In this paper, embedded spiral inductors are investigated into the PCB substrate for low cost RF SOP applications. The spiral inductors designed with geometrical variations were simulated, fabricated, measured, and characterized by using 3D EM simulator, 8 layered PCB standard process and HP 8510B network analyzer for verifying their applicability. The fabricated embedded spiral inductor has inductance of 9.4nH at 800㎒, maximum quality factor of 64.8 at 1.09㎓ and self resonant frequency of 3.93㎓, respectively. As the measured inductances and quality factors are well matched with simulated ones. PCB embedded spiral inductors are promising for advanced electronic systems with various functionality, low cost, small size and volume.

Pseudomonas carboxydohydrogena와 Pseudomonas carboxydovorans의 일산화탄소 산화효소는 세가지 종류의 소단위로 구성 (85,000, 28,000 또는 25,000, 14,000) 되어 있음이 확실히 밝혀졌다. 이와 같은 소단위 구성양상은 효소의 분석방법이나 이 효소를 유도하기 위한 배지의 조성에 의해 영향을 받지 않고 항상 일정하였다. Three kinds of non-identical subunits were found to be present in carbon monoxide dehydrogenases from Pseudomonas carboxydohydrogena (85,000, 28,000, and 14,000) and Pseudomonas carboxydovorans (85,000, 25,000, and 14,000). The subunit pattern of these enzymes was constant and was not changed either by analysis of the enzyme under different conditions or by inducing the enzymes under variable culture conditions.

Purpose: The purpose of this study is to obtain comprehensive understanding of Korean middle-age men's experience in their andropause. The findings of this study will provide supportive data for development of nursing interventions. Methods: This study is explored by hermeneutic phenomenological analytic method suggested by van Manen. Data was collected through in-depth interviews with 7 middle aged men between July and September, 2017. Before the interviews, preliminary questionnaire was preformed for all participants. Results: The analysis produced five themes: 'My body is getting weaker than before', 'A sense of despondency with current life', 'Regarding andropause not as much important as menopause', 'The obscurity of one's life about andropause', 'Cut off andropause from life'. Conclusion: This study explored Korean middle-age men's experience in their andropause. Although most participants experienced physical and psychological symptoms, they denied that they are andropause. Moreover, they lacked knowledge and showed attitude of indifference. In addition, Andropause is not as commonly recognized in the society of Korea. Even if they perceive it, they cannot reveal the fact and respond poorly. It brings up the necessity to provide proper information and education. A variety of nursing interventions are also required for the men for their physical or mental recovery and health care. Therefore, this study offers the deep understanding of the significance and nature of the experience in andropause. Furthermore, this study may put foundation for development in nursing care of studies of this subject.
