  • In co-authorship networks, temporal networks can be modeled by identifying the formation and dissolution (linking and removing) of co-authorship relationships over time from the publication year information of the papers. Therefore, this study seeks to analyze the overall research collaboration networks of data papers and articles from an evolutionary perspective for modeling the temporal network in terms of informetrics and investigating the dynamic and structural mechanisms of the temporal co-authorship network. For that purpose, Biodiversity Data Journal, a mixed data journal in the biodiversity domain was used as the unit of analysis in this study as this domain had proposed data paper as a new mechanism for data publication. In addition, bibliometric records of 247 data papers and 638 articles involving two or more researchers were collected from the Web of Science. The results indicated that the dynamic co-authorship networks of data papers and articles in the biodiversity domain exhibited the scale-free property of a complex network and the small-world property in the Watts-Strogatz sense during the network evolution. Also, both publication types kept the structure of locally cohesive author groups over time in the networks. The implementation of TTBC (Temporal Triadic Betweenness Centrality) has allowed for the examination and tracking of the evolutionary trends of important or influential time-dependent authors (nodes) by the target year. And last, visualization with a dynamic approach enabled a more effective identification of analysis results, such as the exhibited structural difference in the temporal co-authorship networks of data papers and articles in the biodiversity domain, which can be interpreted as the structural properties of the networks among collaborative researchers dealing with data.

  • The purpose of this study was to examine the effect of group music therapy program on alineation of adolescents from enmeshed or disengaged families. The Family Adaptability and Cohesion Evaluation Scales III was administered to screen out subjects at a high school in Seoul. Based on the low scores, between 10 and 25, rated on the scale, 4 students were selected from 148 initial respondents. Subjects participated in group music therapy program for 7 weeks and a total of 14 music therapy sessions were provided for them. After the program, content analysis of the subjects' verbal and musical expressions observed during the program was conducted, with regard to the measures of the Student Alienation Scale. The results showed negative self-expression decreased while positive self-concepts increased. These results indicate that by providing the opportunity to experience group cohesiveness and group support, group music therapy program may effectively reduce alienation of adolescents from enmeshed or disengaged families.

  • Castera is a favorite food which is well known to the general public made by egg, sugar and wheat flour. This study is carried out in order to investigate to the physical properties of eastern. The results are summarized as follows: 1) As a result of the sensory evaluation for eastern with 19 kinds of material in Kyushu on the market, it could be classified into 3 types: A) high grade (Castera), C) low grade (Sponge cake), and B) midium grade (Something middle of those). 2) In the texturometer measurement for eastern, hardness of A type was highest, B and C are 22∼35% lower than A type, while cohesiveness and springiness are not significantly different. 3) In the creep test, 3 types are all the S-element Voigt model, consisting of Hookean body, Newtonian body and two sets of Voigt body. Eo of A type is 13∼36% higher than other types, it tends to the same result of hardness. The parts of retardation strain of A type are 21∼41% lower than B type, 8∼l3% higher than C type, respectively. 4) About the day change of eastern of A type, mechanical model is not changed.

  • This study was performed to examine the quality characteristics of the sponge cakes with different contents (2-10% (w/w)) of lemon grass powder (LGP). An increase in LGP content in the cake led to a significant increase in the specific gravity of batter, baking loss rate, redness, hardness, cohesiveness, chewiness, and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of the cakes and a significant decrease in pH, moisture content, specific volume, height, volume and symmetry index, lightness, and yellowness of the cakes. Springness and resilience did not show any difference between the cakes. The consumer acceptance test indicated that the addition of LGP up to 2% did not cause a significant negative effect on the consumer acceptances in all attributes. The sponge cakes with 2% LGP can be recommended for manufacturing bakery.

  • We examined the dough properties, baking qualities, and sensory aspects of commercial hard wheat flour (Q1) that was supplemented with up to 30% rice bran flour. The loaf volumes of bread with 20% and 30% rice bran were 83% and 65% respectively, of the control (wheat flour only). However, a 5% and 10% supplement of rice bran increased loaf volume by 5.2% and 0.7% respectively, over the control. After storage of loaves for three days, bread crumbs from loaves with 5% rice bran were significantly softer than those with 10% 20% and 30% rice bran. The hardness of dough increased with the proportion of rice bran, but springiness and cohesiveness were inversely related to hardness. Addition of rice bran increased loaf pH. Rice bran decreased lightness, but significantly increased redness and yellowness in a concentration dependent manner. Sensory investigation indicated that bread with 5% rice bran was not significantly different from the control. However, more panel members preferred the appearance and flavor of bread with 5% rice bran.

  • To establish a foundation to objectively interpret Chosun history, we construct people network of the Chosun dynasty. The network shows scale free network properties as if most social networks do. The people network is composed of 1,379 nodes and 3,874 links and its diameter is 14. To analysis of the network dynamics, whole network that is composed of 27 king networks were constructed by adding the first king, Taejo network to the second king, Jeongjong network and then continuously adding the next king networks. Interestingly, betweenness and closeness centralities were gradually decreased but stress centrality was drastically increased. These results indicate that information flow is gradually slowing and hub node position is more centrally oriented as growing the network. To elucidate key persons from the network, k-core and MCODE algorithms that can extract core or module structures from whole network were employed. It is a possible to obtain new insight and hidden information by analyzing network dynamics. Due to lack of the dynamic interacting data, there is a limit for network dynamic research. In spite of using concise data, this research provides us a possibility that annals of the Chosun dynasty are very useful historical data for analyzing network dynamics.

  • This study was to know the influence of familial environment and moral development on conduct disorder. Subjects were composed of 47 male and female patients with conduct disorder(patients group), 113 general male and female students(normal group), and 173 juvenile prisoners(JP group). The Korean Form of the Family Environment Scale(FES) was used to assess the family environment of the subjects and the Korean Defining Issues Test(DIT) was used to assess the moral development. Conduct disorder was diagnosed with the DSM-III-R criteria for conduct disorder. The influence of familial environment and moral development on conduct disorder was analyzed with ANOVA and the differences among groups were verified with Scheffe test. There was no difference in the socioeconomic status and the physical abuse by the parents among the three groups. But the rates of divorce or separation of the parents were significantly highest in the JP group and higher in the patients group than in the normal group. Especially the subjects of the JP group experienced the divorce or separation of their parents during the preschool or the elementary school periods. In regard to the family environment, there was no difference among the three groups in the Subscales of Expressiveness, Independence, Intellectual-cultural orientation, Moral-religious emphasis, Organization, and Control. ‘Cohesion Subscale’ was significantly higher in the normal group than in the JP group. ‘Conflict Subscale’ was significantly higher in the JP and patients groups than in the normal group. ‘Achievement orientation Subscale’ was significantly lower in the JP group than in the patients and normal groups. ‘Activerecreational orientation’ was significantly lower in the normal group than in the JP and patients groups. In gegard to the moral developmental stage, the lower moral developmental step was higher in the JP and patients groups than in the normal group. The higher steps were significantly higher in the normal group than in the JP group. There was no significant correlation between the degree of ‘Moral-religious emphasis Subscale’ and the moral development. The clinical implication and limitation of present study were listed and discussed.
