected to typological concepts finished material detail and texture we should be able to take the integrated thinking process system. Lastly interior designer should be able to check whether it was best choice from the consistent design feedback process to ask whether it contains the conceptual design process and new typological objects without non-conformity between past and present days in interior space. Now we should be asked for development of practical design process to be able to realize above assumptions called "Development and Suceeding of Cultural Value System'. Additionally, we have to continue to develop for our true meaning of interior design process, not repetition of past's imitation.tion.

Objectives : This study is aimed to seek how to promote oral health care by leading the clients with dental fears to change their behaviors in oral hygiene care based on the analysis of the relationships between the dental fears and oral health care behaviors of the clients who visit the Dental Hygiene Education Room. Methods : This study analyzed the 361 dental hygiene records of the subjects with finished treatment and accurate records among a total of 370 clients who had received dental hygiene care at the Dental Hygiene clinic in Y University from March 2007 till June 2009. According to their general features, the study analyzed whether they had any dental fears and why such fears occurred and conducted Chi-square test to compare their oral hygiene care experiences and behaviors with dental fears. Data analysis was made using the SPSS 12.0K for Window, with level of significance set at 0.05. Results : 1. In terms of dental fear or non-fear, the comparison by gender showed that women had a higher level than men, with 76 women(47.2%) answering yes; the comparison by age showed that the age group of 30 years old or older had a higher level than other groups. 2. In terms of dental fear reasons, "the past pain experiences" recorded 34.2%, showing the highest rate. 3. In addition, dental fears had influences on regular dental examination, scaling and dental hygiene education and the subjects without dental fear showed higher levels in terms of tooth-brushing frequency and time. Conclusions : To control "the past pain experiences", future dental treatment should place priority on preventive treatment and get clients to cope with pains through the preliminary education with pains. Besides, to make an effective oral health care of the clients with dental fears, dental hygienists should control the fears of the clients and perform an appropriate oral health care for them using the communication techniques to make friendly and trustworthy impressions.
