The purpose of this study was to examine that multiple mediating effects of self-determination and self-efficacy in the relationship between the parental control and career maturity. In the study, 747 university students in Daegu, Busan and Seoul area were surveyed on their perceived level of parental control, career maturity, self-determination and self-efficacy. Data were analyzed using descriptive statistics, one-way ANOVA, and Pearson correlation analysis with SPSS 25.0 program, Hayes'Process Macro program and bootstrapping. The major results of this study were as follows; First, there were significant differences in college student's career maturity by grade, major, experience in career-related services and part-time job experience period. Second, there were significant correlations between parental control(behavioral control and psychological control), career maturity, self-determination and self-efficacy. Third, self-determination and Self-efficacy had multiple mediating effects in the relationship between parental control and career maturity. In conclusion, this study found multiple mediating effects of self-determination and self-efficacy in the relationship between parental control(behavioral control and psychological control) and career maturity. It was also found that parental behavioral control had a positive effect on career maturity by increasing self-determination and self-efficacy while parental psychological control had a negative effect on career maturity by decreasing self-determination and self-efficacy.

The present study investigated the digital color characteristics corresponding to different maturity stages and maturation levels of white croaker Pennahia argentatus specimens collected from the Southern Sea of South Korea. Maturity stages were determined using photomicrographs depicting ovarian developmental phases and compared with digital color values. The specimens ranged in body length from 21-36 cm, with mature ovaries observed within the 24-30 cm length range. To differentiate the maturing, mature, spawning, and post-spawning stages of the gonads, boundary lines were established based on specific coordinates. For the ovaries, a dividing line was drawn through (-10, -10) and (15, 5), described by the equation Y=3/5X-4; while for the testes, the line passed through (20, 0) and (0, 15), indicated by the equation Y=-3/4X+15. However, the visual determination of the maturity stages proved challenging due to overlapping color values. Consequently, this study underscores the efficacy of employing digital color measurements over subjective visual assessments to evaluate the maturity of white croaker gonads and offers more quantitative insights.

Experiments were carried out to establish physiological maturity determination criteria with reference to visibly easy measurement in barley in 1980 at Suweon. Thirty-three cultivars and lines from 500 crossing blocks were classified into 4 heading groups, and 5 variables; moisture content, discoloration of awn, exsertion, lemma and flag leaf were measured. There were highly negative correlations between heading date and ripening periods (r=-0.656$^{**}$ ), so early heading types had longer ripening periods. Comparing with the variables used for maturity determination, moisture content and discoloration of lemma were most sensitive to development of grain-filling. Those two variables, alone or in combination could be used to screen many genotypes of barley for physiological maturity. In determination of maturity with reference to visibly easy measurement, color of lemma changed stably and was the most useful way and discolor of flag leaf increased the accuracy of determination. The color of lemma at this time was Grayish yellow, and the mean moisture content was about 33 percent in 33 barley cultivars and lines.

Manure-based composts can have detrimental effects on the agricultural lands and crops if they are applied without proper stabilization process. Composting is well-known method for the stabilization of manure-based composts and the extent of composting could be examined by maturity test. Among various methods to examine compost maturity, the performances of two mechanical methods (Solvita and CoMMe-100) were examined and the test results were compared with seed germination test. The mechanical methods are considered to be simple and relatively objective. Also they are cost- and time-efficient. Ten commercially available composts collected in Korea were used for this study. Basically, the maturity determined with these mechanical methods was in good agreement with the seed germination test. However, it appeared that the index levels of compost maturity indicated more maturity by CoMMe-100 than Solvita for the same compost. The differences between maturity index levels determined by both methods were able to be minimized through extending the reaction time for CoMMe-100 and adjusting index level for maturity determination in the standard color chart.

Purpose: Demirjian's dental maturity scores and curves have been widely used for human age determination. Several authors have reported considerable differences between the true and estimated age based on the Demirjian curves, which have been accounted for by ethnicity. The purpose of the current study was to assess the role of ethnicity-specific dental maturation curves in age estimation of Saudi children. Materials and Methods: A sample of 452 healthy Saudi children aged 4 to 14 years were aged based on the original French-Canadian Demirjian curves and several modified Demirjian curves specified for certain ethnic groups: Saudi, Kuwaiti, Polish, Dutch, Pakistani, and Belgian. One-way ANOVA and a post hoc Scheff$\acute{e}$'s test were used to assess the differences between chronological age and dental age estimated by the different curves (P<0.05). Results: The curves designed for Dutch, Polish, Saudi, and Belgian (5th percentile) populations had a significantly lower error in estimating age than the original French-Canadian and Belgian (50th percentile) curves. The optimal curve for males was the Saudi one, with a mean absolute difference between estimated age and chronological age of 8.6 months. For females, the optimal curve was the Polish one, with a mean absolute difference of 7.4 months. It was revealed that accurate age determination was not related to certain ethnicity-specific curves. Conclusion: We conclude that ethnicity might play a role in age determination, but not a principal one.

Combining ability study was carried out on the components of synchronization in maturity and determinate growth habit in mungbean, using 6$\times$6 diallel cross. Both additive and non-additive gene effects were found conditioning the inheritance of days to first flower, days between first pod and 90% pod maturity (DDd1), plant height from first pod stage to 90% pod maturity (DDhl, DDh2, and DDh3). Only non-additive gene action was important in degree of determination from first pod stage to 90% pod maturity (DDd2). While only additive action was important in plant height at first flower. The predominant additive gene action was observed in all traits but non-additive was significant in only DDd$_2$. For synchronization in maturity, determinate growth habit, and their components, the best combiners were NM92, VCl560D, and NM89, whereas the best indeterminate combinations were NM92 $\times$ NM89, NM92 $\times$ VCl560D, and NM92 $\times$ ML-5.

Maturity is expressed as the integral of time and temperature of concrete above a datum temperature. The maturity concept proposes that concrete of the same mix at the same maturity has the same strength, whatever combination of temperature and time makes up that maturity. In this study, the Nurse-Saul function which was proposed to account for the effects of temperature and time on strength developrnent is used in computing maturity. After existing various functions are considered to relate concrete strength to the maturity value, new strength-maturity function is proposed. Tests ;ire conducted in order to determine d datum temperature and compare prechction value with measured concrete strength. The constants in proposed prediction equation are determined from test results, and the equation is adopted to predict the strength of slab. The slab was cast in the laboratory from the same batch of mold, and cores are cut from slab in order to estimate the actual strength. These values are used to compare with predicted value. The present study allows more realistic determination of early-age strength of concrete and can be efficiently used to control the quality in actual construction.

This study investigated the digital color profiles corresponding to different maturity stages and levels of brown croaker Miichthys miiuy specimens collected from the Southern Sea of South Korea. Maturity stages were determined using photomicrographs of ovarian developmental phases, which were compared with digital color values. Brown croaker specimens ranged from 24 to 81 cm in standard length; mature ovaries were predominantly observed in specimens that exceed 40 cm in length. Monthly ovary color values were primarily concentrated in the 1st and 4th quadrants, with both a^* and b^* values falling within a range of ±15 centered on the origin. Similarly, the testes color values were predominantly situated in the 4th quadrant, with a^* and b^* values ranging from -5 to 15 and 10 to 14, respectively. While the color values of the mature and spawning stages overlapped within a narrow range, distinguishing between them required both the color value and monthly color value distribution to be considered. Thus, this study underscores the efficacy of digital color measurements for assessing brown croaker gonad maturity, and provides more quantitative insights compared to subjective visual assessments by humans.

Digital color analysis was used to determine the gonadal maturity stages and levels of robust tonguefish Cynoglossus robustus specimens collected from the South Sea of Korea. Maturity stages were determined using photomicrographs depicting ovarian developmental phases and compared with digital color values. Speciments of C. robustus ranged in total length from 21 to 40 cm, with mature ovaries predominantly observed in specimens exceeding 30 cm in length. Monthly color values of the ovaries were primarily concentrated in the 1st and 4th quadrants of the color space, with a^* and b^* values ranging within ±20 and ±15, respectively. The color values of the testes were predominantly located in the 1^st and 4^sth quadrants, with a^* and b^* values ranging from -10 to 10 and -5 to 10, respectively. Although the color values of the mature and spawning stages overlap within a narrow range, distinguishing between them requires consideration of both color values and their monthly distribution. This study underscores the effectiveness of using digital color measurements over subjective visual assessments to evaluate the maturity of C. robustus gonads, thereby providing more quantitative insights into their reproductive biology.
