This study has an object of searching for appropriateness in applying the trip distribution model by studying the changes of the character of parameter which the model contains and by analyzing and evaluating trip distribution technique out of few steps of pre-estimate technique for the traffic demand through computer simulation centering around Kwangju. Method of this study is investigating the basic theory for trip distribution model and with this grounding, I rearranged it as research data for trip distribution model compatible for Kwangju, using data such as research data on actual state, the statistics annual report and basic plan for traffic full equipment of Kwangju. So, The most stable measure of the type of trip distribution of Kwangju city was produced in Fratar and Detroit model, however, gravity model has a little bit low reliance in sharing of estimation and actual survey although it is astringent in short period.

국내에서의 수제는 하안 및 제방의 보호, 유로제어 및 주운 등의 목적에 의해 설치되기 보다는 수제로 인해 발생되는 수제역(recirculation zone)의 다양한 흐름이 수중생물의 다양한 서식처 및 홍수 시 어류의 피난처 제공한다는 환경적인 목적이 지배적이다. 따라서 홍수시 하천의 통수능 감소영향이 상대적으로 작고 국부세굴에 대해 안정적인 경사형 수제에 대한 관심이 크며 몇몇 곳에서는 시공되어 졌다. 하지만 경사수제에 대한 설계기법은 현재 미미한 상태이며 선행되어져야할 구조물 주변의 흐름해석에 관한 연구도 미미하다. 이에 본 연구에서는 3차원 수치모형을 적용하여 주수로와 수제역의 흐름해석을 수행하였다. 연구내용은 수리모형변화와 수치모형실험을 병행하여 수행하여 수치모형결과를 검증하였으며 그 결과를 적용하여 경사형 수제주변의 흐름을 해석하였다. 수치모형은 Flow 3D모형을 이용하여 경사형 수제조건에 따른 흐름해석을 수행하였고 수리모형실험은 수치모형과 동일한 2가지 조건에 대해 수행하여 수치모형결과와 비교 분석 하였다. 본 연구의 목적은 경사형 수제설치로 변화되는 수제역 흐름을 3D 수치해석으로 분석하여 수제역의 환경적 효과(수중생물의 서식처 등)에 대한 기초자료를 제공하는 것이다. 연구결과, 수치모형실험은 수리모형결과와 일치하였으며 경사형 수제특성에 따라 수심별 흐름변화를 분석할 수 있었으며 기존 불투과 및 투과수제와 다른 결과를 도출하였다.

To date the major business investments have been made in CRM continuously, even though many executives realized the return expected from the investment in expensive cutting-edge IT components for CRM system. However, researcher have not clearly answer the role and effects of CRM systems. The research is designed to identify the CRM system's chain-reaction effects, to investigate the relationships between factors identified, and to provide the roles and effects of CRM system in strategic perspectives. The findings illustrate that the improved information capability and enhanced competitive advantages encouraged by the CRM system implementation may lead strategic performances improvement, and finally financial performance improvements.

'-느라고'의 후행절 부정 의미 제약에 대하여 연구자들마다 의견을 달리하고 있지만 대부분의 교육 교재는 다수의 연구 내용을 반영하여 '-느라고'의 후행절에 부정 의미 제약이 있다고 제시하고 있다. 하지만 교육 교재에서 후행절에 부정 의미의 제약이 없다는 연구 내용이 배제되어야 한다면 이를 위한 심층적인 논의가 필요하며 타당한 근거가 있음을 밝혀야 한다. 본 연구는 '-느라고'의 후행절 부정 의미 제약에 대해 상반된 주장이 나오게 된 것에 주목하여 실제로 '-느라고'가 후행절 부정 의미 제약을 갖는지, 만약 제약을 갖지 않는다면 그 이유는 무엇인지 밝히고자 하였다. 이를 위해 세종 문어 원시 말뭉치에서 '-느라고'의 문장 1,601개를 추출하고 혹시 있을지 모를 통시적 변화를 제거하기 위해 교육 교재들이 집필된 2000년대의 문장만 선별하여 후행절의 의미를 확인하였다. 그 결과 323개의 문장 중 98개 문장, 33.3%가 후행절에 부정적인 의미를 갖지 않고 있는 것을 확인되었다. 이는 '-느라고'가 단순히 후행절 부정 의미 제약을 갖는다고 할 수 있는 수치가 아니었다. 부정 제약의 범위를 파악하기 위해 문장의 의미를 살펴 목적의 의미를 갖는 '-느라고'와 이유의 의미를 갖는 '-느라고'로 분류하였다. 이렇게 분류한 '-느라고'의 후행절을 다시 분석한 결과 이유의 '-느라고'에서는 후행절 부정 제약이 실현되고 있었지만 목적의 '-느라고'에서는 부정 제약이 발견되지 않았다. 따라서 '-느라고'가 이유와 목적의 의미를 가지며 이유의 '-느라고'로 실현될 때에만 부정 의미 제약을 갖는다는 보다 심층적이고 구체적인 연구 결과 얻어 냈다.

In the case of the hotel restaurant, the purpose of using the hotel affects largely to the type or the menu and nowadays it becomes essential to find out the characteristics of the hotels and make the strategy within them. Therefore, the purpose of this study is analyzing that even if the customers have the similar characteristics and preferences, they choose different menu because of the purpose of the visit, and the image of the hotel. And also this study gives basic data for the strategic menu management, the target of this research was the super deluxe Italian restaurant. Using the sales data of this restaurant, we analyzed the menu what people like most, and moreover, we analyzed the menu-choice behavior about each hotel. This study has a important role as a basic data that gives more profit to the restaurant, but also satisfaction to the customers.

The purpose of this paper is to examine the change of Korean land transportation system and pattern during 1905-1911 concentrated on road construction so-caued ‘Sinjak-ro’. As conclusions, modem road or ‘Sinjak-ro’ started from modem port to inner hinterland where economic resource or regional center located. A trunk railroad running through Korea Peninsula from Busan to Sinuiju(border between China) is opened its complete operation in 1906 by Japanese investment, when no ‘Sinjak-ro’ road construction begun. Thus from the beginning, railroad station also became important starting point of ‘Sinjak-ro’ as seaports. Before the Japanese annexation of Korea, the ‘Sinjak-ro’ road was constructed mainly between seaport or station, where Japanese commercial settlement located, and hinterlands to help their economic invasion. This study could not deal with other modem transportation systems such as railroads and waterways. It is necessary to examine whole changes of modern transportation systems in this age so that we would comprehend modernization feature of Korea from the viewpoint of transportation history.

This study is to investigate the effecting factors on using ICT ability, and using computers for learning through PISA 2009 Korean data. Multi-level analysis is adapted to hierarchical nested data. Results show as follows: First, using ICT ability is affected by variables on the student level, but not on the school level, except in ESCS. Second, using computers for the purpose of learning at home is also affected by variables on the student level, but not on the school level, except in ESCS and in the size of region. Third, using computers for learning at the school is more influenced by variables on the school level like ESCS, the size of region, the ratio of computers, and the student-teacher ratio. The results suggest planning a computer education policy with considering both personal and school differences based on the multi-level approach.

With the spread of social networks, platform-based social commerce has grown rapidly with the use of multiple smart devices. Given the rapid growth of social commerce sites such as Coupang and Ticket Monster, it is very important to understand the user's purchase decision-making process in a social commerce environment. The purpose of this study is to develop a richer understanding of the goals of users using social commerce. Second, a methodological alternative for analyzing the user's goals is introduced. In this study, laddering interview and means-end chain analysis were used. As a result of interview conducted on 40 users who have more than 6 months of purchasing experience using social commerce, a hierarchical goal map showing the user's goal structure was derived. This map contains 22 ultimate goals of social commerce, including warm relationships with others, fun and enjoyment of shopping, accomplishment, satisfaction, financial saving, and convenience. In addition, there are various paths from activities to ultimate goals, so investigating the goals pursued by users can give us insight into understanding user.

Two global optimization methods, the SCE-UA method and the Annealing-Simplex(A-S) method for calibrating a daily rainfall-runoff model, a Tank model, was compared with that of the Downhill Simplex method. In synthetic data study, 100% success rates for all objective functions were obtained from the A-S method, and the SCE-UA method was also consistently able to obtain good estimates. The Downhill Simplex method was converged to the true values only when the initial guess was close to the true values. In the historical data study, the A-S method and the SCE-UA method showed consistently good results regardless of objective function. An objective function was developed, which puts more weight on the low flows.

복식은 실용적인 목적과 함께 신체를 아름답게 장식하여 인간의 미적 감각을 충족시키는데 그 목적이 있다. 이러한 복식의 미적요소를 표현하는데 있어 장식기법은 중요한 하나의 수단이 된다. 장식기법 중 개더는 완성된 하나의 조형물로 사용되는 것이 아니라 복식을 통해서만 실현될 수 있는 것이기 때문에 전체 복식 안에서 개더가 어떻게 표현되고 있는가에 대해 살펴볼 필요가 있다.(중략)
