This study investigates the effect of group size on group performance, here the quality of group decision, Four effects are proposed and tested in a field experimental setting : (1) the relationship between the group size and the distribution of individual's problem-solving ability ; (2) the change of the group decision quality as group size increases ; (3) the relationship between the group decision quality and the quality of the best/worst member as group size increases ; (4) the relationship between the group decision quality and the average quality of individuals in the group as group size increases. Data showed that contrary to the exiting results, group decision quality was not improved with the group size. Rather, it showed a little tendency that group decision quality was worsened with the group size. Data also showed that consensus-oriented group decision making process produced the compromised output. Thus, group decision quality was not better than the average group members'. The opinion of the best member was not accepted. The implications of the findings are discussed for the development of a Korean GSS.

Purpose: The purpose of this study is to objectively and systematically investigate the effect of Kinesio taping by organizing and analyzing the research results using effect size. Methods: A total of 1,000 papers was searched, and 100 of them were selected the first time. Afterward, the effects of taping were analyzed and classified papers that studied balance, muscle strength, and pain, and finally 34 papers were selected. The effect size was calculated using the Effect Size Calculators (University of Colorado, USA) program. Statistical analysis was performed by using PASW Statistics software version 23.0 (IBM Co., Armonk, NY, USA). Descriptive statistics were used to obtain the effect size and confidence interval for each group. Results: In a study related to balance control ability, the effect size was 1.519 in the young subjects group (20-39 years old), and the effect size in the elderly group (65 years or older) was 0.360. In a study related to muscle strength, the effect size was 0.469 in the group of young subjects and 0.250 in the middle-aged group (40-65 years old), and the effect size of the elderly group was 0.848. In the study related to pain control, the effect size was 0.469 in the young group, the effect size of the middle-aged group was 0.972, and the effect size of the elderly group was 1.040. Conclusion: Kinesio taping differed in the degree of effect according to the age group of the subjects, but it was effective in balance control ability, muscle strength, and pain.

It has been generally believed that the impaction or eruption of mandibular third molars has significant correlations with the growth of the mandible, size of mandibular arch and size of teeth. The purpose of this study was to examine if there is any correlation between the status of eruption of mandibular third molars and the amount of mandibular crowding. The effect of missing of third moalrs to mandibular crowding was studied as well. 140 adult students of Yonsei University were selected and divided into three groups according to the status of mandibular third molars, Group 1) congenital missing group, Group 2) eruption group, and Group 3) impaction group. The tooth size, dimensions of the mandibular dental arch, and the amount of crowding were measured and compared. Results were as follows ; 1. There was no statistically significant difference in tooth size between the missing group and the eruption group(p<0.05). Impaction group showed larger total tooth material, inci- sal tooth material, and individual tooth size except central incisors compared to missing group (p<0.05). Impaction group showed larger total tooth material, incisal tooth material compared to eruption group as well(p<0.05). When individual tooth size was compared, impaction group had larger central incisors, canines, and second premolars than eruption group(p<0.05). 2. Missing group showed larger intermolar width than impaction group and it was stati- stically significant(p<0.05). 3. When compared the amount of total crowding, impaction group showed the largest am- ount of crowding, then eruption group, and missing group showed the least amount of crowding respectively(p<0.05). There was no statistically significant difference between missing stoup and eruption group in the amount of incisal crowding(p<0.05). Impaction group show- ed the largest amount of incisal crowding among all three groups(p<0.05).

To study the body trunk form which is essential to clothing constructions, necessary body sizes were measured indirect1y from 216 unmarried women from 19 to 24 years old by a photographic network method. The results are obtained as follow; 1) In this study of body type measurements, the four factors of bust, abdomen, column and hip size have been divided into four-stage intervals and given the body type codes 1, 2, 3 and 4, with 1 designating the size difference of the factor with the minimum size difference of the factor with the maximum size difference from waist size. These body type codes can be easily, linguistically interpreted. In this study, among $4^4=256$ possible body types, 54 types appeared frequently. These 54 types are integrated into 6 groups of types by clustering analysis. Representative types of each group are types 3333 and 2333 in group 1, 2233, 1233 and 1332 in group 2, 2222, 1222 and 1223 in group 3, 2223 in group 4, 2323 and 2322 in group 5, and 3323, 3223 and 3322 in group 6. In the types of groups 1, 2, and 3, the change is mainly in bust size, and in the types of group 4. is single type. In the types of group 5 the change is mainly in hip size, and in the types by groups 6 the change is mainly in abdomen size and hip size. 2) The analysis by measuring the four elements of body trunk in reference to waist size is scientific and grading of similar styles is possible in clothing construction. 3) Assuming that the human body is oval, using the calculating method, the size of girth, which cannot be measured by the indirect measuring method, is obtained approximate to actual size, with an error of ${\pm}2.8cm$.

뉴미디어는 사회적 교류의 장을 인터넷으로 옮겨와 대규모 집단이 시공간의 한계를 뛰어넘어 한 곳에서 소통할 수 있게 만들었다. 최근 연구는 인간의 사회적 능력이 소셜 미디어를 통해 경험하는 확장된 집단 스케일을 따라가지 못하는 사례를 보고하기도 한다. 이러한 맥락에서, 본 연구는 인간의 사회적 정보 지각이 인구 집단 스케일의 확장에 영향을 받는지 다수편향 맥락에서 확인하였다. 인터넷 기반 과제를 통해 구성원의 수로 나타낸 집단 크기와 전체에서 특정 집단이 차지하는 집단 비율이 개인에게 지각되고 다수편향적 사회적 정보 활용에 영향을 주는 심리적 과정을 조사하였으며, 전체 집단 스케일의 확장에 각 과정이 영향을 받는지 살펴보았다. 집단 비율은 다수편향에 정적 영향을 주고 있으며, 그 관계는 비율 지각에 의해 부분매개 되었다. 전체 집단 스케일은 집단 비율과 비율 지각의 관계를 조절하지 않았다. 반면, 집단 크기와 다수편향의 상관은 유의하지 않았다. 전체 집단 스케일은 집단 크기 지각을 조절하였다. 전체 집단 스케일이 작은 조건에서 집단 크기와 크기 지각은 양적 상관을 나타냈지만, 전체 집단의 스케일이 확장된 조건에서 지각된 집단 크기는 유의미하게 작아졌고, 두 변수는 상관을 잃었다. 이러한 결과를 통해 집단 크기 지각과 관련된 심리 기제가 전체 집단 스케일의 확장에 제대로 반응하지 못하고 있음을 확인하였다. 나아가 집단 크기 정보를 처리하는 전문화된 심리 기제가 존재할 가능성과 다수편향이 특이적으로 받아들이는 자극의 형태를 진화심리적 관점에서 논하였다.

The purpose of this study is to analyze the sizing system and size designation of ready-made jackets for women. We survey the sizing system and size labeling that have been used and presently practiced by the domestic garment industry of ready-made woman's jacket. In addition, 264 tailored jackets are measured for the sake of this study. The jackets are classified into 3 groups(young, missy, and madame) according to the target age of the brand. The result shows that size labeling involves body measurements(85-94-160), size code(55, 66) or simplified letter(S, M, L). However, the correspondence of size information and ease tolerances of jackets is not consistent and each company has its own sizing system. There are significant differences among young, missy, and madame group on the bust girth of apparel in 66size code. The average apparel size piteh measurement distributions(bust girth and hip girth respectively) of young group are 9cm and 13cm in 55 size code, those of missy group are 7 em and 3 cm in 66 size code, and those of madame group are 6cm and 4cm in 77 size code. The ease of bust girth and hip girth in missy group are much more than other groups.

The purpose of this study was to provide a brassiere size chart for making the well-fitted brassiere. The subjects are 2811 women whose range of age is 12 to 59. These woman were classified into 5 age groups by seniority ; age group 1(12~19), age group 2(20~29), age group 3(30~39), age group 4(40~49), age group 5(50~59). statistical differences of measurements were analyzed among 5 age groups through ANOVA. Correlation between measurements were analyzed by correlation analysis. In addition, new brassiere size chart and production rate tables were proposed in this study. The results of the study were as follows. 1) Most of the body measurements were significantly different among 5 age groups. The height was decreasing by getting older while weight was increasing significantly. The 3 girth measurements(top bust, bust, under bust girth) in breast, bust width, bust depth were apt to increase definitely. The 3 girth measurements had high Correlation coefficients among 3 girth mesurements. Therefore, it is valid to pick out cup size and under bust girth for representative items of size chart. 2) Under bust girth and cup size were chosen as 2 axes of brassiere size chart. From the dual distribution table whose intervals had been determined by KS size chart, 17 sizes, which had more than 2% of appearance, were suggested for brassiere size chart. Through these new size charts, the suggested brassiere sizes covered 82.5% of all subjects. The suggested brassiere size chart would be more helpful than KS size chart in making the well-fitted brassiere.

This study was undertaken to examine the extent to which tooth size and jaw size each contribute to dental crowding. Two groups of dental casts were selected on the basis of dental crowding. One group, consisting of 94 pairs of dental casts (46 males and 48 females) with normal occlusion. A second group, consisting of 84 pairs of dental casts (98 males and 46 females) with crowding. The results were as follows. 1. Means and standard deviations of the two groups were used to compare the two groups. 2. Significant differences were observed between two groups on the basis of tooth size, arch dimension and arch perimeter. 3. Between noncrowded group and crowded group, was crowded group was found to have large troth size than noncrowded group, while smaller arch dimension and perimeter. 4. Significant differences were observed between males and females on the basis of tooth size, arch dimension and arch perimeter. 5. Author found ideal arch shape of normal occlusion.

This study aims to compare the differences between 'consonant inventory size' and 'phonological variability' in order to examine the phonological development and characteristics of the late-talkers and typically developing expressive language agematched children and to consider the correlations between them. The study participants included fifteen late-talkers and fifteen typically developing expressive language age-matched children(TED group). The results are as follows. First, as regards consonant inventory size, there was a significant difference between late-talkers and TED group. The late-talkers' consonant inventory size was less than TED group. Second, as regards phonological variability, there was a significant difference between late-talkers and TED group. The late-talkers' phonological variability was higher than TED group. Third, in the case of late-talkers, there was no significant correlation between consonant inventory size and phonological variability; however in the case of TED group, there was a significant negative correlation between consonant inventory size and phonological variability. Therefore, phonological ability should be considered in evaluation and intervention of late-talkers.
