Objectives: This study aimed to develop and validate a model to predict the need for intensive care unit (ICU) admission in patients with dental infections using an automated machine learning (ML) program called H2O-AutoML. Materials and Methods: Two models were created using only the information available at the initial examination. Model 1 was parameterized with only clinical symptoms and blood tests, excluding contrast-enhanced multi-detector computed tomography (MDCT) images available at the initial visit, whereas model 2 was created with the addition of the MDCT information to the model 1 parameters. Although model 2 was expected to be superior to model 1, we wanted to independently determine this conclusion. A total of 210 patients who visited the Department of Oral and Maxillofacial Surgery at the Dankook University Dental Hospital from March 2013 to August 2023 was included in this study. The patients' demographic characteristics (sex, age, and place of residence), systemic factors (hypertension, diabetes mellitus [DM], kidney disease, liver disease, heart disease, anticoagulation therapy, and osteoporosis), local factors (smoking status, site of infection, postoperative wound infection, dysphagia, odynophagia, and trismus), and factors known from initial blood tests were obtained from their medical charts and retrospectively reviewed. Results: The generalized linear model algorithm provided the best diagnostic accuracy, with an area under the receiver operating characteristic values of 0.8289 in model 1 and 0.8415 in model 2. In both models, the C-reactive protein level was the most important variable, followed by DM. Conclusion: This study provides unprecedented data on the use of ML for successful prediction of ICU admission based on initial examination results. These findings will considerably contribute to the development of the field of dentistry, especially oral and maxillofacial surgery.

The development of urbanization in the twentieth century according to the rampant growth of industrialization not only brought about the improvement of life-quality but also induced us to reconsider the contemporary issues such as crisis of echo system which made us aware of the values and significance of the system and sustainable environments. As sustainability has been recognized as the holistic concept, it has been highlighted as one of the core concepts in the studies with the present ecological perspective. Particularly, as the plan of urbanization in Korea which had been based on the deconstruction has been converted into the regeneration, economic and cultural regeneration is also demanded for the future plan besides material regeneration. This study aims to scrutinize various attributes of socially sustainable designs in Yerba Buena Garden of San Francisco, USA which has been globally well known as a successful example of urban regeneration. By way of visit-and-observation of the place, the research for the study was conducted during the month of December, 2007. Three researchers visited Yerba Buena Garden to observe and take photographs and to obtain relevant data and public documents in local public library. Socially sustainable design was measured on the basis of such principles; social facilitation, permeability and accessibility, safely and emotional stability, softness and feminism, and child care convenience. Relevant data were systematically organized to support and prove the above principles. The result of the study is expected to effectively be utilized for Korean environment plan and design as a benchmarking guidelines against the crisis of degeneration and the aging society with the lowest birthrates in the world.

The value of all goods and services produced in the economy divided by population has risen from $7.355 in 1998 to $12.646 in 2003. In other to maintain higher standard of lifestyle, people are 'hungry' for time. The idea of saving time and money by providing many different types of products altogether in one space was implemented with the advent of large warehouse style discount stores. These type of retailers grew in size and popularity during the 1990s and 2000s, causing a decline in sales in the old, traditional downtown markets. From ancient to twenty-first century, the role of the grocery store has been that of the social center of the community; a place of unity and interaction of people. The experience a customer engages in at a grocery store is comparable to that of a museum. Not only is the grocery store a unique, physical space to visit, but also a rich collection of fascination items. The layout of the interior space is meticulously planned for the efficiency of customer circulation and the success of product exhibition. Eye catching graphics and attractive lighting also add to the appeal of the grocery store's high style. Shoppers are no longer satisfied with just buying good products at a lower price. Shoppers prefer to spend time in an entertaining environment. The Hanaro Mart project in this study propose the idea of warehouse style discount stores which can satisfy all the demands of customers and their various activities. This study will open up unique dimensions of aesthetic expression and experience in the interior environments. Shopping for food is an unavoidable task. If food shopping is enjoyable, more people will spend more time at it.

The numbers of the elderly who suffer Empty Nest Syndrome have been accelerated as an aging population has increased vastly and nuclear families have been a dominating family type in modern Korean society. To make the elderly get out of this phenomenon and live actively, the scheme of converting their existing houses into shared houses was set as a hypothetical solution in this study, and finding out the responses of the elderly who owns their own houses is the purpose of the study. A small workshop panel method was used and the elderly aged 55 years upwards took part and they own a detached house that is relatively large for the elderly or the elderly couple to live alone. The workshop was consisted of 3 stages: 1. a survey 2. an interview 3. a site visit. Through this, problems that the elderly have been experiencing within their houses were looked into and the responses of the elderly on converting their houses to shared houses by introducing developed schematic plans. As a result, positive responses from the house owners were carried out based on the fact that subsidies from the government on house renovation and tenants matching programs are supported. Shared houses could provide home owners economical support with rents and help them to feel less lonely. This is one way of supporting the elderly to live and age actively in their later lives. Therefore, this idea should be established in connection with preparing aging, aged, and super-aged society.

본 연구의 목적은 첫째 무드를 효과적으로 조성하기 위한 장르와 템포를 제시할 수 있으며, 둘째, 호텔 내 레스토랑과 테마 레스토랑 유형별 적합한 배경음악의 장르와 템포를 제시하여 호텔과 레스토랑 경영자들이 활용할 수 있도록 하는 것이다. 본 연구의 결과로부터 음악의 장르와 템포에 의해 고객의 무드에 영향을 미치고 만족 및 재방문, 추천의사에 유의한 영향을 준다는 사실을 확인할 수 있었다. 예를 들어 업장 분위기에 변화를 주고 싶다면 시간적, 금전적인 감수가 필요한 리모델링을 보다는 배경음악의 변화가 훨씬 용이할 것이며, 업장의 컨셉이 확정되었다면 그 컨셉을 더 표출해 줄 수 있는 것이 음악이며, 고객의 특정 감정에 호소하기 위해서는 본 연구에서 제시하고 있는 장르와 템포대로 곡을 선정할 수 있을 것이다. 예를 들어 편안하고 긍정적인 감정을 유발하기 위해서는 느린 템포를, 친숙하고 행복한 감정을 위해서는 중간 템포를, 기쁨과 호감을 위해서는 빠른 템포가 적합하다는 것이다. 편안함을 유발시킨 느린 템포는 고객의 업장 내에서의 체류시간 길게 할 것이며, 반대로 빠른 템포는 체류시간을 감소시킬 것이다. 이를 활용하여 좌석회전율을 높이기 위해선 빠른 템포의 음악 선정할 수 있을 것이다. 고객의 감정을 음악으로 조율하여 고객 만족과 재무성과의 목표를 동시에 달성할 수 있을 것이라는 사실을 제안한다.
