경주 월성은 신라시대 궁궐이 있었던 역사적 상징성이 있는 궁궐터로 왕경 경주의 대표적인 역사유적이다. 본 연구는 경주 월성을 대상지로 역사공간 이미지와 관광객들의 이용행태에 대한 조사를 실시하였다. 연구방법은 주로 현장조사와 설문조사 두 단계로 실시하여 수집된 데이터를 행태, 시간, 공간별로 분석했다. 연구결과는 경주 월성의 주된 이용행태는 서서 하는 행위, 앉아서 하는 행위, 놀이/유흥 순으로 나타나고, 일반적인 역사문화유적지와 비교해 이용행태는 매우 단조로운 것을 알 수 있다. 경주 월성의 이용활성화를 위하여 주 진입로의 역할기능을 강화하면서 탐방객들을 월성 내 타 공간으로 분산시키기 위하여 각 동선코스를 사전에 안내하는 표지판, 야간조명, 식생정비, 도로정비 등을 필요하다.

Purpose: The purpose of this study was to explore and understand life and meaning in life of elementary school students. Methods: Data from 1,790 higher grade elementary school students were analyzed for content of meaning in life. Results: The students described the following: 1) Meanings of living existence included, 'living things', 'importance', 'human life', 'family', 'event', 'eternity', 'origin of life', 'disease', and, 'protection'. 2) Four categories were found for reasons why human life is important, 'solitary', 'limitation', 'valuables', and 'living'. 3) Things that one can do to protect the value of human life were, 'doing safely', 'keep things well', 'altruistic behavior', 'doing sound activity', 'preservation & development', and 'devotion of oneself'. 4) Meaning of life included 'to accomplish plans', and 'to do things' 5) Cases when students felt life had meaning were 'perform meaningful behavior', 'comfortable emotionally', and 'receiving help from others'. 6) The methods by which to live a meaningful life were 'working diligently', 'serving', and 'doing rightly'. Conclusion: These results suggest that students recognize the meaning of life in a most positive way and with a relatively wide scope, but as a few students had a negative orientation, age-appropriate and more systematic education programs are needed.

The annals of Joseon Dynasty is one of the UNESCO's Memory of the World Register. For the safety preservation of wax applied volumes of the annals of Joseon Dynasty, the aging behavior of beeswax and beeswaxed Hanji with $CO_2$, $O_3$, $SO_2$ and $NO_2$ gas has been evaluated. The weight loss of beeswaxed Hanji after aging under ozone gas were increased because of strong acidity of ozone. The acid value and relative intensity of carbonyl groups in beeswax were stabilized with aging time. The physical strength of dewaxed Hanji after ozone aging were rapidly decreased by aging time. The crystallinity of dewaxed Hanji were stabilized at all aging times.

The development of science and technology not only improved the quality of life of human being, but also brought about environmental problems. Consequently, consensus has been established that early environmental education for youngsters is critical for the preservation of clean environment. A conventional way of teaching has not been very effective for changing their attitude and behavior regarding environmental problems. STS program, which has been one of the major trend in science education, intends to teach science through everyday experience rather than knowledge. This study purports to examine the effectiveness of STS program on environmental problems compared to conventional teaching method. Six week program was developed and applied to subchapter 'Environmental Pollutions & Our Lives' of 3rd grade middle school science text book. The results of this study can be summarized as follows. 1. STS program was significantly effective in changing students' attitude(p<.001). It was effective not only changing their thinking but also changing their behavior. 2. There was no difference between the STS program and conventional teaching method in improving students' knowledge(p>.05). 3. The correlation between the level of knowledge achievement and the attitude on environment was very low(r=.0564,p>.05).

본 연구는 청소년의 환경친화적 의복 소비행동에 영향을 미치는 변수들을 파악하여, 환경친화적 의복 구매, 사용, 처분행동을 유도하기 위한 교육적 자료를 제공하는데 목적이 있다. 연구 결과는 다음과 같다. 첫째, 청소년의 환경활동 경험은 보통 이상이며, 환경활동 경험 중 환경문제에 대한 교육을 받은 경험이 가장 낮게 나타났다. 둘째, 환경친화적 가치관 중 환경보전 가치관이 가장 높게, 이타주의 가치관이 가장 낮게 나타났다. 셋째, 의복을 통하여 개성을 추구하고자 하는 욕구가 가장 크고 다음으로 편안함과 가격을 추구했으며, 유행과 브랜드를 추구하는 성향은 낮은 것으로 나타났다. 넷째, 환경친화적 의복 소비의식 중 처분의식은 보통 이상이나 구매의식과 환경문제 인식은 보통 이하로 낮게 나타났다. 특히 의복이 유발하는 환경문제에 대한 인식이 가장 낮은 점을 감안해 의복의 생산과 소비과정에서의 환경오염과 이를 예방할 수 있는 방안에 대한 교육이 필요하다. 다섯째, 환경친화적으로 의복을 소비하는 행동은 전체적으로 낮게 나타났다. 하위요인 중 사용과 처분 행동은 어느 정도 실행되나 구매 행동은 환경친화적으로 이루어지지 못하고 있었다. 이는 그동안의 환경교육이 주로 자원 절약과 재활용 등 사용 및 처분행동에 초점을 맞추어 진행되었기 때문으로 생각되며, 따라서 앞으로는 소비의 시작인 의복의 구매단계에서 환경친화적인 소비행동을 할 수 있도록 교육해야 할 것이다. 여섯째, 청소년의 환경친화적 의복 소비행동에 영향을 미치는 변수 중 가격 추구 성향과 의복 처분의식은 의복 구매 사용 처분의 모든 의복 소비행동에 영향을 미치는 것으로 나타났다.

The purpose of this study is to make planning factors for outdoor space in elementary school site, with analyzation focusing on a Japanese elementary school examples. We evaluated the planning factors which encourage the development of children’s behaviors from quality of space. And we can get the important points as planning factor for school site as follows: 1) The base point of zoning is school building, building entrance, entrance of site and track 2) The importance of linked space plan with inside of site and surrounding environment 3) Preservation linked system of space in school site for linked pattern of child’s behavior.

The purpose of this paper is to introduce the concept of strongly extending modules which are particular subclass of the class of extending modules, and study some basic properties of this new class of modules. A module M is called strongly extending if each submodule of M is essential in a fully invariant direct summand of M. In this paper we examine the behavior of the class of strongly extending modules with respect to the preservation of this property in direct summands and direct sums and give some properties of these modules, for instance, strongly summand intersection property and weakly co-Hopfian property. Also such modules are characterized over commutative Dedekind domains.

The processes of formation and dissociation of gas hydrates were investigated by monitoring pressure and temperature variations in a pressure cell in order to understand the kinetic behavior of gas hydrate and the controlling factors fur the phase transition of gas hydrate below freezing. Gas hydrates were made kom guest gases ($CH_4,\;CO_2$, and their mixed-gas) and fine ice powder. We found that formation and dissociation speeds of gas hydrates were not controlled by temperature and pressure conditions alone. The results of this study suggested that pressure levels at the formation of mixed-gas hydrate determine the transient equilibrium pressure itself.

In this paper the projective controls, previously derived to preserve the dynamic modes of a state-feedback reference system, are extended to allow the preservation of the modes of a general output-feedback reference system. In general, the extension allows projective controls to be used as a controller approximation technique, where a reduced-order controller is designed to approximate the closed-loop behavior of the higher-order reference controller. This extension is useful if the best available reference control for the system is an output-feedback control. An example shows that the increased design freedom of proposed design method allows the stabilization of a given plant using a lower-order controller than the projective controls with state-feedback reference.

The annals of Joseon Dynasty is one of UNESCO's Memory of the World Register. For the safety preservation of the waxed annals of Joseon Dynasty, the acidic and alkaline aging mechanism of beeswax and beeswaxed Hanji has been investigated. The weight loss of beeswaxed Hanji by the acidic aging was higher than those of alkaline beeswax. The acid value and relative intensity of carbonyl groups in beeswax were slowly increased with aging time. The strength of dewaxed Hanji was decreased with aging time. The significant changes of crystallinity of dewaxed Hanji by acidic and alkaline aging were not observed.
