Objectives: This study investigated the effect of mentoring function on job motivation and nursing performance through self-efficacy and outcome expectation. Methods: It was conducted with 226 nurses working in the 5 hospitals of B and G cities. The collected data were analyzed using SPSS Windows 18.0 and AMOS 16.0. Results: Mentoring was found to have a direct effect on outcome expectation (β = 0.314, p < 0.001), and outcome expectation had a direct effect on job motivation (β = −0.333, p < 0.001) and nursing performance (β = 0.341, p < 0.001). Job motivation was found to affect nursing performance (β = 0.268, p < 0.001). Conclusions: The results of this study suggest that mentoring function plays an important role in improving nursing performance, so it is necessary to develop and apply a mentoring program for nurses.

Spinal arteriovenous fistula is the most common vascular malformation of the spinal cord and causes progressive impairment like paraplegia or tetraplegia. Diagnosis of the disease is often challenging because its heterogeneous presentation mimics those of other neurological disorders, such as lumbosacral radiculopathy or peripheral polyneuropathy. Here we report a case of thoracic myelopathy resulting from spinal arteriovenous fistula in a patient treated with chemotherapy. In our clinic, he was diagnosed with spinal arteriovenous fistulas through magnetic resonance imaging and spinal angiography. Electromyography was used to evaluate the clinical features of the patient. Subsequently, he underwent surgery and was transferred to our outpatient department to continue rehabilitation therapy. Eventually, the motor power grade in his lower extremities improved from poor to fair and he was able to walk independently with a wheel walker.

Dance with musical-instruments shows that dance and music are combined in dance with musical-instruments. We can discuss about the border of dance and music and examine the total performing art work through it. There are about 20 dances with musical-instruments in Korea. These dances can be recognised whether instruments-playing one or not. Most of them play percussion instruments and only 2 pieces – which are not playing the instruments – use wind instruments. It shows that dance and music are combined by rhythm. And the not-playing–instruments dance implying that musical-instruments could be used as symbols in dance. As a result, the dance with musical-instruments clearly shows that dance encompasses body movement, music and narration. Actually, it is the concept of Ak(樂, gaku in Japanese and yue in Chinese).
미세피치용 EPIG/DEG 표면처리와 플립칩 접합 계면에서의 NCA 필러트랩 연구

최근 전자 패키징 기술은 IoT, high-performance computing 및 모바일 전자기기 등 반도체 개발로 인해 소형화 및 고성능이 요구되어 있다. 이에 따라 플립칩 범프 I/O 수는 증가하고, 범프 피치는 감소하고 있다. 기존에 칩과 기판을 접합하기 위해 사용하던 재료 들은 미세화 되는 범프피치를 대응하기 위해 대체되어야 한다. 접합재료로써 언더필의 경우 non-conductive adhesive(NCA)로, 표면처리로는 electroless nickel electroless palladium immersion gold(ENPIG)에서 Ni-free인 electroless palladium immersion gold(EPIG)와 direct electroless gold(DEG)로 대체되어야 한다. 여기서 NCA를 사용하는 플립칩 접합공정은 표면처리의 거칠기에 따라 플립칩 접합부 전기적 특성에 영향을 주는 요소이며, 새롭게 적용되는 EPIG 및 DEG의 거칠기에 따른 필러 트랩 연구가 필요하다. 따라서 본 연구에서는 ENEPIG, EPIG 및 DEG 표면처리에 따른 거칠기 변화를 관찰하였으며, 이를 바탕으로 NCA 필러 트랩에 대한 평가를 수행하였다. ENEPIG의 경우, EPIG와 DEG 표면처리보다 다소 낮은 거칠기를 나타냈다. 이는 5 ㎛ 이상의 두꺼운 Ni 도금층으로 인해 기존에 에칭된 Cu 표면 거칠기를 감소시킴으로써 ENEPIG의 표면거칠기 또한 감소하였지만, 범프의 미세 피치는 줄일 수 없는 문제점이 있다. 그러나 EPIG의 경우, Pd 도금층 두께를 0.2 ㎛까지 증가시킴으로써 기존에 에칭된 Cu 표면 거칠기를 효과적으로 감소시키는 것을 확인할 수 있었다. 이렇게 감소된 거칠기는 NCA 및 필러 트랩을 줄일 수 있으며, 접합부의 접촉저항 또한 감소시키는 효과를 나타냈다. 비록 EPIG와 DEG 표면처리에 따른 표면 거칠기는 ENEPIG 보다 다소 높을지라도, ENEPIG에서 해결할 수 없는 문제점을 보완할 수 있다. 위와 같은 결과를 바탕으로 표면처리에 따른 플립칩 접합부 신뢰성에 끼치는 영향에 대해서도 논의할 것이다.

Purpose: Many topical agents had been used for contaminated wound treatment. Although antimicrobial ointments were widely used as topical agents, their comparative antibacterial and wound healing effects were largely unreported. The purpose of this study was to compare antibacterial effects and wound healing effects of common topical ointments on infected full thickness skin defect in the mouse. Methods: One full thickness skin defects in the mice (n=60) were developed on the back and left open for twenty-four hours. Sixty mice were divided into four groups: group B (dressing with Bactroban$^{(R)}$, n=15), group I (dressing with Iodosorb$^{(R)}$, n=15), group T (dressing with Terramycin$^{(R)}$, n=15), group G (control group, dressing with dry gauze, n=15). The size of wound defects and the grades of wound healing were evaluated at 4, 7, 10 days, and antibacterial effect was evaluated with restricted zone in Mueller Hinton agar by disk diffusion method. After the wound was left open for twenty-four hours, many Staphylococcus aureus was cultured. The wound defect size was decreased in order of Bactroban$^{(R)}$ (B), Iodosorb$^{(R)}$ (I), Terramycin$^{(R)}$ and gauze dressing group in all days, but difference among experimental groups was not statistically significant. The grade score of wound healing was increased in order of Bactroban$^{(R)}$, Iodosorb$^{(R)}$, Terramycin$^{(R)}$ and gauze dressing group, and the difference was statistically significant. Antibacterial effect for was increased in order of Bactroban$^{(R)}$, Iodosorb$^{(R)}$, Terramycin$^{(R)}$ and gauze dressing group, and the difference was statistically significant. Conclusion: Topical antimicrobial ointments application was effective against wound infections by S. aureus. Bactroban$^{(R)}$ may be an optimal topical treatment for infected wounds according to this study. However, further study is necessary to evaluate the clinical efficacy of antimicrobial ointments and to search for the mechanisms that explain their effects.

Clozapine is a well-known antipsychotic which causes hematologic adverse effects, specifically neutropenia and agranulocytosis (1–3% of patients). However, reports on blood dyscrasias like anemia and thrombocytosis after clozapine treatment are extremely rare. In some cases re-challenge of clozapine could lead to hematopoietic abnormality related to thrombocytopenia or thrombocytosis, which may be a result of an immune reaction. This case report suggests that clinicians should monitor platelet count after re-treatment with clozapine.

A system dynamics model is developed to investigated the applicability of the agent based modeling concept in the system dynamics model. The assumed problem is to forecast the size and structure of the organization with the developing market environment. The agent based modeling concept is applied to the organization part, and the other parts of the model such as market, facilities, etc. are developed with traditional system dynamics technique. The simulation results show the agent based modeling part can be combined with the traditional system dynamics modeling with more precisions. However, the complexity increases and the simulation times are longer than those of the traditional method.
