Little is known of the life history of Garcinia kola; the objective of this study, therefore, was to assess the fruiting age and tree size of the species in a coastal humid tropical climate plantation condition. A total 103 trees were used in the study viz; 80 ten-year-old trees at reproductive maturity onset and 13 thirty-year-old trees with several cycles of reproduction that constitute two independent variables. Data collected were age of onset of flowering and size at reproductive maturity onset. Relative size at reproductive maturity onset (RSOM) was estimated as size at reproductive maturity onset (SOM) divided by asymptotic maximal size (AMS). Data analysis was conducted using pairwise t-test and principal component analysis (PCA). Reproductive maturity onset (flowering) was recorded in the ten-year-old stand eight (8) years after planting. Mean size at reproductive maturity onset (SOM) was height 5.32±1.7 m, dbh 0.11±0.03 m, total number of branches was 29.6±7.3, crown depth 5.24±1.05 m, crown diameter was 4.78±0.7 m, branch diameter 0.098±0.01 m, leaf length 0.13±0.02 m, leaf breadth 0.37±0.01 m, twig length 0.35±0.11 m and leaf per twig 6±0.84 and asymptotic maximal size (AMS) was height 19.85±0.76 m, dbh 0.95±0.09 m, total number of branches 62±5, crown depth 18.83±0.7 m, crown diameter 12.5±1.64 m, branch diameter 0.5±1.6 m, leaf length 0.16±0.023 m, leaf breadth 0.45±0.12 m, twig length 0.37±0.11 m and leaf per twig 19±7.5. Pairwise t-test analysis showed there was significant differences between SOM and AMS in all growth factors except leaf length, leaf breadth, and twig length. Highest relative size at reproductive maturity onset (RSOM) was recorded in leaf length 0.82, twig length 0.82, and leaf breadth 0.80, while, the lowest was branch diameter 0.11. Four components out of the total of eleven were extracted to explain the relationship in RSOM: Principal component one (PC1) explained 37.23%; PC2 26.4%, PC3 22.73%, and PC4 13.64%.

In order to analyze the factors influencing career maturity of general high school students, this study verified the moderated mediating effect of career exploration efficacy by the frequency of conversation with parents in the process of self-awareness and class attitude affecting career maturity. For the study of the second year of general high school, the results of verifying the moderated mediating effect using SPSS 22 and Model 7 of PROCESS macro from the results of the first year survey of the Korea Education and Employment Panel (KEEP) II are as follows. First, positive self-awareness and class attitude had a positive effect on career maturity. Second, career exploration efficacy mediates self-awareness, class attitude, and career maturity. Third, in the relationship between self-awareness and career maturity, there is no moderated mediating effect on career exploration efficacy by the frequency of conversation with parents. Fourth, in the relationship between class attitude and career maturity, a confrontation-moderated mediating effect on career exploration efficacy by conversation frequency with parents appears. Based on these studies, implications and future tasks for career maturity of general high school students were proposed.

The purpose of this study was to investigate the relationship between career barrier and career maturity of the adolescents who were concretely worried about their career and occupation. 672 middle school students were participated to analyze the Pearson Correlation and Multiple Regression Analyses with data collected by the questionnaire. This study revealed the following results. First, the correlational analysis showed that career barrier associated negatively with career maturity. Second, the multiple regression analysis revealed that sub-elements of career barrier which the adolescents conceived, such as the shortage of self-understanding, the shortage of self-reliance, gender-role conflict and gender discrimination, and the shortage of career and occupational information were significantly effecting their career maturity. Third, as a result of multiple regression analysis to estimate the explanability of career barrier on career maturity, career barrier among various independent factors which were correlated statistically with career maturity showed most effects on it. Also, school academic achievement was confirmed as a significant factor effecting the career maturity. Above these results imply that the perception on the career barrier of the adolescent should be reduced for increasing the career maturity. For this, career education and counselling should be positively intervened and reinforced through the school curriculum and activities.

With the overwhelming development of information technologies, the need for software development that can deal with diversified and complex business processes has increased dramatically. As a result, companies prefer softwares that can handle far more complex processing ability and also it should be stable as well as easier to maintain. These ambivalent requirements keep the software development organizations from assessing the quantitative abilities, so that under the support of the U.S. Department of Defense the Capability Maturity Model (CMM) and Capability Maturity Model Integration (CMMI) have been developed. The CMMI upper levels for the software development companies will be evaluated to be excellent and authenticated, which drives the companies to get and maintain high levels of maturity. In this paper, a case study for a domestic software company has been exploited how to achieve CMMI level 4 and what kind of factors have been played an effective role. These issues at the domestic and international software and maintenance program, can influence the trustworthiness and marketing effects for the global market. In this paper, the company's actual case study will give clues to find out the important factors for the development and maintenance of software companies maturity levels.

In this study, we analyzed determinant factors of leverage ratio and debt maturity for Korean firms in the simultaneous equation system using 2SLS (two stage least square) method under assumption that two variables are jointly determined in the capital structure decision. As a result of the analysis, we found that leverage ratio and debt maturity are positively related. Also, as for determinant factors of debt maturity, agency cost hypothesis, asset maturity matching hypothesis, signalling and liquidity risk hypothesis are all generally supported, and further leverage ratio are significantly positively related with firm size, but negatively related with default risk. However, when we divided samples into groups according to bank debt level and Chaebul affiliation, with contrast to existing study which worked on similar issues with OLS, we found no evidence supporting the argument that the information asymmetry problem is less severe in firms with more bank debt, whereas information asymmetry and financial constraint problems are more severe in non-Chaebul affiliated firms.

The purpose of this study was to investigate visual evaluation according to various methods of motif presentation and the value contrast between the motif and background. The instruments developed for this purpose were two sets of stimuli and a response scale. the first set consisted of pattern stimuli. they were eight photographs of floral patterns constructed by using six different motif presentation methods and two different value contrasts. The second set had eight clothing stimuli, photographs of clothings with the above floral patterns. The 7-point sementic differential scale of 19 bipolar adjectives was used as the response scale. The data was analyzed by factor analysis, ANOVA and T-test. The major findings from this study were as follows; 1. Four factors emerged to account for the dimensional structure of the floral pattern image. These factors were attractiveness, tenderness, attention, and maturity. among them attractiveness and tenderness were the major dimensions 2. The patterns and the clothings had no significant difference from each other in terms of attractiveness and tenderness, but in terms of maturity and attention. The pattern presented a cute and sober image, but the clothing presented mature and gorgeous image. 3. methods of motif presentation had significant effects on all the factors. The pattern by shading method gave the most attractive and soft image, the one by line the most soberest, the one by area the most gorgeous, the one by collage the most unattractive, hardest, and cutest, and the one by mosaics the maturest. 4. The value contrast between the motif and background had no significant effects on attractiveness and maturity, but on tenderness and attention. The patterns with a high valued background presented a soft image, but the one with a low valued background a hard image. The patterns with a low valued area presented gorgeous image.

In this paper, 228 cooperations supported by government were surveyed on the cognition levels of 5 factors for successful policies that support small business cooperation. Goal importance, awareness stage of importance, and current concerning level were scored to each question of factors. Using the results of previous studies, the maturity of each success factor, and the forecast time to mature and maturity of each question were analyzed. The results were compared with the results of a study precedent. Moreover, the changes in the participants' recognition levels were reviewed between before and after government's support. These comparative studies reflect government policies. Despite the government's supporting policies aided on building cooperation positively, the participants still worry about the decreasing government support. To allay these concerns, government policies should be implemented continuously to promote cooperation rather than a one-time support.

This study was conducted to identify the determinants of regional body fat distribution of obesity(upper body obesity and lower body obesity) for adolescents. The macronutrient consumption pattern utilized the most important variables to test for potential determinants. A total of 726 adolescents living in rural areas in Korea had been observed for four years from 1992 to 1996 about their diet, sexual maturation, serum components and physical growth. The study design was similar to that of a case control study. Logistic regression analysis were used as an analytical method to identify the determinants of upper body obesity and lower body obesity. Odd ratios were estimated from the regression to identify the determinants of upper body obesity and lower body obesity. Odd ratios were estimated from the regression to identify the risk factors. Fat consumption pattern was the most frequent one among the three macronutrient consumption pattern of carbohydrate, fat and protein. Prevalence of obesity for the subjects was 9.5%. Prevalence of upper body obesity was higher in malestudents than in female students. On the other had, prevalence of lower body obesity was higher in females. The results of the logicstic regression analysis showed that the risk factor for upper body obesity was sexual maturity rather than dietary factors. None of the factors included in the analysis for lower body obesity appear to be the risk factor. The result may suggest that to develop a determinant model for obesity of adolescents, the model should include a wider range of variables other than diet, sexual maturity and changes in blood serum.

This study examines cultural differneces in psychosocial maturity experiences between collectivistic and individualistic cultures. Personal, relational, and social dimensions were assessed to explore psychosocial maturity experience of elderly Korean residents in Korea and Canada who were psychosocially well developed through in-depth interviews and a content analysis. According to the results, there were diverse similarities and differences in the psychosocial maturity of elderly Korean residents between the two cultures. First, psychosocially mature elderly residents in both cultures showed positive self-concept and self-satisfaction. However, there were differences in their meaning. Second, in terms of interpersonal relations, the most important and satisfying relationship was the spousal relationship for both cultures, and relationships with children were satisfying. However, there were differences in the meaning of relationships between the two cultures as well as gender differences. Third, psychosocially mature elderly residents in both cultures reported psychosocial factors such as mature aging as a social dimension. Elderly residents in Korea regarded mature aging as a relationship oriented phenomenon, whereas those in Canada reported social attitudes toward mature aging. In addition, elderly residents in both cultures reported greed and harm to others as immature aging. Elderly residents in Korea regarded relational discord as immature aging, whereas those in Canada regarded it as demanding adult treatment from future generation. In terms of transcendence, adjustment was reported as living by going with the flow. Elderly residents in Korea reported adjustment based on fatalism, whereas those in Canada showed some religious meaning. Finally, psychosocially mature elderly residents showed a positive view, acceptance and life integration. These results are discussed from the perspective of cultural differences.

This study was carried out to figure out the relationship between EAmaturity, information management capacity, and information performance, and find the effect between these variables and the reciprocal causation. The study found that EAmaturity has a positive effect on information resource management and performance. In other words, the effect of input, calculation, management and utilization factors on information planning in EAmaturity showed that calculation, management and utilization factors have a significant effect on the information planning. While the effect of input, calculation, management and utilization factors on information introduction and management showed that only both calculation and utilization have a significant effect on the information management factor. It says that EAinput in EAmaturity does not play a big part in the planning stage, as well as not go through a series of process that is connected to the maturity stage by immediate field application. Consequently, EAmaturity varies from the level that EAcreates introduction and performance according to organization. This suggests that the maturity and performance can be also changed by the level that EAcreates information performance by accepting and using this capability within organization as well as the capability to introduce and fully perform the EAsystem presented in enterprise architecture framework of public sector.
