Mitigation of Language in Post-Observation Conferences Between Two Peer Teachers

YeonJoo Jung 한국응용언어학회 2018 응용 언어학 Vol.34 No.3

This qualitative study examined the patterns of utterance-level mitigation strategies employed by peer teachers in the formulation of the suggestions and advice provided during a post-observation conference (POC) after peer observation of teaching (POT). Two peer teachers, who were serving as instructors for undergraduate level courses at the same university, participated in this study. Over a period of one semester, one of the two teachers observed the other teacher’s class two times, focusing on the agenda determined in the pre-observation conference. After each class visit, the observing teacher and the observed teacher had a POC in order to discuss the lesson in terms of the problems, strengths, possible future improvements. Findings showed that both the observing teacher and the observed teacher used a range of mitigating devices to protect each other’s positive and negative face. This suggests that despite the peers’ close relationship with balanced power, they were aware of the potential threat to face and the need to employ language mitigating strategies to maintain each other’s face in the POCs.

The Role of Explicit Instruction in Learning L2 Grammar Through an Interactive Language Task

YeonJoo Jung 한국응용언어학회 2019 응용 언어학 Vol.35 No.1

This study examined the effect of explicit instruction on the acquisition of second language (L2) grammar when it is presented to L2 learners before carrying out an interactive language task. In particular, this study investigated the role of explicit instruction in drawing learners’ attention to the target linguistic form (i.e., noticing) during peer interaction and facilitating the learning of the relevant structure. The target grammatical structure was the object-of-preposition type of relative clauses (RCs). The current study employed a pretest-posttest design with 32 English as a Second Language (ESL) learners who were randomly assigned to either an interactive task with explicit instruction (+EI) group or an interactive task alone (-EI) group. Learners participated in a pretest, a treatment session, and a posttest. Learners’ implicit and explicit knowledge of the target structure was measured using a grammaticality judgment task and a sentence completion task, respectively. Results indicated that explicit instruction did not necessarily lead to greater instances of noticing and that explicit instruction was beneficial for acquiring explicit knowledge but not implicit knowledge.

목적 본 연구에서는 핸드트래킹 기법을 활용하여 한국어 학습자들이 주격 관계절과 목적격 관계절이 포함된 문장을 처리할 때에 나타나는 비대칭성을 검증하고자 하였다. 방법 이를 위하여 미국에 거주하는 한국어 학습자들을 대상으로 반응 시간, 답변의 정확성, 최대 편이(Maximum Deviation), 곡선하 면적(Area Under the Curve), x축(x-flips)과 y축(y-flips) 상에서의 손의 움직임 등을 통해 언어처리 과정을 추적하였다. 이를 통해 한국어 학습자들이 주격/목적격 관계절을 처리할 때 인지적 부담에 따른 비대칭성이 표출되는지를 알아볼 수 있다. 결과 연구 결과에 따르면 핸드트래킹 기법에 포함된 여러 측정도구들 중 반응속도, 답변의 정확도 등을 통해 제2언어로서 한국어를 처리할 때 주격/목적격 관계절의 비대칭성이 나타남이 증명되었다. 결론 본 연구의 결과는 주격/목적격 관계절 문장처리 상의 비대칭성이 제2언어로서의 한국어에도 존재한다는 실험적 증거를 제시함과 동시에 구조거리가설과 명사구접근가설이 주격/목적격 관계절의 비대칭성을 설명하는데 유효하다는 주장을 뒷받침하였다. Objectives The aim of this study was to uncover the potential subject/object asymmetry in the processing of relative clauses (RCs) in the acquisition of Korean as a second language (L2), using a novel online processing method. Methods Potential differences between the processing of subject RCs and object RCs in L2 Korean were investigated using newer on-line mechanisms that measure motor movement related to maximum deviation, area under the curve, x-flips, and y-flips along with traditional on-line mechanism such as response time and accuracy rates. A total of 20 participants including 10 native Korean speakers and 10 L2 Korean learners were included in the experiment. Results Among those measures used to uncover the potential asymmetry in the processing of subject and object RC, only the analyses of RT and accuracy rate data yielded significant findings that support the subject advantage in RC processing in L2 Korean. Conclusions Findings of this study adds new empirical evidence to the literature, which suggests that the subject/object asymmetry in the processing of RC exists crosslinguistically, both in L1 and L2, regardless of typological differences of the target languages. Theoretical implications of the findings are discussed.

사용빈도에 기반한 스마트폰의 문장부호 및 특수문자 입력 레이아웃의 개선

정연주(Yeonjoo Jung),방지현(Jihyun Bang),김신우(ShinWoo Kim) 한국HCI학회 2013 한국HCI학회 학술대회 Vol.2013 No.1

최근 스마트폰의 사용 빈도가 높아짐에 따라 터치스크린을 통한 텍스트 입력 작업 또한 빈번하게 되었다. 그러나 스마트폰의 터치스크린은 기존의 물리적인 입력 디바이스들과 달리 상대적으로 큰 제한점들을 가지고 있다. 이로 인해 사용자들은 문자를 입력하는 과정에서 빈번한 오류를 범하게 되었다. 특히 스마트폰 기종마다 동일한 구조를 갖는 한글, 영문 텍스트보다 문장부호나 특수문자의 입력에서 오류가 자주 발생한다. 본 연구에서는 이러한 문제점을 개선하기 위해 문장부호 및 특수문자가 더 효율적이고 정확하게 입력되려면 텍스트 레이아웃이 어떠한 구조를 가져야 하는지에 대해 연구하였다. 설문조사를 통해 스마트폰 사용자들의 기호 사용 패턴을 조사하여, 문장부호 및 특수문자의 사용빈도 자료를 획득하였다. 더불어 입력 레이아웃을 몇 가지 세부 영역으로 구분하여 각 영역에서 CPS(초당 문자 입력 수)를 구하여 가장 입력속도가 높은 영역이 어디인지를 지정한 다음, 이에 배치하여야 하는 기호들은 어떤 것들인지를 파악하였다. 본 연구에서 재구성한 대안적 레이아웃과 기존 제품의 레이아웃을 CPS를 비교분석하면서 사용성을 높일 수 있는 입력 레이아웃을 제안하였다. Recent popularity of smartphones resulted in frequent use of touchscreen for text input. However, touch-based input has a number of limitations compared with previously used physical input methods. As a result, users tend to make more errors when they enter text using those devices which adopt more advanced technology. In particular, more errors appear to occur when people enter punctuation marks and special characters compared with Korean/English characters which has similar layout across different smartphones. In order to address this issue in this research, we investigated how the input layout has to be arranged in order to support more efficient and accurate input of punctuation marks and special characters. Using survey of smartphone users’text input pattern, we obtained frequency data of punctuation marks and special characters. Then we divided input layout into three areas in which each area has different CPS(input per second) in order to assign different marks and characters based on their frequency. We propose an alternative input layout while comparing previous vs. our newly designed input layout in this research.

Extending previous research on collaborative priming tasks and task repetition, the study investigated the impact of task and procedural repetition on eliciting target grammatical structures during collaborative priming tasks. It employed a pretest-posttest design with 57 Korean high school students who were randomly assigned to one of three groups: a control, priming with task repetition, and priming with procedural repetition. Learners participated in a pretest, two priming sessions, and two posttests over a 4-week period. Learners’ ability to produce target grammatical structures was measured through story-telling tasks. The task repetition group repeated the same primes and prompts twice, whereas the procedural repetition group performed priming tasks with different primes and prompts during two sessions. Results indicated that repeating the same primes and prompts facilitated learners’ production of two types of relative clauses, which in turn promoted their learning of these structures over time. Implications are discussed in light of the benefits of collaborative priming tasks in helping L2 learners develop L2 grammar.

<P><B>Summary</B></P> <P>We report proteogenomic analysis of diffuse gastric cancers (GCs) in young populations. Phosphoproteome data elucidated signaling pathways associated with somatic mutations based on mutation-phosphorylation correlations. Moreover, correlations between mRNA and protein abundances provided potential oncogenes and tumor suppressors associated with patient survival. Furthermore, integrated clustering of mRNA, protein, phosphorylation, and N-glycosylation data identified four subtypes of diffuse GCs. Distinguishing these subtypes was possible by proteomic data. Four subtypes were associated with proliferation, immune response, metabolism, and invasion, respectively; and associations of the subtypes with immune- and invasion-related pathways were identified mainly by phosphorylation and <I>N</I>-glycosylation data. Therefore, our proteogenomic analysis provides additional information beyond genomic analyses, which can improve understanding of cancer biology and patient stratification in diffuse GCs.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Mutation-phosphorylation correlation suggests possible signaling interplays in EOGCs </LI> <LI> mRNA-protein correlation suggests genes with high association with patient survival </LI> <LI> Integrated analysis of mRNA and protein data identified four subtypes </LI> <LI> Phosphorylation data provide cellular signaling pathways underlying the subtypes </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>

Introduction: In-hospital cardiopulmonary-resuscitation (CPR) is one of the disastrous situations. There are concerns whether patients in a palliative phase of cancer are the candidate for CPR or not. The avoidance of unnecessary CPR is important issues in palliative care of cancer. Methods: We reviewed medical records of division of hematology and medical Oncology, department of Internal Medicine in Seoul National University Bundang Hospital and analyzed characteristics of CRP situations from March 2003 toJune 2015. Total a 137 patients with cancer happened cardio-pulmonary- arrest and were given CPR including cardiac massage, intubation, DC cardioversion and intensive care unit treatment. We used modified pre-arrest morbidity (mPAM) score to evaluate medical conditions which result in arrest. Results: The mean age was 67 years (range, 39 99). Eighty eight patients (64.2%) were men and 50 patients (36.4%) were women. The primary malignancies were acute leukemia in 13 patients (9.4%), lung cancer in 40 patients (29.1%), lymphoma in 20 patients (14.6%), gastric cancer in 23 patients (16.7%), and other tumor type in 42 patients (30.2%). The causes of arrest were asphyxia from pulmonary aspiration in 15 patients (10.9%), cancer-related bleeding in 21 patients (15.3%), infection related chemotherapy in 23 patients (16.7%), infection not-related chemotherapy in 13 patients (9.4%), cancer progression in 33 patients (24.0%) and other causes in 34 patients (24.8%). The mean of mPAM score was 1.35. The 52 patients (37.9%) were given unnecessary CPR. Of unnecessary CPR, their relatives wanted resuscitation in 4 (2.9%). 85 patients (62.0%) received necessary CPR because they were on chemotherapy cycle or had chemotherapy plans. However, first return of spontaneous circulation (ROSC) rate was 43.7%, but re-arrest happened to most of them. So in-hospital survival rate was 8.7%. Discussions: The prognosis in patients who received CPR in palliative care of cancer was poor. Therefore, we should make an effort to avoid arrest events.

본 연구는 자존감과 조건부 자존감 수준에 따른 SNS 이용동기와 중독경향성의 차이를 살펴봄으로써 적응적인 SNS 이용을 돕고 SNS 중독경향성을 감소시키기 위한 개입 방안을 마련하는 기초자료를 확보하는데 주 목적이 있다. 이를 위해서 SNS 중에서도 인스타그램을 사용하는 대학생 471명을 대상으로 자존감, 조건부 자존감, SNS 이용동기 및 중독경향성 척도를 실시하였고, 군집분석 및 일원변량분석을 통해 분석하였다. 분석결과, 첫째, 자존감과 조건부 자존감 및 SNS 중독경향성 간에는 부적 상관관계가 나타났고, 조건부 자존감은 SNS 이용동기와 중독경향성 간에 정적 상관관계를 나타냈다. 둘째, 자존감과 조건부 자존감 수준에 따라 ‘안정된 높은 자존감’ 집단, ‘불안정한 높은 자존감’ 집단, ‘자존감 중간’ 집단, ‘불안정한 낮은 자존감’ 집단의 4개 군집이 도출되었다. 셋째, 각 군집별 SNS 이용동기의 차이에서 불안정한 높은 자존감 집단의 대인관계동기와 정보동기 수준이 다른 집단에 비해 높게 나타났으며, SNS 중독경향성에서는 불안정한 높은 자존감 집단과 불안정한 낮은 자존감 집단이 다른 집단보다 높게 나타났다. 본 연구는 SNS 이용 및 중독경향성에 대한 문제를 경험하는 내담자와의 상담 장면에서 실질적인 개입 방안을 마련하는 데에 도움이 될 것으로 기대한다. This study aimed to explore differences in SNS users’ motivation and SNS addiction tendencies, as based on both self-esteem and contingent self-esteem. A total of 471 students who used Instagram were recruited. The results were as follows: first, there was a significant correlation among self-esteem, contingent SNS users’ motivation, and SNS addiction tendencies. Second, four cluster types were found relating to the level of self-esteem and contingent self-esteem: “stable high self-esteem,” “unstable high self-esteem,” “unstable low self-esteem,” and “moderate self-esteem.” Third, “stable high self-esteem” type showed differences on motivation and addiction tendencies, and “unstable high self-esteem” and “unstable low self-esteem” types showed high addiction tendencies. This study can provide useful information on people experiencing SNS problems so that counselors may find strategies to decrease SNS addiction tendencies.

Recently, there has been a need to improve the performance of the dust collector by increasing the fine dust pollution in Korea. In this study, electrostatic spray wet electrostatic precipitator is used to remove Particulate Matter (PM). In order to enter the Cone-jet mode, which is the most stable spray mode among the various modes of electrostatic spraying, an appropriate voltage-flow condition must be satisfied, and a voltage-flow interval enabling this can be expressed as Stability Island. The voltage at which the conduit mode starts in the Stability Island section is referred to as the electrostatic spray minimum voltage (Onset Voltage). The electrostatic spray minimum voltage is affected by the nozzle radius, surface tension, distance from the nozzle to the dust collector, and the field strength is induced by internal pressure, surface tension pressure and normal stress tensor equilibrium. However, the conventional electrostatic spray minimum voltage equation does not consider gravity variables. In this study, the difference between the case where the nozzle and the dust collector were arranged vertically and the case where the dust collector was arranged horizontally was studied considering the gravity variable.
