하천 유사량은 유량과 마찬가지로 충적 하천의 기본적인 자료로서 하상변동 예측, 저수지 퇴사량 추정, 유사 유출량 추정, 하도 계획과 설계, 유사조절 계획 수립 등에 다목적으로 활용된다. 선진 외국의 경우는 유사량관측망을 구축하여 일찍이 유역관리 및 하천관리, 하천시설물관리 및 댐 관리 등을 위한 자료를 생산하고 있으나, 국내의 경우는 유사량 측정 기반 및 실측된 유사량 자료가 부족한 관계로 단순한 가정이나 경험식에 의한 추정치들의 활용 빈도가 높다. 본 연구에서는 국내 특성에 맞는 관측망을 구축하기 위해서 국내외 관측망 구축 사례 등을 조사 분석하였으며, 이를 토대로 유사량관측망 구축 방법을 개념화하였다. 개념화된 유사량 관측망 구축방법은 유역관리, 하천관리, 하천시설물 관리, 댐 관리 측면을 포괄하는 방법으로 관련계획 및 설계기준 검토, 유사량조사 현황 검토, 설계대상 수위관측소 선정, 현장조사 등의 과정을 필요로 한다. 본 연구에서는 관측망 구축대상 지점을 국가수위관측망(643개소)로 하였으며, 이를 통해 총 138개소의 유사량관측망을 목적별로 구축하였다. 권역별로는 한강권역 44개소, 낙동강 권역 37개소, 금강 권역 33개소, 섬진강 권역 12개소, 영산강 권역 12개소로 구축되었다.

본 연구는 금강 지류인 갑천 유역을 대상으로 3개 지점에 대한 2006년의 가용한 수문관측 자료 및 유량측정 성과를 이용하여 상 류 지점 간 유출특성을 분석하였다. 2006년도 금강 유역의 유량측정 지점 중 도심하천에 속하는 갑천 유역의 3개 지점을 선정하여 유량측정성과에 대한 수리특성 분석, 불확실도 분석 및 수위-유량 관계곡선식을 개발하여 유량을 산정하였다. 산정된 유량에 대한 상 하류 간 유출 검토, 연유출률 검토, 상 하류 간 동시유량 검토 등을 통하여 각 지점의 최종 유량을 확정하였다. 산정된 유출률은 가수원(69.1%), 유성(72.3%), 회덕(66.8%)로 산정 되었으며, 부분적으로 계기수위가 불안정한 오차들을 제외하면 지점들의 유출률은 그 지점들의 특성을 감안할 경우 비교적 안정적인 범위내의 유출특성을 보였다. 2005년도 유출률과 비교해 보면 전체적으로 다소 높게 나타났으나, 올해 단기간 집중된 강우 특성을 고려한다면 적절한 유출범위를 보인 것으로 판단된다. 그리고 향후 전문인력에 의한 수문관측과 일상적인 검증과정을 통해서 정밀한 유량측정성과를 확보한다면, 보다 신뢰성 있는 유출특성을 분석할 수 있을 것이며, 효과적인 치수 및 이수계획의 수립 등 수자원 개발을 위한 기반을 마련할 수 있을 것이다.

The Development of a new menu item in a restaurant usually begins when your chef prepares a creative "brainchild" that he serves to you, the owner. If you are satisfied with the new dish, It gets a "go-ahead" signal, under the assumption that what appeals to you will appeal to a significant number of your customers. While many excellent and successful items have been created this way, It is not reasonable to expect that your tastes can represent the wide variety of your potential guests tastes. The purpose of this study is to examine the factors that have an influence on customers′ menu evaluation. A menu is a marketing tool which delivers restaurant′s image and message to customers needs and wants to restaurant. So far, studies on menu have been done in an analytical way from a management′s viewpoint and inadequate to reflect customers′ needs and wants. In this study is to examine the factors that have an influence on customers′ menu evaluation. The factors affected the customers′ menu evaluation of hotel restaurant in the three factors. Three factors are food service factor, menu copy factor, value of food. Correlation between the evaluation of criteria and selection of menu was examined. All Three evaluation criteria have shown strong correlation with selection of menu of these criteria, menu-copy factor was found to be most strongly correlated with selection of menu. In conclusion, As a study on the Customer′s evaluation factors of the Korean restaurant menus in hotels, It raises to exert us strength in the menu management of Korean restaurant.

As review text contains the experience and opinions of the customers, analyzing review text helps to understand the subject. Existing studies either only used sentiment analysis on online restaurant reviews to identify the customers' assessment on different features of the restaurant or network analysis to figure out the customers' preference. In this study, we conducted both sentiment analysis and network analysis on the review text of the restaurants with high star ratings and those with low star ratings. We compared the review text of the two groups to distinguish the difference of the two and identify what makes great restaurants great.

본 논문에서는 실제 규모 데이터센터의 3D 모델링을 기반으로 대상 공간별 화재 시나리오를 선정하여 화재 및 피난 시뮬레이션을 수행하였다. FDS와 Pathfinder는 full coupling 방식을 사용할 수 없는 한계가 있으며 semi coupling의 경우 가시화에는 도움이 되나 결과에 영향을 주지 않는다. 따라서 재실자의 피난 상황 시 경로에 대한 안전성과 화재 위험 노출 정도를 시각적으로 분석하는 것이 가능한 semi coupling과 시뮬레이션 결과 데이터 분석을 병행하여 수행하였다. 전산실의 경우 서버의 기능상실 한계 온도가 32도이기 때문에 서버 기능 정지 상황에 도달하는 시간을 중점적으로 분석하였다. 전산실은 업무 및 고객 서비스와 관련된 모든 데이터들을 저장하기 위해 항시 기동 되어야 하는데 전산실 내 화재가 발생할 경우 1~2분 이내 서버 기능이 정지되는 상황이 발생하였다. 따라서, 서버가 안전하게 계속 동작하기 위해서는 전력 계측 및 제어 케이블 열화, 서버 장치의 건전성이 유지되어야 하며 초기 화재를 빠르게 감지하여 진압하여야 한다. 피난 시뮬레이션의 경우 가시도를 상실하게 되는 시간이 약 195초(5m 미만) 인근으로 인원이 해당 층을 완전히 벗어나는 데 걸리는 시간이 약 125.6초였던 것을 보면 대피하기에 충분한 허용 피난시간(ASET)을 확보하고 있음을 알 수 있었다.

As the proportion of women's participation in economic activities is rising, the increase of husband and wife both working and nuclear families makes children up-bringing a social problem. But many families have difficulties by the shortage of day nurseries which can solve it. As we can see in the research, the most urgent problem is the extension of nurseries in quantity. In Taegu, since it became a wide-area city, there are 473 nurseries. But in the respect of distribution, only less than 10% of Dongs have more than 7 nurseries and more than 90% of Dongs have less than 7 nurseries. Consequently nurseries are extremely insufficient. Moreover 29 Dongs don't have any nurseries at all and they take 18.6% of Dongs. The second problem is the unbalanced distribution of nurseries. West and north ward which are industrial complex and swarmed with low-income families, and Tal-sung county which is recently included in the wide-area city keenly need the establishment of nurseries. Besides, Bi-san 1 Dong and Non-gong which have only $1{\sim}2$ nurseries though they have high proportion of children and women who can be pregnant are also the areas which take precedence of nursery establishment. The third problem is that government support must be increased in the areas which have many small, petty and profit-making private nurseries so that good quality teachers can make breeding activities in nice facilities and environment. In materials which are obtained by the interviews with publich servants in charge of family welfare in some ward offices. Young and unexperienced persons who aquired certificate of qualification take day-nursery permits and run nurseries only a few months. and if the profits are insufficient, they sell the nurseries for premiums to third persons who are not qualified. Then the third managers only think of profits without thought of good quality childcare. As the result, the nurseries become asylums not nurseries. That is why the conditions of nursery establishment must be restricted to suitable scale and experienced persons. The fourth problem is that the nurseries in work places are extremely insufficient. The women who have jobs have many things to do before they go to work such as preparing meals and leaving children in the care of someone. Hence the childcare problem of working women must be solved. In nuclear families, childcare is the most serious problem for working women. The fifth one is the reduction of childcare expenses. Women must sacrifice themselves a lot to make social activities. To say nothing of physical and mental burden, they have to spend much of their salaries on childcare. And yet they don't take the benefit of good quality childcare. For the participation of women in public affairs, society must support the childcare problem to have then be devoted to their jobs without worries about their children. Therefore Taegu wide-area city must select west, north ward which are industrial complex and the low-income swarmed area before everything and establish many national, public and corporate nurseries which cost less expenses.

The purpose of this study was to demonstrate exploring the field application of combined cognitive-motor learning program based on proprioceptive neuromuscular facilitation and Bartenieff Fundamental program. The combined cognitive-motor learning program(CC) was applied to the 10 MCI elder while 10 elder in occupational therapy(OT) took cognitive learning class. MMSE-K, Time up & go test(TUG), Tandem gait test(TA), GQOL-D were measured and analyzed. The collected data were analyzed by Independent & Paired T-test. The results were as follows: Both groups showed similar learning effect in MMSE-K test. However, in TA & GQOL-D test, CC group showed significant learning effect than OT group. From these result, we conclude that combined cognitive-motor learning program is valuable as alternative program for cognitive development and social development as well as physical development of MCI elder.

The purpose of this study is to analyze the effectiveness of secondary school SMART education. In order to achieve this, the paper separated the high school which implements the smart education for the high school and the high school which did not apply the smart education concept, then figuring out the answer about what school is more effective, the influence of the smart education concept on the students' emotions and academic achievement. This paper analyzed the effectiveness of SMART Education between Hansol high school in SeJong city and Jungang high school in Gwachen city by using 'schoolinfo (www.schoolinfor.go.kr) SMART education.' This study first presented the SMART Education's concept and characteristics through reviewing some literature, and then categorized the characteristics by using the items included academic achievement and emotional effect. These items consist of the 'students academic scores' for the academic achievement, 'the number of students dropped out' and 'the damage rate of school violence' for the emotional items. The conclusion of this study is that Hansol high school indicates lower school violence rate than Gwachen high schools with the two school's violence rate decreasing. Moreover, students' score of Hansol high school is higher than high schools in Gwachen city. The SMART education school budget structure is 'Common type', which requires a lot of investment to 'Basic education activities', 'educational activities support', 'School general operating expenses' among education budget items.
