Research indicates that direct instruction of story grammar can improve reading comprehension of narrative texts. The purpose of this study is to investigate the effects of story grammar instruction on 5th grade EFL students’ comprehension of narrative texts using a story map. This study was conducted with 44 primary school students for 6 weeks. The students in the experimental group were taught to read four storybooks focusing on the story grammar. The data collected were used for quantitative and qualitative analysis. Results showed that the experimental group outperformed the control group(N=22) on tests. The qualitative analysis of four students’ story maps in the story grammar instruction group showed progress and positive changes in their ability to identify the global structure of a text and to abstract episodic sequence. Using story maps based on the story grammar provided students with a framework to organize and retain critical story elements that, in turn, enhanced comprehension. The findings indicate that direct story grammar instruction can be an effective way to improve reading as well as writing skills.

Tacrolimus (FK506)에 의해 유도된 세포 고사의 신호 전달 기전에 대한 연구

정미란(Mi Ran Jung),최수진나(Soo Jin Na Choi),정상영(Sang Young Chung) 대한외과학회 2007 Annals of Surgical Treatment and Research(ASRT) Vol.73 No.5

Purpose: This study examined the effects of Tacrolimus (FK506) on the expression of the apoptotic signal transduction proteins of Jurkat human T-lymphocytes. Methods: The cell viability was examined by a MTT assay, DAPI stain, enzyme activity of caspase family proteins, and western blotting for Bcl-2, Bak, Fas, and Fas-L. The cells were cultured in the presence or absence of FK506. FK506 induced cell death was confirmed to be apoptosis by the observation of nuclear fragmentation. Results: The viability of Jurkat cells was decreased by the addition of FK506 in a dose- and time- dependent manner. The FK506 induced activation of caspase-3 protease was observed. FK506 didn’t increase the catalytic activity of caspase -6, -8, and -9 proteases of Jurkat cells in a time-dependent manner. The viability was improved when a caspase-3 inhibitor was added. However, the caspase-9 inhibitor did not affect the viability. Bak protein expression was increased, and the Bcl-2 protein was decreased for some time. The expression of Fas and Fas-L were unaffected by FK506. Conclusion: FK506 induces dose- and time-dependent apoptotic cell death, and enhances the apoptosis of Jurkat cell by increasing the expression of Bak and caspase-3.

이 연구는 청소년의 학교급을 고려하여 자살생각에 관한 예측요인을 파악하고자 하였다. 이를 위해 전국 10개 시·도의 중?고등학생 399명을 대상으로 의사결정나무분석을 적용하여 자살생각의 예측요인을 분석하였다. 연구의 결과 첫째, 중?고등학생의 자살생각을 가장 효과적으로 예측하는 변인은 우울로 나타났다. 둘째, 중학생은 우울이 높으면서 자존감이 낮을 때 가장 높은 자살생각을 보였으며, 우울과 자존감이 높은 중학생의 경우 스트레스의 정도는 자살생각의 위험요인이자 보호요인으로 밝혀졌다. 셋째, 낮은 우울을 보이는 고등학생이 자신에 대한 부모의 관심이 낮다고 인식하는 것은 자살생각의 위험요인이 되며, 중간 정도의 우울이면서 높은 부모의 관심을 인지하는 경우에는 희망 수준이 자살생각의 위험요인 혹은 보호요인으로 예측되었다. 이러한 결과를 기초로 청소년의 자살을 예방하기 위한 실천적 함의를 도출하고 후속연구를 위한 제언을 하였다. This study was conducted in order to identify the predictors of suicidal ideation, depending on the level of school of adolescents. The participants were 399 middle(161) and high school(238) students sampled from 2 cities and 8 provinces nationwide. The data for the study were analyzed by means of decision tree analysis. The major results of the study were as follows. First, a main predictor of suicidal ideation for middle and high school students was depression. Second, middle school students reporting high levels of depression and low self?esteem also exhibited high levels of suicidal ideation. Moreover, for middle school students reporting high levels of depression and high self?esteem, stress revealed itself to be both a risk and protection factor when it came to suicidal ideation. Third, high school students reporting low levels of depression, recognition of low degrees of concern by their parents was a risk factor when it came to suicidal ideation. However, in the case of high school students reporting moderate levels of depression and recognition of high degrees of concern by their parents, the level of hope was predicted as both a risk and protection factor when it came to suicidal ideation. The implications of these findings and suggestions for future research are also discussed.

Study investigates the moderating effect of job esteem on the turnover intention of travel agent employees caused through jaycustomer behaviors (destruction type, linguistic and/or physical violence type and bad credit type). Through wider understanding in both of travel agents and the employees, basis materials suggesting the improvement direction in the aspect of human resource management can be provided for even better service quality which is the goal of this study. The result of the analyses is as follows: among the three sub-factors of jaycustomer behaviors the linguistic and/or physical violence influenced the turnover intention in positive (+) direction; and the destruction type and bad credit type did not influence it with statistical significance. The result of testing the second hypothesis which states that job esteem (positive value, contribution to society, relative benefit) controls the turnover intention caused through jaycustomer behavior demonstrates that the sub-factors of job esteem (positive value, contribution to society, relative benefit) are not influential; however, each factor influenced it independently. It means that the higher the job esteem(positive value, contribution to society, relative benefit), the lower turnover intention; however, as a result, it is identified that job esteem(positive value, contribution to society, relative benefit) could not control the turnover intention caused by jaycustomer behaviors.

위기 대응시 쟁점의 간극(Gap)과 속도(Tempo)가 위기 커뮤니케이션 수용에 미치는 영향에 관한 연구 : 군의 비행체 사고를 중심으로

나승용(Na, Sengyong),마정미(Ma, Jung Mi) 한국광고홍보학회 2021 광고연구 Vol.- No.130

조직에 위기가 발생했을 때 조직은 위기 커뮤니케이션 과정을 거쳐 위기를 관리해 나가고자 노력한다. 그러나 조직의 위기 대응에도 불구하고 언론을 포함한 일반 공중의 반응은 조직의 위기관리 노력에 상응한 결과를 가져오지는 않는다. 이 연구는 위기 대응시 가장 크게 영향을 미치는 요소는 무엇인지를 찾아보고 이를 기초로 위기관리 모델을 모색해보는 데 있다. 이를 위해 군에서 발생한 비행체 사고 4건을 분석하고 연구자가 제시하고자 하는 위기관리 모델에 대입하여 모델의 타당성 여부를 확인하였다. 연구자는 위기 대응에 가장 크게 미치는 요소를 ‘쟁점의 간극(Gap)과 속도(Tempo)’라고 봤다. 위기는 ‘관계에 기초한 인식의 문제’라 할 수 있고 모든 전략의 한 축은 ‘시간’일 수밖에 없기 때문이다. 이런 면에서 쟁점에 대한 갈등의 간극(Gap)과 시간의 속도(Tempo) 요소에 기초하여 위기 커뮤니케이션 전략의 모델제시 가능성을 살펴보고자 했다. 보다 구체적으로는 쟁점의 간극(Gap)은 충돌(Discord)과 합의(Accord)라는 하위 변인으로 나뉘고 속도(Tempo)는 적시성(Timing)과 지속성(Continuity)으로 나눴으며 이들 변인들이 4개의 셀을 만들어 내는 일명 DATC Matrix가 만들어졌다. 이후 간극(Gap)과 속도(Tempo)가 공중의 조직에 대한 평가를 함에 있어서 얼마 정도의 효과를 가질 것인가 여부를 확인하였는데 여기서 공중이 조직에 대해 갖는 평가에 대한 정도는 비행체 사고 및 이를 처리해 나가는 과정에 있어 언론보도 기사 제목과 공중들이 나타내는 댓글을 감성분석하고 그 결과치를 지표로 삼았다. 연구 결과 DT 전략에서는 논란 쟁점에 대해 쟁점별 집중화된 노력을, AT 전략에서는 관심 쟁점에 대해 pin-point식 관리 노력을, DC 전략에서는 핵심 쟁점에 대해 계산된 모험에 의한 관리 노력을, AC 전략에서는 잠재 쟁점을 발굴하여 사전 차단하는 노력을 기울여 나가는 것이 타당하다고 판단되었다. 이외에도 환심사기전략을 구사하고 있는 조직(해군·공군)이 환심사기 전략을 구사하지 않는 조직(육군·해병대)에 비해 조직에 대한 신뢰도를 더 높게 가지는 것을 확인해 볼 수 있었다. Crisis can be said to be ‘a problem of perception based on relations’, and one axis of all strategies is considered to be ‘time’. In this respect, I tried to examine the possibility of presenting a model of a crisis communication strategy based on the GAP of the conflict on the issue and the TEMPO element of time. More specifically, the GAP of the issue is divided into sub-variables called Discord and Accord, and TEMPO is divided into Timing and Continuity. Each cell name was named after the acronym, as DT strategy, AT strategy, DC strategy, and AC strategy, and a so-called DATC Matrix was created in which these variables create four cells. After that, it was confirmed how much effect GAP and TEMPO would have in evaluating public organizations. And it was checked whether or not it could have any effect in carrying out these strategies. As a result of the study, it was judged that it is reasonable to focus on the controversial issues in the DT strategy, focusing on each issue. In the AT strategy, it is reasonable to make an effort to manage only the issues of interest in a pin-point manner. In a DC strategy, it makes sense to manage key issues by calculated risk. In the AC strategy, it is considered reasonable to make efforts to identify potential issues and block them in advance. In addition, it can be seen that organizations that use the ingratiation strategy (Navy/Air Force) have a higher degree of trust in the organization than those that do not use the ingratiation strategy strategy (Army/Marine Corps).

NaF(sodium fluoride)용기를 이용한 Glucose와 HbA1c의 성적에 관한 비교분석

정안나 ( An Na Jung ),최정미 ( Jung Mi Choi ),최삼규 ( Sam Kyu Choi ),조영숙 ( Young Sook Cho ),박정오 ( Jung Oh Park ) 대한임상검사과학회 2003 대한임상검사과학회지(KJCLS) Vol.35 No.1

The blood glucose and hemoglobin A1c (HbA1c) tests play important roles in many diabetes research projects, including the Diabetes Control and Complications Trial (DCCT). This study was conducted to research the effectiveness of conducting HbA1c tests with NaF containers that have been used for blood glucose testing in diabetes screening. We performed glucose tests (HA7170, Hexokinase method) and HbA1cs (Variant II, HPLC method) with 150 patient subjects. The correlation coefficients value(r) was 0.9943 (P<0.01, y=0.9967x+0.0275) for HbA1c tests using the EDTA and NaF containers. Compared with glucose concentrations, mean HbA1c concentrations were 70-110 mg/dL 5.21±0.52%, 110-200 mg/dL 5.36±0.88%, and 200-400 mg/dL 9.71±3.22% with the correlation coefficients value(r)=0.6381(P<0.01, y=0.0227x+ 2.9434). These results suggest that performing blood glucose and HbA1c tests with NaF containers at the same time is a possibility. In the abnormal range of blood glucose test levels(110 mg/dL > blood glucose>200 mg/dL), the rate of accordance with HbA1c readings is greater than 95%. In the range of normal blood glucose test levels(110 mg/dL < blood glucose < 200 mg/dL), occurrences where there are high blood glucose readings and normal HbA1c readings is greater than 50%. In general, HbA1c values have been referred to in monitoring MBG (Mean Blood Glucose), but for more precise data, it is important that both tests be conducted together. Furthermore, HbA1c testing is more useful than blood glucose testing because HbA1c determines MBG concentrations that are less affected by time variations than blood glucose test results.
