This study examined the mediation effect of life satisfaction between aggression and loneliness. The subjects were two hundred and eighty fifth-year elementary school and second-year middle school adolescents in Seoul. Data were analyzed by using the t-test, Pearson's correlation and regression. Major findings were as follows: First, when it comes to aggressiveness, the fifth graders showed a significantly higher degree of personal attack, whereas the eighth graders were found to show more expression of anger. The fifth graders scored higher than the eighth graders in each subcategory of life satisfaction. No significant difference was found in the category of loneliness. Second, the fifth graders showed a positive relationship among verbal attack, personal attach, expression of anger and loneliness, whereas the eighth graders showed a positive relationship between expression of anger and loneliness. The two age groups, in turn, also exhibited some differences in the relationship between loneliness and life satisfaction. Third, we found that life satisfaction is a complete parameter between aggressiveness and loneliness in the fifth graders. In the case of the eighth graders, life satisfaction turned out to be a partial parameter between aggressiveness and loneliness. This perhaps indicates that adolescents with similar levels of aggressiveness might show different degrees of loneliness, depending on whether they have positive attitudes toward their lives and whether they feel satisfied with their lives.

Objectives: This study examined the effects of middle school students emotional intelligence on their aggressiveness and interpersonal relationships. Methods: Data were collected by questionnaires from 316 middle school students in Daegu city. To analyze the sample survey data, descriptive statistics, t-test, ANOVA, pearson correlation coefficient and simple regression analysis were performed with SPSS/PC 18.0 program. Results: First, among the general characteristic differences, academic achievement and economic status yielded a significant difference in emotional intelligence. Gender, economic status, and educational background produced a significant difference in aggressiveness, while gender, academic achievement, and economic status showed a significant difference in interpersonal relationships. Second, an examination of the correlation among emotional intelligence, aggressiveness, and interpersonal relationships found that the higher the emotional intelligence, the lower the aggressive, and the higher the interpersonal relationships. Third, general characters and emotional intelligence explain 22% of agressiveness. Gender, age, economic status, and emotional intelligence have a significant influence on agressiveness. Fourth, the general characters and emontional intelligence explain 45,5% of interpersonal relationships. The economic status and emotional intelligence have a significant influence on the interpersonal relationship. Conclusion: Based on the results, the study is of great importance, in that it provides the basis for future studies, which can be used to help school teachers and students' parents understand the importance of adolescents emotional intelligence and promote the students' quality school life.

This study aimed to develop a cognitive-behavioral group counseling program for depression and aggressiveness in adolescents with delinquent propensity and to examine its efficacy through pre- and post-tests. The program included cognitive restructuring, exposure training, social skills training and relaxation training. Juvenile Delinquency Scale, BDI, K-YSR, and BDHI were administered to 520 3rd grade middle-school female students to assess their levels of delinquency, depression and aggressiveness. Initially 41 students who met all the following criteria were selected: 1) top 15% scores on Juvenile Delinquency Scale, 2) top 30% scores on BDI, K-YSR and BDHI respectively. Individuals currently receiving clinical treatment were excluded. Finally 39 students were selected and randomly assigned to either a treatment group(n=20) or a control group(n=19). Then the students in the treatment group were divided into 4 subgroups. The program consisted of 12 weekly sessions, approximately $1.5{\sim}2$ hours in duration. Pre- and post-tests administered to both groups included Juvenile Delinquency Scale, BDI, K-YSR, BDHI, and CLAB. Additionally, MESSY for teachers was added at pre- and post-tests. The collected data were statistically analyzed through independent t-test and paired t-test. The results of the study were as follows: 1) The students in the treatment group showed a significant reduction in the level of depression and aggressiveness in comparison with those in the control group. 2) Teachers reported a significant reduction in internalizing/externalizing behaviors of the students in the treatment group.

The purpose of this study was to investigate the psychosomatic health status of printers. The 77 printers and 24 control group were analysed about salary, drinking, smoking, education, sex, marriage, age and working age by the THI (Todai Health Index) questionaire. THI was modified from CMI(Cornell Medical Index) and developed by Tokyo University Research Team in Japan. The resuts obtained were summarized as follows. 1. The printers, who get more salary showed high score about mental conplaints, especially, mental irritability(j), nervusness (E), lie Scale(L), aggressiveness(F) and irregualr life(G) and lower salary showed generally high score about physical complaints, especially, mouth and anus (D), digestive symptom(C) multiple subjective symptom(I). 2. According to the printers drinking amount shows the difference, eg nondrinker scored higher on mouth and anus(D), 90mg/week drinker scored higher on multiple subjective symptom(I), digestive symptom(C), depression(K), nervousness(E), and irregular life(G), 91~179mg/week drinker scored higher on impulsiveness(H), mental irritability(J), 270~359mg/week drinker scored higher on respiratory(A), lie scale (L) and aggressiveness (F). 3. The nonsmoker scored high level on mouth and anus(D), mental irritability(J). The previous smoker scored on multiple symptom(I), eyes and skin(B), digestive(C), lie scale(L), and depression(K). The present smoker scored on respiratory(A), impulsivehess(H), aggressiveness(F), nervousness(E), and irregular life(G). 4. According to the printers working age showed almost high score about subjective symptoms on 1~3 year. 5. Men printers high scored on respiratory(A). lie scale(L), aggressiveness(F), women printers scored about mental complaints, especially, impulsiveness(H), mental irritability(J), depression (K), nervousness (E). 6. According to the printers age showed high scored about, below 20 years were lie scale(L). aggressiveness(F), irregular life(G) 21~30years were multiple subjective symptom(I) respiratory (A), eyes and skin(B), mouth and anus(D), impulsiveness(H), mental irritability(J), depression (K), nervousness(E), and over 41 years were digestive(C). 7. Married printers scored high level on eyes and skin(B), digestive(C) and impulsivehess(H), and single printers on respiratory(A), mouth and anus(D), lie scale(L), mental irritability(J). 8. According to education shows the difference, eg high school scored higher on eyes and skin (B), mental irritability(J), depression(K), nervousness(E), collage and over scored higher on multiple subjective symptom(I ), respiratory (A), mouth and anus (D), lie scale (L), aggressiveness (F), irregular life (G), and middle school scored high on digestive (C), impulsiveness (H).

Since introducing the offset frontal impact test in EuroNCAP in 1997, the vehicle has been constantly changing according to its usage and purpose. As of 2019, many vehicles have been released to the public, which has led to a large structural mass difference between small, medium and large vehicles. Also, the geometry of the front of the vehicle is completely different for each vehicle and tends not to be perfectly aligned at frontal collisions. The difference in mass of each of these vehicles and less performing structures for offset crashes have led to dramatically worse outcome in a car to car offset frontal impact tests. Even though a decade later passenger cars have become much safer due to consumer test programs and regulatory requirements, the aggressiveness and compatibility that can cause damage to the opponent car in the event of car to car collision is not considered in the above-mentioned section, and therefore much improvement is needed. After many years of study to solve this problem, EuroNCAP has developed a new mode MPDB offset front test that considers the aggressiveness and compatibility that can affect the opponent cars that have collided. This paper introduces the development process of aggressiveness and compatibility evaluation method of MPDB in EuroNCAP which will be implemented from 2020. Several impact tests have been conducted at different test conditions to rate the vehicle structure performance only focused on aggressiveness and compatibility of MPDB.

The purpose of this study was to perform a convergence study for the investigation of the trend of research topics related to thyroid cancer in Korea. We collected related research papers from DBpia and employed LDA-based topic model. In result, we identified four research topics, each of which concerns "Surgery", "Disease aggressiveness", "Survival analysis", and "Well-being of patients". With multinomial logistic regression, we found significant time trend, where "Surgery"-related topic was popular before 2000, topics regarding "Disease aggressiveness" and "Survival analysis" were frequently addressed in the 2000s, and "Survival analysis" and especially "Well-being of patients" have been pursued since 2010. The findings would serve as a reference guide for research directions. Future work may examine whether the recent change in research topics is observed in other diseases.

White rot or stem rot caused by Sclerotinia sclerotiorum is one of the most destructive fungal diseases that have become a serious threat to the successful cultivation of oilseed Brassicas. The study was designed with an aim to investigate the association between the pathogenic aggressiveness and pathogenicity determinants of this pathogen specifically in Brassica for the first time. For this, a total of 58 isolates of S. sclerotiorum from different geographical regions were collected and purified. These isolates were inoculated on a Brassica juncea cv. RL-1359 and they exhibited high level of variation in their disease progression. The isolates were grouped and then 24 isolates were selected for the biochemical analysis of pathogenicity determinants. The isolates varied significantly with respect to their total organic acids, oxalic acid production and pectin methyl esterase and polygalacturonase activity. The oxalic acid production corresponded to the disease progression of the isolates; the isolates with higher oxalic acid production were the more aggressive ones and vice-versa. This is, in our knowledge, the first study to establish a correlation between oxalic acid production and pathogenic aggressiveness of S. sclerotiorum on B. juncea. However, the pectinases' enzyme activity did not follow the trend as of disease progression. These suggest an indispensable role of oxalic acid in pathogenicity of the fungus and the potential to be used as biochemical marker for preliminary assessment of pathogenic aggressiveness of various isolates before incorporating them in a breeding program.

Snow molds are the most important winter diseases of turfgrass in the United States and Canada. Eight isolates of three snow mold fungal species (three isolates of Typhula ishikariensis, three of T. incarnata, and two of Microdochium nivale) were collected from infected turfgrasses on golf courses. The isolates were evaluated for their relative aggressiveness on three cultivars (L-93, Penncross, and Providence) of creeping bentgrass (Agrostis palustris) under the same controlled conditions. Four plant ages (15, 19, 23 and 27 week-old plants from germination to inoculation) were evaluated for their susceptibility to the three pathogens and for the recovery of the plants. Regardless of age or cultivar of the host plant, M. nivale was found to be more aggressive and faster to infect and colonize than Typhula species. After three weeks recovery, M. nivale-inoculated plants showed higher disease severity than plants inoculated with the two Typhula species. Plants infected by Typhula species displayed no significant difference in disease severity. As creeping bentgrass plants get older, the severity of disease caused by three snow molds gradually decreases. This effect was observed in all cultivars tested, suggesting expression of age-related resistance as the bentgrass plants matured.
