본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).

This study is an exploratory study to identify Enneagram personality types. It aims to develop barometers for Ennegram personality type cards and to verify how those barometers reflect the Enneagram personality types. In this study, question items that serve as barometers for Enneagram personality type cards were sampled and selected through the first, second and third processes. During the first question selection process, question items was sampled through literature search and workshops for adults, and then a total of 114 questions per Enneagram personality type were sampled based on experts' validation. In the second process, the 114 questions sampled in the first process were validated by 5 Enneagram experts to select 77 questions. In the third process, the selected 77 questions were used to analyze the data from 168 females and male adults living in the Gyeongin area, and then questions whose correlation coefficient is 0.30 or higher were selected per personality type. A total of 69 questions were finally taken as the confirmed set of barometers. The meanings of the result of this study are as follows; First, this study selected questions based on four elements of personal types such as strength, weakness, stress pointer and stability pointer. Second, in order to understand the Enneagram personality types, this study broke away from the existing quantitative approach while using the advantage of personality type cards that take a qualitative approach, which enables one to observe oneself more easily, flexibly, and minutely. Third, this study can provide the basic data which are mutually complementary with the existing barometers in examining the personality type of one own. Furthermore, if the barometers are supplemented through the more elaborate study designs and its execution, they could become the highly reliable and validate barometers which is very useful as personality test too.

Conformity and nonconformity in dress are the two driving forces that make diffusion of new styles. More fundamental personal attributes that affect individuality in dress are masculine or feminine sex roles. Researchers reported that little differences were found between men and women in terms of conformity values. Fashion and clothing products are related to hedonic shopping and major hedonic shopping orientations in clothing shopping behavior of college students were often reported. This study was aimed to empirically test the effect of personality traits of masculinity-femininity on nonconformity and conformity in dress; the effects of nonconformity and conformity on major hedonic shopping orientations. A survey questionnaire was developed for the empirical research. Data from 181 students were used for statistical analysis using structural equation modeling. A conceptual model with masculinity and femininity as two exogenous variables, two shopping orientations as endogenous variables and nonconformity-conformity as two mediating variables were analyzed. Results confirm the significant structural paths from masculinity to nonconformity, from femininity to conformity and from nonconformity to novelty-seeking and conformity to fashion seeking) were statistically significant. The results of this study suggested that The personality traits and shopping orientation were antecedents and consequences of nonconformity-conformity in dress and clearer relationships do exist in the flow.

저자들은 정신분열병의 일부에서는 태생기 동안 유전 외적인 환경적 요인이 크게 작용할 것이라는 가정 하에 형제 정신분열병 환자군(남 15. 여 7)과 산발성 정신분열병 환자군(남 16, 여 7) 및 정상 대조군(남 16, 여 7)을 대상으로 가족력에 따른 산과적 합병증과 신체 미세 기형을 비교하였다. 산과적 합병증은 Lewis 척도를 이용하여 연구 대상의 어머니와 면담하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 또한 산과적 합병증 및 신체 미세기형과 가족력에에 따라 발병 연령 등의 임상 양상들이 차이를 보이는지 비교함으로써 정신분열병을 좀 더 동질적인 아형으로 나눌 수 있는지를 검토하였다. 1) 형제 환자군, 산발성 환자군 및 정상 대조군의 세균에서 산과적 합병증의 개개의 항목 및 전체 점수의 유의한 차이는 없었다. 신체 미세기형의 경우 입의 미세기 형에서 유의한 차이가 있었으나 그 외에 각 부위별 점수 및 전체 점수에서는 세 군간에 유의한 차이가 없었다. 그러나 대부분의 신체 미세기형 세부 항목 및 전체점수에서 산발성 환자군이 형제 환자군에 비해 높은 신체 미세기형의 점수를 보이는 경향이 있었다. 2) 산과적 합병증의 전체 점수와 신체 미세기형의 전체 점수 사이에 상호 연관성을 찾아볼 수 없었다. 3) 발병연령·정신병리·약물에 대한 반응·병전 기능수준·지연성 운동장애 유무 등의 임상 양상들을 비교하였을때 산발성 환자군과 형제 환자군간에 유의한 차이가 없었다. 4) 산과적 합병증 및 신체 미세기형과 임상 양상들을 비교하였을 때, 형제 환자군에서 분만시간과 회복시 전반적 기능수준간에, 산발성 환자군에서 산과적 합병증의 전체 점수와 발병 연령간에 상관관계가 있었으나 전체적으로 일관된 결과가 도출되지는 못하였다. 위와 같은 결과를 종합하여 볼 때, 산과적 합병증이나 신체 미세기형이 정신분열병의 원인을 밝히는데 유익한 도구가 될 수는 있지만, 가족력 유무에 따라 정신분열병을 보다 동질적인 아형으로 구분하기 힘들다고 생각되었다. In order to test the hypothesis that familial schizophrenics have fewer chances of receiving organic insults during the fetal neural development than sporadic schizophrenics, the authors compared obstetric complications, minor physical anomalies, and other clinical features in sibling schizophrenics, sporadic schizophrenics and controls. Obstetric complications were evaluated by the scale of Lewis, and minor physical anomalies were measured by the Waldrop scale. Sporadic schizophrenics had a significantly higher Waldrop score for mouth than sibling schizophrenics. Although there was some tendency of higher total scores for minor physical anomalies in sporadic schizophrenics, there were no statistically significant differences in obstetric complications and the other minor physical anomalies among three groups. There was no significant correlation between obstetric complications and minor physical anomalies. The clinical features such as age of onset, psychopathology, response to drugs, premorbid functioning, and tardive dyskinesia were not significantly different between sibling and sporadic scizophrenics. In conclusion, while the obstetric complications and minor physical anomalies were suggested to be useful in the search for the cause of schizophrenia, it was difficult to categorize schizophrenics into more homogeneous groups according to family history of schizophrenia using the parameter of obstetric complications and/ or minor physical anomalies.
