전화를 거듭하고 있는 IT산업의 그 중심에서 스마트폰이 활약하고 있다. 국내 시장에서도 스마트폰은 급속하게 확산되고 있지만 현재까지도 소비자들이 왜 스마트폰을 사용하는지에 대한 실증적 분석을 통한 선행 연구는 드물다. 본 연구에서는 정보시스템의 사용자 만족과 습관이론을 바탕으로 스마트 폰 사용에 대한 원인과 결과에 관해서 실증적으로 검증하였다. 본 연구는 스마트폰 사용자 278명을 대상으로 분석하였고 인지된 유용성과 사용 용이성이 스마트폰 만족에 긍정적인 영향을 주는 것으로 나타났다. 흥미로운 발견은 사용자 만족이 스마트폰 사용 습관과 탐색적 사용에 (+)정의 영향을 주지만 충분한 활용에는 영향을 주지 않는 것으로 나타났다는 것이다. 이는 습관이라는 매개 효과가 충분한 활용에 영향을 주고 있으며 자기효능감의 통제변수가 영향을 주기 때문이라고 할 수 있다. 마지막으로 스마트폰을 사용하면 할수록 사용자는 탐색적으로 새로운 스마트폰 기능에 관심을 기울이는 것으로 조사되었다.

본 연구를 통해 정의된 용도복합 개념은 세 가지 이상의 주요 도시기능의 복합을 의미하며 도시공간의 경제적, 사회적, 환경적 가치를 동시에 실현하기 위한 수단을 의미한다. 이러한 정의 하에서 서울의 용도복합 현상을 탐구하였다. 상대적 엔트로피 개념을 사용하여 단위 지역인 법정동을 기준으로 복합도(R.E.)를 측정하였으며 도시기능의 유형은 용도복합의 정의에서 도출한 개념을 통해 건축물 층별 용도를 유형화하여 계량화하였다. 서울의 용도복합 현상은 복합도(R.E.) 0.631 이하를 '복합아님', 복합도(R.E.) 0.631 초과 0.884 미만을 '불균형 복합', 복합도(R.E.) 0.884 이상 0.991 미만을 '균형복합', 복합도(R.E.) 0.991 이상을 '완전균형복합'의 단계로 구분하여 용도복합 현상을 해석하는 기준으로 지표화하였다.

본 연구의 목적은 의사들이 환자 치료와 학술적인 연구를 하기 위해 요구하는 정보를 효율적으로 제공하는데 그 목적이 있다. 2007년 12월 3일부터 12월 21일까지 3주 동안 의사 177명을 대상으로 조사하였으며 이용자들의 정보요구와 이용행위로 정보수집방법과 정보원, 그리고 도서관 이용정도와 만족도를 평가하였다. 의사들은 최근의 연구동향을 알고자 할 때와 환자 치료를 위해 정보를 가장 많이 필요로 하는 것으로 나타났다. 의사들이 그들의 정보요구를 충족시키기 위해 선호하는 정보수집방법은 인터넷 검색으로 그 이유는 정보접근의 편이성과 정확성, 최신성인 것으로 나타났다. 의사들은 정보가 필요할 때 주로 도서관을 이용하여 필요한 정보를 얻는 경향이 있으나 대체적으로 보아 도서관 이용빈도수는 매우 적은 것으로 나타났다.

In the urban area where rapid suburbanization trend continues, the role of mixed use building is controversial. It is argued that the mixed use building is an effective tool to recover residential function of urban core(urban regeneration). It is also argued that the building is a cause of serious urban problems, such as congestion, public service shortages. The fundamental purpose of this study is to examine the role of mixed use building in terms of urban growth management in Seoul. For this purpose, data of mixed use building from 1981 to 2007 are collected and analysed. The results show that most of mixed use buildings are located in either sub-centers or population losing areas, rather than traditional urban core. Therefore, it is hard to accept that the two controversial arguments. The mixed use building noncore areas in most cases. However, it dose help to increase population inflow in non-core areas. it is difficult to accept the public service assertion which states that super-high rise mixed use building causes public service congestion, because the building is built in population losing or demand decreasing area. Based on these findings this study suggests some policy alternatives such as urban service boundary or concurrency program to management urban growth.

Purpose: This study attempted to develop clinical guidelines to help patients use hospice and palliative care (HPC) at an appropriate time after writing physician orders for life-sustaining treatment (POLST) by identifying the characteristics of HPC use of patients with terminal cancer. Methods: This retrospective study was conducted to understand the characteristics of HPC use of patients with terminal cancer through decision tree analysis. The participants were 394 terminal cancer patients who were hospitalized at a cancer-specialized hospital in Seoul, South Korea and wrote POLST from January 1, 2019 to March 31, 2021. Results: The predictive model for the characteristics of HPC use showed three main nodes (living together, pain control, and period to death after writing POLST). The decision tree analysis of HPC use by terminal cancer patients showed that the most likely group to use HPC use was terminal cancer patients who had a cohabitant, received pain control, and died 2 months or more after writing a POLST. The probability of HPC usage rate in this group was 87.5%. The next most likely group to use HPC had a cohabitant and received pain control; 64.8% of this group used HPC. Finally, 55.1% of participants who had a cohabitant used HPC, which was a significantly higher proportion than that of participants who did not have a cohabitant (1.7%). Conclusion: This study provides meaningful clinical evidence to help make decisions on HPC use more easily at an appropriate time.

Manufacturing flexibility has strategic position in improving competitive advantage as a mechanism that responses environmental uncertainty. Thus this study aims at recognizing strategic meaning of manufacturing flexibility in enhancing the competitive advantage and measuring manufacturing flexibility and ultimately analyzing the effects of IT use on the manufacturing flexibility. Consequently we proved that IT use have an effect on manufacturing flexibility and manufacturing flexibility has an effect on competitive advantage in this study The results of this study are as follows. First, information acquisition and decision support by IT use has a significant effect on enhancing the manufacturing flexibility and manufacturing flexibility has a significant effect on improving the competitive advantage. Theses results are also means that IT use to support AMT usage is more important than AMT itself in the achieving manufacturing flexibility.

This study focuses on the planning and actual use of the transitional spaces in the residential-commercial mixed-use buildings. The range of case study include from the year of 1960's to 2000. Through the case study and field survey, we can extract the elements of the transitional space and the problems of Mixed-Use building from the viewpoint of transitional space. According to the field survey, most of the residential-commercial mixed-use buildings contain the transitional space to some degree, but there need to be a more active planning method to secure the residential factors and for this reason, the application of the transitional space must be emphasized at a higher level.

The purpose of this study is to offer essential information related to early childhood education and care policy. Using the Korea Labor and Income Panel Study(KLIPS) Vol.5., this study analyzed sociodemographic factors that decide the use and type of institute for early childhood education and care. The following results are obtained： First, it is not easy for young children under three years old to use education and care institutes because of their preference for home care. Second, the mother's job status affects the child's use of child care centers and private institutes for education except for the using of early child education centers. Third, the affecting main factors for the use of child care centers are quite similar to critical factors for use of the private institute for education. Thus, young children using the private institute for education could be interpreted as coming from a low-income class compared with the children using the early child education centers.

Under the context of the recent curriculum reform in Mongolia emphasizing technology integration in schools, the main purpose of this study was to examine external and internal factors that influence teachers' use of technology. This study aimed to investigate structural relationships between school support, technology use, and TPACK (Technological Pedagogical and Content Knowledge) among Mongolian secondary school teachers. This study was conducted with 208 secondary school teachers in Ulaanbaatar, Mongolia. Data were collected through an instrument that measures three factors: teachers' use of technology, TPACK, and school support. The results indicate that TPACK has a partial mediation effect on the relationship between school support and the use of technology. The contribution of this study lies that it examines the complex relationships between internal and external factors affecting teachers' technology integration, especially among Mongolian teachers who are less researched in the existing literature.

The purpose of this study is to evaluate the temporal land cover change by gradual urbanization of Gyeongan-cheon watershed. This study used the five land use of Landsat TM satellite images(l987, 1991, 2001, 2004) which were classified by maximum likelihood method. The five land use maps examine its accuracy by error matrix and administrative district statistics. This study analyze land use patterns in the past using time.series Landsat satellite images, and predict 2004 year land use using a CA-Markov combined CA(Cellular Automata) and Markov process, and examine its appropriateness. Finally, predict 2030, 2060 year land use maps by CA-Markov model were constructed from the classified images.
