  • Recently the interferometric synthetic aperture radiometer with sub-Y-type antenna array was suggested to improve the spatial resolution than that of conventional Y-type with the same number of antenna elements. The sub-Y-type performance has been reported under a point source target. In this paper, the performance of sub-Y-type is evaluated under contiguous objects. The angular resolution of sub-Y-type with 52 antennas was compared with that of Y-type with the 40 antennas. The images of sub-Y -type and Y-type array were simulated under the contiguous objects. The sub-Y-type showed higher resolution than Y-type in the simulation and experiments. The sub-Y-type has high spatial resolution than Y-type in case of contiguous source as well as single point source.

  • The objectives of this research paper are to identify the types of the firm's new product development strategy and their characteristics about business strategy, to examine the effect of each type on new product outcomes, and to explore the contingency variable influencing the relationship between these types and new product outcomes. The result of the research are summarized as follows : First, in terms of both the resource allocation for product innovativeness and technology acquisition method, this study suggests 9 types of the firm's new product development strategies- Type 1 (pursuing low innovative products/relying on external technology), Type 2 (pursuing low innovative products oriented/relying on internal technology), Type 3 (pursuing low innovative products/relying on mixed technology), Type 4 (pursuing high innovative products/relying on internal technology), Type 6(pursuing high innovative products /relying on mixed technology), Type 7 (balancing low and high innovative products/relying on external technology), Type 8 (balancing low and high innovative products/relying on internal technology), Type 9 (balancing low and high innovative products/relying on mixed technology). Second, these 9 types are deeply associated with the firm's business strategic variables such as product differentiation and market differentiation, and exhibit different level of both technical and commercial performance of new products. Finally, the effects of these types on new product outcomes are different according to industrial environment and firms' characteristics with respect to size and technological capability.

  • The purpose of this study was to investigate teaching competence of faculty members based on TPACK which should be examined to ensure high quality in higher education. This study was conducted with a focus on TPACK, which integrate technology knowledge (TK), content knowledge (CK), and pedagogy knowledge (PK). Except insincere responses data from a total of 85 participants were used for data analysis in this study. K-mean cluster analysis method was used to examine how faculty members could be distinguished depending on TPACK type. Study results showed that there were three different types of faculty groups (well-balanced competence type, development required competence type, and lack of technology competence type). First, faculty members defined as well balanced competence type were more than the average level in TPACK. Second, faculty members belonged to development required competence type reported below the average level in TPACK. Thus, faculty members in this type were required to increase teaching competence. Finally, faculty members in lack of technology competence type were needed to enhance competence related to technology because their overall TK level was relatively low. This study examined what distinctive characteristics exited in each type depending on gender, teaching career, nationality, and age. Results from this study offered a basis for better understanding TPACK for enhancing teaching competence at the university level.

  • In this paper, we fabricated drag force type and pressure difference type gas flow sensor with dry etching technology which used Deep RIE(reactive ion etching) and etching stop technology which used SOI(silicon-on-insulator). we fabricated four kinds of sensor, which are cantilever, paddle type, diaphragm, and diaphragm with orifice type. Both cantilever and paddle type flow sensors have similar sensitivity as 0.03mV/V kPa. Sensitivity of the fabricated diaphragm and diaphragm with orifice type sensor were relatively high as about 3.5mV/V kPa, 1.5mV/V kPa respectively.

  • 본 연구는 중소기업 융합개념과 융합유형을 명확히 정립하고 중소기업 융합 사례를 유형별로 파악하여 융합을 통한 중소기업 경쟁력 증대에 도움이 되고자 하였다. 중소기업 융합유형은 Deloitte(2009)에서 제시한 기술과 산업, 가치개선과 창출 2가지 차원을 수용하여 기술은 투입, 산업은 산출의 차원에서 정의하여 중소기업 융합을 기술개선-시장확대형, 기술개선-시장창출형, 기술창출-시장확대형, 기술창출-시장창출형 4가지로 나누고 중소기업 융복합기술개발사업 우수사례집('11년 8월)에 소개된 기업들을 중심으로 융합유형을 분류하였다. 그 결과, 전체 13개의 사례 중 기술개선-시장확대형 5개, 기술개선-시장창출형 4개, 기술창출-시장확대형 3개, 기술창출-시장창출형 1개 순으로 나타나 중소기업의 경우 기술창출 보다는 기술개선에, 시장창출보다는 시장확대에 초점을 두고 융합이 이루어지고 있었다. 이러한 중소기업 융합 유형별 사례분석을 통해 파악할 수 있는 것은 중소기업이 융합을 통한 신기술이나 신시장을 창출하는 것이 매우 어렵다는 것이다. 따라서 중소기업은 기술개선을 통한 시장확대를 융합의 목표와 결과로 생각하고 있는 것으로 추정된다. 국가의 신성장동력을 육성하기 위해서 신기술이나 신산업 창출도 중요하지만 중소기업의 현실을 고려한 정책지원도 함께 고려해야 한다.

  • Purpose: This study aims to offer fundamental data to develop a career program that helps the dental technology students find a proper and desired job position and to be satisfied with their job. To this goal, we analysed the differences found between the personality type, major satisfaction, job satisfaction, and preference in job position among the dental technology students. Method: We conducted a survey using Myers-Briggs Type Indicator among the subjects who are sophomores and juniors of the dental technology department of a university in Gangwon province. Our analysis was grounded on 130 valid questionnaires. Results: The results are summarized as follows: In personality type ESTJ turned out the highest as 20.0%, while ENTP was the lowest as 0.8%. The preference was revealed as Extraversion (66.9%), Sensing (74.6%), Feeling (50.8%), Judging (61.5%) respectively. Of the general characteristics, only the religious or non-religious state was statistically meaningful as (p<. 05) in emotional type (F). No statistical significance was found in the major satisfaction. The job satisfaction was statistically meaningful as p<. 05 in Judgemental type (J). GPA was statistically significant as p<. 05 in the sensory type of the personality type. Desired job position was statistically meaningful as p<. 05 in emotional and cognitive types. Conclusion: We found a meaningful difference in the job satisfaction and the desired job position with respect to the personality type of dental technology students. However clear explanation of the correlations among these factors requires a more comprehensive survey and various approaches from the personality and psychology tests, which is to follow.

  • Recently, white LEDs, especially, warm white LEDs have been intensively investigated due to outstanding optical properties, long term stability and low power consumption. In this study, mixed type and patterned type of remote phosphors were prepared by screen printing process employing green and red phosphor. Each type of remote phosphor exhibited distinctive photoluminescence spectrum. For example, the mixed type of remote phosphor exhibited unique spectrum, while the patterned type showed expectable spectrum depending on the concentration of phosphors. This indicates that a small amount of red phosphor dramatically reduced the green photoluminescence in the case of mixed-type remote phosphor, whereas the effect was negligible in the patterned-type remote phosphor. The possibility of undesirable chemical reaction was further investigated by using scanning electron microscopy and X-ray diffraction.
