손쉽게 현 위치 정보를 공유하고 사용자 간 커뮤니케이션이 가능한 위치 기반 소셜 네트워크가 대중화되면서 장소 추천에 대한 연구가 활발히 진행되어 있다. 본 논문은 시간대별 사용자 선호도와 주요 활동 영역을 고려한 POI 추천 기법을 제안한다. 장소 카테고리별 사용자의 체크인(che-ck-in)정보를 시간대로 분할하여 시간에 따른 장소의 선호도를 판별하고 사용자의 과거 이력을 이용하여 사용자별 활동 영역을 선별한다. 장소의 선호도와 선별된 활동 영역에 기반하여 협업 필터링을 수행하여 POI를 추천한다.

의복은 인간이 삶을 영위함에 있어 필수불가결한 요소인 ‘의식주’의 하나로서 생산 및 유통의 역사는 인간의 역사와 같이한다. 인간의 개성 추구와 더불어 의복은 인간을 외부로부터 보호해 주는 기능적인 면에서 자신을 표출하는 패션적인 면이 더욱 강조되는 경향을 발전하고 있다. 의류부문에서 물류의 기능은 다른 제품과 마찬가지로 제품의 출하되는 원상태로 유지하면서 소비자가 원하는 시간에 원하는 장소에서 인도될 때 완전한 물류서비스를 제공하는 것이 된다.(중략)

With the development of location-aware technologies and the activation of smart phones, location based social networks(LBSN) have been activated to allow people to easily share their location. In particular, studies on recommending the location of user interests by using the user check-in function in LBSN have been actively conducted. In this paper, we propose a location recommendation scheme considering time and user activities in LBSN. The proposed scheme considers user preference changes over time, local experts, and user interest in rare places. In other words, it uses the check-in history over time and distinguishes the user activity area to identify local experts. It also considers a rare place to give a weight to the user preferred place. It is shown through various performance evaluations that the proposed scheme outperforms the existing schemes.

Cavity is inevitably included in automobile vehicle configuration. The complex unsteady flow and sound waves generated by the cavity are very important issues because of the involved fluid dynamics and the practical importance in the field of aerodynamics. The LES method used is a conventional one with Smagorinsky eddy-viscosity model and the computational grid is small enough to be handled by workstation-level computers. LES can successfully simulate of cavity noise analysis.

인터넷의 발달로 인해 이제는 집에서 PC로만 해오던 게임을 언제 어디서든 인터넷만 가능하다면 게임을 즐길 수 가 있게 되었다. 이 게임은 웹의 편리함과 자바의 애플릿 기술을 이용하여 인터넷 온라인 게임을 설계 및 구현하였다. 웹 상에서 이루어진다는 편리함을 가지고 있지만, 시간과 장소의 제약이 크고, 동시에 여러 사람 이 함께 게임을 할 수 없다는 단점을 가지고 있다. 본 논문에서는 모듈기반의 벽돌깨기 게임을 개발 및 구현하였다. 시스템 분석 및 설계에서는 UML을 이용하였으며, 자바 애플릿으로 구현하여 웹 상에서도 이용 가능하였다.

Purpose: This study empirically investigates the utilization and expenditure of health care and long-term care at the last year of life for long-term care beneficiaries in Korea. Methods: This study used National Health Insurance and Long-term Care Insurance claims data of 271,474 LTCI beneficiaries, who died from July 2008 to December 2012. Their cause of death, place of death, health care costs, and the provision of aggressive care were analyzed. Results: Cardio-vascular disease(29.8%) and cancer(15.3%) were reported as their major cause of death, and hospital(64.4%), home(22.0%), social care facility(9.2%) were analyzed as the place of death. 99.3% of subjects used both health care and long-term care during the last 1 year of life. The average survival period were 516.2 days after they were LTCI beneficiaries. The health care expenditure gradually increased near the death, and the last month were three times more rather than the first month. Furthermore, 31.8% experienced some aggressive cares(CPR, blood transfusion, hemo-dialysis, etc.) at the last month of life. Conclusion: The results of this study suggest that it is important to develop the end of life care policies(for example, hospice, advanced care directives) for the LTCI beneficiaries. They might contribute to the improvement of quality of life and the reduction of health care expenditure of the elderly at the end-of-life.

The purpose of this study is to examine whether there is a difference in the awareness of death based on happiness (since attitude or way of life differs among the general public, depending on the perception of death), and to investigate whether there is a difference in the interest in hospices between a group with a high happiness index and a group with a low happiness index. A survey was conducted on 200 men and women aged over 20 who participated in a walking event held in a metropolitan city on April 22, 2017. The survey consisted of eight demographic items: gender, age, education, occupation, marital status, family cohabitation, religion, and health status. It included 29 questions regarding happiness and nine questions regarding the perception of death. For the statistical tests, a chi-square test, an independent sample t-test, correlation analysis, and canonical correlation analysis were performed on the items of the survey based on a happiness index. The results of the study showed that, for a suitable place for death, medical institutions was the highest score (46.3%) for the group with a low happiness index, and own house was highest (59.4%) for the group with a high happiness index. This was a significant difference. It is thought that management systems should be supplemented by professional manpower, educating people so as to increase the utilization rates of home-based hospice as a way for patients to die in a comfortable and familiar place because, for Korea, death is much more common in hospitals. It is also necessary to increase the awareness of death and to make effective use of hospices through individual and various other approaches, considering the demographics of the subjects.

The Olin Library in St. Louis was an important design competition for the United States in the 1950's, the rear of America's modern architecture. The participants of this competition were a variety of representative architects and groups of its time. With the library's functional rationality, the Olin Library competition was legible of the aspects of modern architectural flow. The competition required two demands. The first demand was absolute importance in character definition of place, which was to satisfy the site conditions approached from campus design. Secondly was related to interpretation of morphological symbolism in an architectural matter. The experiments of American modern architecture started to change its ideal goal gradually ; accommodating the altering public's code, at the same time, maintaining the original modern value was the reason to changing the ideal goal. As a turning point, the Olin Library should be understood as an important work, which divulged the value change of architectural interpretation.

Purpose: Even though there have been various efforts for the dying with dignity of terminal patients, no researches focused on the public attitudes. Methods: In February 2004, we sampled 1,055 persons over 20 years of age from the sixteen cities and local districts of Korea through the quota sampling method according to their gender, age, and location. We conducted a telephone survey with a structured questionnaire on the attitudes toward dying with dignity and hospice palliative care. Results: The most important conditions for the dying with dignity on the patients' views were 'removing burdens for other people' (27.8%). Over the half of the samples chose their home as a preference for place of death (54.8%). 82.3% of the respondents agreed to the idea of withdrawing the medically futile life-sustaining treatment. Fifty seven percents of the answered public said that they intended to use the hospice service in case of terminal illness. Eighty percents thought that health care insurance should cover hospice service, and 80.9% gave positive response to the necessity of advance directives. Respondents emphasized 'the financial support for the terminal patients' (29.8%), 'covering hospice service with health insurance' (16.5%), and 'the education and public relation for settlement of desirable dying culture and hospice service' (15.9%) as the roles and responsibilities of the government for the dying with dignity. Conclusion: This study shows that there is a possibility of significant consensus on hospice and palliative care system for the dying with dignity of patients and reduction of the suffering for their families among the general public.
