BACKGROUND AND OBJECTIVES: Recently developed laser lipolysis systems have been disappointing because they require more time to remove the same amount of fat than other liposuction methods. A new Nd:YAG laser has been introduced that uses the 1,444 nm wavelength, better absorbed by fat. STUDY DESIGN/MATERIALS AND METHODS: This study consisted of two protocols. The first protocol was an in vivo minipig model. Four 10x10 cm(2) areas were treated on the back of the first minipig. Using the same tot

This study presents a Korean writing course development of academic purpose for Chinese students who are going to study at a university in Korea. A final course model was developed through needs analysis, planning goals, course planning and syllabus design, implementation, evaluation and revising the model. A questionnaire, an interview and learners’ texts analysis were executed for needs analysis, as a result, it was found that learners did not have relevant writing skills and knowledge of text

PURPOSE: (CO) on human corneal epithelial (HCE) cells, a murine experimental dry eye (EDE) model, and the efficacy of antioxidant eye mask in dry eye disease (DED) patients. METHODS: 0.001%, 0.01%, and 0.1% CO extracts were used to treat HCE cells, cell viability, and production of antioxidative enzymes, and reactive oxygen species (ROS) were assessed. Afterwards, CO extracts or balanced salt solution (BSS) was applied in EDE. Clinical and experimental parameters were measured at 7 days after tr

The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.

본 연구는 다양한 의견을 담은 댓글에 노출되었을 때 그 댓글을 어떻게 지각하는지에 따라 이슈에 대한 여론지각의 방향이 어떻게 변화되는지 검증하였다. 이를 위해 인터넷 사용자(N=329)를 대상으로 이슈에 대한 찬ㆍ반 의견이 5:5로 구성된 뉴스 댓글 모음을 보여주고 이슈에 대한 여론을 어떻게 지각했는지 측정하는 실험 서베이를 실시하였다. 연구 결과 첫째, 사람들은 여론지각 시 본인에게 우호적인 방향으로 지각하는 ‘거울반사지각’ 경향을 보였다. 또한 의견강도가 강한 집단이 약한 집단보다 여론을 자신의 의견과 같은 방향으로 지각하는 경향이 더욱 강하게 나타났다. 둘째, 사람들은 댓글의 논조도 본인에게 우호적인 방향으로 지각했다. 그러나 여론지각과는 달리 의견강도에 따라 논조지각의 정도가 달라지지는 않았다. 셋째, 댓글을 읽는 행위는 여론지각의 ‘거울반사지각’ 경향을 다소 완화해준다는 것이 발견되었다. 특히, 댓글의 논조를 적대적으로 지각한 사람들은 기존과 반대 방향으로 여론지각을 변화시

Intrapartum ultrasonography serves as a valuable tool for the objective evaluation of labor progression and effectively identifies underlying factors, such as asynclitism, in cases of abnormal labor progression. Among the various ultrasound measurement techniques, the angle of progression (AOP) demonstrates favorable reproducibility and accuracy in assessing fetal head descent. In the context of abnormal labor, interventions differ across different stages of labor, emphasizing the importance of

A recently developed treatment strategy for lung cancer that combines immune checkpoint inhibitors with chemotherapy has been applied as a standard treatment for lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC), and it has improved the outcomes of chemotherapy. Maintenance treatment with anti-PD-1 antibody (aPD-1) enhances the effect of immunochemical combination therapy and improves therapeutic efficacy, which contributes toward a significant improvement in patient survival ra

연구는 2004년부터 2013년까지 10년 간 방영된 TV 드라마 중 연상연하커플이 등장하는 10편을 중심으로 연하남 및 연상녀의 외양적 조건과 역할, 커플 성사 과정및 여성의 성장 과정 등을 분석하였다. 연하남은 준수한 외모, 배려심, 중산층 이상의 부유한 배경 및 전문직을 갖고 있으며, 연상녀는 귀엽고 순수하게 그려져 전통적성역할 묘사에서 많이 벗어나지는 않았다. 단 여성의 외모, 성격은 남성보다 다양하고 현실적이었으며, 삶과 직업에 대해 고민하는 모습 등이 제시되어 전통적 여성상묘사보다 진보된 측면이 있다. 커플은 성사 과정에서 부모의 반대에 부딪히는데 반대 사유는 가부장적 젠더 이데올로기에 기대고 있다. 남녀 주인공은 이에 저항하지만 드라마가 제시하는 행복한 결말은 결국 전통적 남성성이 주는 안정에 편입한 것으로 귀결된다. 그러나 극을 이끄는 또 하나의 큰 축인 ‘여성의 성장’ 측면을 바라봤을 때 여성은 자신 혹은 직업이 부정당하는 시련을 겪게 되고, 각성을 통해 자신과직업에

We reviewed the current oral health status, the use of dental health services, and the factors that impede access to dental care for disabled people in South Korea and aimed to suggest the future direction of the dental community for establishing the right to oral health for the disabled people. Disabled people experienced more and faster teeth loss than non-disabled people due to the lack of proper oral hygiene management. The rate of not receiving proper dental prosthodontic treatment for the

Abstract The development of ionic materials with high ionic conductivity and mechanical strength is challenging. This study presents a novel synthetic strategy for the development of a mechanically robust and ionically conductive polyampholyte elastomer based on ionic dimers (IDs) with strong ionic bonds between imidazolium and sulfonate. Polymerization of ID monomers with a network that forms a cross‐linking moiety results in a novel polyampholyte ID elastomer (IDE). The addition of lithium (Li

Despite great progress in developing mode-selective light emission technologies based on self-emitting materials, few rewritable displays with mode-selective multiple light emissions have been demonstrated. Herein, we present a rewritable triple-mode light-emitting display enabled by stimuli-interactive fluorescence (FL), room-temperature phosphorescence (RTP), and electroluminescence (EL). The display comprises coplanar electrodes separated by a gap, a polymer composite with FL inorganic phosph

Background: Ptosis and volume atrophy of the breasts are common symptoms for various ages of women and may induce a considerable amount of stress in daily life. Periareolar augmentation mastopexy is an effective procedure for such conditions, and planning the new nipple position is very important. Aim: To provide a simple, straightforward planning and walkthrough of this operation in a journey to find the ideal level of breast lifting for natural upper fullness. Materials and methods: From Janua

BACKGROUND: Skin cancer is the most common malignant tumor in humans. Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the two most common types of skin cancers. When skin cancer is clinically suspected, preoperative biopsies are recommended for a definite diagnosis. However, despite a concern over potential increased risk of metastasis associated with mechanical manipulation, there have been few investigations into whether a preoperative biopsy affected the recurrence of BCC and
