동굴은 미지의 세계이고, 암흑의 신비로운 지하세계이기 때문에 우리 인간에게는 매우 흥미로운 공간이라고 할 수 있다. 그러므로 이러한 공간을 관광자원으로 활용하여 지역주민이 소득을 올리고, 청소년에게 탐험의 세계, 모험의 세계는 물론 자연학습의 현장으로 활용할 수 있게 하는 바람직한 경우도 있다. 그러나 이러한 경우 동굴이 개발되면 전자와 같은 긍정적인 면이 있는 반면에 동굴의 파괴, 오손 및 오염과 같은 악영향을 가져오게 되므로 동굴을 개발할 당시부터 악영향을 최소하기 위해서는 환경보전과 환경보호에 커다란 관심을 가져야 한다. 따라서 본 연구에서는 이제 동굴 개장이 2개월밖에 되지 않은 천곡동굴이 관광지로 개방됨으로써 나타나게 될 환경변화를 미리 살펴보고 그에 대한 대책을 마련하려고 하였다. 그 결과는 다음과 같다. 첫째, 천곡동굴의 경우 동굴 공간이 넓고 관광통로가 왕복통로로 되어 있어 체동인구가 2배가 되므로 많은 관광객의 출입시 동굴 내부의 기온이 상승하기 때문에 동시에 관람할 수 있는 적정 관람객 수를 조절해야 한다. 둘째, 천곡동굴은 개장 시일이 오래 경과하지 않았기 때문에 퇴적물의 파손이 전무하다고 할 수 있다. 따라서 이 상태를 계속 유지하기 위해서 동굴 내부에 관리인을 상주시킨다거나, 입동객의 소지품을 보관할 수 있는 장소를 마련하여 동굴퇴적물을 훼손할 수 있는 물건의 반입을 애초에 방지하는 방안도 필요하다고 본다. 마지막으로, 동굴 개발 당시 조명을 너무 가깝게 설치한 때문에 개방 후 얼마 되지 않았음에도 불구하고 몇 군데에서 녹색균류가 관측되고 있으므로 조명시설의 원거리 조정이나 간접조명 대책을 강구해야 한다.만 아니라 오류의 크기도 확률적으로 변하는 상황을 모형에 반영하여 보다 현실성있게 모형화하였다.균 6.5점(2-9점)으로 대체로 높게 나타났는데 이는 대중매체와 신문, 잡지류를 통한 지식의 정보가 많기 때문으로 생각된다 비만 정도에 따라서는 유의적인 차이를 보이지 않았다. 5. 비만 정도와 상호간의 관계를 보면 BMI 수치가 높을수록 비만인 형제수가 많았으며, 자신의 비만 자각도도 높았다. 편식율은 비만 정도가 낮을수록 높았으며, 식품섭취 빈도 점수는 비만군에서 높았으나, 저녁식사 후 간식섭취는 BMI가 높은 군에서 하지 않는 비율이 더 높았는데 이것은 감수성이 예민한 여학생들이 자신의 외모에 대한 의식적인 노력으로 보인다. 이상과 같은 결과를 종합해 볼 때 중학교 여학생들은 학교수업을 중심으로 비교적 규칙적인 생활을 하고 따로 운동을 할 시간이 많지 않은 것으로 나타났다. 비만과 관련하여서는 유전적인 요인도 중요하지만 식습관 개선과 식품이 적절한 선택 등을 강조하여 연령과 생활환경에 맞는 영양교육이 필요하다고 본다.알 수 있으며, 현미 30% 첨가한 B2가 그 다음 순위로 선호되어, 백설기 제조에서 율무와 현미의 첨가량은 10%가 권장된다.농촌 지역 여고생보다 많이 섭취하였고, 탄수화물은 농촌지역 여고생이 대도시 지역 여고생에 비하여 유의적으로 많이 섭취하였다. 지역별 여고생의 에너지섭취 비율은 탄수화물 : 단백질 : 지방의 섭취 비율이 대도시 60.75% : 16.4% 22.9%이며, 중소도시가 62.7% : 15.7% : 21.5%,농촌이66.8% : 14. l% : 19.1%이었다. 영양지식의 정확도나 인지도는 영양소 섭취와 유의적인

The importance of color is increasing in modern life and we call such present age that is color age. These day that all areas of life are being getting fashionize, ordinary people as well as design specialist are required of culture and knowledge about color. Color is important factor of marketing because ability that color appeals to human's sensitivity is bigger than form. Color design education is important curriculum at liberal arts course and in special design training course. Color expresses by hue, value and chroma but design spot is using mainly hue and tone color system. Therefore, it is very important that educate tone concept in color design education But research of hue and tone color system is insufficient in domestic. We educate foreign color system and use mainly imported color paper. When think influence that increase of color, we must develop hue and tone color system in suitable for color design education and plan the color paper that conform to it. This research designed usable "Hue and Tone Color System 253" for general color design education. Also I designed 121 color papers for primary grade, 181 color papers for intermediate grade, 253 color papers for higher grade of color design education as specific practical use of "Hue and Tone Color System 253".or System 253".

The problem of supply and transport of sediment from a mountainous catchment is very important in explaining dynamic geomorphology and the hydrological cycle. The discharge of suspended sediment is determined by a morphological system. Human interference to environment Is also an important, not negligible factor in sediment production. Moreover, growing concern in recent years for the problems of nonpoint pollution and for the transport of contaminants through terrestrial and aquatic ecosystems has highlighted the role of sediment-associated transport in fluvial systems. This study was conducted in forested and quarried catchments in order to clarify the different discharge process and the mechanism of suspended sediment dynamics for each catchment. As a forested catchment, the Yamaguchi River catchment which drains a $3.12km^2$ area was chosen. On the other hand, the Futagami River basin which is formed by three subbasins (1.07, 1.59 and $1.78km^2$), as a quarried catchment was selected. These catchments are situated to the north and east of Mt. Tsukuba, Ibaraki, Japan. The discharge pattern of suspended sediment from the Futagami River basin is more unstable and irregular than that from forested catchment, the Yamaguchi River catchment. Under the similar rainstorm conditions, suspended sediment concentration from quarried catchment during a rainstorm event increases from 43 to 27,340 mg/l. However, in the case of the forested catchment it changes only from nearly zero to 274 mg/l. Generally, the supply source of suspended sediment is classified into two areas, the in-channel and non-channel source areas. As a result of field measurements, in the case of the forested catchment the in-channel (channel bed, channel bank and channel margin) is the main source area of suspended sediment. On the other hand, remarkable sediment source area on the Quarried catchment is the non-channel that is unvegetated ground.

Invasive alien species are considered to be one of the main factors that cause biodiversity loss. Establishment of management strategies through continuous monitoring and risk assessment is a key element for invasive alien species management policy. In the present study, we introduce examples of ecological risk assessment tools developed in Japan, Germany-Austria and Belgium. Invasive alien species have been designated in Japan based on the assessment of risks to ecosystems, human health and primary industry. German-Austrian Black List Information System categorized alien species into Black List, White List and Grey List according to their risks to biodiversity. In the Harmonia Information System developed in Belgium, invasiveness, adverse impacts on native species and ecosystem functions and invasion stages were assessed and alien species were categorized into Black List, Watch List and Alert List. These international risk assessment tools may be helpful to improve our national risk assessment protocol for the prioritization of invasive alien species management.

Religion is the symbolic form and action, linking the ultimate condition of life with human beings. Religious idea grasps the world through symbols and gives birth to the action through symbols. This research put its purpose in elucidating the effect of religion on the costume and its mechanism. It's focus is centered on Buddhism, Hinduism, and Islam which are among the world high religions. Part of this research also examines the mechanism in which several composing factors are expressed with rituals and manifested with costumes, this process was diagrammatized and suggested. The composing factors of religion such as belief system, experiences, community, and rituals are closely related. Ritual especially, is the symbolic action, practice, and the way of rescue, expressing religious meaning. Religious rituals such as imitative rituals, positive or negative rituals, sacrificial ritual, and rites of passage have been expressed with religious music or figurative art such as costume, construction, and art as well as religious ritual like ancestral rites. Religion has had a great effect on the overall culture including costume as a belief system by lightening the meaning of life and suggesting the solutions to the human problems such as anxiety or conflict.

North Korea discourse is doubtful. A considerable portion is distorted under political objectives, group identity, and interests. Surely, there are facts based on North Korea's conducts. Apparent deceptions commonly exist as well though. Korean media does not endeavor to set the records straight and there are no revision towards mislead information. This is substantially dangerous as it can misjudge North Korean policies, beget national antipathy, and interferes with rational and constructive policy making. This study stems from such concerns and takes such cases as HEU(Highly Enriched Uranium) suspicion of 2002, dispute covering BDA(Banco Delta Asia)'s counterfeiting, and the abandonment of the Geneva Agreed Framework into consideration. The first part concentrates on fathoming the truth of the three cases. References from US government, academia, think tanks, media were inquired with an addition of secondary material from Korea and China. Secondly it examines whether domestic news properly reflects the precedent facts along the process of discovery. The cause and solution suggested by domestic media were organized and inductively reconstituted to frames. The last study questions the structural factors that reproduces suspicion analogs. Today's dangers facing Korean society are essentially not natural but artificial. This research hopes to foster peace by analyzing related discourses that are infamous to reinterpret reality.

This study suggests a proper studying direction of research on relationship addiction problem. And it presents fundamental research data by analysing domestic research trends of relationship addiction among various crises of people have addiction problem. For analysis of trends on relationship addiction, I searched almost all master's and doctoral dissertations and academic journals which were studied on "addiction", "relationship addiction", "addiction relationship" from 2005 to 2019 in Korea. Also I have surveyed various publications in the data base of Research Information Sharing Service, academic research data base, the National Assembly Library and the National Central Library in Korea. And for the reasonable results, I have studied the research according to 4 steps such as "collecting data and analyzing precedent research", "building analysis criterion", "cording and analysis", "making conclusion and suggesting the development direction" The results of this study are like these. The total number of researches on relationship addiction is 67. The object of those studies were limited adult's or undergraduate students's relationship addiction. So it is necessary that the fields of relationship addiction research are expanding gradually. And the research shows that the relationship addiction problem is directly related with sexual prostitution. Therefore, there are enough needs to study more in diverse, different point of view. Also it is suggested that the proper analyses methodology of relationship addiction shoud be used and new analysis criterions should be developed. In this study, the necessity of further more study is proposed in various ways of methodology about the relation of social problem and relationship addiction. And from this study, it is proved that expending the objects and fields of the study on relationship addiction, the factors analysis on addiction, study models of addiction must be necessary to be studied.

최근 여러 가지 요인으로 가뭄이 빈발하고 있으며, 가뭄을 대비한 과학적 저수지 운영이 절실하다. 유입량, 관개용수량, 저수량, 하천유지유량 등 저수지 물수지를 반영하여 실제 가뭄 상황에 적용할 수 있는 시스템으로 개발하였다. 여기서, 하류 하천의 수량을 양수하여 저수량을 확보하는 양수저류를 고려하였고, 시기별 관개용수량을 간단관개, 절수관개 등의 실제 상황을 반영하도록 하였다. 또한 저수량의 장기간 변화를 관찰하여 저수지 운영의 가이드라인을 설정할 수 있도록 하였고, 하류 하천의 유량 변화도 평가할 수 있도록 하였다. 최근 수차례 가뭄을 겪은 충남 홍성에 위치한 대사저수지에 개발된 시스템을 적용하였다. 대사 저수지는 유역면적 $2.9km^2$, 유효저수량 137만$m^3$, 수혜면적 163ha에 이르며, 유역면적 $72.2km^2$인 하류하천의 와룡천으로부터 $0.057m^3/s$씩 양수하여 저수량을 확보하고 있다. 일별 저수율 자료가 있는 1991년부터 2016년까지 분석한 결과는 다음과 같다. 양수는 1월 15일부터 5월 31일까지 실시하는 것으로 하고 결과를 정리하였다. 첫째, 일 저수위를 모의하여 검증한 결과 일평균하여 관측 저수위는 EL.84.58m, 모의 저수위는 EL.85.87m이었다. 이 때 강우량은 연평균 1,275.2mm, 유입량은 718.0mm, 유출률 56.3%, 수면증발량 11.5만$m^3$, 관개용수 공급량 117.5만$m^3$, 월류량 148.9만$m^3$이었다. 둘째, 양수로 인한 유입량의 변화는 양수 전에는 연평균 209만$m^3$(유출률 56.3%)에서 양수 후 276만$m^3$(74.7%)로 증가하였고, 양수량은 67.5만$m^3$(연유입량의 32.3%)이었다. 셋째, 하류 와룡천의 유량은 양수 전에는 연평균 연유출량 5,200만$m^3$(유출률 56.5%)에서 양수 후 5,120만$m^3$(55.6%)으로 나타났다. 넷째, 양수 전에는 일평균 저수량이 47만$m^3$에서 양수 후 76만㎥으로 증가하였고, 양수저류로 인해 이수안전도는 15.4%에서 92.3%로 개선되었다. 또한 양수로 인해 저수지 유입량은 연평균 32.3% 증가하였고, 하류하천의 유량은 1.55% 감소하였다. 이상의 분석 결과로 양수저류는 가뭄대응에 상당한 효과가 있다고 평가할 수 있다. 또한 다양한 여건을 고려한 저수지 운영 가이드라인의 합리적 설정으로 보다 적극적인 가뭄대응이 필요하다고 본다. 물관리 현황은 지구별, 저수지별로 다양하다. 향후 현장 상황에 적합한 물관리 방법을 적극 모색해야 하며, 자연과 인간의 평등한 물 이용 환경조성에, 여기 개발한 도구가 일정 부분 유용할 것이라 판단한다.
