This study analyzed the structural types of happiness that kindergarten teachers feel and the features of each happiness type to increase the happiness of kindergarten teachers. The subjects of this study were 41 kindergarten teachers working at a kindergarten in D city. They were chosen randomly. The Q-methodology, which allows in-depth measurements of people's subjective perception of happiness, was employed. The results and further analysis revealed 4 structural types of happiness: 1) self-realization type, who feels happiness while setting goals and achieving them; 2) inner satisfaction type, who thinks that happiness can be found in the current status; 3) social relationship type, who emphasizes a good relationship with others; and 4) personal belief type, who emphasizes living life in one's own style without being bothered by others.

This study was designed to analyze the types of concepts about earth science related to seasonal changes, so as to develop a generative learning model focused on dissolving cognitive conflicts between the aforementioned concepts through debates and using said debates to find out how effectively the model works. There are 100 types of earth science concepts concering seasonal changes, 66 of which are unscientific in nature, including misconceptions. Through a second field trial and a research and development (R&D) process, a test on these concepts was developed, consisting of 14 items. For the experimental group, a four-phase generative learning strategy that reflects the types of earth science concepts and cognitive conflicts between such concepts was developed through pre-analysis and discussion, respectively. On the other hand, a traditional teaching and teaming strategy was used for the control group. A meaningful statistic gap found between the two groups through a covariance analysis, the significance level of which was 0.05. This result may be interpreted to mean that the generative teaming strategy is a possible alternative for correcting misconceptions about scientific concepts of seasonal changes.

The purpose of this paper is to classify the traffic condition in freeway by the impacts of road weather. The factor analysis showed that weather factors, which are considered as influential, are identified as weather condition (rain or clear), temperature and sight distance with RWIS and VDS data in Seohae bridge used. The result of ANOVA shows that weather is dividedinto clear and rainy; temperature into below and equal or above $5^{\circ}C$ and sight distance into below or equal or above 10km. Based on those factors, the freeway traffic condition has been classified as five different types. The flow-speed model for each traffic conditions was proposed, which was not significant due to the lack of smaple data. Although not sufficient, the methodology to categorize traffic situation model presented in this paper may shed light on the idea for the future and can be used for proper traffic management for each weather condition.

The purpose of this study was to identify the Kolb's learning style and preference for instructional methods of undergraduate nursing students. Data were collected from 174 students at a university in D city using a structured questionnaire from October 19 to October 21 2015. Learning style ratio of nursing students was accommodator 34.5%, converger 33.9%, assimilator 16.1%, diverger 15.5% and preference scores for instructional methods were discussion 7.27, direct instruction 7.26, peer teaching 7.22, independent study 6.54, project 6.25, instruction through technology 5.77, game 5.45, simulation 4.23. A significant difference was found in experience of flipped learning between four learning styles groups of nursing students. However, there was no significant difference in the preference of instructional methods between the four learning styles groups. Most of the students were in the middle range of the learning styles. The assessment of nursing students' learning styles is expected to help educator to plan teaching strategies.

To reject the Doppler frequency spectrum dispersion of clutter caused by high-speed antenna rotation of MTI radar system due to terrain characteristics, signal processing parameters(MTI filter constant, M/N detector ration, K-factor and offset of CFAR) are adjusted for the optimal elimination of the ground clutter. For this investigation, logging equipment is designed and utilized for the collection of classified ground clutter data. Test case is devised through Matlab simulation for the classified analysis and optimization of clutter rejection. Then indoor radar test and outside test in accordance with terrain characteristics are repeatedly performed for the verification of the test. This whole process is through the evolutional development model and repeated for the optimization. Final result is that ground-clutter rejection capability is 5.6 times(7.5 dB) better than that of existing radar system.

This study was attempted to clarify differences in sizes and shapes of foot between 20's and 60-70's women and analyzed the characteristics of elderly women's foot shapes as compared with those of young. The 2D data were 101 elderly and 101 young women in Seoul and Gyeonggi-do. The results are as follows: Firstly, the foot length of the elderly was shorter than that of the young, the foot breadth and the heel width were widened, but the toes breadth became smaller and the deformity of the toe 1 and the first metatarsal part appeared. Secondly, in the Foot Index, there was a significant difference in age group, the young is more than the elderly in the narrow type, standard type, the elderly women showed more than three times the young in the wide type. Thirdly, in the factor analysis for the foot type classification, 'foot length' factors in both age groups were large. Next, young group were influenced by 'toes breadth', lateral ball breadth' factors, elderly group was influenced by the 'lateral ball breadth', 'medial ball breadth' factors. Lastly, in the cluster analysis of the elderly group, the types of sole were classified as W-Type(20.8%, wide foot and toes, large heel), H-type(20.8%, small toes breadth, heel), D-type(31.7%, long length and wide lateral ball) and A-Type(26.7%, which is found only in the elderly, small length and large toes angle). As a result, it is necessary to design the shoes that match the characteristics of the soles of the elderly women.

The human resources of an enterprise is very important to survive in these days of business environment. This study investigates the influence of four behavioral types in MBTI (Myer-Briggs Type Indicator) and working conditions on organizational effectiveness. Job satisfaction and immersion have been regarded as a key conception of organizational effectiveness. The focus of this study is to investigate the effects of R&D employee's four behavioral types in MBTI and working conditions on organizational effectiveness. The results of this study show that organizational effectiveness is influenced by personality types and working conditions. According to the result, First, about the analysis of differences in job satisfaction, EP (Extraversion Perceiving)-type (3.56) and EJ (Extraversion Judging)-type (3.43) are higher than IJ (Introversion Judging)-type (3.07) and IP (Introversion Perceiving)-type (3.03) of four behavioral types in MBTI. So an enterprise makes various efforts to enhance job satisfaction for IJ (Introversion Judging)-type and IP (Introversion Perceiving)-type. Second, For improving the organizational effectiveness that is job satisfaction and immersion, an enterprise must make favorable working conditions to each four behavioral types in MBTI of R&D employees. In order to improve job satisfaction, the enterprise will provide IJ (Introversion Judging)-type with support for collegiality and IP (Introversion Perceiving)-type with good relationships with superiors. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type. Finally, in the case of EP (Extraversion Perceiving)-type, the enterprise must admit failure for efforts. In order to improve job immersion, the enterprise will provide IP (Introversion Perceiving)-type with good relationships with superiors, the vision of company and compensation for creative work. and also the enterprise gives autonomic authority to EJ (Extraversion Judging)-type.

Most information systems are component-based and developed by outsourcing, and developed software is maintained integrative. However, studies on cost measurement indicators and cost estimation model have not been performed sufficiently, which are foundational to enhance the productivity and efficiency of maintenance. This study suggests indicators to measure maintenance cost for component-based software and examines maintenance cost estimation model of component software by the measurement indicators suggested. In order to generate the indicators to measure the component-based maintenance cost, the previously proposed indicators are summarized comparatively. To estimate the measurement indicators of component-based software, it makes a comparison of the previously proposed indicators and arranges them. We classify the measurement indicators by how to apply according to maintenance types of component software and then we propose the cost measurement indicators. Moreover, we propose the cost estimation model according to the maintenance types of component software using the suggested measurement indicators suggested. With the suggested estimation model, a case study is performed and its validity is verified.

관상피내암종의 조직학적 분류에 있어서 그 기준으로써 공통적으로 사용된 소견은 핵등급, 면포형 괴사 및 성장유형이었다. 그러나 최근의 분류(Tavassoli, 1992; Tavassoli and Man, 1995; Poller 등, 1994; Holland 등, 1994; Silverstein 등, 1995; Millis, 1996)에서는 핵등급과 면포형 괴사만을 분류의 기준으로 사용하고 있고 성장유형은 포함시키지 않는 경향이 있는 것 같다. 이는 관상피내암종의 성장유형은 너무나 다양하고 혼합형으로 자라는 경우가 많아 관찰자간의 재현성이 떨어지고, 이와 반대로 핵등급이나 면포형 괴사는 관찰자간의 재현성이 비교적 높을 뿐만 아니라 여러 가지 생물학적 표지자와도 관련이 잘 지워지기 때문으로 생각한다. 관상피내암종의 분류나 등급매김에 있어서는 연구자마다 사용하는 용어가 다르고 그들이 정한 등급의 기준이 서로 다르나 대체로 세 등급으로 나뉘어짐을 알 수 있었다. 한편, 국내에서는 유방의 관상피내암종에 대한 연구가 미흡한 실정이므로 이에 대한 지속적인 자료의 축적과 연구가 필요하리라 생각한다.
