같은 급의 부정교합이라도 악골의 수직 수평관계, 악골과 치아의 크기에 따라서 여러 유형으로 분류된다. 여러 유형에 따라 치료방법에도 일률적일 수 없고 다양하게 된다. 진단과 치료계획 수립 시에 종종 어려움을 겪게 되는 경우가 있다. 진단의 어려움을 겪는 경우는 발치할 것인지 여부, 어떤 치아를 발치할 것인지, 악궁과 치아크기의 부조화를 어떻게 해소시킬 것인지 들의 결정을 내릴 때이다. 이런 경우 정확한 두부방사선분석 석고모형 분석, 성장과 발육분석에 의하여 판단하며 무엇보다 술자의 능력에 맞게 최선의 방법을 선택하는 것이 중요하다. 부정교합의 유형에 따라 다양한 발치 등 방법을 보고하고자 한다.

Type classification is a very needed step in recognizing huge character set language such as korean characters. Since most previous researches are based on the composition rule of Korean characters, it has been difficult to correctly classify composite vowel characters and problem space was not divided equally for the lack of classification of last consonant which is relatively bigger than other graphemes. In this paper, I Propose a new type classification method in which horizontal vowel is extracted before vortical vowel and last consonants are further classified into one of five small groups based on horizontal projection profile. The new method uses 19 character types which is more stable than previous 6 types or 15 types. Through experiments on 1.000 frequently used character sets and 30.614 characters scanned from several magazines, I showed that the proposed method is more useful classifying Korean characters of huge set.

The purpose of this study was to synthesize the effects of the information literacy instruction using meta-analysis. Results using random-effect models were as follows. First, the overall average effect size (ES) of information literacy instruction (Hedges'g) was 0.72, which could be interpreted based on Cohen's guidelines as moderate to large. Second, the two types of information literacy instruction, demonstrating more than medium ESs, did not show significant differences in their ESs. Third, the ESs of information literacy instruction differed depending on the measuring variables. Fourth, grade, study design and the form of the measurement tool were moderator variables that explain the differences in ESs. In sum, the effects of information literacy instruction, having more than medium effect size, seem quite stable across instruction types and study designs.

The purpose of this study is to verify the learning effect of domestic flipped learning in meta - analysis. We collected a total of 95 studies on flipped learning effectiveness published in Korea by 2017, of which 59 are dissertations and thesis and 36 are academic papers. The results were analyzed using CMA program. First, the learning effect of flipped learning was .58, which showed that the learning effect was higher than the lecture class. Second, the effect size of cognitive, affirmative, and interpersonal domains showed significant effects of flipped learning in all three domains. Third, the learning effect of flipped learning is influenced by the type of publishing, school type, core subject, when the type of publication are dissertation and thesis, when the type of school is high school. Based on the results, this study suggested implications for the design and implementation of flipped learning in Korea.

본 논문은 선행 연구된 인공감정 모델에 성격 유형별로 정서적 특징을 반영한 캐릭터의 인공감정을 설계하여 적용하는 것을 목적으로 한다. 캐릭터의 인공감정은 성격 유형별로 정서적 특징을 생성에서 소멸까지의 시간과 크기로 표현할 수 있다. 따라서 정서의 유지시간, 정서적 경험을 한번 했을 때 느낄 수 있는 최대 크기와 정서를 표현하는 시점을 두 단계로 나누어 정서적 특성을 MBTI 성격 유형에 따라 적용한다. 이렇게 설계된 인공감정은 실제 캐릭터의 적용해보고 성격 유형에 따라 감정 표현과 변화를 분석한다.

본 연구는 주거소비규범에서의 이탈과 관계된 변수들을 조사하고자 시도되었으며, 이러한 목적을 달성하기 위한 구체적인 연구과제는 다음과 같다. 1. 미국의 각기 다른 가구유형별(가족생활주기 측면에서 구성된) 주거소비규범이 존재하는가\ulcorner 2. 규범보다 높은수준의 주거소비와 관계된 변수는 무엇인가\ulcorner 규범보다 낮은 수준의 주거소비와 관계된 변수는 무엇인가\ulcorner 자료는 미국엣 실시된 1990년도 소비자지출 조사의 인터뷰대상에서 추출된 4,923개의 소비자단위로 연구과제를 해결하기 위해 ordinary least squares(OLS) 중회귀분석방법이 사용되었으며, 본 연구에서 주거소비규범은 다음과 같은 4가지 주거특성, 즉 방수, 주거유형, 침실당 사람수 및 주거소유유형으로 확인되었다. 분석결과, 가구유형 및 크기가 규범이 존재한다고 믿어지는 4가지 주거특성과 유의하게 관련되어 있었으며, 이는 이러한 특성에 대해 규범이 존재한다는 결론을 지지했다. 한편, 다른 많은 가구들이 그들의 가구유형규범과 크기규범에 일치하지 않는 주거에서 살고 있는 것으로 나타났는데, 이러한 이탈은 소득, 가장의 연령 및 성별과 같이 자원제약을 나타내는 변수와 관계되어 있었다. 본 연구의 결과는 왜 인구통계적 변수가 주거 및 다른 소비와 관계 되는지에 대한 이유를 설명할 수 있도록 하는 근거를 제시하고 있으며, 주거소비만족과 주거조정행동의 근거를 이해하는데 적용될 수 있을 것이다.

본 논문에서는 CCD카메라로 입력 받은 다중 크기 및 활자체로 구성된 한글문서의 화상 데이터를 편집기에서 수정 가능한 문자로 변환시키는 시스템을 구현하였다. 먼저 Dynamic 이 진화 처리 과정을 거친 화상을 흑백 화소의 누적분포에 따라 문자단위로 분할한 후, 다양한 크기로 분할된 문자를 표준패턴 크기로 표준화 시켰다. 한글을 자소 간 공백 위치의 특징에 따라서 6가지 유형으로 분류한 후, 퍼지 이론을 접목시킨 원형 패턴 벡터 알고리즘을 사용해서 표준벡터와 입력된 글자의 특징벡터를 비교하여 문자로 인식하게 하였다. 각 6가지 유형에서 서로 다른 자소로 결합된 문자들을 30개 선정하여 여러 가지 활자체 및 크기에 적용해 본 결과, 모두 문서화가 가능함을 알 수 있었다.

The purpose of this research was to present the basic data for developing meditation programs by verifying the effect size using meta-analysis of the results from previous studies on meditation program of the elderly. In order to analyze the effect sizes of program types, group of mediating variables and activity factors of elderly meditation programs, this study reviewed 24 precedent research that have been conducted from 2003 through April 2017 in Korea using meta-analysis and summarized the effect sizes are as follows. First, the overall average effect size was .914, which was great. Among the program types, complex meditation was 1.726, which was the greatest. Among the group of mediating variables, the positive psychological variable group had the highest in 1.368 and the gender consists only of women had the highest in .921. Secondly, concerning the activity factors, when the total number of sessions was 12~20 times(1.193), sessions per week was twice(1.254), time went for 110~120 minutes per session(1.581) and the group size was 71~100 persons(1.535) that were shown as higher effect size. Among the types of publications, articles in journals(1.062) had a higher effect size than dissertations(.817). For the organizing elderly meditation program in the future, I suggest that the program type of complex meditation, 12~20 time of total sessions, twice a week, 110~120 minutes of activity hours. At the time we entered the aged society, this study is meaningful in that it provides the basic data for future program development by confirming the effect size according to program types, mediation variables and activity factors for the meditation program performed for the elderly.

Size>; and sculpture pattern of pollen grains in seven species and two varieties of the genus Lilium in Korea were examined by LM and SEM, and their evolutionary trends were discussed. Lilium species in Korea can be divided into two groups based on pollen morphology: one is small reticulate group with small pollen grains and lumens, which includes L. concolor var. pulchellum and L. callosum; the other is large reticulate group with large pollen grains and lumens, which includes remaining taxa. It is thought that small reticulate group is more primitive than large reticulate group on the basis of tectum coverage. According to the above results and some morphological characters of salles and perianth segments, L. concolor var. pulchellum and L. callosum are very closely related, and they would be treated under the same subsection.ection.
