This research aims to develope a maturity evaluation model on the technology management competence (MEMTMC) and to investigate the relationship between technology management competencies and maturity evaluation level in Korean firms. After research framework building through literature review and field study focusing on interview process, a maturity evaluation model was suggested, including technology management competency factors such as vision and strategy, leadership, resources, projects, performance management, and systematic procedures. Through the empirical study on the 111 Korean firms, the MEMTMC model was tested and some hypotheses were examined. As a result of the research, we found that the MEMTMC is significant statistically to evaluate the technology management competencies of firms from a practical point of view. Additionally, these findings suggest that firms can build up their technology management competencies, including the vision and strategy, leadership, resources, projects, performance management, and systematic procedures in order to raise their maturity level of technology management competencies. But this research has some limitations such as this MEMTMC has not considered separately the variety of industry, not enough survey respondents and 5 level group firms etc.

The purpose of this study was to examine educational performance of key competencies in the situation by introducing NCS of junior college. And also, this study aimed at investigating the effects of individual characteristics on the relationship between characteristics of key competencies based on NCS and educational transfer. Data was collected from samples of 389 freshman and sophomore students who took the classes about communication skills and problem solving skills of key competencies. All of the students major in secretarial science. Based on the collected data, this study analyzed structural equating model, using AMOS Graphics. The result of analysis showed that there was a significant positive effect of educational training characteristics on educational transfer in some research models planned in this study. The findings in analysis of mediating effect showed that there was a full mediation effect of determinacy of career attitude maturity, and there was a partial mediation effect of readiness of career attitude maturity. Based on the result, this study proposed theoretical and practical ways considering individual characteristics for establishment and development of NCS.

The strength development of concrete is influenced by temperature and cement type which greatly affect hydration degree of cement. There is not pertinent concrete strength management method in korea. There are several methods for estimating the in-place strength of concrete. One such method is the maturity concept. The maturity concept is based on the fact that concrete gains strength gradually as a result of chemical reactions between cement and water; and for a specific concrete mixture, strength at any age and at normal conditions is related to the degree of hydration. The rate of hydration and, therefore, strength development of a given concrete will be a function of its temperature. Thus, strength of concrete depends on its time-temperature history. The goals of the present study are to investigate a relationship between strength of high-strength concrete and maturity that is expressed as a function of an integral of the curing period and temperature and predict strength of concrete.

This purpose of this study was to examine the effects of maternal attitude toward parenting and children's basic living habit on children's social maturity. Subjects were 252 mothers of 5-6 year-old children in Seoul and Gyeonggi-do. The data obtained were analyzed by Cronbach's alpha, Pearson's correlation, t-test, and multiple regression. The major result of this study was that exercise and conversation ability of children had close relationships with several elements: birth order of children, educational background of mother, and affectionate and autonomous child-rearing attitude. Especially, mother's educational level and mother's warmth and self-regulatory child-rearing attitude were the most strongly related variables for children's social maturity.

This study was carried out to elucidate the correlation between Germination Index(G.I.) and CO2 emission for evaluation of the maturity of compost products. 13 compost samples was used for this experiment. The G.I. test was carried out on the basis of T-N 200ppm. As a result of this research, we found that CO2 emission method was good simple indicator for evaluation of maturity of compost materials, in spite of G.I. The obtain results are summarized as follows ; 1. The correlation value between the G.I. and the CO2 emission was R2 = 0.776. 2. The correlation value between EC(Electric Conductivity) and G.I. was R2 =0.7. 3. The equation calculated from G.I. and CO2 emission was G.I. = -16.7(InCO2) - 6.87. 4. From these results, we found the possibility of estimation for the value of G.I.(T-N 200ppm) from CO2 emission volume under specific condition.

In this study, we aimed to develop a maturity classification model for tomatoes using hyperspectral imaging in the range of 400 - 1,000 nm. Fifty-seven tomatoes harvested in August and November of 2021 were used as the sample set, and hyperspectral data was extracted from the surfaces of these tomatoes. A combined method of SNV (standard normal variate) and SG (Savitzky-Golay) methods was used for the pre-processing of the hyperspectral data. In addition, the hyperspectral data were analyzed for all maturity stages and considering bandwidths with different FWHM (full width at half maximum) values of 2, 25, and 50 nm. The PCA (principal component analysis) method was used to analyze the principal components related to maturity stages for the tomatoes. As a result, 500 - 550 nm and 650 - 700 nm bands were found to be related to the maturity stages of tomatoes. In addition, PC1 and PC2 explained approximately 97% of the variance at all FWHM conditions and thus were used as input data for classification model training based on the SVM (support vector machine). The SVM models were able to classify tomato maturity into five stages (Green, Turning, Pink, Light red, and Red) with over 95% accuracy regardless of the FWHM condition. Therefore, it was considered that hyperspectral data with 50 nm FWHM and SVM is feasible for use in the classification of tomato maturity into five stages.

연구목적: 적산온도를 이용하여 시멘트 종류별로 고강도 콘크리트(70MPa)의 초기 강도를 정확히 예측하여 콘크리트 품질의 신뢰성 확보, 거푸집 탈형 시기, PS 콘크리트의 텐셔닝 타임, 도로 보수 후 교통의 진입 시기 등을 정확히 도출하여 경제적이고 안전한 건설공사에 도움을 주고자 한다. 연구방법:시멘트 종류별 수화열을 재령마다 측정하여 적산온도를 계산하고, 재령별 콘크리트의 강도를 측정하여 임의의 적산온도에 상응하는 강도를 예측한다. 연구결과: 도로보수에서 교통개방에 필요한 시간을 추정하는데 있어서, ASTM C1074에서는 고강도 콘크리트의 경우에는 이론적으로 16.4시간으로 예측하였으나, 본 연구에서는 OPC인 경우의 적산온도 307, 14.4 시간, LHPC인 경우의 적산온도 2700, 34시간, ESPC인 경우의 적산온도 200, 8시간 정도로 계산되었다. 결론:고강도 콘크리트를 사용한 구조물의 거푸집 탈형시기 및 도로보수의 교통개방 시기는, ACI Committee 347을 적용한 설계기준강도 40MPa이하의 보통콘크리트의 경우보다 월등히 빨라질 수 있다.

본 논문의 목적은 네일리스트의 성숙도가 업무성과와 고객지향성에 미치는 영향에 관하여 실증적으로 검증하는 것으로 하였고, 전국에 있는 네일샵에 근무하는 성인 여성 네일 미용 종사자(네일리스트) 300명을 대상으로 분석을 하였다. 연구 가설을 규명한 결과, 네일리스트의 성숙도가 업무성과에 유의한 영향을 미친 것으로 나타났으며, 네일리스트의 성숙도가 고객지향성에도 유의한 영향을 미치는 것으로 나타났다. 이러한 연구 결과는 초보 네일리스트들이 점차 증가하고 있는 현 상황에서 네일리스트의 성숙도는 시술 결과나 매출적인 부분에서도 직접적으로 나타날 수 있기 떄문에 네일리스트의 성숙도에 대한 개선 방안은 고객지향성이나 업무성과에 밀접한 영향을 줄 것으로 사료된다. 성숙도가 네일 미용이나 다른 미용(피부, 헤어 등)의 관점에서 연구된 선행 연구가 많이 부족하여 논의에 어려움이 많았기에 향후에는 좀 더 심층적인 후속 연구가 진행되기를 기대한다.

스마트팩토리는 가장 빠르게 발전하고 변화하는 4차 산업혁명 분야 중 하나이다. 스마트팩토리에서 도입정도와 성숙도 수준 평가는 중요한 부분에 해당한다. 본 논문에서는 국내 스마트팩토리를 도입한 중소기업들을 대상으로 설문 조사를 진행한 데이터를 바탕으로 스마트팩토리 도입 현황과 새로운 성숙도 평가 모델 기반 군집분석을 진행하였다. 설문에 응한 스마트팩토리 도입 기업의 약 68% 기업들이 기초수준에 해당하였고, 21% 정도만이 중간1 수준이었다. 대다수 중소기업들이 중간1로 진입하지 못한 가장 큰 이유로 자금부족을 꼽았다. 군집분석 결과, 군집별 패턴은 유사하지만 정도의 차이에 따라 '상, 중, 하' 3개로 군집됨을 확인할 수 있었고, 6 도메인 중 프로세스가 상대적으로 성숙도가 가장 높았고, 데이터가 가장 낮은 수준을 보였다. 이를 통해 6개 도메인 기반 새로운 스마트팩토리 성숙도 평가 모델을 활용하여, 보다 구체적이고 정량적인 성숙도 수준 측정 및 분석이 가능함을 보였다.
