Mucosa-Associated Lymphoid Tissue Lymphoma of the Labial Minor Salivary Glands: Case Report

이정은,한다울,김현실,이채나,박연정,권정승 대한안면통증∙구강내과학회 2024 Journal of Oral Medicine and Pain Vol.49 No.1

A 74-year-old female presented with a complaint of dry mouth, continuous spontaneous burning sensation in the tongue, and asymptomatic submucosal soft tissue mass on both sides of the lower labial mucosa. She refused to undergo total excision of the mass due to concern about the possibility of complications such as nerve damage because of the large size of the mass. As her clinical features and magnetic resonance imaging indicated the possibility of Sjögren’s syndrome, a biopsy of the minor salivary gland of the right lower lip was performed. Consequently, she was diagnosed with mucosa-associated lymphoid tissue (MALT) lymphoma. Although the patient had typical signs and symptoms of Sjögren’s syndrome, the histopathological result of MALT lymphoma made it impossible to determine whether the patient had a history of Sjögren’s syndrome. For patients with risk factors for MALT lymphoma, such as Sjögren’s syndrome, a biopsy of the labial minor salivary gland with immunohistochemical staining can be helpful in the diagnosis of not only Sjögren’s syndrome but also MALT lymphoma.

Purpose: The screening test for colorectal polyp is important for the early detection and prevention of colorectal cancer. The aims of this study were to evaluate the characteristic findings and the anatomical distribution of colorectal polyps observed during colonoscopy and to determine proper screening candidates to undergo colonoscopy for colorectal cancer. Methods: From March 1999 to February 2004, 3,454 asymptomatic individuals underwent total colonoscopy. The number, the location, and the histology of polyps were evaluated retrospectively in 634 patients who had colorectal polyps (453 males and 181 females). The relations among age, location, and histology were analyzed. Results: The mean age was 60 years (range, 15 to 95). Four hundred and twenty-two patients (67%) had a single polyp, and 212 (33%) had two or more polyps. Left-sided polyps were observed in 422 patients (67%), right-sided polyps in 134 patients (21%), and synchronous both-sided polyps in 78 patients (12%). Adenomas were present in 387 patients (61%), and adenocarcinomas were detected in 47 patients (7.4%). There was no definite correlation between location and histology. However the prevalence of right-sided polyps increased with age (P<0.01). Conclusions: More than 30% of the polyps were located proximal to the splenic flexure. Thus, in the absence of left-sided lesions, an examination of the colon that is limited to the splenic flexure might miss 21% of such lesions. The increasing prevalence of right-sided polyps with age suggests that evaluation of the proximal colon is particularly important in the elderly, especially in those older than 60 years.

이정은 한국교원대학교 유아교육연구소 2013 한국유아교육연구 Vol.15 No.2

The purpose of this study is to examine the characteristics of young children’s narratives appearing by interacting with their peers while playing with blocks. The subjects include 7 five-year-olds of the Class attending the kindergarten. I collected a variety of data relating a play with blocks through observation in order to understand the content and structure of narratives. Gathered information was closely examined through a qualitative study to find out how children build narratives. The major research found that during block play, the children made a structure related to their life and recreated their experience using it as a background. The characteristics of young children’s narratives are categorized into the following three types: a children’s life story; imaginary story; and mixed story of both the real world and the imaginary world. Young children gave meanings to what they have built with the blocks through sharing their stories and came up with stories that are based on their life experience, knowledge, and imagination. 본 연구는 유치원의 자유선택활동 중에서 유아들이 쌓기놀이를 하는 과정에서 놀이의 구성물을 통하여 또래와의 상호작용을 하면서 나타나는 내러티브 내용 특징을 알아보는데 있다. 참여유아는 만 5세반 유아 7명이며 유아의 내러티브 내용과 조직을 심층적으로 이해하기 위해 참여관찰을 통해 쌓기놀이에 관련된 내러티브와 관련된 자료들을 수집하였다. 수집된 자료들을 통해 유아들이 어떠한 내러티브를 만들어 가는지 질적연구 방법을 통하여 분석하였다. 연구결과 유아들은 쌓기놀이의 과정에서 그들의 삶과 관련이 있는 구조물을 만들고 놀이의 배경으로 이용하여 경험을 재현하고 다양한 내러티브를 만들었다. 유아들이 만든 내러티브는 유아들의 생활이야기, 상상이야기, 현실과 상상이 혼합된 이야기로 구분되어 졌다. 유아들은 쌓기놀이를 하면서 서로의 이야기를 나누는 과정을 통해 만들어진 구조물에 의미를 부여하고 생활세계의 경험과 지식, 상상력을 기초로 이야기를 만든다.

이정은,최연실 한국가족치료학회 2014 가족과 가족치료 Vol.22 No.1

Objectives: This study developed and tested a solution-focused group counseling program as an intervention for elementary school students presenting symptoms of Internet addiction. The program was designed to improve the students’ self-esteem and ability to cope with stress. Method: The participants were six 6th grade students identified as being at risk of Internet addiction. The students participated in a total of eight 90-minute sessions of solution-focused group counseling. The researchers performed the Mann-Whitney U Test and the Wilcoxon Signed-Ranks Test to determine whether the counseling program was effective. Results: The solution-focused group counseling program was found to improve the students’ self-esteem and ability to cope with stress. Conclusions: Despite the fact that most of the students in the group counseling program did not voluntarily participate, the results demonstrated that the students' short-term and positive characteristics, such as the ability to solve problems, improved as a result of their involvement in the program. 본 연구의 목표는 인터넷중독 증후를 보이는 초등학생의 자존감 및 스트레스 대처능력을 향상시키기 위해 해결중심 집단상담 프로그램을 구성하고 그 효과성 검증을 통해 인터넷중독에 대한 개입 방안을 제시하고자 하는 것이다. 이를 위하여 인터넷중독 위험군으로 분류된 초등학교 6학년 학생 6명을 대상으로 주 1회 90분씩 총 8회기의 해결중심 집단상담 프로그램을 진행하였다. 본 연구의 효과성 검증을 위해 SPSS 18.0을 이용하여 Mann-Whitney U Test와 Wilcoxon Signed-Ranks Test를 통한 양적 분석과 Colaizzi의 연구방법을 이용한 질적 분석을 실시하였다. 본 연구 결과, 해결중심 집단상담 프로그램은 인터넷중독 초등학생의 자존감과 스트레스 대처능력을 향상시키는 데 효과가 있는 것으로 나타났다. 본 연구는 해결중심치료모델이 지니고 있는 단기적 특성, 그리고 내담자를 이미 문제해결력을 가진 존재로 보는 것과 같은 내담자 중심의 긍정적 특성 등으로 인해, 그 치료모델이 상담 상황에 대부분 비자발적으로 참여하게 되는 인터넷중독 초등학생에게 활용 가능하고 기여할 수 있음을 입증한 데에 그 의의가 있다.

The study of cancer in patients treated with dialysis in Korea has not been reported. The aim of this study was to investigate the incidence and mortality of cancer among patients on dialysis in Korea. The study subjects were 106 cancer patients (2.3%) out of 4,562 end-stage renal disease (ESRD) patients maintained on hemodialysis (HD) or peritoneal dialysis (PD) at Yonsei University Health System from 1996 to 2005. We excluded patients in whom the diagnosis of cancer preceded dialysis or those who received renal allograft or started dialysis after renal allograft. Seventy- three (69%) of our subjects were male and 33 (31%) were female. The mean age at the time of cancer diagnosis was 57.9±11.7 yr. The mean time from the start of dialysis to the diagnosis of cancer was 75.2±63.9 months. The most common cancer site was gastrointestinal tract (GIT) (51%) followed by urinary tract (20%), lung (8%), and thyroid (7%). Sixty nine percent of the total mortality was due to cancer. The mean time from diagnosis to death was 2.9±2.5 yr. In ESRD patients with cancer, there were no significant differences in mortality rates by dialysis modality. In ESRD patients, the most common cancer was GIT cancer followed by urinary tract cancer. Therefore, careful surveillance of these cancers in ESRD patients is highly recommended.

Effects of $SiO_x$ or C shells on electrochemical properties of Si nanoparticles were investigated. $SiO_x$ shells with thickness of 10~15 nm were formed on homogeneously crystalline Si nanoparticles. Incase of Si-C nanoparticles, there were 30~40 layers of C with a number of defects. Li-ion batteries were fabricated with the above-mentioned nanoparticles, and their electrochemical properties were measured. Pristine Si shows a high IRC (initial reversible capacity) of 2,517 mAh/g and ICE (initial columbic efficiency) of 87%, but low capacity retention of 22%, respectively. $SiO_x$ shells decreased IRC (1,534 mAh/g) and ICE (54%), while the retention increased up to 65%, which can be explained by irreversible phases such as $LiO_2$ and $Li_2SiO_3$. C shells exhibited no differences in IRC and ICE compared to the pristine Si but an enhanced retention of 54%, which might be from proper defect structures.

재판과정에서 공판검사의 인권친화적 태도: 법정 모니터링을 통한 인상분석을 중심으로

이정은 한국인권학회 2020 인권연구 Vol.3 No.1

This paper attempts to empirically explain the meaning and influence of the language and behaviors of prosecutors through court monitoring. To this end, we analyze the attitudes of prosecutors by visiting the courts in Seoul, Gyeonggi, Gyeongnam, Jeonnam, and Jeju Island in person. This research uses the observation method among qualitative research methods and applies Erving Goffman's theory of impression management to the analysis. The third-party interpretation of verbal and nonverbal behaviors raises a question about what the essential roles of the prosecutor are. The attitudes of prosecutors are categorized into two ways: human rights-friendly attitude and trial performance capability. This paper argues that prosecutors have to understand each case in the broader social relations and contexts and put intentional efforts to protect the human rights of involved individuals. 이 글은 법정 모니터링을 통해 공판검사의 언행이 갖는 의미와 영향력을 분석하고 바람직한 공판검사상에 대한 실증적 분석을 시도하고자 한다. 이를 위해 서울・경기, 경남, 전남, 제주의 법정을 방문하여 공판검사의 태도를 분석하였다. 이 조사는 고프만의 인상관리 이론을 적용하여 질적연구방법의 관찰조사를 실시하였으며, 제3자에 의한 언어와 비언어적 행위의 해석은 공판검사의 본질적 역할이 무엇인지를 질문하고자 한다. 공판검사의 태도는 인권 친화적인 태도와 공판수행의 성실성, 신속성, 친절함의 공소 수행역량으로 나누어 검토하였다. 조사결과, 공판검사는 소송관계자의 인권보호를 위한 의도된 노력이 필요하고 공정한 재판을 받을 권리를 사회적 관계와 조건 속에서 인식해야 할 필요가 있다는 것을 제안하고자 한다.
