This study was conducted to develop a parent's autobiography writing program and to verify its effectiveness. The subjects were 82 college students(52 students in the experimental group and 30 students in the control group) in an university in Seoul. The research design was a nonequivalent control group pretest-posttest quasi-experimental design. The effectiveness of the program was verified by ANCOVA using the SPSS 23.0 program. Parent's autobiography consisted of prologue, childhood, adolescence, adulthood, and epilogue. Each chapter of the autobiography consisted of a part of the growth narrative describing the main events of the parents and a part of the introspection narrative describing the writter's feelings. As a result of analysis, first, the parent's autobiography writing program significantly promoted parent-child relationships. Second, parent's autobiography writing programs significantly increased parent-child attachment. Third, parent's autobiography writing programs showed a significant increase in parent-child communication. Based on the results of this study, we discussed the effect and application possibility of the parent's autobiography writing program.

오늘날 영어교육은 교과과정령에 엄연히 명시된 네 가지 기능(four skills) 즉 듣기, 말하기, 원기, 쓰기라는 정당하고도 보편 타당성 있는 명분 하에 어떻게 가르쳐 왔는가 를 반문해 보면 많은 아쉬움이 남는다. 그간 6년간의 중등과정, 심지어는 대학에서 환 두해까지 영어를 이수한 사람틀 중에는 문자를 통해서는 상당한 수준, 그것도 영어 토박이들조차 놀랄 정도의 영어를 이해하지만, 소리를 통해 들을 때는 ---말하는 것은 두말 할 것도 없고---아주 간단한 내용의 영어조차 알아듣기 힘든 경험을 한 사람이 많다는 것은 부인할 수 없는 사실이다. 그 이유는 명백하다. 즉, 문자를 대할 때는 시각적 자극의 형태가 두뇌 속에 저장된 정보---가공할 문법적 지식---와 일치하기 때문에 쉽게 이해를 할 수 있는 반면, 소리를 들을 때는 청각적 자극의 형태가 두뇌 속에 저장된 정보---극히 불완전한 발음사전, 또는 모국어의 음운체계에 의한 영어발음--- 와 차이가 있기 때문일 것이다. 그러므로 적어도 말소리를 매체로 하는 의사소통에 있어서는 영어의 본토박이 발음을 정확히, 아니면 적어도 매우 근접하게 나마 터득하여(습관화하여)두뇌에 저장하는 일이 가장 중요한 일이다. 따라서 영어교사는 모국어의 음운체계에 대한 정확하고도 상세한 지식을 토대로 하여 영어의 음운체계와 '언어학적으로 의미 있는 (linguistically significant)' 대초분석의 방법으로 발음을 지도한다면 보다 나은 학습효과를 기대할 수 있을 것이다. 일반적으로 모국어의 발음이 외국어의 발음에 간섭을 유발하는 경우는 다음과 같다. 1. 분절음체계가 서로 다를 때 2. 한 언어의 음소가 다른 언어의 이음(allophone)일 때 3. 유사한 음의 조음장소와 방법 이 다를 때 4. 분절음의 분포 또는 배열이 다를 때 5. 음운현상이 다를 때 6. 언어의 리듬이 다를 때 위의 여섯 가지 경우를 중심으로 영어와 한국어의 발음특성을 대조하여 '낯선 말투(foreign accent)' 또는 발음오류를 최소로 줄이는 것이 영어교사의 일차적인 목표이다.

Relationship between the daily mortality and total suspended particulate(TSP) for the period of 1996-1997 was examined in Seoul, Korea. Generalized additive model was adapted for the analysis to allow the seasonality and long-term time effect in the air pollution and the nonlinear relationships with weather variables such as air temperature and relative humidity. An increase of 100 Ji9/m') TSP corresponds to 0.8-5.2 percent increase of the daily mortality Unidirectional (prospective and retrospective) case-crossover design results in large bias of the estimates. Bidirectional method gives relatively unbiased estimates but the standard errors are larger Case-crossover design should be used with caution in the situation where the data have seasonal trends like air pollution study.

To elucidate the biochemical etiology. 1) plasma dopemine-beta-hydroxylase activity was measured and 2) the correlation between age and DBH activity was examined in 30 Tourette's disorder, 19 chronic motor tic disorder, and 24 controls. The results are summarized as follows : 1) The mean plasma DBH activity in Tourette's disorder was significantly elevated compared to normal groups, but significant differences in DBH activity between Tourette's disorder and chronic motor tic disorder, and between chronic motor tic disorder and normal control group were not found. 2) In all three groups, the significant positive correlations between age and plasma DBH activity found. These findings support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of Tourette's disorders, and this dysfunction might be due to the increased dopaminergic and decreased noradrenergic function. Future research should be focused on the mechanism of functional abnormalities of DBH.

Background: Osteoporosis is a significant comorbidity in patients with chronic obstructive pulmonary disease (COPD). This study examined the prevalence and risk factors associated with osteoporosis in patients with COPD. Methods: The bone mineral densities (BMDs) of the lumbar spine and femoral bone were measured in 53 patients with clinically stable COPD and 41 age- and gender-matched control subjects showing a normal lung function. Osteoporosis was defined as a T-score $\leq$-2.5. The subjects' clinical characteristics and laboratory data were reviewed, and multiple logistic regression analysis was used to identify the risk factors associated with osteoporosis in COPD patients. Results: The prevalence of osteoporosis was 47% and 32% in the COPD patients and controls, respectively. In particular, using the femoral neck T-score, the prevalence of osteoporosis in COPD patients was higher than that in the controls (26% vs. 5%; p=0.006). The average T-score of the lumbar spine (p=0.025) and femoral neck of COPD patients were significantly lower than those of the controls (p=0.001). The forced expiratory volume in the 1 second ($FEV_1$) % predicted (p=0.019; odds ratio [OR], 0.955; 95% confidence interval [CI], 0.919-0.993) and age (p=0.024; OR, 1.144; 95% CI, 1.018-1.287) were independently associated with osteoporosis in patients with COPD. Conclusion: Using the femoral neck T-score, the prevalence of osteoporosis in patients with COPD was higher than the age-and gender-matched controls. A lower $FEV_1$ and older age further increase the risk of osteoporosis in patients with COPD.

산업보건 역학의 연구결과를 우리가 어느정도로 신뢰할 수 있는지, 또는 어느정도의 정보를 제공할 수 있을지를 결정하는 요인들 중에서 중요한 것으로 간주할 수 있는 것은, 측정된 폭로자료(Exposure data)가 어느정도인지(amount), 얼마만큼 구체적이며(specificity) 그리고 얼마만큼 정확한지(precision)에 관한 것이다. 이상적으로는 우리는 각 개인개인의 폭로량을 구하고 이에 관련된 질병발생의 정도를 측정하고자 한다. 이러한 연구야말로 다른 폭로에 대하여도 일반화할 수 있는 양-반응관계를 추정하게 할 것이다. 그러나 실제로는 측정된 폭로자료를 구하기가 어렵거나 또는 아예 이러한 자료가 존재하지 않는 경우가 흔한데 왜냐하면 기술적으로 제약(특정한 물질에 대한 분석이 아직 불가능하거나)이 있거나 부족한 인적 및 물적 자원때문이다. 그러므로, 대부분의 경우에 폭로수준은 이러한 직접적인 폭로 측정자료 대신에 다른 자료로 부터 간접적으로 알아내야 한다. 이 글은 작업장 환경의 특성을 파악하는 것에 대한 개념 및 몇가지 방법 및 토의할 만한 사항을 요약한 것이다. 이들 중에서 가장 중요하게 다루게 될 사항은 아무래도 작업장에서 근로자 폭로이 강도(intensity)와 기간(duration)을 추정하는 것이 될 것이다. 이에 더하여 (예를 들어 병원환자에 대하여 환자-대조군 연구를 행하는 경우와 같이) 지역사회 연구(community studies) 또는 등록자료를 기초로 한 연구(registry-based studies)에 대한 직업적 폭로의 평가에 대하여도 간략하게 언급하도록 하겠다. - 저자 주 -

This study was carried out to investigate the collecting efficiency of cyclone deduster installed in weaned piglet building in third weeks of age. There are two peaks of high level of dust concentration in piglet house at the time of 09:00~10:00(5,322$\mu g/m^3$) and 19:00~20:00(6,763$\mu g/m^3$), but the peaks of dust concentration in the building used cyclone deduster was decreased to 3,614.8 and 2,229.5$\mu g/m^3$, respectively. Collecting efficiency of total suspended particulate(TSP), particulate matter less than 10$\mu\textrm{m}$(PM 10) and particulate matter less than 2.5$\mu\textrm{m}$(PM 2.5) in weaned piglet building used in cyclone deduster was 38.3%, 32.5, 21.8, respectively. Aerial dust in weaned piglet building by number basis in the range of 0.745~1.08$\mu\textrm{m}$ was 53.5%. But dust distribution over 10$\mu\textrm{m}$ in volume basis was 82.8% and 86.2%. Crude protein of dust was 25.9~32.7%, and it was higher than feed crude protein(22.0%). Heavy metal concentration of dust was also high level compare to that of feed.

This study investigated the acoustic characteristics of sustained vowel /a/ and sentence utterance produced by patients with muscle tension dysphonia (MTD) using cepstrum-based acoustic variables. 36 women diagnosed with MTD and the same number of women with normal voice participated in the study and the data were recorded and measured by ADSVTM. The results demonstrated that cepstral peak prominence (CPP) and CPP_F0 among all of the variables were statistically significantly lower than those of control group. When it comes to the GRBAS scale, overall severity (G) was most prominent, and roughness (R), breathiness (B), and strain (S) indices followed in order in the voice quality of MTD patients. As these characteristics increased, a statistically significant negative correlation was observed in CPP. We tried to classify MTD and control group using CPP and CPP_F0 variables. As a result of statistic modeling with a Random Forest machine learning algorithm, much higher classification accuracy (100% in training data and 83.3% in test data) was found in the sentence reading task, with CPP being proved to be playing a more crucial role in both vowel and sentence reading tasks.

The purpose of this study is to analyze the effects of the simulation-based professional cardiac resuscitation training on the performance of professional cardiac resuscitation performed by paramedics in the pre-hospital stage and to provide basic data for effective cardiac resuscitation. This study is an experimental study of the design before and after the control of non-equality. The subjects of this study were 16 newly recruited paramedics from K firefighting school. The simulation training program and evaluation papers used as the evaluation tool were reviewed and commented by 6 ACLS simulation experts (2 emergency medical doctor, 2 emergency medical professors, 2 KALS instructors)Respectively. The training consisted of 30 minutes of theory and 150 minutes of practical training. The lecturer first demonstrated for 5 minutes, and after training by individual debriefing after individual training, individual and team education was conducted The evaluation scale was given a 5 - point Likert scale. The SPSS 22.0 program for Windows was used. The general characteristics of the subjects were analyzed for frequency, the examination of homogeneity between the experimental group and the control group wasfulfilled by t test, and the difference test between the groups of the two groups was performed using the paired t-test. The homogeneity test was able to confirm the homogeneity between experimental group and control group. In the evaluation of six ACLS techniques, it was proven that the experimental group that received the simulation training had better performance in all aspects than the non - training control group. The following are the technical items to be performed. 1. Electrocardiogram 2. Specialized instrument 3. Treatment of fluid 4. Leadership and teamwork 5. Medical guidance 6. Evaluation during transfer. It was proved that paramedics who received simulation training were improved on their job performance ability than general lecture and training group. Therefore, if simulation training and education are applied to a student in the synthetic course or an emergency resident who is engaged in clinical practice, he / she will be able to perform his / her duties more proficiently. It is expected that emergency services provided to patients with cardiac arrest will be improved.

Bisphenol A (BPA) is mainly used in the production of epoxy resins and polycarbonate plastics, which is a known endocrine disruptor and acutely toxic to aquatic organisms. In this study, estrogenic effect of BPA was investigated on hybrid between Oryzias dancena and O. javanicus (ODJ). ODJ were exposed to BPA of various concentrations (eg. 2.5 mg/L, 5.0 mg/L and 10.0 mg/L) for 56 days. The growth rate, abnormality and the ratio of female and male were observed in test group and control group. As a result, the growth was $14.7{\pm}2.0$ mm in total length (TL) in 2.5 mg/L, $13.7{\pm}2.5$ mm in 5.0 mg/L, $12.8{\pm}2.5$ mm in 10.0 mg/L in test group while it was $18.0{\pm}1.2$ mm in TL in control group which was not treated with bisphenol A. The result showed that the growth decreased as the concentration of BPA increased. The abnormality rate was 13.6% in control group, 65.4% in 2.5 mg/L, 81.3% in 5.0 mg/L and 98.1 % in 10.0 mg/L which showed increase in abnormality as an increase of BPA concentration. As a result of analyzing ratio of sex in the test group and control group, 6.0% was examined to be interspecific in controls, 76.9% in 2.5 mg/L and 100.0% in 5.0 mg/L and 10.0 mg/L. In conclusion, these results suggest that BPA has estrogenic effect on ODJ.
