교통사고는 화재와 더불어 도시지역에서 발생하는 인위적 재해 중 가장 높은 비중을 차지하고 있어서 보다 과학적인 원인분석과 더불어 다양한 예방대책수립이 필요하다. 본 연구에서는 지방중소도시인 진주시를 대상으로 2013년 발생한 교통사고 데이터를 교통사고 발생 원인별 분석, 발생 시간 및 계절적 특성분석 등 위치정보와 연계하여 시공간적 분포특성을 분석하고 토지이용계획에 따른 도시공간개발 특성과 연계함으로서 교통사고와의 공간적 상관성을 분석하였다. 그 결과 사고유형별 사고 분포특성을 보면 측면직각추돌(차 대 차), 횡단중사고(차 대 사람)가 밀도분석과 최근린분석에서 가장 군집도가 높았으며, 중심상업지역과 고밀도 주거지역, 공업지역을 연결하는 도로상에서 가장 많이 발생하는 특성을 보였다. 또한 피해상황에서는 인적피해가, 기상상태에서는 맑은 날이, 노면상태는 건조할 때가, 도로형태는 삼지교차로 일 때가 가장 높은 군집도를 보여주었다.

This study was conducted to suggest the ecological restoration strategies for the disturbed landscapes by theoretical study. Especially, it is aimed to suggest three objectives for restoration by using native plants ; (1) prevention or reduction of wind and water erosion, (2) provision of food and cover for variety of animal species, (3) improvement of the visual or aesthetic quality of disturbed sites. The main results were summarized as follows. 1. Cooperation between restoration ecologists and restoration practitioners is needed to delineate a scientific approach to restoration ; (1) Being aware of published literature that describes similar work and/or establish general principles. (2) Preparedness to carry out proper experiments to test ideas. (3) Preparedness to monitor fundamental parameters in a restoration scheme. (4) Providing information about the behavior of species. (5) Publish results. 2. There are three models of succession in theories of plant succession. The tolerance and facilitation models were recommended to ecological restoration. The inhibition model applies in most secondary succession, but the actual species which are introduced first may inhibit the germination and growth of slower-growing species, or they may prevent the growth of other species whose propagules arrive later. 3. The objectives of erosion control, wildlife habitat provision, and visual quality improvement are not mutually exclusive. However, many revegetation practices in the past have emphasized one of these aspects at the expense of the others. 4. A native plant community can be the model of ecological restoration. By stylization/abstraction of native plant community, trying to learn the most essential characteristics of community types - environmental factors ; dominant, prevalent, and "visual essence" species composition - in order to use such information in restoration. 5. After developing mass/spaces plan, match plant communities to the mass/space plan. In utilizing community grouping, there needs aesthetic ability to understand design elements. 6. Several hydrophytes such as Pennisetum saccharifluous, Themeda triandra, Cirsium pendulum show relatively good germination rates. In case of mesophytes and xerophytes, Arundinella hina, Artemisia princeps, Oenothera odorata and legumes seem to have quick-germinating abilities at barren sites. Pinus thunbergii, Rhus chinensis, Evodia daniellii, Alnus firma and Albizzia julibrissin can be considered as "late succession" woody plants because they show low germinating rates and slow growing habitat. 7. The seeds used for restoration should be collected within a certain radius of where it will be planted. Consideration in genetic issues in the collection and use of germplasm can increase the odds for successful restoration efforts. 8. The useful model in the "drift" pattern occurs so abundantly in naturally evolving landscapes. As one species diminishes in density, a second or third species are increased. Thus, dynamic interactions between species are created. Careful using of "drift phenomenon" in planting was recommended. 9. Virtually no stand of vegetation today is immune from the introduction and/or spreading of exotic species. Therefore, the perpetuation of a restored sites requires conscious monitoring and management. Thus, management would be the most important process in ecological restoration. 10. In order to keep the sites "natural", alternative management strategies would be applied in management ; Atenative management strategies are decelerating successional process, accelerating successional processes or modifying species composition. As management tools, mechanical, chemical, biological or environmental factor manipulation, e.g., fire could be used.

조도가 고령자의 인지력에 미치는 영향을 연구하기 위하여, 온도 $25^{\circ}C$, 상대습도 50RH% 및 기류속도 0.02m/sec의 측정실에서 조도를 100lux, 300lux, 600lux, 1000lux 및 1500lux로 변화시키면서 고령자의 뇌파, 집중력, 심박동변이 및 진동 이미지를 측정하였다. 활동이 활발한 남성 고령자 10명을 피험자로 선정하였다. 측정 조건은 의자에 착석하여 안정을 취하고 있는 1met의 활동량으로 하고, 착의량은 약 0.7clo로 통일하였다. 측정 결과 고령자가 1000lux에 있을 때 미드 베타파가 66.35%가 증가했고, 슬로우 알파파는 31.57%가 증가된 것으로 미루어 고령자에게 1000lux가 가장 쾌적한 조도라는 것을 알았다. 또한 집중력은 100lux에서 보다 1000lux에서 8.83%가 증가했고, 집중력의 패턴도 균일하게 유지되었다. SDNN은 100lux에서 보다 1000lux에서 74.94%가 증가하였다. 신경과민은 100lux에서 보다 1000lux에서 97.23%가 감소되었다. 이외에도 1000lux에서 HRT는 뚜렷하게 증가되었고, 공격성은 현저하게 감소되었다. 따라서 고령자가 1000lux에 있을 때 쾌적성, 집중력 및 심장 안정도 등이 가장 높아지는 것을 기반으로 향후 노인복지시설을 설계하는 경우에는 무엇보다도 조도를 가장 우선하여 설계를 해야만 고령자들의 안전과 자립도를 높일 수 있다고 판단된다.

NATM (무근)터널의 라이닝 균열을 분석한 논문과 연계하여 NATM (철근)터널의 결함을 정밀안전진단 사례를 정리하여 결함별 원인을 분석하고자 하였다. NATM (철근)터널에서 콘크리트라이닝은 그 역할에 따라 철근과 같은 보강재를 사용하게 된다. 지반이 불량하거나 안전성 확보를 위한 라이닝 두께의 증가는 굴착단면의 증가와 라이닝 타설 물량의 증가를 유발하나, 철근보강 단면을 설계하여 경제성과 안전성을 함께 도모하게 된다. 시설물안전법에 의한 국내 1종 터널 시설물 중에서 NATM으로 시공된 구간에 철근보강을 실시한 라이닝의 결함 특성을 정리하여 형태별 발생원인을 분석하고자 하였다. 단철근, 복철근과 무근라이닝에 발생되는 균열을 비교하여 철근으로 인한 균열제어 효과를 분석하였다. 다양한 위치에서의 철근노출 사례와 함께 기술하였고 터널에서 고려될 수 있는 라이닝 두께 부족의 원인으로 정밀시공 미흡, 박락, 공용중 라이닝 화재에 의한 폭열, 지진, 용탈의 사례를 기존 연구와 비교하여 분석하였다. 향후 본 연구를 통해 정밀안전진단(터널) 세부지침의 보완 및 개정방향 등을 제시하고자 한다.

Geopolymer는 시멘트와 비교하여 $CO_2$ 배출량의 감소, 내화성, 낮은 열전도성 등 다양한 장점을 보유하고 있는 eco-friendly 건설재료이다. 그러나 표면에 화염을 가할 경우 geopolymer panel 표면의 열적거동에 대한 연구결과는 많지 않다. 본 연구에서는 내열성 건축자재로서 화염노출시 geopolymer 경화체의 표면특성을 조사하기 위하여 alumina 골재가 사용된 geopolymer 경화체 표면의 화염노출 특성에 대하여 조사하였다. 화염노출시 panel의 외형변형 및 열충격에 의한 크랙은 없었으며, calcite의 잔존량과 aluminosilicate gel의 halo 패턴으로 보아 화염에 의한 탈탄산 및 탈수는 표면에 국한되어 발생했으며, geopolymer 경화체의 내구성은 화염조사 후에도 유지되고 있는 것으로 판단된다. Quartz와 calcite가 감소함에 따라 gehlenite와 calcium silicate가 증가하는 경향을 나타내고 있으며, BFS의 치환량이 많을수록 현저하게 나타난다. 화염노출에 따른 미세구조의 변화는 탈탄산, 결정수의 탈수 등으로 기공의 형성과 발전되는 과정을 거쳐 calcium silicate, gehlenite 등과 같은 새로운 결정상의 형성에 의해 geopolymer panel 표면의 치밀화와 강화기구로 작용하여 내구성이 향상된 것으로 생각된다.

Bullets flying with a light from the back are called "tracers". Tracers are ignited by the combustion gas of the propellant and emit bright light that allows the shooter to visually trace the flight path. Therefore, tracers mark the firing point for allies to assist shooters to hit target quickly and accurately. Conventional tracers are constructed with a mixture of an oxidizing agent, raw metal, and organic fuel. Upon ignition, the inside of the gun can be easily contaminated by the by-products, which can lead to firearm failure during long-term shooting. Moreover, there is a fire risk such as forest fires due to residual flames at impact site. Therefore, it is necessary to develop non-combustion type luminous material; however, this material must still use the heat generated from the propellant, so-called "thermoluminescence (TL)". This study aims to compare the TL emission of Dy³⁺, La³⁺ and Ho³⁺ doped MgB₄O₇ phosphors prepared by solid state reaction. The crystal structures of samples were determined by X-ray diffraction and matched with the standard pattern of MgB₄O₇. Luminescence of various doses (200 ~ 15,000 Gy) of gamma irradiated Dy³⁺, La³⁺ and Ho³⁺ (at different concentrations of 5, 10, 15 and 20 %) doped MgB₄O₇ were recorded using a luminance/color meter. The intensity of TL yellowish (CIE x = 0.401 ~ 0.486, y = 0.410 ~ 0.488) emission became stronger as the temperature increased and the total gamma-ray dose increased.

아산만 해역에서 2005년 2월부터 6월까지 환경 요인과 플랑크톤 군집의 변화를 파악하고 이들 간의 상관관계를 파악해 보았다. 수온은 전형적인 겨울철과 봄철의 수온양상을 보였고, 염분의 변화는 크지 않았다. 식물플랑크톤은 2월에 만의 안쪽에서 첫 번째 peak를 보인 후 5월에 만 전체적으로 두 번째 peak를 보였다. 수온의 증가는 식물플랑크톤 우점종의 천이를 유발하여 2월의 식물플랑크톤 대증식기에는 규조류가 가장 우점하였으며, 5월에는 규조류와 은편모조류가 혼재하며 발생하였고, 6월에는 와편모조류가 우점하였다. 일반적으로 연안해의 식물플랑크톤 대증식은 봄철과 가을철에 발생하는 것으로 알려져 있으나 아산만 해역에서는 이보다 약 한달 정도 빠르게 발생하는 것으로 나타났다. 또한, 식물플랑크톤 대증식시에 산염은 활발히 흡수되어 식물플랑크톤 성장에 이용되었고, 질산염은 제한 영양염으로 작용하였다. 중형동물플랑크톤은 수온과 유의한 양의 상관관계를 보였고, 식물플랑크톤과는 음의 상관관계를 보였다. 중형동물플랑크톤은 식물플랑크톤의 대증식이 발생한 $2{\sim}3$달 이후에 개체수가 증가하였다. 증가한 수온과 먹이로 인해 동물플랑크톤 군집이 성장한 것으로 해석된다.

As we considered in the main subjects, investigations on the theory of 'Doctrine on five elements' motion and six kinds of natural factors(運氣學說)' through 'Wang Bing's Commentary(王氷 注本)' of 'The seven great chapters in The Yellow Emperor's Internal Classic Su Wen' ("黃帝內經素問 七篇大論") are as follows. (1) In The seven great chapters("七篇大論")' Wang Bing supplement theory and in the academic aspects as a interpreter, judging from 'forget(亡)' character. expressed in the 'The missing chapters("素問遺篇")', 'Bonbyung-ron("本病論")' and 'Jabeob-ron(刺法論)', 'The seven great chapters("七篇大論")' must be supplementary work by Wang Bing. Besides, he quoted such forty books as medical books, taoist books, confucianist books, miscellaneous books, etc in the commentary and the contents quoted in the 'Su Wen(素問)' and 'Ling Shu("靈樞")' scripture nearly occupy in the book. As a method of interpreting scripiure as scripture, he edited the order of 'Internal Classic("內經")' ascended from the ancient time and when he compensated for commentary, with exhaustive scholarly mind and by observing the natural phenomena practically and writing the pathology and the methods of treatment. We knew that the book is combined with the study of 'Doctrine on five elements motion and six kinds of natural factors(運氣學說)' (2) When we compare, analyze the similar phrase of 'The seven great chapters in The Yellow Emperor's Internal Classic Su Wen'("黃帝內經素問ㆍ七篇大論") through 'Wang Bing's Commentary(王氷 注本)', he tells abouts organized 'five elements(五行)' and 'heaven's regularly movement(天道運行)' rather than 'Emyangengsangdae-ron("陰陽應象大論")' in 'The seven great chapters("七篇大論")'. Also the 'Ohanunhangdae-ron("五運行大論")' because the repeated sentences with 'Emyangengsangdae-ron("陰陽應象大論")' is long they are omitted. And in the 'Youkmijidae-ron("六微旨大論")', 'Cheonjin ideology(天眞四象)' based on the 'Sanggocheonjin- ron("上古天眞論")', 'Sagijosindae-ron("四氣調神大論")' is written and in the 'Gigoupyondae-ron("氣交變大論")', the syndrome and symptom are explained in detail rather than 'Janggibeobsi-ron("藏氣法時論")', 'Okgijinjang-ron ("玉機眞藏論")' and in the 'Osangieongdae-ron("五常政大論")', the concept of 'five element(五行)' of the 'Gemgwejineon-ron("金櫃眞言論")' is expanded to 'the five elements' motion concept(五運槪念)' and in the 'Youkwonjeonggidae-ron("六元正紀大論")', explanations of 'The five elements' motion and six kinds of natural factors(運氣)' function are mentioned mainly and instead systematic pathology is not revealed rather than 'Emyangengsangdae-ron("陰陽應象大論")'. And in the 'Jijinyodae-ron("至眞要大論")', explanations of the change of atmosphere which correspond to treatment principle by 'The three Yin and Yang(三陰三陽)' as a progressed concepts are revealed. Therefore there are much similarity between the phrase of 'Emyangengsangdae-ron("陰陽應象大論")' and 'chapters of addition(補缺之篇)'. Generally, the doctrine which 'The seven great chapters("七篇大論")' are added by Wang Bing(王氷) is supported because there are more profound concepts rather than the other chapter in 'The seven great chapters("七篇大論")'. (3) When we study Wang Bing's(王氷) 'Pattern on five elements motion and six kinds of natural factors(運氣格局)' in 'The seven great chapter("七篇大論")', in the 'Cheonwongi-dae-ron("天元紀大論")', With 'Cheonjin ideology(天眞思想)' and the concepts of 'Owang(旺)'${\cdot}$'Sang(相)'${\cdot}$'Sa(死)'${\cdot}$'Su(囚)'${\cdot}$'Hu(休)' and 'Cheonbu(天符)'${\cdot}$'Sehwoi(歲會)' are measured time-spacially to the concept of 'Three Sum(三合)' the concept of 'Taeulcheonbu(太乙天符)' is explained. In the 'Ounhangdae-ron("五運行大論")', 'The calender Signs five Sum(天干五合)' is compared to the concepts of 'couples(夫婦)', 'weak-strong(柔强)' and in the 'Youkmijidae-ron("六微旨大論")', 'the relationship of obedience and disobedience(順逆關係)' which conform to the 'energy status(氣位)' change and 'monarch-minister(君相)' position is mentioned. In the 'Gikyobyeondae-ron("氣交變大論")', the concept of 'Sang-duk(相得)', 'Pyungsang(平常)' is emphasized but concrete measurement is mentioned. In the 'Osangieongdae-ron("五常政大論")', the detailed explanation with twenty three 'systemic of the five elements' motion(五運體系)' form and 'rountine-contrary treatment(正治. 反治)' with 'chill-fever-warm-cold(寒${\cdot}$熱${\cdot}$溫${\cdot}$凉)' are mentioned according to the 'analyse and differentiate pathological conditions in accordance with the eight principal syndromes(八綱辨證)'. In the 'Youkwonjeonggidae-ron("六元正紀大論")', Wang Bing of doesn't mention the concepts of 'Jungwun(中運)' that is seen in the original classic. In the new corrective edition, as the concepts of 'Jungwun, Dongcheonbu, Dongsehae and Taeulcheonbu(中運, 同天符, 同歲會, 太乙天符)' is appeared, Wang Bing seems to only use the concepts of 'Daewun, Juwun, and Gaekwun(大運, 主運, 客運)'. In the 'Jijinyodaeron("至眞要大論")', Wang Bing added detailed commentary to pathology and treatment doctrine by explaining the numerous appearances of 'Sebo, sufficiency, deficiency(歲步, 有餘, 不足)' and in the relation of 'victory-defeat(勝復)', he argued clearly that it is not mechanical estimation. (4) When we observe the Wang Bing's originality on the study of 'the theory of Doctrine on five elements' motion and six kinds of natural factors(運氣學說)', he emphasized 'The idea of Jeongindogi and Health preserving(全眞導氣${\cdot}$養生思想)' by adding 'Wang Bing's Commentary(王氷 注本)' of 'The seven great chapters("七篇大論")' and explained clearly 'The theory of Doctrine on five elements' motion and six kinds of natural factors(運氣學說)' and simpled and expanded the meaning of 'man, as a microcosm, is connected with the macrocosm(天人相應)' and with 'Atmosphere theory(大氣論)' also explained the meaning of 'rising and falling mechanism(升降氣機)'. In the sentence of 'By examining the pathology, take care of your health(審察病機 無失氣宜)'. he explained the meaning of pathology of 'heart-kidney-water-fire(心腎水火)' and suggested the doctrine and management of prescription. In the estimation and treatment, by suggesting 'asthenia and sthenia(虛實)' two method's estimation, 'contrary treatment(反治)' and treatment principals of 'falling heart fire tonifyng kidney water(降心火益腎水)', 'two class of chill and fever(寒熱二綱)' were demonstrated. There are 'inside and outside in the illness and so inner and outer in the treatment(病有中外 治有表囊)'. This sentence suggests concertedly. 'two class of superfies and interior(表囊二綱)' conforming to the position of disease. Therefore Wang Bing as an excellent theorist and introduced 'Cheoniin ideology(天眞思想)' as a clinician and realized the medical science. With these accomplishes mainly written in 'The theory of Doctrine on five elements' motion and six kinds of natural factors(運氣學說)' of 'The seven great chapters("七篇大論")', he interpreted the ancient medical scriptures and expanded the meaning of scriptures and conclusively contributed to the development of the study 'Korean Oriental Medicine(韓醫學)'.
