현대사회의 가장 큰 변화는 유비쿼터스 환경으로의 전환이라 하겠다. 이 환경의 변화는 결국 독자적인 경영에서 각 분야의 접목을 통한 융합경영의 시대를 열게 되는 결정적인 계기가 되었다. 소비자는 새로운 혁신제품에의 욕구가 끊임없이 나타나고 기업들은 이러한 변화에 대응하기 위한 부단한 노력을 하여야 하는 것은 결국 기업의 입장에서 융합경영은 지속경영을 위한 과제가 될 것이다. 따라서 본 연구에서는 기업의 융합경영 필요성에 근거를 두고 기업의 융합경영 구성요소가 품질혁신에 어떠한 영향을 미치는 지를 살펴보고자 한다. 연구 결과, 융합경영 구성요소인 내부요인, 외부요인, 핵심요인 모두 품질혁신에 영향을 미치는 것으로 나타났다. 세부적으로는 융합경영 내부요인은 리더십, 리스크관리요인이 긍정적으로 영향을 미치는 것으로 나타났으며, 외부요인은 지식공유요인, 인프라요인이 긍정적으로 영향을 미치는 것으로 나타났다. 마지막으로 핵심요인은 기술개발요인, 교육학습요인이 긍정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 향후 융합경영을 통한 기업의 경쟁력 강화의 큰 영향요인이 될 것으로 사료되며 향후 기업의 융합경영을 위한 전략적 기초로 활용될 것이다.

In order to increase the efficiency of LED, transparent electrodes should be also developed. also suitable anti-reflection coating (ARC) is necessary for practical device applications. In our paper, Al-doped ZnO (AZO) films were fabricated by sputtering on GaP substrate(wavelength:620nm). Choosing optimum substrate temperature and sputtering rate, high quality AZO films were formed. We confirmed that the surface and electrical properties, which implemented using the methods of AFM, Hall measurement. The properties of AZO thin films especially depended on the thickness. We presumed that the change of the increase the external quantum efficiency of LED according to the AZO thin film of thickness.

The purpose of this study is to evaluate the effectiveness in the lighting performance of mixed type light-shelf, by comparing and analyzing the internal light-shelf, external light-shelf, and mixed-type light-shelf. The performance of light-shelf was evaluated according to the angle of light-shelf at summer solstice, winter solstice, vernal equinox, and autumn equinox. The comparative analysis between the internal light-shelf, external light-shelf, and mixed-type light-shelf was carried out using the performance evaluation and analysis method. The result of performance evaluation is shown as follows. The mixed type light-shelf showed the highest lighting performance all at summer solstice, winter solstice, vernal equinox, and autumn equinox, followed by the external light-shelf and the internal light-shelf in the same order. The mixed type light-shelf was the most favorable for bringing daylight to indoors by adjusting the angle of light-shelf, and it also showed the highest lighting performance in terms of uniformity ratio of illumination which indicates the quality of light.

The residence plan of Korea has been formed with bias for quantitative growth and uniformity failing at obtaining human value. Also, rapid growth brought about severe problems of deteriorated human life and destruction of environment. The solution for these problems is pursued in many directions, but there is short of active plan yet. The residence shall develop into new direction to satisfy the demand by reflecting society and culture as well as residents. This study examines external design with symbolic representation of regional feature as an alternative for uniform residence environment problem. This study will be a basic data upon suggesting the direction for planning high quality residence environment. This study examined the elements which form external space of residence complex, designed plan for external space of residence complex, and examined how to reflect regional feature which is important element of local community and culture on the space plan for residence complex based on the evaluation by local residents centered on Gimcheon-si, Gyeongbuk which just started local specialty by fostering. 'Special Area for Grape Industry.'

Formant frequencies depend on the position of tongue, the shape of lips, and larynx. In the auditory system, the external ear canal is an open-end resonator, which can modify the voice characteristics. This study investigates the effect of the real ear on formant frequencies. Fifteen subjects ranging from 22 to 30 years of age participated in the study. This study employed three corner vowels: the low central vowel /a/, the high front vowel /i/, and the high back vowel /u/. For this study, the voice of a well-educated undergraduate who majored in speech-language pathology, was recorded with a high performance condenser microphone placed in the upper pinna and in the ear canal. Paired t-test showed that there were significant difference in the formant frequencies of F1, F2, F3, and F4 between the free field and the real ear. For /a/, all formant frequencies decreased significantly in the real ear. For /i/, F2 increased and F3 and F4 decreased. For /u/, F1 and F2 increased, but F3 and F4 decreased. It seems that these voice modifications in the real ear contribute to interpreting voice quality and understanding speech, timbre, and individual characteristics, which are influenced by the shape of the outer ear and external ear canal in such a way that formant frequencies become centralized in the vowel space.

Objectives: The obturation quality of MTA, Biodentine, Total Fill BC root canal sealer (RCS), and warm gutta-percha (WGP) in teeth with simulated internal root resorption (IRR) was evaluated by using micro-computed tomography. Materials and Methods: Standardized IRR cavities were created using 40 extracted maxillary central incisor teeth and randomly assigned into 4 groups (n = 10). IRR cavities were filled with MTA, Biodentine, Total Fill BC RCS (bulk-fill form) and WGP + Total Fill BC RCS. Percentage of voids between resorptive cavity walls and obturation material (external void), and inside the filling materials (internal voids) were measured. Results: Total Fill BC sealer in the bulk-fill form presented significantly highest values of external and internal void percentages (p < 0.05). Biodentine showed a significantly lowest external void percentage (p < 0.05). WGP + Total Fill BC RCS presented significantly lower values of internal void percentages than all groups (p < 0.05), except Biodentine (p > 0.05). Conclusion: None of the filling materials were created void-free obturation in resorption cavities. Biodentine may favor its application in teeth with IRR over Angelus MTA and bulkfill form of Total Fill BC.

방울토마토의 수경재배시 과실의 외형형질을 비파괴적으로 추정하고, 이를 검정하였다. ‘Chelseamini’와 ‘뽀뽀’에 비해 ‘Minicarol’의 외형상의 크기(과장, 과폭, 과중, 과실부피)가 특히 작았다. 토마토 과실의 외형형질 간에는 고도의 상관이 인정되어 과실의 생장은 길이생장과 부피생장과 균형있게 이루어지는 것으로 나타났다. 과실의 체적 및 무게는 다음 식으로 추정 가능하였다. 과실의 체적=0.071$\times$(과장+과폭)$^3$＋0.451, 과실의 무게 =0.072$\times$(과장+과폭)$^3$＋0.542. 1993-1994년에 수확한 과실도 이 식으로 설명되었다.

Purpose: The purpose of the study was to compare the ability of college students to use automated external defibrillators (AED) and to provide a basic data for helping laypersons easily apply the AED. Methods: The subjects were randomly assigned to instruction groups. One group was instructed by pictures (group P), one by videos (group M), and one by telephone dispatchers (group D), Without employing cardiopulmonary resuscitation, a single rescuer was asked to apply defibrillation to a mannequin for practice in accordance with the instructions assigned to each group. Results: Regarding the proper pad attachment of the AED, group P followed the instruction $0.31{\pm}0.47times$, group M, $0.81{\pm}0.40times$, and group D $0.69{\pm}0.47times$. Regarding the instruction of taking the hand off a patient for analyzing cardiac rhythm and the instruction of taking the hand off a patient before defibrillation, group P did not follow the instruction; group M followed the instructions $0.50{\pm}0.51times$; and group D followed all instructions at all times. Conclusion: If a dispatcher gives real-time instructions for using an AED to laypersons wtih no experience at the time of AED use, the quality of laypersons' AED use will greatly improve.

This study investigated interactions between the internal-external wave field of a permeable coastal structure consisting of rubble. The study examined the application criteria of an existing numerical model (CADMAS-SURF V.4.0) and proposed a modified method to provide reasonable results. In particular, the study focused on and emphasized the water surface profiles in front of a structure, wave run-up/run-down on a slope, and internal water level fluctuations due to the drag coefficient and porosity of a rubble mound structure. In conclusion, the result show that when the vertical fluctuations of the internal water levels in permeable coastal structures exhibited high-quality representation. Sane responses can be seen for wave run-up/run-down characteristics on its slopes.
