연구의 목적 : 연구의 목적은 축약형 월경 전기 평가서(Shortened Premenstrual Assessment Form: SPAF)의 신뢰도 및 타당도를 알아보고, 인터넷상에서의 적용 가능성을 알아보기 위하여 시행되었다. 방 법 : 월경전 불쾌장애 환자 28명과 월경 전 불쾌장애에 해당하지 않는 가임 연령의 여자 연구 대상자 27명을 대상으로 세브란스 여성 정신 건강 특수 클리닉 홈페이지를 통하여 축약형 월경전기평가를 시행하게끔 하였다. 월경전 불쾌장애의 진단은 2개월간의 전향적인 평가를 통해 내려졌다. 결 과 : 축약형 월경전기 평가서는 정동요인, 통증 요인, 수분 저류 요인으로 구성되어 있으며, 검사-재검사 신뢰도는 0.80으로 우수하였다. 내적 일치도(Cronbach alpha) 또한 0.91로 우수하였으며, 월경전기평가서 점수와 축약형 월경전기 평가서의 상관계수는 0.92로 나타났다. 월경 전 불쾌장애 환자군과 월경전 불쾌장애에 해당하지 않는 연구 대상군 사이의 축약형 월경정기평가서 점수도 유의한 차이가 있었고(t=5.57, p<0.001), 판별 분석상에서 축약형 월경전기 평가서 점수가 두 집단을 잘 판별할 수 있는 것으로 나타났다(eigenvalue : 0.60, canonical correlation coefficiency : 0.61, Wilk's lamnda : 0.63). 두 집단을 구분하는 최적 절단점은 27점으로 추정되었고, 이때의 민감도(75%)와 특이도 76.9%)는 비교적 우수한 것으로 나타났다. 결 론 : 이상의 결과들을 종합할 때, 축약형 월경전기 평가서는 신뢰도 및 타당도가 우수한 월경전기증상 평가 도구로서 인터넷상에서도 유용하게 사용될 수 있는 도구임이 시사된다. Objectives : The purposes of this study are to investigate the reliability and validity of shortened premenstrual assessment form and the applicability to internet interface. Method : The total of 55 subjects were included in this study. Among them, 28 subjects had premenstrual dysphoric disorder, and the other 27 subjects did not. All subjects performed the shortened premenstrual assessment form through internet interface in the homepage of Severance Woman Clinic. The diagnosis of premenstrual dysphoric disorder was determined by prospective assessment for 2 months. Results : The shortened premenstrual assessment form consists of 3 factors : affect, pain and water retention. The test-retest reliability of this scale was 0.80, and internal consistency(Cronbach alpha) was 0.91. The correlation coeffeciecy between scores of the premenstrual assessment form and the shortened premenstrual assessment form was 0.92. The difference of the scores of the shortened premenstrual assessment form between the group of premenstrual dysphoric disorder and the group of non-premenstrual dysphoric disorder was significant(t=5.57, p<0.001). Discriminant analysis also revealed that the shortened premenstrual assessment form was useful to differentiate between premenstrual dysphoric disorder and non-premenstrual dysphoric disorder(eigenvalue : 0.60, canonical correlation coefficiency : 0.61, Wilk's lambda : 0.63). The cut-off point to differentiate between two groups was 27, and sensitivity(75.0%) and specificity(76.9%) of this scale for premenstrual dysphoric disorder was acceptable. Conclusion : In summary, the shortened premenstrual assessment form appeared to be reliable and valid for the assesment of premenstrual dysphoric disorder. And the results of this study also suggest that the shortened premenstrual assessment form is a useful tool for internet interface application.

As early as 1889, treatment of ostemyelitis was reported using xenogeneic demineralized bone. In 1965, Urist discovered that demineralized long bone fragment, even when implanted in nonskeletal tissue, would stimulate osteogenesis. The clinical use of demineralized bone of Oral and Maxillofacial surgery is not new. The demineralized bone implants were used for 1) interposition within osteotomy gaps, cystic detects, alveolar clefts ; 2) augmentation, over intact bone surfaces ; 3) construction of new bone within soft tissue. Demineralized bone grafts invokes a induced osteogenesis which is transformation of host cells into osteoblasts. Demineralized bone has identified several factors that modulate the osteogeneic response : sterilization method, recipient age, particle size etc. Especially, pulverization of bone matrix may enhance its osteoinductive properties, to allow rapid, efficient bridging of large defects. the purpose of the present report was to describe the potential efficacy of demineralized allogeneic bone powder of skull of rabbits as a particle size ; 212 ㎛, 710㎛, 1 mm each other. Microscopic finding in our experimental studies shown that 710㎛ demineralized bone powder is the most potent osteogenic response, and then 212㎛, 1mm size. Densitometric analysis shown that density of all group was continue to increase until 4 weeks after operation, and then continue to decrease.

The traditional control chart for treating certain kinds of quality control data assumes the existence of normerlity and independence in the data. When either independence and/or normality are present, as is usually the case, application of the traditional control chart introduces large errors in the analysis of the data and renders conclusiona based on them dubious. This paper modifies and extends the traditional control chart by utilizing the time series analysis approach and by introducing dependence via a first-order autoregressive process(AR(1) Model). We show that the modified EWMA control chart be excuted well in presence fo data correlation.

연구목적 : 월경전기 증후군의 원인에 관한 많은 가설 중에 여러 인지모델이 제시되어왔다. 즉, 부정적인 인지적 특징을 가진 사람이 월경전기 증상을 더 심하게 겪을 수 있다는 것이다. 본 연구의 목적은 월경전기 증상을 가진 여성에서 인지적 양식 및 스트레스 지각과 월경전기 증상과의 관계를 알아보고자 시행하였다. 방 법 : 18세 이상의 가임기 성인 여성 86명을 대상으로 하여 월경전기 평가서, 역기능적 태도 척도, 자동적 사고척도-부정형, 자동적 사고척도-긍정형, 스트레스 지각 척도를 작성하게 하였다. 이 중 21명은 2개월간의 전향적인 평가를 통해 월경전 불쾌기분장애로 진단하였다. 각 변수들간의 관계는 Pearson 상관계수를 구하여 검증하였다. 결 과 : 월경전불쾌기분 장애군에서 자동적 사고-부정형(r-.65, p<.01)과 스트레스 지각(r=.52)이 월경전기 증상과 유의미한 상관이 있는 것으로 나타났다. 월경전 불쾌기분장애에 해당하지 않는 대상군에서는 자동적 사고-부정형(r=.36, p<.01)이 월경전기 증상과 유의미한 상관이 있었다. 결 론 : 월경전기 증상은 비적응적인 부정적 인지 요소와 유의한 상관 관계를 보였고, 이러한 경향은 특히 월경전 불쾌기분장애 환자들에서 보다 두드러지게 관찰되었다. 이와 같은 결과는 월경전기 증후군 및 월경전 불쾌기분장애에 인지적 요소가 영향을 미침을 시사한다. 또한, 이들 질환의 치료에 있어 인지행동치료가 효과적일 수 있음을 제시한다. Objectives : The cognitive model has been suggested to explain the pathogenesis of premenstrual syndrome. In this model, it is suggested that negative cognitive style may contribute to the experience of severe premenstrual symptoms. We conducted this study to examine the relationship among cognitive style, perceived stress, and premenstrual symptoms. Method : Eighty six reproductive aged women older than 18 years were included in this study, to complete the Premenstrual Assessment form, Korean version of automatic thoughts Ques-tionnaire-Positive, Korean version of Automatic Thoughts Questionnaire-Negative, Korean version of Dysfunctional Attitude Scale, Perceived Stress Questionnaire. Among the subjects, twenty one were diagnosed to have a premenstrual dysphoric disorder which was determined by prospective assessment for two months. The relationships among the variables were analyzed by examining Pearson correlation coefficiency. Results : In the subjects without premenstrual dysphoric disorder, there exist significant correlation between the premenstrual symptom and the score of Korean-version of automatic thoughts Questionnaire-Negative(r=.36, p<.01). In the subjects with premenstrual dysphoric disorder, premenstrual symptoms had significant correlation to automatic thoughts Questionnaire-Negative(r=.65, p<.01) and Perceived Stress Questionnaire(r=.52, p<0.01). Conclusion : Our findings show the significant relationship between negative cognitive style and premenstrual symptoms. This relationship was more prominent in the subjects with premenstrual dysphoric disorder compared to ones without it. Our findings suggest that cognitive style and stress perception may influence on the severity of symptoms of premenstrual syndrome or premenstrual dysphoric disorder, and that cognitive behavior therapy is a possible effective therapeutic strategy for those with severe premenstrual symptoms.

An empirical evidence is reported to suggest that information processing capacity (or attentional capacity) is an important index which can be utilized in the prediction of sport success. On the assumption that a simultaneous (or continuous) processing of a barrage of diverse information is a necessary condition of critical importance for success especially in team sports, it was hypothesized that mire information can be efficiently processed as the number of practice trials increases. Twenty right-handed female university students were tested under probe reaction condition with pursuit rotor task as the primary experimental task. Subjects were required to respond as quickly as possible to auditory signals inserted during the performance of the primary task. Using one-way ANOVA with repeated-measures, analyses of the number of contacts with the target on the pursuit rotor as well as of probe reaction times to the auditory stimuli revealed that: 1) the performance scores on the pursuit rotor increased proportionally as a function of the number of practice trials ans 2) the probe reaction time, in contrast, decreased significantly as practice continued. These results were interpreted to strongly suggest that information processing capacity as evidenced by significant decrease in probe reaction times as a function of practice trials is inti mately related to the efficiency of task performance and, thus, may well serve as an important predictor of sport success, especially in sports where a simultaneous (or parallel) processing of a large amount of information is necessary.

The number of summary KRs was systematically manipulated in a 4×6 factorial design(Condition×Block) with repeated-measures on Block in order to test the guidance hypothesis. According to the guidance hypothesis, it was expected that the degree of the skill learning effect might be inversely related to the number of KRs summarized in the practice trials. That is, too much information given through increasing the number of summary KRs may cause dependency-producting effect on the learner, thus degrading learning. The analyses of data were in negation of the guidance hypothesis. Learning effect as evidened in the comparison of retention tests was largest when the number of summary KRs increased, while no significant performance differences were evident among groups.
